下面参照图1-图39详细描述根据本发明实施例的集尘组件100。
如图1-图4所示，根据本发明实施例的集尘组件100，包括：第一环形圈110、第二环形圈120、绝缘间隔组件130以及导风件220。
其中，如图2所示，集尘组件100在使用过程中，可以与电源(例如高压电源500)连接，高压电源500的高电位端与第一环形圈110和第二环形圈120中的一个电连接，高压电源500的低电位端与另一个电连接。例如，在本发明的一个示例中，高电位端通过第一电连接件113与第一环形圈110电连接，低电位端通过第二电连接件123与第二环形圈120电连接。第一环形圈110、第二环形圈120与高压电源500接通后，间隔开的第一环形圈110和第二环形圈120上任意相邻的两个面之间形成高压直流电场。
需要说明的是，高压直流电场使空气中的气体分子电离，产生大量电子和离子，在电场力的作用下向两极移动，在移动过程中碰到气流中的粉尘颗粒和细菌使其荷电，荷电颗 粒在电场力作用下与气流分向相反的极板做运动。在电场作用下，空气中的自由离子要向两极移动，电压愈高、电场强度愈高，离子的运动速度愈快。由于离子的运动，极间形成了电流。开始时，空气中的自由离子少，电流较少。电压升高到一定数值后，放电极附近的离子获得了较高的能量和速度，它们撞击空气中的中性原子时，中性原子会分解成正、负离子，这种现象称为空气电离。空气电离后产生连锁反应，使得在极间运动的离子数大大增加，表现为极间的电流(称之为电晕电流)急剧增加，由此，空气成了导体，高强电压捕获附带细菌颗粒，瞬间导电击穿由蛋白质组成的细胞壁，达到杀灭细菌吸附除尘的目的。
具体而言，第一环形圈110具有第一外圈111和沿周向设在第一外圈111内表面的多个第一叶片112。在本发明的一个示例中，第一叶片112呈片状且沿第一外圈111的径向方向延伸。第二环形圈120具有第二外圈121和沿周向设在第二外圈121内表面的多个第二叶片122。如图1-图4所示，第二环形圈120设在第一环形圈110的下方，且多个第二叶片122与多个第一叶片112在周向上交错错开布置。由此，可以在第一环形圈110和第二环形圈120之间形成多个高压直流电场，由此，提高了集尘组件100的除尘效率。
另外，相邻的第一叶片112和第二叶片122之间形成气流通道，在周向上交错错开布置第一叶片112和第二叶片122对经过集尘组件100的气流具有整流的作用，增强了气流均匀性，进而降低了气流的进气压力和流动时的阻力，从而降低了气流流动时产生的噪音。
第一环形圈110具有适于与电源的正极和负极中的其中一个相连的第一电连接件113，第二环形圈120具有适于与电源的正极和负极中的另一个相连的第二电连接件123。由此，通过第一电连接件113和第二电连接件123可以保证第一环形圈110和第二环形圈120与高压电源500可靠连接。当集尘组件100与高压电源500接通后，流经第一环形圈110和第二环形圈120之间的气流内的灰尘、颗粒物等将会被高压直流电场捕捉，并被吸附到第一环形圈110或第二环形圈120的表面，从而达到了除尘的目的。
绝缘间隔组件130设在第一环形圈110和第二环形圈120之间且使第一环形圈110和第二环形圈120间隔开布置。换言之，绝缘间隔组件130支撑在第一环形圈110和第二环形圈120之间，以使第一环形圈110上的任意一个点均与第二环形圈120不直接接触。由此，可以保证集尘组件100在使用过程中，第一环形圈110上与第二环形圈120的相邻的面之间形成高压电场，进而实现集尘组件100的集尘杀菌的效果。根据本发明的一个实施例，绝缘间隔组件130与第一环形圈110和第二环形圈120均为可拆卸的连接，由此，当集尘组件100需要清洗时，方便用户擦拭、清洗集尘组件100。
