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。
本申请一实施例提出一种气雾生成装置，其构造可以参见图1所示，其用于接收可抽吸材料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10，整体形状大致呈方形形状，即沿长度方向的尺寸大于宽度方向的尺寸、沿宽度方向的尺寸大于厚度方向的尺寸；其中，壳体10包括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可抽吸材料A的抽吸和操作的端部。
进一步近端110上设置有第一开口111，在使用中可抽吸材料A可通过该第一开口111接收于壳体10内被加热或从壳体内移除。
远端120上设置有与第一开口111相对的第二开口121，该第二开口121一方面用于抽吸过程中外部空气进入的进气口，同时还可以作为通过细棍、铁丝等清洁工具伸入至壳体10内对内部进行清洁的清洁口。
进一步，壳体10内在第一开口111和第二开口121之间形成有用于接收可抽吸材料A的腔室。壳体10内还设有：
用于供电的电芯20；
加热器30，被构造成围绕腔室的至少一部分的管状形状；在图1所示的优选的实施例中，加热器30是通过被变化的磁场穿透而发热进而加热可抽吸材料A的感受加热器。
在图1的实施中，壳体10内还设有：
第一感应线圈41，围绕加热器30沿长度方向的靠近近端110的第一加热区段31；第二感应线圈42，围绕加热器30沿长度方向的靠近远端120的第二加热区段32。进而在使用中，可以通过独立地启动第一感应线圈41使第一加热区段31发热，以加热被第一加热区段31围绕的可抽吸材料A的部分；或者可以独立地启动第二感应线圈42使第二加热区段32发热，以加热被第二加热区段32围绕的可抽吸材料A的部分。
进一步参见图1所示的优选实施，在第二开口121与加热器30之间还设置有中空管50；该中空管50用于对加热器30靠近远端120的端部提供支撑，并提供抽吸时外部空气由第二开口121进入可抽吸材料A 的气流路径。
同时，在抽吸的过程中气流如图1中箭头R所示，由第二开口121进入后经中空管50流向接收于加热器30的可抽吸材料A内，而后贯穿可抽吸材料A并携带生成的气溶胶至近端110的吸嘴端被抽吸。
进一步参见图1和图3，在本申请的优选实施中，加热器30沿长度方向具有靠近近端110的上端310、以及靠近远端120的下端320。并且加热器30靠近下端320的至少一部分呈向内收缩的形状，进而安装后形成使腔室内径减小的部位，该部位用于使可抽吸材料A接收至腔室内的前端A1是抵靠在该加热器30的收缩部位形成止动的。
进而由前端A1掉出的碎渣或者在靠近前端A1的部分与加热器30之间的冷凝液会至少先掉落在加热器30的收缩部位上被承接并重新汽化，减少了直接掉出或渗出产生的污染。
进一步，加热器30靠近下端320的至少一部分呈插入至中空管50内、或者是被中空管50围绕布置的。防止采用将中空管50伸入至加热器30的方式，加热器30内壁上的气溶胶冷凝液或碎渣直接顺着中空管50中空和内壁掉出的问题。
参见图1和图2所示，中空管50的构造包括：
靠近第二开口121的第一部分51；
靠近并围绕加热器30的第二部分53，当然根据图2第二部分53的内径是大于第一部分51的；
第三部分52，位于第一部分51和第二部分53之间，被构造成是内径逐渐减小的设计使其内壁呈倾斜，用于供加热器30的下端320抵靠；
同时为了便于中空管50自身在壳体10内的固定和保持，其上还设置有沿径向方向向外延伸的延长部分54。延长部分54可以抵靠在壳体10上设置的一些支撑的壁上，从而使中空管50自身稳定安装。
进一步参见图3所示，加热器30的上端310被构造成直径逐渐增大的广口，可以便于可抽吸材料A插入至加热器30内时提供倾斜引导。并且在图3中上端310的广口设计，使上端310的壁的外径相对是大于其他部位的；进而可以在上端设置支撑的支架等部件或结构对加热器30 的上端310进行支撑。如果该支架等部件或结构是至少部分围绕加热器30的环形形状，则可以在支架与加热器30之间留有一定的间隙形成空气层隔热。
