Abstract
The invention discloses a magnetic blackboard eraser with a chalk box. The magnetic blackboard eraser comprises a felt, a chalk box cavity where chalk can be installed, a chalk box sliding door and a magnet arranged between the chalk box cavity and the felt, wherein the chalk box sliding door is arranged on the surface of the chalk box cavity away from the felt. The magnetic blackboard eraser is provided with the chalk box, a sponge is lined at the bottom of the box, the chalk in the blackboard eraser cannot swing when a user clean the blackboard through the blackboard eraser, the magnetic blackboard is convenient to carry, the user can take the chalk conveniently, and convenience can be brought to users. The magnetic blackboard eraser is magnetic, can be attracted at any place of an iron blackboard randomly and conveniently, does not need to be placed in a chalk groove under the blackboard, greatly reduces the chance of being stained by chalk dust and is favorable for reducing dust pollution in the air of a classroom.
Description
Technical field
The present invention relates to a kind of magnetism eraser, relate in particular to and a kind ofly can effectively reduce airborne dust in the classroom, guarantee the magnetism eraser with chalk holder of teachers and students' health.
Background technology
At present, classroom all uses green irony blackboard, after erasing the board with blackboard eraser, generally all whips blackboard eraser is placed in the ledge for chalk on blackboard below the blackboard.Because ledge for chalk on blackboard is mainly used in accepting chalk dust, the result causes and has been stained with chalk dust on the blackboard eraser, and chalk dust flies upward in the classroom so cause in using, and dust pollution is quite serious, if things go on like this can affect teachers and students' health.
