Abstract

The invention discloses a dust absorption spray type blackboard eraser. The dust absorption spray type blackboard eraser is characterized in that one inner side surface of a shell of an erasing surface of the blackboard eraser is provided with a spraying chamber and a dust storage chamber which are fixedly connected, wherein the spraying chamber is next to the shell of the erasing surface of the blackboard eraser, dust absorption ports in the outer surface of the shell of the erasing surface of the blackboard eraser and hair brushes are crosswise distributed, a dust absorption fan and a dust absorption motor are arranged in the dust storage chamber, and when the hair brushes are used for erasing a blackboard, the dust absorption motor receives signals and begins to rotate to drive the dust absorption fan to rotate, so that dust erased off from the blackboard is absorbed into the dust storage chamber through the dust absorption ports; at least a nozzle is arranged in the spraying chamber, the nozzle, a water storage tank and a pressure-sensitive sensor form a sprayer, when the blackboard is not erased cleanly, a user applies an external force to the blackboard eraser, so that the pressure-sensitive sensor receives signals and further controls the nozzle to spray out water mist from the water storage tank for wetting the blackboard, and then the wetted blackboard is erased. The dust absorption spray type blackboard eraser has the advantages of good dust removal effect, reducing the chalk dust suction volume of teachers and students, cleanly erasing the blackboard and improving the learning efficiency of the students in a classroom.
