[0002] The electrolytic cell is the core component in the hydrogen generator. Figures 1 to 3 The electrolytic cell comprises a first end plate 1 and a second end plate 2 and an electrolytic cell body arranged between the first end plate 1 and the second end plate 2.

[0003] The upper end of the first end plate 1 and the second end plate 2 is respectively provided with an oxygen outlet 11 and a hydrogen outlet 12, and the lower end of the first end plate 1 and the second end plate 2 is provided with a liquid inlet 13.

[0004] The electrolytic cell body comprises an anode plate 3, a cathode plate 4, a bipolar plate 5, a cylinder frame 6, a diaphragm 7 and a sealing gasket 8.

[0005] The anode plate 3 is used for connecting the positive pole of the direct current power supply, and the cathode plate 4 is used for connecting the negative pole of the direct current power supply.

[0006] The outer periphery of the anode plate 3, the cathode plate 4 and the bipolar plate 5 is provided with the cylinder frame 6, and the upper end of each cylinder frame 6 is provided with a cylinder frame oxygen hole 61 and a cylinder frame hydrogen hole 62.

[0007] The upper end of each cylinder frame 6 is provided with an electrolyte cutout 66, and the electrolyte cutout 66 is communicated with the cylinder frame electrolyte hole 63.

[0008] The lower end of each cylinder frame 6 is provided with an electrolyte cutout 66, and the electrolyte cutout 66 is communicated with the cylinder frame electrolyte hole 63.

[0009] In assembling the electrolytic cell, first, the screw rod 9 is threaded through the mounting hole 14 on the first end plate 1 and the second end plate 2, and then the nut 10 is screwed on both ends of the screw rod 9, so that the first end plate 1 and the electrolytic cell body and the second end plate 2 are pressed together. After the electrolytic cell is assembled, the oxygen cutout 64, the cylinder frame oxygen hole 61, the diaphragm oxygen hole 71, the gasket oxygen hole 81, and the oxygen outlet 11 are connected to form an oxygen passage, the hydrogen cutout 65, the cylinder frame hydrogen hole 62, the diaphragm hydrogen hole 72, the gasket hydrogen hole 82, and the hydrogen outlet 12 are connected to form a hydrogen passage, and the electrolyte cutout 66, the cylinder frame electrolyte hole 63, the diaphragm electrolyte hole 73, the gasket electrolyte hole 83, and the liquid inlet 13 are connected to form an electrolyte passage.

[0056] Embodiment:

[0057] A hydrogen production machine comprises an electrolytic cell. Referring to Figures 4 to 10 , the electrolytic cell comprises a first end plate 1 and a second end plate 2, and an electrolytic cell body arranged between the first end plate 1 and the second end plate 2.

[0058] The first end plate 1 is uniformly provided with a plurality of insertion holes 15 around the circumference, and in this embodiment, eight insertion holes 15 are provided.

[0059] The first end plate 1 has a cylinder seat 16 on the side away from the second end plate 2, and the cylinder wall of the cylinder seat 16 is uniformly provided with eight sliding grooves 161 around the circumference, and a locking rod 17 is placed in the sliding grooves 161, and the locking rod 17 is in sliding fit with the sliding grooves 161 along the radial direction of the cylinder seat 16. One end of the locking rod 17 located in the cylinder seat 16 is connected to the inner wall of the cylinder seat 16 by an elastic member, and the elastic member can be a spring 171. One end of the locking rod 17 located in the cylinder seat 16 is provided with a slope 172. The end of the cylinder seat 16 is provided with a threaded hole 162, and a threaded stud 18 is arranged in the threaded hole 162, and the threaded stud 18 is in threaded connection with the threaded hole 162, and one end of the threaded stud 18 located in the cylinder seat 16 abuts against the slope 172.

[0060] When assembling the locking rod 17, the spring 171, the cylinder seat 16 and the first end plate 1, first, the spring 171 is welded and fixed at one end of the locking rod 17 provided with the slope 172; then, the locking rod 17 is placed in the sliding groove 161, so that one end of the locking rod 17 welded with the spring 171 is inserted into the inside of the cylinder seat 16, and the spring 171 abuts against the inner wall of the cylinder seat 16; finally, the cylinder seat 16 is welded and fixed at the middle part of the first end plate 1, so that the locking rod 17, the spring 171, the cylinder seat 16 and the first end plate 1 are assembled.

