Abstract

一种具有吸尘器的黑板是涉及黑板结构的改进。本实用新型就是提供一种使用方便、有效的避免黑板粉尘污染的具有吸尘器的黑板。本实用新型包括黑板,其结构要点黑板底部的框架上设置有吸尘口,吸尘口通过软管同吸尘器相连。

Description

一种具有吸尘器的黑板
技术领域:
本实用新型是涉及黑板结构的改进。
背景技术:
黑板作为教学当中的第一教具,一直在各类教学活动中扮演着重要角色。但长久以来,虽然有各种新材料、新结构的推出,使黑板不断发展;可是粉尘对教师及学生的侵害一直没有得到根本解决。采用白板用水性笔书写,成本太高;采用钢板作书写板面,可以适当降低粉尘,但粉尘依然存在;采用吸尘黑板擦,效果不理想。
实用新型内容:
本实用新型就是针对上述问题,提供一种使用方便、有效的避免黑板粉尘污染的具有吸尘器的黑板。
本实用新型采用如下技术方案:本实用新型包括黑板,其结构要点黑板底部的框架上设置有吸尘口,吸尘口通过软管同吸尘器相连。
本实用新型的有益效果:
由于本实用新型黑板底部的框架上设置有吸尘口,吸尘口通过软管同吸尘器相连;黑板擦用后可放置在吸尘口上,启动吸尘器,就可将黑板擦上的粉尘吸入吸尘器内;避免了粉笔灰在空中漂散、污染了空气。只要打开电开关,就可很方便完成这一工作,使用起来很是方便。
附图说明:
图1是本实用新型的结构示意图;
图2是图1的A部局部放大图。
具体实施方式:
本实用新型包括黑板1,黑板1底部的框架2上设置有吸尘口4,吸尘口4通过软管6同吸尘器7相连。
吸尘器7的电开关5可置于吸尘口4的下方,以便手动的控制。
使用时,将沾有粉笔粉尘的黑板擦3置于框架2的吸尘口4上,按动电开关5,吸尘器7启动,就可将黑板擦3上的粉尘吸走。
