Description

Hydrogen generator with suspended electrolysis module

The present invention relates to a hydrogen generator with a suspended electrolytic module, more specifically, to a hydrogen generator in which the electrolytic module is suspended in a water tank and connected to the upper cover of the water tank.

Human beings have always attached great importance to life, and many medical technologies have been developed to fight diseases and prolong human life. In the past, most medical treatments were passive, that is, when a disease occurred, symptomatic treatment was given, such as surgery, medication, or even chemotherapy and radiotherapy for cancer, or conditioning, rehabilitation, and correction of chronic diseases. However, in recent years, many medical experts have gradually moved towards preventive medical methods, such as research on health foods, genetic disease screening and early prevention, etc., which are proactive preventions for possible future diseases. In addition, in order to prolong human life, many anti-aging and antioxidant technologies have been gradually developed and widely adopted by the public, including applied skin care products and antioxidant foods/drugs.

Research has found that the unstable oxygen (O+), also known as free radicals (harmful free radicals), generated by the human body due to various reasons (such as disease, diet, environment or living habits) can be mixed with the inhaled hydrogen to form part of the water and excreted from the body. Indirectly reducing the number of free radicals entering the body, achieving the goal of reducing the acidic body to a healthy alkaline body, which can resist oxidation and aging, and thus eliminate chronic diseases and achieve beauty and health effects. In the way of increasing the amount of hydrogen inhaled, increasing the time of hydrogen inhalation (for example: using sleep time to inhale hydrogen) can also effectively enhance the efficacy of hydrogen inhalation.

Although inhaling hydrogen can achieve the above-mentioned effects and has many benefits for the human body, hydrogen is not readily available. Instead, it must rely on a special hydrogen generator to produce hydrogen for inhalation. Moreover, this type of hydrogen generator that provides hydrogen for human inhalation is different from the hydrogen generator used to produce hydrogen fuel for internal combustion engines. It must go through layers of filtration and sterilization to ensure that the hydrogen is pure and safe for human inhalation. This type of hydrogen generator that produces hydrogen for human inhalation generally uses a water electrolysis system as the main unit for producing hydrogen. The hydrogen produced by electrolysis is filtered multiple times through various filtering and disinfection methods to remove electrolytes or bacteria that are harmful to the human body. The humidity of the hydrogen is maintained or other atomized drugs or essential oils are added to produce hydrogen-containing gas suitable for human inhalation.

There is a hydrogen generator on the market, in which the electrolyzer is directly set and fixed in the water tank used to provide electrolyzed water, and the electrode can extend upward from the electrolyzer and be connected to the power supply through the cover of the water tank. In detail, the electrolyzer and the water tank can be fixed on the water tank body by means of screws, etc., so that the relative position of the electrolyzer and the water tank body is fixed. Therefore, the electrolyzer can directly obtain electrolyzed water from the water tank without pipeline connection and perform electrolysis to produce hydrogen-containing gas, and then output the hydrogen-containing gas to the water tank, and then output it from the water tank to the filtering and disinfection device of the hydrogen generator. In addition to facilitating the acquisition of water required for electrolysis, the electrolyzer can also be dissipated from the outside of the electrolyzer in the electrolyzed water of the water tank to improve the electrolysis efficiency.

The electrolyzer has electrodes inside that can electrolyze water to produce hydrogen-containing gas, which will directly enter the water tank and then be output to other units of the hydrogen generator. However, the hydrogen-containing gas produced by the electrolyzer will first accumulate in the upper part of the water tank space before being output, so pressure will accumulate inside the water tank. If the accumulated pressure reaches a certain level, the water tank needs to be depressurized to ensure that the water tank and even the entire hydrogen generator are not damaged. During the gas accumulation process, the lid of the water tank will be pushed up by the gas and slightly bulge and deform, and it will return to its original state when the pressure is released. Since the electrolyzer is fixed to the water tank, the bulging and recovery of the water tank cover during the above pressure accumulation and pressure release process will cause repeated relative displacement between the protruding electrode of the electrolyzer and the water tank cover. After the hydrogen generator has been used for a long time, there may be an irreversible offset between the electrode and the water tank cover, resulting in the risk of water and gas leakage.

