近端110设置有接收孔111，可抽吸材料A可通过该接收孔111接收于壳体10内被加热或从壳体10内移出；
远端120设置有进气孔121和充电接口122；进气孔121用于在抽吸的过程中供外部空气进入至壳体10内；充电接口122例如USB type-C接口、Pin针式接口等，通过与外部电源或适配器连接之后，用于为气雾生成装置进行充电。
进一步壳体10内部的构造参见图3和图4所示，包括沿宽度方向依次设置的第一隔室130和第二隔室140；其中，第一隔室130用于安装电芯和电路板等(图中未示出)电子器件的安装空间，而第二隔室140是用于安装并保持加热机构的安装空间。
进一步参见图4和图5所示，沿壳体10的长度方向设置于第二隔室140内的红外发射器30，其立体构造可以参见6所示；红外发射器30包括：
管状基体31，该管状基体31作为刚性载体以及容纳可抽吸材料A的物件，在实施中可以采用由石英玻璃、陶瓷或云母等耐高温且透红外 的材料制成；优选是透明的材质，比如采用红外线透过率在95％以上的耐高温材料；该管状基体31的内部空间形成用于容纳并加热可抽吸材料A的腔室32；
形成于管状基体31的至少一部分外表面的红外发射涂层33，该红外发射涂层33是电致的红外发射涂层，可在通电情况下能够自身发热并向接收于腔室32内的可抽吸材料辐射具有可用于加热可抽吸材料A的红外线，例如以上的3μm～15μm的远红外线。当红外线的波长与可抽吸材料A的挥发性成分吸收波长匹配时，红外线的能量易于被可抽吸材料A吸收。
通常实施中红外发射涂层33可以是包括陶瓷系材质比如锆、或者Fe-Mn-Cu系、钨系、或者过度金属及它们的氧化物材质制备的涂层。
在优选的实施中，红外发射涂层33是优选由Mg、Al、Ti、Zr、Mn、Fe、Co、Ni、Cu、Cr等至少一种金属元素的氧化物组成，这些金属氧化物在被加热到适当的温度时即会辐射以上具有加热效用的远红外线；厚度优选可以控制30μm～50μm；形成于基体31表面的方式可以将以上金属元素的氧化物通过大气等离子喷涂的方式喷涂在基体31外表面后固化即得；
在其他的变体实施中，红外发射涂层33还可以是形成于基体31内表面的。
红外发射器30还包括分别形成于红外发射涂层33的相对两端的至少一部分外表面的第一导电涂层34和第二导电涂层35；其中，根据图7所示的优选实施，第一导电涂层34和第二导电涂层35均是环形的形状并与红外发射涂层33接触的，在使用中可以分别被电连接至电源的正极和负极，从而使红外发射涂层33电致发热并辐射红外线。第一导电涂层34和第二导电涂层35可以为是通过浸渍或涂布等方式形成的导电涂层，通常可以是包括银、金、钯、铂、铜、镍、钼、钨、铌或它们的金属或合金。
进一步参见图4和图5，加热机构还包括沿径向方向位于红外发射器30外的绝热件40，该绝热件40呈管状形状，并包括沿径向方向由内向外依次设置的内管壁43和外管壁41，以及位于内管壁43和外管壁41之间的中心区域42；在实施中，内管壁43和外管壁41可以采用刚性材质制备例如不锈钢、陶瓷、PPEK等，而中心区域42的压力被构造为低于绝热件40外部的压力，即具有或形成一定的真空度，以减少红外发射器30在工作中产生的热量沿径向向外的传导
进一步参见图4所示的实施例，在实施中第二隔室140内还设有沿 长度方向位于加热机构与进气孔122之前的管状元件20，该管状元件20用于在抽吸的过程中使腔室32和进气孔122进行气流连通；参见图4中箭头R所示，在抽吸的过程中，外部空气通过进气孔122进入壳体10内，并经管状元件20的内部中空21进入至腔室32后，通过可抽吸材料A被用户吸食。
同时进一步参见图4所示，以上管状元件20内部中空21的内径并非是恒定的，而是具有是沿进气孔122向腔室32的方向逐渐减小的部分211。
