Description

一种黑板擦
本实用新型涉及一种黑板擦。
现在使用的黑板擦常常导致粉笔灰到处飞扬,既对人体造成不良影响,又影响环境卫生。
本实用新型的目的就是要解决现有技术中的问题,提供一种卫生的黑板擦。
本实用新型的目的是这样实现的:一种黑板擦,由壳体3和固定在壳体3上的刷毛1组成,在刷毛1外设置有一圈连接在壳体3上的绵毛2,绵毛2与刷毛1之间有间隙,壳体3的底面为圆形。
由于采用在刷毛外围一圈绵毛的结构,所以擦掉的粉笔落在壳体内,不会到处飘浮;又由于壳体底部采用圆形的结构,所以可使擦拭的范围增大。
下面结合附图和实施例对本实用新型作进一步详细说明。
图1为本实用新型的结构示意图。
图2为图1的左视图。
图1兼作摘要附图。
图中:1、刷毛,2、绵毛,3、外壳,4、把手。
如图1,一种黑板擦,由壳体3和固定在壳体3上的刷毛1组成,在刷毛1外设置有一圈连接在壳体3上的绵毛2,绵毛2与刷毛1之间有间隙,壳体3的底面为圆形。
手持把手4擦拭黑板,粉笔灰落在外壳3内,而不至于到处飘浮;将黑板擦轻轻抖一抖,即可将粉笔灰脱落。
