Description

hydrogen generation device Technical Field

[0001] This invention relates to a hydrogen generating device, and more specifically, to a hydrogen generating device having a series or parallel electrolysis module and a multi-stage filtration process. Background Technology

[0002] Humans have always placed great importance on life, and many medical technologies have been developed to combat disease and prolong human life. Past medical practices were largely reactive, addressing symptoms only after disease occurred, such as surgery, medication, chemotherapy and radiation therapy for cancer, or the management, rehabilitation, and correction of chronic diseases. However, in recent years, many medical experts have increasingly focused on preventative medicine, such as research into health supplements, screening for and early prevention of hereditary diseases, proactively addressing potential future illnesses. Furthermore, to extend human lifespan, many anti-aging and antioxidant technologies have been developed and widely adopted, including topical skincare products and antioxidant foods / medications.

[0003] Research has found that unstable oxygen (O+), also known as free radicals (harmful free radicals), generated in the human body due to various reasons (such as disease, diet, environment, or lifestyle), can mix with inhaled hydrogen to form some water, which is then excreted from the body. This indirectly reduces the number of free radicals in the body, restoring an acidic body to a healthy alkaline state. This can have antioxidant and anti-aging effects, thereby also achieving the effects of eliminating chronic diseases and beauty and health care.

[0004] Generally, hydrogen generators are placed indoors, and the hydrogen produced is output for users to inhale. To increase the amount of hydrogen inhaled, besides increasing the duration of inhalation (e.g., inhaling hydrogen during sleep) to enhance its effectiveness, the generator's output can also be increased to allow users to inhale more hydrogen. When a hydrogen generator operates for extended periods, many components (such as the electrolysis unit and condenser) require cleaning or replacement due to electrolyte residue or wear and tear on consumables. However, in existing hydrogen generators, the electrolysis unit is located in a water tank. This means that users must first disconnect other components connected to the water tank and disassemble the tank itself to remove the electrolysis unit, increasing replacement and maintenance costs. Summary of the Invention

[0063] Please refer to Figures 1 through 6. Figure 1 shows a schematic diagram of the structure of a hydrogen generating device E according to a specific embodiment of the present invention. Figure 2 shows a functional block diagram of the hydrogen generating device E of Figure 1. Figure 3 shows an exploded view of the hydrogen generating device E of Figure 1. Figure 4A shows an exploded view of the water tank 11 and the electrolysis module 12 of Figure 1. Figure 4B shows an exploded view of the electrolysis module 12 of Figure 4A. Figure 5 shows a schematic diagram of the structure of the first humidifier 31 and the second humidifier 32 of Figure 1. Figure 6 shows a schematic diagram of the structure of the condenser 2 according to a specific embodiment of the present invention. As shown in Figures 1 through 3, in this specific embodiment, the hydrogen generating device E includes a water tank 11, two electrolysis modules 12, a condenser 2, a first humidifier 31, a second humidifier 32 (which can be collectively referred to as a humidification module), an integrated flow channel device 4, and an active filter tube 61. The exterior of the water tank 11 and the exterior of the humidification module include multiple staggered rib structures to increase strength. Electrolysis modules 12 are disposed outside the water tank 11, for example, two electrolysis modules 12 are located on the side walls of the water tank 11. A first humidifier 31 is coupled to the water tank 11, and a second humidifier 32 is coupled to the first humidifier 31. A condenser 2 is coupled to the water tank 11 and the first humidifier 31. An integrated flow channel device 4 is stacked above the first humidifier 31 and the second humidifier 32, and an activated filter tube 61 is connected to the integrated flow channel device 4. In practice, the hydrogen generating device E may include a housing and a base (not shown), the housing may cover and accommodate the above components, and the water tank 11, the first humidifier 31, and the second humidifier 32 may be mounted on the base.

