Wiping body 21 comprises a cylindrical cavernous body, and the center of cylindrical cavernous body is provided with runs through through hole, runs through and in through hole, is fixedly installed a pipe;
In the pipe of wiping body 21, be provided with unilateral bearing, the unilateral bearing rotation direction of two wiping bodies 21 is contrary, and two wiping bodies 21 are inwardly rotated; Be that left wiping body 21 can only turn clockwise under the effect of its unilateral bearing, and right wiping body 21 can only be rotated counterclockwise under the effect of its unilateral bearing;
The unilateral bearing of wiping body 21 is arranged in movable axis bearing 24, and wiping body 21 is connected and fixed axle 30 by its movable axis bearing 24, and the two ends of fixed axis 30 are fixedly connected with respectively forward and backward holder 22,23;
The coaxial sealed support 25 that connects of movable axis bearing 24, movable axis bearing 24 and sealed support 25 are embedded in forward and backward holder 22,23;
The outside of two sealed supports 25 of same wiping body 21 is connected to floating seal stake body by roller rods 251, is arranged with sealed roller 28 in roller rods 251; Sealed roller 28 is positioned at the outside of wiping body 21; The skin of sealed roller 28 is enclosed with soft rubber, to reduce noise;
The below of two wiping bodies 21 is respectively arranged with dust removal brush 26; Dust removal brush 26 is fixedly installed in dust removal brush rotating shaft, and dust removal brush rotating shaft connects dust removal brush 26 by elastomer; The two ends of dust removal brush rotating shaft are flexibly connected with forward and backward holder 22,23, and dust removal brush rotating shaft can be rotated with respect to forward and backward holder 22,23; Elastomer can be controlled the angle of dust removal brush 26, makes dust removal brush 26 lean against all the time the outer surface of wiping body 21;
The outside, below of two wiping bodies 21 is also provided with dust block board 27; Dust block board 27 is positioned at the outside of dust removal brush 26; Dust block board 27 is fixedly installed in dust block board rotating shaft, and dust block board rotating shaft connects dust block board 27 by another elastomer; The two ends of dust block board rotating shaft are flexibly connected with forward and backward holder 22,23, and dust block board rotating shaft can be rotated with respect to forward and backward holder 22,23; Dust block board 27 is provided with pressing plate head 271 with the contact site of wiping body 21, and pressing plate head 271 comprises one deck tweed, and the surface of tweed is provided with the plastic layer that one deck is smooth; Elastomer can be controlled the angle of dust block board 27, and the pressing plate head 271 of dust block board 27 is pressed on wiping body 21 all the time, even if wearing and tearing occur wiping body 21, also still can be pressed on wiping body 21;
Elastomer can be torsion spring, spring or extension spring;
As shown in Figure 5, the inner side of sealed support 25 is provided with handle 252, and the corresponding site of movable axis bearing 24 is provided with fixture block 242; When wiping body 21 forwards stressed (being subject to clockwise power as right wiping body 21 is subject to anticlockwise power or left wiping examination body 21) or two select one (or being that the direction that unilateral bearing can move is continuously positive direction), drive its unilateral bearing to rotate, 25 pulling force that are subject to back-moving spring 31 of sealed support, movable axis bearing 24 keeps relative stationary state with sealed support 25; When wiping body 21 reverse when stressed, its unilateral bearing is motionless, movable axis bearing 24 can be with respect to fixed axis 30 reverse rotation one angles under the effect of this opposite force, the fixture block 242 of movable axis bearing 24 props up the handle 252 of sealed support 25, thereby the sealed roller 28 of this wiping body 21 is depressed, as shown in Figure 6;
As shown in Figure 7, Figure 8, rear holder 23 is provided with hinge; Back-end sealing support 25(is positioned at the sealed support 25 of wiping body 21 rear ends) inner side by back-moving spring 31, connect after holder 23, stretch out from housing 1 in the outside of back-end sealing support 25; Back-end sealing support 25 matches with one end of hinge pole, and the other end of hinge pole is fixedly connected with the hinge of rear holder 23; Back-end sealing support 25 can be controlled the hinge folding of rear holder 23; When back-end sealing support 25 turns to certain stroke, one end of back-end sealing support 25 contact hinge poles is also pressed down, and drives hinge to rotate an angle, thereby hinge is opened;
While erasing the board, sealed roller 28 presses down, and after back-end sealing support 25 rotates, by hinge pole, drives hinge to open, and now chalk dust can fall in ash-storing bin 4 smoothly; While stopping erasing the board, sealed roller 28 is not subject to external force, and back-moving spring 31 resets back-end sealing support 25, and hinge is closed;
Between the inwall of floating seal stake body and housing 1, be provided with a sealing strip 29, the outside of sealed support 25 and the sealing between housing 1 inwall while producing from housing 1 for the outside at back-end sealing support 25, thus dust is sealed in housing 1; Sealing strip 29 adopts soft material;
When the chalk dust in ash-storing bin 4 is filled, open ash-storing bin lid 3 and poured out.。
Operation principle of the present utility model is as follows:
By being pressed on blackboard, housing 1 left and right is swung back and forth two wiping bodies 21, under the effect of unilateral bearing, two wiping bodies 21 are alternately made unidirectional rotary motion; During wiping left (housing 1 moves from right to left), left wiping body 21 is clockwise Free-rolling under the effect of its unilateral bearing, first letter written with chalk surface one deck dust is taken away; Meanwhile, right wiping body 21 cannot be rotated with respect to movable axis bearing 24 by the constraint of its unilateral bearing, more remaining letter written with chalk is wiped clean; Under the effect of blackboard frictional force, right wiping body 21 and unilateral bearing and movable axis bearing 24 are whole can be around fixed axis 30 reverse rotation one fixed angles, meanwhile movable axis bearing 24 drives sealed support 25 to rotate to an angle around fixed axis 30, thereby right side sealed roller 28 is depressed, right side sealed roller 28 departs from blackboard panel, thereby avoid after right wiping body 21 wiped clean blackboards, sealed roller 28 pairs of blackboard panels in right side cause secondary pollution;
Left wiping body 21 is brought dust in housing 1 in the process of rolling, and when the dust removal brush 26 through housing 1 inwall, 26 pairs of left wiping body 21 outer surfaces of dust removal brush are cleared up, and left wiping body 21 produces after being cleaned down by dust removal brush 26 again;
Dust removal brush 26, when brushing the dust of wiping body 21 outer surfaces, can evoke dust and fly upward, and the dust block board 27 that is now positioned at dust removal brush 26 outsides first keeps off and falls major part, then by left side sealed roller 28, dust is completely enclosed within housing 1;
When wiping motion, when namely back-end sealing support 25 is depressed by movable axis bearing 24, back-end sealing support 25 drives hinge to open by hinge pole, makes to be brushed the dust falling and drops in ash-storing bin 4;
During wiping to the right, in like manner, right wiping body 21 counterclockwise Free-rolling under the effect of its unilateral bearing, first takes away letter written with chalk surface one deck dust (also cleaned last time static wipe the chalk dust that rear surface is left over) simultaneously; And left wiping body 21 cannot be rotated by the constraint of its unilateral bearing, so remaining chalk dust is cleaned, ash is being collected in ash-storing bin 4 simultaneously; Alternate cycles like this.
