红外电热涂层12在通电情况下能够产生热能，进而生成一定波长的红外线，例如：8μm～15μm的远红外线。当红外线的波长与气溶胶形成基质的吸收波长匹配时，红外线的能量易于被气溶胶形成基质吸收。在本申请实施方式中，对红外线的波长不作限定，可以为0.75μm～1000μm的红外线，优选的为1.5μm～400μm的远红外线。

导电模块11包括设置在基体1上的第一导电部111和第二导电部112。第一导电部111和第二导电部112均至少部分地与红外电热涂层 12电性连接，以使得电流可以经由红外电热涂层12从其中一个导电部流向另一个导电部。第一导电部111和第二导电部112的极性相反，例如：第一导电部111为正极、第二导电部112为负极；或者第一导电部111为负极、第二导电部112为正极。优选的将红外电热涂层12涂覆在基体1的外表面，第一导电部111设于基体1靠近第一端的外表面，第二导电部112设于基体1靠近第二端的外表面。若红外电热涂层12涂覆在基体1的内表面，导电模块11也可以设置在基体1的内表面、或者横跨基体1的内表面和外表面。
在本示例中，第一导电部111和第二导电部112均呈圆环状(环形导电部)，第一导电部111和第二导电部112可以为涂覆在基体1靠近第一端和第二端位置的外表面的圆环形导电涂层，导电涂层可以为金属涂层或导电胶带等，金属涂层可以包括银、金、钯、铂、铜、镍、钼、钨、铌或上述金属合金材料；也可以是套接在基体1靠近第一端和第二端位置的外表面的圆环形导电片，导电片为金属导电片，例如铜片、钢片等等。
请参考图4所示，在一示例中，导电模块11包括第一导电部111、第二导电部112和第三导电部113。第一导电部111、第二导电部112与图3类似，可参考前述内容。第三导电部113设于第一导电部111和第二导电部112之间的基体1外表面，第三导电部113与红外电热涂层12导电连接，第三导电部113将红外电热涂层12沿基体1纵向方向分隔为两个加热区域(图中的121、122所示)，以实现对腔室内的气溶胶形成基质的分段加热。在该实施方式中，第三导电部113将红外电热涂层12分割为两个加热区域，可以通过控制第一导电部111、第二导电部112以及第三导电部113的通断电实现对腔室内的气溶胶形成基质的分段加热。
请参考图5所示，在一示例中，导电模块11包括第一导电部111、第二导电部112、第三导电部113和第四导电部114。第一导电部111、第二导电部112与图3类似，可参考前述内容。第三导电部113自第二导电部112沿着基体1的纵向方向延伸(方向朝向第一导电部111)，第 四导电部114自第一导电部111沿着基体1的纵向方向延伸(方向朝向第二导电部112)，即第三导电部113和第四导电部114均为沿着基体1的纵向方向的长条形导电部。这样，与图3所示的电流沿基体1的纵向方向从基体1的第一端流动到第二端相比(例如：第一导电部111流动到第二导电部112)，本示例中的电流沿基体1的圆周方向流动，缩短了电流在红外电热涂层12中的流动距离，减小了电流路径中的红外电热涂层12的电阻。
请参考图6所示，在一示例中，导电模块11包括第一导电部111和第二导电部112，与图3不同的是，第一导电部111和第二导电部112均为长条形导电部，且沿着基体1的纵向方向进行设置。同样的，与图3所示的电流沿基体1的纵向方向从基体1的第一端流动到第二端相比(例如：第一导电部111流动到第二导电部112)，本示例中的电流沿基体1的圆周方向流动，缩短了电流在红外电热涂层12中的流动距离，减小了电流路径中的红外电热涂层12的电阻。
请参考图7所示，柔性电路板2包括柔性基材20，形成在柔性基材20上的第一电极21、第二电极22以及用于采集基体1的温度数据的温度采集模块23；
