具体实施方式
为了便于理解本申请，下面结合附图和具体实施方式，对本申请进行更详细的说明。
本申请的一实施例提出的气雾生成装置，其构造可以参见图1至图3所示，其用于接收气溶胶生成制品A例如烟支并对其进行加热，使其至少一种挥发性成分挥发形成供吸食的气溶胶；基于功能所需，结构和功能组成上包括：
壳体，整体形状大致呈内部为中空的长筒状；其中，壳体由沿长度方向依次设置的上壳体10和下壳体20共同配合形成。壳体具有沿长度方向相对的近端110和远端120；在使用中近端110用作为靠近用户进行气溶胶生成制品A的抽吸和操作的端部。
进一步上壳体10在近端110的表面上设置有接收孔11，在使用中气溶胶生成制品A可通过该接收孔111接收于壳体内被加热或移除。
进一步参见图2所示，在使用中上壳体10与下壳体20是可移除的结合的；下壳体20具有靠近近端110的外径减小的部分21，用于在将上壳体10结合至下壳体20、或者将上壳体10从下壳体20上移除的操作中提供引导。
进一步参见图3所示，通过上壳体10从下壳体20上移除的操作实现气溶胶生成制品A的提取，使气溶胶生成制品A与加热器件分离。具体上壳体10上设置有一个用于容纳和保持气溶胶生成制品A的筒状提取器30，在使用中气溶胶生成制品A被容纳和保持在该筒状提取器30；当上壳体10沿着图3中箭头R1从下壳体20进行移除时，则筒状提取器30可以携带所保持的气溶胶生成制品A从下壳体20内移出，便于用户进行气溶胶生成制品A的提取。
根据图3，气雾生成装置是通过电磁感应发热的方式加热气溶胶生成制品A的；具体，
下壳体20内设置有腔室22，用于界定接收和加热气溶胶生成制品A的加热空间；
感受器60，在图中呈沿腔室22内延伸的销钉或片状的形状，当气溶胶生成制品A在筒状提取器30的保持下接收于腔室22内时，该感受器60可以插入至气溶胶生成制品A内进行加热。具体，感受器60采用感受性材料制备，比如坡莫合金、不锈铁等，被配置为与变化磁场耦合，进而能被变化的磁场穿透而发热进而加热可抽吸材料A。
感应线圈50，围绕筒状提取器30的至少一部分设置，用于在向其提供交变电流时产生穿透感受器60的变化磁场。
在图3所示的优选实施中，感应线圈50是被固定和保持在筒状提取器30外的。进而可以当上壳体10被移除时，感应线圈50能随着上壳体10一同从下壳体20的腔室22内移除。
基于完整的实施，下壳体20内设置有：
用于供电的电芯23；
电路24用于在电芯23和感应线圈50之间引导电流，进而向感应线圈50输出交变电流，使感应线圈50产生交变磁场；以及，
充电接口25，用于为电芯23充电。
为了对保持于筒状提取器30上的感应线圈50供电，在可选的实施中，筒状提取器30的构造参见图4至图6所示，包括：
靠近近端110的外径较大的部分31，该外径较大的部分31比其他部分的外径尺寸大，该较大的部分31是通过铆压或热压或注塑等方式与上壳体10连接为一体，进而随着上壳体10在用户的移除操作下致动筒状提取器30。
在其他的可选实施中，上壳体10通过相对下壳体20移动一定的行程距离使筒状提取器30提取气溶胶生成制品A，而非完全与下壳体20 脱离。通过使筒状提取器30移动一定距离，气溶胶生成制品A与感受器60基本松动或大体分离，即可便于用户取出操作。
筒状提取器30的上端与接收孔11是连通的、下端端部构造成为封闭端，进而用于当气溶胶生成制品A被接收在内部时抵靠在封闭端的内壁上形成止动；筒状提取器30的下端端部上具有孔眼33，用于供感受器60贯穿后插入至内部的气溶胶生成制品A中；在可选的实施中，孔眼33可以包括呈适配片状感受器60形状的狭长细缝、也可以适配销钉状感受器60的圆孔、以及图6中所示的它们的组合能同时适配片状和销钉状的感受器60。
