Today we will help you comprehensively interpret the structural characteristics, manufacturing, and usage details of ceramic atomization cores

There is a very important component in vapes: the atomizer, which contains an atomizer core. It is through this atomizer core that the e-liquid is atomized by being electrically heated. For atomizers, the atomizing core is a core component. Generally speaking, atomization cores can be divided into ceramic atomization cores and cotton cores. Cotton cores are usually for nicotine fruit flavor vapes. And the heating coil usually designed to mesh wire. Due to the different boiling points of e-liquids, cannabis oils commonly use ceramic atomization cores. And this one be used for CBD oil, THC oil, and other cannabis extract.
With the increase of pod replacement products on the market, microporous ceramic atomization cores are favored by more people.

Structure and characteristics of microporous ceramic atomization core

At present, most mainstream pod systems are equipped with microporous ceramic atomization cores, providing users with a high-quality experience. Micro porous ceramics refer to ceramic bodies containing a large number of open or closed micro pores inside or on the surface of the ceramic, with pore sizes generally in the micrometer or sub micrometer range. It is a functional structural ceramic. The micropores of microporous ceramics are very small and can be calculated in micrometers and nanometers. Micro porous ceramics have good adsorption, breathability, corrosion resistance, environmental compatibility, biocompatibility, etc.

The strong adsorption, high temperature resistance, ability to make co fired circuits, safety and non toxicity of microporous ceramics can meet the requirements for making electronic cigarette cores. The vape core of microporous ceramics has the following technical characteristics:
• The surface of microporous ceramics has hygroscopicity, and by reasonably controlling the porosity, microporous size, specific surface area, and moisture content of microporous ceramics, it is possible to adjust the dryness and humidity of local areas
• It can achieve smooth supply of e-liquid to the atomizer, with stable and efficient liquid guiding and locking functions, improving the atomization efficiency of e-liquid. Compared with traditional cotton wrapped atomization cores, it has a better taste and experience, and is less prone to oil leakage
• Due to the high temperature resistance of ceramics themselves, even if there is a momentary high temperature phenomenon, there will be no burning of cotton as in traditional cotton wrapping processes. And its temperature will rise faster, with better temperature uniformity and more precise temperature range control
• Porous ceramics, due to their rich micropores and special sintering process to control porosity, can adjust the size of aerosol particles in the mist freely. This ceramic has the characteristics of low thermal conductivity, low density, and low specific heat capacity. Due to its material properties, the temperature field of the liquid during atomization is relatively uniform, and atomization is more complete per unit time, bringing users a better experience with higher atomization efficiency
• Its high temperature resistance and corrosion resistance also improve the service life of the entire product.

Preparation method of vaping ceramic core of cannabis style oils CBD THC

There are currently four basic preparation methods, namely pore forming agent method, partial sintering method, template substitution method, and direct foaming method.
1. The pore forming agent method is the most commonly used method, which involves adding volatile or flammable pore forming agents to ceramic materials, and using these pore forming agents to evaporate or burn out at high temperatures, leaving pores in the ceramic body. Common pore forming agents include: organic resin microspheres, organic fibers, carbon fibers, carbon powder, starch, sawdust, polymethyl methacrylate, methyl cellulose, etc.
2. Partial sintering method refers to the process where powder particles are connected to each other through diffusion or evaporation condensation at high temperatures, but complete densification is not achieved, resulting in the formation of a uniform porous structure between particles. The porosity of the porous ceramics prepared by this method is generally less than 50%, and the particles are 2-5 times larger than the pore size. They are often used in molecular sieves, water purification membranes, and other fields.
3. Template replacement method, also known as organic foam impregnation method, is prepared by impregnating organic foam (usually spongy polyurethane) with prepared ceramic slurry, then burning organic matter and sintering ceramic body to obtain porous ceramic products. Sol gel or colloidal solution can also be used to dip and coat organic foam instead of ceramic slurry.
This method has the advantages of simple process, convenient operation, no need for complex equipment, and low preparation cost. It is an effective and economically practical method for preparing high porosity (70-95%) porous ceramics.
4. The direct foaming method is to produce dispersed gas phase in the ceramic suspension, which is generally composed of ceramic materials, water, adhesives, surfactants and gel. This process has been used to produce porous ceramics such as zirconia and alumina, with porosity ranging from 20-80%. For example, Suelen Barg, a German researcher, disperses alkanes into ceramic slurry, adds dispersant to make alkanes form a uniform and stable lotion, and finally makes porous alumina ceramic filter with porosity up to 90%.

What are the brands of ceramic atomizing cores

In the past three years, vape pod systems have gained market favor. Most CBD THC vape cartridges are mainly use ceramic atomizing cores. So the demand for ceramic cores in the market is increasing, and there are more and more companies supplying ceramic cores.
China has a total production volume of over 95% of vapes and accessories exported globally, making it a global vape industry base. As the largest research and production city for vapes, Shenzhen has undoubtedly produced many vape brands. Next, we will list the best CBD THC atomizing core brands in the cannabis field.

