In, when water is pushed out from the nozzle port 12 by air pressure,
For example, as shown in FIG. 3, when the water mass 2 is completely pushed out of the nozzle port 12, the air comes out of the nozzle port 12 and expands rapidly. And with the rapid expansion of such air,
A loud noise may be generated, or water may be formed into water droplets or mist, and may scatter vigorously (reference numeral 3 indicates a scattered area).

を目的とする。The present invention has been made in view of the above problems, and has been devised so as to absorb water droplets and mist generated by the rapid expansion of expanded air or air immediately after exiting from a nozzle port, and also sound. By doing so, it is possible to see a place where a beautifully shaped body of water jumps out into the air, and not to give a viewer an unpleasant sensation due to sound generation.

口と同心状に配備されているものである。The pneumatic nozzle according to the present invention is provided at a nozzle port through which water is extruded by air pressure, and a perforated cylinder having a diameter larger than the diameter of the nozzle port and disposed outside the perforated cylinder. A cylindrical body having the sound absorbing layer provided and an outer cylinder surrounding the outer surface of the sound absorbing layer is provided concentrically with the nozzle port in a state of protruding from the nozzle port.

止すると同時に、遮音を行うことにも役立つ。With this configuration, when air comes out of the nozzle port and expands rapidly when the water mass is completely pushed out of the nozzle port, the air passes through the hole of the perforated cylindrical body. The expansion of the air is reduced, and water droplets and mist generated by the expansion of the air are separated from the air. The sound generated by the rapid expansion of the air is not only absorbed by the sound absorbing layer, but also the reflection of the air expanded by the sound absorbing layer is suppressed. Further, the outer cylinder prevents air from leaking to the surroundings, and at the same time helps to provide sound insulation.

And an outer cylinder 8 surrounding the outer cylinder. A large number of air vents 82 having small holes are formed in the upper plate 81 of the outer cylinder 8 as shown in FIG. 2, while a drain vent hole 84 is formed in the bottom plate 83 of the outer cylinder 8. . Reference numeral 85 denotes an opening formed at the center of the upper plate 81 of the outer cylinder 8.

確認している。In the pneumatic nozzle 1 having the above structure, when water accumulated in the nozzle tube 11 or the water supply passage leading to the nozzle tube 11 is pushed out vigorously from the nozzle port 12 by air pressure, a water mass comes out from the nozzle port 12. Immediately after that, the air is discharged from the nozzle port 12 while rapidly expanding. The discharged air passes through the small holes of the perforated cylindrical body 6 or acts as a baffle of the perforated cylindrical body 6, so that the expansion momentum is reduced, and the sound absorbing layer 7 absorbs the air momentum. As a result, reflection in the cylinder is less likely to occur. The air that has passed through the perforated cylinder 6 is prevented from leaking in the outer peripheral direction by the outer cylinder 8, and is quickly discharged from the air vent hole 82 of the upper plate 81. For this reason, not only generation of the sound accompanying the rapid expansion of the air is suppressed, but also the generated sound is absorbed by the sound absorbing layer 7. Further, since the outer cylinder 8 is useful for sound insulation, the sound insulation effect makes it difficult for the sound to be heard outside. On the other hand, water droplets and mist generated due to the expansion of the air are separated from the air by the action of the perforated cylinder 6, accumulate at the bottom of the outer cylinder 5, and are discharged from the drain hole 84 of the bottom plate 83. It has been confirmed that these effects are more remarkably exhibited as the ratio D / d between the inner diameter D of the outer cylinder 8 and the inner diameter d of the perforated cylindrical body 6 increases.

え、音の発生による不快感を生じることもない。When the water mass is pushed out from the nozzle port 12 by the air pressure nozzle 1 by air pressure, the water mass emerges from the nozzle port 12 and then passes through the opening 85 and jumps out into the air. Then, when the water mass is viewed from the outside, only a clean water mass appears to come out from the nozzle port 12 or the opening 85, and there is no discomfort due to generation of sound.

It is also possible to use a perforated cylinder having a corrugated cylinder wall, a perforated cylinder having irregularities formed on the cylinder wall, or a perforated cylinder having a large number of folds. For the sound absorbing layer 7, a material exhibiting a sound absorbing function such as a porous material or a fiber assembly is used.
A gap may or may not be provided between the and the perforated cylindrical body 6.

なくなるという効果がある。[Effect of the Invention] As described above, according to the pneumatic nozzle of the present invention, even if the air that has pushed out the water mass from the nozzle opening expands suddenly and generates sound, or the sudden expansion of the air causes water droplets and fog. Even if air bubbles occur, only the clean water mass from the outside can be removed from the nozzle port by the action of reducing the air expansion by the cylindrical body, separating water droplets and fog from the air, absorbing sound, insulating sound, and preventing air leakage. This makes it appear that the sound is coming out of the room, and has the effect that no discomfort due to the generation of sound is caused.