沿筒状提取器30的长度方向于外侧表面延伸的第一保持槽32；该第一保持槽32内用于安装和保持片状导电元件40；当然，第一保持槽32的数量有两个，沿筒状提取器30的径向方向对称布置在筒状提取器30的外表面上，其中一个用于容纳和保持正极导电片410、另一个用于容纳和保持负极导电片420。正极导电片410和负极导电片420均是薄片的形状，大约具有不超过1mm的厚度，材质采用高导电性能的金、银、铜或它们的合金。
进一步详细参见图5和图6，筒状提取器30的下端端部表面上还设置有第二安装槽34；正极导电片410和负极导电片420均呈片状的形状，主要部分呈竖直延伸、并在下端具有沿水平延伸的正极触头部分412和负极触头部分422；在装配后它们分别主要被保持于第一保持槽32内，并且使正极触头部分412和负极触头部分422分别保持于第二安装槽34内并呈裸露状态，进而分别作为导电的触头使用。
进一步，感应线圈50的第一端51与正极导电片410连接、第二端与负极导电片420连接，则通过正极触头部分412和负极触头部分422即可为感应线圈50供电。具体在配合的实施中参见图3所示：
下壳体20内设置有沿长度方向延伸的两个导电弹针70，该导电弹针70是与电路24连接的；该导电弹针70至少部分裸露于腔室22内形成电接触的触头的，进而当筒状提取器30接收在腔室22内时，两个导电弹针70的顶端能与正极触头部分412和负极触头部分422分别弹性抵靠形成导电，进而使感应线圈50形成完整的通路。
进一步在优选的实施中，上壳体10和下壳体20上设置有磁吸、卡扣等连接结构或部件，进而当筒状提取器30接收在腔室22内时，能通过磁性吸附或卡扣等稳定保持导电弹针70于压缩的状态，一方面防止导电弹针70的弹力性将筒状提取器30弹出，另一方面防止导电弹针70的顶端与正极触头部分412和负极触头部分422接触不良。
在可选的实施中，由于感应线圈50外表面上通常包裹有绝缘层或喷涂有绝缘漆，通常感应线圈50可以分别将第一端51和第二端52分别与片状导电元件40的焊接的方式稳定连接。在图5所示的优选中，正极导电片410外表面对应靠近第一端51的部位设置有相对凸出的正极焊接点411，同样负极导电片420外表面上靠近第二端52的部位设置有相对凸出的负极焊接点421。
或者在其他的可选实施中，以上凸出的正极焊接点411或负极焊接点421可以采用螺纹孔的方式替代，对应在感应线圈50可以分别将第一端51和第二端52分别打孔，而后通过螺钉分别将第一端51和第二端52固定在以上螺纹孔上形成导电。
根据图5所示的优选实施，感应线圈50呈截面形状为方形的扁形线圈，在其他实施中还可以采用常用的截面形状为圆形的线圈。
配合图3所示的抽吸过程中的气流路径，图5所示的筒状提取器30的下端表面上设置有若干凸出的突起35。用于当筒状提取器30接收于腔室22内时该突起35与腔室22的底端内壁抵靠，进而使筒状提取器 30的下端表面与腔室22的底端内壁保持一定的间距而不能完全贴合，保证气流能沿图3中所示由筒状提取器30的下端表面与腔室22的底端内壁之间的间隙进入至孔眼33内。
进一步在以上的可选实施中，以上感应线圈50由于缠绕在筒状提取器30外壁上，则相比缠绕在形成腔室部件的外壁上具有更低的螺旋内径，进而产生的磁场可以更加集中。在优选的实施中，基于适配常用的直径5.6mm的可抽吸材料A、以0.5～1.5mm厚度的聚合物塑胶材质的筒状提取器30的尺寸，感应线圈50可以采用大约6.0～7.5mm的内直径，更加优选的采用6.5～6.8mm的内直径。绕成螺旋状的圆柱形感应线圈50的长度可以在大约8mm到大约14mm的范围内，感应线圈50的匝数大约8匝到15匝的范围内。相应地，内体积可能在大约0.15cm 3至大约1.10cm 3的范围内。
