Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and more specifically, to an aerosol generation product and an aerosol generation system. Background Technology

[0002] An aerosol generating device is a small device that uses heat-not-burning (HNB) technology to act on an aerosol generating product and produce aerosols. In related technologies, the aerosol generating product has an inlet channel for external gas to flow into the medium within the aerosol generating product, enabling the medium to generate aerosols when heated. Generally, the inlet channel causes gas to accumulate in the central region of the medium. Therefore, when the aerosol generating device uses a peripheral heating method to heat the aerosol generating product, the inlet channel cannot precisely match the initial carbonization zone of the medium (the outermost ring of the medium). This results in the generated aerosol not being effectively carried out, leading to a smaller amount of aerosol that can be drawn out, affecting the smoking experience. Utility Model Content

[0003] The embodiments of this application provide an aerosol generating article and an aerosol generating system to solve at least one of the above-mentioned technical problems.

[0004] The aerosol generating article according to embodiments of this application includes a body, a medium, and a guide member. The body has a receiving cavity. The medium is disposed within the receiving cavity and is used to generate an aerosol. The guide member is disposed within the receiving cavity and is adjacent to the medium along the length direction of the aerosol generating article. The guide member includes a limiting portion and a guiding portion surrounding the limiting portion. The guiding portion has an air inlet channel for allowing external gas to flow to the medium. The air permeability of the guiding portion is greater than the air permeability of the limiting portion.

[0005] In some embodiments, the guide portion has a porous and loose structure, and the air intake channel includes pores provided in the guide portion.

[0006] In some embodiments, the limiting portion is a dense structure.

[0007] In some embodiments, the limiting part has a porous and loose structure, and the porosity of the limiting part is less than that of the guiding part.

[0008] In some embodiments, the aerosol generating article further includes a cooling element disposed within the accommodating cavity and located on the side of the medium opposite to the guide member, the cooling element being used to cool the aerosol.

[0009] In some embodiments, the cooling component includes a first loading portion, a second loading portion, and a plurality of support portions. The first loading portion has a first channel along the length direction. The second loading portion surrounds the first loading portion and is connected to the body. The plurality of support portions are spaced apart between the first loading portion and the second loading portion, and the first loading portion, the second loading portion, and the support portions together form a second channel along the length direction.

[0010] In some embodiments, the first loading part, the second loading part, and the support part together form a third channel perpendicular to the length direction, one end of the third channel being connected to the first channel and the other end being connected to the outside gas.

[0011] In some embodiments, the body includes a first end face and a second end face facing away from each other, the guide member is closer to the first end face than the second end face, and at least a portion of the guide portion is disposed around the outer peripheral wall of the limiting portion.

[0012] In some embodiments, the outer peripheral wall of the limiting portion is perpendicular to the first end face.

[0013] In some embodiments, the ratio of the cross-sectional area of ​​the limiting portion to the cross-sectional area of ​​the medium is 0.2-0.8.

[0014] In some embodiments, the outer peripheral wall of the limiting portion is inclined relative to the first end face, and the slope of the outer peripheral wall of the limiting portion remains unchanged.

[0015] In some embodiments, the outer peripheral wall of the limiting portion is inclined relative to the first end face, and the slope of the outer peripheral wall of the limiting portion gradually decreases.

[0016] In some embodiments, the limiting portion includes a cylindrical first sub-portion and a second sub-portion. The first sub-portion includes a first end and a second end opposite to each other, with the first end of the first sub-portion closer to the first end face than the second end of the first sub-portion.

The guide member includes a limiting part and a guide part surrounding the limiting part. The guide part is provided with an air inlet channel for external gas to flow to the medium. The air permeability of the guide part is greater than that of the limiting part. As a result, most of the external gas can flow to the outer ring of the medium. When the aerosol generating device heats the aerosol generating article by means of peripheral heating, the air inlet channel can be precisely matched with the initial carbonization area of ​​the medium (i.e., the outer ring of the medium), thereby ensuring that the generated aerosol is effectively carried out, increasing the amount of aerosol that can be drawn out, and improving the drawing experience.

