如图1a所示，根据本发明第一实施例气雾弹800，包括储液元件100、雾化芯930、和连通储液元件100和雾化芯930的气液交换元件290，雾化芯930至少部分位于气液交 换元件290的底部上方，气液交换元件290将储液元件100中的液体传导至雾化芯930，并且通过气液交换元件290将气体补充到储液元件100。
由于雾化芯930至少部分位于气液交换元件290的底部上方，雾化芯930至少部分可以与气液交换元件290的底部以外的部分接触，例如，雾化芯930仅与气液交换元件290的内周壁接触，通过气液交换元件290的内周壁将液体传导至雾化芯930，这种设置，可以使气雾弹800的结构更加紧凑，有利于气雾弹800小型化。
气雾弹800还包括气雾弹壳体810、设置在气雾弹壳体810底部的壳体底座112、设置在气雾弹壳体810内部的雾化室腔体9342、由雾化室腔体9342和壳体底座112围成的雾化室934和从雾化室腔体9342顶部延伸至气雾弹壳体810顶部的气雾通道1303。
由于气雾弹800包括雾化室腔体9342，储液元件100具有轴向贯穿所述储液元件100的气雾通道1303，气雾通道1303的一端与雾化室腔体9342连通，在雾化室腔体9342内雾化的气雾通过气雾通道1303逸出。
如图1a所示，在本实施例中，气液交换元件290和雾化芯930容纳在雾化室腔体9342内，雾化室腔体9342上设置雾化室通孔9341，储液元件100中的液体通过雾化室通孔9341接触气液交换元件290。
储液元件100可以单独成型，也可以是由气雾弹壳体810、气雾通道1303的壁部、雾化室腔体9342以及壳体底座112围成的空间形成。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可以同时用作气雾通道1303。雾化芯930设置在雾化室934内。
雾化室腔体9342上设置有连通雾化室934和储液元件100的贯穿雾化室腔体9342的雾化室通孔9341。如图1b，1c所示，气液交换元件290为管状的结构，管状的气液交换元件290具有轴向贯穿气液交换元件通孔2903。
气液交换元件290的外周壁与雾化室通孔9341紧配，气液交换元件290封堵雾化室通孔9341，并通过雾化室通孔9341与储液元件100中的液体接触。气液交换元件290的内周壁与雾化芯930接触，由此，将储液元件100中的液体传导至雾化芯930。
<气液交换元件>
如图1b和1c所示，气液交换元件290由纤维粘结制成三维网络的立体结构。优选采用热粘接的方式。本发明的气液交换元件290的密度为0.035-0.3克/厘米 3，例如，0.035/厘米 3、0.050/厘米 3、0.065/厘米 3、0.080/厘米 3、0.100/厘米 3、0.125/厘米 3、0.150/厘米 3、0.175/厘米 3、0.200/厘米 3、0.225/厘米 3、0.250/厘米 3、0.275/厘米 3、0.300/厘米 3，优选 为0.05-0.2克/厘米 3。当密度小于0.035克/厘米 3时，气液交换元件290制作困难并且强度不足，装配时容易变形或褶皱，影响雾化的稳定性或造成漏液。当密度大于0.3克/厘米 3时，气液交换元件290向储液元件100补充气体的能力不足，储液元件100中的负压过高而使液体难以导出。
<纤维和双组分纤维>
气液交换元件290由纤维粘结制成，可以用单组分纤维如聚酰胺6、聚酰胺66、聚酰胺610、PET、PBT、PTT等由粘结剂或增塑剂粘结制成气液交换元件290，也可以用双组分纤维粘结制成气液交换元件290。

制作本发明气液交换元件290的双组分纤维2的纤度介于1.5-50旦，优选3-30旦。介于3-30旦的皮芯结构双组分纤维2容易制作气液交换元件290。被雾化的液体粘度较低时，宜采用纤度较小的纤维制作气液交换元件290，如1.5旦、2旦、3旦的纤维。被雾化的液体粘度较高时，宜采用纤度较大的纤维制作气液交换元件290，如6旦、10旦、30旦、50旦的纤维。
