The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

In this embodiment, a conductive fixing assembly includes an insulating fixing base 1, a conductive elastic member 2 and an electrothermal film 3, where the conductive elastic member 2 has good elasticity and structural strength, so that the conductive elastic member 2 can generate elastic deformation under the stress state.

The conductive elastic piece 2 is connected with the insulating fixing seat 1, the conductive elastic piece 2 is provided with a free abutting part 21, and the free abutting part 21 is used for abutting against the electrothermal film 3 so as to fix the electrothermal film 3 on the pot body 4. That is, the conductive elastic member 2 is mounted to the insulating fixing base 1, so that one end of the conductive elastic member 2 is fixedly connected to the insulating fixing base 1, and the free abutting portion 21 at the other end is abutted against the outer surface of the electrothermal film 3, thereby realizing the purpose that the electrothermal film 3 of the conductive fixing assembly is fixedly abutted against the pot body 4 through the conductive elastic member 2.

In addition, during the process of installing the conductive elastic member 2 to the insulating fixed seat 1, the free abutting portion 21 of the conductive elastic member 2 makes abutting contact with the surface of the electrothermal film 3, and at the same time, the conductive elastic member 2 generates tiny deformation. Defining the free abutting portion 21 as an abutting contact surface of the free abutting portion 21 for contacting one side surface of the electrothermal film 3, the abutting contact surface will eventually finish overlapping/fitting with the outer surface of the electrothermal film 3 with deformation of the conductive elastic member 2.
