具体实施方式
现在结合附图对本发明作详细的说明。此图为简化的示意图，仅以示意方式说明本发明的基本结构，因此其仅显示与本发明有关的构成。
实施例一
请参阅图1、图2，本发明实施例一提供了一种电子烟，该电子烟包括烟弹10以及与烟弹10电性连接的电源装置20，工作时，电源装置20向烟弹10供电，从而使得存储于烟弹10内的烟液雾化生成烟雾，烟雾供用户吸食。
请参阅图3、图4，烟弹10包括具有储液腔110的烟弹壳体11、用于密封储液腔110的密封件12以及安装在密封件12上的第一电极13和第二电极14，密封件12上远离储液腔110的端面上分别开设有用于安装第一电极13的第一盲孔121和用于安装第二电极14的第二盲孔122，密封件12由弹性材料制成，注液针头经由所述第一盲孔121及所述第二盲孔122中的至少一个的孔壁刺穿密封件12后与储液腔110连通以向储液腔110内注液，注液完毕后，拔出所述注液针头，密封件12在刺穿位置形成自密封，然后通过第一电极13封堵第一盲孔121，通过第二电极14封堵第二盲孔122。
本发明的烟弹10，密封件12可以被所述注液针头刺穿，以方便通过所述注液针头向储液腔110内注入烟液，并且在拔出所述注液针头后，密封件12上被刺穿位置能够自动恢复以再次密封储液腔110，防止注液完毕后储液腔110内的烟液发生泄漏。另外，注液完毕后，第一盲孔121及第二盲孔122分别被第一电极13及第二电极14封堵，如此，即使储液腔110内的烟液经由刺穿位置泄漏，泄漏的烟液也能够被第一电极13和/或第二电极14密封，进一步防止了烟液泄漏，避免因烟液泄漏而对电源装置20造成腐蚀。
在一个具体的实施方式中，密封件12可以由具有弹性变形能力的软性材料制成，可以是高弹态聚合物，例如，橡胶或硅胶。可以理解地，在其他实施方 式中，密封件12还可以由自愈合材料制成，因此，密封件12可以被尖锐的物体(例如，注液针头)刺穿，且在尖锐的物体拔出后，可以自动恢复后再次密封。密封件12的作用在于密封储液腔110，防止储液腔110内的烟液在运输、存储或者使用过程中泄漏。并且，密封件12还用于烟弹10组装完成后，通过所述注液针头刺穿密封件12，向储液腔110内注入烟液，并在所述注液针头拔出后，自动恢复，再次密封储液腔110。
另外，第一盲孔121和第二盲孔122的设置，一方面可分别供第一电极13及第二电极14安装，另一方面，盲孔减薄了密封件12在刺穿位置的厚度，使得所述注液针头可以更容易地刺穿密封件12，而密封件12的其余部分仍保有较大的厚度，使得密封件12与烟弹壳体11之间的密封连接更稳定，防止储液腔110内的烟液经由密封件12与烟弹壳体11的连接处泄漏。
在一个具体的实施方式中，注液时，所述注液针头经由第一盲孔121的底壁刺穿密封件12后与储液腔110连通以进行注液操作，为了保证储液腔110内的气压平衡，即保证注液操作的同时，储液腔110内的空气自动排出，第二盲孔122的孔壁上开设有切口，该切口在未注液状态下能够自密封，而在注液状态下，储液腔110内的压力增加，该切口能够在压力作用下被顶开，储液腔110内的空气能够经由被顶开的切口排出。可以理解地，在其他实施方式中，所述注液针头经由第二盲孔122的孔壁刺穿密封件12以实现注液，或者，注液针头有两个，两个注液针头同时经由第一盲孔121的孔壁以及第二盲孔122的孔壁刺穿密封件12以实现注液，此时，为了使储液腔110内的空气排出，在烟弹壳体11相对密封件12的一端开设一与储液腔110连通的通孔，储液腔110内的空气在注液时由该通孔排出。另外，所述注液针头还可以经由第一盲孔121和/或第二盲孔122的侧壁刺穿密封件12以实现注液，所述注液针头于盲孔内的刺 穿位置并不做限定。需要说明的是，为了避免储液腔110内的烟液从烟弹10的排气端泄漏，注液过程中，只需将烟弹10的排气端调整至烟弹10的上方的状态即可。
请再次参阅图3、图4，烟弹10还包括收容于储液腔110内的雾化头15，雾化头15包括具有雾化腔150的雾化管151以及收容于雾化腔150内的加热结构152，雾化管151与密封件12连接，加热结构152具有吸收烟液的能力，且通电后能够产生热量。加热结构152具有延伸至储液腔110外部的两个引脚1523，且两个引脚1523上伸出至储液腔110外部的一端均折弯设置，其中一个引脚1523上折弯的一端伸入至第一盲孔121内，且被第一电极13挤压固定在第一盲孔121的侧壁上，另一个引脚1523上折弯的一端伸入至第二盲孔122内，且被第二电极14挤压固定在第二盲孔122的侧壁上。如此，实现加热结构152的两个引脚1523与第一电极13及第二电极14电性连接功能的同时，也实现了对加热结构152的固定作用，并且，当用户需要拆卸或更换加热结构152时，只需取下第一电极13和第二电极14，从而解除对引脚1523的挤压作用，便可轻松取下加热结构152，操作简单、方便，提升了用户的使用体验。另外，加热结构152的两个引脚1523并未浸泡在储液腔110内，避免了引脚1523被烟液腐蚀。
