红外电热涂层111接受电功率产生热量，进而辐射出一定波长的红外线，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。
在本示例中，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。
红外电热涂层111与基体110的上端间隔设置，间隔距离介于0.2mm～1mm，利于制造生产。红外电热涂层111与基体110的下端也是间隔设置的，间隔距离介于1mm～4mm，利于导电电极的布置，同时避免基体110下端的温度过高。需要说明的是，从气溶胶的流向来看，基体110的上端位于基体110下端的下游。

连接电极113a呈条形状，其轴向延伸的长度与右半部分红外电热涂层111轴向延伸的长度相同。连接电极113a将右半部分红外电热涂层111分隔成两个串联连接在导电部112a2和导电部112b2之间的子红外电热涂层(图4中的A1、A2所示)，子红外电热涂层A1与子红外电热涂层A2沿着基体110的周向方向分布；子红外电热涂层A1的等效电阻与子红外电热涂层A2的等效电阻可以相同，也可以不同。通过设置的连接电极113a，可以减少右半部分红外电热涂层111的整体阻值。例如，在导电部112a2和导电部112b2之间设置1个连接电极113a，右半部分红外电热涂层111的整体阻值可以减少约20％。
需要说明的是，可以根据需要，在右半部分红外电热涂层111中设置多个连接电极113a，将右半部分红外电热涂层111分隔成多个串联连接在导电部112a2和导电部112b2之间的子红外电热涂层；例如：2个连接电极113a分隔成3个串联连接在导电部112a2和导电部112b2之间的子红外电热涂层，3个子红外电热涂层的等效电阻可以都相同或者都不同，或者其中2个子红外电热涂层的等效电阻相同。
连接电极113b与此类似，分隔成的子红外电热涂层可参考图4中的A3、A4所示。
在加热器11通电后，例如耦接部112a1与电源的正极电连接，耦接部112b1与电源的负极电连接(反之亦可)，电流从导电部112a2流入，依次经过子红外电热涂层A1与子红外电热涂层A2后或者依次经过子红外电热涂层A3与子红外电热涂层A4后，从导电部112b2流出。连接电极113a和连接电极113b不与 加热器11外的电源或者电路连接，即连接电极113a和连接电极113b是悬空的，电流不能从连接电极113a直接流入，然后从导电部112b2或者导电部112a2流出。
导电电极112a、导电电极112b、连接电极113a以及连接电极113b优选的采用连续导电涂层，导电涂层可以为金属涂层，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。连接电极113a和连接电极113b的宽度介于0.5mm～3mm；或者介于0.5mm～2.5mm；具体示例中，可以为1mm、2mm。

图6是本申请实施方式提供的第二种加热器。
与图3-图4不同的是，导电电极112a和导电电极112b均呈环形状，沿基体110周向方向延伸；导电电极112a和导电电极112b之间设置多个连接电极113a，连接电极113a也呈环形状；多个连接电极113a将红外电热涂层111分隔成4个串联连接在导电部112a2和导电部112b2之间的子红外电热涂层(图中的A1、A2、A3、A4所示)。4个子红外电热涂层的等效电阻都不同。这样，一方面降低了红外电热涂层111的整体阻值，另一方面可改善基体110温度场的均匀性。
在该示例中，4个子红外电热涂层沿着基体110的轴向方向分布，连接电极113a沿着基体110的周向方向延伸的长度与红外电热涂层111沿着基体110的周向方向延伸的长度相同。
需要说明的是，在其它示例中，连接电极113a呈弧形状也是可行的。
在加热器11通电后，例如导电电极112a与电源的正极电连接，导电电极112b与电源的负极电连接，电流从导电电极112a流入，依次经过子红外电热涂层A1、子红外电热涂层A2、子红外电热涂层A3、子红外电热涂层A4后，从导电电极112b流出。

连接电极113a设置在导电电极112a和导电电极112c之间，连接电极113a将上半部分的加热区域分隔成两个串联连接在导电电极112a和导电电极112c之间的子红外电热涂层(图中的A1、A2所示)。
