 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中的雾化组件，该雾化组件可包括用于从雾化器10的储液腔中吸取液态气溶胶生成基质的多孔基体1以及设置于多孔基体1上用于将吸附到多孔基体1中的液态气溶胶生成基质加热雾化的发热体2。
多孔基体1包括导液端12以及与导液端12相对设置的雾化端11，导液端12上设有导液面121，该导液面121用于与储液腔导液连通。雾化端11上设有用于安装发热体2的雾化面111。在本实施例中，多孔基体1呈长方体状，其导液端12的端面、雾化端11的端面呈长方形，且导液端12端面与雾化端11端面平行。在其它实施例中，多孔基体1的横截面也可以为方形、菱形、梯形、圆形、椭圆形等其他形状。
雾化组件还包括围栏结构3，该围栏结构3设置于雾化端11的端面上且围绕雾化面111设置，界定出一个收容槽5。在本实施例中，围栏结构3设置于雾化端11端面的周缘，雾化端11在围栏结构3内的区域形成雾化面111，围栏结构3呈封闭式设置，从而围栏结构3与雾化面111一道界定出一个收容槽5。可以理解地，该围栏结构3的设置，使得形成容积较大的收容槽5，从而可容纳较多的液态气溶胶生成基质。
如图2所示，围栏结构3垂直设置于雾化端11端面上，围栏结构3的外壁面与雾化端11端面的周缘相齐平；围栏结构3的上端面齐平设置且与雾化端11端面平行，以保证填充于收容槽5中各处的液态气溶胶生成基质较为均匀。围栏结构3可自雾化端11端面向外延伸形成，本实施例中，围栏结构3可通过一体成型的方式成型于雾化端11的端面上，且两者材质相同。
雾化面111设于雾化端11的端面上，雾化面111为平坦的表面，供发热体2设置于其上，在本实施例中，雾化端11的端面也可为平坦的表面，从而在雾化端11的端面形成表面平坦的雾化面111；导液端12的端面即为导液面121。在本实施例中，多孔基体1具有毛细结构，从而具有毛细作用力，发热体2呈多孔结构设置。
可以理解地，当启动外部电路正常雾化时，多孔基体1通过其毛细作用力，将其导液端12导液面121的液态气溶胶生成基质吸附至雾化端11的雾化面111上，并提供给发热体2，发热体2对流入其孔结构中的液态气溶胶生成基质进行加热雾化。同时，围栏结构3的设置，使得雾化端11雾化面111上的液态气溶胶生成基质可填充于收容槽5中，保证了雾化时液态气溶胶生成基质的充分供给以及供给均匀，有效防止发热体2出现局部温度过高的现象。
多孔基体1可为多孔陶瓷体；在其它实施例中，多孔基体1也可以为玻璃陶瓷、玻璃等硬质毛细结构，多孔基体1的毛细结构设置，保证了液态气溶胶生成基质的吸附。发热体2可为平铺于雾化面111上的平面型多孔发热膜，其可采用丝印、真空镀膜等方式成型于多孔基体1上，可以理解地，平面型多孔发热膜具有温度场分布均匀、能量利用率高等特点，利于雾化充分；在其它实施例中，发热体2也可以为具有多孔结构的发热片等发热部件，发热体2的多孔结构设置，液态气溶胶生成基质可在多孔结构中被加热雾化从而带走热量，可防止因收容槽5中液态气溶胶生成基质充足而导致发热体2温度过高而失效的情况发生。
平面型多孔发热膜的厚度可为10um至80um，多孔发热膜上孔的孔径可为10um至200um，多孔发热膜的孔隙率可为10%至70%。在本实施例中，平面型多孔发热膜的宽度可为0.5mm至3.0mm；在其它实施例中，平面型多孔发热膜的长度和宽度可根据雾化面111的尺寸进行选择设置。
