Disclosed is a jet type spray head double-limiting reversing mechanism, comprising a rear reversing mechanism, a front reversing mechanism and a signal stream switching mechanism. A limiting shift rod (1) of the rear reversing mechanism rotates by taking a locating rod (8) as the centre after touching a limiting ring (2), and the reversing of the limiting shift rod is realized. The reversing of the limiting shift rod will drive a reversing locating block (10), a rear reversing rod (11) and a front reversing rod (25) to rotate, and finally a reversing arm (40) is driven to rotate. The rear reversing mechanism, the front reversing mechanism and the signal stream switching mechanism are mutually fitted, so as to switch a left-side signal stream nozzle and a right-side signal stream nozzle of a jet type spray head, and realize the reversing of the rotation direction of the jet type spray head. The jet type spray head double-limiting reversing mechanism is in a stepping state respectively in the clockwise and the counter clockwise working modes, such that the impact force on a rotary body is small, service life is long, an intermediate position does not exist in the process of reversing a spray head, and the switching of the spray head is stable and reliable. |
