DETAILED DESCRIPTION

[0044] In the description of the embodiments of the present application, it should be noted that the orientation or position relationship indicated by the term "first direction" or the like is based on the attached Figure 2 The orientation or positional relationship shown, these orientation terms are only for the convenience of describing the embodiments of 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 cannot be understood as a limitation on the embodiments of the present application.

[0045] The present application embodiment provides an aerosol generating article 100, see Figures 1 to 10 The aerosol generating article 100 comprises an aerosol generating substrate segment 10 and two stop segments 20, wherein the two stop segments 20 are respectively arranged at opposite ends of the aerosol generating substrate segment 10 along a first direction.

[0046] See also Fig.11 The aerosol generating product 100 is used in conjunction with an aerosol generating device 200 having a heating component 220. Specifically, the heating component 220 heats and atomizes the aerosol generating substrate segment 10 in the aerosol generating product 100 to generate an aerosol for the user to inhale or for use in medicine, beauty, etc.

[0047] There are many heating methods for the heating component 220. For example, the heating methods include central heating and peripheral heating. The central heating method refers to the heating component 220 being inserted into the aerosol generating product 100 to bake and heat the aerosol generating product 100 from the inside to the outside. The peripheral heating method refers to the heating component 220 being arranged at the periphery of the aerosol generating product 100 to bake and heat the aerosol generating product 100 from the outside to the inside. These heating methods can specifically be resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, etc.

[0048] The aerosol generating article 100 may not be provided with a filter segment for contacting the user's mouth, for example, see Fig.11 The aerosol generating device 200 may be provided with a filter 230 and a shell 210 having a suction channel 210a, the filter 230 being connected to the suction channel 210a, and during the user's inhalation process, the aerosol generated by the heated aerosol generating matrix segment 10 enters the user's oral cavity through the suction channel 210a and the filter 230.

[0049] The specific structure of the aerosol generating matrix segment 10 is not limited here. For example, in one embodiment, the aerosol generating matrix segment 10 can be made of the atomizing medium itself, for example, made of the smoke flavoring medium. In other embodiments, the aerosol generating matrix segment 10 can also include a matrix and an atomizing medium disposed on the matrix. The matrix can be, for example, high temperature resistant carbon fiber. In this way, by providing the matrix, the strength of the aerosol generating matrix segment 10 can be improved, and it can also withstand a certain degree of high temperature without generating odor.

[0050] The specific components of the aerosol generating substrate segment 10 are not limited herein. For example, in one embodiment, the aerosol generating substrate segment 10 may include plant components, auxiliary components, smoke generating agent components, adhesive components, and the like.

[0051] In one embodiment, the plant component 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 component is the core source of the flavor of the product. Endogenous substances in the plant component, such as nicotine, enter the human blood through atomization, promote the pituitary gland to produce dopamine, and thus obtain physiological satisfaction.

[0052] In one embodiment, 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 wall material after the plant component is formed, thereby increasing the aerosol release rate.

[0053] 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 particles, reduce the friction between the particles, make the overall density of the particle distribution more uniform, and also reduce the pressure required for mold molding and reduce the wear of the mold.

[0054] Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers 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 products. Emulsifiers (also known as surfactants) can reduce the interfacial tension of water-soluble and water-insoluble components in the mixed system, and form a relatively strong film on the surface of the droplets or form a double electric layer on the surface of the droplets due to the charge given by the emulsifier, preventing the droplets from aggregating with each other and maintaining a uniform emulsion. Emulsifying and homogenizing two immiscible components can improve the consistency of product quality.

[0055] The function of the smoke-generating agent component is to generate a large amount of steam when heated, thereby increasing the amount of smoke of the smoking product. In one embodiment, the smoke-generating agent may include, for example: a monohydric alcohol (such as menthol); a polyhydric alcohol (such as propylene glycol, triethylene glycol, 1,3-butylene glycol and glycerol); an ester of a polyhydric alcohol (such as monoacetin, diacetin or triacetin); a monocarboxylic 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, diacetin mixture, diethyl suberate, triethyl citrate, benzyl benzoate, benzyl phenylacetate, ethyl vanillate, glyceryl tributyrate, lauryl acetate) or one or more combinations thereof.

