具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请中的术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对于重要性或者隐含指明所指示的技术特征的数量或者次序。本申请实施例中所有方向性指示(诸如上、下、左、右、前、后……)仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系或者运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于 这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件，或者其间可能同时存在一个或者多个居中元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
请参照图1和图2，本申请的一实施例提供了一种气溶胶生成装置和适用于该气溶胶生成装置的加热模组，该气溶胶生成装置可用于加热气溶胶生成制品，可以使得气溶胶生成制品产生出气溶胶来，以供用户抽吸。
如本文所使用，术语“气溶胶生成制品”是指包括气溶胶形成基质的制品，当加热时，所述气溶胶形成基质释放出可形成气溶胶的挥发性化合物。所述气溶胶形成基质可以意图进行加热而不是燃烧来释放可形成气溶胶的挥发性化合物。相比于通过燃烧或热解降解气溶胶形成基质产生的气溶胶，通过加热气溶胶形成基质形成的气溶胶可含有更少的已知具有危害性的成分。在一实施例中，气溶胶生成制品可移除联接到气溶胶生成装置。气溶胶生成制品可为一次性的或可再用的。
气溶胶形成基质可为固体气溶胶形成基质。或者，气溶胶形成基 质可包括固体和液体组分。气溶胶形成基质可包括烟草。气溶胶形成基质可包括含烟草材料，所述含烟草材料能够在加热时释放出具有烟草香味或者具有尼古丁的化合物。气溶胶形成基质可包括非烟草材料。气溶胶形成基质可包括含烟草材料以及不含烟草材料。
气溶胶生成制品的外径可在大约5毫米和大约12毫米之间，例如在大约5.5毫米至大约8毫米之间。在一实施例中，气溶胶生成制品的外径为6.8毫米+/-10％。
气溶胶生成制品的总长度可在大约25mm至大约100mm之间。气溶胶生成制品的总长度可在大约30mm至大约100mm之间。
如本文中所使用，术语“气溶胶生成装置”是与气溶胶生成制品接合或交互以形成可吸入气溶胶的装置。具体的，请参照图1至图4，气溶胶生成装置包括加热模组1和本体2，加热模组1可以容纳气溶胶生成制品的至少局部，且加热模组1包含加热组件11，加热组件11可以释放热量，本体2可以包含电源组件21，电源组件21能够为加热组件11释放热量提供电力支持。其中，本体2包括支架23，加热模组1与支架23可移除地连接，从而加热模组1能够与支架23分离，因此可以在将加热模组1从支架23上移除后，对加热模组1进行清洁或者维护，甚至可以更换加热模组1。在一些示例中，将加热模组1从支架23上移除时，加热模组1同时脱离本体2。
较为具体的，加热模组1中设置有用于容纳气溶胶生成制品至少局部的第一容纳腔12，沿气流方向，加热组件11设置在第一容纳腔12的上游，加热组件11上具有允许空气通过的气孔111a，且加热组件11与第一容纳腔12流体连通，从而流经加热组件11的空气可以被加热组件11加热，形成热空气，热空气随后流入第一容纳腔12中，加热接纳于第一容纳腔12中的气溶胶生成制品，使气溶胶形成基质 产生气溶胶。
可以参照图2-图8，加热组件11包括有孔构件111，有孔构件111上具有流体连通第一容纳腔12的一个或者多个气孔111a，每一气孔111a毗邻第一容纳腔12的一端为出气端111c，相对的另一端则为进气端111b，沿气流的方向，进气端111b位于出气端111c的上游，空气通过进气端111b进入到相应的气孔111a中，然后通过出气端111c从该气孔111a中离开。
由于有孔构件111发生堵塞时主要是有孔构件111的进气端111b被堵塞，所以在将加热模组1从支架23上移除从而使得加热模组1脱离支架23时，可以对进气端111b进行清洁，即可疏通气孔111a，降低有孔构件111对吸阻的影响。