[0037] In related technologies, aerosol generating products have an air inlet channel for allowing external gas to flow into the medium within the aerosol generating product, enabling aerosol generation when the medium is heated. Generally, the air inlet channel causes gas to accumulate in the central region of the medium. Therefore, when the aerosol generating device uses peripheral heating to heat the aerosol generating product, the air inlet channel cannot precisely match the initial carbonization zone of the medium (the outermost ring of the medium). This results in the generated aerosol not being effectively carried out, leading to a smaller amount of aerosol that can be drawn out, affecting the smoking experience. To solve the above problem, please refer to [link to relevant documentation]. Figure 1 This application provides an aerosol generating article 100 and an aerosol generating system 1000.

[0038] Please see Figure 1The aerosol generation system 1000 of this application includes an aerosol generation article 100. Further, in some embodiments, the aerosol generation system 1000 also includes an aerosol generation device 300, which includes a housing 310 and a heating element 330. At least a portion of the aerosol generation article 100 is disposed in the housing 310, and the heating element 330 is disposed in the housing 310, surrounding the outside of the medium 30 and used to heat the medium 30.

[0039] It is understood that the aerosol generating article 100 is a structure capable of generating aerosols when heated. The shape and size of the aerosol generating article 100 can be designed according to the type of aerosol generating device 300 of the aerosol generating system 1000 or specific application requirements.

[0040] The housing 310 is a structure in the aerosol generating device 300 that houses and protects the heating element 330 and other devices. The materials used for the housing 310 include, but are not limited to, plastics, aluminum alloys, copper, iron, steel, and carbon fiber composites. In one example, the housing 310 can be made of plastic, making it lighter and thus contributing to the portability of the aerosol generating device 300. In another example, the housing 310 can be made of a high-temperature resistant material, preventing damage (such as deformation) caused by heat and ensuring the stability and reliability of the aerosol generating device 300. High-temperature resistant materials include, but are not limited to, polyetheretherketone (PEEK), high-melting-point metals, and high-temperature ceramics.

[0041] The heating element 330 is a structure in the aerosol generating apparatus 300 capable of generating heat energy or transferring heat energy to other parts. In some embodiments, the heating element 330 can directly convert other forms of energy such as electrical energy, chemical energy, and solar energy into heat energy, and conduct it to other parts that need to be heated via heat transfer. In other embodiments, the heating element 330 emits other forms of energy such as electromagnetic waves, lasers, infrared light, or thermal radiation that can directly act on the surface of the part to be heated, so as to raise the temperature of the area receiving the electromagnetic waves, lasers, infrared light, or thermal radiation. In some embodiments of this application, the heating method of the heating element 330 can be peripheral heating, that is, the heat from the heating element 330 can be preferentially transferred to the outermost layer of the aerosol generating article 100 through heat conduction or radiation.

[0042] Since the aerosol generation system 1000 in this embodiment includes an aerosol generation article 100, it is understood that the aerosol generation system 1000 has at least the same beneficial effects as the aerosol generation article 100. Therefore, for the beneficial effects of the aerosol generation system 1000, please refer to the beneficial effects of the aerosol generation article 100 described below.

[0043] Please see Figure 1 and combined Figure 2 , Figure 4 , Figure 5 or Figure 6 The aerosol generating article 100 of this application includes a body 10, a medium 30, and a guide member 50. The body 10 has a receiving cavity. The medium 30 is disposed in the receiving cavity and is used to generate aerosol. The guide member 50 is disposed in the receiving cavity and is adjacent to the medium 30 in the longitudinal direction X of the aerosol generating article 100. The guide member 50 includes a limiting part 53 and a guiding part 51 surrounding the limiting part 53. The guiding part 51 has an air inlet channel 511 for allowing external gas to flow to the medium 30. The air permeability of the guiding part 51 is greater than the air permeability of the limiting part 53.

[0044] It is understood that the body 10 is a structure in the aerosol generating article 100 capable of housing components other than the body 10. Components other than the body 10, as used herein, include, but are not limited to, the medium 30 and the guide 50. The outer contour shape of the cross-section of the body 10 includes, but is not limited to, circles, squares, triangles, and rhombuses. The material of the body 10 includes, but is not limited to, plastics, aluminum alloys, copper, iron, steel, and carbon fiber composites. For example, the body 10 may be made of a high-temperature resistant material to prevent damage (e.g., deformation) caused by heat, thus ensuring the stability and reliability of the aerosol generating article 100. High-temperature resistant materials include, but are not limited to, polyetheretherketone (PEEK), high-melting-point metals, and high-temperature ceramics. For ease of understanding, the following embodiments use a circular outer contour shape of the cross-section of the body 10 as an example.

