Abstract

一种磁性黑板擦,黑板擦、把手和刷毛,所述黑板擦为内部有一空腔体,静电发生器装于空腔体中,所述黑板擦还安装了开关、粉体盒和电池盒;所述黑板擦外壳上设有软磁铁板,软磁铁板与黑板擦外壳连接为一体。本发明使用时手握黑板擦把手,检查黑板擦各个部分,按动把手上的开关。通电后,会产生静电,将黑板擦在黑板上擦拭,刷毛带静电吸收粉笔灰尘。粉笔灰通过小孔进入粉体盒中,等到粉笔灰满后从表面出口将粉笔灰倒出。及时更换电池,并且在使用前检查底层小孔是否被粉笔灰堵住,及时清理。

Description

一种磁性黑板擦
技术领域
本发明涉及一种文化用品,具体的说是一种磁性黑板擦。
背景技术
现在教室的黑板擦,存在这样的缺点,没有在黑板擦上设置软磁铁板,擦完黑板后没将黑板擦放置在磁性黑板上,而是放置在讲桌上黑板擦上的粉笔灰到处可见,很不卫生,使用也不方便。擦黑板,粉笔灰特别多,黑板擦里的刷毛灰太多,黑板擦不干净,并且会特别难清洗。
发明内容
本发明的目的在于克服现有技术的上述不足而提供一种磁性黑板擦,直接在黑板擦外壳上设置软磁铁板,能为教师擦黑板时省力,而且避免人体吸入粉尘。
本发明的技术方案是:黑板擦、把手和刷毛,所述黑板擦为内部有一空腔体,静电发生器装于空腔体中,所述黑板擦还安装了开关、粉体盒和电池盒;所述黑板擦外壳上设有软磁铁板,软磁铁板与黑板擦外壳连接为一体。
本发明的有益效果在于:使用时手握黑板擦把手,检查黑板擦各个部分,按动把手上的开关。通电后,会产生静电,将黑板擦在黑板上擦拭,刷毛带静电吸收粉笔灰尘。粉笔灰通过小孔进入粉体盒中,等到粉笔灰满后从表面出口将粉笔灰倒出。及时更换电池,并且在使用前检查底层小孔是否被粉笔灰堵住,及时清理。
附图说明
图1是本发明的结构示意图。
具体实施方式
如图1所示,黑板擦1为空心的,安装了静电发生器;所述黑板擦1还安装了开关3、粉体盒5和电池盒6。使用时,手握黑板擦把手2,检查黑板擦各个部分,按动把手2上的开关3。黑板擦1外壳上设有软磁铁板,所述软磁铁板与黑板擦1外壳连接为一体,在黑板擦外壳上设置软磁铁板,其整体设置合理,结构简单,制造成本低廉,使用非常方便实用。通电后,会产生静电 (不会对人体造成伤害 ),将黑板擦在黑板上擦拭,刷毛4带静电吸收粉笔灰尘。粉笔灰通过小孔进入粉体盒5中,等到粉笔灰满后从表面出口将粉笔灰倒出。及时更换电池,并且在使用前检查底层小孔是否被粉笔灰堵住,及时清理。
