Specifically, when the obtained switched power supply type is the external power supply, the external power supply can provide working voltage for the heating plate because the heating plate is directly connected with the external power supply. If the switched power supply type is obtained as external power supply, it is indicated that the first end of the control power supply is a high level signal, the control unit sends a working control signal to the heating plate to enable the heating plate to start working and control the control power supply and the internal power supply to form a broken circuit, and sends a third control signal to the power supply switching unit to enable the power supply switching unit and the switch power supply to form a closed circuit and enable the power supply switching unit and the internal power supply to be broken circuit. Because external power source connection switching power supply, switching power supply connects the power switching unit, and power switching unit connects heating wire and fan, supplies power for heating wire and fan through external power source promptly.
