Description

雾化芯及其电子雾化装置 技术领域
本发明涉及电子雾化技术领域，尤其涉及一种雾化芯及其电子雾化装置。
 背景技术
目前应用在电子雾化领域的雾化芯，一般包括发热体和导液体，导液体一般为平板状导液体、槽状导液体以及筒状导液体，设置相对应的发热体与之匹配，平板状导液体、槽状导液体的设置使得雾化气体一般是由导液体底部沿着导液体的侧壁向上流通，筒状导液体的设置一般使得雾化气体是沿着筒状内壁径直向上流通的，这样容易导致烟油被加热时产生炸油现象，直通式的气流通道很容易将炸油或者雾化的较大的气雾颗粒通过抽吸时的气流吸入到嘴里，造成不好的体验，且这样的设置导致无法形成一个相对密闭的雾化仓，使得雾化面周围的空间较为广阔，形成的雾化气体无法汇聚变得浓郁，并且进气口与雾化区域直通式设置导致出气口普遍处于较低的位置，容易导致进气端漏油。

实施例1，如图1-图9所示，一种雾化芯，包括上盖100、底座300，上盖100和底座300之间设有加热雾化组件200、电极400，加热雾化组件200包括发热体21和导液体22，发热体21贴附或镶嵌在导液体22外壁面，发热体21包括发热线路212与电极连接件211，电极400与发热体21的电极连接件211连接，电极400给发热体21供电，发热体21的发热线路212的形状与导液体22的外壁形状相匹配一致，使得发热体21可贴合或嵌接在导液体22外壁，进一步，发热体21发热线路212上还可以设有固定件，固定件镶嵌在导液体22内，使发热体21固定在发热体21外壁上，防止发热体21与导液体22接触不好导致的雾化效果不佳，影响雾化效果；导液体22内设有贯通导液体22底部与顶部的雾化通道221，这意味着导液体22的雾化区域在导液体22外壁，雾化通道221在导液体22内，使得在雾化面225形成的雾化气体气流方向是先向下汇集至雾化通道221底部的进气端，此时雾化通道221进气端的雾化气体较为浓郁，口感会更丰富，雾化气体再由雾化通道221的进气端流至雾化通道221的上方的出气端，雾化气体的整个气流走向是迂回的，这样避免了炸油或者大颗粒雾化颗粒被吸入嘴中；底座300内设有用于容置加热雾化组件200的安装槽31，加热雾化组件200可以完全容置于安装槽31，也可部分容置于安装槽31内，通过上盖100、安装槽31与加热雾化组件200之间配合形成封闭的雾化仓500，因为上盖100、安装槽31、加热雾化器之间的紧密配合，此时形成的雾化仓500体积较小，这样使得在雾化气体在雾化仓500内汇集，雾化仓500内的雾化气体越来越浓郁，雾化仓500与雾化通道221联通，使排出至雾化通道221内的雾化气体更浓郁，口感更佳；安装槽31与底座300壁面之间设有进气通道32，该进气通道32与安装槽31上部设置的第一进气口33和底座300上设置的第二进气口34联通，可以理解的，空气由底座300上的第二进气口34进入至安装槽31与底座300壁面之间的进气通道32，再经安装槽31上部的第一进气口33进入安装槽31内的雾化仓500，这样的设计使得气体的进气气流走向也并非直通雾化通道221的，先经过一个径向-轴向-径向的过程，继而有一个径向流动的过程，这样设置抬高了进气的位置，防止冷凝液或烟液流至进第一进气口33。
雾化芯工作过程：雾化芯工作时，空气由第二进气口34进入气流通道，经第二进气口34流至雾化仓500，发热体21发热将导液体22内的烟液雾化，雾化形成雾化气体，雾化气体与雾化仓500内的空气形成气溶胶，气溶胶汇集至雾化通道221，经雾化通道221流出雾化芯，最终被吸食者吸食。
导液体22为上大下小的锥台结构，锥台结构可以为曲面锥台，例如可以是倒置的圆锥台或椭圆锥台结构，其底面为圆形或者椭圆形，外壁面为曲面形状，即雾化面225为曲面，导液体22还可以是倒置的棱锥台结构，棱锥台的底面形状可以是三角形、四边形、五边形等多边形，其侧面为多个四边形围合的结构，即雾化面225为多个四边形围合而成的棱锥结构，具体形状不做限定，发热体21环绕导液体22外表面设置，且为上大下小的、可与导液体22贴合或嵌接的筒状结构，发热体21的形状与对应的导液体22的外壁面形状相匹配一致，意味着导液体22的雾化面225也是上大下小的锥台形状，雾化面225往雾化通道221方向的面积越来越小，发热体21能贴附或镶嵌在导液体22外壁面，第一进气口33是设置在安装槽31上部的，即气流先流经导液体22直径更大的一端，气流沿着上大下小的锥台形的雾化面225向下流，流至雾化通道221，随着气流方向雾化面225积渐小，雾化区域气流通道随着气流方向渐小使得雾化气体较为聚集、较为浓郁，口感更丰富，还可以保证雾化面225各处的烟油被充分利用。
