SUMMARY OF THE INVENTION An object of the present invention is to provide a discharge state suitable for a use when a shower head for a bathroom containing a cartridge filled with a filter medium is used. It is to be.

[0005]

According to the present invention, a switching chamber is formed at the end of a flow path of a shower head, and a partition plate having two valve holes is accommodated in the switching chamber, and is connected to a switching button. In a bathroom shower head that alternately opens and closes two valve holes by moving a valve body, a cartridge filled with a filter medium and a first watering plate having a large number of large holes are attached below one of the valve holes. A second watering plate having a large number of fine holes is attached to the lower part of the other valve hole.

[0006]

When the first valve hole of the shower head is opened by operating the switching button, the fluid in the switching chamber discharges the filtered purified water through the cartridge, and the purified water is discharged from each large hole of the first watering plate. Since it discharges, it is possible to give a pleasant stimulus to the skin or the hair when washing or washing the body, and by closing the first valve hole and opening the second valve hole by moving each valve,
The fluid is discharged from each of the second watering holes, and since this fluid is a high-pressure flow, descaling can be quickly washed away when the bathtub is washed.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. In this embodiment, as shown in FIGS. 1 to 4, the shower head 1 has a horizontally long flow path 3 inside a handle 2,
A switching chamber 4 is formed at the tip of the flow path 3. A horizontal partition plate 5 is interposed in the switching chamber 4 and is fixed to the inside of the shower head 1 by screws 6 and 6. A substantially central portion of the partition plate 5 has a circular first shape. Valve hole 7 and second
The valve holes 7a are formed at intervals so as to be located on concentric circles around a shaft 9 of a switching button 8 described later.

As shown in FIG. 3, the seesaw-type switching button 8 has an opening 1 formed in a side surface of the shower head 1.
1 and a pair of valve bodies 14 and 14a are connected to the first valve by the elastic force of each spring 13 interposed in the holding portion 12 of the shaft body 9 connected to the switching button 8 so as to be partially exposed to the outside. It is press-fitted to a rubber plate 15 interposed between the hole 7 and the periphery of the second valve hole 7a. By pressing the protruding portion of the switching button 8, the valve bodies 14, 14a having an outer diameter larger than the valve holes 7, 7a move in the rotational direction around the vertical portion 10 of the shaft body 9, and One of the holes 7, 7a is connected so as to close it and the other is opened.

A cylindrical first cap 16 is screwed to the lower periphery of the partition plate 5 below the first valve hole 7, and a cartridge 17 filled with a filter medium such as activated carbon inside the first cap 16. And a disc-shaped first watering plate 18 supported at the lower part of the cartridge 17 is detachably accommodated.

At the lower part of the second valve hole 7a, a disc-shaped second
In order to prevent the fluid that has passed through the water spray plate 18a and the second valve hole 7a from diffusing to the surroundings in a state of being disturbed from the second water hole plate 18a and not discharging water, the water hole is located eccentrically with the second valve hole 7a. The rectifying plate 19 provided with the second cap 20 is a second cap 16a.
Is fixed to the lower peripheral edge of the partition plate 5 by screwing.

As shown in FIG. 4, a large number of large holes 21 having a hole diameter of about 0.7 mm are formed in the plane portion of the first water sprinkling plate 18 at a uniform density on the circumference. In the plane portion of the second watering plate 18a mounted side by side with the watering plate 18, a large number of pores 22 of about 0.4 mm smaller in hole diameter than the thick hole 21 are formed on the circumference. .

In the above configuration, in FIG. 1, the valve element 14a connected to the switching button 8 closes the second valve hole 7a of the partition plate 5 and is located at the position where the first valve hole 7 is opened. At this time, the fluid in the switching chamber 4 passes through the cartridge 17 containing the filter medium through the first valve hole 7, and the purified water from which chlorine, chlorine and the like contained in the tap water have been removed is purified by the first watering plate 18. Is discharged from the thick hole 21. This purified water is stored in cartridge 17
The water is discharged in a state where the water flow pressure is reduced due to the resistance when passing through, but a strong stimulus can be given to the body and the back of the hair by the large-diameter water discharged from a large number of large holes.

Next, in order to use a normal fluid that does not pass through the cartridge 17, when the switching button 8 on the side protruding from the shower head 1 is pressed, the valve bodies 14, 14a are centered on the vertical portion 10 of the shaft body 9. Move in the horizontal direction, and as shown in FIG. 2, the valve element 14 is located at a position where the first valve hole 7 is closed and the second valve hole 7a is opened. At this time, the fluid in the switching chamber 4 passes through the second valve hole 7a and the water flow hole 20 of the rectifying plate 19, and is discharged from the many fine holes 22 formed in the second water spray plate 18a. In this case, since the outer diameter of the pores 22 is smaller than that of the large holes 21, the water flow becomes a high-pressure flow having a small water flow and a high flow rate, and can quickly wash away descaling or the like when washing the bathtub.

[0014]

Since the present invention has the above configuration, it has the following advantages. (1) A switching chamber is formed at the front end of the flow path of the shower head, a partition plate having two valve holes formed therein is accommodated in the switching chamber, and the two valve holes are moved by moving a valve body connected to the switching button. In a bathroom shower head that opens and closes alternately, a cartridge filled with a filter medium and a first watering plate having a large number of large holes are attached below one valve hole, and a number of watering plates are provided below the other valve hole. By attaching a second watering plate with fine pores, clean water from which chlorine and chalk are removed by a cartridge during cleaning or washing of the body is discharged from the large hole to provide a pleasant stimulus to the skin and hair. In addition to being able to give water, it is also possible to discharge water from pores that do not pass through the cartridge by operating the switching button, and it is possible to quickly clean the bathtub.
