[0032] See also Figure 4 A plurality of air inlets 13 are provided through the upper end of the upper cover 8, a second thread 14 is provided inside the upper cover 8, the air inlet 13 is provided for inhaling air with dust, a plurality of anti-slip grooves 15 are provided outside the upper cover 8, the slide grooves are provided for facilitating the rotation of the upper cover 8, an outer tube 16 and an inner tube 17 are fixedly connected to the upper end of the upper cover 8, a baffle 18 is fixedly connected to the upper end of the outer tube 16 and the inner tube 17, the outer tube 16 and the inner tube 17 are provided for passing the air with dust,

[0033] See also Figure 1 , Figure 2 and Figure 3 A support frame 19 is fixedly connected to the inside of the shell 1, and a fan 20 is fixedly connected to the inside of the support frame 19. A plurality of air outlets 21 are opened through the bottom end of the outer wall of the shell 1. The fan 20 is provided to provide suction, and the filtered air is discharged from the air outlet 21. The rotating shaft 10 is rotatably arranged inside the collecting barrel 5. The cleaning brush 12 installed on the rotating shaft 10 can automatically clean the inside of the collecting barrel 5 during operation, effectively preventing dust from accumulating in the barrel and improving the efficiency of dust absorption. The collecting barrel 5 is slidably arranged inside the mounting tube 2, and a handle 7 is rotatably connected to the upper end of the outer wall of the collecting barrel 5. The handle 7 is provided to facilitate the collection barrel 5 to be pulled out of the mounting tube 2. The first thread 3 is threadedly connected to the second thread 14, and the first thread 3 is threadedly connected to the second thread 14 for threading the upper cover 8 to the upper end of the mounting tube 2.

[0034] In this embodiment, the dust absorption device is provided with a motor 9, a rotating shaft 10, a bracket 11 and a cleaning brush 12. When collecting dust, the motor 9 drives the rotating shaft 10 to rotate, and the rotating shaft 10 further drives the bracket 11 to rotate. The cleaning brush 12 fixed on one side of the bracket 11 rubs the inner wall of the collection barrel 5 and then scrapes off the dust adsorbed inside the collection barrel 5 due to the suction force, continuously cleaning the inside of the collection barrel 5, effectively preventing dust from accumulating in the barrel, and improving the efficiency of dust absorption.

[0035] It should be noted that after the collecting barrel 5 enters the mounting tube 2 , the retaining ring 6 on the outer wall of the collecting barrel 5 is blocked by the fixing ring 4 on the inner wall of the mounting tube 2 , thereby allowing the collecting barrel 5 to be placed inside the mounting tube 2 .

[0036] The working principle of the above embodiment is:

[0037] First, start the fan 20. The fan 20 is located inside the housing 1 and fixed by the support frame 19. The rotation of the fan 20 generates suction, so that the dusty air outside is sucked into the device. The dusty air enters the device through the air inlet 13 on the upper cover 8. The upper cover 8 is threadedly connected to the first thread 3 at the upper end of the mounting tube 2 through the second thread 14 to ensure the sealing of the device. When the air enters the device, the dust is captured by the collection barrel 5. The collection barrel 5 is slidably arranged inside the mounting tube 2 and is positioned by the retaining ring 6 and the fixing ring 4 to ensure that it is in the correct position. Due to the suction generated by the fan 20, the dust in the air is adsorbed on the inner wall of the collection barrel 5. Driven by the motor 9, the rotating shaft 10 starts to rotate. The bracket 11 and the cleaning brush 12 on the rotating shaft 10 also rotate accordingly. The cleaning brush 12 rubs the inner wall of the collection barrel 5 to scrape off the dust adsorbed thereon. In this way, the inner wall of the collection barrel 5 is always kept clean, preventing dust accumulation and improving the efficiency of dust absorption. The air after dust collection is discharged through the air outlet 21 at the bottom of the shell 1. When the dust in the collection barrel 5 accumulates to a certain extent, the user can draw it out of the mounting tube 2 by turning the handle 7.
