Abstract

Embodiments of this application provide an aerosol product and an aerosol generating system. The aerosol product comprises a coating layer (10), a medium segment (11), a functional segment (12), and a locking member (13). The locking member (13) is used to lock and engage with one end of the medium segment (11) furthest from the functional segment (12). The coating layer (10) covers at least a portion of the locking member (13) and at least a portion of the circumferential outer surfaces of the medium segment (11) and the functional segment (12). The portion of the coating layer (10) that protrudes along the longitudinal direction from the portion of the medium segment (11) furthest from the locking member (13) is a first coating section (101), and the functional segment (12) is at least partially provided within the first coating section (101), and the first coating section (101) and / or the functional segment (12) define a first air intake (10a). Since air from the external environment enters through the first air intake (10a) and does not enter directly through the medium segment (11), the temperature uniformity during atomization of the medium segment (11) is improved. The locking engagement between the medium segment (11) and the locking member (13) restricts the range of activity of the medium segment (11) within the coating layer (10), reducing the possibility of the medium segment (11) detaching from the coating layer (10) due to factors such as thermal shrinkage deformation or gravity.

[Modes for carrying out the invention]

[0028] Furthermore, the embodiments and technical features contained herein can be combined with each other, as long as they do not contradict each other. The detailed descriptions of specific embodiments should be understood as interpretive explanations of this application and should not be considered as unreasonable limitations on this application.

[0029] In the description of the embodiments of this application, the directions or positional relationships indicated by terms such as "inside" and "outside" are based on the attached drawings and are used solely for convenience and simplification of the description of the embodiments of this application. They do not indicate or imply that the shown devices or components have a specific direction, are configured in a specific direction, or must be operated in a specific direction, and therefore cannot be understood as limitations on the embodiments of this application.

[0030] The embodiments of this application provide an aerosol product 1. Referring to Figures 1 to 12, it includes a coating layer 10, a medium segment 11, a functional segment 12, and a locking member 13.

[0031] Embodiments of this application provide an aerosol generation system comprising an aerosol generating device and an aerosol product 1 according to any embodiment of this application. The aerosol product 1 can be inserted into and removed from the aerosol generating device, the aerosol generating device includes a heating member which heats a medium segment 11 to generate an aerosol, and the aerosol can be discharged from the aerosol generating device and offered for use by the user for suction.

[0032] The media segment 11 is for generating aerosols. That is, at least a portion of the media segment 11 is composed of an aerosol-generating substrate, enabling the media segment 11 to generate aerosols for use by the user.

[0033] The specific form of the heating element is not limited and may include resistance heating films, electromagnetic induction heating elements, infrared heating coatings, laser heating elements, etc., and is not particularly limited here.

[0034] The coating layer 10 covers at least a portion of the locking member 13, the media segment 11, and at least a portion of the functional segment 12 in the circumferential outer surface.

[0035] Specifically, in the manufacturing process, the coating layer 10 is directly applied to at least a portion of the locking member 13, the media segment 11, and the functional segment 12 by a winding process, thereby integrating the locking member 13, the media segment 11, and the functional segment 12 into a single unit. This improves the overall structural strength of the aerosol product 1, reduces the possibility of each part of the aerosol product 1 separating and becoming non-functional during transportation and use, and enhances the reliability of the aerosol product 1.

[0036] As can be understood, the material of the coating layer 10 has a certain structural strength, reducing the possibility of deformation occurring due to airflow pressure during the use of the aerosol product 1. The coating layer 10 may be a single-piece structure or a combination structure.

[0037] The specific material of the coating layer 10 is not limited and may be one or a combination of several materials such as fiber paper, metal foil, metal foil composite fiber paper, PE (Polyethylene), polyethylene composite fiber paper, and PBAT (Poly(butylene adipate-co-terephthalate)).

[0038] The media segment 11 has an integrated structure and is provided between the functional segment 12 and the locking member 13.

[0039] In other words, the media segment 11 is an integrally molded structure, such as integral extrusion molding, integral injection molding, or integral die casting.

[0040] The portion of the coating layer 10 that protrudes along the longitudinal direction from the portion of the medium segment 11 furthest from the locking member 13 is the first coating section 101, and the functional segment 12 is provided at least partially within the first coating section 101, and the first coating section 101 and / or the functional segment 12 define the first air intake port 10a.

[0041] The definition of the first air intake port 10a by the first covering section 101 and / or the functional segment 12 includes a variety of situations, in which the first covering section 101 may define the first air intake port 10a, the functional segment 12 may define the first air intake port 10a, or the first covering section 101 and the functional segment 12 may jointly define the first air intake port 10a.

[0042] In other words, when a negative pressure is generated by suction during use, air from the external environment enters the aerosol product 1 through the first air intake port 10a and then moves toward the media segment 11. As a result, the media segment 11 atomizes, and the resulting aerosol flows out of the aerosol product 1 and is available for the user to inhale.

[0043] As can be understood, in some embodiments, the coating layer 10 further includes a second coating section 102 and a third coating section 103 along the longitudinal direction, the first coating section 101, the second coating section 102 and the third coating section 103 are sequentially connected along the longitudinal direction, the second coating section 102 covers the circumferential outer surface of the medium segment 11 and the third coating section 103 covers at least a portion of the circumferential outer surface of the locking member 13, and the first coating section 101, the second coating section 102 and the third coating section 103 together constitute the coating layer 10. The first coating section 101, the second coating section 102 and the third coating section 103 may be integrally molded structures, i.e., the coating layer 10 is an integral structure, and the first coating section 101, the second coating section 102 and the third coating section 103 may be independent parts that are assembled to constitute the coating layer 10, i.e., the coating layer 10 is a combination structure.

[0044] Furthermore, if the first covering section 101 covers the entire circumferential outer surface of the functional segment 12, the user can use the aerosol by directly placing the first covering section 101 in their mouth. If the first covering section 101 covers only a portion of the circumferential outer surface of the functional segment 12, the user can inhale the aerosol by directly placing the portion of the functional segment 12 exposed from the first covering section 101 in their mouth. Naturally, the user can also place a mouthpiece over the outside of the functional segment 12 and inhale the aerosol through the mouthpiece.