[0056] In one embodiment, the adhesive component is a natural plant extract, a non-ionized modified viscous polysaccharide, including one or more combinations of tamarind polysaccharide, pullulan, seaweed polysaccharide, locust bean gum, guar gum, and xyloglucan. The adhesive is in close contact with the interface of the product component material by wetting, generating an intermolecular attraction, thereby playing the role of bonding the powder, liquid, etc. of the component material. At the same time, the use of natural plant extracts and non-ionic adhesives can avoid the release of harmful substances such as methanol, formaldehyde, and acrolein caused by colloid modification, thereby improving the safety of the product.

[0057] Exemplarily, the aerosol generating matrix segment 10 can be a particle combination, which is a reconstituted tobacco medium, for example, a reconstituted tobacco medium containing components such as smoke-generating agents and tobacco. The aerosol generating matrix segment 10 is an integrated structure, for example, it can be one of an injection molding structure, a compression molding structure, an extrusion molding structure, a casting molding structure, a compression molding structure, and a 3D printing molding structure. Extrusion molding refers to a processing method in which a raw material mixture is added to an extruder, and the material is pushed forward by the screw through the action between the extruder barrel and the screw, and continuously passes through the head to form various cross-section products or semi-finished products. The aerosol matrix formed by extrusion molding is in the shape of strips.

[0058] Since the aerosol generating matrix segment 10 is a particle combination, it is an integrated medium when the aerosol generating matrix segment 10 is heated and sucked or stops being heated, and is not prone to disintegration and falling off. This solves the problems in the prior art of the thin sheet, filamentary or loose particle aerosol generating matrix segment 10, such as loose sheets, falling of filamentary components and particle components, and difficulty in cleaning.

[0059] In addition, the shape of the aerosol generating substrate segment 10 is not limited. For example, see Figure 3 The aerosol generating matrix segment 10 may be columnar, and the cross-section of the columnar aerosol generating matrix segment 10 may be circular or in other shapes, such as polygonal (including but not limited to triangle, square, prism, etc.), elliptical, runway-shaped or irregular, etc., wherein irregular refers to other symmetrical or asymmetrical shapes other than the shapes listed above.

[0060] See also Figure 3 , Figures 5 to 10 The aerosol generating substrate segment 10 may be an integrally formed structure having at least one third air channel 10a therein, and the third air channel 10a at least runs through at least one of the two opposite ends of the aerosol generating substrate segment 10 along the first direction.

[0061] Figure 3 , Figures 5 to 10 The third air channel 10a runs through the opposite ends of the aerosol generating substrate segment 10 along the first direction. In some embodiments, the third air channel 10a may also only run through one end of the aerosol generating substrate segment 10 along the first direction, while the other end is a closed end.

[0062] Compared with the third air channel 10a penetrating one end of the aerosol generating substrate segment 10 along the first direction, the third air channel 10a penetrating both ends of the aerosol generating substrate segment 10 along the first direction is more conducive to reducing the user's inhalation resistance.

[0063] The number of the third air passage 10a may be one or more.

[0064] The third air passage 10a may be as follows Figure 3 , Figures 5 to 10 The straight airway shown is an airway extending along a straight line, or in other words, the extending direction of the straight airway is a straight line.

[0065] The third air passage 10a may also be a spiral air passage, which is an air passage in which at least part of the region along the extension direction is in a curved shape with a curvature not equal to zero. For example, along the extension direction of the spiral air passage, the spiral air passage may have a structure in which there are both a curved segment with a curvature not equal to zero and a straight segment with a curvature of zero, or may have only a curved segment with a curvature not equal to zero and no straight segment with a curvature of zero. In other words, from the starting point to the end point of the spiral air passage along the extension direction, the spiral air passage may extend in a straight line.

[0066] When there are multiple third air passages 10 a , a portion of the third air passages 10 a may be straight air passages, and another portion of the third air passages 10 a may be spiral air passages.

[0067] The shape of the cross section of the third air channel 10a is not limited. For example, the cross section may be circular, polygonal (including but not limited to triangle, square, prism, etc.), elliptical, racetrack-shaped or irregular-shaped.

[0068] The third air channel 10a can extend the airflow path and increase the flow speed of the airflow in the aerosol generating matrix segment 10, thereby increasing the impact force of the airflow and allowing the aerosol to be evenly mixed, thereby improving the extraction efficiency and uniformity of the aerosol in the aerosol generating matrix segment 10 and enhancing the user's inhalation experience.

