[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure is based on the Chinese patent application with application number 202410065652.7, application date January 16, 2024, and invention name “Atomizing liquid, compartment-type atomizer and electronic atomizing device”, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into the present disclosure as a reference. Technical Field

[0003] The present disclosure belongs to the technical field of electronic atomization, and in particular relates to an atomizing liquid, a compartment-type atomizer, and an electronic atomization device. Background Art

[0004] Usually, the atomizing liquid in the electronic atomization device contains a rich variety of flavors, spices and other aromatic substances, so it can present a variety of flavors and differentiated tastes. The polarity of these aromatic substances may vary greatly, and some low-polarity aromatic substances are often required to achieve a highly reduced rich taste. However, such substances are often difficult to dissolve in solvents including a large amount of ethylene glycol, glycerol, etc., resulting in stratification of low-polarity aromatic substances and solvents, and then problems such as inconsistent taste or even burning during the inhalation process. On the other hand, solvents such as ethylene glycol and glycerol are usually the main source of sufficient smoke production. If solvents such as propylene glycol and ethanol are used instead of ethylene glycol and glycerol, the amount of smoke will be significantly reduced.

[0005] Therefore, it is necessary to provide an improved atomized liquid. Summary of the Invention

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions of the present disclosure in conjunction with specific embodiments. Obviously, the embodiments described 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 making any creative efforts are within the scope of protection of the present disclosure.

[0021] Throughout this specification, unless otherwise specified, the terms used herein should be understood as having the same 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 those skilled in the art. In the event of any conflict, the present specification shall take precedence.

[0022] It should be noted that, in this disclosure, the term "comprising" or any other variant thereof is intended to encompass non-exclusive inclusion, such that a method or apparatus comprising a series of elements includes not only the elements explicitly recited, but also other elements not explicitly listed, or elements inherent to the implementation of the method or apparatus. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of other related elements in the method or apparatus comprising the element.

[0023] Unless otherwise specified, percentages or % in the present disclosure are all percentages or % by mass.

[0024] It should be understood that references throughout this specification to "one embodiment" or "some embodiments" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present disclosure. Therefore, the appearances of "in one embodiment" or "in some embodiments" throughout this specification do not necessarily refer to the same embodiment.

[0025] Low-polarity flavoring substances, such as pinene, limonene, myrcene, caryophyllene, nonanal, decanal, lauryl alcohol, gamma-undecalactone, rose oxide, etc., or natural extract flavors containing a large amount of low-polarity flavoring 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, affecting the mouthfeel. If the content of low-polarity flavoring substances is increased, the taste will be inconsistent due to the inability to disperse evenly, and even burn 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 used to partially replace solvents such as ethylene glycol and glycerol, the amount of smoke will be significantly reduced. In addition, when solvents such as ethanol and propanol are used in large quantities, the flash point of the atomized liquid will be reduced, which can easily cause fire safety risks during storage, transportation and production.

[0026] Therefore, in order to make sufficient low-polarity aroma substances dissolve evenly, have a consistent taste after atomization, not burnt, and provide sufficient smoke volume, the first aspect of the present disclosure is intended to provide an atomizing liquid for use in a compartment-type atomizing device. The atomizing liquid includes a first liquid and a second liquid, wherein the first liquid and the second liquid are independently stored in the compartment-type atomizing device, the first liquid includes a first solvent and a first solute, the second liquid includes a second solvent and a second solute, the first solvent includes at least a Class A solvent, and the second solvent includes at least a Class C solvent, wherein the Class A solvent includes one or more of ethanol, propanol, butanol, and benzyl alcohol, and the Class C solvent includes one or more of water, ethylene glycol, butanetriol, and glycerol; the proportion of the total mass of the Class A solvent in the second solvent in the second solvent is less than the proportion of the total mass of the Class A solvent in the first solvent in the first solvent, or the proportion of the total mass of the Class C solvent in the second solvent in the second solvent is greater than the proportion of the total mass of the Class C solvent in the first solvent in the first solvent.