[0045] The locking member 13 is used to lock and engage with one end of the media segment 11 that is farther from the functional segment 12. That is, the locking member 13 can abut against one end of the media segment 11 that is farther from the functional segment 12, thereby suppressing movement of the media segment 11 in the direction away from the functional segment 12, and thereby preventing the media segment 11 from escaping from the coating layer 10.

[0046] Furthermore, the locking engagement between the locking member 13 and one end of the media segment 11 furthest from the functional segment 12 may be such that the media segment 11 and the locking member 13 are spaced apart, and the locking member 13 moves a certain distance away from the functional segment 12 before coming into contact with the end of the media segment 11 furthest from the functional segment 12, or the locking member 13 may always be in contact with the end of the media segment 11 furthest from the functional segment 12.

[0047] As can be understood, the method of coupling between the locking member 13 and the coating layer 10 is not limited. For example, in some embodiments, the locking member 13 may be coupled to the coating layer 10 by an interlocking fit, and in some other embodiments, the locking member 13 may be coupled to the coating layer 10 by adhesive, snap-fit, or the like. In this way, the locking member 13 is more securely fixed on the coating layer 10 and is convenient for locking and engaging with the media segment 11.

[0048] As can be understood, a certain force exists between the media segment 11 and the inner wall of the coating layer 10, suppressing the tendency of the media segment 11 to move. For example, the outer circumferential surface of the media segment 11 is in close contact with the inner wall of the coating layer 10, and the frictional force between the outer circumferential surface of the media segment 11 and the inner wall of the coating layer 10 fixes the position of the media segment 11. The relationship between the outer circumferential surface of the media segment 11 and the inner wall of the coating layer 10 is an interference fit or a partial fit, creating pressure between them and increasing the frictional force.

[0049] In related technologies, during transportation and use, the media segment is prone to movement due to the shaking of the aerosol product, and the media segment is prone to shrinkage and deformation during heating, which can cause it to detach from the coating layer under the influence of gravity, affecting the structural reliability of the aerosol product.

[0050] Therefore, in the aerosol product 1 provided by the embodiment of this application, since air from the external environment enters from the first air intake port 10a and does not enter directly through the medium segment 11, the temperature uniformity during atomization of the medium segment 11 is improved, and the possibility of differences in the generated aerosol components due to large changes in the atomization temperature of the medium segment 11 caused by air from the external environment entering directly through the medium segment 11 is reduced. The locking engagement between the medium segment 11 and the locking member 13 restricts the range of activity of the medium segment 11 within the coating layer 10, stabilizing the position of the medium segment 11 within the coating layer 10, and reducing the possibility of the medium segment 11 escaping from the coating layer 10 due to shaking of the aerosol product 1 during transport and use. At the same time, the possibility of the medium segment 11 deforming due to heat shrinkage and falling off the coating layer 10 due to factors such as gravity is also reduced. Furthermore, the locking member 13 adjusts the suction resistance, reducing the possibility of condensate generated after aerosol condensation leaking out of the aerosol product 1, thereby improving the user experience.

[0051] The specific components of the aerosol-generating substrate are not particularly limited here. For example, the aerosol-generating substrate may include plant components, auxiliary components, smoke-generating components, binder components, etc.

[0052] In some embodiments, the plant component is one or a combination of powders formed after crushing tobacco leaf raw materials, tobacco leaf fragments, tobacco stems, tobacco powder, flavoring plants, etc. The plant component is the core source of the flavor of the article, and endogenous substances in the plant component, such as nicotine, enter the bloodstream through atomization, promoting the production of dopamine by the pituitary gland, thereby providing a physiological sense of satisfaction.

[0053] In some embodiments, the auxiliary component may be one or a combination of inorganic fillers, lubricants, and emulsifiers. Here, the inorganic filler includes one or a combination of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc powder, and diatomaceous earth. The inorganic filler can provide skeletal support to the plant components, and at the same time, the inorganic filler has micropores, which can improve the porosity of the wall material after molding of the plant components, thereby improving the aerosol release rate.

[0054] The lubricant contains one or more of the following: 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 frictional force between particles, make the overall density of the particle distribution relatively uniform, reduce the pressure required for mold molding, and reduce mold wear.

[0055] The emulsifier includes one or a combination of polyglycerin fatty acid esters, Tween-80, and polyvinyl alcohol (PVA). The emulsifier (also called a surfactant) can reduce the interfacial tension of water-soluble and water-insoluble components in the mixture, and can form a strong thin film on the surface of the microdroplets, or an electrical double layer on the surface of the microdroplets due to the charge provided by the emulsifier, thereby preventing aggregation of microdroplets and maintaining a uniform emulsion. Emulsification and homogenization of two miscible components can improve the uniformity of the product quality.

[0056] The function of the fumigant component is to generate a large amount of vapor when heated, thereby improving the amount of smoke produced by the fumigating article. In one example, the fumigant may include, for example, one or more combinations of monohydric alcohols (e.g., menthol), polyhydric alcohols (e.g., propylene glycol, triethylene glycol, 1,3-butanediol, and glycerin), esters of polyhydric alcohols (e.g., glyceryl monoacetate, glyceryl diacetate, or glyceryl triacetate), monocarboxylic acids, polycarboxylic acids (e.g., lauric acid, myristic acid), or aliphatic esters of polycarboxylic acids (e.g., dimethyl dodecanediate, dimethyl tetradecanediate, erythritol, 1,3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, triacetin, mesoerythritol, glyceryl diacetate mixture, diethyl suberate, triethyl citrate, benzyl benzoate, benzyl phenylacetate, ethyl vanillate, glyceryl tributyrate, lauryl acetate).

