And a horizontally long flow path 5 provided inside the connecting portion 4. The flow path 5 is provided at a lower end portion of a lower end of a partition wall 6 through a water guide hole 7 with a rectifier 9 interposed therebetween. A switching chamber 8 communicating with the road 5 at a substantially right angle is formed.

The branch cylinder 11 screwed to the female thread 10 on the peripheral surface of the switching chamber 8 has a cylindrical DC water discharge section 12 which is opened directly below the water introduction hole 7 at the center thereof. A water passage 14 is formed in the periphery, and a valve body 15 for switching the flow path to the valve hole 13 or the water passage 14 side by opening and closing the valve port 13 of the DC water discharge unit 12 is movably facing in a parallel direction. An external thread 16 is engraved on the outer peripheral surface.

A seesaw button 17 is interposed in an opening 18 formed in the side surface of the head 1 so that a part thereof is exposed to the outside. The button 17 is connected to the valve body 14 by a shaft 19 and the button 17 projects. By pressing the part that is
Move in a parallel direction and open and close the valve port 13 of the DC water discharge section 12.

The water sprinkling member 20 has a hollow cylindrical shape. As shown in FIG. 3, a large number of water sprinkling holes 22 are formed at regular intervals in a ring shape inside a flange portion 21 formed at the bottom, so that the fluid can be sprinkled. 1 and a central hole 25 communicating with the valve port 13 of the DC water discharge portion 12 is opened at the center as shown in FIG. 1, and the water sprinkling member 20 is provided with a female screw cut in the upper inner peripheral surface. The part 27 is connected to the male screw part 16 of the branch cylinder 11.
And is detachably mounted on the head 1.

The plate 28 is substantially disc-shaped and the packing 29
Through the flange portion 21 and the center hole 25 of the watering member 20
A large-diameter hole which is seated on the annular seat 26 on the upper surface and is urged downward by a spring 34 interposed between the branch tube 11 and a slightly outer periphery from the center and communicates with the valve port 13 of the branch tube 11. Around the large-diameter hole 30, a number of small holes 31 are formed in a ring shape, which are vertically communicated with the water sprinkling passage 14, and below each of the water sprinkling holes 22 of the water sprinkling member 20. A plurality of projections 32 projecting toward the projection 32 are protruded. In this case, the flow path of the fluid is formed as shown in FIG.
It is formed as a ring-shaped flowing water channel 24 between the two peripheral portions 23.

The plate 28 is provided with the flange 21 and the annular seat 26 of the water sprinkling member 20 and the DC water discharge part 1 of the branch cylinder 11.
The lower end 2 is interposed between the lower end surfaces of the plate 21 so as to be movable up and down against the urging force of the spring 34, and normally sits on the flange portion 21 and the annular seat 26 as shown in FIG. 1 and projects downward from the center of the plate 28. When the knob 33 is pressed from below the watering member 20, the plate 28 rises against the urging force of the spring 34 as shown in FIG.
0 can be kept away from the watering hole 22.

When the plate is sandwiched and fixed between the sprinkling member and the branch tube without any gap, the plate can be moved up and down by rotating in a loosening direction as in the case of removing the sprinkling member from the branch tube. In this way, the plate may be raised by pressing the knob from below the watering member.

In the above configuration, in FIG. 1, the valve body 15 of the head 1 is located at a position where the valve port 13 of the DC water discharge section 12 is closed. At this time, the fluid in the switching chamber 8 drops from the sprinkling channel 14 of the branch tube 11, and passes through the small hole 31 of the plate 28 and the peripheral surface of the projection 32 and the peripheral portion 23 of the sprinkling hole 22 of the water sprinkling member 20.
The liquid is discharged to the outside from a ring-shaped flowing water channel 24 formed between them. The fluid discharged from the water sprinkling holes 22 formed in a large number in the water sprinkling member 20 has a small diameter and a thin ring shape, so that the fluid becomes a fine mist, and the fluid is vigorously applied to tableware and the like under the head 1 at a high pressure. Even if hit, water splash can be reduced.

Next, the button 17 on the side protruding from the head 1 is pressed, and the valve body 15 is moved in the horizontal direction so that the switching chamber 8 is moved.

The fluid drops vertically from the water introduction hole 7, and can be discharged to the outside as a direct current from the center hole 25 of the water spray member 20 through the large-diameter hole 30 of the plate 28.

If the water spouting direction from each water sprinkling hole 22 of the water sprinkling member 20 becomes uneven, it is considered that the water sprinkling hole 22 is clogged.
If the knob 33 is pressed several times from the lower part of the zero, foreign substances adhering around the watering hole 22 can be removed and washed away.

In the shower head of the above-described embodiment, the flow path of the fluid can be switched between the shower water and the DC water by operating a button, but only the shower water is discharged from the sprinkling member of the shower head having no switching function. You may make it.

[0017]

The shower head according to the present invention accommodates a plate having projections formed in the watering holes inside the watering member, and has a ring shape formed between the peripheral surface of the projections and the peripheral edge of the watering holes. Since the shower water is discharged from the running water channel, a thin, ring-shaped fluid can be discharged in the form of a mist from the sprinkling hole, and there is little water splash when the shower water hits the articles, In this case, the usability is good and the workability can be improved.

Further, the plate is vertically movably mounted between the water sprinkling member and the branch tube screwed to the head, and is moved up and down by operation of a knob formed so as to protrude downward, so that the projection is moved to the water sprinkling hole. Since the water sprinkling hole of the water sprinkling member is clogged with foreign matter, the foreign matter can be removed by pressing the plate knob from the lower part of the water sprinkling member during water flow.
