Abstract: A heating pump includes a pump body and a driving motor. The pump body includes a pump housing with a water inlet and a water outlet, a heating member fixed in an interior of the pump housing, and an impeller connected with the driving motor. The heating member includes fittings and a heating coiled pipe connected between the fittings and bent into an arc. The impeller is disposed at an upper part of the pump housing, one end of the driving motor is disposed adjacent the impeller, and the heating coiled pipe circles around a radial side portion of part of the driving motor. The heating pump has a rational design and high heat exchange efficiency. The safety auxiliary motor has a low requirement for power. The axial size of the water pump is significantly reduced.

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.
