摘要： 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.

摘要： A heating pump includes a pump housing with an inlet, an outlet, a heater, an impeller, and a motor for driving the impeller. The impeller is received in the pump housing. The heater includes connecting heads and a main body for generating heat. The main body is bent into an arc. The pump housing includes a cylindrical sidewall extending in an axial direction of the motor and a top plate sealed to an axial opening of the sidewall. The top plate is made of metal. The heater extends through and is fixed to the top plate. The connecting heads extend to an exterior of the pump housing. The main body is located in an interior of the pump housing and in contact with the top plate.

摘要： 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.
