The invention discloses an intelligent blackboard, which includes a blackboard body located inside a wall. An inner cavity is formed in the wall, a convex block is arranged at the front end of the inner cavity, and a blackboard penetrating-inserting portion is enclosed by the inner wall of the convex block. Blackboard moving air cylinders capable of pushing the blackboard body to move front and rear are arranged at the rear end of the inner cavity, the blackboard body moves forward to extent into the blackboard interpenetration portion, two baffles which can be driven to move by baffle movement cylinders are arranged on the rear end face of the convex block, the two baffles move up and down and cover the blackboard interpenetration portion when being attached to each other, and two blackboard erasers moving left and right are symmetrically arranged on the left and right sides of the inner cavity. Each blackboard eraser includes an eraser body fixing block and a soft eraser body, arc-shaped extension portions extending backwards are arranged on the left and right sides of the blackboard body, as the soft eraser bodies move towards the middle of the blackboard body, the arc-shaped extension portions are extruded to gradually deform until being attached to the blackboard body, the ends of the soft eraser bodies lean towards the position where the middle of the blackboard body is located, the two soft eraser bodies move to the middle of the blackboard body to be attached to each other, and air suction holes are formed in the bottom of the inner cavity. According to the intelligent blackboard, the functions of writing, wiping, air blowing and dust suction are integrated, and use is convenient and reliable.
