如图1所示，本申请实施例中提供了一种气溶胶产生装置，包括加热元件110、电源120、检测组件130及控制组件140。
其中，加热元件110用于加热气溶胶形成基质以产生气溶胶。加热元件110可以为一个发热丝，等效为一个电阻器。电源120与加热元件110电连接，用于向加热元件110输出电能，以使加热元件110加热。检测组件130分别与加热元件110、电源120电连接。控制组件140与检测组件130电连接，用于获取检测组件130的电性参数，根据预设的对应关系确定加热元件110的温度，并根据加热元件110的温度及预设的目标温度调节电源120为加热元件110提供的电能，以使加热元件110的实际温度保持在目标温度区间内。 其中，对应关系为检测组件130的电性参数与加热元件110的温度之间的对应关系。
检测组件130与电源120及加热元件110电连接。由于加热元件110在温度升高时，阻值也会上升，进而会使得与其电连接的检测组件130的电性参数发生变化。因此可以通过检测组件130的电性参数与加热元件110的温度之间的对应关系确定加热元件110的温度；再根据加热元件110的温度与预设目标温度来调节电源120为加热元件110提供的电能，以使加热元件110的实际温度保持在目标温度区间内。
在一个实施例中，检测组件130的电性参数可以是电阻值、两端电压、功率、电流等。本申请实施例中以检测组件130的两端电压为例进行说明。
在一个实施例中，控制组件140通过控制电源120向加热元件110输出的功率或者持续输出的时间，能够对加热元件110的加热温度进行控制，以使加热元件110维持在能够稳定雾化产生气溶胶的温度。可以理解的是，电源120还与加热元件110存在另一连接通路，即在不需要进行检测时，电源120通过该通路对加热组件进行供电。
加热元件110的阻值会随温度的变化发生改变。在温度升高时，加热元件110的阻值也会上升。控制组件140可以通过限制检测组件130的通电时间，保持检测组件130的阻值不变。基于分压原理，通过检测组件130两端的电压即可反映加热元件110的温度，根据检测组件130两端电压与预设的对应关系可以确定出加热元件110的温度。
需要说明的是，检测组件130与加热元件110及电源120的连接方式除了图1中所示出的将检测组件130设置于加热元件110与电源120之间之外，还可以将检测组件130设置于加热元件110与地之间，即任何能够将检测组件130与加热元件构成分压结构的连接方式都可以选择，并不限制于图1所示的连接方式。
上述气溶胶产生装置，通过设置检测组件130与加热元件110构成分压电路，由于检测组件130两端的电压取决于加热元件110的阻值与检测组件130的阻值，加热元件110在温度变化时，阻值也会随之变化，进而使得检测组件130两端的电压发生改变，因此可以通过检测组件130两端的电压与加热元件110的温度之间的对应关系确定加热元件110的温度，再根据加热元件110的温度与预设目标温度来调节电源120为加热元件110提供的电能，以使加热元件110的实际温度保持在目标温度区间内，由此能够实现精准温度检测。另外，相比于采用温度传感器进行温度测量的气溶胶产生装置，本申请提供的气溶胶产生装置的电路设计更为简单，成本也更低。与直接检测加热元件110的阻值进行温度检测相比，由于检测组件130不会受到温度影响，因此测量精度更高。
如图2所示，在一个实施例中，检测组件130包括：参考电阻RS及检测开关Q1。其中，检测开关Q1的第一端与电源120电连接，检测开关Q1的第二端与参考电阻RS的第 一端电连接，检测开关Q1的控制端与控制组件140电连接。参考电阻RS的第二端与加热元件110电连接。电性参数为参考电阻RS两端的电压。控制组件140用于获取参考电阻RS的第一端的第一电压V1以及参考电阻RS的第二端的第二电压V2，并根据第一电压V1、第二电压V2及对应关系确定加热元件110的温度；还用于控制检测开关Q1导通或断开，以实现检测模式的开启或关闭。