[0064] As shown in Figures 1, 2, 4A, and 4B, in this specific embodiment, the water tank 11 includes a accommodating space 110, a water inlet 113, and a gas outlet 114. The accommodating space 110 is used to accommodate electrolyzed water. The water inlet 113 and the gas outlet 114 are disposed on the side wall of the water tank 11, and the water inlet 113 and the gas outlet 114 can extend outward from the side wall of the water tank 11. The water inlet 113 is located below the water surface of the electrolyzed water, and the gas outlet 114 is located above the water surface. In this specific embodiment, the hydrogen generating device E includes a first electrolysis module 12A and a second electrolysis module 12B, which are disposed outside the water tank 11 and respectively on the left and right side walls of the water tank 11. Therefore, each side wall has a water inlet 113 and a gas outlet 114 respectively connected to the first electrolysis module 12A or the second electrolysis module 12B. Two electrolysis modules 12 are connected in series to receive and electrolyze water from the water tank 11 to generate and output hydrogen-containing gas to the water tank 11. Each electrolysis module 12 includes a positive electrode plate 120, a negative electrode plate 121, a bipolar plate 1226, and a fixing assembly 122, with the positive electrode plate 120 and the negative electrode plate 121 arranged opposite to each other on the fixing assembly 122. In practice, the hydrogen generating device E includes a power supply (not shown). The positive electrode plate of the first electrolysis module 12A is connected to the positive terminal of the power supply, the negative electrode plate of the first electrolysis module 12A is electrically connected to the positive electrode plate of the second electrolysis module 12B, and the negative electrode plate of the second electrolysis module 12B is electrically connected to the negative terminal of the power supply, so that the two electrolysis modules 12 are connected in series. Therefore, the power supply of the hydrogen generating device E can drive the two electrolysis modules 12 with a low voltage output. The connection method of the two electrolysis modules is not limited to this. In one specific embodiment, the first electrolysis module and the second electrolysis module may also be electrically connected to the power supply in parallel.

[0065] In this specific embodiment, the fixing component 122 of the electrolysis module 12 includes a frame 1220 and a fixing structure 1225. The frame 1220 is annular and has a first surface 1221 and a second surface 1222 that are opposite to each other. The positive electrode plate 120 is disposed on the first surface 1221, and the negative electrode plate 121 is disposed on the second surface 1222. At this time, an electrolysis cavity 1223 is formed between the positive electrode plate 120, the negative electrode plate 121, and the frame 1220. The fixing structure 1225 protrudes outward from the first surface 1221 and the second surface 1222, and the frame 1220 and the fixing structure 1225 can be integrally formed. In practice, the fixing structure 1225 can be a single element or multiple elements disposed at the outer edge of the frame 1220, or even at the corner of the frame 1220. Furthermore, the area enclosed by the fixing structure 1225 can be slightly smaller than the dimensions of the positive electrode plate 120 and the negative electrode plate 121, so that the positive electrode plate 120 and the negative electrode plate 121 can be snapped together and fixed on the frame 1220. In practical applications, the fixing structure is not limited to the position shown in Figure 4B, and the position of the fixing structure can be determined according to the design or requirements.

[0066] In this specific embodiment, the electrolysis module 12 further includes a bipolar plate 1226 disposed within the frame 1220 and located between the positive electrode plate 120 and the negative electrode plate 121. In practice, the frame 1220 and the fixing structure 1225 can be directly surrounding the bipolar plate 1226 by injection molding. In this case, the bipolar plate 1226 can divide the electrolysis chamber 1223 into two chambers. When the electrolysis module 12 is connected to a power source, electrode channels are formed between the bipolar plate 1226 and the positive electrode plate 120, and between the bipolar plate 1226 and the negative electrode plate 121, respectively, to electrolyze the electrolyzed water and generate hydrogen-containing gas. The distance between the bipolar plate 1226 and the positive electrode plate 120, and the distance between the bipolar plate 1226 and the negative electrode plate 121, can be 2 mm to 5 mm. Furthermore, the bipolar plate 1226 may further include at least one hole 1227 to allow electrolyzed water and hydrogen-containing gas to flow between the two chambers.

