Description

Technical Field

[0001] This application belongs to the field of electronic atomization technology, and particularly relates to an atomizing liquid, a compartmentalized atomizer, and an electronic atomization device. Background Technology

[0002] Electronic atomizers typically contain a rich variety of flavorings and fragrances dissolved in the emulsion, resulting in a diverse range of flavors and distinct tastes. These flavoring substances can vary significantly in polarity, often requiring some low-polarity flavorings to achieve a highly immersive and intense flavor. However, these substances are often difficult to dissolve in solvents containing large amounts of ethylene glycol and glycerol, leading to stratification between the low-polarity flavorings and the solvent. This can result in inconsistent tastes or even a burnt sensation during inhalation. Furthermore, ethylene glycol and glycerol are usually the primary sources of sufficient vapor production. Replacing them with solvents like propylene glycol or ethanol significantly reduces vapor production.

[0003] Therefore, it is necessary to provide an improved atomizing fluid. Summary of the Invention

[0004] In view of this, the main objective of this disclosure is to provide an atomizing liquid that can uniformly dissolve sufficient low-polarity aroma substances, resulting in an improved and consistent flavor after atomization without burning, while also providing a sufficient amount of vapor. A further objective of this application is to provide an atomizer and an electronic atomization device comprising the aforementioned atomizing liquid.

[0017] In addition to the technical problems solved by this disclosure, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions as described above, other technical problems that this disclosure can solve, other technical features contained in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the following specific embodiments. Detailed Implementation

[0018] The technical solution of this disclosure will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Throughout this specification, unless otherwise specified, the terminology used herein shall be understood as having the meaning as commonly used in the art. Therefore, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. In the event of any conflict, this specification shall prevail.

[0020] It should be noted that, in this disclosure, the term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, such that a method or apparatus that comprises a list of elements includes not only the elements expressly stated, but also other elements not expressly listed, or elements inherent to implementing the method or apparatus. Without further limitations, an element defined by the phrase "containing..." does not exclude the presence of other related elements in the method or apparatus that includes that element.

[0021] Unless otherwise stated, all percentages or % in this disclosure refer to percentages or mass percentages.

[0022] It should be understood that the phrases "one embodiment" or "some embodiments" used throughout the specification mean that a particular feature, structure, or characteristic related to an embodiment is included in at least one embodiment of this disclosure. Therefore, "in one embodiment" or "in some embodiments" appearing throughout the specification do not necessarily refer to the same embodiment.

[0023] Low-polarity flavor compounds, such as pinene, limonene, myrcene, caryophyllene, nonanal, decanal, lauryl alcohol, gamma-undecyl lactone, and rose ether, or natural extracts containing large amounts of low-polarity flavor compounds, such as sweet orange oil, bitter almond oil, bitter orange oil, cardamom oil, cinnamon oil, and clove oil, have low solubility in solvents such as ethylene glycol and glycerol, affecting the taste. Increasing the content of low-polarity flavor compounds can lead to inconsistent taste due to uneven dispersion, and may even cause burning during atomization. On the other hand, solvents such as ethylene glycol and glycerol are usually the main source of sufficient smoke production. If solvents such as ethanol and propanol are partially replaced by ethylene glycol and glycerol, the smoke production will be significantly reduced. In addition, the use of large amounts of solvents such as ethanol and propanol will lower the flash point of the atomizing liquid, which can easily cause fire safety risks during storage, transportation, and production.

[0024] Therefore, in order to ensure both uniform dissolution of sufficient low-polarity aroma substances, consistent taste after atomization without burning, and sufficient vapor production, the first aspect of this disclosure aims to provide an atomizing liquid for use in a compartmentalized atomizing device. The atomizing liquid comprises a first liquid and a second liquid, wherein the first liquid and the second liquid are stored independently in the compartmentalized atomizing device. The first liquid comprises a first solvent and a first solute, and the second liquid comprises a second solvent and a second solute. The first solvent comprises at least a type A solvent, and the second solvent comprises at least a type C solvent. Type A solvents include one or more of ethanol, propanol, butanol, and benzyl alcohol, and type C solvents include one or more of water, ethylene glycol, glycerol, and glycerol. The proportion of the total mass of type A solvents in the second solvent is less than the proportion of the total mass of type A solvents in the first solvent, or the proportion of the total mass of type C solvents in the second solvent is greater than the proportion of the total mass of type C solvents in the first solvent.

