请参阅图2、图3和图4，图2是本实施例提供的雾化器第一实施例的一种立体结构示意图，图3为图2的雾化器的爆炸结构示意图，图4为图2的雾化器沿A-A向的剖视图。
本实施例中，提供一种雾化器11，该雾化器11包括壳体111、安装座112、雾化芯113和端盖114。
其中，壳体111内形成有储液腔1111、出气通道1112和安装腔1113，储液腔1111和出气通道1112分别与安装腔1113连通。
储液腔1111用于储存气溶胶产生基质，壳体111可以由铝、不锈钢等金属制成，也可以由塑料制成，只需能储存气溶胶产生基质，且不与气溶胶产生基质反应即可。储液腔1111的形状、大小和位置不限，可以根据需要进行设计。本实施例中，储液腔1111与出气通道1112并排设置在安装腔1113的同一侧，且储液腔1111环绕出气通道1112设置。

请参阅图3和图4，安装顶盖1121的顶壁1121a上具有出气孔1121c，出气孔1121c的一端与雾化腔1123连通，出气孔1121c的另一端与出气通道1112连通，以使雾化腔1123与出气通道1112连通。雾化芯113雾化后的气溶胶与冷空气混合后流入出气通道1112。进一步地，出气通道1112远离安装腔1113的一端具有出气口1112a，即，出气通道1112的一端的端口为出气口1112a，出气通道1112通过出气口1112a与外界大气连通，以使出气通道1112中的气溶胶能流出雾化器11提供给用户使用。
请参考图7，图7为图3中雾化芯的一种立体结构示意图；
其中，雾化芯113包括基体1133、发热层1134和两个电极1135。基体1133靠近储液腔1111的一侧具有雾化面1131，即，雾化芯113具有雾化面；发热层1134和两个电极1135设于雾化面1131上。基体1133可以储存和导流气溶胶产生基质。基体1133的材料可以是多孔材料，例如多孔陶瓷，多孔陶瓷可以利用毛细作用力将气溶胶产生基质导引至发热层1134上，发热层1134能对其加热雾化形成气溶胶。发热层1134可以是发热丝、发热网、发热膜、发热线路等，可以根据需要进行选择。两个电极1135设于发热层1134的两端，两个电极1135可以通过连接件与电池组件12电连接，以使两个电极1135通电后，两个电极 1135之间的发热层1134通电加热气溶胶产生基质。
在本实施方式中，雾化芯113的雾化面面向安装座112的出气孔1121c，即，雾化面朝上设置。
请参考图3和图4，雾化器11还包括第一密封件115、第二密封件116和第三密封件117。第一密封件115设于安装顶盖1121靠近储液腔1111的一端，以实现安装顶盖1121与壳体111之间的密封。第二密封件116套设于雾化芯113上，以实现雾化芯113与安装顶盖1121之间的密封。第三密封件117设于安装底座1122与雾化芯113之间，以实现雾化芯113与安装底座1122之间的密封，以及安装顶盖1121与安装底座1122之间的密封。第一密封件115、第二密封件116和第三密封件117的材质可以为任何具有一定柔性且可以耐一定温度的密封材料。本实施例中，第一密封件115、第二密封件116和第三密封件117的材质为硅胶。第一密封件115、第二密封件116和第三密封件117的形状和大小不限，可以根据需要进行设计。
请参阅图5和图8，图8为图3中安装座和雾化芯装配后的一种剖视图。
其中，安装顶盖1121的顶壁1121a上还设有下液孔1121d，下液孔1121d的一端与储液腔1111连通，下液孔1121d的另一端与雾化腔1123连通，以使储液腔1111中的气溶胶产生基质能通过下液孔1121d流至雾化腔1123中。下液孔1121d的数量可以为一个或多个，本实施例中，下液孔1121d的数量为两个，且对称设置于出气孔1121c的相对两侧。
在本实施例中，安装座112中具有导液通道1124。具体地，可以是安装顶盖1121中形成导液通道1124，例如可以是安装顶盖1121的侧壁1121b形成导液通道1124，或者，第二密封件116以及第三密封件117与安装顶盖1121的侧壁1121b配合形成导液通道1124，导液通道1124与下液孔1121d连通，以使导液通道1124与储液腔1111连通。导液通道1124可以将储液腔1111中的气溶胶产生基质导流至雾化芯113的侧壁和/或雾化芯113远离出气孔1121c的一面。在本实施例中，导液通道1124将气溶胶产生基质导流至雾化芯113远离出气孔1121c的一面。具体地，第三密封件117靠近雾化芯113的一端设有导液槽1171，导液槽1171与导液通道1124连通。导液槽1171能将导液通道1124中的气溶胶产生基质导流至雾化芯113远离安装顶盖1121的顶壁1121a的一面，以使雾化芯113能加热雾化气溶胶产生基质产生气溶胶。在其他实施例中，也可以是第二密封件116上设置有导液槽1171，以将导液通道1124中的气溶胶产生基质导流至雾化芯113的侧壁。通过设置导液通道1124和导液槽1171，能使储液腔1111中的气溶胶产生基质能流至雾化芯113的侧面或与雾化面1131相对的一面，以使雾化芯113能吸收气溶胶产生基质并将气溶胶产生基质导流至雾化面1131，以加热形成气溶胶。
请参阅图9，图9为图2的雾化器沿B-B向的局部剖视图，图9中的箭头表示雾化器11中的气流路径。
在一种实施例中，安装座112的侧壁1121b与安装腔1113的侧壁1113a配合形成导气通道1125。导气通道1125的一端与雾化器11的进气口1122a连通，以使外界大气能通过雾化器11的进气口1122a进入导气通道1125中；导气通道1125的另一端与雾化腔1123连通，以使导气通道1125中的气流能进入雾化腔1123中。
