为实现上述目的，本实用新型采用的技术方案是：提供一种气溶胶生成装置，包括上述任一方案提供的所述雾化器。
本实用新型实施例中的上述一个或多个技术方案，与现有技术相比，至少具有如下有益效果之一：
本实用新型实施例中的雾化器及气溶胶生成装置，雾化器结构中，在储液单元内部设置有容置雾化单元的雾化腔和可储存雾化液的储液腔，并在储液腔和雾化腔之间设置有容置供液缓冲腔，在储液单元上分别设有连通储液腔与供液缓冲腔的进液孔和连通供液缓冲腔与雾化腔的导液孔。则在使用时，仅需在供液缓冲腔中设置引流单元，储液腔中的雾化液便可通过进液孔稳定地传输至引流单元，利用引流单元的多孔结构具有的导液性能与锁液性能，将雾化液缓慢均匀地通过导液孔传输至雾化腔中的雾化单元。这样，供液缓冲腔中的引流单元作为进液孔与导液孔之间液体传输的隔离缓冲区域，可限定并减缓储液腔向雾化腔中的雾化单元的供液速率，有效防止储液腔中的雾化液直接通过进液孔快速流入雾化腔，从而有效降低漏液风险。

请一并参阅图1至图5，现对本实用新型实施例提供的雾化器进行说明。本实用新型实施例提供的雾化器适用于气溶胶生成装置，本实用新型实施例提 及的气溶胶生成装置，一般包括雾化器以及与雾化器电性连接的电源装置5。在使用气溶胶生成装置时，电源装置5可向雾化器提供电能，雾化器的雾化单元2在电驱动作用下，将存储在储液单元1内的雾化液雾化形成可供用户吸食的气溶胶。
请进一步结合参阅图1、图2和图3，本实用新型实施例提供的雾化器包括储液单元1、雾化单元2和引流单元3，雾化单元2用于将雾化液雾化形成气溶胶。雾化单元2可以是但不限于能够将雾化液雾化形成气溶胶的金属雾化芯或陶瓷雾化芯。储液单元1内部设置有雾化腔15，雾化单元2设置于雾化腔15中，使得由雾化单元2雾化产生的气溶胶可释放至雾化腔15中。储液单元1上分别设有出气口114、导气通道115和进气孔113，进气孔113与雾化腔15连通，导气通道115连通雾化腔15与出气口114，则用户通过出气口114抽吸气溶胶时，在抽吸形成的负压作用下，外部空气由进气孔113引入雾化腔15，雾化腔15中的气溶胶先与引入雾化腔15中的空气混合后，然后与空气气流一起经由导气通道115引入出气口114，最终经由出气口114流出至用户口中。
请进一步结合参阅图2、图3和图4，储液单元1的外廓呈柱状，储液单元1用于储存雾化液的储液腔14和用于容置引流单元3的液缓冲腔，供液缓冲腔18位于储液腔14和雾化腔15之间，储液单元1上还分别开设有进液孔16和导液孔17，进液孔16连通储液腔14与供液缓冲腔18，导液孔17连通供液缓冲腔18与雾化腔15，引流单元3容置于供液缓冲腔18中。则在使用雾化器时，储液腔14中的雾化液可通过进液孔16与液缓冲腔中的引流单元3接触，引流单元3便可通过进液孔16吸附储液腔14中的雾化液，并将吸附和/或储存的雾化液经由导液孔17传输至雾化腔15中的雾化单元2，使得储液腔14中的雾化液经由进液孔16、引流单元3、导液孔17传输至雾化腔15中的雾化单元2。由于引流单元3的多孔结构具有一定的锁液能力，可将雾化液束缚并储存于引流单元3中，且引流单元3的毛细结构可缓慢均匀地将吸附和/或储存的雾化液经由导液孔17传输至雾化腔15中的雾化单元2，使得供液缓冲腔18中的引流 单元3作为进液孔16与导液孔17之间液体传输的隔离缓冲区域，以限定并减缓储液腔14向雾化腔15中的雾化单元2的供液速率，有效防止储液腔14中的雾化液直接通过进液孔16流入雾化腔15，从而有效降低漏液风险。
本实用新型实施例提供的雾化器，与现有技术相比，在储液单元1内部设置有容置雾化单元2的雾化腔15和可储存雾化液的储液腔14，并在储液腔14和雾化腔15之间设置有容置供液缓冲腔18，在储液单元1上分别设有连通储液腔14与供液缓冲腔18的进液孔16和连通供液缓冲腔18与雾化腔15的导液孔17。则在使用时，仅需在供液缓冲腔18中设置引流单元3，储液腔14中的雾化液便可通过进液孔16稳定地传输至引流单元3，再利用引流单元3的多孔结构具有的导液性能与锁液性能，便可将雾化液缓慢均匀地通过导液孔17传输至雾化腔15中的雾化单元2。这样，供液缓冲腔18中的引流单元3作为进液孔16与导液孔17之间液体传输的隔离缓冲区域，可限定并减缓储液腔14向雾化腔15中的雾化单元2的供液速率，有效防止储液腔14中的雾化液直接通过进液孔16快速流入雾化腔15，从而有效降低漏液风险。因此，本实用新型实施例提供的雾化器，可良好克服储液单元1与雾化单元2通过进液孔16直接导液连通的缺陷，避免储液单元1中的雾化液通过进液孔16直接快速流入雾化单元2，防止雾化器出现漏液而造成雾化液污染电子元器件或引起电子元器件失灵。
