[0006] However, in the electronic atomization devices of related technologies, different atomizing liquids are simply mechanically combined with the atomizing part, which cannot give full play to the effect of the atomized liquid and make it difficult to bring users a good vaping experience.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of this application, and are therefore only examples, and should not be used to limit the scope of protection of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0060] In the description of the embodiments of this application, technical terms such as "first," "second," and "third" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0061] An embodiment of this application provides an electronic atomizing device 1. Please refer to Figures 1, 6, 9 to 12. The electronic atomizing device 1 includes a first liquid storage chamber 10, a second liquid storage chamber 20, and an atomizing component 30. The first liquid storage chamber 10 is used to store a first atomizing liquid, which includes flavoring substances.

[0062] The second liquid storage chamber 20 is used to store the second atomizing liquid, which includes aroma substances.

[0063] The atomizing component 30 includes a first atomizing part 31 and a second atomizing part 32. The first atomizing part 31 generates a first aerosol by atomizing a first atomizing liquid, and the second atomizing part 32 generates a second aerosol by atomizing a second atomizing liquid.

[0064] The second aerosol includes second aerosol particles with a particle size of less than 1 μm and a mass fraction of second aerosol particles greater than or equal to 0.3%.

[0065] Specifically, the first liquid storage chamber 10 and the second liquid storage chamber 20 are cavities within the electronic atomizing device 1 used to store atomizing liquid, and the two can store different atomizing liquids.

[0066] The first atomizing liquid contains flavor substances, which may not include or may include a small amount of aroma substances, but compared to aroma substances, the first atomizing liquid mainly contains flavor substances.

[0067] The second atomizing liquid contains aroma substances, which may not contain or may contain a small amount of flavor substances, but compared to flavor substances, the second atomizing liquid mainly contains aroma substances.

[0068] In some embodiments, the first atomizing liquid and the second atomizing liquid may also include other substances.

[0069] For example, the first atomizing liquid also includes active ingredients, which include one or more of the following: benzoic acid nicotine salt, levulinic acid nicotine salt, tartrate nicotine salt, citrate nicotine salt, acetate nicotine salt, oxalate nicotine salt, and nicotine. This improves the taste and flavor of the first atomizing liquid after it is atomized and inhaled.

[0070] For example, the second atomizing liquid also includes active ingredients, such as one or more of benzoic acid nicotine salts, acetylated nicotine salts, tartrate nicotine salts, citrate nicotine salts, acetate nicotine salts, oxalate nicotine salts, and nicotine. This improves the taste and flavor of the second atomizing liquid after it is atomized and inhaled.

[0071] Flavor substances can be perceived by human taste buds and can be classified into substances that produce tastes such as sour, sweet, and cool. Their specific types are not limited.

[0072] For example, the flavoring substance includes one or more of neotame, adventitia, sucralose, acesulfame potassium, glucosyl tartrate, inulin, aspartame, hesperidin dihydrochalcone, neohesperidin dihydrochalcone, naringin dihydrochalcone, WS-3 (cooling agent), WS-5 (cooling agent), WS-12 (cooling agent), WS-14 (cooling agent), WS-23 (cooling agent), WS-25 (cooling agent), and WS-27 (cooling agent).

[0073] Aroma substances are classified as substances that can be transported in the form of aroma molecules after being atomized, thus contributing to aroma and taste. Examples include flavoring substances. Their specific types are not limited.

[0074] For example, the aroma compounds include one or more combinations of ethyl methylvalerate, γ-terpinene, 3-carene, o-cymene, hydroxyacetone, acetic acid, γ-heptanol, hexanoic acid, maltol, diphenyl ether, ethyl maltol, octanoic acid, decanol, triethyl citrate, pinene, ethyl butyrate, 2-methylbutyrate, β-pinene, isoamyl acetate, D-limonene, butyl butyrate, ethyl hexanoate, hexyl acetate, terpinene, leaf ester acetate, n-hexanol, allyl hexanoate, leaf alcohol, ethyl acetoacetate, linalool, linalool acetate, menthol, styrax ester acetate, pineapple ester, phenethyl acetate, benzyl alcohol, phenethyl alcohol, octyl lactone, decanol, peach aldehyde, and methyl dihydrojasmone.

[0075] The atomizing component 30 can heat the first atomizing liquid and the second atomizing liquid to atomize them into an aerosol.

[0076] The first atomizing part 31 and the second atomizing part 32 are different atomizing parts on the atomizing assembly 30. They can be different regions on the same atomizing structure or different atomizing structures that are separate from each other.

[0077] The first atomizing unit 31 heats the first atomizing liquid to atomize it into a first aerosol. The second atomizing unit 32 heats the second atomizing liquid to atomize it into a second aerosol.

[0078] It should be noted that after the aroma substances in the second atomizing liquid are atomized by the second atomizing section 32, more and more concentrated aroma molecules need to be produced. Just as the human body can smell fragrance without direct contact with the aroma liquid or solid, the aroma is better when more aroma molecules are perceived.

[0079] Therefore, by cooperating with the second atomizing unit 32, the mass fraction of second aerosol particles with a particle size of less than 1 μm in the second aerosol can be controlled within a range of greater than or equal to 0.3%, which can greatly improve the aroma concentration of the second aerosol. For example, the mass fraction of the second aerosol particles can be 0.3%, 0.6%, 1%, etc.

[0080] It should be noted that in some embodiments, the particle size of the second aerosol particles is less than 300 nm. That is, a particle size of 300 nm can also be used as a control standard, controlling the mass fraction of second aerosol particles with a particle size less than 300 nm in the second aerosol to be greater than or equal to 0.3%. This can further improve the aroma concentration of the second aerosol.

[0081] The specific method for controlling the mass fraction of the second aerosol particles within the aforementioned range can be set according to actual conditions. For example, by controlling the operating temperature of the second atomizing unit 32, the particle size of the second aerosol generated after the second atomizing liquid is atomized can be changed.

[0082] The detection methods for the particle size and mass of the second aerosol particles are not limited.

[0083] For example, a second aerosol particle with a size smaller than 300 nanometers is detected by a 300 nanometer filter method. The particle size that passes through the 300 nanometer filter is smaller than 300 nanometers (in the gas phase). After passing through the filter, it is collected by a gas bag. The mass collected accounts for 0.3% of the total mass. In fact, the more aroma substances collected by the gas bag, the better.

