[0002] A computer case is a shell used to install and assemble the internal hardware components of a computer. It is usually made of metal or plastic and has the function of fixing and protecting the internal parts. The purpose of setting heat dissipation holes on the shell of the case is to enhance the heat dissipation effect, effectively discharge the heat generated inside, and maintain the stable operation of the computer hardware. These heat dissipation holes can improve air circulation through natural convection or by installing fans, reduce the temperature of the hardware, thereby extending the service life of the hardware and improving system performance and stability.

[0003] The heat dissipation holes on the side of the computer case are used not only for heat dissipation, but also to prevent dust from entering the case.

[0033] A horizontal cylinder 13 is fixedly provided at an oblique upper portion of the side of the rear panel 7, and a heat sink 27 is fixedly provided at one end of the outer side of the rear panel 7. A circular array of heat dissipation holes 28 are arranged on the side of the heat sink 27. The heat sink 27 has a certain thickness and is flush with the outer wall of the connecting fold 31 to prevent the connecting fold 31 from colliding with the recovery bucket 18 when it moves horizontally.

[0034] The inner cavity of one end of the horizontal tube 13 away from the heat dissipation plate 27 is rotatably connected to the mounting plate 14, a rectangular groove 15 is opened on the side of the mounting plate 14, and mounting holes are reserved at the four corners of the rectangular groove 15. A cooling fan 16 is fixed inside the rectangular groove 15 with bolts. The length and inner cavity diameter of the horizontal tube 13 need to be set appropriately so that when the cooling fan 16 rotates one hundred and eighty degrees, the mounting plate 14 does not collide with the side wall of the rear panel 7.

[0035] The cooling fan 16 is a common computer case accessory in the prior art. The cooling fan 16 frame and the bottom of the horizontal tube 13 are both provided with threading holes 17 for the wiring of the cooling fan 16's own motor to pass through, so as to prevent the cooling fan 16 from curling its power supply wiring when the mounting plate 14 rotates.

The quick rotation assembly includes a docking ring 11, a one-way bearing 10, a docking seat 9, and a release rod 8. The end of the cleaning screw 12 is sleeved with a one-way bearing 10. The other end of the cleaning screw 12 is threaded into the active gear rod 23. A threaded cavity is reserved on the side of the active gear rod 23. When the cleaning screw 12 rotates, the active gear rod 23 is forced to move horizontally, and the depth of the inner cavity of the top protection box 5 needs to be set appropriately. When the top protection box 5 is installed on the top of the flat board 1, the top of the active gear rod 23 fits with the top of the inner cavity of the top protection box 5.

[0038] A driven gear 141 is stably meshed on the side of the active gear rod 23, and the bottom of the driven gear 141 is concentrically fixed on the top of the mounting plate 14. A transverse rod 25 is fixedly arranged in the middle position of the side of the active gear rod 23, and a vertical folding rod 26 is fixedly arranged on the other end of the transverse rod 25. A recovery bucket 18 is fixedly arranged on the bottom of the other end of the vertical folding rod 26. The cross-sectional size of the recovery bucket 18 is not less than the diameter of the heat dissipation plate 27. A guide rod 24 is movably inserted into the side of the transverse rod 25, and both ends of the guide rod 24 are fixedly connected to the side of the inner cavity of the top protective box 5. The top protective box 5 is fixed to the top of the flat panel 1 through the mounting rod 4, and the guide rod 24 assists the transverse rod 25 to move horizontally.

[0039] A central tube 19 is fixedly provided at the center position of the side of the recovery bucket 18, and a temporary storage component for temporarily storing dust is provided at the end of the central tube 19. The temporary storage component includes a recovery tube 20, a filter hole 21, and a release block 22. The side of the recovery tube 20 is threaded into the outer wall of the central tube 19, and the filter holes 21 are arranged in a circular array on the side of the recovery tube 20. The inner cavity diameter of the recovery tube 20 is much larger than the inner diameter of the central tube 19, and the inner cavity at the end of the recovery tube 20 and the outer wall of the central tube 19 are both provided with threads.

[0040] Release blocks 22 are equidistantly arranged on the outer wall of the recovery barrel 20, a side protection box 6 is fixedly arranged on the side of the top protection box 5, an accommodating chamber 61 is opened on the side of the side protection box 6, and the longitudinal width of the accommodating chamber 61 is not less than the longitudinal width of the recovery bucket 18. The outer wall of the one-way bearing 10 is embedded in the inner ring wall of the docking ring 11, and a docking seat 9 is fixedly arranged on the top of the outer wall of the docking ring 11. The side wall of the docking seat 9 is rotatably connected with a release rod 8. Therefore, the presence of the one-way bearing 10 allows the user to continuously drive the cleaning screw 12 to rotate through the one-way bearing 10 by continuously swinging the release rod 8 in a narrow space.

[0041] The specific implementation steps and principles of the present invention are as follows:

[0042] When the whole device is working normally, the recycling bucket 18 is retracted into the accommodating chamber 61, and at this time, when the cooling fan 16 rotates, its wind direction is from the outer wall of the chassis to the inner cavity of the chassis, and the dust in the air is intercepted by the cooling holes 28 on the side of the cooling plate 27. When it is necessary to clean the dust intercepted on the outer side of multiple groups of cooling holes 28, the release rod 8 is manually rotated until the release rod 8 and the cleaning screw 12 are in a vertical state, and the release rod 8 is continuously and intermittently swung. Under the existence of the one-way bearing 10, the cleaning screw 12 drives the active gear rod 23 to move horizontally, and the active gear rod 23 drives the driven gear 141 to rotate. The driven gear 141 drives the cooling fan 16 on the mounting plate 14 to rotate one hundred and eighty degrees. At this time, the wind direction of the cooling fan 16 is from the inner cavity of the chassis to the outer wall of the chassis. During this period, the recovery bucket 18 is gradually moved out of the accommodating cavity 61 through the transverse rod 25 and the vertical folding rod 26, and finally wraps the multiple cooling holes 28. The dust intercepted by the multiple cooling holes 28 will enter the recovery cylinder 20 at the end of the recovery bucket 18 and be intercepted by the filter hole 21. When cleaning is completed, the recovery cylinder 20 is rotated out of the outer wall of the central tube 19 by human power through the release block 22 to dump the dust inside the recovery cylinder 20.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
