Abstract

The utility model provides a self-spraying device with variable angle and flow, wherein a hollow cylindrical connecting pipe is arranged in a cavity of an outer shell, and a water inlet end of the hollow cylindrical connecting pipe is connected with an external water supply system. When water enters the spray head cavity through the water inlet pipe, the fluid pressure pushes the independent nozzles to synchronously and radially move along the arc track of the chute. The clamping block on the outer wall of the nozzle and the nozzle chute form a sliding pair, so that the nozzle is kept axially stable when being pressed and extended. The rubber sealing ring always maintains elastic contact in the expansion process of the nozzle, and forms a dynamic sealing interface with the outer wall of the nozzle through the annular lip. The tail ends of the nozzles penetrate through the corresponding through holes to form independent injection channels, and the extending length of the independent injection channels can be controlled steplessly by adjusting the water inlet pressure, so that the injection angle and the coverage range are changed. The mechanical sealing structure effectively prevents fluid in the cavity from leaking while ensuring the multidirectional adjusting function.
