Description

一种储液元件、导液元件、冷却元件、冷凝液吸收元件及支撑元件 技术领域
本发明涉及一种储液元件、导液元件、冷却元件、冷凝液吸收元件及支撑元件，特别涉及将液体气化或雾化的气雾散发装置中储存和释放液体的储液元件、传导液体的导液元件、冷却气雾的冷却元件、吸收冷凝液的冷凝液吸收元件、及支撑风味变换部件的支撑元件。
背景技术
使用传统烟草的时候，吸入燃烧烟草时产生焦油等有害物质会影响身体健康，电子烟中，通常采用加热气化或加热雾化有效成份的方法来代替燃烧传统烟草的方法。在常见的加热液体烟油雾化的方法中，液体被储存于油仓中，雾化的气雾从油仓导出，这种结构的电子烟液体容易泄漏。也有的电子烟中采用棉花或无纺布缠绕在玻纤或陶瓷的管子上，然后将烟液注在棉花或无纺布上，由于棉花和无纺布缺乏三维立体形状和强度，难以自动化组装，并且棉花或无纺布缠绕后不均匀，局部密度较高，储液容量较小，使用后期对烟油释放能力较差，使用后液体残留率较高。电蚊香、电香薰和药物雾化吸入的装置等将液体气化或雾化的气雾散发装置中也存在类似的问题。
又，在电子烟、电蚊香、电香薰和药物雾化吸入的装置等，常见的一种结构是在气雾散发装置中安装雾化芯，如预埋电热丝的多孔陶瓷。当气流通过雾化装置的同时雾化芯加热，液体被雾化并被气流带出。为了将储液部中的液体比较平稳地传导给雾化芯并防止液体泄漏，通常在雾化芯表面包覆无纺布，并固定于气雾散发装置中。由于无纺布柔软缺少强度、容易褶皱，难以制成质量稳定的气雾散发装置，褶皱严重的情况下容易发生液体泄漏。在雾化芯表面包覆无纺布的方法需要大量人工，难以自动化，成本高、效率低。
又，传统卷烟燃烧时的温度在800℃左右，如此高温使烟草中的水分在形成气雾时，其中的大部分水被蒸发掉，气雾相对干燥，使用者吸入气雾时感知的温度较低。在不燃烧的情况下通过加热气雾基体产生的气雾或气溶胶中，可能含有较高的水分以及从气雾基体气化的气雾剂，如丙二醇、甘油等，使用者吸入气雾时感知的温度较高。未经适当冷却的加热不燃烧气雾甚至会使使用者感到烫嘴。使用加热不燃烧中药时，吸食者会遇到同样的问题。
可以在气雾基体下游采用冷却元件来吸收气雾中的热量从而冷却气雾。气雾通过热交换 把自身的热量传导给冷却元件而降低温度，冷却元件吸收气雾中的热量后温度升高，如果冷却元件中的物质在吸收热量后发生熔化等相变过程，则可以更多地吸收气雾中的热量，使气雾的降温效果更为显著。为使热交换充分进行，冷却元件需要有大的表面积与气雾接触。参考被广泛使用的翅片式热交换器，可以采用薄片状物质来制作冷却元件。CN104203015A公开了用片材制作冷却元件来冷却加热不燃烧气雾的方法。但从热交换接触面积的角度来说，薄片是二维结构，比表面积较小。此外，根据CN104203015A所公开的，用薄片制作的冷却元件不能邻接气雾基体，中间需用其他元件隔开。显然，用薄片制作的冷却元件也不能高效吸收气雾中的小液滴。综上，在气雾散发装置中薄片制作的冷却元件有诸多局限性。药物雾化吸入的装置等将液体加热气化或雾化的气雾散发装置中也存在类似的问题。
又，使用传统烟草的时候，吸入燃烧烟草时产生焦油等物质对健康危害较大，电子雾化烟采用加热雾化溶剂来摄入尼古丁或尼古丁盐，这种方法不产生焦油。电子雾化烟中的常用溶剂为1，2丙二醇和甘油，沸点分别为188.2℃和290℃，由于气雾通道的周壁温度较低，雾化后的气雾通过气雾通道的过程中冷凝液不断增加。大量的冷凝液进入口中时会严重影响使用者的口感，因此在气雾入口前去除大部分冷凝液能大幅度提升电子雾化烟的吸烟体验。可使用适当的吸收物质(冷凝液吸收元件)与冷凝液接触来去除冷凝液。有的雾化装置中，冷凝液会沉降到雾化器底部，这种情况下可以在雾化器底部安装冷凝液吸收体来防止冷凝液渗入主机。较为常见冷凝液吸收元件由多层无纺布叠加在一起并模切成要求的大小和形状，由于无纺布柔软、并缺乏固定的立体形状，在狭小的电子雾化气雾雾通道中安装或固定困难。另一种较为常见的冷凝液吸收元件由纤维或木浆压缩成片状，根据需要切成要求的大小和形状，或根据需要冲孔形成气流通道，这种冷凝液吸收元件俗称高压棉。其优点是可以制成立体形状，便于安装，高压棉的缺点是吸收冷凝液后明显膨胀，使用过程中气雾通道的气阻不稳定，影响使用体验。药物雾化吸入的装置等将液体气化或雾化的散发装置中也存在类似的问题。
又，对传统烟草，吸入燃烧烟草时产生的焦油等有害物质，对健康影响较大。通过雾化来摄入尼古丁或尼古丁盐，因为这种方法不产生焦油等有害物质，应用越来越广泛。类似的雾化技术也可用于摄入药物等物质。为提升口感，通常在被雾化的液体中加入各种风味剂。但有两个问题，一方面风味剂容易挥发，在产品储存过程中会逐渐失去风味，另一方面，风味剂在加热雾化时可能因高温而分解或产生有害物质，从而产生额外的安全风险。
发明内容

由双组分纤维经热粘结制成的具有三维网络的立体结构的储液元件，可以方便地在气雾散发装置中组装。这种储液元件密度较低、孔隙率较高，因此单位体积内可以储存更多的液体，并能将液体更高效地释放，由于液体被储存于储液元件的毛细空隙中，在储运和使用过程中不易泄漏。本发明的储液元件不但可以用于电子烟，也适用于具有雾化器的电蚊香、电香薰和药物雾化装置中。

由双组分纤维粘结制成的冷却元件比表面积大，有利于提高与气雾的热交换效率。双组分纤维的芯层熔点比皮层熔点高25℃以上，当气雾温度高于皮层熔点时，皮层接触高温气雾被部分熔化并吸收大量热量，使气雾温度迅速降低。双组分纤维中的高熔点芯层担当骨架，熔化的皮层成为黏流态并附着于芯层上，从而保持冷却元件的完整性。
由双组分纤维粘结制成的冷却元件，可以根据要求制成不同的孔隙率，使冷却元件具有需要的径向硬度和轴向刚性，便于和气雾基体等其它元件装配成气雾散发装置，容易实现高效的自动化装配。

本发明的冷凝液吸收元件由双组分纤维粘结制成，具有三维网络的立体结构，能在接触气雾时快速吸收气雾周边的冷凝液，并传导至冷凝液吸收元件的各部位，对气雾中的冷凝液去除效率高，用户体验好。本发明的冷凝液吸收元件具有较低的密度和较高的孔隙率，单位体积的吸收容量大，适合于气雾散发装置的紧凑空间。
本发明的冷凝液吸收元件，由双组分纤维粘结制成的三维网络立体结构，吸收冷凝液后不膨胀、不变形，使气雾通道具有稳定的气流阻力，有利于保持气雾散发装置使用过程中的气阻稳定性，提升用户体验。
制成本发明的冷凝液吸收元件的双组分纤维的皮层可以为聚乳酸，聚乳酸为生物降解材料，可以减少冷凝液吸收元件被抛弃时造成的环境污染。尤其是当双组分纤维的芯层也为聚乳酸时，被抛弃的冷凝液吸收元件可以在自然界中被微生物完全降解生成二氧化碳和水。
本发明还提出了一种支撑元件，用于气雾散发装置中支撑风味变换部件，该支撑元件由双组分纤维经热粘结形成三维网络的立体结构，该双组分纤维具有皮层和芯层。

第一实施例
图1a为本发明所公开的第一实施例的储液元件的纵剖面图；图1b为本发明所公开的第一实施例的储液元件的横截面图。
如图1a和1b所示，根据本发明第一实施例的储液元件，用于气雾散发装置中储存和释放液体，储液元件100由双组分纤维2经热粘结形成三维网络的立体结构，双组分纤维2具有皮层21和芯层22。
<储液元件的形状>
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可以用作气雾散发装置中的气雾通道。
本实施例的储液元件100可以根据气雾散发装置的内部空间制成合适的几何形状，如适合于圆柱形气雾散发装置的圆柱形储液元件100；适合于扁形气雾散发装置的方柱形储液元件100；适合于椭圆柱形气雾散发装置的椭圆柱形储液元件100等。
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中可以插入气雾管，如金属管、玻纤管或塑料管等，气雾可以从气雾管导出。设置气雾管可以更好地固定储液元件100，并可以在储液元件100注液时防止液体从雾化器(未图示)泄漏。
可以将储液元件100与雾化器接触的部位压缩成较高密度，使液体在释放过程中向较高密度部位富集，从而提高液体释放的均匀性，并进一步降低使用后的液体残留。
<储液元件的密度>
