[0030] It should be noted that when the device is running, the servo motor 6 drives the first fan blade 7 to rotate, and introduces external air into the wind tube 1. In this process, some dust and impurities will be sucked in and attached to the outside of the rear wind cover 915. When the airflow passes through the second fan blade 913, it will drive the second fan blade 913 to rotate. Under the fixation of the second fixing frame 911, the second fan blade 913 can drive the cleaning brush 914 to rotate through the rotating shaft 912, and then the soft brush arranged on the rear side of the cleaning brush 914 can brush off the dust and impurities attached to the surface of the rear wind cover 915, so as to avoid blockage of the rear wind cover 915 and reduce the suction of external dust, so that the inhaled air is cleaner.

The threaded sleeve 415 threadedly connected to its surface moves backward along the thread line on the surface of the screw rod 414, thereby driving the connecting rod 416 to rotate, so that the sliding block 411 rotatably connected to it extends outward, driving the arc fixing plate 412 to fit the inner wall of the wall hole. The arrangement of the sliding rod 413 inside the arc fixing plate 412 further reinforces the arc fixing plate 412 to prevent the arc fixing plate 412 from tilting. When the arc fixing plate 412 is completely fitted into the inner wall of the hole, the entire device is fixed in the wall hole. The above steps can realize the rapid installation of the device, and it can also be quickly dismantled later, which is convenient for the later maintenance and cleaning of the device. After the device is installed, the servo motor 6 is started to drive the first fan blade 7 to rotate, so as to introduce external air into the air duct 1. In this process, The front wind cover 3 and the rear wind cover 915 arranged on the front and rear sides of the wind tube 1 can prevent foreign objects from entering the wind tube 1 to avoid damage to the device. However, some dust and impurities will be sucked in and attached to the outside of the rear wind cover 915. When the airflow passes through the second fan blade 913, it will drive the second fan blade 913 to rotate. Under the fixation of the second fixing frame 911, the second fan blade 913 can drive the cleaning brush 914 to rotate through the rotating shaft 912, and then the soft brush arranged on the rear side of the cleaning brush 914 can brush off the dust and impurities attached to the surface of the rear wind cover 915 to avoid clogging of the rear wind cover 915 and reduce the suction of external dust, making the inhaled air cleaner. During subsequent dismantling, the device can be fixed and removed by rotating the knob at the front end of the screw rod 414 counterclockwise.

[0032] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model.
