At the same time, more dust can easily enter the interior of mechanical equipment, causing damage to the equipment.

[0003] For example, a Chinese utility model patent (CN220531031U) discloses a dust prevention device for engineering construction, which records: "The dust at the bottom of the filter can be cleaned back and forth through the wind drive of the exhaust fan, so as to avoid the accumulation of the filter, increase the service life of the filter, and avoid the operator from frequently replacing it." It also records: "When the filter filters dust for a long time, a lot of dust will accumulate inside the filter holes and cause the filter to be blocked, which requires frequent manual disassembly and replacement, reducing the convenience of operation." Technical problems.

[0004] In summary, it can be seen that bolts are used to fix the filter in the prior art. However, this method has the following technical problems: during actual use of the device, the filter is fixed by bolts, and additional tools are needed to disassemble the filter during this process. The filter replacement process is relatively cumbersome, which reduces the efficiency of filter replacement.

[0029] As in the background art, during actual use of the device, the filter screen is fixed by bolts, and during this process, additional tools are needed to disassemble the filter screen. The filter screen replacement process is relatively troublesome, which reduces the filter screen replacement efficiency.

[0030] In order to solve this technical problem, the utility model provides a dustproof device, which is applied to the dustproof device for facilitating replacement of the filter screen.

[0031] Specifically, please refer to Figure 1-Figure 2 , the dust prevention device specifically includes:

[0032] The device comprises a housing 1, a replacement mechanism 5 is provided on the housing 1, a vibration mechanism 6 is provided on the housing 1, a vacuum cleaner 4 is fixedly mounted on the outer wall of the housing 1, an air outlet pipe of the vacuum cleaner 4 is fixedly connected to the inner wall of the housing 1, a support frame 2 is fixedly connected to the outer wall of the housing 1, and a dust box 3 is closely attached to the bottom of the housing 1;

[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0036] Embodiment 1:

[0037] Please refer to Figure 2-Figure 4 , a dust prevention device, comprising:

[0038] The disassembly assembly includes a movable door 9 movably connected to the inner wall of the device housing 1, and the movable door 9 is inserted into the corresponding hole groove on the device housing 1 to limit the position of the mounting frame 7 and the filter plate 8, thereby reducing the horizontal movement of the mounting frame 7 and the filter plate 8, so that the position of the second magnet 19 at the bottom of the mounting frame 7 corresponds to the position of the first magnet 18. The side of the movable door 9 away from the mounting frame 7 is fixedly connected with a fixed handle 14, and the side of the movable door 9 close to the mounting frame 7 and near the four corners are fixedly connected with buckles 10. The buckle 10 is combined with the block 12 to limit the movable door 9 to prevent the movable door 9 from detaching, thereby improving the stability of the device.

[0039] The limiting component includes a sliding plate 11 slidably connected to the inner wall of the device housing 1. The horizontal cross-section of the sliding plate 11 is larger than the horizontal cross-section of the block 12, which limits the downward movement of the block 12 and improves the stability of the device. The bottom of the sliding plate 11 is fixedly connected to the block 12 adapted to the buckle 10. The buckle 10 is provided with an inclined surface for squeezing the block 12. The bottom of the block 12 is provided with a chamfer. The top of the sliding plate 11 is fixedly connected to a limiting spring 13. The limiting spring 13 is always in a compressed state in the device, and the top of the limiting spring 13 is fixedly connected to the inner wall of the device housing 1.

[0040] Through the above structural design, the fixed handle 14 is pulled to drive the movable door 9 to move to the outside of the device housing 1, so that the buckle 10 squeezes the block 12, so that the block 12 and the sliding plate 11 slide along the inner wall of the device housing 1 to the inside of the device housing 1. In this process, the limiting spring 13 is further compressed. After the buckle 10 leaves the block 12, the limiting spring 13 releases the elastic force, so that the sliding plate 11 and the block 12 slide to a suitable position inside the device housing 1. At this time, after the movable door 9 is taken away from the device housing 1, the installation frame 7 and the filter plate 8 can be taken out from the inside of the device and replaced with new ones. After the new installation frame 7 and the filter plate 8 are placed, the movable door 9 is placed in the corresponding groove on the device housing 1 and squeezed.

[0041] Embodiment 2:

[0042] The dustproof device provided in Example 1 is further optimized, specifically, as follows Figure 5-Figure 6 As shown, the vibration mechanism 6 includes a drive motor 15, a rotating rod 16, a vibration assembly, and a clamping assembly. The outer wall of the device housing 1 is fixedly connected to the drive motor 15, and the output end of the drive motor 15 is fixedly connected to the rotating rod 16, which is rotatably connected to the inner wall of the device housing 1.

[0043] The vibration assembly includes second magnets 19 fixedly connected to the bottom of the two mounting frames 7, respectively; the outer wall of the rotating rod 16 and the fixing frames 17 located below the two second magnets 19 are respectively fixedly connected; the inner walls of the two fixing frames 17 are respectively fixedly connected with first magnets 18 adapted to the second magnets 19; the first magnets 18 and the second magnets 19 repel each other when in a horizontal state, to avoid attraction, which causes the mounting frame 7 to move downward to a certain distance, limits the rotation of the fixing frame 17, and improves the stability of the device.

[0044] The clamping assembly includes a fixed cylinder 20 respectively fixedly connected to the inner wall of the device housing 1, and the inner wall of the fixed cylinder 20 is slidably connected with a sliding column 21. The bottom of the sliding column 21 is provided with an inclined surface, which is adapted to the inclined surface provided on the mounting frame 7, so that during the process of replacing the mounting frame 7 and the filter plate 8, the mounting frame 7 and the filter plate 8 are pushed into the appropriate position inside the device housing 1, thereby improving the convenience of device installation. A blocking plate is provided at one end of the sliding column 21 located inside the fixed cylinder 20 to prevent the sliding column 21 from detaching from the fixed cylinder 20, thereby improving the stability of the device. A fixed spring 22 is fixedly connected to one end of the sliding column 21 located inside the fixed cylinder 20, and the end of the fixing spring 22 away from the sliding column 21 is fixedly connected to the inner wall of the fixed cylinder 20.

[0045] Through the above structural design, the drive motor 15 is started to drive the rotating rod 16 to rotate, and then drive the fixed frame 17 and the first magnet 18 to move. The movement of the first magnet 18 makes the mounting frame 7 and the filter plate 8 vibrate up and down under the restriction of the fixed cylinder 20, the sliding column 21 and the fixed spring 22, so that the dust inside the filter plate 8 can be shaken off. In this process, the sliding column 21 slides inside the fixed cylinder 20, and the fixed spring 22 is deformed with the movement of the sliding column 21.
