为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请的实施例，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，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。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
为解决现有技术中雾化气的冷凝情况较为严重的技术问题，本申请的一实施例提供一种应用于电子雾化装置的气帘形成结构。该气帘形成结构包括气流通道，气流通道用于传输雾化气。该气帘形成结构还包括第一进气通道，第一进气通道连通气流通道，第一进气通道用于将外部气流引入气流通道，以在气流通道的内壁和雾化气之间形成阻隔气流。以下进行详细阐述。
请参阅图1，图1是本申请雾化吸嘴第一实施例的结构示意图。
下文对气帘形成结构为应用于电子雾化装置的雾化吸嘴的一个示例性实施例进行阐述。
在本实施例中，气帘形成结构采用雾化吸嘴的形式。本实施例提供的雾化吸嘴可以应用于电子烟、医疗雾化器等电子雾化装置。具体地，雾化吸嘴包括气流通道11，气流通道11用于传输雾化气。雾化吸嘴还包括第一进气通道12，第一进气通道12连通气流通道11，第一进气通道12用于将外部气流引入气流通道11，以在气流通道11的内壁和雾化气之间形成阻隔气流。其中，阻隔气流形成气帘的形式。
进一步地，雾化吸嘴还包括连通气流通道11的出气口13，第一进气通道12靠近气流通道11的内壁，并且第一进气通道12的出口朝向出气口13，以保证经第一进气通道12进入气流通道11的气流能够沿气流通道11的内壁流动，即形成阻隔气流，能够阻隔雾化气和气 流通道11的内壁，使得雾化气尽可能少地接触气流通道11的内壁，能够缓解雾化气冷凝的情况，减少冷凝液的形成。
具体地，雾化吸嘴包括气道体21及吸嘴部。其中，吸嘴部包括管体22，气流通道11设于气道体21和管体22。管体22远离气道体21的一端为出气口13。第一进气通道12开设于气道体21靠近管体22的内壁的位置，以在管体22的内壁和雾化气之间形成阻隔气流。
气流通道11包括入口通道111和导气通道112。管体22具有导气通道112。气道体21安装于管体22的一端，气道体21具有入口通道111，气道体21的入口通道111与管体22的导气通道112连通。其中，入口通道111用于导入雾化气，并将雾化气输送至导气通道112中。
请参阅图1和图2，图2是本申请雾化吸嘴第一实施例的立体结构示意图。其中，气道体21安装于管体22的一端时，部分抵接于导气通道112的一端，并遮挡部分导气通道112。气道体21遮挡导气通道112的位置处设置有与导气通道112连通的第一进气通道12。可选地，气道体21具有抵接导气通道112的一端并遮挡部分导气通道112的壁部211，第一进气通道12位于壁部211上，并与导气通道112连通。
由于雾化气中含有水汽，容易在导气通道112的内壁形成冷凝液，设置第一进气通道12，第一进气通道12通入空气，在雾化吸嘴进行抽吸时，即在管体22远离气道体21的一端进行抽吸时，在雾化吸嘴内部形成气压差，在气压差的作用下，使得第一进气通道12中进入的空气附着在导气通道112的内壁，并在导气通道112的内壁形成阻隔气流，进而将雾化气与导气通道112的内壁隔离，以减少雾化气在导气通道112的内壁形成的冷凝液。在雾化吸嘴未进行抽吸时，雾化吸嘴内部没有气压差，导气通道112的内壁没有阻隔气流。