[0045] Medium 30 is a processed element that can generate aerosols upon heating. Medium 30 can be in a fully solid or semi-solid state. When medium 30 is fully solid, it can be formed using processes such as rolling or slurry preparation. The cross-sectional shape of medium 30 includes, but is not limited to, regular or irregular shapes such as circles, ellipses, triangles, and squares. In this application, the cross-sectional shape of medium 30 includes circles. The aerosol can be visible or invisible and may include vapors (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor.

[0046] In some embodiments of this application, the medium 30 includes a first part 31 and a second part 33 that are in contact with each other. The first part 31 surrounds the outer peripheral wall 5301 of the second part 33. The guiding part 51 is at least opposite to the first part 31, and the limiting part 53 is opposite to the second part 33. The first part 31 and the second part 33 are an integral structure, that is, the first part 31 and the second part 33 are a single integral structure manufactured using an integral molding process. The first part 31 includes the outermost ring of the medium 30. That is, when the aerosol generating article 100 is drawn in, the heat generated by the heating element 330 can preferentially act on the first part 31, causing the first part 31 to be heated and carbonized to generate aerosol.

[0047] Specifically, in the length direction X of the aerosol generating article 100, the guide portion 51 is at least opposite to the first portion 31, that is, the projection of the guide portion 51 on the plane perpendicular to the length direction X of the aerosol generating article 100 coincides with the projection of the first portion 31 on the plane perpendicular to the length direction X of the aerosol generating article 100; in the length direction X of the aerosol generating article 100, the restricting portion 53 is opposite to the second portion 33, that is, the projection of the restricting portion 53 on the plane perpendicular to the length direction X of the aerosol generating article 100 coincides with the projection of the second portion 33 on the plane perpendicular to the length direction X of the aerosol generating article 100. Furthermore, since the air permeability of the guide section 51 is greater than that of the restriction section 53, when external gas flows to the medium 30 through the air inlet channel 511, most of the external gas can flow to the first section 31, thereby ensuring that the aerosol generated by the heating of the first section 31 is effectively carried out, increasing the amount of aerosol when the user takes the first or first few puffs, and improving the puffing experience.

[0048] In some embodiments, the air permeability of the restricting part 53 is 0, and the air permeability of the guiding part 51 is greater than that of the restricting part 53. This allows external gas to flow in a concentrated manner to the outer ring of the medium 30 (such as the first part 31), ensuring that the aerosol generated by the heating of the outer ring of the medium 30 can be effectively carried out, increasing the amount of aerosol that can be sucked up and improving the sucking experience.

[0049] In other embodiments, the permeability of the restricting portion 53 is not zero, and the permeability of the guiding portion 51 is greater than that of the restricting portion 53. This allows most of the external gas to flow to the outer ring of the medium 30, while a small amount of external gas flows to the inner ring of the outer ring of the medium 30 (such as the second portion 33). This ensures that the aerosol generated by heating the outer ring of the medium 30 can be effectively carried out, increasing the amount of aerosol that can be drawn out and improving the suction experience. For example, when the permeability of the restricting portion 53 is not zero, the permeability of the restricting portion 53 is less than one-tenth of the permeability of the medium 30.

[0050] In some embodiments, the guide portion 51 and the limiting portion 53 are an integral structure, that is, the guide portion 51 and the limiting portion 53 are a single structure manufactured using an integral molding process. In other embodiments, the guide portion 51 and the limiting portion 53 are separate structures, that is, the guide portion 51 and the limiting portion 53 are two different structures. The guide portion 51 and the limiting portion 53 can be joined together using either a detachable connection method or a non-detachable connection method. Detachable connection methods include, but are not limited to, bolt connections or snap-fit ​​connections; non-detachable connection methods include, but are not limited to, adhesive connections or welding.

[0051] In the aerosol generating article 100 of this application embodiment, in the length direction X of the aerosol generating article 100, the guide member 50 is adjacent to the medium 30. The guide member 50 includes a limiting part 53 and a guide part 51 surrounding the limiting part 53. The guide part 51 is provided with an air inlet channel 511, which is used to allow external gas to flow to the medium 30. The air permeability of the guide part 51 is greater than that of the limiting part 53. As a result, most of the external gas can flow to the outer ring of the medium 30 (such as the first part 31). When the aerosol generating device 300 heats the aerosol generating article 100 by means of peripheral heating, the air inlet channel 511 can be precisely matched with the initial carbonization area of ​​the medium 30 (i.e., the outer ring of the medium 30), thereby ensuring that the generated aerosol is effectively carried out, increasing the amount of aerosol that can be sucked up, and improving the sucking taste.

