[0021] A mounting hole 9 is provided on the heat conducting plate 2, and an insulating member 8 is pressed into the mounting hole 9. The insulating member 8 is elastic, and the insulating member 8 and the mounting hole 9 have an interference fit, so that the entire heating device 3 is pressed tightly into the mounting hole 9; the temperature probe 10 extends into the mounting hole 9 to detect the temperature value of the heating device 3.

[0022] The heating component 7 is a PTC ceramic heating sheet, the insulating member 8 is a high temperature resistant insulating glue, and the heat conducting plate 2 is made of aluminum alloy material or stainless steel material.
