There are two reasons:
1, the machine in the working process, there are fans and atomization board, atomization board through high-frequency vibration fog, fan rotation to blow out the fog, the transport process may be the fan shifted, so there is a slight noise.
2, when the humidifier is used, the water in the water tank has the process of replenishing the bottom atomization area. The atomization sheet will turn the water mist into water mist and send it out of the body. The small fog in the atomization is blown out, and the larger fog condenses into water drops and falls back to the sink, producing water sound. Humidifiers have a lot of noise. The reasons may be:
1. The lack of lubrication of the fan, a long time, the lubricant will slowly become less denaturated;
2. Fan bearing clearance gradually increases due to use, resulting in shaking and jitter;
3. The fan shaft is damaged.
4. The fan bearing is rusted by moisture, and the friction produces slag;
5. Fan bearings enter dust and debris;
May be caused by the humidifier fan without lubricating oil;
2, it may be caused by the humidifier fan bearing dust;
3. It may be caused by problems with the humidifier fan hardware, such as fan bearing wear, excessive clearance, and rust.
Humidifier noise solution: Open the back cover and remove the small fan, you can put on the lubricating oil, or go directly to the computer market to buy a replacement. The humidifier has been used for some time to produce noise, which is mainly caused by the fan inside. The reason why the fan usually produces a large buzz when it is running is mainly due to the lack of lubricating oil in the fan rotor parts. Of course, usually the motor may be quieter after a period of time.
