雾化器1与主机2可以是一体设置，也可以是可拆卸连接，可以根据具体需要进行设计。
请参阅图2和图3，图2是图1提供的电子雾化装置的雾化器的结构示意图，图3是图2提供的雾化器的顶座的结构示意图。
雾化器1包括壳体11、雾化座12和发热体13。壳体11的一端为敞口端，雾化座12设于壳体11内且封堵该敞口端，雾化座12与壳体11配合形成储液腔10，储液腔10用于存储气溶胶生成基质。雾化座12包括顶座121和底座122，顶座121和底座122配合形成安装腔120，安装腔120用于安装发热体13。即，发热体13设于安装腔120内，发热体13同雾化座12一起设于壳体11内。顶座121上设有下液孔1211，发热体13通过下液孔1211与储液腔10流体连通，发热体13用于雾化气溶胶生成基质生成气溶胶。其中，发热体13与安装腔120的底壁之间间隔设置形成雾化腔(图未标)，即发热体13远离储液腔10的表面与安装腔120的腔壁配合形成雾化腔。壳体11具有出雾通道111，顶座121上设有出雾孔1210，出雾孔1210与安装腔120连通，即，出雾孔1210与雾化腔连通；具体，顶座121 上设有两个下液孔1211，分别位于出雾孔1210的两侧。发热体13雾化生成的气溶胶释放于雾化腔中，通过出雾孔1210流至出雾通道111，用户通道出雾通道111的端口吸食气溶胶。
可以理解，在本实施例中，雾化座12由顶座121和底座122上下装配形成；在其他实施例中，雾化座12也可以由两个结构件左右装配形成，具体根据需要进行设计。也就是说，本申请并不限定雾化座12的结构，仅以顶座121和底座122形成的雾化座12为例对下液孔1211的具体设置进行详细介绍。
在本申请实施例中，下液孔1211为阶梯孔，下液孔1211靠近储液腔10部分的当量直径大于下液孔1211远离储液腔10部分的当量直径。由于发热体13通过下液孔1211与储液腔10流体连通，当发热体13靠近储液腔10的表面存在气泡时，可以将气泡导向至储液腔10，来避免气泡附着在发热体13靠近储液腔10的表面堵塞发热体13的毛细孔，进而避免气泡造成的供液不足问题。利用气泡易于向开阔空间流动的特性，本申请将下液孔1211设为阶梯孔，且下液孔1211靠近储液腔10部分的当量直径大于下液孔1211远离储液腔10部分的当量直径，利于将发热体13靠近储液腔10表面的气泡导向至储液腔10，即，易于使气泡从下液孔1211脱离进入储液腔10，避免了气泡造成的供液不足，降低了发热体13烧焦或烧断的风险。另外，在倒抽时，即储液腔10位于下液孔1211的下方时，储液腔10内的气体在下液孔1211靠近储液腔10的部分形成大直径的气泡，由于下液孔1211为阶梯孔，下液孔1211远离储液腔10部分的当量直径要更小，气泡难以进入下液孔1211远离储液腔10部分，从而能够阻挡下液孔1211内的气溶胶生成基质流至储液腔10，起到锁液的效果，实现即使倒抽也可以为发热体13供液。
可以理解，下液孔1211为阶梯孔指的是下液孔1211可以划分为多段，每段的当量直径相同，不同段的当量直径不同且沿着某一方向呈增大趋势或减小趋势。下液孔1211靠近储液腔10部分的当量直径大于下液孔1211远离储液腔10部分的当量直径，即，沿着从储液腔10流向发热体13的方向，下液孔1211不同段的当量直径呈减小趋势。下液孔1211不同段的横截面形状不限，可以是规则形状，也可以是非规则形状，具体根据需要进行设计。
具体地，下液孔1211的孔壁具有至少一层阶梯A以形成阶梯孔，一层阶梯形成一段子下液孔1212。也就是说，沿着从储液腔10流向发热体13的方向，在下液孔1211的孔壁没有阶梯A时，其当量直径一致，由于在下液孔1211的孔壁设有至少一层阶梯A，使得下液孔1211形成阶梯孔。下液孔1211靠近储液腔10的端口的当量直径大于阶梯A形成的子下液孔1212的当量直径，阶梯A与下液孔1211靠近储液腔10的端口间隔设置，使得下液孔 1211靠近储液腔10的部分为开阔空间，以利于将气泡导向至储液腔10。本申请中，下液孔1211除去阶梯A围设形成的子下液孔1212之外的下液孔段尺寸与下液孔1211靠近储液腔10的端口尺寸相同；阶梯A指的是在下液孔1211的孔壁设置后续介绍的翅片1213或凸起1214的结构件而形成的台阶。
