[0027] The cover plate 2 is made of copper material, the base 1 is made of heat-insulating material, a sealing strip 16 made of high-temperature resistant material is fixed around the top of the base 1, and clearance holes 7 are integrally provided on the left and right sides of the insulating strip 302. The clearance holes 7 are through-holes, and the outer side of the wedge block 502 is a sloped design. The user first aligns the limiting hole 303 at the insulating strip 302 with the guide pin 4, and then covers the limiting hole 303 with the guide pin 4, so as to place the electric heating film 301 in a flat state inside the base 1, and then inserts the mounting plate 601 through the clearance hole 7 into the mounting hole 501, so that the mounting plate 601 applies a squeezing force to the inclined surface of the wedge block 502, and the two wedge blocks 502 move towards each other, and the spring 503 is deformed until the wedge block 502 and the plug hole 602 overlap each other, and the wedge block 502 is inserted into the plug hole 602 by the rebound force of the spring 503, thereby locking the state of the base 1 and the cover plate 2.

At the same time, the temperature sensor 9 monitors the temperature generated by the electric heating film 301 when it is working. When the electric heating film 301 needs to be replaced, the user inserts a finger into the placement hole 14, and then drives the mounting hole 501 together with the circular plate 13, the rotating pin 11 and the gear 12 to rotate 45 degrees clockwise. At this time, the gear 12 controls the rack 10 to drive the wedge block 502 to disengage from the socket 602, and the spring 503 is deformed. The user then uses the other hand to separate the cover plate 2 together with the mounting plate 601 from the base 1, and then replaces the electric heating film 301.
