发明内容

上述的加热器、加热组件、加热模组及气溶胶产生装置，通过将第一温度检测器的探测部设置在安装孔内，来实现将探测部设置在基体的内部，从而第一温度检测器能够检测基体内部的温度变化，相比检测基体表面的温度，检测内部的温度既能降低基体表面与基体内部之间的温度梯度引起的检测误差，又能不受设置在加热器外围的保温层影响。具体的，将探测部设置在安装孔中，空气流经第一气孔时会先降低基体内部的温度，尤其在用户频繁抽吸导致空气流速、流量大增时，探测部能够实时且敏感地检测到基体由于气流变化引起的温度变化，从而提供更加准确且及时的温度参数；同时也对气溶胶产生装置的 温控十分有利。

在一实施例中，加热体3含有等级430的不锈钢(SS430)，或含有等级420的不锈钢(SS420)，或含有铁镍的合金材料(比如坡莫合金)，或含有石墨合金等可在变化的磁场中发热的磁感性材料，加热体3在变化的磁场中因为产生涡电流和磁滞等而自发热，并加热流经的空气，进而利用空气加热气溶胶生成制品1。相应的，气溶胶产生装置还包括磁场发生器5，例如感应线圈，用于在交变电流下产生变化的磁场，且控制器42连接电芯41和感应线圈，并且可将电芯41输出的直流电流转化为交变电流，优选该交变电流的频率介于80KHz～400KHz；更具体地，所述频率可以在大约200KHz到300KHz的范围。

在一优选的实施中，基体31和固定部32二者至少之一由铁铬铝合金、镍铬合金、镍铁合金、铂、钨、银、导电陶瓷等电阻性导电材料制成，或者包含上述至少其一的导电材料，从而在导电时可以通过电阻的电热效应发热，来加热气溶胶生成制品1，使气溶胶生成制品1中的至少一种成分挥发，形成气溶胶。
在一优选的实施中，加热器3中的固定部32与基体31可以由同一种材料一体成型，如由石墨合金粉末等磁感性材料一体成型。
在一优选的实施中，基体31和固定部32二者至少之一可以发热。若基体31和固定部32中仅一者可以发热，则另一者通过热传递升温，然后加热流经的空气。
在一优选的实施中，基体31和固定部32二者至少之一包括导热体和发热体，发热体可以利用电热效应发热，或者利用电磁感应发热，或者利用红外辐射加热导热体等，导热体上具有上述的第一气孔33或者空气可流经导热体，并且在空气流经导热体时可与导热体发生热交换，进而被加热成热空气。具体的，至少部分加热体可以设置在导热体的外围，如加热体为设置在导热体的外表面的电阻膜、电热丝、磁感应环、导电陶瓷环等，在其他实施例中，至少部分加热体还可以设置在导热体的内部，如设置在第一气孔33的壁上等，从而加热体可以直接或者间接地加热流经的空气。在本实施例中，由于基体31被一个或者多个第一气孔33贯穿，因此具备第一气孔33的导热体被第一气孔33贯穿。
在一优选的实施中，基体31与固定部32为由同种材料一体成型制成的一体结构，从而单位面积或者单位体积的基体31与固定部32具有大致相同的加热效率；在其他实施例中，基体31与固定部32为由不同种材料一体成型制成的一体结构，从而单位面积或者单位体积的基体31与固定部32具有不尽相同的加热效率，从而可以根据流经不同区间的空气的不同温度需求设置固定部32的位置，或者可以根据加热器3的散热趋势等，设置固定部32的位置。当然，不排除固定部32可以与基体31分体成型，然后再相互连接的可能。
在一实施例中，可参照图3和4，基体31的侧表面包括第一表面311和第二表面，第一表面311和第二表面沿加热器3的轴向分布，且沿空气流动的方向，第二表面位于第一表面311的下游。固定部32设置在基体31的侧表面，在一个实施例中，固定部32仅占据基体31侧表面的局部区域，具体的，固定部32可以设置在第一表面311；或者，固定部32可以设置在第二表面(如图3和4所示)；或者，固定部32连接第一表面311和第二表面，且占据第一表面311的局部，同时占据第二表面的局部。当然在另一实施例中，固定部32连接第一表面311和第二表面，且固定部32沿加热器2轴向的长度可以不小于第一表面311和第二表面沿加热器3轴向长度之和。
在一些可选的实施例中，第一表面311和第二表面的轮廓均为圆形，在其他可选的实施例中，第一表面311的轮廓可以为方形、椭圆形、三角形等规则图形或者不规则图形，第二表面的轮廓也可以为各种规则图形或者不规则图形中的一种，其可以与第一表面的轮廓一致，也可以不一致。
