Description

Technical Field

[0001] This utility model relates to the field of electrochemical technology, specifically to a synergistic electrochemical device for hypochlorous acid and hydrogen peroxide. Background Technology

[0002] Hypochlorous acid is a highly efficient and broad-spectrum disinfectant, widely used in tap water and swimming pool disinfection, medical device sterilization, and food processing preservation. Currently, industrially, hypochlorous acid is mainly prepared by electrolysis. The basic principle is to generate free hypochlorous acid through an anodic oxidation reaction in an aqueous solution containing chloride ions (such as tap water or seawater). This method suffers from drawbacks such as low electrolysis efficiency, high energy consumption, and severe equipment corrosion. Hydrogen peroxide, as another strong oxidizing liquid, also possesses excellent bactericidal, disinfecting, and organic matter degradation properties. Industrially, hydrogen peroxide is mostly prepared by electrolysis. The principle is to introduce oxygen onto the cathode surface, causing an electrocatalytic reduction reaction of oxygen to produce H₂O₂. The main limitations of this method are low current efficiency, easy deactivation of the cathode catalyst, and harsh reaction conditions.

[0003] However, when hypochlorous acid and hydrogen peroxide need to be present in solution simultaneously, users must prepare hypochlorous acid and hydrogen peroxide separately before mixing them, which involves cumbersome processes, high costs, and poor synergy. Therefore, it is necessary to develop a synergistic electrochemical device for hypochlorous acid and hydrogen peroxide, which can effectively generate hypochlorous acid and hydrogen peroxide through electrochemical reactions, further meeting users' needs for the simultaneous presence of hypochlorous acid and hydrogen peroxide in solution.

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 6The illustrated electrochemical device for the synergistic generation of hypochlorous acid and hydrogen peroxide includes a housing 1, an inlet 2 and an outlet 3 respectively connected to the housing 1, an electrolyte chamber 4 connected to the inlet 2 and the outlet 3 respectively, a cathode reaction assembly 5, an anode reaction assembly 6 located in the electrolyte chamber 4, and a baffle assembly 7 for increasing the liquid flow path. The cathode reaction assembly 5 is used to generate hydrogen peroxide, and the anode reaction assembly 6 is used to generate hypochlorous acid.

[0025] This invention allows for the direct generation of hydrogen peroxide and hypochlorous acid within the electrolyte chamber via cathode and anodic reaction components, eliminating the need for separate preparation and subsequent mixing. This simplifies the process, reduces costs, and enhances the synergistic effect of hypochlorous acid and hydrogen peroxide. The baffle assembly increases liquid movement, effectively improving mixing and enhancing the efficiency and uniformity of the electrochemical reaction. This invention simplifies the process, reduces costs, and improves operational convenience, meeting users' needs when both hypochlorous acid and hydrogen peroxide are present in the solution.

[0026] Furthermore, as a preferred embodiment of this invention and not a limitation thereof, the housing provides the external structure for the entire electrochemical device, housing the internal components and protecting them from external environmental influences, and providing a closed environment for electrochemical reactions. The housing material is corrosion-resistant and can withstand highly oxidizing environments. An inlet is used to introduce the electrolyte, and an outlet is used to discharge the generated mixture of hydrogen peroxide and hypochlorous acid, ensuring smooth liquid flow and allowing for continuous liquid processing during the electrochemical reaction within the device. The cathode reaction assembly, located within the electrolyte chamber, is used to introduce oxygen onto the cathode surface, generating hydrogen peroxide through the electrocatalytic reduction of oxygen. The anode reaction assembly, also located within the electrolyte chamber, is used to generate hypochlorous acid on the anode surface through the oxidation of chloride ions. A baffle assembly, located within the electrolyte chamber, increases the liquid's movement path and improves hydrodynamic characteristics, thereby increasing reaction efficiency and product uniformity. Compared to traditional methods of stepwise preparation and remixing, this invention is simpler to operate, reduces manual intervention and the use of complex equipment, and lowers maintenance costs and overall expenses.

[0027] Specifically, an external water pump pumps the electrolyte into the electrolyte chamber through the inlet. A redox reaction occurs on the energized electrode surface. Hydrogen peroxide molecules generated by the cathode reaction assembly and hypochlorous acid molecules generated by the anode reaction assembly dissolve in the electrolyte and then flow out of the electrolyte chamber through the outlet. The electrolyte chamber is connected to a container via an outlet pipe. The mixture reacts with the substances to be treated in the container, and the liquid in the container enters the inlet through the inlet pipe and recirculates back into the electrolyte chamber for further reaction.

