技术领域
本申请属于电子雾化技术领域，尤其涉及一种雾化芯、雾化器及电子雾化装置。
 背景技术
相关技术的雾化器，在正常的情况下，雾化腔内存储的雾化液，通过下油通道输送至整体雾化芯的导油体，然后通过发热体将导油体上的油液加热雾化形成可供吸食的气溶胶。
但是由于有一些雾化液的粘稠性较大，其流动性差，使得雾化器中的雾化液无法从雾化芯的顶部导流至雾化芯底壁，导致雾化芯无法整体被雾化液浸润。因此，当雾化器启动时，雾化芯局部无雾化液进行雾化，出现局部高温，从而发生干烧、糊味等问题，影响用户体验。
 技术问题
本申请所要解决的技术问题在于提供一种雾化芯、雾化器及电子雾化装置，能够使雾化芯被雾化液浸润更加充分，雾化芯工作时不容易发生局部干烧而导致糊味，用户体验更佳。
 技术解决方案
本申请的第一方面提供一种雾化芯，包括：
硬质导油体，顶部为吸液面，与所述吸液面邻接的一侧凹陷形成有雾化槽，所述雾化槽的槽壁界定形成雾化腔，所述硬质导油体背离所述雾化槽的一侧设置有相接于所述吸液面且朝底部延伸的导液结构；以及，
发热体，安置于所述雾化槽内并且和所述导液结构对应的侧壁的至少部分接触连接。
本申请的第二方面提供一种雾化器，包括具有储液腔的油杯和装配于所述油杯的雾化组件，所述油杯具有出气通道，所述雾化组件包括如上所述的雾化芯，所述雾化组件形成有连通所述储液腔且相接于所述硬质导油体的吸液面的导油通道以及一端连通外界大气且另一端连通所述出气通道的雾化气道，所述雾化腔为所述雾化气道的一部分。
本申请的第三方面提供一种电子雾化装置，包括电池杆和装配于所述电池杆内的如上所述的雾化器。
 有益效果
在本方案中，雾化液可以通过导液结构从发热体的背离雾化槽的一侧自上而下传导，从而使雾化液从背离雾化槽的一侧朝硬质导油体内部渗透，因此，雾化液一方面可以从顶部到底部传导向雾化槽内壁，另一方面可以从背部传导向雾化槽的内壁，使得雾化液可以顺畅地流向硬质导油体的底部，使硬质导油体被雾化液浸润更加充分，而发热体安置于雾化槽内且和导液结构对应的侧壁接触连接，如此，发热体所在区域的硬质导油体储液量更高更均匀，雾化芯工作时不容易发生局部干烧而导致糊味，用户体验更佳。

在本申请中，结合图1-5，提供一种电子雾化装置，包括电池杆200和装配于电池杆200内的雾化器100，雾化器100包括具有储液腔20的油杯3和装配于油杯3的雾化组件4，电池杆200开设有和储液腔20位置对应的视窗210，油杯3具有出气通道311，雾化组件4包括雾化芯。储液腔20用于存储雾化液以供给雾化组件4，电池杆200用于给雾化组件4供电从而使雾化液被加热雾化形成气溶胶，电池杆200上的视窗210可以方便用户直观地判断储液腔20内的雾化液储量，体验更佳。
其中，结合图9、12-15，雾化芯包括硬质导油体1和发热体2，硬质导油体1的一侧凹陷形成有雾化槽10，雾化槽10的槽壁界定形成雾化腔；发热体2安置于雾化槽10内并且发热体2和雾化槽10的槽壁的至少部分接触连接。
在本方案中，雾化槽10位于硬质导油体1的一侧，发热体2安置于雾化槽10内，由于雾化槽10的槽口显露于外部，发热体2更容易从雾化槽10的槽口方向实现与硬质导油体1的装配，且装配完成后的雾化芯不会发生浆料从硬质导油体1脱落的问题，此外，在雾化芯的生产制造和测试过程中，可以从雾化槽10的槽口观察或测量发热体2的相关参数，例如发热体2的线径、线距等，解决了以往市面上圆柱形陶瓷发热体2只能测试组装，无法检测识别在烧制过程线距的变化、发热体2氧化的情况等的问题，从而保证发热体2和硬质导油体1装配后的可靠性，从而提升采用了本方案的雾化芯的雾化器100的性能。
