DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shower head having a water stopping function which is used in a sink or a vanity stand, and which switches a hot water flow path or enables water stop by operating a button.

[0002]

2. Description of the Related Art Conventionally, there has been known a shower head having a water-stopping function capable of switching a flow path of hot and cold water spouted from a shower head to two types of water spouting forms depending on the use, and further enabling water stoppage. FIGS. 1 and 2 of JP-A-2000-154565 (FIGS. 9A and 9B of the present application) are available. 9 (a) and 9 (b), the shower head 73, which is supported at the tip of the holder 72 of the mixing faucet 71 so as to be freely drawn out, has a button 74.
A holding member 84 connected to the flow path 75 is movably interposed in a switching chamber 78 formed at the lower part of the flow path 75, and the switching chamber 78 is formed by a water blocking hole 77 drilled at the upper portion substantially at the center of the partition wall 76. 75, a first valve hole 80 communicating with the first water discharging portion 82 and a second valve hole 81 communicating with the second water discharging portion 83 are formed in the partition plate 79 mounted at a lower portion at intervals. The holding member 84 is provided with a water stop valve 8 by a spring 85 housed therein.
6 and the switching valve 87 are elastically pressed up and down,
Is in the center position, the water stop valve 86 closes the water stop hole 77, the supply of hot water from the flow path 75 to the switching chamber 78 is shut off, and the water stop state is reached. By moving the holding member 84 to the other side, the water blocking hole 77
Is opened, and the first valve hole 80 or the second valve hole 81 is opened and closed by the switching valve 87, so that hot water can be discharged from the first water discharging portion 82 or the second water discharging portion 83.

[0003] The above-mentioned shower head is used when water is stopped and a flow path is switched by a holding member connected to a button.
To stop the supply of hot and cold water supplied from the flow path to the switching chamber, a spring is used to elastically press the water stop valve upward to stop the communication between the upstream flow path and the downstream switching chamber. Although the water hole is closed, since the water stop valve receives high hot water pressure from the upstream side, it is necessary to increase the elastic force of the spring to ensure the water stop, and the higher the elastic force, the more the water stop valve The closeness of the water blocking hole is high and it is possible to reliably stop water, but the movement resistance of the holding member in the parallel direction at the time of switching the flow path becomes large, the switching operation of the button is heavy, and the operability is poor. There was a problem of becoming.

[0004]

A problem to be solved by the present invention is to switch the flow path of hot and cold water to a first water hole or a second water hole by operating a button, and to further stop water. In a shower head with a water function, operability is improved so that a button can be operated lightly when switching to any of a water discharge position or a water stop position.

[0005]

SUMMARY OF THE INVENTION According to the present invention,
The flow path of hot and cold water and the switching chamber in the shower head with a water shutoff function that switch the flow path of hot and cold water to the first water hole or the second water hole by the operation of the button and further enable the water stop. The formed shower head body is provided with a diversion tube having a first valve port and a second valve port mounted in a switching chamber, and a valve body for opening and closing each valve port formed in the diversion cylinder in the switching chamber. A valve body retainer containing a spring that elastically presses the valve body is housed in connection with the button, and a first water hole communicating with the first valve port and a second water hole communicating with the second valve port are provided. Attach from the bottom with a water discharge cylinder with two water holes formed so that the water discharge form is different,
By operating the button, the valve body closes one of the two valve ports and opens one valve port to discharge water from any of the water holes, or simultaneously closes the two valve ports. This made it possible to stop water.

According to a second aspect of the present invention, the first water hole is a direct current hole, and the second water hole is a foam hole.

According to a third aspect of the present invention, the button is exposed to the outside through an opening opening in the front of the shower head main body, and can be operated from the front.

A sealing material 32 such as a ring, packing, or the like is attached, and a fitting hole 33 opened in the center is formed in the small-diameter disc portion 1
5, an annular cylindrical portion 34 is formed integrally with the outer periphery of the fitting hole 33 so as to protrude upward from the peripheral edge thereof, and a number of small holes 37 are formed in the annular portion 35 on the peripheral surface. A plurality of water passages 36 formed in a large number in the vertical direction are formed at equal intervals.

A substantially ring-shaped strainer 38 is superposed on the foam plate 30. The strainer 38 covers the annular portion 35 of the foam plate 30 from above, and the hot and cold water supplied from the second valve port 14 of the flow dividing tube 8 is removed from the foam plate with the foreign matter removed by the mesh of the strainer 38. 3
The hot water flows through a number of small holes 37 and is supplied downward at an increased flow rate.

As shown in FIGS. 1 and 2, the water discharge cylinder 39 has a cylindrical shape with an open upper portion, and a female screw portion 4 formed on the inner periphery of the upper portion.
0 is mounted in a watertight manner by screwing a male screw part 7 formed on the outer periphery of the lower part of the shower head main body 1 with a sealing material 41 such as an O-ring or packing therebetween, as shown in FIGS. 4 and 5. A DC tube 42 having a cylindrical shape vertically communicating with the DC water discharge portion 18 of the flow dividing tube 8 is formed in the portion.
, A plurality of rectification networks 44 are superimposed and held, and DC water can be discharged to the outside from the first DC water holes 43. Further, an annular storage portion 45 is formed on the outer periphery of the DC tube 42, and second water holes 46 for foam vertically communicating with the water passage portion 36 of the foam plate 30 are formed at equal intervals in the circumferential direction. A plurality is formed. Further, a plurality of foam nets 47 covering the second water holes 46 from above are fitted into the storage portion 45 in a state where a plurality of foam nets 47 are superimposed on each other. The hot and cold water strikes the foam net 47.

In this case, the flow rate of the hot water in the switching chamber 4 is increased by the number of small holes 37 in the water passing portion 36 of the foam plate 30 and the foam net 47 before the water is discharged from the second water passing hole 46 to the outside. When the air introduced from the air introduction hole 48 of the water discharge tube 39 is mixed into the hot water passing through the water, the hot water is satisfactorily foamed, and the foam water is discharged from each of the second water holes 46. Water is low in sound of running water and dropping sound to a sink and the like, and is capable of discharging a soft water flow with little water splash in a wide range, which is convenient for washing tableware.

Further, when the second button 21a exposed from the front of the shower head main body 1 is pressed from the state shown in FIG. 7, the second button 21a connected to the second button 21a as shown in FIG.
The valve body holder 24a is connected to the second valve body 2 around the valve shaft 26a.
9a moves in the horizontal direction. In this case, since the first valve body 29 is arranged right and left with the second valve body 29a, the second valve body 29
a to move in the same direction, the first valve element 29 closes the second valve port 14, and the second valve element 29a closes the first valve port 13 to be in a water-stop state.

In this embodiment, DC water and foam water are discharged from the two water holes. However, other water discharge modes may be adopted.
For example, watering, massage water, or mist water may be discharged.
