具体实施方式
为了便于理解本申请，下面结合附图和具体实施方式，对本申请进行更详细的说明。
请参照图1和图2，本申请的一实施例提供一种雾化器，包括导油件、发热件、引线和安装座。
导油件至少一端与液体基质接触，用于吸取液体基质，然后将吸取的液体基质传导至导油件的受热部，所述的液体基质为在受热的情况下能够挥发，以产生出可供吸食的气溶胶的基液。
在一些实施例中，如图1、2、3和5所示，导油件1包括第一导油件11和第二导油件12，第二导油件12用于固定在安装座4中，以与发热件2接触，第一导油件11其一端用于面向用于储存液体基质的油仓51，并与液体基质接触，另一端用于面向安装座4，且与第二导油件12接触，以将液体基质传导至第二导油件12。
在一些实施例中，第一导油件11为片状或者块状的多孔纤维，其主要成分为高分子棉，可以是包含聚酯纤维的硬质人造棉，或者是包含丝状聚氨酯的硬质人造棉或人造泡棉等，第一导油件11通常具有介于柔性植物棉/无纺布与刚性多孔陶瓷/微孔金属之间的硬度或柔性，例如在一些示例中，第一导油件11具有介于20A至80A之间的邵氏硬度，因而结构稳定，在其吸收和浸润液体基质后具有极低的膨胀率，则装配后第一导油件11与外壳54的内壁之间的接触是介于柔性接触和刚性接触之间的接触，一方面第一导油件11利用自身的柔性可以独立地对油仓51进行密封，另一方面其又具有一定的硬度可以容易地被外壳54固定和保持。具体根据以上图中所示，第一导油件11的形状与油仓51下端的敞口基本是适配的，进而可以用于覆盖、封堵和密封油仓51。在另一些示例中，第一导油件11具有50～70A的邵氏硬度，大约等同于热塑性弹性体或硅胶相当水平的硬度。
可以参照图6、7，第一导油件11大致是椭圆形或者类椭圆形的形状，从而具有椭圆形或者类椭圆形的截面，油仓51下端的敞口也是椭圆形的形状。第一导油件11是由基本沿长度方向取向排列的例如聚乙烯和/或聚丙烯的取向纤维制备的，即第一导油件11中众多纤维束大致上是沿同一方向排列延伸的，例如基本垂直于第一导油件11的厚度方向延伸。可以理解的是，相同取向的纤维材料一方面能够提高导油片11 自身的抗弯折强度，另一方面从液体的传输方向上来考量，液体从导油片11沿厚度方向的一侧渗透传递到另一侧，相同取向的纤维材料能够将液体传输速率控制至合理范围，从而防止液体传输速率过快。
通过取向纤维在第一导油件11的长度方向上排布，使在第一导油件11呈现较强的抗弯折强度进而呈硬质的特点。并且采用以上有机纤维制备的第一导油件11，在制备的过程中使纤维材料之间保留充足的空隙，进而既能传递液体基质，还能使第一导油件11具有适当的柔韧性。在一些示例中，具有以上取向纤维的第一导油件11是呈各向异性的。具体一方面具有至少沿长度方向的抗折强度大于沿宽度方向的抗折强度；或者另一方面，具有沿长度方向的导液速率大于沿宽度方向的导液速率。
本一实施例中，第一导油件11在长轴方向(长度方向)的长度L介于14.4mm至18.4mm之间，在短轴方向(宽度方向)的宽度W可以介于7.2mm至8.0mm之间，第一导油件11的厚度可以介于1.5mm至2.5mm之间。在另一实施例中，第一导油件11在长轴方向(长度方向)的长度L可以为16.4mm，在短轴方向(宽度方向)的宽度W可以为7.6±0.01mm，第一导油件11的厚度可以为2±0.1mm。在又一实施例中，第一导油件11中的有机纤维具有大致上沿该第一导油件11长度方向的取向。在又一实施例中，第一导油件11包括纤维材料，纤维材料的纤维束大致上沿与第一导油件11的第一表面和第一导油件11的第二表面之间的液体传递方向相垂直的方向取向延伸，第一导油件11的第一表面面向油仓51，第一导油件11的第二表面面向第二导油件12且与第二导油件12接触。