请进一步结合参阅图2和图3，在其中一些实施例中，进液孔16临近储液腔14的底端设置，导液孔17的设置高度高于进液孔16的设置高度。该实施例中，进液孔16临近储液腔14的底端设置，使得储液腔14中的雾化液通过储液腔14的底部传输至供液缓冲腔18中的引流单元3，使得供液缓冲腔18中的引流单元3能够较好地作为进液孔16与导液孔17之间液体传输的隔离缓冲区域，增强限定并减缓储液腔14向雾化腔15中的雾化单元2供液速率的效果。同时，导液孔17的设置高度高于进液孔16的设置高度，雾化单元2的设置高度与导液孔17的设置高度保持一致，由底部传输至引流单元3的雾化液，可在引流单 元3的多孔结构具有的毛细现象的作用下，由底部竖直传输至导液孔17，达到向雾化腔15中的雾化单元2供液的目的，能够限定并减缓储液腔14向雾化腔15中的雾化单元2供液速率，有利于提高防漏液的效果。需要说明的是，导液孔17可以临近储液腔14的顶端设置，导液孔17也可以临近储液腔14的中部设置，导液孔17还可以是临近储液腔14的底端设置，仅需保证导液孔17的设置高度高于进液孔16的设置高度，便可使得引流单元3由底部竖直向上传输雾化液，以对进液孔16与导液孔17之间液体传输起到良好的隔离缓冲作用，有效防止储液腔14中的雾化液直接通过进液孔16快速流入雾化腔15，降低漏液风险。
请进一步结合参阅图2，在其中一些实施例中，引流单元3填充供液缓冲腔18，引流单元3覆盖进液孔16和/或导液孔17。由于引流单元3设置在储液腔14和雾化腔15之间的供液缓冲腔18中，供液缓冲腔18的容积小于储液腔14的容积，在供液缓冲腔18中填充引流单元3，引流单元3通过进液孔16与储液腔14中的雾化液直接接触，由于进液孔16使得引流单元3的一部分与储液腔14中的雾化液直接接触，且引流单元3覆盖进液孔16和/或导液孔17，提高了储液腔14中雾化液通过进液孔16传输至导液孔17的流动阻力，增强防止防漏液的效果。需要说明的是，引流单元3覆盖进液孔16和/或导液孔17，是指引流单元3可以是仅覆盖进液孔16或导液孔17，而且引流单元3还可以同时覆盖进液孔16和导液孔17。可以理解地，引流单元3填充供液缓冲腔18，包括引流单元3填满整个供液缓冲腔18和引流单元3未填满供液缓冲腔18两种不同的使用情形。
请进一步结合参阅图1、图3和图4，在其中一些实施例中，储液单元1包括储液件11、第一套管12和第二套管13，储液件11内部设有空腔，第一套管12设置于空腔中，第二套管13设置于第一套管12中，储液件11内部于第一套管12之外的部分界定出储液腔14，第一套管12内部于第二套管13之外的部分界定出供液缓冲腔18，第二套管13的内部形成有雾化腔15，第二套管 13上开设有导液孔17，第一套管12上开设有进液孔16。该实施例中，储液件11内部于第一套管12之外的部分界定出储液腔14，第一套管12内部于第二套管13之外的部分界定出供液缓冲腔18，第二套管13的内部形成有雾化腔15，使得供液缓冲腔18沿竖直方向分隔储液腔14与雾化腔15。由于进液孔16连通储液腔14与供液缓冲腔18，导液孔17连通供液缓冲腔18与雾化腔15，仅需将引流单元3容置于供液缓冲腔18中，储液腔14中的雾化液可通过进液孔16与引流单元3接触，引流单元3便可通过进液孔16吸附储液腔14中的雾化液，并将吸附和/或储存的雾化液经由导液孔17传输至雾化腔15中的雾化单元2，使得储液腔14中的雾化液经由进液孔16、引流单元3、导液孔17传输至雾化腔15中的雾化单元2。由于引流单元3的多孔结构具有一定的锁液能力，可将雾化液束缚并储存于引流单元3中，且引流单元3的毛细结构可缓慢均匀地将吸附和/或储存的雾化液经由导液孔17传输至雾化腔15中的雾化单元2，使得供液缓冲腔18中的引流单元3作为进液孔16与导液孔17之间液体传输的隔离缓冲区域，以限定并减缓储液腔14向雾化腔15中的雾化单元2的供液速率，有效防止储液腔14中的雾化液直接通过进液孔16流入雾化腔15，从而有效降低漏液风险。
