Abstract

The invention provides an anti-electric-shock power socket safety device which comprises a touch induction metal plate, an induction signal detection circuit, a safeguard control circuit, an alternating current relay and a power circuit. The touch induction metal plate is fixed to the inner side of a power socket face plate and connected with the input end of the induction signal detection circuit, the output end of the induction signal detection circuit is connected with the safeguard control circuit, the safeguard control circuit controls the normally-closed electric shock of the alternating current relay to be opened and closed, and the power circuit provides a power source for the induction signal detection circuit and the safeguard control circuit. The anti-electric-shock power socket safety device can perform the safeguard function on use of a power socket, and meanwhile is high in reliability and simple in structure.

Description

technical field [0001] The invention belongs to the field of power socket safety protection, in particular to an electric shock-proof power socket safety protection device. Background technique [0002] The power socket is a necessary mains power supply port in the family. Since the power socket is usually charged all the time, non-standard power-taking methods may cause users to get an electric shock, posing a safety hazard. For example, toddlers and children usually try to plug and unplug the electrical plugs on the power sockets because of their curiosity; in kitchens, bathrooms and other places where water is convenient, users usually plug and unplug the electrical plugs connected to the power sockets after washing their hands but not dry. Kitchen and bathroom appliances on the plug. It is possible to directly or indirectly (through liquids such as water) accidentally touch the charged plug metal piece. There are some electric shock protection products for infants and...
