Description

[Technical Field]

[0001] The present invention relates to a bubble generating device for hydrogen baths that generates hydrogen gas bubbles in the bathwater in a bathtub, and more particularly to a bubble generating device for hydrogen baths that can be used in ordinary household bathrooms. [Background technology]

[0002] It has been reported that molecular hydrogen gas removes active oxygen and free radicals from living organisms, contributing to the promotion of health. Therefore, various devices using hydrogen gas for health and beauty purposes have been proposed. For example, devices have been proposed that blow hydrogen gas into the bathwater in a bathtub, exposing the bather to the resulting bubbles, or allow the bather to inhale hydrogen gas that has been degassed from the water surface, thereby providing various functions as well as relaxation and beauty benefits.

[0003] For example, Patent Document 1 discloses a device in which a hydrogen gas supply means consisting of a tubular object such as a pipe with holes for spraying hydrogen gas is submerged in the bathwater in a bathtub, hydrogen gas is supplied from a compressed hydrogen gas cylinder through piping to the hydrogen gas supply means, and hydrogen gas bubbles are sprayed into the bathwater in the bathtub. Here, the compressed hydrogen gas cylinder is installed in a fireproof storage room or the like outside the bathroom, and hydrogen gas is delivered into the bathtub through piping.

[0004] For general household use, compressed hydrogen gas cylinders are difficult to handle and have problems with their supply system. Therefore, devices that supply hydrogen through electrolysis have been proposed. However, because they require a power source, in household bathrooms that do not have electrical outlets for safety reasons, an external power supply must be secured or a battery must be installed, which also makes them difficult to handle.

[0005] Patent Document 2 discloses a hydrogen gas generator in which a case is filled with chemicals such as magnesium and calcium that react with water to generate hydrogen gas, and the case is submerged in a bathtub. The chemicals react with the water in the bathtub that has entered the case, and the hydrogen gas generated is released into the bathtub as bubbles from a hole in the top of the case. This device does not require a power source or complicated piping to generate hydrogen gas. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-36331 [Patent Document 2] Japanese Patent Application Publication No. 2017-225922 Summary of the Invention [Problem to be solved by the invention]

[0007] In the hydrogen gas generating device described above, which utilizes the reaction between bathwater water and chemicals, there is a risk that the chemicals may leak into the bathtub, and since the chemicals generate heat when reacting with water, care must be taken to prevent them from coming into contact with the bather. Therefore, a safer, simpler, and more compact device was desired.

[0008] The present invention was made in consideration of the above situation, and its purpose is to provide a compact hydrogen bubble generating device for hydrogen baths that does not require a driving power source, is easy to handle, and can be used in ordinary household bathrooms (bathtubs). [Means for solving the problem]

[0009] The bubble generating device according to the present invention is a bubble generating device for a hydrogen bath that adds hydrogen gas bubbles to the bathwater in the bathtub, and includes a resin container with a bottomed, cylindrical top opening that contains a chemical that reacts with water to generate hydrogen gas, along with water; a lid that can be freely opened and closed to seal the top opening of the resin container; a bubble generating unit made of a porous body that is submerged in the bathtub and releases the hydrogen gas that is sent out as bubbles into the bathwater; and a resin pipe attached to the lid that connects the bubble generating unit to the resin container.The device is characterized in that the internal pressure of the sealed resin container is increased by the hydrogen gas generated inside the resin container, and the hydrogen gas is sent to the bubble generating unit via the resin pipe.

[0010] According to these features, hydrogen bubbles for a hydrogen bath can be generated using a compact configuration that does not require a driving power source and is easy to handle, making it suitable for use in a general household bathroom (bathtub).

[0011] The above-described hydrogen bubble generating device according to the present invention may have the following additional features.

[0012] That is, the lid may be assembled so as to drop off from the resin container when the internal pressure reaches or exceeds a predetermined value.

[0013] The lid may be made of a flexible resin and may be fitted onto the inner periphery of the upper opening.

[0014] The apparatus may further include a pressure regulating valve provided near the lid or the upper portion of the resin container, which releases the hydrogen gas inside the resin container to the outside at a second predetermined value higher than the predetermined value.

[0015] Furthermore, the container may further include a pressing tool for placing the medicine at the bottom inside the resin container.

