具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本公开，而不能理解为对本公开的限制。
下面参考附图描述根据本公开实施例用于空气净化的净化装置。
根据本公开实施例的用于空气净化的净化装置可以包括截获装置和水洗净化组件，其中，水洗净化组件可用于对空气进行水洗净化以对空气进行初步净化。
水洗净化组件可以为将空气通入水中的浸入式组件，也可以是水喷淋清洗组件或雾化水清洗组件等。其中空气经过水洗过滤后会含有一定的待除去的液滴，此外，还可能含有一些未被除尽的颗粒物及有毒有害气体。
由于空气经过水洗过滤后，许多液滴会随着空气一起向下游流动，且空气中仍旧含有一定的未被除去的颗粒物以及有毒有害气体，由此，需要进一步除去空气中的液滴以及颗粒物和有毒有害气体，以进一步地提高空气净化效果。
截获装置设在水洗净化组件的下游，可用于对水洗净化后的空气进行地净化，并可减小空气的含水量。
下面参考图1-图2描述根据本公开实施例的用于空气净化的截获装置100。
如图1和图2所示，根据本公开实施例的用于空气净化的截获装置100可以包括壳体1和截获组件20。
具体地，壳体1具有进气口11和出气口12，壳体1内限定出与进气口11和出气口12连通的空腔10，其中，水洗净化组件设在空腔10内。由此，空气可从进气口11进入空腔10，然后从出气口12流出，空腔10内可对空气进行水洗净化，通过对空气进行水洗过滤，从而可截获空气中的大部分颗粒物及有毒有害气体等。
截获组件20设在空腔10内且位于进气口11和出气口12之间，通过截获组件20可截获空气中的液滴，在此过程中，也能加剧液滴与空气中尘粒的接触，从而不仅能够降低空气的含水量，也可提高净化效果。
截获组件20包括旋转盘和圆筒2，旋转盘设有网孔，旋转盘包括第一旋转盘3和第二旋转盘5，第一旋转盘3和第二旋转盘5均可转动且第一旋转盘3与第二旋转盘5的转向相反，也就是说，第一旋转盘3和第二旋转盘5均可转动地设在空腔10内，且第一旋转盘3的旋转方向与第二旋转盘5的旋转方向相反，例如，第一旋转盘3可沿顺时针方向转动，第二旋转盘5沿逆时针转动，或者第一旋转盘3沿逆时针转动，第二旋转盘5沿顺时针转动。
第一旋转盘3设有第一网孔31，第二旋转盘5设有第二网孔51，第二旋转盘5设在第一旋转盘3的下游且与第一旋转盘3在轴向上间隔开设置，也就是说，在空气从进气口11到出气口12的流动方向上，第一旋转盘3和第二旋转盘5依次设置，空气依次流经第一旋转盘3和第二旋转盘5。
通过第一旋转盘3可对空气进行初级过滤以截获空气中的部分液滴，具体地，经过水洗过滤后的空气流向第一旋转盘3，由于第一旋转盘3高速转动，第一旋转盘3高速转动产生的剪切力可带动空气发生离心运动，在空气接触第一旋转盘3之前，使得空气中的部分液滴可从空气中分离出来。其中水洗净化后空气中含有的较小液滴会随着空气继续流动，并流向第一旋转盘3，空气流经第一旋转盘3时，空气中的液滴碰触第一旋转盘3，液滴在具有多个第一网孔31的第一旋转盘3上可铺展成沿薄液膜层或雾化成微小的液滴，薄液膜层或雾化的微小的液滴与通过第一旋转盘3的空隙的空气产生强烈的碰撞，从而可进一步地提高气液的接触面积，同时铺展开的液膜对空气中含有的粉尘颗粒也具有更加高效的捕捉作用，以进一步地强化除尘。而同时通过第一旋转盘3也可带动空气向下游继续流动，提高流动性。
第一旋转盘3和第二旋转盘5在空气的流通方向上间隔开设置，经过第一旋转盘3初步净化和截获后的空气流向第一旋转盘3和第二旋转盘5之间，由于第一旋转盘3与第二旋转盘5转动方向相反，第一旋转盘3和第二旋转盘5产生的剪切力相反，空气在第一旋转盘3和第二旋转盘5之间流动时受到方向相反的作用力，由此，使得空气在间隔空间21的沿周向方向的运动产生一定的抵消作用，从而降低了空气的周向运动速度，而空气中携带的液滴密度较大，惯性作用比气体大，因此从而使得液滴的运动相比空气运动改变较小，即由于惯性作用，空气中的液滴会继续做离心运动，而气体惯性作用相对液体较小，从而使得气体与液体更容易分开来，提高气液分离效果。
