Automatic cleaning protection device for lens after use of projector

Abstract

The invention relates to the technical field of software development, and discloses an automatic cleaning protection device for a lens after use of a projector. The automatic cleaning protection device comprises a shell, the inner side of the shell is movably connected with a closing mechanism, the closing mechanism comprises a translation assembly and a detection assembly, and the translation assembly is movably connected to the inner side of the shell; the detection assembly is movably connected into the translation assembly, and the outer side of the closing mechanism is movably connected with a cleaning mechanism. Through clamping of a short rod and a rack on the outer side of a flat plate, when the short rod moves along with a rotating block, the two flat plates are closed, and meanwhile, the two flat plates enable a special-shaped rod to pass through a through hole of a second shell, so that dust and the like falling on a projector lens can be cleaned when a user stops using the projector; and the two flat plates are in a closed state, so that external dust and the like can be prevented from falling on the lens, and the lens can be kept clean when the user uses the lens next time.

Description

technical field [0001] The invention relates to the technical field of software development, in particular to an automatic cleaning protection device for a projector lens after use. Background technique [0002] Software development is the process of building a software system or software part of the system according to user requirements. Software development is a system engineering that includes requirements capture, requirements analysis, design, implementation and testing. [0003] In the process of software development, it is necessary to show the development process to the customer to determine whether it needs to be modified. A projector is required for animation demonstrations, but the dust or stains on the lens need to be cleaned after the projector has been used for a period of time, otherwise The projected picture will be blurry, the display effect is not good, and some projectors are placed at a high position, the cleaning personnel need to use chairs or tools to ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an automatic cleaning and protection device for the lens of the projector after use, which has the advantages of cleaning the lens of the projector after use, which is convenient for the cleaning personnel to perform cleaning work, and solves the problem that the projector is in use. After the dust falls on the lens, it affects the clarity of the image when the lens is projected. It is troublesome for the cleaning personnel to clean up and may damage the lens.
