Description

雾化芯、雾化组件及电子烟 技术领域
本发明涉及电子烟技术领域，尤其是涉及一种雾化芯、雾化组件及电子烟。
背景技术
参见图1，目前，现有电子烟的雾化芯包括芯主体10，芯主体10包括沿纵向延伸的气道30，在气道30内设置加热元件20，芯主体10包括外壁以及与气道相对应的内壁，外壁用于吸收烟液，烟液从外壁渗透至内壁后由加热元件20加热产生烟雾，烟雾在气道30内由气流从下向上带出。
目前，加热元件20多设计在气道30的中部区域B，气道的两端会预留一部分空白区域，设为上部区域A和下部区域C，雾化芯雾化烟液时产生烟雾则集中在中部区域B，烟雾从雾化芯流出需要经过雾化芯内与A对应的部分通道，雾化芯内的气道30一般较狭窄，因此烟雾经过与A对应的部分通道会影响烟雾流出速度和烟雾流出量，进而会影响用户抽吸时的口感，同时因烟雾流出速度受影响导致容易在气道内积聚冷凝液。
另外，芯主体10的外壁一般是仅留有部分区域露出用于进油，并作为进油区域，进油区域通常是与加热元件20相互对应，因此进油区域会设在芯主体10的中部区域B。芯主体10外包覆壳壁40，壳壁40上开设进油孔41，进油孔41用于露出芯主体10上的进油区域。壳壁40沿纵向延伸围合形成雾化通道42，雾化通道42与气道30相连通。当用户抽吸时，在气流压强的作用下，芯主体10内的烟油会向上爬升，向芯主体10的中部区域B和上部区域A爬升，加热元件20会加热消耗芯主体10中部区域B内烟油；当用户不抽吸时，位于芯主体10上部区域A内的烟油会在重力作用下蔓延至中部区域B，减弱了“进油孔41”区域的进油动力，再次抽吸时无法进入充足的烟油导致出现干烧的情况。

本发明第二方面还提供一种雾化组件，包括上述的雾化芯。
作为一种实施方式，所述雾化组件还包括储油器，所述储油器内形成有储油腔，所述雾化芯伸入所述储油腔内。
本发明第三方面还提供一种电子烟，包括雾化组件和电芯组件，所述雾化组件包括前述雾化芯,所述电芯组件为所述雾化芯的加热元件供电。
实施本发明的雾化芯、雾化组件和电子烟，具有以下有益效果：本发明的雾化芯通过将加热元件设计在芯主体的气道的下游，气流从气道的上游流向下游并将加热烟油产生的烟雾带出，烟油在气道的下游被加热产生的烟雾会直接流出气道，不受气道的限制，保证了烟雾流出速度和烟雾流出时的爆发力，极大地提高了口感，同时因烟雾直接流出芯主体的气道而不受狭窄气道限制，提高了烟雾流入用户口中的速度，减少了烟雾的停留时间，进而降低烟雾形成冷凝液的机率；另外，用户在抽吸时，雾化芯的芯主体吸收的烟油在气流压强的带动下与气流同方向朝向下游的加热元件的方向聚集，提高烟油集中供应量，进而加大了雾化量；用户在未抽吸时，由于芯主体的大部分烟油都被消耗，烟油可以无阻力地渗透进芯主体内，且在重力作用下快速渗透至芯主体各个位置。

