[0050] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] The present application embodiment provides an aerosol generating product 1, see Figures 1 to 14 , including a medium section 11, a filtering section 12, a supporting section 13, a cooling section 14 and a stopper 15.

[0052] An embodiment of the present application provides an aerosol generating system, including an aerosol generating device and an aerosol generating product 1 of any embodiment of the present application, the aerosol generating product 1 can be plugged in and out of the aerosol generating device, the aerosol generating device includes a heating element, the heating element is used to heat the medium segment 11 to generate an aerosol, and the aerosol can be discharged from the aerosol generating device for inhalation by a user.

[0053] The medium segment 11 is used to generate aerosol, that is, at least a part of the medium segment 11 is composed of an aerosol-generating substrate, so that the medium segment 11 can be used to generate aerosol for use by a user.

[0054] The specific form of the heating element is not limited, and it can be a resistive heating film, an electromagnetic induction heating element, an infrared heating coating, a laser heating element, etc., and is not limited here.

[0055] The medium segment 11 is an integral structure, that is, the medium segment 11 is integrally formed, for example, integrally extruded, integrally injected, integrally die-casted, etc.

[0056] The medium segment 11 has a first end 11a and a second end 11b opposite to each other along the length direction. The filter segment 12 is arranged near the second end 11b of the medium segment 11 . The support segment 13 and the cooling segment 14 are arranged between the filter segment 12 and the medium segment 11 .

[0057] It is understandable that the air in the external environment needs to pass through the medium segment 11 to entrain the generated aerosol. In this embodiment, the air in the external environment can entrain the aerosol through the second end 11b of the medium segment 11, the support segment 13, and the cooling segment 14 to flow to the filter segment 12 to be used by the user. The filter segment 12 can absorb large particle droplets or other impurities generated by atomization, so that the user experience is better.

[0058] The specific manner in which the air in the external environment passes through the medium segment 11 is not limited.

[0059] For example, in some embodiments, see Figure 2 and Fig.12 The air inlet end of the medium segment 11 is the first end 11a of the medium segment 11, and the air outlet end of the medium segment 11 is the second end 11b of the medium segment 11. In this way, air in the external environment can enter from the first end 11a of the medium segment 11, carry aerosol through the second end 11b of the medium segment 11, the support segment 13, the cooling segment 14, and the filter segment 12, and be inhaled by the user.

[0060] It can be understood that the air inlet end of the medium segment 11 is the end of the medium segment 11 close to the upstream of the airflow direction, and the air outlet end of the medium segment 11 is the end of the medium segment 11 close to the downstream of the airflow direction.

[0061] In other embodiments, the medium segment 11 is provided with multiple air inlets and multiple air outlets, and the multiple air inlets are all located on one side thereof perpendicular to the length direction, and the multiple air outlets are arranged at the second end 11b of the medium segment 11. In this way, air in the external environment can enter the medium segment 11 from the multiple air inlets, and be entrained with aerosol to be inhaled by the user through the second end 11b of the medium segment 11, the support segment 13, the cooling segment 14, and the filtering segment 12.

[0062] In some other embodiments, the air inlet and outlet ends of the medium segment 11 are both arranged at the second end 11b of the medium segment 11, that is, the air in the external environment can enter the medium segment 11 through the second end 11b of the medium segment 11 to entrain the aerosol, and then be inhaled by the user from the second end 11b of the medium segment 11 through the support segment 13, the cooling segment 14, and the filtering segment 12.

[0063] It should be noted that in the embodiments of the present application, the length direction does not specifically refer to the direction in which the outer contour of the medium segment 11 is the longest. The arrangement direction of the filter segment 12, the support segment 13, the cooling segment 14, and the stopper 15 is consistent with the length direction; the direction in which the aerosol generating product 1 is inserted into the aerosol generating device and the direction in which the aerosol generating product 1 is taken out of the aerosol generating device are both parallel to the length direction. The dimension of the medium segment 11 along the length direction may be longer, shorter, or the same as the dimension along other directions.

[0064] For example, in some examples, when the appearance of the medium segment 11 is cylindrical, the length direction is the axial direction of the medium segment 11. It should be noted that even if the axial dimension of the medium segment 11 is smaller than its diameter, the length direction of the medium segment 11 is still the axial direction.