进一步地，阻隔气流的流动方向平行于气流通道11的内壁，即阻隔气流的流动方向平行于导气通道112的内壁，也就是阻隔气流的流动方向平行于管体22的内壁，以保证阻隔气流能够起到良好的阻隔雾化气和管体22的内壁的作用。
可选地，为了使导气通道112的内壁均附着有阻隔气流，以形成气帘形式，在一具体实施例中，第一进气通道12的数量可以为多个，且该多个第一进气通道12沿壁部211的周向彼此间隔排布。
请一并参阅图3，图3是本申请雾化吸嘴的气道体的第一进气通道的结构示意图。气道体21包括遮挡导气通道112的壁部211。第一进气通道12位于壁部211，且与导气通道112连通。如图3所示，第一进气通道12的数量为多个，其均匀的沿壁部211周向排布。在一具体实施例中，第一进气通道12的形状不做限定，其只要能够在抽吸时使空气进入导气通道112即可。在一可选实施例中，第一进气通道12的形状可以为方形、圆形、三角形中任意一种或任意组合。
进一步的，在设置第一进气通道12时，当对其大小进行合理规划时，可实现第一进气通道12中进入的空气能够在导气通道112的内壁形成完全覆盖导气通道112的内壁的阻隔气流。
请继续参阅图1，本申请的雾化吸嘴的气道体21包括第一气道部212、第二气道部213及连接第一气道部212与第二气道部213并遮挡部分导气通道112的壁部211。其中，入口通道111主要位于第一气道部212中，且与导气通道112连通，第二气道部213套设在吸嘴部的管体22的外侧。在一具体实施例中，壁部211抵接导气通道112的一端，在另一实施例中，壁部211还可以与导气通道112的一端具有间隙，其只要能够保证雾化气不会外泄即可。
可选地，请继续参阅图2，第一气道部212还包括通气部214及第一连接部215，其中，第一连接部215位于壁部211远离第二气道部213的一侧，通气部214位于第一连接部215远离壁部211的一侧。其中，第一连接部215的横截面面积(其中，横截面定义为垂直于轴向的截面，下同)小于通气部214的横截面面积，第一连接部215与通气部214连接的位置处形成卡接口216，卡接口216用于卡接雾化气产生装置(即电子雾化装置用于产生雾化气 的部分，图未示)。进一步地，请结合图1和图2，卡接口216的位置处形成有综合气道14，空气从综合气道14进入第一进气通道12，进而从第一进气通道12进入至导气通道112，在抽吸时，产生压力差后，在压力差的作用下在导气通道112的内壁形成阻隔气流。阻隔气流将雾化气与导气通道112隔离，进而减少雾化气在导气通道112形成的冷凝液。
可选地，在一实施方式中，气道体21中的第一气道部212、第二气道部213及连接第一气道部212及第二气道部213的壁部211一体成型。在另一实施方式中，气道体21中的第一气道部212、第二气道部213及连接第一气道部212及第二气道部213的壁部211还可以通过焊接等工艺连接而成。
可选地，气道体21的第二气道部213套设于吸嘴部的管体22的外侧。具体的，在一实施方式中，气道体21与管体22可以一体成型设计。在另一实施方式中，第二气道部213还可以通过匹配的方式套设于吸嘴部的管体22的外侧，为了防止雾化气外泄，在将第二气道部213套设于吸嘴部的管体22的外侧时可使用过盈配合的方式进行设置。
本实施例提供的雾化吸嘴，在遮挡导气通道112的壁部211设置与导气通道112连通的第一进气通道12，在管体22有抽吸动作时，雾化气从入口通道111进入导气通道112的同时，空气从第一进气通道12的位置处进入导体通道，在气压的作用下，从第一进气通道12进入的空气会在导气通道112的内壁形成阻隔气流，从而将雾化气与导气通道112的内壁隔离，进而防止雾化气在导气通道112的内壁形成冷凝液。
