以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、技术之类的具体细节，以便透彻理解本发明实施例。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施例中也可以实现本发明。在其它情况中，省略对众所周知的系统、装置、电路以及方法的详细说明，以免不必要的细节妨碍本发明的描述。
图1-图14示出了本发明第一实施例中的电子雾化装置，该电子雾化装置可用于雾化液态基质以生成气溶胶，该气溶胶可供用户吸食或者吸入，其在本实施例中可大致呈圆柱状。可以理解地，在其他实施例中，该电子雾化装置也可呈椭圆柱状、扁平柱状或方形柱状等其他形状。该液态基质可以包括烟油或药液等。
该电子雾化装置可包括外壳10以及收容于外壳10中的控制模块20、电源30、气源40、储液雾化组件60和加热组件80。控制模块20分别与气源40、加热组件80电连接，用于接收指令，该指令可由用户触发或者在电子雾化装置满足一定条件后自动触发，控制模块20根据该指令控制气源40、加热组件80的工作。电源30分别与控制模块20、气源40、加热组件80电连接，用于向控制模块20、气源40、加热组件80提供电能。储液雾化组件60包括用于存储液态基质的储液腔610以及与该储液腔610相连通的喷嘴620。气源40与喷嘴620相连通，用于为喷嘴620提供定量的高压空气，例如，可以通过轴流泵实现提供高速气流，也可以通过释放压缩气体实现提供高速气流。该高速气流可辅助喷嘴62将来自储液腔610的液态基质雾化成细小的液体颗粒。喷嘴620喷出的液体颗粒群撞击加热组件80，经过加热组件80加热后生成气溶胶由气流带出以供用户吸食或者吸入。
在一些实施例中，也可以通过其他的方式将液态基质雾化成细小的液体颗粒群，如高压喷嘴等，在此不作限制。将细小的液体颗粒群再通过加热组件80进一步的加热雾化。
本发明通过将液态基质雾化成液体颗粒群后再由加热组件80蒸发的方式，由于雾化后形成的细小液体颗粒群的表面积得到了极大的扩展，从而更容易加热蒸发，一方面可提高热量及气溶胶的转化效率，另一方面可降低加热组件80蒸发过程的温度，实现低温雾化。在较低的加热雾化温度下，液态基质主要物理变化过程，从而克服了传统的多孔陶瓷或者多孔棉条件下因必须采用高温方式雾化而导致的液态基质热裂解变质的问题，更不会发生烧焦、积碳和重金属挥发等现象，从而能够保持不同液态基质所特有的成分和香精香料体系，最终使吸入者感受到与原始液态基质相对应的特有的口感。此外，加热组件80与储液腔610不接触，加热组件80不用长期浸泡在液态基质中，减少了加热组件80对液态基质的污染，从而减少了雾化后生成的气溶胶中的杂质气体。
在一些实施例中，外壳10可包括下壳12以及沿纵向配合于下壳12上端的上壳11。具体地，在本实施例中，下壳12可呈两端开口的圆筒状，该外壳10还包括沿纵向封盖于下壳12下端开口处的底座13。可以理解地，在其他实施例中，该底座13也可与下壳12一体成型。进一步地，该电子雾化装置还可包括沿纵向设置于上壳11中的通气管70，通气管70的内壁面界定出与喷嘴620相连通的出气通道71。加热组件80可收容于通气管70中，加热组件80、通气管70、外壳10均可同轴设置。
进一步地，下壳12中可设置有支架组件14，该支架组件14将下壳12内分隔成位于上部的第一收容空间121以及位于下部的第二收容空间122。控制模块20、电源30、气源40均可收容于该第二收容空间122中。其中，该控制模块20可包括电路板以及形成于该电路板上的控制电路，该电源30可包括电池，该气源40可包括气泵。储液雾化组件60可收容于第一收容空间121中并可支撑于支架组件14上。进一步地，该电子雾化装置还可包括气流感应元件50，该气流感应元件50可安装于支架组件14的底部。气流感应元件50控制模块20电连接，用于感应用户抽吸时的气流变化并传递信号至控制模块20。控制模块20在检测到用户有抽吸动作时，发送信号至气源40以启动气源40开始供气，并发送信号至加热组件80以启动加热组件80开始加热。在一些实施例中，气流感应元件50可与为负压传感器，例如咪头。