具体实施方式
以下将结合附图及实施例来详细说明本公开的实施方式，借此对本公开如何应用技术手段来解决技术问题，并达成技术效果的实现过程能充分理解并据以实施。需要说明的是，只要不构成冲突，本公开中的各个实施例以及各实施例中的各个特征可以相互结合，所形成的技术方案均在本公开的保护范围之内。
需要说明的是，本申请的说明书中记载了大量的技术特征，分布在各个技术方案中，如果要罗列出本申请所有可能的技术特征的组合(即技术方案)的话，会使得说明书过于冗长。为了避免这个问题，本申请上述发明内容中公开的各个技术特征、在下文各个实施方式和例子中公开的各技术特征、以及附图中公开的各个技术特征，都可以自由地互相组合，从而构成各种新的技术方案(这些技术方案均因视为在本说明书中已经记载)，除非这种技术特征的组合在技术上是不可行的。例如，在一个例子中公开了特征A+B+C，在另一个例子中公开了特征A+B+D+E，而特征C和D是起到相同作用的等同技术手段，技术上只要择一使用即可，不可能同时采用，特征E技术上可以与特征C相组合，则A+B+C+D的方案因技术不可行而应当不被视为已经记载，而A+B+C+E的方案应当视为已经被记载。
参见图2-5，本公开一方面的实施例提供一种雾化芯1，包括芯主体10和加热元件20，所述芯主体10内形成有用于气流通过的气道30，所述加热元件20沿气流流向(箭头方向)位于所述气道30的下游位置。其中，本文中出现的“下游”是相对于“上游”的位置，参见图2和图4，气道30沿纵向延伸，气流流向是从下往上走，将加热元件20加热烟油产生的烟雾从下往上带出，即从“上游”走向“下游”。因此加热元件20沿气流流向位于所述气道30的下游位置中的“下游”相当于图1中气道30的上部，即加热元件20设在气道30的上部，气流从气道30下端流进，从气道30的上端流出。
参见图2和图4，雾化芯1通过将加热元件20设计在气道30的下游，气流从气道30的上游流向下游并将加热烟油产生的烟雾带出，烟油在气道30的下游被加热产生的烟雾会直接流出气道30，不受芯主体10内的气道 30限制，保证了烟雾流出速度和烟雾流出时的爆发力，极大地提高了口感；另外，用户在抽吸时，雾化芯1的芯主体10吸收的烟油在气流压强的带动下与气流同方向聚集流向位于下游的加热元件20，提高烟油集中供应量，进而加大了雾化量；用户在未抽吸时，由于芯主体10内的大部分烟油都聚集至加热元件20被消耗，烟油可以无阻力地渗透进芯主体10内，且在重力作用下快速渗透至芯主体10各个位置，同时因烟油消耗充足再进油时可以避免过剩的烟油漏出。
其中，加热元件20具有从芯主体10内伸出的导电引脚21。
芯主体10是多孔材料制成的，多孔材料包括但不限于陶瓷、云母、棉、纤维等，优选采用结构固定的芯主体，如陶瓷、云母等；加热元件20是由导电金属制成的，包括但不限于铜、银、铝、钨或合金等。加热元件20在另一些实施例中可以是含碳材料的导电材料制成的，如碳纳米材料、石墨烯等。加热元件20在另一些实施例中还可以是导电油墨等等。
参见图5，在一些实施例中，所述气道30包括相连通的第一通道31和第二通道32，所述第二通道32相对于所述第一通道31扩宽，且所述第一通道31沿气流流向连接在所述第二通道32的下游。其中，参见图5，气流流进第二通道32，从第二通道32流向第一通道31，再从第一通道31流出，也就是说气流从第二通道32的上游流向第一通道31的下游。第一通道31沿气流流向连接在所述第二通道32的下游相当于图1中第一通道31连接在第二通道32的上端。
第二通道32相对于第一通道31扩宽，加热元件20上爬升的烟油或烟油雾化后产生的冷凝液在扩宽的第二通道32可以及时分散疏通，避免堵油。尤其是对粘稠性烟油，防堵油效果更好。
参见图2和图4，在一些实施例中，所述加热元件20位于所述第一通道31，进而实现加热元件20位于芯主体10内的气道30的下游，将加热元件20直接定位在第一通道31，方便生产制备时的定位要求。在另一些实例中，加热元件20还可以一部分沿气流流向位于第二通道32的下游，即位于图5中的第二通道32的上部，也就是说另外一种情况是加热元件20不仅位于第一通道31，同时还位于第二通道32的下游位置。
如图2和4所示，在一些实施例中，所述加热元件20分布在所述芯主体10与所述第一通道31相对应的内壁11，所述加热元件20至少部分地埋入所述内壁11内，使加热元件20尽量多地与烟油直接接触，在内壁11内埋入的加热元件20越多，则加热元件20越可以避免干烧；另一种情况是加热元件20在内壁11外凸出的部分越多，加热元件20露出的面积越大，爬升至加热元件20上的烟油露出的就越多，加热后产生的烟雾直接散出的就越多越快，瞬间产生的烟雾量就会越大，口感会越好。其中，内壁11可以设有用于埋设加热元件20的槽，以加热元件20由加热丝构成为例，加热丝的线径可以与槽的深度相同，加热丝在槽内裸露出部分表面；加热丝的线径也可以大于槽的深度，加热丝从槽内凸出一部分；加热丝的线径也可以小于槽的深度，加热丝完全埋入内壁，其中加热丝在该情况下可以被封闭埋入或未被封闭埋入。
