在该加热过程中，有利于在第一时间阶段快速地使加热元件50的第一区段51加热，从而快速地向过滤吸嘴输出气溶胶；以及在第二时间阶段加热加热元件50的全部区段，即同时加热第一区段51和第二区段52，有利于保持气溶胶输出的量或口感均匀。尤其是在第二时间阶段随着加热过程的进行，气溶胶生成制品中的可汽化材料含量下降时，第一部分41和第二部分42同时产生磁场诱导加热元件50的全部区段发热，可以在抽吸过程中维持气溶胶量的前后一致性。
在该加热过程中，第一时间阶段和第二时间阶段是间隔的。例如在一些实施例中，第一时间阶段和第二时间阶段之间间隔有10～20s；例如当在第一时间阶段通过控制感应线圈40的第一部分41产生变化的磁 场以单独地诱导加热元件50的第一区段51加热之后，间隔10～20s后再启动第二时间阶段的同时感应线圈40的第一部分41和第二部分42诱导加热元件50的第一区段51和第二区段52加热。
在该控制过程中，步骤S200阶段中感应线圈40的第一部分41和第二部分42同时产生磁场进行加热时，第二部分42的功率是与第一部分41存在相关关系的；则通过温度传感器71检测加热元件50的第一区段51的温度变化，即可反向确定第一部分41输出给的第一区段51能量；进一步再基于第二部分42的功率与第一部分41的关联性或相关性，即可进一步估算加热元件50的第二区段52的温度变化。从而在步骤S200的过程中，通过温度传感器71的感测结果，进而估算确定第二区段52的温度；对于在硬件上省略或节约布置于第二区段52的温度传感器72的成本是有利的。
图5示出了又一个变化实施例的电路的示意图，在图5所示中电路仅具有电容C1，电容C1用于与感应线圈40的第一部分41和/或第二部分42组成LC振荡器；在该图5所示的实施例中，仅具有电容C1的LC振荡器是非对称半桥的LC振荡器。同样的在图5所示的实施例中，电路能通过选择性地导通第一开关S1和第二开关S2中的一个或两个，从而选择性地驱动感应线圈40的第一部分41和第二部分42中的一个或两个产生磁场。
作为图5所示电路的振荡控制过程的示例，气雾生成装置中的控制器被配置为：在第一时间阶段导通第一开关S1和第二开关S2中的一个，即可将第一部分41和第二部分42中的一个与电容C1串联组成LC振荡器，以使第一部分41或第二部分42单独地产生变化的磁场；而在第二时间阶段同时导通第一开关S1和第二开关S2中的两个，第一部分41和第二部分42并联后再与电容C1串联组成LC振荡器，以使第一部分41和第二部分42同时产生变化的磁场。图6示出了又一个实施例的感应线圈40a的示意图，在图6所示的实施例中，感应线圈40a包括：
第一螺旋线圈41a，基本是与加热元件50的长度相近的；第一螺旋线圈41a包括沿轴向方向依次布置的第一部分411a和第二部分412a；其中，第一部分411a围绕加热元件50的第一区段51、以及第二部分412a围绕加热元件50的第二区段52；
第二螺旋线圈42a，围绕加热元件50的第一区段51布置，并且避开加热元件50的第二区段52。
第一螺旋线圈41a的长度是显然地大于第二螺旋线圈42a的长度的。
在图6中所示，加热线圈40a还包括：
第一连接抽头431a、第二连接抽头432a和第三连接抽头433a；其中，第一螺旋线圈41a连接或布置于第一连接抽头431a和第三连接抽头433a之间；第二螺旋线圈42a连接或布置于第一连接抽头431a和第二连接抽头432a之间。或者在图6中所示，第一螺旋线圈41a和第二螺旋线圈42a的一端同时焊接于第一连接抽头431a上，或者第一螺旋线圈41a和第二螺旋线圈42a的一端公用第一连接抽头431a。
在该图6的实施例中，第一螺旋线圈41a和第二螺旋线圈42a是同时基本均匀地缠绕在管状支架30外的；以及，第一螺旋线圈41a和第二螺旋线圈42a的直径或单位长度的匝数是相同的。
相应地，电路中分别使第一螺旋线圈41a和第二螺旋线圈42a分别各自组成LC振荡器，从而各自根据需要地引导交变电流流过第一螺旋线圈41a和第二螺旋线圈42a。具体地，电路在感应线圈40a的控制过程如图9所示，可以包括：
S100a，在第一时间阶段，通过第一连接抽头431a和第二连接抽头432a在第二螺旋线圈42a上引导交变电流，从而仅使第二螺旋线圈42a产生磁场以单独地诱导加热元件50的第一区段51形成涡流发热；
S200a，在第二时间阶段，通过第一连接抽头431a和第三连接抽头433a在第一螺旋线圈41a上引导交变电流，进而第一螺旋线圈41a产生磁场，以同时地诱导加热元件50的第一区段51和第二区段52形成涡流发热。相近地在该加热过程中，第一时间阶段和第二时间阶段是间隔的；例如在一些实施例中，第一时间阶段和第二时间阶段之间间隔有10～20s。
以上加热过程的S100a和S200a切换的前后，由于第二螺旋线圈42a和第一螺旋线圈41a具有不同的电感量，从而它们分别具有不同的谐振频率；则相应地在实施例中，电路可以包括由第一螺旋线圈41a和电容组成的第一LC振荡器，以及由第二螺旋线圈42a与电容组成的第二LC振荡器；以及，由于第二螺旋线圈42a和第一螺旋线圈41a具有不同的电感量，则第一LC振荡器和第二LC振荡器具有不同的谐振频率。则相应地，电路配置为：
在第一时间阶段中按照预设的第一驱动频率驱动第二LC振荡器振荡，从而形成流过第二螺旋线圈42a的交变电流；以及在第二时间阶段改变为按照预设的第二驱动频率驱动第一LC振荡器振荡，从而形成流过第一螺旋线圈41a的交变电流。其中，第一驱动频率和第二驱动频率不同。
或者在又一些变化的实施例中，电路可以具有谐振频率检测模块， 以在控制加热的过程中的S100a的第一时间阶段和S200a的第二时间阶段跟踪监测当前的谐振频率，并根据实时检测的谐振频率的结果来反馈调整输出的驱动频率，以在第一时间阶段中根据检测的第二LC振荡器振荡的谐振频率输出相同的驱动频率驱动第二LC振荡器振荡；以及在第二时间阶段中根据检测的第一LC振荡器的谐振频率输出相同的驱动频率驱动第一LC振荡器振荡。
或者图7示出了又一个变化实施例中第一螺旋线圈41b独立地通过两端焊接的第一连接抽头431b和第二连接抽头432b供应交变电流从而产生磁场；以及，第二螺旋线圈42b通过两端焊接的第三连接抽头433b和第四连接抽头434b供应交变电流从而产生磁场。在该实施例中，可以相近地在第一时间阶段使第二螺旋线圈42b诱导加热元件50的第一区段51形成涡流发热，以及在第二时间阶段使第一螺旋线圈41b产生磁场，进而同时诱导加热元件50的第一区段51和第二区段52形成涡流发热。