[0069] The first direction is the arrangement direction of the two stop segments 20 and the aerosol generating substrate segment 10. The aerosol generating product 100 is inserted into the aerosol generating device 200 along the first direction, and the aerosol generating product 100 is also taken out of the aerosol generating device 200 along the first direction. The length of the aerosol generating substrate segment 10 along the first direction may be longer, shorter, or the same as the length in other directions.

[0070] For example, when the aerosol generating substrate segment 10 has a cylindrical appearance, the first direction is the axial direction of the aerosol generating substrate segment 10. It should be noted that the axial length of the aerosol generating substrate segment 10 may be smaller than its diameter.

[0071] For another example, when the appearance of the aerosol generating matrix segment 10 is a rectangular parallelepiped, the first direction is still the direction defined above, that is, the arrangement direction of the two stop segments 20 and the aerosol generating matrix segment 10, or the direction of taking and placing the aerosol generating product 100 on the aerosol generating device 200. The first direction of the aerosol generating matrix segment 10 can be any direction of the length, width, and height of the rectangular parallelepiped.

[0072] For example, see Figure 2 and Figure 4 The aerosol generating substrate segment 10 and the two stop segments 20 may be cylinders having the same outer diameter and being coaxially arranged, and the first direction is the axial direction of the aerosol generating substrate segment 10 and the two stop segments 20 .

[0073] Please continue reading Figures 2 to 10 , both stopper segments 20 can allow airflow to pass through, specifically, during the heating process of the aerosol-generating substrate segment 10, the external airflow passes through one of the stopper segments 20 to enter the aerosol-generating substrate segment 10, and then carries the aerosol generated by the aerosol-generating substrate segment 10 through the other stopper segment 20 to flow to the outside of the aerosol-generating article 100. The airflow and aerosol flowing out of the aerosol-generating article 100 then pass through the filter 230 and enter the user's oral cavity.

[0074] That is to say, of the two stopper sections 20, one stopper section 20 is located upstream of the aerosol generating matrix section 10 along the airflow direction, and the other stopper section 20 is located downstream of the aerosol generating matrix section 10 along the airflow direction. Since the aerosol generating matrix section 10 will shrink and deform to a certain extent during the heating process, the stopper section 20 located upstream can block the aerosol generating matrix section 10 to prevent the shrinking and deformed aerosol generating matrix section 10 from loosening and falling off, while the stopper section 20 located downstream can better prevent the aerosol generating matrix section 10 from moving or sliding off during the suction process, that is to say, both stopper sections 20 can play a stopping role.

[0075] In addition, the stop section 20 located downstream can also provide a certain suction resistance to better prevent the aerosol-generating product 100 from causing suction voids due to too small suction resistance and affecting the suction experience. In addition, the stop section 20 located downstream can also play a certain cooling effect on the aerosol.

[0076] It should be noted that the aerosol generating article 100 generates aerosol by means of the aerosol generating substrate segment 10 , and the stop segment 20 does not generate aerosol.

[0077] The two stop segments 20 may be made of the same material or different materials.

[0078] Exemplarily, the material of the stopping segment 20 may be a combination of one or more of resin, silica gel, biodegradable material, and organic plant material.

[0079] The resin includes but is not limited to PET (polyethylene terephthalate), acetate fiber, and the like.

[0080] Biodegradable materials include, but are not limited to, polylactic acid.

[0081] According to different design requirements, the structures of the two stopper segments 20 can be the same or different. Figure 5 , Figure 6 and Fig. 9 At least one of the two stopper segments 20 may be an airway tube having a hollow passage 20a.

[0082] The airway tube can be a PET tube, an acetate tube, a silicone tube, a paper tube, etc.

[0083] The hollow passage 20a is a passage through which air flows.

[0084] See also Figure 6 The airway tube may include a tube body 21 having a hollow channel 20a and a partition 22 arranged in the hollow channel 20a, and the partition 22 divides a plurality of first airways 20a1 in the hollow channel 20a, that is, the hollow channel 20a may be further divided into a plurality of first airways 20a1, and airflow may pass through different first airways 20a1 respectively.

[0085] In some embodiments, see Figure 5 , the partition 22 may not be provided in the hollow channel 20a of the airway tube.

[0086] For example, see Figure 8 At least one of the two stop segments 20 may also have a plurality of second air passages 20b, each second air passage 20b at least passing through at least one of the two opposite ends of the stop segment 20 along the first direction.

