具体实施方式
下面结合附图和实施例，对本申请作进一步的详细描述。
请参阅图1a和图1b，图1a是本申请提供的电子雾化装置的结构示意图,图1b是本申请提供的电子雾化装置的方框示意图。
电子雾化装置包括启动通道1、气流传感器2和吸嘴部3。启动通道1一端通至吸嘴部3，一端通至气流传感器2，启动通道1靠近气流传感器2的一段设置有吸液部21，吸液部21用于通过毛细作用力吸引流经启动通道1的液体。启动通道1连通吸嘴部3和气流传感器2，抽吸时产生负压，气流传感器2感应到气压变化而启动加热功能，从而电子雾化装置开始工作。
电子雾化装置还包括储液仓4、雾化通道5、进气口6和电源7。雾化通道5连通进气口6和吸嘴部3，且雾化通道5与启动通道1连通。雾化通道5包括雾化腔51，雾化芯52设置在雾化腔51内，雾化芯52用于雾化来自储液仓4的液体，吸液部21设置在雾化芯52与气流传感器2之间。电源7用于给雾化芯52供电，以使雾化芯52工作雾化液体。
雾化通道5包括出气通道53，出气通道53贯穿储液仓4，出气通道53的一端与吸嘴部3连通，另一端与雾化腔51连通；进气口6与雾化腔51连通。抽吸时产生负压，外界空气从进气口6进入雾化腔51的同时气流传感器2感应到气压变化而启动加热功能，外界空气带着雾化芯52雾化好的液体经出气通道53到达吸嘴部3，被用户吸食。
其中，部分启动通道1与雾化腔51和出气通道53共用。
请参阅图2，是本申请提供的电子雾化装置的启动通道1第一实施例的结构示意图。
启动通道1包括第一段气道11、第二段气道12和吸液元件容置腔13；第一段气道11的一端通至气流传感器2，第一段气道11的另一端连通第二段气道12的一端，第二段气道12的另一端通至吸嘴部 3；第一段气道11与第二段气道12的延伸方向垂直。吸液元件容置腔13与第一段气道11连通。其中，第一段气道11通至气流传感器2的一端同时连通外界。
由于启动通道1与雾化通道5的流体相通，雾化通道5的雾化气冷凝后的冷凝液会进入启动通道1。电子雾化装置漏液后，漏液也会进入启动通道1。进入启动通道1的漏液和冷凝液会污染气流传感器2，且影响启动通道1的通畅。
第一段气道11用于连通外界的一端的侧壁上设置有通孔111，用作与气流传感器2相连通的接口。通孔111的形状尺寸不限，可以根据气流传感器2的尺寸进行设计。通常选用咪头作为气流传感器2，也可以选用其他元件作为气流传感器2，能够实现启动电子雾化装置的功能即可，本申请对此不做限定。
第一实施例中，吸液元件容置腔13内设置有吸液部21，吸液部21包括多孔储液元件211。多孔储液元件211设置于吸液元件容置腔13的整个空间。多孔储液元件211为储液棉或多孔陶瓷。液体沿着从靠近第二段气道12到远离第二段气道12的方向在多孔储液元件211中扩散。在使用过程中，多孔储液元件211吸满液体或吸液速度变慢后可以更换多孔储液元件211，能够尽可能的避免液体滞留在启动通道1内，进而避免液体浸泡气流传感器2，提升电子雾化装置的性能。
可以理解，多孔储液元件211可以填充部分或填满整个吸液元件容置腔13；甚至在多孔储液元件211填满整个吸液元件容置腔13后，部分第一段气道11内也设置有多孔储液元件211，使多孔储液元件211具有最大限度的吸液能力。当吸液部21包括吸液后膨胀的材料时，该材料仅填充部分吸液元件容置腔13。
可以理解，第一段气道11与第二段气道12的延伸方向也可以不垂直，只要具有一定夹角可以满足需要即可。第二段气道12为密闭的管状结构。第一段气道11也为管状结构，但第一段气道11与吸液元件容置腔13连接的侧壁上具有开口，从而使得吸液元件容置腔13与第一段气道11连通。
请参阅图3，是本申请提供的电子雾化装置的启动通道1第二实施例的结构示意图。
