请一并参阅图1至图13，现对本实用新型实施例提供的雾化装置进行说明。本实用新型实施例提供的雾化装置适用于气溶胶发生装置，本实用新型实施例 提及的气溶胶发生装置一般包括雾化装置以及与雾化装置电性连接的电源装置。在使用气溶胶发生装置时，电源装置可向雾化装置提供电能，雾化装置在电驱动作用下加热并雾化存储在雾化装置内的气溶胶形成基质，由气溶胶形成基质雾化形成的气溶胶可供用户吸食。
请进一步结合参阅图1，本实用新型实施例提供的雾化装置包括雾化弹主体1和雾化芯2，雾化弹主体1的外廓呈柱状，雾化弹主体1的内部设有雾化腔或雾化通道3，雾化弹主体1的顶部设有与雾化腔或雾化通道3连通的抽吸口111。雾化芯2安装于雾化弹主体1上，雾化芯2可将气溶胶形成基质雾化形成气溶胶。雾化芯2可以是部分位于雾化腔或雾化通道3中，雾化芯2也可以是全部位于雾化腔或雾化通道3中，使得雾化芯2雾化形成的气溶胶可释放至雾化腔或雾化通道3中。雾化弹主体1上分别设有用于储存冷凝液的空腔4、与空腔4连通的进气通道51，以及用于扩散气流和引流冷凝液的均流孔道124，均流孔道124连通空腔4与雾化腔或雾化通道3，进气通道51的出气端口52所在平面的高度高于空腔4的内底面所在平面的高度，均流孔道124与进气通道51的出气端口52错开设置。则在用户通过抽吸口111抽吸气溶胶时，在抽吸形成的负压作用下，外部空气经由进气通道51引流至空腔4，引流至空腔4中的空气流经均流孔道124被扩散后，并经由均流孔道124均匀地引流至雾化腔或雾化通道3，使得空气与雾化腔或雾化通道3中的气溶胶充分混合，与空气混合后的气溶胶最终通过抽吸口111吸入用户口中。此外，由于均流孔道124与进气通道51的出气端口52错开设置，避免雾化腔或雾化通道3中的冷凝液流入进气通道51，使得雾化腔或雾化通道3中的冷凝液流只能经由均流孔道124引流至空腔4，加上进气通道51的出气端口52所在平面的高度高于空腔4的内底面所在平面的高度，使得引流至空腔4中的冷凝液储存于空腔4中，而不会流入进气通道51。因此，即使雾化腔或雾化通道3中的冷凝液产生聚集回流，聚集回流的冷凝液直接通过均流孔道124引流至空腔4，有效防止聚集回流的冷凝液通过进气通道51流出而造成污染，提升了用户的使用体验。
本实用新型实施例提供的雾化装置，与现有技术相比，通过在雾化弹主体1内部设置雾化腔或雾化通道3、用于储存冷凝液的空腔4、与空腔4连通的进气通道51，以及用于扩散气流和引流冷凝液的均流孔道124，均流孔道124连通空腔4与雾化腔或雾化通道3。在在雾化装置工作时，由进气通道51引入的空气，在流经均流孔道124时被均匀扩散，使得空气气流经由均流孔道124分散地引流至雾化腔或雾化通道3中，减少紊流或湍流的产生，有利于空气与气溶胶的充分混合。此外，由于进气通道51的出气端口52所在平面的高度高于空腔4的内底面所在平面的高度，均流孔道124与进气通道51的出气端口52错开设置，在雾化腔或雾化通道3中的冷凝液产生聚集回流时，聚集回流的冷凝液可直接通过均流孔道124引流至空腔4进行储存，有效防止聚集回流的冷凝液通过进气通道51流出而造成污染，提升了用户的使用体验。
请结合参阅图1和图7，在其中一些实施例中，空腔4位于雾化腔或雾化通道3的下方，均流孔道124位于雾化腔或雾化通道3的底部，使得雾化腔或雾化通道3中聚集回流的冷凝液，可快速地经由均流孔道124引流至空腔4中。