在本实施例中，硬质导油体1采用陶瓷材料，尤其是多孔陶瓷材料，其具有良好的吸油和锁油功能。在一些实施例中，硬质导油体1也可以采用玻璃纤维体等内部具有孔隙结构的材料。
进一步地，硬质导油体1包括主体11、以及连接于主体11且相对设置的两侧壁12，其中，雾化槽10由主体11和两侧壁12围合形成，发热体2接触连接于主体11。由于发热体2设置于雾化槽10内且接触连接于主体11，侧壁12可以阻挡发热体2发出的热量朝两侧传导，发热体2所发出的热量可以更加集中地用于雾化油的雾化，从而提高热能的利用率。
具体的，在本方案中，两侧壁12连接于主体11的同一侧，两侧壁12的长度延伸方向相互平行，即硬质导油体1的横截面整体呈U形，主体11的周侧角部位置可以倒圆角或者切角，侧壁12的周侧角部位置也可以倒圆角或者切角，侧壁12和主体11的外侧相连处可以为光滑过渡，因此，可以使得雾化芯的整体性更好，一方面雾化芯的角部位置不容易磕碰受损，另一方面在加工雾化芯的过程中硬质导油体1更容易实现定位摆放，便于加工组装。
进一步地，在所述主体11朝向所述雾化槽10的方向上所述侧壁12的厚度小于所述主体11的厚度；和/或，在高度方向上所述侧壁12的厚度小于所述主体11的厚度。
为了提高硬质导油体1的结构强度，使其不易破损断裂，定义主体11朝向雾化槽10的方向为第一方向，在第一方向上，侧壁12的厚度小于主体11的厚度。具体的，在本方案中，两侧壁12在第一方向上的厚度相等，因此，雾化槽10远离主体11的开口的侧边到主体11的距离相等，可以理解的，雾化槽10的深度等于侧壁12在第一方向上的厚度，即雾化槽10的深度小于主体11的厚度。在一些实施例中，两侧壁12在第一方向上的厚度也可以不相等。
定义侧壁12朝向雾化槽10的方向为第二方向，侧壁12在第二方向上的厚度小于主体11在第一方向上的厚度。具体的，第一方向垂直于第二方向，由于两侧壁12在第二方向上的厚度相等，在本方案中，第二方向也是进油方向，即雾化油从侧壁12的外侧朝雾化槽10的方向逐步传导，两侧壁12在第二方向上的厚度相等可以使得硬质导油体1从两侧进油的量更加均匀。在一些实施例中，两侧壁12在第二方向上的厚度也可以不相等，一般理解，厚度越大时传导路径越长，导油速度越慢，两侧壁12的具体厚度可以根据实际需要的导油速度适应性调整。在一些实施例中，侧壁12在第二方向上的厚度也可以大于或等于主体11在第一方向上的厚度，这样可以使得雾化腔的体积更大，从而提升气溶胶容纳量。
进一步地，雾化槽10贯穿硬质导油体1的两端，雾化槽10的横截面为C形、U形、折线形中的一种。在本实施例中，雾化槽10的横截面为折线形，为优选的，雾化槽10的横截面为[型，雾化槽10在长度方向上各处的横截面均相同，即雾化槽10的槽壁所界定的雾化腔为横截面为矩形的空腔，由于雾化槽10的两端为开口状，气流可以从雾化槽10雾化腔的一端进入，然后从雾化腔的另一端流出，且气流流速均匀。
在一些实施例中，雾化槽10也可以不贯穿硬质导油体1的端部，或者，雾化槽10仅贯穿硬质导油体1的一端，如此，进气气流和出气气流中，至少一路气流可以从雾化槽10的远离主体11的开口处通过。
在一些实施例中，雾化槽10的横截面为折线形的情况下，折线形可以包括两条、四条、五条或六条等依次相连的折边，且折线形优选为对称结构。
在一些实施例中，雾化槽10的横截面也可以是C形、U形等。