本实施方式中，加热结构152为陶瓷加热体，即，陶瓷加热体具有吸收烟液的能力的同时，还具有加热烟液的能力。可以理解地，在其他实施方式中，加热结构152包括相互接触的导液件1521和加热件1522，导液件1521为棉花、海绵、纤维绳、多孔陶瓷或多孔石墨等具有吸收烟液能力的元件，加热件133为加热片、加热网或加热棒等通电后具有加热烟液能力的元件，还可以理解地，加热结构152还可以是超声加热装置或加热管等，此处不做限定。
在一个具体的实施方式中，烟弹壳体11大致呈下端具有开口的中空筒状结构，烟弹壳体11为扁平状结构，其做为烟弹10的外形轮廓，可有效防止烟弹10滚动，避免了烟弹10跌落。储液腔110由烟弹壳体11的内腔构成，烟液存储于储液腔110内。密封件12密封烟弹壳体11的下端开口。烟弹壳体11由透明或半透明材料制成，使得用户能够透过烟弹壳体11观察到储液腔110内的烟液量，方便用户及时注液操作。本实施方式中，烟弹壳体11由半透明的塑料制成。
另外，烟弹壳体11的上端面的中心处沿烟弹本体11的轴向向下延伸形成通气管111，通气管111的上下两端贯通设置，且通气管111的上端贯通烟弹壳体11的上端面形成出烟口，密封件12相对所述出烟口位于烟弹壳体11的另一端，另外，通气管111的下端与雾化腔150连通，以使得雾化腔150内的烟雾经由通气管111进入至用户口中。
密封件12大致呈块状结构，密封件12收容于烟弹壳体11的下端内以封闭储液腔110，具体地，储液腔110由烟弹壳体11的内壁、通气管111的外壁以及密封件12的上端面之间围设的空间构成。密封件12的中心处沿密封件12的轴向开设有通孔123，通孔123贯通密封件12的上、下两端面，雾化管151与通孔121连接，加热结构152的两个引脚1521穿过通孔121后伸出至储液腔110的外部。另外，第一盲孔121与第二盲孔122设置在密封件12的下端面上且对称设置在通孔123的两侧，即，第一盲孔121与第二盲孔122相对烟弹壳体11的中心轴对称设置。
雾化管151大致呈两端贯通的中空筒状结构，雾化腔150由雾化管151的内腔形成，雾化管151的下端密封插入至通孔123内，雾化管151的上端收容于储液腔110内，雾化管151的侧壁上开设有进液口1511，进液口1511与储液 腔110及雾化腔150均连通。使用时，储液腔110内的烟液经由进液口1511进入至雾化腔150内进而与加热结构152接触，而后在加热结构152的加热作用下生成烟雾。
另外，雾化头15还包括固定套153，固定套153夹设在雾化管151的内周面与加热结构152的外周面之间，固定套153由耐高温的硅胶或橡胶材料制成，通过设置固定套153，增加了加热结构152与雾化管151之间的连接稳定性，防止加热结构152与雾化管151相脱离。同时，固定套153的侧壁上开设有连通孔1531，连通孔1531与进液口1511及加热结构152均连通，以使得储液腔110内的烟液依次经由进液口1511及连通孔1531后与加热结构152接触。
在一个具体的实施方式中，烟弹10还包括底座16，底座16盖设在烟弹壳体11的下端且位于储液腔110的外部，底座16的上端面与密封件12的下端面相抵持，从而对由弹性材料制成的密封件12起到支撑作用，防止密封件12轻易变形而影响对烟液的密封效果。另外，底座16与烟弹壳体11之间可通过螺纹连接、卡接、插接或磁性连接等方式连接，此处不做限定。
