Figure 1-Figure 5A retractable air filtering structure, characterized in that: it includes a support plate 1; a shell 2 is fixedly installed on the top of the support plate 1, an outer filter component 3 is fixedly installed on the top of the support plate 1, a telescopic rod 4 is fixedly installed on the top of the support plate 1, the outer filter component 3 is located inside the shell 2, the shell 2 can protect the outer filter component 3, the telescopic rod 4 is located inside the outer filter component 3, an inner filter component 5 is fixedly installed on the top of the telescopic rod 4, an ultraviolet lamp 6 is fixedly installed at the center of the top of the support plate 1, a blower 7 is fixedly installed on the top wall of the shell 2, a bellows 8 is fixedly installed on the bottom end of the blower 7, one end of the blower 7 extends to the outside of the shell 2, the blower 7 can pour the gas inside the shell 2 to the outside, the bellows 8 is located outside the inner filter component 5, the bellows 8 The gap between the top of the inner filter assembly 5 and the top wall of the outer shell 2 after telescoping can be blocked to prevent air from being discharged directly without being filtered. The bottom end of the support plate 1 is slidably connected to a sliding rod 9, and a buffer spring 10 is fixedly installed on the surface of the sliding rod 9. An arc groove is provided at the bottom end of the support plate 1, and the sliding rod 9 is slidably connected to the inside of the arc groove. The end of the buffer spring 10 away from the sliding rod 9 is fixedly installed on the inner wall of the arc groove. The center of the bottom end of the support plate 1 is rotatably connected to a rotating ring 11, and a pull rope 12 is wound around the surface of the rotating ring 11. There are four groups of pull ropes 12, each group has two, one end of one pull rope 12 away from the rotating ring 11 is fixedly connected to the bottom end of the sliding rod 9, and the two ends of the other pull rope 12 are respectively fixedly connected to the top of the sliding rod 9 and the surface of the telescopic rod 4.

[0025] Reference Figure 2 and Figure 6 A vertical rod 13 is fixedly installed on the top of the support plate 1, and a sliding ring 14 is slidably connected to the surface of the vertical rod 13. A convex rod 15 is fixedly installed on one end of the sliding ring 14 close to the center of the support plate 1. There are four vertical rods 13 and they are distributed circumferentially. The convex rod 15 is in adaptive contact with the outer surface of the outer filter component 3. When the sliding ring 14 drives the convex rod 15 to move, large-volume impurities on the surface of the support plate 1 are scraped off.

[0026] Working principle: After the operator turns on the ultraviolet lamp 6 and the blower 7, the outer filter component 3 and the inner filter component 5 filter the air and discharge the filtered gas to the outside of the housing 2 through the blower 7, thereby filtering the air.

[0027] When the height of the filter structure needs to be adjusted, the operator can rotate the rotating ring 11 to pull the pull rope 12. At this time, the pull rope 12 will pull the sliding rod 9 to compress the buffer spring 10 inside the arc groove and move, and at this time the sliding rod 9 will pull another pull rope 12, so that the pull rope 12 pulls the telescopic rod 4 and shortens the telescopic rod 4. At this time, the telescopic rod 4 will drive the inner filter assembly 5 to move downward. At this time, the inner filter assembly 5 moves downward to the inside of the outer filter assembly 3, thereby achieving the purpose of adjusting the height of the filter structure. When the position of the inner filter assembly 5 is adjusted, the operator can lengthen the bellows 8 so that the bottom end of the bellows 8 is attached to the top of the inner filter assembly 5 to prevent unfiltered air from passing through the gap between the inner filter assembly 5 and the top wall of the outer shell 2.

[0028] The operator can also remove the outer shell 2, and then push the sliding ring 14 up and down to make the sliding ring 14 slide on the surface of the vertical rod 13. When the sliding ring 14 moves, it will drive the protruding rod 15 to move on the surface of the outer filter component 3. At this time, the protruding rod 15 can scrape off large-volume impurities on the surface of the outer filter component 3.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
