其中，预热工作阶段结束时刻，相当于抽吸工作阶段的开始时刻，气溶 胶产生装置10可以通过振动马达或者视觉显示组件等元器件来进行提醒，提醒使用者气溶胶产生装置10进入抽吸工作阶段，可以进行抽吸动作。
其中，启动加热指令可以是使用者操作输入元件所产生的信号、也可以是依赖传感器的检测信号所得到的，例如通过压力传感器或者电参数传感器等来气溶胶生成制品20插入气溶胶产生装置10的到位触发信号、或者通过气流传感器来检测通过使用者抽吸进行启动的信号等。
其中，控制器102控制功率源101对加热器103进行多次能量供给，均是严格按照预先设定的每一个时间阶段对应的供给能量(又称：设定能量)进行的。这多个时间阶段所对应的供给能量可以预先存储在气溶胶产生装置10内部的存储器中，供控制器102调取。这多个时间阶段所对应的供给能量也可以存储在与气溶胶产生装置10连接的外部设备中，例如云端服务器、充电盒存储器、或者与其联机的气溶胶产生装置10内部的存储器等，控制器102可以在工作过程中从外部存储器或者服务器来进行调取并引用。
其中，设定能量可以是在气溶胶产生装置10的装机设计完成之后，结合具体的气溶胶形成基质的材料等，基于本申请人的大量测试实验所得到的实验值，也可以是经验值。可以理解的是，设定能量可以基于加热模组的保温性能而调整，也可以基于气溶胶形成基质与加热器103之间的热传递速率而调整等。
在一些实施例中，至少两个时间阶段的设定能量不同。例如，在预热工作阶段的前期(又称第一时间阶段，升温阶段)中，加热需求是为了加热器103能快速地达到最高温度，以提升加热器103与气溶胶形成基质之间的热传递速率；而在预热工作阶段的中后期(又称第二时间阶段，保温阶段)，加热需求是维持气溶胶形成基质与加热器103之间的热传递，使气溶胶形成基质能从加热器103继续吸收热量，因此，第一时间阶段所设定能量远远大于第二时间阶段所设定能量，甚至高达8:2或者9:1。例如，在抽吸工作阶段中，为了提升抽吸前期烟雾的输出量，抽吸工作阶段的前期中的至少一个时间阶段的设定能量可以大于抽吸工作阶段的后期中的至少一个时间阶段的设定能量。
在一些实施例中，至少两个时间阶段对应的设定能量相同。例如，在抽吸工作阶段(又称恒温阶段)，加热需求是补充气溶胶形成基质的热量损耗， 以保证气溶胶按照一定的速率生成。由于抽吸动作所导致气溶胶形成基质的热量损耗非常小，因此抽吸工作阶段的多个时间阶段中，可以提供相同的设定能量，以补充气溶胶形成基质的其他固定的热能损耗即可。例如，在预热工作阶段的后期(第二时间阶段，保温阶段)，加热需求是维持气溶胶形成基质与加热器103之间的热传递，使气溶胶形成基质能从加热器103继续吸收热量，因此在保温阶段中，也可以提供相同的设定能量，并且隔一段时间就补充加热器103因其他原因导致的固定的热能损耗，使得加热器103的温度不要大幅下降，就可以维持住气溶胶形成基质与加热器103之间的热传递。
下面以其中一个时间阶段为例，结合图4，详细阐述控制功率源101对加热器103进行当前时间阶段的能量供给的过程(步骤S12)，具体包括：
步骤S121、控制功率源对加热器103启动当前时间阶段的能量供给。
控制器102调取当前时间阶段的设定能量，依照设定能量，控制器102控制电芯101提供功率，以将设定能量供给至加热器103。
其中，控制器102所提供的功率可以是电芯101所能提供的最大实时功率；在此种情况下，随着电芯容量的衰减，电芯101供给至加热器103的能量的持续时长也会随着延长。
