[0052] Embodiment 1

[0053] The following will be combined Figure 1-Figure 14 , the structure of the electrolytic component 10 of this embodiment is further described.

[0054] See also Figure 1-Figure 6 , this embodiment discloses an electrolytic assembly 10, comprising a first back plate 101, a second back plate 102 and an electrolytic body 103;

[0055] The first back plate 101 is connected with a water inlet connector 1011, a hydrogen connector 1012 and an oxygen connector 1013. The water inlet connector 1011 is used for water supply, the hydrogen connector 1012 is used for outputting hydrogen generated by electrolysis of water, and the oxygen connector 1013 is used for outputting oxygen generated by electrolysis of water.

[0056] The electrolytic body 103 is clamped between the first back plate 101 and the second back plate 102;

[0057] The electrolysis body 103 includes a negative electrode sheet 1031 and a positive electrode sheet 1032. The negative electrode sheet 1031 is provided with a first negative electrode through hole 10311, which is connected to the hydrogen connector 1012 and is used to discharge the hydrogen generated by the electrolysis of water. The positive electrode sheet 1032 is provided with a first positive electrode through hole 10321, which is connected to the oxygen connector 1013 and is used to discharge the oxygen generated by the electrolysis of water.

[0058] A first sealing component 1034 and a proton exchange membrane 1033 are further provided between the negative electrode sheet 1031 and the positive electrode sheet 1032. The first sealing component 1034 includes a first sealing ring 10341 and a second sealing ring 10342. The outer edge of the proton exchange membrane 1033 is clamped between the first sealing ring 10341 and the second sealing ring 10342. The inner wall of the first sealing ring 10341 and the inner wall of the second sealing ring 10342 together enclose a first electrolysis space. The first electrolysis space is connected to the water inlet connector 1011.

[0059] The second sealing component 104 is connected between the negative electrode sheet 1031 and the first back plate 101 , and the second sealing component 104 is also connected between the positive electrode sheet 1032 and the second back plate 102 .

[0060] The above structure can effectively fix the proton exchange membrane 1033 by clamping the outer peripheral edge of the proton exchange membrane 1033 through the first sealing ring 10341 and the second sealing ring 10342, and can also effectively ensure the edge sealing effect; in addition, through the arrangement of the second sealing components 104 on both sides, the sealing between the outer edge of the negative electrode sheet 1031 and the first back plate 101, and the sealing between the outer edge of the positive electrode sheet 1032 and the second back plate 102 are effectively increased, thereby enhancing the sealing of the overall electrolytic component 10 and avoiding water leakage that affects the electrolysis efficiency.

[0061] In some embodiments, the second sealing assembly 104 includes a support washer 1041 and a third sealing ring 1042 . The third sealing ring 1042 is disposed on both sides of the support washer 1041 . The hardness of the support washer 1041 is greater than that of the third sealing ring 1042 .

[0062] The material of the sealing ring is usually soft and is prone to deformation and becoming uneven after assembly and pressing. The above phenomenon is more likely to occur in sealing rings with a thicker thickness. By providing a support gasket 1041 with greater hardness between the two third sealing rings 1042, the third sealing rings 1042 on both sides can be supported, so that the third sealing rings 1042 can fit tightly on the harder support gasket 1041 to ensure its flatness. In addition, it also avoids the problem of gaps caused by loose contact due to extrusion deformation when the two layers of third sealing rings 1042 are in direct contact, thereby affecting the sealing.

[0063] Furthermore, the contact surfaces of the support gasket 1041 and the third sealing ring 1042 are both planes.

[0064] In addition, through the provision of the second sealing component 104, a certain space is formed between the positive electrode sheet 1032 and the second back plate 102, and a certain space is also formed between the negative electrode sheet 1031 and the first back plate 101. These spaces can serve as temporary water storage, increase the water storage space and water capacity, and allow the positive and negative electrode sheets 1031 to be fully soaked to ensure electrolysis efficiency.

