Embodiment Construction
[0014] see figure 1 , The jet spray nozzle using the jet nozzle reversing control mechanism of the present invention is composed of four parts such as a rotary sealing mechanism, a flow channel, a jet element, and a reversing control mechanism. The key part of the present invention is the reversing control mechanism, which is mainly composed of Figure 4 Shown commutator 6, limit device (comprising figure 1 Positioning block 8, positioning bolt 10, hex nut 11, reversing shift fork 13, gear rod 14, block 17, connecting bolt 18, limit ring 19), joint (including Figure 4 Reverse interface II29, signal interface II31, forward interface II33) conduit (including figure 1 and figure 2 The signal water pipe 2, reverse conduit 3, forward conduit 4) in the four parts constitute. The jet nozzle uses the principle of jet flow wall attachment to rotate the nozzle under the drive of the wall attachment force. Through the switching cooperation between the jet element and the reversing ...

The invention belongs to fluid control equipment, in particular to a jet-flow type spray head reversing control mechanism. The reversing control mechanism is taken as a key part, and mainly comprises a reverser, a limiting device, a receiving nozzle and guide pipes, wherein the reverser, the limiting device, the receiving nozzle and the guide pipes are matched with each other for completing forward and reverse stepping and switching of a spray head; the limiting device is used for controlling the position of a reversing valve core in the reverser to realize switching of a signal water flow direction; and gas supply and gas-water separation are performed through a bidirectional gap on a bidirectional gap cover plate and forward and reverse gas supply holes in forward and reverse guide pipes, so that running and bidirectional stepping of a jet-flow type spray are realized. The jet-flow type spray head reversing control mechanism has the advantages of high reliability, high switching stability, small impact on a rotating body, longer service life, capability of realizing forward and reverse stepping, more uniform water amount distribution of the jet-flow type spray head, more complete gas-liquid separation, and higher switching stability and reliability due to the insertion of a permanent magnet into a reversing valve.
