[0047] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed description in the specific implementation methods should be understood as an explanation of this application and should not be regarded as an improper restriction on this application.

[0048] In the description of the embodiments of the present application, the terms "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the embodiments of the present application.

[0049] An embodiment of the present application provides an aerosol-generating product 1 , as shown in FIG. 1 to FIG. 12 , which includes a wrapping layer 10 , a dielectric segment 11 , a functional segment 12 and a stopper 13 .

[0050] An embodiment of the present application provides an aerosol-generating system, comprising an aerosol-generating device and an aerosol-generating article 1 according to any embodiment of the present application. The aerosol-generating article 1 can be plugged into and unplugged from the aerosol-generating device. The aerosol-generating device includes a heater for heating a dielectric segment 11 to generate an aerosol. The aerosol can be discharged from the aerosol-generating device for inhalation by a user.

[0051] The medium segment 11 is used to generate aerosol, that is, at least a portion of the medium segment 11 is composed of an aerosol-generating substrate, so that the medium segment 11 can generate aerosol for use by a user.

[0052] The specific form of the heating element is not limited, and can be a resistive heating film, an electromagnetic induction heating element, an infrared heating coating, a laser heating element, etc., and is not limited here.

[0053] The wrapping layer 10 wraps around the circumferential outer surface of at least a portion of the stopper 13 , the medium segment 11 , and at least a portion of the functional segment 12 .

[0054] Specifically, during the manufacturing process, the wrapping layer 10 can be directly wrapped on the circumferential outer surface of at least a portion of the stopper 13, the dielectric segment 11, and at least a portion of the functional segment 12 through a rolling process to integrate the stopper 13, the dielectric segment 11, and the functional segment 12 together, thereby improving the overall structural strength of the aerosol generating product 1, reducing the probability of failure caused by separation of the various parts of the aerosol generating product 1 during transportation and use, and increasing the reliability of the aerosol generating product 1.

[0055] It is understood that the material of the wrapping layer 10 has a certain structural strength to reduce the probability of deformation caused by airflow pressure during use of the aerosol generating article 1. The wrapping layer 10 can be an integral structure or a combined structure.

[0056] The specific material of the wrapping layer 10 is not limited, such as one or more combinations of fiber paper, metal foil, metal foil composite fiber paper, PE (Polyethylene), polyethylene composite fiber paper, PBAT (Poly (butylene adipate-co-terephthalate, polybutylene terephthalate)), etc.

[0057] The dielectric segment 11 is an integral structure and is disposed between the functional segment 12 and the stopper 13 .

[0058] That is to say, the medium segment 11 is an integrally formed structure, for example, an integrally formed extrusion molding, an integrally formed injection molding, an integrally formed die-casting molding, etc.

[0059] The portion of the wrapping layer 10 that protrudes from the medium segment 11 away from the stopper 13 along the length direction is the first wrapping segment 101. The functional segment 12 is at least partially arranged in the first wrapping segment 101. The first wrapping segment 101 and / or the functional segment 12 define the first air inlet 10a.

[0060] There are many situations in which the first wrapping segment 101 and / or the functional segment 12 define the first air inlet 10a. The first wrapping segment 101 may define the first air inlet 10a, the functional segment 12 may define the first air inlet 10a, or the first wrapping segment 101 and the functional segment 12 may jointly define the first air inlet 10a.

[0061] That is to say, during use, negative pressure is generated by suction, and the air in the external environment enters the aerosol generating product 1 from the first air inlet 10a and moves toward the medium segment 11, thereby driving the aerosol generated by the atomization of the medium segment 11 to flow out of the aerosol generating product 1 for the user to inhale.

[0062] It can be understood that in some embodiments, the wrapping layer 10 further includes a second wrapping segment 102 and a third wrapping segment 103 along the length direction, and the first wrapping segment 101, the second wrapping segment 102 and the third wrapping segment 103 are connected in sequence along the length direction, the second wrapping segment 102 is wrapped around the circumferential outer surface of the medium segment 11, and the third wrapping segment 103 is wrapped around the circumferential outer surface of at least a portion of the stop member 13. The first wrapping segment 101, the second wrapping segment 102 and the third wrapping segment 103 together constitute the wrapping layer 10, and the first wrapping segment 101, the second wrapping segment 102 and the third wrapping segment 103 can be an integrally molded structure, that is, the wrapping layer 10 is an integral structure, and the first wrapping segment 101, the second wrapping segment 102 and the third wrapping segment 103 can also be independent components, which are assembled to form the wrapping layer 10, that is, the wrapping layer 10 is a combined structure.

[0063] It should be noted that when the first wrapping segment 101 wraps the entire circumferential outer surface of the functional segment 12, the user can directly hold the first wrapping segment 101 in the mouth to use the aerosol. When the first wrapping segment 101 wraps part of the circumferential outer surface of the filter segment 12, the user can directly hold the functional segment 12 exposed outside the first wrapping segment 101 in the mouth to inhale the aerosol. Of course, the user can also install a nozzle on the outer surface of the functional segment 12 and inhale the aerosol through the nozzle.

[0064] The stopper 13 is used to cooperate with the end of the medium segment 11 away from the functional segment 12, that is, the stopper 13 can abut against the end of the medium segment 11 away from the functional segment 12 to inhibit the movement of the medium segment 11 in the direction away from the functional segment 12, so that the medium segment 11 will not fall out of the wrapping layer 10.

[0065] It should be noted that the stopper 13 and the end of the dielectric segment 11 away from the functional segment 12 may be cooperated in such a way that the dielectric segment 11 and the stopper 13 are spaced apart, and after the stopper 13 moves a certain distance in the direction away from the functional segment 12, the stopper 13 abuts against the end of the dielectric segment 11 away from the functional segment 12. Alternatively, the stopper 13 and the end of the dielectric segment 11 away from the functional segment 12 may always remain in abutment with each other.

