请一并参阅图1至图6，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发生装置，本实用新型实施例提及的气溶胶发生装置一般包括雾化器以及与雾化器电性连接的电源装置。在使用气溶胶发生装置时，电源装置可向雾化器提供电能，雾化器的雾化芯200在电驱动作用下加热并雾化存储在雾化器内的雾化液，由雾化液雾化形成的气溶胶可供用户吸食。
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雾化弹主体100、雾化芯200和多孔储液介质300，雾化芯200可以是但不限于能够将雾化液雾化形成气溶胶的金属发热件4或陶瓷发热件4。雾化弹主体100的外廓呈柱状，雾化弹主体100内部设置有雾化腔7，雾化芯200设置于雾化腔7中，使得由雾化芯200雾化产生的气溶胶可释放至雾化腔7中。雾化弹主体100上分别设有出气口121、导气通道10和进气孔131，进气孔131与雾化腔7连通，导气通道10连通雾化腔7与出气口121，则用户通过出气口121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131引入雾化腔7，雾化腔7中的气溶胶先与引入雾化腔7中的空气混合后，然后与空气气流一起经由导气通道10引入出气口121，最终经由出气口121流出至用户口中。
请进一步结合参阅图1、图2和图3，雾化弹主体100内部设置有可储存雾化液的储液腔8和用于容置多孔储液介质300的收容腔9，收容腔9位于储液腔8和雾化腔7之间，多孔储液介质300容置于收容腔9中，雾化弹主体100上还分别设有进液孔221和导液口321，进液孔221连通储液腔8与收容腔9，导液口321连通收容腔9与雾化腔7，储液腔8中的雾化液可通过进液孔221传输至多孔储液介质300，使得雾化液被束缚并储存于多孔储液介质300中，同时雾化液可缓慢均匀地由多孔储液介质300传输至导液口321，从而能够防止储液腔8中的雾化液直接经由导液口321快速涌流至雾化腔7，降低雾化器发生漏液及雾化器躺卧抽吸产生干烧的风险。此外，由于多孔储液介质300设置在储液腔8和雾化腔7之间的收容腔9中，收容腔9的容积小于储液腔8的容积，在收容腔9中填充多孔储液介质300，可减小多孔储液介质300的储液 比例及多孔储液介质300的体积和/或径向尺寸，实现减小多孔储液介质300的渗透阻力，可以显著减少多孔储液介质300中雾化液的残留量，使得雾化液能够被充分雾化，从而能够有效提高雾化液的利用率，避免造成过多的雾化液残留浪费。
本实用新型实施例提供的雾化器，与现有技术相比，在雾化弹主体100内部设置有容置雾化芯200的雾化腔7和可储存雾化液的储液腔8，并在储液腔8和雾化腔7之间设置有容置多孔储液介质300的收容腔9，在雾化弹主体100上分别设有连通储液腔8与收容腔9的进液孔221和连通收容腔9与雾化腔7的导液口321。则在使用时，储液腔8中的雾化液可通过进液孔221传输至多孔储液介质300，利用多孔储液介质300将雾化液缓慢均匀地传输至导液口321，从而能够防止储液腔8中的雾化液直接经由导液口321快速涌流至雾化腔7，降低雾化器发生漏液及雾化器躺卧抽吸产生干烧的风险。并且，将多孔储液介质300设置在储液腔8和雾化腔7之间的收容腔9中，达到减小多孔储液介质300储液比例和渗透阻力的效果，可以显著减少多孔储液介质300中雾化液的残留量，使得雾化液能够被充分雾化，从而能够有效提高雾化液的利用率，避免造成过多的雾化液残留浪费。
