Description
Technical field
The utility model relates to a kind of blackboard for education, is specifically related to one and can collects dust blackboard for education, belong to teaching equipment technical field.
Background technology
Blackboard for education not refers in particular to the plate face of black, traditional sense is said it be one can the plane of repeated writing, plate face is hard, is used for teaching.Make with plank or ground glass etc., can to write above with specific writing materials such as chalks.Mostly be black, blackish green, white or ecru, general, in teaching process, teacher is many to give a lecture student with a lot of writing on the blackboard of chalk-writing and imparts knowledge to students on blackboard.But on the blackboard of limited areal, can not the too many blackboard writing font of disposable accommodation, so after often writing a full screen blackboard, after needing to carry out on-the-spot wiping to blackboard, more again write on blackboard.Reciprocating blackboard eraser both wiping blackboard chalk writings when erasing the board, in the process of motion, the dust of chalk writings is kicked up again, the dust kicked up constantly is rolled with air, is kicked up on front side of blackboard, this causes great dust pollution to blackboard-cleaning person, pollute classroom air and environment, to such an extent as to dust is sucked lung by Faculty and Students, bring the personal injury of Faculty and Students' respiratory system, great hidden danger is brought to user, for this reason, we propose one and can collect dust blackboard for education.
Utility model content
The technical problems to be solved in the utility model overcomes existing defect, there is provided one can collect dust blackboard for education, whole board can be wiped clean fast by blackboard eraser, dust can be made to fall into feeder inside by baffle plate, dust is prevented to occur disorderly flying phenomenon, overcome the slow and air-polluting deficiency that traditional blackboard is wiped, effectively can solve the problem in background technology.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
The utility model provides one can collect dust blackboard for education, comprise blackboard body, described blackboard body comprises board and blackboard eraser, and described blackboard body top and bottom are provided with chute, and described chute one end is provided with a grade part, described chute connects blackboard eraser, described blackboard eraser is the blackboard eraser with board equal altitudes, and described blackboard eraser both sides are provided with baffle plate, and described blackboard eraser top connects handrail, be provided with groove bottom described board and between chute, above described groove, be provided with feeder.
As a kind of optimal technical scheme of the present utility model, described blackboard eraser is flexibly connected chute by saddle, and described chute is that one end closes, the chute that the other end opens wide.
As a kind of optimal technical scheme of the present utility model, be pedestal in the middle of described blackboard eraser, described pedestal is implanted with hairbrush, and described hairbrush is uniformly across dust suction sponge, and described dust suction sponge periphery is provided with the flexible glue skin a little less than hairbrush.
As a kind of optimal technical scheme of the present utility model, described barrier width is slightly less than the width of blackboard eraser, and described baffle plate is the baffle plate of top seal, bottom-open.
As a kind of optimal technical scheme of the present utility model, described handrail connects blackboard eraser by nut, and described feeder is cuboid, and described feeder is flexibly connected groove.
The beneficial effect that the utility model reaches is: one can collect dust blackboard for education, whole board can be wiped clean fast by blackboard eraser, dust can be made to fall into feeder inside by baffle plate, prevent dust to occur disorderly flying phenomenon, overcome the slow and air-polluting deficiency that traditional blackboard is wiped, its structure is simple, and easy to use, cost is lower, be convenient to clean, can not contaminated air, for teacher provides a good working environment, there is promotional value.
