Description

电子烟及其雾化组件的制造方法
【技术领域】
本发明涉及一种电子烟及其雾化组件的制造方法。
【背景技术】
电子烟又名虚拟香烟、电子雾化器。电子烟作为替代香烟用品，多用于戒烟。电子烟具有与香烟相似的外观和味道，但一般不含香烟中的焦油、悬浮微粒等其他有害成分。
电子烟主要由雾化器和电源组件构成。雾化器作为电子烟产生雾化气体的核心装置，其雾化效果决定了烟雾的质量与口感。一般的雾化器的加热体为弹簧状的发热丝，其制作过程为将线状的发热丝缠绕在一根导液绳上。烟液存储器中的烟液通过导液绳两端吸附到导液绳上，然后被发热丝加热雾化。然而，这种类型电子烟的烟液完全靠导液绳的两端来吸取，然后雾化，由于导液绳端部的面积有限，导致烟液吸附效率较低，因而，当使用大功率的发热丝时，就会出现导液绳供液不足，出现干烧，产生焦味。
为解决上述供液不足的问题，现有技术中的改进方案是将螺旋状发热丝外部包覆导液棉等导液结构，此时导液棉整个侧面都可以用来导液，因此供液量充足。然而，该种改进方案中，存在以下问题：1.经常出现烟油爆裂的声音；2.雾化效率低，即同样功率的情况下，烟雾量相对较小。
【发明内容】
基于此，有必要提供一种雾化效果更好的电子烟。
一种电子烟，包括：
储液器，用于存储烟液；
雾化组件，收容在所述壳体内，所述雾化组件包括：
吸液元件，与所述储液器相连，所述吸液元件的材料为多孔陶瓷，所述吸液元件具有用于吸收烟液的吸液面，及雾化表面；及
发热元件，所述发热元件嵌入所述吸液元件的内部，所述发热元件的边缘与所述雾化表面内切，所述发热元件用于将所述吸液元件所吸附的烟液转化为烟雾；及
电源组件，收容在所述壳体内并与所述雾化组件相连，用于给所述发热元件提供电源。
一种雾化组件的制造方法，包括：
提供定位件，所述定位件包括固定柱；
将发热元件呈螺旋状缠绕在所述固定柱的周围；
将缠绕有所述发热元件的固定柱放入模具中，在所述发热元件的表面注塑第一层陶瓷材料，然后固化；
从固化的第一层陶瓷材料中取出所述固定柱，及
烧结固化的第一层陶瓷材料，从而得到由多孔陶瓷构成的吸液元件和嵌入在所述吸液元件内部的发热元件。
一种电子烟，包括：
储液器，收容在所述壳体内，用于存储烟液；
雾化组件，收容在所述壳体内，所述雾化组件包括：
支撑件，所述支撑体的内部形成雾化通道，所述支撑件的侧壁上开设有与所述雾化通道相通的相对的两个贯通孔，
吸液元件，所述吸液元件的材料为多孔陶瓷，所述吸液元件的两端穿设于所述贯通孔并伸入所述储液器内，所述吸液元件具有用于吸收烟液的吸液面及位于所述雾化通道内的雾化表面；
发热元件，嵌入所述吸液元件的内部，且所述发热元件的边缘与所述雾化表面内切；及
电源组件，收容在所述壳体内并与所述雾化组件相连，用于给所述发热元件提供电源。
相对于现有技术，由于发热元件完全嵌入在吸液元件内部，而由多孔陶瓷构成的吸液元件内部充满了烟液，因此，整个发热元件完全与烟液接触，雾化效果较好。

请同时参阅图1和图2，实施例一的电子烟100包括壳体120、烟嘴盖140、储液器150、雾化组件160及电源组件180。
壳体120大致为长条形的空心圆筒。烟嘴盖140设置在壳体120的一端，雾化组件160及电源组件180收容于壳体120的内部。可以理解，壳体120也可以为方形或是其他形状。
烟嘴盖140的外侧设有螺纹，并通过该螺纹螺合固定于壳体120的顶端。烟嘴盖140的中部还开设有一个出气孔142。可以理解，烟嘴盖140也可省略。
储液器150大致为空心的圆形管状体，其主要用于存储烟液。储液器150的内部沿轴向开设有大致呈圆柱形的烟道151。烟道151与出气孔142相对应。储液器150内还设有用于吸收烟液的储液介质153。储液介质153可以采用纤维等材质制成，优选地，采用改性的纤维制成。通过改性处理可以去除烟液的异味，以免影响烟雾的口味。
雾化组件160包括吸液元件164及发热元件166。
