Handheld flushing pump

Abstract

The invention discloses a handheld flushing pump, mainly comprising a pump body, a piston, an eccentric shaft, a motor, an input check valve and a drainage check valve, wherein the eccentric section of the eccentric shaft is inserted into a groove at the waist part of the piston, and when the motor drives the eccentric shaft to rotate, the piston moves to and fro so as to suck and drain off water. The pump body and the eccentric shaft are both directly mounted on the micro motor, so that handheld flushing pump is compact in structure, light in weight, small in size and convenient to move, and can be used at all sites with civil electricity; according to the character of pumps, the handheld flushing pump belongs to displacement pumps, has higher self-suction capacity, can perform flushing by only inserting a suction pipe into a water bucket, does not need to stop working even water in the water bucket is used up, and still can suck water for flushing by filling water into the water bucket, thus providing the capability of self-restoring after running out of water; furthermore, the pump has very high efficiency which generally can reach more than 70%. The handheld flushing pump has the advantages of compact structure, light weight, convenience to move, strong self-suction capacity, self-restoring after running out of water, and utilization of civil electricity.

Description

technical field [0001] The present invention relates to a positive displacement pump, especially a portable flushing pump. Background technique [0002] Washing pumps have a wide range of uses in various industries. Cleaning various places is inseparable from washing pumps, such as cleaning roads, floors, cars, motorcycles, etc.; most of the existing washing pumps are fixed, small, capable Flexible and mobile small flushing pumps are mostly three-piston pumps, which transmit the power of the motor to the crankshaft through the pulley, and the crankshaft drives the three plungers to reciprocate. They are generally installed on mobile vehicles and use 380V power; It is not suitable for families, fairs, schools, commercial places, especially family farming and family animal husbandry. Contents of the invention [0003] The object of the present invention is to provide a portable flushing pump with compact structure, light weight, convenient movement, strong self-priming abil...