[0025] This disclosure utilizes a compartmentalized atomizing device, designing an atomizing liquid comprising a first liquid and a second liquid. The first liquid, containing a large amount of low-polarity flavorings (such as sweet orange oil, lemon oil, etc.) or low-polarity aroma substances (such as pinene, limonene, myrcene, caryophyllene, nonanol, decanol, lauryl alcohol, and propyl undecyl lactone rose ether, etc.), and the second liquid, containing a solvent capable of producing a large amount of vapor, are atomized separately. The first liquid is a dissolving system with a higher proportion of type A solvents, which have a high ability to dissolve low-polarity aroma substances, thus ensuring the uniform dissolution of a large number of low-polarity aroma substances. The second liquid is a dissolving system with a higher proportion of type C solvents, which can provide sufficient vapor volume and ensure the uniform dissolution of a large number of high-polarity aroma substances. The first and second liquids, stored independently in the compartmentalized atomizing device, mix the vapors after separate atomization, thereby achieving both uniform dissolution of sufficient low-polarity aroma substances, improved and consistent taste after atomization without burning, and sufficient vapor volume.

[0026] Commonly used solvents in atomizing fluids include water, ethanol, ethylene glycol, propanol, propylene glycol, glycerol, butanol, butanediol, benzyl alcohol, triethyl citrate, triacetin, and caprylic / capric triglycerides. According to embodiments of this disclosure, type A solvents include ethanol, propanol, butanol, and benzyl alcohol, while type C solvents include water, ethylene glycol, glycerol, and propylene glycol. By differentiating the solvent polarities of the first and second liquids in the atomizing fluid, the first and second liquids can uniformly dissolve solutes with significantly different polarities, and the second liquid does not need to consider the dissolution of low-polarity solutes, thus including sufficient type C solvents to provide adequate vapor volume.

[0027] The first and / or second solvents disclosed herein further include type B solvents. The type B solvents include one or more of propylene glycol, butanediol, triethyl citrate, triacetin, and caprylic / capric triglycerides.

Exemplarily, the total mass percentage of the C-type solvent and the B-type solvent in the second solvent is 65%, 70%, 75%, 80%, 85%, 90%, 92%, or 95%. Within the above ranges, the C-type solvent and the B-type solvent are more conducive to the uniform dissolution of a larger amount of highly polar flavoring substances in the second solvent.

[0032] In some embodiments, the total mass percentage of the Class C solvent in the second solvent is 20%-60%, preferably 30%-50%, based on its mass percentage in the second liquid. Exemplarily, the total mass percentage of the Class C solvent in the second solvent is 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, or 60%.

[0034] In some embodiments, the total mass percentage of type B solvent in the second solvent is 0%-75%, preferably 30-65%, and more preferably 45-55% by mass percentage in the second liquid. Exemplarily, the total mass percentage of type B solvent in the second solvent is 0%, 10%, 20%, 30%, 35%, 40%, 45%, 47%, 50%, 53%, 55%, 60%, 65%, 70%, or 75%.

[0035] According to some embodiments of this disclosure, the proportion of the total mass of substances with a n-octanol-water partition coefficient greater than 0.73 in the first solute is greater than the proportion of the total mass of substances with a n-octanol-water partition coefficient greater than 0.73 in the second solute; or, the proportion of the total mass of substances with a n-octanol-water partition coefficient less than -0.74 in the first solute is less than the proportion of the total mass of substances with a n-octanol-water partition coefficient less than -0.74 in the second solute. Accurately quantifying the polarity of the solute using the n-octanol-water partition coefficient differentiates the polarity of the solutes in the first and second liquids of the atomized liquid, which facilitates the uniform dissolution of more solutes with significant polarity differences in the first and second liquids.

