Description

An intelligent power-off socket

technical field

The utility model relates to a socket, in particular to an intelligent power-off socket.

Background technique

At present, most of the sockets and sockets on the market are non-intelligent. People generally do not cut off the power of the electrical appliances directly when they are connected to the sockets. Therefore, the electrical appliances are always in the standby state. If the socket is connected at this time, Electrical appliances will generate standby power, resulting in waste of electric energy. The power of a commonly used desktop computer is 3..5W after it is turned off, and it is 3.7W when it is included in the sleep state. The standby power of a TV set for home use is between 3-5W. Standby for a long time will cause various problems such as accelerating the aging of electrical appliances, shortening the service life of electrical appliances, and increasing potential safety hazards. Nowadays, power sockets are pervasive in people's production and life. Therefore, the research and application of independent intelligent power-off of power metering socket will have positive practical significance for the safety of electricity consumption and energy-saving use of power appliances.

At present, the traditional plug-in strips are the mainstream in the market, and the other part is to install overload protection and other means on the traditional plug-in strips. This type of plug-in strips is not intelligent, and it is very rigid when used.

There are also most timing-type smart sockets, which have great limitations in realizing intelligent power-off by setting the working time, and the time of the timer needs to be manually adjusted each time it is used.

There is also a relatively advanced smart power-off socket. The user uses a mobile phone to control the switch of the socket through wifi. This type of switch still needs to be operated by a person and cannot automatically cut off the power.
