[0030] In this embodiment, a number of heating pin seats 31 are evenly distributed on the bottom surface of the circuit control board 3, and the heating pin seats 31 are electrically connected to the corresponding heating pin heads 67 in a plug-in manner. Through the arrangement between the heating pin seats 31 and the heating pin heads 67, when a failure occurs in the graphene electric heating plate 66, the damaged graphene electric heating plate 66 can be disassembled and replaced separately.
