When used, the aerosol generating substrate segment is heated to release the aerosol.

[0032] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0033] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The descriptions of "first", "second", etc. in the embodiments of the present application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0034] On the one hand, the present application provides an aerosol generating product. Figures 1 to 3 The aerosol generating article 100 comprises an aerosol generating substrate segment 1 and a wrapping layer 2. The aerosol generating substrate segment 1 is used to generate aerosol. The wrapping layer 2 comprises an impermeable layer 21 and a connecting layer 22. The outer peripheral surface of the aerosol generating substrate segment 1 is wrapped with the impermeable layer 21, and the connecting layer 22 is wrapped on the outer peripheral surface of the impermeable layer 21.

[0035] The aerosol generating product 100 provided in the embodiment of the present application, on the one hand, by wrapping the anti-seepage layer 21 on the outer peripheral surface of the aerosol generating matrix segment 1, not only can the aerosol generating matrix segment 1 be protected to a certain extent, but also can prevent the substances in the smoke-generating medium in the aerosol generating matrix segment 1 from leaking to the surface of the aerosol generating product 100, so as to ensure the neat appearance and the mouth feel of the aerosol generating product 100. On the other hand, by arranging the connecting layer 22 on the outer peripheral surface of the anti-seepage layer 21, the aerosol generating matrix segment 1 can be further protected to a certain extent, and the surface area of ​​the aerosol generating matrix segment 1 directly exposed to the outside world can be reduced, thereby reducing the probability of the aerosol generating matrix segment 1 being damp and deteriorated due to contact with the air, and at the same time, reducing the probability of the aerosol generating matrix segment 1 being contaminated by contact with other components in the aerosol generating device.

[0036] It should be noted that the substance in the smoke-generating medium described here can be a liquid substance such as glycerin and propylene glycol that easily absorbs moisture in the air.

[0037] It should be noted that the anti-seepage layer 21 mentioned here is capable of blocking substances in the smoke-generating medium to prevent the substances from passing through the anti-seepage layer 21 and entering the connecting layer 22 .

[0038] In one embodiment, please refer to Figures 1 to 3 The aerosol-generating article 100 includes a support segment 3, which is disposed at one end of the aerosol-generating substrate segment 1 in the longitudinal direction. Exemplarily, the support segment 3 can withstand the temperature of the aerosol from the aerosol-generating substrate segment 1 and maintain the shape. In this way, by contacting one end of the support segment 3 with the aerosol-generating substrate segment 1, the aerosol-generating substrate segment 1 can be supported and positioned to prevent the aerosol-generating substrate segment 1 from moving in the longitudinal direction.

[0039] The outer circumference of the support segment 3 is wrapped with an impermeable layer 21. Thus, by wrapping the outer circumference of the support segment 3 with the impermeable layer 21, the aerosol generated by the aerosol generating substrate segment 1 during the heating process can be prevented from condensing and penetrating into the outer surface of the aerosol generating product 100 after the support segment 3 is cooled, thereby ensuring that the appearance of the aerosol generating product 100 is neat.

[0040] Exemplarily, in one embodiment, the anti-seepage layer 21 may be one layer or multiple layers. Figure 1 , Figure 2 and Figure 3 The anti-seepage layer 21 is a single layer, which is wrapped around the outer peripheral surface of the aerosol generating matrix segment 1 and the outer peripheral surface of the supporting segment 3, and then the connecting layer 22 is wrapped around the outer peripheral surface; it may also include two layers, one anti-seepage layer 21 is wrapped around the outer peripheral surface of the aerosol generating matrix segment 1, the other anti-seepage layer 21 is wrapped around the outer peripheral surface of the supporting segment 3, and then a connecting layer 22 is wrapped around the outer peripheral surface of the two anti-seepage layers 21.

[0041] In some embodiments, the support segment 3 can withstand a temperature not higher than the first temperature, that is, the support segment 3 still maintains its shape at the first temperature. In this way, the support segment 3 has the characteristics of high heat resistance, which can avoid the risks of thermal collapse, thermal deformation, and residues that may fall from the support segment 3 blocking the airway of the aerosol generating matrix segment 1, causing unstable aerosol release, etc.

