Description
技术领域：
本实用新型涉及一种模仿蜡烛燃烧和熄灭的电子蜡烛灯。
背景技术：
现有的电子蜡烛灯，品种繁多，为人们的生活增添了不少情趣。但有些电子蜡烛灯，尚存在仿真效果不够理想，形态不够逼真的缺陷。
实用新型内容：
本实用新型的目的就是提供一种电子蜡烛灯，仿真效果好，形态逼真，能模仿蜡烛忽明忽暗的摇曳火焰，又可以用嘴吹灭或者吹亮。
为实现上述目的，本实用新型电子蜡烛灯，包括发光体、控制电路和中空的蜡烛体，控制电路设于蜡烛体空腔内，发光体设置在蜡烛体上，发光体连接控制电路，所述中空蜡烛体的顶部端面呈内凹的抛物面状，发光体为火焰外形发光二极管，设置在蜡烛体顶部的内凹端面，该内凹端面还设有吹气孔，蜡烛体内靠吹气孔侧设置连接控制电路的风控器，控制电路包括驱动电路和蜡烛控制器，风控器产生的信号经驱动电路放大至蜡烛IC的输入端，火焰外形发光二极管连接蜡烛控制器输出端。当蜡烛控制器输入端具有触发信号时，其输出端进行脉冲低电平与恒定高电平之间的电压转换，控制火焰外形发光二极管闪亮或熄灭。
在优选实施方式中，上述中空的蜡烛体为圆筒形，火焰外形发光二极管设置在圆筒形蜡烛体顶部内凹端面的中央。风控器为压电陶瓷片。蜡烛控制器为蜡烛IC。火焰外形发光二极管为黄色发光二极管。蜡烛体空腔内设置置电池的供电装置，蜡烛体外侧壁设置接通或断开电池的开关。
本实用新型由于采用了风控器，当用嘴对着吹气孔吹气时，可以通过控制电路控制火焰外形发光二极管闪亮或熄灭，火焰外形发光二极管闪亮时，颜色为黄色，酷似蜡烛忽明忽暗的摇曳火焰，既方便卫生又富有情趣。
附图说明：
图1是本实用新型实施例的外观示意图；
图2是本实用新型实施例的结构示意图；
图3是本实用新型实施例的电路原理图；
具体实施方式：
以下结合附图详述本实用新型实施例的结构细节：
如图1至图3所示，本实用新型实施例包括火焰外形发光二极管LED、控制电路和圆筒形蜡烛体1。火焰外形发光二极管LED选用黄色发光二极管。蜡烛体1空腔内设置控制电路，设置置两节电池BT的供电装置，蜡烛体1外侧壁的底部设置接通或断开电池BT的开关SW。蜡烛体1的顶部端面11呈内凹的抛物面状，火焰外形发光二极管LED连接控制电路，设置在蜡烛体1顶部内凹端面11的中央，该内凹端面11还设有吹气孔12，蜡烛体1内靠吹气孔12侧设置连接控制电路的风控器Y，风控器Y选用压电陶瓷片。
如图3所示，控制电路包括驱动电路和蜡烛控制器，驱动电路包括三极管Q1、Q2和电阻R1、R2，蜡烛控制器选用蜡烛IC，蜡烛IC是专用集成芯片。当将开关SW接通，两节电池BT就向电路供电，火焰外形发光二极管LED在蜡烛IC的控制下不停的闪动，闪动时的颜色为黄色，酷似蜡烛燃烧时忽明忽暗的摇曳火焰。当用嘴对着吹气孔12吹气时，发光二极管LED就会熄灭，再吹气，发光二极管LED又闪亮，再吹气，发光二极管LED熄灭……。这是因为：当用嘴对着吹气孔12吹气时，压电陶瓷片Y受到振动或气流，产生脉冲信号，此脉冲信号经驱动电路的三极管Q1、Q2整形放大后，输入至蜡烛IC的输入端IN，蜡烛IC的输出端OUT进行一次电压转换，即原来是脉冲低电平，转换为恒定高电平；原来是恒定高电平，转换为脉冲低电平。当蜡烛IC的输出端OUT为脉冲低电平时，连接蜡烛IC输出端OUT的火焰外形发光二极管LED闪亮；当蜡烛IC的输出端OUT为恒定高电平时，连接蜡烛IC输出端OUT的火焰外形发光二极管LED熄灭。当不断地吹气时，压电陶瓷片Y不断地受到气流的变化，它就不断地产生脉冲信号，蜡烛IC的输出端OUT不断地进行电压转换，火焰外形发光二极管LED就会由闪亮到熄灭，或者由熄灭到闪亮。
本实用新型仿真效果好，形态逼真，在营造气氛时，能增添不少的乐趣。
