DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides: a ventilation filter cleaning device, such as Figure 1-Figure 5As shown, it includes a connecting frame 1, a filter screen 2 is arranged inside the connecting frame 1, and slide grooves 3 are opened on both sides of the top of the filter screen 2, and the rear side of the inner wall of one group of slide grooves 3 is rotatably connected with a first screw rod 4 through a bearing, the front end of the first screw rod 4 penetrates to the front side of the connecting frame 1 and is fixedly connected to a first motor 5, and a connecting plate 6 is fixedly connected to the right side of the first motor 5, and the back of the connecting plate 6 is fixedly connected to the front side of the connecting frame 1, and a slider 7 is arranged inside each group of slide grooves 3, and one group of sliders 7 is threadedly connected to the first screw rod 4, a U-shaped sleeve 8 is arranged on the top of the filter screen 2, and the two sides of the U-shaped sleeve 8 are fixedly connected to the inner side of the slider 7, and the left side of the inner wall of the U-shaped sleeve 8 is rotatably connected with a second screw rod 9 through a bearing, and a screw block 10 is threadedly connected to the surface of the second screw rod 9, and a cleaning brush 11 is fixedly connected to the bottom of the screw block 10, and the right end of the second screw rod 9 penetrates to the right side of the connecting frame 1 and is fixedly connected to a second motor 12, and a connecting block 13 is fixedly connected to the bottom of the second motor 12, and the left side of the connecting block 13 is fixedly connected to the right side of the connecting frame 1.

[0023] In this embodiment, through the arrangement of the first motor 5, the second motor 12 and the cleaning brush 11, when the filter 2 needs to be cleaned, the first motor 5 can be started, and the output shaft of the first motor 5 drives the slider 7, the U-shaped sleeve 8 and the cleaning brush 11 to move to the front side, so that the dust on the top of the filter 2 can be cleaned. When the cleaning brush 11 moves to the front side of the filter 2, the second motor 12 can be started, and the rotation of the second motor 12 drives the second screw 9 to rotate, and the rotation of the second screw 9 drives the screw block 10 and the cleaning brush 11 to move to the right. When the cleaning brush 11 moves to a suitable distance, the second motor 12 can be turned off, and finally the first motor 5 can be reversed to allow the cleaning brush 11 to continue to move to the rear side, so that the cleaning brush 11 can move back and forth to sweep the dust on the top of the filter 2.

[0024] Preferably, another group of slide grooves 3 are internally fixedly connected with a limiting rod 14, the front end of the limiting rod 14 penetrates to the front side of another group of sliders 7, the limiting rod 14 and the other group of sliders 7 are slidably connected, and the U-shaped sleeve 8 is laterally fixedly connected with a fixing rod 15 inside, and the right end of the fixing rod 15 penetrates to the right side of the screw block 10 and is slidably connected to the screw block 10.

[0025] By setting the limiting rod 14 and the fixing rod 15, the limiting rod 14 can limit the slider 7 to prevent the first screw rod 4 from affecting the movement of another group of sliders 7 when rotating, and the fixing rod 15 prevents the second screw rod 9 from driving the screw block 10 to rotate when rotating, which will cause the cleaning brush 11 to be unable to effectively clean the filter 2.

[0026] Among them, the four corners of the bottom of the filter screen 2 are fixedly connected with a fixed block 16, the top of the fixed block 16 contacts the bottom of the connecting frame 1, the inner side of the fixed block 16 is fixedly connected with a placement plate 17, the outer side of the placement plate 17 is slidably connected with a fixed plate 18, the top of the placement plate 17 contacts the bottom of the fixed plate 18, the outer side of the fixed plate 18 contacts the inner side of the placement plate 17, a fixing groove 22 is opened at the bottom of the fixed plate 18, the top of the fixed plate 18 contacts the inner wall of the fixing groove 22, the bottom of the fixed plate 18 is fixedly connected with a limiting block 23, and the inner side of the limiting block 23 contacts the outer side of the placement plate 17.

[0027] In this embodiment, by setting the fixing block 16 and the fixing plate 18, when the fixing plate 18 is pushed outward, the top of the fixing plate 18 will contact the bottom of the fixing block 16. At this time, the fixing block 16 can be limited, thereby preventing the filter screen 2 from becoming unstable inside the connecting frame 1, thereby causing the connecting frame 1 and the filter screen 2 to separate.

[0028] It is worth mentioning that a connecting rod 19 is fixedly connected to the inner side of the fixed plate 18, and a rectangular block 20 is fixedly connected to the inner side of the placing plate 17. The inner end of the connecting rod 19 passes through the inner side of the rectangular block 20 and is slidably connected to the rectangular block 20. A tension spring 21 is sleeved on the surface of the connecting rod 19, and the inner end of the tension spring 21 is fixedly connected to the outer side of the rectangular block 20, and the outer end of the tension spring 21 is fixedly connected to the inner side of the fixed plate 18.

[0029] By setting the tension spring 21 and the connecting rod 19, the connecting rod 19 and the fixing plate 18 can always bear the tension of the tension spring 21, so that the fixing plate 18 can limit the fixing block 16 more stably, thereby preventing the filter 2 from shaking.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