由此，通过使多个第二叶片122与多个第一叶片112在周向上交错错开布置，可以使第一环形圈110和第二环形圈120之间形成多个高压直流电场，提高了集尘组件100的除 尘效率。另外，多个第一叶片112和多个第二叶片122对经过集尘组件100的气流具有整流的作用，由此增强了气流均匀性，进而降低了气流的进气压力和流动时的阻力，从而降低了气流流动时产生的噪音。
导风件220形成为环形且套设在第一环形圈110和/或第二环形圈120的外部，导风件220的上端的外径大于其下端外径。由此，可将气流引导至第一环形圈110和第二环形圈120所在的位置处，从而提高了集尘组件100的除尘效率。另外，导风件220与第一环形圈110和/或第二环形圈120通过卡扣连接，由此可简化集尘组件100的装配过程，提高了装配效率。
根据本发明实施例的集尘组件100，通过将导风件220设在第一环形圈110和/或第二环形圈120的外部，由此可将气流引导至第一环形圈110和第二环形圈120处，进而提高了集尘组件100的除尘效率。同时，使导风件220与第一环形圈110和/或第二环形圈120卡接，简化了装配过程，提高了装配效率。
同时，使多个第二叶片122和多个第一叶片112在周向上交错错开布置，不但可以使第一环形圈110和第二环形圈120之间形成多个高压直流电场，还可增大高压直流电场的有效面积，进而提高了集尘组件100的除尘效率。另外，多个第一叶片112和多个第二叶片122对经过集尘组件100的气流具有整流的作用，由此增强了气流均匀性，进而降低了气流的进气压力和流动时的阻力，从而降低了气流流动时产生的噪音。
在本发明的一个示例中，如图3-图4所示，导风件220与第二外圈121连接。由此，便于导风件220与第二环形圈120连接。在图30-图34所示的示例中，导风件220上具有导风件卡勾223，第二外圈121向外延伸出外圈连接端子128，外圈连接端子128上具有与导风件卡勾223配合的台阶面1281。通过使导风件卡勾223与台阶面1281相抵，以限定外圈连接端子128在上下方向(如图34所示的上下方向)上的位移。
如图11、图34所示，外圈连接端子128具有沿上下方向(如图11所示的上下方向)贯通其的缺口部1282，缺口部1282的内壁上设有先向下延伸再向上弯折的弯折板1283，其中台阶面1281设在弯折板1283的外侧表面上。可以理解的是，在第二外圈121的径向方向上，弯折板1283具有弹性，导风件卡勾223包括沿导风件220轴向方向向上延伸的板体2231和位于板体2231上端且朝向弯折板1283凸出的卡勾凸起2232。装配时，可以将外圈连接端子128由上向下安装，台阶面1281的下部先与导风件卡勾223的卡勾凸起2232相抵，弯折板1283先朝向第二外圈121径向向内的方向发生形变，当台阶面1281与卡勾凸起2232的下端面相抵时，弯折板1283再朝向第二外圈121径向向外的方向复原。此时，卡勾凸起2232与弯折板1283卡接连接。由此，简化了导风件220与第二环形圈120的装配过程，提高了导风件220与第二环形圈120的连接可靠性。
进一步地，如图4所示，导风件220上还具有向上延伸出的第一延伸板224，第一延伸板224配合在缺口部1282内且与弯折板1283间隔开，以限制外圈连接端子128在导风件220周向方向上的移动。更进一步地，如图4和图32所示，导风件220上还具有向上延伸出的第二延伸板225，第二延伸板225与第一延伸板224共同限定出容纳外圈连接端子128的外端的容纳槽226。由此，可以进一步提高外圈连接端子128与导风件220之间的连接可靠性。
根据本发明的一些实施例，如图4所示，导风件220可以包括：第一导风圈221和第二导风圈222。具体地，第一导风圈221沿径向从内到外逐渐沿弧形向上延伸。例如，在如图4所示的示例中，第一导风圈221的内径尺寸由下至上(如图4所示的上下方向)依次增大。第二导风圈222连接在第一导风圈221的下端，第二导风圈222的上表面位于同一平面内。第二环形圈120的至少部分位于第一导风圈221内，第二环形圈120与第二导风圈222卡接。由此，可以将更多的气流引导至集尘组件100内，进而提高了集尘组件100的工作效率。