Today, we will explain to you some of the most common issues encountered during the use of e-liquid. I hope it can bring you some help.

Why does vaping cause dry mouth?

Yes, because the main components of e-liquid, glycerol (VG) and propylene glycol (PG), are highly absorbent substances. Any advertisement that says that e-liquid doesn’t dry your mouth is not trustworthy. It’s just that everyone’s ability to secrete saliva in their mouth is different. Some people have strong secretion ability, so they won’t feel dry mouth and tongue. If you happen to belong to the group of people with weak secretion ability, just drink plenty of water. You don’t have to think about how to change e-liquid to avoid feeling dry. The composition of e-liquid is like this, and no one can change it.

what is decanting e-liquid? Why need to decant e-liquid

E-liquid is composed of various polymer composite chemicals. It also includes various essence, including oily substances and water-based substances. Although their densities are very close, there will still be separation phenomena, just like water and oil. Decanting e-liquid is to allow them to fully integrate with each other and ultimately achieve balance.

Is it difficult to DIY e-liquid? Is it safe?

DIY e-liquid by oneself is not very difficult. After selecting the materials, just mix them according to the formula. The real risk of DIY e-liquid lies in the credibility of the raw materials. Please try to choose suppliers with FDA, USP, and EP certifications. Pursuing low prices blindly is definitely not a good thing. You know, it is something that is inhaled into the lungs.

Why my e-liquid has no taste when I smoke it in my mouth?

Everyone’s feelings towards e-liquid are not exactly the same. It is completely normal for some heavily addicted players to feel that vapes are not as powerful or as expected. But sometimes novice players have too little smoke output due to equipment settings issues. Due to a lack of initial sensory experience with vapes, it is common to mistakenly believe that they are tasteless. To be honest, a successfully blended vape should have a rich and sweet overall taste, apart from differences in taste.

Why is the taste of smoking with this atomizer not as good as the other one?

An excellent atomizer may have its own style depending on the degree of intake and atomization. Many players have 4 or 5 atomizers, but most people who frequently use only one. Because that atomizer fits perfectly with his own feelings. So when novice players choose atomizers, they should try to choose popular ones and not be influenced by appearance and advertising slogans. Because the vast majority of people’s choices are still worth considering.

What should I do if the e-liquid is too sweet and greasy?

Some e-liquids have a sweet and greasy taste, indicating that this flavor may not be suitable for you. It may also be because the decanting process of e-liquid was not fully completed before leaving the factory. You can choose to let it sit for two weeks before tasting, or add VG to dilute the flavor yourself, or simply choose a different flavor. So when trying new e-liquid for the first time, we do not recommend buying many large bottles at once because that taste may not be suitable for you. Experienced people usually buy small bottles first, decide which flavor to smoke, and then buy several larger bottles of the same flavor. Old hands are old hands.

What is throat hit sensation?

This is a difficult question to answer. The moment smoke is inhaled from the outlet, the nicotine component it contains will cause a slight irritation to your throat. Similar to the stimulating sensation when smoking, but cigarettes not only contain nicotine but also many other chemical components during combustion, resulting in a greater sense of stimulation. However, vapes do not have such a strong sense of stimulation, and can only simulate the feeling of entering a cigarette. It’s not right to say that it feels exactly the same as cigarettes. So when you purchase vapes, if any merchant claims that they taste the same as real cigarettes, please be sure to keep your eyes open.

What are VG, PG?

VG stands for Vegetable Glycerin. Also known as vegetable glycerin, also known as glycerol. Please refer to Wiki Pedia for specific chemical instructions. Glycerol is one of the two basic solutions that make up smoke and is also the main source of clouds. The higher the glycerol content, the greater the clouds produced by e-liquid. Generally, drip oil players use pure VG e-liquid when playing big clouds or competing. PG refers to Propylene Glycol, also known as propylene glycol. It is another basic solution that makes up e-liquid. Its role in tobacco oil is to dissolve essence and mix other solutions, while also providing a certain sense of throat hit.

Why did I faint after taking a few puffs?

Everyone’s tolerance to nicotine is different. E-liquid itself is a product containing nicotine. If you feel dizzy while smoking vapes, you can try low nicotine e-liquid or nicotine free e-liquid. If you still feel dizzy, please stop using vape products immediately, as health cannot be taken lightly.

What concentration of nicotine is better to choose?

We cannot advise you on the specific concentration of e-liquid that is better. At present, most electronic players choose 2MG, which is sufficient for both throat sensation and taste. But if you are just starting to quit smoking, please choose some high concentration ones so that your withdrawal symptoms will not be so strong. Quit smoking is a slow and arduous process, let’s take it step by step.

The relationship between nicotine solution and throat hit sensation?

The higher the nicotine content, the stronger the throat hit and the greater the stimulation. It is recommended that most players try 2GM first, and if they feel it is not enough, then add more. After all, we are trying to quit smoking, not for the thrill of it.