[0057] In some examples, the binder component is a natural plant extract or a non-ionized modified viscous polysaccharide, and includes one or more of the following: tamarind polysaccharide, pullulan polysaccharide, seaweed polysaccharide, locust bean gum, guar gum, and xyloglucan (woody glucan). The binder wets and tightly contacts the component material interface of the article, generating intermolecular attractive forces, thereby acting as an adhesive between the powder, liquid, and other component materials. At the same time, by selectively using natural plant extracts and non-ionized modified binders, the release of harmful substances such as methanol, formaldehyde, and acrolein caused by colloidal modification can be avoided, thereby improving the safety of the article.

[0058] In some embodiments, referring to Figures 1 to 9, the functional segment 12 has an intake channel 12a and an exhaust channel 12b, one end of the intake channel 12a is connected to the first intake port 10a and the other end is connected to the exhaust channel 12b, which leads the aerosol out of the aerosol product 1.

[0059] Specifically, when negative pressure is generated by suction, air from the external environment enters the intake channel 12a from the first intake port 10a. The intake channel 12a guides the air from the external environment to the media segment 11. After the air from the external environment is atomized by the media segment 11 and entrains the generated aerosol, it flows out of the aerosol product 1 under the guidance of the exhaust channel 12b, and is thereby drawn in by the user. The functional segment 12 can, on the one hand, guide air from the external environment to the media segment 11, and on the other hand, lead the aerosol out of the aerosol product 1 for the user's inhalation. In this way, the structure of the aerosol product 1 can be made more compact and reliable.

[0060] In some embodiments, referring to Figures 2, 3, 5, 7 through 12, the media segment 11 has at least one airway opening 11a, the airway opening 11a passing through at least one end of the media segment 11 on the side closer to the functional segment 12 along the longitudinal direction.

[0061] In this way, the aerosol generated by the heat absorption and atomization of the media segment 11 can be released directly from the airway opening 11a and flow out toward the exhaust channel 12b, providing the aerosol with sufficient release space and improving the aerosol extraction rate.

[0062] Furthermore, the fact that the airway opening 11a penetrates at least one end of the media segment 11 closest to the functional segment 12 along its longitudinal direction includes a variety of situations.

[0063] In the first type, the airway opening 11a penetrates only one end of the media segment 11 that is closer to the functional segment 12. That is, one end of the airway opening 11a that is closer to the functional segment 12 is open, and the other end that is further away from the functional segment 12 is closed, so the airway opening 11a is formed as a dead hole.

[0064] In type 2, the airway opening 11a penetrates both ends of the medial segment 11 along its longitudinal direction; that is, one end of the airway opening 11a closer to the functional segment 12 is open, and the other end further away from the functional segment 12 is also open.

[0065] The number of airway openings 11a is not limited; there may be one or two or more.

[0066] In the embodiments of this application, the longitudinal direction does not specifically refer to the direction in which the external contour of the media segment 11 is longest. The arrangement direction of the locking member 13 and the functional segment 12 coincides with the longitudinal direction, and the direction in which the aerosol product 1 is inserted into the aerosol generator and the direction in which the aerosol product 1 is removed from the aerosol generator are both parallel to the longitudinal direction. The dimensions of the media segment 11 along the longitudinal direction may be longer, shorter, or the same as the dimensions along other directions.

[0067] For example, in some cases, if the external contour of the media segment 11 is cylindrical, the longitudinal direction is the axial direction of the media segment 11. Even if the axial dimension of the media segment 11 is smaller than its diameter, the longitudinal direction of the media segment 11 is still the axial direction.

[0068] In some other examples, when the external contour of the media segment 11 is a rectangular parallelepiped, the longitudinal direction is still the direction defined above, namely the arrangement direction of the locking member 13 and the functional segment 12, or the direction in which the aerosol product 1 is inserted and removed, and the longitudinal direction of the media segment 11 may be any one of the directions of the length, width, and height of the rectangular parallelepiped.

[0069] As can be understood, micropores are formed in the media segment 11, and these micropores communicate with each other to form microairways. Some micropores communicate with airway openings 11a, while other microairways directly penetrate the inhalation and exhaust ends of the media segment 11. In this way, aerosols can be discharged from the media segment 11 in various ways. For example, aerosols generated after heating the media segment 11 can enter directly into the airway openings 11a and be drawn into the air in the external environment and discharged. Alternatively, air in the external environment can enter the microairways directly, drawing in and discharging the aerosols in the microairways. Or, aerosols can enter the airway openings 11a from the microairways.

[0070] As can be understood, communication between micropores may be such that some micropores communicate and some do not, or all micropores communicate with each other. For example, in an embodiment in which the media segment 11 is a particle binder, the gaps between particles constitute the micropores, and the dimensions of the micropores are determined by the gaps between particles in the media segment 11.

[0071] Note that airway openings 11a are holes in a macroscopic sense and can be identified with the naked eye, while micropores are holes in a microscopic sense and cannot be identified with the naked eye.

[0072] The airway holes 11a and micropores can increase the surface area of ​​the medium segment 11, which facilitates heat transfer and improves heating efficiency. The aerosol-generating substrate in the medium segment 11 receives heat and releases aerosols, which are transported to the functional segment 12 under the action of negative pressure generated by user inhalation. The airway holes 11a and micropores can reduce user inhalation resistance and improve the user experience, and the undesirable effect of condensed aerosols remaining in the medium segment 11 and affecting airflow is reduced.

[0073] In some embodiments, referring to Figures 1 to 3 and Figures 6 to 12, a first air intake port 10a is provided in the first covered section 101, and the first air intake port 10a penetrates the side wall of the first covered section 101.

[0074] In this embodiment, by processing the first covered section 101 to provide a first air intake port 10a, air from the external environment enters the air intake channel 12a of the functional segment 12 from the side of the first covered section 101, which is convenient for aerosol extraction.

[0075] The number of first air intake ports 10a may be one or two or more.