其中，柔性基材20固定在基体1的表面上，使得第一电极21与第一导电部111电性连接、第二电极22与第二导电部112电性连接，且温度采集模块23接触或靠近基体1的表面的目标位置。目标位置为适于采集基体1的温度数据的预设位置，预设位置可由用户经验或者实验测试确定的位置。一般的，将温度采集模块23设置在红外电热涂层12区域对应的位置。由于温度采集模块23集成在柔性电路板2中，当柔性电路板2包覆在基体1外围时，温度采集模块23的位置相对地稳定，保证了温度数据采集的一致性，便于对加热器的加热温度进行控制。
柔性基材20包括包覆基体1表面的包覆部分(图中的A所示)、以及未包覆基体1表面的延伸部分(图中的B所示)。延伸部分B自包覆部分A的一端沿着远离基体1的纵向方向延伸。延伸部分B具有用于与外部元器件连接的多个连接部件24，第一电极21、第二电极22以及温 度采集模块23分别通过导电线路与连接部件24连接。连接部件24包括但不限于焊点、焊接孔、焊盘、过孔、接线端子以及其他电气连接的部件。通过延伸部分B、导电线路可将第一电极21和第二电极22延伸到远离基体1的位置，例如：连接部件24所在位置。
以图12为例，连接部件24为焊盘，该焊盘用于连接主控制电路板4。主控制电路板4用于控制加热器的加热温度、以及对烟具的电池进行管理。现有技术中，通常是采用多条导线直接与主控制电路板4进行焊接，该方式存在的问题是，一方面在加热过程中，基体的温度较高，容易引起导线溶胶短接，具有极大的安全隐患；另一方面焊点数量过多，增加了焊接工序，存在错焊或者错接的风险。在本示例中，通过插排(或者插针)5，一端焊接在延伸部分B上的焊盘，另一端与主控制电路板4焊接，很好地避免了现有方式存在的问题，节省了空间。
包覆部分A卷曲之后(包覆基体1表面，卷曲方向可参考图中的箭头所示)可形成适于圆柱体状的基体1的外表面的形状，并包覆基体1的整个外表面。包覆部分A沿展开方向(图中箭头相反的方向)的宽度大于延伸部分B沿展开方向的宽度。
需要说明的是，在其他示例中，包覆部分A卷曲之后可包覆基体1表面的一部分也是可以实现的，例如，包覆第一导电部111和第二导电部112之间的红外电热涂层12。在其他示例中，柔性基材20只有包覆部分A也是可以实现的。
在本示例中，当柔性基材20包覆基体1表面时，第一电极21与第一导电部111之间至少部分面积接触，第二电极22与第二导电部112之间至少部分面积接触，确保第一电极21与第一导电部111保持电性接触，第二电极22与第二导电部112保持电性接触。以下参考图3-图10进行说明：
请结合图3和图7进行理解，在本示例中，形成在柔性基材20上的第一电极21和第二电极22均为横向方向(参考基体1的横向方向或者图中箭头所示方向)的长条形电极部。在柔性基材20卷曲之后，第一电极21和第二电极22均形成环形状电极，环形状电极与图3中的环 形导电部(第一导电部111和第二导电部112)相对应，进而使得当柔性基材20包覆基体1表面时，第一电极21与第一导电部111保持接触，第二电极22与第二导电部112保持接触。
请参考图5和图8进行理解，在一示例中，形成在柔性基材20上的第一电极21包括横向方向的长条形电极部211和纵向方向(参考基体1的纵向方向)的长条形电极部212(长条形电极部212自长条形电极部211上沿纵向方向延伸)，第二电极22包括沿横向方向的长条形电极部221和纵向方向的长条形电极部222(长条形电极部222自长条形电极部221上沿纵向方向延伸)。在柔性基材20卷曲之后，长条形电极部211和长条形电极部221形成环形状电极，环形状电极与图5中的环形导电部(第一导电部111和第二导电部112)的形状相对应；长条形电极部212和长条形电极部222形成纵向方向的长条形状电极，该长条形状电极与图5中的长条形导电部(第三导电部113和第四导电部114)的形状相对应，进而使得当柔性基材20包覆基体1表面时，第一电极21与第一导电部111保持接触，第二电极22与第二导电部112保持接触。