根据本发明的一个实施例，第一环形圈110和第二环形圈120之间的最短距离大于等于2mm。换言之，第一环形圈110上任意一点与第二环形圈120之间距离大于等于2mm。由此，可以有效地防止集尘组件100在使用过程中发生空气被击穿、放电或短路的现象，从而提高了集尘组件100的工作稳定性，保证了集尘组件100的安全系数和除尘效果。根据本发明的一个实施例，相邻的第一叶片112和第二叶片122间隔的距离为2-40mm。由此，可以进一步防止集尘组件100在使用过程中发生空气被击穿、放电的现象，从而进一步地提高了集尘组件100的工作稳定性，保证了集尘组件100的安全系数和除尘效果。同时，也可以避免手指因误伸入到第一叶片112和第二叶片122之间而造成伤害。
在本发明的一个示例中，如图6所示，第一叶片112沿第一环形圈110周向方向上的厚度为大于0.5mm，即d1＞0.5mm。如图8所示，第一叶片112沿第一环形圈110的轴向方向上的宽度大于5mm，即h1＞5mm。如图12所示，第二叶片122沿第二环形圈120的周向方向上的厚度大于0.5mm，即d2＞0.5mm。如图14所示，第二叶片122沿第二环形圈120的轴向方向上的宽度大于5mm，即h2＞5mm。由此，可以保证集尘组件100的净化效果，提高集尘组件100的净化效率，简化集尘组件100的结构，使得集尘组件100的结构更加紧凑、合理。
考虑到第一环形圈110位于第二环形圈120的上方，为保证第一外圈111与第二环形圈120间隔排布，在如图5所示的示例中，第一外圈111连接在第一叶片112的上端(如图5所示的上下方向)，由此，可以使集尘组件100的结构更加紧凑、合理。
进一步地，如图5、图6、图8以及图10所示，第一外圈111连接在第一叶片112的 径向外侧的上端，第一叶片112的径向外侧的上表面高于其径向内侧的上表面。换言之，在第一环形圈110的轴向方向上，第一叶片112的径向外侧的宽度大于其径向内侧的宽度。由此，进一步提高了集尘组件100的紧凑程度。更进一步地，如图5和图7所示，多个第一叶片112的下表面均平齐且位于同一平面上。
在如图5-图10所示的示例中，第一环形圈110还可以包括：第一内圈114。其中，第一内圈114连接在多个第一叶片112的径向内侧。由此，可以使第一环形圈110的结构更加稳定。进一步地，如图5-图6所示，第一环形圈110还包括：第一加强圈115。其中，第一加强圈115通过多个沿周向分布的第一加强筋116连接在第一内圈114的内表面上。由此，可以进一步加强第一环形圈110的结构强度。
同样地，在如图11-图15所示的示例中，第二叶片122的径向外侧的下表面高于其径向内侧的下表面。换言之，在第二环形圈120的轴向方向上，第二叶片122的径向外侧的宽度大于其径向内侧的宽度。第二外圈121连接在第二叶片122的径向外侧。当第二环形圈120与第一环形圈110配合时，可以进一步增大相邻的第一叶片112与第二叶片122相对应的面积，进而增大了相邻的第一叶片112与第二叶片122间形成的高压直流电场的面积，由此，可以提高集尘组件100的除尘效率。同时，也可以进一步提高集尘组件100的紧凑程度。更进一步地，如图5和图7所示，多个第二叶片122的上表面均平齐且位于同一平面上。
在如图11-图15所示的示例中，第二环形圈120还可以包括：第二内圈124。其中，第二内圈124连接在多个第二叶片122的径向内侧的下端。由此，可以使第二环形圈120的结构更加稳定。进一步地，如图11-图15所示，第二环形圈120还可以包括：第二加强圈125。其中，第二加强圈125通过多个沿周向分布的第二加强筋126连接在第二内圈124的内表面上。由此，可以进一步加强第二环形圈120的结构强度。