在一些实施例中，第一导油件11的表面或内部具有沿长度方向延伸的纹路；具体的，纹路是由以上取向纤维通过辊筒压制等的纺织工艺制备的，并且在制备的过程中通过辊筒压制或水刺工艺等使部分纤维之间的间距加大，从而在间距加大的位置形成肉眼可见的凹痕，宽度小于1mm，大约介于0.1～0.5mm；进而由以上凹痕在第一导油件表面或内部形成纹路，对于液体基质的传递和保持、以及提升硬质性能是有利的。配合第一导油件的上述特征，第一导油件11中纤维材料的密度大于第二导油件12中纤维材料的密度。例如在一些示例中，第一导油件11在未吸收液体基质状态下的密度介于0.26mg/mm3至0.31mg/mm3之间，如可以为0.2850.15mg/mm3，以确保第一导油件11吸附和传递液体基质的速度满足消耗液体基质产生适量气溶胶的需求，从而使导油件1可配合发热件6-8W的发热功率，保证供油平衡，避免出现炸油。
第二导油件12为用于承载发热件2的载体，主要用于将从第一导油件11上吸附的液体基质，传递至发热件2所在处，以供发热件2加热使液体基质挥发。
第二导油件12可以是柔性的，如可以是由柔性的条带或杆状的纤维材料制备的，例如棉纤维、无纺布纤维、海绵体等，具有小于第一导油件11的硬度。在其它示例中，第二导油件12也可以与第一导油件11采用相同的材料制成，具有介于通常柔性植物棉/无纺布(邵氏硬度小于20A)与刚性多孔陶瓷/微孔金属(邵氏硬度大于80A)之间的硬度或柔性，则装配后第二导油件12与安装座4的内壁之间的接触是介于柔性接触和刚性接触之间的接触，从而因具有一定的硬度可以容易地被安装座4固定和保持。
在一些实施例中，如图2、3、5和6所示，第二导油件12为U型结构，包括连接部123和设置在连接部123相对两端的臂部122，所述的受热部121位于该U型结构的连接部123上，U型结构的两臂部122可以凸伸出安装座4，用于与第一导油件11接触，以将液体基质传导至U型结构的连接部123，同时U型结构的两臂部122朝向安装座4的至少局部部位可与安装座4之间具有力的作用，从而使导油件1至少局部固定在安装座4中。
在一些实施例中，连接部123的延伸长度介于8mm至10mm之间，臂部122的延伸长度介于6.5mm至8.5mm之间，第二导油件12在未吸收液体基质状态下的重量介于1g至1.4g之间，从而确保第二导油件12上具有足够的液体基质，以产生高口感、高品质的气溶胶量。在另一些实施例中，连接部123的延伸长度可以为9mm，臂部122的延伸长度可以为7.5mm，第二导油件12在未吸收液体基质状态下的重量可以为1.2g，从而确保第二导油件12上具有足够的液体基质，以产生高口感、高品质的气溶胶量。
发热件2至少附着于受热部121，受热部121的内径相对于连接部123的其他处的内径小。发热件2在通电时发热，以加热受热部121上的发热件2热辐射范围内的液体基质使之挥发。
在一些实施例中，如图3、5和6所示，发热件2通过缠绕在受热部121上而附着于导油件1。
在一些实施例中，发热件通过埋设于所述受热部中而附着于所述导油件。
在一些实施例中，如图2所示，发热件2包括至少两根并行的电热丝，两电热丝或多电热丝采用双丝缠绕或多丝缠绕的方式附着于导油件 1上。电热丝可以都是镍丝。在一可选方案中，发热件2包括并行的双电热丝时，每一电热丝的丝径小于0.16mm(常规的电热丝的丝径为0.16-0.25mm)，相较常规电热丝的丝径，本实施例所述的电热丝的丝径更小，从而本实施中的每一电热丝的外表面都能和导油件上的液体基质充分接触(丝径较大的电热丝的局部外表面可能由于远离导油件，而不能被导油件上的液体基质浸没，从而不能与液体基质充分接触)，从而能够使受热部121上的液体基质受热均匀，不会出现因为局部温度过高而炸油。在该具体实施例的进一步的方案中，每一电热丝的丝径为0.12mm。
在一些实施例中，引线3是由相对电热丝粗的导线制成，引线的直径大约为0.13～0.3mm，本实施例中，引线的直径可以约为0.25mm。