请参考图6和图9进行理解，在一示例中，形成在柔性基材20上的第一电极21和第二电极22均为纵向方向的长条形电极部。在柔性基材20卷曲之后，第一电极21和第二电极22均形成纵向方向的长条形状电极，长条形状电极与图6中的长条形导电部(第一导电部111和第二导电部112)的形状相对应，进而使得当柔性基材20包覆基体1表面时，第一电极21与第一导电部111保持接触，第二电极22与第二导电部112保持接触。
请参考图6和图10进行理解，在一示例中，形成在柔性基材20上 的第一电极21和第二电极22均为横向方向的长条形电极部。在柔性基材20卷曲之后，第一电极21和第二电极22在基体1的一端形成两个弧形状电极，弧形状电极与图6中的长条形导电部(第一导电部111和第二导电部112)相对应，进而使得当柔性基材20包覆基体1表面时，第一电极21与第一导电部111保持接触，第二电极22与第二导电部112保持接触。需要说明的是，若第一导电部111和第二导电部112均为自基体1的一端延伸到另一端的长条形导电部(在基体1的表面大致呈螺旋状)也是可行的。
在该示例中，第一电极21和第二电极22均形成在柔性基材20的一端。在柔性基材20卷曲之后，第一电极21和第二电极22在基体1的一端形成的两个弧形状电极的长度均小于长条形导电部之间的周向距离，例如，图10中的d1和d2小于图6中的D12；两个弧形状电极之间的间距均大于长条形导电部的周向宽度，例如，图10中的d12大于图6中的D22。
需要说明的是，在其他示例中，第一电极21和第二电极22可分别形成在柔性基材20上的两端、中间或者其他位置，也是可行的。
在一示例中(附图未示出)，第一电极21和第二电极22均为自柔性基材2的一端延伸到另一端的长条形电极部(在柔性基材2上大致呈斜线形状、曲线形状或者其他形状)。第一导电部111和第二导电部112均为自基体1的一端延伸到另一端的长条形导电部(在基体1的表面大致呈螺旋状)。
在柔性基材20卷曲之后，第一电极21和第二电极22形成的电极(可以为斜线形状电极、曲线形状电极、螺旋状电极等等)与长条形导电部(第一导电部111和第二导电部112)相对应，进而使得当柔性基材20包覆基体1表面时，第一电极21与第一导电部111保持接触，第二电极22与第二导电部112保持接触。
请参考图4进行理解，在一示例中，柔性电路板2包括柔性基材20，形成在柔性基材20上的第一电极21、第二电极22以及第三电极(附图未示出)。第三电极的形状可参考上述示例。
当柔性基材20包覆基体1表面时，第一电极21与第一导电部111电性连接、第二电极22与第二导电部112电性连接、第三电极与第三导电部113电性连接。
在本示例中，为了保证加热器的加热效果，第一电极21、第二电极22需要通过较大的电流，因此第一电极21和第二电极22的线宽可以设置为0.2mm～3mm，优选的第一电极21和第二电极22的线宽设置为0.2mm～1mm。
请结合图11进行理解，在一示例中，为了更好地固定第一电极21与第一导电部111、以及第二电极22与第二导电部112，保证电极与导电部的电性连接。加热器还包括第一固定件和第二固定件(图11中3所示的结构件)；所述第一固定件将第一电极21固定在第一导电部111上，所述第二固定件将第二电极22固定在第二导电部112上。
在该示例中，所述第一固定件和所述第二固定件均为具有断裂缺口(图中的a所示)的固定环，且固定环的内径小于基体1的外径。内径小和断裂缺口保证了固定环套接在基体1上有一定的干涉量，确保电极与导电部紧密贴合又能保持一定的弹性。
请结合图13进行理解，在一示例中，柔性基材20为聚酰亚胺薄膜，聚酰亚胺薄膜包括第一聚酰亚胺层201、第二聚酰亚胺层203和线路层202，其中线路层202的至少部分被定位在第一聚酰亚胺层201和第二聚酰亚胺层203之间。
