 本发明的最佳实施方式
请参阅图1所示，本发明防止重复注液使用的电子雾化设备，包括可拆卸连接的电源装置A和雾化器B，电源装置A包括电池A1和控制电路A2，控制电路包括启动开关2，启动开关2用于检测用户的抽吸动作并控制功率控制模块3的功率输出。本实施例启动开关2为一种按键开关，用户抽吸时手动按动该开关。在其它实施例中，启动开关2还可以是咪头开关、或气压传感器、或气流传感器，这些开关可以自动检测用户的抽吸动作。雾化器B包括存储雾化液的储液腔B1、雾化电阻5及与控制电路电性连接的ID芯片6。
请参阅图2所示，控制电路A2包括电性连接的微控制器1、启动开关2、功率控制模块3和雾化液消耗统计模块4，微控制器1读取ID芯片6内存储的数据以及将数据写入到ID芯片6内。ID芯片6包括识别码存储模块61和累计数存储模块62，识别码存储模块61用于存储代表雾化器唯一身份编码的识别码，每个不同的雾化器，其识别码都是不同的，该识别码需要通过预设的特殊动态加密算法才可以被微控制器识别，难于被破解。累计数存储模块62用于动态存储雾化液消耗累计数；启动开关2用于检测用户的抽吸动作并控制功率控制模块3的功率输出，功率控制模块3输出功率给雾化电阻5，雾化电阻5通电工作将雾化液进行雾化，雾化液消耗统计模块4模拟计算雾化液的消耗量并通过微控制器1将雾化液的消耗量或模拟消耗量累加到累计数存储模块62。雾化器B中设有ID芯片6，不同的ID芯片6存储有不同的识别码，微控制器可以通过预设的算法识别ID芯片内储存的动态的识别码，通过判别该识别码的正确性就可以对雾化器进行真假识别以及区分每一个正品雾化器。
本实施例的控制电路配置为：雾化器B和电源装置A连接后，微控制器1自动读取雾化器B的识别码和雾化液消耗累计数，并在辨别出不正确的识别码、或辨别出正确的识别码但比较得出雾化液消耗累计数超过预设的雾化液消耗总数时，关闭功率控制模块3的输出，禁止该雾化器继续工作。
请参阅图2所示，ID芯片6还包括读写控制模块63，ID芯片6采用两线制与雾化电阻5共享正负电极，并通过读写控制模块63与微控制器1进行数据通信。
雾化液的消耗统计，可以通过如下多种方法实现：
一种是直接通过传感器检测雾化器的储液腔中雾化液的减少，如液位的减少来统计雾化液的消耗。
一种是通过统计吸烟或吸雾的口数来模拟统计雾化液的消耗量，在正常情况下，每吸一口烟雾会平均消耗一定量的雾化液，储液腔中储存的一定量的雾化液，可以吸一定的口数，因此口数与雾化液的消耗量具有一定的比例关系。由于每吸一口烟雾，启动开关都会工作一次，因此可以统计启动开关的次数来统计口数。
一种是通过统计每吸一口烟雾的时长以及累计时长来模拟统计雾化液的消耗量，在正常情况下，一定时长内消耗的雾化液基本是相同的，因此启动开关工作的时长即吸烟雾的时长与雾化液的消耗量具有一定的比例关系。用户每口吸烟雾的时长是不同的，因此统计时长相对于统计口数具有更准确的对应关系。
一种是通过统计雾化电阻的功耗来模拟统计雾化液的消耗量，雾化液消耗时，从液体变成雾状或汽态，需要消耗一定的热能或电能，即雾化电阻的功耗，故雾化电阻的功耗与雾化液的消耗量具有一定的比例关系。雾化电阻的功耗=功率控制单元的输出功率×启动开关工作时长累计数。
本实施例中，雾化液消耗统计模块4包括计时器41，计时器41统计启动开关2工作时长，雾化液消耗累计数为启动开关2工作时长累计数。
在其它实施例中，计时器可由口数计数器或能量计数器替代，其中口数计数器统计启动开关2的工作次数，能量计数器统计雾化电阻5的消耗能量即功率控制模块3输出功率与启动开关2工作时长的乘积数，雾化液消耗累计数即为口数累计数，或为启动开关2工作时长累计数，或为雾化电阻5的消耗能量累计数。
在另一实施例中，雾化器B还包括检测雾化液的液位传感器（图中未示），雾化液消耗统计模块4包括液位计量器，液位计量器统计雾化器B工作时的液位减少量，雾化液消耗累计数为液位减少量累计数。
预设的雾化液消耗总数为相当于一只雾化器可存储的雾化液的总量，这样，当用户消耗完一只雾化器内的全部雾化液时，即使私自重新注入雾化液，也不能进行使用。预设值是根据雾化液成分、储液腔内的容积及每口吸雾或吸雾时长的雾化液损耗量的统计值进行设定的。
请参阅图3所示，微控制器1包括MCU芯片，MCU芯片包括28个引脚，其中第3引脚连接VDD信号端用于给MCU芯片供电，第4引脚接地，第5引脚连接MCU-RST信号端用以输入MCU复位信号，第6引脚连接RES-DET1用以输入雾化电阻5的检测模拟信号1，第7引脚连接RES-DET2用以输入雾化电阻5的检测模拟信号2，第22引脚连接MIC-DET信号端用以输入启动开关2的工作信号，第23引脚连接DAT-EN信号端用以输出读写ID芯片6的上拉控制信号，DAT-EN信号端还连接上拉电阻R1的一端，上拉电阻R1的另一端连接雾化电阻5与ID芯片6的共享端即PWM-OUT/WR/RD信号端，第24引脚连接Res-DET-EN信号端用以输出测电阻的使能开关信号，第28引脚连接PWM信号端用以输出功率控制模块3的使能开关信号。
请参阅图4所示，ID芯片6设有两个引脚，其中一引脚连接PWM-OUT/WR/RD信号端，PWM-OUT/WR/RD信号端与雾化电阻的功率输出端共用，另一引脚连接GND接地信号端，读写控制模块63、识别码存储模块61和累计数存储模块62并联连接。读写控制模块63包括电阻R2和MOS管Q1，电阻R2的一端同时与MOS管Q1的栅极G和PWM-OUT/WR/RD信号端连接，电阻R2的另一端与MOS管Q1的源极S连接，MOS管Q1的漏极D与GND接地信号端连接。
