[0002] Aerosol generating products generally generate aerosols by heating without burning. Specifically, the aerosol generating substrate of the aerosol generating product is heated by an external heat source so that it is heated just enough to emit a fragrance. The aerosol generating product does not burn and is usually loaded with an atomizer.

[0064] 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.

[0065] In the description of this application, the "first direction" orientation or position relationship is based on the attached Figures 1 to 4 , Fig.29 and Fig.30 Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0066] The present application embodiment provides an aerosol generating product, please refer to Figures 1 to 30 The aerosol-generating article 1 comprises an aerosol-generating substrate 11 and a functional segment 12 .

[0067] The functional section 12 is disposed at one end of the aerosol generating substrate 11 along the first direction, and the functional section 12 at least includes a cooling section 121 for reducing the temperature of the aerosol inlet.

[0068] The functional segment 12 is arranged at one end of the aerosol generating matrix 11 along the first direction, that is, the aerosol generating matrix 11 and the functional segment 12 are respectively located at the two ends of the aerosol generating product 1, wherein the aerosol generating matrix 11 is the far lip end of the aerosol generating product 1, and the functional segment 12 is the near lip end of the aerosol generating product 1.

[0069] The proximal lip end refers to the end of the aerosol generating article 1 that is close to the user when the user is using the aerosol generating article 1 , and the distal lip end refers to the end of the aerosol generating article 1 that is away from the user when the user is using the aerosol generating article 1 .

[0070] The functional section 12 at least includes a cooling section 121 for reducing the temperature of the aerosol at the inlet. The functional section 12 may also include a filtering section 122 for filtering the aerosol, and the cooling section 121 is disposed between the aerosol generating substrate 11 and the filtering section 122.

[0071] It should be noted that the filter section 122 is used to filter the aerosol. It is understandable that since the aerosol flows through the filter section 122, the filter section 122 also has the function of further cooling the aerosol.

[0072] Of course, the functional segment 12 may also have the functions of supporting and / or filtering and / or adjusting the suction resistance.

[0073] The aerosol-generating article 1 relies on the aerosol-generating substrate 11 to generate aerosol, and the functional section 12 is not used to generate aerosol.

[0074] In some embodiments, see Figure 29 to Figure 30The aerosol generating product 1 further comprises a wrapping layer 13, which wraps around the outer peripheral side of the functional segment 12 and the aerosol generating substrate 11. The wrapping layer 13 provides installation space and protection for the aerosol generating substrate 11 and the functional segment 12, reduces the probability of damage to the aerosol generating substrate 11 and the functional segment 12, and the heat generated by the aerosol generating substrate 11 when heated will not be directly transferred to the user, thereby increasing the reliability of the aerosol generating product 1.

[0075] Among them, the wrapping layer 13 wrapped around the outer peripheral side of the aerosol generating matrix 11 and the functional segment 12 can be the wrapping layer 13 wrapped around the entire outer peripheral side of the aerosol generating matrix 11 and the functional segment 12, or the wrapping layer 13 wrapped around part of the outer peripheral side of the aerosol generating matrix 11 and the functional segment 12.

[0076] It is understandable that the material of the wrapping layer 13 has a certain structural strength to reduce the probability of deformation of the aerosol generating article 1 due to airflow pressure during use.

[0077] The specific material of the wrapping layer 13 is not limited, such as one or more combinations of fiber paper, metal foil, metal foil composite fiber paper, PE (Polyethylene), polyethylene composite fiber paper, PBAT (Poly (butyleneadipate-co-terephthalate, poly (butylene adipate-co-terephthalate)) and the like.

[0078] It should be noted that, when the wrapping layer 13 wraps the entire outer circumference of the functional segment 12, the user can directly hold the wrapping layer 13 in the mouth to inhale the aerosol; when the wrapping layer 13 wraps part of the outer circumference of the functional segment 12, the user can directly hold the part of the functional segment 12 extending beyond the wrapping layer 13 in the mouth to inhale the aerosol. Of course, the user can also provide a nozzle outside the functional segment 12 to inhale the aerosol through the nozzle.

[0079] The present application embodiment provides an aerosol generating matrix, please refer to Figures 1 to 30 The aerosol generating matrix 11 includes at least two units, each unit is one of a medium monomer 111, a heat generating monomer 112 or a functional monomer 113, at least one unit is a medium monomer 111, and each unit is connected into an integrated structure.

[0080] The medium unit 111 is used to generate aerosol.

[0081] The heat-generating unit 112 can be used to heat the medium unit 111 to generate aerosol.

[0082] The functional monomer 113 is, for example, a moisture-proof layer or a flavoring monomer. The moisture-proof layer can effectively isolate external moisture from entering the aerosol generating matrix 11, reduce moisture absorption, and prevent the generated aerosol from heating up. The flavoring monomer can be used to enhance, replenish, or enrich the flavor of the aerosol.

[0083] Each unit is one of the medium monomer 111, the heat-generating monomer 112 or the functional monomer 113, and at least one unit is the medium monomer 111. That is to say, the aerosol generating matrix 11 includes at least one medium monomer 111 for generating aerosol, and then forms different combinations with other units according to needs, that is, any combination of at least one medium monomer 111 and one or more other units is realized, which can realize the combination changes of different flavors and improve the user experience.

[0084] Specifically, the aerosol generating matrix 11 may be composed of a plurality of dielectric monomers 111, or may be composed of a dielectric monomer 111 and a heating monomer 112, or may be composed of a dielectric monomer 111 and a functional monomer 113, or may be composed of a dielectric monomer 111, a heating monomer 112, and a functional monomer 113. The number of each monomer may be one or more.