本实施例的储液元件100密度为0.03-0.25克/厘米 3，如0.03克/厘米 3、0.04克/厘米 3、0.050克/厘米 3、0.055克/厘米 3、0.065克/厘米 3、0.08克/厘米 3、0.10克/厘米 3、0.12克/厘米 3、0.15克/厘米 3、0.18克/厘米 3、0.21克/厘米 3、0.25克/厘米 3，优选为0.04-0.12克/厘米 3。当密度小于0.03克/厘米 3时，储液元件100制造困难，并且储液元件100的强度不足，不易在气雾散发装置中组装；当密度为0.03-0.04克/厘米 3时，轴向设置通道的储液元件100的 强度稍嫌不足，不太易组装；当密度大于0.15克/厘米 3时，使用后期储液元件100的液体释放效率略差，使用后的液体残留偏高；当密度大于0.25克/厘米 3时，单位体积储液元件100的储液量过小，并且使用后期储液元件100的液体释放效率差，使用后的液体残留高，不利于在空间狭小的气雾散发装置中使用。
在0.04-0.12克/厘米 3范围内，根据被储存液体的粘度、表面张力和应用需求，选择合适的密度，储液元件100既有足够的毛细力以防止液体泄漏，又具有良好的释放性能，并且可以使储液元件100的储液容量最大化，有利于制作小巧的气雾散发装置。值得注意的是，为防止在储存、运输和使用过程中泄漏，加载到储液元件100的液体体积最好不超过储液元件100中毛细空隙体积的90％。
为更直观地说明储液元件100的密度与使用效果的关系，本实施例制作了不同密度的储液元件100并组装了相应的气雾散发装置进行抽吸测试。雾化芯为缠绕电热丝的玻纤束。储液元件100由3旦的双组分短纤热粘结制成，皮层21为聚乙烯，芯层22为聚丙烯，储液元件100的高度为29mm，体积为1.91厘米 3。储液元件100的密度分别为0.04克/厘米 3，0.055克/厘米 3，0.08克/厘米 3，0.12克/厘米 3，0.15克/厘米 3，和0.20克/厘米 3，被雾化的液体为丙二醇和甘油的混合物，注液量为1.62克。用抽烟机进行测试，测试条件为：吸气3秒，停27秒，每分钟吸气2次，每次吸气55ml，收集每抽吸50口的雾化量，每个产品重复测试20次，锂电池设计容量为400口(实际测试405-436口时电池耗尽)。数据经计算后获得每口雾化量的平均值(单位mg)、变异系数(简称CV)，以及抽吸400口后的液体残留率和变异系数，结果如下：
Figure PCTCN2020116733-appb-000001
从测试结果可以看出，0.04-0.20克/厘米 3的密度范围内，储液元件100的密度越小，抽吸过程中雾化量的衰减越小。特别是当密度为0.04-0.12克/厘米 3时，前350口的雾化量相当稳定。而当密度为0.20克/厘米 3时，即使前350口雾化量也存在明显衰减。一般认为抽吸过 程中雾化量衰减越小，口感越稳定，用户体验越好。实验数据也显示，351-400口时雾化量衰减较多，并且CV明显偏大，这一般认为是由于锂电池即将耗尽时电压不稳定所导致。
当储液元件100的密度为0.15克/厘米 3时，301-350口的雾化量比1-50口的雾化量衰减了33.3％，351-400口的雾化量比1-50口的雾化量衰减了41.2％；当储液元件100的密度为0.20克/厘米 3时，301-350口的雾化量比1-50口的雾化量衰减了44.5％，351-400口的雾化量比1-50口的雾化量衰减了50.6％。在抽吸过程中，当雾化量比初始抽吸阶段降低接近50％时，一般被认为明显影响口感。
由于毛细力的作用，抽吸结束后储液元件100中会残留一部分液体。液体的残留率越低，则液体的利用效率越高。从测试结果可以看出，0.04-0.20克/厘米 3的密度范围内，储液元件100的密度越小，抽吸400口后液体的残留率越低。当储液元件100的密度为0.04-0.12克/厘米 3时，抽吸400口后液体的残留率低于介于16.5％-24.2％；当储液元件100的密度为0.15克/厘米 3时，抽吸400口后液体的残留率接近30％；当储液元件100的密度为0.20克/厘米 3时，抽吸400口后液体的残留率超过35％，液体的利用效率不到65％，浪费较为严重。
综合考虑抽吸过程中雾化量的稳定性和抽吸后的液体残留率，以及组装的方便性，本发明确定储液元件100优选的密度范围为0.03-0.15克/厘米 3，最优选为0.04-0.12克/厘米 3。
<双组分纤维>
如图1a和1b所示，根据本实施例的储液元件100由双组分纤维2粘结形成三维网络的立体结构，双组分纤维2具有皮层21和芯层22。可以采用粘结剂、增塑剂或热量粘结纤维，优选用热量来粘结纤维以避免在制作储液元件100的过程中引进杂质。本发明中所说的纤维组分是指制作纤维的聚合物。用于纤维表面的添加剂，如表面活性剂，并不被认为是纤维的组分。本实施例的储液元件100能被储存的液体浸润，可以添加表面活性剂来改变储液元件100被液体浸润的能力。
图1c是图1a和1b中的双组分纤维的一种截面放大示意图。如图1c所示，皮层21和芯层22为同心结构。同心结构的双组分纤维2刚性较大，生产方便，价格较低。
图1d是图1a和1b中的双组分纤维的另一种放大截面示意图。如图1d所示，皮层21和芯层22为偏心结构。偏心结构的双组分纤维2较为柔软蓬松，容易制作密度较小的储液元件100。此外，还可以采用并列结构的双组分纤维来制作储液元件100，但热粘结时比较困难。当然，还可以采用三组分的皮芯结构纤维来制作储液元件100，但三组分的皮芯结构纤维制造难度大，成本高，性价比较差。
双组分纤维2为长丝或者短纤。长丝制成的储液元件100强度较高，短纤制成的储液元 件100弹性较好。制造者可以根据储液元件100的性能要求选择合适的双组分纤维制成合适的密度和合适形状的储液元件100。
双组分纤维2的芯层22比皮层21的熔点高25℃以上。本实施例的储液元件100由皮芯结构双组分纤维2热粘结制成。双组分纤维2的芯层22比皮层21熔点高25℃以上，可以在纤维之间进行热粘结的时候使芯层22保持一定的刚性，便于制成密度较低的储液元件100。
皮层21为聚乙烯、聚丙烯、聚烯烃、或者共聚酯，所述芯层22为聚合物。或者，皮层21为聚乳酸，芯层22为熔点比皮层21高25℃以上的聚乳酸。
双组分纤维2的皮层21可以为聚乙烯、聚丙烯、聚对苯二甲酸乙二醇酯的共聚酯、聚酰胺-6和聚乳酸等常见的聚合物，或者其它聚烯烃。聚烯烃为烯烃的聚合物，通常由乙烯、丙烯、1-丁烯、1-戊烯、1-己烯等α-烯烃单独聚合或共聚而得的一类热塑性树脂的总称。聚烯烃具有惰性的分子结构，分子链上不含活性基团，在本发明的应用领域中几乎不与液体成分反应，因此具有独特的优势。
当皮层21为聚乙烯时，比如线性低密度聚乙烯、低密度聚乙烯或高密度聚乙烯，芯层22可以为聚丙烯、聚对苯二甲酸乙二酯等聚合物。当皮层21为聚丙烯和聚烯烃时，芯层22可以为聚对苯二甲酸乙二酯(简称PET)、聚对苯二甲酸丙二醇酯(简称PTT)或聚对苯二甲酸丁二醇酯(简称PBT)、聚酰胺等。双组分纤维2的皮层21熔化温度低，有利于提高生产效率，降低制造过程中的能耗。
当皮层21为聚乳酸时，根据聚乳酸的熔点，如果采用熔点约130℃的聚乳酸为皮层21，芯层22可以为聚丙烯、聚对苯二甲酸乙二酯、熔点约170℃左右的聚乳酸等。当皮层21为熔点约170℃的聚乳酸时，芯层22可以为聚对苯二甲酸乙二酯、聚对苯二甲酸丁二酯、聚对苯二甲酸丙二酯、尼龙、聚酰胺等。聚乳酸为生物降解材料，可以减少储液元件100被抛弃时造成的环境污染。尤其是当皮层21采用较低熔点的聚乳酸，芯层22采用较高熔点的聚乳酸时，制成的储液元件100为生物全降解材料。
<双组分纤维的纤度>
制作本发明储液元件100的双组分纤维2的纤度介于1-30旦，优选1-15旦，最优选1.5-10旦。低于1旦的皮芯结构双组分纤维2制造困难，成本高。高于30旦的纤维制成的储液元件100毛细力不足，容易泄漏。介于1-15旦的皮芯结构双组分纤维2容易热粘结成密度较低、并且具有合适毛细力的三维立体结构的储液元件100，1.5-10旦皮芯结构双组分纤维2尤为合适，并且成本较低。
