金属本体31，用于在变化的磁场穿透下发热，进而加热可抽吸材料；在优选的实施例中，金属本体31采用不锈铁、镍钢、坡莫合金等包括铁或镍等磁导性能优良的合金材料；
保护层32，形成于金属本体31的表面，具有低的表面自由能。在一些实施例中，保护层32是准晶合金材料的保护层32，准晶合金是由金属制成的介于晶体和非晶体之间固相材料；
具体的，在材料学领域上晶体材料的结构具有长程有序性，结构单元按周期性进行排列，因而表现出较强的对称性。在任意两个晶胞的对应点，围绕一个通过晶格格点的旋转轴，旋转2π/n(n＝1,2,3,4,5,6)或其整数倍时，总可以找到与自身重合的点阵，这一性质称为晶体的取向对称性。根据晶体学基本定律，晶体的取向对称性受周期性的限制，只有固定的几种，即取向对称性只能取n＝1,2,3,4,6五种，而不能取n＝5或n>6的取向对称性。当然，非晶体材料具有长程无序性，不存在任何对称性。
而准晶是介于晶体和非晶体之间的固体，是具有准周期长程平移对称性(不具有晶体所应有的平移对称性)和n≥5的取向对称性，使得准晶合金具有比较低的表面自由能，具体是与以下三个因素有关：
(1)表面电子结构；在费米能级处存在赝能隙，并一直保持到外表面。(2)热力学因素；准晶薄膜或涂层的表面具有一定的微纳结构的粗糙度，有助于减少表面能。(3)滞后性；准晶颗粒的曲面增大了临界湿润角，牵制了试图湿润表面的液体的运动。
采用具有以上准晶合金保护层32的感受器30，在使用中来自于可抽吸材料A的水汽、气溶胶冷凝油等无法在准晶合金保护层32表面铺展开，从而能维持在大体呈球形的形状容易从感受器30上分离。同时掉落在感受器30上的烟渣、积碳等固相有机物难以顽固地结合在保护层32上，在可抽吸材料A例如烟支抽完后拔出的过程中会随着烟支一起被带离感受器30表面，而不会在感受器30部件上形成顽固的粘附或沉积。
并且采用准晶合金保护层32，在高温时具有超塑性，可以缓解感受器30由于热膨胀系数不同而造成的热应力。另外，准晶材料具有优良的耐蚀性能和抗氧化性，防止感受器30氧化生锈等。
进一步，在可选的实施例中，准晶合金保护层32是Al-Fe、Al-Cu-Fe、Al-Cu-Fe-Si、Al-Cu-Fe-Cr、Al-Cu-Fe-Cr-Si、Al-Cu-Co、Al-Cu-Co-Si、Al-Cu-Cr、Al-Co-Ni、Al-Mn、Al-Pd-Mn、Ga-Mn、Bi-Mn、Mg-Zn-Nd或者Ti-Zr-Ni等一系列的准晶合金材料中的至少一种。在优选的实施例中，考虑到Al-Cu-Fe系比较容易获得稳定的准晶，我们采用Al-Cu-Fe作为优选实施例的薄膜涂层材料。
在更加优选的实施例中，通过设置具有准晶合金保护层32的厚度约为100～500μm，并且尽量避免高于500μm以上，以消除准晶合金相对低导热率的不足。并且在优选的实施例中，准晶合金保护层32是含有Al的合金，可以相对提升导热效率。
在更加优选的实施例中，通过采用的准晶合金保护层32对水的静态接触角大于120度，与气溶胶冷凝油的接触角大于105度。
进一步，为了便于对采用以上具有准晶合金保护层32的感受器30的在强度、防粘附、耐受性能上的进步性进行验证，以下通过具体实施例对制备的感受器30进行示例和结果说明。
实施例1
本申请实施例1以制备具有Al-Cu-Fe的准晶合金保护层32的片状感受器30为例进行描述。
S10，材料前处理，具体：
S11，获取J185标准的坡莫合金材质的如图3所示形状的金属本体31，并将表面清洗干燥；
S12，将金属本体31用180目～400目白刚玉砂对发热针表面进行喷砂处理，基于提升Al-Cu-Fe的准晶合金保护层32与金属本体31结合强度的要求，可按照最终金属本体31表面粗糙度3～5微米进行打砂；
