Description

一种吸尘黑板擦
技术领域
本实用新型涉及教学用具,具体是一种吸尘黑板擦。 
背景技术
目前,在学校中粉笔是教师经常使用工具,但是粉笔擦除时产生的粉笔灰一直是难以去除的粉尘污染。对学生和老师的身体健康构成了一定的威胁。现在也有许多发明和方法降低粉尘污染,如无尘粉笔、防尘黑板擦等,但是无尘粉笔造价高,也不能广泛应用在各个地区,而防尘黑板擦的设计一般仅在黑板擦的外部设一层防尘海绵等,这种使用效果不好,擦完后的粉笔末不能及时回收,仍然会被扬起而形成粉尘污染。 
发明内容
本实用新型为了克服上述现有技术存在的缺陷,提供一种结构简单、使用方便的吸尘黑板擦。 
本实用新型是通过以下技术方案来实现的:一种吸尘黑板擦,它包括黑板擦的本体,本体的正面设有刷毛,所述本体中空并安装有吸尘器,本体的背面安装有吸尘袋;所述吸尘器的吸尘口设置在吸尘袋和黑板擦的本体之间,吸尘器与吸尘袋相连通,吸尘袋为透气、隔尘的纱布,纱布上设有若干出气气孔;所述吸尘器与充电电池连接,本体外侧设置有控制开关。 
其有益效果可由对上述方案的叙述得知,由于在黑板擦上设计安装了吸尘器,使得擦除的粉笔末能及时被吸尘器吸入吸尘袋内,并且采用充电电池提供电源。吸尘袋采用透气隔尘的纱布,能有效将粉笔末隔离收集在吸尘袋内,方便使用完成后集中处理粉笔末。本实用新型大量可吸除使用黑板擦时产生的粉末,有利于学生和教师的身体健康,并且使用方便、制造成本低廉,具有明显的进步和实用性。 
附图说明:
图1为本实用新型剖视结构示意图。
图2为本实用新型的外部示意图。 
图中:1为刷毛,2为电池,3为吸尘器,4为本体,5为吸尘口,6为吸尘袋。 
具体实施方式:
为能清楚说明本方案的技术特点,下面根据附图对本实用新型具体实施方式作进一步说明。
具体实施方式:一种吸尘黑板擦,它包括黑板擦的本体4,本体4的正面设有刷毛1,本体4为中空,内部安装有吸尘器3。所述吸尘器3与充电电池2连接,本体4外侧设置有控制开关。本体4的背面安装有吸尘袋6;所述吸尘器3的吸尘口5设置在吸尘袋和黑板擦的本体之间,吸尘口5设置有多个。吸尘器3与吸尘袋6相连通,吸尘袋6为透气、隔尘的纱布,纱布上有若干细小的透气孔便于通气除尘。
