一同参考图9至图11，在一些实施例中，内导体单元1还包括导体盘112，用于调节馈入频率（阶跃阻抗）。导体盘112用于微波传导，还可以增加自身电感和电容，以及降低谐振频率，从而利于腔体20尺寸的进一步变小。该导体盘112可呈圆盘状，导体盘112与导体柱11相连接，具体地，导体盘连接于导体柱的自由端。导体盘112的外径大于导体柱11的外径，且小于外导体单元2的内径。在一些实施例中，导体盘112可套设与导体柱11靠近开口端202一侧外，且两者之间可以为一体成型或欧姆接触。在一些实施例中，导体盘112可以由金属材料制成，或者可以是在非金属材料外表面镀有导电涂层制成。优选地，导体盘112可以采用铝合金或者铜。
辐射结构12可结合于导体柱11的自由端，该辐射结构12位于气溶胶生成制品的外侧，其可沿导体柱11与收容座3相对的端面周缘设置。在一些实施例中，辐射结构12由导电材料制成或其外表面镀有导电层。辐射结构12包括至少一个横断面呈扇形的辐射元件121，至少一个辐射元件121与收容座3对应设置，以调节腔体20的微波场分布和谐振频率。由于大部分的气溶胶生成制品为圆柱形，本发明中的辐射结构12与气溶胶生成制品的形状相匹配，故本发明的辐射元件121的横断面可均呈扇形，以贴合气溶胶生成制品的形态，从而对气溶胶生成制品进行有效加热，可以极大地提高气溶胶生成制品加热均匀性和范围。当然，辐射元件121还可以是横断面呈矩形等其他形状的，在此不作具体限制。而且，微波场一般在横断面呈扇形的辐射元件121的顶部周边最强，因此辐射结构12的辐射元件121如果接近气溶胶生成制品顶部，可实现对气溶胶生成制品顶部的优先加热，从而利于快速释放气溶胶，即有利于提升雾化速度，减少预热时间。而不同辐射元件121长度的设计，则可以使气溶胶生成制品的加热均匀性更好。
在一些实施例中，至少一个辐射元件121向上延伸至收容座3的收容部30的侧壁32，并与导体柱11的自由端欧姆接触，至少一个辐射元件121的弧度与收容部30的侧壁32的弧度相当，使微波场的均匀性得到显著提高，便于提升对气溶胶生成制品加热的均匀性。
如图3所示，在一些实施例中，辐射结构12的至少一个辐射元件121可位于收容部30的侧壁32的内侧，并与收容部30的内侧壁面贴合，至少一个辐射元件121从收容部30的底壁31伸入至收容部30的内侧壁面内。该基部122的表面积跟与导体柱11与收容部30相对的端面的表面积相当。在一些实施例中，可以在收容部30的内侧壁面设置收容槽，供至少一个辐射元件121卡入定位，使其可分布于收容部30的内侧壁面。收容部30的底壁31上可设有相应的开孔311，可供至少一个辐射元件121穿设于其中并伸入至收容部30内，且基部122与收容部30的底壁31贴合。
如图4所示，在一些实施例中，辐射结构12的至少一个辐射元件121可位于收容部30的侧壁32的内侧，并与收容部30的内侧壁面之间具有一定的间隙。该基部122的表面积小于与导体柱11与收容部30相对的端面的表面积，且立设于基部122的周向上的辐射元件121通过开孔311伸入至收容部30内，基部122与收容部30的底壁31贴合。
如图5所示，在一些实施例中，辐射结构12的至少一个辐射元件121可位于收容部30的侧壁32的外侧，至少一个辐射元件121可以与收容部30的外侧壁面贴合，或者至少一个辐射元件121与收容部30的外侧壁面间隔设置。可在收容部30的外壁面设置收容槽，供至少一个辐射元件121卡入定位，使其可分布于收容部30的外侧壁面上。
如图6所示，在一些实施例中，至少一个辐射元件121至少局部地嵌置于收容部30的侧壁32中。收容部30的侧壁32具有一定厚度，收容部30的侧壁32可以设置有由收容部30的底壁31一端向上延伸的插孔，以供至少一个辐射元件121插入，该插孔的形状大小可与至少一个辐射元件121适配。
参考图7至图14，辐射结构12在一些实施例中还包括与至少一个辐射元件121相连接的基部122，辐射结构12经由基部122与导体柱11的自由端欧姆接触。至少一个辐射元件121立设于该基部122的周向上，以使微波场更均匀地分布于收容部30的周围。该基部122的表面积可以跟导体柱11与收容部30相对的端面的表面积相当，或者小于导体柱11与收容部30相对的端面的表面积。
在一些实施例中，该基部122可设置于导体柱11与收容部30相对的端面上，且可与收容部30面向导体柱11的一面贴合，并跟导体柱11与收容部30相对的端面欧姆接触；或者基部122一体成型于导体柱11与收容部30相对的端面上。在一些实施例中，基部122一体连接于导体柱11的自由端，至少一个辐射元件121一端连接于基部122，另一端沿平行于导体柱11轴线并远离导体柱11的方向延伸。在一些实施例中，基部122可以为圆盘形、方形或多边形等其他形状，并覆盖于导体柱11与收容部30相对的端面上。在一些实施例中，基部122一体成型于一体连接的导体柱11和导体盘112的端面上。
