以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、技术之类的具体细节，以便透彻理解本发明实施例。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施例中也可以实现本发明。在其它情况中，省略对众所周知的系统、装置、电路以及方法的详细说明，以免不必要的细节妨碍本发明的描述。
本发明构造了一种气溶胶产生装置，该气溶胶产生装置可利用微波加热气溶胶生成制品2（参考图3），以雾化产生气溶胶，从而供使用者吸食或吸入。该气溶胶生成制品2为诸如经过处理的植物叶类制品等固态的气溶胶生成制品2。可以理解地，该气溶胶生成制品2也可以为液态的气溶胶生成制品2。
该气溶胶产生装置可包括微波发生装置（未图示）以及第一微波加热组件1（参考图1）。微波发生装置用于产生微波，产生的微波可馈入至第一微波加热组件1中，在其腔体111内形成一个微波场，该微波场中强微波的区域作为加热区域，作用于布置在该加热区域中的部分气溶胶生成制品2。
如图1所示，该第一微波加热组件1的整体形状大致呈圆柱状，当然，第一微波加热组件1并不局限于圆柱状，其也可呈方柱、椭圆柱状等其他形状。
如图2所示，第一微波加热组件1可包括第一外导体单元11、设于第一外导体单元11内的第一内导体单元12以及介质（例如，空气），还包括装于第一外导体单元11上的微波馈入单元13。第一外导体单元11可界定出一个腔体111，作为微波加热的场所。微波馈入单元13将微波发生装置产生的微波馈向至第一外导体单元11和第一内导体单元12上，第一内导体单元12对腔体111中的谐振频率及微波分布进行调节，从而实现对气溶胶生成制品2的微波加热。
如图2所示，第一外导体单元11呈圆筒状，可界定出一个半封闭式、呈圆柱状的腔体111；当然，腔体111并不局限于圆柱状，其也可呈方柱、椭圆柱状等其他形状。其次，该第一外导体单元11还设有一个与腔体111相连通的通孔1131，该通孔1131可略大于或者等于气溶胶生成制品2的外径，以供气溶胶生成制品2插入至腔体111中。
在该实施例中，第一外导体单元11可采用可导电的金属材料一体制成，金属材料优选导电导热性高铝合金或铜；也可以采用通过在非导电筒体的内壁面镀覆第一导电涂层的方式实现，制成第一导电涂层的材料可包括金、银、铜、铝、导电金属氧化物（ITO、AZO、AGZO、FTO等）、导电高分子等，优选金或银。可以理解地，为了减少加热过程当中的热损失以及解决第一外导体单元11的发烫问题，优选采用非导电筒体的内壁面镀覆第一导电涂层的方式，以降低壁电流产生的热损耗。
如图3所示，第一外导体单元11可包括导电的导体侧壁112、第一端壁113和第二端壁114。该导体侧壁112呈圆筒状，其顶端和底端均为开口结构。第一端壁113用于封盖导体侧壁112的顶端，同时上述的通孔1131轴向贯穿第一端壁113，居中地形成于第一端壁113上，从而形成第一外导体单元11的第一开口端。第二端壁114用于封堵导体侧壁112的底端，形成第一外导体单元11的第一封闭端。可以理解地，在气溶胶生成制品2插入第一外导体单元11内时，其邻近第二端壁114的端面（制品端面21）可抵接于第二端壁114与所述第一端壁113相对的端面（内侧端面1141），使气溶胶生成制品2立于内侧端面1141上。
此外，为了防止气溶胶生成制品2的制品端面21完全接触于第二端壁114，导致气流流动不畅通，可在制品端面21与所述内侧端面1141之间形成第二进气间隙1142；同时，该第二进气间隙1142还可以防止在加热过程中，气溶胶生成制品2的热量大量传递给第一外导体单元11。可选地，可在第二端壁114上可设置轴向贯穿的一个或多个细小的第一穿孔（可参考实施例8中的第二穿孔1145），该些第一穿孔形成第二进气间隙1142。还可以在内侧端面1141上设置至少一个第二凸起1143和/或至少一个第二凹槽（未图示），该些第二凸起1143和/或第二凹槽（未图示）的形状可以相同或者不相同，第二端壁114借由该些第二凸起1143和/或第二凹槽，在与制品端面21之间形成第二进气间隙1142。
