Energy-saving method and energy-saving device for electronic product

Abstract

The invention discloses an energy-saving method and energy-saving device for an electronic product. A switching module is disposed between a power supply and a power utilization circuit. A time delay switching-off module is disposed at a bypass of the switching module, and the output end of the time delay switching-off module is connected to the control end of the switching module. The control end of the switching module receives a control signal or a working state signal of the power utilization circuit, wherein the control signal or the working state signal of the power utilization circuit is coupled to the control end of the switching module. When there is no control signal or the working state signal is 'not working', there is no signal transmitted to the control end of the switching module, and the control end of the switching module is controlled by the time delay switching-off module, and the switching-off operation is delayed. When there is the control signal or the working state signal is 'working', there is a signal transmitted to the control end of the switching module, the switching module is controlled by the signal, the time delay switching-off module does not plays a role and the power utilization circuit works normally. The device can effectively reduce the static energy consumption current of the electronic product, and prolongs the service time of a battery.

Description

technical field [0001] The invention relates to an energy-saving method in the field of electronic technology, in particular to an energy-saving method for electronic products, and also relates to an energy-saving device for electronic products. Background technique [0002] With social development and technological progress, electronic products have penetrated into all areas of people's lives. Modern people are in contact with electronic products all the time, and no one can carry out modern life without electronic products. [0003] Current electrical and electronic products all require electricity to work as energy, ranging from large electrical products that use mains power, such as household appliances such as televisions, washing machines, and refrigerators, to electrical control products used in industry. It is as small as the mobile personal digital devices such as battery-powered portable wireless phones, tablet computers, and game consoles that we usually use, and ...

Problems solved by technology

If the quality of the electronic device itself is poor, the quiescent current may be large

In any case, if a certain electronic product is in this standby state for a long time, the power of the electronic product powered by the battery will also be completely consumed.

Not conducive to energy saving of electronic products

[0005] Although the above state can be solved by turning off the battery power supply, due to the inherent short life and poor reliability of mechanical switches, current electronic products have basically abandoned the practice of using mechanical switches directly as power switches, and set the power switch to In the form of an electronic switch controlled by a small micro button
