The working principle is that when the blackboard 3 is used, chalk rubs against the blackboard 3 to generate dust which floats in the air, and when the surface of the left projection cloth 2 has no electrostatic force, the floating dust can not be attracted.

When static electricity is generated on the surface of the projection cloth 2, the electrostatic force attracts the electrostatic plate 5 inside the slide 4, the electrostatic plate 5 is attracted to move to the left, the left pressure-sensitive switch 7 is pressed, so that the motor controlling the back suction fan of the suction plate 10 rotates, meanwhile, the static plate 5 drives the driven rod 8 to synchronously move through the linkage rod 6, the blocking plate 9 at the bottom of the driven rod 8 slides on the surface of the air suction plate 10, air leakage holes formed in the surface of the blocking plate 9 are gradually overlapped with air suction holes formed in the surface of the air suction plate 10, further, the air suction holes on the surface of the air suction plate 10 are released, the air suction fan inside the air suction holes rotates along with the motor, the generated suction force sucks the dust which passes through the space between the projection cloth 2 and the blackboard 3 into the air suction plate 10, the contact between the dust and the projection cloth 2 is effectively blocked, thereby achieving the effect of preventing the projection cloth 2 from absorbing the dust scattered by the blackboard 3 when the projection cloth 2 generates static electricity.

When the surface of the projection cloth 2 generates static electricity, because the projection cloth 2 and the electrostatic plate 5 can generate mutual attraction, the projection cloth 2 can become folded, at the moment, because the bearing of the control rotating wheel 16 and the motor controlled by the pressure switch 7 are connected through a coupler, the rotating wheel 16 rotates, the rotating rod 17 on the surface is thrown towards the direction far away from the wheel center, the arc plate 14 is pushed upwards through the roller 18 gradually, and then the iron block 13 at the top of the arc plate 14 is driven to be close to the magnetic plate 12 above, so that the magnetic plate 12 and the iron block 13 reach mutual attraction points, under the action of magnetic force, the magnetic plate 12 pulls the scroll 11 downwards, the scroll 11 is pulled to the projection cloth 2, and therefore when the static electricity appears on the surface of the projection cloth 2, the effect that the fold occurs to the projection cloth 2 is prevented.
