Abstract

本实用新型属教学用具,具体涉及一种吸尘黑板。其特征是板面上均布设有若干个微孔,板面背面设置与板面相对应的封闭隔板,封闭隔板与板面之间形成空腔内设吸气风扇,底框为空心腔体,空腔与底框空心腔体相贯通。具有擦除板书字迹时产生的粉尘不四处弥散,无环境污染,便于清洁处理的优点。

Description

吸尘黑板
技术领域:
本实用新型属教学用具,具体涉及一种吸尘黑板。
背景技术:
现有的黑板是由板面和底框构成,用粉笔书写擦除字迹时,产生的粉尘四处弥散,易被老师和学生吸进,影响身体健康,造成空气污染。
发明内容:
本实用新型的目的是提供一种结构简单、使用方便、无粉尘污染的吸尘黑板。
本实用新型的技术方案是:一种吸尘黑板,在板面下端设有底框,其特征是板面上均布设有若干个微孔,板面背面设置与板面相对应的封闭隔板,封闭隔板与板面之间形成空腔内设吸气风扇,底框为空心腔体,空腔与底框空心腔体相贯通。
由于采用上述技术方案,用粉笔书写擦拭时,产生的粉尘,在吸气风扇的作用下经微孔吸入封闭隔板与板面之间形成的空腔内,并在重力的作用下落入底框空心腔体中,具有擦除板书字迹时产生的粉尘不四处弥散,无环境污染,便于清洁处理的优点。
附图说明:
以下结合附图和具体实施例来对本实用新型的技术方案做详细说明。附图是本实用新型的结构示意图。
具体实施方式:
参考附图,一种吸尘黑板,在板面1下端设有底框2,板面1上均布设有若干个微孔3,板面背面设置与板面相对应的封闭隔板4,封闭隔板4与板面1之间形成空腔5内设吸气风扇6,底框2为空心腔体,空腔5与底框2空心腔体相贯通。