在本实施例中，优选气液交换元件290由双组分短维经热粘结形成三维网络的立体结构。皮层21为熔点125-135℃的聚乙烯，芯层22为熔点160-170℃的聚丙烯或PET，制成的气液交换元件290密度介于0.035-0.3克/厘米 3，优选0.05-0.2克/厘米 3，这种气液交换元件290具有较好的强度和较好的弹性，并具有较快的液体传导速度和向储液元件100补充气体的能力。这种气液交换元件290可以用于电子烟烟液的雾化、CBD药液的雾化等。
本实施例中双组分纤维2的皮层21可以用聚丙烯、Co-PET、聚酰胺-6、PBT或PTT等替代，制成的气液交换元件290具有更高的耐温性能。
<雾化芯>
本发明中可以使用常见的雾化芯930，如预埋电热丝的多孔陶瓷雾化芯930、预埋电热丝的压缩棉雾化芯930、缠绕电热丝的棉纤束雾化芯930、缠绕电热丝的玻纤束雾化芯930、包覆织布或不织布的螺旋状电热丝雾化芯930等。在本实施例中，雾化芯930为预埋电热丝的多孔陶瓷并设计为管状。管状气液交换元件290外壁的一部分直接接触储液元件100中的液体，液体在气液交换元件290中沿轴向和径向渗透，并通过气液交换元件290传导给雾化芯930。雾化芯930通过导线933及导线引脚936与电源连接。
<储液元件>
储液元件100为气雾弹800中储存液体的部件，储液元件100中注入待雾化的液体。储液元件100可以为塑料或金属制成的空腔，或者在空腔中填充储存液体的多孔材料。储液元件100中的液体通过气液交换元件290传导给雾化芯930，在需要时被雾化。
本实施例中，储液元件100为金属或塑料制成的空腔，被雾化的液体注入其中。使用时随着储液元件100中的液体导出，外界空气可以通过气液交换元件290进入储液元件100。储液元件100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可以用作气雾通道1303，气雾通道1303的一端与雾化室腔体9342的一端连接。
如图1a所示，气液交换元件290和雾化芯930容纳在雾化室腔体9342内，雾化室腔体9342上设置雾化室通孔9341，储液元件100中的液体通过雾化室通孔9341接触气液交换元件290并渗透其中。壳体底座112上设置导线引脚936，导线引脚936与雾化芯930通过导线933连通。可替代的，可以将气液交换元件290包覆在雾化室腔体9342外周壁上。
使用时，雾化芯930上的液体被雾化，雾化芯930上的液体含量减少时可以从气液交换元件290吸收液体，气液交换元件290则从储液元件100吸收液体，其结果是气液交换元件290将储液元件100中的液体传导给雾化芯930。随着储液元件100中的液体减少，储液元件100中的负压增加，气体透过气液交换元件290补充至储液元件100中，这一过程反复进行直至液体被用完。
在本发明中，气液交换元件290的毛细压为1mm-35mm，例如，1mm、2mm、3mm、5mm、7mm、9mm、11mm、13mm、15mm、17mm、20mm、25mm、30mm、35mm。当 气液交换元件290的毛细压小于1mm时，储液元件100中的液体容易泄漏。当气液交换元件290的毛细压大于35mm时，气体难以透过气液交换元件290补充至储液元件100，从而导致储液元件100中的负压过高，使储液元件100中的液体难以经气液交换元件290传导给雾化芯930，导致雾化芯930上液体含量不足而影响雾化质量。优选气液交换元件290的毛细压为2mm到25mm，更优选3mm-10mm。根据不同的雾化要求应选择合适的气液交换元件290的毛细压。

图2a为本发明所公开的第二实施例的一种气雾弹的纵剖面示意图；图2b为本发明所公开的第二实施例的另一种气雾弹的纵剖面示意图。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2a所示，根据本发明第三实施例的气雾弹800，包括储液元件100、雾化芯930、和连通储液元件100和雾化芯930的气液交换元件290，雾化芯930至少部分位于气液交换元件290的底部上方，气液交换元件290将储液元件100中的液体传导至雾化芯930，并且通过气液交换元件290将气体补充到将储液元件100。