[0065] In other examples, when the outer contour of the medium segment 11 is a rectangular parallelepiped, the length direction is still the direction defined above, that is, the arrangement direction of the filter segment 12, the support segment 13, the cooling segment 14, and the stopper 15; or, in the direction of taking and placing the aerosol generating product 1, the length direction of the medium segment 11 can be any direction of the length, width, and height of the rectangular parallelepiped.

[0066] The support section 13 and the cooling section 14 may be arranged at any position.

[0067] For some examples, see Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 , Fig.12 and Fig.13 The support section 13 is arranged between the cooling section 14 and the medium section 11. That is to say, the aerosol generated by the medium section flows out through the support section 13, the cooling section 14 and the filtering section 12 in sequence for the user to inhale. The support section 13 can connect and support the medium section 11 and the cooling section 14 at both ends. The cooling section 14 is used to reduce the temperature of the aerosol so that the temperature of the aerosol flowing out of the filtering section 12 is appropriate and can be better used by the user.

[0068] For other examples, see Fig.14 The cooling section 14 is arranged between the supporting section 13 and the medium section 11, that is, the aerosol flows out through the cooling section 14, the supporting section 13, and the filtering section 12 in sequence for the user to inhale. The supporting section 13 can connect and support the cooling section 14 and the filtering section 12 at both ends. The cooling section 14 is used to reduce the temperature of the aerosol so that the temperature of the aerosol flowing out of the filtering section 12 is appropriate and can be better used by the user.

[0069] The stopper 15 is used to stop and cooperate with the first end 11a of the medium segment 11. That is, the stopper 15 can abut against the first end 11a of the medium segment 11 to inhibit the medium segment 11 from moving in a direction away from the filter segment 12. For details, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 , Fig.12 and Fig.13 When the support section 13 is disposed between the cooling section 14 and the medium section 11, the stopper 15 can limit the medium section 11 in the space between the support section 13 and the stopper 15, so that the medium section 11 will not fall; see Fig.14When the cooling section 14 is disposed between the supporting section 13 and the medium section 11, the stopper 15 can confine the medium section 11 in the space between the cooling section 14 and the stopper 15, so that the medium section 11 will not fall.

[0070] It is understandable that the stopper 15 can be connected to the supporting section 13 or the cooling section 14 to obtain force support, thereby achieving stopper cooperation with the first end 11 a of the medium section 11 .

[0071] It is understandable that the stopper 15 and the medium segment 11 are not limited to the aforementioned stopper. In other embodiments, the stopper 15 may also form a stopper with the side surface of the medium segment 11 .

[0072] It should be noted that the stop cooperation between the stop member 15 and the first end 11a of the medium segment 11 can be that the medium segment 11 and the stop member 15 are spaced apart, and after the medium segment 11 moves a certain distance in the direction away from the filter segment 12, the stop member 15 abuts against the first end 11a of the medium segment 11; or, the stop member 15 and the first end 11a of the medium segment 11 always maintain an abutting state.

[0073] It is understood that in some examples, the air in the external environment can also enter the medium segment 11 from the stopper 15, that is, the stopper 15 is a structure that allows airflow to pass through, and the air in the external environment can directly pass through the stopper 15 and enter the medium segment 11, for example, see Fig.12 The air in the external environment can pass through the stopper 15 and enter the medium segment 11 through the first end 11a of the medium segment 11, and the aerosol generated by atomization can enter the filter segment 12 from the second end 11b of the medium segment 11 through the support segment 13 and the cooling segment 14.

[0074] Therefore, in the aerosol generating product 1 provided in the embodiment of the present application, the medium segment 11 cooperates with the stopper 15 to confine the medium segment 11 in the space between the support segment 13 and the stopper 15 or in the space between the cooling segment 14 and the stopper 15, so that the position of the medium segment 11 is relatively stable, and the probability of the medium segment 11 falling under gravity factors due to heat shrinkage deformation and the like is reduced, and the probability of the medium segment 11 falling out due to the shaking of the aerosol generating product 1 during transportation and use is also reduced, thereby improving the structural stability of the aerosol generating product 1; in addition, the stopper 15 can also adjust the suction resistance, and reduce the probability of the condensate generated after the aerosol condenses flowing out of the aerosol generating product 1, thereby increasing the user experience. The aerosol generated after the medium section 11 is atomized is cooled by the cooling section 14, so that the use temperature of the aerosol is suitable. The filtering section 12 filters the impurities contained in the aerosol to increase the use experience. The supporting section 13 connects the structures at both ends of the support. The structural arrangement of the aerosol generating product 1 is more reasonable and reliable. In this way, the overall reliability of the aerosol generating product 1 is high.