Do I need to clean the oil tank before refill e-liquid?

Cleaning the oil tank before refill e-liquid is a good habit. As long as you are not a particularly particular person, there is not a problem with not cleaning. Regular maintenance of equipment is sufficient.

What’s wrong with choking?

The reason for choking is usually due to the first few mouthfuls that have just been assembled. It is because the e-liquid on the new cotton core was not fully evaporated before oil injection, and was directly sucked up by you through the vent hole. Before closing the oil tank, please drop a small amount of e-liquid on the new cotton core and heat it up to fully short time burn. After that, this phenomenon will no longer occur.

Is it better to keep e-liquid for a longer period of time?

Absolutely not. Some e-liquids become softer with decanting oil awakening time, but not all e-liquids are the same. Some e-liquids may lose some of their expected flavor after being left for a long time. Any e-liquid should be used up as soon as possible after opening, and e-liquid is generally well decanted before leaving the factory, so there is no need to decant it too much.

Does good e-liquid require a good atomizer?

There is no requirement to do this, but a good atomizer is more likely to fully utilize the flavor of your e-liquid, especially high-end e-liquid.

How to judge the quality of e-liquid and whether it is suitable for oneself?

After all, e-liquid is a difficult existence to match everyone’s taste. You may not necessarily like what I like. Try different brands and flavors, and gradually you will find the one that suits you. That’s how we all come together. Try buying a small bottle of 10ML first.

Why does the vaping smell like a rust when I smoking?

That’s because cotton is not filled with hot threads, or the oil flow is not smooth. After the hot threads evaporate the e-liquid in an instant, there is no e-liquid subsequent supply, so there will be a smell of dry hot threads. Adjusting the cotton core can generally solve the problem.

Why does my tongue feel numb when I smoke vapes?

The e-liquid is incompletely atomized in the atomizer, and some of the e-liquid was carried into the mouth, causing a tingling sensation on the tongue. Electronic cigarette is in the form of vapor, with some condensation in the mouth, and a slight tingling sensation has little effect. Try increasing the output power to ensure complete atomization of the e-liquid.

Why does the same one e-liquid taste different on the same one atomizer?

Every time you adjust the atomizer, even if the settings are the same, there will be slight differences. However, the main reason that can affect the taste is that the cotton core is constantly heated repeatedly, and some parts are still burnt. If it is a new cotton core with a significant change in taste, check if the e-liquid has expired or if there are suspended particles that have deteriorated.

Why do some e-liquids damage the atomization tank?

At present, only high VG content e-liquids may damage the acrylic oil tank. VG can cause corrosion of acrylic materials. If you choose to use an acrylic tank, please be sure to pay attention to the VG content of e-liquid.

The above is a summary of the common problems encountered by vape users by our engineers. If you have any other different questions, please contact us. We will revise and supplement this article. Let everyone have a better and better atomization experience

Eliquid as the soul of vape

E-liquids have more than 8000 flavors, ranging from various fruits to coffee, bread, and toast. As long as you can find the corresponding e-liquid, you can basically find it.

The components of e-liquid

In fact, the ingredients of tobacco oil are very simple. There are only four kinds: propylene glycol (PG),vegetable glycerin (VG),nicotine and edible essence.

1. Propylene glycol is a common drug and food additive. It is hygroscopic, slightly sweet, colorless, odorless, transparent, and has good fluidity. The definition of PG by the US Food and Drug Administration (FDA) is “generally safe for human consumption”. As one of the basic components of electronic tobacco oil, PG is mainly used as the carrier of essence to enhance the taste of tobacco oil. After heating, it will produce a small amount of fog with a certain sense of throat.

2. Vegetable glycerin, like PG. VG is also a widely used raw material in daily life. Upon careful observation, it can be noticed that many snacks have ingredients labeled as “propylene glycol” and “propylene glycol” on their packaging. People who particularly enjoy sweet foods also consume a large amount of VG. Because most snacks such as cakes and desserts contain VG, and VG’s main function in e-liquid is to generate mist. VG generates a large amount of mist after heating. Generally, to increase the smoke volume, adding a large amount of VG directly can achieve the desired effect. VG has high moisture absorption and is very viscous. If the fluidity of a e-liquid is poor, it is definitely due to a high VG ratio. The smoke in this e-liquid is very strong, but the relative flavor is slightly inferior, and the throat sensation is slightly weaker.

3. Nicotine, as is well known, is the main component of tobacco and the primary reason why many people smoke. In addition to relieving smoking addiction, nicotine can also produce a unique throat sensation that many smokers enjoy. However, due to the toxicity of pure nicotine when it comes into contact with the skin, it is generally dissolved in VG (vegetable glycerin) in e-liquid. This can ensure the volatility of nicotine while avoiding the risk of direct contact with the skin. Meanwhile, vegetable glycerin is also one of the main components of e-liquid, which can help stabilize the nicotine solution, making the smoke softer and less irritating to the throat.