[0076] Furthermore, if the number of first air intake ports is too large, the air intake volume will be excessive, resulting in low suction resistance and a low aerosol content. Conversely, if the number of first air intake ports is too small, the air intake volume will be insufficient, resulting in high suction resistance and a low aerosol content, both of which will affect the user experience.

[0077] In some embodiments, the number of first air intake ports 10a is 4 to 30, for example, 4, 5, 7, 8, 10, 13, 17, 20, 25, 28, 30, etc.

[0078] In this embodiment, the number of first air intake ports 10a is appropriate; it is neither too many nor too few, the suction resistance is appropriate, the amount of aerosol inhaled by the user is appropriate, and the user experience is improved.

[0079] In some other embodiments, referring to Figures 4 and 5, a groove 12c is provided on the circumferential surface of the functional segment 12, the groove 12c penetrates at least one end of the functional segment 12 closer to the medium segment 11, and the other end of the functional segment 12 further from the medium segment 11 protrudes from the first covering section 101, the gap between the end of the first covering section 101 and the functional segment 12 defines the first intake port 10a, and the inner wall of the first covering section 101 and the groove wall of the groove 12c define the intake channel 12a.

[0080] In this embodiment, the first air intake port 10a is defined by the compounding gap between the first coating section 101 and the functional segment 12, eliminating the need for additional processing of the first coating section 101, thereby reducing the manufacturing requirements for the coating layer 10 and simplifying the processing steps for the aerosol product 1. Air from the external environment enters through the gap between the end of the first coating section 101 and the functional segment 12 and flows out through the exhaust channel 12b accompanied by aerosols.

[0081] As can be understood, in this embodiment, one end of the functional segment 12 furthest from the medium segment 11 protrudes from the coating layer 10 and is exposed outside the coating layer 10. During suction, the user can directly place the portion of the functional segment 12 exposed outside the coating layer 10 into their mouth and inhale the aerosol, making aerosol inhalation more convenient and improving the user experience.

[0082] Naturally, in some examples, a first air intake port 10a is provided at a position corresponding to the groove 12c of the first covering section 101. In this embodiment, the first covering section 101 covers the entire circumferential outer surface of the functional segment 12, and the first air intake port 10a can penetrate the side wall corresponding to the groove 12c of the first covering section 101. Air from the external environment enters the groove 12c through the first air intake port 10a, thereby entering the media segment 11, entraining aerosols, and flowing out from the aerosol product 1 for use by the user.

[0083] As can be understood, in this embodiment, the fact that the groove 12c penetrates at least one end of the functional segment 12 on the side closer to the media segment 11 does not mean that the groove 12c penetrates only one end of the functional segment 12 on the side closer to the media segment 11, or that the groove 12c penetrates one end of the functional segment 12 on the side closer to the media segment 11 and also penetrates the other end of the functional segment on the side further from the media segment, i.e., the groove 12c penetrates both ends of the functional segment 12 along its longitudinal direction.

[0084] Referring to Figure 5, the groove 12c and the airway opening 11a overlap at least partially, so that air from the external environment can enter through the first inlet 10a and then quickly flow into the airway opening 11a, which is convenient for improving the efficiency of aerosol extraction.

[0085] In some embodiments, referring to Figures 2, 3, and 5, the functional segment 12 has one or more central airways 12d, one or more central airways 12d that penetrate the functional segment 12 along the longitudinal direction, and the central airways 12d at least partially overlap the airway openings 11a. That is, the central airways 12d and the airway openings 11a are at least partially connected, in this way aerosols can be rapidly extracted, increasing the efficiency of aerosol extraction and improving the user experience.

[0086] In some embodiments, referring to Figures 6 to 12, the functional segment 12 has a hollow tubular structure and has an inner wall surface 12f and an outer wall surface 12e, the inner wall surface 12f partitions a hollow space 12g, a second air intake port 12h is provided on the side wall of the functional segment 12, the second air intake port 12h penetrates at least the outer wall surface 12e and is connected to the first air intake port 10a.

[0087] In other words, air from the external environment passes through the first intake port 10a and then directly enters the functional segment 12 through the second intake port 12h, where it extracts aerosols and can flow out from the hollow space 12g accompanied by the aerosols. The hollow space 12g extends the aerosol flow path and flow area, thereby slowing down the aerosol flow velocity, achieving a cooling effect, and making the operating temperature of the aerosols more appropriate.

[0088] The fact that the second air intake port 12h penetrates at least the outer wall surface 12e does not mean that the second air intake port 12h penetrates only the outer wall surface 12e, or that the second air intake port 12h penetrates both the outer wall surface 12e and the inner wall surface 12f.

[0089] In some embodiments, referring to Figure 8, the structure between the inner wall surface 12f and the outer wall surface 12e is a solid structure, and the second air intake port 12h penetrates both the inner wall surface 12f and the outer wall surface 12e.

[0090] Furthermore, the solid structure may be a solid cellulose acetate 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 cellulose acetate tow. In this case, the functional segment 12 is a hollow cellulose acetate structure, with gaps between the cellulose acetate tow to form an airflow channel. Air from the external environment can enter the hollow space 12g through the second air intake 12h, move toward the medium segment 11, and carry aerosols out from the functional segment 12. Alternatively, air from the external environment can also flow directly from the hollow space 12g to the functional segment 12 through the second air intake 12h, carrying aerosols in the airflow channel.

[0091] The solid structure may further be a tubular structure without internal airflow channels, such as a paper tube or an aluminum foil tube; that is, the functional segment 12 is a hollow paper tube structure or a hollow aluminum foil paper tube structure. Air from the external environment enters the hollow space 12g through the second air intake 12h, moves toward the medium segment 11, entrains the aerosol, and flows into the functional segment 12. The hollow paper tube structure and the hollow aluminum foil paper tube structure are lightweight, which is convenient for reducing the overall weight of the aerosol product 1, and their hollow region can be used to lower the temperature of the aerosol. Furthermore, the hollow paper tube structure and the hollow aluminum foil tube structure have good heat resistance, are less likely to deform when heated, and can still maintain their shape even after heat conduction, thereby increasing the structural stability of the aerosol product 1. For example, referring to Figure 8, the functional segment 12 is a hollow paper tube structure.

