[0052] Example one

[0053] The following will be combined Figures 1-14 The structure of the electrolysis assembly 10 of the embodiment is further described.

[0054] Referring to Figures 1-6 The embodiment discloses an electrolysis assembly 10, comprising a first back plate 101, a second back plate 102 and an electrolysis body 103;

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

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

[0057] The electrolysis body 103 comprises 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, the first negative electrode through hole 10311 is communicated with the hydrogen joint 1012, and is used for discharging hydrogen generated by electrolysis of water; the positive electrode sheet 1032 is provided with a first positive electrode through hole 10321, the first positive electrode through hole 10321 is communicated with the oxygen joint 1013, and is used for discharging oxygen generated by electrolysis of water;

[0058] The negative electrode sheet 1031 and the positive electrode sheet 1032 are further provided with a first sealing assembly 1034 and a proton exchange membrane 1033, the first sealing assembly 1034 comprises a first sealing ring 10341 and a second sealing ring 10342, and 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 jointly enclose a first electrolysis space, and the first electrolysis space is communicated with the water inlet joint 1011;

[0059] The negative electrode sheet 1031 and the first back plate 101 are connected with a second sealing assembly 104, and the positive electrode sheet 1032 and the second back plate 102 are also connected with the second sealing assembly 104.

[0060] The structure can clamp the outer peripheral edge of the proton exchange membrane 1033 through the first sealing ring 10341 and the second sealing ring 10342, can effectively fix the proton exchange membrane 1033, and can also effectively guarantee the edge sealing effect; in addition, the second sealing assembly 104 arranged on the two sides can effectively increase the sealing performance between the outer edge of the negative electrode sheet 1031 and the first back plate 101 and the sealing performance between the outer edge of the positive electrode sheet 1032 and the second back plate 102, thereby enhancing the sealing performance of the whole electrolysis assembly 10 and avoiding the water leakage phenomenon to affect the electrolysis efficiency.

[0061] In some embodiments, the second sealing assembly 104 comprises a supporting gasket 1041 and a third sealing ring 1042, the two sides of the supporting gasket 1041 are provided with the third sealing ring 1042, and the hardness of the supporting gasket 1041 is greater than the hardness of the third sealing ring 1042.

[0062] The material of the sealing ring is generally soft, and is prone to deformation and unevenness after assembly and pressing. The third sealing ring 1042 with a larger thickness is more prone to the above-mentioned phenomenon. By arranging the support washer 1041 with a larger hardness between the two third sealing rings 1042, the support function of the two third sealing rings 1042 can be achieved, so that the third sealing ring 1042 can be tightly attached to the relatively hard support washer 1041 to ensure the flatness. In addition, the problem of gaps caused by the extrusion deformation of the two layers of third sealing rings 1042 when they are in contact can be avoided, thereby affecting the sealing performance.

[0063] Further, the contact surfaces of the support washer 1041 and the third sealing ring 1042 are both flat.

[0064] In addition, the arrangement of the second sealing assembly 104 also forms a certain space between the positive plate 1032 and the second back plate 102, and a certain space between the negative plate 1031 and the first back plate 101. These spaces can temporarily store water, increase the water storage space and water capacity, and enable the positive and negative plates 1031 to be fully soaked to ensure the electrolysis efficiency.

[0065] In some modes, the support washer 1041 is a fluorine washer, and the third sealing ring 1042 is a silica gel washer.

[0066] The fluorine washer, i.e., the polytetrafluoroethylene washer, has good properties such as corrosion resistance, aging resistance, and non-conductivity, and has a larger hardness than silica gel, thereby having good support performance.

[0067] It can be understood that the support washer 1041 can also be other washers with a certain hardness.

[0068] Preferably, the materials of the first sealing ring 10341, the second sealing ring 10342, and the third sealing ring 1042 can be the same, and all are silica gel washers, and the length, width, and thickness can also be the same specifications.

[0069] The materials of the first sealing ring 10341 and the second sealing ring 10342 can also be the same, but different from that of the third sealing ring 1042.

[0070] It can be understood that the first sealing ring 10341, the second sealing ring 10342, the third sealing ring 1042, and the support washer 1041 are all ring structures, and the shapes can be square, circular, oval, or other shapes, which are not limited herein.

