Description
The utility model relates to novel dust absorption blackboard eraser.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) classification, printing branch is write or drawing appliance, the big class of office appliance is write or drawing article, the assistant product group of writing or draw, big group of the cleaning device of blackboard or slabstone has the little technical group field of sucking chalk powder device.Be numbered B43L 2/O2.
At present, have now and big group of the cleaning device that once had, have the technology of the group of sucking chalk powder device that the demand of novel dust absorption blackboard eraser was all done very fruitful effort, also once designed many outstanding technical schemes about blackboard or slabstone.As declaring of the Decree of Patent Office of China in 1996 by Gu Zhengwu, Granted publication number is CN2243398Y, China Patent No. (ZL) is: No. 95221145.9 utility model title is the utility model patent of " drum-type dust-absorbing blackboard brush ", the technical scheme that is adopted.Big group of the cleaning device of blackboard or slabstone, group's technical elements that the sucking chalk powder device is arranged is a routine of great value invention, and it has solved the problem of blackboard brush drum-type dust suction effectively.But still have some deficits, its also be difficult to solve erase the board simultaneously can dedusting problem.
The purpose of this utility model is to provide a kind of novel dust absorption blackboard eraser.With solution erase the board simultaneously can dedusting problem.
The purpose of this utility model is achieved in that the novel dust absorption blackboard eraser of this utility model.Mainly constitute by battery case, brush board, bristle, dust catcher, handle, switch.The handle of its semi-circular shape adopts fixing means to be installed on the brush board of rectangular shape, forms the superstructure of a semi-circular shape.The dust catcher of its rectangular shape adopts fixing means to be installed on the brush board of rectangular shape.Form the internal structure of a rectangular shape.The bristle of its needle-like shape adopts adhesive method to be installed on the brush board of rectangular shape.Form the polycrystalline substance of a Brush Shapes.Its bristle by cementation in brush board, thereby make bristle satisfy the requirement of erasing blackboard.Its dust catcher by fixation in brush board, thereby make dust catcher finish the task of dust suction.So just realized the purpose of this utility model.
Big group of the cleaning device of the utility model and original blackboard or slabstone has group's technology of sucking chalk powder device to compare three advantages and improvement;
The first, because the utility model has designed bristle in technical scheme, so solved the problem that can erase the board;
The second, because the utility model has designed dust catcher in technical scheme, so solved the problem that can inhale dust;
The 3rd, because the utility model has designed handle in technical scheme, so solved the problem that can conveniently take blackboard eraser.Thereby just can more effectively solve erase the board simultaneously can dedusting problem.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the contour structures schematic diagram of novel dust absorption blackboard eraser of the present utility model;
The numbering of parts explanation in the schematic diagram: 1 battery case, 2 brush boards, 3 bristles, 4 dust catchers, 5 handles, 6 switches
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, dust-collecting eraser for blackboard of the present utility model. Mainly by battery case 1, brush board 2, bristle 3, dust catcher 4, handle 5, switch 6 consist of. Its major part dust catcher 4 by selecting on the market. Its handle 5 is semi-circular shapes, makes material with plastics, through hot forming Processing and manufacturing. Its brush board 2 is pane shapes, makes material with wood, through planing processing system Make. Its bristle 3 is aciculiform shapes, makes material with bristle, through synthetic processing and manufacturing. Its half The handle 5 of circular shape adopts fixing means to be installed on the brush board 2 of rectangular shape, forms one The superstructure of semi-circular shape. The dust catcher 4 of its rectangular shape adopts fixing means to be installed in On the brush board 2 of rectangular shape. Form the internal structure of a rectangular shape. Its needle-like shape The bristle 3 of shape adopts the bonding method to be installed on the brush board 2 of rectangular shape. Form a brush The polycrystalline substance of shape. Its bristle 3 by cementation in brush board 2, thereby make bristle 3 Satisfy the requirement of brush blackboard. Its dust catcher 4 by fixation in brush board 2, thereby make dust suction Device 4 is finished the task of dust suction. So just realized the purpose of this utility model. Thereby just can solve Erase the board simultaneously can dedusting problem.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, in force, if erase the board and do not want to allow dust damage the person's of erasing the board health, arrest handle 5 with hand, blackboard eraser is put into bar switch 6 on the blackboard, make dust catcher 4 in running order, at this moment with the hand blackboard eraser that moves around, just can reach the dedusting purpose.Thereby just can realize the purpose of this utility model.
Realize that preferred plan of the present utility model is is material with plastics, wood, utilize the basic equipment of blackboard eraser factory, take hot forming, assembling to produce by batch, the demand with supply educational circles so just can realize practical value of the present utility model and economic worth better.
