Description of the Related Art A water or hot water shower device is provided with a water flow control opening / closing valve and is connected to the shower head to prevent water hammer generated when the opening / closing valve is closed by operating the opening / closing valve. The technique of providing a pressure reducing valve at the base end of the hose is disclosed in Japanese Utility Model Laid-Open No. 6-5588, but the structure is complicated and unnecessary when using a shower head other than a shower head having an open / close valve. On the contrary, when replacing the shower head with a new on-off valve, it is necessary to replace it with a hot and cold water mixing tap provided with this pressure reducing valve.

知される。The above-mentioned water hammer shock absorbing devices are mounted and installed at the base end of a hose, and are provided with an opening / closing valve provided in a shower head which is a source of water hammer, and the inside of the shower head around the valve and the hose. It does not directly absorb the shock caused by the sudden rise in water pressure inside.
Because it absorbs, there is a slight time lag in the start of shock absorption, during which momentary shock is sensed by the shower head and hose.

よって押圧されている。Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic sectional view of a shower head. The main body 2 of the shower head 1 has a hose mounting portion 2c, a water passage 2b, an opening / closing valve 5 attached, and a nozzle 3 attached by a mounting screw 4. The variable volume member 16, which is partitioned into the primary flow path 2 d and the secondary flow path 2 a,
a is communicated with the primary flow path 2d by the mounting member 9 and the water passage 9a, and is mounted and pressed by the pressing member 17 spring 8 on the secondary flow path 2a side.

ができる。[0008] A throttle valve 12 is provided in the water passage section 9a, and the inflow resistance of the variable volume member 16 into the inflow section 16a can be adjusted by adjusting the position of the valve tip 12a. It can be carried out,
The pressing force of the pressing member 17 and the spring 8 can be adjusted from the outside of the shower head 1 by the pressing force adjusting member 11.

無く容積可変部材１６は収縮した状態にある。When water or hot water is not supplied to the primary flow path 2d of the shower head 1, there is no water pressure in the inlet 16a of the primary flow path 2d and the secondary flow path 2a irrespective of the opening / closing operation of the on-off valve 5. 16 is in a contracted state.

積可変部材１６の膨張は制限されている。When the shower is used, water or hot water flows from the primary flow path 2d through the opening / closing port 5a by opening the on-off valve 5, and the secondary flow path 2a.
The water is discharged from the small hole 3a of the nozzle 3 through the water passage 2b. At this time, the water pressure of the secondary flow passage 2a is changed to the primary flow passage 2d and the inflow portion 16
Although the pressure becomes lower than the water pressure a, the expansion of the volume variable member 16 is restricted by the pressing member 17 and the spring 8.

される。When the on-off valve 5a is closed abruptly by the closing operation of the on-off valve 5 when using the shower and the water pressure in the primary flow path 2d rises sharply and a water hammer phenomenon occurs, the water or hot water flows into the primary flow path 2d. As the water pressure rises, the water enters the inflow portion 16a from the water passage 9a, and the pushing member 17 expands while receiving the resistance of the pushing force of the spring 8, and the variable volume member 16 expands. , The water flow resistance of the water passage 9a, and the pressure resistance of the pressing member 17 spring 8 and the variable volume member 16 reduce the sudden rise of the water pressure in the primary flow passage 2d, thereby preventing the water hammer phenomenon. At this time, the volume variable member 16 in the secondary flow path 2a
Is discharged from the small hole 3 a of the nozzle 3.

定できる。When the opening / closing port 5a is closed by the opening / closing valve 5, water or hot water is continuously supplied into the primary flow path 2d and a constant water pressure is maintained. 8, the expansion is limited in principle, but the difference between the water pressure in the primary flow path 2d and the water pressure in the secondary flow path 2a is larger than when the opening / closing opening 5a is open when the shower is used. Variable volume member 1
6, the expansion degree of the variable volume member 16 is set to a contracted state when the opening / closing port 5a is open when the shower is used, and a water hammer is prevented when the water pressure rises when the opening / closing port 5a is suddenly closed. When a constant water pressure is maintained in the primary flow path 2d, the pressure can be set in a range from a contracted state to a small expansion.

行うことが出来る。As described above, the showerhead device according to the present invention is provided with the flow rate adjusting unit. However, in order to prevent the water hammer phenomenon that occurs at the time of adjusting the flow rate, it is necessary to replace a hot / water mixer tap other than the showerhead device and supply the water pipe. It is not necessary to attach a shock absorbing device or a pressure reducing valve to the device or the like, and it is possible to replace only a new shower head device without fear of occurrence of a water hammer phenomenon in an existing shower device without a water hammer prevention device.
Further, the provision of the shock absorbing device in the shower head, which is the source of the water hammer phenomenon, at the position close to the flow rate adjusting section can more quickly prevent the water hammer.
