[0039] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0040] This application provides an aerosol generating article 10, please refer to... Figures 1 to 3 ,as well as Figure 9 The aerosol generating article 10 includes a functional segment 12, a medium segment 11, and a first air inlet channel 13. Along the direction from the distal lip end to the proximal lip end of the medium segment 11, the medium segment 11 includes a uniformly distributed first portion 112, a second portion 113, and a third portion 114. At least one first air inlet channel 13 is disposed on the peripheral sidewall of the first portion 112; and / or, the functional segment 12 includes a first functional segment disposed at the distal lip end of the medium segment 11, and at least one first air inlet channel 13 is disposed on the peripheral sidewall between the distal lip end of the medium segment 11 and the first functional segment.

[0041] It should be noted that the aerosol generating article 10 of this application embodiment can be used for suction by ignition or by heating without combustion. In this application embodiment, the aerosol generating article 10 is described as being used for suction by heating without combustion.

[0042] This application also provides an aerosol generation system 100, please refer to... Figures 7 to 8The aerosol generation system 100 includes the aerosol generation article 10 and the aerosol generation device 20 according to any embodiment of this application.

[0043] The aerosol generating product 10 is used in conjunction with the aerosol generating device 20.

[0044] Aerosol generating article 10 is used to generate aerosols when heated for users to inhale.

[0045] In this embodiment, the aerosol-generated article 10 is generally cylindrical. The cylindrical shape can be circular (i.e., with a circular cross-section), prismatic (i.e., with a polygonal cross-section), elliptical (i.e., with an elliptical cross-section), etc., and is not limited thereto.

[0046] Here, the number of aerosol-generated products 10 can be one or more.

[0047] In the embodiments of this application, "multiple" refers to two or more items.

[0048] For example, functional segment 12 and medium segment 11 are arranged along a first direction.

[0049] The proximal end refers to the end of the aerosol generating article 10 that is closer to the user when the user uses it, while the distal end refers to the end of the aerosol generating article 10 that is farther away from the user when the user uses it. In other words, the two ends of the aerosol generating article 10 along the first direction are the proximal end and the distal end, respectively.

[0050] Please see Figures 1 to 3 The medium segment 11 includes a first part 112, a second part 113 and a third part 114 that are evenly distributed. That is, the dimensions of the first part 112, the second part 113 and the third part 114 along the first direction are equal, that is, each is equal to one-third of the dimension of the medium segment 11 along the first direction.

[0051] For example, please refer to Figures 1 to 3 Functional segment 12 includes a filter segment 124, which is located near the lip end of the medium segment 11.

[0052] For example, the aerosol generated by the heated aerosol generating article 10 can flow through the filter section 124, which can filter out large particulate components and unwanted impurities in the aerosol. That is, the aerosol generated by the heated aerosol generating article 10 is filtered through the filter section 124 and then inhaled by the user.

[0053] For example, please refer to Figures 1 to 3 Functional segment 12 also includes a second functional segment, which includes at least one of support segment 122, cooling segment 123 and filtration segment 124.

[0054] For example, the cooling section 123 is disposed between the filter section 124 and the medium section 11, and the cooling section 123 can cool the flowing aerosol.

[0055] For example, the aerosol generated by the heated aerosol generating article 10 can first flow through the cooling section 123 for cooling, and then the cooled aerosol flows through the filtration section 124, which can filter out large particles and unwanted impurities in the aerosol. That is, the aerosol generated by the heated aerosol generating article 10 is cooled and filtered sequentially through the cooling section 123 and the filtration section 124 before being inhaled by the user.

[0056] Of course, in other embodiments, functional section 12 may also include a suction resistance adjustment section. The aerosol generated by heating the aerosol generating product 10 first flows through the suction resistance adjustment section, then flows through the cooling section 123 for cooling, and after cooling, the aerosol flows through the filtration section 124, which can filter out large particles and unwanted impurities in the aerosol. That is, the aerosol generated by heating the aerosol generating product 10 passes through the suction resistance adjustment section, the cooling section 123, and the filtration section 124 in sequence for suction resistance adjustment, cooling, and filtration before being drawn in by the user.

[0057] Here, the aerosol generating article 10 includes at least a functional section 12 with a filtering effect, or a functional section 12 with effects such as regulating aerosol temperature, regulating aerosol flavor, regulating suction resistance, aggregating aerosol (aggregation section), and promoting mixing of aerosol with cold air.

[0058] It should be noted that functional segments 12 can be used in combination. Users can add or remove at least some of the functional segments 12 as needed to adjust the suction resistance.