此外，该导体侧壁112靠近第一端壁113处设有一个径向贯通的馈入孔1121，该馈入孔1121可供微波馈入单元13插设至第一外导体单元11内。该馈入孔1121的孔径与微波馈入单元13的外导体131的外径相适配。
如图3所示，该第一内导体单元12设置于第一外导体单元11的腔体111中，其轴向高度略小于第一外导体单元11的腔体111的轴向高度；第一内导体单元12的顶部结合于第一外导体单元11在通孔1131的周边位置，其底部悬空于腔体111中，与第一外导体单元11的底部和内周壁之间均存在间距。通过该第一内导体单元12的设计，可使得整个第一微波加热组件1小型化，有效降低腔体111整体的高度。
该第一内导体单元12在腔体111内形成一个固定空间123；该固定空间123可供气溶胶生成制品2插入第一外导体单元11内时顺势穿设于其中，同时，固定空间123的内壁面可接触于气溶胶生成制品2的周面，来防止气溶胶生成制品2的位置发生偏移，从而起到固定气溶胶生成制品2的作用。
可选地，该第一内导体单元12可采用导电的金属材料一体制成，优选铝合金或铜。当然，第一内导体单元12并不局限于采用导电材料一体制成，其也可以通过在非导电体的外表面镀覆第二导电涂层的方式实现。第二导电涂层优选镀覆银涂层或者金涂层。
如图4所示，第一内导体单元12为非全封闭的结构，其包括一个导体部121和一体结合于该导体部121的一个延伸部122。
优选地，该导体部121呈圆筒状，其内径小于或等于第一外导体单元11的通孔1131的口径，且该内径还与气溶胶生成制品2的直径相适配，以起到夹持固定气溶胶生成制品2的作用。该导体部121包括相背的、呈圆环形的第一表面1211和第二表面1212，以及贯穿所述第一表面1211和所述第二表面1212的穿设通道1213；第一表面1211共轴地结合于所述第一外导体单元11的第一端壁113上，且穿设通道1213与第一外导体单元11的通孔1131连通。可选地，第一表面1211可以一体结合于第一外导体单元11，或者，第一表面1211与第一外导体单元11欧姆接触。
该延伸部122呈纵长的弧形结构，自导体部121的第二表面1212，以平行于导体部121的轴线的方向朝第一外导体单元11的第二端壁114延伸。该延伸部122的横断面呈弧形，其内凹周壁面与第一外导体单元11的纵轴线相对，且其弧度与气溶胶生成制品2外周面的弧度相适配。
可以理解地，由于大部分的气溶胶生成制品2为圆柱形，故将本发明的延伸部122构造为弧形结构，与气溶胶生成制品2的形状相匹配，以贴合气溶胶生成制品2的形态，从而对气溶胶生成制品2进行有效加热，可以极大地提高气溶胶生成制品2加热均匀性和范围。当然，延伸部122不仅仅局限于呈弧形结构，其还可以是其他结构，比如直条形结构、曲线形结构等等，也可以是弧形结构、直条形结构、曲线形结构它们中至少一种的组合。
在该实施例中，该延伸部122包括一个固定端1221和一个自由端1222，该固定端1221一体结合于导体部121的第二表面1212，而该自由端1222则沿背离于所述第一表面1211的方向延伸，且其与第一外导体单元11的第二端壁114之间具有细小的间距。同时，导体部121的外周面、延伸部122的周面与第一外导体单元11的内周面之间也具有间距。
