Technical Field

[0001] This application relates to the field of smoke-generating products, and in particular to an aerosol-generating product and an aerosol-generating system. Background Technology

[0002] Aerosol-generating products can form aerosols through ignition or through heated-but-not-burn (HNB) methods. In HNB aerosol-generating products, an external heat source heats the product just enough to release aerosols without combustion.

The ratio of the length to the diameter of the medium segment is greater than or equal to 1 and less than or equal to 10, which improves the ease of use of the medium segment and further ensures that the aerosol generating article has a certain amount of smoke.

[0030] Furthermore, the medium section has a one-piece structure, which can be formed through processes such as extrusion, die casting, or injection molding to improve the uniformity of the medium section's density, further enhancing the stability of aerosol release and suction. The medium section has at least one air passage hole inside, the wall of which forms the inner surface of the medium section. This air passage hole increases the inner surface area of ​​the medium section, facilitating heat transfer and improving heating efficiency. The medium section generates aerosol upon heating, which collects in the air passage hole and is transported to the suction end under the negative pressure of suction. The air passage hole reduces the user's suction resistance, resulting in a larger vapor volume and improved stability of aerosol release and suction. Attached Figure Description

[0045] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0046] This application provides an aerosol generating article 10, please refer to... Figures 1 to 5 The aerosol generating article 10 includes a functional segment 14 and a medium segment 11 arranged along a first direction. The medium segment 11 is an integral structure and has at least one air passage 111 inside. The air passage 111 passes through at least one end of the medium segment 11 along the first direction. The functional segment 14 is located near the lip end of the aerosol generating article 10. The diameter of the medium segment 11 is greater than or equal to 4 mm and less than or equal to 7 mm. The ratio of the length of the medium segment 11 to the diameter of the medium segment 11 is greater than or equal to 1 and less than or equal to 10.

[0047] 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.

[0048] This application also provides an aerosol generation system 100, which includes an aerosol generation article 10 and an aerosol generation device 20 according to any embodiment of this application.

[0049] The aerosol generating product 10 is used in conjunction with the aerosol generating device 20.

[0050] Aerosol generating article 10 is used to generate aerosols when heated for users to inhale.

[0051] 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.

[0052] Here, the number of aerosol-generated products 10 can be one or more.

[0053] In the embodiments of this application, "multiple" refers to two or more items.

[0054] 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.

[0055] For example, please refer to Figures 1 to 4 Function segment 14 includes a first function segment 141, which is configured as a filter segment.

[0056] For example, the aerosol generated by the heated aerosol generating article 10 can flow through a filtration section, 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 filtration section and then inhaled by the user.

[0057] For example, please refer to Figures 1 to 4 Functional segment 14 includes a second functional segment 142. A first functional segment 141 is disposed at one end of the second functional segment 142 away from the medium segment 11. The second functional segment 142 includes at least one of a flow guiding segment, a cooling segment, a gathering segment, a support segment, a fragrance carrying segment, or a filtration segment.

[0058] For example, the second functional segment 142 includes a cooling segment disposed at at least one end of the filter segment along the first direction, and the cooling segment can cool the flowing aerosol.

[0059] For example, the aerosol generated by the heated aerosol generating article 10 can first flow through a cooling section for cooling, and then the cooled aerosol flows through a filtration section, 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 in sequence through the cooling section and the filtration section before being inhaled by the user.

[0060] Of course, in other embodiments, functional segment 14 may also include a suction resistance adjustment segment. The aerosol generated by heating the aerosol generating product 10 first flows through the suction resistance adjustment segment, then through the cooling segment for cooling, and finally through the filtration segment. The filtration segment 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 segment, the cooling segment, and the filtration segment in sequence for suction resistance adjustment, cooling, and filtration before being drawn in by the user.

[0061] Here, the aerosol generating article 10 includes at least a functional section 14 with a filtering effect, or a functional section 14 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.

[0062] It should be noted that functional segments 14 can be used in combination. Users can add or remove at least some of the functional segments 14 as needed to adjust the suction resistance.

[0063] For example, the functional segment 14 is columnar with a circular or elliptical cross-section. When the functional segment 14 contains multiple functional segments 14 that have filtering or cooling effects, the longitudinal centers of each functional segment 14 are aligned coaxially.

[0064] For example, the material of functional segment 14 includes, but is not limited to, polyethylene terephthalate, paper products, polylactic acid, silicone, cellulose acetate, mineral-containing products, etc.

[0065] The heating element 22 can heat the medium segment 11 in any way. Exemplarily, the heating methods include center heating and peripheral heating. Center heating refers to the heating element being inserted into the medium segment 11 to heat it from the inside out. Peripheral heating refers to the heating element being positioned around the medium segment 11 to heat it from the outside in. 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 Figure 1 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 disposed within the housing. The housing has a receiving chamber 21. The power output section of the power supply component 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 section 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] 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.

[0069] 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.

[0070] For example, 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.

[0071] 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.

[0072] The interior of the medium section 11 has at least one air passage 111, see [link / reference]. Figures 2 to 4 The air passage 111 passes through at least one end of the medium section 11 along the first direction.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] Of course, in other embodiments, the medium segment 11 can also be composed of traditional tobacco-type, sheet-type, or granular media.