Therefore, it is extremely necessary to develop a new type of hydrogen gas generator that can solve the above-mentioned problem of water and gas leakage caused by the accumulated pressure in the water tank to ensure the safety of users.

In view of this, one scope of the present invention is to provide a hydrogen generator with a suspended electrolysis module.

The condenser is vertically stacked on the humidifier and connected to one end of the connecting flow channel, and the other end of the connecting flow channel is connected to the water tank. The condenser receives hydrogen-containing gas from the water tank through the connecting flow channel.

The hydrogen generator further includes a hydrogen water cup connected to a humidifier, the hydrogen water cup is used to contain water, and receives hydrogen-containing gas from the humidifier into the water to generate and output hydrogen water.

Please refer to FIG. 1 and FIG. 2. FIG. 1 is a schematic diagram showing the internal structure of a hydrogen generator 1 with a suspended electrolysis module according to a specific embodiment of the present invention, and FIG. 2 is a schematic diagram showing a water tank 10 and an electrolysis module 12 of the hydrogen generator 1 of FIG. 1. As shown in FIG. 1 and FIG. 2, the hydrogen generator 1 with a suspended electrolysis module of the present specific embodiment includes a water tank 10 and an electrolysis module 12, wherein the electrolysis module 12 is located in the water tank 10, and the electrolysis module 12 can directly receive water in the water tank and perform electrolysis, and the hydrogen-containing gas generated by the electrolysis of water can enter the water tank 10. The hydrogen generator 1 can also include a condenser 14 and a humidifier 16, both of which can be vertically stacked on the water tank 10. The condenser 14 is connected to the water tank 10 to receive and condense the hydrogen-containing gas, and the humidifier 16 is connected to the condenser 14 to receive the hydrogen-containing gas after condensation by the condenser 14.

As shown in FIG2 , the water tank 10 includes a box body 100 and an upper cover 102. The box body 100 is recessed to form a receiving space 104 for receiving an electrolyte. In this specific embodiment, the electrolyte is water, and the upper cover 102 can cover the box body 100 and the receiving space 104. The electrolysis module 12 is disposed in the receiving space 104 of the box body 100. Therefore, the electrolysis module 12 can be directly immersed in the water contained in the receiving space 104, and directly obtain the water required for electrolysis from the receiving space 104, avoiding the connection of pipelines. The electrolysis module 12 includes an electrolysis housing 120 and a plurality of electrode plates disposed in the electrolysis housing 120. For the sake of simplicity, FIG2 only shows a portion of the anode plate 122 and a portion of the cathode plate 124 among the plurality of electrodes. In this specific embodiment, the plurality of electrode plates include an anode plate 122, a cathode plate 124, and a bipolar electrode plate therebetween. These electrode plates are arranged at intervals in the electrolysis housing 120, so that an electrode flow channel is formed between two adjacent electrode plates, and all electrode plates form a plurality of electrode flow channels parallel to each other to electrolyze water therein to generate hydrogen and oxygen, i.e., hydrogen-containing gas. The top of the electrolytic housing 120 has a plurality of upper openings 126 that can respectively connect the electrode flow channel and the upper half of the accommodating space 104. Correspondingly, the bottom of the electrolytic housing 120 also has a plurality of lower openings (not shown in FIG. 2 ) that connect the electrode flow channel and the lower half of the accommodating space 104. Through the upper openings 126 and the lower openings, the electrolytic housing 120 can receive water in the accommodating space 104 into the electrode flow channel for electrolysis, and output hydrogen-containing gas generated by electrolysis from the electrode flow channel to the accommodating space 104. Therefore, the electrolytic module of the hydrogen generator of the present invention, including its housing, is entirely located in the water tank, and the electrolytic module can be heat-dissipated through the water contained in the water tank. In practice, the hydrogen generator may include a cooling circulation system connected to the water tank storage space to circulate the cooling water in the storage space. At the same time, the electrolysis module and the water tank do not need to be connected through pipes to transmit water, so as to avoid the problem of water leakage and gas leakage caused by the deterioration of the pipes due to long-term use.

