具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解,现对照附图详细说明本发明的具体实施方式。
本发明为了解决现有技术中电子烟盒功能单一的缺点,提供了一种用于电子烟盒的控制电路,包括充电管理模块100、内置电池300、控制模块200、升压模块400,还包括电池电压检测模块600、负载检测模块900和指示模块800,还可以包括充电接口模块90、电池保护模块500、过流满电检测模块700,
下面就所有的模块的作用、电路构成及工作原理做详细阐述。
所述控制模块200分别与所述充电管理模块100、内置电池300、升压模块400、电池电压检测模块600、指示模块800、负载检测模块900、过流满电检测模块700相连接,所述内置电池300和升压模块400还同时连接至所述充电管理模块100,所述电池电压检测模块600还连接至所述内置电池300;充电接口模块90连接升压模块400和充电负载,电池保护模块500连接至内置电池300,过流满电检测模块700还连接至充电接口模块90;
所述充电管理模块100用于在外部电源80接入时提供充电电压,同时利用所述充电电压对所述内置电池300充电并发送电池充电信号至所述控制模块200;所述内置电池300用于在无所述外部电源80接入时直接提供所述充电电压;
电池电压检测模块600用于实时检测所述内置电池300的电池电压,并发送电池电压信号至所述控制模块200;负载检测模块900用于实时检测是否有充电负载接入,并发送负载检测信号至所述控制模块200,负载检测信号包括负载插入信号和负载拔出信号;
控制模块200用于根据所述电池电压信号、负载检测信号以及电池充电信号,控制升压模块400对所述充电电压进行调整向所述充电负载充电并控制指示模块800对充电状态进行实时显示。
上述充电状态包括用于指示所述内置电池300的电池电量的电池电量等级信号、用于指示所述内置电池300处于充电状态的电池充电中信号、用于指示所述内置电池300满充的电池满充信号、用于指示所述内置电池300电压过低的电池低压信号、用于指示所述内置电池300处于放电状态的电池放电信号;
具体的:
当有外部电源80接入时:
充电管理模块100将外部电源80进行调整输出为充电电压,同时利用充电电压对内置电池300进行充电,并发送电池充电信号至控制模块200;
所述控制模块200用于接收到所述电池电压信号,并根据所述电池电压信号计算所述电池电量进而控制所述指示模块800显示所述电池电量等级信号;所述控制模块200还根据所述电池电量是否达到满充条件控制所述指示模块800显示所述电池满充信号或电池充电中信号;
所述控制模块200还用于根据接收到的所述负载插入信号或负载拔出信号控制所述升压模块400的工作状态。因为控制模块200在接收的电池充电信号的条件下,可以判断有外接电源80接入,所以这种情况就不需要判断内置电池300是否处于低压,因为此时是通过外接电源80提供对充电负载的充电电压,不会出现内置电池300低压放电的情况。
当无外部电源80接入时:
当无外部电源80接入时,通过内置电池300直接提供充电电压,所述控制模块200不能接收到所述电池充电信号,因此,这种情况下需要考虑到可能会出现的内置电池300低压放电现象。
所述控制模块200用于接收到所述电池电压信号,并根据所述电池电压信号计算所述电池电量进而控制所述指示模块800显示所述电池电量等级信号;
所述控制模块200还用于在所述电池电压信号小于预设低压值,控制所述指示模块800显示所述电池低压信号以及控制所述升压模块400停止工作;
所述控制模块200还用于在所述电池电压信号大于等于预设低压值时,根据接收到的所述负载插入信号或负载拔出信号,控制所述升压模块400的工作状态以及控制所述指示模块800是否显示所述电池放电信号。具体的,在所述电池电压信号大于等于预设低压值且接收到负载插入信号时,控制所述升压模块400工作并控制所述指示模块800显示所述电池放电信号,在所述电池电压信号大于等于预设低压值且接收到负载拔出信号时,控制所述升压模块400不工作并控制所述指示模块800不再显示所述电池放电信号。
如此,本发明的指示模块800提供了各种工作状态或异常状态时的指示,且显示方式可以定制。负载检测模块900提供了充电插入检测功能以及充电拔出检测功能。且本发明的充电管理模块100既有充电管理功能,又提供了过压保护。
充电接口模块90包括电池杆接口91和Micro-USB接口92,在已有的电池杆接口91的基础上增加了Micro-USB接口92,使电子烟盒在对电池杆进行充电的基础上提供了更多的方便之处,例如可对手机电池等任何需要5V DC进行充电的Micro-USB接口的负载进行充电。
电池保护模块500用于提供对烟盒内置电池300的电路保护功能,特别是内置电池300的输出短路保护功能。
过流满电检测模块700用于检测连接在充电接口模块上的充电负载在充电过程中的负载充电电流,控制模块200根据负载充电电流控制升压模块400的工作状态,进而调节充电负载的电流,或在根据所述负载充电电流判断出充电负载满充时控制所述升压模块400停止工作。例如,如果充电负载的电流过大,则过流满电检测模块700将检测到负载充电电流过大,则控制模块200立即控制升压模块400降低对充电负载进行充电的电压,保证充电负载的电流不至于过大;如果充电负载已经满充了,则流入过流满电检测模块700的电流将会很小,过流满电检测模块700将检测到到负载充电电流很小,则控制模块200立即控制升压模块400停止工作,不再对充电负载充电。