可选的，形成阶梯A的结构件与顶座121一体成型。
当下液孔1211的孔壁具有一层阶梯A时，阶梯A形成的子下液孔1212的当量直径小于下液孔1211靠近储液腔10的端口的当量直径，阶梯A靠近储液腔10的端面与下液孔1211靠近储液腔10的端口之间的这一段的当量直径一致(如图3所示)。
当下液孔1211的孔壁具有多层阶梯A时，多层阶梯A形成多个子下液孔1212。沿着从储液腔10流向发热体13的方向，多个子下液孔1212的当量直径逐渐减小。
在一实施方式中，下液孔1211靠近储液腔10的端口的当量直径不小于1mm；可以理解，下液孔1211靠近储液腔10的端口的当量直径小于1mm时，尺寸太小不利于下液，使得气溶胶生成基质的供液速度较慢，存在无法满足发热体13雾化量的问题。可选的，下液孔靠近储液腔10的端口的当量直径为2mm-4mm。
在一实施方式中，子下液孔1212的当量直径为0-2mm；可以理解，当用户将雾化器1倒置使用时，储液腔10内的气泡有流向至靠近发热体13的一侧的趋势，由于储液腔10内的气泡的直径大于2mm，将子下液孔1212的当量直径设为小于2mm，可以避免储液腔10内的气泡通过下液孔1211附着至发热体13靠近储液腔10的表面，进而避免了气泡导致的供液不足问题。可选的，子下液孔1212的当量直径为1-1.8mm。
在一实施方式中，下液孔1211靠近储液腔10的端口的当量直径比子下液孔1212的当量直径大0.1mm-5mm，以使下液孔1211靠近储液腔10的部分形成明显的开阔空间。可选的，下液孔1211靠近储液腔10的端口的当量直径比子下液孔1212的当量直径大0.2mm-2mm。
请参阅图4和图5，图4是图3提供的顶座的下液孔第一实施方式的结构示意图，图5是图4提供的顶座的俯视图。
在下液孔1211第一实施方式中，下液孔1211的孔壁具有多个翅片1213，多个翅片1213沿着下液孔1211的孔壁的周向间隔设置。翅片1213的长度方向与下液孔1211的轴线平行设置。多个翅片1213配合形成至少一层阶梯A。可以理解，由于多个翅片1213之间是间隔设置的，气溶胶生成基质可以从翅片1213之间的间隙流至发热体13；通过下液孔1211的孔壁设有翅片1213，增加了下液面积。当翅片1213的材质为塑胶时，翅片1213与气溶胶 生成基质的接触角比较小，润湿性好，利于气溶胶生成基质流至发热体13。
可选的，相邻的两个翅片1213之间的间隔面积小于子下液孔1212的横截面面积。其中，横截面指的是垂直于下液孔1211的轴线方向的截面。通过上述设置，当气泡占据子下液孔1212时，气溶胶生成基质可以利用相邻的两个翅片1213之间的毛细力流至发热体13；即，气泡通过子下液孔1212排出进入储液腔10，储液腔10内的液体通过相邻的两个翅片1213之间的间隙流至发热体13。
可选的，多个翅片1213沿着下液孔1211的孔壁的周向均匀间隔设置。
可选的，多个翅片1213沿着下液孔1211的孔壁的周向非均匀间隔设置，下液孔1211的孔壁越靠近出雾孔1210一侧，翅片1213的分布密度越大，使得下液孔1211内越远离出雾孔1210，其空间越广阔，利用气泡易于向开阔空间流动的特性，实现定向导走气泡。由于下液孔1211远离储液腔10的端口被底壁封堵，下液孔1211的出液口(图未示)设置于靠近出雾孔1210一侧的侧壁。通过将气泡导向至下液孔1211内远离出雾孔1210的一侧，使得下液孔1211靠近出雾孔1210的部分仍可以使气溶胶生成基质流至发热体13，保证持续供液和供液充足。
可选的，每个翅片1213靠近储液腔10的端面为平面。