[0084] The first liquid storage chamber 10 of the electronic atomizing device 1 in this embodiment is used to store a first atomizing liquid, which includes flavor substances. The second liquid storage chamber 20 is used to store a second atomizing liquid, which includes aroma substances. The atomizing component 30 includes a first atomizing section 31 and a second atomizing section 32. The first atomizing section 31 atomizes the first atomizing liquid to generate a first aerosol, and the second atomizing section 32 atomizes the second atomizing liquid to generate a second aerosol. Thus, by using different atomizing sections of the atomizing component 30 to atomize the first and second atomizing liquids respectively, it is convenient to match different atomizing sections according to different types of atomizing liquids, thereby avoiding the problem that it is difficult to achieve a good atomization state for different atomizing liquids when a single atomizing section atomizes different atomizing liquids, thus improving the atomization effect of the electronic atomizing device 1. On the other hand, the second atomizing section 32 atomizes the second atomizing liquid to generate a second aerosol. By controlling the second aerosol generated by the second atomizing section 32, ensuring that the mass fraction of second aerosol particles with a diameter less than 1 μm is greater than or equal to 0.3%, the amount of gaseous aroma substances in the second aerosol can be significantly increased, thereby enhancing the aroma concentration of the second aerosol. Therefore, by controlling the particle size and number of aerosol particles in the second aerosol, the aroma concentration of the second aerosol can be adjusted, thus better utilizing the atomized liquid and providing users with a better inhalation experience.

[0085] In one embodiment, the second atomizing section 32 has a second atomizing surface. The average operating temperature of the second atomizing surface is higher than the azeotropic temperature of the second atomizing liquid, and the temperature difference between the average operating temperature of the second atomizing surface and the azeotropic temperature of the second atomizing liquid is greater than or equal to 10°C and less than or equal to 80°C. Therefore, the mass range of second aerosol particles with a particle size of less than 1 μm can be controlled within a range greater than or equal to 0.3%, thereby enhancing the aroma of the second aerosol after atomization from the second atomizing liquid, and thus further improving the atomization effect of the electronic atomizing device 1.

[0086] In some embodiments, by controlling the temperature difference to a range of greater than or equal to 10°C and less than or equal to 80°C, it is also possible to control the mass range of second aerosol particles with a particle size of less than 300 nm to a range of greater than or equal to 0.3%.

[0087] Specifically, the second atomizing section 32 is matched with the second atomizing liquid, since the second atomizing liquid mainly contains aroma substances.

[0088] Regarding aroma substances, raising the average operating temperature of the second atomizing surface of the second atomizing section 32 above the azeotropic temperature of the second atomizing liquid can stimulate more aroma substances, allowing them to be transported in the form of aroma molecules. The fact that the average operating temperature of the second atomizing surface is higher than the azeotropic temperature of the second atomizing liquid constitutes superheat. Using higher superheat can stimulate more aroma molecules, thus improving the aroma and taste of the aerosol and further enhancing the atomization effect of the electronic atomizing device 1.

[0089] Controlling the temperature difference between the two components within a range of 10°C or higher and 80°C or lower can effectively stimulate the release of more aromatic substances, allowing them to be atomized more in the form of gaseous fragrance molecules. Examples include 10°C, 30°C, 50°C, 60°C, or 80°C.

[0090] It should be noted that the average operating temperature control of the second atomizing surface of the second atomizing section 32 can be achieved by controlling the temperature field.

[0091] In one embodiment, referring to Figure 3, the temperature of the atomizing component 30 is detected using a mixed solvent of PG / VG = 1:1 (azeotropic temperature 250°C). Sample A represents high superheat, with an average operating temperature of the atomizing surface exceeding 250°C. This temperature exceeds the standard by 50°C at a power of 6W and by 100°C at a power of 7W. Similarly, sample B represents medium superheat, and sample C represents low superheat. Superheat is directly related to power; therefore, superheat can be controlled by adjusting the power, with a greater control range for high superheat samples. Superheat is also related to the liquid supply and can be adjusted by regulating the pore size and porosity.

[0092] In one specific embodiment, the temperature difference is greater than or equal to 30°C and less than or equal to 50°C. This allows for better stimulation of aromatic substances, resulting in a better atomization effect of the electronic atomizing device 1.

[0093] In one specific embodiment, for the second atomizing liquid, the release of aroma substances and sensory evaluation were compared under conditions of no superheat and 50°C superheat, and the results are as follows.

[0094] Table 1

[0095] As can be seen from the table above, under the condition of 50℃ superheat, the total amount of gaseous aroma substances is 223.032 μg / puff, which is greater than the total amount of gaseous aroma substances of 123.724 μg / puff under the condition of no superheat.

[0096] Table 2

[0097] In one embodiment, the concentration of flavor substances in the first aerosol is a first concentration, and the concentration of flavor substances in the first atomizing liquid is a second concentration, wherein the first concentration is greater than the second concentration. Therefore, by controlling the concentration of flavor substances in the first aerosol, the atomization effect of the first atomizing liquid can be better utilized, increasing the proportion of flavor substances deposited in the user's mouth, thereby improving the taste.

[0098] Specifically, the control requirements for the atomized aerosol vary depending on the type of atomizing liquid.

[0099] The second aerosol contains aromatic substances. Since the human body does not need to directly contact the liquid or solid aromatic substances, it can perceive the aroma by sensing the gaseous aromatic substances. Therefore, for the second aerosol, it is necessary to control the particle size of the second aerosol to be small enough and the number to be large enough, so as to achieve a large enough mass fraction.

[0100] The first aerosol contains flavor substances. Since the first atomizing liquid mainly consists of flavor substances, these substances need to be contained within larger aerosol particles to be better perceived by human taste buds. Therefore, the higher the concentration of flavor substances in the first aerosol, the more pronounced the perception. When the concentration is insufficient, to raise the threshold for human perception, the number of larger aerosol particles needs to be increased to ensure a high concentration of flavor substances in the first aerosol. This ensures sufficient flavor substances are transported and deposited in the human body, thus improving the taste of the atomized first aerosol.

[0101] It should be noted that the particle size of the aerosol particles in the first aerosol can be determined according to the actual situation.

[0102] For example, the first aerosol includes first aerosol particles with a particle size greater than or equal to 5 μm and less than or equal to 100 μm. Therefore, by forming large-sized first aerosol particles, users can better perceive the flavor compounds within the first aerosol, resulting in a better taste. However, excessive large-particle aerosol can easily cause condensation and leakage, affecting the user experience of the electronic atomizing device 1; therefore, the particle size of the first aerosol particles should not be too large.

