Description

电子烟电池杆电路和电子烟电池杆 技术领域
本实用新型涉及电子烟技术领域，特别涉及一种电子烟电池杆电路和电子烟电池杆。
背景技术
电子烟是一种新型的电子产品，其与普通的香烟有着相同的外观，以及与香烟相同的味道，但是电子烟相对于传统的香烟更为的健康以及环保。电子烟是通过雾化芯将含有烟碱和香精的烟液雾化成颗粒输出。电子烟中不含普通香烟中的焦油和其他有害成分，也不会产生二手烟。
现有技术中的电子烟一般包括电池杆组件和雾化组件两部分，其中雾化组件内包括用于存储烟油的储油空间和用于雾化该储油空间内的烟油的电热丝，电池杆组件包括电子烟电池。当电池杆组件和雾化组件组合在一起时，电子烟电池用于给电热丝供电，当电池杆组件插入充电器时，电子烟电池从充电器中获取电能以充电。
然而，现有的充电器在给电池杆充电时，用户无法判断充电器向电池杆输入的电压是否正常，而且也不能直观看出电池杆具体充电的进度，而在使用电子烟时，用户也无法查看电子烟电池的剩余电量，这降低了电子烟的用户体验。

下面对本实用新型中的电子烟电池杆电路的具体结构进行进一步的详细说明。需明确的是，以下为对本实用新型中的电子烟电池杆电路中的各模块的举例说明，并不作限定。
请参阅图3，图3是本实用新型的电子烟电池杆电路中充放电模块的一个实施例的结构示意图。如图3所示，本实施例所示的充放电模块具体包括：第一三极管Q1、第一场效应管Q2、第二场效应管Q3、第一电阻R1、第二电阻R2、第三电阻R3和第四电阻R4；
所述第一电阻R1的一端和所述微处理器U1相连，另一端与所述第一三极管Q1的基极相连；
所述第一三极管Q1的发射极接地，集电极与所述第一场效应管Q2的G极、所述第二电阻R2及所述第二场效应管Q3的G极相连，所述第二电阻R2与所述第一场效应管Q2的D极及所述第二场效应管Q3的D极相连，所述第一场效应管Q2的S极与所述电子烟电池的正极B+相连，所述第二场效应管Q3的S极与所述第三电阻R3及所述充放电共用端口的正极端口OUT+相连；所述充放电共用端口的正极端口OUT+还与所述充电管理模块相连；
所述第三电阻R3的另一端与所述第四电阻R4相连，所述第四电阻R4的另一端接地；所述微处理器U1与所述第三电阻R3及第四电阻R4相连，以获取所述充放电共用端口的电压。
优选的，所述充放电模块还包括第五电阻R5，所述充放电共用端口的负极端口OUT-与所述第五电阻R5相连，所述第五电阻R5的另一端接地；所述微处理器U1与所述充放电共用端口的负极端口OUT-及所述第五电阻R5相连。
当所述充放电共用端口处的采样电压小于第一预置电压，且所述开关K被触发时，所述微处理器U1获取所述第五电阻R5的电流。当所述微处理器U1确认所述第五电阻R5的电流大于预置电流时，控制所述充放电模块与所述电子烟电池断开，以停止为所述雾化器放电。这样，可以实现电子烟电池在为雾化器放电时的过流保护。
以下对图3所示的充放电模块的具体工作流程进行详细说明：
当充放电共用端口的正极端口OUT+和负极端口OUT-与雾化器连接时，在第三电阻R3和所述第四电阻R4相连处的电压接近零。与该第三电阻R3及第四电阻R4相连的微处理器U1的第“13”引脚确认检测到接收的采样电压小于第一预置电压，向微处理器U1输入低电平。当微处理器U1接收到第“13”引脚输入的低电平时，断开充电管理模块和充放电模块的连接，以避免充放电共用端口的正极端口OUT+的电能进入充电管理模块，进而避免给电子烟电池充电。
微处理器U1的第“5”引脚和第“9”引脚分别与开关K1的两端相连。当用户开始吸烟时，该开关K1被触发，使得微处理器U1的第“5”引脚和第“9”引脚相连通。开关K1被触发的方式有多种。具体举例来说，电子烟上设有物理按键，当用户要吸食电子烟时，通过按下该物理按键来触发K1；或者，电子烟内设有气流感应器，在用户吸食电子烟时，电子烟内的气压会产生变化，进而导致气流感应器的薄膜电容发生形变，当该薄膜电容的形变量达到阈值时触发该开关K1。当然，实际运用中还可以有其他方式来触发开关K1，在此不作限制。
