Description

Technical Field

[0001] This invention relates to a hydrogen generating device, and more specifically, to a hydrogen generating device with a pressure relief function. 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 habits), 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, which can have antioxidant and anti-aging effects, thereby also achieving the effects of eliminating chronic diseases and beauty and health care. Increasing the duration of hydrogen inhalation (e.g., inhaling hydrogen during sleep) can also effectively enhance the efficacy of inhaled hydrogen.

[0004] Currently, commercially available hydrogen generation equipment typically produces hydrogen through water electrolysis. When the equipment produces hydrogen, the electrolysis unit increases its operating temperature due to electrolysis, which in turn raises the temperature of the water tank. Conversely, when the electrolysis unit stops operating, its operating temperature gradually decreases, causing a drop in gas pressure within the water tank and creating a negative pressure. Because the piping in typical hydrogen generation equipment is closed-loop, the pressure inside the water tank cannot balance with the external environmental pressure, potentially leading to tank deformation. Furthermore, other components of the hydrogen generation equipment may contain other liquids, which could flow back into the tank due to the negative pressure, contaminating the electrolyzed water and reducing electrolysis efficiency. Moreover, if too much other liquid flows back into the tank, causing the water level to rise excessively, it could also lead to tank rupture.

[0005] Therefore, it is necessary to develop a new type of hydrogen production equipment to solve the problems of previous technologies. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a hydrogen generation device with a pressure relief function, which has a simple structure, is easy to operate and maintain, can solve the problems of the prior art, and can effectively improve safety, improve electrolysis efficiency, and reduce costs.

[0007] To achieve the above objectives, the present invention discloses a hydrogen generation device with a pressure relief function, characterized in that it comprises:

[0008] A water tank having a containment space for containing electrolyzed water;

[0009] An electrolytic cell is disposed in the containment space of the water tank for receiving and electrolyzing the electrolyzed water from the water tank to generate and output a hydrogen-containing gas.

[0010] A humidification cup is disposed above the water tank. The humidification cup includes a humidification chamber and a gas channel. The humidification cup is used to receive and humidify the hydrogen-containing gas. The humidification chamber and the gas channel are isolated from each other, and the gas channel is connected to the water tank.

[0011] A first valve element for selectively connecting the humidification chamber to an external environment; and

[0012] A second valve element for selectively connecting the accommodating space and the humidification chamber;

[0013] When the electrolytic cell stops operating, outside air from the external environment enters the containment space through the first valve element and the second valve element.

[0014] When the electrolytic cell is operating, the first valve element and the second valve element are closed; when the electrolytic cell stops operating, the first valve element and the second valve element are opened, so that the accommodating space, the gas passage, the humidification chamber, the first valve element and the second valve element form a continuous channel, which allows outside air to enter the water tank to balance the pressure of the water tank.

[0015] The device further includes an integrated flow channel device disposed above the water tank. The integrated flow channel device includes an inlet flow channel and an outlet flow channel. The inlet flow channel is used to receive the hydrogen-containing gas, and the outlet flow channel is used to output the hydrogen-containing gas. The first valve element and the second valve element are disposed on the integrated flow channel device.

[0016] The device further includes an atomizer coupled to the outlet channel to receive the hydrogen-containing gas. The atomizer can selectively generate an atomized gas to mix with the hydrogen-containing gas to form a health-promoting gas.

[0017] The device further includes a condensation filter coupled to the integrated flow channel device, and the humidification cup includes a connecting chamber for connecting the water tank and the condensation filter, and the condensation filter for receiving and filtering the hydrogen-containing gas from the connecting chamber.

[0018] The device further includes a foaming rod disposed in the humidification chamber of the humidification cup and coupled to the condensation filter device.

[0019] The device further includes a hydrogen water cup for containing a liquid, wherein the hydrogen water cup is used to inject the hydrogen-containing gas into the liquid to form a hydrogen-containing liquid.

[0020] The device further includes an ozone generator, wherein a gas flow path is formed between the integrated flow channel device and the electrolytic cell for the hydrogen-containing gas to flow therethrough, and the ozone generator is coupled to the gas flow path. The ozone generator is used to generate ozone to enter the gas flow path to disinfect the gas flow path when the electrolytic cell stops electrolyzing.

[0021] The device further includes a filter disposed at an outlet of the hydrogen generating device, the filter being used to filter the hydrogen-containing gas at the outlet.

[0022] The pH value of the electrolyzed water is between 13 and 13.9.

[0023] A hydrogen generation device with a pressure relief function is also disclosed, characterized by comprising:

[0024] A water tank having a containment space for containing electrolyzed water;

[0025] An electrolytic cell is disposed in the containment space of the water tank for receiving and electrolyzing the electrolyzed water from the water tank to generate and output a hydrogen-containing gas.

[0026] An integrated flow channel device is disposed above the water tank. The integrated flow channel device includes an inlet flow channel and an outlet flow channel. The inlet flow channel is used to receive the hydrogen-containing gas, and the outlet flow channel is used to output the hydrogen-containing gas.

[0027] A pressure relief module, which, when the electrolytic cell stops operating, activates to allow ambient air to enter the water tank; and

[0028] A humidification cup, coupled to the integrated flow channel device, is used to humidify the hydrogen-containing gas;

[0029] The pH value of the electrolyzed water is between 12 and 14.

[0030] The device further includes an atomizer coupled to the outlet channel to receive the hydrogen-containing gas. The atomizer can selectively generate an atomized gas to mix with the hydrogen-containing gas to form a health-promoting gas.

[0031] The device further includes a filter disposed at an outlet of the hydrogen generating device, the filter being used to filter the hydrogen-containing gas at the outlet.

[0032] The device further includes an ultraviolet light source disposed in the hydrogen generating device, which emits ultraviolet light to sterilize the hydrogen generating device.

