Description

静电吸尘式黑板擦
技术领域
本实用新型涉及一种黑板擦,特别是涉及一种静电吸尘式黑板擦,是对现有黑板擦结构的改进,属于文教用品范畴,适宜老师在课堂教学时使用。
背景技术
目前,人们所用的黑板擦均为普通样式:矩形木板上镶嵌一块刷毛体,擦黑板时,粉笔灰四处飞扬,即污染了教室内的环境,又对老师和学生的身体健康有所损害,即便如此,现有的黑板擦也只能抹掉黑板上的粉笔痕迹,还需要湿抹布才能进一步清洁黑板上残留的粉笔灰。
实用新型内容
实用新型的目的在于克服现有技术存在的上述不足,通过对现有黑板擦结构的改进,给出一种静电吸尘式黑板擦,该黑板擦利用静电吸尘原理,防止擦黑板时的粉笔灰四处飞扬,不仅改善了教室内的环境,也对老师和学生的身体健康有益。
本实用新型给出的这种静电吸尘式黑板擦,包括有擦拭面板,擦拭面板的正表面边框中设有擦毛,其特点是所述的擦拭面板正表面的擦毛中混杂有丝绸条,在擦毛正表面的两侧上还对称设有长丝绸条,擦拭面板的背面的边框中还设有一块海棉体,所述的海棉体上还设有保护罩。
与现有技术相比,本实用新型的有益效果是:利用静电吸尘原理,防止擦黑板时的粉笔灰四处飞扬,不仅改善了教室内的环境,也对老师和学生的身体健康有益。
附图说明
附图为本实用新型给出实施例的结构示意图;
图中标号:1.擦拭面板,2.混杂有丝绸条的擦毛,3.海棉体,4.保护罩。
具体实施方式
如图所示,这种静电吸尘式黑板擦,包括有擦拭面板1,擦拭面板1的正表面边框中设有混杂有丝绸条的擦毛2,在擦毛2的正表面的两侧上还对称设有长丝绸条,该擦拭面板1的背面的边框中还设有一块海棉体3,所述的海棉体3上还设有保护罩4。
使用时,先用擦拭面板1正表面边框中的混杂有丝绸条的擦毛2擦去黑板上的粉笔字迹,再用擦拭面板1背面边框中的渗有水份的海棉体3擦去黑板上残留的粉笔灰,由于丝绸条在摩擦中产生的静电,使粉笔粉不再四处飞扬,由于保护罩4的保护,海棉体3中的水份也不会很快流失掉,从而保证了擦黑板的质量。
