Embodiment Construction

[0016] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0017] The driving circuit of a shaded pole motor sleep aid provided by the invention includes a constant voltage adaptation unit 1 and a WiFi circuit 3 , an LED control circuit 4 and a fan motor control circuit 5 electrically connected to a single chip microcomputer 2 .

[0018] Among them, in addition to the inherent transformer, the constant voltage adaptation unit 1 is also equipped with a switching power supply chip for voltage feedback control. Specifically, as shown in the attached manual figure 2 As shown, the primary winding side of the high-frequency transformer T1 is provided with an auxiliary winding, and the AC input voltage passes through the bridge rectifier circuit 101 composed of diodes and the π-type filter circuit 102 to obtain a DC high voltage, and then connected to one end of t...

Abstract

The invention belongs to the technical field of sleep aids, and in particular relates to a driving circuit of a shaded pole motor sleep aid, which includes a constant voltage adaptation unit, a WiFi circuit, an LED control circuit, and a fan motor control circuit respectively connected to a single-chip electromechanical device. In addition to the inherent transformer, the distribution unit is also equipped with a switching power supply chip for voltage feedback control, which provides a more stable working power supply. The structure design of the WiFi circuit, LED control circuit and fan motor control circuit is simpler, while reducing the complexity of the control circuit. , also makes the MCU control the fan speed more reliable, making the generated white noise more stable and comfortable, and the MCU is connected to the two-way fan motor control circuit, which is used as the two gears of the fan motor, making the white noise sleep aid function more humane.

Description

technical field [0001] The invention belongs to the technical field of sleep aids, and in particular relates to a driving circuit of a shaded pole motor sleep aid. Background technique [0002] With the continuous improvement of people's material living standards, people pay more and more attention to their own health, especially the poor quality of sleep, and the diseases caused by insomnia are increasing day by day; according to the survey, people from various regions and different age groups All suffer from insomnia and account for a relatively high proportion, especially people with high work pressure or men or women who are in menopause, and they all have poor sleep quality. How to solve the phenomenon of insomnia and poor sleep quality, most people still choose traditional drug treatment, but the side effects are also relatively large. [0003] Then the white noise sleep instrument breaks the traditional conventional thinking. It uses the fan to create a soothing air ...
