Description

一种具有气液通道的气雾弹 技术领域
本发明涉及一种具有气液通道的气雾弹，特别涉及用于液体电蚊香、电香薰、电子烟和药物溶液雾化等应用领域中的具有气液通道的气雾弹。
背景技术
通过超声波雾化或电加热来散发液体的技术被广泛用于液体蚊香、香薰和电子烟等领域。在液体蚊香和香薰中，传统的方法是用芯棒将液体虹吸至顶部，用加热器气化或超声波雾化将芯棒顶部的液体挥发。对精油等高粘度液体，芯棒向上虹吸液体的速度通常难以跟上液体的雾化速度，因此，这种技术需要用大量有机溶剂将粘度较高的有效成份稀释，以提高液体的虹吸速度。大量有机溶剂的使用不仅浪费资源，并且有害人体健康。如果能将较高粘度的浓缩液直接散发，不仅可以减少资源浪费，还可以使装置小型化，使具有气液通道的气雾弹更美观、便于携带。
使用传统烟草的时候，吸入燃烧烟草时产生的焦油等有害物质，对健康影响较大。电子雾化烟采用雾化来摄入尼古丁或尼古丁盐，这种方法不产生焦油。电子雾化烟中常见的技术是加热与烟油直接连通的雾化芯，使尼古丁与溶剂一起雾化，这种技术由于对烟油导出缺乏精密控制，容易发生烟油泄漏，消费体验较差。
发明内容

进一步，流体腔道中最小横截面的最大内切圆直径为0.05mm到1mm。
进一步，气液通道与加热元件直接连通。
进一步，雾化室中设置缓冲储液体。
进一步，气液通道与加热元件通过缓冲储液体连通。
进一步，缓冲储液体由纤维或者海绵制成。
进一步，缓冲储液体包括缓冲储液体高密度部和缓冲储液体低密度部。
进一步，雾化室设置进气孔。
进一步，气雾弹包括冷凝液吸收元件。
进一步，流体芯体由纤维粘结制成。
本发明的具有气液通道的气雾弹适合于各种液体的散发，比如电子烟烟液的雾化散发，大麻二酚的雾化散发，药物溶液的雾化散发，还适合于电蚊香或电香薰液体的散发。本发明的具有气液通道的气雾弹能均匀地控制液体散发、防漏性好、结构紧凑、载液量大。为让本发明的上述内容能更明显易懂，下文特举优选实施例，并结合附图，作详细说明。

如图1a、1b和1c所示，根据本发明第一实施例的具有气液通道的气雾弹，气雾弹800包括储液元件100、加热元件和气液通道830，储液元件100和加热元件之间由气液通道830连通，气液通道830包括至少一个轴向贯穿气液通道830的流体腔道831，且气液通道830还包括流体芯体832。
<储液元件>
本发明所述的气雾弹800中，储液元件100是储存被散发液体的部件。根据应用的目的可以在其中储存不同的液体，如用于香薰的精油，或用于液体蚊香的驱蚊剂，用于电子烟的烟油，大麻二酚溶液，或用于气雾剂的药液等。储液元件100的横截面可以为多种形状，如圆形，椭圆型，长方型等，也可以为 各种几何形状的组合。储液元件100中的液体可以从气液通道注入，或者为储液元件100设置上盖，注完液体后将上盖封闭。
气雾弹800还包括气雾弹壳体810，气雾弹壳体810具有底板815和顶板818，顶板818上设置有顶板气雾孔819。储液元件100设置在气雾弹壳体810中。
储液元件100可以具有轴向贯穿储液元件100的储液元件通孔130。储液元件通孔130可以用作气雾弹800的气雾通道。
气雾通道连通雾化室934和顶板气雾孔819，其作用是将雾化室934中的气雾导出至顶板气雾孔819。气雾通道也可以与储液元件100一体成型，由储液元件通孔130作为气雾通道，也可以由塑料、金属、陶瓷或玻璃等单独成型后组装到气雾弹800中。
顶板气雾孔819是被散发的液体气化或雾化后逸出气雾弹800的部件。顶板气雾孔819可以由塑料、陶瓷或金属等制成。顶板气雾孔819通过气雾通道与雾化室934连通。如果气雾弹800的应用为电子烟，可以在气雾通道或顶板气雾孔819部位安装吸油棉，吸油棉为可以吸收冷凝液的多孔材料。电子烟中的液体被雾化后，通过气雾通道时会部分冷凝并形成冷凝液，吸油棉可以在气雾进入使用者口腔前将冷凝液吸收，从而提高吸烟体验。
<雾化部>