[0085] The embodiment of the present application provides an aerosol generating matrix 11. The embodiment of the present application provides an aerosol generating matrix 11. The aerosol generating matrix 11 includes at least two units, each unit is one of a medium monomer 111, a heat generating monomer 112 or a functional monomer 113, at least one unit is a medium monomer 111, and each unit is an integrated structure. That is to say, by setting a combination of multiple units, the composition of the aerosol generating matrix 11 can be regulated, thereby improving the plasticity of the aerosol generating matrix 11. For example, by setting a plurality of medium monomers 111 with different materials, a combination of different flavors can be achieved, which is conducive to improving the user's use experience and the richness of the aerosol. By setting a combination of the medium monomer 111 and the heat generating monomer 112, it is conducive to improving the heating efficiency and reducing the waiting time. By setting a combination of the medium monomer 111 and the functional monomer 113, the functional monomer 113 is, for example, a flavoring material or a moisture-proof monomer, which is further conducive to improving the richness of the aerosol and the consistency of the taste, thereby improving the user's use experience.

[0086] In the related art, the smoking materials of smoking products are, for example, granular, shredded tobacco, thin sheets, etc., which are formed by integral filling, rolling or gathering. When shredded tobacco smoking products are matched with a central heat source, the central material of the smoking products tends to move upward, resulting in "shred blocking". Granular smoking products are prone to poor uniformity of filling particle shape during production and processing, and the seals are prone to fall off, moisture absorption, and sticking and agglomeration with utensils during use.

[0087] The units of the aerosol generating matrix 11 provided in the embodiment of the present application are of an integrated structure, so as to improve the uniformity of the density of the aerosol generating matrix 11 and improve the stability of aerosol release and suction. In addition, the mass of the medium monomer 111 of the integrated structure is relatively uniform. When the heating element heats the medium monomer 111, it will not squeeze the structure around the medium monomer 111, so that the medium monomer 111 maintains a relatively uniform matrix density. Furthermore, the medium monomer 111 of the integrated structure is not easy to stick to the aerosol generating device, agglomerate, etc.

[0088] In addition, each unit is an integrated structure, which can effectively solve the problem of compounding or splicing each unit, shorten the process route, and reduce the quality fluctuation of the aerosol generating matrix 11. No additional adhesive is required, which is more conducive to ensuring the taste of the aerosol generating matrix 11.

[0089] In some embodiments, each unit is a unitary structure formed by a co-extrusion process.

[0090] Each unit is an integrated structure formed by a co-extrusion process, which can effectively solve the problem of compounding or splicing multiple units, shorten the process route, and reduce the quality fluctuation of the aerosol generating matrix 11. In addition, the co-extrusion process is simple, low-cost, and does not require the use of additional adhesives, which is more conducive to ensuring the taste of the aerosol generating matrix 11.

[0091] Each unit is an integrated structure formed by a co-extrusion process. The units can be directly extruded at the same time, that is, directly integrally formed, or one layer can be formed first and then co-extruded with another layer.

[0092] The specific components of the medium monomer 111 are not limited here. For example, in one embodiment, the medium monomer 111 may include plant components, auxiliary components, smoke-generating agent components, adhesive components, and flavor components.

[0093] The plant component is used to generate an aerosol when heated. The auxiliary component is used to provide a skeleton support for the plant component. The smoke-generating agent component is used to generate smoke when heated. The adhesive component is used to bond the various raw material components. The flavor component is used to provide a characteristic aroma. In this way, the plant component and the smoke-generating agent component can ensure the amount of aerosol generated, while the flavor component can enhance the release of aroma during the inhalation process and enhance the user experience. The auxiliary component can not only improve the fluidity of the mixed material, but also make the medium monomer 111 porous to facilitate the extraction and flow of the aerosol. The adhesive component ensures that the plant component and the auxiliary component etc. constitute a stable mixture to avoid a loose structure.

[0094] Exemplarily, the plant component can be one or more combinations of powders formed after crushing tobacco raw materials, tobacco leaf fragments, tobacco stems, tobacco dust, and flavor plants. Plant components are the core source of flavor. Endogenous substances in plant components can produce physiological satisfaction for users. Endogenous substances such as alkaloids enter the human blood and promote the pituitary gland to produce dopamine, thereby obtaining physiological satisfaction.

[0095] Exemplarily, the auxiliary agent component 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 component, and the inorganic filler also has micropores, which can increase the porosity of the medium monomer 111, thereby increasing the aerosol release rate. 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 component powder, reduce the friction between the plant component powders, make the overall density of the plant component powder distribution more uniform, and can also reduce the pressure required for the extrusion molding process and reduce the wear of the die. The emulsifier includes one or more combinations of polyglycerol fatty acid esters, 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 the flavor substances, and improve the sensory quality of the product.

[0096] Exemplarily, the smoke-generating agent component 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) in one or more combinations.

[0097] Exemplarily, the adhesive component is in close contact with the interface of the component raw materials by wetting, generating intermolecular attraction, thereby playing a role in bonding the component raw materials, such as powders, liquids, etc. The adhesive component 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 medium monomer 111 and is harmless to the human body.

[0098] Exemplarily, the flavor component is used to provide a characteristic aroma, such as hay aroma, roasted sweet aroma, solid or liquid substances of nicotine. The flavor component may include one or more combinations of tobacco or other plants, flavor plant extracts, extracts, essential oils, and absolute oils; the flavor component may include unit flavor substances, such as one or more combinations of megastigmatriene, neophytadiene, geraniol, nerol, etc.

[0099] In the embodiment of the present application, the first direction does not specifically refer to the direction in which the outer contour of the aerosol-generating substrate 11 is the longest. Specifically, the direction in which the aerosol-generating product 1 is inserted into the storage bin and the direction in which the aerosol-generating product 1 is taken out of the storage bin are both parallel to the first direction. The length of the aerosol-generating substrate 11 along the first direction may be longer, shorter, or the same as the length in other directions.

[0100] For example, when the appearance of the aerosol generating substrate 11 is cylindrical, the first direction is the axial direction of the aerosol generating substrate 11. It should be noted that even when the axial length of the aerosol generating substrate 11 is smaller than its diameter, the first direction of the aerosol generating substrate 11 is still the axial direction. For another example, when the appearance of the aerosol generating substrate 11 is a rectangular parallelepiped, the first direction is still the direction defined above, that is, the direction in which the containing chamber takes in and out the aerosol generating product 1. The first direction of the aerosol generating substrate 11 can be any direction of the length, width, and height of the rectangular parallelepiped.

