实施例：
在本实施例中，提供一种电子雾化装置，包括雾化器，其中，结合图1至图5，雾化器包括：油杯1、通气管2以及雾化芯3；油杯1具有储液腔11；通气管2安装于储液腔11内，通气管2开设连通储液腔11的进液孔；雾化芯3嵌入固定于通气管2内并与进液孔流体连通，雾化芯3与通气管2的部分内壁共同围合形成至少一个雾化腔4。
由于雾化芯3和通气管2的内壁之间设有雾化腔4，且通气管2在储液腔11内，使得通气管2为储液腔11和雾化腔4之间的界壁，在雾化芯3加热雾化时，雾化腔4内的热量会通过通气管2传导至储液腔11内，并对储液腔11所储存的雾化液进行预热，从而提高雾化液的流通性，提高导油速率，进而提升雾化芯3的供油顺畅性。
在本实施例中，通气管2的制成材料包括导热材料，尤其是高导热材料，可以提升通气管2吸收雾化腔4内的热量的能力，从而确保储液腔11内的雾化液预热充分。
进一步地，导热材料包括金属材料，金属材料可以为铜、铝和银中的一种，也可以为合金材料。在一些实施例中，导热材料也可以为金刚石、石墨烯和陶瓷等非金属材料。
请参阅图1、图2和图3，进一步地，雾化芯3包括与进液孔流体连通硬质导油体31和固定于硬质导油体31的发热体32，硬质导油体31的外侧与通气管2的内壁之间设有至少一个雾化腔4，发热体32位于雾化腔4内。硬质导油体31为矩形体，硬质导油体31可以采用陶瓷材料，优选为多孔陶瓷材料，其具有良好的吸油和锁油功能；由于发热体32位于雾化腔4内，使得发热体32在加热雾化硬质导油体31储存的雾化液时会在雾化腔4内产生热量，通气管2吸收该热量从而现对储液腔11所储存的雾化液进行预热。在一些实施例中，硬质导油体31也可以采用玻璃纤维体等内部具有孔隙结构的材料，雾化腔4根据实际需要可以为一个、两个或其他数量，雾化腔4越多，则通气管2所吸收的热量也越多，导热更快，有利于雾化液进行预热。
具体的，雾化腔4既可以由通气管2的内壁覆盖开设于硬质导油体31的外侧的凹槽311形成，也可以由硬质导油体31的外侧与通气管2的内壁间隔形成。
请参阅图3、图4和图5，在一个实施例中，硬质导油体31的外侧设有至少一个凹槽311，且凹槽311的长度沿通气管2的轴向延伸，凹槽311的槽口朝向通气管2的内壁，通气管2的内壁至少部分覆盖凹槽311的槽口，以形成雾化腔4。具体的，凹槽311开设于硬质导油体31的周侧，每一凹槽311由槽底和连接于槽底且相对设置的两槽侧壁连接形成，通过控制凹槽311的槽底相对硬质导油体31的外侧表面的深度，可以控制雾化腔4的大小，从而有利于雾化腔4的精准成型；凹槽311的槽口朝向通气管2的内壁，有利于通气管2的内壁覆盖凹槽311的槽口。优选地，凹槽311的两槽侧壁的厚度相等，使得雾化液在硬质导油体31内传导的过程中，凹槽311的两槽侧壁储存的雾化液含量保持相同，有利于发热体32在雾化腔4内加热雾化生成气溶胶。可以理解的，由于凹槽311的长度沿通气管2的轴向延伸，便于发热体32加热雾化生成的气溶胶在通气管2内流动，从而提升气溶胶的流动速度，有利于提升用户的抽吸体验；同时，发热体32设置于凹槽311内，凹槽311的槽侧壁可以阻挡发热体32发出的热量朝两侧传导，发热体32所发出的热量可以更加集中地用于雾化液的雾化，从而提高热能的利用率。
请参阅图3、图4和图5，进一步地，硬质导油体31的同一侧设置两相邻的凹槽311，或者硬质导油体31的一侧设置一个凹槽311，或者硬质导油体31的相邻两侧分别设置凹槽311，或者硬质导油体31的相对两侧分别设置凹槽311。当在硬质导油体31的同一侧设置两相邻的凹槽311时，形成E字型雾化芯3，雾化腔4内生成的气溶胶从雾化芯3的一侧流动至通气管2内，热量从雾化芯3的一侧传导至通气管2的内壁；当硬质导油体31的相对两侧分别设置凹槽311时，形成工字型雾化芯3，雾化腔4内生成的气溶胶从雾化芯3的相对两侧流动至通气管2内，热量从雾化芯3的相对两侧传导至通气管2的内壁；当硬质导油体31的相对两侧分别设置凹槽311时，形成不规则型雾化芯3，雾化腔4内生成的气溶胶从雾化芯3的相邻两侧流动至通气管2内，热量从雾化芯3的相邻两侧传导至通气管2的内壁；当硬质导油体31的一侧设置一个凹槽311时，形成U字型雾化芯3，雾化腔4内生成的气溶胶从雾化芯3的一侧流动至通气管2内，热量从雾化芯3的一侧传导至通气管2的内壁。优选地，雾化芯3为工字型，其结构较为紧凑，有利于小型化产品；且两个雾化腔4在通气管2内的分布较为均衡，热量传导较快，其预热效果好，且雾化充分。
请参阅图3、图4和图5，进一步地，每一个凹槽311内设置至少一个发热体32，发热体32位于凹槽311的槽壁与通气管2的内壁相邻或相对的位置。具体的，发热体32包括固定于槽壁的连接部321和固定于连接部321的发热部322，连接部321可以固定在凹槽311的槽底或凹槽311的槽侧壁，发热部322可以为发热丝，发热丝位于雾化腔4内。当一个凹槽311内设置一个发热体32时，发热体32的连接部321固定在凹槽311的槽底，此时发热体32的发热部322处于雾化腔4的中部，使得发热体32产生的热量在雾化腔4内的分布更加均衡，提升雾化芯3的加热雾化效果。根据实际需要，可以在一个凹槽311内设置两个和三个发热体32，当一个凹槽311内设有两个发热体32时，两个发热体32分别在凹槽311的相对两槽侧壁上；当一个凹槽311内设有三个发热体32时，三个发热体32分别位在凹槽311的槽底和两槽侧壁上，或者三个发热体32均固定在凹槽311的槽侧壁上，此时三个发热体32沿凹槽311的长度方向等距间隔排列设置。
