It can perform numerical calculations, logical calculations, and also has a storage and memory function. It is a modern intelligent electronic device that can run according to a program and automatically and quickly process a large amount of data. Among them, the host is one of the important components for computing.

[0003] When the existing computer is running, generally there is a cooling fan to cool and dissipate heat from processing components, etc. The rotation of the internal cooling fan will generate noise. At the same time, dust in the external environment will enter the computer interior. After the cooling fan stops working, the dust will fall on the cooling fan. Since the bearing of the cooling fan may increase the friction with the fan body due to the attachment of dust during long-term use, resulting in a relatively large noise. Summary of the Invention

[0004] The purpose of the present invention is to provide a computer noise reduction device to solve the problem that due to the attachment of dust to the bearing of the cooling fan during long-term use, the friction between the bearing and the fan body may increase, resulting in a relatively large noise as mentioned in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A computer noise reduction device includes a chassis and a support base movably connected to the outside of the chassis. A buffer pad is fixed to the inner wall of the support base. A through groove is opened on one outer wall of the chassis. A protection plate is installed in the through groove of the chassis. A plurality of exhaust holes are opened on the protection plate. An air intake groove is opened on the other outer wall of the chassis, and an air intake frame is fixed to the outer wall of the chassis. A moving groove is opened on the surface of the air intake frame. A filter plate is movably connected in the moving groove on the surface of the air intake frame, and a cleaning box for cleaning the filter plate is movably connected in the air intake frame; Two mounting brackets are symmetrically installed on one inner wall of the chassis. A plurality of cooling fans are installed between the two mounting brackets. A dual-axis motor is installed on the top wall of the inner cavity of the chassis. Positioning blocks are fixed to both inner walls of the chassis. A lifting screw is rotatably connected in the positioning block, and a sealing plate is threadedly connected to the outer wall of the lifting screw.

[0006] In a further embodiment, limiting grooves are opened on both outer walls of the air intake frame. A limiting slider fixedly connected to the cleaning box is movably connected in the limiting grooves of the air intake frame.

[0007] In a further embodiment, a moving hole is formed in an outer wall of one side of the cleaning box, a connecting rod is movably connected in the moving hole of the cleaning box, and a cleaning plate is fixed to one end of the connecting rod.

[0008] In a further embodiment, a plurality of bristles are installed at one end of the cleaning plate away from the connecting rod, and a cleaning hole for the bristles to move is formed in an outer wall of one side of the cleaning box. A support spring for supporting the cleaning plate is sleeved outside the connecting rod.

[0009] In a further embodiment, rotating shafts are fixed to both ends of the double-shaft motor, a driving bevel gear is fixed to an outer wall of the rotating shaft, and a driven bevel gear meshing with the driving bevel gear is fixed to the top of the lifting screw rod.

[0010] In a further embodiment, an installation groove is formed in a bottom wall of the air intake frame, and a magnetic attraction block I that adsorbs to the filter plate is installed in the installation groove of the air intake frame.

[0011] In a further embodiment, a dust collection box is movably connected to the bottom of the air intake frame, and a plurality of installation holes are formed in a surface of the dust collection box. A magnetic attraction block II that adsorbs to the air intake frame is installed in the installation holes on the surface of the dust collection box.

[0012] In a further embodiment, a shock-absorbing pad is fixed to an outer wall of one side of the installation frame, and the air intake frame is installed outside an air intake groove of the computer case.

[0013] Technical effects and advantages of the present invention: In the computer noise reduction device, through the setting of the filter plate, during the operation of the computer, dust can be prevented from entering the computer case. After the computer finishes working, the double-shaft motor drives the rotating shaft and the driving bevel gear to rotate, and the driving bevel gear drives the lifting screw rod to rotate through the driven bevel gear, thereby driving the sealing plate to automatically descend to seal the air intake groove and the exhaust hole of the computer case, preventing dust from entering the computer case and falling on the heat dissipation fan when the computer is not working, which may increase the friction between the bearing of the heat dissipation fan and the fan body, thereby generating a relatively large noise. When the computer is not working, by moving the cleaning box up and down, the bristles in the cleaning box move on the outer wall of the filter plate to automatically clean the dust on the outer wall of the filter plate, preventing the dust from blocking the filter plate and affecting the heat dissipation effect of the computer. Through the setting of the buffer pad, the vibration generated during the operation of the computer can be reduced, thereby achieving a certain noise reduction effect. At the same time, the shock-absorbing pad can reduce the vibration generated during the operation of the heat dissipation fan, further reducing the noise generated during the operation of the computer. By pulling the connecting rod, the cleaning plate is driven to move back and forth in the cleaning box, so that the bristles on the cleaning plate move back and forth in the cleaning holes of the cleaning box, automatically cleaning the bristles and ensuring the subsequent cleaning effect of the bristles. This computer noise reduction device not only has a good noise reduction effect, but also has a good dust prevention effect. BRIEF DESCRIPTION OF THE DRAWINGS

An installation groove is provided on the bottom wall of the inner cavity of the air intake frame 5, and a magnetic attraction block one 7 that adsorbs to the filter plate 6 is adhesively bonded in the installation groove of the air intake frame 5. Through the magnetic attraction block one 7, the position of the filter plate 6 can be fixed to ensure the stability of the filter plate 6. Through the arrangement of the filter plate 6, during the operation of the computer, dust can be prevented from entering the chassis 1; A cleaning box 8 for cleaning the filter plate 6 is movably connected inside the air intake frame 5. Limiting grooves are provided on the outer walls on both sides of the air intake frame 5.

