Description

一种黑板擦
技术领域
本实用新型涉及一种黑板擦,特别是涉及一种能吸粉尘的黑板擦。
背景技术
公知的黑板擦可起到从黑板上擦去粉尘的作用,而无法解决粉尘污染的问题。粉笔的主要成份是氢氧化钙等化学物质,对人体有害。学生则至少9年、教师则要30年长期吸入粉尘对学生和教师的身心健康非常不利,同时粉尘飞扬很不卫生,擦不干净再写对学生视力不利。现在使用的黑板擦和无尘粉笔等都不能彻底解决这一问题。
发明内容
本实用新型的目的是提供一种改进的黑板擦,它能起到吸附粉尘,擦的干净的作用,从而解决粉尘对环境的污染和对人体的危害。
采用的技术方案是:
一种黑板擦,包括毛刷、风筒、电机、叶轮、电池组、粉尘袋,毛刷固设在风筒的前端口处,电机装设在风筒内,叶轮装设在电机轴的前端,风筒上固定连接有把柄,电源电池装设在把柄内,电源电池通过导线与风筒内的电机相连接,风筒的后端装设有粉尘袋。
本实用新型具有结构简单、使用方便、吸尘效果好等优点,能够使教师工作环境更加环保,避免教师因常吸入粉尘而患上咽炎或肺病。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
一种黑板擦,包括毛刷1、风筒2、电机3、叶轮4、电池组5、粉尘袋6,毛刷1固设在风筒2的前端口处,电机3装设在风筒2内,叶轮4装设在电机轴的前端,风筒2上固定连接有把柄7,电池组5装设在把柄7内,把柄7上安装有开关8。电池组5通过导线与风筒2内的电机3相连接,风筒2的后端装设有粉尘袋6。