[0052] The aerosol-generated product 100 will be further described below with reference to the accompanying drawings.

[0053] Please see Figure 2 , Figure 4 , Figure 5 or Figure 6 In some embodiments, the guide portion 51 has a porous and loose structure, and the air intake channel 511 includes pores provided in the guide portion 51. It should be noted that in some embodiments, the porous and loose structure may include filter cotton, ethyl acetate, polyethylene terephthalate (PET), cellulose acetate, activated carbon, or polysaccharide materials, etc., and is not limited thereto.

[0054] Specifically, when the guide portion 51 has a porous structure, it has pores that allow external gas to enter the interior of the aerosol generating product 100 and come into contact with the medium 30. Therefore, the air inlet channel 511 includes pores provided in the guide portion 51. For example, the guide portion 51 is made of porous ceramic, which can be prepared by mixing ceramic slurry with a pore-forming agent and then sintering. The sintered ceramic body has a large number of pores, which are the air inlet channel 511 in this article.

[0055] In some embodiments, the limiting part 53 is a dense structure.

[0056] Specifically, in some embodiments, the restricting part 53 has a dense structure, that is, the restricting part 53 does not have micropores. This allows external gas to flow concentratedly to the first part 31 through the air inlet channel 511 of the guide part 51, ensuring that the aerosol generated by the heating of the first part 31 can be effectively carried out, increasing the amount of aerosol that can be sucked up and improving the sucking experience. It should be noted that in some embodiments, the material of the restricting part 53 includes, but is not limited to, at least one of stainless steel, aluminum nitride, silicon carbide, alumina, zirconium oxide, and silicon nitride.

[0057] In other embodiments, the limiting part 53 has a porous and loose structure, and the porosity of the limiting part 53 is less than that of the guiding part 51.

[0058] Specifically, in some embodiments, the limiting part 53 has a porous and loose structure, that is, the limiting part 53 has multiple micropores. In this case, the limiting part 53 can also allow external gas to flow to the medium 30, but the porosity of the limiting part 53 is less than that of the guiding part 51. This allows most of the external gas to flow to the first part 31 through the air inlet channel 511 of the guiding part 51, ensuring that the aerosol generated by the heating of the first part 31 can be effectively carried out, increasing the amount of aerosol that can be sucked up and improving the sucking experience.

[0059] In some embodiments, the aerosol generating article 100 further includes a cooling element 70 disposed within the accommodating cavity and located on the side of the medium 30 opposite to the guide 50, the cooling element 70 being used to cool the aerosol.

[0060] Specifically, in some embodiments, when a user inhales the aerosol to generate article 100, the aerosol generated by the heating of medium 30 can be inhaled by the user after flowing through the cooling element 70, and during the process of the aerosol flowing through the cooling element 70, the cooling element 70 can cool the aerosol to ensure that the temperature of the aerosol is suitable and improve the user's inhalation experience.

[0061] Furthermore, please combine Figure 3 In some embodiments, the cooling component 70 includes a first loading portion 71, a second loading portion 73, and a plurality of support portions 75. The first loading portion 71 has a first channel 711 along the length direction X, and the first channel 711 is in corresponding communication with at least a portion of the first portion 31. The second loading portion 73 surrounds the first loading portion 71 and is connected to the body 10. The plurality of support portions 75 are spaced apart between the first loading portion 71 and the second loading portion 73. The first loading portion 71, the second loading portion 73, and the support portions 75 together form a second channel 701 along the length direction X. The second channel 701 is in corresponding communication with at least a portion of the second portion 33. Both the first channel 711 and the second channel 701 are used to allow aerosol to flow out of the aerosol-generated article 100.

[0062] Specifically, in some embodiments, when a user inhales the aerosol generating article 100 and the first part 31 of the medium 30 is heated, the first part 31 of the medium 30 carbonizes and couples with external gas (including at least external gas flowing into the aerosol generating article 100 through the air inlet channel 511) to form an aerosol, and the formed aerosol can be inhaled by the user through the second channel 701; when a user inhales the aerosol generating article 100 and the second part 33 of the medium 30 is heated, the second part 33 of the medium 30 carbonizes and couples with external gas to form an aerosol, and the formed aerosol can be inhaled by the user through the first channel 711. It is understood that the aerosol generated by the first part 31 can also be inhaled by the user through the first channel 711, and the aerosol generated by the second part 33 can also be inhaled by the user through the second channel 701.