[0087] Figure 8 The second air channel 20b in the embodiment runs through two opposite ends of the stop segment 20 along the first direction. In other embodiments, the second air channel 20b may also only run through one end of the stop segment 20 along the first direction.

[0088] For example, see Figure 3 , Figure 7 , Fig. 9 and Fig.10 At least one of the two stop segments 20 may also be a solid fiber structure or a solid porous molecular sieve structure.

[0089] The solid fiber structural member is mainly composed of fibers, and the airflow passes through the pores naturally formed between the fibers. The solid fiber structural member does not have a macroscopic airway, and the macroscopic airway refers to an airflow channel that is mainly formed by processing (such as the first airway 20a1 and the second airway 20b described in the previous embodiment). The cross-sectional area and length and other dimensions of the airway can be changed according to the design requirements, while the cross-sectional area and length and other dimensions of the pores between the fibers are mainly formed naturally during the processing.

[0090] The material of the solid fiber structural member can be PET, acetate fiber, etc.

[0091] The material of the solid porous molecular sieve structure is porous molecular sieve. Porous molecular sieve is a porous crystal with a large number of naturally formed pores. The pore sizes of the pores are relatively uniform, and these pores generally only allow molecules smaller than their pore sizes to enter. Therefore, porous molecular sieves can be used to screen molecules in substances by size.

[0092] The solid porous molecular sieve structure also does not have macroscopic air channels.

[0093] For example, see Figure 3 At least one of the two stopper sections 20 may also be a breathable paper or a breathable film (i.e. Figure 3 The first stop section 20').

[0094] See also Figure 1 and Figure 3 The aerosol generating article 100 may further be provided with an outer wrapping layer 30 , and the outer wrapping layer 30 is coated on the outer peripheral side of the aerosol generating substrate segment 10 and the two stopper segments 20 .

[0095] The material of the outer wrapping layer 30 is not limited. For example, the outer wrapping layer 30 includes but is not limited to one or more combinations of fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, PE (polyethylene), PBAT (butylene adipate-co-terephthalate) and other materials.

[0096] Aerosol generating products in related technologies are generally provided with four or more components including a matrix segment, a support segment, a cooling segment, and a filtering segment. The manufacturing process is relatively complicated, and the aerosol generating matrix segment will shrink and deform to a certain extent after being heated. During the inhalation process, the aerosol generating matrix segment is easy to loosen or even fall off.

[0097] The aerosol generating product 100 of the embodiment of the present application is provided with stopper sections 20 at the opposite ends of the aerosol generating matrix section 10 along the first direction. The aerosol generating product 100 does not have components such as a supporting section, a cooling section, and a filtering section. Its structure is simple and easy to process and manufacture. At the same time, during the heating process of the aerosol generating product 100, one stopper section 20 is located upstream of the aerosol generating matrix section 10 along the airflow direction, and the other stopper section 20 is located downstream of the aerosol generating matrix section 10 along the airflow direction. Both stopper sections 20 can stop the aerosol generating matrix section 10, thereby better preventing the aerosol generating matrix section 10 from loosening due to shrinkage and deformation after heating. The aerosol generating product 100 of the embodiment of the present application is not only easy to process and manufacture, but also can improve the suction experience.

[0098] In one embodiment, please refer to Figure 3 For ease of description, the two stop segments 20 may be respectively referred to as the first stop segment 20′ and the second stop segment 20″, the suction resistance of the first stop segment 20′ is smaller than the suction resistance of the second stop segment 20″, the end of the aerosol generating article 100 provided with the first stop segment 20′ is the air inlet end, and the end of the aerosol generating article 100 provided with the second stop segment 20″ is the air outlet end.

[0099] That is, the first stop segment 20 ′ is the stop segment 20 located upstream of the aerosol generating substrate segment 10 along the airflow direction, and the second stop segment 20 ″ is the stop segment 20 located downstream of the aerosol generating substrate segment 10 along the airflow direction.

[0100] Since the first stop segment 20' needs to allow the external airflow to smoothly enter the aerosol generating matrix segment 10 while stopping, the suction resistance of the first stop segment 20' can be relatively small, and the second stop segment 20" can be used to increase the suction resistance of the aerosol generating product 100 to prevent the occurrence of suction voids. Therefore, the suction resistance of the second stop segment 20" can be relatively large.