[0066] It can be understood that the cooperation method between the stopper 13 and the wrapping layer 10 is not limited. For example, in some embodiments, the stopper 13 can be cooperated with the wrapping layer 10 by interference fit; in other embodiments, the stopper 13 can also be cooperated with the wrapping layer 10 by bonding, snapping, etc. In this way, the stopper 13 can be better fixed on the wrapping layer 10, which is convenient for stop cooperation with the medium segment 11.

[0067] It is understood that a certain force exists between the dielectric segment 11 and the inner wall of the wrapping layer 10 to inhibit the dielectric segment 11 from moving. For example, the outer circumferential surface of the dielectric segment 11 is in contact with the inner wall of the wrapping layer 10, and the friction between the outer circumferential surface of the dielectric segment 11 and the inner wall of the wrapping layer 10 maintains the dielectric segment 11 in place. The outer circumferential surface of the dielectric segment 11 and the inner wall of the wrapping layer 10 form an interference fit or a transition fit, which creates compression between the two and increases friction.

[0068] In the related art, the medium segment is easily moved due to the shaking of the aerosol generating product during transportation and use. In addition, the medium segment is easily shrunk and deformed during the heating process, thereby falling off from the wrapping layer under the action of gravity, affecting the structural reliability of the aerosol generating product.

[0069] Therefore, in the aerosol generating product 1 provided in the embodiment of the present application, air from the external environment enters from the first air inlet 10a instead of directly entering through the medium segment 11, thereby improving the temperature consistency of the medium segment 11 during atomization, and reducing the probability that the aerosol composition generated will be different due to large changes in the atomization temperature of the medium segment 11 caused by the air from the external environment entering directly from the medium segment 11. The medium segment 11 cooperates with the stopper 13 to constrain the range of movement of the medium segment 11 in the wrapping layer 10, so that the position of the medium segment 11 in the wrapping layer 10 is stable, reducing the probability of the medium segment 11 falling out of the wrapping layer 10 due to the shaking of the aerosol generating product 1 during transportation and use; at the same time, it also reduces the probability of the medium segment 11 shrinking and deforming due to heating and falling from the wrapping layer 10 due to factors such as gravity; in addition, the stopper 13 can also adjust the suction resistance, reduce the probability of condensate generated after the aerosol condenses flowing out of the aerosol generating product 1, and enhance the user experience.

[0070] The specific components of the aerosol-generating matrix are not limited here. For example, the aerosol-generating matrix may include plant components, auxiliary components, smoke-generating components, adhesive components, etc.

[0071] In some embodiments, the plant component is one or more combinations of powders formed from crushed tobacco leaves, tobacco leaf fragments, tobacco stems, tobacco dust, and flavorful plants. The plant component is the core source of the flavor of the product. Endogenous substances in the plant component, such as nicotine, enter the human bloodstream through aerosolization, promoting dopamine production in the pituitary gland, thereby achieving a sense of physiological satisfaction.

[0072] In some embodiments, the auxiliary ingredient may be one or more combinations of inorganic fillers, lubricants, and emulsifiers. Inorganic fillers include one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. Inorganic fillers can provide skeletal support for the plant component and, because they have micropores, can increase the porosity of the wall material after the plant component is formed, thereby improving the aerosol release rate.

[0073] Lubricants include one or more of candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. Lubricants can increase particle flowability, reduce friction between particles, and achieve a more uniform particle density. They can also reduce mold pressure and reduce mold wear.

[0074] Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers (also known as surfactants) reduce the interfacial tension between water-soluble and water-insoluble components in a mixed system and form a strong film on the surface of the droplets. Alternatively, due to the charge imparted by the emulsifier, an electrical double layer is formed on the droplet surface, preventing the droplets from agglomerating and maintaining a uniform emulsion. Emulsifying and homogenizing two immiscible components can improve the consistency of product quality.

[0075] The function of the smoke-generating agent component is to generate a large amount of vapor when heated, thereby increasing the amount of smoke produced by the smoking article. In one embodiment, the smoke-generating agent may include, for example, a monohydric alcohol (such as menthol); a polyhydric alcohol (such as propylene glycol, triethylene glycol, 1,3-butylene glycol, and glycerol); an ester of a polyhydric alcohol (such as glyceryl monoacetate, glyceryl diacetate, or glyceryl triacetate); a monocarboxylic acid; a polycarboxylic acid (such as lauric acid, myristic acid), or an aliphatic ester of a polycarboxylic acid (such as dimethyl dodecanedioate, dimethyl tetradecanedioate, erythritol, 1,3-butylene glycol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, triactin, meso-erythritol, a mixture of diacetyl glycerides, diethyl suberate, triethyl citrate, benzyl benzoate, benzyl phenylacetate, ethyl vanillate, tributyrin, and lauryl acetate).

[0076] In some embodiments, the adhesive component is a natural plant-derived, non-ionically modified viscous polysaccharide, including one or more combinations of tamarind polysaccharide, pullulan, seaweed polysaccharide, locust bean gum, guar gum, and xyloglucan. The adhesive wetting and intimately contacting the product's component materials creates intermolecular attraction, thereby bonding the powders and liquids of the component materials. The use of a natural plant-derived, non-ionic adhesive can prevent the release of harmful substances such as methanol, formaldehyde, and acrolein caused by colloid modification, thereby improving the safety of the product.

[0077] In some embodiments, referring to Figures 1 to 9, the functional section 12 has an air inlet channel 12a and an air outlet channel 12b. One end of the air inlet channel 12a is connected to the first air inlet 10a, and the other end is connected to the air outlet channel 12a. The air outlet channel 12a guides the aerosol out of the aerosol generating product 1.

