Abstract

本实用新型设计一种电动吸尘黑板擦,它由壳体、擦刷、叶轮、电动机组成。圆筒形擦刷仓头部装有条形擦刷,擦刷仓的后部连结有电机仓,一个带有叶轮的电机安装在仓内。电机仓的下部通过单向阀门连接有一个储灰箱。这样,在擦拭黑板时打开电机开关,叶轮高速旋转,粉笔灰通过擦刷仓吸入后被强大气流带入储灰箱,从而起到吸尘作用。

Description

电动吸尘黑板擦
本实用新型属于一种教学用具,涉及一种黑板擦的改进。
传统用于涂擦黑板的黑板擦一般采用机械式,没有吸尘装置,擦拭后粉笔灰直接洒落,随风飘散于教室,对教师、学生的身体健康造成很大危害。现有的各种吸尘黑板擦由于其结构不合理、造价高等因素,很难推广使用。
本实用新型的目的是设计一种电动吸尘黑板擦。它采用电机带动叶轮,将粉笔灰吸入腔内,从而达到除尘的目的。
本电动吸尘黑板擦的技术方案是:一种电动吸尘黑板擦,由壳体、擦刷、叶轮、电动机组成。壳体由擦刷仓、电池箱、电机仓及储灰箱组成。圆筒形擦刷仓头部装有条形擦刷,擦刷的后部安装有压缩弹簧,用力压按可以使擦刷缩进擦刷仓内;擦刷仓的后部连结有电机仓,一个带有叶轮的电机安装在仓内。电机仓的下部通过单向阀门连接有一个球形储灰箱,该球形储灰箱的上下两个半球之间装有合页,可以开关。这样,在擦拭黑板时打开电机开关,叶轮高速旋转,粉笔灰通过擦刷仓吸入后被强大气流带入储灰箱,从而起到吸尘作用。
本电动吸尘黑板擦具有结构简单,操作方便的优点,由于采用电机吸尘,其吸力大,可以很有效地将粉笔灰吸入,保证人体健康。
图1是本实用新型的结构示意图。
以下结合附图详细说明本电动吸尘黑板擦的实施例。如图1所示,壳体包括擦刷仓1、电池箱3、电机仓2及储灰箱4。圆筒形擦刷仓1头部装有后部装有弹簧的擦刷5,上下两个压缩弹簧通过弹簧盖6装入仓口的上下壁。这样用力压按擦刷5可以使其缩进擦刷仓内;电机仓2内装有一个带有叶轮7的电机8,电池安装在其上部的电池箱3内。电机仓2的下部通过单向阀门9连接有一个球形储灰箱4,该球形储灰箱的上下个半球之间装有合页,可以开关。球形储灰箱4上开有通气孔,在球体内铺有滤纸11,清除球内粉尘时只要将滤取出即可。
在电机与叶轮之间还设置有一个圆形过滤网片,这样可以阻止粉尘被抽至电机仓的后半部。
这样,在擦拭黑板时打开电机开关12,叶轮7高速旋转,粉笔灰通过擦刷仓与电机仓之间的吸入口10吸入后被强大气流带入储灰箱。
