Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, the meaning of "plurality" refers to two or more.

[0054] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] The present application embodiment provides an aerosol generating product 1, see Figures 1 to 12 , including a wrapping layer 10, a medium segment 11, a functional segment 12 and a stopper 13.

[0056] The embodiment of the present application provides an aerosol generating system, including an aerosol generating device and an aerosol generating article 1 of any embodiment of the present application. The aerosol generating article 1 can be plugged in and out of the aerosol generating device, and the aerosol generating device includes a heating element, which is used to heat the medium segment 11 to generate an aerosol, and the aerosol can be discharged from the aerosol generating device for inhalation by a user.

[0057] The medium segment 11 is used to generate aerosol, that is, at least a part of the medium segment 11 is composed of an aerosol generating substrate, so that the medium segment 11 can generate aerosol for use by users.

[0058] The specific form of the heating element is not limited, and it can be a resistive heating film, an electromagnetic induction heating element, an infrared heating coating, a laser heating element, etc., and is not limited here.

[0059] 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 .

[0060] 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.

[0061] It is understandable that the material of the wrapping layer 10 has a certain structural strength to reduce the probability of deformation of the aerosol generating product 1 due to airflow pressure during use. The wrapping layer 10 can be an integrated structure or a combined structure.

[0062] The specific material of the wrapping layer 10 is not limited, such as one or more combinations of fiber paper, metal foil, metal foil composite fiber paper, PE (Polyethylene), polyethylene composite fiber paper, PBAT (Poly (butyleneadipate-co-terephthalate, poly (butylene adipate-co-terephthalate)) and the like.

[0063] The medium segment 11 is an integral structure and is disposed between the functional segment 12 and the stopper 13 .

[0064] 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.

[0065] The portion of the wrapping layer 10 protruding 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 a first air inlet 10a.

[0066] 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.

[0067] That is to say, when in 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.

[0068] It can be understood that in some embodiments, the wrapping layer 10 also includes a second wrapping segment 102 and a third wrapping segment 103 along the length direction, 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 at least a portion of the circumferential outer surface of the stopper 13, the first wrapping segment 101, the second wrapping segment 102 and the third wrapping segment 103 together constitute the wrapping layer 10, 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, 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.

[0069] 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 outside the functional segment 12 and inhale the aerosol through the nozzle.

[0070] 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.

[0071] It should be noted that the stopper 13 and the end of the medium segment 11 away from the functional segment 12 may be cooperated in such a way that the medium 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 and the end of the medium segment 11 away from the functional segment 12 abut against each other, or the stopper 13 and the end of the medium segment 11 away from the functional segment 12 always maintain abutment against each other.

[0072] 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, clamping, 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.

[0073] It is understandable that there is a certain force between the medium segment 11 and the inner wall of the wrapping layer 10 to suppress the tendency of the medium segment 11 to move. For example, the outer circumferential surface of the medium segment 11 fits with the inner wall of the wrapping layer 10, and the position of the medium segment 11 is fixed by the friction between the outer circumferential surface of the medium segment 11 and the inner wall of the wrapping layer 10. The outer circumferential surface of the medium segment 11 and the inner wall of the wrapping layer 10 are in an interference fit or a transition fit, so that there is extrusion between the two, thereby increasing the friction.

[0074] In the related art, the medium segment is easily moved due to the shaking of the aerosol generating product during transportation and use, and the medium segment is easily contracted and deformed during the heating process, thereby falling off from the wrapping layer under the action of gravity, affecting the structural reliability of the aerosol generating product.

[0075] Therefore, in the aerosol generating product 1 provided in the embodiment of the present application, the air in 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 the large change in the atomization temperature of the medium segment 11 caused by the air in the external environment directly entering 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, and the probability of the medium segment 11 escaping from the wrapping layer 10 due to the shaking of the aerosol generating product 1 during transportation and use is reduced; at the same time, the probability of the medium segment 11 shrinking and deforming due to heating and falling from the wrapping layer 10 due to factors such as gravity is also reduced; 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.

[0076] The specific components of the aerosol generating matrix are not limited herein. For example, the aerosol generating matrix may include plant components, auxiliary components, smoke generating agent components, adhesive components, and the like.

[0077] In some embodiments, the plant component is one or more combinations of powders formed by crushing tobacco raw materials, tobacco leaf fragments, tobacco stems, tobacco dust, and aromatic plants. The plant component is the core source of the flavor of the product. Endogenous substances in the plant component, such as nicotine, enter the human blood through atomization, promote the pituitary gland to produce dopamine, and thus obtain physiological satisfaction.

