图3是本申请实施方式提供的一种加热器12，加热器12包括：
基体121，被构造成沿腔室11的轴向方向延伸并围绕腔室11的管状。
具体地，基体121包括第一端和第二端，延伸于第一端和第二端之间的表面。基体121可以为圆柱体状、棱柱体状或者其他柱体状。基体121优选为圆柱体状，贯穿基体121中部的圆柱体状孔形成至少部分腔室，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121可以由石英玻璃、陶瓷或云母等耐高温且透明的材料制成，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。
红外电热涂层122形成在基体121的表面上。红外电热涂层122可以形成在基体121的外表面上，也可以形成在基体121的内表面上。
红外电热涂层122接受电功率产生热量，进而产生一定波长的红外线，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122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121的外表面上，然后烘干固化一定的时间，红外电热涂层122的厚度为30μm-50μm；当然，红外电热涂层122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121的外表面上；或者为碳化硅陶瓷层、碳纤维层、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；红外电热涂层还可以是其他材料涂层，例如：以碳为部分或全部组成元素的衍生物和化合物，包括但不限于碳纳米管、碳纳米管薄膜、石墨烯、碳纤维、碳纤维薄膜、碳膜、碳纤维布。
导电元件，包括间隔设置于基体121上的第一电极123和第二电极124，用于将所述电功率馈送至红外电热涂层122。
第一电极123和第二电极124均至少部分地与红外电热涂层122电性连接，以使得电流可以经由红外电热涂层122从其中一个电极流向另一个电极。第一电极123和第二电极124的极性相反，例如：第一电极123为正极、第二电极124为负极；或者，第一电极123为负极、第二电极124为正极。
在本示例中，第一电极123和第二电极124均为导电涂层，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。
在本示例中，第一电极123和第二电极124沿基体121的中心轴对称设置。
第一电极123包括沿基体121周向方向延伸的耦接电极1231以及自耦接电极1231朝向所述近端轴向方向延伸的条形电极1232，耦接电极1231不与红外电热涂层122接触，条形电极1232至少部分与红外电热涂层122接触以形成电连接。
第二电极124包括沿基体121周向方向延伸的耦接电极1241以及自耦接电极1241朝向近端A轴向方向延伸的条形电极1242，耦接电极1241不与红外电热涂层122接触，条形电极1242至少部分与红外电热涂层122接触以形成电连接。
由上述可以看出，条形电极1232和条形电极1242之间分布距离均匀，可确保红外电热涂层122发热均匀，提升烟具的加热效率。耦接电极1231和耦接电极1241的设置，便于与电芯13耦接，且避免了一端连接的导线需要经过发热区域导致导线容易损坏的问题。
进一步地，请参考图2所示，气溶胶生成装置100还包括套接在基体121外的隔热管15。隔热管15具有径向方向设置的内管和外管，内管和外管之间形成密封空间，密封空间内可以抽真空、填充气体以及隔热材料等等。气体包括但不限于惰性气体、空气、二氧化碳等，隔热材料包括但不限于气凝胶、云母片、云母管、氧化铝微孔陶瓷、堇青石、岩棉板或岩棉毡等低导热率的材料。
需要说明的是，由红外电热涂层122、第一电极123和第二电极124构成的红外发射器，并不限于图3的示例。在其他示例中，红外发射器可由热激发的红外辐射层形成、或者由可卷绕在基体121上的薄膜构造 形成等等。
还需要说明的是，上述示例中，加热器12是以红外加热方式进行说明。在其他示例中，加热器12的加热方式还可以是电阻加热、电磁加热等等，并不限于此。
请再参考图2所示，气溶胶生成装置100还包括排热装置16。
排热装置16，设置在空气入口102、腔室11以及通孔之间101延伸的气体流动路径(图中的虚线箭头所示)上。具体地，排热装置16，设置在空气入口102与腔室11之间，排热装置16被构造成在启动工作之后，排出的气流方向是朝向通孔101的，即图中的虚线箭头所示方向。可以理解的，排出的气流方向朝向空气入口102也是可行的。排出的气流方向朝向通孔101，可以有利地将气溶胶生成制品中的水成分排出壳体外。排热装置16可以为风扇或者类似装置。