4. The eating essence is the soul of tobacco oil, which determines the flavor of tobacco oil. Generally, the essence formula of tobacco oil with unique flavor is also complex.

The production process of e-liquid

There are generally two ways to concoct e-liquid: one is using measuring tools, and the other is using electronic scales. The difference between them is whether the unit of measurement is capacity or weight. Then, we will introduce the use of electronic scales to mix e-liquid.

Firstly, add VG solution of nicotine to a specialized container. Due to the high viscosity of nicotine, it is easy to sink to the bottom during the preparation process. Therefore, remember to shake it for a period of time before adding.

Then, add essence, PG and VG into the container in turn.

In addition to trace nicotine, the proportion of the above four ingredients normally accounts for 10% -15% of essence. The ratio of PG and VG is adjusted according to actual needs. If there is more PG, there will be a stronger throat sensation and lighter smoke, while VG is just the opposite. Friends who like big clouds will choose e-liquid with more VG, while small clouds mostly adopts a 50:50 ratio to achieve a balance between throat sensation and smoke volume.

After pouring all four types of raw materials in, they were clearly divided into four layers due to their different densities.

At this time point, shaking is needed to fully integrate them. After shaking, it is necessary to let it rest for optimal results. Then, the e-liquid has been made out.

Although the production process of tobacco oil is relatively simple, it is difficult to accurately master the proportion of essence to meet different taste needs. In fact, the essence in the tobacco oil and perfume can be divided into front and base note.

However, the tobacco oil with complex taste will be mixed with essence of various ingredients, and the proper proportion can only be obtained through constant attempts. For example, the following essence mix can be divided into seven categories: top 1, top 2, support, complimentary 1, complimentary 2, base 1, and base 2.

Precautions for modulating e-liquid

The preparation of e-liquid may seem simple, requiring only conventional tools, but the prerequisite is sufficient professional knowledge. The ratio of PG to VG, nicotine form, and the selection and proportion of essence are all important if you want to produce “suitable clouds”, “good taste”, “enough to hit the throat” and “not choke the nose” tobacco eliquid. Only by mastering these key elements can satisfactory e-liquid be formulated. The preparation of vape e-liquid involves many professional considerations, and the entire preparation process involves precise control of the mixing and proportion of multiple components. Therefore, it is not recommended to self prepare e-liquid at home. Choosing professionally prepared e-liquid can ensure health and safety. At the same time, it is important to choose reputable e-liquid brands and sales channels to avoid purchasing counterfeit and inferior e-liquid products.

As a new type of fashionable electronic product, the market consumption value of vapes continues to rise every year. Despite various policies being introduced to regulate and even restrict. However, as a highly disruptive invention, vapes are irresistible to consumers.

The “sweet, cool, and sour” sensation of vaping is a complex sensory experience. Its mechanism profoundly affects the attractiveness of the product

The fruit flavor of vapes is mainly due to the addition of food grade essence. These essence are similar to those used in food and drinks. After atomization and heating, they will produce various fruit flavors.

1. Food grade essence: The flavor in e-liquid mainly comes from synthetic food grade essence, such as strawberry, mango, mint, etc. These essence are widely used in the food industry with high safety standards. But for the long-term effects of inhalation into the lungs, that still need more research.
2. Atomization working principle: Vape generates aerosols by heating the e-liquid (mainly containing propylene glycol, vegetable glycerin, essence and nicotine). And essence forms special flavor after heated and volatilized.

A. Sweetness production: receptor activation of non nutritive sweeteners

The normal sweet taste transmission pathway is: a. Detection and conversion (on the tongue) of sweet substances (such as sugar) dissolved in saliva, and binding to “receptors” on the taste buds that specifically detect sweetness. This combination triggers the generation of electrical signals inside taste bud cells. The electrical signals (action potentials) generated by the signal upload (through nerves) are immediately captured by the taste nerves (mainly facial nerves and glossopharyngeal nerves) connected to it, and quickly transmit the “sweet” signal to the brain like electrical wires. c. Recognition and perception (in the brain) signals first reach the brainstem for preliminary processing, and then upload to the taste cortex and emotion/reward center of the brain. Here, the brain ultimately recognizes this as a “sweet” taste and may generate a pleasurable sensation. The perception of sweetness is mainly mediated by the G protein coupled receptor heterodimer T1R2/T1R3 on type II taste buds in the tongue. The high-strength synthetic sweeteners added to electronic cigarette liquids, such as sucralose and neotame, are their key ligands. After binding to the extracellular domain of the receptor, these molecules activate the intracellular G protein (taste transducer protein), which in turn initiates the phospholipase C – β 2 (PLC – β 2) signaling cascade reaction, ultimately leading to the opening of the transient receptor potential M5 (TRPM5) channel, depolarization of the cell, and release of ATP, activating the taste afferent nerves (facial nerve and glossopharyngeal nerve). Sweetener is not sugar, but it can directly act on receptors to generate neural signals, which are interpreted by the brain as sweetness.