[0078] In some embodiments, the auxiliary agent component can be one or more combinations of inorganic fillers, lubricants, and emulsifiers. Among them, the inorganic filler includes one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. The inorganic filler can provide a skeleton support for the plant component, and the inorganic filler also has micropores, which can increase the porosity of the wall material after the plant component is formed, thereby increasing the aerosol release rate.

[0079] The lubricant includes one or more combinations of candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. The lubricant can increase the fluidity of the particles, reduce the friction between the particles, make the overall density of the particle distribution more uniform, and also reduce the pressure required for mold molding and reduce the wear of the mold.

[0080] Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers (also called surfactants) can reduce the interfacial tension of water-soluble and water-insoluble components in the mixed system, and form a relatively strong film on the surface of the droplets or form a double electric layer on the surface of the droplets due to the charge given by the emulsifier, preventing the droplets from aggregating with each other and maintaining a uniform emulsion. Emulsifying and homogenizing two immiscible components can improve the consistency of product quality.

[0081] The function of the smoke-generating agent component is to generate a large amount of steam when heated, thereby increasing the amount of smoke of the smoking product. In one embodiment, the smoke-generating agent may include, for example: a monohydric alcohol (such as menthol); a polyhydric alcohol (such as propylene glycol, triethylene glycol, 1,3-butylene glycol and glycerol); an ester of a polyhydric alcohol (such as monoacetin, diacetin or triacetin); a monocarboxylic acid; a polycarboxylic acid (such as lauric acid, myristic acid) or an aliphatic ester of a polycarboxylic acid (such as dimethyl dodecanedioate, dimethyl tetradecanedioate, erythritol, 1,3-butylene glycol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, Triactin, meso-erythritol, diacetin mixture, diethyl suberate, triethyl citrate, benzyl benzoate, benzyl phenylacetate, ethyl vanillate, glyceryl tributyrate, lauryl acetate) or one or more combinations thereof.

[0082] In some embodiments, the adhesive component is a natural plant-extracted, non-ionically modified viscous polysaccharide, including one or more combinations of tamarind polysaccharide, pullulan, seaweed polysaccharide, locust bean gum, guar gum, and xyloglucan. The adhesive is in close contact with the interface of the product component material by wetting, generating an intermolecular attraction, thereby playing the role of bonding the powder, liquid, etc. of the component material. At the same time, the use of natural plant-extracted, non-ionic adhesives can avoid the release of harmful substances such as methanol, formaldehyde, and acrolein caused by colloid modification, thereby improving the safety of the product.

[0083] For some examples, see 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.

[0084] Specifically, when negative pressure is generated by suction, the air in the external environment enters the air inlet channel 12a from the first air inlet 10a, and the air inlet channel 12a guides the air in the external environment to the medium segment 11. After the air in the external environment entrains the aerosol generated by the atomization of the medium segment 11, it flows out of the aerosol generating product 1 under the guidance of the air outlet channel 12a, and is inhaled by the user. On the one hand, the functional segment 12 can guide the air in the external environment to the medium segment 11, and on the other hand, it can guide the aerosol out of the aerosol generating product 1 for the user to inhale, so that the structure of the aerosol generating product 1 can be made more compact and highly reliable.

[0085] For some examples, see Figure 2 , Figure 3 , Figure 5 , Figures 7 to 12 The medium segment 11 has at least one air passage hole 11 a, and the air passage hole 11 a passes through at least one end of the medium segment 11 close to the functional segment 12 along the length direction.

[0086] 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 extraction rate of the aerosol.

[0087] It should be noted that there are many 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.

[0088] 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 in an open state, and the end away from the functional segment 12 is in a closed state, and the airway hole 11a is formed as a blind hole.

[0089] 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.

[0090] The number of the airway holes 11a is not limited, and can be one, or two or more.

[0091] It should be noted that in the embodiment of the present application, the length direction does not specifically refer to the direction in which the outer contour of the medium segment 11 is the longest. The arrangement direction of the stopper 13 and the functional segment 12 is consistent with the length direction; the direction in which the aerosol generating product 1 is inserted into the aerosol generating device and the direction in which the aerosol generating product 1 is taken out of the aerosol generating device are both parallel to the length direction. The dimension of the medium segment 11 along the length direction may be longer, shorter, or the same as the dimension along other directions.

