[0002] In the existing teaching, chalk etc. are generally placed in the chalk groove of the blackboard or placed in the chalk box of the podium. The existing chalk box has a simple structure, and the chalk is placed in an ordinary box, so that the dust of the chalk is easy to fall off. When it falls on the table or the ground, it is easy to fly up when the fan is turned on or the wind is relatively strong, and it is easy to affect the health of people if inhaled. Therefore, it is very troublesome to deal with the chalk dust in time.