[0028] This invention utilizes the oxidation reaction of chloride ions in tap water at the anode and the reduction reaction of dissolved oxygen at the cathode to achieve the in-situ synergistic preparation of hypochlorous acid and hydrogen peroxide within the same electrolytic cell. The resulting mixed solution exhibits excellent bactericidal, disinfection, and organic pollutant degradation properties, and can be widely applied in domestic and industrial water treatment, medical and health care, food processing, and other fields.

[0029] like Figures 1 to 5 The diagram illustrates a synergistic electrochemical device for hypochlorous acid and hydrogen peroxide. The cathode reaction assembly 5 includes a cathode electrode 51 and a cathode electrode catalyst, and the anode reaction assembly 6 includes an anode electrode 61 and an anode electrode catalyst. A baffle assembly 7 is located between the cathode electrode 51 and the anode electrode 61. Further, as a preferred embodiment and not a limitation of this invention, the cathode electrode is made of a material with good conductivity and strong chemical stability, such as platinum or a platinum-plated titanium mesh. The cathode electrode catalyst is coated or loaded onto the cathode electrode to lower the activation energy of the cathode reaction and increase the reaction rate. In the preparation of hydrogen peroxide, the cathode electrode catalyst can promote the reduction reaction of oxygen to generate hydrogen peroxide. Cathode electrode catalysts such as ruthenium-based composite oxides can effectively promote the electrolysis of water to generate active oxygen species, which are then converted into hydrogen peroxide, thereby ensuring efficient hydrogen peroxide generation at a lower potential, reducing energy consumption and improving product purity. The anode material is corrosion-resistant and can withstand a high oxidation potential, which is beneficial for the generation of hypochlorous acid, such as a titanium dioxide electrode doped with iridium or ruthenium. Anode electrode catalysts are coated or supported on the anode electrode to lower the activation energy of the anodic reaction and increase the reaction rate. In the preparation of hypochlorous acid, the anode electrode catalyst promotes the oxidation of water molecules, directly generating hypochlorous acid on the anode surface or in the microenvironment, avoiding side reactions and improving the yield of hypochlorous acid.

[0030] Specifically, the baffle assembly is located between the cathode and anode. This assembly increases the liquid's movement path and improves hydrodynamic characteristics, helping to enhance reactant transport efficiency and ensuring effective mixing and synergistic effects of the chemicals produced at the cathode and anode, thus significantly improving the efficiency and uniformity of the electrochemical reaction. This invention provides a novel hypochlorous acid-hydrogen peroxide electrochemical reaction device that is simple in structure, highly efficient and energy-saving, and functionally integrated. Using specially designed anode and cathode materials, it can continuously and stably prepare high-concentration mixed solutions at room temperature and pressure without adding any chemical reagents. By controlling the electrochemical parameters and electrode structure, the concentration ratio of hypochlorous acid to hydrogen peroxide can be flexibly adjusted to meet the needs of different applications.

[0031] Compared with traditional separate preparation, this invention can significantly reduce equipment and operating costs, and improve the performance of sterilization, disinfection and degradation of organic matter.

[0032] During the electrochemical reaction, the electrolyte flows continuously through the electrolyte chamber under the drive of a pump, and hydrogen peroxide is generated by the reduction of dissolved oxygen on the cathode surface.

[0033] O2+ 2H + + 2e - → H2O2E0 = 0.68 V

[0034] Simultaneously, an oxidation reaction of chloride ions occurs on the anode surface to generate hypochlorous acid.

[0035] Cl - + H2O → HClO + H + + 2e - E0 = 1.49 V

[0036] The cathode electrode structure is preferably a plate-like structure, and the electrode material is preferably a high specific surface area such as nickel foam, copper foam, carbon fiber felt, carbon fiber cloth, carbon paper, etc. The electrode surface is loaded with highly active catalysts such as Pt, Pd, and Fe-NC to improve the rate and efficiency of the cathode reduction of O2 to generate H2O2.

[0037] The anode electrode is preferably structured as a plate-like structure or a plate-like mesh structure similar to the cathode electrode. The electrode material is a titanium substrate or a carbon substrate, and the electrode surface is coated with a metal oxide catalyst such as platinum, tin dioxide, or ruthenium / iridium oxide to achieve efficient electrocatalytic oxidation of Cl. - HClO is generated.

