所述感受器还包括基座部分，所述气雾生成装置通过该基座部分对所述感受器提供保持。

当然进一步从图7中可以看出，当存在多个缺口33c时，这些缺口 33c的布置方式是具有差异的，具体第一缺口331c是由感受器30c的上端沿长度方向延伸，而第二缺口332c是由感受器30c的上端沿长度方向延伸，从而使得具有不同的开口朝向；并且当存在多个缺口33c时，第一缺口331c和第二缺口332c是沿感受器30c的周向方向交替布置的，进而在检测的过程中使通过感受器30c的电流具有图7中箭头所示的迂回弯折的电流路径，从而提升检测的电阻值的大小。
或者在又一个变化实施中，参见图8所示，感受器30d呈管状形状，所述感受器30d内表面的至少一部分形成所述腔室，所述感受器30d具有两个相同的由下端朝上端延伸的缺口33d，进而将感受器30d分隔成沿周向方向位于两个缺口33d之间的两个部分，即图7中左半部分310d和右半部分320d；同时使第一引脚31d和第二引脚32d分别在靠近或下端的位置与左半部分310d和右半部分320d连接，从而形成图7中箭头所示的迂回的电流路径。
在又一个优选的实施中，以上第一引脚31/31a/31b/31c和第二引脚32/32a/32b/32c采用具有电阻温度系数的材质制备，例如常用的热电偶丝包括镍铁铜合金、镍铬铝合金、镍铬铜合金、铂、钨等等；则在检测的过程中，检测的是感受器30/30a/30b/30c与第一引脚31/31a/31b/31c和第二引脚32/32a/32b/32c的合并电阻阻值，则可以使得在检测中能通过对感受器30/30a/30b/30c的电阻进行放大，提升阻值和温度检测的结果。在实施中，由于采用具有电阻温度系数的第一引脚31/31a/31b/31c和/或第二引脚32/32a/32b/32c放大感受器30/30a/30b/30c的电阻，需要使第一引脚31/31a/31b/31c和/或第二引脚32/32a/32b/32c具有相同的类型的；比如采用的具有以上铁磁材质的感受器30/30a/30b/30c是正向的电阻温度系数，当温度升高时其电阻阻值也相应提升，同样第一引脚31/31a/31b/31c和/或第二引脚32/32a/32b/32c也需要是正向的电阻温度系数。
在更加优选的实施中，为了避免以上第一引脚31/31a/31b/31c和第二引脚32/32a/32b/32c与感受器30/30a/30b/30c之间存在温度差，进而在制备中采用将第一引脚31/31a/31b/31c和第二引脚32/32a/32b/32c通过超 声波碰焊的工艺与感受器30/30a/30b/30c进行焊接，尽可能消除差异。
或者在更优选的实施中，以上第一引脚31包括由两段材质制备，具体参见图9所示，包括有沿长度方向依次设置的第一部分311和第二部分312；其中，第一部分311是采用具有相对高的电阻温度系数的材质制备，比如以上常用的热电偶丝包括镍铁铜合金、镍铬铝合金、镍铬铜合金、铂、钨等，用于在检测中对感受器30/30a/30b/30c的电阻进行放大，提升阻值和温度检测的结果；而第二部分312采用低电阻率的材质制备，其目的是使第二部分312在使用中的温度低于第一部分311的温度，从而防止高温对后续焊接电路20等造成热损伤；进一步第二部分312还需要具有高的导电和焊接性能，能便于良好地与电路20焊接，比较适合的材质如金、银、铜等。
本申请实施例还提出一种对于具有以上感受器30/30a/30b/30c/30d的气雾生成装置控制其生成气溶胶的方法，参见图10所示，包括如下步骤：