基于此，在一实施例中，在加热模组1从主体2或者支架23上移除时，至少部分气孔111a的进气端111b暴露，以方便对进气端111b进行清洁。其中，所述的“进气端暴露”是指进气端可以直接暴露在人眼的视野范围中，或者是指在不对加热模组进行拆解时清洁工具可以触及和清洁进气端，甚至清洁工具能够伸入到气孔111a中。在加热模组1从主体2或者支架23上移除后，有孔构件111上的进气端111b是未被遮挡的、裸露在加热模组1上的。在一示例中，在加热模组1从主体2上移除时，有孔构件111上的所有气孔111a的进气端111b均暴露，从而能够对每一气孔111a的进气端111b进行清洁和对每一气孔111a进行疏通，因此有助于降低加热模组1作为整体的更换率，对降低使用成本和节省社会资源有益。
在一实施例中，可以参照图2，加热模组1还包括端盖13，端盖13上具有供气溶胶生成制品插入第一容纳腔12的插入口131，端盖13的至少局部从本体2或者支架23上暴露，从而可以通过作用于端 盖13来使加热模组1脱离本体2或者支架23。所述的“端盖的至少局部从本体或支架上暴露”是指端盖的至少局部可以直接暴露在人眼的视野范围中，或者是指在不对气溶胶生成装置进行拆解(除移除遮挡端盖的防尘盖之外的拆解)时，用户或者治具可以触及和/或施力于端盖。有助于方便将加热模组1从本体2或支架23上移除。
作为一种示例，可以参照图3和图6，端盖13包括沿第一容纳腔12的径向延伸的盖部132，盖部132位于气溶胶生成装置的上端，且盖部132的至少局部布置在本体2或支架23的上方并被本体2或支架23支撑。从而盖部132从本体2或支架23上暴露，可以通过作用于盖部132来将加热模组1从本体2或支架23上移除，可以沿第一容纳腔12的轴向使加热模组1与本体2或支架23结合或者使加热模组1从本体2或支架23上移除。其中，插入口131的至少局部边界可以由盖部132界定。
作为一种示例，可以参照图3和图6，端盖13包括沿第一容纳腔12的轴向延伸的管部133，管部133可以界定插入口131的至少局部，管部133与第一容纳腔12连通，管部133可以将气溶胶生成制品导向第一容纳腔12中。管部133的至少局部可以夹持气溶胶生成制品，以防止用户在抽吸气溶胶生成制品时，气溶胶生成制品被用户的嘴部带出气溶胶生成装置。
在如图5和图8所示的实施例中，管部133与盖部132独立成型，然后通过组装连接，管部133和盖部132分别界定插入口131的一部分边界。在其他实施例中，管部133与盖部132可以一体成型。
作为一种示例，可以参照图3，气溶胶生成装置内具有与加热组件11流体连通的气流通道4，端盖13可以提供气溶胶生成装置外界的空气进入气流通道4的进气通道，从而气溶胶生成装置外界的空气 可以依次通过端盖13、气流通道4和加热组件11进入第一容纳腔12中。
例如，可以在管部133的壁上开设流体连通插入口131和气流通道4的通孔1334，从而气溶胶生成装置外界的空气可以依次通过插入口131和通孔1334进入气流通道4中。
基于此，可以参照图5，管部133可以包括第一部分1331和第二部分1332，第一部分1331和第二部分1332可以沿第一容纳腔12的轴向分布，第一部分1331的内径可以大于第二部分1332的内径，通孔1334开设在第一部分1331上，从而在气溶胶生成制品插入至插入口131时，能够防止通孔1334被气溶胶生成制品堵塞，有助于降低吸阻。更为具体的，第二部分1332的内径可以小于或者等于气溶胶生成制品的外径，从而第二部分1332能够夹紧气溶胶生成制品，防止用户在气溶胶生成制品在不期待的情况下相对气溶胶生成装置移动。沿气流的方向，第一部分1331设置在第二部分1332的上游，第一部分1331的内径可以大于气溶胶生成制品的外径，第一部分1331可以毗邻盖部132或者毗邻气溶胶生成装置的外界设置，相比第二部分1332，第一部分1331更加靠近盖部132或者更加靠近外界。
