Preferably, described case is cuboid, forms described vent passages between the two sides that described case is relative, and the four additional side of described case constitutes the housing around described vent passages, and described Air Filter is installed on described housing.
Preferably, described case offering and described Air Filter opening one to one, described Air Filter is inserted in described case by described opening.
Preferably, the chute it guided when described Air Filter inserts described case is offered in described case.
Preferably, the external port of described vent passages is made up of the multiple through holes being opened on described case；The inner port of described vent passages is formed by the rectangular opening being opened on described case.
Preferably, the plurality of described through hole is matrix form arrangement.
Preferably, the aperture of described through hole is more than the aperture in maximum filtering hole.
Preferably, by described external port to described inner port direction, on each described Air Filter, the aperture of filtering holes is gradually reduced.
Preferably, described Air Filter includes having the main part of some described filtering holes, be surrounded on described main part periphery and support the framework of described main part.
Preferably, described case is outside equipped with the adhesive piece at the air inlet being fixed in described power information switch.
Owing to technique scheme is used, this utility model compared with prior art has the advantage that the dust entering switch can be filtered by dust cover of the present utility model effectively, thus avoid the dust accretions impact on fan at fan, it also avoid dust and enter switch and impact on wherein parts.It is convenient to use, time saving and energy saving, can be greatly prolonged the service life of switch fan by it, is greatly improved the stability of switch work, extends the length of service of switch.

Detailed description of the invention
This utility model is further described by the embodiment shown in below in conjunction with the accompanying drawings.
Embodiment one: as shown in accompanying drawing 1 to accompanying drawing 6, the power information switch dust cover at a kind of air inlet being arranged at power information switch, including case 1 and multilamellar Air Filter 2.
Case 1, in cuboid, uses transparent acrylic to make.Two sides being oppositely arranged of case 1, one of them offers multiple through hole 3 arranged in matrix form, rectangular opening 4 is then offered on another, thus, vent passages is defined between the side that the two is relative, in matrix form, the through hole 3 of arrangement is formed for the external port of vent passages, and rectangular opening 4 forms the inner port of vent passages.The four additional side of case 1 constitutes the housing around vent passages.
Multilamellar Air Filter 2 is arranged in case 1, and every layer of Air Filter 2 all can completely cover vent passages cross section.Air Filter 2 includes having the main part 5 of some filtering holes, be surrounded on the framework 6 of main part 5 periphery supportive body part 5.Multilamellar Air Filter 2 is arranged successively along by the direction of the inside port of vent passages external port, every layer of Air Filter 2 is toward being respectively provided with the filtering holes that aperture is identical, and the aperture of filtering holes is different on multilamellar Air Filter 2, by the inside port direction of the external port of vent passages, on each Air Filter 2, the aperture of filtering holes is gradually reduced, and on case 1, the aperture of through hole 3 is more than the aperture in maximum filtering hole.In the present embodiment, it is provided with two-layer Air Filter 2.
Owing to Air Filter 2 needs completely to cover vent passages cross section, therefore Air Filter 2 is arranged on the housing of vent passages.Housing is made up of four sides of case 1, and the side, side of the case 1 constituting housing offers and Air Filter 2 opening 7 one to one, and opening 7 sidepiece also has attacker position 8, thus Air Filter 2 can be inserted in case 1 by corresponding opening 7.And the inner side of housing, then corresponding opening 7 is provided with the chute 9 guided it when Air Filter 2 inserts case 1.When Air Filter 2 inserts and puts in place, chute 9 also acts as restriction effect to the position of Air Filter 2, places Air Filter 2 and offsets so that it is can cover the cross section of vent passages all the time.
This dust cover is arranged at the air inlet of power information switch fan.The both sides of the inner port of, vent passages outer at case 1, are provided with the adhesive piece 10 at the air inlet being fixed in power information switch.After dust cover installs, the external port of vent passages is connected with the external world, and the inner port of vent passages is connected with air inlet.When the fan work of switch, air is entered in case 1 by the external port of vent passages, the i.e. through hole 3 of matrix form arrangement, sequentially passes through the filtration of multistorey strainer mesh, and finally by the inner port of vent passages, i.e. rectangular opening 4 on case 1 enters air inlet.Such that the most dusts in air can be intercepted outside switch, it is to avoid the dust accretions impact on fan at fan, it also avoid dust and enter switch and impact on wherein parts.In use for some time, Air Filter 2 can be extracted out by opening 7, clears up or changes.This dust cover is convenient to use, time saving and energy saving, can be greatly prolonged the service life of switch fan by it, is greatly improved the stability of switch work, extends the length of service of switch.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this.All equivalence changes made according to this utility model spirit or modification, all should contain within protection domain of the present utility model.
