优选的实施中，气溶胶生成制品100还设置有磁性材料103。磁性材料103包括铁、镍及含有它们的合金材质，或者永磁材料。
作为一可选的示例，磁性材料103可以是形成在气溶胶生成制品100的包装层的外表面上的涂层；或者，磁性材料103可以是气溶胶生成制
品100的包装层的一部分；或者，磁性材料103可以是设置在气溶胶生成制品100包装层的外表面上的磁性部件；在一优选的实施中，上述涂层或磁性部件被构造成环状结构。在另一优选的实施中，磁性材料103靠近气溶胶生成段102的下端设置。

电路30被配置为基于磁传感器50的输出信号，确定气溶胶生成制品100的温度，以控制加热器10的加热动作。例如：在气溶胶生成制品100中磁性材料103达到居里温度时，磁传感器50检测不到磁性材料103的磁场并输出一特征信号，电路30获取到该特征信号时，即可确定磁性材料103达到居里温度，进而确认气溶胶生成制品100加热到预设温度(该预设温度可以是居里温度，或者略大于居里温度)，此时即可控制加热器10降低功率输出或者停止加热。
电路30还可以基于磁传感器50的输出信号，判断磁性材料103的磁场强度是否低于阈值；当磁性材料103的磁场强度低于阈值时改变电源20的功率输出。或者，当磁性材料103的磁场强度低于阈值时控制停止加热器10工作。或者，控制加热器10的温度不超过磁性材料103的居里温度。
电路30还可以基于磁传感器50的不同输出信号，确定气溶胶生成制品100的不同温度。
由于磁性材料103在不同温度时会产生不同强度的磁场，磁传感器50的输出信号对应磁性材料103的磁场强度；因此可基于磁传感器50的不同输出信号，确定气溶胶生成制品100的不同温度。
需要说明的是，在加热器10配置为被变化的磁场穿透而发热时，为了避免磁场的干扰，电路30可先控制加热器10停止加热(时间非常短)，然后获取磁传感器50的输出信号；并基于磁传感器50的输出信号，确定气溶胶生成制品100的温度。在一些示例中，电路30被配置为间隙性地获取磁传感器50的输出信号，以确定气溶胶生成制品100的温度。在一些示例中，电路30控制电源20提供给加热器10可变磁场和获取磁传感器50的输出信号的动作是交替进行的，即电路30配置为在停止对加热器10提供可变磁场的。间隙期间来获取磁传感器50的输出信号
在加热器10采用电阻加热、红外辐射加热方式的情形下，电路30可直接获取磁传感器50的输出信号，并基于磁传感器50的输出信号，确定气溶胶生成制品100的温度。
请参考图4所示，与图3示例不同的是，在另一优选的实施中，支撑件40与腔室A沿着气溶胶生成装置的纵向方向依次排列设置。支撑件40位于腔室A的正下方并且靠近腔室A的底壁，支撑件40具有面向腔室A的上表面、以及背向腔室A的下表面。优选的，磁传感器50设
置在上表面上。
在另一示例中，气溶胶生成制品100可包括多个磁性材料103，多个磁性材料103可以具有不同的居里温度。磁传感器50能够检测到多个磁性材料103在不同情形下的磁场强度，例如：以两个磁性材料103为例，在其中一个磁性材料103在达到居里温度时的磁场强度，在两个磁性材料103均达到居里温度时的磁场强度等等。
在又一示例中，磁性材料103在不同温度时可以产生不同强度的磁场，因此磁传感器50可以检测到该磁性材料103的不同强度的磁场，进而确定其对应的温度。

步骤S10、获取磁传感器的输出信号；