The anode plate 122 and the cathode plate 124 can extend outward from the electrolysis shell 120, as shown in FIG2. The extended portions of the anode plate 122 and the cathode plate 124 can be located in the holes of the upper cover 102 of the water tank 10, and can contact the power source in the holes to receive the power required for electrolysis. Please refer to FIG3, which is a schematic diagram of the upper cover 102 of FIG2 from another viewing angle. As shown in FIG3, the upper cover 102 has a hole 1020 on one side facing the accommodating space 104 to allow the anode plate 122 and the cathode plate 124 to be placed. The upper cover 102 also has a first fixing portion 1022 facing the accommodating space 104, and the first fixing portion 1022 includes two fixing rings respectively surrounding the circumference of the hole 1020, as shown in FIG3. In addition, the electrolytic housing 120 in FIG2 has a second fixing portion 128, and the second fixing portion 128 includes two rings respectively surrounding the circumference of the anode plate 122 and the cathode plate 124 extending therefrom. Therefore, when the electrolytic module 12 is disposed in the water tank 10, the anode plate 122 and the cathode plate 124 thereof can be located in the hole 1020, and the fixing ring of the first fixing portion 1022 around the hole 1020 and the ring of the second fixing portion 128 around the anode plate 122 or the cathode plate 124 are engaged with each other. Through the connection between the first fixing portion 1022 and the second fixing portion 128, the electrolytic module 102 can be connected to the upper cover 102 and interconnected therewith. In other words, the electrolytic module 102 is suspended in the accommodating space 104 of the water tank 10 through the upper cover 102.

In practice, when the electrolysis module 102 electrolyzes water to generate hydrogen-containing gas that enters the accommodating space 104 of the water tank 10, the hydrogen-containing gas will first accumulate at the top of the accommodating space 104 and be output upward to the condenser 14. During the gas accumulation process, the pressure in the water tank 10 increases and presses the upper cover 102 from the inside to make it slightly bulge and deform. Since the electrolysis module 102 is suspended from the upper cover 102 and linked to it, no matter how much the upper cover 102 bulges and deforms upward, through the connection between the fixing ring of the first fixing part 1022 and the ring of the second fixing part 128, the electrolysis module 102 and its anode plate 122 and cathode plate 124 maintain a consistent relative position with the upper cover 102. Similarly, when the electrolysis module 102 stops electrolysis or the water tank 102 is depressurized, the upper cover 102 returns to its original shape or position and links the electrolysis module 102 to maintain a consistent relative position with the upper cover 102. Since the electrolytic module 102 is linked with the change of the upper cover 102 to maintain the relative position, after long-term use, there will be no irreversible offset between the electrolytic module 102 and the upper cover 102, which will cause water leakage and gas leakage. In particular, the part of the anode plate 122 and the cathode plate 124 extending from the electrolytic shell 120 can be completely sealed in the hole 1020 of the upper cover 102, and there will be no risk of water vapor entering the hole 1020 and contacting the anode plate 122 and the cathode plate 124 due to position offset.

In this specific embodiment, the fixing ring of the first fixing part 1022 and the ring of the second fixing part 128 are connected to each other by hot melting, but the present invention is not limited to this. In practice, any fixing method that can stably connect the two and seal the part of the anode plate and the cathode plate extending from the electrolytic shell in the hole of the upper cover can be adopted by the hydrogen generator of the present invention.

