2. Description of the Related Art In general, in a water tap device, a cock provided at the top is twisted by hand, an on-off valve provided therein is opened / closed, and water supply / stop is performed. Twist the cock by hand to drain the water from the faucet, wash your hands, then grasp the cock again by hand and twist it in reverse.

[0003] However, the hand for twisting the cock and supplying tap water is dirty, and even after touching the cock with the dirty hand and washing the hand, touching the cock again does not allow the washed hand to be cleaned again. It will be soiled by a dirty cock and is not hygienic.

In order to solve such a problem, there has been proposed a faucet device in which an operation lever is protruded from a faucet and water is discharged and water is stopped by operating the operation lever (for example, see, for example, Japanese Patent Application Laid-Open No. H11-157556). 50-144,
No. 327, No. 58-33, 872 and No. 3
606).

In the faucet device disclosed in Japanese Utility Model Laid-Open Publication No. 50-144,327, when the water discharged from the faucet and the water stored in the container becomes full, the water stop valve is operated by water pressure to automatically stop water. It is like that. 58-33
The faucet device disclosed in Japanese Patent No. 872 measures the amount of water flowing out of the faucet, and automatically stops water after flowing a predetermined amount of water.

In the faucet apparatus disclosed in Japanese Utility Model Publication No. 3-606, a water turbine is rotated by water flowing out of the faucet, and after a predetermined amount of water flows, a water stop valve is operated to automatically stop water. Things.

[0007]

[Problem to be solved by the present invention]
In the faucet device of No. 144,327, it is necessary to always keep a predetermined amount of water in a container in order to stop water, and there is a problem that the water cannot be stopped unless water is accumulated in the container. The faucet device disclosed in Japanese Utility Model Laid-Open Publication No. 58-33,872 or Japanese Utility Model Publication No. 3-606 requires a gear mechanism for measuring the amount of water, requires a large number of parts, increases the size of the apparatus, and has a complicated structure and cost. There is a disadvantage that it is disadvantageous.
Further, the above-mentioned faucet device is hygienic, but when adjusting the water discharge amount, the water amount cannot be adjusted unless the cock provided on the top is twisted by hand, so that the cock touched with dirty hands It has to be touched again, and there is a problem that it is not sanitary when it is attempted to adjust the water discharge amount again after adjusting the water amount once. Further, since the water supply and the water stop are automatically performed, there is a problem that the water discharge and the water stop cannot be freely controlled by the worker's intention. The present invention has been made in view of the above-described problem, and can supply a desired amount of water for a desired time with a simple operation, and can perform the operation without stopping a water discharge without touching a cock or the like. It is an object of the present invention to provide a faucet device that can easily change the amount of water during use and is controlled in multiple stages by one sanitary operation lever.

[0008]

In order to achieve the above object, the present invention provides an O.D.
A support attached via a ring, a cylindrical valve seat portion supported by the support and having a water opening in the center, a valve body repelled by a spring to close the water opening, A valve body having an O-ring fitted into an annular groove formed on the lower surface of the plate portion of the valve body and a valve sleeve provided at a lower portion of the plate portion, and an outlet opened at a lower end of the support A main operation rod provided so as to protrude further, and a flat plate portion having an opening provided integrally with the main operation rod and provided so as to abut on a flat portion at the lower end exit of the support. An operation mechanism including an operation lever, a flat plate portion mounted on the flat plate portion and having an opening, and a driven operation lever including a driven operation rod integrally provided with the flat plate portion; and the valve seat. Form a flat vertical wall in the channel in the annular body attached to the section A control groove for controlling opening and closing of the valve body with respect to the valve seat portion is formed on the vertical wall, and a plurality of projections for setting the position of the valve body with respect to the main body of the control unit are formed in the control groove. And a control part which fits one end of a pin so as to be able to move in the control groove in one direction by overcoming these protrusions, and to lock the other end of the pin to the valve body part, The driven operation rod of the driven operation lever is fitted in the valve sleeve of the valve body, and the driven operation rod can be slid only in the vertical direction. It is a faucet device. The valve body has a pipe having an opening formed therein, and a guide piece formed by halving the upper portion of the pipe, and a pair of parallel pieces formed with the guide piece on the vertical wall. It is preferable to insert into a suitable guide groove.