[0103] The first concentration is higher than the second concentration, therefore the concentration of flavor substances in the first aerosol formed after atomization is higher than that in the first atomizing liquid. The specific values ​​of the first and second concentrations can be set according to actual conditions.

[0104] For example, the first concentration is greater than or equal to twice the second concentration. Such as 2 times, 3 times, 4 times, etc.

[0105] For example, the first concentration is greater than the second concentration but less than or 5 times the second concentration.

[0106] For example, the first concentration is greater than the second concentration but less than or four times the second concentration. Or, the first concentration is greater than or equal to twice the second concentration but less than or four times the second concentration. This allows the concentration of flavor substances in the first aerosol to be controlled within a certain range, thus better utilizing the effect of the first atomizing liquid and improving the user's inhalation experience.

[0107] The increase in the first concentration can be achieved by setting up the first atomizing section 31.

[0108] For example, the first atomizing unit 31 has a first atomizing surface 311a and an oil storage space 311b. The oil storage space 311b is located on the side of the atomizing assembly 30 with the first atomizing surface 311a. When the first atomizing unit 31 is working, the thickness of the first atomized liquid in the oil storage space 311b is greater than or equal to 10 μm and less than or equal to 200 μm. This allows for a sufficiently high concentration of flavor substances in the first aerosol, while simultaneously increasing the size of the aerosol particles generated by the first atomizing liquid. This increases the proportion of aerosol particles deposited in the oral cavity, enhancing the taste and thus further improving the atomization effect of the electronic atomizing device 1.

[0109] Specifically, the first atomizing surface 311a is the area on the first atomizing section 31 used for heating and atomizing the first atomizing liquid.

[0110] On the same side as the first atomizing surface 311a, an oil storage space 311b is formed, within which an oil film of a certain thickness can be formed. Thus, when the first atomizing unit 31 is working, on the side of the first atomizing surface 311a, the first atomizing unit 31 can atomize the oil film formed by the first atomizing liquid, causing the oil film to undergo processes such as high-temperature evaporation, overheating, and boiling, resulting in oil film breakage and splattering, thereby generating large-size particle aerosols.

[0111] It is understandable that the flavor compounds in the first atomizing liquid need to be contained within larger aerosol particles to be better perceived by the human taste buds. Therefore, more and larger aerosol particles are an important condition for flavor compounds. Simultaneously, the concentration of flavor compounds within more and larger aerosol particles also affects their perception by the human body. Therefore, by forming an oil storage space 311b to limit the thickness of the first atomizing liquid to a range greater than or equal to 10 μm and less than or equal to 200 μm, the first atomizing section 31 can generate more and larger aerosol particles, resulting in a higher concentration of flavor compounds in the aerosols, thus improving the taste and atomization effect. For example, the thickness of the first atomizing liquid can be 10 μm, 30 μm, 60 μm, 100 μm, 150 μm, or 200 μm.

[0112] It should be noted that, in some embodiments, the thickness of the first atomizing liquid within the oil storage space 311b is greater than or equal to 30 μm and less than or equal to 100 μm. By controlling the size of the oil storage space 311b to ensure that the thickness of the first atomizing liquid within the oil storage space 311b is within the aforementioned range, it is possible to better promote the generation of large aerosol particles and further improve the atomization effect.

[0113] In fact, the thickness of the first atomizing liquid in the oil storage space 311b can be determined based on the depth of the oil storage space 311b.

[0114] For example, when the oil supply is sufficient, due to the combined effects of surface tension and capillary force, the oil film will be roughly equivalent to the depth of the oil storage space 311b. In a static state, the height difference between the surface oil film and the oil storage space 311b is observed using a high-precision microscope to determine the oil film thickness. During atomization, a high-speed camera is used to observe whether the surface oil film of the first atomizing section 31 is sufficient. Therefore, the depth of the oil storage space 311b corresponding to the required thickness of the first atomized liquid can be comprehensively determined.

[0115] It should be noted that the oil storage space 311b is a microstructure that temporarily stores atomizing liquid to form an oil film and supply liquid to the first atomizing surface 311a. For example, the oil storage space 311b includes one or a combination of a liquid storage tank and an oil storage hole.

[0116] For example, the oil storage space 311b is formed by a structure with a porous layer.

[0117] By employing simultaneous compartmentalized atomization technology with different atomizing units, the atomizing units can be matched with the characteristics of the atomizing liquid in the storage chamber, thereby generating specific atomization conditions and stimulating the optimal atomization state of different media. Consequently, the different components in the media are characterized and atomized under optimal atomization conditions, better stimulating the transport and release of different components. Finally, by controlling the transport and release of different components, such as aerosol particle size, quantity, concentration, and temperature, differentiated flavors and optimal taste can be achieved.

[0118] In one embodiment, please refer to Figure 2. For the first atomizing liquid, the amount of sweet substances released and the sensory evaluation comparison for large droplets of different sizes are shown in the table below.

[0119] Table 3

[0120] The specific type of atomizing component 30 can be determined according to the actual situation.

[0121] In one embodiment, the atomizing component 30 is one or more combinations of a porous substrate thick film heating element, a porous substrate mesh heating element, and a dense through-pore substrate thin film heating element. This facilitates the atomizing component 30 in atomizing the first and second atomizing liquids.

[0122] In one embodiment, referring to Figures 6 and 7, the first atomizing part 31 includes a first substrate 311, a heating element 312, and an oil film limiting structure 313. The first substrate 311 has a first atomizing surface 311a, the heating element 312 is disposed on the first atomizing surface 311a, and the oil film limiting structure 313 has an oil storage space 311b and is disposed on the outer surface of the heating element 312.

[0123] Therefore, the formation of the oil film of the first atomizing liquid can be achieved through additive manufacturing, which can better realize the generation of large-particle aerosols and thus improve the atomization effect.

[0124] Specifically, the oil film confinement structure 313 refers to a structure that can form an oil film of a set thickness by confining the first atomizing liquid. This could be a structure with a porous surface layer or a surface microstructure. The heating element 312 can be any structure capable of heating the atomizing liquid to atomize it, such as a heating film.

