Its application value in daily health care and management is gradually being recognized, leading to its increasing popularity among consumers and a sustained growth in market demand for related hydrogen water preparation products. Currently, existing hydrogen water preparation devices are mainly based on electrolysis technology, generating hydrogen through an electrolytic reaction and dissolving it in water to produce hydrogen-rich water. However, the existing hydrogen water preparation devices have significant limitations in their structural design. Their operation generally relies on the connection of a specific water cup. Users need to first fill the special water cup with purified water, and then assemble and fix the electrolysis components and connecting parts of the hydrogen water preparation device to the water cup before starting the preparation process. Each operation is cumbersome and time-consuming, which not only increases the burden on users, but also affects the efficiency of the electrolysis reaction due to problems such as poor sealing and poor contact during the assembly process.

[0021] Hydrogen-rich water contains hydrogen, which has numerous positive physiological effects, including regulating the body's internal environment, enhancing immune function, and improving overall health. Its application value in daily health care and management is gradually being recognized, leading to its increasing popularity among consumers and a sustained growth in market demand for related hydrogen water preparation products. Currently, existing hydrogen water preparation devices are mainly based on electrolysis technology, generating hydrogen through an electrolytic reaction and dissolving it in water to produce hydrogen-rich water. However, the existing hydrogen water preparation devices have significant limitations in their structural design. Their operation generally relies on the connection of a specific water cup. Users need to first fill the special water cup with purified water, and then assemble and fix the electrolysis components and connecting parts of the hydrogen water preparation device to the water cup before starting the preparation process. Each operation is cumbersome and time-consuming, which not only increases the burden on users, but also affects the efficiency of the electrolysis reaction due to problems such as poor sealing and poor contact during the assembly process. This results in a long preparation cycle for a single batch of hydrogen-rich water and low overall production efficiency, which cannot meet users' needs for convenient and efficient hydrogen-rich water preparation and limits the promotion and application of hydrogen-rich water preparation devices.

[0022] To overcome the above technical problems, refer to Figures 1-3 This application provides a hydrogen water generator, comprising: A mixing tank 1 is connected to an inlet pipe 11 and an outlet pipe 12, and a tank opening is provided at the lower end of the mixing tank 1; Electrolysis module 2 is used to electrolyze water to produce hydrogen. The electrolysis module 2 is connected to the lower end of the mixing tank 1 and is connected to the inner cavity of the mixing tank through the tank opening. The first inlet of the inlet pipe 11 is used to connect to an external water source pipe, and the first outlet of the inlet pipe 11 is located near the electrolysis module 2 at the lower end of the mixing tank 1; the second inlet of the outlet pipe 12 is connected to the top of the mixing tank 1, and the second outlet of the outlet pipe 12 is used to connect to an external return water pipe.

[0023] In the structure of the hydrogen-water generator in this embodiment, the mixing tank 1 serves as the core cavity for the preparation and mixing of hydrogen-rich water. The lower end of the tank is provided with a tank opening to provide a channel for the installation of the electrolysis module 2 and the initial mixing of hydrogen and water. The inside of the tank forms a sealed space, which can create a certain high-pressure environment during operation, providing the necessary conditions for the efficient dissolution of hydrogen in water. At the same time, the tank is connected to the inlet pipe 11 and the outlet pipe 12 in a through-type connection to ensure the continuous circulation of water and the stable output of hydrogen-rich water.

[0024] Electrolysis module 2, as the core component for hydrogen generation, is connected to the lower end of mixing tank 1 and communicates with the inner cavity of the tank through the tank opening. This allows the hydrogen generated by electrolysis to directly enter the water body, avoiding leakage of hydrogen during the transmission process and improving hydrogen utilization. Electrolysis module 2 is installed at the bottom of the tank, which conforms to the physical property of hydrogen floating, laying the foundation for the full mixing of hydrogen and water.

[0025] The first inlet of the water inlet pipe 11 is used to connect to the water source pipe of the external water purification system to ensure a continuous supply of pure water; the first outlet is located near the electrolysis module 2 at the lower end of the mixing tank 1, so that the water can directly act on the electrolysis area. On the one hand, it can remove the heat generated by the electrolysis module 2 during operation in a timely manner to ensure the stable operation of the electrolysis module 2. On the other hand, it can form an upward water flow thrust to provide power for the discharge of hydrogen-rich water.