[0063] It should be noted that, in some embodiments, the cross-sectional shape of the first loading part 71 and the second loading part 73 may both be annular, the first channel 711 includes the inner cavity of the first loading part 71, and the second channel 701 includes the gap between two adjacent support parts 75.

[0064] In some embodiments, the first loading part 71, the second loading part 73, and the support part 75 together form a third channel 703 perpendicular to the length direction X. One end of the third channel 703 is connected to the first channel 711, and the other end is connected to the outside gas. The third channel 703 is used to allow the outside gas to flow into the first channel 711.

[0065] Specifically, in some embodiments, the support portion 75 is provided with a through groove 751, the first loading portion 71 is provided with a first perforation 713, and the second loading portion 73 is provided with a second perforation 731. Both the first perforation 713 and the second perforation 731 are connected to the through groove 751 and together form a third channel 703. When the user aspirates the aerosol to generate the product 100, external gas can flow into the first channel 711 sequentially through the second perforation 731, the through groove 751, and the first perforation 713.

[0066] In some embodiments, the aerosol generating article 100 further includes a filter element 90. The filter element 90 is disposed within the accommodating cavity and located on the side of the cooling element 70 opposite to the medium 30, and the filter element 90 is used to filter the aerosol.

[0067] Specifically, in some embodiments, a user can inhale the aerosol-generating product 100 through the filter element 90 to draw the generated aerosol into their mouth. The filter element 90 can filter out some impurities (including stray gases) in the aerosol, preventing the user from inhaling impurities and improving the user's inhalation experience. For example, the filter element 90 may include a porous material, such as filter cotton or porous ceramics, etc., which is not limited in this application. The porous material facilitates the flow of gas and aerosol and has good adsorption capacity, effectively adsorbing impurities in the airflow and preventing the user from inhaling impurities.

[0068] Please see Figure 2 , Figure 4 , Figure 5 or Figure 6 In some embodiments, the body 10 includes a first end face 101 and a second end face 103 facing away from each other, and the guide 50 is closer to the first end face 101 than the second end face 103.

[0069] Specifically, in some embodiments, the guide 50, medium 30, cooling element 70 and filter 90 are sequentially arranged in the direction from the first end face 101 to the second end face 103. Thus, when the aerosol generating product 100 is drawn in, the outside gas can flow through the guide 50 to the medium 30, so that the medium 30 generates aerosol when heated, and the generated aerosol can be drawn in by the user by passing through the cooling element 70 and the filter 90 in sequence.

[0070] The following describes four specific embodiments of the aerosol generating article 100 of this application with reference to the accompanying drawings.

[0071] Example 1 of this application

[0072] Please see Figure 2 In Embodiment 1, at least a portion of the guide portion 51 is disposed around the outer peripheral wall 5301 of the restricting portion 53. This ensures that, in the longitudinal direction X of the aerosol generating article 100, at least a portion of the guide portion 51 is opposite to the first portion 31, and the restricting portion 53 is opposite to the second portion 33, allowing most of the external gas to flow to the first portion 31, ensuring that the aerosol generated in the first portion 31 can be effectively carried out, increasing the amount of aerosol that can be drawn out, and improving the inhalation experience.

[0073] In some embodiments, the limiting portion 53 includes opposing first and second ends, and a peripheral wall connecting the first and second ends, along the length X of the aerosol generating article 100. In some examples, the size of the limiting portion 53 is the same as the size of the guiding portion 51 along the length X of the aerosol generating article 100. In this case, the first and second ends of the limiting portion 53 are flush with the end faces of the guiding portion 51 along the length X of the aerosol generating article 100. In other examples, the size of the limiting portion 53 is smaller than the size of the guiding portion 51 along the length X of the aerosol generating article 100. In this case, the first and / or second ends of the limiting portion 53 are located within the guiding portion 51; or, one of the first and second ends of the limiting portion 53 is located within the guiding portion 51, and the other end face of the limiting portion 53 is flush with the end face of the aerosol generating article 100 along the length X of the aerosol generating article 100.

[0074] In this embodiment, we will only describe an example in which the size of the limiting part 53 and the size of the guiding part 51 are the same in the length direction X of the aerosol generating article 100.

