Intelligent teaching blackboard

Abstract

The invention discloses an intelligent teaching blackboard. A writing wall is arranged on a wall body, and a dust treatment platform is further arranged on the wall body. A first dust suction cavity is formed in the dust treatment platform, and a plurality of dust suction heads which are arranged side by side are arranged on the dust treatment platform. The dust treatment platform is provided witha sliding dust suction sliding block, the end part of a first dust suction pipe is connected with a blackboard eraser, and a plurality of dust suction heads which correspondingly communicate with thefirst dust suction pipe are connected to the blackboard eraser. The two ends of the dust treatment platform are each provided with a chalk making module, and a mixing stirring cavity which communicates with the first dust suction cavity is arranged in each chalk making module. When the blackboard eraser is used for wiping the blackboard, powder can be adsorbed through the dust suction heads. Meanwhile, the powder in the chalk making modules can be used for mixing and stirring so that the purpose of making chalk can be achieved, and the teaching input is further reduced.

Description

technical field [0001] The invention relates to a teaching blackboard, in particular to an intelligent teaching blackboard, in particular to an intelligent teaching blackboard capable of remaking chalk powder into chalk. Background technique [0002] With the continuous submission of education levels, the continuous improvement of teaching equipment has been further promoted. Among the current teaching equipment, the blackboard is one of the necessary equipment, so that it is possible to write on the blackboard to complete the teaching. Among them, in the teaching Most of the process is to use chalk to write on the blackboard. Since the chalk is made of powder, it is necessary to wipe the traces of the chalk with a blackboard eraser after writing. Although the purpose of wiping the traces can be achieved through the blackboard eraser, there are still The following questions: [0003] In the process of wiping chalk traces with blackboard eraser, a large amount of dust will b...

AI Technical Summary

Problems solved by technology

[0003] In the process of wiping chalk traces with blackboard eraser, a large amount of dust will be generated, which will cause certain physical injuries to students and teachers, and after wiping the chalk traces, there will be a large amount of powder remaining on the bottom of the blackboard. The process of cleaning the remaining powder will also cause the dust to fly, which will further cause secondary physical injury to students and teachers, and further increase the teaching cost due to the large amount of chalk used.
