A collection device for collecting dust is arranged inside the second rectangular hole 10;

[0040] Among them, a dust cleaning device is provided between the front surface of the host chassis 1 and the dustproof net 6;

[0041] Among them, fixing devices for limiting the dustproof net 6 are arranged at the front and rear ends of the upper surface of the host chassis 1.

[0042] Furthermore, the sliding device includes two first rectangular holes 5, which are correspondingly opened at the front and rear ends of the upper surface of the host chassis 1 and correspond to the positions of the two dustproof nets 6;

[0043] The first sliding grooves 7 are respectively provided on the left and right sides of the two first rectangular holes 5, and the first sliding grooves 7 are slidably installed with first sliding blocks 8 adapted thereto, and the corresponding ends of the two first sliding blocks 8 are fixedly connected to the left and right sides of the dustproof net 6;

[0044] Wherein, a handle 4 is fixedly installed at the middle position of the top of the two dustproof nets 6.

[0045] Further, the collecting device includes two second chutes 11, and the two second chutes 11 are correspondingly opened on the left and right inner walls of the second rectangular hole 10, and the second sliders 12 are slidably installed inside the two second chutes 11, and the corresponding ends of the two second sliders 12 are fixedly connected to the dust storage hopper 9, and the dust storage hopper 9 is slidably connected to the inside of the second rectangular hole 10;

[0046] The dust storage hopper 9 is V-shaped, which can prevent dust from accumulating at both ends of the dust storage hopper 9 and avoid blockage.

[0047] Among them, a similar handle 4 is fixedly installed at the middle position of the outer surface of the dust storage hopper 9.

[0048] Furthermore, the dust cleaning device includes a hydraulic telescopic rod 24, which is fixedly mounted on the inner wall of the upper surface of the host chassis 1, and a scraper 15 is fixedly mounted on the telescopic end of the hydraulic telescopic rod 24;

[0049] Among them, the scraper 15 is fixedly installed with bristles 16 at one end close to the dustproof net 6, and the bristles 16 are arranged in close contact with the dustproof net 6 at one end away from the scraper 15.

[0057] Working principle: When using this device, when dust needs to be cleaned, shut down the computer and start the hydraulic telescopic rod 24. The telescopic end of the hydraulic telescopic rod 24 drives the scraper 15 to move up and down, and further drives the bristles 16 thereon to move up and down to clean the dust. The dust falls into the dust hopper 9, and then the handle 4 is used to pull the dust hopper 9 out of the second rectangular hole 10, making maintenance more convenient, reducing maintenance costs and time, and effectively reducing the accumulation of dust inside the host.

[0058] When the dustproof net 6 needs to be removed, pull the limiting column 21 backward to pull the dustproof net 6 out of the first rectangular hole 5, loosen the limiting column 21, and the limiting column 21 returns to its original position under the rebound of the spring 18. The detachable dustproof net 6 can be easily removed and cleaned or replaced, making maintenance more convenient and reducing maintenance costs and time.

[0059] When it is necessary to install and fix the dustproof net 6, pull the limiting column 21 backward to install the dustproof net 6 in the first rectangular hole 5, and the first sliders 8 on the left and right sides of the dustproof net 6 slide in the first slide groove 7.