[0059] For example, the functional segment 12 is columnar with a circular or elliptical cross-section. When the functional segment 12 contains multiple functional segments 12 with filtering and cooling effects, the longitudinal centers of each functional segment 12 are coaxially aligned.

[0060] For example, the material of functional segment 12 includes, but is not limited to, polyethylene terephthalate, paper products, polylactic acid, silicone, cellulose acetate, mineral-containing products, etc.

[0061] In one specific embodiment, please refer to Figure 2 and Figure 8 The functional section 12 also includes a support section 122, a cooling section 123 and a filter section 124 disposed near the lip end of the medium section 11. The support section 122, the cooling section 123 and the filter section 124 are arranged sequentially from the distal lip end of the aerosol generating article 10 to the proximal lip end of the aerosol generating article 10.

[0062] For example, functional segment 12 includes a front plug segment 121, which is disposed at the distal lip end of medium segment 11.

[0063] The front plug section 121 is located at the distal lip end of the medium section 11. On the one hand, during use, the front plug section 121 can effectively reduce the probability of the medium section 11 falling out of the encapsulation layer of the aerosol generating product 10. On the other hand, it can also effectively prevent the aerosol from condensing and flowing downward and remaining in the containment chamber 21 of the aerosol generating device 20, thereby causing the containment chamber 21 to be contaminated and difficult to clean. In addition, it can prevent the problem of cross-contamination of flavors when sucking in different flavored aerosol generating products 10.

[0064] For example, the material of the fore-end section 121 includes, but is not limited to, paper, non-woven fabric, rubber, polyethylene terephthalate, cellulose acetate, mineral-containing products, etc.

[0065] The heating element 22 can heat the medium section 11 in any way. For example, the heating method includes center heating (e.g.,...). Figure 4 As shown), peripheral heating (such as) Figure 5 (as shown) and edge pin heating (as shown) Figure 6 As shown, the center heating method refers to the heating element being inserted into the medium segment 11 to heat the medium segment 11 from the inside out. The peripheral heating method refers to the heating element being positioned on the periphery of the medium segment 11 to heat the medium segment 11 from the outside in. The edge heating method refers to the heating element being positioned on one side of the medium segment 11 to heat the medium segment 11 from one side to the other. These heating methods can specifically be at least one of resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, etc., and are not specifically limited here.

[0066] For example, please refer to Figures 4 to 6 The aerosol generating apparatus 20 includes a heating element 22, which is used to heat the aerosol generating article 10 to generate aerosol.

[0067] Specifically, the aerosol generating device 20 includes a housing and a power supply component 23 disposed within the housing. The housing has a receiving chamber 21. The power output part of the power supply component 23 is disposed within the receiving chamber 21 or around the side wall of the receiving chamber 21. When the portion of the aerosol generating article 10 located in the first direction range is inserted into the receiving chamber 21, the power output part transmits electrical energy to the heating element 22 in a contact or non-contact manner. The heating element 22 receives energy from the outside and generates heat, thereby heating the aerosol generating article 10 and generating aerosol.

[0068] For example, the aerosol generating device 20 includes a control module 25 for controlling the operating state of the heating element 22.

[0069] In this embodiment, the first direction does not specifically refer to the direction in which the outer contour of the aerosol-generating article 10 is longest. The length of the aerosol-generating article 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 article 10 has a cylindrical outline, the first direction is the axial direction of the aerosol generating article 10. It should be noted that even when the axial length of the aerosol generating article 10 is less than its diameter, the first direction of the aerosol generating article 10 is still the axial direction. As another example, when the aerosol generating article 10 has a cuboid outline, the first direction is still the direction defined above. The first direction of the aerosol generating article 10 can be any of the length, width, or height of the cuboid.

[0071] For example, please refer to Figure 9 The aerosol generating article 10 includes a medium segment 11 for generating aerosols. The medium segment 11 is an integral structure. The interior of the medium segment 11 has at least one air passage 111, and the air passage 111 passes through at least one end of the medium segment 11 along a first direction.

[0072] For example, the media segment 11 is a granular composite, also known as a powder composite, which is a reconstituted tobacco media, such as a reconstituted tobacco media containing smoke-generating agents, tobacco, and other components. The media segment 11 has a one-piece structure, for example, it can be formed into a one-piece structure through extrusion, injection molding, or die casting processes. 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, continuously passing through the die at the extruder outlet to form products or semi-finished products of various cross-sections. The media structure formed by extrusion molding is strip-shaped. Thus, the media segment 11 remains a one-piece medium after being heated and absorbed or after heating ceases, and is less prone to disintegration and falling off. This solves the problems of thin sheet-like, filamentous, or loose granular media segments 11 in the prior art, such as sheet detachment, shedding of filamentous components and granular components, difficulty in cleaning, and uneven composition.