进一步地，安装座112开设有进气孔1125a，可以是安装顶盖1121的侧壁1121b上开设有进气孔1125a，进气孔1125a的一端与导气通道1125连接，另一端与雾化腔1123连通，以使导气通道1125中的气流通过进气孔1125a进入雾化腔1123中。进气孔1125a可以设于雾化面1131朝向出气孔1121c的一侧，例如，进气孔1125a可以设置于雾化面1131与出气孔1121c之间，以使进入雾化腔1123中的气流能携带雾化芯113的雾化面1131产生的气溶胶，经由出气孔1121c流至出气通道1112，最终从出气口1112a流出雾化器11供用户使用。
具体地，请参考图5和图10，图10为图3中安装座和雾化芯装配后的另一种剖视图。
本实施例中，安装顶盖1121的侧壁1121b的外表面设有导气槽1121e，安装腔1113的侧壁1113a与导气槽1121e的底壁配合形成导气通道1125，导气通道1125靠近安装顶盖1121的顶壁1121a的一侧设有进气孔1125a。在其他实施例中，也可以是安装腔1113的侧壁1113a设置导气槽1121e，安装座112的侧壁1121b与导气槽1121e的底壁配合形成导气通道1125。导气通道1125的形成方式不限于上述提到的方式。
在一种实施例中，请参考图5和图6，导气槽1121e的一端为封闭端，靠近安装顶盖1121的顶壁1121a设置；导气槽1121e的另一端为敞口端，延伸至安装顶盖1121的底面1121f。 导气槽1121e的形状可以是如本实施例的长方形，也可以是其他的形状。导气槽1121e的数量可以为一个或多个。本实施例中，导气槽1121e的数量为两个，分别设置于安装顶盖1121相对的两个侧壁1121b的外表面上。两个导气槽1121e分别与安装腔1113的侧壁1113a形成两个导气通道1125，两个导气通道1125均与雾化器11的出气口1112a连通。两个导气槽1121e中的每个导气槽1121e靠近安装顶盖1121的顶壁1121a的一端设有进气孔1125a。从出气口1112a进入雾化器11的气流经由两个导气通道1125流至雾化腔1123中。
本实施例中，导气槽1121e靠近安装顶盖1121的顶壁1121a一端的底面1121g向安装顶盖1121的内部倾斜，同时，进气口1122a设置于导气槽1121e靠近安装顶盖1121的顶壁1121a的端部。导气槽1121e靠近安装顶盖1121的顶壁1121a一端的深度增大，且越靠近安装顶盖1121的顶壁1121a，导气槽1121e的深度越大，以使导气通道1125的气流更容易从导气通道1125导流至出气孔1121c中。在其他实施例中，还可以是导气槽1121e的全部底面1121g向安装顶盖1121的内部倾斜。
进气孔1125a的宽度可以小于导气槽1121e的宽度，也可以等于导气槽1121e的宽度。本实施例中，进气孔1125a的宽度等于导气槽1121e的宽度。进气孔1125a的宽度越宽，进气孔1125a能通过的气流量越大，有利于增大从出气口1112a流出的气溶胶量。
如图10所示，进气孔1125a与雾化芯113的雾化面1131之间具有间距。具体的，雾化面1131与进气孔1125a靠近雾化面1131的底面1125b之间具有间距，且间距的距离为h。
请参考图11，图11为图2的雾化器内气体的局部流速图，具体的，为图11中所示的为雾化腔1123处的局部流速图。雾化面1131产生的气溶胶会在雾化面1131附近形成涡流区域，其中，涡流区域为虚线框围设的区域。从导气通道1125流入雾化腔1123中的冷空气会和雾化面1131生成的热的气溶胶进行热对流。
从图11可以看出，当h＝0时，即进气孔1125a与雾化芯113的雾化面1131之间不具有间距时，雾化面1131附近的涡流区域较小，冷空气与热的气溶胶之间的热对流较大，冷空气与气溶胶混合后的气流温度较高，流出雾化器11的出气口1112a的气溶胶的温度较高，导致用户的使用体验较差。
从图11还可以看出，当h＞0时，即进气孔1125a与雾化芯113的雾化面1131之间具有间距时，相比于h＝0的结构，雾化面1131附近的涡流区域增大，且h的值越大，即间距越大，雾化面1131附近的涡流区域越大。因此，通过在进气孔1125a与雾化芯113的雾化面1131之间设置间距，雾化面1131附近的涡流区域的增大减少了冷空气与热的气溶胶之间的热对流，从而使冷空气与气溶胶混合后的气流温度降低，流出雾化器11的出气口1112a的气溶胶的温度减小，提升了用户的使用体验。
进一步请参考图12，图12为图2的雾化器内局部温度分布图，具体的，为图12中所示的为雾化腔1123处的局部温度图。从图12可以看出，当h＝0时，涡流区域较小，与冷空气对流的气溶胶的温度较高，使得冷空气与气溶胶混合后的气流温度较高，流出雾化器11的出气口1112a的气溶胶的温度较高，导致用户的使用体验较差。当h＞0时，雾化面1131附近的涡流区域增大，相比于h＝0时，与冷空气对流的气溶胶的温度有所降低，且h的值越大，涡流区域越大，与冷空气对流的气溶胶的温度越低。因此，通过在进气孔1125a与雾化芯113的雾化面1131之间设置间距，能使冷空气与气溶胶混合后的气流温度降低，流出雾化器11的出气口1112a的气溶胶的温度减小，从而提升了用户的使用体验。
具体的，h的值不能过大，当h的值过大时，气溶胶的涡流区域过大，与冷空气对流的气溶胶过少，会使得流出雾化器11的出气口1112a的气溶胶量过小。
在本实施例中，实验所采用的雾化器11参数如下：出气通道1112的直径是2.5mm，长度29.4mm，雾化芯113上的S型发热层1134的温度初始温度250°，雾化量是3s/9mg，电池组件12对雾化芯113的输入功率是6.5W。当然，我们也可以采用其他具有不同参数的雾化器11，但是仍可以通过实验结果绘制具有相似数学关系的间距-出气口的气溶胶的烟雾量的曲线图。
