Description

一种黑板擦
技术领域:
本实用新型涉及一种教学用具,更具体地说,是涉及一种黑板擦结构的改进。
背景技术:
目前,在课堂教学中所采用的普通黑板擦,存在以下缺点:由于在干燥的状态下除灰,粉笔灰不容易粘到黑板擦的海绵块上,导致黑板擦不净;另外,粉笔灰容易飞入空气中,会被教师吸入肺部,长期频繁地吸入粉笔灰,会直接影响人的身体健康。
实用新型内容:
本实用新型就是针对上述问题,提供一种清洁效果好、有利于人身体健康的黑板擦。
为实现本实用新型的上述目的,本实用新型采用如下技术方案,本实用新型包括壳体,在壳体的下方设置有海绵块,其结构要点是在壳体内部设置有喷水壶体,在壳体的侧方设置有喷水壶体的喷嘴。
本实用新型的有益效果:
1、清洁效果好:
在本实用新型黑板擦的壳体内部设置的喷水壶体,可以方便教师在擦黑板的同时对黑板进行喷水,达到很好的清洁效果;
2、有利于人身体健康:
在使用本实用新型黑板擦擦黑板时喷出的水,使大量粉笔灰都吸附在海绵块上,阻止其飞入空气中、进入人肺部,影响人的身体健康。
附图说明:
图1是本实用新型的结构示意图。
具体实施方式:
本实用新型包括壳体3,在壳体3的下方设置有海绵块1,在壳体3内部设置有喷水壶体2,在壳体3的侧方设置有喷水壶体2的喷嘴4。
