 本发明的实施方式
下面将结合本申请各实施方式中的附图，对本申请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申请一部分实施方式，而不是全部的实施方式。基于本申请中的实施方式，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，都属于本申请保护的范围。
在本申请的描述中，需要理解的是，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个所述特征。
请参阅图1、图2，图1为本申请一实施例中的发热组件的组装示意图，图2为本申请一实施例中的发热组件的拆解示意图。结合图1、图2所示，该发热组件10包括发热体101、热电偶102以及陶瓷外壳103。发热体101上设置有容置结构1011a，该容置结构1011a为设置在发热体101上的一过孔1011b。热电偶102包括第一热电偶线1021、第二热电偶线1022以及导电电极1023。第一热电偶线1021的一端a以及第二热电偶线1022的一端b连接至导电电极1023，形成热电偶102的检测端112，该检测端112设置在容置结构内。陶瓷外壳103套设在发热体101的外表面。
本申请实施例通过在发热体101上设置容置结构1011a，将热电偶102的检测端1023设置在容置结构1011a内，由于热电偶102受磁场变化较小，从而可以通过设置在容置结构1011a内的热电偶102的检测端112精确检测到发热体101的温度。
其中，发热体101能在高速变化的磁场内产生涡流并发热。也即，发热体101在交变磁场的作用下发热。发热体101的材料可以是弹簧钢、铁素体不锈钢、碳钢、硅钢、铁铝、铁钴等合金。另外，发热体的形状可以是柱状、长方体、针状、十字状、片状等。
比如，本申请实施例的发热体101的材料为弹簧钢，本申请实施例的发热体101的形状为柱状。弹簧钢具有优良的综合性能，如力学性能（特别是弹性极限、强度极限、屈强比）、抗弹减性能（即抗弹性减退性能，又称抗松弛性能）、疲劳性能、淬透性、物理化学性能（耐热、耐低温、抗氧化、耐腐蚀等）。为了满足上述性能要求，弹簧钢具有优良的冶金质量（高的纯洁度和均匀性）、良好的表面质量（严格控制表面缺陷和脱碳）、精确的外形和尺寸。
其中，热电偶102是温度测量仪表中的测温元件，它直接测量温度，并把温度信号转换成热电动势信号，通过电气仪表转换成被测介质的温度。热电偶的应用极为广泛，它具有结构简单、制造方便、测量范围广、精度高、惯性小和输出信号便于远传等许多优点。另外，由于热电偶是一种有源传感器，测量时不需外加电源，使用十分方便。
其中，陶瓷外壳103的材料可以包括氧化锆。需要说明的是，氧化锆的热比容较大，其导热系数较小，这两点对于温度变化有平滑作用，从而保证发热组件10整体温度稳定，进而可以保证烟支口感。比如，外加氧化锆陶瓷外壳，其比热容较金属及氧化铝大，其导热系数也较金属和氧化铝小，这两点对于温度变化有平滑作用，从而保证被加热的烟丝温度稳定，保证了烟支口感。
进一步的，本申请实施例通过在发热体101上设置容置结构1011a，将热电偶102的检测端112设置在容置结构1011a内，由于热电偶102受磁场变化较小，且可以将容置结构1011a设置在发热体101的中部，从而可以通过设置在容置结构1011a内的热电偶102的检测端112精确检测到发热体101的温度。需要说明的是，这里所说的中部具体指的是发热体101上能较准确反映发热体101的实际温度的位置。
具体的，请继续参阅图3、图4，图3为本申请一实施例中的发热体的剖视图，图4为本申请一实施例中的发热组件的剖视图。结合图3、图4所示，该容置结构1011a为设置在发热体101的中部的一过孔1011b，过孔1011b贯穿发热体101，检测端112设置在过孔1011b内。一方面，本申请实施例可以不额外增加空间放置热电偶102；另一方面，该过孔1011b设置在发热体101的中部，使得设置在过孔1011b内的热电偶102的检测端112能较为准确的检测到发热体101的实际温度。
该过孔1011b具有相对设置的第一开口1111和第二开口1211，第一热电偶线1021的另一端从第一开口1111穿出，第二热电偶线1022的另一端从第二开口1211穿出。也即，第一热电偶线1021的另一端和第二热电偶线1022的另一端分别从发热体101的相对的两侧绕出，可以避免第一热电偶线1021和第二热电偶线1022短接对热电偶102造成影响。
相对应的，发热体101上还设置有第一线槽1012和第二线槽1013，第一线槽1012设置在第一开口1111的一侧，第二线槽1013设置在第二开口1211的一侧，第一线槽1012以及第二线槽1013均自发热体101的中部延伸至发热体101的底部。第一热电偶线1021从第一开口1111穿出并沿着第一线槽1012延伸，第二热电偶线1022从第二开口1211穿出并沿着第二线槽1013延伸。本申请实施例通过在发热体101上设置第一线槽1012和第二线槽1013，并将第一热电偶线1021设置在第一线槽1012内，第二热电偶线1022设置在第二线槽1013内，从而可以使得发热组件10不会因为第一热电偶线1021和第二热电偶线1022形成缝隙，造成热量损失。
