气溶胶生成装置100还包括线路板3、按键4和电芯7。固定壳62包括前壳621与后壳622，前壳621与后壳622固定连接，线路板3和电芯7均设置在固定壳62内，电芯7与线路板3电连接，按键4凸设在外壳61上，通过按压按键4，可以实现对加热器11的通电或断电。线路板3还连接有一充 电接口31，充电接口31裸露于底盖64上，用户可以通过充电接口31对气溶胶生成装置100进行充电或升级，以保证气溶胶生成装置100的持续使用。

图3-图5是本申请实施方式提供的一种加热组件，加热组件包括加热器11、电极连接件12、温度传感器13以及保持件14。加热器11包括：
基体111，内部形成有适于收容气溶胶形成基质的腔室。
具体地，基体111包括近端和远端，延伸于近端和远端之间的表面。基体111内部中空形成有适于收容气溶胶形成制品的腔室。基体111可以为管状，例如圆柱体状、棱柱体状或者其他柱体状。基体111优选为圆柱体状，腔室即为贯穿基体111中部的圆柱体状孔，该孔的内径略大于气溶胶形成制品的外径，便于将气溶胶形成制品置于腔室内对其进行加热。基体111的内径介于7mm～14mm，或介于7mm～12mm，或介于7mm～10mm。
基体111可以由石英玻璃、陶瓷或云母等耐高温且透红外线的材料制成，也可以由其它具有较高的红外线透过率的材料制成，例如：红外线透过率在95％以上的耐高温材料，具体地在此不作限定。
气溶胶形成基质是一种能够释放可形成气溶胶的挥发性化合物的基质。这种挥发性化合物可通过加热该气溶胶形成基质而被释放出来。气溶胶形成基质可以是固体或液体或包括固体和液体组分。气溶胶形成基质可吸附、涂覆、浸渍或以其它方式装载到载体或支承件上。气溶胶形成基质可便利地是气溶胶生成制品的一部分。
气溶胶形成基质可以包括尼古丁。气溶胶形成基质可以包括烟草，例如可以包括含有挥发性烟草香味化合物的含烟草材料，当加热时所述挥发性烟草香味化合物从气溶胶形成基质释放。优选的气溶胶形成基质可以包括均质烟草材料，例如落叶烟草。气溶胶形成基质可以包括至少一种气溶胶形成剂，气溶胶形成剂可为任何合适的已知化合物或化合物的混合物，在使用中，所述化合物或化合物的混合物有利于致密和稳定气溶胶的形成，并且对在气溶胶生成系统的操作温度下的热降解基本具有抗性。合适的气溶胶形成剂是本领域众所周知的，并且包括但不限于：多元醇，例如三甘醇，1,3-丁二醇和甘油；多元醇的酯，例如甘油单、二或三乙酸酯；和一元、二元或多元羧酸的脂肪酸酯，例如二甲基十二烷二酸酯和二甲基十四烷二酸酯。优选的气溶胶形成剂是多羟基醇或其混合物，例如三甘醇、1,3-丁二醇和最优选的丙三醇。
红外电热涂层112形成在基体111的表面上。红外电热涂层112可以形成在基体111的外表面上，也可以形成在基体111的内表面上。
在本示例中，红外电热涂层112形成在基体111的外表面上。红外电热涂层112接受电功率产生热量，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。
红外电热涂层112优选的由远红外电热油墨、陶瓷粉末和无机粘合剂充分搅拌均匀后涂覆在基体111的外表面上，然后烘干固化一定的时间，红外电热涂层112的厚度为30μm-50μm；当然，红外电热涂层112还可以由四氯化锡、氧化锡、三氯化锑、四氯化钛以及无水硫酸铜按一定比例混合搅拌后涂覆到基体111的外表面上；或者为碳化硅陶瓷层、碳纤维复合层、锆钛 系氧化物陶瓷层、锆钛系氮化物陶瓷层、锆钛系硼化物陶瓷层、锆钛系碳化物陶瓷层、铁系氧化物陶瓷层、铁系氮化物陶瓷层、铁系硼化物陶瓷层、铁系碳化物陶瓷层、稀土系氧化物陶瓷层、稀土系氮化物陶瓷层、稀土系硼化物陶瓷层、稀土系碳化物陶瓷层、镍钴系氧化物陶瓷层、镍钴系氮化物陶瓷层、镍钴系硼化物陶瓷层、镍钴系碳化物陶瓷层或高硅分子筛陶瓷层中的一种；红外电热涂层112还可以是现有的其他材料涂层。
电极，包括间隔设置于所述基体111上的第一电极113和第二电极114，用于将电芯7提供的电功率馈送至所述红外电热涂层112。
第一电极113和第二电极114均与红外电热涂层112电性连接。第一电极113和第二电极114为导电涂层，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。
