As shown in the drawings, the present invention is provided with a faucet (2) on the water tank (3) of the upper portion of the sink (1) and the valve case 100 is installed on one side of the lower surface of the sink (1) By pressing the provided foot seating member 90 by the user's foot to allow water to be discharged from the faucet (2).

Four female screws 300 are provided at predetermined positions inside the valve case 100, and the female screws 300 are coupled to the female screws 300 to rotate and move up and down.

When the male screw is rotated to rise, a fixing pin 210 is provided at an upper portion of the sink so as to be fixed to the bottom of the sink bottom panel.

In addition, the lower end of the fixing pin 210 is provided with an annular protrusion 220 protruding the outer peripheral surface by a predetermined length to facilitate the rotation of the male screw 200 by hand.

On the other hand, the valve body 10 is provided with a water inlet 11 on one side so that water is supplied from the outside and formed in a predetermined channel therein is fixed to the upper rear wall of the sink 1.

In the valve body 10, a packing shaft 40 having a plurality of O-rings 42 is inserted and installed at a predetermined position, and a dome-shaped packing 20 is inserted into an upper portion of the packing shaft 40, and the packing shaft ( 40 is provided with a packing shaft housing 30 for screwing in one end of the valve body (10).

The packing shaft housing 30 has a housing stopper 60 having a predetermined friction groove 31 formed therein in an axial direction at one end thereof, and a predetermined air in the friction groove is externally connected to one side of the friction groove 31. An air outlet 32 for discharging is formed.

On the other hand, the domed packing 20 is made of a rubber material and integral with one end thereof is protruded so that the packing shaft housing 30 and the valve body 10 are screwed together when the screw is coupled to seal the inside of the valve body 10 and the packing The O-ring 42 provided on the outer circumferential surface of the shaft 40 seals the inside of the domed packing 20 to prevent water from flowing into the water saving device, and oil in the domed packing 20 is leaked to the outside and mixed with water. To prevent them.

The packing shaft 40 is provided through the packing shaft housing 30 and the packing shaft extension member 41 is screwed to one end of the packing shaft 40 so that the packing shaft extension member 41 is connected to the housing. Inserted into the friction groove 31 of the stopper 60 is provided.

In addition, the packing shaft extension member 41 is provided with a friction member 42 made of rubber material on the outer circumferential surface of the packing shaft extension member 41 in contact with the inner circumferential surface of the friction groove 31 of the housing stopper 60. ), The predetermined friction force is generated.

Meanwhile, an elastic member 50 is provided at one side of the packing shaft extension member 41 to press the packing shaft extension member 41 in the axial direction with a predetermined elastic force.

The housing stopper 60 is screwed to the packing shaft housing 30 to support the elastic member 50, and the packing shaft extension member 41 supports the steel wire 71 passing through the housing stopper 60. Coupled to one side of the packing shaft 40 and one end of the steel wire 71 is provided with a connecting rod 70 by a hinge, one end of the connecting rod 70 of the "b" type valve operating member 80 One end is joined by a hinge.

The valve actuating member 80 is configured to be bent at one side thereof, and the bent part is hinged and fixed at a predetermined position, and once the other end of the valve actuating member 80 is pressed, one end of the connection rod 70 is formed around the hinge of the bent portion. ) Is hinged and rotated.

One end of the valve operation member 80 is provided with a foot seating member 90 to press the user's foot.

According to the present invention configured as described above, the user presses the foot seating member to rotate the valve operating member, moves the packing shaft in the axial direction, opens the channel, and then uses the water supplied.

When using a predetermined amount of water and cutting water, when the user removes the pressure applied to the foot seating member, the packing shaft is advanced by the elastic member which is provided in the housing stopper and presses the packing shaft extension member in the axial direction. .

At this time, the friction member, which is a rubber material provided on one side outer circumferential surface of the packing shaft extension member, generates friction force with the inner circumferential surface of the friction groove formed at one end of the housing stopper and compresses a predetermined amount of air in the friction groove. The packing shaft is advanced while discharging a small amount of compressed air through an air outlet having a predetermined diameter formed at one side.

The packing shaft is not elastically advanced by the elastic member, but is gradually advanced by a predetermined air pressure.

Therefore, when the water introduced through the water inlet provided on one side of the valve body is supplied to the water through the water channel formed in the valve body, the cross-sectional area of the water channel due to the slow motion of the packing shaft is gradually reduced, through the water inlet. Inflow of water is gradually blocked while the flow rate of water supplied through the cross-sectional area is blocked.

As a result, the water flow is blocked little by little without blocking the flow of water, so that the water is not vortexed so that water hammering does not occur, and further, vibration and noise in the faucet bracket can be prevented.

As described above, the present invention does not suddenly block the channel of the faucet without suddenly blocking the water flow rate so that no water is vortexed and water hammering does not occur, thereby eliminating vibration and noise, and further, the failure rate of the faucet bracket. It can lower the lifespan and extend its life.
