Abstract

本实用新型公开了一种减尘黑板擦,由板擦背和毛束组成,所述各组毛束沿同一方向倾斜的固定在板擦背上,毛束之间设有吸尘海绵,所述吸尘海绵固定在板擦背上。采用上述减尘黑板擦,由于毛束与黑板平面是呈倾斜角度接触的,因而粉尘很容易被毛束擦下来,被擦下的粉尘将沿着毛束方向下落到板擦的吸尘海绵上暂时储存,所以该实用新型具有结构简单,成本低廉,有效的控制了粉尘的飞扬,保证了教室的环境卫生,有利于教师和学生的身体健康。

Description

减尘黑板擦
技术领域
本实用新型属于一种教学用具,特别涉及一种减尘黑板擦。
背景技术
众所周知,黑板擦由板擦背和若干毛束组成,毛束垂直固定在板擦背上,当用其擦拭黑板时,毛束与黑板面垂直接触,被擦下的粉笔屑集中在毛束与黑板面之间,并不断下落,使粉尘飞扬,污染课堂环境。
发明内容
本实用新型的目的是提供一种结构简单,成本低,能够明显减轻粉尘飞扬的减尘黑板擦。
为实现上述目的,本实用新型的解决方案是:一种减尘黑板擦,由板擦背和毛束组成,所述各组毛束沿同一方向倾斜的固定在板擦背上,毛束之间设有吸尘海绵,所述吸尘海绵固定在板擦背上。
采用上述减尘黑板擦,由于毛束与黑板平面是呈倾斜角度接触的,因而粉尘很容易被毛束擦下来,被擦下的粉尘将沿着毛束方向下落到板擦的吸尘海绵上暂时储存,所以该实用新型具有结构简单,成本低廉,有效的控制了粉尘的飞扬,保证了教室的环境卫生,有利于教师和学生的身体健康。
附图说明
图1是本实用新型实施例的结构示意图。
具体实施方式
如图1所示,该减尘黑板擦,由板擦背1和毛束2组成,所述各组毛束2沿同一方向倾斜的固定在板擦背1上,毛束2之间设有吸尘海绵3,所述吸尘海绵3固定在板擦背1上。所述毛束与板擦背之间构成一锐角,该锐角的角度一般在45——60度之间。
