Description

一种无尘黑板擦
技术领域
本实用新型涉及一种黑板擦,具体涉及一种无尘黑板擦,属于日常生活用品技术领域。 
背景技术
现在学校中使用的黑板擦很简单,包括板体和刷毛,这种结构简单的黑板擦在使用时非常容易将粉笔末弄得到处乱飞,并且粉笔末还容易在空气中漂浮,而被擦黑板者吸入肺中,对教师和同学们的健康造成很大危害。 
发明内容
本实用新型所要解决的技术问题是,针对现有技术的不足而提供一种无尘黑板擦的技术方案,该技术方案能够将擦黑板时产生的粉尘收集起来,达到无尘而利于健康的目的。 
本实用新型是这样实现的,一种无尘黑板擦,它有板体,板体底面设有刷毛,其特征在于,板体和刷毛装在壳体内,所述壳体为下端面敞口的空腔体,壳体内还装有吸尘器,吸尘器连通集尘仓,集尘仓侧面设有通气孔,通气孔上盖有过滤网。 
所述壳体上设有把手。 
所述壳体内中部装有电动机,电动机的传动轴连接到板体上,板体能随传动轴一起转动,电动机上连接有电源线。 
所述吸尘器为电动吸尘器,为现有技术,不再详述。 
本实用新型的有益效果:本实用新型结构简单、操作方便,吸尘器能有效吸附粉笔末,避免了粉笔末飞扬;电动机可以自动擦拭黑板,减少了人工擦黑板的劳动强度。 
附图说明
图1为本实用新型的结构示意图。 
其中,1—壳体,2—吸尘器,3—把手,4—集尘仓,5—电动机,6—传动轴,7—过滤网,8—通气孔,9—板体,10—刷毛,11—电源线。 
具体实施方式
下面结合附图对本实用新型的具体结构和原理做进一步说明。 
如图所示,本实用新型的一种无尘黑板擦,它有板体9,板体9底面设有刷毛10,其特征在于,板体9和刷毛10装在壳体1内,所述壳体1为下端面敞口的空腔体,壳体1内还装有吸尘器2,吸尘器2连通集尘仓4,集尘仓4侧面设有通气孔8,通气孔8上盖有过滤网7;所述壳体1上设有把手3;所述壳体1内中部装有电动机5,电动机5的传动轴6连接到板体9上,板体9能随传动轴6一起转动,电动机5上连接有电源线11。所述吸尘器2为电动吸尘器,自身带有电源或与电源形成电连接,为现有技术,不再详述。 
本实用新型是这样工作的,当需要擦黑板时,手握把手3,开启吸尘器2,把电源线11连接到电源上,打开电动机5使电动机转动起来,传动轴6将带动板体9进行转动,板体9底面的刷毛10就会把黑板上的粉笔字擦掉,同时,粉笔末被吸尘器2吸入集尘仓4内,吸入的风从通气孔8中排出,粉末被过滤网7过滤在集尘仓中。本实用新型可以自动擦拭黑板,又能有效吸附粉笔末,避免了粉笔末飞扬。