可选的，每个翅片1213靠近储液腔10的端面为平面，每个翅片1213与下液孔1211靠近储液腔10的端口均间隔设置；多个翅片1213靠近储液腔10的端面与下液孔1211靠近储液腔10的端口之间的距离相同；每个翅片1213远离下液孔1211的孔壁的端面为平面；多个翅片1213配合形成一层阶梯A，多个翅片1213远离下液孔1211的孔壁的端面围设形成一段子下液孔1212；子下液孔1212的当量直径小于下液孔1211靠近储液腔10的端口的当量直径(如图4和图5所示)。参见图4，多个翅片1213的顶端(靠近储液腔10的一端)与下液孔1211靠近储液腔10的端口间隔设置，翅片1213靠近储液腔10的端面与下液孔1211靠近储液腔10的端口之间为开阔空间，以利于将气泡导向至储液腔10。多个翅片1213的底端可以均直接设置于下液孔1211的底壁上。
可选的，每个翅片1213靠近储液腔10的端面为平面，每个翅片1213与下液孔1211靠近储液腔10的端口均间隔设置；多个翅片1213靠近储液腔10的端面与下液孔1211靠近储液腔10的端口之间的距离相同；每个翅片1213远离下液孔1211的孔壁的端面为台阶面(图未示)；多个翅片1213配合形成多层阶梯A，多层阶梯A形成多个子下液孔1212；沿着从储液腔10流向发热体13的方向，多个子下液孔1212的当量直径逐渐减小。
示例性的，每个翅片1213远离下液孔1211的孔壁的端面包括第一平面M和第二平面 N，第一平面M与下液孔1211的轴线之间的距离大于第二平面N与下液孔1211的轴线之间的距离，即，第一平面M和第二平面N配合形成台阶面(如图6所示，图6是图4提供的下液孔的翅片另一实施方式的结构示意图)。每个翅片1213还包括连接第一平面M和第二平面N的连接面P，连接面P为平面。多个翅片1213靠近储液腔10的端面与下液孔1211靠近储液腔10的端口之间的距离相同，多个连接面P与下液孔1211靠近储液腔10的端口之间的距离相同，多个翅片1213配合形成两层阶梯A，多个第一平面M围设形成一段子下液孔1212，多个第二平面N围设形成另一段子下液孔1212。通过将翅片1213做如上设置，利于将气溶胶生成基质导引至发热体13。需要说明的是，图中虚线为下液孔1211的轴线。
可以理解，多个翅片1213配合形成多层阶梯A，可以通过设置翅片1213远离下液孔1211的孔壁的端面为台阶面来形成多层阶梯A，阶梯A的层数与台阶面包括的高低不同的平面的个数相同，具体根据需要进行设计。
请参阅图7，图7是图4提供的下液孔的翅片又一实施方式的结构示意图。可选的，每个翅片1213靠近储液腔10的端面为平面，每个翅片1213与下液孔1211靠近储液腔10的端口均间隔设置。多个翅片1213包括至少一个第一翅片1213a和至少一个第二翅片1213b，第一翅片1213a靠近储液腔10的端面与下液孔1211靠近储液腔10的端口之间的距离为第一值，第二翅片1213b靠近储液腔10的端面与下液孔1211靠近储液腔10的端口之间的距离为第二值，第一值小于第二值，第一值大于零。下液孔1211的孔壁靠近出雾孔1210的部分设有第一翅片1213a，下液孔1211的孔壁远离出雾孔1210的部分设有第二翅片1213b；即，第一翅片1213a与出雾孔1210的轴线之间的距离小于第二翅片1213b与出雾孔1210的轴线之间的距离。
具体地，至少一个第一翅片1213a和至少一个第二翅片1213b配合形成两层阶梯A。第一翅片1213a与第二翅片1213b间隔设置；当第一翅片1213a的数量为多个时，多个第一翅片1213a间隔设置；当第二翅片1213b的数量为多个时，多个第二翅片1213b间隔设置。第一翅片1213a包括第一部分(图未标)和第二部分(图未标)，第二部分位于第一部分远离储液腔10的一侧；多个第一翅片1213a的第一部分远离下液孔1211的孔壁的端面与下液孔1211的部分孔壁围设形成一段子下液孔1212；多个第一翅片1213a的第二部分远离下液孔1211的孔壁的端面与多个第二翅片1213b远离下液孔1211的孔壁的端面围设形成另一段子下液孔1212。
通过在下液孔1211的孔壁靠近出雾孔1210的部分设有第一翅片1213a，下液孔1211的孔壁远离出雾孔1210的部分设有第二翅片1213b，相对于第一翅片1213a靠近储液腔10 的端面与下液孔1211靠近储液腔10的端口之间的空间，第二翅片1213b靠近储液腔10的端面与下液孔1211靠近储液腔10的端口之间的空间更为广阔，利用气泡易于向开阔空间流动的特性，实现定向导走气泡。通过将气泡导向至下液孔1211内远离出雾孔1210的一侧，使得下液孔1211靠近出雾孔1210的部分仍可以使气溶胶生成基质流至发热体13，保证持续供液和供液充足。
