Description

电动吸尘黑板擦
技术领域:
本实用新型是涉及黑板擦结构的改进。
背景技术:
现在绝大多数学校都使用普通黑板擦,由于粉尘大,长时间使用,不仅危害师生们身体健康,而且也污染了环境。
实用新型内容:
本实用新型就是针对上述问题,提供一种无粉尘的电动吸尘黑板擦。
本实用新型采用如下技术方案:本实用新型包括风机,风机是由电机上的叶片、外有壳体组成,其结构要点是风机的壳体外设置密封盒,密封盒外为多孔毛毡,密封盒内设置有可拆卸的粉尘盒,密封盒与风机的壳体之间设置过滤网。
本实用新型的有益效果:
1、无粉尘:
由于本实用新型风机的壳体外设置密封盒,密封盒外为多孔毛毡,密封盒内设置有可拆卸的粉尘盒,密封盒与风机的壳体之间设置过滤网;本实用新型的叶片旋转,就将通过多孔毛毡进入的粉尘,经过过滤网的阻挡进入到密封盒内的粉尘盒中,确保粉笔的粉尘不再污染周围环境;
2、结构简单:
本实用新型的构件少,且形体简单,易于制作,易于推广普及。
附图说明:
图1是本实用新型的结构示意图;
图2是图1的左视图;
图3是图1的A-A剖视图。
具体实施方式:
本实用新型包括风机9,风机9是由电机7上的叶片8、外有壳体6组成,风机9的壳体6外设置密封盒2,密封盒2外为多孔毛毡1,密封盒2内设置有可拆卸的粉尘盒3,密封盒2与风机9的壳体6之间设置过滤网5。
使用时,通过开关4同电源相连,风机9的叶片8就可进行吸尘工作;当通过多孔毛毡1吸入到密封盒2内的粉尘较多时,就可将粉尘盒3拉出来倾倒;然后,再将粉尘盒3送回密封盒2内,继续收集粉尘工作。
