请参考图1和图2，图1为本申请一实施方式提供的加热模组100的立体分解图。图2为本申请一实施方式的加热模组100的部分剖视图。本申请提供的加热模组100可以用于发烟装置。所谓发烟装置是指一种吸烟辅助配件，用于供用户吸食烟制品。
加热模组100包括底座10、设置于底座10上的发热组件20以及设置于发热组件20远离底座10一端的烟杯30。发热组件20与烟杯30之间设置有一连接器40。底座10与发热组件20之间设置有支架50。加热模组100还包括一壳体60，壳体60固定于底座10上，并罩设发热组件20、烟杯30、连接器40以及支架50。发热组件20、烟杯30与壳体60之间形成有一腔体100a。腔体100a腔体100a中填充有隔热组件70。
承载支架50、发热组件20、连接器40、烟杯30和壳体60依次安装在底座10上。底座10上设置有支架50和壳体60的固定部。在本实施方式中，底座10上设置有用于固定支架50的多个插孔11以及用于固定壳体60的台阶状的固定部12。底座10可以采用塑料材质，塑胶材料具有低导热系数，耐高温的塑胶材料在满足使用要求的同时具有保温隔热的效果。此外，底座10上还设置有供空气进入加热模组100的进气孔。
发热组件20包括发热体21和导热体22。导热体22中开设有容置腔22a。发热体21收容于容置腔22a中。容置腔22a可以是开设于导热体22中的盲孔或者通孔。在一个实施方式中，导热体22和容置腔22a均为圆柱形，且导热体22与容置腔22a同轴设置，以使从发热体21传递至导热体22的热量均匀。此外，导热体22中还形成有多条气道23。气道23沿导热体22与底座10相对的一端延伸至导热体22与烟杯30相对的一端，用于将空气从底座10导向烟杯30。
发热体21可以采用电阻发热丝。电阻发热丝具有呈螺旋状的主体211和与主体211连接的两个通电端212。两个通电端212可以穿过底座10上的开孔与供电模组相连接。导热体22作为发热组件20里面完成热量交换、加热空气的核心部件，可以采用高导热系数的材料。导热体22体积小且与空气接触面积尽可能大，使得与空气的对流换热过程可以充分完成。导热体22的材料可选用：氧化铝、氧化锆、氮化硅等材料的烧结体；也可选择金属类材料，如：铝、铜、铁等金属材料。其中，当选用金属材料制备导热体22时，需要对导热体22表面需要进行绝缘处理，以防止导热体22与发热体21接触时使得发热体21出现短路问题。
烟杯30为蒸发介质的容器，用于承载或者固定蒸发介质。蒸发介质可以为，例如烟支1000或者烟丝等。发热组件20的一部分热量通过连接器40传输到烟杯30中，起到烘烤烟支1000、促进烟支1000尼古丁释放的作用。烟杯30的杯壁薄，体积小以降低烟杯的重量。在一个实施方式中，烟杯30的杯壁的厚度为0.1毫米至0.5毫米。在一个具体的实施例中，烟杯30的杯壁的厚度为0.15毫米至0.2毫米。在一个具体的实施例中，烟杯30的杯壁的厚度为0.2毫米。烟杯30的形状和尺寸可以与烟支对应，例如设置为圆柱状。烟杯30的内径，烟杯30的长度需要与烟支对应以使烟杯30环绕在烟支的烟草部外周。例如为了与菲莫国际的烟支对应，在一个实施方式中，烟杯长度为12.5厘米，直径7.35毫米。烟杯30的材料可选用：金属、例如不锈钢等，陶瓷等具有较高导热能力的材料。为了起到辅助加热的作用，在一些实施方式中，烟杯30的材料包括金属或者合金材料，例如，铝、铜、不锈钢等，或者包括陶瓷材料。
连接器40用于将烟杯30与发热组件20连接在一起。具体地，连接器40一端与发热组件20直接接触，另一端与烟杯30直接接触。请参考图3，连接器40包括安装台41和设置于安装台41朝向烟杯30一侧的限位部42。烟杯30安装于安装台41上。安装台41大致呈一空心圆环型。安装台41中间的开口，或者说挖孔的位置，用于供空气从发热组件20流向烟杯30。安装台41中开设有一收容腔41a，发热组件20的一端收容于收容腔41a中。
