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。
图1至图9示出了本发明一些实施例中的气溶胶产生装置100，该气溶胶产生装置100可利用微波加热气溶胶生成基质200，以雾化产生气溶胶，从而供使用者吸食或吸入。在一些实施例中，该气溶胶生成基质200为诸如经过处理的植物叶类制品等固态气溶胶生成基质200。可以理解地，在另一些实施例中，该气溶胶生成基质200也可以为液态气溶胶生成基质200。
再如图1至图3所示，该气溶胶产生装置100在一些实施例中可包括微波加热器1、固定座2以及微波馈入装置3。微波加热器1在一些实施例中可呈 圆柱状，其可包括一个让微波于其内持续振荡的加热腔13。固定座2可固定地或可拆卸地安装于微波加热器1上，用于在气溶胶生成基质200插入微波加热器1时固定气溶胶生成基质200，防止在抽吸过程中气溶胶生成基质200的位置发生偏移。微波馈入装置3连接于微波加热器1上，用于将微波发生装置(未图示)产生的微波馈入加热腔13中，使得加热腔13中形成微波场；气溶胶生成基质200伸入加热腔13的部分结构可暴露于微波场中，被微波加热雾化。
可以理解地，微波加热器1并不局限于圆柱状，其也可呈方柱、椭圆柱状等其他形状。
在一些实施例中，微波加热器1可包括谐振器，比如四分之一波长型同轴线谐振器。
参阅图2-图4所示，微波加热器1在一些实施例中可包括用于实现电磁屏蔽的筒状外导体单元11、设置于该外导体单元11中以导波的纵长内导体单元12以及介于该内导体单元12的外壁面和外导体单元11的内侧壁面之间的介质(例如，空气)，外导体单元11和内导体单元12一道界定出上述的加热腔13。
内导体单元12的第一端(固定端)与外导体单元11的第一端壁112欧姆接触，形成该微波加热器1的短路端1A。内导体单元12的第二端(自由端)向外导体单元11的开口延伸，并不与外导体单元11直接欧姆接触，形成该微波加热器1的开路端1B。在一些实施例中，内导体单元12的轴线与外导体单元11的轴线相互重合或平行，优选地，两者相互重合。
固定座2安装(例如，可拆卸或不可拆卸地)于该微波加热器1的开路端1B，并且，将该固定座2远离微波场设置，使得固定座2处于弱微波场或者 非微波场区域，尽可能地避免固定座2吸收微波，影响气溶胶生成基质的加热效果。
外导体单元11在一些实施例中可包括可导电的第一侧壁111、可导电的第一端壁112、以及第一开口110。第一侧壁111在一些实施例中可呈圆筒状，其包括第一端以及与该第一端相对的第二端。第一端壁112封闭于该第一侧壁111的第一端上，形成外导体单元11的一个封闭端。第一开口110形成于第一侧壁111的第二端上，形成外导体单元11的一个开口端，用于供收容座嵌置于其中。外导体单元11的第一侧壁111靠近第一端壁112处可设置一个径向贯通的馈入孔1110，以供微波馈入装置3安装于其中。
外导体单元11在一些实施例中可采用可导电的金属材料一体制成，其材质可包括铝、铜、金、银、不锈钢中的至少一种；优选铝合金或铜。可以理解地，外导体单元11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、导电金属氧化物或者导电高分子；其中导电金属氧化物可包括ITO、AZO、AGZO和FTO材料。优选第一导电涂层为银涂层或者金涂层。
另外，外导体单元11并不局限于圆筒状，其也可以呈方筒状、椭圆筒状等其他适合的形状。
如图3、图4以及图7所示，内导体单元12在实施例1-1中，可包括导体柱121、导体盘123和探针装置122。
其中，该导体柱121呈圆柱形，其包括邻近外导体单元11的第一端壁112的底端、以及与底端相背的顶端；该底端作为内导体单元12的第一端，抵接于外导体单元11的第一端壁112上并与其欧姆接触；该顶端的端面朝向外导 体单元11的开口端。
导体盘123设于导体柱121的顶端，与导体柱121一体成型或者形成良好的欧姆接触。导体盘123的直径大于导体柱121的直径。探针装置122的一端从该导体盘123的顶端插入并贯穿导体盘123，嵌置于导体柱121的内部，使得探针装置122与导体柱121和/或导体盘123形成良好的欧姆接触；该探针装置122的另一端悬空于加热腔13中。
