Description

Technical Field

[0001] This application belongs to the technical field of electronic atomization, and particularly relates to an atomization liquid, a cartridge-type atomizer, and an electronic atomization device. Background Art

[0002] Generally, rich flavor substances such as flavors and fragrances are dissolved in the atomization liquid in an electronic atomization device, so a variety of flavors and differentiated tastes can be presented. The polarity differences of these flavor substances may be very large. Among them, some low-polarity flavor substances are often required to achieve a highly restored rich taste. However, such substances are often difficult to dissolve in solvents including a large amount of ethylene glycol, glycerol, etc., and there will be a layering of low-polarity flavor substances and solvents, and then problems such as inconsistent taste or even charring may occur during puffing. On the other hand, solvents such as ethylene glycol and glycerol are usually the main sources of generating sufficient smoke volume. If solvents such as propylene glycol and ethanol are used to replace solvents such as ethylene glycol and glycerol, it will cause a significant reduction in the smoke volume.

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

[0017] In addition to the technical problems solved by the present disclosure, the technical features constituting the technical solutions, and the beneficial effects brought by the technical features of these technical solutions described above, other technical problems that the present disclosure can solve, other technical features included in the technical solutions, and the beneficial effects brought by these technical features will be further described in detail in the following specific embodiments. Specific Embodiments

[0018] The technical solutions of the present disclosure will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the scope of protection of this application.

[0019] Throughout the specification, unless otherwise specifically stated, the terms used herein should be understood to have the meanings as commonly used in the art. Therefore, unless otherwise defined, all technical and scientific terms used herein have the same meaning as the general understanding of those skilled in the art to which this disclosure belongs. In case of any conflict, this specification shall prevail.

[0020] It should be noted that in the present disclosure, the term "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, such that a method or apparatus comprising a series of elements includes not only those elements explicitly recited, but also other elements not explicitly listed, or elements inherent to the implementation of the method or apparatus. Without further limitation, the element defined by the statement "comprising..." does not exclude the existence of additional related elements in the method or apparatus comprising such element.

[0021] The percentage content or % in the present disclosure is, unless otherwise specified, the mass percentage content or mass %.

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

[0023] Low-polarity flavor substances, such as pinene, limonene, myrcene, caryophyllene, nonanal, decanal, lauryl alcohol, gamma-undecalactone, rose ether, etc., or natural extract fragrances containing a large amount of low-polarity flavor substances, such as sweet orange oil, bitter almond oil, bitter orange oil, cardamom oil, cinnamon oil, clove oil, etc., have low solubility in solvents such as ethylene glycol and glycerol, which affects the taste. If the content of low-polarity flavor substances is increased, the taste will be inconsistent due to the inability to disperse evenly, and even charring will occur during atomization. On the other hand, solvents such as ethylene glycol and glycerol are usually the main sources of generating sufficient smoke volume. If ethanol, propanol and other solvents are used to partially replace ethylene glycol, glycerol and other solvents, the smoke volume will be significantly reduced. In addition, when a large amount of ethanol, propanol and other solvents are used, the flash point of the atomizing liquid will be reduced, which is likely to cause fire safety risks during storage, transportation and production.

[0024] Therefore, in order to uniformly dissolve sufficient low-polarity aroma substances, have a consistent taste after atomization without charring, and be able to provide sufficient smoke volume, the first aspect of the present disclosure aims to provide an atomizing liquid applied to a partitioned atomizing device. The atomizing liquid includes a first liquid and a second liquid. Among them, the first liquid and the second liquid are independently stored in the partitioned atomizing device. The first liquid includes a first solvent and a first solute, and the second liquid includes a second solvent and a second solute. The first solvent at least includes A-type solvents, and the second solvent at least includes C-type solvents. Among them, the A-type solvents include one or more of ethanol, propanol, butanol, and benzyl alcohol, and the C-type solvents include one or more of water, ethylene glycol, butanetriol, and glycerol; the total mass of the A-type solvents in the second solvent accounts for less than the total mass of the A-type solvents in the first solvent in the first solvent, or the total mass of the C-type solvents in the second solvent accounts for more than the total mass of the C-type solvents in the first solvent in the first solvent.

