Description
(1) technical field:
The utility model relates to dust absorption blackboard eraser, divides by International Patent Classification (IPC) (IPC) to belong to operation, Department of Transportation, and 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 technical field of sucking chalk powder device group.
(2) background technology:
At present, have now and big group of the cleaning device that once had, have the technology of sucking chalk powder device group that the demand of 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 on the 28th October in 2002 by Wang Haining, Granted publication number is CN2517591Y, China Patent No. (ZL) is: No. 01228599.5 utility model patent title is the utility model patent of " dust-free black board eraser ", the technical scheme that is adopted.Big group of the cleaning device of blackboard or slabstone, the technical elements that sucking chalk powder device group is arranged are routine of great value inventions, and it has solved effectively to wipe and once has been equivalent to the technical problem that other blackboard eraser has been wiped twice effect.But still have some deficits, it also is difficult to solve the too many technical problem of chalk dust.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of dust absorption blackboard eraser.To solve the too many technical problem of chalk dust.
The dust absorption blackboard eraser that the new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is achieved in that this utility model mainly by: handle, plank, battery case, hairbrush, dust catcher, put the dirt mouth, air suction opening constitutes.Its handle, hairbrush, dust catcher are by selecting for use on the market.Its plank, battery case are rectangular shapes, are material with timber, through the planing operation manufacturing.
In shape, structure and combination thereof, the total essential features of dust absorption blackboard eraser of the present utility model and immediate prior art is: the handle screw is installed in the last position of plank, is combined into the fixed structure of arc shape, and function has been the convenient effect of taking.The bonding upper/lower positions that is installed in battery case of hairbrush constitutes oblong-shaped, and function has been the effect of erasing the board.In shape, structure and combination thereof, the dust absorption blackboard eraser of the present utility model technical characterictic different with immediate prior art is: battery case is bonded in the upper/lower positions of plank, be combined into the fixed structure of rectangular shape, function has been discharger and dust catcher effect.So just realized the purpose of the technical problem that the solution chalk dust of dust absorption blackboard eraser of the present utility model is too many.
The beneficial effect of the dust absorption blackboard eraser of utility model is: the utility model has the technology of sucking chalk powder device group to compare an advantage and improvement for solving big group of too many technical scheme that technical problem adopted of chalk dust and the existing and cleaning device about blackboard or slabstone that once had:
The first, owing to designed the upper/lower positions that battery case is bonded in plank in the technical scheme of dust absorption blackboard eraser of the present utility model, be combined into the fixed structure of rectangular shape, so can easier solution discharger and the technical problem of dust catcher.

Fig. 2: the structural representation of looking up that is dust absorption blackboard eraser of the present utility model:
The label declaration of parts in the schematic diagram:
1 handle, 2 planks, 3 battery cases, 4 hairbrush
5 dust catchers 6 are put dirt mouth 7 air suction openings
(5) specific embodiment:
Below in conjunction with accompanying drawing, be that the optimal way that realization solves the technical scheme that the too many technical problem of chalk dust takes is described further to dust absorption blackboard eraser of the present utility model:
Its static structure: please join accompanying drawing: as shown in the figure, dust absorption blackboard eraser of the present utility model mainly by handle 1, plank 2, battery case 3, hairbrush 4, dust catcher 5, put dirt mouth 6, air suction opening 7 constitutes.Its handle 1, hairbrush 4, dust catcher 5 are by selecting for use on the market.Its plank 2, battery case 3 are rectangular shapes, are material with timber, through the planing operation manufacturing.
In shape, structure and combination thereof, the total essential features of dust absorption blackboard eraser of the present utility model and immediate prior art is: handle 1 screw is installed in the last position of plank 2, is combined into the fixed structure of arc shape, and function has been the convenient effect of taking.The hairbrush 4 bonding upper/lower positions that are installed in battery case 3 constitute oblong-shaped, and function has been the effect of erasing the board.In shape, structure and combination thereof, the dust absorption blackboard eraser of the present utility model technical characterictic different with immediate prior art is: battery case 3 is bonded in the upper/lower positions of plank 2, be combined into the fixed structure of rectangular shape, function has been discharger and dust catcher effect.
Below by using method, further set forth the dynamic structure relation of this practical dust absorption blackboard eraser: in use, when erasing the board, open dust catcher 5, its dust catcher 5 acts on dust by air suction opening 7, thereby finishes the task of dust suction.So just realized the purpose of the technical problem that the solution chalk dust of dust absorption blackboard eraser of the present utility model is too many.
Realize that preferred plan of the present utility model is is material with wood, utilize the basic equipment of blackboard eraser factory, batch produce by batch in taking, the demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