可以理解地，导体部121的内周壁面和延伸部122的内凹周壁面在腔体111内形成上述的固定空间123。在气溶胶生成制品2插入至腔体111中时，导体部121的内周壁面贴合于气溶胶生成制品2在周向上的外周侧面，同时，延伸部122的内凹周壁面贴合于气溶胶生成制品2在轴向上的部分外周侧面，以起到限制气溶胶生成制品2的位置和固定气溶胶生成制品2的作用。
在该实施例中，第一内导体单元12上还设有一个供微波馈入单元13的一端插入的插孔（未图示），该插孔沿垂直于第一外导体单元11的轴向，设置于导体部121或者延伸部122上，且其孔口与馈入孔1121相对。插孔的孔径与微波馈入单元13插入的一端的直径相适配。可选地，该插孔的形状可以是圆形、方形、椭圆或者其他多边形。
在该实施例中，该第一内导体单元12不仅可用于实现对气溶胶生成制品2的微波加热和固定气溶胶生成制品2，还可以提供气道以及实现测温控温的功能。
优选地，在该第一内导体单元12的导体部121的内周壁面设置至少一个第一凸起（未图示）和/或至少一个第一凹槽（未图示），该些第一凸起和/或第一凹槽的形状可以相同或者不相同。导体部121的内周壁面借由该些第一凸起和/或第一凹槽，在其和气溶胶生成制品2的外周面之间形成第一进气间隙，方便在气溶胶生成制品2被抽吸时空气可以流进第一外导体单元11中。
在导体部121上沿竖直方向打孔，形成一个用于收容测温元件的容纳孔（未图示），该容纳孔穿过导体部121延伸至延伸部122的底部中电场强度最强的位置（一般自由端1222处的电场强度最强）。将测温元件的测温探头插入至该电场强度最强的位置，来对微波加热时的气溶胶生成制品2进行测温和控温，测温探头与位于第一微波加热组件1外部的控温测温电路（未图示）电性连接。优选地，第一内导体单元12优选采用热导率高的金属材料制成，更优选为导电导热性高的铝合金或者铜的材料制成；其次，导体部121的内壁面和延伸部122的内凹周壁面优选与气溶胶生成制品2的外周面紧密接触，从而保证测温控温的精确性。
可以理解地，相较于相关技术中需要依赖于探针151来实现测温控温的方式，本发明通过由第一内导体单元12来实现测温控温的功能，避免了抽吸结束后需要清洁探针151的问题，并且完善了使用者的使用体验。其次，该容纳孔并非本第一微波加热组件1的必要技术特征，其作为一个优选方案应用于本实施例中。当无需第一内导体单元12实现测温控温的功能时，可以选择不开设容纳孔；同时在该情况下，可选择在耐高温的非金属体的表面（耐高温塑料、陶瓷等）镀有导电涂层（金、银、铜、铝、导电金属氧化物（ITO、AZO、AGZO、FTO等）、导电高分子等）来制成第一内导体单元12。需要说明的是，耐高温为能够耐受高于250°的温度，进一步为高于350°。
如图3所示，微波馈入单元13可为同轴连接器，从第一外导体单元11的馈入孔1121处安装在第一外导体单元11上，其馈入的方式可以为电馈入方式或磁馈入方式，优选电馈入方式。
该微波馈入单元13包括筒状的外导体131、设置在外导体131中的内导体132以及介于内导体132和外导体131之间的介质层133。微波馈入单元13安装于馈入孔1121处时，其内导体132与第一内导体单元12欧姆接触，且其外导体131与馈入孔1121的内壁面欧姆接触。
在该实施例中，外导体131呈圆筒状，其两端均为开口结构。内导体132呈一字型，沿垂直于第一外导体单元11的轴线方向插入至第一内导体单元12的插孔中，以与第一内导体单元12紧密接触，形成良好的欧姆接触。
可以理解地，相关技术一般采用在第一外导体单元11内设置收容座来固定气溶胶生成制品2的方式，该收容座采用非金属材料制成。然而，收容座在微波加热时会吸收较多的微波能量，导致气溶胶生成制品2的微波吸收效率相应降低，其碳化效果变差，且出烟速度也会变慢。
而本发明实施例1中的第一内导体单元12兼顾固定气溶胶生成制品2的功能，使得第一外导体单元11内部可以仅包含有第一内导体单元12，馈入至第一微波加热组件1的微波能量基本可以被气溶胶生成制品2所吸收，规避了相关技术中采用收容座所带来的技术问题，还有利于提高气溶胶生成制品2的微波能量吸收效率，提高气溶胶生成制品2整体抽吸后的碳化效果，以及降低功耗和成本。
