The pressing roller 331 is provided with two groups and is in the inner cavity of the filter 31. The extrusion part 332 is located on the inner wall of the box door 2 and is connected to the pressing roller 331. The extrusion part 332 is used to apply a thrust to the pressing roller 331 so that the filter 31 fits the inner wall of the box door 2. The dust removal component 34 includes a cleaning part 341 and a guide part 342. The cleaning part 341 is located in the fixed box 22. The cleaning part 341 controls the rotation of the filter 31 by cooperating with the positioning component 32 and cleans the dust and impurities attached to the surface of the filter 31 in the fixed box 22. The guide part 342 is located on the surface of the box door 2. The guide part 342 is used to remove the dust and impurities cleaned in the fixed box 22.

[0026] The positioning assembly 32 supports and positions the filter 31 on the inner side of the door 2, and the filter 31 maintains a double-layer vertical state. The extrusion portion 332 applies a thrust to the pressing roller 331 on the inner side of the door 2, and the pressing roller 331 presses the filter 31. The filter 31 fits the side wall of the door 2. When the inner cavity of the chassis 1 is blown and cooled, the air flows through the heat dissipation holes 21 on the surface of the door 2. When the air flows, the filter 31 can filter the dust impurities in the air. The dust impurities adhere to the surface of the filter 31. When the dust impurities adhere to the surface of the filter 31 After reaching a certain level, the cleaning portion 341 cooperates with the positioning assembly 32 to control the filter 31 to rotate inside the box door 2, and the filter 31 can continuously pass through the fixed box 22. When the filter 31 rotates, the cleaning portion 341 can automatically clean the dust impurities attached to the surface of the filter 31 in the fixed box 22. The cleaned dust impurities fall into the fixed box 22. The cleaned filter 31 continues to rotate and move to the outside of the fixed box 22 and clings to the inner wall of the box door 2. The filter 31 can continuously filter the dust impurities in the air. When the dust impurities accumulated in the fixed box 22 reach a certain level, the guide portion 342 can conveniently remove the dust impurities in the fixed box 22.

[0027] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, as a preferred embodiment of the present invention, the positioning assembly 32 includes an upper support roller 321 rotatably installed on the inner side of the box door 2 and located above the heat dissipation hole 21, and a lower support roller 322 is rotatably installed in the fixed box 22. The filter screen 31 is sleeved between the upper support roller 321 and the lower support roller 322. A long strip-shaped opening 323 is provided on the surface of the fixed box 22 and cooperates with the filter screen 31.

[0028] When in use, the upper support roller 321 and the lower support roller 322 cooperate with each other to stably support and position the filter 31 on the inside of the box door 2, so that the filter 31 maintains a double-layer vertical state on the inside of the box door 2, and the filter 31 can filter and remove impurities in all directions on the air flowing in the heat dissipation hole 21. When it is necessary to clean the dust and impurities attached to the surface of the filter 3, the cleaning part 341 controls the lower support roller 322 to rotate in the fixed box 22. The lower support roller 322 and the upper support roller 321 cooperate with each other to control the filter 31 to rotate on the inside of the box door 2. The filter 31 passes through the fixed box 22 when rotating. The cleaning part 341 can automatically clean the dust and impurities attached to the surface of the filter 31 in the fixed box 22.

[0029] like Figure 2 、 Figure 4 、 Figure 6 As shown, as a preferred embodiment of the present invention, the extrusion portion 332 includes multiple groups of side panels 3321 fixedly installed on the inner wall of the box door 2, which are respectively located on both sides of the filter screen 31, and the two opposite side walls of the two groups of side panels 3321 are respectively provided with a slide groove 3322, and a sliding block 3323 is slidably installed in the slide groove 3322. The pressing roller 331 is rotatably installed between the two groups of sliding blocks 3323, and an extrusion spring 3324 is fixedly installed on the end of the slide groove 3322 away from the box door 2, and the telescopic end of the extrusion spring 3324 is connected to the sliding block 3323.

[0030] When in use, the extrusion spring 3324 applies a thrust to the sliding block 3323, and the two groups of sliding blocks 3323 cooperate with each other to apply a thrust to the pressing roller 331, and the pressing roller 331 presses the filter 31, so that the filter 31 fits against the inner wall of the door 2. At this time, the heat dissipation holes 21 and the filter 31 fit together synchronously, which can effectively avoid the existence of gaps between the heat dissipation holes 21 and the filter 31, and thus avoid air flowing through the gaps between the heat dissipation holes 21 and the filter 31. The filter 31 can comprehensively screen and filter dust impurities in the air.

