A plurality of vent pipes 3' protruding from the liquid container 2 are provided, and opening/closing and the amount of ventilation can be adjusted by tightening and loosening plugs 3a. The plurality of ventilation holes 3 are
It may also be provided directly on the liquid container. 4 is the outflow hole and the connecting pipe 4
a. It communicates with the hot water passage 11 in the shower head via the valve part 5. The stopper 9 for opening and closing the valve portion 5 has a male screw portion 9′, a valve 10a, and a valve body 10b below a knob protruding from the upper end, as shown in the partial longitudinal exploded perspective view of FIG. 2b, The male threaded part 9' is threadedly fitted into the female threaded part 5' of the valve part 5, and the valve 10a is fitted into the valve seat 5a, and the valve chamber 7 is inserted from the connecting pipe 4a.
The valve body 10b closes the inflow hole 5a' to the valve chamber 7 and the communication hole 8 between the inside of the valve chamber 7 and the shower head, respectively, as shown in FIG. 2a. In the figure, 2a is a liquid inlet, 1
2 is a spray plate of the shower head, 12a is a small spray hole, and 13 is a shower hose.

In the shower device having the above configuration, when using the shower, the liquid container 2 is fixed and can be replaced or replenished with liquids such as various medicines and bath chemicals, and the liquid 10 is filled with the liquid 10, or the desired liquid is filled each time the shower is used. Open the vent 3 of the disposable liquid container 2 to which the liquid container filled with is attached using the stopper 3a, loosen the screw with the knob of the stopper 9, and open the inflow hole 5a' of the valve part 5 and the communication hole 8 of the shower head. By opening the liquid container to communicate the liquid container with the shower head and allowing hot water from the shower to flow out, the liquid flows out from the liquid container and is mixed with the hot water.

FIG. 2c shows another example of the valve portion 5, in which reference numeral 7' denotes a valve chamber.

Figures 3 and 4 show the second invention of the present invention, and the third
In the shower device shown in the figure, the liquid container 2 does not have a bottom plate and is fixed to the shower head 1 with each contact portion between the rotary gear plate 15 and the cover 11 kept watertight.
The rotary gear plate 15 has a larger diameter than the liquid container, and its gear meshes with the pinion 21, and the shaft 19 of the pinion
A blade 20 is attached so as to be integrally rotatable within the shower head, and the blade 20 is rotated by hot water flowing inside the shower head, a rotary gear plate 15 that is decelerated and rotated by a pinion 21, and a communication hole 15a for liquid outflow communicating with each other in the shower head. 16a in an eccentric position, and ventilation holes 15b and 16b are provided in the peripheral part of the rotary gear plate and the shower head.
It is designed to match and communicate with each rotation. Each of the communication holes and the ventilation hole communicate with each other through a communication pipe 17, and 17a
indicates the outlet.

In the figure, 14 is a connecting shaft. Incidentally, the liquid container 2 may be formed by molding the rotary gear plate into a single bottom plate so that it can be freely attached to and removed from the shower head, and when used, the liquid container 2 may be attached by opening a previously sealed communication hole so that the liquid container rotates together with the liquid container. . In addition, the blades 20 may be bent at the ends of each blade to ensure that they are exposed to hot water.
The diameter of the communication hole is determined experimentally based on the relationship between the density of the liquid, the amount of outflow, and the flow rate of hot water.

In the above-mentioned shower device, when the shower head is used, when pressure hot water flows in the direction of the arrow in the figure, the rotary gear plate 15 rotates, and the communication hole 15a,
16a, each time the vents 15b and 16b communicate, the liquid 10 in the container is mixed with hot water in a fixed amount from the outlet 17a of the communication pipe 17, resulting in a large number of spouts 12a.
Hot water mixed with liquid 10 is spouted out.
