 背景技术

并且，电加热丝41和导液棉绳42在工作时，由导液棉绳42的两端进液体，导液棉绳42将液体传导到电加热丝41，气流从电加热丝41下方向上，将加热雾化的蒸汽带出。由此产生的问题是：1.其进液方式较为单一，难以根据不同的要求采用其它进液方式。2.其加热方式为周向发热，但是电加热丝41底部下方进入的为常温空气温度较低，电加热丝41顶部的为雾化后的蒸汽，温度较高，很难保证雾化区域的温度均匀，因此体验较差，容易出现积碳和糊芯等问题，影响用户体验。

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3-11，本发明的第一种实施方式中的雾化单元1，包括支架12以及设在支架12上的片状的发热体11，发热体11包括发热部111、电极部112和固定部113，发热部111的第一方向a上的两边同向地向第三方向c上的弯，以使发热部111的在第三方向c上的一侧内凹而另一侧拱起，发热部111包括与电极部112电性连接的发热线路1111，以在电极部112通电时发热线路1111产生热量；所述固定部113嵌入所述支架12中至少两个固定部113设在发热部111和/或电极部112的在第一方向a和/或第二方向b上的两边边缘；
支架12上设有向第一方向a敞开的腔体12a、供气体进入的进气口12b以及供气体流出的通气口12c，进气口12b与通气口12c相连，发热体11设在支架12上，发热部111设在腔体12a的敞开处，固定部113嵌入支架12中，使发热体11与支架12牢固连接；发热部111的内凹一侧朝向腔体12a并与腔体12a界定出用于容纳导液体21和使导液体21与发热体11接触的容纳仓13，支架12上设有通向容纳仓13的进液孔12d，以供液体进入容纳仓13；发热部111的拱起一侧朝向外并与进气口12b的进气方向正对，发热部111的第一方向a上的两边与通气口12c对应，以供气流正面吹向发热部111的拱起一侧并经发热部111的第一方向a上的两边流过；
第一方向a、第二方向b和第三方向c两两不相互平行，优选地，第一方向a、第二方向b和第三方向c两两相互垂直。
从而在容纳仓13中设有导液体21并将来自进液孔12d的液体传导到发热体11时，发热体11将液体加热雾化，进而雾化气体被进入进气口12b的气流带走。
该雾化单元1的容纳仓13中可设置导液体21，导液体21与发热部111的内凹一侧接触，并将进入进液孔12d的液体传导到发热体11进行加热雾化，雾化气体被进入进气口12b的气流带走。
该雾化单元1中，支架12主要作用是为发热体11提供支撑强度，使发热体11不易变形，同时与发热体11界定出容纳导液体21的容纳仓13，并将导液体21压缩紧使导液材料和发热体11直接接触良好。 
  导液体21设置在雾化雾化单元1容纳仓13内，被支架12、发热体11、盖体124从四周限制压紧，起到传导液体21的作用。
进液孔12d的大小可以限制进入到导液棉上的液体的量，可以有效的防止因为进液过多造成的漏液问题。
由于发热部111不再是周向覆盖的，所以可以根据要求采用不同的进液方式，将进液孔12d设在不同位置，例如可以设在发热体11的第二方向b上的两端；也可以设在发热体11的内凹一侧对着的位置。
发热体11的拱起一侧和气流流动更加匹配，可以使得雾化面的热量更加均匀。发热体11主要采用铁铬铝、镍铬合金、不锈钢、钛、钛合金、镍铁合金等常用的电热合金金属片，通过切割、腐蚀等工艺形成电加热电路。再通过模具或者治具整形，形成具有上述形状的加热体。导液体21可采用多孔导液棉或导液棉绳。
参见图20，在一些实施例中，发热部111的第一方向a上的两边向第三方向c弯，使得发热部111呈弧形，由于弧形具有平缓的过度面，所以与气流的流动更加贴合。
参见图21-23，在另一些实施例中，发热部111的至少一处沿第二方向b的轴线弯折，以使发热部111的第一方向a上的两边向第三方向c弯。具体而言，在图21的实施例中，发热部111的中间沿第二方向b的轴线弯折成直角或钝角，以使在轴线两侧的部分向第三方向c弯，发热部111的中间沿第二方向b的轴线弯折的角度α为直角或钝角钝角标识，具体而言，可以弯折成V形。在图22-23的实施例中，发热部111的第一方向a上的两边分别沿第二方向b的轴线弯折；这里角度β又可以有不同的设计，在图22的实施例中，发热部111的第一方向a上的两边分别沿第二方向b的轴线弯折的角度β可以是直角，发热部111弯折呈矩形状；在图23的实施例中，发热部111的第一方向a上的两边分别沿第二方向b的轴线弯折的角度β可以是钝角，发热部111弯折呈矩形状。
参见图20，电极部112的第一方向a上的两边也向第三方向c的一侧弯，并且与发热部111的第一方向a上的两边的弯的形状和程度相同。