请结合参阅图1、图7和图8，在其中另一些实施例中，空腔4与雾化腔或雾化通道3之间隔设有均流件14，在均流件14上设有多个均流孔道124，多个均流孔道124等间隔地布置于均流件14上，在增强气流进入雾化腔或雾化通道3的均匀性的同时，还可降低聚集回流的冷凝液流经均流孔道124时对进气气流的阻碍作用。可以理解地，均流件14可以与雾化弹主体1的电极支架125一体成型。
请结合参阅图1和图7，在其中一些实施例中，各均流孔道124的中心轴线与进气通道51的中心轴线平行，各均流孔道124的中心轴线与进气通道51的中心轴线之间具有预设距离。请进一步结合参阅图14，作为一种实施方式，在均流孔道124和进气通道51的孔道截面均为圆形时，均流孔道124的中心轴线为A,进气通道51的中心轴线为B，均流孔道124的中心轴线为A与进气通道51的中心轴线为B相互平行，二者之间的预设距离大于或等于均流孔道124的 半径R1与进气通道51的半径R2之和。请进一步结合参阅图15，作为另一种实施方式，在均流孔道124和进气通道51的孔道截面均为具有长半轴和短半轴的椭圆形时，均流孔道124的长半轴为R3，均流孔道124的短半轴为R4，进气通道51的长半轴为R5，进气通道51的短半轴为R6,均流孔道124的中心轴线为C,进气通道51的中心轴线为D，均流孔道124的中心轴线为C与进气通道51的中心轴线为D相互平行，二者之间的预设距离大于或等于均流孔道124的长半轴R3与进气通道51的长半轴R5之和。这样，上述均流孔道124与进气通道51采取预设距离的分隔或错开设置，使得流经均流孔道124的冷凝液不会滴落在进气通道51的出气端口52中，从而有利于避免聚集回流的冷凝液通过进气通道51流出而造成污染。
在其中另一些实施例中，各均流孔道124的中心轴线与进气通道51的中心轴线平行，且均流孔道124与进气通道51的出气端口52在平面上的正投影不重叠，使得流经均流孔道124的冷凝液不会滴落在进气通道51的出气端口52中，从而有利于避免聚集回流的冷凝液通过进气通道51流出而造成污染。
请结合参阅图1、图7和图13，在其中一些实施例中，雾化弹主体1上设有进气管5，进气管5的管道构成进气通道51，进气通道51的第一端端口为进气通道51的进气端口53，进气通道51的第二端端口为进气通道51的出气端口52。可以理解地，在其中另一些实施例中，进气通道51可以与雾化弹主体1一体成型。
请结合参阅图1和图7，在其中一些实施例中，进气管5的第一端与雾化弹主体1相连，进气管5的第二端延伸至空腔4中，进气管5的第二端与空腔4的内顶面具有间距，可在空腔4的下部形成集液腔，并在空腔4的上部形成气流缓冲腔。这样，通过进气通道51引入空腔4的空气气流，可在气流缓冲腔中得到缓冲，发生流速降低，不仅有利于增强均流孔道124对空气气流的扩散效果，而且可避免过大的气压导致冷凝液无法通过均流孔道124引流至空腔4而造成飞液现象。
请结合参阅图1、图3和图13，在其中一些实施例中，为了便于用户抽吸气溶胶，雾化弹主体1上还设有用于供用户抽吸气溶胶的抽吸口111，雾化弹主体1上还设有连通雾化腔或雾化通道3与抽吸口111的出气通道131。可以理解地，在其中另一些实施例中，雾化弹主体1中还可以设有连通雾化腔或雾化通道3与抽吸口111的出气管13，出气管13的管道构成出气通道131。
