Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and in particular to a method for preparing an additive liquid for an atomizer, the additive liquid and an atomizer. Background Art

[0002] With the implementation of the new national standard, tobacco-flavored electronic atomizers have become the mainstream in China. However, due to the presence of tobacco extracts in the atomizer liquid, such products have problems such as core sticking and coking. In addition, there is also the problem of poor atomization performance of the atomizer liquid, making it difficult to achieve a large smoke volume and a large number of puffs (for example, >1000 puffs) puffing experience.

[0003] To address this problem, current research mainly uses some techniques to remove macromolecules (such as polysaccharides, proteins, starch, and pectin) from tobacco or tobacco extracts. This will result in the removal of aroma components along with macromolecules, resulting in excessive aroma loss. In addition, these methods do not completely solve the problems of wick sticking and coking, and cannot achieve a long-term smoking experience with large smoke volume and a large number of puffs.

[0004] Therefore, there is a strong demand for retaining the aroma while solving the problems of core sticking and coking. Summary of the invention

[0005] Accordingly, a first aspect of the present invention provides a method for preparing an additive liquid for an atomizer.

[0006] In some embodiments, the methods of the present invention include a step of removing cations.

[0007] Introducing a step to remove cations during the preparation of the additive liquid for the atomizer reduces the smoke attenuation rate, thereby improving the smoking experience; at the same time, it reduces the amount of fouling and solves the problem of easy core sticking and coking of the atomizer.

[0008] In some embodiments, the method of the present invention further comprises a step of removing anions to obtain a liquid having an electrical conductivity of less than 1000 μS / cm, preferably less than 500 μS / cm.

[0009] On the basis of removing cations, the step of removing anions is introduced in the process of preparing the additive liquid for the atomizer, which not only further reduces the smoke attenuation rate, but also additionally increases the atomization volume and further reduces the fouling volume, thereby further optimizing the smoking experience and reducing the chance of core sticking and coking.

[0010] In some embodiments, the cation is selected from one or more of manganese ions, iron ions, zinc ions, copper ions, potassium ions, magnesium ions, calcium ions, and sodium ions.

[0011] In some embodiments, the step of removing cations is performed using a cation exchange resin.

[0012] In some embodiments, the step of removing anions is performed using an anion exchange resin.

[0013] In some embodiments, the removing cations step and the removing anions step are accomplished using electrodialysis.

[0014] When electrodialysis treatment is introduced during the preparation of the additive liquid for the atomizer, compared with the ion exchange method, the method of some embodiments of the present invention further improves the atomization amount and further reduces the smoke attenuation rate, thereby providing excellent atomization performance and improving the suction experience; in addition, the amount of fouling is further reduced, thereby further reducing the probability of core sticking and coking. Without wishing to be bound by theory, the inventor believes that this is because the electrodialysis method not only removes cations and anions, but also removes organic acids and organic bases in the liquid. In addition, compared with the ion exchange method, the operating steps of the electrodialysis method are simpler and the processing efficiency is greatly improved; the electrodialysis method can maintain the taste of the atomized liquid.

[0015] In some embodiments, the voltage during electrodialysis is set to 1 V to 30 V; the current during electrodialysis is set to 0.05 A to 20 A; and the duration of electrodialysis is 0.1 hour to 24 hours.

[0016] In a preferred embodiment, the voltage during electrodialysis is set to 12V to 16V, the current is set to 5A to 10A; and the duration of electrodialysis is 1 to 4 hours.

[0017] By selecting the above parameters, the use of electrodialysis further increases the atomization volume and reduces the smoke attenuation rate, providing a better smoking experience.

[0018] In some embodiments, before or after the removing step, the method further comprises the step of adding an atomized solvent and / or a fragrance.

[0019] In some embodiments, before the removal step, the method further includes the step of diluting the object to be treated with water to obtain a diluted liquid with a viscosity of 1cp to 100cp, and after the removal step, the method further includes the step of removing water. The present invention does not limit the dilution multiple, as long as the removal step can be performed after dilution. For example, in some embodiments, dilution is performed by adding water with a volume greater than or equal to 0 times and less than or equal to 20 times the volume of the object to be treated. In a preferred embodiment, dilution is performed by adding water with a volume greater than 0 and less than or equal to 10 times the volume of the object to be treated. In this dilution, not only the viscosity of the liquid is moderate, which is convenient for the removal of cations and / or anions, but also the step of removing water avoids the need to remove a large amount of water, shortens the dewatering time, and improves the efficiency of dewatering.