[0078] Specifically, when inhalation generates negative pressure, air from the external environment enters the air inlet channel 12a through the first air inlet 10a. The air in the air inlet channel 12a guides the air from the external environment toward the dielectric segment 11. After entraining the aerosol generated by atomization in the dielectric segment 11, the air in the external environment flows out of the aerosol-generating article 1 under the guidance of the air outlet channel 12a, and is inhaled by the user. The functional segment 12 not only guides the air from the external environment toward the dielectric segment 11, but also directs the aerosol out of the aerosol-generating article 1 for inhalation by the user. This makes the aerosol-generating article 1 more compact and highly reliable.

[0079] In some embodiments, referring to FIG. 2 , FIG. 3 , FIG. 5 , and FIG. 7 to FIG. 12 , the medium segment 11 has at least one airway hole 11 a , and the airway hole 11 a passes through at least one end of the medium segment 11 close to the functional segment 12 along the length direction.

[0080] In this way, the aerosol generated by the heated atomization of the medium segment 11 can be directly released from the airway hole 11a and flow out toward the air outlet channel 12b. The aerosol has sufficient release space, thereby improving the aerosol extraction rate.

[0081] It should be noted that there are multiple situations in which the airway hole 11a passes through at least one end of the medium segment 11 close to the functional segment 12 along the length direction.

[0082] In the first type, the airway hole 11a only passes through one end of the medium segment 11 close to the functional segment 12, that is, the end of the airway hole 11a close to the functional segment 12 is open, and the end away from the functional segment 12 is closed, and the airway hole 11a is formed as a blind hole.

[0083] The second type is that the airway hole 11a passes through both ends of the medium segment 11 along the length direction, that is, the end of the airway hole 11a close to the functional segment 12 is in an open state, and the end away from the functional segment 12 is also in an open state.

[0084] The number of the airway holes 11a is not limited and can be one or two or more.

[0085] It should be noted that in the embodiments of the present application, the length direction does not specifically refer to the direction in which the outer contour of the dielectric segment 11 is longest. The arrangement direction of the stopper 13 and the functional segment 12 is consistent with the length direction; the direction in which the aerosol-generating article 1 is inserted into the aerosol-generating device and the direction in which the aerosol-generating article 1 is removed from the aerosol-generating device are both parallel to the length direction. The length of the dielectric segment 11 may be longer, shorter, or the same as the length in other directions.

[0086] For example, in some examples, when the dielectric segment 11 is cylindrical, the length direction is the axial direction of the dielectric segment 11. It should be noted that even when the axial dimension of the dielectric segment 11 is smaller than its diameter, the length direction of the dielectric segment 11 is still the axial direction.

[0087] In other examples, when the outer contour of the medium segment 11 is a rectangular parallelepiped, the length direction is still the direction defined above, that is, the arrangement direction of the stopper 13 and the functional segment 12; or, in the direction of taking and placing the aerosol generating product 1, the length direction of the medium segment 11 can be any direction of the length, width, or height of the rectangular parallelepiped.

[0088] It is understood that the medium segment 11 is formed with micropores, which are interconnected to form micro-airways. Some of the micropores are connected to the airway holes 11a, while other micro-airways directly penetrate the air inlet and outlet ends of the medium segment 11. This allows aerosol to be discharged from the medium segment 11 in a variety of ways. For example, the aerosol generated by the medium segment 11 after heating can directly enter the airway holes 11a and be entrained by the air in the external environment and discharged; alternatively, the air in the external environment directly enters the micro-airway and discharges the aerosol entrained in the micro-airway; or alternatively, the aerosol enters the airway holes 11a from the micro-airway.

[0089] It is understood that the micropores may be interconnected, with some micropores interconnected and others disconnected, or all micropores interconnected. For example, in an embodiment in which the medium segment 11 is a particle assembly, the gaps between the particles constitute the micropores, wherein the size of the micropores is determined by the gaps between the particles in the medium segment 11.

[0090] It should be noted that the airway holes 11 a are holes in a macroscopic sense and can be identified by the naked eye, while the micropores are holes in a peripheral sense and cannot be identified by the naked eye.

[0091] The airway holes 11a and micropores increase the surface area of ​​the dielectric segment 11, facilitating heat transfer and improving heating efficiency. The aerosol-generating matrix within the dielectric segment 11 releases aerosol upon heating. Under the negative pressure generated by the user's inhalation, the aerosol is transported to the functional segment 12. The airway holes 11a and micropores reduce the user's inhalation resistance, enhancing the user experience and reducing the adverse effects of condensed aerosol remaining in the dielectric segment 11, which could affect airflow.

[0092] In some embodiments, referring to FIG. 1 to FIG. 3 and FIG. 6 to FIG. 12 , the first wrapping segment 101 is provided with a first air inlet 10 a , and the first air inlet 10 a passes through a side wall of the first wrapping segment 101 .

[0093] In this embodiment, the first air inlet 10a is formed by processing the first wrapping segment 101, and the air in the external environment enters the air inlet channel 12a of the functional segment 12 from the side of the first wrapping segment 101, which facilitates the extraction of aerosol.

[0094] The number of the first air inlet 10a may be one, or two or more.

[0095] It should be noted that if there are too many first air inlets, the air intake will be too much, the suction resistance will be small, and the aerosol content inhaled will be small. If there are too few first air inlets, the air intake will be too little, the suction resistance will be large, and the aerosol content inhaled will be small, affecting the user experience.

[0096] In some embodiments, the number of the first air inlets 10a is 4-30, for example, 4, 5, 7, 8, 10, 13, 17, 20, 25, 28, 30, etc.

