[0035] The atomizer generally heats the aerosol substrate by using an electric heating element (heating sheet) to atomize the aerosol substrate, and the electric heating element needs to be electrically connected to the electrode through a lead (conductive wire).

[0036] In the related art, the lead is prone to wrinkling and deviating from the predetermined position, which can cause the electric heating element to be deformed under stress, affecting the heating effect of the electric heating element.

[0037] For example, the electric heating element is usually arranged in the atomization cavity of the atomizer, and the lead wire is usually fixed by extrusion through a fixing structure arranged in the atomization support or the base. During the fixing of the lead wire, the lead wire needs to be moved along the axial direction of the atomization cavity, or the fixing structure needs to be moved along the axial direction of the atomization cavity to extrude the lead wire, which may cause the lead wire to wrinkle or deviate from the predetermined position along the axial direction of the atomization cavity.

[0038] To solve the above technical problems, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The atomization support 20 provided by the embodiments of the present application comprises a support body 21, a base 22 and an elastic arm 23. The support body 21 has an atomization cavity 201 for mounting an atomization assembly 30. The atomization assembly 30 comprises a heating sheet 31 and a conductive wire 32 connected to the heating sheet 31. The conductive wire 32 can be electrically connected to a power supply to supply power to the heating sheet 31, so that the heating sheet 31 can heat an aerosol substrate.

[0039] The base 22 is located on one side of the support body 21 along the axial direction of the atomization cavity 201 and is connected to the support body 21. The elastic arm 23 is located on the side of the base 22 away from the support body 21 and is connected to the base 22. The elastic arm 23 and the base 22 have a gap for the conductive wire 32 to pass through, and the elastic arm 23 is used to abut against the conductive wire 32.

[0040] It can be understood that the atomization support 20 provided by the embodiments of the present application can use the elastic arm 23 to abut against the conductive wire 32 and clamp the conductive wire 32 between the elastic arm 23 and the base 22. When installing and removing the conductive wire 32, the elastic arm 23 can be deformed to avoid extruding the conductive wire 32 during installation, which can avoid the conductive wire 32 from wrinkling and deforming and is beneficial to keeping the conductive wire 32 in the predetermined position, so that the heating sheet 31 can be prevented from deforming and the heating effect of the heating sheet 31 can be avoided from being affected to a certain extent.

[0041] Therefore, the atomization support 20 provided by the embodiments of the present application is beneficial to solving the technical problem of the deformation of the heating sheet 31 caused by stress.

[0042] In some embodiments, one end of the elastic arm 23 is connected to the base 22, and the other end of the elastic arm 23 is spaced apart from the base 22. In this way, the elastic arm 23 can be elastically deformed and can be elastically deformed when installing or removing the conductive wire 32, which facilitates the installation or removal of the conductive wire 32.

[0043] In other embodiments, both ends of the elastic arm 23 are connected to the base 22, with a gap between the two ends of the elastic arm 23. This allows the elastic arm 23 to provide better support for the conductive wire 32, improving its stability.
