Description

TECHNICAL FIELD The present invention relates to an improvement of a bubble massager used in bathtub water.

[Conventional technology]

As a conventional example of a bubble massager, JP-A-59-1604
The invention described in Japanese Patent No. 57 can be mentioned.

And according to the bubble massager described in the above publication,
The filter provided facing the pump water inlet can be easily attached and detached.

Further, the bubble massager described in the above publication is to be used by attaching the massager to the wall of the bathtub or completely submerging it in water.

[Problems to be Solved by the Invention]

By the way, when using the bubble massager attached to the wall surface of the bathtub, each user needs to move his / her body in a narrow bathtub in order to adjust the local portion to be massaged to the bubble massager, but in the case described later, That is, it is not necessary to manually operate the bubble massager submerged in the bathtub water toward the local area to be massaged, unlike the case where the bubble massager is used while being submerged in the bathtub.

However, according to the above-mentioned publicly known example, when a bubble massager containing a heavy load such as a pump drive motor or a storage battery is attached to the wall surface of the bathtub via a suction cup and used, the suction cup fixed to the wall surface of the bathtub may deteriorate over time. , At a relatively early stage, the suction cup cannot withstand the weight of the bubble massager so that it cannot be used, and the suction cup replacement cycle becomes shorter.

On the other hand, when using the bubble massager submerged in the bathtub, each user has to adjust the local area to be massaged to the bubble massager like when using the bubble massager attached to the wall surface of the bathtub. In addition, you don't have to move your body in a narrow bathtub.

However, according to the above-mentioned publicly known example, when the bubble massager submerged in the bathtub water is directed to the portion to be massaged, the bubble massager, which is a heavy weight sinking at the bottom of the bathtub water, must be moved one by one. .

Further, according to the above-mentioned publicly known example, when the bubble massager is used in a state of being completely submerged in the bathtub water, the intake pipe for introducing air into the jet flow of the pump to generate bubbles is always connected to the atmosphere. In order to pass through, this intake pipe requires a complicated structure in which it is formed by a plurality of pipes having different diameters and is expanded and contracted.

An object of the present invention is to, when using a bubble massager attached to a bathtub wall surface, make it possible to prolong a replacement cycle due to aged deterioration of a suction cup attached to the bathtub wall face, and to move the bubble massager. An object of the present invention is to provide an improved bubble massager which, when used, has good handleability, has a simple structure, and keeps the overall size of the device large.

[Means for Solving the Problems]

The above-mentioned purpose is located above the pump body case in the bubble massager, and is vertically arranged with the board surface portion of the control circuit board, which is a light-weight component sealed with water from the outside, being vertical,
In addition to providing a closed air chamber that gives buoyancy to make the massager portable in the bathtub water,
Located in the lower part of the pump body case, a heavy battery such as a storage battery and a pump drive motor are respectively installed in a water seal, and by the buoyancy acting above the pump body case floating in the bath water and the gravity acting below, This is achieved by configuring the massage machine to be an inverted shape that does not invert or fall sideways in water.

[Action]

Thus, according to the present invention having the above-mentioned structure, a seal is provided above the pump body case to provide buoyancy so that the bubble massager can be carried in a state of being suspended in the bath water by being water-sealed with the outside. By providing the air chamber, buoyancy acts above the bubble massager in the bathtub water, and when the massager is attached to the wall surface of the bathtub and used, the weight of the bubble massager in water is reduced.

Further, according to the present invention, when the bubble massager is used by moving it toward a local portion to be massaged without moving the body in a narrow bathtub, the closed air chamber, that is, the water in the bubble massager by buoyancy is used. In connection with the weight reduction in the pump body, the storage battery and the pump drive motor, which are heavy parts, are installed in the lower part of the pump body case, respectively, and are installed above the pump body case that is floating in the bath water. Due to the buoyancy that works and the gravity that works downwards, the massage machine is configured to be an inverted shape that does not invert or fall sideways in water, so that each user can touch the part of the bubble massage machine lightly. The machine can be moved smoothly.

〔Example〕

Hereinafter, the present invention will be described with reference to an embodiment of the drawings. FIG. 1 is a longitudinal sectional view showing the entire structure, FIG. 2 is a left side view of a part of the longitudinal section of FIG. 1, and FIG. FIG. 4 is a cross-sectional view taken along the line AA of FIG. 1, and FIG. 4 is a view showing an example of use when the bubble massager is installed in the bathtub.