[0036] The “octanol-water partition coefficient” refers to the standard GB / T 21853-2008 Chemical Partition Coefficient (octanol-water) Shake Flask Method Test, wherein the octanol-water partition coefficient of the analyte is logK = log(analyte concentration in octanol (mol / L) / analyte concentration in water (mol / L)).

The aforementioned substances with a n-octanol-water partition coefficient less than -0.74 can reduce irritation or increase satisfaction, or achieve certain special tastes, such as sweetness and coolness.

[0039] The first and / or second solutes of this disclosure further include substances with an octanol-water partition coefficient greater than or equal to -0.74 and less than or equal to 0.73. Exemplarily, the substances with an octanol-water partition coefficient greater than or equal to -0.74 and less than or equal to 0.73 may be dimethyl glutarate, octanedione, ethylene acetone, ethyl lactate, etc. Such substances can help substances with an octanol-water partition coefficient less than -0.74 or greater than 0.73 to exhibit better odor or flavor.

[0040] According to some embodiments of this disclosure, the total mass percentage of substances in the first solute with an octanol-water partition coefficient greater than or equal to -0.74 is 2%-30%, preferably 5%-15%, based on their mass percentage in the first liquid.

[0042] In some embodiments, the total mass percentage of substances in the first solvent with an octanol-water partition coefficient greater than or equal to -0.74 and less than or equal to 0.73 is 0%-28%, preferably 0-15%, and more preferably 0-5%, based on their mass percentage in the first liquid.

[0050] The present disclosure will be further described below with reference to specific embodiments. All raw materials involved are obtained through commercial purchase.

[0051] Example

[0052] Examples 1-3 and Comparative Examples 1-3

[0053] According to the formulations shown in Table 1, the components were mixed evenly to obtain the first and second liquids of the atomizing liquids for Examples 1-3, wherein each raw material component is expressed as a percentage by mass. The atomizing liquids of Examples 1-3 and Comparative Examples 1-3 were tested using a compartmentalized electronic atomizing device with two storage chambers. The first and second liquids of Examples 1-3 were stored independently in the two storage chambers of the compartmentalized electronic atomizing device. In Comparative Example 1, the first and second liquids of Example 1 were mixed evenly, then divided into two equal portions by mass, and these two portions were placed in the two storage chambers of the compartmentalized electronic atomizing device respectively; that is, the first and second liquids were not stored independently. In Comparative Example 2, the first liquid from Example 1 was placed simultaneously in the two storage chambers of the compartmentalized electronic atomizing device. In Comparative Example 3, the second liquid from Example 1 was placed simultaneously in the two storage chambers of the compartmentalized electronic atomizing device.

[0054] Table 1. Weight parts of each component in the atomizing liquid of Examples 1-3 and Comparative Examples 1-3

[0055]

[0056]

[0057] As shown in Table 1, the e-liquid in both storage tanks of Examples 1-3 was uniformly clear, meaning that each first solute was uniformly dispersed in its corresponding first solvent, and each second solute was uniformly dispersed in its corresponding second solvent. In Comparative Example 1, the originally uniformly clear first and second liquids from Examples 1 were mixed, resulting in turbidity and stratification, with suspended small droplets appearing.

[0058] Sensory evaluation test

[0059] A panel of six individuals, selected through sensory evaluation, conducted sensory assessments of the atomizing liquids containing Examples 1-3 and Comparative Examples 1-3, using smoke volume, aroma reproduction, aroma intensity, sweetness, and consistency as evaluation indicators. To eliminate differences in electronic atomization devices, three parallel samples were prepared for each example and comparative example. To eliminate mutual influence between samples, the evaluators rinsed their mouths and throats with 200 mL of purified water before evaluating each sample and remained silent until the sweetness of the previous sample had completely dissipated.

