一同参阅图11，电极113在一些实施例中可采用金属片等弹性导电材料一体弯折制成，其可包括固定于底座本体111中且中部部分暴露于底座本体111底面的U型第一导电端1131以及与第一导电端1131相连且突出于底座本体111顶面且朝一侧倾斜的第二导电端1132，第一导电端1131用于与电源装置2电性连接，第二导电端1132弹性抵压在雾化组件30上。
再如图9所示，底座11在一些实施例中还可包括贯通底座本体111上下的进气通道114、设置于底座本体111顶面且位于该进气通道114的出气口附近的导流结构115以及分别设置于底座本体111顶面两相对端的一对卡扣臂116。该进气通道114用于供周围环境空气进入雾化腔120中，该导流结构115用于将气流导向雾化组件30。该一对卡扣臂116用于分别与该外壳21的两个卡槽216相卡合。进气通道114的延伸方向在一些实施例中可与雾化器1的纵轴线X相平行。
进气通道114的横截面在一些实施例中可呈长方形，从而形成纵长狭缝。进气通道114在一些实施例中可包括位于下部且沿纵向延伸的进气段1141、位于上部且沿纵向延伸的出气段1143以及将进气段1141和出气段1143相连通的过渡段1142。优选地，进气段1141、过渡段1142和出气段1143三者在宽度方向的两个壁面以及厚度方向的一个壁面是齐平的，以便于一体注塑成型过程中的脱模。
在一些实施例中，进气段1141和出气段1143均可呈长方体状，过渡段1142则可呈楔形体状。其中，进气段1141的厚度大于出气段1143的厚度，使得进气段1141的横截面积大于出气段1143的横截面积，以让吸入的气体经由出气段1143流出时被加速，而能更好地吹向雾化组件30。
在一些实施例中，进气通道114设置成上述的阶梯状，且优选地出气段1143的长度为进气通道114整个长度的五分之一到三分之一，还可方便进气通道114的成型。因为在底座本体111的一体成型过程中，如果整个进气通道114的厚度都如出气段1143那么薄，则成型该进气通道114用的模具将会又薄又长。在一体注塑等成型过程中，模具受压后容易变形或断裂，从而无法形成合格的进气通道114。而成型上述进气通道114的模具，只有与出气段1143对应部分的厚度较小，且这部分的长度为整个模具长度的五分之一到三分之一，其他部分相对较厚，从而可以大幅地提升了整个模具的抗变形能力，在保证气道狭小的同时，还保证了模具的可靠性。
导流结构115在一些实施例中可包括位于出气段1143的出气口正上方的导流面1151，该导流面1151可为朝向雾化组件30的方向倾斜的平面。可以理解地，进气通道114的横截面并不局限于长方形，其也可以呈纵长跑道型、纵长椭圆形等纵长狭缝，其也可以圆形、正方形等柱状细缝形状。
再如图3及图4所示，雾化腔体12在一些实施例中可呈筒状，并可沿纵向一体成型于底座本体111的顶面。雾化腔体12在一些实施例可包括在周向上依序连接的第一侧壁121、第二侧壁123、第三侧壁125以及第四侧壁127，这些侧壁一道界定出一个大致呈长方体状的雾化腔120。雾化腔体12的第一侧壁121、第二侧壁123以及第四侧壁127分别与外壳21的第一侧壁211、第二侧壁213和第四侧壁217相对，且均形成有间隙，这些间隙在一些实施例中相互连通。第一侧壁121、第二侧壁123以及第四侧壁127在一些实施例中可均包括平坦的外表面。
雾化腔体12的第三侧壁125的外壁面可紧贴在壳体20的外壳21的第三侧壁215的内壁面上，其上开设有沿厚度方向贯通的避让孔1250（如图10所示）。该避让孔1250用于方便雾化座10的成型，第二密封件60封堵于该避让孔1250中，以防止液体泄露至雾化腔120中。在一些实施例中，第三侧壁125的外壁面可呈弧形，以更好地与外壳21的第三侧壁215的内壁面紧贴。
如图8及图9所示，雾化腔体12的第一侧壁121在一些实施例可包括用于收容雾化组件30的安装部1210以及用于将该安装部1210与雾化腔120相连通的穿孔1212，该安装部1210在一些实施例中可为凹槽，以供雾化组件30嵌置。该安装部1210在一些实施例中可由该第一侧壁121的外表面朝远离外壳21的第一侧壁211的方向凹陷而成。穿孔1212在一些实施例中可形成于安装部1210的槽底中部，使得安装部1210的槽底呈环形。穿孔1212的形状和尺寸可与雾化组件30的雾化面313的形状和尺寸相适配，从而让雾化组件30的雾化面313完全暴露于雾化腔120中。底座11的电极113的第二导电端1132伸入到穿孔1212中与雾化组件30弹性抵接。第二侧壁123以及第四侧壁127的外表面在一些实施例中可分别设置卡台122，以与卡扣件40相卡扣。第一侧壁121的外表面在一些实施例中可为平面。