连接电极113b设置在导电电极112c和导电电极112b之间，连接电极113b将下半部分的加热区域分隔成两个串联连接在导电电极112c和导电电极112b之间的子红外电热涂层(图中的A3、A4所示)。
在启动上半部分的加热区域时，例如导电电极112a与电源的正极电连接，导电电极112c与电源的负极电连接，电流从导电电极112a流入，依次经过子红外电热涂层A1、子红外电热涂层A2后，从导电电极112c流出。
在启动下半部分的加热区域时，例如导电电极112c与电源的正极电连接，导电电极112b与电源的负极电连接，电流从导电电极112c流入，依次经过子红外电热涂层A3、子红外电热涂层A4后，从导电电极112b流出。
图8是本申请实施方式提供的第四种加热器。
与图3-图4不同的是，导电电极112a和导电电极112b均沿基体110的轴向方向螺旋延伸；导电电极112a和导电电极112b之间设置1个连接电极113a，连接电极113a也沿基体110的轴向方向螺旋延伸、且螺旋延伸的高度与红外电热涂层111沿着基体110的轴向方向延伸的长度相同；连接电极113a将红外电 热涂层111分隔成2个串联连接在导电电极112a和导电电极112b之间的子红外电热涂层(图中的A1、A2所示)。
在加热器11通电后，例如导电电极112a与电源的正极电连接，导电电极112b与电源的负极电连接，电流从导电电极112a流入，依次经过子红外电热涂层A1、子红外电热涂层A2后，从导电电极112b流出。
需要说明的是，对于图7中通过增加导电电极112c实现对气溶胶形成基质的分段加热，同样适用于图3-图4、图8的加热器。可以理解的是，可以通过多个导电电极实现多段加热。
图9-图10是本申请实施方式提供的第五种加热器。
与图3-图4不同的是，红外电热涂层111包括间隔设置的两个红外电热涂层，图中的红外电热涂层111a、红外电热涂层111b所示。其中，红外电热涂层111a相比红外电热涂层111b更靠近气溶胶生成装置100的嘴端。红外电热涂层111a与红外电热涂层111b之间的间隔距离介于0.2mm～1mm。
导电电极112a包括沿基体110周向方向延伸的耦接部112a1以及自耦接部112a1朝向基体110上端的方向轴向延伸的导电部112a2。耦接部112a1呈弧状，耦接部112a1与红外电热涂层111b间隔设置，耦接部112a1设置在红外电热涂层111b与基体110的下端之间；可以在耦接部112a1上焊接导线，以与加热器11外的电源，例如电芯7或者电芯7转换后的电压，形成电连接，也可以通过其它电连接件与电源电连接。导电部112a2呈条形状，轴向延伸的长度大于红外电热涂层111b轴向延伸的长度，导电部112a2的上端与红外电热涂层111b的上端齐平；导电部112a2与红外电热涂层111b保持接触，以形成电连接。
导电电极112b呈条形状，其轴向延伸的长度与红外电热涂层111a轴向延伸的长度是相同的。导电电极112b与红外电热涂层111a保持接触，以形成电连接。
导电电极112c的结构与导电电极112a类似。导电电极112c的耦接部112c1设置在红外电热涂层111b与基体110的下端之间，导电部112c2呈条形状，但其轴向延伸的长度大于红外电热涂层111a与红外电热涂层111b轴向延伸的长度之和，导电部112c2的上端与红外电热涂层111a的上端齐平。导电部112c2与红外电热涂层111a、红外电热涂层111b均保持接触，以形成电连接。
连接电极113a和连接电极113b均呈条形状且设置在红外电热涂层111b中。 连接电极113a和连接电极113b的轴向延伸的长度与红外电热涂层111b轴向延伸的长度相同。
连接电极113a设置在导电电极112a与导电电极112c之间。连接电极113a将导电电极112a与导电电极112c之间的红外电热涂层，分隔成两个串联连接在导电电极112a与导电电极112c之间的子红外电热涂层(图10中的B1、B2所示)，子红外电热涂层B1与子红外电热涂层B2沿着基体110的周向方向分布；子红外电热涂层B1的等效电阻与子红外电热涂层B2的等效电阻可以相同，也可以不同。
