请一并参阅图1至图3，现对本实用新型实施例提供的雾化组件1进行说明。本实用新型实施例提供的雾化组件适用于气溶胶发生装置的雾化器，雾化器通过该雾化组件将气溶胶形成基质雾化形成烟雾，以供用户吸食而达到模拟吸烟的效果。本实用新型实施例提供的雾化组件包括第一多孔基体1、第二多孔基体2和中间加热元件3，第一多孔基体1和第二多孔基体2均呈板片状结构设置，第一多孔基体1和第二多孔基体2的形状可以是但不限于圆形、椭圆形、矩形、菱形、梯形或异型等形状，第一多孔基体1和第二多孔基体2的形状与大小，可以根据实际使用需要而合理选取设置，在此不作唯一限定。请结合参阅图4，第一多孔基体1内部具有第一微孔结构11，第一微孔结构11可以将雾化器之储液件中的气溶胶形成基质吸附并存储于第一多孔基体1内部，且由存储于第一多孔基体1内部的气溶胶形成基质雾化形成的烟雾，可通过第一微孔结构11传输至第一多孔基体1的至少部分外表面，并从第一多孔基体1的至少部分外表面流出，且第一多孔基体1的至少部分外表面形成第一雾化面12。也就是说，第一多孔基体1的至少部分外表面包括第一多孔基体1的第一雾化面12(第一多孔基体1背离中间加热元件3的一面)和第一多孔基体1的其他侧面，烟雾可以由第一多孔基体1的第一雾化面12流出，烟雾也可以第一多孔基体1的其他侧面流出。第二多孔基体2内部具有第二微孔结构21，第二微孔结构21可以将雾化器之储液件中的气溶胶形成基质吸附并存储于第二多孔基体2内部，且由存储于第二多孔基体2内部的气溶胶形成基质雾化形成的 烟雾，可通过第二微孔结构21传输至第二多孔基体2的至少部分外表面，并从第二多孔基体2的至少部分外表面流出，且第二多孔基体2的至少部分外表面形成第二雾化面22。也就是说，第二多孔基体2的至少部分外表面包括第二多孔基体2的第二雾化面22(第二多孔基体2背离中间加热元件3的一面)和第二多孔基体2的其他侧面。烟雾可以由第二多孔基体2的第二雾化面22流出，烟雾也可以第二多孔基体2的其他侧面流出。请结合参阅图1，中间加热元件3夹设于第一多孔基体1与第二多孔基体2之间，中间加热元件3在通电后产生热量，对吸附存储于第一多孔基体1与第二多孔基体2内部的气溶胶形成基质进行加热，以形成供用户模拟吸烟使用的烟雾。
本实用新型实施例提供的雾化组件在使用时，利用第一微孔结构11将气溶胶形成基质吸附并存储于第一多孔基体1内部，利用第二微孔结构21将气溶胶形成基质吸附并存储于第二多孔基体2内部，位于第一多孔基体1与第二多孔基体2之间的中间加热元件3，在通电后产生热量，便可对吸附存储于第一多孔基体1与第二多孔基体2内部的气溶胶形成基质进行加热，以使气溶胶形成基质雾化形成供用户模拟吸烟使用的烟雾。这样，利用第一微孔结构11和第二微孔结构21吸附和存储气溶胶形成基质，气溶胶形成基质可分别均匀地分散于第一多孔基体1与第二多孔基体2内部，并且加热层产生的热量从中间分别向位于其两侧的第一多孔基体1与第二多孔基体2进行加热，同时位于第一多孔基体1与第二多孔基体2之间的中间加热元件3，可将热量均匀地传递至第一多孔基体1与第二多孔基体2，使得气溶胶形成基质均匀受热，改善了气溶胶形成基质受热不均的问题。此外，将中间加热元件3夹设于分别吸附并存储有气溶胶形成基质的第一多孔基体1与第二多孔基体2之间，无需在中间加热元件3上包覆吸液棉，有效克服具有包棉雾化芯结构存在的加热雾化一致性差而导致干烧、碳化的问题，进而可延长雾化芯的使用寿命及提升雾化口感，安全性高。