[0073] The interior of the medium section 11 has at least one air passage 111, which passes through at least one end of the medium section 11 along a first direction.

[0074] The interior of the medium section 11 has at least one air passage 111, or the interior of the medium section 11 may have one air passage 111 or multiple air passages 111.

[0075] In some embodiments, the airway 111 passes through the same end of the medium section 11 along a first direction, while the other end is closed.

[0076] In other embodiments, a portion of the airway 111 passes through one end of the medium section 11 along the first direction, and another portion of the airway 111 passes through the other end of the medium section 11 along the first direction.

[0077] In some embodiments, each air passage 111 passes through both ends of the medium segment 11 along a first direction, that is, the air passage 111 extends along the first direction of the medium segment 11, and airflow can flow from one end of the medium segment 11 through the air passage 111 to the other end of the medium segment 11. Preferably, the air passage 111 is parallel to the central axis of the medium segment 11.

[0078] The walls of the air passage 111 form the inner surface of the medium section 11. The air passage 111 increases the inner surface area of ​​the medium section 11, facilitating heat transfer and improving heating efficiency. Furthermore, the medium section 11 generates aerosol upon heating, which collects in the air passage 111 and is transported to the suction end under the action of suction negative pressure. The air passage 111 reduces the suction resistance for the user, improving the user experience. It should be noted that suction resistance is positively correlated with the flow resistance of the aerosol; the lower the flow resistance of the aerosol within the medium section 11, the lower the suction resistance experienced by the user; conversely, the greater the flow resistance of the aerosol within the medium section 11, the greater the suction resistance experienced by the user.

[0079] It should be noted that the shape of the air passage 111 is not limited here. For example, on a plane perpendicular to the first direction of the medium segment 11, the cross-sectional shape of the air passage 111 may include, but is not limited to, a circle, an ellipse, a racetrack shape, or a polygon, wherein the polygon may include regular or irregular polygons.

[0080] Among them, the track shape refers to a shape similar to an athletic track, which is formed by two semicircles and two parallel straight sides connected alternately.

[0081] The cross-sectional shape of the air passage 111 refers to the cross-sectional shape of the air passage 111 as obtained by cutting along a plane perpendicular to the first direction of the medium segment 11.

[0082] In addition, the cross-sectional shape of each airway hole 111 can be exactly the same, or at least two of the airway holes 111 can have different cross-sectional shapes. For example, at least one airway hole 111 can have a circular cross-sectional shape, and at least one airway hole 111 can have a polygonal cross-sectional shape.

[0083] Of course, in other embodiments, the medium segment 11 can also be composed of traditional tobacco-type, sheet-type, or granular media.

[0084] It should be noted that the specific composition of the medium segment 11 is not limited here. For example, in some embodiments, the medium segment 11 may include plant ingredients, auxiliary ingredients, smoke-generating agents, adhesive ingredients, and fragrance ingredients, etc.

[0085] Plant-based ingredients are used to generate aerosols upon heating. Additive ingredients provide skeletal support for the plant-based ingredients. Smoke-generating ingredients produce smoke upon heating. Binder ingredients bind the various raw material components together. Flavoring ingredients provide characteristic aromas. Thus, the plant-based and smoke-generating ingredients ensure sufficient aerosol generation, while the flavoring ingredients enhance aroma release during inhalation, improving the user experience. Additive ingredients not only improve the flowability of the mixture but also create a porous structure in the medium section 11, facilitating aerosol extraction and flow. The binder ingredients ensure that the plant-based and additive ingredients form a stable mixture, preventing a loose structure.

[0086] For example, the plant-based ingredients can be one or more of the following: raw tobacco leaves, tobacco fragments, tobacco stems, tobacco dust, and aromatic plants, which are powdered after being crushed. The plant-based ingredients are the core source of the aroma, and the endogenous substances within them can provide users with a sense of physiological satisfaction. Endogenous substances, such as alkaloids, enter the bloodstream and promote the pituitary gland to produce dopamine, thereby achieving physiological satisfaction.