第二实施例中，吸液部21包括毛细引流结构212。毛细引流结构212包括多个第一肋片2121，多个第一肋片2121之间间隔平行设 置形成第一毛细槽2122；即，第一毛细槽2122的数量为多个，第一毛细槽2122之间并排设置。可以理解，毛细引流结构212至少包括两个第一肋片2121，即形成至少一个第一毛细槽2122。第一毛细槽2122用于吸引并储存流经启动通道1的液体，保持启动通道1的通畅，避免液体浸泡气流传感器2。
多个第一肋片2121的宽度为0.6-1.0mm，第一毛细槽2122的宽度为0.3-0.5mm。其中，多个第一肋片2121的延伸方向与第一段气道11的延伸方向的夹角大于30度，优选为60-90度，使得液体可以顺畅的通过第一毛细槽2122吸引。本实施例中，多个第一肋片2121的延伸方向与第一段气道11的延伸方向的夹角为90度。
在本实施例中，多个第一肋片2121靠近第一段气道11的一端距第一段气道11的中心轴线的距离相等且为0.9-1.5mm。多个第一肋片2121远离第一段气道11的一端距第一段气道11的中心轴线的距离可以相等，也可以不相等。
在其他实施方式中，吸液元件容置腔13包括与第一段气道11对应的第一区域221以及与第二段气道12对应的第二区域222；设置在第一区域221内的第一肋片2121靠近第一段气道11的一端与第一段气道11的中心轴线的距离为第一距离L1，设置在第二区域222内的第一肋片2121靠近第一气道11的一端与第一段气道11的中心轴线的距离为第二距离L2，第一距离L1大于第二距离L2。
具体地，设置在第二区域222内的多个第一肋片2121的多个第二距离L2可以相等且为0.3-0.5mm；设置在第一区域221内的多个第一肋片2121的第一距离L1相等且为0.9-1.5mm。
另一实施方式，设置在第二区域222内的多个第一肋片2121的多个第二距离L2可以不相等，且沿着从远离第一区域221到靠近第一区域221的方向形成等差递减，等差为0.3-0.5mm；设置在第一区域221内的多个第一肋片2121的多个第一距离L1相等且为0.9-1.5mm。
请参阅图4，是本申请提供的电子雾化装置的启动通道1第三实施例的结构示意图。
本申请第三实施例的启动组件与本申请第二实施例的电子雾化装置的结构基本相同，其区别在于，吸液部21包括多孔储液元件211和毛细引流结构212。毛细引流结构212包括多个第一肋片2121。具体地，吸液元件容置腔13包括靠近第一段气道11的第一空间22和 远离第一段气道12的第二空间23。多个第一肋片2121设置在第一空间22内。多孔储液元件211设置在第二空间23内，即多个第一肋片2121设置在多孔储液元件211与第一段气道11之间。多个第一肋片2121之间间隔平行设置形成第一毛细槽2122。多个第一肋片2121的宽度为0.6-1.0mm，第一毛细槽2122的宽度为0.3-0.5mm。其中，多个第一肋片2121的延伸方向与第一段气道11的延伸方向的夹角大于30度，优选为60-90度，使得液体可以顺畅的通过第一毛细槽2122流入第二空间23。本实施例中，多个第一肋片2121的延伸方向与第一段气道11的延伸方向的夹角为90度。
在本实施例中，多个第一肋片2121靠近第一段气道11的一端距第一段气道11的中心轴线的距离相等且为0.9-1.5mm。多个第一肋片2121远离第一段气道11的一端距第一段气道11的中心轴线的距离可以相等，也可以不相等；只需满足多个第一肋片2121远离第一段气道11的一端与多孔储液元件211接触即可。
第一毛细槽2122连通第一段气道11和第二空间23，以使进入启动通道1内的液体可以通过第一毛细槽2122流入第二空间23内，被第二空间23内的多孔储液元件211吸收，保持启动通道1的通畅，避免液体浸泡气流传感器2。液体沿着从靠近第二段气道12到远离第二段气道12的方向在多孔储液元件211上扩散。
