(2) background technology:
At present, have now and big group of the cleaning device that once had, have the technology of the cleaning device group of sucking chalk powder device 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 23rd 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 the cleaning device group of sucking chalk powder device 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 the effect of twice blackboard.But still have some deficits, blackboard eraser was not inhaled dust before it also was difficult to solve, so that the people was caused the technical problem of injury.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of dust absorption blackboard eraser.Do not inhale dust with blackboard eraser before solving, so that the people is caused the technical problem of injury.
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: sponge, tub, aperture, impeller, axis, screw, motor, handle, lead, copper sheet, battery, spring constitute.Its screw, motor, lead, copper sheet, battery are by selecting for use on the market.Its aperture is a toroidal, through the drill-over processing and manufacturing.Its tub, handle are rectangular shapes, are material with wood, dig processing and manufacturing through saw.Its axis is a rectangular shape, is material with the steel, through the casting processing and manufacturing.Its spring is spiral-shaped, is material with the steel wire, through twining processing and 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: sandwich rubber is connected to the aperture position of tub, constitutes integrative-structure, and function has been to wipe the word effect.Motor screw is connected the centre position of handle, constitutes integrative-structure, and function has been that dynamic action is provided.Wire bonds is installed in the tail position of motor, constitutes integrative-structure, and function has been an electric action.Wire bonds is installed in the centre position of copper sheet, constitutes integrative-structure, and function has been an electric action.Wire bonds is installed in the bottom position of spring, constitutes integrative-structure, and function has been an electric action.The gluing location right that is installed in tub of handle constitutes integrative-structure, and function has been the assurance effect.In shape, structure and combination thereof, the dust absorption blackboard eraser of the present utility model technical characterictic different with immediate prior art is: the impeller screw is connected the apical position of axis, constitutes integrative-structure, and function has been to inhale the ash effect.Battery embeds the tip position that is installed in spring, and function has been that the power supply effect is provided.Blackboard eraser is not inhaled dust before so just having realized the solution of dust absorption blackboard eraser of the present utility model, so that the people is caused the purpose of the technical problem of injury.
The beneficial effect of the dust absorption blackboard eraser of utility model is: the utility model is not inhaled dust for blackboard eraser before solving, so that the people is caused big group of the technical scheme that technical problem adopted of injury and the existing and cleaning device about blackboard or slabstone that once had, has the technology of the cleaning device group of sucking chalk powder device to compare two advantages and improvement:
The first, owing to designed the apical position that the impeller screw is connected axis in the technical scheme of dust absorption blackboard eraser of the present utility model, constitute integrative-structure, so the technical problem of can easier solution inhaling ash.
The second, embed the tip position that is installed in spring owing to designed battery in the technical scheme of dust absorption blackboard eraser of the present utility model, so the technical problem of power supply can easier solution be provided.
(4) description of drawings:
Accompanying drawing provides the structural representation of dust absorption blackboard eraser of the present utility model:
