技术领域
本申请涉及电子雾化技术领域，尤其涉及一种气溶胶提供系统以及一种用于气溶胶提供系统的雾化器。
背景技术
气溶胶提供系统是一种将例如烟油、药液等的液体基质加热雾化成气雾以供吸食使用的电子产品。
气溶胶提供系统可包括雾化器和电源组件，所述电源组件用于为所述雾化器供电；所述雾化器可包括雾化芯组件和雾化仓，所述雾化芯组件用于在通电时发热而将液体基质雾化，所述雾化仓用于给所述雾化芯组件供应待加热雾化的液体基质。
气溶胶提供系统通常采用多孔陶瓷体作为吸取液体基质的毛细导液元件，并通过设置在多孔陶瓷体的雾化面上的加热元件来加热多孔陶瓷体内的至少部分液体基质生成气溶胶。
目前，烟油雾化技术多采用陶瓷发热。在一些方案中，陶瓷发热面设置成在上，也就是发热面朝向雾化设备的烟嘴。这使得电极引脚需要折弯一定角度，以便连接发热件的电极。然而，电极引脚的折弯角度以及弹力难以控制，使电极装配不方便，电极与陶瓷面接触的弹力也难以控制。另外，陶瓷芯需采用硅胶密封，以便密封装配在雾化座内。然而，这使得装配不便，且密封效果不好，可能存在漏液。同时，采用陶瓷芯发热的成本较高。再者，进气需要绕过陶瓷芯固定座的两侧壁进入，使得气流行程较大。

参阅图1所示，其为本申请一实施例提供的气溶胶提供系统100的立体组装示意图。该气溶胶提供系统100被配置为雾化液体基质以生成气溶胶，其可包括：存储有液体基质并对其进行汽化以生成气溶胶的雾化器100A；以及，为雾化器100A供应加热能量的电源组件100B。液体 基质例如可为烟油、药液等液体；本文中，液体基质亦可称为液体，汽化亦可称为雾化，气溶胶亦可称为烟气、气雾或雾化气。
结合图2、图3和图4所示，其为图1所示气溶胶提供系统100的两个截面示意图和图2中第I部分的放大示意图。如图所示，在一实施例中，所述气溶胶提供系统100可包括储液腔10A、感应发热体20、毛细元件30和电磁感应线圈60。所述储液腔10A为在所述气溶胶提供系统100内限定的容纳空间，用于存储液体基质，并向毛细元件30供应液体基质。所述电磁感应线圈60可由导线布置而成，用于在通电工作时产生可变化的磁场。所述感应发热体20可设置成位于电磁感应线圈60产生的变化磁场中，从而能够被变化的磁场穿透而发热，以加热液体基质。所述毛细元件30与所述感应发热体20接触设置，用于通过自身的毛细空间接收和存储来自所述储液腔10A的液体基质，并通过毛细作用将液体基质输送至所述感应发热体20附近；从而，随着感应发热体20发热时对靠近其的毛细元件30中的液体基质的消耗，毛细元件30可持续地朝着感应发热体20供应液体基质。所述毛细元件30定位在所述电磁感应线圈60与所述感应发热体20之间。例如，所述毛细元件30可由具有毛细通道或孔隙的材料制备，例如纤维棉、多孔陶瓷体、玻纤绳、多孔玻璃陶瓷、多孔玻璃等硬质或刚性毛细结构制成。所述毛细元件30与储液腔10A是流体连通的，以吸取自储液腔10A输送的液体基质。例如，可利用导油棉作为毛细元件30进行导油，导油棉自身会有一定的密封锁油能力，感应发热体20可放置在毛细元件30上面，使得雾化面积增大，雾化效果更好。
在此实施例的气溶胶提供系统100中，通过采用电磁感应线圈60产生可变化的磁场来对感应发热体20进行感应加热，从而无需设置用来与发热体导电连接的诸如电极引脚的导电结构，这使得气溶胶提供系统100中的包括感应发热体20和毛细元件30的雾化器装配容易、便捷，避免了对电极弹片的折弯和组装困难；而且，由于感应发热体20无需与导线连接，其可设置成相较于毛细元件30更远离电磁感应线圈60，从而方便将毛细元件30的发热面定向成朝向或靠近气溶胶提供系统100的排烟管13，进而雾化所产生的气溶胶无需绕经毛细元件30，而是直接进入排烟管13内，并被用户抽吸。