[0087] For example, the auxiliary components can be one or more combinations of inorganic fillers, lubricants, and emulsifiers. The inorganic fillers include one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. Inorganic fillers provide skeletal support for the plant components and also have micropores, which can increase the porosity of the medium section 11, thereby increasing the aerosol release rate. Lubricants include one or more combinations of candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. Lubricants can increase the flowability of the plant component powder, reduce the friction between the plant component powders, make the overall density of the plant component powder distribution more uniform, and also reduce the pressure required for extrusion molding, reducing die wear. Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers can, to a certain extent, slow down the loss of aroma substances during storage, increase the stability of aroma substances, and improve the sensory quality of the product.

[0088] For example, the smoke-generating agent may include one or more combinations of: monohydric alcohols (such as menthol); polyhydric alcohols (such as propylene glycol, glycerol, triethylene glycol, 1,3-butanediol, and tetraethylene glycol); esters of polyhydric alcohols (such as triacetin, triethyl citrate, mixtures of diacetins, triethyl citrate, methylbenzyl benzoate, and triglyceride); monocarboxylic acids; dicarboxylic acids; polycarboxylic acids (such as lauric acid and myristic acid) or aliphatic esters of polycarboxylic acids (such as dimethyl dodecanoate, dimethyl tetradecanoate, erythritol, 1,3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, triacetin, mesoerythritol, mixtures of diacetins, diethyl octanoate, triethyl citrate, methylbenzyl benzoate, phenylacetic acid, ethyl vanillate, triglyceride, and lauryl acetate).

[0089] For example, the adhesive component achieves close contact with the component raw materials through wetting at the interface, generating intermolecular attraction, thereby binding the component raw materials, such as powders, liquids, etc. The adhesive component can be one or more combinations of natural plant extracts, non-ionic modified viscous polysaccharides, including tamarind polysaccharides, guar gum, and modified cellulose (such as carboxymethyl cellulose). The adhesive is used to bind particles together, preventing them from easily falling apart, and also improves the water resistance of the media segment 11, and is harmless to the human body.

[0090] For example, flavoring ingredients are used to provide characteristic aromas, such as hay, roasted sweetness, or solid or liquid substances of nicotine. Flavoring ingredients may include one or more combinations of tobacco or other plants, aromatic plant extracts, extracts, essential oils, and absolutes; flavoring ingredients may include one or more combinations of monomeric aroma substances, such as megastigmatrienone, neophytadiene, geraniol, nerol, etc.

[0091] It should be noted that the medium segment 11 has micropores, which are interconnected to form micro-air channels communicating with the airway holes 111. That is, the micro-air channels are connected to the airway holes 111, and since the micro-air channels are formed by the interconnection of micropores, the micropores are connected to the airway holes 111. Furthermore, it can be understood that the interconnection between micropores can be partial, with some micropores not connected, or all micropores can be interconnected. For example, in an embodiment where the medium segment 11 is a particle aggregate, the gaps between the particles constitute the micropores. The size of the micropores is determined by the gaps between the particles.

[0092] The air ducts 111 and micro-air channels can increase the surface area of ​​the medium section 11, facilitating heat transfer and improving heating efficiency. When the medium in the medium section 11 is heated, it releases aerosols, which are collected in the air ducts 111 through the gaps between the wall materials or the micro-air channels. The aerosols released by the atomized medium exposed to the air ducts 111 (i.e., the atomized medium located on the inner wall surface of the air ducts 111) can be directly released into the air ducts 111. The aerosols between adjacent air ducts 111 can also flow between each other through the micro-air channels and be transported to the suction end under the action of suction negative pressure.

[0093] It should be noted that the airway pore 111 mentioned above is a pore in a macroscopic sense, while the micropore is a pore in a microscopic sense. The cross-sectional area of ​​the airway pore 111 is much larger than that of the micropore.

[0094] For example, the cross-sectional area of ​​the airway 111 is at least 20 times the cross-sectional area of ​​the micropore. With the micropore size remaining approximately constant, a cross-sectional area less than 20 times the micropore size would result in an excessively small airway 111, making it difficult for aerosol to be released from the inner wall of the airway 111, leading to high suction resistance and a decreased suction experience. Therefore, in this embodiment, when the cross-sectional area of ​​the airway 111 is greater than or equal to 20 times the cross-sectional area of ​​the micropore, the rate of aerosol release from the inner wall of the airway 111 is ensured, suction resistance is reduced, and the user's suction experience is improved.

