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 to save the source of drinking water supplied to the home by waterworks.

At present, many efforts are being made in each country to reduce the waste of water around the world, especially in Korea, which is a country with insufficient water, various studies are being conducted to save water.

In particular, for the waste of drinking water to be supplied to the home, the national level emphasizes the saving of water, and for this purpose, the water-saving device of the faucet with a fixing member has been filed as a patent application 2001-0016484.

However, the above patent application is provided with a valve case having a predetermined shape as well as a coupling means at the top to be fixed to one side of the lower surface of the sink, and a water inlet provided in the inside of the valve case and entering one side of the valve case. And a valve body having a predetermined channel formed therein, a dome-shaped packing of rubber material inserted into the valve body to open and close the channel, and pressing one side of the dome-shaped packing to one side of the valve body while being fastened to the valve body. A packing shaft housing for sealing the inside of the dome-shaped packing, an o-ring is installed at a predetermined position, a packing shaft whose tip is inserted through the dome-type packing and the packing shaft housing, and flows in an axial direction; A packing shaft extension member for extending a shaft, and a packing shaft extending under the packing shaft extension member. An elastic member for urging an extension member with a predetermined elastic force, a housing stopper supporting the elastic member and coupled to the packing shaft housing, and hinged to one side of the packing shaft by penetrating one side of the housing stopper. A connecting rod for smoothly inducing axial flow, one side of which is bent and the bending portion is hinged to a predetermined position, one end of which is a valve operating member hinged to one end of the connecting rod, and one end of the valve operating member Hinged and coupled to form a plurality of bent grooves in a predetermined position, the fixing member for rotating one end of the valve operating member to the hinge by the interference on one side of the foot seating member, and the locking groove formed on one side when the fixing member is rotated It is provided to be seated and the locking projection for supporting the fixing member, and the locking groove of the fixing member is the locking projection The foot is provided with an elastic member provided at a predetermined position of the fixing member and the valve operation member, and provided at one end of the valve operation member to receive the predetermined pressure to rotate the valve operation member so that the fixing member automatically returns to its original position. It consists of a seating member, which has the following disadvantages.

First, the valve of the water saving device requires a significant separation distance between the valve case and the sink because the channel is formed at right angles, and the hydraulic pressure acts at right angles to twist the shaft of the packing shaft. As a gap is generated, many A / Ss are generated due to leakage.

Secondly, since the valve of the water saving device has a structure in which the foot plate is restored by a spring built in the packing shaft housing, it is inconvenient to replace when the spring breaks down, and the packing shaft which drives the foot plate flows in the axial direction so that the packing Since the hydraulic pressure acts on the shaft, the restoring of the scaffold is not performed smoothly by the action of the hydraulic pressure.

Third, the scaffold of the water saving device has a structure in which the packing shaft is pulled horizontally, ie, in the axial direction, by a hinge shaft formed under the valve case. Thus, the forward and backward distances of the packing shaft can be very short compared to the rotation angle of the scaffold. Since there is only a well-known valve of a ceramic cartridge type (a valve made of a ceramic material slides vertically and shuts off a water inlet by blocking a water inlet) has a disadvantage in that it cannot be used structurally.

Fourth, the fixing member of the water-saving device has a disadvantage in that to form a locking projection formed separately on one side of the valve case. In addition, the fixing member has a structure that blocks the advancement of the valve operation member to move forward by being seated in the locking projection recessed in one side of the holding member, the locking groove has a narrow contact surface with the locking projection to be seated It is not easy, and will have a disadvantage that can not be used by wear in a long time use.

The present invention was devised to solve the drawbacks of the conventional water-saving foot valve. To this end, a ceramic cartridge type valve is used to completely block leakage, but a structure capable of lifting a lifting rod for operation of the valve is provided. It consists of an arc-shaped tow and the operating member.

Another object of the present invention consists of a locking member for easy and robust locking of the operating member.

Another object of the present invention consists of a foot valve fixing member for firmly and conveniently fixing the foot valve to the bottom of the sink.

Referring to the configuration of the subject innovation in detail as follows.

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 are formed in the front in a 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 tool 310 for fixing a valve seat mounted on the housing, The valve fixing cap 320 is screwed into the rear inner side of the valve seat and has an annular locking jaw 321, and the hinge 206 is coupled to the channel forming port of the valve and is lifted by the shaft 205. Lifting rod 210 coupled to the lowering and the lifting rod Arc-shaped tow 400 is rotatably coupled by the shaft 220 and the lifting platform 520 for lifting the arc-shaped tow, but the hinge shaft 511 is penetrated to the end of the lifting table An actuating member 500 coupled to the housing to be rotatable and restorable in place by a spring 550, and a scaffold shaft 900 and a spring 810 at the end of the actuating support 570 of the actuating member. It consists of a footrest 800 that is coupled to the rotatable and elastic action by.

At this time, shaft coupling holes 410 and 420 are perforated at both ends of the arc-shaped retractor 400, and the upper portion is lifted up and down by the shafts 430 and 220, and the lower portion is lifted up and down. Combined to be rotatable. In the present invention, all the axes are preferably fixed by pins or wedges.