[0065] In some embodiments, the support gasket 1041 is a polytetrafluoro gasket, and the third sealing ring 1042 is a silicone gasket.

[0066] PTFE gaskets, also known as polytetrafluoroethylene gaskets, have good properties such as corrosion resistance, aging resistance and non-conductivity. They are harder than silicone and have good supporting properties.

[0067] It is understandable that the support washer 1041 may also be other washers with a certain hardness.

[0068] Preferably, the first sealing ring 10341, the second sealing ring 10342 and the third sealing ring 1043 can be made of the same material, all of which are silicone gaskets, and their lengths, widths and thicknesses can also be of the same specifications.

[0069] It is also possible that the material of the first sealing ring 10341 and the second sealing ring 10342 is the same, but the material of the third sealing ring 1042 is different.

[0070] It can be understood that the first sealing ring 10341, the second sealing ring 10342, the third sealing ring 1042 and the supporting gasket 1041 are all annular structures, and the shapes can be square, circular, elliptical or other shapes, which are not limited here.

[0071] In some embodiments, Figure 6 As shown, the outer edge of the support gasket 1041 protrudes from the outer edge of the third sealing ring 1042, so that when the third sealing ring 1042 is squeezed and deformed and extends to the surroundings and becomes larger, it can also provide effective support;

[0072] The outer edges of the positive electrode sheet 1032 and the negative electrode sheet 1031 are both protruding from the outer edge of the third sealing ring 1042, so as to play a certain supporting role when the third sealing ring 1042 directly attached thereto is squeezed and deformed and extends to the surroundings and becomes larger;

[0073] Furthermore, the outer edges of the positive electrode sheet 1032 and the negative electrode sheet 1031 both protrude beyond the outer edge of the first sealing component 1034 , so as to provide a certain support when the first sealing component 1034 is squeezed and deformed and extends in all directions.

[0074] In some embodiments, Figure 6 As shown, the protruding distance L1 of the outer edge of the support gasket 1041 from the outer edge of the third sealing ring 1042 is 0.5 to 2 mm. If the protruding distance is too small, it is difficult to provide effective support when the third sealing ring 1042 is deformed. If the distance is too large, it will cause waste of materials and increase weight.

[0075] The outer edge of the positive electrode sheet 1032 protrudes from the outer edge of the first sealing component 1034 by a protruding distance L2 of 0.5 to 2 mm, and the outer edge of the negative electrode sheet 1031 protrudes from the outer edge of the first sealing component 1034 by a protruding distance L3 of 0.5 to 2 mm.

[0076] In some embodiments, the thickness of the first sealing ring 10341 and the second sealing ring 10342 are both 0.1 to 1.5 mm.

[0077] The thickness of the third sealing ring 1042 may be 0.1-1.5 mm.

[0078] The thickness of the support washer 1041 may be 0.1-1.5 mm.

[0079] In some embodiments, Figure 9-10 As shown, a first cavity 1035 is formed between the negative electrode sheet 1031 and the proton exchange membrane 1033, a first titanium mesh (not shown in the figure) is arranged in the first cavity 1035, and the first titanium mesh is located inside the first sealing ring 10341; a second cavity 1036 is formed between the positive electrode sheet 1032 and the proton exchange membrane 1033, a second titanium mesh (not shown in the figure) is arranged in the second cavity 1036, and the second titanium mesh is located inside the second sealing ring 10342.

[0080] The first titanium mesh and the second titanium mesh are both mesh structures made of titanium material. Through the above arrangement, the electrolysis efficiency can be effectively enhanced, and the fixing reliability of the proton exchange membrane 1033 can be better guaranteed.

