Referring to fig. 1 to 4, the present invention provides an air heating body of an aerosol generator, which includes a hollow heating tube 100, wherein at least one heating net 2 is arranged at one end of the heating tube 100 along an axial direction to form an air heating cavity 12. The opposite end of the heating tube 100 is provided with a placement slot 11 for placement of smokable material 200, said placement slot 11 being in communication with said air heating chamber 12. In the embodiment, the heating nets 2 are sequentially arranged in the heating pipe 100 to form the air heating cavity 12, so that the contact area between air and the heating body is increased, and the air heating efficiency is improved.

In this embodiment, as shown in fig. 2, the heating pipe 100 includes a heat conducting pipe 1 and a heat generating layer (not shown) disposed on an outer periphery of the heat conducting pipe 1. The heat generated by the heat generating layer is transferred through the heat pipe 1 to the smokable material 200 contained within the heat pipe 1, thereby creating circumferential heating. The heating layer can adopt one or a combination of a plurality of winding resistance wire layers, printing thick film resistance layers, infrared heating material coatings or graphene heating material layers. The heat conductive pipe 1 is made of a material having heat conductive and electric conductive properties, such as a metal pipe. The heat conductive pipes 1 may be circular, square, oval, or the like. The smokable material 200 may be in the form of particles, naturally arranged filaments, or an ordered arrangement of filaments to form a cylindrical structure. In the embodiment, the heat pipe 1 is used for circumferentially heating the smokable material 200, and the air heating cavity 12 is arranged at the bottom of the smokable material 200 to heat the smokable material, so that a heating mode combining circumferential heating and bottom air heating is formed, and the heating efficiency is improved. In practical application, the air heating may be performed as an auxiliary or supplementary heating manner of the circumferential heating, or may be performed simultaneously with the circumferential heating. For example, it may be activated before circumferential heating commences to preheat the smokable material 200 to raise the temperature of the smokable material 200 as quickly as possible, increasing the efficiency of aerosol generation.

Preferably, as shown in fig. 1 and 2, the smokable material 200 is contained in the heat conductive pipe 1 with a gap from the inner wall of the heat conductive pipe 1, which is beneficial for heat dissipation. In practical applications, since the smokable material 200 is mostly arranged in a cylindrical structure, the heat conductive pipes 1 can be arranged as square heat conductive pipes 1. The length of square heat pipe 1 cross section equals the diameter of smokable material 200, has not only reserved the clearance like this but also has carried on spacingly through the side of heat pipe 1 to smokable material 200, prevents that it from producing in the suction process and rocking. It should be noted that, it is also possible to adopt a heat transfer pipe 1 having another shape, and to provide a holder in the heat transfer pipe 1, fix the smokable material 200 by the holder, and form a gap between the smokable material 200 and the heat transfer pipe 1.

In the present embodiment, as shown in fig. 3 and 4, the heat generating net 2 has a shape and a size adapted to the heat conductive pipes 1. The edge of the heating net 2 is welded on the inner wall of the heat conduction pipe 1. For example, the heat pipe 1 is a square heat pipe 1, and then the heating net 2 is also a square fitting. Each side of the heating net 2 is welded to the corresponding side wall of the heat conducting pipe 1. Not only can each heating net 2 be fixed by welding, but also the heating net 2 and the heat conduction pipe 1 can be electrically connected. When the heat conduction pipe 1 is conducted with the power supply, the power supply can be provided for the heating network 2. Preferably, the plane where the heating net 2 is located is perpendicular to the axial direction of the heat conduction pipe 1, so that the contact area between the side edge of the heating net 2 and the side wall of the heat conduction pipe 1 can be increased, meanwhile, the center of gravity of the heating net 2 is coincided with the center of the side edge of the heat conduction pipe 1, the stress balance of the heating net 2 is facilitated, and the installation stability is improved.

Further, the heat generation nets 2 are sequentially arranged along the axial direction of the heat conduction pipes 1. The intervals between the adjacent heat generation nets 2 may be equal or unequal. Preferably, at least one of said heat generating networks 2 is equally spaced, which facilitates the formation of stable air flow channels 3. The number of the heat generating nets 2 may be 1, 2 or more. The number and the interval of the heating nets 2 can be set according to actual requirements. The heat generation net 2 has a plurality of meshes 21, and the number of meshes 21 in each heat generation net 2 may be the same or different. The meshes 21 on each heat generation net 2 may be the same shape, for example, all of the meshes 21 are circular meshes 21; for example, the meshes 21 on one heating net 2 may be circular, and the meshes 21 on the other heating net 2 may be square. The mesh 21 distribution on each heat generation network 2 may be the same or different. Preferably, the meshes 21 of at least one heating net 2 are uniformly distributed. For example. The meshes 21 of the heat generating net 2 are arranged at equal intervals in sequence with the center of the heat generating net 2 as a symmetrical center. Thus, the uniform separation and sieving of the meshes 21 to the air are facilitated, the uniformity of air heating is improved, and the probability of nonuniform heating is effectively reduced.

