[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figure 1-3 This utility model provides an embodiment of an air purification device for laboratory ventilation ducts, comprising a housing 1, a guide groove 4 fixedly connected to the bottom of the housing 1 for collecting dust, a rotating door 5 rotatably connected to the left end of the guide groove 4, a rotating block 6 rotatably connected to the bottom end of the rotating door 5, and a locking block 7 provided at the bottom end of the rotating block 6. The rotating door 5 is limited by the cooperation of the rotating block 6 and the locking block 7. The locking block 7 is fixedly connected to the bottom left end of the guide groove 4. A filter plate 9 for filtering dust is provided in the middle of the interior of the housing 1. A protruding strip 15 is fixedly connected to both the top and bottom ends of the filter plate 9. The protruding strip 15 has a concave-convex design. A movable plate 11 is sleeved on the outside of the filter plate 9. A screw 14 is threadedly connected to the front of the top end of the movable plate 11. The left end of screw 14 passes through the housing 1, and a crank is fixedly connected to the left end of screw 14. By turning the crank, screw 14 can be rotated. Screw 14 is rotatably connected to the inner wall of housing 1. A limit rod 10 is slidably connected to the rear side of the top of moving plate 11. The limit rod 10 can limit the moving plate 11. The limit rod 10 is fixedly connected to the inner wall of housing 1. A moving groove is opened in the middle of moving plate 11. Filter plate 9 passes through the moving groove. Multiple moving holes are opened at the top and bottom of the inner wall of the moving groove. Vibrating block 12 is set in the moving hole. A spring 13 is set at the end of vibrating block 12 away from the moving groove. The spring 13 can reset vibrating block 12. One end of spring 13 is connected to vibrating block 12, and the other end of spring 13 is connected to moving plate 11.
[0025] Reference Figure 3-5The filter plate 9 has slide rails 8 slidably connected to both its left and right ends. The slide rails 8 are fixedly connected to the inner wall of the housing 1. The slide rails 8 allow for the disassembly and installation of the filter plate 9, facilitating maintenance by staff. A fan body 3 is located at the front center of the housing 1. A ventilation pipe 2 is fixedly connected to the rear center of the housing 1.
[0026] Working principle: First, air and dust are drawn into the housing 1 and filtered through the filter plate 9. When the filter plate 9 needs to be cleaned, the screw 14 is rotated to move the movable plate 11 on its outer wall. When the movable plate 11 moves, the vibrating block 12 on the movable plate 11 moves along the protruding strips 15 at the top and bottom of the filter plate 9. When the vibrating block 12 moves to the protruding position, the vibrating block 12 compresses the spring 13. When the vibrating block 12 moves to the concave position, the spring 13 pushes the vibrating block 12. This process repeats, thereby vibrating the filter plate 9 through the vibrating block 12, causing the dust accumulated on the filter plate 9 to be shaken off. The shaken dust falls into the guide groove 4. Then, by rotating the rotating block 6 and opening the rotating door 5, the dust in the guide groove 4 is cleaned out.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