[0101] Exemplarily, the air permeability of the first stop segment 20' may be 6000CU to 25000CU (including endpoint values), for example, the air permeability of the first stop segment 20' may be 6000CU, 8000CU, 10000CU, 12000CU, 15000CU, 18000CU, 22000CU, 25000CU, etc.

[0102] CU is the air permeability unit cm 3 / (min·cm 2 ·kpa) abbreviation.

[0103] Preferably, the air permeability of the first stop section 20' may be 6000 CU.

[0104] Exemplarily, the dimension ratio of the second stop segment 20 ″ to the aerosol generating substrate segment 10 along the first direction may be 1:3-5. For example, the dimension ratio of the second stop segment 20 ″ to the aerosol generating substrate segment 10 along the first direction may be 1:3, 1:3.5, 1:4, or 1:5.

[0105] The dimension along the first direction refers to the distance between the two opposite ends of the component along the first direction, for example, Figure 2 The first direction in the figure is equivalent to the length direction of the aerosol generating article 100, and the dimension along the first direction actually refers to the length dimension of the component.

[0106] Taking the second stop segment 20 ″ as an example, the dimension of the second stop segment 20 ″ along the first direction refers to the distance between two opposite ends of the second stop segment 20 ″ along the first direction, which is also equivalent to the length dimension of the second stop segment 20 ″.

[0107] Preferably, the dimension of the aerosol generating article 100 along the first direction may be 12 mm to 20 mm (including the endpoint values). For example, the dimension of the aerosol generating article 100 along the first direction may be 12 mm, 14 mm, 15 mm, 17 mm, 19 mm, or 20 mm.

[0108] The dimension ratio of the second stopper segment 20 ″ to the aerosol generating substrate segment 10 along the first direction is set in the range of 1:3 to 5, which can better improve the draw resistance of the aerosol generating article 100 .

[0109] Exemplarily, the dimension of the second stop segment 20 ″ along the first direction may be 5 mm to 10 mm (including the endpoint values). For example, the dimension of the second stop segment 20 ″ along the first direction may be 5 mm, 7 mm, 7.5 mm, 8.5 mm, 9 mm, 10 mm, etc.

[0110] The dimension of the second stop section 20 ″ along the first direction is set within the range of 5 mm to 10 mm, which can not only improve the inhalation resistance of the aerosol generating product 100 , but also prevent excessive retention of aerosol in the second stop section 20 ″ to affect the inhalation experience.

[0111] See also Figure 3 The dimension of the first stopping segment 20 ′ along the first direction may be smaller than the dimension of the second stopping segment 20 ″ along the first direction, that is, the first stopping segment 20 ′ may be relatively thin to facilitate airflow.

[0112] Exemplarily, the first stop section 20' can be a breathable paper or a breathable film. Both the breathable paper and the breathable film have good air permeability, and airflow can pass through relatively smoothly.

[0113] For example, the second stopper segment 20 ″ may be a solid fiber structure, a solid porous molecular sieve structure, an airway tube, a stopper segment 20 having a second airway 20 b, etc.

[0114] In some embodiments, the dimension of the first stopping segment 20 ′ along the first direction may also be greater than or equal to the dimension of the second stopping segment 20 ″ along the first direction.

[0115] by Figure 3 Taking the aerosol generating product 100 shown as an example, when the aerosol generating matrix segment 10 is heated, the aerosol generating matrix segment 10 releases aerosol. Since at least some of the micropores or gaps in the wall material of the aerosol generating matrix segment 10 are connected to the third air channel 10a, the aerosol released by the aerosol generating matrix segment 10 when heated can enter the third air channel 10a through the micropores or gaps connected to the third air channel 10a. At the same time, external airflow such as air can enter the first stop segment 20′ from the outside of the first stop segment 20′, and then enter the third air channel 10a of the aerosol generating matrix segment 10. In this way, during the inhalation process, the airflow gathered in the third air channel 10a can carry the aerosol to the second stop segment 20″, and after being filtered and cooled by the second stop segment 20″, it enters the user's mouth.

[0116] In one embodiment, please refer to Figures 4 to 10 The aerosol generating article 100 may also be a structure in which the air inlet end and the air outlet end are interchangeable.

[0117] That is to say, any one of the two stop segments 20 can be located downstream of the aerosol generating substrate segment 10 along the airflow direction, and any one of the two stop segments 20 can also be located upstream of the aerosol generating substrate segment 10 along the airflow direction. This is equivalent to that in the process of inserting the aerosol generating product 100 into the aerosol generating device 200, there is no need to distinguish the insertion direction of the aerosol generating product 100, and any end of the aerosol generating product 100 along the first direction can be used as the insertion end of the aerosol generating device 200.