[0020] The second aspect of the present invention provides an additive liquid for an atomizer prepared by the method of the present invention.

[0021] The third aspect of the present invention provides an atomizer, comprising a liquid storage tank, an atomizing assembly and the additive liquid of the present invention. The liquid storage tank is used to contain the additive liquid of the atomizer. The atomizing assembly is used to make the additive liquid of the atomizer form an aerosol. The atomizing assembly is in fluid communication with the liquid storage tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0027] Throughout the specification, unless otherwise specifically stated, the terms used herein should be understood as meanings commonly used in the art. Therefore, unless otherwise defined, all technical and scientific terms used herein have the same meanings as those generally understood by those skilled in the art. In the event of a conflict, this specification takes precedence.

[0028] It should be noted that in the present disclosure, the term "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a method or device including a series of elements includes not only the elements explicitly stated, but also other elements not explicitly listed, or also includes elements inherent to the implementation of the method or device. In the absence of further restrictions, an element defined by the sentence "comprising..." does not exclude the presence of other related elements in the method or device including the element.

[0029] At present, tobacco-flavored electronic atomization devices have become mainstream. The atomizing liquid added to the atomization device contains tobacco extracts, which will cause such products to often have problems such as core sticking and coking, and cause the atomization performance (for example, large smoke volume, large number of puffs) to decrease, which in turn seriously affects the smoking experience.

[0030] To solve this problem, some researchers use solvent extraction, column chromatography, enzymatic hydrolysis, supercritical extraction, molecular distillation and other methods to reduce the content of macromolecules. However, these methods remove the aroma components (such as esters and ketones) together with the macromolecules, resulting in excessive aroma loss; at the same time, these methods also fail to solve the problems of core sticking and coking, and cannot achieve a long-term smoking experience with large smoke volume and a large number of puffs.

[0031] Both core sticking and coking are caused by excessive fouling of the atomized aerosol in the atomizer. The inventors of the present invention unexpectedly discovered that the cations in the additive liquid of the atomizer play a relatively important role in the generation of fouling.

[0032] To this end, the present invention provides a method for preparing an additive liquid for an atomizer. The method includes a step of removing cations in the liquid. The method not only retains the aroma components, but also solves the problems of core sticking and coking.

[0033] As used herein, "additive liquid for atomizer" or "additive liquid" refers to a liquid used to be added to an electronic atomizer so as to provide the user with a puffing and puffing experience. The additive liquid for atomizer may be in the form of oil or liquid. The additive liquid for atomizer is prepared, for example, from tobacco extract. Exemplary additive liquids may contain nicotine, flavors, and atomizing solvents, etc.

[0034] In the method of the present invention, the object to be processed for the removal step can be a raw material for the atomizing liquid used for the atomizer, i.e., a tobacco extract, which contains a component that provides a suction experience to the user. Exemplarily, the tobacco extract can be a liquid, a paste, a solid, such as a freeze-dried form. The object to be processed can also be a product to which other ingredients (such as flavors, atomizing solvents, etc.) or further processed are further added on the basis of the tobacco extract. For example, the object to be processed can also be an atomizing liquid that can be used immediately (can be added to an atomizer for use) prepared from a tobacco extract, such as a commercially available atomizing liquid.

[0035] In fact, currently, most studies in this field believe that the above-mentioned biomacromolecules in the additive liquid of the atomizer are the main cause of atomizer fouling, while there are no reports on the use of ion exchange method to remove ions in the additive liquid of the atomizer to reduce atomizer fouling, core sticking and / or coking.

[0036] In some embodiments, the methods of the present invention do not comprise a step of removing macromolecules (eg, polysaccharides, proteins, starches, and / or pectins).

[0037] In some embodiments, the step of removing cations is performed using a cation exchange resin. The present invention does not limit the type of cations removed by the ion exchange method, which depends on the object to be treated. In some embodiments, the cations of the present invention refer to inorganic cations. For example, when treating commercial atomized liquid, the cations removed can be one or more of manganese ions, iron ions, zinc ions, copper ions, potassium ions, magnesium ions, calcium ions and sodium ions. The present invention does not limit the type of cation exchange resin, as long as it can exchange cations in the liquid phase. Exemplarily, the cation exchange resin can be a cation exchange resin T-42h. For the mass ratio of the liquid to be treated to the cation exchange resin, the present invention has no particular restrictions, and an exemplary mass ratio is less than or equal to 10 / 1, such as 10 / 1, 4 / 1 and 1 / 2.