在一实施例中，可参照图3-5，固定部32的侧表面凹陷形成凹槽341，凹槽341形成供空气通过的气道。凹槽341的槽底距离基体31中心轴的距离可以大于基体31的相应单边到基体31中心轴的距离，从而流经凹槽341的空气会与固定部32接触而发生热交换，进而被固定部32加热。可以理解的是，在一些实施例中，基体31的局部表面可以构成凹槽341的槽底，从而流经凹槽341的空气会与固定部和基体31接触而发生热交换，进而被固定部32和基体31的外表面加热。
在进一步的实施例中，凹槽341可以为沿加热器的轴向延伸的直线形；在另一实施例中，凹槽341可以为贯穿固定部32近端和远端的蛇行形或者折线形；在另一实施例中，凹槽341可以为贯穿固定部32的斜线形或者弧线形或者螺旋形等。
本说明书各实施例中所说的“近端”和“远端”是相对于使用者在使用时而言的，"近端"是指靠近使用者的一端，"远端"是指远离使用者的一端，不用来限度本申请。
在进一步的实施例中，同一凹槽341各处的槽宽相同，从而空气在凹槽341各处与凹槽341具有大致相同的接触面积，进而具有大致相同的换热效率。
凹槽341可以有且仅有一个。优选，固定部32上的凹槽341具有多个，这些凹槽341均匀地分布在固定部31上，从而流经固定部32的空气能够被均匀地加热，这里所述的均匀地分布包括：1、所有的凹槽341可以具有大致相同的尺寸和形状；2、在加热器3的同一轴向高度上，相邻两凹槽341之间的间距与其他任意相邻两凹槽341之间的距离相同。
在更进一步的实施例中，可以参照图3-6，固定部32构成环绕基体31设置的环形，从而使得固定部32上形成的凹槽341呈环形地分布在基体31的外围，且可以是均匀地分布。
而在有些实施例中，固定部上的多个凹槽341的分布可以不均匀。当然，固定部32可以不构成环形，而是设置在基体31表面的一个或者多个块状体或者弧形体，凹槽341设置在块状体或者弧形体的表面。
在一实施例中，可参照图6，固定部32被第二气孔342沿加热器3的轴向贯穿，第二气孔342形成供空气通过的气道的至少局部。同上，第二气孔342可以具有多个，多个第二气孔342可以均匀或者不均匀地分布在固定部32中，固定部32可以构成环绕基体31的环形，或者固定部32为设置在基体31侧表面的块状体或者弧形体。空气通过第二气孔342时，与固定部32接触，从而与固定部32发生热交换，而被加热。当第二气孔342的局部孔壁由基体31界定时，则第二气孔342中的空气还可以被基体31加热。第二气孔342的孔径可以小于第一气孔33的孔径。
在一实施例中，可参照图7，固定部32具有多个，至少具有两个，相邻两固定部32之间形成有供空气通过的气道的至少局部。从而，空气通过该气道时，同时被固定部32和基体31接触而同时被双方加热。
可以理解的是，固定部32是可选项，不是必选项。
为了方便控制器42对加热器3进行温控，在如图2和8所示的实施例中，加热器3还包括安装孔36和第一温度检测器35，第一温度检测器35安装在安装孔36中，通过第一温度检测器35来检测加热器3的温度，然后控制器42获取该温度数据，进而分析该温度数据，最后对加热器3进行温度控制。
由于空气从加热器3内部流经时，会带走加热器3内部的热量，导致加热 器3内部的温度变化，而加热器3的侧壁外表面在空气通过加热器3内部时温度变化不明显，引起这种不明显的原因可能是多重的，包括：1、加热器3的外围具有保温层，保温层使得加热器3的外表面温度较为稳定；或者2、加热器主要通过其表层进行发热，从而其在工作时能够使表层温度较为恒定，而不受其内部温度变化的影响等。为了第一温度检测器35设置在加热器表面带来的温度检测问题，本申请采用将第一温度检测器35设置在加热器3的内部，来代替现有的将第一温度检测器设35置在加热器3的表面。
可以参照图8，安装孔36设置在基体31的内部，第一温度检测器35的探测部可以设置在安装孔36中，从而可以检测基体31内部的温度。
在一实施例中，安装孔36为盲孔，设置在基体31内部却未贯穿基体31，或者安装孔36为至少一端被封堵的通孔，导致空气不能穿过安装孔36，但由于安装孔36设置在基体31的内部，第一温度检测器35的探测部设置在安装孔36的内部，在空气通过第一气孔33导致基体31内部温度变化时，第一温度检测器35也能够较为直观和准确地捕获基体31内部的温度，进而记录或者反映基体31内部的温度。
