实施例一
如图1至图4所示，其为本申请的一种实施例的雾化结构。
如图1至图4所示，该雾化结构，包括雾化管壳1、雾化芯2以及发热组件3，所述雾化管壳1上形成有贯穿所述雾化管壳1的气腔11以及与所述气腔11连通的进油孔12，所述雾化芯2成型在所述气腔11的腔壁上并与所述进油孔12位置对应，所述雾化芯2上形成有通气孔21，所述通气孔21与所述气腔11连通形成雾化通道，所述发热组件3设于所述雾化芯2上，所述发热组件3用于对所述雾化芯2进行加热。
该雾化结构，采用雾化管壳1与雾化芯2一体成型的结构，具体为将雾化管壳1先预置在成型模具中，然后通过成型的方式在雾化管壳1的气腔11腔壁成型雾化芯2，使雾化芯2贴合于所述雾化管壳1的气腔11的腔壁，从而使得该雾化结构可在不使用硅胶密封的前提下实现密封，同时可有效避免漏油现象的发生。
此外，所述雾化芯2为带有通气孔21的管状结构，所述雾化芯2的内表面即为雾化面，通气孔21与气腔11直接贯通形成雾化通道，使得所述雾化芯2的雾化面与雾化通道直接贯通，减少抽吸阻力。而雾化管壳1上形成有连通外部储油腔和雾化芯2的进油孔12，可使外部储油腔的烟油通过进油孔12渗透到雾化芯2中，若所述发热组件3通电，则雾化芯2内侧的烟油将被雾化，使得产生烟雾通过雾化通道供人抽吸。
需要说明的是，在电子烟领域中，部分部件名称目前尚未统一，如，雾化管壳也可叫做雾化管壳，发热组件也可叫做发热组件，其以实际情况为准。
优选地，所述雾化芯2可通过注射成型、压铸成型、挤出成型或注浆成型的方式形成在所述气腔11的腔壁上。
所述雾化芯2成型在所述气腔11的腔壁上，包括：所述雾化管壳1烧结成型后预置在成型模具中；所述雾化芯2通过注射成型、压铸成型、挤出成型或注浆成型的方式成型在所述气腔11的腔壁上；对成型的所述雾化芯2进行烧结，使所述雾化芯2与所述雾化管壳1一体。
进一步地，所述雾化管壳1的一端靠近电子烟的吸嘴位置，相对的另一端靠近电子烟的烟杆，所述雾化芯2位于所述陶瓷管壳1靠近烟杆的一侧。
在一实施例中，所述雾化芯2与所述气腔11的腔壁连接，既可以是雾化芯2的外周面整体密封贴合于所述气腔11的腔壁上，使得外部储油腔中的烟油可以短距离到达雾化芯2；也可以是所述雾化芯2在所述气腔11的延伸方向上的靠近吸嘴的一端密封贴合于所述气腔11的腔壁上，或是所述雾化芯2的两端均密封贴合于所述气腔11的腔壁上，以使得雾化芯2固定贴合于所述气腔11的腔壁的同时，防止烟油被抽吸到。
在一实施例中，如图4所示，所述气腔11包括小径段气腔111、大径段气腔112以及连接在所述小径段气腔111与所述大径段气缸112之间的过渡气腔113，所述小径段气腔111的截面面积小于所述大径段气腔112的截面面积，所述过渡气腔113的截面面积由靠近所述大径段气腔12一侧向靠近所述小径段气腔11一侧逐渐减小，所述进油孔21通过所述雾化芯2与所述大径段气腔112连通，这样有利于所述雾化管壳1吸收烟雾中因冷凝形成的水份，可对烟雾进行干燥，提高烟雾的抽吸口感。
进一步地，所述雾化芯2成型在所述大径段气腔112的腔壁上，以使外部储油腔的烟油通过进油孔12可有效渗透到雾化芯2中。
在一实施例中，如图4所示，所述过渡气腔113的腔壁形成有弧面。出于对所述过渡气腔113的的截面面积的限定，使得所述弧面的横截面积也将沿着抽 吸方向(即由所述大径段气腔12向所述小径段气腔11延伸的方向)逐渐减小，有利于吸收雾化通道中因冷凝形成的烟油，提高抽吸口感。
在一实施例中，如图3及图4所示，所述雾化管壳1包括管壳本体部13以及设置在所述管壳本体部13的一端用于连接烟杆的烟杆连接部14，所述气腔11贯穿所述管壳本体部13与部分所述烟杆连接部14，所述烟杆连接部14包括多个凸起141，相邻两个所述凸起141之间形成有凹槽142。通过设置多个所述凸起141与凹槽142结构，以实现所述雾化管壳1与烟杆之间的连接，同时可实现所述雾化管壳1与烟杆之间的密封，使所述雾化管壳1与烟杆之间围成一储油腔。

在一实施例中，如图3及图4所示，所述进油孔12设置在所述管壳本体部13靠近所述烟杆连接部14的一侧。这样，当烟油量较少的时候，可以保证烟油还能浸渗到雾化芯2上。
在一实施例中，如图3及图4所示，所述进油孔12设置有多个。多个所述进油孔沿12所述雾化管壳1的周向设置，以保证在烟油量较少的时候，烟油仍能浸渗到雾化芯2上。
在图未示出的实施例中，多个所述进油孔也可沿所述雾化管壳的轴向设置， 从而使得雾化芯接触到烟油的长度加长，使烟油浸渗更充足，避免产生干烧现象。此外，还可将多个所述进油孔沿矩阵的方式设置在所述雾化管壳上，这样既可保证在烟油量较少的时候，烟油仍能浸渗到雾化芯2上，还可使烟油浸渗更充足，避免产生干烧现象。
在一实施例中，如图1至图4所示，所述雾化管壳1为陶瓷管壳(也可称为陶瓷管)，所述陶瓷管壳由致密陶瓷制成。
所述雾化芯2由多孔陶瓷注射成型，即所述雾化芯2为多孔陶瓷，所述多孔陶瓷的孔隙率为40-70％，所述多孔陶瓷的孔径为5-40μm，以保证烟油的浸渗程度。
在一实施例中，如图1及图2所示，所述发热组件3包括发热丝31，所述发热丝31嵌设在所述雾化芯2上。具体地，所述发热丝31嵌设在所述雾化芯2的雾化面上，所述雾化芯2的雾化面与雾化通道贯通，以对所述雾化芯2的雾化面进行加热，使所述雾化面的烟油被雾化，而产生烟雾可通过雾化通道直接供人抽吸，从而减少抽吸阻力。
优选地，所述发热丝31为双发热丝。
在一实施例中，如图2所示，所述雾化结构还包括设于所述雾化管壳1与部分所述雾化芯2之间的导油棉4。优选地，所述导油棉4可设置有一层或多层。
在对电子沿进行抽吸时，储油腔中的烟油通过进油孔12先流经所述导油棉4，然后进一步渗透扩散到多孔陶瓷的雾化芯2中，保证烟油的持续供给。