[0033] The device further includes a condensation filter coupled to the integrated flow channel device, and the humidification cup includes a connecting chamber for connecting the water tank and the condensation filter, and the condensation filter for receiving and filtering the hydrogen-containing gas flowing through the connecting chamber.

[0034] The device further includes a hydrogen water cup for containing a liquid, wherein the hydrogen water cup is used to inject the hydrogen-containing gas into the liquid to form a hydrogen-containing liquid.

[0035] The device further includes an ozone generator, wherein a gas flow path is formed between the integrated flow channel device, the electrolytic cell, and the hydrogen water cup for the hydrogen-containing gas to flow therethrough, and the ozone generator is coupled to the gas flow path. The ozone generator is used to generate ozone to enter the gas flow path when the electrolytic cell stops electrolyzing, so as to disinfect the gas flow path.

[0036] The pressure relief module includes a first valve element and a second valve element. The first valve element is used to selectively connect the humidification chamber to the external environment, and the second valve element is used to selectively connect the accommodating space to the humidification chamber. When the electrolytic cell stops operating, the first valve element and the second valve element open to allow outside air from the external environment to enter the accommodating space through the first valve element and the second valve element.

[0037] It further includes a flame arrester coupled to the first valve element.

[0038] This further includes:

[0039] A housing for accommodating the water tank, the electrolytic cell, the integrated flow channel, the condenser filter, the pressure relief module, and the humidification cup; and

[0040] A bucket support is provided for supporting a bucket located outside the housing, thereby providing replenishment water so that the replenishment water flows through the condensation filter into the water tank.

[0041] The device further includes a baffle assembly disposed in the communicating chamber. The baffle assembly is used to reduce or prevent water vapor and electrolyte in the hydrogen-containing gas flowing through the baffle assembly from reaching the integrated flow channel device.

[0042] In summary, the hydrogen generator with pressure relief function of the present invention allows for the introduction of outside air to balance the pressure in the water tank when the electrolyzer is not operating, through the opening of the first and second valve elements, thus preventing the water tank from deforming due to pressure differences and improving safety. Furthermore, the hydrogen generator with pressure relief function of the present invention can prevent other liquids from flowing back into the water tank, thereby contaminating the electrolyzed water or causing the water level in the tank to become too high, leading to excessive pressure and rupture, thus improving electrolysis efficiency and safety. Moreover, the hydrogen generator with pressure relief function of the present invention can also continuously perform self-disinfection and self-sterilization through alkaline electrolysis environments, temperature environments unfavorable to bacteria or bacteria survival, and various devices such as filters, ultraviolet light sources, and ozone generators. In addition to providing users with germ-free, pure hydrogen-containing gas or health-promoting gas, it can also significantly reduce the maintenance costs of the hydrogen generator. Furthermore, the hydrogen generator with pressure relief function of the present invention can also prevent electrolyte from flowing into the humidification chamber and maintain the electrolyte concentration in the electrolyzed water by using an external water tank to backflush the electrolyte and a baffle plate assembly, thereby maintaining electrolysis efficiency. In addition, the hydrogen generator with pressure relief function of the present invention can also have a flame arrester installed on the continuous channel to prevent the spread of accidentally ignited gas to the outside of the hydrogen generator, thereby improving safety.

Figure 1 A schematic diagram of a hydrogen generation device E with a pressure relief function according to a specific embodiment of the present invention is shown. Figure 2 A functional block diagram of a hydrogen generating device E with a pressure relief function according to a specific embodiment of the present invention is shown. Figure 3 Showing according to Figure 1 An exploded view of a hydrogen generator E with a pressure relief function. Figure 4 Showing according to Figure 1 Exploded view of water tank 1. Figure 5A Showing according to Figure 1 A schematic diagram of a hydrogen generator with pressure relief function from another perspective. (See diagram below.) Figures 1 to 5A As shown, in this specific embodiment, the hydrogen generating device E with pressure relief function includes a water tank 1, an electrolytic cell 2, a humidification cup 4, and a pressure relief module 5, wherein the pressure relief module 5 includes a first valve element 51 and a second valve element 52. The water tank 1 has a accommodating space 111 to accommodate electrolyzed water. The electrolytic cell 2 is disposed in the accommodating space 111 of the water tank and is used to receive and electrolyze the electrolyzed water from the water tank 1 to generate and output hydrogen-containing gas. The humidification cup 4 is disposed above the water tank 1 and is used to receive and humidify the hydrogen-containing gas. The humidification cup 4 includes a humidification chamber 40 and a gas passage 41. The humidification chamber 40 and the gas passage 41 are isolated from each other, and the gas passage 41 is connected to the water tank 1. The first valve element 51 is coupled to the humidification chamber 40 and is used to selectively connect the humidification chamber 40 to the external environment. The second valve element 52 is coupled to the gas passage 41 and is used to selectively connect the accommodating space 111 and the humidification chamber 40.

[0061] In this specific embodiment, the water tank 1 may include a cover 10 and a tank body 11. The tank body 11 forms a receiving space 111 to receive electrolyzed water, and the cover 10 can cover the tank body 11. The electrolytic cell 2 can be disposed in the receiving space 111 of the water tank 1 and used to electrolyze the electrolyzed water to generate and output hydrogen-containing gas. The electrolytic cell 2 includes an electrode plate assembly 20 and an electrolytic cell fixing plate 21, and the electrolytic cell fixing plate 21 includes an electrolytic cell body 210 and a partition plate 211. The electrode plate assembly 20 can be accommodated in the electrolytic cell body 210 of the electrolytic cell fixing plate 21. The electrode plate assembly 20 includes a plurality of electrode plates 200 and a pad 201 connecting each electrode plate 200. The pad 201 is disposed on the upper surface of each electrode plate 200 so that the plurality of electrode plates 200 are spaced apart so that when the electrode plate assembly 20 is accommodated in the electrolytic cell body 210, a plurality of electrode flow channels can be formed. The partition plate 211 can be used to fix the electrolytic cell 2 in the water tank 1 and divide the water tank 1 into upper and lower layers, so that the electrolyzed water is mainly located in the lower layer, while the hydrogen-containing gas produced by electrolysis is mainly located in the upper layer. In order to maintain the flow between the upper and lower layers, the partition plate 211 has multiple flow holes 2110 to connect the upper and lower layers. The electrolytic cell fixing plate 21 can be a one-piece molded structure. In addition, it is understood that those skilled in the art can design the shape of the partition plate 211 according to their needs to provide space for the installation of other components.