[0075] In this embodiment, the outer peripheral wall 5301 of the limiting part 53 is perpendicular to the first end face 101. Specifically, the shape of the limiting part 53 includes, but is not limited to, a cylinder, a cuboid, a cube, and other polygonal prisms. For example, the shape of the limiting part 53 includes a cylinder, and the cross-sectional shape of the limiting part 53 is circular. In this case, the cross-sectional shape of the guiding part 51 can be annular.

[0076] In this embodiment, the ratio of the cross-sectional area of ​​the limiting part 53 to the cross-sectional area of ​​the medium 30 is 0.2-0.8. Specifically, in some embodiments, the ratio of the cross-sectional area of ​​the limiting part 53 to the cross-sectional area of ​​the medium 30 can be any one of 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, and 0.8, or any value between any two of these values.

[0077] If the ratio of the cross-sectional area of ​​the restricting part 53 to the cross-sectional area of ​​the medium 30 is less than 0.2, most of the external gas cannot flow to the first part 31, resulting in the aerosol generated in the first part 31 not being effectively carried out, affecting the suction experience. If the ratio of the cross-sectional area of ​​the restricting part 53 to the cross-sectional area of ​​the medium 30 is greater than 0.8, it will result in insufficient air intake, and the aerosol generating product 100 will experience greater resistance during suction, leading to poor suction or even the inability to suction the aerosol. In this embodiment, the ratio of the cross-sectional area of ​​the restricting part 53 to the cross-sectional area of ​​the medium 30 is 0.2-0.8. This allows most of the external gas to flow to the first part 31, ensuring that the aerosol generated in the first part 31 is effectively carried out, increasing the amount of suctionable aerosol and improving the suction experience. Furthermore, it ensures that the suction resistance meets the requirements, guaranteeing normal suction for the user. It should be noted that the suction resistance refers to the resistance of the aerosol generating product 100 during suction.

[0078] Furthermore, in this embodiment, the ratio of the cross-sectional area of ​​the limiting part 53 to the cross-sectional area of ​​the medium 30 is 0.4. This allows most of the external gas to flow to the first part 31, ensuring that the aerosol generated in the first part 31 is effectively carried out, increasing the amount of aerosol that can be drawn out and improving the suction experience. On the other hand, it ensures that the suction resistance meets the requirements during suction, guaranteeing normal suction for the user. It should be noted that the suction resistance can be the resistance of the aerosol generating product 100 when it is drawn out.

[0079] Using the technical solution in this embodiment, most of the external gas can flow to the first part 31. When the aerosol generating device 300 heats the aerosol generating product 100 by means of circumferential heating, the air inlet channel 511 can be precisely matched with the initial carbonization area of ​​the medium 30 (i.e., the first part 31), thereby ensuring that the generated aerosol is effectively carried out, increasing the amount of aerosol that can be sucked up, and improving the sucking taste.

[0080] Example 2 of this application

[0081] Please see Figure 4 In Embodiment 2, at least a portion of the guide portion 51 is disposed around the outer peripheral wall 5301 of the restricting portion 53. This ensures that, in the longitudinal direction X of the aerosol generating article 100, at least a portion of the guide portion 51 is opposite to the first portion 31, and the restricting portion 53 is opposite to the second portion 33, allowing most of the external gas to flow to the first portion 31, ensuring that the aerosol generated in the first portion 31 can be effectively carried out, increasing the amount of aerosol that can be drawn out, and improving the inhalation experience.

[0082] In some embodiments, the limiting portion 53 includes opposing first and second ends, and a peripheral wall connecting the first and second ends, along the length X of the aerosol generating article 100. In some examples, the size of the limiting portion 53 is the same as the size of the guiding portion 51 along the length X of the aerosol generating article 100. In this case, the first and second ends of the limiting portion 53 are flush with the end faces of the guiding portion 51 along the length X of the aerosol generating article 100. In other examples, the size of the limiting portion 53 is smaller than the size of the guiding portion 51 along the length X of the aerosol generating article 100. In this case, the first and / or second ends of the limiting portion 53 are located within the guiding portion 51; or, one of the first and second ends of the limiting portion 53 is located within the guiding portion 51, and the other end face of the limiting portion 53 is flush with the end face of the aerosol generating article 100 along the length X of the aerosol generating article 100.

[0083] In this embodiment, we will only describe an example in which the size of the limiting part 53 and the size of the guiding part 51 are the same in the length direction X of the aerosol generating article 100.

