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。
实施例一
本申请实施例提出的气雾生成装置，其构造参见图2所示，包括：
腔室，可抽吸材料A例如烟支可移除地接收在腔室内；
作为磁场发生器的电感线圈L，用于在交变电流下产生交变磁场；
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，在被交变磁场穿透下发热，进而对可抽吸材料A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；

电路20，通过电连接到可充电的电芯10，并将电芯10输出的直流，转变成具有适合频率的交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2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，并特别地半径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的匝数大约8匝到15匝的范围内。相应地，内体积可能在大约0.15cm3至大约1.10cm3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～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。
在优选的实施例中，图2中感受器30是由具有适当磁导性能的金属或合金材质制备，从而在使用时能相应磁场形成感应发热，进而加热接收的可抽吸材料A生成供吸食的气溶胶。这些感受器30可以由等级420的不锈钢(SS420)、以及含有铁镍的合金材料(比如J85/J66坡莫合金)制成。
在图2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和安装感受器30的管状支架40，该管状支架40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采用螺旋缠绕的方式布置在管状支架40的外壁上，并且管状支架40的至少一部分内部中空形成用于接收可抽吸材料A的腔室。
进一步参见图3和图4所示，对于感受器30的片状构造，具有第一端31和第二端32；其中，第一端31与用于接收可抽吸材料A的腔室的敞口相对，在使用中第一端31作为自由端被构造成尖端的形状进而便于插入至通过敞口端接收于腔室的可抽吸材料A中，第二端32作为安装和连接的端部用于通过管状支架40提供支撑使感受器30在装置内稳定保持和安装固定。
在更加优选的实施中，感受器30的构造是由沿厚度方向相对的第一片状体310、第二片状体320共同形成；具体，
第一片状体310包括有平直的第一部分311，由第一部分311沿厚度方向向外凸起形成的第二部分312，以及由第一部分311靠近第二端32的至少一部分朝宽度方向延伸出的第三部分313；
对应第二片状体320的形状与第一片状体310近似，同样也包括有平直的第四部分321，由第四部分321沿厚度方向向外凸起形成的第五部分322，以及由第四部分321靠近第二端32的至少一部分朝宽度方向延伸出的第六部分323；
第一片状体310和第二片状体320结合之后在它们之间形成用于容纳和封装温度传感器340的容纳腔330；具体容纳腔330是由第一片状体310的第二部分312形成的第一凹陷结构331、以及第二片状体320的第五部分322的第二凹陷结构332共同形成。
在装配中，温度传感器340的感测部分341被容纳和封装在容纳腔330内，并可以通过打胶等方式封装和固定。同时，温度传感器340的电连接部分342采用设计成细长的引脚的形式由容纳腔330内贯穿第二端32至感受器30外，进而便于与电路20连接，而后电路20可以通过电连接部分342接收感测部分341的感测信号。在使用中，温度传感器40被封装在大体是磁场屏蔽的容纳腔330内，且感测部分341与第一片状体310和/或第二片状体320紧密抵靠，进而在能稳定或准确检测感 受器30温度的同时避免磁场的干扰。
在可选的实施中，温度传感器340可以是通过监测电阻变化进而计算温度的热敏电阻式的温度传感器比如PT1000，或者是通过计算两端的热电动势计算温度的热电偶式的温度传感器。
基于大量生产和制备感受器30的立意，进一步在优选的实施中，第一片状体310的第二部分312和/或第二片状体320的第五部分322是通过在扁平片状的以上感受材料例如钣金件上通过冲压形成或者制备的。同时在稳定的接合中，第一片状体310和第二片状体320这两者可以是通过焊接如激光焊接等的方式，进而固定呈一体。
在图3和图4所示的优选实施中，容纳腔330是沿感受器30的轴向延伸的；实施中容纳腔330的横截面大致可以是菱形、圆形、方形等等的形状。
