Description

[Detailed Description of the Invention] Technical Field This invention sprays an ultrasonic foam group into a bathtub,
This invention relates to a bubble vibrating bathtub for treating neuralgia, rheumatism, muscle pain, etc.

Conventional technology Conventionally, in a bubble vibrating bathtub, warm water in the bathtub is sucked in by a pump through an inlet provided on the bottom of the bathtub, and the inhaled hot water is passed through a foaming device installed on the inside surface of the bathtub. Since then, the same pump has been designed to eject it together with air, generating a group of ultrasonic bubbles.

However, these foamers are fixed to the inner surface of the bathtub, and their ejection direction is constant in the horizontal direction. Therefore, if you want to eject a group of bubbles toward the affected area, you can change the ejection direction of each foamer. There was the inconvenience of having to move the affected area according to the situation.

In order to solve this inconvenience, it has been proposed, for example, to install a variable nozzle on a foamer, as disclosed in Japanese Patent Laid-Open No. 143166/1983.

However, these conventional foamers have a problem in that the foamer cannot be easily disassembled at the time of failure or cleaning, and parts replacement, repair, cleaning, etc. cannot be easily performed.

Purpose This invention was made in order to eliminate the drawbacks of the conventional bubble vibrating bathtub foamer as described above, and its purpose is that it can be easily disassembled, parts can be easily replaced, and To provide a bubble vibrating bathtub foamer that can be repaired, cleaned, etc.
