portable air purifier.What to do if the humidifier is broken

　　1. The humidifier does not produce fog

　　Solution: Plug in the power and turn on the humidifier. If you find that the fan is not running, then remove the fan and measure the switch with a 12V voltage. If the humidifier works, it means the fan is damaged. It is wise to replace the fan with a new one.

　　2. The humidifier does not respond when powered on

　　Solution: Connect the power supply first, and if there is no response when measuring 36V or 12V, it means that the power switch has malfunctioned. Open the power switch again and check. If there is some blackening in the rectifier, it means the diode is damaged. Replace it with a new one and the problem will be resolved.

　　3. Weak water vapor atomization

　　Solution: First, use voltages of 36V and 12V to measure whether the humidifier can be used normally. There is no breakdown phenomenon in Q2, and there is no blackening of any resistor or capacitor components. But it was found that there was a lot of dirt on the water tank and the walls of the water tank, and there was also a layer of dirt on the surface of the transducer. At this time, after the specialized cleaning agent of the humidifier was thoroughly cleaned, and then powered on, the atomization effect of the humidifier should be able to return to normal.
