Abstract
The present utility model discloses a novel projector dustproof device. In the device, a fixing support is arranged on the position of a projector cabinet air opening, a magnet is arranged on the fixing support, an iron sheet fitted with the magnet of the fixing support is arranged on a fan cover, the fixing support is connected with the projector cabinet, a cross beam for arranging the magnet is arranged on the middle part; and the fan cover is lattice-shaped, and each ventilating sheet of the fan cover is arranged in an inclined way. In the device, the magnet is used for absorbing the fixing support with the fan cover, it is simple and convenient for disassembling and assembling the fan cover when removing dust, and the projector dustproof device adopting the structure is low in costs and simple to manufacture.
Description
Technical field
The utility model relates to a kind of projector utility appliance, relates in particular to the New Projection Display dust guard.
Background technology
In the existing projector dust preventing device, generally adopt screw that dust cover is fixed in the projector.Adopt the dust guard of this mode, when dust out, the dust guard dismounting is inconvenient; And screw retention is prone to get rusty, and makes dust guard be difficult for pulling down, and the inner dust of projector can not in time be removed; Cause heat radiation bad easily, influence liquid crystal life-span and image quality.There also have the part projector dust preventing device to adopt buckle-type to connect to be fixing, and in this method, dust guard needs independent die sinking, and producing cost is higher.
Summary of the invention
The purpose of the utility model is to overcome the problems referred to above that existing projector dust preventing device exists, and the New Projection Display dust guard is provided.The utility model easy installation and removal, and production cost is lower.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
The New Projection Display dust guard comprises fan housing, it is characterized in that: projector's cabinet tuyere position is provided with fixed support; Said fan housing and fixed support magnetic are connected.
Said fixed support is provided with magnet, fan housing be provided with fixed support on the iron plate that cooperates of magnet.
Said fixed support and projector's cabinet are connected as a single entity, and the center is provided with the crossbeam that magnet is installed.
Said fan housing is lattice-shaped, and each cowl flap on it is in tilted layout.
The advantage of the utility model is:
The utility model utilizes magnet that fixed support and fan housing are attached together, and during dust out, dismounting and installation fan housing are simple and convenient, and adopt the New Projection Display dust guard cost of this structure low, make simple.
