Aerodynamic blackboard eraser

The invention discloses an aerodynamic blackboard eraser. The aerodynamic blackboard eraser comprises a dust collecting mechanism and a dust storage mechanism; the dust collecting mechanism partiallycommunicates with the dust storage mechanism, wherein the dust collecting mechanism comprises a dustproof cover and a hair roller which is capable of rolling; the dustproof cover can be used for covering a part of the hair roller; the dust storage mechanism communicates with the dustproof cover and the communication position is provided with a dust scraping plate; and the dust storage mechanism atleast comprises a dust sucking unit and a dust storage unit. The aerodynamic blackboard eraser realizes high dust collection efficiency in use and is also simple in structure, easy to clean and longin service life. 本发明公开了种空气动力学黑板擦，所述空气动力学黑板擦包括除尘机构和储尘机构，所述除尘机构与所述储尘机构之间部分连通；其中，所述除尘机构包括防尘罩和能够滚动的毛滚轮，所述防尘罩能够罩合部分所述毛滚轮；所述储尘机构与所述防尘罩连通且所述连通处设置有刮灰板，储尘机构至少包括吸尘单元和灰尘储存单元。该空气动力学黑板擦在使用过程中除尘效率高，且该空气动力学黑板擦的结构简单、易于清洁使用寿命长。
