Beneficial effect
The blackboard cleaning device of the utility model can all free teachers and students from erasing the board, and it is effective to promote classroom instruction
Time, erasing chalk writing is more convenient, and it is possible to prevente effectively from dust drifts, convenient for the concentration and collection of dust, more
For environmental protection, be conducive to teachers and students' health.
(1) since blackboard eraser can cover blackboard height, Wiper motor back and forth movement can drive blackboard eraser mechanism to pass through in the horizontal direction
Entire blackboard is crossed, therefore, entire blackboard can disposably be wiped by the side-to-side movement of blackboard eraser mechanism, with the phase that erases the board by hand
Than greatly improving the efficiency to erase the board.
(2) when erasing the board, the mobile strip blackboard eraser of one direction, the chalk dust under wiping will be compressed in the strip blackboard eraser direction of motion
Leading edge and blackboard between.By dust-proof guard, drifting for dust can be effectively prevented, so that manually erasing the board causes dust to fly
The phenomenon that raising greatly reduces.
(3) cooperation of idler wheel and sliding slot ensures that whole device primary friction power during erasing the board is blackboard and strip
Frictional force between blackboard eraser, the force of rolling friction between idler wheel and sliding slot can be ignored.
(4) blackboard eraser strut is equipped with sliding slot in one end of blackboard opposite to each other, wherein by the idler wheel merging on drive rod, can will be former
The Wiper motor of this fan shape moving is converted into the horizontal movement of blackboard eraser mechanism, allows blackboard eraser that can clip all areas of blackboard.
(5) in the preferred embodiment, the top of upper horizontal guide rail and the lower part of lower horizontal guide rail all have sliding slot, can be with
Wherein by the idler wheel merging in blackboard eraser mechanism.Since blackboard eraser strut is rigidity, during ensure that strip blackboard eraser side-to-side movement
It is unlikely to be swung left and right.
(6) blackboard eraser mechanism lower end is equipped with and sweeps dust brush, and in blackboard eraser side-to-side movement, blackboard eraser clears up blackboard surface, and dust is fallen
The dust brush in dust collection slot is entered in dust collecting box by dust brush after dust collection slot, it can be by dust collecting box
Plate conveniently by dust collecting box chalk dust export.Under normal condition, at the plate of dust collecting box bottom
In closed state, dust can be collected；When dust collecting box needs to clear up, by the outside pull of plate, dust will be made in gravity
It is fallen under, convenient for the processing of dust.
(7) it is driven due to the utility model using Wiper motor, the switch of Wiper motor is convenient for being set as being remotely controlled.It attends class
When wipe blackboard if necessary, teacher dais away from keyboard, concern student can learn situation simultaneously.
(8) since blackboard eraser is generally made with more soft cloth, certain consumption is certainly existed in use, and
And be to consume most fast in whole device, therefore the utility model sets detachable for strip blackboard eraser position, can allow entire
The service life is longer for mechanism.
(9) in general, teacher needs to carry out writing on the blackboard close to blackboard.Motor is placed in above blackboard, can avoid teacher's plate
It collides with during book, guarantees the safety of teacher and student, can also be improved and be set using the service life.
(10) the utility model is equally applicable to the wiping of blank.