[0092] For example, in some examples, when the appearance of the medium segment 11 is cylindrical, the length direction is the axial direction of the medium segment 11. It should be noted that even if the axial dimension of the medium segment 11 is smaller than its diameter, the length direction of the medium segment 11 is still the axial direction.

[0093] In other examples, when the appearance 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, and height of the rectangular parallelepiped.

[0094] It is understandable that micropores are formed in the medium segment 11, and the micropores are connected to form micro airways. Some of the micropores are connected to the airway holes 11a, and the other micro airways directly penetrate the air inlet and outlet ends of the medium segment 11. In this way, the aerosol can be discharged from the medium segment 11 in a variety of ways. For example, the aerosol generated by the medium segment 11 after heating can directly enter the airway holes 11a and be carried away by the air in the external environment; or, the air in the external environment directly enters the micro airway and discharges the aerosol carried by the micro airway; or, the aerosol enters the airway hole 11a from the micro airway.

[0095] It is understood that the micropores may be partially connected and partially disconnected, or all micropores may be interconnected. For example, in an embodiment in which the medium segment 11 is a particle combination, the gaps between the particles constitute the micropores, wherein the size of the micropores is determined by the gaps between the particles of the medium segment 11.

[0096] It should be noted that the airway holes 11a 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.

[0097] The airway holes 11a and micropores can increase the surface area of ​​the medium segment 11, facilitate heat transfer, and improve heating efficiency. The aerosol-generating matrix in the medium segment 11 releases aerosol when heated, and is transported to the functional segment 12 under the negative pressure generated by the user's inhalation. The airway holes 11a and micropores can reduce the suction resistance of the user's inhalation, improve the user experience, and reduce the adverse effect of the condensed aerosol remaining in the medium segment 11 and affecting the airflow.

[0098] For some examples, see Figures 1 to 3 , Figures 6 to 12 The first wrapping section 101 is provided with a first air inlet 10a, and the first air inlet 10a runs through the side wall of the first wrapping section 101.

[0099] 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, so as to facilitate the extraction of aerosol.

[0100] The number of the first air inlet 10a may be one, or may be two or more.

[0101] It should be noted that if the number of first air inlets is too large, the air intake will be too much, the suction resistance will be small, and the aerosol content inhaled will be small. If the number of first air inlets is too small, the air intake will be too small, the suction resistance will be large, and the aerosol content inhaled will be small, affecting the user experience.

[0102] 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.

[0103] 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 enhancing the user experience.

[0104] In some other embodiments, please refer to Figure 4 and Figure 5 A groove 12c is provided on the circumferential surface of the functional segment 12, and the groove 12c at least passes through 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.

[0105] In this embodiment, the first air inlet 10a is defined by the matching gap between the first wrapping segment 101 and the functional segment 12, and no additional processing is required for the first wrapping segment 101, which reduces the manufacturing requirements for the wrapping layer 10, making the processing steps of the aerosol generating article 1 simpler. The air in the external environment enters from the gap between the end of the first wrapping segment 101 and the functional segment 12, driving the aerosol to flow out from the air outlet channel 12b.

[0106] It can be understood that in this embodiment, one 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 makes the inhalation of the aerosol more convenient and gives the user a better experience.

[0107] 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 penetrate 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, entraining the aerosol to flow out of the aerosol generating product 1 for the user to inhale.

[0108] It can be understood that, in the present embodiment, the groove 12c at least passes through one end of the functional segment 12 close to the dielectric segment 11. It can be that the groove 12c only passes through the end of the functional segment 12 close to the dielectric segment 11, or it can be that 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 far from the dielectric segment 11, that is, the groove 12c passes through both ends of the functional segment 12 along the length direction.

[0109] See also Figure 5 The groove 12c at least partially overlaps with the airway hole 11a, so that the air in the external environment can quickly flow into the airway hole 11a after entering through the first air inlet 10a, so as to improve the extraction efficiency of the aerosol.

[0110] For some examples, see Figure 2 , Figure 3 and Figure 5 The functional section 12 has one or more central air channels 12d, and the one or more central air channels 12d penetrate the functional section 12 along the length direction, and the central air channels 12d overlap with the airway holes 11a at least partially. In other words, the central air channels 12d and the airway holes 11a are at least partially connected, so that the aerosol can be quickly extracted, the aerosol extraction efficiency is increased, and the user experience is improved.