[0062] In this specific embodiment, the pH value of the electrolyzed water used for electrolysis in the hydrogen generating device E with pressure relief function of the present invention is between 11 and 14. However, in practice, it is not limited to this; the electrolyzed water may also contain a weakly alkaline electrolyte to allow electrolysis in the electrolytic cell 2 to generate hydrogen-containing gas. The hydrogen generating device E with pressure relief function of the present invention performs electrolysis and generates hydrogen-containing gas in an alkaline environment, therefore, the alkaline electrolyzed water can have a bactericidal function. In addition, when the electrolytic cell 2 is operating, electrical energy is applied to the electrode plate assembly 20, causing multiple electrode plates 200 to form positive and negative electrodes to electrolyze the electrolyzed water in the water tank 1. Since part of the electrical energy applied to the electrode plate assembly 20 is converted into heat energy during electrolysis, the operating temperature of the electrolytic cell 2 will rise when the electrolytic cell 2 electrolyzes the electrolyzed water. In this specific embodiment, the operating temperature of the electrolytic cell 2 for electrolyzing the electrolyzed water can be between 55°C and 85°C, therefore, the electrolytic cell 2 also has a bactericidal function.

[0063] In practice, electrolyzed water may contain electrolytes with a concentration exceeding 0.1% by weight or volume (e.g., between 0.5% and 15%). Therefore, the electrolyzer 2 and water tank 1 are strongly alkaline environments with a pH value exceeding 12. Furthermore, if the electrolyzed water contains electrolytes with a concentration of 1% by weight or 1% by volume, or even higher, the pH value of the alkaline environment in the electrolyzer 2 and water tank 1 can reach above 13.4.

[0064] Experiments have shown that the electrolyzed water in the electrolytic cell 2 and water tank 1 of this invention contains an electrolyte concentration exceeding 0.1%, resulting in an internal pH value above 12. When the electrolyzed water contains 1% electrolyte, its pH value reaches 13.4; when it contains 2% electrolyte, its pH value is approximately 13.7; and when it contains 3% electrolyte, its pH value is approximately 13.88. When the electrolyte concentration is 4% or higher, the pH value reaches a maximum of 14. Experiments have shown that almost no pathogens can survive in this strongly alkaline environment with a pH of 12-14. However, excessively high electrolyte concentrations can easily generate alkaline mist during electrolysis, which, if not properly treated and filtered, can harm the human respiratory system. Conversely, electrolyte concentrations below 0.1% lead to a decrease in electrolysis efficiency. Furthermore, experiments have shown that when the electrolyte concentration reaches 6%, the noise of the hydrogen generation device is minimized. Therefore, considering the above factors such as sterilization, electrolysis efficiency, alkaline mist, and noise, the suitable electrolyte concentration range for the hydrogen generating device with pressure relief function of the present invention is 0.5% to 15%. This electrolyte concentration range will create a strongly alkaline environment with a pH value of 12 to 14 in the electrolysis tank 2 and the water tank 1 for effective sterilization. Experiments have shown that if the electrolyte concentration in the electrolyzed water is 1% to 3%, the pH value of the aforementioned strongly alkaline environment is 13 to 13.9.

[0065] Experiments revealed that the highly alkaline environment in water tank 1 and electrolysis cell 2 in the aforementioned specific embodiment was sufficient to prevent the survival of all Legionella pneumophila. Furthermore, Mycobacterium tuberculosis is a representative of alkali-resistant bacteria; when the electrolyzed water contains 0.1% electrolyte, its pH value already exceeds 12, which can also inactivate Mycobacterium tuberculosis. Further, when the electrolyzed water contains more than 1% electrolyte, reaching a high pH environment exceeding 13.4 or even approaching 14, alkali-resistant bacteria such as Mycobacterium tuberculosis also cannot survive.

[0066] Furthermore, Bacillus subtilis var. niger spores are considered among the most difficult bacteria to eradicate, exhibiting strong resistance to heat, ultraviolet light, ionizing radiation, and certain chemicals. Countries and regions such as the United States, the United Kingdom, Japan, and the European Union have included this strain in their food and medical testing standards as a quality control standard. Internationally, this strain is used as an indicator bacterium for evaluating the bactericidal effects of chemical disinfectants, dry heat, and ethylene oxide. The Chinese Ministry of Health has also included this strain as a standard testing strain in the "Disinfection Technical Specifications." This species represents a high-level disinfection method for verifying the effectiveness of disinfectants or disinfection equipment.

[0067] The hydrogen generating device with pressure relief function of the present invention also has the ability to eliminate Bacillus subtilis var. niger spores. As previously mentioned, the pH value of the alkaline environment in the electrolytic cell 2 and water tank 1 of the hydrogen generating device in each specific embodiment exceeds 12, and can even reach 13.8 or higher. Experiments have shown that the electrolyte concentration of the electrolyzed water in the water tank 1 and electrolytic cell 2 of the hydrogen generating device E is greater than 0.1%, resulting in an alkaline environment pH value greater than 12, thus preventing the survival of Bacillus subtilis var. niger spores. In addition, as mentioned above, the hydrogen-containing gas generated by the electrolytic cell also carries water vapor with a high pH value of electrolyzed water, and therefore can also sterilize or disinfect part of the gas flow path.

