(3) summary of the invention:
The purpose of this utility model is to provide a kind of dust absorption blackboard eraser.When erasing the board with solution with the technical problem in the chalk dust the wiped inspiration simultaneously blackboard eraser.
The 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: rub body, loam cake, chute, battery case, electric wire, motor, fan, air suction opening, switch, screen cloth, steam vent constitute.Its battery case, electric wire, motor, switch are by selecting for use on the market.Its rub body is a rectangular shape, uses plastic material, through the injection moulding processing and manufacturing.Its loam cake is a rectangular shape, uses plastic material, through the injection moulding processing and manufacturing.Its chute is a rectilinear form, through the machining manufacturing.Its fan plastic material is through the injection moulding processing and manufacturing.Its air suction opening is round-shaped, through the boring processing and manufacturing.
In shape, textural, the total essential features of dust absorption blackboard eraser of the present utility model and immediate prior art is: electric wire in the binding post position of battery case, motor and switch, constitutes Welding Structure with welded and installed, and function has been an electric action.The battery case screw is installed in the inner wall position of rub body, constitutes the convex form syndeton, and function has been that battery and power supply effect are installed.The fan screw is installed in the connecting axle position of motor, constitutes syndeton, and function has been the dust suction effect.Switch embeds the rear positions that is installed in rub body, constitutes the interspersed structure of convex shape, and function has been the control circuit function.The loam cake chute is mounted on the upper position of rub body, constitutes overall structure, and function has been to take off lid back dedust and change galvanic action.The bonding inside that is installed in rub body of screen cloth, around the motor, function has been the effect that stops that dust escapes.Steam vent boring is installed in the back side of rub body, and function has been the effect of circulation of air pipeline.In shape, textural, the utility model dust absorption blackboard eraser technical characterictic different with immediate prior art is: the motor screw is installed in the inwall middle position of rub body, constitutes the convex shape syndeton, and function has been to drive the fan running effect.The chute cutting is installed in top two side positions of rub body, constitutes the rail groove shape, and function has been and the loam cake mating reaction.Air suction opening boring is installed in the front position of rub body, constitutes round-shapedly, works allowing dust pass through to act on.When erasing the board with regard to the solution that has realized dust absorption blackboard eraser of the present utility model like this with the purpose of the technical problem in the chalk dust the wiped inspiration simultaneously blackboard eraser.
The beneficial effect of the dust absorption blackboard eraser of utility model is that the utility model is that solution has been compared three place advantage and improvement with existing with the technology about the cleaning device group of blackboard or slabstone that once had with technical problem adopted in the chalk dust inspiration simultaneously blackboard eraser of wiping technical scheme when erasing the board:
The first, owing to designed motor in the technical scheme of dust absorption blackboard eraser of the present utility model, easier solution drives the technical problem of fan transportation.
The second, owing to designed chute in the technical scheme of dust absorption blackboard eraser of the present utility model, so easier solution and loam cake compounding technique problem.
The 3rd, owing to designed air suction opening in the technical scheme of dust absorption blackboard eraser of the present utility model, so the technical problem that easier solution allows dust pass through.