[0111] For some examples, see Figures 6 to 12The 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. The side wall of the functional section 12 is provided with a second air inlet 12h. The second air inlet 12h at least penetrates the outer wall surface 12e, and the second air inlet 12h is connected to the first air inlet 10a.

[0112] 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.

[0113] The second air inlet 12h at least penetrates the outer wall surface 12e. The second air inlet 12h may only penetrate the outer wall surface 12e, or may penetrate both the outer wall surface 12e and the inner wall surface 12f.

[0114] For some examples, see Figure 8 The structure between the inner wall surface 12f and the outer wall surface 12e is a solid structure, and the second air inlet 12h penetrates the inner wall surface 12f and the outer wall surface 12e.

[0115] 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.

[0116] The solid structure can also be a tubular structure such as a paper tube or an aluminum foil tube without an air flow channel formed inside, that is, the functional section 12 is a hollow paper tube structure or a hollow aluminum foil paper tube structure, and the air in the external environment enters the hollow space 12g through the second air inlet 12h, moves toward the medium section 11 and carries the aerosol to the functional section 12. The hollow paper tube structure and the hollow aluminum foil paper tube structure are light in weight, which is convenient for reducing the overall weight of the aerosol generating product 1, and the hollow area can be used to reduce the temperature of the aerosol; and the hollow paper tube structure and the hollow aluminum foil tube structure have good heat resistance, are not easily deformed by heat, and can still maintain their shape after heat conduction, which can increase the structural stability of the aerosol generating product 1. For example, please refer to Figure 8 , the functional section 12 is a hollow paper tube structure.

[0117] Of course, the functional section 12 may also be a hollow silica gel structure, a hollow PET (polyethylene glycol terephthalate) structure, etc., which is not limited here.

[0118] In this embodiment, the second air inlet 12h penetrates both the outer wall surface 12e and the inner wall surface 12f, and the air in the external environment enters through the first air inlet 10a and the second air inlet 12h to extract the aerosol and flows out from the hollow space 12g.

[0119] It can be understood that acetate fiber refers to acetate fiber, also known as cellulose acetate or cellulose acetate, which is a chemically modified polymer compound obtained by esterifying the hydroxyl groups in the cellulose molecules with acetate, including diacetate fiber and triacetate fiber, which has good acid and alkali resistance and organic solvent resistance.

[0120] For some examples, see Fig. 9 A groove 12i is provided between the inner wall surface 12f and the outer wall surface 12e, which penetrates 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.

[0121] It is understandable that in this embodiment, the functional section 12 may be a hollow corrugated tube structure, a porous structure, etc. For example, see Figure 6 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 roughly wavy.

[0122] The communication method between the second air inlet 12h and the groove 12i is not limited.

[0123] For example, in some embodiments, see Fig. 9 , the second air inlet 12h only passes through the outer wall surface 12e, that is, the first air inlet 12h does not pass through the inner wall surface 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 is convenient for the consistency of aerosol extraction. In addition, it is also convenient to cool the aerosol.

[0124] In some other embodiments, please refer to Figure 7 The second air inlet 12h passes through the groove 12i and penetrates the inner wall surface 12f.

[0125] In this embodiment, the second air inlet 12h penetrates 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 12b. That is to say, in this embodiment, the air in the external environment can have two air flow channels, so that more aerosols can be extracted per unit time, which is convenient for improving the aerosol extraction efficiency.

[0126] It should be noted that the number of the second air inlets 12h is not limited, and may be one, or may be two or more.

[0127] 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.

[0128] For some examples, see Figure 3 The functional segment 12 and the stopper 13 have the same structure and are symmetrically arranged with respect to the medium segment 11. In this way, when using, the user does not need to distinguish between the functional segment 12 and the stopper 13, and can be installed and matched with the heating element, thereby increasing the convenience of using the aerosol generating product 1. In addition, the functional segment 12 and the stopper 13 are symmetrically arranged with respect to the medium segment 11, which can also improve the appearance of the aerosol generating product 1.

[0129] The specific structure of the functional section 12 is not limited.

[0130] For some examples, see Figures 1 to 7 The functional section 12 is a single-stage structure, which includes one of the cooling section 121, the supporting section 122, and the filtering section 123. That is to say, the functional section 12 may only include the cooling section 121, the functional section 12 may only include the supporting section 122, or the functional section 12 may only include the filtering section 123.