[0083] For example, please refer to Figures 1 to 4 The aerosol generating product 10 includes an outer packaging layer 13, which wraps around the circumferential surface of the medium section 11.

[0084] The outer packaging layer 13 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.

[0085] It should be noted that the medium segment 11 and the outer packaging layer 13 can be an integral structure. That is, the medium segment 11 and the outer packaging layer 13 are different parts of a single structure. In this way, on the one hand, the relative position of the medium segment 11 and the outer packaging layer 13 is fixed, which can reduce the probability of the medium segment 11 and the outer packaging layer 13 separating due to factors such as temperature changes and vibration during the use of the aerosol-generated product 10; on the other hand, the medium segment 11 and the outer packaging layer 13 can be manufactured simultaneously, thereby reducing manufacturing steps and improving production efficiency.

[0086] For example, the integrated structure of the media section and the outer packaging layer 13 is formed by a co-extrusion process.

[0087] Of course, the medium segment 11 and the outer packaging layer 13 can also be a separate structure.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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).

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] The diameter of the medium segment 11 is greater than or equal to 4 mm and less than or equal to 7 mm. For example, it is a point value of any one of 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, and 7 mm, or a point value between any two of them.

[0100] Here, the larger the diameter of the medium section 11, the more effective substances it contains and the greater the amount of smoke. However, during the peripheral heating process, the time required for heat to be transferred to the center of the medium section 11 is longer. Conversely, the smaller the diameter of the medium section 11, the shorter the time required for heat to be transferred to the center of the medium section 11 during the peripheral heating process.

[0101] By making the diameter of the medium segment 11 greater than or equal to 4 mm and less than or equal to 7 mm, it is called a thin-sized medium segment 11. The cavity volume of the thin-sized medium segment 11 is smaller than that of the conventional-sized medium segment 11, which helps to reduce the air flowing inside the medium segment 11, improves the heating uniformity and stability of the medium segment 11, improves the extraction efficiency and utilization rate of the medium segment 11, enhances the consistency of aerosol release, improves aerosol quality, and also reduces energy consumption.

[0102] The ratio of the length of the medium segment 11 to the diameter of the medium segment 11 is greater than or equal to 1 and less than or equal to 10. For example, it is a point value of any one of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or a point value between any two.

[0103] This application provides an aerosol generating article 10, including a functional segment 14 and a medium segment 11. The medium segment 11 is used to generate aerosols. By setting the diameter of the medium segment 11 to be greater than or equal to 4 mm and less than or equal to 7 mm, this appropriate diameter range not only ensures that the aerosol generating article 10 has a certain amount of smoke, but also improves the heating uniformity and stability of the medium segment 11, increases the extraction efficiency of the medium segment 11, enhances the consistency of aerosol release, improves aerosol quality, and reduces energy consumption. The ratio of the length to the diameter of the medium segment 11 is greater than or equal to 1 and less than or equal to 10, which improves the ease of use of the medium segment 11 and further ensures that the aerosol generating article 10 has a certain amount of smoke.

[0104] Furthermore, the medium section 11 is a one-piece structure, which can be formed by processes such as extrusion, die casting, or injection molding to improve the uniformity of the density of the medium section 11, thereby further improving the stability of aerosol release and suction. The medium section 11 has at least one air passage 111 inside, and the wall of the air passage 111 forms 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. 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, resulting in a larger vapor volume and improving the stability of aerosol release and suction.

[0105] In some embodiments, the length of the aerosol-generating article 10 is greater than or equal to 40 mm and less than or equal to 90 mm.

[0106] The length of the aerosol-generated product 10 can be any one of 40mm, 50mm, 60mm, 70mm, 80mm, or 90mm, or any combination thereof.

[0107] In some embodiments, the length of the medium segment 11 is greater than or equal to 8 mm and less than or equal to 40 mm.

[0108] The length of the medium segment 11 can be any one of 8mm, 10mm, 15mm, 20mm, 22mm, 25mm, 30mm, 32mm, 35mm, 38mm, or 40mm, or any combination thereof.

[0109] The longer the medium section 11 is, the more effective substances it contains and the greater the amount of smoke. The shorter the medium section 11 is, the more it is conducive to improving the ease of use and production efficiency of the medium section 11.

[0110] By setting the length of the medium segment 11 within this range, the medium segment 11 can have a certain amount of smoke, while also improving the ease of use and production efficiency of the medium segment 11.

[0111] In some embodiments, the ratio of the length of the medium segment 11 to the length of the aerosol-generated article 10 is greater than or equal to 0.1 and less than or equal to 0.6.

[0112] The ratio of the length of the medium segment 11 to the length of the aerosol-generated product 10 can be any one of 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.5, 0.6 or any value between the two.

[0113] The greater the ratio of the length of the medium section 11 to the length of the aerosol generating product 10, the more effective substances it contains and the greater the amount of smoke. The smaller the ratio of the length of the medium section 11 to the length of the aerosol generating product 10, the more beneficial it is to improve the ease of use and production efficiency of the medium section 11.