[0095] Please see here. Figure 3 At least one first air intake channel 13 is provided on the peripheral sidewall of the first part 112, that is, the first air intake channel 13 is formed in the medium section 11, so that external airflow can enter the medium section 11 through the first air intake channel 13.

[0096] The medium section 11 has a first air intake passage 13 extending laterally and an air passage 111 extending longitudinally, the air passage 111 penetrating at least one end face of the medium section 11 along the longitudinal direction. Exemplarily, the first direction is, for example, the longitudinal direction of the medium section 11, that is, the air passage 111 extends longitudinally along the medium section 11 and the first air intake passage 13 extends laterally along the medium section 11.

[0097] At least one end of the first air intake passage 13 penetrates the circumferential surface of the medium section 11 to form an air intake.

[0098] By forming air passages 111 in the medium section 11, with the air passages 111 penetrating at least one end face of the medium section 11 along its longitudinal direction, the aerosol within the air passages 111, under the action of suction negative pressure, not only facilitates the orderly extraction and delivery of aerosols but also reduces suction resistance for the user, improving the user experience. By forming a first air inlet channel 13 within the medium section 11, not only is it beneficial for airflow to diffuse laterally within the medium section 11, thereby improving the uniformity of aerosol extraction and resulting in good taste consistency; the first air inlet channel 13 also increases the specific surface area of ​​the medium section 11, which is beneficial for heat transfer, improving heating efficiency and increasing aerosol extraction efficiency. By forming an air inlet on the circumferential surface of the medium section 11, external airflow, such as air, can enter the first air inlet channel 13 through the air inlet for diffusion, thus extracting aerosols.

[0099] It should be noted that the first intake channel 13 may be formed only on the medium section 11, or only between the distal lip of the medium section 11 and the functional section 12, or both on the medium section 11 and between the distal lip of the medium section 11 and the functional section 12.

[0100] Please see Figures 1 to 3 Here, by defining a first air intake channel 13 between the distal lip of the medium section 11 and the functional section 12, that is, at least one row of first air intake channels 13 is formed at the joint between the distal lip of the medium section 11 and the functional section 12, it is beneficial to reduce the impact on the medium section 11 and the functional section 12 when forming the first air intake channel 13.

[0101] For example, the first intake passage 13 is defined between the distal lip of the medium section 11 and the front plug section 121.

[0102] This application provides an aerosol generating article 10, including a functional section 12, a medium section 11, and a first air inlet channel 13. The medium section 11 is used to generate aerosols. The first air inlet channel 13 is formed at the distal lip of the medium section 11, or it is defined between the distal lip of the medium section 11 and the functional section 12. That is, the first air inlet channel 13 is located at the distal lip of the aerosol generating article 10. During suction, external airflow can enter the aerosol generating article 10 through the first air inlet channel 13. In this way, on the one hand, the airflow circulation pressure can be adjusted, thereby adjusting the suction resistance of the aerosol generating system 100. On the other hand, it helps to improve the slow extraction efficiency of aerosols generated at the distal lip of the medium section 11, that is, it improves the aerosol extraction efficiency. In addition, the airflow entering the aerosol generating article 10 through the first air inlet channel 13 can cool the aerosols, thereby reducing the transport temperature of the extracted aerosols.

[0103] In some embodiments, please refer to Figures 1 to 3 The aerosol generating article 10 includes a first coating layer 15, which wraps around the circumferential surfaces of the medium section 11 and the front plug section 121. At least a portion of the first air intake channel 13 is disposed in the first coating layer 15, and the circumferential direction of the front plug section 121 is perpendicular to the first direction.

[0104] The first wrapping layer 15 has a certain degree of hardness, which can play a certain protective role for the medium section 11, reduce the surface area of ​​the medium section 11 directly exposed to the outside world, thereby reducing the probability of the medium section 11 becoming damp and deteriorating due to contact with air. At the same time, it reduces the probability of the medium section 11 coming into contact with other components in the aerosol generating device 20 and causing pollution.

[0105] For example, the first air intake channel 13 passes through the first wrapping layer 15 so that external airflow can enter the aerosol generating article 10 through the first air intake channel 13.

[0106] It should be noted that the dielectric segment 11 and the first coating layer 15 can be an integral structure. That is, the dielectric segment 11 and the first coating layer 15 are different parts of a single structure. In this way, on the one hand, the relative position of the dielectric segment 11 and the first coating layer 15 is fixed, which can reduce the probability of the dielectric segment 11 and the first coating layer 15 separating due to factors such as temperature changes and vibration during the use of the aerosol-generated product 10; on the other hand, the dielectric segment 11 and the first coating layer 15 can be prepared simultaneously, thereby reducing manufacturing steps and improving production efficiency.

