具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明中提供了一种电子烟的可充电电源保护装置及方法 ，可以理解的是，在对电子烟进行充电的过程中，会出现以下情况。
一：充电电路短路，可以理解的是对电子烟进行充电的过程是将电子烟烟的电池杆旋于充电单元中，电池杆旋入充电单元的部分很容易发生短路，或者是充电单元发生故障，充电单元内部的短路也会造成内置于电池杆的充电电路短路，对电源模块造成损坏。
二：充电电路接入负载，可以理解的是，电子烟时包含电池杆、雾化器，电池杆与雾化器通过螺纹旋合的方式进行连接，当对电池杆中的电池进行充电时，若接入了雾化器则会成为充电电路的负载；再者当充电单元本身发生故障，此故障使得充电单元本身相当于一个电阻，若接入充电电路则相当于一个负载。同时，可以理解的是，使充电电路短路以及产生负载的情况并不限定于上述的情况。
如图1所示，本发明提供的一种电子烟的可充电电源保护装置，包括可充电的电源模块110，微控制器100、半导体开关120、用于接入充电单元的接口模块130；接口模块130具有第一充电端子131以及第二充电端子132；微控制器100具有输入端104以及输出端105；电源模块110与接口模块130以及半导体开关120相连，通过接口模块130接入充电单元为电源模块110充电；电源模块110与微控制器100相连，向微控制器100提供电源；微控制器100的输入端104以及输出端105分别与接口模块130以及半导体开关120相连，检测第一充电端子131的电压信号，判断所述电压信号电平的正负；并向半导体开关120发送控制信号控制半导体开关120的通断。
微控制器100包括模数转换器102、判断模块101、控制模块103；控制信号包括断路控制信号以及通路控制信号，断路控制信号用于控制半导体开关120的断开，通路控制信号用于控制半导体开关120的闭合。
模数转换器102，检测电压信号并由模拟信号转换为数字信号；判断模块101与模数转换器102相连，判断所述电压信号电平的正负，并将正电平以及负电平信号发送至控制模块103；控制模块103，根据判断值向半导体开关120发送控制信号。
电压信号的电平为负电平时，控制信号为通路控制信号，控制半导体开关120导通；电压信号的电平为正电平时，控制信号为断路控制信号，控制半导体开关120断开。
微控制器为CPU、GPU、MCU或者 ASIC 芯片，但不仅仅限于上述的微控制器的的类型。
通过检测第一充电端子131的电压的电平正负，则可以检测出由充电接口接入的充电单元、负载所发生的短路情况，之后通过微控制器100控制半导体开关120通断以起到对电源模块的保护作用。
第一充电端子131用于接入充电单元的负极，第二充电端子132用于接入充电单元正极。
本发明中，微控制器100的输入端104与第一充电端子131进行连接，第二充电端子132与电源模块的正极相连；微控制器100的输入端104检测电压信号时。
本发明中接口模块130还包括第一电阻140，第一电阻140并联在第一充电端子131以及第二充电端子132的两端；该电阻用于微控制器100输入端的电压检测 ，可以理解的是，该第一电阻140还可以使具有阻值的其它器件。
则通过本发明的这样的电路结构，如图2所示，当充电接口悬空，微控制器输出端105不输出，此时半导体开关处于断开状态，控制器输入端104的电平为高电平（正电平）。
当充电接口接入充电单元时， 微控制器的输入端 104 为低电平也为负电平，具体 如图3所示，第一电阻140与充电单元形成一回路，微控制器100的输入端104连接于第一充电端子131（与充电单元的负极相连），此时微控制器100的输入端104的电压即为充电单元负极的电压。微控制器100的输入端104检测到该负电平后，微控制器100发出通路控制信号控制半导体开关120导通。此时充电电路导通，电源模块110处于充电状态。
如图4所示当充电接口两端短路或接入负载时，且充电电路处于断开状态时，如上所述，微控制器100的输入端104检测到的电压为电源模块110的正极的电压，则该检测电压为正电平，该充电回路仍然处于断开。
当充电接口两端短路或接入负载时，且充电电路处于导通状态时，在瞬间，半导体开关120仍然处于闭合状态，此时电源模块110为负载（电阻或其他有阻值的器件）提供电源，此时经流半导体开关120的电流方向反相，微控制器100的输入端的电压的电平变化，此时检测电压相对于在充电状态有一个由负电平变为正电平。该正电平信号由微控制器100的输入端104传送到微控制器100中，微控制器100发出断路控信号控制半导体开关120断开，则防止了电源模块110的放电。
可以理解的是，在微控制器100（判断模块中）中预设有一参考电压，通过将检测的电压信号的值与参考电压值比较，当检测的电压大于参考电压时，该电压为正电平，当检测的电压小于参考电压时，该电压为负电平。
优选的，本发明中参考值时以在充电状态下导通的半导体开关120两端的电压为参考电压。
进一步的，当检测电压为负电平，则判断模块101驱动控制模块103向半导体开关120施加一导通电压以控制半导体开关120导通，当检测电压为正电平时，且此时半导体开关120处于导通状态，则判断模块101驱动控制模块103向半导体开关120施加该导通电压的反向电压来使半导体开关120关闭。
优选的，半导体开关120为 MOSFET 管， MOSFET 管的栅极与微控制器100的输出端105相连。可以理解的是，并不限于MOSFET的种类，可以为N沟道 MOSFET 管或P沟道 MOSFET 管。
当 MOSFET 管为N沟道 MOSFET 管时，控制模块103提供的导通电压大于Ugs，当 MOSFET 管为P沟道 MOSFET 管时，控制器提供的导通电压小于-Ugs。
综上，通过本发明的电子烟的可充电电源保护装置可对可充电电源模块进行短路及放电保护。
本发明还涉及一种电子烟的可充电电源保护装置及方法：当接口模块接入充电单元进行充电时，包含以下步骤：
S1 ：微控制器100检测第一充电端子131的电压
S2 ：判断电压电平的正负，若为负电平，则执行步骤S3，若为正电平，则执行步骤S4;
S3 ：微控制器100控制半导体开关120导通；
S4 ：所述微控制器100控制所述半导体开关120断开。
步骤S2还包括，
S21 ：将检测的电压转换为数字信号；
S22 ：判断模块101判断电平为负电平时，执行步骤S23，为正电平时，则执行步骤S24;
S23 ：控制模块103向半导体开关120发送通路控制信号；
S24 ：控制模块103向半导体开关120发送断路控制信号。
可以理解的是，判断模块中预设有一参考电压，在步骤S22中，但检测的电压值大于参考电压时，则为正电压，检测的电压值大于参考电压时，则为负电压。
接口模块130还具有第二充电端子132以及第一电阻，第一电阻140并联在第一充电端子131以及第二充电端子132两端。
虽然本发明是通过具体实施例进行说明的，本领域技术人员应当明白，在不脱离本发明范围的情况下，还可以对本发明进行各种变换及等同替代。另外，针对特定情形或材料，可以对本发明做各种修改，而不脱离本发明的范围。因此，本发明不局限于所公开的具体实施例，而应当包括落入本发明权利要求范围内的全部实施方式。