如图2所示，围栏结构3的高度大于多孔发热膜的厚度，在本实施例中，围栏结构3的高度至少大于多孔发热膜的厚度10um至20um。使得液态气溶胶生成基质填充于收容槽5中时，可没过多孔发热膜，使得多孔发热膜的表层上均匀覆盖一层由液态气溶胶生成基质形成的油膜。可以理解地，多孔基体1通过其毛细作用力吸附液态气溶胶生成基质并提供给发热体2，覆盖发热体2的底层；从而通过该围堰的设置，使得多孔发热膜的表层以及底层均被液态气溶胶生成基质包围覆盖，保证了雾化时液态气溶胶生成基质的充分供给。
其中，围栏结构3可具有毛细结构，通过其毛细作用力使得液态气溶胶生成基质沿着围栏结构3逐渐填满整个收容槽5。在本实施例中，围栏结构3可为多孔陶瓷材质；在其它实施例中，围栏结构3可为玻璃陶瓷、玻璃等硬质毛细结构。
雾化组件还包括与多孔发热膜两端连接的电极部4，电极部4设置于收容槽5中由围栏结构3围绕，且电极部4的厚度大于围栏结构3的高度，该电极部4可与电源装置20电性连接，用于给多孔发热膜供电，多孔发热膜在电极部4通电下对液态气溶胶生成基质进行加热雾化；其中，两个电极部4可分别位于多孔发热膜长度方向的两端，多孔发热膜可以呈一字形设置，也可呈S型或其它形状设置；该电极部4可以为焊盘。
多孔发热膜、电极部4可均呈长方体设置，且电极部4的宽度大于多孔发热膜的宽度，两者呈阶梯形式设置，多孔发热膜与电极部4之间设有用于减少连接处温度梯度的连接段21。可以理解地，多孔发热膜中心向电极部4呈现缓慢降温趋势，该连接段21的设置可提高连接处抗冷热冲击性能。
该连接段21的横截面大致呈三角状设置，连接段21设置于多孔发热膜长度方向上的两侧，连接多孔发热膜与电极部4。其中，连接段21设有呈平滑过渡的斜面211，且该斜面211位于背向多孔发热膜的一侧，以减小多孔发热膜与电极部4之间的梯度。在本实施例中，该连接段21与多孔发热膜一体成型设置，且两者的材质相同。
图3至图4示出了本发明第二实施例中的雾化组件，该雾化组件与上述第一实施例的雾化组件的区别在于围栏结构3的设置位置不同，如图3至图4所示，在本实施例中，围栏结构3设置于多孔基体1的雾化端11端面上，且围栏结构3的外壁面与雾化端11端面的周缘之间具有间隔，雾化端11在围栏结构3内的区域形成雾化面111，从而围栏结构3与雾化面111一道界定出一个收容槽5。可以理解地，该围栏结构3的设置，，可较为紧密地围绕在发热体2的外周上，使得填充于收容槽5中的液态气溶胶生成基质可充分供给发热体2。
图5示出了本发明一些实施例中的电子雾化装置，如图5所示，该电子雾化装置大致可呈方形柱状并包括雾化器10以及与雾化器10电性连接的电源装置20。雾化器10可包括壳体101以及设置于壳体101中的雾化组件，壳体101内形成有用于存储液态气溶胶生成基质的储液腔，多孔基体1导液端12上的导液面121与储液腔相连通，多孔基体1雾化端11上的雾化面111背离储液腔，且雾化器10在雾化面111对应侧设有雾化腔。
电源装置20可包括支架201以及设置于支架201中的电池、电路板、气流传感器。雾化器10和电源装置20可通过磁吸、螺接等可拆卸的方式连接在一起，电池的正负极分别与两个电极部4电性连接，用于给发热体2供电。
可以理解地，储液腔内可存储有液态气溶胶生成基质，多孔基体1通过其毛细作用力将液态气溶胶生成基质吸附至其雾化面111上并填充于收容槽5中，当通电后，发热体2对多孔基体1供给的以及收容槽5中的液态气溶胶生成基质进行加热雾化，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从多孔基体1以及收容槽5中获得的液态气溶胶生成基质充足且均匀，雾化效果好，利于提高用户体验感。
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。