本实用新型实施例提供的雾化组件，与现有技术相比，通过将中间加热元 件3夹设于内部具有第一微孔结构11的第一多孔基体1与内部具有第二微孔结构21的第二多孔基体2之间，整体结构一致性良好。则在使用时，仅需利用第一微孔结构11和第二微孔结构21吸附和存储气溶胶形成基质，便可使得气溶胶形成基质分别均匀地分散于第一多孔基体1与第二多孔基体2内部。这样，中间加热元件3在通电后产生的热量，经位于第一多孔基体1与第二多孔基体2之间的中间陶瓷基体31，均匀地传递至第一多孔基体1与第二多孔基体2，从而使得气溶胶形成基质均匀受热，改善了包棉雾化芯结构存在的气溶胶形成基质受热不均的问题。此外，将中间加热元件3夹设于分别吸附并存储有气溶胶形成基质的第一多孔基体1与第二多孔基体2之间，无需在中间加热元件3上包覆吸液棉，有效克服包棉雾化芯结构容易引发干烧、碳化的问题。
请结合参阅图1、图2和图3，在其中一些实施例中，中间加热元件3包括夹设于第一多孔基体1与第二多孔基体2之间的中间陶瓷基体31，以及设于中间陶瓷基体31上和/或中间陶瓷基体31中的发热件32。具体地，请结合参阅图1和图2，设有发热件32的中间陶瓷基体31，采用平面固定结合的方式夹设于第一多孔基体1与第二多孔基体2之间。其中，平面固定结合的方式包括但不限于烧结或平面粘合的方式，加热层设置有至少2根引线，引线用于电路的导通，至少2根引线引线可以是设置在加热层同侧，也可以分别设置在加热层的不同侧。发热件32用于在通电后产生热量，对吸附存储于第一多孔基体1与第二多孔基体2内部的气溶胶形成基质进行加热，以形成供用户模拟吸烟使用的烟雾。可以理解地，在其中一些实施例中，第一多孔基体1、第二多孔基体2与中间陶瓷基体31的形状与大小可以一致，第一多孔基体1、第二多孔基体2与中间陶瓷基体31的形状与大小也可以不一致。当第一多孔基体1、第二多孔基体2与中间陶瓷基体31的形状与大小一致时，有利于进一步增强雾化组件整体结构的一致性。在其中一些实施例中，第一多孔基体1可以是但不限于多孔陶瓷，第二多孔基体1可以是但不限于多孔陶瓷。
请结合参阅图1、图2和图3，在其中一些实施例中，中间加热元件3包括夹设于第一多孔基体1与第二多孔基体2之间的生瓷带，以及设于生瓷带上的发热件，发热件为印刷或喷涂于生瓷带表面的金属发热线路。这样，在发热件32设于中间陶瓷基体31上时，中间陶瓷基体31为生瓷带，发热件32为设于生瓷带表面的金属发热线路。该实施例中，通过采用上述方案，中间陶瓷基体31采用生瓷带，并在生瓷带表面设置金属发热线路，金属发热线路在生瓷带表面形成通电后发热的发热件32。这样，设有金属发热线路的生瓷带便可构成中间加热元件3。具体地，金属发热线路可以采用包括但不限于印刷或喷涂的方式形成于生瓷带的表面。可以理解地，在其中一些实施例中，发热件32还可以为通过薄膜方式形成于生瓷带表面的金属薄膜，金属薄膜的厚度为1nm～100um。金属薄膜可以是但不限于铜、镍、珀、铝、金等金属薄膜，金属薄膜也可以是其他具备导电性金属氧化物、或者其它导电性材料薄膜。请结合参阅图1、图2和图3，在其中一些实施例中，生瓷带表面围绕金属发热线路环绕设置有陶瓷封装层311，在中间陶瓷基体31夹设于第一多孔基体1与第二多孔基体2之间时，陶瓷封装层311可将金属发热线路封装于雾化组件中，有效防止金属发热线路暴露而发生氧化，延长雾化组件的使用寿命。
请结合参阅图2和图3，在其中一些实施例中，金属发热线路呈C型结构或者S型结构排布于生瓷带的表面。该实施例中，通过采用上述方案，将金属发热线路呈回字型或者S型结构排布于生瓷带的表面，一方面可确保金属发热线路的发热有效面积更大，提高发热效率，另一方面可使得金属发热线路通电后产生的热量均匀分布，进而有利于气溶胶形成基质的均匀受热。可以理解地，金属发热线路可以是但不限于呈C型结构或者S型结构排布于生瓷带的表面，在其中另一些实施例中，金属发热线路也可以呈同心环状结构排布于生瓷带的表面，还可以呈同心圆弧状结构排布于生瓷带的表面。