可以将不同纤度的双组分纤维混合制成储液元件100，以优化储存和释放液体的性能或者降低成本。还可以在不影响储液元件100加工和性能的情况下在双组分纤维中掺入一些单组份纤维如聚丙烯纤维等来降低成本。
本实施例中，优选双组分纤维2的纤度为1.5旦、2旦、3旦或6旦，皮层21为熔点约130℃的聚乙烯，芯层22为熔点约165℃的聚丙烯，储液元件100密度介于0.04-0.12克/厘米 3，储液元件100具有储液容量大、不易泄漏和释放效率高等优点。
虽然储液元件100也可以由单组份纤维，如聚丙烯纤维，用粘结剂粘结制成，但粘结剂的使用通常会使储液元件100难以符合食品或药品的相关法规，这种储液元件100不宜用于电子烟、药物雾化等气雾散发装置中。
如图1a、1b、1c和1d所示，在本实施例中，储液元件100由同心结构或偏心结构的双组分纤维2经热粘结形成三维网络的立体结构。储液元件100形状为圆柱体，外径为9mm，并设置直径为3.5mm的轴向通孔为储液元件通孔130，通孔的一端与雾化器连接并将液体传导给雾化器。这种储液元件100的形状和尺寸适合于仿真烟形状的电子烟中使用，也适合在迷你型电蚊香和香薰中使用。本实施例中双组分纤维2的皮层21可以用熔点约130℃的聚乳酸代替，制成的储液元件100具有类似的性能。

如图2a和2b所示，本实施例中，储液元件100由同心结构的双组分长丝经热粘结形成三维网络的立体结构，双组分纤维2的纤度为6旦，皮层21为熔点约165℃的聚丙烯，芯层22为熔点230℃左右的聚对苯二甲酸丁二酯，这种储液元件100具有较高的耐温性能，制成的储液元件100密度介于0.1-0.2克/厘米 3，具有较大的刚性，适合于高速自动化组装。储液元件100横截面图显示的形状为长方体，设置直径3mm的轴向通孔为储液元件通孔130，通孔的一端与雾化器连接，雾化时产生的气雾经储液元件通孔130逸出，这种储液元件100的形状适合在长方体形状的扁烟中使用，也适合于电蚊香和电加热香薰中使用。本实施例中双组分纤维2的皮层21可以用熔点约170℃的聚乳酸代替，制成的储液元件100具有类似的性能。
第三实施例

如图3a和3b所示，本实施例中，储液元件100由同心结构的双组分纤维2经热粘结形成三维网络的立体结构，双组分纤维2为短纤，其纤度为2旦，皮层21为熔点130℃的聚乳酸，芯层22为熔点155-185℃的聚乳酸，制成的储液元件100密度介于0.08-0.12克/厘米 3。储液元件100横截面图显示的为椭圆形，设置直径为4mm的轴向通孔为储液元件通孔130，通孔的一端与雾化器连接，储液元件100中的液体经连接处传导给雾化器，雾化时产生的气雾经储液元件通孔130逸出，这种储液元件100的形状适合在椭圆柱形状的扁烟中使用，也可用于类似形状的电蚊香和电香薰。本实施例中的储液元件100完全由聚乳酸制成，能完全生物降解，对减少环境污染具有重要意义。
第四实施例

如图4a和4b所示，本实施例中，储液元件100由偏心结构的双组分纤维2经热粘结形成三维网络的立体结构，双组分纤维2为短纤，其纤度为3旦，皮层21为熔点约130℃的聚乳酸，芯层22为聚对苯二甲酸乙二酯。制成的储液元件100密度介于0.03-0.06克/厘米 3，具有吸液容量大和释放残留低的特性。储液元件100为圆柱形，设置直径为4.5mm的轴向通孔为储液元件通孔130，通孔的一端与雾化器连接，雾化时产生的气雾经储液元件通孔130逸出。
本实施例中与雾化器连接部位的储液元件100被压缩形成较高密度，液体在消耗的过程中向较高密度部位富集，从而提高液体释放的均匀性并进一步降低使用后的液体残留。
优选，储液元件100被压缩形成低密度部123和高密度部124和设置在低密度部123和高密度部124之间的密度递增部125。从而液体能够更好的向高密度部124富集，可以提高液体传导的流畅性，并减少使用后在储液元件100中的液体残留。
这种储液元件100的形状适合在圆柱形的电子烟中使用，也适合用于电蚊香和电香薰。本实施例中双组分纤维2的皮层21可以用聚烯烃或熔点约110℃的聚对苯二甲酸乙二醇酯的共聚酯代替，制成的储液元件100具有类似的性能。
第五实施例
图5a为本发明所公开的第五实施例的储液元件100的纵剖面图；图5b为本发明所公开的第五实施例的储液元件100的横截面图。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和5b所示，本实施例中，储液元件100由同心结构的双组分纤维2经热粘结形成三维网络的立体结构，双组分纤维2为长丝，其纤度为30旦，皮层21为熔点约200℃的聚对苯二甲酸乙二醇酯的共聚酯，芯层22为熔点270℃左右的聚对苯二甲酸乙二酯，这种储液元件100具有较高的耐温性能，制成的储液元件100密度介于0.15-0.25克/厘米 3，储液元件100为圆柱形，设置直径5mm的轴向通孔为储液元件通孔130，通孔的一端与电加热雾化器或超声波雾化器连接，雾化时产生的气雾经储液元件通孔130逸出，这种储液元件100适合于便携式电蚊香或香薰中使用，也适合用于电子烟。本实施例中双组分纤维2的皮层21可以用熔点约170℃的聚乳酸代替，制成的储液元件100具有类似的性能。
第六实施例
图6a为本发明所公开的第六实施例的储液元件100的纵剖面图；图6b为本发明所公开的第六实施例的储液元件100的横截面图。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6a和6b所示，本实施例中，储液元件100包括上下结构的储液部121和集液部122。储液部121和集液部122均具有轴向贯穿的储液元件通孔130。
储液部121由偏心结构的双组分纤维2经热粘结形成三维网络的立体结构，双组分纤维2的纤度为3旦，皮层21为熔点约130℃的聚乙烯，芯层22为熔点165℃左右的聚丙烯，储液部121密度介于0.04-0.08克/厘米 3，储液部121为圆柱形。制成集液部122的双组分纤维2与制成储液部的纤维相同，储液部121和集液部122均设置直径4mm的轴向通孔为储液元件通孔130，通孔的一端与电加热雾化器或超声波雾化器连接，雾化时产生的气雾经储液元件通孔130逸出，这种储液元件100适合于便携式电蚊香或香薰中使用，也适合用于电子烟。本实施例中双组分纤维2的皮层21可以用熔点约130℃的聚乳酸代替，制成的储液元件100具有类似的性能。
本实施例中，集液部122的密度高于储液部121。由于集液部122的密度高于储液部121，使液体在消耗的过程中向较高密度的集液部122富集，从而提高液体释放的均匀性并进一步降低使用后的液体残留。
第七实施例
图7a为本发明所公开的第七实施例的储液元件100的纵剖面图；图7b为本发明所公开的第七实施例的储液元件100的横截面图。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和7b所示，本实施例中，储液元件100包括集液部122和包覆在集液部122外周壁上的密度低于集液部122的储液部121。集液部122具有轴向贯穿集液部122的储液元件通孔130。
储液部121由同心结构的双组分纤维2经热粘结形成三维网络的立体结构，双组分纤维2的纤度为3旦，皮层21为熔点约130℃的聚乳酸，芯层22为熔点270℃左右的聚对苯二甲酸乙二酯，储液部121密度介于0.1-0.15克/厘米 3，储液部121为圆柱形。集液部122由同心结构的双组分纤维2经热粘结形成三维网络的立体结构，双组分纤维2的纤度为2旦，皮层为熔点约170℃的聚乳酸，芯层为熔点270℃左右的聚对苯二甲酸乙二酯，设置直径5mm的轴向通孔为气雾通道，通孔的一端与电加热雾化器或超声波雾化器连接，雾化时产生的气雾经储液元件通孔130逸出，这种储液元件100适合于便携式电蚊香或香薰中使用，也适合用于电子烟。
本实施例中，集液部122的密度高于储液部121。由于集液部122的密度高于储液部121，使液体在消耗的过程中向较高密度的集液部122富集，从而提高液体释放的均匀性并进一步降低使用后的液体残留。