如图4、图17-图27所示，根据本发明的一个实施例，绝缘间隔组件130包括：至少一个第一绝缘卡扣131。其中，第一绝缘卡扣131安装在第一外圈111和第二外圈121上以将第一外圈111和第二外圈121间隔开地相连。由此，可以使第一环形圈110上任意一点与第二环形圈120之间保持一定距离，进而使集尘组件100在工作状态下，第一环形圈110和第二环形圈120之间的空气不被击穿、不发生放电的现象，从而保证了集尘组件100的稳定性和安全性。此外，利用第一绝缘卡扣131将第一外圈111和第二外圈121间隔开地相连，简化了集尘组件100的装配过程，提高了装配效率，降低了生产成本。
在如图11-图13所示的示例中，第二外圈121的周壁上设有定位柱1211，以便于第一绝缘卡扣131与第二外圈121连接。另外，如图22-图26所示，第一绝缘卡扣131包括：第一本体1311、至少两只第一卡合脚1312以及第一卡勾1313。其中，在上下方向上，第 一本体1311具有大于等于2mm的高度，由此，可以保证第一外圈111和第二外圈121之间具有大于等于2mm的距离，以防止第一外圈111和第二外圈121之间发生空气被击穿、放电的现象。
在如图11、图17-图27所示的示例中，至少两只第一卡合脚1312从第一本体1311的下端向下延伸且套设在定位柱1211外以将第一本体1311与第二外圈121连接。如图26所示，每个第一卡合脚1312与定位柱1211的下端面相抵，以将定位柱1211限定在至少两只第一卡合脚1312之间。为方便第一绝缘卡扣131与第一外圈111连接，第一卡勾1313从第一本体1311的上端向上延伸且与第一外圈111的边缘扣合以将第一本体1311与第一外圈111连接。
如图23、图25以及图27所示，第一本体1311具有沿上下方向贯通第一本体1311的通孔1315。换言之，第一本体1311可以形成为筒状，由此，在保证第一绝缘卡扣131的结构强度的条件下，可以进一步地简化第一绝缘卡扣131的结构，减轻第一绝缘卡扣131的质量，降低了生产成本。
如图23所示，在本发明的一个实施例中，第一本体1311的上端面包括：第一段1316、第二段1317以及连接段1318。其中，第一段1316位于远离第一卡勾1313的一侧，且第一段1316位于一水平面内。第二段1317设在靠近第一卡勾1313的一侧，且第二段1317位于第一段1316的下方的另一水平面内。连接段1318连接在第一段1316和第二段1317之间。换言之，连接段1318上与第一卡勾1313之间的距离由下至上逐渐增大。由此，第一卡勾1313在与其他部件相连时，连接段1318可以起到导引的作用，便于第一绝缘卡扣131与其他部件相连，进而提高了第一绝缘卡扣131的装配效率。
如图23和图24所示，第一绝缘卡扣131可以由具有绝缘特性的材料制成，由此第一绝缘卡扣131连接的两个部件之间不导电，由此，可以满足不同部件之间的使用需求。为提高第一绝缘卡扣131的结构强度，第一本体1311与第一卡合脚1312之间连接有加强肋1314。在如图24所示的示例中，加强肋1314可以为多个，加强肋1314间隔地分布在第一本体1311的外周壁上。在本发明的一个示例中，加强肋1314为三角形加强肋，三角形加强肋的第一侧边与第一本体1311相连，三角形加强肋的第二侧边与第一卡合脚1312相连。
为进一步提高第一绝缘卡扣131与第二环形圈120之间的连接强度，在如图21所示的示例中，定位柱1211设在第二外圈121和其中一个第二叶片122的相交处。
更进一步地，如图22所示，第一本体1311上远离第一外圈111的中心的外侧表面形成为弧形面，第一卡合脚1312包括三个，其中一个第一卡合脚1312卡合至第二外圈121的外侧且其外表面与弧形面平齐。由此，可以提高第一绝缘卡扣131的结构强度，使第一绝缘卡扣131的结构更加合理。
