[0021] When in use, first pull the dust suction head 5 to extend the telescopic tube 4, then twist the telescopic tube 4 according to the position to be cleaned, so as to adjust the angle of the dust suction head 5, then turn on the power to start the suction fan 7 to suck the outer wall air together with the dust from the dust suction head 5 into the interior of the housing 1, and when the suction fan 7 works again, it will drive the dust removal mechanism to work through the connecting shaft 10, so that the dust removal mechanism cleans the dust adhering to the computer hardware, and cooperates with the suction force generated by the suction fan 7 to pass the dust together with the air through the gaps between the multiple groups of guide plates 8 on the surface of the connecting plate 9 into the interior of the housing 1, and the dust collecting component inside the housing 1 can collect the dust, so that the sucked dust enters the interior of the dust collecting bin 34 through the annular baffle 2, and the air enters the suction sleeve 3 and is discharged after being filtered by the dustproof net 45. After use, push the dust suction head 5 to shrink the telescopic tube 4, so that the dust suction head 5 is reconnected to the housing 1 and squeezes the rubber ring 6.

[0023] During use, when the telescopic tube 4 is extended, the support frame 12 limits the silicone connecting rod 11, so that the dust collector head 5 will pull the silicone connecting rod 11 through the support frame 12 to slide out of the interior of the connecting shaft 10. When the suction fan 7 is working, it will drive the silicone connecting rod 11 to rotate on the surface of the support frame 12 through the connecting shaft 10.

When the transmission disk 18 rotates, it drives the transmission gear 20 to rotate inside the connecting plate 9 through the transmission rod 17, and through the engagement between the transmission gear 20 and the toothed belt 21, it drives the toothed belt 21 to rotate on the surface of the connecting plate 9. The multiple sets of auxiliary gears 22 arranged inside the connecting plate 9 play an auxiliary role in the rotation process of the toothed belt 21. When the toothed belt 21 rotates, it can drive the brush 23 to clean the surface of the computer hardware, thereby removing the dust adhering to the surface of the computer, and the cleaned dust will pass through the gaps between the multiple sets of guide plates 8 into the interior of the housing 1.

[0024] See also Figure 5The crushing structure includes a connecting block 24 installed on the inner wall of the shell 1 and rotatably connected to the connecting shaft 10, a connecting ring 25 is rotatably connected to the outer wall of the connecting block 24, a first blade 26 is fixedly connected to the outer wall of the connecting ring 25, a conical block 27 is fixedly connected to the outer wall of the connecting shaft 10, a second blade 28 is fixedly connected to the outer wall of the conical block 27, an outer toothed ring 29 is fixedly connected to the outer wall of the conical block 27, a connecting gear 30 adapted to the outer toothed ring 29 is provided on the outer wall of the connecting block 24, and an inner toothed ring 31 adapted to the connecting gear 30 is provided on the inner wall of the connecting ring 25.

[0025] When in use, the dust entering the interior of the housing 1 will diffuse around along the inclined surface of the conical block 27 through the inclined surface of the conical block 27, and the connecting shaft 10 will drive the second blade 28 and the outer gear ring 29 to rotate synchronously through the conical block 27 when rotating, and the outer gear ring 29 will drive the connecting gear 30 to rotate on the surface of the connecting block 24 through the meshing of the outer gear ring 29 and the connecting gear 30, and when the connecting gear 30 rotates, the meshing of the inner gear ring 31 will drive the connecting ring 25 to rotate on the surface of the connecting block 24 in the opposite direction of the conical block 27 through the inner gear ring 31, and the connecting ring 25 will drive the first blade 26 to rotate synchronously when rotating, and cooperate with the second blade 28 to crush large particles of dust or hair entering the interior of the housing 1.

[0026] See also Figure 2 , Figure 6 and Figure 7 The dust collecting assembly includes a dust cover 32 installed on the outer wall of one end of the suction sleeve 3, a first scraper 33 adapted to the dust cover 32 is arranged on the outer wall of the connecting shaft 10, a dust inlet 35 is opened on the outer wall of the annular baffle 2, a slide groove 36 is opened on the inner wall of the annular baffle 2, a sealing plate 37 adapted to the dust inlet 35 is arranged on the inner wall of the slide groove 36, a spring 38 adapted to the sealing plate 37 is arranged on the inner wall of the slide groove 36, a spring sheet 39 is fixedly connected to the outer wall of the sealing plate 37, a ball 40 is rotatably connected to the outer wall of one end of the spring sheet 39, an extrusion groove 41 adapted to the spring sheet 39 is arranged on the inner wall of one end of the slide groove 36, air inlets 42 are opened at equal intervals on the outer wall of the suction sleeve 3, an auxiliary suction pipe 43 adapted to the air inlet 42 is arranged on the inner wall of the suction sleeve 3, and a filter screen 44 is installed on the inner wall of the air inlet 42.

[0027] When in use, the air and dust entering the shell 1 are filtered by the dust cover 32, and then the air passes through the dust cover 32 into the interior of the suction sleeve 3 and is discharged, while the dust is scraped onto the surface of the annular baffle 2 by the first scraper 33, and then the connecting shaft 10 continues to drive the first scraper 33 to rotate, so that the first scraper 33 scrapes the dust on the surface of the annular baffle 2 into the interior of the dust inlet 35, and as the first scraper 33 continues to rotate, one end of the first scraper 33 rotates to squeeze the surface of the spring sheet 39, thereby pushing the blocking plate 37 to slide into the interior of the slide groove 36 and squeeze the spring 38, thereby releasing the limit on the dust inlet 35, and at this time, the suction force of the suction fan 7 on the auxiliary suction pipe 43 makes the dust The dust will be sucked into the dust collecting bin 34 together with the air, and will be filtered by the filter screen 44 to trap the dust in the dust collecting bin 34, while the air will pass through the air inlet 42 and the auxiliary air suction pipe 43 into the interior of the air suction sleeve 3 and be discharged. During the sliding process of the blocking plate 37 into the slide groove 36, the extrusion groove 41 will exert a pressure on the surface of the spring sheet 39, so that the raised end of the spring sheet 39 moves toward the surface of the blocking plate 37 and separates from the first scraper 33. At this time, the force of the spring 38 pushes the blocking plate 37 to reset and re-limit the dust inlet 35, and the ball 40 on the surface of the raised end of the spring sheet 39 can reduce the friction between the spring sheet 39 and the first scraper 33.

[0028] See also Figure 8 The dust collecting assembly also includes a blocking cover 46 for blocking the opening at one end of the dust collecting bin 34 . The blocking cover 46 is threadedly connected to the suction sleeve 3 . A second scraper 47 adapted to the dust collecting bin 34 is provided on the outer wall of the suction sleeve 3 .

[0029] During use, after cleaning is completed, the blocking cover 46 is rotated to separate the blocking cover 46 from the suction sleeve 3. During this process, the blocking cover 46 will drive the second scraper 47 to rotate inside the dust collecting bin 34. Since the second scraper 47 is designed to be arc-shaped, the second scraper 47 can collect the dust inside the dust collecting bin 34 toward the blocking cover 46 when rotating. Then, when the blocking cover 46 is pulled outward to pull the second scraper 47 out of the dust collecting bin 34, the dust can be taken out of the dust collecting bin 34 together.
