The beneficial effect of the dust suction chalkboard eraser of utility model is that the utility model is that solution is ash everywhere when erasing the board; Of long duration, also to shake off the dust on the blackboard eraser; Pollute big group of classmates' the technical scheme that technical problem adopted in living space and existing and the cleaning device that once had, have the technology of sucking chalk powder device group to compare three place's advantage and improvement about blackboard or slabstone:
The first, have suction port owing to designed the lower end position of rub body in the technical scheme of dust suction chalkboard eraser of the present utility model, be combined into the hole shape overall structure, so the technical problem of easier solution dust absorption passage.
Second, because an end position that has designed dry cell in the technical scheme of dust suction chalkboard eraser of the present utility model is movably arranged on the position of an end of resistance wire, one end position of resistance wire is fixedly mounted on the inner surface position on one side of battery case, be combined into the rectangular shape combining structure, so the technical problem of easier solution power supply power supply.
The 3rd, because an end position that has designed switch in the technical scheme of dust suction chalkboard eraser of the present utility model is connected the position of an end of battery case with lead, the other end position of battery case is connected the position of an end of Small-sized suction cleaner with lead, the other end position of Small-sized suction cleaner is connected the other end position of switch with lead, be combined into the triangle combining structure, so the technical problem of easier solution automatic dust absorption.