[0075] For some examples, see Figures 1 to 14 The aerosol generating article 1 further comprises a wrapping layer 10 , which wraps around at least a portion of the stopper 15 , the medium segment 11 , the support segment 13 , the cooling segment 14 and the circumferential outer surface of at least a portion of the filter segment 12 .

[0076] Specifically, during the manufacturing process, the wrapping layer 10 can be directly wrapped on the circumferential outer surface of at least a portion of the stopper 15, the medium segment 11, the support segment 13, the cooling segment 14, and at least a portion of the filter segment 12 through a rolling process to integrate the medium segment 11, the filter segment 12, the support segment 13, the cooling segment 14, and the stopper 15 together, thereby improving the overall structural strength of the aerosol generating product 1, reducing the probability of failure caused by separation of the various parts of the aerosol generating product 1 during transportation and use, and increasing the reliability of the aerosol generating product 1.

[0077] It is understandable that the wrapping layer 10 has a certain structural strength to reduce the probability of deformation of the aerosol generating product 1 due to airflow pressure during use. The wrapping layer 10 can be an integrated structure or a combined structure.

[0078] The specific material of the wrapping layer 10 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.

[0079] It should be noted that, when the wrapping layer 10 wraps the entire circumferential outer surface of the filter segment 12, the user can directly hold the wrapping layer 10 in the mouth to use the aerosol; when the wrapping layer 10 wraps part of the circumferential outer surface of the filter segment 12, the user can directly hold the filter segment 12 exposed outside the wrapping layer 10 in the mouth to inhale the aerosol. Of course, the user can also install a suction nozzle on the outer surface of the filter segment 12 and inhale the aerosol through the suction nozzle.

[0080] It is understandable that the cooperation mode between the stopper 15 and the wrapping layer 10 is not limited. For example, in some embodiments, the stopper 15 can be cooperated with the wrapping layer 10 by interference fit; in other embodiments, the stopper 15 can also be cooperated with the wrapping layer 10 by bonding, clamping, etc., so that the stopper 15 can be well fixed on the wrapping layer 10, and the wrapping layer 10 can provide force support for the stopper 15, which is convenient for the stopper 15 to cooperate with the medium segment 11. Of course, there can also be a gap between the wrapping layer 10 and the stopper 15, and the air in the external environment can pass through the gap between the wrapping layer 10 and the stopper 15 and enter the medium segment 11.

[0081] It is understandable that there is a certain force between the medium segment 11 and the wrapping layer 10 to suppress the tendency of the medium segment 11 to move. For example, the outer circumferential surface of the medium segment 11 is in contact with the wrapping layer 10, and the position of the medium segment 11 is fixed by the friction between the outer circumferential surface of the medium segment 11 and the wrapping layer 10. The outer circumferential surface of the medium segment 11 and the wrapping layer 10 are in an interference fit or a transition fit, so that there is extrusion between the two, thereby increasing the friction.

[0082] In the related art, the medium segment is easily moved due to the shaking of the aerosol generating product during transportation and use, and the medium segment is easily contracted and deformed during the heating process, thereby falling off from the wrapping layer under the action of gravity, affecting the structural reliability of the aerosol generating product.

[0083] In this embodiment, the setting of the wrapping layer 10 integrates the medium segment 11, the filter segment 12, the support segment 13, the cooling segment 14, and the stopper 15, thereby improving the overall structural strength of the aerosol generating product 1. The medium segment 11 cooperates with the stopper 15 to restrict the range of movement of the medium segment 11 in the wrapping layer 10, so that the position of the medium segment 11 in the wrapping layer 10 is stable, and the probability of the medium segment 11 escaping from the wrapping layer 10 due to the shaking of the aerosol generating product 1 during transportation and use is reduced; at the same time, the probability of the medium segment 11 shrinking and deforming due to heating and falling from the wrapping layer 10 due to factors such as gravity is also reduced.