本发明所述的雾化部包括雾化室934和加热元件，雾化室934是液体被气化或雾化的空腔。在本实施例中，雾化室934设置在储液元件100底部和底板815之间的区域。雾化室934中设置加热元件，并可以根据需要，设置进气孔孔，例如在底板815上设置底板通孔816，作为进气孔。液体在雾化室934中被加热元件气化或雾化，并经储液元件通孔130和顶板气雾孔819逸出气雾弹800。
本发明所述的加热元件泛指能将液体按使用要求气化或雾化的部件。加热元件包括发热芯930，如缠绕在玻纤或棉花上的电热丝、预埋电热丝的多孔陶瓷、印刷厚膜发热体的陶瓷等。加热元件还可以包括导液元件200，如被电热丝缠绕的玻纤或棉花、包裹在预埋电热丝的多孔陶瓷的无纺布等。
加热元件还包括导线933。加热元件通过导线933与电源(未图示)连接。
可以采用电加热的加热元件：如将电热丝缠绕在一束玻纤或棉绳上，或者将棉花或棉质无纺布缠绕在电热丝上，或者将电热丝预埋在陶瓷中，或者将厚膜发热体印刷在陶瓷表面，或者采用正温度系数陶瓷发热体；还可以采用超声加热元件或其他类型的加热元件。根据应用要求，可以将加热元件制成各种适合于组装的形状。
雾化室934底部可以设置支撑部件935，支撑部件935可以用诸如硅胶的材料制成，以加强气液通道830和加热元件的接触连通。
由于气雾弹800在储存、运输或使用过程中发生异常情况，导致液体泄漏。可以将支撑部件935设计成由兼具缓冲和储存液体的功能的材料制成，同时雾化室934还可以设计成能够存储部分液体的结构，可以容纳从储液元件100导出的液体，从而避免液体向外界泄漏。
需要时，雾化室934中可以设置缓冲储液体(未图示)，气液通道830和加热元件可以分别与缓冲储液体连通。缓冲储液体可以储存从储液元件100导出的部分液体，还可以在气液通道830和加热元件之间传导液体。气雾弹800在储存、运输或使用过程中发生异常情况，缓冲储液体可以吸收从储液元件100导出的液体，减少液体向外界泄漏的风险。支撑部件935和缓冲储液体可以由纤维制成，纤维可以为天然纤维如棉花，也可以为天然纤维的改性产物如醋酸纤维素纤维，还可以为合成纤维如聚酯纤维、聚乳酸纤维、皮芯结构聚乙烯/聚丙烯双组份纤维等。可以将纤维粘结制成需要的形状的缓冲储液体，便于组装到气雾弹800中。另外，支撑部件935和缓冲储液体也可以由海绵制成，如聚氨酯海绵、聚乙烯醇海绵等。可以将缓冲储液体设置为高密度部和低密度部，从而更好地控制储液元件100中的液体导出并提高液体防漏能力。
<气液通道>
在本实施例中，储液元件100和加热元件之间由气液通道830连通。如图1b和图1c所示，气液通道830包括至少一个轴向贯穿气液通道830的流体腔道831，且气液通道830还包括流体芯体832。气液通道830设置在雾化室934中。
如图1b所示的一种气液通道830，气液通道830包括气液通道外管834、设置在气液通道外管834内的流体芯体832、设置在气液通道外管834和流体芯体832之间的气液通道加强筋833以及由气液通道加强筋833分隔出的流体腔道831。
如图1c所示的另一种结构的气液通道830。气液通道830包括气液通道外管834、设置在气液通道外管834内的流体芯体832以及流体腔道831。气液通道外管834与流体芯体832之间紧密配合，流体芯体832的外周部上形成多个轴向贯穿气液通道830的凹槽，该凹槽和气液通道外管834一起形成流体腔道831。
流体腔道831可以用作气体通道或者液体通道，流体腔道831中的至少一个流体腔道831用作气体通道。在平衡状态时，流体芯体832吸收足够的液体，流体芯体832周表的液体将气体通道液封。当液体从储液元件100导出时，储液元件100内真空度增加，液封气体通道 的液体被流体芯体832吸收，部分或全部流体通道831的液封消失，雾化室934中的空气通过气体通道进入储液元件100，储液元件100内真空度降低至平衡状态时，气体通道重新被液封。
