具体实施方式
为了便于理解本申请，下面结合附图和具体实施方式，对本申请进行更详细的说明。
请参阅图1、图3及图4，本申请提出一种电子烟100，其包括装置壳体1、雾化组件2、电池组件3及气流感应器a，所述雾化组件2、电池组件3及气流感应器a均插设在所述装置壳体1内。所述雾化组件2内设置有雾化装置23，所述装置壳体1上开设有进气孔11并且在该装置壳体1内形成有邻接所述雾化装置23的烟雾通道b，所述烟雾通道b用于供雾化烟油形成的烟雾从所述电子烟100内排出。在所述进气孔11与所述烟雾通道b之间形成有供外界空气流至该烟雾通道b内的气流路径，所述气流感应器a与该气流路径相连通。所述气流感应器a用于感应用户的吸烟动作，以控制电子烟100雾化烟油。
所述气流路径至少包括第一气流通道c及第二气流通道d，所述第一气流通道c自所述进气孔11向所述气流感应器a的方向延伸并与所述气流感应器a连通，用于引导所述电子烟100外的气体朝所述气流感应器a的方向流动，吸烟时进入第一气流通道c的外部气流朝所述气流感应器a的方向流动。所述第二气流通道d用于连通所述第一气流通道c与所述烟雾通道b，以将所述第一气流通道c流过来的气体朝背向所述气流感应器a的方向引导至所述烟雾通道b。
在本实施例中，第一气流通道c及第二气流通道d位于气流感应器a的同一侧，并且第一气流通道c及第二气流通道d沿电子烟100的径向至少部分是重叠的。所述第二气流通道d的第一端与所述第一气流通道c及所述气流感应器a相连通，所述第二气流通道d的第二端与所述烟雾通道b相连通，用户吸烟时，进入第一气流通道c的外部气流先朝所述气流感应器a的方向流动，然后再转向流入所述第二气流通道d，朝背向所述气流感应器a的方向流动，以引导至所述烟雾通道b。由于所述第二气流通道d的第一端与所述第一气流通道c及所述气流感应器a相连通，因而在气流从第一气流通道c流入第二气流通道d时，则可快速促使所述气流感应器a的周围形成负压，以触发所述气流感应器a。其中，气流流动的方向如图4箭头所示。
在本申请优选的实施例中，所述电子烟100内还设置有储油槽e，所述储油槽e位于所述烟雾通道b的轴心线上并与所述烟雾通道b相连通，用于存 储泄漏的烟油。所述气流路径还包括第三气流通道f，所述第三气流通道f的第一端与所述第二气流通道d相连通，所述第三气流通道f的第二端与所述储油槽e相连通，所述第二气流通道d通过所述第三气流通道f及所述储油槽e与所述烟雾通道b相连通，因此，所述烟雾通道b泄漏的烟油可收集在所述储油槽e内，较好地避免烟油四处泄漏。
所述第三气流通道f沿所述电子烟100的横向方向延伸设置，所述烟雾通道b沿所述电子烟100的纵向方向延伸设置，因而泄漏的烟油不容易通过所述第三气流通道f流入所述第二气流通道d内，较好地避免用户吸食到烟油及避免烟油堵塞第三气流通道f。所述第一气流通道c及第二气流通道d均沿着所述电子烟100的纵向方向延伸设置，因而在吸烟时，在所述气流感应器a的周围尽可能产生较大负压，从而可提高灵敏度。
请参阅图2至图6，在本实施例中，所述雾化组件2包括均设置在所述装置壳体1内的储油体21、雾化座22、所述雾化装置23及吸油件24，所述储油体21内设置有储油腔g及所述烟雾通道b，所述雾化座22与所述储油体21相连。本实施例的所述电子烟100为不可拆卸的一体结构，所述雾化组件2与电池组件3同轴设置。可以理解的是，在某些实施例中，所述雾化组件2与所述电池组件3可拆卸连接，所述装置壳体1分为第一装置壳体和第二装置壳体，所述第一装置壳体套设在所述雾化组件2上，所述第二装置壳体套设在所述电池组件3上。
所述雾化装置23插设在所述烟雾通道b内，用于雾化所述储油腔g内的烟油。所述吸油件24位于所述雾化装置的下方，用于吸附泄漏的烟油，更具体地，所述吸油件24位于所述雾化座22与所述雾化装置23之间。通过设置所述吸油件24对泄漏的烟油进行吸附，因而，可进一步降低烟油四处泄漏的概率。具体地，所述储油体21包括储油套211、通气管212及密封圈213，所述通气管212插设在所述储油套211内，所述通气管212与所述储油套211之间形成所述储油腔g，所述通气管212内形成所述烟雾通道b。
所述通气管212的侧壁设置油导油孔215，通过所述导油孔215将所述储油腔g内的烟油导入所述雾化装置23。所述密封圈213套设在所述通气管212的外周面处并与所述储油套211的内壁面相抵接，因而可提高烟油的密封性能。可以理解的是，所述储油体21可以由一个或者多个储油部件形成，其结 构在此不做具体限定，只要能够存储烟油即可。