[0084] The specific components of the aerosol generating matrix are not limited herein. For example, the aerosol generating matrix may include plant components, auxiliary components, smoke generating agent components, adhesive components, and the like.

[0085] In some embodiments, 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.

[0086] In some embodiments, 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.

[0087] 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.

[0088] Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers (also called 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.

[0089] 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.

[0090] In some embodiments, the adhesive component is a natural plant-extracted, non-ionically 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-extracted, 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.

[0091] For some examples, see Figures 2 to 4 , Figure 6 to Figure 7 , Figures 9 and 10 , Figure 12 to Figure 14 The medium segment 11 has an airway hole 11c passing through at least one end of the medium segment 11 along the length direction.

[0092] In this way, the aerosol generated by the heated atomization of the medium segment 11 can be released directly from the airway holes 11c, and the aerosol has sufficient release space, thereby improving the utilization rate of the aerosol.

[0093] It can be understood that there are many situations in which the medium segment 11 has the air passage hole 11c passing through at least one end of the medium segment 11 along the length direction.

[0094] In the first type, the airway hole 11c only passes through one end of the medium segment 11 toward the stopper 15, that is, the airway hole 11c is formed as a blind hole with one end open and the other end closed. The air in the external environment can enter the airway hole 11c and carry away the aerosol generated by atomization to flow to the filter segment 12.

[0095] The second type is that the airway hole 11c only passes through one end of the medium segment 11 toward the filter segment 12, that is, the airway hole 11c is formed as a blind hole, one end is open and the other end is closed, and the air in the external environment can carry the aerosol through the airway hole 11c and flow directly from the medium segment 11 toward the filter segment 12. The third type is that the airway hole 11c passes through both ends of the medium segment 11 along the length direction, that is, the airway hole 11c passes through both ends of the medium segment 11 toward the stopper 15 and the end of the medium segment 11 toward the filter segment 12, that is, both ends of the airway hole 11c are open, and the air in the external environment enters the airway hole 11c, takes away the aerosol and flows directly to the filter segment 12, and the aerosol utilization rate is high.

[0096] The number of the airway holes 11c is not limited, and can be one, or two or more.

[0097] It is understandable that micropores are formed in the medium segment 11, and the micropores are connected to form micro airways. Some of the micropores are connected to the airway holes 11c, and the other micro airways directly pass through the air inlet and outlet ends of the medium segment 11. In this way, the aerosol can be discharged from the medium segment 11 in a variety of ways. For example, the aerosol generated by the medium segment 11 after heating can directly enter the airway holes 11c and be carried away by the air in the external environment; or, the air in the external environment directly enters the micro airway and discharges the aerosol carried by the micro airway; or, the aerosol enters the airway hole 11c from the micro airway.

[0098] It is understood that the micropores may be partially connected and partially disconnected, or all micropores may be interconnected. For example, in an embodiment in which the medium segment 11 is a particle combination, the gaps between the particles constitute the micropores, wherein the size of the micropores is determined by the gaps between the particles of the medium segment 11.

[0099] It should be noted that the airway holes 11c are holes in the macroscopic sense and can be identified by the naked eye, while the micropores are holes in the peripheral sense and cannot be identified by the naked eye.

[0100] The airway holes 11c and micropores can increase the surface area of ​​the medium segment 11, facilitate heat transfer, and improve heating efficiency. The aerosol-generating matrix in the medium segment 11 releases aerosol when heated, and is transported to the filter segment 12 under the negative pressure generated by the user's inhalation. The airway holes 11c and micropores can reduce the suction resistance of the user's inhalation, improve the user experience, and reduce the adverse effect of the condensed aerosol remaining in the medium segment 11 on the airflow.