在一些实施例中，外壳10还可包括设置于上壳11顶部的吸嘴15，用户可通过吸嘴15吸食气溶胶。该吸嘴15呈中空管状，其内壁面界定出与出气通道71相连通的用于输出气溶胶的吸气通道150。吸嘴15的下端可嵌置于通气管70中，吸嘴15的下端外壁面与通气管70的上端内壁面密封配合。在本实施例中，吸嘴15与上壳11分别成型后再组装在一起；在其他实施例中，吸嘴15与上壳11也可一体成型。
进一步地，在一些实施例中，该电子雾化装置还可包括可拆卸地罩设于上壳11外的防尘罩90。在不需要使用电子雾化装置时，可将防尘罩90罩设于上壳11外，防止灰尘等杂质进入吸气通道150。
如图2、图3所示，该储液雾化组件60可包括储液壳61以及至少部分收容于储液壳61的喷雾组件62。在本实施例中，储液壳61内设空腔以作为储液腔610。喷雾组件62包括喷嘴620，喷嘴620具有喷雾口621，可以喷出第一平均粒径雾气；需要说明的是，在一些实施例中，第一平均粒径雾气可以理解为上述的液体颗粒群。
如图2、图4-图14所示，加热组件80收容于通气管70中并位于喷嘴620的上方，且与喷嘴620的喷雾口621相对设置；优选与喷嘴620同轴设置。加热组件80可采用电阻传导加热、红外辐射加热、电磁感应加热或者复合加热等方式进行加热。加热组件80的结构可包括金属发热体（例如发热片、发热网或发热丝），或者也可包括多孔介质以及设置于多孔介质上的发热体（例如发热膜、发热片、发热网或发热丝）。在本实施例中，加热组件80包括至少一个发热体81，该发热体81在通电后发热，能够对从喷雾口621喷出的第一平均粒径雾气加热雾化为小于第一平均粒径的第二平均粒径，即将上述的液体颗粒群雾化为气溶胶。
在一些实施例中，加热组件80包括至少两个发热体81。其中，相邻两个发热体81之间平行间隔排布，任意相邻两个发热体81之间的间距优选相同。在另一些实施例中，相邻的两个发热体81之间对称排布或者交错排布设置。
每个发热体81包括呈网状的发热线路811，发热线路811与喷雾口621相对设置。该发热线路811能够完全接收由喷雾口621喷射过来的液体颗粒群，液体颗粒群在受热雾化后形成气溶胶，通过发热线路811上的网孔812流向吸气通道150，最终被用户吸食。
进一步地，发热线路811在一些实施例中为平面结构；在另一些实施例中，发热线路811为折弯的平面结构；在再一些实施中，发热线路811呈弧面结构，比如球面型。
进一步地，发热线路811包括发热主干8110以及设于发热主干8110上的多个网孔812。在一些实施例中，为了使得雾化效果更加均匀，该些网孔812呈规律排布。可选地，网孔812的形状包括多边形、梯形、圆形、椭圆形或它们中至少一种的组合。
进一步地，发热主干8110包括至少一个发热主部8111；具体地，发热主部8111包括按照预设规律连接的多个发热单元；在本实施例中，预设规律是沿同一直线依次连接，该直线方向为发热线路811的长度方向L。位于始末端的发热单元还各自与对应的第一电极连接部814和第二电极连接部815连接。可选地，多个发热单元的壁厚均相同。
在一些实施例中，发热单元呈空心的闭合图形结构，其空心部分形成第一镂空单元8121。闭合的图形，可以是多边形、梯形、圆形或者椭圆形。在一些实施例中，第一镂空单元8121的形状与发热单元的形状相同。
在一些实施例中，每个发热单元可由金属材料制成，比如铁、铜。
在一些实施例中，发热主干8110包括至少两个发热主部8111、以及连接于相邻发热主部8111之间的连接部8112。相邻的两个发热主部8111位于同一平面，平行且间隔排布，它们两个之间通过连接部8112连接。可以理解地，该连接部8112除了用于作为相邻的两个发热主部8111之间的连接部8112件外，也具有导电发热的功能。在本实施例中，在同一个发热主干8110的相邻两个发热主部8111中，相应的连接部8112设于相对的两个发热单元之间距离最短的位置。更进一步地，相邻的两个连接部8112，与该两个连接部8112相邻的四个发热单元围设形成第二镂空单元8122。第二镂空单元8122的形状可与第一镂空单元8121的形状相同或者不相同；在一些实施例中，通过调整连接部8112的轴向长度，可使得第一镂空单元8121与第二镂空单元8122的形状相同。