[0009]

In this way, once the cock is twisted to the water discharge state, the water supply-water stoppage and the amount of water can be adjusted by operating one operating lever that is washed with water. The faucet device can be operated without touching it, which is hygienic. In particular, since the amount of water discharge can be controlled in a plurality of steps in accordance with the amount of tilt of the operation lever, the operability is extremely improved. For example, when the first stage water discharging operation in which the operation lever is slightly tilted is performed, the water is discharged slightly, and the water discharge is immediately stopped when the operation lever is released. Next, when the second-stage water discharging operation in which the operation lever is further tilted than the above-described state is performed, the amount of water discharged further increases, the state is locked, and a predetermined amount of water is discharged for a desired time. If the third-stage water discharging operation in which the operation lever is tilted can be performed, the water discharge amount can be further increased, the state is locked, and a predetermined amount of water can be discharged for a desired time. . When the water is stopped during the second and third stages of the water discharging operation, the lock is released by tilting the operation lever, and the water returns to the original state easily, so that the water can be stopped. Therefore, water supply-water stoppage and water volume adjustment can be performed by operating one operation lever that is washed with water during water discharge, and it is extremely sanitary without touching the cock. Further, since no gear or the like is used, the structure is simple and the cost is advantageous.

b is projected. Flat plate part 31 of main operation lever 311
1a abuts on the flat portion 35 near the outlet 34 formed by narrowing the lower end of the second support member 22, and when the lower end portion of the main operating rod 311b is tilted, the flat portion 35 is used as a fulcrum. That is, the main operation lever 311 can be operated based on the so-called "leverage" principle. The main operation lever 311 and the driven operation lever 312 are separate bodies, and when the main operation rod 311b is tilted, the driven operation lever 3
Reference numeral 12 follows this, and moves only in the vertical direction regulated by a valve body 41 described later.

The valve body portion 40 is sandwiched between the lower ends of the elbow pipe portions 13 by the first support body 21 and has a water passage H at the center thereof.
The valve body 41 has a cylindrical valve seat portion 42 in which is opened, and a valve body 41 which is repelled by a spring 43 so as to close the water inlet H. The valve body 41 has an annular groove 412 formed on the lower surface of the flat plate portion 411, and an O-ring O is fitted inside. A valve sleeve 413 is formed at a lower portion of the valve body 41, and a pipe 414 is provided at an upper portion thereof. Valve sleeve 413
Is provided inside the driven operation rod 31 of the driven operation lever 312.
2b is fitted relatively honey so that the driven operation rod 312b can slide only in the vertical direction. As shown in FIG. 2, the pipe 414 formed on the upper portion of the flat plate portion 411 is formed by dividing a base annular portion 414a having a plurality of openings h and an upper half of the base annular portion 414a in half. And a formed guide piece 414b. And the guide piece 414b
Are fitted in a guide groove 56 of the control unit 50 described later. However, the guide piece portion 414b serves to prevent the valve element 41 from rotating, so to speak. The guide piece portion 414b does not necessarily need to be in a fitted state with the guide groove 56, but simply in contact with a vertical wall 53a described later. There may be.

The control section 50 is a section for controlling the valve element 41 operated by the operation lever 311. As shown in FIGS. 2 and 4, the screw section 4 at the upper end of the valve seat section 42 is provided.
An annular lower half 5 having a threaded portion 51a screwed to 2b
2 and an upper half 53 integrally formed with the lower half 52. It has a main body 54 having a generally frustoconical cylindrical shape. A pair of parallel guide grooves 55 and a substantially diamond-shaped control groove 56 are formed in a vertical wall 53a formed in the upper half portion 53 of the main body 54. The tube 414 is inserted into the lower half 51a, and the guide piece 4 after the lower half 51a is inserted.
14b is inserted into a pair of parallel guide grooves 55, and has a function of preventing rotation of the valve body 41 itself.

The guide piece 414b and the vertical wall 5
A portion defined by 3a is a water flow passage, and water flows through the passage having a semicircular cross section. As shown in FIG. 3, the control groove 56 has a multi-stage control groove 56a having a rhombic shape and a vertical groove 56b connected to the multi-stage control groove 56a. One end of 57 can slide. The other end of the pin 57 is engaged with the annular lower half 52 of the tube 414. The vertical groove 56b is a portion used when performing the first-stage water discharge, and is used when the valve body 41 is slightly opened. Diamond shaped multi-stage control groove 56a
Is a portion used when the valve element 41 is controlled in multiple stages, and is a vertical projection T ₁ , which is erected from the bottom of the groove.
T ₂ the tip of the pin 57 engages with the, so as to set the position of the valve element 41 relative to the body 54 of the control unit 50. Therefore, although the projections T ₁ and T ₂ are formed at two places, the projections T ₁ and T ₂ are configured to be unable to retreat so that they can move in only one direction by the pin 57. Have been.