结合图5和图6所示，其分别为图1所示气溶胶提供系统100的立体分解示意图，以及气溶胶提供系统100的感应发热体20的立体示意图。如图所示，在一可选实施例中，所述感应发热体20为扁平式延伸的带孔加热片。例如，所述感应发热体20整体可呈平板形，其沿厚度 方向开设多个通孔21，从而可使雾化产生的气溶胶穿过这些通孔21朝远离毛细元件30的方向发散而出。所述感应发热体20可通过在片状材料中开孔制成，亦可采用具有网孔的发热网结构。
结合图7所示，其为气溶胶提供系统100的电磁感应线圈60的立体示意图。如图7所示，在一可选实施例中，所述电磁感应线圈60为平面延伸的线圈。电磁感应线圈60可弯折形成大致方形的结构，并且整体呈平板形状。另外，电磁感应线圈60的两端可连接导线引脚61，以与电源组件100B中的电池80导电连接。通过将所述电磁感应线圈60设置为平面延伸的形状，可便于对电磁感应线圈60的放置和定位。
在一可选实施例中，结合图2至图4所示，所述气溶胶提供系统100包括气流通道，并且所述气流通道的一部分引导气流绕过所述毛细元件30或是穿过所述毛细元件30并到达所述感应发热体20上方的雾化空间45A。例如，气流通道整体上可始于气溶胶提供系统100的进气端72，并止于气溶胶提供系统100的出气端18。进气端72可为开设在电池壳70上的通孔。出气端18可位于壳体组件10的吸嘴部14。气流通道可设置成使得在气流经进气端72进入气溶胶提供系统100后，通过位于毛细元件30旁边的通道传输，再经过高于毛细元件30的通道传输到所述感应发热体20上方的雾化空间45A。或者是，气流通道可设置成使得在气流经进气端72进入气溶胶提供系统100后，由位于毛细元件30内的通道传输到所述感应发热体20上方的雾化空间45A；这能够缩短气流行程。以此方式，气流进入雾化空间45A后，可将在雾化空间45A内雾化产生的气溶胶携带出该出气端18。
在一可选实施例中，结合图2至图4所示，所述毛细元件30定位相较于所述感应发热体20更加远离所述储液腔10A。例如，可通过壳体组件10限定所述储液腔10A，并且将毛细元件30设置在壳体组件10的底部位置，将感应发热体20设置在毛细元件30靠近储液腔10A的一侧。以此方式，仍然便于将毛细元件30的发热面定向成朝向或靠近气溶胶提供系统100的排烟管13，进而雾化所产生的气溶胶无需绕经毛细元件30，而是直接进入排烟管13内。
在一可选实施例中，结合图2至图4所示，所述感应发热体20叠置在所述毛细元件30的上表面，并且通过支架40按压固定在所述毛细元件30上。例如，所述感应发热体20和毛细元件30均可设置成平板形状，从而能够将感应发热体20叠置在所述毛细元件30的上表面。支架40可安装在气溶胶提供系统100内，同时将感应发热体20按压固定在所述毛细元件30上，达到对感应发热体20和毛细元件30的固定效 果。感应发热体20不用完全覆盖毛细元件30的上表面，从而使得毛细元件30表面裸露的部分可以释放气溶胶。以此方式，也使得感应发热体20和毛细元件30的装配较为简单。
在一可选实施例中，结合图2、图3和图5所示，所述气溶胶提供系统100的雾化器100A包括所述感应发热体20和毛细元件30，并且还可包括壳体组件10。所述壳体组件10限定所述储液腔10A，并且包括吸嘴部14、底端部15和排烟管13。所述底端部15与所述吸嘴部14相背设置，所述排烟管13自所述吸嘴部14在所述壳体组件10内部朝向所述底端部15延伸。所述毛细元件30位于所述壳体组件10内并设置在所述底端部15上，所述感应发热体20定位成相较于所述毛细元件30更靠近所述排烟管13。以此方式，雾化所产生的气溶胶可直接进入排烟管13内。

