Description
Technical field
This utility model relates to teaching aid technical field, the device of a kind of easy cleaning blackboard eraser.
Background technology
Blackboard is indispensable educational aid in school eduaction, and teacher uses chalk to write the content of courses on blackboard
Carry out teaching, after class, need the content of chalk-writing on blackboard is wiped to ensure the normal of class blackboard of being abandoned or divorced by one's husband
Use, be blackboard eraser for clearing up the instrument of chalk trace on blackboard.
The blackboard that teaching uses now is the biggest, and after every class gets off, whole blackboard is all letter written with chalk, uses blackboard eraser handle
After font erasing, font powder can glue on the bristle staying blackboard eraser, needs in time the powder bullet on blackboard eraser to be fallen, if
Dispose powder not in time, with powder can drop to human body from bristle, fly upward the most everywhere, absorbed by people, affect ring
Border quality, is detrimental to health.
And when playing font powder, it is typically all with hand-held firmly blackboard eraser, and beat at boss edge, now people can absorb powder
End, powder can fly in air, and, artificially to beat blackboard eraser and clear up, cleaning is not clean, and speed is slow, and efficiency is low.
So this utility model provides a kind of new mode to solve this problem.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of this utility model is just to provide a kind of convenient clear
The device of reason blackboard eraser, effectively solves when clearing up blackboard eraser, and cleaning is clean, and speed is slow, efficiency is low, pollute environment,
The problem absorbed by people.
Its technical scheme solved is that, including clean-up frame, driving means, blackboard eraser, clean-up frame includes frame plate, the end of frame plate
Face is provided with supporting leg, and the centre of frame plate is provided with rectangular through-hole, and relative two sides of rectangular through-hole are provided with groove, driving means bag
Including motor base, motor base is provided with bearing block, and motor base is fixed with motor, and the rotating shaft of motor is worn and penetrated at bearing block
In, the termination of rotating shaft is provided with fixture block, and blackboard eraser includes base plate and bristle, and the back side of base plate is provided with the draw-in groove matched with fixture block,
Constituting fixture block and can be fixed on the structure in draw-in groove, the bottom surface of frame plate has dismountable collecting vessel through screw thread coupling, constitutes motor
Base may be stuck in groove, and blackboard eraser is placed in the structure in collecting vessel.
This utility model structure is ingenious, and compact volume and convenience is not take up space, quickly can carry out the bristle of blackboard eraser clearly
Reason, greatly speeds up cleaning speed and the efficiency of blackboard eraser, and blackboard eraser is difficult to lose, and also ensures that font powder will not pollute ring
Border, also will not be detrimental to health.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Being given by Fig. 1 to Fig. 6, this utility model includes clean-up frame 1, driving means 2, blackboard eraser 3, and clean-up frame 1 includes frame
Plate 4, the bottom surface of frame plate 4 is provided with supporting leg 5, and the centre of frame plate 4 is provided with rectangular through-hole 6, and two sides that rectangular through-hole 6 is relative set
Fluted 7, driving means 2 includes that motor base 8, motor base 8 are provided with bearing block 9, and motor base 8 is fixed with motor
10, the rotating shaft 11 of motor 10 is worn and is penetrated in bearing block 8, and the termination of rotating shaft 11 is provided with fixture block 12, and blackboard eraser 3 includes base plate 14 and brush
Hair 15, the back side of base plate 14 is provided with the draw-in groove 16 matched with fixture block 12, constitutes fixture block 12 and can be fixed on the structure in draw-in groove 16,
The bottom surface of frame plate 4 has dismountable collecting vessel 18 through screw thread 17 coupling, constitutes motor base 8 and may be stuck in groove 7, blackboard eraser
3 are placed in the structure in collecting vessel 18.
When this utility model uses, when carrying out wiping font with blackboard eraser 3, due to blackboard eraser 3 small volume, can exist big
The font powder of amount, is now plugged on the draw-in groove 16 on blackboard eraser 3 base plate 14 in fixture block 12, and fixture block 12 is removable with draw-in groove 16
Unloading connection, as long as the most firmly fixture block 12 can be plugged in draw-in groove 16, equally, as long as slightly exerting oneself, blackboard eraser 3 can be taken off
Come.
Blackboard eraser 3 now has been fixed in rotating shaft 11, then blackboard eraser 3 through rectangular through-hole 6, and motor base 8
The most just it is stuck in groove 7 inside not passed through, collecting vessel 18 is arranged on frame plate 4 through screw thread 17 connection, the most all installations
Complete.
Starting motor 10, motor 10 drive shaft 11 rotates, and rotating shaft 11 drives blackboard eraser 3 to rotate so that brush on blackboard eraser 3
The font powder of hair 15 comes off with centrifugal force, and font powder is inherently simply attached to bristle 15 surface gently, all also
Need not great power powder to be got rid of, got rid of the powder hung and fall in collecting vessel 18, do not pollute the environment, will not be by
Absorption of human body.
And after blackboard eraser 3 has been cleared up, blackboard eraser 3 can be directly placed in rotating shaft 11, it is to avoid blackboard eraser 3 due to
The problem of the least frequent loss.
The structure of clean-up frame 1 is the least, and volume is simply big than blackboard eraser 3 more all can't take up room, motor
10 power can drive blackboard eraser 3 to rotate, and blackboard eraser 3 rotates in collecting vessel 18 can be naturally shed powder, and this practicality is new
Although type structure seems simple, but three combines closely, inseparable, clean-up frame 1 can play work that is fixing and that collect
Replacement can be played by, driving means 2 artificially to beat, it is to avoid powder is absorbed by the body or drops to the effect with human body, black
Blackboard eraser 3 needs driving means 2 to coordinate, and is placed on clean-up frame 1, could constitute a complete technical scheme.
This utility model structure is ingenious, and compact volume and convenience is not take up space, quickly can carry out the bristle of blackboard eraser clearly
Reason, greatly speeds up cleaning speed and the efficiency of blackboard eraser, and blackboard eraser is difficult to lose, and also ensures that font powder will not pollute ring
Border, also will not be detrimental to health.