限位部42沿着安装台41的外周设置并延伸至烟杯30内部，用于限制烟支1000插入烟杯的深度，由此调节蒸发介质与发热组件20的距离，以控制蒸发介质的加热温度。限位部42用于限制蒸发介质插入烟杯30的深度。限位部42远离发热组件20一侧的表面与发热组件20靠近烟杯30一侧的表面之间的间距h大于1mm且小于5mm。当烟支1000与发热组件20的间距h小于1mm时，烟支1000容易因太靠近发热组件20而产生焦糊味；当烟支1000与发热组件20之间的间距h大于5mm时，通过发热组件20被加热的空气因温度衰减不足以雾化烟支1000。因此，烟支1000与发热组件20之间的距离应大于1mm且小于5mm。
本申请不限制限位部42的形状。在本实施方式中，限位部42包括沿安装台41外周间隔设置的多个限位柱421。限位柱421的形状可以为棱柱也可以为圆柱状。在其他实施方式中，限位部42也可以具有沿安装台41外周设置一整圈的挡墙形状。
限位部42可以同时用于固定烟杯30。限位部42固定烟杯30的方式。在本实施方式中，限位部42包括与烟杯30内壁平行的第一表面42a，第一表面42a与烟杯30内壁抵接，烟杯30的底壁与安装台41的上表面抵接。换句话说，限位部42的第一表面42a与安装台41的上表面共同形成一台阶状的固定部，烟杯30固定于该固定部上。具体地，在本实施方式中，多个限位柱421远离收容腔41a的外表面共同构成该第一表面42a。
在其他实施方式中，例如也可以在限位部42表面设置有凸块，烟杯30中开设有凹部，通过限位部42表面的凸块与烟杯30中的凹部相嵌合，将限位部42与烟杯30进行固定。
总而言之，在本实施方式中，连接器40拥有三个功能。第一、支撑烟杯30的作用，同时与支架50一起对发热组件20进行固定与定位；第二、将烟杯30与发热组件20连接到一起，起到将发热组件20的一部分热量传导到达烟杯30，烟杯30的温度提高有利于烟支1000雾化，释放尼古丁；第三、连接器30上的限位部42可以用来控制烟支1000插入的深度，控制烟支1000与发热组件20之间的距离，连接器40的热传导系数小于发热组件20和烟杯30，同时连接器40与烟杯30和发热组件20采用骨位接触，接触面积最少化，最大限度的降低发热组件20的热量向烟杯30的传导，使发热组件20的大部分热量用来加热空气，小部分传导到烟杯20保持烟杯20的温度。
请参考图4（a），在本申请的其他实施方式中，限位部42不用于固定烟杯30。限位部42与烟杯30内壁空开间隔设置。安装台41上还设置有固定部44，烟杯30通过固定部44固定于安装台41上。固定部44可以是如限位部一样，包括沿安装台41外周间隔设置的多个固定柱441。固定部44也可以是其他结构和位置，例如凹槽，用于与烟杯30的杯壁上设置的凸起卡合。在此不再一一列举。
连接器40上还设置有限位槽43，发热组件20的端部抵接于限位槽43中，用来限定发热组件20的位置。在本实施方式中，限位槽43可以开设于限位部42上。具体地，限位槽43可以开设于限位部42朝内一侧。限位槽43可以包括第一限位表面431和第二限位表面432。第一限位表面431和第二限位表面432大致垂直。第一限位表面431与导热体22的顶面平行并抵接，第二限位表面432与导热体22的周侧面平行并抵接。
请参考图4（b），在本申请的另一实施方式中，限位槽43也可以开设于安装台41上。第一限位表面431和第二限位表面432位于所述安装台41远离限位部41的一侧。
此外，连接器的材料可选用：氧化锆陶瓷、二氧化硅、陶瓷等耐高温低导热能力的材料。
支架50起到支撑发热组件20与烟杯30的作用。支架50还与连接器40共同固定发热组件20。支架50包括一支撑台51和间隔设置于支撑台51上靠近发热组件20一侧的多个定位柱52。支架50大致呈一空心圆环型。支架50中间的开口，或者说挖孔的位置，用于供空气从流向发热组件20以及供两个通电端212穿过以与供电模组相连接。多个定位柱52围绕支撑台51的外周设置。发热组件20固定设置于支撑台51上，发热组件20的底面的一部分与支撑台51抵接。发热组件20夹设于多个定位柱52之间。具体地，发热组件20的外周壁与定位柱52的内侧壁抵接。定位柱52仅夹设发热组件20的端部。
