Infrared human body induction energy saving disaster preventing switch and socket

Abstract

The invention discloses an infrared ray human body induction energy saving and disaster prevention switch and a socket. An infrared ray human body sensor (1) collects a signal about whether the human body moves about in the effective area of the sensor and generates high level or low level (the sensor is a renewable triggered delay output model, that is, after induced output high level, if a person moves about in the effective area of the sensor in a delay time slice, then output always keeps high level; after detecting every activity in the human body, the sensor automatically postpone a delay time slice and takes the last time activity as the initiation of the delay time). The high/low level controls breakover or blockage of a transistor (2); the breakover or blockage of the transistor controls pick-up or disconnection of a relay (3), and finally controls closure or disconnection of power supply source. Therefore, when people are in a room, power supply is automatic and normal; when no people are in the room and time surpasses the given time delay time, power automatically and immediately cuts off, thus conserving energy and avoiding disaster caused by unexpected short circuit.

Description

technical field [0001] The invention relates to an infrared human body induction energy saving and disaster prevention switch and socket. technical background [0002] Existing switch sockets are normally open and normally closed, that is, each switch must be pressed by people. And in real life, people often forget to turn off the power supply so that the electrical equipment is still in the state of standby power consumption. The Chinese Invention Patent Bulletin discloses an energy-saving timing switch socket with the patent number ZI200420108340.8. When this switch socket is in operation, regardless of whether the electrical equipment is used or not, the switch action is performed within the set switching time. This kind of switch socket not only needs to frequently set the switching time and other cumbersome events, but also cannot realize effective energy saving. Contents of the invention [0003] The object of the present invention is to provide a simple in structu...