当微处理器U1的第“13”引脚向微处理器U1输入低电平，且第“5”引脚和第“9”引脚相连通时，微处理器U1控制该微处理器U1的第“10”引脚向所述第一电阻R1输出高电平，使得第一三极管Q1导通，进而使得第一场效应管Q2和第二场效应管Q3导通，以使得充放电模块与电子烟电池导通，进而使得电子烟电池向充放电共用端口的正极端口OUT+输送电能。
当充放电共用端口的正极端口OUT+和负极端口OUT-与充电器连接时，与该第三电阻R3及第四电阻R4相连的微处理器U1的第“13”引脚确认检测到接收的采样电压大于第二预置电压，向微处理器U1输入高电平。
当微处理器U1接收到第“13”引脚输入的高电平，从第“10”引脚输出低电平，以关闭第一三极管Q1，进而关闭与所述电子烟电池的正极B+相连的第一场效应管Q2和第二场效应管Q3，以断开电子烟电池和充放电模块之间的连接，进而避免电子烟电池内的电能反灌到充电器内。
微处理器U1还控制与充放电共用端口的正极端口OUT+相连的充电管理模块与该正极端口OUT+相导通，以使得充电放电共用端口接收到的电能输入 到充电管理模块中，进而使得充电管理模块对电子烟电池进行充电。
微处理器U1还将第“13”引脚所接收到的采样电压通过显示模块显示出来，以方便用户查看充电输入电压。
优选的，当微处理器U1的第“13”引脚检测到接收的采样电压大于第三预置电压时，微处理器U1控制充电管理模块和充放电共用端口的正极端口OUT+之间断开，以避免电能进入充电管理模块，进而停止对电子烟电池的充电，实现充电过压保护。
优选的，当所述充放电共用端口处的采样电压小于第一预置电压，且所述开关被触发时，也就是充放电共用端口与雾化器连接且雾化器处于工作状态时，微处理器U1通过其第“7”引脚接收第五电阻R5的电流。
当微处理器U1检测到该电流大于预置电流时，微处理器U1的第“10”引脚输出低电平，以关闭第一三极管Q1，进而停止电子烟电池通过充放电共用端口向雾化器放电，实现过流及短路保护。
请参阅图4，图4是本实用新型的电子烟电池杆电路中充电管理模块的一个实施例的结构示意图。如图4所示，本实施例所示的充电管理模块具体包括第六电阻R6、第七电阻R7、第二三极管Q4、第三场效应管Q5、充电管理芯片U2；
所述第六电阻R6的一端与所述微处理器U1相连，另一端与所述第二三极管Q4的基极相连；
所述第二三极管Q4的发射极接地，集电极与所述第七电阻R7的一端、所述第三场效应管Q5的G极相连；
所述第三场效应管Q5的D极与所述第七电阻R7的另一端、所述充放电共用端口的正极端口OUT+相连，S极与所述充电管理芯片U2相连；
所述充电管理芯片U2还与所述微处理器U1和所述电子烟电池相连，以将所述电子烟电池的充电状态发送至所述微处理器U1。
以下对图4所示的充电管理模块的具体工作流程进行详细说明：
当充放电共用端口的正极端口OUT+和负极端口OUT-与雾化器连接时，即当微处理器U1接收到第“13”引脚输入的低电平时，微处理器U1的第“4”引脚输出低电平，以关闭第二三极管Q4，进而关闭第三场效应管Q5。由于第 三场效应管Q5的D极与充放电共用端口的正极端口OUT+相连，S极与充电管理芯片U2相连，因此微处理器U1关闭第三场效应管Q5可以断开充放电共用端口的正极端口OUT+和充电管理芯片U2的连接，进而避免给电子烟电池充电。
当充放电共用端口的正极端口OUT+和负极端口OUT-与充电器连接且充电器为电子烟电池正常充电时，即当微处理器U1接收到第“13”引脚输入的高电平时，微处理器U1的第“4”引脚输出高电平，以导通第二三极管Q4，进而导通第三场效应管Q5，使得充放电共用端口的正极端口OUT+输出的电能能够通过第三场效应管Q5输送至充电管理芯片U2，进而使得充放电管理芯片通过其第“2”引脚为电子烟电池充电。
充电管理芯片U2的第“1”引脚和第“5”引脚分别与微处理器U1的第“3”引脚和第“2”引脚相连。当充电管理芯片U2正在为电子烟电池充电时，充电管理芯片U2的第“1”引脚向微处理器U1的第“3”引脚输入信号，以向所述微处理器U1反馈电子烟电池处于充电中的状态。当充电管理模块将电子烟电池充满电时，充电管理芯片U2的第“5”引脚向微处理器U1的第“2”引脚输入信号，以向所述微处理器U1反馈电子烟电池处于充满电的状态。微处理器U1通过显示模块将电子烟电池的状态显示出来。