其中，控制器102所提供的功率也可以是电芯101经过调压电路之后所输出的稳定功率。具体的气溶胶产生装置10还包括耦接在加热器103与电芯101之间的调压电路；调压电路包括升压电路和/或降压电路。例如：如图5所示的BUCK-BOOST变换电路。可以理解的，调压电路并不限于BUCK-BOOST变换电路，还可以为BOOST变换电路、BUCK变换电路、CUK变换电路、ZETA变换电路、SEPIC变换电路中的至少一种。
其中，控制器102提供功率的过程可以为不间断地连续输出，这样可以更好地补充加热器103以及气溶胶形成基质的热量损耗。以一个时间阶段为例，控制器102连续输出功率的时间仅占当前时间阶段的一部分，本文把此部分称为能量供给时间。在一些实施例中，能量供给时间是变化的，控制器102根据当前时间阶段的设定能量以及实时的输出功率来控制能量供给，而不限定能量供给时间。在一些实施例中，在功率源102的输出功率稳定的情况下，能量供给时间可以是预先设定的。因此，控制器102可以根据当前时间阶段的设定能量以及预设的能量供给时间，来确定所输出的功率。在一些实 施例中，例如，在能量供给时间内，加热器103在能量供给下，一般情况下，其温度开始上升，其温度上升的速率是由设定能量、实际的功率输出等所决定的。
在抽吸工作阶段中，当前时间阶段与使用者的抽吸动作同步发生时，由于抽吸工作阶段的多个时间阶段的频率设置，使得一次抽吸动作的时间内(约5s)至少存在一个时间阶段的能量供给，由抽吸动作所带走热量极小，仅为使得加热器103的温度变化的过程中出现一些抖动的情况，加热器103及气溶胶形成基质的热量依然能及时得到补充，因此加热器103的温度依然可以保持在一个温度范围内波动，而不会产生大幅度的掉温。
需要强调的一点，本方案中所提供的多个时间阶段的能量供给，是为了满足各个阶段气溶胶形成基质的热量需求，仅需要低频地进行能量供给即可。因此，每个时间阶段的能量供给时间≥500ms(毫秒)，优选1s以上或者频率≤2Hz；而常规PWM控制通常为了输出精准的功率，其输出频率约为100Hz，属于高频输出，与本方案的用意并不相同。
步骤S122、确定当前时间阶段的已供给能量。
控制器102在输出功率的当时，同步统计已经输出的已供给能量。
在一些实施例中，可以通过检测电路检测加热器103的电压、电流和/或电阻等电参数，以及供给的持续时长(能量供应时间)，再根据能量Q＝P*t＝U^2/R*t＝I^2*R*t＝U*I*t的公式，可以计算得到加热器103已供给能量的。
在一些实施例中，在加热器103加热的过程中，部分电参数保持恒定不变的情况下，例如，在加热器103的恒定电压供应的情况下，或者恒流供应的情况下，或者加热器103的电阻保持恒定等情况下，可以仅通过只监控部分的电参数或者持续供应的时间，来间接地表征已供给能量。
步骤S123、判断当前时间阶段的已供给能量是否达到当前时间阶段所对应的设定能量。
控制器102通过比较已供给能量是否达到设定能量，若没有达到，则继续进行能量供给，若达到，则进入步骤S124。
步骤S124、若已供给能量达到当前时间阶段所对应的设定能量，则控制所述功率源停止当前时间阶段的能量供给。
控制器102在停止对加热器103的能量供给，并持续一段的时间，本文将称之为自然冷却时间。在一些实施例中，自然冷却时间是预先设定好的，其与加热模组保温性能、或者加热器103与气溶胶形成基质之间的热传递需求等因素相关。因此，控制器102在完成当前时间阶段的能量供给之后，在预设的自然冷却时间内，停止给加热器103的能量供给，并通过计时来确定自然冷却时间是否达到截止时间。在一些实施例中，自然冷却时间也可以不直接设定，例如，通过检测加热器103的实时温度，来确定是否结束自然冷却时间，此时的自然冷却时间在多个时间阶段之间是可以变化的。
在自然冷却时间内，由于加热器103没有能量供给，加热器103的温度自然开始下降，这部分的温度损失是由于加热器103与外界/气溶胶形成基质的热量损耗，在抽吸工作阶段中还可能叠加上抽吸动作所带来的热量损失。
