When screwed together, the tube 8 is inserted into the large diameter section 5 and its lower end is fitted into the upper opening of the narrow diameter section 2, so that the inner wall of the large diameter section 5, the lower surface of the lid 7, and the tube 8 A closed cavity 13 is formed surrounded by the outer wall of the lid part 7, and an inclined water sprinkling hole 14 with both upper and lower ends open is formed in the wall adjacent to the cavity 13 in the lid part 7. A water control piece 1 having a driver groove 16 on the upper surface and a third male screw 15 carved on the outer peripheral surface of the water control piece 1.
This water control piece 17 is inserted into the pipe body 8 from above, and the third male screw 15 and the first female screw 10 are screwed together. The object of the present invention is to provide a new nozzle device which solves all of the above-mentioned defects.

[Effects of action and design]

The nozzle device according to the present invention has a nozzle main body 1 having a large diameter in the upper half and a small diameter in the lower half, and a first male for attaching a connecting pipe 3 to the outer periphery of a small diameter part 2 in the nozzle main body 1. Since the screw 4 is carved and the upper end of the inner diameter hole of the tube body 8 is made into a hexagonal hole 9 for fitting a hexagonal wrench, a connection having a female screw thread that can be freely engaged with the first male screw 4 on the inner circumferential surface of the upper end portion is made. If the pipes 3 are installed in advance at various places on the water pipe 19, they can be easily attached to the water pipe 19 by screwing, and they can be easily removed when replacing with a new one. This can be easily done by unscrewing. Also,
A tube body in which second male threads 6 are respectively carved on the outer periphery of the large diameter portion 5 of the nozzle main body 1, and an umbrella-shaped lid portion 7 is integrally connected around the opening edge at the upper end. 8, a first female thread 10 is formed on the inner peripheral surface near the upper end of the tube body 8, and a water guide hole 11 that communicates inside and outside is opened at a location near the lower end. When the second female screw 12 on the circumferential surface is screwed into the second male screw 6, the tube body 8 is inserted into the large diameter portion 5 and its lower end is fitted into the upper end opening of the narrow diameter portion 2. A closed cavity 13 is formed surrounded by the inner wall of the large diameter part 5, the lower surface of the lid part 7, and the outer wall of the tube body 8. Furthermore, in the lid part 7, a wall in contact with the cavity 13 is provided with an inclined wall that is open at both upper and lower ends. Separately from these, a water control piece 17 is constructed which has a driver groove 16 on the upper surface and a third male screw 15 carved on the outer peripheral surface of the upper half. 17 into the tube body 8 from above and tighten the third male screw 1.
5 and the first female screw 10, and the water control piece 17 is configured so that the water guide hole 11 is open when ascending and closed when descending, so the water flow adjustment operation is performed by fitting the tip of a screwdriver into the screwdriver groove 16. All you have to do is turn the water control piece 17. Furthermore, as mentioned above, the whole device consists of the nozzle main body 1, the tube body 8, and the water control piece 17, which are screwed together, so the structure is simple and suitable for miniaturization. It is something. Furthermore, as described above, each part can be assembled by screwing together, and disassembly can be done by unscrewing the screws, so cleaning or repair work can be done without extensive work. Thus, the nozzle device according to the present invention has the effect of completely achieving the intended purpose of providing a new nozzle device that solves all of the above-mentioned deficiencies.