[0038] In this process, the H2O2 generated by cathode reduction and the HClO generated by anodic oxidation dissolve in the electrolyte and are thoroughly mixed in the reaction chamber and subsequent pipelines, resulting in the following synergistic bactericidal oxidation reaction:

[0039] HClO + H2O2 → O2 + Cl - + H2O+ •OH

[0040] Under the same acidic conditions, HClO and H2O2 react to release highly oxidizing hydroxyl radicals (•OH). Compared with using HClO or H2O2 alone, the mixed solution significantly enhances the ability to kill pathogenic microorganisms such as bacteria and viruses and to degrade organic pollutants.

[0041] The concentration ratio of hypochlorous acid and hydrogen peroxide in the electrochemical process can be adjusted by controlling the distribution of current at the cathode and anode, so that the ratio and performance of the mixture can be matched with the actual application.

[0042] The hypochlorous acid-hydrogen peroxide mixed solution prepared by this invention can be directly used for disinfection and sterilization of drinking water, sewage, swimming pools, etc., as well as for the degradation of organic pollutants such as dyes and pesticides. Compared with traditional single agents, the synergistic effect of active chlorine and active oxygen in the HClO / H2O2 mixture can multiply the sterilization and degradation effects, and significantly improve the treatment efficiency, making it particularly suitable for situations with high concentrations of microbial contamination and organic pollutants.

[0043] like Figures 2 to 6 The illustrated hypochlorous acid and hydrogen peroxide synergistic electrochemical device includes a baffle assembly 7 comprising a first baffle portion 71 and a second baffle portion 72. A limiting groove 73 for limiting the cathode electrode 51 or the anode electrode 61 is provided between the first baffle portion 71 and the second baffle portion 72. Further, as a preferred embodiment of the present invention and not a limitation thereof, the first baffle portion and the second baffle portion form a physically separated structure, creating a more complex flow path, increasing the turbulence of the liquid on the electrode surface, reducing dead zones, and guiding the electrolyte to flow around the electrode. This increases the contact area and contact time between the electrolyte and the electrode surface, helping the generated hypochlorous acid and hydrogen peroxide to be more effectively removed from the electrode surface and discharged along with the flowing liquid, reducing side reactions and effectively improving the efficiency and rate of the electrochemical reaction. Fluid guidance also helps control temperature and pressure, preventing local overheating or overpressure and improving the safety of the entire device.

[0044] The limiting groove is located between the first and second turbulence sections. This groove not only provides a precise installation position for the cathode or anode electrode, ensuring its stability during electrolysis and preventing displacement or vibration, but also reduces unnecessary electrolyte eddies through its close-fitting design, further minimizing energy loss and ensuring the electrode is securely fixed without affecting the uniform flow of the electrolyte. The limiting groove simplifies the disassembly and replacement of the cathode or anode electrode, allowing it to be easily installed or removed in a preset position, which aids in equipment maintenance.

[0045] like Figures 2 to 6The illustrated device is a synergistic electrochemical apparatus for hypochlorous acid and hydrogen peroxide. The second turbulence section 72 forms a passageway space 74 with the inner wall of the electrolyte chamber 4. The first turbulence section 71 and the second turbulence section 72 are alternately arranged along the extending direction of the cathode reaction assembly 5 or the anode reaction assembly 6. Flow channels 75 for liquid movement are provided between the alternately arranged first turbulence section 71 and second turbulence section 72. Multiple passageway spaces 74 and multiple flow channels 75 form reaction channels 76. Further, as a preferred embodiment of this invention and not a limitation thereof, the passageway space formed by the second turbulence section and the inner wall of the electrolyte chamber not only provides a flow path for the electrolyte but also increases the surface area of ​​the reaction zone, allowing more electrolyte molecules to contact the electrode surface and participate in the reaction. The passageway space forms a "passive stirring" mechanism, maintaining good mass transfer efficiency even at low flow rates. The alternating arrangement of the first and second turbulence sections forms a well-organized network of flow channels and passageway spaces, which can better control the flow direction and speed of the liquid, ensuring thorough mixing and improving reaction efficiency. This layout causes the electrolyte to undergo a complex three-dimensional flow pattern as it passes through the device, forming a series of baffles and reflux zones, which increases the degree of turbulence, helps to eliminate dead zones, and makes the reaction more uniform and thorough.

