Description

A fully automatic dust-free blackboard

technical field

The invention relates to the technical field of teaching equipment, in particular to a fully automatic dust-free blackboard.

Background technique

Teaching is a human-specific talent cultivation activity composed of teachers' teaching and students' learning. Through such activities, teachers guide students to learn and master cultural and scientific knowledge and skills purposefully, in a planned and organized manner, and promote the improvement of students' quality, so that they can become the people needed by society.

The blackboard does not specifically refer to the black board surface. In the traditional sense, it is a plane that can be written repeatedly. The board surface is hard and is mostly used for teaching. Made of wood or frosted glass, you can use specific writing materials such as chalk to write on it, mostly black, dark green, white or beige.