在一些实施例中，雾化槽10在长度方向上各处的横截面可以不同，例如在横截面形状相同的情况下，雾化槽10靠近中部处的横截面尺寸小于靠近端部处的横截面的尺寸，因此，气流在雾化腔的中部位置处流速更大，可以带动发热体2中部形成的气溶胶快速流走，从而提升气溶胶生成速率。应当理解，雾化槽10在长度方向上各处的横截面形状和尺寸可以根据实际需要进行适应性调整，在此不作限定。
进一步地，结合图8-11，发热体2包括贴合连接于主体11的靠近雾化槽10的一侧的发热部21以及连接于发热部21的两端的电极部22，电极部22连接于侧壁12。
在本实施例中，发热部21具有位于中部的第一发热区和位于第一发热区相对的两侧的第二发热区，其中，第二发热区的单位面积发热效率高于第一发热区，两第二发热区和两侧壁12一一对应，第二发热区靠近对应的侧壁12。优选的，发热部21采用多个菱形结构依次相连的形式，其中，各菱形结构的短轴端依次相连，菱形结构的长轴端分别朝向两个侧壁12，因此，当雾化油从两侧壁12流向主体11中部的过程中，发热部21可以及时将雾化油雾化，以提高雾化效果。
在一些实施例中，发热体2可以采用蚀刻、冲压等加工方式形成，并且发热部21的形状可以包括但不限于S形、网状、折线形、矩形、方形等等。
进一步地，侧壁12的背离雾化槽10的一侧凹陷形成有收容空间121，两电极部22分别连接于两侧壁12，电极部22贯穿对应的侧壁12且收容于对应的收容空间121内。优选的，发热部21贴合连接于主体11的靠近雾化槽10的一侧，发热部21长度方向的两端均设置有一个电极部22，其中一个电极部22朝一个侧壁12弯折延伸并贯穿该侧壁12，另一个电极部22朝另一个侧壁12弯折延伸并贯穿该侧壁12，此时，两电极部22位于硬质导油体1长度方向的不同位置处，如此设置，发热部21可以压紧贴合在主体11上，保证发热体2和硬质导油体1的紧密配合，提高连接强度，防止发热部21翘起。
在一个实施例中，电极部22也可以设置在发热部21的宽度方向上的两端，此时，两电极部22位于硬质导油体1长度方向的相同位置处。
在一些实施例中，结合图12-15，两电极部22可以均贯穿至同一侧壁12的外侧。具体的，发热部21长度方向的两端均设置有一个电极部22，两个电极部22朝同一个侧壁12弯折延伸并贯穿该侧壁12，两个电极部22外露于该侧壁12的外侧，如此设置，在电连接发热体2时，仅需在一侧连接即可，工位变化更少，工艺成本更低。
进一步地，如图8和11，收容空间121延伸至侧壁12的一端，发热体2还包括连接于电极部22的引脚23，引脚23的和电极部22相连的一端收容于收容空间121内，引脚23的另一端突出于侧壁12的端部。优选的，收容空间121可以是位于侧壁12的外侧的收容槽，并且，两侧壁12上的收容槽朝硬质导油体1的同一端延伸，如此设置，两引脚23可以分别收容于对应侧壁12的收容槽内并从硬质导油体1的同一端引出，而且，两引脚23分别设置在不同的侧壁12外，可以防止相互干涉，降低供电引脚23的布线难度。收容槽可以设置于侧壁12的靠近端部的位置，因此，可以尽量减小收容槽的占用空间，以保证侧壁12的结构强度。
如果将引脚23外露高出侧壁12的外表面，整个雾化芯的外表面会凸凹不平影响导油效果和装配精度，如果完全埋在硬质导油体1内，会使得硬质导油体1的结构强度变低，且受力后可能导致其表面覆盖的陶瓷掉粉，影响安全和抽吸口感。因此，本申请通过设置收容引脚23的收容空间121，避免引脚23凸起侧壁12外表面导致不好装配，另外，当导油棉413是包在侧壁12外表面时，棉包裹更平整且导油均匀，能避免引脚23凸起引起的下油过快（漏油）/过慢（干烧糊味）等问题。