当然导液体22也可以是圆筒状结构，如图5-图6所示，发热体21环绕导液体22外表面贴附或嵌接，且也为圆筒状结构，即雾化面225也为曲面，发热体21加热雾化雾化面225上的雾化液，另外，在圆筒状的导液体22顶面还设置有进液孔229，进液孔229可设置一个，也可设置多个，多个进液孔229还可以连通起来形成圈状，进液孔229与上盖100开设的进液口14连通，雾化液由进液口229流入导液体22，雾化面225向雾化通道221的进气端方向每一处的面积保持一致，气流先流经圆筒状导液体22上端，气流沿着圆筒状的雾化面225向下流，流至雾化通道221，使得雾化面上每一处都能均匀雾化，口感更细腻，并且实际生产过程中，圆筒状结构更易实施，导液体22成品的均匀性、一致性也能更好。
雾化通道221可以在导液体22的轴向中心设置，也可以偏离中心设置，可以与中心轴平行，也可以倾斜设置。同时意味着雾化通道221的进气端设置在导液体22的底部，雾化气体需顺着雾化面225向下流动再沿着雾化通道221向上流通，雾化气体经过迂回后，使得雾化大颗粒和炸油时产生飞溅的烟油颗粒不容易吸入到用户口中，并且这样设计使得中间的雾化导气管相对于现有的雾化导气管较长，冷凝液不容易沿着雾化导气管爬升到用户口中。
如图1-图2所示，导液体22顶面设有槽体222，导液体22的进液面224为槽体222内壁，槽体222可以是多边形槽，也可以是曲面槽，槽体结构的导液体22可以增大导液体22的进液面224积，进液面224与上盖100开设的进液口14联通，槽体222内还可以储存一部分雾化液，缩短进液面224至导液体22雾化面225的距离，加快导液体22的导液速度，可以将槽体222内壁到达相对应的雾化面225的距离设计为一致或相近，这样可以使得每一处的导液体22的进液速率相差不大，可进一步提升雾化口感。导液体22顶面除了上述槽体222结构，还可以是平面结构、凸面结构和凹面结构。
如图1-图2所示，导液体22的雾化通道221上方设有用于联通雾化通道221和雾化导气管的连接管23；根据导液体22顶面结构不同，连接管23的位置不同。导液体22顶面为槽体222时，，雾化通道221位于槽体222底部，连接管23抵压在雾化通道221上方的槽体222壁面上并形成密封，连接管23与导液体22可以为单独的结构，导液体22的槽体222底部可以为平面结构，也可以是其他结构，只需在槽体222底部的雾化通道221出口位置周边设有可以与连接管23抵接密封的位置即可。本实施例中，连接管23抵压在平面的槽体222底面上并形成密封，将槽体222底部设计为平面是为了更好的实现连接管23与导液体22的密封，槽体222侧壁与连接管23之间形成储液空间，储液空间内储存烟液；当然导液体22顶面还可以是非槽体222，如平面结构、曲面结构，形成平面结构或曲面结构的进液面224，连接管23抵压在雾化通道221上方的平面或曲面的进液面224上并形成密封；连接管23与导液体22抵接并形成密封，防止了烟液由连接管23处进入雾化通道221，避免未经雾化的烟液被使用者吸食，雾化通道221内的雾化气体最后经雾化导气管导出；，连接管23与导液体22还可以是一体成型，先将浆料浇铸在模具上形成导液体22，模具上留有连接管23的模型，往模型上继续浇铸浆料，形成连接管23，一体结构的设置使得减少开模次数，同时还节省了组装步骤。
第一进气口33为安装槽31上部设置至少一个进气槽或进气孔，空气经由第一进气孔进入雾化仓500，与雾化仓500内的雾化气体形成气溶胶；进气槽或者进气孔可以设置一个，进气槽或者进气孔也可以设置多个，多个进气槽或者进气口可以呈规律排布，也可以呈不规律排布，由于第一进气口33是设置在安装槽31的上部，且加热雾化装置又容置在安装槽31内，空气由安装槽31上部进入雾化仓500内，相当于抬到了雾化仓500的进气端，使得在使用过程中，冷凝液或者漏油都不易发生在第一进气口33处。
第二进气口34为设置在安装槽31外侧的底座300底面上或底座300侧壁上的至少一个进气孔，进气孔可以设置多个，多个进气孔可以是不连续的设置在底座300底面上或底座300侧壁，多个进气孔可以是连续的设置在底座300底面上或底座300侧壁，空气由第二进气口34进入安装槽31与底座300壁面之间的进气通道32，给第一进气口33供气。