[0068] In this specific embodiment, the hydrogen generating device E with pressure relief function further includes an integrated flow channel device 3 and a condenser filter device 6. A humidification cup 4 is vertically stacked on the water tank 1, the integrated flow channel device 3 is vertically stacked on the humidification cup 4, and the condenser filter device 6 is placed within the receiving space of the integrated flow channel device 3. In practice, the hydrogen generating device E with pressure relief function may further include a housing to accommodate the aforementioned components.

[0069] The humidification cup 4 includes a humidification chamber 40, a gas passage 41, and a connecting chamber 42. The humidification chamber 40 contains replenishing water. The gas passage 41 and the connecting chamber 42 are isolated from the humidification chamber 40. The connecting chamber 42 can be used to connect the water tank 1 and the integrated flow channel device 3, so that the hydrogen-containing gas generated by the electrolysis cell 2 in the water tank 1 enters the integrated flow channel device 3 through the connecting chamber 42, and then enters the condensation flow channel 61 of the condensation filter device 6 from the integrated flow channel device 3. The condensation filter device 6 has a condensation flow channel 61, which allows the received hydrogen-containing gas to flow in the condensation flow channel 61 for condensation and filtration. In this specific embodiment, the condensation filter device 6 can be embedded in the integrated flow channel device 3 and can be pulled out from the side of the integrated flow channel device 3 for easy replacement without disassembling the entire hydrogen generation device E with a heat sink and pressure relief function for replacement. Figure 5A The condenser filter 6 may further include a movable, liftable structure (not shown) disposed on top of the condenser filter 6 to fix and seal the condenser channel 61. The hydrogen-containing gas filtered by the condenser filter 6 can then flow through the integrated channel device 3 to the humidification chamber 40 of the humidification cup 4, where the replenishment water can further filter and humidify the hydrogen-containing gas.

[0070] Please refer to the following: Figure 2 , Figure 3 , Figure 5A and Figure 5C . Figure 5C According to Figure 5AA cross-sectional view along line segment AA. The hydrogen generating device E with pressure relief function of the present invention further includes a water-blocking device 45 and a baffle plate assembly 46, both of which can be disposed in the communicating chamber 42. Figure 5C The enlarged view shows a portion of the water-blocking device 45, which is positioned above the water tank 1 to prevent the electrolyzed water from flowing out of the tank when it is tilted at an angle. In practical applications, the water-blocking device 45 includes a bottom 450 (circled in dashed lines) and an anti-backflow component 451. The bottom 450 has an air inlet 4500 and a resilient pin 4501. The air inlet 4500 is used to receive hydrogen-containing gas. The anti-backflow component 451 has a pin hole 4510, and the resilient pin 4501 is reversibly positioned in the pin hole 4510, holding the air inlet 4500 open by pressing against the anti-backflow component 451. When the water tank 1 or the integrated hydrogen generator E with the hydrogen water cup is tilted at an angle, the elastic pin 4501 is compressed and slid into the pin hole 4510 so that the anti-spill component 451 is coupled to the bottom 450 to close the air inlet 4500 to prevent the electrolyzed water from flowing out of the water tank 1.

[0071] The baffle plate assembly 46 can be installed above the water blocking device 45. The baffle plate assembly 46 is used to reduce or prevent water vapor and electrolyte in the hydrogen-containing gas flowing through the baffle plate assembly 46 from entering the condensation channel 61. The baffle plate assembly 46 is composed of multiple staggered plates. Furthermore, when the hydrogen-containing gas flows through the connecting chamber 42, the water vapor and electrolyte in the hydrogen-containing gas will condense on the baffle plate assembly 46 due to the obstruction. The water vapor and electrolyte condensed on the baffle plate assembly 46 will then be flushed back into the water tank 1 by the water flowing in from the integrated channel device 3 through the vacuum pump under negative pressure, so as to maintain the electrolyte concentration in the electrolyzed water and thus maintain the electrolysis efficiency.

[0072] Furthermore, the hydrogen generating device E with pressure relief function includes a foaming rod 43 disposed in the humidification chamber 40 of the humidification cup 4. The foaming rod 43 is connected to the humidification chamber 40 and the condensation channel 61 of the condensation filter device 6 to input the filtered hydrogen-containing gas into the makeup water of the humidification chamber 40. Specifically, the surface of the foaming rod 43 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 refined into tiny bubbles, allowing the hydrogen-containing gas to be fully filtered and humidified by the makeup water in the humidification chamber 40. In summary, when the hydrogen-containing gas generated by the electrolytic cell 2 leaves the water surface of the water tank 1, it will enter the connecting chamber 42 of the humidification cup 4. Then, the hydrogen-containing gas flows sequentially through the connecting chamber 42 of the humidification cup 4, the condensation channel 61 of the condensation filter device 6, the foaming rod 43, and the humidification chamber 40 of the humidification cup 4.

[0073] In this specific embodiment, the integrated flow channel device 3 includes an inlet flow channel 301 and an outlet flow channel 302. The hydrogen generating device E with pressure relief function further includes an atomizer 7 coupled to the outlet flow channel 302 of the integrated flow channel device 3 to receive hydrogen-containing gas, and can selectively generate atomized gas to mix with the hydrogen-containing gas to form a health-promoting gas. The atomizer 7 can generate an atomized gas to mix with the hydrogen-containing gas to form a health-promoting gas, wherein the atomized gas can be selected from one or a combination of water vapor, atomized medicine, and volatile essential oils. In one specific embodiment, the atomizer 7 includes an oscillator that atomizes water, atomized medicine, or volatile essential oil added to the atomizer 7 by oscillation to generate atomized gas, and then mixes the mixed gas with the atomized gas to form a health-promoting gas. The atomizer 7 can be selectively turned on or off according to the user's needs to provide the user with the health-promoting gas mixed with atomized gas for inhalation, or to provide only the mixed gas (i.e., hydrogen diluted with a second oxygen) for the user to inhale.

