 本发明的最佳实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
在一优选实施例中，参考图1，本实施例的电子雾化装置用于加热雾化气溶胶生成基质，气溶胶生成基质可为固体烟草、液态烟油等。该电子雾化装置包括雾化腔、微波控制电路、微波生成电路、微波发射天线和反馈采集电路，雾化腔用于收容气溶胶生成基质；微波控制电路分别连接微波生成电路和反馈采集电路，微波生成电路连接微波发射天线。
该电子雾化装置的工作过程为：微波控制电路确定预设微波频率，控制微波生成电路按预设微波频率生成微波。微波发射天线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以加热气溶胶生成基质。需要说明的是，微波发射天线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实现，微波控制电路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。
进一步，反馈采集电路在微波发射天线发射微波后采集微波发射天线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，微波控制电路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基质达到最佳雾化状态。作为选择，选择气溶胶生成基质吸收最多的微波发射频率作为最优微波发射频率，电子雾化装置以该最优微波发射频率发射微波，直至下一次微波扫频。
本实施例使用微波直接加热气溶胶生成基质，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。
在一实施例的电子雾化装置中，反馈信号为反馈电流值，反馈采集电路为电流采集电路，电流采集电路将目标对象在微波作用下产生的感应电流值作为反馈电流值。
在一实施例的电子雾化装置中，反馈信号为反馈电压值，反馈采集电路为电压采集电路，电压采集电路将目标对象在微波作用下产生的感应电压值作为反馈电压值。
在一实施例的电子雾化装置中，反馈信号为反馈电容值，反馈采集电路为电容采集电路，电容采集电路将目标对象在微波作用下产生的感应电容值作为反馈电容值。
在一实施例的电子雾化装置中，反馈信号为反馈温度值，反馈采集电路为温度采集电路，温度采集电路采集目标对象在微波作用下的温度值。作为选择，目标对象可为气溶胶生成基质，温度采集电路采集气溶胶生成基质在微波作用下的温度值。
在一实施例的电子雾化装置中，参考图2，反馈信号为反向微波功率，反馈采集电路为微波反向功率检测器。微波发射后，并非所有微波都会被气溶胶生成基质吸收，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。作为选择，微波发射天线作为未吸收微波的接收端，微波反向功率检测器检测微波发射天线接收的反向微波功率，微波发射天线吸收部分未被气溶胶生成基质吸收的微波，微波反向功率检测器检测微波发射天线吸收微波的功率得到反向微波功率。进一步，得到反向微波功率后，微波控制电路根据反向微波功率选择最优微波发射频率，例如微波控制电路选择反向微波功率最小值所对应的微波发射频率，或微波控制电路选择反向微波功率最小值所对应的微波发射频率附近范围的微波发射频率。
在一实施例的电子雾化装置中，参考图3，本实施例的电子雾化装置还包括与微波控制电路连接的微波正向功率检测器，微波正向功率检测器用于采集微波发射功率。微波控制电路可根据微波发射功率和反向微波功率选择最优微波发射频率，例如根据反向微波功率和微波发射功率的比值选择最优微波发射频率，选择反向微波功率和微波发射功率的比值最小时对应的微波发射频率。
在一实施例的电子雾化装置中，参考图4，本实施例的电子雾化装置还包括功率放大器，微波生成电路的输出端连接功率放大器的第一输入端，功率放大器的输出端连接微波发射天线；微波控制电路连接功率放大器，微波控制电路根据反馈信号调整功率放大器。可以理解的，微波控制电路可控制功率放大器的放大倍数。
在一实施例的电子雾化装置中，参考图5，本实施例的电子雾化装置还包括功率调节器，微波控制电路连接功率调节器的输入端，功率调节器的输出端连接功率放大器的第二输入端，微波控制电路根据反馈信号调整功率调节器。可以理解的，功率放大器和功率调节器可以为两个独立电子元件，也可为集成电子元件，该集成电子元件可实现功率放大器和功率调节器两种功能。作为选择，微波控制电路根据反馈信号同时调整功率放大器和功率调节器，实现微波更大范围的发射功率调整。