Preferably, as shown in fig. 3, the meshes 21 of the heat generation nets 2 correspond one to one. That is, the mesh 21 distribution on each heat generation net 2 is completely the same, and the position of each mesh 21 is completely the same as the position of the corresponding mesh 21, and the airflow passage 3 parallel to the axial direction of the heat transfer pipe 1 is formed. Therefore, the meshes 21 are ensured to be sequentially opposite to corresponding meshes 21 on other heating nets 2, so that relatively continuous airflow channels 3 are formed, airflow sequentially and smoothly passes through the corresponding meshes 21, namely, the airflow smoothly flows out of the airflow channels 3, the air circulation efficiency is improved, and heat loss is reduced. In practical application, the meshes 21 on the same heating net 2 may be the same or different in size; the mesh 21 of the different heat generating nets 2 may be the same or different. Preferably, the mesh openings 21 of the heating nets 2 are all the same size, which is favorable for forming uniform and stable airflow channels 3. It should be noted that the size of the mesh 21 may be set according to actual requirements, such as resistance values and heat generation efficiency of the respective portions of the heat generation net 2. For example, the mesh 21 of the heating net 2 near the center is larger, and the mesh 21 far from the center is smaller; the mesh 21 of each heat generation network 2 may be provided so as to sequentially increase or decrease in the axial direction of the heat transfer pipe 1, or so as to increase and decrease in the axial direction.

Further, the arrangement shape of the meshes 21 on the heat generation net 2 is adapted to the shape of the heat transfer pipe 1. For example, in the present embodiment, the cross section of the heat transfer pipe 1 is square, and correspondingly, the heat generating net 2 is also a square net, a plurality of meshes 21 on the heat generating net 2 are sequentially arranged in parallel to form a strip-shaped structure parallel to the side of the heat generating net 2, and finally the strip-shaped structure is formed into a square shape identical to the shape of the heat generating net 2. This makes the airflow channels 3 formed in the subsequent meshes 21 parallel to the side walls of the heat transfer pipe 1, which is advantageous for reducing the resistance to air circulation, and increases the layout area of the meshes 21, thereby increasing the number of the airflow channels 3 and further improving the efficiency of air heating.

In this embodiment, as shown in fig. 2 to 4, the bottom wall 111 of the placing slot 11 is provided with at least one air outlet 112 communicated with the air heating cavity 12, one end of the heating tube 100 away from the placing slot 11 is provided with a bottom plate 13, and the bottom plate 13 is provided with at least one air inlet 131 communicated with the air heating cavity 12. Preferably, the number of the air outlets 112 is one, and the area of one air outlet 112 is slightly smaller than the cross-sectional area of the heat conductive pipe 1. The circular shape of the air outlet 112 coincides with the center of the bottom wall 111, and the bottom wall 111 forms an annular structure enclosing the air outlet 112. When the smokable material 200 is received in the placement slot 11, the bottom end of the smokable material 200 rests on the ring structure to provide support and spacing. In practical applications, the shape of the air outlet 112 may be circular, square or other irregular shapes. Preferably, the shape of the air outlet 112 is the same as that of the bottom wall 111, so that the bottom wall 111 forms a ring structure with the same size on each side, which is beneficial for forming a stable and uniform support structure. Of course, the shape of the air outlet 112 may also be the same as the shape of the smokable material 200, and the size of the air outlet 112 is smaller than the size of the smokable material 200 to prevent the smokable material 200 from falling into the air heating chamber 12.

In this embodiment, the number of the air inlets 131 may be one, two or more. The air inlet 131 may be located at any position of the bottom plate 13, such as the center of the bottom plate 13. Preferably, the number of the air inlets 131 is the same as the number of the meshes 21 on the heating net 2, and the air inlets correspond to the meshes one by one. That is, each of the air inlets 131 corresponds to one of the meshes 21, and communicates with a plurality of corresponding meshes 21 to form an air flow path 3, and each of the air inlets 131 serves as an air inlet end of the air flow path 3 formed thereby. Through setting up air inlet 131 and mesh 21 one-to-one for in each airflow channel 3 is flowed into promptly to the outside air when getting into the heating body, not only improved the circulation efficiency of air, still further increased the area of contact of air with mesh 21, thereby improved heating efficiency. This embodiment is through setting up air heating chamber in air heating body bottom for the air that gets into from the air inlet is at first by the heating network heating of air heating intracavity after being the hot-air, in the standing groove is flowed into via air current channel and gas outlet respectively to the subdividing, realizes carrying out the mode that air heating and circumference heating combined together to the smokeable material and heats, has improved heating efficiency.