[0071] In some embodiments, as shown in Figure 6 The outer edge of the support washer 1041 protrudes from the outer edge of the third sealing ring 1042, so that the support washer 1041 can effectively support the third sealing ring 1042 when the third sealing ring 1042 is extruded and deformed to extend and increase in size.

[0072] The outer edges of the positive electrode sheet 1032 and the negative electrode sheet 1031 protrude from the outer edge of the third sealing ring 1042, so as to provide support when the third sealing ring 1042 directly attached thereto is deformed by extrusion and extends outward.

[0073] In addition, the outer edges of the positive electrode sheet 1032 and the negative electrode sheet 1031 protrude from the outer edge of the first sealing assembly 1034, so as to provide support when the first sealing assembly 1034 is deformed by extrusion and extends outward.

[0074] In some embodiments, as shown in FIG. 1, the outer edge of the support gasket 1041 protrudes from the outer edge of the third sealing ring 1042 by a protruding distance L1 of 0.5-2 mm. If the protruding distance is too small, the support is not effective when the third sealing ring 1042 is deformed. If the protruding distance is too large, the material is wasted, and the weight is increased. Figure 6 The outer edge of the positive electrode sheet 1032 protrudes from the outer edge of the first sealing assembly 1034 by a protruding distance L2 of 0.5-2 mm, and the outer edge of the negative electrode sheet 1031 protrudes from the outer edge of the first sealing assembly 1034 by a protruding distance L3 of 0.5-2 mm.

[0075] In some embodiments, the thickness of the first sealing ring 10341 and the second sealing ring 10342 is 0.1-1.5 mm.

[0076] The thickness of the third sealing ring 1042 can be 0.1-1.5 mm.

[0077] The thickness of the support gasket 1041 can be 0.1-1.5 mm.

[0078] In some embodiments, as shown in FIG. 1, a first cavity 1035 is formed between the negative electrode sheet 1031 and the proton exchange membrane 1033, and a first titanium mesh (not shown in the figure) is arranged in the first cavity 1035. 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, and a second titanium mesh (not shown in the figure) is arranged in the second cavity 1036. The second titanium mesh is located inside the second sealing ring 10342.

[0079] Figures 9-10 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 fixation reliability of the proton exchange membrane 1033 can be better ensured.

[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 fixation reliability of the proton exchange membrane 1033 can be better ensured.

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

[0082] In specific implementation, in order to facilitate the water in the water inlet joint 1011 to enter the electrolysis body 103 to realize electrolysis and gas escape, as shown in Figure 13 , a first hole 10421 and a second hole 10423 can be provided on the third sealing ring 1042 in direct 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 realize communication, a second communication path 10424 is opened between the second hole 10423 and the inner wall of the third sealing ring 1042 to realize communication, the first hole 10421 is in communication with the water inlet joint 1011, and the second hole 10423 is in communication with the hydrogen joint 1012, so that the water in the water inlet joint 1011 can enter the inside of the third sealing ring 1042 via the first hole 10421, i.e., into the first cavity 1035, and then enter between the positive and negative electrode sheets 1031 via the second negative electrode through hole 10312 on the negative electrode sheet 1031, and permeate or flow to the second positive electrode through hole 10322 to enter the second cavity 1036, to ensure sufficient electrolysis of water, and the hydrogen generated by electrolysis finally enters the second hole 10423 via the second communication path 10424, and is output via the hydrogen joint 1012;

[0083] Similarly, as shown in Figure 14 , a third hole 10425 can also be provided on the third sealing ring 1042 in direct contact with the positive electrode sheet 1032, a third communication path 10426 is opened between the third hole 10425 and the inner wall of the third sealing ring 1042 to realize communication, the third hole 10425 is in communication with the oxygen joint 1013, and the oxygen generated by electrolysis finally enters the third hole 10425 via the third communication path 10426, and is output via the oxygen joint 1013; to avoid mixing of hydrogen and oxygen, the second hole 10423 and the third hole 10425 can be respectively arranged on two sides of the sealing ring.

[0084] It can be understood that the communication of water or gas can also be realized by other forms of communication.