[0046] The combination of multiple passageways and flow channels creates a highly interactive reaction channel system, allowing the electrolyte to repeatedly approach the electrode surface as it traverses these channels. This promotes reactant conversion and accelerates product diffusion, contributing to increased reaction rates and more uniform product distribution. It also facilitates timely heat dissipation, maintaining the stable operation of the electrochemical device. The first and second turbulence sections effectively control the electrolysis environment, reduce side reactions, and improve the yield and purity of the target products, hypochlorous acid and hydrogen peroxide.

[0047] like Figures 2 to 6 The illustrated device is a synergistic electrochemical apparatus for hypochlorous acid and hydrogen peroxide. The first turbulence section 71 has a wider extension than the second turbulence section 72, and the reaction channel 76 is arranged in an "arch" shape. Further, as a preferred embodiment of this invention and not a limitation thereof, the wider extension of the first turbulence section than the second turbulence section effectively controls the speed and direction of liquid flow, ensuring thorough mixing of the liquid in the reaction channel. The wider first turbulence section slows down the electrolyte flow rate, providing longer contact time and a larger mass transfer area, which is beneficial for enhancing the reactivity of the cathode or anode surface. The narrower second turbulence section forms a passageway with the inner wall of the electrolyte chamber, facilitating electrolyte flow, promoting continuous replenishment of new electrolyte and rapid removal of products, and avoiding side reactions or catalyst poisoning caused by excessively high local concentrations. By controlling the speed and direction of liquid flow, thorough mixing of the liquid in the reaction channel is ensured.

[0048] The bow-shaped reaction channel creates a non-linear path, increasing the meandering path of the electrolyte around the electrodes and expanding the effective surface area of ​​contact between the electrolyte and electrodes. This not only enhances the mixing of the electrolyte and electrode surfaces but also generates stronger turbulence, reducing dead zones in the liquid flow and allowing the reaction medium to be more uniformly exposed to the electrochemically active regions, thereby improving reaction uniformity and overall efficiency. Simultaneously, this design also helps reduce energy loss, as turbulence effectively reduces the resistance formed during electrolysis.

[0049] like Figures 2 to 6 The diagram illustrates a synergistic electrochemical device for hypochlorous acid and hydrogen peroxide. The cathode electrode 51 and the anode electrode 61 are located on opposite sides of a reaction channel 76. The cathode electrode 51 is located away from the liquid inlet 2, and the anode electrode 61 is located closer to the liquid inlet 2. The liquid inlet 2 is located on one side of the reaction channel 76, and the liquid outlet 3 is located on the other side of the reaction channel 76. Further, as a preferred embodiment of this invention and not a limitation thereof, the cathode electrode and anode electrode are located on opposite sides of the reaction channel. This arrangement facilitates effective separation and reaction during electrolysis.

[0050] Optionally, in some embodiments, when the coverage area of ​​the cathode electrode is larger than that of the anode electrode, the cathode electrode is farther away from the inlet relative to the anode electrode. When the electrolyte enters the electrolyte chamber directly from the inlet, the cathode electrode can preferentially contact the fresh electrolyte, which helps to initiate the reduction reaction to generate hydrogen peroxide. Although the anode electrode is close to the inlet, it requires the liquid to react with the cathode electrode first or to fill the electrolyte chamber before reacting with the anode electrode. This helps to reduce the impact of oxygen generated at the anode on the cathode reaction. This design is beneficial for maintaining the stability and continuity of the chemical reaction within the channel.

[0051] Placing the inlet and outlet on different sides of the reaction channel ensures that the fully electrolyzed liquid can be discharged smoothly, which helps to avoid blockage problems caused by deposits or bubbles, thereby improving the reliability and continuity of the device.

[0052] like Figures 3 to 5 The device shown is a synergistic electrochemical device for hypochlorous acid and hydrogen peroxide. The housing 1 includes a first housing 8 and a second housing 9. The liquid inlet 2 and the liquid outlet 3 are both located on the first housing 8. The first housing 8 is provided with a first housing mounting part 80, and the second housing 9 is provided with a second housing mating part 90. The first housing mounting part 80 and the second housing mating part 90 are connected to each other so that the first housing 8 and the second housing 9 enclose the electrolyte chamber 4.