[0042] It should be noted that micropores may exist inside the aerosol generating matrix segment 1. For example, for the aerosol generating matrix segment 1 of the particle combination, the gaps between the particles constitute micropores. However, the airway described in the present application is different from the micropores. The airway described in the present application belongs to the pores in the macroscopic sense, and the micropores belong to the pores in the microscopic sense. The projected area and length of the airway are much larger than those of the micropores. The airway is mainly formed by design and processing, such as by die processing. Therefore, the projected area and length of the airway can be changed according to the design requirements, while the size of the micropore is determined by the gaps between the particles. For example, the material is a granular material, and the aerosol generating matrix segment 12 formed by extrusion of the material has micropores. The projected area and length of the micropores are naturally formed by the extrusion process and the material components. The material feeding tube expands to a certain extent after flowing out of the die, which can form micropores.

[0043] In one embodiment, the material of the connecting layer 22 is fiber paper or PE (polyethylene). Exemplarily, the material of the connecting layer 22 can be fiber paper. On the one hand, fiber paper has high strength, which can effectively protect the aerosol generating matrix segment 1 from external damage and maintain the integrity and shape of the aerosol generating product 100; on the other hand, fiber paper has a certain air permeability, so that the suction taste can be improved to a certain extent; on the other hand, the production cost of fiber paper is low, which can reduce the production cost of the aerosol generating product 100. The material of the connecting layer 22 can also be PE. On the one hand, PE has good waterproof and moisture-proof properties, which can keep the aerosol generating product dry and prevent the taste and quality from being affected by moisture; on the other hand, PE has good wear resistance, which can resist external wear and keep the appearance of the aerosol generating product 100 intact.

[0044] Exemplarily, in one embodiment, a flavored additive may be added to the connecting layer 22 to give the user a better smoking experience.

[0045] Exemplarily, in one embodiment, a mark or the like may be printed on the connection layer 22 to provide the user with direction identification and provide a good user experience.

[0046] In one embodiment, please refer to Figure 1 The aerosol generating article 100 comprises a cleaning section 4 , which is arranged at one end of the aerosol generating substrate section 1 away from the supporting section 3 in the longitudinal direction. On the one hand, the external airflow can be reduced or blocked from contacting the aerosol generating matrix segment 1 through the end face of the aerosol generating matrix segment 1 that is away from the supporting segment 3 in the longitudinal direction, thereby reducing the heat dilution caused by the external airflow, so that the temperature field of the heated aerosol generating matrix segment 1 is relatively stable and the thermal efficiency is good; on the other hand, one end of the aerosol generating matrix segment 1 in the longitudinal direction is blocked, so that the aerosol generating matrix segment 1 is heated to generate aerosol in a low-oxygen or oxygen-free environment. At this time, the generated aerosol will diffuse toward the aerobic area, that is, diffuse toward the external airflow, and finally be extracted by the external airflow. Since the aerosol generating matrix segment 1 has less oxygen involved in the heating process, the generation of harmful substances can be reduced, and the probability of carbonization of the aerosol generating matrix segment 1 can be reduced; on the other hand, by setting a cleaning segment 4 on the end face of the aerosol generating matrix segment 1 that is away from the supporting segment 3 in the longitudinal direction, the suction resistance of the aerosol generating product 100 can be adjusted to effectively solve the problem of the aerosol generating matrix segment 1 falling off after inhalation.

[0047] The outer circumference of the cleaning section 4 is wrapped with an impermeable layer 21. Thus, by wrapping the outer circumference of the cleaning section 4 with the impermeable layer 21, on the one hand, the aerosol generated by the aerosol generating substrate section 1 during the heating process can be prevented from condensing on the inner wall of the cleaning section 4 and penetrating to the outer surface of the aerosol generating article 100; on the other hand, it can also prevent the substances in the smoke-generating medium in the support section 3 and the aerosol generating substrate section 1 from flowing longitudinally into the cleaning section 4 under the action of gravity to cause external infiltration.