[0060] Each person performed a vaping test on each of all the examples and comparative samples, using a holistic cyclical vaping evaluation method. A blind vaping scoring method was employed, and based on the meanings of the four sensory quality evaluation indicators (smoke volume, aroma fidelity, aroma intensity, and sweetness) in Table 2, the average score of all vapers was taken for each item of each vaporizer sample. Furthermore, if more than half of the six sensory personnel indicated poor vaping consistency, off-odors, or a burnt / bitter taste, the sample was considered to have poor vaping consistency or an off-odor. The sensory evaluation results are shown in Table 3.

[0061] Table 2 Scoring Criteria for Sensory Evaluation of Electronic Atomizing Fluids

[0062] Score smoke volume Aroma fidelity Aroma intensity Sweetness 9 adequate very good Very strong Very sweet 8 foot good powerful sweet 7 More adequate better Strong Sweeter 6 Slightly sufficient Slightly better Slightly heavier Slightly sweet 5 middle middle middle middle 4 Slightly Slightly worse Slightly weak Slightly lighter 3 Lighter Poor Weak Lighter 2 light Difference weak light 1 Very light Very bad Very weak Very light

[0063] Table 3 Sensory evaluation of the examples and comparative samples

[0064] sample smoke volume Aroma fidelity Aroma intensity Sweetness consistency Example 1 8.22 8.15 8.22 7.45 Good consistency and no odor Example 2 8.40 8.11 8.09 7.19 Good consistency and no odor Example 3 8.31 8.34 8.18 7.22 Good consistency and no odor Comparative Example 1 8.13 6.77 7.01 6.49 Poor consistency and unpleasant odor Comparative Example 2 1.25 5.08 7.11 1 Odorless Comparative Example 3 8.09 1 1 8.87 Odorless

[0065] Based on the formulation in Table 1 and the data in Table 3, it can be seen that in Example 1, the first liquid only includes substances with a n-octanol-water partition coefficient greater than 0.73, and the second liquid only includes substances with a n-octanol-water partition coefficient less than -0.74. This achieves a rich and reducing aroma, good taste consistency, no off-odors, and sufficient smoke. In Example 2, the first liquid includes a small amount of substances with a n-octanol-water partition coefficient less than -0.74. The total mass percentage of substances with a n-octanol-water partition coefficient greater than 0.73 in the first liquid is greater than that in the second liquid, also achieving good taste and aroma. In Example 3, the total mass percentage of substances with a n-octanol-water partition coefficient less than -0.74 in the first liquid is greater than the total mass percentage of substances with a n-octanol-water partition coefficient greater than 0.73, and the total mass percentage of substances with a n-octanol-water partition coefficient greater than 0.73 in the first liquid is greater than the total mass percentage of substances with a n-octanol-water partition coefficient greater than 0.73 in the second liquid, which can also achieve good taste and aroma.

[0066] In Comparative Example 1, both storage chambers contained a mixture of the first and second liquids from Example 1, resulting in suspended small droplets. These droplets were clustered together, consisting of aroma compounds with similar polarities. As the atomizing liquid was gradually consumed, while the flavor was relatively rich when the small droplet areas were atomized, the limited solvent content meant that the simultaneous evaporation and dissipation of heat by the solvent created localized high-temperature spots, leading to a higher risk of scorching. Since most of the aroma compounds were concentrated in the small droplets, the flavor was not as rich and accurate when the non-small droplet areas of the atomizing liquid were atomized. This random atomization of the small and non-small droplet areas resulted in an inconsistent flavor before and after vaping.

[0067] In Comparative Example 2, both storage chambers contained the first liquid from Example 1. Due to the lack of the second liquid and the absence of Class C solvent, the variety of aroma substances was limited, the aroma reduction was significantly reduced, and the amount of smoke was weak. In Comparative Example 3, both storage chambers contained the second liquid from Example 1. Due to the lack of the first liquid, the variety of aroma substances was limited, especially the lack of aroma substances with a n-octanol-water partition coefficient greater than -0.74, resulting in a very unpleasant sensation.
