Embodiment Construction

[0037] Traditional electrical equipment is basically equipped with a mechanical switch that can control the on and off of the power supply. When the mechanical switch is turned off, the external power supply does not supply power to the electrical equipment. The device is powered.

[0038] And more and more intelligent electrical equipment configurations are controlled by remote controllers or mobile terminals with control software APP, thereby realizing wireless control of electrical equipment and providing convenience for users to intelligently operate electrical equipment.

[0039] However, the premise that the user can wirelessly control the electric device through a mobile terminal or the like is that the external power supply supplies power to the electric device. If the user turns off the electrical equipment through a mechanical switch and the external power supply no longer supplies power to the electrical equipment, the user can no longer control the electrical equip...

Abstract

The invention discloses a switch detection circuit, and the circuit comprises a detection module, a control module and an electric load. The detection module is used for inputting a power supply voltage at the input end, detecting the flash state of the power supply voltage, and sending a level signal to the control module through the output end when the flash state is detected, wherein the flashstate is a power-off state in which the power-off duration of the power supply voltage is not greater than a preset duration; and the control module is respectively connected with the detection moduleand the electric load, and is used for controlling the switching of the current working state of an electric load when receiving the level signal. Therefore, the switch detection circuit provided bythe invention can realize the function of switching the working state of the electric load by a traditional power switch, and can ensure that the electric equipment is not powered off, thereby bringing convenience to a user to wirelessly control the electric equipment, providing convenience for the user to intelligently use the electric load, and facilitating the popularization and application ofintelligent electric appliances.

Description

technical field [0001] The invention relates to the technical field of electric appliance control, in particular to a switch detection circuit. Background technique [0002] With the development of intelligent control technology, more and more electrical equipment has begun to develop in the direction of intelligent control. For example, smart appliances such as smart lamps, smart TVs, and smart fans can use mobile APP or remote control to wirelessly control their working status. But this premise is to keep the smart electrical appliances in a powered state, and people's inherent habit of using electrical appliances is to control the opening and closing of electrical appliances directly and with smart switch buttons. When the user turns off the smart appliance through the power switch, the smart appliance and the external power supply are powered off, and the wireless control of the smart appliance cannot be performed. Only after the power switch is turned on, can the smart...
