And as used in this application, "connection" and "coupling", unless otherwise specified, both include direct and indirect connection (coupling).

[0028] Aiming at the problem of uneven heating of the smoking section caused by the central heating method of the existing aerosol-generating article. In this application, by horizontally arranging the heating element and fitting it to the matrix section, when heating is used, the entire contact surface of the matrix section can be directly heated, that is, it has contact with both the middle and the periphery of the matrix section, increasing the contact area between the heating element and the matrix section, making the heating of the matrix section more uniform. And a heat conductor is provided, which is arranged in a spiral or wavy shape, increasing the contact area with the matrix section, and can transfer heat to the matrix section better and more evenly through the heat conductor. At the same time, it can make the combination of the heat conductor and the matrix section closer, which can further improve the smoking effect.

[0029] In one embodiment, as Figures 1-5 shown, an aerosol-generating article is provided, including a matrix section 11, a heating element 12, etc. When the aerosol-generating article is heated, the smoking substance in the matrix section 11 is heated to generate aerosol for the user to inhale.

[0030] The heating element 12 can heat the matrix section 11 to generate aerosol. The heating element 12 includes a heating body 121 and a heat conductor 122. The heating body 121 can be horizontally arranged; the heat conductor 122 is connected to the heating body 121 and extends longitudinally in the matrix section 11. Herein, the horizontal direction in this embodiment is the direction substantially parallel to the end face of the matrix section 11, and the longitudinal direction is the direction substantially perpendicular to the end face of the matrix section 11.

[0031] The heating body 121 is in contact with the matrix section 11, and the heat emitted by the heating body 121 can directly heat the matrix section 11 through the contact surface. When using the aerosol-generating article for heating, the entire contact surface of the matrix section 11 can be directly heated, that is, both the middle and the periphery of the matrix section 11 can be heated, and the matrix section 11 is heated more evenly, having the advantage of good heating effect.

[0032] The heat conductor 122 is spiral or wavy, increasing the surface area in contact with the substrate section 11, thereby enabling a tighter bond between the heat conductor 122 and the substrate section 11. Moreover, the increased surface area in contact also increases the area of heat conduction, allowing the heat of the heating body 121 to be better transferred to the substrate section 11 through the heat conductor 122, further enhancing the smoking effect.

[0033] In one embodiment, the aerosol-generating article further includes a cylindrical housing 13. The hollow housing 13 has a first end 131 and a second end 132. The first end 131 can be a proximal end, i.e., the first end 131 is the end that the user sucks when inhaling; the second end 132 can be a distal end, i.e., the second end 132 is the end away from the user's inhalation.

[0034] The substrate section 11 is disposed within the housing 13. The heating body 121 includes a first heating element 1211, and the first heating element 1211 is attached to the end face of the substrate section 11 near the second end 132. By heating the end face of the substrate section 11 with the first heating element 1211, an aerosol is generated for the user to inhale. While the first heating element 1211 heats the substrate section 11, it can also intercept, to a certain extent, the substances in the substrate section 11 from leaking out of the aerosol-generating article, reducing the residues left on the heating device after use.

[0035] In one embodiment, as Figure 1 shown, the first heating element 1211 is provided with a first air inlet hole 1213 that penetrates axially through the aerosol-generating article. During use, the substrate section 11 is heated by the first heating element 1211, and the smoking substances in the substrate section 11 are heated to generate an aerosol; during inhalation, outside air enters the substrate section 11 through the first air inlet hole 1213 and carries out the aerosol for the user to inhale.

[0036] In some embodiments, as Figure 2 shown, the first heating element 1211 has an airtight structure and its cross-sectional shape is substantially the same as the cross-sectional shape of the housing 13. For example, the first heating element 1211 in a cylindrical aerosol-generating article can be a disc or a cylindrical solid, etc. The edge of the first heating element 1211 is sealingly fitted with the inner wall of the housing 13 so that the first heating element 1211 seals the end face of the substrate section 11, and the aerosol generated by the substrate section 11 flows towards the first end 131.

[0037] Further, a second air inlet hole 133 is provided through the side wall of the housing 13. The second air inlet hole 133 is provided on a section of the side wall of the housing 13 between the first heating element 12 and the first end 131. By introducing outside air through the second air inlet hole 133, the aerosol generated by the substrate section 11 is carried out.

[0038] In some embodiments, the second air inlet hole 133 may penetrate through the housing 13 on the outer periphery of the matrix section 11. Further, the second air inlet hole 133 may be located on the housing 13 at the lower outer periphery of the matrix section 11. In some embodiments, the distance between the second air inlet hole 133 and the end face of the matrix section 11 close to the second end 132 is 1-20 mm. In some embodiments, the second air inlet hole 133 includes one or more, and the shape of the second air inlet hole 133 may be one or more of a round hole, a square hole, a round hole, a polygonal opening, and an opening with an irregular shape. The opening size is 0.05-3 mm, and the opening size is the maximum width of the contour of the opening, such as the diameter of a round hole, the major diameter of an ellipse, etc.

[0039] In some embodiments, the second air inlet holes 133 may be multiple and evenly distributed around the matrix section 11, so as to make the air intake more uniform.

[0040] In one embodiment, the part of the matrix section 11 close to the first heating element 12 is in communication with the outside through the second air inlet hole 133. During suction, the outside air flow can directly enter the matrix section 11 to quickly carry out the aerosol generated by the matrix section 11. It can be understood that the opening position of the second air inlet hole 133 can be adjusted according to actual needs.

