Energy-saving plug and energy-saving method for timing control on circuit on-off

Abstract

The invention discloses an energy-saving plug for timing control on circuit on-off. The energy-saving plug comprises a multi-syntonic oscillation circuit, a frequency division circuit, a monostable circuit and a relay which are connected sequentially and also comprises a power supply which is connected with the multi-syntonic oscillation circuit, the frequency division circuit and the monostable circuit. According to the energy-saving plug for the timing control on the circuit on-off, only a small, cheap and practical circuit device is added between a plug and a socket of a public electrical appliance under the condition that the internal structure and an electronic circuit of the public electrical appliance are not changed and accordingly the function of the timing control on the timing on-off of a circuit between the public electrical appliance and a 220V power frequency alternating current power supply is implemented.

Description

technical field [0001] The invention relates to the field of energy saving, in particular to an energy-saving plug and an energy-saving method for timing control circuit on-off. Background technique [0002] With the continuous increase of public electrical appliances, the problem of electric energy waste caused by them is becoming more and more serious. Public electrical appliances have high power, are frequently used, and have been powered on for a long time, such as drinking fountains, elevators, street lamps, etc.; and the users of these electrical appliances are a relatively specific group, and their use has certain rules and shows periodicity. Therefore, solving the problem of the low utilization rate of electric energy of these public appliances is of great significance to my country's energy conservation and emission reduction work. [0003] At present, the circuit on-off control of public electrical appliances is mainly completed by adopting methods such as energy-...

Problems solved by technology

However, the use of energy-saving sockets must replace the original sockets, which is difficult to promote in practice

3) Most energy-saving plugs are similar to energy-saving sockets. In recent years, a new design concept of energy-saving plugs has emerged, that is, only a small and practical circuit device is added between the plug and the socket of the electrical equipment, so as to realize the connection between the electrical equipment and the socket. Timing on-off between power supplies, however, there are ambiguities in product positioning, timing circuit implementation, cost, etc.