[0101] In one embodiment, the multiple units are independent of each other, which means that each unit is manufactured separately.

[0102] In some embodiments, all the units are dielectric monomers 111 , and at least adjacent dielectric monomers 111 are made of different materials.

[0103] The material of the dielectric monomer 111 includes components and ratios of the components.

[0104] The number of units in this embodiment is not limited here, that is, the number of dielectric monomers 111 can be selected according to needs, for example, it can be 2, 3, 4, 5, 6, 7, 8, 9 or 10.

[0105] At least the materials of adjacent dielectric monomers 111 are different, the materials of all dielectric monomers 111 may be different, or the materials of some non-adjacent dielectric monomers 111 may be the same.

[0106] The different materials of adjacent medium monomers 111 can realize the combination of different flavors, which is beneficial to improving the user experience and the richness of the aerosol.

[0107] In some embodiments, see Figures 1 to 30 At least a portion of the medium monomer 111 has at least one air passage hole 11 a inside, and the air passage hole 11 a passes through at least one end of the medium monomer 111 along the first direction.

[0108] At least some of the medium monomers 111 have at least one air passage hole 11 a inside. Some of the medium monomers 111 may have at least one air passage hole 11 a inside, or all of the medium monomers 111 may have at least one air passage hole 11 a inside.

[0109] The medium monomer 111 has at least one air passage hole 11 a inside. The medium monomer 111 may have one air passage hole 11 a inside, or may have multiple air passage holes 11 a inside.

[0110] In some embodiments, the air passage holes 11 a pass through the same end of the medium monomer 111 along the first direction, and the other end is closed.

[0111] In some other embodiments, a portion of the air passage holes 11 a passes through one end of the medium monomer 111 along the first direction, and another portion of the air passage holes 11 a passes through the other end of the medium monomer 111 along the first direction.

[0112] In some other embodiments, please refer to Figures 1 to 30 Each airway hole 11a passes through both ends of the medium monomer 111 along the first direction, that is, the airway hole 11a extends along the first direction of the medium monomer 111, and the airflow can flow from one end of the medium monomer 111 through the airway hole 11a to the other end of the medium monomer 111. Preferably, the airway hole 11a is parallel to the central axis of the medium monomer 111.

[0113] Of course, the air passage hole 11 a may also be configured to penetrate the side wall of the medium monomer 111 .

[0114] In some embodiments, the medium monomer 111 has a through hole inside, and the air passage hole 11a is arranged around the through hole. The through hole penetrates at least one end of the medium monomer 111 along the first direction.

[0115] The airway hole 11a and the hole wall of the through hole constitute the inner surface of the medium monomer 111. The airway hole 11a can increase the inner surface area of ​​the medium monomer 111, facilitate heat transfer, and improve heating efficiency. In addition, the medium monomer 111 generates aerosol after heating, and the aerosol is collected in the airway hole 11a and transported to the suction end under the action of the suction negative pressure. The airway hole 11a can reduce the suction resistance of the user and improve the user experience. It should be noted that the suction resistance is positively correlated with the flow resistance of the aerosol. The smaller the flow resistance of the aerosol in the medium monomer 111, the smaller the suction resistance experienced by the user. The greater the flow resistance of the aerosol in the medium monomer 111, the greater the suction resistance experienced by the user.

[0116] It should be noted that the medium monomer 111 is formed with micropores, and the micropores are connected to each other to form a micro-airway connected to the airway hole 11a. In other words, the micro-airway is connected to the airway hole 11a, and since the micro-airway is formed by the connection between the micropores, the micropores are connected to the micro-airway. In addition, it can be understood that the connection between the micropores can be that some of the micropores are connected and some of the micropores are not connected; or all the micropores are connected to each other. For example, in the embodiment where the medium monomer 111 is a particle combination, the gaps between the particles constitute the micropores. The size of the micropores is determined by the gaps between the particles.

[0117] The airway holes 11a and the micro-airways can increase the surface area of ​​the medium monomer 111, facilitate heat transfer, and improve heating efficiency. The medium of the medium monomer 111 releases aerosols when heated, and is collected to the airway holes 11a through the gaps between the wall materials or the micro-airways. The aerosols released by the atomized medium exposed to the airway holes 11a (i.e., the atomized medium located on the inner wall surface of the airway holes 11a) can be directly released to the airway holes 11a. The aerosols between adjacent airway holes 11a can also circulate with each other through the micro-airways and be transported to the suction end under the action of the suction negative pressure.

[0118] It should be noted that the shape of the airway hole 11a is not limited here. For example, on a plane perpendicular to the first direction, the cross-sectional shape of the airway hole 11a includes but is not limited to a circle (such as Figures 1 to 25 ), ellipse, track, polygon (such as Fig.26 ) or a fan, wherein the polygon includes regular or irregular polygons.

[0119] The shape of the airway hole 11a includes the cross-sectional shape of the airway hole 11a and the spatial shape of the airway hole 11a. The cross-sectional shape is a plane perpendicular to the first direction of the medium monomer 111. The cross-sectional shape of the airway hole 11a refers to the shape of a single airway hole 11a cut in a cross section.

[0120] For example, see Fig.26The airway holes 11a on the medium monomer 111 are honeycomb square holes, which can make the airway holes 11a more evenly distributed and the aerosol release fast and uniform.

[0121] Among them, the runway shape refers to: a shape similar to an athletics track, composed of two semicircles and two parallel straight edges alternately connected.

[0122] The cross-sectional shape of the airway hole 11 a refers to the cross-sectional shape of the airway hole 11 a cut along a plane perpendicular to the first direction of the medium monomer 111 .

[0123] Exemplarily, when the shape of the airway hole 11 a is circular, the lateral support strength of the medium monomer 111 can be increased, and the reprocessing performance of the medium monomer 111 can be improved.

[0124] Exemplarily, when the shape of the air passage hole 11 a is a square hole, the heating uniformity of the medium monomer 111 can be improved.

[0125] For example, when the shape of the airway hole 11a is a diamond-shaped hole, the lateral cutting performance of the medium monomer 111 can be improved, and the deformation phenomenon of the medium monomer 111 caused by cutting during the processing can be reduced.

