Description

An impact-resistant and anti-blocking water pump

Technical Field

The utility model belongs to the technical field of water pumps, and in particular relates to an impact-resistant and anti-blocking water pump.

Background Art

The water pump is equipped with an inlet and an outlet suction (water) nozzle and an exhaust (water) nozzle. The power source is provided by an electric motor, which drives the water pressure mechanism inside the water pump.
