Abstract

一种环保型黑板擦，属于教学用具，主要解决传统黑板擦使用时的粉尘飞扬的问题。它包括毛刷和基板，毛刷安装在基板的一侧，所述毛刷周围的基板上设有吸尘槽，所述吸尘槽与储尘盒相连通，基板与储尘盒之间设有一吸气泵。使用时，毛刷与黑板相接触，打开吸气泵开关，吸气泵工作，反复擦试黑板，此时黑板上掉落的粉尘通过吸尘槽被吸气泵吸入至储尘盒内，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。

一种环保型黑板擦
技术领域
本发明涉及一种教学用具，具体来讲是一种环保型黑板擦。
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。
发明内容
本发明的目的在于提供一种环保型黑板擦，该黑板擦具有防止和减少粉尘飞扬对人体造成的危害和对环境的污染的功能。
本发明解决其技术问题所采取的技术方案是：一种环保型黑板擦，包括毛刷和基板，毛刷安装在基板的一侧，所述毛刷周围的基板上设有吸尘槽，所述吸尘槽与储尘盒相连通，基板与储尘盒之间设有一吸气泵。
本发明的有益效果是：设有吸气泵，黑板上掉落的粉尘通过吸尘槽被吸气泵吸入至储尘盒内，有效减少擦黑板时粉尘飞扬，有效保障了师生的身体健康和教师的环境。
附图说明
图1为本发明的结构示意图；
图中：1毛刷，2吸尘槽，3基板，4吸气泵，5储尘盒。
具体实施方式
如图1所示。一种环保型黑板擦，包括毛刷1和基板2，毛刷1安装在基板2的一侧，所述毛刷1周围的基板2上设有吸尘槽2，所述吸尘槽2与储尘盒5相连通，基板3与储尘盒5之间设有一吸气泵4。
使用时，毛刷1与黑板相接触，打开吸气泵4开关，吸气泵4工作，反复擦试黑板，此时黑板上掉落的粉尘通过吸尘槽2被吸气泵4吸入至储尘盒5内，避免了擦黑板时粉尘飞扬。