[0126] Exemplarily, when the air passage hole 11 a is in the shape of a fan-shaped hole, the heat transfer path is single, and compared with a multi-path heat transfer method, the service life of the medium monomer 111 can be increased.

[0127] It should be noted that the size of the air passage hole 11 a may vary with the size of the end surface of the dielectric monomer 111 .

[0128] It should be noted that the shape of the dielectric monomer 111 is not limited here. For example, on a plane perpendicular to the first direction, the cross-sectional shape of the dielectric monomer 111 includes but is not limited to a circle (eg Figure 3 to Figure 4 , Figures 9 to 12 ), ellipse, racetrack, polygon or fan-shaped, wherein the polygon includes regular or irregular polygon.

[0129] In some embodiments, see Figures 1 to 20 , multiple units are installed one by one along the inner and outer directions. In this way, it is easy to combine different heating methods, and each unit can release aerosol separately as the heating time goes by. For example, the central heating method transfers heat from the center to the edge over time, or the circumferential heating method transfers heat from the edge to the center over time. The flavor of the aerosol released by the unit can be adjusted, giving users a new smoking experience.

[0130] It should be noted that the inside refers to the direction close to the center of the aerosol generating substrate 11, and the outside is opposite to the inside.

[0131] In some embodiments, see Figures 1 to 10 , the number of units is two. That is, the aerosol generating substrate 11 is composed of two unit structures.

[0132] See also Figures 9 and 10 , both units are dielectric monomers 111. The inner dielectric monomer 111 contains a phase change material, which can be gasified after being heated.

[0133] The dielectric materials of the inner and outer dielectric monomers 111 are different, wherein the outer dielectric monomer 111 includes, for example, materials such as plant components, auxiliary components, smoke-generating agent components, adhesive components, and flavor components, and an airway hole 11a is provided inside the outer dielectric monomer 111, which is conducive to the effective release of the aerosol generated by heating. The inner dielectric monomer 111 includes a phase change material, and in addition, the inner dielectric monomer 111 also includes materials such as plant components, auxiliary components, smoke-generating agent components, adhesive components, and flavor components. By adding part of the phase change material to the inner dielectric monomer 111, an airway can be generated while generating an aerosol because the phase change material can be vaporized after being heated.

[0134] An air passage hole 11a may be provided inside the inner medium monomer 111, which is more conducive to the uniform extraction of the effective substances generated by heating and gasification.

[0135] It is understandable that in other embodiments, the airway hole 11a (not shown) may not be provided inside the inner medium monomer 111. The air holes are formed by heating and vaporization, which can adjust the suction resistance of the medium monomer 111 and enrich and supplement the aroma of the aerosol and the amount of aerosol generated.

[0136] Exemplarily, the phase change material changes from a solid state to a gaseous state when heated. That is, the phase change material undergoes a physical state change from a solid state to a gaseous state when heated.

[0137] It should be understood that phase change materials can undergo solid-liquid-gas phase change or solid-gas phase change.

[0138] In this embodiment, the phase change material is heated and vaporized, so that the location of the phase change material becomes a hole, that is, the hole is formed during the use of the aerosol generating matrix 11. In this way, before the aerosol generating matrix 11 is heated, the location of the phase change material is sealed, and after the aerosol generating matrix 11 is heated, the phase change material is heated and vaporized, and the aerosol generating matrix 11 forms holes, increasing the number of airway holes 11a and / or through holes, and ensuring the suction effect.

[0139] In one embodiment, the phase change (gasification) temperature of the phase change material is 80°C to 160°C. Exemplarily, the phase change temperature of the phase change material is 80°C, 100°C, 110°C, 120°C, 150°C or 160°C, etc. In other words, the phase change material begins to change when it is heated to above 80°C. During the phase change process of the phase change material, the phase change material gradually gasifies to generate air channels, thereby improving the transmission efficiency.

[0140] In some embodiments, the phase change material may also include flavors and fragrances. The flavors and fragrances are used to provide characteristic aromas. In this way, the phase change material can increase the aroma of the aerosol and make the taste richer.

[0141] In the related art, during the long-term heating process of the aerosol generating matrix, the temperature between the aerosol generating matrix and the heating element is concentrated due to the central or circumferential heating method, which makes it easy for the aerosol generated by the aerosol generating matrix to contain impurities that cannot be eliminated. Most of the existing heating elements are located inside the device, and there is a problem of cleaning after the aerosol generating matrix and the heating element are attached. The existing heating methods all have the problem of low heating efficiency or low thermal conductivity efficiency. From the time consumers "want to smoke" to "smoke", they need to wait for preheating time, and they cannot smoke immediately, which greatly affects the smoking experience.

[0142] The aerosol generating substrate 11 of the embodiment of the present application includes two units. Figures 1 to 6 One of the two units is a dielectric unit 111 , and the other is a heat generating unit 112 .

[0143] For example, see Figures 1 to 8 , taking two units mounted one by one in the inner and outer directions as an example, in some embodiments, refer to Figures 1 to 6 The outer layer may be a medium monomer 111 for generating aerosol. The medium monomer 111 may be provided with an airway hole 11a to facilitate the effective release of the generated aerosol. The shape of the medium monomer 111 may be a racetrack, a column, etc. The inner layer is a heating element, which may be a sheet, a needle, a column, etc. The heating element is tightly fitted to the medium monomer 111 to achieve sufficient heating, so that the aerosol in the medium monomer 111 is quickly and fully released.

[0144] That is to say, the heating element 112 and the medium element 111 are mounted one by one along the inner and outer directions, so that the heating element and the medium element 111 can be closely fitted to achieve sufficient heating, so that the aerosol in the medium element 111 is quickly and fully released.

[0145] In some other embodiments, see Figures 7 and 8 , the outer layer may be a heating unit 112, and the inner layer may be a dielectric unit 111. The dielectric unit 111 and the heating unit 112 are mounted one by one along the inner and outer directions, which can effectively increase the heating area and improve the heating efficiency.