在该实施例中，第一微波加热组件1在装配有气溶胶生成制品2的情况下，谐振频率可处于2.4-2.5GHz以内。
一并再参阅图5，图5示出了本发明在实施例2中的第二内导体单元12a。该实施例是在实施例1的基础进行的改进，具体是将第二内导体单元12a替代了上述实施例1的第一内导体单元12。该第二内导体单元12a与上述第一内导体单元12的结构基本相同（导体部121和延伸部122的结构相同），其两者的区别在于，第二内导体单元12a中包括两个延伸部122，该两个延伸部122沿导体部121的轴线镜像对称，等间隔地分布在所述导体部121的周向上。
一并再参阅图6，图6示出了本发明在实施例3中的第三内导体单元12b。该实施例是在实施例1的基础进行的改进，具体是将第三内导体单元12b替代了上述实施例1的第一内导体单元12。该第三内导体单元12b与上述第一内导体单元12的结构基本相同（导体部121和延伸部122的结构相同），其两者的区别在于，第三内导体单元12b包括两对延伸部122，该两对延伸部122交替地、均匀地分布于所述导体部121的周向上。在该两对延伸部122中，同一对的延伸部122的长度相等，且沿导体部121的轴线镜像对称分布在所述导体部121的周向上，非同一对的延伸部122的长度不等。
一并再参阅图7，图7示出了本发明在实施例4中的第四内导体单元12c。该实施例是在实施例1的基础进行的改进，具体是将第四内导体单元12c替代了上述实施例1的第一内导体单元12。该第四内导体单元12c与上述第一内导体单元12的区别在于，第四内导体单元12c的导体部121的轴向长度大于第一内导体单元12的导体部121的轴向长度，且第四内导体单元12c的延伸部122的轴向长度小于第一内导体单元12的延伸部122的轴向长度。同时，第四内导体单元12c包括了四个延伸部122，该四个延伸部122的形状大小均相同，其四者等间隔地分布在所述导体部121的周向上。
一并再参阅图8，图8示出了本发明在实施例5中的第五内导体单元12d。该实施例是在实施例2的基础进行的改进，具体是将第五内导体单元12d替代了上述实施例2的第二内导体单元12a。该第五内导体单元12d与上述第二导体结构的区别在于，第五内导体单元12d中两个延伸部122之其一者上设有呈方形的镂空部126，该镂空部126可利于增强内导体单元的局部微波场强度，且利于提高气溶胶生成制品2的加热均匀性。可以理解地，镂空部126的形状不仅局限于方向，其形状还可包括圆形、方形、曲线形或者其他多边形形状。
一并再参阅图9，图9示出了本发明在实施例6中的第六内导体单元12e。该实施例是在实施例4的基础进行的改进，具体是将第六内导体单元12e替代了上述实施例4的第四内导体单元12c。该第六内导体单元12e与上述第四内导体单元12c的区别在于，第六内导体单元12e中的导体部121上设有多个呈方形的镂空部126，该些镂空部126等间隔地分布在所述导体部121的周向上。
可以理解地，当延伸部122包括至少两个时，导体部121的内周壁面和延伸部122的内凹周壁面所形成的固定空间123可以更好地固定气溶胶生成制品2。同时，根据延伸部122的长度和/或数量的改变，微波场的分布也会随之进行调整，可根据实际需求来设置延伸部122的长度和/或数量。其次，当需要内导体132结构实现测温控温功能时，可将容纳孔设置在内导体132结构中电场强度较强的延伸部122中，以提高测温控温的精确性。
