Title:
SPRAY NOZZLE FOR WASHING
Document Type and Number:
WIPO Patent Application WO/2023/113207
Kind Code:
A1
Abstract:
The present invention relates to a spray nozzle for washing, in which: a linear spray inlet and a spiral spray inlet are integrally formed in one nozzle body, and thus, linear and spiral washing water can be selectively sprayed by operating organically; the lower end of a nozzle tip, which forms the spiral washing water, moves circumferentially around the axis, and the upper end makes linear contact within a packing, thereby preventing abrasion caused by friction and forming the spiral washing water without frictional resistance even in the case of weak water pressure; and when forming the spiral washing water, a backflow preventing member closes the linear jet inlet, and thus, backflow can be prevented, thereby enabling leakage prevention of washing water and a stable operation.