[0081] In some embodiments, the negative electrode sheet 1031 is provided with a second negative electrode through hole 10312, which is connected to the water inlet connector 1011, and the positive electrode sheet 1032 is provided with a second positive electrode through hole 10322, which is also connected to the water inlet through hole, so that water entering from the water inlet connector 1011 can enter between the positive and negative electrode sheets 1031 through the second negative electrode through hole 10312, and penetrate or flow through to the second positive electrode through hole 10322 to ensure sufficient electrolysis.

[0082] In a specific implementation, in order to facilitate the water in the water inlet joint 1011 to enter the electrolysis body 103 to achieve electrolysis and gas escape, as shown in FIG. Fig.13 As shown, a first hole 10421 and a second hole 10423 can be provided on the third sealing ring 1042 directly in contact with the negative electrode sheet 1031, a first communication path 10422 is opened between the first hole 10421 and the inner wall of the third sealing ring 1042 to achieve communication, a second communication path 10424 is opened between the second hole 10423 and the inner wall of the third sealing ring 1042 to achieve communication, the first hole 10421 is connected to the water inlet joint 1011, and the second hole 10423 is connected to the hydrogen joint 1012, then, The water in the water inlet connector 1011 can enter the third sealing ring 1042 through the first hole 10421 and the first communication path 10422, that is, enter the first cavity 1035, and then enter between the positive and negative electrode sheets 1031 through the second negative electrode through hole 10312 on the negative electrode sheet 1031, and penetrate or flow through the second positive electrode through hole 10322 to enter the second cavity 1036 to ensure that the electrolysis of water is fully carried out. The hydrogen generated by the electrolysis finally enters the second hole 10423 through the second communication path 10424 and is output through the hydrogen connector 1012.

[0083] Similar, such as Fig.14 As shown, a third channel 10425 can also be set on the third sealing ring 1042 that is directly in contact with the positive electrode plate 1032, and a third connecting path 10426 is opened between the third channel 10425 and the inner wall of the third sealing ring 1042 to achieve communication. The third channel 10425 is connected to the oxygen connector 1013, and the oxygen generated by electrolysis eventually enters the third channel 10425 through the third connecting path 10426 and is output through the oxygen connector 1013; to avoid mixing of hydrogen and oxygen, the second channel 10423 and the third channel 10425 can be respectively set on both sides of the sealing ring.

[0084] It is understandable that the communication of water or gas can also be achieved through other forms of communication.

[0085] In some embodiments, Figure 7-Figure 8As shown, the first back plate 101 and the second back plate 102 are connected by the first bolt 105, and the first bolt 105 sequentially penetrates the first back plate 101, the second sealing component 104 between the first back plate 101 and the negative electrode plate 1031, the negative electrode plate 1031, the first sealing component 1034, the positive electrode plate 1032, the second sealing component 104 between the positive electrode plate 1032 and the second back plate 102, and the second back plate 102, that is, except for the proton exchange membrane 1033 which is not penetrated by the first bolt 105, the edges of other components are penetrated by the first bolt 105, and nuts need to be locked after penetration.

[0086] The connection is made through the first bolt 105, which is simple to operate and has high connection reliability, and the clamping force can also be easily adjusted.

[0087] To increase stability, a plurality of first bolts 105 are disposed around the first back plate 101 .

[0088] In some embodiments, Figure 8 As shown, the outer edge of the proton exchange membrane 1033 is clamped between the first sealing ring 10341 and the second sealing ring 10342 by a clamping length L4 of 0.5 to 2 mm, preferably 0.5 mm. The clamping length should not be too short, otherwise the fixing reliability of the proton exchange membrane will be reduced. In addition, since the price of the proton exchange membrane is relatively expensive, if the clamping length is too long, the overall size of the proton exchange membrane will inevitably increase while keeping its exposed area unchanged, which will lead to increased costs.

[0089] In some embodiments, Figure 1 , Fig.11 and Fig.12 As shown, a first conductive protrusion 10313 is disposed on the edge of the negative electrode sheet 1031 , and a second conductive protrusion 10323 is disposed on the edge of the positive electrode sheet 1032 . Both the first conductive protrusion 10313 and the second conductive protrusion 10323 extend to the outside of the electrolytic component 10 .