[0053] Furthermore, as a preferred embodiment of this utility model and not a limitation, the first and second shells are connected together to form an electrolyte chamber. This structural design makes the electrolyte chamber more stable, tight, and reliable, providing a closed and safe environment for the electrochemical reaction, ensuring the normal operation of the equipment and the efficient conduct of the chemical reaction. The modular design makes the device easy to assemble and disassemble, facilitating maintenance. When cleaning or inspection of the electrolyte chamber is required, the split design allows for easy separation of the shells, enabling direct contact with the interior of the chamber for thorough cleaning or component replacement, which is crucial for maintaining long-term efficient operation and extending the service life of the system. Both the inlet and outlet are located on the first shell; this layout facilitates the flow of liquid within the electrolyte chamber along a specific path, thereby improving reaction efficiency.

[0054] Optionally, in some embodiments, the first housing mounting part and the second housing mating part can be connected by one or more of the following methods: snap-fit ​​connection, fastener connection, threaded connection, magnetic connection, mortise and tenon connection, groove connection, etc.

[0055] Specifically, in some embodiments, the first housing mounting part is a snap-fit ​​part, and the second housing mating part is a connecting step part, and the connection between the first housing and the second housing is achieved through snap-fit ​​connection.

[0056] like Figures 2 to 6The illustrated hypochlorous acid and hydrogen peroxide synergistic electrochemical device includes a first housing 8 with a first positioning groove 82. The anode electrode 61 has an anode reaction plate 611 connected to the limiting groove 73 and an anode conductive end 612 connected to the anode reaction plate 611 with one end extending to the outside of the first positioning groove 82. The second housing 9 has a second positioning groove 91. The cathode electrode 51 has a cathode reaction plate 511 connected to the inner cavity of the second housing 9 and a cathode conductive end 512 connected to the cathode reaction plate 511 with one end extending to the outside of the second positioning groove 91. Further, as a preferred embodiment of this invention and not a limitation, the first and second positioning grooves ensure stable positioning and electrical connection of the anode and cathode conductive ends. The first and second positioning grooves allow the anode and cathode conductive ends to extend outside the housing, facilitating direct connection to junction boxes or wires in external circuits, simplifying the electrical connection process, while also maintaining the cleanliness and sealing of the internal structure and reducing the risk of electrolyte leakage. The cathode electrode is in close contact with the inner cavity of the second housing via a cathode reaction plate, ensuring the effective conduction of the electrochemical reaction. The cathode reaction plate helps to increase the surface area of ​​the electrochemical reaction, thereby improving the hydrogen peroxide generation efficiency. The cathode conductive end is connected to the cathode reaction plate and passes through the first positioning groove. This arrangement facilitates the electrical connection of the cathode electrode, making electrode replacement and maintenance easier, and also provides stable mechanical support for the electrode, ensuring that the electrode will not shift due to electrolyte flow during the reaction. The anode electrode is fixed by a limiting groove, and the anode reaction plate increases the contact area with the electrolyte, thereby improving the ozone generation efficiency. The anode conductive end is connected to the anode reaction plate and passes through the first positioning groove. This arrangement facilitates the electrical connection of the anode electrode, making maintenance easier, and ensuring the electrode's precise and stable position.

[0057] like Figures 2 to 6 The diagram illustrates a synergistic electrochemical device for hypochlorous acid and hydrogen peroxide. The baffle assembly 7 is located within the first housing 8, and the limiting groove 73 is located within the inner cavity of the first housing 8. The first housing 8 is provided with a fixing groove 81 that limits the anode reaction plate 611. Furthermore, as a preferred embodiment of this invention and not a limitation thereof, designing the baffle assembly, the limiting groove, and the fixing groove all within the inner cavity of the first housing allows for a more compact structure of the entire electrolyte chamber, reducing the space occupied.

[0058] The use of limiting grooves and fixing slots ensures the stability of the anode reaction plate during the reaction process, preventing a decrease in electrolysis efficiency or damage due to positional displacement. It also helps maintain sealing, preventing electrolyte leakage and protecting the electrodes from external environmental influences. Since all critical components are located within the first housing, equipment maintenance or electrode replacement can be easily performed by simply opening the first housing, without disassembling the entire device.

[0059] like Figures 2 to 5 The diagram shows a hypochlorous acid and hydrogen peroxide synergistic electrochemical device, wherein the inlet 2 and outlet 3 are located on the same side of the first housing 8, and the coverage area of ​​the cathode reaction plate 511 is larger than that of the anode reaction plate 611.

