电子雾化装置可用于基质的雾化。电子雾化装置包括相互连接的雾化组件1和电源组件2。雾化组件1用于存储基质并雾化基质以形成气溶胶。基质一般情况下为液态，但也可以是固态，或固液混合态；液态基质可以是药液、植物草叶类液体等液态基质。雾化组件1具体可用于不同的领域，比如，医疗、电子气溶胶化等。电源组件2包括 电池(图未示)、气流传感器(图未示)以及控制器(图未示)等；电池用于为雾化组件1供电，以使得雾化组件1能够雾化基质形成气溶胶；气流传感器用于检测电子雾化装置中气流变化，控制器根据气流传感器检测到的气流变化控制雾化组件1是否工作。雾化组件1与电源组件2可以是一体设置，也可以是可拆卸连接，根据具体需要进行设计。
请参阅图2-图5，图2是本申请提供的雾化组件的结构示意图，图3是图2提供的局部分解结构示意图，图4是图2中发热体的结构示意图，图5是图4中致密基体的结构示意图。
雾化组件1包括壳体10、发热座11和发热体12。壳体10有储液腔13、出气通道14和收容腔15；其中，储液腔13环绕出气通道14，发热座11位于收容腔15中。壳体10与发热座11一起形成壳体组件。储液腔13用于存储基质。出气通道14与雾化组件1的中轴线平行且一端延伸至壳体10的端面形成抽吸口16，用户通过抽吸口16抽吸。在一实施方式中，出气通道14全段与雾化组件1的中轴线平行。发热体12位于发热座11，发热体12用于雾化基质。发热体12的雾化面朝向壳体10的侧壁设置，即，发热体12的雾化面暴露于雾化腔17且与出气通道14基本平行，发热体12的雾化面与发热座11配合形成雾化腔17，雾化腔17与出气通道14连通。也就是说，发热体12雾化后的气溶胶在雾化腔17中，通过出气通道14到达抽吸口16被用户吸食。发热体12的雾化面与雾化组件1的中轴线之间的夹角小于30°。在一实施方式中，发热体12的雾化面与雾化组件1的中轴线平行。
通过使出气通道14全段与雾化组件1的中轴线平行设置，且出气通道14的一端延伸至壳体10的端面形成抽吸口16，发热体12的雾化面与雾化组件1的中轴线平行，发热体12的雾化面与发热座11配合形成的雾化腔17与出气通道14连通，发热体12雾化后的气溶胶从雾化腔17直线流动至抽吸口16被用户吸食，避免经过弯路，减少了气溶胶与壁面的接触，进而减少了冷凝液的形成；且缩短了气道长度，使得气溶胶到达用户口中的温度适宜，利于提高口感。
在一实施方式中，发热体12的雾化面与出气通道14的侧面共面或相切，以进一步使气溶胶沿直线流动至抽吸口16。当出气通道14的横截面为圆形，发热体12的雾化面与出气通道14的侧面相切；当出气通道14的横截面为方形，发热体12的雾化面与出气通道14的部分侧面共面。具体地，发热体12的雾化面与出气通道14的轴线之间的距离为第一值，出气通道14的半径(出气通道14的横截面为圆形时)为第二值，第一值与第二值相同，以使气溶胶沿着直线型的通道流出。在其他实施方式中，第一值可以大于或小于第二值。
在本实施例中，参见图4和图5，发热体12包括致密基体121和发热膜122。致密基体121包括第一表面1211以及与第一表面1211相对的第二表面1212；致密基体121上设置有多个第一微孔1213，第一微孔1213为贯穿第一表面1211和第二表面1212的通孔。发热膜122位于第一表面1211上。其中，致密基体121上设置有发热膜122的表面为雾化面，即，致密基体121的第一表面1211为雾化面，致密基体121的第二表面1212为吸液面。也就是说，致密基体121包括吸液面和与吸液面相对的雾化面，发热膜122位于雾化面；第一微孔1213为贯穿吸液面和雾化面的通孔。第一微孔1213用于将基质从吸液面导引至雾化面，第一微孔1213具有毛细作用。致密基体121的材料为致密陶瓷或玻璃；致密基体121的材料为玻璃时，玻璃为硼硅玻璃、石英玻璃或光敏铝硅酸锂玻璃。