请参阅图4，图4是本申请雾化吸嘴第二实施例的结构示意图。与上述图1所示的第一实施例相比，区别在于：本实施例在通气部214的外侧设置有第二进气通道15。第二进气通道15用于加快雾化气的排出速度，以进一步防止雾化气在导气通道112的内壁形成冷凝液。
可选地，第二进气通道15包括进气部151及导气部152，具体地，进气部151在通气部214的周围沿平行于壁部211的方向设置，导气部152的延伸方向平行于入口通道111的延伸方向设置，且导气部152连接进气部151位于通气部214内的一端。其中，空气自进气部151中进入，并从导气部152流向导气通道112。
可选地，请参阅图4和图5，图5是本申请雾化吸嘴第二实施例的立体结构示意图。第二进气通道15位于通气部214，第一进气通道12位于连接第一气道部212及第二气道部213的壁部211。在一具体实施例中，当吸嘴部的管体22产生抽吸力时，雾化气从入口通道111进入，空气从第二进气通道15及第一进气通道12的位置进入。请结合图6，图6是本申请雾化吸嘴第二实施例的仰视结构示意图。如图6所示，第一进气通道12的位置较之第二进气通道15中的导气部152更靠近于管体22的内壁。因此，当进行抽吸时，在气压的作用下，第一进气通道12进入的空气在吸嘴部的管体22的导体通道的内壁形成阻隔气流，进而将从入口通道111进入的雾化气与导体通道的内壁隔离，以减少雾化气与导体通道的内壁形成的冷凝液。进一步的，设置第二进气通道15，在进行抽吸时，第二进气通道15进入空气，该空气加快自入口通道111进入的雾化气在导气通道112中的排出速度，进一步防止雾化气与导体通道的内壁形成冷凝液。
进一步地，请继续参阅图4和图5，第一连接部215与通气部214连接的位置处形成卡接口216，卡接口216用于卡接雾化气产生装置(图未示)。进一步地，卡接口216的位置处形成有综合气道14，空气从综合气道14进入第一进气通道12及第二进气通道15，进而从第一进气通道12进入至导气通道112，在抽吸时，产生压力差后，在压力差的作用下在导气通道112的内壁形成阻隔气流。如图4所示，阻隔气流(如图4中箭头Q1所示)将雾化气(如图4中箭头G所示)与导气通道112隔离，进而减少雾化气在导气通道112内壁形成冷凝液。空气从第二进气通道15进入导气部152，在进入导气通道112形成第二气流，第二气流加快雾化气的排出速度。
可选地，在本实施例中，第二进气通道15的导气部152可以为方形、圆形、三角形中任意一种或任意组合。第二进气通道15的进气部151同样可以为方形、圆形、三角形中任意一 种或任意组合，具体不做限定，其只要能够将空气引入导气部152，进而进入导气通道112中即可。
在一实施例中，第二进气通道15为至少一个，且其在通气部214的外侧周向排布。
在一实施例中，第二进气通道15可以与第一进气通道12的位置对应设置，在另一实施例中，第二进气通道15还可以与第一进气通道12的位置错开设置。具体的，为了减少进入第一进气通道12及第二进气通道15的空气形成的气流之间的相互影响，第二进气通道15与第一进气通道12的位置错开设置，如图6所示。
在一实施例中，在设置第一进气通道12及第二进气通道15时，为保证第一进气通道12进入的空气在导气通道112的内壁形成阻隔气流，进而实现将雾化气与导气通道112隔离，并实现自第二进气通道15进入的空气能够加快雾化气的排出速度，第二进气通道15及第一进气通道12形成的气流具有速度差。在一具体实施例中，第一进气通道12形成的气流的流速要大于第二进气通道15形成的气流的流速，以此能在实现减少冷凝液的效果的同时，减少对雾化气的传输方向的影响。