参见图20，固定部113的数量优选为多个，每一固定部113包括向外延伸的第一部分1131以及与所述第一部分1131连接的第二部分1132，第二部分1132与第一部分1131外侧边缘连接，第二部分1132朝垂直于或倾斜于第一部分1131延伸方向凸出，固定部113可以呈T形。
参见图20，电极部112包括分别设在发热部111的第二方向b上的两侧的两个电极部112，电极部112向外延伸，延伸方向为平行于第二方向b的方向或与第二方向b成一定角度的方向。在第一方向a上，电极部112的尺寸与发热部111的尺寸相当或小于发热部111的尺寸。
制作好的发热体11可通过模内注塑工艺，和支架12通过模内注塑成型，固定部113嵌入到支架12内部，支架12采用耐高温塑胶制作而成，已知可实施的包括PEEK、LCP、PPS、PI、PA46等等耐高温塑胶。这样雾化加热支架12为发热体11提供非常好的支撑强度，可以方便后续的组装过程中实现自动化生产。
参见图3-6，支架12包括基部121以及在基部121上同向伸出的两个伸出部122，两个伸出部122在第二方向b上间隔设置，发热体11的发热部111设在两个伸出部122之间，两个伸出部122的伸出末端之间的间隔形成进气口12b，两个伸出部122的位于发热部111旁边的部分的间隔形成通气口12c，通气口12c包括分别位于发热体11的发热部111的第一方向a上的两侧的两个通气口12c。发热体11的边缘可以嵌入伸出部122中。基部121与伸出部122优选为一体成型的。
参见图11，电极部112包括分别设在发热部111的第二方向b上的两边的两个电极部112，两边的电极部112分别嵌入两侧的伸出部122中。
参见图3-11，进液孔12d设在与发热部111的内凹一侧对着的位置，位于支架12上部，形成上方进液方式。这样的好处是液体到达发热体11各个部分的路径较为一致，发热体11各个部分供液的塑胶均衡，不会有局部出现供液不足的问题。现有的采用陶瓷材质发热体11的雾化雾化单元1较多采用这种进液方式，所以本发明的雾化单元1可以生产的和此类陶瓷雾化雾化单元1结构大小尺寸相同，则雾化装置3的其余结构可以直接采用此类陶瓷雾化装置3的结构设计，只需要更换雾化组件2就可以得到区别于陶瓷芯的雾化体验，更换起来也不必重新开设模具，可以非常快的对现有技术做切换。
参见图3-11，支架12包括基部121和盖体124，腔体12a设在基部121中，腔体12a的第三方向c上的两侧敞开，以方便后续导液体21和盖体124的装入，发热体11设在下方一侧敞开处，盖体124设在上方的另一侧敞开处，盖体124盖住容纳仓13，进液孔12d设在盖体124上。优选地，进液孔12d的数量为一个或至少两个，通过进液孔12d的数量或大小控制进液效率。
参见图3-11，优选地，容纳仓13的设置盖体124的位置下沉形成用于定位盖体124的内定位台阶12g，盖体124抵住内定位台阶12g，以将导液体21限制在容纳仓13中并且导液体21与发热体11紧密接触。参见图3-11，支架12的外侧有用于定位支架12的外定位台阶12h，当雾化单元1应用于雾化装置3中时，外定位台阶12h与雾化装置3的内部结构配合，实现雾化单元1的定位。
本发明的第二种实施方式的雾化单元，参见图12-19，进液孔12d包括分别设在支架12的第二方向b上的两侧的两个进液孔12d，形成两侧进液方式。进液孔12d优选地与容纳仓13直线贯通，以便于设置导液体21，例如导液棉绳，导液体21的两端可分别位于两个进液孔12d中；或所述进液孔（12d）倾斜地与所述容纳仓（13）贯通，所述第二方向（b）不平行于所述第一方向（a）和所述第三方向（c）。
参见图12-19，支架12包括基部121和腔壁123，腔壁123设在至少两个延伸部之间，腔壁123弯曲形成向第三方向c敞开的腔体12a，至少部分固定部113嵌入腔壁123边缘中。支架12上设有出气孔12e，出气孔12e和发热体11分别设在支架12在第三方向c上的两侧，以供气体流依次流经进气口12b、通气口12c、腔壁123与基部121的间隔以及出气孔12e，带走发热体11加热雾化产生的气雾。支架12包括盖体124，腔壁123上设有贯穿到腔体12a的贯穿孔12f，贯穿孔12f位于发热部111的内凹一侧对着的位置，盖体124穿设在贯穿孔12f中并伸入腔体12a中，以在容纳仓13中设有导液体21时，盖体124挤压导液体21使导液体21与发热体11接触。在图12-19的实施例中，支架12：优选采用耐高温塑胶制成，主要作用是为发热体11提供支撑强度，使发热体11不易变形，同时与发热体11界定出容纳导液体21的容纳仓13，并将导液体21压缩紧使导液材料和发热体11直接接触良好。