发热膜122具有与多个第一微孔1213一一对应且相互连通的多个第二微孔1221。发热体12的发热膜122在常温(20℃～25℃)下的电阻为0.5～2欧姆。可以理解的是，致密基体121起结构支撑作用，发热体12中的发热膜122与电源组件2电连接。在电子雾化装置的功率为6瓦-8.5瓦，电池的电压范围为2.5伏-4.4伏时。。
本申请通过在致密基体121上设置多个具有毛细作用力的第一微孔1213，使得发热体12的孔隙率的大小可精确控制，提升产品的一致性。也就是说，在批量生产中，发热体12中致密基体121的孔隙率基本一致，形成于致密基体121上的发热膜122的厚度均匀，使得不同一批出厂的电子雾化装置雾化效果一致。
在其他实施例中，发热体12还可以是片状的多孔陶瓷发热体，具体根据需要进行设计。
发热座11包括第一子发热座111和第二子发热座112，第一子发热座111和第二子发热座112相互配合将发热体12夹持，以实现对发热体12的固定。具体地，第一子发热座111和第二子发热座112沿着垂直于雾化组件1轴向的方向夹持发热体12的两个表面，在垂直于发热体12的方向上固定发热体12的同时对发热体12起保护作用，提高发热体12的抗冲击能力，防止发热体12破裂。在一实施方式中，第一子发热座111和第二子发热座112有对应的凸起与卡勾配合设置；第一子发热座111与第二子发热座112通过凸起和卡勾卡扣连接。在其他实施方式中，第一子发热座111与第二子发热座112也可以通过过盈配合、磁吸等方式连接。
具体地，第一子发热座111或第二子发热座112上设置有凹槽1111。凹槽1111与储液腔13连通，发热体12设置于凹槽1111中。在一实施方式中，在第一子发热座111上设置凹槽1111，发热体12设置于凹槽1111中，发热体12的雾化面与第二子发热座112配合形成雾化腔17。在另一实施方式中，在第二子发热座112上形成有空腔(图未示)，空腔的腔壁包括相对设置的第一侧壁和第二侧壁，在空腔的第一侧壁上设置有凹槽1111，发热体12设置于凹槽1111，发热体12的雾化面与第二侧壁配合形成雾化腔17；其中，第二侧壁位于第一侧壁远离第一子发热座111的一侧。凹槽1111的设置方式可以根据具体需要进行设计，凹槽1111能够安装发热体12并使发热体12能够接触到储液腔13中的基质即可。
请参阅图6-图9，图6是图2中第一子发热座的结构示意图，图7是图6提供的第一子发热座的另一角度的结构示意图，图8是图2中第二子发热座的结构示意图，图9是图8提供的第二子发热座的另一角度的结构示意图。
参见图2、图6-图9，第一子发热座111包括顶盖1112和下座1113，第二子发热座112包括上座1121和底座1122；第一子发热座111的顶盖1112覆盖第二子发热座112的底座1122并抵持第二子发热座 112的上座1121，第二子发热座112的底座1122覆盖第一子发热座111的顶盖1112并抵持第一子发热座111的下座1113，以便于装配。可以理解，第一子发热座111的顶盖1112和下座1113可以是一体成型，也可以是通过黏胶等方式固定在一起；第二子发热座112的上座1121和底座1122可以是一体成型，也可以是通过黏胶等方式固定在一起，具体根据需要进行设计。
第一子发热座111的下座1113的侧面设置有凹槽1111，发热体12的雾化面与第二子发热座112的上座1121的侧面配合形成雾化腔17。第一子发热座111的顶盖1112上设置有下液孔1114和通气孔1115。通气孔1115的一端与雾化腔17连通，通气孔1115的另一端与出气通道14连通。下液孔1114的一端与储液腔13连通。第一子发热座111的下座1113设置有下液通道1116，下液通道1116的一端与下液孔1114的另一端连通，下液通道1116的另一端与凹槽1111连通。第二子发热座112的底座1122上设置有进气孔1123，进气孔1123与雾化腔17连通。具体地，外界气体通过进气孔1123进入雾化腔17，携带雾化腔17中的气溶胶通过通气孔1115进入出气通道14，进而到达抽吸口16被用户吸食。下液通道1116与下液孔1114可以是一个整体(下液通道与下液孔形状，孔径大小相同的时候)，也可以是分开的两个部分(下液通道与下液孔不同形状的时候)。下液通道1116与下液孔1114配合形成流体通道。