[0025] The present disclosure utilizes a compartmentalized atomization device to design an atomization liquid including a first liquid and a second liquid. It can atomize the first liquid containing a large amount of low-polarity substances such as essence (e.g., sweet orange oil, lemon oil, etc.) or low-polarity aroma substances (e.g., pinene, limonene, myrcene, caryophyllene, nonanol, decanol, lauryl alcohol, gamma-undecalactone, rose oxide, etc.) separately from the second liquid containing a solvent that can produce a large amount of smoke. Among them, the first liquid is a dissolution system with a relatively large proportion of Class A solvents, and Class A solvents have a high ability to dissolve low-polarity flavor substances, so that more low-polarity flavor substances can be evenly dissolved. The second liquid is a dissolution system with a relatively large proportion of Class C solvents. Class C solvents can provide an abundant amount of smoke and evenly dissolve more high-polarity flavor substances. The first liquid and the second liquid stored separately and independently in the compartmentalized atomization device are mixed after being atomized respectively, so as to achieve both the uniform dissolution of sufficient low-polarity aroma substances, an improved taste and good consistency after atomization without charring, and the provision of an abundant amount of smoke.

By differentiating the solvent polarities of the first liquid and the second liquid in the atomization liquid, the first liquid and the second liquid can respectively and evenly dissolve solutes with large polarity differences, and the second liquid does not need to consider the dissolution problem of low-polarity solutes and can include sufficient Class C solvents to provide an abundant amount of smoke.

[0027] The first solvent and / or the second solvent of the present disclosure further includes a Class B solvent. The Class B solvent includes one or more of propylene glycol, butylene glycol, triethyl citrate, glyceryl triacetate, and glyceryl caprylocaprate.

When the solvent of type C and the solvent of type B are within the above range, it is more beneficial for the second solvent to uniformly dissolve more high-polarity flavor substances.

[0032] In some embodiments, based on the mass percentage in the second liquid, the total mass percentage of the solvent of type C in the second solvent is 20%-60%, preferably 30%-50%.

By accurately quantifying the polarity of the solute through the octanol-water partition coefficient, the polarity of the solutes in the first liquid and the second liquid in the atomized liquid is differentiated, which is beneficial to the uniform dissolution of more solutes with large polarity differences in the first liquid and the second liquid respectively.

[0036] The "octanol-water partition coefficient" refers to the test method of the shake flask method for the partition coefficient (octanol-water) of chemicals in GB / T 21853-2008.

[0051] Embodiment

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

[0053] According to the formulations shown in Table 1, each component was uniformly mixed to obtain the first liquid and the second liquid of the atomization liquid of Examples 1-3, where each raw material component was calculated by mass percentage. A multi-chamber electronic atomization device with two liquid storage chambers was used to perform the following tests on the atomization liquid of Examples 1-3 and Comparative Examples 1-3. Among them, the first liquid and the second liquid of Examples 1-3 were independently stored in the two liquid storage chambers of the multi-chamber electronic atomization device. In Comparative Example 1, the first liquid and the second liquid of Example 1 were uniformly mixed, then evenly divided into two parts by mass, and then these two parts were respectively placed in the two liquid storage chambers of the multi-chamber electronic atomization device, that is, the first liquid and the second liquid were not independently stored. In Comparative Example 2, the first liquid in Example 1 was placed in the two liquid storage chambers of the multi-chamber electronic atomization device at the same time. In Comparative Example 3, the second liquid in Example 1 was placed in the two liquid storage chambers of the multi-chamber electronic atomization device at the same time.