通过在吸液元件容置腔13内设置多个第一肋片2121，对流入启动通道1的液体进行导流，使液体被多孔储液元件211吸收。当漏液量较少，流入启动通道1的液体通过多个第一肋片2121之间的第一毛细槽2122的导流被多孔储液元件211吸收，不影响启动通道1的通畅性。当漏液量较大，流入启动通道1的液体先被多个第一肋片2121导流至多孔储液元件211，多孔储液元件211不具有吸液能力时，再进一步使第二段气道12内的液面抬升，使连通气流传感器2的通孔111为液体最后接触到的区域，最大限度的保护气流传感器2。在使用过程中，多孔储液元件211吸满液体或吸液速度变慢后更换多孔储液元件211，能够尽可能的避免液体滞留在启动通道1内，进而避免液体浸泡气流传感器2，提升电子雾化装置的性能。
请参阅图5，是本申请提供的电子雾化装置的启动通道1第三实施例的实验现象图。
由图5可知，通过设置多个第一肋片2121和多孔储液元件211，能够对液体进行导流，使得漏液进入启动通道1的液体被多孔储液元 件211吸收，最大限度的保护气流传感器2，防止液体滞留在启动通道1内。但第一毛细槽2122中下部液体上升与上部液体下沉会形成气柱。实验中，实验件的开口侧壁面与亚克力板贴合，便于观察液体流动。
请参阅图6，是本申请提供的电子雾化装置的启动通道1第四实施例的结构示意图。
本申请第四实施例的启动组件与本申请第三实施例的电子雾化装置结构基本相同，其区别在于，多个第一肋片2121的结构不同。具体地，第四实施例中，吸液部21包括多孔储液元件211和多个第一肋片2121。吸液元件容置腔13包括靠近第一段气道11的第一空间22和远离第一段气道12的第二空间23。多个第一肋片2121设置在第一空间22内。多孔储液元件211设置在第二空间23内。多个第一肋片2121之间间隔平行设置形成第一毛细槽2122。多个第一肋片2121的宽度为0.6-1.0mm，第一毛细槽2122的宽度为0.3-0.5mm。
第一毛细槽2122连通第一段气道11和第二空间23，以使进入启动通道1内的液体可以通过第一毛细槽2122流入第二空间23内，被第二空间23内的多孔储液元件211吸收，保持启动通道1的通畅，避免液体浸泡气流传感器2。
在本实施例中，吸液元件容置腔13包括与第一段气道11对应的第一区域221以及与第二段气道12对应的第二区域222；定义设置在第一区域221内的第一肋片2121靠近第一段气道11的一端与第一段气道11的中心轴线的距离为第一距离L1，设置在第二区域222内的第一肋片2121靠近第一段气道11的一端与第一段气道11的中心轴线的距离为第二距离L2，第一距离L1大于第二距离L2，即，设置在第二区域222内的第一肋片2121的高度大于设置在第一区域221内的第一肋片2121的高度。
具体实施方式中，设置在第二区域222内的多个第一肋片2121的多个第二距离L2相等且为0.3-0.5mm；设置在第一区域221内的多个第一肋片2121的多个第一距离L1相等且为0.9-1.5mm。多个第一肋片2121远离第一段气道11的一端距第一段气道11的中心轴线的距离可以相等，也可以不相等；只需满足多个第一肋片2121远离第一段气道11的一端与多孔储液元件211接触即可。
请参阅图7，是本申请提供的电子雾化装置的启动通道1第四实施例的另一实施方式结构示意图。
在另一实施方式中，设置在第二区域222内的多个第一肋片2121的多个第二距离L2沿着从远离第一区域221到靠近第一区域221的方向形成等差递减，等差为0.3-0.5mm；设置在第一区域221内的多个第一肋片2121的多个第一距离L1相等且为0.9-1.5mm。多个第一肋片2121远离第一段气道11的一端距第一段气道11的中心轴线的距离可以相等，也可以不相等；只需满足多个第一肋片2121远离第一段气道11的一端与多孔储液元件211接触即可。