可以参考表1、图13以及图14，表1为h分别为0mm、0.1mm、0.2mm、0.3mm、0.4mm、0.5mm、0.6mm、0.7mm时，流出雾化器11的出气口1112a的气溶胶的温度和气溶胶量的实验结果；图13为根据表1的实验结果绘制的间距-出气口1112a的气溶胶的温度曲线图，图14为根据表1的实验结果绘制的间距-出气口的气溶胶量的曲线图。

Figure PCTCN2022129351-appb-000001
从实验结果可以看出，当h＝0时，流出雾化器11的出气口1112a的气溶胶量较大，但雾化器11的出气口1112a的气溶胶的温度较高，导致用户的体验较差。当h＞0时，流出雾化器11的出气口1112a的气溶胶的温度降低，且h越大，流出雾化器11的出气口1112a的气溶胶的温度明显降低，但流出雾化器11的出气口1112a的气溶胶量随着h的增大呈降低的趋势。当h＝0.7时，流出雾化器11的出气口1112a的气溶胶量降低至7.19mg/puff。
因此，可以设置雾化面1131与进气孔1125a之间相隔一定距离h，例如，针对以上实验的所用的雾化器，对应h的范围为0mm＜h≤0.7mm。h的值可以为0.1mm、0.2mm、0.3mm、0.4mm、0.5mm、0.6mm、0.7mm等。优选地，0.2mm≤h≤0.5mm。通过设置雾化面1131与进气孔1125a之间的距离h以使得出气口1112a的气溶胶的温度降低，能使雾化面1131与进气孔1125a靠近雾化面1131的底面1125b之间的间距设置在合适的范围，使得流出雾化器11的出气口1112a的气溶胶的温度减小的同时，保证流出雾化器11的出气口1112a的气溶胶的烟雾量不会过少，有利于提升用户的使用体验。
在本实施例中，发明人还尝试通过增加出气通道1112的长度来降低出气口1112a的气溶胶的温度，实验表明：出气通道1112的长度在29.4mm时，发现出气口1112a的气溶胶的温度是93.16°；出气通道1112的长度增长13mm，达到42.4mm时，出气口1112a的气溶胶的温度是87°。虽然温度降低了6.17°，但出气通道1112的长度增长超过50％，这是产品设计所不可接受的，因此，通过设置雾化面1131与进气孔1125a之间相隔一定距离h的技术方案具有明显的性能和效果提高。可以参考图15，图15为h分别为0mm和0.4mm时，流出雾化器11的出气口1112a的气溶胶的温度和气溶胶量的实验结果的柱状图。从图15中可以看出，h＝0mm时，出气口1112a的气溶胶温度为102.7℃，出气口1112a的气溶胶量为7.54mg/puff；h＝0.4mm时，出气口1112a的气溶胶温度为86.4℃，出气口1112a的气溶胶量为7.33mg/puff；h＝0.4mm时，流出雾化器11的出气口1112a的气溶胶的温度大大减小，且流出雾化器11的出气口1112a的气溶胶量不会过小。
在一种实施例中，如图16所示，图16为图3中安装顶盖、雾化芯、第二密封件、第三密封件以及安装底座的一种爆炸结构示意图。
其中，安装底座1122包括底部1122b和支撑部1122c，安装顶盖1121套设于支撑部1122c上并与底部1122b抵接，支撑部1122c设于雾化腔1123中，雾化芯113设于支撑部1122c靠近安装顶盖1121的顶壁的一侧。通过调整支撑部1122c的高度，可以调节雾化芯113的位置，进而调节进气孔1125a与雾化芯113的雾化面1131之间距离h的大小。
在一种实施例中，如图2和图17所示，图17为图3中安装座与端盖的爆炸结构示意图。
其中，端盖114封盖壳体111远离出气口1112a的一端，例如，端盖114可以套设在壳体111远离出气口1112a的一端，壳体111和端盖114可拆卸连接。
进一步地，安装底座1122背离安装顶盖1121的一侧具有进气口1122a，端盖114上设 有通孔1141，通孔1141与外接大气连通，且进气口1122a与通孔1141连通，以使外界大气能进入进气口1122a。
本实施例中，安装底座1122的底部1122b背离支撑部1122c的一面具有第一凹槽1122d，第一凹槽1122d作为进气孔1125a与通孔1141连通。第一凹槽1122d靠近导气槽1121e的一端具有贯穿安装底座1122的底部1122b的第一开孔1122e。第一开孔1122e可以为通孔或位于底部1122b边缘的缺口。第一开孔1122e将第一凹槽1122d与导气槽1121e靠近底部1122b的一端连通，以使气流能从第一凹槽1122d流入导气槽1121e中。
第一开孔1122e的数量可以与导气槽1121e的数量相同。本实施例中，第一开孔1122e的数量为两个，两个第一开孔1122e与两个导气槽1121e相对设置，两个第一开孔1122e分别将第一凹槽1122d与两个导气槽1121e连通。
在一种实施例中，如图17和图18所示，图18为图3中安装顶盖、雾化芯、第二密封件、第三密封件以及安装底座的另一种爆炸结构示意图。
其中，雾化器11还包括两个电极连接件118，每个电极连接件118的一端与一个电极1135电连接；另一端设置于安装底座1122的底部1122b背离支撑部1122c的表面，且通过端盖114的通孔1141暴露，以使电极连接件118能与电池组件12电连接，从而电池组件12能为雾化芯113供电。在一个实施例中，两个电极连接件118分别设置于所述雾化芯113的两侧，且分别对应电极1135位置设置。即，两个电极连接件118中心旋转对称设置。