充电管理芯片U2的第“3”引脚还与微处理器U1的第“16”引脚相连，以使得电子烟电池能够为微处理器U1供电。优选的，充电管理芯片U2第“3”引脚与微处理器U1的第“16”引脚之间还设有稳压二极管(图未示)，以将电子烟电池输出的电压稳压到预定值再给微处理器供电。
请参阅图5，图5是本实用新型的电子烟电池杆电路中显示模块的一个实施例的结构示意图。本实施例中，显示模块具体为有机发光二极管(Organic Light-Emitting Diode，OLED)显示模块。如图5所示，本实施例所示的显示模块具体包括：
OLED屏、第八电阻R8、第九电阻R9、第十电阻R10、第十一电阻R11、第十二电阻R12、第三三极管Q6、第四三极管Q7和第五三极管Q8；
所述电子烟电池的正极B+与所述第八电阻R8的一端、所述第三三极管Q6的发射极相连，所述第八电阻R8的另一端与所述第三三极管Q6的基极、 所述第九电阻R9的一端相连，所述第三三极管Q6的集电极与所述OLED屏相连；
所述第九电阻R9的另一端与所述第四三极管Q7的集电极相连，所述第四三极管Q7的发射极接地，基极与所述第十电阻R10的一端、所述第十二电阻R12的一端相连，所述第十电阻R10的另一端接地，所述第十二电阻R12的另一端与所述OLED屏、所述第五三极管Q8的集电极相连；
所述第五三极管Q8的发射极与所述充电管理模块中充电管理芯片U2的第“3”引脚相连，基极与所述第十一电阻R11的一端相连，所述第十一电阻R11的另一端与所述微处理器U1相连。
以下对图5所示的显示模块的具体工作流程进行详细说明：
OLED屏的第“9”引脚、第“10”引脚、第“11”引脚分别和微处理器U1的第“11”引脚、第“17”引脚、第“18”引脚相连，使得微处理器U1分别通过该三条通道发送复位信号、时钟信号以及I2C数据。
微处理器U1的第“8”引脚与第十一电阻R11的一端相连，以控制电子烟电池开始和停止为OLED屏供电。
具体的，当微处理器U1需要OLED屏停止显示时，微处理器U1的第“8”引脚输出高电平，使得所述第五三极管Q8截止，因此所述第四三极管Q7的基极为低电平，使得所述第四三极管Q7截止，因此所述第四三极管Q7的集电极为高电平，使得所述第三三极管Q6截止，因此电子烟电池停止给OLED屏供电。
当微处理器U1需要OLED屏开始显示时，微处理器U1的第“8”引脚输出低电平，因此所述第五三极管Q8的集电极为高电平，进而所述第四三极管Q7的基极为高电平，因此所述第四三极管Q7处于放大导通状态，所述第四三极管Q7的集电极为低电平，使得所述第三三极管Q6导通，因此电子烟电池开始给OLED屏供电。
请参阅图6，图6是本实用新型的电子烟电池杆电路中电池电压采样模块的一个实施例的结构示意图。如图6所示，本实施例所示的电池电压采样模块具体包括第十三电阻R13和第十四电阻R14，其中所述第十三电阻R13的一端与所述电子烟电池的正极B+相连，所述第十三电阻R13的另一端与所述第 十四电阻R14的一端、所述微处理器U1相连，所述第十四电阻R14的另一端与所述微处理器U1相连。
以下对图6所示的电池电压采样模块的具体工作流程进行详细说明：
微处理器U1的第“6”引脚与所述第十三电阻R13和第十四电阻R14相连处相连，第“14”引脚与所述第十四电阻R14的另一端相连。
当微处理器U1需要采样时，第“14”引脚输出低电平，使得电流从电子烟电池的正极B+流出，并依次经第十三电阻R13和第十四电阻R14流向微处理器U1，再经微处理器U1流向接地点，然后再流回电子烟电池的负极。这样，第十四电阻R14的两端电压从微处理器U1的第“6”引脚反馈到微处理器U1中，由微处理器U1控制OLED屏显示电池电压。
优选的，当微处理器U1检测到电池电压低于预置数值时，还可以断开电子烟电池和充放电模块的连接以及关闭OLED屏，即关闭电子烟电池的输出。
当微处理器U1不需要采样时，第“14”引脚输出高电平，以降低第十三电阻R13和第十四电阻R14的功耗。