[0031] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, as a preferred embodiment of the present invention, the cleaning part 341 includes a rotating rod 3411 rotatably installed in the inner cavity of the fixed box 22 and located below the lower support roller 322, and a plurality of groups of evenly distributed brushes 3412 are provided on the surface of the rotating rod 3411, and a first transmission gear disc 3413 is fixedly installed on the surface of the lower support roller 322, and a second transmission gear disc 3414 is fixedly installed on the surface of the rotating rod 3411, and the second transmission gear disc 3414 is meshed with the first transmission gear disc 3413. One end of the rotating rod 3411 extends to the outside of the fixed box 22 and is connected to a motor 3415.

[0032] During use, the motor 3415 drives the rotating rod 3411 to rotate and then drives the second transmission gear plate 3414 to rotate. The second transmission gear plate 3414 engages with the first transmission gear plate 3413 for transmission, which can drive the lower support roller 322 to rotate. The lower support roller 322 and the upper support roller 321 cooperate with each other to drive the filter screen 31 to rotate. While the filter screen 31 is rotating, the rotating rod 3411 drives the brush 3412 to rotate synchronously. The brush 3412 can automatically clean the dust and impurities attached to the surface of the filter screen 31 in the fixed box 22.

[0033] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, as a preferred embodiment of the present invention, the guide portion 342 includes a guide port 3421 opened inwardly on the surface of the box door 2 and connected to the fixed box 22 , and a sealing strip 3422 is detachably installed in the guide port 3421 .

[0034] Initially, the sealing strip 3422 is plugged into the exhaust port 3421 , and the exhaust port 3421 is in a closed state. When the dust impurities in the fixed box 22 reach a certain level, the sealing strip 3422 is removed, and the dust impurities can be easily removed from the fixed box 22 through the exhaust port 3421 .

[0035] like Figure 2 、 Figure 3 As shown, as a preferred embodiment of the present invention, two groups of fixed rollers 4 located on both sides of the filter screen 31 are rotatably installed in the inner cavity of the fixed box 22, and two groups of scrapers 5 located on both sides of the filter screen 31 are fixedly installed in the inner cavity of the fixed box 22, and the fixed rollers 4 and scrapers 5 are respectively located under the two groups of openings 323.

[0036] When the brush 3412 cleans the filter 31 in the fixed box 22, the two sets of fixed rollers 4 and the two sets of scrapers 5 can seal the bottom of the opening 323, effectively preventing the dust and impurities cleaned from passing through the opening 323 and drifting into the inner cavity of the chassis 1.

[0037] like Figure 1 、 Figure 2 As shown in FIG. 1 , as a preferred embodiment of the present invention, support legs 6 are respectively provided around the bottom wall of the chassis 1, and rollers 7 are rotatably mounted on the bottom ends of the support legs 6. By cooperating with the support legs 6 and the rollers 7, the position of the chassis 1 can be conveniently adjusted.

[0038] like Figure 3 、 Figure 4 As shown in FIG. 1 , as a preferred embodiment of the present invention, the bottom end of the fixed box 22 is configured as an inclined structure. The inclined fixed box 22 can conveniently discharge dust and impurities through the exhaust port 3421 .

[0039] The working principle of the present invention is as follows: when in use, the upper support roller 321 and the lower support roller 322 cooperate with each other to stably support and position the filter 31 on the inner side of the box door 2, so that the filter 31 maintains a double-layer vertical state on the inner side of the box door 2, and the pressing roller 331 presses the filter 31 so that the filter 31 fits the inner wall of the box door 2. At this time, the heat dissipation holes 21 and the filter 31 fit synchronously. When the inner cavity of the chassis 1 is blown and cooled, the air flows through the heat dissipation holes 21 on the surface of the box door 2. When the air flows, the filter 31 can filter the dust impurities in the air, and the dust impurities attached to the filter 31 are removed. When the dust impurities adhering to the surface of the filter 31 reach a certain level, the motor 3415 drives the rotating rod 3411 to rotate, thereby driving the second transmission gear plate 3414 to rotate. The second transmission gear plate 3414 engages with the first transmission gear plate 3413 to drive the lower support roller 322 to rotate. The lower support roller 322 cooperates with the upper support roller 321 to drive the filter 31 to rotate. As the filter 31 rotates, the rotating rod 3411 drives the brush 3412 to rotate synchronously. The brush 3412 can automatically clean the dust impurities adhering to the surface of the filter 31 in the fixed box 22. The cleaned dust impurities fall into the fixed box 22. The cleaned filter 31 continues to rotate and moves to the outside of the fixed box 22 and is closely attached to the inner wall of the door 2. The filter 31 can continuously filter the dust impurities in the air. When the dust and impurities accumulated in the fixed box 22 reach a certain level, the sealing strip 3422 is removed, and the dust and impurities can be conveniently taken out of the fixed box 22 through the exhaust port 3421 .

[0040] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