[0146] Exemplarily, the number of units is two. Both units are medium monomers 111. The two medium monomers 111 are made of different materials, which can achieve different flavor combinations, which is beneficial to improving the user experience and the richness of the aerosol.

[0147] In some embodiments, see Figures 9 and 10 The two medium monomers 111 are made of the same material, for example, tobacco material, but the microstructures of the two medium monomers 111 are different. One of the medium monomers 111 has a loose structure, which allows the front smoke to be released quickly. The other medium monomer 111 has a dense structure, which is more conducive to heat transfer, reduces the attenuation of the middle and rear smoke, and improves the consistency of the smoke volume and taste.

[0148] In some embodiments, one of the two units is a medium unit 111, and the other is a functional unit 113, and the functional unit 113 is a flavoring material. The medium unit 111 is used to provide sufficient aerosol generation, and the flavoring material is used to enrich the tobacco flavor. The two different smoke streams converge above the consumables, which is beneficial to the consistency of the smoke volume and tobacco flavor, and enhances the consumer experience.

[0149] In some embodiments, see Figures 11 to 20 , the number of units is three, that is, the aerosol generating matrix 11 is composed of three units.

[0150] The three units are an integrated structure formed by a co-extrusion process. The three units can be directly extruded at the same time, that is, directly integrally formed. Alternatively, the inner layer can be formed first, and then co-extruded with the middle layer and the outer layer. Alternatively, the inner layer and the middle layer can be formed separately or integrally, and then co-extruded with the outer layer.

[0151] In some embodiments, see Figure 19 to Figure 20 All three units are medium monomers 111, and all three units include materials such as plant components, auxiliary components, smoke-generating agent components, adhesive components and flavor components. All three units are medium monomers 111 with different formulas, which can achieve combination changes of different flavors, which is beneficial to improving the user experience and the richness of the aerosol.

[0152] In some embodiments, all three units are dielectric monomers 111 , and the dielectric monomers 111 located in the middle layer contain phase change materials, which can be vaporized after being heated.

[0153] By setting the medium monomer 111 located in the middle layer to include a phase change material, the phase change material can be vaporized after being heated, and the phase change material vaporizes when heated, so that the place where the phase change material is located becomes a hole, that is, the hole is formed during the suction and use of the aerosol generating matrix 11. In this way, before the aerosol generating matrix 11 is used and heated, the place where the phase change material is located is sealed. After the aerosol generating matrix 11 is heated, the phase change material is heated and vaporized, and the aerosol generating matrix 11 forms holes, increasing the number of airway holes 11a and / or through holes to ensure the suction effect. After being heated, the amount of aerosol generated is effectively increased, and the aerosol release efficiency is adjusted in conjunction with the design of the airway hole 11a.

[0154] In some embodiments, the phase change material may also include flavors and fragrances. The flavors and fragrances are used to provide characteristic aromas. In this way, the phase change material can increase the aroma of the aerosol and make the taste richer.

[0155] It is understandable that in other embodiments, the airway hole 11a (not shown) may not be provided inside the medium monomer 111 of the middle layer. The airway hole 11a and / or through hole are formed by heating and vaporization, which can adjust the suction resistance of the medium monomer 111 and is used to enrich and supplement the aroma of the aerosol and the amount of aerosol generated.

[0156] Of course, in other embodiments, the inner dielectric monomer 111 and / or the outer dielectric monomer 111 may also include a phase change material.

[0157] In some embodiments, see Figures 11 to 16 The number of units is three. Along the inner and outer directions, the three units are a heat generating unit 112, a dielectric unit 111 and a functional unit 113, respectively. The functional unit 113 is a moisture-proof unit.

[0158] The moisture-proof monomer is, for example, a moisture-proof layer. The moisture-proof layer can reduce the probability of each unit inside the moisture-proof layer contacting the outside air, improve the waterproof and moisture-proof performance, reduce the water loss of the aerosol generating matrix 11, and to a certain extent prevent the aerosol generating matrix 11 from being moldy and deteriorating in taste due to moisture during transportation, storage, shelf life, etc. It can also prevent the generated aerosol from getting hot. During the use of the aerosol generating matrix 11, the aerosol generating matrix 11 releases aerosol when heated. In addition, the moisture-proof layer can also reduce the probability of aerosol dissipating to the outside.

[0159] It should be noted that the specific shape of the heating unit 112 is not limited here. For example, on a plane perpendicular to the first direction of the aerosol generating substrate 11, the cross-sectional shape of the heating unit 112 is a strip, a circle, an ellipse, a ring, a sector, an arc, a sawtooth or a polygon.

[0160] Exemplarily, the heat generating unit 112 is in the form of a sheet (eg Fig.13and Fig.14 ), needle-shaped (such as Fig.11 and Fig.12 ), columnar, cross-shaped (such as Fig.15 and Fig.16 ), "M" shape or radial shape.

[0161] The heating unit 112 is embedded in the medium unit 111 and fits tightly with the medium unit 111 to achieve sufficient heating, so that the aerosol in the medium unit 111 is released quickly and fully, avoiding problems such as loose fitting, uneven heating and cleaning.

[0162] In some embodiments, see Figure 17 to Figure 18 The number of units is three. Along the inner and outer directions, the three units are a dielectric monomer 111, a heat generating monomer 112 and a dielectric monomer 111 in sequence. The materials of the two dielectric monomers 111 are different.

[0163] Along the inner and outer directions, the three units are the dielectric monomer 111, the heat generating monomer 112 and the dielectric monomer 111 in sequence, that is, the dielectric monomer 111, the heat generating monomer 112 and the dielectric monomer 111 are set one by one along the inner and outer directions.

[0164] The two medium monomers 111 are made of different materials, which can achieve different flavor combinations, which is beneficial to improving the user experience and the richness of the aerosol.

[0165] The heat generating monomer 112 is located between the two layers of medium monomers 111. The two layers of medium monomers 111 are heated at the same time, which is beneficial to accelerate the aerosol generation rate, promote the rapid release of effective components in the medium monomers 111, and improve the consistency of the puff-by-puff release amount.