连接电极113b也是设置在导电电极112a与导电电极112c之间。连接电极113b将导电电极112a与导电电极112c之间的红外电热涂层，分隔成两个串联连接在导电电极112a与导电电极112c之间的子红外电热涂层(图10中的B3、B4所示)，子红外电热涂层B3与子红外电热涂层B4沿着基体110的周向方向分布；子红外电热涂层B3的等效电阻与子红外电热涂层B4的等效电阻可以相同，也可以不同。
通过设置的连接电极113a和连接电极113b，可以减少红外电热涂层111b的整体阻值。
与图7或者图8类似的，通过图9中的导电元件设置，红外电热涂层111a和红外电热涂层111b是可以独立控制的。具体地，可以控制电源向红外电热涂层111a和/或红外电热涂层111b提供加热功率；例如，先控制电源向红外电热涂层111a提供加热功率，以加热气溶胶生成制品的上半部分(与红外电热涂层111a区域对应的部分)；然后再控制电源向红外电热涂层111b提供加热功率，以加热气溶胶生成制品的下半部分(与红外电热涂层111b区域对应的部分)。反之亦可。
或者，先控制电源向红外电热涂层111a提供加热功率，以加热气溶胶生成制品的上半部分；然后再控制电源向红外电热涂层111a和红外电热涂层111b同时提供加热功率，以对整个气溶胶生成制品进行加热。
或者，先控制电源向红外电热涂层111b提供加热功率，以加热气溶胶生成制品的下半部分；然后再控制电源向红外电热涂层111a和红外电热涂层111b同时提供加热功率，以对整个气溶胶生成制品进行加热。
在控制红外电热涂层111a加热时，例如导电电极112b与电源的正极电连 接，耦接部112c1与电源的负极电连接；这样，电流从导电电极112b流入，沿着基体110的周向方向经过子红外电热涂层A1或者子红外电热涂层A2后，从导电部112c2流出。
在控制红外电热涂层111b加热时，例如耦接部112a1与电源的正极电连接，耦接部112c1与电源的负极电连接，电流从导电部112a2流入，依次经过子红外电热涂层B1、子红外电热涂层B2后，或者依次经过子红外电热涂层B4与子红外电热涂层B3后，从导电部112c2流出。连接电极113a和连接电极113b不与加热器11外的电源或者电路连接，即连接电极113a和连接电极113b是悬空的，电流不能从连接电极113a直接流入，然后从导电部112b2或者导电部112a2流出。连接电极113a和连接电极113b的存在，可以减少红外电热涂层111b的整体阻值。
图11-图12是本申请实施方式提供的第六种加热器。
与图9-图10不同的是，导电电极112a的导电部112a2，其轴向延伸的长度大于红外电热涂层111a与红外电热涂层111b轴向延伸的长度之和，导电部112a2的上端与红外电热涂层111a的上端齐平。导电部112a2与红外电热涂层111a和红外电热涂层111b均保持接触以形成电连接。导电电极112b和导电电极112d均设置在红外电热涂层111a区域中，且与红外电热涂层111a保持接触以形成电连接。导电电极112b、导电部112a2、导电电极112d、导电部112c2沿着基体110的周向方向依次间隔设置。
与图9-图10不同的是，红外电热涂层111a可以独立控制，而红外电热涂层111b是不可以独立控制的。
在控制加热器11加热时，首先通过导电电极112b和导电电极112d，控制电源向红外电热涂层111a提供加热功率；然后再通过导电电极112a和导电电极112c，控制电源向红外电热涂层111a和红外电热涂层111b同时提供加热功率。
在导电电极112b和导电电极112d通电时，位于导电电极112b和导电电极112d之间的导电部(导电电极112a的导电部112a2和导电电极112c的导电部112c2)没有通电，该导电部相当于图9-图10示例中的连接电极，进而减少红外电热涂层111a的整体阻值，使得红外电热涂层111a快速升温，可将气溶胶生成制品的上半部分快速加热，达到快速产生气溶胶的目的。
在导电电极112a和导电电极112c通电时，位于导电电极112a和导电电极112c之间的导电电极112b、导电电极112d没有通电，也是相当于图9-图10示例中的连接电极的，进而减少红外电热涂层111a的整体阻值。此时，由于红外电热涂层111a和红外电热涂层111b同时加热或者红外电热涂层111整体加热，由于导电电极112b、导电电极112d的存在，会减少红外电热涂层111a的整体阻值，使得红外电热涂层111a区域的温度得到提升，改变了整个红外电热涂层111区域的温场。
