Abstract

本实用新型涉及教学用品生产领域,提供了一种电动吸尘黑板擦。特点是擦吸头1上装有滚动的圆柱形毛擦条6,靠住毛擦条的侧边装有长条扁形的刮灰增阻条7。和现有产品相比,由于圆柱形毛擦条在使用中产生滚动,尘埃更易吸入集尘袋中,克服了原有产品栅栏式固定毛擦条易将粉尘挤压结块的缺陷。刮灰增阻条7除了对滚动毛擦条刮灰外,还能防止滚动毛擦条空转,从而增大毛擦条与黑板间的摩擦力,增大擦吸效果。本产品设计合理,方便实用,效果显著。

Description

电动吸尘黑板擦
本实用新型为一种擦抹黑板时能自动吸尘的电动吸尘黑板擦,属教学用品生产技术领域。
本实用新型是对申请号为97250272.6的“吸尘黑板擦”的进一步改进。原吸尘黑板擦的擦吸头上所安装的是固定式的呈栅栏状的毛擦条。由于毛擦条固定安装的原因,擦拭黑板时,粉尘会挤压在毛擦条上,有时还结块,吸尘效果还不够理想。
本实用新型的目的是要提供一种吸尘效果更为理想的电动吸尘黑板擦。
本实用新型的目的是这样加以实现的:电动吸尘黑板擦,包含有擦吸头1,壳体2、微型吸气风扇3、过滤集尘袋4、壳体内侧开设的导风槽5,特征在于擦吸头上装有滚动的圆住形毛擦条6,靠住毛擦条的侧边装有长条扁形的刮灰增阻条7。
下面结合附图对本实用新型作进一步说明。
图1为本实用新型的正面示意图。
图2为图1的右视剖面图。
图3为本实用新型的立体示意图。
过滤集尘袋4套于擦吸头1上以后,袋子其余部分与壳体之间具有空隙,减少了袋子贴住壳体而造成的吸尘阻力。擦拭过程中,手臂晃动,难免集尘袋碰住壳体,此时,导风槽5起到保证导风的作用。擦吸头1上安装的圆柱形毛擦条6在使用当中产生滚动,尘埃容易跌入集尘袋中。刮灰增阻条7除了对毛擦条6进行刮灰,还有一定增阻作用,也即是使得圆形毛擦条受到一定阻力,防止空转。
本实用新型构思严谨,设计合理,小巧玲珑,吸尘效果比现有吸尘黑板擦都为更好,在无电源供给情况下也能使用。本产品具有广阔的开发生产前景。