综上，本发明涉及的用于气雾散发装置的储液元件100采用了皮芯结构的双组分纤维制成并在轴向设置气雾通道，气雾通道由储液元件100中的储液元件通孔130形成。本发明的储液元件100能广泛应用于各类将液体气化或雾化的气雾散发装置中来储存和释放液体，在简化气雾散发装置结构的同时巧妙地具有导出气雾的功能，提高使用者体验。储液元件100根据应用需求能在热粘结过程中制成需要的三维结构的尺寸和形状，从而适合高速的自动化组装，以降低电子烟、药物雾化、电蚊香和电香薰等气雾散发装置的制造成本。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。
第八实施例
图8a为本发明所公开的第八实施例的导液元件的纵剖面图；图8b为本发明所公开的第 八实施例的导液元件的横截面图；图8c是图8a和8b中的双组分纤维的一种截面放大示意图；图8d是图8a和8b中的双组分纤维的另一种截面放大示意图。
如图8a至8d所示，根据本发明第八实施例的导液元件200，用于气雾散发装置中传导液体，导液元件200由双组分纤维2经热粘结形成三维网络的立体结构，双组分纤维2具有皮层21和芯层22。
<导液元件的形状、厚度、刚性和液体渗透的速度>
导液元件200可以具有轴向贯穿导液元件200的导液元件通孔230。
本实施例的导液元件200，根据气雾散发装置的设计，可以把导液元件200设计为片状或者管状。如图1a和图1b所示，本实施例中的导液元件200设置为管状。
导液元件200也可以设计为片状。片状的导液元件200也可以设置导液元件通孔230。
根据气雾散发装置的结构，可以把导液元件200的横截面制成圆环状、椭圆环状或其它需要的形状。
对于片状导液元件200，本文中轴向定义为其厚度方向，径向定义为与厚度垂直的方向。采用适当的制作技术，可以使纤维在导液元件200中具有较多的轴向排列取向，这种情况下，片状导液元件200的轴向刚性大于其径向刚性，导液元件200中液体沿轴向渗透的速度大于液体沿径向渗透的速度；也可以使纤维在导液元件200中具有较多的径向排列的取向，这种情况下，片状导液元件200的径向刚性大于其轴向刚性，导液元件200中液体沿径向渗透的速度大于液体沿轴向渗透的速度。
对管状导液元件200，本文中轴向定义为导液元件通孔230的中轴线的方向，径向定义为与导液元件通孔230的中轴线垂直的方向。管状导液元件200中纤维具有较多的轴向排列取向，导液元件200的轴向刚性大于其径向刚性，导液元件200中液体沿轴向渗透的速度大于液体沿径向渗透的速度。
本文中的刚性的比较方法是：将导液元件200沿轴向或者径向放置，夹持在两块平行的板之间，测量未压缩前的导液元件200的轴向高度或者径向高度；在施加同样作用力的情况下，测量两块板轴向或者径向压缩导液元件200后的轴向高度或者径向高度，并计算压缩的变形量，该压缩的变形量为未压缩前的轴向高度或者径向高度减去压缩后的轴向高度或者径向高度后的差值；将压缩的变形量除以未压缩前的导液元件200的轴向高度或者径向高度，获得压缩比。压缩比越小，则刚性越大，压缩比越大，则刚性越小。
导液元件200的厚度是指液体从导液元件200一侧传导到另一侧的最短距离，管状导液元件200的厚度为管壁的厚度，片状导液元件200的厚度为其厚度方向上的厚度。
导液元件200的厚度为0.3mm-3mm，优选0.6mm，0.9mm，1.2mm，1.5mm，2mm。当导液元件200的厚度小于0.3mm时，难以制作均匀的导液元件200，也不方便安装。当导液元件200的厚度大于3mm时，导液元件200在气雾散发装置中占过多的空间，尤其对管状导液元件200，厚度大于3mm时通常难以在细小的气雾散发装置中安装。另外，厚度大于3mm时，导液元件200吸收液体量过多，影响液体的利用效率。
<导液元件的密度>
本实施例的导液元件200的密度为0.05-0.35克/厘米 3，优选为0.1-0.3克/厘米 3。当密度小于0.05克/厘米 3时，导液元件200的强度不足，管状导液元件200与气雾散发装置装配时容易变形甚至褶皱，影响雾化的稳定性，严重时甚至造成漏液。当密度大于0.35克/厘米 3时，导液速度较慢，影响雾化效率，并且高密度的导液元件的硬度过高，径向弹性不足，管状导液元件与气雾散发装置的匹配性下降。
<双组分纤维>
图8c是图8a和8b中的双组分纤维的一种放大截面示意图。如图8c所示，皮层21和芯层22为同心结构。图8d是图8a和8b中的双组分纤维的另一种放大截面示意图。如图8d所示，皮层21和芯层22为偏心结构。由同心结构的双组分纤维2制成的导液元件刚性较大，由偏心结构的双组分纤维2制成的导液元件200弹性较好。
双组分纤维2为长丝或者短纤。长丝制成的导液元件200刚性较大，短纤制成的导液元件200弹性较好。可以根据导液元件200的性能要求选择双组分纤维制成合适的导液元件200。
双组分纤维2的芯层22比皮层21的熔点高20℃以上。本实施例的导液元件200由皮芯结构双组分纤维2热粘结制成。双组分纤维2的芯层22比皮层21熔点高20℃以上，可以在纤维之间进行热粘结的时候使芯层22保持一定的刚性，便于制成空隙均匀的导液元件200。
双组分纤维2的皮层21可以为聚烯烃、聚对苯二甲酸乙二醇酯的共聚酯、聚对苯二甲酸丙二醇酯、聚对苯二甲酸丁二醇酯、聚乳酸或者聚酰胺-6。聚烯烃为烯烃的聚合物，通常由乙烯、丙烯、1-丁烯、1-戊烯、1-己烯等α-烯烃单独聚合或共聚而得的一类热塑性树脂的总称。也可以为聚酯或低熔点共聚酯等常见的聚合物。
当皮层21为聚乙烯时，芯层22可以为聚丙烯、聚对苯二甲酸乙二醇酯(简称PET)等聚合物。当皮层21为聚丙烯时，芯层22可以为PET、聚酰胺等。双组分纤维2的皮层21熔点较低，有利于提高生产效率，降低制造成本。双组分纤维2的皮层21熔点较高，导液元件有较高的耐温性能，有利于提高雾化芯的工作温度。
当皮层21为聚乳酸时，根据聚乳酸的熔点，比如用熔点125-135℃的聚D，L-乳酸为皮层21，芯层22可以为聚丙烯、聚对苯二甲酸乙二醇酯、熔点155-180℃的聚L-乳酸或聚D-乳酸等。当皮层21为熔点145-180℃的聚D-乳酸或聚L-乳酸时，芯层22可以为聚对苯二甲酸乙二醇酯、聚对苯二甲酸丁二醇酯(简称PBT)、聚对苯二甲酸丙二醇酯(简称PTT)、聚酰胺等。聚乳酸为生物降解材料，可以减少导液元件被抛弃时造成的环境污染。
当皮层21为聚酯或共聚酯时，可以根据皮层21的熔点选择合适的芯层22。比如皮层21用熔点225-235℃的PBT或PTT，芯层22可以用熔点255-265℃的PET。再比如皮层为熔点为110-120℃或160-200℃的聚对苯二甲酸乙二醇酯的共聚酯(简称Co-PET)，芯层可以用PET、PBT或PTT。
制作本发明导液元件200的双组分纤维2的纤度介于1-30旦，优选1.5-10旦。低于1旦的皮芯结构双组分纤维2制造困难，成本高。高于30旦的纤维制成的导液元件200毛细力不足，导液较差。介于1-30旦的皮芯结构双组分纤维2容易制作导液元件200，1.5-10旦皮芯结构双组分纤维2尤为合适，并且成本较低。被雾化的液体粘度较低时，宜采用纤度较小的纤维制作导液元件，如采用1旦、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导液元件，如采用6旦、10旦、30旦的纤维。
如图8a、8b、8c和8d所示，在本实施例中，优选导液元件200由同心结构的双组分短维2经热粘结形成三维网络的管状立体结构。皮层21为熔点125-135℃的聚乙烯，芯层22为熔点160-170℃的聚丙烯，制成的导液元件200密度介于0.05-0.35克/厘米 3，这种导液元件200具有较好的轴向强度和较好的径向弹性，并具有较快的液体传导速度。这种导液元件200可以用于电子烟烟液的雾化，也适合在迷你型电蚊香和香薰中使用。
本实施例中双组分纤维2的皮层21用熔点160-170℃的聚丙烯替代时，双组分纤维2的芯层可以用PET、PBT、PTT、聚酰胺等，制成的导液元件200具有较高的耐温性能。还可以用PBT或PTT作为皮层，用PET为芯层制成耐温更高的导液元件200。
在本实施例中的另一优选方式中，导液元件200由偏心结构的双组分纤维经热粘结形成三维网络的管状结构。导液元件200的皮层21为聚乙烯，芯层22为聚丙烯或PET，制成的导液元件200厚度为0.3-0.8mm，密度介于0.1-0.3克/厘米 3。