[0131] For other examples, see Figures 8 to 9 , Figure 11 to Figure 12 The functional section 12 is a multi-section combination structure, which includes at least two of the cooling section 121, the supporting section 122, and the filtering section 123. That is to say, the functional section 12 may include two of the cooling section 121, the supporting section 122, and the filtering section 123, or the functional section 12 may include three of the cooling section 121, the supporting section 122, and the filtering section 123.

[0132] For example, in some embodiments, see Fig. 9The functional section 12 includes a cooling section 121 and a filtering section 123. The filtering section 123 is arranged at one end of the cooling section 121 away from the medium section 11. 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, so that the use temperature of the aerosol is more suitable. The filtering section 123 filters impurities or harmful components contained in the aerosol to increase the user experience.

[0133] 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 .

[0134] The cooling section 121 can be arranged between the supporting section 122 and the filtering section 123, see Fig.11 and Fig.12 That is to say, 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 particles contained in the aerosol, thereby increasing the user experience.

[0135] The cooling section 121 can also be arranged between the medium section 11 and the supporting section 122. That is to say, the aerosol flows out of the aerosol generating product 1 through the cooling section 121, the supporting section 122, and the filtering section 123. The cooling section 121 reduces the temperature of the aerosol. The supporting 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 particles contained in the aerosol to increase the user experience.

[0136] The structures of the cooling section 121 , the supporting section 122 and the filtering section 123 are not limited.

[0137] 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, and the like.

[0138] The support section 122 may be a hollow tubular structure, a hollow acetate fiber structure, a hollow aluminum foil tube structure, a hollow silica gel structure, a hollow PET (polyethylene glycol terephthalate) structure, or the like.

[0139] 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, adsorb condensate or large particle droplets formed by the condensation of the aerosol, 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.

[0140] For some examples, see Fig.10 The medium 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 so as 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 medium segment 11, improve the extraction rate of the aerosol, and also facilitate the storage of the aerosol.

[0141] It is understandable that the first air inlet 10a may pass through the portion of the first encapsulating section 101 corresponding to the first cavity 101a, or may pass through the portion of the first encapsulating section 101 corresponding to the functional section 12. Fig.10 The first air inlet 10a may penetrate the portion of the first wrapping section 101 corresponding to the first cavity 101a.

[0142] In some embodiments, at least two of the multi-stage combined structures are spaced apart to form a second cavity 101b. This facilitates the entry of air from the external environment to extract aerosols and reduces the probability of aerosols being deposited on the contact surfaces of two adjacent combined structures. On the other hand, it can also reduce the temperature of the aerosol, making the use temperature of the aerosol more suitable.

[0143] It can be understood that the first air inlet 10a can pass through the portion of the first encapsulating segment 101 corresponding to the second cavity 101b, and the first air inlet 10a can also pass through the portion of the first encapsulating segment 101 corresponding to the functional segment 12.

[0144] 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.

[0145] In the first type, the cooling section 121 and the supporting section 122 are spaced apart to form a second cavity 101 b.

[0146] In the second method, the cooling section 121 and the filtering section 123 are arranged at intervals to form a second cavity 101b.

[0147] The third type is that the support section 122 and the filter section 123 are arranged at intervals to form a second cavity 101b.

[0148] For example, see Fig.12The 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 101b. The second cavity 101b 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 aerosol deposition 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.

[0149] It can be understood 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.

[0150] Of course, in some other embodiments, please refer to Figure 2 , Figure 3 , Figure 5 , Figures 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.

[0151] The structure of the stopper 13 is not limited.

[0152] In some examples, the stopper 13 is one of: a film structure with air permeability, 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.

[0153] When the stopper 13 is a film structure with a breathable function, please refer to Figure 7 There are many tiny pores in the film structure. 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 to reduce the probability of the condensate falling from the wrapping layer 10 and contaminating the aerosol generating device; on the other hand, the size of the aerosol generating product 1 along the length direction can be reduced, so that the structure of the aerosol generating product 1 is more compact, or, without changing the length of the aerosol generating product 1, the length of the medium segment 11 can be increased, thereby increasing the aerosol content.

[0154] It is to be understood that micropores are pores in a microscopic sense, that is, they cannot be directly identified by the naked eye.

[0155] When the stopper 13 is a mesh structure, please refer to Fig.11The stopper 13 has a very small size along the length direction. The stopper 13 can be formed by interweaving a plurality of criss-cross filamentary structures. On the basis of achieving stop cooperation with the heated and shrunk medium segment 11, the overall size of the aerosol generating product 1 can be effectively reduced, making the structure more compact.

