Embodiment
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model is clearly and completely described.
Based on the embodiment in the utility model, what those of ordinary skill in the art were obtained without creative efforts
Every other embodiment, shall fall within the protection scope of the present invention.
As shown in Figure 1 to Figure 3, the projecting apparatus of the utility model, including casing 1, radiator window 2, multiple cooling stands 7 and with
The corresponding dust guard 3 of 7 quantity of cooling stand；Radiator window 2 is opened on casing 1, and multiple cooling stands 7 are horizontal or vertical are arranged at
In the window of radiator window 2, multiple dust guards 3 are sheathed on cooling stand 7 respectively, dust guard 3 is rotated on cooling stand 7,
Open or block 2 window of radiator window.When using a projector, rotate dust guard 3, make 2 window of radiator window open, projecting apparatus into
Row heat dissipation；When projecting apparatus need not radiate, dust guard 3 is rotated, edge fold between adjacent dust guard 3, closes 2 window of radiator window
Close.The setting ensure that projecting apparatus when not in use dust-proof while simple in structure, and manufacture cost is low.
To realize the quick heat radiating of projecting apparatus, there is provided micro air pump 4 and ventilation shaft 5；Ventilation shaft 5 is laid in screening dirt
In the both sides plate face of plate 3, some air outlets, air inlet and the micro air pump 4 of ventilation shaft 5 are opened up on the tube wall of ventilation shaft 5
Air outlet unicom.When the projector is in use, micro air pump 4 is started, micro air pump 4 blasts gas in ventilation shaft 5.Due to
Ventilation shaft 5 is laid on dust guard 3, and some air outlets have been opened up on the tube wall of ventilation shaft 5, therefore, the gas blasted