可以理解，多个翅片1213配合形成多层阶梯A，可以通过设置多种不同高度的翅片1213形成多层阶梯A，阶梯A的层数与不同高度的翅片1213的种数相同，具体根据需要进行设计。
请参阅图8，图8是图3提供的顶座的下液孔第二实施方式的结构示意图。
在下液孔1211第二实施方式中，下液孔1211的孔壁设有凸块1214，凸块1214沿着下液孔1211的孔壁的周向延伸，凸块1214形成至少一层阶梯A。
可选的，凸块1214沿着下液孔1211的孔壁的周向整周设置。凸块1214远离下液孔1211的孔壁的端面围设形成至少一段子下液孔1212。
可选的，凸块1214沿着下液孔1211的孔壁的周向部分设置，即，凸块1214没有环绕下液孔1211的孔壁的一整周。凸块1214远离下液孔1211的孔壁的端面与下液孔1211的部分孔壁围设形成至少一段子下液孔1212(如图8所示)。具体地，下液孔1211的孔壁远离出雾孔1210的部分设有凸块1214；由于下液孔1211远离储液腔10的端口被底壁封堵，下液孔1211的出液口(图未示)设置于靠近出雾孔1210一侧的侧壁，以使在导走气泡的同时，气溶胶生成基质可以通过下液孔1211靠近出雾孔1210的部分空间流至发热体13，保证持续供液和供液充足。
可选的，凸块1214靠近储液腔10的端面为平面。
可选的，凸块1214远离下液孔1211的孔壁的端面为台阶面(如图8所示)。凸块1214形成多层阶梯A，多层阶梯A形成多个子下液孔1212；沿着从储液腔10流向发热体13的方向，多个子下液孔1212的当量直径逐渐减小。
示例性的，参见图8，凸块1214靠近储液腔10的端面为平面。凸块1214远离下液孔1211的孔壁的端面包括第三平面a和第四平面b，第三平面a与下液孔1211的轴线之间的距离大于第四平面b与下液孔1211的轴线之间的距离，即，第三平面a和第四平面b配合形成台阶面。凸块1214还包括连接第三平面a和第四平面b的连接面c，连接面为平面。凸块1214形成两层阶梯A，第三平面a和下液孔1211的部分孔壁围设形成一段子下液孔1212，第四平面b和下液孔1211的部分孔壁围设形成另一段子下液孔1212。
可以理解，凸块1214形成多层阶梯A，可以通过设置凸块1214远离下液孔1211的孔壁的端面为台阶面来形成多层阶梯A，阶梯A的层数与台阶面包括的高低不同的平面的个数相同，具体根据需要进行设计。
请参阅图9，图9是图2提供的雾化器的一局部放大结构示意图。
进一步，在下液孔1211的孔壁靠近储液腔10的部分设有疏气溶胶生成基质层B，即，疏气溶胶生成基质层B不与气溶胶生成基质浸润。疏气溶胶生成基质层B环绕下液孔1211的孔壁的周向整周设置，避免下液孔1211靠近储液腔10的端口在下液过程中形成液膜，保证下液顺畅，进而避免供液不足的问题。并且，雾化器1在倾斜或翻转过程中，下液孔1211内的气溶胶生成基质的表面更易与壳体11内的气溶胶生成基质的表面断开，阻碍壳体11的内表面与疏气溶胶生成基质层B围设形成的孔靠近子储液腔101的端口之间形成连续的液膜，使得疏气溶胶生成基质层B围设形成的孔靠近子储液腔101的端口形成的液膜具有的表面张力能够实现锁液功能。
可以理解，疏气溶胶生成基质层B围设形成的形状的当量直径大于子下液孔1212的当量直径，以形成阶梯A，利于将下液孔1211内的气泡导引至储液腔10。
在本实施例中，雾化器1还包括密封件14，密封件14设于顶座121的侧面和顶座121远离底座122的表面，且密封件14位于顶座121远离底座122的表面的部分延伸至下液孔1211的孔壁形成疏气溶胶生成基质层A。即，密封件14设于雾化座12的侧面和雾化座12靠近储液腔10的表面，且密封件14位于雾化座12靠近储液腔10的表面的部分延伸至下液孔1211的孔壁形成疏气溶胶生成基质层。可选的，密封件14的材质为硅胶。