请参阅图4，在一个具体的实施方式中，底座16的下端面凹陷形成有第一安装槽161和第二安装槽162，第一安装槽161与第一盲孔121相对应，且第一安装槽161的尺寸大于第一盲孔121的尺寸，第二安装槽162与第二盲孔122相对应，且第二安装槽162的尺寸大于第二盲孔122的尺寸。第一电极13与第二电极14均呈“凸”字形结构，第一电极13的上端穿过第一安装槽161的底壁后紧密插入至第一盲孔121内，第一电极13的下端收容于第一安装槽161内且与第一安装槽161的底壁相抵持，第二电极14的上端穿过第二安装槽162的底壁后紧密插入至第二盲孔122内，第二电极14的下端收容于第二安装槽162内且与第二安装槽162的底壁相抵持，如此，限制了第一电极13于第一盲孔121 内的插入深度以及第二电极14于第二盲孔122内的插入深度，避免因第一电极13及第二电极14插入过深而将刺穿位置顶开，进而导致烟液泄漏的情况发生。需要说明的是，当第一电极13与第二电极14安装到位后，第一电极13的下端面及第二电极14的下端面均与底座16的下端面齐平，使得烟弹10更加美观。可以理解地，在其他实施方式中，第一安装槽162与第二安装槽162还可以均省略，此时，第一电极13的上端穿过底座16后紧密插入第一盲孔121内以封堵第一盲孔121，第一电极13的下端位于底座16的外部并与底座16的下端面相抵持，第二电极14的上端穿过底座16后紧密插入第二盲孔122内以封堵第二盲孔122，第二电极14的下端位于底座16的外部并与底座16的下端面相抵持。另外，为实现电性隔离，避免短路，底座16由绝缘的硬质材料制成，本实施方式中，底座16由塑料制成。
另外，底座16的下端面沿底座16的轴向开设有与雾化腔150连通的感应通孔163，感应通孔163有一个且位于底座16的中心处，第一安装槽161与第二安装槽162对称设置在感应通孔163的两侧。在一个具体的实施方式中，底座16的下端面上还开设有与雾化腔150连通的进气孔，所述进气孔位于感应通孔163的一侧。
可以理解地，在其他未示出的实施方式中，底座16还可以省略，此时，第一电极14全部插入第一盲孔121内，第二电极15全部插入第二盲孔122内。如此，只需满足第一电极14至少部分紧密插入第一盲孔121内且插入的部分封堵第一盲孔121以及第二电极15至少部分紧密插入第二盲孔122内且插入的部分封堵第二盲孔122即可。
在一个具体的实施方式中，烟弹10还包括分隔组件，所述分隔组件包括套管17和提拉杆18，套管17呈下端具有开口的中空筒状结构，套管17沿雾化头 15的轴向可滑动地套设在雾化管151的外部，提拉杆18呈杆状结构且可滑动地穿设在通气管111的内部，提拉杆18的下端与套管17的上端连接，提拉杆18的上端穿过通气管111的上端开口后延伸至烟弹壳体11的外部。烟弹10出厂时，套管17对应进液口1511套设在雾化管151的外部以关闭进液口1511，防止储液腔110内的烟液经由进液口1511进入至雾化头15内，从而将烟液与外界空气隔离，防止运输过程中由于温度、气压变化导致烟液进入到雾化头15内与空气接触发生变质，也能进一步防止雾化头15因进入过多烟液而发生烟液泄漏的情况。当用户使用时，向上提拉所述提拉杆18，套管17在提拉杆18的带动下一同向上移动进而打开进液口1511，使得烟液通过进液口1511与雾化腔150连通，当继续向上提拉所述提拉杆18至套管17的上端面与通气管111的下端面相抵持时，提拉杆18能够与套管17相脱离，进而能够从通气管111内被抽出，通气管111打开，此时，雾化腔150通过套管17与通气管111的内腔连通。
可以理解地，套管17由硅胶或橡胶材料制成，以方便烟弹10出厂时实现对进液口1511的密封作用，而且，方便套管17发生变形以使其与提拉杆18相脱离。本实施方式中，套管17与提拉杆18一体成型，套管17与提拉杆18的连接部位被拉断进而与提拉杆18相脱离。
另外，套管17的上端面上沿套管17的轴向向上延伸形成连接部171，连接部171套设在通气管111上，使得套管17与通气管111相连接，可以防止烟液通过套管17和通气管111之间的间隙泄漏，且在套管17的移动过程中，起到导向作用。
请参阅图3，电源装置20包括电池壳21以及安装在电池壳21上的电池22和传感器23。
在一个具体的实施方式中，电池壳21大致呈上端具有开口的中空筒状结构，电池壳21的内部沿电池壳21的径向设置有隔板211，隔板211将电池壳21的内腔隔设为用于安装电池22的电池安装槽212以及用于安装烟弹10的烟弹安装槽213，电池安装槽212位于电池壳21远离开口的一端。烟弹10通过电池壳21的开口与电池壳21连接，具体地，烟弹壳体11的相对两侧设置有卡嵌凸起113，烟弹安装槽213的槽壁上对应卡嵌凸起113开设有卡嵌凹槽2131，当烟弹10插入电池壳21内时，卡嵌凸起113与卡嵌凹槽2131相配合，以稳固烟弹10与电源装置20的连接。
另外，当烟弹10与电源装置20安装到位后，底座16的下端面与隔板211的上端面之间形成一间隙2111，该间隙2111与所述进气孔及外界大气均连通，以方便外部气体进入烟弹10的内部。
