The outlet portion 13 is configured by attaching the outlet.

The inside of the case body 1 is divided into upper and lower sections by a partition wall 14, and a hole 15 is provided in the center of the partition wall 14.

In this embodiment, a rubber valve seat 16 whose upper surface forms a funnel surface is disposed at the center of the partition wall 14, and a valve hole 17 communicating with the hole 15 is provided at the center thereof.

A space located above the partition wall 14 and below the rubber holding plate 2, that is, a valve chamber 18, includes an inlet portion 8, a case body 1
and constitutes a part of the flow path 19 formed within the outlet portion 13.

A ball 20 is disposed within the valve chamber 18 and is seated on the valve seat 16 and freely moves within the valve chamber 18.

The ball 20 is positionally regulated by a regulating plate 21 provided upright on the partition wall 14 so that it can freely move only inside the regulating plate 21.

One side of the case body 1 has a support tube 22 disposed in the radial direction, and an operating rod 23 that moves forward and backward in the radial direction is disposed within the support tube 22.

This operating rod 23 is biased radially outward by a spring 24, and its distal end 25 is located within the valve chamber 18 and comes into contact with the ball 20, while its proximal end 26 is attached to the cam surface described later. It is in contact with 27.

An annular band-shaped guide groove 28 is provided on the outer peripheral surface of the case body 1.
A handle support ring 29 is fitted into the guide groove 28 and is rotatably supported but not vertically movable.

The handle support ring 29 is attached to the base end 2 of the operating rod 23.
6 has a ring discontinuity in the vicinity of a portion protruding from the outer circumferential surface of the case body 1, and a pair of nozzle support protrusions 30, 30 are formed at the discontinuity.

A nozzle 32 is supported by the pair of nozzle support protrusions 30, 30 via a pivot 31 so as to be movable up and down.

A portion of this nodule 32 supported by the pivot 31,
That is, the operating portion 33 includes a cam surface 27 that slides into contact with the base end portion 26 of the operating rod and whose unevenness changes in the direction of rotation of the handle 32.
It has an imposing shape.

Although the tip of the handle 32, that is, the operating section 34, is bent into an L-shape, the shape of the operating section 34 can be freely selected.

The cam surface 27 has a shape as shown in FIG.
When the handle 32 is positioned upward, the operating rod 23 is biased by the spring 24 and moves backward, and accordingly, the cam surface 27 and the operating rod base end 26 are brought into a position where the ball 20 closes the valve hole 17. The first contact point is
As shown by the imaginary line in the figure, when the handle 32 is rotated 90 degrees downward and positioned horizontally, the contact point moves to the right in FIG. It is configured such that the valve hole 17 can be opened by moving it to the position shown in FIG.

Moreover, when viewed from above as shown in FIG. 3, the cam surface 27 has the following:
The amount of protrusion of the most protruding line a is configured to vary along the circumferential direction of the case body 1.

In this embodiment, the most protruding line a is shaped to run obliquely, and the nozzle supporting ring 29 is moved in the direction P in FIG.
Furthermore, when the handle 32 is rotated, the stroke of the operating rod 23 corresponding to the up and down operation of the handle 32 becomes smaller, and conversely, when the handle support ring 29 is rotated in the direction Q in FIG. Operating rod 2 corresponding to
The stroke of 3 is made to be large.

For example, when the handle support ring 29 is rotated to the maximum in the P direction, the cam surface 27 and the operating rod base end 2
However, if the stroke of the operating rod 23 is set to zero at this time, the operating rod 23 will remain stationary to the left in the figure regardless of whether the nozzle 32 is moved up or down, and the valve hole 1
7 is always closed by the ball 20 to maintain a watertight state.

On the other hand, when the handle support ring 29 is rotated to the maximum in the Q direction and the handle 32 is rotated downward, the cam surface 27 and the operating rod base end 2'6 come into contact at point B. As a result, the operating rod 23 and the ball 20 move as far as possible to the right in the drawing, and as a result, the opening degree of the valve hole 17 and the flow rate become maximum.

In this case as well, when the handle 32 is rotated upward, the ball 20 closes the valve hole 17 and the water is cut off.

As described above, in this embodiment, water can be shut off and water can be turned on with a single touch by moving the handle 32 up and down, and the handle 32 and the handle support ring 29 can be rotated around the case body. The flow rate can be adjusted.

In the figure, 36 and 37 are O-rings for sealing, and 38 is a mesh filter fixing ring.

A second embodiment of the present invention shown in FIG. 4 is a modification of the first embodiment, in which positioning recesses 39, 39 are
. . . are provided so that the flow rate can be determined in stages in response to the rotational operation of the handle support ring 29.

In the third embodiment of the present invention shown in FIGS. 5 to 7, the operating rod 23 is moved forward and backward by a handle 32 that rotates left and right, so that the ball 20 can be held at the valve opening position or the valve closing position. It is something.

In this embodiment, a handle support column 40 is provided on one side of the case body 1 so as to protrude in the radial direction, and a flanged support cylinder 41 is fitted and fixed to this handle support column 40 with screws 42. A nozzle 32 is attached to a flanged support tube 41 so as to be rotatable left and right.

Further, as shown in FIGS. 7 and 8, the inner surface of the base of the handle 32, that is, the handle operating portion 33, is provided with a cam surface 27 that changes in concavity and convexity in the direction of rotation of the handle 32.
The base end 26 of the operating rod 23, which is biased by a spring 24, is in sliding contact with the base end 26 of the operating rod 23.

When the handle 32 is thus rotated in the S direction to the position shown by the imaginary line in FIG. 6, the cam surface 27 also moves in the S' force direction in FIG. 7, pushing out the operating rod 23 and releasing the ball. 20 is moved to the position shown by the imaginary line in FIGS. 5 and 7 to bring the valve into the open state.

When the handle 32 is further rotated in the S direction, the ball 20 moves further to the left in the figure, and the opening degree of the valve hole 17 becomes larger.

On the other hand, when the handle 32 is reversed in the R direction and returned to the position shown by the solid line in FIG. 6, the operating rod 23 retreats and the ball 20 closes the valve hole 17.

As described above, in this embodiment, the water stop operation and the water flow operation can be performed with one touch by rotating the bundle 32 left and right, and the flow rate can be adjusted by selecting the amount of rotation of the bundle 32 during the water flow operation. be able to.

In this embodiment, parts common to those in the first embodiment are designated by the same reference numerals.

Also, 43 is a cover, 44 is a Java plate retaining ring, 45
is an O-ring for sealing.

The present invention can be configured in various ways other than those shown in the above embodiments. For example, the bundles of the first and second embodiments can be formed into a shape as shown by the imaginary line in FIG. 4. Moreover, it is possible to form a recess similar to the positioning recess shown in the second embodiment on the cam surface of the bundle of the third embodiment.

As described above, the present invention has a cam surface that changes concavity and convexity in the rotational direction of the bundle on the operating part of the bundle that operates the forward and backward movement of the operating rod, and the base end of the operating rod is brought into sliding contact with the cam surface. Since at least a water stop valve is configured, the water can be stopped or passed instantly by one-touch operation of the bundle, and the amount of water flowing can be easily adjusted.

Further, according to the present invention, the water stopping operation and the water flow rate adjusting operation can be performed with one member (bundle), so that the structure can be simplified.