在本实施例中，储液元件100为塑料制成的空腔，液体注于储液元件100中。雾化芯930为缠绕电热丝的棉纤束，棉纤束的两端穿过雾化室934的两侧的雾化室通孔9341并与雾化室通孔9341松配，以便雾化室腔体9342内的空气通过雾化室通孔9341导入气液交换元件290并最终补充到储液元件100中。气液交换元件290包覆雾化室腔体9342的外周壁上，气液交换元件290的内周壁与棉纤束的两端接触，气液交换元件290的端面接触储液元件100中的液体。
如图2a和2b所示，可以将棉纤束延伸出雾化室通孔9341的两端向上或者向下弯折后，与气液交换元件290的内周壁接触，即将棉纤束夹持在气液交换元件290和雾化室腔体9342之间。本实施例的工作原理和第一实施例相似。
在本实施例中，气液交换元件290可以是一体成型为一个整体，也可以是由多个气液交换元件290拆分成多块。在气雾弹800的空间受限时，气液交换元件290可以拆分成多块装配在气雾弹800中，例如拆分成左右两块，或者沿气雾弹800的周向拆分成三块、四块或者更多块配置。在气雾弹800的空间更小的时候，也可以仅截取部分气液交换元件290装配在气雾弹800中。
第三实施例
图3为本发明所公开的第三实施例的气雾弹的纵剖面示意图。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3所示，根据本发明第三实施例的气雾弹800，包括储液元件100、雾化芯930、和连通储液元件100和雾化芯930的气液交换元件290，雾化芯930至少部分位于气液交换元件290的底部上方，气液交换元件290将储液元件100中的液体传导至雾化芯930，并且通过气液交换元件290将气体补充到储液元件100。
储液元件100由气雾弹壳体810、气雾通道1303的壁部、雾化室腔体9342以及壳体底座112围成的空间形成。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同时用作气雾通道1303。雾化芯930设置在雾化室934内。
气液交换元件290和雾化芯930容纳在雾化室腔体9342内，雾化室腔体9342上设置雾化室通孔9341，储液元件100中的液体通过雾化室通孔9341接触气液交换元件290。即，雾化室腔体9342上设置有连通雾化室934和储液元件100的贯穿雾化室腔体9342的雾化室通孔9341。
气液交换元件290为管状的结构。气液交换元件290的外周壁与雾化室通孔9341紧配，气液交换元件290封堵雾化室通孔9341，并通过雾化室通孔9341与储液元件100中的液体接触。气液交换元件290的内周壁与雾化芯930接触，由此，将储液元件100中的液体传导至雾化芯930。
在本实施例中，气液交换元件290和雾化芯930容纳在雾化室腔体9342内，雾化芯930为缠绕电热丝的棉纤束或玻纤束。
在本实施例中，气雾弹800还包括耐高温的雾化室隔热管9343，管状的气液交换元件290具有轴向贯穿气液交换元件通孔2903，雾化室隔热管9343插入气液交换元件通孔2903内，尽可能的阻隔雾化芯930产生的热量扩散至气液交换元件290。雾化芯930的棉纤束或玻纤束缠绕电热丝的部分被置于耐高温的雾化室隔热管9343中，雾化室隔热管9343的周壁上开设有通孔，棉纤束的两端穿过该通孔与气液交换元件290接触。本实施例的工作原理与第一实施例相同。
第四实施例
图4为本发明所公开的第四实施例的气雾弹的纵剖面示意图。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4所示，根据本发明第四实施例的气雾弹800，包括储液元件100、雾化芯930、和连通储液元件100和雾化芯930的气液交换元件290，雾化芯930至少部分位于气液交 换元件290的底部上方，气液交换元件290将储液元件100中的液体传导至雾化芯930，并且通过气液交换元件290将气体补充到储液元件100。