管部133上还可以具有位于第一部分1331和第二部分1332之间的第三部分1333，第三部分1333的内径大于第二部分1332的内径，同时第三部分1333的内径小于第一部分1331的内径，第三部分1333内壁的至少局部可以形成坡面，坡面有助于气溶胶生成制品在穿过第一部分1331后能够较为容易地进入第二部分1332中，从而有利于将气溶胶生成制品插入第一容纳腔12中。
在一实施例中，可以参照图4、图5、图7和图8，加热模组1还包括连接件14，连接件14连接加热组件11，在加热模组1与本体 2或支架23结合时，加热组件11通过连接件14被送入本体2或支架23中，在加热模组1从本体2或支架23上移除时，加热组件11通过连接件14被带出本体2或支架23。
可以参照图3-图8，连接件14环绕第一容纳腔12设置，气溶胶生成制品的至少局部可以保持在连接件14中。其中，连接件14可以连接加热组件11和端盖13，从而使得加热组件11可以与端盖13相对本体2同步运动。更为具体的，连接件14可以连接管部133和加热组件11。
基于此，作为一个示例，连接件14包括第一连接件141，第一连接件141界定第一容纳腔12的至少局部边界，在气溶胶生成制品插入第一容纳腔12时，第一连接件141内壁的至少局部可以接触气溶胶生成制品。
可以使第一连接件141至少局部的内径小于气溶胶生成制品的外径，或者可以使第一连接件141至少局部的内径略小于第二部分1332的内径，从而第一连接件141的至少局部能够夹持气溶胶生成制品，有助于使得气溶胶生成制品能够更加稳定地保持在加热模组1中。
可以使第一连接件141至少局部的内径大于气溶胶生成制品的外径，以方便气溶胶生成制品在加热模组1中插拔。
基于此，可以参照图8，第一连接件141可以包括第四部分141a和第五部分141b，相比第五部分141b，第四部分141a更加靠近端盖13，甚至第四部分141a能够连接端盖13。第四部分141a的内径小于气溶胶生成制品的外径，或者第四部分141a的内径小于第二部分1332的内径，第四部分141a能够夹持气溶胶生成制品。
沿气流的方向，第五部分141b位于第四部分141a的上游，所以 被加热组件11加热的空气在沿气流方向流动并释放热量时，第五部分141b的温度会高于第四部分141a的温度，同时被第五部分141b环绕的气溶胶生成制品的温度可能会高于被第四部分141a环绕的气溶胶生成制品的温度。为了防止被第五部分141b环绕的气溶胶生成制品过热，可以使第五部分141b的内径大于气溶胶生成制品的外径，从而在气溶胶生成制品容纳在第一容纳腔12时，第五部分141b与气溶胶生成制品之间无接触，并且第五部分141b与气溶胶生成制品之间的空气能够形成空气隔热层，有助于防止被第五部分141b环绕的气溶胶生成制品被烤糊。
为了降低第一连接件141上的温度梯度和确保被第一连接件141环绕的气溶胶生成制品受热均匀，可以使第一连接件141由导热材料制成。导热材料可以理解为在23℃及50％的相对湿度下热导率是至少10W/(m·k)，优选的是至少40W/(m·k)，更优选的是至少100W/(m·k)的材料。具体的，第一连接件141由在23℃和50％的相对湿度下热导率是至少40W/(m·k)，优选的是至少100W/(m·k)，更优选的是至少150W/(m·k)，并且最优选的是至少200W/(m·k)的材料形成。合适的导热材料包含但不限于：石墨、石墨烯、铝、铜、锌、钢、银、导热聚合物、金属或其任何组合或合金。
采用导热材料制备第一连接件141，能够使被第一连接件141环绕的气溶胶生成制品内部的上下游均能够被充分地加热，有助于使气溶胶生成制品被充分地利用，和有利于提升抽吸口感。
作为一个示例，第一连接件141连接加热组件11和端盖13。例如，可以参照图4和图5，第一连接件141被构造成空心的管状，第一连接件141的内部可以具有流体连通的第一容纳腔12和第三容纳腔，第一容纳腔12用于接纳气溶胶生成制品的至少局部，加热组件 11的至少局部设置在第三容纳腔中。
作为一个示例，连接件14在包括第一连接件141的基础上，还可以包括第二连接件142，第二连接件142连接第一连接件141和加热组件11。例如，可以参照图7和图8，第二连接件142被构造成空心的管状，第一连接件141的至少局部可以设置在第二连接件142中，加热组件11的至少局部设置在第二连接件142中。在此示例中，加热组件11与第一连接件141之间可以无接触，当然也不排除加热组件11可以与第一连接件141连接的示例。