导体盘123包括顶端盘面以及底端盘面。顶端盘面朝向开口端设置，可在气溶胶生成基质200伸入加热腔13时抵接气溶胶生成基质200的第一端面201，起到支撑作用。同时，在该顶端盘面与第一端面201相抵时，该两者之间形成有进气间隙128，用于防止气溶胶生成基质200的第一端面201完全贴合于顶端盘面，导致气流无法从该第一端面201进入至气溶胶生成基质200中。底端盘面朝向导体柱121的顶端，并与导体柱121连接。
顶端盘面呈高低不平的面结构，以与第一端面201相抵时形成进气间隙128。在一些实施例中，顶端盘面包括平面125、以及高出于平面125高度的凸面126；第一端面201在伸入加热腔13时可抵接于凸面126，使得第一端面201与平面125之间留有一定的间距，形成进气间隙128。可以理解地，在顶端上设有向开口端方向凸起的一个凸起部1261，该凸起部1261可将顶端盘面包括有凸面126和平面125；同时，凸起部1261与第一端面201分别在顶端盘面上的投影部分重合；或者；凸起部1261含于第一端面201在顶端盘面上的投影中，以确保可以留有进气间隙128。此外，该凸起部1261还可以防止在加热过程当中，气溶胶生成基质200的热量会大量传递给加热腔13内。当然，凸起部1261的数量还可以是两个以上，在这不作数量的限定。在凸起部1261的数量包括两个以上时，多个凸起部1261可以绕导体柱121的中轴线环 形间隔排布。
可选地，凸起部1261与导体柱121一体成型，以方便制造。
凸起部1261的形状在这不做具体限定，只要能够提供进气间隙128即可。
凸起部1261采用导电材料制成，以能改变微波场分布，使得位于第一端面201的微波场强较大。
在另一些实施例中，如图8所示，顶端盘面包括平面125、以及低于平面125高度的凹面127；第一端面201在伸入加热腔13时可抵接于平面125，使得第一端面201与凹面127之间留有一定的间距，形成进气间隙128。可以理解地，在导体盘123的顶端上设有向封闭端方向凹陷的一个凹槽1271，该凹槽1271将顶端盘面包括有凹面127和平面125；同时，凹槽1271与第一端面201分别在顶端盘面上的投影部分重合，使得第一端面201只能覆盖凹槽1271的部分槽口，以确保气流可以从槽口依次进入凹槽1271内和第一端面201。当然，凹槽1271的数量还可以是两个以上，在这不作数量的限定。在凹槽1271的数量包括两个以上时，多个凹槽1271可以绕导体柱121的中轴线环形间隔排布。凹槽1271的形状在这不做具体限定，只要能够提供进气间隙128即可。
在导体柱121的底部还设有向第一端壁112方向延伸的连接部129，该连接部129可穿设于外导体单元11的封闭端，从而将导体柱121固定在外导体单元11的第一端壁112上。
在一些实施例中，该导体柱121、导体盘123、探针装置122以及外导体单元11共轴设置。探针装置122作为独立的结构，可抽离/插入导体盘123中。
导体柱121可采用可导电的金属材料一体制成，优选铝合金或铜。在另一些实施例中，导体柱121可以是外体部211导电，比如在外周面镀覆第二导电涂层，优选镀覆银涂层或者金涂层。
导体盘123可采用可导电的金属材料一体制成，优选铝合金或铜。在另一些实施例中，导体柱121可以是外体部211导电，比如在外周面镀覆第三导电涂层，优选镀覆银涂层或者金涂层。
探针装置122整体呈纵长的杆状结构，其一端从该导体柱121的顶端端面插入并嵌置于该导体柱121的内部，以与导体柱121欧姆接触；其另一端悬空于加热腔13中，可作为内导体单元12的第二端。气溶胶生成基质200伸入加热腔13中时可套设于探针装置122的外周，微波能够经由导体柱121传导给探针装置122，并作用于气溶胶生成基质200，实现微波加热的效果。
如图5示出了在实施例1-2中的内导体单元12，该实施例与上述的实施例1-2的区别在于，该实施例中还包括与导体柱121欧姆接触或者一体成型的环形导体盘124。
该环形导体盘124设于导体盘123的下方，且环绕在导体柱121的外周壁。环形导体盘124的数量可以是一个或者多个；在环形导体盘124的数量为一个时，环形导体盘124间隔地排布在导体盘123的下方。当环形导体盘124的数量为多个时，多个环形导体盘124位于导体盘123的下方、沿导体柱121的轴向间隔排布在导体柱121的外周壁。