在一实施例中，安装孔36为贯穿基体31的通孔，且在安装第一温度检测器35后，空气仍可通过该安装孔36，使得在抽吸时，空气能够通过安装孔36与第一气孔33，使得安装孔36与第一气孔33具有大致相同的温度变化程度，从而使得第一温度检测器35在安装孔36中获得基体31的温度数据更接近第一气孔33的实际温度，更具有参考价值。或者，安装孔36由其中一第一气孔33构成，从而位于该第一气孔33中的第一温度检测器35可以检测当空气流经时，该第一气孔33的温度。
在一实施例中，固定部32的一气道构成安装孔36，从而位于安装孔36中的第一温度检测器35可以检测当空气流经气道时，该气道的温度。
传统的，第一温度检测器35设置在加热器的表面，当因抽吸导致空气快速地流经加热器的气孔或气道时，气孔或气道因与温度较低的空气直接接触而导致其温度会较大幅度地降低，但是，加热器的表面，如基体的表面，因未与冷空气直接接触，所以在抽吸时，在短时间内加热器表面的温度变化相对而言并不明显，从而导致第一温度检测器35的检测灵敏度较低。
采用本申请的方案，能够直接、快速、及时地获得第一气孔33或气道中空气的温度，从而能够更加准确的获取空气的温度数据，检测灵敏度高且该温度数据有利于控制器42及时且准确地对加热器3进行温控，能够及时阻止温度过高而烤糊气溶胶生成制品1，或者能够及时对提高对加热器3的功率供应，使得加热器3快速恢复满足当下抽吸的目标温度，或者恢复满足下一口抽吸要求的目标温度，有助于提高用户体验。
在一优选的实施例中，第一温度检测器35设置在基体31的中心区域中，如安装孔36设置在基体31的正中心。当然，也可以偏离正中心设置在气流密集区域或者设置在气流流量大的区域，因为正中心、气流密集区域或气流流量大的区域温度变化相较而言更加剧烈，且更能反映加热器3的实际应采集温度。
在一优选的实施例中，安装孔36有且仅有一个，第一温度检测器35也可以有且仅有一个，当然，第一温度检测器35可以具有多个，且其探测部均设置在该安装孔36中，优选多个不同的第一温度检测器35的探测部设置在该安装孔36中的不同位置处，如设置在安装孔36不同的轴向深度上等。
在一优选的实施例中，安装孔36可以具有多个，第一温度检测器35随之亦可以具有多个，分别设置在多个不同的安装孔36中，如设置在不同安装孔36中的相同轴向深度处等，从而可以根据多个第一温度检测器35获取的加热器3温度数据了解加热器3的温度分布信息，或者了解加热器3内部的实时的平均温度数据，有助于实现控制器42对加热器3更加准确的温度控制。
为了方便安装第一温度检测器35，或者为了不影响空气从安装孔36中通过，优选安装孔36的孔径大于无需安装第一温度检测器35的第一气孔33的孔径，当然，也不排除安装孔36的孔径与第一气孔33的孔径相同的可能。
请参照图8，无论安装孔36为允许空气通过的孔，还是不允许空气通过的孔，安装孔36外围都可以分布多个第一气孔33，包括被多个第一气孔33环绕，或者多个第一气孔33包围安装孔36的至少局部，从而使安装孔36在抽吸时或自然对流下处于被气流至少局部环绕的位置，或者处于气流密集区域的中心或者边缘，从而使得其周围多个第一气孔33温度的变化对安装孔36的温度变化具有较大的影响。优选安装孔36被多个第一气孔33均匀地环绕，以使安装孔36内的温场分布较为均匀，使第一温度检测器35获取的温度数据更加可靠。
优选，第一温度检测器35的探测部位于安装孔36轴向长度的中间。
在一实施例中，可以参照图3和4，第一温度检测器35包括第一热电偶线351和第二热电偶线352。
在一优选的实施例中，基体31的至少局部由导电材料构成，优选该导电材料设置在安装孔36中。第一热电偶线351和第二热电偶线352通过该导电材料实现相互电连接，从而构成检测基体31温度的热电偶，其中，该导电材料构成热电偶的探测部。
同理，在另一优选的实施例中，固定部32的至少局部由导电材料构成，优选该导电材料设置在气道中，第一热电偶线351和第二热电偶线352通过该导电材料实现相互电连接，从而构成检测固定部32温度的热电偶，其中，该导电材料构成热电偶的探测部。
在进一步的实施例中，整个基体31由导电材料制成，和/或者全部固定部32由导电材料制成。
