51,52,53 aim at three bleeders 221,222,223 place the valve support chamber 22 of inner core tube 2 successively, each

central bolt

51,52, be nested with back-moving spring 54 on 53 respectively, again three locating holes of pressing plate 55 are aimed at three central bolts and be fastened on the valve support chamber 22, this moment flange 513,523,533 are equipped with sealing ring 6 respectively is sealed and matched with each locating hole, and necking down 512,522, the 532nd, convexedly stretch in outside the pressing plate 55, each back-moving spring 54 lower end holds

central bolt

51,52,53 front cover 511,521,531 tops, and the upper end is to lean pressing plate 55 bottoms, be subjected to the effect of back-moving spring 54, each

central bolt

51,52,53 front covers 511,521,531 are nested with sealing ring 6 with each bleeder 221,222,223 states that seal up; Handoff block 56 is utilized its guide groove 561 to slide with the cooperating of guide rail 554 of pressing plate 55 and is placed on the pressing plate 55; Control taps 4 is assembled on the inner core tube 2, afterwards faucet body 1 is placed on outside the inner core tube 2, its rear portion and water inlet pipe are combined together, the front portion of faucet body 1 and discharging device 3 are combined together, and pressing plate 55 is cooperation slotted hole 11 places facing to faucet body 1, cover plate 13 be buckle solid on this slotted hole 11 so that slotted hole 11 is sealed, push button 57 bottom engagement tabs 572 are to utilize its claw 573 and the mating edge 564 of handoff block 56 to be connected together by linear through hole 131; The control taps is facing to mating holes 12 places, and press button 43 is to stretch to place this mating holes 12 and the central bolt 41 of control taps 4 to be combined together.

Cooperate Fig. 4,5, shown in 6, during tap combination normal condition, the piece 563 of lifting of handoff block 56 is that the flange that one of them central bolt in hanging support is in the state of lifting with central bolt, this sentences central bolt 51 and is normal condition (initial state), then central bolt 51 effect that is subjected to handoff block 56 to lift piece 563 is pulled up, back-moving spring 54 on this central bolt 51 is in the compress energy storage state, the bleeder 221 of inner core tube 2 valve support chamber 22 is opened, two bleeders 222 in addition, 223 are in the state of sealing, if button 43 by voltage-controlled taps 4, then current can flow into the inlet channel 21 of inner core tube 2, enter

valve support chamber

22 and 221 flow to the gondola water faucet water intake antrum of discharging device 3 through first diversion channel 224 from delivery port 227 from the bleeder, it is the bigger gondola water faucet water of water-outlet area that the tap of this moment goes out water state.

When the utility model switches enforcement, shown in Fig. 7,8, promoting push button 57 drive handoff block 56 moves to leading the place ahead, the piece 563 of lifting of handoff block 56 utilizes its oblique surface and stretches the necking down 522 that places second central bolt 52 and cooperate step surface 524 that second central bolt 52 lifted, so that bleeder 222 is opened, the protruding step surface 524 of the downward arc of tool this moment slips in the groove of lifting piece 563 end faces just, or in the arc concave surface, handoff block 56 can not produce slippage when making 222 water outlets of this bleeder, thereby guarantees that this goes out the stability of water state; Meanwhile, lift piece 563 and break away from and the cooperating of first central bolt 51, under the effect of back-moving spring 54, central bolt 51 is sealed bleeder 221; When central bolt 52 is pulled up, the bleeder 222 of valve support chamber 22 is in open mode, current then can bleeder 222 flow to the bubble water intake antrum of discharging device 3 through second diversion channel 225 from delivery port 228, and it is the bubble water that water outlet is comparatively concentrated that the tap of this moment goes out water state.

Shown in Fig. 9,10, continuing to promote push button 57 drive handoff block 56 moves to leading the place ahead, handoff block 56 is lifted the 3rd central bolt 53, second central bolt 52 resets, the bleeder 222 of valve support chamber 22 is in open mode, current then can bleeder 222 flow to the massage water intake antrum of discharging device 3 through the 3rd diversion channel 226 from delivery port 229, and the tap of this moment goes out the massage water that water state is the tool massage effect.

Certainly, above-mentioned change action can look-ahead operations be opened effluent switch 4 again, switches when also can push effluent switch 4.

To sum up, the utility model is by be provided with independently diversion channel 224 in the valve support chamber 22 of inner core tube 2,225,226, each diversion channel 224,225,226 water inlet 221,222,223 by the effect that is subjected to back-moving spring 54 the automatically reset central bolt 51 of tool, 52,53 involutions, and each

central bolt

51,52,53 are relied on external force push button 57 to drive that handoff block 56 are divided other pull-up and each water inlet 221 of opening valve support chamber 22 respectively, 222,223, current can pass through each diversion channel 224 respectively, 225,226 through each delivery port 227,228,229 enter respectively in each function water cavity of discharging device 3, realize the selection and the switching of leading function water with this, because handoff functionality is moving horizontally on the straight line, the user can push effluent switch 4 by the palm of the hand, the switching that moves forward and backward the realization function water of finger push push button 57 so makes the user convenient in use, laborsaving and meet ergonomics.
