The present disclosure relates to the field of atomization, and particularly to a water-based atomizing agent, a water-based atomizing substance for a specified purpose, a cartomizer, and an atomizing device.
With the rapid development of the field of electronic atomization in recent years and the gradually expanded cognition of the electronic atomizing device of people, the market supervision and regulations in the field of electronic atomization under the national legal system are becoming stricter. Under this background, it is urgent to further innovate and develop an atomizing liquid that is less harmful to the human body, can bring better taste experience, and complies with laws and regulations and supervision requirements.
There is usually no water in a traditional atomizing liquid, which is mainly because the atomizing liquid containing water is difficult to produce sufficient smoke for a user to inhale, and the water is easy to leak out of an atomizer storing the atomizing liquid due to a low viscosity, resulting in liquid leakage. However, the atomizing liquid rich in water has a lower viscosity than the traditional atomizing liquid, and a required atomization temperature can be lower, so that the user may have a more comfortable and refreshing taste, and there are less harmful substances produced during atomization.
It is known that an atomizing liquid containing water and sugar alcohol has been developed, which can produce smoke for human to inhale after being heated at a certain temperature. However, further research has found that the atomizing liquid containing water and sugar alcohol has a poor fluidity after being mixed and heated, E-liquid shortage is easy to occur around a heating assembly of the atomizer, scorching is easy to occur during heating, sometimes failing to produce sufficient smoke and affecting the taste experience of the user due to the scorching.

It can be seen from the technical solutions above that the present disclosure has the following advantages:
The present disclosure provides a water-based atomizing agent, a water-based atomizing substance for a specified purpose, a cartomizer, and an atomizing device, which can produce smoke with refreshing taste, sufficient smoke volume, and less harm to human, thus reducing the production of harmful substances in the smoke and improving the taste experience of the smoker.
In an embodiment of the present disclosure, the ingredients of the water-based atomizing agent comprise a mixed matrix and an active agent used for improving a surface activity of the mixed matrix. The mixed matrix is capable of producing smoke under certain conditions. For example, the mixed matrix may be heated and produce smoke under an environmental condition that the water-based atomizing agent is heated to a certain temperature, or the mixed matrix may produce smoke when the water-based atomizing agent is subjected to high-frequency vibration such as ultrasonic waves. For certain conditions for producing the smoke, they are not limited herein.
Since the water-based atomizing agent comprises the mixed matrix capable of producing smoke and the active agent capable of improving the surface activity of the mixed matrix and improving the fluidity of the mixed matrix, sufficient atomizing liquid can be continuously supplied around the atomizing assembly of the atomizer. The water-based atomizing agent can produce sufficient smoke under conditions such as heating or vibration for a user to inhale, and due to a high water content in the water-based atomizing agent, the taste of the smoke is refreshing, thus improving the taste of the smoke or the therapeutic effect of the water-based atomizing agent on a human after the water-based atomizing agent enters the human body.
In the embodiment of the present disclosure, a mass percentage of the active agent in the water-based atomizing agent may be 0.01% to 20%.
It should be noted that, the active agent may be at least one selected from the group consisting of phenethyl alcohol, ethyl lactate, ethyl acetate, and ethanol, which is not specifically limited herein. Preferably, the active agent may be ethanol.
Preferably, the mass percentage of the active agent in the water-based atomizing agent may be 0.05% to 15%.
Preferably, the mass percentage of the active agent in the water-based atomizing agent may be 0.1% to 10%.
Preferably, the mass percentage of the active agent in the water-based atomizing agent may be 0.2% to 5%.
Preferably, the mass percentage of the active agent in the water-based atomizing agent may be 0.5% to 3%.
Preferably, the mass percentage of the active agent in the water-based atomizing agent may be 1% to 2%.
In the embodiment of the present disclosure, the mixed matrix may comprise:
It should be noted that, the water matrix is used for producing smoke and dissolving an essence and other substances, and the alcohol matrix is used for dissolving an essence, preventing corrosion, and inhibiting coagulation.
It should be noted that, the alcohol matrix may comprise at least one of propylene glycol and glycerol, which is not specifically limited herein. In the embodiment of the present disclosure, the water matrix may comprise:
It should be noted that, sugar alcohol may be at least one selected form the group consisting of erythritol, xylitol, mannitol, and sorbitol; and preferably, sugar alcohol is xylitol.
