The bottom of the pressing rod 302 is in contact with the top of the filter screen 204. The filter assembly 2 and the disassembly assembly 3 are designed to prevent the filter components from becoming clogged during use. At the same time, the filter structure can be disassembled and cleaned during use, which avoids affecting the normal filtration operation of the structure in subsequent use and improves the ease of use of the structure.

[0029] See Figure 1The base 1 has an adjustment component 4 at its bottom. The adjustment component 4 includes round tubes 400 fixedly installed at the four corners of the bottom of the base 1. The bottom of the round tubes 400 is threadedly connected to a threaded rod 401. A positioning plate 402 is fixedly installed at the bottom of the threaded rod 401. The positioning plate 402 has positioning holes, which are oblong holes. The lower surface of the positioning plate 402 has anti-slip textures. The filter component 2 and the disassembly component 3 are provided to prevent the filter components from becoming clogged during use. At the same time, the filter structure can be disassembled and cleaned during use, which can prevent the normal filtration operation of the structure from being affected during subsequent use, thus improving the ease of use of the structure.

[0030] See Figure 4 A plug rod 205 is fixedly installed at the bottom of the filter screen 204. The bottom of the plug rod 205 passes through the positioning ring 203 and extends to the outside of the positioning ring 203. The positioning ring 203 has a rod hole for the plug rod 205 to pass through, and the inner wall of the rod hole is slidably connected to the surface of the plug rod 205. The plug rod 205 and the rod hole facilitate the limiting of the filter screen 204 on the plug rod 205 during use, and also facilitate the subsequent disassembly and installation of the filter screen 204, thereby improving the installation stability of the filter screen 204.

[0031] See Figure 2 A buffer spring 206 is arranged around the surface of the plug rod 205. The top of the buffer spring 206 is fixedly connected to the bottom of the filter screen 204, and the bottom of the buffer spring 206 contacts the top of the positioning ring 203. The buffer spring 206 facilitates the reset of the filter screen 204 during use, thereby improving the ease of cleaning the filter screen 204.

The hexagonal nut 6 has a threaded groove inside. The connecting pipe 5 and the hexagonal nut 6 are designed to facilitate tightening and positioning during use, thereby improving the ease of use of the structure.

[0035] During operation, when the installation height of the structure needs to be adjusted, rotate the threaded rod 401 on the positioning plate 402, then adjust the support height of the base 1, and then position and connect it through the positioning plate 402. Then connect the hexagonal nut 6 to the air outlet and connect it to the air inlet through the connecting ring 303. Then the gas enters the interior of the cylinder 200 through the vertical pipe 301. The gas first passes through the filter screen 204. When the gas impacts the filter screen 204, it will cause the filter screen 204 to shake, thereby preventing particulate impurities from getting stuck in the mesh. Then it passes through the adsorption screen 202 for adsorption and filtration. After filtration, the gas can be discharged through the connecting pipe 5.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
