Abstract
The utility model provides an energy-saving safety socket for a household electric appliance. The utility model is mainly composed of a power plug, a relay switch, jacks and a control circuit. The control circuit comprises a voltage-reducing rectification filtering power supply circuit, an electrical inductance sampling circuit and a relay. The current is received from the electrical inductance, and the change of the current is utilized to control a main return circuit to be switched on or switched off; thus, when the current reaches to a definite value, the main return circuit can be switched on, and an electric appliance can be guaranteed to do normal work; when the electrical inductance is not provided with the current or is provided with very small current, the relay is released, and the relay switch has instant voltage to pass through a coil; thus, the relay switch is switched off, and the main power supply is switched off. The utility model has the advantages of simple structure, convenient use and low cost. When the utility model is used, the power consumption of the socket is not generated.
Description