第一电极113和第二电极114沿基体111的中心轴对称设置。第一电极113和第二电极114均沿着基体111轴向方向延伸且呈长条形状。第一电极113和第二电极114的轴向延伸长度均与红外电热涂层112的轴向延伸长度相同。第一电极113和第二电极114的周向延伸长度或者宽度介于0.2mm～5mm；优选的介于0.2mm～4mm；进一步优选的介于0.2mm～3mm；进一步优选的介于0.2mm～2mm；进一步优选的介于0.5mm～2mm。这样，第一电极113和第二电极114将红外电热涂层112沿着基体111的周向方向分隔成两个子红外电热涂层。在第一电极113和第二电极114导电之后，电流可以经由红外电热涂层112，从其中一个电极大致沿着基体111的周向方向流向另一个电极。
在一示例中，电极或者红外电热涂层112与基体111的近端或者远端之间可以间隔设置。例如：在图5中，基体111外表面上的B1部分和B2部分均不设置电极和红外电热涂层112；B1部分和B2部分的轴向延伸长度可以尽量小一些。一般的，B1部分和B2部分的轴向延伸长度介于0～1mm，即大于0且小于等于1mm；在具体示例中，可以为0.2mm、0.4mm、0.5mm、0.7mm等等。
在一示例中，电极或者红外电热涂层112与基体111的近端或者远端之间不间隔设置，即电极或者红外电热涂层112的轴向延伸长度与基体111的轴向延伸长度相同，也是可行的。这样，一方面可以增大红外电热涂层112的涂覆面积，另一方面也可以避免热量的流失。
电极连接件12与电极保持接触，以形成电连接。电极连接件12的数量与电极的数量一致，即第一电极113具有对应的电极连接件12，第二电极114具有对应的电极连接件12。电极连接件12可通过导线与电芯7电连接，例如：导线的一端焊接在电极连接件12上，导线的另一端与电芯7电连接(可以通过线路板3与电芯7电连接，也可以直接与电芯7电连接)。电极连接件12优选采用导电性好的铜、铜合金、铝或铝合金材料，表面镀银或镀金，以减小接触电阻和提高材料表面的焊接性能。
与电极类似的，电极连接件12沿着基体111轴向方向延伸且呈条形状。电极连接件12的轴向延伸长度与电极或者红外电热涂层112的轴向延伸长度可以相同。电极连接件12的周向延伸长度或者宽度介于0.2mm～5mm；优选的介于0.2mm～4mm；进一步优选的介于0.2mm～3mm；进一步优选的介于0.2mm～2mm；进一步优选的介于0.5mm～2mm。电极连接件12的厚度介于0.05mm～1mm，即可以做的薄些；在具体示例中，电极连接件12的厚度可以为0.1mm、0.2mm、0.4mm、0.5mm等等。优选的实施中，电极连接件12的轴向延伸长度大于电极或者红外电热涂层112的轴向延伸长度，但小于电极或者红外电热涂层112的轴向延伸长度与B2部分的轴向延伸长度之和；或者，电极连接件12的轴向延伸长度大于电极或者红外电热涂层112的轴向延伸长度与B2部分的轴向延伸长度之和，即电极连接件12的上端与电极或者红外电热涂层112的上端齐平，而电极连接件12的下端延伸出基体111的远端；这样，利于导线焊接在电极连接件12上。进一步优选的实施中，电极连接件12的下端与基体111的远端之间的距离介于1mm～10mm；优选的介于1mm～8mm；进一步优选的介于1mm～6mm；进一步优选的介于1mm～4mm。
基体111的外表面具有预设位置的标记A，以使得用户可根据标记A将温度传感器13装配到预设位置，即进行定位。标记A可通过印刷或喷涂等方式将颜料标记在预设位置。通常的，预设位置位于红外电热涂层112轴向的中间位置。这样，可通过温度传感器13获取用于控制加热器11的最佳温度。
保持件14用于将电极连接件12保持在电极上，和/或将温度传感器13保持在标记A上。保持件14包括高温胶带或者热缩管；在实际的应用中，可将高温胶带直接缠绕在电极连接件12和/或温度传感器13上；或者将热缩管套接在电极连接件12和/或温度传感器13外，然后通过升温使其收缩并紧固电 极连接件12和/或温度传感器13。优选的实施中，电极连接件12部分裸露在保持件14外；这样，利于导线焊接在电极连接件12上。
需要说明的是，在其它示例中，电极连接件12可直接与红外电热涂层112保持接触并形成电连接，也是可行的。此时，不设置第一电极113和第二电极114，也是可行的。
图6是本申请实施方式提供的另一种加热器，与图3-图5示例不同的是，
基体111外表面上的B3部分将红外电热涂层112分隔成上下两个可独立控制的加热区域，即红外电热涂层1121、红外电热涂层1122，B3部分的轴向延伸长度可以尽量小些，例如0.4mm～1mm，优选的为0.4mm～0.8mm，进一步优选的为0.5mm；
电极还包括间隔设置于所述基体111上的第三电极115，即第一电极113、第二电极114以及第三电极115均是相互间隔的；第三电极115与红外电热涂层1121以及红外电热涂层1122均保持接触以形成电连接，第一电极113与红外电热涂层1121保持接触以形成电连接，第二电极114与红外电热涂层1122保持接触以形成电连接。