安装部1210的槽底所在的平面在一些实施例中可与雾化器1的纵轴线X相平行，以便雾化组件30安装于安装部1210中，其雾化面313也与雾化器1的纵轴线X相平行。可以理解地，安装部1210的槽底所在的平面并不局限于与雾化器1的纵轴线X相平行，其也可以与该纵轴线X略呈一夹角，且该夹角优选地为小于30度的夹角。
再如图8所示，连接腔体13在一些实施例可包括在周向上依序连接的第一侧壁131、第二侧壁133、第三侧壁135以及第四侧壁137。该第一侧壁131、第二侧壁133、第三侧壁135以及第四侧壁137一道界定出一个圆柱形的容腔130，以供第一密封件50嵌置于其中。连接腔体13在一些实施例中可沿纵向一体成型于雾化腔体12的顶部，且其第三侧壁135与雾化腔体12的第三侧壁125在一个垂直面上。连接腔体13的第一侧壁131到第三侧壁135的距离大于雾化腔体12的第一侧壁121到第三侧壁125的距离。
一同参阅图3，该第一侧壁131和第三侧壁135的外壁面分别紧抵于外壳21的第一侧壁211和第三侧壁215的内表面，将储液空间70分隔出一个位于连接腔体13下方的汇集部71以及位于连接腔体13上方的储液仓72。汇集部71由雾化腔体12与外壳21的第一侧壁211、第二侧壁213和第四侧壁217之间的间隙形成，并呈C型围绕雾化腔体12。
一同参阅图4，连接腔体13的第二侧壁133和第四侧壁137分别与外壳21的第二侧壁213和第四侧壁217相对，且分别形成两个间隙，该两个间隙将汇集部71和储液仓72相连通，分别形成液体从储液仓72进入汇集部71的第一下液口73和第二下液口74。
在一些实施例中，连接腔体13的第一侧壁131与第二侧壁133衔接处的下端角落以及第一侧壁131与第四侧壁137衔接处的下端角落均被圆弧面过渡，以让液体能够更顺畅地从储液仓72进入汇集部71,并减少下液过程中气泡在汇集部71中的粘附停留，防止或减少气泡粘附在发热体31上造成的干烧问题的产生。
连接腔体13与雾化腔体12连接处在一些实施例可设有台阶132，该台阶的顶面形成有与雾化腔120相连通且呈水平延伸的具有毛细作用力的第一导气槽1320。连接腔体13的第三侧壁135在一些实施例中可包括形成于内表面的纵向延伸的具有毛细作用力的第二导气槽1351，该第二导气槽1351的下端与该第一导气槽1320相连通。该第三侧壁135在一些实施例中还可包括形成于外表面的纵向延伸的具有毛细作用力的第三导气槽1353以及贯穿该第三侧壁135以将该第三导气槽1353与该第二导气槽1351相连通的导气孔1352。该第三导气槽1353的上端与储液空间70的储液仓72相连通。第一导气槽1320、第二导气槽1351、导气孔1352以及第三导气槽1353一道形成雾化器1的换气通道，以实现储液空间70内的气液平衡。
在一些实施例中，雾化座10的由底座本体111、雾化腔体12以及连接腔体13构成的雾化座主体可采用一体注塑成型。如此，雾化腔120的形成、储液空间70的储液部的分隔均可主要由单个零件（雾化座主体）实现，极大地降低了雾化主体100的零部件数量，提升了雾化主体100的组装效率，并降低了整个雾化主体100的制造成本。雾化座主体一体成型后，减少了零部件之间衔接间隙，也降低了漏液风险。
再如图9所示，第一密封件50在一些实施例中可采用硅胶等软质材料制成，其可包括筒状本体51以及形成于筒状本体51的上侧缘的凸缘53。筒状本体51的外径与连接腔体13的容腔130的内径相适配，以便筒状本体51能够沿轴向紧密地塞设于该容腔130中。筒状本体51的下端面紧抵于台阶132的顶面上。筒状本体51包括一个贯通的中心通孔510，以供壳体20的导气管道22插入后与雾化腔120相连通。第一密封件60在一些实施例中也采用硅胶等软质材料制成，并呈块状。