Further, the surface tension of the active agent is smaller than that of water. In the embodiment of the present disclosure, if there is no active agent in the water-based atomizing agent, when the water content of the water-based atomizing agent is high, the mixed matrix used for producing smoke is wrapped by water therein due to the large surface tension of the water, so that the water-based atomizing agent is difficult to quickly flow to the heating assembly or the ultrasonic assembly of the atomizer, resulting in incapability of continuously obtaining sufficient water-based atomizing agent to produce smoke when the heating assembly heats and atomizes the water-based atomizing agent or the ultrasonic assembly vibrates and atomizes the water-based atomizing agent, which easily leads to E-liquid shortage of the heating assembly or the ultrasonic assembly during atomization of the water-based atomizing agent. Therefore, scorching occurs during atomization, which not only affects the taste of the smoke or the therapeutic effect of the smoke, but also easily damages atomization equipment and shortens a service life of the atomization equipment. Therefore, in the embodiment of the present disclosure, since the active agent such as ethanol is added in the water-based atomizing agent, and the surface tension of the active agent such as ethanol is far smaller than that of the water, the overall surface tension of the water-based atomizing agent is reduced. The mixed matrix can flow more easily and quickly to the periphery of the heating assembly or the ultrasonic assembly due to the reduced surface tension, so that E-liquid shortage is not easy to occur around the heating assembly or the ultrasonic assembly. In this way, when the water-based atomizing agent produces smoke, the scorching is greatly reduced or even eliminated during atomization, thus improving the taste of the smoke and the therapeutic effect of the smoke, ensuring that the atomization equipment is not easily damaged, and prolonging a service life of the atomization equipment for atomizing the water-based atomizing agent.
Further, the surface tension of the active agent is smaller than that of the mixed matrix.
It should be noted that, the mixed matrix may be a fully mixed matrix of water and xylitol, or a fully mixed matrix of water and other sugar alcohols. However, in the embodiment of the present disclosure, the fully mixed matrix of water and xylitol can produce a lot of smoke during atomization, and the experimental result shows that the smoke volume produced by the fully mixed matrix of water and xylitol is obviously more than that of the fully mixed matrix of water and other sugar alcohols.
In addition, the water-based atomizing agent in the embodiment of the present disclosure may be in a liquid state, a semi-solid state, or a solid state, which is not specifically limited herein.
In the embodiment of the present disclosure, the surface tension of the active agent such as the ethanol is smaller than that of the mixed matrix of water and xylitol mixed fully, which can ensure that the water-based atomizing agent fully, quickly, and smoothly flows to the periphery of the heating assembly or the ultrasonic assembly, thus being fully atomized during atomization.
It should be noted that, the water-based atomizing agent in the embodiment of the present disclosure may be E-liquid used in the atomizing device. Moreover, the E-liquid rich in water is usually called water-based E-liquid in the atomizing device industry. The water-based atomizing agent in the embodiment of the present disclosure may also be a medical water-based atomizing agent used in a medical field, which is not specifically limited herein.
In the embodiment of the present disclosure, if water is used as a part of the E-liquid, when a user inhales the E-liquid containing water, the water has the characteristics of removing a foreign flavor, reducing residual E-liquid substances in mouth of the user, providing a purer taste, lowering an atomization temperature and reducing a viscosity. Moreover, since the water has a low viscosity, the viscosity of the E-liquid added with the water is also reduced, so that the user may get more refreshing and less sticky taste experience when inhaling. In addition, the E-liquid containing water can produce smoke by low-temperature heating, which can further reduce the production of harmful substances, and is beneficial for the health of the user, thus realizing a wider application range of this E-liquid in a future electronic atomization field.
The water-based atomizing agent of the embodiment of the present disclosure, and test results and technical effects thereof are described in detail hereinafter through experiments on the water-based atomizing agent containing different mass ratios of ingredients.
It should be noted that, measurement results of harmful substances of various ingredients in the water-based atomizing agent, and experimental results of surface tension and smoke volume of various embodiments will be described in detail in the after-mentioned Table 1 to Table 3.

In Embodiment 1 to Embodiment 23 above, since propylene glycol has solvent properties, such as the ability to dissolve a spice in E-liquid, when propylene glycol is added in the E-liquid containing xylitol and water, it can provide a throat hit sensation for the user and has sterilization effect. Therefore, propylene glycol is added in the E-liquid containing water and xylitol.
In Embodiment 1 to Embodiment 23 above, assuming that the water-based atomizing agent is heated by a heating assembly, after water and xylitol are mixed, since water has a relatively large surface tension, the water-based atomizing agent containing water and xylitol may be subjected to resistance of the surface tension of the water, so that it is difficult to heat and atomize the water-based atomizing agent containing water and xylitol by the heating assembly.