其中，电源输出的电压为VS。在需要进行检测时，控制组件140控制检测开关Q1导通，此时电源向串联的参考电阻RS和加热元件110提供电能(即电源电压VS)。控制组件140在此过程中获取参考电阻RS两端的电压，即第一电压V1和第二电压V2，而第一电压V1即为电源120的输出电压，因此第一电压V1会维持在相对稳定的电压范围内，而第二电压V2则会受到加热元件110阻值变化的影响；在第一电压V1未出现异常的情况下，第二电压V2可用于表征加热元件110的阻值，因此通过第一电压V1、第二电压V2及预设的对应关系可以确定加热元件110当前的温度。
在一个实施例中，控制组件140在检测模式下会获取多组第一电压V1与第二电压V2，筛除第一电压V1、第二电压V2各自的最大值和最小值后分别取平均值，最终采用第一电压V1的平均值和第二电压V2的平均值来确定加热元件110的温度，由此降低检测误差。
在需要关闭检测模式时，控制组件140控制检测开关Q1断开，切断参考电阻RS所在支路，此时电源120则通过另一支路为加热元件110供电。
在一个实施例中，若检测开关Q1的内阻与加热元件110的阻值量级相差不大，检测开关Q1与参考电阻RS以及加热元件构成串联分压，在加热元件110的阻值发生变化时，第一电压V1也会发生突变，此时采用第一电压V1和第二电压V2共同进行温度检测，依然能保证识别的准确性。
在一个实施例中，检测开关Q1可以采用三极管、MOS管、IGBT等电子开关。
在一个实施例中，检测组件130的电性参数还可以是参考电阻RS的阻值、参考电阻RS的功率或流过参考电阻RS的电流。
如图3所示，在一个实施例中，控制组件140包括功率开关Q2和控制器141。功率开关Q2的第一端与加热元件110连接，功率开关Q2的第二端与电源120电连接。控制器141分别与检测开关Q1的控制端、参考电阻RS、功率开关Q2的控制端电连接，用于获取参考电阻RS的第一端的第一电压V1以及参考电阻RS的第二端的第二电压V2，根据第一电压V1、第二电压V2及对应关系确定加热元件110的温度，并根据加热元件110的温度及预设的目标温度输出PWM信号至功率开关Q2。
其中，PWM信号用于控制功率开关Q2周期性地在导通和关断状态之间进行切换，以使 加热元件110的实际温度保持在目标温度区间内。控制器141通过改变PWM信号的占空比能够改变电源120的输出功率，从而调节加热元件110的温度，根据第一电压V1、第二电压V2及对应关系确定加热元件110的温度；在加热元件110的温度低于预设的目标温度时，则调节PWM信号，增大电源120的输出功率，提高加热元件110的温度；在加热元件110的温度高于预设的目标温度时，则调节PWM信号，降低电源120的输出功率，降低加热元件110的温度，由此实现精准控温。
在一个实施例中，控制器141用于在PWM信号控制功率开关Q2处于关断状态时，控制检测开关Q1导通，并获取第一电压V1和第二电压V2，以确定加热元件110的温度。
在功率开关Q2导通时，第二电压V2会被上拉，无法实现检测，因此需要在功率开关Q2关断时进行检测，为了不影响正常雾化，可以利用功率开关Q2受PWM信号控制处于关断状态时，控制检测开关Q1导通实现检测。
在一个实施例中，该对应关系为：
T＝K*V2(V1-V2)+b；
其中，T为加热元件110的温度；K为预设的温度系数；V1为第一电压，V2为第二电压；b为预设的修正常数。
温度系数K和修正常数b通过与预先校准的方式进行预设，可以在生产阶段实现。具体地，测量加热元件110在加热过程中的多个温度值，并记录每个温度值对应的第一电压V1和第二电压V2，根据上述关系式计算出温度系数K和修正常数b，实现预设。