在一些实施例中，在电热丝的丝径小于常规丝径的前提下，所述的并行电热丝相互并联。发热件缠绕受热部的螺旋圈具有大约3～10个匝或绕组，螺旋圈的轴向长度大约为4～7mm，在本实施例的某一具体方案中，可以参照图2，发热件2缠绕受热部的螺旋圈具有5个匝数或绕组，相邻匝间距约为1mm，第一引线31和第二引线32与发热件2两端连接的连接点之间的距离约为6.4mm(即螺旋圈的轴线长度大约为6.4mm),从而在6-8W的发热功率下，发热件2发热配合上述的第二导油件12的属性能够使液体基质雾化产生适量的气溶胶，提高口感。
在一些实施例中，发热件2的螺旋圈的内径大约为1.5～4mm的内径，发热件2的阻值大约0.5～2欧姆，在一些优选示例中，发热件2的螺旋圈的内径为2.13±0.05mm，阻值为1.2±0.1Ω。
请参照图6，发热件2的两端分别连接有一引线3，发热件2通过第一引线31电连接正电极61，通过第二引线32电连接负电极62。安装座4上具有两穿孔41，用于供所述第一引线31和所述第二引线32穿过，两穿孔41可以位于安装座4的底部，穿孔41的延伸方向与第二导油件12安装入安装座4的行进方向一致，从而可以在引线3穿过穿孔41的过程中，第二导油件12可以靠近甚至进入安装座4中。在一些示例中，安装座4采用硅胶等柔性材料制作，上述穿孔41是非完全贯通的并且在该穿孔41内具有能够被穿刺或破坏的薄弱区域，在装配过程中第一引线31和第二引线32可以分别穿刺对应穿孔41内薄弱区域，从而通过穿孔41。第一引线31和第二引线32的外表面与薄弱区域保持密封，可阻止液体基质通过该穿孔41。
在一些实施例中，如图6所示，第一引线31和第二引线32在初始状态时，第一引线31的长度比第二引线32长。在一些实施例中，两穿 孔41的引线穿入端可以具有大致相同的高度，其中，穿孔41的近端为引线穿入端，远端为引线穿出端。
在一些实施例中，如图3、5和6所示，在组装所述的雾化器时，由于第一引线31比第二引线32长，且两穿孔41的引线穿入端具有大致相同的高度，首先使第一引线31穿过与之对应的穿孔41，然后使第一引线31沿着其穿入的行进方向继续行进，然后使第二引线32靠近并穿过与之对应的穿孔41，然后使第一引线31和第二引线32继续沿着其穿入的行进方向行进，直至第二导油件12的至少局部区域被固定在所述安装座4中。在这个过程中，由于第一引线31比第二引线32长，从而第一引线31会比第二引线32先穿入对应的穿孔41中，无需使第一引线31和第二引线32同时对准相应穿孔41，降低穿插的难度。且由于第一引线31比第二引线长32，在第二引线32即将插入穿孔41时，若所述第一引线31和所述第二引线32的长度差大于或者等于穿孔41的孔深，则第一引线31已经或者即将穿出对应的穿孔41，从而第一引线31不会因为抖动等意外从穿孔41中退出，所以能够防止反复使同一引线3穿入与其对应的穿孔41中。同时由于第一引线31比第二引线32长，从而在使第一引线31插入穿孔41时，第二引线32距离与之对应的穿孔41还有一定的距离，在使第二引线32插入穿孔41时，第一引线31已经或即将穿出相应的穿孔41，从而可以避免在穿插其一引线3时，使另一引线3被安装座4抵顶至弯曲。
可以是第一引线31与正电极电连接，第二引线32与负电极电连接，亦可以是第一引线31与负电极电连接，第二引线32与正电极电连接。
在一些实施例中，由于正电极61和负电极62与发热件2之间的距离大致相等，所以为了方便与正电极61、负电极62连接，至少第一引线31和所述第二引线32中的第一引线31上具有冗余段(未图示)，冗余段可被去除，去除冗余段的方式包括将其剪掉，或将其折弯，或将其折断等。在第二导油件12的至少局部区域与安装座4相互固定之后，或者在第一引线31和第二引线32均穿过相应的穿孔41之后，去除该冗余段，冗余段被去除后的所述第一引线31和所述第二引线32的长度差小于冗余段被去前的所述第一引线31和所述第二引线32的长度差，如：冗余段被去除后的第一引线31和第二引线32的长度差可以为0，或者近乎为0，或者介于0.1mm至2mm之间。
