Detailed Description

In describing embodiments of the present application, it should be noted that the azimuth or positional relationship indicated by the term "first direction" or the like is based on the azimuth or positional relationship shown in fig. 2, and these azimuth terms are merely for convenience in describing embodiments of the present application and simplifying the description, and do not indicate or imply that the apparatus or element to be referred to must have a specific azimuth, be configured and operated in a specific azimuth, and thus should not be construed as limiting the embodiments of the present application.

An embodiment of the present application provides an aerosol-generating article 100, see fig. 1 to 10, the aerosol-generating article 100 comprising an aerosol-generating substrate segment 10 and two stop segments 20, the two stop segments 20 being arranged at opposite ends of the aerosol-generating substrate segment 10 in a first direction, respectively.

Referring to fig. 11, the aerosol-generating article 100 is for use with an aerosol-generating device 200 having a heating assembly 220, in particular, the heating assembly 220 heat-atomizes an aerosol-generating substrate segment 10 in the aerosol-generating article 100 to produce an aerosol for inhalation by a user or for use in medicine, cosmesis, etc.

There are various heating modes of the heating member 220, and exemplary heating modes include center heating and circle heating, wherein the center heating mode refers to that the heating member 220 is inserted into the aerosol-generating article 100 to bake the aerosol-generating article 100 from inside to outside. The circumferential heating means that the heating member 220 is disposed at the periphery of the aerosol-generating article 100 to perform baking heating of the aerosol-generating article 100 from outside to inside. The heating modes can be specifically resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating and the like.

The aerosol-generating article 100 may not be provided with a filter segment for contact with the mouth of a user, and for example, referring to fig. 11, the aerosol-generating device 200 may be provided with a filter 230 and a housing 210 having a suction channel 210a, the filter 230 being in communication with the suction channel 210a, and during the suction of a user, aerosols generated by the heated aerosol-generating substrate segment 10 entering the mouth of the user through the suction channel 210a and the filter 230.

The particular structure of the aerosol-generating substrate segment 10 is not limited herein, and in an exemplary embodiment, the aerosol-generating substrate segment 10 may be made from the aerosolization medium itself, such as from a fumigant flavor medium. In other embodiments, the aerosol-generating substrate segment 10 may also comprise a substrate, such as carbon fibers, which may be high temperature resistant, and an atomizing medium disposed on the substrate, such that the strength of the aerosol-generating substrate segment 10 may be increased and the aerosol-generating substrate segment may be subjected to a degree of high temperature without generating an odor.

The specific composition of the aerosol-generating substrate segment 10 is not limited herein, and in an exemplary embodiment, the aerosol-generating substrate segment 10 may comprise a plant component, an adjunct component, a smoke agent component, an adhesive component, and the like.

In one embodiment, the plant component is one or more of tobacco leaf raw material, tobacco leaf fragments, tobacco stems, tobacco powder, and powder formed by crushing fragrant plants. The plant components are core sources of product fragrance, endogenous substances in the plant components, such as nicotine, enter human blood through atomization, and the pituitary gland is promoted to produce dopamine, so that physiological satisfaction is obtained.

In one embodiment, the auxiliary component may be one or more of an inorganic filler, a lubricant, and an emulsifier. Wherein the inorganic filler comprises one or more of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talcum powder and diatomite. The inorganic filler can provide skeleton supporting function for plant components, and has micropores, so that the porosity of the wall material formed by the plant components can be improved, and the release rate of aerosol is improved.

The lubricant comprises one or more 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 force among the particles, ensure that the overall density of the particle distribution is more uniform, reduce the pressure required by the molding of the die and reduce the abrasion of the die.

The emulsifier comprises one or more of polyglycerol fatty acid ester, tween-80 and polyvinyl alcohol. The emulsifier can slow down the loss of the fragrant substances in the storage process to a certain extent, increase the stability of the fragrant substances and improve the sensory quality of the product. Emulsifiers (also known as surfactants) reduce the interfacial tension of water-soluble and water-insoluble components in the mixed system and form stronger films on the surface of the droplets or double layers on the surface of the droplets due to the charge given by the emulsifier, preventing the droplets from aggregating with each other while maintaining a uniform emulsion. The consistency of product quality can be improved by emulsifying and homogenizing the two immiscible components.

