Abstract
A dust absorption blackboard brush is characterized in that the blackboard brush consists of a dust absorption brush mechanism and a dust absorption box; the dust absorption brush mechanism is connected with the dust absorption box by a dust absorption pipe; a motor, a gear set and a roller brush chamber, which are combined into a whole by cones and cone holes are arranged in the housing of the dust absorption brush mechanism; roller brushes are connected by the shafts of gears; a switch and a dust absorption passage are arranged in the housing. The blackboard brush is suitable for teachers and students to erase blackboards. The blackboard brush prevents air in teaching rooms from being polluted by chalk ash, and overcomes the trouble that the teacher and the students are obsessed by chalkash for a long time, which is beneficial to the health of the teacher and the students. The utility model has obvious economic and social benefits.