在一优选的实施例中，第一热电偶线351和第二热电偶线352位于同一安装孔36中。当然，不排除第一热电偶线351和第二热电偶线352可以位于不同的安装孔36中，优选安装孔36比未容纳电偶线的第一气孔33的孔径大，从而空气能够通过安装孔36，或者方便将第一热电偶线351和第二热电偶线352的至少局部设置在安装孔36中。
在一优选的实施例中，第一热电偶线351和第二热电偶线352分别采用不同的电偶丝材质制备，例如，第一热电偶线351和第二热电偶线352分别是采用镍、镍铬合金、镍硅合金、镍铬-考铜、康青铜、铁铬合金等电偶材料中的两种不同材质制备的。即第一热电偶线351和第二热电偶线352由不同的材料制成。
在一实施例中，可以参照图4，第一温度检测器35埋设在基体31或固定部32的内部，具体的，第一温度检测器35的探测部可以设置在第一气孔33中，或者设置在固定部32的第二气孔342上，从而可以检测当空气流经第一气孔33或第二气孔342时该第一气孔33或第二气孔342的温度，进而能够更加准确地获取被加热的空气的温度，第一气孔33或第二气孔342中空气温度的变化能够 较为及时和直地被第一温度检测器35捕获。传统的，第一温度检测器35设置在加热器3的表面，当因抽吸导致空气快速地流经加热器3的第一气孔33或第二气孔342时，第一气孔33或第二气孔342因与温度较低的空气直接接触而导致其温度会较大幅度地降低，但是，加热器3的表面，如基体31的表面，因未与冷空气直接接触，所以在抽吸时，加热器3表面的温度变化相对而言并不明显，从而导致第一温度检测器35的检测灵敏度较低。采用本申请的方案，能够直接、快速、及时地获得第一气孔33或第二气孔342中空气的温度，从而能够更加准确的获取空气的温度数据，检测灵敏度高且该温度数据有利于控制器42及时且准确地对加热器3进行温控，能够及时阻止温度过高而烤糊气溶胶生成制品1，或者能够及时对提高对加热器3的功率供应，使得加热器3快速恢复满足当下抽吸的目标温度，或者恢复满足下一口抽吸要求的目标温度，有助于提高用户体验。
上述的加热器及气溶胶产生装置，通过将第一温度检测器35的探测部设置在安装孔内，来实现将探测部设置在基体的内部，从而第一温度检测器35能够检测基体内部的温度变化，相比检测基体表面的温度，检测内部的温度既能降低温度梯度引起的检测误差，又能不受设置在加热器外围的保温层影响。将探测部设置在安装孔中，空气流经第一气孔时会降低基体内部的温度，从而在用户因抽吸导致空气流速、流量大增时，探测部能够实时且敏感地检测到基体由于气流变化引起的温度变化，从而提供更加准确且及时的温度参数，这对加热器进行温控十分有益。
在一实施例中，可以参照图9，其中一加热器3包括第一部分37和第二部分38，第一部分37和第二部分38被一个或者多个第一气孔33同时贯穿，第一气孔33允许空气通过，且空气在通过第一气孔33时，能够被加热器3加热成热空气，热空气用于进入气溶胶生成制品1中，通过流经气溶胶生成制品1内部的几乎所有空隙，从而可以充分且均匀地烘烤气溶胶生成制品1。
在一实施例中，还提供一种加热组件，可以参照图10，加热组件包括加热器3和管状体6，管状体6为管状，其上下两端贯通，空气可从其下端流向其上端。加热器3的局部与管状体6相嵌固定，加热器3通过管状体6保持在气溶胶产生装置的容纳腔中。
在一实施例中，管状体6为电磁加热体、电阻加热体、红外加热体或者保温管等。
在一实施例中，可以参照图10，第二气孔342还可以由管状体6与第二部分38共同界定，空气可以通过第二气孔342进入气溶胶生成制品1中，且空气在通过第二气孔342时，至少被第二部分38加热，从而形成热空气。
在一实施例中，第二气孔342可以均匀地分布，包括个第二气孔342具有相同的孔径，任意相邻两第二气孔342之间具有相同的距离，每一第二气孔342各处孔径相同等。但是不以此为限，即第二气孔342可以不均匀地分布。当然，第二气孔342可以是直线形的，也可以是弯曲或者弯折的。
在一可选的实施例中，可以参照图9，第二部分38至少局部的外侧面的截面为齿轮状或者花边状，第二部分38上的齿轮状或者花边状的外侧面的至少局部与管状体6相嵌固定，从而使得第二部分38与管状体6相嵌的重合区域可以允许空气通过(即从第二气孔342通过)，且空气通过时，至少会被第二部分38的外侧面加热，从而形成热空气。当然不排除，管状体6的至少局部内侧面的截面为齿轮状或者花边状，第二部分38与管状体6上的齿轮状或者花边状内侧面的至少局部相嵌固定，从而界定出第二气孔342。
