Description

一种吸尘黑板擦
技术领域
本实用新型涉及一种教学用具,具体来讲是一种吸尘黑板擦。 
背景技术
在给学生上课时,老师会不时地擦黑板,下课时,值日生同学也要擦黑板,传统的黑板擦多采用硬质的刷毛制成,不但黑板擦试不干净,而且擦下的粉笔末还会落在老师和同学们的手上和身上,尤其在气候干燥时,飞扬的粉尘还会被吸入肺内,由于粉笔的特殊物理性能,这会对身体造成很大的伤害,如粉尘引起的尘肺以及各种急慢性呼吸道疾病,对空气质量的影响以及透发近视等。如果能有一种可防止粉尘飞扬的黑板擦,将会对老师和同学们的身心健康特别有益。 
实用新型内容
本实用新型的目的在于提供一种吸尘黑板擦,该黑板擦能够减少和避免使用时引起的粉尘,有效防止粉尘飞扬对人体造成的危害和对环境的污染。 
本实用新型解决其技术问题所采取的技术方案是:一种吸尘黑板擦,其结构包括由刷毛和底座构成的黑板擦本体,在刷毛与底座之间设置有一活性炭罐,所述的活性炭罐的侧壁均匀设置有多个小孔。 
本实用新型的有益效果是:使用时,手握底座,将刷毛与待擦试的黑板表面相接触,此时移动黑板擦底座,刷毛最先触及黑板上的粉笔字迹,随着黑板擦的移动同时利用活性炭的吸附功能,刷毛擦下的粉尘即刻进入活性炭罐,使用后可定期清洗刷毛和炭罐,以保持清洁;本实用新型解决了传统黑 板擦使用时粉尘飞扬、损害手部皮肤、危害教师和学生身心健康的技术问题。 
附图说明
图1为本实用新型的结构示意图; 
图中:1刷毛,2活性炭罐,3底座,4小孔。 
具体实施方式
如图1所示。一种吸尘黑板擦,其结构包括由刷毛1和底座3构成的黑板擦本体,在刷毛1与底座3之间设置有一活性炭罐2,所述的活性炭罐2的侧壁均匀设置有多个小孔4。 
使用时,手握底座3,将刷毛1与待擦试的黑板表面相接触,此时移动黑板擦底座3,刷毛1最先触及黑板上的粉笔字迹,随着黑板擦的移动同时利用活性炭的吸附功能,刷毛1擦下的粉尘即刻进入活性炭罐2,使用后可定期清洗刷毛1和活性炭罐2,以保持清洁。