Please refer to FIG. 2 again. As shown in FIG. 2, the upper cover 102 has a first positioning structure 1024 on one side facing the accommodating space 104, and the corresponding position on the electrolytic shell 120 of the electrolytic module 12 also has a second positioning structure 1200. The first positioning structure 1024 and the second positioning structure 1200 can be coupled to each other when the electrolytic module 12 is suspended on the upper cover 102, and the first positioning structure 1024 and the second positioning structure 1200 can maintain the freedom of moving up and down. In detail, the first positioning structure 1024 is a positioning hole, and the second positioning structure 1200 is a positioning column. When the electrolytic module 12 is suspended on the upper cover 102, the second positioning structure 1200 is located in the first positioning structure 1024 and can move up and down. By means of the first positioning structure 1024 and the second positioning structure 1200, the lateral deviation between the upper cover 102 and the electrolytic module 12 can be suppressed when the upper cover 102 is deformed due to the pressure accumulated in the water tank 10, so as to further suppress the leakage of water and air. As mentioned above, in the present specific embodiment, the two first positioning structures 1024 are positioning holes, and the two second positioning structures 1200 are positioning columns, but in practice, the two first positioning structures can also be positioning columns and the two second positioning structures can also be positioning holes, or the first positioning structure and the second positioning structure can each have a positioning column and a positioning hole, and the present invention is not limited to this. In addition, the first positioning structure 1024 and the second positioning structure 1200 of this specific embodiment are located on the sides of the anode plate 122, the cathode plate 124 and the hole 1020 of the upper cover 102, and there are two of them, but the present invention does not limit their number and position, depending on the needs of the user or designer.

On the other hand, please refer to FIG. 4 and FIG. 5 together. FIG. 4 is a schematic diagram showing the case 100 of the water tank 10 of FIG. 2 at another viewing angle, and FIG. 5 is a schematic diagram showing the electrolytic housing 120 of the electrolytic module 12 of FIG. 2 at another viewing angle. As shown in FIG. 4 and FIG. 5, the case 100 of the water tank 10 has a plurality of third positioning structures 1000 at the bottom of its accommodating space 104, and the electrolytic housing 120 forms a plurality of fourth positioning structures 1202 at its bottom, and these fourth positioning structures 1202 correspond to the third positioning structures 1000 on the case 100, respectively.

In this specific embodiment, when the electrolysis module 12 is disposed in the accommodation space 104 of the water tank 10 and suspended on the upper cover 102, the third positioning structure 1000 of the box body 100 of the water tank 10 is movably coupled with the corresponding fourth positioning structure 1202 of the electrolysis housing 120. In detail, the third positioning structure 1000 can be a positioning column, and the fourth positioning structure 1202 can be a tubular positioning column, so that the third positioning structure 1000 can be accommodated in the fourth positioning structure 1202, and because the third positioning structure 1000 and the fourth positioning structure 1202 are vertically extended, the third positioning structure 1000 can move up and down in the fourth positioning structure 1202, but cannot move sideways. When the electrolysis module 12 electrolyzes water to generate hydrogen gas that accumulates in the water tank 10, the upper cover 102 is slightly bulged and deformed due to the pressure from the accommodating space 104, thereby driving the electrolysis module 12 suspended on the upper cover 102 to move. Alternatively, when the electrolysis module 12 stops electrolysis or the water tank 10 is depressurized, the accumulated pressure in the water tank 10 disappears, causing the upper cover 102 to return to its original state, and at the same time, driving the suspended electrolysis module 12 to move. By means of the third positioning structure 1000 of the box body 100 and the fourth positioning structure 1202 of the electrolysis housing 120, the relative movement direction between the electrolysis module 12 and the box body 100 can be limited to only up and down movement. Since the electrolytic module 12 is suspended on the upper cover 102 and is not fixed to the box body 100 by screws or other means, the upper cover 102 is subjected to pressure and the electrolytic module 12 is linked to the electrolytic module 12, which may cause the electrolytic module 12 to tilt in the accommodating space 104. Therefore, the third positioning structure 1000 and the fourth positioning structure 1202 allow the box body 100 and the electrolytic module 12 to only move up and down relative to each other, which can prevent the electrolytic module 12 from tilting in the water tank 10 and causing water leakage and air leakage.

