 本发明的实施方式
为使本发明的目的、技术方案和优点更加清楚明白，下面结合实施例和附图，对本发明做进一步的详细说明，本发明的示意性实施方式及其说明仅用于解释本发明，并不作为对本发明的限定。
图1至图2示出了本发明第一实施例的基体，该基体1可应用于雾化芯中，用于吸取雾化液并提供给发热体2从而对雾化液进行加热雾化。其中，基体1包括导液面以及雾化面，基体1上设有至少两个导液孔13以及至少一个储液孔道14。
基体1的导液面及雾化面分别位于基体相对的第一面及第二面，其中，基体1的第一面与第二面中的其中一者可为导液面，用于与雾化液对应；另一者为雾化面，用于将雾化液供给发热体2从而进行加热雾化。
如图1至图2所示，该至少两个导液孔13从基体1的导液面贯穿至雾化面，将基体1的导液面与雾化面连通，用于将导液面上的雾化液吸取、传递至雾化面。其中，基体1可大致呈但不限于长方体状，其导液面与雾化面相互平行设置。在一些实施例中，基体1可呈其它形状设置，其导液面与雾化面相互平行设置，例如基体1呈圆柱状、椭圆柱状等规则或不规则的形状设置。在一些实施例中，基体1可呈其它形状设置，其导液面与雾化面成其它角度关系设置，例如基体1呈不规则形状设置。
该至少两个导液孔13相互平行设置，使得各个导液孔13将雾化液从导液面传导至雾化面的路径相同。可以理解地，该至少两个导液孔13基本平行设置也是较佳的。
该至少两个导液孔13垂直导液面设置，使得导液孔13从导液面吸取雾化液的路径较短。在一些实施例中，该至少两个导液孔13垂直雾化面设置，使得导液孔13将雾化液传导至雾化面的路径较短。在一些实施例中，该至少两个导液孔13同时垂直导液面及雾化面设置，使得雾化液在基体1中的移动均与导液面及雾化面相垂直，使得雾化液的传导距离及传导时间短，有效提高雾化效率。在一些实施例中，该至少两个导液孔13与导液面及雾化面呈其它夹角设置，可以理解地，导液孔13基本垂直于导液面及雾化面设置也是较佳的。
该至少两个导液孔13均匀相隔地分布于基体1上，如图1所示，该至少两个导液孔13在导液面及雾化面的长度方向以及宽度方向上均匀相隔地布置，使得传导至雾化面上的雾化液均匀分布，进而雾化均匀。在本实施例中，各导液孔13在导液面及雾化面的长度方向以及宽度方向上并排设置，并且，相邻导液孔13在长度方向上的间隔与在宽度上的间隔相等，使得供液均匀。
如图2所示，该至少两个导液孔13中，任一导液孔13各处的径向尺寸均相等，其中，导液孔13可呈但不限于圆筒状。进一步地，该至少两个导液孔13中各导液孔13的形状、径向尺寸均一致，使得各导液孔13传导至雾化面上的雾化液的量相等，导液均匀。在一些实施例中，任一导液孔13可呈椭圆柱状等规则或不规则的形状设置；在其它一些实施例中，该至少两个导液孔13中各导液孔13的形状、径向尺寸相同或不同，但各导液孔13可容纳雾化液的容积相同。
在本实施例中，该至少两个导液孔13通过该至少一个储液孔道14相互连通，如图所示，该至少一个储液孔道14中，各储液孔道14设置于相邻的导液孔13之间，用于连通相邻的导液孔13。
其中，相邻的导液孔13之间设有一个储液孔道14，并该储液孔道14与导液孔13的中部连通。在一些实施例中，储液孔道14可与导液孔13的上部或下部连通。可以理解地，导液孔13通过储液孔道14相互连通，使得基体1内各导液孔13中雾化液的液面高度保持一致，保证了对雾化面12的供液均匀，雾化效果好；同时，储液孔道14给雾化液提供更多的存储空间，从而增强基体1的储油功能，进而提高雾化的稳定性。
其中，该至少一个储液孔道14中，任一储液孔道14的各处的径向尺寸均相等，其中，储液孔道14可呈但不限于圆筒状。进一步地，当储液孔道14设有至少两个时，各储液孔道14的形状、径向尺寸均一致，使得各储液孔道14的储液能力相同。在一些实施例中，任一储液孔道14可呈椭圆柱状等规则或不规则的形状设置；在其它一些实施例中，该至少一个储液孔道14中各储液孔道14的形状、径向尺寸相同或不同，但各储液孔道14可容纳雾化液的容积相同。
