Description

黑板擦
技术领域:本实用新型属教学用具技术领域,具体涉及一种能防尘的黑板擦。
背景技术:目前,教学用的黑板擦大多是毛毡式的,结构单简,使用时,擦下的粉笔灰尘到处飞扬,其缺点是,一是造成环境污染,二是对师生的身体健康造成一定的伤害。
发明内容:本实用新型的目的是提供一种结构简单,具有防尘功能的,保证师生身体健康的环保的黑板擦。
本实用新型的技术方案是:一种黑板擦,由板体和与其活动连接的刷毛组成,其特征是:在板体一侧设有储水盒,在储水盒和刷毛之间的板体上的槽里设有吸水海绵,与吸水海绵相接的储水盒的侧面设有多个出水孔。其中,所述的板体和刷毛是通过榫条和榫口活动连接的。
由于采用上述技术方案,使用时,向储水盒中加入适量的水,通过出水孔流到吸水海绵里,再渗到刷毛上,不会造成刷毛上的水过多,由于刷毛是湿润的,擦下的粉尘不会到处飞扬,再者刷毛与板体是活动连接的,需要更换时拆下即可,可节省材料,因而具有结构简单,具有防尘功能的,保证师生身体健康的环保的优点。
附图说明:以下结合附图和具体实施例来对本实用新型的技术方案做进一步详细说明。
附图是本实用新型的结构示意图。
具体实施方式:参考附图,一种黑板擦,由板体1和与其活动连接的刷毛2组成,在板体1一侧设有储水盒3,在储水盒3和刷毛2之间的板体1上的槽里设有吸水海绵4,与吸水海绵4相接的储水盒3的侧面设有多个出水孔5,为了拆卸更换方便,所述的板体1和刷毛2是通过榫条6和榫口7活动连接的。
