How does the micro submersible pump in the humidifier work

The working principle of the micro submersible pump in the humidifier is to drive the impeller to rotate through the motor, use centrifugal force to suck water from the suction port, and then spray the water out through the rotation of the impeller to form mist.

Specifically, the working principle of the submersible pump is as follows:

‌After starting, the impeller rotates at high speed‌: After the submersible pump is started, the impeller begins to rotate at high speed, and the liquid rotates with the blades.

Centrifugal force‌: Under the action of centrifugal force, the liquid is thrown away from the impeller and ejected outward.

Pressure increase‌: The speed of the ejected liquid gradually slows down in the diffusion chamber of the pump casing, and the pressure gradually increases.

Liquid discharge‌: The liquid flows out from the discharge pipe at the pump outlet to form mist.

Continuous operation‌: At the center of the blade, a vacuum low-pressure area is formed because the liquid is thrown to the surroundings. Under the action of the atmospheric pressure on the pool surface, the liquid in the liquid pool flows into the pump through the suction pipe. In this way, the liquid is continuously sucked up from the liquid pool and continuously flows out from the discharge pipe.‌
