[0007] The stator is sealed through the coating mechanism to reduce the influence of water vapor on the stator. Then, the stator drives the rotor of the electronic water pump to operate, and the volute conducts the liquid to realize the transportation of the liquid, thereby improving the practicability of the equipment.