[0048] In one embodiment, please refer to Figures 1 to 3 The aerosol generating product 100 includes a cooling section 5, which is arranged at one end of the support section 3 that is away from the aerosol generating matrix section 1 in the longitudinal direction. In this way, the aerosol generated by the aerosol generating matrix section 1 flows through the support section 3 and the cooling section 5 in sequence under the action of the suction negative pressure. In this way, by arranging the cooling section 5 at one end of the support section 3 that is away from the aerosol generating matrix section 1 in the longitudinal direction, the inlet temperature of the aerosol can be reduced to a level that the human body can accept, so as to solve the problem of "burning the mouth" during the suction process. In addition, according to the principle of heat exchange, when the aerosol passes through the support section 3, the support section 3 can also have a certain cooling effect on the aerosol.

[0049] The outer peripheral surface of the cooling section 5 is wrapped with a connecting layer 22. In this way, on the one hand, the cooling section 5 can be protected to a certain extent and the service life of the cooling section 5 can be improved; on the other hand, the cooling section 5, the support section 3, the aerosol generating matrix section 1 and the cleaning section 4 can be connected by the connecting layer 22 to improve the connection stability.

[0050] In one embodiment, please refer to Figures 1 to 3 The aerosol generating article 100 includes a filter section 6, which is disposed at one end of the cooling section 5 away from the support section 3 in the longitudinal direction. Exemplarily, the filter section 6 can not only block substances of target particle size, but also adjust the inhalation resistance. For example, the filter section 6 can filter large-size particles similar to powdery substances. The aerosol filtered by the filter section 6 has a higher consistency in particle size and a more delicate taste.

[0051] The outer peripheral surface of the filter section 6 is wrapped with a connecting layer 22. In this way, on the one hand, the filter section 6 can be protected to a certain extent and the service life of the filter section 6 can be improved; on the other hand, the filter section 6, the cooling section 5, the support section 3, the aerosol generating matrix section 1 and the cleaning section 4 can be connected through the connecting layer 22 to improve the connection stability.

[0052] Illustratively, in one embodiment, the outer peripheral surfaces of the filter section 6 and the cooling section 5 can be wrapped with an impermeable layer 21, and then the connecting layer 22 is wrapped on the outer peripheral surface of the impermeable layer 21. In this way, the aerosol can be prevented from condensing in the filter section 6 and the cooling section 5 and penetrating into the outer peripheral surface of the aerosol generating product 100.

[0053] Exemplarily, in one embodiment, the anti-seepage layer 21 may not be provided on the outer peripheral surface of the filtration section 6 and the cooling section 5, because both the filtration section 6 and the cooling section 5 contain adsorbents, which can adsorb the liquid after the aerosol is condensed. In this way, the cost of the aerosol generating product 100 can be reduced.

[0054] In one embodiment, the aerosol generating article 100 includes at least one of the cooling section 5 and the filtering section 6, and at least one of the cooling section 5 and the filtering section 6 is arranged at one end of the aerosol generating substrate section 1 in the longitudinal direction. Exemplarily, the aerosol generating article 100 includes the cooling section 5, and the cooling section 5 can be arranged at one end of the aerosol generating substrate section 1 in the longitudinal direction; the aerosol generating article 100 includes the cooling section 5 and the supporting section 3, and the supporting section 3 is arranged at one end of the aerosol generating substrate section 1 in the longitudinal direction, and the cooling section 5 is arranged at one end of the supporting section 3 in the longitudinal direction away from the aerosol generating substrate section 1 in the longitudinal direction. The aerosol generating product 100 includes a cooling section 5 and a filtering section 6. The cooling section 5 can be arranged at one end of the aerosol generating matrix section 1 along the longitudinal direction, and the filtering section 6 is arranged at one end of the cooling section 5 along the longitudinal direction away from the aerosol generating matrix section 1; the aerosol generating product 100 includes a cooling section 5, a filtering section 6 and a supporting section 3. The supporting section 3 is arranged at one end of the aerosol generating matrix section 1 along the longitudinal direction, the cooling section 5 is arranged at one end of the supporting section 3 along the longitudinal direction away from the aerosol generating matrix section 1 along the longitudinal direction, and the filtering section 6 is arranged at one end of the cooling section 5 along the longitudinal direction away from the aerosol generating matrix section 1.