在一可选实施例中，结合图2至图4所示，所述感应发热体20通过支架40按压固定在所述毛细元件30上。所述支架40位于所述壳体组件10内，并限定有连通所述储液腔10A以将液体基质引导至所述毛细元件30的第一通道44以及连通所述排烟管13的第二通道45，所述第二通道45的至少一部分作为所述感应发热体20上方的雾化空间45A。以此方式，既可实现由支架40对感应发热体20和所述毛细元件30的按压固定，又可通过支架40提供用于液体和气体连通的第一通道44和第二通道45。另外，毛细元件30的端部可位于第一通道44的下方，从而能够吸收第一通道44中的液体基质。
在一可选实施例中，结合图3和图5所示，所述支架40包括弹性按压件41和用于支撑所述弹性按压件41的支撑部件42。所述弹性按压件41用于将所述感应发热体20按压固定在所述毛细元件30表面上。此外，所述支架40还可包括第一密封件43。所述第一密封件43连接在 所述支撑部件42的上端，所述弹性按压件41连接在所述支撑部件42的下端。
例如，如图8和图9所示，其分别为弹性按压件41的两个立体示意图，弹性按压件41的顶端可包括卡槽41B，用于与支撑部件42卡紧配合；弹性按压件41的底端可包括抵压面41C以及从抵压面41C向下延伸的定位柱41D。所述弹性按压件41可通过抵压面41C将所述感应发热体20按压固定在所述毛细元件30上。例如，所述弹性按压件41可为硅胶制成。
另外，如图10所示，为毛细元件30的立体示意图，毛细元件30两端可开设定位孔31；从而，弹性按压件41的定位柱41D可插入毛细元件30的定位孔31中，实现对毛细元件30的安装定位。
例如，如图11和图12所示，其分别为支撑部件42的两个立体示意图，支撑部件42可由硬质材料制成，以提供结构支撑，其下端可包括插板42A，用于与弹性按压件41的卡槽41B配合；其上端可包括环形壁42B，用于供第一密封件43套设其上。支撑部件42的侧壁上还可设有卡块42C，用于与壳体组件10卡扣配合。

在一可选实施例中，结合图2、图3、图5和图15所示，其中图15为图5所示气溶胶提供系统100的底座12的立体示意图。所述壳体组件10的底端部15设有进气孔16，所述进气孔16纵向延伸使其端口高于所述毛细元件30的上表面。所述支架40设有缺口41A，使得所述进气孔16输出的气流经所述缺口41A到达所述感应发热体20上方的雾化空间45A。例如，所述壳体组件10可包括上壳体11和底座12，所述底座12包括所述底端部15。所述进气孔16可设置在所述壳体组件10的底座12上，所述进气孔16的上端开口设置成高于所述毛细元件30，并且可进一步高于感应发热体20。所述缺口41A可开设在所述支架40的弹性按压件41上。另外，所述底座12的侧壁上可开设卡槽12A，用于 与支撑部件42侧壁上的卡块42C卡扣配合。由于无需开设导线或电极片的通道，因此底座12可直接开设形成收容毛细元件30的上开口容纳槽，从而可防止漏液。
另外，如图15所示，所述底座12的外侧面上还可形成有多个漏液储存槽12C。这些漏液储存槽12C可自底座12的外侧面凹入设置，亦可通过设置在底座12的外侧面上的多个凸条限定而成。通过形成这些漏液储存槽12C，泄漏到底座12的外侧面上的液体可被这些漏液储存槽12C例如借助毛细作用而吸收、储存，进而可限制这些泄漏的液体的流动。结合图5所示，所述底座12的外侧面上还可形成环形凹槽12D，环形凹槽12D内可嵌设密封圈50，以和上壳体11形成密封。
在一可选实施例中，结合图2、图3、图4、图5和图16所示，其中图16为图5所示气溶胶提供系统100的上壳体11的立体示意图。上壳体11大致被构造成中空的筒状，并具有位于近端的吸嘴部14；其具有位于远端的敞口，进而通过敞口便于在上壳体11内部装配各功能部件。所述远端的横截面可为跑道形或者椭圆形等接近扁平的形状。所述储液腔10A主要由上壳体11限定，排烟管13自所述吸嘴部14在所述壳体组件10内部朝向所述远端延伸。上壳体11在靠近远端处的外侧可设有卡块11A。
在一可选实施例中，结合图3、图4、图5、图16和图17所示，其中图17为图5所示气溶胶提供系统100的底部罩19的立体示意图。底部罩19可为金属制成，其可在侧壁上开设卡孔19A，以与上壳体11的卡块11A卡扣配合，进而将底座12保持与上壳体11结合。
