Abstract

The invention discloses dustproof equipment based on a box body, and the equipment comprises a rectangular housing. The interior of the housing is provided with a built-in lens, and an image outgoing surface of the lens is provided with a side dustproof plate which is located on a side surface of the housing and is connected with a top dustproof plate. The top dustproof plate is located at the top of the lens and on the upper surface of the housing. The top dustproof plate and the side dustproof plate are respectively in movable connection with the housing. When the top dustproof plate and the side dustproof plate are closed, a rectangular body is formed; when the top dustproof plate and the side dustproof plate are opened, a rectangular groove with a groove is formed. When the top dustproof plate and the side dustproof plate are closed, the inner walls of the top dustproof plate and the side dustproof plate are respectively provided with a dirt removing block. The dirt removing blocks are rectangular, wherein one surface of each dirt removing block is connected with one inner wall of the dustproof plates, and the opposite surface of the connection surface is provided with a plurality of roller shafts. The surfaces of the roller shafts are provided with dirt removing cloth. The equipment also comprises a control key, and the control key controls the rotating of the roller shafts. The contact surfaces of the dustproof plates with the lens are provided with the dirt removing blocks, wherein the number of the dirt removing block is not less than two.

Description

technical field [0001] The invention relates to an anti-dust of a projector lens, in particular to a box-based anti-dust device. Background technique [0002] In the field of modern education, with the development of computer and information technology, multimedia teaching is becoming more and more popular as an advanced teaching method. All kinds of education and training units are building multimedia classrooms or multi-functional halls. The traditional construction plan is to equip projectors, computers, projection screens, DVD players, power amplifiers, speakers, wireless microphones and other equipment to achieve sound, image, text and other equipment. Synchronized teaching effect. [0003] At present, the projectors in the multimedia hall are generally fixed at a place higher than the ground, and the lens is usually exposed for a long time, and the dust accumulated on the lens directly affects the projection effect of the projector. In existing projectors, some use l...