在一些实施例中，两侧壁12上的收容槽可以朝硬质导油体1的不同端延伸。
在一些实施例中，收容槽也可以同时设置在主体11的外侧。
进一步地，在一个实施例中，结合图13-15，硬质导油体1的顶部为吸液面，雾化槽10位于与吸液面邻接的一侧，硬质导油体1背离雾化槽10的一侧设置有相接于吸液面且朝底部延伸的导液结构。雾化组件4形成有连通储液腔20且相接于硬质导油体1的吸液面的导油通道（导油孔3122）以及一端连通外界大气且另一端连通出气通道311的雾化气道，雾化腔为雾化气道的一部分。
储液腔20内的雾化液可以通过导油通道流到硬质导油体1的吸液面，然后渗透到硬质导油体1的内部，在此过程中，雾化液还可以通过导液结构从发热体2的背离雾化槽10的一侧自上而下传导，从而使雾化液从背离雾化槽10的一侧朝硬质导油体1内部渗透，因此，雾化液一方面可以从顶部到底部传导向雾化槽10内壁，另一方面可以从背部传导向雾化槽10的内壁，使得雾化液可以顺畅地流向硬质导油体1的底部，使硬质导油体1被雾化液浸润更加充分，而发热体2安置于雾化槽10内且和导液结构对应的侧壁12接触连接，如此，发热体2所在区域的硬质导油体1储液量更高更均匀，雾化芯工作时不容易发生局部干烧而导致糊味，用户体验更佳。
进一步地，结合图2、5、13和14，吸液面设有朝底部凹陷的限位槽122，导液结构的顶端相接于限位槽122的底侧。具体的，雾化芯和导油通道之间可以设置导油棉413，通过导油棉413可以将雾化液更加均匀地传导至吸液面的各个位置，限位槽122用于定位装配导油棉413，实现导油棉413的稳定装配，其中，限位槽122相对的两侧为斜面，对应的，导油棉413底侧设置有匹配的斜面，如此，导油棉413在装配时可以通过斜面进行导向，更为便捷。导液结构相接于限位槽122的底侧，即导油棉413传导的雾化液可以进而通过导液结构传导至硬质导油体1的背离雾化槽10的一侧，从而实现对硬质导油体1底部位置的直接导液。
进一步地，限位槽122朝向导液结构的一端为开口端，导液结构的顶端相接于限位槽122的开口端。具体的，在本实施例中，限位槽122具有相对的两个开口端，一个开口端靠近导液结构侧，另一个开口端靠近雾化槽10侧，如此，限位槽122贯通硬质导油体1的前（雾化槽10侧）后（导液结构侧）两侧，并且，限位槽122位于硬质导油体1的中部，因此，雾化液可以更为对称而均匀地从中间朝两端传导，发热体2更为靠近雾化槽10的中间位置，雾化液可以更为集中地从硬质导油体1中间位置以及导液结构自上而下传导，因此，雾化槽10的中间位置的内壁供液更多，雾化效果更佳。在一些实施例中，限位槽122也可以仅朝向导液结构的一段为开口端，而朝向雾化槽10侧的一端为封口，如此，雾化液不易从限位槽122朝前侧传导造成雾化液直接进入到雾化槽10内，防漏液效果更好。
进一步地，导液结构包括开设于硬质导油体1背离雾化槽10的一侧的导流槽111，导流槽111的顶端贯通吸液面且底端朝硬质导油体1的底部延伸。如此，雾化液流向吸液面后可以通过导流槽111流到硬质导油体1背离雾化槽10的一侧，从而从硬质导油体1的背侧渗透向雾化槽10，相对于雾化液在硬质导油体1内从上往下的传导方式来说，本方案给发热体2供液更为均匀，更不易干烧，用户体验更佳。优选的，为了实现对发热体2更好的供液效果，在硬质导油体1的前后方向上，发热体2的发热区域和导流槽111至少部分重叠。
在一个实施例中，导液结构包括至少两个在硬质导油体1高度方向上延伸的导流槽111，导流槽111为条状，各导流槽111在雾化槽10的延伸方向上间隔排布。
