背景技术
随着雾化技术的发展，出现了电子烟技术，电子烟又名虚拟香烟、电子雾化装置，用于作为替代香烟的用品，也被用于戒烟。电子烟是利用发热元件对烟油进行雾化后供用户抽吸。
目前的电子烟一般在启动工作后，控制发热元件的温度迅速升高，使得能够快速达到雾化温度，开始雾化烟油，并在开始雾化后采用恒功率加热，使发热元件能够持续保持相对稳定的温度进行加热，使得雾化产生的气溶胶量比较均匀。
然而，目前的加热方式，在持续加热后发热元件上能够被加热的烟油会逐渐减少，同时再从储液腔内吸取烟油继续进行加热，但在恒功率加热的过程中，发热元件雾化面的气膜的蒸汽压较大，会对微孔内和微孔附近的烟油产生挤出效应，使得雾化面的烟油无法及时补充，继续持续可能加热会使雾化面发生过热的问题，甚至出现局部干烧的现象。进而造成雾化组件的损坏，在发热元件上产生较多烟垢、产生焦味和其他有害物质，影响用户的正常使用。

正如背景技术所述，现有技术中的气溶胶雾化装置存在容易产生烟垢和焦味的问题，经发明人研究发现，出现这种问题的原因在于，由于烟油在被加热雾化形成气溶胶时需要由一定的过热度，而烟油中存在多种成分，包括丙二醇、丙三醇及香精香料等，这些成分的混合物为非共沸物质，其中的某些成分的沸点远低于过热度，然而恒功率的加热模式使 得烟油中的一些成分长期处于过热条件下，导致烟油中低沸点的物质在雾化烟油的过程中发生焦化反应，产生碳化颗粒物，在气溶胶雾化装置的持续工作下，碳化颗粒物不断累积和恶化，在雾化面上积累的碳化颗粒物长期经高温加热烘烤则会产生焦味。
基于以上原因，本申请提供了一种能够减少产生烟垢和焦味的加热控制方案，同时还能保证雾化量，不影响用户的体验。
在其中一个实施例中，如图1所示，提供了一种雾化加热控制方法，应用于气溶胶产生装置，气溶胶产生装置包括：加热器，其包括被配置用于加热气溶胶形成基质的至少一个发热元件；以及；
用于向发热元件提供电力的电源；
所述方法包括：
控制向发热元件提供的电力，从而使得，执行以下步骤：
步骤S100，在第一阶段，控制发热元件以预设的第一功率加热至预设的第一温度范围，以使发热元件开始雾化气溶胶形成基质。
第一阶段可以是气溶胶产生装置每次执行雾化加热工作过程中的第一个加热阶段，也可以是气溶胶产生装置每次执行雾化加热工作过程中其中一个加热周期的第一个加热阶段。第一功率需要采用较大功率，发热元件以第一功率进行加热，能够快速达到雾化温度开始雾化，保证气溶胶产生装置开始产生气溶胶的速度。第一温度范围为气溶胶形成基质能够进行雾化的温度范围，在其中一个实施例中，第一温度范围的下限温度大于气溶胶形式基质的雾化临界温度，雾化临界温度是指气溶胶形式基质能够开始雾化的临界温度。
步骤S200，在第二阶段，控制发热元件的加热功率波动变化，以使发热元件的温度在预设的第二温度范围内波动变化。
第二阶段可以是气溶胶产生装置每次执行雾化加热工作过程中的第二个加热阶段，也可以是气溶胶产生装置每次执行雾化加热工作过程中其中一个加热周期的第二个加热阶段。此阶段控制发热元件的加热功率高低波动变化，但需要使发热元件的温度维持在第二温度范围内进行波动变化，即通过交替采用高低功率，使发热元件的温度在第二温度范围内上下波动，在高温加热一段时间后降低加热温度，低温加热一段时间后再次进行高温加热。