请参阅图1，图1是本申请一实施例提供的电子雾化装置的结构示意图。在本实施例中，提供一种电子雾化装置100。该电子雾化装置100可用于气溶胶生成基质的雾化。电子雾化装置100包括相互电连接的雾化器1和主机2。
其中，雾化器1用于存储气溶胶生成基质并雾化气溶胶生成基质以形成可供用户吸食的气溶胶。该雾化器1具体可用于不同的领域，比如，医疗、美容、休闲吸食等。在一具体实施例中，该雾化器1可用于电子气溶胶化装置，用于雾化气溶胶生成基质并产生气溶胶，以供抽吸者抽吸，以下实施例均以此休闲吸食为例；当然，在其他实施例中，该雾化器1也可应用于喷发胶设备，以雾化用于头发定型的喷发胶；或者应用于治疗上下呼吸系统疾病的设备，以雾化医用药品。
雾化器1的具体结构与功能可参见以下实施例所涉及的雾化器1的具体结构与功能，且可实现相同或相似的技术效果，在此不再赘述。
主机2包括电池(图未示)和控制器(图未示)。电池用于为雾化器1的工作提供能量，以使得雾化器1能够雾化气溶胶生成基质形成气溶胶；控制器用于控制雾化器1工作以雾化气溶胶生成基质。主机2还包括电池支架、气流传感器等其他元件。
雾化器1与主机2可以是一体设置，也可以是可拆卸连接，根据具体需要进行设计。
请参阅图2，图2是本申请一实施例提供的雾化器的结构示意图。
雾化器1包括吸嘴组件11、雾化管12、通气管13、发热组件14和连接座15。其中，雾化管12和通气管13构成储液组件，以形成储液腔10。储液组件具有储液腔10和进液孔130。具体地，雾化管12包括相对的第一端(图未示)和第二端(图未示)；吸嘴组件11设于雾化管12的第一端，连接座15设于雾化管12的第二端。通气管13设于雾化管12内，雾化管12的内表面与通气管13的外表面之间形成储液腔10。其中，吸嘴组件11、雾化管12、通气管13、连接座15配合形成封闭的储液腔10，储液腔10用于存储气溶胶生成基质。发热组件14设于储液组件内，具体地，发热组件14设于通气管13内，通气管13的管壁设有进液孔130，发热组件14通过进液孔130与储液腔10流体连通，以使发热组件14雾化气溶胶生成基质生成供用户吸食的气溶胶。可以理解，其中的封闭指的是除了储液腔10可以通过进液孔130向发热组件14供液，其他地方为封闭的。
在本实施例中，发热组件14包括多孔导液件141和发热体142；多孔导液件141和发热体142均为环状体，发热体142贴合设于多孔导液件141的内表面。储液腔10中的气溶胶生成基质通过进液孔130流入多孔导液件141，多孔导液件141利用其毛细作用力将气溶胶生成基质导引至发热体142，被发热体142加热雾化生成气溶胶。发热体142围设形成的空间定义为雾化腔140。也就是说，发热组件14为环状体，发热组件14的内部空间为雾化腔140。多孔导液件141的外表面与通气管13的内表面贴合设置，以避免经过进液孔130的气溶胶生成基质从多孔导液件141的外表面与通气管13的内表面之间漏出。其中，多孔导液件141可以是多孔陶瓷、棉芯等，发热体142可以是发热膜、发热丝、发热网等。多孔导液件141不限于环状，也可以采用片状结构。
在其他实施例中，发热组件14可以为多孔导电陶瓷，多孔导电陶瓷同时具有导液和加热雾化功能。发热组件14为环状体，发热组件14的内部空间定义为雾化腔140。发热组件14的外表面与通气管13的内表面贴合设置，以避免经过进液孔130的气溶胶生成基质从 多孔导液件141的外表面与通气管13的内表面之间漏出。
发热组件14还包括第一电极和第二电极，第一电极和第二电极通过连接座15与主机2实现电连接。在一实施方式中，连接座15上设有第一导通件(图未示)和第二导通件(图未示)，第一导通件将发热组件14的第一电极与主机2的一电极电连接，第二导通件将发热组件14的第二电极与主机2的另一电极电连接；第一导通件和第二导通件可以是顶针、弹针等。在另一实施方式中，连接座15包括第一环形导电件(图未示)、环形绝缘件(图未示)和第二环形导电件(图未示)，环形绝缘件设于第一环形导电件和第二环形导电件之间，以将第一环形导电件和第二环形导电件绝缘；发热组件14的第一电极通过第一环形导电件与主机2的一电极电连接，发热组件14的第二电极通道第二环形导电件与主机2的另一电极电连接。
吸嘴组件11形成有第一通道110。通气管13形成有第二通道131。第二通道131将雾化腔140与第一通道110连通。连接座15上设有第三通道150，第三通道150将外界气体与雾化腔140连通。也就是说，雾化器1中的气体流向为：外界气体经第三通道150进入雾化腔140，携带雾化腔140中的气溶胶生成基质经第二通道131进入第一通道110，最终被用户吸食。
雾化器1还包括预热件16。预热件16设于雾化管12与通气管13之间，且预热件16位于通气管13设有进液孔130的附近，也就是说，预热件16设于储液腔10内；预热件16用于对气溶胶生成基质进行预热，以降低进液孔130附近的气溶胶生成基质的粘稠度，使得进液孔130附近的气溶胶生成基质的流动性较好，保证对发热组件14的充足供液，避免出现干烧、焦味。其中，预热件16的材质为金属。
可以理解，本申请的雾化器1不限于上述结构，也可以采用其他结构，只要在储液腔10内的进液孔130附近设置预热件16即可。预热件16可以用于传导发热组件14的热量，也可以主动发热。
在一实施方式中，预热件16为环状，预热件16围绕通气管13一周设置，预热件16遮挡进液孔130且与通气管13间隔设置；通过 将预热件16设为环状，使得气溶胶生成基质在进入进液孔130之前，沿着通气管13周向上的气溶胶生成基质预热的热量是均匀的。在另一实施方式中，雾化器1包括多个预热件16，预热件16与进液孔130的数量是相同的，一个进液孔130附近设置一个预热件16；预热件16在通气管13的投影覆盖一个进液孔130的至少部分，能够对即将进入进液孔130的气溶胶生成基质进行预热即可。
在一实施方式中，通气管13与发热组件14导热连接，预热件16与通气管13导热连接。通气管13和预热件16的材质为金属，导热性好。发热组件14加热产生的热量传导至通气管13上，通气管13上的热量传导至预热件16。将预热件16设为与通气管13间隔设置，使得预热件16和通气管13从两侧对进液孔130附近的气溶胶生成基质进行预热，使得该部分气溶胶生成基质预热的热量更均匀，进一步保证了发热组件14的充足供液。预热件16可以与雾化管12贴合设置，也可以与雾化管12间隔设置；当预热件16与雾化管12间隔设置，预热件16上设有过液孔163，位于预热件16与雾化管12之间的气溶胶生成基质可以通过过液孔163流至预热件16与通气管13之间，并通过进液孔130到达发热组件14(如图3所示)。可选的，预热件16上的过液孔163与通气管13上的进液孔130同轴对齐。
可选的，预热件16与通气管13一体成型(请参阅图3，图3是图2提供的雾化器中通气管与发热组件的一装配结构示意图)。如图3所示，预热件16与通气管13平行设置，预热件16与通气管13间隔设置。当预热件16为环状时，预热件16套设在通气管13的外侧。由于预热件16与通气管13一体成型，在对通气管13打孔形成进液孔130的时候在预热件16对应处也形成了过液孔163。通过将预热件16与通气管13一体成型，便于加工和装配。
可选的，预热件16可以与连接座15一体成型(请参阅图4，图4是图2提供的雾化器中通气管、发热组件与连接座的一装配结构示意图)。预热件16与通气管13平行设置，预热件16与通气管13间隔设置，通气管13的端部与连接座15接触，通气管13将热量传导至连接座15，进而使预热件16具有一定热量进行预热。如图4所示， 预热件16为环状，预热件16套设在通气管13的外侧。通过将预热件16与连接座15一体成型，便于加工和装配。
可选的，预热件16可以为固定于通气管13上的独立元件，预热件16与通气管13直接接触(请参阅图5，图5是图2提供的雾化器中预热件、发热组件与通气管的一装配结构示意图)。具体地，预热件16包括相互连接的第一部分161和第二部分162，第一部分161与通气管13平行设置，第二部分162与通气管13垂直设置。如图5所示，第一部分161为环形侧壁，第二部分162为连接环形侧壁的底壁且具有通孔；预热件16的第一部分161套设在通气管13外侧，即，预热件16的第一部分161与通气管13间隔设置；预热件16的第二部分162套设在通气管13外侧且与通气管13垂直设置，且预热件16的第二部分162的通孔侧壁与通气管13接触。可以理解，预热件16的第一部分161的延伸方向也可以与通气管13的延伸方向呈小于45度的夹角。
