How does a micro submersible pump work in a humidifier?
Micro submersible pumps are usually used as core components in humidifiers, providing the necessary pumping force for the humidifier to atomize moisture.
Here's how a mini submersible pump works in a humidifier:
1. After powering on, the motor part starts to work, generates a magnetic field and drives the iron core to rotate.
2. The rotation of the iron core drives the impeller of the pump part to rotate. The rotation of the impeller generates centrifugal force and sucks water into the pump from the water inlet.
3. After the pump casing and impeller suck the water from the water inlet, it sprays the water through the nozzle. The design of the nozzle can make the water spray out in the form of fine mist, which increases the humidity of the air.
4. Thermal protector and overload protector can protect the motor and pump parts from damage.
This working method of the micro submersible pump can provide a stable and efficient moisture atomization effect for the humidifier, while extending the service life of the humidifier.

How to evaluate the efficiency of micro submersible pumps in humidifiers?
The efficiency of micro submersible pumps in humidifiers can be evaluated through the following aspects:
1. Flow rate: The flow rate of the micro submersible pump should match the needs of the humidifier. If the flow rate is too low, the humidifier may not be able to achieve the required atomization effect; if the flow rate is too high, it may cause waste and even cause damage to the humidifier.
2. Power: The power of the dc submersible pump should match the needs of the humidifier. If the power is too low, it may not be able to provide enough pumping power, affecting the effectiveness of the humidifier; if the power is too high, it may cause waste or even cause damage to the micro submersible pump.
3. Working pressure: The working pressure of the micro submersible pump should match the needs of the humidifier. If the working pressure is too low, it may not provide sufficient atomization effect; if the working pressure is too high, it may cause damage to the humidifier and micro submersible pump.
4. Noise: The noise of the micro submersible pump is also a factor that needs to be considered. If the noise is too loud, it may affect people's lives and work.