在一实施例中，可以参照图9和图10，沿热空气流动的方向，第二部分38位于第一部分37的下游，从而，加热器3与管状体6相嵌固定时，第一部分37凸显在管状体6之外。
在一实施例中，可以参照图9，第二部分38的横截面积大于第一部分37的横截面积，从而使得第二部分38和第一部分37之间形成有台阶面，该台阶面上设置有第三气孔39，空气可通过第三气孔39，进而进入气溶胶生成制品1中，其中，第三气孔39仅贯通第二部分38。可以通过削减、铸造等各种可用的工艺手段使第一部分37的横截面积小于第二部分38的横截面积，例如，通过削减的手段，将第一部分37上被第三气孔39贯通的部分削去。从而使得加热器3的总体质量减轻，根据热量公式：Q＝CMΔT(Q代表热容为C、质量为M的物体在温度变化量为ΔT时，所吸收或者释放的热量)，在物体的C值不变和ΔT相同的情况下，质量M越小，其所吸收或者释放的热量越少，所以，通过降低加热器3的质量，可以降低加热器3在升温过程中的能量消耗，起到降低能耗 的作用。
在一实施例中，如图11所示，加热器3同时具有第一气孔33、第二气孔342和第三气孔39。在一实施例中，加热器3只同时具有第一气孔33和第二气孔342，即第二部分38与第一部分37之间的台阶面不连贯(如图7所示)，从而使得第二部分38的外侧面至少局部轮廓为齿轮，且齿轮上未开设第三气孔39；或者第二部分38与第一部分37之间的台阶面高度过低(如图3至图5所示)，不足以开设第三气孔39，从而使得第二部分38的外侧面至少局部轮廓为波幅较小的花边形。
在一实施例中，第三气孔39均匀地分布在台阶面上，包括多个第三气孔39具有相同的孔径，任意相邻两第三气孔39之间具有相同的距离等。但是不以此为限，即第三气孔39可以不均匀地分布。
在一优选的实施中，加热体3和管状体6二者至少之一中含有等级430的不锈钢(SS430)，或含有等级420的不锈钢(SS420)，或含有铁镍的合金材料(比如坡莫合金)，或含有石墨合金等可在变化的磁场中发热的磁感性材料，从而管状体6二者至少之一在变化的磁场中因为产生涡电流和磁滞等而自发热，并加热流经的空气，进而利用空气加热气溶胶生成制品1。相应的，气溶胶产生装置还包括磁场发生器5，例如感应线圈，用于在交变电流下产生变化的磁场，且控制器42连接电芯41和感应线圈，并且可将电芯41输出的直流电流转化为交变电流，优选该交变电流的频率介于80KHz～400KHz；更具体地，所述频率可以在大约200KHz到300KHz的范围。
在一优选的实施中，管状体6由铁铬铝合金、镍铬合金、镍铁合金、铂、钨、银、导电陶瓷等电阻性导电材料制成，或者包含上述至少其一的导电材料，从而在导电时可以通过电阻的电热效应发热，来加热气溶胶生成制品1，使气溶胶生成制品1中的至少一种成分挥发，形成气溶胶。
在一可选的实施中，管状体6不可以发热，其主要用于保温，以降低加热器3外围的热量散失速度，或者降低气溶胶生成制品1内部温度流失的速度，从而能够实现降低加热器3的能耗。
具体的，管状体6可以仅仅位于第二部分38的外围，从而只对第二部分38 进行保温；或者
管状体6形成有接纳腔61，接纳腔61的一部分区域用于容纳气溶胶生成制品1，其余区域可以用来容纳第二部分38的至少局部，从而管状体6既能对至少对加热器3的第二部分38进行保温、降低加热器3的能耗，又能对气溶胶生成制品1进行保温，防止气溶胶在气溶胶生成制品1中冷凝，或者防止气溶胶生成制品1不能被充分烘烤导致浪费，同时，管状体6还能将加热器3保持在气溶胶产生装置中。可选的，管状体6由保温、隔热材料制成，如陶瓷等。可选的，管状体6的壁中具有真空隔热层。
管状体6可以发热，可以为电磁加热件、电阻加热件、红外加热件等，在一实施例中，管状体6通过发热来维持第二容纳腔61内部的高温环境，以防止气溶胶生成制品1内的热空气温度降低而不能充分烘烤气溶胶生成制品1，同时可以避免气溶胶在气溶胶生成制品1中发生冷凝；在另一实施例中，管状体6用于在用户刚抽吸气溶胶生成制品1时，高功率工作，以快速加热气溶胶生成制品1，使得气溶胶生成制品1能够迅速地产生气溶胶，以满足用户快速出烟/出雾的需求，从而提高用户体验。在进一步的实施例中，在满足用户第一口抽吸快速出烟/出雾的需求后，管状体6可以进入低功率的工作状态中，以配合其他加热器如空气加热器，维持气溶胶生成制品1内部的高温环境，防止空气在气溶胶生成制品1内部过度降温。在又一实施例中，加热组件3仅包括管状体6，通过管状体6来加热其内部的气溶胶生成制品1，使之产生气溶胶。在其他实施例中，管状体6可以为保温管，主要用于对气溶胶生成制品1进行保温，防止气溶胶生成制品1中的气流温度过快降低。
