DETAILED DESCRIPTION

[0034] The advantages and features of the present application will be more clearly understood from the following detailed description of preferred embodiments of the present application, taken in conjunction with the accompanying drawings, in which:

[0035] As Figures 1-11 shown is an electrolytic cell for preparing hydrogen-rich water according to the present embodiment, which forms hydrogen gas by electrolyzing water, and mixes the hydrogen gas and water to form hydrogen-rich water. The electrolytic cell comprises a hydrogen water mixing plate 1, a negative plate 2, a membrane electrode 3, a positive plate 4, and an oxygen water mixing plate 5, which are sequentially and sealingly assembled. A first end plate 6 is arranged on the outer side of the hydrogen water mixing plate 1, and a second end plate 61 is arranged on the outer side of the oxygen water mixing plate 5. A bolt assembly 81 is connected between the first end plate 6 and the second end plate 61. The hydrogen water mixing plate 1, the negative plate 2, the membrane electrode 3, the positive plate 4, and the oxygen water mixing plate 5 are fixed between the first end plate 6 and the second end plate 61 by locking the bolt assembly 81. In the specific structural design, the hydrogen water mixing plate 1, the oxygen water mixing plate 5, the negative plate 2, and the positive plate 4 are provided with through holes. The bolt assembly 81 is inserted into the hydrogen water mixing plate 1, the oxygen water mixing plate 5, the negative plate 2, and the positive plate 4 through the through holes, so as to position the above-mentioned components.

[0036] The hydrogen water mixing plate 1 and the negative plate 2 are processed with a meandering mixing channel 13. The mixing channel 13 includes a meandering main channel 131 and several branch channels 132 arranged along the extension direction of the main channel 131. By setting the main channel 131 as a meandering structure, the length of the main channel 131 is increased in a limited space. The main channel 131 has a first end and a second end in the length direction. The branch channel 132 extends along a preset direction and has a first end connected with the main channel 131 and a second end away from the first end and closed. The hydrogen water mixing plate 1 is processed with a first water inlet 11 and a hydrogen water outlet 12. The hydrogen water outlet 12 is connected with the first end of the main channel 131. The negative plate 2 is processed with a first through hole 21 connected with the first water inlet 11 and a second through hole 22 connected with the second end of the main channel 131. Through the above structure design, the water outside can be transported to the side of the negative plate 2 away from the hydrogen water mixing plate 1 through the first water inlet 11 and the first through hole 21 by the water pump to perform electrolysis. The hydrogen and water after electrolysis can enter the main channel 131 through the second through hole 22 and be transported from the second end to the first end of the main channel 131, and then be discharged through the hydrogen water outlet 12. In the transportation process, the hydrogen and water flow dispersedly in the main channel 131 and the branch channel 132, form vortexes and collide with each other, and go through the processes of vortex and collision for several times, so that the hydrogen is quickly and fully dissolved in the water to obtain hydrogen-rich water with high concentration.

[0037] In the specific structural design, the mixing flow channel 13 is a groove structure formed on the end surface of the hydrogen-water mixing plate 1 facing the negative plate 2. A first annular sealing member 9 is arranged around the periphery of the mixing flow channel 13 between the negative plate 2 and the hydrogen-water mixing plate 1. The first annular sealing member 9 is sealed against the negative plate 2 and the hydrogen-water mixing plate 1 to seal the mixing flow channel 13 in the internal space of the first annular sealing member 9. An annular positioning groove is machined on the end surface of the hydrogen-water mixing plate 1 around the periphery of the mixing flow channel 13. The first annular sealing member 9 is embedded in the annular positioning groove. In addition, the first water inlet 11 and the hydrogen-water outlet 12 are located on the same side of the side surface of the hydrogen-water mixing plate 1. A first butt joint hole 14 is machined on the end surface of the hydrogen-water mixing plate 1, and the first water inlet 11 and the first butt joint hole 14 are connected by a channel structure. The first butt joint hole 14 is located outside the first annular sealing member 9. A second butt joint hole 15 is machined on the end surface of the hydrogen-water mixing plate 1 at the first end (the first end of the main flow channel 131) of the mixing flow channel 13. The hydrogen-water outlet 12 and the second butt joint hole 15 are connected by a channel structure. When the hydrogen-water mixing plate 1 and the negative plate 2 are stacked, the first through hole 21 and the first butt joint hole 14 are connected in a butt joint manner, and the second through hole 22 and the second end (the second end of the main flow channel 131) of the mixing flow channel 13 are connected in a butt joint manner. Among them, a fourth annular sealing member 94 is arranged around the periphery of the first butt joint hole 14 between the negative plate 2 and the hydrogen-water mixing plate 1 to improve the sealing effect of the overall structure. The fourth annular sealing member 94 and the first annular sealing member 9 are integrally formed.