进一步地，该至少一个储液孔道14中，各储液孔道14垂直导液孔13设置。具体地，储液孔道14与导液面11、雾化面12平行设置，并与导液孔13垂直设置，储液能力好。在一些实施例中，储液孔道14可与导液孔13成其它角度关系设置，可以理解地，储液孔道14基本垂直导液孔13设置也是较佳的。
图3至图4示出了本发明第二实施例的基体，该实施例的基体1与上述第一实施例的基体1的区别在于，相邻的导液孔13之间设置的储液孔道14的数量不同，其中，相邻的导液孔13之间设有至少两个储液孔道14，该至少两个储液孔道14沿基体1的导液面与雾化面之间均匀相隔地分布，其中，该至少两个储液孔道14可相互平行设置。
如图3所示，在本实施例中，相邻的导液孔13之间设有两个储液孔道14，该两个储液孔道14分别与导液孔13的上部、下部连通，并且间隔均匀地分布于基体1的导液面与雾化面之间。该两个储液孔道14平行设置，皆垂直导液孔13设置。
如图4所示，该实施例的基体1作为图3所示实施例的基体1的替代方案，该实施例的基体1与上述实施例的基体1的区别在于，相邻导液孔13之间设有三个储液孔道14，该三个储液孔道14分别与导液孔13的上部、中部、下部连通，并且间隔均匀地分布于基体1的导液面与雾化面之间，通过设置更多的储液孔道14，可进一步增强基体1的储液能力。在一些实施例中，相邻导液孔13之间可设置4个、5个、6个或更多个储液孔道14。
其中，各实施例中，同一基体1上的储液孔道14的形状、径向尺寸与导液孔13的形状、径向尺寸可相同或不同。
图5至图6示出了本发明第三实施例的基体1，该实施例的基体1与上述第一实施例的基体1的区别在于，基体1上还设有至少一个延长孔道15，该至少一个延长孔道15与导液孔13连通并背离储液孔道14延伸设置，以提供更多的储液空间。
如图5所示，在本实施例中，延长孔道15与导液孔13连通，其中，延长孔道15可以与储液孔道14对应，延长孔道15与导液孔13的中部连通。
当该至少一个延长孔道15包括多个时，该多个延长孔道15可分布于各导液孔13上，其中，每一导液孔13上连通的储液孔道14与延长孔道15数量之和相等。如图6所示，当基体1上的导液孔13设有多个时，位于拐角上的四个导液孔13中，每一导液孔13可连通有两个延长孔道15以及两个储液孔道14，其它导液孔13可连通有三个储液孔道14以及一个延长孔道15。
导液孔13上的延长孔道15背离储液孔道14延伸设置，在一些实施例中，延长孔道15与储液孔道14均匀间隔地周向连通在导液孔13上，使得储液均匀。
其中，延长孔道15垂直导液孔13设置。具体地，延长孔道15与导液面、雾化面平行设置，并与导液孔13垂直设置，储液能力好。在其它一些实施例中，延长孔道15可与导液孔13呈其它角度关系设置，可以理解地，延长孔道15基本垂直导液孔13设置也是较佳的。
图7示出了本发明第四实施例的基体1，该实施例的基体1与上述第二实施例的基体1的区别在于，基体1上还设有至少一个延长孔道15，该至少一个延长孔道15与导液孔13连通并背离储液孔道14延伸设置。

其中，各导液孔13中，延长孔道15与储液孔道14的数量之和相等。在相邻导液孔13之间设有三个储液孔道14，该三个储液孔道14分别与导液孔13的上部、中部、下部连通的实施例中，延长孔道15与储液孔道14对应，延长孔道15与导液孔13的上部、中部、下部连通。当基体1上的导液孔13设有多个时，位于拐角上的四个导液孔13中，每一导液孔13上可连通有六个延长孔道15以及六个储液孔道14，其它导液孔13可连通有九个储液孔道14以及三个延长孔道15。位于上部、中部、下部上的延长孔道15并列设置，位于上部、中部、下部上的储液孔道14并列设置。