流体腔道831中最小横截面的最大内切圆直径为0.05mm-1mm，本文中的“mm”均指毫米。较小内切圆直径的流体腔道831作为气体通道时液封能力较强，适合于粘度较低和出液量较小的应用。较大内切圆直径的流体腔道831作为气体通道时液封能力较弱，适合于粘度较高或出液量较大的应用。根据液体的性质和应用要求，流体腔道831的最小横截面的最大内切圆直径为0.05mm-1mm，如，0.05mm、0.08mm、0.2mm、0.5mm、0.6mm、0.8mm、1mm。在平衡状态下气体通道由于毛细力被流体芯体832周表的液体液封。
气液通道830可以与加热元件直接连通，或加热元件通过缓冲储液体与气液通道间接连通，从而使液体通过气液通道从储液元件100传导至加热元件。通常将流体芯体832设置为液体通道，流体芯体832由纤维粘结制成，比如用粘结剂将聚酯纤维粘结成流体芯体832，或者将双组份纤维热粘结成流体芯体832等。在本实施例中，流体芯体832可以参与构成气体通道。
当液体雾化时，液体经气液通道830从储液元件100被不断补充到加热元件或其周边。当外部控制装置指令加热元件工作时，加热元件上的液体被雾化，经气雾通道和顶板气雾孔819逸出气雾弹800，同时储液元件100中的液体经气液通道830的液体通道导出并补充到加热元件，随着液体的导出，储液元件100内的真空度升高至一定程度时，气液通道830的气体通道的液封被打开，雾化室934中的空气通过气体通道进入储液元件100，使储液元件100内的真空度下降，气体通道重新被液封，这个过程反复进行使雾化过程可不断进行直至储液元件100中的液体被用完。
第二实施例
图2a为根据本发明第二实施例的具有气液通道的气雾弹的结构示意图；图2b为根据第二实施例的具有气液通道的气雾弹中的气液通道的横截面示意图；图2c为根据第二实施例的具有气液通道的气雾弹中的气液通道的剖面示意图。本实施例与第一实施例结构相似，与第一实施例相同的部分在本实施例的描述中不再赘述。
在本实施例中，气液通道830的横截面和剖面分别如图2b和图2c所示。储液元件100底部设有短的气液通道外管834，将流体芯体832插在气液通道外管834中，流体芯体832和气液通道外管834之间设置有三个气液通道加强筋833。气液通道外管834的内壁、气液通道加强筋833和流体芯体832外壁之间形成流体腔道831。流体腔道831的最小横截面的最大内切圆直径为0.5mm，流体腔道831可以用作气体通道，液体通道为流体芯体832。
加热元件包括发热芯930和导液元件200。发热芯930为电热丝，导液元件200为玻纤束或棉绳，电热丝部分缠绕的玻纤束或棉绳。导液元件200与气液通道830在雾化室934内直接接触，使液体可以从储液元件100经气液通道830直接传导至加热元件的导液元件200上。
在本实施例中，雾化室934中还设置有支撑部件935，用于支撑加热元件。导液元件200的两端弯折后接由支撑部件935支撑。
本实施例的气雾弹800适合于电子烟等应用，液体导出和雾化原理与第一实施例相似，在此不再赘述。
本实施例的支撑部件935由硅胶制成，支撑部件935设计成特殊形状，例如支撑部件935的剖面视图呈两个对称的“L”形，使雾化室934中形成“洼地”。当气雾弹800在储存、运输和使用过程中遇到外界环境的异常波动时，少量液体会从储液元件100经液体通道导出并暂存于雾化室934的“洼地”中，减少液体泄漏的风险。当加热元件上的液体被消耗时，雾化室934洼地中暂存的液体会优先被消耗，因此不会造成液体在雾化室934中残留。
气雾弹800可以包括冷凝液吸收元件400。在本实施例中，如图2a所示，可以在顶板818和储液元件100之间设置冷凝液吸收元件400，可以吸收气雾中的冷凝液，进一步提高使用者的体验。
本实施例的气雾弹800在导线933的末端设置成接触式连接端，便于气雾弹800使用时与控制装置以接触方式连接。为适应不同的液体粘度、表面张力和不同的雾化速度要求，可以将流体腔道831的最小横截面的最大内切圆直径设置为小于0.5mm，如0.08mm或0.25mm，或者大于0.5mm，如0.8mm或1mm。同时，也可以设置作为液体通道的流体芯体832的横截面积和孔隙率等因素来增加或减小导液速度。当然，雾化速度还与玻纤束的大小和加热功率等因素相关。