[0125] In one specific embodiment, as shown in Figures 6 and 7, the first atomizing part 31 includes a porous substrate (i.e., the first substrate 311), a heating element 312, and a porous thin layer (i.e., an oil film confinement structure 313). The porous substrate includes a first liquid absorption surface and a first atomizing surface 311a. The heating element 312 is located on the first atomizing surface 311a. The porous thin layer covers at least a portion of the outer surface of the heating element 312. The porous thin layer forms an oil storage space 311b located on one side of the first atomizing surface 311a.

[0126] It should be noted that the thickness of the porous thin layer can be set according to actual conditions. For example, the thickness of the porous thin layer can be greater than or equal to 10 μm and less than or equal to 200 μm. Examples include 10 μm, 50 μm, 100 μm, 150 μm, or 200 μm. Controlling the thickness of the porous thin layer within this range facilitates the formation of an oil film, thereby better enabling the generation of large-particle aerosols and improving the atomization effect.

[0127] The specific material of the porous thin layer is not limited. For example, porous thin layers include, but are not limited to, porous ceramic layers, porous glass layers, or fiber layers.

[0128] In one embodiment, referring to Figures 8 and 9, the first atomizing part 31 includes a first substrate 311 and a heating element 312. The first substrate 311 has a first atomizing surface 311a. A portion of the first atomizing surface 311a is recessed to form an oil storage space 311b. The heating element 312 is disposed in the oil storage space 311b, and the thickness of at least a portion of the heating element 312 is lower than the depth of the oil storage space 311b.

[0129] Therefore, during the heating process of the heating element 312, the oil film of the first atomizing liquid in the oil storage space 311b can be atomized, which can realize the generation of large particle aerosols and thus improve the atomization effect.

[0130] Specifically, the first substrate 311 forms an oil storage space 311b by means of subtraction to achieve the formation of an oil film of the first atomized liquid. The heating element 312 is placed in the oil storage space 311b, which facilitates better heating of the heating element 312.

[0131] The heating element 312 may have a thickness that is lower than the depth of the oil storage space 311b in only a part of its area, or the thickness of the entire area may be lower than the depth of the oil storage space 311b. Thus, the height difference between the two can facilitate better storage of atomizing liquid to form an oil film.

[0132] In another specific embodiment, as shown in Figures 8 and 9, the first substrate 311 is a porous substrate, and the first atomizing surface 311a forms a capillary groove corresponding to the shape of the heating element 312. The heating element 312 is located in the capillary groove and its top is lower than the opening of the capillary groove, thereby forming an oil storage space 311b for forming an oil film.

[0133] The specific dimensions of the height difference between the heating element and the capillary groove opening can be set according to actual conditions. For example, the height difference between the two can be greater than or equal to 10μm and less than or equal to 200μm. Examples include 10μm, 50μm, 100μm, 150μm, or 200μm. Controlling the height difference within the above range facilitates the formation of an oil film, thereby better achieving the generation of large-particle aerosols and improving the atomization effect.

[0134] In one embodiment, by setting the thickness of the first atomizing liquid within the oil storage space 311b to a range greater than or equal to 30 μm and less than or equal to 100 μm, the first atomizing section 31 atomizes the first atomizing liquid to produce large-diameter aerosol particles with a particle size greater than or equal to 5 μm and less than or equal to 100 μm. This effectively improves the user's inhalation experience. Examples of particle sizes include 5 μm, 10 μm, 25 μm, 50 μm, or 100 μm.

[0135] For example, by limiting the thickness of the first atomizing liquid in the oil storage space 311b, the particle size of the large-diameter aerosol particles generated by the first atomizing section 31 atomizing the first atomizing liquid is greater than or equal to 10 μm and less than or equal to 50 μm, thereby further improving the user's inhalation experience. For example, 10 μm, 25 μm, or 50 μm.

[0136] For example, by limiting the thickness of the first atomizing liquid within the oil storage space 311b, the first atomizing section 31 atomizes the first atomizing liquid to generate a larger amount of aerosol, with the aerosol accounting for 3% to 15% of the total mass of the smoke. This can effectively improve the user's vaping experience. For example, 3%, 5%, 10%, or 15%.

[0137] For example, by limiting the thickness of the first atomizing liquid within the oil storage space 311b, the first atomizing section 31 atomizes the first atomizing liquid to generate a larger amount of aerosol, which accounts for 5% to 10% of the total mass of the smoke, thereby further improving the user's vaping experience. For example, 5%, 7%, 8%, or 10%.

[0138] In one embodiment, the electronic atomizing device 1 includes a first atomizer and a second atomizer. The first atomizer includes a first atomizing section 31, and the second atomizer includes a second atomizing section 32. That is, the first liquid storage tank 10 and the second liquid storage tank 20 each correspond to a separate atomizer. In practice, the two atomizers can share a single air outlet channel, so that the aerosol generated by either atomizer can easily flow out of the electronic atomizing device 1 when either atomizer is in operation.

[0139] Of course, depending on the actual situation, the atomizing component 30 can also be configured in other ways.

[0140] For example, referring to Figures 10 to 12, the atomizing assembly 30 includes a first heating element structure, which includes a first atomizing section 31. The atomizing assembly 30 also includes a second heating element structure, which includes a second atomizing section 32. The first heating element structure and the second heating element structure are disposed within the housing of the same atomizer.

[0141] For example, the atomizing component 30 includes a heating substrate, a first heating element, and a second heating element. The heating substrate includes a first liquid supply area and a second liquid supply area that are separated from each other. The first heating element and the first liquid supply area together constitute a first atomizing part 31, and the second heating element and the second liquid supply area together constitute a second atomizing part 32. The first liquid supply area is connected to the first liquid storage chamber 10 and has a first atomizing surface 311a. The second liquid supply area is connected to the second liquid storage chamber 20 and has a second atomizing surface. The first heating element is disposed on the first atomizing surface 311a, and the second heating element is disposed on the second atomizing surface.

[0142] In other words, the first atomizing section 31 and the second atomizing section 32 are integrated into one unit. Specifically, the first atomizing section 31 includes a first heating element and a first liquid supply area, and the second atomizing section 32 includes a second heating element and a second liquid supply area. The first liquid supply area and the second liquid supply area are different regions on the same heating substrate. The first liquid supply area is used to supply the first atomizing liquid to the first heating element, while the second liquid supply area is used to supply the second atomizing liquid to the second heating element.

[0143] The first and second liquid supply zones are separated from each other and are not connected. The first and second heating elements are also independent. This simplifies the internal structure of the electronic atomizing device 1, making it more compact.