所述雾化座22与所述储油体21的端部相连，用于支撑所述储油体21，所述雾化座22的外壁与所述装置壳体1的内壁之间形成所述第一气流通道c。所述雾化座22背向所述储油体21的一端设置有所述第二气流通道d，所述第二气流通道d在所述雾化座22内朝向雾化座22的另一端延伸，从而与储油体21内的烟雾通道b相连通。因此，其具有结构简单，便于生产制造的优点。具体地，所述雾化座22包括板体部221，所述板体部221面向所述电池组件3的表面朝所述电池组件3所在的方向延伸形成有柱体部222及第一环体部223，所述第一环体部223环绕所述柱体部222设置，所述第一环体部223与所述装置壳体1之间形成有所述第一气流通道c，所述第一环体部223与所述柱体部222之间形成有所述第二气流通道d。此种结构不仅便于制造，而且所述第一气流通道c及所述第二气流通道d不容易堵塞。较佳地，所述柱体部222的长度大于所述第一环体部223的长度，即所述第一气流通道c及所述第二气流通道d的长度都小于所述柱体部222的长度，所述第一气流通道c与所述第二气流通道d的连接处位于所述柱体部222一端外周面处，因而，气路较通畅。
所述板体部221背向所述电池组件3的表面设置有所述储油槽e，所述储油槽e延伸至所述柱体部222内，即通过所述柱体部222进行存储泄漏的烟油，所述储油槽e的槽口面向所述烟雾通道b设置，所述储油槽e与所述烟雾通道b同轴设置，因而极大地降低了泄漏的烟油四处流动的概率。所述吸油件24位于所述储油槽e的槽口处。所述吸油件24设置有与所述槽口位置相对应的通气孔241，所述通气孔241与所述储油槽e及所述烟雾通道b相连通，因而所述吸油件24能够较好地吸附泄漏的烟油。所述储油槽e的槽壁处设置有与所述第二气流通道d及储油槽e相连通的所述第三气流通道f。所述板体部221背向所述电池组件3的表面朝背向所述电池组件3的方向延伸形成有第二环体部224，所述第二环体部224与所述储油体21相连。
所述雾化装置23插设在所述储油体21内，用于雾化所述储油腔g内的烟油。具体地，所述雾化装置23及所述吸油件24均插设在所述通气管212内，所述雾化装置23包括多孔陶瓷管231、电热丝232及导油管233，所述多孔陶瓷管231面向所述电池组件3的端面与所述吸油件24相接触，因而可 阻碍所述多孔陶瓷管231的烟油泄漏至所述电池组件3。所述电热丝232插设在所述多孔陶瓷管231内，所述导油管233套设在所述多孔陶瓷管231上，用于吸附所述储油腔g内的烟油。所述导油管233可以由无纺布或者棉等缠绕形成，其材料不做具体限定，只要能够吸附烟油以给所述多孔陶瓷管231供油即可。可以理解的是，在某些实施例中，可以无需设置所述导油管233。在某些实施例中，可以通过在所述多孔陶瓷管231内印刷导电发热层，以替换所述电热丝232。因此，所述雾化装置23的结构在此不做具体限定，只要能够雾化烟油即可。
所述电子烟100还包括吸嘴盖组件4，所述吸嘴盖组件4盖设在所述装置壳体1的一端并与所述储油体21扣接相连，所述吸嘴盖组件4设置有与所述烟雾通道b相连通的排烟孔40。由于所述吸嘴盖组件4与所述储油体21扣接相连，因而可较好地避免所述吸嘴盖组件4脱落，避免儿童误食所述吸嘴盖组件4。
所述吸嘴盖组件4包括盖体41、连接管42及密封套43，所述储油体21背向所述电池组件3的端面处设置有连接槽216，具体地，所述连接槽216位于所述储油套211的端面处，所述连接槽216的内壁面处设置有环形的第一卡扣217。所述盖体41盖设在所述装置壳体1的一端，所述连接管42的第一端插设在所述盖体41内，所述连接管42的第二端插设在所述密封套43内，所述连接管42的外周面处设置有与所述第一卡扣217扣接相连的第二卡扣421，所述密封套43的端面及外周面均与所述连接槽216弹性抵接，所述排烟孔40贯穿所述密封套43的端面以与所述烟雾通道b相连通，因而连接可靠，且较好避免烟油泄漏至用户口腔。
所述电池组件3与所述雾化组件2电连接，用于为所述雾化组件2供电，其包括电池31、固定座32及所述气流感应器a，所述电池31插设在所述装置壳体1内并与所述气流感应器a电连接，所述气流感应器a插设在所述固定座32内并与所述雾化组件2电连接。所述气流感应器a与所述固定座32之间形成有与所述电子烟100的外表面相连通的气仓33，所述气流感应器a与所述装置壳体1之间形成有与所述第二气流通道d相连通的负压仓34，可以理解的是，所述装置壳体1的一端端部由所述固定座32密封。用户吸烟时，所述负压仓34内的气体朝所述第二气流通道d流动，因而形成负压，从而触 发所述气流感应器a。所述气仓33与所述负压仓34相互隔离以阻碍气仓33内的气体流入所述负压仓34内，因而可提高所述电子烟100的灵敏度。
综上所述，由于所述第一气流通道c自所述进气孔11向所述气流感应器a的方向延伸并与所述气流感应器a连通，用于引导所述电子烟100外的气体朝所述气流感应器a的方向流动；所述第二气流通道d用于连通所述第一气流通道c与所述烟雾通道b，以将所述第一气流通道c流过来的气体朝背向所述气流感应器a的方向引导至所述烟雾通道。即通过所述第一气流通道c与所述第二气流通道d的配合，在吸烟时，先将气体引导朝气流感应器a所在的方向流动，然后再通过所述第二气流通道d引导气体背向所述气流感应器a运动，以增加所述气流感应器a所在区域的负压，因而可提高电子烟100的灵敏度。
需要说明的是，本申请的说明书及其附图中给出了本申请的较佳的实施例，但并不限于本说明书所描述的实施例，进一步地，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本申请所附权利要求的保护范围。
