[0023] In order to more clearly illustrate the technical solutions in the implementation modes of the present application, the drawings required for use in the implementation modes of the present application will be described below.

[0024] Figure 1 A physical picture of an aerosol substrate provided in accordance with one embodiment of the present application.

[0025] Figure 2 The process flow chart of the method for preparing an aerosol substrate in one embodiment of the present application. DETAILED DESCRIPTION

[0026] The following are preferred implementations of the present application. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications are also considered to be within the scope of protection of the present application.

[0027] Heat Not Burning (HNB) is a new product that combines a heating device and a cigarette cartridge or a plant core that does not contain tobacco. It is a low-temperature cigarette technology designed with the idea of ​​"heating without burning". A special heating device is used to heat the processed smoking segment to a certain temperature, and the smoking segment is heated to a degree sufficient to emit smoke (aerosol) for people to smoke. Compared with traditional cigarettes, this low-temperature heating technology generally uses a heating temperature below 350°C for heat-not-burn products, which reduces a lot of harmful substances and restores the pure taste and throat hit of traditional cigarettes, providing smokers with the most similar alternative to traditional cigarettes. This heat-not-burn product, which integrates modern low-temperature atomization technology and the concept of healthy living, firmly grasps the psychological characteristics of consumers and has attracted the attention of many consumers who want to quit smoking in a short period of time.

[0028] Generally speaking, the technology of heat-not-burn smoking can be divided into two mainstreams, namely, thin-sheet technology and particle technology. The use of traditional tobacco leaves for filling has gradually matured. Based on the smoke-free characteristics and low tar hazards of heat-not-burn products, more and more smokers are willing to accept heat-not-burn products HNB to quit smoking. At the same time, some shortcomings of heat-not-burn products are gradually emerging. Harm reduction does not mean no addictive hazards. Nicotine's addictiveness is still the main source of problems.

[0029] At present, most heat-not-burn smoke-emitting segments use tobacco powder or plant husk powder as fillers, and tobacco extracts are used as the source of the aroma of the heat-not-burn smoke-emitting segments to adjust the flavor of the smoke cartridges. The use of tobacco powder and tobacco extracts to prepare smoke cartridges has a pure taste, but the nicotine content remains unchanged, which will produce a phenomenon of quitting traditional cigarettes but becoming addicted to heat-not-burn products. When tobacco extracts are used as the source of tobacco aroma, nicotine is an unavoidable problem. When plant cores such as green tea and black tea are used as filling materials, the bitter taste of the tea itself remains on the tongue for a longer time, and is very different from the aroma of tobacco itself and fruit.

[0030] Please refer to Figure 1 , Figure 1 A physical picture of an aerosol substrate provided in one embodiment of the present application. This embodiment provides an aerosol substrate, which is applied to a heat-not-burn device, wherein the aerosol substrate comprises a plant base material, a base material solvent, and an adhesive, wherein the plant base material comprises one or more of light bamboo leaf powder, lily powder, licorice powder, Ceylon black tea powder, platycodon powder, gynostemma powder, jasmine powder, hawthorn powder, red date powder, clove powder, rose powder, barley tea powder, and green tea powder.

[0031] The aerosol substrate can be used for the smoking section of a heat-not-burn device. Optionally, the shape of the aerosol substrate is granular. For example, the shape of the aerosol substrate can be cylindrical, circular, rectangular, etc. Optionally, the diameter of the aerosol substrate is 1mm-3mm and the height is 1mm-3mm.

[0032] The aerosol substrate is composed of a plant substrate, a substrate solvent, and an adhesive. The mass ratio of the plant substrate, the substrate solvent, and the adhesive is (60-90):(9-50):(1-2). Optionally, the mass ratio of the plant substrate, the substrate solvent, and the adhesive is 70:15:1, or 75:30:1, or 80:40:2, or 85:45:2, etc.

[0033] The mass ratio of the plant base material, the substrate solvent, and the adhesive is (60-90): (9-50): (1-2), which can not only make the aerosol substrate easy to form, but also make the aerosol substrate have a higher smoke output and a refreshing taste. If the plant base material is too much or too little, the aerosol substrate will be difficult to form. If the substrate solvent is too little, the smoke output of the aerosol substrate will be reduced; if the substrate solvent is too much, the water content of the aerosol substrate will be too high, the mouth will feel sour when inhaled, and the aerosol substrate will be difficult to form. If the adhesive is too little, the aerosol substrate will be difficult to form; if the adhesive is too much, the aerosol substrate will be too hard, affecting its stability.

