Amenity Design of Blackboard Eraser

Abstract:

According to the problem that chalks will create dust, coming up with the idea of electronic blackboard erasers. When wool felt wiping off the writing, micro-motor drives fan to rotate. It eliminates air and form a great pressure to outside, dirt and dust are drawn into the machine by suction. Through filtering, dusts will be collected into a special dust collector. After testing, more than 95% of dusts can be drawn into electronic blackboard eraser. It has a powerful ability to remove dusts.
