以下结合图2-图8，对本申请一优选的实施方式进行说明：
如图2所示，气溶胶生成装置10包括加热器101、控制器102和电芯103。
加热器101用于根据电芯103提供的电力产生热量，以对放置于气溶胶生成装置10中的制品20进行加热，使制品20中的气溶胶形成基质产生气溶胶，供用户抽吸。
在图2的示例中，加热器101构造成外围或者周向加热结构(加热器101包围至少部分气溶胶形成基质)，加热方式可以为电阻加热、红外辐射加热、电磁加热等等。
控制器102分别与加热器101和电芯103连接，用于控制电芯103供给至加热器101的电力或者输出功率给加热器101，进而控制加热器101的加热温度，以使得加热气溶胶形成基质产生气溶胶。
控制器102还配置为用于执行气溶胶生成装置10的控制方法。
气溶胶生成装置10还可包括用于存储执行气溶胶生成装置10的控制方法的程序的存储介质，控制器102可读取并执行所述存储介质中存储的气溶胶生成装置10的控制方法的程序，实现气溶胶生成装置10的控制方法。存储介质可以为设置在气溶胶生成装置10中的独立存储器件，也可以是内置于控制器102中的存储介质。存储介质包括但不限于非易失性的存储介质。
电芯103，即功率源，用于给加热器101和控制器102提供电力。电芯103可以为可充电电芯，也可以为不可充电电芯。
在图2的示例中，气溶胶生成装置10还包括耦接在加热器101与电芯103之间的调压电路104；调压电路104包括升压电路和/或降压电路。例如：图5和图8所示的BUCK-BOOST变换电路，图6所示的BOOST变换电路，图7所示的BUCK变换电路、CUK变换电路(未示出)、ZETA变换电路(未示出)、SEPIC变换电路(未示出)中的至少一种。
调压电路104包括开关管，通过控制调压电路104中开关管的占空比和/或开关频率，可以调整供给至加热器101的电力信号的电压，以使得流经加热器101的电流变化量保持在预设范围，进而控制气溶胶生成装置10产生的噪音分 贝值。
可以根据加热器101的实时温度，调整供给至加热器101的电力的电压。加热器101的实时温度可通过与控制器102连接的温度传感器(图中未示出)检测得到。温度传感器包括但不限于热电偶、具有电阻温度系数的温度检测模块。优选的实施中，加热器101本身可具有电阻温度系数，通过加热器101的电阻值可确定加热器101的实时温度。
在本示例中，供给至加热器101的电力的电压波形包括但不限于方波、三角波、锯齿波。
如图3所示的加热器的温度曲线示意图，其中，温度曲线的横坐标t表示时间，纵坐标T表示温度。
t0时刻，加热器101的初始温度为T0。
在图3示例中，初始温度大于环境温度；其它示例中，初始温度可以为环境温度。
t0～t1时间段，控制器102控制加热器101的电力以最大功率或者其它预设功率进行加热，例如：最大功率为36W；在t1时刻，加热器101加热到预设温度T1。
预设温度可以为气溶胶形成基质产生气溶胶的最佳温度，即气溶胶形成基质在该温度下可以提供最适合用户抽吸、口感较佳的烟雾量及温度。本申请实施方式采用的预设温度介于150℃～350℃；或者，介于180℃～350℃；或者，介于220℃～350℃；或者，介于220℃～300℃；或者，介于220℃～280℃；220℃～260℃。
t1～t2时间段，控制器102控制电芯103供给至加热器101的电力并控制加热器101在预设温度T1(220℃)下保持一段时间(即t1～t2时间段)。需要说明的是，在其它示例中，不设置t1～t2时间段也是可行的。
t2时刻，控制器102可输出抽吸气溶胶的提示信号，提示用户抽吸。具体地，可通过与控制器102连接的提示装置，根据控制器102输出的可抽吸气溶胶的提示信号执行提示操作。例如：提示装置为震动马达，震动马达根据控制器102输出的可抽吸气溶胶的提示信号(包括用于控制震动马达工作的启动信号)，震动提示用户可抽吸气溶胶；提示装置为LED灯，LED灯根据控制器102输出的可抽吸气溶胶的提示信号，常亮或闪烁提示用户抽可抽吸气溶胶。