其中，陶瓷外壳103的内轮廓与发热体101的外轮廓相匹配。发热体101的外表面与陶瓷外壳103贴合设置。也即，在本申请实施例中，发热体101、热电偶102以及陶瓷外壳103三者之间的组合方式使得发热组件10之间基本不存在缝隙，进而不会对热量造成损失。
此外，请继续参阅图1，图2，为了提高密封性，避免热量流失，可在发热体101、热电偶102以及陶瓷外壳103组装完成后，在陶瓷外壳103的底部采用陶瓷胶密封。
需要说明的是，本申请实施例的发热组件10应用于电子烟中。电子烟采用本申请实施例的发热组件10插入被加热烟支的烟丝部进行加热，其中发热组件10有一定物理形状和体积，在发热组件10插入烟支的烟丝部后，发热组件10中的发热体101散发的热量通过陶瓷外壳103均匀散发出去，对烟支的烟丝部进行加热，并且热电偶102可以准确获取发热体101的温度，从而可以及时调整发热体101的发热功率，进而保证烟丝的烟丝部均匀受热，进而提高产品的体验度。
请参阅图5，图6，图5为本申请另一实施例中的发热组件的组装示意图，图6为本申请另一实施例中的发热组件的拆解是一体。其中，图5、图6所示的发热体201与图1、图2、图3以及图4所示的发热体101的区别在于：图5所示的发热体201上的容置结构2011a为设置在发热体201的外表面的一第一凹陷部2011b。
需要说明的是，本申请另一实施例中的发热体201可以替换以上实施例的发热组件10中的发热体101。也即，采用本申请实施例的发热体201的发热组件20与以上实施例的发热组件101的区别仅仅在于采用的发热体的结构有差异，其余部件大致相同。
结合图5、图6所示，该发热组件20包括发热体201、热电偶202以及陶瓷外壳203。发热体201上设置有容置结构2011a，该容置结构2011a为设置在发热体201的外表面的一第一凹陷部2011b。热电偶202包括第一热电偶线2021、第二热电偶线2022以及导电电极2023。第一热电偶线2021的一端a以及第二热电偶线2022的一端b连接至导电电极2023，形成热电偶202的检测端212，该检测端212设置在容置结构2011a内。陶瓷外壳203套设在发热体201的外表面。
本申请实施例通过在发热体201上设置容置结构2011a，将热电偶202的检测端212设置在容置结构2011a内，由于热电偶202受磁场变化较小，从而可以通过设置在容置结构2011a内的热电偶202的检测端212精确检测到发热体201的温度。
其中，发热体201能在高速变化的磁场内产生涡流并发热。也即，发热体201在交变磁场的作用下发热。发热体201的材料可以是弹簧钢，可以是铁素体不锈钢，可以是碳钢，可以是硅钢，可以是铁铝、铁钴等合金。另外，发热体的形状可以是柱状，可以是长方体、可以是针状，可以是十字状，可以是片状等。
比如，本申请实施例的发热体201的材料为弹簧钢，本申请实施例的发热体201的形状为柱状。弹簧钢具有优良的综合性能，如力学性能（特别是弹性极限、强度极限、屈强比）、抗弹减性能（即抗弹性减退性能，又称抗松弛性能）、疲劳性能、淬透性、物理化学性能（耐热、耐低温、抗氧化、耐腐蚀等）。为了满足上述性能要求，弹簧钢具有优良的冶金质量（高的纯洁度和均匀性）、良好的表面质量（严格控制表面缺陷和脱碳）、精确的外形和尺寸。

其中，陶瓷外壳203的材料可以包括氧化锆。需要说明的是，氧化锆的比热容较大，其导热系数较小，这两点对于温度变化有平滑作用，从而保证发热组件20整体温度稳定，进而可以保证烟支口感。比如，外加氧化锆陶瓷外壳，其热比容较金属及氧化铝大，其导热系数也较金属和氧化铝小，这两点对于温度变化有平滑作用，从而保证被加热的烟丝温度稳定，保证了烟支口感。
进一步的，本申请实施例通过在发热体201上设置容置结构2011a，将热电偶202的检测端212设置在容置结构2011a内，由于热电偶202受磁场变化较小，且可以将容置结构2011a设置在发热体201的中部，从而可以通过设置在容置结构2011a内的热电偶202的检测端212精确检测到发热体201的温度。需要说明的是，这里所说的中部具体指的是发热体201上能较准确反映发热体201的实际温度的位置。
具体的，该容置结构2011a为设置在发热体201的外表面的一第一凹陷部2011b，第一凹陷部2011b设置在发热体201的中部。该发热体201上还设置有第二凹陷部2012和第三凹陷部2013，第一凹陷部2011b、第二凹陷部2012以及第三凹陷部2013相互连通，第二凹陷部2012以及第三凹陷部2013均自发热体201的中部延伸至发热体201的底部；第一热电偶线1021沿着第二凹陷部2012延伸，第二热电偶线1022沿着第三凹陷部2013延伸。
其中，陶瓷外壳203的内轮廓与发热体201的外轮廓相匹配。发热体201的外表面与陶瓷外壳203贴合设置。也即，在本申请实施例中，发热体201、热电偶202以及陶瓷外壳203三者之间的组合方式使得发热组件20之间基本不存在缝隙，进而不会对热量造成损失。
此外，请继续参阅图5，图6，为了提高密封性，避免热量流失，可在发热体201、热电偶202以及陶瓷外壳203组装完成后，在陶瓷外壳203的底部采用陶瓷胶密封。
