具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请中的术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”、“第三”的特征可以明示或者隐含地包括至少一个特征。本申请的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。本申请实施例中所有方向性指示(诸如上、下、左、右、前、后……)仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果特定姿态发生改变时，则方向性指示也相应地随之改变。本申请实施例中的术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、***、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或组件。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
对于底部直冲进气影响雾化量的问题，本申请的申请人开发了雾化面朝上的雾化器，但其进气方式的设计成为了新的挑战。
请参阅图1(a)至图1(d)，图1(a)是雾化面朝上的雾化器在雾化腔二侧单气道进气时气溶胶的状态拟合示意图；图1(b)是图1(a)的雾化器的气流状态拟合示意图；图1(c)是图1(a)的雾化器气溶胶体积分数拟合示意图；图1(d)是10um粒径大液滴在图1(a)的雾化器的雾化腔及出气通道的追踪示意图。若设计为对称的对冲进气方式，容易在发热元件的中心区域形成“滞止区”，气溶胶难以被带走。同时在进气口附近的漩涡会导致炸油液滴被带入到涡流中心区域，导致了液滴在雾化腔壁面的黏附；若设计为非对称的进气方式，则会导致液滴被直接吹向进气口相对的壁面，无法随主气流到达外界。
与此同时，气溶胶受到气道内的涡流作用与壁面接触发生凝结，导致了冷凝液的生成。
本申请的申请人在上述技术手段的基础上，持续改进和优化，提出了以下实施例：

在另一可选实施例中，提供的电子雾化装置100包括壳体11、安装座12、雾化芯16和电源组件21。其中，储液仓、安装座12、雾化芯16和电源组件21一体设置，不可拆卸连接。

请参阅图9至图12，图9是本申请提供的雾化器中雾化腔与出气通道中气溶胶的状态拟合示意图；图10是本申请提供的雾化器中雾化腔与出气通道中的气流状态拟合示意图；图11是本申请提供的雾化器中雾化腔与出气通道中气溶胶体积分数拟合示意图；图12是本申请提供的雾化器中10um粒径大液滴的追踪示意图。安装座12上设置有主进气部124和次进气部127。主进气部124和次进气部127用于将安装座12外部的气体传输至雾化腔133，以调节输送至出气通道113的气溶胶的气流，避免气溶胶的气流与出气通道113的内壁面接触，进而减小冷凝液，提升雾化量。具体地，气溶胶的气流从雾化腔133进入出气通道113时，次进气部127控制外部输入的气体在出气通道113的内壁面上形成阻隔层，以使气溶胶的气流形成的气柱直径变小。
参见图4和图6，具体地，主进气部124和次进气部127设置于上座体121上。具体地，主进气部124和次进气部127设置于上座体121不属于下液孔131的环形侧壁122上。主进气部124邻近雾化面166设置，主进气部124用于使外界气体进入雾化腔133并调节气体携带气溶胶以出气通道113的中心轴为圆心形成主流气柱，次进气部127设置于主进气部124远离雾化面166的一侧，次进气部127用于使外界气体进入雾化腔133并调节气体在出气通道113的内壁上形成阻隔层。其中，阻隔层为空气膜。出气通道113的内径一定，次进气部127传输的气体在出气通道113的内壁上形成阻隔层可以减小主流气柱的直径，以避免气溶胶与出气通道113的内壁面接触，进而提升雾化量。
在一具体实施例中，主进气部124的进气方向与次进气部127的进气方向相互平行且处于同一纵切面上。主进气部124的进气方向与次进气部127的进气方向平行于雾化面166。在另一具体实施例中，主进气部124的进气方向和次进气部127的进气方向也可以非相互平行设置。
参见图4，具体地，主进气部124至少包括第一通孔125和第二通孔126，第一通孔125和第二通孔126分别设置于安装座12相对的两个侧壁上，即环形侧壁122相对设置的两部分上。第一通孔125和第二通孔126的形状和尺寸不限。在一实施例中，第一通孔125和/或第二通孔126的形状为矩形，矩形与雾化器1的中轴线平行的边的长度H1不大于矩形与雾化器1的中轴线垂直的边的长度L1。第一通孔125或第二通孔126与雾化器1的中轴线垂直的边的长度为第一通孔125和或第二通孔126的宽度。在一优选实施例中，第一通孔125和/或第二通孔126的中轴线与雾化面166处于同一平面。通过第一通孔125和/或第二通孔126进入雾化腔133的气流用于携带气溶胶进入出气通道113且在雾化腔133内形成涡流区.