[0074] Furthermore, in this specific embodiment, the hydrogen generating device E with pressure relief function further includes a hydrogen water cup 8, and the integrated flow channel device 3 further includes a gas connecting channel 303. The gas connecting channel 303 can be selectively coupled to the gas flow channel 301 and the gas flow channel 302, and the gas flow channel 301 and the gas flow channel 302 can be selectively coupled to the hydrogen water cup 8. The hydrogen water cup 8 can be used to contain liquids (such as drinking water), and the hydrogen water cup 8 is used to inject hydrogen-containing gas into the drinking water to form hydrogen-containing water.

[0075] Therefore, when the electrolytic cell 2 of the hydrogen generator E with pressure relief function of the present invention electrolyzes the electrolyzed water and generates hydrogen-containing gas, the hydrogen-containing gas flows from the water tank 1 through the connecting chamber 42 of the humidification cup 4, the condensation channel 61 of the condensation filter device 6, the foaming rod 43, the humidification chamber 40 of the humidification cup 4, and the inlet channel 301 of the integrated flow channel device 3. After the hydrogen-containing gas flows to the inlet channel 301, the hydrogen-containing gas can flow sequentially to the hydrogen water cup 8, the outlet channel 302, and the atomizer 7, or it can flow sequentially through the gas connecting channel 303, the outlet channel 302, and the atomizer 7 without flowing through the hydrogen water cup 8. However, it should be understood that the above-mentioned flow direction of the hydrogen-containing gas is one embodiment of the hydrogen generator with pressure relief function of the present invention, and those skilled in the art can adjust the order of the components as needed, and are not limited thereto.

[0076] In another embodiment, the hydrogen generator with pressure relief function of the present invention introduces a large amount of *Bacillus subtilis* var. *niger* spores into a humidification cup from the outside. Since the humidification cup is connected to units such as a water tank, electrolyzer, hydrogen water cup, and condenser filter through an integrated flow channel device, and the humidification cup outputs replenishment water to the water tank, electrolyzer, and condenser filter in the reverse direction through a hydrogen-containing gas flow path (i.e., the gas flow path and liquid flow path are the same, but the flow directions of the hydrogen-containing gas and replenishment water are opposite), *Bacillus subtilis* var. *niger* spores will enter the aforementioned units, especially the water tank, simulating a situation where the electrolyzed water in the water tank is contaminated with pathogens. Next, the hydrogen generator is turned on and kept running, and the amount of microorganisms in the gas output from the outlet of the hydrogen generator is measured.

[0077] In the above experiments, after the hydrogen generator was turned on and operated continuously for 30 minutes to 1 hour, no microorganisms were detected at the outlet. Furthermore, after 23.5 to 24 hours of operation, no microorganisms were still detected at the outlet. In addition, after 24 hours of operation, the total bacterial count in the water tank was reduced by more than 99%. These experimental results, converted to the logarithmic value of microbial elimination by the electrolytic cell, are greater than 6.46, far exceeding the requirement of a logarithmic value of 5 for high-level disinfection in the "Disinfection Technical Specifications". The above experiments demonstrate that the hydrogen generator with pressure relief function of this invention can eliminate even the most difficult-to-eliminate bacteria in the world while maintaining the purity of the output gas, exhibiting excellent disinfection and sterilization effects.

[0078] In the above specific embodiments, although a higher electrolyte concentration in the electrolyzed water results in a higher pH value, which is beneficial for sterilization, an excessively high electrolyte concentration may reduce the efficiency of electrolysis gas production. Therefore, in practice, the electrolyte concentration in the electrolyzed water can be maintained between 0.5% and 15%, and even further between 1% and 3%. This ensures that the electrolyzer and water tank maintain a high pH alkaline environment to achieve excellent disinfection and sterilization effects, while also maintaining high electrolysis gas production efficiency in the electrolyzer.

[0079] Furthermore, in this specific embodiment, the hydrogen-containing gas generated by the electrolysis of water in the electrolyzer 2 enters the gas flow path and is transferred to other units or modules in the hydrogen generation device E, such as the humidification cup. Note that the paths through which the hydrogen-containing gas can flow in the hydrogen generation device E are all part of the gas flow path, which includes the gas flow path formed between the integrated flow channel device, the electrolyzer, and the hydrogen-water cup as described in the aforementioned specific embodiment. The hydrogen generation device E may also include filter cotton disposed in the gas flow path. Therefore, when the hydrogen-containing gas flows through the filter cotton, bacteria within it will be filtered out.

[0080] Please refer to the following: Figure 3 , Figure 5A , Figure 5B , Figure 6A and Figure 6B . Figure 5B Showing according to Figure 5A A schematic diagram of a hydrogen generator E with pressure relief function, excluding a condenser and filter device. Figure 6A This is based on the cross-sectional view along line segment AA in Figure 5. Figure 6B This is based on the cross-sectional view along line segment BB in Figure 5. (See Figure 5.) Figure 6A and Figure 6B As shown, a first valve element 51 and a second valve element 52 are disposed on the integrated flow channel device 3. The first valve element 51 and the second valve element 52 can be two-way solenoid valves and each includes two valve ports. The first valve element 51 and the second valve element 52 can be opened or closed to allow the two valve ports to communicate with or isolate each other. Further, the integrated flow channel device 3 includes a first opening 305, a second opening 306, and a third opening 307. The first opening 305 connects to the humidification chamber 40 and one of the valve ports of the first valve element 51. The second opening 306 and the third opening 307 respectively connect to the two valve ports of the second valve element 52, and respectively connect to the gas passage 41 and the humidification chamber 40. In practice, the other valve port of the first valve element 51 can be connected to an exhaust pipe 55, and the exhaust pipe 55 can pass through the outer casing to connect to the external environment.