However, the surface tension of the water is reduced due to the addition of other substances, so as to reduce the resistance to the water-based atomizing agent flowing to the atomizing core, so that the water-based atomizing agent can flow more quickly and smoothly to the heating assembly, then the heating assembly can more quickly heat and atomize a large amount of water-based atomizing agent containing water and xylitol, thus improving the flowing speed of the water-based atomizing agent flowing to the heating assembly and increasing the production of smoke volume.
It was found that when ethanol was added in the water-based atomizing agent containing water and xylitol, the surface tension of the water could be greatly reduced, so that the heating assembly could fully heat and atomize the E-liquid to produce sufficient smoke volume for the user to inhale.
Further, in the embodiments of the present disclosure, in order to fully dissolve various substances such as the spice in the water-based atomizing agent while reducing the surface tension of the water in the water-based atomizing agent, propylene glycol and ethanol are added in the mixture of xylitol and water.
Further, in the embodiments of the present disclosure, in order to make the water-based atomizing agent produce more smoke during atomization, the alcohol matrix such as glycerol may be added in the water-based atomizing agent.
Tests of the harmful substances, surface tension, and smoke volume of the water-based atomizing agent in Embodiment 1 to Embodiment 23 will be further described.
According to the newly published national standard GB/T 9733-2008 for atomizing devices, amounts of formaldehyde, acetaldehyde, acrolein, and 2,3-butanedione released in each inhalation of E-liquid were investigated to evaluate the safety of the E-liquid.
Samples selected for experiment were: propylene glycol, glycerol, a blank atomizing agent comprising propylene glycol and glycerol with a mass ratio of 79:21, a control sample 1 comprising propylene glycol and glycerol with a mass ratio of 5:5, a control sample 2 comprising propylene glycol and glycerol with a mass ratio of 4:6, and samples obtained in Embodiment 1 to Embodiment 23.
2.1) Testing steps of linear smoking machine: the samples as listed above were respectively dripped into an atomizing device provided with an open Rebuildable Dripping Atomizer (RDA), and a heating body, and a E-liquid guide body adapted to different water-based atomizing agents were adjusted according to different surface tensions of various water-based atomizing agents in Embodiment 1 to Embodiment 23 above. Inhalation was carried out by the linear smoking machine (model: SM450) according to a bell-shaped curve, and when puffing, an external constant voltage power supply of the atomizing device was 4.5 V. A puff profile of the inhalation mechanism was a square wave curve, wherein a puff volume was 55 mL, a puff duration was 3 seconds per inhalation with an interval of 30 seconds, and there were 30 inhalations. The smoke volume was captured with two 45 mm Cambridge glass fiber filters (containing an aldehyde ketone derivatization reagent).
2.2) High-performance liquid chromatography test: the contents of major carbonyl compounds in a captured substance were tested by using an industrial standard method of “Cigarettes Determination of major carbonyls in mainstream cigarette smoke”.
2.3) Synchronization steps of atomizing device with smoking machine: a traditional atomizer (resistance wire+E-liquid guide cotton) was synchronized with the smoking machine by using a regulated power supply module (with a maximum voltage of 6.2 V and a test voltage of 4 V).
Test results were as follows:
Data of embodiments in which the mass ratio of glycerol to propylene glycol was 50:50 and the mass ratio of xylitol to water was 40:60 are shown in Table 2.
The detection method of the carbonyl compounds in Table 1 was international GB/T 9733-2008.
It can be seen from the data in Table 1 and Table 2 that, in Embodiment 1 to Embodiment 23 in which there were certain weight ratios of water and xylitol in a total solution, contents of main harmful substances such as formaldehyde, acetaldehyde, acrolein, and 2,3-butanedione, are all far lower than those of formaldehyde, acetaldehyde, acrolein, and 2,3-butanedione in the control sample 1 and the control sample 2. Moreover, Table 2 more intuitively shows that, with the increase of water content to a certain proportion, release amounts of the hydroxyl compounds have been reduced below testing thresholds of the testing equipment. This is because the water-based atomizing agent in the embodiments of the present disclosure contains water and xylitol, and water has a low boiling point, the atomization temperature of the water-based atomizing agent can be greatly reduced. However, the harmful substances are usually produced after the water-based atomizing agent is heated at a high temperature, and hardly produced under low-temperature heating, or ultrasonic vibration of the ultrasonic atomizing assembly under normal-temperature or low-temperature. Even if the harmful substances are produced, the contents of the harmful substances produced may be very low under the low-temperature heating, or ultrasonic vibration of the ultrasonic atomizing assembly under normal-temperature or low-temperature.