[0114] In some embodiments, the suction resistance of the aerosol generating article 10 is greater than or equal to 15 mmWG and less than or equal to 50 mmWG.

[0115] Here, mmWG is a unit of static pressure, representing millimeters of water column. That is to say, the suction resistance of the aerosol-generated product 10 is greater than or equal to 15 millimeters of water column and less than or equal to 50 millimeters of water column.

[0116] The suction resistance of the aerosol-generating article 10 can be any one of 15mmWG, 20mmWG, 25mmWG, 30mmWG, 35mmWG, 40mmWG, 45mmWG, 50mmWG, or any value between two of them.

[0117] The suction resistance (RTD) mentioned here refers to open suction resistance or dynamic suction resistance, because the airflow of the aerosol generating product 10 enters from the bottom and side openings respectively, and the airflow ratio of the side intake is the ventilation rate.

[0118] By setting the suction resistance of the aerosol generating article 10 to be greater than or equal to 15 mmWG and less than or equal to 50 mmWG, it is beneficial to keep the suction resistance of the aerosol generating article 10 within an appropriate range, which can make the suction resistance of the aerosol generating article 10 appropriate and improve the user experience.

[0119] In some embodiments, please refer to Figures 1 to 4 The aerosol generating article 10 includes a front plug section 12, which is disposed at one end of the medium section 11 and located at the distal lip end of the aerosol generating article 10. The front plug section 12 includes a wrapping layer 121 and a filling portion. The filling portion is formed by multiple bending of a layered filling member 122 and is in a pleated shape. The filling portion is disposed within the wrapping layer 121 to form a channel 123 extending from one end of the front plug section 12 to the other end within the wrapping layer 121.

[0120] For example, the outer packaging layer 13 surrounds the periphery of the front plug section 12 and the medium section 11.

[0121] The front plug section 12 is located at one end of the medium section 11 and at the distal lip of the aerosol generating product 10. On the one hand, during use, the front plug section 12 can effectively reduce the probability of the medium section 11 falling out of the outer packaging layer 13; on the other hand, it can also effectively prevent the aerosol from condensing and flowing downward and remaining in the receiving chamber 21 of the aerosol generating device 20, thereby causing the internal contamination of the receiving chamber 21 and making it difficult to clean, and also preventing the problem of cross-contamination of flavors when sucking in different flavored aerosol generating products 10.

[0122] For example, the material of the fore-end section 12 includes, but is not limited to, paper, non-woven fabric, rubber, polyethylene terephthalate, cellulose acetate, mineral-containing products, etc.

[0123] The shape of the cross-section of the outer packaging layer 13 is not limited in a plane perpendicular to the axis of the aerosol-generating article 10. Generally, please refer to [link to relevant documentation]. Figures 1 to 4 The outer packaging layer 13 has a circular cross-section. Circular means that the outer packaging layer 13 has a wall thickness, therefore the cross-sectional shape of its inner and outer circumferential walls is circular. It can be understood that the outer packaging layer 13 is typically made of paper material with a relatively small thickness, for example, less than 1 mm; therefore, its cross-sectional shape can also be considered circular. In other words, the outer wall surface of the outer packaging layer 13 is cylindrical. With this structure, the aerosol generating product 10 of the outer packaging layer 13 has an overall cylindrical structure. The cylindrical aerosol generating product 10 can be inserted into the receiving chamber 21 at various angles along its circumference, thus facilitating user use.

[0124] The front plug section 12 includes a wrapping layer 121 and a filling part. The filling part is formed by repeatedly bending a layered filling member 122 and is in a pleated shape. The filling part is disposed in the wrapping layer 121 to form a channel 123 extending from one end of the front plug section 12 to the other end within the wrapping layer 121.

[0125] Please see Figure 5 The pleated filling section, channel 123 extends along the axial direction of the front plug section 12. It can be understood that the cross-section of channel 123 is bent in a plane perpendicular to the axial direction of the front plug section 12.

[0126] External airflow can flow through channel 123 to medium section 11, thereby reducing the suction resistance of the front plug section 12 on the aerosol extraction. At the same time, since the filling part has a pleated shape, it has a better adsorption effect, which helps to reduce the probability that the aerosol will condense and flow downward and remain in the containment chamber 21 of the aerosol generating device 20.

[0127] In related technologies, setting a front plug section can effectively reduce the probability of the medium section falling out of the outer packaging layer. However, the front plug section will generate significant suction resistance to the aerosol, reducing the user's suction experience. Therefore, it is desirable to develop an aerosol generating product that can prevent the medium section from falling out and effectively reduce the suction resistance generated by the front plug section on the aerosol.

