when the blackboard 1 is used, the button 7 is pressed to enable the button 7 to slide towards the shell 3, so as to drive the push plate 8 to slide towards the sloping block 9, the sloping block 9 is enabled to push the sliding seat 4 to move towards the opening of the shell 3, so as to push the felt 5 out of the shell 3, when the push plate 8 pushes the sloping block 9 to move, the sliding seat 4 pulls the first transmission belt 15 to move, the first transmission belt 15 drives the first transmission wheel 13 to rotate when moving, the first transmission wheel 13 drives the first rotating shaft 12 to rotate when rotating, the first rotating shaft 12 drives the first bevel gear 20 to rotate, so as to drive the second bevel gear 21 to rotate, the second rotating shaft 19 drives the second transmission wheel 22 to rotate when rotating, the second transmission wheel 22 drives the third transmission wheel 23 and the fourth transmission wheel 24 to rotate through the second transmission belt 25 when rotating, and drives the sliding block 18 to move downwards through the second transmission belt 25, so as to make the sliding rod 17 move downwards, make the closed curtain 6 move downwards gradually, meanwhile, the third driving wheel 23 drives the winding roller 14 to rotate when rotating, the winding roller 14 winds the closed curtain 6 on the winding roller 14 when rotating, thereby realizing the winding of the closed curtain 6, when the push plate 8 moves towards the direction far away from the sloping block 9, the first driving belt 15 moves in reverse direction, thereby driving the first driving wheel 13 to rotate in reverse direction, thereby driving the third driving wheel 23 to rotate in reverse direction through the first rotating shaft 12, the first bevel gear 20, the second bevel gear 21, the second driving wheel 22 and the second driving belt 25, and simultaneously driving the sliding rod 17 to move upwards, thereby making the closed curtain 6 unfold, and closing the opening of the shell 3; when the push plate 8 moves towards the inclined block 9, the first transmission belt 15 is pulled to move under the action of the tensile force of the elastic rope 16, so that the first transmission wheel 13 is driven to rotate, after the first transmission wheel 13 rotates to the extreme position, namely the closed curtain 6 is completely rolled up, the push plate 8 just contacts with the inclined block 9, the push plate 8 continuously moves towards the inclined block 9, the push plate 8 gradually pushes the inclined block 9, so that the felt 5 is driven to move through the sliding seat 4, the felt 5 is moved out of the shell 3, at the moment, along with the sliding of the push plate 8, one section of the first transmission belt 15 close to the push plate 8 is gradually loosened, when the button 7 is released, the sliding seat 4 slides towards the direction far away from the opening under the action of the tension spring 10, so that the felt 5 moves into the shell 3, because the section of the first transmission belt 15 close to the push plate 8 is just in a loosened state, the first transmission belt 15 cannot drive the first transmission wheel 13 to rotate when the push plate 8 starts to move, when the first driving belt 15 is tightened, the felt 5 completely enters the shell 3, and then the first driving belt 15 is driven to move along with the movement of the push plate 8, so that the first driving wheel 13 is driven to rotate, and the closed curtain 6 is driven to close the opening of the shell 3; when the blackboard eraser is inserted into the supporting seat 2, the sealing plate 29 is pushed to rotate under the pushing action of the ejector rod 30, so that the through hole at the bottom end of the dust collection box 28 is opened, the collection box 26 is communicated with the dust collection box 28, chalk dust in the dust collection box 28 slides into the collection box 26, the chalk dust on the felt 5 is shaken off under the vibration action of the vibration motor 27, the felt 5 is cleaned, the chalk dust in the dust collection box 28 can quickly slide into the collection box 26, the piston plate is driven to reciprocate in the piston body through the vibration of the vibration motor, generated gas is blown to the felt through the air outlet and the through hole, dust on the felt is blown off, meanwhile, the circular bulge of the rubber rod rubs in the felt in a reciprocating mode, static electricity is generated, the dust is collected when the felt wipes the blackboard on the outer side, and dust raising is effectively inhibited.
