具体实施方式
为了更清楚地说明本发明的技术方案，以下结合附图及实施例，对本发明的技术方案进行进一步详细说明，显而易见地，下面描述仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些实施例获得其他的实施例。
实施例一，一种电热丝组件，参照图 2 ，该电热丝组件包括发热部 2 和连接部 3 ，连接部 3 用于与电子烟的驱动电路（图中未示）电性连接以向发热部 2 输送电能，发热部 2 用于在通电后发热使得烟油雾化形成烟雾供用户吸食。连接部 3 包括由发热部 2 两端向外延伸形成的第一连接端 31 和第二连接端 32 ，第一连接端 31 和第二连接端 32 的外周面上均包裹有用于支撑电热丝组件的金属片 4 。参照图 3 ，第一连接端 31 和第二连接端 32 的远离发热部 2 的端面与对应金属片 4 的远离发热部 2 的端面位于同一平面内，第一连接端 31 和第二连接端 32 的远离发热部 2 的端面与金属片 4 的远离发热部 2 的端面平齐，此种结构使所述第一连接端 31 及第二连接端 32 与对应金属片 4 具有较长的连接区域，连接较为可靠，以使电热丝的整体阻值较为稳定，保证了雾化烟雾的稳定性，避免了仅用金属片 4 的端部连接时容易使金属片 4 与第一连接端 31 及第二连接端 32 脱落的问题；同时在生产过程中，将金属片 4 包覆在电热丝卷中定义的若干个所述第一连接端 31 和第二连接端 32 上，然后进行裁切电热丝，便快速获取电热丝单体，因而该种结构便于生产制造，提高了生产效率。金属片 4 的电阻率远低于第一连接端 31 和第二连接端 32 的电阻率，在电热丝组件通电工作的过程中，由于金属片 4 的存在，不仅可增强所述连接部 3 的结构强度，使生产电子烟时便于插设在相应的固定部件上，提高生产效率，而且使所述连接部 3 的横截面积较大，从而使第一连接端 31 和第二连接端 32 所处区域的发热量远小于发热部 2 的发热量，减少能耗，便于驱动电路驱动所述电热丝组件工作。
实施例二，参照图 3 电热丝组件的第一连接端 31 和第二连接端 32 的远离发热部 2 的端 从对应金属片 4 的远离所述发热部 2 的一端伸出 ，即第一连接端 31 和第二连接端 32 的远离发热部 2 的端面延伸至金属片 4 的外部。本发明实施例与上述实施例的结构相似，同理，也具有相应的技术效果。
实施例三，发热部 2 、第一连接端 31 和第二连接端 32 是一体成型的结构，并采用相同的材料制成，该材料为高电阻率的合金材料制成，例如镍铬合金、镍铬铁合金、铁铬合金或康铜合金等。例如可选用康铜 6J40 、 Cr20Ni80 等，满足电热丝组件快速发热的要求。
实施例四，发热部 2 、第一连接端 31 和第二连接端 32 均为细丝状结构，优选地，发热部 2 、第一连接端 31 和第二连接端 32 均采用同一电热丝线材制成。将电热丝线材卷绕形成螺旋状形成发热部 2 ，并且在发热部 2 两端延伸出合适长度的电热丝形成第一连接端 31 和第二连接端 32 。
实施例五，参照图 2 、图 5 ，发热部 2 、第一连接端 31 和第二连接端 32 的截面是圆形的合金材料，第一连接端 31 和第二连接端 32 分别由发热部 2 两端延伸，第一连接端 31 和第二连接端 32 的延伸距离相同或者一长一短不等距该不等距可以是第一连接端 31 长于第二连接端 32 ，或第二连接端 32 长于第一连接端 31 ，根据具体的接线要求设定并相对设置在呈螺旋状的发热部 2 两端，参照图 3 、图 6 和图 16 ，金属片 4 的展开形状为片状金属 6 ，金属片 4 包扎在第一连接端 31 以及第二连接端 32 的外周面上，使得金属片 4 呈多层管状层叠包裹固定在发热部 2 两端的第一连接端 31 和第二连接端 32 表面，牢靠地夹持固定在第一连接端 31 和第二连接端 32 上。
本发明中并不限定电热丝组件中构成发热部 2 和连接部 3 的电热丝 5 的形状，电热丝 5 可以使细丝状、片状、条状或者截面为圆形、椭圆形、多边形包括三角形，矩形等或其他几何形状。在制作过程中保证金属片 4 能够紧密包裹住连接部 3 即可。
