BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shower head which can be used as faucet water.

[0002]

2. Description of the Related Art There have been many proposals for shower heads usable as faucet spouts (for example, Japanese Utility Model Publication No. 44-19320, Japanese Utility Model No. 48-17161, Japanese Utility Model Publication No. No. 51-53866 and Japanese Utility Model Publication No. 52-1400). Needless to say, such a shower head is used in a bathroom or a washroom by switching between a shower for hair washing and the like and an axial water discharge such as a normal faucet by a switching valve. Recent shower heads have made this switching one-touch and lightened. For example, the above-mentioned 48
As shown in Japanese Patent Publication No. -17161,
A switching valve in the form of a disk is built in the head, and the switching is performed by rotating the disk valve by a handle provided on the back of the shower head. Therefore, shower
There is a problem that the aesthetic effect is spoiled only by the protruding handle on the outside of the head. Therefore, the present inventors,
The handle for the switching valve was stopped, and a cylinder valve was adopted to develop a push-button switching valve. When the faucet was discharged axially from the open end of the cylinder valve, the faucet was transparent. There is a problem that the water is lacking (water is discharged in a turbulent manner).

And flows into the communication hole 13 from the outer periphery of the cylinder valve 4 to discharge water from the spray port 8. When the faucet push button 19 is pressed when the faucet is used for faucet spouting, the cylinder valve 4
As shown in FIG. 2, the O-ring packing 14 fits into the notch step 16 and the hot water in the donut-shaped flow path 10 flows into the communication hole 18 and is discharged from the faucet discharge port 7.

[0006]

According to the present invention, the cylinder valve is simply pressed and slid to switch between the water discharge for the shower and the water discharge for the faucet. Not only does it not hurt the appearance,
Since the spout water is discharged directly from the open end of the hollow portion of the cylinder valve, the flow of water is as direct as possible even though it is a shower head, and the spout for the faucet has a large diameter compared to the size of the head of the shower head. An outlet can be formed, and a large amount of faucet water can be obtained. In addition, since the hot and cold water flowing into the hollow portion can be prevented from colliding with each other with a simple tongue-shaped rib, the faucet water can be made transparent without turbulence.