请参阅图13(a)至图13(d)，图13(a)是本申请提供的雾化器中第一通孔与发热元件的宽度比例为1:2时的结构示意图；图13(b)是本申请提供的雾化器中第一通孔与发热元件的宽度比例为1:1时的结构示意图；图13(c)是本申请提供的雾化器中第一通孔与发热元件的宽度比例为1:2时的气流状态拟合示意图；图13(d)是本申请提供的雾化器中第一通孔与发热元件的宽度比例为1:1时的气流状态拟合示意图。在一可选实施例中，第一通孔125和/或第二通孔126的宽度L1等于发热元件162的分布宽度W1。第一通孔125和第二通孔126的宽度方向为垂直于雾化器1中轴线的方向。发热元件162的宽度方向为两个下液孔131的连线方向。在一 可选实施例中，第一通孔125和第二通孔126的形状为矩形时，第一通孔125和第二通孔126垂直雾化器1的中轴线的边的长度等于发热元件162的宽度。在另一可选实施例中，第一通孔125和第二通孔126的形状为圆形，第一通孔125和第二通孔126的直径等于发热元件162的宽度。
当第一通孔125和第二通孔126的宽度等于发热元件162的分布宽度时，第一通孔125和第二通孔126传输进雾化腔133中的气体可以将雾化面166生成的气溶胶更多的带离雾化面166。第一通孔125和第二通孔126的宽度等于发热元件162的分布宽度可以扩大输送至雾化腔133的气体的覆盖面，同时提高气体进入雾化腔133时的作用力，以便于将雾化腔133中的气溶胶集中于出气通道113的中轴线上，使得气溶胶形成的气柱横截面减小，避免气溶胶在出气通道113中扩散。第一通孔125和第二通孔126的进气可以覆盖发热元件162生成的气溶胶所有表面，充足的进气量可以将雾化面166产生的大尺寸液滴的气溶胶携带至出气通道113并送入用户口中，避免大液滴气溶胶由于重力作用回落至雾化面166形成冷凝液。其中，大液滴的粒径为10-170um。
在一具体实施例中，第一通孔125的位置和第二通孔126的位置可以相对设置。在一具体实施例中，第一通孔125的中轴线和第二通孔126的中轴线重合且平行于雾化面166。第一通孔125的位置和第二通孔126的位置也可以错位设置于上座体121的环形侧壁122上。在一具体实施例中，第一通孔125的位置可以与第二通孔126的位置可以纵向错位，也可以横向错位。第一通孔125的结构和第二通孔126的结构可以相同，也可以不同。第一通孔125与第二通孔126的形状可以相同，也可以不同。在另一可选实施例中，第一通孔125和第二通孔126的位置可以错位设置，第一通孔125和第二通孔126至少部分相对设置。当第一通孔125和第二通孔126的位置对称时，雾化面166附近形成的停滞区域处于雾化器1的中轴线上；当第一通孔125和第二通孔126的位置称非对称设置时，雾化面166附近形成的停滞区域偏离雾化器1的中轴线。
次进气部127至少包括第三通孔128和第四通孔129，第三通孔128和第四通孔129设置于安装座12相对的两个侧壁上。第三通孔128和/或第四通孔129设置于上座体121上，且设置于第一通孔125和第二通孔126远离下座体141的一侧。在一具体实施例中，第三通孔128和/或第四通孔129设置于出气孔132安装出气通道113的部分侧壁上。出气通道113的端面作为第三通孔128和第四通孔129的部分侧壁。第三通孔128和第四通孔129的靠近出气孔132内壁的端口与出气通道113的内壁面和第一腔体134的内壁面平齐，避免第三通孔128和第四通孔129与出气通道113的端面之间形成死角。通过第三通孔128和第四通孔129进入雾化腔133的气流用于吹散雾化腔133内滞留的涡流区，以使涡流区中的气溶胶进入出气通道113。第三通孔128和第四通孔129靠近雾化腔133的端口与出气通道113的内壁面平齐，可以使得从第三通孔128和第四通孔129进入的气体可以更顺畅的进入出气通道113，并在出气通道113的内壁面上形成阻隔层，避免气溶胶与出气通道113的内壁面接触。
在一具体实施例中，第三通孔128和/或第四通孔129的中轴线与雾化面166所处平面相互平行。在另一具体实施例中，第三通孔128和/或第四通孔129靠近雾化腔133的一端与雾化面166所处平面之间的距离大于第三通孔128和/或第四通孔129远离雾化腔133的一端与雾化面166平面之间的距离。在另一可选实施例中，第三通孔128和/或第四通孔129靠近雾化腔133的一端与雾化面166所处平面之间的距离小于第三通孔128和/或第四通孔129远离雾化腔133的一端与雾化面166平 面之间的距离。