[0097] In this embodiment, the number of the first air inlets 10a is appropriate, neither too many nor too few, and the suction resistance is appropriate, so that the aerosol content inhaled by the user is appropriate, thereby improving the user experience.

[0098] In other embodiments, please refer to Figures 4 and 5, a groove 12c is provided on the circumferential surface of the functional segment 12, and the groove 12c passes through at least one end of the functional segment 12 close to the medium segment 11, and the end of the functional segment 12 away from the medium segment 11 passes through the first wrapping segment 101, and the gap between the end of the first wrapping segment 101 and the functional segment 12 defines the first air inlet 10a, and the inner wall of the first wrapping segment 101 and the groove wall of the groove 12c define the air inlet channel 12a.

[0099] In this embodiment, the first air inlet 10a is defined by the clearance between the first wrapping segment 101 and the functional segment 12. This eliminates the need for additional processing of the first wrapping segment 101, reduces the manufacturing requirements for the wrapping layer 10, and simplifies the manufacturing process of the aerosol-generating article 1. Air from the external environment enters through the clearance between the end of the first wrapping segment 101 and the functional segment 12, driving the aerosol out through the air outlet channel 12b.

[0100] It can be understood that in this embodiment, the end of the functional segment 12 away from the medium segment 11 passes through the wrapping layer 10 and is exposed outside the wrapping layer 10. When inhaling, the user can directly hold the part of the functional segment 12 exposed outside the wrapping layer 10 in the mouth to inhale the aerosol, which is more convenient to inhale the aerosol and gives the user a better experience.

[0101] Of course, in some examples, the first air inlet 10a is provided at the position of the first wrapping segment 101 corresponding to the groove 12c. In this embodiment, the first wrapping segment 101 is wrapped around the entire circumferential outer surface of the functional segment 12, and the first air inlet 10a can pass through the side wall of the groove 12c corresponding to the first wrapping segment 101. The air in the external environment can enter the groove 12c through the first air inlet 10a and then enter the medium segment 11, carrying the aerosol and flowing out of the aerosol generating product 1 for the user to inhale.

[0102] It can be understood that, in this embodiment, the groove 12c at least passes through the end of the functional segment 12 close to the dielectric segment 11. Alternatively, the groove 12c only passes through the end of the functional segment 12 close to the dielectric segment 11, or the groove 12c passes through both the end of the functional segment 12 close to the dielectric segment 11 and the end of the functional segment away from the dielectric segment 11, that is, the groove 12c passes through both ends of the functional segment 12 along the length direction.

[0103] 5 , the groove 12 c at least partially overlaps with the airway hole 11 a . Thus, air from the external environment can quickly flow into the airway hole 11 a after entering through the first air inlet 10 a , thereby improving the aerosol extraction efficiency.

[0104] In some embodiments, as shown in Figures 2, 3, and 5, the functional segment 12 has one or more central air channels 12d extending longitudinally through the functional segment 12. These central air channels 12d at least partially overlap with the airway apertures 11a. In other words, the central air channels 12d at least partially abut the airway apertures 11a, enabling rapid aerosol extraction, increasing extraction efficiency, and enhancing the user experience.

[0105] In some embodiments, please refer to Figures 6 to 12, the functional section 12 is a hollow tubular structure having an inner wall surface 12f and an outer wall surface 12e, the inner wall surface 12f encloses a hollow space 12g, and the side wall of the functional section 12 is provided with a second air inlet 12h, the second air inlet 12h at least passes through the outer wall surface 12e, and the second air inlet 12h is connected to the first air inlet 10a.

[0106] That is to say, the air in the external environment can directly enter the functional section 12 through the second air inlet 12h after passing through the first air inlet 10a, extract the aerosol, and drive the aerosol to flow out from the hollow space 12g. The hollow space 12g can extend the flow path and flow area of ​​the aerosol, thereby slowing down the flow rate of the aerosol, thereby achieving a cooling effect, making the use temperature of the aerosol more suitable.

[0107] The second air inlet 12h at least penetrates the outer wall surface 12e. The second air inlet 12h may penetrate only the outer wall surface 12e, or may penetrate both the outer wall surface 12e and the inner wall surface 12f.

[0108] In some embodiments, referring to FIG. 8 , the structure between the inner wall surface 12 f and the outer wall surface 12 e is a solid structure, and the second air inlet 12 h passes through the inner wall surface 12 f and the outer wall surface 12 e.

[0109] It should be noted that the solid structure can be a solid acetate fiber structure, that is, the structure between the inner wall surface 12f and the outer wall surface 12e of the functional segment 12 is a structure filled with acetate fiber bundles. At this time, the functional segment 12 is a hollow acetate fiber structure, and there are gaps between the acetate fiber bundles to form an air flow channel. The air in the external environment can enter the hollow space 12g through the second air inlet 12h, move toward the medium segment 11 to entrain the aerosol and flow out of the functional segment 12. The air in the external environment can also flow directly from the hollow space 12g to the functional segment 12 through the second air inlet 12h and entrain the aerosol in the air flow channel.

[0110] The solid structure can also be a tubular structure without an internal airflow channel, such as a paper tube or aluminum foil tube. Specifically, the functional segment 12 is a hollow paper tube or aluminum foil tube structure. Air from the external environment enters the hollow space 12g through the second air inlet 12h, flows toward the dielectric segment 11, and carries the aerosol toward the functional segment 12. Hollow paper tube and aluminum foil tube structures are lightweight, reducing the overall weight of the aerosol-generating article 1 and utilizing their hollow area to lower the aerosol temperature. Furthermore, these hollow paper tube and aluminum foil tube structures exhibit excellent heat resistance, resist deformation under heat, and maintain their shape after heat conduction, thereby increasing the structural stability of the aerosol-generating article 1. For example, referring to FIG. 8 , the functional segment 12 is a hollow paper tube structure.