在另一些实施例中，所述加热元件20位于所述内壁11外并与所述内壁相接触，也就是说，加热元件20未埋设在内壁11内，加热元件20露出的表面积较大，爬升至加热元件20上的烟油加热产生的烟雾可以快速在气道30内被抽吸的气流带入用户口中，烟雾量大。
在优选实施例中，加热元件20一部分埋入内壁11，另一部分凸伸出来，在避免干烧的同时保证较大的烟雾量。
如图2-4所示，在一些实施例中，所述加热元件20沿所述第一通道31的延伸方向呈螺旋分布。即加热元件20整体为螺旋状的。在另一些实施例中，加热元件20也可以是网状，或者轨迹状的丝或轨迹状的片分布在第一通道31内。加热元件20也可以是导电油墨印刷形成的导电轨迹。
如图2所示，在一些实施例中，芯主体10包括外壁12，所述外壁12设有用于露出的进油区域。其中，该外壁12是与内壁11相对应的，该进油区域是指芯主体10上用于进油的位置，烟油从该进油区域的位置进入芯主体10，并向芯主体10内的周围渗透扩散。
在一些实施例中，进油区域设在芯主体10与加热元件20相对应的外壁位置。具体地，进油区域设在所述芯主体10与所述第一通道31相对应的外壁12位置。在一些实例中，该进油区域可以是芯主体10与第一通道 31相对应的外壁12的全部区域，例如在该全部区域外包覆吸油棉助力吸油；在另一些实例中，该进油区域可以是芯主体10与第一通道31相对应的外壁12的局部区域，参见图2，例如雾化芯1包括壳壁40，所述壳壁40包覆在所述芯主体10的外周，所述壳壁40上开设有进油孔41，所述芯主体10从所述进油孔41露出的部分作为进油区域，所述进油孔41设所述壳壁40与所述第一通道31相对应的位置。
通常情况，进油孔41设在壳壁40与加热元件20相对应的位置，参见图1，现有技术芯主体10包括上部区域A、中部区域B和下部区域C，加热元件20设在与中部区域B相对应的位置，壳壁40上开设的进油孔41与加热元件20一样基本位于芯主体10的中部区域B位置，当用户抽吸的时候，芯主体10下部区域C的烟油在气流压强的带动下与气流同方向朝向加热元件20的方向聚集，因此芯主体10与加热元件20相对应的中部区域B的烟油和下部区域C的烟油可以被加热雾化；当用户不抽吸的时候，芯主体10的上部区域A的烟油就会在外部压强和重力的双重作用下朝向中部区域B蔓延，进而堵塞进油孔41，给进油造成阻力，导致外界进油慢，影响进油速度，容易发生干烧。参见图2和图4，因加热元件20相对现有技术向上移位，进油孔41也随着向上移位。用户抽吸时，加热元件20将芯主体10内位于上部区域A的烟油加热雾化后，外部烟油可以无阻力的在进油孔41进油，解决堵油造成干烧的问题。尤其是对粘稠性的烟油，防堵油效果更好。另外，现有技术中也有将加热元件20从芯主体10内的气道30的一端延伸至另一端，爬升在加热元件20上的烟油或产生的冷凝液容易堵油。
在一些实施例中，加热元件20朝向气流流向下游的一端延伸至芯主体10的端部。可以理解的是，加热元件20的一端与芯主体10的端部可以相当于平齐，也可以相当于无限接近端部。通过该设计，防止进油区域堵油的效果更佳。还可以理解的是，加热元件20朝向气流流向下游的一端与芯主体10的端部之间存一些距离，但距离较小，仍然可以防止进油孔41堵油，也不影响排烟速度等。
参见图2和图4，在一些实施例中，所述加热元件20包括至少一根发 热丝，每一根发热丝相互并联。其中，发热丝的数量可以为一根，也可以为多根。当发热丝为多根时，该多根发热丝可以并联，以减少电阻，增加功率，以增加烟雾量。
下面通过具体实施例进行详细说明。

气道30包括第一通道31和第二通道32，第二通道32连接在第一通道31的下端并相对于第一通道31扩宽。第一通道31的下端相对于芯主体10与第二通道32相对应的内壁11凸出。在本实施例中，第一通道31和第二通道32的横截面为圆形，第二通道32的内径大于第一通道31的内径。在其它实施例中，第一通道31和第二通道32的横截面的形状可以相同，也可以不同，分别可以为矩形、三角形、菱形、平行四边形、椭圆形、半圆形等，也可以为超过四条边的多边形等。
其中，加热元件20包括两根发热丝，两根发热丝在两端处并联，并联的两端连接有导电引脚，从芯主体10穿出。两根发热丝相互并列并呈螺旋状沿芯主体10与第一通道31相对应的内壁11延伸，两根发热丝朝向气流流向下游的一端延伸至芯主体10的端部。发热丝沿横向的一部分埋入芯主体10的内壁内，发热丝横向的另外一部分凸伸出来。

参见图6，本发明第三方面还提供一种电子烟，包括上述的雾化组件和用于为加热元件20供电的电芯组件，其中，电芯组件包括电池等电器元件。