在本实施例中，气液交换元件290由聚酰胺6纤维经增塑剂粘结形成三维网络的管状结构，并在一侧沿轴向切开。气液交换元件290的密度为0.15-0.25克/厘米 3。雾化芯930为包覆棉质不织布的螺旋状电阻丝。将气液交换元件290从切口掰开，可以通过切口装入雾化芯930，富有弹性的管状气液交换元件290回弹并闭合切口。由此，可方便地将气液交换元件290和雾化芯930一并安装于雾化室腔体9342中。
在本实施例中，导线933延伸出壳体底座112，以便于跟外部电源连接。
本实施例的工作原理与第一实施例相同。
第五实施例
图5a为本发明所公开的第五实施例的一种气雾弹的纵剖面示意图；图5b为本发明所公开的第五实施例的气液交换元件横截面示意图；图5c为本发明所公开的第五实施例的另一种气雾弹的纵剖面示意图。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，根据本发明第五实施例的气雾弹800，包括储液元件100、雾化芯930、和连通储液元件100和雾化芯930的气液交换元件290，雾化芯930至少部分位于气液交换元件290的底部上方，气液交换元件290将储液元件100中的液体传导至雾化芯930，并且通过气液交换元件290将气体补充到储液元件100。
储液元件100可以单独成型，也可以是由气雾弹壳体810和气雾通道1303的壁部围成的空间形成。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可以同时用作气雾通道1303。
储液元件100靠近壳体底座112的开口由气液交换元件290封堵。当气雾通道1303同时用作储液元件通孔130时，气雾通道1303的一端穿过部分气液交换元件290，并与气液交换元件290的内孔紧密配合，以防止液体泄漏。当储液元件100单独成型时，气液交换元件290的内孔与储液元件通孔130的壁部紧密配合，以防止液体泄漏。
当气雾弹壳体810同时用作储液元件100的壳体时，气液交换元件290的外周壁与气雾弹外壳810的内周壁紧密配合。当储液元件100单独成型时，气液交换元件290的外周壁与储液元件100的壳体的内周壁紧密配合。气液交换元件290一侧与储液元件100中的液体接触，气液交换元件290的内周壁与雾化芯930接触，由此，将储液元件100中的液体传导至雾化芯930。
如图5b所示，在本实施例中，气液交换元件290由皮芯结构的双组分纤维2经热粘结形成三维网络的立体结构，双组分纤维2的皮层21为Co-PET，芯层22为PET。气液交换元件290的横截面为圆形，中心设置轴向贯穿气液交换元件的气液交换元件通孔2903。气液交换元件290包括靠近中心的高毛细部2901和远离中心但与高毛细部2901邻接的低毛细部2902。低毛细部2902的密度为0.035-0.15克/厘米 3，高毛细部2901的密度为0.15-0.3克/厘米 3。也可以让高毛细部2901和低毛细部2902的密度相近，均在0.035-0.3克/厘米 3范围内，但用纤度较小的纤维制作高毛细部2901，用纤度较大的纤维制作低毛细部2902。低毛细部2902的毛细压为1mm-35mm，优选低毛细部2902的毛细压为2mm到25mm，更优选为3mm到10mm。可以根据不同的雾化要求选择适当毛细压的低毛细部2902。
在本实施例中，若高毛细部2901和低毛细部2902全部被液体浸润，则高毛细部2901和低毛细部2902均能传导液体，但仅低毛细部2902能传导气体。
高毛细部2901和低毛细部2902可以一体成型，也可以分体成型后装配在一起。
