Abstract

一种静电吸微尘黑板刷实用于吸附擦黑板时的微尘。教室用的黑板擦，一用到处是微尘，影响师生身体健康。该静电吸微尘黑板刷的设计是由外壳，电源，电板及毛刷构成，其中一块电板布满小孔及毛刷。电板通过电源形成静电场，毛刷擦掉的微尘由于静电场的作用通过小孔吸附于静电场（外壳）里。

Description

静电吸微尘黑板刷
技术领域
本实用新型实涉及一种用于教学的设备，具体涉及一种静电吸微尘黑板刷。
背景技术
 教室用的黑板擦，一用到处是微尘，影响师生身体健康。
实用新型内容
 为了克服教室用的黑板擦，一用到处是微尘，影响老师与学生健康等问题，本实用新型提供一种静电吸微尘黑板刷。该静电吸微尘黑板刷的设计是由外壳，电源，电板及毛刷构成，其中一块电板布满小孔及毛刷。电板通过电源形成静电场，毛刷擦掉的微尘由于静电场的作用通过小孔吸附于静电场（外壳）里，如图所示。本实用新型的有益效果是，结构简单，使用过程中无微尘飞扬，效果好。
附图说明
图1为静电吸微尘黑板刷的结构示意图：
其中1是外壳，2是电源，3是电板，4是小孔，5是毛刷。
具体实施方式
 图1中，用绝缘做外壳（1），外壳（1）内装置电源（2），两块金属电板（3），其中的一块金属电板（3）上加工布满小孔（4）并装置上毛刷（5）。