1 to 3, front case 1-1 and rear case 1
-2, and further, an inner case 4 is provided in the pump body case 1 composed of the storage battery cap 1-3, and the inner case 4 is water-sealed in two stages vertically by a lead wire packing 2. The chambers 13 and 26 are formed. The storage battery 5 is housed in the lower chamber 26, and the inside of the storage battery housing chamber 26 is sealed by the storage battery cover 7 via the rubber packing 6. A control circuit board 8 is provided in the chamber 13 above the inner case 4,
The opening of the chamber 13 is hermetically sealed in a water-tight manner by the circuit cover 11 having the terminals 9 and 10 for charging the storage battery 5 through the rubber packing 12, and thus the chamber 13 is closed. Thus forming a closed air chamber.
Reference numeral 15 denotes a motor case in which the pump drive motor 14 is housed. The inside of the motor case 15 is sealed by the lead wire packing 3. An impeller 17 rotated by a pump drive motor 14 is attached to the lower part of the motor case 15 via an oil seal 16. The impeller 17 and the pump cover 19 provided with a filter 18 allow the vortex to move. A winding pump unit 20 is formed. A lower end of an intake pipe 22 that introduces air from the outside is connected to the fluid ejection port 21 of the pump portion 20, and an upper end of the intake pipe 22 is connected to an intake joint 23 of the pump body case 1. . On the other hand, the pump body case 1 is provided with a push button 25 having a built-in magnet 24, and a reed switch (not shown) provided in the air chamber 13.
ON-OFF.

As shown in FIG. 4, the bubble pine surge machine moves the pump body case 1 to the wall surface of the bathtub 27 via the suction cup 28, or while the user holds it in the hand and floats it on water. Push button 2
When 5 is pressed, the magnet 24 closes the reed switch, the pump drive motor 14 supplied with electric power from the storage battery 5 rotates, and the impeller 17 absorbs water. It gushes out from 21,
At this time, the jet flow from the pump unit 20 causes the intake pipe 22
A pine surge effect is obtained by inhaling air from the body and applying the bubble flow thus generated to the body of the bather.

Naturally, the storage battery 5 can be charged, but when it is replaced with a new storage battery due to its life, the battery cap 1-3 and the storage battery cover 7 are removed and the storage battery 5 is replaced.

Since the buoyancy of an object is equal to the weight of the volume of water increased when the object is submerged in water, the volume of the control circuit board housing chamber (closed air chamber) 13 can be increased in the case of the present invention. The higher the buoyancy, the greater the buoyancy, but as shown in FIG. 3, by vertically arranging the control circuit board 8 in the closed air chamber 13 with the board surface portion of the control circuit board 8 vertical, a thin structure of the bubble massager as a whole can be obtained. The buoyancy that is required is obtained while aiming at the improvement, and according to this configuration, the flat ratio occupied by the bubble massager in the narrow bathtub 27 is minimized so that the bather can keep the bathtub in the bathtub 27. You can increase the margin that can be moved by.

As shown in the illustrated embodiment, the control circuit board housing chamber 1
By integrally molding 3 and the storage battery accommodating chamber 26, it is not necessary to separately assemble the chambers 13 and 26 into the pump body case 1, which contributes to a reduction in the number of parts and a reduction in the number of assembly steps.

〔The invention's effect〕

According to the present invention, (1) a closed air chamber 13 which is located above the inside of the pump body case 1 and which is buoyant so that it can be carried in a state where it is water-sealed with the outside and the bubble massager is suspended in the bath water. By providing buoyancy above the bubble massager in the bathtub water, when using the massager attached to the wall surface of the bathtub, the weight of the bubble massager in water is reduced,
Therefore, the weight load of the suction cup 28 attached to the wall surface of the bathtub can be reduced, and the replacement cycle due to deterioration of the suction cup 28 over time can be extended.

For example, the width of the bubble massager is 240mm and the depth is 75mm.
mm, the height is 260 mm, the weight is about 3 kg, and the buoyancy is originally 1 kg, the weight of this bubble massager in water is about 2 kg, but the control circuit board 8 is provided. If the volume of the closed air chamber 13 is about 1000 cm ³ , the weight of the bubble massager in water is reduced to about 1 kg.

In addition, according to the present invention, (2) when the bubble massager is moved toward the local area where the massage is desired without moving the body in the narrow bathtub 27, the closed air chamber 13, that is, In association with the reduction of the weight of the bubble massager in water due to buoyancy, the storage battery 5 and the pump drive motor 14, which are heavy parts, are respectively placed under the pump body case 1 in a water-sealed state, and placed in the bath water. Due to the buoyancy acting above the pump body case 1 in the floating state and the gravity acting below, the massage machine is configured to be an inverted shape that does not invert or fall sideways in water. The massager can be moved smoothly just by touching the part, and even if the bubble massager suddenly stands upside down or falls sideways during use. rather than,
It can be handled very well and eliminates the hassle of having to move a heavy bubble massager one by one, as in the past when the bubble massager is used while it is completely submerged in the bathtub. You can

Further, (3) the bubble massager is used in a state of being completely submerged in the bathtub, as in the above-mentioned publicly known example, air is always introduced into the jet flow of the pump to generate air bubbles between the intake pipe and the atmosphere. In order to communicate with each other, a complicated structure in which an intake pipe is formed by a plurality of pipes having different diameters and is expanded and contracted is not required.

In addition to this, according to the present invention, (4) since the board surface portion of the control circuit board 8 is vertically arranged in the closed air chamber 13 for generating buoyancy,
This is to obtain the necessary buoyancy while reducing the thickness of the bubble massager as a whole, and according to this configuration, the planar ratio occupied by the bubble massager in the narrow bathtub 27 is minimized. Therefore, the margin in which the bather can move in the bathtub 27 can be increased accordingly.