[0038] In some embodiments, the method of the present invention further comprises the step of removing anions in the liquid. In some embodiments, the step of removing anions is performed by using an anion exchange resin. In some embodiments, the anions of the present invention refer to inorganic anions. The present invention does not limit the type of anions removed by the ion exchange method, which depends on the object to be treated. For example, when treating commercial atomized liquid, the removed anions can be one or more of fluoride ions, chloride ions, nitrite ions, bromide ions, nitrate ions, sulfate ions, phosphate ions, etc. The present invention does not limit the type of anion exchange resin, as long as the anions in the liquid phase can be exchanged. Exemplarily, the model of the anion exchange resin can be D201. For the mass ratio of the liquid to be treated to the anion exchange resin, the present invention has no particular restrictions, and the exemplary mass ratio is less than or equal to 10 / 1, for example, 10 / 1, 4 / 1 and 1 / 2.

[0039] In some embodiments, the step of removing cations may be performed before the step of removing anions. For example, the step of removing cations includes: adding a cation exchange resin with a mass of 1 / 10 to 2 / 1 of the mass of the liquid, stirring, and filtering to obtain a supernatant. Next, the step of removing anions includes: taking the above-mentioned supernatant; and adding an anion exchange resin with a mass of 1 / 10 to 2 / 1 of the mass of the supernatant taken, stirring, and filtering. Stirring and filtering can be performed, for example, by stirring at a speed of 120 rpm at room temperature for 4 hours and filtering.

[0040] In other embodiments, the step of removing cations may be performed after the step of removing anions.

[0041] The present invention has no particular limitation on the treatment time when using ion exchange resin, as long as most of the corresponding ions can be removed.

[0042] In some embodiments, when the object to be treated is the raw material of the atomized liquid, for example, tobacco extract, after removing the cations and / or anions, the product of the removal step can be compounded with substances such as atomizing solvents and / or flavors to prepare an additive liquid.

[0043] In other embodiments, the method for preparing an additive liquid for an atomizer of the present invention comprises:

[0044] obtaining a tobacco extract; and

[0045] Electrodialysis treatment is used to obtain a liquid with an electrical conductivity of 1000 μS / cm or less.

[0046] The present invention does not limit the equipment used for electrodialysis. Exemplarily, the equipment used for electrodialysis may be a CR-DTM homogeneous membrane electrodialyzer.

[0047] The electrical conductivity of the liquid treated by the method of the present invention can be, for example, less than or equal to 800 μS / cm, less than or equal to 600 μS / cm, less than or equal to 500 μS / cm, less than or equal to 400 μS / cm, less than or equal to 300 μS / cm, less than or equal to 200 μS / cm, less than or equal to 100 μS / cm, less than or equal to 50 μS / cm, less than or equal to 40 μS / cm and less than or equal to 30 μS / cm.

[0048] The voltage when using electrodialysis in the method of the present invention can be, for example, 1V to 30V, for example, 2V, 3V, 4V, 5V, 6V, 7V, 8V, 9V, 10V, 11V, 12V, 13V, 14V, 15V, 16V, 17V, 18V, 19V, 20V, 21V, 22V, 23V, 24V, 25V, 26V, 27V, 28V, 29V and 30V.

[0049] The current when using electrodialysis in the method of the present invention can be, for example, 0.05A to 20A, for example, 0.05A, 0.1A, 0.5A, 1A, 2A, 3A, 4A, 5A, 6A, 7A, 8A, 9A, 10A, 11A, 12A, 13A, 14A, 15A, 16A, 17A, 18A, 19A and 20A.

[0050] The duration of the method of the present invention when using electrodialysis can be, for example, greater than 0.1 hours, for example greater than 0.2 hours, greater than 0.5 hours, greater than 1 hour, greater than 2 hours, greater than 3 hours, greater than 4 hours, greater than 6 hours, greater than 8 hours, greater than 10 hours, greater than 12 hours and greater than 24 hours.

[0051] In some embodiments, the method of the present invention further comprises the step of compounding the tobacco extract with atomizing solvents and / or flavors and other substances. Exemplarily, the compounding step is performed before electrodialysis.

