Detailed description of the invention
At Fig. 1, 2, 3, in 4, the utility model relates to a kind of blackboard eraser, more specifically to a kind of automation blackboard eraser, comprise: tooth bar I, gear I, circular shaft I, gear II, circular shaft II, burr axle, suction opeing, deduster, gear III, motor, electromagnet I, wiping board, electromagnet II, tooth bar II, gear IV, circular shaft III, shell, blackboard, sensor I and sensor II, teacher is not needed in person to go to erase the board, button press drives workbench to move by motor just can be clean by blackboard eraser, and chalk dust is drawn in deduster by suction opeing, avoid the dust that produces in the process of erasing the board to teacher, the body harm that classmate brings.
For solving the problems of the technologies described above, it is overall that motor 10 provides power to drive, motor 10 is fixed on wiping board 12, rotated by circular shaft II5 driven gear II4, gear II4 driven gear III9 rotates, gear III9 is rotated by circular shaft I3 driven gear I2, and gear I2 drives shell 17 to move relative to blackboard 18 by tooth bar I1.Gear III9 drives burr shaft gear II6-2 to rotate by burr shaft gear I6-1, and burr shaft gear II6-2 driven gear IV15 rotates, and gear IV15 drives shell 17 to move relative to blackboard 18 by tooth bar II14.
Deduster 8 is fixed on wiping board 12, is connected on wiping board cylindrical cavity 12-3 by suction opeing 7, deduster 8 internal fan High Rotation Speed, produce Negative Pressure Difference, the air-flow entering dust-collecting box is from the outside very large, is enough to, the dust inspiration deduster 8 suspended, carry out dust suction, dust removal process.Can spot be removed when burr (6-3) rotates, and form certain air-flow, more be conducive to the dust suction effect of deduster 8.
Electromagnet I11 and electromagnet II13 is fixed on wiping board 12, when the switch is closed, coil electricity produces electromagnetic force, under the effect of electromagnetic force, the close contact of wiping board face I12-1, wiping board face II12-2 and blackboard 18 can be realized, when switch disconnects, electromagnetic force disappears, and can realize wiping board face I12-1, wiping board face II12-2 and be separated with blackboard 18.By electromagnet I11 and electromagnet II13, utilize electromagnetism adhesive principle, erasing apparatus can be contacted and depart from automatically with blackboard 18, thus realize at any time, the function of random erasing blackboard.Wiping board face I12-1 is different from the material of wiping board face II12-2, not only can wipe dust, can wipe other multiple spots.
Sensor I19 and sensor II20 is separately fixed on blackboard 18 two ends, can detect shell 17 and whether arrive border, if arrive border, makes motor 10 out of service, thus prevention blackboard eraser entirety departs from blackboard 18.
Shell 17 is movably connected on blackboard 18, and shell 17 can move relative to blackboard 18, and can resist moment of torsion and gravity, prevents shell 17 and blackboard 18 to be separated.
Certain above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned citing; the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belong to protection domain of the present utility model.
