Description

Technical Field

[0001] This utility model relates to the field of hydrogen cup technology, and in particular to a hydrogen cup electrolysis cell assembly. Background Technology

[0002] Hydrogen cups can electrolyze drinking water to produce hydrogen gas, thereby increasing the hydrogen concentration in the drinking water and forming hydrogen-rich water. Drinking hydrogen-rich water is beneficial to human health. Existing hydrogen cups consist of a cup body and an electrolysis tank located at the bottom of the cup body. When existing electrolysis tanks electrolyze drinking water, the oxygen produced is discharged through the same pipe as the water. On the one hand, the pipe is prone to blockage, affecting drainage and oxygen discharge. On the other hand, when oxygen and water are discharged together, water can easily spray out from the pipe opening, wetting surrounding objects. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings of existing electrolytic cells, this utility model proposes an electrolytic cell assembly with a pipeline structure that is not easily blocked and the first pipe opening is not easily sprayed with water.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A hydrogen cup electrolyzer assembly includes an upper cover, a cathode plate, a diaphragm, a bipolar plate, an anode plate, and a lower cover, which are sequentially pressed together from top to bottom. A cavity is formed between the anode plate and the lower cover. The electrolyzer assembly also includes a pipeline structure, which includes a main pipeline and branch pipelines. The upper end of the main pipeline is connected to the lower side of the cavity, and the lower end of the main pipeline extends to the bottom of the hydrogen cup to form a first port. An outlet is provided on one side of the upper end of the main pipeline, and the inner end of the outlet is inclined downward. One end of the branch pipeline is connected to the outer end of the outlet, and the other end of the branch pipeline extends to the side of the hydrogen cup to form a second port.

[0005] With the above setup, the pipeline structure has two ports. If one port is blocked, the other port can still drain water and oxygen, without affecting the drainage and oxygenation of the pipeline structure. The pipeline structure is not easily blocked. In addition, the branch pipes can assist in oxygenation and reduce the pressure in the main pipeline. The first port is less likely to spray water.

[0006] Furthermore, a slope is provided on the upper side of the lower cover to guide the water flow to the main pipeline.

[0007] The above design prevents water from accumulating on the upper side of the lower cover.

[0008] Furthermore, the diameter of the main pipeline is larger than that of the branch pipelines.

[0009] The above settings accelerate the drainage speed of the main pipeline and further prevent water from spraying out of the first pipe opening.

[0010] Furthermore, the second opening is higher than the first opening.

[0011] The above settings further prevent blockage of the pipeline structure.

[0012] Furthermore, the main pipeline is located near the edge of the lower cover, and the air outlet is located on the side of the main pipeline away from the center of the lower cover.

[0013] The above setup helps to reduce the length of branch pipes and improve oxygen removal efficiency.

[0014] Furthermore, the electrolytic cell assembly also includes a first sealing ring, a second sealing ring, and a third sealing ring. A first annular groove is provided circumferentially on the lower side of the upper cover. The first sealing ring is disposed between the upper cover and the cathode plate and is embedded in the first annular groove. The second sealing ring is disposed between the cathode plate, the diaphragm, and the anode plate. A second annular groove is provided circumferentially on the upper side of the lower cover. The third sealing ring is disposed between the anode plate and the lower cover and is embedded in the second annular groove.

[0015] The above settings improve sealing and prevent water leakage from the electrolytic cell components.

[0016] Furthermore, the electrolytic cell assembly also includes an annular partition, an anode tab, and a cathode tab. The anode tab and cathode tab are respectively fixedly connected to one side of the anode plate and the cathode plate. The annular partition is locked between the upper cover and the lower cover. The inner circumference of the annular partition supports the outer circumference of the cathode plate and the anode plate. The upper and lower sides of the annular partition are respectively provided with a first groove and a second groove. The cathode tab extends out of the annular partition through the first groove and the cathode tab extends out of the annular partition through the second groove.

[0017] The above settings improve the structural stability of the electrolytic cell assembly.

[0018] Furthermore, a first positioning hole is provided on the cathode tab, and a first positioning post is fixedly connected to the first groove, with the first positioning post penetrating through the first positioning hole; a second positioning hole is provided on the anode tab, and a second positioning post is fixedly connected to the second groove, with the second positioning post penetrating through the second positioning hole.

[0019] The above settings further enhance the stability of the anode plate and the anode plate.

[0020] Furthermore, a first positioning rib is fixedly connected to the upper side of the annular partition, and the two ends of the first positioning rib extend along the circumference of the annular partition to the opposite sides of the first groove. A first positioning groove adapted to the first positioning rib is provided on the lower side of the upper cover, and the first positioning rib is set in the first positioning groove. A second positioning rib is fixedly connected to the lower side of the annular partition, and the two ends of the second positioning rib extend along the circumference of the annular partition to the opposite sides of the second groove. A second positioning groove adapted to the second positioning rib is provided on the upper side of the lower cover, and the second positioning rib is embedded in the second positioning groove.