[0026] The second inlet of the outlet pipe 12 is connected to the top of the mixing tank 1. Since hydrogen will form a high-concentration hydrogen-rich water area in the upper part of the tank after it floats up, the top water intake can ensure that the output hydrogen-rich water has a stable hydrogen content. The second outlet is used to connect to the external return water pipe, water storage tank or faucet to realize the direct use or storage of hydrogen-rich water, which can meet the needs of different usage scenarios.

[0027] In this embodiment, the hydrogen water generator can be integrated into a household or commercial water purification system. The first inlet of the inlet pipe 11 is connected to an external pure water source pipe, and the second outlet of the outlet pipe 12 is connected to a water storage tank or faucet according to usage requirements, thus completing the system setup. After startup, the water source pipe continuously supplies pure water to the inlet pipe 11, and the water flow is continuously injected into the mixing tank 1 through the first outlet (near the electrolysis module 2). After the electrolysis module 2 is powered on, the electrolysis reaction is initiated, decomposing the pure water injected into the bottom of the tank to produce hydrogen gas. The hydrogen gas naturally floats because its density is less than that of water. Since the mixing tank 1 is a closed structure, the continuous injection of water and the rising hydrogen gas work together to create a certain high-pressure environment inside the tank. The high-pressure conditions significantly increase the solubility of hydrogen gas in water. During the rising process, the hydrogen gas fully contacts and mixes with the continuously flowing water, gradually forming a uniform and stable hydrogen-rich water. The inlet pipe 11 continuously injects pure water into the bottom of the tank, creating an upward water pressure. This pressure pushes the prepared hydrogen-rich water in the upper part of the tank to flow to the top and enters the outlet pipe 12 through the second inlet. The hydrogen-rich water is then transported to the storage tank via the outlet pipe 12 or discharged directly through a tap, enabling users to access the hydrogen-rich water immediately. The entire process requires no manual intervention, forming a continuous cycle of "water inlet - hydrogen production - mixing - water outlet".

[0028] The hydrogen water generator of this application, through structural optimization and system integration design, effectively solves the problems of limited application scenarios, cumbersome operation, and low production efficiency of existing hydrogen water preparation devices, and has significant technical advantages: it can be directly integrated into household or commercial water purification systems without relying on special water cups, breaking through the limitations of fixed locations and adapting to multiple scenarios such as daily drinking, kitchen cooking, and office hydration; it adopts a combination of continuous water supply and electrolytic hydrogen production, eliminating the need for manual repetitive operations such as filling water, assembling, and disassembling, simplifying the usage process and reducing user costs. The sealed structure of the mixing tank 1 creates a high-pressure environment, which, combined with the synergistic effect of hydrogen flotation and continuous water flow, significantly improves the dissolution efficiency and uniformity of hydrogen in water, ensuring that the output hydrogen-rich water has a stable hydrogen content. At the same time, the design of the water inlet pipe 11 close to the water outlet of the electrolysis module 2 not only ensures the heat dissipation effect of the electrolysis module 2, but also provides power for the continuous discharge of hydrogen-rich water, realizing the continuous preparation and immediate use of hydrogen-rich water, significantly improving the preparation efficiency and user experience, and facilitating the promotion and application of hydrogen-rich water preparation technology in home and commercial scenarios.

[0029] In one embodiment, reference is made to Figure 4 and Figure 5The water inlet pipe 11 includes an outer pipe body 111 and an inner pipe body 112. The outer pipe body 111 is integrally formed on the top of the mixing tank 1. The inner pipe body 112 is installed inside the mixing tank 1 and connected to the inner end of the outer pipe body 111. The end of the inner pipe body 112 away from the outer pipe body 111 is the first water outlet, which extends downward to be close to the electrolysis module 2 at the bottom.

[0030] The outer pipe body 111 serves as the connection carrier between the inlet pipe 11 and the external water source pipe. It is integrally formed on the top of the mixing tank 1, forming a seamless structural connection with the mixing tank 1 without the need for additional seals or fasteners, resulting in a strong overall structure. The outer end of the outer pipe body 111 forms the first water inlet for connecting to the water source pipe of the external water purification system, while the inner end forms a detachable or fixed connection with the inner pipe body 112, providing a channel for water flow into the inner pipe body 112. The inner pipe body 112, as the core component for water flow guidance, is installed inside the mixing tank 1 using a post-assembly method. Its upper end precisely connects with the inner end of the outer pipe body 111 (fixed through threaded connection, snap-fit ​​connection, or interference fit, etc.), and its lower end extends downwards as the first water outlet to the area near the bottom of the electrolysis module 2 of the mixing tank 1. The length and installation position of the inner pipe body 112 are precisely designed to ensure that the first water outlet can be aligned with the electrolysis area of ​​the electrolysis module 2, achieving directional water flow.