[0016] These additional features can further enhance the intended effects of the present invention, or can make the present invention more stable and convenient. [Brief explanation of the drawings]

[0017] [Figure 1] 1 is a schematic perspective view showing the configuration of a hydrogen bubble generating device for a hydrogen bath according to one embodiment of the present invention. [Figure 2] 2 is a schematic perspective view showing the agent and its container in the hydrogen bubble generating device of FIG. 1. FIG. [Figure 3] FIG. 10 is a schematic perspective view showing the configuration of a presser in a hydrogen bubble generating device for a hydrogen bath according to another embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, a hydrogen bath bubble generating device according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0019] FIG. 1 shows the configuration of an air bubble generating device according to an embodiment of the present invention.

[0020] In Fig. 1, bath water 100 made of hot water supplied for a hydrogen bath is stored in a bathtub 10. In this situation, a bubble generating set 2 is used as a bubble generating device according to this embodiment. The bubble generating set 2 generates, supplies, and diffuses a large amount of hydrogen gas bubbles 20 into the bath water 100 in the bathtub 10, bubbling the hydrogen into the bath water 100 and dissolving some of it.

[0021] The bubble generating set 2 is mainly composed of a resin container 3 , a lid 4 , a bubble generating unit 5 , and a resin pipe 6 .

[0022] The resin container 3 is formed in a cylindrical shape with a bottom and an upper opening 3u, and is capable of containing and storing a predetermined amount of water 3w to be poured into the container. A chemical container 30 that holds a chemical 3c (described later) is contained inside the resin container 3, and the entire chemical container 30 is submerged in the water 3w. In the containing portion of the resin container 3, the chemical 3c in the container 30 reacts with the water 3w to generate hydrogen gas 200.

[0023] The lid 4 has a shape that allows its bottom half to fit into the resin container 3 so as to seal the top opening 3u of the container, and is combined with the container so as to be able to open and close freely. The lid 4 is also made of resin, like the resin container 3, but is more flexible than the resin container 3 and is shaped so that it can be combined by fitting it into the inner periphery of the top opening 3u.

[0024] The bubble generating unit 5 has a main portion made of a porous body 5M, and the porous body 5M converts the hydrogen gas flow supplied to the inside of the porous body (not shown) into bubbles, generating numerous hydrogen bubbles that are then diffused and released into the bath water 100, creating bubbles. The bubble generating unit 5 is used by being submerged in the bath water 100 stored in the bathtub 10 and placed on the bottom of the bathtub 10. Therefore, the generated hydrogen bubbles travel a long distance from the bottom of the bath water 100 toward the top, allowing the hydrogen bubbles to remain and dissolve easily in the bath water 100.

[0025] The resin pipe 6 is attached to the lid 4 and connects the bubble-generating unit 5 with the inside of the resin container 3. More specifically, the resin pipe 6 allows hydrogen gas 200 generated in the resin container 3 and released from the lid 4 to pass through and flow into the intake port 5i of the bubble-generating unit 5. As a result, the hydrogen gas 200 flowing into the intake port 5i passes through the resin pipe 6 and flows into the porous body 5M of the bubble-generating unit 5.

[0026] In the above-described configuration, the hydrogen gas 200 generated inside the resin container 3 flows into the upper space of the sealed resin container 3, increasing its internal pressure, and enabling the hydrogen gas 200 to be sent to the bubble generating unit 5 via the resin piping 6. Based on this increase in internal pressure, the bubble generating unit 5 can release hydrogen bubbles for a hydrogen bath into the bath water 100, so the bubble generating set 2 can provide a hydrogen bath environment with a simple configuration, eliminating the need for a driving power source, etc.

[0027] The lid 4 is preferably designed to be assembled so that it will fall off from the resin container 3 when the internal pressure of the resin container 3 reaches or exceeds a predetermined value. This makes it possible to safely deal with abnormalities in the internal pressure of the resin container 3 due to some reason, including clogging of the porous body 5M. The predetermined value is set with safety in mind, but is also determined in relation to the pressure at which hydrogen gas is extruded from the porous body 5M.

[0028] In order to prevent the lid portion 4 from falling off from the resin container 3 due to internal pressure, it is preferable to use a structure that allows adjustment of the fitting strength on the inside of the periphery of the upper opening 3u, such as by attaching an O-ring to the outer periphery of the lid portion 4 or by providing a bellows portion made of a flange-shaped resin material.

