However, all of these methods are difficult to install on water pipes, are difficult to adjust water volume, have complicated configurations and have limits on miniaturization, and require replacement with new ones. It had one or more of the following deficiencies: it was not easy to operate, it required extensive cleaning and repair work.

[Means for solving the problem] The present invention has a screwdriver insertion hole 2 in the center of the top wall of a tubular outer casing 1 whose upper surface is closed and whose lower surface is open, and the lower half of this insertion hole 2 is made slightly larger. Similarly to the diameter, the upper half is a first hexagonal hole 9' for fitting a hexagonal wrench, and a first male screw 3 is carved on the outer periphery of the outer casing 1, and a first female screw 4 is carved on the lower half of the inner peripheral surface. In addition, separately from the outer casing 1, a second female screw 5 is provided on the inner peripheral surface of the upper part, a second male screw 6 is provided on the outer peripheral surface of the lower part, and a second hexagonal hole 15 for fitting a hexagonal wrench is provided on the inner peripheral surface of the lower part.
A pipe body 8 is constructed in which a water guide hole 7 is formed in the middle part of the pipe body 8 to communicate with the inside and outside. The first female screw 4 is screwed into the second hexagonal hole 15 by fitting a hexagonal wrench into the second hexagonal hole 15 and turning it. A closed cavity 10 is formed surrounded by the inner wall of the casing 1, the ceiling wall of the outer casing 1, and the outer wall of the pipe body 8, and the top wall of the outer casing 1 has an inclined wall surface that is in contact with the cavity 10 with both upper and lower ends open. Directional water sprinkling holes 11 are opened, and separately from these, a water control piece 14 is constructed which has a driver groove 13 on the upper surface with a third male screw 12 carved on the outer peripheral surface of the upper half. 14 into the tubular body 8 from above, and the third male screw 12 is inserted into the second
The gist is that the water control piece 14 is screwed into the female screw 5, and the water control hole 7 is opened when ascending, and closed when descending, thereby solving all of the above-mentioned defects. The object of the present invention is to provide a nozzle device.

[Operations and effects of the invention] The invention is as described above, so it is difficult to install it on a water pipe, it is difficult to adjust the water volume, the structure is complicated and there is a limit to miniaturization, and it is difficult to replace it with a new one. It is possible to overcome all the deficiencies such as the lack of ease of operation and the need for extensive cleaning and repair work, and has the effect of fully achieving the intended purpose.

[Embodiment] In the embodiment shown in the figure, a driver insertion hole 2 is opened in the center of the top wall of a short tubular outer casing 1 whose upper surface is closed and whose lower surface is open, and the lower half of this insertion hole 2 has a slightly larger diameter. Similarly, the upper half is a first hexagonal hole 9' for fitting a hexagonal wrench, and the outer periphery of the outer casing 1 is provided with a first male screw 3, and the lower half of the inner peripheral surface is provided with a first female screw 4, respectively. Separately from the above-mentioned outer casing 1, a second female screw 5 is carved on the inner peripheral surface of the upper part, a second male screw 6 is carved on the outer peripheral surface of the lower part, and a second hexagonal hole 15 for fitting a hexagonal wrench is carved on the inner peripheral surface of the lower part. A pipe body 8 is formed, and has a water guide hole 7 in the middle part that communicates with the inside and outside.
is inserted into the above-mentioned outer casing 1 from below, and the second male screw 6 is screwed into the first female screw 4 by fitting a hexagonal wrench into the second hexagonal hole 15 and turning it. By fitting into the large diameter portion 9 of the insertion hole 2, the inner wall of the outer casing 1, the ceiling wall of the outer casing 1, and the tube body 8
A closed cavity 10 surrounded by the outer wall of the outer casing 1 is formed, and an inclined water sprinkling hole 11 with both upper and lower ends open is formed on the top wall of the outer casing 1 in contact with the cavity 10. 3rd male screw 1 on the outer circumferential surface of
A water control piece 14 having a screwdriver groove 13 on the upper surface with a number 2 engraved therein is constituted, and the water control piece 14 is inserted into the tube body 8 from above and the third male screw 12 is inserted into the pipe body 8 from above.
is screwed onto the second female screw 5, and the water control piece 14 opens the water guide hole 7 when ascending and closes it when descending. A hexagonal wrench is fitted into the first hexagonal hole 9' and screwed into the internally threaded riser pipe 17, which is provided upright, by turning the hexagonal wrench.