[0144] It should be noted that there are no restrictions on the specific implementation method for separating the first liquid supply area and the second liquid supply area.

[0145] For example, the first and second liquid supply zones are separated by silicone, and the fluid is not interconnected with the dual liquid storage tanks.

[0146] For example, physical isolation grooves and protrusions can be provided between the first liquid supply zone and the second liquid supply zone to isolate different fluids.

[0147] In addition, the same heating circuit can be used to supply power and heat the first atomizing section 31 and the second atomizing section 32, or different heating circuits can be used to supply power and heat the first atomizing section 31 and the second atomizing section 32.

[0148] In one embodiment, the electronic atomizing device 1 includes a housing assembly having an air inlet and an air outlet, and an airflow path passing through at least one of the first atomizing section 31 and the second atomizing section 32 is formed between the air inlet and the air outlet.

[0149] When the first atomizing section 31 is operational, the airflow path passes through the first atomizing section 31, causing the first aerosol to mix with the airflow from the air inlet to form a mixed gas that flows out from the air outlet. The mass of the first aerosol in the mixed gas is greater than or equal to 3% and less than or equal to 15% of the mass of the mixed gas. This ensures that the concentration of the first aerosol in the mixed gas flowing out from the air outlet is sufficiently high to be well perceived by the human body, greatly improving the user's inhalation experience.

[0150] Specifically, the air inlet of the housing assembly is used to allow external airflow to enter, and the air outlet is used to allow the mixed airflow to exit. After the external airflow enters through the air inlet, it passes through the atomizing assembly 30 and flows out through the air outlet.

[0151] According to the specific operation of the first atomizing section 31 and the second atomizing section 32, when the first atomizing section 31 is working, the external airflow flows out from the air outlet after passing through the first atomizing section 31. When the second atomizing section 32 is working, the external airflow flows out from the air outlet after passing through the second atomizing section 32.

[0152] In one embodiment, the first atomizing liquid further includes a highly polar solvent, which includes one or more of water, ethylene glycol, glycerol, and glycerol.

[0153] Specifically, highly polar solvents can dissolve highly polar substances, such as neotame, adventitia, sucralose, menthol, menthyl ether, menthyl ester, nicotine benzoate, nicotine levulinate, nicotine tartrate, nicotine citrate, nicotine acetate, and nicotine oxalate. Highly polar solvents can better match flavor compounds, thereby reducing the likelihood of poor miscibility (or low solubility) due to significant differences in physical properties. This reduces solubility bottlenecks in media preparation, avoids oil floating and stratification caused by poor media miscibility in single-compartment atomization, and ensures complete atomization of the media.

[0154] In one embodiment, the second atomizing liquid further includes a low-polarity solvent, which includes one or more of ethanol, propanol, butanol, and benzyl alcohol.

[0155] Specifically, low-polarity solvents can dissolve low-polarity substances such as sweet orange oil, bitter almond oil, bitter orange oil, cardamom oil, cinnamon oil, and clove oil. Low-polarity solvents can better match aroma compounds, thereby reducing the likelihood of poor miscibility (or low solubility) due to significant differences in physical properties. This reduces solubility bottlenecks in media preparation, avoids oil floating and stratification caused by poor media miscibility in single-compartment atomization, and ensures complete atomization of the media.

[0156] In one embodiment, referring to Figures 4 and 5, neotame is a representative flavor substance, and the transmission rate is the ratio of the sweetener concentration (flavor substance concentration) in the first aerosol to the sweetener concentration in the first nebulizing liquid. Specifically, Sample A (80%) < Sample B (180%) < Sample C (270%), indicating that higher concentrations mean a greater amount of sweetener in the aerosol. Sample A (0.2 μg / puff) < Sample B (0.4 μg / puff) < Sample C (0.5 μg / puff).

[0157] An embodiment of this application provides an electronic atomizing device 1. Please refer to Figures 1, 6, 9 to 12. The electronic atomizing device 1 includes a first liquid storage chamber 10 and a second liquid storage chamber 20.

[0158] The first liquid storage chamber 10 is used to store the first atomizing liquid, which includes flavoring substances.

[0159] The second liquid storage chamber 20 is used to store the second atomizing liquid, which includes aroma substances.

[0160] The atomizing component 30 includes a first atomizing part 31 and a second atomizing part 32. The first atomizing part 31 is used to atomize a first atomizing liquid, and the second atomizing part 32 is used to atomize a second atomizing liquid.

[0161] The first atomizing part 31 has a first atomizing surface 311a and an oil storage space 311b. The oil storage space 311b is located on the side of the atomizing component 30 with the first atomizing surface 311a. When the first atomizing part 31 is working, the thickness of the first atomized liquid in the oil storage space 311b is greater than or equal to 10μm and less than or equal to 200μm.

[0162] Specifically, the first liquid storage chamber 10 and the second liquid storage chamber 20 are cavities within the electronic atomizing device 1 used to store atomized liquid, and the two can store different atomized liquids.

[0163] The first atomizing liquid contains flavor substances, which may not include or may include a small amount of aroma substances, but compared to aroma substances, the first atomizing liquid mainly contains flavor substances.

[0164] The second atomizing liquid contains aroma substances, and may not contain or may contain a small amount of flavor substances. However, compared to flavor substances, the first atomizing liquid mainly contains aroma substances.

[0165] In some embodiments, the first atomizing liquid and the second atomizing liquid may also include other substances.

[0166] For example, the first atomizing liquid also includes active ingredients, which include one or more of the following: benzoic acid nicotine salt, levulinic acid nicotine salt, tartrate nicotine salt, citrate nicotine salt, acetate nicotine salt, oxalate nicotine salt, and nicotine. This improves the taste and flavor of the first atomizing liquid after it is atomized and inhaled.

[0167] For example, the second atomizing liquid also includes active ingredients, such as one or more of benzoic acid nicotine salts, acetylated nicotine salts, tartrate nicotine salts, citrate nicotine salts, acetate nicotine salts, oxalate nicotine salts, and nicotine. This improves the taste and flavor of the second atomizing liquid after it is atomized and inhaled.

[0168] Flavor substances can be perceived by human taste buds and can be classified into substances that produce tastes such as sour, sweet, and cool. Their specific types are not limited.

