Add a breeze block to your remote control wall fan

The remote control wall fans on the market have several gears, such as strong, medium, weak, natural wind, and sleeping wind. The natural wind and sleeping windshield fans start and stop. The noise is quite loud, and it is not suitable for use during sleep: in strong, medium, and weak gears. Even in weak gear, the air volume is still too large during sleep! In order to solve this problem, I added a relay, a capacitor, two diodes and a resistor to the circuit (the relay uses the 220V relay in the disinfection cabinet, and its two sets of contacts are connected in parallel: the capacitor withstands a voltage of 400V: the discharge resistor is 100kΩ). Specific connection method: connect the A and B ends to the power supply pin of the colored lights, weld the wire end of the motor weak gear and the connection of the thyristor, and then connect the M and N ends between them. In this way. When you go to bed at night, adjust the fan to the weak gear and press the colored light fan, and it will enter the breeze gear!