随着自然冷却时间的结束，当前时间阶段也正式结束。此时气溶胶产生装置10的总工作时长(或者满足预设的抽吸口数)已经到达预先设定阈值，或者控制器102接收到结束加热的指令，则结束气溶胶产生装置10的工作，不再进入下一时间阶段。在一些实施例中，如图4所示，在当前时间阶段结束之后，则需要跳转到下一个时间阶段中(步骤S12’)，并且重复执行上述的步骤S121-S124。
图6和图7具体示出当前时间阶段与下一个时间阶段之间的跳转过程。
在一些实施例中，如图6，控制器102在结束当前时间阶段的能量供给之后，进入当前时间阶段的自然冷却时间，并进行计时，当自然冷却时间到达预设的截止时间，则结束当前时间阶段，并且进入下一个时间阶段。此时，控制器102可以直接按照每一个时间阶段的设定能量和自然冷却时间，来进行多个时间阶段的能量供给及跳转，此种方式无论在当前时间阶段的启动还是停止能量供给，均无需关注加热器103的实时温度，仅严格依照每个时间阶段的设定能量以及自然冷却时间等参数的设置来执行即可，可以排除加热器103温度的不良干扰，而是真正地从气溶胶形成基质生成气溶胶所需要吸收的热量出发来控制。
在另一实施例中，如图7所示，气溶胶产生装置10内还包括用于检测加热器103的实时温度的温度传感器，控制器102在结束当前时间阶段的能量供给之后，进入当前时间阶段的自然冷却时间，并在自然冷却时间内同步检 测加热器103的实时温度，当实时温度满足预设的低温阈值(例如图10A-10B，T3)，则结束当前时间阶段，并进入且启动下一个时间阶段的能量供给。此种方式，仅需在何时启动一个时间阶段来提供能量供给予以加热器103，需要参考加热器103的实时温度，而在一个时间阶段内的能量供给，例如何时停止一个时间阶段内的能量供给，依然是严格依照每个时间阶段的设定能量来执行。也同样可以排除加热器103实时温度的差异对于控温的影响，而是从气溶胶形成基质生成气溶胶所需要吸收的热量出发来控制。
图8A-8D示出了预热工作阶段的多种形态的供电电压示意图。预热工作阶段t0～t2包含多个时间阶段(t0-t12)、(t12-t14)、(t14-t16)、......。
控制器102接收到启动加热指令之后，正式进入预热工作阶段，启动第一时间阶段(t0-t12)的能量供给，控制器102此时提供最大输出电压U0给予加热器103，并持续一定的时间(能量供给时间，t0-t11)，控制器102同步计算已供给能量，当已供给能量达到第一时间阶段的设置值Q1，控制器102则控制功率源101停止输出功率，并持续一定的时间(自然冷却时间，t11-t12)，当自然冷却时间t11-t12达到第一时间阶段的设定时长，则结束第一时间阶段，进入第二时间阶段(t12-t14)并启动功率输出。
在一些实施例中，在第一时间阶段中的加热器103的输入电压可以保持不变。优选的，此时的第一时间阶段的自然冷却时间不超过3s。
在一些实施例中，控制器102提供给加热器103的功率(输出电压)，在第一时间阶段内的后期至少降低一次，以使在第一时间阶段内提供给加热器103大功率持续的能量供给的同时，进一步通过小功率输出来维持气溶胶形成基质20与加热器103之间的热传递，也不会引起加热器103的温度过冲，从而提升使用者的抽吸体验。此时，如图10A-10B所示，加热器103的温度从初始温度快速地升到最高温度，并呈抛物线的形式略微回落。
其中，第一时间阶段后期的功率调整可以采用多种形式来实现。例如，如图8A，加热器103的输入电压随时间变化呈多次阶梯性下降，其中每一个阶梯电压的持续时长/降低幅度可以根据实际需求而调整。如图8B，加热器103的输入电压随时间变化呈一次的阶梯性下降。如图8C，加热器103的输入电压随时间变化呈线性下降，其中，可以以恒斜率的线性下降，或者以变化斜率地线性下降。如图8D，加热器103的输入电压随时间变化呈波浪变化， 或者说加热器103的输入电压有升有降。
