When the rotating rod 69 rotates, it drives the threaded rod 610 to rotate. When the threaded rod 610 rotates in the threaded hole 65, it drives the pressing plate a63 and the pressing plate b64 to move on the outer side wall of the limiting rod 62. Then take out the filter cotton 67 attached to one side of the mounting frame 61 for cleaning. Then rotate the clamping plate b15 counterclockwise. After the rotation is completed, open the inspection door b13, and then the worker enters the inspection door b13 to replace the primary filter 7, thus completing the cleaning of the device.

[0030] It should be noted that: Through the slide rail 3, the loading and unloading of the diamond yarn grid 55 can be facilitated. Through the grid frame 4, larger garbage can be effectively blocked from entering the bin body a1. Through the filter assembly a5, smaller garbage or mosquitoes can be effectively blocked from entering the bin body b2, so as to effectively improve the smoothness of fresh air entering, and at the same time, it is more convenient to clean the attached smaller garbage, thereby improving the flow rate of fresh air entering. Through the filter assembly b6, large dust particles can be effectively blocked from entering, and it is more convenient to disassemble, clean or replace the filter cotton 67. Through the primary filter 7, small particle dust can be effectively blocked from entering, thereby improving the quality of fresh air after entering. Through the storage tube 52, it is convenient to store the diamond yarn grid 55 wound outside the winding barrel 53. Through the rotating handle 54, it is convenient to rotate the winding barrel 53. Through the multiple clamping blocks 51 and the storage tube 52, the winding barrel 53, and the slide rail 3, the diamond yarn grid 55 can be taken out for cleaning more conveniently. Through the mounting frame 61, the pressing plate a63, and the pressing plate b64, the flatness of the filter cotton 67 during installation and laying can be improved. Through the limiting rod 62, the smoothness of the pressing plate a63 and the pressing plate b64 during movement can be improved.