在该示例中，温度采集模块23可以为具有电阻温度系数的导电材料，该导电材料被设置在线路层202。
在一示例中，加热器还包括呈中空状的隔热管；
隔热管包覆在柔性电路板2的外围。隔热管可以避免大量的热量传递到烟具外壳上而导致用户觉得烫手。
在该示例中，由于红外电热涂层12存在热量以传导或对流方式扩散的现象，因此隔热管的内表面上还可涂覆有反射涂层，以将基体1上的红外电热涂层12发出的红外线反射回基体1内部来加热位于腔室内的气溶胶形成基质，提高加热效率；另一方面可起到隔热的效果，避免 烟具的外壳温度过高，降低用户体验。
在该示例中，反射涂层包括金属、金属氧化物中的至少一种。具体地，可为金、银、镍、铝、金合金、银合金、镍合金、铝合金、金的氧化物、银的氧化物、镍的氧化物和铝的氧化物、氧化钛、氧化锌、二氧化铈中一种或多种制作而成。反射涂层的厚度在0.3μm-200μm之间。
在该示例中，隔热管包括隔热材料，隔热材料可以为隔热胶、气凝胶、气凝胶毡、石棉、硅酸铝、硅酸钙、硅藻土、氧化锆等。隔热管也可以包括真空隔热管。

壳体组件6包括外壳61、固定壳62、固定件63以及底盖64，固定壳62、固定件63均固定于外壳61内，其中固定件63用于固定基体1，固定件63设置于固定壳62内，底盖64设于外壳61一端且盖设外壳61。具体的，固定件63包括上固定座631和下固定座632，上固定座631和下固定座632均设于固定壳62内，基体1的第一端和第二端分别固定在上固定座631和下固定座632上，底盖64上凸设有进气管，下固定座632背离上固定座631的一端与进气管连接，上固定座631、基体1、下固定座632以及进气管同轴设置，且基体1与上固定座631、下固定座632之间密封，下固定座632与进气管也密封，进气管与外界空气连通以便于用户抽吸时可以顺畅进气。
烟具100还包括柔性电路板2、固定环3、主控制电路板4、插排5以及电池8，两个固定环3分别套接在基体1的第一端和第二端，柔性电路板2包覆在基体1外围，插排5一端焊接在柔性电路板2的连接部件24(焊盘)上，另一端焊接在主控制电路板4。固定壳62包括前壳 621与后壳622，前壳621与后壳622固定连接，主控制电路板4和电池8均设置在固定壳62内，电池8与主控制电路板4电性连接，柔性电路板2与主控制电路板4也电性连接，按键凸设在外壳61上，通过按压按键，可以实现对基体1外表面上的红外电热涂层12的通电或断电。主控制电路板4还连接有一充电接口，充电接口裸露于底盖64上，用户可以通过充电接口对烟具100进行充电或升级，以保证烟具100的持续使用。
烟具100还包括隔热管7，隔热管7设置在固定壳62内，隔热管7套设在基体1外，隔热管7可以避免大量的热量传递到外壳61上而导致用户觉得烫手。具体的，隔热管7内还涂覆有反射涂层，以将基体1上的红外电热涂层12发出的红外管反射回基体1内部来加热位于腔室内的气溶胶形成基质，提高加热效率。
柔性电路板2集成了NTC温度传感器，用于检测基体1的实时温度，并将检测的实时温度传输到主控制电路板4，主控制电路板4根据该实时温度调节流经红外电热涂层12上的电流的大小。具体的，当NTC温度传感器检测到基体1内的实时温度较低时，譬如检测到基体1内侧的温度不到150℃时，主控制电路板4控制电池8输出较高的电压给导电模块11，进而提高红外电热涂层12中馈入的电流，提高气溶胶形成基质的加热功率，减少用户抽吸第一口烟所要等待的时间。当NTC温度传感器检测到基体1的温度为150℃-200℃时，主控制电路板4控制电池8输出正常的电压给导电模块11。当NTC温度传感器检测到基体1的温度在200℃-250℃时，主控制电路板4控制电池8输出较低的电压给导电模块11；当NTC温度传感器检测到基体1内侧的温度在250℃及以上时，主控制电路板4控制电池8停止输出电压给导电模块11。
