一同参考图8，气溶胶产生装置10中微波控制方法在一些实施例中可包括下述步骤：
S1、微波控制电路114控制微波生成电路112生成微波，使微波发射天线113在预设微波频率范围内扫频发射微波，微波用于加热雾化腔体12中的气溶胶生成制品20。具体地，微波控制电路114确定预设微波频率，控制微波生成电路112按预设微波频率生成微波。微波发射天线113在预设微波频率范围内扫频发射微波，至少部分微波聚集在雾化腔体12以加热气溶胶生成制品20。需要说明的是，微波发射天线113在预设微波频率范围内扫频发射微波需要通过微波控制电路114实现，微波控制电路114在预设微波频率范围扫频确定预设微波频率，例如从预设微波频率范围的最小频率逐渐增大频率至预设微波频率范围的最大频率，或从预设微波频率范围的最小频率按照预设频率间隔逐渐增大频率至预设微波频率范围的最大频率，或从预设微波频率范围的最大频率逐渐减小频率至预设微波频率范围的最小频率，或从预设微波频率范围的最大频率按照预设频率间隔逐渐减小频率至预设微波频率范围的最小频率。又例如，预设微波频率范围内包括至少两个预设微波频率点，按照预设顺序依次发送每个预设微波频率点至微波生成电路。
S2、反馈采集电路115采集微波对应的反馈信号，将反馈信号发送至微波控制电路114。具体地，反馈采集电路115在微波发射天线113发射微波后采集微波发射天线113发射的预设微波频率微波对应的反馈信号，将反馈信号传输至微波控制电路114。
S3、扫频发射微波结束后，微波控制电路114根据反馈信号选择微波发射频率。具体地，扫频发射微波结束后，微波控制电路114根据反馈信号选择微波发射频率维持或修正预设微波频率，即选择合适的微波发射频率以使雾化腔中的气溶胶生成制品20达到最佳雾化状态。作为选择，选择气溶胶生成制品20吸收最多的微波发射频率作为最优微波发射频率，气溶胶产生装置10以该最优微波发射频率发射微波，直至下一次微波扫频。
在一些实施例中，使用微波直接加热气溶胶生成制品20，且通过扫频调整微波发射频率，加热效率高，延长设备使用寿命。
在一些实施例的微波控制方法中，步骤S3中微波控制电路114根据反馈信号选择微波发射频率包括：微波控制电路114根据反馈信号选择微波发射频率和微波发射功率，同时调整微波发射频率和微波发射功率，使雾化腔体12中的气溶胶生成制品20达到最佳雾化状态。
在一些实施例的微波控制方法中，步骤S2中反馈信号为反向微波功率。微波发射后，并非所有微波都会被气溶胶生成制品20吸收，部分未被吸收的微波被反向微波功率检测，得到反向微波功率。对应的，步骤S3中微波控制电路114根据反馈信号选择微波发射频率包括：微波控制电路114选择反向微波功率最小值所对应的微波发射频率。
在一些实施例的微波控制方法中，气溶胶产生装置10在制造过程中会存在误差，该误差可能导致出厂时预设的微波发射频率并非最优微波发射频率，因此需要对预设微波发射频率进行校准。在步骤S1之前还包括：S101、微波控制电路114接收到微波频率选择指令，微波频率选择指令可由实体按键或虚拟按键等产生。当然，该步骤可在出厂时完成，也可在用户首次使用时完成。
在一些实施例的微波控制方法中，因每种气溶胶生成制品20对应的微波频率不同，即每种气溶胶生成制品20共振发热的微波频率不同，为达到最好的加热效果，在步骤S1之前还包括：S102、微波控制电路114接收到气溶胶生成制品安装完毕指令，即在用户新安装或更换气溶胶生成制品20后，产生气溶胶生成制品20安装完毕指令。
在一些实施例的微波控制方法中，随着气溶胶生成制品20的消耗，气溶胶生成制品20需要加热的位置不断变化，为使微波能准确加气溶胶生成制品20，在步骤S1之前还包括：S103、微波控制电路114接收到抽吸指令，用户每次抽吸时产生抽吸指令。

在一些实施例中，为了防止微波经由开口120泄漏，滤嘴段24可采用具有屏蔽作用的材料制成。具体地，可采用泡沫金属、导电泡棉、碳材料、聚合物复合材料、金属导电纤维与醋酸纤维丝束的混合织物、以金属导电纤维为芯材与外层包覆普通纤维的混合纤维丝束中的至少一种材料制成。该滤嘴段24能够吸收、反射少量的微波返回到气溶胶生成部件22中，具有一个增强加热作用。该具有微波屏蔽的滤嘴段能够防止气溶胶生成制品20在较强微波场区域A时的高温打火现象，也能促进微波反射的增强作用，可以有效屏蔽微波，提高抽吸时的安全性。