当加热器3和管状体6均含有等级430的不锈钢(SS430)，或含有等级420的不锈钢(SS420)，或含有铁镍的合金材料(比如坡莫合金)，或含有石墨合金等可在变化的磁场中发热的磁感性材料，磁感性材料可在变化的磁场中产生涡流和磁滞，进而发热。从而加热器3和管状体6均可在变化的磁场中发热，由于第二部分38的至少局部位于管状体6中，或者固定部的至少局部位于管状体6中，从而固定部的至少局部可能被管状体6磁屏蔽而不能产生涡流(此时，产生变化的磁场的磁感发生器位于加热组件的外围，可以理解的是，若产生变化的磁场的磁感发生器位于加热组件的内侧，则管状体6的局部可能被加热器3 磁屏蔽)，此时，第二部分38的温度和第二部分38内侧的基体31的温度可以通过热传导升温，热传导的热量来源为重合区的管状体6和显露在管状体6外的基体31。所以局部的磁屏蔽不会影响对流经固定部的空气的加热效果。
在一实施例中，沿热空气流动的方向，第二部分38位于第一部分37的上游，从而，加热器3与管状体6相嵌固定时，在管状体6足够长的情况下，第一部分37位于在管状体6的内部，若管状体6具有较短的轴向长度，则第一部分37的至少局部可以暴露在管状体6之外。
在一可选的实施中，加热器3一体成型，从而单位面积或者单位体积的第一部分37与第二部分38具有大致相同的加热效率；在其他实施例中，第一部分37与第二部分38为由不同种材料分体成型后在制成的一体结构，从而单位面积或者单位体积的第一部分37与第二部分38具有不尽相同的加热效率。
在一些可选的实施例中，第一部分37和第二部分38的轮廓均为圆形，在其他可选的实施例中，第一部分37的轮廓可以为方形、椭圆形、三角形等规则图形或者不规则图形，第二部分38的轮廓也可以为各种规则图形或者不规则图形中的一种，其可以与第一部分37的轮廓一致，也可以不一致。
在一实施例中，加热器3通过固定部32与管状体6相嵌连接，固定部32的至少局部位于管状体6的接纳腔61中，即固定部32的至少局部位于加热器3与管状体6重合区中。
在一实施例中，可参照图9，第二部分38通过固定部32与管状体6相嵌固定，从而第一部分37凸显在管状体6之外，且固定部32的至少局部嵌入管状体6中，从而固定部32与管状体6之间具有重叠区。其中，固定部32可以设置在第二部分38，或者固定部32连接第二部分38与第一部分37。
请参照图3至图5，凹槽341与管状体6的内壁共同界定第二气孔342。从而，空气通过第二气孔342时，同时与固定部32和管状体6接触而同时被双方加热。当固定部32具有多个，相邻两固定部32之间具有一第二气孔342时，可参照图7，并且空气通过第二气孔342时，空气同时与固定部32、基体31和管状体6接触而同时被三方加热。
在其他实施例中，固定部32设置在基体31的第一部分37上，从而整个加 热器3均位于管状体6的接纳腔61内，或者仅局部固定部32和该固定部32内侧的基体31显露在管状体6之外。
在其他实施例中，固定部32连接第一部分37和第二部分38，加热器3的局部显露在管状体6之外，局部位于管状体6的内部。
上述的加热组件及气溶胶产生装置，加热器3用于加热进入管状体6内部接纳腔61的空气，管状体6用于维持接纳腔61的高温环境，从而防止空气在接纳腔61内的气溶胶生成制品中流动时，温度过度下降，有助于提高空气烘烤气溶胶生成制品的充分度，和防止气溶胶在气溶胶生成制品冷凝。
上述的加热组件及气溶胶产生装置，通过削减、铸造等各种工艺手段使加热器3的局部截面积减小，即使得第一部分37的横截面积小于第二部分38的横截面积，从而能够有效地降低加热器3的总体质量，进而降低加热器3升至预设温度消耗的能量，有助于提高加热器3的热质量。加热器3的局部与管状体6相嵌固定，一方面加热器3可以通过管状体6保持在气溶胶产生装置中，另一方面，可以减小加热器3与管状体6的接触面积，增大管状体6与加热器3之间的热阻，可以进一步地阻碍热量散失，减小能耗。