进一步地，底部1122b背离支撑部1122c的表面设有两个第二凹槽1122f，分别用于容置两个电极连接件118远离雾化芯113的一端。具体的，第二凹槽1122f靠近壳体111的一侧具有第二开孔1122g，第二开孔1122g可以是底部1122b边缘设置的缺口，每个电极连接件118远离雾化芯113的一端穿过相应的第二开孔1122g设置于相应的第二凹槽1122f中。电极连接件118的设置方式不限于本申请提供的方式，也可以是其他的设置方式，只要能将雾化芯113的两个电极1135与电池组件12电连接即可。
请参考图19，图19为本申请提供的雾化器第二实施例的局部结构示意图。
在雾化器11第二实施例中，雾化器11的结构与雾化器11第一实施例的结构基本相同，不同之处在于：雾化器11包括降温结构119，降温结构119设置于出气通道1112内。其中，降温结构119被配置为降低流经出气通道1112的气溶胶的温度。
通过在出气通道1112内设置降温结构119，以对出气通道1112壁面附近的气溶胶的流动状态进行干涉，使得出气通道1112的壁面的换热系数增大，进而使得流出雾化器11的出气口1112a的气溶胶的温度减小，利于提升用户的使用体验。
可以理解，在设置降温结构119来降低出气口1112a的气溶胶的温度的前提下，雾化芯113的雾化面与进气孔1125a之间的距离h做如上设置(雾化器11第一实施例中具体介绍的内容：雾化芯113的雾化面与进气孔1125a之间的距离h)为可选的。相比于只在出气通道1112内设置降温结构119，在出气通道1112内设置降温结构119的基础上，雾化芯113的雾化面与进气孔1125a之间的距离h做如上设置，可以更好的降低出气口1112a的气溶胶的温度，采用那种方式来降低出气口1112a的气溶胶的温度可以根据具体需要进行设计。
降温结构119一方面可以吸收气溶胶的热量，另一方面可以对出气通道1112近壁面处的流场实现干扰，提高气溶胶与出气通道1112的壁面之间的热交换效率。在一具体实施方式中，降温结构119为螺旋件(图未示)，螺旋件设置于出气通道1112内，且该螺旋件与出气通道1112的内壁面间隔设置，且能够对出气通道1112近壁面处的流场实现干扰，提高气溶胶与出气通道1112的壁面之间的热交换效率，以降低出气口1112a的气溶胶的温度。其中，螺旋件可通过固定结构固定于出气通道1112内。优选，螺旋件的材质为金属弹簧，制作工艺简单，且金属材质较其他材质具有更好的吸热效果，利于进一步降低出气口1112a的气溶胶的温度。
在一具体实施方式中，降温结构119为设置于出气通道1112的内壁面的凸起1191。可选的，凸起1191与出气通道1112的侧壁一体成型；即，类似于波节管结构。可选的，降温结构119为独立元件，在出气通道1112的内设置有螺旋件(图未示)，螺旋件的外壁面贴合出气通道1112的内壁面设置，以使螺旋件作为出气通道1112的内壁面的凸起1191。出气通道1112的内壁面为光滑表面，螺旋件通过螺旋件与出气通道1112之间的摩擦力实现固定；或，出气通道1112的内壁面设置有与螺旋件配合的螺旋槽以实现螺旋件的固定，且螺旋件的线径大于螺旋槽的深度，以形成凸起1191。例如，组装时将螺旋件旋转插入出气通 道1112的螺旋槽内。优选，螺旋件为金属弹簧，金属材质较其他材质具有更好的吸热和导热效果，利于进一步降低出气口1112a的气溶胶的温度。在一个实施例中，金属弹簧的线径为0.2mm-0.3mm，金属弹簧的线径为形成的凸起1191的高度，金属弹簧的匝间距为相邻的凸起1191之间的距离；其中，金属弹簧的线径为制作金属弹簧的金属丝的直径。示例性的，当金属弹簧的线径为0.2mm-0.3mm，金属弹簧的直径为3mm，出气通道1112的长度为28mm时，可以实现较好的降温效果。
可以理解，当凸起1191与出气通道1112的侧壁一体成型时，凸起1191的尺寸设计、以及相邻的凸起1191之间的尺寸设计可参考后续介绍的凸起1191的高度、相邻的凸起1191的中心之间的距离与凸起1191的高度的比值。当通过螺旋件形成凸起1191时，对螺旋件的选择也可参考后续介绍的凸起1191的高度、相邻的凸起1191的中心之间的距离与凸起1191的高度的比值。
请参阅图20-图23，图20为第一实验件的结构示意图，图21为第二实验件的结构示意图，图22为第一实验件出口处的气流温度分布图，图23为第二实验件出口处的气流温度分布图。
图20所示的第一实验件为内壁面光滑的圆管30，圆管30的长度为50mm。圆管30的左侧的端口为入口，圆管30的右侧的端口为出口，气流从入口流向出口。
图21所示的第二实验件为内壁面上设置有凸起31的圆管30，圆管30的长度为50mm，凸起31的高度为0.5mm；其中，沿着凸起31的高度方向，凸起31的截面形状为方形。凸起31沿着圆管30的内表面设置一周。圆管30的左侧的端口为入口，圆管30的右侧的端口为出口，气流从入口流向出口。
使用同样的气体，以相同的流速分别流经第一实验件和第二实验件，得到第一实验件出口处的气流温度(如图22所示)和第二实验件出口处的气流温度(如图23所示)。对于第一实验件出口处的气流温度，从管壁到中心的温度逐渐升高，即，出口处的气流最高温度在中心区域；由图22可知，第一实验件出口处的气流最高温度为84.6℃。对于第二实验件出口处的气流温度，从管壁到中心的温度逐渐升高，即，出口处的气流最高温度在中心区域；由图23可知，第二实验件出口处的气流最高温度为73.3℃。可见，在圆管30的内壁面上设置凸起31使出口处的最高温度降低了13.4％，降温效果明显。也就是说，在出气通道1112的内壁面上设置凸起1191(即，降温结构119)，可以明显降低出气口1112a处气溶胶的温度，利于提高用户的使用体验感。其中，进行实验的气体为气溶胶或其特性与气溶胶相似。