[0118] To facilitate the interchange of the air inlet end and the air outlet end, the two stopper sections 20 may be made of materials with the same or similar performance parameters.

[0119] Please continue reading Figures 4 to 10 , the sizes of the two stop segments 20 along the first direction can be equal, that is, there is no obvious difference in the sizes of the two stop segments 20 along the first direction, so as to facilitate processing and manufacturing.

[0120] In some embodiments, the sizes of the two stopping segments 20 along the first direction may be different, that is, the size of one of the stopping segments 20 along the first direction may be greater than the size of the other stopping segment 20 along the first direction.

[0121] To ensure the consistency of suction resistance, illustratively, the size ratio of each stop segment 20 to the aerosol generating matrix segment 10 along the first direction can be: 1:2~5. For example, the size ratio of the stop segment 20 to the aerosol generating matrix segment 10 along the first direction can be 1:2, 1:2.5, 1:3, 1:4, 1:5.

[0122] Exemplarily, the suction resistance of each stop segment 20 may be 200Pa to 310Pa (including endpoint values), for example, the suction resistance of each stop segment 20 may be 200Pa, 220Pa, 240Pa, 260Pa, 280Pa, 300Pa, or 310Pa.

[0123] The two stopper sections 20 may adopt the same structure. For example, the two stopper sections 20 may be Figure 5 The ones shown are all airway tubes, but they can also be Figure 7 and Fig.10 The structures shown are all solid fiber structures or solid porous molecular sieve structures. Figure 8 The stop segments 20 shown in the drawings all have a second air channel 20 b.

[0124] The two stopper sections 20 may also adopt different structures, for example, Figure 6 and Fig. 9 In the embodiment, one of the two stopper segments 20 is an airway tube, and the other stopper segment 20 is a solid fiber structure or a solid porous molecular sieve structure.

[0125] by Figure 7 Taking the aerosol generating article 100 shown in FIG. 1 as an example, when both stopper sections 20 are solid fiber structural members, the aerosol generating article 100 can be placed in Fig.11 In the aerosol generating device 200 shown, the aerosol generating matrix segment 10 is heated by the heating component 220, and the user inhales through the filter 230. Alternatively, the aerosol generating product 100 can also be placed in other aerosol generating devices that are not provided with a filter, and the user can directly inhale any one of the stop segments 20, which is equivalent to the stop segment 20 being used as a filter segment.

[0126] In some embodiments, the two stopper segments 20 may also be one of breathable paper and breathable film.

[0127] In one embodiment, please refer to Fig.10 At least one of the two stop segments 20 may also be spaced apart from the aerosol generating substrate segment 10 so that a cavity 20c is formed at the spaced apart location.

[0128] That is, there may be only one stopper section 20 spaced apart from the aerosol generating substrate section 10, or Fig.10Both stop segments 20 are shown to be spaced apart from the aerosol-generating substrate segment 10 .

[0129] The cavity 20c can reduce the interception effect of the airflow in the stop section 20, thereby improving the delivery efficiency of the aerosol.

[0130] Exemplarily, the dimension ratio of the cavity 20c and the stop segment 20 forming the cavity 20c along the first direction may be 1:5-10. For example, the dimension ratio of the cavity 20c and the stop segment 20 forming the cavity 20c along the first direction may be 1:5, 1:6, 1:7.5, 1:8, 1:9, 1:10.

[0131] by Figure 5 Taking the aerosol generating product 100 shown as an example, when the aerosol generating matrix segment 10 is heated, the aerosol generating matrix segment 10 releases the aerosol. Since at least some of the micropores or gaps in the wall material of the aerosol generating matrix segment 10 are connected to the third air channel 10a, the aerosol released by the aerosol generating matrix segment 10 when heated can enter the third air channel 10a through the micropores or gaps connected to the third air channel 10a. At the same time, external airflow such as air can enter the stop segment 20 from the outside of one of the stop segments 20, and then enter the third air channel 10a of the aerosol generating matrix segment 10. In this way, during the inhalation process, the airflow gathered in the third air channel 10a can carry the aerosol to the other stop segment 20, and after being filtered and cooled by the stop segment 20, it enters the user's mouth.