[0055] See also Figure 1 and Figure 2 , the wrapping layer 2 includes an anti-leakage layer 23, and the outer peripheral surface of the filter section 6 and / or the cooling section 5 is wrapped with the anti-leakage layer 23. Exemplarily, the outer peripheral surface of the filter section 6 may be wrapped with the anti-leakage layer 23, the outer peripheral surface of the cooling section 5 may be wrapped with the anti-leakage layer 23, or the outer peripheral surfaces of the filter section 6 and the cooling section 5 may be wrapped with the anti-leakage layer 23. In this way, by providing the anti-leakage layer 23, on the one hand, the rising aerosol can be prevented from flowing out from the outside of the filter section 6 and / or the cooling section 5, thereby improving the utilization rate of the aerosol; on the other hand, the strength of the filter section 6 and / or the cooling section 5 along the longitudinal direction can be increased, making it difficult to bend, thereby increasing the stiffness of the aerosol generating product 100.

[0056] The connection layer 22 is wrapped around the outer peripheral surface of the anti-leakage layer 23. In this way, on the one hand, the cooling section 5 and / or the filtering section 6 can be protected to a certain extent, and the service life of the cooling section 5 and / or the filtering section 6 can be improved; on the other hand, the cooling section 5 and / or the filtering section 6 can be connected with the support section 3 and the aerosol generating matrix section 1 through the connection layer 22, and the connection stability can be improved.

[0057] In some embodiments, with the plane perpendicular to the longitudinal direction as the projection plane, the projection of the filter segment 6, the projection of the support segment 3, the projection of the cleaning segment 4, the projection of the cooling segment 5 and the projection of the aerosol generating matrix segment 1 all overlap. Exemplarily, in one embodiment, the projection of the filter segment 6, the projection of the support segment 3, the projection of the cleaning segment 4, the projection of the cooling segment 5 and the projection of the aerosol generating matrix segment 1 are all circular and have the same outer diameter. This facilitates the assembly of the above structure into the connecting layer 22.

[0058] In order to prevent the internal substances of the aerosol generating matrix segment, such as substances in the smoke medium, from penetrating to the outer surface, some related technologies use metal or plastic film as anti-seepage paper on the outer surface of the aerosol generating product. Although this can achieve a certain anti-seepage effect, the introduction of metal or plastic cannot guarantee the biological safety of the anti-seepage paper during actual use. In other related technologies, the anti-seepage effect is achieved by using metal as the inner layer and oil-proof and hydrophobic coating as the outer layer of the anti-seepage paper. However, the oil-proof and hydrophobic coating may contain some toxic substances and cannot ensure biological safety.

[0059] In one embodiment, the impermeable layer 21 includes at least one of a coated paper and a laminated paper. Exemplarily, the impermeable layer 21 may be a coated paper. On the one hand, the coated paper has excellent water and oil resistance, and can effectively prevent the substances in the smoke medium and the liquid after the aerosol condensation from penetrating into the outer peripheral surface of the aerosol generating product 100, so that the appearance of the aerosol generating product 100 can be kept neat; on the other hand, the coated paper has good biosafety and can reduce the harm to the human body. The impermeable layer 21 may also be a laminated paper. On the one hand, the laminated paper has excellent water and oil resistance, and can effectively prevent the substances in the smoke medium and the liquid after the aerosol condensation from penetrating into the outer peripheral surface of the aerosol generating product 100, so that the appearance of the aerosol generating product 100 can be kept neat; on the other hand, the laminated paper can improve the hardness and stability of the aerosol generating product 100, making the aerosol generating product 100 easy to carry. The impermeable layer 21 may also be a composite paper composed of laminated paper and coated paper, so that the impermeability effect of the impermeable layer 21 can be further improved.

[0060] The working temperature of the impermeable layer 21 is not higher than 350° C. (including 350° C.). Exemplarily, the working temperature of the impermeable layer 21 can be between 250° C. and 350° C. In this way, by setting a suitable working temperature, while ensuring that the aerosol generating substrate segment 1 can be fully heated to generate aerosol, the impermeable layer 21 will not be damaged, such as cracking.

[0061] It should be noted that coated paper refers to special paper impregnated with resin material and dried to a certain degree of fixation. Laminated paper refers to a composite material in which plastic particles are coated on the surface of special paper.

[0062] Exemplarily, in one embodiment, the anti-seepage layer 21 may be made of hemp pulp fiber paper as the bottom layer, and then the hemp pulp fiber paper is coated with polysaccharide or PLA (polylactic acid).

