 有益效果
实施本发明具有以下有益效果：本发明的雾化组件，通过在陶瓷雾化芯与支架之间填充用于密封该间隙的柔性导液体，由于柔性导液体具有一定的弹性，可以填充陶瓷雾化芯与支架的间隙；同时柔性导液体浸润雾化烟油后，雾化烟油填充柔性导液体内部间隙，这时候柔性导液体相当于一层油膜，可以起到很好的密封作用，进而避免漏液现象的出现，也避免糊芯的问题的出现；同时，陶瓷雾化芯内的空气可以通过陶瓷导液体上的换气微槽穿过柔性导液体进入到储油仓内，这样可不占用陶瓷导液体的微孔通道就可以形成换气通道，进而平衡储油仓内外气压，达到更加顺畅供液的效果。

图1-图5示出了本发明一些优选实施例中的一种雾化组件5，包括中空结构的支架1、设置于支架1内的陶瓷雾化芯2，支架1与陶瓷雾化芯2之间的间隙填充有用于密封该间隙的柔性导液体3。支架1的作用在于提供支撑强度，支架1为中空结构，陶瓷雾化芯2安装在支架1内，支架1侧壁上设有用于向柔性导液体3导液的进液口11，控制进液口11的大小可以控制雾化烟油与柔性导液体3的接触面积，进而控制导液速率。柔性导液体3指的是具有可以供给液体通过的多孔材料，而且是柔性的材料，可以是具备一定弹性的导液棉、导液布、导液棉块或者导液棉管，柔性导液体3作用是填充支架1和陶瓷雾化芯2之间的间隙，同时柔性导液体3浸润雾化烟油后，雾化烟油填充柔性导液体3内微孔间隙，这时候柔性导液体3相当于一层油膜，可以起到很好的密封作用。
如图2所示，陶瓷雾化芯2包括陶瓷导液体21和发热体22，陶瓷导液体21与柔性导液体3相贴合的表面形成进液面211，陶瓷导液体21与发热体22相贴合或相嵌接的表面形成雾化面212，陶瓷导液体21对应雾化面212沿轴向方向上下贯通以形成气流通道B；雾化烟油由支架1的进液口11进入，传导至柔性导液体3，通过柔性导液体3经进液面211传导进入陶瓷导液体21内，陶瓷导液体21作用是提供微孔通道传导雾化烟油，雾化烟油进入至雾化面212，被雾化面212上的发热体22加热雾化，雾化形成雾化蒸汽，与空气混合形成气溶胶，经由气流通道B向上排出。
在一些优选实施例中，如图2、图4所示，陶瓷导液体21对应于进液面211上开设有至少一个与进液口11相连通的换气微槽214，使雾化面212、换气微槽214、柔性导液体3以及进液口11、储油仓相连通形成换气通道A。储油仓内随着雾化烟油的消耗，储油仓内的雾化烟油减少，气压减小，储油仓外界空气要进入储油仓，由于储油仓周围都是密封环境，气体只能通过陶瓷导液体21的多孔结构经过支架1的进液口11进入，这就会导致陶瓷导液体21的部分微孔通道内存在空气，导致部分陶瓷导液体21内出现无雾化烟油的情况，如果此时发热体22还在工作，将导致没有雾化烟油到雾化面212，发热体22位置没有雾化烟油被加热汽化，而发热体22是通过雾化、汽化雾化烟油消耗能量而降温的，发热体22无法雾化将会导致干烧，产生一些糊味以及释放甲醛等醛类有害物质。而在本发明中，当用于储存雾化烟油的储油仓的雾化烟油被消耗后，储油仓内空间变大，气压变小，这时候外界空气要进入储油仓，陶瓷雾化芯2内的空气可以通过陶瓷导液体21上的换气微槽214穿过柔性导液体3进入到储油仓内，这样可不占用陶瓷导液体21的微孔通道就可以形成换气通道A，进而平衡储油仓内外气压，达到更加顺畅供液的效果。