[0101] by Figure 2 The embodiment shown is used for explanation. The stopper 15 is a solid acetate fiber structure filled with acetate fiber bundles. There are gaps between the acetate fiber bundles to form an airflow channel. When the aerosol generating product 1 is heated, external airflow such as air can enter the interior of the medium segment 11 through the airflow channel inside the stopper 15 to diffuse. The medium segment 11 has micropores inside, and the micropores are at least partially connected to each other and connected to the airway hole 11c. The aerosol generated by the medium of the medium segment 11 surrounding the airway hole 11c (i.e., the part of the medium segment 11 exposed to the airway hole 11c) directly enters the airway hole 11c, and the aerosol generated by other parts of the medium segment 11 (i.e., the part of the medium segment not exposed to the airway hole 11c) can be collected into the airway hole 11c through the micropores. In this way, during the inhalation process, the air entering from the air flow channel of the stopper 15 can carry the aerosol collected in the airway hole 11c to the first through hole 13a of the support section 13 and the second through hole 14a of the cooling section 14 for cooling, and finally enter the user's mouth after being filtered by the filter section 12.

[0102] The specific structure of the stopper 15 is not limited.

[0103] In some examples, the stopper 15 is one of: a film structure with air permeability, a mesh structure, a hollow tubular structure, and a structure formed by arranging a partition in a hollow tubular structure.

[0104] When the stopper 15 is a film structure with a breathable function, please refer to Fig.13 There are many micro holes in the film structure, and the air in the external environment can pass through the micro holes and pass through the stopper 15 to enter the medium segment 11. On the one hand, the probability of the medium segment 11 falling out of the wrapping layer 10 after heating can be reduced, and the condensate formed by the adsorbed aerosol condenses toward the first end 11a of the medium segment 11, thereby reducing the probability of the condensate falling from the wrapping layer 10 and contaminating the aerosol generating device; on the other hand, the size of the aerosol generating product 1 along the length direction can be reduced, so that the structure of the aerosol generating product 1 is more compact, or, without changing the length of the aerosol generating product 1, the length of the medium segment 11 can be increased, thereby increasing the aerosol content.

[0105] It is to be understood that micropores are pores in a microscopic sense, that is, they cannot be directly identified by the naked eye.

[0106] When the stopper 15 is a mesh structure, please refer to Fig.14 The stopper 15 has a very small size along the length direction. The stopper 15 can be formed by interweaving a plurality of criss-cross filamentary structures. The air in the external environment can enter the medium segment 11 from the gaps between the plurality of filamentary structures. On the basis of achieving stop cooperation with the medium segment 11 that has been heated and shrunk, the overall size of the aerosol generating product 1 can be effectively reduced, making the structure more compact.

[0107] When the stopper 15 is a hollow tubular structure, please refer to Fig.12 On the one hand, it can reduce the medium segment 11 from falling out of the wrapping layer 10 after being heated and contracted. On the other hand, due to its hollow structure, sufficient air from the external environment can be stored in the stopper 15, which is beneficial to the full heat release of the medium segment 11 and also convenient for the extraction of aerosol.

[0108] The hollow tubular structure can be a hollow paper tube or a hollow aluminum foil paper tube, etc.

[0109] When the stopper 15 is a structure formed by setting a partition in a hollow tubular structure, please refer to Fig.10 and Fig.11 The separator can further increase the stopping ability of the stopper 15 and provide sufficient support for the medium segment 11.

[0110] For some examples, see Fig. 9The stopper 15 is an integrated structure and has one or more through holes 15a inside. The through holes 15a penetrate the opposite ends of the stopper 15 along the length direction.

[0111] See also Fig. 9 The air in the external environment can enter the medium segment 11 through the perforation 15a, and the condensate formed by the condensation of the aerosol toward the first end 11a of the medium segment 11 can also be absorbed by the stopper 15, thereby increasing the stopping reliability of the stopper 15.

[0112] It is understandable that in some examples, at least part of the perforations 15a and the airway holes 11c are connected, so that the air in the external environment can quickly flow into the airway holes 11c after entering through the perforations 15a, thereby increasing the aerosol extraction efficiency.

[0113] In this embodiment, the method of integrally molding the stopper 15 is not limited. The stopper 15 can be an integral extrusion molded structure, the stopper 15 can be an integral injection molded structure, the stopper 15 can also be an integral die-casting structure, etc. The molding method is simple and the molding speed is fast.