S10，通过第一供电模块22向电感线圈L提供交变电流，激励作为磁场发生器的电感线圈L产生变化的磁场，使感受器30发热进而对可抽吸材料A进行加热；
S20，通过第二供电模块23向感受器30提供直流检测电压；
S30，测量感受器30在直流检测电压下的电阻值，并从所述电阻值确定感受器30的温度；
S40，基于以上所确定的感受器30的温度，调整提供给电感线圈L的交变电流的功率、频率或占空比的至少一种，进而调节产生的交变磁场，以使感受器30能保持在预设的目标温度。
在图11所示的实施例中，与上述实施例不同的是，气雾生成装置还包括用于布置电感线圈L和感受器30的管状支架50，如图11至图12所示，该管状支架50的材质可以包括耐高温非金属材料比如PEEK或者陶瓷等。在实施中，电感线圈L采用缠绕的方式布置在管状支架50的外壁上。
基于提升感受器30的便捷固定安装、更换和清理的灵活性，进一 步参见图12和图13所示，管状支架50内设置有沿径向方向设置的内径尺寸较管状支架50的内径相对减小的分隔部51，通过该分隔部51将管状支架50内部的空间分成上、下两个部分，分别为第一容纳部510和第二容纳部520；根据这一构造，第一容纳部510被配置为用于容纳可抽吸材料A的上述腔室，并且当可抽吸材料A容纳于第一容纳部510时，其前端抵接在分隔部51上实现支撑和保持，提供对可抽吸材料A的止动。
感受器30则对应进行构造调整，感受器30包括感受部分，被配置为被所述变化的磁场穿透而发热，进而对接收在所述腔室内的可抽吸材料的至少一部分进行加热；感受部分包括沿轴向方向在第一容纳部510内延伸的呈销钉或者刀片状的加热部310，当可抽吸材料A容纳于第一容纳部510内时，加热部310可以插入至可抽吸材料A内从而对可抽吸材料A的内部进行加热；同时，感受器30还包括容纳于第二容纳部520内的基座部320，该基座部320的外形与第二容纳部520适配从而接触紧密。当然基座部320用于方便感受器30安装和固定，可以较为便捷地将其在第二容纳部520内保持；同时根据这一实施方式，分隔部51上具有供加热部31贯穿的穿孔511，使加热部31的一端与基座部32连接、另一端延伸至第一容纳部510内。
在一个优选的实施方式中，为了能准确监测感受器30的温度、并控制使其处于在合适的加热温度范围，参见图11所示，气雾生成装置还包括具有正向或者负向的电阻温度系数的导电轨迹40；在实施中，通过将该导电轨迹40与感受器30的感受部分导热接触的方式进行布置，并将其耦合接入电路20；而后电路20即可通过测量导电轨迹40的电阻确定感受器30的温度。
以上导电轨迹40优选地可由金属形成，该金属包括合适的固有材料特性，用于提供作为温度函数的电阻的线性近似。优选实施中，合适金属的示例包括铂(Pt)、钛(Ti)、铜(Cu)、镍(Ni)或含有它们的各种合金。在其他的变体实施例中，导电轨迹40也可由任何其它金属形成，这种金属具有相对大的电阻温度系数(α)并且作为温度的函数而不会有显著 波动。图15示出了一个实施例中由铂镍铬合金通过丝网印刷制备的具有正向电阻温度系数的导电轨迹40的电阻随温度变化的曲线图。
根据图12所示的优选实施方式中，导电轨迹40是通过打印、印刷、蚀刻、沉积、电镀等方式结合在感受器30上形成导热，进而在感受器30感应发热时热量能直接从感受器30传递至导电轨迹40使两者的温度一致或者接近一致，进一步在温度的变化下引起导电轨迹40的电阻发生变化，进而即可通过测量导电轨迹40的电阻获得感受器30的温度。
