[0021] 2. The installation spring drives the installation button to fully engage with the installation hole, thus ensuring quick installation and disassembly, facilitating easy cleaning of the filter screen, reducing damage caused by screw removal and assembly, and resulting in a long service life.

[0022] 3. The use of positioning screws that pass through the through holes and are threaded into the positioning screw holes ensures a good installation effect for the filter screen. The filter screen itself does not need to be disassembled, and the screws only need to be disassembled when replacing the filter screen. This ensures a good overall installation effect while facilitating the overall installation and disassembly, resulting in a stable installation effect. Attached Figure Description