请参阅图3、图4和图5，较佳地，凹槽311贯穿硬质导油体31的两端，使得气流可以从凹槽311的一端流入雾化腔4内，然后从凹槽311的另一端流出雾化腔4，并流动至通气管2内，从而有利于气流携带雾化腔4内生成的气溶胶流动。在一些实施例中，凹槽311也可以不贯穿硬质导油体31的端部，或者，凹槽311仅贯穿硬质导油体31的一端。
请参阅图2至图5，进一步地，凹槽311的横截面为扇形、梯形、矩形中的一种。优选地，凹槽311的横截面可以为矩形，既有利于扩大雾化腔4的空间，也有利于凹槽311在硬质导油体31上加工成型。在一些实施例中，凹槽311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，凹槽311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4的中部位置处流速更大，可以带动发热体32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，凹槽311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。
在一个实施例中，硬质导油体31包括至少一个雾化面和至少一个吸液面，吸液面抵接于通气管2的内壁，雾化面与通气管2的内壁间隔设置，且雾化面与通气管2的内壁共同围合形成雾化腔4。
作为示例的，以硬质导油体31具有四个侧面的长方体行为例，长方体形硬质导油体31的一个侧面为吸油面，其他三个侧面为吸液面，吸液面与通气管2的内壁接触，雾化面与通气管2的内壁间隔且围合形成雾化腔4；或者，长方体形硬质导油体31的两相对的侧面为吸液面，吸液面与通气管2的内壁接触，另外两相对的侧面为雾化面且分别于通气管2的内壁间隔设置，以形成两个雾化腔4。
请参阅图1，进一步地，通气管2包括管径逐渐增大且依次连通设置的出气段21、连接段22和雾化段23，雾化芯3位于雾化段23内，进液孔设于雾化段23。由于出气段21、连接段22和雾化段23的管径逐渐增大，使得雾化段23的内部空间大于连接段22的内部空间，连接段22的内部空间大于出气段21的内部空间，雾化段23、连接段22和出气段21之间容易产生气压差，在雾化段23内产生气溶胶后，有利于气溶胶从雾化段23内流动至出气段21内，提升气溶胶的生成速率，进一步提升用户的抽吸体验；进液孔设于雾化段23内，此时进油孔的进油方向与气流在雾化腔4内的流动方向相垂直，有利于雾化液从进液孔进入雾化段23内。连接段22更靠近雾化段23的一端的管径大于更远离雾化段23的一端的管径，此时连接段22呈锥形漏斗状，实现雾化段23和出气段21之间的过渡连接，同时也有利于通气管2的加工成型。应当理解，由于出气段21、连接段22和雾化段23的管径逐渐增大，设有进液孔的雾化段23的外侧与油杯1的内壁之间的距离较小，使得对应处的储液腔11储存的雾化液较少，有利于提升雾化液加热升温的速度，降低预热时间，从而提升进液速率。
较佳地，发热体32沿通气管2的轴向的投影至少部分落入出气段21沿通气管2的轴向的投影所围合的区域内，使得雾化腔4直接与出气段21连通，可以保证气流及时向外输送，减少滞留在连接段22内的概率，从而降低冷凝液的形成概率。具体的，发热体32平行于通气管2的中心轴线，且发热体32与出气段21的内壁的最小间距为预定值，预定值的取值范围为0.1mm-2.5mm，优选为0.5mm-2mm，例如0.5mm、0.9mm、1.1mm、1.4mm、1.8mm以及2mm等。
请参阅图1、图2和图3，进一步地，硬质导油体31与雾化段23设有进液孔的内壁之间设有导油件5，导油件5与硬质导油体31流体连通，导油件5可以为导油棉，导油件5可以将储液腔11内的雾化液输送至硬质导油体31内。应当理解，在E字型、U字型、以及工字型雾化芯3中，两导油件5分别设置在硬质导油体31未设置凹槽311的相对两侧，有利于硬质导油体31将雾化液均衡的传导至凹槽311的槽侧壁上，从而有利于发热体32加热雾化生成气溶胶；同时，硬质导油体31的另外两侧中的至少一侧与通气管2的内壁之间设有回气间隙。
请参阅图3和图4，较佳地，导油件5覆盖硬质导油体31的顶端，导油件5设有与凹槽311连通的出气口51。其中，两导油件5连接成一体设置，可以增加导油件5和硬质导油体31的接触面积，从而进一步提升雾化芯3的供油效率；出气口51的面积大于凹槽311的顶部开口，可以避免因出气口51的面积过小，导致气溶胶无法及时排出，从而在出气口51处形成较多的冷凝液。
请参阅图1，进一步地，油杯1的顶端开设连通通气管2的吸嘴口12、底端开口，雾化芯3还包括嵌入固定于所述油杯1的底端内的支架33，通气管2的一端与环绕吸嘴口12的开口的周壁密封连接，另一端与支架33密封连接，油杯1的内壁、通气管2以及支架33共同围合形成储液腔11。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
