[0030] A power supply circuit, wherein the input terminal of the power supply circuit is connected to the first output terminal and the second output terminal respectively, and the output terminal of the power supply circuit outputs DC12V and DC5V respectively.

[0031] The main control circuit includes a first switching circuit, a main control chip, and peripheral circuits of the main control chip; the input terminal of the first switching circuit is electrically connected to DC5V, and the output terminal of the switching circuit is electrically connected to the input terminal of the main control chip.

[0034] The power supply circuit converts 220V AC mains power into DC 12V and DC 5V, allowing the circuit to provide multiple voltage supplies. When a switch signal is input to the switch circuit, such as a left or right swaying signal, the main control chip receives the left or right swaying control signal from the switch circuit, identifies the signal, and then outputs a control signal to the drive circuit.

[0037] The circuit uses a rectifier bridge to convert 220V AC mains power to DC 12V, and then uses a 78L05 chip to convert the DC 12V voltage to DC 5V voltage. This allows the circuit to be powered by three different voltages: 220V AC mains power, DC 12V, and DC 5V, thus facilitating power supply to the corresponding circuit.

[0039] When a control signal is input to switch K1, the MDT2005 chip processes the working state and receives a signal from sensor 1. The MDT2005 chip then identifies and judges the signal. If the signal is determined to be a control signal, it is output through pin 10 of the MDT2005 chip and input through pin 1 of the ULN2003A chip. The ULN2003A chip outputs from pin 16.

At the same time, relay RELAY2 is energized, and normally open switch S2 is closed, so that AC220V is input to the oscillating motor M3 through normally open switch S2, making the oscillating motor M3 work, that is, realizing the up and down oscillation of the appliance.

[0041] When sensor 3 inputs a signal, the MDT2005 chip identifies and judges the signal. If it is judged to be a control signal, the control signal is output through pin 12 of the MDT2005 chip and input through pin 3 of the ULN2003A chip. The ULN2003A chip outputs from pin 14. At the same time, relay RELAY3 is energized, and normally open switch S3 is closed, so that AC220V is input to the oscillating motor M1 through normally open switch S3, making the oscillating motor M1 work, that is, realizing the rotation of the fan on the appliance.

[0042] Specifically, sensor 1, sensor 2, and sensor 3 can be Hall effect sensors, or they can be other sensing switches as needed.