[0021] The above design improves the stability of the upper and lower covers on the upper and lower sides of the annular partition; in addition, it also prevents water leakage between the upper and lower covers. Attached Figure Description

[0026] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0027] like Figures 1 to 4 A hydrogen cup electrolyzer assembly includes an upper cover 2, a cathode plate 3, a diaphragm 4, a bipolar plate 5, an anode plate 6, and a lower cover 7, which are sequentially pressed together from top to bottom. A cavity is formed between the anode plate 6 and the lower cover 7. The electrolyzer assembly also includes a pipeline structure, which includes a main pipeline 8 and a branch pipeline 9. The upper end of the main pipeline 8 is connected to the lower side of the cavity, and the lower end of the main pipeline 8 extends to the bottom of the hydrogen cup to form a first port (not shown in the figure). An air outlet 10 is provided on one side of the upper end of the main pipeline 8. The inner end of the air outlet 10 is inclined downward. One end of the branch pipeline 9 is connected to the outer end of the air outlet 10, and the other end of the branch pipeline 9 extends to the side of the hydrogen cup to form a second port (not shown in the figure).

[0028] With the above setup, the pipeline structure has two ports. If one port is blocked, the other port can still drain water and oxygen, without affecting the drainage and oxygenation of the pipeline structure. The pipeline structure is not easily blocked. In addition, the branch pipe 9 can assist in oxygenation and reduce the pressure in the main pipe 8, making it less likely for water to spray out from the first port.

[0029] The hydrogen cup of this application includes a cup body and an electrolytic cell assembly. The cup body is basically cylindrical, and the electrolytic cell assembly is located at the bottom of the cup body. The upper cover 2 is an annular structure that fits the cup body, and the lower cover 7 is basically a solid circular structure. The upper cover 2 and the lower cover 7 lock the cathode plate 3, diaphragm 4, bipolar plate 5, and cathode plate 3 together. After drinking water is filled into the cup body, the drinking water is isolated on the upper side of the bipolar plate 5. A battery is installed on the lower side of the electrolytic cell assembly. The two ends of the battery are connected to the anode plate 6 and the cathode plate 3, respectively. Hydrogen gas is generated at the cathode plate 3 to increase the hydrogen concentration in the drinking water. At the anode plate 6, oxygen and water are generated. For the specific principle of the electrolytic cell assembly, please refer to the principle of the PEM electrolytic cell, which will not be repeated here. The water and oxygen generated by the anode plate 6 are initially located in the cavity. The water drips from the anode plate 6 to the lower cover 7, and then is discharged to the outside of the cup through the main pipe 8 and the first pipe. The oxygen is discharged to the outside of the cup through the air outlet 10, the branch pipe 9 and the second pipe. The inner end of the air outlet 10 is inclined downward to prevent water from flowing into the branch pipe 9. The oxygen is discharged through the branch pipe 9, which reduces the pressure in the main pipe 8, thereby preventing water from spraying out from the first pipe.

[0030] As one implementation method, the upper side of the lower cover 7 is provided with a slope to guide the water flow to the main pipeline 8.

[0031] The above settings prevent water from accumulating on the upper side of the lower cover 7.

[0032] The lower cover 7 of this application has a slope on its upper side. After the water droplets generated on the anode plate 6 fall onto the lower cover 7, the slope will guide the water to the main pipeline 8 and discharge the water to the outside in time to prevent water accumulation on the upper side of the lower cover 7.

[0033] As one implementation method, the diameter of the main pipe 8 is larger than the diameter of the branch pipe 9.

[0034] The above settings accelerate the drainage speed of main pipeline 8 and further prevent water from spraying out of the first pipe opening.

[0035] The inner diameter of the main pipe 8 in this application is between 2.5-3.5 mm, and the inner diameter of the branch pipe 9 is between 1-2 mm. When the diameter of the main pipe 8 is larger than that of the branch pipe 9, the main pipe 8 can discharge water to the outside of the cup in time. The diameter of the branch pipe 9 is smaller, specifically 1.5 mm, which ensures the oxygen discharge speed while preventing foreign objects from entering.

[0036] As one implementation method, the second pipe opening is higher than the first pipe opening.

[0037] The above settings further prevent blockage of the pipeline structure.

[0038] The first and second pipe openings of this application are not at the same height. In actual use, the first and second pipe openings will not be blocked synchronously, thereby preventing blockage of the pipeline structure.

[0039] As one implementation, the main pipe 8 is located near the edge of the lower cover 7, and the air outlet 10 is located on the side of the main pipe 8 away from the center of the lower cover 7.

[0040] The above settings help to reduce the length of branch pipe 9 and improve oxygen removal efficiency.

[0041] The electrolytic cell assembly of this application is coaxially mounted at the lower end of the cup body, and the gas outlet 10 is located on the side of the main pipeline 8 away from the center of the lower cover 7. The branch pipeline 9 extends to the outside of the cup body with a shorter path and faster oxygen removal speed.

