Abstract

一种能够吸收粉笔尘的教学用电动吸尘板擦。它由毛毡、电机、壳体、壳体盖、手柄、吸尘管构成,由一个电机带动毛毡做旋转运动,壳体盖上开有吸尘口,吸尘口通过吸尘管与壳体上的吸尘管外接口连通,由电机驱动毛毡旋转,来擦净黑板的粉笔痕迹,在外接吸尘器产生的吸力作用下,粉笔尘通过吸尘管口被吸入吸尘器。可以在实现电动擦除黑板上粉笔痕迹的同时,吸收擦掉的粉笔尘。

Description

教学用电动吸尘板擦
所属技术领域
本实用新型涉及一种手持电动清洁黑板的教学用具,尤其是能吸收粉笔尘的教学用电动吸尘板擦。
背景技术
目前,教学用黑板上粉笔字迹的清洁,一般都采用手工黑板擦来回拖动来完成。用手工黑板擦擦完黑板,会有粉笔尘飞扬,污染教室环境,对教师和学生的身体健康造成危害,而且手工黑板擦来回拖动也增大了教师的劳动强度。
发明内容
为了克服手工黑板擦清洁黑板污染教室环境和消耗体力的不足,本实用新型提供一种教学用电动吸尘板擦,该板擦不仅可以吸收粉笔尘,防止粉尘飞扬,而且可以减轻教师擦黑板的劳动强度,提高教师教学时间利用效率。
本实用新型设备解决其技术问题所采用的技术方案是:由毛毡、电机、壳体、壳体盖、手柄、吸尘管构成,毛毡胶接在毛毡座上,毛毡座与电机轴固定连接,电机连接在壳体上,壳体的上部连接手柄,壳体下部连接壳体盖,壳体盖的边缘安装有吸尘管。工作中,采用电机驱动毛毡旋转,利用旋转的毛毡来擦去黑板上的粉笔迹,壳体盖上开有吸尘口,吸尘口通过吸尘管与壳体上的吸尘管外接口连通,粉尘会被从吸尘口吸入到外部的吸尘器里面,达到吸收粉笔尘,防止粉尘飞扬的目的。
本实用新型的有益效果是,可以在实现电动擦黑板上粉笔痕迹的同时,吸收粉笔尘,防止粉尘飞扬,减轻教师劳动强度,整机结构简单。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图1是教学用电动吸尘板擦的主视图。
图2是教学用电动吸尘板擦的仰视图。
图中1.电机,2.电机座,3.壳体,4.吸尘管外接口,5.吸尘管,6.毛毡座,7.毛毡,8.壳体盖,9.手柄
具体实施方式
在图中,可以旋转的毛毡(7)胶接在毛毡座(6)上,毛毡座(6)与电机(1)的输出轴固定联结,电机(1)通过电机座(2)连接在壳体(3)上;壳体(3)上部安装有手柄(9),壳体(3)下部连接着壳体盖(8),壳体盖(8)上开有八个吸尘口,吸尘口通过吸尘管(5)与吸尘管外接口(4)连通。
工作中,通过吸尘管外接口(4)外接一个吸尘器;手持手柄(9)移动到需要擦除的粉笔痕迹处,在电机(1)的驱动下,毛毡座(6)带动毛毡(7)旋转,擦净黑板的粉笔痕迹;在外接吸尘器产生的吸力作用下,粉笔尘通过吸尘管(5)被吸入吸尘器,完成黑板的粉笔痕迹擦除工作过程。