发热元件在低功率加热时，气膜内的蒸汽压能够降低，使陶瓷微孔中的气溶胶形成基质在毛细作用力的作用下克服蒸汽压作用力，向发热元件的雾化面补充烟油，在下一个时间段进入高功率加热时有充足的气溶胶形成基质能够进行加热，避免局部干烧，减少持续高温产生烟垢，避免产生焦味，同时由于温度保持在一定范围内波动，与间断加热不同， 这种控温方式利用了发热体具备热惯性的特点，高低功率切换时温度不会急剧下降至无法雾化的温度，保证烟雾量。如图2所示为在一个实施例中采用恒功率加热及采用本申请的雾化温度控制方法加热的功率变化图。如图3所示为在一个实施例中，采用恒功率加热(曲线b)及采用本申请的雾化温度控制方法加热(曲线a)的温度变化图，可以看到温度超过300℃的时间减少了近一半。
在其中一个实施例中，若气溶胶形成基质为烟油，由于烟油的成分复杂，不同物质的沸点不同，例如一些常见的烟油中主要物质的沸点一般在189℃～300℃之间，若持续高温加热会使得低沸点物质发生高温裂解产生有害物质，本申请通过在第二阶段主动控温，使得发热元件雾化面的温度在一个温度范围区间内波动变化，既可以使烟油中各成分物质分别进行沸腾雾化，又降低了烟油高温裂解的反应程度，减少有害物质的产生。
如图4所示，烟油过热沸腾会形成气泡，气泡产生的蒸汽压大小由发热元件雾化面的温度决定。在低功率加热时，烟油的过热度较低还无法形成大气泡，此时气泡的蒸汽压力较低，发热元件导液孔内的烟油在毛细作用力下可以往雾化面进行供液；而在高功率加热时，由于雾化面温度高，烟油过热产生大气泡，此时气泡的蒸汽压大于毛细作用力，使导液孔烟油被往储油仓方向挤压。通过采用高、低功率交替加热，能够使得烟油不断的运动，使得碳化颗粒物难以停留附着在发热元件的雾化面，从而减少了烟垢的积累。
上述雾化加热控制方法，通过控制发热元件以第一功率先加热至预设的第一温度范围，开始雾化气溶胶形成基质，随后在第二阶段，控制发热元件的加热功率波动变化，以使发热元件的温度在第二温度范围内波动变化，使得发热元件能够有降温的时间，而非持续保持较高温度进行加热，降低发热元件气膜的蒸汽压，使发热元件能够充分补充气溶胶形成基质，避免发生局部干烧，减少碳化颗粒物的产生。
在其中一个实施例中，如图5所示，雾化加热控制方法还包括：
步骤S300，在第三阶段，调整发热元件的加热功率，以使发热元件的温度保持在预设的第三温度范围内；第三温度范围的最大温度差小于第二温度范围的最大温度差。
最大温度差是指温度范围的上限与下限之差，第三温度范围的最大温度差为第三温度范围的上限温度与下限温度之差；第二温度范围的最大温度差为第二温度范围的上限温度与下限温度之差。
第三阶段可以是气溶胶产生装置每次执行雾化加热工作过程中的第三个加热阶段，也可以是气溶胶产生装置每次执行雾化加热工作过程中其中一个加热周期的第三个加热阶段。在第三阶段，控制发热元件温度在一个较小的温度范围内波动，进一步保证气溶胶产 生装置的产生烟雾的量。在第三阶段，发热元件的加热功率可以是恒定功率，也可以是波动变化的功率。
在其中一个实施例中，在第二阶段，发热元件相邻的两次波动变化得到的加热功率之差的绝对值大于预设的第一功率差。
在第二阶段，为了保证发热元件能够充分且及时地补充烟油，需要保证发热元件温度波动的温差足够大，使得温度从较低的温度上升到较高的温度这一过程有充足的时间，同时还能使各种成分都能够充分进行沸腾。因此需要控制发热元件每次交替变化高低功率之间的差值足够大，可以通过预设的第一功率差进行功率调控的控制。每次交替变化的加热功率中高功率可以是固定的功率值，也可以变化的功率值；低功率可以是固定的功率值，也可以是变化的功率值，只需满足相邻两次波动变化的加热功率之差的绝对值大于第一功率差。例如在t1时间采用第一高功率，t2时间采用第一低功率，t3时间采用第二高功率，t1时间、t2时间和t3时间为连续的三个时间段，其中，第一高功率与第一低功率之差的绝对值，需要大于第一功率差；第一低功率与第二高功率之差的绝对值也需要大于第一功率差。