[0027] The present invention utilizes a compartment-type atomizing device to design an atomizing liquid including a first liquid and a second liquid. The first liquid containing a large amount of low-polarity essence (such as sweet orange oil, lemon oil, etc.) or low-polarity aroma substances (such as pinene, limonene, myrcene, caryophyllene, nonanol, decanol, lauryl alcohol, propyl undecanoate rose oxide, etc.) and the second liquid containing a solvent that can produce a large amount of smoke can be atomized separately. Among them, the first liquid is a dissolving system with a relatively large proportion of Class A solvents, and Class A solvents have a high ability to dissolve low-polarity aroma substances, thereby uniformly dissolving more low-polarity aroma substances. The second liquid is a dissolving system with a relatively large proportion of Class C solvents, and Class C solvents can provide sufficient smoke volume and uniformly dissolve more high-polarity aroma substances. The first liquid and the second liquid, which are independently stored in the compartment-type atomizing device, are mixed after being atomized separately, thereby achieving both uniform dissolution of sufficient low-polarity aroma substances, improved taste and good consistency after atomization, and no burnt, and providing sufficient smoke volume.

[0028] Commonly used solvents in atomized liquids include water, ethanol, ethylene glycol, propanol, propylene glycol, glycerol, butanol, butylene glycol, butanetriol, benzyl alcohol, triethyl citrate, glyceryl triacetate, and glyceryl caprylate. According to an embodiment of the present disclosure, Class A solvents include solvents such as ethanol, propanol, butanol, and benzyl alcohol, and Class C solvents include solvents such as water, ethylene glycol, butanetriol, and glycerol. By differentiating the polarity of the first and second liquids in the atomized liquid, the first and second liquids can each uniformly dissolve solutes with greatly different polarities. Moreover, the second liquid does not need to consider the dissolution of low-polarity solutes and can include sufficient Class C solvent to provide a sufficient amount of smoke.

[0029] The first solvent and / or 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, triacetin, and caprylic decanoic acid glyceryl. The Class B solvent can assist the Class C solvent or the Class A solvent in dissolving substances of moderate polarity.

[0030] According to some embodiments of the present disclosure, the total mass percentage of the Class A solvent and the Class B solvent in the first solvent is 60%-98%, preferably 70%-95%, by mass percentage in the first liquid. For example, the total mass percentage of the Class A solvent and the Class B solvent in the first solvent is 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 98%. The Class A and Class B solvents within the above ranges are more conducive to uniformly dissolving a larger amount of low-polarity aroma substances in the first solvent.

[0031] In some embodiments, the total mass percentage of the Class A solvent in the first solvent is 60%-95%, preferably 70%-90%, by mass percentage in the first liquid. Exemplarily, the total mass percentage of the Class A solvent in the first solvent is 60%, 65%, 70%, 75%, 80%, 85%, 90%, or 95%. The Class A solvent content within the above range further facilitates uniform dissolution of a larger amount of low-polarity aroma substances in the first solvent.

[0032] In some embodiments, the total mass percentage of the Class B solvents in the first solvent is 0%-38%, preferably 5-25%, and more preferably 5-15%, calculated as a mass percentage in the first liquid. The total mass percentage of the Class B solvents in the first solvent is 0%, 3%, 5%, 8%, 10%, 12%, 15%, 20%, 25%, 30%, 35%, or 38%.

[0033] According to some embodiments of the present disclosure, the total mass percentage of the Class C solvent and the Class B solvent in the second solvent is 60%-95%, preferably 70%-92%, by mass percentage in the second liquid. Exemplarily, the total mass percentage of the Class C solvent and the Class B solvent in the second solvent is 65%, 70%, 75%, 80%, 85%, 90%, 92%, or 95%. Within the above ranges, the Class C solvent and the Class B solvent are more conducive to uniformly dissolving a larger amount of high-polarity aroma substances in the second solvent.

[0034] In some embodiments, the total mass percentage of the Class C solvent in the second solvent is 20%-60%, preferably 30%-50%, by 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%. Within the above range, the Class C solvent further facilitates uniform dissolution of a larger amount of highly polar aroma substances in the second solvent and provides a sufficient amount of aerosol.

