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

[0025] Regarding the problem of uneven heating of the matrix section caused by the central heating method of existing aerosol-generating products. 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, thus solving the problem of poor smoke generation effect due to insufficient temperature at the periphery of the matrix section in the central heating method; and, by setting a heat insulation layer between the periphery of the heating element and the inner wall of the housing, it is possible to avoid the housing from being heated and generating peculiar smells, further improving the user experience.

[0026] In one embodiment, as Figures 1 - 4 shown, there is provided an aerosol-generating article, including a cylindrical housing 11, a matrix section 12, a heating element 13, etc.

[0027] The matrix section 12 is arranged inside the housing 11. When the aerosol-generating article is heated, the smoke-generating substance in the matrix section 12 is heated to generate aerosol for the user to inhale.

[0028] The heating element 13 can heat the matrix section 12 to generate aerosol. The heating element 13 includes a heating element 131.

[0029] In some embodiments, the heating element 131 is an inductive heating element, which can sense the energy of the field and generate heat in a specific field. For example, the heating element 131 can be a magnetically inductive heating material, which can generate heat in a magnetic field to heat the matrix section 12. The heating element 131 can be horizontally arranged and fit with the matrix section 12, so as to perform surface heating on the matrix section 12. The periphery of the heating element 131 is close to the inner wall of the housing 11. For example, the heating element 131 can be in the shape of a sheet, a net, etc. The outer contour of the cross-section of the heating element 131 matches the outer contour of the cross-section of the matrix section 12. For example, they can both be circular; in one embodiment, the housing 11 is a cylindrical hollow housing, the matrix section 12 is filled in a section of the housing, the heating element 131 is or has an outer contour in the shape of a circular net structure, a disc, a cylinder, etc., and the area of the outer contour of the cross-section of the heating element 131 is close to the area of the cross-section of the matrix section 12. Herein, the horizontal direction in this embodiment is the direction parallel to the end face of the matrix section 12, and the vertical direction is the direction perpendicular to the end face of the matrix section 12, and the vertical direction is also the axial direction of the housing 11. In this way, the heating element 131 has a large contact with the smoke-generating substance in the matrix section, and both the middle and the periphery of the smoke-generating substance can be heated, and the smoke generation effect is good.

[0030] Further, the aerosol generating article further includes a heat insulation layer 14 disposed between the periphery of the heating element 131 and the inner wall of the housing 11. The heat insulation layer 14 spaces apart the heating element 131 and the inner wall of the housing 11, which can reduce the heat transfer of the heating element 131 to the housing 11, avoid the generation of strange smells due to heat of the housing 11, and affect the taste of the aerosol, thus ensuring the purity of the aerosol.

[0031] In some embodiments, the heat insulation layer 14 is at least disposed on the part where the heating element 131 and the inner wall of the housing 11 are close. Even the heating element 131 can be closely fitted with the housing 11 with the heat insulation layer 14 therebetween; the heat insulation layer can also be wrapped around the outer periphery of the entire matrix section 12, or can be disposed on the entire inner wall of the housing 11. There is no limitation here, as long as the heating element 131 and the housing 11 are spaced apart so that the housing 11 will not generate strange smells due to the heating of the heating element 131. The heat insulation layer 14 can be a heat-resistant and heat-insulating material such as aluminum foil.

[0032] During use, by placing the aerosol generating article in a heating device, the induction heating coil of the heating device generates a magnetic field to heat the heating element 131. The heat generated by the heating element 131 is transferred to the matrix section 12 to heat the matrix section 12 to generate an aerosol.