[0052] In some embodiments, optionally, before the step of removing cations or before electrodialysis, the method of the present invention also includes the step of diluting the liquid with water, wherein the viscosity of the diluted liquid is 1cp to 100cp. Dilution reduces the viscosity of the liquid, making it convenient to add cation exchange resin (optionally, and anion exchange resin); or, increasing the fluidity of the liquid, making it easy to perform electrodialysis cycles. Dilution with water can impart or strengthen a medium environment in which ions can migrate. Exemplarily, in some embodiments, the volume of the added liquid is greater than 0.1 times and less than or equal to 20 times of water for dilution. In a preferred embodiment, the volume of the treated object is greater than 0 and less than or equal to 10 times of water for dilution. In this dilution, not only is the viscosity of the liquid moderate, which is convenient for the removal of cations and / or anions, but also avoids the need to remove a large amount of water in the step of removing water, shortens the dehydration time, and improves the efficiency of dehydration. In a specific embodiment, deionized water is used for dilution. Deionized water can be used without introducing a large amount of ions while diluting.

[0053] In some embodiments, after the step of removing cations or after electrodialysis, the method of the present invention further comprises a step of removing water. In some preferred embodiments, the step of removing water is after the step of removing anions or after electrodialysis. Removing water can increase the concentration of the additive liquid, avoiding affecting the suction experience when using the additive liquid to prepare the atomized liquid or using the additive liquid as the atomized liquid. Exemplarily, water can be removed by rotary evaporation or freeze drying.

[0054] The present invention also provides an additive liquid for an atomizer, which is prepared by the method of the present invention. Such an additive liquid at least removes most of the inorganic cations, for example, 50%, 60%, 70%, 80%, 90%, 95%, 96%, 97%, 99% of the inorganic cations are removed. Preferably, most of the inorganic anions are also removed, for example, 50%, 60%, 70%, 80%, 90%, 95%, 96%, 97%, 99% of the inorganic anions are removed. More preferably, most of the organic acids and organic bases are also removed, for example, 50%, 60%, 70%, 80%, 90%, 95%, 96%, 97%, 99% of the organic acids and organic bases are removed. Not only the aroma-causing components are retained, but also the problems of core sticking and coking are solved.

[0055] The present invention also provides an atomizer, comprising a liquid storage tank, an atomizing assembly and the additive liquid of the present invention, wherein the liquid storage tank is used to contain the additive liquid, and the atomizing assembly is connected to the liquid storage tank in fluid communication and is used to make the additive liquid form an aerosol.

[0056] The present invention also provides an atomization device, comprising the above-mentioned atomizer and a battery assembly. The battery assembly is used to supply power to the atomizer.

[0057] The invention also provides a use of an atomizer additive liquid for improving fouling, core sticking and / or coking of an atomizer.

[0058] The present invention also provides the use of the atomizer additive liquid of the present invention in improving the fouling, core sticking and / or coking of the atomizer.

[0184] Test Example 3: Test of atomization volume and attenuation rate

[0185] The above-mentioned atomized liquids were respectively loaded into an atomizer equipped with a battery with a power of 6.5W, and 1200 puffs were drawn to test the atomization amount (mg / puff) and the smoke attenuation rate (%) (atomization amount: the mass of the atomized aerosol per puff of the electronic atomization device; attenuation rate: the attenuation of the average atomization amount of the first 50 puffs of the electronic atomization device compared with the average atomization amount of the last 50 puffs). Among them, the atomization amount and smoke attenuation rate of the atomized liquid before treatment and the atomized liquid after treatment according to Examples 1 to 7 and Examples 9 to 12 are shown in Tables 25 to 29 and Tables 31 to 34 below, and the atomization amount and smoke attenuation rate of the atomized liquid containing the tobacco extract before treatment and the atomized liquid containing the tobacco extract after treatment according to Example 8 are shown in Table 30.

[0187] XLY atomizing liquid Atomization volume (mg / puff) Smoke attenuation rate (%) Before treatment 6.74. 18.91％ After treatment 7.14 7.84％

[0188] As shown in Table 25, the ion exchange method has no significant effect on the atomization amount, and the smoke attenuation rate drops from 18.91% to 7.84%, a decrease of about 60%.

[0189] Table 26 Atomization volume and smoke attenuation rate of ZBY atomized liquid, DFY atomized liquid and NB2 atomized liquid before treatment and ZBY atomized liquid, DFY atomized liquid and NB2 atomized liquid after treatment according to Examples 2 to 4

[0190]

[0191]

[0192] As shown in Table 26, the use of electrodialysis not only increases the atomization amount by about 30%, but also reduces the smoke attenuation rate by about 70%.

[0197] It can be seen from Tables 27 and 28 that adjusting the parameters during electrodialysis (voltage, current and cycle time) can still improve the atomization amount and smoke attenuation rate of the ZBY atomized liquid.