在其中一些实施例中，多孔储液介质300的储液量占总储液量的10％～60％，总储液量为储液腔8的储液量与多孔储液介质300的储液量之和。该实施例中，将多孔储液介质300设置在储液腔8和雾化腔7之间的收容腔9中，使得多孔储液介质300的储液量占总储液量的10％～60％，在防止出现漏液或躺卧抽吸干烧现象的前提下，同时能够减小多孔储液介质300中雾化液残留量，提高雾化液的利用率。该实施例中，通过减小多孔储液介质300的雾化液在总储液量中的占比，并且减小多孔储液介质300的径向尺寸，可以减小雾化液径向渗透阻力，可以减小多孔储液介质300本身的雾化液残留量，使得储液腔8内的雾化液几乎可以消耗干净，有利于减少雾化液的残留量。进一步地，为了在防止出现漏液或躺卧抽吸干烧现象的前提下，同时能够显著减小多孔储 液介质300中雾化液残留量而提高雾化液的利用率，多孔储液介质300的储液量占总储液量的比例优选为20％～30％。需要说明的是，当多孔储液介质300的储液量占总储液量的比例小于10％时，会降低多孔储液介质300对雾化液的锁液能力，导致多孔储液介质300的储液性能降低，容易出现漏液或躺卧抽吸干烧现象；当多孔储液介质300的储液量占总储液量的比例大于60％时，会明显增大多孔储液介质300渗透阻力，造成多孔储液介质300中雾化液的残留量较多，不利于提高雾化液的利用率。
请进一步结合参阅图1、图3和图4，在其中一些实施例中，多孔储液介质300填充收容腔9，且多孔储液介质300覆盖进液孔221。该实施例中，多孔储液介质300通过进液孔221与储液腔8中的雾化液直接接触，由于进液孔221使得多孔储液介质300的一部分与储液腔8中的雾化液直接接触，相对于现有技术中将多孔储液介质300直接放置在储液腔8中引起多孔储液介质300与雾化液大面积接触，有利于防漏液及减少雾化液的残留量。并且，缩小后的进液孔221提高了储液腔8中雾化液流向多孔储液介质300的流动阻力，弥补了因多孔储液介质300体积和/或径向尺寸缩小引起多孔储液介质300对雾化液的渗透阻力变小的不足，使多孔储液介质300兼顾提高雾化液的利用率和有效防漏液的优势。此外，多孔储液介质300覆盖进液孔221，进一步提高了储液腔8中雾化液流向多孔储液介质300的流动阻力，有效弥补因多孔储液介质300体积和/或径向尺寸缩小引起多孔储液介质300对雾化液的渗透阻力变小的不足，有利于防止漏液。需要注意的是，在其中另一些实施例中，为了弥补因多孔储液介质300体积和/或径向尺寸缩小引起多孔储液介质300对雾化液的渗透阻力变小的不足，增强防止防漏液的效果，多孔储液介质300不仅可以覆盖导液口321，而且多孔储液介质300还可以同时覆盖进液孔221和导液口321。
请进一步结合参阅图2、图3和图4，在其中一些实施例中，收容腔9临近储液腔8的底部设置，且进液孔221临近储液腔8的底端设置。该实施例中，将收容腔9临近储液腔8的底部设置，即将收容腔9设置于储液腔8的底部或 者靠近储液腔8底部的位置，使得储液腔8中的雾化液在自身重力的作用下，能够稳定地经过进液孔221传输至收容腔9中的多孔储液介质300。并且，将进液孔221临近储液腔8的底端设置，即将进液孔221设置于储液腔8的底端或靠近储液腔8底端的位置，实现低位进液，使得储液腔8中雾化液尽可能全部传输至收容腔9中的多孔储液介质300，有利于减少雾化腔7中雾化液的残留，甚至可使得雾化腔7中雾化液可被全部消耗，从而有利于提高雾化液的利用率。需要说明的是，储液腔8的底端是对应于储液腔8高度位置最低的部位，即对应如下相关实施例中的第一分隔管件2的收容管段22的底端。
在其中一些实施例中，为了保证储液腔8中的雾化液能够稳定地经过进液孔221传输至收容腔9中的多孔储液介质300，以及防止输液过快而导致漏液，进液孔221的截面积控制在1～8mm2。需要注意的是，当进液孔221的截面积小于1mm2时，会引起储液腔8中的雾化液不能顺畅地通过进液孔221传输至收容腔9中的多孔储液介质300；当进液孔221的截面积大于8mm2时，使得储液腔8中的雾化液能够较顺畅地通过进液孔221传输至收容腔9中的多孔储液介质300，但会存在输液过快而导致漏液的风险。需要说明的是，进液孔221的形状可以是但不限于方形、圆形或椭圆形。为了增强储液腔8中雾化液进入收容腔9中的多孔储液介质300的均匀稳定性，防止出现局部供液不足引起的干烧问题，在雾化弹主体100上设置有多个进液孔221，多个进液孔221的截面积总和为8～32mm2。
