Abstract

Disclosed is a time delay automatic-closing water-saving tap, which mainly comprises a water chamber, a pressing rod, a pressing handle, a water inlet, a water outlet, a pressing spring arranged in the water chamber, a piston, a piston passage hole and a through hole valve. The utility model has the advantages of simple structure, convenient use and good water saving effect. The water tap can be opened by only downward pressing a pressing cap. The water tap can be automatically closed after the preset delay time and also the delay time can be controlled by the user according to the requirements. The phenomenon of large quantity waste caused by the water tap is forgot to be closed can be effectively avoided. The utility model is in particular suitable for institutions, schools, stations, docks and other public places and also suitable for the use of families.

Description

Time delay self-closing water-saving tap

The utility model is a kind of water conserving tap, belongs to self-closing fluid infusion valve field.

Opening or closing of ordinary faucet all needs manual control, for public sanitary places such as office, school, station, harbours, often closes untimelyly because of water tap, and tap water is run off in a large number, causes very big waste.

The purpose of this utility model is in order to address the above problem, to design delayed self-close water conserving tap a kind of simple in structure, easy to use, that also can close automatically.

The utility model is by water cavity, depression bar, pressure handle, water intake, water outlet and the stage clip that is contained in the water cavity, piston, piston hole and through hole valve are formed, wherein, water intake and water outlet are positioned at the water cavity both sides, piston in the water cavity is connected with the depression bar that stretches out water cavity, pressure handle is contained in the depression bar top, between stage clip places at the bottom of piston and the water cavity, the length of piston side wall is greater than the diameter of intake-outlet, have a through hole on the piston, one-way cock is housed on the through hole, this one-way cock is made up of a narrow meshed rubber and tinsel and set screw, and narrow meshed rubber places on the through hole, tinsel be pressed in a side of rubber and by screw on piston.

Accompanying drawing is a structural representation of the present utility model.

Referring to accompanying drawing, for the ease of installing, the water cavity bottom separately is connected with internal and external threads with water cavity, during assembling, with screw 6 with tinsel 7 and band aperture rubber 8 be fixed on piston hole 9 above, then depression bar 3 and piston 5 are packed into water cavity 2 and make depression bar 3 stretch out water cavity from top is contained in stage clip 10 bottom of piston 5 again, tightens water cavity bottom 12 at last and load onto pressure cap 4 to get final product.During use, water intake 1 is connected by screw thread and intake pipe, pressure cap is pressed down, piston 5 is moved downward and leave water intake 1 and water outlet 11, water tap promptly is unlocked, water flows out from water outlet above piston at water intake, when pressing down, narrow meshed rubber 8 upwarps on the piston hole because of the effect of hydraulic pressure makes, the water of water cavity bottom flows into piston top rapidly through piston hole 9, so do not influence the opening speed of water tap, when pressure cap loses pressure, the elastic force of stage clip 10 moves upward piston, this moment, narrow meshed rubber 8 was close on the piston hole 9, the water on water cavity top can only enter the water cavity bottom through the aperture on the rubber 8, because the diameter of aperture is very little, current just slow, make piston 5 upward speed also slow, water tap is closed voluntarily when piston side wall blocks intake-outlet fully, and the hole diameter on the length of this section delay time and the rubber 8 is closing, and the big time-delay in aperture is short, the little time-delay in aperture is long, after fixed apertures, the distance that delay time and piston move downward is being closed, and pressure cap is long more by the big more delay time of distance down.

The utility model has the advantages that simple in structure, easy to use, water-saving result is good, only need click pressure cap can open tap, and behind predetermined delay time, tap gets final product autoshutdown, and delay time can be grasped as required voluntarily, can effectively avoid closing the phenomenon that tap causes a large amount of wastes because forgetting, be specially adapted to the public places such as office, school, station, harbour, also be fit to family's effect.

Claims (2)

1, a kind of in good time self closing water-saving tap comprises water cavity, depression bar, pressure handle, water intake, water outlet, it is characterized in that being equipped with in the water cavity stage clip, piston, piston hole and through hole valve, its mounting point and annexation are: water intake and water outlet are positioned at the water cavity both sides, piston in the water cavity is connected with the depression bar that stretches out water cavity, pressure handle is contained in the depression bar top, between stage clip places at the bottom of piston and the water cavity, the length of piston side wall is greater than the diameter of intake-outlet, have a through hole on the piston, one-way cock is housed on the through hole.

2, delayed self-close water conserving tap as claimed in claim 1 is characterized in that one-way cock is made up of narrow meshed rubber and tinsel and set screw, and narrow meshed rubber places on the through hole, tinsel be pressed in a side of rubber and by screw on piston.
