【技术实现步骤摘要】
本技术属于教具
,特别是涉及一种吸尘板擦。
技术介绍
当前大家所熟知的黑板擦品种齐全,样式繁多,从檫试物看有毛刷型和毡型,从结构上看有手动和电动的区分。但是他们都容易产生粉尘,而不产生粉尘的造价又太高。如果粉尘吸附在板擦上,不仅影响板擦的质量,更主要的是如果被人吸入,会对人的身体造成伤害。
技术实现思路
为克服普通板擦不能吸尘或能吸尘但造价又太高问题,本技术提供一种吸尘板擦。本技术为解决公知技术中存在的技术问题所采取的技术方案是:一种吸尘板擦,包括刷体、刷头和后盖,所述刷头和后盖之间形成的箱体内设有直流电机和蓄电池,所述直流电机通过链条带动从动链轮,所述从动链轮安装于从动轴的一端,所述从动轴安装于刷体,所述从动轴上还安装有主动滚筒,所述主动滚筒上设置有履带,所述履带连接从动滚动,所述从动滚动连接从动滚轴上,所述履带与硬质刷接触,所述硬质刷安装于收集箱的内壁上;所述主动滚动的两端分别安装有一个主皮带轮,所述主皮带轮通过皮带带动副皮带轮,两个副皮带轮设于竖轴上,所述竖轴设于刷体上,所述竖轴下端设有圆刷。本技术还可以采用如下技术措施:所述直流电机的后面设有收集箱,收集箱与刷体活动连接。本技术具有的优点和积极效果是:1.采用刷毛及圆刷檫试黑板,圆刷能够吸附粉尘,履带能够吸附灰尘,减少了粉尘在空气中的漂浮,避免了对人体的伤害。2.在圆刷和硬质刷的作用下,可以将一部分粉尘扫入收集箱内,使粉尘不会漂浮在空中。附图说明图1是本技术结构主视图;图2是图1俯视图 ...
【技术保护点】
