Abstract
The utility model provides a dustproof structure for a projector. The dustproof structure comprises an air inlet, a filter screen, an upper cover and a lower cover, wherein the upper cover and the lower cover are assembled together, the air inlet is arranged above the upper cover, the filter screen is arranged on the back of the air inlet, the air inlet is fixed above the upper cover through a crew, the upper cover and the lower cover are assembled together through a clip or screw, and a cavity is formed by being surrounded by the upper cover, the lower cover and the air inlet. The dustproof structure has the advantages that the dustproof effect is good, and the filter screen can be conveniently cleaned and replaced.
Description
Technical field
The utility model relates to dustproof construction, relates in particular to a kind of dustproof construction that is used for projector.
Background technology
At present, no matter be LCD (LCDs) projector, or DLP (digital light processing) projector, to the requirement of environment for use all than higher, particularly optical component is subjected to the influence of particulate in the air very big, and this just requires projector to have the good dust-proof performance.Wherein, the common dustproof construction that is used for projector is that the air intake opening in projector adds material for air purification, to reach dustproof purpose.In order not influence the radiating effect of projector, and be subjected to the restriction of projector's physical dimension, have only to increase the air intake opening area as much as possible, to improve dustproof effect.So the environment for use of the common dustproof construction that is used for projector is subjected to certain restriction, only under environment preferably, when using in the air-conditioned room, air inlet eloquence is not easy blocked, under rugged surroundings, such as areas such as open air, outlying villages and small towns, sandstorms, the common dustproof construction that is used for projector can be very fast blocked, cause the damage of projector, and need take off video camera and just can clean and change screen pack, use inconvenience.
The utility model content
The technical problems to be solved in the utility model provides a kind of dustproof construction that is used for projector, is intended to solve the dustproof construction that is used for projector common in the prior art and stops up easily, and screen pack cleans and change inconvenience.
In order to solve the above-mentioned technical matters that is used for the dustproof construction of projector, the utility model adopts following technical scheme:
A kind of dustproof construction that is used for projector comprises shutter, screen pack, loam cake and lower cover, the assembling of described loam cake and lower cover together, shutter be arranged on loam cake above.
Further, described screen pack is arranged on the back side of shutter,
Further again, described shutter by screw retention on loam cake.
Further, described loam cake and lower cover are assembled together by buckle or screw.
Further again, described screen pack is by the back side of glue at shutter.
Further, described filter network card is at the back side of shutter.
Further again, described loam cake, lower cover and shutter surround into a cavity.
The dustproof construction that is used for projector of the present utility model has dustproof preferably effect, and screen pack can clean and change easily.
Description of drawings
Fig. 1 is the structural representation of the dustproof construction that is used for projector of the utility model embodiment.
Fig. 2 is the dustproof construction assembled construction synoptic diagram that is used for projector of the utility model embodiment.
Fig. 3 is the structural representation that the dustproof construction that is used for projector of the utility model embodiment is applied to projector.
Embodiment
The dustproof construction that is used for projector of this embodiment as shown in Figure 1, comprises shutter 2, screen pack 3, loam cake 4, lower cover 5.Loam cake 4 and lower cover 5 are assembled together by buckle or screw, and screen pack 3 also can directly be stuck in the back side of shutter 2 by the back side of glue at shutter 2, shutter 2 by screw retention on loam cake 4.Loam cake 4, lower cover 5 and shutter constitute a cavity 6.As shown in Figure 2, shutter 2 assembles by screw 1, unclamps screw 1 and can take out screen pack and clean and change.
The dustproof construction that is used for projector of this embodiment is applied to projector, as shown in Figure 3, utilize the lifting screw 8 of projector that dustproof construction 7 is fixed in the projector 10, when projector 10 opens, extraneous air passes through the shutter 2 of dust seal structure 7 earlier, after purifying through screen pack 3, along the cavity of dustproof construction, the air inlet window 9 by projector enters projector 10.
The dustproof construction that is used for projector of this embodiment can be used as the apolegamy annex of projector, uses under rugged surroundings, and dustproof effect is obvious.Because screen pack is away from the air inlet window of video camera,, can reduces video camera inside and be polluted so clean or when changing screen pack, can not cause dust to drop to the video camera the inside.When projector's furred ceiling is installed, adopt the dustproof construction that is used for projector of this embodiment, not needing to take off video camera is capable of washing or the replacing screen pack, more convenient to use.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
