The convex-shaped structure can not only provide good guidance, but also enhance the strength and rigidity of the structure to a certain extent, ensuring that it can maintain a good working condition during long-term use, especially when it is impacted by airflow during ventilation, and reduce failures or performance degradation caused by problems such as structural deformation.

[0029] refer to Figure 1-Figure 2 Annular grooves 11 are provided at equal intervals on the outside of the ventilation pipe 1, and a mounting frame 12 is fitted and connected to the inner side of the annular groove 11. Mounting holes 10 are also provided on both sides of the outer end of the mounting frame 12. The annular grooves 11 provided at equal intervals provide an accurate installation position for the mounting frame 12, ensuring that the mounting frame 12 is evenly distributed, so that the ventilation pipe 1 is subjected to more uniform and stable force during installation and fixation. The fitting connection between the annular grooves 11 and the inner side of the mounting frame 12 increases the contact area and improves the firmness of the connection. The mounting holes 10 provided on both sides of the outer end of the mounting frame 12 provide an interface for the fixed installation of the ventilation pipe 1 and other structures or equipment, which is convenient for fastening by bolts and other connecting parts, so as to realize the stable installation and reliable operation of the ventilation pipe 1 in specific scenarios. This design not only takes into account the fixing needs of the ventilation pipe 1 itself, but also facilitates its connection and integration with the surrounding environment.

[0030] refer to Figure 3-Figure 4The cleaning mechanism 7 includes an inner rail 71, which is fixedly installed in the middle of the filter box 5. The inner rail 71 and the dust filter 64 are arranged at an angle. The inner rail 71 is rotatably connected with a screw rod 72. The bottom of the inner rail 71 is fixedly connected with a drive motor 73. The output end of the drive motor 73 is fixedly connected to the bottom of the screw rod 72. The outer surface of the screw rod 72 is threadedly connected with a slider 74. The side of the slider 74 close to the dust filter 64 is fixedly connected with a brush plate 75. The top of the brush plate 75 is fitted with the bottom of the dust filter 64. The drive motor 73 drives the screw rod 72 to rotate, and the slider 74 can move linearly along the inner rail 71 through the threaded connection. The brush plate 75 fixedly connected to the slider 74 can brush and clean the bottom of the dust filter 64 as the slider 74 moves, effectively preventing dust accumulation from clogging the filter. The design of this cleaning mechanism 7 is ingenious and practical, and can automatically clean and maintain the dust filter 64, ensuring a continuous good filtering effect. At the same time, there is no need for frequent manual cleaning, which improves the degree of automation and ease of use of the equipment.

[0031] refer to Figure 1-Figure 2 A connecting pipe 4 is fixedly installed at the output end of the fan 2, and a mounting flange 9 is also fixedly installed at the outer end of the connecting pipe 4. The setting of the mounting flange 9 on the connecting pipe 4 at the output end of the fan 2 is mainly to facilitate the connection with other ventilation pipes 1 or equipment, making the connection between different parts more convenient, firm and reliable. By installing the flange 9, it is possible to quickly achieve docking and integration with other systems, thereby improving the installation efficiency and operation stability of the entire ventilation system.

[0032] Principle and advantages of use: By setting the filtering mechanism 6, during the use of the device, by starting the fan 2 to run, the fan 2 can absorb air through the ventilation pipe 1 and the connecting pipe 8, and the air is discharged through the connecting pipe 4 at the output end of the fan 2. During the air circulation process inside the filter box 5, the dust in the air can be assisted by the dust filter 64. Since the dust filter 64 is tilted, on the one hand, the dust filter 64 is located inside the filter box 5 with a larger filtering area, which can improve the efficiency of filtering ventilation, and the dust filtered out during the filtering process can adaptively fall into the inside of the guide bucket 62. When it is necessary to clean the dust, just loosen the hand-tightening screw to remove the sealing cover 68 from the bottom of the guide bucket 62, so that the whole device is easy to quickly clean the dust inside the guide bucket 62, so that the whole device has a strong dustproof function and is easy to quickly clean the dust;

[0033] By setting the filtering mechanism 6, the device can be operated by starting the driving motor 73 during use, and the driving motor 73 is used to drive the screw rod 72 to rotate. The rotation of the screw rod 72 can drive the slider 74 located inside the inner rail 71 to slide. The slider 74 slides linearly inside the inner rail 71, which can assist in driving the brush plate 75 to move up and down. The brush plate 75 slides up and down and the brush plate 75 and the bottom of the dust filter 64 are connected in a close connection. At this time, the brush plate 75 can be heard to brush the bottom of the dust filter 64. Cleaning by rubbing can prevent the outer surface of the dust filter 64 from being clogged by dust, so that the whole device can have a strong dust-proof performance, and can prevent dust from clogging the outer surface of the dust filter 64. When the dust filter 64 needs to be maintained and repaired, the hand-tightened bolt 67 can be twisted, and the mounting plate 66 can be removed at this time. When the mounting plate 66 loses its limit, the sealing plate 65 can be pulled out from the front of the filter box 5, and the dust filter 64 can be removed from the inside of the filter box 5, which can improve the convenience of overall disassembly and maintenance of the device.