[0055]

[0056]

[0057] As shown in Table 1, the e-liquid states in the two liquid storage chambers of Examples 1-3 were both uniformly clear, that is, each first solute was uniformly dispersed in the corresponding first solvent, and each second solute was uniformly dispersed in the corresponding second solvent. In Comparative Example 1, the originally uniformly clear first liquid and second liquid of the example were mixed, resulting in turbidity and stratification, and suspended small droplets appeared.

[0058] Sensory evaluation test

[0059] A six-member evaluation panel consisting of personnel who passed the sensory ability assessment was selected. Using the amount of smoke, aroma reduction, aroma intensity, sweetness, and consistency as evaluation indicators, sensory evaluations were conducted on the e-liquids filled with Examples 1-3 and Comparative Examples 1-3. To eliminate the differences in e-cigarette devices, three parallel samples were arranged for each example and comparative example. To eliminate the mutual influence between samples, the evaluators rinsed their mouths and throats with 200 mL of pure water before evaluating each sample and remained silent until the sweet taste of the previous sample completely dissipated.

[0060] Each person sucked each of all the example and comparative example samples using the overall cyclic puffing method; using the blind evaluation scoring method, according to the meanings of the scoring values of the four sensory quality evaluation indicators (amount of smoke, aroma reduction, aroma intensity, sweetness) in Table 2, for each item of each e-liquid sample, the average value of the scores of all puffing evaluators was taken. In addition, when more than half of the six sensory personnel pointed out poor puffing consistency, off-flavor, or burnt bitterness, the sample was regarded as having poor puffing consistency and off-flavor. The sensory evaluation results are shown in Table 3.

[0065] Combined with the formula of Table 1, it can be seen from the data in Table 3 that in Example 1, the first liquid only includes substances with an n-octanol-water partition coefficient greater than 0.73, and the second liquid only includes substances with an n-octanol-water partition coefficient less than -0.74, which can achieve a rich and reduced aroma, and a good taste consistency, no odor, and sufficient smoke. In Example 2, the first liquid includes a small amount of substances with an n-octanol-water partition coefficient less than -0.74, and the total mass proportion of substances with an n-octanol-water partition coefficient greater than 0.73 in the first liquid is greater than the total mass proportion of substances with an n-octanol-water partition coefficient greater than 0.73 in the second liquid, which can also achieve a good taste and aroma. In Example 3, the total mass proportion of substances with an n-octanol-water partition coefficient of less than -0.74 in the first liquid is greater than the total mass proportion of substances with an n-octanol-water partition coefficient greater than 0.73, and the total mass proportion of substances with an n-octanol-water partition coefficient greater than 0.73 in the first liquid is greater than the total mass proportion of substances with an n-octanol-water partition coefficient greater than 0.73 in the second liquid, which can also achieve good taste and aroma.

[0066] The two liquid storage tanks of Comparative Example 1 contain a mixture of the first liquid and the second liquid of Example 1, in which suspended small droplets are produced. These small droplets are aromatic substances with similar polarity gathered together. In the process of gradual consumption of the atomized liquid, when the small droplet area is atomized, although the taste is relatively strong, due to the small amount of solvent in the droplets, the heat cannot be taken away by the simultaneous atomization and evaporation of the solvent during atomization, forming local high-temperature points, which leads to a higher risk of burning. Since most of the aromatic substances are gathered in small droplets, when the non-small droplet area in the atomized liquid is atomized, the taste is not rich enough. The random atomization of the small droplet area and the non-small droplet area leads to inconsistent taste before and after inhalation.

[0067] The two liquid storage tanks of Comparative Example 2 are both filled with the first liquid of Example 1. Due to the lack of the second liquid and the lack of Class C solvents, the types of aroma substances are limited, the aroma reduction degree is significantly reduced, and the smoke volume is weak. The two liquid storage tanks of Comparative Example 3 are both filled with the second liquid of Example 1. Due to the lack of the first liquid and the limited types of aroma substances, especially the lack of aroma substances with a n-octanol-water partition coefficient greater than -0.74, a very uncoordinated feeling is produced.
