Abstract

一种能够不需要大功率照明系统,就可使用的写字笔。它是在笔杆中,电池组、发光二极管,开关构成一闭合回路。在黑暗的环境中,合上开关,只需耗费很小的电能,即可书写、阅读,当在明亮处,打开开关,可作为一般性的笔使用。

Description

节能写字笔
所属技术领域
本实用新型涉及一种能够节约电能的书写工具,并且能方便人们在黑暗的环境中,无照明系统的情况下进行书写的写字笔。
背景技术
目前,公知的书写工具,如钢笔、圆珠笔等,必须要有功率很大的照明设备,才能在黑暗的环境中使用。这不仅消耗大量的电能,而且给人们的书写带来了不便。
发明内容
为了克服现有的书写工具在黑暗的环境中必需功率很大的照明设备的不足,本实用新型提供一种写字笔,该写字笔不仅能节约电能,而且能方便人们在黑暗的环境中使用。
本实用新型解决其技术问题所采用的技术方案是:在金属外壳中,金属后盖、电池组、弹簧和圆形金属片顺序电连接,在透明塑料外壳下端设置两个发光二极管,使两个发光二极管的阳极与金属外壳电连接,阴极同时与一金属环电连接,金属环通过开关与圆形金属片电连接。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图1是本实用新型的电路原理图。
图2是节能写字笔沿轴线方向的剖面图。
图3是透明塑料外壳的局部俯视图。
图4是图3的A-A剖视图。
图中:1金属后盖  2金属外壳  3、4、5纽扣电池  6弹簧  7圆形金属片  8、9导线  10透明塑料外壳  11金属环  12、13发光二极管  14透明塑料笔头  15、16发光二极管阳极  17、18发光二极管阴极  19、21导线  20开关
具体实施方式
在图2中,金属后盖(1)与由纽扣电池(3)、(4)、(5)组成的电池组的正极相接触,金属外壳(2)与透明塑料外壳(10)相套合,使得透明塑料外壳壁内的导线(8)、(9)的一端与金属外壳(2)电连接,另一端分别与发光二极管的(12)、(13)的阳极(15)、(16)电连接,发光二极管(12)、(13)的阴极(17)、(18)与金属环(11)电连接,导线(21)的一端与金属环(11)电连接,另一端与开关(20)电连接,其中,开关(20)可沿导线(21)上下滑动,从而控制电路的通断,导线(19)的一端与开关(20)电连接,另一端与圆形金属片(7)相接触,而圆形金属片(7)通过弹簧(6)与电池组的负极电连接,笔芯置于透明塑料外壳中。

Claims (2)

1.一种节能写字笔,在笔杆上部设置一金属外壳,在笔杆下部内置两个发光二极管,发光二极管的阳极与金属外壳电连接,阴极与圆形金属片电连接,其特征是:在笔杆内,电池组、发光二极管、开关构成一闭合回路。
2.根据权利要求1所述的节能写字笔,其特征是:两个发光二极管相并联,阳极与金属外壳电连接,阴极与圆形金属片电连接,开关附于透明塑料外壳外表面。