[0067] Furthermore, the electrolysis module 12 includes a water inlet pipe 123 and a gas outlet pipe 124. In this specific embodiment, the water inlet pipe 123 and the gas outlet pipe 124 are disposed on the positive electrode plate 120 (i.e., the water inlet pipe 123 and the gas outlet pipe 124 are located on the same side of the electrolysis module 12), and the water inlet pipe 123 and the gas outlet pipe 124 are connected to the electrolysis chamber 1223. The positions of the water inlet pipe 123 and the gas outlet pipe 124 can respectively correspond to the positions of the water inlet interface 113 and the gas outlet interface 114 of the water tank 11, and the electrolysis module 12 can be directly installed on the water tank 11 and connected to the accommodating space 110 by engaging the water inlet pipe 123 and the gas outlet pipe 124 respectively, without the need for additional water pipes / pipelines. Similarly, both the left and right side walls of the water tank 11 have water inlet ports 113 and air outlet ports 114 for the installation of the first electrolysis module 12A and the second electrolysis module 12B.

[0068] In practice, the water inlet pipe 123 and the air outlet pipe 124 may further include waterproof rubber rings to increase the stability and firmness of the electrolysis module 12 installed on the water tank 11, and to prevent the electrolyzed water from leaking out of the water tank 11. Furthermore, the frame 1220 and the fixing structure 1225 can also serve as waterproof partitions, and the fixing structure 1225 can tightly attach the positive electrode plate 120 and the negative electrode plate 121 to the frame 1220 to prevent the electrolyzed water in the electrolysis module 12 from leaking out. Furthermore, the first surface 1221 and the second surface 1222 of the frame 1220 may have grooves (not shown), and the fixing component 122 may also include a waterproof rubber ring disposed in the groove, and the positive electrode plate 120 and the negative electrode plate 121 are fixed to the fixing component 122 by screws or other fixing devices, so that the waterproof rubber ring is located between the positive electrode plate 120 and the frame 1220 and between the negative electrode plate 121 and the frame 1220, thereby preventing the electrolyzed water in the electrolysis module 12 from leaking out.

[0069] When the electrolysis module 12 is operating, the electrolyzed water in the water tank 11 flows through the inlet pipe 123 and into the electrolysis chamber of the electrolysis module 12. After electrical energy is applied to the positive electrode plate 120 and the negative electrode plate 121, the electrolyzed water in the electrolysis chamber is electrolyzed to produce hydrogen-containing gas. The hydrogen-containing gas then flows through the outlet pipe 124 and is output to the accommodating space 110 of the water tank 11. In practical applications, the electrolysis module 12 is a detachable component. Therefore, when the electrode plates of the electrolysis module 12 need to be replaced or cleaned, the electrolysis module 12 can be directly removed from the water tank 11 without disassembling the water tank 11.

[0070] As shown in Figures 1, 2, and 6, in this specific embodiment, the condenser 2 is positioned above the water tank 11 to receive and condense hydrogen-containing gas from the water tank 11 and output the condensed hydrogen-containing gas. The water tank 11 may further include a condensation interface 116, located at the top of the water tank 11 and connected to the accommodating space 110. The condenser 2 includes a condensation inlet 21, a condensation outlet 22, and a condensation channel 23. The condensation inlet 21 connects to the condensation interface 116, and the condensation channel 23 is located between the condensation inlet 21 and the condensation outlet 22. In practice, the condenser 2 may be a condenser tube (or may include heat dissipation fins located on the surface of the condenser tube). When the hydrogen-containing gas generated by the electrolysis module 12 flows to the accommodating space 110 of the water tank 11, the hydrogen-containing gas can flow through the condensation interface 116 to the condenser 2, and the hydrogen-containing gas received by the condenser 2 through the condensation inlet 21 can flow in the condensation channel 23 to condense and filter the hydrogen-containing gas. The condensed hydrogen-containing gas can be output through the condensation outlet 22. As shown in Figure 6, in this specific embodiment, the condenser 2 is spiral-shaped to increase the length of the condensation channel 23, thereby improving the filtration and condensation effects. However, the shape of the condenser is not limited to this in practice, and the shape of the condenser can be designed according to requirements.