[0092] Naturally, the functional segment 12 may also be a hollow silicone structure, a hollow PET (polyethylene glycol terephthalate) structure, etc., and is not particularly limited here. In this embodiment, the second air intake 12h penetrates both the outer wall surface 12e and the inner wall surface 12f, and air from the external environment enters through the first air intake 10a and the second air intake 12h, extracts aerosols, and flows out from the hollow space 12g.

[0093] To be understood, cellulose acetate refers to cellulose acetate, also known as cellulose acetate or cellulose acetate, and is a type of chemically modified polymer compound obtained by esterifying the hydroxyl groups in cellulose molecules with acetic acid. It includes diacetate fibers and triacetate fibers and has good acid-alkali resistance and organic solvent resistance.

[0094] In some embodiments, referring to Figure 9, there is a channel 12i between the inner wall surface 12f and the outer wall surface 12e that extends longitudinally and penetrates at least one end of the functional segment 12, and the second air intake port 12h communicates with the channel 12i. As can be seen, in this embodiment, the functional segment 12 may be a hollow corrugated pipe structure, a porous structure, etc. For example, referring to Figure 6, the functional segment 12 is a hollow corrugated pipe structure, and the cross-section of the region between the inner and outer walls of the hollow corrugated pipe is generally wavy.

[0095] The method of communication between the second air intake port 12h and channel 12i is not limited.

[0096] For example, in some embodiments, referring to Figure 9, the second air intake 12h passes only through the outer wall surface 12e, that is, the second air intake 12h does not pass through the inner wall surface 12f, and air from the external environment enters the channel 12i through the first air intake 10a and the second air intake 12h, thereby entering the medium segment 11, extracting aerosols and flowing out from the hollow space 12g. In this embodiment, air from the external environment extracts aerosols through only one airflow channel, which is convenient for uniform aerosol extraction and also convenient for reducing the temperature of the aerosols.

[0097] In some other embodiments, referring to Figure 7, the second intake port 12h passes through the channel 12i and penetrates the inner wall surface 12f.

[0098] In this embodiment, the second air intake port 12h penetrates both the outer wall surface 12e and the inner wall surface 12f. In this case, air from the external environment can enter the hollow space 12g via the first air intake port 10a and the second air intake port 12h to extract aerosols, and can also enter the channel 12i via the first air intake port 10a and the second air intake port 12h to extract aerosols and discharge out through the exhaust channel 12b. In other words, in this embodiment, the air from the external environment can have two airflow channels, and in this way, more aerosols can be extracted within a unit time, which is convenient for improving the aerosol extraction efficiency.

[0099] Furthermore, the number of second air intake ports 12h is not limited; there may be one or two or more.

[0100] In some examples, aromatic substances are provided within the functional segment 12, thereby enriching the flavor of the aerosol and improving the user experience.

[0101] In some embodiments, as shown in Figure 3, the structure of the functional segment 12 and the locking member 13 are identical and are arranged symmetrically with respect to the medium segment 11. In this way, when the user uses the aerosol product 1, there is no need to distinguish between the functional segment 12 and the locking member 13, and they can be attached to the heating element and mixed together, increasing the convenience of use of the aerosol product 1. Furthermore, because the functional segment 12 and the locking member 13 are arranged symmetrically with respect to the medium segment 11, the aesthetic appearance of the aerosol product 1 can also be improved.

[0102] The specific structure of functional segment 12 is not limited.

[0103] For example, referring to Figures 1 to 7 in some examples, 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 filtration segment 123. That is, the functional segment 12 may include only the cooling segment 121, the functional segment 12 may include only the support segment 122, or the functional segment 12 may include only the filtration segment 123.

[0104] In several other examples, referring to Figures 8 to 9 and Figures 11 to 12, the functional segment 12 is a multi-stage combination structure, and the multi-stage combination structure includes at least two of the cooling segment 121, the support segment 122, and the filtration segment 123, that is, the functional segment 12 may include two of the cooling segment 121, the support segment 122, and the filtration segment 123, or it may include three of the cooling segment 121, the support segment 122, and the filtration segment 123.

[0105] For example, in some embodiments, referring to Figure 9, the functional segment 12 includes a cooling segment 121 and a filtration segment 123, the filtration segment 123 is located at one end of the cooling segment 121 furthest from the medium segment 11, and an intake channel 12a is provided in the cooling segment 121. The aerosol flows out of the aerosol product 1 through the cooling segment 121 and the filtration segment 123, the cooling segment 121 lowers the temperature of the aerosol to make the aerosol's operating temperature more appropriate, and the filtration segment 123 filters out impurities and harmful components trapped in the aerosol to improve the user experience.

[0106] In some other embodiments, the functional segment 12 includes a cooling segment 121, a support segment 122, and a filtration segment 123, wherein the cooling segment 121 and the support segment 122 are located between the medium segment 11 and the filtration segment 123.

[0107] The cooling segment 121 can be provided between the support segment 122 and the filtration segment 123, as shown in Figures 11 and 12. Specifically, the aerosol flows out of the aerosol product 1 through the support segment 122, the cooling segment 121, and the filtration segment 123. The support segment 122 connects and supports the media segments 11 and the cooling segment 121 on both sides and can assist in temperature reduction. The cooling segment 121 lowers the temperature of the aerosol, and the filtration segment 123 filters out impurities and large particulate matter trapped in the aerosol, improving the user experience.

[0108] The cooling segment 121 can also be placed between the medium segment 11 and the support segment 122. That is, the aerosol flows out of the aerosol product 1 through the cooling segment 121, the support segment 122, and the filtration segment 123. The cooling segment 121 lowers the temperature of the aerosol, the support segment 122 connects and supports the cooling segments 121 and the filtration segment 123 on both sides and can assist in the temperature reduction, and the filtration segment 123 filters out impurities and large particulate matter trapped in the aerosol, improving the user experience.

