Energy-saving power supply

Abstract

The invention provides an energy-saving power supply, comprising a socket, a power cord and at least one USB (universal serial bus) conducting wire, wherein the socket is provided with at least one group of jacks and internally provided with a relay; one end of the power cord is provided with a power connector and the other end of the power cord is connected to the relay of the socket so as to supply power for each group of jacks; the relay controls current of the power cord which flow to each group of jacks; and one end of each USB conducting wire is provided with one USB connector and the other end of each USB conducting wire is connected to the relay, so that the relay starts and the power cord and each group of jacks form a circuit when the current passes through the USB conducting wires, and the relay is closed and the power cord and each group of jacks are in open circuit state when the USB conducting wires stop current transmission. By the adoption of the energy-saving power supply, after main electrical equipment connected with the USB conducting wires is turned off, other auxiliary electrical equipment connected to the socket are turned off at the same time, thus the aim of saving electricity is achieved.

Description

technical field [0001] The present invention relates to a power supply, in particular to an energy-saving power supply capable of shutting down other connected auxiliary appliances at the same time when the connected main electric appliance is turned off. Background technique [0002] Electricity is an indispensable source of energy in modern life. It not only provides lighting for human beings, but also enables various transportation systems, information systems, and electrical products driven by electricity to work well, and helps human beings improve their lives. quality. [0003] However, in this era of massive energy consumption, we are also facing the problem of energy shortage. In addition to finding alternative energy sources, how to save existing resources is also one of the active means of various countries; for example, in Taiwan Province of China, the government is There are many subsidies for users who change general electrical appliances to energy-saving appli...

AI Technical Summary

Problems solved by technology

[0004] Although replacing general electrical appliances with energy-saving appliances can achieve the effect of saving electricity, if the electrical appliances are not turned off immediately after use, and the electrical appliances are kept in standby mode, the power consumption will be even more considerable

Moreover, there are many electrical appliances used in offices or home stores, such as computers, computer screens, printers, speakers, desk lamps, fluorescent lamps, wireless network base stations, digital electronic billboards, etc. Generally, users usually just turn off the computers they are using and forget about them. Turn off other electrical appliances, resulting in power loss

Especially in offices, office workers usually have their own computers and shut them down after use, but public computers, printers, scanners, etc. are left unattended, resulting in power loss, and accidents where wires may go off fire