根据图4中所示，第二部分312具有靠近感受器30的第一端31的横截面积是逐渐减小的锥形部3121，比如是圆锥形、三角锥形等等，用于减小插入可抽吸材料A时的阻力。
在更加优选的实施中，第二部分312的锥形部3121、或结合对应相近构造的第五部分322可以使得形成的容纳腔330靠近第一端31的前端部分呈锥形的形状，在安装中温度传感器340的感测部分341抵靠在容纳腔330的呈锥形的前端部分上，则便于紧固和安装。
根据图中所示的优选的实施，感受器30由第二部分312和第五部分322组成的形成容纳腔330的部分，沿厚度方向的尺寸是大于其他部分的。同时，由第二部分312和第五部分322的形成的容纳腔330的厚度尺寸是沿宽度方向向内逐渐增大的，从而使感受器30由第二部分312和第五部分322形成的外表面是逐渐变化的。一方面增大与可抽吸材料A的接触的面积，提升热传递的效率；另一方面可以减小感受器30插入至可抽吸材料A时的阻力。
在图5或图6所示的又一种可变的实施中，感受器30a/30b的第二片状体320a/320b是平直的形状；而仅有第一片状体310a/310b上通过冲压等方式形成的沿厚度方向向外凸起的第二部分312a/312b，并由该 第二部分312a/312b与第二片状体320a/320b之间形成用于容纳或封装温度传感器的容纳腔330a/330b。
当然根据图5或图6所示的实施，第二部分312a/312b的横截面形状可以大致是厚度尺寸沿宽度方向向内逐渐增大的三角形或者是圆弧形形状。并且从图5和图6可以看出，第二部分312a/312b沿厚度方向的凸起尺寸大于第一部分311a/311b的厚度尺寸。
在图7所示的又一个变化的实施中，感受器30c的第一片状体310c的第三部分313c沿感受器30c的厚度具有更大于第一部分311c和第二部分312c的尺寸，从而在厚度方向上相对于其他部分是凸出的，从而便于在装置内的安装或保持。
实施例二
本申请进一步还提出一种制备实施例一中的感受器的方法，参见图8所示，方法步骤包括：
S10，提供沿厚度方向相对的第一片状体310和第二片状体320；
S20，使第一片状体310和第二片状体320之间形成沿长度方向延伸的容纳腔330；
S30，获取温度传感器340，并将温度传感器340容纳或封装于容纳腔330内。
实施例三
本申请还提供一种气雾生成装置，与实施例一所提供的气雾生成装置不同的是，请参阅图9，为了便于对第二端320的支撑和固定，感受器30靠近第二端320的至少一部分具有尺寸增大的基座部分33，例如基座部分33是沿宽度方向增大。
进一步参见图9，感受器30内部具有容纳或保持空间，用于容纳、封装或保持有沿长度方向延伸的温度传感器34，温度传感器34用于在工作中实施感测感受器30温度。在图9的优选实施中，温度传感器34的至少一部分是从第二端320延伸出来的，进而便于与电路20的连接。温度传感器34延伸或裸露在感受器30外的部分呈细长的电引脚的形式。
在可选的实施中，温度传感器34可以是通过监测电阻变化进而计算温度的热敏电阻式的温度传感器比如PT1000，或者是通过计算两端的热电动势计算温度的热电偶式的温度传感器。
具体在图10所示的优选实施中，片状的感受器30是由第一片状部分31和第二片状部分32沿厚度方向层叠形成的。
在图9所示的实施中，片状感受器30的外表面是平坦的。
本申请进一步还提出一种适合于大量制备以上感受器30的方法，具体包括如下步骤：
S10，获取用于制备感受器30a的片状感受基材100，并将片状感受基材100加工形成若干感受器前体30a，如图10所示；
在实施中，片状感受基材100材质即以上所描述的具有感受性的金属材料，例如0.5mm厚的NiFe合金软磁板材。加工形成感受器前体30a的方式可以包括化学蚀刻的方式，将多余的部分蚀刻去除之后，即形成感受器前体30a。
当然在图10所示的优选实施中，基于批量制备的便利性，加工获得的若干感受器前体30a是矩阵布置的。
感受器前体30a的具体结构进一步参见图11所示，包括在同一平面内的第一片状部分31和第二片状部分32。同时，第一片状部分31和第二片状部分32是相连的而非分离的。并且，第一片状部分31和第二片状部分32是具有对称性的，具体在图12中是沿中心轴线L左右对称。
进一步第一片状部分31上设置有容纳和保持的温度传感器34的第一容纳槽311，或者第二片状部分32上也设置有可容纳和保持的温度传感器34的第二容纳槽321。
S20，如图12所示，将温度传感器34置入第一片状部分31的第一容纳槽311内，将第二片状部分32沿着图中箭头R方向绕中心轴线L朝第一片状部分31翻折或者折叠，翻折之后将温度传感器34夹持或者固定在第一片状部分31和第二片状部分32之间，再将第一片状部分31和第二片状部分32通过激光焊接等方式使其稳定结合，即获得图3所示的感受器30。
在图11和图12所示的优选实施中，为了便于第二片状部分32朝第一片状部分31的翻折，感受器前体30a上设置有若干沿绕中心轴线L布置的凹痕或者凹槽35；具有凹痕或者凹槽35的感受器前体30a对翻折或者对折的操作过程是有利的。