The side shape of the operating member 500 is " At this time, the hinge shaft coupling hole 510 is perforated at the upper bending point of the operating member, and the hinge shaft 511 penetrates through the hinge shaft coupling hole to allow the housing 100 to pass through the housing 100. It is coupled by a pin to the coupling hole 150. Spring hanger 540 is formed on both sides of the lower bending point of the operating member, one end of the spring 550 is connected to the spring hanger and the The other end is connected to a spring hook rod 700 coupled to the housing 100 in a state adjacent to the hinge shaft 511.

Therefore, the spring 550 is to act to always lift the operating member 500, which is in a state of lifting the lifting rod 210 up, so the user presses the footrest support 570 of the operating member Previously, the channel 204 of the valve 200 is always in a closed state.

At this time, it will be preferable to form a footrest 800 on the footrest support so that the user can easily step on the footrest support. In addition, the scaffold 800 is rotatable and elastically coupled by the scaffold shaft 900 and the spring 810, which is a configuration necessary for the operation of the locking member 600.

The locking member 600 is necessary to open the channel 204 of the valve according to the user's needs, and for this purpose, an operation member, in particular, a scaffold support 570, which is always lifted up by the elasticity of the spring 550. Block the rise of the configuration of the locking member for blocking the rise of the scaffold support is as follows.

The side shape of the locking member 600 is " It has a shape such as ", the axial coupling hole 610 is drilled in the upper end, the axial coupling hole is rotatably coupled to the shaft 430 is formed at the end of the operation member 500.

In addition, a hook 620 is protruded from the middle of the locking member, and a hook protrusion 621 is formed at the end of the hook. The locking protrusion has a structure that is fixed to the locking projection 321 formed in an annular shape inside the valve fixing cap 320.

A restoring spring 640 is formed at the rear of the hanger, and the restoring spring is coupled by being caught by a restoring spring hook hole 560 drilled in the middle of the operating member.

Therefore, when the locking protrusion 621 is fixed to the locking jaw 321, the middle of the locking member is pulled forward by the elasticity of the restoring spring, so that the locking member is rotated about the hinge shaft 511. As it becomes impossible, the channel of the valve will remain open.

The lower end of the locking member is formed with a presser bar 630 that is bent and protrudes upward, and the presser bar is positioned so as to be close to the bottom surface of the footrest 800 so that the user completely steps on the footrest 800. If you step back on the foot of the footrest in the foot bar is lowered while rotating the locking member about the axis 430, so the hanger is in the state of moving forward.

Therefore, the locking projection formed at the end of the hanger is caught by the locking jaw of the valve fixing cap, so that even if the user removes the foot from the footrest, the operating member cannot be restored to its original position and cannot but remain intact.

At this time, in order to release the lock state, it is possible to simply step on the back of the scaffold once again. At this time, when the back of the scaffold is pressed, the locking protrusion 621 is separated from the locking jaw 321 and at the same time restores the spring. Since the elasticity of the 640 is reduced, the elasticity of the spring 550 that acted on the actuating member acts on the actuating member to restore the actuating member to its original position and close the valve.

Therefore, the degree of elasticity of the restoring spring 640 and the spring 550 in the present invention should be properly adjusted.

In addition, the present invention may form a foot valve fixing member 1000 for fixing the present invention foot valve 1 to the bottom of the sink (A) as shown in Figure 8 on the upper portion of the housing 100, The configuration of the foot valve fixing member 1000 is as follows.

That is, a cover 130 having a plurality of through holes 131 spaced at regular intervals and coupled to the upper end of the housing, and a substrate having a fitting protrusion 1120 and a screw thread 1110 fitted into the through holes. 1100, the lifting hole 1200 having a handle 1210 screwed to the screw thread 1110, and the fixing plate 1300 having a projection 1310 formed on the upper end of the lifting hole.

As such, the present invention has a structure in which a water inlet and an outlet are formed in a horizontal state in front of each other and slide upwards and downwards to form a channel so that a ceramic cartridge-type valve can be used with little fear of leakage. The biggest disadvantage is that it can completely solve the leak, which can significantly reduce the after-sales service.

In addition, the present invention is not a structure in which the operating member is restored by a spring built into the valve, but a structure formed directly on the operating member and the housing, so it is easy to replace even in the event of a spring breakdown. As the channel forming port moves in a vertical direction rather than an axial direction, the channel is formed, which is irrelevant to the action of hydraulic pressure, and thus there is no fear of failure. The restoring of the scaffold also has a smooth effect.

In addition, the foot valve of the present invention is coupled to the rotatable by the shaft formed on the end of the operation member, and in the middle of the locking member is provided with a hanger having a locking projection is formed so that the locking projection is inside the valve fixing cap. It is possible to maintain the open state of the valve by being caught by the locking jaw formed in an annular shape and blocking the restoration of the locking member by the elasticity of the restoring spring. Therefore, unlike the conventional foot valve, a separate locking protrusion needs to be formed in the housing. No, it is a very useful design that does not have to worry about wear of the concave grooves due to long time use.
