Problems solved by technology

[0002] The existing fan mainly has the following two control methods: one is to realize it manually and mechanically; the other is to use the remote control to control the fan remotely. The air supply direction is more appropriate, but the above two methods rely on human hands to control the fan, which is inconvenient to operate
In addition, although a protective net is installed outside the blades, children can still put their fingers into the net due to their thin fingers, which poses a safety hazard.

Abstract

The invention relates to a control circuit for an automatic electric fan. The control circuit comprises a range sensor, a temperature sensor, a voice receiving circuit, a voice identification circuit, a voice feedback circuit, a head shaking control circuit, a PWM speed regulation circuit, a switching circuit and a microprocessor, wherein the voice receiving circuit and the voice feedback circuit are connected with the voice identification circuit; and the voice identification circuit, the temperature sensor, the range sensor, the head shaking control circuit, the PWM speed regulation circuit and the switching circuit are all connected with the microprocessor. The control circuit for the automatic electric fan has the advantages that the fan can be controlled through the voice, the fan speed can be regulated automatically according to outside temperature, and the safety is better.

Description

technical field [0001] The invention relates to a control circuit, in particular to a control circuit for an automatic electric fan. Background technique [0002] The existing fan mainly has the following two control methods: one is to realize it manually and mechanically; the other is to use the remote control to control the fan remotely. The air supply direction is more appropriate, but both of the above two methods rely on human hands to control the fan, which is inconvenient to operate. In addition, although the protective net cover is installed outside the blade, because the child's fingers are relatively thin, they can still put their fingers into the net cover, which poses a safety hazard. Contents of the invention [0003] The purpose of the present invention is to provide a control circuit for an automatic electric fan, which can control the fan through voice, can automatically adjust the wind speed of the fan according to the external temperature, and has better...