进一步参见图4至图6所示，为了保证红外发射器30和绝热件40在壳体10内的稳定固定，以及对可抽吸材料A提供支撑，以使可抽吸材料A在腔室32内是固定保持的；壳体10内还设有上固定座60和下固定座50；上固定座60和下固定座50均大致呈具有中空的环形形状设计。
下固定座50的下表面设置有插接凹槽51，并通过使管状元件20的上端插接在该插接凹槽51内，从而使下固定座50自身被稳定支撑和保持在壳体10内；同时为了保证与管状元件20插接之后的气密性和结合的稳定性，在插接凹槽51与管状元件20接合的部位设置有硅胶密封圈22。
进一步从图4至图6所示中，插接凹槽51是与下固定座50的中空同轴的柱状空间，并且直径大于下固定座50的中孔55的直径尺寸，从而使得管状元件20的上端抵接在插接凹槽51内。
同时下固定座50上还设置有分别用于供红外发射器30、绝热件40、以及可抽吸材料A抵靠的第一保持部52、第二保持部53和第四保持部54，用于对红外发射器30、绝热件40、以及可抽吸材料A提供支撑，从而使它们稳定保持在壳体10内。
从以上还可以看出，以上第四保持部54是呈突入至腔室32内的凸环形状，用于形成腔室32内径减小的部分，从而使可抽吸材料A抵靠在该第四保持部54上形成止动。
而对应相应的上固定座60用于对对红外发射器30和绝热件40的上端提供支撑，对它们的上端进行稳定固定。
进一步参见图4至图8所示，装置还包括有设置红外发射器30的腔室32内的温度传感器80，该温度传感器80被固定于一个销钉或刀片形的支架70的尖端，从而当可抽吸材料A接收于腔室32内时，销钉或刀片形的支架70以及温度传感器80可插入至可抽吸材料A内部，进而使温度传感器80能感测可抽吸材料A的温度，进而便于后续根据感测 的可抽吸材料A的温度调整红外发射器30的功率使抽吸过程的温度保持在预设的最适温度。
根据图6至图8所示的优选实施中，该支架70表面靠近下端的位置还设置有若干沿径向延伸出的支撑片71，并通过该支撑片71沿径向方向抵靠于下固定座50的中孔55的内表面上，当然更进一步是过盈或者紧配的，从而使支架70在下固定座50内是稳定保持的。
同时，进一步参见图6至图8所示，相邻支撑片71之间是具有间距进而由这些间距形成的供气流穿过的通道72的，进而可以使得管状元件20内的空气能通过这些通道72进入至腔室32内，具体参见图6和图8的箭头R所示。
在又一个可选的实施中，参见图9和图10所示，可以通过订制的方式生产的刚性热电偶式的温度传感器80a自身呈销钉或刀片的形状，其自身可以便于插入至可抽吸材料A内并检测可抽吸材料A的温度。当然，为了便于这一种可订制生产的温度传感器80a的电连接和固定，可以通过一支撑座82a对其进行固定，使其能稳定保持；并且其自身还具有细长的导电引脚81a，使其便于进行电连接。
或者在又一个可选的实施中，对于检测可抽吸材料A的温度传感器80b可以采用图11所示的构造，包括：
呈销钉或刀片状的刚性衬底81b，用于插入至可抽吸材料A内；
形成于该刚性衬底81b表面的导电轨迹82b，该导电轨迹82b是采用正向或者负向电阻温度系数的材质制备，从而当刚性衬底81b插入至可抽吸材料A内时，该导电轨迹82b是与可抽吸材料A导热接触的，进而可以通过接收可抽吸材料A的热量进而保持温度一致，而后再通过引脚83b检测导电轨迹82b的电阻值，即可通过该电阻值82b确定导电轨迹82b和可抽吸材料A的温度。
以上是采用红外发射器30/30a通过辐射红外线的方式加热可抽吸材料A，在其他的变体实施中或者可以采用与以上红外发射器30/30a具有相近的管状形状的电阻加热器或者管状的电磁感应式的加热器对可抽吸材料A进行加热。
采用以上气雾生成装置，通过将温度传感器80/80a/80b设置于腔室内，并可以插入至可抽吸材料A内直接检测可抽吸材料A的温度，进而便于在加热过程中的温度控制，对抽吸过程中的温度监测更加准确。
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。
