具体实施方式
在一相关技术中，空气净化装置的甩水组件包括甩水套筒和传动轴，其中，甩水套筒包括上盖、上套筒结构和下套筒结构三部分，在上套筒结构上设置有甩水孔。在使用过程中，利用传动轴带动甩水套筒高速转动以产生负压，从而将水箱内的水抽吸至甩水套筒内并由甩水孔甩出形成水幕。甩水套筒的结构复杂，零件较多，从而影响空气净化装置的装配效率，提高生产成本。要对水箱内的水提供足够的吸力，需要甩水套筒高速转动，复杂 的结构容易造成甩水套筒的转动卡滞以及转动过程中出现异响。另外，由于甩水孔设置在上套筒结构上，数量有限，对空气的加湿和净化效率较低。
针对上述问题，本申请实施例提供了一种空气净化装置，将甩水叶片的材料设置为亲水和/或吸水材料，利用甩水叶片的转动将水箱内的水扬起，同时甩水叶片吸收水箱内的水并依靠自身材料的亲/吸水特性使得整个甩水叶片湿润，转动时可将其吸收的水由甩水孔甩出，两者结合实现对进入水箱内的空气的加湿和净化，结构简单，装配效率高，成本低。
下面参考附图描述本申请实施例的空气净化装置。
参阅图1，图1为本申请实施例的空气净化装置的剖视图。如图1所示，本申请实施例提供的空气净化装置包括水箱10、风机(图中未示出)、电机和甩水结构30。其中，水箱10上设置有进风口和出风口，风机用于驱动气流经进风口进入并由出风口排出，以在进风口和出风口之间形成水箱10内的气体流路。电机用于驱动水箱10内的甩水结构30转动，从而将水箱10内的水扬起形成水幕，利用水幕对进入水箱10的空气进行过滤和加湿，使得空气中的灰尘、细菌、病毒等溶于水或者被甩水结构30形成的水分子、负离子去除，从而完成对空气的水洗净化。
甩水结构30包括中轴部31和与中轴部31的外侧面相连的甩水叶片32，中轴部31与电机的电机轴相连，从而利用电机驱动中轴部31及甩水叶片32转动。甩水叶片32上设置有多个甩水孔，甩水叶片32的材料包括亲水材料和/或吸水材料，即甩水叶片32的材料可以为亲水材料，也可以为吸水材料，还可以既有亲水材料又有吸水材料。如此，利用甩水叶片32的亲/吸水性吸收水箱10内的水以使得整个甩水叶片32湿润。可以理解的是，此处所述的“亲水性”指带有极性基团的分子，对水由较大的亲和能力，可以吸引水分子，亲水材料例如可以为ABS塑料、PPO(聚苯醚)、PS(聚苯乙烯)等。此处所述的“吸水性”指的是在水中能够吸收水分的性质，吸水材料例如可以为PET(Polyethylene terephthalate)、尼龙等。
上述空气净化装置中，将甩水结构30中的甩水叶片32设置为亲水和/或吸水材料，电机驱动甩水结构30转动时，一方面，甩水叶片32的转动能够将水箱10内的水扬起，另一方面，甩水叶片32能够吸收水箱10内的水并通过转动将其吸收的水由甩水孔甩出，两者结合来实现对进入水箱10内的空气的加湿和净化，结构简单，能够有效提高装配效率，降低生产成本。由于甩水叶片32具有亲/吸水性，水箱10内的水位可以设置的较低，依靠甩水叶片32的亲/吸水性即可使得整个甩水叶片32湿润，避免水资源的浪费。另外，由于减少了零件数量，甩水结构30转动时不容易产生异响，且不会发生卡顿问题。
水箱10的进风口和出风口可以设置在水箱10的任意位置，能够使得风机在进风口与 出风口之间形成的气流流路流经甩水结构30甩出的水幕即可。在一个示例性的实施例中，进风口设置在水箱10的侧部，出风口设置在水箱10的顶部，图2为空气净化装置的风路图，如图2所示，上述的进风口和出风口设置位置形成侧部进风、顶部出风的气流流路。相适应地，甩水结构30的中轴部31的轴线沿竖向延伸，即沿上下方向延伸。如此，在水箱10的下部，气流的流路大致呈水平方向或者与水平方向呈一定的小角度，而在水箱10的上部，气流的流路大致呈竖直方向或者与竖直方向呈一定的小角度。