[0109] The structure of the cooling segment 121, the support segment 122, and the filtration segment 123 is not limited.

[0110] The cooling segment 121 may have a hollow tubular structure, such as a hollow cellulose acetate structure, a hollow aluminum foil paper tube structure, a hollow silicone structure, or a hollow PET (polyethylene glycol terephthalate) structure.

[0111] The support segment 122 may be a hollow tubular structure, a hollow cellulose acetate structure, a hollow aluminum foil paper tube structure, a hollow silicone structure, a hollow PET (polyethylene glycol terephthalate) structure, etc. The filtration segment 123 may be a solid cellulose acetate structure, which on the one hand can filter out impurities or harmful substances trapped in the aerosol, adsorb condensed liquid or large droplets formed by the aerosol condensation, keep the aerosol dry, and improve the user experience, and on the other hand can adjust the suction resistance and make the aerosol content generated per unit time more rational.

[0112] In some embodiments, referring to Figure 10, the media segment 11 and the functional segment 12 are spaced apart to form a first cavity 101a, which has a relatively large space that can increase the contact area with the aerosol, is convenient for lowering the aerosol temperature, and can also reduce the possibility of aerosol accumulating on the contact surface between the functional segment 12 and the media segment 11, improving the aerosol extraction rate and also being convenient for aerosol storage.

[0113] To be understood, the first air intake port 10a may penetrate the portion of the first covering section 101 corresponding to the first cavity 101a, or it may penetrate the portion of the first covering section 101 corresponding to the functional segment 12. For example, referring to Figure 10, the first air intake port 10a can penetrate the portion of the first covering section 101 corresponding to the first cavity 101a.

[0114] In some embodiments, at least two combination structures in a multi-stage combination structure are spaced apart to form a second cavity 101b. In this way, on the one hand, it is convenient for air from the external environment to enter and convenient for aerosol extraction, reducing the possibility of aerosol deposition on the contact surface of two adjacent combination structures, and on the other hand, the temperature of the aerosol can be lowered, making the operating temperature of the aerosol more appropriate.

[0115] To be understood, the first air intake port 10a may penetrate the portion of the first covering section 101 corresponding to the second cavity 101b, or the first air intake port 10a may penetrate the portion of the first covering section 101 corresponding to the functional segment 12.

[0116] As can be understood, the arrangement of at least two combined structures spaced apart to form the second cavity 101b includes a variety of situations.

[0117] In the first type, the cooling segment 121 and the support segment 122 are provided with a gap between them to form the second cavity 101b.

[0118] In the second type, the cooling segment 121 and the filtration segment 123 are spaced apart to form the second cavity 101b.

[0119] In the third type, the support segment 122 and the filtration segment 123 are spaced apart to form the second cavity 101b.

[0120] For example, referring to Figure 12, the functional segment 12 includes a cooling segment 121, a support segment 122, and a filtration segment 123. The cooling segment 121 and the filtration segment 123 are spaced apart to form a second cavity 101b, which has a relatively large space that can increase the contact area with the aerosol, which is convenient for lowering the temperature of the aerosol, and can also reduce the possibility of aerosol accumulating on the contact surface between the cooling segment 121 and the filtration segment 123, improving the aerosol extraction rate and also being convenient for aerosol storage.

[0121] As can be understood, the first covering section 101 may have only the first cavity 101a, only the second cavity 101b, or both the first cavity 101a and the second cavity 101b.

[0122] Naturally, in several other embodiments, referring to Figures 2, 3, 5, 7 to 9, both ends of the media segment 11 along its longitudinal direction are in contact with the functional segment 12 and the locking member 13, respectively. That is, there is no void between the media segment 11 and the functional segment 12, and there is no void between the media segment 11 and the locking member 13. Both ends of the media segment 11 along its longitudinal direction can abut against the functional segment 12 and the locking member 13, respectively. In this way, it is convenient to increase the structural stability of the media segment 11, reduce the difficulty of contact between the media segment 11, the functional segment 12, and the locking member 13, and facilitate assembly.

[0123] The structure of the locking member 13 is not limited.

[0124] In some examples, the locking member 13 is one of the following: a thin film structure with ventilation function, a mesh screen structure, a solid cellulose acetate structure, a hollow tubular structure, a structure formed by providing a partition member within a hollow tubular structure, or an extruded porous structure.

[0125] If the locking member 13 is a thin film structure with a ventilation function, as shown in Figure 7, the thin film structure has many micropores. On the one hand, this reduces the possibility of the medium segment 11 detaching from the coating layer 10 after heating, adsorbs the condensate formed by the condensation of aerosols, and reduces the possibility of the condensate detaching from the coating layer 10 and contaminating the aerosol generator. On the other hand, it reduces the length of the aerosol product 1 along its longitudinal direction, making the structure of the aerosol product 1 more compact, or it allows for an increase in the length of the medium segment 11 without changing the length of the aerosol product 1, thereby increasing the aerosol content.

[0126] As is understood, micropores are holes in a microscopic sense, meaning they cannot be directly identified with the naked eye.

[0127] If the locking member 13 has a mesh screen structure, as shown in Figure 11, the dimensions of the locking member 13 along its longitudinal direction are very small, and the locking member 13 can be made up of a mixture of several intersecting thread-like structures, which is advantageous in reducing the overall dimensions of the aerosol product 1, on the basis of achieving locking engagement with the medium segment 11 after heating and shrinking, and making the structure more compact.

[0128] If the locking member 13 has a solid cellulose acetate structure, as shown in Figure 9, on the one hand, it can adsorb the condensate formed by the condensation of aerosols, reducing the possibility of the condensate escaping from the coating layer 10 and causing contamination of the aerosol generator, making cleaning the aerosol generator convenient, and on the other hand, it can increase the suction resistance, making the aerosol content generated per unit time more reasonable and improving the user experience.