[0063] In one embodiment, the weight of the anti-seepage layer 21 is 20 g / m 2 Up to 75g / m 2 For example, the weight of the anti-seepage layer 21 may be 20 g / m 2 , 25g / m 2 , 30g / m 2 , 35g / m 2 , 40g / m 2 , 45g / m 2 , 50g / m 2 , 55g / m 2 , 60g / m 2 , 65g / m 2 , 70g / m 2 or 75g / m 2 By setting a suitable gram weight value, not only can the load capacity of the anti-seepage layer 21 be increased, thereby increasing the anti-seepage effect, but also the overall weight of the aerosol generating product 100 can be reduced, making it easier to carry.

[0064] For example, in one embodiment, the weight of the anti-seepage layer 21 is 40 g / m 2 Up to 65g / m 2 between.

[0065] In one embodiment, the air permeability of the barrier layer 21 is between 20cu and 60cu. For example, the air permeability of the barrier layer 21 can be 20cu, 25cu, 30cu, 35cu, 40cu, 45cu, 50cu, 55cu or 60cu, etc. Thus, by setting a suitable air permeability, the aspiration resistance, aerosol temperature, and aerosol aggregation of the aerosol generating article 100 can be adjusted.

[0066] It can be understood that the air permeability is an indicator used to describe the air permeability of paper. For example, an air permeability of 20cu means that the maximum air permeability allowed per square inch of paper is 20 cubic inches.

[0067] In one embodiment, the anti-leakage layer 23 is made of air-permeable fiber paper. On the one hand, the air-permeable fiber paper has high air permeability, and can effectively adjust the air humidity while preventing the infiltration of aerosols and foreign matter; on the other hand, the air-permeable fiber paper has high strength, which can enhance the longitudinal strength of the cooling section 5 and the filtering section 6, and improve the stiffness of the aerosol generating article 100.

[0068] In one embodiment, the air-permeable fiber paper is broadleaf pulp fiber paper. On the one hand, broadleaf pulp fiber has a wide range of sources, abundant resources, and low cost; on the other hand, broadleaf pulp fiber contains more impurities, which makes the paper made of broadleaf pulp fiber have certain durability and stability, and improves the strength of the aerosol generating product 100.

[0069] Exemplarily, in one embodiment, the breathable fiber paper may also be hemp pulp fiber paper, coniferous pulp fiber paper or bamboo pulp fiber paper.

[0070] In one embodiment, the air permeability of the anti-leakage layer 23 is not greater than 20cu. Exemplarily, the air permeability of the anti-leakage layer 23 can be 0cu, 3cu, 6cu, 9cu, 12cu, 15cu, 18cu or 20cu, etc. In this way, by setting the anti-leakage layer 23 with an air permeability of not more than 20cu, it is shown that the anti-leakage layer 23 has good anti-air permeability, which can effectively prevent the aerosol and the liquid after the aerosol condensation from seeping out, and improve the utilization rate of the aerosol.

[0071] In one embodiment, the weight of the anti-leakage layer 23 is 20 g / m 2 Up to 65g / m 2 For example, the weight of the anti-leakage layer 23 may be 20 g / m 2 , 25g / m 2 , 30g / m 2 , 35g / m 2 , 40g / m 2 , 45g / m 2 , 50g / m 2 , 55g / m 2 , 60g / m 2 or 25g / m 2 Etc., in this way, by setting a suitable gram weight value, not only can the load capacity of the anti-leakage layer 23 be increased, thereby increasing the anti-air permeability effect, but also the overall weight of the aerosol generating product 100 can be reduced, making it easier to carry.

[0072] Exemplarily, in one embodiment, the anti-seepage layer 21 and the anti-leakage layer 23 may not overlap in the transverse direction, so that the anti-leakage layer 23 can be first wrapped on the outer peripheral surface of the cooling section 5 and the filtration section 6, and then the anti-seepage layer 21 can be wrapped on the supporting section 3, the aerosol generating matrix section 1 and the cleaning section 4, and finally the connecting layer 22 can be wrapped on the outer peripheral surface of the anti-seepage layer 21 and the anti-leakage layer 23 to connect them into a whole; the anti-seepage layer 21 and the anti-leakage layer 23 do not overlap in the transverse direction, which can not only reduce the use of the anti-seepage layer 21 and / or the anti-leakage layer 23 and reduce costs, but also avoid the increase of impurities in the suction process caused by the overlap of the anti-seepage layer 21 and the anti-leakage layer 23.