如图12所示，雾化组件30在一些实施例中可包括片状发热体31以及结合于该片状发热体31周缘的方框型软质密封件32。片状发热体31在一些实施例中可呈方形片状,其可包括片状基体311以及形成于该基体311的雾化面313上的的发热层312。该基体311可以是具有微孔阵列的玻璃或者致密陶瓷，也可以是片状的多孔陶瓷。密封件32在一些实施例中还可与发热体31一体注塑成型。密封件32在另一些实施例中还可采用两个或两个以上的结构拼接而成。
再如图9和图10所示，卡扣件40在一些实施例可采用金属片一体加工成型，其包括带有开孔410的卡扣本体41以及分别连接于该卡扣本体41两相对侧的第一扣臂42和第二扣臂43。卡扣本体41抵压在雾化组件30的外侧，第一个扣臂42和第二扣臂43分别卡扣在雾化腔体12的侧壁上，并让雾化组件30紧固在雾化腔体12上，且雾化组件30的吸液面314经由开孔410暴露在储液空间70中。卡扣本体41的四个边框分别与雾化组件30的密封件32的四个边框对应，让雾化组件30的发热体31四周均匀受力，避免应力过大而断裂。卡扣本体41在此处还实现发热体31的加强件的功能。
图13至图18示出了本发明另一些实施例中的雾化座10a,该雾化座10a可以作为上述雾化座10的替代，其在一些实施例中可包括底座11a、纵向设置于底座11a顶部的筒状雾化腔体12a以及设置于雾化腔体12a顶部的筒状连接腔体13。底座11a在一些实施例中可用于封堵壳体20的穿孔212、为雾化组件30提供电性连接以及为雾化腔体12a导入周围环境空气。雾化腔体12a在一些实施例中可用形成雾化腔120a，并可供雾化组件30安装于其上与该雾化腔120a相连通。连接腔体13a在一些实施例中可用于将雾化腔120a与壳体20的导气管道22相连通、用于对储液空间70进行分区以及用于给储液空间70换气。
底座11a在一些实施例中可包括横截面大致呈椭圆形的底座本体111a，包括环形的第一部分1111a和沿轴向嵌置于该环形的第一部分1111a的中心通孔中的柱状第二部分1112a。第一部分1111a和第二部分1112a在一些实施例中均可采用一体注塑成型的方式制成。优选地，第二部分1112a采用较软的材料制成，以便其可以密封地嵌置于第一部分1111a中。
底座11a在一些实施例中还可包括套接于该底座本体111a的第一部分1111a上的密封圈112a、一体成型于该底座本体111a的第二部分1112a中的一对电极113a。底座本体111a以及密封圈112a一道用于封堵壳体20的穿孔212，该一对电极113a用于将雾化组件30分别与电源装置2的正负极电性连接。
一同参阅图19，电极113a在一些实施例中可采用金属片等弹性导电材料一体弯折制成，其可包括固定于底座本体111a中且部分暴露于底座本体111a的第二部分1112a底面的第一导电端1131a以及与第一导电端1131a相连且突出于第二部分1112a顶面并朝一侧倾斜的第二导电端1132a，第一导电端1131a用于与电源装置2电性连接，第二导电端1132a弹性抵压在雾化组件30上。
再如图17及图18所示，底座11在一些实施例中还可包括贯通底座本体111a的第二部分1112a上下的进气通道114a、设置于底座本体111a的第二部分1112a顶面且位于该进气通道114a的出气口附近的导流结构115a以及分别设置于底座本体111a的第一部分1111a顶面两相对端的一对卡扣臂116a。该进气通道114a用于供周围环境空气进入雾化腔120a中，该导流结构115a用于将气流导向雾化组件30。该一对卡扣臂116a用于分别与该外壳21的两个卡槽216相卡合。
进气通道114a的横截面在一些实施例中可呈长方形，从而形成纵长狭缝，其包括位于下部的进气段1141a、位于上部的出气段1143a以及将进气段1141a和出气段1143a相连通的过渡段1142a，其中，进气段1141a的横截面积大于出气段1143a的横截面积，以让吸入的气体经由出气段1143a流出时被加速，而能更好地吹向雾化组件30。导流结构115a在一些实施例中可包括位于出气段1143a的出气口正上方的导流面1151a，该导流面1151a可为朝向雾化组件30的方向倾斜的平面。可以理解地，进气通道114的横截面并不局限于长方形，其也可以呈纵长跑道型、纵长椭圆形等纵长狭缝，其也可以圆形、正方形等柱状细缝形状。