[0031] Pure water from the external water source enters the inlet pipe 11 through the first inlet of the external pipe body 111. Since the external pipe body 111 is integrally formed with the mixing tank 1, there is no risk of leakage during the water flow, ensuring water supply efficiency. The water flows through the external pipe body 111 to the inner pipe body 112. The inner pipe body 112 guides the water flow from the top of the mixing tank 1 to the vicinity of the bottom electrolysis module 2 through a downward extending structure, realizing directional transportation of "top water inlet and bottom water outlet".

[0032] This embodiment designs the water inlet pipe 11 as a separate structure of an outer pipe body 111 and an inner pipe body 112. While ensuring the core hydrogen production and water supply functions of the hydrogen water generator, it further improves the reliability, ease of processing, and stability of use of the product. The design of the outer pipe body 111 and the mixing tank 1 as an integral part completely eliminates the risk of leakage at the connection, improves the reliability and sealing of the structural connection, and ensures the stability of the water supply process. The inner pipe body 112 adopts a post-assembly form, which not only simplifies the overall molding process of the mixing tank 1 and reduces the difficulty of mold design and demolding, but also helps to improve production efficiency and control manufacturing costs. Furthermore, by flexibly adjusting the length and installation position of the inner pipe body 112, it can be adapted to mixing tanks 1 and electrolysis modules 2 of different specifications, thereby enhancing the versatility and adaptability of the product.

[0033] In one embodiment, the water outlet pipe 12 is integrally formed on the top of the mixing tank 1.

[0034] The one-piece molding process eliminates the splicing gaps at the connection between the water outlet pipe 12 and the mixing tank 1, which not only significantly improves the structural sealing performance, effectively preventing hydrogen-rich water leakage and hydrogen escape, and ensuring the stability of the hydrogen content of the hydrogen-rich water, but also enhances the load-bearing capacity and durability of the overall structure, extending the product's service life. At the same time, it eliminates the need for additional connecting parts and assembly processes, simplifying the overall structural design and production process of the product, reducing the difficulty of mold development, assembly costs, and defect rates during production, which is conducive to achieving large-scale production.

[0035] In one embodiment, reference is made to Figure 1 The side wall of the mixing tank 1 is provided with a mounting base 13, which is adapted to be fixed on a support in the installation environment.

[0036] The mounting base 13 is integrally formed or fixedly connected to the side wall of the mixing tank 1 (it can be set in the middle, upper middle or other stress-balanced areas of the tank according to installation requirements). Its structural form is adapted to the type of support in the installation environment. If the support is a planar structure such as a wall or equipment bracket, the mounting base 13 can be designed as a flat plate structure with bolt holes; if the support is a tubular or frame structure, the mounting base 13 can be designed as a clamp or snap-fit ​​structure to ensure a stable fit with the support. The connection strength between the mounting base 13 and the mixing tank 1 has been mechanically optimized to withstand the overall weight of the hydrogen-water generator during operation (including the weight of the tank, water flow, electrolysis module 2 and other components) and the vibration generated during operation, avoiding problems such as loosening or displacement after installation. At the same time, the setting of the mounting base 13 does not affect the connection relationship between the mixing tank 1 and the inlet pipe 11, outlet pipe 12 and electrolysis module 2, nor does it interfere with the water flow and hydrogen mixing process in the inner cavity of the tank.

[0037] Mounting bracket 13 provides a standardized fixed interface for the hydrogen water generator, which can be quickly adapted to various supports of household or commercial water purification systems without the need for additional customized installation structures, simplifying the installation process and reducing installation difficulty and labor costs.

[0038] In one embodiment, combined with Figure 3 and Figure 7 It also includes a cylindrical adapter 3, which is provided with an internal thread. The threaded connector 2111 of the electrolysis module 2 extends into the adapter 3 and connects with the internal thread. The inner wall of the adapter 3 is also provided with a plurality of first limiting protrusions 311 in a circumferential manner. The outer wall of the mixing tank 1 is provided with second limiting protrusions 14 that correspond one-to-one with the first limiting protrusions 311. The adapter 3 is restricted from axial separation relative to the mixing tank 1 by the cooperation of the first limiting protrusions 311 and the second limiting protrusions 14.