通过设置多个导流槽111的方式可以保证雾化液从硬质导油体1背部自上而下的导液速率，可以提升雾化液和硬质导油体1背部的接触面积，雾化液更容易渗透到硬质导油体1内部并到达雾化槽10处，而且，多个雾化槽10的设置方式相当于给硬质导油体1增加了肋条，可以提高硬质导油体1的结构强度。
进一步地，导流槽111的延伸线为直线和曲线的至少一种。具体的，在本实施例中，硬质导油体1上开设有三个顶端相接于限位槽122的开口端的直线导流槽111，三个导流槽111的尺寸相同且在竖直方向上延伸，在雾化槽10的延伸方向上等距间隔排列，并且，在硬质导油体1上对称设置，导液更为均匀顺畅，导流槽111的底端未贯通硬质导油体1的底侧但超过雾化槽10的底侧，因此，雾化液不会直接流到硬质导油体1的底侧造成漏液，而且可以导流至硬质导油体1的底壁，在保证防漏的基础上实现更好的导液效果。
在一些实施例中，导流槽111可以是折线形或者曲线形，如此，可以增加导液路径的长度，增加雾化液和硬质导油体1之间的接触面积，从而提升导液效果。
在一些实施例中，导流槽111的数量可以为两个、四个、五个等等，尺寸可以相同或不同，并且，间距可以相同或不同。
在一些实施例中，导流槽111可以为毛细槽，其中，毛细槽的横截面积可以是0.02-0.64mm 2，导流槽111为毛细槽时可以产生毛细吸附力，从而更容易将雾化液吸附到导流槽111内，进而从导流槽111的槽壁渗入硬质导油体1内，并传导给雾化槽10。
在一些实施例中，导液结构还可以包括开设于硬质导油体1背离雾化槽10的一侧且连通各导流槽111的延伸槽。硬质导油体1的和发热体2正对处设置有横向贯穿各导流槽111的延伸槽；和/或，硬质导油体1的和其底壁对应处设置有连通各导流槽111的底端的延伸槽。进一步的，延伸槽水平或倾斜设置，延伸槽为直线或曲线形，延伸槽可以为毛细槽。具体的，硬质导油体1上优选设置两个延伸槽，两个延伸槽均为直线形且水平设置，其中一个延伸槽和雾化槽10的中部正对设置，另一个延伸槽的顶侧连通各个导流槽111的底端，如此，两个延伸槽可以进一步提升雾化液在硬质导油体1内传导的均匀性。
在一个实施例中，结合图15，导液结构还可以包括嵌置于导流槽111内的储液体13。具体的，在本实施例中，硬质导油体1的背离雾化槽10的一侧开设一个导流槽111，相对于前述的开设至少两个导流槽111的方式，本实施例的导流槽111横向长度、竖直高度和前后深度尺寸均更大，可以存储更多的雾化液，雾化液的供给更为充分，在导流槽111内嵌置储液体13一方面可以使得硬质导油体1导液更为均匀，另一方面可以具有更好的防漏液效果。
应当理解，储液体13和导油棉413可以采用相同材料，并且，两者可以一体设置或者分体设置。当储液体13和导油棉413一体设置时，储液体13连接于导油棉413的一侧边缘底部，如此，装配时导油棉413和储液体13可以同时分别嵌置于限位槽122和导流槽111内，装配更为方便快捷，进一步地，导油棉413的和储液体13相对的一侧可以具有朝下弯折的延伸缘，延伸缘贴合于雾化槽10的两个侧壁12端面，从而进一步提升导液效果。当导油棉413和储液体13分体设置时，导油棉413可以相对的两侧均具有延伸缘，两个延伸缘分别贴合于硬质导油体1的前后两侧，并且前侧的延伸缘贴合雾化槽10的两侧壁12，储液体13单独嵌置于导流槽111，后侧的延伸缘贴合储液体13的一侧。
进一步地，在硬质导油体1的高度方向上，导流槽111的尺寸为硬质导油体1尺寸的0.5-0.6倍；和/或，在雾化槽1010的延伸方向上，导流槽111111的尺寸为硬质导油体11尺寸的0.3-0.7倍。如此可以保证雾化液较好地向底部和发热体2所在的硬质导油体1部分进行导油。