可选地，上述气溶胶生成部件22中的烟草221还包括香料及无机填料中的至少一种。在烟草221中添加香料，可以丰富气溶胶生成部件22的味道。在烟草221中添加的无机填料对基础烟草有一定的支撑作用，便于塑形。当然，香料及无机填料的种类和用量可以根据实际需求进行选择和调整。
气溶胶形成剂222用于形成气溶胶。可选地，气溶胶形成剂中含有丙二醇。当然，气溶胶形成剂222在一定程度上粘附于烟草上。进一步地，气溶胶形成剂222中含有微波吸收性能良好的物质。微波吸收良好的物质可以通过直接吸收微波而迅速气化，从而产生烟雾，实现加热不燃烧。具体地，微波吸收性能良好的物质对特定波长微波的损耗角正切大于0.1。更进一步地，气溶胶形成剂222中微波吸收性能良好的物质的质量百分数为1%~50%。
在含有微波吸收性能良好的物质的气溶胶形成剂222中，烟雾主要通过微波吸收性良好的物质的沸腾/蒸发产生，最高温度为微波吸收性良好的物质的沸点，因此可实现自控温，所以不需要控温部件。当然，上述气溶胶生成部件22吸收微波的能力随着微波吸收性能良好的物质的量的减少而减弱，在微波吸收性能良好的物质释放完全后，上述气溶胶生成部件22吸收微波的能力大为降低，不能继续有效吸收微波能量从而升温，因此不易出现烧焦等不利现象。并且经过多次试验表明，上述气溶胶生成部件22的抽吸寿命有一阈值，在此阈值前，气溶胶生成部件22的口感不错，有效成分充分释放，但超过该阈值后，整个气溶胶生成部件22寿命到期，有效成分已释放完毕，口感欠佳。因此，可以通过微波吸收性能良好的物质（例如丙二醇）的添加量以及抽吸口数来精确控制上述气溶胶生成部件22的抽吸寿命。此外。微波加热具备均匀性以及温度梯度为由内向外的特点，不存在如中心加热装置那样的加热烟草不充分的问题。
可选地，气溶胶形成剂222中含有丙二醇及丙三醇中的至少一种。进一步地，气溶胶形成剂222中含有丙二醇，且丙二醇的质量百分含量为1%~50%。在一个可选地具体示例中，气溶胶形成剂222中的丙二醇的质量百分含量为2%、5%、10%、15%、20%、35%或45%。进一步地，气溶胶形成剂222中的丙二醇的质量百分含量为5%~15%。
在一些实施例中，气溶胶形成剂222中还含有烟碱类化合物。通过添加烟碱类化合物可以该善由于烟叶质量较差所引起的气溶胶生成部件22的口味较差的问题。当然通过添加烟碱类化合物也可以改善由于烟叶批次不同而引起的气溶胶生成部件22的口味不一致的问题。具体地，烟碱类化合物选自尼古丁及尼古丁盐中的至少一种。
进一步地，气溶胶形成剂222中烟碱类化合物的质量百分含量为0.1%~33%。在一个可选地具体示例中，气溶胶形成剂中烟碱类化合物的质量百分含量为0.1%、2%、8%、10%、15%、20%、25%或33%。在一些实施例中，气溶胶形成剂222还可以含有非烟草调味剂。可选地，非烟草调味剂选自醇类调味剂（例如薄荷醇）和醛类调味剂（例如甜瓜醛）中的至少一种。在其他一些实施例中，非烟草调味剂不限于上述，还可以其他可以食用的非烟草调味剂。
在一些实施例中，功能粒子的表面粗糙。将功能粒子223的表面粗糙化，可以防止暴沸，利于充分雾化烟草221和气溶胶形成剂222。如图19所示，在一个可选地具体示例中，功能粒子223包括吸波材料2231以及形成于该吸波材料2231外表面的红外辐射层2232。在一些实施例中，吸波材料2231的介电损耗角正切或磁滞损耗角正切大于0.1。吸波材料选自碳化硅、氧化锌、碳粉、三氧化二铁及四氧化三铁中的至少一种。在一些实施例中，红外辐射层2232的材料选自堇青石、钙钛矿型（AB2O4，如NiCr2O4，A为La、Sr、Ca、Mg、Bi、N中的一种或多种，B为Al、Ni、Fe、Co、Mn、Mo、Cr中的一种或多种）材料中的至少一种。
在一些实施例中，功能粒子为颗粒状，功能粒子的粒径不超过100μm。可选地，功能粒子的粒径为2.5μm、10μm、15μm、20μm、30μm、40μm、50μm、60μm、70μm、80μm 或100μm。进一步地，功能粒子的粒径为2.5μm~100μm。更进一步地，功能粒子的粒径为10μm~60μm。
可以理解的是，其他一些实施方式中，功能粒子223的形状不限于颗粒状，可以是其他形状。例如，丝状等。