[0034] Optionally, the base solvent includes one or more of propylene glycol, glycerol, water, and caprylic acid glyceride; and the binder includes sodium carboxymethyl cellulose.

[0035] For example, in the aerosol base material, there are 60-90 parts of plant base material, 1-10 parts of propylene glycol, 5-20 parts of glycerol, 1-10 parts of water, 2-10 parts of caprylic and capric glyceride, and 1-2 parts of sodium carboxymethyl cellulose.

[0036] For example, in the plant base material, the mass percentages of light bamboo leaf powder, lily powder, licorice powder, Ceylon black tea powder, platycodon powder, jasmine powder, and red date powder are 2%:40%:3%:20%:10%:20%:5%.

[0037] For another example, in the plant base material, the mass percentages of lily powder, licorice powder, Ceylon black tea powder, platycodon powder, gynostemma powder, jasmine powder, hawthorn powder, red date powder, clove powder, rose powder, barley tea powder, and green tea powder are 20%: 5%: 5%: 5%: 2%: 10%: 10%: 15%: 10%: 10%: 2%: 6%.

[0038] For another example, in the plant base material, the mass percentages of light bamboo leaf powder, Ceylon black tea powder, platycodon powder, jasmine powder, hawthorn powder, red date powder, clove powder and green tea powder are 10%:40%:5%:5%:5%:3%:2%:30%.

[0039] For another example, in the plant base material, the mass percentage of lily powder is 100%.

[0040] Since a plant base material without tobacco or tobacco product ingredients is used as the base material, and a base solvent and adhesive without tobacco or tobacco product ingredients are used, the aerosol base material does not contain addictive ingredients such as nicotine, thereby obtaining an aerosol base material with no addictive hazards.

[0041] In addition, by using one or more of light bamboo leaf powder, lily powder, liquorice powder, Ceylon black tea powder, platycodon powder, gynostemma powder, jasmine powder, hawthorn powder, red date powder, clove powder, rose powder, barley tea powder, and green tea powder, the aerosol produced by the aerosol substrate can have a unique plant fragrance. When a variety of plant base materials are combined with each other, the various smells are harmonious, the suction feeling is comfortable, the aroma is coordinated, full and delicate, long-lasting, comfortable aftertaste, and less irritating.

[0042] Therefore, this embodiment adopts a specific plant base material as the main material of the aerosol substrate, which not only makes the aerosol substrate non-addictive and reduces damage to the health of users, but also makes the aerosol produced by the aerosol substrate have a unique plant fragrance, thereby improving the smoking effect.

[0043] The aerosol substrate provided in this embodiment does not contain nicotine, so that this nicotine-free product has the ability to replace traditional cigarettes, meets the smoking cessation needs of some smokers, and can satisfy consumers' taste of smoking cigarettes.

[0044] Optionally, a method for preparing a plant base material comprises:

[0045] A foundation material is provided, which includes one or more of light bamboo leaf powder, lily powder, liquorice powder, Ceylon black tea powder, platycodon powder, gynostemma powder, jasmine powder, hawthorn powder, red date powder, clove powder, rose powder, barley tea powder, and green tea powder.

[0046] One or more of the above foundation materials are crushed and sieved through 100-200 mesh.

[0047] The above 100-200 mesh powder foundation material is premixed evenly and placed in a constant temperature and humidity room for 24-32 hours. The constant temperature and humidity room requires a humidity of 35-45RH% and a temperature of 20-25°C, so that the moisture content of the treated powder foundation material is 5±0.5%, thereby obtaining a plant base material.

[0048] In one embodiment, the plant base material consists of a base material and an auxiliary material, and the mass percentage of the base material and the auxiliary material is (60%-100%): (0%-40%).

[0049] Optionally, the base material includes one or more of lily powder, Ceylon black tea powder, and green tea powder, and the auxiliary materials include one or more of light bamboo leaf powder, licorice powder, platycodon powder, gynostemma powder, jasmine powder, hawthorn powder, red date powder, clove powder, rose powder, and barley tea powder.

[0050] The plant base material is composed of a base material and an auxiliary material, wherein the mass percentage of the base material and the auxiliary material can be 70%:30%, or 80%:20%, or 90%:10%. Alternatively, the mass percentage of the base material is 100%, and no auxiliary material is added.

[0051] By setting the base material and the auxiliary material, the base material can be used as the main body of the plant base material, and the auxiliary material can be used as an auxiliary. The auxiliary material can adjust the aroma of the plant base material, that is, adjust the taste of the aerosol base material, and solve the problems of insufficient aftertaste and single fragrance of the aerosol base material.