基于避免影响可抽吸材料A在与加热部310的结合和移除的操作中引起对导电轨迹40的磨损，在图2所示的实施例中，采用将导电轨迹40结合于基座部320这一部分上。或者在其他的变化实施中，导电轨迹40采用通过以上所述的打印、印刷、蚀刻、沉积、电镀等的方式结合于呈销钉或者刀片状的加热部310的至少一部分表面上。
同时进一步在更加优选的实施中还可以在导电轨迹40裸露的外表面上通过喷涂、溅射、沉积等方式形成一保护膜层，该保护膜层的材质可以采用玻璃、陶瓷、釉等，厚度控制约1～50μm；防止在制备、装配过程中对导电轨迹40碰撞刮擦等导致的导电轨迹40产生损伤。
根据图12所示的优选的实施方式中，导电轨迹40的两端设置有电连接部，该电连接部通过焊接感受器30两端的导电引脚，即可实现与电路20的便捷连接。
在又一个实施例中，导电轨迹40与感受器30是绝缘的，则由金属或者合金制备的感受器30不影响导电轨迹40的电阻测量的过程。在实施中，可以使感受器30的表面或者至少与导电轨迹40结合的表面通过氧化、涂覆等方式形成一层比如釉、氧化物等的绝缘层，进而与导电轨迹40绝缘。
或者在图14所示的又一个变形实施中，将导电轨迹40a形成于第二容纳部520的内壁上，进而使其与容纳在第二容纳部520内的基座部320导热接触；同时，将导电轨迹40a的两端焊接上导电引脚的方式，即可接入电路20，从而通过测量导电轨迹40a的电阻计算感受器30的温度。 则在该实施中，将导电轨迹40a与管状支架50制备形成一体的方式，而后安装感受器30后形成组件模块，生产制备和测温上更加快捷和准确。
在图16所示的又一个实施例中，示出了具有管状形状的感受器30b管状感受器30b被同轴布置在管状支架50b的中空内并与电感线圈L感应耦合，管状感受器30b的内部空间形成用于容纳可抽吸材料A的腔室。同时，基于检测管状感受器30b的温度，导电轨迹40b被通过打印、印刷、蚀刻、沉积、电镀等的方式形成在管状感受器30b的外表面上，如图15所示；或者在其他变化中，导电轨迹40b还可被形成于管状支架50b的内壁上，则当管状感受器30d被布置在管状支架50d内时即可与导电轨迹40d导热接触，从而实现温度监测的目的。
在更加优选的实施中，当导电轨迹40a/40b被通过以上方式形成于管状支架50的内壁上时，为了保证导电轨迹40a/40b分别能与感受器30/30b导热接触的稳定性和紧密性，可以在管状支架50的内壁表面上先形成一弹性介质层比如具有柔性的树脂、硅胶等的弹性材料，或者是例如聚酰亚胺膜(PI膜)的绝缘的柔性载体材料等，再将导电轨迹40a/40b形成于管状支架50内壁上，则通过弹性层的柔性力使导电轨迹40a/40b与管状感受器30b的外表面接触紧密，防止刚性接触导致存在缝隙而造成导热效果不稳定。
本申请实施例还提出一种用于监测电磁感应式加热的气雾生成装置温度的方法，气雾生成装置的示例可以参见图11所示，包括：腔室，可抽吸材料A可移除地接收在腔室内；
电感线圈L，用于在交变电流下产生变化磁场；
感受器30，至少一部分在腔室内延伸，并被配置为与电感线圈L感应耦合，在被变化磁场穿透下发热，进而对可抽吸材料A例如烟支进行加热，使可抽吸材料A的至少一种成分挥发，形成供抽吸的气溶胶；
电芯10，为可充电的直流电芯，可以输出直流电流；
电路20，通过适当的电连接到可充电的电芯10，用于从将电芯10输出的直流电流，转变成具有适合频率的交变电流再供应到电感线圈L；
温度监测方法步骤参见图18所示，包括：
S50，提供与感受器30导热接触的导电轨迹40；导电轨迹40具有正向或者负向且的电阻温度系数；
S60，测量导电轨迹40的电阻并通过测量的电阻确定感受器30的温度。