The function of the smoke agent component is to generate a significant amount of steam upon heating, thereby enhancing the smoke content of the smoking article. In one embodiment, the smoking agent may include, for example, one or more of a monohydric alcohol (e.g., menthol), a polyhydric alcohol (e.g., propylene glycol, triethylene glycol, 1, 3-butanediol, and glycerol), an ester of a polyhydric alcohol (e.g., glyceryl monoacetate, glyceryl diacetate, or glyceryl triacetate), a monocarboxylic acid, a polycarboxylic acid (e.g., lauric acid, myristic acid), or an aliphatic ester of a polycarboxylic acid (e.g., dimethyl dodecanedioate, dimethyl tetradecanedioate, erythritol, 1, 3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, termitidine (Triactin), meso-erythritol, glyceryl diacetate mixtures, diethyl suberate, triethyl citrate, benzyl benzoate, benzyl phenylacetate, ethyl vanillic acid, tributyrin, lauryl acetate).

In one embodiment, the binder component is a natural plant extract, a non-ionized modified viscous polysaccharide, including one or more of tamarind polysaccharide, pullulan polysaccharide, algal polysaccharide, locust bean gum, guar gum, xyloglucan. The adhesive is in close contact with the interface of the component materials of the product by wetting, and generates intermolecular attraction force, thereby playing a role of bonding the powder, liquid and the like of the component materials. And meanwhile, natural plant extraction and nonionic adhesive are selected, so that the release of harmful substances such as methanol, formaldehyde and acrolein caused by colloid modification can be avoided, and the safety of the product is improved.

Illustratively, the aerosol-generating substrate segment 10 may be a particulate combination, which is a reconstituted tobacco medium, such as a reconstituted tobacco medium containing components of a smoking agent, tobacco or the like. The aerosol-generating substrate segments 10 may be of unitary construction, such as one of injection molded construction, compression molded construction, extrusion molded construction, cast molded construction, compression molded construction, and 3D printed molded construction. Extrusion molding refers to a processing method in which a raw material mixture is added into an extruder, and the raw material is pushed forward by a screw through the action between a barrel of the extruder and the screw, and continuously passes through a machine head to be manufactured into various section products or semi-products. The aerosol matrix formed by extrusion molding is in a strip shape.

Because the aerosol-generating substrate segment 10 is a particle combination, the aerosol-generating substrate segment 10 is an integral medium after being heated, sucked or stopped being heated, the phenomenon of disintegration and dropping is not easy to occur, and the problems that the flake-shaped, filament-shaped or scattered particle aerosol-generating substrate segment 10 in the prior art is loose, filament-shaped components, particle components fall off and is not easy to clean are solved.

In addition, the shape of the aerosol-generating substrate segment 10 is not limited, and referring to fig. 3, for example, the aerosol-generating substrate segment 10 may be cylindrical, and the cross-section of the cylindrical aerosol-generating substrate segment 10 may be circular, or may be other shapes, such as polygonal (including but not limited to triangular, square, prismatic, etc.), elliptical, racetrack, or irregular, wherein irregular refers to other symmetrical or asymmetrical shapes other than those listed above.

Referring to fig. 3, 5-10, the aerosol-generating substrate segment 10 may be an integrally formed structure having at least one third air passage 10a therein, the third air passage 10a extending through at least one of the opposite ends of the aerosol-generating substrate segment 10 in the first direction.

The third air passage 10a in fig. 3, 5-10 extends through opposite ends of the aerosol-generating substrate segment 10 in the first direction, and in some embodiments the third air passage 10a may extend through only one end of the aerosol-generating substrate segment 10 in the first direction, while the other end is a closed end.

The penetration of the third air passage 10a through both ends of the aerosol-generating substrate segment 10 in the first direction is more advantageous for reducing the resistance to inhalation by the user than the penetration of the third air passage 10a through one end of the aerosol-generating substrate segment 10 in the first direction.

The number of the third air passages 10a may be one or a plurality.

The third air passage 10a may be a straight air passage as shown in fig. 3, 5 to 10, and the straight air passage is an air passage extending along a straight line, or the extending direction of the straight air passage is a straight line.