[0081] In this specific embodiment, when the electrolytic cell 2 is operating, the first valve element 51 and the second valve element 52 are closed. At this time, the humidification chamber 40 is not connected to the external environment, and the humidification chamber 40 is not directly connected to the containing space 111 of the water tank 1. Therefore, when the electrolytic cell 2 electrolyzes the electrolyzed water to generate hydrogen-containing gas, the hydrogen-containing gas will not flow directly to the humidification chamber 40 of the humidification cup 4 through the gas channel 41 and the second valve element 52, but will flow sequentially through the connecting chamber 42 of the humidification cup 4, the condensation filter device 6, and the foaming rod 43 to the humidification chamber 40. In addition, the hydrogen-containing gas or other gases located in the humidification chamber 40 will not flow to the external environment.

[0082] When the electrolytic cell 2 stops operating, the first valve element 51 and the second valve element 52 open. At this time, the humidification chamber 40 is connected to the external environment through the first valve element 51, and the humidification chamber 40 is connected to the containing space 111 of the water tank 1 through the second valve element 52 and the gas passage 41. Furthermore, since both the first opening 305 and the third opening 307 are connected to the humidification chamber 40 of the humidification cup 4, outside air from the external environment can enter the humidification chamber 40 of the humidification cup 4 through the first valve element 51 and the first opening 305 (e.g., ...). Figure 6A(As indicated by the arrow in the image), and the outside air in the humidification chamber 40 can flow through the third opening 307 to the second valve element 52, and then through the second opening 306 through the gas passage 41 and into the containment space 111 of the water tank 1 (as shown by the arrow in the image). Figure 6B (As indicated by the arrow in the diagram). In this specific embodiment, when the electrolytic cell 2 stops operating, the accommodating space 111, the gas passage 41, the second valve element 52, the humidification chamber 40, and the first valve element 51 form a continuous channel to allow outside air to enter.

[0083] In practice, when the electrolyzer 2 of the hydrogen generator E with pressure relief function is operating, the working temperature of the electrolyzer 2 will gradually rise, and the temperature of the water tank 1 will also rise accordingly. Furthermore, when the electrolyzer 2 stops operating, its working temperature will gradually decrease, causing the gas pressure in the water tank 1 to drop and creating a negative pressure. At this time, the replenishment water in the humidification cup 4 will enter the foaming rod 43 through the micro-bubble structure and flow to the integrated flow channel device 3. Then, it will flow through the condensation flow channel 61 and into the condensation filter device 6. Finally, it will enter the water tank 1 from the condensation filter device 6 through the connecting chamber 42. The replenishment water in the humidification cup 4, when passing through the condensation filter device 6, also flushes the electrolyte filtered by the condensation filter device 6 back into the water tank 1.

[0084] However, because the pore size of the micro-bubble structure of the foaming rod 43 is very small, the volume of the replenished water or gas in the humidification cup 4 that passes through the micro-bubble structure of the foaming rod 43 is also small. Furthermore, the pore size of the micro-bubble structure of the foaming rod 43 is much smaller than the size of the water tank 1. Therefore, when the gas pressure in the water tank 1 generates negative pressure due to the decrease in the working temperature of the electrolytic cell 2, part of the negative pressure can only flush the replenished water in the humidification cup 4 back to the water tank 1 through the foaming rod 43. The remaining negative pressure will cause the water tank to deform or break because it cannot be released and balanced immediately. Alternatively, the negative pressure in the water tank 1 will continue to flush the replenished water in the humidification cup 4 back to the water tank 1, causing the water level in the water tank 1 to be too high, resulting in excessive pressure and breakage. Or, the negative pressure in the water tank 1 will cause the drinking water in the hydrogen water cup 8 to flow back into the water tank 1 through the inlet air passage 301 and the foaming rod 43, thereby contaminating the electrolyzed water.

[0085] The hydrogen generating device E with pressure relief function of the present invention opens the first valve element 51 and the second valve element 52 when the electrolyzer 2 stops operating. At this time, the negative pressure in the water tank 1 will cause the gas in the humidification chamber 40 to flow through the second valve element 52 and the gas passage 41 to the accommodating space 111 of the water tank 1, and will also cause the outside air in the external environment to flow through the first valve element 51 to the humidification chamber 40 of the humidification cup 4, so that the pressure in the water tank 1 and the pressure in the external environment are balanced. This not only avoids the deformation or cracking of the water tank 1 caused by the pressure difference that cannot be immediately balanced, but also prevents the replenishment water in the humidification cup 4 from continuously flowing back into the water tank 1 and causing the water level in the water tank 1 to be too high, and also prevents the drinking water in the hydrogen water cup 8 from flowing back into the water tank 1, thereby improving safety and electrolysis efficiency.

[0086] In practice, when the electrolytic cell 2 stops operating, the first valve element 51 and the second valve element 52 can be opened only after a certain interval. The negative pressure generated in the water tank 1 during the interval can be used to flush the electrolyte in the condensation channel 61 back to the water tank 1 through the foaming rod 43 with the replenished water in the humidification cup 4.