Therefore, based on the aforementioned embodiments and the experimental analysis of harmful substances, it is evident that the E-liquid containing water, especially the E-liquid rich in water, is much safer for human use compared with E-liquid used in conventional atomizing devices currently available on the market. The E-liquid containing water should be researched and developed to be more widely used in the field of electronic atomization.
The samples of Embodiment 1 to Embodiment 23 were selected for comparison with the blank atomizing agent, and surface tensions of the atomizing agents at normal temperature and normal pressure were determined, respectively.
The detection method of the surface tensions in Table 3 was national standard: GB/T 5549-2010.
According to the data in Table 3, the water-based atomizing agent with a high water content has higher surface tension compared to blank atomizing agents. This can lead to slower flow rates of the water-based atomizing agent flowing to the atomizing core, thus increasing the airflow resistance in the airway of the atomizing devices. However, by adding the active agent such as ethanol that can reduce surface tension, the surface tension of the water-based atomizing agent rich in water may be adjusted to an appropriate range, so that the water-based atomizing agent can flow more smoothly and E-liquid shortage around the heating body can be greatly reduced, thus enabling the production of more smoke and facilitating the industrial design and production of suitable atomizing devices.
According to the data in Table 3, data of embodiments in which the mass ratio of glycerol to propylene glycol was 50:50, and the mass ratio of xylitol to water was 10:90 were compiled as shown in Table 4.
For convenience of understanding, please refer to
In order to verify that the xylitol produces a more noticeable amount of smoke in samples with high water content, representative Embodiment 1 to Embodiment 23 and the blank atomizing agent were selected for measurement. Test results of Embodiment 1 to Embodiment 23 and the blank atomizing agent were respectively analyzed independently, considering an interaction of different ingredients in the E-liquid.
2.1 Testing steps of linear smoking machine: the samples of Embodiment 1 to Embodiment 23 were respectively dripped into an atomizing device provided with an open Rebuildable Dripping Atomizer (RDA), the heating body and a E-liquid guide body in different atomizing cores were adjusted for adaption according to different surface tensions of the E-liquid in various embodiments, and inhalation was carried out by the linear smoking machine (model: SM450) according to a bell-shaped curve. During inhalation, the atomizing device was connected to an external constant voltage power supply at 4.5 V A puff profile of the inhalation mechanism was a square wave curve, wherein an inhalation capacity was 55 mL, a puff duration was 3 seconds per inhalation with an interval of 30 seconds, and there were 30 inhalations, and an average value was calculated. The mass of the atomizing device at an initial stage was weighed by a precision electronic balance, and the mass of smoke volume was characterized according to the weight loss of the atomizing device during inhalation.
The test results are shown in the following Table 5.
The total particulate matters in Table 5 above are the smoke volume in the embodiments of the present disclosure, and the total particulate matters are a proper term used to express the smoke volume in experiments in the field of atomization. According to the data in Table 5, in Embodiment 1, the smoke volume is increased obviously with the increase of the proportion of xylitol. Embodiments 15-23 are all superior to the blank atomizing agent in comparison.
As can be clearly seen from Table 5, the addition of xylitol into the water-based atomizing agent rich in water can greatly increase the smoke volume, playing a very significant role in smoke generation.
According to the data in Table 5, the results of the scheme that the mass ratio of glycerol to propylene glycol was 50:50 and the mass ratio of xylitol to water was 50:50 were arranged and shown in Table 6.
According to the data in Table 6, the results of the embodiments, in which the mass ratio of glycerol to propylene glycol was 50:50, the mass ratio of xylitol to water was 40:60, and ratios of the mixture of xylitol and water to the mixture of glycerol and propylene glycol were different, were compiled as shown in Table 7.
It can be intuitively seen from Table 6 that, under the same conditions, a total number of particles shows an increasing trend when the proportion of the sugar alcohol in the water matrix is larger. It can be clearly found from Table 7 that, the total number of particles also shows the increasing trend when the proportion of the mixture of xylitol and water in the water matrix is increased. Compared with Embodiment 3 with a high water content, the proportion of the xylitol is small, and data of the total number of particles is at a very low level, thus it can be seen that the water matrix comprising the sugar alcohol such as xylitol plays a decisive role in atomization effect of a water-based atomizing substance.
