Abstract: A liquid pump includes a housing, a motor fixed in the housing, and an impeller driven by the motor. The motor includes a stator and a rotor rotatable relative to the stator. The impeller is connected to a rotor of the motor. The housing includes a guide wall surrounding the stator, and a guide face extending outwardly from an outer surface of the guide wall to guide a liquid flowing to the guide wall to flow in a direction away from the stator, thus ensuring the electrical safety of the liquid pump.

Abstract: A rotor, motor, pump and a cleaning apparatus are provided. The rotor includes a shaft and two magnets fixed to the rotary shaft. Each magnet comprises a radial outer surface, a radial inner surface, and two connecting surfaces that connect the radial outer surface and the radial inner surface at opposite ends of the magnet. The radial outer surface has an arc section. The radial inner surfaces of the two magnets cooperatively define an inner bore for the shaft to pass therethrough. A ratio of a pole arc angle of each magnet to a 180-degree angle is in the range of 0.75 to 0.95.

Abstract: A cover assembly and a brushed motor are provided. The cover assembly includes a mounting portion and a flow guide portion. The mounting portion defines a first opening through the mounting portion along an axial direction of the motor. The flow guide portion includes a top wall disposed at one end thereof away from the mounting portion along the motor axial direction. The fluid guide portion defines a second opening extending to an inner wall surface of the top wall in the motor axial direction. The first opening and the second opening are in flow communication with each other. The flow guide portion further defines a winding flow passage. The flow passage has an inner inlet in flow communication with the second opening and an outer outlet in flow communication with an outside environment. The present invention facilitates absorption of the motor noise and hence reduction of the output noise.