根据本发明的一个实施例，如图5、图6以及图9所示，第一环形圈110进一步包括第一连接端子117，第一连接端子117设在第一外圈111的径向外侧。如图11-图12所示，第二环形圈120进一步包括第二连接端子127，第二连接端子127设在第二外圈121的径向外侧且与第一连接端子117上下对应。为方便第一环形圈110、第二环形圈120与高压电源500连接，第一电连接件113设在第一连接端子117上，第二电连接件123设在第二连接端子127上。进一步地，为了防止第一连接端子117与第二连接端子127接触，如图28-图29所示，绝缘间隔组件130还包括第二绝缘卡扣132，第二绝缘卡扣132设在第一连接端子117和第二连接端子127之间。
在如图5-图6、图11-图12以及图28-图29所示的示例中，为方便第二绝缘卡扣132与第一连接端子117和第二连接端子127相连，第一连接端子117具有第一卡合孔1171且在第一连接端子117的下表面上向下延伸出弹性卡扣1172，第二连接端子127上具有第二卡合孔1271。第二绝缘卡扣132包括：第二本体1321、第二卡勾1323以及凸台1324。其中，第二本体1321具有大于等于2mm的高度，由此，可以保证第一连接端子117和第二连接端子127之间具有大于等于2mm的距离，以防止第一连接端子117和第二连接端子127之间发生空气被击穿、放电的现象。
如图28所示，第二本体1321的内部中空，第二本体1321的顶部具有开口且底部敞开，弹性卡扣1172穿过开口伸入并卡合在第二本体1321内。凸台1324从第二本体1321的顶部向上延伸出且穿过第一卡合孔1171。由此，可以保证第二绝缘卡扣132与第一连接端子117可靠连接。如图28所示，在本发明的一个的示例中，凸台1324在上下方向上的横截面呈长方形，且凸台1324在上下方向上的横截面积由上至下逐渐增大。由此，便于凸台1324与其他部件配合。
如图28、图29所示，第二本体1321的外表面上相对两侧向外延伸出第二卡合脚1322，第二卡合脚1322与第二连接端子127的上表面止抵。第二卡勾1323从第二本体1321的位于两个第二卡合脚1322之间的侧壁向下伸出以穿过第二卡合孔1271后卡合至第二连接端子127的底面,第二卡勾1323与第二连接端子127的下表面止抵。通过将第二卡合脚1322和第二卡勾1323卡接在第二卡合孔1271内，可以限定第二绝缘卡扣132沿第二卡合孔1271的周向方向上的运动；在通过使第二卡合脚1322与第二连接端子127的上表面止抵、使第二卡勾1323与第二连接端子127的下表面止抵，可以限定第二绝缘卡扣132沿第二卡合孔1271的轴向方向上的运动。由此，可以保证第二绝缘卡扣132与第二连接端子127的可靠连接。
如图28所示，在本发明的一个实施例中，第二本体1321在上下方向上的横截面的形状为方形。由此，可以提高第二绝缘卡扣132的结构强度，也可以使第二绝缘卡扣132的 结构更加紧凑、合理。
在如图28所示的示例中，开口1325的侧壁与第二本体1321的上端面之间形成引导弧面1326。由此，引导弧面1326具有引导的作用，以便于其他部件与第二绝缘卡扣132的配合连接。对于开口1325的形状不做具体限制，例如，在本发明的一个的示例中，如图28所示，开口1325可以形成为方形孔。
进一步地，如图28所示，第二卡合脚1322设置在邻近第二本体1321的侧壁下端的位置处，位于第二卡合脚1322下方的第二本体1321的侧壁形成为引导部1327，引导部1327在上下方向上的横截面积由上至下逐渐减小。由此，可以通过引导部1327引导第二卡合脚1322与其他部件配合，进而可以提高第二绝缘卡扣132与其他部件之间的装配效率。
更进一步地，如图28所示，第二卡勾1323的下端面与第二卡勾1323的侧壁之间具有引导斜面1328。由此，便于第二卡勾1323与其他部件配合，进而提高了第二绝缘卡扣132的装配效率。
为方便将第一环形圈110装配至第二环形圈120上，在如图1-图4所示的示例中，第一外圈111的外径小于等于第二外圈121的外径。