吸液元件164与储液器150相连。本实施例中，吸液元件164的形状大致为与烟道151相配合的圆管。因此，吸液元件164可以插入到储液器150的烟道151的内部，从而与储液介质153直接接触。吸液元件164可采用具有储液、耐温性能的多孔陶瓷材料制成。由此，来自储液介质153的烟液通过毛细管作用能够均匀地分散到吸液元件164的内部和表面。构成吸液元件164的多孔陶瓷的孔隙率为30%~60%，优选为35%~45%。孔隙率太高会导致漏液的风险提高；孔隙率太低则会出现供液不足等问题。吸液元件164的内部沿轴向开设有与烟道151相通的雾化通道165。吸液元件164具有与储液介质153接触的用于吸收烟液的吸液面1642，本实施例中，吸液面1642为吸液元件164的外圆周面。吸液元件164还具有位于雾化通道165的侧壁的雾化表面1652。
发热元件166嵌入吸液元件164的内部。本实施例中，发热元件166为形状为螺旋管状的发热丝，且发热元件166的边缘与雾化表面1652内切（平齐）。发热元件166采用具有弹性的金属或合金等导电材质制成，优选为镍铬合金丝。当发热元件166通电时，发热元件166能够加热吸液元件164，从而使得存储在吸液元件164内部的烟液能够均匀受热而转化为均匀的雾化颗粒（即烟雾）。该烟雾可以从雾化表面1652进入雾化通道165，再进入到烟道151，并最后通过出气孔142进入使用者的口中。
现有的电子烟中，由于螺旋状发热丝内表面不与烟液直接接触，因此其上仅有一点通过毛细作用或表面张力等方式爬到其上的烟液，存在问题如下：a.一旦通电，内侧温度会瞬间升至高温，与烟液接触即会产生爆裂声(因为烟液温度低，发热丝内侧温度太高)；b.在雾化过程中，这点烟液太少，导致螺旋状发热丝内外侧的温度差较大，内侧温度过大，一旦烟油触碰该高热区域，会出现雾化温度过高而产生裂解，发生化学反应，甚至产生甲醛气体；c.使用者抽吸时，由于气流直接接触内侧发热丝，导致气流温度较高，同时内侧发热丝热量浪费，导致雾化效率较低。而在本实施例中，由于发热元件166完全嵌入在吸液元件164内部，而由多孔陶瓷构成的吸液元件164内部充满了烟液，因此，整个发热元件166完全与烟液接触。这可带来以下优点：a. 螺旋状发热丝内外表面温度分布均匀；b.热量浪费少；c.没有烟油爆裂声或爆裂声少；d.不会产生或产生较少甲醛等有害物质。
请一并参阅图3A，在一个实施例中，发热元件166呈螺旋状环绕在雾化通道165的周围，且发热元件166至雾化表面1652的距离d小于发热元件166至吸液元件164的吸液面1642的距离D。从而可以让由多孔陶瓷制成的吸液元件164的吸液面1642具有较低的温度，不会将过多的热量传导储液器150中的烟液，避免未被雾化的烟液温度升高，否则一是浪费能量，二是对使用者的握持带来不便。在另一个实施例中，吸液元件164的导热效率由内到外沿径向方向逐渐减小，这样也可达到降低表面温度的效果。
在一个实施例中，上述雾化组件的制造方法，包括如下步骤：
步骤一、提供定位件，所述定位件包括固定柱；
步骤二、将发热元件呈螺旋状缠绕在所述固定柱的周围；
步骤三、将缠绕有所述发热元件的固定柱放入模具中，在所述发热元件的表面注塑第一层陶瓷材料，然后固化；
步骤四、从固化的第一层陶瓷材料中取出所述固定柱，及
步骤五、烧结固化的第一层陶瓷材料，从而得到由多孔陶瓷构成的吸液元件和嵌入在所述吸液元件内部的发热元件。
采用上述方法将发热丝烧结固定在多孔陶瓷构成的吸液元件中，具有如下有益效果：发热丝可通过吸液元件得到支撑，因此，其本身直径可以较小，由于同样阻值的情况下，直径越小，长度越短，因此，整体体积会很小。这一方面是能节省材料，更重要的是能够小型化。这样包覆发热丝的吸液元件的体积即可做小，从而可以提高整个吸液元件的升温速度。
请参阅图3B，在另一个实施例中，吸液元件164包括靠近雾化通道165的第一层164a和远离雾化通道165的第二层164b。第一层164a和第二层164b的材料不同，第一层164a的导热效率高于第二层164b的导热效率。发热元件166嵌入吸液元件164的第一层164a。这种设计也可以让降低吸液元件164的吸液面的温度，节省能源且提高使用者的用户体验。
在一个实施例中，上述雾化组件的制造方法，包括如下步骤：
步骤一、提供定位件，所述定位件包括固定柱；
步骤二、将发热元件呈螺旋状缠绕在所述固定柱的周围；
步骤三、将缠绕有所述发热元件的固定柱放入模具中，在所述发热元件的表面注塑第一层陶瓷材料，然后固化；
