When the first slide 50 slides out, the protrusion 52 pushes the lifting ring 46 and the third fixing frame 47 to move up to the initial height, and the magnet block 49 drives the iron block 44, the second guide column 42 and the movable ring 7 to move up through the magnetic force, and the second compression spring 45 is in a compressed state. The second compression spring 45 applies pressure to the movable ring 7. When the magnet block 49 moves up to the highest position, the second compression spring 45 pushes the movable ring 7, the second guide column 42 and the iron block 44 to move down, and the iron block 44 is no longer magnetically attracted to the magnet block 49. Finally, the movable ring 7 and the filter screen 8 are lowered to the initial height, and the iron block 44 and the support portion 4 3, the dust on the filter screen 8 is shaken off from the filter screen 8 due to inertia, and the dust falls into the collection box 58, and the dust is collected by the collection box 58 to prevent the dust from falling into the external environment again. When it is necessary to clean the dust collected in the collection box 58, the staff drives the movable plate 63 to move downward, and the tension spring 64 is in a tensioned state to make the limit column 62 disengage from the mounting block 61, thereby releasing the limitation on the position of the mounting block 61, and the staff drives the collection box 58 to move horizontally to make the mounting block 61 disengage from the second slide groove 60, and the collection box 58 can be removed.

[0040] Working principle: The air outside the cabinet 1 is drawn into the cabinet 1 through the filter 8 through the air intake heat dissipation mechanism on the first support ring 26, so as to achieve the purpose of heat dissipation inside the cabinet 1, and the dust in the air is filtered through the filter 8 to prevent the dust from being drawn into the cabinet 1 and causing pollution. When it is necessary to clean the filter 8 located below the first support ring 26, the turntable 4 is driven to rotate through the one-way damping drive structure, and the turntable 4 moves the filter 8 to be cleaned to the right below the second support ring 27, and the filter 8 originally located right below the second support ring 27 is moved to the right below the first support ring 26. After the movable ring 7 is driven to move up to a preset height by the lifting and shaking cleaning component, the elastic support member drives the movable ring 7 and the filter 8 to descend to the initial height, so that the dust on the filter 8 is shaken off due to inertia, and the dust on the filter 8 can be cleaned, reducing the influence of the blockage of the filter 8 on the air intake and heat dissipation of the cabinet 1, thereby ensuring the dustproof and ventilation effects of the filter 8;

[0041] The first compression spring 21 is initially in a compressed state, and the first compression spring 21 applies an upward pressure to the movable frame 19 and the movable sleeve 10, so that the second arc damping plate 13 is tightly attached to the first arc damping plate 12, and the second bevel gear 24 is driven to rotate by the motor 23, and the second bevel gear 24 drives the first rotating shaft 9 to rotate through the first bevel gear 22, and the first rotating shaft 9 drives the movable sleeve 10 and the mounting ring 11 to rotate through the guide block 18, and the mounting ring 11 drives the second arc damping plate 13 to rotate through the first positioning column 14, and the second arc damping plate 1 The first arc damping plate 12, the second positioning column 15 and the turntable 4 are driven to rotate synchronously by friction force, and the inclined surface on the slider 66 slides on the inner wall of the third slide groove 67. As the turntable 4 continues to rotate, the slider 66 finally slides out of the third slide groove 67, and the third compression spring 68 is in a compressed state. When the turntable 4 rotates to a preset angle, the third slide groove 67 moves to one side of the corresponding slider 66, and the third compression spring 68 drives the end of the slider 66 to slide into the third slide groove 67. When the motor 23 drives the second bevel gear 24 to rotate in the opposite direction, the slider 66 slides out of the third slide groove 67. When the first arc damping plate 12 and the second arc damping plate 13 need to be replaced, the staff drives the mounting ring 11 and the movable sleeve 10 to move downward, and the guide block 18 slides in the guide groove 17. The second arc damping plate 13 and the first arc damping plate 12 move downward with the mounting ring 11, and the first compression spring 21 is in a compressed state. Finally, the second arc damping plate 13 and the first arc damping plate 12 move downward with the mounting ring 11. The second positioning column 15 is separated from the positioning groove 16 on the first arc damping plate 12, and the staff drives the first arc damping plate 12 to move horizontally so that the first arc damping plate 12 is no longer located on the top of the second arc damping plate 13, and the staff then drives the second arc damping plate 13 to move upward so that the first positioning column 14 is separated from the positioning groove 16 on the second arc damping plate 13, and the removal of the second arc damping plate 13 is completed. Similarly, the above removal steps are reversed to complete the installation of the first arc damping plate 12 and the second arc damping plate 13;

[0042] When the motor 23 drives the second bevel gear 24 to rotate in the opposite direction, the side of the slider 66 away from the inclined surface abuts against the inner wall of the third slide groove 67, so that the turntable 4 cannot rotate in the opposite direction, the first bevel gear 22 drives the fifth bevel gear 38 to rotate through the first rotating shaft 9, the fifth bevel gear 38 drives the first connecting shaft 35 and the fourth bevel gear 36 to rotate through the sixth bevel gear 39, and the fourth bevel gear 36 drives the second rotating shaft 30 and the fan blade 32 to rotate through the third bevel gear 34, and the fan blade 32 can draw the air outside the cabinet 1 into the cabinet 1 through the filter screen 8, and the fifth bevel gear 38 drives the first connecting shaft 35 and the fourth bevel gear 36 to rotate through the third bevel gear 34. The second connecting shaft 56 and the worm 55 are driven to rotate through the seventh bevel gear 57, and the worm 55 drives the third rotating shaft 40 to rotate through the worm wheel 53. The third rotating shaft 40 drives the protrusion 52 to slide on the bottom of the lifting ring 46 through the second mounting plate 51, and the lifting ring 46 and the third fixing frame 47 are supported by the protrusion 52. When the protrusion 52 slides into the first slide groove 50, the lifting ring 46 and the third fixing frame 47 descend, and the third fixing frame 47 slides relative to the third guide column 48 and the second fixing frame 41. The bottom of the magnet block 49 contacts the top of the iron block 44. When the protrusion 52 moves from the first slide groove 50, the lifting ring 46 and the third fixing frame 47 descend. When the first slide 50 slides out, the protrusion 52 pushes the lifting ring 46 and the third fixing frame 47 to move up to the initial height, and the magnet block 49 drives the iron block 44, the second guide column 42 and the movable ring 7 to move up through the magnetic force, and the second compression spring 45 is in a compressed state. The second compression spring 45 applies pressure to the movable ring 7. When the magnet block 49 moves up to the highest position, the second compression spring 45 pushes the movable ring 7, the second guide column 42 and the iron block 44 to move down, and the iron block 44 is no longer magnetically attracted to the magnet block 49. Finally, the movable ring 7 and the filter screen 8 are lowered to the initial height, and the iron block 44 and the support portion 4 3, the dust on the filter screen 8 is shaken off from the filter screen 8 due to inertia, and the dust falls into the collection box 58, and the dust is collected by the collection box 58 to prevent the dust from falling into the external environment again. When it is necessary to clean the dust collected in the collection box 58, the staff drives the movable plate 63 to move downward, and the tension spring 64 is in a tensioned state to make the limit column 62 disengage from the mounting block 61, thereby releasing the limitation on the position of the mounting block 61, and the staff drives the collection box 58 to move horizontally to make the mounting block 61 disengage from the second slide groove 60, and the collection box 58 can be removed.
