技术领域
本实用新型涉及一种教学用具,具体的说是一种吸尘黑板擦。
背景技术
传统的黑板擦弊端很多,最大的问题是将擦掉的粉笔灰扬起,最后散落到师生的头上、衣服上,污染教室空气,更严重的是被人体吸入引发各种疾病。
实用新型内容
本实用新型的目的是解决擦黑板时粉笔灰扬起污染空气的问题,提供一种吸尘黑板擦,吸取擦黑板时扬起的粉笔灰,清洁教室教学环境。
本实用新型采用的技术方案是:一种吸尘黑板擦,包括刷体和刷毛,其特征在于:所述刷体的刷毛面上开设有吸尘孔,刷体内设有微型吸尘器,微型吸尘器和集尘盒相连接,在集尘盒的下部设有卸灰口,在集尘盒的侧面设有观察窗口。
本实用新型效果是:在擦黑板的同时吸走粉笔灰,避免四散飘扬,净化了教室的教学环境,促进了师生的身心健康,提高了师生的教学和学习效率;观察窗口可观察集尘盒的情况,集尘盒装满后还可清空粉尘,便于使用。
附图说明
图1为本实用新型的整体结构示意图。
图中1为刷体,2为刷毛,3为吸尘孔,4为微型吸尘器,5为卸灰口,6为集尘盒,7为观察窗口。
具体实施方式
下面结合附图,对本实用新型作进一步详细说明:参见图1,本实用新型的一种吸尘黑板擦,包括刷体1和刷毛2,其特征在于:所述刷体1的刷毛面上开设有吸尘孔3,刷体1内设有微型吸尘器4,微型吸尘器4和集尘盒6相连接,在集尘盒的下部设有卸灰口5,在集尘盒6的侧面设有观察窗口7。
擦黑板时打开微型吸尘器的电源,边擦黑板,边吸收粉尘,避免粉尘四处飞扬、污染教室空气,净化了教学环境,吸尘器吸收的粉尘都被集中到集尘盒里面,通过观察窗口,可以知道集尘盒装粉尘的情况,当集尘盒粉尘积满时,打开卸灰口,将粉尘倒出,便于使用。