请结合参阅图2、图3和图4，在其中一些实施例中，沿气流的流动方向，出气通道131的横截面积逐渐增大，使得流经出气通道131的气压逐渐变小，从而达到逐渐降低气流流速，一方面有利于出气通道131周壁上的冷凝液快速回流至雾化腔或雾化通道3，另一方面避免抽吸气流以较高的流速直接冲击用户的喉咙而造成不适。出气通道131在垂直于出气中心的任意位置的截面的投影为腰形、椭圆形、长方形，并腰形、椭圆形、长方形孔。腰形截面的出气通道131较圆形截面的出气通道131，在满足出气量的前提下，可以使出气通道131偏向一侧，有利于扩大雾化装置单侧下液的下液面积，同时能最大限度的提高气溶胶基质灌装量。出气通道131为从下至上的喇叭形扩口形状，更有利于出气通道131携带的气溶胶被用户抽吸，以提升用户体验感。
请结合参阅图1和图11，在其中一些实施例中，空腔4内设有用于吸附冷凝液的吸附件9，通过吸附件9对流入空腔4的冷凝液进行吸附，进一步增强了放漏液能力。可以理解地，吸附件9可以是但不限于具有良好吸液性能的吸液棉。
请结合参阅图1、图6和图7，在其中一些实施例中，雾化弹主体1包括顶部设有抽吸口111的储液件11、装配于储液件11底部的雾化座组件12和设于储液件11中的出气管13，雾化座组件12上分别设有空腔4、均流孔道124、进气通道51和雾化腔或雾化通道3，出气管13的第一端延伸至抽吸口111并与抽吸口111连通，出气管13的第二端延伸至雾化腔或雾化通道3的出气孔31，出气管13的第二端与出气孔31连通。储液件11内部于出气管13之外的部分界定出用于储存气溶胶形成基质的储液腔112，雾化座组件12上设有用于 安装雾化芯2的安装槽128和用于将储液腔112中的气溶胶形成基质传输至雾化芯2的输液通道129。请结合参阅图1、图8和图13，在其中一些实施例中，雾化座组件12包括装配于储液件11底端开口处的底座121、支撑于底座121上的雾化芯支架122和套设于雾化芯支架122上的密封套123，雾化芯支架122上分别设有空腔4、均流孔道124、进气通道51和雾化腔或雾化通道3。在其中另一些实施例中，雾化座组件12包括装配于储液件11底端开口处的底座121、支撑于底座121上的雾化芯支架122、装配于雾化芯支架122上的电极支架125和套设于雾化芯支架122上的密封套123，雾化芯支架122上分别设有均流孔道124、进气通道51和雾化腔或雾化通道3。请结合参阅图7、图9和图10，雾化芯支架122上设有第一收集槽126，电极支架125上设有第二收集槽127，第一收集槽126与第二收集槽127围合形成空腔4。在其中另一些实施例中，雾化座组件12包括装配于储液件11底端开口处的底座121、支撑于底座121上的雾化芯支架122、装配于雾化芯支架122上的电极支架125和套设于雾化芯支架122上的密封套123，雾化芯支架122上分别设有均流孔道124和雾化腔或雾化通道3，雾化芯支架122上设有第一收集槽126，进气通道51设于电极支架125上，电极支架125上设有第二收集槽127，第一收集槽126与第二收集槽127围合形成空腔4。可以理解地，请结合参阅图10和图13，上述实施例中，进气管5可与电极支架125一体成型。
请结合参阅图1、图11、图12和图13，在其中一些实施例中，雾化芯2可以是但不限于陶瓷雾化芯2，雾化弹主体1内部设有雾化通道3，雾化芯2设于雾化弹主体1上对应雾化通道3的位置。雾化芯2具有用于吸附并传输气溶胶的吸液面21和用于雾化并释放气溶胶的雾化面22。则在雾化装置工作时，储液腔112中的气溶胶形成基质可经由输液通道129传输至吸液面21，吸液面21上的气溶胶形成基质可经由雾化芯2的微孔传输至雾化面22，雾化芯2对传输至雾化面22的气溶胶进行加热雾化，雾化芯2雾化形成的气溶胶可经由雾化面22释放至雾化通道3。