B. Generation of coolness: modulation of temperature sensitive ion channels by cooling agents

The core mechanism of coolness is the pharmacological activation of transient receptor potential M8 (TRPM8) ion channels by cooling agents (such as menthol, WS-3, WS-23). TRPM8 is the primary cold sensing sensor, typically physically activated at temperatures below approximately 26 ℃. The above chemical ligands can serve as allosteric modulators, directly binding to specific sites of channel proteins (such as menthol binding to the S4 transmembrane region), significantly reducing their voltage dependence and temperature activation threshold, allowing them to remain open even at normal body temperature (37 ℃). The opening of the channel leads to the influx of Ca ² ⁺ and Na ⁺, causing depolarization of TRPM8 expressing trigeminal sensory terminals and generating action potentials. This signal is transmitted through the trigeminal nerve and unconditionally interpreted by the central nervous system as a “cold” sensation. In the use of electronic cigarettes, this strong cool sensation input can effectively inhibit the harmful signal transduction of stimulating chemicals (such as free base nicotine and propylene glycol) by the trigeminal nerve in the same area, that is, through sensory gating to achieve local anesthesia and reduce throat irritation.

C. Dual effects of acidity: proton sensing and pH regulation

Sensory sourness: Mediated by hydrogen ions (H ⁺) or organic acid molecules (such as citric acid) in aerosols. H ⁺ can enter the cell through the specialized proton channel OTOP1 on taste bud type III cells, or cause cell depolarization by blocking other potassium channels, activating the sour taste neural pathway. Meanwhile, H ⁺ can also directly stimulate the trigeminal nerve endings, producing sharp chemical sensations. Nicotine bioavailability regulation: Currently, most e-liquids are nicotine salt products, which adjust the pH value of the atomized liquid by adding organic acids such as benzoic acid and lactic acid. In low pH (acidic) environments, free base nicotine combines with H ⁺ to form nicotine salts. This form has the following key characteristics: reduced volatility: reduces losses during transmission. Significant reduction in throat irritation: less irritation to the throat mucosa. The absorption efficiency of the lungs is significantly improved: it is more soluble in the surface fluid of the alveoli and passes through the cell membrane. Its pharmacokinetics show that the blood nicotine concentration rises faster and the peak is higher, simulating the nicotine shock of traditional cigarettes.

A disposable vape is usually called as “All-in-One” (AIO) vape. It because the entire device is a single, self-contained, non-reusable unit. And all its core components permanently fused together.

Here are more of what “All-in-One” means in this context:
Firstly of the “All” that is in “One” Device:
1. Battery is integrated with non-removable.
2. The vape tank containing the pre-filled oils (with CBD THC) is sealed inside.
3. The atomizer heating coil that vaporizeing the oils is built into the pod or device.
4. The part you draw from is fixed to the device.
These components are not serviceable or replaceable. When the oil is exhausted or the battery dies (whichever comes first). You throw the entire device away—as “disposable.”

Secondly Why This Distinction Exists: The Evolution of Vaping
The name of “All-in-One” helps differentiate it from other type of vapes. Other more complex vape styles:
1. Ciga-like (1st Generation vape): Early vape often has separate, small disposable cartridge that attached to a small rechargeable battery. That is not truly “all-in-one.”
2. Modular/Advanced Vape (Box Mod): This has separate, removable component: a large external battery, a refillable tank, and replaceable coils as accessory. The user assembles vape by themself.
3. Pod system (2nd Generation): It is rechargeable device with separate disposable or refillable pods (containing the e-liquid and coil). The battery is reusable, but the pod is replaced.
A disposable vape takes the pod system concept and simplifies it to the extreme: the “pod” and the “battery” are permanently married into one piece of plastic and metal.

Finally Key Takeaway:
1. “Disposable” describes its using case and lifespan (after use it, then discard it).
2. “All-in-One” describes its design and construction (all component is integrated into a single, sealed unit).
3. So, you often see the terms used interchangeably or together: “Disposable AIO vape.”

In summary: All disposable vapes are AIOs, but not all AIOs are disposable (some advanced, reusable vapes also have an integrated, non-removable design). AIO vape device can cover all kinds of cannabis hemp distillates and live resins. And we would like to design different atomizer as ODM project specially for your oils. We have great engineer team of good at this job.

Now, I introduce some of hot selling AID device vapes from my factory. We are AIO device manufacturer have been service for many American cannabis manufacturer and cannabis brand since from 2017. We are looking for a long-term OEM partner. Ours empty disposable vape AIO devices are used with distillates and live resins.

Are you curious about something. China produces so many vapes every year. Do Chinese people smoke vapes themselves?