[0169] For example, the flavoring substance includes one or more of neotame, adventitia, sucralose, acesulfame potassium, glucosyl tartrate, inulin, aspartame, hesperidin dihydrochalcone, neohesperidin dihydrochalcone, naringin dihydrochalcone, WS-3 (cooling agent), WS-5 (cooling agent), WS-12 (cooling agent), WS-14 (cooling agent), WS-23 (cooling agent), WS-25 (cooling agent), and WS-27 (cooling agent).

[0170] Aroma substances are classified as substances that can be transported in the form of aroma molecules after being atomized, thus contributing to aroma and taste. Examples include flavoring substances. Their specific types are not limited.

[0171] For example, the aroma compounds include one or more combinations of ethyl methylvalerate, γ-terpinene, 3-carene, o-cymene, hydroxyacetone, acetic acid, γ-heptanol, hexanoic acid, maltol, diphenyl ether, ethyl maltol, octanoic acid, decanol, triethyl citrate, pinene, ethyl butyrate, 2-methylbutyrate, β-pinene, isoamyl acetate, D-limonene, butyl butyrate, ethyl hexanoate, hexyl acetate, terpinene, leaf ester acetate, n-hexanol, allyl hexanoate, leaf alcohol, ethyl acetoacetate, linalool, linalool acetate, menthol, styrax ester acetate, pineapple ester, phenethyl acetate, benzyl alcohol, phenethyl alcohol, octyl lactone, decanol, peach aldehyde, and methyl dihydrojasmone.

[0172] The atomizing component 30 can heat the first atomizing liquid and the second atomizing liquid to atomize them into an aerosol.

[0173] The first atomizing part 31 and the second atomizing part 32 are different atomizing parts on the atomizing assembly 30. They can be different regions on the same atomizing structure or different atomizing structures that are separate from each other.

[0174] The first atomizing unit 31 atomizes the first atomizing liquid into an aerosol by heating it. The second atomizing unit 32 atomizes the second atomizing liquid into an aerosol by heating it.

[0175] The first atomizing surface 311a is the area on the first atomizing part 31 used to heat and atomize the first atomizing liquid.

[0176] On the same side as the first atomizing surface 311a, an oil storage space 311b is formed, within which an oil film of a certain thickness can be formed. Thus, when the first atomizing unit 31 is working, on the side of the first atomizing surface 311a, the first atomizing unit 31 can atomize the oil film formed by the first atomizing liquid, causing the oil film to undergo processes such as high-temperature evaporation, overheating, and boiling, resulting in oil film breakage and splattering, thereby generating large-size particle aerosols.

[0177] It is understandable that the flavor compounds in the first atomizing liquid need to be contained within larger aerosol particles to be better perceived by the human taste buds. Therefore, more and larger aerosol particles are an important condition for flavor compounds. Simultaneously, the concentration of flavor compounds within more and larger aerosol particles also affects their perception by the human body. Therefore, by forming an oil storage space 311b to limit the thickness of the first atomizing liquid to a range greater than or equal to 10 μm and less than or equal to 200 μm, the first atomizing section 31 can generate more and larger aerosol particles, resulting in a higher concentration of flavor compounds in the aerosols, thus improving the taste and atomization effect. For example, the thickness of the first atomizing liquid can be 10 μm, 30 μm, 60 μm, 100 μm, 150 μm, or 200 μm.

[0178] It should be noted that, in some embodiments, the thickness of the first atomizing liquid within the oil storage space 311b is greater than or equal to 30 μm and less than or equal to 100 μm. By controlling the size of the oil storage space 311b to ensure that the thickness of the first atomizing liquid within the oil storage space 311b is within the aforementioned range, it is possible to better promote the generation of large aerosol particles and further improve the atomization effect.

[0179] In fact, the thickness of the first atomizing liquid in the oil storage space 311b can be determined based on the depth of the oil storage space 311b.

[0180] For example, when the oil supply is sufficient, due to the combined effects of surface tension and capillary force, the oil film will be roughly equivalent to the depth of the oil storage space 311b. In a static state, the height difference between the surface oil film and the oil storage space 311b is observed using a high-precision microscope to determine the oil film thickness. During atomization, a high-speed camera is used to observe whether the surface oil film of the first atomizing section 31 is sufficient. Therefore, the depth of the oil storage space 311b corresponding to the required thickness of the first atomized liquid can be comprehensively determined.

[0181] It should be noted that the oil storage space 311b is a microstructure that temporarily stores atomizing liquid to form an oil film and supply liquid to the first atomizing surface 311a. For example, the oil storage space 311b includes one or a combination of a liquid storage tank and an oil storage hole.

[0182] For example, the oil storage space 311b is formed by a structure with a porous layer.

[0183] The electronic atomizing device 1 of this application embodiment includes a first liquid storage chamber 10, a second liquid storage chamber 20, and an atomizing component 30. The first liquid storage chamber 10 is used to store a first atomizing liquid, which includes flavor substances. The second liquid storage chamber 20 is used to store a second atomizing liquid, which includes aroma substances. The atomizing component 30 includes a first atomizing section 31 and a second atomizing section 32. The first atomizing section 31 is used to atomize the first atomizing liquid, and the second atomizing section 32 is used to atomize the second atomizing liquid. The first atomizing section 31 has a first atomizing surface 311a and an oil storage space 311b. The oil storage space 311b is located on the side of the atomizing component 30 with the first atomizing surface 311a. When the first atomizing section 31 is working, the thickness of the first atomizing liquid in the oil storage space 311b is greater than or equal to 10 μm and less than or equal to 200 μm. On the one hand, by using different atomizing sections of the atomizing component 30 to atomize the first and second atomizing liquids respectively, it is easy to match different atomizing sections according to different types of atomizing liquids. This avoids the problem that it is difficult to achieve a good atomization state for different atomizing liquids when a single atomizing section atomizes different atomizing liquids, thus improving the atomization effect of the electronic atomizing device 1. On the other hand, the first liquid storage chamber 10 is used to store the first atomizing liquid containing flavor substances. Specifically, by setting the thickness of the first atomizing liquid in the oil storage space 311b within the range of 10μm to 200μm, the size of the aerosol particles generated by the first atomizing liquid can be increased, thereby increasing the proportion of aerosol particles deposited in the oral cavity, improving the taste, and thus further improving the atomization effect of the electronic atomizing device 1.