甩水叶片32上的甩水孔的尺寸可以均相同，也可以设置为不同。在水箱10侧部设置进风口、顶部设置出风口的实施例中，如图2所示，由于冲击到甩水叶片32下部位置的气流大致呈水平方向，而冲击到甩水叶片32上部位置的气流大致呈竖直方向，基于此，位于甩水叶片32的下部的甩水孔的孔径可以大于位于甩水叶片32的上部的甩水孔的孔径，如此，使得冲击到甩水叶片32下部的气流尽量多地穿过甩水孔以带动甩水孔甩出的水分，而甩水叶片32上部孔径较小的甩水孔则将水分更多地甩出形成更加细密的水幕，以利用该细密的水幕对大致竖向运动的气流进行更好的加湿和净化。
甩水孔的孔径也可以是由下至上逐渐增大，也可以是将甩水叶片32分为上下两部分，位于上半部分的甩水孔的孔径相同，位于下半部分的甩水孔的孔径也相同，只是将上半部分的甩水孔孔径设置为小于下半部分的甩水孔孔径。
其中，甩水叶片32的数量可以为一片，也可以为多片。为了提高对空气的加湿和净化效率，甩水叶片32可以设置有多个，多个甩水叶片32沿中轴部31的周向均匀布置。例如，图3是本申请实施例提供的空气净化装置的甩水结构示意图，在图3所示的实施例中，甩水叶片32设置有三个。当然，可以理解的是，甩水叶片32的数量也可以为两个、四个及以上。
由于本申请实施例中是利用甩水叶片32自身的亲/吸水性来吸收水箱10内的水，因此甩水孔的设置位置不受限制，其可以设置在甩水叶片32的任意位置。即，甩水孔的设置位置、排布方式和数量均不限。为了提高对空气的加湿和净化效率，甩水孔可以布满设置在整个甩水叶片32上。在一个示例性的实施例中，如图1和图3所示，甩水叶片32包括叶片主体部321，叶片主体部321与中轴部31相连，甩水孔包括设置在叶片主体部321上的多个第一甩水孔3211，多个第一甩水孔3211在叶片主体部321上呈阵列排布，即，在叶片主体部321上设置有阵列分布的多排和多列第一甩水孔3211。
叶片主体部321可以设置为任意形状，例如设置为矩形板状结构、三角板状结构等等。为了提高叶片主体部321在转动过程中的扬水效果，如图3所示，叶片主体部321的横截面呈弯曲形，且各个甩水叶片32的叶片主体部321的弯曲方向相同，从而能够在各个甩 水叶片32同步转动时更好地将水箱10内的水扬起，进一步提高对空气的加湿和过滤效果。此处所述的横截面指的是水平面在叶片主体部321上截得的面。该弯曲形可以为圆弧形，也可以为由多段曲率半径不同的圆弧形平滑连接而成，还可以是曲率半径不断变化的形状。为了降低甩水叶片32的转动阻力，由中轴部31的径向内侧向径向外侧的方向，叶片主体部321的横截面形成的弯曲形的曲率半径可以逐渐增大。
为了方便加工，叶片主体部321可以设置为上下尺寸一致。由于甩水叶片32主要通过下部的结构进行吸水，为了给水分的上升提供更大的升力，优选地，叶片主体部321设置为下部尺寸大于上部尺寸的结构，这样，叶片主体部321能够有更多的结构与水箱10内的水直接接触，从而使得水箱10内的水能够更加快速地运送至叶片主体部321的各个位置。
为了获得更大的甩水范围，位于同一高度的各个第一甩水孔3211的轴线之间具有夹角，即，在一个甩水叶片32的叶片主体部321中，位于同一排的各个第一甩水孔3211的轴线均不平行。这样，在同一高度中，第一甩水孔3211的朝向均不相同，从而使得各个第一甩水孔3211的甩水方向各不相同，如此，能够提高该高度位置的甩水覆盖区域。而各个高度的第一甩水孔3211均设置为轴线之间具有夹角，从而提高了该叶片主体部321的整体甩水范围，且保证了叶片主体部321的甩水均匀性。
在图3所示的实施例中，甩水叶片32仅包括叶片主体部321。可以理解的是，甩水叶片32还可以包括其他部分。例如，在水箱10侧部设置进风口、顶部设置出风口的实施例中，由于气流到达甩水叶片32上部时的流动方向大致呈竖向，为了进一步提高对到达该区域的气流的净化和加湿效果，图4是本发明另一实施例的空气净化装置中甩水结构的俯视图，如图4所示，甩水叶片32还可以包括由叶片主体部321的顶部沿圆周方向延伸设置的第一延伸板部322，多个甩水孔还包括设置于第一延伸板部322上的第二甩水孔3221。由于在第一延伸部322区域的气流大致呈竖向，使得气流能够更多地穿过第一延伸板部322上的第二甩水孔3221进行净化和加湿，从而进一步提高空气净化装置的空气净化和加湿效率。