可以理解，将第二实验件中的凸起31沿着圆管30的内表面周向间隔设置，同样可以明显降低出气口处气溶胶的温度。
请参考图24和图25，图24为不同边界层形态对应的局部表面换热系数的变化规律示意图，图25为图19的出气通道内的气流的流动路径示意图。
对于在出气通道1112内设置凸起1191(即，降温结构119)来降低出气口1112a处气溶胶的温度的原理如下：
在图24中，横轴x表示流体与管道入口之间的距离，纵轴h x表示换热系数。流体从管道的入口进入管道，流体进入管道后边界层的形态分为层流边界层、过渡区、湍流边界层，湍流边界层的换热系数要高于层流边界层的换热系数。对于层流边界层形态，层流边界层内的热量传递主要通过热传导方式进行，而空气的热传导系数小，因此换热系数整体上处于较低的水平；且在层流边界层中，随着层流边界层厚度增加换热系数减小。当边界层形态由过渡区转变为充分发展的湍流边界层形态后，湍流边界层内同时存在热传导和热对流两种形式的热量传递，因此局部表面换热系数可以一直维持在较高的数值。由于流体在流动的过程中，会有部分粘附在管道的管壁上，在湍流边界层存在有层流底层。
在出气通道1112的内壁面为光滑的前提下，通常气溶胶在出气通道1112内的流速不大，其近壁面的流动边界层接近层流的形态；在出气通道1112的内壁面增加凸起1191结构后，相当于人为的对近壁面流动边界层进行干扰，使其从规则的层流形态向湍流形态转变，如图25所示，提升了出气通道1112的侧壁与出气通道1112内的气溶胶的换热系数。换热系数提升后有助于气溶胶与出气通道1112的侧壁换热，更多的热量被出气通道1112的侧壁吸收，从而达到降低出气口1112a处气溶胶的温度的目的。
请参考图26和图27，图26为现有的雾化器中出气通道内速度场分布图，图27为本申请提供的雾化器第二实施例中出气通道内速度场分布图。
通常出气通道1112内的流场可分为近壁面区和主流区，气溶胶与出气通道1112的侧壁的换热主要发生在近壁面区。参考图26和图27可知，在出气通道1112的内壁面上设置凸起1191(即，降温结构119)，对近壁面区的气溶胶产生作用较大，使层流边界层状态转变成湍流边界层状态，提升气溶胶与出气通道1112的侧壁之间的换热效率，而主流区中的气溶胶影响较小。由图26和图27可知，近壁面区的流速小于3ms^-1，近壁面区的流速均是越靠近主流区部分的流速越快，主流区的流速大于3ms^-1。也就是说，在出气通道1112的内壁面上设置凸起1191(即，降温结构119)，对出气通道1112的近壁面局部流场产生作用，对于主流区及其他区域的流场影响较小，不会影响用户的气溶胶吸入量。其中，流场为速度场。
在具体实施方式中，凸起1191的高度为0.3mm-0.6mm；和/或，相邻的凸起1191的中心之间的距离与凸起1191的高度的比值为1:20-1:7。通过对凸起1191进行如上尺寸设置，对降低出气口1112a处气溶胶的温度的效果较好。沿着凸起1191的高度方向，凸起1191的截面形状可以是圆形、正方形、长方形、三角形等，具体根据需要进行设计。下面以凸起1191的截面为正方形和圆形为例，对凸起1191的高度、凸起1191的高度与相邻的凸起1191的中心之间的距离的比值进行详细介绍。
请参考图28和图29，图28为图19中凸起的截面为正方形的结构示意图，图29为另一实施方式中凸起的截面为圆形的结构示意图。
在图28中，沿着凸起1191的高度方向，凸起1191的截面为正方形。在图29中，沿着凸起1191的高度方向，凸起1191的截面为圆形。图28和图29中，凸起1191的高度均用“H”表示，相邻的凸起1191的中心之间的距离均用“P”表示。
凸起1191的高度对于换热效率、雾化器11吸阻影响较大，因此可以综合考虑出气口1112a处气溶胶的降温效果、雾化器11的吸阻来对凸起1191的高度进行设计。相邻的凸起1191中心之间的距离影响着出气通道1112的近壁面处的流场，出气通道1112的近壁面处的流场还与凸起1191的高度相关，因此可通过流场分析及凸起1191的高度来对相邻的凸起1191中心之间的距离进行设计。
可以理解，凸起1191尺寸(例如，沿同一方向凸起1191的截面积)相差不大时，截面形状对于吸阻的影响较小。根据雾化器11设计标准的吸阻要求，将凸起1191额外导致的吸阻上限设定为100Pa。以凸起1191的截面为正方形为例，对凸起1191的高度、出气通道1112的长度与雾化器11吸阻的关系进行研究，并由此确定凸起1191的高度最佳数值。
研究结果如图30和图31所示，图30为计算得到的不同出气通道长度的吸阻随凸起高度的变化规律图，图31为不同凸起高度对应的出气口的温度分布图。
由图30可知，出气通道1112的吸阻随凸起1191高度、出气通道1112的长度的增大而增大；出气通道1112的长度越小，凸起1191高度可取的上限越大。例如，当出气通道1112的长度为20mm时，凸起1191高度可取0.6mm，甚至可取0.62mm；因此，优选凸起1191的高度的上限为0.6mm。其中，出气通道1112的长度在图30中用“L”表示。其中，实验条件：出气通道1112直径为3mm。
由图31可知，出气口1112a的气溶胶的最高温度在中心区域，在出气通道1112的长度相同的前提下，不设置凸起1191时，出气口1112a的气溶胶的最高温度为84.6℃；凸起1191的高度为0.1mm时，出气口1112a的气溶胶的最高温度为83.8℃，相比于不设置凸起1191，温度降低了0.9％；凸起1191的高度为0.2mm时，出气口1112a的气溶胶的最高温度为81.7℃，相比于不设置凸起1191，温度降低了3.4％；凸起1191的高度为0.3mm时，出气口1112a的气溶胶的最高温度为78.5℃，相比于不设置凸起1191，温度降低了7.2％；凸起1191的高度为0.4mm时，出气口1112a的气溶胶的最高温度为75.3℃，相比于不设置凸起1191，温度降低了11％；凸起1191的高度为0.5mm时，出气口1112a的气溶胶的最高温度为73.3℃，相比于不设置凸起1191，温度降低了13.4％。即，凸起1191的高度越高，出气口1112a的气溶胶的最高温度越低，降温效果越好；优选凸起1191的高度大于等于0.3mm。其中，实验条件：出气通道1112直径为3mm，气溶胶进出气通道1112的温度为100℃。
