Zusammenfassung: | A pump includes a seat unit, a motor unit and a leak detector. The motor unit includes a rotor, an inner case body, an outer case body and a stator. The inner case body has an inner end wall. The outer case body is sleeved on the inner case body and has an outer end wall. The outer end wall cooperates with the inner end wall to define a liquid-receiving space therebetween. The leak detector is disposed on one side of the outer end wall opposite to the liquid-receiving space and includes a sensor for detecting the change of the electrostatic capacity between the liquid-receiving space and the sensor. |