具体的，第一进气通道12及第二进气通道15形成的气流的流速与开孔的尺寸相关，开孔的尺寸越大，流速越快。因此，在一具体实施方式中，为实现第一进气通道12形成的气流的流速要大于第二进气通道15形成的气流的流速，设置第一进气通道12的尺寸(即横截面面积，其中第一进气通道12的横截面应当是沿垂直于第一进气通道12的延伸方向截取的截面)大于第二进气通道15的尺寸(即横截面面积，其中第二进气通道15的横截面应当是沿垂直于第二进气通道15的延伸方向截取的截面)，或者在另一实施例中，设置第一进气通道12的数量大于第二进气通道15的数量。
如图4所示，在用户进行抽吸而产生气压差时，在气压差的作用下，外部气流经第一进气通道12进入气流通道11(即导气通道112)，在气流通道11的内壁形成阻隔气流Q1。阻隔气流Q1将雾化气G与气流通道11的内壁隔离，以减少雾化气G在气流通道11的内壁形成的冷凝液。另外，在气压差的作用下，经第二进气通道15进入气流通道11的气流Q2沿雾化气G的外边沿进行流动，以加快雾化气G的排出速度。

下文对气帘形成结构为应用于电子雾化装置的雾化吸嘴的一个示例性实施例进行阐述。

进一步地，第一导流部31和气流通道11的内壁之间可以形成多个第一进气通道12，经该多个第一进气通道12形成的阻隔气流形成气帘的形式，如图8所示，极大程度地使得雾化气尽可能少地接触雾化吸嘴的内壁(即气流通道11的内壁)，能够缓解雾化气冷凝的情况，减少冷凝液的形成。
可选地，第一导流部31可以为对应雾化吸嘴内部空间的环状，其沿雾化吸嘴的周向环绕。
在一实施例中，请继续参阅图8，雾化吸嘴还包括第二导流部33。第二导流部33相对第一导流部31远离气流通道11的内壁，并且第二导流部33和第一导流部31之间形成第二进气通道15，第二进气通道15的出口朝向出气口13，经第二进气通道15进入的气流(如图8中箭头Q2所示)用于引导雾化气从出气口13输出，从而加快雾化气的排出。
进一步地，第二导流部33呈环状设置，以包围形成雾化吸嘴的第一进气口16。

在本实施例中，请参阅图10，气帘形成结构包括雾化吸嘴、雾化芯40以及储液腔50。雾化吸嘴设有第一进气口16和出气口13，雾化气自第一进气口16进入雾化吸嘴，并通过雾化吸嘴传输至出气口13，进而从出气口13输出，以供用户吸食。雾化芯40设于雾化吸嘴的第一进气口16的所在位置处，用于雾化储液腔50中所存储的气溶胶生成基质而产生雾化气。其中，雾化芯40以及储液腔50等结构组成本实施例气帘形成结构的雾化气产生装置，用于产生雾化气。
针对本实施例气帘形成结构应用于医疗雾化器的情况，雾化芯40可以是超声波雾化片等，超声波雾化片利用高频的震荡使得气溶胶生成基质雾化而产生雾化气，其具体原理属于本领域技术人员的理解范畴，在此就不再赘述。当然，针对气帘形成结构应用于其它领域的情况，雾化芯40也可以采用加热雾化气溶胶生成基质等产生雾化气的方式，在此不做限定。
具体地，请一并参阅图11，雾化吸嘴包括气流通道11，气流通道11用于传输雾化气。雾化吸嘴还包括第一进气通道12，第一进气通道12连通气流通道11，第一进气通道12用于将外部气流引入气流通道11，以在气流通道11的内壁和雾化气之间形成阻隔气流(如图11中箭头Q1所示，下同)。其中，阻隔气流形成气帘的形式。