[0029] 1, a pressure-regulating valve 7 may be provided on the lid 4, and the pressure-regulating valve 7 may be used to release the hydrogen gas 200 inside the resin container 3 to the outside, i.e., the piping 6, when the internal pressure of the resin container 3 reaches a second predetermined value higher than the above-mentioned predetermined value. The pressure-regulating valve 7 may be a rubber valve or a rubber stopper that falls off when the pressure reaches the second predetermined value. This allows the pressure inside the piping 6 to be kept constant, thereby achieving the effect of stably releasing hydrogen bubbles 20 into the bath water 100.

[0030] Although the embodiment in which the pressure adjustment valve 7 is provided in the lid 4 has been described here, it is also possible to provide such a pressure adjustment valve near the top of the resin container 3. Furthermore, such a pressure adjustment function may be provided in the internal structure of the lid 4. Either of these embodiments may be selected depending on the shape of the lid 4 and the design specifications of other parts.

[0031] 1, it is preferable that the chemical container 30 be fixed to the bottom of the resin container 3 so that the chemical 3c can be continuously submerged deep in water. For this reason, a fitting portion 3b is formed on the inner bottom surface of the resin container 3, and this fitting portion 3b fits into the bottom of the chemical container 30 to fix the chemical container 30 to the bottom surface of the resin container 3. In this way, in this embodiment, the chemical container 30 and the fitting portion 3b form a holder that positions the chemical 3c at the inner bottom of the resin container 3. This ensures stable generation of hydrogen gas.

[0032] FIG. 2 shows the medication 3c and its container 30 in the bubble-generating set 2 of FIG.

[0033] 2, the drug container 30 comprises a lower cage 31 that contains drug 3c, and an upper cover 32 that is screwed onto the top of the cage 31 and covers the top of the cage. As shown in Fig. 2, the cage 31 is formed with a large number of roughly rectangular openings that expose the inside of the cage, arranged vertically and horizontally, and has a structure that allows drug 3c placed inside the cage to easily react with water that enters through these openings.

[0034] When the hydrogen bubble generating set 2 is to be operated, the chemical 3c is placed in the cage 31, and the inner thread groove (not shown) of the cover 32 is rotated to align with the thread groove 31j and screwed together, closing the cage 31. Then, the chemical container 30 in this closed state is placed in the resin container 3, and then water 3w is poured into the resin container 3.

[0035] The chemical 3c is a hydrogen generating agent or catalyst made of materials such as magnesium, calcium, obsidian, tourmaline, antibacterial sand, weathered coral, etc. that reacts with water to generate hydrogen gas. When the chemical 3c is placed in the resin container 3 by the chemical container 30 and immersed in water 3w, it reacts with the water 3w to generate hydrogen, and gas 200 is released from the opening of the container 30.

[0036] In the above embodiment, the fitting portion 3b formed at the bottom of the resin container 3 is used as a device for holding down the drug 3c, but such a holding function may be realized by another method.

[0037] FIG. 3 shows the configuration of a presser in a hydrogen bubble generating device (hydrogen bubble generating set 2') for a hydrogen bath according to another embodiment of the present invention based on such a different technique.

[0038] In Figure 3, instead of the fitting portion 3b shown in Figure 1, a pressing rod 4r is provided at the bottom of the lid portion 4 and protrudes from the bottom. This rod 4r makes it possible to press the chemical container 30 toward the bottom of the resin container 3 when the lid portion 4 is fitted into the resin container 3. More specifically, during the fitting, the tip of the rod 4r abuts against the head cover 32 of the chemical container 30 and presses the cover 32 downward. This restricts the chemical container 30 from swinging up and down, and allows the chemical container 30 to be fixed or stabilized within the resin container 3. In particular, even if hydrogen accumulates inside the chemical container 30 and becomes buoyant, the hydrogen can be released to the outside.

[0039] According to the hydrogen bubble generating sets 2 and 2' of the above-described embodiments, hydrogen bubbles for hydrogen baths can be generated using a compact configuration that does not require a driving power source and is easy to handle and can be used in general household bathroom equipment.

[0040] The above describes the configurations of the embodiments of the present invention, but the present invention is not necessarily limited to these configurations, and a person skilled in the art can find various alternatives and modifications without departing from the spirit of the present invention or the scope of the appended claims.