[0111] Of course, the functional segment 12 may also be a hollow silica gel structure, a hollow PET (polyethylene glycol terephthalate) structure, etc., which is not limited here.

[0112] In this embodiment, the second air inlet 12h penetrates both the outer wall 12e and the inner wall 12f. Air in the external environment enters through the first air inlet 10a and the second air inlet 12h to extract aerosol and flows out from the hollow space 12g.

[0113] It can be understood that acetate fiber refers to acetate fiber, also known as cellulose acetate or cellulose acetate, which is a chemically modified polymer compound obtained by esterifying the hydroxyl groups in cellulose molecules with acetate, including diacetate fiber and triacetate fiber, which has good acid and alkali resistance and organic solvent resistance.

[0114] In some embodiments, referring to FIG. 9 , a groove 12i is provided between the inner wall 12f and the outer wall 12e and passes through at least one end of the functional section 12 along the length direction, and the second air inlet 12h is connected to the groove 12i.

[0115] It is understood that in this embodiment, the functional section 12 can be a hollow corrugated tube structure, a porous structure, etc. For example, referring to FIG6 , the functional section 12 is a hollow corrugated tube structure, and the cross section of the area between the inner wall and the outer wall of the hollow corrugated tube is generally wavy.

[0116] The communication method between the second air inlet 12h and the groove 12i is not limited.

[0117] For example, in some embodiments, please refer to Figure 9, the second air inlet 12h only passes through the outer wall 12e, that is, the first air inlet 12h does not pass through the inner wall 12f, and the air in the external environment enters the groove 12i through the first air inlet 10a and the second air inlet 12h to enter the medium section 11, and the extracted aerosol flows out from the hollow space 12g. In this embodiment, the air in the external environment has only one air flow channel to extract the aerosol, which facilitates the consistency of aerosol extraction. In addition, it is also convenient to cool the aerosol.

[0118] In some other embodiments, referring to FIG. 7 , the second air inlet 12 h passes through the groove 12 i and penetrates the inner wall surface 12 f.

[0119] In this embodiment, the second air inlet 12h passes through both the outer wall 12e and the inner wall 12f. At this time, the air in the external environment can enter the hollow space 12g through the first air inlet 10a and the second air inlet 12h to extract aerosols, or enter the groove 12i through the first air inlet 10a and the second air inlet 12h to extract aerosols and flow out from the air outlet channel 12b. That is to say, in this embodiment, the air in the external environment can have two air flow channels. In this way, more aerosols can be extracted per unit time, which is convenient for improving the aerosol extraction efficiency.

[0120] It should be noted that the number of the second air inlets 12h is not limited, and can be one, or two or more.

[0121] In some examples, aroma substances are provided in the functional section 12, so as to enrich the flavor of the aerosol and enhance the user experience.

[0122] In some embodiments, as shown in FIG3 , the functional segment 12 and the stopper 13 have the same structure and are symmetrically arranged with respect to the dielectric segment 11. This allows the user to assemble and mate the aerosol-generating article 1 with the heater without having to distinguish between the functional segment 12 and the stopper 13 during use, thereby increasing the ease of use of the aerosol-generating article 1. Furthermore, the symmetrical arrangement of the functional segment 12 and the stopper 13 with respect to the dielectric segment 11 also enhances the aesthetic appearance of the aerosol-generating article 1.

[0123] The specific structure of the functional section 12 is not limited.

[0124] For example, in some examples, please refer to Figures 1 to 7, the functional segment 12 is a single-stage structure, and the single-stage structure includes one of the cooling segment 121, the support segment 122, and the filtering segment 123. That is, the functional segment 12 can only include the cooling segment 121, the functional segment 12 can only include the support segment 122, and the functional segment 12 can also only include the filtering segment 123.

[0125] In other examples, please refer to Figures 8 to 9 and Figures 11 to 12. The functional section 12 is a multi-section combination structure, which includes at least two of the cooling section 121, the support section 122, and the filtering section 123. That is, the functional section 12 may include two of the cooling section 121, the support section 122, and the filtering section 123. The functional section 12 may also include three of the cooling section 121, the support section 122, and the filtering section 123.

[0126] For example, in some embodiments, please refer to Figure 9, the functional section 12 includes a cooling section 121 and a filtering section 123. The filtering section 123 is arranged at the end of the cooling section 121 away from the medium section 11, and the air inlet channel 12a is arranged in the cooling section 121. The aerosol flows out of the aerosol generating product 1 through the cooling section 121 and the filtering section 123. The cooling section 121 reduces the temperature of the aerosol, making the use temperature of the aerosol more suitable. The filtering section 123 filters impurities or harmful components entrained in the aerosol, thereby enhancing the user experience.

[0127] In other embodiments, the functional section 12 includes a cooling section 121 , a supporting section 122 and a filtering section 123 , and the cooling section 121 and the supporting section 122 are disposed between the medium section 11 and the filtering section 123 .

[0128] The cooling section 121 can be arranged between the supporting section 122 and the filtering section 123, please refer to Figures 11 and 12, that is, the aerosol flows out of the aerosol generating product 1 through the supporting section 122, the cooling section 121, and the filtering section 123. The supporting section 122 connects the medium section 11 and the cooling section 121 on both sides of the support and can assist in cooling. The cooling section 121 reduces the temperature of the aerosol, and the filtering section 123 filters impurities or large particulate matter entrained in the aerosol, thereby enhancing the user experience.

[0129] The cooling section 121 can also be arranged between the medium section 11 and the support section 122. That is, the aerosol flows out of the aerosol generating product 1 through the cooling section 121, the support section 122, and the filtering section 123. The cooling section 121 reduces the temperature of the aerosol. The support section 122 connects the cooling section 121 and the filtering section 123 on both sides of the support and can assist in cooling. The filtering section 123 filters impurities or large particulate matter entrained in the aerosol, thereby enhancing the user experience.