进一步地，第一进气口16和出气口13相对设置且二者分别连通气流通道11。第一进气通道12靠近气流通道11的内壁，并且第一进气通道12的出口朝向出气口13，以保证经第一进气通道12进入气流通道11的气流能够沿气流通道11的内壁(即雾化吸嘴的内壁)流动，即形成阻隔气流，能够阻隔雾化气和气流通道11的内壁，即阻隔雾化气和雾化吸嘴的内壁，使得雾化气尽可能少地接触雾化吸嘴的内壁，能够缓解雾化气冷凝的情况，减少冷凝液的形成。
进一步地，阻隔气流的流动方向平行于气流通道11的内壁，即阻隔气流的流动方向平行于雾化吸嘴的内壁，以保证阻隔气流能够起到良好的阻隔雾化气和雾化吸嘴的内壁的作用。
在一实施例中，请继续参阅图11，雾化吸嘴还包括第一导流部31。第一导流部31和气流通道11的内壁之间形成有第一进气通道12，用于引导通过第一进气通道12引入的气流沿气流通道11的内壁流动，以形成阻隔气流。

具体地，第一导流部31和气流通道11的内壁之间设有多个第二连接部32。该多个第二连接部32沿第一导流部31的周向依次间隔设置，相邻的第二连接部32之间形成第一进气通道12，即形成至少一个第一进气通道12。如此一来，实现了第一导流部31在雾化吸嘴中相对位置的固定，同时也保证了第一导流部31和气流通道11的内壁之间的第一进气通道12的形成。
可选地，第一导流部31可以为对应雾化吸嘴内部空间的环状，其沿雾化吸嘴的周向环绕。
在一实施例中，请继续参阅图11，雾化吸嘴还包括第二导流部33。第二导流部33相对第一导流部31远离气流通道11的内壁，并且第二导流部33和第一导流部31之间形成第二进气通道15，第二进气通道15的出口朝向出气口13，经第二进气通道15进入的气流用于引导雾化气从出气口13输出，从而加快雾化气的排出。
进一步地，第二导流部33呈环状设置，以包围形成雾化吸嘴的第一进气口16。
进一步地，气帘形成结构还包括第三连接部34，第二导流部33和第一导流部31之间通过第三连接部34连接，从而通过第一导流部31固定第二导流部33在雾化吸嘴中的相对位置。

在一实施例中，请继续参阅图11，气帘形成结构还包括汇流通道17，汇流通道17的一端为进气口，即第二进气口18，另一端为分流口171，分流口171分别连通第一进气通道12和第二进气通道15。

图11展示了第一通道段172的延伸方向为水平方向，第二通道段173的延伸方向为竖直方向，并且第二通道段173朝向出气口13延伸。当用户抽吸时，外部的气流自第二进气口18进入第二通道段173，并传输至第一通道段172，进而通过分流口171分别经第一进气通道12和第二进气通道15进入雾化吸嘴中的气流通道11，其中气流流动情况如图11中虚线箭头所示。
进一步地，气帘形成结构设有安装部60。安装部60设有安装凸起61和通风凹槽62，安装凸起61用于固定雾化吸嘴。在雾化吸嘴固定于安装部60后，雾化吸嘴和安装部60之间形成第一通道段172，具体是雾化吸嘴和安装部60的底部之间形成第一通道段172；并且通风凹槽62和雾化吸嘴之间形成第二通道段173。
在一实施例中，请继续参阅图11，雾化吸嘴的外周设有沿其周向环绕的限位槽35，限位槽35用于放置弹性圈，以固定雾化吸嘴。具体地，在雾化吸嘴嵌入于上文所述的安装部60后，限位槽35中放置的弹性圈与安装部60中的安装凸起61弹性过盈配合，从而将雾化吸嘴固定于安装部60中。
需要说明的是，安装部60中通风凹槽62所在位置处的弹性圈不会堵塞雾化吸嘴和通风凹槽62之间的间隙，以保证雾化吸嘴和通风凹槽62之间的通风功能，进而保证外部气流能够进入气流通道11，以形成阻隔气流以及加快雾化气的排出。
