Abstract

本实用新型公开了一种新型黑板擦,包括板体和海绵擦,所述板体内置有输液管,该输液管的上方和下方分别活动连接有出液管和弹性挤压管,在所述出液管上设有阀门,当黑板表面没有顽固的污渍时,关掉出液管上的阀门,只需干燥的海绵擦就可以除掉黑板表面的普通粉尘,当黑板表面有顽固的污渍时,先将黑板擦水平放置,打开出液管上的阀门,注入洗涤液至输液管和弹性挤压管,然后将整个黑板擦立起,保持设有出液管的一端向上,对黑板上的污渍进行擦拭。这时弹性挤压管受到压力发生形变,将洗涤液从出液管挤出,流在海绵擦上,海绵擦就能对黑板表面上较难清理的污渍进行有效清除了。

Description

一种新型黑板擦
技术领域
本实用新型涉及一种学习用品领域,尤其是一种新型黑板擦。
背景技术
现有的黑板擦在擦拭黑板时,只能擦掉黑板表面粉尘,对于一些较为难清理的污渍需要用湿擦布来擦拭,操作起来不方便,且清理效果一般。
实用新型内容
本实用新型技术任务是针对上述技术不足,提供一种新型黑板擦。
本实用新型解决技术问题所采用的技术方案是:一种新型黑板擦,包括板体和海绵擦,所述板体内置有输液管,该输液管的上方和下方分别活动连接有出液管和弹性挤压管,在所述出液管上设有阀门。
本实用新型所能带来的有益效果是:有效解决了现有黑板擦较难清理黑板表面顽固污渍的问题。
附图说明
图1、本实用新型结构示意图。
具体实施方式
下面结合附图,对本实用新型做以下详细说明:
如图1所示,本实用新型公开了一种新型黑板擦,包括板体1和海绵擦2,所述板体1内置有输液管6,该输液管6的上方和下方分别活动连接有出液管4和弹性挤压管3,在所述出液管4上设有阀门5。
当黑板表面没有顽固的污渍时,关掉出液管4上的阀门5,只需干燥的海绵擦2就可以除掉黑板表面的普通粉尘。
当黑板表面有顽固的污渍时,先将黑板擦水平放置,打开出液管4上的阀门5,注入洗涤液7至输液管6和弹性挤压管3,然后将整个黑板擦立起,保持设有出液管4的一端向上,对黑板上的污渍进行擦拭。这时弹性挤压管3受到压力发生形变,将洗涤液7从出液管4挤出,流在海绵擦2上,海绵擦2就能对黑板表面上较难清理的污渍进行有效清除了。
本实用新型结构简单,使用方便,有效解决了现有黑板擦较难清理黑板表面顽固污渍的问题。