[0090] The electrolytic body 103 needs to be connected to the circuit assembly, which includes a battery and a circuit board. The battery supplies power to the circuit board. The positive electrode sheet 1032 and the negative electrode sheet 1031 can be connected to the positive and negative electrodes corresponding to the circuit in the circuit board through conductive members such as wires. The first conductive protrusion 10313 and the second conductive protrusion 10323 are provided to facilitate the connection between the positive and negative electrode sheets 1031 and the circuit board.

[0091] Furthermore, a first mounting hole 10314 for the conductive member to pass through is provided on the first conductive protrusion 10313 , and similarly, a second mounting hole 10324 for the conductive member to pass through may also be provided on the second conductive protrusion 10323 .

[0092] In some embodiments, the first conductive protrusion 10313 and the second conductive protrusion 10323 are disposed on the same side to facilitate external circuit components and improve space utilization.

[0093] In the above-mentioned electrolytic assembly 10, the negative electrode sheet 1031 and the positive electrode sheet 1032 are both conductive elements and can be made of conductive metal.

[0094] As a highly efficient semipermeable membrane, the proton exchange membrane 1033 has selective permeability, which can accurately allow hydrogen ions to pass through while blocking hydroxide ions. Through the proton exchange membrane 1033, hydrogen ions and electrons can be smoothly combined to generate purer hydrogen.

[0095] The traditional PEM hydrogen production method requires coating the surface of the proton exchange membrane 1033 (Proton Exchange Membrane, PEM) with a heavy metal coating as a catalyst. For example, the proton exchange membrane 1033 is coated with a catalyst - iridium oxide near the anode side; and the other side is coated with a catalyst - platinum carbon. When electrolyzing water to produce hydrogen in this way, heavy metal materials are easy to fall off and enter the user's body with the drinking action. Such heavy metals are toxic and will have adverse effects on the human body. In order to avoid such effects, the proton exchange membrane 1033 in the electrolysis body 103 of the present embodiment is not provided with a catalyst coating, and the negative electrode sheet 1031 and the positive electrode sheet 1032 are both titanium electrode sheets made of titanium material. Electrolysis of hydrogen is achieved through the electrolysis body 103, and the produced hydrogen can be drunk with water without the occurrence of heavy metal poisoning, making electrolysis of water safer and ensuring human health.

[0096] In addition, since titanium electrodes have good electrical conductivity and strong stability, when electrolysis is performed by impacting the titanium electrodes with direct current voltage, the efficient and stable electrolysis operation can also be effectively guaranteed.

[0097] The electrolysis principle of the above-mentioned electrolysis component 10 is as follows: after power is turned on, water enters the second negative electrode through hole 10312 of the negative electrode sheet 1031 through the water inlet joint 1011 and flows into the first electrolysis space and flows through the proton exchange membrane 1033, so that the proton exchange membrane 1033 is infiltrated, and when it further flows to the positive electrode sheet 1032, the water in the electrolysis component 10 is electrolyzed to produce hydrogen and oxygen, that is, the electrons of the negative electrode enter the water and react with hydrogen ions to produce hydrogen, and the positive electrode accepts electrons from hydroxyl groups and becomes oxygen, wherein the generated hydrogen escapes through the first negative electrode through hole 10311 and finally enters the hydrogen joint 1012 for discharge, and the oxygen escapes through the first positive electrode through hole 10321 and finally enters the oxygen joint 1013 for discharge.

[0098] The first back plate 101 and the second back plate 102 in the above embodiment may be in a square, circular or other shapes.

[0099] The electrolytic assembly of the above embodiment has good sealing performance and can effectively ensure the electrolysis efficiency; the overall structure is compact and easy to assemble and maintain.