[0130] The structures of the cooling section 121 , the supporting section 122 and the filtering section 123 are not limited.

[0131] The cooling section 121 may be a hollow tubular structure, for example, a hollow acetate fiber structure, a hollow aluminum foil tube structure, a hollow silica gel structure, a hollow PET (polyethylene glycol terephthalate) structure, etc.

[0132] The support section 122 may be a hollow tubular structure, a hollow acetate fiber structure, a hollow aluminum foil tube structure, a hollow silicone structure, a hollow PET (polyethylene glycol terephthalate) structure, or the like.

[0133] The filter section 123 can be a solid acetate fiber structure. On the one hand, it can filter impurities or harmful substances contained in the aerosol, absorb condensation liquid or large particle droplets formed by aerosol condensation, keep the aerosol dry, and enhance the user experience. On the other hand, it can also adjust the suction resistance so that the aerosol content generated per unit time is more reasonable.

[0134] In some embodiments, please refer to Figure 10, the dielectric segment 11 and the functional segment 12 are spaced apart to form a first cavity 101a. The first cavity 101a has a larger space, which can increase the contact area with the aerosol to reduce the temperature of the aerosol. It can also reduce the probability of aerosol deposition on the contact surface between the functional segment 12 and the dielectric segment 11, improve the aerosol extraction rate, and also facilitate the storage of the aerosol.

[0135] It is understood that the first air inlet 10a can pass through the portion of the first encapsulating segment 101 corresponding to the first cavity 101a, or can pass through the portion of the first encapsulating segment 101 corresponding to the functional segment 12. For example, referring to FIG. 10 , the first air inlet 10a can pass through the portion of the first encapsulating segment 101 corresponding to the first cavity 101a.

[0136] In some embodiments, at least two of the multi-segmented structures are spaced apart to form a second cavity 101b. This facilitates the entry of air from the external environment to extract the aerosol and reduces the chance of aerosol depositing on the contact surface of two adjacent structures. Furthermore, it reduces the temperature of the aerosol, making it more suitable for use.

[0137] It can be understood that the first air inlet 10a can pass through the portion of the first wrapping segment 101 corresponding to the second cavity 101b, and the first air inlet 10a can also pass through the portion of the first wrapping segment 101 corresponding to the functional segment 12.

[0138] It can be understood that there are many situations in which at least two combined structures are spaced apart and form the second cavity 101b.

[0139] In the first type, the cooling section 121 and the supporting section 122 are spaced apart to form a second cavity 101 b.

[0140] In the second method, the cooling section 121 and the filtering section 123 are spaced apart to form a second cavity 101 b.

[0141] The third type is that the supporting section 122 and the filtering section 123 are spaced apart and form a second cavity 101b.

[0142] For example, referring to FIG12 , the functional section 12 includes a cooling section 121, a supporting section 122, and a filtering section 123. The cooling section 121 and the filtering section 123 are spaced apart to form a second cavity 101 b. The second cavity 101 b has a larger space, which can increase the contact area with the aerosol so as to reduce the temperature of the aerosol. It can also reduce the probability of the aerosol being deposited on the contact surface between the cooling section 121 and the filtering section 123, thereby improving the extraction rate of the aerosol and facilitating the storage of the aerosol.

[0143] It is understandable that the first wrapping section 101 may have only the first cavity 101a, or only the second cavity 101b, or may have both the first cavity 101a and the second cavity 101b.

[0144] Of course, in other embodiments, please refer to Figures 2, 3, 5, 7 to 9, the two ends of the dielectric segment 11 along the length direction are in contact with the functional segment 12 and the stopper 13 respectively, that is, there is no cavity between the dielectric segment 11 and the functional segment 12, and there is no cavity between the dielectric segment 11 and the stopper 13. The two ends of the dielectric segment 11 along the length direction can be respectively abutted against the functional segment 12 and the stopper 13. In this way, it is convenient to increase the structural stability of the dielectric segment 11, reduce the difficulty of docking the dielectric segment 11, the functional segment 12 and the stopper 13, and facilitate assembly.

[0145] The structure of the stopper 13 is not limited.

[0146] In some examples, the stopper 13 is one of: a film structure with breathable function, a mesh structure, a solid acetate fiber structure, a hollow tubular structure, a structure formed by setting a partition in a hollow tubular structure, and an extruded porous structure.

[0147] When the stopper 13 is a film structure with a breathable function, please refer to Figure 7. The film structure is provided with many micropores. On the one hand, the probability of the medium segment 11 falling out of the wrapping layer 10 after heating can be reduced, and the condensate formed by the condensation of the aerosol can be adsorbed, thereby reducing the probability of the condensate falling from the wrapping layer 10 and contaminating the aerosol generating device; on the other hand, the size of the aerosol generating product 1 along the length direction can be reduced, making the structure of the aerosol generating product 1 more compact, or, without changing the length of the aerosol generating product 1, the length of the medium segment 11 can be increased, thereby increasing the aerosol content.

[0148] It is understood that micropores are pores in a microscopic sense, that is, they cannot be directly identified by the naked eye.

[0149] When the stopper 13 is a mesh structure, please refer to Figure 11. The size of the stopper 13 along the length direction is very small. The stopper 13 can be interwoven with a plurality of crisscrossing filamentary structures. On the basis of achieving stopping cooperation with the heated and shrunk medium segment 11, it can effectively reduce the overall size of the aerosol generating product 1, which is conducive to reducing the structure and making it more compact.