为了避免第一延伸板部322的设置对气流形成阻挡而影响空气净化装置的出风量，第一延伸板部322可以设置为螺旋叶片状，如此，在甩水叶片32转动时，第一延伸板部322可以为气流的流动提供升力，从而保证空气净化装置的出风量。示例性地，风机可以包括设置于水箱10顶部的轴流风机，第一延伸板部322的螺旋方向与轴流风机的叶片的螺旋方向相同，如此，第一延伸板部322与轴流风机的叶片在风路上形成接力，进一步保证空气净化装置的出风量。
由于水箱10内还需要设置杀菌瓶等结构，因此，甩水叶片32的转动范围在水平面内的投影面积是小于出风口面积的，会有部分气体未经净化和加湿而经水箱10侧壁与甩水叶片32之间的空间排出。针对这一问题，在一个优选的实施例中，图5是本申请再一实施例的空气净化装置中甩水结构的主视图，如图5所示，甩水叶片32还包括由叶片主体部321的上部向径向外侧延伸设置的第二延伸板部323，多个甩水孔还包括设置于第二延伸板部323上的第三甩水孔3231，通过第二延伸板部323对水箱10的上部空间区域进行补偿，从而进一步提高空气净化装置的空气净化和加湿效率。
可以理解的是，第一延伸板部322和第二延伸板部323可根据具体需求进行设置，即，甩水叶片32可以仅在叶片主体部321上设置第一延伸板部322，也可以仅在叶片主体部321上设置第二延伸板部323，还可以是叶片主体部321上既设置第一延伸板部322又设置第二延伸板部323。
为了将进风口进入的空气更多地向下引流至甩水叶片32的下部区域，示例性地，如图1所示，水箱10可以包括水箱本体11和设置于水箱本体11内的分隔套筒12，进风口设置在水箱本体11的侧壁上，出风口设置在水箱本体11的顶部，分隔套筒12由水箱本体11的顶部延伸至进风口的下方。如图2所示，通过设置分隔套筒12，使得进风口进入的气流不会直接流动至与进风口高度一致的甩水叶片32区域，而是在分隔套筒12的引流作用下绕过分隔套筒12的底端，同时在轴流风机的作用下将气体的流动方向拉平，并进一步向上流动。这样，既能够延长气流的流动路径，又能够将气流引流至水分更多的甩水叶片32下部区域，从而进一步提高空气净化装置对气体的水洗效果和水洗效率。
示例性地，分隔套筒12的底端向径向内侧延伸形成有分隔环板，与第二延伸板部323类似地，分隔环板的设置也能够避免气流直接由分隔套筒12与甩水叶片32之间的空间排出。
在另外的实施例中，图6是本申请还一实施例的空气净化装置中甩水叶片的横截面示意图，如图6所示，甩水叶片32还可以设置为波浪形，具体地，甩水叶片32包括至少一层波浪板层324，波浪板层324包括多个第一弯曲部3241和多个第二弯曲部3242，第一弯曲部3241和第二弯曲部3242沿中轴部31的轴向延伸，第一弯曲部3241和第二弯曲部3242的横截面均呈弯曲形且弯曲方向相反，在一层波浪板层324中，多个第一弯曲部3241和多个第二弯曲部3242沿中轴部31的径向交替相连，从而形成波浪形结构。每个第一弯曲部3241上均设置沿其延伸方向间隔排列的多个甩水孔，每个第二弯曲部3242上均设置沿其延伸方向间隔排列的多个甩水孔。
通过将甩水叶片32设置为波浪形，并在波浪形的每一个弯折部中均设置竖向间隔排 列的甩水孔，通过波浪形的甩水叶片32能够更好地将气流打散，使得气流更加均匀地通过甩水孔，以提高对气流的加湿和净化效果。
