实施例一
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，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。
根据产品使用中的设置，电感线圈L可以包括绕成螺旋状的圆柱形电感器线圈，如图1中所示。绕成螺旋状的圆柱形电感线圈L可以具有范围在大约5mm到大约10mm内的半径r，优选地，半径r可以大约为7mm。绕成螺旋状的圆柱形电感线圈L的长度可以在大约8mm到大约14mm的范围内，电感线圈L的匝数在大约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供应到电感线圈L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10提供的直流供电电压在约2.5V至约9.0V的范围内，电芯10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30可以具有大约12毫米的长度， 大约4毫米的宽度和大约50微米的厚度，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30可以具有大约12毫米的长度，大约5毫米的宽度和大约50微米的厚度，并且可以由等级430的不锈钢(SS430)制成。在又一个优选的实施例中，感受器30还可以被构造成圆筒状的形状；在使用时其内部空间用于接收可抽吸材料A，并通过对可抽吸材料A的外周加热的方式，生成供吸食的气溶胶。这些感受器还可以由等级420的不锈钢(SS420)、以及含有铁镍的合金材料(比如1J85坡莫合金)制成。
在图1所示的实施例中，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，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。
在一个优选的实施方式中，为了能准确监测对可抽吸材料A的加热温度、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；在图2至图4所示的又一个实施例中感受器30a的构造，包括：
由第一部分31a和第二部分32a构成的感受部分，大体呈销钉状在使用中插入至可抽吸材料A内部进行加热；
第一金属材料33a和第二金属材料34a，分别连接在感受部分的不同位置上，并且第一金属材料33a和第二金属材料34a采用不同的电偶材质制备，进而在第一金属材料33a和第二金属材料34a之间形成可用于检测感受器30a温度的热电偶。
具体地，在实施过程中，第一金属材料33a和第二金属材料34a被构造成细长的丝状或引脚的形式，并可通过焊接等的方式固定连接在感受部分上；当感受部分在变化的磁场穿透下发热时，通过第一金属材料33a和第二金属材料34a的自由端耦合接入电路20，则可以检测由感受 器30a的温度变化引起的电动势的变化进而确定感受器30a的温度。
在一个可选的实施中，第一金属材料33a可以采用镍、镍铬合金、镍硅合金、镍铬-考铜、康青铜、铁铬合金中的一种；第二金属材料34a则可以采用以上材料中与第一金属材料33a不同的另一种进行。
在实施过程中，以上第一金属材料33a和第二金属材料34a是与变化的磁场隔离的，以阻止第一金属材料33a和第二金属材料34a自身被磁场加热到与感受部分相当的温度，从而影响测温功能的实现。
进一步地，根据图3至图4所示的示例，为了感受器30a的生产和装配的便利性；在实施过程中，感受部分分为可独立拆卸和装配的第一部分31a和第二部分32a。
在一个可选的实施中，图3至图4中第一部分31a和第二部分32a都是采用适合的金属或合金的感受材料制备的。
在又一个可选的实施中，第一部分31a和第二部分32a是采用在刚性基材比如陶瓷、耐温塑胶等表面上通过喷涂、印刷、沉积金属或合金的感受材料涂层制备的。
进一步根据图3至图4所示，其中，
第二部分32a被构造成中空的筒状或者管状的形状；
第一部分31a包括：
针头部311a，该针头部311a的至少一部分的外径逐渐减小形成锥形尖端，该锥形尖端使感受部分能顺畅地插入至可抽吸材料A内；
连接部312a，由针头部311a朝第二部分32a延伸形成，连接部312a呈外径尺寸比针头部311a的最大外径小的柱状的形状，并且连接部312a的外径是与第二部分32a的内径是适配的；从而在安装中连接部312a伸入至第二部分32a内并通过过盈或紧配等方式使第一部分31a紧固地在第二部分32a的端部处连接；
