需要说明的是，加热器10的加热方式包括但不限于电阻加热、电磁加热、红外加热。作为示例性实施例，加热器10的形状包括但不限于针状、销钉状、管状或者薄片状。
还需要说明的是，与图1示例不同的是，在其他示例中，加热器10被构造成围绕至少部分气溶胶生成制品40进行加热，即通常所说的周向加热或者外围加热等等，也是可行的。
图2是本申请实施方式提供的气溶胶生成制品示意图。

图3是本申请实施方式提供的控制器示意图；图4是本申请实施方式提供的检测电路和开关管电路示意图。
在本示例中，控制器31、检测电路32以及开关管电路33集成在线路板30上。当然，集成在另一线路板也是可行的。控制器31采用MCU(Micro Controller Unit，微控制器单元)。可以理解的是，在其它示例中，控制器31可以采用专用集成芯片，或者其它具有处理器功能的芯片。
在本示例中，控制器31具有TEST_VCC端口、TEST_AIN端口、PWM_OUT_P端口以及PWM_OUT_N端口。
检测电路32包括电阻R2、电热C2，电阻R2、电容C2以及加热器10串联连接。具体地，电阻R2的一端与控制器31的TEST_VCC端口电连接，电阻R2的另一端与加热器10的一端(图中的WH+所示)电连接；加热器10的另一端(图中的WH-所示)与电容C2的一端以及控制器31的TEST_AIN端口电连接，电容C2的另一端与地连接。
开关管电路33包括开关管Q3、开关管Q5以及开关管Q7，在本示例中，开关管Q3和开关管Q7采用NMOS管，开关管Q5采用PMOS管。控制器31的PWM_OUT_P端口与开关管Q3的栅极电连接，开关管Q3的漏极与开关管Q5的栅极电连接，开关管Q3的源极接地；开关管Q5的源极与电芯20(图中的VBAT所示)电连接，开关管Q5的漏极与加热器10的一端(图中的WH+所示)电连接；PWM_OUT_N端口与开关管Q7的栅极电连接，开关管Q7的漏极与加热器10的另一端(图中的WH-所示)电连接，开关管Q7的源极接地；其它元器件及其电连接关系可参考图3所示。开关管电路33被配置为可导通或者断开加热器10与电芯20(图中的VBAT所示)之间的电连接。
在本示例中，控制器31被配置为输出控制信号以控制开关管电路33断开；在开关管电路33断开的情形下、且在定时器的定时时间到了之后，控制检测电路32有直流流通；根据电容C2两端的电位差达到预 设电位差阈值的持续时间，来确定气溶胶生成制品40接收于腔室A或者确定气溶胶生成制品40从腔室A移除，进而控制加热器10的动作。
具体地，控制器31可以控制PWM_OUT_P端口输出低电平使得开关管Q3断开，进而使得开关管Q5断开；同时控制PWM_OUT_N端口输出低电平使得开关管Q7断开；这样，使得加热器10与电芯20之间的电连接断开。
控制器31集成有定时器(附图未示出)，通过定时唤醒功能启动气溶胶生成制品40是否接收于腔室A的功能，以控制加热器10的动作，即控制加热器10启动或者停止加热。
控制器31可以控制TEST_VCC端口输出高电平，以使得检测电路32有直流流通。
如图4所示，加热器10可以等效于电阻R和电感L的串联，电阻R是一个固定值，而电感L的感量与气溶胶生成制品40是否接收于腔室A有关，即与气溶胶生成制品40插入腔室A有关。
检测电路32的线路阻抗可以通过以下公式来表示：
Figure PCTCN2022117905-appb-000001
其中，|Z|为线路阻抗，X L为电感L的感抗，X c2为电容C2的容抗。
电感L的感量变化会影响线路阻抗|Z|的大小，进而改变电容C2的充电时间。具体地，当气溶胶生成制品40插入腔室A时，具备磁性材料的气溶胶生成制品40可以使得电感L的感量增大，从而使得线路阻抗|Z|增大。
因此，在控制器31控制TEST_VCC端口输出高电平之后，气溶胶生成制品40未插入腔室A、与气溶胶生成制品40插入腔室A时，电容C2的前后充电时间是不同的；气溶胶生成制品40插入腔室A时电容C2的充电时间是大于气溶胶生成制品40未插入腔室A时电容C2的充电时间 的。
