When the dustproof filter screen 35 needs to be cleaned, the cleaning mechanism 32 located on the rear end of the side of the computer case 1 close to the dustproof filter screen 35 can play a role, the cleaning end of the cleaning mechanism 32 is in abutting connection with the outer surface of the dustproof filter screen 35, and the dust and impurities attached to the dustproof filter screen 35 can be cleaned, so that the good ventilation and filtering performance of the dustproof filter screen 35 can be maintained. When the dustproof filter screen 35 needs to be removed for maintenance or replacement, the limiting mechanism 33 on the middle part of the side of the computer case 1 close to the dustproof filter screen 35 can release the fixing limitation of the dustproof filter screen 35, so that the operator can pull out the dustproof filter screen 35 from the inner side of the guide rails 31 through the sliding sliding plate 34, and the removal operation is completed.

[0029] Reference Figures 1-3 and Figure 6The limiting mechanism 33 comprises a sliding groove 331 and a clamping groove 332.

At this time, the dustproof filter screen 35 can be pulled out from the inner side of the guide rail 31 through the sliding sliding plate 34, so that convenient removal is realized. The decorative cover plate 336 can not only shield the sliding groove 331 to avoid dust from entering and affecting the normal operation of the mechanism, but also improve the appearance of the computer case to a certain extent.

[0030] Reference Figures 1-2 and Figures 4-5The cleaning mechanism 32 comprises an upright rail 321 fixedly installed on one side of the computer case 1 close to the heat dissipation window 2, an internal rotating connection of the upright rail 321 has a lead screw 322, the top of the upright rail 321 is fixedly connected with a driving motor 323, the output end of the driving motor 323 is connected through the top of the upright rail 321 and the lead screw 322, the outer surface of the lead screw 322 is threadedly connected with a sliding block 324, the front surface of the sliding block 324 is fixedly connected with a brush wiping assembly 325, the brush wiping assembly 325 comprises a mounting rail 3251, an internal sliding connection of the mounting rail 3251 has a mounting strip 3252, the mounting strip 3252 is fixedly connected with a brush plate 3253 close to one side of the dustproof filter screen 35, the brush plate 3253 is attached to the outer surface of the dustproof filter screen 35, the rear end of the mounting strip 3252 is threadedly connected with a mounting screw 3254, the end of the mounting screw 3254 is threadedly connected with the mounting rail 3251, when the dustproof filter screen 35 needs to be cleaned, the driving motor 323 located at the top of the upright rail 321 is started, after the driving motor 323 operates, the output end drives the lead screw 322 to rotate in the upright rail 321, since the lead screw 322 is threadedly connected with the sliding block 324, the rotation of the lead screw 322 drives the sliding block 324 to move up and down along the length direction of the upright rail 321, the brush wiping assembly 325 fixedly connected to the front surface of the sliding block 324 moves together with the sliding block 324, wherein the brush plate 3253 is attached to the outer surface of the dustproof filter screen 35, during the movement process, the dustproof filter screen 35 is brushed to clean the dust and impurities attached to the filter screen, if the brush plate 3253 needs to be replaced due to wear after long-term use, the mounting screw 3254 can be twisted to achieve replacement, the mounting screw 3254, the rear end of the mounting strip 3252 and the mounting rail 3251 are all threadedly connected, rotating the mounting screw 3254 makes it gradually move outward, when the mounting screw 3254 is separated from the mounting rail 3251 to a certain extent, the mounting strip 3252 can be pulled out from the inside of the mounting rail 3251, and then the mounting strip 3252 with a new brush plate 3253 can be conveniently replaced, so that the cleaning mechanism 32 can always efficiently clean the dustproof filter screen 35, maintain good working condition of the filter screen and ensure the heat dissipation effect of the computer case 1.

[0031] Reference Figures 3-5, the top of the computer case 1 is hinged with a bridge handrail 5, the bottom of the computer case 1 is fixedly connected with a base 4, the bottom of the base 4 is provided with anti-skid stripes at equal intervals, the mounting screw 3254 is provided as a hand screw, which greatly improves the convenience of operation. When it is necessary to replace the mounting strip 3252 in the brush wiping assembly 325, the operator does not need to use additional tools, but can directly hold the hand screw 3254 and rotate it. By rotating the mounting screw 3254 clockwise or counterclockwise, the position of the screw connection between the mounting screw 3254 and the mounting rail 3251 is changed, so that the mounting screw 3254 is easily moved outward or rotated inward, thereby quickly extracting or inserting the mounting strip 3252 from the inside of the mounting rail 3251, facilitating the replacement of the worn brush plate 3253. The bridge handrail 5 hinged at the top of the computer case 1 mainly provides convenience for carrying or moving the case. When it is necessary to move the case, the operator can hold the bridge handrail 5 and lift or push the case by applying force. The handrail changes the direction of the applied force, making the operation more labor-saving and facilitating the adjustment of the position of the case. The base 4 fixedly connected to the bottom of the case has anti-skid stripes at equal intervals on the bottom, which plays a role in stable support. When the case is placed, the anti-skid stripes increase the friction between the base 4 and the placement plane, effectively preventing the case from sliding or moving due to external forces such as vibration and collision during use, ensuring that the case is always in a stable state and ensuring the normal operation of the internal hardware.

