[0034] Reference Figure 1 - Figure 2 The utility model provides an embodiment: an automatic cleaning device for dust accumulation in the filter screen of a ventilation duct in a machine room, comprising a duct body 1, a filter plate 2 is arranged inside the duct body 1, and the inner wall material of the front and rear ends of the duct body 1 is set to soft rubber. Through the setting of the material, it is ensured that when the filter plate 2 is turned over, there is a squeezed space on the inner wall of the duct body 1, and it can be ensured that it fits with the edge of the filter plate 2 during use, and a dust filter 3 is fixedly connected to the middle of the filter plate 2.

[0035] Reference Figure 2 , Figure 4 and Figure 6 A cleaning mechanism 4 is provided inside the pipe body 1. The cleaning mechanism 4 includes a mounting groove 41. The mounting groove 41 is formed by merging a rectangular parallelepiped with a longer height at the rear end and a rectangular parallelepiped groove with a shorter length at the front end. The mounting groove 41 is opened inside the pipe body 1. A reciprocating screw rod 42 is rotatably connected to the inner wall of the mounting groove 41. One end of the reciprocating screw rod 42 passes through the inner wall of the pipe body 1. A motor 410 is fixedly connected to the outer wall of the pipe body 1. The output shaft of the motor 410 is fixedly connected to the reciprocating screw rod 42.

[0036] Reference Figure 4 - Figure 6 A slider 43 is provided on the outer wall of the reciprocating screw rod 42, and the rear end of the slider 43 is slidably connected to the inner wall of the mounting groove 41, and a brush 44 is fixedly connected to the left side of the front end of the slider 43, and the bristles of the brush 44 are arranged on the top. A fixing component 45 is provided below the filter plate 2, and the fixing component 45 includes a sleeve 451, and the top end of the sleeve 451 is fixedly connected to the bottom end of the filter plate 2, and a block 452 is slidably connected to the inner wall of the sleeve 451. The cross-sectional shape of the block 452 is a trapezoid, and the top length of the block 452 is longer than the bottom length. The left end of the block 452 is elastically connected to the inner wall of the sleeve 451 through a spring 453, and one end of the spring 453 is fixedly connected to the left end of the block 452, and the other end of the spring 453 is fixedly connected to the inner wall of the sleeve 451.

[0037] Reference Figure 4 - Figure 6The fixing assembly 45 also includes a mounting block 454, which is fixedly connected to the inner wall of the pipe body 1 below the filter plate 2. A switch 46 is arranged at the top of the mounting block 454, a groove is arranged in the middle of the mounting block 454, and a sliding groove 455 is arranged on the inner wall of the pipe body 1. The distance between the bottom end of the sliding groove 455 and the top end of the groove in the middle of the mounting block 454 is slightly greater than the height of the block 452. A baffle 456 is slidably connected to the inner wall of the sliding groove 455, and the baffle 456 is concave in shape.

[0038] Reference Figure 4 - Figure 6 The front end of the blocking bar 456 is at the same horizontal position as the recessed position in the middle of the mounting block 454. By setting the same horizontal position, it is ensured that when the block 452 moves to the recessed position, the blocking bar 456 can block the block 452, so that the filter plate 2 cannot be reset before the brush 44 is reset. The right end of the blocking bar 456 is elastically connected to the inner wall of the sliding groove 455 by a spring 457, one end of the spring 457 is fixedly connected to the right end of the blocking bar 456, and the other end of the spring 457 is fixedly connected to the inner wall of the sliding groove 455.

[0039] Reference Figure 2 , Figure 3 and Figure 7 A flip assembly 6 is provided at the left end of the filter plate 2, and the flip assembly 6 includes a rotating shaft 61. The right end of the rotating shaft 61 is fixedly connected to the left end of the filter plate 2. An assembly groove 62 is provided on the inner wall of the left end of the pipe body 1. The shape of the assembly groove 62 is a combination of a straight notch with a larger diameter on the left side, a straight notch with a smaller diameter on the right end, and a rectangular groove at the rear end. A gear 63 is fixedly connected to the left end of the rotating shaft 61, and a mounting plate 64 is fixedly connected to the inner wall of the assembly groove 62. The front end of the mounting plate 64 is rotatably connected with teeth 65, which mesh with the teeth on the outside of the gear 63. The number of teeth 65 is half the number of teeth of the gear 63. The proportional relationship between the teeth 65 and the number of teeth of the gear 63 ensures that the filter plate 2 can rotate 180 degrees each time it moves upward. The rotation connection point between the teeth 65 and the mounting plate 64 is set below the rear end of the teeth 65.

[0040] Reference Figure 2 , Figure 3 and Figure 7 The front end of the mounting plate 64 is elastically connected to the lower end of the tooth 65 through a spring sheet 67, one end of the spring sheet 67 is fixedly connected to the front end of the mounting plate 64, and the other end of the spring sheet 67 is fixedly connected to the lower end of the tooth 65. The outer wall of the rotating shaft 61 is rotatably connected with a fixing ring 68, and the fixing ring 68 is slidably connected to the inner wall of the assembly groove 62. The bottom end of the fixing ring 68 is elastically connected to the inner wall of the assembly groove 62 through a spring three 69, one end of the spring three 69 is fixedly connected to the bottom end of the fixing ring 68, and the other end of the spring three 69 is fixedly connected to the inner wall of the assembly groove 62.

[0041] Working principle: When in use, when a lot of dust accumulates on the dust filter 3, due to the weight of the dust, the total gravity of the filter plate 2 and the dust filter 3 increases, so the filter plate 2 can move downward under the action of gravity.

[0042] When the filter plate 2 moves downward until the lower surface contacts the upper surface of the mounting block 454, the switch 46 is pressed, so the motor 410 starts and drives the reciprocating screw 42 to rotate, so that the slider 43 moves from right to left and then from left to right under the drive of the reciprocating screw 42, thereby driving the brush 44 to clean the dust filter 3 during the back and forth movement.

[0043] During the cleaning process, since the slider 43 moves to the left under the drive of the reciprocating screw rod 42, the baffle bar 456 moves to the left under the drive of the spring 2 457. Therefore, the front end left side of the baffle bar 456 is at the top of the block 452. Therefore, the block 452 is blocked by the baffle bar 456 and cannot move upward. Therefore, there is no situation where the filter plate 2 moves upward after the brush 44 cleans the dust on the right side, resulting in incomplete cleaning.

[0044] When the slider 43 moves to the right end, it pushes the blocking bar 456 to move rightward. At this time, the top of the block 452 is not blocked, so the spring three 69 drives the fixing ring 68 to move upward under the action of the rebound force, thereby causing the rotating shaft 61 to move upward, thereby driving the filter plate 2 to move upward.

[0045] During the upward movement of the filter plate 2, when the gear 63 contacts the teeth 65, the gear 63 cannot move upward directly because it is blocked by the teeth 65 and can only rotate under the drive of the teeth 65. Therefore, during the upward movement, the filter plate 2 can rotate 180 degrees.

[0046] When the filter plate 2 moves downward, since the teeth 65 can rotate downward, when the gear 63 contacts the teeth 65, the teeth 65 can be pushed to rotate downward. Therefore, the teeth 65 cannot block the gear 63 at this time, so the filter plate 2 will not rotate during the downward movement.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
