Description

电脑机箱过滤防尘装置  Computer case filter dustproof device
技术领域 Technical field
本发明涉及一种电脑用防尘装置, 特别是一种电脑机箱多重过滤防尘装置, 尤其适用于相对环境较差的电脑主机及电源进行有效的防尘和维护。  The invention relates to a dustproof device for a computer, in particular to a multi-filter dustproof device for a computer case, which is particularly suitable for effective dustproofing and maintenance of a computer host and a power source which are relatively poor in environment.
背景技术 Background technique
随着电脑的应用和普及, 电脑使人们的生活和工作变得更加丰富多采和得心 应手。 电脑机箱内有众多的密集电子器件, 它们工作时产生的热量若不及时排走 有时会造成很大的损害, 如直接烧毁电子元件而影响电脑的使用寿命。对于如何 延长电脑的使用寿命, 人们做出了各种的努力, 其一就是在机箱箱体中安排排风 降温的风扇, 其二是使用密封性更好的电脑机箱, 防止有害灰尘和水汽进入箱体 内使电子元件避免受到侵蚀。 由于电脑机箱不是密闭体, 空气中的灰尘很容易就 从机箱的缝隙处进入机箱,吸附在电子元件上,从而对电子元件造成不良的影响。 目前, 市面上的电脑机箱防尘措施仅限于一层防尘网, 其防尘能力不足, 并未达 到有效的散热防尘效果。  With the application and popularity of computers, computers have made people's lives and work more colorful and handy. There are a large number of dense electronic devices in the computer case. If the heat generated during operation is not removed in time, it will cause great damage, such as directly burning electronic components and affecting the service life of the computer. People have made various efforts to extend the life of the computer. One is to arrange a fan for cooling in the chassis, and the other is to use a computer case with better sealing to prevent harmful dust and moisture from entering. The electronics are protected from erosion in the cabinet. Since the computer case is not a closed body, dust in the air can easily enter the chassis from the gap of the chassis and be adsorbed on the electronic components, thereby adversely affecting the electronic components. At present, the dustproof measures for computer chassis in the market are limited to one layer of air filter. The dustproof capacity is insufficient, and the effective heat dissipation and dustproof effect is not achieved.
发明内容 Summary of the invention
针对上述电脑机箱防尘能力的不足, 本发明提供一种电脑机箱过滤防尘装 置, 其利用风机将外界空气导入机箱内, 空气进入机箱时经过多重过滤, 从而达 到净化空气、 保护电脑的效果。  In view of the insufficiency of the dustproof capability of the computer case, the present invention provides a dust filter device for filtering a computer case, which uses a fan to introduce outside air into the chassis, and multiple filters are used when the air enters the chassis, thereby achieving the effect of purifying air and protecting the computer.
为达到上述发明目的, 本发明采用如下技术方案: 一种电脑机箱过滤防尘装 置, 包括机箱侧板、 抽风机、 上盖、 下盖和过滤壳体。 上盖和下盖通过螺丝固定 构成过滤壳体, 壳体固定在装有抽风机的机箱侧板上。在过滤壳体内设有空气通 道, 在上盖周边设有入风口, 在下盖中分别设有中央圆槽、 内环槽和外环槽。 外 环槽外侧与入风口相连通, 外环槽的内侧与内环槽的外侧相连通, 内环槽的内侧 通过过滤壳体中部的中央空气通道与中央圆槽相连通。在中央圆槽、 内环槽和外 环槽内分别装填有空气过滤体。  In order to achieve the above object, the present invention adopts the following technical solutions: A computer chassis filtering dustproof device includes a chassis side panel, an exhaust fan, an upper cover, a lower cover, and a filter housing. The upper cover and the lower cover are fixed by screws to form a filter housing, and the housing is fixed to the side panel of the chassis equipped with the exhaust fan. An air passage is arranged in the filter housing, and an air inlet is arranged around the upper cover, and a central circular groove, an inner ring groove and an outer ring groove are respectively arranged in the lower cover. The outer side of the outer ring groove communicates with the air inlet, and the inner side of the outer ring groove communicates with the outer side of the inner ring groove. The inner side of the inner ring groove communicates with the central circular groove through a central air passage in the middle of the filter housing. Air filter bodies are installed in the central circular groove, the inner ring groove and the outer ring groove, respectively.
所述的抽风机设在机箱侧板内面, 抽风机进风口正对于中央圆槽位置。 中央圆槽、 内环槽和外环槽内的空气过滤体的形状和尺寸与中央圆槽及内、 外环槽的形状和尺寸相对应。 装填有空气过滤体的环槽的数目为一个或一个以 上。 在机箱侧板上可设置一个或两个装填有空气过滤体的过滤壳体。 The exhaust fan is disposed on the inner surface of the side panel of the chassis, and the air inlet of the exhaust fan is positioned at the central circular groove. The shape and size of the air filter body in the central circular groove, the inner ring groove and the outer ring groove correspond to the shape and size of the central circular groove and the inner and outer annular grooves. The number of ring grooves filled with the air filter body is one or more. One or two filter housings filled with air filters can be placed on the side panels of the chassis.