请参考图32，图32为凸起的截面为正方形的流场计算示意图。
参考图32，在一直径为1.5mm的圆管30中设置凸起31，沿着凸起31的高度方向，凸起31的截面为正方形，气体以2.6m/s的速度流过圆管30。其中，选用的气体的特性与气溶胶特性相似；气体的流速为出气通道1112中气溶胶的真实流速。凸起31的高度用“H”表 示，相邻的凸起31中心之间的距离用“P”表示。
取不同的凸起31高度，以图32的结构示意图进行实验，研究换热系数随相邻的凸起31中心之间的距离与凸起31的高度的比值(P/H)的变化规律。研究结果如图33所示，图33为正方形截面凸起的不同高度的换热系数变化规律图。由图33可知，不同凸起31高度H，换热系数的变化规律基本一致。因此，凸起31的高度H仅影响换热系数的数值，换热系数的变化规律主要受相邻的凸起31中心之间的距离与凸起31高度的比值(P/H)的影响。
以凸起31截面为正方形，凸起31高度H为0.2mm为例，对不同的P/H值对应的速度场分布继续进行研究，研究结果如图34和图35所示，图34为正方向截面凸起不同的P/H值对应的速度场分布图，图35为换热系数随正方向截面凸起不同的P/H值的变化规律图。
由图34可知，无论P/H值是多少，越远离壁面处的流速越快。从图可见，P/H数值过小，存在较大的低速区域；随着数值增大低速区域逐渐减小，等于17时刚好发生再附着，此时换热效果最好；继续增大数值后(P/H＝25)，低速区域减少，但是重新发展出新的层流边界层，影响换热效率。
可见，当P/H值过小时(例如，P/H为5)，相邻的凸起31之间间隔区域的流场未被充分干扰，换热效率提升效果微弱；当P/H值为17时，气流在相邻的凸起31之间的间距面上发生了再附着，再附着区域边界层厚度薄、换热效率高；当P/H数值过大时(例如，P/H为25)，气流发生再附着后重新发展出层流边界层，换热效率降低。因此，过小或过大的P/H值均不利于气溶胶与出气通道1112的壁面换热。
由图35可知，对于正方形截面的凸起31，相邻的凸起31中心之间的距离与凸起31高度的比值(P/H)为10-20时降温效果最好。因此，当设置于出气通道1112内壁面上的凸起1191的截面为正方形时，相邻的凸起1191中心之间的距离与凸起1191高度的比值为10-20，可选的，为13-17。
请参考图36，图36为凸起的截面为圆形的流场计算示意图。
参考图36，在一直径为1.5mm的圆管30中设置凸起31，沿着凸起31的高度方向，凸起31的截面为圆形，气体以2.6m/s的速度流过圆管30。其中，选用的气体的特性与气溶胶特性相似；气体的流速为出气通道1112中气溶胶的真实流速。凸起31的直径用“H”表示，相邻的凸起31中心之间的距离用“P”表示。由于凸起31的截面为圆形，凸起31的高度与凸起31的直径相同。
取不同的凸起31高度，以图36的结构示意图进行实验，研究换热系数随相邻的凸起31中心之间的距离与凸起31的高度的比值(P/H)的变化规律。研究结果如图37所示，图37为圆形截面凸起的不同高度的换热系数变化规律图。由图37可知，不同凸起31高度H，换热系数的变化规律基本一致。因此，凸起31的高度H仅影响换热系数的数值，换热系数的变化规律主要受相邻的凸起31中心之间的距离与凸起31高度的比值(P/H)的影响。
以凸起31截面为圆形，凸起31高度H为0.2mm为例，对不同的P/H值对应的速度场分布继续进行研究，研究结果如图38和图39所示，图38为圆形截面凸起不同的P/H值对应的速度场分布图，图39为换热系数随圆形截面凸起不同的P/H值的变化规律图。
由图38可知，无论P/H值是多少，越远离壁面处的流速越快。从图可见，P/H数值过小，存在较大的低速区域；随着数值增大低速区域逐渐减小，等于14时刚好发生再附着，此时换热效果最好；继续增大数值后(P/H＝20)，低速区域减少，但是重新发展出新的层流边界层，影响换热效率。
可见，当P/H值过小时，相邻的凸起31之间间隔区域的流场未被充分干扰，换热效率提升效果微弱；当P/H值为14时，气流在相邻的凸起31之间的间距面上发生了再附着，再附着区域边界层厚度薄、换热效率高；当P/H数值过大时，气流发生再附着后重新发展出层流边界层，换热效率降低。因此，过小或过大的P/H值均不利于气溶胶与出气通道1112的壁面换热。
由图39可知，对于圆形截面的凸起31，相邻的凸起31中心之间的距离与凸起31高度的比值(P/H)为7-20时降温效果最好。因此，当设置于出气通道1112内壁面上的凸起1191的截面为圆形时，相邻的凸起1191中心之间的距离与凸起1191高度的比值为7-20，可选的，为11-16。
因此，对于凸起1191的截面为正方形或圆形时，凸起1191的高度、相邻的凸起1191的中心之间的距离与凸起1191的高度的比值的最佳设计如表2所示。
表2
Figure PCTCN2022129351-appb-000002