在本实施例中，下液通道1116贯穿第一子发热座111的下座1113；即，下液通道1116为贯穿下座1113的通孔。凹槽1111的底壁上设置有进液孔1117，以使凹槽1111与下液通道1116连通。可以理解，下液通道1116的结构可以根据需要进行设计，能够使凹槽1111与进液孔1117连通，进而与储液腔13连通即可。
参见图8和图9，在第二子发热座112的底座1122上设置有进气孔1123，在第二子发热座112的上座1121上设置贯穿上座1121的通孔1124，通孔1124的轴线与上座1121的高度方向垂直，通孔1124与雾化腔17连通。底座1122的端部形成台阶结构(图未示)，壳体10的端部抵接于台阶结构的台阶面上，底座1122实现对壳体 10端部的封堵。上座1121与壳体10之间存在间隙，进气孔1123暴露于该间隙，通孔1124通过该间隙与进气孔1123连通。可以理解，在其他实施方式中，在第二子发热座112的底座1122上设置有进气孔1123，进气孔1123为贯穿底座1122的通孔，且进气孔1123的轴线与雾化组件1的中轴线平行，进气孔1123的设置方式可以根据需要进行设计，能够实现外界气体与雾化腔17连通即可。
参见图2、图3、图6-图9，雾化组件1还包括隔离塞18，隔离塞18部分设置于下液通道1116和/或下液孔1114中。隔离塞18处于第一位置时，储液腔13与凹槽1111不连通；隔离塞18处于第二位置时，储液腔13与凹槽1111连通。即，隔离塞18处于第一位置时，隔离塞18将凹槽1111底壁的进液孔1117封堵或将下液孔1114封堵，使储液腔13与凹槽1111不连通；隔离塞18处于第二位置时，隔离塞18并未封堵凹槽1111底壁的下液孔1114和进液孔1117，使储液腔13与凹槽1111连通。
隔离塞18包括密封部181和拉杆182；密封部181设置于下液通道1116和/或下液孔1114中，且形状与下液通道1116和/或下液孔1114的形状相匹配。拉杆182设置于密封部181远离储液腔13的一端。第二子发热座112的底座1122上设置有衔接孔1125，衔接孔1125对应下液通道1116设置。拉杆182设置于衔接孔1125中，以与密封部181连接，且拉杆182的端部伸出于壳体10背离抽吸口16的一侧。其中，密封部181的材质为硅胶，拉杆182的材质为硅胶、塑胶、木材等，密封部181和拉杆182的连接方式可以根据需要进行设计，例如一体成型。
通过设置隔离塞18，在出货时隔离塞18堵住进液孔1117使其处于第一位置，降低运输及存储漏液风险，使用时将隔离塞18拉到底部使其处于第二位置，基质能够进入凹槽1111。将隔离塞18拉到底部使其处于第二位置后，也可以将拉杆182切断(用户可以把拉杆182拉断与密封部181分离)，便于雾化组件1与电源组件2电连接。
可以理解，当密封部181的顶面与储液腔13的底壁之间的距离为第一值，进液孔117靠近储液腔13的一端与储液腔13的底壁之间 的距离为第二值，第一值大于第二值时，若密封部181的长度小于进液孔1117的高度，会有基质从密封部181的顶面进入进液孔1117流至发热体12靠近雾化腔17的一侧，再从发热体12靠近雾化腔17的一侧流至发热体12的另一侧，进而从下液通道1116漏出，即，密封部181的长度小于进液孔1117的高度存在漏液的风险。因此，将密封部181的长度设置为不小于进液孔1117的高度。其中，密封部181的长度为沿雾化组件1长度方向上其顶面与底面之间的距离；进液孔1117的高度为进液孔1117靠近储液腔13的一端与进液孔远离储液腔13的一端之间的距离。
