[0026] As Figures 1 to 5 shown, a lifting machine room mist exhaust ventilation device, including mist exhaust mechanism 2 and air inlet mechanism 3, mist exhaust mechanism 2 and air inlet mechanism 3 are fixedly installed on the side wall surface of the machine room wall body 1 in the form of axis diagonal line, mist exhaust mechanism 2 is sequentially fixedly connected from inside to outside of the machine room wall body 1 by filter box 5, fan box 6, check box 7 and air collecting port 8, air inlet mechanism 3 is sequentially fixedly connected from inside to outside of the machine room wall body 1 by fan box 6, filter box 5 and air collecting port 8, mist exhaust mechanism 2, air inlet mechanism 3 and the wall between the machine room wall body 1 are fixedly connected with fixed mechanism 4, the surface of check box 7 is provided with mounting hole 9, the inner wall side of mounting hole 9 is fixedly installed with ventilation pipe 11 and elastic blocking assembly 10 for elastically blocking ventilation pipe 11, filter box 5 inner wall surface is slidably installed with filter box 12, filter box 12 bottom surface is fixedly installed with elastic clamping assembly 13, and elastic clamping assembly 13 is elastically clamped in the side wall of filter box 5.

[0027] More specifically, when the external air enters the machine room wall 1 through the air inlet mechanism 3, it successively passes through the air inlet mechanism 3, the filter box 5 and the fan box 6, so that the air entering the machine room wall 1 through the mist exhaust mechanism 2 is fully purified by the filter box 5 surface filter box 12. When the mist and air are discharged through the air inlet mechanism 3, they successively pass through the filter box 5, the fan box 6, the check box 7 and the air collecting port 8, and the elastic blocking assembly 10 is driven to elastically move by the pressure difference, thereby elastically blocking the ventilation pipe 11. When the external air pressure is greater than the air pressure inside the machine room wall 1, and the fan box 6 cannot normally discharge the air, the elastic blocking assembly 10 blocks the ventilation pipe 11 under the action of the pressure difference, so that the external air cannot flow back to the inside of the machine room wall 1 through the installation hole 9 and the ventilation pipe 11. When the internal and external pressure difference is normal, the elastic blocking assembly 10 is driven away from the ventilation pipe 11 by the working of the fan box 6, so that the air in the machine room wall 1 can be discharged through the ventilation pipe 11 and the installation hole 9. The cooperation of the elastic blocking assembly 10 and the ventilation pipe 11 effectively prevents air backflow, effectively ensures the air cleanliness and temperature and humidity stability inside the machine room wall 1. The elastic blocking assembly 13 is elastically clamped in the filter box 5, so that the filter box 12 is fixed in the filter box 5. When the filter box 12 needs to be cleaned, the elastic clamping assembly 13 can be quickly disassembled, which has the advantages of convenient disassembly and cleaning of the filter box 12.

[0028] The fixing mechanism 4 comprises a lower fixed plate 401 and an upper fixed plate 402, and a connecting rod 403 is fixedly connected between the lower fixed plate 401 and the upper fixed plate 402. The lower fixed plate 401 and the upper fixed plate 402 are both provided with fixed screws 404. The fixed screws 404 are respectively threadedly connected with the surface of the mist exhaust mechanism 2, the surface of the air inlet mechanism 3 and the surface of the machine room wall 1.

[0029] Specifically, the lower fixed plate 401 is fixedly connected with the wall of the machine room wall 1 and the surface of the mist exhaust mechanism 2 or the surface of the air inlet mechanism 3 by the fixed screws 404, thereby reinforcing the mist exhaust mechanism 2 and the air inlet mechanism 3, and ensuring that the mist exhaust mechanism 2 and the air inlet mechanism 3 work stably and reliably.

[0030] The elastic blocking assembly 10 comprises a cross 101, the cross 101 is fixedly installed on the inner wall side of the installation hole 9, and a slide column 102 is fixedly connected between the left and right two crosses 101. A blocking ball 103 is slidably installed on the surface of the slide column 102. The diameter of the blocking ball 103 is the same as the inner diameter of the ventilation pipe 11. A first spring 104 is fixedly connected to the surface of the blocking ball 103 away from the ventilation pipe 11. The first spring 104 is fixedly connected to the surface of the cross 101. When the first spring 104 is at the natural length, the blocking ball 103 is located at the port of the ventilation pipe 11.