可选地，限位槽35的数量可以是多个，该多个限位槽35沿雾化吸嘴的轴向彼此间隔设置。通过多个限位槽35的设计，能够保证雾化吸嘴和安装部60之间具有足够的结合强度，以避免雾化吸嘴脱落。并且，弹性圈可以是硅胶圈等，在此不做限定。
请参阅图12，图12是本申请雾化器第一实施例的局部剖面结构另一视角的示意图。以下对本示例性实施例中第一进气通道12和第二进气通道15的气流情况进行阐述。
一方面，第一进气通道12的横截面面积会影响阻隔气流的气流量。具体地，在用户抽吸所引起的气压差一定的情况下，在一定范围内，第一进气通道12的横截面面积越大，阻隔气流的气流量就会越大。具体表现为第一导流部31和雾化吸嘴的内壁(即气流通道11的内壁)之间的距离D越大，第一进气通道12的横截面面积越大，阻隔气流的气流量也越大。
可以理解的是，由于用户抽吸所引起的气压差有限，因此阻隔气流的气流量是存在上限的，当阻隔气流的气流量达到上限时，即便继续增大第一导流部31和雾化吸嘴的内壁的距离，阻隔气流的气流量也不会具有明显的涨幅。
另一方面，经第二进气通道15进入气流通道11(即雾化吸嘴)的气流(如图12中箭头Q2所示，下同)的流向将会影响气流通道11内部的气流情况。具体地，经第二进气通道15进入的气流的流向与预设方向的夹角(如图12中角θ所示，下同)过小时，经第二进气通道15进入的气流会受阻隔气流的影响而被阻隔气流吸引，致使经第二进气通道15进入的气流无法很好地携带雾化气输出，其加快雾化气排出的效果将会大打折扣；而经第二进气通道15进入的气流的流向与预设方向的夹角过大时，经第二进气通道15进入的气流会对雾化气的输出路径形成阻挡，阻碍雾化气传输至雾化吸嘴的出气口13。其中，预设方向平行于阻隔气流(如图12中箭头Q1所示)的流向，即预设方向可以利用阻隔气流的流向来表示。
有鉴于此，经第二进气通道15进入的气流的流向与预设方向的夹角优选为30°至45°，例如30°、33°、37°、41°、43°、45°等。如此一来，能够保证经第二进气通道15进入的气流携带雾化气输出以加快雾化气排出的功能实现。
需要说明的是，可以通过调整第二进气通道15所在位置处的雾化吸嘴的结构来调整经第二进气通道15进入的气流的流向。举例而言，可以通过调整第一导流部31和第二导流部33在气流通道11轴向上的位置来调整经第二进气通道15进入的气流的流向，在此不做限定。

下文对气帘形成结构为应用于电子雾化装置的雾化器的一个示例性实施例进行阐述。
在本实施例中，气帘形成结构采用雾化器的形式。本实施例提供的雾化器可以应用于电子烟、医疗雾化器等电子雾化装置。图16展示了气帘形成结构应用于医疗雾化器的情况，仅为论述需要，并非因此对本实施例气帘形成结构的应用环境造成限定。

针对本实施例气帘形成结构应用于医疗雾化器的情况，雾化芯40可以是超声波雾化片等，超声波雾化片利用高频的震荡使得气溶胶生成基质雾化而产生雾化气，其具体原理属于本领域技术人员的理解范畴，在此就不再赘述。当然，针对气帘形成结构应用于其它领域的情况，雾化芯40也可以采用加热雾化气溶胶生成基质等产生雾化气的方式，在此不做限定。
具体地，请参阅图17，雾化吸嘴包括气流通道11，气流通道11用于传输雾化气。雾化吸嘴还包括第一进气通道12，第一进气通道12连通气流通道11，第一进气通道12用于将外部气流引入气流通道11，以在气流通道11的内壁和雾化气之间形成阻隔气流(如图17中箭头Q1所示，下同)。其中，阻隔气流形成气帘的形式。