支架50还包括设置于支撑台51靠近底座10一侧的多个第一固定件53。底座10上设置有与第一固定件53配合的第二固定件11。第一固定件53与第二固定件11嵌合将支架50固定于底座10上。第一固定件53与第二固定件11可以为插销和插孔。在本实施方式中，第一固定件53包括多个插销。第二固定件11包括多个插孔11。底座10与支架50之间通过几个较小的点接触，使得接触面积较小，减小传导导热的热量损失。但本申请支架50和底座10的连接方式不限于此。
支架50的材料为氧化锆陶瓷、二氧化硅、陶瓷等耐高温的材料。其可以减少传导导热，降低热量损失。采用几个骨位以及较小的接触面固定住发热组件20进一步的降低传导导热的热量损失。
壳体60可以空心圆柱状。壳体60的周壁卡止在底座10的台阶状的固定部12上。壳体60的外壁上开设有通气孔62。该通气孔62位于壳体60接近底座10的一端。壳体60可以采用塑料材质，塑胶材料自身拥有低导热系数的特点，耐高温的塑胶材料在满足使用要求的同时具有保温隔热的效果。壳体60与烟杯30的接触面积小、与底座10的接触面积小，从而减小因传导导热的热量损失。
发热组件20的导热体22在工作时的温度可达400℃，因此，保温隔热措施就变得十分重要。在一个实施方式中，隔热组件70包括第一隔热组件71和第二隔热组件72。发热组件20与壳体60之间形成有第一隔热腔100a，第一隔热腔100a中设置有第一隔热组件71。烟杯30与壳体60之间形成有第二隔热腔100b。第二隔热腔100b中设置有第二隔热组件72。第一隔热组件71包括填充于第一隔热腔100a的隔热材料。第二隔热组件72包括填充于第二隔热腔100b的隔热材料。
隔热材料可以选自玻璃纤维、真空隔热管、气凝胶、隔热棉等。玻璃纤维拥有较好的耐热性、非常低的导热率、较好的阻燃性，且玻璃纤维是无毒无害、高温下无产生异味的材料。在一个实施方式中，选用玻璃纤维做保温隔热材料。将玻璃纤维包裹、填充在壳体60与烟杯30、壳体60与发热组件20之间，通过使玻璃纤维包裹住发热组件20最核心的工作部件导热体22上，一方面可以将发热组件20释放的热量包裹住，提高发热组件20的工作效率；另一方面，可以有效的组织热量以辐射的形式向壳体60扩散流失，可以有效的提高发热体的工作效率，有效的减小热量损失，降低外壳温升。
请参考图5，在其他实施方式中，第一隔热组件71包括第一隔热体711和第一热反射体712。第一热反射体712设置于第一隔热体711与壳体60之间。第二隔热组件72包括第二隔热体721和第二热反射体722。第二热反射体722设置于第二隔热体721与壳体60之间。在一些实施例中，第一隔热组件71和第二隔热组件72也可以为分体结构。其中，第一隔热体711和第二隔热体721可以为分体结构，且第一热反射体712和第二热反射体722也为分体结构，在此不再赘述。本实施例的加热模组在发热组件20和壳体60之间形成的第一隔热腔100a内设置第一隔热组件71，第一隔热组件71包括第一隔热体711和第一热反射体712，第一热反射体712位于第一隔热体711与壳体60之间。本实施例通过设置第一隔热体711来降低发热组件20的热量损失，以提高发热组件20的工作效率，并通过在第一隔热体711的外侧设置第一热反射体712，由于第一热反射体712能够将透过第一隔热体711的辐射热能再反射至第一隔热体711中，进而通过第一隔热体711和第一热反射体712的配合使用，能够大大降低发热组件20的热量损失。此外，上述设置降低了壳体60的温度，提升了发烟装置使用时的舒适感。