以及，从连接部312a延伸出的延长部313a，该延长部313a被构造成弧形；该延长部313用于焊接上述第一金属材料33a和第二金属材料34a。
同时，在图3所示的优选实施例中，第一金属材料33a和第二金属材料34a是分别连接在延长部313a靠近两侧的部位。
在组装后的图4所示的优选的实施例中，第一金属材料33a和第二金属材料34a被构造成穿过第二部分32a的内腔后至少部分裸露出来，进而可以便于与电路20耦合。并且，在实施中第一金属材料33a和第二金属材料34a均是位于管状第二部分32a内部磁场屏蔽区域内的，进而在使用中第一金属材料33a和第二金属材料34a自身是不发热的，避免使第一金属材料33a和第二金属材料34a暴露在磁场中感应发热而影响检测信号。
在图3所示的优选实施中，延长部313a的延伸长度L大致长度在5mm左右，延长部313a是位于管状形状的第二部分32a内腔之中形成的磁场屏蔽区域之中的。并且延长部313a与第二部分32a的内壁是抵靠和紧密贴合的，从而延长部313a能够接收第二部分32a的热量，则通过第一金属材料33a和第二金属材料34a检测的温度大体是第一部分31a和第二部分32a的平均温度。
根据图4所示的优选实施例，第一金属材料33a和第二金属材料34a与延长部313a连接的位置沿第二部分32a的长度方向与第二部分32a的上端的距离d的尺寸大约是第二部分32a的长度的三分之一到二分之一之间；这一部位基本是第二部分32a在磁场中发热温度较为集中的区域；进而使第一金属材料33a和第二金属材料34a对应在该部位连接时感测的感受器30a的温度变化的结果是较为准确的。
基于图4所示的优选实施，延长部313a的形状是非筒状的构造，而 被被构造成弧片状；具体，在图4中延长部313a沿第二部分32a的圆周方向的弧度小于π，则延长部313a具有足够大的用于通过焊接等方式连接第一金属材料33a和第二金属材料34a的开口。
进一步在实施中，为了防止金属材质的第二部分32a对检测产生干扰，第一金属材料33a和第二金属材料34a表面通过沉积、电镀、喷涂、表面氧化等方式形成包裹第一金属材料33a和第二金属材料34a的绝缘层，进而与第二部分32a以及感受器30a的其他部分绝缘。
或者，在图5所示的又一个可选的实施中，感受器30b的第一金属材料33b通过焊接等方式与第二部分32b连接，而第二金属材料34b与第一部分31b的延长部313b连接，进而第一金属材料33b和第二金属材料34b之间形成用于感测感受器30b温度的热电偶。
或者，在其他的可选的实施中，第一金属材料33b和第二金属材料34b是通过焊接等方式连接在感受器30b的同一个位点或者同一部位的。
在图6所示的又一个可选的实施中，感受器30c还可以具有设置于第二部分32c的端部的基座部分35c，在使用中可通过管状支架50或其他部件对基座部分35c提供支撑进而使感受器30c稳定保持在气雾生成装置内。
而第一金属材料33c和第二金属材料34c由第二部分32c内贯穿至基座部分35c外，进而便于与电路30连接。
或者，在不同于图6所示的又一个变化实施中，第一金属材料33c和第二金属材料34c裸露于基座部分35c外的部分被构造成形成于基座部分35c上的电触头或者端子的形态，进而电路20可以通过适配的电端子或导电弹针与第一金属材料33c和第二金属材料34c连接。
同时，基座部分35c采用隔热的PEEK材质、或者导热系数较低的氧化锆陶瓷等材质制备，可以有效阻止感受器30c的热量传递至管状支 架50或其他部件上。
以上气雾生成装置感受器，在感受器上通过焊接等方式设置具有不同材质的电偶材料，进而形成可用于通过热电势检测感受器温度的热电偶，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。

如图1，气溶胶生成装置包括壳体组件10、腔室1001和发热组件30，所述腔室1001设于所述壳体组件10内，所述发热组件30定位于所述腔室1001内以用来加热气溶胶形成基质。气溶胶生成装置还可以包括电路板20和控制器(未画出)。所述电路板20与控制器连接。气溶胶生成装置还可以包括电池组件10，所述电路板20和控制器都与所述电池组件10电连接。