在一些实施例中，导流面1151与出气段1143纵向的夹角为90-160°，优选地为90-135°。在一些实施例中，出气段1143的缝宽优先为0.5-1.0mm。在一些实施例中，出气段1143的出气口所在平面优选地低于雾化组件30的雾化面313大致0.5-1.5mm，尽量减少气流的损失。在一些实施例中，出气段1143纵向与雾化组件30的雾化面313相平行。
可以理解地，上述出气口呈狭缝设置，且与导流结构相配合，有助提高流向雾化组件30的雾化面313的气流流速及流量，从而提高带走雾化气的效率。另外，进气通道114缝宽先宽后收窄可以改善吸阻。
雾化腔体12a在一些实施例中可呈筒状，并可沿纵向一体成型于底座本体111a的第一部分1111a的顶面。雾化腔体12a在一些实施例可包括在周向上依序连接的第一侧壁121a、第二侧壁123a、第三侧壁125a以及第四侧壁127a，这些侧壁一道界定出一个大致呈长方体状的雾化腔120a。雾化腔体12的第一侧壁121a、第二侧壁123a以及第四侧壁127a分别与外壳21的第一侧壁211、第二侧壁213和第四侧壁217相对，且均具有间隙，这些间隙相互连通。第一侧壁121a、第二侧壁123a以及第四侧壁127a在一些实施例中可均包括平坦的外表面。第三侧壁125a的外壁面可紧贴在壳体20的外壳21的第三侧壁215的内壁面上，第三侧壁125的外壁面在一些实施例中可呈弧形，以更好地与外壳21的第三侧壁215的内壁面紧贴。
雾化腔体12a的第一侧壁121a在一些实施例可包括用于收容雾化组件30的安装部1210a以及用于将该安装部1210a与雾化腔120a相连通的穿孔1212a。该安装部1210a在一些实施例中可由该第一侧壁121a的外表面朝远离外壳21的第一侧壁211a的方向凹陷而成。穿孔1212a在一些实施例中可形成于安装部1210a的槽底中部，其形状和尺寸可与雾化组件30的雾化面313的形状和尺寸相适配，电极113a的第二导电端1132a伸入到穿孔1212a中与雾化组件30弹性抵接。第二侧壁123a以及第四侧壁127a的外表面在一些实施例中可分别设置卡台122a，以与卡扣件40相卡扣。第一侧壁121的外表面在一些实施例中可为平面。
连接腔体13a在一些实施例可包括在周向上依序连接的第一侧壁131a、第二侧壁133a、第三侧壁135a以及第四侧壁137a。该第一侧壁131a、第二侧壁133a、第三侧壁135a以及第四侧壁137a一道界定出一个圆柱形的容腔130a，以供第一密封件50嵌置于其中。连接腔体13a在一些实施例中可沿纵向一体成型于雾化腔体12a的顶部，且其第三侧壁135a与雾化腔体12a的第三侧壁125a在同一个垂直面上。连接腔体13a的第一侧壁131a到第三侧壁135a的距离大于雾化腔体12a的第一侧壁121a到第三侧壁125a的距离。
该第一侧壁131a和第三侧壁135a的外壁面分别紧抵于外壳21的第一侧壁211和第二侧壁213的内表面，将储液空间70分隔出一个位于连接腔体13a下方的汇集部71以及位于连接腔体13a上方的储液仓72。汇集部71由雾化腔体12与外壳21的第一侧壁211、第二侧壁213和第四侧壁217之间的间隙形成，并呈C型围绕雾化腔体12。连接腔体13a的第二侧壁133a和第四侧壁137a分别与外壳21的第二侧壁213和第四侧壁217相对，且分别形成两个间隙，该两个间隙将汇集部71和储液仓72相连通，分别形成液体从储液仓72进入汇集部71的第一下液口73和第二下液口74。
连接腔体13a与雾化腔体12a连接处在一些实施例可设有台阶132a，该台阶的顶面形成有与雾化腔120a相连通且呈水平延伸的具有毛细作用力的第一导气槽1320a。连接腔体13a的第三侧壁135a在一些实施例中可包括形成于内表面的纵向延伸的具有毛细作用力的第二导气槽1351a，该第二导气槽1351a的下端与该第一导气槽1320a相连通。该第三侧壁135a在一些实施例中还可包括形成于外表面的纵向延伸的具有毛细作用力的第三导气槽1353a以及贯穿该第三侧壁135a以将该第三导气槽1353a与该第二导气槽1351a相连通的导气孔1352a。该第三导气槽1353a的上端与储液空间70的储液仓72相连通。第一导气槽1320a、第二导气槽1351a、导气孔1352a以及第三导气槽1353a一道形成雾化器1的换气通道，以实现储液空间70内的气液平衡。
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。