另外，在本发明的一个实施例中，第一环形圈110和第二环形圈120中至少一个为高内阻环形圈，高内阻环形圈的表面电阻率为10的6次方至10的12次方，即高内阻环形圈的表面电阻率为106-1012欧姆·米。例如，当第一环形圈110为高内阻环形圈时，第二环形圈120可以为铝或者铜等低内阻材料制成的环形圈，为提高集尘组件100的安全性能，第二环形圈120与低电位端相连，此时，人体即使触摸集尘组件100，采用低内阻材料制成的第二环形圈由于是与低电位端连接，流经人体的电流还是被限制在安全的范围内，不会对人体健康造成影响；当第一环形圈110和第二环形圈120均采用可导电的高内阻材料制成时，高内阻材料可以将第一环形圈110和第二环形圈120上的电流限定在安全范围内，人体在触摸集尘组件100后，对人身安全不会造成危害，由此提高了集尘组件100的安全性。由此，便于在相邻的第一叶片112和第二叶片122导叶之间形成至少2000V以上的直流高压电场，进而可以保证集尘组件100的除尘效率和除尘效果。
根据本发明的一个实施例，第一环形圈110具有第一外圈111和沿周向设在第一外圈111内表面的多个第一叶片112。第一叶片112包括第一叶片本体1121和凸出于第一叶片本体1121的一个侧边的第一叶片抬高部1122，第一叶片抬高部1122的侧面与第一叶片本体1121的侧面平齐。换言之，第一叶片本体1121与第一叶片抬高部1122在同一平面内延伸。第一叶片抬高部1122与第一外圈111连接。
第二环形圈120具有第二外圈121和沿周向设在第二外圈121内表面的多个第二叶片122。第二叶片122包括第二叶片本体1221和凸出于第二叶片本体1221的一个侧边的第二 叶片抬高部1222，第二叶片抬高部1222的侧面与第二叶片本体1221的侧面平齐。换言之，第二叶片本体1221与第二叶片抬高部1222在同一平面内延伸。第二叶片抬高部1222与第二外圈121连接。如图1-图4所示，第二环形圈120设在第一环形圈110的下方，且多个第二叶片122与多个第一叶片112在周向上交错错开布置。由此，可以在第一环形圈110和第二环形圈120之间形成多个高压直流电场，由此，提高了集尘组件100的除尘效率。通过使多个第二叶片122与多个第一叶片112在周向上交错错开布置，可以增加高压直流电场的有效面积，进而提高了集尘组件100的除尘效率。
在本发明的一个示例中，如图6所示，第一叶片本体1121沿第一环形圈110周向方向上的厚度大于0.5mm，即d1＞0.5mm。根据本发明的一个实施例，d1＝1.5mm。如图8所示，第一叶片本体1121沿第一环形圈110的轴向方向上的宽度大于5mm。根据本发明的一个实施例，第一叶片本体1121沿第一环形圈110的轴向方向上的宽度为36mm。如图12所示，第二叶片本体1221沿第二环形圈120的周向方向上的厚度大于0.5mm，即d2＞0.5mm。根据本发明的一个实施例，d2＝1.5mm。如图14所示，第二叶片本体1221沿第二环形圈120的轴向方向上的宽度大于5mm。根据本发明的一个实施例，第二叶片本体1221沿第二环形圈120的轴向方向上的宽度为36mm。由此，可以简化集尘组件100的结构，使得集尘组件100的结构更加紧凑、合理。同时，也可以避免手指因误伸入到第一叶片112和第二叶片122之间而造成伤害。
考虑到第一环形圈110位于第二环形圈120的上方，为保证第一外圈111与第二环形圈120间隔排布，在如图5所示的示例中，第一外圈111连接在第一叶片112的上端(如图5所示的上下方向)，由此，可以使集尘组件100的结构更加紧凑、合理。
在如图38所示的示例中，第一环形圈110的周向方向上，第一叶片112的厚度由径向内侧至径向外侧依次增大，第二叶片121的厚度由径向内侧至径向外侧的方向上依次增大。由此，可以增大第一叶片112上与第二叶片122相对应的面积，进而可以使相邻的第一叶片112和第二叶片122之间形成有效的高压直流电场，进而可以改善集尘组件100的除尘效果，提高集尘组件100的除尘效率。
