Description

[Technical Field]

[0001] The present invention relates to a hydrogen gas supply device for living organisms, and more particularly to a technology for stably supplying hydrogen mixed gas to living organisms in a hydrogen gas supply device for living organisms or a hydrogen gas inhaler for living organisms. [Background technology]

[0002] Inhaling hydrogen gas is considered to be a good way to neutralize excess active oxygen in the body and promote health, and various devices for inhaling such hydrogen gas have been developed. As a relatively easy method for generating hydrogen gas, a method of generating hydrogen gas by electrolysis has been adopted, and devices have been developed in which hydrogen gas generated from the cathode side is retained in a housing and supplied to the living body using a pump or the like.

[0003] However, because such conventional devices pump out all of the accumulated hydrogen gas, when an attempt is made to increase the supply volume, the hydrogen gas cannot be generated in time, and the concentration of the gas being supplied often changes significantly, resulting in a decline in supply quality. Therefore, there was a need for technology that could provide a stable supply of hydrogen gas regardless of the amount supplied to the living body.

[0004] To address these problems, various techniques have been proposed. For example, a hydrogen gas supply device for living organisms that can supply clean mixed gas to living organisms (see Patent Document 1) has been proposed and is a publicly known technique. More specifically, the device is configured such that water to be electrolyzed is introduced into a housing, which is composed of an anode chamber, a cathode chamber, and a diaphragm that separates the two chambers, a DC voltage is applied to electrodes sandwiching the diaphragm to generate hydrogen gas on the cathode side, and gas containing hydrogen gas that has accumulated in the upper part of the housing is pushed out by gas supplied from outside the housing, thereby supplying gas containing hydrogen.

[0005] However, with the proposed hydrogen gas supply device for living organisms, when an attempt is made to increase the supply amount of gas containing hydrogen gas, most of the hydrogen gas remaining in the housing is supplied in a short period of time, making it impossible to stably supply hydrogen-mixed gas, and the above-mentioned problems are not solved.

[0009] Furthermore, the present invention employs a means in which the diameter of the tip end portion of the diluent gas supply portion is smaller than the diameter of the base end portion.

[0010] Furthermore, the present invention employs a means in which the gas mixing section has a cover that covers the tip portion of the dilution gas supply section, and the gap between the tip portion of the dilution gas supply section and the cover forms a hydrogen gas inlet.

[0011] Furthermore, the present invention employs a means in which the electrolytic cell section is formed in a cylindrical shape with the anode inside.

[0014] Furthermore, the present invention employs a means for introducing ozone generated in the electrolytic cell section from above the ozone retention section and discharging it from an ozone discharge section located at the bottom of the ozone retention section. [Effects of the Invention]

[0015] The hydrogen gas supply device for living organisms according to the present invention can stabilize the amount of hydrogen gas contained in the hydrogen mixed gas regardless of the amount of hydrogen mixed gas supplied, thereby improving the quality of the hydrogen mixed gas during inhalation.

[0020] The components of the hydrogen gas supply device for living organisms 1 will be described with reference to FIGS. 1, 2, 3, and 6(b). The living body hydrogen gas supply device 1 is a device that allows living bodies to inhale gas containing hydrogen. It generates hydrogen gas by electrolysis, uses air as a diluent gas, and supplies a mixed gas of hydrogen gas and the diluent gas. The hydrogen gas supply device for living organisms 1 is broadly composed of an electrolytic cell 20, a hydrogen mixed gas generation section 50, and an ozone retention section 40. The hydrogen gas supply device for living organisms 1 is externally divided into a housing section 10 and a lid section 11. The lid section 11 can be removed from the housing section 10 to add raw electrolytic water 21 to the electrolytic cell 20, or to clean or perform maintenance on the electrolytic cell 20, etc. The lid section 11 also prevents hydrogen gas from dispersing into the air. The lid section 11 is equipped with a portion of the hydrogen mixed gas generation section 50. Power for the hydrogen gas supply device for living organisms 1 is obtained by connecting a DC 5V direct current power supply via a cable, for example.

[0021] The electrolytic cell 20 is a section where raw water for electrolysis is electrolyzed to generate and retain hydrogen gas. The electrolytic cell 20 forms a vessel for holding raw water for electrolysis 21, and is provided at its bottom with an electrolysis unit 30. The electrolytic cell 20 is provided at its top with a hydrogen retention section 22 for holding hydrogen gas produced by electrolysis. The hydrogen gas generated in the electrolysis unit 30 rises in the raw electrolysis water 21 as microbubbles and accumulates in the hydrogen accumulation section 22.