[0128] The front plug section 12 of this embodiment consists of a wrapping layer 121 and a filling portion. The filling portion is formed by repeatedly bending a layered filling element 122, resulting in a pleated shape. The filling portion is disposed within the wrapping layer 121 to create a channel 123 extending from one end of the front plug section 12 to the other. External airflow can flow through the channel 123 to the medium section 11, thereby reducing the suction resistance of the front plug section 12 on the aerosol extraction and improving the user experience. In other words, after the front plug section 12 of this embodiment is used to generate the aerosol product 10, it can reduce the probability of the medium section 11 falling out of the outer packaging layer 13. At the same time, the front plug section 12 will not generate too much suction resistance on the aerosol extraction. In addition, after the suction is completed, the negative pressure generated during the suction process in the receiving chamber 21 will cause the aerosol to backflow / flow. The pleated filling part has a good adsorption effect and can adsorb the aerosol during the backflow / flow process. This helps to improve the problem of the receiving chamber 21 being contaminated by aerosol and difficult to clean, and also helps to improve the problem of cross-contamination of flavors that may occur when the product 10 is generated by suctioning different flavor aerosols.

[0129] During the suction process, the front plug section 12 can block the ambient air entering the aerosol generating product 10, which is beneficial for heat transfer, increases the heating rate, improves the efficiency of aerosol extraction and flow, and can prevent the aerosol generating matrix from detaching from the receiving chamber 21 of the aerosol generating device 20.

[0130] The materials of the front stopper section 12 include, but are not limited to, paper, non-woven fabric, rubber, polyethylene terephthalate, cellulose acetate, and mineral-containing products.

[0131] It should be noted that the cross-sectional shape of the front plug section 12 is not restricted here.

[0132] In some embodiments, please refer to Figure 5On a plane perpendicular to the axial direction of the front plug section 12, the cross-section of the front plug section 12 is circular.

[0133] In other embodiments, the cross-sectional shape of the front plug section 12 is non-circular in a plane perpendicular to the axial direction of the front plug section 12.

[0134] As can be seen from the foregoing, on a plane perpendicular to the axial direction of the front plug section 12, the wrapping layer 121 is generally annular, while the cross-sectional shape of the front plug section 12 is non-circular. Therefore, after the front plug section 12 and the outer wrapping layer 13 are assembled, the inner sidewall of the outer wrapping layer 13 and the outer sidewall of the wrapping layer 121 can define and form an outer peripheral airway.

[0135] The external airflow can flow to the medium section 11 through the peripheral air passage, thereby reducing the suction resistance of the front plug section 12 on the aerosol, which is beneficial to improving the user experience.

[0136] In addition, the peripheral airway is formed on the periphery of the front plug section 12. After the external airflow flows through the peripheral airway to the medium section 11, it can gradually flow from the periphery of the medium section 11 to the interior. This process can increase the utilization rate of the periphery of the medium section 11, thereby improving the suction performance of the aerosol generating product 10.

[0137] In one embodiment, the cross-sectional shape of the front plug section 12 is corrugated, polygonal, racetrack-shaped, fan-shaped, or elliptical.

[0138] It should be noted that since the filling part is located inside the wrapping layer 121, and the peripheral air passage is formed by the wrapping layer 121 and the outer packaging layer 13, the shape of the cross section of the front plug section 12 can also be considered as the shape of the cross section of the area enclosed by the wrapping layer 121.

[0139] A polygon can have any number of sides and can be a regular polygon or a polygon with sides that are not all equal. For example, it can be a regular heptadecagon, a regular hexagon, or a regular pentagon.

[0140] The term "track shape" refers to a shape similar to an athletic track, consisting of two semicircles of the same radius and two parallel straight edges connected alternately.

[0141] In other words, the cross-section of the front plug section 12 can be any shape other than circular, which facilitates the formation of a peripheral airway between the front plug section 12 and the outer packaging layer 13.

[0142] In one embodiment, the material of the wrapping layer 121 includes at least one of polylactic acid, fiber paper, polyethylene, and polyethylene terephthalate.

[0143] On the one hand, the wrapping layer 121 of this material has a certain toughness, which allows it to be wound around the filling part to obtain the front plug section 12; on the other hand, the wrapping layer 121 of this material also has a certain strength, which can reduce the probability of deformation of the front plug section 12, thus improving the yield of the front plug section 12.

[0144] In one embodiment, the thickness of the wrapping layer 121 ranges from 0.05 mm to 0.5 mm. For example, it is a point value of any one of 0.05 mm, 0.1 mm, 0.15 mm, 0.18 mm, 0.2 mm, 0.25 mm, 0.27 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.46 mm, or 0.5 mm, or a point value between any two of them.

[0145] When the thickness of the wrapping layer 121 is less than 0.05 mm, the wrapping layer 121 is weak due to its low thickness, making it prone to deformation after wrapping the internal filling part. This also leads to weak processing capability of the front plug section 12, resulting in a decrease in yield. When the thickness of the wrapping layer 121 is greater than 0.5 mm, the thickness at the joint after molding is large (the joint is the overlap between the beginning and end of the wrapping layer 121), which results in a poor appearance of the front plug section 12 at the joint. Therefore, by setting the thickness of the wrapping layer 121 to 0.05 mm-0.5 mm, the wrapping layer 121 can have a certain degree of toughness and strength, while also helping to improve the problem of large thickness at the joint.

[0146] The material of filler 122 is not limited. For example, it can be various types of paper.