[0084] In this embodiment, the outer peripheral wall 5301 of the limiting portion 53 is inclined relative to the first end face 101, and the slope of the outer peripheral wall 5301 of the limiting portion 53 remains unchanged. That is, the included angle formed between the outer peripheral wall 5301 of the limiting portion 53 and the first end face 101 remains unchanged. For example, the shape of the limiting portion 53 may be approximately frustum-shaped.

[0085] Specifically, in this embodiment, the cross-sectional size of the limiting part 53 gradually increases and the cross-sectional size of the guiding part 51 gradually decreases in the direction from the first end face 101 to the second end face 103. As a result, the outer peripheral wall 5301 of the limiting part 53 can play a guiding role during the flow of external gas, thereby increasing the flow velocity of external gas in the guiding part 51, increasing the amount of air intake per unit time, and thus increasing the amount of aerosol generated, improving the user's inhalation experience.

[0086] Using the technical solution in this embodiment, most of the external gas can flow to the first part 31. When the aerosol generating device 300 heats the aerosol generating product 100 by means of circumferential heating, the air inlet channel 511 can be precisely matched with the initial carbonization area of ​​the medium 30 (i.e., the first part 31), thereby ensuring that the generated aerosol is effectively carried out, increasing the amount of aerosol that can be sucked up, and improving the sucking taste.

[0087] In addition, the outer peripheral wall 5301 of the limiting part 53 is inclined relative to the first end face 101, and the slope of the outer peripheral wall 5301 of the limiting part 53 remains unchanged. This can increase the flow rate of the external gas in the guiding part 51, increase the air intake per unit time, thereby increasing the amount of aerosol generated and improving the user's inhalation experience.

[0089] Please see Figure 5 In Embodiment 3, at least a portion of the guide portion 51 is disposed around the outer peripheral wall 5301 of the restricting portion 53. This ensures that, in the longitudinal direction X of the aerosol generating article 100, at least a portion of the guide portion 51 is opposite to the first portion 31, and the restricting portion 53 is opposite to the second portion 33, allowing most of the external gas to flow to the first portion 31, ensuring that the aerosol generated in the first portion 31 can be effectively carried out, increasing the amount of aerosol that can be drawn out, and improving the inhalation experience.

[0090] In some embodiments, the limiting portion 53 includes opposing first and second ends, and a peripheral wall connecting the first and second ends, along the length X of the aerosol generating article 100. In some examples, the size of the limiting portion 53 is the same as the size of the guiding portion 51 along the length X of the aerosol generating article 100. In this case, the first and second ends of the limiting portion 53 are flush with the end faces of the guiding portion 51 along the length X of the aerosol generating article 100. In other examples, the size of the limiting portion 53 is smaller than the size of the guiding portion 51 along the length X of the aerosol generating article 100. In this case, the first and / or second ends of the limiting portion 53 are located within the guiding portion 51; or, one of the first and second ends of the limiting portion 53 is located within the guiding portion 51, and the other end face of the limiting portion 53 is flush with the end face of the aerosol generating article 100 along the length X of the aerosol generating article 100.

[0091] In this embodiment, we will only describe an example in which the size of the limiting part 53 and the size of the guiding part 51 are the same in the length direction X of the aerosol generating article 100.

[0092] In this embodiment, the outer peripheral wall 5301 of the limiting part 53 is inclined relative to the first end face 101, and the slope of the outer peripheral wall 5301 of the limiting part 53 gradually decreases. That is, in the direction from the first end face 101 to the second end face 103, the included angle formed between the outer peripheral wall 5301 of the limiting part 53 and the first end face 101 gradually decreases.

[0093] Specifically, in this embodiment, the cross-sectional size of the limiting part 53 gradually increases and the cross-sectional size of the guiding part 51 gradually decreases in the direction from the first end face 101 to the second end face 103. As a result, the outer peripheral wall 5301 of the limiting part 53 can play a guiding role during the flow of external gas, thereby increasing the flow velocity of external gas in the guiding part 51, increasing the amount of air intake per unit time, and thus increasing the amount of aerosol generated, improving the user's inhalation experience.

[0094] Using the technical solution in this embodiment, most of the external gas can flow to the first part 31. When the aerosol generating device 300 heats the aerosol generating product 100 by means of circumferential heating, the air inlet channel 511 can be precisely matched with the initial carbonization area of ​​the medium 30 (i.e., the first part 31), thereby ensuring that the generated aerosol is effectively carried out, increasing the amount of aerosol that can be sucked up, and improving the sucking taste.

