Abstract

The invention discloses a dust-free multifunctional blackboard. The blackboard comprises a dustproof curtain cover, a blackboard body and a blackboard wiping device, wherein the blackboard is arrangedon the blackboard body; a blackboard functional frame is arranged on the periphery of the blackboard, and a curtain groove is formed in the outer side of a sliding groove; the inner side of the curtain groove is provided with a dustproof curtain cover through a sliding rod; gas nozzles are further symmetrically arranged on the adjacent inner side of the sliding groove at the top side of the blackboard functional frame; an air pump is further fixedly arranged on the upper side of the top end of the blackboard functional frame; and the air pump communicates with the gas nozzles, and a controller is further arranged on the side wall of the blackboard functional frame. The dust-free multifunctional blackboard is provided with wiping brushes which are arranged on the side wall of a wiping device box body in a two-row structure, the two rows of wiping brushes are designed in a crossed structure, so that the wiping brushes can be mutually crossed and wiped to enable the wiping path to extendto the surface of the whole blackboard, and the phenomenon that the wiping is not clean due to the fact that a gap is reserved is avoided.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a dust-free multifunctional blackboard. Background technique [0002] The blackboard does not specifically refer to the black board surface. In the traditional sense, it is a plane that can be repeatedly written with chalk. The board surface is hard and is mostly used for teaching. Blackboards are generally made of wood or frosted glass, and can be written on with specific writing materials such as chalk. Mostly black, dark green, white or beige. [0003] The blackboard is one of the most commonly used tools for daily teaching and training. Most of the blackboards currently used are traditional blackboards, which have a limited surface area for writing and need to be manually wiped, which will produce a lot of chalk dust, serious dust pollution, and harmful to health. At the same time, the process of wiping and manually pushing and pulling multiple blackboards is time-con...
