Abstract
The invention relates to the field of teaching supplies, in particular to a dust collection blackboard eraser. The dust collection blackboard eraser comprises a blackboard eraser body and bristles and is characterized in that a handle is mounted on the upper bottom face of the blackboard eraser body, the handle is provided with a switch, the bristles are mounted on the lower bottom face of the blackboard eraser body, a magnet and a charging port are mounted on the side face of the blackboard eraser body, and a dust collection box, a minitype dust collector and a storage battery are arranged inside the blackboard eraser body. The dust collection blackboard eraser is simple in structure, convenient to use and capable of saving labor, when a blackboard is cleaned, the minitype dust collector can suck chalk powder into the dust collection box by turning on the switch, the classroom environment can be prevented from being polluted, cleaning is easy, the blackboard eraser can be attracted on the blackboard through the magnet after using is completed, and the blackboard eraser can be taken conveniently and be suitable for being widely applied and popularized.
Description
(1) technical field
The present invention relates to realia field, particularly a kind of black board eraser with chalk-dust collector.
(2) background technology
Blackboard eraser is requisite instrument on dais, classroom, blackboard eraser in use, a large amount of chalk powders can be produced, although present chalk has been much dust-free chalk, when being only limitted to write, also there is minimizing dust in blackboard eraser, but the time has been grown and still had many chalk powders and overlay on blackboard eraser, or falls within the below of blackboard, cleaning has been got up very unavoidably, and easily pollute classroom environment, bring harm to the health of academics and students.
(3) summary of the invention