[0107] For example, the integral structure of the media section and the first wrapping layer 15 is formed by a co-extrusion process.

[0108] Of course, the medium segment 11 and the first wrapping layer 15 can also be a separate structure.

[0109] Of course, the front plug section 121 and the first wrapping layer 15 can be an integral structure or a separate structure.

[0110] In some embodiments, please refer to Figures 1 to 3 The aerosol generating article 10 includes a second coating layer 16, which covers at least the circumferential surfaces of the support section 122, the cooling section 123, and the filter section 124.

[0111] The second wrapping layer 16 has a certain degree of hardness, which can provide a certain degree of protection for the functional section 12 and wrap the support section 122, cooling section 123 and filter section 124 into a whole. That is, the second wrapping layer 16 is used to connect the support section 122, cooling section 123 and filter section 124.

[0112] For example, the second wrapping layer 16 also wraps around at least a portion of the circumferential surface of the first wrapping layer 15, that is, the second wrapping layer 16 is used to connect the medium segment 11 and a portion of the support segment 122.

[0113] In some embodiments, please refer to Figure 2 The aerosol generating product 10 has a second air inlet channel 14, which is disposed on the peripheral sidewall of the second functional section.

[0114] Here, in the embodiment where the second wrapping layer 16 is provided, the second air intake channel 14 may pass through the peripheral sidewall of the second functional section and the peripheral sidewall of the second wrapping layer 16.

[0115] The second air intake passage 14 is provided with a peripheral wall of the second functional section, which may refer to the peripheral wall passing through the support section 122, the cooling section 123 and / or the filter section 124.

[0116] In this way, on the one hand, the airflow circulation pressure can be adjusted to regulate the suction resistance of the aerosol generation system 100; on the other hand, the airflow entering the aerosol generation product 10 through the second air inlet channel 14 can cool the aerosol, thereby reducing the transmission temperature of the extracted aerosol.

[0117] Furthermore, by adjusting the number, geometry, area, and other parameters of the first air inlet channel 13 at the distal lip end and the second air inlet channel 14 at the proximal lip end of the aerosol generating product 10, the air inlet ratio at the distal and proximal lip ends of the aerosol generating product 10 can be effectively changed, thereby affecting the generation and flow of aerosols, which in turn helps to improve the extraction efficiency of aerosols and the taste experience.

[0118] In some embodiments, please refer to Figure 2 The cooling section 123 has a third air intake channel 1231 extending in the first direction, and the cooling section 123 has a second air intake channel 14. The third air intake channel 1231 is connected to the outside of the aerosol generating product 10 through the second air intake channel 14.

[0119] Here, the cooling section 123 forms a second air intake channel 14 that passes through the side wall of the third air intake channel 1231. That is, the second air intake channel 14 passes through the side wall of the third air intake channel 1231 and is connected to the third air intake channel 1231.

[0120] In this embodiment, the third air intake channel 1231 is connected to the outside of the functional section 12 through the second air intake channel 14. External air can enter the third air intake channel 1231 through the second air intake channel 14, which is beneficial to cooling the aerosol in the third air intake channel 1231, thereby further improving the cooling effect of the cooling section 123.

[0121] By adding a lateral air intake channel (i.e., the second air intake channel 14), the internal and external environmental pressure of the airflow circulation is adjusted, which helps to improve the problem of slow aerosol extraction efficiency in the front section of the bottom air intake aerosol generation device 20 under the circumferential heating mode, reduces the transmission temperature of the extracted aerosol, and adjusts the suction resistance (RTD) of the aerosol generation system 100.

[0122] In some embodiments, please refer to Figure 2 Functional section 12 also includes a fragrance enhancer 17, which is disposed within the filter section 124.

[0123] For example, the flavoring component 17 is a capsule structure storing a flavoring substance. The flavoring substance in the capsule is released under the action of an external force.

[0124] After the aerosol product 10 is extracted, the aerosol passes through the flavoring element 17. The heat inherent in the aerosol itself exchanges heat with the aroma-producing components in the flavoring element 17, causing the aerosol temperature to drop. In addition, the aroma-producing components are released and mixed with the aerosol, improving the richness and consistency of the aroma in the aerosol. At the same time, in addition to having a high aroma-carrying capacity, the flavoring element 17 also has a cooling effect.

