Abstract

A multi impact type water mist nozzle includes a body (1) and multiple impact needles (2). Along the axis of the body (1) from the top downward are a water inlet connection (5), a main channel (4) and multiple branch channels (3). The number of the outlets (3a) of the branch channels (3) is the same as the number of the impact needles (2). The impact needles (2) are U-shaped and distributed evenly coaxial with the axis of the body (1). One end of each impact needle (2) is a fixing end (2a) which is stamped at the lower surface of the body (1), the other end of the impact needle (2) is an impact end which is perpendicular to the axis (3b) of each branch channel (3). The outlets (3a) of the branch channels (3) are evenly distributed on an imier deflective ring (7) and an outer deflective ring (6). The ironer and outer deflective rings are circular ring surfaces coaxial with the axis of the body (1) and adhered together. The deflective angles of the inner and outer deflective rings are not equal.