参见图12-19，发热体11可采用镂空金属片或者金属丝制成，发热体11的拱起一侧和气流流动更加匹配，可以使得雾化面的热量更加均匀，可以使得雾化面的热量更加均匀。盖体124主要作用是将导液体21压缩紧，使导液体21和发热体11直接接触良好。导液体21可设置在雾化单元1的容纳仓13内，起到传导液体21的作用。当进液孔12d与容纳仓13直线贯通时，导液体21可穿设在容纳仓13和进液孔12d中，其在第二方向b上的两端是未被限制的。
图12-19的实施例，在支架12的第二方向b上的两端也即左右两端设置进液孔12d，发热体11采用模内注塑成型的方式使得固定部113嵌入到塑胶支架12内，使得发热体11具有较好的支撑强度，在将导液体21穿设在发热体11和支架12形成的容纳仓13内。这样做由于导液体21例如导液棉绳是穿设在容纳仓13中的，要想导液体21顺利的穿设在容纳仓13中，导液体21没法设置非常粗，要不然无法顺畅的穿过容纳仓13，而导液体21若设置得较细，可以顺畅穿过容纳仓13又会出现有发热体11和导液体21接触不好的问题产生，因此在支架12的第一方向a上的一侧也即上方，有开设贯穿孔12f，在贯穿孔12f上设置盖体124，使得装入的盖体124压紧压缩导液体21，使得导液体21和发热体11能够接触得良好，从而解决发热体11和导液体21接触不好的问题。
在上述实施方式中，支架12优选是塑料材质的，发热体11与支架12模内注塑方式结合，也即将发热体11放在注塑模具中，然后注塑形成支架12，支架12即与发热体11结合。
综上，本发明的雾化单元1的发热体11的强度好，易于大批量自动化生产，且较传统的平面状加热体雾化面积更大，和雾化的气流方向更加匹配，加热过程中热量更加均匀。并且该雾化单元1可以应用于电子烟中，导液体21将烟液传导到加热体进行加热雾化。
参见图16-19，本发明的一种实施方式的雾化组件2，包括导液体21以及根据权利要求1-25任一项的雾化单元1，导液体21设在雾化单元1的容纳仓13中并与发热体11接触，以将来自进液孔12d的液体传导到发热体11进行加热雾化。
该雾化组件2由于采用上述的雾化单元1与导液体21组合，导液体21设置在雾化雾化单元1容纳仓13内，被支架12、发热体11、盖体124从四周限制压紧，起到传导液体21的作用；发热体11的拱起一侧和气流流动更加匹配，可以使得雾化面的热量更加均匀；支架12为发热体11提供支撑强度，使发热体11不易变形，同时与发热体11界定出容纳导液体21的容纳仓13，并将导液体21压缩紧使导液材料和发热体11直接接触良好；由于发热部111不再是周向覆盖的，所以可以根据要求采用不同的进液方式，将进液孔12d设在不同位置，例如可以设在发热体11的第二方向b上的两端；也可以设在发热体11的内凹一侧对着的位置；发热体11不再是通过人工在导液体21外周缠绕电加热丝制成，而可以通过模内注塑工艺，发热体11和支架12通过模内注塑成型，固定部113嵌入到支架12内部，可以方便后续的组装过程中实现自动化生产。
参见图24-29，本发明的一种实施方式的雾化装置3，包括外壳31以及设在外壳31中的根据权利要求26的雾化组件2，外壳31中设有储液仓313、出气通道312以及进气通道311，储液仓313用于存储液体并与雾化组件2的进液孔12d连通，进气通道311与雾化组件2的进气口12b相通，出气通道312与雾化组件2的通气口12c相通，以供气体依次经进气通道、进气口12b、发热体11、通气口12c和出气通道312，将发热体11加热雾化而成的气体带出。具体而言，图24-26的实施例中，雾化装置3包括图24-26的图7-11的雾化组件2，采用上方进液的方式；图27-29的实施例中，雾化装置3包括图16-19的雾化组件2，采用横向两端进液的方式。
该雾化由于采用上述的雾化组件2，导液体21设置在雾化雾化单元1容纳仓13内，被支架12、发热体11、盖体124从四周限制压紧，起到传导液体21的作用；发热体11的拱起一侧和气流流动更加匹配，可以使得雾化面的热量更加均匀；支架12为发热体11提供支撑强度，使发热体11不易变形，同时与发热体11界定出容纳导液体21的容纳仓13，并将导液体21压缩紧使导液材料和发热体11直接接触良好；由于发热部111不再是周向覆盖的，所以可以根据要求采用不同的进液方式，将进液孔12d设在不同位置，例如可以设在发热体11的第二方向b上的两端；也可以设在发热体11的内凹一侧对着的位置；发热体11不再是通过人工在导液体21外周缠绕电加热丝制成，而可以通过模内注塑工艺，发热体11和支架12通过模内注塑成型，固定部113嵌入到支架12内部，可以方便后续的组装过程中实现自动化生产。
当该雾化装置3为电子烟时，雾化装置3的储液仓313中存储烟液，导液体21将烟液传导到加热体进行加热雾化。
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。