[0166] In some embodiments, see Figures 21 to 28 , a plurality of the units are spliced ​​one by one along the circumferential direction.

[0167] In this way, it is convenient to combine different heating methods, so that each unit can release aerosol separately as the heating time goes by, and the effect of directional selective release of aerosols of different flavors can be achieved. It can also avoid the odor generated by repeated heating of the aerosol generating matrix 11, ensuring that the aerosol in each puff is fresh, thereby improving the consistency of puffing.

[0168] For example, it can be used in conjunction with a zoned heating device to heat the medium monomer 111 in different areas separately to achieve the effect of directional selective release of aerosols of different flavors. The zoned heating device can be, for example, a laser heating device, in which the laser emitting element and the medium monomer 111 can rotate relative to each other, or a multi-laser emitting device to achieve zoned heating.

[0169] Exemplarily, in one embodiment, the heater includes a plurality of independently controlled heating elements, which are arranged at intervals around the aerosol generating substrate 11, and each heating element heats a corresponding medium monomer 111. The heating elements selectively heat the medium monomer 111, thereby achieving the directional selective release of aerosols of different medium monomers 111, for example, achieving the effect of directional selective release of aerosols of different flavors, and avoiding the odor caused by repeated heating, thereby ensuring that the aerosol in each puff is fresh, and improving the puffing consistency.

[0170] Each unit is an integrated structure formed by a co-extrusion process, and can be formed separately and then spliced ​​into one, or formed in one piece at a time. The advantage of this is that the aerosol generating matrix 11 has strong plasticity, is more conducive to processing, and the process is simpler and easier to control.

[0171] The aerosol generating substrate 11 of the embodiment of the present application includes two units. Figure 21 to Figure 22 One of the two units is a dielectric unit 111 , and the other is a heat generating unit 112 .

[0172] For example, two units are spliced ​​one by one along the circumferential direction. In some embodiments, Fig.11 As shown, the aerosol generating matrix 11 is columnar, and the medium monomer 111 and the heating monomer 112 are of the same size, that is, the central angles corresponding to the two units are both 180°, one side is the medium monomer 111, and the other side is the heating monomer 112, and the cross-sections of the two along the first direction are fitted together, so that the contact area between the heating monomer 112 and the medium monomer 111 can be large, that is, the heating area of ​​the heating monomer 112 is increased, which is conducive to providing more energy, allowing the medium monomer 111 to quickly emit smoke, and is conducive to processing and molding.

[0173] Of course, in other embodiments, the sizes of the dielectric monomer 111 and the heat generating monomer 112 are different, that is, the central angles of the dielectric monomer 111 and the heat generating monomer 112 are different.

[0174] For example, see Figure 23 to Figure 24 The aerosol generating matrix 11 is columnar, and the number of units is two, and the two units are spliced ​​one by one along the circumferential direction. The two units are both medium monomers 111. The two medium monomers 111 are made of different materials, and the cross-sections along the first direction are attached to each other, so that different flavors can be combined and changed, which is conducive to improving the user experience and the richness of the aerosol.

[0175] The two medium monomers 111 are provided with the same macroscopic airway holes 11a, and both sides are heated at the same time, which is conducive to consistency; they can also be heated in different areas to switch between different flavors. Furthermore, the airway holes 11a of the two medium monomers 111 can also be different, such as the airway hole 11a of one medium monomer 111 is a circular hole, and the airway hole 11a of the other medium monomer 111 is a square honeycomb hole, which has the effect of regulating and improving smoke, making the aerosol release more uniform and stable.

[0176] In some embodiments, one of the two units is a medium unit 111, and the other is a functional unit 113, and the functional unit 113 is a flavoring material, and the two units are spliced ​​one by one along the circumference. The medium unit 111 is used to provide sufficient aerosol generation, and the flavoring material is used to enrich the tobacco flavor. The two different smoke streams converge above the consumables, which is beneficial to the consistency of the smoke volume and tobacco flavor, and enhances the consumer experience.

[0177] In some embodiments, see Figure 25 to Figure 26 The number of the units is three, and all three units are dielectric monomers 111. One of the three dielectric monomers 111 contains a phase change material, and the phase change material can be gasified after being heated.

[0178] The phase change material can be vaporized after being heated, and the phase change material vaporizes when heated, so that the place where the phase change material is located becomes a hole, that is, the hole is formed during the suction and use of the aerosol generating matrix 11. In this way, before the aerosol generating matrix 11 is heated, the place where the phase change material is located is sealed. After the aerosol generating matrix 11 is heated, the phase change material is heated and vaporized, and the aerosol generating matrix 11 forms holes, increasing the number of airway holes 11a and / or through holes to ensure the suction effect. After being heated, the amount of aerosol generated is effectively increased, and the design of the airway hole 11a is combined to adjust the aerosol release efficiency.

[0179] In some embodiments, the phase change material may also include flavors and fragrances. The flavors and fragrances are used to provide characteristic aromas. In this way, the phase change material can increase the aroma of the aerosol and make the taste richer.

[0180] One of the three units is a functional monomer 113, and the functional monomer 113 is a flavoring material. The flavoring material is used to enrich the aroma of the tobacco.

[0181] In some embodiments, the number of the units is three, one of which is a functional monomer 113, and the functional monomer 113 is a flavoring material.

[0182] Specifically, the aerosol generating matrix 11 is columnar, one of the three units is a functional monomer 113, the functional monomer 113 is a flavoring material, the other two units are medium monomers 111, one of the two medium monomers 111 contains a phase change material, and the three units are provided with airway holes 11a, and the airway holes 11a of each unit are the same, and all have circular holes, which have the function of adjusting the inhalation resistance. By selecting different materials for the three units, the medium monomer 111 is used to provide sufficient aerosol generation, and the flavoring material is used to enrich the tobacco flavor. By matching the heating body and heating at the same time, three different aerosols are released, and after reorganization and mixing, they are inhaled by consumers, so that the overall release is uniform, the flavor is full, and the consistency is good.