第三实施例
图3a为根据本发明第三实施例的具有气液通道的气雾弹的结构示意图；图3b为根据第三实施例的具有气液通道的气雾弹中气液通道的横截面示意图。本实施例与第一实施例结构相似，与第一实施例相同的部分在本实施例的描述中不再赘述。
如图3a所示，本实施例中的加热元件包括发热芯930和导液元件200，发热芯930为正温度系数热敏电阻发热体(简称PTC发热体)，导液元件200由玻纤、棉花或聚酯纤维等制成。本实施例中气液通道830与第二实施例相似，横截面如图3b所示。
如果液体为低粘度的香精溶液，流体腔道831的最小横截面的最大内切圆直径设置为0.05mm；如果液体为粘度较高精油或驱蚊剂等，流体腔道831的最小横截面的最大内切圆直 径可以设置为0.1mm、0.2mm、0.5mm，甚至1mm，以便在液体导出时使气体能顺畅进入储液元件100。
本实施例尤其适合于微型香薰和微型液体蚊香等便携式气雾弹800。为简化结构，可以将储液元件100的上端用作顶板。还可以将发热芯930固定于外部控制装置中，以便重复利用发热芯930，降低使用成本。
第四实施例
图4a为根据本发明第四实施例的具有气液通道的气雾弹的结构示意图；图4b为根据第四实施例的具有气液通道的气雾弹中气液通道的横截面示意图；图4c为根据第四实施例的具有气液通道的气雾弹中的气液通道的剖面示意图。本实施例与第一实施例结构相似，与第一实施例相同的部分在本实施例的描述中不再赘述。
如图4a至4c所示，外周壁上具有轴向凹槽的流体芯体832插入储液元件100底部短管形成气液通道830，短管形成气液通道外管834。如图4b和4c所示，流体芯体832的凹槽与储液元件100底部短管内壁形成的通道构成流体腔道831，作为液体通道的流体芯体832由纤维粘结制成。流体腔道831的最小横截面的最大内切圆直径为为0.2mm，如果液体粘度较高，可以适当加大流体腔道831的最小横截面的最大内切圆直径。
在本实施例中，在雾化室934中设置缓冲储液体835，缓冲储液体835由纤维或者海绵制成，例如，由聚氨酯海绵或皮芯结构的聚乙烯/聚丙烯双组分纤维粘结制成，气液通道830与加热元件通过缓冲储液体835连通。缓冲储液体835带来的额外好处是加热元件可以更稳定地获得液体，改善雾化的稳定性，提高用户体验。吸收液体部分饱和的缓冲储液体835仍具有部分吸液性能，因此这种气雾弹800具有较好的防漏性能。
当本实施例用于电子雾化烟时，其优点在于，缓冲储液体835与导液元件200有充分的接触，如果短时间内快速雾化(俗称为“猛吸一口”)，缓冲储液体835中的液体可以快速补充给导液元件200，减少加热元件的导液元件200因暂时缺少液体而被烧焦的风险。本实施例在气雾通道的上端设置冷凝液吸收元件400，用于吸收气雾中的冷凝液，提高使用体验。
第五实施例
图5a为根据本发明第五实施例的具有气液通道的气雾弹的结构示意图；图5b为根据第五实施例的具有气液通道的气雾弹的气液通道的横截面示意图；图5c为根据第五实施例的具有气液通道的气雾弹中的气液通道的剖面示意图。本实施例与第一实施例结构相似，与第一实施例相同的部分在本实施例的描述中不再赘述。
如图5a所示，外周壁上具有轴向凹槽的流体芯体832插入储液元件100底部短管形成气 液通道830，短管形成气液通道外管834。如图5b和5c所示。流体芯体832为液体通道，流体芯体832的凹槽与气液通道外管834的内壁形成的通道为流体腔道831，流体腔道831用作气体通道。流体腔道831的最小横截面的最大内切圆直径为1mm，适合于高粘度液体的雾化，如大麻二酚的雾化。若液体粘度较低，可以适当减小流体腔道831的最小横截面的最大内切圆的直径，比如0.8mm或0.6mm。本实施例在雾化室934底部设置由聚氨酯海绵或棉花等制成的支撑部件935，支撑部件935具有缓冲储液的功能。
第六实施例
