The invention discloses a dustproof cooling cover for a color wheel and a light-gathering cavity of a projector. The dustproof cooling cover comprises a front shell, a rear shell, a cover board and a vortex fan, wherein a light through hole matched with the light-gathering cavity in shape is formed in the front shell; a round hole matched with the light-gathering cavity in shape is formed in the rear shell; the rear shell is arranged on a main body of a bare engine; the front shell is arranged on the rear shell; the cover board is arranged at the upper parts of the rear shell and the front shell; the vortex fan is arranged on the main body of the bare engine; and an air outlet of the vortex fan is connected to a corresponding air inlet of the rear shell. The rear shell, the front shell and the cover board form an air-tight cavity; and the color wheel component and the light-gathering cavity component are sealed in the air-tight cavity, so that dust can be effectively prevented; the color wheel component and the light-gathering cavity component can be protected; a light path system is prevented from being polluted; and meanwhile, the color wheel component and the light-gathering cavity component can be effectively cooled by the extra vortex fan.
Description
technical field [0001] The invention relates to a projector accessory, in particular to a color wheel of the projector and a dust-proof and heat-dissipating cover of a light-gathering cavity. Background technique [0002] At present, projectors, especially DLP projectors, are widely used, and the color wheel assembly and light collecting cavity assembly are important components of the projector. [0003] Since the projector usually uses a fan to force the air in to improve the heat dissipation efficiency, it is easy to bring the dust in the outside air into the projector; the color wheel assembly and the condenser cavity assembly are key components of the projector, and the entry of dust will cause It will cause pollution to the color wheel assembly and light collecting cavity assembly, thereby polluting the optical path system, causing color cast and uniformity decrease in the picture displayed by the projector, and the deposition of dust will also affect the rotation of th...