[0183] In some embodiments, see Fig.26 The airway holes 11a on the three units are honeycomb square holes, the hole shape distribution is more uniform, and the aerosol release is fast and uniform.

[0184] In some embodiments, see Figure 27 to Figure 28 The number of the units is four, and the four units include two dielectric monomers 111 and two heat generating monomers 112, and the dielectric monomers 111 and the heat generating monomers 112 are alternately arranged along the circumferential direction.

[0185] By arranging two medium monomers 111 and two heating monomers 112, the medium monomers 111 and the heating monomers 112 are alternately arranged along the circumferential direction. The medium monomers 111 and the heating monomers 112 can be cross-formed, so that when the volume of the heating monomers 112 is the same, the contact area between the medium monomers 111 and the heating monomers 112 is doubled, that is, the heating area is doubled, thereby improving the aerosol generation rate and heating efficiency of the medium monomers 111.

[0186] It should be noted that the sizes of the four units can be set to be consistent, for example, the central angles of the four units are all 90°. Of course, the sizes of the four units can also be set to be inconsistent.

[0187] In some embodiments, see Figure 29 to Figure 30 , multiple units are assembled one by one along the inner and outer directions, and the functional section 12 and the aerosol generating matrix 11 are an integrated structure.

[0188] In this way, the raw material combination ratios of each unit are different, and different flavor combinations can be achieved to enrich the user experience, and the internal structures can be the same or different.

[0189] The functional section 12 and the aerosol generating matrix 11 are an integrated structure, which can reduce assembly time, improve assembly efficiency, and increase production efficiency.

[0190] In some embodiments, see Figure 29 to Figure 30The aerosol generating product 1 further comprises a wrapping layer 13, which wraps around the outer periphery of the functional segment 12 and the aerosol generating matrix 11, and the wrapping layer 13, the aerosol generating matrix 11 and the functional segment 12 are an integrated structure.

[0191] The wrapping layer 13, the aerosol generating matrix 11 and the functional segment 12 are an integrated structure, which can further reduce the assembly time, improve the assembly efficiency and increase the production efficiency.

[0192] In some embodiments, see Fig.30 The functional section 12 includes a cooling section 121 and a filtering section 122 located at one end of the cooling section 121 away from the aerosol generating substrate 11. The aerosol generating substrate 11, the cooling section 121 and the filtering section 122 are an integrated structure.

[0193] The aerosol generating matrix 11, the cooling section 121 and the filtering section 122 are an integrated structure, which can further reduce the assembly time, improve the assembly efficiency, and improve the production efficiency.

[0194] In some embodiments, the wrapping layer 13, the aerosol-generating substrate 11 and the functional segment 12 are an integral structure formed by a co-extrusion process.

[0195] The wrapping layer 13, the aerosol generating matrix 11 and the functional segment 12 are an integrated structure formed by a co-extrusion process, which can effectively shorten the process route and reduce the quality fluctuation of the aerosol generating product 1. In addition, the co-extrusion process is simple and low-cost, which is more conducive to ensuring the taste of the aerosol generating product 1.

[0196] Sixteen specific embodiments are briefly introduced below with reference to the accompanying drawings.

[0197] First embodiment

[0198] See also Figure 1 and Figure 2 In this embodiment, the number of units of the aerosol generating matrix 11 is two. The two units are mounted one by one along the inner and outer directions. The outer layer is a medium monomer 111, and the inner layer is a heating element. The medium monomer 111 is used to generate aerosol. The medium monomer 111 may be provided with an airway hole 11a to facilitate the effective release of the generated aerosol. The heating element and the medium monomer 111 are closely attached to achieve sufficient heating, so that the aerosol in the medium monomer 111 is quickly and fully released.

[0199] The medium unit 111 has an air passage hole 11 a inside, and the cross section of the air passage hole 11 a is circular.

[0200] The dielectric unit 111 is in a racetrack shape, and the heat generating unit 112 is in a sheet shape.

[0201] That is to say, the heating element 112 and the medium element 111 are mounted one by one along the inner and outer directions, so that the heating element and the medium element 111 can be closely fitted to achieve sufficient heating, so that the aerosol in the medium element 111 is quickly and fully released.

[0211] Sixth embodiment

[0212] See also Fig.11 and Fig.12 In this embodiment, the number of units is three, that is, the aerosol generating matrix 11 is composed of three units. Along the inner and outer directions, the three units are the heat generating unit 112, the medium unit 111 and the functional unit 113, and the functional unit 113 is a moisture-proof unit.

[0213] The medium unit 111 has an air passage hole 11 a inside, and the cross section of the air passage hole 11 a is circular.

[0214] The moisture-proof monomer is, for example, a moisture-proof layer. The moisture-proof layer can reduce the probability of each unit inside the moisture-proof layer contacting the outside air, improve the waterproof and moisture-proof performance, reduce the water loss of the aerosol generating matrix 11, and to a certain extent prevent the aerosol generating matrix 11 from being moldy and deteriorating in taste due to moisture during transportation, storage, shelf life, etc. It can also prevent the generated aerosol from getting hot. During the use of the aerosol generating matrix 11, the aerosol generating matrix 11 releases aerosol when heated. In addition, the moisture-proof layer can also reduce the probability of aerosol dissipating to the outside.

[0218] Eighth embodiment

[0219] See also Fig.15 and Fig.16 In this embodiment, the structure of the aerosol generating substrate 11 is substantially the same as that of the sixth embodiment, and the main differences include: in this embodiment, the shape of the medium monomer 111 is cylindrical, and the heat generating monomer 112 is in the shape of a "cross".

[0220] Ninth embodiment

[0221] See also Fig.17 and Fig.18 In this embodiment, the structure of the aerosol generating matrix 11 is substantially the same as that of the sixth embodiment, and the main differences include: in this embodiment, the number of units is three, and along the inside-outside direction, the three units are respectively a medium monomer 111, a heat generating monomer 112 and a medium monomer 111, and the materials of the two medium monomers 111 are different.

[0222] Along the inner and outer directions, the three units are the dielectric monomer 111, the heat generating monomer 112 and the dielectric monomer 111 in sequence, that is, the dielectric monomer 111, the heat generating monomer 112 and the dielectric monomer 111 are set one by one along the inner and outer directions.