[0147] In related technologies, the filler 122 is made of polymer materials such as PLA (Polylactic acid), PET (Polyethylene glycol terephthalate), and CA (Cellulose acetate). During use, the front plug section 12 is prone to melting, shrinkage, and collapse when in contact with the heating element 22. This causes blockage of the channel 123 inside the front plug section 12, hindering the airflow from flowing through the channel 123 to the medium section 11 to extract aerosols. As a result, the suction resistance of the aerosol-generated product 10 increases significantly during the suction process, and chemical impurities are generated, affecting the user experience.

[0148] The paper-based filler 122 can operate normally at temperatures below 420°C, while the heating temperature of a typical aerosol generating device 20 is between 200°C and 320°C. Therefore, the filler 122 is less likely to melt or condense when in contact with the heating element 22, reducing the likelihood of blockage in the channel 123 inside the front plug section 12. This avoids a significant increase in suction resistance during the suction process. Furthermore, the paper material does not produce a chemical odor when heated. In addition, the paper-based filler 122 has good adsorption properties, and folding it into a pleated filling section further enhances its adsorption effect, thereby improving its adsorption performance for aerosols during the backflow / reverse flow process.

[0149] In one embodiment, the filler 122 is made of fiber paper.

[0150] The filler 122, made of fiber paper, gives the front plug section 12 better filling strength, which can improve the production qualification rate of the product during subsequent processing. At the same time, it can also improve the connection strength between the front plug section 12 and the medium section 11, and improve the problems of bending and breakage of aerosol generation product 10 caused by insufficient connection strength during use.

[0151] In addition, during the heating process, the fibrous odor produced by the fiber paper can be confined inside the fiber paper, thereby improving the user experience.

[0152] In one embodiment, the basis weight of the fiber paper is in the range of 20 g / m². 2 -140g / m 2 For example, it could be 20g / m³. 2 30g / m 2 40g / m 2 50g / m 2 60g / m 2 70g / m 2 80g / m 2 90g / m 2 100g / m 2 110g / m 2 120g / m 2 130g / m 2 140g / m 2 The point value of any one of them or the point value between any two.

[0153] It should be noted that when the basis weight of the fiber paper is low, its processing performance is low, resulting in a relatively low yield of the front stopper section 12. When the basis weight is high, the paper impurities generated by the filler 122 are heavier during subsequent use, affecting the user's experience.

[0154] In this embodiment, the basis weight of the fiber paper is controlled at 20 g / m². 2 -140g / m 2 Within this range, it is possible to minimize the generation of paper impurities while ensuring the processing performance of the fiber paper. In other words, it can guarantee the yield of the pre-stop section 12 while also taking into account the user experience.

[0155] For example, when there are multiple fillers 122, each filler 122 is bent to form a whole, that is, each layered filler 122 is embossed to form a wrinkled shape, and then multiple embossed fillers 122 are stacked to form a filling part. Alternatively, multiple fillers 122 are first stacked together, and the overall thickness of the stacked fillers 122 is larger than the thickness of a single filler 122, and then the stacked fillers 122 are embossed to form a wrinkled filling part.

[0156] In some embodiments, the porosity of the foreplug section 12 is greater than or equal to 0.1 and less than or equal to 0.8.

[0157] The porosity of the front plug section 12 refers to the ratio of the sum of the cross-sectional areas of the air passages inside the front plug section 12 to the cross-sectional area of ​​the front plug section 12.

[0158] The porosity of the front plug section 12 can be any one of 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8 or any value between two of them.

[0159] The front plug section 12 has air passages of varying shapes (including regular and irregular shapes) in the radial direction of the aerosol-generating article 10.

[0160] It should be noted that when the porosity of the current plug section 12 is too high, the strength of the current plug section 12 is low during use, and the aerosol generating product 10 is prone to deformation and breakage during the suction process, which reduces the user experience; when the porosity of the current plug section 12 is too low, the suction resistance of the current plug section 12 is large during the suction process, which is not conducive to the user's suction of aerosol.

[0161] When the porosity is less than 0.1, the suction resistance of the front plug section 12 is relatively large, which is not conducive to the entry of outside air from the bottom, resulting in a decrease in aerosol extraction efficiency. When the porosity is greater than 0.8, the internal filling value is low, which is not conducive to the absorption of refluxed aerosols, resulting in a decrease in the cleaning ability of the containment chamber 21 and a decrease in the ability to detach the heated aerosol-generated product 10, thus reducing the user experience. In this embodiment, the porosity of the front plug section 12 is controlled within the range of 0.1-0.8. The front plug section 12 has high structural strength and does not generate too much suction resistance.

[0162] In some embodiments, the suction resistance of the front plug section 12 is the same along the direction from the distal lip end of the aerosol generating article 10 to the proximal lip end of the aerosol generating article 10.

[0163] In this embodiment, by setting the suction resistance of the front plug section 12 to be the same, it is beneficial to ensure the consistency of airflow within the front plug section 12, thereby improving the consistency of aerosol flow and enhancing the user's suction experience.

[0164] In some embodiments, the suction resistance of the front plug section 12 is reduced along the direction from the distal lip end to the proximal lip end of the aerosol generating article 10.