空气继续流向与第二旋转盘5，通过第二旋转盘5可对空气进行进一步地过滤以截获空气中的液体，从而可实现多级分离，不仅可提高净化效果，而且第二旋转盘5也可对过滤后的空气进行加速，使之做离心运动，提高净化效果，并可为空气流向出气口12提供动力。其中第二旋转盘5对空气的净化和对液滴的截获与第一旋转盘3原理相同，在此不再一一赘述。
圆筒2设在第一旋转盘3和第二旋转盘5之间，圆筒2的外周壁为圆柱面且与壳体1的侧壁间隔开设置。也就是说，圆筒2的外周壁形成为封闭的壁面，圆筒2的内部与圆筒2的外部不连通，例如圆筒2可以形成为不透风不透水的结构。如图1所示，圆筒2与壳体1的侧壁间隔开以限定出间隔空间21，空气可在间隔空间21内流通，由于第 一旋转盘3和第二旋转盘5的中心轴区域空气的周向速度小使得分离效果差，由此，通过设置圆筒2可避免空气从第一旋转盘3和第二旋转盘5的中心轴附近区域流过，从而可提高气液分离效果，进而提高净化效果。
根据本公开实施例的用于空气净化的截获装置100，通过截获组件20可以对水洗净化后的空气进一步地净化过滤，使得从出气口12流出的空气更加干净，由于第一旋转盘3与第二旋转盘5转动方向相反，剪切作用相反，空气流经第一旋转盘3与第二旋转盘5之间时受到不同方向的作用力，从而降低了空气的周向运动速度，其中空气中携带的液滴由于密度大，惯性力作用比气体大很多，会继续做离心运动，而气体惯性作用相对于液体较小，从而使得液滴更容易被分离出来。由此使得用于空气净化的截获装置100结构简单，净化空气的效果好。
根据本公开实施例的用于空气净化的净化装置，截获装置即上述实施例的用于空气净化的截获装置100，水洗净化组件设在空腔10内且设在进气口11和第一旋转盘3之间以用于对进气口11进入的空气进行水洗净化，由此，空气可从进气口11进入空腔10，并流向水洗净化组件，通过水洗净化组件可以对流经的空气进行水洗过滤，从而可去除空气中的大部分颗粒污染物及有毒气体等，然后经过水洗过滤后的空气流向第一旋转盘3，即水洗过滤后的空气可流向截获组件，通过截获组件不仅能够截获水洗过滤后空气中的液滴，降低空气的含水量，而且也可提高净化效果。
本公开的净化装置可用于家用空气净化领域，本公开的上述经净化装置能够去除1μm以上的颗粒污染物以及部分气态污染物，使得从出气口12排出的空气更加干净。而且现有技术中，在家用空气净化装置内大多设有过滤装置，例如海帕网等，本公开中通过截获组件20截获空气中的液滴，降低空气的含水量，从而可避免水洗过滤后空气中的液滴进入下游的过滤装置等，由此，不仅能够极大的减小后置过滤装置的负荷，也能够减小空气的含水量，防止过滤装置被水浸湿而滋生细菌，进而保证后置过滤装置的使用寿命和净化效果，使得较为干净地空气从出气口12排出。
其中第一旋转盘3和第二旋转盘5可在低转速下运行，在较低转速时从而不仅有利于将空气和空气中的液滴分离出来，也使得用于空气净化的截获装置100的结构稳定性更好，能耗低，还可以较好地降低噪音。
可选地，圆筒2可以为中空结构且形成为圆筒状的不透风件，由此，不仅可以减少空气净化的截获装置100的重量，同时还可以节约圆筒2的制作材料，节约生产成本。
在本公开的描述中，需要理解的是，术语“上”、“下”指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述。
在本公开的一些实施例中，第一网孔31可至少设在第一旋转盘3在径向方向上位于圆筒2和壳体1之间的部分上，第二网孔51至少设在第二旋转盘5在径向方向上位于圆筒2和壳体1之间的部分上，具体地，如图1所示，在空气流通的方向上(即如图1所示的上下方向)，第一网孔31可设在第一旋转盘3与间隔空间21对应的部分，第二网孔51设在第二旋转盘5与间隔空间21对应的部分上，由此，使得空气可在第一网孔31、间隔空间21和第二网孔51之间流动。从而不仅有利于空气的流动，保证空气的流通面积，也可减小空气阻力，进而使得空气中含有的液滴能够尽可能的分离出来。其中，对于旋转盘的结构而言，网孔可布满整个旋转盘，也可以仅设在旋转盘位于圆筒2和壳体1之间的部分上。
