Abstract

The utility model provides an automatic water saving valve, which is characterized in that a switch handgrip forward extends and is downward bent to the lower end of a water outlet of a valve body; a spring is arranged in a handgrip cover of the switch; the upper end of the spring is connected with the handgrip cover of the switch, and the lower end is connected with a valve seat. When the hands are washed, the hand lies against and pushes the switch handgrip to the right, and then the switch handgrip overcomes the spring force to drive the valve rod to swing to open a valve core, and then running water flows out. The hands leave the switch handgrip after wetted, and then the switch handgrip returns to the original position under the action of the spring force, and furthermore, the valve rod is driven to make the valve core closed and the running water does not flow any longer lavishly; at this time, the soaps can be smeared; when the hands are irrigated, the hands lie against and push the switch handgrip to the right to open the water valve to irrigate the hands; after the hands are irrigated and the hands leave the switch handgrip, the switch handgrip quickly returns to the original position under the action of the spring force, and then the water valve automatically close, thereby, the goal of water saving is realized.

Description

Automatic water-saving valve

Technical field

The utility model relates to a kind of water valve from the beginning, specifically to the improvement of existing tap water valve arrangement.

Background technique

Existing water valve from the beginning has some kinds of forms.Divide from opening ways, modal a kind of be the maximum unlatching scope of valve rod for changeing 1/4 circle, generally be to change 1/4 figure counterclockwise.Above-mentioned water valve exists following deficiency: 1, when washing one's hands, open water valve after, tap water trickles out, behind the wet hand, need smear soap, but in this following period of time, as closing water supply valve, also need open again, just bother very much, as be not related to water supply valve, tap water continues trickling, cause the tap water waste, the main cause of above-mentioned defective is that water valve does not have due to the automatic closing function from the beginning.2, after water valve was opened to certain position, flow was certain, if will regulate the flow size at any time, needed rotation valve rod back and forth, not only bothered but also waste tap water.3, existing water valve from the beginning in use, particularly factory, hotel, school, building site, etc. the public place, the time regular meeting water valve occurs and close not in placely, and the trickling phenomenon that occurs more has the wasting phenomena of the perennial draingage of not closing and occurring.

How overcoming above-mentioned deficiency, then is the design problem that the utility model faced.

Summary of the invention

The utility model provides a kind of automatic water-saving valve, and it does not have the existing problem of automatic closing function to solve existing water valve from the beginning.

In order to reach the purpose that solves the problems of the technologies described above, the technical solution of the utility model is, a kind of automatic water-saving valve, it comprises valve body, valve rod and switch handle, it is characterized in that the switch handle extends forward and is bent downwardly water outlet lower end to valve body, in the switch grip spring is housed, the spring upper end is connected switch putting, and the lower end is connected on the valve rod base.

In the utility model, also have following technical characteristics: spring suit valve rod, the spring upper end is inserted in the hole of switch grip, and the lower end is inserted in the hole of valve rod base.

In the utility model, also has following technical characteristics: switch handle likeness in form numeral 7.

The utility model is compared with existing technology and is had the following advantages and good effect: 1, the utility model is the improvement of carrying out on the water valve basis of former unlatching 1/4 circle, with original switch extending forward and being bent downwardly lower end correct position to water outlet, the recovery spring is housed in the switch grip, when washing one's hands, hand extends water outlet, leans against switch with hand and pushes away to the right last, and switch drives the valve rod rotation overcoming spring force, open spool, tap water flows out, and behind the wet hand, hand leaves the switch handle, switch is setting back under the effect of spring force, and then drive valve rod spool is closed, the no longer empty stream of tap water, at this moment, can smear soap, during towards hand, relying on the switch handle with hand again, pushing away to the right, open water valve towards hand, when hand finishes, when hand leave switch after, switch is return rapidly under the effect of spring force, water valve cuts out automatically, thereby has realized the purpose of water saving.2, the unlatching of water valve is to rely on hand push, and water yield size adjustment is easy and convenient, again using water wisely.3, with using, close automatically when not using, avoided the generation of empty flowing water phenomenon with opening.4, the utility model can be in the toilet of public places such as factory, school, hotel, hotel, building site, airport, station, and uses in the family.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in detail.

Fig. 1 is a plan view of the present utility model;

Fig. 2 is a sectional view of the present utility model.

1, automatic water-saving valve; 2, valve body; 2-1, water outlet; 3, switch handle; 3-1, switch grip; 3-2, switch handle; 4, valve rod; 5, valve rod base; 6, spring.

Embodiment

Referring to Fig. 1 and Fig. 2, automatic water-saving valve of the present utility model is used mark 1 chief representative.The utility model is that the water valve that maximum unlatching scope 1/4 is enclosed is improved.On its basis, switch improved 3 handle 3-2 being designed to likeness in form numeral 7, as " big trunk ", promptly switch handle 3-2 extends forward and is bent downwardly to the appropriate location of the water outlet 2-1 lower end of valve body 2, so that with hand buck switch handle 3-2 to the right.In switch grip 3-1, spring 6 is housed, spring 6 suit valve rods 4, spring 6 upper ends are inserted in the hole of switch grip 3-1, and the lower end is inserted in the hole of valve rod base 5.

When buck switch handle 3-2 to the right, switch grip 3-1 drives valve rod 4 rotations because of being connected with valve rod 4, and spool is opened, and tap water flows out.Under this state, switch grip 3-1 is because of being connected with spring 6, and makes spring 6 distortion, spring force make switch being in the return state.When hand leaves switch handle 3-2, under the restoring force effect of spring 6, make switch 3 returns, thereby valve rod 4 returns, spool is closed, thereby has realized that hand leaves the purpose of water valve self-closing link water.

Certainly, also can select as required switch handle 3-2 is left left, promptly clockwise direction changes 90 °, 1/4 circle, but the water valve internal structure needs to change slightly.

Above-mentioned explanation is not to be to restriction of the present utility model, and in design scope of the present utility model, variations such as the interpolation of being carried out, replacement, remodeling also should belong to protection domain of the present utility model.

Claims
