Abstract

本实用新型集尘黑板擦，主要包括集尘盒、擦板和擦棉，其特征是：所述集尘盒是个四壁向内倾斜的无盖盒子，盒底中间连接有一块擦板和擦棉。擦棉具有极强的弹性，其厚度略高出于集尘盒，当用力按住黑板擦擦黑板时，擦棉会被压缩到集尘盒一样厚，集尘盒四壁紧贴黑板，使集尘盒内成为密封状态，擦棉擦下的粉笔灰只能落在集尘盒内，而不会飘散出去。本实用新型集尘黑板擦，结构简单，制作简易，成本低廉，易于推广。

Description

集尘黑板擦
技术领域：
本实用新型涉及一种教学用具，尤其是一种集尘黑板擦。
背景技术：
现有黑板擦用于擦拭黑板上的粉笔字时，粉笔灰都会漫天飞扬，弄得人身上和课桌上到处都是，极不卫生。
发明内容：
本实用新型的目的在于提供一种集尘黑板擦，黑板擦本身带有一个集尘盒，可以收集粉笔灰，不会使之到处飞扬。
本实用新型通过以下技术方案实现：本实用新型集尘黑板擦，主要包括集尘盒、擦板和擦棉，其特征是：所述集尘盒是个四壁向内倾斜的无盖盒子，盒底中间连接有一块擦板和擦棉。擦棉具有极强的弹性，其厚度略高出于集尘盒，当用力按住黑板擦擦黑板时，擦棉会被压缩到集尘盒一样厚，集尘盒四壁紧贴黑板，使集尘盒内成为密封状态，擦棉擦下的粉笔灰只能落在集尘盒内，而不会飘散出去。
本实用新型集尘黑板擦，结构简单，制作简易，成本低廉，易于推广。
附图说明：
图1是本实用新型的构造示意图。
其中1-集尘盒，2-擦棉，3-擦板。
具体实施方式：
如图1所示，本实用新型集尘黑板擦，主要包括集尘盒(1)、擦板(3)和擦棉(2)，其特征是：所述集尘盒(1)是个四壁向内倾斜的无盖盒子，盒底中间连接有一块擦板(3)和擦棉(2)，擦板(3)和擦棉(2)都小于集尘盒(1)，使集尘盒(1)内留有一定空间以便收集粉笔灰。
擦棉(2)具有极强的弹性，其厚度略高出于集尘盒(1)，当用力按住集尘黑板擦擦黑板时，擦棉(2)会被压缩到集尘盒(1)一样厚，集尘盒(1)四壁紧贴黑板，使集尘盒(1)内成为密封状态，擦棉(2)擦下的粉笔灰只能落在集尘盒(1)内，而不会飘散出去，又因集尘盒(1)的四壁向内倾斜，所以集尘盒(1)内收集的粉笔灰不会轻易倒出去。清理粉笔灰时，只要把集尘黑板擦向下抖一抖就可以了。