请进一步结合参阅图1、图2和图6，在其中一些实施例中，雾化弹主体100包括储液件1、第一分隔管件2和第二分隔管件3，储液件1内部设有空腔，第一分隔管件2设置于空腔中，以使储液件1内部于第一分隔管件2之外的部分界定出储液腔8。并且，第二分隔管件3设置于第一分隔管件2中，以使第一分隔管件2内部于第二分隔管件3之外的部分界定出收容腔9。第二分隔管件3的内部形成有雾化腔7，第二分隔管件3上开设有连通雾化腔7与收容腔9的导液口321，第一分隔管件2上开设有连通储液腔8与收容腔9的进液孔221， 雾化芯200设置于雾化腔7中，多孔储液介质300设置于收容腔9中。则在使用时，储液腔8中的雾化液通过进液孔221、多孔储液介质300、导液口321传输至雾化芯200，雾化芯200雾化形成的气溶胶释放至雾化腔7，雾化腔7中的气溶胶经由第二分隔管件3输出至出气口121。
请进一步结合参阅图1、图2和图6，在其中一些实施例中，储液件1包括两端均为开口的储液管11、装配于储液管11的顶端开口上的顶盖12和装配于储液管11的底端开口上的底盖13，底盖13上设有进气孔131，顶盖12上设有出气口121，储液管11的管腔构成储液件1的空腔，第一分隔管件2设置于储液管11的管腔中，以使储液管11内部于第一分隔管件2之外的部分界定出储液腔8。并且，第二分隔管件3设置于第一分隔管件2中，以使第一分隔管件2内部于第二分隔管件3之外的部分界定出收容腔9。第二分隔管件3的内部形成有雾化腔7，第二分隔管件3上开设有连通雾化腔7与收容腔9的导液口321，第一分隔管件2上开设有连通储液腔8与收容腔9的进液孔221，雾化芯200设置于雾化腔7中，多孔储液介质300设置于收容腔9中。则在使用时，储液腔8中的雾化液通过进液孔221、多孔储液介质300、导液口321传输至雾化芯200，雾化芯200雾化形成的气溶胶释放至雾化腔7，雾化腔7中的气溶胶经由第二分隔管件3输出至出气口121。需要说明的是，顶盖12和底盖13可以是采用硅胶材料或橡胶材料制成的硅胶件，以增强密封性。
请进一步结合参阅图3和图4，在其中一些实施例中，第一分隔管件2上开设有多个进液孔221，多个进液孔221沿周向间隔布置于第一分隔管件2上，以增强储液腔8中雾化液进入收容腔9中的多孔储液介质300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221之间的间距可以相等，相邻两个进液孔221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、图3和图5，在其中一些实施例中，第一分隔管件2包括连接管段21和与连接管段21相连的收容管段22，第二分隔管件3包括 通气管段31和与通气管段31相连的分隔套管段32。请进一步结合参阅图2，通气管段31插设于第一分隔管件2的连接管段21和/或第一分隔管件2的收容管段22中，由于储液管11内部于第一分隔管件2的连接管段21和/或收容管段22之外的部分界定出储液腔8，可通过第一分隔管件2的连接管段21和/或收容管段22将通气管段31与储液腔8中的雾化液进行隔离。分隔套管段32收容于收容管段22中，分隔套管段32与收容管段22之间具有间隙，以使收容管段22内部于分隔套管段32之外的部分界定出收容腔9。