Problems solved by technology

[0002] Information projectors are becoming more and more common now, not only in schools, but also in many hospitals, companies and even people’s homes. At that time, there was a problem with information projectors, especially classroom projectors, because they needed to be used for teaching, so they had high requirements for clarity. Good, but after a holiday, the projector has not been used for a long time, resulting in dust on the inside, which is very inconvenient to clean

Abstract

The invention discloses a projection dustproof device for an information technology. The projection dustproof device comprises an upper shell, and a transmission cavity is formed in the upper shell. Atransmission assembly is arranged in the transmission cavity. A left separation cavity is formed in the left end wall of the transmission cavity, and a right separation cavity is formed in the rightend wall of the transmission cavity. An upper closed cavity is formed on the right side of the transmission cavity. The right side of the upper closed cavity is communicated with an upper sliding cavity, an opening of the upper sliding cavity is downward, and a sealing assembly is arranged in the upper closed cavity. When the information projector is not used, the information projector is well protected, the lens is sealed and protected, the situation that the image definition is reduced due to the fact that dust enters the lens is prevented, and meanwhile an adjusting assembly capable of automatically rotating is designed to adapt to the requirement for tiny adjustment to achieve a better projection effect.

Description

technical field [0001] The invention relates to the technical field of information technology, in particular to a projection dustproof device for information technology. Background technique [0002] Information projectors are becoming more and more common now, not only in schools, but also in many hospitals, companies and even people’s homes. At that time, there was a problem with information projectors, especially classroom projectors, because they needed to be used for teaching, so they had high requirements for clarity. Good, but after a holiday, the projector has not been used for a long time, resulting in dust on the inside, which is very inconvenient to clean. [0003] Therefore, an automatic dust-proof information projector is needed to solve this problem. Contents of the invention [0004] In view of the deficiencies of the above-mentioned technologies, the present invention proposes a projection dust-proof device for information technology, which can overcome th...