可以理解地，网孔812包括上述第一镂空单元8121、第二镂空单元8122。在一些实施例中，网孔812还包括第三镂空单元8123。具体地，第三镂空单元8123是由连接部8112、与其相邻的两个发热单元，以及对应的第一电极连接部814或第二电极连接部815围设成形的。
在一些实施例中，发热体81还包括与发热线路811连接第一电极连接部814和第二电极连接部815，该第一电极连接部814和第二电极连接部815分别与电源30的两极电性连接，在本实施例中，第一电极连接部814和第二电极连接部815均呈片状结构，分别位于发热线路811的两端，优选在发热线路811长度方向L的两端。发热线路811中所有发热主部8111并联连接于第一电极连接部814和第二电极连接部815之间。
在一些实施例中，发热体81还包括与发热线路811中发热主干8110连接的多个散热部813；该散热部813可将发热线路811上热量较高位置的热量通过散热件分散开，使得发热机构整体热量较为平衡。在一些实施例中，多个散热部813在发热线路811长度方向L两侧分别向外延伸成型。在本实施例中，在发热线路811最外侧的发热主部8111中，多个发热单元分别沿其最外侧的壁面向外延伸，相应形成多个散热部813。可选地，散热部813为杆状、条状或板状，其形状为直线、曲线或它们中至少一种的组合。
在一些实施例中，散热部813与多个发热单元的壁厚均相同。
在一些实施例中，加热组件80还包括导液体82。该导液体82为多孔介质，用于将穿过网状的发热线路811的未能捕获的液体颗粒群给吸收掉，防止液体颗粒直接通过发热体81，减少第一平均粒径的液体颗粒与气溶胶混合的几率；同时，被导液体82吸收的液体可再次被发热线路811所加热雾化。具体地，导液体82设置于至少一个发热体81与喷雾口621相背的表面，且覆盖至少一个发热体81的至少部分网孔812。优选导液体82覆盖至少一个网状发热体81的全部网孔812。在一些实施例中，导液体82紧贴于发热体81与喷雾口621相背的表面设置。另外，导液体82可包括多孔体；可选地，多孔体包括导液棉或者多孔陶瓷。
具体地，该导液体82设置于至少一个发热体81与喷雾口621相背的表面，且覆盖至少一个发热体81的至少部分网孔812。优选导液体82覆盖至少一个网状发热体81的全部网孔812。
可以理解地，导液体82为多孔介质，导液体82设有多个具有毛细作用力的毛细孔，具备一定的吸液能力，能够将穿过网状的发热线路811的未能捕获的液体颗粒群给吸收掉，防止液体颗粒直接通过发热体81，减少第一平均粒径的液体颗粒与气溶胶混合的几率。同时，在毛细力的作用下，多孔介质能够保持湿润，发热线路811可将多孔介质表面的液体雾化形成气溶胶，气溶胶穿过发热线路811上的网孔812和多孔介质的毛细孔流向吸气通道150，最终被用户吸食。
为了更进一步说明本发明，以下列举几个具体实施例进行详细说明：
在实施例1-1，如图2、图8所示，加热组件80包括至少一个发热件，该发热件的发热线路811呈蜂窝状的平面结构，也可看作mesh网结构；多个网孔812的形状大致相同，均呈六边形。在发热线路811的长度方向L两端分别连接第一电极连接部814、第二电极连接部815；同时，在发热线路811的长度方向L两侧还设有均匀分布的多条散热部813。在该实施例中，喷嘴620的轴向垂直于发热线路811的平面。
可以理解地，该发热线路811可接收由喷雾口621喷射过来的液体颗粒群，液体颗粒群在受热雾化后形成气溶胶，通过发热线路811上的网孔812流向吸气通道150，进而被用户吸食。同时，由于网孔812的设计，液滴不容易积聚于加热组件80表面，使得加热组件80的表面难以形成液膜，从而减少发热体表面形成液膜的厚度，提高雾化效率；除此之外，还抑制炸液的发生，确保用户的食用口感。