进一步地，第一进气口16和出气口13相对设置且二者分别连通气流通道11。第一进气通道12靠近气流通道11的内壁，并且第一进气通道12的出口朝向出气口13，以保证经第一进气通道12进入气流通道11的气流能够沿气流通道11的内壁(即雾化吸嘴的内壁)流动，即形成阻隔气流，能够阻隔雾化气和气流通道11的内壁，即阻隔雾化气和雾化吸嘴的内壁，使得雾化气尽可能少地接触雾化吸嘴的内壁，能够缓解雾化气冷凝的情况，减少冷凝液的形成。
进一步地，阻隔气流的流动方向平行于气流通道11的内壁，即阻隔气流的流动方向平行于雾化吸嘴的内壁，以保证阻隔气流能够起到良好的阻隔雾化气和雾化吸嘴的内壁的作用。

也就是说，导流件用于引导气流流向雾化芯40，从而带动雾化芯40附近的雾化气从出气口13输出，能够有效缓解雾化芯40附近的雾化气滞留的情况，进而缓解雾化芯40附近的雾化气冷凝的情况。
具体地，导流件的至少部分沿远离雾化吸嘴的内壁和出气口13的方向倾斜设置，用于引导自第二进气口18进入的气流朝向第一进气口16流动，即引导气流朝向雾化芯40流动，其直冲雾化芯40表面，以携带经雾化芯40雾化形成的雾化气自第一进气口16进入雾化吸嘴并从出气口13输出，加快雾化气的排出，能够从一定程度上减少雾化气接触雾化吸嘴的内壁，进而缓解雾化气冷凝的情况，减少冷凝液的形成。
在一实施例中，请继续参阅图17，导流件包括第一导流部31。第一导流部31和气流通道11的内壁(即雾化吸嘴的内壁)之间形成有第一进气通道12，用于引导通过第一进气通道12引入的气流沿气流通道11的内壁流动，其中经第一进气通道12进入的气流用于在雾化吸嘴的内壁和雾化气之间形成阻隔气流。

在一实施例中，请继续参阅图17，导流件还包括第二导流部33。第二导流部33设于第一导流部31远离出气口13的一侧，即第一导流部31相对第二导流部33靠近出气口13。第二导流部33沿远离气流通道11的内壁和出气口13的方向倾斜设置，用于形成第二进气通道15，经第二进气通道15进入的气流用于引导雾化气从出气口13输出，进而加快雾化气的排出。
具体地，经第二进气通道15进入的气流沿第二导流部33流动至第一进气口16，以与第一进气口16处的雾化气混合，进而携带雾化气通过第一进气口16并从出气口13输出。
可选地，第二导流部33可以为对应雾化吸嘴内部空间的环状，其沿雾化吸嘴的周向环绕。
在一实施例中，请继续参阅图17，气帘形成结构还包括汇流通道17，汇流通道17的一端为进气口，即第二进气口18，另一端为分流口171，分流口171分别连通第一进气通道12和第二进气通道15。
具体地，汇流通道17包括连通的第一通道段172和第二通道段173，第一通道段172远离第二通道段173的端口为分流口171，第二通道段173远离第一通道段172的端口为进气口，即第二进气口18。其中，第一通道段172和第二通道段173的延伸方向不同。
图17展示了第一通道段172的延伸方向为水平方向，第二通道段173的延伸方向为竖直方向，并且第二通道段173朝向出气口13延伸。当用户抽吸时，外部的气流自第二进气口18进入第二通道段173，并传输至第一通道段172，进而通过分流口171分别经第一进气通道12和第二进气通道15进入雾化吸嘴中的气流通道11，其中气流流动的情况如图17中虚线箭头所示。
进一步地，气帘形成结构设有安装部60。安装部60设有安装凸起61和通风凹槽62，安装凸起61用于固定雾化吸嘴。在雾化吸嘴固定于安装部60后，雾化吸嘴和安装部60之间形成第一通道段172，具体是雾化吸嘴和安装部60的底部之间形成第一通道段172；并且通风凹槽62和雾化吸嘴之间形成第二通道段173。
请参阅图18，图18是本申请雾化器分流口的中心线与第一导流部和第二导流部的连接处的相对位置关系的结构示意图。以下对本示例性实施例中第一进气通道12和第二进气通道15的气流情况进行阐述。