S13，对金属本体31使用丙酮进行超声清洗，使表面洁净；
S20，形成Al-Cu-Fe的准晶合金保护层32：将按照Al 65Cu 20Fe 15合金比例获取的粒度为15～100μm的铝粉、铜粉和铁粉，作为热喷涂材料，采用超音速火焰喷涂设备在金属本体31表面进行喷涂；喷涂中，超音速火焰喷涂设备采用液体丙烷为燃料，液态丙烷经过汽化器气化后，在喷枪的燃烧室与压缩氧气混合燃烧，经过拉瓦尔喷嘴加速后，获得超音速火焰束流。使Al 65Cu 20Fe 15准晶合金粉末经空气束流通过轴向注粉器注入喷枪的燃烧室，该合金粉末在超音速火焰束流的作用下被加热和加速，高速合金粉末束流冲击到金属本体31表面形成涂层，形成带有准晶合 金保护层32的感受器30。喷涂过程中金属本体31保持不停地旋转，使涂层的厚度均匀。
S30，将以上步骤S20处理后的带有准晶合金保护层32的感受器30于真空炉进行热处理，热处理过程中炉内压力控制在10 3Pa以内(可以通入适量的氩气50～300sccm作为保护气体)，热处理温度700～900℃，热处理时间1～5小时，使准晶合金保护层32的准晶相更加致密和稳定。
S40，为了验证制备的Al 65Cu 20Fe 15准晶合金的保护层32表面自净能力，将具备保护层32的感受器30进行如下性能验证：
S41，微观形貌的检测，通过扫描电镜检测的不同倍数的微观形貌参见图4和图5所示；其中，图4是准晶合金的保护层32表面500倍的扫描电子显微照片，图5是感受器30的剖面100倍的扫描电子显微照片；从图4和图5中可以观察到准晶涂层表面虽然存在气孔，但是整体形貌致密粉末熔化充分，涂层中孔隙的分布较为均匀。
S42，并对其中保护层32的其中一选取点进行XRD衍射仪分析，所得分析的相成分如图6所示，包括主相准晶I相、少量准晶类似相β相、晶体相θ相外，还生成了极少量的晶体相α相，这是由于原材料、以及喷涂工艺和后续处理等多种过程综合引起的。
S43：表面摩擦因素的对比测试：
S431，测量以上感受器30表面的摩擦因素：具体利用CETR-UMT磨擦磨损实验机进行，时间为30min、每隔5min取点并记录摩擦因数，做出摩擦因数与摩擦时间的变化曲线，如图7所示。从图7测试的结果看，开始时摩擦因数一般较小，随后增大并趋于稳定，同时又伴有小范围的波动，在15～20min范围内摩擦因数有所降低，最后又开始略微增加直至平稳。这是因为开始时试样不光滑，实际接触面积较小，二者之间产生的粘着强度弱，导致摩擦因数较小。样品表面微凸体被磨掉后实际接触面积增大，摩擦热效应随之增大，摩擦振动加剧，此时摩擦因数开始增大并达到最大值。进一步摩擦后，摩擦过程中被磨掉的微粒逐步磨碎成细小颗粒，摩擦轨道变得光滑而摩擦阻力减小，摩擦因数略降低后最终趋于平稳；
S432，为了对以上含有准晶合金保护层32的感受器30的表面的光滑的提升进行对比，同时对直接采用J185坡莫合金的金属本体31直接相同的方式进行表面摩擦因素测试，其结果参见图8所示；从图8所示的摩擦因素的对比测试的结果中，整个摩擦过程准晶涂层的摩擦因数要比准晶涂层的摩擦因数的一倍左右，表明准晶合金涂层具有低的摩擦因数。
S44，进一步为检测所制备的Al 65Cu 20Fe 15准晶合金保护层32的强度，通过常用的Micromet-6030型显微硬度计测量保护层32的显微硬度Hv(5.2～7.0GPa)，这一硬度比常用铝合金(0.6～0.9GPa)大约是10倍。
S45，GB2423.17标准48H盐雾测试：配置5％盐水置于盐雾机内，然后把盐雾机内温度设置为35℃开始喷雾，持续48小时，感受器30样品表面无腐蚀锈点，样品能达到盐雾测试的耐受标准。