在一可选实施例中，结合图1和图2所示，所述气溶胶提供系统100包括电源组件100B。所述电源组件100B包括电池壳70、电池80和所述电磁感应线圈60，所述电池壳70收容所述电池80和所述电磁感应线圈60，所述电磁感应线圈60与所述电池80电连接。电磁感应线圈60例如可位于所述电池80的上方。电池80用于向电磁感应线圈60提供电流，以使电磁感应线圈60产生可变化的磁场。电磁感应线圈60应尽量靠近雾化器100A中的感应发热体20设置，使得感应发热体20位于电磁感应线圈60产生的电磁场中。
在一可选实施例中，结合图3所示，所述电磁感应线圈60与所述感应发热体20平行设置。通过将所述感应发热体20和所述电磁感应线圈60设置为平面延伸的形状，可使得他们能够平行设置，并且便于对感应发热体20和电磁感应线圈60的放置和定位。
在其他一些实施例中，电磁感应线圈60可改用其他结构和布置方 式。例如，可将电磁感应线圈构造成一个立体形式的柱形螺旋线圈，并且将其布置电源组件100B的收容腔的圆周方向，烟弹插入收容腔时正好使感应发热体20被此柱形螺旋线圈环绕，进而能够处在磁场空间中。
在一可选实施例中，结合图2和图5所示，所述电池壳70还限定插入腔71，所述雾化器100A的一部分可插设在所述插入腔71内。
进一步地，为了保证感应加热效率，将烟弹形式的雾化器100A放入到插入腔71中时扁平式的感应发热体20与平面延伸的电磁感应线圈60的距离应该尽可能小，同时考虑中间的毛细元件30需要具有一定的储油量和锁油能力，毛细元件30不能做得太薄。例如，感应发热体20与电磁感应线圈60的有效距离可在2至4mm之间，以能够保证具有较高的发热效率，优选是3mm左右，而毛细元件30的厚度可控制在1至1.5mm之间。
在一可选实施例中，结合图2、图3、图4和图18所示，其中图18为图5所示气溶胶提供系统100的绝缘件91的立体示意图。绝缘件91设置在电池壳70内，用于盖住电磁感应线圈60。绝缘件91的顶端可形成凹部91A，凹部91A可作为气溶胶提供系统100内气流通道的一部分。凹部91A两侧与凹槽91B连通，凹槽91B则与开设在电池壳70上的进气端72对应和连通。绝缘件91的侧壁还可设置卡槽91C和环形凹槽91D。环形凹槽91D内可嵌设密封圈94，以和电池壳70形成密封，进而阻止由雾化器100A渗流至插入腔71的液体基质流向电源组件100B内部的控制器95、传感器96等部件。传感器96可用于感测雾化器100A的进行抽吸时产生的抽吸气流，进而控制器95根据该传感器96的检测信号控制电池80向电磁感应线圈60输出电流。
在一可选实施例中，结合图2、图3和图19所示，其中图19为气溶胶提供系统100的线圈支架92的立体示意图。线圈支架92的顶端可形成收容槽92A，用于在其内放置电磁感应线圈60。再如图2所示，电源组件100B还可包括安装支架93，安装支架93可收容固持电池80，并且可通过卡扣与绝缘件91的卡槽91C卡扣配合，进而将线圈支架92和电磁感应线圈60保持在安装支架93上。
参阅图20和图21所示，其分别为本申请另一实施例提供的气溶胶提供系统100的截面示意图和局部放大示意图。该实施例的气溶胶提供系统100与前述气溶胶提供系统大致相同，同样包括雾化器100A和电源组件100B；雾化器100A又包括壳体组件10、感应发热体20、毛细元件30和支架40；电源组件100B又包括电磁感应线圈60、电池壳70和电池(图未示，可参见图2中的电池80)。