[0165] In this embodiment, by reducing the suction resistance of the front plug section 12 along the direction from the distal lip end to the proximal lip end of the aerosol generating article 10, the direction of airflow in the aerosol generating article 10 can be guided, which is beneficial to improving the user's suction experience.

[0166] In some embodiments, the ratio of the length of the medium segment 11 to the length of the foreplug segment 12 is greater than or equal to 1 and less than or equal to 10.

[0167] The ratio of the length of the medium section 11 to the length of the front plug section 12 can be any one of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or any value between the two.

[0168] When the ratio of the length of the medium section 11 to the length of the front stopper section 12 is less than 1.0, the medium section 11 has a lower weight and a lower content of effective substances such as tobacco, which is not conducive to a consistent smoking experience. When the ratio of the length of the medium section 11 to the length of the front stopper section 12 is greater than 10, the suction resistance is higher during smoking, which is not conducive to aerosol extraction during smoking.

[0169] In some embodiments, the length of the front plug section 12 is greater than or equal to 4 mm and less than or equal to 8 mm.

[0170] The length of the front plug section 12 can be any one of 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm or any combination thereof.

[0171] When the length of the front plug section 12 is less than 4mm, it is not conducive to the adsorption of the backflow aerosol after the front plug section 12 has finished suction, which can easily lead to the condensation of aerosol in the aerosol generating device 20. When the length of the front plug section 12 is greater than 8mm, the suction resistance of the front plug section 12 is large, which affects the bottom air intake, thereby reducing the aerosol carrying efficiency and the suction experience. Therefore, it is more appropriate to set the length of the front plug section 12 between 4mm and 8mm.

[0172] In some embodiments, the ratio of the length of the fore-plug section 12 to the length of the aerosol-generating article 10 is greater than or equal to 0.04 and less than or equal to 0.09.

[0173] The ratio of the length of the front plug section 12 to the length of the aerosol-generated product 10 can be any one of 0.04, 0.05, 0.06, 0.07, 0.08, or 0.09, or any value between the two.

[0174] In some embodiments, please refer to Figures 1 to 4 Functional segment 14 includes a second functional segment 142. A first functional segment 141 is disposed at one end of the second functional segment 142 away from the medium segment 11. The second functional segment 142 includes at least one of a flow guiding segment, a cooling segment, a gathering segment, a support segment, or a fragrance carrying segment.

[0175] Here, the second functional section 142 can be one of the following: a flow guiding section, a cooling section, a gathering section, a supporting section, or a fragrance carrying section; or it can be multiple of the following: a flow guiding section, a cooling section, a gathering section, a supporting section, or a fragrance carrying section.

[0176] For example, the fragrance-carrying segment is loaded with fragrance substances.

[0177] After the aerosol product 10 is extracted, the aerosol passes through the fragrance-carrying section. The heat inherent in the aerosol itself exchanges heat with the aroma-producing components in the fragrance-carrying section, causing the aerosol temperature to drop. Furthermore, this releases the aroma-producing components and allows them to mix with the aerosol, improving the richness and consistency of the aroma within the aerosol. Simultaneously, in addition to its high fragrance-carrying capacity, the fragrance-carrying section also serves a cooling function.

[0178] The term "fragrance-carrying segment" refers to the ability of fragrance substances to penetrate, be absorbed, or adhere to the interior of the fragrance-carrying segment.

[0179] It should be noted that the specific components of the flavoring are not limited here.

[0180] For example, the fragrance ingredient may include monomeric fragrance substances, such as one or more combinations of megastigmatrienone, neophytadiene, geraniol, nerol, etc.

[0181] For example, this can also be achieved by embedding a capsule containing the fragrance substance in the fragrance-carrying segment.

[0182] In some embodiments, please refer to Figures 1 to 3 The ratio of the length of the filter section to the length of the aerosol-generating product 10 is greater than or equal to 0.06 and less than or equal to 0.3.

[0183] Here, the ratio of the length of the filter section to the length of the aerosol generating product 10 can be any one of 0.06, 0.08, 0.1, 0.15, 0.2, 0.25, 0.3 or any value between the two.

[0184] For example, the length of the filter section is greater than or equal to 4 mm and less than or equal to 15 mm.

[0185] Here, the length of the filter segment can be any one of 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, or 15mm, or any combination thereof.

[0186] It can be understood that, given a fixed length of the aerosol generating product 10, the longer the filter section, the greater the ratio of the length of the filter section to the length of the aerosol generating product 10; conversely, the shorter the filter section, the smaller the ratio of the length of the filter section to the length of the aerosol generating product 10.

[0187] When the ratio of the length of the filter section to the length of the aerosol generating product 10 is less than 0.06, the filter section is too short, which is not conducive to the screening of large molecules in the aerosol, and easily leads to a rough aroma and a decline in aroma quality. When the ratio of the length of the filter section to the length of the aerosol generating product 10 is greater than 0.3, the filter section is too long, which increases the filtration of aerosols, leading to an increase in the interception rate, which in turn leads to a decrease in transmission efficiency, resulting in a decrease in aerosol utilization and a reduction in the user experience.