[0129] If the locking member 13 has a hollow tubular structure, as shown in Figure 3, on the one hand, the possibility of the medium segment 11 escaping from the coating layer 10 after heat shrinkage can be reduced, and on the other hand, its hollow structure is advantageous for sufficient heat absorption by the medium segment 11 and convenient for aerosol extraction. The hollow tubular structure may be a hollow paper tube, a hollow aluminum foil paper tube, a hollow cellulose acetate structure, a hollow PET (polyethylene glycol terephthalate) structure, a hollow corrugated structure, a hollow silicone structure, etc.

[0130] If the locking member 13 is formed by providing a partition member within a hollow tubular structure, the partition member can further enhance the locking capacity of the locking member 13 and provide sufficient support for the media segment 11.

[0131] If the locking member 13 is an extruded porous structure, as shown in Figure 10, the aerosol condensate is also absorbed into the porous structure, increasing the locking reliability of the locking member 13. In some examples, if the locking member 13 is an extruded porous structure, the porous structure comes into contact with the airway pores 11a, which is advantageous for heat absorption of the medium segment 11 and convenient for aerosol extraction.

[0132] Naturally, in some other embodiments, the locking member 13 may be an injection-molded porous structure or a die-cast porous structure.

[0133] In some examples, the locking member 13 may further include an aerosol-generating substrate, which can further participate in heating, provide aerosols, and improve aerosol content, in a manner that prevents the medium segment 11 from escaping from the coating layer 10 after heat deformation.

[0134] The molding method for the locking member 13 is not limited; for example, the locking member 13 may be an integrally molded structure, which is simple in its molding method and allows for a fast molding speed.

[0135] The materials of the cooling segment 121, support segment 122, and filtration segment 123 are not limited. For example, the materials of the cooling segment 121, support segment 122, and filtration segment 123 include, but are not limited to, one or more combinations of PE (polyethylene), PLA (Polylactic acid, also called polylactide), PBAT (Poly(butylene adipate-co-terephthalate)), PP (Polypropylene), cellulose acetate, and propylene fiber materials.

[0136] As can be understood, the materials of the support segment 122, the cooling segment 121, and the filtration segment 123 may be the same or different.

[0137] In some embodiments, the cross-sections of the locking member 13, the media segment 11, and the functional segment 12 are identical, and their cross-sectional dimensions are also identical. This is advantageous for assembly between the locking member 13, the media segment 11, and the functional segment 12, and also relaxes the dimensional requirements for the coating layer 10, thereby improving the assembly reliability of the aerosol product 1.

[0138] The molding method for the locking member 13 and the functional segment 12 is not limited. The locking member 13 and the functional segment 12 can be integrally molded by extrusion molding, injection molding, or die casting. The cross-sectional shape of the aerosol product 1 is not limited.

[0139] In some examples, the cross-sectional shape of aerosol product 1 is generally circular, meaning the aerosol product 1 as a whole has a generally columnar structure. In other examples, the cross-section of aerosol product 1 is generally rectangular, meaning the aerosol product 1 as a whole has a generally rectangular prism shape.

[0140] In some embodiments, referring to Figures 1 to 3 and Figures 6 to 12, the functional segment 12, the medium segment 11, and the locking member 13 are cylindrical bodies with the same outer diameter and arranged coaxially, and their longitudinal direction is the axial direction of the functional segment 12, the medium segment 11, and the locking member 13.

[0141] The functional segment 12, the medium segment 11, and the locking member 13 are in contact along the axial direction, the formulation of each stage is simple, and the difficulty of coating the outside of each stage with the coating layer 10 is reduced, thereby reducing the difficulty of manufacturing the aerosol product 1.

[0142] The following briefly describes the airflow method by combining the nine embodiments shown in the drawings.

[0143] First embodiment: Referring to Figures 1 and 2, the functional segment 12 has a single-stage structure and has a hollow space 12g. The first air intake 10a penetrates the side wall of the first covering section 101, and the second air intake 12h penetrates the inner wall surface 12f and the outer wall surface 12e of the functional segment 12. Air from the external environment enters the hollow space 12g through the first air intake 10a and the second air intake 12h, thereby entering the inside of the medium segment 11 and diffusing.

[0144] The media segment 11 has micropores inside, and these micropores are at least partially in communication with each other and also in communication with the airway opening 11a. Aerosols generated by the media surrounding the airway opening 11a (i.e., the media segment 11 exposed to the airway opening 11a) enter the airway opening 11a directly, while aerosols generated by other parts of the media segment 11 (i.e., the media segment 11 not exposed to the airway opening 11a) can collect in the airway opening 11a through the micropores. In this way, during the suction process, air entering from the second inhalation port 12h through the hollow space 12g entrains the aerosols collected in the airway opening 11a, flows out of the aerosol product 1 through the hollow space 12g, and can enter the user's mouth.

[0145] Second example: Referring to Figure 3, the functional segment 12 has a single-stage structure, and the structure of the functional segment 12 and the locking member 13 are identical. The inner wall surface 12f of the functional segment 12 partitions the hollow space 12g, the first air intake 10a penetrates the side wall of the first covering section 101, and the second air intake 12h penetrates the outer wall surface 12e and the inner wall surface 12f of the functional segment 12. Air from the external environment enters the hollow space 12g through the first air intake 10a and the second air intake 12h, thereby entering the inside of the medium segment 11 and diffusing.

[0146] The media segment 11 has micropores inside, and these micropores are at least partially in communication with each other and also in communication with the airway opening 11a. Aerosols generated by the media surrounding the airway opening 11a (i.e., the media segment 11 exposed to the airway opening 11a) enter the airway opening 11a directly, while aerosols generated by other parts of the media segment 11 (i.e., the media segment 11 not exposed to the airway opening 11a) can collect in the airway opening 11a through the micropores. In this way, during the suction process, air entering from the second inhalation port 12h through the hollow space 12g entrains the aerosols collected in the airway opening 11a, flows out of the aerosol product 1 through the hollow space 12g, and can enter the user's mouth.

