Automotive eccentric wheel style light atomizing pump

The utility model discloses an automotive eccentric wheel style light atomizing pump. The utility model is composed of a plunger rod (1), a pump cylinder (2), a water inlet ball valve and a water outlet ball valve (3 and 4), an air chamber (5), a pressure regulating valve (6), a nozzle (8) and a drive part. A rotary shaft (9) drags the plunger rod (1) to reciprocate through an eccentric wheel (12), the rotational speed of the pump is high, the travel range of the plunger rod is short, the reciprocating motion frequency is high, the working pressure of the air chamber (5) is large, so the work efficiency is high and the atomizing effect is good, and meanwhile, the utility model has the advantages of compact whole structure, small and light size and low manufacture cost, and the utility model is used for sprinkling and water spraying work for farms, forests and fruits.