隔板211上还分别安装有第一极柱2112和第二极柱2113，第一极柱2112与电池22的正、负极中的一个电极电性连接，第二极柱2113与电池22的正、负极中的另一个电极电性连接，当烟弹10与电源装置20安装到位后，第一极柱2112与第一电极13接触并电性导通，第二极柱2113与第二电极14接触并电性导通，从而实现电池22向加热结构152供电的功能。
另外，隔板211的上端面对应感应通孔163凸设有安装柱2114，安装柱2114上开设有感应通道2115，感应通道2115的上端贯通安装柱2114的上端面，感应通道2115的下端贯通隔板211的下端面。第一极柱2112与第二极柱2113对称设置在安装柱2114的两侧，即，第一极柱2112与第二极柱2113相对烟弹壳体11的中心轴对称设置，如此，当烟弹10安装到电源装置20上时，无需考虑正负极性，达到正反插接均可以使用的效果。具体地，当烟弹10与电源装置20处于第一连接状态时，第一极柱2112与第一电极13接触并电性连接，当烟弹 10与电源装置20处于第二连接状态时，第一极柱2113与第二电极14接触并电性连接，本实施方式中，所述第一连接状态转变为第二连接状态是由所述电源装置20相对烟弹10转动180°得到，从而实现正反插均能电性导通的目的。传感器23安装在隔板211的下端且关闭感应通道2115，传感器23的感应端与感应通道2115相连通。当烟弹10与电源装置20安装到位时，安装柱2114部分插入底座16内，且感应通道2115与感应通孔163相连通。
在一个具体的实施方式中，电源装置20还包括电路板，电池22以及传感器23均与所述电路板电性连接，传感器23位压力传感器。用户进行抽烟操作时，感应通道2115内因抽吸作用产生负压，传感器23感应到感应通道2115内的气压变化并将该气压变化信号传递给所述电路板，所述电路板接收到该信号后便控制电池23向加热结构152供电，从而加热烟液，使烟液在加热作用下生成烟雾，实现了自动化控制。可以理解地，传感器23还可以是气流传感器。
本发明提供的烟弹10，密封件12可以被所述注液针头刺穿，以方便通过所述注液针头向储液腔110内注入烟液，并且在拔出所述注液针头后，密封件12上被刺穿位置能够自动恢复再次密封储液腔110，防止注液完毕后储液腔110内的烟液发生泄漏。另外，注液完毕后，第一盲孔121及第二盲孔122分别被第一电极13及第二电极14封堵，如此，即便储液腔110内的烟液经由刺穿位置泄漏，泄漏的烟液也能够被第一电极13和/或第二电极14密封，进一步防止了烟液泄漏。
本发明提供实施例一的电子烟，因其具有上述烟弹10全部的技术特征，故具有与上述烟弹10相同的技术效果。
实施例二
本发明的实施例二中，还公开了一种烟弹的注液方法，用于给电子烟的烟 弹进行注液。在一个具体的实施方式中，所述烟弹为实施例一中的烟弹10。烟弹10包括具有储液腔110的烟弹壳体11、用于密封储液腔110的密封件12，以及第一电极13和第二电极14，密封件12上远离储液腔110的端面上分别开设有用于安装第一电极13的第一盲孔121和用于安装第二电极14的第二盲孔122，密封件12由弹性材料制成，该注液方法包括：
步骤一：通过所述注液针头经由第一盲孔121及第二盲孔122中的至少一个的孔壁刺穿密封件12后与储液腔110连通以向储液腔110内注液；
步骤二：在完成注液之后，拔出所注液针头，密封件12在刺穿位置形成自密封；
步骤三：通过第一电极13封堵第一盲孔121，通过第二电极14封堵第二盲孔122。
另外，第二盲孔122的孔壁上开设有切口，注液过程中，储液腔110内的压力增加使得所述切口被顶开，储液腔110内的空气由所述切口排出。
本发明实施例二的烟弹的注液方法，在拔出所述注液针头后，密封件12上被刺穿位置能够自动恢复再次密封储液腔110，防止注液完毕后储液腔110内的烟液发生泄漏。另外，注液完毕后，第一盲孔121及第二盲孔122分别被第一电极13及第二电极14封堵，如此，即便储液腔110内的烟液经由刺穿位置泄漏，泄漏的烟液也能够被第一电极13和/或第二电极14密封，进一步防止了烟液泄漏。
以上述依据本发明的理想实施例为启示，通过上述的说明内容，相关的工作人员完全可以在不偏离本发明的范围内，进行多样的变更以及修改。本项发明的技术范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
