Abstract

一种黑板擦,主要包括盒体式外壳以及清洁布,清洁布安装在外壳内部,且清洁布底面探出外壳底边开口,围绕外壳外表面密集粘贴多束塑料软刷毛,软刷毛底端与外壳底边齐平,软刷毛根部与外壳连接端形成40度夹角。本实用新型具有操作简便、结构合理、方便实用、卫生便捷等优点。

Description

黑板擦
技术领域  本实用新型涉及一种教学用品。
背景技术  目前学校教学中,黑板与粉笔是教师向学生传达信息的最主要工具,而黑板擦依旧是人们最常用的黑板擦拭用具。但是,曾有和现有的黑板擦结构过于单一,全部采用外壳和清洁布粘贴连接方式组合而成,在擦拭过程中,清洁布与粉笔字摩擦后会造成大量粉尘污染,严重危害师生身体健康,而目前的黑板擦根本无法避免此类问题。
发明内容  本实用新型的目的是提供一种通过静电作用来吸附灰尘的黑板擦。
本实用新型主要包括盒体式外壳以及清洁布,清洁布安装在外壳内部,且清洁布底面探出外壳底边开口,围绕外壳外表面密集粘贴多束塑料软刷毛,软刷毛底端与外壳底边齐平,软刷毛根部与外壳连接端形成40度夹角。
擦拭黑板时,使用者依然握住外壳,利用清洁布擦拭粉笔字,但是在擦拭过程中,外壳周围的软刷毛与黑板不断摩擦,从而在刷毛表面形成静电,当清洁布擦拭粉笔字而产生粉尘时,这些刷毛便会通过静电作用把微小的粉尘吸附在自身表面,降低粉尘污染。另外,粉尘也会被限制在外壳和刷毛之间,进一步降低粉尘污染。
与已有技术相比,本实用新型的有益效果为:操作简便、结构合理、方便实用、卫生便捷,抑制粉尘飞舞,降低粉尘污染,保护使用者身体健康。
附图说明  图1为本实用新型的立体结构简图。
具体实施方式  在图1所示的本实用新型的立体结构简图中,主要包括盒体式外壳1以及清洁布2,清洁布安装在外壳内部,且清洁布底面探出外壳底边开口,围绕外壳外表面密集粘贴多束塑料软刷毛3,软刷毛底端与外壳底边齐平,软刷毛根部与外壳连接端形成40度夹角。
