Description

A kind of timing self-closing faucet

The utility model relates to a kind of water tap, exactly is a kind of timing self-closing faucet.

At present, " running water " phenomenon and generation " flooding " in the family take place (owing to forget that closing water tap makes tap water from overflowing in order to prevent in public water place in people, cause indoor being flooded) phenomenon, so that the purpose that reaches using water wisely and avoid so cause people's property loss, research and design goes out a kind of water tap that can close automatically in the certain hour after unlatching, this technology becomes invention by inventor Li Jia, its application number is 94228369, the authorization notification number is 2215049, the applying date is on April 18th, 94, name is called " regularly auto cut-off water saving valve ", this water tap mainly is by valve body, valve gap, spool, valve rod, pressure spring, timer, output gear is formed, spool is positioned at the valve body chamber, pack in the valve body in the valve rod lower end, pressure spring and gland are packed in turn from the valve rod upper end, and with valve gap by scyewed joint on valve body, make between valve rod and the valve gap to be slidingly matched, the top of this valve rod is exposed and is shaped on the bar shaped tooth on the bar section; Timer is fixedly connected at the upper lateral part of valve body, its output axle head fixed installation output gear, and this output gear is meshed with bar shaped tooth on the above-mentioned valve rod; When valve rod moves under external force, water tap is in opening state, and after external force was withdrawn from, valve rod automatic slowly under the elastic resistance effect of spring pressure and the release of timer inner spring moved down, end up to closing water tap, thereby reach the purpose that timing automatic is closed water tap.The shortcoming of this water tap is: the structure more complicated, manufacture cost is higher.

The purpose of this utility model is for people provide a kind of simple in structure, the timing self-closing faucet of low cost of manufacture.

The purpose of this utility model is achieved in that it comprises valve body, valve gap, spool, valve rod, timer, is characterized in: the same scyewed joint of valve rod and valve gap, and both form sealing; The axle shape guide rod that on described valve body, is fixedly connected, this guide rod axis is parallel with described valve rod axis; Described timer output shaft is fixedly connected with described valve rod upper end, both are coaxial; Be shaped on a through hole on the shell of this timer, this through hole is equipped mutually with described guide rod, and both are slidingly matched.

After the utility model is realized, all can adopt the ordinary faucet prior art owing to constitute its valve body, valve gap, spool, valve rod also only needs transformation is slightly done in ordinary faucet valve rod upper end portion, make it to realize and the timer output shaft between be fixedly connected and get final product, it is compared with existing regularly self-closing faucet, has not only omitted parts such as output gear, pressure spring, and make easily, thereby have simple in structure, low cost of manufacture, advantage such as easy to use.

Below in conjunction with accompanying drawing embodiment of the present utility model is done explanation in further detail.

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

As seen from the figure, the utility model is made up of valve body 11, valve gap 5, the spool that is positioned at valve body, valve rod 3, timer 1, guide rod 6, dunnage 8, sealing gasket 7, joining shaft 4 and packing ring 9 nuts 10, and wherein valve body 11, spool, valve gap 5, sealing gasket 7 all adopt the prior art of ordinary faucet to make; Valve rod 3 is to form with the transformation of the way of ordinary faucet valve rod, promptly makes an axial vexed hole and a radial direction through hole in the lower end of ordinary faucet valve rod, and this axial aperture, vexed hole and the timer output shaft 2 lower end diameters of axle match both transition fit; A radial direction through hole is made in timer output shaft lower end.This through hole is identical with the radial direction through hole aperture of above-mentioned valve rod upper end, the diameter of axle of this aperture and joining shaft 4 matches, both transition fit, guide rod 6, joining shaft 4 are all made with the metallic material map interlinking, wherein between the connecting hole on the cylindrical of guide rod 6 and the timer housing movingly, dunnage 8 usefulness sheet metals (thickness 1-1.5mm) map interlinking is made, and nut 10, packing ring 9 are the outsourcing standard piece; Timer forms with the 220V.16A type timer transformation that Cixi City Si Jia electrical apparatus factory produces, and transforms part and only is output shaft lengthening with timer, its lower shell body from the timer is stretched out, and its lower end is transformed into schematic structure; Demifacet is made in the cam upper-end surface at the wheeled tribute core of timer convex locking framework center; The bigger turn-knob 12 of diameter changes the outfit on the output shaft.

The output shaft 2 of above-mentioned timer also can be made one with the valve rod 3 of water tap, omits joining shaft 4 simultaneously.

Above-mentioned guide rod 6 also can directly cast out from valve body 11, omits dunnage 8, sealing gasket 7 and packing ring 9, nut 10 simultaneously.

After above-mentioned each part is got all the ready, get final product by the figure assembling.

In use, along being rotated counterclockwise turn-knob 12, water tap is opened; When the user need close water tap immediately, can be rotated in a clockwise direction turn-knob 12 to water tap and close apolipsis; When the user needs regularly water, can in the counterclockwise direction turn-knob be rotated on the position of required water time and get final product, afterwards, valve rod 3 is under the elastic force effect that the timer inner spring discharges, automatically be rotated in a clockwise direction, till closing water tap, thereby realize the task that it is regularly self-closing; When people need long-time water when (promptly surpassing the time range that timer limits), turn-knob 12 can be rotated in the counterclockwise direction locked position (timer itself has cammingly movement locking framework), can achieve the goal, when closing water tap, can be rotated in a clockwise direction turn-knob 12, till water tap is closed.

Claims (1)

1, a kind of timing self-closing faucet, it comprises: valve body, valve gap, spool, valve rod, timer is characterized in that: scyewed joint between valve rod and the valve gap, both form sealing; The axle shape guide rod that on described valve body, is fixedly connected, this guide rod axis is parallel with described valve rod axis; Described timer output shaft and described valve rod upper end are fixedly connected, and both are coaxial; Be shaped on a through hole on the shell of this timer, this through hole is equipped mutually with described guide rod, and both are slidingly matched.
