上述的发热机构10的制备方法，首先将第一导电引脚120和第二导电引脚130定位于第一模具内，使第一导电引脚120与第二导电引脚130相对定位；然后将第一浆料注入所述第一模具内，且成型出分别连接于所述第一导电引脚120和所述第二导电引脚130的导电发热基体110；然后将第二浆料注入第二模具内，以成型出具有容纳槽310的导热套300；然后将所述导电发热基体110置于所述容纳槽310内，使导热套300套设于导电发热基体110的外围并与导电发热基体110连接；最后将第三浆料注入所述安装间隙112内，以成型出包覆于所述第一导电引脚120的绝缘部200，使第一导电引脚120位于安装间隙112的部位与导电发热基体110绝缘，确保第一导电引脚120从导电发热基体110的第一端穿设于第二端，且第一导电引脚120仅与导电发热基体110的第二端连接，而第二导电引脚130与导电发热基体110的第一端连接。由于第一导电引脚120穿设于安装间隙112，且绝缘部200填充于安装间隙112，使第一导电引脚120在安装间隙112内与导电发热基 体110绝缘，又由于第一导电引脚120与导电发热基体110的一端连接，第二导电引脚130与导电发热基体110的另一端连接，使第一导电引脚120和第二导电引脚130分别与导电发热基体110的两端电连接，电流在导电发热基体110的两端流动，进而使导电发热基体110的整体部位均导电发热，使导电发热基体110具有较好的发热效果。由于导电发热基体110完全位于容纳槽310内并与导热套300连接，避免导电发热基体110直接裸露于外界，使导电发热基体110产生的热量传导至导热套300表面，使导热套300的热量直接作用于烟支上，以使导热套300加热烟支，使烟支散发出烟雾，提高了电子烟的加热效果。本发明的导电发热基体110完全位于所述容纳槽310内并与所述导热套300连接，即导热套300包覆导电发热基体110，且导电发热基体110通过第一导电引脚120和第二导电引脚130导电发热，避免了传统的通过印刷工艺成型的导电片进行加热的方式，不存在发热机构10的发热性能较差甚至失灵的问题，提高了电子烟的使用可靠性，在使用过程中也不存在重金属等有毒有害物质污染。
进一步地，将第三浆料注入所述安装间隙112内，以成型出包覆于所述第一导电引脚120的绝缘部200的步骤具体为：通过灌胶工艺将第三浆料注入所述安装间隙112内，以成型出包覆于所述第一导电引脚120的绝缘部200，使第三浆料能够快速注入安装间隙112内。
进一步地，将第一浆料注入所述第一模具内，且成型出分别连接于所述第一导电引脚120和所述第二导电引脚130的导电发热基体110的步骤具体为：通过灌胶工艺将第一浆料注入所述第一模具内，且成型出分别连接于所述第一导电引脚120和所述第二导电引脚130的导电发热基体110，使第一浆料快速注入第一模具内，同时使导电发热基体110较好地连接于第一导电引脚120和第二导电引脚130。
进一步地，将第二浆料注入第二模具内，以成型出具有容纳槽310的导热套300的步骤具体为：通过灌胶工艺将第二浆料注入第二模具内，以成型出具有容纳槽310的导热套300，使第二浆料快速注入第二模具内。可以理解，在其他实施例中，第一模具和第二模具可以为同一模具，将第一浆料和第二浆料分别先后注入同一模具的不同位置处，以在同一模具中先后成型出导电发热基体110和导热套300。
进一步地，在将第三浆料注入所述安装间隙112内，以成型出包覆于所述第一导电引 脚120的绝缘部200的步骤之前，以及在将所述导电发热基体110置于所述容纳槽310内的步骤之后，制备方法还包括：将第四浆料注入导电发热基体110与容纳槽310内壁之间，以成型出导热连接部400。在本实施例中，导热连接部400分别与导电发热基体110和导热套300内壁连接。
进一步地，将第四浆料注入导电发热基体110与容纳槽310内壁之间，以成型出导热连接部400的步骤具体包括：首先将第四浆料灌注于导电发热基体110与容纳槽310内壁之间；然后烧结成型出导热连接部400，使导热连接部400成型于导电发热基体110与容纳槽310内壁之间。在本实施例中，导热连接部400的材质与导热套300的材质相同，均为陶瓷或其他导热材料，使导热连接部400与导热套300紧固连接。在其他实施例中，导热连接部400的材质还可以与导电发热基体110的材质相同，均为导电发热陶瓷材质，使导热连接部400与导电发热基体110的紧固连接。
