The work of the present invention uses process as follows:
nullWhen handle 5 rotates counterclockwise，Axle 7 is rotated by rotating cap 21，Rotary shaft 7 drives power transmission shaft 9 to rotate，The transverse axis 25 of power transmission shaft 9 sidepiece spigot surface 24 along guide cylinder 8 moves down，Disk 18 also moves down while rotating along disc seat 17，Thus disc seat 17 and shifting axle 10 are depressed，Shifting axle 10 can not rotate under the restriction of guide pad 15，Shifting axle 10 moves down and makes compression spring 11 compress，Sealing ring 12 moves down，Sealing ring 12 produces gap with the limbers 16 on faucet body 1，Current from intake tunnel 2 by this gap is flowed into exhalant canal 3，And handle 5 rotational angle is the biggest，Gap is the biggest，Current are the biggest，The first water hole 27 on disc seat 17 is the most corresponding with the second water hole about 28 on disk 18，So that current cannot be entered in water storage cavity 26 by through hole 13；When closing the faucet, handle 5 rotates clockwise, and location spring 34 promotes place kick 35 to be stuck on the V-groove 33 on guide cylinder 8 inwall thus navigates to closed position.
When handle 5 rotates clockwise return, power transmission shaft 9 rotates under the drive of rotary shaft 7, the transverse axis 25 on power transmission shaft 9 spigot surface 24 along guide cylinder 8 moves up, shifting axle 10 moves up under the effect of compression spring 11, and then make the sealing ring 12 of shifting axle 10 lower end block the limbers 16 on faucet body 1, make current to pass through, i.e. realize the closedown of faucet.
nullWhen faucet closed mode rotates clockwise handle 5，Its transmission principle rotates counterclockwise similar to handle 5，Except for the difference that power transmission shaft 9 rotates clockwise so that the first water hole 27 on disc seat 17 is corresponding with the second water hole about 28 on disk 18，Current pass through through hole 13、First water hole 27 and the second water hole 28 enter in water storage cavity 26，When handle 5 rotates counterclockwise return，Power transmission shaft 9 rotates under the drive of rotary shaft 7，The transverse axis 25 on power transmission shaft 9 spigot surface 24 along guide cylinder 8 moves up，Shifting axle 10 moves up under the effect of compression spring 11，Stagger with the second water hole about 28 on disk 18 in the first water hole 27 on disc seat 17，Water in water storage cavity 26 slowly can only be flowed out in time delay water hole 29 by damping hole 30 and time delay water hole 29，These current are flowed in exhalant canal 3 again，This results in shifting axle 10 and slowly moves up under the effect of compression spring 11，And then make sealing ring 12 time delay block the limbers 16 in faucet body 1，And then realize the time-delay closing of faucet.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and without departing from the spirit or essential characteristics of the present invention, it is possible to realize the present invention in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in the present invention.Should not be considered as limiting involved scope of the claims by any reference in claim.