优选，低毛细部2902中具有缓冲空间，缓冲空间是指在正常使用过程中，低毛细部2902中存在部分未被液体浸润的部分。在这种情况下，气液交换元件290的厚度优选大于等于2毫米。本领域的技术人员可以根据气雾弹800空间的限定确定气液交换元件290的厚度，但为了确保缓冲空间的存在，气液交换元件290最低不能小于2毫米。在正常使用的情况下，若高毛细部2901被液体浸润，但低毛细部2902仅部分被液体浸润，缓冲空间不会被浸润，则高毛细部2901能传导液体，低毛细部2902能传导气体，这种情况下，未被液体浸润的部分低毛细部2902具有缓冲空间，减少液体从气雾弹泄漏的风险。在运输或者极端环境下，导致气压急剧变化时，缓冲空间可以暂存储液元件100中过量传导的液体，由此可以有效地避免液体从气雾弹800中泄漏的风险。
气液交换元件290的外周壁与气雾弹外壳的内周壁紧密配合，气液交换元件290一侧与储液元件100中的液体接触，气液交换元件290的高毛细部2901的内周壁与雾化芯930接触。使用时，储液元件100中的液体通过高毛细部2901的内周壁传导给雾化芯930。随着储液元件100中的液体导出雾化，储液元件100中的负压增加，当储液元件100与外界的压差达到一定范围时，外界空气通过气液交换元件290进入储液元件100，从而使储液元件100内的压力在雾化过程中保持稳定。本实施例的工作原理与第一实施例相似。
在本实施例中，气雾弹800还包括冷凝液吸收元件400，冷凝液吸收元件400安装在气雾通道1303中，可以吸收气雾产生的冷凝液，提高消费体验。
在本实施例中，气液交换元件290的下部延伸出储液元件100的底部开口。由于气液 交换元件290的下部延伸出储液元件100的底部开口，可以增加气液交换元件290的高度，并因此进一步提高低毛细部2902的缓冲空间的容量，由此气雾弹800的防泄漏功能可以进一步增强。
气液交换元件290的下部优选超出气雾通道1303下端部的部分的高度超过气液交换元件290高度的四分之一，更优选超过气液交换元件290高度的二分之一。气液交换元件290的下部超出气雾通道1303下端部的部分与雾化芯930接触。
使用时，储液元件100中的液体通过高毛细部2901的内周壁传导至雾化芯930。通过这种方式，可以使得气雾弹800的结构更加紧凑，装配更加方便。
如图5c所示，在本实施例中，气雾弹800包括轴向贯穿储液元件100的气雾通道1303，雾化芯930插入气雾通道1303的下端部。具体而言，可以增加雾化芯930的高度，使雾化芯930的一部分伸入气雾通道1303下端的内部。这种设置适合于使用时需要预热的气雾弹800，例如，被雾化的液体在常温下呈高粘度或半流动状，预热可以降低被雾化液体的粘度，增加流动性，提高液体通过高毛细部2901向雾化芯930传导的能力。可以用金属制成气雾通道1303，提高预热的效果。
第六实施例
图6为本发明所公开的第五实施例的气雾弹的纵剖面示意图。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6所示，根据本发明第六实施例的气雾弹800，包括储液元件100、雾化芯930、和连通储液元件100和雾化芯930的气液交换元件290，雾化芯930至少部分位于气液交换元件290的底部上方，气液交换元件290将储液元件100中的液体传导至雾化芯930，并且通过气液交换元件290将气体补充到储液元件100。
在本实施例中，气雾弹800还包括硅胶气雾管1305，硅胶气雾管105设置在气雾通道1303的下端部与雾化芯930之间。硅胶耐高温，能在通常的雾化温度下稳定使用，因此硅胶气雾管1305的使用可以降低对进入气雾通道1303中的气雾温度，可以降低气雾通道1303壁部的耐温性要求，能够扩大制造气雾弹壳体810和气雾通道1303管壁的材料选择范围。
综上，本发明涉及的气液交换元件由纤维粘结制成，能广泛应用于各类气雾弹。气雾弹中气液交换元件能平稳快速地将液体传导给雾化芯，同时补充气体到储液元件中，使储液元件内维持稳定的压力，提高雾化的稳定性。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。