[0032] Principle and advantages: The device innovatively provides a filter screen device 3, which greatly improves the cleaning and maintenance efficiency of the dustproof filter screen 35 during use. During actual use, when it is necessary to clean the dustproof filter screen 35, the driving motor 323 can be started. After the driving motor 323 operates, the lead screw 322 is driven to rotate, and the rotation of the lead screw 322 causes the sliding block 324 to slide directionally inside the vertical rail 321. Through the sliding of the sliding block 324 inside the vertical rail 321, the installation strip 3252 inside the installation rail 3251 mounted on the sliding block 324 can be further driven to move. As the installation strip 3252 moves up and down in the vertical direction, the brush plate 3253 fixed on the installation strip 3252 can be closely attached to the outer surface of the dustproof filter screen 35 and brushed during movement. By controlling the driving motor 323 to alternately rotate in the reverse direction and the forward direction, the lead screw 322 can drive the brush plate to reciprocatingly move up and down on the surface of the dustproof filter screen 35. This reciprocating brushing method can comprehensively and efficiently clean the dustproof filter screen 35, effectively removing dust and other impurities attached to the surface of the filter screen, and ensuring that the dustproof filter screen 35 always maintains good filtering performance.

[0033] In addition, when the brush plate needs to be replaced due to wear during long-term use, the operation process is extremely simple. Only need to twist the hand-tightening mounting screw 3254 to make it rotate. During the rotation process, the mounting screw 3254 gradually moves outward, and then the mounting strip 3252 on the brush plate can be smoothly pulled out from the inside of the mounting rail 3251. This design enables the overall device to quickly complete the replacement of the brush plate 3253 during use, greatly improving the convenience and maintenance efficiency of the device;

[0034] The limiting mechanism 33 provided by the device provides great convenience for the removal and installation of the dust filter screen 35 and the overall maintenance of the computer case 1, while also considering aesthetics. When the dust filter screen 35 needs to be removed for maintenance, first push the decorative cover plate 336 with the non-slip push plate 337. During the pushing process, the movement of the decorative cover plate 336 will drive the movement of the movable block 334 synchronously. The movement of the movable block 334 will cause the limiting spring 333 to be extruded, causing the limiting spring 333 to contract. During the contraction of the limiting spring 333, the limiting pin 335 can be pulled out to disengage from the inside of the clamping groove 332. When the limiting pin 335 successfully disengages from the clamping groove 332, the dust filter screen 35 can be pulled out. At this time, the dust filter screen 35 is pulled out while the slide plate 34 at the bottom of the dust filter screen 35 is smoothly pulled out from the inside of the guide rail 31, so that the entire dust filter screen 35 can be completely pulled out;

[0035] When the dust filter screen 35 needs to be reinstalled, the operation process is also simple and clear. Only need to accurately insert the slide plate 34 on the dust filter screen 35 into the inside of the guide rail 31, and then loosen the non-slip push plate 337. At this time, the limiting spring 333 in the contracted state will quickly reset, pushing the movable block 334 to slide inside the sliding groove 331. During the sliding process of the movable block 334 pushed by the limiting spring 333, the limiting pin 335 at the end of the movable block 334 will be accurately inserted into the clamping groove 332. Through the reinsertion and clamping of the limiting pin 335 and the clamping groove 332, the dust filter screen 35 can be stably installed between the inside of the guide rail 31 outside the heat dissipation window 2, ensuring that the dust filter screen 35 is installed firmly and accurately positioned;

[0036] It is worth mentioning that in the use process, when the internal computer case 1 needs to be deeply maintained and maintained, not only can the dust filter screen 35 be removed through the above-mentioned mode, but also the whole heat dissipation window 2 can be directly opened. This design provides sufficient operation space for the maintenance and maintenance work of the internal hardware of the computer case 1, facilitates the equipment maintenance work of the technical personnel, at the same time, the decorative cover plate 336 provided by the device can effectively shield the sliding groove 331 in the daily use process, avoid dust and other impurities from entering the sliding groove 331 to affect the normal operation of the mechanism, and improve the overall appearance of the computer case 1 from the appearance, so that the computer case 1 meets the functional requirements while having good visual effect.