其中，各实施例中，同一基体1上的延长孔道15的形状、径向尺寸与储液孔道14的形状、径向尺寸可相同或不同。
图8示出了本发明第五实施例的基体1，该实施例的基体1与上述第一实施例的基体1的区别在于，基体1上导液孔13的形状不同。具体地，导液孔13两端的径向尺寸均大于其中部的径向尺寸，也即同一导液孔13中，其位于基体1内部部分的径向尺寸大于其位于基体1表面部分的径向尺寸，使得增大雾化液的存储空间的同时利于锁液、防止漏液。
如图8所示，导液孔13的径向尺寸由两端向中部方向逐渐增大，导液孔13可呈圆滑过渡，导液孔13的开孔呈圆形设置。在一些实施例中，导液孔13的径向尺寸也可呈其它形式变化，可以为导液孔13的径向尺寸由两端向中部方向呈阶梯式逐渐增大。在一些实施例中，导液孔13的开孔可呈椭圆、矩形等规则或不规则的形状设置。
    图9示出了本发明第六实施例的基体1，该实施例的基体1与上述第二实施例的基体1的区别在于，基体1上导液孔13的形状不同。其中，该实施例中的导液孔13与上述第五实施例中的导液孔13相同。
    可以理解地，在相邻导液孔13之间设有三个储液孔道14，该三个储液孔道14分别与导液孔13的上部、中部、下部连通的实施例中，导液孔13的形状也可与上述第五实施例中的导液孔13相同。
图10示出了本发明第七实施例的基体1，该实施例的基体1与上述第三实施例的基体1的区别在于，基体1上导液孔13的形状不同。其中，该实施例中的导液孔13与上述第五实施例中的导液孔13相同。
图11示出了本发明第八实施例的基体1，该实施例的基体1与上述第四实施例的基体1的区别在于，基体1上导液孔13的形状不同。其中，该实施例中的导液孔13与上述第五实施例中的导液孔13相同。
在相邻导液孔13之间设有三个储液孔道14，该三个储液孔道14分别与导液孔13的上部、中部、下部连通的实施例中，导液孔13的形状也可与上述第五实施例中的导液孔13相同。
上述各实施例的基体1中，基体1可以为通过流延成型工艺形成若干流延生带，分别对该若干流延生带进行打孔，再将打孔后的流延生带通过多层叠压形成的陶瓷基体。具体地，在制备该基体1时，首先把粉碎好的粉料与有机塑化剂溶液按适当配比混合制成具有一定黏度的料浆，料浆从容器同流下，被刮刀以一定厚度刮压涂敷在专用基带上，经干燥、固化后从上剥下成为流延生带，其中，该一定厚度可为10um-1000um。
形成若干流延生带后，根据对导液孔13、储液孔道14、延长孔道15的孔径要求以及孔隙率要求，分别在各流延生带上进行打孔，再将打孔后的该若干流延生带通过层叠的方式形成一个完整的具有相应孔、相应孔道的生坯，通过烧结最终得到陶瓷基体。
其中，可通过激光打孔、或机械打孔的方式对流延生带进行打孔。可以理解地，可根据相应孔、相应孔道的孔径、以及孔隙率需求，分别对各流延生带打孔，最终形成完整的孔、孔道。该打孔方式简单易行，可达到目标孔径以及孔隙率，易于实现小孔径，且便于实现各导液孔13的均匀布置。
在一些实施例中，基体1可以为通过3D打印工艺形成的陶瓷基体。具体地，可根据导液孔13、储液孔道14、延长孔道15的孔径要求以及孔隙率要求设置3D打印的工艺参数，打印得到生坯，并通过烧结最终得到陶瓷基体。可以理解地，该打印方式便于孔径以及孔隙率的调控，易于实现小孔径，且便于实现各导液孔13的均匀布置。
在其它一些实施例中，基体1可由玻璃陶瓷、玻璃等硬质毛细结构制成。
图12至图13示出了本发明的雾化芯，该雾化芯包括基体1以及发热体2，其中，基体1可采用上述任一实施例中的基体1实现，发热体2设置于基体1的雾化面12上，以下以雾化芯采用上述第八实施例的基体1为例进行说明。
图12示出了本发明第一实施例的雾化芯，如图12所示，基体1的雾化面12可位于基体1的顶面，发热体2设置于基体1的顶面上，可以理解地，由于毛细管力的作用，由导液面11吸取雾化液，并通过导液孔13上升移动并传递至雾化面12，从而发热体2对雾化液进行加热雾化。
