Description

具有气流仓的雾化芯 技术领域
本发明涉及雾化技术领域，尤其是涉及一种具有气流仓的雾化芯。
 背景技术
雾化芯作为雾化器的核心零件，通常包括导液体和发热体，导液体主要作用是传导液体到发热体进行加热雾化，对于用作电子烟的雾化器的雾化芯的主要作用就是传导烟油，加热蒸发烟油。
过往的雾化芯与其它零件组装成雾化器后，雾化芯与其它零件界定出雾化仓以及雾化仓的进出气孔，发热体的发热部加热液体产生气雾，气流将气雾带走；但是这样雾化仓以及雾化仓的进出气孔由雾化芯与其它零件界定出，进入雾化仓和进出气孔的空气气流影响着雾化的效果，气流的多少，流速的快慢，也间接影响着雾化的效果和稳定性。要是雾化芯与其它零件的组装不够精密，或者一致性不好，都会影响雾化芯的雾化的效果。

 本发明的实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。需要理解的是，如果文中出现“上”、“下”、“纵”、“横”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系、以特定的方位构造和操作，仅是为了便于描述本技术方案，而不是指示所指的装置或元件必须具有特定的方位，因此不能理解为对本发明的限制。还需要说明的是，除非另有明确的规定和限定，如果文中出现“安装”、“相连”、“连接”、“设置”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。当一个元件被称为在另一元件“上”或“下”时，该元件能够“直接地”或“间接地”位于另一元件之上，或者也可能存在一个或更多个居间元件。如果文中出现术语“第一”、“第二”、“第三”等仅是为了便于描述本技术方案，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量，由此，限定有“第一”、“第二”、“第三”等的特征可以明示或者隐含地包括一个或者更多个该特征。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、技术之类的具体细节，以便透彻理解本发明实施例。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施例中也可以实现本发明。在其它情况中，省略对众所周知的系统、装置、电路以及方法的详细说明，以免不必要的细节妨碍本发明的描述。
参见图1-4，本发明的一种实施方式中的雾化芯，包括发热体2以及用于吸收并传导液体的多孔材料的导液体1，所谓多孔材料（也可称为微孔材料）中分布有众多微孔，实现液体的吸收和传导，例如多孔陶瓷材料；导液体1包括导气部12以及连接导气部12并围绕在导气部12外围的基部11，导气部12与基部11之间的间隙形成气流仓17，导液体1上设有连通气流仓17的进气口15、连通气流仓17的出气口16以及用于与液体接触的进液部位14，发热体2包括通电时产生热量的发热部21以及连接发热部21的用于向发热部21传输电流的电连接部22，发热部21与导液体1接触地设在气流仓17内壁上，电连接部22伸出气流仓17外，以在导液体1的进液部位14接触液体时，导液体1将液体传导到发热部21加热产生气雾，外部气流从进气口15进入气流仓17并将气雾从出气口16带出。其中，多孔材料可以是多孔陶瓷材料。
本发明的雾化芯，通过导液体1的进液部与液体接触，导液体1将液体传导到发热体2的发热部21进行加热雾化成气雾，气流流经雾化面（发热体2的发热部21加热液体产生气雾的部位）将雾化气雾带出。
本发明的雾化芯具有有益的技术效果：
1、由于气流仓17设在多孔材料的导液体1内部，发热体2的发热部21设在气流仓17内，气流的大小、流速和路径主要由导液体1结构决定，不受其它零件以及组装关系的影响，有利于保证雾化效果的一致性。
2、由于导液体1是多孔材料的，所以整个气流仓17内都是多孔材料的，气流仓17内所产生上冷凝液会被导液体1吸收，所以可以有效的降低冷凝液的产生。
3、本发明的雾化芯应用于雾化装置中时，由于气流仓17主要由导液体1的结构决定，导液体1无需与其它零件共同界定出气流仓17，所以雾化装置的结构组成可以减少，组装方便快捷稳定可靠。
本发明的雾化芯可以应用于电子烟的雾化装置中，用于加热雾化烟液。具体的工作过程是，雾化芯的导液体1的进液部位14与雾化装置的烟液接触，导液体1将烟液传导到发热体2的发热部21加热雾化成烟，外部气流从进气口进入，将烟从出气口带出，将供吸烟者吸取。
导液体1优选是一体成型的。
关于雾化芯的气流仓17的结构，可以是任意图形，为了发热体2好成型，气流仓17可为圆环状空间（参见图1-4），也可以为带有棱角的环状空间（参见图5），例如多边形环状的，则发热体2的发热部21包含多个平面状的雾化面，这样发热体2成型一致性好控制，和多孔材料的镶嵌稳定性更好。其他各种形状的雾化面和气流仓17就不再举例。发热体2的发热部21包括至少一条发热线路，发热线路弯曲成环状。
参见图1-4，在一些实施例中，气流仓17中，发热部21、导气部12侧壁和基部11侧壁的形状对应，都呈环状，发热体2的发热部21设在基部11侧壁上，进液部位14设在基部11外侧。进液部位14可为设在基部11外侧的进液凹位。
参见图6-9，在另一些实施例中，气流仓17中，发热部21、导气部12侧壁和基部11侧壁的形状对应，都呈环状，发热体2的发热部21设在导气部12侧壁上。可理解地，气流仓17中，导气部12和基部11侧部上可都设有发热部21。进液部位14为设在导气部12外侧的进液凹位。
优选地，基部11包括第一部分111和第二部分112，第一部分111和第二部分112分别围绕导气部12的相反两侧，第一部分111和第二部分112的一端相互连接并连接导气部12。
优选地，进气口15设在基部11与导气部12连接处。
优选地，第一部分111的另一端与第二部分112的另一端分开悬空并界定出出气口16。
优选地，进气口15设在导液体1的下侧，导液体1包括与基部11和/或导气部12连接的向下凸出的用于抬高进气口15的支撑部13，作用之一是支撑雾化芯，再就是可以架高雾化芯，露出进气口15。导气部12可以使得从进气口15直升进入的气流向两边雾化面移动，导气部12分也是由多孔材料制作而成，气流仓17中的雾化气雾不容易冷凝，即使冷凝，冷凝液可以被导液体1再吸收。
综上，本发明的雾化芯具有有益的技术效果：
1、由于气流仓17设在多孔材料的导液体1内部，发热体2的发热部21设在气流仓17内，气流的大小、流速和路径主要由导液体1结构决定，不受其它零件以及组装关系的影响，有利于保证雾化效果的一致性。
2、由于导液体1是多孔材料的，所以整个气流仓17内都是多孔材料的，气流仓17内所产生上冷凝液会被导液体1吸收，所以可以有效的降低冷凝液的产生。
3、本发明的雾化芯应用于雾化装置中时，由于气流仓17主要由导液体1的结构决定，导液体1无需与其它零件共同界定出气流仓17，所以雾化装置的结构组成可以减少，组装方便快捷稳定可靠。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改、组合和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
