Abstract

一种延时开关包括延时开关按钮、延时控制模块,其特征在于,交流电源、延时开关按钮、延时控制模块、灯泡依次连接。延时开关按钮打开时,延时控制模块不起作用,延时开关按钮关闭时,交流电源对延时控制模块短时间充电,通过延时控制模块对灯泡提供一分钟左右的短暂电力。

Description

延时开关
技术领域
 本实用新型涉及一种用电控制设备,尤其是一种开关。
背景技术
在夜间,用户关闭传统的电源开关后,灯泡立即熄灭,造成短时间内用户在黑暗中行动的不便。
发明内容
为了克服上述的问题,本实用新型提供一种延时开关,该延时开关在延时开关按钮关闭后,仍然为灯泡提供少量电源,灯泡点亮一分钟左右后关闭,为用户在关闭电源后的短时间内的行动提供方便。
本实用新型解决其技术问题所采用的技术方案是:延时开关包括延时开关按钮、延时控制模块,其特征在于,交流电源、延时开关按钮、延时控制模块、灯泡依次连接。延时开关按钮打开时,延时控制模块不起作用,延时开关按钮关闭时,交流电源对延时控制模块短时间充电,通过延时控制模块对灯泡提供一分钟左右的短暂电力。
本实用新型的有益效果是,结构简单、为用户提供便利,具有广泛的使用价值。
附图说明
图1是本实用新型的原理框图;  图2是本实用新型的电结构图。
具体实施方式
在图1中,延时开关包括延时开关按钮1、延时控制模块2,其特征在于,交流电源3、延时开关按钮1、延时控制模块2、灯泡4依次连接。延时开关按钮1打开时,延时控制模块2不起作用,延时开关按钮1关闭时,交流电源3对延时控制模块2短时间充电,通过延时控制模块2对灯泡提供一分钟左右的短暂电力。
在图2中,当正常照明时,将开关K 合上,此时220V 交流电直接加在灯泡上,同时市电经按钮开关、电阻R1、D 向电容C 快速充电,当关闭开关K后,由于电容经R2 放电使可控硅导通,继续点亮灯泡,延时大约1 分钟左右。
