Environment-friendly teaching blackboard with dust collecting effect

Abstract

The invention discloses an environment-friendly teaching blackboard with a dust colleting effect and relates to the field of teaching blackboard devices. The environment-friendly teaching blackboard comprises a blackboard frame body and a bottom box. The bottom box is fixedly arranged at the bottom of the backboard frame body. A panel is arranged on one side of the front face of the blackboard frame body. Grooves are formed in the two sides of the panel, and one sides of the grooves extend in inner cavities of the two side walls of the blackboard frame body. A board eraser body is movably arranged between the grooves in the two sides, and the board eraser is connected with the panel in an attached manner. A dust collecting groove is formed in an inner cavity of the bottom box, and a chalkdust contracting basket is movably arranged in the dust collecting groove. One end of the chalk dust collecting basket penetrates one side wall of the bottom box and extends to one side of the outer wall of the bottom box, and a drawing plate is arranged on one side of the outer wall of the bottom box. The environment-friendly teaching black board is simple in structure and convenient to operate,compared with an existing traditional blackboard, the intelligence degree is high, automation can be achieved, in addition, generated chalk dust can be collected, and the environment friendliness effect is achieved.

Description

technical field [0001] The invention relates to the field of blackboard devices for teaching, in particular to an environment-friendly teaching blackboard with dust collecting effect. Background technique [0002] Nowadays, teaching writing tools generally use computer teaching technology, but there are still many professors who are accustomed to using the traditional writing habit and teaching while writing on the blackboard. [0003] However, the existing traditional blackboards are all manually wiped with a blackboard eraser, but such a wiping method is relatively simple, and it is easy to produce a large amount of chalk dust, and the generation of chalk dust will fall randomly, which is easy to cause environmental pollution. It is also easy to cause physical harm to students or learners. Therefore, it is necessary to invent a kind of environmental protection teaching blackboard with dust collecting effect to solve the above problems. Contents of the invention [0004...
