Description
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of environment-friendly dust-proof eraser.
Background technology
For a long time, blackboard is the necessary supply of classroom instruction always, writes resources material for academics and students, but due to the limited area of blackboard, and course content is a lot, therefore must constantly use blackboard eraser to clear up blackboard.
Being made up of gypsum of chalk, the main component of gypsum is calcium sulfate.Write with chalk writing on the blackboard, is to be coated on blackboard by gypsum powder.When erasing the board, Gypsum dust (chalk dust) in atmosphere of short duration wave after to fall object near blackboard and on the ground.Its particle is comparatively large, and how more than 100 microns, heavier, fall very fast, the time of aloft floating is short.From the above, the particle of chalk dust is comparatively large, scarcely can be drawn into respiratory tract, add that again gypsum is to human non-toxic, and medical circle does not also cause the report of PUD D so far because sucking chalk dust.
The blackboard used due to the various kinds of schools of China and chalk remain based on traditional blackboard and chalk, use this blackboard of blackboard eraser wiping not only time-consuming but also require great effort, when erasing the board, tedious chalk dust can dance in the air all over the sky, drop on desk, before dais, be even inhaled in the body of people, affect mood, more unhealthful.
Therefore for the situation that chalk dust when erasing the board dances in the air everywhere, need to improve blackboard eraser.
Utility model content
The utility model is exactly for the problems referred to above, proposes a kind of structure simple, can spray water during blackboard wiping, adsorption of dust, and the environment-friendly dust-proof eraser that synchronously can dry up blackboard.
The technical solution of the utility model is achieved in that a kind of environment-friendly dust-proof eraser, comprise the cleaning part of body and body bottom portion, described body interior is provided with power slot, water spray box and air-supply groove, the central authorities of described cleaning part are divided into wiping district by dividing plate and blot district, described inside, wiping district is communicated with described water spray box, outside covering cleaning wiping cloth, soft dry thing is filled in described inside, district of blotting, described air-supply groove blots side, district near described, and close to the edge of described body, the bottom of described air-supply groove is provided with air vent.
Described cleaning part is less than described body.
Further, described air-supply groove is concordant with the edge of described cleaning part along the inner side in body length direction.
The bag content that described dry thing is made up of cotton.
The long limit of described body is configured to arcuation.
The beneficial effects of the utility model are: cleaning part is divided into two by the utility model, and wiping district is connected with water spray box, moistening cleaning wiping cloth, can effective dust adsorption; Blot the built-in dry thing in district, absorb in time the dregs on the blackboard surface after wiping, and rapidly the blackboard surface after wiping is dried up by the wind that groove of blowing sends, thus do not affect writing below.