在一实施例中，可以参照图13，加热组件还包括辅助加热件7，沿热空气流动的方向，辅助加热件7位于加热器3的下游，辅助加热件7与加热器3均与管状体6相嵌固定，其中辅助加热件7为电磁加热体、电阻加热体、红外加热体或者保温管等。辅助加热件7可以延长接纳腔的轴向长度，从而可以适配更长的烟支。
在一实施例中，还提供一种加热模组，可以参照图14，加热模组包括加热组件和保温壳8，加热组件可以包括单个加热器3，可替代地，加热组件可包括多于一个加热器3，该单个加热器3或该多个加热器3可被适当地布置以便最有效地加热气溶胶生成制品1，其中，多个加热器3可以构成对气溶胶产生制品1分段加热，多个加热器3中至少有两个加热器3可以具有不同的加热方式或加热效率。
请继续参阅图14，保温壳8内部形成有第一容纳腔81，气溶胶生成制品1 的至少局部可容纳于第一容纳腔81中；保温壳8的近端开设有与第一容纳腔81连通的第一插入口，气溶胶生成制品1的至少局部进入第一容纳腔81时，需穿过第一插入口；保温壳8的远端密封。
加热组件布置在第一容纳腔81中，其在第一容纳腔81中发热，以加热气溶胶生成制品1，进而生成气溶胶。保温壳8具有保温和隔热功能，其侧壁位于加热组件的侧向外围，其远端(底部)位于加热组件的下方，且密封，从而能够为加热组件提供更加完善的保温，有助于进一步降低加热模组的能耗。
在一实施例中，可参照图14，保温壳8的远端为外凸的拱形底部82，相对与平面底部，拱形底部82能够容纳更厚的空气层，从而可以通过更厚的空气来更加有效地阻碍热量向保温壳8传递，延长保温时间。
优选，拱形底部82经配置可以反射红外线。在一实施例中，拱形底部82内侧具有红外反射层，红外反射层为光亮材料，如铝箔、镍箔等，或者为金属镀膜，如镀金膜、镀银膜等。通过拱形底部82反射红外线，来阻隔热量向外传递，使热量保持在第一容纳腔81中，从而增强对加热组件的保温效果。而且相对平面底部，拱形底部82具有更大的洪红外线反射面积，从而保温效果更好。
进一步的，加热模组的至少局部暴露在拱形底部82的反射范围中；或者，气溶胶生成制品1容纳在第一容纳腔81后，其至少局部暴露在拱形底部82的反射范围中。从而拱形底部82反射的红外线能够射到加热组件上，或者射到气溶胶生成制品1上，使得被反射的红外线能够使加热组件或者气溶胶生成制品1升温，从而进一步地实现节能。其中，优选将拱形底部82的弧度设置为其反射的红外线汇合在加热组件上或者汇合在气溶胶生成制品1上，通过将保温壳8的远端设置为外凸的拱形，能够使其发射的红外线更加集中。优选，保温壳8为一体结构，从而其侧壁与底部之间无缝连接，使得拱形底部82能够更好的密封保温壳8的远端，同时能够减小保温壳8内部的漫反射，提高反射光线的集合度，并且还能防止热量在接缝处集中，导致局部温度过高。
在一些实施例中，保温壳8侧壁的内侧或者外侧也可以设置红外反射层，从而增加保温壳8侧壁的保温效果。
在一实施例中，可参照图14，保温壳8有绝热材料制成，更进一步的，保 温壳8的壁中具有真空夹层，包括拱形底部82的壁中具有真空夹层，和/或保温壳8的侧壁中具有真空夹层，通过真空夹层提高保温隔热效果。
在又一实施例中，加热组件仅包括管状体6，通过管状体6来加热其内部的气溶胶生成制品1，使之产生气溶胶。在其他实施例中，管状体6可以为保温管，主要用于对气溶胶生成制品1进行保温，防止气溶胶生成制品1中的气流温度过快降低。
第一容纳腔81内具有气流通道，抽吸气溶胶生成制品1时，第一容纳腔81内的空气沿气流通道从管状体6的远端进入管状体6的接纳腔61中。
第一容纳腔81内的气流通道包括第一气流通道和第二气流通道。第一容纳腔81中的部分空气通过第一气流通道流向第一气孔33，并通过所述第一气孔33进入接纳腔61中，其中，保温壳8的远端界定有凸形空气腔83，凸形空气腔83构成所述第一气流通道的一部分，凸形空气腔83可以位于第一气孔33的正下方；第二气流通道的至少局部环绕管状体6的外侧面设置，第一容纳腔81内的部分空气沿第一气流通道贴着管状体6的外侧壁从管状体6的近端流向第二气孔342的远端，并通过第二气孔342进入接纳腔61中，管状体6发热时，其侧壁可以加热第二气流通道中的空气，第二气流通道中的空气能够充分地利用管状体6的余热。即第一气流通道的至少部分空气从保温壳8的近端流向其远端，再通过凸形空气腔83，并经过加热体3，最终进入管状体6内的接纳腔61中。
进一步的，第二气流通道紧贴着管状体6的外侧面设置，以充分地利用管状体6的余热。