[0156] When the stopper 13 is a solid acetate fiber structure, please refer to Fig. 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 polluting 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.

[0157] When the stopper 13 is a hollow tubular structure, please refer to Figure 3 On the one hand, the probability of the medium segment 11 escaping from the wrapping layer 10 after being heated and shrunk can be reduced. On the other hand, due to its hollow structure, the medium segment 11 is fully heated, which is convenient for the extraction of aerosol.

[0158] The hollow tubular structure can 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, and the like.

[0159] When the stopper 13 is a structure formed by arranging a partition in a hollow tubular structure, the partition can further increase the stopping ability of the stopper 13 and provide sufficient support for the medium segment 11 .

[0160] When the stopper 13 is an extruded porous structure, please refer to Fig.10 The aerosol condensate can also be absorbed by the porous structure, increasing the stopping reliability of the stopper 13. In some examples, when the stopper 13 is an extruded porous structure, the porous structure is connected to the airway hole 11a, which is beneficial to the heating of the medium section 11 and facilitates the extraction of the aerosol.

[0161] Of course, in other embodiments, the stopper 13 may be an injection-molded porous structure or a die-casting porous structure.

[0162] In some examples, the stopper 13 may also include an aerosol generating matrix, which can participate in heating, provide aerosol, and increase aerosol content while preventing the medium segment 11 from falling out of the wrapping layer 10 after being deformed by heat.

[0163] 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.

[0164] The materials of the cooling section 121, the supporting section 122, and the filtering section 123 are not limited. For example, the materials of the cooling section 121, the supporting section 122, and the filtering section 123 include but are not limited to PE (polyethylene), PLA (Polylactic acid, also known as polylactide), PBAT (Poly (butyleneadipate-co-terephthalate), PP (Polypropylene), acetate fiber, and one or more combinations of propylene fiber materials.

[0165] It is understandable that the materials of the support section 122 , the cooling section 121 , and the filtering section 123 may be the same or different.

[0166] In some embodiments, the stopper 13, the dielectric segment 11, and the functional segment 12 have the same cross-section and the same cross-sectional size, which is beneficial to the installation and coordination between the stopper 13, the dielectric segment 11, and the functional segment 12, and can also reduce the size requirements of the wrapping layer 10, thereby increasing the installation reliability of the aerosol generating article 1.

[0167] The molding method of the stopper 13 and the functional segment 12 is not limited. The stopper 13 and the functional segment 12 can be integrally molded by extrusion molding, injection molding, die-casting, etc.

[0168] 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 roughly circular, that is, the aerosol-generating article 1 as a whole is roughly a columnar structure; in other examples, the cross-sectional shape of the aerosol-generating article 1 is roughly rectangular, that is, the aerosol-generating article 1 as a whole is roughly a rectangular column.

[0169] For some examples, see Figures 1 to 3 , Figures 6 to 12 The functional section 12 , the dielectric section 11 , and the stopper 13 are cylinders with the same outer diameter and are coaxially arranged, and the length direction is the axial direction of the functional section 12 , the dielectric section 11 , and the stopper 13 .

[0170] The functional segment 12 , the medium segment 11 , and the stopper 13 are butted together along the axial direction, and the matching of each segment is simple. This can reduce the difficulty of wrapping the wrapping layer 10 outside each segment, thereby reducing the difficulty of manufacturing the aerosol generating product 1 .

[0171] The following is a brief description of the airflow mode in conjunction with nine embodiments shown in the accompanying drawings.

[0172] First embodiment

[0173] See also Figure 1and Figure 2 The functional segment 12 is a single-stage structure, and 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.

[0174] The inside of the medium segment 11 has micropores, and the micropores are at least partially connected to each other and connected to the airway hole 11a. The aerosol generated by the part of the medium segment 11 surrounding the airway hole 11a (i.e., the part of the medium segment 11 exposed to the airway hole 11a) directly enters the airway hole 11a, and the aerosol generated by other parts of the medium segment 11 (i.e., the part of the medium segment 11 not exposed to the airway hole 11a) can be collected into the airway hole 11a through the micropores. In this way, during the inhalation process, the air entering from the second air inlet 12a through the hollow space 12g can carry the aerosol collected in the airway hole 11a and flow out of the aerosol generating product 1 from the hollow space 12g and enter the user's mouth.

