Description

一种吸尘黑板擦
本实用新型涉及教具,具体是一种清除粉笔粉尘的吸尘黑板擦。
现在使用的黑板擦为带有毛毡的板式结构,在擦掉黑板上的粉笔字时,使所有的粉笔末四处飞扬,悬浮在教室内的粉尘久久不落。从小学一直到大学,粉笔尘埃长时间地顺呼吸道大量进入师生们的体内,严重地危害着师生们的身体健康,长期以来,人们对粉笔粉尘又无可奈何。
为了克服上述不足,本实用新型的目的是提供一种能边擦黑板边吸除粉笔粉尘的吸尘黑板擦。
本实用新型的目的是这样实现的:由毛毡、毡座、滤袋、外壳、风机和护罩组成,所述毛毡点对称式固定在有中心孔的圆形毡座上,毡座周边压住滤袋的周边后与外壳紧固,外壳和护罩之间装有带电源线的风机。
本实用新型具有结构简单,吸尘效果好,成本低,操作简单,使用方便等优点。
附图说明:
图1为本实用新型结构示意图。
图2为图1中A-A剖视图。
下面结合附图对本实用新型结构及其工作原理作进一步详细说明。
如图1、2所示,由毛毡1、毡座2、滤袋3、外壳4、风机5和护罩6组成,其中条状毛毡1点对称式固定在有中心孔的圆形毡座2上,毡座2周边压住袋状滤袋3的周边后用螺钉与外壳4紧固,外壳4和护罩6之间装有带电源线的风机5用螺钉紧固,整体形成一个中间带有过滤网的封闭结构。
本实用新型的工作原理如下:
擦黑板时,条状毛毡1在黑板面7上平动磨擦,同时启动风机5,旋转的风机5在滤袋3的右侧形成负压,使带有粉尘的气流从毛毡1、黑板面及毡座2形成的封闭通道,全部经毡座2的中心孔进入滤袋3进行过滤,净化后的空气经风机5内空间,从网状护罩6流出,这样,不等粉笔末扩散到空气中,便被彻底吸入滤袋3中全部滤掉,杜绝了粉笔粉尘在教室内长时间漂浮的恶劣环境发生,将师生们从弥漫的粉尘中解放出来,保证了师生们的身体健康。
