Then, the temperature display 13, the silicone rubber heating wire 23, the temperature sensor 27, the power interface 32 and the temperature control board 37 are electrically connected through wires to complete the wiring work. Then, the side panel 4 is placed on both sides of the front panel 2, so that the first plug blocks 11 on both sides of the front panel 2 are inserted into the second plug holes 17 of the corresponding side panel 4. Then, the heat conducting plate 25 is inserted from the fixing groove 40 on the side panel 4, so that one side of the heat conducting plate 25 is in contact with the front panel 2.