图13示出了又一个变化实施的感受器前体30b的结构示意图，感受器前体30b包括沿长度方向相背的第一片状部分31b和第二片状部分32b。同时，感受器前体30b还包括沿长度方向位于第一片状部分31b和第二片状部分32b之间的凹痕35b，该凹痕35b是沿宽度方向延伸的。制备中，第一片状部分31b以凹痕35b为轴朝第二片状部分32b翻折或对折即可制备获得感受器。当然，第一片状部分31b上还设有容纳温度传感器34的第一容纳槽311b；和/或，第二片状部分32b上还设有第二容纳槽321b。

在又一个可选的实施中，第一容纳槽311/311b/311c和/或第二容纳槽321/321b/321c具有大约0.1mm左右的深度。
实施例四
本申请进一步还提出一种制备实施例三中的感受器的方法，方法包括如下步骤：
S100，获取感受材质的片状基材100a，并在片状基材100a表面覆盖蚀刻掩膜200a，如图15所示；
通常，片状基材100a来料为卷材，从卷材上裁成以上尺寸的板材具有一定的弯曲度；在使用前需要通过适当的压力(通常小于10MPa) 整型使其发生一定的塑性形变，进而从曲面状的金属卷材被整型成平面的片状基材100a；
根据图15所示，蚀刻掩膜200a在光化学蚀刻中常采用光绘的菲林(俗称胶片)；同时，蚀刻掩膜200a包括有与感受器形状相同的图案210a、以及非图案的空白区域220a；
S200，将覆盖有蚀刻掩膜200a的片状基材100a进行蚀刻；通常可以采用酸性的蚀刻液进行，例如含有氢氟酸的蚀刻液；
在蚀刻的过程中，片状基材100a被图案210a覆盖的部分不被腐蚀，而与空白区域220a相对的部分则被腐蚀去除；蚀刻完成之后片状基材100a上形成若干与图案210a相同的感受器；再由人工轻掰即可脱离，从而获得大量制备的感受器。
通常以长宽尺寸分别为250mm×120mm的片状基材100a作为材料制备时，一块片状基材100a可以同时刻蚀获得100-200个感受器。
采用蚀刻的方式制备感受器，相比机加工、冲压或激光切割的方式，蚀刻加工过程一方面不会产生加工应力，另一方面不会导致基材内部的晶相组织发生变化，使制备的感受器能保持与软磁材料相当的磁性能，进而在使用中发热效率高。
采用蚀刻的方式加工获得的感受器，获得的感受器边缘具有光滑的圆角，在保持表面美观的同时，光滑的边缘表面具有低的表面自由能，还有利于减少气雾产生制品的碎渣或冷凝液的粘附。
本申请的又一个优选的实施中，以上步骤的蚀刻过程是采用常规的光化学湿法蚀刻进行；细节步骤包括：
S110，通过光绘的方式按照所需制备的感受器的形状图案制备蚀刻掩膜200a即菲林(俗称胶片)；
S120，在片状基材100a上涂布感光油墨后，用30～40℃温度的热风预烘干10～15分，使感光油墨固化防止后续菲林显影中粘住菲林；
S130，将菲林贴附至涂布有感光油墨的片状基材100a上，进行曝光处理；曝光通常可以采用高压汞灯、碘镓灯、金属卤素灯照射，时间二十秒左右。
在曝光的过程中所涂布的感光油墨对应菲林图案210a的部分被感光，进而发生聚合交联反应形成固化的保护膜层；对应菲林的空白区域220a部分不会聚合交联形成固化；
S140，显影：去除菲林后，用显影液进行浸泡；具体采用1％碳酸钠水溶液或直接用清水于25～30℃浸泡片状基材100a；则未交联固化感光油墨被显影液溶化去除，则在片状基材100a表面对应图案210a部分形成保护膜层、对应菲林的空白区域220a的部分裸露出来；
S150，根据固化的效果显影后的片状基材100a还可以再次补光固化和干燥处理；其中，补光固化和干燥处理增加保护膜层与片状基材100a的结合力，提高耐蚀刻性能。如果采用的粘附力和固化能力较好感光油墨，则该步骤S150可以省略。
S210，将以上步骤制备获得的片状基材100a采用强酸蚀刻液进行刻蚀；蚀刻速度为0.04mm/分钟，蚀刻速度越快，侧蚀的程度就越小；
S220，步骤S210的蚀刻完成之后进行脱膜处理：采用20％氢氧化钠水溶液/50～60℃浸泡约十分钟，溶解保护膜层后清洗则获得若干矩阵排列的感受器，人工分离取样即可获得大量的感受器单体。
实施例五
本申请进一步还提出一种通过实施例四制备方法制备得到的感受器30d，如图16所示，感受器30d上带有缺口36d；后续通过激光焊接的方式，在缺口36d内壁上焊接不同材质的第一电偶丝和第二电偶丝，进而形成用于感测感受器30d温度的热电偶34d。
在一个可选的实施中，热电偶34d的第一电偶丝作正极采用镍铬合金丝，第二电偶丝作负极采用镍硅合金丝的K型热电偶。
在本申请实施例中，通过将温度传感器封装或容纳于感受器内，一方面可以基本隔离磁场对感测部的影响，另一方面可以将感受器与温度传感器集成为一体，提升安装的稳定和测温的准确性；同时便于整体更换和安装。
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。
