[0092] The coil disc assembly provided by the present application will be described below in combination with Figures 1 to 6 ​The coil disc assembly comprises a coil disc base 100, a support 200 and a connecting base 400. The support 200 is arranged on the coil disc base 100, and at least part of the support 200 is spaced apart from the coil disc base 100 to form a containing space, and the containing space contains the coil winding 300. By arranging the coil winding 300 in the containing space 101, the support and fixation of the coil winding 300 are realized, and the stable position and form of the coil winding 300 during the working process are ensured. The connecting base 400 is detachably connected to the outer periphery of the coil disc base 100. According to the coil disc assembly of the utility model, the connecting base 400 can be supported to the external structure while ensuring that the coil disc base 100 does not shake or displace during use, thereby ensuring the uniformity and stability of heating. In the present scheme, the coil disc base 100 and the connecting base 400 are arranged in a split body, and the coil disc base 100 and the connecting base 400 can be manufactured separately by suitable manufacturing work to ensure their respective performances.