本示例性实施例中经第一进气通道12进入的气流在雾化吸嘴的内壁和雾化气之间形成阻隔气流，使得雾化气尽可能少地接触雾化吸嘴的内壁，能够缓解雾化气冷凝的情况，减少冷凝液的形成；而经第二进气通道15进入的气流引导雾化气从出气口13输出，以加快雾化气排出，从而有效缓解导流件所包围形成的腔体中雾化气冷凝的情况。
由于用户抽吸而引起的气压差一定，因此进入第一进气通道12和第二进气通道15的气流总量一定，因此本示例性实施例通过合理分配进入第一进气通道12和第二进气通道15的气流量，来缓解雾化吸嘴内壁的雾化气冷凝的情况以及导流件所包围形成的腔体中雾化气冷凝的情况。
在一实施例中，分流口171的中心线α(分流口171的中心线α定义为垂直于分流口171的中轴线，下同)过第一导流部31和第二导流部33的连接处，如图18a所示。如此一来，经第一进气通道12进入的气流足以在雾化吸嘴的内壁和雾化气之间形成阻隔气流，减小雾化吸嘴的内壁上雾化气粘附的程度，并且经第二进气通道15进入的气流足以快速地携带雾化气 排出，能够减小导流件所包围形成的腔体中雾化气粘附的程度。
在一替代实施例中，分流口171的中心线α相对第一导流部31和第二导流部33的连接处远离出气口13，如图18b所示。如此一来，经第二进气通道15进入的气流的气流量显著增加，能够进一步加快携带雾化气排出，进一步减小导流件所包围形成的腔体中雾化气粘附的程度，缓解导流件所包围形成的腔体中雾化气冷凝的情况。
在另一替代实施例中，分流口171的中心线α相对第一导流部31和第二导流部33的连接处靠近出气口13，如图18c所示。如此一来，经第一进气通道12进入的气流的气流量显著增加，能够进一步增加雾化吸嘴的内壁和雾化气之间的阻隔气流的气流量，进一步减小雾化吸嘴的内壁上雾化气粘附的程度，缓解雾化吸嘴内壁的雾化气冷凝的情况。
需要说明的是，第一进气通道12和第二进气通道15的横截面面积的大小关系与第一进气通道12和第二进气通道15的气流量的大小关系相同。也就是说，第一进气通道12的横截面面积大于第二进气通道15的横截面面积，则第一进气通道12的气流量大于第二进气通道15的气流量，反之则反。
有鉴于此，本示例性实施例中还可以通过调整导流件的第二导流部33的倾斜程度，来调整第二进气通道15的横截面面积，进而调整第一进气通道12和第二进气通道15的横截面面积的大小情况，达到调整第一进气通道12和第二进气通道15的气流量的目的。
具体地，第二导流部33越朝向远离出气口13的方向倾斜，第二进气通道15的横截面面积越小，第二进气通道15的气流量越小，而第一进气通道12的气流量越大，反之则反。
需要说明的是，通过上述方式，雾化吸嘴的内壁上雾化气的粘附率以及导流件所包围形成的腔体中雾化气的粘附率低于3％。可见，本示例性实施例第一进气通道12和第二进气通道15的设计，能够有效减小雾化气的粘附程度，缓解雾化气冷凝的情况。

可选地，窄缝形式的第一进气通道12的宽度可以为0.3mm、0.4mm等，在此不做限定。
需要说明的是，窄缝形式的第一进气通道12所形成阻隔气流的分布情况优于通孔形式的第一进气通道12所形成阻隔气流的分布情况，并且宽度为0.4mm的窄缝形式的第一进气通道12所形成阻隔气流的分布情况优于宽度为0.3mm的窄缝形式的第一进气通道12所形成阻隔气流的分布情况。并且，由于阻隔气流的存在，雾化腔71内部气流的整体流向更加有序，不易形成涡流。
请参阅图22，图22是本申请雾化器第四实施例的结构示意图。