一并再参阅图10所示，图10示出了本发明在实施例7中的第七内导体单元12f。该实施例是在实施例1的基础进行的改进，具体是将第七内导体单元12f替代了上述实施例1的第一内导体单元12。该第七内导体单元12f与上述第一内导体单元12的区别在于，该七内导体132结构包括共轴地设置于第一外导体单元11内的导体柱127f。该导体柱127f呈筒状，其外径小于或等于第一外导体单元11的通孔1131的口径，且其轴向高度略小于第一外导体单元11的腔体111的轴向高度。
在该实施例中，如图11所示，该导体柱127f包括相对的的第二开口端1271f和第三开口端1272f。第二开口端1271f朝向第一外导体单元11的通孔1131，且其共轴地结合于第一外导体单元11的第一端壁113上。结合的方式可以是第二开口端1271f一体结合于第一外导体单元11上，或者第二开口端1271f与第一外导体单元11欧姆接触。该第三开口端1272f沿第一外导体单元11的第二端壁114的方向延伸，且与第二端壁114之间保持有间距。
该导体柱127f的中空通道1273f相当于上述的固定空间123，该中空通道1273f与通孔1131相连通，以供气溶胶生成制品2穿过通孔1131后伸入至中空通道1273f，并对气溶胶生成制品2起到限位的作用。此外，该导体柱127f的内径小于或等于第一外导体单元11的通孔1131的口径，且与气溶胶生成制品2的外径相适配，使得导体柱127f的内周壁面紧贴合于气溶胶生成制品2的外周面，以起到夹持固定气溶胶生成制品2的作用。
可选地，该导体柱127f可采用导电的金属材料一体制成，优选铝合金或铜。当然，导体柱127f并不局限于采用导电材料一体制成，其也可以通过在非导电体的外表面镀覆第二导电涂层的方式实现。第二导电涂层优选镀覆银涂层或者金涂层。
一并再参阅图12所示，图12示出了本发明在实施例8中的第二外导体单元11a。该实施例是在实施例2的基础进行的改进，具体是将第二外导体单元11a替代了上述实施例1的第一外导体单元11。
如图13所示，该第二外导体单元11a与上述实施例1的第一外导体单元11的结构基本相同，其同样包括可导电、呈直圆筒状的导体侧壁112、封堵于导体侧壁112顶端的第一端壁113和封堵于导体侧壁112底端的第二端壁114；同样地，第二外导体单元11a的导体侧壁112靠近第一端壁113处设有一个径向贯通的馈入孔1121，在第一端壁113上也设有居中轴向贯穿的通孔1131。
该第二外导体单元11a与上述实施例1的第一外导体单元11的区别在于，在第二外导体单元11a的第二端壁114与第一端壁113相对的端面（内侧端面1141）上设有凹部1144。如图13所示，该凹部1144呈圆柱形通道，其沿背离于第一端壁113的方向居中地凹陷于内侧端面1141，且其槽口与通孔1131相对；该凹部1144的直径可略大于或者等于气溶胶生成制品2的外径。当气溶胶生成制品2依次穿过通孔1131和固定空间123后可插入凹部1144中，插入至凹部1144的部分气溶胶生成制品2不容易被加热到，使得在加热气溶胶生成制品2过程且产生气溶胶时，减少冷凝液在内导体132结构的延伸部122上形成，从而进一步提高第二外导体单元11a内部的洁净度。此外，第二端壁114还设有轴向贯穿凹部1144槽底的一个或多个细小的第二穿孔1145。该第二穿孔1145的作用与第一穿孔1142的作用相同，在这不做赘述。
一并再参阅图14所示，图14示出了本发明在实施例9中的第二微波加热组件1a。该实施例是在实施例2的基础进行的改进，具体的区别在于，该第二微波加热组件1a通过设置一个用于装载气溶胶生成制品2的第一收容座14a，替代了实施例2中由第一外导体单元11的第二端壁114来承托的技术方案。同时，该第二微波加热组件1a还包括一个用于测温控温的探针装置15。可以理解地，第一收容座14a和探针装置15可根据实际需要进行选配。