[0061] When the threaded stud 18 is screwed downwardly into the threaded hole 162, one end of the threaded stud 18 located in the cylinder seat 16 pushes the slope 172 on the locking rod 17 downwardly, so that the slope 172 on the locking rod 17 moves in the direction close to the inner wall of the cylinder seat 16 against the elastic force of the spring 171, and at the same time, the locking rod 17 also slides to the outside of the sliding groove 161, so that the length of the locking rod 17 extending out of the cylinder seat 16 increases.

[0062] When the stud 18 is screwed upward from the screw hole 162, the end of the lock rod 17 provided with the slope 172 moves to the center position of the cylinder seat 16 under the elastic force of the spring 171, so that the slope 172 keeps abutting with the lower end of the stud 18, and at the same time, the length of the lock rod 17 outside the cylinder seat 16 is reduced.

[0063] In order to facilitate the operation of the stud 18, the end of the stud 18 outside the cylinder seat 16 is welded with a handle 181.

[0064] In order to reduce the weight, the middle part of the stud 18 is provided with a weight-reducing groove 182.

[0065] The second end plate 2 is circumferentially welded with eight insertion rods 21, which are used for insertion fitting with the insertion holes 15 on the first end plate 1. The insertion rod 21 is provided with a lock hole 211, and the lock hole 211 is provided with a slope wall 2111 on the side away from the second end plate 2. The end of the lock rod 17 outside the cylinder seat 16 can abut with the slope wall 2111.

[0066] The working principle of the embodiment is as follows:

[0067] (1) When assembling the electrolytic cell:

[0068] Firstly, the insertion rod 21 on the second end plate 2 is inserted into the insertion hole 15 on the first end plate 1, so that the lock hole 211 on the insertion rod 21 is exposed from the side of the first end plate 1 away from the second end plate 2.

[0069] Then, the stud 18 is screwed downward from the screw hole 162, and the end of the stud 18 inside the cylinder seat 16 pushes the slope 172 on the lock rod 17 downward, so that the slope 172 on the lock rod 17 approaches the inner wall of the cylinder seat 16 against the elastic force of the spring 171, and at the same time, the lock rod 17 also slides to the outside of the sliding groove 161. The end of the lock rod 17 outside the cylinder seat 16 is inserted into the lock hole 211, and the lock rod 17 abuts on the slope wall 2111 of the lock hole 211. As the lock rod 17 continues to be inserted into the lock hole 211, the lock rod 17 pushes the slope wall 2111, so that the insertion rod 21 is further exposed from the insertion hole 15, the distance between the first end plate 1 and the second end plate 2 is reduced, and the first end plate 1 and the electrolytic cell body and the second end plate 2 are pressed together, thereby realizing the assembly of the electrolytic cell.

[0070] (2) When disassembling the electrolytic cell:

[0071] Firstly, the stud 18 is screwed upward from the screw hole 162, and the end of the lock rod 17 provided with the slope 172 moves to the center position of the cylinder seat 16 under the elastic force of the spring 171, so that the slope 172 keeps abutting with the lower end of the stud 18, and at the same time, the end of the lock rod 17 outside the cylinder seat 16 is withdrawn from the lock hole 211.

[0072] Then, the second end plate 2 is moved away from the first end plate 1, so that the insertion rod 21 on the second end plate 2 is withdrawn from the insertion hole 15 on the first end plate 1, that is, the electrolytic cell is disassembled.

[0073] Through the above working principle, it can be known that the embodiment has the following effects:

[0074] Compared with the background art, the embodiment only needs to rotate a stud 18 when disassembling the electrolytic cell, so that the operation can be simplified, and the efficiency of disassembling the electrolytic cell can be improved.

[0075] After improving the efficiency of disassembling the electrolytic cell, the efficiency of replacing the anode plate or the cathode plate or the bipolar plate in the electrolytic cell body can be improved, and the maintenance is facilitated.

[0076] In addition, because the insertion hole 15 is provided with an inclined hole wall 2111 on the side away from the second end plate 2, when the lock rod 17 is inserted into the lock hole 211, the lock rod 17 can push the insertion rod 21 provided with the inclined hole wall 2111 to move upward, so that the second end plate 2 is close to the first end plate 1, and the first end plate 1 and the second end plate 2 can tighten the electrolytic cell body, and the reliability of assembling the electrolytic cell together can be improved.

[0077] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and the equivalent technology, the present application also intends to include these modifications and variations.
