Water pump with self-cleaning function

Abstract

The invention discloses a water pump with a self-cleaning function, comprising a pump body and a filter device. The filter device comprises a shell; a water inlet channel is formed in the shell; a filter screen is arranged in the water inlet channel and divides the water inlet channel into a raw water cavity and a purified water cavity; a mounting groove is formed in the inner wall of the shell; the filter screen is arranged in the mounting groove; an elastic member is further arranged in the mounting groove; turbulent flow fan blades are arranged in the raw water cavity; pushing protrusions are arranged on the turbulent flow fan blades; an annular sliding rail is arranged on the filter screen; protruding points are arranged on the annular sliding rail; the turbulent flow fan blades are impacted by water flow to rotate so as to drive the pushing protrusions to slide along the annular sliding rail; and the pushing protrusions drive the filter screen to vibrate in the mounting groove when crossing the protruding points. The turbulent flow fan blades are impacted by the water flow, so that the pushing protrusions on the turbulent flow fan blades push the filter screen to vibrate in the mounting groove, large-particle impurities attached to the filter screen are vibrated off, and the situation that the filter screen is blocked by the large-particle impurities and the filtering effect of the filter screen on the water flow is influenced is prevented.

Description

technical field [0001] The invention belongs to the field of water pumps, in particular to a water pump with self-cleaning function. Background technique [0002] At present, during the use of the existing water pumps used to transport liquids, because they do not have the function of filtering, the pumped water flow is relatively turbid, and large particles of impurities such as sediment in the water flow enter and block the inside of the water pump, thereby affecting the water pump. The use of the pump will shorten the service life of the pump. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a water pump with self-cleaning function to solve at least one of the above problems. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: a water pump with self-cleaning function, including a pump body and a filter device arranged at the water i...