[0223] The two medium monomers 111 are made of different materials, which can achieve different flavor combinations, which is beneficial to improving the user experience and the richness of the aerosol.

[0224] The heat generating monomer 112 is located between the two layers of medium monomers 111. The two layers of medium monomers 111 are heated at the same time, which is beneficial to accelerate the aerosol generation rate, promote the rapid release of effective components in the medium monomers 111, and improve the consistency of the puff-by-puff release amount.

[0225] In this embodiment, the heat generating unit 112 is ring-shaped.

[0226] Tenth embodiment

[0227] See also Fig.19 and Fig. 20 In this embodiment, the structure of the aerosol generating substrate 11 is substantially the same as that of the sixth embodiment, and the main differences include: in this embodiment, the three units are all medium monomers 111.

[0228] In some embodiments, all three units are medium monomers 111, and all three units include materials such as plant components, auxiliary components, smoke-generating agent components, adhesive components and flavor components. All three units are medium monomers 111 with different formulations, which can achieve combination changes of different flavors, which is beneficial to improving the user experience and the richness of the aerosol.

[0229] In some embodiments, all three units are dielectric monomers 111 , and the dielectric monomers 111 located in the middle layer contain phase change materials, which can be vaporized after being heated.

[0230] By setting the medium monomer 111 located in the middle layer to include a phase change material, the phase change material can be vaporized after being heated, and the phase change material vaporizes when heated, so that the place where the phase change material is located becomes a hole, that is, the hole is formed during the suction and use of the aerosol generating matrix 11. In this way, before the aerosol generating matrix 11 is used and heated, the place where the phase change material is located is sealed. After the aerosol generating matrix 11 is heated, the phase change material is heated and vaporized, and the aerosol generating matrix 11 forms holes, increasing the number of airway holes 11a and / or through holes to ensure the suction effect. After being heated, the amount of aerosol generated is effectively increased, and the aerosol release efficiency is adjusted in conjunction with the design of the airway hole 11a.

[0231] In some embodiments, the phase change material may also include flavors and fragrances. The flavors and fragrances are used to provide characteristic aromas. In this way, the phase change material can increase the aroma of the aerosol and make the taste richer.

[0232] It is understandable that in other embodiments, the airway hole 11a (not shown) may not be provided inside the medium monomer 111 of the middle layer. The airway hole 11a and / or through hole are formed by heating and vaporization, which can adjust the suction resistance of the medium monomer 111 and is used to enrich and supplement the aroma of the aerosol and the amount of aerosol generated.

[0233] Of course, in other embodiments, the inner dielectric monomer 111 and / or the outer dielectric monomer 111 may also include a phase change material.

[0234] Eleventh Embodiment

[0235] See also Fig.21 and Fig. 22 In this embodiment, the number of units of the aerosol generating matrix 11 is two. The two units are spliced ​​one by one along the circumferential direction. The aerosol generating matrix 11 is columnar, and the medium monomer 111 and the heating monomer 112 are of the same size, that is, the central angles corresponding to the two units are both 180°, one side is the medium monomer 111, and the other side is the heating monomer 112, and the cross-sections of the two along the first direction fit together, so that the contact area between the heating monomer 112 and the medium monomer 111 can be large, that is, the heating area of ​​the heating monomer 112 is increased, which is conducive to providing more energy, allowing the medium monomer 111 to quickly emit smoke, and is conducive to processing and molding.

[0236] The medium unit 111 has an air passage hole 11 a inside, and the cross section of the air passage hole 11 a is circular.

[0237] Of course, in other embodiments, the sizes of the dielectric monomer 111 and the heat generating monomer 112 are different, that is, the central angles of the dielectric monomer 111 and the heat generating monomer 112 are different.

[0238] Twelfth Embodiment

[0239] See also Fig.23 and Fig.24 In this embodiment, the structure of the aerosol generating substrate 11 is substantially the same as that of the eleventh embodiment, and the main differences include: in this embodiment, both units are medium monomers 111.

[0240] Thirteenth Embodiment

[0241] See also Fig.25 In this embodiment, the number of units of the aerosol generating matrix 11 is three, and the three units are all medium monomers 111. The three units are spliced ​​one by one along the circumferential direction.

[0242] The medium unit 111 has an air passage hole 11 a inside, and the cross section of the air passage hole 11 a is circular.

[0243] Fourteenth Embodiment

[0244] See also Fig.26 In this embodiment, the structure of the aerosol generating substrate 11 is substantially the same as that of the eleventh embodiment, and the main differences include: in this embodiment, the cross section of the airway hole 11a is a honeycomb square hole.

[0245] The airway holes 11a on the three units are honeycomb square holes, the hole shape distribution is more uniform, and the aerosol release is fast and uniform.

[0246] Fifteenth Embodiment

[0247] See also Fig. 27 and Fig.28 In this embodiment, the number of units of the aerosol generating matrix 11 is four, and the four units include two medium monomers 111 and two heat generating monomers 112, and the medium monomers 111 and the heat generating monomers 112 are alternately arranged along the circumferential direction.

[0248] The medium unit 111 has an air passage hole 11 a inside, and the cross section of the air passage hole 11 a is circular.

[0249] By arranging two medium monomers 111 and two heating monomers 112, the medium monomers 111 and the heating monomers 112 are alternately arranged along the circumferential direction. The medium monomers 111 and the heating monomers 112 can be cross-formed, so that when the volume of the heating monomers 112 is the same, the contact area between the medium monomers 111 and the heating monomers 112 is doubled, that is, the heating area is doubled, thereby improving the aerosol generation rate and heating efficiency of the medium monomers 111.

[0250] It should be noted that the sizes of the four units can be set to be consistent, for example, the central angles of the four units are all 90°. Of course, the sizes of the four units can also be set to be inconsistent.

[0251] Sixteenth Embodiment

[0254] The functional section 12 includes a cooling section 121 and a filtering section 122 located at one end of the cooling section 121 away from the aerosol generating substrate 11 .