本实施例中，片状导液元件200的径向刚性大于其轴向刚性，导液元件200中液体沿径向渗透的速度大于液体沿轴向渗透的速度。
如图9b、9c和9d所示，根据气雾散发装置的结构，可以把导液元件200分别设计为圆柱体、方柱体和椭圆柱体，对应的横截面分别为圆环状、方形环状、椭圆环状。也可以根据需要设计为其它需要的形状。

在本实施例中，导液元件200为片状，中心不设置导液元件通孔230，且由偏心结构的双组分纤维2经热粘结形成三维网络的结构。皮层21为熔点145-180℃的聚D-乳酸或聚L-乳酸，芯层22为熔点255-265℃的PET，制成的导液元件200密度介于0.25-0.35克/厘米 3，厚度为3mm。这种导液元件200具有较高的导液速度。本实施例中双组分纤维的皮层可以用Co-PET代替以降低成本，或用PBT或PTT代替，使导液元件200具有更好的耐温性能。
在本实施例中，导液元件200的轴向刚性大于其径向刚性，导液元件200中液体沿轴向渗透的速度大于液体沿径向渗透的速度。
本实施例中,也可以是，导液元件200由同心结构的双组分纤维经热粘结形成三维网络的片状结构，厚度为1.5-2mm。导液元件的皮层21为PBT或PTT，芯层22为PET，制成的导液元件200密度介于0.25-0.35克/厘米 3。优选，该片状导液元件的径向刚性大于其轴向刚性，导液元件中液体沿径向渗透的速度大于液体沿轴向渗透的速度。

综上，本发明涉及的用于气雾散发装置的导液元件由双组分纤维粘结制成，能广泛应用于各类气雾散发装置。导液元件具有较好的强度，适合自动化组装，大幅提高气雾散发装置的生产效率。导液元件能平稳快速地将液体传导给雾化芯，提高雾化效率和稳定性。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。
第十一实施例
图11a是根据本发明第十一实施例的冷却元件的纵剖面图；图11b是根据本发明第十一实施例的冷却元件的一种横截面图；图11c是图11a和11b中的双组分纤维的一种截面放大示意图；图11d是图11a和11b中的双组分纤维的另一种截面放大示意图；图11e是根据本发明第十一实施例的冷却元件的另一种横截面图。
如图11a至图11e所示，根据本发明第十一实施例的冷却元件，用于冷却气雾散发装置中产生的气雾，冷却元件300由双组分纤维2经热粘结形成三维网络的立体结构，双组分纤维材料2具有皮层21和芯层22。
本实施例适用于各种气雾散发装置，如加热不燃烧型的气雾散发装置和雾化型的气雾散发装置。气雾散发装置中包括气雾基体，气雾基体中含有气雾剂，如丙二醇、甘油、水等。气雾基体还可以包括载体，如烟草、中草药、纤维、纸屑等等。传统的卷烟燃烧时高达800℃左右的温度将烟草中的大部分水分蒸发掉，气雾相对干燥，使用者吸入气雾时感知的温度较低。不同的是，气雾散发装置加热时的温度较低，只有200-400℃，产生的气雾中可能含有较高的水分，并含有气化的气雾剂，如丙二醇、甘油等，使用者吸入这种气雾时感知的温度较高。因此将气雾冷却至使用者感觉舒服的温度并去除冷凝液是气雾散发装置的一个重要考量。
在雾化类的气雾散发装置中，气雾基体也可以为加载气雾剂的储液元件。在此种情形下，气雾基体891中的气雾剂通过加热元件(未图示)加热后雾化并通过冷却元件300冷却后逸出。同时，冷却元件300兼具吸收气雾中的冷凝液的功能，使得使用者吸入气雾时感知的温度适中，且基本不包含冷凝液，提升口感和体验。
<冷却元件的孔隙率>
根据本实施例的冷却元件300由双组分纤维热粘结制成，可以制成不同的孔隙率。在本实施例中，冷却元件300的孔隙率可以设置为65％-95％，优选孔隙率为75-85％。
孔隙率大于95％时，冷却元件300成型困难并且硬度不足。孔隙率小于65％时，冷却元件300硬度过大，或成本过高，不适合在气雾散发装置中使用。
<冷却元件的结构>
根据本实施例的冷却元件300，可以根据需要制成各种结构，如图11a至11c所示，冷却元件300可以设置为中空的结构，即冷却元件300可以具有轴向贯穿冷却元件300的冷却元件通孔330。
如图11b所示，冷却元件300可以设置为冷却元件通孔330截面为圆形的中空结构，冷却元件300的横截面形状为圆环。也可以如图11e所示，冷却元件300可以设置为冷却元件通孔330截面为星形的中空结构，冷却元件300的横截面形状为星形环，冷却元件通孔330的截面可以为五角星形、六角星形等。
在制作冷却元件300时，中空的冷却元件300和非中空的冷却元件300可以单独使用，也可以组合使用，以达到适当的冷却效果并控制合适的气阻。
本实施例中，采用中空结构的冷却元件300，可以降低气雾穿过冷却元件300的阻力，从而使高温气雾在气阻低的中空通道通过，中空通道内表面与高温气雾接触时，双组分纤维2的皮层21从高温气雾中吸收大量热量而熔化，使气雾温度迅速降低。当高温气雾主要从中空通道通过时，冷却元件300的外周与高温气雾距离较远，温度传递至外周时已经降至较低温度，从而避免冷却元件300的外周壁因高温而发生形变或损坏气雾散发装置的结构和性能。
<双组分纤维>
如图11c和11d所示，本发明的冷却元件300由双组分纤维2经热粘结形成三维网络的立体结构，双组分纤维2具有皮层21和芯层22。
图11c是图11a和11b中的双组分纤维的一种截面放大示意图。如图11c所示，皮层21和芯层22为同心结构。图11d是图11a和11b中的双组分纤维的另一种截面放大示意图，如图11d所示，皮层21和芯层22为偏心结构。密度相同时，由同心结构的双组分纤维2制成的冷却元件300刚性较大，由偏心结构的双组分纤维2制成的冷却元件300弹性较好。
双组分纤维2为长丝或者短纤。长丝制成的冷却元件300轴向刚性较大，短纤制成的冷却元件300径向弹性较好。可以根据冷却元件300的性能要求选择双组分纤维制成合适的冷却元件300。
双组分纤维2的皮层21可以为聚乙烯、聚丙烯等聚烯烃、或对苯二甲酸乙二醇酯的共聚酯、聚对苯二甲酸丙二酯、聚对苯二甲酸丁二酯、聚D-乳酸、聚L-乳酸、聚D，L-乳酸、或者聚酰胺-6等。聚烯烃为烯烃的聚合物，通常由乙烯、丙烯、1-丁烯、1-戊烯、1-己烯等α-烯烃单独聚合或共聚而得的一类热塑性树脂的总称。聚烯烃具有惰性的分子结构，分子链上不含活性基团，在本发明的应用领域中几乎不与液体成分反应，因此具有独特的优势。
当皮层21为聚乙烯时，芯层22可以为聚丙烯、聚对苯二甲酸乙二酯等聚合物。当皮层21为聚丙烯时，芯层22可以为聚对苯二甲酸乙二酯、聚酰胺等。双组分纤维2的皮层21熔点较低，有利于提高生产效率，降低制造成本。双组分纤维2的皮层21熔点较高，同时采用更高熔点的芯层22，制作的高温冷却段能耐受更高温度的气雾。
当皮层21为聚乳酸时，根据聚乳酸的熔点，如果采用熔点约130℃的聚乳酸为皮层21，芯层22可以为聚丙烯、聚对苯二甲酸乙二酯、熔点170℃左右的聚乳酸等。当皮层21为熔点150-185℃的聚乳酸时，芯层22可以为聚对苯二甲酸乙二酯、聚对苯二甲酸丁二酯、聚对苯二甲酸丙二酯、聚酰胺等。聚乳酸为生物降解材料，可以减少冷却元件300被抛弃时造成的环境污染。
制作本发明冷却元件300的双组分纤维2的纤度介于1-30旦，优选1.5-10旦，1.5-10旦的双组分纤维制造方便、成本较低，并且制成的冷却元件具有较大的毛细力，能更好地吸收并去除气雾中的冷凝液而形成干燥的气雾，有利于使用者感知到较低的温度。
在本实施例中，双组分纤维2为长丝或短纤，具有同心结构的皮层21和芯层22，皮层21为聚对苯二甲酸乙二醇酯的共聚酯，芯层22为聚对苯二甲酸乙二酯。
双组分纤维2的皮层21为熔点较高，能耐更高的气雾温度，如某些中药气雾散发装置，工作时加热元件的温度高达400℃或以上。若气雾散发装置工作时的温度较低，如雾化电子烟或加热不燃烧电子烟，可以用熔点较低的聚合物如聚丙烯、或聚L-乳酸等作为双组分纤维2的皮层21。
<冷却元件的工作原理>