t2～t3时间段，在输出可抽吸气溶胶的提示信号之后，控制器102控制电芯103供给至加热器101的电力并控制加热器101的温度从T1下降到目标温度T2。随后，控制器102控制电芯103供给至加热器101的电力，以控制加热器101维持在目标温度T2。
其中，t2～t3时间段的值可以为120秒～360秒或者抽吸6口～20口的的时长。
如图4所示，t2～t3时间段，供给至加热器101的功率的电力参数包括交替性提供的第一电力参数和第二电力参数，在图4所示的实施中，第一电力参数和第二电力参数包括电压，功率源所提供的电压波形为方波。在该方波中，功率源所提供的电压包括第一电压和第二电压，且第二电压小于第一电压。例如第一电压Vmax为供给至加热器101的电力的最大电压值，第二电压Vmin为供给至加热器101的电力的最小电压值。为了控制气溶胶生成装置10产生的噪音分贝值在用户可接受的范围，Vmax和Vmin满足以下关系：
(Vmax-Vmin)/RX＝I V，其中RX为加热器101的阻值，I V为电力信号的电流变化量，其预设范围介于0～5A；或者，介于0～4A；或者，介于0～3A；或者，介于0～2A；或者，介于0～1A；或者，介于0～0.5A；或者，介于0～0.2A。在加热器101的阻值一定时，供给至加热器101的电力的电压变化量也是处于对应的预设范围。
如图5所示的具体电路示意图，电芯103(图中的BAT所示)与加热器101(图中的OUT+与OUT-即为加热器101)之间耦接有异步降压电路和BOOST升压电路。
以图4的t0～t1时间段为例，开关管Q3导通，异步降压电路不工作，由开关管Q7和开关管Q6构成的BOOST升压电路工作，输出高于电芯103电压幅度的直流电压；使得加热器101加热到预设温度T1。
当加热器101加热到预设温度T1时，可以控制开关管Q6导通，开关管Q7关断，即BOOST升压电路停止工作；然后通过控制器102控制开关管Q14使得开关管Q3输出PWM脉冲信号，从而使得由开关管Q3、二极管D7、电感L1、开关管Q6、电热C12和C9组成的异步降压电路，加载在加热器101上的电力的电压下降，温度随之也下降。在加热器101的温度从T1下降到T2时，由于此时的电压不能使加热器101的温度呈上升趋势，所以需要再次打开BOOST升压电路，使加热器101的温度呈上升趋势，达到设定的温度值T2。在t2～t3时 间段，BOOST升压电路与异步降压电路交替工作，控制供给至加热器101的电力的电压，以使得流经加热器101的电流变化量保持在预设范围，抑制加热器101在变化电流作用下所产生的变化磁场环境下所产生机械振动的幅度，进而控制气溶胶生成装置10产生的噪音分贝值。

Figure PCTCN2022122825-appb-000001
从以上测试结果可以看出，在流经加热器101的电流变化量介于1A～5A时，虽然可以听到滋滋声，但是测试分贝处于用户可接受的范围(安静范围)；在流 经加热器101的电流变化量介于1A以下时，贴近人耳几乎听不到声音，用户体验感最佳。随着流经加热器101的电流变化量的降低，测试的分贝值也是相应的降低。
以下结合图9至图12，对本申请另一优选的实施方式进行说明：
如图9所示，与图2示例不同的是，气溶胶生成装置100中的加热器1001构造成中心加热结构(加热器的外周与气溶胶形成基质直接接触)，加热方式不作限定。气溶胶生成装置100中的控制器102、电芯103与前述类似。
在图9所示的实施中，加热器1001是构造成细长形状的加热器以可以插入气溶胶形成基质中。作为一种示例，加热器1001包括细长的加热器基体和结合在加热器基体上的电阻加热元件，电阻加热元件在流经电流时能够产生热量；电芯103通过控制器102与加热器1001的电阻加热元件连接，气溶胶生成装置100中的控制器102可以在该电阻加热元件流经变化的电流时，通过合适的电力参数来输出功率来抑制加热器1001机械振动的幅度或频次，从而使得所述加热器的噪音分贝值保持在较低水平。其中，电芯103可以作为功率源。