导体盘123和环形导体盘124、和/或多个环形导体盘124之间的尺寸和厚度可以不一样，具体可根据实际情况进行调整。
如图9示出了在实施例1-3中的内导体单元12，该实施例与实施例1-1相比，区别在于，在导体柱121的顶端取消了导体盘123，并改为通过导体柱121的顶端端面抵接第一端面201。其中，导体柱121的底端抵接于外导体单元11的第一端壁112上，且导体柱121的顶端朝向开口端设置，可在气溶胶生成基质200伸入加热腔13时抵接气溶胶生成基质200的第一端面201。导体柱121 的顶端端面呈高低不平的面结构，具体结构可参考实施例1-1中顶端盘面的结构，在这不做具体赘述。可以理解地，导体盘123的设计是用于增加自身电感以及电容，从而使得气溶胶产生装置100的整体尺寸进一步地缩小。没有导体盘123也可以实现微波加热。
探针装置122的一端居中地插入该导体柱121的顶端端面，并嵌置于导体柱121的内部，使得探针装置122与导体柱121形成良好的欧姆接触；该探针装置122的另一端悬空于加热腔13中。
如图10示出了在实施例1-4中的内导体单元12，该实施例与实施例1-3相比，区别在于，导体柱121的顶端端面为平面结构。可以理解地，导体柱121顶端的直径小于第一端面201的直径时，可不设置凸起部1261或者凹槽1271；直接将导体柱121的顶端端面作为与第一端面201相抵的表面。导体柱121的顶端与第一端面201形成朝下的台阶，从而形成进气间隙128。
如图11示出了在实施例1-5中的内导体单元12，该实施例与实施例1-4相比，区别在于，导体柱121与气溶胶生成基质200各自的中轴线并非位于同一直线。可以理解地，第一端面201与导体柱121的顶端端面部分错开，形成朝下的台阶，从而形成进气间隙128。
综上，内导体单元12被配置为用于抵接气溶胶生成基质200；同时，通过设置凸起部1261和/或凹槽1271、设置内导体单元12中用于抵接气溶胶生成基质200的表面的直径小于第一端面201、设置表面与第一端面201部分错开设置等等的手段，避免第一端面201被完全覆盖，从而形成出进气间隙128。
如图2所示，探针装置122在一些实施例中可包括呈纵长的、且为实心结构的探针1221；探针1221用于调节微波场分布及最佳微波馈入频率。探针1221的外表面可导电设置，其底端嵌置于导体柱121和/或导体盘123中，以与导 体柱121和/或导体盘123形成良好的欧姆接触，其顶端悬空于加热腔13中，且该顶端的形状可以是平顶、球形、椭球形、圆锥形、圆台形等。
可以理解地，通过优化中空探针1221的顶部的形状，可以增强微波场局部场强，提升雾化气溶胶生成基质200的雾化速度；其中当中空探针1221的顶部为圆台形时，效果最佳。
在另一些实施例中，探针1221呈中空结构，在探针1221内设有测温组件，该测温组件用于在气溶胶生成基质200插入中空探针1221时，监测气溶胶生成基质200内部的温度。可选地，测温组件可为温度传感器，比如测温热电偶。
探针1221可采用金属等导电材料制成，优选不锈钢、铝合金或者铜作为导电材料。在其他一些实施例中，探针1221也可以是非导电材料表面(耐高温塑料、陶瓷等)镀有第四导电涂层；该第四导电涂层的材料可包括金、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；优选第四导电涂层为金或银。
如图2、图3所示，固定座2在一些实施例中可包括固定主体21以及设于固定主体21内的中空通道22。
固定主体21设置在外导体单元11的开口端处，远离微波场设置。
可以理解地，一同参照表格1、表格2；表格1示出了相关技术中设有收容部(收容部采用Peek材料制成)的气溶胶产生装置100，在不同温度下的谐振频率变化，以及在不同温度下气溶胶生成基质200的吸收微波情况；表格2示出了本发明中固定座2远离微波场设置后的气溶胶产生装置100在不同温度下的谐振频率变化，以及在不同温度下气溶胶生成基质200的吸收微波情况。