根据本实施例的冷却元件300，用于冷却气雾散发装置中产生的气雾。气雾散发装置产生的气雾通过冷却元件300被适当地冷却。气雾通过热交换把自身的热量传导给冷却元件300而降低温度，冷却元件300吸收气雾中的热量后温度升高，冷却元件300中的物质在吸收热量后部分熔化，则可以吸收气雾中的大量热量，使气雾的温度显著降低。
本实施例中的冷却元件300由双组分纤维2粘结制成，双组分纤维2的皮层21和芯层22均为聚合物，聚合物发生某些相变时可以吸收热量，如聚合物熔化时晶区被破坏，从固态转 变为黏流态，这种相变过程需要从外界吸收大量的热量。
在应用了根据本实施例的冷却元件300的气雾散发装置中，气雾散发装置中产生的气雾，温度高于双组分纤维的皮层熔点。高温气雾从冷却元件300的一端流入并从其另一端逸出，冷却元件300的双组分纤维的皮层接触高温气雾时熔化，从而吸收气雾中的大量热量，使高温气雾的温度迅速降低。
在本实施例中，冷却元件300的双组分纤维2的芯层22的熔点比皮层21的熔点高25℃以上，双组分纤维2中的高熔点芯层22担当骨架，熔化的皮层21成为黏流态并附着于芯层22上，从而保持冷却元件300的完整性。
根据应用要求对冷却元件300进行设计，可以使气雾从冷却元件300的另一端逸出时的温度降至65℃以下，以适合抽吸者的口感。
<冷却元件的附加功能>
气雾从冷却元件300的一端流入并从其另一端逸出的过程中，温度逐渐下降，部分气化的气雾剂和水分冷凝成小液滴。由双组分纤维2粘结制成的冷却元件300具有大量的毛细孔，毛细孔能吸收气雾冷却时产生的冷凝液，使气雾变得干燥，有利于使用者感知到较低的温度。冷凝液可以吸收部分的酚类和醛类物质，因此冷却元件300的毛细孔吸收冷凝液的同时还能减少气雾中的酚类和醛类等有害物质。
可以在冷却元件中添加减少酚类物质的添加剂，比如甘油醋酸酯、柠檬酸三乙酯、低分子量乙二醇，以及甘油醋酸酯和醋酸纤维素纤维的混合物等。还可以在冷却元件中添加风味剂，如薄荷、天然或合成香精等，使使用者可以吸入具有不同风味的气雾。
第十二实施例
图12a是根据本发明第十二实施例的冷却元件的纵剖面图；图12b是根据本发明第十二实施例的冷却元件的横截面图。本实施例与第十一实施例结构相似，与第十一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，冷却元件300包括轴向贯穿冷却元件300的冷却元件通孔330。冷却元件通孔330的截面设置为星形，并且，如图2b所示，在冷却元件通孔330中插入内芯331。内芯331优选圆柱体结构，由于在星形的中空结构和圆柱体内芯331之间形成多个气流通道，使气雾通过冷却元件300时分成数股小气流，从而更充分地与冷却元件300接触并进行热交换。
第十三实施例
图13a是根据本发明第十三实施例的冷却元件的纵剖面图；图13b是根据本发明第十三实施例的冷却元件的高温冷却段的一种横截面图；图13c是根据本发明第十三实施例的冷却元件的高温冷却段的另一种横截面图；图13d是根据本发明第十三实施例的冷却元件的低温冷却段的横截面图。本实施例与第十一实施例结构相似，与第十一实施例相同的部分在本实施例的描述中不再赘述。
如图13a至13d所示，冷却元件300包括高温冷却段324和低温冷却段323。在应用了根据本实施例的冷却元件300的气雾散发装置中，气雾散发装置中产生的气雾，从冷却元件300的高温冷却段324的端部流入，并从低温冷却段323的端部逸出。
如图13b所示，冷却元件300的高温冷却段324具有轴向贯穿高温冷却段324的冷却元件通孔330。高温冷却段324优选设置为冷却元件通孔330截面为圆形的中空结构，其横截面形状为圆环。也可以如图13d所示，冷却元件300的高温冷却段324可以设置为冷却元件通孔330截面为星形的中空结构，其横截面形状为星形环，即中空结构的内孔的截面形状可以为五角星形、六角星形等。高温冷却段324采用中空结构，可以降低气雾穿过高温冷却段324的阻力，从而使高温气雾在气阻低的中空通道通过，中空通道内表面与高温气雾接触时，双组分纤维2的皮层21从高温气雾中吸收大量热量而熔化，使气雾温度迅速降低。当高温气雾主要从中空通道通过时，高温冷却段324的外周与高温气雾距离较远、温度传递至外周时已经降至较低温度，从而避免高温冷却段324的外周壁因高温而发生形变或损坏气雾散发装置的结构和性能。
在本实施例中，冷却元件300的高温冷却段324由双组分纤维热2粘结制成，高温冷却段324的孔隙率优选为80％，双组分纤维2为短纤，具有同心结构的皮层21和芯层22。
如图13c所示，本实施例中低温冷却段323采用非中空结构，低温冷却段323的横截面形状为实心圆面。低温冷却段323的孔隙率为90-95％，由偏心结构的双组分纤维2粘结制成。虽然低温冷却段323为非中空结构，但由于低温冷却段323的孔隙率高，仍具有较低的气阻。
气雾经过高温冷却段324冷却后，温度较低的气雾进入低温冷却段323。低温冷却段323与气雾进行热交换，低温冷却段323吸收热量温度升高，气雾将热量传导给低温冷却段323后温度进一步降低。若经过高温冷却段324冷却后的气雾温度高于低温冷却段323的双组分纤维2的皮层21的熔点，则低温冷却段323的双组分纤维2的皮层21会被部分熔化，使气雾温度迅速下降。根据应用要求对冷却元件300进行设计，可以使气雾从低温冷却段323的端面逸出时的温度降至65℃以下，以适合抽吸者的口感。采用非中空结构的低温冷却段323，气雾穿透低温冷却段323时，能与双组分纤维2进行更充分的热交换，能更好地降低气雾温 度。
在本实施例中，优选，高温冷却段324的皮层21的熔点大于低温冷却段323的皮层21的熔点。在高温冷却段324的双组分纤维2中，皮层21为熔点约170℃的聚L-乳酸，芯层22为熔点约265℃的聚对苯二甲酸乙二酯。在低温冷却段323的双组分纤维2中，皮层21为熔点约130℃的聚D，L-乳酸，芯层22为熔点约170℃的聚L-乳酸。
如果应用本实施例的冷却元件300的气雾散发装置载有尼古丁和甘油等成份，当气雾散发装置加热至375℃左右时，尼古丁和甘油等成份挥发并随着用户抽吸从产生气雾逸出，高温气雾进入冷却原件300的高温冷却段324。高温冷却段324的中空通道内壁与高温气雾接触并发生热交换，部分双组分纤维2的皮层21接触高温气雾时熔化，同时吸收气雾中的大量热量，使高温气雾的温度迅速降低，部分甘油冷凝成液体并被高温冷却段324吸收。高温冷却段324中双组分纤维2中的高熔点芯层22担当骨架，熔化的皮层21成为黏流态并附着于芯层22上，从而保持冷却元件300的完整性。
经过高温冷却段冷却后，温度较低的气雾进入冷却元件300的低温冷却段323。若进入低温冷却段323的气雾温度仍高于130℃，则低温冷却段323的双组分纤维2的皮层21会被部分熔化，使气雾温度迅速下降至130℃以下。随后低温冷却段323继续与气雾进行热交换，并利用低温冷却段323中聚乳酸在55℃至70℃之间的相变吸热，使气雾温度进一步降低至适合抽吸者的口感。
如图13d所示，本实施例中低温冷却段323采用非中空结构，气雾穿透低温冷却段323时与双组分纤维进行充分的接触和热交换，使气雾从低温冷却段323端部逸出时的温度降至65℃以下。气雾中的部分甘油和水分在低温冷却段323冷凝成液体后被低温冷却段323吸收，使气雾变得干燥，有利于使用者感知到较低的温度。
由于冷凝液可以溶解部分醛类和酚类物质，冷凝液被冷却元件300中的毛细孔吸收后可以减少用户对有害物质醛和酚的吸入。本实施例的冷却原件300的低温冷却段323中添加1-3％的甘油醋酸酯或甘油醋酸酯和醋酸纤维素纤维的混合物，用来减少气雾中的酚类物质含量。

第十九实施例
图19a为本发明所公开的第十九实施例的冷凝液吸收元件的纵剖面图；图19b为本发明所公开的第十九实施例的冷凝液吸收元件的横截面图。
如图19a和19b所示，根据本发明第十九实施例的冷凝液吸收元件400，用于气雾散发装置的气雾通道中吸收冷凝液，冷凝液吸收元件400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具有皮层21和芯层22。
皮层21优选为聚乳酸，或者是，优选为聚乙烯、聚丙烯、PBT或PTT等聚酯、或低熔 点共聚酯如聚对苯二甲酸乙二醇酯的共聚酯。