第二连接件142可以对第一容纳腔12的至少局部进行隔热，以减缓被加热组件11加热的空气在气溶胶生成制品内部温度下降的速度，有助于降低气溶胶生成装置的能耗，和有益于使气溶胶生成制品受热更加充分。
第二连接件142可以采用隔热材料制成，隔热材料是指材料的导热性在23℃和50％的相对湿度下小于100W/(m·K)，优选的是小于40W/(m·K)或小于10W/(m·K)。例如，隔热材料可以包含PAEK类材料、PI材料或者PBI材料中的至少一种制成，其中，PAEK类材料包括PEEK、PEKK、PEKEKK或PEK材料。例如，隔热材料可以包括玻璃纤维、玻璃毡、陶瓷、二氧化硅、氧化铝、碳和矿石，或其任何组合。
或者，第二连接件142中可以具有密闭的空气夹层，该密闭的空气夹层可以是负压层(气压小于大气压)，或者可以是常压层(气压等于大气压)。
作为一个示例，可以参照图6和图8，连接件14包括第二连接件142和第三连接件143，加热组件11的至少局部设置在第三连接件143内，第二连接件142连接端盖13和第三连接件143。在此示 例中，加热模组1中可以无第一连接件141。或者在此示例中，请参照图6-图8，加热模组1中可以仍然具有第一连接件141。
其中，第三连接件143能够耐受300℃及以上的高温，第三连接件143可以采用隔热材料制成，或者第三连接件143可以采用高热容量的材料制成。其中，高热容量的材料可以是在25℃和恒定压力下比热容是至少0.5J/(g·K)，例如至少0.7J/(g·K)，例如至少0.8J/(g·K)的材料。例如第三连接件143可以包含但不限于玻璃纤维、玻璃毡、陶瓷、二氧化硅、氧化铝、碳和矿石，或其任何组合。
在同时具有第一连接件141和第二连接件142时，可以使第一连接件141和第二连接件142二者中的至少一者与端盖13连接。在如图6和图8所示的实施例中，第一连接件141和第二连接件142均与端盖13连接，具体的，第一连接件141和第二连接件142均与管部133连接。
其中，第一连接件141和第二连接件142之间可以具有间隙15，第一连接件141与管部133之间的连接可以为间隙连接，从而插入口131中的空气可以通过第一连接件141与管部133之间的连接间隙进入第一连接件141和第二连接件142之间的间隙15中，因此可以在第一连接件141和第二连接件142之间形成空气保温层，该空气保温层至少环绕第一连接件141的第四部分141a。沿空气进入第一连接件141和第二连接件142之间的间隙15的方向，管部133的第二部分1332位于第一连接件141与管部133之间的连接间隙的上游，可以使第二部分1332紧贴气溶胶生成制品至少一周，从而第二部分1322与气溶胶生成制品相互配合能够阻止空气进入第一连接件141与管部133之间的连接间隙，进而阻止空气进入第一连接件141和第二连接件142之间的间隙15，以此使得在气溶胶生成制品结合在加 热模组1中时，第一连接件141和第二连接件142之间的空气隔热层(间隙15)属于封闭状态，以降低该空气隔热层中的对流，增加该空气隔热层的保温隔热效果。需要说明的是，第一连接件141和第二连接件142之间的空气隔热层是可选而非必选的。
在加热模组1中具有第一连接件141时，加热组件11的至少局部可以设置在第一连接件141之外。在如图6和图8所示的实施例中，加热组件11完全位于第一连接件141之外。
而在如图3和图5所示的实施例中，加热组件11几乎完全位于第一连接件141之内。
有孔构件111包括上游端111d和下游端，进气端111b开设在上游端111d，出气端111c开设在下游端。以插入口131位于气溶胶生成装置的上端为位置参照，连接件14的下端是敞开的，从而有孔构件111的上游端111d和开设在上游端111d上的进气端111b暴露。在图4和5所示的实施例中，上游端111d凸伸至连接件14之外，从而有孔构件111的上游端111d和开设在上游端111d上的进气端111b暴露。可以理解的是，还可以通过使上游端111d与连接件14的下端平齐，或者如图7和图8所示，使上游端111d位于连接件14的内部且上游端111d与连接件14的下端之间具有间隔等方式来暴露上游端111d和开设在上游端111d上的进气端111b。
