Operation With the above-described configuration, an annular water jet is formed so as to surround the outlet of the air suction pipe, and water is jetted in a cylindrical shape from around the water jet, so that the water is surrounded by the water jet. A very strong negative pressure is generated in the part where the air intake pipe is located, and the pressure difference between the inlet and the outlet of the air suction pipe becomes very large. Air is taken in and is ejected with water.

Hereinafter, the operation will be described. When water is jetted from the annular water jet 13, the air pressure at the outlet of the air suction pipe 10 surrounded by the water jet 13 is in a negative pressure state as compared with the outside. In other words, the water is ejected in a cylindrical shape from around the outlet of the air intake pipe 10, and the speed immediately after the water is ejected is very fast. A large amount of air at the 10 outlets will be conveyed. Therefore, the pressure in the portion surrounded by the water jet 13 is greatly reduced, and the pressure difference with the outside is increased.
Due to the pressure difference, a large amount of air is taken in from the outside via the air suction pipe 10, mixed with water spouted from the water spout 13, and spouted into the bathtub 1 from the spout 15 of the venturi 7. The following table shows the measured values of the air intake amount in this embodiment together with the measured values in the case of the conventional example in FIG. 4 measured under the same conditions.

Advantageous Effects of the Invention As described above, the present invention arranges an air suction pipe inside a nozzle section for jetting water, and arranges a tip end of the air suction pipe coaxially with an ejection port section of the nozzle section, An annular water jet is formed around the outlet of the air suction pipe,
Since water is spouted from the water spout in a cylindrical shape, a very strong negative pressure is generated in a portion surrounded by the water spout,
The pressure difference between the inlet and the outlet of the air suction pipe becomes very large, so that a large amount of air is taken in. Therefore, it is possible to mix more air without reducing the amount of water jetted.