聚乳酸优选为聚D-乳酸，聚L-乳酸或聚D，L-乳酸。
<冷凝液吸收元件的密度及刚性>
本实施例的冷凝液吸收元件400密度为0.1克/厘米 3到0.4克/厘米 3，优选为0.2克/厘米 3到0.3克/厘米 3。当冷凝液吸收元件400的密度小于0.1克/厘米 3时，冷凝液吸收元件400的毛细力偏小，吸收冷凝液的能力较差，并且冷凝液吸收元件400轴向刚性过小，不利于在气雾散发装置中组装，尤其不利于高速自动化装配；当冷凝液吸收元件400的密度大于0.4克/厘米 3时，冷凝液吸收元件400径向刚性过高，在气雾散发装置中装配较为困难，并且单位体积冷凝液吸收元件400的吸液容量过小，空间利用效率差，不利于在空间狭小的气雾散发装置中使用。
本文中的刚性的比较方法是：将冷凝液吸收元件400沿轴向或者径向放置，夹持在两块平行的板之间，测量未压缩前的冷凝液吸收元件400的轴向高度或者径向高度；在施加同样作用力的情况下，测量两块板轴向或者径向压缩冷凝液吸收元件400后的轴向高度或者径向高度，并计算压缩的变形量，该压缩的变形量为未压缩前的轴向高度或者径向高度减去压缩后的轴向高度或者径向高度后的差值；将压缩的变形量除以未压缩前的冷凝液吸收元件400的轴向高度或者径向高度，获得压缩比。压缩比越小，则刚性越大，压缩比越大，则刚性越小。
冷凝液吸收元件400轴向的刚性大于其径向的刚性。在冷凝液吸收元件400的制作过程中，可以控制制作工艺，使冷凝液吸收元件400轴向的刚性大于其径向的刚性。由此便于组装时，冷凝液吸收元件400在轴向用力的作用下，径向能自适应地变形，并自适应地固定于气雾散发装置中，方便高速自动化组装。
<双组分纤维>
图19c是图19a和19b中的双组分纤维的一种截面放大示意图。如图19c所示，皮层21和芯层22为同心结构。同心结构的双组分纤维2刚性较大，生产方便。
图19d是图19a和19b中的双组分纤维的另一种截面放大示意图。如图19d所示，皮层21和芯层22为偏心结构。偏心结构的双组分纤维2较为柔软蓬松，容易制作密度较小的冷凝液吸收元件400。
双组分纤维2为长丝或者短纤。长丝制成的冷凝液吸收元件400强度较高，短纤制成的 冷凝液吸收元件400弹性较好。制造者可以根据冷凝液吸收元件400的性能要求选择合适的双组分纤维制成合适的密度和合适形状的冷凝液吸收元件400。
双组分纤维2的芯层22比皮层21的熔点高20℃以上。本实施例的冷凝液吸收元件400由皮芯结构双组分纤维2热粘结制成。双组分纤维2的芯层22比皮层21熔点高20℃以上，可以在纤维之间进行热粘结的时候使芯层22保持一定的刚性，便于冷凝液吸收元件400的制作。
双组分纤维2的皮层21为聚乳酸，简称PLA。聚乳酸由乳酸经化学反应制成，乳酸存在L和D光学异构体。聚乳酸包括聚L-乳酸、聚D-乳酸和聚D，L-乳酸。不同的聚乳酸有不同的熔点。由于原料纯度和生产工艺的差异，来自不同生产厂家的同一种类型的聚乳酸，可能有相同或不同的熔点；同一生产厂家的同一种类型但不同型号的聚乳酸可能有相同或不同的熔点。可以根据皮层21的聚乳酸的熔点来选择合适的芯层22材料。比如采用熔点125-135℃的聚D，L-乳酸为皮层21，可以用聚丙烯、聚对苯二甲酸乙二酯等为芯层22，也可以采用熔点165-180℃的聚D-乳酸或聚L-乳酸为芯层。再比如采用熔点155-170℃的聚D-乳酸或聚L-乳酸作为皮层21，可以选聚对苯二甲酸乙二酯、聚对苯二甲酸丁二酯、聚对苯二甲酸丙二酯、聚酰胺等为芯层22。聚乳酸为生物降解材料，可以被微生物完全分解成二氧化碳和水，尤其是当皮层21和芯层22均为聚乳酸时，冷凝液吸收元件可以全部被微生物分解，从而大大减少冷凝液吸收元件400使用后被抛弃所产生的环境污染。
双组分纤维2的皮层也可以为聚乙烯、聚丙烯、聚对苯二甲酸丙二酯、聚对苯二甲酸丁二酯或聚对苯二甲酸乙二醇酯的共聚酯、或者聚酰胺-6。可以根据皮层21的熔点来选择合适的芯层22材料。比如采用熔点125-135℃的高密度聚乙烯为皮层，可以用聚丙烯、聚对苯二甲酸乙二酯等为芯层22。再比如采用熔点160-170℃的聚丙烯为皮层21，可以选聚对苯二甲酸乙二酯、聚酰胺等为芯层22。再比如采用熔点110-120℃的低熔点共聚酯为皮层21，可以选聚对苯二甲酸乙二酯等为芯层22。再比如采用熔点225-235℃的聚对苯二甲酸丁二酯或聚对苯二甲酸丙二酯为皮层21为皮层21，可以选熔点255-265℃的聚对苯二甲酸乙二酯为芯层22。
双组分纤维2经粘结形成三维网络的立体结构。粘结可以采用多种方法，比如用胶水(最常见的粘结方法)、增塑剂(香烟过滤嘴的粘结方法)等。本发明优选通过热粘结形成三维网络的立体结构。通过热粘结的方法，成本低、并且不引入杂质。
<双组分纤维的纤度>
制作本发明冷凝液吸收元件400的双组分纤维2的纤度介于1旦到10旦，优选2旦到6 旦。低于1旦的皮芯结构双组分纤维2制造困难，成本高。高于10旦的纤维制成的冷凝液吸收元件400毛细力不足，吸收冷凝液的能力较差。
介于1旦到10旦的皮芯结构双组分纤维2容易热粘结成密度较低、并且具有合适毛细力的三维立体结构的冷凝液吸收元件400。纤度介于2旦到6旦的皮芯结构双组分纤维2尤为合适，并且成本较低。
<冷凝液吸收元件的形状>
本实施例的冷凝液吸收元件400可以根据气雾散发装置的内部结构需要制成合适的横截面外形，如圆形、椭圆形、长方形，或各种几何形状的组合，以方便在气雾散发装置中装配。可以根据需要在冷凝液吸收元件400的轴向设置冷凝液吸收元件通孔430，气雾从冷凝液吸收元件400周边通过或从冷凝液吸收元件通孔430中穿过时，气雾周围的冷凝液与冷凝液吸收元件接触从而被吸收。冷凝液吸收元件通孔430可以为圆形、椭圆形、长方形或各种几何形状的组合，冷凝液吸收元件通孔430可以为一个或多个。
在本实施例中，优选冷凝液吸收元件400由同心结构的双组分纤维2经热粘结形成三维网络的立体结构。双组分纤维2的纤度为2旦，皮层21为熔点125-135℃的聚D，L-乳酸，芯层22为熔点165-180℃的聚L-乳酸，制成的冷凝液吸收元件400密度介于0.2克/厘米 3到0.3克/厘米 3，这种冷凝液吸收元件400具有吸液容量大和吸收速度快的特性。如图1b所示，本实施例中冷凝液吸收元件400横截面外形为椭圆形，并设置横截面为圆形的轴向冷凝液吸收元件通孔430，当气雾穿过冷凝液吸收元件400的轴向冷凝液吸收元件通孔430时，气雾周围的冷凝液与轴向冷凝液吸收元件通孔430周壁接触并被吸收，防止冷凝液被使用者吸入口中，提升使用者的体验。
在本实施例中，也可以采用皮层21为熔点125-135℃的高密度聚乙烯，芯层22为熔点160-170℃的聚丙烯。

如果本实施例中的冷凝液吸收元件用于离雾化器较远的部位，皮层可以用熔点较低的聚乳酸替代，比如熔点145-160℃的聚L-乳酸或聚D-乳酸，熔点155-170℃的聚L-乳酸或聚D-乳酸，或熔点125-135℃的聚D，L-乳酸等。

第二十五实施例
图25a为本发明所公开的第二十五实施例的支撑元件的纵剖面图；图25b为本发明所公开的第二十五实施例的支撑元件的横截面图。
如图25a和25b所示，根据本发明第二十五实施例的支撑元件，用于气雾散发装置中支撑风味变换部件，支撑元件500由双组分纤维2经热粘结形成三维网络的立体结构，双组分纤维2具有皮层21和芯层22。
<支撑元件的形状>
支撑元件500可以具有轴向贯穿支撑元件500的支撑元件通孔530。支撑元件通孔530可以用于支撑风味变换部件(未图示)。例如，风味变换部件可以是爆珠，爆珠封装有诸如薄荷、天然或合成香精的风味剂。在装配时，爆珠插入支撑元件通孔530中，并由支撑元件通孔530支撑。用户使用时，可以挤压支撑原件500使爆珠破裂，使得风味剂逸出，并与气雾散发装置产生的气雾混合，改变气雾的风味，使用户能够体验不同风味的气雾。
通过支撑元件500来添加风味，因为风味被包覆于风味变换部件中，在储存过程中不发 生风味散失，也不存在雾化时因高温而发生分解的问题。
