Beschreibung
Zusammenfassung:	The utility model discloses a power supply circuit and a household electrical appliance, the power supply circuit is used for supplying power to an electrical load, and the power supply circuit comprises a switch branch, a capacitor branch, a first resistor branch and a second resistor branch. The switch branch circuit is used for being connected with an input power supply, the switch branch circuit is connected with the first resistor branch circuit, the capacitor branch circuit, the electric load and the second resistor branch circuit, and the first resistor branch circuit is connected with the second resistor branch circuit, the capacitor branch circuit and the electric load. The capacitor branch is charged when the input power supply is powered on, and is discharged when the input power supply is powered off. And the switch branch is switched on based on the discharge voltage of the capacitor branch when the input power supply is cut off. The first resistor branch circuit and the second resistor branch ci