[0052] For example, when the aftertaste of the aerosol base material is insufficient, the proportion of red date powder in the auxiliary material can be increased. The red date powder can cooperate with one or more of lily powder, Ceylon black tea powder, and green tea powder to enhance the overall aroma of the plant base material.

[0053] For another example, when the aerosol base material has a single fragrance, multiple base materials and multiple auxiliary materials can be added. 80 parts of lily powder and 2 parts of Ceylon black tea powder are used as base materials, and 1 part of licorice powder, 5 parts of jasmine powder, 2 parts of hawthorn powder, 5 parts of clove powder, and 5 parts of rose powder are used as auxiliary materials to improve the fragrance harmony and fragrance persistence of the aerosol generated by the aerosol base material, reduce the miscellaneous smell of the aerosol, reduce the irritation of the aerosol to the nasal cavity, and improve the comfort of the user's inhalation, thereby further improving the inhalation effect. Please refer to Example 1 for details.

[0054] In one embodiment, the aerosol substrate further includes fruit flavor, and the mass ratio of the fruit flavor to the plant base material is (10-20): (60-90).

[0055] Optionally, the mass ratio of the fruit flavor to the plant base material is 13:70, or 15:75, or 18:80, etc.

[0056] The mass ratio of the fruit flavor to the plant base material is (10-20): (60-90), which can not only make the aerosol substrate release a fruity aroma, but also make the aerosol substrate have a refreshing taste. If the plant base material is too much or too little, the aerosol substrate will be difficult to form. If the fruit flavor is too little, the fruity aroma released by the aerosol substrate will be reduced, reducing the suction effect; if the fruit flavor is too much, the aerosol produced by the aerosol substrate will have a strong chemical smell and more miscellaneous flavors, and the aerosol substrate will be difficult to form.

[0057] This embodiment adds fruit flavors to the aerosol base material, so that the aerosol base material can release an aroma and taste close to natural fruit flavor on the basis of a non-addictive aerosol base material, enriching the taste of the aerosol base material and further improving the inhalation effect.

[0058] Optionally, the fruit flavor includes fruit essential oil, a flavoring agent, and a flavor solvent, and the mass ratio of the fruit essential oil, the flavoring agent, and the flavor solvent is (10-20): (28-66): (27-45).

[0059] Further optionally, the mass ratio of the fruit essential oil, the flavoring agent, and the flavor solvent is 13:40:32, or 15:50:38, or 18:60:43, etc.

[0060] The mass fraction ratio of the fruit essential oil, the flavoring agent, and the flavoring solvent is (10-20): (28-66): (27-45), which can make the fruit flavor release an aroma and taste close to natural fruit flavor. If the fruit essential oil and the flavoring agent are too little, the fruity aroma released by the aerosol base material will be reduced, and the suction effect will be reduced; if the fruit essential oil and the flavoring agent are too much, the aerosol produced by the aerosol base material will have a strong chemical smell and more foreign flavors. If the flavoring solvent is too little, the fruit essential oil and the flavoring agent cannot be fully mixed, and the aerosol produced by the aerosol base material will have a strong chemical smell and more foreign flavors; if the flavoring solvent is too much, the aerosol base material will be difficult to form.

[0061] Optionally, the fruit essential oil includes one or more of blueberry essential oil, strawberry essential oil, blackberry essential oil, and cranberry essential oil, the flavoring agent includes one or more of phenylacetaldehyde, alpha-damascenone, lactic acid, honey extract, ethyl vanillin, ethyl acetate, ethyl butyrate, ethyl caproate, methyl caproate, ethyl maltol, γ-undecalactone, leaf aldehyde, cinnamon oil, and chamomile oil, and the flavor solvent includes one or more of water, caprylic capric glyceride, and glycerol.

[0062] Among them, the fruit flavor can be berry flavor.

[0063] Further optionally, in the fruit flavor, blueberry essential oil is 10-20 parts, phenylacetaldehyde is 3-10 parts, methyl-damascenone is 1-2 parts, lactic acid is 2-7 parts, honey extract is 8-15 parts, ethyl vanillin is 1-2 parts, ethyl acetate is 1-3 parts, ethyl butyrate is 2-4 parts, ethyl caproate is 1-3 parts, methyl caproate is 1-3 parts, ethyl maltol is 3-5 parts, γ-undecalactone is 1-2 parts, leaf aldehyde is 1-3 parts, cinnamon oil is 1-2 parts, chamomile oil is 2-5 parts, water is 5-10 parts, caprylic capric glyceride is 2-5 parts, and glycerol is 20-30 parts.