[0033] In one embodiment, the housing 11 has a first end 111 and a second end 112. The first end can be a proximal lip end, that is, the first end 111 is the end where the user sucks during suction; the second end 112 can be a distal lip end, that is, the second end 112 is the end away from the user's suction. The heating element 131 includes a first heating element 1311, and the first heating element 1311 is horizontally disposed on the end face of the matrix section 12 close to the second end 112. The end face of the matrix section 12 is heated by the first heating element 1311 to generate an aerosol for the user to suck. In one embodiment, the edge of the first heating element 1311 is hermetically fitted with the inner wall of the housing 11 through the heat insulation layer 14 to seal the matrix section 12 in the housing from the side close to the second end of the matrix section 12; in one embodiment, the first heating element 1311 can be solid, and at the same time, air inlet holes 113 are formed in the housing 11 on the outer periphery of the matrix section 12, so that residues such as e-liquid during the heating process of the matrix section 12 or the aerosol generating article are not easily leaked out from the second end 112 to contaminate the heating device.

[0034] In one embodiment, as Figure 2As shown, the heating element 131 further includes at least one second heating element 1312 of the first heating element. The second heating element 1312 is horizontally arranged in the matrix section 12. The first heating element 1311 and the second heating element 1312 are arranged at intervals along the axial direction of the housing 11. By providing one or more second heating elements 1312, the matrix section can be heated by the multi-layer second heating elements 1312 in each layer section, and then the heat can be quickly and evenly transferred to the matrix section 12.

[0035] In one embodiment, one side of the second heating element 1312 close to the first end 111 is communicated with the side close to the second end 112, that is, in a ventilation state, to ensure that the generated aerosol can pass through the second heating element 1312 and come out from the first end 111 for suction. In some embodiments, there is a ventilation gap 114 between the second heating element 1312 and the inner wall of the housing 11; and / or, the second heating element 1312 is provided with a pore channel connecting the side close to the first end 111 and the side close to the second end 112. The pore channel can be a through hole 1313 penetrating the second heating element 1312 along the axial direction of the housing, or other microporous structures.

[0036] In some embodiments, the first heating element 1311 and the second heating element 1312 can be made of the same or different materials.

[0037] In one embodiment, the heating element 13 further includes a heat conducting member 132. One end of the heat conducting member 132 is connected to the heating element 131, and the other end extends into the matrix section 12. Moreover, the heat conducting member 132 can extend into the matrix section 12 and be connected to the second heating element 1312. In addition to directly heating the matrix section 12, part of the heat generated by the first heating element 1311 can also be transferred to the heat conducting member 132 and introduced into the middle of the matrix section 12 by the heat conducting member 132, so as to increase the heat receiving area of the matrix section 12 and improve the smoke output speed.

[0038] In one embodiment, the heat conducting member 132 is a strip-shaped heat conducting member 132 made of a heat conducting material, such as a long strip-shaped sheet, a long strip-shaped column, a filament, etc., to transfer the heat of the heating element 131 to the matrix section.

[0039] In some embodiments, the heat conducting member 132 is made of one or several of graphite powder, graphene, boron nitride, alumina, carbon powder, and its thermal conductivity is 1-500 W / m·K. When the aerosol generating article is heated in an induction heating magnetic field, the temperature of the first heating element 1311 is higher than that of the heat conducting member 132, and the temperature difference range is 20-80 °C.

[0040] In one embodiment, the aerosol generating article further comprises: a cooling section 16 and a filtering section 17 which are located on the downstream side of the substrate section 12 within the housing 11 and are sequentially arranged from the second end 112 to the first end 111. In some embodiments, the aerosol generating article may further include a flavor carrier section 15. In some embodiments, the housing 11 may be a paper tube wrapped around the periphery of the substrate section 12, the flavor carrier section 15, the cooling section 16 and the filtering section 17, or a hollow cylinder made of other materials such as plastic, silica gel, etc. The flavor carrier section 15 is a structure containing flavoring components, and the flavoring components can be aspirated together with the aerosol.

[0041] In one embodiment, the substrate section 12 is made of a smoking material, and the smoking material includes one or more of the forms such as smoking particles, smoking flakes, smoking tobacco strands, and solid smoking blocks having a microporous structure.