其中，第一时间阶段后期功率下降的持续时长(t1-t11)介于2～3s(秒)。
在第二时间阶段(t12-t14)中，控制器102输出电压U1(U1＜U0)给予加热器103，并持续一定的时间(能量供给时间，t12-t13)，此时加热器103的温度小幅度上升；当已输出的已供给能量达到第二时间阶段的设置值Q2(Q2＜Q1)，控制器102则停止输出功率，并再持续一定的时间(自然冷却时间，t13-t14)，此时加热器103的温度小幅度回落。如图10A-10B所示，在第二时间阶段(t12-t2)时，加热器103的温度成波动变化。
其中，第二时间阶段的操作步骤可以被重复多次执行，例如3-5次。多个第二时间阶段之间的设定能量或者自然冷却时间的设定可以一样，也可以有所不同。此时，如果多个第二时间阶段的设定能量及其自然冷却时间设置相同，则加热器103的温度呈现出在一定温度范围内上下波动的表现形式。
其中，多个第二时间阶段的总持续时长介于5-8s(秒)，气溶胶形成基质可以利用这段时间充分吸收热量，却又不会导致气溶胶过度生成。
在预热工作阶段中，第一时间阶段的设定能量占整个预热工作阶段的设定能量的总和的80％以上，这样有利于气溶胶形成基质快速地且产生充足的令人期待的气溶胶。
当第二时间阶段结束时，预热工作阶段(t0-t2)则也正式结束。此时，进入抽吸工作阶段(t2-t3)，且控制器102会向使用者发送抽吸工作阶段开始的提醒信息。
图9A-9B示出了抽吸工作阶段的多种形态的供电电压示意图。
在抽吸工作阶段中，同样存在多个时间阶段(此处称为第三时间阶段)t21、…、t2n、……、t2k，其中，k介于6～20。第三时间阶段的控制步骤与第二时间阶段的控制步骤相同，但是设定能量和自然冷却时间的设定可能有所不同。其中，第三时间阶段的总时长至少2s(秒)，或者介于2.5-5s(秒)，或者介于3-4s(秒)，具体根据不同加热模组的升温特性和保温特性决定。
如图9A-9C，抽吸工作阶段(t2-t3)开始，启动第一个第三时间阶段(t21)，控制器102输出电压U21给予加热器103，并在能量供给时间(t21-1)内持续供给，控制器102同步计算已供给能量，当已供给能量满足设定能量Q21时，则控制器102停止输出功率，并持续自然冷却时间(t21-2)；当停止输 出功率的时长满足预定的自然冷却时间，或者，当此时加热器103的实时温度达到温度阈值T3，则第三时间阶段(t21)结束，进入并启动第二个第三时间阶段(t22)的能量供给。
其中，在第一个第三时间阶段中，加热器103的温度开始小幅度上升，直至达到温度阈值T2，在自然冷却时间内，加热器103的温度小幅度回落，直至到达温度阈值T3。
在一些实施例中，利用加热器103的实时温度来启动能量供给的情况，若存在抽吸动作，在第三时间阶段的能量供给时间，加热器103的温度依然上升，但可能会受到抽吸动作的影响而导致温度上升速率稍缓一些；在第三时间阶段的自然冷却时间，加热器103的温度依然下降，但可能会受到抽吸动作的影响而导致温度下降速率增大。但是此时，一识别到加热器103的实时温度达到温度阈值T3时，则马上启动下一个第三时间阶段的能量供给，此时，加热器103的温度会马上回升。在这种情况中，自然冷却时间提前结束，而多个第三时间阶段之间的能量供给更加紧凑，通过增加第三时间阶段的次数则可以解决抽吸动作所带来的影响，而加热器103的温度依然保持在温度范围(T2-T3)之间波动。
