Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an in-bath bubble generator that is used in a bathtub and sprays a stream of bubbles onto the body of a bather in the bath.

[Prior Art] Figures 2 to 5 show a conventional bath bubble generator A. In the figures, reference numeral 1 denotes a main body case consisting of a pair of front and rear casing members. Are they located at the top and left and right parts respectively? Gripping holes 1a are provided to form U number of gripping parts. As shown in FIG. 3, a sealed waterproof case 2 is housed inside the main body case, and inside this waterproof case 2 are a battery 3, a control circuit section 4,
and a motor 5 etc. are built-in. The rotary shaft 5a of the motor 5 projects liquid-tightly outside the waterproof case 2, and has an impeller 6 connected to its tip. This impeller 6 is housed in a pump casing 7 and constitutes a pump section that sucks water and generates a water flow.

Further, a cylindrical filter case 8 is connected to the suction side of the pump casing 7. The filter case 8 is made of a cylindrical member having a diameter substantially the same as the size of the pump chamber housing the impeller 6, and a filter support plate 9 and a filter 10 are housed inside the filter case 8. A water inlet 11 is opened on the bottom surface of the main body case 1 facing the lower end of the filter case 8, and this opening is closed with a filter cover 12 having a small hole for water passage. .

On the other hand, as shown in FIG. 4, the discharge port of the pump casing 7 communicates with a mounting portion 13 provided on the front surface of the main body case 1. In this attachment, a cylindrical air bubble outlet 14 is fitted to the part 13 so as to be movable together so that its direction can be changed arbitrarily, and this outlet 14 is screwed to the part 13. It is prevented from coming off by a nozzle cover 15.

Furthermore, an air suction port 16 is opened on the discharge port side of the pump casing 7, and constitutes a foaming section that generates bubbles with air taken in from the outside by the Venturi effect caused by the water flow from the pump section.

Further, an inner case tube 17 is connected to this suction port 16 . The case inner tube 17 is connected to one case outer tube via a joint 18, and a hollow spherical L-decoder 20 having an air intake port 20a is connected to the tip of the case inner tube 19. Incidentally, as shown in FIG. 20, a start switch 21 for operating the motor 5 is provided on the front surface of the main body case 1.

When using such bubble generation in bath @A,
As shown in FIG. 5, the bath WIB is immersed in hot water, but at this time, the hot water passes through the small hole of the filter cover 12 and enters the internal space between the main body case 1 and the waterproof case 2, thereby causing the bath to become hot. Since the buoyancy of the medium bubble generator A is reduced, the main body case 1 can be easily submerged in hot water.

Then, while the bath bubble generator A is submerged in the hot water of the bathtub B, the float 20 is placed floating on the scene. and,
It is used by turning on the start switch 21.

In other words, when the motor 5 is driven and the impeller 6 is rotated, a negative pressure is created in the pump casing 7, so hot water flows from the small hole of the filter cover 12 through the filter 10, the filter support, and the pump casing. 7 and sent to the discharge port of the pump casing 7 by the centrifugal force of the impeller 6. Since the water flow thus formed sucks air from the air suction port 16, air is taken in at the air suction port 20a of the float 20, and outside air enters the air suction port 16 via the inner and outer tubes 17 and 19. be guided. Therefore, air is continuously sucked in by the water flow, and as a result, water and air are mixed at the discharge port of the pump casing 7. In this way, bubbles are blown out into the bathtub B through the outlet 14. The bubble flow generated as described above can be sprayed toward the user.

[Problem to be solved by the invention] By the way, the float 2 in such a bath bubble generator A
0 floats above the hot water surface as shown in FIG. 5, and its air intake port 20a opens into the air above the hot water surface.

However, when a bather enters and exits the bath, or when the bather makes relatively large movements while bathing, the light float 20 shakes greatly due to fluctuations in the height of the bath water surface, ripples, etc., and may sink into the bath or cause the waves to In some cases, not only air but also hot water may be sucked in through the air intake port 20a.

As shown in Fig. 3, the inside of the float 20 is formed into a large hollow cavity in order to increase its buoyancy, so that the scale contained in the hot water sucked in through the air intake port 20a is removed from the float 20. It tends to adhere to the inner surface of the float 20 and accumulate.

