Description

一种电动吸尘黑板擦,属教学用品范畴。
现教学用品中所用的黑板擦是由毛刷和毛刷固定板等组成。擦黑板时需用力摩擦,粉尘飞扬,既不卫生又危害身心健康。
本实用新型的目的在于提供一种既不用力又能吸收粉尘的小型便携式电动吸尘黑板擦。
本实用新型的方案这样实现:
一微型直流电机带动叶轮转动,叶轮上又装有带毛刷的转盘,毛刷与黑板摩擦,擦净黑板。擦下来的粉尘被旋转的叶轮吸入机内,然后被叶轮沿切线方向甩向贮尘盒内。擦完黑板后可拆下贮尘盒,清除粉尘。
下面通过附图对本实用新型作进一步说明:
图1是本实用新型的结构示意图。
图2是本实用新型的毛刷按装示意图。
1直流电机、2叶轮、3转盘、4毛刷、5外壳、6贮尘盒、7过虑膜、8电池、9开关。
本结构是由直流电机1、叶轮2、外壳5、转盘3、毛刷4、贮尘盒6、过虑膜7等组成。直流电机1装在外壳5内。叶轮2装在直流电机1的轴上,并通过螺纹与转盘3相连,毛刷4装在转盘3上。贮尘盒6与外壳5的伸出端套在一起共同组成把手。过虑膜7装在贮尘盒6内。贮尘盒底部开有通风孔。工作时装在外壳5上的电池8通过开关9接通电机电源,电机1高速旋转。电机1带动叶轮2和转盘3旋转,转盘3上的毛刷4呈数条线状,毛刷安装线沿径向方向向旋转方向倾斜。毛刷4与黑板摩擦擦净黑板。叶轮3高速旋转时其中心形成真空,将擦下来的粉尘吸进来,并在叶轮3作用下将粉尘沿切线方向甩向贮尘盒6。空气通过过虑膜7和贮尘盒6底部的通风孔排出机外。擦完黑板后,拆下贮尘盒6清除粉尘。