应当理解，导流槽111的数量越多时，在雾化槽10的延伸方向上，导流槽111的尺寸越小。例如：当硬质导油体1设置一个导流槽111时，在雾化槽10的延伸方向上，导流槽111的尺寸为硬质导油体1尺寸的0.6-0.7倍；当硬质导油体1设置两个导流槽111时，在雾化槽10的延伸方向上，导流槽111的尺寸为硬质导油体1尺寸的0.4-0.6倍；当硬质导油体1设置三个导流槽111时，在雾化槽10的延伸方向上，导流槽111的尺寸为硬质导油体1尺寸的0.3-0.4倍。
进一步地，结合图2和图5，本实施例的雾化器100包括具有储液腔20的油杯3和装配于油杯3的雾化组件4，油杯3具有出气通道311，雾化组件4包括如上任一项的雾化芯，雾化组件4形成有连通储液腔20且相接于硬质导油体1的导油通道以及一端连通外界大气且另一端连通出气通道311的雾化气道，雾化腔为雾化气道的一部分。
雾化器100采用如本申请的雾化芯，雾化芯的雾化腔作为雾化气道的一部分，储液腔20内的雾化液可以导向硬质导油体1，然后通过硬质导油体1传导至发热体2加热雾化形成气溶胶，最后经过出气通道311导出供用户吸食，雾化性能的可靠性较好。
进一步地，雾化槽10的延伸方向可以竖直。具体的，雾化槽10的延伸方向可以平行于雾化器100的中轴方向，采用这种设置方式时，油杯3可以包括导气管，雾化组件4可以包括装配于油杯3的一端的底座411、穿设于底座411的两个电极412以及装配于底座411且和导气管密封连接的顶部支架，顶部支架和油杯3围合形成储液腔20，硬质导油体1可以夹持固定于顶部支架和底座411之间，顶部支架开设相接于硬质导油体1的一侧的导油通道，并且，发热体2的两个电极部22可以分别和两个电极412电连接，底座411开设连通雾化气道的进气口。如此，储液腔20内的雾化液可以通过导油通道导向硬质导油体1并向发热体2供给，在抽吸过程中，空气可以通过底座411的进气口进入到雾化芯的雾化腔内，发热体2将雾化液雾化形成气溶胶，最终通过导气管内的出气通道311导出外界供用户吸食。
进一步的，雾化槽10的延伸方向水平或倾斜。
在本实施例中，图2和图5分别示出了两种实现方式的硬质导油体1的雾化槽10延伸方向水平设置（垂直于雾化器100的中轴线方向）的雾化器100，其中，油杯3具有底壁312，底壁312开设导油孔3122；雾化组件4还包括底部组件41，底部组件41包括安装到油杯3下端内的底座411以及穿设在底座411中的两个电极412；雾化芯被夹持固定于底座411与底壁312之间，并通过导油孔3122吸收储液腔20内的雾化液，发热体2的两个电极部22分别与两个电极412电连接。
具体的，底壁312的底侧设置有第一嵌槽3121，底座411的顶侧设置有第二嵌槽4111，硬质导油体1分别嵌置于第一嵌槽3121和第二嵌槽4111内；雾化组件4还包括叠置于陶瓷导油体顶端的导油棉413，导油棉413覆盖导油孔3122的底部开口。导油棉413可以仅设置在硬质导油体1的顶侧，导油棉413也可以设置为包绕在硬质导油体1的周侧，发热体2的两个电极部22位于硬质导油体1的底侧的侧壁12，因此，在装配过程中，雾化芯的两个电极部22可以在同一侧实现和两个电极412的连接，方便快捷，而且，由于雾化芯嵌置在第一嵌槽3121和第二嵌槽4111内，冷凝液流到雾化腔内时，硬质导油体1和第一嵌槽3121及第二嵌槽4111之间的间隙可以用于收集冷凝液，而且冷凝液可以可以被硬质导油体1的两个侧壁12吸收，从而提高雾化液的利用率，还可以减少冷凝液的堆积。
