具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
下面对本申请的实施例进行详细描述。
电子烟中的雾化器，包括雾化芯和储液腔体。雾化芯包括加热部件和导液部件，加热部件与电源电连接，导液部件从储液腔体中吸收烟油，加热部件利用电能发热，对导液部件中的烟油进行雾化，以产生烟雾。目前，导液部件可以采用陶瓷材质，但是，陶瓷材质的导液部件，在生产加工过程需要加入特殊材质的添加剂，加热部件对其加热雾化时，残留的添加剂也会被雾化，同时陶瓷的细微粉尘也可能挥发出来，导致电子烟安全性较差；同时，陶瓷材质的导液部件具有多孔和微孔特质，会对电子烟的芳香味道产生吸附作用，由此，导致电子烟口味较差。
为了提供口味和安全性较好的电子烟，则导液部件可以采用棉纤维束，其纯天然的材质，没有添加剂。但是，棉纤维束材质偏软，导液部件与加热部件结合不稳固，加热时导液部件受热不均匀，导致对烟油的雾化的一致性和细腻度较差，同时容易导致液体泄漏；并且，批量生产过程时也很难以保证产品的一致性。
为了解决上述问题，本申请提供了口味、安全性、雾化细腻度、成型性、稳固性及一致性都很好雾化芯，下面结合附图进行详细说明。
图1为本申请提供的一种雾化芯结构示意图，雾化芯包括：加热部件1和导液部件2，加热部件1包括加热金属部11和接电金属部12，加热金属部11为圆柱形，对棉纤维进行加工获得短棉纤维，短棉纤维的长度比棉纤维短，将短棉纤维作为导液部件2与加热金属部11一体成型。
接电金属部12被配置为接入电源状态下，给加热金属部11提供电能，加 热金属部11被配置为利用电能发热，对导液部件2中的烟油进行雾化。
导液部件2的材质采用短棉纤维，对普通的棉纤维进行加工处理可获得短片纤维，短棉纤维是长度很短的棉纤维，纯天然材质，无添加剂，对导液部件2中的烟油进行雾化时，不会产生杂质，口味好、安全性高。
对普通的棉纤维进行加工处理获得短棉纤维，可采用多种可行的方式。例如，将棉纤维梳理成长条棉束，压实固定。用自动化裁切机对长条棉束进行机械裁切，再进行均匀化处理，使其蓬松不结团，再通过鼓风配合筛网，剔除不符合长度要求的棉纤维，从而获得短棉纤维。再例如，将棉纤维放入粉碎机器，对粉碎后的棉纤维进行均匀化处理使其不结团，再通过鼓风配合筛网，选出符合长度要求的短棉纤维，将长度过长的棉纤维再次放入粉碎机器进行重复加工，直至获得符合长度要求的短棉纤维。当然，还可以采用其他可行的方式对棉纤维进行加工，获得短棉纤维，这里不再进行赘述。
短棉纤维的长度比普通的棉纤维的长度短，能够采用加工工艺形成均匀分布的吸收烟油的结构，相比传统的棉纤维束，密度更高，硬度更大，孔隙大小一致性也更高。导液部件2与加热金属部11一体成型，加热金属部11对导液部件2中的烟油进行雾化时，该结构使得导液部件2内部受热均匀，对烟油的雾化细腻度较好。
加热金属部11为圆柱形，圆柱形结构能使得外部气流从下方穿过加热部件11的内孔，与雾化后的烟气一并被吸出，雾化芯内气流通道更顺畅。同时，圆柱形的加热金属部11结构更稳固，组装更方便。
电子烟通常采用与香烟外观相同的圆柱形，雾化器也大都制造成圆柱形以匹配电子烟的形状，雾化芯的加热金属部11采用圆柱形，能够更好的适配电子烟内腔的形状。并且，该结构与传统的金属丝结构相比更加稳定，坚固度高，难以产生形变；受热面积大，雾化效果好；更易组装，批量生产可以实现高度一致性。
在加工工艺方面，导液部件2与加热金属部11一体成型，雾化芯的成型性，稳固性，外观尺寸的一致性都很好。通过结构设计，使导液部件2与加热金属部11更容易装配，降低生产难度，提高生产效率，提升产品质量的稳定性和一致性。
在一个示例中，导液部件2所采用的短棉纤维的长度小于10mm。可以理解的是，若采用较长的棉纤维，则由于棉纤维材质偏软的特性，内部孔隙较大，均匀性差。因此，导液部件2所采用的短棉纤维，将普通的棉纤维通过工艺加工变短，使其长度小于10mm，这样导液部件2与加热金属部11一体成型后，导液部件2内部空隙大小一致性高，加热雾化时导液部件2受热均匀，对烟油的雾化细腻度好。
在一个示例中，加热金属部11为镂空的金属箔片。如图2所示，加热金属部11圆柱形的金属箔片呈回形镂空结构。当然，加热金属部11的金属箔片还可以采用除了回形镂空结构以外的多种镂空结构。例如：长方形镂空结构，三角形镂空结构，螺旋形镂空结构等。
在图2和图5所示的示例中，加热金属部11的回形镂空结构包括两端的弯折部111，及弯折部之间的非弯折部112。弯折部111与非弯折部112单位长度的金属面积不完全相同。
如图2所示，加热金属部11回形结构一端的弯折处111导电面积大于非弯折部112的导电面积，由图2所示，弯折处111的单位长度的金属面积较大，电阻小，主要用于导电和塑形。非弯折处112单位长度的金属面积较小，电阻大，用于发热雾化。加热雾化时，导液部件2远离中心的温度要求偏低，中间的温度要求偏高。
如图5所示的回形结构中，两端的弯折处111的导电面积均大于非弯折部112的导电面积，即两端弯折处111的电阻均小于非弯折处112的电阻。可选的，回形结构两端的弯折处的电阻可以相同，也可以不同。