进一步的，本实施例通过在烟杯30和壳体60之间形成的第二隔热腔100b内设置第二隔热组件72，第二隔热组件72包括第二隔热体721和第二热反射体722，第二热反射体722位于第二隔热体721与壳体60之间，因而，通过第二隔热体721和第二热反射体722的配合使用，降低了烟杯30的热量损失，使得烟杯30内的烟制品能够充分地被进入烟杯30内的热空气所加热，从而有利于提高烟制品的雾化效率，以便吸食者能够及时地吸食烟制品。
在本实施例中，第一热反射体712为铝箔。具体的，第一热反射体712为铝箔卷材。铝箔卷材包覆在多孔隔热材料的外周侧。
具体的，铝箔具有良好的延展性，且自身热阻较小，对辐射热能的吸收率较低，此外，由于铝箔表面光滑，因而能够将80%~95%的热能反射至第一隔热体711上。故而，本实施例通过多孔隔热材料和铝箔的配合使用，能够大大降低导热体22中的热量损失，从而进一步提升导热体22的工作效率。此外，上述设置进一步降低了烟杯30中的热量损失，从而进一步提升了发烟装置使用感。
在本实施例中，由于导热体22的与支架50相接触，因此，为了防止导热体22中的热量传递至支撑台51上，第一隔热体711还设置于壳体60于支架50之间，从而可以进一步降低导热体22中的热量损失。
请参照图5，在一些实施例中，第一隔热体711为隔热罩。隔热罩套设在导热体22和烟杯30的外周侧。其中，隔热罩的材料可以包括玻璃纤维、气凝胶等。
第一热反射体712为热反射薄膜。热反射薄膜贴附在隔热罩的外周壁上。具体的，热反射薄膜可以为金、银、镍等金属薄膜，或者，还可以为镀有金属材料的聚酯、聚酰亚胺薄膜等能够将能够反射辐射热能的薄膜材料。
可以理解的是，由于薄膜材料的表面平整度高，尤其是金属薄膜，其膜层表面的光滑度较高，因而，相较于铝箔卷材，热反射薄膜对热能起到更好的反射作用。当透过隔热罩的少量辐射热能传输至热反射薄膜表面时，大部分热量能够被再次反射至隔热罩上，从而大大降低了热量向壳体60上传输的几率，能够对导热体22及烟杯30起到更佳的保温隔热作用。
具体的，可以采用电镀工艺或者溅射工艺在隔热罩的外周壁上形成一层热反射薄膜，进而在加热模组200的组装过程中，直接将贴附有热反射薄膜的隔热罩套设在烟杯30和导热体22的外周侧，以达到双重隔热效果，从而有效降低导热体22和烟杯30的热量损失。
进一步的，由于隔热罩对热能具有较佳的隔热效果，热反射薄膜对热能具有较佳的反射效果，进而在第一隔热腔100a及第二隔热腔100b内部空间一定的条件下，通过对隔热罩厚度及热反射薄膜厚度的调配，在减少辐射热能损失的同时，可以使导热体22及烟杯30的热量损失达到最小化。比如，可以将隔热罩的厚度设置为接近第一隔热腔100a及第二隔热腔100b内部空间所能容纳的厚度值，然后通过电镀或溅射工艺在隔热罩的外壁上形成一层极薄的热反射薄膜，从而通过对厚度的调配来实现热能损失的最小化。在另一些实施例中，热反射薄膜也可以形成于壳体60的内壁上，在此不再赘述。需要说明的是，在上述各实施例中，均以第二隔热组件72与第一隔热组件71一体成型为例进行说明，其中，第二隔热体721的结构及材料可以参照第一隔热体711的描述，第二热反射体722的结构及材料可以参照第一热反射体712的阐述，在此不再赘述。
请继续参阅图6，在一些实施例中，第一隔热腔100a位于壳体60与发热组件20之间以及底座10与发热组件20之间，换句话说，第一隔热组件71设置于壳体60与发热组件20之间以及底座10与发热组件20之间。
具体的，第一隔热腔100a包括第一子隔热腔n1和第二子隔热腔n2。第一子隔热腔n1位于壳体60与导热体22之间。第二子隔热腔n2位于支架50与导热体22之间。其中，第一子隔热腔n1与第二子隔热腔n2连通设置。
第一隔热组件71包括隔热材料和铝箔。隔热材料填充在第一子隔热腔n1以及第二子隔热腔n2内。隔热材料为多孔隔热材料。铝箔包覆于隔热材料位于第一子隔热腔n1内的部分。