在更加优选的实施中，电路20供应到感应线圈50的交变电流的频率介于80KHz～400KHz；更具体地，所述频率可以在大约200KHz到300KHz的范围。
在一个优选的实施例中，电芯23提供的直流供电电压在约2.5V至约9.0V的范围内，电芯23可提供的直流电流的安培数在约2.5A至约20A的范围内。
在一个优选的实施例中，感受器60可以具有大约12毫米的长度，大约4毫米的宽度和大约0.5毫米的厚度，并且可以由等级430的不锈钢(SS430)制成。作为替代性实施例，感受器60可以具有大约12毫米的长度，大约5毫米的宽度和大约0.5毫米的厚度，并且可以由等级420的不锈钢(SS420)制成。在其他的变化实施例中，感受器60还可以被构造成圆筒状或管状的形状；在使用时其内部空间形成用于接收气溶胶生成制品A的腔室，并通过对气溶胶生成制品A的外周加热的方式，生成 供吸食的气溶胶。这些感受器还可以含有铁镍的合金材料(比如坡莫合金)制成。
在又一个可选的实施中，感受器60是由以上感受性的材质制备的，或者是由陶瓷等耐热的基体材质外表面上电镀、沉积等形成感受材料涂层获得的。
进一步图7示出了又一个实施例的结合于上壳体10上的提取组件的示意图，包括：
沿径向方向由内向外依次设置的筒状提取器30a、片状导电元件40、感应线圈50a；以及，
保护罩80a，在实施中采用刚性PC材质制备，将筒状提取器30a、片状导电元件40、感应线圈50a整体封装成一个组件模块，进而便于取用。
在该图7所示的变化实施中，可以将片状导电元件40的位置置于感应线圈50a外，即沿径向方向位于感应线圈50a与保护罩80a之间；并使片状导电元件40由保护罩80a内壁上设置的固定结构进行保持固定。同样，感应线圈50a的两端分别与对应的片状导电元件40焊接。
在又一个优选的实施中，提取组件还可以包括：
电磁屏蔽膜(图中未示出)，沿感应线圈50a的轴向延伸并围绕或包裹感应线圈50a，用于从外部对感应线圈50a的磁力线进行屏蔽或者扭曲，使感应线圈50a产生的磁场尽可能地都集中于内部。
在可选的实施中，电磁屏蔽膜是柔性的电磁屏蔽膜，比如可以是比较常用的由铁粉30％、镍粉5％、钴粉5％及有机柔性载体余量的粉体，加热熔化后采用制膜工艺制成的厚度为0.2毫米的膜材，其中金属粒子颗粒度小于100纳米并均匀分散在塑料材料中，即能实现磁场屏蔽的性能。或者在又一个可选的实施中，电磁屏蔽膜是在柔性基材比如PI膜、PEN 膜、PEI膜、PC膜、布、纸等上通过沉积、印刷或喷涂等方式在表面形成由镍、铬、铝、钛、锡、铟的合金涂层制成的电磁屏蔽膜。或者在又一个可选的实施中，电磁屏蔽膜是具较低厚度的高电导率、高磁导率的金属或合金的膜，例如Al膜、铜膜、钛膜或沉积高磁导率的磁性金属箔例如铁合金箔、钴合金箔、镍合金箔等。
本申请的又一个实施例还提出一种气雾生成装置，如图3所示，气流通道路径R2包括：
入口，是由上壳体10和下壳体20之间结合部位的间隙界定形成的，用于在抽吸的过程中供外部空气进入气雾生成装置；
第一部分R21，装配之后由上壳体10和下壳体20被上壳体10围绕部分的外壁之间界定的，并且成朝近端110的方向延伸；
第二部分R22，由筒状的提取器30与下壳体20形成腔室22的内壁之间界定的，并且是朝远端120方向延伸；
第三部分R23，抽吸过程中由形成腔室22的内壁靠近远端120的端部由孔眼33进入提取器30后朝近端110被抽吸而出。
在该实施例中，被磁场穿透发热的感受器60还可以采用电阻或红外等发热的方式替换。
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。