[0022] The electrolysis unit 30 is composed of a plurality of electrolytic cell sections 37. Each electrolytic cell section 37 is composed of a cathode 31, a cation exchange membrane 32, and an anode 33. The cathode 31 and the anode 33 sandwich the cation exchange membrane 32. The electrolysis unit 30 is formed by a plurality of cylindrical electrolytic cell sections 37 with the anodes inside. The axis of the cylindrical section is vertical. The electrolysis unit 30 is fixed by an electrode fixing part 34 in such a manner that the cylindrical bottom surface thereof contacts the bottom portion of the electrolytic cell 20. An anode-side water inlet 36 is disposed at the lower part of the peripheral surface of the electrolysis unit 30. For example, platinum-plated titanium wires woven into a diamond-shaped mesh are used for the negative electrode 31 and the positive electrode 33. The negative electrode 31 is connected to the negative side of a power supply by a cable (not shown), and the positive electrode 33 is connected to the positive side of the power supply by a cable (not shown). The cation exchange membrane 32 is a thin film having an ion exchange function that restricts the passage of ions. For example, "Nafion" manufactured by DuPont is used. In this case, the thickness is about 127 to 183 μm. Furthermore, an ozone outlet 35 that introduces ozone generated at the positive electrode 33 to the ozone retention section 40 is provided at the top of the electrolysis unit 30.

[0023] An auxiliary outside air intake section 24 is arranged in the hydrogen accumulation section 22 at the top of the electrolytic cell 20 to supplementarily take in outside air. The auxiliary outside air intake section 24 is a pipe structure that serves to supplementarily supply outside air to the hydrogen accumulation section 22 . The hydrogen in the hydrogen accumulation section 22 is sequentially taken in through the hydrogen gas inlet 72. If the amount of hydrogen taken in is the same as the amount of hydrogen generated, there is no need to take in outside air. However, if the amount of hydrogen taken in through the hydrogen gas inlet 72 is greater than the amount of hydrogen generated, the air pressure in the hydrogen accumulation section 22 drops, and the amount taken in through the hydrogen gas inlet 72 decreases. Therefore, by taking in outside air through the auxiliary outside air intake section 24, a drop in the air pressure in the hydrogen accumulation section 22 is prevented.

[0024] The auxiliary outside air intake 23, which is the outside air side opening of the auxiliary outside air intake section 24, is located at a position lower than the hydrogen accumulation section 22. More specifically, it is located at the same height as the bottom surface of the electrolytic cell 20. By positioning the auxiliary outside air intake 23 lower than the hydrogen accumulation section 22, even if hydrogen enters the auxiliary outside air intake section 24, it is possible to prevent the hydrogen from being uselessly released into the outside air.

[0025] The outside air inlet 25, which is the opening of the auxiliary outside air intake section 24 on the hydrogen accumulation section 22 side, is located lower than the hydrogen gas introduction port 72 and opens downward. By positioning the outside air inlet 25 lower than the hydrogen gas inlet 72, outside air can be taken in without affecting the hydrogen retained above the hydrogen retaining section 22. Furthermore, since the outside air inlet 25 opens downward, the taken-in outside air flows downward into the hydrogen accumulation section 22, thereby further reducing the impact on the hydrogen accumulated above the hydrogen accumulation section 22.

[0026] The hydrogen mixed gas generator 50 is a part that mixes the dilution gas with the hydrogen gas generated in the electrolytic cell 20. In this embodiment, it has a structure that penetrates the electrolytic cell 20 from top to bottom. With this structure, the gas flows linearly and the flow force is not restricted, allowing the hydrogen gas to flow in smoothly. The hydrogen mixed gas generating section 50 comprises a dilution gas supplying section 60, a gas mixing section 70, and a mixed gas discharging section 80.

[0027] The diluent gas supply unit 60 is a part that takes in the diluent gas and is cylindrical overall. In this embodiment, atmospheric air is used as the diluent gas. The diluent gas supply unit 60 is equipped with a fan 62 (hereinafter also referred to as a blower fan) at the diluent gas inlet 61, which can forcibly send the diluent gas into the diluent gas supply unit 60. Furthermore, by changing the output of the fan 62, the amount of diluent gas sent can be changed, and therefore the amount of hydrogen mixed gas output can be controlled. By positioning the fan 62 at a position lower than the electrolytic bath 20, the spread of noise such as the vibration sound of the fan 62 can be reduced by surrounding it with the housing 10 and the electrolytic bath 20. The fan 62 is related to the amount of mixed gas supplied, so a blower fan that can provide a strong blowing force is suitable.