[0184] By employing simultaneous compartmentalized atomization technology with different atomizing units, the atomizing units can be matched with the characteristics of the atomizing liquid in the storage chamber, thereby generating specific atomization conditions and stimulating the optimal atomization state of different media. Consequently, the different components in the media are characterized and atomized under optimal atomization conditions, better stimulating the transport and release of different components. Finally, by controlling the transport and release of different components, such as aerosol particle size, quantity, concentration, and temperature, differentiated flavors and optimal taste can be achieved.

[0185] In one embodiment, the second atomizing section 32 has a second atomizing surface. The average operating temperature of the second atomizing surface is higher than the azeotropic temperature of the second atomizing liquid, and the temperature difference between the average operating temperature of the second atomizing surface and the azeotropic temperature of the second atomizing liquid is greater than or equal to 10°C and less than or equal to 80°C. This enhances the aroma of the aerosol atomized from the second atomizing liquid, thereby further improving the atomization effect of the electronic atomizing device 1.

[0186] Specifically, the second atomizing section 32 is matched with the second atomizing liquid, since the second atomizing liquid mainly contains aroma substances.

[0187] Regarding aroma substances, raising the average operating temperature of the second atomizing surface of the second atomizing section 32 above the azeotropic temperature of the second atomizing liquid can stimulate more aroma substances, allowing them to be transported in the form of aroma molecules. The fact that the average operating temperature of the second atomizing surface is higher than the azeotropic temperature of the second atomizing liquid constitutes superheat. Using higher superheat can stimulate more aroma molecules, thus improving the aroma and taste of the aerosol and further enhancing the atomization effect of the electronic atomizing device 1.

[0188] Controlling the temperature difference between the two components within a range of 10°C or higher and 80°C or lower can effectively stimulate the release of more aromatic substances, allowing them to be atomized more in the form of gaseous fragrance molecules. Examples include 10°C, 30°C, 50°C, 60°C, or 80°C.

[0189] It should be noted that the average operating temperature control of the second atomizing surface of the second atomizing section 32 can be achieved by controlling the temperature field.

[0190] In one embodiment, referring to Figure 3, the temperature of the atomizing component 30 was measured using a PG / VG mixed solvent of 1:1 (azeotropic temperature 250°C). Sample A represents high superheat, with an average operating temperature of the atomizing surface exceeding 250°C. This temperature exceeds the standard by 50°C at a power of 6W and by 100°C at a power of 7W. Similarly, sample B represents medium superheat, and sample C represents low superheat. Superheat is directly related to power; therefore, it can be seen that superheat can be controlled by controlling the power, with a greater control range for samples with high superheat.

[0191] In one specific embodiment, the temperature difference is greater than or equal to 30°C and less than or equal to 50°C. This allows for better stimulation of aromatic substances, resulting in a better atomization effect of the electronic atomizing device 1.

[0192] In one specific embodiment, for the second atomizing liquid, the release of aroma substances and sensory evaluation were compared under conditions of no superheat and 50°C superheat, and the results are as follows.

[0196] In one embodiment, please refer to Figure 2. For the first atomizing liquid, the amount of sweet substances released and the sensory evaluation comparison for large droplets of different sizes are shown in the table below.

[0197] Table 6

[0198] The specific type of atomizing component 30 can be determined according to the actual situation.

[0199] In one embodiment, the atomizing component 30 is one or more combinations of a porous substrate thick film heating element, a porous substrate mesh heating element, and a dense through-pore substrate thin film heating element. This facilitates the atomizing component 30 in atomizing the first and second atomizing liquids.

[0200] In one embodiment, referring to Figures 6 and 7, the first atomizing part 31 includes a first substrate 311, a heating element 312, and an oil film limiting structure 313. The first substrate 311 has a first atomizing surface 311a, the heating element 312 is disposed on the first atomizing surface 311a, and the oil film limiting structure 313 has an oil storage space 311b and is disposed on the outer surface of the heating element 312.

[0201] Therefore, the formation of the oil film of the first atomizing liquid can be achieved through additive manufacturing, which can better realize the generation of large-particle aerosols and thus improve the atomization effect.

[0202] Specifically, the oil film confinement structure 313 refers to a structure that can form an oil film of a set thickness by confining the first atomizing liquid. This could be a structure with a porous surface layer or a surface microstructure. The heating element 312 can be any structure capable of heating the atomizing liquid to atomize it, such as a heating film.

[0203] In one specific embodiment, as shown in Figures 6 and 7, the first atomizing part 31 includes a porous substrate (i.e., the first substrate 311), a heating element 312, and a porous thin layer (i.e., an oil film confinement structure 313). The porous substrate includes a first liquid absorption surface and a first atomizing surface 311a. The heating element 312 is located on the first atomizing surface 311a. The porous thin layer covers at least a portion of the outer surface of the heating element 312. The porous thin layer forms an oil storage space 311b located on one side of the first atomizing surface 311a.

[0204] It should be noted that the thickness of the porous thin layer can be set according to actual conditions. For example, the thickness of the porous thin layer can be greater than or equal to 10 μm and less than or equal to 200 μm. Examples include 10 μm, 50 μm, 100 μm, 150 μm, or 200 μm. Controlling the thickness of the porous thin layer within this range facilitates the formation of an oil film, thereby better enabling the generation of large-particle aerosols and improving the atomization effect.

[0205] The specific material of the porous thin layer is not limited. For example, porous thin layers include, but are not limited to, porous ceramic layers, porous glass layers, or fiber layers.

[0206] In one embodiment, referring to Figures 8 and 9, the first atomizing part 31 includes a first substrate 311 and a heating element 312. The first substrate 311 has a first atomizing surface 311a. A portion of the first atomizing surface 311a is recessed to form an oil storage space 311b. The heating element 312 is disposed in the oil storage space 311b, and the thickness of at least a portion of the heating element 312 is lower than the depth of the oil storage space 311b.

[0207] Therefore, during the heating process of the heating element 312, the oil film of the first atomizing liquid in the oil storage space 311b can be atomized, which can realize the generation of large particle aerosols and thus improve the atomization effect.

[0208] Specifically, the first substrate 311 forms an oil storage space 311b by means of subtraction to achieve the formation of an oil film of the first atomized liquid. The heating element 312 is placed in the oil storage space 311b, which facilitates better heating of the heating element 312.

[0209] The heating element 312 may have a thickness that is lower than the depth of the oil storage space 311b in only a part of its area, or the thickness of the entire area may be lower than the depth of the oil storage space 311b. Thus, the height difference between the two can facilitate better storage of atomizing liquid to form an oil film.