In this specific embodiment, the number of the third positioning structure 1000 and the fourth positioning structure 1202 is 3, respectively, and they are arranged at the positions shown in FIG. 4 and FIG. 5. In practice, the present invention does not limit the number and position of the third positioning structure and the fourth positioning structure, which depends on the needs of the user or designer. However, in order to effectively limit the entire electrolytic module to move only in the up and down directions, the number of the third positioning structure and the fourth positioning structure can be at least two or more, and they are distributed at different positions on the bottom of the box body and the electrolytic shell, so that the electrolytic module can be effectively prevented from tilting sideways in the water tank. In addition, it should be noted that the first positioning structure 1024 of the upper cover 102 and the second positioning structure 128 of the electrolytic housing 120 are coupled to each other. In addition to positioning the relative relationship between the upper cover 102 and the electrolytic module 12, the electrolytic module 12 can also move up and down as the upper cover 102 deforms or returns to its original state.

In addition, as shown in FIG. 5 , the bottom of the electrolytic shell 120 has a plurality of lower openings 129, which, as described above, connect the electrode flow channel formed by the plurality of electrodes in the electrolytic shell 120 and the lower half of the accommodation space 104. Since the electrolytic module 12 is disposed in the accommodation space 104 of the water tank 10 and can be immersed in water, the water in the water tank 10 can be directly received through the lower openings 129 to perform electrolysis and generate hydrogen-containing gas. In this way, the electrolytic module 12 of the hydrogen generator 1 can receive water without passing through the pipeline, thereby avoiding the problem of water leakage and gas leakage caused by the pipeline being deteriorated or even falling off due to long-term use.

In summary, the electrolytic module of the hydrogen generator of the present embodiment is suspended in the water tank, and is connected to the upper cover of the water tank and is linked to the upper cover of the water tank. When the electrolytic module electrolyzes water to generate hydrogen-containing gas and the pressure in the water tank rises, the bulging deformation of the upper cover of the water tank caused by the pressure will drive the electrolytic module to move and maintain the relative position with the upper cover, so that the electrode plate extending from the electrolytic module is still sealed in the upper cover, and after long-term use, there will be no risk of irreversible deviation leading to water leakage and gas leakage. In addition, the positioning structure on the water tank body, the upper cover and the electrolytic shell can keep the electrolytic module from lateral deviation or tilt in the water tank, further avoiding the risk of leakage.

Please refer to FIG. 1 again. As shown in FIG. 1 , the condenser 14 and the humidifier 16 are both vertically stacked on the water tank 10, and the humidifier 16 is directly stacked on the water tank 10, and the condenser 14 is stacked on the humidifier 16. In practice, the hydrogen-containing gas generated by the electrolysis module 12 will first gather in the upper part of the accommodating space 104 of the water tank 10, and then enter the condenser 14 to be condensed. Therefore, the hydrogen generator 1 needs to have a channel directly connecting the water tank 10 and the condenser 14. Please refer to FIG. 6, which is a schematic diagram of the humidifier 16 of FIG. 1. As shown in FIG6 , the humidifier 16 has a humidifying space 160 and a connecting flow channel 162, wherein the humidifying space 160 is used to accommodate replenishing water, and the connecting flow channel 162 extends vertically and is isolated from the humidifying space 160, so the replenishing water in the humidifying space 160 will not enter the connecting flow channel 162. One end of the connecting flow channel 162 is connected to the water tank 10, and the other end is connected to the gas inlet of the condenser 14, so the hydrogen-containing gas in the water tank 10 can be directly input to the condenser 14 stacked on the humidifier 16 through the connecting flow channel 162 without entering the humidifying space 160 first.