具体地，密封件14包括第一侧壁141、顶壁142和第二侧壁143，第一侧壁141和第二侧壁143位于顶壁142的同一侧；第一侧壁141设于顶座121的侧面，顶壁142设于顶座121远离122底座的表面，第二侧壁143设于下液孔1211的孔壁，第二侧壁143的端部与阶梯A接触或间隔设置，即子下液孔1212内没有第二侧壁143。
请参阅图10和图11，图10是图2提供的雾化器的壳体的仰视结构示意图，图11是图2提供的雾化器的另一角度结构示意图。
在本实施例中，壳体11的内部具有隔片112，隔片112将储液腔10分隔为两个子储液腔101。可选的，隔片112与壳体11一体成型。具体地，隔片112与密封件14接触，以将两个子储液腔101完全分隔开来，形成两个相互独立的子储液腔101。两个下液孔1211与两个子储液腔101一一对应连通，即，一个下液孔1211连通一个子储液腔101。发热体13与顶座121配合形成发热体吸液腔130，发热体吸液腔130将两个下液孔1211连通。两个 子储液腔101分别为第一子储液腔101、第二子储液腔101；两个下液孔1211分别为第一下液孔1211和第二下液孔1211，第一子储液腔101、第一下液孔1211、发热体吸液腔130、第二下液孔1211以及第二子储液腔101依次连接形成U形结构；雾化器1倒置时，两个子储液腔101内的气体和/或气溶胶生成基质不串流。在其他实施例中，也可以不设置隔片112，将壳体11的内表面与出雾通道111的外表面相切并连接，从而将壳体11与顶座121围设形成的空间分隔成相互独立的两个子储液腔101。
具体地，顶座121靠近底座122的一端具有台阶槽(图未标)，台阶槽包括靠近下液孔1211的第一凹槽(图未标)和远离下液孔1211的第二凹槽(图未标)；第二凹槽的尺寸大于第一凹槽的尺寸；发热体13设置于第二凹槽内并覆盖第一凹槽，发热体13与第一凹槽配合形成发热体吸液腔130。
通过上述设置，雾化器1在倾斜或翻转的过程中，两个子储液腔10内的气体无法突破下液孔1211靠近储液腔10的端口的表面张力，无法实现两个子储液腔101之间的气体流通。由于两个子储液腔101之间无法实现气体流通，两个子储液腔101内的气溶胶生成基质和气体只能在各自区域内进行流动，而其整体若要向某一侧流动，则必然受到两侧气体的阻力，因此在下液孔1211靠近储液腔10的端口的表面张力和两个子储液腔101内气体压力的作用下，发热体吸液腔130内的气溶胶生成基质只能滞留在发热体吸液腔130内，以及下液孔1211内的气溶胶生成基质只能滞留在下液孔1211内，从而达到实现倾斜和倒置后在发热体吸液腔130和下液孔1211内储液的效果，保证倒抽时的供液充足，短时间内不会出现发热体13烧焦或烧断的现象。
继续参见图2，在本实施例中，发热体13为片状，发热体13包括导液基体(图未标)和发热元件(图未标)，发热元件设于导液基体的表面，导液基体用于导引气溶胶生成基质，发热元件用于雾化气溶胶生成基质。导液基体的材料可以为多孔陶瓷，也可以为致密材料；当导液基体的材料为致密材料，可以为石英、玻璃、致密陶瓷或硅。在其他实施例中，发热体13可以为现有的多孔陶瓷发热体或棉芯发热体，具体根据需要进行设计。
本申请还对采用图4提供的下液孔1211的设置方式的雾化器1进行了实验，实验结果如图12所示，图12是本申请提供的一实验结果图。本申请还对采用图6提供的下液孔1211的设置方式的雾化器1进行了实验，实验结果如图13所示，图13是本申请提供的另一实验结果图。通过图12和图13可以得知，本申请提供的雾化器1在倒置时，储液腔10内的气泡卡在下液孔1211靠近储液腔10的端口，可以避免气泡附着至发热体13靠近储液腔10的表面，也就避免了发热体13靠近储液腔10的表面局部空液的问题，且储液腔10的设置 方式及发热体吸液腔130的设置，使得倒抽至少8口不会烧断发热体13。
本申请还对两个子储液腔101、两个下液孔1211以及发热体吸液腔130形成U形结构的锁液能力进行了实验。实验证明，U型结构倒置放最长两天没问题，如无强烈外力震荡不会导致液体垮掉，具有较好的锁液能力。
以上仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