可以看出，在相关技术中，收容部与气溶胶生成基质200之间存在竞争吸 收微波的关系。随着加热和抽吸过程的进行，气溶胶生成基质200的介电损耗能力变弱，而，收容部却无明显变化；因此在加热的后半程，，收容部会吸收更多的微波能量，进而降低微波加热气溶胶生成基质200的效果。因此，需要尽量确保在微波场中只存在有被加热的气溶胶生成基质200，避免存在其他损耗微波的吸波部件；从而使到进入加热腔13的微博能够充分地被气溶胶生成基质200吸收，提升气溶胶生成基质200的碳化效果。

表格2
固定主体21可包括设于外导体单元11外的外体部211、以及与外体部211一体连接、设于外导体单元11内的内体部212；该外体部211和内体部212分别呈圆筒状，且外体部211的外径大于内体部212的外径，使得外体部211与内体部212之间形成台阶。内体部212的外径小于外导体单元11的内径，其可嵌入于外导体单元11中，以将固定座2装于外导体单元11的开口端上；且台阶可抵接外导体单元11的开口端，避免固定座2过分嵌入在外导体单元11内。
中空通道22可沿固定主体21的轴向贯穿成形，且与加热腔13相连通；气溶胶生成基质200可通过中空通道22伸入至加热腔13中。
固定座2在一些实施例中还包括若干纵长的定位筋213。该些定位筋213间隔均匀地设置于中空通道22的壁面轴向上。每一定位筋213均沿着平行于固定座2的轴线的方向延伸。可以理解地，该些定位筋213一个方面可用于夹紧穿过中空通道22的气溶胶生成基质200，另一个方面每相邻的两定位筋213之间，均可形成一个纵向延伸的进气通道，以方便位于外导体单元11外的环境空气被吸入到气溶胶生成基质200的底部，再进入气溶胶生成基质200中，从而带走被微波加热产生的气溶胶。
制成固定座2的材质可包括高分子材料、陶瓷材料、金属或者玻璃材料。高分子材料包括聚四氟乙烯(PTFE)、聚醚醚酮(PEEK)、ppsu、pc、ABS、pp材料；陶瓷材料包括氧化铝、氧化锆。其中，固定座2优选成本低、导热系数低的高分子材料制成。
再如图2所示，微波馈入装置3在一些实施例中可为同轴连接器，可与设于外导体单元11外部的微波源(未图示)相连接，以将微波馈入腔体。
具体地，图3示出了在一些实施例中的微波馈入装置3，其包括内导体31、 外导体33以及介于内导体31和外导体33之间的介质层32。微波馈入装置3安装于微波加热器1上时，其内导体31与外导体单元11的内壁面和/或内导体单元12的导体柱121的外表面欧姆接触，且其外导体33与外导体单元11的表面欧姆接触，以向微波加热器1内馈入微波。
在该实施例中，微波馈入装置3的内导体31呈一字型，微波馈入装置3安装于微波加热器1上时，内导体31与导体柱121的表面欧姆接触，且与导体柱121的轴线相垂直。
图6示出了在另一些实施例中的微波馈入装置3，其与上述气溶胶产生装置100的结构基本相同，两者的区别在于用第二微波馈入装置3a替代了上述的微波馈入装置3。
如图6所示，第二微波馈入装置3a可为同轴连接器，其可包括第二内导体31a、第二外导体33a以及介于第二内导体31a和第二外导体33a之间的第二介质层32a。第二微波馈入装置3a安装于微波加热器1上时，其第二内导体31a与外导体单元11的内壁面欧姆接触，且其第二外导体33a与外导体单元11的表面欧姆接触，以向微波加热器1内馈入微波。
第二微波馈入装置3a的第二内导体31a在该实施例中呈L型，其可包括一个垂直于微波加热器轴线的第一段311a和平行于微波加热器轴线的第二段312a，第二段312a与外导体单元11的第一端壁112欧姆接触。
进一步地，内导体31和/或第二内导体31a在一些实施例中可采用金属等导电材料制成，优选铝或者铜作为导电材料。在其他一些实施例中，内导体31和/或第二内导体31a也可以由非导电材料制成，但需要在其外壁面涂覆第五导电涂层形成，该第五导电涂层为镀金属薄膜层，如镀金层、镀银层、镀铜层等等。此外，在一些实施例中，内导体31和/或第二内导体31a可以是耦合 环，耦合环的外体部211呈同轴结构，可与微波源相连接，以将微波馈入腔体。
可以理解地，结合上述对于微波加热器1及其加热腔13的设计，在气溶胶生成基质200装于气溶胶产生装置100时，谐振频率可达到在2.4-2.5GHz的范围区间内。
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。