The third air passage 10a may be a spiral air passage, and the spiral air passage is a curved air passage with curvature other than 0 along at least a part of the extending direction, for example, the spiral air passage may have a structure with a curved section with curvature other than 0 and a straight section with curvature other than 0, or may have a structure with a curved section with curvature other than 0 and a straight section without curvature other than 0 along the extending direction of the spiral air passage. That is, the spiral air passage may extend from the start point to the end point of the spiral air passage in the extending direction, as long as the spiral air passage does not extend in a straight line.

When the number of the third air passages 10a is plural, it is possible that a part of the third air passages 10a is a straight air passage and another part of the third air passages 10a is a spiral air passage.

The shape of the cross section of the third air passage 10a is not limited, and for example, the shape of the cross section may be circular, polygonal (including but not limited to triangle, square, prism, etc.), elliptical, racetrack, or irregular, etc.

The third air passage 10a can prolong the air flow path, and improve the flow speed of the air flow in the aerosol-generating substrate segment 10, so that the impact force of the air flow can be improved, the aerosol can be uniformly mixed, the extraction efficiency and uniformity of the aerosol in the aerosol-generating substrate segment 10 can be improved, and the suction feeling of a user can be improved.

The first direction is the direction of alignment of the two stop segments 20 and the aerosol-generating substrate segments 10, the aerosol-generating article 100 is inserted into the aerosol-generating device 200 in the first direction, the aerosol-generating article 100 is also removed from the aerosol-generating device 200 in the first direction, and the length of the aerosol-generating substrate segments 10 in the first direction may be longer, shorter, or the same as the length in the other directions.

For example, when the outer contour of the aerosol-generating substrate segment 10 is cylindrical, the first direction is the axial direction of the aerosol-generating substrate segment 10, it is noted that the axial length of the aerosol-generating substrate segment 10 may be smaller than its diameter.

For another example, when the outer contour of the aerosol-generating substrate segment 10 is rectangular parallelepiped, the first direction may still be the direction defined above, i.e. the direction in which the two stop segments 20 and the aerosol-generating substrate segment 10 are arranged, or the direction in which the aerosol-generating article 100 is taken on the aerosol-generating device 200, the first direction of the aerosol-generating substrate segment 10 may be any one of the length, width, height of the rectangular parallelepiped.

For example, referring to fig. 2 and 4, the aerosol-generating substrate segment 10 and the two stop segments 20 may be cylindrical bodies having a uniform outer diameter and coaxially arranged, the first direction being the axial direction of the aerosol-generating substrate segment 10 and the two stop segments 20.

With continued reference to fig. 2-10, both stopper segments 20 may be traversed by the air flow, in particular, during heating of the aerosol-generating substrate segments 10, the ambient air flow passes through one of the stopper segments 20 into the aerosol-generating substrate segments 10 and then carries the aerosol generated by the aerosol-generating substrate segments 10 through the other stopper segment 20 to flow outside the aerosol-generating article 100. The airflow and aerosol exiting the aerosol-generating article 100 passes through the filter 230 into the user's mouth.

That is, one of the two stopper segments 20 is located upstream of the aerosol-generating substrate segment 10 in the direction of airflow, and the other stopper segment 20 is located downstream of the aerosol-generating substrate segment 10 in the direction of airflow. Since the aerosol-generating substrate segment 10 will have a certain shrinkage deformation during heating, the upstream stop segment 20 may mainly block the aerosol-generating substrate segment 10 to prevent the shrinkage deformed aerosol-generating substrate segment 10 from loosening and falling off, while the downstream stop segment 20 may better prevent the aerosol-generating substrate segment 10 from moving or slipping off during pumping, i.e. both stop segments 20 may act as stops.

In addition, the downstream stop segment 20 can provide a certain suction resistance, so as to better prevent the aerosol-generating article 100 from influencing the suction experience due to the suction cavity caused by too small suction resistance, and in addition, the downstream stop segment 20 can also play a certain role in cooling the aerosol.

It should be noted that the aerosol-generating article 100 relies on the aerosol-generating substrate segment 10 to generate an aerosol, and the stopper segment 20 does not generate an aerosol.

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

Illustratively, the material of the stop segment 20 may be a combination of one or more of a resin, a silicone, a biodegradable material, an organic plant material.

Resins include, but are not limited to, PET (polyethylene terephthalate ), acetate, and the like.

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

The two stop segments 20 may be identical or different in construction, depending on the design requirements. For example, referring to fig. 5, 6 and 9, at least one of the two stop segments 20 may be an airway tube having a hollow passage 20 a.

