SPRAY NOZZLE FOR WASHING

Abstract

The invention proposes a spray nozzle for washing, which includes: a straight spray inlet and a spiral spray inlet integrated into a single nozzle body, and thus straight and spiral washing water can be selectively sprayed by natural operation; the lower end of the nozzle forms a spiral washing water, moving circumferentially around the axis and the upper end in direct contact inside the seal ring, thus preventing frictional wear and forming a spiral washing water without frictional force even under low water pressure; and when forming a spiral washing water, the anti-backflow device will close the straight spray inlet, and thus, backflow can be prevented, thereby allowing for the prevention of washing water leakage and stable operation.