[0150] When the stopper 13 is a solid acetate fiber structure, please refer to Figure 9. On the one hand, it can absorb the condensate formed by the condensation of the aerosol, reduce the probability of the condensate escaping from the wrapping layer 10 and causing pollution to the aerosol generating device, and facilitate the cleaning of the aerosol generating device. On the other hand, it can increase the suction resistance, so that the aerosol content generated per unit time is more reasonable, thereby increasing the user experience.

[0151] When the stopper 13 is a hollow tubular structure, please refer to Figure 3. On the one hand, it can reduce the probability of the medium segment 11 falling out of the wrapping layer 10 after heating and shrinking. On the other hand, due to its hollow structure, it is beneficial for the medium segment 11 to be fully heated, which facilitates the extraction of aerosol.

[0152] The hollow tubular structure may be a hollow paper tube, a hollow aluminum foil paper tube, a hollow acetate fiber structure, a hollow PET (polyethylene glycol terephthalate) structure, a hollow corrugated structure, a hollow silica gel structure, or the like.

[0153] When the stopper 13 is a structure formed by disposing a partition in a hollow tubular structure, the partition can further enhance the stopping capability of the stopper 13 and provide sufficient support for the medium segment 11 .

[0154] When the stopper 13 is an extruded porous structure, as shown in FIG10 , aerosol condensate can also be absorbed by the porous structure, thereby increasing the stopping reliability of the stopper 13. In some examples, when the stopper 13 is an extruded porous structure, the porous structure abuts against the airway holes 11a, facilitating heating of the medium segment 11 and facilitating aerosol extraction.

[0155] Of course, in other embodiments, the stopper 13 may be an injection-molded porous structure or a die-cast porous structure.

[0156] In some examples, the stopper 13 may further include an aerosol generating matrix, which can participate in heating, provide aerosol, and increase aerosol content while preventing the medium segment 11 from falling out of the wrapping layer 10 after being deformed by heat.

[0157] The molding method of the stopper 13 is not limited. For example, the stopper 13 can be an integrally molded structure, which has a simple molding method and a fast molding speed.

[0158] The materials of the cooling section 121 , the support section 122 , and the filtering section 123 are not limited. For example, the materials of the cooling section 121 , the support section 122 , and the filtering section 123 include, but are not limited to, one or more combinations of PE (polyethylene), PLA (Polylactic acid, also known as polylactide), PBAT (Poly (butylene adipate-co-terephthalate), PP (Polypropylene), acetate fiber, and propylene fiber materials.

[0159] It is understandable that the materials of the supporting section 122 , the cooling section 121 , and the filtering section 123 may be the same or different.

[0160] In some embodiments, the stopper 13, the dielectric segment 11, and the functional segment 12 have the same cross-section and dimensions. This facilitates the assembly and coordination of the stopper 13, the dielectric segment 11, and the functional segment 12, reduces the size requirements for the wrapping layer 10, and increases the installation reliability of the aerosol-generating article 1.

[0161] The molding method of the stopper 13 and the functional section 12 is not limited. The stopper 13 and the functional section 12 can be integrally molded by extrusion molding, injection molding, die-casting, etc.

[0162] The cross-sectional shape of the aerosol-generating article 1 is not limited. In some examples, the cross-sectional shape of the aerosol-generating article 1 is generally circular, i.e., the aerosol-generating article 1 as a whole is generally cylindrical; in other examples, the cross-sectional shape of the aerosol-generating article 1 is generally rectangular, i.e., the aerosol-generating article 1 as a whole is generally in the shape of a rectangular column.

[0163] In some embodiments, referring to Figures 1 to 3 and Figures 6 to 12, the functional segment 12, the dielectric segment 11, and the stopper 13 are cylinders with the same outer diameter and coaxially arranged, and the length direction is the axial direction of the functional segment 12, the dielectric segment 11, and the stopper 13.

[0164] The functional segment 12 , the medium segment 11 , and the stopper 13 are butted together along the axial direction, which simplifies the matching of the segments and reduces the difficulty of wrapping the wrapping layer 10 outside the segments, thereby reducing the difficulty of manufacturing the aerosol generating product 1 .

[0165] The following briefly describes the airflow mode in conjunction with nine embodiments shown in the accompanying drawings.

[0166] First embodiment:

[0167] Please refer to Figures 1 and 2. The functional segment 12 is a single-stage structure. The functional segment 12 has a hollow space 12g. The first air inlet 10a penetrates the side wall of the first wrapping segment 101, and the second air inlet 12a penetrates the inner wall surface 12f and the outer wall surface 12e of the functional segment 12. The air in the external environment can enter the hollow space 12g through the first air inlet 10a and the second air inlet 12a, and then enter the interior of the medium segment 11 for diffusion.

[0168] The interior of the medium segment 11 has micropores, which are at least partially interconnected and connected to the airway pores 11a. Aerosol generated by the portion of the medium segment 11 surrounding the airway pores 11a (i.e., the portion of the medium segment 11 exposed to the airway pores 11a) directly enters the airway pores 11a, while aerosol generated by other portions of the medium segment 11 (i.e., the portion of the medium segment 11 not exposed to the airway pores 11a) can be collected within the airway pores 11a through the micropores. Thus, during inhalation, air entering from the second air inlet 12a through the hollow space 12g can entrain the aerosol collected within the airway pores 11a and flow out of the aerosol-generating article 1 through the hollow space 12g, entering the user's oral cavity.

[0169] Second embodiment:

[0170] Please refer to Figure 3. The functional segment 12 is a single-stage structure. The functional segment 12 and the stopper 13 have the same structure. The inner wall surface 12f of the functional segment 12 encloses a hollow space 12g. The first air inlet 10a penetrates the side wall of the first wrapping segment 101, and the second air inlet 12a penetrates the outer wall surface 12e and the inner wall surface 12f of the functional segment 12. The air in the external environment can enter the hollow space 12g through the first air inlet 10a and the second air inlet 12a, and then enter the interior of the medium segment 11 for diffusion.

