Description

The computer housing turbine type is filtered dust guard

Technical field

The utility model relates to a kind of computer dust guard, and particularly a kind of computer housing turbine type is filtered dust guard, is particularly suited for relatively poor host computer of relative environment and power supply and carries out effectively dustproof and maintenance.

Background technology

Along with the application of computer with popularize, computer becomes more rich and varied and handy at people's live and work, numerous intensive electron devices in the computer housing, the heat that produces during its work is if untimely draining caused very big influence sometimes, directly burns electronic component and influences serviceable life of computer.For the serviceable life that how to prolong computer, people have made various effort, and one is exactly the fan that the air draft cooling is installed in casing, and it two is exactly to make the computer housing better tightness, prevents that harmful dust and steam from entering in the casing in order to avoid corrode electronic component.Because computer housing is not an obturator, the electromagnetic component in the cabinet also can adsorb dust simultaneously, causes dust in air to enter cabinet from the slit of cabinet, and electronic component is caused bad influence.Computer housing dust prevention on the market at present only limits to one deck Air Filter, and its dirt exclusion capabilities deficiency does not reach the dustproof effect of effective heat radiation.

Summary of the invention

Deficiency at above-mentioned computer housing dirt exclusion capabilities; the utility model provides a kind of computer housing turbine type to filter dust guard; it utilizes blower fan that outside air is imported in the cabinet, process multi-filtering when air enters cabinet, thus reach the optimum efficiency that purifies air, protects computer.

Technical solution adopted in the utility model:

A kind of computer housing filters dust guard, comprise cabinet side board, air exhauster, loam cake, lower cover and housing, loam cake and lower cover are by the fixing formation of screw housing, housing is fixed on the cabinet side board that air exhauster is housed, it is characterized in that in housing, being provided with air duct, be provided with air intake vent at the loam cake periphery, be respectively equipped with central circular groove and inside and outside two annular grooves at lower cover; The outer groove outside is connected with air intake vent, and outer groove is inboard to be connected with the inner groove outside, and the inner groove inboard is connected with central circular groove by the center air passage at housing middle part; In central circular groove and inside and outside annular groove, be filled with the air filtration body respectively.

The shape and size of air filtration body are corresponding with the shape and size of central circular groove and inside and outside annular groove in central authorities' circular groove, the inside and outside annular groove; The number that is filled with the annular groove of air filtration body is one or more, and one or two filtration housing that is filled with the air filtration body can be set on cabinet side board.

Described air filtration body is plastic sponge or vegetable fibre filter cotton.

During exhausting, air enters from air intake vent and enters along the air duct between inside and outside annular groove after filtering bodies in outer groove is filtered, the filtering bodies that enters in the central circular groove from the center air passage at housing middle part again after filtering bodies in inner groove is filtered is filtered, enter at last in the cabinet through purifying air behind the triple filter, prevent the erosion of dust effectively electronic component in the cabinet.This structure is filtered housing ring periphery and is provided with air intake vent, under fan draft effect, the air that enters in the cabinet produces malleation, discharge from casing exhausr port or slot outside the casing through the air of cooling electronic components in the casing, this fan fan blade rotates and air-flow flows like the turbo driving mode in housing.

This multi-filtering dust guard also is suitable for the power supply cabinet.

The beneficial effects of the utility model: compare with dust guard in the past; this dust guard is taked triple sponge filtrations; after the segmentation of the filtration sponge of the different densityes from the periphery to the central part is filtered successively; purified the air that enters in the computer housing effectively; guarantee that electronic component is avoided effect of dust in the cabinet; having improved the unreachable dustproof effect of conventional dust guard pollution abatement equipment greatly. this dust guard mounting or dismounting simultaneously are convenient, are convenient to cleaning, the replacing of air filtration body.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is unkitted air filtration body synoptic diagram for the utility model housing;

Fig. 3 is the utility model dust guard exploded view.

Among the figure, 1. housing, 2. loam cake, 3. lower cover, 4. air intake vent, 5. center air passage, 6. air exhauster, 7. central filtering bodies, 8. the outer shroud filtering bodies, 9. in ring filtering bodies, 10. cabinet side board, 11. screw holes, 12. central circular grooves, 13. outer grooves, 14. inner grooves.

Embodiment

The contrast accompanying drawing illustrates its structure.

In Fig. 1～3, loam cake 2 and lower cover 3 are by screw hole 11 fixing formation housings 1, in lower cover central authorities circular groove 12, place central filtering bodies 7, in outer groove 13, place outer shroud filtering bodies 8, ring filtering bodies 9 in placing in inner groove 14, the housing that the air filtration body is housed is fixed on the cabinet side board 10 that air exhauster 6 is installed.During exhausting, the air exhauster running, the air intake vent 4 that extraneous air sees through the loam cake periphery enters outer shroud filtering bodies 8, after the filtration, entering interior the ring in the filtration 9 along the air duct between inside and outside annular groove filters, the central filtering bodies 7 that enters in the central circular groove of center air passage 5 in the middle of the housing is filtered again, and the air behind triple filter just enters in the cabinet at last, prevents from effectively that harmful dust from entering in the cabinet electronic component in the cabinet is caused harmful effect.
