Operation principle：

The connection of 5 flow of top spray with block：Water enters hydroecium 13 from water pipe 10, by turning knob 2.24, drives axle sleeve One 2.21 axle sleeves 2 2.22 and plectrum 2.23 rotate simultaneously；When the conduction hole 1 on plectrum 2.23 and the sector on water inlet 26 When 29 connection of opening, water initially enters inside spool 2；When plectrum 2.23 shelters from sector open 29, water is blocked in valve Inside core 2.Therefore, by turning knob 2.24 to realize the break-make water of control top spray 5.

4 flow of shower connection with block it is identical as the principle of above-mentioned top spray 5.

The pattern that top spray 5 is sprayed is adjusted：When water enters spool 2 from hydroecium 13 by water inlet 26 and conduction hole 1 Behind inside, by pressing button 2.35, transmission shaft 2.31 transfers the pressure on tailstock barrel 2.33, triangle on tailstock barrel 2.33 The inclined-plane of triangular bump 2 50 starts to contact on the inclined-plane and catch 2.34 of convex block 1, due to triangular bump 1 and only The clamping of turn trough 49 makes it that can not rotate so that triangular bump 2 50 mutually abuts on two inclined-planes and continues in tailstock barrel 2.33 Under effect, catch 2.34 starts to rotate because of the component that contact of incline plane generates；Conduction hole 2 46 on catch 2.34 turn to While drainage trough 1 is connected to, catch 2.34 blocks drainage trough 2 38；Release button 2.35 at this time, in the effect of spring 47 Lower rotary shaft and tailstock barrel 2.33 reset, and triangular bump 1 and triangular bump are detached from, and catch 2.34 no longer rotates.Water is from drawing Discharge orifice 2 46 enters in drainage trough 1, guides flow at the outlet 1 on shell 2.1 into air stream enter runner in drainage trough 1 After one 14, water is from runner 1 into incoming interface 1, in a half round runner 51 for eventually entering into tube body 3.

After pressing lower button 2.35 again, the conduction hole 2 46 on catch 2.34 is turned to be connected to together with drainage trough 2 38 When catch 2.34 drainage trough 1 is blocked；Water enters from conduction hole 2 46 in drainage trough 2 38, and water is guided in drainage trough 2 38 For stream into after air stream enter runner 2 15 from the outlet 2 31 on shell 2.1, water eventually enters into pipe from runner 2 15 into incoming interface 2 6.2 In another half round runner 51 of body 3.To realize the switching of 5 spray pattern of top spray.

The pattern Principles of Regulation that shower 4 sprays are identical as the principle that above-mentioned top spray 5 is sprayed.

The Fast Installation of top spray 5 and tube body 3：After being caught in sealing ring 7 79 on the annular groove 7 78 in water flowing portion 9.1, it will push up Incoming end 1 and incoming end 2 84.2 in spray interface 84 are docked with the entrance in water flowing portion 9.1 1 and entrance 2 57 respectively On, then fixed part 9.2 screwed in into top spray interface 84, inner ring 61 and outer shroud 60 is made to push against, to realize to tube body 3 and top spray 5 Fast Installation.

The Fast Installation principle of shower 4 and tube body 3 is identical as the principle of above-mentioned top spray 5 and tube body 3.

The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to Above-described embodiment, technical solution belonging to the idea of the present invention belong to the scope of protection of the utility model.It should refer to Go out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
