[0031] A groove A20 is provided in the middle of the other side of the baffle 18, and grooves B21 are provided at both ends of one side of the baffle 18. An adjusting shaft 22 is rotatably connected between the groove A20 and the inside of the two grooves B21.

[0032] A plurality of adjusting slot boxes 26 are fixedly installed at both ends of the chassis side panel 2 at equal distances, and a right-angled triangle fixing block 27 matching and clamping with the hook 24 is fixedly installed on the top of the adjusting slot box 26, and a transmission rack 28 located inside the adjusting slot box 26 is fixedly installed at both ends of one side of the baffle 18, and a plurality of mounting shafts 29 are rotatably connected at equal distances on the other side of the vertical air inlet 4, and the mounting shaft 29 is located below the through slot 14, and a baffle 30 is fixedly connected to the surface of the mounting shaft 29, and a torsion spring 31 is sleeved at both ends of the mounting shaft 29, and the two ends of the torsion spring 31 are respectively fixedly connected to the baffle 30 and the side wall of the vertical air inlet duct 4, and both ends of the mounting shaft 29 extend to the corresponding adjusting slot box 26 and are fixedly installed with a gear A32 meshing with the transmission rack 28, so that the through slot 14 can be covered and sealed after the frame plate 16 and the filter screen 17 are removed.

[0033] When the frame plate 16 and the filter screen 17 are inserted between the through groove 14 and the inside of the slot 15, the baffle 30 is as shown in FIG. Figure 6As shown, the torsion spring 31 is in a tightened state; when the filter screen 17 needs to be disassembled and cleaned, the toggle block 23 is toggled to rotate upward, and the rotation of the toggle block 23 drives the adjusting shaft 22 to rotate, and the rotation of the adjusting shaft 22 drives the two hooks 24 to rotate, so that the two hooks 24 are separated from the right-angled triangle fixing block 27 and the reset spring 25 is compressed; then the baffle 18 is pulled to drive the frame plate 16, the filter screen 17, the hook 24 and the transmission rack 28 to move, so that the frame plate 16 and the filter screen 17 are pulled out from the inside of the through groove 14 and the slot 15, and the movement of the transmission rack 28 drives the gear A32 to rotate, and the rotation of the gear A32 drives the installation shaft 29 and the baffle 30 to rotate, so that the baffle 30 is blocked at the through groove 14 by the torsion spring 31, thereby preventing dust and impurities from entering.

[0034] Embodiment 3, on the basis of embodiment 1, a cross 33 is fixedly installed inside the two exhaust heat outlets 7, the middle part of the cross 33 is rotatably connected to the exhaust shaft 34, the two fan blades 9 are respectively fixedly installed on the top of the two exhaust shafts 34, the middle part of the two exhaust shafts 34 is fixedly installed with a bevel gear A35, both ends of the double-output shaft motor 13 are connected to a transmission shaft 36, one end of the two transmission shafts 36 respectively extends to the inside of the two exhaust heat outlets 7 and is fixedly connected with a bevel gear B37, the two bevel gears B37 are respectively meshed with the two bevel gears A35, thereby effectively driving the two fan blades 9 to rotate for exhaust heat dissipation.

[0035] By starting the double-output shaft motor 13, the two bevel gears A35 are driven to rotate through the two transmission shafts 36. The rotation of the two bevel gears A35 will drive the two fan blades 9 to rotate. The rotation of the two fan blades 9 will discharge the hot air inside the computer case 1. The hot air is discharged through the conical air collection groove 8 and the exhaust hot port 7. After that, negative pressure will be formed inside the computer case 1, so that the external cold air will be sucked into the computer case 1 through the air inlet 5, the vertical air inlet 4 and the air supply port 6. During the inhalation process, the cold air is filtered through multiple filters 17, thereby effectively ventilating and cooling the interior of the computer case 1, and effectively avoiding the influence of dust and the like on heat dissipation.

[0036] The two transmission shafts 36 are located inside the inner cavity 12 and are fixedly installed with a disc 38. A toggle rod 39 is fixedly installed on one side of the disc 38. Two sleeves 40 are fixedly installed on one side of the inner cavity 12. Rubber pistons 41 are installed inside the two sleeves 40. Square adjustment rods 42 are movably inserted at one end of the two sleeves 40 located inside the inner cavity 12. One end of the square adjustment rod 42 is fixedly connected to the rubber piston 41, and a transmission rod 43 matching the toggle rod 39 is fixedly installed at the bottom of the other end of the square adjustment rod 42. A spring 44 is fixedly connected between one end of the rubber piston 41 and the inside of the sleeve 40. A one-way valve 45 is installed on the other end of the sleeve 40. The one-way valve 45 is located outside the computer case 1. An adjustment rack 46 is fixedly installed at one end of one side of the square adjustment rod 42.

[0037] Two transmission inner grooves 47 are provided on the upper part of the computer case 1, and the insides of the two transmission inner grooves 47 are rotatably connected with flip shafts 48 extending to the insides of the two exhaust heat ports 7, and the two protective cover plates 11 are respectively fixedly connected to the surfaces of the two flip shafts 48. The two flip shafts 48 are located inside the transmission inner grooves 47 and are fixedly installed with worm gears 49. The bottoms of the two transmission inner grooves 47 are rotatably connected with worms 50 meshing with the worm gears 49. The bottoms of the two worm gears 50 extend to the inside of the inner cavity 12 and are fixedly installed with gears B51 that match and align with the two adjustment racks 46, so that the protective cover plates 11 can be effectively rotated and adjusted.

[0038] When the dual-output shaft motor 13 is started for exhaust and heat dissipation, the rotation of the transmission shaft 36 will drive the disc 38 to rotate, and the rotation of the disc 38 will drive the toggle rod 39 to rotate in a circle, and the toggle rod 39's circular rotation will squeeze and push the transmission rod 43 to move, so that the transmission rod 43 drives the square adjustment rod 42 to insert into the interior of the sleeve 40, and the movement of the square adjustment rod 42 will drive the adjustment rack 46 to move, and the movement of the adjustment rack 46 will drive the gear B51 to drive the worm 50 to rotate, and the rotation of the worm 50 will drive the worm wheel 49 to drive the flip shaft 48 to drive the protective cover plate 11 to rotate and open, so as to facilitate the exhaust heat outlet 7 to perform exhaust and heat dissipation;

[0039] After the protective cover 11 is opened, the adjusting rack 46 will separate from the gear B51 and continue to move, and the movement of the square adjusting rod 42 will push the rubber piston 41 to move inside the sleeve 40 to compress the spring 44, and at the same time, the air will be discharged to the outside of the computer case 1 through the one-way valve 45; then the rotating toggle rod 39 will separate from the transmission rod 43 and continue to rotate in a circle, so that the transmission shaft 36 will continue to rotate to perform exhaust and heat dissipation operations;

[0040] When the toggle rod 39 is separated from the transmission rod 43, the elastic restoring force of the spring 44 causes the rubber piston 41 to slowly move back inside the sleeve 40. During the moving back process, the toggle rod 39 rotates rapidly to squeeze the transmission rod 43, so that the moving adjustment rack 46 does not contact the gear B51.

[0041] When the double-output shaft motor 13 is stopped, the double-output shaft motor 13 is controlled so that the toggle rod 39 stays at the bottom of the disc 38 without hindering the return movement of the transmission rod 43. Then the return adjustment rack 46 will contact the gear B51 and rotate the gear B51 in the reverse direction, and finally the protective cover plate 11 will rotate in the reverse direction and cover the top of the exhaust heat outlet 7 for protection.