金属片 4 由低电阻率的金属材料制成，该低电阻率的金属材料可以为金、银、铜、铁、锌、锡及其合金等的其中一种，或者铜镍合金、镧铝合金等低电阻率的合金，在本发明中规定电阻率低于 2.5 × 10-8 Ω m 的材料为低电阻率的材料。由于连接部 3 的第一连接端 31 和第二连接端 32 包裹有低电阻率的金属片 4 ，故连接部 3 的第一连接端 31 和第二连接端 32 部分的电阻值非常低。并且金属片 4 可在电热丝的发热部未卷绕前包扎固定，在具体的实施例中，金属片 4 可以将整个第一连接端 31 和第二连接端 32 完全包覆。
在本发明的优选实施例中，由于金属片 4 均匀包覆于第一连接端 31 和第二连接端 32 ，可以使得金属片 4 与驱动电路（图中未示）的焊接位置不固定，都可以保证连接部 3 与驱动电路的接触电阻稳定，即使金属片 4 的不同位置与驱动电路相焊接，连接部 3 与驱动电路的接触电阻仍是相同的。
实施例六，由于电热丝组件的阻值有限且驱动电路（图中未示）自身也能够适应一定的温度，通过改变金属片 4 的材质以及形状，在第一连接端 31 和第二连接端 32 包裹一层金属片 4 就可以将连接部 3 的电阻值降到合适的范围内。参照图 8 、图 9 和图 16 ，因此，金属片 4 呈单层管状包裹固定在发热部 2 两端的第一连接端 31 和第二连接端 32 表面且金属片 4 的展开形状为片状金属 7 ，牢靠地夹持固定在第一连接端 31 和第二连接端 32 上。相对于多层卷绕的结构在满足性能的同时简化第一连接端 31 和第二连接端 32 的结构，节约工艺步骤。
参照图 10 至图 15 以及图 17 、图 18 ，金属片 4 的展开形状还可以为'工'字型片状金属 8 或者'王'字型片状金属 9 ，该金属片 4 呈单层管状包裹固定在连接部 3 的第一连接端 31 和第二连接端 32 的表面，金属片 4 部分完全包裹住第一连接端 31 和第二连接端 32 ，作为将金属片 4 扎紧固定在第一连接端 31 和第二连接端 32 的紧固点，金属片 4 不完全包裹第一连接端 31 和第二连接端 32 位于紧固点之间的部分，金属片 4 之间可能的焊接区域包裹住，而其他部分不进行包裹，尽量减小第一连接端 31 和第二连接端 32 位置的横截面变化，保持电子烟内部结构的一致性。
实施例七，参照图 2 、图 7 、图 10 、图 12 ，电热丝组件还设置有为发热部 2 提供烟油的柱形导油绳 1 ，发热部 2 螺旋缠绕在柱形导油绳 1 上，柱形导油绳 1 与电子烟内设的储油部件相连通并直接接触到烟油，柱形导油绳 1 一般使用玻璃纤维线编织或者吸油棉等能够吸收引导烟油的材料制成。烟油通过柱形导油绳 1 进入到电热丝组件内被发热部 2 加热雾化生产烟雾供用户吸食，实现电子烟的功能。
参照图 19 ，本发明还提出一种电子烟，该电子烟采用了上述各个实施例中的电热丝组件。具体而言，该电子烟包括烟嘴 100 、储油套 200 、雾化芯 300 、隔油板 110 、通气管 210 以及电池组件（图中未示），储油套 200 为管状结构，烟嘴 100 连接固定在储油套 200 一端，电池组件连接在储油套 200 另一端并与雾化芯 300 电性连接，隔油板 110 设置在储油套 200 内靠近烟嘴 100 一端，雾化芯 300 设置在储油套 200 内远离烟嘴 100 一端，通气管 210 插设在隔油板 110 与雾化芯 300 之间形成供烟雾通过的通道。电热丝组件 310 设置在雾化芯 300 内，电热丝组件 310 的发热部 2 设置在雾化芯 300 内朝向烟嘴 100 的一侧，连接部 3 则设置在雾化芯 300 内朝向电池组件（图中未示）一侧。连接部 3 的第一连接端 31 和第二连接端 32 分别与雾化芯的电极组件相焊接并电性连接。电极组件与电池组件电性连接。由于连接部 3 上包裹有金属片 4 ，连接部 3 与电子烟的其他部件焊接相对容易。
