Abstract
A heating apparatus includes a power source, a heating unit, and a control unit. The control unit includes a transistor and a thermal resistor. The transistor is connected between the power source and the heating unit to control the power source to provide power to the heating unit. The thermal resistor is connected to the transistor. A resistance value of the thermal resistor changes along with ambient temperature to turn on or off the transistor to control the power source to provide power to the heating unit according the ambient temperature.
