Description

黑板擦
技术领域
本实用新型涉及一种黑板擦。
背景技术
在黑板上用粉笔书写时,普通黑板擦在擦除粉笔书写的文字时,极易使粉笔屑随着黑板擦的移动随气流飞扬,既污染环境,又危害人体健康。特别是对于长期从事教学工作的教师,日积月累,粉尘会在呼吸系统沉积,引发职业病,对于坐在前几排的学生也同样会造成不利影响。
发明内容
本实用新型提供了一种黑板擦,具有磁性,粉尘可以吸附在磁性黑板上。
本实用新型黑板擦通过以下技术方案实现目的:
一种黑板擦,其特征在于,所述的黑板擦有磁铁。
上述的黑板擦,包括壳体,壳体为磁铁,其磁性与黑板的磁性相反。
上述的黑板擦的壳体内有磁铁,且磁性与黑板的磁性相反。
采用本实用新型的黑板擦的优点在于:
具有磁性,能够吸附在磁性黑板上,可防止灰尘的飘落。
附图说明
图1是本实用新型的黑板擦的结构示意图:
图中:1、黑板擦,2、壳体,3、毛毡,4、磁铁。
具体实施方式
如图1所示,一种黑板擦1,包括壳体2及毛毡3,壳体内有磁铁4,其磁性与黑板的磁性相反。这样在使用时,黑板擦就能够吸附在磁性黑板上,可
防止粉笔灰的飘扬。
 本实用新型不花费创造性的劳动,在上述实施例的基础上能够做多种变化,同样能够实现本实用新型的目的。
