Abstract

本实用新型提供一种无尘黑板擦,包括黑板擦、壳体、摩擦辊、橡胶片,其特征在于:所述摩擦辊固定在黑板擦四周;所述橡胶片设置在壳体内壁上;所述黑板擦嵌入壳体中,与壳体顶部形成封闭的集粉尘室;所述摩擦辊与橡胶片充分接触;所述壳体一侧设有活动推门。本实用新型无尘黑板擦结构非常简单,能吸附擦黑板时产生的粉尘,有效的保护好环境。

Description

无尘黑板擦
技术领域
本实用新型涉及一种黑板擦,尤其涉及一种无尘黑板擦。
背景技术
目前国内虽有少量学校采用电化教学,但多数学校仍然使用粉笔执教。特别在农村,大量中、小学校内所有的黑板擦都不能吸尘,致使粉尘到处飞扬,对教师和学生的健康极为不利。
实用新型内容
本实用新型的目的是提供一种无尘黑板擦,该无尘黑板擦结构非常简单,能吸附擦黑板时产生的粉尘,有效的保护好环境。
为实现上述目的,本实用新型的技术方案是:一种无尘黑板擦,包括黑板擦、壳体、摩擦辊、橡胶片,其中,所述摩擦辊固定在黑板擦四周;所述橡胶片设置在壳体内壁上;所述黑板擦嵌入壳体中,与壳体顶部形成封闭的集粉尘室;所述摩擦辊与橡胶片充分接触;所述壳体一侧设有活动推门。
本实用新型由于采用上述技术方案,使之与现有技术相比,具有的积极效果是:本实用新型无尘黑板擦结构非常简单,能吸附擦黑板时产生的粉尘,有效的保护好环境。
附图说明
图1是本实用新型无尘黑板擦的结构示意图。
具体实施方式
如图1所示,一种无尘黑板擦,包括黑板擦1、壳体2、摩擦辊3、橡胶片4,其中,所述摩擦辊3固定在黑板擦1四周;所述橡胶片4设置在壳体2内壁上;所述黑板擦1嵌入壳体2中,与壳体2顶部形成封闭的集粉尘室6;所述摩擦辊3与橡胶片4充分接触;所述壳体2一侧设有活动推门5。
擦黑板时,摩擦辊3也会和黑板接触,将粉尘粘起,同时在其旋转的过程中与壳体2内壁上的橡胶片4摩擦,一方面将摩擦辊3粘的粉尘刮下,另一方面两者摩擦产生静电也更利于吸尘。刮下的粉尘落入封闭的集粉尘室6,集粉尘室6里的粉尘集到一定数量,打开壳体2一侧的活动推门5,将集粉尘室6里的粉尘倒出即可。