[0188] In this embodiment, by setting the ratio of the length of the filter section to the length of the aerosol-generated product 10 to 0.06-0.30, it is beneficial to screen macromolecules in the aerosol without affecting the aerosol utilization rate, thereby improving the aroma quality.

[0189] In some embodiments, please refer to Figures 1 to 4 The interior of the second functional section 142 has a first air intake passage 1421 extending in a first direction. The second functional section 142 has a second air intake passage 1422 passing through the side wall of the first air intake passage 1421. The first air intake passage 1421 communicates with the outside of the functional section 14 through the second air intake passage 1422.

[0190] Here, the second functional section 142 forms a second air intake channel 1422 that passes through the side wall of the first air intake channel 1421. That is, the second air intake channel 1422 passes through the side wall of the first air intake channel 1421 and is connected to the first air intake channel 1421.

[0191] In this embodiment, the first air intake channel 1421 is connected to the outside of the functional section 14 through the second air intake channel 1422. External air can enter the first air intake channel 1421 through the second air intake channel 1422, which is beneficial to cooling the aerosol in the first air intake channel 1421, thereby further improving the cooling effect of the cooling section.

[0192] By adding a lateral air intake channel (i.e., the second air intake channel 1422), 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.

[0193] In some embodiments, please refer to Figures 1 to 4 The distance between the second air intake channel 1422 and the near lip end of the second functional section 142 is greater than or equal to 4 mm and less than or equal to 20 mm.

[0194] The distance between the second air intake channel 1422 and the near-lip end of the second functional section 142 can be any one of 4mm, 5mm, 6mm, 7mm, 8mm, 10mm, 12mm, 15mm, 18mm, or 20mm, or any value between two of them.

[0195] When the distance between the second air intake channel 1422 and the near-lip end of the second functional section 142 is less than 4 mm, the mixing area provided by the incoming outside air is small, which is not conducive to the expression of aerosol aroma. When the distance between the second air intake channel 1422 and the near-lip end of the second functional section 142 is greater than 20 mm, the aerosol is easily mixed with the outside air in advance, resulting in condensation of the aerosol during transmission, throttling, and a decrease in transmission efficiency. In other words, by setting the distance between the second air intake channel 1422 and the near-lip end of the second functional section 142 to be greater than or equal to 4 mm, it is beneficial for the air entering from the second air intake channel 1422 to be fully mixed with the aerosol in the first air intake channel 1421, thereby improving the cooling effect of the cooling section. On the other hand, setting the distance between the second air intake channel 1422 and the near-lip end of the second functional section 142 to be less than or equal to 20 mm is beneficial for improving the transmission efficiency of the aerosol and mitigating condensation during transmission.

[0196] In some embodiments, please refer to Figures 1 to 4 The ratio of the air intake volume of the second air intake channel 1422 to the total air intake volume of the aerosol generating product 10 is greater than or equal to 0.2 and less than or equal to 0.6.

[0197] The ratio of the air intake volume of the second air intake channel 1422 to the total air intake volume of the aerosol generating product 10 can be any one of 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6 or any value between the two.

[0198] Here, the second functional section 142 is formed with a second air intake passage 1422 passing through the side wall of the first air intake passage 1421, so that the second functional section 142 has a ventilation level of 20% to 60%.

[0199] Here, the ventilation level can also be described as the side-flow ventilation rate, which is the combined ratio of the side airflow (i.e., the airflow through the second air intake channel 1422) to the side airflow and the bottom airflow (i.e., the airflow through the distal lip of the aerosol-generated product 10).

[0200] When the ratio of the air intake volume of the second air intake channel 1422 to the total air intake volume of the aerosol generating product 10 is less than or equal to 0.2, the proportion of outside air entering the aerosol generating product 10 through the second air intake channel 1422 is relatively small, making it difficult to cool the high-temperature aerosol generated in the medium section 11, which can easily lead to the aerosol overheating phenomenon. When the ratio of the air intake volume of the second air intake channel 1422 to the total air intake volume of the aerosol generating product 10 is greater than or equal to 0.6, the proportion of outside air entering the aerosol generating product 10 through the second air intake channel 1422 is relatively small, making it difficult to cool the aerosol generated in the medium section 11, which can easily lead to the aerosol overheating phenomenon. The high proportion of air leads to excessive dilution of the aerosol produced in the medium section 11, resulting in reduced extraction efficiency and a poor suction experience. Therefore, the ratio of the air intake volume of the second air intake channel 1422 to the total air intake volume of the aerosol-generating product 10 is greater than or equal to 0.2 and less than or equal to 0.6. This facilitates thorough mixing of the air entering from the second air intake channel 1422 with the aerosol in the first air intake channel 1421, thereby improving the cooling effect of the cooling section, increasing the aerosol transmission efficiency, and mitigating condensation during transmission.

[0201] In some embodiments, please refer to Figures 1 to 4 The ratio of the sum of the cross-sectional areas of all the second intake passages 1422 to the side area of ​​the second functional section 142 is greater than or equal to 0.0001 and less than or equal to 0.02.