如图10所示，作为另一示例，加热器还可以是包括与功率源连接的感应线圈1003和与感应线圈1003电磁耦合的感应加发热体1002，感应加发热体1002在感应线圈1003产生的变化磁场下发热以加热气溶胶形成基质，电芯103通过控制器102与感应线圈1003连接，气溶胶生成装置中控制器102能够以合适的电力参数输出功率给感应线圈1003，例如通过合适的频率提供给所述感应线圈变化电流，从而抑制感应线圈1003的振动使其噪音分贝值保持在较低水平。其中，电芯103可以作为功率源。
气溶胶生成装置100还包括耦接在加热器1001与电芯103之间的开关电路1004；如图11所示，开关电路1004包括开关管Q2和开关管Q1；开关管Q2和开关管Q1均包括输入连接端、输出连接端以及控制端。在本示例中，开关管Q2为NMOS管，开关管Q1为PMOS管；开关管Q2的输入连接端为漏极，输出连接端为源极，控制端为栅极；开关管Q1的输入连接端为源极，输出连接端为漏极，控制端为栅极。开关管Q2的控制端用于接受控制器102的控制，以导通或者断开电芯103与加热器1001之间的电连接。开关管Q2的输入连接端与开关管Q1的控制端电连接，开关管Q2的输出连接端接地；开关管Q1的输入连接端与电芯电连接，开关管Q1的输出连接端与加热器101电连接。
仍以图3所示的加热器的温度曲线示意图为例，在t2～t3时间段，可以提供大小不同的输出功率，以维持加热器在目标温度；控制器进一步通过使提供给加热器的功率相关的电力参数例如电压的频率保持在一个预定值或者一个合适的范围内，从而控制气溶胶生成装置100产生的噪音分贝值。作为一种可行的实施，控制开关管Q2间隙性动作的开关频率，即可实现保持输出电压的改变频率在合适的范围内。作为优选的方案，上述频率介于0.05Hz～10Hz；或者，介于0.05Hz～5Hz；或者，介于0.05Hz～2Hz；或者，介于0.05Hz～1Hz；或者，介于0.05Hz～0.8Hz；或者，介于0.05Hz～0.5Hz；或者，介于0.1Hz～0.5Hz。
在一种示例中，控制器控制功率源交替性地提供至少两个不同电压给加热器，其中一个电压等于零，即功率源间隙性地提供给加热器。作为一个可行的实施，如图12所示的t2～t3时间段，功率源供给至加热器101的电力信号的电压波形为方波。在该方波中，Vmax为供给至加热器101的电力的最大电压值，供给至加热器101的电力的最小电压值为零。
针对不同开关频率进行噪音测试：
测试数量(Qty)：10；
测试方法：气溶胶生成装置离噪声采集器10MM的距离，全无响测量实验室中进行噪声数据实时采集；插入制品(烟支)并在开机后观察在恒温阶段(t2～t3时间段)噪声的平均值；
测试条件：测量实验室底噪音19dB；
测试设备：A5音频分析仪；
判定标准：环境噪音标准：0dB-30dB定位为极静；30dB-50dB定义为安静；50dB-70dB定义为较静。
噪音测试结果：
Figure PCTCN2022122825-appb-000002
Figure PCTCN2022122825-appb-000003
从以上测试结果可以看出，提供给加热器不同功率的改变频率较低时，可以很好的抑制加热器产生的振动噪音。作为优选方案，在开关管Q2的开关频率介于0.5Hz～10Hz时，虽然可以听到声音，但是测试分贝处于用户可接受的范围(极静范围)；在开关管Q2的开关频率介于0.5Hz以下时，贴近人耳几乎听不到声音，用户体验感最佳。随着开关管Q2的开关频率的降低，测试的分贝值也是相应的降低。在实施中，控制器可以被配置为提供给加热器不同功率的改变频次维持在0.5Hz～10Hz中某一特定值或者在该范围中变动。
需要说明的是，图9至图12的电力信号的频率控制方式，也适用于图2-图8的示例。在一种示例中，通过同时控制流经加热器101的电流变化量和间隙性提供电力信号的频率，控制气溶胶生成装置10产生的噪音分贝值。