电路14，被配置为在加热器12启动加热之后至加热器12进入抽吸阶段之前，控制排热装置16启动工作以将加热产生的热空气沿着气体流动路径排出壳体10外。
请参考图4所示，一般的，加热器12随时间的温度变化曲线包括升温阶段、保温阶段以及抽吸阶段。
升温阶段，加热器12的温度从初始温度T0(或者环境温度)升高至最大工作温度T1。一般地，T1可以为150℃-400℃。
保温阶段，加热器12的温度在预设目标温度T1下保持一段时间，以使得气溶胶形成基质得到充分的预热，提升用户的抽吸口感。
升温阶段持续时间为t0～t2，保温阶段的持续时间为t2～t3，t0～t3即为加热器12的预热时间。一般地，加热器12的预热时间为5秒～30秒。
抽吸阶段，加热器12的温度从最大工作温度T1下降到期望工作温 度T2，期望工作温度T2为气溶胶形成基质产生气溶胶的最佳温度。一般地，T2可以为150℃-350℃。在该阶段，加热器12的温度一般保持为期望工作温度T2或者在期望工作温度T2上下波动，t4～t5为保持时间。
需要说明的是，加热器12的加热曲线并不限于图4情形。在其他示例中，加热器12的加热曲线只有升温阶段和抽吸阶段，也是可行的。
基于图4可知，为了避免了抽吸者在抽吸第一口时感觉烟气温度较高，导致灼痛感的问题，电路14应该在抽吸阶段之前(t3或者t4时间点)控制排热装置16启动工作以将加热产生的热空气沿着气体流动路径排出壳体10外。
在一示例中，气溶胶生成装置100还包括用于检测加热器12的温度信息的温度检测装置(附图未示出)；
电路14，被配置为在加热器12启动加热之后，获取所述温度检测装置检测到的加热器12的温度信息；在加热器12的温度达到预设温度时，控制排热装置16启动工作以将加热产生的气溶胶沿着气体流动路径排出壳体10外。
其中，所述预设温度小于加热器12的最大工作温度T1，即在t2时间点之前控制排热装置16启动工作以将加热产生的气溶胶沿着气体流动路径排出壳体10外。
在一示例中，电路14，被配置为在加热器12启动加热之后，对加热器12的加热时间进行计时；在加热器12的加热时间达到预设时间时，控制排热装置16启动工作以将加热产生的气溶胶沿着所述气体流动路径排出壳体10外。
其中，所述预设时间小于加热器12的温度从初始温度上升到最大工作温度的持续时间。即在t2时间点之前控制排热装置16启动工作以 将加热产生的气溶胶沿着气体流动路径排出壳体10外。
进一步地，在t10时刻，加热器12的加热温度T10使得烟支中的大部分水分均已蒸发，因此在t10时刻，即可控制排热装置16启动工作以将加热产生的热空气沿着气体流动路径排出壳体10外，这样可避免临近抽吸阶段时将加热产生的气溶胶沿着气体流动路径排出壳体10外，导致抽吸者在抽吸第一口时感觉烟雾量小、降低抽吸体验的问题。一般的，T10可以为80℃-200℃。
进一步地，电路14，还被配置为在抽吸者可对气溶胶生成装置100进行抽吸时，控制排热装置16停止工作。即在用户抽吸时(t4～t5期间)，排热装置16停止工作，此时用户即可抽吸到温度相对较低的烟气。
需要说明的是，排热装置16停止工作并不限于此种情形。例如：在排热装置16运行一段时间之后即停止工作，并不用等待抽吸者可对气溶胶生成装置100进行抽吸时才停止工作。很容易想象得到的，在排热装置16的工作期间，排热装置16的工作功率也是可调的，即可以一定的工作功率控制排热装置16运行一定的时间。
基于气溶胶生成装置100，本申请进一步提供一种气溶胶生成装置的控制方法，所述方法包括：
在加热器12启动加热之后至加热器12进入抽吸阶段之前，控制排热装置16启动工作以将加热产生的热空气沿着气体流动路径排出壳体10外；
其中，加热器12的温度变化曲线至少包括升温阶段和抽吸阶段。
图5是本申请实施例提供的气溶胶生成装置的控制过程示意图。气溶胶生成装置的控制过程包括步骤：
S31、在烟支插入腔室11之后，即可控制加热器12启动加热；
S32、获取温度传感器检测到的加热器12的温度信息；
S33、判断加热器12的是否大于或者等于预设温度？
S34、若加热器12的大于或者等于预设温度，则控制排热装置16启动工作；否则继续执行步骤S32(步骤S35)；
S36、排热装置16将加热产生的气溶胶沿着气体流动路径排出壳体10外；
S37、判断加热器12是否进入抽吸阶段？
S38、若加热器12进入抽吸阶段，则控制排热装置16停止工作；否则继续执行步骤S37(步骤S39)；
S40、用户开始抽吸。
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。