[0147] Third example: Referring to Figures 4 and 5, the functional segment 12 has a single-stage structure, the circumferential outer surface of the functional segment 12 has a groove 12c, the inner wall surface 12f of the functional segment 12 partitions a hollow space 12g, the gap between the end of the first covering section 101 and the functional segment 12 defines the first air intake 10a, at least a portion of the groove 12c overlaps with the airway hole 11a, and air from the external environment enters the groove 12c through the first air intake 10a, thereby entering the inside of the medium segment 11 and diffusing.

[0148] The media segment 11 has micropores inside, and these micropores are at least partially in communication with each other and also in communication with the airway hole 11a. Aerosols generated by the media surrounding the airway hole 11a (i.e., the media segment 11 exposed to the airway hole 11a) enter the airway hole 11a directly, while aerosols generated by other parts of the media segment 11 (i.e., the media segment 11 not exposed to the airway hole 11a) can collect in the airway hole 11a through the micropores. In this way, during the suction process, air entering from the first inhalation port 10a through the groove 12c entrains the aerosols collected in the airway hole 11a, flows out of the aerosol product 1 through the hollow space 12g, and can enter the user's mouth.

[0149] Fourth embodiment: Referring to Figures 6 and 7, the functional segment 12 has a single-stage structure, the inner wall surface 12f of the functional segment 12 partitions a hollow space 12g, the first air intake 10a penetrates the side wall of the first covering section 101, there is a channel 12i between the inner wall surface 12f and the outer wall surface 12e, and the second air intake 12h penetrates the inner and outer walls of the functional segment 12, so that air from the external environment has two paths to enter the medium segment 11.

[0150] First pathway: Air from the external environment enters channel 12i through the second intake port 12h, and then enters the inside of the medium segment 11 via channel 12i, where it can diffuse.

[0151] Second pathway: Air from the external environment enters the hollow space 12g through the second air intake 12h, and then enters the inside of the medium segment 11 via the hollow space 12g, where it can diffuse.

[0152] The media segment 11 has micropores inside, and these micropores are at least partially in communication with each other and also in communication with the airway opening 11a. Aerosols generated by the media surrounding the airway opening 11a (i.e., the media segment 11 exposed to the airway opening 11a) enter the airway opening 11a directly, while aerosols generated by other parts of the media segment 11 (i.e., the media segment 11 not exposed to the airway opening 11a) can collect in the airway opening 11a through the micropores. In this way, during the suction process, air entering the media segment 11 through the two aforementioned pathways can carry the collected aerosols, flow out of the aerosol product 1 through the hollow space 12g, and enter the user's mouth.

[0153] Fifth example: Referring to Figure 8, the functional segment 12 has a multi-stage combination structure and includes a cooling segment 121 and a filtration segment 123. The second air intake 12h is provided in the cooling segment 121, and air from the external environment enters the hollow space 12g through the second air intake 12h, thereby entering the inside of the medium segment 11 and diffusing. The air that enters the medium segment 11, along with the collected aerosols, flows out of the aerosol product 1 via the cooling segment 121 and the filtration segment 123, and can enter the user's mouth.

[0154] Sixth embodiment: Referring to Figure 9, the functional segment 12 has a multi-stage combination structure and includes a cooling segment 121 and a filtration segment 123. The second air intake 12h is provided in the cooling segment 121, and air from the external environment enters the channel 12i through the second air intake 12h, thereby entering the inside of the medium segment 11 and diffusing. The air that enters the medium segment 11, along with the collected aerosols, flows out of the aerosol product 1 via the cooling segment 121 and the filtration segment 123, and can enter the user's mouth.

[0155] Seventh example: Referring to Figure 10, the functional segment 12 has a single-stage structure, the inner wall surface 12f of the functional segment 12 partitions a hollow space 12g, the functional segment 12 and the media segment 11 are spaced apart to form a first cavity 101a, the first air intake 10a penetrates the side wall of the first covering section 101 corresponding to the first cavity 101a, air from the external environment enters the first cavity 101a through the first air intake 10a and can diffuse inside the media segment 11.

[0156] The media segment 11 has micropores inside, and these micropores are at least partially in communication with each other and also in communication with the airway hole 11a. Aerosols generated in the media segment 11 surrounding the airway hole 11a (i.e., the media segment 11 exposed to the airway hole 11a) enter the airway hole 11a directly, while aerosols generated in other parts of the media segment 11 (i.e., the media segment 11 not exposed to the airway hole 11a) can collect in the airway hole 11a through the micropores. In this way, during the suction process, air entering the media segment 11 from the first inhalation port 10a through the first cavity 101a entrains the collected aerosols and flows out of the aerosol product 1 through the first cavity 101a and the hollow space 12g, and can enter the user's mouth.

[0157] Eighth example: Referring to Figure 11, the functional segment 12 has a multi-stage combination structure and includes a cooling segment 121, a support segment 122, and a filtration segment 123. Both ends of the cooling segment 121 along its longitudinal direction are in contact with the support segment 122 and the filtration segment 123, respectively. A second air intake port 12h is provided in the cooling segment 121, allowing air from the external environment to enter the media segment 11 through the second air intake port 12h and diffuse. The air that enters the media segment 11, along with the collected aerosols, flows out of the aerosol product 1 through the support segment 122, the cooling segment 121, and the filtration segment 123, and can enter the user's mouth.

[0158] Ninth example: Referring to Figure 12, the functional segment 12 has a multi-stage combination structure and includes a cooling segment 121, a support segment 122, and a filtration segment 123. The cooling segment 121 is located between the support segment 122 and the filtration segment 123, and the support segment 122 and the filtration segment 123 are spaced apart to form a second cavity 101b. A second air intake port 12h is provided in the cooling segment 121, allowing air from the external environment to enter the media segment 11 through the second air intake port 12h and diffuse. The air that enters the media segment 11 entrains the collected aerosols and flows out of the aerosol product 1 through the support segment 122, cooling segment 121, second cavity 101b, and filtration segment 123, and can enter the user's mouth.