[0035] According to a specific embodiment, the mass percentage of glycerol in the second solvent is 20%-60%, preferably 30%-50%, based on the mass percentage of the second liquid. Exemplarily, the mass percentage of glycerol in the second solvent is 0%, 10%, 20%, 30%, 35%, 37%, 40%, 43%, 45%, 50%, or 60%. Glycerol within the above range is more conducive to achieving high smoke yields.

[0036] In some embodiments, the total mass percentage of the Class 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 the Class B solvent in the second solvent is 0%, 10%, 20%, 30%, 35%, 40%, 45%, 47%, 50%, 53%, 55%, 60%, 65%, 70%, or 75%.

[0037] According to some embodiments of the present disclosure, the proportion of the total mass of the substance with an n-octanol-water partition coefficient greater than 0.73 in the first solute is greater than the proportion of the total mass of the substance with an n-octanol-water partition coefficient greater than 0.73 in the second solute, or the proportion of the total mass of the substance with an n-octanol-water partition coefficient less than -0.74 in the first solute is less than the proportion of the total mass of the substance with an n-octanol-water partition coefficient less than -0.74 in the second solute. The polarity of the solute is accurately quantified by the n-octanol-water partition coefficient, so that the polarity of the solutes in the first liquid and the second liquid in the atomized liquid is differentiated, which is conducive to more solutes with large polarity differences to uniformly dissolve the first liquid and the second liquid respectively.

[0038] The “n-octanol-water partition coefficient” is based on the shake flask test method for chemical partition coefficients (n-octanol-water) in accordance with GB / T 21853-2008, wherein the n-octanol-water partition coefficient of the test substance, log K, is calculated as follows: (concentration of the test substance in n-octanol (mol / L) / concentration of the test substance in water (mol / L)).

[0039] According to some embodiments of the present disclosure, the substance having an n-octanol-water partition coefficient greater than 0.73 includes one or more of pinene, limonene, myrcene, caryophyllene, nonanal, decanal, lauryl alcohol, gamma-undecalactone, rose oxide, thujone, camphene, sabinene, phellandrene, terpinene, cymene, limonene, ocimene, terpineol, terpinolene, linalool, octanal, neral, geranyl, nerol, geraniol, perillaldehyde, undecanal, dodecanal, and farnesene. The substances having an n-octanol-water partition coefficient greater than 0.73 can achieve high taste restoration and aroma richness.

[0040] According to some embodiments of the present disclosure, the substance having an n-octanol-water partition coefficient of less than -0.74 includes one or more of neotame, advantame, sucralose, acesulfame potassium, glucosyl steviol glycosides, aspartame, hesperidin dihydrochalcone, neohesperidin dihydrochalcone, naringin dihydrochalcone, WS-3, WS-5, WS-12, WS-14, WS-23, WS-25, WS-27, menthol, menthol ether, menthyl ester, nicotine benzoate, nicotine levulinate, nicotine tartrate, nicotine citrate, nicotine acetate, and nicotine oxalate. The above substances having an n-octanol-water partition coefficient of less than -0.74 can reduce irritation or increase satisfaction, or achieve certain special tastes, such as sweetness and cooling.

[0041] The first solute and / or the second solute of the present disclosure further include substances having an n-octanol-water partition coefficient greater than or equal to -0.74 and less than or equal to 0.73. For example, the substance having an n-octanol-water partition coefficient greater than or equal to -0.74 and less than or equal to 0.73 may be dimethyl glutarate, octanedione, ethyl acetone, ethyl lactate, etc. Such substances can assist substances having an n-octanol-water partition coefficient less than -0.74 or substances having an n-octanol-water partition coefficient greater than 0.73 to present a better smell or taste.