根据本发明的一个实施例，如图8和图14所示，第一叶片抬高部1122设在邻近第一叶片本体1121上的相邻的两个侧边的交点处，第二叶片抬高部1222设在邻近第二叶片本体1221的相邻的两个侧边的交点处。由此，可以进一步增大第一叶片112上与第二叶片122相对应的面积，进而可以使相邻的第一叶片112和第二叶片122之间形成有效的高压直流电场，进而可以改善集尘组件100的除尘效果，提高集尘组件100的除尘效率。
在如图4所示的示例中，第一叶片112和第二叶片122均可以形成为平板状，第一叶片112和第二叶片122均为多边形、椭圆形或圆形。根据本发明的一个实施例，第一叶片 112和第二叶片122均形成为矩形。由此，可使集尘组件100的结构更加紧凑、合理。进一步地，矩形板状的第一叶片上相邻的两个侧边之间圆滑过渡，由此，可以避免尖端放电，进而提高了集尘组件100的安全性。
可以理解的是，第一叶片112和第二叶片122的形状并不限于此，例如，在如图26所示的示例中，第一叶片112和第二叶片122均形成为弯折板状，且在垂直于第一环形圈110的轴线方向上，第一叶片112的横截面的形状与第二叶片122的横截面形状对应。由此，可以进一步增加第一叶片112上与第二叶片122对应的面积，进而提高了第一叶片112和第二叶片122上可以形成电场的面积，从而提高了集尘组件100的除尘效率。
再如，在图37所示的示例中，在垂直于第一环形圈110的轴线方向上，第一叶片112和第二叶片122的横截面均形成为曲线形，且第一叶片112与对应的第二叶片122具有相同的曲率半径。具有曲线形横截面的第一叶片112和第二叶片122还具有导流的作用。进一步地，在如图37所示的示例中，第一叶片112和第二叶片122的横截面均形成为圆弧形。
如图4所示，第一叶片112沿所述第一环形圈110的径向方向延伸；所述第二叶片122沿所述第二环形圈120的径向方向延伸。由此，可使集尘组件100的结构更加紧凑、合理。当然，第一叶片112和第二叶片122的延伸方向并不限于此，例如，在如图38-39所示的示例中，第一叶片112沿倾斜于所述第一环形圈110径向方向的方向延伸；所述第二叶片122沿倾斜于所述第二环形圈120径向方向的方向延伸。
根据本发明的一个的实施例，第一环形圈110上的任意两个相邻的面之间圆滑过渡，所述第二环形圈120上的任意两个相邻的面之间圆滑过渡。由此，可以有效地避免尖端放电，从而提高了集尘组件100的安全性。
根据本发明实施例的空气净化装置，包括：如上所述的集尘组件100。
根据本发明实施例的空气净化装置，通过设置如上所述的集尘组件100，将导风件220设在第一环形圈110和/或第二环形圈120的外部，由此可将气流引导至第一环形圈110和第二环形圈120处，进而提高了集尘组件100的除尘效率。同时，使导风件220与第一环形圈110和/或第二环形圈120卡接，简化了装配过程，提高了装配效率。
同时，使多个第二叶片122和多个第一叶片112在周向上交错错开布置，不但可以使第一环形圈110和第二环形圈120之间形成多个高压直流电场，还可增大高压直流电场的有效面积，进而提高了集尘组件100的除尘效率。另外，多个第一叶片112和多个第二叶片122对经过集尘组件100的气流具有整流的作用，由此增强了气流均匀性，进而降低了气流的进气压力和流动时的阻力，从而降低了气流流动时产生的噪音。
根据本发明的一些实施例，如图4所示，导风件220包括：第一导风圈221和第二导 风圈222。具体地，第一导风圈221沿径向从内到外逐渐沿弧形向上延伸。例如，在如图4所示的示例中，第一导风圈221的内径尺寸由下至上(如图4所示的上下方向)依次增大。第二导风圈222连接在第一导风圈221的下端，第二导风圈222的上表面位于同一平面内。集尘组件100至少部分位于第一导风圈221内，集尘组件100与第二导风圈222连接。由此，可以将更多的气流引导至集尘组件100内，进而提高了空气净化装置的工作效率。在本发明的一个示例中，如图3-图4所示，导风件220与集尘组件100的第二外圈121连接。
