Abstract

本实用新型属教学用品。在本实用新型中,微型电动机减速后带动叶片、扇叶转动,叶片上的毛刷刷去黑板上的粉笔字迹,粉尘随扇叶产生的气流进入积尘盒,排去气流,粉尘便落入积尘盒底部。本实用新型具有使用方便,省力、无粉尘扬起的特点。

Description

本实用新型属于教学用品。
现有的黑板刷,存在着费力、使用时粉尘飞扬,影响人体健康等缺点,也有电动的黑板刷,但也存在使用不便的缺陷。本实用新型的目的就在于提供一种使用方便的、省力,无粉尘扬起的电动吸尘黑板刷。
本实用新型由叶片、扇叶、积尘盒、微型电动机等组成,其任务是通过如下方式完成的:
微型电动机减速后带动叶片、扇叶旋转,叶片上的毛刷随之旋转,刷去黑板上的粉笔字迹,同时,扇叶产生的向内的气流,使粉尘通过隔板上的锥形通孔进入积尘盒。气流和粉尘进入积尘盒后,气流通过排气孔中的滤纱排出,粉尘则落入底部。
下面将结合附图对本实用新型作进一步的描述:
附图1是电动吸尘黑板刷的剖视图。
附图2是电动吸尘黑板刷的正视图。
附图3、4是电动吸尘黑板刷的局部后视图。
如图1、2,叶片〔1〕上装有毛刷〔3〕,扇叶〔2〕后的空间里设置一隔板〔4〕,其上密布着细小的锥形通孔,锥形通孔的大口径面向扇叶〔2〕。装在外壳〔9〕下端的积尘盒〔8〕是可折卸的,积尘盒〔8〕上开有排气孔〔6〕,其中装有滤纱〔7〕。
隔板〔4〕的曲面呈球面,挡圈〔5〕是由弹性材料制成的。
如图3、4,外壳〔9〕上有用于固定电池盒〔11〕的插板〔13〕、外接电源插口〔14〕及电源开关〔10〕。