在一些实施例中，功能粒子223具备反射、吸收微波、释放红外辐射的能力，可以起到如下作用：（1）使得气溶胶生成部件22中微波吸收性能良好物质（例如丙二醇、丙三醇等）能接收到更多的微波，从而使得微波吸收性能良好物质能够吸收更多的微波；（2）功能粒子223吸收微波能量升温，热量通过热传导加热附近烟草221和气溶胶形成剂222；（3）功能粒子223升温后，通过较强的红外辐射传递能量给烟草221和气溶胶形成剂222。
在一些实施例中，上述气溶胶生成部件22为片状、球状或椭球状。当然，在其他实施例中，上述气溶胶生成部件22的形状无特别限定，还可以是其他可行的形状。
在一些实施例中，以质量份数计，在上述气溶胶生成部件22中，烟草的份数为40份~98份，气溶胶形成剂的份数为1份~55 ，功能粒子的份数为1份~55份。
在一些实施例中，以质量份数计，在上述气溶胶生成部件22中，烟草的份数为40份~90份，气溶胶形成剂的份数为5份~55份，功能粒子的份数为5份~55份。
在一些实施例中，以质量份数计，在上述气溶胶生成部件22中，烟草的份数为40份~90份，气溶胶形成剂的份数为5份~55份，功能粒子的份数为15份~45份。
在一些实施例中，以质量份数计，在上述气溶胶生成部件22中，烟草的份数为60份~90份，气溶胶形成剂的份数为10份~55份，功能粒子的份数为10份~40份。
在一些实施例中，以质量份数计，在上述气溶胶生成部件22中，烟草的份数为60份~70份，气溶胶形成剂的份数为10份~25份，功能粒子的份数为15份~25份。
上述气溶胶生成部件22至少具有以下优点：
（1）上述气溶胶生成部件22包括烟草221、气溶胶形成剂222和功能粒子223，上述气溶胶生成部件22可以利用915MHz~30GHz的微波而快速生成气溶胶。在很短的时间内（例如，1秒）内即可产生气溶胶，一定时间内（例如，4秒）时所产生的气溶胶的烟雾量远大于传统加热不燃烧气溶胶生成制品同等时间所产生的气溶胶的烟雾量，而且可以不需要预热，传统预热所需时间大约20秒；可以极大地提升用户的使用体验。
（2）气溶胶生成效率高：气溶胶形成剂222中的微波吸收性能良好的物质（例如丙二醇）能够直接吸收微波而气化生成气溶胶，气溶胶的生成效率高。
（3）烟草221的利用率高：通过微波加热的均匀性以及温度梯度为由内向外的特点，避免了烟草221不充分的问题，提高了烟草221的利用率。
（4）后期维护简单：在使用时，由于上述气溶胶生成部件22利用微波生成气溶胶，不需要中心加热装置，自然地也避免了清洁中心加热装置，后期维护简单。
本发明一些实施方式还提供了一种上述气溶胶生成部件22的制备方法，该制备方法包括以下步骤：
将烟草221、气溶胶形成剂222和功能粒子223混合后，制备气溶胶生成部件22。
具体地，烟草221、气溶胶形成剂222和功能粒子223的具体组成和用量如上述，此处不再赘述。此外，在一些实施例中，将烟草221、气溶胶形成剂222和功能粒子223混合后，还包括将烟草221、气溶胶形成剂222和功能粒子223形成的混合物进行成型处理。具体地，成型的工艺可以采用本领域常用的成型工艺。
上述气溶胶生成部件22的制备方法简捷，易于工业化生产。
图20示出了本发明一些实施例中的气溶胶产生装置10e，其可包括微波发生器11、与该微波发生器11相连接的雾化腔体12以及设置于该雾化腔体12内的用于固定气溶胶生成制品20的固定座13。雾化腔体12的顶壁上具有一个与外界相连通的开口120，微波发生器11用于往雾化腔体12内馈入微波。固定座13用于供气溶胶生成制品20可拆卸地固定于其中，从而让微波对气溶胶生成制品20进行微波加热。
微波发生器11在一些实施例中可包括壳体111、设置于该壳体111内的微波生成电路112以及与微波生成电路112相连接的微波发射天线113e。微波发射天线113e在一些实施例中可伸入到雾化腔体12内，并螺旋形分布于固定座13的外壁面上，用于工作时在固定座13中部形成强微波场区域。雾化腔体12内壁面还能够将微波发射天线113e向外发射的微波反射向强微波场区域，以进一步加强该强微波场区域的微波场。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