分隔套管段32的内部形成有雾化腔7，分隔套管段32上开设有连通雾化腔7与收容腔9的导液口321，收容管段22上开设有连通储液腔8与收容腔9的进液孔221，雾化芯200设置于雾化腔7中，多孔储液介质300设置于收容腔9中。则在使用时，储液腔8中的雾化液通过进液孔221、多孔储液介质300、导液口321传输至雾化芯200，雾化芯200雾化形成的气溶胶释放至雾化腔7，通气管段31的管腔形成连通雾化腔7与出气口121的导气通道10，雾化腔7中的气溶胶经由通气管段31输出至出气口121。需要说明的是，出气口121可以设置在储液件1上，出气口121也可以是由通气管段31的顶端口构成。在其中另一些实施例中，第一分隔管件2包括连接管段21、与连接管段21相连的收容管段22和与收容管段22相连的底座23，通过底座23将收容管段22支撑于储液件1的空腔中。第二分隔管件3包括通气管段31、与通气管段31相连的分隔套管段32和与分隔套管段32相连的雾化座33，雾化座33可对分隔套管段32起到支撑和固定的作用，雾化芯200安装于雾化座33上。
请进一步结合参阅图1和图6，在其中一些实施例中，多孔储液介质300呈柱状，多孔储液介质300沿轴向贯穿设置有套孔，第二分隔管件3的分隔套管段32插设于套孔中，第二分隔管件3的分隔套管段32的外周壁与多孔储液介质300的内周壁之间设置有第一导液件6，多孔储液介质300与第一导液件6接触。该实施例中，在多孔储液介质300的形变能力较差时，第一导液件6可克服多孔储液介质300的形变能力较差的缺陷，使得多孔储液介质300与第一 导液件6充分接触，并利用第一导液件6对导液口321进行覆盖或充填，有利于将多孔储液介质300中的雾化液良好地通过导液口321传输至雾化芯200，防止出现局部供液不足引起的干烧问题。需要说明的是，多孔储液介质300的内周壁即为套孔的内孔壁。
请进一步结合参阅图1和图6，在其中一些实施例中，雾化芯200包括用于在通电后产生热量的发热件4和用于将雾化液传输至发热件4的第二导液件5，发热件4和第二导液件5设于雾化腔7中，第二导液件5与第二分隔管件3的分隔套管段32的内周壁贴合以覆盖导液口321。该实施例中，在雾化腔7中设置可将雾化液传输至发热件4的第二导液件5，增强雾化液传输至发热件4的均匀稳定性，防止出现局部供液不足引起的干烧问题。
请进一步结合参阅图1和图6，在其中另一些实施例中，多孔储液介质300呈柱状，多孔储液介质300沿轴向贯穿设置有套孔，分隔套管段32插设于套孔中，分隔套管段32的外周壁与多孔储液介质300的内周壁之间设置有第一导液件6，多孔储液介质300与第一导液件6接触，发热件4和第二导液件5设于雾化腔7中，第二导液件5与分隔套管段32的内周壁贴合以覆盖导液口321，第一导液件6通过导液口321与第二导液件5接触，多孔储液介质300中的雾化液通过第一导液件6、导液口321、第二导液件5传输至发热件4，能够增强多孔储液介质300中的雾化液传输至发热件4的稳定可靠性，同时也具有一定的防漏液作用。需要说明的是，在其中一些具体实施方式中，多孔储液介质300可以是但不限于多孔棉导液体、多孔海绵导液体或多孔玻璃纤维导液体等。在多孔储液介质300采用多孔棉导液体时，多孔棉导液体可以采用束缚液体性能好、储液能力强，且导液性能好的烟丝棉或高分子一体棉。当然多孔棉导液体也可以采用压缩棉等。
在其中一些实施例中，由进液孔221至导液口321的方向，多孔储液介质300的孔径和/或孔隙率逐渐变小，可使得多孔储液介质300靠近进液孔221的部分具有较高的导液速率，进而使得多孔储液介质300靠近进液孔221的部分 可逐渐向多孔储液介质300靠近导液口321的部分稳定地传输雾化液，避免出现多孔储液介质300靠近导液口321的部分出现供液不足的现象，且能够保证多孔储液介质300在锁液能力与导液效率之间取得平衡。