[0073] It should be noted that the longitudinal direction refers to the extension direction of the aerosol generating substrate segment 1. For example, the aerosol generating substrate segment 1 is formed by extrusion, and the longitudinal direction is the extrusion direction of the aerosol generating substrate segment 1. The transverse direction intersects the longitudinal direction. Exemplarily, the transverse direction may be perpendicular to the longitudinal direction or the transverse direction may be inclined relative to the longitudinal direction (i.e., the angle between the transverse direction and the longitudinal direction is not equal to 90°).

[0074] Illustratively, in one embodiment, the structure of the aerosol generating substrate segment 1 can be integrally formed, for example, formed into multiple holes by extrusion molding, or can be in the form of a thin sheet or a filament.

[0075] On the other hand, an embodiment of the present application provides an aerosol generating device, which is used for the aerosol generating product 100 in any one of the above embodiments. The aerosol generating device includes a heating component, and the heating component is used to heat the aerosol generating substrate segment 1 to generate an aerosol.

[0076] The heating methods of the heating component include, but are not limited to, resistance heating, electromagnetic heating, infrared heating, microwave heating or laser heating. Transferring heat in the form of thermal convection means that the heating component is not in contact with the aerosol generating matrix segment 1, and the heating component first heats the air, and then the hot air bakes and heats the aerosol generating matrix segment 1. Thermal conduction means that the heating component is in contact with the aerosol generating matrix segment 1 and conducts heat to the aerosol generating matrix segment 1. Exemplarily, resistance and electromagnetic heating mainly transfer heat to the aerosol generating matrix segment 1 in the form of thermal conduction or thermal convection. Infrared heating, microwave heating or laser heating mainly transfer heat to the aerosol generating matrix segment 1 in the form of thermal radiation. That is, the heating component can heat the aerosol generating matrix segment 1 in one or more of the three forms of thermal conduction, thermal convection and thermal radiation.

[0077] In one embodiment, the aerosol-generating substrate segment 1 includes plant raw materials, auxiliary raw materials, smoke-generating agent raw materials, adhesive raw materials and flavor raw materials.

[0078] The plant raw material is used to generate aerosol when heated. The auxiliary raw material is used to provide a skeleton support for the plant raw material. The smoke-generating agent raw material is used to generate a large amount of smoke when heated. The adhesive raw material is used to bond the component raw materials. The flavor raw material is used to provide a characteristic aroma. In this way, the plant raw material and the smoke-generating agent raw material can ensure the amount of aerosol generated, while the flavor raw material can enhance the release of aroma during the suction process and enhance the user experience. The auxiliary raw material can not only improve the fluidity of the mixed material, but also make the aerosol generating matrix segment 1 porous, so as to facilitate the extraction and flow of the aerosol. The adhesive raw material ensures that the plant raw material powder and the auxiliary agent constitute a stable mixture to avoid a loose structure.

[0079] In one embodiment, the plant raw material is one or more combinations of powders formed by crushing tobacco raw materials, tobacco leaf fragments, tobacco stems, tobacco dust, and aromatic plants. The plant raw material is the core source of flavor. The endogenous substances in the plant raw material can produce physiological satisfaction for the user. The endogenous substances, such as alkaloids, enter the human blood and promote the pituitary gland to produce dopamine, thereby obtaining physiological satisfaction.

[0080] In one embodiment, the auxiliary agent raw material can be one or more combinations of inorganic fillers, lubricants, and emulsifiers. Among them, the inorganic filler includes one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. The inorganic filler can provide a skeleton support for the plant raw material, and the inorganic filler also has micropores, which can increase the porosity of the aerosol generation matrix segment 1, thereby increasing the aerosol release rate.

[0081] The lubricant includes one or more combinations of candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. The lubricant can increase the fluidity of the plant raw material powder, reduce the friction between the plant raw material powders, make the overall density of the plant raw material powder distribution more uniform, and also reduce the pressure required in the extrusion molding process and reduce the wear of the die.