导液体22顶部向外延伸有凸沿223，凸沿223的形状大小与安装槽31槽口的形状大小相匹配，使得凸沿223的顶面与安装槽31的顶面齐平，凸沿223的侧壁抵接安装槽31侧壁，部分上盖100与安装槽31相抵接，这样设置可更好的形成密封的雾化仓500；当然凸沿223的顶部可以略低于安装槽31的顶部，使整个导液体22容置于安装槽31内；还可以是凸沿223的顶部高于安装槽31的顶部，此时凸沿223的侧壁抵接上盖100，安装槽31的顶部抵接在凸沿223的下方，从而使上盖100、安装槽31、加热雾化组件200形成雾化仓500。
如图7-图8所示，导液体22的进液面224上开设有多个槽体222，槽体222的设置可使得进液更均匀、更充分，导液体22的凸沿223可向下延伸形成一圈固定件228，固定件228与安装槽31底部抵接，固定件228可采用多孔材质制成，固定件的设置是为了固定、限位加热雾化组件200，防止将加热雾化组件200组装到底座300的安装槽31时发生歪斜，固定件228的外壁面与安装槽31的内壁面密封接触，使得加热雾化组件228与安装槽31更紧密，固定件228上设有与安装槽31上的第一进气口33连通的气流口2280，使雾化芯内保持气流通畅，固定件228的设置还可给导液体22提供支撑强度，同时起到隔热效果，有效减少雾化仓500内的热量外溢，其多孔材质还可吸收冷凝液，起着回收冷凝液的作用；且发热体21的电极连接件211贴附在导液体22的凸沿223下从安装槽31伸出与电极400连接，此时上盖100与底座300密封，底座300侧壁与安装槽31之间留有进气通道32，即电极连接件211延伸至进气通道32内，电极400由底座300底部穿设在进气通道32内，上盖100上设有电极安装孔11，电极400与发热体21的电极连接件211电连接，且电极400的顶端插接在电极安装孔11内，电极400将电极连接件211并将电极400插接至上盖100的电极安装孔11内，实现电极400与电极连接件211连接、与上盖100的固定，从而给发热体21供电。
导液体22底部设有用于支撑加热雾化组件200的支撑件24，支撑件24间隔设置至少一个，即可以设置一个，也可以间隔设置多个，支撑件24还可以是设置一圈。支撑件24为多孔结构，导液体22与支撑件24可为一体成型结构，支撑件24具有较高的强度结构，可以给加热雾化组件200提供结构支撑，防止导液体22受到发热体21的持续高温的影响，且其多孔结构可起着吸收冷凝液的作用，支撑件24部分抵接至安装槽31底部，将雾化仓500内的形成的冷凝液尤其是安装槽31底部形成的冷凝液回收至导液体22，支撑件24之间留有雾化仓500与雾化通道221联通的气流通道，使得在雾化面225内形成的雾化气体可经气流通道到达雾化通道221；或者支撑件24设置一圈，支撑件24上留有雾化仓500与雾化通道221联通的气流通道，一圈支撑件24中部分可抵接至安装槽31底部，部分不抵接安装槽31底部以形成雾化仓500与雾化通道221联通的气流通道，这样支撑件24起着回收冷凝液至导液体22的作用，还起着给予导液体22强度支撑的作用。
上盖100优选为软性结构，优选软性的硅胶结构，上盖100与底座300配合将加热雾化组件200密封，防止其漏油，其外侧设有至少一圈密封凸沿12，可以设置一圈密封凸沿12，也可以设置多圈密封凸沿12，密封凸沿12的设置是为了使上盖100与雾化外壳紧密配合，防止外壳内的储液仓内的液体经上盖100侧壁渗漏。
上盖100内壁设有定位件13，定位件13可为一圈沿上盖100内壁周向排布的凸出，安装槽31顶部设有定位槽35，定位槽35为一圈沿安装槽31顶部周向排布的凹槽，凹槽与凸出相匹配以使定位件13与定位槽35插接固定，实现底座300与上盖100的定位固定，防止底座300在上盖100内左右晃动，从而影响密封效果，避免影响到加热雾化组件200的雾化效果；可设计定位槽35的长度长于定位件13的长度，使定位槽35与定位件13插接固定后，在定位槽35内还留有空隙，此时该空隙将成为第一进气口33，这样第一进气口33就不需要另外设计了，使得结构更简单，当然第一进气口33也可另外设置于安装槽31上。
实施例2，如图10-图12所示，一种电子雾化装置，包括外壳10，在外壳10内设置有储液仓、雾化导气管30，储液仓下方设有实施例1中的雾化芯50；雾化芯50的雾化通道221与雾化导气管30联通，雾化通道221与雾化导气管30联通，储油仓20内储存的雾化烟油给雾化芯50供油，雾化芯50内形成的雾化气体与空气形成气溶胶，气溶胶经雾化通道221流至雾化导气管30，最终导出至外壳10，气溶胶被使用者吸食。
电子雾化装置其他部件采用现有技术，在此不再赘述。