[0064] For example, in fruit flavors, there are 20 parts of blueberry essential oil, 3 parts of phenylacetaldehyde, 1 part of methyl damascenone, 3 parts of lactic acid, 10 parts of honey extract, 1 part of ethyl vanillin, 1 part of ethyl acetate, 2 parts of ethyl butyrate, 2 parts of ethyl caproate, 2 parts of methyl caproate, 3 parts of ethyl maltol, 1 part of γ-undecalactone, 2 parts of leaf aldehyde, 2 parts of cinnamon oil, 3 parts of chamomile oil, 5 parts of water, 5 parts of caprylic capric glyceride, and 20 parts of glycerol.

[0065] For another example, in the fruit flavor, there are 15 parts of blueberry essential oil, 5 parts of phenylacetaldehyde, 2 parts of methyl damascenone, 5 parts of lactic acid, 15 parts of honey extract, 2 parts of ethyl vanillin, 3 parts of ethyl acetate, 4 parts of ethyl butyrate, 3 parts of ethyl caproate, 3 parts of methyl caproate, 5 parts of ethyl maltol, 2 parts of γ-undecalactone, 2 parts of leaf aldehyde, 2 parts of cinnamon oil, 5 parts of chamomile oil, 8 parts of water, 2 parts of caprylic capric glyceride, and 30 parts of glycerol.

[0066] For another example, in fruit flavors, there are 12 parts of blueberry essential oil, 4 parts of phenylacetaldehyde, 1 part of methyl damascenone, 7 parts of lactic acid, 8 parts of honey extract, 1 part of ethyl vanillin, 2 parts of ethyl acetate, 2 parts of ethyl butyrate, 1 part of ethyl caproate, 1 part of methyl caproate, 3 parts of ethyl maltol, 2 parts of γ-undecalactone, 1 part of leaf aldehyde, 1 part of cinnamon oil, 3 parts of chamomile oil, 8 parts of water, 4 parts of caprylic capric glyceride, and 25 parts of glycerol.

[0067] In this embodiment, the flavoring agent is one or more of phenylacetaldehyde, methyl damascone, lactic acid, honey extract, ethyl vanillin, ethyl acetate, ethyl butyrate, ethyl caproate, methyl caproate, ethyl maltol, γ-undecalactone, leaf aldehyde, cinnamon oil, and chamomile oil. These flavoring agents can not only be compounded to produce an aroma close to natural fruit flavor, but also have high heat resistance, so that the fruit flavor has better heat resistance in a heated state (300-350°C), thereby improving the aerosol smoke generated by the aerosol substrate in a heated state (300-350°C) to be clean, long aftertaste, rich fruit flavor, and improve the suction effect.

[0068] It should be emphasized that using one or more of bamboo leaf powder, lily powder, licorice powder, Ceylon black tea powder, platycodon powder, gynostemma powder, jasmine powder, hawthorn powder, red date powder, clove powder, rose powder, barley tea powder, and green tea powder will not produce an aroma that is not conducive to the taste of berries.

[0069] In one embodiment, the fruit flavor also includes a cooling agent, and the mass ratio of the fruit essential oil, the flavoring agent, the flavor solvent, and the cooling agent is (10-20): (28-66): (27-45): (4-9).

[0070] Optionally, the mass ratio of the fruit essential oil, the flavoring agent, the flavor solvent, and the cooling agent is 13:40:32:6, or 15:50:38:7, or 18:60:43:8, etc.

[0071] The mass fraction ratio of the fruit essential oil, the flavoring agent, the flavor solvent, and the cooling agent is (10-20): (28-66): (27-45): (4-9), which can make the fruit flavor release an aroma and taste close to the natural fruit flavor, while having a light mint refreshing taste that is continuously refreshing, and the taste decays slowly from mouth to mouth, thereby improving the pleasure and comfort of the entire smoking process, and meeting the taste needs of smokers who quit smoking. If the cooling agent is too little, the mint refreshing taste released by the aerosol substrate will be reduced, reducing the smoking effect; if the cooling agent is too much, the aerosol produced by the aerosol substrate will cause excessive irritation to the oral cavity and nasal cavity.