[0031] Specifically, the air flow generated by the air pressure difference pushes the blocking ball 103 to slide along the surface of the slide column 102, when the air flows from the inside to the outside of the computer room wall 1, the blocking ball 103 is pushed to the left, so that the first spring 104 is compressed, at this time the air in the computer room wall 1 can be discharged to the air collecting port 8 through the ventilation pipe 11 and the mounting hole 9, and finally to the outside of the computer room wall 1, when the air flows from the outside to the inside of the computer room wall 1, the blocking ball 103 is pushed to slide to the right, and the blocking ball 103 is initially located at the port of the ventilation pipe 11, so when the blocking ball 103 moves into the ventilation pipe 11, it will continuously block the ventilation pipe 11, and due to the limiting of the cross 101, the blocking ball 103 will not come off from the ventilation pipe 11, thereby avoiding the inflow of external air into the computer room wall 1 and preventing air backflow.

[0032] The filter box 12 comprises two mounting plates 121 arranged opposite to each other, and an activated carbon bag 122 and a dust filter sheet 123 are fixedly connected between the opposite surfaces of the two mounting plates 121, the dust filter sheet 123 is arranged on the surfaces on the left and right sides of the activated carbon bag 122, and the mounting plates 121 are slidingly arranged on the side surfaces of the filter box 5.

[0033] Specifically, the dust filter sheet 123 filters the dust in the air, and the activated carbon bag 122 further adsorbs the dust while dehumidifying, thereby ensuring the stability of the air humidity in the computer room wall 1 and avoiding rapid changes in the air humidity in the computer room wall 1.

[0034] The elastic clamping assembly 13 comprises a mounting block 131 slidingly mounted on the side wall of the filter box 5, the mounting plate 121 is fixedly mounted on the surface of the mounting block 131, a T-shaped sliding groove 132 is formed in the bottom surface of the mounting block 131, a T-shaped sliding block 133 is slidingly mounted on the inner wall surface of the T-shaped sliding groove 132, the number of the T-shaped sliding blocks 133 is two and they are symmetrically arranged, a second spring 134 is fixedly connected between the opposite surfaces of the two T-shaped sliding blocks 133, and an insertion block 135 is fixedly mounted on the opposite surfaces of the two T-shaped sliding blocks 133, the insertion block 135 is slidingly inserted into the side wall of the mounting block 131, the side wall of the filter box 5 is provided with an insertion slot 14 for accommodating the insertion block 135, and the insertion block 135 is slidingly inserted into the inner wall surface of the insertion slot 14.

[0035] Specifically, the two T-shaped sliding blocks 133 are pinched towards each other, so that the second spring 134 is compressed, and at the same time, the two insertion blocks 135 move towards each other, so that the insertion blocks 135 retract into the mounting block 131, so that the mounting block 131 can be smoothly slidingly inserted into the filter box 5, thereby driving the filter box 12 to enter or exit the filter box 5, when it is necessary to fix the filter box 12, the T-shaped sliding blocks 133 are loosened, so that the second spring 134 rebounds, driving the insertion blocks 135 to slidingly insert into the insertion slot 14, completing the fixation of the elastic clamping assembly 13, and thus the fixation of the filter box 12 is completed.

[0036] The fan body 15 is fixedly installed on the surface of the fan box 6.

[0037] Specifically, the fan body 15 drives air flow, and air inside and outside the computer room wall 1 is exchanged to adjust the air temperature and humidity in the computer room wall 1.

[0038] In summary, the elastic blocking assembly 10 is driven by the pressure difference to be elastically movable, thereby elastically blocking the ventilation pipe 11. When the external air pressure is greater than the air pressure inside the computer room wall 1, and the air cannot be normally discharged through the operation of the fan box 6, the elastic blocking assembly 10 blocks the ventilation pipe 11 under the action of the pressure difference, so that the external air cannot flow into the computer room wall 1 through the installation hole 9 and the ventilation pipe 11. When the internal and external pressure difference is normal, the elastic blocking assembly 10 is driven by the operation of the fan box 6 to be away from the ventilation pipe 11, so that the air inside the computer room wall 1 can be discharged through the ventilation pipe 11 and the installation hole 9. The elastic blocking assembly 10 and the ventilation pipe 11 are matched to effectively prevent air from flowing backward, and effectively ensure the air cleanliness and the temperature and humidity stability inside the computer room wall 1.