We are a professional vape factory that produces vapes. I will provide a comprehensive answer to your question and also welcome more professional professionals in the industry to supplement.
In China, the production of vape requires a license from the National Tobacco Administration. This means that only licensed factories can produce vapes.
However, vapes are subdivided into different fields. We all know that a complete vape requires e-liquid inside.
Firstly, for the cannabis industry, China does not have this type of oil. So, many CBD vape factories that produce empty device do not require a license. Strictly speaking, they produce semi-finished products and accessories. Not a true vape. The government has not implemented very strict regulations to require CBD vape factory that produce semi-finished products and accessories to obtain production licenses from the National Tobacco Administration.
Secondly, the same applies to the heated not burnt series e-cigarette. This type of product does not strictly comply with regulations.
Finally, for nicotine vapes, as they contain e-liquid inside the device, they are considered a complete vape product. So factories with production licenses are allowed to produce. And all models, styles need to be registered and filed with the National Tobacco Administration. Otherwise, mass production and export are not allowed.
So nicotine vapes are further divided into fruit flavors and tobacco flavors. Chinese law prohibits the sale of fruit flavored vape in China. Vape with tobacco flavors are legal and allowed for sale after approval.

Selling fruit flavored vape in China is illegal.

Let’s introduce specifically what crimes can be committed when selling fruit flavored vape?

Unlicensed Sales: The “Dual track System of Amount” for Illegal Business Crimes

After the implementation of the “Electronic Cigarette Management Measures” in May 2022, vapes will be included in the tobacco monopoly system. Selling fruit flavored vapes without a license directly violates Article 225 of the Criminal Law for illegal business operations. The filing criteria are determined based on a dual track approach of “sales revenue+profit”:
1. Basic punishment (less than 5 years): Sales revenue ≥ 50000 yuan, or illegal gains ≥ 20000 yuan
2. Heavy punishment (5 years or more): Sales revenue ≥ 250000 yuan, or illegal gains ≥ 100000 yuan

Key details:
1. Inventory included in value: Unsold fruit flavored electronic cigarettes are calculated at market price
2. Online sales are being heavily criticized: transactions on WeChat and Moments are seen as “evading regulation”,
3. License expiration is equivalent to no license

With license: the ‘national standard red line’ of the crime of selling counterfeit and inferior products

Even if holding a Tobacco Monopoly Retail License, selling fruit flavored vapes after October 1, 2022 is still illegal. According to the national standard GB41700-2022, fruit flavored vapes are classified as counterfeit products due to violations of additives, lack of child lock function, and excessive nicotine, triggering Article 140 of the Criminal Law:
1. Registration criteria: Sales revenue ≥ 50000 yuan, or unsold goods value ≥ 150000 yuan
2. Special recognition: Even if the product does not directly harm health, as long as it violates the mandatory standard of “only allowing tobacco flavors”, it constitutes a counterfeit product

Practical traps:
1. Cross selling is considered as counterfeit: Fruit flavored vapes purchased from unauthorized platforms, even if the supplier has a certificate, are still judged as counterfeit due to being “out of the regulatory chain”
2. Accumulated calculation of expired products: In the case, more than 4000 boxes of expired fruit flavored vapes were included in the total value of the goods according to the formula “value of goods=price x quantity”.

Aggravated circumstances:

1. Sales guided by minors
2. Drug related “high vape”
3. Concealed online sales, using “secret code transactions”

The above is the actual situation of vapes in China. Relatively speaking, although China is a major producer of vapes. But the regulation of vape is very strict in China. Since the new regulations were introduced, few consumers have purchased vape products. To be honest, tobacco flavored vapes have a bad taste and do not meet consumers’ preferences.
We rarely see vape consumers in our daily lives, and as a practitioner myself. I use fruit flavored vape without considering tobacco flavor.

With the increasingly strict regulation of vapes in many countries, especially the strict ban on disposable vapes. The sales of disposable vape has declined in some countries, but they have not completely disappeared.
Today we will explore why disposable vape is more popular compared to legal vapes that meet the standards: pod vape and refillable vape.

Firstly, let me briefly introduce the main functions of the rechangeable pod vape system:

1. The battery and atomizer(we usually say pod) parts are separate Batteries can definitely be recharged and reused.
2. Atomizer(we usually say pod) can be a pre-filled e-liquid , most of which are like this. But the fatal flaw is e-liquid leaking. As vape expert with 13 years of experience in the industry. I am certain that 99.99% of pods will leak eliquid. This is a completely unsolvable problem. Due to the inability of the pod to be sealed, an eliuqid hole must be provided to allow the e-liquid to flow onto the heating coil before atomization can be carried out. So imagine bringing a vape from the cold outdoors into a warm home. E-liquid flows out of the oil hole with a certain degree of thermal expansion and contraction.
3. The pod can also be designed to be in an open and refillable state.

Secondly, let’s introduce vapes that can be refilled with eliquid:

1. Generally, it is an integrated design of battery and atomizer.
2. Batteries can be recharged repeatedly.
3. Most of them are made of high-quality silicone material and sealed with plugs on top of the atomizer to plug the eliquid injection hole.
4. The heating wire of the vast majority of atomizers is used after 3 repeated oil injections. The taste of atomized e-liquid gradually deteriorates and the texture deteriorates.
5. A few are rechangeable pod vape with interchangeable design, as mentioned earlier.

