Power supply circuit of garment steamer and garment steamer

A power supply circuit of a garment steamer, comprises a power supply module, a water pump control module, a heating wire control module and a controller;

• wherein an input end of the power supply module is connected to an alternating current (AC) mains, and an output end of the power supply module is connected to the controller;
• two ends of the heating wire control module are respectively connected to the power supply module and the controller;
• wherein the water pump control module further comprises a water pump, a diode D4 and a silicon controlled rectifier (SCR) Q2;
• the silicon controlled rectifier Q2 is used for controlling the turn-on or turn-off of the water pump's power supply circuit;
• one end of the water pump is connected to the power supply module, and another end of the water pump is connected to an anode of the diode D4;
• a cathode of the diode D4 is connected to an anode of the silicon controlled rectifier Q2 anode, and a cathode of the silicon controlled rectifier Q2 is grounded;
• a control electrode of the silicon controlled rectifier Q2 is connected to the controller.
