Description

粉笔吸尘器
技术领域  本实用新型涉及一种教学用品,尤其是一种吸尘工具。
背景技术  众所周知,粉笔是学校教学中最常用的书写工具。但是,在使用粉笔过程中会有大量的粉笔灰产生,粉笔灰会严重污染空气,更会威胁人体健康。可是,在使用过程中却缺少专用于粉笔的吸尘工具。
发明内容  本实用新型的目的是提供一种操作便利、卫生安全、具备吸尘功能的粉笔吸尘器。
本实用新型包括套筒,在套筒尾端安装圆筒状外壳,在外壳内安装吸尘器;外壳底面大于套筒的筒口面积,在外壳底面开设吸尘口;所述吸尘器与电池、开关串联组成电路,开关设置在外壳顶面。
使用时,使用者将粉笔安插在套筒内,然后用手指夹住套筒控制粉笔。当利用粉笔书写板书时,会有大量的粉笔灰飘落下来,此时闭合电路开关,吸尘器开始工作,将空气和灰尘从外壳底面的吸尘口吸入,达到吸尘目的,减少粉尘污染。
与已有技术相比,本实用新型的有益效果为:设计合理、方便实用、操作简单,在使用粉笔过程中会吸尘粉笔灰,提供卫生的使用条件。
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,包括套筒1,在套筒尾端安装圆筒状外壳2,在外壳内安装吸尘器3;外壳底面大于套筒的筒口面积,在外壳底面开设吸尘口4;所述吸尘器与电池、开关串联组成电路,开关设置在外壳顶面。