在一些实施例中，在完全不依赖加热器103的实时温度进行控制情况下，若存在抽吸动作，在第三时间阶段的能量供给时间，加热器103的温度依然上升，但可能会受到抽吸动作的影响而导致温度上升速率稍缓一些；在第三时间阶段的自然冷却时间，加热器103的温度依然下降，但可能会受到抽吸动作的影响而导致温度下降速率增大。由于一口抽吸动作的持续时间内存在至少一个第三时间阶段的能量供给，抽吸动作所带走的能量损耗小于至少一个的第三时间阶段的总能量供给，因此也不会引起加热器103的温度产生大幅度的下降，加热器103的温度也依然可以保持在一个小温度范围(T2-T3)内波动。其中，加热器103的波动幅度可能不一致。
其中，第三时间阶段的操作步骤可以在抽吸工作阶段中重复多次执行，而多个第三时间阶段之间的跳转可以参照t21与t22之间的跳转。
图9A-9C示出多个第三时间阶段之间的能量供给与自然冷却时间的多种情况。
如图9A，通过将多个第三时间阶段之间的设定能量设置为相同，能量供 给时间设置为不同，自然冷却时间相同，此时加热器103在温度区间(T2-T3)的温度波动为可变化频率的表现形态。其中，自然冷却时间与加热模组的保温性能相关。
如图9B，通过将多个第三时间阶段之间的设定能量设置为相同的，能量供给时间设置为相同，自然冷却时间也相同，此时加热器103在温度区间(T2-T3)的温度波动为恒定频率。其中，自然冷却时间与加热模组的保温性能相关。
如图9C，通过将多个第三时间阶段之间的设定能量设置为不同，例如前面的设定能量多，后面的设定能量相对较少，能量供给时间设置为相同，自然冷却时间也相同，此时加热103在温度区间(T2-T3)的温度波动为可变化频率的表现形态，且先小后大，从而可以在抽吸工作阶段的前期产生足够的气溶胶。其中，自然冷却时间与加热模组的保温性能相关。
在一些实施例中，以电阻厚膜发热的周向形态的加热器103为例，由于电阻厚膜加热器具有升温快、保温性较弱的特性，控制器102在接收到启动加热的指令之后，进入预热工作阶段，首先根据第一时间阶段的设定能量，可以在第一时间阶段中输出功率约为25W，能量供给时间约为15s，此时加热器103的温度从初始温度上升到380℃；然后停止能量经历第一时间阶段的自然冷却时间(约3s)之后，依次启动3-5个第二时间阶段，每个第二时间阶段的输出功率约为6W，能量供给时间约为1s(可根据实时功率变化)，自然冷却时间约为3s；在经历了多个第二时间阶段的能量供给之后，此时加热器103的温度约在230℃；随后进入了抽吸工作阶段，并重复启动6-20次第三时间阶段，每个第三时间阶段的输出功率约为5W，能量供给时间约为1-2s(可根据实时功率变化)，自然冷却时间约为3s，使得加热器103的温度在230℃的上下呈波浪形波动，直至抽吸工作阶段结束。
在一些实施例中，以红外发热的周向形态的加热器103为例，由于红外加热器具有升温慢、保温性良好的特性，控制器102在接收到启动加热的指令之后，进入预热工作阶段，首先根据第一时间阶段的设定能量，可以在第一时间阶段中输出功率约为35W，能量供给时间约为20s，此时加热器103的温度从初始温度上升到280℃；然后停止能量经历第一时间阶段的自然冷却时间(约3s)之后，依次启动3-5个第二时间阶段，每个第二时间阶段的输 出功率约为6W，能量供给时间约为1s(可根据实时功率变化)，自然冷却时间约为4-8s不等；在经历了多个第二时间阶段的能量供给之后，此时加热器103的温度大约在240℃以上；随后进入了抽吸工作阶段，并重复启动6-20次第三时间阶段，每个第三时间阶段的输出功率约为5W，能量供给时间约为5s(可根据实时功率变化)，自然冷却时间约为4s，使得加热器103的温度在240℃上下呈波浪形波动，直至抽吸工作阶段结束。