也就是说，无论凸起1191的截面为正方形还是圆形，当出气通道1112的长度小于等于20mm时，凸起1191的高度为0.6mm-0.7mm；当出气通道1112的长度大于20mm且小于等于30mm时，凸起1191的高度为0.5mm-0.6mm；当出气通道1112的长度大于30mm且小于等于40mm时，凸起1191的高度为0.4mm-0.5mm；当出气通道的长度大于40mm且小于等于50mm时，凸起1191的高度为0.35mm-0.45mm；当出气通道的长度大于50mm时，凸起1191的高度为0.3mm-0.4mm。其中，当出气通道1112的长度小于20mm时，可选的，凸起1191的高度为0.6mm。当出气通道的长度大于40mm且小于50mm时，可选的，凸起1191的高度为0.4mm。
当凸起1191的截面为正方形，相邻的凸起1191的中心之间的距离与凸起1191的高度的比值为10-20。当凸起1191的截面为圆形，相邻的凸起1191中心之间的距离与凸起1191的高度的比值为7-20。可以理解，当凸起1191的截面为正方形或圆形，凸起1191的宽度与凸起1191的高度相同，对相邻的凸起1191中心之间的距离以及相邻的凸起1191中心之间的距离与凸起1191的高度的比值进行设计，也就考虑了凸起191的宽度对出气口1112a处气溶胶的温度的影响。
请参阅图40，图40为本申请提供的雾化器第三实施例的局部结构示意图。
在雾化器11第三实施例中，雾化器11的结构与雾化器11第一实施例的结构基本相同，不同之处在于：雾化器11的出气通道1112在远离雾化芯113的一端先分流成多个子出气通道1112b再次汇聚在一起。
用户在通过出气口1112a抽吸时，舌头位于或对应于出气口1112a的中心位置A，而舌头是感知温度的关键，通过降低出气口1112a的中心位置A的温度即可降低用户感知到的气溶胶的温度，进而提升用户的使用体验。本申请发明人研究发现，如果出气通道1112采用直通结构，出气口1112a中心位置A流出的气溶胶比周围流出的气溶胶的温度高(具体可参见图42的测试结果)。本申请通过使出气通道1112在远离雾化芯113的一端先分流成多个子出气通道1112b再次汇聚在一起的方式来降低出气口1112a的中心位置A的气溶胶温度。也就是说，雾化芯113雾化好的气溶胶在出气通道1112远离雾化芯113的一端先分流流入多个子出气通道1112b再汇聚在一起从出气口1112a流出，分流的过程中对气溶胶进行降温，相对于直通的出气通道1112，用户通过出气口1112a抽吸气溶胶时感知到的温度明显降低，利于提升用户的使用体验。其中，多个子出气通道1112b的个数可以根据需要进行设计。
在一实施方式中，在出气通道1112内设置隔板1112c，以将出气通道1112远离雾化芯113的一端分割成两个子出气通道1112b，以使出气通道1112先分流；其中，隔板1112c的延伸方向与出气通道1112的延伸方向相同。隔板1112c靠近出气口1112a的一端的端面与出气口1112a之间间隔设置，以使出气通道1112在分流后又汇聚在一起(如图40所示)。也就是说，出气通道1112包括第一部分、第二部分和第三部分，出气通道1112的入口即第一部分的入口，第三部分的出口即出气口1112a；第一部分和第三部分均为直通管，隔板1112c设置于第二部分，使得第二部分相对于第一部分和第三部分具有明显的分流效果，以实现分流降温。可以理解，多个子出气通道1112b的个数可以根据需要进行设计，隔板1112c的结构可以根据子出气通道1112b的个数进行设计。
其中，隔板1112c可以是与出气通道1112一体成型，也可以是与出气通道1112通过卡接等方式固定在一起，具体根据需要进行设计。隔板1112c的厚度根据需要进行设计，能够使出气通道1112远离雾化芯113的一端分割成两个子出气通道1112b，并能够对流经子出 气通道1112b的气溶胶降温即可。可以理解，气溶胶与子出气通道1112b内的空气进行混合降温，流经子出气通道1112b的气溶胶被子出气通道1112b的腔壁吸热，从而降低出气口1112a的气溶胶温度。进一步，由于两个子出气通道1112b内的气溶胶在出气口1112a的中心位置A汇聚混合，使得中心位置A流出的气溶胶的温度进一步被降低(具体可参见图44的测试结果)。
可选的，隔板1112c可以是实心板，即，两个子出气通道1112b的部分腔壁是共用的，此时隔板1112c厚度的设置需能够使两个子出气通道1112b内的气溶胶温度降低。
可选的，隔板1112c可以是空心板，即，隔板1112c的内部是中空的，两个子出气通道1112b为完全分离的两个通道；隔板1112c的壁厚及其内部中空空腔的宽度(隔板1112c内部中空空腔的宽度为沿着隔板1112c厚度方向的尺寸大小)决定着隔板1112c的厚度，隔板1112c的壁厚及其内部中空空腔的宽度根据需要进行设计，能够实现分流降温即可。可选的，隔板1112c为矩形空心板。
可选的，无论隔板1112c是矩形实心板还是矩形空心板，隔板1112c的长度(隔板1112c的长度为沿着出气通道1112延伸方向的尺寸)与出气通道1112的长度的比值为1:5-1:4。通过如上设置，可以实现较好的分流降温效果；在雾化器11的整体尺寸几乎不变的前提下，并不会使储液腔1111的存储空间减少太多，避免储液腔1111的存储量无法满足用户需求。
具体地，出气通道1112远离雾化芯113的一端在雾化器11宽度方向的尺寸变大形成加宽段B；加宽段B为出气通道1112的第二部分和第三部分。隔板1112c设置于加宽段B且平行于雾化器11的厚度方向，以将出气通道1112远离雾化芯113的一端分割成两个子出气通道1112b；隔板1112c靠近出气口1112a的端面与出气口1112a间隔设置，以使出气通道1112的第三部分为直通管，且两个子出气通道1112b中的气溶胶在第三部分汇聚在一起再从出气口1112a流出。通过在出气通道1112上设置加宽段B，设置于加宽段B的隔板1112c可以具有较大的厚度，能够更好的对两个子出气通道1112b中的气溶胶降温。在一实施方式中，加宽段B靠近雾化芯113的端面与隔板1112c靠近雾化芯113的端面齐平，即，设置有隔板1112c处才开始对出气通道1112的通道宽度进行加宽。