基于上述原理，可以根据电容C2两端的电位差达到预设电位差阈值的持续时间，来确定气溶胶生成制品40接收于腔室A或者确定气溶胶生成制品40从腔室A移除，进而控制加热器10的动作。
在本示例中，控制器31的TEST_AIN端口为中断端口，控制器31内集成有计时器(附图未示出)。
控制器31被配置为控制TEST_VCC端口输出高电平时，控制所述计时器启动计时；在电容C2两端的电位差达到预设电位差阈值时产生中断，以获取所述计时器的计时时间；根据所述计时器的计时时间，来确定气溶胶生成制品40接收于腔室A或者确定气溶胶生成制品40从腔室A移除，进而控制加热器10的动作。
在本示例中，预设电位差阈值为高电平，可以为电容C2充满时两端的电位差，也可以为低于电容C2充满时两端的电位差。
作为可选的实施方式，可以将电容C2两端的电位差达到预设电位差阈值的持续时间与预设时间阈值进行比较；
若电容C2两端的电位差达到预设电位差阈值的持续时间大于预设时间阈值，则可确定气溶胶生成制品40接收于腔室A，此时输出控制信号(例如方波信号)以控制开关管电路33工作，进而启动加热器10进行加热；
若电容C2两端的电位差达到预设电位差阈值的持续时间不大于预设时间阈值，则可确定气溶胶生成制品40未接收于腔室A，此时控制开关管电路33保持断开，即加热器10处于未加热状态。
其中，预设时间阈值可以设置为气溶胶生成制品40未接收于腔室A时，电容C2两端的电位差达到预设电位差阈值时的持续时间。
基于以上的判断，可以在气溶胶生成制品40插入腔室A时，自动 控制加热器10启动加热，无需按键操作，提升了用户体验。另一方面，在未具备磁性材料的气溶胶生成制品40插入腔室A时，线路阻抗|Z|的变化非常小，因此电容C2两端的电位差达到预设电位差阈值的时间几乎没有变化；此时，不会自动控制加热器10启动加热，可以起到防伪作用。
作为另一可选的实施方式，可以确定电容C2两端的电位差达到预设电位差阈值的持续时间与预设时间阈值的差值；若所述差值不大于预设差值阈值且大于零，则输出控制信号(例如方波信号)以控制开关管电路33工作，进而启动加热器10进行加热；若所述差值大于预设差值阈值或者所述差值小于等于零，则控制开关管电路33保持断开。
在该实施方式中，具备磁性材料的气溶胶生成制品40，由于磁性材料的一致性，可以使得气溶胶生成制品40插入腔室A时与气溶胶生成制品40未插入腔室A时的时间间隔是一定的。因此，通过确定电容C2两端的电位差达到预设电位差阈值的持续时间与预设时间阈值的差值在预设范围之内时，可以确定气溶胶生成制品40接收于腔室A，自动控制加热器10启动加热，无需按键操作，提升了用户体验。否则的话，若电容C2两端的电位差达到预设电位差阈值的持续时间与预设时间阈值的差值大于预设差值阈值，可以确定气溶胶生成制品40为伪造制品，此时不控制加热器10启动加热。进一步地，若电容C2两端的电位差达到预设电位差阈值的持续时间与预设时间阈值的差值小于等于零，可以确定气溶胶生成制品40未插入腔室A，此时也不控制加热器10启动加热。
在上述的二个实施方式中，若已控制加热器10启动加热，可以在加热器10处于加热间隙的情形下，再次启动气溶胶生成制品40是否接收于腔室A的判断。若气溶胶生成制品40插入腔室A，则继续加热；若 气溶胶生成制品40从腔室A移除，则停止加热。判断过程可参考前述实施方式。
需要说明的是，在本示例中，加热间隙指的是方波信号中相邻的两个高电平(或者低电平)之间的时间段。
还需要说明的是，与上述示例不同的是，在其它示例中，控制器31不通过中断的方式也是可行的，即TEST_AIN端口为一般端口。此时，控制器31在电容C2两端的电位差达到预设电位差阈值时，获取所述计时器的计时时间。后续的过程与前述类似，在此不作赘述。