在该实施例中，可通过调整网孔812的大小，以达到减少液体颗粒积聚的作用。可以理解地，通过调整网孔812的面积大小，能够有效控制液体颗粒群的通过率、雾化速率，以及发热线路811的发热效率。譬如，当需要减小液体颗粒群的通过率时，可以减小网孔812的面积；当需要增加液体颗粒群的雾化速率或者发热线路811的发热效率，可以增加网孔812的面积，从而减小发热线路811中发热单元的占有比，以提高热流密度。
在实施例1-2，如图4、图9所示，与实施例中1-1的加热组件80的结构大致相同，区别在于，加热组件80在实施例1-2中包括平行、间隔且交错排布的至少两个发热体81，使得各自的网孔812交错布置。具体地，在相邻的两个发热体81中，该两者之其一发热体81的多个发热单元各自的部分投影，落于该两者之另一发热体81的对应网孔812位置中。
可以理解地，实施例中1-1的加热组件80虽然可以对液体颗粒群进行加热雾化，但是部分液体颗粒群会直接从网孔812中穿过，使得该部分液体颗粒群的加热效果未达到最佳。因此，在实施例1-2，可通过设置交错排布的两个发热体81，穿过第一个发热体81的部分液体颗粒群，可以被第二个发热体81捕获，进行第二次加热雾化，从而使得所有液体颗粒群均得到更好的加热雾化效果。当然，加热组件80还可包括更多个发热体81，其中任意相邻的两个发热体81之间交错排布，使得该两者各自的网孔812交错布置。在通过第一个发热体81的液体颗粒群将被第二个发热体81捕获，通过第二个发热体81的液体颗粒群又将被第三个发热体81捕获，依此类推。
在一些实施例中，相邻两个发热体81中，后一发热体81的发热单元与前一发热体81的网孔812相对设置。需要说明的是，前一发热体81是指相邻两个发热体81中相对邻近雾化口621的一发热体81，而后一发热体81是指相邻两个发热体81中相对远离雾化口621的另一发热体81。通过调整相邻两个发热体81中对应发热单元与网孔812的相对位置，可提高发热单元捕获液体颗粒群的几率。在另一些实施例中，如图9所示，相邻两个发热体81之间在长度方向L上交错排布，该两者之间的错位距离为X，错位距离X大于0mm，且小于网孔812在长度方向L的长度值。在该实施例中，通过调整网孔812的面积大小，能够有效控制液体颗粒群通过其中一个发热线路811的通过率、雾化速率，以及发热线路811的发热效率。譬如，当需要减小液体颗粒群通过其中一个发热线路811的通过率时，可以减小网孔812的面积；当需要增加液体颗粒群的雾化速率或者发热线路811的发热效率，可以增加网孔812的面积，从而减小发热线路811中发热单元的占有比，以提高热流密度。
此外，在加热组件80包括至少两个发热体81的实施例中，从喷嘴62喷出的第一平均粒径雾气依次经过多个发热体81的过程中，第一平均粒径雾气会加热雾化为第二平均粒径雾气，该第一平均粒径雾气的体积会逐渐减小，实际上发热体81越远离喷雾口621的，其所能捕获的液体颗粒的数量越小。因此，为了节省功耗以及避免电子雾化装置的工作温度过高，在加热组件80包括至少两个发热体81时，发热体81的发热功率是随着与喷雾口621之间的距离增大而逐渐变小。
在实施例1-3，与实施例中1-1的加热组件80的结构大致相同，区别在于，如图10、图11所示，加热组件80中发热件的发热线路811呈球面网状结构。具体地，发热线路811沿喷嘴620轴向方向凹陷，形成平滑的球面；使得，发热线路811具有与喷雾口621相对设置的凹面，和与喷雾口621相背设置的凸面。
可以理解地，在发热线路811呈平面时，由喷雾口621喷出的液体颗粒群会因为leindenfrost效应而在发热线路811上产生回弹，导致雾化量衰减。而若将发热线路811改为曲面结构，在液体颗粒群撞击发热线路811时，各个液体颗粒可以从首次抵接凹面上的其中一个点弹到另一个点；举例说明，定义其中一液体颗粒为第一液体颗粒6111，如图11所示，可以看到第一液体颗粒6111随着箭头指示方向依次接触凹面上的两个点。由此可见，在该实施例中，可使得液滴颗粒可获得与发热线路811的发热面接触的二次机会，得到被二次加热的机会，从而减少液体颗粒回弹的几率，抑制液体颗粒回弹现象及提高雾化量。通过调整发热线路811的曲率，可以改变液体颗粒群中各个颗粒的运动轨迹。
