In order to solve the above problems, some people have designed a smart socket. When the current current of the electrical appliances connected to the main socket is lower than a certain value of the normal working current, it will automatically cut off the power supply of the peripherals connected to the controlled socket. However, this design The disadvantage is that the sensitivity is not high enough. For example, when the working current of the electrical appliance connected to the main socket is relatively small, the current in the shutdown or standby state is very different from the working current. At this time, it may not be detected and cannot be reached. The function of cutting off the power supply of the controlled socket, and the current smart socket needs to manually press the learning button to detect and record when detecting and recording the working current of the main control socket, and it cannot realize automatic processing, which is not convenient to use. the

In view of the above-mentioned defects and existing problems, it is necessary to propose new improvements to the design of the existing smart socket. the