为了避免浪费，防止冗余段过长，在某些实施例中，所述第一引线31和所述第二引线32的长度差大于或者等于安装座4的高度，安装座4的高度为安装座4轴向至高点与至低点之间的最短垂直距离，使得在 第一引线31即将穿出相应的穿孔41时，第二引线32至少即将伸入安装座4中。在某些具体的应用方案中，第一引线31和第二引线32的长度差介于3mm至15mm之间，穿孔41的孔深不大于3mm，安装座4的高度不小于15mm。
如图1、3、5和6所示，安装座4上还设有两电极孔42，分别用于收容正电极61和负电极62的至少局部区域，将电极孔42设于安装座4上，有助于缩短所需引线3的长度。
如图1所示，第一引线31和第二引线32穿出穿孔41后可以被弯折，从而形成弯折部，弯折部的自由端进入对应的电极孔41中，以与正电极61或负电极62电连接。若引线3无冗余段，则直接弯折第一引线31和第二引线32，使之自由端进入电极孔42中，若引线3有冗余段，则在去除冗余段后，再弯折引线3使之自由端进入电极孔42中。受电极孔42的孔深和电极孔42与穿孔41穿出端之间距离的限制，若引线3的自由端过长，则不利于其插入电极孔42中，所以需要对其进行剪短，将自由端上的冗余段去除。
本申请某一实施例中，正电极61、负电极62可与对应的电极孔42过盈配合，从而，将引线3的自由端弯折后插入电极孔42后，再将正电极61、负电极62的至少局部区域插入电极孔42中，即可实现正电极61、负电极62与相应引线3之间地电连接。
如图3和5所示，电极孔42为盲孔，以避免引线3的自由端穿出电极孔42而再次进入安装座4中第二导油件12的固定空间，防止引线3的自由端再次与发热件2电连接。
在一些实施例中，电极孔42位于安装座4的底部，且电极孔42与穿孔41平行，以方便正电极61、负电极62安装和缩第二引线3的长度。
在一些实施例中，如图1所示，安装座4的底部具有进气孔45，进气孔45正对受热部121，两穿孔41位于进气孔45的相对两侧。
本申请的一实施例亦提供一种雾化器，该雾化器与上述的雾化器之间的区别主要在于：两穿孔的近端被配置成不同的高度以使所述第一引线和所述第二引线先后穿入其中，其中，穿孔的近端为引线穿入端，远端为引线穿出端。在本实施例中，所述第一引线和所述第二引线可以具有相同的长度，或者第一引线对应近端高度较高的穿孔，第二引线对应近端高度较低的穿孔。
在组装该雾化器时，由于两穿孔近端的高度不同，首先使一引线穿过近端高度较高的穿孔，然后使该引线沿着其穿入的行进方向继续行进，使另一引线靠近并穿过剩余的近端高度较低的穿孔，然后使所述第一引 线和所述第二引线继续沿着其穿入的行进方向行进，直至第二导油件的至少局部区域被固定在所述安装座中。在这个过程中，由于两穿孔近端的高度不同，从而近端高度较高的穿孔先被引线穿入，近端高度较低的穿孔后被引线穿入，无需使所述第一引线和所述第二引线同时对准相应穿孔，从而降低穿插的难度。
如图4-6所示，本申请的一实施例提供一种电子雾化装置，包括雾化器、油仓、气道、正电极和负电极。
这里所述的雾化器可以为本申请上文所述的雾化器。
油仓51用于存储液体基质，雾化器中的第一导油件11位于油仓51与安装座4之间，一方面密封油仓51，防止油仓51中的液体基质泄漏，另一方面隔绝油仓51与安装座4，确保安装座4中的发热件2能够正常工作，第一导油件11与液体基质接触，然后将液体基质吸附并传导至油仓51之外的第二导油件12上的发热件2上，发热件2在通电时会产生使其上的液体基质雾化的热量。
气道52的近端设有吸嘴521，吸嘴521用于与嘴部接触，气道52的远端连接雾化器，雾化器加热液体基质使之雾化生成的气溶胶进入气道52，并随着吸嘴521处的抽吸，沿着气道52来到吸嘴521处，最后进入嘴部。