参见图3，雾化组件1还包括密封件19，密封件19设置于发热体12与凹槽1111的底壁之间。密封件19的中部设置有连通孔191，以使发热体12至少部分暴露，使得发热体12可以接触到基质。具体地，连通孔191使发热体12的致密基体121上的多个第一微孔1213中的至少部分暴露，第一微孔1213通过连通孔191、凹槽1111与储液腔13连通，第一微孔1213将基质从吸液面导流至雾化面，被雾化面上的发热膜122雾化。通过在发热体12与凹槽1111的底壁之间设置密封件19，以对发热体12进行缓冲，提高发热体12的抗冲击能力。
雾化组件1还包括导液体20，导液体20设置于发热体12与凹槽1111的底壁之间。导液体20为导液棉或多孔陶瓷等导液材料。通过设置导液体20，能够避免基质的液面低于进液孔1117的顶部时发热体12吸液不均匀，导液体20可以吸收下液通道1116底部的液体平均分配供液到发热体12的吸液面，有利于口感的一致性。导液体20设置于密封件19远离发热体12的一侧。
请参阅图10，图10是图3提供的局部放大图。
发热体12还包括电极123，电极123设置于雾化面，发热膜122与电极123电连接。雾化组件1还包括弹片21，例如金属弹片。弹片21的一端与电极123连接，另一端用于与电源组件2连接。具体地，第二子发热座112的底座1122上设置有安装孔(图未示)，弹片21的另一端设置于安装孔并暴露于雾化组件1的端部，以与电源 组件2电连接。在一实施方式中，弹片21为金属片，通过注塑成型将弹片21嵌设于第二子发热座112内，便于装配。具体地，弹片21的一端延伸出第二子发热座112并弯折形成弹性接触端，以用于与电极123抵接，弹片21的另一端垂直弯折形成平行于第二子发热座112底面的接触端并于第二子发热座112底面暴露，以用于与电源组件2的顶针抵接。可以理解，弹片21固定于第二子发热座112的方式可以根据需要进行设计，本申请对此并不限定。
下面对发热体12的致密基体121的材料为玻璃进行具体介绍。
致密基体121的厚度为0.1毫米-1毫米。致密基体121的厚度大于1毫米时，无法满足供液需求，导致气溶胶量下降，且造成的热损失多，设置第一微孔1213的成本高；致密基体121的厚度小于0.1毫米时，无法保证致密基体121的强度，不利于提高电子雾化装置的性能。致密基体121的厚度为0.2毫米-0.5毫米。致密基体121上第一微孔1213的孔径为1微米-100微米。第一微孔1213的孔径小于1微米时，无法满足供液需求，导致气溶胶量下降；第一微孔1213的孔径大于100微米时，基质容易从第一微孔1213内流出至第一表面1211造成漏液，导致雾化效率下降。第一微孔1213的孔径为20微米-50微米。可以理解的是，致密基体121的厚度和第一微孔1213的孔径根据实际需要进行选择。
致密基体121厚度与第一微孔1213孔径的比例范围为20:1到3:1之间。当致密基体121的厚度与第一微孔1213的孔径的比例大于20:1时，通过第一微孔1213的毛细作用力供给的基质难以满足发热体12的雾化需求量，容易导致干烧，且单次雾化产生的气溶胶量下降；当致密基体121的厚度与第一微孔1213的孔径的比例小于3:1时，基质容易从第一微孔1213内流出至第一表面1211，基质浪费，导致雾化效率下降，进而使得总气溶胶量降低。
相邻两个第一微孔1213之间的孔中心距与第一微孔1213的孔径的比例为3:1-1.5:1之间，以使致密基体121上的第一微孔1213在满足供液能力的前提下，尽可能提升致密基体121的强度；相邻两个第一微孔1213之间的孔中心距与第一微孔1213的孔径的比例为3:1-2:1。
在一个具体实施例中，致密基体121的厚度与第一微孔1213的孔径的比例为15:1-5:1，相邻两个第一微孔1213之间的孔中心距与第一微孔1213的孔径的比例为3:1-2.5:1。
以上所述仅为本申请的部分实施例，并非因此限制本申请的保护范围，凡是利用本申请说明书及附图内容所作的等效装置或等效流程变换，或直接或间接运用在其它相关的技术领域，均同理包括在本申请的专利保护范围内。