在本公开的一些实施例中，圆筒2的轴向上的至少一端形成为敞开结构，也就是说，圆筒2可以形成为轴向上一端敞开且一端封闭的结构，圆筒2也可以形成为两端均敞开的结构，其中，旋转盘在轴向方向上对应敞开结构的位置处不设有网孔。
在本公开的一些具体示例中，圆筒2可形成为下端敞开且上端封闭的结构，第一旋转盘3与圆筒2敞开处对应的部分不设有网孔，即第一网孔31仅设在第一旋转盘3位于圆筒2和壳体1之间的部分上，第一旋转盘3的中心位置处不设有网孔，以封闭圆筒2的下端敞开口，此时由于圆筒2上端封闭，第二旋转盘5对应圆筒2的部分可设有网孔也可不设网孔。
或者圆筒2的上端可形成为敞开结构，第二旋转盘5对应圆筒2的敞开结构的部分不设置网孔，以用于封闭圆筒2的上端敞开口，第二网孔51可仅设在第二旋转盘5位于壳体1和圆筒2之间的部分上，此时第一旋转盘3与圆筒2下端对应，第一旋转盘3与圆筒2的封闭结构对应的位置可设有网孔，也可不设网孔。
在本公开的另一些示例中，圆筒2的两端均敞开，此时，第一旋转盘3和第二旋转盘5与圆筒2的敞开结构对应的位置处均不设置网孔，即第一旋转盘3和第二旋转盘5的中心部分处均不设置网孔，第一网孔31仅设在第一旋转盘3位于圆筒2和壳体1之间的部分上，第二网孔51仅设在第二旋转盘5位于壳体1和圆筒2之间的部分上。
在本公开的另一些实施例中，圆筒2的两端均形成封闭结构，此时第一旋转盘3和第二旋转盘5与圆筒2轴向方向上相对应的位置可设有网孔，也可不设置网孔，即第一旋转盘3可布满第一网孔31，第一网孔31也可仅设在第一旋转盘3位于圆筒2和壳体1之间的部分上，第二旋转盘5可布满第二网孔51，第二网孔51也可仅设在第二旋转盘5位于壳体1和圆筒2之间的部分上。
其中对于第一旋转盘3和第二旋转盘5的结构而言，第一旋转盘3和第二旋转盘5 可形成为圆环状或者圆盘状，第一网孔31均匀分布在第一旋转盘3上，第二网孔51均匀分布在第二旋转盘5上，由此，第一旋转盘3和第二旋转盘5可形成为网状结构，从而可简化第一旋转盘3和第二旋转盘5的生产工艺。当然可以理解的是，第一网孔31和第二网孔51也可以是不均匀分布的。
在本公开的一些实施例中，圆筒2可固设在第一旋转盘3和第二旋转盘5之间且与第一旋转盘3和第二旋转盘5均不相连，即圆筒2固定设置，不可转动，圆筒2可设置单独的支撑结构。
在本公开的另一些实施例中，圆筒2可转动地设在第一旋转盘3和第二旋转盘5之间，由此，当空气在第一旋转盘3和第二旋转盘5之间流动时，圆筒2高速转动并产生剪切力，从而能够增强空气的离心运动的效果，以进一步地提高气液分离效果。
可选地，圆筒2与第一旋转盘3或第二旋转盘5中的一个固定相连，也就是说，在本公开的一些示例中，圆筒2可以与第一旋转盘3固定相连，通过第一旋转盘3带动带动圆筒2转动，即第一旋转盘3与圆筒2同步转动。在本公开的另一些示例中，圆筒2和第二旋转盘5固定相连，通过第二旋转盘5带动圆筒2转动，第二旋转盘5与圆筒2同步转动。由此可不需要设置单独的驱动结构，结构简单且方便装配。其中对于圆筒2与第一旋转盘3或第二旋转盘5的装配而言，圆筒2可与第一旋转盘3或第二旋转盘5卡接或者螺钉连接，也可以采用焊接等，对此，本公开不作限定。
当然可以理解的是，圆筒2也可以不与第一旋转盘3和第二旋转盘5相连，用于空气净化的截获装置100可设置单独的驱动结构来驱动圆筒2转动，或者圆筒2可通过其它连接部件与第一驱动件4或第二驱动件6相连。
在发明的一些具体示例中，如图1所示，圆筒2与第二旋转盘5相连，第二旋转盘5形成为环形盘，环形盘的内侧壁与圆筒2的外周壁相连，也就是说，第二旋转盘5形成为环形形状，第二旋转盘5可套设在圆筒2的外侧，第二旋转盘5的内侧壁与圆筒2的外侧壁固定连接，从而利于圆筒2与第二旋转盘5的固定装配，结构简单且装配方便。当然可以理解的是，第一旋转盘3也可以形成为环形盘。