[0072] This embodiment adds cooling agents to fruit flavors, so that the fruit flavors can release an aroma and taste close to natural fruit flavors, while having a light minty and refreshing taste that lasts forever. The taste decays slowly from mouthful to mouthful, thereby enhancing the pleasure and comfort of the entire smoking process and meeting the taste needs of smokers who are quitting.

[0073] Optionally, the cooling agent includes one or more of WS-23, menthol, and menthyl lactate.

[0074] Further optionally, in the fruit flavor, blueberry essential oil is 10-20 parts, phenylacetaldehyde is 3-10 parts, methyl-damascenone is 1-2 parts, lactic acid is 2-7 parts, honey extract is 8-15 parts, ethyl vanillin is 1-2 parts, ethyl acetate is 1-3 parts, ethyl butyrate is 2-4 parts, ethyl caproate is 1-3 parts, methyl caproate is 1-3 parts, ethyl maltol is 3-5 parts, γ-undecalactone is 1-2 parts, leaf aldehyde is 1-3 parts, cinnamon oil is 1-2 parts, WS-23 is 2-5 parts, menthol is 1-2 parts, menthyl lactate is 1-2 parts, chamomile oil is 2-5 parts, water is 5-10 parts, caprylic capric glyceride is 2-5 parts, and glycerol is 20-30 parts.

[0075] For example, in fruit flavors, there are 20 parts of blueberry essential oil, 3 parts of phenylacetaldehyde, 1 part of methyl damascone, 3 parts of lactic acid, 10 parts of honey extract, 1 part of ethyl vanillin, 1 part of ethyl acetate, 2 parts of ethyl butyrate, 2 parts of ethyl caproate, 2 parts of methyl caproate, 3 parts of ethyl maltol, 1 part of γ-undecalactone, 2 parts of leaf aldehyde, 2 parts of cinnamon oil, 5 parts of WS-23, 1 part of menthol, 1 part of menthyl lactate, 3 parts of chamomile oil, 5 parts of water, 5 parts of caprylic capric glyceride, and 20 parts of glycerol.

[0076] For another example, in the fruit flavor, there are 15 parts of blueberry essential oil, 5 parts of phenylacetaldehyde, 2 parts of methyl damascenone, 5 parts of lactic acid, 15 parts of honey extract, 2 parts of ethyl vanillin, 3 parts of ethyl acetate, 4 parts of ethyl butyrate, 3 parts of ethyl caproate, 3 parts of methyl caproate, 5 parts of ethyl maltol, 2 parts of γ-undecalactone, 2 parts of leaf aldehyde, 2 parts of cinnamon oil, 2 parts of WS-23, 2 parts of menthol, 2 parts of menthyl lactate, 5 parts of chamomile oil, 8 parts of water, 2 parts of caprylic capric glyceride, and 30 parts of glycerol.

[0078] The fruit flavor provided in this embodiment uses various types of berry powder and pure oil, and is assisted by the addition of various flavors and fragrances adapted to the heating-without-burning heating characteristics, so it can restore the berry aroma and produce a pleasant berry flavor.

[0079] In one embodiment, the aerosol substrate further comprises fruit powder, and the mass ratio of the fruit powder to the plant base material is (5-10):(60-90).

[0080] Optionally, the mass ratio of the fruit powder to the plant base material is 6:70, or 7:75, or 8:80, etc.

[0081] The mass ratio of the fruit powder to the plant base is (5-10): (60-90), which can make the aerosol base release an aroma and taste close to natural fruit flavor. If the fruit powder is too little, the fruity aroma released by the aerosol base will be reduced, reducing the suction effect; if the fruit powder is too much, the aerosol produced by the aerosol base will have a single taste, covering up the fragrance of the plant base.

[0082] This embodiment can modify the taste of smoke by adding fruit powder to the aerosol base material, harmonize the smoke and produce a strong berry flavor to enrich the taste.

[0083] Optionally, the fruit powder includes one or more of strawberry fruit powder, blueberry fruit powder, blackberry fruit powder, and cranberry powder.

[0084] The fruit powder may be berry powder.

[0087] For another example, the mass percentage of blueberry powder is 100%.

[0088] Optionally, a method for preparing fruit powder comprises:

[0089] Natural strawberries, blueberries, blackberries and cranberries are freeze-dried using freeze-drying technology, which ensures that some heat-sensitive substances in the berries will not be deformed or inactivated, and some flavor substances will not be lost.

[0090] After freeze-drying, the product is crushed and sieved through 100-200 mesh.

[0091] The above 100-200 mesh berry powder is premixed evenly and placed in a constant temperature and humidity room for 24-32 hours.