可选的，预热件16可以为固定于连接座15上的独立元件，通气管13与连接座15接触。预热件16与通气管13平行设置，预热件16与通气管13间隔设置。当预热件16为环状时，预热件16套设在通气管13的外侧。通气管13的端部与连接座15接触，通气管13将热量传导至连接座15，连接座15将热量传导至预热件16，使其具有一定热量进行预热。
在另一实施方式中，预热件16可以自发热。具体地，预热件16通过连接座15与主机2电连接，通过主机2的电池供能实现自发热；即，预热件16用于在通电后发热。例如，连接座15可以包括相互套设且彼此绝缘的两个导电元件，两个导电元件分别将预热件16的正负极连接至主机2。预热件16通过连接座15与主机2实现电连接的方式可参考发热组件14通过连接座15与主机2实现电连接的方式，不再赘述。预热件16与通气管13平行设置，预热件16固定于通气管13和/或连接座15上。将通气管13设置为与发热组件14导热连接，预热件16与通气管13间隔设置，使得预热件16和通气管13从两侧对进液孔130附近的气溶胶生成基质进行预热，使得该部分气溶 胶生成基质预热的热量更均匀。预热件16可以与雾化管12贴合设置，也可以与雾化管12间隔设置；当预热件16与雾化管12间隔设置，预热件16上设有过液孔(图未示)，位于预热件16与雾化管12之间的气溶胶生成基质可以通过过液孔流至预热件16与通气管13之间。
继续参阅图5，通气管13包括第一管段132和第二管段133。进液孔130设于第二管段133。发热组件14设于第二管段133内，且与第二管段133接触。预热件16与第二管段133导热连接，即，预热件16与第二管段133接触。可选的，通气管13的第二管段133位金属，第一管段132的材质根据需要进行设计。其中，第一管段132形成第二通道131。如图5所示，第二管段133的直径大于第一管段132的直径，通过该设计，使得通气管13在能够容置下发热组件14的同时增大了储液腔10的储液量。可以理解，在本实施例中，通气管13均为上述结构，只是以图5所示结构为例进行了介绍。
继续参阅图2，连接座15用于与主机2连接的端部形成缩口，且其外表面设有螺纹。雾化器1通过连接座15上的螺纹与主机2实现可拆卸连接。通过将连接座15的端部设为缩口，使得雾化器1与主机2连接后，雾化器1的外表面和主机2的外表面平齐。雾化管12的端面与连接座15抵接。
请参阅图6，图6是本申请另一实施例提供的雾化器的结构示意图。
图6提供的雾化器的结构与图2提供的雾化器的结构基本相同，不同之处在于，雾化管12与连接座15的连接方式。
雾化器1包括吸嘴组件11、雾化管12、通气管13、发热组件14、连接座15和预热件16。雾化管12包括相对的第一端(图未示)和第二端(图未示)；吸嘴组件11设于雾化管12的第一端，连接座15设于雾化管12的第二端。通气管13设于雾化管12内，雾化管12的内表面与通气管13的外表面之间形成储液腔10。具体地，吸嘴组件11、雾化管12、通气管13、连接座15配合形成封闭的储液腔10，储液腔10用于存储气溶胶生成基质。发热组件14设于通气管13内，通气管13设有进液孔130，发热组件14通过进液孔130与储液腔10 流体连通，以使发热组件14雾化气溶胶生成基质生成供用户吸食的气溶胶。可以理解，其中的封闭指的是除了储液腔10可以通过进液孔130向发热组件14供液，其他地方为封闭的。
预热件16设于雾化管12与通气管13之间，且预热件16位于通气管13设有进液孔130的附近，也就是说，预热件16设于储液腔10内；预热件16用于对气溶胶生成基质进行预热，以降低进液孔130附近的气溶胶生成基质的粘稠度，使得进液孔130附近的气溶胶生成基质的流动性较好，保证对发热组件14的充足供液，避免出现干烧、焦味。
预热件16的设置方式，预热件16与雾化管12、通气管13之间的位置关系、连接方式如上所述，不再赘述。
在本实施例中，雾化管12靠近连接座15的端部向内部弯曲形成弯曲部121，弯曲部121用于与连接座15接触。可选的，在雾化管12的弯曲部121与连接座15之间设有密封件17。
在另一实施例中，连接座15可以与通气管13直接接触，预热件16与弯曲部121接触连接，例如预热件16与弯曲部121一体成型。
在另一实施例中，弯曲部121可以与通气管13直接接触，预热件16与弯曲部121接触连接，例如预热件16与雾化管12一体成型。
以上仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