正电极61和负电极62用于电连接电源(未图示)和引线3，电源输出的电流、电压或者电功率通过正电极61和负电极62、引线3传至发热件2，以使发热件2发热。
在一些实施例中，如图5和图6所示，雾化器还包括外壳54，外壳54的远端具有敞口，气道52位于外壳54内部且可以和外壳5一体成型，油仓51位于气道52外侧壁与外壳54内壁之间的至少局部空间，雾化器固定在外壳54的远端敞口处。
在一些实施例中，如图5和图6所示，第一导油件11近端表面、气道52外壁和外壳54内壁之间的空间为油仓51，第一导油件11上具有通孔111，气道52的远端穿过该通孔111伸入安装座4中，气道52与通孔111之间的接触为密封接触，气道52与通孔111接触后，可防止油仓51中的液体基质渗进气道52与通孔111接缝而泄漏。第一导油件11具有介于柔性植物棉/无纺布与刚性多孔陶瓷/微孔金属的硬度或柔性，气道52穿过该通孔111后，通孔111内部与气道52外壁之间的接触是介于柔性接触和刚性接触之间的接触，一方面第一导油件11利用自身的柔性可以独立地对气道52与通孔111的接缝进行密封，另一方面通孔111又具有一定的硬度可以容易地固定和保持气道52。
安装座4中具有止挡部43，止挡部43被气道52的远端开口止挡，从而雾化器自外壳54的远端敞口向外壳54近端所在方向，沿外壳54的内壁进入外壳54内部一定深度时，止挡部43会被气道52的远端止挡，以防止其继续进入而使气道52的远端抵顶到第二导油件12。安装座4与外壳54内壁过盈配合，并且安装座4外侧壁上设有密封圈44，以防止漏气和漏油，在一些示例中，密封圈44是安装座4的一部分。
在一些实施例中，雾化器还包括供空气进入至油仓内的气压平衡通道，以向油仓内补充空气进而缓解油仓由液体基质的消耗引起的负压。具体在实施中，可以参照图5、6，外壳54的内侧上至少有一处与第一导油件11的侧壁之间具有间隙541，以作为所述的气压平衡通道。可选的，对应每一间隙541，外壳54上具有至少两条并行的凸肋，外壳54通过凸肋抵接第一导油件11，从而使间隙541形成在凸肋、外壳54和第一导油件11之间。可选的，第一导油件11的侧壁包括第一部112和第二部，第二部为弧形部，外壳54的内壁为弧形，第一导油件11的弧形部与外壳54的弧形内壁相贴或者过盈配合，第一导油件11的第一部112与外壳54的弧形内壁之间具有间隙541，以作为气压平衡通道。进一步的，对应每一间隙541，外壳54上具有至少两条并行的凸肋，第一导油件11的侧壁包括第一部112和与外壳54的内壁相贴的贴合部，凸肋抵接第一部112，从而使间隙541形成在凸肋、外壳54和第一部112之间。可以参照图6、7，第一导油件11上的第一部112可以有两个，对称设置，且与长轴方向垂直。可以参照图4，正电极61和负电极62固定在基座53上，且正电极61和负电极62的局部穿过基座53伸入电极孔42中，从而与已经伸入电极孔42中的引线3电连接。该基座53通过卡扣或者螺纹等方式与外壳54远端的敞口可拆卸地连接。正电极61和负电极62的局部显露在基座53之外，以与电源组件电连接。基座53与安装座4抵接，以防止安装座4从外壳54中退出。
本申请的亦提供一种电子雾化装置的实施例，包括电源组件和上述的雾化器，电源组件与雾化器可拆卸地连接，从而在电子雾化装置中的电源组件电量耗尽或者损坏后，可以更换电源组件。或者，在所述雾化器中液体基质耗尽或者损坏后，可以更换与电源组件连接的雾化器。
所述电源组件包括电源和与电源电连接的正输出电极、负输出电极，所述正输出电极和负输出电极分别与所述正电极和负电极电连接。电源组件用于通过正输出电极和负输出电极向雾化器提供液体基质雾化所需的电能。
需要说明的是，本申请的说明书及其附图中给出了本申请的较佳的 实施例，但并不限于本说明书所描述的实施例，进一步的，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本申请所附权利要求的保护范围。