[0071] Please refer to Figures 1, 2, 5, and 7 together. Figure 7 shows a schematic diagram of the structure of the refining device 5 according to a specific embodiment of the present invention. As shown in Figures 1, 2, 5, and 7, in this specific embodiment, the first humidifier 31 is disposed adjacent to the water tank 11 and has a first humidification chamber 310 and an air inlet column 312. The first humidification chamber 310 is used to contain makeup water. The air inlet column 312 is connected to the condensation outlet 22 of the condenser 2 (e.g., the condensation output channel 42 of the integrated flow channel 4), and the air inlet column 312 is isolated from the first humidification chamber 310. After the condenser 2 condenses the hydrogen-containing gas, the condensed hydrogen-containing gas first flows through the air inlet column 312, then flows into the makeup water in the first humidification chamber 310, and finally the first humidifier 31 filters and humidifies the condensed hydrogen-containing gas.

[0072] In this specific embodiment, the aerating device 5 can be disposed at the bottom of the first humidifier 31 and includes the first aerating device 51. The first aerating device 51 includes a first aerating channel 510 and a first bubbler 512. The first aerating channel 510 connects the air intake column 312 and the first bubbler 512, and the first bubbler 512 is disposed in the makeup water of the first humidification chamber 310. When the air intake column 312 receives the condensed hydrogen-containing gas, the hydrogen-containing gas first flows through the first aerating channel 510, and then flows through the first bubbler 512 to the first humidification chamber 310. Further, the surface of the first bubbler 512 may include multiple micro-bubble structures, allowing the hydrogen-containing gas to pass through these micro-bubble structures. When the hydrogen-containing gas enters the makeup water through the micro-bubble structures, it can be aerated into tiny bubbles, allowing the hydrogen-containing gas to be fully filtered and humidified by the makeup water in the first humidification chamber 310.

[0073] In this specific embodiment, the second humidifier 32 is disposed adjacent to the first humidifier 31 and has a second humidification chamber 320 for containing makeup water. Furthermore, the first humidifier 31 further includes a connecting inlet column 314 connecting the first humidification chamber 310 and the second humidification chamber 320, and the connecting inlet column 314 and the second humidification chamber 320 are isolated from each other. The connecting inlet column 314 has an inlet port 3141 and an outlet port 3142 respectively disposed at its two ends, and the position of the inlet port 3141 is higher than the water surface of the makeup water in the first humidification chamber 310. After the first humidifier 31 humidifies the hydrogen-containing gas, the hydrogen-containing gas can flow through the inlet port 3141 to the connecting inlet column 314, and then through the outlet port 3142 to the makeup water in the second humidification chamber 320. Finally, the second humidifier 32 filters and humidifies the hydrogen-containing gas again.

[0074] In this specific embodiment, the refining device 5 further includes a second refining device 52. The second refining device 52 includes a second refining channel 520 and a second bubbler 522. The second refining channel 520 connects the inlet column 314 and the second bubbler 522, and the second bubbler 522 is disposed in the makeup water of the second humidification chamber 320. When hydrogen-containing gas flows through the inlet column 314, the hydrogen-containing gas flows through the outlet 3142 to the second refining channel 520, and then flows through the second bubbler 522 to the second humidification chamber 320. Similarly, the surface of the second bubbler 522 also includes multiple micro-bubble structures, so that the hydrogen-containing gas can be sufficiently filtered and humidified by the makeup water in the second humidification chamber 320. It is worth noting that the first refining channel 510 and the second refining channel 520 of the refining device 5 are not interconnected.

[0075] In this specific embodiment, the water tank 11, the first humidifier 31, and the second humidifier 32 are horizontally isolated from each other, and the first humidifier 31 and the second humidifier 32 are integrally formed in a single component, but this is not the only practical application. In one specific embodiment, the water tank, the first humidifier, and the second humidifier may also be integrally formed in a single component.

[0076] In this specific embodiment, the integrated flow channel device 4 is disposed above the first humidifier 31 and the second humidifier 32 and includes a condenser output flow channel 42. The condenser output flow channel 42 connects the condenser outlet 22 of the condenser and the inlet column 312 of the first humidifier 31, and is used to introduce the condensed hydrogen-containing gas into the inlet column 312. The condenser 2 is disposed above the water tank 11 and the integrated flow channel device 4. Therefore, when the condenser 2 needs to be replaced or cleaned, the condenser 2 can be directly removed from the water tank 11 and the integrated flow channel device 4.

