Electric curtain top mechanism with patting type dust removal mechanism

Abstract

The invention relates to the technical field of teaching aids, in particular to an electric curtain top mechanism with a patting type dust removal mechanism. The electric curtain top mechanism comprises a horizontal main shell, an opening is formed in the lower end of the horizontal main shell, a horizontal main rotating shaft and a horizontal auxiliary rotating shaft are arranged inside the horizontal main shell, a projection curtain winds around the horizontal main rotating shaft, a left function base is fixedly connected to the left side of the horizontal main shell, and a right function base is fixedly connected to the right side of the horizontal main shell. According to the electric curtain top mechanism with the patting type dust removal mechanism, a low-speed motor used for retracting and releasing the curtain and a small vacuum centrifugal pump used for patting the surface of the curtain and removing dust are installed on the two sides of the horizontal main shell respectively, and therefore the dust accumulated on the surface can be automatically removed in the retracting process of the curtain each time, the surface cleanliness of the curtain can be improved, and the service life of the curtain can be greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to an electric curtain top mechanism with a beating dust removal mechanism. Background technique [0002] With the development of science and technology, especially optical technology, people use projection technology to greatly improve the efficiency of classroom teaching. In order to improve the display efficiency of projection, it is often necessary to install projection screens in classroom teaching areas. However, with the normal use time of screens, A large amount of dust will accumulate on the surface, which will seriously affect the anti-reflective ability of the surface of the curtain, resulting in a decrease in the display effect of the curtain and a greatly reduced service life. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, an ...