在一些具体的实施例中，如图2、图4-图8所示，换气微槽214为由陶瓷导液体21的进液面211的底部向上延伸设置的微槽，且至少延伸至对应进液口11位置，也就是说，进液口11对应至柔性导液体3上的投影与换气微槽214对应至柔性导液体3上的投影至少部分重叠，使得气流通道B上的空气可沿换气微槽214的延伸方向向上流通，并经柔性导液体3上的间隙流通至进液口11，进入储油仓，达到换气的效果，保证陶瓷导液体21内的微孔内持续存在雾化烟油，达到顺畅的供液效果。
在一些具体的实施例中，换气微槽214的槽深为0.2-2mm；由于陶瓷导液体21本身的多孔结构，该孔的孔径一般在几微米到几十微米，基本属于不可见的通孔，而本发明在陶瓷导液体21的表面开设的换气微槽214的槽深为0.2-2mm，为可见槽，相比陶瓷导液体21内部的微孔较大，陶瓷导液体21内的毛细通道较细，陶瓷导液体21表面的换气微槽214形成的毛细通道较粗，陶瓷导液体21内的毛细通道的毛细力大于换气微槽214的毛细力，因此雾化液烟油易被陶瓷导液体21内的毛细力锁住，而气体冲破换气微槽214的处雾化烟油的力要小于陶瓷导液体21内微孔通道的力，因此相当于换气微槽214处的油膜更容易被气体冲破而使气体顺利进入储油仓。
在一具体的实施例中，如图1-3所示，陶瓷导液体21呈圆筒状结构，对应的柔性导液体3、支架1也呈圆筒状结构，发热体22为螺旋筒状或圆柱状，使得支架1、柔性导液体3、陶瓷导液体21、发热体22相互匹配，安装时也更方便、快捷；也使得陶瓷导液体21能均匀的分布在圆筒状的柔性导液体3内，可以使得由支架1的进液口11至柔性导液体3、陶瓷导液体21之间的导液更顺畅。
在一具体的实施例中，如图3所示，进液口11沿支架1的周向间隔设置，雾化烟油可以从周向设置的进液口11入，柔性导液体3可以快速导液至陶瓷导液体21，使得雾化组件5内360度均能导液，极大的提高了导液速度，使得形成的雾化蒸汽更加浓郁饱和；且在高功率的情况下，耗液量必然会增加，而环绕式的进液口11使雾化烟油导液速度加快，使得雾化组件5能更好的持续工作而不易烧糊。与此同时，陶瓷导液体21沿外壁面周向间隔设置有与进液口11相连通的换气微槽214，进液口11与换气微槽214的对应关系可为一一对应，或一对多，或多对应，以使雾化面212与进液口11相连通，进而使得气流通道B的气体更好的冲破换气微槽214处的油膜，经进液口11进入储油仓。
在一具体的实施例中，如图5-图9所示，陶瓷导液体21呈上下贯通的方柱结构，对应的，支架1也呈上下贯通的方柱结构，柔性导液体3为与陶瓷导液体21对应的方柱结构、半包围结构或方块结构，以填充于支架1与陶瓷导液体21之间，发热体22为片状结构或上下贯通的方柱结构，使得支架1、柔性导液体3、陶瓷导液体21、发热体22相互匹配，安装时也更方便、快捷。这里的半包围结构指的是方柱结构的支架1上并非所有侧面均设有进液口11，此时在对应进液口11的侧面设置有柔性导液体3，没有设置有进液口11的支架1的侧面并未设置柔性导液体3，所有柔性导液体3连接成为一体的半包围结构，或者，柔性导液体3为与支架1相匹配的方柱结构，柔性导液体3套设于支架1内；或者柔性导液体3为单独的方块结构，每个柔性导液体3对应开设进液口11的支架1的侧面设置，以填充支架1与陶瓷导液体21之间的间隙；当发热体22为片状结构时，片状结构的发热体22贴附或嵌接于陶瓷导液体21内部，对应至陶瓷导液体21上形成的雾化面212只有一侧面；当发热体22为上下贯通的方柱结构，上下贯通的方柱结构的发热体22贴附或嵌接于陶瓷导液体21内部，对应至陶瓷导液体21上形成的雾化面212具有多个，雾化气体更浓郁。