[0114] For some examples, see Figures 2 to 4 , Figure 6 to Figure 7 The stopper 15 is a solid acetate fiber structure filled with acetate fiber bundles. On the one hand, it can absorb the condensate formed by the aerosol condensing toward the first end 11a of the medium segment 11, reduce the probability of the condensate escaping from the aerosol generating product 1 and causing pollution to the aerosol generating device, and facilitate the cleaning of the aerosol generating device. On the other hand, it can increase the suction resistance, so that the aerosol content generated per unit time is more reasonable, and the user experience is enhanced.

[0115] Of course, in other examples, the stopper 15 may also be a hollow tubular acetate fiber structure, and the area between the inner wall and the outer wall of the hollow tubular acetate fiber structure is filled with acetate fiber bundles.

[0116] It can be understood that acetate fiber refers to acetate fiber, also known as cellulose acetate or cellulose acetate, which is a chemically modified polymer compound obtained by esterifying the hydroxyl groups in the cellulose molecules with acetate, including diacetate fiber and triacetate fiber, which has good acid and alkali resistance and organic solvent resistance.

[0117] It is understandable that in some examples, the stopper 15 may also include an aerosol generating matrix, which can participate in heating, provide aerosol, and increase aerosol content while preventing the medium segment 11 from falling off after being deformed by heat.

[0118] The specific structure of the filtering section 12 is not limited.

[0119] For some examples, see Figures 2 to 4 , Figure 6 to Figure 7 , Figures 9 and 10 , Figure 12 to Figure 14 The filter section 12 is a solid acetate fiber structure. On the one hand, it can filter the impurities contained in the aerosol, absorb the condensate or large particle droplets formed by the condensation of the aerosol, keep the aerosol dry, and improve the user experience. On the other hand, it can also adjust the suction resistance to make the aerosol content generated per unit time more reasonable.

[0120] Of course, in other examples, the filter segment 12 may also be a porous structure formed by extrusion, a porous structure formed by injection molding, a porous structure formed by die casting, and the like.

[0121] The material of the filter segment 12 is not limited. For example, the material of the filter segment 12 includes but is not limited to PE (polyethylene), PLA (Polylactic acid, also known as polylactide), PBAT (Poly (butyleneadipate-co-terephthalate), PP (Polypropylene), acetate fiber, acrylic fiber material or one or more combinations thereof.

[0122] For other examples, see Figures 2 to 4 , Figure 6 to Figure 7 , Figures 9 and 10 , Figure 12 to Figure 14 The support section 13 includes a first hollow structure, and the hollow area of ​​the first hollow structure forms a first through hole 13a, and the first through hole 13a passes through the opposite ends of the support section 13. In this way, the aerosol can flow to the filter section 12 through the first through hole 13a, and the first through hole 13a can extend the flow path and flow area of ​​the aerosol, thereby slowing down the flow rate of the aerosol, thereby achieving a cooling effect, so that the use temperature of the aerosol is more suitable.

[0123] It is understandable that the first through hole 13a passes through opposite ends of the support section 13 along the length direction. In the embodiment of the present application, the length direction of the medium section 11, the length direction of the support section 13, the length direction of the cooling section 14, and the length direction of the filter section 12 are parallel to the length direction of the aerosol generating article 1.

[0124] The specific structure of the first hollow structure is not limited. For example, the first hollow structure can be a hollow paper tube structure or a hollow aluminum foil tube structure. The hollow paper tube structure and the hollow aluminum foil tube structure have good heat resistance, are not easily deformed by heat, and can still maintain their shape after receiving heat conduction, which can increase the structural stability of the aerosol generating product 1.

[0125] The first hollow structure may also be a hollow acetate fiber structure, a hollow aluminum foil paper tube structure, a hollow silica gel structure, etc., which are not limited here. Figure 3 The first hollow structure is a hollow acetate fiber structure, please refer to Figure 2 , the first hollow structure is a hollow paper tube structure.

[0126] For some examples, see Figure 7 and Figure 8 The support segment 13 includes a spacing rib 131, which is disposed in the first through hole 13a and connected to the first hollow structure. In this way, the structural strength of the support segment 13 itself can be increased, and the support segment 13 is convenient for connecting the structures supporting the two ends thereof, thereby increasing the overall stability of the aerosol generating article 1.