图6a为根据本发明第六实施例的具有气液通道的气雾弹的结构示意图；图6b为根据第六实施例的具有气液通道的气雾弹中的气液通道的横截面示意图；图6c为根据第六实施例的具有气液通道的气雾弹中的气液通道的剖面示意图。本实施例与第一实施例结构相似，与第一实施例相同的部分在本实施例的描述中不再赘述。
缓冲储液体835可包括缓冲储液体高密度部8351和缓冲储液体低密度部8352。在本实施例中，如图6a所示，本实施例中设置缓冲储液体835，包括靠近加热元件的缓冲储液体高密度部8351和位于外周的缓冲储液体低密度部8352，缓冲储液体高密度部8351与储液元件100底部之间设置间隙。在储液元件100底部延伸出内壁带有气液通道加强筋833的圆柱形短管，该圆柱形短管用作气液通道外管834，流体芯体832插入气液通道外管834中形成气液通道830。
如图6b和6c所示，流体芯体832为液体通道，气液通道外管834、气液通道加强筋833和流体芯体832之间形成流体腔道831，流体腔道831用作气体通道。气液通道外管834的端面抵靠缓冲储液体高密度部8351，流体芯体832插入缓冲储液体高密度部8351，流体腔道831的最小横截面的最大内切圆直径为0.8mm。
本实施例中的加热元件包括发热芯930，不设导液元件，发热芯930为预埋电热丝的多孔陶瓷。气雾弹800组装完成后，储液元件100内的液体通过气液通道830的液体通道传导给缓冲储液体高密度部8351，并进一步传导给多孔陶瓷。外界气体从气液通道830的气体通道进入储液元件100，缓冲储液体高密度部8351吸收液体后毛细力逐渐下降直到液体不再从储液元件100导出，体系到达平衡。
增加或减少流体腔道831的最小横截面的最大内切圆直径可以增加或减少体系平衡时缓冲储液体高密度部8351中液体的含量。使用时加热元件加热，液体雾化，气雾经气雾通道散发至顶板气雾孔819。加热元件从缓冲储液体高密度部8351获取液体，缓冲储液体高密度部8351中液体含量减少，毛细力上升，液体重新从储液元件100经液体通道导出至缓冲储液体高密度部8351。此过程反复进行直到储液元件100中的液体被用完。如果继续使用气雾弹800， 缓冲储液体835中的液体会继续传导至多孔陶瓷并雾化，但液体量会逐渐衰减，直到无法使用。
本实施例具有更好的防漏性能。因为通常情况下缓冲储液体低密度部8352不吸收液体，但当过量液体导出并超过缓冲储液体高密度部8351的容量时，缓冲储液体低密度部8352可以吸收多余的液体。
第七实施例
图7a为根据本发明第七实施例的具有气液通道的气雾弹的结构示意图；图7b为根据第七实施例的具有气液通道的气雾弹的气液通道的横截面示意图；图7c为根据第七实施例的具有气液通道的气雾弹的气液通道的剖面示意图。本实施例与第一实施例结构相似，与第一实施例相同的部分在本实施例的描述中不再赘述。
如图7a所示，本实施例的雾化室934中设置缓冲储液体835，缓冲储液体835包括靠近储液元件100的缓冲储液体低密度部8352和位于缓冲储液体低密度部8352下方的缓冲储液体高密度部8351。在储液元件100底部延伸出内壁带有气液通道加强筋833的圆柱形短管，该圆柱形短管用作气液通道外管834，流体芯体832插入气液通道外管834中形成气液通道830。
如图7b、7c所示，流体芯体832为液体通道，气液通道外管834、气液通道加强筋833和流体芯体832之间形成流体腔道831，流体腔道831用作气体通道。流体腔道831的最小横截面的最大内切圆直径为0.2mm。加热元件为电阻丝缠绕的玻纤束，玻纤束两端夹在缓冲储液体高密度部8351和缓冲储液体低密度部8352之间或嵌入缓冲储液体高密度部8351中。气雾弹800组装完成后，储液元件100内的液体通过气液通道830的液体通道传导给加热元件的导液元件200和缓冲储液体高密度部8351，外界气体从气体通道进入储液元件100，缓冲储液体高密度部8351吸收液体后毛细力逐渐下降直到液体不再从储液元件100导出，气体通道被液封，体系到达平衡。
