During assembling, modulating valve 3 is filled in the cone shape hole 41 of constant current valve seat 4, make the newel 32 of modulating valve 3 pass the center hole of supporting frame 42, then pressure release valve seat 5 is filled in constant current valve seat 4 from the waterexit end to the direction of feed-water end, its inner hole sleeve is connected on the newel 32 of modulating valve 3; Decompression valves 6 inserts its endoporus from the waterexit end of pressure release valve seat 5, and passes the support 33 of modulating valve 3; Pressure release spring 2 is filled in its central through bore from the feed-water end of modulating valve 3, then the direction of screw 1 from feed-water end to the waterexit end passed pressure release spring 2, be screwed in the endoporus of Decompression valves 6 valve rods; The column spring section of Regulation spring 7 is filled in it regulates chamber 43 and is screwed on the outer wall thread of pressure release valve seat 5 from the waterexit end of constant current valve seat 4; Filter core 8 is put into it from the waterexit end of constant current valve seat 4 and regulated chamber 43; Again constant current valve seat 4 is filled in its inner chamber from the feed-water end of shell 9, fill in from the waterexit end of shell 9 spraying 10 again, make and spray on the inner thread in adjusting chamber that an external thread rotary of water intake end outer wall is screwed in the constant current valve seat, the direction to feed-water end compresses filter core from the waterexit end to spray head, and filter core compresses Regulation spring again.

During work, open switch, water enters into the constant current shower, the water inlet end face of water impact modulating valve, due to the pressure-acting of Regulation spring 7, modulating valve 3 is in open mode, and current flow into from the gap between modulating valve and constant current valve seat regulates chamber 43, pass filter core 8 and enter and spray head, then eject from the spray orifice that sprays a waterexit end.

When the hydraulic pressure of the modulating valve 3 of flowing through larger, when being enough to overcome the prestressing force of Regulation spring 7, gap between modulating valve and constant current valve seat will be just little, the water yield that flows through leading constant current water outlet will reduce, as hydraulic pressure minimizing this moment, under the effect of Regulation spring, the gap between modulating valve and constant current valve seat can become again greatly, thereby plays the constant current effect of current stabilization flow control.The hydraulic pressure of modulating valve is large especially if flow through, the prestressing force that surpasses Regulation spring, at this moment, gap between modulating valve and constant current valve seat is blocked fully, powerful hydraulic pressure will promote Decompression valves 6 by the central through bore of modulating valve, Decompression valves overcomes the pressure of pressure release spring, and the space between Decompression valves and pressure release valve seat is opened, and current are just regulated the chamber from the central through bore inflow of modulating valve.So just can prevent from the cutout phenomenon occurring when hydraulic pressure is especially big, and guarantee suitable water-outlet quantity.

In actual use, the user can spray head in the position of the mixing chamber of constant current valve seat by adjusting according to the actual demand of self, controls max water yield.The direction that sprays a past feed-water end is twisted, and the feed-water end that sprays head is pressed Regulation spring to the direction of feed-water end, makes the prestressing force of Regulation spring strengthen, thereby strengthens water-outlet quantity.Otherwise will reduce water-outlet quantity.

The constant current shower can not produce harmful effect to current when hydraulic pressure is low, only have when hydraulic pressure is excessive, just plays a role, and like this, has both played the effect of constant current, does not affect again user's normal use.

Above-described embodiment is only interpretation purposes of the present utility model; and be not to be to restriction of the present utility model, those skilled in the art are in essential scope of the present utility model; make a variety of changes or substitute, also should belong to protection category of the present utility model.