本实施例的支撑元件500可以根据气雾散发装置的内部空间制成合适的几何形状，如圆柱形、方柱形或者椭圆柱形等。可以不设置轴向支撑元件通孔530，在这种情况下，可以在支撑元件成型时将风味变换部件预埋于支撑元件中，或者在支撑元件中沿径向打孔，用于安装风味变化部件。
<支撑元件的密度>
本实施例的支撑元件500密度为0.08-0.35克/厘米 3，如0.08克/厘米 3、0.10克/厘米 3、0.12克/厘米 3、0.15克/厘米 3、0.18克/厘米 3、0.21克/厘米 3、0.25克/厘米 3、0.3克/厘米 3、0.35克/厘米 3，优选为0.1-0.25克/厘米 3。当密度小于0.08克/厘米 3时，支撑元件500制造困难，并且支撑元件500的强度不足，不易在气雾散发装置中组装；当密度大于0.35克/厘米 3时，支撑元件500的强度太大，使用时不易通过挤压支撑元件使风味变换元件破裂。
综合考虑制造、组装和使用的方便性，本发明确定支撑元件500优选的密度范围为0.1-0.25克/厘米 3，最优选为0.12-0.2克/厘米 3。
<双组分纤维>
如图25a和25b所示，根据本实施例的支撑元件500由双组分纤维2粘结形成三维网络的立体结构，双组分纤维2具有皮层21和芯层22。可以采用粘结剂、增塑剂或热量粘结纤维，优选用热量来粘结纤维以避免在制作支撑元件500的过程中引进杂质。本发明中所说的纤维组分是指制作纤维的聚合物。用于纤维表面的添加剂，如表面活性剂，并不被认为是纤维的组分。
图25c是图25a和25b中的双组分纤维的一种截面放大示意图。如图25c所示，皮层21和芯层22为同心结构。同心结构的双组分纤维2刚性较大，生产方便，价格较低。
图25d是图25a和25b中的双组分纤维的另一种截面放大示意图。如图25d所示，皮层21和芯层22为偏心结构。偏心结构的双组分纤维2较为柔软蓬松，容易制作密度较小的支撑元件500。此外，还可以采用并列结构的双组分纤维来制作支撑元件500，但热粘结时比较困难。当然，还可以采用三组分的皮芯结构纤维来制作支撑元件500，但三组分的皮芯结构纤维制造难度大，成本高，性价比较差。
双组分纤维2为长丝或者短纤。长丝制成的支撑元件500强度较高，短纤制成的支撑元件500弹性较好。制造者可以根据支撑元件500的性能要求选择合适的双组分纤维制成合适的密度和合适形状的支撑元件500。
双组分纤维2的芯层22比皮层21的熔点高25℃以上。本实施例的支撑元件500由皮芯结构双组分纤维2热粘结制成。双组分纤维2的芯层22比皮层21熔点高25℃以上，可以在纤维之间进行热粘结的时候使芯层22保持一定的刚性，便于制成密度较低的支撑元件500。
双组分纤维2的皮层21可以为聚乙烯、聚丙烯等聚烯烃、或对苯二甲酸乙二醇酯的共聚酯、聚酰胺-6和聚乳酸等常见的聚合物。聚烯烃为烯烃的聚合物，通常由乙烯、丙烯、1-丁烯、1-戊烯、1-己烯等α-烯烃单独聚合或共聚而得的一类热塑性树脂的总称。聚烯烃具有惰性的分子结构，分子链上不含活性基团，对风味剂吸附少，因此具有独特的优势。
当皮层21为聚乙烯时，比如线性低密度聚乙烯、低密度聚乙烯或高密度聚乙烯，芯层22可以为聚丙烯、聚对苯二甲酸乙二酯等聚合物。当皮层21为聚丙烯等其他聚烯烃时，芯层22可以为聚对苯二甲酸乙二酯、聚对苯二甲酸丙二酯或聚对苯二甲酸丁二酯、聚酰胺等。双组分纤维2的皮层21熔化温度低，有利于提高生产效率，降低制造过程中的能耗。
当皮层21为聚乳酸时，根据聚乳酸的熔点，如果采用熔点约130℃的聚乳酸为皮层21，芯层22可以为聚丙烯、聚对苯二甲酸乙二酯、熔点约170℃左右的聚乳酸等。当皮层21为熔点约170℃的聚乳酸时，芯层22可以为聚对苯二甲酸乙二酯、聚对苯二甲酸丁二酯、聚对苯二甲酸丙二酯、聚酰胺等。聚乳酸为生物降解材料，可以减少支撑元件500被抛弃时造成的环境污染。
<双组分纤维的纤度>
制作本发明支撑元件500的双组分纤维2的纤度介于1-30旦，优选1-15旦，最优选1.5-10旦。低于1旦的皮芯结构双组分纤维2制造困难，成本高。高于30旦的纤维难以制作支撑元件500。介于1-15旦的皮芯结构双组分纤维2容易热粘结成密度较低、并且具有合适毛细力的三维立体结构的支撑元件500，1.5-10旦皮芯结构双组分纤维2尤为合适，并且成本较低。
本实施例中，优选双组分纤维2的纤度为1.5旦、2旦、3旦或6旦，皮层21为熔点约130℃的聚乙烯，芯层22为熔点约165℃的聚丙烯，支撑元件500密度介于0.1-0.25克/厘米 3。
虽然支撑元件500也可以由单组份纤维，如聚丙烯纤维，用粘结剂粘结制成，但粘结剂的使用通常会使支撑元件500难以符合食品或药品的相关法规，这种支撑元件500不宜用于电子烟、药物雾化等气雾散发装置中。
如图25a、25b、25c和25d所示，在本实施例中，优选支撑元件500由同心结构的双组分纤维2经热粘结形成三维网络的立体结构。双组分纤维2的纤度为3旦，皮层21为熔点约130℃的聚乙烯，芯层22为熔点约270℃左右的聚对苯二甲酸乙二酯，制成的支撑元件500密度介于0.1-0.25克/厘米 3。支撑元件500形状为圆柱体，外径为7.5mm，并设置直径为3.5mm 的轴向支撑元件通孔530。这种支撑元件500的形状和尺寸适合于仿真烟形状的电子烟中使用。可以改变支撑元件500横截面的外径和轴向支撑元件的通孔530大小，制成不同尺寸的支撑元件500，方便在不同的气雾散发装置中使用。本实施例中双组分纤维2的皮层21可以用熔点约130℃的聚乳酸代替，制成的支撑元件500具有类似的性能。
气雾散发装置900雾化产生的气雾流经支撑元件500时，气雾在冷却过程中产生的冷凝液能够部分被支撑元件500吸收，减少气雾中的冷凝液，提升消费体验。
第二十六实施例
图26a为本发明所公开的第二十六实施例的支撑元件的纵剖面图；图26b为本发明所公开的第二十六实施例的支撑元件的横截面图。本实施例与第二十五实施例结构相似，与第二十五实施例相同的部分在本实施例的描述中不再赘述。
如图26a和26b所示，本实施例中，支撑元件500由同心结构的双组分长丝经热粘结形成三维网络的立体结构，双组分纤维2的纤度为6旦，皮层21为熔点约165℃的聚丙烯，芯层22为熔点230℃左右的聚对苯二甲酸丁二酯，这种支撑元件500具有较高的耐温性能，制成的支撑元件500密度介于0.25-0.35克/厘米 3，具有较大的刚性，适合于高速自动化组装。支撑元件500横截面图显示的形状为长方体，设置直径3mm的轴向通孔为支撑元件通孔530，这种支撑元件500的形状适合在长方体形状的扁烟中使用。本实施例中双组分纤维2的皮层21可以用熔点约170℃的聚乳酸代替，制成的支撑元件500具有类似的性能。
第二十七实施例
图27a为本发明所公开的第二十七实施例的支撑元件500的纵剖面图；图27b为本发明所公开的第二十七实施例的支撑元件500的横截面图。本实施例与第二十五实施例结构相似，与第二十五实施例相同的部分在本实施例的描述中不再赘述。
如图27a和27b所示，本实施例中，支撑元件500由偏心结构的双组分纤维2经热粘结形成三维网络的立体结构，双组分纤维2为短纤，其纤度为2旦，皮层21为熔点130℃的聚乳酸，芯层22为熔点155-185℃的聚乳酸，制成的支撑元件500密度介于0.12-0.2克/厘米 3。支撑元件500横截面图显示的为椭圆形，设置直径为2.5mm的轴向支撑元件通孔530，这种支撑元件500的形状适合在椭圆柱形状的扁烟中使用。本实施例中的支撑元件500完全由聚乳酸制成，能完全生物降解，对减少环境污染具有重要意义。
综上，本发明涉及的用于气雾散发装置的支撑元件500采用了皮芯结构的双组分纤维制 成,支撑元件500根据应用需求能在热粘结过程中制成需要的三维结构的尺寸和形状，从而适合高速的自动化组装，以降低气雾散发装置的制造成本。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，比如可以将两种不同纤度的双组分纤维混合来制备支撑元件500，或者在不影响支撑元件500整体性能的情况下将一些单组份纤维参杂于双组分纤维中以降低成本。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。