步骤四、在所述第一层陶瓷材料的表面注塑第二层陶瓷材料，然后固化，所述第一层陶瓷材料的导热效率高于所述第二层陶瓷材料的导热效率；
步骤五、从固化的第一层陶瓷材料和第二层陶瓷材料中取出所述固定柱，及
步骤六、烧结固化的第一层陶瓷材料和第二层陶瓷材料，从而得到由多孔陶瓷构成的吸液元件和嵌入在所述吸液元件内部的发热元件。
请再次参阅图1，电源组件180包括电极座184和电池（图未示）。发热元件166的两端通过两根导线182与电源组件180的电极座184分别相连。电池用于给发热元件166提供电源。可以理解，电源组件180还可以包括咪头、指示灯等常规元件，在此不再赘述。
请同时参阅图4和图5，实施例二的电子烟200与实施例一的电子烟100较为相似，包括壳体220、烟嘴盖240、储液器250、雾化组件260及电源组件280，其区别在于：本实施例中，吸液元件264的形状大致为与壳体220相配合的圆管。吸液元件264收容于壳体220内，并位于储液器250的一端。吸液元件264具有面向储液器250用于吸收烟液的吸液面2642。来自储液器250的烟液可通过毛细作用能够经吸液面2642均匀地分散到吸液元件264的内部和表面。吸液元件264的内部开设有与烟道251相通的雾化通道265，发热元件266为嵌入吸液元件264的内部的形状为螺旋管状的发热丝。发热元件266呈螺旋状环绕在雾化通道265的周围，且发热元件266的边缘与雾化表面内切（平齐）。与实施例一相比，本实施例的吸液元件264位于储液器250一端，从而便于安装。
请同时参阅图6和图7，实施例三的电子烟300与实施例二的电子烟200较为相似，包括壳体320、烟嘴盖340、储液器350、雾化组件360及电源组件380，其区别在于：电子烟300还包括设于储液器362与吸液元件364之间的盖体37。盖体37大致为圆管形，其设置在储液器350的一端用于密封储液器350。盖体37的中部开设有与烟道351相通的排气道372。盖体37位于排气道372的周围还开设有均匀分布四个导液通道374。储液器350内没有设置储液介质，其内的烟液可以通过该四个导液通道374流入到吸液元件364内。吸液元件364的内部开设有与排气道372相通的雾化通道365，发热元件366为嵌入吸液元件364的内部的形状为螺旋管状的发热丝。与实施例二相比，本实施例的烟液通过导液通道374流入到吸液元件364中，因此可以较为精确地控制烟液的流量。可以理解，导液通道374的数量也可以为三个、五个或更多。
请同时参阅图8和图9，实施例四的电子烟400与实施例二的电子烟200较为相似，包括壳体420、烟嘴盖440、储液器450、雾化组件460及电源组件480，其区别在于：雾化表面4642为吸液元件464远离储液器450的端面。发热元件466为平面螺旋形（即具有阿基米德螺线）的发热丝。发热元件466嵌入吸液元件464的内部，并设于吸液元件464远离储液器462的一端。发热元件466呈螺旋状环绕在雾化通道465的周围，且发热元件466的边缘与雾化表面4642内切（平齐）。当发热元件466通电时，发热元件466能够从一端加热吸液元件464，从而使得存储在吸液元件464内部的烟液能够均匀受热而转化为均匀的雾化颗粒（即烟雾）。该烟雾可以从雾化表面4642进入雾化通道465，再进入到烟道451，并最后通过出气孔进入使用者的口中。
在一个实施例中，上述雾化组件的制造方法，包括如下步骤：
步骤一、提供定位件，所述定位件具有定位平面和设于所述定位平面上的固定柱；
步骤二、将发热元件呈平面螺旋状放置在定位平面上，并环绕在所述固定柱的周围；
步骤三、将放置有所述发热元件的定位件放入模具中，在所述发热元件的表面注塑第一层陶瓷材料，然后固化；
步骤四、从固化的陶瓷材料中取出所述定位件，及
步骤五、烧结固化的陶瓷材料，从而得到由多孔陶瓷构成的吸液元件和嵌入在所述吸液元件一端的发热元件。
请参阅图10，实施例五的电子烟500包括壳体510、储液器520、雾化组件530，和电源组件540。储液器520，雾化组件530和电源组件540收容在壳体510内。电源组件540用于给雾化组件530提供电源。