[0202] The ratio of the sum of the cross-sectional areas of all the second intake passages 1422 to the side area of ​​the second functional section 142 can be any one of 0.0001, 0.0003, 0.0008, 0.001, 0.002, 0.003, 0.005, 0.006, 0.007, 0.008, 0.009, 0.01, 0.015, 0.02 or any value between the two.

[0203] When the ratio of the sum of the cross-sectional areas of all the second air intake channels 1422 to the side area of ​​the second functional section 142 is less than 0.0001, the proportion of outside air entering the aerosol generating product 10 from the second air intake channels 1422 is relatively small, and the high-temperature aerosol generated by the medium section 11 is not easily cooled, which can easily lead to the aerosol getting hot. When the ratio of the sum of the cross-sectional areas of all the second air intake channels 1422 to the side area of ​​the second functional section 142 is greater than 0.02, the proportion of outside air entering the aerosol generating product 10 from the second air intake channels 1422 is relatively high, which can lead to the aerosol generated by the medium section 11 being diluted too much and the extraction efficiency being reduced, which is not conducive to the suction experience.

[0204] In some embodiments, please refer to Figures 1 to 4 The length of the second functional segment 142 is greater than or equal to 16mm and less than or equal to 36mm.

[0205] The length of the second functional segment 142 can be any one of 16mm, 18mm, 20mm, 25mm, 26mm, 27mm, 30mm, 32mm, 33mm, 35mm, or 36mm, or any combination thereof.

[0206] For example, the ratio of the length of the second functional segment 142 to the length of the aerosol-generating article 10 is greater than or equal to 0.2 and less than or equal to 0.6.

[0207] It can be understood that, given a fixed length of the aerosol-generating product 10, the longer the second functional segment 142 is, the greater the ratio of the length of the second functional segment 142 to the length of the aerosol-generating product 10; conversely, the shorter the length of the second functional segment 142 is, the smaller the ratio of the length of the second functional segment 142 to the length of the aerosol-generating product 10.

[0208] When the ratio of the length of the second functional section 142 to the length of the aerosol generating product 10 is less than 0.2, the length of the second functional section 142 is too short, which is not conducive to cooling the aerosol generated by the medium section 11, resulting in excessively high flue gas temperature during the suction process. When the ratio of the length of the second functional section 142 to the length of the aerosol generating product 10 is greater than 0.6, the length of the second functional section 142 is too long, and the aerosol is easily condensed and intercepted during the transmission process, resulting in reduced transmission efficiency, which in turn reduces the aerosol utilization rate and is not conducive to improving the user experience.

[0209] In this embodiment, by setting the ratio of the length of the second functional segment 142 to the length of the aerosol generating article 10 to be greater than or equal to 0.2 and less than or equal to 0.6, it is beneficial to improve the cooling effect of the second functional segment 142 on the aerosol, while also improving the aerosol transmission efficiency and improving the condensation situation during transmission.

[0210] In some embodiments, please refer to Figures 1 to 5 Functional segment 14 and medium segment 11 are cylinders and are coaxially arranged, with the first direction being the axial direction of functional segment 14 and medium segment 11.

[0211] By setting both functional segment 14 and medium segment 11 as cylinders and arranging them sequentially along their axial directions, the structure of the aerosol generating product 10 can be made more compact, improving the user experience.

[0212] In some embodiments, please refer to Figure 1 The aerosol generating device 20 is provided with a receiving chamber 21 and a third air inlet channel 24 connected to the receiving chamber 21. The receiving chamber 21 is used to contain at least a portion of the aerosol generated product 10. The third air inlet channel 24 is located at the bottom of the receiving chamber 21. The ratio of the air intake of the third air inlet channel 24 to the total air intake of the aerosol generating system 100 is greater than or equal to 0.4 and less than or equal to 0.8.

[0213] The ratio of the air intake volume of the third air intake channel 24 to the total air intake volume of the aerosol generation system 100 can be any one of 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8 or any value between the two.

[0214] When the ratio of the air intake volume of the third air intake channel 24 to the total air intake volume of the aerosol generation system 100 is greater than 0.8, the aerosol generated by the medium section 11 is not easily cooled, which can easily cause the flue gas to become hot. When the ratio of the air intake volume of the third air intake channel 24 to the total air intake volume of the aerosol generation system 100 is less than 0.4, the aerosol extraction efficiency generated at the bottom of the medium section 11 is low, resulting in a low aerosol utilization rate.

[0215] For example, the ratio of the air intake volume of the second air intake channel 1422 to the air intake volume of the third air intake channel 24 is 10:90 to 50:40.

[0216] When the ratio of the air intake volume of the second air intake channel 1422 to the air intake volume of the third air intake channel 24 is less than 10:90, the aerosol generated in the medium section 11 is not easily cooled, which can easily cause the flue gas to become hot. When the ratio of the air intake volume of the second air intake channel 1422 to the air intake volume of the third air intake channel 24 is greater than 50:40, the aerosol extraction efficiency generated at the bottom of the medium section 11 is low, resulting in low aerosol utilization.