[0042] As one implementation, the electrolytic cell assembly also includes a first sealing ring 11, a second sealing ring 12, and a third sealing ring 13. A first annular groove is provided on the lower side of the upper cover 2 along the circumferential direction. The first sealing ring 11 is disposed between the upper cover 2 and the cathode plate 3 and is embedded in the first annular groove. The second sealing ring 12 is disposed between the cathode plate 3, the diaphragm 4, and the anode plate 6. A second annular groove is provided on the upper side of the lower cover 7 along the circumferential direction. The third sealing ring 13 is disposed between the anode plate 6 and the lower cover 7 and is embedded in the second annular groove.

[0043] The above settings improve sealing and prevent water leakage from the electrolytic cell components.

[0044] The electrolytic cell assembly of this application serves the dual purpose of electrolytic hydrogen production and cup bottom. The first sealing ring 11 is pressed between the upper cover 2 and the cathode plate 3 to prevent water leakage between the upper cover 2 and the cathode plate 3. The diaphragm 4 is flattened between the cathode plate 3 and the bipolar plate 5 to prevent deformation of the diaphragm 4. The lower side of the bipolar plate 5 is in contact with the anode plate 6. The upper side of the second sealing ring 12 presses against the lower side of the diaphragm 4 and the lower side presses against the upper side of the cathode plate 3. The inner circumference of the second sealing ring 12 is in contact with the outer circumference of the bipolar plate 5 to prevent water leakage between the cathode plate 3 and the anode plate 6. The third sealing ring 13 is pressed between the lower cover 7 and the anode plate 6 to prevent water leakage between the lower cover 7 and the anode plate 6.

[0045] As one implementation, the electrolytic cell assembly also includes an annular partition 14, an anode tab 15, and a cathode tab 16. The anode tab 15 and the cathode tab 16 are respectively fixedly connected to one side of the anode plate 6 and the cathode plate 3. The annular partition 14 is locked between the upper cover 2 and the lower cover 7. The inner circumference of the annular partition 14 supports the outer circumference of the cathode plate 3 and the anode plate 6. The upper and lower sides of the annular partition 14 are respectively provided with a first groove 17 and a second groove 18. The cathode tab 16 extends out of the annular partition 14 through the first groove 17 and the cathode tab 16 extends out of the annular partition 14 through the second groove 18.

[0046] The above settings improve the structural stability of the electrolytic cell assembly.

[0047] The upper cover 2 and lower cover 7 of this application are flush with the outer periphery of the annular partition 14, which improves the aesthetics. The inner periphery of the annular partition 14 supports the outer periphery of the cathode plate 3 and the anode plate 6, and plays a positioning and supporting role. A first groove 17 is provided on the upper side of the annular partition 14 and a second groove 18 is provided on the lower side, which facilitates the extension of the cathode tab 16 and the anode tab 15 to the outside of the annular partition 14, which facilitates wiring. In this application, the cathode tab 16 and the anode tab 15 extend in opposite directions.

[0048] In one implementation, a first positioning hole 19 is provided on the cathode tab 16, and a first positioning post 20 is fixedly connected to the first groove 17, with the first positioning post 20 penetrating through the first positioning hole 19. A second positioning hole 21 is provided on the anode tab 15, and a second positioning post 22 is fixedly connected to the second groove 18, with the second positioning post 22 penetrating through the second positioning hole 21.

[0049] The above settings further enhance the stability of anode plate 6 and anode plate 6.

[0050] The first positioning post 20 of this application is adapted to the first positioning hole 19. After the first positioning post 20 is inserted into the first positioning hole 19, it prevents the cathode plate 3 from rotating. Similarly, after the second positioning post 22 is inserted into the second positioning hole 21, it prevents the anode plate 6 from rotating.

[0051] As one implementation, a first positioning rib 23 is fixedly connected to the upper side of the annular partition 14. The two ends of the first positioning rib 23 extend circumferentially along the annular partition 14 to the opposite sides of the first groove 17. A first positioning groove 26 adapted to the first positioning rib 23 is provided on the lower side of the upper cover 2, and the first positioning rib 23 is disposed in the first positioning groove. A second positioning rib 24 is fixedly connected to the lower side of the annular partition 14. The two ends of the second positioning rib 24 extend circumferentially along the annular partition 14 to the opposite sides of the second groove 18. A second positioning groove 25 adapted to the second positioning rib 24 is provided on the upper side of the lower cover 7, and the second positioning rib 24 is embedded in the second positioning groove 25.

[0052] The above-mentioned design improves the stability of the upper cover 2 and the lower cover 7 on the upper and lower sides of the annular partition 14; in addition, it also prevents water leakage between the upper cover 2 and the lower cover 7.

[0053] The first positioning rib 23 of this application increases the contact area between the upper cover 2 and the annular partition 14, and the second positioning rib 24 increases the contact area between the lower cover 7 and the annular partition 14, thereby improving the leak-proof effect.

[0054] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