[0042] According to some embodiments of the present disclosure, the total mass percentage of substances having an n-octanol-water partition coefficient greater than or equal to -0.74 in the first solute is 2%-30%, preferably 5%-15%, measured by mass percentage in the first liquid. For example, the total mass percentage of substances having an n-octanol-water partition coefficient greater than or equal to -0.74 in the first solvent is 2%, 3%, 5%, 8%, 10%, 13%, 15%, 17%, 20%, 25%, or 30%. When the n-octanol-water partition coefficient is greater than or equal to -0.74 within the above range, it is more conducive to uniform dissolution of such substances in the first solvent.

[0043] According to some embodiments of the present disclosure, the total mass percentage of substances with an n-octanol-water partition coefficient greater than 0.73 in the first solute is 2%-15%, preferably 4%-10%, by mass percentage in the first liquid. For example, the total mass percentage of substances with an n-octanol-water partition coefficient greater than 0.73 in the first solvent is 2%, 3%, 4%, 6%, 8%, 10%, 13%, or 15% in the first liquid. The presence of substances with an n-octanol-water partition coefficient greater than 0.73 within the above range further facilitates uniform dissolution of such substances in the first solvent.

[0044] In some embodiments, the total mass percentage of substances having an n-octanol-water partition coefficient greater than or equal to -0.74 and less than or equal to 0.73 in the first solvent is 0% to 28%, preferably 0% to 15%, and more preferably 0% to 5%, by mass percentage in the first liquid. For example, the total mass percentage of such substances in the first solvent is 0%, 0.5%, 1%, 2%, 5%, 10%, 15%, 20%, or 25%.

When the n-octanol-water partition coefficient is less than or equal to 0.73 within the above range, it is more conducive to uniform dissolution of such substances in the second solvent.

[0046] According to some embodiments of the present disclosure, the total mass percentage of substances with an n-octanol-water partition coefficient less than -0.74 in the second solute, measured by mass percentage in the second liquid, is 5%-20%, preferably 9%-15%. Exemplarily, the total mass percentage of substances with an n-octanol-water partition coefficient less than -0.74 in the second solvent is 5%, 8%, 10%, 13%, 15%, 18%, or 20%. The presence of substances with an n-octanol-water partition coefficient less than -0.74 within the above range further facilitates uniform dissolution of such substances in the second solvent.

[0047] In some embodiments, the total mass percentage of substances having an n-octanol-water partition coefficient greater than or equal to -0.74 and less than or equal to 0.73 in the second solvent is 0% to 25%, preferably 0% to 15%, and more preferably 0% to 5%, by mass percentage in the second liquid. For example, the total mass percentage of such substances in the second solvent is 0%, 0.5%, 1%, 2%, 5%, 10%, 15%, 20%, or 25%.

[0048] The present disclosure has no particular limitation on the preparation method of the first and second liquids of the atomized liquid, which may generally include a step of uniformly mixing the components. According to some embodiments, heating may be performed to accelerate dissolution, for example, heating at about 30°C-50°C for 10-20 minutes.

[0049] The second aspect of the present disclosure provides a compartment-type atomizer. The atomizer includes the atomized liquid according to any of the above embodiments. Exemplarily, the atomizer has two liquid storage tanks for independent storage of the first liquid and the second liquid of the atomized liquid. Exemplarily, the atomizing assembly of the atomizer can be one, having two liquid inlet ports, which are respectively connected to the fluid of the two liquid storage tanks. Exemplarily, the atomizing assembly can be two, each atomizing assembly having a liquid inlet port, which are respectively connected to the fluid of the two liquid storage tanks. Optionally, the atomizer can also have more than two liquid storage tanks, or other compartment-type configurations. The present disclosure does not impose specific restrictions on this, as long as it can ensure that the first liquid and the second liquid are stored independently.

[0050] The atomizing liquid disclosed herein can be applied to various types of atomizing components, such as resistance heating atomizing components, flat sheet ultrasonic atomizing components, vibrating mesh atomizing components, electrostatic atomizing components, infrared atomizing components and microwave atomizing components, but is not limited thereto.

[0051] According to a third aspect of the present disclosure, an electronic atomization device is provided, comprising a battery assembly and an atomizer according to any one of the above embodiments, wherein the battery assembly is used to power the atomizer.

