The specific content is as follows:

[0020] 1. Installation components are provided at the joints between the two end covers and the tank body. The gas-liquid mixture enters the inside of the shunt pipe through the liquid inlet pipe and is sprayed out through the nozzle. Then, the liquid moves downward under the action of gravity and is discharged through the liquid outlet pipe, while the gas is discharged through the gas outlet pipe. The gas can be filtered through the filter screen to improve the purity of gas-liquid separation. When it is necessary to disassemble the end cover to remove the filter screen for cleaning, pull the two groups of handles to drive the movable plate to slide on the support rod, so as to compress the return spring. As a result, the limit block on the movable plate is disengaged from the limit groove on the movable rod, causing the movable rod to lose its limit. The telescopic spring can restore its deformation, enabling the movable rod to lose its limit, and separating the end cover from the tank body. When installing and fixing the end cover, align the end cover with the tank body, insert the two groups of movable rods on the first connecting ring into the second connecting ring. Then, push the movable rod to move and compress the telescopic spring. After the movable rod moves, since one end is arc-shaped, the movement of the movable rod can push the limit block to move, causing the movable plate to slide on the support rod and compress the return spring. The movement of the movable rod aligns the limit groove with the limit block, and the return spring can restore its deformation, causing the limit block to engage with the limit groove to limit the movable rod, thereby limiting the end cover. Moreover, the compressed telescopic spring can squeeze the sealing ring to deform, ensuring the reliability of the end cover installation. The installation components facilitate the disassembly and assembly of the end cover by the user, facilitate opening the tank body, and further facilitate the subsequent removal of the filter screen for cleaning, making it convenient for the user to operate and improving the convenience and practicality;

[0021] 2. Two sets of positioning components are symmetrically arranged inside the two mounting rings. After the end cover is opened, when the mounting ring is removed, the sliding rod can be pushed to move. The sliding rod slides on the rotating sleeve so that the positioning block on the mounting block is disengaged from the positioning groove on the fixed ring, so that the mounting block loses its limit. The rotating sliding rod drives the rotating sleeve to rotate inside the fixed sleeve. While the rotating sleeve rotates, it is limited by the limit ring and the annular groove. After the sliding rod is rotated, the mounting block is aligned with the through groove on the fixed ring. The sliding rod compression spring can be loosened to restore the deformation, so that the mounting ring can lose its limit, and then the mounting ring can be removed. In order to clean the filter and avoid clogging, when installing the mounting ring, fit the mounting ring and the fixing ring together with the sliding rod and insert it into the through slot, push the sliding rod to move so that the mounting block leaks out of the through slot, and then rotate the sliding rod to stagger the mounting block and the through slot, so that the positioning block on the mounting block is aligned with the positioning slot, and the sliding rod is released to engage the positioning block with the positioning slot under the action of the compression spring, so that the mounting block is limited, and then the mounting ring is limited, completing the installation of the mounting ring. The positioning assembly is convenient for users to disassemble the mounting ring, which makes it easier to clean the filter and improves the convenience of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Working principle: Before using this hydrogen and liquid separation device for water electrolysis, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 5As shown in the figure, installation components 2 are provided at the connections between the two end caps 102 and the tank body 1. The gas-liquid mixture enters the interior of the shunt pipe 104 through the liquid inlet pipe 103 and is ejected through the nozzle. Then, the liquid moves downward under the action of gravity and is discharged through the liquid outlet pipe 106, while the gas is discharged through the gas outlet pipe 105. Filtration can be carried out through the filter screen 109 to improve the purity of gas-liquid separation. When it is necessary to disassemble the end cap 102 to remove the filter screen 109 for cleaning, two groups of handles 212 are pulled to drive the movable plate 209 to slide on the support rod 206, so that the return spring 207 can be compressed. As a result, the limiting block 210 on the movable plate 209 is disengaged from the limiting groove 211 on the movable rod 204, causing the movable rod 204 to lose its limit. The telescopic spring 205 can restore its deformation, enabling the movable rod 204 to lose its limit, and the end cap 102 can be separated from the tank body 1. When installing and fixing the end cap 102, the end cap 102 is aligned with the tank body 1, so that the two groups of movable rods 204 on the first connecting ring 202 are inserted into the second connecting ring 203. Then, the movable rod 204 can be pushed to move and compress the telescopic spring 205. After the movable rod 204 moves, since one end is arc-shaped, the movement of the movable rod 204 can push the limiting block 210 to move, causing the movable plate 209 to slide on the support rod 206 and compress the return spring 207. The movement of the movable rod 204 aligns the limiting groove 211 with the limiting block 210, and the return spring 207 can restore its deformation, enabling the limiting block 210 to engage with the limiting groove 211 to limit the movable rod 204, thereby limiting the end cap 102. Moreover, the compressed telescopic spring 205 can squeeze the sealing ring 201 to deform, ensuring the reliability of the installation of the end cap 102. The installation component 2 facilitates the disassembly and assembly of the end cap 102 by the user, facilitates the opening of the tank body 1, and thus facilitates the subsequent removal of the filter screen 109 for cleaning, which is convenient for the user to operate and improves the convenience and practicality;

[0032] Two groups of positioning components 3 are symmetrically arranged inside the two mounting rings 108. After the end cover 102 is opened, when the mounting ring 108 is removed, the sliding rod 301 can be pushed to move. The sliding rod 301 slides on the rotating sleeve 303 so that the positioning block 309 on the mounting block 308 is disengaged from the positioning groove 310 on the fixed ring 107, so that the mounting block 308 loses its limit. The rotating sliding rod 301 drives the rotating sleeve 303 to rotate inside the fixed sleeve 304. While the rotating sleeve 303 rotates, it is limited by the limiting ring 305 and the annular groove 306. After the sliding rod 301 is rotated, the mounting block 308 is aligned with the through groove 307 on the fixed ring 107. The sliding rod 301 can be loosened to compress the spring 302 to restore the deformation, so that the mounting ring 108 can lose its limit, and then the mounting ring 108 can be removed. The filter screen 109 can be cleaned to avoid clogging. When installing the mounting ring 108, the mounting ring 108 and the fixing ring 107 are fitted with the sliding rod 301 and inserted into the through groove 307, and the sliding rod 301 is pushed to move so that the mounting block 308 leaks out of the through groove 307. Then, the sliding rod 301 is rotated to stagger the mounting block 308 and the through groove 307, so that the positioning block 309 on the mounting block 308 is aligned with the positioning groove 310, and the sliding rod 301 is released. Under the action of the compression spring 302, the positioning block 309 is engaged with the positioning groove 310, so that the mounting block 308 is limited, and then the mounting ring 108 is limited, and the installation of the mounting ring 108 is completed. The positioning component 3 is convenient for users to disassemble the mounting ring 108, and then it is convenient to clean the filter screen 109, thereby improving the convenience of use.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
