Abstract

The utility model discloses an automatically-closing type water-saving sanitary faucet which comprises a valve body, a valve element and a valve handle. The valve handle is connected with the valve element, and the valve element forms a one-way valve structure in the valve body. The valve handle is arranged on the lower end of the valve element, and the valve handle penetrates downwards through the valve body and is in clearance fit with the valve body. After the faucet is used, the faucet can automatically close, and moreover can automatically clean the valve handle, and maintains clear and sanitary of the valve handle without manual operation.

Description

The self-closing water-saving sanitary water tap

Technical field

The utility model relates to water tap, relates in particular a kind of self-closing water-saving sanitary water tap.

Background technique

At present, the water tap that a lot of public places use all is to be undertaken manually opened and close by valve handle, easy like this appear at use tap water after, owing to valve cuts out and not in placely makes the always situation of flowing water of water tap, thereby cause the waste of water resources.In addition, when this manually operated water tap uses in public places, because valve handle is easily caused cross pollution by different user's contacts, extremely unhygienic.Although and existing induction switch water tap can address the above problem, its cost is higher, is difficult to promote the use of.

Summary of the invention

The purpose of this utility model provides a kind of self-closing water-saving sanitary water tap, and after water tap used, without manually-operable, water tap got final product autoshutdown, and can clean valve handle voluntarily.

Self-closing water-saving sanitary water tap described in the utility model comprises valve body, spool and valve handle, and valve handle connects with spool, and spool is positioned at valve body and forms one-way valve structures, and described valve handle is positioned at the lower end of spool, and valve handle passes and the valve body Spielpassung in valve body downwards.

Described valve handle lower end is positioned near the valve body water outlet, so that the opening of water tap.

Described spool is the rounding stage body that upper end diameter is large, lower end diameter is little, it is positioned at the valve channel that valve interior wall is conical surface, and the conical surface of spool can be fitted with the valve interior wall conical surface, be provided with Compress Spring between the upper-end surface of spool and valve body, this Compress Spring gives the active force that spool fits spool conical surface and valve interior wall conical surface.

During use, only with hand upwards pushes valve handle, and valve handle band movable valve plug moves upward, and makes between spool and the valve interior wall gap to occur, and the tap water in the valve body flows out from this gap, flows out from the valve body water outlet again.Hand is unclamped, and under the Action of Gravity Field of hydraulic pressure, Compress Spring power and spool, valve handle, spool conical surface and valve interior wall conical surface fit again, and with the valve channel sealing, tap water stops to flow out from water tap spool again.

Self-closing water-saving sanitary water tap described in the utility model, because valve handle passes in valve body downwards, valve handle and valve body contacting point have the gap, when the pushing valve handle makes water flow out from water tap, having sub-fraction water flows out from the gap of valve handle and valve body contacting point, valve handle is washed, valve handle is kept hygienically clean.After water is complete, because spool can be about to valve channel sealing certainly under the Action of Gravity Field of hydraulic pressure, Compress Spring power and spool, valve handle, thereby without manually-operable, water tap can be realized autoshutdown, has avoided owing to water valve cuts out the waste that causes water resources not in place.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

In order further to explain the technical solution of the utility model, the utility model is elaborated below by coming by reference to the accompanying drawings.

As illustrated in figs. 1 and 2, this self-closing water-saving sanitary water tap comprises valve body 1, spool 2 and valve handle 3, the lower end that valve handle 3 is positioned at spool 2 connects with spool 2, and valve handle 3 passes and valve body 1 Spielpassung in valve body 1 downwards, and valve handle 3 lower ends are positioned near the water outlet 5 of valve body 1.

Described spool 2 is the rounding stage body that upper end diameter is large, lower end diameter is little, it is positioned at valve body 1 passage that valve body 1 inwall is conical surface, and the conical surface of spool 2 can be fitted with valve body 1 circular conical surface of inner wall, be provided with Compress Spring 4 between the upper-end surface of spool 2 and valve body 1, this Compress Spring gives the active force that spool 2 fits spool 2 conical surfaces and valve body 1 circular conical surface of inner wall.When valve handle 3 was not subject to the external force pushing, spool 2 was under the Action of Gravity Field of hydraulic pressure, Compress Spring 4 power and spool 2, valve handle 3, and spool 2 conical surfaces and valve body 1 circular conical surface of inner wall fit, and spool 2 is with valve body 1 channel enclosed, and tap water can not flow out from water tap.

Claims

1. self-closing water-saving sanitary water tap, comprise valve body (1), spool (2) and valve handle (3), valve handle connects with spool, and spool is positioned at valve body and forms one-way valve structures, it is characterized in that: described valve handle is positioned at the lower end of spool, and valve handle passes and the valve body Spielpassung in valve body downwards.

2. described self-closing water-saving sanitary water tap according to claim 1, it is characterized in that: described valve handle (3) lower end is positioned near the valve body water outlet (5).

3. described self-closing water-saving sanitary water tap according to claim 1 and 2, it is characterized in that: described spool (2) is the rounding stage body that upper end diameter is large, lower end diameter is little, it is positioned at the valve channel that valve body (1) inwall is conical surface, and the conical surface of spool can be fitted with the valve interior wall conical surface, be provided with Compress Spring (4) between the upper-end surface of spool and valve body, this Compress Spring gives the active force that spool fits spool conical surface and valve interior wall conical surface.