The airway tube may be a PET tube, acetate tube, silicone tube, paper tube, or the like.

The hollow passage 20a is a passage through which the air flow passes.

Referring to fig. 6, the air duct may include a duct body 21 having a hollow passage 20a and a partition 22 disposed in the hollow passage 20a, wherein the partition 22 divides the hollow passage 20a into a plurality of first air passages 20a1, that is, the hollow passage 20a may further divide the hollow passage 20a into a plurality of first air passages 20a1, and the air flows may pass through the different first air passages 20a1, respectively.

In some embodiments, referring to fig. 5, the separator 22 may not be disposed in the hollow passage 20a of the airway tube.

For example, referring to fig. 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 extending through at least one of the opposite ends of the stop segment 20 in the first direction.

The second air passage 20b in fig. 8 extends through opposite ends of the stop segment 20 in the first direction, and in other embodiments, the second air passage 20b may extend through only one of the ends of the stop segment 20 in the first direction.

For example, referring to fig. 3, 7, 9 and 10, at least one of the two stop segments 20 may also be a solid fibrous structure or a solid porous molecular sieve structure.

The solid fibrous structure is composed primarily of fibers, with air flow passing through naturally occurring voids between the fibers. The solid fiber structure is not provided with macroscopic air passages, the macroscopic air passages are air passages which are mainly formed by processing (such as the first air passage 20a1 and the second air passage 20b in the previous embodiment), the cross sectional area, the length and the like of the air passages can be changed according to design requirements, and the cross sectional area, the length and the like of pores among fibers are mainly formed naturally in the processing process.

The material of the solid fiber structure can be PET, acetate fiber and the like.

The material of the solid porous molecular sieve structural member is porous molecular sieve, the porous molecular sieve is a porous crystal, the porous molecular sieve is provided with a plurality of naturally formed pore passages, the pore diameters of the pore passages are relatively uniform, and the pore passages generally only allow molecules with smaller size than the pore diameters to enter, so the porous molecular sieve can be used for sieving molecules in substances according to the size.

Solid porous molecular sieve structures also do not provide macroscopic airways.

For example, referring to fig. 3, at least one of the two stop segments 20 may also be a gas permeable paper or film (i.e., the first stop segment 20' in fig. 3).

Referring to fig. 1 and 3, the aerosol-generating article 100 may further be provided with an outer wrapper 30, the outer wrapper 30 wrapping around the outer peripheral sides of the aerosol-generating substrate segment 10 and the two stopper segments 20.

The material of the outer wrapping layer 30 is not limited, and for example, the outer wrapping layer 30 includes, but is not limited to, one or more of fiber paper, metal foil composite fiber paper, polyethylene composite fiber paper, PE (polyethylene), PBAT (butyleneadipate-co-terephthalate, polybutylene terephthalate-adipate) and the like.

The aerosol-generating product in the related art is generally provided with up to four or more sections such as a substrate section, a supporting section, a cooling section, a filtering section and the like, the manufacturing process is more complex, and the aerosol-generating substrate section has a certain shrinkage deformation after being heated, and is easy to loosen and even fall off in the suction process.

In the aerosol-generating article 100 according to the embodiment of the present application, the stop sections 20 are respectively disposed at two opposite ends of the aerosol-generating substrate section 10 along the first direction, and the aerosol-generating article 100 has no support section, cooling section, filtering section, etc., and has a simple structure, and is convenient for processing and manufacturing. Meanwhile, during the heating process of the aerosol-generating article 100, one stop section 20 is located upstream of the aerosol-generating substrate section 10 in the airflow direction, the other stop section 20 is located downstream of the aerosol-generating substrate section 10 in the airflow direction, and both stop sections 20 can play a role in stopping the aerosol-generating substrate section 10, so that loosening of the aerosol-generating substrate section 10 due to shrinkage deformation after heating can be well prevented. The aerosol-generating article 100 of the embodiments of the present application is both convenient to manufacture and can enhance the feel of the smoking experience.

In an embodiment, referring to fig. 3, for convenience of description, the two stop segments 20 may be respectively referred to as a first stop segment 20' and a second stop segment 20″, where the suction resistance of the first stop segment 20' is smaller than that of the second stop segment 20″ and the end of the aerosol-generating article 100 provided with the first stop segment 20' is an air inlet end and the end of the aerosol-generating article 100 provided with the second stop segment 20″ is an air outlet end.