如图7到图9，发热组件30包括具有第一端105和第二端106且延伸于该第一端105和第二端106之间的发热体1和温度传感单元2，所述发热体1配置为加热气溶胶形成基质以生成气溶胶。所述发热体1内部设有至少一个大致沿着所述发热体1的长度方向延伸的容置通道4(比如容置通道4可以是倾斜的，沿着所述发热体1的长度方向延伸)，至少一个所述容置通道4所形成的中空部分的体积小于所述发热体1体积 的25％(计算发热体1的体积时，未减去容置通道4的体积)；温度传感单元，收容于所述容置通道内。
相同材质(比热容相同)的发热体1，储热能力与实体的体积成正比，容置通道4设置的越大，发热体1的实体体积就越小，储热能力就越差。在气溶胶生成设备使用的过程中，冷空气先经过发热体1的一端(第一端)，然后经过发热体1的另一端(第二端)，而冷空气在从发热体1的第一端到第二端的过程中，会不断的吸收发热体1的热量，因为在第一端的时候，空气和发热体1的第一端温差大，吸收的热量多，而空气在第二端的时候，因为空气在流动的过程中已经吸收了大量的热量，空气温度高，空气吸收第二端的热量少。空气在流动的过程中，吸收第一端和第二端的热量不同，现有加热体因为容置通道大，实体体积小，储能差，在第一端损失的热量比第二端多时，就会导致第一端温度低，而第二端温度高，整个发热体1温度不均匀。而本申请因为控制容置通道4的体积占所述发热体1体积的25％以内，发热体1实体体积大，有很好的储热能力，在第一端损失的热量比第二端多时，第一端的温度不会有太大波动，从而第一端的温度和第二端的温度比较接近，整个发热针温度更加均匀。
所述温度传感单元2包括第一热电偶丝203和第二热电偶丝204，所述第一热电偶丝203和第二热电偶丝204至少部分设于所述容置通道内。
如下所述的容置通道至少有两种设置方式，此处只是列举，并不限制只有这两种：
第一种(图7和图8)：所述容置通道4包括两个孔，所述第一热电偶203和第二热电偶丝204分别设于一个孔内。所述发热体1的长度为10～70mm(发热体1的尖端107大致为圆锥形，且长度为2mm)， 优选的所述发热体1的长度为10～25mm，所述发热体1的直径为2～2.6mm，所述孔的直径为0.5～0.7mm。优选的，所述发热体1的长度为20mm,所述发热体1的直径为2.3mm，所述孔的直径为0.55mm。
第二种(图9)：所述容置通道4包括一个孔，所述第一热电偶203和第二热电偶丝204同时设于一个孔内。
所述容置通道4始于所述发热体的第一端105大致朝向第二端延106伸且止于一封闭端，所述封闭端位于所述第一端105与第二端106之间。所述容置通道4的延伸长度为所述发热体的延伸长度的30％～80％。优选的，所述容置通道的延伸长度为所述发热体的延伸长度的50％～70％。
当所述发热体的长度为20mm时，所述发热体1的直径为2mm，所述容置通道4包括两个孔，且孔的直径为0.7mm，孔的深度为14.4mm时，所述容置通道所形成的中空部分的体积为所述发热体体积的18.9％。
当所述发热体的长度为20mm时，所述发热体1的直径为2.3mm，所述容置通道4包括两个孔，且孔的直径为0.55mm，孔的深度为12mm时，所述容置通道所形成的中空部分的体积为所述发热体体积的7.4％。
当所述发热体的长度为10mm时，所述发热体1的直径为2.6mm，所述容置通道4包括两个孔，且孔的直径为0.5mm，孔的深度为3.4mm时，所述容置通道所形成的中空部分的体积为所述发热体体积的2.9％。
优选的，所述容置通道所形成的中空部分的体积为所述发热体体积的20％以内。
所述发热体1在长度方向上分为第一发热段101和第二发热段102(如图10)。
所述第一发热段101沿长度方向设置有通孔以形成所述容置通道4(如图8、9、10)。所述第一热电偶丝203和第二热电偶丝204均包括 连接部201和延伸部202，所述延伸部202至少部分设于所述容置通道4内；所述连接部201紧邻所述第一发热段101和第二发热段102的连接位置进行固定。具体的，所述发热体1设有凹槽5，所述延伸部202固定于所述凹槽5内，所述容置通道4与所述凹槽5连通。
所述凹槽5的设置方式至少三种，此处只是列举，并不限制只有如下所述的三种：
第一种(图10)：所述凹槽5设于所述第一发热段101，且位于所述第一发热段101和第二发热段102连接的端面。
第二种(图9)：所述凹槽5设于所述第二发热段102，且位于所述第二发热段102和所述第一发热段101连接的端面。
第三种：所述第一发热段101和第二发热段102都设有所述凹槽5，所述凹槽5设于第一发热段101与第二发热段102连接的端面。
现有技术都是在发热体1内部开盲孔，然后将温度传感单元2插入到盲孔内，温度传感单元2和发热体1不固定，从而导致温度传感单元2和发热体1接触不稳定，测量的温度不精确，而本申请将连接部201与发热体1固定连接，温度传感单元2和发热体1的接触稳定可靠，测量的温度更加准确。