图4和图5提供了又一个实施例的加热器30a，加热器30沿长度方向具有靠近近端110的上端310a、以及靠近远端120的下端320a。加热器30a的管壁靠近下端320a的至少一部分上设置有一个或多个凹槽321a。
在优选的实施中，凹槽321a是将金属感受材料的加热器30a通过冲压、按压等方式形成的。在图4和图5中，该凹槽321a是沿加热器30a的长度方向延伸的。
该凹槽321a使加热器30a靠近下端320a的部分内壁呈凸出的形态，使腔室内径减小。当可抽吸材料A接收在加热器30a内时，前端A1抵靠在该凹槽321a上形成止动。
图6示出了配合加热器30a的中空管50a的结构示意图；中空管50的构造包括靠近第二开口121的第一部分51a与靠近并围绕加热器30的第二部分53a。中空管50a用于围绕或者供加热器30a插入的第二部分53a的内壁上设置有一个或多个凸棱531a；该凸棱531用于当加热器30a下端320a的一部分插入时凸入或伸入凹槽321a中，进而阻止加热器30a绕中心轴线转动，防止连接在其上的热电偶丝、或者导线等器件扯断。
图7示出了又一个优选实施的加热器30b的结构，该加热器30b包括靠近上端310b的第一加热区段31b、靠近下端320b的第二加热区段32b；在使用中第一加热区段31b和第二加热区段32b可以独立地和/或依序地启动，进而独立地和/或依序地加热容纳于加热器30b的可抽吸材料A的不同部分。
以及位于第一加热区段31b和第二加热区段32b之间的第三区段33b，安装后该第三区段33b是避开第一感应线圈41和第二感应线圈42的。因而，第三区段33b所处位置的磁场强度是相比第一加热区段31b和第二加热区段32b低的，可以通过接收第一加热区段31b和第二加热 区段32b传递的热量加热处于该部位的可抽吸材料A的部分。
第一加热区段31b外壁上连接有第一金属材料61b；
第二加热区段32b外壁上连接有第二金属材料62b；
以及第三金属材料63b；在实施中，第一金属材料61b、第二金属材料62b和第三金属材料63b各自可以采用电偶材质例如铁、镍铬合金、镍硅合金、镍铬-考铜、康青铜、铁铬合金中的一种。
进一步在实施中，使第一金属材料61b和第三金属材料63b采用不同的材质，进而可以通过在第一金属材料61b和第三金属材料63b之间形成能感测第一加热区段31b温度的热电偶。
同理，使第二金属材料62b和第三金属材料63b采用不同的材质，进而可以通过在第二金属材料62b和第三金属材料63b之间形成能感测第二加热区段32b温度的热电偶。
基于只需组成热电偶两端是不同材质，则以上第一金属材料61b和第二金属材料62b可以是相同的。
同时，第三金属材料63b与加热器30b连接的部位可以是不做限制的，比如可以在加热器30b的任意位置。在图7的优选实施中，第三金属材料63b是焊接在第三加热区段33b外壁上的。
在图7所示的优选实施中，第一金属材料61b、第二金属材料62b以及第三金属材料63b被构造成细长的电引脚的形式，并可通过焊接等的方式固定连接在加热器30a对应的部位上。
例如在实施中，将第三金属材料63b作为热电偶的正极采用镍铬合金材质，第一金属材料61b和第二金属材料62b作为热电偶的负极均采用镍硅合金材质；进而使第一金属材料61b和第三金属材料63b之间形成K型热电偶感测第一加热区段31b的温度，以及在第一金属材料61b和第二金属材料62b之间形成K型热电偶感测第二加热区段32b的温度。
在其他的变化实施中，以上加热器30/30a/30b可以是电阻加热器或者是红外发射器。其中，电阻加热器可以是通过在管状的电绝缘衬底例如陶瓷管、PI(聚酰亚胺)膜等上形成导电轨迹后获得。
红外发射器可以是通过在管状的透红外基体例如石英管上沉积红 外发射涂层、或者是包裹红外发射薄膜后获得的，能通过辐射红外线的方式加热容纳在其内的可抽吸材料A。
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。
