Abstract
本实用新型公开了一种吸尘黑板擦，包括壳体；壳体上安装有吸尘器，在壳体上位于吸尘器的外围设有擦尘布，擦尘布的底面低于吸尘器的底面。本实用新型的结构，由于设置了吸尘器，且擦尘布位于吸尘器的外围，当在擦黑板时，粉笔灰会被吸尘器吸附并收集，防止了粉笔灰到处飞扬，减小了粉笔灰对师生的呼吸系统、眼睛、皮肤的危害，也减小了粉笔灰对空气质量的影响。
Description
—种吸尘黑板擦
技术领域
[0001] 本实用新型涉及黑板擦。
背景技术
[0002] 平时用的黑板擦一般用一整块软绵作为擦体，能吧黑板上的粉笔痕迹擦干净，但在擦黑板过程中，粉笔灰灰到处飞扬。而粉笔是由石膏制成的，其化学成分为硫酸钙，这种物质对师生的呼吸系统、眼睛、皮肤具有一定的危害性，并且粉笔灰会影响空气的质量。
发明内容
[0003] 为解决上述技术问题，本实用新型提供了一种吸尘黑板擦。
[0004] 解决上述技术问题的技术方案是：一种吸尘黑板擦包括壳体；壳体上安装有吸尘器，在壳体上位于吸尘器的外围设有擦尘布，擦尘布的底面低于吸尘器的底面。
[0005] 本实用新型的有益效果是：由于设置了吸尘器，且擦尘布位于吸尘器的外围，当在擦黑板时，粉笔灰会被吸尘器吸附并收集，防止了粉笔灰到处飞扬，减小了粉笔灰对师生的呼吸系统、眼睛、皮肤的危害，也减小了粉笔灰对空气质量的影响。
附图说明
[0006] 图I为吸尘黑板擦的主视图。
[0007] 图2为A-A的剖视图。
[0008] 图3为吸尘黑板擦的仰视图。
具体实施方式
[0009] 下面结合附图和具体实施方式对本实用新型进行进一步详细说明。
[0010] 如图I至图3所示，一种吸尘黑板擦包括壳体I ;壳体I上安装有吸尘器2，在壳体上位于吸尘器的外围设有擦尘布3，擦尘布3的底面低于吸尘器2的底面。
[0011] 如图2所示，所述的吸尘器2包括座体31、马达32、吸尘风扇33、充电电池34、开关35，所述的座体31安装在壳体I上，所述的座体31上设有尘埃收集空间36，用于收集、储存粉笔灰，马达32固定在座体31上，吸尘风扇33安装在马达32的输出轴上，充电电池34安装座体31内，开关35安装座体31上，充电电池通过开关与马达电连接；所述的座体上设有与充电电池电连接的充电口。
[0012] 使用时，通过开关35启动马达32，马达的输出轴带动吸尘风扇33旋转，然后，利用吸尘黑板擦擦黑板，在擦黑板过程中，粉笔灰在吸附风扇的作用下被收集到尘埃收集空间内，这样，粉笔灰就不会到处飞扬了，减小了粉笔灰对师生的呼吸系统、眼睛、皮肤的危害，也减小了粉笔灰对空气质量的影响。