[0038] In the specific structural design, the second end of the branch flow channel 132 is formed with an arc-shaped side wall 133. The arc-shaped side wall 133 is smoothly connected with the two side walls in the width direction of the branch flow channel 132. The arc-shaped side wall 133 plays a role in guiding the flow of fluid to improve the vortex effect.

[0039] Among them, the main flow channel 131 has a fluid advancing direction (the fluid flows from the second end of the main flow channel 131 to the first end of the main flow channel 131). The first end of the branch flow channel 132 is located on the upstream side of the fluid advancing direction, and the second end is located on the downstream side of the fluid advancing direction. Through the above structural design, the branch flow channel 132 can enhance the resistance of the fluid conveying in the mixing flow channel 13, so that the hydrogen and water are more violently stirred in the mixing flow channel 13, thereby increasing the mixing effect of the hydrogen and water in the mixing flow channel 13.

The water outside is delivered through the linear flow channel 53, forms a divergent water flow through the third through hole 41, and then flows out through the fourth through hole 42. In this way, the water can more fully wet the second plate net 33 for electrolysis, so as to reduce the local electrolysis operation temperature inside the electrolytic cell and improve the service life of the electrolytic cell.

[0042] The linear flow channel 53 is a groove structure formed on the end face of the oxygen water mixing plate 5 facing the positive plate 4. The second annular sealing member 91 is arranged around the periphery of the linear flow channel 53 between the positive plate 4 and the oxygen water mixing plate 5. The second annular sealing member 91 is sealed and abuts between the positive plate 4 and the oxygen water mixing plate 5, so that the linear flow channel 53 is sealed in the internal space of the second annular sealing member 91, so as to improve the sealing performance of the overall structure. The end face of the oxygen water mixing plate 5 is processed with an annular positioning groove around the periphery of the linear flow channel 53. The second annular sealing member 91 is embedded in the annular positioning groove.

[0043] The third butt joint hole 54 is processed on the end face of the oxygen water mixing plate 5, and the second water inlet 51 and the third butt joint hole 54 are communicated through a channel structure. The third butt joint hole 54 is located at the first end of the linear flow channel 53. The fourth butt joint hole 55 is processed on the end face of the oxygen water mixing plate 5, and the fourth butt joint hole 55 is located outside the second annular sealing member 91. The oxygen water outlet 52 and the fourth butt joint hole 55 are communicated through a channel structure. When the oxygen water mixing plate 5 and the positive plate 4 are stacked, the third through hole 41 is communicated with the second end of the linear flow channel 53, and the fourth through hole 42 is communicated with the fourth butt joint hole 55. The third annular sealing member 93 is arranged around the periphery of the fourth butt joint hole 55 between the positive plate 4 and the oxygen water mixing plate 5, so as to improve the sealing effect of the overall structure.

The aforementioned bolt assembly 81 is inserted into the outer frame 8. The membrane electrode 3 includes an inner frame 34, an exchange film 31, a first mesh 32, and a second mesh 33. The inner frame 34 is installed inside the outer frame 8 and is fixed in position by the outer frame 8. The exchange film 31 is arranged inside the inner frame 34 and can be an ion exchange film 31 or an ion exchange film 31. The first mesh 32 is arranged between the exchange film 31 and the negative plate 2, and the second mesh 33 is arranged between the exchange film 31 and the positive plate 4.
