Abstract
The utility model relates to an environmental protective blackboard eraser, comprising a blackboard eraser 1, an outer frame 2, an electric fan 3, a guide pipe 4, a switch 5, a dust-collected barrel 6, a filter screen 7 and a handle 8. The utility model adopts the structure that the outer frame is provided with the electric fan and connected with the dust-collected barrel through the guide pipe; the bottom of the dust-collected barrel is provided with the filter screen; the outer frame is also provided with the handle and the switch. Owing to the structure, erased dust is absorbed into a dust-collected bottle with the wind of the electric fan blades so that the dust can not scatter around on the air and can be filtered by a sponge at the dust-collected bottle to improve the air quality and keep clean, and therefore, the dust can not fly around. The dust-collected bottle with filled dust can be demounted to process the dust and changing a surface is very convenient just to be extracted and changed without changing the main body of the blackboard eraser. The utility model has reasonable design, easy use and generalization application.
Description
Technical field:
The utility model relates to a kind of realia, particularly a kind of environment-friendly dust-proof eraser.
