背景技术  众所周知,现在学校中教师讲课时大多使用黑板擦擦拭黑板,或者值日的学生在清理黑板时,现有的黑板擦易落灰尘,由于板擦擦拭面积较小,所示在清理黑板时非常费时费力,虽然现在出现了许多有关清理黑板的用具,但是大多结构复杂,操作繁琐,而且制作成本较高。
发明内容  本实用新型的目的在于提供一种结构新颖、省时省力、方便实用、操作简便、造价低廉、易于推广的黑板刷。
本实用新型包括水箱、水管以及擦板,所述水箱为长方形箱体,在其一侧边设有注水口,并注水口处活动连接挡塞;在水箱的底面连接与其相通的水管,所述水管由软塑料制成的,上述水管最好为两个,其另一端管口与擦板顶面连接,所述擦板为中空长方体结构,为外形美观,擦板最好与水箱形状相同,在上述水箱及擦板之间连接弹簧,弹簧最好为两个,并分别连接在水管的两侧,在上述擦板的一侧面开设若干个水孔,并水孔周边设有刷毛;在与擦板表面与水孔相对侧面设有把手。
本实用新型在使用时,将水箱安装在黑板的顶边上,可先将黑板简单擦拭,然后向水箱内注水,水由水管进入擦板,再由各个水孔分流流向黑板面,使用者手扶把手上下拉拽擦板,擦拭黑板。
本实用新型与现有技术相比具有如下优点:结构新颖、省时省力、方便实 用、操作简便、造价低廉、易于推广。
附图说明  图1为本实用新型的立体示意简图。
图2为本实用新型的擦板的主视示意简图。
具体实施方式  如图1、图2所示,水箱1为长方形箱体,在其一侧边设有注水口2,并注水口处活动连接挡塞3;在水箱的底面连接两个与其相通的水管4,所述水管由软塑料制成的,其另一端管口与擦板5顶面连接,所述擦板为中空长方体结构,在水箱及擦板之间连接弹簧6,两个弹簧分别连接在水管的两侧,在上述擦板的一侧面开设若干个水孔7,并水孔周边设有刷毛8;在与擦板表面与水孔相对侧面设有把手9。