[0039] The adapter 3 has an overall cylindrical structure with internal threads on its inner wall for threaded engagement with the threaded connector 2111 of the electrolysis module 2. It utilizes the standardized thread structure of the existing electrolysis module 2 to achieve quick docking without requiring structural modifications to the electrolysis module 2. Several first limiting protrusions 311 are evenly distributed around the inner wall. The protrusions are block-shaped or strip-shaped, and their axial thickness can be flexibly designed according to the stress requirements. The protrusions are also pre-reserved with notches corresponding to the second limiting protrusions 14 of the mixing tank 1 to provide guidance for assembly.

[0040] The outer wall of the mixing tank 1 is provided with a second limiting protrusion 14 that matches the number and size of the first limiting protrusion 311 at the installation position of the adapter 3. The second limiting protrusion 14 is distributed along the circumference of the tank body, and its axial height is adapted to the axial length of the adapter 3 to ensure that it can form a reliable axial limit after cooperating with the first limiting protrusion 311, thus preventing the adapter 3 from falling off. The hollow threaded connector 2111 of the electrolysis module 2 extends into the adapter 3 and forms a sealed connection with the internal thread of the adapter 3. The through hole of the threaded connector 2111 ensures that the water in the mixing tank 1 can directly contact the internal structure of the electrolysis module 2, ensuring the normal progress of the electrolysis reaction. At the same time, the existing thread design of the electrolysis module 2 is used, reducing the adaptation cost.

[0041] The adapter 3 achieves a reliable connection between the mixing tank 1 and the electrolysis module 2 through a dual fixing method of threaded connection and limiting protrusion engagement. First, the threaded connector 2111 of the electrolysis module 2 engages with the internal thread of the adapter 3 to form a radial seal and fixation, ensuring no relative displacement between the electrolysis module 2 and the adapter 3 and preventing water or hydrogen leakage. Second, after the adapter 3 is inserted into the mixing tank 1 through the notch aligned with the second limiting protrusion 14, the adapter 3 is rotated so that the first limiting protrusion 311 and the second limiting protrusion 14 overlap axially. The axial blocking effect of the protrusions restricts the adapter 3 from separating axially from the mixing tank 1, forming a double insurance to ensure connection stability. During the specific assembly, first screw the threaded connector 2111 of the electrolysis module 2 into the internal thread of the adapter 3 to achieve a sealed connection between the electrolysis module 2 and the adapter 3; then, put the adapter 3 on the lower end of the mixing tank 1 so that the first limiting protrusion 311 enters the assembly position through the notch between the second limiting protrusion 14; then rotate the adapter 3 until the protrusions overlap to complete the limiting and fixing of the adapter 3 and the mixing tank 1.

[0042] In this embodiment, on the one hand, the adapter 3 serves as the internal thread setting component, avoiding the need to directly machine the internal thread at the mouth of the mixing tank 1. This eliminates the need to thicken the overall wall of the mixing tank 1 to ensure connection strength, effectively reducing tank material costs. Simultaneously, the adapter 3 can be machined separately, facilitating control of the internal thread dimensional accuracy and improving the sealing and reliability of the connection. On the other hand, the cooperative design of the first limiting protrusion 311 and the second limiting protrusion 14 not only ensures axial limiting strength by increasing the axial thickness of the protrusions but also simplifies the assembly process. No additional fasteners are required; installation can be completed in just three steps: alignment, insertion, and small-angle rotation, improving assembly efficiency. Furthermore, the adapter 3 enables flexible adaptation between the existing standardized electrolysis module 2 and the mixing tank 1. It utilizes the threaded connector 2111 already provided with the electrolysis module 2, reducing product development and adaptation costs. The dual-fixing structure ensures connection stability during operation, preventing leakage due to vibration and other factors, further guaranteeing the continuity and safety of hydrogen-rich water preparation.

[0043] In one embodiment, reference is made to Figure 2 and Figure 3 The outer wall of the mixing tank 1 is provided with a sealing groove 15, and a first sealing ring 16 is fitted at the sealing groove 15. The inner wall of the adapter 3 abuts against the first sealing ring 16.

[0044] A sealing groove 15 is formed on the outer wall of the mixing tank 1 and located below the second limiting protrusion 14. The groove is annular and its width and depth are adapted to the cross-sectional dimensions of the first sealing ring 16, ensuring that the sealing ring can be stably embedded and will not fall off. The first sealing ring 16 is made of food-grade elastic sealing material (such as silicone, fluororubber, etc.), and is annular. Its cross-sectional shape (circular, rectangular, etc.) matches the sealing groove 15 and has good compression and rebound performance. After the sealing ring is fitted into the sealing groove 15, its outer diameter is slightly larger than the inner wall diameter of the adapter 3, ensuring an interference fit with the inner wall of the adapter 3 to achieve a sealing effect. After the adapter 3 is fitted into the mixing tank 1, its inner wall is tightly abutting against the first sealing ring 16. The elastic compression of the sealing ring fills the tiny gap between the adapter 3 and the mixing tank 1, forming a radial sealing barrier to block the path of water or hydrogen leakage from the gap between the two.