所述连接部201固定于所述凹槽5中时，所述连接部20低于或平齐所述凹槽5所在的端面，方便所述第一发热段101和第二发热段102连接。当所述连接部201固定于所述凹槽5中时，所述凹槽5中可能还有空隙，此时用填充体3将所述凹槽5填平(图11)，避免所述第一发热段101和第二发热段102连接后，所述凹槽5中有空隙，一方面，影响发热体1的实体体积，从而影响发热体1的储热能力；另一方面，间隙部分依靠空气导热，传热慢，而在间隙中填充所述填充体3，填充体3的导热快，从而让发热体1发热更加均匀。所述填充体3可以是焊接 在凹槽5中的镍。
所述发热体1至少有两种，此处只是列举，并不限制只有如下所述的两种：
第一种(如图1)：所述发热体1为电磁式发热体，即气溶胶生成装置还包括电感线圈L，用于在交变电流下产生变化磁场；所述发热体1与所述电感线圈L耦合，从而使所述第一发热段101和第二发热段102在被变化磁场穿透下发热，进而对气溶胶形成基质40进行加热，生成气溶胶。根据产品使用中的设置，电感线圈L可以包括绕成螺旋状的圆柱形电感器线圈，如图1中所示。绕成螺旋状的圆柱形电感线圈L可以具有范围在大约5mm到大约10mm内的半径r，优选地，半径r可以大约为7mm。电感线圈L的匝数大约8匝到15匝的范围内。电路20供应到电感线圈L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。电池组件10提供的直流供电电压在约2.5V至约9.0V的范围内，电池组件10可提供的直流电流的安培数在约2.5A至约20A的范围内。
第二种(图8和12)：所述发热体1为印刷电路式，即所述第一发热段101和第二发热段102包括基体103和印刷电路104，所述印刷电路104设于所述基体103上。所述基体103可以由导体或者非导体(如陶瓷或者玻璃)制成，如果所述基体103由导体制成，在印制所述印刷电路104前，需要先在所述基体103表面弄一层绝缘层，然后再印制所述印刷电路104。为了方便印制所述印刷电路104，可以先将所述第一发热段101和第二发热段102固定连接好，然后再印制所述印刷电路104。
所述第一发热段101和第二发热段102都发热，相比只所述第一发热段101发热，所述第二发热段102不发热，所述连接部201固定在所 述第一发热段101和第二发热段102连接的端面上，所述温度传感单元2检测到的温度更加准确。
发热组件还包括基座6，所述基座6设于第一发热段101远离第二发热段102的一端，所述基座6的设置方便将所述发热体1固定在气溶胶生成设备内。
所述第一发热段101和第二发热段102相互靠近的一端在加工时有倒角，所述第一发热段101和第二发热段102在固定连接后会留有一圈连接槽(图中未画出)，为了避免连接槽藏污纳垢，可以用镍丝填充连接槽，保持发热体1外表面光滑。
为了研究容置通道4的体积占所述发热体1体积的大小，对发热体1的影响，申请人做了如下一组实验：
样品A：所述发热体1的直径为2.3mm，第一发热段101长12.3mm且实心，第二发热段102长6mm，两个通孔构成容置通道4，通孔直径0.55mm，容置通道4的体积为发热体1体积的8.3％(计算发热体1的体积时，未减去容置通道4的体积)，第一发热段101靠近所述第二发热段102的一端设有凹槽5，凹槽5宽度和深度都是0.4mm，将两端拔掉绝缘层的第一热电偶丝203和第二热电偶丝204分别穿过两个通孔，然后焊接在凹槽5内，然后焊接第一发热段101和第二发热段102。在发热体1的外表面，从第二发热段102远离第一发热段101的一端开始，在长度方向上，每间隔2mm焊接一个热电偶，共焊接5个热电偶(第一个热电偶焊接在距离端面3mm处)。
样品B：样品B和样品A其他设置相同，不同点在于一个通孔构成容置通道4，通孔直径为1.6mm(容置通道4的体积占发热体1体积的35％)。
将样品A和样品B放于交变的磁场中，样品A和样品B发热，分 别记录样品A和样品B的5个热电偶检测到的温度，样品A记录的温度如图14，样品B记录的温度如图15，从如图14可以看出，记录5个热电偶检测到的温度线条十分靠近，甚至重叠，五个检测点的温差在10摄氏度以内，发热体1整体发热均匀；而如图15中，记录5个热电偶检测到的温度线条间隔大，5个热电偶检测到的温度差在40摄氏度左右，发热体1各段温差大。综上，控制容置通道4的体积占发热体1体积比例的大小，能有效的提升发热体1发热的均匀度。
