A heat collecting pump includes: a flow guide member, including a flow guide body and a flow guide blade, wherein the flow guide blade is disposed on an outer peripheral wall of the flow guide body; a heating member, disposed on a periphery of the flow guide member and spaced apart from the flow guide blade. The flow guide blade enables water to flow along the outer peripheral wall of the flow guide body to form a first whirlwind flow and to further form a second whirlwind flow in a gap between the heating member and the flow guide blade. Projections of velocity directions of the first whirlwind flow and the second whirlwind flow on a reference plane perpendicular to the axial direction of the flow guide body are in opposite directions; and the second whirlwind flow removes bubbles gathered on the heating member.

Heat collecting pump and domestic appliance

A heating pump includes a driving electric motor; a pump case, wherein a pump cavity and a heating cavity are defined in the pump case, the pump cavity and the heating cavity are roughly arranged side by side in an axial direction and are in communication by means of a communication channel, and a water inlet and a water outlet are formed in the pump case; an impeller arranged in the pump cavity; and a heating member arranged in the heating cavity. Therefore, not only is the size of the heating pump favorably reduced, the impeller may also be prevented from being radiated at a temperature by the heating member, such that the premature aging of the impeller may be prevented, and thus, the usage performance of the heating pump may be improved.

Provided is a sweeping robot. The sweeping robot includes a chassis and a jet dust raising structure, and the jet dust raising structure is installed on the chassis, the jet dust raising structure has an air inlet, an air outlet and a jet channel connected to the air inlet and the air outlet, the air inlet is configured for air flow into the jet channel, the air outlet is located on a front side of the brush suction port of the sweeping robot.

Sweeping robot

A counter-rotating fan, comprising two impellers and a motor. The motor is used for driving the two impellers to rotate. The two impellers are axially spaced apart from each other, and are divided into a first-stage impeller and a second-stage impeller. When the counter-rotating fan operates, airflow is blown to the direction of the second-stage impeller by means of the first-stage impeller. At least one impeller has turns of blades arranged in the radial direction of the impeller. Blades of each turn are spaced apart from each other around a hub of the impeller, and a spacer ring is connected between two adjacent turns of blades. The counter-rotating fan is stable in rotation and good in cooling effect, it is not easy to deform, and the wind is strong in the center.
