Description

Technical Field

[0001] This invention relates to the technical field of computer cases, and more specifically to a self-maintaining computer case. Background Technology

[0002] As the core component supporting and protecting computer hardware, the computer case's heat dissipation performance directly determines the operational stability and lifespan of core hardware such as the CPU and graphics card. To prevent external dust from entering the case and clogging the airflow, thus affecting the hardware's cooling efficiency, most modern computer cases have filters at the air vents. These filters block dust from entering, ensuring unobstructed airflow within the case. However, over time, dust, lint, and other impurities will gradually accumulate on the surface of the filter. If not cleaned in time, the ventilation area of ​​the heat dissipation vent will be reduced, and the hot air inside the chassis will not be effectively discharged, which will lead to hardware temperature rise, running lag, crashes and other malfunctions. In severe cases, it may even cause hardware to burn out. Currently, there are two methods for cleaning chassis filters. One method relies on manual maintenance, which requires frequent disassembly of the chassis side panel, removal of the filter for cleaning, and reassembly of the chassis after cleaning. The whole process is time-consuming and labor-intensive. The other method uses an automatic cleaning mechanism inside the chassis, such as a fixed cleaning brush or a simple dust collection device. However, there are still shortcomings: First, the cleaning brush is mostly fixed in a single position and cannot cover the full height of the filter, resulting in prominent local dust accumulation problems. Second, during the cleaning process, dust easily adheres to the surface of the dust collection components, causing secondary pollution. Summary of the Invention The purpose of this invention is to provide a self-maintaining computer chassis to overcome the above-mentioned defects in the prior art.

[0003] A self-maintaining computer chassis includes a chassis body, a lifting mechanism, and a cleaning mechanism. The lifting mechanism is located inside the chassis and is used to drive the cleaning mechanism on it to move within the chassis. The cleaning mechanism is used to clean the filter screen on the chassis body.

[0004] Preferably, the lifting mechanism includes a bracket, a drive screw, and a drive motor. The bracket is located on the top wall of the chassis body. The two ends of the drive screw are rotatably connected to the bracket and the bottom wall of the chassis body, respectively. The drive motor is mounted on the side of the bracket and has a bevel gear on its output shaft. The bevel gear meshes with a bevel gear on the upper end of the drive screw.

[0005] Preferably, the cleaning mechanism includes a fixed frame, a dust receiving plate, a cleaning brush, a dust pump, and a dust collection tank. Movable blocks are bolted to both sides of the fixed frame. One movable block on one side of the fixed frame is screwed to a drive screw via a screw nut. The other movable block on the fixed frame is slidably connected to a slide rod inside the chassis. The dust receiving plate is made of elastic material and is located within the fixed frame. A dust inlet is provided between the upper surface of the dust receiving plate and the fixed frame. A toggle plate is provided on the front side of the dust receiving plate. The cleaning brush is located on the front side of the dust receiving plate and abuts against the filter screen on the chassis. The dust pump is located on the top of the fixed frame. The dust inlet of the dust pump is connected to an air collection box bolted to the top of the fixed frame via a dust suction pipe. The air collection box is connected to a dust inlet on the top of the fixed frame. The dust outlet of the dust pump is connected to the dust collection tank on the top of the fixed frame via a dust discharge pipe.

[0006] Preferably, the fixing frame has an "L" shaped structure.

[0007] Preferably, the ash receiving plate has an overall arc-shaped structure.

[0008] Preferably, there are two actuating plates symmetrically arranged at both ends of the ash receiving plate.

[0009] Preferably, the dust inlet holes are provided in a plurality of form and are evenly distributed along the top of the fixing frame.

[0010] Preferably, the ash collection tank is threadedly connected to the fixing seat on the top of the fixing frame, and the top of the ash collection tank is threadedly connected to a tank cover, which is provided with an exhaust filter screen.

[0011] Preferably, the bracket has an "L" shaped structure.

[0012] The beneficial effects achieved by this invention are as follows: This application uses a lifting mechanism to drive the cleaning mechanism to move smoothly along the height of the filter screen. The cleaning brush moves synchronously with the fixed frame and comes into contact with the filter screen, achieving full-surface cleaning of the filter screen without dead corners. The design of the elastic arc-shaped dust receiving plate and the actuating plate, when the actuating plate moves with the fixed frame, is driven by the filter holes on the filter screen to bend and vibrate the dust receiving plate, which not only shakes off the dust remaining on the dust receiving plate, but also scrapes off some of the dust remaining on the inner wall of the machine box by bending the dust receiving plate, reducing the adhesion of contaminants. The dust pump forms a uniform negative pressure through the air collection box and dust inlet, which efficiently sucks the cleaned dust into the dust collection tank, preventing the dust from spreading into the machine box.