在其中一个实施例中，在第三阶段，发热元件的加热功率波动变化，且发热元件相邻的两次波动变化得到的加热功率之差的绝对值大于预设的第二功率差；所述第二功率差小于所述第一功率差。
在第三阶段中，为了保证烟雾量的同时，避免长时间维持过热使得产生烟垢或是发热元件无法及时补充烟油，控制发热元件的加热功率以相对第二阶段较低的波动差进行波动变化，通过预设的第二功率差来对发热元件的加热功率波动进行控制，保证发热元件温度有一定的高低变化，但温差相对于第二阶段较小。
在其中一个实施例中，如图6所示，所述在第二阶段，调整发热元件的加热功率，以使所述发热元件的温度在预设的第二温度范围内波动变化的步骤包括：
步骤S210，在持续以第一功率加热预设的第一时间后，控制发热元件将加热功率降低至预设的第二功率进行加热。
持续以第一功率加热预设的第一时间后，即第一阶段后，控制发热元件将加热功率降低至预设的第二功率进行加热。由于第一阶段需要快速达到能够雾化的温度，因此第一功率的值较高，在第一阶段结束后，降低加热功率，采用相比第一功率要低的第二功率进行加热，进而降低发热元件的温度，为发热元件提供补充烟油的时间，为下一个时间段的高功率加热提供充足的气溶胶形成基质。
步骤S220，在持续以第二功率加热预设的第二时间后，控制发热元件将加热功率增大至预设的第三功率进行加热。
以第二功率加热预设的第二时间后，为了实现在第二阶段发热元件的加热功率的波动变化，将加热功率增大至第三功率，第三功率大于第二功率，使得发热元件进入高温加热状态，充分雾化气溶胶形成基质。
根据不同发热元件的升温特性，可以将第二阶段分为若干个时间段，控制加热功率波动变化，交替使用高低功率进行加热。例如第二阶段分为N个时间段，包括n1～nN时间段，在n1时间段采用第一低功率，在n2时间段采用第一高功率，在n3时间段采用第二低功率……在n(N-1)时间段采用第n低功率，在nN时间段采用第n高功率。n1～nN时间段内每个时间段可以是相等的，也可以是不相等的，或是部分相等部分不相等。n和N均为自然数。通过交替使用高低功率进行加热，能够缩短高温加热的时间，减少发热元件过热时间，在保证烟雾量的同时，减少烟垢的产生，避免产生焦味，避免发生局部干烧。
在其中一个实施例中，如图7所示，所述在第二阶段，调整发热元件的加热功率，以使发热元件的温度在预设的第二温度范围内波动变化的步骤包括：
步骤S230，周期性地调整发热元件的加热功率，以使发热元件的温度在第二温度范围内周期性地波动变化。
周期性地调整发热元件的加热功率，即将第二阶段等分为N个时间段，通过在N个时间段内交替控制发热元件的高功率和低功率进行加热，使发热元件的温度在第二温度范围内周期性的波动变化。例如N个时间段包括n1～nN，在n1时间段采用第一低功率，在n2时间段采用第一高功率，在n3时间段采用第二低功率……在n(N-1)时间段采用第n低功率，在nN时间段采用第n高功率，n1～nN时间段内每个时间段均相等，使得发热元件的温度周期性地波动变化。气溶胶形成基质过热度呈周期性变化，能够促使沸腾气泡间隙性地增大缩小，从而对发热元件微孔周围的气溶胶形成基质形成挤压效应，使得碳化颗粒物不容易附着在发热元件表面，或是堵塞在发热元件的导液孔中。