[0028] The diluent gas supply section 60 is composed of a tapered circular pipe section 63 including a diluent gas inlet 61. The tapered circular pipe section 63 has a funnel-like shape that is thick at a base end 65 and gradually narrows in diameter toward a tip end 64. The end of the tapered circular pipe section 63 is inserted into the opening of the gas mixing section 70 with a gap therebetween.

[0029] The gas mixing unit 70 mixes hydrogen gas and diluent gas. The gas mixing unit 70 mixes the diluent gas sent from the diluent gas supply unit 60 with the hydrogen gas flowing in from the hydrogen gas inlet 72, and sends the mixture to the mixed gas outlet 80. The hydrogen gas inlet 72 is formed by the tip 64 of the tapered circular pipe portion 63 and the cover portion 71. The hydrogen gas inlet 72 faces the direction of the diluent gas inlet 61, which is the direction in which the diluent gas flows in. By opening in the direction in which the diluent gas flows in, hydrogen gas can be taken in from the hydrogen gas inlet 72 by utilizing the negative pressure generated by the flow of the diluent gas.

[0030] The hydrogen gas inlet 72 is disposed above the hydrogen accumulation section 22. Because hydrogen is lighter than air, hydrogen generated in the electrolysis unit 30 begins to accumulate above the hydrogen accumulation section 22. Therefore, hydrogen can be more efficiently taken in from the hydrogen gas inlet 72 when the hydrogen gas inlet 72 is disposed above the hydrogen accumulation section 22. "Above the hydrogen accumulation section 22" refers to a position higher than the midpoint of the hydrogen accumulation section 22 in the up-down direction. It is more preferable that the distance between the upper surface of the hydrogen accumulation section 22 and the hydrogen gas inlet 72 is smaller than the diameter of the hydrogen gas inlet 72. By making the distance between the upper surface of the hydrogen accumulation section 22 and the hydrogen gas inlet 72 smaller than the diameter of the hydrogen gas inlet 72, the portion with the highest hydrogen concentration can be taken in through the hydrogen gas inlet 72.

[0031] The mixed gas outlet 80 is the part that outputs the hydrogen mixed gas from the living body hydrogen gas supply device 1. One example is a method of connecting the end of a cannula 90 to the mixed gas outlet 81. The mixed gas outlet 81 is sized to easily connect the cannula 90. The mixed gas outlet 81 is rotatable, and the direction of the gas ejection can be changed arbitrarily.

[0032] The ozone retention section 40 is a section that temporarily retains the ozone generated by the electrolysis unit 30. The ozone retention section 40 is a container structure that holds gas, and includes activated carbon 41 that absorbs the odor of the retained ozone, and an ozone discharge section 42 that gradually discharges the gas with reduced odor. The ozone generated in the electrolysis unit 30 passes through the ozone outlet 35, is introduced into the ozone retention section 40 from above, and is retained therein. The odor of the ozone is reduced by activated carbon 41 in the ozone retention section 40, and the ozone is then discharged to the outside from an ozone discharge section 42 located at the bottom of the ozone retention section 40. Ozone is introduced from above the ozone retention section 40. Because ozone is heavier than air, the ozone naturally descends within the ozone retention section 40 and passes through the activated carbon 41, thereby efficiently reducing the ozone odor. Furthermore, since the ozone is discharged to the outside from the ozone discharge section 42 located on the bottom surface of the ozone retention section 40, ozone, which is heavier than air, is smoothly discharged from the ozone discharge section 42. The discharged ozone diffuses from the bottom surface of the hydrogen gas supply device 1 along the floor, making it difficult for users to sense the ozone odor.

[0033] The operation of the electrolysis unit 30 will be described with reference to FIG. The electrolysis unit 30 consists of two electrolytic cells 37, and a negative voltage and a positive voltage are applied to the negative electrode 31 and positive electrode 33 of each electrolytic cell, respectively. The voltage is approximately DC 8 to 10 V. The input power supply voltage of 5 V is boosted by a power supply circuit within the casing 10 and used to generate electrolysis. Hydrogen ions and electrons are generated on the positive electrode 33 side, pass through the cation exchange membrane 32, and become hydrogen gas at the negative electrode 31. The two electrolysis cells are cylindrical, with the positive electrode 33 on the inside and the negative electrode 31 on the outside. Therefore, ozone generated at the positive electrode 33 collects on the inside, and hydrogen generated at the negative electrode 31 collects on the outside, making it easy to separate the two gases. Furthermore, since a plurality of electrolytic cells can be used, gas can be generated more efficiently.

[0034] This hydrogen gas is formed as microbubbles, which are tiny bubbles, and gradually rises within the raw electrolytic water 21 and is collected in the hydrogen accumulation section 22. Furthermore, since the cation exchange membrane 32 is used, the ozone generated at the positive electrode 33 and the hydrogen generated at the negative electrode 31 do not mix, and hydrogen can be collected efficiently.