Next, the operation of the above embodiment will be described. FIG.
In the state shown in (1), the faucet device is in the water stop state. From this state, when the main operation rod 311b of the faucet device 10 configured as described above is lightly pressed to set the water discharge state at the first stage,
As shown in FIG. 5, the main operation lever 311 has a so-called “lever” with its flat plate portion 311 a having the flat portion 35 as a fulcrum.
Tilted on the principle of Since the main operation lever 311 and the driven operation lever 312 are separate bodies, the main operation lever 311
11b, the driven operation lever 312 is restricted by the valve sleeve 413 of the valve body 41,
To move slightly upwards. That is, the guide piece 414b of the pipe body 414 slides along the parallel guide groove 55 of the control unit 50, and the valve body 41 moves upward surely. At this time, since the tip of the pin 57 is engaged with the vertical groove 56b, the pin 57 simply moves up and down in the vertical groove 56b. At this time, the passage between the vertical wall 53a and the guide piece 414b becomes a water flow passage, and flows down through the water passage H of the valve seat 42 through the passage. In this state, since the valve element 41 is only slightly opened, the amount of water is extremely small.

As shown in FIG. 6, the main operation rod 311
b, the main operation lever 311 is moved to its flat portion 3
11a is further tilted with the flat portion 35 as a fulcrum.
Due to the movement of the main operation lever 311, the driven operation lever 312 is moved upward by being guided by the valve sleeve 413, and accordingly, the valve element 41 is further moved upward. Therefore, the valve body 41 further expands the water passage H of the valve seat, and the amount of water discharge increases.

At this time, the tip of the pin 57 is moved from the vertical groove 56b of the control groove 56 to the first vertical protrusion T _1.
The engaged, since the locked to the protrusion T _1, the valve element 4
The position of the first valve seat will be maintained. However, when the pressing force of the main operation rod 311b is released, the valve body 41 is released.
Is in the closed position, and the main operation levers 311 and 312 return to the state shown in FIG. To stop water discharge in this state, the main operation rod 311b may be further pressed. Thus the tip of the pin 57 is moved further upward from the first projection T _1, reaches the vertical groove 56b of the control groove 56 after one revolution, the water stop state shown in FIG.

As shown in FIG. 7, the main operation rod 311
b, the main operation lever 311 is moved to its flat portion 3
11a is further tilted with the flat portion 35 as a fulcrum, and the valve body 41 makes the water passage H of the valve seat almost fully open, so that the amount of discharged water is maximized. At this time, the tip of the pin 57 is
It will move past the second protrusions T ₂ of the. To maintain this maximum water discharge state, the pressing of the main operation rod 311b is released. As a result, as shown in FIG.
Tip 7 would be locked to the second protrusion T _2.
As a result, the valve element 41 holds the main operation lever 311 and the driven operation lever 3
12 is returned to the original position by the force of the spring 33 and its own weight, and the main operating lever 311 is washed by the flowing water.

Finally, when the main operation lever 311 and the driven operation lever 312 are slightly pressed from the maximum water discharge state in which the main operation lever 311 is returned to the original position, as shown in FIG.
The operation of the main operation rod 311b is performed by the valve sleeve 41 of the valve body 41.
3 and the main operation rod 311b are fitted to each other to make the valve sleeve 413
, The tip of the pin 57 easily comes off the protrusion a of the control groove 56, passes through the control groove 56, and returns to the vertical groove 56b. The valve sleeve 41
If the internal space of the valve 3 and the internal space of the valve seat 41 are communicated with each other by a small hole (not shown), the movement of the driven operation rod 312b becomes smooth and the sudden operation of the driven operation rod 312b is prevented. The valve sleeve 413 and the main operation rod 311b operate integrally, and the engagement of the pin 57 can be easily released.

The present invention is not limited to the above-described embodiment, but can be variously modified within the scope described in the claims of the present invention. For example, if the valve element 41 can be prevented from rotating, the guide piece 414b formed by dividing the upper part of the pipe 414 in half and the pair of parallel guide grooves 55 formed on the vertical wall 53a do not necessarily need to be inserted. Or simply in a contact state.

[0023]

As described above, according to the present invention, the degree of opening of the valve body can be adjusted by the amount of pressing the operation lever, whereby the hands can be washed while adjusting the amount of water flowing out of the faucet. After washing, water can be easily stopped by operating the operation lever, so that a desired amount of water can be supplied and arbitrary stop can be performed by a simple operation. Further, the adjustment of the time from the opening to the closing of the valve is arbitrarily determined by the user, and a mechanism for adjusting the water discharge time is not required, so that the structure is simplified. Further, the operation lever can be washed with water while the hands are being washed, and the cock is not touched when the water discharge is stopped, so that the faucet device is excellent in sanitation.