[0175] Second embodiment

[0176] See also Figure 3 The functional section 12 is a single-section structure, and the functional section 12 and the stopper 13 have the same structure. The inner wall surface 12f of the functional section 12 encloses a hollow space 12g. The first air inlet 10a penetrates the side wall of the first wrapping section 101, and the second air inlet 12a penetrates the outer wall surface 12e and the inner wall surface 12f of the functional section 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 section 11 for diffusion.

[0177] The inside of the medium segment 11 has micropores, and the micropores are at least partially connected to each other and connected to the airway hole 11a. The aerosol generated by the part of the medium segment 11 surrounding the airway hole 11a (i.e., the part of the medium segment 11 exposed to the airway hole 11a) directly enters the airway hole 11a, and the aerosol generated by other parts of the medium segment 11 (i.e., the part of the medium segment 11 not exposed to the airway hole 11a) can be collected into the airway hole 11a through the micropores. In this way, during the inhalation process, the air entering from the second air inlet 12a through the hollow space 12g can carry the aerosol collected in the airway hole 11a and flow out of the aerosol generating product 1 from the hollow space 12g and enter the user's mouth.

[0178] Third embodiment

[0179] See also Figure 4 and Figure 5The 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. The 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.

[0180] The inside of the medium segment 11 has micropores, and the micropores are at least partially connected to each other and connected to the airway hole 11a. The aerosol generated by the medium of the medium segment 11 surrounding the airway hole 11a (i.e., the part of the medium segment 11 exposed to the airway hole 11a) directly enters the airway hole 11a, and the aerosol generated by other parts of the medium segment 11 (i.e., the part of the medium segment 11 not exposed to the airway hole 11a) can be collected into the airway hole 11a through the micropores. In this way, during the inhalation process, the air entering from the first air inlet 10a through the groove 12c can carry the aerosol collected in the airway hole 11a and flow out of the aerosol generating product 1 from the hollow space 12g and enter the user's mouth.

[0181] Fourth embodiment

[0182] See also Figure 6 and Figure 7 The functional section 12 is a single-section structure, the inner wall surface 12f of the functional section 12 encloses a hollow space 12g, the first air inlet 10a passes through the side wall of the first wrapping section 101, and 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 section 12. At this time, the air in the external environment has two paths to enter the medium section 11.

[0183] First, air in the external environment can enter the groove 12i through the second air inlet 12a, and then enter the interior of the medium segment 11 through the groove 12i to be diffused;

[0184] Article 2: The air in the external environment can enter the hollow space 12g through the second air inlet 12a, and enter the interior of the medium segment 11 through the hollow space 12g to be diffused.

[0185] The inside of the medium segment 11 has micropores, and the micropores are at least partially connected to each other and connected to the airway hole 11a. The aerosol generated by the medium of the medium segment 11 surrounding the airway hole 11a (i.e., the part of the medium segment 11 exposed to the airway hole 11a) directly enters the airway hole 11a, and the aerosol generated by other parts of the medium segment 11 (i.e., the part of the medium segment 11 not exposed to the airway hole 11a) can be collected into the airway hole 11a through the micropores. In this way, during the inhalation process, the air entering the medium segment 11 from the above two paths can carry the collected aerosol and flow out of the aerosol generating product 1 from the hollow space 12g and enter the user's mouth.

The second air inlet 12a is arranged 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. The air entering the medium section 11 can entrain the collected aerosol and flow out of the aerosol generating product 1 through the cooling section 121 and the filtering section 123 to enter the user's mouth.

[0188] Sixth embodiment

[0189] See also Fig. 9 The functional section 12 is a multi-section combination structure, and the functional section 12 includes a cooling section 121 and a filtering section 123.

The first air inlet 10a penetrates the side wall of the first wrapping section 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 medium section 11.

[0192] The inside of the medium segment 11 has micropores, and the micropores are at least partially connected to each other and connected to the airway hole 11a. The aerosol generated by the medium of the medium segment 11 surrounding the airway hole 11a (i.e., the part of the medium segment 11 exposed to the airway hole 11a) directly enters the airway hole 11a, and the aerosol generated by other parts of the medium segment 11 (i.e., the part of the medium segment 11 not exposed to the airway hole 11a) can be collected into the airway hole 11a through the micropores. In this way, during the suction process, the 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 product 1 through the first cavity 101a and the hollow space 12g, and enter the user's mouth.