[0035] The generation of hydrogen mixed gas will be explained with reference to FIG. One conventional method involves pumping dilution gas into the hydrogen-collected region using an air pump or similar device, and then discharging the gas in the region as a hydrogen-mixed gas depending on the amount of gas pumped in. However, with this method, if the amount of gas discharged is increased, the entire gas in the region is discharged. If the amount discharged is continued to increase, the hydrogen gas content drops drastically, making it impossible to maintain a stable hydrogen gas content.

[0036] The diluent gas is supplied from the bottom side of the diluent gas supply unit 60 below the hydrogen mixed gas generation unit 50. A fan 62 is disposed on the bottom side of the diluent gas supply unit 60, so that a constant amount of diluent gas is supplied according to the output of the fan 62. By using a blower fan as the fan 62, a sufficient amount of air can be generated. Although the fan 62 can be provided at the outlet for the hydrogen mixed gas, this increases the size of the outlet to accommodate the fan 62, making it difficult to connect a cannula. The base end, which is the bottom side of the tapered circular pipe section 63, which is the inlet portion of the diluent gas supply section 60, has a large diameter, and the flow rate of the diluent gas is relatively slow. The tip end, which is the upper side of the tapered circular pipe section 63, has a conical shape with a smaller diameter, and the flow rate of the diluent gas is fast. The diluent gas, maintaining its high flow velocity, enters the gas mixing section 70. In the gas mixing section 70, a hydrogen gas inlet 72 formed by the tip 64 of the tapered circular pipe section 63 and the cover section 71 is provided so as to join the flow of the diluent gas.

[0037] The hydrogen gas inlet 72 faces the direction in which the dilution gas flows in. As a result, the hydrogen gas inlet 72 side is pulled relative to the main flow, generating negative pressure on the hydrogen gas inlet 72 side. Therefore, a portion of the hydrogen gas in the hydrogen accumulation section 22 enters the gas mixing section 70 through the hydrogen gas inlet 72, is mixed with the dilution gas, and the hydrogen mixed gas can be sent out from the mixed gas outlet 81 of the mixed gas outlet section 80. The flow rate of the diluted gas in the gas mixing section 70 is increased by the tapered tip of the tapered circular pipe section 63, so that hydrogen gas can be obtained from the hydrogen gas inlet 72 even if the flow rate is relatively slowed by the fan 62.

[0038] In this manner, in this embodiment, only a portion of the hydrogen gas in the hydrogen accumulation section 22 is mixed with the dilution gas, so even if the amount of the mixed gas to be delivered is increased, the amount of hydrogen gas in the hydrogen accumulation section 22 does not change drastically, and therefore a stable hydrogen gas content can be maintained.

[0039] The housing 10, lid 11, and hydrogen mixed gas generator 50 of the hydrogen gas supply device for living organisms 1 will be described with reference to FIG. 6(a). The living body hydrogen gas supply device 1 can be broadly divided into a housing 10 and a lid 11. The gas mixing section 70 and mixed gas outlet section 80 of the hydrogen mixed gas generator 50 are arranged in the lid 11. The dilution gas supply section 60 of the hydrogen mixed gas generator 50 is arranged on the housing 10 side. The hydrogen gas inlet 72 is formed by the cover 71 of the gas mixing section 70 and the tip 64 of the tapered circular pipe section 63, so the positional relationship of these parts is important.

[0040] If the cover 71 and the tip 64 are too close, the hydrogen gas inlet 72 will be blocked, making it impossible to take in hydrogen gas effectively. Also, if the distance between the cover 71 and the tip 64 is too large, the amount of negative pressure will decrease, making it impossible to take in hydrogen gas effectively. One method of defining the position is to place a spacer or the like between the cover 71 and the tip 64, but in this case the spacer will block part of the introduction of hydrogen gas. By providing the tip 64 on the housing 10 side and the cover 71 on the lid 11 side, the tip 64 and the cover 71 always have a constant positional relationship, and the hydrogen gas inlet 72 can be maintained. Therefore, there is no need to use spacers or the like, which is preferable.

[0041] As described above, the hydrogen gas supply device 1 for living organisms according to the present invention can stably supply hydrogen gas regardless of the supply amount of gas containing hydrogen gas, thereby improving the quality of inhalation. [Industrial Applicability]

[0042] The hydrogen gas supply device for living organisms according to the present invention is capable of stably supplying hydrogen mixed gas and also contributes to improving the quality of the gas when inhaled into living organisms. Therefore, it is believed that the hydrogen gas supply device for living organisms according to the present invention has great industrial applicability. [Explanation of symbols]