本申请实施例还提出一种用于电磁感应加热式气雾生成装置的感受器30b，如图17所示；可在被变化的磁场穿透下感应发热，该感受器30b上形成有导热连接并相互绝缘的导电轨迹40b，该导电轨迹40b具有正向或者负向且的电阻温度系数，进而使得可以通过检测该导电轨迹40b的电阻值确定感受器的温度。
在一个优选的实施方式中，为了能准确监测感受器30的温度、并控制使在安装过程中对与其接触的部件具有更低的热损；感受器30的细节构造上参见图16所示，加热部310包括：
电绝缘衬底3101，在图16中被构造呈可插入至可抽吸材料A内的销钉或者是刀片的形状；在实施中，电绝缘衬底3101可以与基座部分320是一体制备的，材料比如氧化铝、氧化锆陶瓷等、或者是刚性的耐温聚合物树脂、或者是通过绝缘处理后的金属基体等等。
沉积或者喷涂、或者通过卷绕或包裹等方式结合于电绝缘衬底3101外的感受材料层3102；感受材料层3102在一个可选的实施中是通过PVD沉积或者等离子喷涂等方式形成于电绝缘衬底3101上的涂层；该感受材料层3102的材质可以采用具有适当磁导率的感应发热金属或者合金材料，进而使其可以被电感线圈L产生的磁场诱导而发热；在实施中，感受材料层3102的厚度可以优选低于0.2mm甚至更薄，例如当采用磁导性能优秀的材质如坡莫合金时，能满足形成集肤效应厚度即大于2.8微米既可实现。
进一步在优选的实施中，感受材料层3102在电绝缘衬底3101上的延伸长度被作为磁场发生器的电感线圈L的长度覆盖，即感受材料层3102基本是完全位于电感线圈L内的。并且感受材料层312的长度是能完全覆盖导电轨迹40的，使得更加均匀。
进一步与感受材料层3102导热连接的导电轨迹40通过导电引脚与电路20耦合。具体地，导电连接部两端的电连接部通过导电引脚与电路20耦合，进而在使用中，电路20可以通过对导电轨迹40两端的电压和电流进行采样计算即可得出导电轨迹40的电阻。以上结构的加热部310中，感受材料层3102在感应发热时热量能直接从感受材料层3102传递至导电轨迹40使两者的温度一致或者接近一致，而导电轨迹40在温度变化时电阻会相应产生变化，进而即可通过测量导电轨迹40的电阻获得感受材料层3102的温度。
例如图19所示的优选实施，导电轨迹40被构造成是围绕电绝缘衬底3101和/或感受材料层3102、并沿电绝缘衬底3101和/或感受材料层3102的轴向延伸的螺旋形状。
当然在以上实施中，导电轨迹40与感受材料层3102是相互绝缘的，以防止电路20在测量导电轨迹40的电阻时产生干扰。具体可以通过在导电轨迹40与感受材料层3102之间通过设置绝缘层(图中未示出)的方式实现，比如在制备的过程中先对感受材料层3102的表面沉积或喷涂一层比较薄的玻璃/釉等绝缘的保护层，而后再形成上述导电轨迹40。
在又一个可变的优选实施中，导电轨迹40是形成于电绝缘衬底3101与感受材料层3102之间的，即感受材料层3102相对是位于导电轨迹40外的；在使用中通过使感受材料层3102位于导电轨迹313外，可以使感受材料层3102沿径向方向的内部区域大约是磁场屏蔽的区域，而导电轨迹40处于该区域磁场屏蔽的区域内自身不被交变磁场诱导产生电流，防止干扰其电阻测量。
进一步基于阻止感受器30使用中的磨损，同时加热部310的最外表面上还可以通过喷涂、溅射、沉积等方式形成一保护膜层，该保护膜层的材质可以采用玻璃、陶瓷、釉等，厚度控制约1～50μm。
在又一个可选的实施中，感受材料层3102是作为金属箔施加于电绝缘衬底3101的外表面上的。