当用户在抽吸口111抽吸时，在用户抽吸负压的作用 下，外部空气经由进气通道51、空腔4、均流通道进入雾化通道3，雾化通道3内的气溶胶被空气气流输向出气通道131，直至经由抽吸口111被用户吸食。由于雾化通道3的中心轴线与雾化面22平行，使得流经雾化通道3的气流流向与雾化面22平行或近于平行，从而使得雾化通道3内的气流流向与雾化芯2内部气溶胶形成基质的流向垂直或近于垂直，可良好地克服雾化通道3的气流流向与雾化芯2内部气溶胶形成基质流向形成对冲的缺陷，避免对冲气流对雾化芯2的正常输液造成阻碍，有利于雾化芯2内部的气溶胶形成基质均匀分布，从而能够有效防止雾化芯2因供液不足或供液不充分而发生干烧碳化。
请结合参阅图1，在其中一些实施例中，由进气通道51、雾化通道3和出气通道131构成多段式气流通道，为了克服多段式气流通道存在偏折而引起多段式气流通道内气流冲击雾化面22、雾化通道3的壁面及出气通道131的壁面的情况发生，包括如下三种结构形式：
第一种结构形式是多段式气流通道的各段中心轴线在空间位置上可以共线，即进气通道51的中心轴线、雾化通道3的中心轴线及出气通道131的中心轴线三线共线。
第二种结构形式是在不影响多段式气流通道中的气流直接快速传输至出气口5的前提下，多段式气流通道的各段中心轴线中的至少一段中心轴线在空间位置上出现平行偏移，即包括：一是出气通道131的中心轴线、雾化通道3的中心轴线及进气通道51的中心轴线三线相互平行，二是出气通道131的中心轴线与雾化通道3的中心轴线相互平行，且进气通道51的中心轴线与出气通道131的中心轴线或雾化通道3的中心轴线共线，三是进气通道51的中心轴线与雾化通道3的中心轴线相互平行，且出气通道131的中心轴线与进气通道51的中心轴线或雾化通道3的中心轴线共线。

在其中一些实施例中，导电连接件6为金属片，金属片上具有配合抵触导电部7的接触面61，通过金属片的接触面61与导电部7呈面接触，接触更加可靠，同时其接触电阻更小。导电连接件6也可以为电极顶针，电极顶针的外周面上设有配合抵触导电部7的接触面61，通过电极顶针的接触面61与导电 部7呈面接触，接触更加可靠，同时其接触电阻更小。请进一步结合参阅图13，导电连接件6还可以为金属杆或金属棒，金属杆或金属棒的外周面上设有配合抵触导电部7的接触面61，通过金属杆或金属棒的接触面61与导电部7呈面接触，接触更加可靠，同时其接触电阻更小。
请进一步结合参阅图1、图11和图13，在其中一些实施例中，雾化装置还包括设于雾化芯支架122上的弹性件8，通过弹性件8将雾化芯2朝向导电连接件6抵顶，由于弹性件8发生弹性形变，从而使得导电连接件6受到回弹力作用，进而使得导电连接件6的外周面与导电部7相互抵触，保证了导电连接件6与雾化芯2上的导电部7接触的稳定性及可靠性。
请进一步结合参阅图1和图11，在其中一些实施例中，弹性件8上设有用于定位雾化芯2的定位槽81，雾化芯2容置于定位槽81中，在导电连接件6将雾化芯2朝向定位槽81中顶抵时，弹性件8发生弹性形变，从而使得导电连接件6与导电部7之间受到预紧力，将雾化芯2稳固地限定于定位槽81中，进一步增强导电连接件6与雾化芯2上的导电部7接触的稳定性及可靠性。
请进一步结合参阅图1和图8，在其中一些实施例中，雾化芯支架122上设有用于定位弹性件8的安装槽128，弹性件8装配于安装槽128中，可通过安装槽128将弹性件8限定于雾化芯支架122上，从而保证弹性件8装配于雾化芯支架122上的稳固性及可靠性。