[0171] The interior of the medium segment 11 has micropores, which are at least partially interconnected and connected to the airway pores 11a. Aerosol generated by the portion of the medium segment 11 surrounding the airway pores 11a (i.e., the portion of the medium segment 11 exposed to the airway pores 11a) directly enters the airway pores 11a, while aerosol generated by other portions of the medium segment 11 (i.e., the portion of the medium segment 11 not exposed to the airway pores 11a) can be collected within the airway pores 11a through the micropores. Thus, during inhalation, air entering from the second air inlet 12a through the hollow space 12g can entrain the aerosol collected within the airway pores 11a and flow out of the aerosol-generating article 1 through the hollow space 12g, entering the user's oral cavity.

[0172] Third embodiment:

[0173] Please refer to Figures 4 and 5. The functional segment 12 is a single-segment structure. The circumferential outer surface of the functional segment 12 has a groove 12c. The inner wall surface 12f of the functional segment 12 encloses a hollow space 12g. The gap between the end of the first wrapping segment 101 and the functional segment 12 defines a first air inlet 10a. At least part of the groove 12c overlaps with the airway hole 11a. Air in the external environment can enter the groove 12c through the first air inlet 10a, and then enter the interior of the medium segment 11 for diffusion.

[0174] The interior of the media segment 11 has micropores, which are at least partially interconnected and connected to the airway pores 11a. Aerosol generated by the portion of the media segment 11 surrounding the airway pores 11a (i.e., the portion of the media segment 11 exposed to the airway pores 11a) directly enters the airway pores 11a, while aerosol generated by other portions of the media segment 11 (i.e., the portion of the media segment 11 not exposed to the airway pores 11a) can be collected within the airway pores 11a through the micropores. Thus, during inhalation, air entering from the first air inlet 10a through the groove 12c can entrain the aerosol collected within the airway pores 11a and flow out of the aerosol-generating article 1 through the hollow space 12g, entering the user's oral cavity.

[0175] Fourth embodiment:

[0176] Please refer to Figures 6 and 7. The functional segment 12 is a single-stage structure. The inner wall surface 12f of the functional segment 12 encloses a hollow space 12g. The first air inlet 10a passes through the side wall of the first wrapping segment 101. There is a groove 12i between the inner wall surface 12f and the outer wall surface 12e. The second air inlet 12a passes through the inner and outer walls of the functional segment 12. At this time, the air in the external environment has two paths to enter the medium segment 11.

[0177] First, air from the external environment can enter the groove 12i through the second air inlet 12a, and then enter the interior of the dielectric segment 11 through the groove 12i for diffusion;

[0178] Article 2: Air in the external environment can enter the hollow space 12g through the second air inlet 12a, and then enter the interior of the medium segment 11 through the hollow space 12g to be diffused.

[0179] The interior of the medium segment 11 has micropores, which are at least partially interconnected and connected to the airway pores 11a. Aerosol generated by the portion of the medium segment 11 surrounding the airway pores 11a (i.e., the portion of the medium segment 11 exposed to the airway pores 11a) directly enters the airway pores 11a. Aerosol generated by other portions of the medium segment 11 (i.e., the portion of the medium segment 11 not exposed to the airway pores 11a) can be collected within the airway pores 11a through the micropores. Thus, during inhalation, air entering the medium segment 11 through the two aforementioned paths can carry the collected aerosol with it, exit the aerosol-generating article 1 through the hollow space 12g, and enter the user's oral cavity.

[0180] Fifth embodiment:

[0181] Please refer to Figure 8. The functional section 12 is a multi-section combination structure. The functional section 12 includes a cooling section 121 and a filtering section 123. The second air inlet 12a is provided in the cooling section 121. The air in the external environment can enter the hollow space 12g through the second air inlet 12a and then enter the interior of the medium section 11 for diffusion.

[0182] Sixth embodiment:

[0183] Please refer to Figure 9. The functional section 12 is a multi-section combination structure. The functional section 12 includes a cooling section 121 and a filtering section 123. The second air inlet 12a is provided in the cooling section 121. The air in the external environment can enter the channel 12i through the second air inlet 12a and then enter the interior of the medium section 11 for diffusion. The air entering the medium section 11 can carry the collected aerosol through the cooling section 121 and the filtering section 123 to flow out of the aerosol generating product 1 and enter the user's mouth.

[0184] Seventh embodiment:

[0185] Please refer to Figure 10. The functional segment 12 is a single-segment structure. The inner wall surface 12f of the functional segment 12 encloses a hollow space 12g. The functional segment 12 and the dielectric segment 11 are spaced apart to form a first cavity 101a. The first air inlet 10a penetrates the side wall of the first wrapping segment 101 corresponding to the first cavity 101a. The air in the external environment can enter the first cavity 101a through the first air inlet 12a and diffuse inside the dielectric segment 11.

[0186] The interior of the medium segment 11 has micropores, which are at least partially interconnected and connected to the airway pores 11a. Aerosol generated by the portion of the medium segment 11 surrounding the airway pores 11a (i.e., the portion of the medium segment 11 exposed to the airway pores 11a) directly enters the airway pores 11a, while aerosol generated by other portions of the medium segment 11 (i.e., the portion of the medium segment 11 not exposed to the airway pores 11a) can be collected within the airway pores 11a through the micropores. Thus, during inhalation, air entering the medium segment 11 from the first air inlet 12a through the first cavity 101a can carry the collected aerosol and flow out of the aerosol-generating article 1 through the first cavity 101a and the hollow space 12g, entering the user's oral cavity.