[0202] It can be seen from Table 30 that, compared with the atomizing liquid to which 1 wt % untreated tobacco extract is added, the atomizing amount of the atomizing liquid to which 1 wt % treated tobacco extract is added is increased by about 35%, and the smoke attenuation rate is reduced by about 75%.

[0212] Combined with Table 26, compared with the ZBY atomized liquid treated by the ion exchange method according to Example 12, the ZBY atomized liquid treated by the electrodialysis method according to Example 2 has a larger atomization amount and a higher degree of improvement in the smoke attenuation rate.

[0213] Test Example 4: Fouling Test

[0214] The XLY atomized liquid before treatment and the XLY atomized liquid after treatment according to Examples 1 and 9 were respectively loaded into an atomizer equipped with a 6.5W power battery, and 1200 puffs were drawn. The atomizer core was taken out, cut open and photographed. The results are as follows: Figure 1 As shown. Figure 1 It can be seen that compared with the XLY atomized liquid before treatment, the XLY atomized liquid treated with the cation exchange resin according to Example 9 has less fouling in the electronic atomization device; and compared with the XLY atomized liquid treated only with the cation exchange resin according to Example 9, the XLY atomized liquid treated with the cation exchange resin and the anion exchange resin according to Example 1 has more reduced fouling in the electronic atomization device.

[0215] The ZBY atomized liquid before treatment and the ZBY atomized liquid after treatment according to Example 2 and Example 12 were respectively loaded into an atomizer equipped with a 6.5W power battery, and 1600 puffs were drawn. The atomized cores were taken out, cut open and photographed. The results are as follows: Figure 2 As shown. Figure 2 It can be seen that compared with the ZBY atomized liquid before treatment, the ZBY atomized liquid treated by the ion exchange method according to Example 12 has less scaling in the atomization device; and compared with the ZBY atomized liquid treated by the ion exchange method according to Example 12, the ZBY atomized liquid treated by the electrodialysis method according to Example 2 has more scaling reduction in the electronic atomization device.

[0216] The DFY atomized liquid before treatment and the DFY atomized liquid after treatment according to Example 3 were respectively loaded into an atomizer equipped with a 6.5W power battery, and 1600 puffs were drawn on each of them. The atomizer cores were taken out, cut open and photographed. The results are as follows: Figure 3 The NB2 atomized liquid before treatment and the NB2 atomized liquid after treatment according to Example 4 were respectively loaded into an atomizer equipped with a 6.5W power battery, and 1200 puffs were drawn on each. The atomizer cores were taken out, cut open, and photographed. The results are shown in FIG. Figure 4 As shown. Figure 2 , Figure 3 and Figure 4 It can be seen that for atomized liquid with different amounts of fouling in the electronic atomization device, electrodialysis treatment can significantly reduce fouling.

[0217] Test Example 5 Sensory Tasting Test

[0218] 20 people tasted the ZBY atomized liquid before treatment, the DFY atomized liquid before treatment, the NB2 atomized liquid before treatment, and the ZBY atomized liquid, DFY atomized liquid, and NB2 atomized liquid after treatment according to Examples 2 to 4, and the sensory taste results are as follows. 19 people believed that there was no difference between the ZBY atomized liquid treated according to Example 2 and the ZBY atomized liquid before treatment. 18 people believed that there was no difference between the DFY atomized liquid treated according to Example 3 and the DFY atomized liquid before treatment. 19 people believed that there was no difference between the NB2 atomized liquid treated according to Example 4 and the DFY atomized liquid before treatment.

[0219] The same 20 people smoked the ZBY atomized liquid before treatment and the ZBY atomized liquid after treatment according to Example 12, and the results were as follows. Compared with the ZBY atomized liquid before treatment, 11 people thought that there was no difference in the ZBY atomized liquid after treatment according to Example 12, and 9 people thought that the smoke of the ZBY atomized liquid after treatment according to Example 12 was softer and the sourness was enhanced.

[0220] From the above tasting results, it can be seen that compared with the ZBY atomized liquid treated by the ion exchange method according to Example 12, the taste of the ZBY atomized liquid treated by the electrodialysis method according to Example 2 is basically unchanged, that is, the electrodialysis method can maintain the taste of the atomized liquid, which may be related to the fact that the pH of the system has not changed significantly.

[0221] In summary, the method for preparing the additive liquid for the atomizer of the present invention can help to achieve a long-term smoking experience with a large amount of smoke and a large number of puffs, and can also avoid the problem of core sticking or coking in the electronic atomization device during its service life.
