[Conventional technology]

The conventional bubble massager was developed in 1987-387.
As described in Publication No. 5, this is a bath massage machine that generates a jet of bubbles underwater to obtain a massage effect, but if you want to apply it to the extreme parts of your body, you have to move your body closer to the jet opening. The configuration was such that the main unit was brought close to the body.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not take into account the point that the bubble jet can be freely applied to the desired place or close to the extreme part of the body, and there is a problem that it is difficult to handle the bubble jet in order to effectively apply the bubble jet to the body. there were.

The purpose of the present invention is to make it possible to freely and effectively generate a powerful bubble jet close to the desired place or extreme part of the body, even if the body moves away from the main body, and to improve ease of use, ease of handling, and massage effect. Our goal is to provide a hose for bubble massagers that allows you to improve your air bubble massager.

[Means to solve the problem]

In order to achieve the above object, the present invention is capable of generating a powerful bubble jet by mixing water and air at the discharge port of a bubble massager hose connected to a bubble jet port of a bubble massager main body. . Furthermore, to improve handling and performance, the case and curved spout tube were connected so that the ejector could rotate inside, and the axis of the ejector was aligned with the axis of the curved tube inlet. Furthermore, as a measure to improve performance, the cross-sectional area of the bent jet pipe was made larger than the opening area of the ejector's diffuser. In order to improve handling, a removable suction cup was also installed to allow rotation relative to the case.

However, if the bubble massager hose of the present invention is not required, in order to be easily attached and detached from the bubble massager main body, the structure is such that the direction variable nozzle of the main body and the intake port of the bubble massager hose are simultaneously connected,
Due to its structure, losses such as water leakage and pressure loss can be reduced.

[Effect]

By providing an intake ejector at the bubble jet outlet of the bubble massager hose that is detachable from the bubble massager main body, even when the body is far away from the main body, the bubble massager hose can be connected to the bubble jet port of the main body. A powerful bubble jet can be generated effectively and freely by bringing the bubble jet close to a desired place or extreme part of the body. Furthermore, by connecting the case and the bent ejection pipe so that the ejector can rotate inside, the hose for the bubble massager does not bend and is easy to handle when used. Furthermore, by aligning the axis of the ejector with the axis of the inlet of the bent pipe, performance becomes constant regardless of the direction of the bent pipe. Further, by making the water flow cross-sectional area of the curved jet pipe larger than the diffuser opening area of the ejector, the curved jet pipe brings out the diffuser effect and improves intake performance. In addition, by providing a removable suction cup on the case of the bubble massager hose and making it rotatable relative to the case, the bubble massager hose can be fixed to the inner wall of the bathtub, making it easier to handle.

Furthermore, by adopting a structure in which the variable direction nozzle of the main body and the suction port of the air bubble massager hose are combined at the same time, it can be attached to and removed from the main body with one touch, and the area of the joint part is larger than the opening area of the variable direction nozzle of the main body. This not only provides guidance when attaching and detaching the bubble massager hose, but also reduces water leakage due to the suction action of the nozzle's dynamic pressure.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

First, the main body structure on which the present invention is based is shown in FIGS. 1 to 3. A main body case 3 consisting of a front case 1 and a rear case 2 includes a battery case 5 housing a battery 4, a rotating cover 8 housing a control circuit 6 and having a terminal 7 for charging the battery 4, and a pump motor 9. The motor cases 10 containing the motors are water-sealed and hermetically sealed to each other via rubber packings 11. The lower part of the motor case 10 is water-sealed by an oil seal 12, and an impeller 13 rotated by the pump motor 9 is provided, and together with the pump power bar 14, a spiral pump part is formed.