在其中一些实施例中，第一套管12上开设有多个进液孔16，多个进液孔16沿周向间隔布置于第一套管12上，以增强储液腔14中雾化液传输至供液缓冲腔18中的引流单元3的均匀稳定性，防止出现局部供液不足引起的干烧问题。需要注意的是，相邻两个进液孔16之间的间距可以相等，相邻两个进液孔16之间的间距也可以不相等，具体可根据实际需要而选取设置。
请进一步结合参阅图2和图4，在其中一些实施例中，雾化单元2包括用于在通电后产生热量的发热件21和用于将雾化液传输至发热件21的第一导液件22，发热件21和第一导液件22设于雾化腔15中，第一导液件22与第二套管13的内周壁贴合以覆盖导液孔17。该实施例中，在雾化腔15中设置可将雾化液传输至发热件21的第一导液件22，第一导液件22与第二套管13的内周 壁贴合，且第一导液件22覆盖导液孔17，有利于提高防漏液效果，需要说明的是，发热件21可以是但不限于金属发热丝、金属发热片或金属发热膜等，第一导液件22可以是但不限于无纺布、棉、海绵、玻璃纤维、多孔陶瓷或多孔石墨等。
请进一步结合参阅图2、图3和图4，在其中一些实施例中，储液件11包括壳体111和密封座112，壳体111上设有用于供气溶胶流出的出气口114，密封座112上设有用于将外部空气引入雾化腔15的进气孔113，密封座112装配于壳体111的底端开口中，第二套管13的底端支撑于密封座112。可以理解地，密封座112可以是但不限于硅胶件或橡胶件，以增强密封座112与第二套管13之间的连接的密封性。第一套管12包括缩颈管段121和与缩颈管段121相连的收容管段122，第二套管13容置于收容管段122中，缩颈管段121与第二套管13相连，第二套管13与收容管段122之间具有间隙，以使收容管段122内部于第二套管13之外的部分界定出供液缓冲腔18，收容管段122上开设有进液孔16。该实施例中，第一套管12包括缩颈管段121和收容管段122，收容管段122与缩颈管段121相连，由于第二套管13的管径小于收容管段122的管径，仅需将第二套管13容置于收容管段122中，第二套管13与收容管段122之间具有间隙，使收容管段122内部于第二套管13之外的部分界定出供液缓冲腔18。缩颈管段121的一端连通第二套管13与出气口114，缩颈管段121的另一端与第二套管13的顶端相连，使得缩颈管段121的管道构成连通出气口114和雾化腔15的导气通道115。为了方便向储液腔14中添注雾化液，壳体111上设有注液口116，储液件11还包括设于注液口116上的注液塞19。
请进一步结合参阅图2和图4，在其中一些实施例中，引流单元3呈柱状，引流单元3沿轴向贯穿设置有套孔31，第二套管13插设于套孔31中，第二套管13的外周壁与引流单元3的内周壁之间设置有第二导液件4，引流单元3与第二导液件4接触，第二导液件4与第二套管13的外周壁贴合以覆盖导液孔17。该实施例中，在第二套管13的外周壁与引流单元3的内周壁之间设置有第 二导液件4，且利用第二导液件4覆盖导液孔17，一方面增强引流单元3传输雾化液均匀稳定性，另一方面有利于提高防漏液效果。可以理解地，在一些具体实施方式中，引流单元3为棉、海绵、玻璃纤维、多孔陶瓷和多孔石墨中的至少一种。
请进一步结合参阅图2和图4，在其中一些实施例中，引流单元3呈柱状，引流单元3的顶端高度高于导液孔17的设置高度，雾化单元2的设置高度与导液孔17的设置高度保持一致。在未使用雾化器时，由底部传输至引流单元3的雾化液，可在引流单元3的多孔结构具有的毛细现象的作用下，由底部竖直传输至引流单元3的顶端，由于引流单元3的多孔结构具有良好的锁液性能，可将雾化液束缚于引流单元3的多孔结构中，防止出现漏液。在使用雾化器时，由于引流单元3的多孔结构同时具有的良好导液性能，束缚于引流单元3的多孔结构中的雾化液，便可缓慢均匀地通过导液孔17传输至雾化腔15中的雾化单元2。这样，供液缓冲腔18中的引流单元3作为进液孔16与导液孔17之间液体传输的隔离缓冲区域，可限定并减缓储液腔14向雾化腔15中的雾化单元2的供液速率，有效防止储液腔14中的雾化液直接通过进液孔16快速流入雾化腔15，从而有效降低漏液风险。
请结合参阅图5，本实用新型实施例还提供一种气溶胶生成装置，该气溶胶生成装置包括上述任一实施例提供的雾化器和向雾化器供电的电源装置5。由于气溶胶生成装置具有上述任一实施例中提供的雾化器的全部技术特征，故其具有与上述雾化器相同的技术效果。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