After the hydrogen-containing gas is condensed by the condenser 14, it is input into the humidification space 160 to be humidified by the replenishing water. In practice, the gas outlet of the condenser 14 can be connected to a thinning tube or a thinning plate (not shown) to receive the hydrogen-containing gas output by the condenser 14. The thinning tube or the thinning plate is set in the humidification space 160 and immersed in the replenishing water. There are tiny holes on the surface, so the hydrogen-containing gas can enter the replenishing water through the tiny holes on the thinning tube or the thinning plate to form tiny bubbles and move upward. When these tiny bubbles reach the top of the humidification space 160, they have been fully humidified by the replenishing water. On the other hand, when the electrolysis module 12 stops electrolysis, the replenishing water in the humidification space 160 of the humidifier 16 can be outputted to the water tank 10 in the reverse direction along the gas path of the hydrogen-containing gas through a pump (not shown) to replenish the water lost due to electrolysis. In addition, the replenishing water can also be outputted in the reverse direction along the gas path while bringing the electrolyte left in the connecting flow channel 162 and the condenser 14 of the hydrogen-containing gas back to the water tank 10, thereby replenishing the electrolyte in the water tank 10 at the same time and maintaining the subsequent electrolysis efficiency.

Please refer to FIG. 1 again. The hydrogen generator 1 further includes an atomizer 18, which is also stacked above the water tank 10. The atomizer 18 has a gas inlet coupled to the upper part of the humidification space 160 of the humidifier 16, so that the hydrogen-containing gas can be received by the atomizer 18 after being humidified by the supplementary water in the humidification space 160. The atomizer 18 can be used to generate atomized gas, and mix it with hydrogen-containing gas to form health-care gas and output the health-care gas to the outside of the hydrogen generator 1. In practice, the atomized gas can be the gas generated after atomizing essential oils or liquid medicines, so after mixing with the hydrogen-containing gas, a health-care gas with health-care functions or even therapeutic effects can be generated. In addition, the atomizer 18 can also be controlled to not produce a mixture of atomized gas and hydrogen-containing gas. In this state, the atomizer 18 can directly output hydrogen-containing gas.

In addition, according to another specific embodiment, the hydrogen generator 1 may further include a hydrogen water cup (not shown), which may be coupled to the upper part of the humidification space 160 of the humidifier 16 to receive the hydrogen-containing gas humidified by the supplementary water, and the hydrogen water cup may contain drinkable water. After receiving the hydrogen-containing gas, the hydrogen water cup introduces it into the contained water, so that the hydrogen-containing gas dissolves in the water to generate drinkable hydrogen water. In this specific embodiment, the hydrogen water cup may be connected between the humidifier 16 and the atomizer 18, that is, the hydrogen-containing gas will flow from the humidification space 160 into the hydrogen water cup, and the hydrogen-containing gas not dissolved in the water in the hydrogen water cup will enter the atomizer 18 and be output to the outside of the hydrogen generator 1. In another specific embodiment, the hydrogen water cup and the atomizer 18 can be respectively coupled to the humidification space 160 of the humidifier 16, and both can receive hydrogen-containing gas from the humidification space 160 to respectively generate hydrogen water or output health gas or hydrogen-containing gas.

In summary, the hydrogen generator of the present invention can generate hydrogen-containing gas by electrolysis, and generate and output clean hydrogen-containing gas for users to inhale through condensation, humidification and other means, or output health-care gas in combination with atomized medicine or atomized essential oil. The electrolysis module of the hydrogen generator is suspended in the water tank, and is connected to the upper cover of the water tank and is linked to the upper cover of the water tank. Therefore, when the electrolysis module generates hydrogen-containing gas and the pressure in the water tank rises, the bulging deformation caused by the pressure on the water tank cover will drive the electrolysis module to move and maintain its relative position with the cover. Therefore, the electrode plates extending from the electrolysis module are still sealed in the cover, and there will be no risk of irreversible deviation and water or gas leakage after long-term use.