上述设置可以同时降低导热体22的热量传递至壳体60及底座10上的几率，也即，减少了导热体22侧部及底部的热量损失，进而可以最大程度提高发热组件20的工作效率，以使发热组件20内部的空气能够被充分加热。另外，在另一些实施例中，第一隔热腔100a还可以仅位于底座10与发热组件20之间。第一隔热组件71设置于第一隔热腔100a内，换句话说，第一隔热组件71仅设置于底座10与发热组件20之间，在此不再赘述。
此外，发热组件20的温度控制由发烟装置的温度控制模块完成。温度控制模块可以实时监测发热组件20在工作过程中的实时温度，并可根据实时温度进行相应的调整，从而保证发热组件20在工作过程中烘烤蒸发介质的温度的一致性，保证蒸发介质的雾化效果和尼古丁的释放。温度的测量方式，可以使用阻值随温度变化而变化的电阻发热丝，采用电阻温度系数（temperature coefficient of resistance，TCR）的测量方式；也可使用通过感温元件采集温度的实时测量方式，采用感温元件进行温度测量时需要将感温元件紧贴的安装在需要检测的部件上。其中，TCR的测温方式所谓不需要额外增加感温元件，而是利用发热丝的平均温度电阻特性来监测温度。
在一个具体的实施方式中，本申请的加热模组100还包括温度检测模组80。温度检测模组80包括第一感温元件81和第二感温元件82。第一感温元件81安装在支架50和底座10上，紧贴着发热组件20的导热元件22，用于检测发热组件20的温度。第一感温元件81例如可以是热敏电阻类感温元件或者热电偶。第二感温元件82安装在底座10上，并设置于烟杯30的外侧，用于检测烟杯30的温度。
在进行加热模组100的装配时，首先，将隔热组件70安装于壳体60中；将第一感温元件81安装在支架50上，将支架50和第二感温元件82安装在底座10上；将发热体21放置于导热体21的容置腔22a内构成发热组件20，通过连接器40将发热组件20和烟杯30连接，将三者形成的整体安装于底座10和支架50上；将将整个组件放入安装有隔热组件70的壳体60中。
加热模组100的工作原理如下，空气通过壳体60外壁的通气孔62以及底座10下方的进气孔进入加热模组100内部，在抽吸过程中，发热体21通电发热，热量传导至导热体22，空气通过导热体22中设置的气道23与导热体22完成热量交换进入烟杯30中，被加热的空气烘烤蒸发介质释放尼古丁、使烟支1000雾化，雾化后的烟雾通过吸嘴被用户吸食。同时，通过连接器40将发热组件20的一部分热量传输到烟杯30中，起到烘烤烟支1000、促进烟支1000尼古丁释放的作用。
请参考图7，本申请还提供一种发烟装置1。发烟装置1包括上盖、底壳、电池、印刷电路板（PCB）板、支撑架、加热模组100六大部件。组装时将电池、PCB板安装在支撑架上，然后将支撑架安装放入底壳中，再将加热模组100安装在支撑架上，最后装配好上盖，整机组装完成。
请参考图8，发烟装置1包括电源模组200、驱动模组300、温度控制模组400、加热模组100。工作时，电源模组200供电，驱动模组300使发热体21，例如电阻发热丝开始工作，温度控制模组400控制电阻发热丝的温度。电阻发热丝释放的热量以热传导的方式传导到导热体22上，导热体22的热量以与空气进行对流换热的方式传导到气道23内的空气中，完成加热空气的工作，当使用者有抽吸动作时，被加热的空气进入到烟杯内部开始烘烤蒸发介质，使烟支1000雾化产生烟雾，释放处尼古丁供吸食者使用。
相较于现有技术，本申请的加热模组通过在烟杯内侧设置限位部，用来调节烟支与发热模组之间的间距，从而使烟支能够正常产生供用户抽吸的烟雾，提升抽吸口感。此外，通过将限位部设置为能够将烟杯固定在连接器上的柱状体，能够降低烟杯与连接器的接触面积，从而防止热量从发热组件过多地传导至烟杯而造成的热损失。
下面将结合本发明各实施方式中的附图，对本发明中的技术方案进行清楚、完整地描述。显然，所描述的实施方式仅仅是本发明一部分实施方式，而不是全部的实施方式。基于本发明中的实施方式，本领域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方式，都属于本发明保护的范围。