[0087] The positions of the first and second valve elements can be as described in the aforementioned embodiments, or other configurations. In one embodiment, the first valve element is positioned on the humidification cup, and the second valve element is positioned in the gas channel. In practice, the water level in the humidification cup can be 80% to 90% of the height of the humidification chamber. The first valve element can be positioned at the upper edge of the outer wall of the humidification cup to connect the humidification chamber with the external environment. Furthermore, the other end of the gas channel connecting the water tank's accommodating space can also be directly connected to the upper edge of the humidification cup, with the second valve element positioned in the gas channel. Therefore, when the electrolytic cell 2 stops operating, the first and second valve elements open. At this time, the first valve element allows outside air to be directly introduced into the humidification chamber, and the outside air in the humidification chamber can flow through the gas channel and the second valve element into the accommodating space of the water tank. In addition, the second valve element can also be positioned on the water tank and connect the accommodating space of the water tank with the gas channel.

[0088] In one specific embodiment, the hydrogen generating device E with pressure relief function may further include a filter (not shown) disposed at the outlet of the hydrogen generating device E with pressure relief function, for filtering microorganisms in the hydrogen-containing gas at the outlet, or killing bacteria in the hydrogen-containing gas. The components of the filter may include at least one of activated carbon, nano-silver sputtering, polyethylene terephthalate (PET), and polypropylene (PP) fiber cloth. The antibacterial type may include Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and drug-resistant Staphylococcus aureus, but is not limited to these. In practice, the outlet 71 may be the outlet of the nebulizer 7. When the hydrogen-containing gas and the atomized gas are mixed to form a health gas, the filter can first filter the germs in the health gas flowing through the outlet 71 before it is inhaled by the user. In one specific embodiment, the air outlet can be an air outlet pipe that directly provides hydrogen-containing gas or a mixed gas. The filter can first filter the germs in the hydrogen-containing gas or mixed gas flowing through the air outlet pipe before allowing the user to inhale it. In another specific embodiment, the air outlet can also be the outlet of the air outlet pipe connected to the first valve element. When the first valve element is open, the filter can first filter the germs in the outside air entering the air outlet pipe before allowing the outside air to flow through the first valve element to the humidification chamber of the humidification cup. It should be understood that those skilled in the art can add multiple filters and adjust their positions as needed.

[0089] The aforementioned filter can be of different forms, installed at different locations on the hydrogen generating device E or located outside the hydrogen generating device E. In one specific embodiment, the hydrogen generating device E may include an ozone generator, which is coupled to the gas flow path for hydrogen-containing gas flow formed between the integrated flow channel device, the electrolyzer, and the hydrogen water cup. When the electrolyzer stops electrolyzing, the ozone generator can produce ozone to enter the gas flow path for sterilization and disinfection. Thus, when the electrolyzer restarts, the gas flow path has been cleaned and is in a sterile or minimally pathogenic state, so the hydrogen-containing gas generated by the electrolyzer will not be contaminated by pathogens in the gas flow path. Furthermore, the ozone generator can also be coupled to the liquid flow path for water supply to provide ozone for disinfection of the liquid flow path.

[0090] The ozone generator can be installed inside or outside the hydrogen generating unit E. In practice, the hydrogen generating unit E may have a housing to accommodate the aforementioned units, and the ozone generator may be coupled via a delivery pipe to the gas flow path for hydrogen-containing gas flow formed between the integrated flow channel device, electrolyzer, and hydrogen water cup within the hydrogen generating unit E, or coupled to the liquid flow path. Therefore, when the electrolyzer stops electrolyzing, the ozone generator outside the hydrogen generating unit E can generate ozone, and the gas flow path or liquid flow path within the hydrogen generating unit E can receive the ozone via the delivery pipe to sterilize and disinfect the gas flow path or liquid flow path.

[0091] In one specific embodiment, the hydrogen generator E with pressure relief function may further include an ultraviolet light source (not shown) disposed within the hydrogen generator E to emit ultraviolet light to eliminate microorganisms in the hydrogen-containing gas, or to kill bacteria in the hydrogen-containing gas. The ultraviolet light source may emit short-wave ultraviolet light (UV-C) with a wavelength between 100nm and 280nm to sterilize the gas. In practice, the ultraviolet light source may be disposed in the atomizer 7 to emit ultraviolet light and sterilize the health-care gas, but it is not limited thereto. The ultraviolet light source may also be disposed in the water tank 1, the integrated flow channel device 3, the humidification cup 4, or any pipeline through which the hydrogen-containing gas flows to emit ultraviolet light to sterilize these components and devices. In addition, the ultraviolet light source may also be disposed in a continuous channel. When outside air flows from the external environment into the hydrogen generator E with pressure relief function, the ultraviolet light source may also emit ultraviolet light to sterilize the outside air in the continuous channel. In practice, the ultraviolet light source can be placed at any position in the gas or water transmission path of the hydrogen generator E with pressure relief function to sterilize the transmission path and the gas and water therein. Therefore, in addition to achieving sterilization through alkaline electrolyzed water in the water tank and the operating temperature of the electrolyzer, the hydrogen generator with pressure relief function of the present invention can also be further sterilized by using a filter or ultraviolet light source to enhance the sterilization effect and thus improve safety.

[0092] In one specific embodiment, the hydrogen generating device E with pressure relief function further includes a flame arrester 9 coupled to the first valve element 51. The flame arrester 9 may include at least one of a metal mesh filter element and a corrugated filter element, capable of preventing the intense flame of deflagration and withstanding corresponding mechanical and thermal effects. The flame arrester 9 can be used to block the flow of the fire source through the flame arrester 9 to prevent the fire from spreading from one side of the flame arrester 9 to the other side, causing the fire to spread through the gas flow channel and explode. In this specific embodiment, the flame arrester 9 is disposed on the gas outlet pipe 55 connected to the first valve element 51.

