[0006] As an optimization, a controller is provided outside the thermistor, and the controller and the thermistor are signal connected. The temperature of the heating column can be detected by the thermistor, so that a signal is transmitted to the controller when the temperature reaches the set value, and the power switch is cut off by the controller, thereby achieving the function of automatic control switch.
