A sliding plate 23 is slidably connected inside the sliding groove 21. A gear 24 is rotatably connected between the sliding groove 20 and the sliding groove 21 at the bottom position of the center of the mounting plate 14. A toothed opening 28 is provided on the opposite side of the sliding plate 22 and the sliding plate 23. The front and rear sides of the gear 24 pass through the interior of the two toothed openings 28 and mesh with the toothed openings 28. The opposite sides of the sliding plate 22 and the sliding plate 23 both pass through to the outside of the mounting plate 14.

[0015] One side of the housing 1 is connected to an air outlet pipe 4. A buckle plate 16 is fixedly connected to the center of the bottom inside the housing 1. The bottom of filter screen 17, filter screen 2 18 and filter screen 3 19 are fixedly connected to mounting plate 2 15. The bottom of mounting plate 2 15 extends through the interior of buckle plate 16 and is snapped into buckle plate 16.

[0016] The tops of sliding plate 1 22 and sliding plate 23 are in contact with the top of the inside of housing 1.

[0017] A rotating rod 25 is fixedly connected to the top of the gear 24. The top of the rotating rod 25 extends through to the outside of the mounting plate 14 and is fixedly connected to a rotating plate 26.

[0018] The top of the housing 1 is provided with slots 2 13 on both sides of the top of the mounting slot 2 12. The mounting plate 14 is fixedly connected to both sides with a card plate 2 27. The side of the card plate 2 27 away from the mounting plate 14 extends into the interior of the slot 2 13 and engages with the slot 2 13.

[0019] A mounting groove 5 is provided at the center of the other side of the housing 1. An air inlet pipe 6 is snapped into the inside of the mounting groove 5. A slot 7 is provided on one side of the housing 1 above and below the mounting groove 5. An external plate 8 is fixedly connected to the center of the top and bottom of the air inlet pipe 6. A snap plate 9 is fixedly connected to one side of the external plate 8. One side of the snap plate 9 extends into the inside of the slot 7 and snaps into the slot 7.

[0020] An inner plate 10 is fixedly connected to the top and bottom positions on one side of the shell 1. A fixing bolt 11 is threadedly connected to one side of the outer plate 8. One side of the fixing bolt 11 passes through the card plate 9 and the inner plate 10 in sequence and is threadedly connected to the inner plate 10.

[0021] Working principle: When the air filter starts working, the induced draft fan 2 starts, generating suction to draw outside air into the housing 1 through the air inlet pipe 6. The air entering the housing 1 first passes through filter screen 17, which mainly intercepts large particles and dust. Then, the air passes through filter screen 18, which further filters smaller particles and harmful substances. Finally, the air passes through filter screen 19, which typically has a finer filtration capacity, capable of intercepting tiny bacteria, viruses, and other microorganisms, and also has antibacterial properties. Finally, the air passes through the rear filter screen 3 and is discharged from the air outlet pipe 4. For disassembly, use... The user first rotates the rotating plate 26, which drives the rotating rod 25 to rotate. The rotation of the rotating rod 25 further drives the gear 24 to rotate. Since the gear 24 meshes with the teeth 28 of the sliding plate 1 22 and the sliding plate 23, the rotation of the gear 24 will cause the sliding plate 1 22 and the sliding plate 23 to move into the mounting plate 14. When the sliding plate 1 22 and the sliding plate 23 are completely moved into the mounting plate 14, they are no longer in contact with the inner top of the housing 1, thereby releasing the fixing of the mounting plate 14. The user can easily remove the mounting plate 14 from the mounting slot 2 12 at the top of the housing 1.

[0022] In summary, this antibacterial air filter, through the snap-fit ​​structure between mounting slot 2 12 and mounting plate 14, and the snap-fit ​​structure between mounting plate 2 15 and snap-fit ​​plate 16, enables quick installation and removal of the filter screen. Users can easily remove or install mounting plate 14 and its filter screen from housing 1 without the need for complex tools, greatly simplifying the maintenance process. Simultaneously, the snap-fit ​​design between snap-fit ​​plate 27 and slot 2 13 further enhances the stability of mounting plate 14 within housing 1, ensuring the reliability of the filter screen during use. The multi-layer filter structure allows different layers to capture particles of different sizes, thereby improving filtration efficiency. The linkage mechanism between sliding plate 1 22, sliding plate 23, and gear 24 allows users to easily adjust the spacing between the filter screens to adapt to different filtration needs. This design not only improves the flexibility of the filter screen but also helps extend its service life and reduce replacement frequency.