第一收容座14a采用低微波损耗的材料制成，该可减少延伸部122在加热气溶胶生成制品2产生气溶胶时冷凝液的产生，进一步提高腔体111内部的洁净度。可选地，低微波损耗的材料可包括PI、PEEK、PTFE等材料。
在该实施例中，如图14所示，第一收容座14a装于第二内导体单元12a的底部，其可配合第二内导体单元12a的两个延伸部122将气溶胶生成制品2的下部结构包裹起来，同时还可以起到承托起气溶胶生成制品2的作用。
优选地，如图15和图16所示，第一收容座14a大致呈圆筒状，包括一个第二封闭端141a和一个第四开口端142a。第二封闭端141a位于第二内导体单元12a的延伸部122与第一外导体单元11的第二端壁114之间，且与第二端壁114之间保持有间隙。第四开口端142a朝向第一外导体单元11的通孔1131。在第一收容座14a的外周壁面上设有供第二内导体单元12a的延伸部122插入的两个卡槽143a；该两个卡槽143a均呈纵长的弧形通道，沿第一收容座14a的轴线镜像对称；其两者分别贯穿第一收容座14a在开口端的端面，以平行于第一收容座14a轴向的方向朝第二封闭端141a处延伸，卡槽143a的底壁面与第二封闭端141a之间具有间距。
在第一收容座14a装于第二内导体单元12a的底部时，两个延伸部122分别卡合于两个卡槽143a中，且延伸部122在周向上的侧边平面和其底面贴合于卡槽143a的内壁面，此时第一收容座14a与第二内导体单元12a分别在第一外导体单元11的第二端壁114上的两个投影部分/完全重合。两个延伸部122的内凹壁面和第一收容座14a的内周面一并界定出一个周向和底部封闭的收容腔，该收容腔将气溶胶生成制品2的下部结构容纳于其中，收容腔的底部贴合于气溶胶生成制品2的制品端面21。
可以理解地，卡槽143a的数量以及形状大小分别与延伸部122的数量以及形状大小相对应。当然，当第一收容座14a需要与实施例3中的第三内导体单元12b组合时，第一收容座14a可以选择在对应相对较长的一对延伸部122的位置处开设卡槽143a。
在该实施例中，第一收容座14a还可包括若干个纵长的定位筋（未图示）。这些定位筋间隔均匀地设置于收容腔的内壁面周向上。每一定位筋均沿着平行于第一收容座14a的轴线的方向延伸。该些定位筋在一个方面可用于夹紧插入收容腔的气溶胶生成制品2，在另一个方面每相邻两定位筋之间均形成一个纵向延伸的第一进气通道，以方便环境空气被吸入到气溶胶生成制品2的底部，再进入气溶胶生成制品2中带走被微波加热产生的气溶胶。
第一收容座14a还可包括若干纵长的支撑筋（未图示）；这些支撑筋均匀间隔地呈放射状分布于收容腔的底面上。可以理解地，支撑筋一个方面用于支撑气溶胶生成制品2，另一个方向形成若干放射状第二进气通道。这些第二进气通道分别与上述那些第一进气通道相连通，以方便环境空气被吸入到气溶胶生成制品2的底部，再进入气溶胶生成制品2中带走被微波加热产生的气溶胶。
在该实施例中，探针装置15用于实现测温控温功能，以提高温度测试的响应时间和测温的精度，防止第二内导体单元12a的延伸部122底端的微波场过强，控温不及时而导致气溶胶生成制品2加热过度，继而产生糊味，可进一步提高气溶胶生成制品2的加热均匀性。其次，由于第二内导体单元12a的延伸部122底端具有较强的微波场分布，在延伸部122与探针装置15的组合搭配下可以防止探针装置15处的微波场过于集中（过强），从而降低出现气溶胶生成制品2生成制品容易烧糊或打火的问题的几率。