在一些实施例中，每一横断面为扇形的辐射元件121包括本体部1211，本体部1211沿平行于导体柱11的轴线延伸设置，且本体部1211的横断面呈扇形。
图7为本发明辐射结构的第一实施例的结构示意图，在该实施例中，横断面为扇形的辐射元件121的设置数量为一个，微波场在该一个辐射元件121周围最强，随着距离辐射元件121的距离的增加而变小。辐射元件121所对应气溶胶生成制品的区域优先产生气溶胶。该一个辐射元件121的长度和宽度可以根据实际情况进行调整，同样地，其横断面扇形的弧度也可以根据实际情况进行调整。
图8为本发明辐射结构的第二实施例的结构示意图，在该实施例中，横断面为扇形的辐射元件121的设置数量为两个，其可以沿导体柱的轴线径向对称设置。在一些实施例中，该两个辐射元件121可以对称分布于收容部30的侧壁32的周向。当然，该两个辐射元件121也可以是间隔分布于收容部30的侧壁32的周向。
在一些实施例中，两个辐射元件121的本体部1211长度可以相等或不等，两个辐射元件121的本体部1211的宽度可以相等或不等。在一些实施例中，两个辐射元件121的本体部1211的弧度可以相等或不等。即该两个辐射元件121之间可以是等长不等宽的，或者是等宽不等长的，或者是等宽等长的，或者是不等宽不等长的，可根据实际情况进行组合调整，在此不作限定。
图9为本发明辐射结构的第三实施例的结构示意图，在该实施例中，两个辐射元件121中的至少一个还包括延伸部1212，延伸部1212可以沿一个圆心落在导体柱11轴线的圆弧延伸。该延伸部可以沿该圆弧的至少一端延伸，优选地，该延伸部分别沿该圆弧的两端延伸。
延伸部1212的横断面呈扇形，且该延伸部1212的横断面大于本体部1211的横断面。该延伸部1212与导体盘112的径向上下端面相平行，且其横断面投影落在导体盘112与收容座3相对的端面内。
在一些实施例中，两个辐射元件121中的一个包括延伸部1212，两个辐射元件121的本体部1211的长度不等。可以在本体部1211的长度相对较小的辐射元件121上设有延伸部1212，从而实现微波场调配。在另一些实施例中，两个辐射元件121上均包括延伸部1212，两个辐射元件121的本体部1211的长度相等，且分别设于两个辐射元件121上的延伸部1212的长度相等。在一些实施例中，延伸部1212可以设置在导体盘112远离导体柱11一侧的端面周向边缘上，并且延伸部1212的弧度可以与导体盘112的周向侧壁的弧度相当。
图10为本发明辐射结构的第四实施例的结构示意图，在该实施例中，辐射结构12包括一个横断面为扇形的辐射元件121以及一个纵长形的探针120，两者对称分布于收容部30的侧壁32的周向。该横断面为扇形的辐射元件121的长度大于该纵长形的探针的长度。
图11为本发明辐射结构的第五实施例的结构示意图，在该实施例中，辐射结构12包括两个横断面为扇形的辐射元件121以及一个纵长形的探针120，三者间隔地分布于收容部30的侧壁32的周向，且其三者的分布位置可根据实际情况进行调整。该两个辐射元件121的长度可以相等或不等，其宽度可以相等或不等，其弧度可以相等或不等。该两个辐射元件121的长度与该一个纵长形的探针120的长度可以相等或不等。
图12为本发明辐射结构的第六实施例的结构示意图，图13为本发明辐射结构的第七实施例的结构示意图，在该实施例中，横断面为扇形的辐射元件121的设置数量为三个，该三个辐射元件121等间隔地分布于收容部30的侧壁32的周向。该三个辐射元件121的长度可以相等或不等，其宽度可以相等或不等，其弧度可以相等或不等。如图12所示，在该实施例中，该三个辐射元件121的长度均相等。如图13所示，在该实施例中，该三个辐射元件121的长度均不相等。当然，在其他一些实施例中，辐射元件的长度可根据实际情况进行调整，在此不作限制。
图14为本发明辐射结构的第八实施例的结构示意图，在该实施例中，横断面为扇形的辐射元件121的设置数量为四个，该四个辐射元件121包括对与对之间长度不等的两对辐射元件121，其宽度和弧度可根据实际情况进行调整。该两对辐射元件121交替地、均匀地分布于收容部30的侧壁32的周向。该实施例中的微波场在长度相对较长的一对辐射元件121周围最强。该四个辐射元件121使得微波场分布相对均匀。
在一些实施例中，该横断面为扇形的辐射元件121可以与纵长形的探针120、横断面为非扇形的辐射元件121等元件进行组合，且其材料可以均由导电材料制成或其外表面镀有导电层。通过以上不同结构的组合，可以调配微波场，使得微波场分布相对均匀，从而有利于根据气溶胶生成制品进行雾化区域优化。
本发明的辐射结构12的形状及分布可以极大的改变腔体20内的微波场分布形态，进而对位于收容部30内的气溶胶生成制品的不同区域进行选择性的加热，微波场的均匀性得到提高，从而有效提高雾化效果。
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。
