Jet type spray head double-limiting reversing mechanism

Abstract

The present application belongs to fluid control equipment, in particular, relates to directional controlling mechanism of fluidic sprinkler, comprising a rear reversing mechanism, a front reversing mechanism and a signal stream switching mechanism. A limiting shift rod of the rear mechanism rotate around a locating rod as the center after touching a limiting ring, then realize the reversing of the limiting shift rod. The reverse action of the limiting rod will finally lead a reversing arm to rotate by way of driving a reversing locating block, a rear reversing rod and a front reversing rod to rotate. The rear reversing mechanism, the front reversing mechanism and the signal stream switching mechanism act together, so as to switch a left-side signal stream nozzle and a right-side stream nozzle of a fluidic sprinkler, and bring about the reversing of the rotation direction of the fluidic sprinkler. Directional controlling mechanism of fluidic sprinkler is in a stepping state respectively in the clockwise and the counter clockwise working modes, so that the impact force on a rotary body is small, critical components tend to have a longer working life, an intermediate position does not exist during the reversing of the sprinkler, and the switching of the sprinkler is stable and reliable.
