The invention relates to the technical field of a photoelectric information technology apparatus, and discloses a deviation-preventing optical novel projection apparatus. The deviation-preventing optical novel projection apparatus comprises a projector shell; an operation and control box is fixedly mounted in the middle part of the top surface of the projector shell; the bottom of the operation and control box extends to an inner cavity of the projector shell, and is fixedly sleeved with a dust collection block; the top of the dust collection block extends to the inner cavity of the operationand control box, and is fixedly connected with an air guiding pipe; the exterior of the air guiding pipe is fixedly sleeved with a fixed plate; and the exterior of the fixed plate is fixedly connectedwith the inner wall of the operation and control box. According to the photoelectric information technology apparatus, an air extracting pump is arranged to ventilate the interior of the projector shell to drive internal air of the projector shell to flow to enable dust to enter a dust collection frame through an air inlet along with air; and next, the air is discharged through a filtering net, and the dust is accumulated in a dust collection box, so that the dust can be cleaned in a centralized manner, thereby avoiding the problem of influence to the projection definition caused by internaldust accumulation of the projector shell and improving safety of the apparatus.
Description
technical field [0001] The invention relates to the technical field of optoelectronic information technology devices, in particular to a new type of anti-deviation optical projection device. Background technique [0002] Optics is the science that studies the law of light wave propagation. To study how light propagates to the earth from galaxies outside the Milky Way several million years away; to study how the light illuminates the specimen through the condenser lens in the microscope, then forms an image through the objective lens, magnifies through the eyepiece, and finally projects through the lens of the eye to the entire retina. Process; study the refraction of distant villages and lakes through the scorching atmosphere above the desert, forming the spectacle of mirages. Optics is the science that studies the interaction of light waves with matter. Study the photosynthesis of plants under sunlight; study the changes in photosensitive emulsion caused by light waves ir...
