Description

Foot-valve for water saving

The present invention relates to a water-saving foot valve, and more particularly, to a water-saving foot valve for ensuring smooth operation and minimizing failure.

Recently, as part of efforts to improve water shortages all over the world, various water-saving foot valves have been devised to reduce the waste of water. In particular, the present inventors also referred to the "water-saving foot to prevent the waste of drinking water sources supplied to homes." "Valve" was previously filed as Utility Model Registration Application No. 20-2003-0014505.

The invention described above is inserted into a valve seat having a ceramic cartridge-type valve in a housing in which a valve exposure hole and a valve support plate are formed, and screwed into a valve fixing cap having a valve stopper and an annular locking jaw. The installed channel forming device is coupled to the elevating rod by a hinge so that the elevating rod is raised and lowered by the shaft, the elevating rod is coupled to the arc pulley so as to be rotatable by the shaft, and the arc pulley is rotatable by the hinge shaft. And it is coupled by the shaft to the elevating platform of the operating member coupled to the housing so that it can be restored in place by the spring, One side end of the operating member is coupled to the footrest by the spring shaft and the spring to rotate the elastic Configured to have an annular locking jaw in the valve fixing cap, and the locking jaw The end of the hanger formed in the middle of the operating member, that is, having a structure to hold the locking projection is fixed, if you want to stop using, first step on the front part of the foot slightly to remove the locking projection from the locking jaw and then step on the foot pedal firmly However, users who have not read the precautions carefully are forced to step on the footsteps unconditionally, and the operation is not smooth, and even the hanger or operating member is bent, which causes frequent A / S. It has a disadvantage.

The present invention has the disadvantage of the conventional water-saving foot valve, that is, the disadvantage that occurs when stepping on the footrest without removing the hanger first because of the structure of the hanger end of the operation member, that is, the locking projection is fixed to the locking jaw of the valve fixing cap In order to solve these problems, a fixed member that can be reciprocated by the pressure of the scaffold and the spring force of the spring is formed in the middle of the operating member, but the corrugated protrusion and the inclined surface are formed on the upper end of the fixing member so that the inclined surface is the It is to provide a water-saving foot valve is configured so that the corrugated projection is fixed to the catching jaw of the body incision by the operation, which is configured to open the channel.

The configuration of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view for showing the configuration of the present invention, the foot valve 1 of the present invention, the water inlet 201 and the water outlet 202 is formed in the front in the horizontal state and slide up and down, respectively. A well-known ceramic cartridge type valve 200 having a channel forming tool 203 for forming a water passage, and a valve seat having a valve 301 and 302 formed therein and having a thread 301 and 302 formed therein. 300, a housing 100 having a valve exposure hole 110 and a valve support plate 120 for mounting the valve seat, a valve fixing hole 310 for fixing a valve seat mounted on the housing, And, the valve fixing cap 320 is screwed to the rear inner side of the valve seat, and the lifting rod 210 is coupled to the hinge 206 to the channel forming port of the valve and coupled to the elevating by the shaft 205 ) And rotatable by the shaft 220 on the elevating rod It is equipped with an arc-shaped tow 400 and a lifting platform 520 for lifting the arc-type towing, but the hinge shaft 511 is penetrated to the end of the lifting and lowering, the spring 550 Rotating and elasticity by the actuation member 500 and the spring 810 to the end of the foot support 570 of the actuation member and the operating member 500 coupled to the housing to be restored in place by On the upper side of the fixing member 600 and the fixing member 600 which is coupled to be inserted into the reciprocating force by the elastic force of the spring 621 in the middle portion of the operating member 500, the coupling member 600, Waveform protrusion 640 in the front, the inclined surface 630 is formed in the rear, but when the inclined surface 630 is pushed forward by the footrest 800, the wave projection is the locking step 171 of the body incision 170 It is fixed by hanging on, and slightly stepping on the foot of the body incision 170 The waveform protrusion 640, which is fixed to the upper end, is configured to be released by being pushed back by the spring 621 on which the repulsive force acting to push each other back.

In this case, the operation of the fixing member 600 will be described in more detail. If only the front portion of the foot plate is pressed in a completely stepped state, the fixing member 600 is advanced by the inclined surface. Of the protrusions are fixed to the engaging jaw 171 of the incision 170 so that the operation member 500 is not rotated about the hinge shaft 511 even if the elasticity of the restoring spring 550 is applied. As a result, the water channel of the valve remains open.

In this case, a long hole 610 is punched in the middle of the fixing member 600, and the long hole 610 is reciprocated by a pin 580 fitted into a pin hole 581 of the operating member 500. Are combined. At this time, the lower end of the fixing member 600 is supported by the support plate 590 formed on the lower end of the operating member 500.

In addition, when releasing the fixing of the fixed member 600, as shown in FIG. 7, if you step on the footrest 800 only slightly, the fixing member 600 is pushed back by the spring 621 on which the repulsive force is applied. As a result, the corrugated protrusion 640 is separated from the latching jaw 171 of the cutout 170, so that the elasticity of the restoring spring 550 acts on the operating member 500. As the center rotates, the valve channel remains blocked.

At this time, the spring 621 is fitted to the projection 620 formed in front of the fixing member 600, one side is fixed to the spring hanger (540). The spring may be formed at the rear of the fixing member, but in this case, a spring acting on the attraction force should be used.

As described above, the present invention uses a fixing member having a corrugated protrusion and an inclined surface that does not bend or be damaged instead of a hook or a locking member that is easily bent, unlike a conventional foot valve. It is a very useful invention that can provide a foot valve that can be minimized to reduce after-sales service, smooth operation, and very simple structure.