所述的空气过滤体为塑料海绵或植物纤维过滤棉。 壳体的上盖和下盖分别一 体注塑成型。  The air filter body is a plastic sponge or a plant fiber filter cotton. The upper and lower covers of the housing are integrally injection molded.
本发明的过滤防尘装置适用于电源机箱或需通风降温除尘的其他电器机箱。 抽风时, 空气从入风口进入, 经外环槽内的空气过滤体过滤后沿内外环槽间 的空气通道进入,经内环槽内的空气过滤体过滤后再从过滤壳体中部的中央空气 通道进入中央圆槽内的过滤体进行过滤。经过三重过滤后的净化空气最后进入机 箱内, 有效地防止灰尘对机箱内电子元件的侵蚀。本结构过滤壳体周边设有入风 口, 在风扇抽力作用下, 机箱内的空气产生正压, 箱体内经冷却电子元件的空气 从箱体排气口或隙缝中排出箱体外。这种风扇叶转动及气流在过滤壳体内流动似 涡轮运转方式, 气流流动顺畅, 空气过滤除尘效果好。  The filtering dustproof device of the invention is suitable for a power supply chassis or other electrical equipment chassis that requires ventilation to cool and remove dust. When the air is exhausted, the air enters from the air inlet, is filtered by the air filter body in the outer ring groove, enters along the air passage between the inner and outer ring grooves, is filtered by the air filter body in the inner ring groove, and then is filtered from the central air in the middle of the filter housing. The channel enters the filter in the central circular tank for filtration. The triple-filtered purified air finally enters the cabinet, effectively preventing dust from eroding the electronic components inside the chassis. The air filter is arranged around the filter casing. Under the action of the fan, the air in the casing generates a positive pressure, and the air in the casing through the cooling electronic component is discharged from the casing exhaust port or the slot. The fan blade rotates and the airflow flows in the filter housing like a turbine operation mode, the airflow is smooth, and the air filter dust removal effect is good.
本发明的有益效果是: 与以往的防尘装置相比, 本防尘装置采取三重海绵过 滤结构, 依次从外围到中央部位的不同致密密度的过滤海绵的分段过滤后, 有效 地净化了进入机箱内的空气, 确保机箱内电子元件免受灰尘的影响, 大大提高了 常规防尘设备所不能达到的防尘效果, 从而提高了电子元件的使用寿命。 同时, 本防尘装置装拆方便, 便于空气过滤体的清洗和更换。 附图说明  The invention has the beneficial effects that: compared with the conventional dustproof device, the dustproof device adopts a triple sponge filtering structure, and sequentially filters the different dense density filter sponges from the periphery to the central portion to effectively purify the entry. The air inside the chassis ensures that the electronic components inside the chassis are protected from dust, which greatly improves the dustproof effect that can not be achieved by conventional dustproof devices, thereby improving the service life of electronic components. At the same time, the dustproof device is convenient to assemble and disassemble, and is convenient for cleaning and replacing the air filter body. DRAWINGS

The periphery of the upper cover 2 is provided with an air inlet 4, and the lower cover is provided with a central circular groove 12, an outer ring groove 13 and an inner ring groove 14, respectively. The central filter body 7 is placed in the central circular groove 12, the outer ring filter body 8 is disposed in the outer ring groove 13, and the inner ring filter body 9 is disposed in the inner ring groove 14. The filter housing 1 equipped with an air filter is fixed to the chassis side panel 10 on which the exhaust fan 6 is mounted, and the air inlet of the exhaust fan 6 is positioned at the center circular groove 12.
抽风时, 抽风机运转, 外部空气透过上盖 2周边的入风口 4进入外环过滤体 8。 经外环过滤体 8过滤后, 空气沿内环槽 14和外环槽 13之间的空气通道进入 内环过滤体 9中进行过滤。之后, 空气再从过滤壳体 1中间的中央空气通道 5进 入中央圆槽内 12的中央过滤体 7进行过滤。 经过三重过滤后的净化空气最后才 进入机箱内, 有效地防止有害灰尘进入机箱内对机箱内电子元件造成不良影响, 延长了电脑的使用寿命。  When the air is exhausted, the exhaust fan operates, and the outside air enters the outer ring filter body 8 through the air inlet 4 around the upper cover 2. After being filtered by the outer ring filter 8, air is introduced into the inner ring filter 9 through the air passage between the inner ring groove 14 and the outer ring groove 13 for filtration. Thereafter, the air is again filtered from the central air passage 5 in the middle of the filter housing 1 into the central filter body 7 in the central circular groove 12. The triple-filtered purified air finally enters the chassis, effectively preventing harmful dust from entering the chassis and adversely affecting the electronic components in the chassis, thereby prolonging the service life of the computer.