加宽段B可以是沿着其延伸方向的横截面形状、面积一致的；即，加宽段B为直通结构。加宽段B可以是包括第一段和第二段，第二段位于第一段远离雾化芯113的一侧；第一段沿着远离雾化芯113的方向的横截面积逐渐增大，使得第一段沿着远离雾化芯113的方向的纵截面为锥形结构；第二段沿着远离雾化芯113的方向的横截面积相同，即，第二段为直通结构(如图40所示)。通过将加宽段B的第一段设置为锥形结构，可以避免气溶胶在加宽段B的拐角处形成涡流，进而避免加宽段B的结构对气溶胶流出出气口1112a量的影响。
两个子出气通道1112b可以沿着隔板1112c对称设置，以使雾化芯113雾化好的气溶胶流经两个子出气通道1112b，气溶胶分别在两个子出气通道1112b可以实现相同的降温效果。
请参阅图41-图44，图41为现有的雾化器局部结构示意图，图42为图41提供的雾化器的出气口的气溶胶温度分布云图，图43为图40提供的雾化器的出气口的气溶胶温度分布云图，图44为图40提供的雾化器的出气通道靠近出气口一端的几面流速矢量分布图。
图41提供的雾化器的结构与图40提供的雾化器11的结构只有出气通道的设置方式不同，图41中的雾化器的出气通道为直通结构，对图41提供的现有雾化器进行测试，测试条件为：出气通道的直径为2.5mm，出气通道的长度为32.9mm，雾化芯上的S型发热层1134的初始温度为250℃，雾化量为3s/9mg。对图40提供的雾化器11进行测试，测试条件为：出气通道1112靠近雾化芯113的一端未分流前的直径为2.5mm，出气通道入口至出气口1112a之间的记录为32.9mm，雾化芯113上的S型发热层1134的初始温度为250℃，雾化量为3s/9mg。测试结果如图42-图44所示。
通过图44可以看出，气溶胶在出气通道1112中分流进入两个子出气通道1112b之后汇聚混合时在中心位置A会存在混合涡旋区，即在汇聚混合过程中会进一步使出气口1112a中心位置A的气溶胶温度降低，使得出气口1112a的最高温度位于中心位置A的两侧，利于降低用户感知到的气溶胶温度。
比较图42和图43，出气通道为直通结构时，气溶胶流经出气通道后直接流出，出气口的气溶胶混合较差，出气口的气溶胶温度相对集中在出气通道的中心位置，最高温度高达80℃；出气通道1112中设置有分流降温结构时，由于分流作用，气溶胶分别与两个子出气 通道1112b内的空气混合降温以及被两个子出气通道1112b的腔壁吸热，虽然气溶胶在出气口1112a又再次汇聚在一起，但中心位置A的温度明显降低，中心位置A的温度约为69℃，出气口1112a的最高温度位于中心位置A的两侧，且出气口1112a的最高温度也降低至约74℃，整体的降温效果约5℃-10℃。
经测试证明，出气通道1112在远离雾化芯113的一端先分流成多个子出气通道1112b再汇聚在一起，使得出气口1112a的气溶胶温度明显降低，提升了用户的使用体验。
下面对隔板1112c靠近出气口1112a的端面与出气口1112a之间间隔的间隔距离d进行研究。对具有分流结构的出气通道1112的雾化器11进行测试，测试条件为：出气通道1112靠近雾化芯113的一端未分流前的直径为2.5mm，出气通道入口至出气口1112a之间的记录为32.9mm，雾化芯113上的S型发热层1134的初始温度为250℃，雾化量为3s/9mg。测试结果如图45和图46所示，图45为出气口气溶胶最高温度与间隔距离d之间的关系曲线图，图46为出气口中心位置A的气溶胶温度与间隔距离d之间的关系曲线图。可以理解，图45中出气口1112a气溶胶最高温度指的是整个出气口1112a上的气溶胶最高温度。
对图45进行分析，可得出：隔板1112c靠近出气口1112a的端面与出气口1112a之间间隔的间隔距离d的大小对出气口1112a气溶胶最高温度影响不大。对图46进行分析，可得出：当隔板1112c靠近出气口1112a的端面与出气口1112a之间间隔的间隔距离d大于3mm后，出气口1112a的中心位置A处的气溶胶温度不再有比较大的变化，说明在间隔距离d等于3mm时，气溶胶的混合已经比较充分，继续增大间隔距离d对出气口1112a处的气溶胶温度分布的影响非常有限了。因此，优选d的范围为0mm＜d≤3mm，更优选d的范围为0mm＜d≤2.5mm。
其中，得出图46实验数据的雾化器11除了具有分流结构的出气通道1112，还设置了雾化芯113的雾化面与进气孔1125a之间的距离h为0.4mm。
可以理解，在通过使出气通道1112在远离雾化芯113的一端先分流成多个子出气通道1112b再汇聚在一起来降低出气口1112a的气溶胶的温度的前提下，雾化芯113的雾化面与进气孔1125a之间的距离h做如上设置(雾化器11第一实施例中具体介绍的内容：雾化芯113的雾化面与进气孔1125a之间的距离h)来降低出气口1112a的气溶胶温度为可选的，在出气通道1112中设置降温结构119(雾化器11第二实施例中具体介绍的降温结构119)来降低出气口1112a的气溶胶温度也为可选的。上述介绍的降低出气口1112a的气溶胶温度的三种实施方式，可以根据需要进行任意组合，能够使雾化器11的出气口1112a的气溶胶温度范围为55℃-85℃即可，可选的，使雾化器11的出气口1112a的气溶胶温度范围为70℃-80℃。
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。
