Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a connection structure between a blower disk and a bathtub, and more particularly to a technique for preventing damage to the connection point.

[Background Art] Conventionally, in the connection structure between a blower panel and a bathtub, as shown in FIG. The air inlet 2 of the blower plate 1 is connected to the air outlet member 6, but if the attachment position of the air outlet member 6 to the bathtub 5 is shifted, the weight of the person riding on the blower plate 1 during bathing will be transferred to the air outlet member 6 and There was a problem in that a concentrated load was applied to the air inlet 2 portion of the blower disk 1, causing damage to these weak points. In addition, if the height of the air inlet 2 on the blower plate 1 side changes due to wear and tear of the leg rubber 22 attached to the blower plate 1 side, a concentrated load will be applied to the above connection point, resulting in damage and long-term damage. The problem was that it was difficult to use for many years.

[Purpose of the invention] The present invention was created in view of these problems, and its purpose is to absorb misalignment on both the bathtub side and the blowhole side, and to prevent damage to the connection points. The purpose is to provide a connection structure between the blowhole and the bathtub.

[Disclosure of the invention] The connection structure between a blower disk and a bathtub according to the present invention is such that the angle between the air inlet 2 of the blower disk 1 that spews out air bubbles and the air supply port 3 on the bathtub 5 side can be freely changed via a ball joint 4. It is characterized by being connected, and by configuring it in this way, the above object is achieved. In other words, by connecting the air inlet 2 of the blow disk 1 and the air inlet 3 on the bathtub 5 side via the ball joint 4 so that the angle can be freely changed, the position of the air inlet 3 and the air inlet 2 can be adjusted. In particular, it can also cope with fluctuations in the height of the air supply port 3 due to wear of the leg rubber 22 due to use, and in this way, it can absorb positional deviations during construction and during use. However, it is possible to eliminate concentrated loads from being applied to the connection points, allowing stable use over a long period of time.

Embodiments of the present invention will be described in detail below based on the drawings.

As shown in FIGS. 1 and 2, a blow disk 1 that spews out air bubbles is submerged in the bottom of a bathtub 5, and a switch S
Activate the air pump P by operating the pipe 7.
Pressurized air is introduced into the blowhole 1 through the blowhole 1, and the introduced air passes through a porous plate 8 in the blowhole 1 and can be ejected as bubbles from the blowhole 9 to the upper side of the bathtub 5. . A check valve 10 is installed in the pipe 7.
is provided to prevent the hot water in the bathtub 5 from flowing back to the air pump P side.

FIG. 3 shows the connection structure between the blower panel 1 and the bathtub 5. Through hole 12 in stepped portion 11 at the bottom of bathtub 5
An air outlet member 6 having an air supply port 3 formed therein is inserted thereinto and connected to a pipe 7 by screwing. A spherical portion 13 is formed around the air supply port 3, a groove 14 is formed in the spherical portion 13, and an O-ring 15 is fitted into the groove 14. One end side of a movable connecting member 16 constituting the ball joint 4 is inserted through an O-ring 15 so that the angle can be changed. Movable connection member 16
A spherical body portion 17 is also formed on the outer periphery of the other end. The maximum outer diameter of this spherical body part 17 is made larger than the through hole 19 of the inlet member 18 forming the air inlet 2 of the blower disk 1, and is screwed and connected to the lower case 20 of the blower disk 1. Inlet member 18
It is designed to prevent air from escaping from the air inlet 2. An O-ring 21 is interposed between the inlet member 18 and the spherical body part 17, and when the inlet member 18 is screwed in, the inner end of the movable connecting member 16 is pressed against the lower case 20. is integrated into the lower case 20. In such a case, the movable connecting member 16 is attached to the lower case 20 with its spherical body portion 17
It may also be configured to be movable by swinging at.
Thus, the air inlet 2 of the blower disk 1 that spews out air bubbles
and an air supply port 3 on the side of the bathtub 5 are connected via a ball joint 4 so that the angle can be changed freely.

In this way, the air inlet 2 of the blower panel 1 and the bathtub 5
By connecting the side air supply port 3 via a ball joint 4 so that the angle can be changed freely, the positional deviation of the air supply port 3 and the positional deviation of the air introduction port 2 can be absorbed. It is possible to cope with fluctuations in the height of the air supply port 3 due to wear of the air supply port 3. In this way, it absorbs positional deviations during construction and during use, eliminates concentrated loads on the connection points, and provides long-term maintenance. Can be used stably.

In addition, the structure of the ball joint 4 which connects the blow disk 1 to the bathtub 5 so that the angle can be changed can be changed in various designs.

[Effects of the invention] In short, the present invention connects the air inlet of the blower panel and the air supply port on the bathtub side via a ball-and-socket joint so that the angle can be changed freely. It can absorb positional deviations, and in particular, it can cope with fluctuations in the height of the air supply port due to wear of the leg rubber through use. It has the advantage that it can eliminate concentrated loads from being applied to the connection points and can be used stably over a long period of time.
