A control circuit includes a power switch, a heating unit, a water supply unit and a circuit module, wherein the power switch is connected to the heating unit and the water supply unit, and the heating unit and the water supply unit are connected to the circuit module, wherein the circuit module is used to adjust input voltage of different voltage environments to enable the multi-power garment steamer works normally.

A garment steamer and its power supply circuit, wherein the power supply circuit comprises a power supply module, a water pump control module, a heating wire control module and a controller. The power supply module's input and output ends are respectively connected to an alternating current (AC) mains and the controller. The heating wire control module's two ends are respectively connected to the power supply module and the controller. The water pump control module comprises a water pump, a diode D4 and a silicon controlled rectifier (SCR) Q2, wherein the SCR Q2 is used for controlling the water pump's power supply circuit. The water pump's two ends are respectively connected to the power supply module and an anode of the diode D4. The SCR Q2's control electrode is connected to the controller and the SCR Q2's cathode is grounded. The garment steamer includes the said power supply circuit.