[0082] The emulsifier includes one or more combinations of polyglycerol fatty acid ester, Tween-80, and polyvinyl alcohol. The emulsifier can slow down the loss of flavor substances during storage to a certain extent, increase the stability of flavor substances, and improve the sensory quality of the product.

[0083] In one embodiment, the smoke-generating agent raw material may include: a monohydric alcohol (such as menthol); a polyhydric alcohol (such as propylene glycol, glycerol, triethylene glycol, 1,3-butylene glycol and tetraethylene glycol); an ester of a polyhydric alcohol (such as triacetin, triethyl citrate, a mixture of diacetin esters, triethyl citrate, benzyl benzoate, glyceryl tributyrate); a monocarboxylic acid; a dicarboxylic acid; a polycarboxylic acid (such as lauric acid, myristic acid) or an aliphatic ester of a polycarboxylic acid (such as dimethyl dodecanedioate, dimethyl tetradecanedioate, erythritol, 1,3-butylene glycol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, Triactin, meso-erythritol, a mixture of diacetin esters, diethyl suberate, triethyl citrate, benzyl benzoate, benzyl phenylacetate, ethyl vanillate, glyceryl tributyrate, lauryl acetate) or one or more combinations thereof.

[0084] In one embodiment, the adhesive raw material is in close contact with the component raw material interface by wetting, generating intermolecular attraction, thereby playing the role of bonding the component raw materials such as powders, liquids, etc. The adhesive raw material can be a natural plant extract, a non-ionized modified viscous polysaccharide, including one or more combinations of tamarind polysaccharide, guar gum, and modified cellulose (such as carboxymethyl cellulose). The adhesive is used to bond the particles together, which is not easy to loosen. In addition, it improves the water resistance of the aerosol generating matrix 1 and is harmless to the human body.

[0085] In one embodiment, the flavor raw material is used to provide a characteristic aroma, such as a solid or liquid substance of hay aroma, roasted sweet aroma, and nicotine. The flavor raw material may include one or more combinations of tobacco, flavor plant extracts, extracts, essential oils, and absolute oils; the flavor raw material may include one or more combinations of monomer flavor substances, such as megastigmatriene, neophytadiene, geraniol, nerol, and the like.

The wrapping layer 2 includes an impermeable layer 21, a connecting layer 22 and an anti-leakage layer 23. The impermeable layer 21 is wrapped around the outer circumference of the aerosol generating matrix section 1, the supporting section 3 and the cleaning section 4. The anti-leakage layer 23 is wrapped around the outer circumference of the cooling section 5 and the filtering section 6. The impermeable layer 21 is made of 60g / m 2 The hemp pulp fiber paper is coated with polysaccharide on the inside of the hemp pulp fiber paper, and its air permeability is between 30cu and 60cu. The anti-leakage layer 23 is 25g / m 2 The broadleaf pulp fiber forming paper has an air permeability of no more than 20cu. The outer peripheral surface of the anti-leakage layer 23 and the anti-seepage layer 21 is attached with a connecting layer 22, whose gram weight is 40g / m 2 . The anti-seepage layer 21 can prevent the aerosol generated by the aerosol generating matrix segment 1 during the heating process from condensing and condensing in the aerosol generating matrix segment 1, the supporting segment 3 and the cleaning segment 4 to form external oozing and causing yellow spots, thereby ensuring that the appearance of the aerosol generating product 100 is neat. The anti-leakage layer 23 can prevent the aerosol from flowing out from the outside of the cooling segment 5 and the filtering segment 6, thereby improving the utilization rate of the aerosol. The connecting layer 22 can connect the aerosol generating matrix segment 1 and one section of the supporting segment 3 wrapped with the anti-seepage layer 21 and the other section of the anti-leakage layer 23 wrapped with the cooling segment 5 and the filtering segment 6; flavored additives can also be added to the connecting layer 22 to give the user a better smoking taste; secondly, marks can be printed on the outer peripheral surface of the connecting layer 22 to provide the user with direction identification.

