Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] As Figures 1 to 3 shown, a dust-proof device for a computer in an embodiment of the present utility model includes a dust-proof device body 1, a filter device 2, and a flow equalization assembly 3.

[0031] As Figures 1 to 3 shown, the dust-proof device body 1 includes a chassis 11. The front end of the chassis 11 is detachably installed with a front cover plate 12, so that it is convenient to disassemble and assemble between the front cover plate 12 and the chassis 11. A plurality of inlet fans 13 are installed on the side wall of the front cover plate 12 close to the chassis 11, and an outlet fan 16 is installed on the rear side wall plate of the chassis 11. The outside air is introduced into the chassis 11 through the inlet fans 13, and then the hot air in the chassis 11 is replaced and discharged through the outlet fan 16, so as to realize the heat dissipation inside the chassis 11.

[0032] As Figures 1 to 3 shown, a plurality of first air inlets 14 are formed in the front side wall of the front cover plate 12, so that the outside air enters through the first air inlets 14. The plurality of first air inlets 14 are arranged in an annular shape or the like. In order to make the appearance of the chassis look good after the first air inlets 14 are arranged, the first air inlets 14 can be arranged in different shapes, while ensuring that the air can enter the chassis and maintaining the beauty of the chassis appearance.

[0033] As Figure 3 shown, a plurality of second air inlets 15 are formed in the rear side wall of the front cover plate 12, and the air inlets of the plurality of air inlet fans 13 are respectively installed on the plurality of second air inlets 15, so that the second air inlets 15 can introduce air into the air inlet fans 13.

[0034] As Figure 2 and Figure 3 shown, a plurality of air outlets 17 are formed in the rear side wall plate of the chassis 11, and the air outlet of the air outlet fan 16 is installed on the plurality of air outlets 17, so that the air outlet fan 16 discharges the hot air in the chassis 11 through the air outlets 17.

[0035] As Figures 2 to 4 shown, the filtering device 2 includes a mounting shell 21, and the mounting shell 21 is detachably mounted in the front cover plate 12, so that it is convenient to disassemble when the mounting shell 21 is mounted in the front cover plate 12, thereby facilitating the maintenance and cleaning of the components mounted on the mounting shell 21. A first filter screen 22 and a second filter screen 23 are installed in the mounting shell 21. The first filter screen 22 and the second filter screen 23 are used to filter the air entering the chassis 11 to intercept the dust in the air. At the same time, the pore size of the filter screen on the first filter screen 22 is larger than the pore size of the filter screen on the second filter screen 23, so that the air is filtered multiple times by the first filter screen 22 and the second filter screen 23 to ensure that the dust in the air is filtered clean. The easy disassembly and assembly of the mounting shell 21 makes it convenient to disassemble and assemble the first filter screen 22 and the second filter screen 23, thereby facilitating the cleaning of the dust and other impurities intercepted on the first filter screen 22 and the second filter screen 23.

[0036] As Figure 2 and Figure 3 shown, the first filter screen 22 is arranged on the side close to the first air inlet 14, and the second filter screen 23 is arranged on the side close to the second air inlet 15, so that when the air enters, it is first filtered by the first filter screen 22 and then filtered by the second filter screen 23.

[0037] As Figure 4As shown, an installation groove 24 is formed inside the front cover plate 12, and the installation shell 21 is installed in the installation groove 24 in a sliding connection manner. The sliding connection makes it convenient to disassemble and assemble the installation shell 21 in the installation groove 24, and thus facilitates the cleaning of the first filter screen 22 and the second filter screen 23.

[0038] As Figure 3 shown, both the first air inlet 14 and the second air inlet 15 are connected to the installation groove 24, so that the outside air can enter through the first air inlet 14 and can be filtered by the first filter screen 22 and the second filter screen 23, and the filtered air is transported into the air inlet fan 13 through the second air inlet 15. A limiting groove 26 is formed on one side of the installation groove 24.

[0039] As Figure 4 shown, a limiting plate 25 is fixedly connected to the side wall of the installation shell 21, the limiting groove 26 is sleeved inside the limiting plate 25, and a pair of fixing screws 27 are threadedly connected to the limiting plate 25 and the limiting groove 26. The limiting plate 25 can be fixed in the limiting groove 26 through the fixing screws 27, so that the installation shell 21 is stable when installed in the installation groove 24; at the same time, the fixing screws 27 can be disassembled and assembled by rotation, so that the installation and disassembly of the installation shell 21 are convenient.

[0040] As Figure 2 and Figure 3 shown, the flow equalizing component 3 includes a flow equalizing box 31. There are multiple flow equalizing boxes 31, and the multiple flow equalizing boxes 31 are respectively installed on the air outlet of multiple air inlet fans 13. In order to make the air introduced into the chassis 11 by the air inlet fans 13 evenly distributed, so as to improve the replacement efficiency of the hot air in the chassis 11, by setting the flow equalizing box 31, the air introduced by the air inlet fans 13 is shunted. A plurality of flow equalizing holes 32 are formed on the side wall of the flow equalizing box 31 away from the air inlet fan 13. The air entering the flow equalizing box 31 is shunted through the plurality of flow equalizing holes 32, so that it is evenly distributed in the chassis 11.

[0041] As Figure 5 shown, the plurality of flow equalizing holes 32 are arranged in a ring shape, and a plurality of rings are formed by the plurality of flow equalizing holes 32, which improves the range of air dispersion by the flow equalizing holes 32.

[0042] As Figure 5 shown, the flow equalizing holes 32 are inclined in a manner from the center of the flow equalizing box 31 to the outside. The inclination degrees of the flow equalizing holes 32 on the same ring are the same, and the inclination degrees of the flow equalizing holes 32 on different rings are set to gradually increase from the center of the flow equalizing box 31 to both sides. The inclined arrangement of the flow equalizing holes 32 enables the flow equalizing holes 32 to disperse the air in all directions, so that the air is evenly distributed in the chassis 11.

[0043] During use, when the computer is running, the intake fan 13 and the exhaust fan 16 will automatically operate. The outside air enters the chassis 11 through the first air inlet 14. When entering, the air will first pass through the first filter screen 22 and the second filter screen 23 for filtering to intercept the dust in the air. The filtered air enters the intake fan 13 through the second air inlet 15. The intake fan 13 pressurizes the air and transports it into the flow equalizing box 31, and then the air is divided through the flow equalizing holes 32 and transported into the chassis 11, making the air evenly distributed in the chassis 11. When the air flows in the chassis 11, it can transport the hot air in the chassis 11 into the exhaust fan 16, and finally the exhaust fan 16 discharges the hot air through the air outlet 17, realizing the heat dissipation in the chassis 11. When the first filter screen 22 and the second filter screen 23 need to be cleaned, remove the fixing screws 27 by rotation, and then pull out the mounting shell 21 from the front cover plate 12 by sliding, and then it is convenient to clean the first filter screen 22 and the second filter screen 23. After cleaning, it can be reinstalled by sliding.
