 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。
如图1所示，本发明一个优选实施例中的雾化装置包括微波加热组件10、控制模块20、电池模块30、微波发生装置40，电池模块30与控制模块20、微波发生装置40电性连接，为控制模块20、微波发生装置40供电，让微波馈入装置5产生微波，控制模块20用于控制微波发生装置40输出的微波功率、加热时间、开停间隔等参数。
结合图2至图5所示，微波加热组件10包括腔体1、导体柱2、固定装置3、吸波加热组件4、微波馈入装置5，腔体1为一端封闭的管状，其包括侧壁11及底壁12，并为导电的金属材质，材质一般为铝、铜、金、银、不锈钢等导电金属。
在其他实施例中，也可在腔体1的内壁面上涂覆设置有第一导电层，如镀金、镀银、镀铜等等。
导体柱2设置在腔体1内的底壁12，导体柱2与腔体1底壁12相连接并导电。
优选地，本实施例中，导体柱2可以螺接在腔体1的底部，以便拆装。导体柱2为导电材料，优选地，可以为导电的金属材料，也可为其它高导电性能材料。
在其他实施例中，导体柱2也可为非金属材料，且在导体柱2的外壁面涂覆设置有第二导电层，第二导电层为镀金属薄膜层，如镀金、镀银、镀铜等等。
微波馈入装置5设置于微波发生装置40和腔体1之间，用于将微波发生装置40产生的微波传输到腔体1内，利用微波对腔体1内的雾化介质加热。
腔体1的侧壁11上设有供微波馈入的馈入孔13，微波馈入装置5一般为同轴连接器，一端与微波源微波发生装置40相连接，另一端由馈入孔13插入腔体1，当然，馈入孔13也可以位于腔体1的底壁12。
微波馈入装置5由馈入孔13插入腔体1内，并与腔体1的内壁面和/或导体柱2的表面接触导通，以向腔体1内馈入微波。
吸波加热组件4设置在腔体1内，并插接在腔体1内的雾化介质中，以吸收微波加热雾化介质，优选地，吸波加热组件4包括吸波加热片41。
以下是在有吸波加热组件4的情况下最佳馈入频率与衰减值（S11）、雾化介质温度的关系表：
吸波加热组件4的吸波材料可以吸收微波发生装置40馈入的微波，可以提升整个雾化介质雾化过程中微波馈入腔体1的效率，尤其是后半段的微波馈入效率。吸波材料的介电常数较大，从而使得等效介电常数变化较小，原因是雾化介质在加热过程中的介电常数变化，对整体的介电常数变化影响较小。
在腔体1内设置吸波加热组件4可以提升整个雾化介质的加热效果，雾化介质在加热前期，雾化介质及吸波加热片41均可吸收微波，吸波加热片41只是起到辅助加热雾化介质的作用；而在雾化介质远离导体柱2的后半段，雾化介质的微波吸收能力变得较差时，吸波加热片41是吸收微波的主力，吸波加热片41吸收微波发热进而将热量传导给雾化介质。
通过吸波加热片41的形状设计，可以改善雾化介质内的温度场分布。优选地，吸波加热片41朝向腔体1的开口端延伸，在吸收微波后向雾化介质辐射，本实施例中，吸波加热片41朝向腔体1开口端的端部为尖头或圆头，使得温度场分布更均匀。
吸波加热片41的加入，可以使整个雾化过程当中，腔体1的最佳馈入频率波动变小，从而有利于微波源电路的设计与控制。
具体地，如图4、5所示，在第一实施例中，导体柱2的端部设有供吸波加热组件4安装的安装槽21，让吸波加热片41设置在导体柱2上，在雾化介质插入腔体1内时，吸波加热片41插入到雾化介质的内端，向雾化介质内辐射热量。
