When it is necessary to install the filter screen 12, first, the sliding rod 311 is slid counterclockwise along the arc-shaped groove 310, the rotating ring 312 is rotated in the same direction, so that the path groove 306 gradually approaches the position outside the connecting rod 307 to contact, thereby driving the connecting rod 307 and the positioning block 304 to slide, and at the same time, the positioning block 304 moves outwardly into the through groove 303, and the vortex spring 305 is deformed, then the butt joint ring 308 at the top of the filter screen 12 is inserted into the inside of the fixed ring 301, and the fixed ring 301 is rotated to make the positioning groove 309 correspond to the position of the through groove 303, then the sliding rod 311 is loosened, so that the vortex spring 305 rebounds to drive the rotating ring 312 to rotate clockwise, so that the path groove 306 gradually approaches the position inside the sliding rod 311 to contact, thereby driving a group of positioning blocks 304 to move inwardly and insert into the corresponding positioning groove 309, thereby achieving the effect of installing the filter screen 12. Similarly, the filter screen 12 can also be disassembled and replaced according to the above-mentioned manner. The above-mentioned installation and disassembly process is simple and convenient, thereby achieving the effect of convenient replacement of the filter screen 12.