请参阅图8，是本申请提供的电子雾化装置的启动通道1第四实施例的另一实施方式的实验现象图。
由图8可知，第二区域222内的多个第一肋片2121的多个第二距离L2沿着从远离第一区域221到靠近第一区域221的方向形成等差递减，多孔储液元件211占吸液元件容置腔13体积的1/2，能够兼顾促进下液和加大储液量，最大限度的保护气流传感器2以及保持启动通道1畅通。实验中，实验件的开口侧壁面与亚克力板贴合，便于观察液体流动。
其中，多个第一肋片2121的延伸方向与第一段气道11的延伸方向的夹角为60-90度，使得液体可以顺畅的通过第一毛细槽2122流入第二空间23。优选，多个第一肋片2121的延伸方向与第一段气道11的延伸方向的夹角为90度。
通过在吸液元件容置腔13内设置多个第一肋片2121，对流入启动通道1的液体进行导流，使液体被多孔储液元件211吸收。把吸液元件容置腔13分为与第一段气道11对应的第一区域221，和与第二段气道12对应的第二区域222，通过将第一距离L1设置为大于第二距离L2，使得通过第二段气道12与雾化通道5连通的接口进入启动通道1的液体更加顺畅的进入第一毛细槽2122。为了避免第二区域222中的多个第一肋片2121之间形成毛细作用，影响液体进入第一区域221中的多个第一肋片2121形成的第一毛细槽2122，可以将设置在第二区域222内的多个第一肋片2121的多个第二距离L2沿着从远离第一区域221到靠近第一区域221的方向形成等差递减。液体沿着从远离第一区域221到靠近第一区域221的方向在多孔储液元件211上扩散。
当漏液量较少，流入启动通道1的液体通过多个第一肋片2121的导流被多孔储液元件211吸收，不影响启动通道1的通畅性。当漏液量较大，流入启动通道1的液体先被多个第一肋片2121导流至多 孔储液元件211，多孔储液元件211不具有吸液能力时，再进一步使第二段气道12内的液面抬升，使连通气流传感器2的通孔111为液体最后接触到的区域，最大限度的保护气流传感器2。在使用过程中，多孔储液元件211吸满液体或吸液速度变慢后更换多孔储液元件211，能够尽可能的避免液体滞留在启动通道1内，进而避免液体浸泡气流传感器2，提升电子雾化装置的性能。
第三实施例和第四实施例中，第二空间23至少占吸液元件容置腔13体积的1/2；在其他实施方式中，第二空间23占吸液元件容置腔13体积的1/3。在吸液元件容置腔13内设置的多孔储液元件211越多，吸液、储液能力越大。将第二空间23设置为至少占吸液元件容置腔13体积的1/2，能够兼顾促进下液和加大储液量，最大限度的保护气流传感器2以及保持启动通道1畅通。

在本次实验中，多个第一肋片2121和多个第二肋片2123一一对应设置，多个第一肋片2121与多个第二肋片2123之间形成第三毛细槽2125，能够避免第一毛细槽2122或第二毛细槽2124中形成气柱。通过设置多个第一肋片2121、多个第二肋片2123和多孔储液元件211，保护气流传感器2以及保持启动通道1畅通。实验中，实验件的开口侧壁面与亚克力板贴合，便于观察液体流动。
在其他实施方式中，吸液元件容置腔13包括与第一段气道11对应的第一区域221以及与第二段气道12对应的第二区域222；设置在第一区域221内的第一肋片2121靠近第一段气道11的一端与第一段气道11的中心轴线的距离为第一距离L1，设置在第二区域222内的第一肋片2121靠近第一气道11的一端与第一段气道11的中心轴线的距离为第二距离L2，第一距离L1大于第二距离L2。

本次实验中，设置在第二区域222内的多个第一肋片2121的多个第二距离L2相等，设置在第一区域221内的多个第一肋片2121 的多个第一距离L1相等，使得第一区域221和第二区域222之间的第一肋片形成梯度，使得液体可以更加顺畅的进入第一区域221中的第一毛细槽2122和第二毛细槽2124。通过设置多个第一肋片2121、多个第二肋片2123和多孔储液元件211，保护气流传感器2以及保持启动通道1畅通。实验中，实验件的开口侧壁面与亚克力板贴合，便于观察液体流动。
