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,粉笔末就会纷纷落在老师和同学们的手上和身上,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,粉尘对眼睛、耳、皮肤的伤害,还能诱发其它疾病,对空气质量的影响以及对近视的影响等等。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,该黑板擦能够吸收黑板擦使用时引起的粉尘,有效防止和减少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间题所采取的技术方案是:一种吸尘黑板擦,包括黑板擦本体,其特征是,所述的黑板擦本体由壳体、刷毛和微型吸尘器构成,吸尘器安装在壳体内,刷毛均匀分布在壳体的上表面,在刷毛根部的壳体空隙中设有吸尘口,吸尘口内设有吸尘器的叶片,在壳体外侧设有吸尘器的控制开关。
本实用新型的有益效果是:吸尘器能够吸收擦黑板时产生的粉尘,解决了擦黑板时粉尘飞扬、危害教师和学生身心健康的问题。
附图说明
图1为本实用新型的结构示意图;
图中:1壳体,2刷毛,3吸尘器,4吸尘口,5控制开关。
具体实施方式
如图1所示。一种吸尘黑板擦,包括黑板擦本体,所述的黑板擦本体由壳体1、刷毛2和微型吸尘器3构成,吸尘器3安装在壳体1内,刷毛2均匀分布在壳体1的上表面,在刷毛2根部的壳体空隙中设有吸尘口4,吸尘口4内设有吸尘器3的叶片,在壳体1外侧设有吸尘器3的控制开关5。
使用时,打开控制开关5,吸尘器3启动工作,在黑板工作平面内左右或上下方向移动黑板擦本体,此时擦下的粉尘被旋转的叶片吸入壳体1内。本实用新型有效解决了擦黑板时粉尘飞扬、危害教师和学生身心健康的问题。