在一优选实施例中，本实施例的电子雾化装置是加热不燃烧电子雾化装置。参考图6和图7，在该实施例中，加热不燃烧电子雾化装置包括气溶胶生成基质10、基质固定架20、雾化腔30、微波发射天线40、电路板50、供电电池60和壳体70，其中基质固定架20用于放置和固定气溶胶生成基质10，微波生成电路、反馈采集电路和微波控制电路集成在电路板50上，供电电池60用于为加热不燃烧电子雾化装置供电，电路板50和供电电池60位于壳体70内。可以理解，基质固定架20使用微波能够穿透的材质，以避免吸收微波。微波发射天线40具有多种安装位置，本实施例举例进行说明。
图6中，微波发射天线40位于雾化腔30底部，靠近壳体70安装，雾电子雾化装置还包括微波聚集装置80，微波发射天线40位于微波聚集装置80内。微波发射天线40发出微波，微波聚集装置80将微波发射天线40发射的至少部分微波聚集至雾化腔30中气溶胶生成基质10所在位置，以加热气溶胶生成基质10。作为选择，微波聚集装置80的内层为微波反射层，使用微波反射层能更好的将微波聚集至雾化腔30，提高微波利用率，提高加热效率。进一步，微波聚集装置80的外层为微波屏蔽层，屏蔽层能吸收未被利用的微波，防止微波散射到加热不燃烧电子雾化装置外，产生微波污染。
图7中，微波发射天线40缠绕在雾化腔30或基质固定架20上，微波发射天线40发出微波，该方式发射的微波多数已集中在雾化腔30内，即集中在气溶胶生成基质10上，部分向周围发散的微波经微波聚集装置80反射后重新聚集在气溶胶生成基质10，以加热气溶胶生成基质10。
在一优选实施例中，参考图8，本实施例的微波控制方法应用于如上述实施例的电子雾化装置中。具体的，该微波控制方法包括下述步骤：
S1、微波控制电路控制微波生成电路生成微波，使微波发射天线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中的气溶胶生成基质。具体的，微波控制电路确定预设微波频率，控制微波生成电路按预设微波频率生成微波。微波发射天线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以加热气溶胶生成基质。需要说明的是，微波发射天线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实现，微波控制电路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。具体的，反馈采集电路在微波发射天线发射微波后采集微波发射天线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。
S3、扫频发射微波结束后，微波控制电路根据反馈信号选择微波发射频率。具体的，扫频发射微波结束后，微波控制电路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基质达到最佳雾化状态。作为选择，选择气溶胶生成基质吸收最多的微波发射频率作为最优微波发射频率，电子雾化装置以该最优微波发射频率发射微波，直至下一次微波扫频。

一实施例的微波控制方法中，微波加热加热不燃烧电子雾化装置在生产过程中会导致微波聚集装置存在误差，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。
一实施例的微波控制方法中，因每种气溶胶生成基质对应的微波频率不同，即每种气溶胶生成基质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、微波控制电路接收到气溶胶生成基质安装完毕指令，即在用户新安装或更换气溶胶生成基质后，产生气溶胶生成基质安装完毕指令，
一实施例的微波控制方法中，随着气溶胶生成基质的消耗，气溶胶生成基质需要加热的位置不断变化，为使微波能准确加热气溶胶生成基质，在步骤S1之前还包括：S103、微波控制电路接收到抽吸指令，用户每次抽吸时产生抽吸指令。
一实施例的微波控制方法中，随着气溶胶生成基质的消耗，气溶胶生成基质需要加热的位置不断变化，为使微波能准确加热气溶胶生成基质，在步骤S1之前还包括：S104、微波控制电路每间隔预设抽吸时间。