[0085] In some embodiments, as shown in Figures 7-8As shown, the first back plate 101 and the second back plate 102 are connected by the first bolt 105, which penetrates the first back plate 101, the second sealing assembly 104 between the first back plate 101 and the negative plate 1031, the negative plate 1031, the first sealing assembly 1034, the positive plate 1032, the second sealing assembly 104 between the positive plate 1032 and the second back plate 102, and the second back plate 102 in sequence, that is, except that the proton exchange membrane 1033 is not penetrated by the first bolt 105, the edges of other components are penetrated by the first bolt 105, and the nut needs to be locked after penetration.

[0086] The connection is simple and reliable by the first bolt 105, and the clamping force can be adjusted conveniently.

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

[0088] In some embodiments, as shown in Figure 8 As shown, the clamping length L4 of the outer edge of the proton exchange membrane 1033 between the first sealing ring 10341 and the second sealing ring 10342 is 0.5-2 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 high, if the clamping length is too long, the overall size of the proton exchange membrane will inevitably increase under the condition that the exposed area remains unchanged, which will lead to an increase in cost.

[0089] In some embodiments, as shown in Figure 1 , Figure 11 and Figure 12 As shown, the edge of the negative plate 1031 is provided with a first conductive protrusion 10313, and the edge of the positive plate 1032 is provided with a second conductive protrusion 10323, and the first conductive protrusion 10313 and the second conductive protrusion 10323 both extend to the outside of the electrolytic assembly 10.

[0090] The electrolytic body 103 needs to be connected to a circuit assembly, which includes a battery and a circuit board, and the battery supplies power to the circuit board. The positive plate 1032 and the negative plate 1031 can be connected to the corresponding positive and negative poles of the circuit in the circuit board through conductive members such as wires. Through the arrangement of the first conductive protrusion 10313 and the second conductive protrusion 10323, the connection of the positive and negative plates 1031 to the circuit board is more convenient.

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

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

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

[0094] The proton exchange membrane 1033 is a kind of efficient semi-permeable membrane, which has selective permeability and can accurately allow hydrogen ions to pass through while blocking hydroxide ions. Through the proton exchange membrane 1033, hydrogen ions and electrons combine smoothly to generate purer hydrogen gas.

[0095] In the traditional PEM hydrogen production method, a heavy metal coating is coated on the surface of the proton exchange membrane 1033 (Proton Exchange Membrane, PEM) as a catalyst, for example, the proton exchange membrane 1033 is coated with a catalyst-iridium oxide near the anode side; the other side is coated with a catalyst-platinum carbon. When water electrolysis is performed in this way, the heavy metal material is easy to fall off and enter the user's body with the drinking action, and such heavy metals are toxic and can adversely affect the human body. In order to avoid such effects, the proton exchange membrane 1033 in the electrolysis body 103 of the present embodiment does not have a catalyst coating, and the negative electrode sheet 1031 and the positive electrode sheet 1032 are both titanium electrode sheets made of titanium material, and the electrolysis hydrogen is realized by the electrolysis body 103.

[0096] In addition, due to the good conductivity and strong stability of the titanium electrode, when the titanium electrode is subjected to direct current voltage impact for electrolysis, the efficient and stable operation of the electrolysis operation can also be effectively guaranteed.

[0097] The electrolysis principle of the above electrolysis assembly 10 is as follows: after power-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 through the proton exchange membrane 1033, so that the proton exchange membrane 1033 is soaked, and further flows to the positive electrode sheet 1032, the water in the electrolysis assembly 10 is electrolyzed to produce hydrogen and oxygen, that is, the electrons of the negative electrode enter the water and react with the hydrogen ions to produce hydrogen, and the positive electrode accepts electrons from the hydroxyl radical to become oxygen. The hydrogen generated is discharged through the first negative electrode through hole 10311 and finally enters the hydrogen joint 1012 for discharge, and the oxygen is discharged 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 of the above embodiment can be square, circular or other shapes.

[0099] The electrolysis assembly of the above embodiment has good sealing performance, which can effectively guarantee the electrolysis efficiency; the overall structure is compact, which is convenient for assembly and maintenance.