[0210] In another specific embodiment, as shown in Figures 7 and 9, the first substrate 311 is a porous substrate, and the first atomizing surface 311a forms a capillary groove corresponding to the shape of the heating element 312. The heating element 312 is located in the capillary groove and its top is lower than the opening of the capillary groove, thereby forming an oil storage space 311b for forming an oil film.

[0211] The specific dimensions of the height difference between the heating element and the capillary groove opening can be set according to actual conditions. For example, the height difference between the two can be greater than or equal to 10μm and less than or equal to 200μm. Examples include 10μm, 50μm, 100μm, 150μm, or 200μm. Controlling the height difference within the above range facilitates the formation of an oil film, thereby better achieving the generation of large-particle aerosols and improving the atomization effect.

[0212] In one embodiment, by setting the thickness of the first atomizing liquid within the oil storage space 311b to a range greater than or equal to 30 μm and less than or equal to 100 μm, the first atomizing section 31 atomizes the first atomizing liquid to produce large-diameter aerosol particles with a particle size greater than or equal to 5 μm and less than or equal to 100 μm. This effectively improves the user's inhalation experience. Examples of particle sizes include 5 μm, 10 μm, 25 μm, 50 μm, or 100 μm.

[0213] For example, by limiting the thickness of the first atomizing liquid in the oil storage space 311b, the particle size of the large-diameter aerosol particles generated by the first atomizing section 31 atomizing the first atomizing liquid is greater than or equal to 10 μm and less than or equal to 50 μm, thereby further improving the user's inhalation experience. For example, 10 μm, 25 μm, or 50 μm.

[0214] For example, by limiting the thickness of the first atomizing liquid within the oil storage space 311b, the first atomizing section 31 atomizes the first atomizing liquid to generate a larger amount of aerosol, with the aerosol accounting for 3% to 15% of the total mass of the smoke. This can effectively improve the user's vaping experience. For example, 3%, 5%, 10%, or 15%.

[0215] For example, by limiting the thickness of the first atomizing liquid within the oil storage space 311b, the first atomizing section 31 atomizes the first atomizing liquid to generate a larger amount of aerosol, which accounts for 5% to 10% of the total mass of the smoke, thereby further improving the user's vaping experience. For example, 5%, 7%, 8%, or 10%.

[0216] In one embodiment, the electronic atomizing device 1 includes a first atomizer and a second atomizer. The first atomizer includes a first atomizing section 31, and the second atomizer includes a second atomizing section 32. That is, the first liquid storage tank 10 and the second liquid storage tank 20 each correspond to a separate atomizer. In practice, the two atomizers can share a single air outlet channel, so that the aerosol generated by either atomizer can easily flow out of the electronic atomizing device 1 when either atomizer is in operation.

[0217] Of course, depending on the actual situation, the atomizing component 30 can also be configured in other ways.

[0218] For example, referring to Figures 10 to 12, the atomizing assembly 30 includes a first heating element structure, which includes a first atomizing section 31. The atomizing assembly 30 also includes a second heating element structure, which includes a second atomizing section 32. The first heating element structure and the second heating element structure are disposed within the housing of the same atomizer.

[0219] For example, the atomizing component 30 includes a heating substrate, a first heating element, and a second heating element. The heating substrate includes a first liquid supply area and a second liquid supply area that are separated from each other. The first heating element and the first liquid supply area together constitute a first atomizing part 31, and the second heating element and the second liquid supply area together constitute a second atomizing part 32. The first liquid supply area is connected to the first liquid storage chamber 10 and has a first atomizing surface 311a. The second liquid supply area is connected to the second liquid storage chamber 20 and has a second atomizing surface. The first heating element is disposed on the first atomizing surface 311a, and the second heating element is disposed on the second atomizing surface.

[0220] In other words, the first atomizing section 31 and the second atomizing section 32 are integrated into one unit. Specifically, the first atomizing section 31 includes a first heating element and a first liquid supply area, and the second atomizing section 32 includes a second heating element and a second liquid supply area. The first liquid supply area and the second liquid supply area are different regions on the same heating substrate. The first liquid supply area is used to supply the first atomizing liquid to the first heating element, while the second liquid supply area is used to supply the second atomizing liquid to the second heating element.

[0221] The first and second liquid supply zones are separated from each other and are not connected. The first and second heating elements are also independent. This simplifies the internal structure of the electronic atomizing device 1, making it more compact.

[0222] It should be noted that there are no restrictions on the specific implementation method for separating the first liquid supply area and the second liquid supply area.

[0223] For example, the first and second liquid supply zones are separated by silicone, and the fluid is not interconnected with the dual liquid storage tanks.

[0224] For example, physical isolation grooves and protrusions can be provided between the first liquid supply zone and the second liquid supply zone to isolate different fluids.

[0225] In addition, the same heating circuit can be used to supply power and heat the first atomizing section 31 and the second atomizing section 32, or different heating circuits can be used to supply power and heat the first atomizing section 31 and the second atomizing section 32.

[0226] In one embodiment, the first atomizing liquid further includes a highly polar solvent, which includes one or more of water, ethylene glycol, glycerol, and glycerol.

[0227] Specifically, highly polar solvents can dissolve highly polar substances, such as neotame, adventitia, sucralose, menthol, menthyl ether, menthyl ester, nicotine benzoate, nicotine levulinate, nicotine tartrate, nicotine citrate, nicotine acetate, and nicotine oxalate. Highly polar solvents can better match flavor compounds, thereby reducing the likelihood of poor miscibility (or low solubility) due to significant differences in physical properties. This reduces solubility bottlenecks in media preparation, avoids oil floating and stratification caused by poor media miscibility in single-compartment atomization, and ensures complete atomization of the media.

[0228] In one embodiment, the second atomizing liquid further includes a low-polarity solvent, which includes one or more of ethanol, propanol, butanol, and benzyl alcohol.

[0229] Specifically, low-polarity solvents can dissolve low-polarity substances such as sweet orange oil, bitter almond oil, bitter orange oil, cardamom oil, cinnamon oil, and clove oil. Low-polarity solvents can better match aroma compounds, thereby reducing the likelihood of poor miscibility (or low solubility) due to significant differences in physical properties. This reduces solubility bottlenecks in media preparation, avoids oil floating and stratification caused by poor media miscibility in single-compartment atomization, and ensures complete atomization of the media.