[0024] like Figure 1-7 As shown, the present invention provides a self-maintaining computer chassis, including chassis body 1, lifting mechanism 2 and cleaning mechanism 3; Furthermore, the lifting mechanism 2 is located inside the chassis body 1 and is used to drive the cleaning mechanism 3 on it to move within the chassis body 1. The lifting mechanism 2 includes a bracket 21, a drive screw 22, and a drive motor 23. The bracket 21 has an "L"-shaped structure and is located on the top wall of the chassis body 1. The two ends of the drive screw 22 are rotatably connected to the bracket 21 and the bottom wall of the chassis body 1, respectively. The drive motor 23 is mounted on the side of the bracket 21 and has a bevel gear 24 on its output shaft. The bevel gear 24 meshes with the bevel gear 25 at the upper end of the drive screw 22. The lifting mechanism 2 provides a power basis for the cleaning mechanism 3 to fully cover the filter screen 11. In addition, the cleaning mechanism 3 is used to clean the filter screen 11 on the chassis body 1. The cleaning mechanism 3 includes a fixed frame 31, a dust receiving plate 34, a cleaning brush 35, a dust pump 36 and a dust collection tank 38. The fixed frame 31 has an "L" shaped structure and movable blocks 32 are bolted to both sides of it. The movable block 32 on one side of the fixed frame 31 is screwed to the drive screw 22 through a screw nut. The movable block 32 on the other side of the fixed frame 31 is slidably connected to the slide rod 33 inside the chassis body 1. The dust receiving plate 34 is disposed in the fixing frame 31. The dust receiving plate 34 is made of elastic material and has an overall arc structure. By utilizing the guiding effect of the arc surface, the swept dust is more likely to gather in the center, reducing the dust residue at the edge of the dust receiving plate 34. Meanwhile, an inlet 341 is provided between the upper side of the ash receiving plate 34 and the fixed frame 31. Two actuating plates 342 are provided and symmetrically arranged at both ends of the front side of the ash receiving plate 34, which can make the ash receiving plate 34 bend and vibrate under the action of the actuating plates 342. The cleaning brush 35 is located on the front side of the ash receiving plate 34 and abuts against the filter screen 11 on the chassis body 1. However, the dust pump 36 is located on the top of the fixed frame 31. The dust suction port of the dust pump 36 is connected to the air collection box 37 bolted to the top of the fixed frame 31 through the dust suction pipe 361. The air collection box 37 is connected to the dust inlet hole 311 on the top of the fixed frame 31. Several dust inlets 311 are provided and evenly distributed along the top of the fixed frame 31 to ensure that dust from each area of ​​the dust receiving plate 34 can be effectively sucked into the air collection box 37. The dust discharge port of the dust pump 36 is connected to the dust collection tank 38 on the top of the fixed frame 31 through the dust discharge pipe 362. The dust pump 36 forms a negative pressure passage through the air collection box 37, the dust inlet hole 311, and the dust discharge pipe 362 to efficiently suck the dust on the dust receiving plate 34 into the dust collection tank 38 and prevent secondary pollution of dust. In addition, the dust collection tank 38 is threadedly connected to the fixing seat 381 on the top of the fixing frame 31, and the top of the dust collection tank 38 is threadedly connected to the tank cover 382, ​​which facilitates regular cleaning of the dust inside the dust collection tank 38. The tank cover 382 is provided with an exhaust filter screen 383, which can ensure that the air is smoothly discharged during the dust collection process and prevent the dust inside the dust collection tank 38 from leaking out with the airflow, thus ensuring the cleanliness of the inside of the machine. Detailed implementation methods and principles: When it is necessary to clean the filter screen 11 on the chassis body 1, the lifting mechanism 2 and the cleaning mechanism 3 start working at the same time: that is, the output shaft of the drive motor 23 rotates, which drives the bevel gear 24 at its end to rotate synchronously. Since the bevel gear 24 meshes with the bevel gear 25 at the upper end of the drive screw 22, the rotation of the bevel gear 24 will drive the bevel gear 25 and the drive screw 22 fixed thereto to rotate synchronously. This causes the drive screw 22 to move the fixed frame 31 upward along the slide bar 33. During the lifting and lowering of the fixed frame 31, the cleaning mechanism 3 performs cleaning actions simultaneously: the cleaning brush 35 on the front side of the fixed frame 31 is always in contact with the surface of the filter screen 11 on the chassis body 1. As the fixed frame 31 moves, the cleaning brush 35 thoroughly cleans the dust and debris attached to the filter screen 11. The dust generated during cleaning falls directly onto the arc-shaped dust receiving plate 34 made of elastic material through the dust inlet 341. When the symmetrically arranged deflecting plates 342 at both ends of the dust receiving plate 34 move with the fixed frame 31, they are deflected by the filter holes on the filter screen 11 on the chassis body 1, causing the dust receiving plate 34 to bend and vibrate, shaking off the dust remaining on the dust receiving plate 34. During the bending process of the dust receiving plate 34, some of the dust remaining on the inner walls of both sides of the fixed frame 31 is scraped. Meanwhile, the suction port of the vacuum pump 36 is connected to the air collection box 37 on the top of the mounting frame 31 through the suction pipe 361. The air collection box 37 generates negative pressure suction through the dust inlet holes 311 evenly distributed on the top of the mounting frame 31, drawing dust from the dust collection plate 34 into the air collection box 37 through the dust inlet 341. Subsequently, the vacuum pump 36 discharges the collected dust into the dust collection tank 38 through the dust discharge pipe 362. The exhaust filter 383 on the top cover 382 of the dust collection tank 38 allows air to be discharged while preventing dust from leaking out.

[0025] After cleaning is completed, the drive motor 23 rotates in the opposite direction, causing the fixed frame 31 to reset, and then the drive motor 23 and the dust pump 36 are turned off.

[0026] After multiple cleanings, when the dust collection tank 38 is full of dust, open the main body 1 of the chassis. The dust collection tank 38 can be disassembled from the top mounting base 381 of the mounting bracket 31. Unscrew the tank cover 382 to empty the collected dust.

[0027] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
