Specifically, a power supply connection terminal 26 is provided on the base 22, and the power supply connection terminal 26 is electrically connected to the heat generating member 24. The power connection terminal 26 and the heating element 24 can be electrically connected by a conductive circuit, for example, and the embodiment of the present invention does not specifically limit the electrical connection mode between the power connection terminal 26 and the heating element 24.

Alternatively, in the present embodiment, the number of the power supply connection terminals 26 is two, and the two power supply connection terminals 26 are electrically connected to the heat generating member 24, respectively. The number of the feeding electrodes 34 is also two, and the two feeding electrodes 34 are electrically connected. Each of the power feeding electrodes 34 is provided corresponding to one of the power feeding connection terminals 26. Through being connected two power supply connecting terminal 26 with heating element 24 electricity respectively, with two power supply electrode 34 electricity connection, can supply power to heating element 24 after power supply electrode 34 and the contact of the power supply connecting terminal 26 that corresponds, and then promote the stability of heating element 24 work.

Specifically, the base 22 of the heating element assembly 20 is provided with a detection connection terminal 28, and when the detection electrode 52 contacts the detection connection terminal 28, an induction signal is generated. The detection electrode 52 and the power feeding electrode 34 are located on the surface of the electrode holder 32 facing the base 22, and the detection electrode 52 is disposed at a distance from the detection connection terminal 28.

Further, in the present embodiment, the number of the detection connection terminals 28 is two, and the two detection connection terminals 28 are electrically connected.