[0077] Please refer to Figures 2, 8, and 9A together. Figure 8 shows a top view of the hydrogen generating device E of Figure 1. Figure 9A shows a partial cross-sectional view of the hydrogen generating device E along line AA in Figure 8. The arrows in Figure 9A indicate the flow direction of the hydrogen-containing gas. When the hydrogen generating device E of the present invention is in operation, the hydrogen-containing gas generated by the two electrolysis modules 12 first flows to the containment space 110 in the water tank 11. Then, the hydrogen-containing gas flows through the condensation port 116 of the water tank 11 to the condenser 2 for condensation and filtration. The condensed hydrogen-containing gas then flows sequentially through the condensation output channel 42, the inlet column 312, the first finer channel 510, and the first bubbler 512, and flows into the makeup water of the first humidification chamber 310 for the first stage of filtration and humidification. Next, the humidified hydrogen-containing gas flows through the flow channel formed by the inner wall of the integrated flow channel device 4 and the outer wall of the connecting inlet column 314 and flows to the gas inlet 3141 of the connecting inlet column 314. Then, it flows sequentially through the connecting inlet column 314, the second fine flow channel 520 and the second aerator 522 and flows to the makeup water of the second humidification chamber 320 for the second filtration and humidification.

[0078] Furthermore, in this specific embodiment, the hydrogen generating device E may further include a metal element 66 disposed in the accommodating space 110 of the water tank 11 and the first humidification chamber 310. In practice, the metal element 66 may be a metal spring, with one end of the spring contacting the water in the water tank 11 for electrolysis and the other end contacting the inner wall of the condenser 2, so that the water in the water tank 11 and the condenser 2 are at the same potential. Another metal element 66 has one end contacting the inner wall of the condenser 2 and the other end connected to the replenishment water of the first humidifier 31, so that the water in the first humidifier 31 and the condenser 2 are at the same potential. This achieves equipotentiality between the water tank 11 and the first humidifier 31.

[0079] Please refer to Figures 1, 2, 3, and 9B. Figure 9B shows a partial cross-sectional view of the hydrogen generating device E along line AA in Figure 8. The arrows in Figure 9B indicate the flow direction of the hydrogen-containing gas. In this specific embodiment, the hydrogen generating device E further includes an active filter tube 61 connected to the integrated flow channel device 4. As shown in Figure 9B, the active filter tube 61 includes a filter inlet tube 611, a filter outlet tube 612, and a filter element 613. The integrated flow channel device 4 further includes an outlet flow channel 44, which connects to the second humidification chamber 320 and the filter inlet tube 611. The filter element 613 is disposed in the filter inlet tube 611 and is used to filter impurities in the hydrogen-containing gas. The filter inlet tube 611 and the filter outlet tube 612 are respectively connected to both ends of the filter element 613. After the second humidifier 32 humidifies the hydrogen-containing gas, the hydrogen-containing gas can flow through the outlet flow channel 44 and to the filter inlet tube 611 of the active filter tube 61. Next, the hydrogen-containing gas enters the filter element 613 from the bottom of the filter inlet pipe 611 for filtration, and finally the hydrogen-containing gas is output from the filter outlet pipe 612.

[0080] In this specific embodiment, the hydrogen generating device E further includes a hydrogen water cup 62 coupled to the activated filter tube 61 and used to contain a liquid (such as drinking water). The hydrogen water cup 62 is used to receive filtered hydrogen-containing gas into the liquid to form a hydrogen-containing liquid. As shown in FIG9B, the hydrogen generating device E further includes a connector 63, and the connector 63 includes a gas connection pipe 631. The hydrogen water cup 62 is detachably connected to the connector 63, and the gas connection pipe 631 is in fluid communication with the filter outlet pipe 612 of the activated filter tube 61 and the hydrogen water cup 62. In addition, the hydrogen water cup 62 may include a foaming rod 621 connected to the gas connection pipe 631 and in contact with the liquid in the hydrogen water cup 62. After the filtered hydrogen-containing gas is output from the filter outlet pipe 612 of the active filter tube 61, the hydrogen-containing gas can flow sequentially through the gas connection pipe 631 and the foaming rod 621. The foaming rod 621 can refine the hydrogen-containing gas into tiny bubbles so that the hydrogen-containing gas can be fully mixed with the liquid to form a hydrogen-containing liquid for the user to drink.