[0127] The material of the support segment 13 is not limited. For example, the material of the support segment 13 includes but is not limited to PE (polyethylene), PLA (Polylactic acid, also known as polylactide), PBAT (Poly (butyleneadipate-co-terephthalate), PP (Polypropylene), acetate fiber, acrylic fiber material or one or more combinations thereof.

[0128] The specific structure of the temperature reduction section 14 is not limited.

[0129] For some examples, see Figures 2 to 4 , Figure 6 to Figure 7 , Figures 9 and 10 , Figure 12 to Figure 14 The cooling section 14 includes a second hollow structure, and the hollow area of ​​the second hollow structure forms a second through hole 14a, and the second through hole 14a passes through the opposite ends of the cooling section 14. In this way, the aerosol can flow to the filter section 12 through the second through hole 14a, and the second through hole 14a can extend the flow path and flow area of ​​the aerosol, thereby slowing down the flow rate of the aerosol, thereby achieving a cooling effect, and making the use temperature of the aerosol more suitable.

[0130] The specific structure of the second hollow structure is not limited.

[0131] In some examples, the second hollow structure is a hollow paper tube structure or a hollow acetate fiber structure, which is light in weight and convenient for reducing the overall weight of the aerosol generating product 1, and can utilize the hollow area thereof to reduce the temperature of the aerosol. Figure 2 The second hollow structure is a hollow acetate fiber structure, please refer to Figure 3 , the second hollow structure is a hollow paper tube structure.

[0132] For some examples, see Figure 4A groove 14 b is provided inside the tube wall of the second hollow structure, and the groove 14 b passes through at least one end of the cooling section 14 along the axial direction. The groove 14 b can further reduce the temperature of the aerosol and increase the cooling effect of the cooling section 14 .

[0133] See also Figure 5 The second hollow structure may be a hollow corrugated tube structure, wherein the hollow corrugated tube has an inner wall and an outer wall, wherein the inner wall encloses a hollow space, wherein a groove 14b is provided between the inner wall and the outer wall, and wherein the cross section of the area between the inner wall and the outer wall is roughly wavy.

[0134] In some embodiments, an aroma substance is disposed in the channel 14b, so as to enrich the flavor of the aerosol and enhance the user experience.

[0135] The material of the cooling section 14 is not limited. For example, the material of the cooling section 14 includes but is not limited to PE (polyethylene), PLA (Polylactic acid, also known as polylactide), PBAT (Poly (butyleneadipate-co-terephthalate), PP (Polypropylene), acetate fiber, and one or more combinations of acrylic fiber materials.

[0136] It is understandable that the materials of the support section 13 , the cooling section 14 , and the filtering section 12 may be the same or different.

[0137] For some examples, see Figures 2 to 14 The stopper 15, the medium section 11, the support section 13, the cooling section 14 and the filter section 12 have the same cross section and the same cross section size. This is conducive to the installation and coordination between the stopper 15, the medium section 11, the support section 13, the cooling section 14 and the filter section 12, and can also reduce the size requirements of the wrapping layer 10, thereby increasing the installation reliability of the aerosol generating article 1.

[0138] The molding method of the support section 13, the cooling section 14, and the filtering section 12 is not limited. The support section 13, the cooling section 14, and the filtering section 12 can be integrally formed by extrusion molding, injection molding, die casting, etc.

[0139] For some implementations, see Figures 2 to 14 The stopper 15, the medium section 11, the support section 13, the cooling section 14 and the filtering section 12 are cylindrical and are coaxially arranged, and the length direction is the axial direction of the five.

[0140] The stopper 15, the medium section 11, the support section 13, the cooling section 14 and the filtering section 12 are connected axially, and the sections are easy to match. This can reduce the difficulty of wrapping the wrapping layer 10 outside each section, thereby reducing the difficulty of manufacturing the aerosol generating product 1.

[0141] The cross-sectional shape of the aerosol generating article 1 is not limited. For some examples, see Figures 1 to 14 , the cross-sectional shape of the aerosol generating product 1 is roughly circular, that is, the aerosol generating product 1 as a whole is roughly a columnar structure; in other examples, the cross-sectional shape of the aerosol generating product 1 is roughly rectangular, that is, the aerosol generating product 1 as a whole is roughly a rectangular column.