如图16所示，该探针装置15包括纵长、中空的探针151以及位于探针151内的测温元件（未图示）。该探针151竖直地设置在第一外导体单元11中，且与第一外导体单元11一体结合或者欧姆接触；内导体132结构的延伸部122环绕于探针151的外周，且延伸部122的内凹壁面与探针151的外壁面之间保持有间距。优选地，该探针151的一端共轴地固定于第一外导体单元11的第二端壁114，其另一端穿过第一收容座14a在第二封闭端141a的端壁，向第一外导体单元11的通孔1131处延伸；探针151向通孔1131延伸的一端至多延伸至与通孔1131齐平。探针151的直径小于气溶胶生成制品2的直径，在气溶胶生成制品2伸入腔体111内时，气溶胶生成制品2插于探针151上，且位于探针151的外周。测温元件可以与位于第二微波加热组件1a外部的控温测温电路（未图示）电性连接，以监测并反馈气溶胶生成制品2内部的温度情况。
可选地，探针151向通孔1131延伸的一端的形状包括平面、球形、椭球形、圆锥形或者圆台形；优选圆台形。因为可以起到增强局部场强的作用，从而提升气溶胶生成介质的雾化速度。
探针151在一些实施例中可采用导电的金属材料一体制成，优选不锈钢、铝合金或铜。可以理解地，探针151并不局限于采用导电材料一体制成，其也可以通过在非导电体的外表面镀覆第三导电涂层的方式实现。第三导电涂层可包括金、银、铜、铝、导电金属氧化物、或者导电高分子；其中，导电金属氧化物包括ITO、AZO、AGZO、FTO材料；优选镀覆银涂层或者金涂层。
本发明还包括在实施例10中的第三微波加热组件（未图示）。该实施例是在实施例9的基础进行的改进，具体是将第二收容座14b（未图示）替换了上述实施例9的第一收容座14a。
第二收容座装于第二内导体单元12a的底部，用于将气溶胶生成制品2的下部结构完全包裹起来以及承托起气溶胶生成制品2。
在该实施例中，第二收容座呈圆筒状，其内径大于导体部121的外径，且其周侧壁可环绕于部分/所有延伸部122的外周。第二收容座可包括一个第三封闭端和一个第五开口端。第三封闭端邻近于第一外导体单元11的第二端壁114，且与之保持有间隙；第五开口端朝向第一外导体单元11的通孔1131。
在第二收容座装于第二内导体单元12a的底部时，部分/所有延伸部122伸入第二收容座中，且延伸部122伸入至第二收容座中的部分结构的外周壁面以及延伸部122的底面与第二收容座的内壁面相贴合。此时，第二收容座在第一外导体单元11的第二端壁114上的投影位于第二内导体单元12a在第二端壁114上的投影的外周。
本发明还包括在实施例11中的第四微波加热组件（未图示）。该实施例是在实施例9的基础进行的改进，具体是将第三收容座（未图示）替换了上述实施例9的第一收容座14a。
第三收容座装于第二内导体单元12a的底部，用于将气溶胶生成制品2的下部结构完全包裹起来以及承托起气溶胶生成制品2。
在该实施例中，第三收容座呈圆筒状，其外径小于导体部121的内径，可设置于部分/所有延伸部122的内周。第三收容座可包括一个第四封闭端和一个第六开口端。第四封闭端邻近于第一外导体单元11的第二端壁114，且与之保持有间隙；第六开口端与第一外导体单元11的通孔1131相对。
在第三收容座装于第二内导体单元12a的底部时，部分/所有延伸部122环绕于第三收容座的外周，且延伸部122中环绕于第三收容座的部分结构的内凹壁面与第三收容座的外周壁面相贴合。第四封闭端的内壁面与延伸部122的底部持平。此时，第三收容座在第一外导体单元11的第二端壁114上的投影位于第二内导体单元12a在第二端壁114上的投影的外周。
可以理解的，以上实施例仅表达了本发明的优选实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制；应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，可以对上述技术特点进行自由组合，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，凡跟本发明权利要求范围所做的等同变换与修饰，均应属于本发明权利要求的涵盖范围。