可选地，第一旋转盘3和第二旋转盘5也可以形成为圆盘，例如，第一旋转盘3和第二旋转盘5均可以形成为圆盘，两个圆盘分别位于圆筒2的上方和下方，进一步地，第一旋转盘3和第二旋转盘5可以为两个正对放置的薄片形旋转盘，即第一旋转盘3可和第二旋转盘5均可以形成为薄片圆盘状，第一旋转盘3和第二旋转盘5在上下方向上正对设置且旋转方向相反。
对于第一旋转盘3和第二旋转盘5的结构而言，第一旋转盘3和第二旋转盘5可以 为丝网结构，从而使得第一旋转盘3和第二旋转盘5结构简单，方便生产和装配，也使得截获组件20可用于分离气流中含有的固体颗粒等，同时也使得第一网孔31和第二网孔51分布更加均匀，有利于液滴的截获和空气的通过。当然可以理解的是，第一旋转盘3和第二旋转盘5也可以是其他的结构形式，例如：辐条结构、型线的转盘结构等，对此本公开不做限定。
在本公开的一些实施例中，用于空气净化的截获装置100还包括第一驱动件4和第二驱动件6，第一驱动件4驱动第一旋转盘3转动，第二驱动件6驱动第二旋转盘5转动。也就是说，第一驱动件4和第二驱动件6的转动方向相反，以驱动第一旋转盘3和第二旋转盘5沿反向转动，由此第一旋转盘3和第二旋转盘5分别采用独立的驱动机构单独驱动，从而可以使得第一旋转盘3和第二旋转盘5在转动过程中互不影响，稳定性好。
在本公开的一些实施例中，第一旋转盘3设在第二旋转盘5的下方且与第二旋转盘5在上下方向上相对设置，第一驱动件4设在第一旋转盘3的下方，第二驱动件6设在第二旋转盘5的上方，从而不仅方便第一驱动件4和第二驱动件6的安装装配，也可避免第一驱动件4和第二驱动件6被液滴和灰尘侵蚀，保证第一驱动件4和第二驱动件6的安全性和可靠性。
可选地，第一驱动件4和第二驱动件6也可采用密封的形式，从而可进一步地防止第一驱动件4和第二驱动件6被液滴和灰尘侵蚀，提高第一驱动件4和第二驱动件6的使用寿命。
在本公开的另一些实施例中，用于空气净化的截获装置100还包括：驱动组件，驱动组件分别与第一旋转盘3和第二旋转盘5相连，驱动组件包括驱动装置和转向装置，驱动装置通过转向装置与第一旋转盘3和第二旋转盘5中的至少一个相连以使得第一旋转盘3与第二旋转盘5转动方向相反，也就是说，第一旋转盘3和第二旋转盘5可采用同一驱动装置驱动，从而可使得第一旋转盘3和第二旋转盘5同时转动。
具体地，第一旋转盘3和第二旋转盘5中的一个可与驱动装置相连且由驱动装置驱动，第一旋转盘3和第二旋转盘5中的另一个可通过转向装置与驱动装置相连，例如，第一旋转盘3可与驱动装置相连且由驱动装置驱动，第二旋转盘5可与转向装置相连以与驱动装置间接连接，这样，驱动装置可驱动第一旋转盘3转动，并可驱动转动装置以带动第二旋转盘5沿与第一旋转盘3相反的方向转动。其中，转向装置可以为齿轮组件，也可以为其他装置，只要能够驱动第二旋转盘5沿与第一旋转盘3转向相反的方向转动即可，对此本公开不作限定。
本公开还提出了一种具有上述实施例的用于空气净化的净化装置的空气净化器。
根据本公开实施例的空气净化器，通过设置上述实施例的用于空气净化的净化装置，可以较好地对空气进行过滤，能够去除1μm以上的颗粒污染物以及部分气态污染物，使得从出气口12排出的空气更加干净，而且可避免水洗过滤后空气中的液滴进入下游设置的过滤装置例如海帕网等，由此，不仅能够极大的减小后置过滤装置的负荷，也能够去除空气中含有的水分，防止海帕网被水浸湿后滋生细菌，保证后置过滤装置的使用寿命和净化效果，使得较为干净地空气从出气口12排出。
根据本公开实施例的空气净化器的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本公开的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本公开的实施例，本领域的普通技术人员可以理解：在不脱离本公开的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本公开的范围由权利要求及其等同物限定。