During use, this accumulated scale peels off and floats in the bathtub near the face of the bathtub, and the odor of the scale becomes a concern.

Moreover, hot water enters the large inner space of the float 20, reducing its buoyancy and making it easier for hot water to enter.

The present invention was made in response to the above-mentioned problem, and its purpose is to provide a bath bubble generator that makes it difficult for scale and dry water to accumulate in the float.

[Means and effects for solving the problems] In order to solve the above problems, the present invention has a pump part that sucks in water and generates a water flow, and a pump part that sucks water and generates a water flow, and a venturi effect caused by the water flow from this pump part to take in air from the outside. A foaming section that generates air bubbles and sends out a bubble flow on the day of blowing is built into the main body case, and a long intake pipe that takes in air from the outside and is at least partially bendable is connected to this main case. The tip of the tube has an air intake port.
In an in-bath bubble generator to which a child is attached, a pipe portion communicating with an intake pipe and an air intake port is passed through the float, and the inner space of the float is sealed.

In this way, the pipe portion communicating with the intake pipe and the air intake port is passed through the float, and the inner cavity of the float is sealed, so that no scale is attached to the inner cavity of the float. In addition, since hot water does not enter the large inner space of the float, its buoyancy is always maintained.

[Example code] FIG. 1 shows an embodiment of the present invention.

In FIG. 1, reference numeral 32 denotes an intake pipe led out from the main body case l of the bath bubble generator A configured as described above.

This intake pipe 32 is communicated through an inner tube with a foaming section built into the main body case of the bath bubble generator as described above.

The intake pipe 32 is made of a flexible tube, and a float 33 is attached to the tip thereof.

The intake pipe 32 has its tip opening connected to the air intake port 32.
A, which allows more air to be taken in from the outside.

Further, the float 33 is made of a hollow spherical member, and the intake pipe 32 passes through the float 33. And float 33
Elastic rings 35 and 36 are inserted between the portion of the hollow spherical member through which the intake pipe 32 passes and the corresponding outer circumferential portion of the intake pipe 32 to seal the penetration portion. . As a result, the hollow interior side of the float 33 is liquid-tightly sealed. In addition, the tip end edge of the hollow spherical member of the float 33 is connected to the elastic ring 3 by a presser ring 37.
It is tightened to 5.

Further, hard reinforcing pipes 37 and 38 are fitted inside the intake pipe 32 corresponding to each of the sealing elastic rings 35 and 36, respectively. The reinforcing pipes 37 and 38 block the pressure exerted by the elastic rings 35 and 36 and the presser ring 37, thereby preventing the intake pipe 32 from being deformed.

Moreover, this enhances the sealing effect of the penetrating portion of the intake pipe 32.

Therefore, the float 33 provided at the tip of this intake pipe 32
The inner surface 33a is not exposed, and no scale is attached to this inner surface 33a.

In other words, when a bather enters and exits the bath, or when he or she makes relatively large movements in the bath, the light float 33 may sway due to fluctuations in the height of the bath or ripples, causing it to sink into the bath.
Even if there is a chance that not only air but also hot water may be sucked in from the air intake port 32a due to waves, the hot water will flow only through the intake pipe 32, which has the same diameter over the entire length, and the large hollow part of the float 33 Hot water does not enter the space.

Therefore, the large hollow inner surface 33a of the float 33 is prevented from being deposited with scale.

Therefore, it is possible to prevent the scale from being broken during use and floating in the bathtub near the famous author's face, or from being bothered by the odor of the scale.

Further, since hot water does not enter the relatively large inner space of the float 33, the buoyancy of the float 33 is always ensured, and hot water can be further prevented from entering.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications are possible. for example,
The intake pipe may not be made of a flexible tube over its entire length, but may have a proximal end portion that is bendable and a distal end portion that is made of a hard pipe member. The latch is inserted into the hard pipe member. If this hard pipe member is used, it is not necessary to use the reinforcing pipe as described above. A bellows, a spiral tube, or the like can be used as the bent portion.

[Effects of the Invention] As explained below, according to the present invention, the tip pipe portion penetrates the float and directly communicates the intake pipe with the air intake port, and also seals the inner space of the float. ? No hot water builds up on the inner surface of the child's wide internal space. Furthermore, since hot water does not enter the large inner cavity of the float, the buoyancy of the float is always ensured.