使用时加热元件加热将玻纤束中的液体雾化，并经气雾通道和顶板气雾孔819散发。在雾化过程中，液体从储液元件100经液体通道补充给玻纤束，雾化室934中的气体穿过气体通道进入储液元件100。此过程不断重复直到储液元件100内的液体被用完。如果储液元件100内是特别粘稠的液体如丙三醇，可以将气体通道最小横截面的最大内切圆直径增加到0.3mm或0.5mm，以便气体通道中的液封能被顺利打开，使雾化顺利进行。如果储液元件100内的液体粘度较低，可以将气体通道最小横截面的最大内切圆直径适当减小，比如0.1mm，使气体通道获得合适的液封强度，防止液体泄漏。
本实施例在顶板气雾孔819和储液元件100之间设置冷凝液吸收元件400，用于吸收气 雾中的冷凝液，提升使用体验。
第八实施例

如图8a所示，本实施例的气雾弹800为烟斗状，包括气雾通道1303和气雾出口1301。气雾通道1303和气雾出口1301设置在雾化室934的侧面。在储液元件100底部延伸出内壁带有气液通道加强筋833的圆柱形短管，该圆柱形短管用作气液通道外管834，流体芯体832插入气液通道外管834中形成气液通道830。
如图8b、8c所示，流体芯体832为液体通道，气液通道外管834、气液通道加强筋833和流体芯体832之间形成流体腔道831，流体腔道831用作气体通道。流体腔道831的最小横截面的最大内切圆直径为0.3mm，也可以根据液体的粘度和使用要求适当增加或减少流体腔道831最小横截面的最大内切圆直径，以获得合适的气雾量。
加热元件的发热芯930为印刷厚膜发热体的陶瓷，加热元件中不设导液元件。本实施例中储液元件100中的液体经流体芯体832直接传导给发热芯930。工作时加热元件加热，流体芯体832与加热元件接触部位的液体被雾化散发，流体芯体832上的液体从储液元件100补充，其原理与第一实施例相似，此次不再赘述。
第九实施例
图9a为根据本发明第九实施例的具有气液通道的气雾弹的结构示意图；图9b为根据第九实施例的具有气液通道的气雾弹的气液通道的横截面示意图；图9c为根据第九实施例的具有气液通道的气雾弹的气液通道的剖面示意图；图9d为根据第九实施例的具有气液通道的气雾弹的第二液体通道的横截面示意图。本实施例与第一实施例结构相似，与第一实施例相同的部分在本实施例的描述中不再赘述。
如图9a所示，本实施例在储液元件100底部设置气液通道830，气液通道830通过外周壁上具有轴向凹槽的流体芯体832插入储液元件100底部短管形成，短管形成气液通道外管834。
如图9b和9c所示，流体芯体832为液体通道，流体芯体832的凹槽与气液通道外管834的内壁形成的通道为流体腔道831，流体腔道831用作气体通道。流体腔道831的最小横截面的最大内切圆直径为0.2mm，根据液体粘度，可以适当加大或减小流体腔道831的最小横 截面的最大内切圆直径。
储液元件100底部还设有第二液体通道836，第二液体通道836为一条小槽，其横截面如图9d所示，第二液体通道836与设置在雾化室934中的缓冲储液体835连通。本实施例的加热元件包括发热芯930和导液元件200，导液元件200为棉花或玻纤，发热芯930为缠绕在导液元件200上的电热丝。
导液元件200两端被夹在缓冲储液体835和硅胶制成的支撑部件935之间，本实施例的工作原理与实施例1相似。这种设置的好处在于液体的传导更加稳定可靠。
综上，本发明的具有气液通道的气雾弹适用于液体蚊香、香薰和电子烟等应用，也可以在医疗领域中用于吸入型药液的定量雾化。这种气雾弹结构紧凑、防漏性好，并能均匀地控制液体释放。如果在外部控制装置中设置气流传感器，可以根据气流来控制液体的雾化，使用更加方便。
此外，本发明上述实施例仅例示性说明本发明的原理及其功效，而非用于限制本发明。任何本领域技术人员皆可在不违背本发明的精神及范畴下，对上述实施例进行修饰或改变。因此，本领域技术人员在未脱离本发明所揭示的精神与技术思想下所完成的一切等效修饰或改变，仍应由本发明的权利要求所涵盖。
