The outer casing, the upper cover and the lower cover are encapsulate and connected on the soleplate for forming a powder collecting box, and the soleplate is provided with a plurality of shaft holes and a plurality of through holes for absorbing powder, and the lower cover is provided with a dust leakage hole, gear shafts have one end arranged in the fixing holes of gear shafts, the other end extends out of shaft holes on the soleplate and is connected with the rotating head for a blackboard wiper, an output shaft of a motor is connected with the driving gear shaft, the driving gear shaft as assembled engages with a plurality of gear shafts one another. The gear shafts as engaged is driven by a motor to perform clockwise and anticlockwise turning, and the rotating head for a blackboard wiper which is connected with gear shafts is driven to perform clockwise and anticlockwise turning, and fans are fixed at the anticlockwise gear shafts at the interval of the gear shafts, fans are fixed at the anticlockwise gear shaft at the interval of the gear shafts, and the fans absorb the dust to the powder collecting box with the dust falling from the dust leakage hole of the lower cover according to gravity for being collected. The utility model has advantages of a simple structure, light weight and good environmental protection effect, and is good for the health of the teachers and students.
Description
(1) technical field
This use is novel to relate to a kind of Electric chalk eraser, and the disposable intelligent electric chalkboard eraser that the writing on the blackboard chalk writing is not subjected to chalk ash pollution again of wiping is specially adapted to impart knowledge to students.
(2) background technology
Under the situation that does not also have to popularize in electronic teaching, the teaching of middle and primary schools is still used chalk writing prolonging, frequently with the manual writing of wiping of blackboard eraser, the chalk dust of wiping descends slowly and lightly everywhere, and chafe has polluted air, have a strong impact on the healthy of teachers and students, especially teacher's long-term work is in the environment of powder ash fouling, dry cough usually, and professional pneumoconiosis is suffered from serious meeting.
(3) summary of the invention
The technical problems to be solved in the utility model provides a kind of can horizontally slipping along the guide rail that is located at the blackboard top and bottom on blackboard surface, wipe the intelligent electric chalkboard eraser of writing on the blackboard chalk writing, exempts the pollution that chalk dust causes.
The technical solution adopted in the utility model is:
The intelligent electric chalkboard eraser comprises shell, upper end cover, bottom end cover, base plate, supporting plate, gear shaft, blackboard eraser swivel head.Shell, upper end cover, the bottom end cover encapsulation is connected on the base plate, form collection powder case, indicator lamp and power switch are housed on its shell, bottom end cover is provided with the Lou open-work of powder ash, base plate is provided with a plurality of axis holes and a plurality of suction powder open-work, the supporting plate of a plurality of fixedly connected gear shaft installing holes is housed in collection powder case, driving gear shaft and a plurality of gear shaft, supporting plate is fixedly connected on the shell, motor is connected on the shell, motor output shaft connects driving gear shaft, driving gear shaft connects the blackboard eraser swivel head, one end of a plurality of gear shafts is assemblied in a plurality of gear shaft installing holes, and be furnished with stage clip and wear plate, and the axis hole that the other end stretches out on the base plate is connected with the blackboard eraser swivel head, and the gear on the driving gear shaft after the assembling and a plurality of gear shaft meshes each other.The driven by motor driving gear shaft rotates, drive and the positive and negative rotation of driving gear shaft meshed gears axle, the a plurality of blackboard eraser swivel head rotating that is connected with gear shaft, fan blade is interval in gear shaft and is fixed on the counter gear axle, constituted the intelligent electric chalkboard eraser, this chalkboard eraser pack into upper rail and lower guideway can move on guide rail during work.
Above-mentioned compression spring sleeve is contained on the interior gear shaft of gear shaft installing hole.
Above-mentioned wear plate is installed in the end of the gear shaft in the gear shaft installing hole.
Above-mentioned upper rail (21) and lower guideway (22) are positioned over the blackboard top and bottom respectively, be fixed on the blackboard frame or on the wall, chalkboard eraser base plate (2) is provided with upper roller (1) and bottom roller (6), upper roller (1) and bottom roller (6) are respectively charged in the guide groove of the guide groove of upper rail (21) and lower guideway (22), and chalkboard eraser can horizontally slip along blackboard surface.
The utility model has the advantages that simple in structure, in light weight, environment protecting is good, helps the healthy of teachers and students.