That is, the first stop segment 20' is a stop segment 20 located upstream of the aerosol-generating substrate segment 10 in the airflow direction, and the second stop segment 20″ is a stop segment 20 located downstream of the aerosol-generating substrate segment 10 in the airflow direction.

Since the first stopper segment 20 'is stopped while also requiring smooth flow of external air into the aerosol-generating substrate segment 10, the suction resistance of the first stopper segment 20' may be relatively small, while the second stopper segment 20″ may be used to increase the suction resistance of the aerosol-generating article 100 to prevent suction voids from occurring, and thus the suction resistance of the second stopper segment 20″ may be relatively large.

Illustratively, the air permeability of the first stop segment 20 'may be 6000 CU-25000 CU (including end point values), for example, the air permeability of the first stop segment 20' may be 6000CU, 8000CU, 10000CU, 12000CU, 15000CU, 18000CU, 22000CU, 25000CU, and the like.

CU is an abbreviation for air permeability unit cm ³/(min·cm². Kpa).

More preferably, the first stop segment 20' may have a permeability of 6000CU.

Illustratively, the second stop segment 20″ to the aerosol-generating substrate segment 10 may have a dimension ratio in the first direction of 1:3-5, e.g., the second stop segment 20″ to the aerosol-generating substrate segment 10 may have a dimension ratio in the first direction of 1:3, 1:3.5, 1:4, 1:5.

The dimension in the first direction refers to the distance between opposite ends of the member in the first direction, e.g. the first direction in fig. 2 corresponds to the length direction of the aerosol-generating article 100, the dimension in the first direction actually referring to the length dimension of the member.

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, and is also equivalent to the length dimension of the second stop segment 20'.

More preferably, the aerosol-generating article 100 may have a dimension in the first direction of 12mm to 20mm (inclusive), e.g. the aerosol-generating article 100 may have a dimension in the first direction of 12mm, 14mm, 15mm, 17mm, 19mm, 20mm.

The dimension ratio of the second stop section 20″ to the aerosol-generating substrate section 10 in the first direction is set in the range of 1:3-5, which can better improve the resistance to absorption of the aerosol-generating article 100.

Illustratively, the second stop segment 20″ may have a dimension in the first direction of 5 mm-10 mm (inclusive), e.g., the second stop segment 20″ may have a dimension in the first direction of 5mm, 7mm, 7.5mm, 8.5mm, 9mm, 10mm, etc.

The dimension of the second stop section 20 'along the first direction is set in the range of 5 mm-10 mm, so that not only can the suction resistance of the aerosol-generating article 100 be improved, but also the suction experience can be prevented from being influenced due to excessive interception of the aerosol in the second stop section 20'.

Referring to fig. 3, the dimension of the first stop segment 20 'in the first direction may be smaller than the dimension of the second stop segment 20″ in the first direction, that is, the first stop segment 20' may be relatively thin to facilitate the passage of air flow.

Illustratively, the first stop segment 20' may be a gas permeable paper or a gas permeable membrane, both of which have good gas permeability and through which the gas flow can pass relatively smoothly.

Illustratively, the second stop segment 20″ may be a solid fibrous structure, a solid porous molecular sieve structure, an air channel tube, a stop segment 20 having a second air channel 20b, or the like.

In some embodiments, the dimension of the first stop segment 20' in the first direction may also be greater than or equal to the dimension of the second stop segment 20″ in the first direction.

Taking the aerosol-generating article 100 shown in fig. 3 as an example, when the aerosol-generating substrate segment 10 is heated, the aerosol-generating substrate segment 10 releases the aerosol, and since at least some of the micropores or gaps in the wall material of the aerosol-generating substrate segment 10 are connected to the third air channel 10a, the aerosol released by heating the aerosol-generating substrate segment 10 can enter the third air channel 10a through the micropores or gaps connected to the third air channel 10a, and at the same time, an 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 substrate segment 10, so that during the sucking process, the air flow collected 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″ enters the oral cavity of the user.

In one embodiment, referring to fig. 4-10, the aerosol-generating article 100 may also be of interchangeable construction with the inlet and outlet ends.

