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 multifunctional electric fan control circuit. The multifunctional electric fan control circuit comprises a distance sensor, a temperature sensor, a voice receiving circuit, a voice recognition circuit, a voice feedback circuit, a head shaking control circuit, a PWM speed adjusting circuit, a switch circuit, a displayer and a microprocessor. The voice receiving circuit, the voice feedback circuit and the voice recognition circuit are connected; and the voice recognition circuit, the temperature sensor, the distance sensor, the head shaking control circuit, the PWM speed adjusting circuit, the switch circuit and the displayer are each connected with the microprocessor. The multifunctional electric fan control circuit can control a fan through a voice; the wind speed of the fan can be automatically adjusted according to the temperature of the outside; the safety is good.

Description

technical field [0001] The invention relates to a control circuit, in particular to a multifunctional electric fan control circuit. Background technique [0002] Existing fans mainly have the following two control methods: one is to achieve by manual mechanical; the other is to use remote control to remotely control, first let the fan shake its head, and then control it to stop when the blade rotates to the appropriate direction, so as to obtain It is a more appropriate air supply direction, but the above two methods rely on the operation of both hands to realize the control of the fan, which is inconvenient to operate. In addition, although a protective mesh cover is installed outside the blade, because the fingers of children are relatively thin, they can still insert their fingers into the mesh cover, which poses a potential safety hazard. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a multifunctional electric fan control circuit...
