Description

吸尘式板擦
本实用新型涉及一种吸尘式板擦，属于教学用具的技术领域。
学校里教师不断地用粉笔书写，在用黑板刷子擦净时，粉尘飞扬，很不利于教师的健康。如果用湿布擦净，效果虽佳，但黑板不能立即干，不免影响教学效率，近年来也有人对粉笔做出过改进，使粉尘略有减少，但并不能解决根本问题。因此，亟需有一种黑板刷，使用时可以吸去粉尘。
本实用新型的目的是要提供一种吸尘式板擦，它可以克服上述的缺点。本板擦装有电动机和风机，在擦拭黑板时，粉尘可以吸附于粉尘盒，使粉尘不致飞扬，同时也便于清除。
本实用新型的目的是这样实现的：机壳(12)右部内装有电动机(1)，中部装有风机(2)且与电动机(1)相连接，机壳(12)左部有粉尘室(3)和传动机构(5)和刷子(6)，另有电池盒(4)内装干电池(7)，由弹簧(8)和导电片(9)支撑，由导线连接于电动机(1)。传动机构(5)的底座(15)中部有一传动轴(24)，轴的两端用小轴(29)支承于支座(25)，支座(25)的左下端与支承板(27)用轴(28)支承，支座(25)另一端以钢丝(30)连接一叶板(19)，传动轴(24)中部又以钢丝(31)连接于连接板(32)，该板固定于摆动板(17)。刷子(6)中部是长条形，两侧粘有由2个W形状的棉刷组成的刷子。吸盒室(4)内装有抽屉式粉尘盒(14)，该盒端面有一方孔(21)，另一端面有圆孔(22)，端面粘固一滤布(23)。

图2.图1的A向视图
图3.粉尘盒示意图
图4.传动机构示意图(俯视图)
图5.传动机构示意图(正视图)
兹结合附图对吸尘式板擦的结构详细叙述：
由图1，机壳(12)右部是一圆柱体，内装一个电动机(1)，机壳中部装有一风机(2)，电动机轴(1)与风机(2)连接，机壳中部的表面均匀分布4个矩形通风孔(10)；机壳(12)左部有一粉尘室(3)，其壳体右侧有通风孔(13)，使风可进入粉尘室(3)，粉尘室(3)内装有一个抽屉式的粉尘盒(14)，盒的一端有一提手(11)用于拉出粉尘盒(14)；机壳(12)左部还有一传动机构(5)和刷子(6)，机壳(12)左部有电池盒(4)内装干电池(7)，由弹簧(8)和导电片(9)支撑。
由图2，传动机构(5)的底座(15)的中部有2条长矩形孔(16)，底座(15)的背面粘帖刷子(6)，该刷子的中部是长条形，两侧粘有由2个W形状的棉刷组成的刷子；W形刷子只有一部分遮盖着长矩形孔(16)，所以擦黑板时粉笔的粉尘可由此孔(16)进入粉尘盒(14)；底座(15)的背面用小轴(18)固定叶板(19)于底座上面，底座(15)的上下两端均有一长孔(20)，叶板(19)活动时也可由此长孔(20)吸入粉尘。
由图3，粉尘盒(14)是一抽屉式盒体，一端有一提手(11)，端面一侧有一近似于矩形的孔(21)，相对的另一侧面有一圆孔(22)；  滤网式滤布(23)可以粘帖于盒面上，也可用螺丝或其他方式固定，滤布(23)有过滤作用，粉尘进入粉尘盒(14)后，逐渐多了时候便形成堆积，稍满时可拉动提手(11)，拉出粉尘盒(14)，从矩形的孔(21)中倒出粉尘后再放回粉尘室(3)内继续使用。
由图4、5，底座(15)的中部有一传动轴(24)，轴的两端用小轴(29)支承于支座(25)上，支座(25)的截面是T字形，其左下端与支承板(27)用轴(28)支承，支座(25)右下端以钢丝(30)连接一叶板(19)，传动轴(24)中部又以钢丝(31)连接于连接板(32)，该板下端固定于摆动板(17)上面，一侧有挡块(33)。
擦黑板时，传动轴(24)左右摆动，通过支座(25)以轴(28)为支点，支座也摆动，钢丝(30)牵动叶板(19)以轴(18)为支点也摆动，底座(15)的底面内装有刷子(6)。
与现有技术相比，吸尘式板擦具有以下优点：1.擦黑板时风机通风，可把粉尘吸入粉尘盒内，使粉尘不致飞扬。2.不仅可用于擦黑板，也可用于建筑行业擦除墙壁的灰土。3.如采用塑料件制作，造型新颖美观，重量较轻，使用灵便。