[0045] In one embodiment, reference is made to Figures 6-8 The adapter 3 includes an adapter sleeve 31 and a connecting nut 32. The first limiting protrusion 311 is disposed on the adapter sleeve 31, and the internal thread is disposed on the connecting nut 32. The adapter sleeve 31 is provided with an annular inner shoulder 312, and the threaded connector 2111 of the electrolysis module 2 passes through the inner shoulder 312 to connect to the connecting nut 32.

[0046] The adapter sleeve 31 retains the original first limiting protrusion 311 circumferentially on its inner wall, which cooperates with the second limiting protrusion 14 of the mixing tank 1 to achieve axial limiting. An annular inner shoulder 312 is provided inside the adapter sleeve 31. The inner diameter of the inner shoulder 312 matches the outer diameter of the threaded connector 2111 of the electrolysis module 2, allowing the threaded connector 2111 to pass smoothly through while providing axial support to the electrolysis module 2 through the shoulder end face, limiting excessive screwing into the electrolysis module 2 and ensuring assembly accuracy. The connecting nut 32, as an independent threaded connection component, has an internal thread on its inner wall that matches the threaded connector 2111 of the electrolysis module 2, specifically designed for threaded fixing with the electrolysis module 2. The outer diameter of the connecting nut 32 can be designed according to assembly requirements to ensure a close fit with the end of the adapter sleeve 31, and its axial length matches the engagement depth of the threaded connector 2111, ensuring connection strength.

[0047] During assembly, the threaded connector 2111 of the electrolysis module 2 passes through the inner shoulder 312 from the inside of the adapter sleeve 31 and is screwed into the internal thread of the connecting nut 32 for fixation. The inner shoulder 312 forms an axial limit on the electrolysis module 2, and the connecting nut 32 fits against the end of the adapter sleeve 31. Then, the adapter sleeve 31 is fixed to the lower end of the mixing tank 1 by cooperating with the second limiting protrusion 14 of the mixing tank 1 through the first limiting protrusion 311.

[0048] In this embodiment, modular disassembly enables functional division of labor. The adapter sleeve 31 focuses on limiting and sealing, while the connecting nut 32 focuses on threaded connection. This facilitates the separate control of the machining accuracy of each component (such as the internal thread accuracy of the connecting nut 32 can be optimized independently) and avoids overload on a single component, thereby improving connection stability.

[0049] In one embodiment, reference is made to Figure 7 The electrolysis module 2 includes a module housing 21, and a threaded connector 2111 is disposed on the module housing 21. A second sealing ring 33 is sleeved on the threaded connector 2111, and the two sides of the second sealing ring 33 abut against the module housing 21 and the inner shoulder 312, respectively.

[0050] The second sealing ring 33 is fitted onto the root region of the threaded connector 2111. When the threaded connector 2111 of the electrolysis module 2 passes through the inner shoulder 312 of the adapter sleeve 31 and is screwed and fixed with the connecting nut 32, the second sealing ring 33 is axially clamped between the end face of the module housing 21 and the end face of the inner shoulder 312 of the adapter sleeve 31. Through the squeezing action of the two, elastic deformation is generated, filling the tiny gap between the end faces and forming an axial sealing barrier.

[0051] In one embodiment, reference is made to Figures 9-11The electrolysis module 2 includes a module housing 21 and an electrolysis component 22. The module housing 21 includes a top shell 211 and a bottom cover 212. The electrolysis component 22 is installed between the top shell 211 and the bottom cover 212. The electrolysis assembly 22 includes an anode plate 223, a proton exchange membrane 222, and a cathode plate 221 stacked sequentially. The anode plate 223 includes an anode terminal 2231, and the cathode plate 221 includes a cathode terminal 2211. The anode terminal 2231 and the cathode terminal 2211 extend through the bottom cover 212 respectively. The anode plate 223 is disposed close to the bottom cover 212, and the bottom cover 212 is provided with a waste discharge pipe 2121. The top shell 211 is connected to the bottom of the mixing tank 1. The top shell 211 is provided with a connecting hole that connects the electrolysis component 22 and the inner cavity of the mixing tank 1, so that the electrolysis module 2 can electrolyze water to generate hydrogen and mix it into the water in the mixing tank 1.