[0042] In some embodiments, when the smoking material is in the form of smoking particles, through holes 1313 are correspondingly formed in the second heating element 1312 and / or there is a ventilation gap 114 between the second heating element 1312 and the side wall of the housing 11. During assembly, the first heating element 1311 can be first blocked at the second end 112 of the housing 11, and then the smoking particles are filled in; the smoking particles are compacted by means of vibration or the like, thereby forming a tight substrate section 12.

[0043] In some embodiments, when the smoking material is in the form of smoking flakes or smoking tobacco strands, the smoking material can be first filled in the space between the second heating elements 1312 and between the first heating element 1311 and the second heating elements 1312, so as to form an integral body and then be loaded into the housing 11.

[0044] In one embodiment, a spacer section 18 is provided on the side of the first heating element 1311 close to the second end 112. Through the arrangement of the spacer section 18, after the aerosol generating article is heated and used, the heated end face will not be directly exposed, thus causing scalding to the user.

[0045] In some embodiments, the spacer section 18 includes a cavity portion 181, and the housing 11 forms a cavity portion 181 between the first heating element 1311 and the second end 112, and / or the spacer section 18 includes a heat insulation member 182, and the heat insulation member 182 is connected to the housing 11 and blocks the second end 112 or is blocked on the side of the first heating element 1311 close to the second end 112; or the spacer section 18 includes a heat resistance member 183 provided on the outer surface of the first heating element 1311. The heat insulation member 182 and the heat resistance member 183 can be made of heat insulation materials, etc.

[0046] In one embodiment, as Figure 1As shown, the spacer section 18 includes a cavity portion 181 provided inside the housing 11; the cavity portion 181 is formed between the first heating element 1311 and the second end 112 of the housing 11 and is open to the second end 112. The setting of the cavity portion 181 positions the first heating element 1311 inside the housing 11, preventing the first heating element 1311 from being directly exposed, thus preventing the user from being scalded.

[0047] In some embodiments, as Figure 3 shown, the spacer section 18 includes a heat insulation member 182. The heat insulation member 182 is connected to the housing 11 and seals the second end 112 or is disposed on one side of the first heating element 1311 close to the second end 112. By providing the heat insulation member 182, the risk of the user directly contacting the magnetic induction heating member can be further reduced, and the risk of being scalded can be further reduced.

[0048] It can be understood that a heat insulation member 182 can also be provided in the cavity portion 181, with a certain distance left between the side of the heat insulation member 182 close to the second end 112 and the second end 112, further playing a role in preventing scalding.

[0049] In some embodiments, as Figure 4 shown, the spacer section 18 includes a heat resistance member 183 provided on the outer surface of the first heating element 1311. The heat resistance member 183 can be a heat insulation film or other heat insulation material attached to the outer wall surface of the first heating element 1311. Of course, the first heating element 1311 can be exposed on the lower end surface of the housing 11 or be located inside the housing 11.

[0050] In one embodiment, the housing 11 is a cylindrical hollow housing, and the ratio of the height of the cavity portion 181 in the axial direction to the diameter of the cavity portion 181 is greater than or equal to 0.3:1.

[0051] In one embodiment, as Figure 5 shown, the present application also provides an aerosol generating system, including an aerosol generating article 10 and a heating device 20. The aerosol generating article 10 is the aerosol generating article of any of the above embodiments. The heating device 20 includes an insertion space 21 for the aerosol generating article 10 to be inserted and a magnetic field generator 22 provided around the insertion space 21. The magnetic field generator 22 can be an induction heating coil matching the aerosol generating article 10. The first heating element 1311 of the aerosol generating article is heated by the induction heating coil, and the atomization matrix is heated through the heating body and the heat conducting member 132 of the aerosol generating article.

[0052] The above uses specific examples to elaborate on this application, which is only for helping to understand this application and is not intended to limit this application. For those skilled in the technical field to which this application pertains, based on the idea of this application, several simple deductions, deformations or substitutions can also be made.
