Have cylinder axis 6, the having of front end installation installed in the middle of cylinder 5 drive gear 7a and drive gear 7b, in fan gear 13
It is readily accessible that one end of axle has splined shaft to be inserted directly into one end of fan shaft 11, and having of the above uniform installation of fan shaft 11 is centrifugal
Fan 12, what two inclined-planes of T-shaped upper protecting cover 2 were internally installed has drainage screen 10.
Driving when woollens cylinder 5 is by extraneous frictional force drives gear 7a to rotate, and drives gear 7a to turn clockwise
Time with fan gear 13 shape in an angle and drive the little gear of speed increasing gear group 18a by speed increasing gear group 18a entirety to the right
Mobile, to move to gear wheel just two ends ratcheting with fan gear 13, speed increasing gear group 18a axis just oval with gear-box
The right side in hole 20 combines, and fan gear 13 can be clockwise higher than the number driving gear 7a under the drive of speed increasing gear group 18a
Times rotating speed rotates, and drives gear 7b form an elevation angle with guide gear 19 and drive speed increasing gear group 18b when turning clockwise
Little gear speed increasing gear group 18b entirety is moved right, moves to two ends and the gear-box of speed increasing gear group 18b axis oval
The right side in hole 20 combines, the gear wheel of speed increasing gear group 18b separates with guide gear 19.
Drive when driving gear 7a to rotate counterclockwise when woollens cylinder 5 is by extraneous frictional force and fan gear 13
Form an elevation angle and drive the little gear of speed increasing gear group 18a speed increasing gear group 18a entirety to be moved to the left, move to increase
The two ends of speed gear train 18a axis are combined with the left side of gear-box elliptical aperture 20, gear wheel and the fan tooth of speed increasing gear group 18a
Wheel 13 separation, drives gear 7b in an angle and to drive speed increasing gear group 18b with guide gear 19 shape when rotating counterclockwise
Speed increasing gear group 18b entirety is moved to the left, moves to two ends and the gear-box elliptical aperture of speed increasing gear group 18b axis by little gear
The left side of 20 combines, the gear wheel of speed increasing gear group 18b is ratcheting with guide gear 19 and drives guide gear 19 to revolve counterclockwise
Turning, guide gear 19 simultaneously drives fan gear 13 and rotates higher than the several times rotating speed driving gear 7b clockwise.
Fan gear 13 drives centrifugal fan 12 synchronous rotary, due to dividing plate by fan shaft 11 atwirl simultaneously
14, in dust-separation plate washer 16, T-shaped, space between protecting cover forms the cell of a kind of scroll casing shape, and centrifugal fan 12 is atwirl
Produce centrifugal suction simultaneously, the chalk dust on woollens cylinder 5 is sucked the inside of centrifugal fan 12 from suction port 15, passes through
Centrifugal force by air together with chalk dust from the groove of dust-separation plate washer 16 press to T-shaped the both sides within protecting cover 2, then air from

Detailed description of the invention
Be easy to the instrument using method use of cleaning automatic dust absorption according to the invention described above during, hand-held blackboard eraser is with powder
Wiping back and forth on the blackboard of word, woollens cylinder is at speed increasing gear group, fan gear and the resistance of combined centrifugal fan
Under can only slowly rotate, during rotating, produce certain friction with blackboard the chalk dust on blackboard taken away, woollen is knitted
Thing cylinder turns clockwise by driving the little gear of gear driven speed increasing gear group to rotate counterclockwise, the canine tooth of speed increasing gear group
Take turns and rotate along with little gear synchronous and drive fan gear and centrifugal fan clockwise with higher than the rotating speed driving gear several times
Rotate, by driving the little gear of gear driven speed increasing gear group to turn clockwise, increase when woollens cylinder rotates counterclockwise
Speed gear train gear wheel along with little gear synchronous rotate and drive guide gear to rotate counterclockwise, guide gear drives again
Fan gear and centrifugal fan clockwise to rotate higher than the rotating speed driving gear several times, incompetent woollens cylinder clockwise or
Rotate counterclockwise, centrifugal fan is to rotate higher than the several times rotating speed driving gear clockwise all the time, quickly rotates at centrifugal fan
While can produce centrifugal suction, the chalk dust on rubber weather strip periphery and woollens cylinder is sucked protecting cover in T-shaped
Both sides store, and air then flows out from air-vent, when chalk dust stores some, by prolonging of rectangle housing two ends
Stretching hook and smash pressing taking-up from hook, in T-shaped, protecting cover just can separate with rectangle housing, with brush by dust-separation plate washer and filtration
Chalk dust inside net is removed, if the chalk dust on woollens cylinder and drainage screen too much can dry in the air directly with water flushing
On dry bonnet, in T-shaped, protecting cover just can be continuing with.
