[0009]
Reference numeral 14 denotes a synthetic resin water discharge cap that is screwed onto the lower side of the water discharge main body 11. The central portion is closed by a closing member 15 to form a water stop channel S, and water is sprayed around the central portion. For example, a plurality of water spraying plates 17 are provided at the water discharge port of the water spraying channel 16 and the mesh is edged with a synthetic resin material.
[0010]
Reference numeral 18 denotes a synthetic resin diversion member built in the spout main body 11 , and includes a first chamber 19 closed by a closing member 15 and a second chamber 20 communicating with the water spray channel 16.
[0011]
Reference numeral 21 denotes a valve mechanism for switching between the water stop flow path S and the water spray flow path 16, as shown in FIGS. 4B and 3B, respectively, on the upper surface plate 18 a of the flow dividing member 18. In addition, valve seats 22 and 23 communicating with the water supply passage 13 are provided in correspondence with the second chambers 19 and 20, and the space on the upper side of the spout main body 11 is rotated around a vertical axis. A valve body holding member 24 made of synthetic resin is provided, and a metal ball valve body (stopping) is provided for selectively opening the valve seat channels a and b as the valve body holding member 24 rotates. The water valve body) 25 is provided by being biased in the valve closing direction by a spring 26, and a rotation operation tool (button) 27 is connected to the valve body holding member 24, and the operation tool 27 is connected to a water outlet. It is exposed on the lateral side of the main body 11. The rotating shaft portion of the operating tool 27 includes a pin 29 erected on the upper surface plate 18 a of the flow dividing member 18, a hole 30 with a groove 30 a formed in the rotating operating tool 27, and a fitting engagement with the hole 30. And a spline shaft 31 formed on the valve body holding member 24.
[0012]
According to the above configuration, as shown in FIG. 4, the valve seat channel a is opened by the selective valve opening operation of the valve seat channels a and b by the ball valve body 25, and the water stop channel S is opened. As shown in FIG. 3, it is possible to reliably switch between a water discharge state in which the valve seat flow path b is opened and the water supply path 13 is communicated with the water spray path 16. . In addition, 38 is an opening that forms the valve seat flow path a, and 39 is an opening that forms the valve seat flow path b.
[0013]
Further, a pressure reducing valve proposed by the present applicant in Japanese Patent Application No. 10-173603 (Japanese Patent Laid-Open No. 2000-9243) at the most upstream end of the flexible tube 4, that is, the mixed water supply tube 2a side of the flexible tube 4. 33 is provided. When the hair is washed by the pressure reducing valve 33, the operation lever 2d of the mixing plug main body 2 is sprinkled and the water is sprayed by operating the turning operation tool 27 of the hair washing shower 3. When the operation tool 27 is operated to stop water, when the pressure of the flexible tube 4 becomes higher than a predetermined pressure, the valve body 40 comes into contact with the seal packing 41 which is a valve seat to close the valve, thereby adjusting and stabilizing the water discharge amount. Can be achieved.
[0014]
In addition, the joint 42 of the simple attachment / detachment mechanism proposed by the present applicant in Japanese Patent Application No. 9-298771 (Japanese Patent Laid-Open No. 11-81400) is provided at the primary side inlet 43 of the pressure reducing valve 33. By adopting a simple attachment / detachment mechanism for connection with the joint 44 provided at the most downstream end of the supply pipe 2a, the mixed water supply pipe 2a and the flexible pipe 4 can be easily connected with one touch.