在一实施例中，第一气孔33与第二气孔342的远端连通，从第一气流通道流出的空气主要通过第一气孔33进入接纳腔61中，但也有部分空气通过第二气孔342进入接纳腔61中，同理，从第二气流通道流出的空气主要通过第二气孔342进入接纳腔61中，但也有部分空气通过第一气孔33进入接纳腔61中。
请参照图14，加热模组还包括支架36，支架36的至少局部布置在第一容纳腔81中，且支架36与所述保温壳8连接，加热组件连接支架9，并被支架9保持在第一容纳腔81中，支架9的侧壁与保温壳8的侧壁界定第一气流通道的 一部分，支架9的侧壁与管状体6界定第二气流通道的至少部分，从而第一气流通道和第二气流通道的至少局部通过支架9的侧壁分隔。
在一实施例中，可以参照图14，支架9的近端形成有第二插入口91，第二插入口91的至少局部位于第一插入口中，或者第二插入口91与第一插入口连通，气溶胶生成制品1需通过第二插入口91进入第一容纳腔81中。
支架9还包括肩部92和支架本体，肩部92环绕第二插入口91设置，且连接支架支架本体与保温壳8，使得第一容纳腔81的至少局部由保温壳8与肩部92界定，肩部92可以与保温壳8为一体结构；或者肩部92可以与支架本体一体注塑成型；或者肩部92可以与支架本体分体注塑成型，然后相互组装成一体结构。
其中，肩部92上开设有第一过气孔921，空气通过第一过气孔371进入第一容纳腔81，即加热模组的近端设置有第一过气孔921。具体的，第一过气孔921可以对应第一气流通道设置，并与第一气流通道连通，支架9的侧壁上开设有第二过气孔93，第二过气孔93连通第一气流通道和第二气流通道；或者，第一过气孔921可以对应第二气流通道设置，并与第二气流通道连通，支架9的侧壁上开设有第二过气孔93，第二过气孔93连通第一气流通道和第二气流通道；从而，通过第一过气孔921进入第一容纳腔81中的空气可以进入第一气流通道和第二气流通道中。即第一气流通道中的部分空气通过第二过气孔93分流到第二气流通道中，并且第二过气孔93位于支架9的侧壁，因此分流至第二气流通道内的气体依然是沿着从管状体6的近端流向其远端。
进一步的，请参照图14，第二过气孔93对应管状体6的近端设置。
当加热组件包括在变化的磁场中可发热的磁感性材料时，加热模组还包括磁感发生器(磁场发生器5)，磁感发生器绕制在支架9的外侧，且通过支架9保持在第一容纳腔81中，请参照图14，磁感发生器位于支架9与保温壳8之间。
在一实施例中，加热模组还包括屏蔽层101，屏蔽层101设置在磁感发生器的外围，屏蔽层101位于第一容纳腔81中，且处于保温壳8与磁感发生器(磁场发生器5)之间。屏蔽层101为磁屏蔽层，用于防止磁感发生器产生的磁场外漏，使得磁场更能集中在磁感性材料上，提高磁场的利用率和提高磁感性材料 的发热效率。
可以参照图15，亦可以有第二温度检测器102检测管状体6的温度，第二温度检测器102可以连接管状体6的侧壁外表面，并且连接控制器42。控制器42根据获取的第二温度检测器102检测的温度数据，对管状体6进行温控。在图15所示的实施例中，管状体6与加热器3未重合。
加热模组还包括与磁感发生器或者加热组件或者温度检测器电连接的引线，引线通过穿过第一气流通道或者第二气流通道，然后通过第一过气孔921引出。即，第一气孔33既能允许空气进入第一容纳腔81中，又能允许第一容纳腔81中的引线穿出，进而与控制器41电连接。
可选的，加热器3与管状体6由不同的磁感性材料制作，从而在相同的变化的磁场下具有不同的发热效率。
可选的，管状体沿6第一容纳腔81的轴向是断续设置的，即管状体6可以包括沿轴向分布的多个磁感受环，相邻两磁感受环相互之间不连接，不同的磁感受环可以对应不同的磁感发生器，从而控制器42通过控制不同的磁感发生器的工作顺序或者工作功率等使管状体6对气溶胶生成制品1分段加热。当然，各磁感受环可以置于相同的变化的磁场中，各磁感受环可以由相同的材料制成，或者由不同的材料制成。
上述的加热模组及气溶胶产生装置，保温壳8的近端具有第一插入口、远端密封的结构，加热组件设置在保温壳8中，从而加热组件在保温壳8之内发热，热量被保温壳8局限在其内部，从而能够对加热组件进行更加有效的保温，有助于降低加热模组的功耗。
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。