这样，通过控制第一电极113、第二电极114以及第三电极115的通电，可以实现对所述气溶胶形成基质进行分段加热；例如：先启动红外电热涂层1121进行加热(控制第一电极113和第三电极115通电)，再启动红外电热涂层1122进行加热(控制第二电极114和第三电极115通电)；或者，先启动红外电热涂层1121进行加热(控制第一电极113和第三电极115通电)，再启动红外电热涂层1121和红外电热涂层1122一起进行加热(控制第一电极113、第二电极114和第三电极115一起通电)。
在图6的示例中，红外电热涂层1121与基体111的近端没有间隔设置，而红外电热涂层1122与基体111的远端间隔设置(参考图中的B4)。
在图6的示例中，第三电极115的轴向延伸长度为红外电热涂层1121的轴向延伸长度、B3部分的轴向延伸长度以及红外电热涂层1122的轴向延伸长度之和；第一电极113的轴向延伸长度与红外电热涂层1121的轴向延伸长度相同；第二电极114的轴向延伸长度与红外电热涂层1122的轴向延伸长度相同。
与图3-图5示例类似的，可以通过一个或多个温度传感器13测量红外电 热涂层1121和/红外电热涂层1122所在区域的温度，进而用于控制加热器11的温度。
与图3-图5示例类似的，可以在红外电热涂层1121和/或红外电热涂层1122设置温度传感器13对应的标记。
与图3-图5示例类似的，可以通过电极连接件12与电极保持接触并与电芯7电连接。
优选的实施中，第三电极115对应的电极连接件12，其轴向延伸长度大于第三电极115的轴向延伸长度与B4部分的轴向延伸长度之和，即第三电极115对应的电极连接件12的上端与第三电极115齐平，而下端延伸出基体111的远端；第一电极113对应的电极连接件12，其轴向延伸长度与第一电极113的轴向延伸长度相同；第二电极114对应的电极连接件12，其轴向延伸长度大于第二电极114的轴向延伸长度与B4部分的轴向延伸长度之和，即第二电极114对应的电极连接件12的上端与第二电极114齐平，而下端延伸出基体111的远端。这样，每一个电极连接件12对应的导线，其一端可焊接在电极连接件12上，另一端从基体111的远端伸出去与电芯7电连接。
图7-图8是本申请实施方式提供的又一种加热器，与图3-图5示例不同的是，
基体11的整个外表面形成有红外电热涂层112；电极包括间隔设置于所述基体111上的第一电极113、第二电极114、第三电极115以及第四电极116。这样，第一电极113、第二电极114、第三电极115以及第四电极116将红外电热涂层112分隔成周向依次分布的四个红外电热涂层。在控制第一电极113和第三电极115通电、第三电极115和第四电极116通电时，第一电极113和第二电极114之间的红外电热涂层1122、第三电极115和第四电极116之间的红外电热涂层1122，接受电功率辐射红外线以加热气溶胶形成基质，而第一电极113和第四电极116之间的红外电热涂层1121、第三电极115和第二电极114之间的红外电热涂层1121形成短路。反之，第一电极113和第四电极116之间的红外电热涂层1121、第三电极115和第二电极114之间的红外电热涂层1121接受电功率辐射红外线以加热气溶胶形成基质，而第一电极113和第二电极114之间的红外电热涂层1122、第三电极115和第四电极116之间的红外电热涂层1122形成短路。
在图7-图8的示例中，第一电极113、第二电极114、第三电极115以及第四电极116的轴向延伸长度均与红外电热涂层1121或者红外电热涂层1122的轴向延伸长度相同。
需要说明的是，图6的示例、图7-图8的示例，电极的设计可以通用。例如：与图6示例类似的，在图7-图8的示例中，可以采用三个电极来实现分段加热；与图7-图8示例类似的，在图6的示例中，可以采用四个电极来实现分段加热(红外电热涂层1121和红外电热涂层1122上均设置有两个轴向延伸的电极)。
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，但是，本申请可以通过许多不同的形式来实现，并不限于本说明书所描述的实施例，这些实施例不作为对本申请内容的额外限制，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。并且，上述各技术特征继续相互组合，形成未在上面列举的各种实施例，均视为本申请说明书记载的范围；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。