[0093] In practice, when electrolyzer 2 is operating, the hydrogen-containing gas produced by electrolyzing water in electrolyzer 2 of water tank 1 flows not only through the connecting chamber 42 but also to the gas channel 41. Furthermore, besides being filtered and humidified by the replenishing water in the humidification chamber 40 through the foaming rod 43, some of the hydrogen-containing gas also remains in the space of the humidification chamber 40. In other words, the continuous channel also contains hydrogen-containing gas. Further, when electrolyzer 2 stops operating and the first valve element 51 and the second valve element 52 are opened, outside air can enter the interior of the hydrogen generator E with pressure relief function through the first valve element 51, and the hydrogen-containing gas in the continuous channel may also flow to the outside environment through the first valve element 51 and the second valve element 52 and the gas outlet pipe 55. Moreover, since the hydrogen-containing gas contains flammable gas components, if the gas in the continuous channel is unfortunately ignited, the flame arrester 9 can prevent the ignited gas from spreading to the outside of the hydrogen generator E with pressure relief function, thereby improving safety. It should be understood that those skilled in the art can add multiple flame arresters and adjust their positions as needed to achieve more zoned and staged flame arrest, and are not limited to this.

[0094] The condensation and filtration device of the hydrogen generation apparatus with pressure relief function of the present invention can be in other forms besides the specific embodiments described above. Please refer to... Figure 7 as well as Figure 8 . Figure 7 A schematic diagram of a hydrogen generation device E' with a pressure relief function according to a specific embodiment of the present invention is shown. Figure 8 The drawing is displayed according to Figure 7 An exploded view of the integrated flow channel device 3' of the hydrogen generation device E' with pressure relief function. The difference between this specific embodiment and the previous specific embodiments is that the condensation filter device 6' in this specific embodiment is fixedly installed in the integrated flow channel device 3'. Figures 7 to 8 As shown, the integrated flow channel device 3' includes an upper cover 31' and a lower cover 32', and the lower cover 32' has a plurality of spacers 320' arranged in a specific manner. When the upper cover 31' and the lower cover 32' are combined, a condensation flow channel 33' is formed. Further, the hydrogen generating device E of the present invention may have a plurality of filter cottons 35'. The filter cottons 35' may be disposed in the condensation flow channel 33' for preliminary filtration of impurities in the hydrogen-containing gas. The aforementioned spacers 320' can be used to separate the plurality of filter cottons 35' to avoid overlapping between the filter cottons 35' or mutual moisture absorption due to contact between the filter cottons 35', thereby reducing the condensation and moisture absorption effect. Please note that Figure 7 The functions of the water tank 1', humidification cup 4', atomizer 7' and hydrogen water cup 8' are roughly the same as those of the components corresponding to the aforementioned specific embodiments, and will not be repeated here.

[0095] Please see Figure 9 . Figure 9 A schematic diagram of the appearance of a hydrogen generator E” with a pressure relief function according to a specific embodiment of the present invention is shown. In this specific embodiment, the hydrogen generator E” with a pressure relief function further includes a water inlet (not shown) disposed on an integrated flow channel device and connected to the condenser flow channel of a condenser filter device. In practice, since the water volume in the tank of the hydrogen generator E” with a pressure relief function will gradually decrease after a long reaction period, the user can add water through the water inlet to replenish the water volume in the tank. When the user adds water through the water inlet, the water will flow through the condenser flow channel and the connecting chamber of the condenser filter device and flow to the water tank, and the electrolyte remaining in the condenser flow channel due to the condenser filter device filtering electrolyzed water can also be flushed back into the water tank with the water.

[0096] like Figure 9 As shown, the water inlet of the hydrogen generator E” with pressure relief function can also be directly connected to a water tank 8”, and the hydrogen generator E” with pressure relief function can directly replenish the water in the water tank through the replenishment water in the water tank 8”. In this specific embodiment, the hydrogen generator E” with pressure relief function further includes a housing 100” for accommodating the water tank, electrolytic cell, integrated flow channel device, condenser filter device, humidification cup, hydrogen water cup, and atomizer. The water tank 8” is disposed outside the housing 100” and is used to provide replenishment water so that the replenishment water flows through the condenser flow channel of the condenser filter device to the water tank. In practice, the hydrogen generator E” with pressure relief function may further include a controller and a control valve (not shown), and the controller is coupled to the control valve. The control valve may be disposed at the water inlet, and the controller may be used to control the opening and closing of the control valve to control the water flow in the water tank 8” to the water inlet. In addition, the hydrogen generating device E” with pressure relief function may further include a water tank bracket 81” disposed on the housing 100” and used to support the water tank 8”, thereby increasing stability and safety.

[0097] In summary, the hydrogen generator with pressure relief function of the present invention allows for the introduction of outside air to balance the pressure in the water tank when the electrolyzer is not operating, through the opening of the first and second valve elements, thus preventing the water tank from deforming due to pressure differences and improving safety. Furthermore, the hydrogen generator with pressure relief function of the present invention can prevent other liquids from flowing back into the water tank, thereby contaminating the electrolyzed water or causing the water level in the tank to become too high, leading to excessive pressure and rupture, thus improving electrolysis efficiency and safety. Moreover, the hydrogen generator with pressure relief function of the present invention can also continuously perform self-disinfection and self-sterilization through alkaline electrolysis environments, temperature environments unfavorable to bacteria or bacteria survival, and various devices such as filters, ultraviolet light sources, and ozone generators. In addition to providing users with germ-free, pure hydrogen-containing gas or health-promoting gas, it can also significantly reduce the maintenance costs of the hydrogen generator. Furthermore, the hydrogen generator with pressure relief function of the present invention can also prevent electrolyte from flowing into the humidification chamber and maintain the electrolyte concentration in the electrolyzed water by using an external water tank to backflush the electrolyte and a baffle plate assembly, thereby maintaining electrolysis efficiency. In addition, the hydrogen generator with pressure relief function of the present invention can also have a flame arrester installed on the continuous channel to prevent the spread of accidentally ignited gas to the outside of the hydrogen generator, thereby improving safety.