该实施例的气溶胶提供系统100与前述气溶胶提供系统的不同之处在于：在图20所示实施例的气溶胶提供系统100中，所述壳体组件10的底端部15包括延伸穿过所述毛细元件30的进气柱17，所述进气柱17的末端高于所述毛细元件30的上表面。进气柱17的内部是中空的，以提供竖直的导气通道17A。通过如此设置进气柱17，气流可直接向上输送并进入感应发热体20上方的雾化空间45A，从而可减短气流行程。进气柱17末端的端面高于毛细元件30的雾化面，从而可防止烟液漏出。
在一些实施例中，进气柱17的数量可为一或多个，例如可为两个。进气柱17的轴线和壳体组件10的排烟管13的轴线可设置成错开，以免排烟管13中的冷凝液向下落在进气柱17上，造成堵塞。
在一些其他实施例中，进气柱17的端面可设计为封闭，进气柱17的侧部则可开设有径向的出气孔来连通竖直的导气通道17A。出气孔设置成不被例如导油棉的毛细元件30和例如发热片的感应发热体20所覆盖，且可贴近感应发热体20的表面。
在一些其他实施例中，支架40可限定连通所述排烟管13的第二通道45，其中第二通道45靠近进气柱17的内表面可具有将气流从雾化空间45A两侧向中心排烟管13引导的斜面。
在一些实施例中，结合图20、图22和图23所示，其中图22和图23分别为图20所示气溶胶提供系统100的支架40的两个立体示意图；支架40可包括抵压面41C。从而，所述感应发热体20可通过支架40的抵压面41C按压固定在所述毛细元件30上。所述支架40为第二密封件；例如，所述支架40可为硅胶制成，以具有支撑和密封性能。
所述壳体组件10包括上壳体11和底座12。结合图24和图25所示，其分别为图20所示气溶胶提供系统100的底座12的两个立体示意图。所述底座12包括所述底端部15。作为第二密封件的支架40安装在所述底座12上；所述底座12可插设在所述上壳体11的下端开口处。作为第二密封件的支架40的至少一部分构造成在所述底座12和所述上壳体11之间提供密封。其中，所述第二密封件通过侧壁40A与所述底座12的侧壁12B围成第三通道46，所述第三通道46连通储液腔10A以将液体基质引导至所述毛细元件30，所述第二密封件还包括所述第二通道45，所述第二通道45的至少一部分构造成所述感应发热体20上方的雾化空间45A。通过采用一体成型的支架40，可减少部件数量，进而方便组装。另外，所述底座12的侧壁上还可设有卡块12E，用于与上壳体11卡扣配合。
结合图26所示，其为图20所示气溶胶提供系统100的电磁感应线 圈60的立体示意图。如图所示，在一可选实施例中，所述电磁感应线圈60为平面延伸的螺旋线圈。电磁感应线圈60可缠绕或螺旋形成大致圆形或椭圆形的结构，并且整体呈平板形状。另外，电磁感应线圈60的两端可连接导线引脚61，以与电源组件100B中的电池导电连接。通过将所述电磁感应线圈60设置为平面延伸的形状，可便于对电磁感应线圈60的放置和定位。
以上介绍了本申请的气溶胶提供系统100及其雾化器100A的各种部件。在需要使用气溶胶提供系统100进行抽吸时，可先打开电源组件100B的电源开关，以便由电池80为电磁感应线圈60供电；然后，当用户对雾化器100A的吸嘴部14进行吸气时，即可通过气溶胶提供系统100的控制器95依据吸气动作而启动电源组件100B和雾化器100A进行工作，最终产生供用户吸食的气雾。其中，来自储液腔10A的液体基质被感应发热体20加热雾化形成气雾，外部空气可依次流经所述进气端72、凹槽91B、凹部91A、进气孔16与缺口41A(或者是导气通道17A)，从而输送至毛细元件30的雾化面上方，再将所形成的气溶胶经第二通道45携带出排烟管13。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；在本申请的思路下，以上实施例或者不同实施例中的技术特征之间也可以进行组合，步骤可以以任意顺序实现，并存在如上所述的本申请的不同方面的许多其它变化，为了简明，它们没有在细节中提供；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