[0052] The present disclosure is further described below with reference to specific examples. All raw materials involved were purchased from commercial sources.

[0053] Example

[0054] Examples 1-3 and Comparative Examples 1-3

[0055] According to the formula shown in Table 1, the components are mixed evenly to obtain the first liquid and the second liquid of the atomized liquid of Example 1-3, wherein each raw material component is measured by mass percentage. The following tests are carried out on the atomized liquids of Examples 1-3 and Comparative Examples 1-3 using a compartmentalized electronic atomization device with two liquid storage bins. The first liquid and the second liquid of Examples 1-3 are independently stored in the two liquid storage bins of the compartmentalized electronic atomization device. Comparative Example 1 is to mix the first liquid and the second liquid of Example 1 evenly, and then divide them into two parts by mass, and then place the two parts in the two liquid storage bins of the compartmentalized electronic atomization device, that is, the first liquid and the second liquid are not stored independently. Comparative Example 2 is to place the first liquid in Example 1 in the two liquid storage bins of the compartmentalized electronic atomization device at the same time. Comparative Example 3 is to place the second liquid in Example 1 in the two liquid storage bins of the compartmentalized electronic atomization device at the same time.

[0056] Table 1 Weight parts of each component in the atomized liquid of Examples 1-3 and Comparative Examples 1-3

[0057] As shown in Table 1, the e-liquid in both reservoirs of Examples 1-3 was uniformly clear, with each first solute evenly dispersed in its corresponding first solvent, and each second solute evenly dispersed in its corresponding second solvent. Comparative Example 1, in which the originally uniformly clear first and second liquids of Example 1 were mixed, resulted in turbid stratification and the appearance of suspended small droplets.

[0058] Sensory evaluation test

[0059] An evaluation panel consisting of six individuals who had undergone a sensory assessment was selected. Using smoke volume, aroma restoration, aroma richness, sweetness, and consistency as evaluation indicators, a sensory evaluation was conducted on the atomized liquids of Examples 1-3 and Comparative Examples 1-3. To eliminate differences in electronic atomization 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 sweetness of the previous sample completely dissipated.

[0060] Each panelist puffed each of the examples and comparative examples using a full-cycle puff evaluation method. Using a hidden scoring method, the scores of all panelists were averaged for each item in each aerosolized liquid sample, based on the meaning of the four sensory quality evaluation indicators (aerosol volume, aroma reproduction, aroma intensity, and sweetness) in Table 2. Furthermore, if more than half of the six panelists noted poor puff consistency, an off-flavor, or a burnt and bitter taste, the sample was considered to have poor puff consistency and an off-flavor. The sensory evaluation results are shown in Table 3.

[0061] Table 2 Scoring standards for sensory evaluation of electronic atomizing liquid

[0062] Table 3 Sensory evaluation of examples and comparative examples

[0063] Combined with the formulations in Table 1, the data in Table 3 show that in Example 1, the first liquid includes only substances with an n-octanol-water partition coefficient greater than 0.73, and the second liquid includes only substances with an n-octanol-water partition coefficient less than -0.74. This results in a rich and reductive aroma, good taste consistency, no odor, and sufficient smoke production. 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 also achieves 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.

[0064] The two liquid storage tanks in 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 a local high-temperature point, which leads to a higher risk of burning. Since most of the aromatic substances are concentrated in the small droplets, when the non-small droplet area in the atomized liquid is atomized, the taste is not rich and restored enough. The random atomization of the small droplet area and the non-small droplet area leads to inconsistent taste before and after inhalation.

[0065] In Comparative Example 2, both liquid storage tanks contained the first liquid of Example 1. Due to the lack of the second liquid and the lack of Class C solvents, the types of flavoring substances were limited, the aroma reduction was significantly reduced, and the smoke volume was weak. In Comparative Example 3, both liquid storage tanks contained the second liquid of Example 1. Due to the lack of the first liquid, the types of flavoring substances were limited, especially the lack of flavoring substances with an n-octanol-water partition coefficient greater than -0.74, resulting in a very discordant experience.