波浪板层324可以设置为单层板，也可以设置为多层板，在一个示例性的实施例中，如图6所示，甩水叶片32包括层叠设置的多层波浪板层324，相邻的波浪板层324的第一弯曲部3241和第二弯曲部3242在中轴部31的径向上均错开设置。即，相邻的波浪板层324中，其中一波浪板层324的第一弯曲部3241在中轴部31的径向上不会正对另一波浪板层324的第一弯曲部3241，同样地，其中一波浪板层324的第二弯曲部3242在中轴部31的径向上不会正对另一波浪板层324的第二弯曲部3242。如此，在波浪板层324之间形成多条沿竖向延伸的水流通道，从而能够将水箱10内的水更多更快地吸收并均匀分散至甩水叶片32的各个位置，从而进一步提高空气净化装置的水洗效果和水洗效率。
甩水孔的孔径不宜过大，也不宜过小，甩水孔过大会导致漏风，影响对空气的加湿和净化效果，甩水孔过小会增加空气的阻力，影响空气净化装置的空气净化效率和出风量。在一个示例性的实施例中，甩水孔的孔径为3-5mm，例如，甩水孔的孔径可以设置为3mm、4mm、5mm等尺寸。这样，既能够保证空气净化装置对空气的加湿和净化效果，又能够保证空气净化效率及出风量。
电机的电机轴可以直接与甩水结构30的中轴部31连接，为了方便装配，如图1所示，空气净化装置还可以包括传动轴40，电机的电机轴通过传动轴40与中轴部31相连。如图1所示，传动轴40可以包括相连的第一连接段41、第二连接段42和第三连接段43，第二连接段42的外径大于第一连接段41、第三连接段43的外径，以在第一连接段41与第二连接段42之间形成第一台阶面，在第二连接段42和第三连接段43之间形成第二台阶面。如此，第一连接段41与中轴部31传动连接，例如相互套接，第三连接段43穿过水箱10的底壁并与电机相连，中轴部31抵靠于第一台阶面上，第二台阶面抵靠于水箱10的底壁上。这样，通过第一台阶面对甩水结构30形成支撑，使得甩水叶片32既可以距离水箱10的底壁足够的近，保证甩水叶片32有更多的结构伸入水箱10的水中，又能够避免甩水叶片32转动而与水箱10的底壁发生干涉。
第三连接段43可以直接与电机的电机轴固定连接。为了方便水箱10换水，在示例性的实施例中，图7是本申请实施例的空气净化装置中，传动轴与电机的电机轴配合处的结构示意图，如图7所示，传动轴40穿出水箱10的部分即第三连接段43上设置有第一锥齿轮51，电机20的电机轴21顶部设置有第二锥齿轮52。这样，当水箱10装入空气净化装置的外壳内时，第一锥齿轮51与第二锥齿轮52相啮合，使得电机20的电机轴21与传动轴40形成传动连接。将水箱10上提，第一锥齿轮51和第二锥齿轮52分离即可将水箱 10顺利取出。
在水箱10装入空气净化装置的外壳内时，第二台阶面抵靠于水箱10的底壁上，为了减小传动轴40的转动阻力，当水箱10装入空气净化装置的外壳内时，第二锥齿轮52能够将第一锥齿轮51上顶，使得第二台阶面离开水箱10的底壁。
为了保证甩水叶片32在轴向上的位置可靠性，传动轴40还可以包括与第一连接段41的顶部相连的第四连接段，第四连接段螺纹连接有限位螺母，如此，通过限位螺母对甩水结构30进行轴向的限位，保证甩水结构30的转动可靠性。
本申请实施例还提供了一种空调，其包括空调本体和如上所述的空气净化装置。空调本体包括换热器、风机等结构，用于对空气温度进行调节，例如对空气进行升温、降温等处理，当然，可以理解的是，空调本体还可以对空气进行加湿、除湿等处理。空调本体和空气净化装置可以共用一个外壳，也可以各自设置单独的外壳。空气净化装置还可设置为与空调本体协同工作，例如，空气净化装置净化加湿后的气体可进入空调本体内换热后排出空调，或者空调本体内换热后的气体可进入空气净化装置净化加湿后排出空调。
本申请实施例提供的空调中设置有上述的空气净化装置，空气净化装置的结构简单，易于装配，从而提高空调整体的装配效率，降低空调的生产成本。
至此，已经结合附图所示的实施方式描述了本申请的技术方案，但是，本领域技术人员容易理解的是，本申请的保护范围显然不局限于这些具体实施方式。在不偏离本申请的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本申请的保护范围之内。
