  • Patent number: 10544787
    Abstract: A pump device includes a casing, an impeller, a base, and a motor. The casing includes a pump chamber, and an inlet and an outlet. The impeller is accommodated in the pump chamber. The motor is connected to the casing for driving the impeller to rotate and includes a rotor chamber for receiving a rotor. The base is disposed between the impeller and the motor and includes an accommodating groove having an inlet port in communication with the rotor chamber to allow fluid in the pump chamber to enter into the rotor chamber. In the pump device, precipitation has been performed to fluid in the accommodating groove before the fluid enters into the rotor chamber, thus the impurity particles can be prevented from entering into the rotor chamber, thereby prolonging the service life of the pump device.

  • Patent number: 10418883
    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.
