A child safety wall power socket

Abstract

The invention relates to a child-safety wall power socket, which comprises a shell and a control panel, wherein the shell is divided into a front panel and a rear housing, wherein the front panel is provided with a power output jack, a pyroelectric infrared sensor and a power indicator light; the rear housing is provided with a power input terminal; the control panel is arranged in the shell and is provided with a power conversion module, a load access judgment circuit, a load current judgment circuit, a human body approach judgment circuit and a logic control drive circuit; the human body approach judgment circuit can sense that a human body approaches to the socket; and the load access judgment circuit solves the contradiction problem that a load current can be detected only in presence of power output, and a power supply can be output only when judging the load access. The child-safety wall power socket provided by the invention can start the power output only when nobody approaches and the load is accessed through logic judgment on human body approach, load access and energized output; and the risk that a human body, especially a child accidentally touches the power socket is effectively prevented.

Description

technical field [0001] The invention relates to the field of household safe electricity utilization, in particular to a child-safe wall power socket. Background technique [0002] Household electricity is inseparable from the power socket, and a plurality of power sockets are generally installed on the wall in the living room, which can be used for household appliances. However, if there are less sensible and more active children in the family, they may touch the power socket with their hands, or insert a metal wire into the power hole, which may cause electric shock. In order to avoid the occurrence of misfortunes, various forms of children's electric shock-proof sockets have appeared on the market or in publicity. Some use safety doors, safety covers, protective covers, safety locks, etc. to prevent children from touching the socket, some use absorbent fiber material sleeves to prevent wet fingers from touching the socket, and some claim to use induction contacts and indu...

AI Technical Summary

Problems solved by technology

[0003] For devices such as safety doors and protective covers, it is still impossible to prevent children from touching the socket when they are loose, falling off or opened; for the assumption of using water-absorbing materials, etc., it is impossible to explain clearly how to prevent human body from electric shock; Using inductive contacts, inductive switches, etc., will also trigger the power output when other metal materials penetrate into the power socket. Therefore, these electric shock-proof sockets cannot completely and reliably prevent the human body, especially children, from accidentally touching the power socket.