[0052] The top shell 211 serves as the connecting carrier between the electrolysis module 2 and the mixing tank 1. It is fixedly connected to the bottom of the mixing tank 1 (via the adapter sleeve 31 and connecting nut 32). A connecting hole is provided on the top shell 211, which is precisely aligned with the opening of the mixing tank 1 to ensure that the hydrogen gas generated by the electrolysis component 22 can directly enter the inner cavity of the mixing tank 1. The top shell 211 and the bottom cover 212 form a sealed cavity, providing a stable installation and working environment for the electrolysis component 22. A waste drain pipe 2121 is provided on the bottom cover 212 to drain the small amount of wastewater generated during the electrolysis reaction (such as residual oxygen-rich wastewater and trace impurities after electrolysis), preventing wastewater accumulation from affecting the electrolysis efficiency. At the same time, the bottom cover 212 has reserved through holes for the anode terminal 2231 and the cathode terminal 2211 to pass through, ensuring the connection between the terminals and the external power supply. The through holes are sealed to prevent water leakage.

[0053] The electrolysis assembly 22 adopts a sandwich-style stacked design of "anode plate 223 + proton exchange membrane 222 + cathode plate 221", with the three components tightly fitted to ensure efficient electrolysis. The anode plate 223 is positioned near the bottom cover 212, and the cathode plate 221 is positioned near the top shell 211, adapting to the upward transport path of hydrogen. The anode plate 223 integrates an anode terminal 2231, and the cathode plate 221 integrates a cathode terminal 2211. Both extend through the bottom cover 212 to the outside for connecting the positive and negative terminals of the power supply, providing electrical energy for the electrolysis reaction. The electrode plates are made of materials with excellent conductivity (such as titanium alloy, platinum-coated electrodes, etc.) to improve electrolysis efficiency and durability. The proton exchange membrane 222 is located between the anode plate 223 and the cathode plate 221. As the core component for ion exchange, it allows hydrogen ions (H+) generated by the decomposition of water molecules to pass through. +The process allows hydrogen and oxygen to mix simultaneously, ensuring that only hydrogen is generated on the cathode plate 221 side, thus improving hydrogen purity. The proton exchange membrane 222 is a self-humidifying proton permeation membrane. Water does not need to be injected into the anode side in advance, and water on the cathode side can permeate through the proton exchange membrane 222 into the oxygen generation chamber to meet the electrolysis requirements.

[0054] In one embodiment, reference is made to Figure 10 and Figure 11 The top shell 211 is provided with a support rib mesh 2112 located in the communicating hole, and the support rib mesh 2112 is provided with a plurality of first support protrusions 2113 for supporting the cathode plate 221; the bottom cover 212 is provided with a plurality of second support protrusions 2122 for supporting the anode plate 223.

[0055] The supporting rib mesh 2112 is integrally formed inside the connecting hole of the top shell 211, and adopts an interlaced rib design (such as Y-shaped, cross-shaped, or grid-shaped), which neither obstructs the flow of water nor hinders the formation of a stable supporting plane. Multiple first supporting protrusions 2113 are provided on the side of the supporting rib mesh 2112 facing the electrolysis assembly 22. The protrusions are hemispherical or cylindrical and evenly distributed on the surface of the rib mesh. Their height is precisely designed to ensure point-contact support with the surface of the cathode plate 221. The second supporting protrusion 2122 is integrally formed on the inner end face of the bottom cover 212 (corresponding to the mounting area of ​​the anode plate 223), also adopting a point-contact design. It works in conjunction with the first supporting protrusions 2113 of the top shell 211 to ensure that the electrolysis assembly 22 is in a precise assembly position after stacking, and that the three maintain a preset contact pressure to avoid gaps.

[0056] When the electrolysis assembly 22 is installed, the lower end face of the anode plate 223 is in close contact with the second support protrusion 2122 of the bottom cover 212, and the upper end face of the cathode plate 221 is in close contact with the first support protrusion 2113 of the support rib mesh 2112 of the top shell 211. Through the bidirectional support and positioning of the two sets of protrusions, the anode plate 223, the proton exchange membrane 222, and the cathode plate 221 form a tightly fitted stacked structure, which not only avoids displacement or tilting during assembly, but also ensures the effective contact area between the electrode and the proton exchange membrane 222, while reserving a small gap for water flow infiltration and reaction product discharge.
