Description
Technical field
The utility model relates to teaching aid technical field, particularly, relates to a kind of novel blackboard eraser.
Background technology
Chalk is made up of gypsum, and 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.
When erasing the board, tedious chalk dust can dance in the air all over the sky, drops on desk, before dais, is even inhaled in the body of people, affects mood, more unhealthful.Will write writing on the blackboard because attend class every day, erase the board, chalk dust often makes with dishevelled hair and a dirty face teacher.Generally speaking, a middle school Chinese language teacher, on the joint class of 45 minutes, need the writing on the blackboard writing a blackboard, and the writing on the blackboard of a blackboard approximately needs to use up half chalk; And a middle school mathematics teacher or English teacher one class often need the writing on the blackboard writing blackboard, the chalk of 2 half of approximately will using up.And the teacher of graduating class needs at most six class in one day.It multiple one day, year after year, teacher made the chalk quantity of using up considerable in career.And classmates are being full of the environment learning of chalk dust, not only have impact to health, be more unfavorable for being absorbed in studies, the student on duty especially erased the board suffers untold misery especially.
Although disclosed multiple blackboard eraser in prior art, but effectively can not solve the problem that dust descends slowly and lightly in actual applications.
Utility model content
For the problems referred to above of the prior art, the utility model proposes a kind of novel blackboard eraser efficiently solving the problem that dust descends slowly and lightly everywhere.
Of the present utility modelly provide a kind of novel blackboard eraser, comprise blackboard eraser body and be arranged on the bristle on blackboard eraser body cross side, wherein:
Be provided with micro-cleaner in described blackboard eraser body, the cross side being provided with bristle of described blackboard eraser body is also provided with multiple air suction opening, and described air suction opening is connected with described micro-cleaner;
Two longitudinal sides of described blackboard eraser body are respectively arranged with stripe board, and described stripe board is provided with block piece on the direction consistent with described bristle setting direction;
The opposite side that bristle is not set of described blackboard eraser body also offers opening, described micro-cleaner is arranged in described opening, described micro-cleaner is connected with supply unit mounted thereto, started by the switch be arranged on described supply unit or close described micro-cleaner
Described opening is also covered with lid.
Further, described stripe board is rotating by rotating shaft relative to described blackboard eraser body.
Further, the length of described block piece is longer than the length of described bristle.
Further, described block piece is sponge.
Compared with prior art, the beneficial effects of the utility model are:
By being arranged on the micro-cleaner in blackboard eraser body, then can suck some dust, meanwhile, block piece is set by the both sides in blackboard eraser body, effectively can place dust be scattered thus sucked by dust catcher, thus avoid dust to descend slowly and lightly and the defect of health risk and contaminated environment everywhere.