The limiting slider 9 can limit the movement path of the cleaning box 8 and ensure the stability of the cleaning box 8 during movement. A moving hole is provided on the outer wall of one side of the cleaning box 8. A connecting rod 10 is movably connected in the moving hole of the cleaning box 8. One end of the connecting rod 10 is fixed with a cleaning plate 11. A plurality of bristles are installed at the end of the cleaning plate 11 away from the connecting rod 10. A cleaning hole for the bristles to move is provided on the outer wall of one side of the cleaning box 8. The bristles are in contact with the filter plate 6. A support spring 12 for supporting the cleaning plate 11 is sleeved on the outer part of the connecting rod 10. The support spring 12 supports the cleaning plate 11, enabling the bristles to always be in contact with the filter plate 6. A handle is fixedly connected to the outer wall of one side of the cleaning box 8 by bolts, which facilitates driving the cleaning box 8 to move; A dust collection box 13 is movably connected to the bottom of the air intake frame 5. A plurality of mounting holes are provided on the surface of the dust collection box 13. A second magnetic attraction block 14 that adsorbs to the air intake frame 5 is installed in the mounting holes on the surface of the dust collection box 13. By the mutual adsorption of the second magnetic attraction block 14 and the air intake frame 5, it is convenient to disassemble and assemble the dust collection box 13. A dust outlet groove is provided at the bottom of the air intake frame 5. When cleaning the filter plate 6, the dust can quickly fall into the dust collection box 13. When the computer is not working, by moving the cleaning box 8 up and down, the bristles in the cleaning box 8 move on the outer wall of the filter plate 6 to automatically clean the dust on the outer wall of the filter plate 6, preventing the dust from blocking the filter plate 6 and affecting the heat dissipation effect of the computer. By pulling the connecting rod 10, the cleaning plate 11 is driven to move back and forth in the cleaning box 8, so that the bristles on the cleaning plate 11 move back and forth in the cleaning hole of the cleaning box 8 to automatically clean the bristles and ensure the subsequent cleaning effect of the bristles; Two mounting brackets 15 are symmetrically installed on one inner wall of the chassis 1 by bolts. The two mounting brackets 15 are located on both sides of the air intake groove respectively. A plurality of heat dissipation fans 16 are installed between the two mounting brackets 15 by bolts. A shock pad 17 is bonded to the outer wall of one side of the mounting bracket 15. The shock pad 17 can reduce the vibration generated when the heat dissipation fan 16 works and further reduce the noise generated when the computer works; The top wall of the inner cavity of the chassis 1 is installed with a double-shaft motor 18 through bolts. Both ends of the double-shaft motor 18 are fixed with rotating shafts 19 through couplings. The outer wall of the rotating shaft 19 is welded with a driving bevel gear 20. Positioning blocks 21 are welded on both inner walls of the chassis 1. A lifting screw rod 22 is rotatably connected in the positioning block 21 through a bearing. The top of the lifting screw rod 22 is welded with a driven bevel gear 23 that meshes with the driving bevel gear 20. The outer wall of the lifting screw rod 22 is threadedly connected with a sealing plate 24. The thread groove directions of the two driving bevel gears 20, the driven bevel gear 23 and the lifting screw rod 22 can be set according to actual use requirements. When the double-shaft motor 18 works, it is ensured that the two sealing plates 24 move vertically in the chassis 1. The size of the sealing plate 24 can be set according to actual use requirements, and the sealing plate 24 can move between the two mounting brackets 15, and at the same time can seal the air inlet groove and the exhaust hole of the chassis 1. After the computer finishes working, the double-shaft motor 18 drives the rotating shaft 19 and the driving bevel gear 20 to rotate. The driving bevel gear 20 drives the lifting screw rod 22 to rotate through the driven bevel gear 23, thereby driving the sealing plate 24 to automatically descend to seal the air inlet groove and the exhaust hole of the chassis 1, avoiding dust from the outside entering the chassis 1 and falling on the cooling fan 16 when the computer is not working, resulting in an increase in the friction between the bearing of the cooling fan 16 and the fan body, and thus generating a relatively large noise.

The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, welding, etc. that are mature in the prior art.

[0021] In the description of the present invention, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0022] Working principle: When in use, the computer noise reduction device starts the cooling fan 16 during the operation of the computer to cool the electronic components in the chassis 1 and discharge the heat in the chassis 1 through the exhaust holes. The buffer pad 3 can reduce the vibration generated during the operation of the computer, thus achieving a certain noise reduction effect. At the same time, the shock pad 17 can reduce the vibration generated during the operation of the cooling fan 16, further reducing the noise generated during the operation of the computer; When the computer finishes working, the biaxial motor 18 drives the rotating shaft 19 and the driving bevel gear 20 to rotate. The driving bevel gear 20 drives the lifting screw 22 to rotate through the driven bevel gear 23, thereby driving the sealing plate 24 to automatically descend to seal the air inlet groove and the exhaust holes of the chassis 1, preventing dust from the outside from entering the chassis 1 and falling on the cooling fan 16 when the computer is not working, which may increase the friction between the bearing and the fan body of the cooling fan 16, thus generating a relatively large noise; Move the cleaning box 8 up and down so that the bristles in the cleaning box 8 move on the outer wall of the filter plate 6 to automatically clean the dust on the outer wall of the filter plate 6, preventing the filter plate 6 from being blocked by dust and affecting the heat dissipation effect of the computer. After the cleaning of the filter plate 6 is completed, by pulling the connecting rod 10, the cleaning plate 11 is driven to move back and forth in the cleaning box 8, so that the bristles on the cleaning plate 11 move back and forth in the cleaning holes of the cleaning box 8 to automatically clean the bristles and ensure the subsequent cleaning effect of the bristles. The dust is collected by the dust collection box 13.