需要说明的是，通过作用于端盖13使加热模组1可从本体2或支架23上移除是可选而非必选的，还可以通过将力施加在加热模组1的其他部位来驱使加热模组1从本体2或支架23上移除，称该其他部件为受力部件，连接件14可以连接该受力部件和加热组件11。
在一实施例中，加热组件11包括可在变化磁场中发热的感受器16。当在本文中使用时，术语“感受器”是指可以将电磁能量转换成 热的材料。当位于变化的电磁场内时，在感受器16中引起的涡电流和磁滞能够引起感受器16的加热。在此类实施例中，感受器16被设计成与包括磁场发生器22的气溶胶生成装置接合。磁场发生器22生成变化的磁场，以加热位于变化的磁场内的感受器16。在使用时，感受器16位于由磁场发生器22生成的变化的磁场内。其中，磁场发生器22与电源组件21电连接，电源组件21为磁场发生器22提供产生变化的磁场的电流。磁场发生器22可包括生成变化的磁场的一个或多个感应线圈，一个或多个感应线圈可围绕感受器16。在一实施例中，气溶胶生成装置能够生成在1至30MHz之间，例如在2至10MHz之间，例如在5至7MHz之间的变化的磁场。在一实施例中，气溶胶生成装置能够生成具有在1至5kA/m之间，例如在2至3kA/m之间，例如为约2.5kA/m的场强(H场)的变化的磁场。
其中，感受器16可以包括金属或碳。在一实施例中，感受器16可包括铁磁性材料，例如铁素体、铁磁性钢或不锈钢。在一实施例中，感受器16包括镍铁合金。在一实施例中，感受器16包括400系列不锈钢，400系列不锈钢包括410级或420级或430级不锈钢。其中碳包括石墨、石墨烯或石墨合金等。
作为一个示例，有孔构件111的至少局部由感受器16构成，即至少部分气孔111a可以开设在感受器16上。
作为一个示例，可以参照图5和图8，感受器16结合在有孔构件111上，有孔构件111通过吸收感受器16释放的热量升温，然后有孔构件111再释放热量加热流经气孔111a的空气。基于此，有孔构件111可以采用导热材料例如石墨、石墨烯、石墨合金或金属等制成。或者，有孔构件111可以采用高热容量的材料制成。
在感受器16结合在有孔构件111上时，感受器16的至少局部可 以嵌入在有孔构件111中，或者感受器16可以环绕有孔构件111设置。
磁场发生器22可以结合在加热模组1上，从而磁场发生器22能够随加热模组1一起从本体2或支架23上移除。在磁场发生器22结合在加热模组1上时，加热模组1还包括与磁场发生器22电连接的第一电极，本体2或支架23上则设置有与电源组件21电连接的第二电极，在加热模组1结合在本体2或支架23上时，第一电极与第二电极抵接，从而第一电极能够从第二电极上取电，进而为磁场发生器22提供产生变化的磁场的电能；其中，第一电极与第二电极之间的抵接是可分离的，从而不影响将加热模组1从本体2或支架23上移除。
需要说明的是，在其他实施例中，加热模组1包括第一电极，加热组件11包括与第一电极电连接的电阻加热元件，本体2或支架23包括第二电极，在加热模组1结合在本体2或支架23上时，第一电极与第二电极抵接，从而第一电极能够从第二电极上取电，进而为电阻加热元件提供产生焦耳热的电能，在该实施例中，加热模组1可以未包含感受器16；其中，第一电极与第二电极之间的抵接是可分离的，从而不影响将加热模组1从本体2上移除。
可以参照图5和图8，磁场发生器22可以结合在本体2或支架23上，从而加热模组1从本体2或支架23上移除时，磁场发生器22能够保留在本体2或支架23上。在加热模组1结合在本体2或支架23上时，加热组件11的至少局部例如感受器16处于磁场发生器22的磁场覆盖范围中。
