(3) summary of the invention:
The purpose of this utility model is to provide a kind of electric dust absorption blackboard eraser.When erasing the board with solution, the technical problem that dust flies upward.
The electric dust absorption blackboard eraser that the technical scheme that the technical problems to be solved in the utility model adopted is achieved in that this utility model mainly by: air suction opening, housing, screw, fan, dividing plate, screw, lead, battery case, motor, copper sheet, spring, battery, screw constitute.Its screw, fan, screw, lead, motor, copper sheet, spring, battery, screw are by selecting for use on the market.Its air suction opening is round-shaped, through the drill-over processing and manufacturing.Its housing is a rectangular shape, uses wood materials, through digging, glue processing and manufacturing.Its dividing plate is a rectangular shape, uses wood materials, through digging processing and manufacturing.
In shape, textural, the total essential features of electric dust absorption blackboard eraser of the present utility model and immediate prior art is: screw screws in the following placement of foot that is connected housing, and function has been to turn on down the ash effect.Separator glue is connected to the medium position of housing, constitutes integrative-structure, and function is to flake
In shape, textural, the total essential features of electric dust absorption blackboard eraser of the present utility model and immediate prior art is: screw screws in the following placement of foot that is connected housing, and function has been to turn on down the ash effect.Separator glue is connected to the medium position of housing, constitutes integrative-structure, and function is to flake from inhaling sheet and motor effect.The gluing upper position that is connected housing of battery case constitutes integrative-structure, and function has been that the power supply effect is provided.Spring is welded to connect the upper position at copper sheet, constitutes integrative-structure, and function has been the self-contained battery effect.In shape, textural, the utility model electric dust absorption blackboard eraser technical characterictic different with immediate prior art is: the motor screw is connected the bottom position of housing, constitutes integrative-structure, and function has been the effect of being used as power.The copper sheet screw is connected the end positions of battery case, constitutes integrative-structure, and function has been a power supply function.Battery inserts the terminal position that is installed in spring, and forming circuit structure, function have been power supply functions.When erasing the board with regard to the solution that has realized electric dust absorption blackboard eraser of the present utility model like this, the purpose of the technical problem that dust flies upward.
The beneficial effect of the electric dust absorption blackboard eraser of utility model is that the utility model is to solve when erasing the board, big group of technical scheme that the technical problem of flying upward dust adopts and the existing and cleaning device about blackboard or slabstone that once had have the technology of the cleaning device group of sucking chalk powder device to compare three place's advantage and improvement:
The first, owing to designed motor in the technical scheme of electric dust absorption blackboard eraser of the present utility model, so the technical problem that easier solution is used as power.
The second, owing to designed copper sheet and battery in the technical scheme of electric dust absorption blackboard eraser of the present utility model, so the technical problem of easier solution power supply.
The 3rd, owing to designed the fan dust absorbing structure in the technical scheme of electric dust absorption blackboard eraser of the present utility model, so easier solution has improved the technical problem of teaching and academic environment.