在一具体的实施例中，如图5-9所示，发热体22为片状结构，陶瓷导液体21与发热体22相贴附或相嵌接的表面为雾化面212，在与雾化面212相对的进液面211设置有换气微槽214，和/或在与雾化面212相背的进液面211上设置有换气微槽214，换气微槽214将雾化面212与进液口11相连通；片状结构的发热体22所在的面是发热面，也就是雾化面212，这里的相对的进液面211，指的是与该发热面直接对应的进液面211，也就是距离该发热面距离最近的进液面211；这里的相背的进液面211指的是，与该发热面距离最近的进液面211相对称的一进液面211，也就是与雾化面212相对侧方向上的进液面211；可以理解的，换气微槽214可以只设置于与雾化面212对应的一侧进液面211上，也可以只设置于与雾化面212相背的对侧进液面211上，也可以同时设置于所有的进液面211上，雾化组件5可以利用同侧方向上的换气微槽214进行换气，也可以利用对侧方向上的换气微槽214进行换气。
在一具体的实施例中，如图1所示，发热体22包括发热线路221和与发热线路221两侧延伸的电极引线222，电极引线222连接电极，电极给发热线路221供电使其发热，从而雾化与发热线路221接触的陶瓷导液体21上的雾化烟油；具体的，发热线路221呈螺旋状结构、管状结构、呈柱状结构、呈片状结构或呈膜状结构，发热线路221的形状根据与之配合的陶瓷导液体21内部形状设置，具体不做限制，使得两者相互嵌接或贴合即可，使得雾化面212可以是圆柱面、平面或者弧形面等。
在一具体的实施例中，柔性导液体3用于填充密封支架1和陶瓷雾化芯2之间的间隙，其根据支架1以及陶瓷雾化芯2的形状设置，具体可以是多层导液布重叠卷成的筒状结构、管装结构，或多层导液布重叠的块状结构，使得柔性导液体3将两者之间的间隙密封即可，导液布可采用如亚麻纤维棉、芳纶纤维棉等材料制成，具有耐高温以及具有多孔导液功能。
本发明还提供一种雾化装置，如图10-图11所示，包括外壳4、设置于外壳4内的雾化组件5、密封座6、设置于密封座6底部且与外壳4连接的底座7，雾化组件5、外壳4和密封座6之间形成密闭的储油仓10，雾化组件5的支架1的进液口11与储油仓10相连通；底座7上设有容置位，密封座6容置于底座7的容置位上，底座7设置于外壳4底座7开口端，并与外壳4内壁紧密接触，在底座7上开设有进气口72，进气口72用于使外部空气进入到雾化组件5内，底座7上还开设有电极穿插孔71，电极9通过电极穿插孔71与发热体22实现电连接。当储油仓10内存在满雾化烟油的情况时，柔性导液体3密封填充支架1与陶瓷导液体21之间的间隙，雾化组件5内的陶瓷导液体21会由于本身的多孔结构毛细现象吸收满雾化液，而当雾化装置的电极9两端供电时，陶瓷导液体21内的发热体22工作，产生热量，热量将雾化烟油加热至沸点蒸发成蒸汽，和空气混合形成气溶胶，最终被吸食。
进一步地，优选雾化装置还包括导气管8，支架1向上延伸有导气筒12，导气筒12卡设于导气管8内，使得导气管8与雾化组件5相连通，雾化组件5产生的气溶胶经由雾化组件5、导气筒12以及导气管8流出雾化装置外。
雾化装置的其他结构可以采用现有技术，在此不再赘述。