请参阅图14，是本申请提供的电子雾化装置的启动通道1第五实施例的另一实施方式的结构示意图。图14中，设置在第二区域222内的多个第一肋片2121的多个第二距离L2可以不相等，且沿着从远离第一区域221到靠近第一区域221的方向形成等差递减，等差为0.3-0.5mm；设置在第一区域221内的多个第一肋片2121的多个第一距离L1相等且为0.9-1.5mm。
请参阅图15，是图14提供的电子雾化装置的启动通道1的实验现象图。
本实验中，设置在第二区域222内的多个第一肋片2121的多个第二距离L2沿着从远离第一区域221到靠近第一区域221的方向形成等差递减，能够避免第二区域222中的多个第一肋片2121之间形成毛细作用，影响液体进入第一区域221中的多个第一肋片2121形成的第一毛细槽2122和第二毛细槽2124。实验中，实验件的开口侧壁面与亚克力板贴合，便于观察液体流动。
第五实施例中，多个第一肋片2121和多个第二肋片2123一一对应设置。多个第一肋片2121和多个第二肋片2123的延伸方向与第一段气道11的延伸方向的夹角为60-90度，使得液体可以顺畅的通过第一毛细槽2122和第二毛细槽2124流入第二空间23。优选，多个第一肋片2121和多个第二肋片2123的延伸方向与第一段气道11的延伸方向的夹角为90度。
通过在吸液元件容置腔13内设置多个第一肋片2121和多个第二肋片2123，对流入启动通道1的液体进行导流，使液体被多孔储液元件211吸收。把吸液元件容置腔13分为与第一段气道11对应的第一区域221，和与第二段气道12对应的第二区域222，通过将第一距离L1设置为大于第二距离L2，使得通过第二段气道12与雾化通道5连通的接口进入启动通道1的液体更加顺畅的进入第一毛细槽2122和第二毛细槽2124。为了避免第二区域222中的多个第一肋片2121之间形成毛细作用，影响液体进入第一区域221中的多个第一肋片 2121形成的第一毛细槽2122和第二毛细槽2124，可以将设置在第二区域222内的多个第一肋片2121的多个第二距离L2沿着从远离第一区域221到靠近第一区域221的方向形成等差递减。通过多个第一肋片2121与多个第二肋片2122之间形成第三毛细槽2125，避免液体在第一毛细槽2122或第二毛细槽2124形成气柱，影响液体被多孔储液元件211吸收。液体沿着从远离第一区域221到靠近第一区域221的方向在多孔储液元件211上扩散。
当漏液量较少，流入启动通道1的液体通过多个第一肋片2121和多个第二肋片2123的导流被多孔储液元件211吸收，不影响启动通道1的通畅性。当漏液量较大，流入启动通道1的液体先被多个第一肋片2121和多个第二肋片2123导流至多孔储液元件211，多孔储液元件211不具有吸液能力时，再进一步使第二段气道12内的液面抬升，使连通气流传感器2的通孔111为液体最后接触到的区域，最大限度的保护气流传感器2。在使用过程中，多孔储液元件211吸满液体或吸液速度变慢后更换多孔储液元件211，能够尽可能的避免液体滞留在启动通道1内，进而避免液体浸泡气流传感器2，提升电子雾化装置的性能。
在第二实施例、第三实施例、第四实施例、第五实施例中，远离气流传感器2的毛细槽的毛细作用力比靠近气流传感器2的毛细槽的毛细作用力大，这样可以使漏液更多的储存在远离气流传感器2的地方。毛细引流结构212可以包括多个第一肋片2121和/或多个第二肋片2123，多个第一肋片2121和多个第二肋片2123的材料为金属或陶瓷。当毛细引流结构212包括多孔陶瓷，多孔储液元件211为多孔陶瓷，毛细引流结构212的毛细作用力与多孔储液元件211的毛细作用力不同。