请结合参阅图1、图2和图3，在其中一些实施例中，间加热元件3包括夹设于第一多孔基体1与第二多孔基体2之间的中间发热层，以及环绕中间发热 层的外周设置的陶瓷封装层。这样，在发热件设于中间陶瓷基体中时，发热件可以是设于第一多孔基体1与第二多孔基体2之间的中间发热层，中间发热层的外周环绕设置有陶瓷封装层311，陶瓷封装层311为致密的陶瓷层。雾化组件制作时，先在第一多孔基体1(或第二多孔基体2)的一侧印刷或放置蚀刻金属发热材料以形成中间发热层，接着在金属发热材料周围再用致密的陶瓷层填充，最后在金属发热材料上覆盖第二多孔基体2(或第一多孔基体1)，以形成在中间发热层四周具有陶瓷封装层311的雾化组件。由于中间发热层周围填充有陶瓷封装层311，有效防止中间发热层的金属发热材料暴露而发生氧化，延长雾化组件的使用寿命。在其中一些实施例中，中间发热层的厚度为0.3～5mm。
请结合参阅图4，在其中一些实施例中，间加热元件3包括夹设于第一多孔基体1与第二多孔基体2之间的中间陶瓷基体或中间陶瓷层，以及设于中间陶瓷基体或中间陶瓷层中的发热件，发热件为嵌设于中间陶瓷基体或中间陶瓷层内部的金属发热材料或金属件。该实施例中，通过采用上述方案，中间陶瓷基体31呈片状结构设置，或者直接采用中间陶瓷层，并在中间陶瓷基体31或中间陶瓷层内部嵌设金属发热材料或金属件，内部嵌设有金属发热材料或金属件的中间陶瓷层构成中间陶瓷发热层。这样，中间陶瓷发热层便可构成中间加热元件3，中间陶瓷发热层在通电后可对第一多孔基体1与第二多孔基体2内部的气溶胶形成基质进行均匀加热。具体地，金属发热材料可以采用包括但不限于钨、钼、镍、铬、钼或锰中的一种或几种金属制作的发热片。当然，可以理解地，请结合参阅图5，在其中另一些实施例中，夹设于第一多孔基体1与第二多孔基体2之间的中间加热元件3，还可以是采用氮化铝、碳化硅、氧化铝陶瓷以及钨、钼、镍、铬、钼或锰中的一种或几种金属制作的陶瓷加热片。在其中另一些实施例中，夹设于第一多孔基体1与第二多孔基体2之间的中间加热元件3，还可以是采用将发热丝或加热棒等发热件嵌设于陶瓷材料内部的陶瓷发热器件。
可以理解地，在其中一些实施例中，中间陶瓷基体31呈片状结构设置，且 中间陶瓷基体31采用包括但不限于氮化铝、碳化硅、氧化铝等材料制成的陶瓷片，中间陶瓷基体31的厚度为0.3～5mm。当中间陶瓷基体31的厚度设置为0.3～1mm时，片状结构的中间陶瓷基体31的整体厚度较薄，使得中间加热元件3整体升温速度较快，加热效果更佳。中间陶瓷基体31的厚度为1～5mm时，有利于在中间陶瓷基体31中设置金属加热片。
可以理解地，在其中一些实施例中，第一多孔基体1和第二多孔基体2采用包括但不限于氧化铝、硅藻土、堇青石、莫来石、氧化锆、氧化硅等材料制成的陶瓷片，第一多孔基体1的厚度为0.1～5mm，第二多孔基体2的厚度为0.1～5mm，第一多孔基体1与第二多孔基体2的厚度可以相同也可以不同。第一微孔结构11的孔径范围控制在5～200μm之间，第二微孔结构21的孔径范围控制在为5～200μm之间，既保证第一微孔结构11、第二微孔结构21具有良好的储液能力，又可使得烟雾能够分别通过第一微孔结构11、第二微孔结构21传输至第一多孔基体1的第一雾化面12、第二多孔基体2的第二雾化面22。
本实用新型实施例还提供一种雾化器。本实用新型实施例提供的雾化器包括上述任一实施例提供的雾化组件。通过采用上述方案，由于该雾化器包括上述任一实施例中的雾化组件，可将该雾化器装配电源装置或气溶胶发生装置主机上使用，通过该雾化器将气溶胶形成基质雾化形成烟雾，以供用户吸食而达到模拟吸烟的效果。因本实用新型实施例提供的雾化器具有上述任一实施例中提供的雾化组件的全部技术特征，故其具有与上述雾化组件相同的技术效果。
本实用新型实施例还提供一种气溶胶发生装置，包括上述任一实施例提供的雾化组件或上述任一实施例提供的雾化器。由于气溶胶发生装置具有上述任一实施例中提供的雾化器或雾化组件的全部技术特征，故其具有与上述雾化器或雾化组件相同的技术效果。