[0125] The fragrance material loaded on the fragrance enhancer 17 refers to the ability of the fragrance material to penetrate, be absorbed, or adhere to the interior of the fragrance enhancer 17.

[0126] It should be noted that the specific components of the flavoring are not limited here.

[0127] For example, the fragrance ingredient may include monomeric fragrance substances, such as one or more combinations of megastigmatrienone, neophytadiene, geraniol, nerol, etc.

[0128] For example, this can also be achieved by embedding a capsule containing a fragrance substance in the fragrance enhancer 17.

[0129] For example, the second air intake channel 14 is positioned close to the fragrance enhancer 17, which helps to assist in the release of fragrance.

[0130] In some embodiments, please refer to Figures 1 to 4 The aerosol generating article 10 includes at least one air inlet channel group, and a single air inlet channel group includes 1 to 30 first air inlet channels 13. When there are multiple first air inlet channels 13 in a single air inlet channel group, each first air inlet channel 13 in the single air inlet channel group is arranged along the circumference of the aerosol generating article 10, and the circumference of the aerosol generating article 10 is perpendicular to the first direction.

[0131] Here, the number of intake channel groups can be one or more.

[0132] In the embodiments of this application, "multiple" refers to two or more items.

[0133] For example, when there are multiple intake channel groups, each intake channel group is arranged along a first direction.

[0134] The number of first air intake channels 13 in a single air intake channel group can be 1, 3, 5, 8, 10, 12, 13, 15, 18, 20, 22, 23, 25, 28, 30, etc.

[0135] By arranging the first air intake channels 13 of a single air intake channel group along the circumference of the aerosol generating article 10, the first air intake channels 13 are evenly distributed along the circumference of the aerosol generating article 10, which helps to improve the uniformity of air intake. In addition, by setting a single air intake channel group to include 1 to 30 first air intake channels 13, the appropriate number of first air intake channels 13 within this range can both give the aerosol generating article 10 a certain structural strength, improve the problem of easy breakage caused by too many openings, and give the aerosol generating article 10 a certain air intake volume.

[0136] In some embodiments, the maximum cross-sectional area of ​​a single first air intake channel 13 is 0.0064 mm. 2 -0.25mm 2 .

[0137] The maximum cross-sectional area of ​​a single first air intake channel 13 can be 0.0064 mm². 2 0.008mm 2 0.01mm 2 0.04mm 2 0.05mm 2 0.08mm 2 0.1mm 2 0.12mm 2 0.13mm 2 0.15mm 2 0.18mm 2 0.2mm 2 0.22mm 2 0.23mm 2 0.25mm 2 The point value of any one of them or the point value between any two.

[0138] It should be noted that the maximum cross-sectional area of ​​a single first intake passage 13 refers to the area of ​​the largest cross-section among all the cross-sections of that single first intake passage 13. Here, the cross-section of a single first intake passage 13 is its flow section.

[0139] With a fixed intake area, the smaller the cross-sectional area of ​​a single first intake channel 13, the more first intake channels 13 need to be set up; the larger the cross-sectional area of ​​a single first intake channel 13, the fewer first intake channels 13 need to be set up.

[0140] In this embodiment, the maximum cross-sectional area of ​​a single first air intake channel 13 is set to 0.0064 mm. 2 -0.25mm 2 While ensuring that the aerosol generating product 10 has a certain air intake efficiency, it can also ensure that the aerosol generating product 10 has a certain structural strength. In addition, by controlling the number of the first air intake channels 13, the production efficiency of the aerosol generating product 10 can be improved.

[0141] Preferably, the maximum cross-sectional area of ​​a single first air intake channel 13 is 0.01 mm². 2 -0.09mm 2 .

[0142] While ensuring that the aerosol generating product 10 has a certain air intake efficiency, the production efficiency of the aerosol generating product 10 is further improved.

[0143] More preferably, the maximum cross-sectional area of ​​a single first air intake passage 13 is 0.01 mm². 2 -0.04mm 2 .

[0144] While ensuring that the aerosol generating product 10 has a certain air intake efficiency, the production efficiency of the aerosol generating product 10 is further improved.

[0145] For example, the shape of the first air intake channel 13 can be a variety of regular or irregular geometric shapes.

[0146] Preferably, the first air intake channel 13 has a regular geometric shape, which facilitates processing by a drilling device.

[0147] More preferably, the first air intake passage 13 is circular or elliptical, which can provide a larger air intake volume within the same area.

