A dust-proof and heat-dissipating projector

Abstract

The invention discloses a dust-proof and heat-dissipating projector, comprising a projector body and an activated carbon adsorption net. The right side of the front side of the projector body is provided with a protection cover, the shape of the protection cover is rectangular, an air purifier is arranged at the top end of the projector body, and a direct current motor is arranged at the bottom end of the second bracket. An air purifier is provided, which is convenient for the user to purify the ambient air, the harmful gases such as indoor formaldehyde and the like are avoided from causing harm to human body, so as to improve the physical and mental health of users, Setting protective cover, which is convenient for the user to protect the projector body. The invention avoids the damage problem of the projector body caused by the impact of external force, improves the safety of the projector body when placed, and provides a direct current motor and a fan blade, which can facilitate theuser to radiate heat from the projector body, avoids the problem that the heat in the projector body is difficult to be discharged and causes the component damage, and prolongs the service life of the projector body.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to a dustproof projector with good heat dissipation effect. Background technique [0002] The projector is an optical instrument that uses optical elements to enlarge the contour of the workpiece and project it on the screen. It can use transmitted light for contour measurement, and can also use reflected light to measure the surface shape of the non-through hole and observe the surface of the part. Projection A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. [0003] However, the projectors currently on the market have complex structures and single functions. There is no air purifier, which makes it difficult for users to purify the surrounding air. There is no protective cover, which makes...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a projector that is dust-proof and has a good heat dissipation effect, which can effectively solve the problems mentioned above in the background art that there is no air purifier, which makes it difficult for the user to purify the surrounding air, and the lack of a protective cover, which makes it difficult for the user to monitor the projector. The main body of the projector is protected, and there is no DC motor and fan blades, so it is not convenient for the user to dissipate heat from the main body of the projector.
