The heat generating body 13 may be an infrared radiation heat generating film and may be coated on the outer surface of the base 11. The infrared radiation heating film can be made of material with high infrared radiance, for example, Fe2O3、MnO2、Co2O3、ZrO2、SiO2、SiC、TiO2、Al2O3、CeO2、La2O3MgO, TiC, CrC, TiCN, cordierite and perovskite. The infrared radiation heating film can be connected with the positive electrode and the negative electrode of a power supply through two conductive elastic sheets 12, can generate heat after being electrified, and transmits the generated heat to the aerosol-forming substrate accommodated in the substrate 11 from the outer surface of the substrate 11 in an infrared radiation mode to heat the aerosol-forming substrate. The infrared radiation heating mode has stronger penetrating power and radiation power, and can realize the synchronous heating inside and outside the aerosol forming substrate, so that the heating is more uniform. In other embodiments, the heat generating body 13 may also be a resistance conduction heat generating film, or it may be a resistance conduction and infrared radiation composite heat generating film.
The base body 11 is tubular in shape with a receiving cavity 110 formed therein for receiving an aerosol-forming substrate. The substrate 11 may be made of a material that is resistant to high temperature and has a low thermal conductivity and a high infrared transmittance, such as ceramic, quartz glass, and the like. In the present embodiment, the base 11 is a quartz glass tube having a circular tube shape, and the receiving cavity 110 may axially penetrate through the base 11 and may be disposed coaxially with the base 11. In other embodiments, the base 11 may have other shapes such as an oval tube shape, a square tube shape, and the like.
The conductive elastic sheet 12 may be formed integrally by a metal material, such as low-impedance material, for example, phosphor copper or 316 stainless steel, and the surface thereof may be further provided with a metal plating layer, such as gold plating or silver plating.

The conducting part 1222 may be formed by extending one side edge of the connecting part 1221 away from the receiving part 121 and then pre-bending and deforming, so that the conducting part 1222 may generate elastic force to elastically contact the heating element 13, thereby achieving stable electrical connection with the heating element 13. The conduction part 1222 may have a substantially V-shape, and the V-shaped bottom thereof abuts against the heating element 13. Further, the V-shaped bottom of the conduction part 1222 can be designed to be a circular arc shape, so as to avoid the sharp-angled structure from scratching the heating element 13. In other embodiments, the connection portion 1221 may also be vertically connected to the socket portion 121, and it may also extend radially outward from an edge of one side of the socket portion 121 close to the heating element 13. In other embodiments, the connection portion 1221 may also form an angle with the socket portion 121.
The electrode portion 123 may be formed by one of the elastic arms 122 extending outward away from one side edge of the socket portion 121, and specifically, may be formed by one of the elastic arms 122 extending and then bending. The electrode portion 123 may be extended to a position away from the base 11 and the heating element 13 to facilitate wire bonding, and the bonding operation is facilitated.

In addition, because the welding spot is at a certain distance from the heating body 13, the welding spot can be prevented from melting due to overhigh temperature when the heating body 13 is heated, and the welding reliability is improved. In the present embodiment, the electrode portion 123 extends outward in the lateral direction and away from the base 11 and the heat generating body 13. In other embodiments, the electrode portion 123 may be processed into other structures.
In some embodiments, each conductive elastic piece 12 may further include a limiting portion 124 connected to the socket portion 121 and abutting against the end surface of the base 11. The limiting portion 124 may be a plurality of arc-shaped pieces, and the plurality of limiting portions 124 may be uniformly distributed at intervals along the circumferential direction of the sleeve portion 121. The limiting part 124 is arranged in a segmented mode, so that punch forming is facilitated. In addition, the plurality of limiting parts 124 can provide certain elastic deformation, and can well abut against the base body 11 to be in good contact with the base body 11 under the condition that the end face of the base body 11 is not flat. Specifically, in the present embodiment, there are four limiting portions 124. These four spacing portions 124 can stagger the setting with four elastic arms 122 along the circumference of cup joint portion 121, promptly, each spacing portion 124 is located between per two adjacent elastic arms 122's the circumferential position, and this structure can make things convenient for the setting of punching press tool, can once only with spacing portion 124 and elastic arm 122 stamping forming, still can further improve the good contact nature between electrically conductive shell fragment 12 and the base member 11. It is understood that in other embodiments, there may be only one limiting portion 124, and the one limiting portion 124 may have a circular ring-shaped sheet shape.

Specifically, the first extension part 1231 may extend outward in the radial direction of the base 11 from one side edge of the elastic arm 122 away from the sleeve part 121 to be away from the base 11 and the heating element 13. The second extension part 1232 may be formed by bending the first extension part 1231, and may extend in a direction away from the base 11 and the heating element 13 in the axial direction of the base 11.