[0095] In addition, the outer peripheral wall 5301 of the limiting part 53 is inclined relative to the first end face 101, and the slope of the outer peripheral wall 5301 of the limiting part 53 gradually decreases, thereby increasing the flow rate of external gas in the guiding part 51, increasing the air intake per unit time, thereby increasing the amount of aerosol generated and improving the user's inhalation experience.

[0096] Example 4 of this application

[0097] Please see Figure 6 In Embodiment 4, at least a portion of the guide portion 51 is disposed around the outer peripheral wall 5301 of the restricting portion 53. This ensures that, in the longitudinal direction X of the aerosol generating article 100, at least a portion of the guide portion 51 is opposite to the first portion 31, and the restricting portion 53 is opposite to the second portion 33, allowing most of the external gas to flow to the first portion 31, ensuring that the aerosol generated in the first portion 31 can be effectively carried out, increasing the amount of aerosol that can be drawn out, and improving the inhalation experience.

[0098] In some embodiments, the limiting portion 53 includes opposing first and second ends, and a peripheral wall connecting the first and second ends, along the length X of the aerosol generating article 100. In some examples, the size of the limiting portion 53 is the same as the size of the guiding portion 51 along the length X of the aerosol generating article 100. In this case, the first and second ends of the limiting portion 53 are flush with the end faces of the guiding portion 51 along the length X of the aerosol generating article 100. In other examples, the size of the limiting portion 53 is smaller than the size of the guiding portion 51 along the length X of the aerosol generating article 100. In this case, the first and / or second ends of the limiting portion 53 are located within the guiding portion 51; or, one of the first and second ends of the limiting portion 53 is located within the guiding portion 51, and the other end face of the limiting portion 53 is flush with the end face of the aerosol generating article 100 along the length X of the aerosol generating article 100.

[0099] In this embodiment, the limiting part 53 includes a cylindrical first sub-part 531 and a second sub-part 533. The first sub-part 531 includes a first end and a second end opposite to each other, with the first end of the first sub-part 531 being closer to the first end face 101 than the second end of the first sub-part 531. The second sub-part 533 is connected to the second end of the first sub-part 531. The first sub-part 531 has a cylindrical structure, meaning it has a hollow cavity. Compared to a solid structure, the first sub-part 531 is lighter, which helps to achieve a lighter weight for the aerosol-generating article 100.

[0100] Specifically, in some embodiments, the first end of the first sub-part 531 (i.e., the first end of the limiting part 53) and the end of the second sub-part 533 opposite to the first sub-part 531 (i.e., the second end of the limiting part 53) can be flush with the two end faces of the guide part 51 in the longitudinal direction X of the aerosol generating article 100, respectively. In this case, the size of the limiting part 53 and the size of the guide part 51 are the same in the longitudinal direction X of the aerosol generating article 100. In other embodiments, the first end of the first sub-part 531 is flush with the end face of the guide part 51 in the longitudinal direction X of the aerosol generating article 100, and the second sub-part 533 is completely embedded in the guide part 51. In this case, the size of the limiting part 53 is smaller than the size of the guide part 51 in the longitudinal direction X of the aerosol generating article 100.

[0101] In this embodiment, the first end of the first sub-part 531 is flush with the end face of the guide part 51 in the length direction X of the aerosol generating article 100, and the second sub-part 533 is completely embedded in the guide part 51.

[0102] It should be noted that, in this embodiment, the outer peripheral wall 5301 of the limiting part 53 (including the outer peripheral wall 5301 of the first sub-part 531) can be perpendicular to the first end face 101.

[0103] Using the technical solution in this embodiment, most of the external gas can flow to the first part 31. When the aerosol generating device 300 heats the aerosol generating product 100 by means of circumferential heating, the air inlet channel 511 can be precisely matched with the initial carbonization area of ​​the medium 30 (i.e., the first part 31), thereby ensuring that the generated aerosol is effectively carried out, increasing the amount of aerosol that can be sucked up, and improving the sucking taste.

[0104] In addition, the limiting part 53 includes a cylindrical first sub-part 531, that is, the first sub-part 531 has a hollow cavity. Compared with the first sub-part 531 being a solid structure, the first sub-part 531 is lighter in weight, which can help to achieve the weight reduction of the aerosol generation article 100.