为使导热连接部400较好地烧结成型于导电发热基体110与导热套300之间，进一步地，烧结成型出导热连接部400的步骤具体包括：首先以400℃～600℃持续烧结第一预定时间；然后以1000℃～1500℃持续烧结第二预定时间，第一预定时间大于第二预定时间，通过先慢烧结后快烧结方式使导热连接部400较好地烧结成型于导电发热基体110与导热套300之间。在本实施例中，第一预定时间为30min～1h，第二预定时间为15min～40min。
进一步地，在将第四浆料注入导电发热基体110与容纳槽310内壁之间，以成型出导热连接部400的步骤之前，以及在将所述导电发热基体110置于所述容纳槽310内的步骤之后，制备方法还包括：将导电发热基体110与导热套300相对定位，使导电发热基体110的轴心与导热套300之间的间隙较均匀，进而使导电发热基体110的轴心与导热套300的轴心重合，如此，使后续第四浆料能够均匀注入导电发热基体110与导热套300之间的间隙中。
然而，在第四浆料注入导电发热基体110与容纳槽310内壁之间，注入导电发热基体110与容纳槽310内壁之间的第四浆料内存在空气气泡，使导电连接部结构表面存在气孔，进而使导电连接部的成型质量较差，为提高导电连接部的成型质量，进一步地，在将第四浆料注入导电发热基体110与容纳槽310内壁之间，以成型出导热连接部400的步骤之前，以及在将所述导电发热基体110置于所述容纳槽310内的步骤之后，制备方法还包括：对 导电发热基体110与导热套300之间进行抽真空操作，以去除导电发热基体110与导热套300之间的空气，解决了导电连接部的成型质量较差的问题。
为提高导电连接部的成型质量，例如，在烧结成型出导热连接部400的步骤之前，以及在将第四浆料灌注于导电发热基体110与容纳槽310内壁之间的步骤之后，成型出导热连接部400的步骤还包括：同时对导电发热基体110和导热套300进行振荡操作，以消除注入于导电发热基体110与导热套300之间的第四浆料的气泡，进而提高了导电连接部的成型质量。进一步地，同时对导电发热基体110和导热套300进行振荡操作的步骤具体为：同时对导电发热基体110和导热套300以预设转速进行旋转振荡操作，以消除注入于导电发热基体110与导热套300之间的第四浆料的气泡。在本实施例中，预设转速为800r/min～1500r/min。在本实施例中，预设转速为1000r/min，使导电发热基体110与导热套300之间的第四浆料的气泡能够快速消除。
与现有技术相比，本发明至少具有以下优点：
1、第一导电引脚120可以外接于电源的正极，第二导电引脚130可以外接于电源的负极，由于第一导电引脚120穿设于安装间隙112，且绝缘部200填充于安装间隙112，使第一导电引脚120在安装间隙112内与导电发热基体110绝缘，又由于第一导电引脚120与导电发热基体110的一端连接，第二导电引脚130与导电发热基体110的另一端连接，使第一导电引脚120和第二导电引脚130分别与导电发热基体110的两端电连接，电流在导电发热基体110的两端流动，进而使导电发热基体110的整体部位均导电发热，使导电发热基体110具有较好的发热效果；
2、由于导电发热基体110完全位于容纳槽310内并与导热套300连接，避免导电发热基体110直接裸露于外界，使导电发热基体110产生的热量传导至导热套300表面，使导热套300的热量直接作用于烟支上，以使导热套300加热烟支，使烟支散发出烟雾，提高了电子烟的加热效果；
3、本发明的导电发热基体110完全位于所述容纳槽310内并与所述导热套300连接，即导热套300包覆导电发热基体110，且导电发热基体110通过第一导电引脚120和第二导电引脚130导电发热，避免了传统的通过印刷工艺成型的导电片进行加热的方式，不存在发热机构10的发热性能较差甚至失灵的问题，提高了电子烟的使用可靠性。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
