[0017] like Figure 1-3As shown, a mini silent dustproof device for a computer of the present invention comprises a shell 1, a circulation groove 2 is arranged around the shell 1, a plurality of vents are arranged on the shell 1, a dustproof net 3 is fixedly connected to each vent, a heat absorbing plate 8 is arranged on the inner wall of the shell 1, a support base 6 is fixedly connected to the bottom side of the shell 1, and an anti-skid pattern is arranged on the support base 6. The shell 1 is raised by the support base 6 to ensure normal air circulation at the bottom vents, and the body is prevented from slipping by the anti-skid pattern. A cavity is arranged in the shell 1, exhaust fans 4 are arranged in the upper and lower sides of the cavity, and cold air fans 7 are arranged in the left and right sides of the cavity. The exhaust fan 4 and the cold air fan 7 are both silent fans. The fan reduces the noise generated during operation. An installation cavity 15 is provided on the inner wall of the housing 1. An eccentric wheel 14 is provided in the installation cavity 15. Rotary switches are embedded in the inner walls of both sides of the housing 1. The eccentric wheel 14 is fixedly connected with a rotating shaft. The rotating shaft is fixedly connected to the rotating switch. The rotating shaft is driven to rotate by rotating the rotating switch, so that the rotating shaft drives the eccentric wheel 14 to rotate. A fixed block 22 is also provided in the installation cavity 15. The fixed block 22 is rotatably connected with a second movable rod 12. The second movable rod 12 is rotatably connected with a first roller 13. The second movable rod 12 is also rotatably connected with a second roller 16. The second roller 16 is close to one side of the fixed block 22. The second movable rod 12 is rotatably connected with a first roller 13. The second movable rod 12 is also rotatably connected with a second roller 16. The second roller 16 is close to one side of the fixed block 22. One end of the first movable rod 11 away from the fixed block 22 is rotatably connected to the first movable rod 11, and one end of the first movable rod 11 away from the second movable rod 12 is rotatably connected to the connecting rod 9. One end of the connecting rod 9 is fixedly connected to the sealing plate 5. Card grooves are provided on both sides of the shell 1. The sealing plate 5 matches the card grooves. The sealing plate 5 moves downward and is inserted into the card groove to achieve a sealing effect. The other end of the connecting rod 9 is fixedly connected to the first spring 10. The first spring 10 is staggered on the left side of the first movable rod 11. A sliding rod 21 is fixedly connected to the inner wall of the installation cavity 15. The sliding rod 21 is provided with an auxiliary adjustment device. The auxiliary adjustment device includes a slider 20. The slider 20 slides on the sliding rod 21. The slider 20 is movable, a spring rod 18 is fixedly connected to the upper side of the slider 20, and the third roller 17 is rotatably connected to the spring rod 18. The third roller 17 is squeezed and contacted with the second roller 16. A second spring 19 is fixedly connected to the right side of the slider 20. The second spring 19 is sleeved on the slide bar 21. One end of the second spring 19 is fixedly connected to the inner wall of the installation cavity 15. When the second roller 16 squeezes the third roller 17, the spring rod 18 is compressed. At the same time, the slider 20 moves to the right under the action of the slide bar 21, and the second spring 19 is compressed. When the second roller 16 does not need to squeeze the third roller 17, the spring rod 18 and the second spring 19 assist the second roller 16 to return to the starting position.

[0018] In the present invention, when the user uses the device, when the temperature of other positions of the computer is too high when working for a long time, the rotating shaft is driven to rotate by turning the rotary switch, so that the rotating shaft drives the eccentric wheel 14 to rotate, thereby driving the connecting rod 9 to move downward through the first spring 10 in a compressed state, and then the connecting rod 9 drives the sealing plate 5 to move downward, and the sealing plate 5 moves downward and is stuck in the card slot to achieve a sealing effect, so that the cold air generated by the cooling fan 7 circulates in the circulation groove to achieve a circulating heat dissipation effect, and then the cold air after absorbing heat is discharged from the vent through the exhaust fan 4. After the heat dissipation is completed, the knob switch is rotated, and the eccentric wheel 14 rotates again to squeeze the first roller 13, and at the same time the second roller 16 no longer squeezes the third roller 17, and the spring rod 18 and the second spring 19 assist the second roller 16 to return to the starting position, so that the second movable rod 12 rotates, and then drives the first movable rod 11 to move, so that the connecting rod 9 drives the sealing plate 5 to move upward out of the card slot, and the first spring 10 is compressed.