在图30-图34所示的示例中，导风件220上具有第三卡勾223，第二外圈121向外延伸出外圈连接端子128，外圈连接端子128上具有与第三卡勾223配合的台阶面1281。通过使第三卡勾223与台阶面1281相抵，以限定外圈连接端子128在上下方向(如图34所示的上下方向)上的移动。
如图11所示，外圈连接端子128具有沿上下方向(如图11所示的上下方向)贯通其的缺口部1282，缺口部1282的内壁上设有先向下延伸再向上弯折的弯折板1283，其中台阶面1281设在弯折板1283的外侧表面上。可以理解的是，在第二外圈121的径向方向上，弯折板1283具有弹性，第三卡勾223包括沿导风件220轴向方向向上延伸的板体2231和位于板体2231上端且朝向弯折板1283凸出的卡勾凸起2232。装配时，可以将外圈连接端子128由上向下安装，台阶面1281的下部先与第三卡勾223的卡勾凸起2232相抵，弯折板1283先朝向第二外圈121径向向内的方向发生形变，当台阶面1281与卡勾凸起2232的下端面相抵时，弯折板1283再朝向第二外圈121径向向外的方向复原。此时，卡勾凸起2232与弯折板1283卡接连接。由此，简化了导风件220与集尘组件100的装配过程，提高了导风件220与集尘组件100的连接可靠性。
进一步地，如图4所示，导风件220上还具有向上延伸出的第一延伸板224，第一延伸板224配合在缺口部1282内且与弯折板1283间隔开，以限制外圈连接端子128在导风件220周向方向上的移动。更进一步地，如图4和图32所示，导风件220上还具有向上延伸出的第二延伸板225，第二延伸板225与第一延伸板224共同限定出容纳外圈连接端子128的外端的容纳槽226。由此，可以进一步提高外圈连接端子128与导风件220之间的连接可靠性。
根据本发明实施例的空调器(图未示出)，包括：壳体和上述的集尘组件100。具体而言，壳体具有风道，以对流经空调器的气流的路径进行限定。可以理解的是，对于风道的位置不做具体限定，例如，风道可以位于壳体内。风道具有进风口和出风口，气流由进风口进入到风道内，并由出风口排出到风道外。集尘组件100设在风道内，以对进入到风道内的气流进行净化除尘。考虑到集尘组件100需要定期清洗，为方便用户对集尘组件100 进行清洗，集尘组件100设在邻近进风口或出风口的位置处。根据本发明的一个实施例，集尘组件100设在邻近进风口的位置处。由此，可以对进入到风道内的气流先进行净化除尘，以防止尘埃等颗粒物堆积在风道内部，不便于用户清洗。
根据本发明实施例的空调器，通过设置如上所述的集尘组件100，将导风件220设在第一环形圈110和/或第二环形圈120的外部，由此可将气流引导至第一环形圈110和第二环形圈120处，进而提高了集尘组件100的除尘效率。同时，使导风件220与第一环形圈110和/或第二环形圈120卡接，简化了装配过程，提高了装配效率。
同时，使多个第二叶片122和多个第一叶片112在周向上交错错开布置，不但可以使第一环形圈110和第二环形圈120之间形成多个高压直流电场，还可增大高压直流电场的有效面积，进而提高了集尘组件100的除尘效率。另外，多个第一叶片112和多个第二叶片122对经过集尘组件100的气流具有整流的作用，由此增强了气流均匀性，进而降低了气流的进气压力和流动时的阻力，从而降低了气流流动时产生的噪音。
为进一步提高空调器的净化效率，空调器还可以包括负离子发射电离装置(图未示出)，在风道内的气流流动方向上，负离子发射电离装置位于风道内，以对气流预充负电，进而可使气流中大部件尘埃颗粒物带负电。带负电的尘埃颗粒物体随气流流经空调器时迅速被高压直流电场捕获，由此进一步提升了除尘效果。