进一步根据图19所示的优选的实施，感受材料层3102沿感受器30的轴向方向，与基座部分320保持有一定的间距形成保持区域3103。在 使用中支架50的分隔部51是保持或者连接在该保持区域3103部位上的，并且在装配后感受材料层3102与支架50的分隔部51是相对错开并不相互接触的；进而避免感受材料层3102的热量通过接触式传递至支架50的分隔部51上。
上述的导电轨迹40可以通过如图17所示在薄片状的陶瓷生胚的平坦表面上通过印刷、沉积、打印等方式形成，为方便导电轨迹40焊接导电引脚，导电轨迹40的两端形成有低电阻系数的电连接部分41，电连接部分41的材质可以采用低电阻系数的银、金、银钯合金等等。
上述的感受材料层3102的方式还可以采用图18所示的方式进行，具体：将一根内径略小于电绝缘衬底3101外径的中空金属管3102a加热，加热到产品使用的最高温度(比如大于350℃)，使金属管3102a发热膨胀后套设在带有导电轨迹40的电绝缘衬底3101表面；冷却后，中空金属管3102a紧固在电绝缘衬底3101表面，形成与导电轨迹40紧密导热接触的感受材料层3102。
或者在其他的可变实施中，将上述的中空金属管3102a还可以替换成中空的针或者销钉的形状。
本申请又一实施例还提出一种制备用于气雾生成装置的感受器30的方法，具体包括如下步骤，参见图19至图21所示：
S70，获取薄片状的陶瓷生胚，可以是直接购买获得的柔性氧化铝或氧化锆等陶瓷纸；
S80，如图20所示在薄片状的陶瓷生胚的平坦表面上通过印刷、沉积、打印等方式形成导电轨迹40；当然，为了便于后续导电轨迹40焊接导电引脚，导电轨迹40的两端形成有低电阻系数的电连接部分41，电连接部分41的材质可以采用低电阻系数的银、金、银钯合金等等；
在可选的实施中，印刷形成的导电轨迹40的厚度为10～30微米左右。
S90，获取图19中销钉形状的陶瓷材质的电绝缘衬底3101，再将步骤S80制备的形成有导电轨迹40的薄片状的陶瓷生胚卷绕于销钉形状的电绝缘衬底3101表面后，再通过等静压或者烧结固化的方式形成一 体，形成如图22所示的带有导电轨迹40的电绝缘衬底3101；基于实施的情形，还可以在电连接部分41的两端焊接上导电引脚；
S100，获取一用于形成感受材料层3102的金属箔，通过卷绕工艺缠在步骤S90固化后的带有导电轨迹40的电绝缘衬底3101表面，然后通过焊接工艺将金属箔卷绕后接缝焊接在一起，在焊接过程中使金属箔牢固结合在电绝缘衬底3101表面，形成管状的感受材料层3102。完成之后，还可以通过表面喷涂保护层等，即获得用于气雾生成装置的感受器30。
或者在又一个可变的实施中参见图23所示，感受器30b包括呈刀片状的电绝缘衬底3101b；电绝缘衬底3101b具有沿厚度方向相对的两个表面，即图23中电绝缘衬底3101b的上表面和下表面；其中，上表面形成有用于感测感受器30b的温度的导电轨迹40b，而相对的下表面上形成有感受材料层3102b。在该实施中，电绝缘衬底3101b可以采用导热系数相对较高的材料，使整体的温度趋于均匀，保持加热过程中与可抽吸材料A的热量传递大致上均匀，并减小导电轨迹40b测温的误差。
以上气雾生成装置及感受器，在响应磁场加热可抽吸材料的同时能准确地检测感受器的温度；相比温度传感器的测温方式在生产制备更便捷、测温效果更准确。
需要说明的是，本申请的说明书及其附图中给出了本申请的较佳的实施例，但并不限于本说明书所描述的实施例，进一步地，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本申请所附权利要求的保护范围。