[0081] Please refer to Figures 3, 8, and 10 together. Figure 10 shows a cross-sectional view along line BB of Figure 8. The arrows in Figure 10 indicate the flow direction of the hydrogen-containing gas. In this specific embodiment, the connector 63 further includes a gas output pipe 632 with an outlet 633, and the gas output pipe 632 connects the hydrogen water cup 62 and the external environment. In practice, when the hydrogen-containing gas flows through the foaming rod 621 to the hydrogen water cup 62, a portion of the hydrogen-containing gas can mix with the liquid to form a hydrogen-containing liquid, while another portion of the hydrogen-containing gas can flow through the gas output pipe 632 and be output to the external environment through the outlet 633 for the user to inhale. In one specific embodiment, the connector may also include a switching device and a switching channel (not shown). When the hydrogen water cup is detached from the connector, the switching device can be activated to connect the gas connection pipe, the switching channel, and the gas output pipe, so that the hydrogen-containing gas filtered by the active filter tube can be directly output to the external environment from the outlet without flowing to the foaming rod.

[0082] In this specific embodiment, the hydrogen generating device E further includes a flame arrester 65 disposed in the gas output line 632. In practice, the flame arrester 65 may include a one-way check valve to allow gas to pass through in only one direction, preventing backflow of other gases and reducing or preventing the spread of accidentally ignited gas to the hydrogen generating device E. Furthermore, the flame arrester 65 may also contain extremely fine pores (such as a flame arrester 65 compressed from micro-wires into a block shape), the pores allowing gas to pass through but preventing flames from penetrating the flame arrester 65, thereby improving safety.

[0083] As shown in Figures 9A, 9B, and 10, the hydrogen-containing gas generated by the electrolysis module of the hydrogen generation device E of the present invention can first be condensed and filtered by the condenser 2, then humidified and filtered by the first humidifier 31, then humidified and filtered by the second humidifier 32, and finally filtered by the activated carbon filter tube 61, thus performing a multi-stage filtration process to improve the purity of the hydrogen-containing gas. Furthermore, the filtered hydrogen-containing gas can also be formulated into a drinkable hydrogen-containing liquid or directly output for inhalation, depending on the user's needs, thereby increasing versatility and convenience.

[0084] Please refer again to Figures 2, 3, and 9A. In this specific embodiment, the integrated flow channel device 4 further includes a water supply pipe 46 in fluid communication with the second humidifier 32. The water supply pipe 46 is used to receive and replenish the replenished water into the second humidification chamber 320. In addition, the hydrogen generating device E further includes a first water supply pump 71 and a second water supply pump 72. The first water supply pump 71 is connected to the first humidifier 31 and the second humidifier 32, and is used to replenish the replenished water in the second humidifier 32 to the first humidifier 31. The second water supply pump 72 is connected to the water tank 11 and the first humidifier 31, and is used to replenish the replenished water in the first humidifier 31 to the accommodating space 110 of the water tank 11. In practice, since the water volume of the hydrogen generating device E will gradually decrease after a long reaction period, the user can add water through the water supply pipe 46, and then replenish the water volume of the water tank 11 sequentially through the first water supply pump 71 and the second water supply pump 72.

[0085] In summary, the electrolysis module of the hydrogen generation device of the present invention is located outside the water tank. Therefore, the electrolysis module can be directly removed from the water tank without disassembling the tank, thereby reducing installation and maintenance time and improving assembly efficiency. Furthermore, the hydrogen generation device of the present invention includes multiple filtration processes to filter hydrogen-containing gas, thereby improving the purity of the hydrogen-containing gas. In addition, the filtered hydrogen-containing gas can be used to form a drinkable hydrogen-containing liquid or directly output for inhalation, depending on the user's needs, thus increasing versatility and convenience.