[0148] In some embodiments, please refer to Figure 2 The aerosol generating article 10 includes at least one second air inlet channel group, and a single second air inlet channel group includes 3 to 20 second air inlet channels 14. When there are multiple second air inlet channels 14 in a single second air inlet channel group, each second air inlet channel 14 in the single second air inlet channel group is arranged along the circumference of the aerosol generating article 10, and the circumference of the aerosol generating article 10 is perpendicular to the first direction.

[0149] Here, the number of second air intake channel groups can be one or more.

[0150] In the embodiments of this application, "multiple" refers to two or more items.

[0151] For example, when there are multiple second intake channel groups, each second intake channel group is arranged along a first direction.

[0152] The number of second intake channels 14 in a single second intake channel group can be 3, 5, 8, 10, 12, 13, 15, 18, 20, etc.

[0153] By arranging the second air intake channels 14 of a single second air intake channel group along the circumference of the aerosol generating article 10, the second air intake channels 14 are evenly distributed along the circumference of the aerosol generating article 10, which helps to improve the uniformity of air intake. Furthermore, by setting a single second air intake channel group to include 3 to 20 second air intake channels 14, this appropriate number of second air intake channels 14 can both ensure that the aerosol generating article 10 has a certain structural strength, improving the problem of easy breakage due to excessive openings, and also ensure that the aerosol generating article 10 has a certain air intake volume.

[0154] Preferably, a single second air intake channel group includes 5 to 15 second air intake channels 14.

[0155] For example, the shape of the second air intake passage 14 can be a variety of regular or irregular geometric shapes.

[0156] Preferably, the second air intake channel 14 has a regular geometric shape, which facilitates processing by a drilling device.

[0157] More preferably, the second air intake channel 14 is square (square and rectangular) to provide a certain aroma resolution capability.

[0158] It should be noted that the cross-sectional shape of the front plug section 121 is not restricted here.

[0159] In some embodiments, please refer to Figures 1 to 3 On a plane perpendicular to the axial direction of the front plug section 121, the cross-section of the front plug section 121 is circular.

[0160] In other embodiments, the cross-sectional shape of the front plug section 121 is non-circular in a plane perpendicular to the axial direction of the front plug section 121.

[0161] In one embodiment, the material of the first wrapping layer 15 and / or the second wrapping layer 16 includes at least one of polylactic acid, fiber paper, polyethylene, and polyethylene terephthalate.

[0162] On the one hand, the first wrapping layer 15 and / or the second wrapping layer 16 of this material have a certain toughness, so that they can be wound around the filling part to obtain the front plug section 121; on the other hand, the first wrapping layer 15 and / or the second wrapping layer 16 of this material also have a certain strength, which can reduce the probability of deformation of the front plug section 121, that is, it is beneficial to improve the yield of the front plug section 121.

[0163] In some embodiments, please refer to Figures 1 to 3 The functional segment 12 and the aerosol generating product 10 are cylindrical and coaxially arranged, with the first direction being the axial direction of the functional segment 12 and the aerosol generating product 10.

[0164] By setting both the functional segment 12 and the aerosol generating article 10 as cylinders and arranging them sequentially along the axial direction of the functional segment 12 and the aerosol generating article 10, the structure of the aerosol generating article 10 can be made more compact, improving the user experience.

[0165] In some embodiments, please refer to Figures 4 to 8 The aerosol generating device 20 is provided with a receiving chamber 21 and a fourth air inlet channel 24 connected to the receiving chamber 21. The receiving chamber 21 is used to contain at least part of the aerosol generating product 10. The first air inlet channel 13 is connected to the outside of the aerosol generating device 20 through the fourth air inlet channel 24.

[0166] For example, the fourth air intake channel 24 is provided at the bottom or side of the receiving compartment 21.

[0167] Please see Figures 4 to 8 The bottom of the receiving chamber 21 may have a cavity area 211. After the aerosol-generated product 10 is inserted into the receiving chamber 21, at least one first air intake channel 13 can be used normally. External airflow can enter the cavity area 211 through the fourth air intake channel 24, and then enter the first air intake channel 13.

[0168] For example, please refer to Figure 8 The aerosol generating device 20 may have at least one fourth air inlet channel 24 on the side of the receiving chamber 21 for supplying airflow to the first air inlet channel 13 of the aerosol generating product 10. The fourth air inlet channel 24 is aligned with the first air inlet channel 13.

[0169] For example, there are multiple first air intake channels 13, and the aerosol generating article 10 is rotatable in the aerosol generating device 20. After each rotation, at least one first air intake channel 13 is aligned with the fourth air intake channel 24.