在实施例1-4，与实施例中1-1的加热组件80的结构大致相同，区别在于，如图12、图13所示，该发热体81呈折弯后的平面结构，其中，发热件的折点位于其发热线路811上，使得发热线路811形成非平面结构。具体地，发热线路811具有至少一个折弯部816，使得位于对应折弯部816两侧的发热主体部分呈夹角α设置；优选地，夹角α的范围区间为[60，120]，单位为°；更优选的是，夹角α的范围区间为[60，90]，单位为°。
可以理解地，在发热线路811呈平面时，由喷雾口621喷出的液体颗粒群会因为leindenfrost效应而在发热线路811上产生回弹，导致雾化量衰减。通过设置折弯的网状发热线路811，可改变液体颗粒群撞击发热线路811时的弹射角度，使液体颗粒能够再次被发热线路811的发热面所捕获，增加液体颗粒与发热线路811的发热面的换热量，提高换热效率。同时，通过调整夹角α，可调整液体颗粒群撞击发热线路811时的弹射角度，增加液体颗粒与发热线路811的发热面的换热量，提高液体颗粒被发热线路811的发热面所捕获的几率，以及提高雾化量和雾化效率。
其次，经喷雾口621喷出的液体颗粒群分布并非是均匀的，一般存在特定的分布规律，如正态分布。若采用相关技术中的发热体81，无法根据液体颗粒群分布的规律来调整温度分布，导致雾化效率降低。在该实施例中，可通过改变折弯部816在发热线路811上的位置和/或增加折弯部816的数量，改变发热线路811的温度分布。可以理解地，相对于发热线路811其他位置，位于折弯处的电流密度会增加，发热线路811的发热面的表面温度会相对增加，根据液体颗粒群分布的规律，可调整折弯部816在发热线路811上的位置和/或增加折弯部816的数量，进而改变发热线路811的温度分布，使液体颗粒群的全体均可得到对应最优的加热效果。
在实施例1-5，与实施例中1-1的加热组件80的结构大致相同，区别在于，如图14所示，加热组件80除了包括发热体81，还包括导液体82；具体地，该导液体82紧贴于发热体81与喷雾口621相背的表面设置，且其长度、宽度分别略大于该发热体81的发热线路811对应长度和宽度，使得导液体82完全覆盖该发热体81的所有网孔812。
可以理解地，导液体82为多孔介质，导液体82设有多个具有毛细作用力的毛细孔，具备一定的吸液能力，能够将穿过网状的发热线路811的未能捕获的液体颗粒群给吸收掉，防止液体颗粒直接通过发热体81，减少第一平均粒径的液体颗粒与气溶胶混合的几率。同时，在毛细力的作用下，多孔介质能够保持湿润，发热线路811可将多孔介质表面的液体雾化形成气溶胶，气溶胶穿过发热线路811上的网孔812和多孔介质的毛细孔流向吸气通道150，最终被用户吸食。
其中，多孔介质的毛细孔的孔径可根据吸液能力的需求，和发热线路811的发热效率和液体颗粒群的雾化速率所进行调整。
可以理解地，上述的实施例之间的技术特征可根据实际需要而相互混合使用，以获得相对最优的技术方案。
综上，本发明通过设置包含有呈网状发热线路的发热体，可减少发热体表面形成液膜的厚度，提高雾化效率；还可抑制雾气在撞击发热体时的回弹，减少雾气的损失，提高雾化量；此外，还可以抑制炸液的发生，减少粒径大的液滴产生，确保用户的食用口感。
可以理解的，以上实施例仅表达了本发明的优选实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制；应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，可以对上述技术特点进行自由组合，还可以做出若干变形和改进，这些都属于本发明的保护范围；因此，凡跟本发明权利要求范围所做的等同变换与修饰，均应属于本发明权利要求的涵盖范围。