[0060] In some embodiments, the cathode reaction plate can first react directly with the electrolyte at the inlet.

[0061] The fact that the inlet and outlet are located on the same side of the first housing simplifies the connection of external pipelines, allows the feed and discharge pipelines to be arranged in a centralized manner, facilitates installation and maintenance, reduces the use of pipe bends and transition connectors, reduces fluid resistance and leakage points, and also helps to make compact use of space and reduce the floor area.

[0062] The cathode reaction plate has a larger coverage area than the anode reaction plate to optimize the efficiency of the electrochemical reaction. During electrolysis, the cathode reaction is more active than the anode reaction or requires more surface area to support it. Increasing the cathode surface area can improve the hydrogen peroxide generation rate because more oxygen molecules can be reduced on the cathode surface. Therefore, increasing the coverage area of ​​the cathode reaction plate ensures that the cathode reaction proceeds more fully and efficiently. Increasing the coverage area of ​​the cathode reaction plate provides sufficient space for product formation. A larger cathode reaction plate also helps to distribute the fluid entering the electrolysis chamber more evenly, which reduces local concentration differences and temperature gradients, thereby improving the uniformity and stability of the electrochemical reaction.

[0063] like Figures 1 to 6 As shown, the implementation method of this embodiment is as follows:

[0064] The synergistic electrochemical device for hypochlorous acid and hydrogen peroxide includes a housing 1, an inlet 2 and an outlet 3 respectively connected to the housing 1, an electrolyte chamber 4 connected to the inlet 2 and the outlet 3 respectively, a cathode reaction assembly 5 and an anode reaction assembly 6 located in the electrolyte chamber 4, and a baffle assembly 7 for increasing the liquid movement. The cathode reaction assembly 5 is used to generate hydrogen peroxide, and the anode reaction assembly 6 is used to generate hypochlorous acid.

[0065] This invention allows for the direct generation of hydrogen peroxide and hypochlorous acid within the electrolyte chamber 4 via the cathode reaction assembly 5 and the anode reaction assembly 6, respectively, eliminating the need for separate preparation and subsequent mixing. This simplifies the process, reduces costs, and enhances the synergistic effect of hypochlorous acid and hydrogen peroxide. The baffle assembly 7 increases the liquid movement distance, effectively improving the mixing effect and enhancing the efficiency and uniformity of the electrochemical reaction. This invention simplifies the process flow, reduces costs, and improves operational convenience, meeting the user's needs for solutions containing both hypochlorous acid and hydrogen peroxide simultaneously.

[0068] The second turbulence section 72 forms a passageway space 74 with the inner wall of the electrolyte chamber 4.

A flow channel 75 for liquid movement is provided between the alternately arranged first turbulence section 71 and the second turbulence section 72. The plurality of passageway spaces 74 and the plurality of flow channels 75 form a reaction channel 76.

[0069] The first turbulence section 71 has a wider extension width than the second turbulence section 72, and the reaction channel 76 is arranged in a "bow" shape.

[0070] The cathode electrode 51 and the anode electrode 61 are located on opposite sides of the reaction channel 76.

The liquid inlet 2 is located on one side of the reaction channel 76, and the liquid outlet 3 is located on the other side of the reaction channel 76.

[0071] The housing 1 includes a first housing 8 and a second housing 9. The liquid inlet 2 and the liquid outlet 3 are both located on the first housing 8. The first housing 8 is provided with a first housing mounting part 80, and the second housing 9 is provided with a second housing mating part 90. The first housing mounting part 80 and the second housing mating part 90 are connected to each other so that the first housing 8 and the second housing 9 enclose the electrolyte chamber 4.

[0072] The first housing mounting part 80 is a snap-fit ​​part, and the second housing mating part 90 is a connecting step part. The connection between the first housing 8 and the second housing 9 is achieved through snap-fit ​​connection.

[0073] The first housing 8 is provided with a first positioning groove 82. The anode electrode 61 is provided with an anode reaction plate 611 connected to the limiting groove 73 and an anode conductive end 612 connected to the anode reaction plate 611 and extending to the outside of the first positioning groove 82.

The cathode electrode 51 is provided with a cathode reaction plate 511 connected to the inner cavity of the second housing 9 and a cathode conductive end 512 connected to the cathode reaction plate 511 and extending to the outside of the second positioning groove 91.