在一个示例中，如图2所示，加热金属部11呈回形镂空结构，接电金属部12包括金属丝部和金属片部。其中，接电金属部12的金属片部至少部分与导液部件2一体成型，接电金属12的金属丝部外露出导液部件2。导液部件2与加热金属部11一体成型的结构图如图3和图4所示，图4为透视图。
在一个示例中，如图5所示，接电金属部12的两个电极都是金属箔片。两个电极都为半圆弧形，两个所述金属箔片形成可支撑所述加热金属部的类圆形底座。接电金属部12采用上述结构设计，与采用金属丝相比，能提供更大的接触面积，接入电源的结构更稳定可靠。
接电金属12接入电源，给加热金属部11提供电能，加热金属部11利用电能发热，对导液部件2吸收的烟油进行雾化。在一个示例中，加热金属部11与接电金属部12可以焊接接触。此时，加热金属部11与接电金属部12可以采用相同材质的金属，也可以采用不同材质的金属。在另一个示例中，加热金属部11与接电金属部12还可以一体成型。一体成型的加热部件1结构更稳定。
加热金属部11呈电阻非均匀回形镂空结构，接电金属部12为半圆弧形金属箔片时，导液部件2与加热金属部11一体成型的结构图如图6和图7所示，图7为透视图。
与图2-图7所示的加热金属部11的回形镂空结构不同，图8和图11所示的加热金属部11的回形镂空结构中，两端的弯折部113与非弯折部114单位长度的金属面积均相同，即图8和图11所示的加热金属部11的回形镂空结构各位置处的导电面积都相同，因此，加热金属部11的回形镂空结构各位置处的电阻都相同。
在一个示例中，如图8所示，加热金属部11呈电阻均匀的回形镂空结构，接电金属部12包括金属丝部和金属片部。其中，接电金属部12的金属片部至少部分与导液部件2一体成型，接电金属12的金属丝部外露出导液部件2。导液部件2与加热金属部11一体成型的结构图如图9和图10所示，图10为透视图。
在另一个示例中，如图11所示，加热金属部11呈电阻均匀的回形镂空结构，接电金属部12的两个电极都是金属箔片。两个电极都为半圆弧形，两个所述金属箔片形成可支撑所述加热金属部的类圆形底座。接电金属部12采用上述结构设计，与采用金属丝相比，能提供更大的接触面积，接入电源的结构更稳定可靠。
接电金属12接入电源，给加热金属部11提供电能，加热金属部11利用电能发热，对导液部件2吸收的烟油进行雾化。在一个示例中，加热金属部11与接电金属部12可以焊接接触。此时，加热金属部11与接电金属部12可以采用相同材质的金属，也可以采用不同材质的金属。在另一个示例中，加热金属部11与接电金属部12还可以一体成型。一体成型的加热部件1结构更稳 定。
加热金属部11呈电阻均匀的回形镂空结构，接电金属部12为半圆弧形金属箔片时，导液部件2与加热金属部11一体成型的结构图如图12和图13所示，图13为透视图。
在一个示例中，如图14所示，加热金属部11为弹簧状金属丝。该弹簧状金属丝也呈圆柱形。圆柱形结构能使得外部气流从下方穿过加热部件1的内孔，与雾化后的烟气一并被吸出，雾化芯内气流通道更顺畅。同时，圆柱形的加热金属部11结构更稳固，组装更方便。
图14所示的示例中，加热金属部11包括第一功能部115及第二功能部116，第一功能部115的电阻值小于第二功能部116的电阻。
如图14所示，加热金属部11远离中心的少量金属丝可设置为第一功能部115，靠近中心的金属丝可设置为第二功能部116。可选的，如图15所示，还可以在远离中心的两端都设置第一功能部115，第二功能部116位于两个第一功能部115之间。可选的，在远离中心的两端都设置第一功能部115时，两端的第二功能部116的电阻可以相同，也可以不同。
可选的，第一功能部115采用电阻小的材质，主要用于导电和塑形。第二功能部116采用电阻大的材质，用于发热雾化。可选的，第一功能部115可采用镍；第二功能部116可采用镍铬合金、铁铬合金、不锈钢任意一种。加热雾化时，导液部件2远离中心的温度要求偏低，中间的温度要求偏高。
在一个示例中，如图16所示，接电金属部12和加热金属部11的两个连接节点A和B位于加热金属部11的不同侧。在另一个示例中，如图17所示，接电金属部12和加热金属部11的两个连接节点C和D位于加热金属部11的同一侧。图11所示的结构，在导液部件2于加热金属部11一体成型加工时，避免短棉纤维被接电金属部12阻挡，影响一体成型的效果。
在一个示例中，加热金属部11呈弹簧状金属丝结构，接电金属部12为金属丝时，加热金属部11与接电金属部12可焊接接触。导液部件2与加热金属部11一体成型的结构图如图18、图19和图20所示，图19和图20为透视图，图19中接电金属部12和加热金属部11的两个连接节点A和B位于加热金属部11的不同侧，图20中接电金属部12和加热金属部11的两个连接节点A 和B位于加热金属部11的同一侧。
在一个示例中，如图3、图6、图9及图18所示，加热金属部件11的一部分从导液部件2中空的内边沿露出。另一个示例中，加热金属部件11全部嵌入导液部件2内部。可以理解的是，加热金属部件11的一部分从导液部件2中空的内边沿露出时，更有利于加热金属部件11给导液部件2加热雾化时进行散热。
在一个示例中，雾化器包括本申请上述内容所述的雾化芯，以及储液腔体。
在一个示例中，所述电子烟包括本申请上述内容所述的雾化器。
