Problems solved by technology

[0004] However, at present, dust-proof nets or dust-proof sponges are used on the chassis to filter the air entering the chassis, and the filtration accuracy cannot be adjusted during use, that is, the dust-proof performance cannot be adjusted, so the ventilation and dust-proof performance of the chassis cannot be weighed according to actual needs Trade-offs, lack of applicability

Embodiment 1

[0032] In this embodiment, the adjustable filter layer adopts the sponge layer 8. The sponge layer 8 is a porous structure. After being compressed, the pore diameter of the internal pores will be reduced, thereby improving the filtering accuracy of dust. When the filtration accuracy needs to be improved, the adjusting nut 6 is screwed, and the support net 1 on the front side is pushed back, such as figure 2 As shown, the spring 7 is compressed, and the sponge layer 8 can be compressed; when the filtration accuracy needs to be reduced, the adjusting nut 6 is reversely screwed, and the support net 1 on the front side is pushed forward by the elastic force of the spring 7, and the Due to the elastic force of the sponge layer 8 itself, the sponge layer 8 can be gradually released from the compressed state.

[0033] When cleaning, press the two support nets 1 to compress the sponge layer 8, and then release the elastic force of the spring 7 to not only restore the sponge layer 8 f...

Embodiment 2

[0035] The difference between this embodiment and embodiment 1 is that the adjustable filter layer adopts the PP melt-blown layer 9 .

[0036] The PP melt-blown layer 9 is also a porous structure. The dust filtration accuracy can be adjusted by compressing and releasing the PP melt-blown layer 9. However, the sponge layer 8 has strong elasticity and can recover by itself when released, so it does not need to be connected with the support. The net 1 is fixed, but the elasticity of the PP melt blown layer 9 is not strong, and it is difficult to recover through its own elasticity when it is released. Therefore, the PP melt blown layer 9 and the support net 1 need to be fixed, and the PP melt blown layer 9 is driven by the support net 1 when released. Resume from a compressed state.

[0037]For this reason, on the inner surface of the support net 1, the hook surface mesh adhesive chain 10 is attached and fixed, and the hook surface shape of the hook surface mesh adhesive chain 10 ...

Abstract

The invention discloses a computer case dustproof device, and relates to the technical field of computer case dust prevention. The device comprises two supporting nets which correspond to each other in a front-back parallel mode; an adjustable filtering layer is clamped between the two supporting nets; the periphery of the rear end of the rear supporting net is correspondingly and hermetically connected with the periphery of the front end of the air inlet net plate of the case; a net-shaped sealing plate is arranged on the rear side of the air inlet net plate in parallel; meshes of the net-shaped sealing plate and meshes of the air inlet net plate are arranged in a staggered mode; guiding columns are vertically fixed to the periphery of the air inlet net plate in a penetrating mode; the net-shaped sealing plate and the supporting net are slidably connected to the guide columns in a sleeving manner; an adjusting bolt vertically penetrates through the middle part of the air inlet screen plate; the adjusting bolt is rotationally connected with the air inlet screen plate; the front portion of the adjusting bolt penetrates through the supporting net and the adjustable filtering layer, and the rear portion of the adjusting bolt penetrates through the net-shaped sealing plate. The computer case has the beneficial effects that the dust filtering precision can be adjusted, so that the ventilation and dustproof performance of the case can be adjusted, and the computer case can be conveniently cleaned.

Description

technical field [0001] The invention relates to the technical field of computer case dustproofing. Background technique [0002] In order to ensure the heat dissipation of computer host accessories, ventilation holes need to be provided on the chassis, but at the same time, external dust will also enter the interior of the chassis with the air, and gradually accumulate inside the chassis, causing adverse effects on heat dissipation, so a good chassis needs Considering both ventilation and dustproofing, how to strike a proper balance between ventilation and dustproofing is the main point of chassis design. [0003] However, due to the different use environments of the chassis, in many cases it is impossible to balance ventilation and dust protection. At this time, it is necessary to make a trade-off between ventilation and dust protection according to the use environment. For example, in a dusty environment, it is necessary to give priority to ensuring good dust protection. ...