Finally, let’s talk about the design of disposable vapes:

1. Using a mesh heating coil wrapped in cotton for better atomization effect and purer taste.
2. The sponge in the e-liquid storage compartment absorbs e-liquid, which is a storage method that greatly reduces eliquid leakage. Basically, there won’t be any e-liquid leakage at all.
3. Integrated design of battery and atomizer, with lower cost.

Below, I will provide a detailed explanation of the advantages of disposable vapes:

1. Convenience

Disposable vape does not require any additional handling. Users only need to open the packaging to use it directly, and discard it after use. Of course, this has also led to a large amount of electronic waste.

2. No maintenance required

Disposable vapes are completely eliminate the hassle of maintenance, allowing users to easily discard used devices without worrying about battery, refueling, or cleaning issues.

3. Convenient to carry

Disposable vapes are small in size, lightweight, and suitable for carrying outside. After use, it can be discarded directly without worrying about eliquid leakage.

4. Price transparency

The price of disposable vape is clear, and a complete user experience can be enjoyed with a one-time purchase. It is suitable for those who occasionally use or want to try electronic cigarettes.

5. Diverse flavor options

Many disposable vape brands have launched a variety of flavors for consumers to choose. It’s meeting the needs of different consumers.

6. Suit for novice users

For users who are just starting to use vapes, disposable vape is a more user-friendly option. It does not require any learning costs and reduces the possibility of operational errors during use.

7. Health and safety issues

Some disposable vape manufacturers design them to be very simple and hygienic, without direct contact with e-liquids during use, making them relatively cleaner and safer.

In the previous article, we mentioned: 2 UK Vape Stores Were Closured 3 Months For Selling Illegal Vapes
Despite strict enforcement of laws prohibiting disposable vapes in the UK.

However, there are still e-cigarette sellers who take risks by selling disposable vapes. Because consumers like it, the profit is very considerable.

Regarding the sale of vapes in the UK, they must be designed in compliance and certified in the UK Medicines and Healthcare products Regulatory Agency(MHRA)

Exploring the working principle of steam type vapings

The new tobacco products are divided into heated no burnt electronic cigarettes and steam style vapes. Heating not burn electronic cigarettes are aerosols containing nicotine produced by heating tobacco flakes to 200-300 ℃. Steam type vapes are made by extracting nicotine from tobacco leaves into e-liquid, and then using electrical energy to drive metal wires to generate heat to atomize e-liquid, producing aerosols containing nicotine. This study mainly focuses on the atomization process of steam type vapes, exploring the main factors affecting the atomization process from the aspects of heating wire, e-liquid, oil conducting cotton, and heat transfer path during atomization.

The heating wire material and heating characteristics of vapes

The equation for the steady-state heat transfer process of a heating wire can be obtained from Fourier’s law of thermal conductivity as follows:
Φ=-λ · A · gradt

• Φ is the heat transferred during the thermal conduction process, measured in (W).
• λ is the thermal conductivity of the material, measured in (W/m ·° C).
• A is the cross-sectional area, measured in m㎡.

The non steady state heat conduction equation is:
∂t/∂τ = a * (∂²t/∂x² + ∂²t/∂y² + ∂²t/∂z²) + Φν / (ρc)
a = λ / (ρc)

• a is the thermal diffusivity of the material.
• ρ is the density of the material, measured in kg/m³.
• is the specific heat capacity of the material, measured in J/kg · °C.
• Φν is the internal heat source, measured in (W).

Thermal diffusivity, also known as thermal conductivity, reflects the speed of material temperature changes. The larger the value of a, the faster the heating rate of the heating wire, and the stronger the explosive force.

For heating wires made of the same material, the higher the input power (Φ ν), the faster the heating rate of the wire. Taking the mesh heating wire as an example, the temperature of the heating zone was measured using an infrared thermal imager at constant powers of 5w, 7w, 9w, and 12w. The average temperature of the heating zone is shown in Picture 1. From the picture, it can be seen that when the power reaches a certain value, continuing to increase the power does not increase the steady-state temperature, and the heating rate does not increase significantly. At this time, the latent heat of phase change absorbed by the liquid to gas state of the e-liquid dominates, and the atomization process enters the steady state. The consumption of e-liquid will increase. If the oil is not guided in time, it is highly likely to cause local high temperatures, resulting in changes in fragrance or even sticking of the core. Therefore, determining the critical power is very important. When the input power is less than the critical power of the atomizer, the power and heating wire play a major role in the atomization process; On the contrary, when the input power is greater than the critical power, the main factor affecting the atomization process is the oil transmission rate of the cotton.

Temperature distribution characteristics of vape heating wire

The overall temperature distribution of the heating wire is mainly determined by the heating zone and the heat dissipation conditions. Taking the mesh wire heating element (Figure 2a) as an example, in the case of no airflow, the temperature measured by the infrared thermometer (Figure 2b) and the numerical simulation results (Figure 2c) show that the temperature distribution decreases from the center to the surrounding areas. The temperature in the heating zone is higher, which is due to the poor heat dissipation conditions at the center, causing heat accumulation.

