为了便于说明，以下示例针对加热元件既可以用来加热气溶胶形成基质，又可以作为用来感测实时温度的热敏元件，并结合图2进行说明：
图3示出了电路220一个实施例的基本组件的示意图。
如图3所示，电路220包括：
第一开关管Q1，定位于电芯210与加热元件103(图3中的R2所示)之间；当第一开关管Q1导通时，用于使电芯210对加热元件103提供电力；
采样电阻R1，定位于第二开关管Q2与加热元件103之间。具体地，采样电阻R1的第一端与第二开关管Q2连接、第二端与加热元件103连接；该采样电阻R1是阻值基本恒定的标准电阻，阻值范围介于0.1mΩ～1000KΩ，用于在当第二开关管Q2导通时与加热元件103形成串联，进而形成可以通过分压检测采样电阻R1和加热元件103的电压的检测回路。当然，在不需要进行检测时，第二开关管Q2断开以断开检测回路。
在图3中所示的具体实施中，加热元件103的第一端包括两路；其中第一路与第一开关管Q1连接，第二路用于与采样电阻R1形成串联。加热元件103的第二端是接地的，则加热元件103的第二端的电势为0。
进一步在图3所示的具体实施中，第一开关管Q1和第二开关管Q2是由控制器221控制通断的，并且第一开关管Q1和第二开关管Q2是不同时导通的。控制器221包括但不限于单片机MCU。在需要对加热元件103供电时，则控制器221控制第一开关管Q1导通、第二开关管Q2断开，使电芯210对加热元件103供电。在需要检测加热元件103的加热温度时，则控制器221控制第一开关管Q1断开、第二开关管Q2导通，通过检测回路、采样电阻R1、加热元件103的相关电特性例如电压，可以确定加热温度。
将采样电阻R1两端的电压记为V1，加热元件103两端的电压记为V2；检测的过程中，控制器221可以采样电阻R1的第一端即图3中采样点a1处的电压记为Va1，该电压即为检测回路两端的电压；采样加热元件103的第一端即图3中采样点b1处的电压Vb1。基于图3中加热元件103的第二端接地，则采样点b1处的电压Vb1＝V2，而采样电阻R1两端的电压V1＝Va1-V2。
基于上述的相关电特性，控制器221可以确定健值K，以通过该健值K，在预先存储的健值与加热温度的对应关系数据中，查找得到该健值K对应的加热温度。
具体地，可以通过以下不同方式实现：
1)、
其中，K值为
即为采样电阻R1两端的电压与加 热元件103两端的电压的比值；采样电阻R1为给定的标准电阻，阻值是恒定不变的；R2为加热元件103的体电阻；在建立健值与加热温度的对应关系数据时，需要根据TCR计算公式(若为单独的热敏元件可根据分度表)、并结合采样电阻R1的阻值，将
换算成对应的加热温度，从而可形成(K-T)温度表并存储在控制器221或者存储器中。之后，在确定健值K时，通过(K-T)温度表即可得到对应的加热温度。从该方式可以看出，无需计算出加热元件103的体电阻R2，即可得到对应的加热温度；另一方面，若VCC电压抖动变化，V
a1、
V
b1等电压值也同时等比例变化，不需要额外的滤波电路就能达到很好的抗干扰效果。需要说明的是，上述K值反之也是可行的，即采样电阻R1两端的电压与加热元件103两端的电压之间的比值包括K值为
2)、
其中，K值为
即为检测回路两端的电压与加热元件103两端的电压的比值；其它可参考方式1。
3)、
其中，K值为
即为检测回路两端的电压与采样电阻R1两端的电压的比值；其它可参考方式1。
进一步图4示出了电路220又一个实施例的基本组件的示意图；与图3示例不同的是，采样电阻R1与加热元件103(图中的R2所示)的位置交换了。
与图3类似的，可以通过以下不同方式确定健值K，进而确定加热温度：
11)、
K值为
即为加热元件103两端的电压与采样电阻R1两端的电压的比值。
12)、
K值为
即为检测回路两端的电压与采样电阻R1两端的电压的比值。
13)、
K值为
即为检测回路两端的电压与加热元件103两端的电压的比值。
进一步图5示出了电路220又一个实施例的基本组件的示意图；与图3示例不同的是，加热元件103的第二端不接地，控制器221采样或者检测加热元件103的第二端c3处的电压记为V
c3。
与图3类似的，可以通过以下不同方式确定健值K，进而确定加热温度：
21)、
其中，K值为
即为采样电阻R1两端的电压与加热元件103两端的电压的比值。
22)、
其中，K值为
即为检测回路两端的电压与加热元件103两端的电压的比值。
23)、
其中，K值为
即为检测回路两端的电压与采样电阻R1两端的电压的比值。
很容易想象得到的，与图4类似的，将图5中的采样电阻R1与加热元件103的位置交换，也可以确定对应的健值K，进而确定加热温度。
进一步图6示出了电路220又一个实施例的基本组件的示意图；与图3示例不同的是，采样电阻R1与加热元件103并联连接；控制器221a控制第一开关管Q1和第二开关管Q2同时导通时，采样电阻R1与加热元件103之间形成了检测回路；在不需要进行检测时，控制第二开关管Q2断开。
与图3类似的，可以通过以下不同方式确定健值K，进而确定加热温度：
31)、
其中，K值为
即为流经采样电阻R1的电流与流经加热元件103的电流的比值。
32)、
其中，K值为
即为流经加热元件103的电流与流经采样电阻R1的电流的比值。
在另一实施例中，控制器被配置为控制检测回路的电特性、采样电阻的电特性、热敏元件的电特性中的任意两个电特性的比值为预设值或者处于预设范围内。
具体地，基于图1所示的气溶胶生成装置，需要在不同阶段控制加热元件10的温度，例如：在预热阶段需要加热元件10的温度快速地达到最大温度，然后在最大温度下维持一段时间；在抽吸阶段或者恒温阶段，需要控制加热元件10的温度为预设值或者处于预设温度范围内。因此，通过控制器直接控制任意两个电特性的比值为预设值或者处于预设范围内，即可控制加热元件10的温度。以预热阶段为例，控制器可判断任意两个电特性的比值是否达到预设值，进而判断加热元件10的温度是否达到最大温度，从而控制电芯20向加热元件30提供电力。
在该实施例中，任意两个电特性的比值可参考图3-图6、以及前述内容的描述，在此不作赘述。
本申请另一实施方式还提供一种气溶胶生成装置的控制方法，气溶胶生成装置可参考前述内容。
所述方法包括：
根据检测回路的电特性、采样电阻的电特性、热敏元件的电特性中的任意两个电特性确定比值，确定加热气溶胶形成基质的温度。

步骤S11、控制第一开关管Q1断开并控制第二开关管Q2导通。
步骤S12、打开检测端口，检测采样点a1处的电压和采样点b1处的电压；其中，a1处的电压记为Va1，采样点b1处的电压记为Vb1。
