Embodiment

The invention will be further described below in conjunction with accompanying drawing:

Fig. 1 is the first embodiment's of the present invention structural representation; Among the figure, comprise tap shell 16, water tap water inlet 5, faucet outlet 11, cut off on 17 in the water tap and have main water-saving valve water outlet 59, between piston shape master water-saving valve water outlet door 57 belows and the main water-saving valve water outlet 59 main water-saving valve water outlet rubber seal 60 is housed, piston shape master water-saving valve water outlet door 57 is loaded in the cylindrical water-saving valve housing 66 and can slides up and down, piston shape master water-saving valve water outlet door 57 inwalls have chromaffin body water valve water outlet 61 above the bottom, chromaffin body water valve water outlet rubber seal 62 is housed between chromaffin body water valve water outlet door 58 bottoms and the chromaffin body water valve water outlet 61, between chromaffin body water valve water outlet door 58 tops and cylindrical water-saving valve housing 66 inner tops stainless steel spring 19 is housed, piston shape master water-saving valve water outlet door 57 bottom master's water-saving valve water outlet rubber seal have for 60 times under the chromaffin body water valve water outlet and distribute the mouth of a river 63, contraction flow region 65 is a circular platform with water-saving valve push rod 64 connecting parts on the water-saving valve push rod, contraction flow region 65 inserts from piston shape master water-saving valve water outlet door 57 lower bottom part central openings and passes piston shape master water-saving valve water outlet door 57 on the water-saving valve push rod, contraction flow region 65 upper ends and chromaffin body water valve water outlet door 58 are for being threaded on the water-saving valve push rod, chromaffin body water valve water outlet 61 distributes in 63 bottoms, the mouth of a river under the chromaffin body water valve water outlet and leaves current between the contraction flow region 65 on the water-saving valve push rod and pass through the gap, on piston shape master water-saving valve water outlet door 57 lower bottom part central openings and the water-saving valve push rod between the contraction flow region 65 for being slidingly matched, contraction flow region 65 connecting part circular platforms and piston shape master water-saving valve water outlet door 57 lower bottom parts are provided with the switch gap of 61 of chromaffin body water valve water outlet door 58 and chromaffin body water valve water outlets on water-saving valve push rod 64 and the water-saving valve push rod, and tap shell is equipped with water-saving valve push rod axle sleeve 7 for 16 times.

For solving hydraulic pressure upper firmly problems of too of water-saving valve button 25 of pressing of finger when large, the present invention program has adopted main water-saving valve and chromaffin body valve structure to solve, wherein main water-saving valve water outlet 59 diameters are greater than chromaffin body water valve water outlet 61, current enter tap shell 16 through water tap water inlet 5, because making a concerted effort to pressing down chromaffin body water valve water outlet door 58 and piston shape master water-saving valve water outlet door 57 of stainless steel spring 19 pressure and hydraulic pressure, so chromaffin body water valve water outlet rubber seal 62, main water-saving valve water outlet rubber seal 60 downward press seals have closed chromaffin body water valve water outlet 61 and main water-saving valve water outlet 59, current are closed in cut off 17 tops in the water tap, faucet outlet 11 not there are flowing out, during use both hands are done to hold in both hands watery, upwards press water-saving valve button 25 through water-saving valve push rod 64 in the top with finger, contraction flow region 65 on the water-saving valve push rod, chromaffin body water valve water outlet door 58 is with stainless steel spring 19 compressions, because contraction flow region 65 connecting part circular platforms and piston shape master water-saving valve water outlet door 57 lower bottom parts are provided with the switch gap of 61 of chromaffin body water valve water outlet door 58 and chromaffin body water valve water outlets on water-saving valve push rod 64 and the water-saving valve push rod, so the chromaffin body water valve water outlet rubber seal 62 that chromaffin body water valve water outlet door 58 is attached thereto is at first upwards left chromaffin body water valve water outlet 61, at this moment the water in the cylindrical water-saving valve housing 66 distribute the mouth of a river 63 from chromaffin body water valve water outlet 61 first and cut off 17 bottoms in the water tap and flow out under chromaffin body water valve water outlet, distribute the mouth of a river 63 under the chromaffin body water valve water outlet and be opened on both sides, piston shape master water-saving valve water outlet door 57 bottom, owing to be provided with appropriate gap between piston shape master water-saving valve water outlet door 57 outer walls and cylindrical water-saving valve housing 66 inwalls, therefore there is the proper amount of water can be in the gap flows into cylindrical water-saving valve housing 66 inner chambers, but the water yield that this gap flows into is less than the water yield that discharges through chromaffin body water valve water outlet 61, therefore cylindrical water-saving valve housing 66 inner chamber hydraulic pressure are less than piston shape master water-saving valve water outlet door 57 hydraulic pressure of going to the bottom the time, so water-saving valve push rod 64, when the circular platform on the water-saving valve push rod between the contraction flow region 65 makes progress piston shape master water-saving valve water outlet door 57 bottom, top again, owing to do not had water to the downward pressure of piston shape master water-saving valve water outlet door 57, even the instantaneous negative pressure that can be of this pressure, therefore can like a cork piston shape master water-saving valve water outlet door 57 upwards be pushed up, main water-saving valve water outlet rubber seal 60 is left main water-saving valve water outlet 59, water flows out through faucet outlet 11 from main water-saving valve water outlet 59 and flows out, fill the sailor and refer to leave water-saving valve button 25, stainless steel spring 19 makes chromaffin body water valve water outlet 61 to pressing down, main water-saving valve water outlet 59 is successively closed, faucet outlet 11 is cut off the water supply, be water tap is easily controlled in available action of holding water in hands with finger opening and closing

Fig. 2 is the second embodiment's of the present invention structural representation; Among the figure, hold concurrently device on the self-locking plate end cap 67 of chromaffin body water valve water outlet door has by water-saving valve from lock slide 69, water-saving valve from the fixing water-saving valve self-locking device that consists of of sliding sleeve 68, lock-bit one-way circulation chute 33, elastic hook 32, water-saving valve self-lock rod U-groove bevel 36, stainless steel spring 19 of lock slide.