在加热模组1结合在本体2或支架23上时，作为一个示例，请参照图3、图5、图6和图8，支架23的内部形成有第二容纳腔231， 加热模组1的至少局部接纳在第二容纳腔231中，在加热模组1从支架23上移除时，加热模组1脱离第二容纳腔231。支架23可以隔绝磁场发生器22和第二容纳腔231，以防止第二容纳腔231中的气溶胶、冷凝液等粘附在磁场发生器22上，从而保护磁场发生器22。例如，第二容纳腔231位于支架23的内侧，磁场发生器22包括感应线圈，感应线圈绕制在支架23的外侧。
需要说明的是，无论本体2上是否结合有磁场发生器22，本体2均可以包括能够形成第二容纳腔231的支架23。
在一实施例中，以插入口131位于气溶胶生成装置的上端为位置参照，支架23包括布置在加热模组1下方的第一支架232，第一支架232的至少局部可以沿第一容纳腔12的径向延伸，第一支架232的至少局部可以界定第二容纳腔231底部的至少部分边界。其中，加热组件11与第一支架232相互间隔，从而漫延至有孔构件111进气端111b的液体不会因为第一支架232而保持在进气端111b，进而堵塞气孔111a或影响空气进入气孔111a。有利于使气孔111a尽快排出其内的液体，防止气孔111a堵塞。可以将加热模组1从本体2上移除，然后清理第一支架232上积累的液体和油垢，防止第一支架232和有孔构件111通过液体连接，和防止第一支架232上的液体太过接近甚至浸没孔构件111的上游端111d。
可以使进气端111b与第一支架232仅通过空气间隔，即，可以如图3和图6所示，进气端111b与第一支架232之间无其他结构构件，或者在沿第一容纳腔12的轴向向下的正投影中，设置在加热模组1与第一支架232之间的其他构件的投影位于全体气孔111a的正投影的外围，并且连接加热组件11的连接件14也不会延伸至进气端111b与第一支架232之间，在沿第一容纳腔12的轴向向下的正投影 中，连接件14的正投影未与任一气孔111a的正投影有重叠。以防止液体在进气端111b和连接件14之间积累和形成油垢至堵塞气孔111a，和防止液体在进气端111b和第一支架232之间积累和形成油垢至堵塞气孔111a。
作为一个示例，可以参照图5和图8，第一支架232密封第二容纳腔231的底部，从而第二容纳腔231的侧壁上的冷凝液和有孔构件111中的液体可以汇集在第一支架232上，第一支架232能够防止气溶胶生成装置泄漏液体。同时，第一支架232还能够隔绝电源组件21和第二容纳腔231，防止气溶胶污染和腐蚀电源组件21，对保护电源组件21有益。
第一支架232密封第二容纳腔231的底部，且第一支架232与进气端111b通过空气相间隔，可以使得第一支架232与加热模组1之间形成有空气隔热层，对防止加热组件11温度降低有益，并有利于降低气溶胶生成装置的能耗。
在如图5和图8所示的实施例中，第一支架232背离第二容纳腔231的一侧形成空腔24，该空腔24内可以形成有空气隔热层，从而进一步对加热组件11和第二容纳腔231进行保温。其中，空腔24的至少局部边界可以由第一支架232界定。
作为一个示例，可以参照图5和图8，支架23在包括第一支架232的基础上，还包括第二支架233，第二支架233沿第一容纳腔12的轴向延伸且界定第二容纳腔231的局部边界。第二支架233可以是完整的，其侧壁上可以未开设连通第二支架233内外两侧的贯通孔。气流通道4的至少局部可以设置在第二支架233与加热模组1之间。从而空气在进入加热组件11的气孔111a之前，先沿加热模组1的外壁流动，从而对进入气孔111a的空气进行预热，有助于充分利用加 热组件11释放的能量，还能够防止气溶胶生成装置的表面温度过高。
其中，第一支架232和第二支架233可相互组装连接，或者第一支架232和第二支架233可以一体成型。
上述的气溶胶生成装置及加热模组1，可以容纳气溶胶生成制品至少局部的加热模组1包含能够加热空气的加热组件11，加热模组1与本体2可移除地连接，且在加热模组1被移除时，加热组件11上的至少部分气孔111a的进气端111b暴露，从而可以在加热组件11被堵塞时，更换加热模组1，或者在移出加热模组1后，清洁暴露的进气端111b，疏通气孔111a。
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。