其中，发热体2设置于基体1的顶面上，基体1上的导液孔13均匀间隔围绕发热体2分布。其中，发热体2可覆盖雾化面12上导液孔13的开口，从而对传递至雾化面12的雾化液充分雾化。具体地，发热体2的长度与雾化面12长度方向上两端上的导液孔13之间的长度相比，前者与后者相等，或者，前者大于后者；发热体2的宽度与雾化面12宽度方向上两端上的导液孔13之间的长度相比，前者与后者相等，或者，前者大于后者。
图13示出了本发明第二实施例的雾化芯，如图13所示，该实施例的雾化芯与上述第一实施例的雾化芯的区别在于，基体1的雾化面12位于基体1的底面，发热体2设置于基体1的底面上，基体1上的导液孔13均匀间隔围绕发热体2分布。可以理解地，由于毛细管力的作用，由导液面11吸取雾化液，并通过导液孔13下降移动并传递至雾化面12，从而发热体2对雾化液进行加热雾化。其中，发热体2的设置形式与上述第一实施例中雾化芯的发热体2的设置形式相同。
上述各实施例的雾化芯中，发热体2可通过烧结的方式与基体1一体成型。具体地，当发热体2为金属薄片时，将发热体2埋入基体1的生坯中，通过烧结即可。当发热体2呈镀膜式时，可以先将发热体2镀在一个有机膜片上，然后将该带有发热体2的有机膜片插入生坯中，再通过烧结，可以理解地，该有机膜片在烧结过程中会被烧掉，只留镀膜式的发热体2与基体1紧密地结合在一起。
在一些实施例中，发热体2可以为发热丝或发热片，并嵌设于基体1上。具体地，基体1上与其雾化面12相应的一面上设有容置槽，发热体2紧密地容置于该容置槽中，实现发热体2的嵌入。其中，发热体2容置于容置槽中时，发热体2的顶面与雾化面12齐平或低于雾化面12。可以理解地，当发热体2的顶面与雾化面12平齐时，发热体2的顶面露出在外，可以更快速地将顶面附近的雾化液雾化，具有雾化快、方便安装的优点；当发热体2的顶面低于雾化面12时，使顶面不暴露，从而降低出现干烧的情况。其中，发热体2可由不锈钢、镍铬合金、铁铬铝合金、金属钛等制成。
在一些实施例中，发热体2可以为发热膜。在一些实施例中，发热膜可以通过丝网印刷工艺涂覆在基体1上，可以理解地，将基体11作为承印物，通过丝网印刷工艺，将发热膜涂覆在基体1上。在一些实施例中，发热膜可以通过真空镀膜工艺在基体1上形成，具体地，在真空的条件下加热金属材料，使其蒸发并凝结于基体1的雾化面12表面，从而形成发热膜。
本发明还提供一种雾化组件，该雾化组件包括下座体、设置于该下座体上的上座体以及夹持于该上座体与该下座体之间的雾化芯，其中，该雾化芯可以采用上述各实施例中的雾化芯。
本发明还提供一种雾化器，该雾化器包括上述雾化组件以及与该雾化组件相配合的储液装置，储液装置包括储液腔，雾化芯的基体1的导液面11与储液腔相连通，基体1的雾化面12背离储液腔，并雾化面12与下座体之间形成雾化腔。
其中，储液腔内可存储有雾化液，基体1通过其导液面11从储液腔中吸取雾化液，并通过其导液孔13将雾化液自导液面11传导至雾化面12，雾化面12上的发热体2对其附近的雾化液进行加热雾化，生成气溶胶基质并充盈在雾化腔中，供用户抽吸。可以理解地，发热体2从基体1上获得的雾化液稳定，且雾化均匀，用户体验感好。
本发明还提供一种电子雾化装置，该电子雾化装置包括上述的雾化器以及用于给雾化器供电的电源组件，其中，下座体上可以设有与发热体2电性连接的电极柱，该电极柱与电源组件的正负极连接，给发热体2供电。
可以理解的，以上实施例仅表达了本发明的优选实施方式，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，可以对上述技术特点进行自由组合，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，凡跟本发明权利要求范围所做的等同变换与修饰，均应属于本发明权利要求的涵盖范围。