That is, either one of the two stop segments 20 may be located downstream of the aerosol-generating substrate segment 10 in the airflow direction, either one of the two stop segments 20 may also be located upstream of the aerosol-generating substrate segment 10 in the airflow direction, corresponding to the fact that during insertion of the aerosol-generating article 100 into the aerosol-generating device 200, no distinction is required with respect to the direction of insertion of the aerosol-generating article 100, either end of the aerosol-generating article 100 in the first direction may be used as the insertion end for insertion into the aerosol-generating device 200.

To facilitate the exchange of the inlet and outlet ends, the two stop segments 20 may be made of materials having the same or similar performance parameters.

With continued reference to fig. 4-10, the dimensions of the two stop segments 20 along the first direction may be equal, i.e., there may be no significant difference in the dimensions of the two stop segments 20 along the first direction, for ease of manufacturing.

In some embodiments, the dimensions of the two stop segments 20 in the first direction may also be different, that is, the dimension of one stop segment 20 in the first direction may also be greater than the dimension of the other stop segment 20 in the first direction.

To ensure uniformity of the draw resistance, for example, the size ratio of each stop segment 20 to the aerosol-generating substrate segment 10 in the first direction may be 1:2-5, e.g., the size ratio of the stop segment 20 to the aerosol-generating substrate segment 10 in the first direction may be 1:2, 1:2.5, 1:3, 1:4, 1:5.

Illustratively, the suction resistance of each stop segment 20 may be 200Pa to 310Pa (including end point values), for example, the suction resistance of each stop segment 20 may be 200Pa, 220Pa, 240Pa, 260Pa, 280Pa, 300Pa, 310Pa.

The two stop segments 20 may have identical structures, for example, the two stop segments 20 may be airway tubes as shown in fig. 5, solid fiber structural members or solid porous molecular sieve structural members as shown in fig. 7 and 10, and stop segments 20 having second airways 20b as shown in fig. 8.

The two stop segments 20 may also be configured differently, for example, in fig. 6 and 9, one stop segment 20 of the two stop segments 20 is an airway tube and the other stop segment 20 is a solid fiber structure or a solid porous molecular sieve structure.

Taking the aerosol-generating article 100 shown in fig. 7 as an example, when both stopper segments 20 are solid fibrous structures, the aerosol-generating article 100 may be placed in the aerosol-generating device 200 shown in fig. 11, the aerosol-generating substrate segment 10 may be heated by the heating assembly 220, the user may draw through the filter 230, or the aerosol-generating article 100 may be placed in other aerosol-generating devices without filters, and the user may directly draw on any one of the stopper segments 20, which corresponds to the stopper segment 20 being used as a filter segment.

In some embodiments, the two stop segments 20 may also be one of a gas permeable paper and a gas permeable film.

In one embodiment, referring to fig. 10, at least one of the two stop segments 20 may also be spaced apart from the aerosol-generating substrate segment 10 such that a cavity 20c is formed at the spacing.

That is, only one stopper segment 20 may be provided spaced apart from the aerosol-generating substrate segment 10, or both stopper segments 20 may be provided spaced apart from the aerosol-generating substrate segment 10 as shown in fig. 10.

The cavity 20c may reduce the trapping effect of the airflow at the stopper section 20, which may further enhance the delivery efficiency of the aerosol.

For example, the ratio of the dimensions of the cavity 20c to the dimension of the stop segment 20 forming the cavity 20c along the first direction may be 1:5-10, for example, the ratio of the dimensions of the cavity 20c to the dimension of 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.

Taking the aerosol-generating article 100 shown in fig. 5 as an example, when the aerosol-generating substrate segment 10 is heated, the aerosol-generating substrate segment 10 releases the aerosol, and since at least some of the micropores or gaps in the wall material of the aerosol-generating substrate segment 10 are connected to the third air channel 10a, the aerosol released by heating the aerosol-generating substrate segment 10 can enter the third air channel 10a through the micropores or gaps connected to the third air channel 10a, and at the same time, an external air flow, such as air, can enter one of the stop segments 20 from the outside of the stop segment 20 and then enter the third air channel 10a of the aerosol-generating substrate segment 10, so that during the sucking process, the air flow collected in the third air channel 10a can flow to the other stop segment 20, and after being filtered and cooled by the stop segment 20, enter the oral cavity of the user.