壳体510大致为圆柱体状，即横截面为圆形，形成用于收容电子烟500的各内部元件的腔体。壳体510由塑胶材料制成。在其他实施例中，在其他实施例中，壳体510的横截面也可以为方形，椭圆形等。壳体510的一端开设有出气孔512，另一端开设有进气孔（图未示）。壳体510呈中空结构。壳体510靠近出气孔512的一端可以设置一过滤吸嘴，用于过滤烟雾中的尼古丁和烟碱等。
储液器520收容在壳体510内，并套设在雾化组件530的外侧。本实施例中，储液器520为圆柱体状，其中部沿轴向开设有与进气孔和出气孔512相通的烟道521。储液器520内部填充有用于存储烟液的储液介质522。储液介质522可以由纤维、泡沫、海绵、泡沫陶瓷、软橡胶或硅树等吸液性较好的材质制成，形成的储液器520的材料可具有弹性，在组装过程中可以通过挤压等外力使储液器520与雾化组件530的表面充分接触。根据浓度平衡原理，存储在储液器520上的烟液可以输送至具有吸液能力的雾化组件530上。
雾化组件530收容在壳体510内。雾化组件530包括支撑件532、吸液元件533和发热元件534。吸液元件533穿设在支撑件132上。
支撑件532呈中空筒状结构并设于烟道521之内。支撑件532的内部形成与烟道521相连通的雾化通道536，用于供气体流通。支撑件532的侧壁上位于中间的位置开设有两个相对设置的贯通孔538，用于支撑并固定吸液元件533。贯通孔538与雾化通道536相通。可以理解，贯通孔538的数量也可以为一个或者两个以上。
请一并参阅图11，吸液元件533的形状大致为与贯通孔538相配合的实心圆柱。因此，吸液元件533的两端可以分别穿设于支撑件532的贯通孔538，并伸入储液器520的内部，从而与储液介质522直接接触。吸液元件533的中部位于雾化通道536内，且具有位于雾化通道536内的雾化表面5332。吸液元件533可采用具有储液、耐温性能的多孔陶瓷材料制成。本实施例中，吸液元件533的吸液面位于吸液元件533的两端，包括其两个端面及部分外圆周面。
发热元件534为嵌入吸液元件533的内部的形状为螺旋管状的发热丝，所述发热丝呈螺旋状环绕吸液元件533的轴线。本实施例中，发热元件534的边缘与雾化表面5332内切（平齐）。发热元件534采用具有弹性的金属或合金等导电材质制成，优选为镍铬合金丝。当发热元件534通电时，发热元件534能够加热吸液元件533，从而使得存储在吸液元件533内部的烟液能够均匀受热而转化为均匀的雾化颗粒（即烟雾），该烟雾可以从雾化表面5332进入雾化通道536，再进入到烟道521，并最后通过出气孔512进入使用者的口中。
请再次参阅图10，电源组件540与发热元件534电连接，用于提供电源给发热元件534。本实施例中，电源组件540包括电极542、导线544和电极固定座546和电池（图未示）。电极542通过导线544与发热元件534电连接。电极542固定在电极固定座546上，电极固定座546开设有气孔548，用于供气流通过。在其他实施例中，电极固定座546也可以省略。
请一并参阅图12和图13，实施例六的电子烟600与实施例五的电子烟500较为相似，包括壳体610、储液器620、雾化组件630，和电源组件640。其区别在于：
（1）储液器620中无需填充储液介质，而是直接装载烟液；
（2）吸液元件633设置于支撑件632上靠近电源组件640的位置；
（3）吸液元件633为圆管状，其内部沿轴向开设有烟液通道635。雾化表面为吸液元件633的外圆周面，吸液面为吸液元件633的内圆周面，即烟液通道635的侧壁。
实施例五的吸液元件533由于主要靠两端吸入存储在储液介质522中的烟液，相对来说导液速度会比较慢。而实施例六中的储液器620直接装液体，同时雾化组件630下移，且在吸液元件633内部沿轴向开设烟液通道634，则可增大与烟液接触面积，同时提高导液速度。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
需要说明的是，本发明的吸液元件上用于吸收烟液的吸液面，及用于设置有发热元件的雾化面的设置方式并不限于上述实施例，所述吸液面的数量可以为一个或多个，所述雾化面的数量亦可为一个或多个。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