参照图 20 ，本发明还提出了一种电子烟中电热丝组件的制造方法，该方法使用了第一支架 400 、第一固定件 700 、第一转动装置 420 、第二转动装置 430 、切断组件 460 、第二支架 500 、第二固定件 710 以及包裹金属片装置 510 等设备，在制造过程中，电热丝 5 从第二支架 500 进料通过包裹金属片装置 510 进入第二转动装置 430 等待与导油绳进行绕线作业；同时，电热丝 5 从第二支架 500 至第二转动装置 430 的运行方向设定为第一预置方向；导油绳 600 从第一固定件 700 上进料依次通过第一转动装置 420 、第二转动装置 430 ，电热丝 5 与导油绳 600 在第二转动装置 430 处完成绕线作业后共同向切断组件 460 运动并被切断组件 460 裁断完成相应的工序步骤，导油绳 600 在第一转动装置 420 、第二转动装置 430 以及切断组件 460 的运行方向设定为第二预置方向，切断组件的位置设定为第一预置位置。
本实施例记载的电子烟中电热丝组件的制造方法包括以下步骤：
S1 、将电热丝 5 绕成电热丝卷，对电热丝卷进行区域划分，其中该划分的区域包括若干个用于雾化烟油的发热部 2 和若干个连接部 3 ，连接部 3 包括位于发热部 2 两端的第一连接端 31 和第二连接端 32 ，第一连接端 31 、发热部 2 、第二连接端 32 区域依次排布；
S2 、将从电热丝卷中伸出的电热丝 5 的自由端沿第一预置方向输送，其中，第一预置方向为图 20 中箭头 A 所指方向；

S5 、在电热丝 5 的预设的切割点裁断电热丝 5 ，具体的，在第二预置方向的第一预设位置处设置用于对导油绳 600 及电热丝 5 同时进行裁切的切断组件 460 ，以形成电热丝组件。
其中，在步骤 S1 中：电热丝卷套设在设置于第二支架 500 上的第二固定件 710 上，第二固定件 710 能够相对第二支架 500 转动，实现将电热丝从第二固定件 710 中持续抽出送入包裹金属片装置 510 进行包裹金属片 4 作业。
在步骤 S2 中：通过第二牵引装置（图中未示）将电热丝卷的自由端朝第一转动装置 420 及第二转动装置 430 之间的位置输送，电热丝 5 首先进入包裹金属片装置 510 ，包裹好金属片 4 的电热丝 5 继续朝第一转动装置 420 及第二转动装置 430 之间的位置输送进行缠绕导油绳 600 作业。
步骤 S3 中使用包裹金属片装置 510 采用金属片包扎工艺将金属片 4 包扎固定在电热丝组件的第一连接端 31 和第二连接端 32 上，其中，步骤 S2 中的第一预置方向为电热丝 5 在包裹金属片装置 510 的进料方向（图 20 中箭头 A 所指方向），优选的，包裹金属片装置 510 可以使用包扎机来进行金属片 4 的包扎作业。电热丝 5 以设定的速度连续进入包扎机内，包扎机将金属片 4 依次包扎固定在电热丝 5 划分的规定区域上，完成包扎金属片 4 工序，形成包扎好金属片 4 的长串电热丝 5 ，然后被送入第二转动装置 430 进行下一步缠绕导油绳 600 作业。
步骤 S4 具体包括以下步骤：用于被电热丝 5 缠绕的导油绳 600 由套设在第一支架 400 的第一固定件 700 上的导油绳卷供应，第一固定件 700 在外力作用下能够相对第一支架 400 转动的同时能够围绕自身中轴线旋转，使得导油绳 600 能够被持续地从导油绳卷上被抽出且同时旋转。导油绳 600 的自由端在第一牵引装置 440 的施力作用下朝第二预置方向运动（图 20 中箭头 B 所指方向），以使缠绕在导油绳 600 上的发热部 2 随着导油绳 600 朝第二预置方向运动；其中，第二预置方向为导油绳 600 在第一转动装置 420 和第二转动装置 430 的进料方向。
在第一固定件 700 与第一预设位置之间设置有第一转动装置 420 及第二转动装置 430 ，第一转动装置 420 上设置有第一导油绳夹紧组件 490 ，第二转动装置 430 设置有第二导油绳夹紧组件 480 ，第二转动装置 430 的面向第一转动装置 420 的一端设置有电热丝夹紧装置 520 ，以使在电热丝夹紧装置 520 夹紧电热丝 5 自由端中的连接部 3 后随第一转动装置 420 及第二转动装置 430 转动并沿第二预置方向运动，而将发热部 2 呈螺旋状地缠绕在导油绳 600 上。
具体的，电热丝夹紧装置 520 设置在以导油绳 600 为圆心的一个圆周上，包裹好金属片 4 的电热丝 5 夹紧固定在电热丝夹紧装置 520 上并跟随第二转动装置 430 的旋转而围绕导油绳 600 旋转，从而将电热丝 5 上划分为发热部 3 的区域呈螺旋状缠绕在导油绳 600 上。