S46，标准抗污性能测试：涂油性奇异笔，放置24小时后，用酒精棉球擦拭，可完全擦拭，表面干净。
S47，防气溶胶冷凝油粘附性测试：用接触角测量仪JC-2000C1(上海中晨数字技术设备有限公司)测量PG/VG(甘油/蔬菜甘油)中添加有0.5wt％尼古丁的烟油在感受器30表面的接触角，测试的结果如图9所示，可达108°，如果在更加精密的制备工艺和原料纯度更进一步降低晶体相后还能进一步提升；
S48，防烟渣粘附测试：将具有该感受器30的气雾生成装置进行加热不燃烧的烟支(菲利普莫里斯-IQOS)进行抽吸，每次抽吸完成一支烟支之后，查看使用后的烟渣、气溶胶冷凝油在感受器30表面粘附状况。
结果显示，抽吸第1至第12支烟支后感受器30表面有分散的小颗粒粉尘(面积小于1mm 2)并随着抽吸烟支的增加逐渐增加，但颗粒尺寸较小，同时从烟支内散落至感受器30表面的烟丝和冷凝油渍仅是轻微粘靠，可被吹落和晃动之后脱落，无形成顽固的沉积和结块；到第13支烟后，感受器30表面开始呈现肉眼显著可见的烟渣和冷凝油的凝聚结块(块状面积大于4mm 2)。
对比例1
在该对比例1中将常用的标准SS430不锈铁和J185坡莫合金的感受器30分别进行如下三项对比性能测试：
S10，GB2423.17标准48H盐雾测试：配置5％盐水置于盐雾机内，然后把盐雾机内温度设置为35℃开始喷雾，持续48小时；
结果中，标准SS430不锈铁材质的48H盐雾测试表面形成较淡并可视的锈斑点，J185坡莫合金材质能通过48H盐雾测试。
S20，表面防水和防气溶胶冷凝油的测试：通过在标准SS430不锈铁材质和J185坡莫合金的感受器30表面滴微量冷凝油后查看油滴状态并用接触角测量仪JC-2000C1(上海中晨数字技术设备有限公司)测量 其表面的接触角测试；结果中首先小油滴扩散之后均呈基本平坦的状态，说明SS430不锈铁材质和J85坡莫合金表面形貌不足以维持液滴的表面张力维持其球状形态，并测试SS430不锈铁材质感受器30的接触角为58度、J185坡莫合金感受器30的接触角约为65度，水滴在表面是倾向于平塌的偏铺展的形态；
S30，防烟渣粘附测试：结果显示，抽吸第5～6支烟时，SS430不锈铁材质和J85坡莫合金的感受器30表面开始呈现肉眼显著可见的烟渣和冷凝油的凝聚结块(块状面积大于4mm 2)，口吹和晃动无法脱落，需要用酒精棉球擦拭。
从以上可以看出本申请的表面具有准晶合金保护层的感受器，在防止加热不燃烧烟支被加热后的烟渣、冷凝油等粘附上效果更佳优良，并可以提升SS430不锈铁和J185坡莫合金等的感受器的硬度、耐腐蚀性等，在寿命和稳定性上更加优良。
或者在本申请的一个变化实施例中，以上采用电磁感应方式加热可抽吸材料A的感受器30，还可以是被构造成图3所示的销钉或刀片状的电阻式的加热器，而该电阻式的加热器表面具有以上准晶合金的保护层，在使用中通过其低表面自由能的特性阻止来自可抽吸材料A的气溶胶冷凝油、烟渣等的粘附和沉积。
通常在可选的实施例中，电阻式的加热器通常包括陶瓷衬底比如氧化锆陶瓷、以及通过印刷或沉积等方式形成在陶瓷衬底上的图案化的导电轨迹；其中，导电轨迹是采用电阻发热材料制备的，从而在供电时通过电阻发热的方式对可抽吸材料A进行加热。
当然，在该电阻式的加热器表面形成准晶合金的保护层时，由于准晶合金自身基于其晶相结构具有较低的导电性能，因而在实施例中可以直接印刷或沉积在电阻式的加热器表面。或者在更加优选的实施例中，可以先对电阻式的加热器表面绝缘处理后，再形成准晶合金的保护层。
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。
