Problems solved by technology

[0002] The working modes of various range hoods on the market are roughly the same, and only a few brands of range hoods have a delay function, which causes a lot of inconvenience during the use of the range hood. It is necessary for the range hood to continue to work for a period of time to exhaust the range hood. However, most range hoods do not have a delay function; Running for a long time will cause the motor to wear for no reason and waste some unnecessary power; Fire and other safety accidents

Abstract

The invention discloses a microwave induction type rang hood power outlet. The microwave induction type rang hood power outlet is characterized by comprising a 220V alternating current power supply, a 12V half-wave rectification voltage-stabilized power supply, a microwave induction circuit, a signal identification and amplification circuit as well as a level signal delaying and rang hood power outlet driving circuit, wherein a microwave induction module IC1 in the microwave induction circuit adopts the model of TWH9428; an integrated circuit IC2 in the signal identification and amplification circuit adopts the model of TWH9429. One microwave induction type rang hood power outlet is designed for a common range hood and can automatically detect whether a human body works nearby the range hood in a microwave induction manner, alternating voltage in the rang hood power outlet is disconnected completely in a few minutes once the human body gets far from the range hood, and the automatic human body detection function and safe electricity utilization of the common range hood are realized.

Description

technical field [0001] The invention belongs to the field of electronic technology and power saving technology, and relates to a microwave induction type range hood power socket. Background technique [0002] The working modes of various range hoods on the market are roughly the same, and only a few brands of range hoods have a delay function, which causes a lot of inconvenience during the use of the range hood. It is necessary for the range hood to continue to work for a period of time to exhaust the range hood. However, most range hoods do not have a delay function; Running for a long time will cause the motor to wear for no reason and waste some unnecessary power; Fire and other safety incidents. [0003] The present invention designs a microwave induction type power socket for range hoods, which can automatically detect whether there is a human body working near the range hood by means of microwave induction. Once the human body is far away from the range hood, the AC ...