在一具体实施例中，第三通孔128的位置和第四通孔129的位置可以相对设置。在一具体实施例中，第三通孔128的中轴线和第四通孔129的中轴线重合且平行于雾化面166。第三通孔128的位置和第四通孔129的位置也可以错位设置于上座体121的环形侧壁122上。在一具体实施例中，第三通孔128的位置可以与第四通孔129的位置纵向错位，也可以横向错位。第三通孔128的结构和第四通孔129的结构可以相同，也可以不同。第三通孔128与第四通孔129的形状可以相同，也可以不同。在另一可选实施例中，第三通孔128和第四通孔129的位置可以错位设置，第三通孔128和第四通孔129的至少部分相对设置。在一优选实施例中，第三通孔128和/或第四通孔129的形状为矩形，矩形与雾化器1的中轴线平行的边的长度不大于矩形与雾化器1的中轴线垂直的边的长度。
第三通孔128与第一通孔125，第四通孔129与第二通孔126可以相对设置，也可以错位设置。在一具体实施例中，第三通孔128与第一通孔125，第四通孔129与第二通孔126可以在雾化器1的中心轴方向上错位。
通孔的高度方向为沿雾化器1的中心轴延伸的方向。当第一通孔125和/或第二通孔126的高度较小时，第一通孔125和/或第二通孔126的气流流速较小，雾化面166附近会形成更大的停滞区域，停滞区域的气溶胶难以被带到外界。当第三通孔128和/或第四通孔129的高度较大时，通过第一通孔125和/或第二通孔126传输的气体与第二腔体135内壁形成的涡流区域变小，使得雾化腔133中的气溶胶的通过率增加。在一具体实施例中，请参阅图14和图15，图14是本申请提供的第三通孔的高度为0.3mm时雾化腔与出气通道中气溶胶的流速等值线示意图；图15是本申请提供的第三通孔的高度为0.6mm时雾化腔与出气通道中气溶胶的流速等值线示意图。当第一通孔125和/或第二通孔126的高度分别为0.3mm，第三通孔128和/或第四通孔129的高度从0.3mm增加到0.6mm时，第三通孔128和/或第四通孔129的高度增加，第三通孔128和/或第四通孔129中的气体冲击第一通孔125和/或第二通孔126与雾化腔133的内壁形成的涡流区域，第一通孔125和/或第二通孔126处于雾化腔133的内壁形成的涡流区域有所减小。由于第三通孔128和/或第四通孔129进入的气体会给第一通孔125和第二通孔126进入的气体一定的压力，以使第一通孔125和/或第二通孔126进入的气体所携带的气溶胶一定程度上被挤压，使得雾化面166的附近形成的停滞区域略有增大，进而影响气溶胶的通过率。因此，第一通孔125、第二通孔126、第三通孔128和第四通孔129的高度可以根据气溶胶的通过率来进行设计。
环形侧壁122的外壁面上设置有集液槽137，集液槽137用于收集从主进气部124和次进气部127中漏出的液体，也用于收集进气空间151漏出的液体。
请参阅图16，图16是本申请提供的雾化器中下座体一实施例的结构示意图。下座体141设置于上座体121远离出气通道113的一侧，且与上座体121固定连接，具体的，上座体121可以与下座体141卡接。在一具体实施例中，下座体141包括基板142以及设置于基板142靠近雾化芯16一表面的支撑组件145。在一具体实施例中，支撑组件145包括第一支撑臂146和第二支撑臂147，第一支撑臂146和第二支撑臂147相对且间隔设置于基板142上。第一支撑臂146与第二支撑臂147相对的表面设有凸台148。凸台148用于支撑雾化芯16，凸台148与雾化芯16远离雾化面166的一侧接触。凸台148上设有第一毛细槽149，第一毛细槽149用于接收雾化芯16中遗漏的液体。基板142上设置有进气孔144，基板142与雾化芯16之间间隔设置并形成有进气空间151，环形侧壁122与壳体11之间形成进气通道150， 进气通道150一端与进气空间151连通，另一端与主进气部124和次进气部127连通。基板142设有第一支撑臂146和第二支撑臂147的表面设置有第二毛细槽143，第二毛细槽143与第一毛细槽149连通。第二毛细槽143用于存储第一毛细槽149遗漏的漏液以及通过雾化芯16漏出的漏液。第一支撑臂146第二支撑臂147用于连接上座体121。
本实施例提供的一种电子雾化装置，其中该雾化器包括：壳体，壳体具有储液腔、安装腔和出气通道；安装座，至少部分收容于安装腔；雾化芯，安装于安装座内，雾化芯与储液腔连通，雾化芯的雾化面与出气通道相对且间隔设置，且雾化芯与出气通道之间形成雾化腔。本申请通过在雾化腔的侧壁上设置有主进气部和次进气部，主进气部靠近雾化芯设置，次进气部靠近出气通道设置，通过主进气部进入雾化腔的气流用于携带气溶胶进入出气通道且在雾化腔内形成涡流区；通过次进气部进入雾化腔的气流用于吹散雾化腔内滞留的涡流区，以使涡流区中的气溶胶进入出气通道，同时次进气部进入雾化腔中的气体在出气通道的内壁上形成阻隔层，以使携带气溶胶的气流与出气通道的内壁不接触，进而避免气溶胶与出气通道的内壁面接触形成冷凝液，进而提升气溶胶的雾化量。
以上仅为本申请的实施方式，并非因此限制本申请的专利保护范围，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。
