Problems solved by technology

Because the computer case is not a closed body, and the electronic components in the case will also absorb dust, causing the dust in the air to enter the case from the gaps in the case, causing adverse effects on the electronic components
At present, the dust-proof measures for computer cases on the market are limited to a layer of dust-proof net, which has insufficient dust-proof ability and has not achieved effective heat dissipation and dust-proof effect.

Embodiment Construction

[0016] Referring to the accompanying drawings, illustrate its structure.

[0017] exist Figure 1~3 Among them, the upper cover 2 and the lower cover 3 are fixed through the screw holes 11 to form the housing 1, the central filter body 7 is placed in the central circular groove 12 of the lower cover, the outer ring filter body 8 is placed in the outer ring groove 13, and the inner ring groove 14 The inner ring filter body 9 is placed inside, and the housing with the air filter body is fixed on the cabinet side plate 10 on which the exhaust fan 6 is installed, and the air inlet of the exhaust fan is facing the position of the central circular groove. When the air is exhausted, the exhaust fan is running, and the external air enters the outer ring filter body 8 through the air inlet 4 around the upper cover. The central air channel 5 enters the central filter body 7 in the central circular groove for filtration, and the purified air after triple filtering finally enters the cha...

Abstract

The invention relates to a filtering dustproof device of a computer chassis, comprising a chassis side plate, an exhaust fan, a shell, an upper cover and a lower cover. The upper cover and the lower cover are fixed by screws to form a shell; the shell is internally provided with an air passage; air inlet holes are arranged on the periphery of the upper cover; the lower cover is respectively provided with a central circular groove, an internal annular groove and an external annular groove; and the central circular groove, the internal annular groove and the external annular groove are all internally provided with air filtering sponges. By adopting trebling air filtering combined with the exhaust fan turbo-type air exhaust and supply, the invention effectively solves the problem of air purification in the computer chassis so as to prevent harmful dust from corroding computer electronic elements and prolong the service life of the computer. Besides, the structure is convenient to assemble and disassemble and is convenient for the cleaning and changing of filtering sponge.

Description

technical field [0001] The invention relates to a dust-proof device for a computer, in particular to a multi-filter dust-proof device for a computer case, which is especially suitable for effective dust-proof and maintenance of a computer mainframe and a power supply with a relatively poor environment. Background technique [0002] With the application and popularization of computers, computers have become more colorful and handy in people's life and work. There are many dense electronic devices in the computer case. If the heat generated during work is not discharged in time, it will sometimes cause a great impact. Directly burn electronic components and affect the service life of the computer. For how to prolong the service life of the computer, people have made various efforts, one is exactly to install the fan of exhaust air cooling in the box body, and the other is to make the computer box better sealed, prevent harmful dust and water vapor from entering the box body so...