在电热丝 5 绕导油绳 600 旋转的同时，第一导油绳 600 夹紧装置和第二导油绳 600 夹紧装置同时夹紧导油绳 600 ，第一转动装置 420 和第二转动装置 430 同步旋转带动导油绳 600 旋转，第一牵引装置 440 驱动第一转动装置 420 和第二转动装置 430 沿第二预置方向运动，带动导油绳 600 在围绕自身旋转的同时沿第二预置方向运动，使得电热丝 5 呈螺旋状缠绕在导油绳 600 上。
具体的，第一牵引装置 440 采用步进电机作为动力牵引，电机与第一转动装置 420 及第二转动装置 430 传动连接，并通过步进电机的正转和反转带动第一转动装置 420 及第二转动装置 430 沿第二预置方向往复运动，而实现将导油绳 600 朝第二预置方向的持续输送。
同时，为了保证导油绳 600 在第一转动装置 420 和第二转动装置 430 内旋转的一致性，第一转动装置 420 及第二转动装置 430 由同一个动力装置 470 驱动作同步旋转，防止导油绳 600 由于第一转动装置 420 和第二转动装置 430 之间旋转速度不一致而发生周向扭曲。
在另一具体实施例中，电热丝组件的制造方法包括以下步骤：
S1 、将电热丝 5 绕成电热丝卷，对电热丝卷进行区域划分，其中该划分的区域包括若干个用于雾化烟油的发热部 2 和若干个连接部 3 ，连接部 3 包括位于发热部 2 两端的第一连接端 31 和第二连接端 32 ，第一连接端 31 、发热部 2 、第二连接端 32 区域依次排布；
S2 、将从电热丝卷中伸出的电热丝 5 的自由端沿第一预置方向输送，其中，第一预置方向为图 20 中箭头 A 所指方向；
S3 、在电热丝 5 的输送路径上对第一连接端 31 和第二连接端 32 包裹电阻率低于电热丝 5 的电阻率的金属片 4 ；
S4 、将发热部 2 呈螺旋状缠绕在导油绳 600 上且电热丝 5 连同导油绳 600 一起朝第二预置方向运动，其中，第二预置方向为图 20 中箭头 B 所指方向；
S5 、在电热丝 5 的预设的切割点裁断电热丝，即缠绕完成所述电热丝 5 后在所述第一转动装置 420 和第二转动装置 430 之间切断所述电热丝；
S6 ：电热丝 5 的发热部 2 呈螺旋状缠绕在导油绳 600 上后连同导油绳 600 在第二转动装置 430 的带动下继续朝第二预置方向运动至第一预设位置处，设置在第一预设位置处的切断组件 460 对导油绳 600 上设定的切割点进行裁切，形成电热丝组件成品。即该电热丝组件的制造方法为在缠绕完成电热丝后先切断电热丝后切断导油绳。
在一具体实施例中，在第一预设位置的远离第二转动装置 430 的一侧设置有第三导油绳夹紧组件 450 ，以使在裁切导油绳 600 及电热丝 5 时第二导油绳夹紧组件 480 与第三导油绳夹紧组件 450 共同夹紧导油绳 600 及电热丝 5 ，避免因为导油绳 600 及电热丝卷曲而出现裁切位置不准确的现象。并且导油绳 600 夹持并与第二转动装置 430 沿背离第二预置方向运动时第三导油绳夹紧组件 450 夹紧加工成型的电热丝组件，避免出现电热丝组件失去支撑后掉落损伤。
在一具体实施例中，参照附图 20 ，为导油绳 600 在绕线时能够带有适宜的张力，在第一支架 400 与第一转动装置 420 之间设置有张力器 410 ，从而使电热丝 5 在导油绳 600 上绕制的线圈松紧适宜，紧固饱满，保证了发热丝组件的发热部 2 的技术指标的一致性。
采用本发明的电热丝组件的结构有以下优点，本发明的电热丝组件在制造组装过程中不需要使用到焊接或者铆接等复杂工艺，可以采用自动化生产工艺使用金属包扎技术将低电阻率的金属片 4 包扎固定在电热丝 5 上，整个生产过程无需人工干预，使得该电热丝组件的生产效率大大提高，节约了成本，且大批量生产出来的电热丝组件电阻值稳定，批量生产的一致性好。同时由于本发明的金属片 4 采用低电阻率的金属或者合金，使得电热丝组件的连接部 3 的电阻值非常低。
以上仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