In the presence of airflow, taking the spiral transverse heating wire as an example, through infrared thermography temperature measurement (Figure 3b) and numerical simulation calculation (Figure 3c), it was found that the high-temperature area is concentrated at the center of the heating wire located above. As air flows in from the bottom, it exchanges heat with the heating wire located below first, and then the airflow continues to flow along both sides, cooling the heating wire on the side. For the heating wire located above, the airflow is difficult to exchange heat with it, so the high-temperature area is concentrated here.

Changing the distribution of heating temperature can be achieved by altering the overall heat exchange conditions of the heating wire. Currently, there are two main ways to make changes: one is to change the heat exchange conditions of the heating wire itself, and the other is to change the external heat exchange conditions..
Changing the self heat exchange conditions of the heating wire can be achieved by adjusting parameters such as the spacing, wire diameter, and angle of the heating wire. Taking the mesh heating wire as an example, as shown in Figures 4a and 4b, changing the spacing of the heating wire can show a change in the temperature distribution of the heating wire. The heat of the heating wire with small spacing accumulates more in the center, so the center temperature is higher than that of the heating wire with large spacing.

There are many methods to change the external heat exchange conditions, such as changing the intake method, atomizing core tube wall material, e-liquid storage, oil guide cotton area, and so on.

Vaping e-liquid and porous substance

The e-liquid is mainly composed of propylene glycol, glycerol, nicotine and essence. During the atomization process, with the increase of temperature, the components in the e-liquid undergo the process of transforming from liquid to gas, and the gas condensation and air form aerosols. The amount and order of atomization of each component directly affect the reduction of aroma and taste.
During the atomization process, e-liquid serves as the source of aroma and smoke, but also exists as a fluid and cold source in the heat and mass transfer process of e-liquid. The higher specific heat capacity and latent heat of vaporization allow e-liquid to absorb more heat, and its viscosity changes with temperature, which in turn affects its fluidity and heat exchange capacity.

Cotton and ceramics are both porous substance that play a role in transporting and storing e-liquids in atomizers. According to Darcy’s law, the flow rate of porous media can be expressed as:

Q=(K/μ)*A*(Δp/L)

• Q is the flow rate through porous media, measured in m³/s.
• K is the permeability of porous media, measured in m². Permeability is an inherent property of porous substance, which characterizes the ability of liquids to pass through porous structures.
• It is only related to the material, pore size, and porosity of the porous substance, and is independent of the properties of the liquid itself.
• A is the cross-sectional area of seepage, measured in m³.
• Δp is the pressure difference between the cross-sections at both ends of the porous structure, measured in Pa.
• μ is the viscosity of the fluid, measured in Pa · s.
• L is the distance between the cross-sections at both ends of the porous structure, measured in m.

When standing still, the seepage flow rate Q changes very little; When the atomizer is working, the temperature of the e-liquid inside the cotton or ceramic will increase, and the μ viscosity of the e-liquid will decrease with the increase of temperature, resulting in an increase in the permeation flow rate Q within the same time period.
At the same time, the airflow velocity in the airway increases, causing a decrease in pressure on the atomization surface, resulting in an increase in Δp and a corresponding increase in the permeate flow rate Q. Therefore, the temperature and air flow velocity of e-liquid have a significant impact on the transport of e-liquid during the atomization process. In the case where the diameter of the atomization core is fixed, the flow velocity of air is mainly determined by the air flow rate entering the atomization core, so the size and position of the inlet hole are quite important for the atomization process.

Heat transfer pathway during vape vaporization process

The heating atomization method uses electric energy to drive the heating wire, which generates heat under the Joule effect, causing the atomization of e-liquid to produce aerosols. During the atomization process, the input heat is:
Q(input)=I²Rt

• I is the input current, measured in Α
• R is the resistance, measured in Ω
• t is time, measured in S.

The amount of heat that needs to be absorbed when the temperature of e-liquid rises from room temperature to the critical temperature before vaporization is:
Q=Cm*(T-T)

• Cm is Atomized e-liquid.
• T-T is Boiling temperature subtracts starting temperature
• C is the specific heat capacity of e-liquid, measured in (J/kg·°C).
• m is the mass, measured in kg.
• T is the temperature, measured in °C.

The heat absorbed by the vaporization of e-liquid is:
Q=r x m

• r is the latent heat of vaporization of e-liquid, measured in kJ/kg.
• m is Atomized e-liquid, measured in kg.

The effective heat during the entire atomization process is the heat absorbed by the heating and vaporization of the e-liquid, which is: Heating and heat absorption of e-liquid+vaporization and heat absorption of e-liquid.

The ineffective heat lost during the atomization process is: Heating heat of heating wire+heating heat of non atomized e-liquid and cotton+heating heat of pipe wall+heat of air replacement.

Therefore, the methods to improve atomization efficiency can start from two aspects: increasing effective heat and reducing ineffective heat.