[0041] In one embodiment, as Figure 3 shown, the heating body 121 further includes at least one second heating element 1212 spaced apart from the first heating element 1211, and the second heating element 1212 is horizontally arranged in the matrix section 11. When there are multiple second heating elements 1212, the second heating elements 1212 are spaced apart along the axial direction of the housing 13. By providing one or more second heating elements 1212, the heat of the first heating element 1211 and the second heating element 1212 are spaced apart, and each layer provides energy to the matrix section respectively, so as to quickly and evenly transfer the heat to the matrix section 11.

[0042] In one embodiment, the heat conductor 122 passes through and is connected to the second heating element 1212.

[0043] In one embodiment, the second heating element 1212 is provided with an axially penetrating through hole 1214; and / or, there is a ventilation gap 1215 between the second heating element 1212 and the inner wall of the housing 13. When the user sucks, the air flow entering from the air inlet hole can flow through the ventilation gap 1215 or the through hole 1214 to carry out the aerosol generated by the matrix section 11 and reach the first end 131 for the user to inhale.

[0044] In some embodiments, the heat conductor 122 passes through the second heating element 1212 and is connected to the second heating element 1212.

[0045] In some embodiments, the first heating element 1211 and the second heating element 1212 can be integrally formed with the heat conductor 122, thereby simplifying the assembly and reducing the production cost.

[0046] In some embodiments, the first heating element 1211 and the second heating element 1212 are detachably connected to the heat conductor 122 to reduce the production difficulty.

[0047] In some embodiments, the heat conductor 122 is provided with a plurality of spaced-apart clamping positions along the length direction, and the first heating element 1211 and the second heating element 1212 are clamped onto the clamping positions.

[0048] In some embodiments, the heat conductor 122 is provided with a plurality of spaced-apart positioning steps along the length direction, and each of the first heating element 1211 and the second heating element 1212 is provided with a positioning hole that cooperates with the positioning step. Through the cooperation of the positioning step and the positioning hole, the first heating element 1211 and the second heating element 1212 are spaced apart and installed on the heat conductor 122.

[0049] In some embodiments, the matrix section 11 is made of a smoke-generating material, and the smoke-generating material includes one or more of smoke-generating particles, smoke-generating flakes, smoke-generating filaments, or a smoke-generating block having a microporous structure.

[0050] In some embodiments, a through hole 1214 is correspondingly formed in the second heating element 1212 and / or there is a ventilation gap 1215 between the second heating element 1212 and the side wall of the housing 13. During assembly, the heating element 12 can be integrally installed into the housing 13, so that the first heating element 1211 seals the cavity formed by the housing 13. Smoke-generating particles are selected and filled into the cavity from the first end to cover all the second heating elements 1212. The smoke-generating particles can fall through the ventilation gap 1215 and / or the through hole 1214, and the smoke-generating particles are compacted by means such as vibration, thereby forming the matrix section 11.

[0051] In some embodiments, during assembly, the first heating element 1211 can also be first sealed at the second end 132 of the housing 13, then the smoke-generating material is filled, then the second heating element 1212 is installed, and then the smoke-generating material is continuously filled on one side of the second heating element, and so on. The steps of filling the smoke-generating material and installing the second heating element are cycled as needed for multiple times.

[0052] In one embodiment, the heating body 121 is made of an induction heating material, which can sense the energy of the field and generate heat in a specific field. For example, the heating element 12 can be a magnetic induction heating material; and / or, the heat conductor 122 is a strip-shaped heat conductor made of a heat-conducting material; the heat conductor 122 includes one or more of graphite, graphene, boron nitride, alumina, and carbon materials, and can be formed by recombining one or more of graphite powder, graphene, boron nitride, alumina, and carbon powder, or can be other materials. In one embodiment, its thermal conductivity is 1-500 W / m.k.

[0053] In one embodiment, a spacer section 14 is provided on one side of the first heating element 1211 close to the second end 132. By providing the spacer section 14, after the aerosol generating article is heated and used, the heated end face will not be directly exposed, thus causing scalding to the user.

[0054] In some embodiments, the spacer section 14 includes a cavity portion 141, and the housing 13 forms a cavity portion 141 between the first heating element 1211 and the second end 132, and / or, the spacer section 14 includes a heat insulation member 142, and the heat insulation member 142 is connected to the housing 13 and blocks the second end 132 or is blocked on one side of the first heating element 1211 close to the second end 132; or, the spacer section 14 includes a heat insulation layer 143 provided on the outer surface of the first heating element 1211.

The cavity portion 141 is formed between the housing 13 at the first heating element 1211 and the second end 132 and is open to the second end 132. The provision of the cavity portion 141 positions the first heating element 1211 inside the housing 13, thus avoiding direct exposure and playing a role in preventing scalding of the user.

[0056] In some embodiments, as Figure 4 shown, the spacer section 14 includes a heat insulation member 142. The heat insulation member 142 is connected to the housing 13 and blocks the second end 132 or is blocked on one side of the first heating element 1211 close to the second end 132. By providing the heat insulation member 142, the risk of the user directly contacting the magnetic induction heating element can be further reduced, and the risk of being scalded can be further reduced.

[0057] It can be understood that a heat insulation member 142 can also be provided in the cavity portion 141, and a certain distance is left between the side of the heat insulation member 142 close to the second end 132 and the second end 132, further playing a role in preventing scalding.

The heat insulation layer 143 may be a heat insulation film or other heat insulation material attached to the outer wall surface of the first heating element 1211. Of course, the outer wall surface of the first heating element 1211 may be exposed on the lower end surface of the housing 13 or located inside the housing 13.

[0059] In one embodiment, the housing 13 is tubular, and the ratio of the height of the cavity section 141 in the axial direction to the diameter of the cavity section 141 is greater than or equal to 0.3:1.

[0060] In one embodiment, the aerosol-generating article further includes: a cooling section 16 and a filtering section 17 which are arranged in sequence from the second end 132 to the first end 131 inside the housing 13 and on the inner side of the matrix section 11.