[0088] In the second example, see Figure 2The aerosol generating product 100 includes an aerosol generating matrix section 1, a supporting section 3, a cooling section 5, a filtering section 6 and a wrapping layer 2. The wrapping layer 2 includes an impermeable layer 21, a connecting layer 22 and an anti-leakage layer 23. The impermeable layer 21 is wrapped around the outer peripheral surfaces of the aerosol generating matrix section 1 and the supporting section 3. The anti-leakage layer 23 is wrapped around the outer peripheral surfaces of the cooling section 5 and the filtering section 6. The impermeable layer 21 is made of 50g / m 2 The hemp fiber paper is coated with PLA on the inside of the hemp fiber paper. The air permeability of the anti-seepage layer 21 is between 40cu and 60cu. The anti-leakage layer 23 is 25g / m 2 The broadleaf pulp fiber forming paper has an air permeability of no more than 20cu. The outer peripheral surfaces of the anti-leakage layer 23 and the anti-seepage layer 21 are attached with a connecting layer 22, and the gram weight of the connecting layer 22 is 50g / m 2 . The anti-seepage layer 21 can prevent the aerosol generated by the aerosol generating matrix segment 1 during the heating process from condensing and condensing in the aerosol generating matrix segment 1 and the supporting segment 3 to form external oozing and causing yellow spots, thereby ensuring that the appearance of the aerosol generating product 100 is neat. The anti-leakage layer 23 can prevent the aerosol from flowing out from the outside of the cooling segment 5 and the filtering segment 6, thereby improving the utilization rate of the aerosol. The connecting layer 22 can connect one section of the aerosol generating matrix segment 1 and the supporting segment 3 wrapped with the anti-seepage layer 21 and another section of the anti-leakage layer 23 wrapped with the cooling segment 5 and the filtering segment 6; flavored additives can also be added to the connecting layer 22 to give users a better smoking taste; secondly, marks can be printed on the outer peripheral surface of the connecting layer 22 to provide users with direction identification.

[0089] In the third embodiment, please refer to Figure 3 The aerosol generating article 100 includes an aerosol generating matrix section 1, a supporting section 3, a cooling section 5, a filtering section 6 and a wrapping layer 2. The wrapping layer 2 includes an impermeable layer 21 and a connecting layer 22. The impermeable layer 21 is wrapped around the outer peripheral surface of the aerosol generating matrix section 1 and the supporting section 3. The impermeable layer 21 is made of 55g / m 2 The hemp pulp fiber paper is coated with PLA inside the hemp pulp fiber paper. The air permeability of the anti-seepage layer 21 is between 20cu and 30cu. The anti-seepage layer 21, the cooling section 5 and the filtering section 6 are attached with a connecting layer 22. The gram weight of the connecting layer 22 is 50g / m 2. This method can prevent the aerosol generated by the aerosol generating matrix segment 1 during the heating process from condensing and condensing in the aerosol generating matrix segment 1 and the supporting segment 3 to form external oozing and yellow spots, thereby ensuring that the appearance of the aerosol generating product 100 is neat. The connecting layer 22 can connect the aerosol generating matrix segment 1 and one section of the supporting segment 3 wrapped with the anti-seepage layer 21 and another section of the anti-leakage layer 23 wrapped with the cooling segment 5 and the filtering segment 6; flavored additives can also be added to the connecting layer 22 to give users a better smoking taste; secondly, marks can be printed on the outer peripheral surface of the connecting layer 22 to provide users with direction identification.

[0090] The main difference between the second embodiment and the third embodiment is that the third embodiment eliminates the anti-leakage layer 23. When using a high atomizer addition, such as an aerosol generation matrix segment 1 with a porous structure, it is necessary to add an anti-leakage layer 23 to prevent the aerosol from flowing out from the outside of the cooling segment 5 and the filtering segment 6. When using an aerosol generation matrix segment 1 with less atomizer addition, such as NSC and infrared, it is not necessary to use the anti-leakage layer 23 to reduce the processing steps and reduce the cost.

[0091] First Embodiment The structure of the aerosol generating substrate segment 1 in the second embodiment is integrally formed, for example, by extrusion forming to form multiple pores, with low suction resistance, fast flow rate and high aerosol agent loading. The structure of the aerosol generating substrate segment 1 in the third embodiment is thin sheet or filament.

[0092] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. All modifications, equivalent substitutions, improvements, etc. within the spirit and principles of the present application are included in the protection scope of the present application.