在本实施例中，雾化腔的侧壁12与雾化器100的轴线之间夹角优选为90°，也就是说发热体2呈竖直状态设置，外部空气从进气通道313进入到雾化腔后是沿着发热体2表面经过，大大提升了发热体2的雾化效果。在实际应用过程中，也可雾化腔的侧壁12呈倾斜设置，即让发热体2呈倾斜设置，优选发热体2与雾化器100的底面之间夹角范围为60~120°。
进一步地，油杯3包括杯体31和装配于杯体31的顶端的吸嘴组件32，吸嘴组件32和杯体31围合形成储液腔20，吸嘴组件32具有和出气通道311连通的吸气孔3211；杯体31还具有与储液腔20、出气通道311均隔离的进气通道313，进气通道313连通雾化气道，杯体31的侧壁12开设有连通进气通道313和外界大气的进气孔314。
具体的，在本实施例中，进气通道313、储液腔20和出气通道311在水平方向上依次间隔设置且均为竖直延伸，进气孔314开设于杯体31的侧壁12的中部位置，进气通道313和出气通道311分别位于储液腔20的两侧，油杯3的底壁312和底座411之间形成有位于雾化腔的两端的两个缺口，两个缺口分别连通进气通道313的底端和出气通道311的底端，并且，底座411开设有连通进气通道313的底端的第一孔道4112和连通出气通道311的底端的第二孔道4113。
结合图2，在第一个示例的雾化器100中，第一孔道4112和第二孔道4113均可以设置为和外界连通，如此，第一孔道4112可以对进气通道313进行气流补充，从而提供足量的空气，第二孔道4113可以对出气通道311进行气流补充，外界空气和雾化腔内的气溶胶混合后可以使得从出气通道311流出的气溶胶温度更低，从而提升用户的抽吸体验。结合图5，在第二个示例的雾化器100中，第一孔道4112和第二孔道4113可以均作为咪头开关的感应通道，如此设置即便其中一个感应通道被堵住后，另一个感应通道仍然可以正常触发咪头开关的启动，从而提升开关启动的可靠性，第一孔道4112和第二孔道4113不和外界直接连通。
在本实施例中，吸嘴组件32包括密封件322和吸嘴321，密封件322采用硅胶、橡胶或其他柔性材料制成，密封件322安装于杯体31的上端并与储液腔20的内壁密封连接，吸嘴321通过卡扣或其他方式固定安装到杯体31的上端，以将密封件322夹持固定于杯体31和吸嘴321之间，以使密封件322保持对储液腔20密封的状态。吸气孔3211开设于吸嘴321上，密封件322上开设有第一过气孔分别与吸气孔3211和出气通道311连通。如此，本实施例通过使吸嘴组件32与杯体31设置成分体式结构，可便于杯体31以及吸嘴321的制造，以降低生产成本。
其中，密封件322的中部开设有注油孔，利用该注油孔可为储液腔20内注入雾化液，当然，注油孔也可以设置在密封件322的其他位置，只要能实现与储液腔20连通即可。吸嘴321的顶壁向密封件322方向凸出延伸密封柱3212，密封柱3212密封插入注油孔中。较佳地，吸气孔3211开设于密封柱3212中，密封柱3212的侧壁12开设有与吸气孔3211连通的开口，当使用者对着吸气孔3211进行抽吸时，混合有气溶胶的气流从出气通道311经过第一过气孔后，可从该开口进入到吸气孔3211中，从而由使用者进行吸食。也就是说，吸嘴321的吸气孔3211与出气通道311形成非直通气道，以免使用者抽吸到在出气通道311上的冷凝液。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
