具体实施方式
下面详细描述本申请的实施例，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，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考图1描述根据本申请第一方面实施例的差速装置100，该差速装置100可以应用在空气净化装置1000中。
如图1所示，根据本申请实施例的差速装置100包括电机10、内输出轴20和外输出轴30。具体地，电机10具有电机轴11，其中内输出轴20与电机10的电机轴11相连，并且内输出轴20和电机轴11为同轴同速转动，外输出轴30通过传动件与内输出轴20相连，这样，使得内输出轴20的转速和外输出轴30的转速不同，进一步地，外输出轴30具有中心孔，且外输出轴30套设在内输出轴20上。
由此，将电机轴11和内输出轴20设置为同轴同速转动，将外输出轴30套设在内输出轴20上，同时外输出轴30通过传动件与内输出轴20相连，如此，内输出轴20和外输出轴30可以保持不同的转速，内输出轴20和外输出轴30所分别带动部件的转速也不同，可以有效地避免由于内输出轴20和外输出轴30转速相同导致无法实现最佳的性能，从而提升了整机的工作效率。
其中，需要说明的是，外输出轴30和内输出轴20之间的传动件可以是摩擦轮传动机构、螺旋传动机构、齿轮组、皮带传动件、链传动件等，即可以实现外输出轴30和内输出轴20差速传动的部件均可，本申请对此不做具体限定。
可以理解的是，以将差速装置100应用在空气净化装置1000上为例进行说明，空气净化装置1000包括旋转筒80和旋转盘70，在净化分离领域，空气净化装置1000工作时，水液从位于中心的布水件的小孔或者雾化喷头喷出，水滴喷洒到高速旋转的旋转筒80，水滴被撕裂成液膜液体，并与旋转筒80和壳体内壁之间的气流混合，起到净化气流的作用，旋转盘70具有防止气流裹挟部分水滴逃离的功能，起到气液分离的作用。
相关技术中空气净化设备的转筒和转盘为一体驱动，即转筒和转盘为同转速转动，转筒的转速高低影响撕碎水的效果，进而影响净化效率，转盘的转速关系到对逃逸水滴的捕捉性能，也会影响净化效率。在很多情况下，转盘和转筒二者为同一转速转动时不能实现最佳净化功能，为实现更强的碎水效果时在需要转筒高转速的情况下，转盘如果同样提高转速，就会增大压强损失。有些情况下，对转盘截获水液的性能要求高，而对转筒的碎水效果要求不高时，若提高转筒的速度，则会增加能耗。
此外，为了解决上述实施例中转筒和转盘为同转速转动的问题，如果相关技术中的转筒和转盘分别采用两个电机驱动，即一个电机驱动转筒，另一个电机驱动转盘，虽然可以实现转筒和转盘的不同转速转动，但是会导致成本增高，能效降低。
然而，本申请实施例的差速装置100的内输出轴20和外输出轴30的转速不同，故内输出轴20和外输出轴30对应驱动的旋转部件的转速也不同，例如，内输出轴20与空气净化装置1000的旋转筒80相连，外输出轴30与空气净化装置1000的旋转盘70相连，这样，内输出轴20驱动旋转筒80转动，外输出轴30驱动旋转盘70转动，且旋转筒80和旋转盘70二者的转速不同，如在需要旋转盘70较高的转速的情况下，旋转筒80可以低速旋转，在需要旋转筒80较高的转速旋转的情况下，旋转盘70可以低速旋转，防止造成不必要的能耗，可以实现最佳的净化性能，节省能耗，且只需一个电机10驱动即可，不会导致成本增高，提升了工作能效。
综上所述，旋转盘70和旋转筒80对转速有不同的要求，满足旋转盘70和旋转筒80的要求才能发挥整机(例如空气净化装置1000)的最佳性能，因此将本申请实施例的差速装置100应用在空气净化装置1000上可以提升净化性能。
根据本申请实施例的差速装置100，通过将外输出轴30通过传动件与内输出轴20相连，使得外输出轴30与内输出轴20的转速不同，实现外输出轴30和内输出轴20的差速转动，进而可以驱动相应的旋转部件以不同的转速旋转，以提升整机(例如空气净化装置1000)的性能，节约能耗。
根据本申请的一个实施例，传动件包括齿轮组，其中齿轮组包括第一齿轮41、第二齿轮42和第三齿轮43，具体地，第一齿轮41套接在内输出轴20上，并且第一齿轮41 与内输出轴20保持同步转动，第二齿轮42与第一齿轮41啮合传动，如图1所示，第二齿轮42位于第一齿轮41的左侧，且与第一齿轮41处于同一轴向高度，第一齿轮41和内输出轴20同速转动，第一齿轮41和第二齿轮42通过啮合的方式进而带动第二齿轮42转动。
进一步地，第三齿轮43与第二齿轮42同轴设置且同步转动，可以理解的是，竖轴穿过第二齿轮42和第三齿轮43，并且竖轴与内输出轴20平行设置(如图1所示竖轴位于内输出轴20的左侧)，竖轴与第二齿轮42和第三齿轮43固定相连，第二齿轮42和第三齿轮43沿着竖轴的延伸方向上间隔开布置，第二齿轮42带动竖轴转动，进而带动第三齿轮43转动，故第二齿轮42和第三齿轮43保持同轴同速转动。
此外，在外输出轴30上设有齿轮部31，且第三齿轮43与外输出轴30上的齿轮部31啮合传动，如图1所示，齿轮部31位于第一齿轮41的正下方且与第三齿轮43啮合，第三齿轮43带动齿轮部31转动，进而驱动外输出轴30转动，综上所述，在外输出轴30和内输出轴20之间通过齿轮组的连接作用，在单独一个电机10的驱动作用下，即可实现内输出轴20和外输出轴30的差速传动，避免内输出轴20和外输出轴30始终为同速传动，将该差速装置100应用在整机(例如空气净化装置1000)上时，可以节省能耗，实现最佳的工作性能。
如图1所示，根据本申请一个可选的示例，差速装置100包括箱体50，在箱体50内限定出容纳腔50a，传动件位于容纳腔50a内，例如齿轮组位于容纳腔50a内，箱体50对传动件具有保护作用，内输出轴20从上至下贯穿容纳腔50a且向下延伸，如图1所示，内输出轴20的上端与电机10的电机轴11相连，内输出轴20的下端穿出箱体50向下延伸，以与对应的旋转部件相连。
根据本申请另一个可选的示例，差速装置100包括轴承组件，轴承组件设在内输出轴20和外输出轴30上，用于支撑内输出轴20和外输出轴30进行转动，以降低内输出轴20和外输出轴30运动过程中的摩擦系数，提升回转精度。
根据本申请又一个可选的示例，轴承组件包括第一轴承61和第二轴承62，在齿轮部31上的朝向电机10的一侧设有容纳槽，即齿轮部31的顶端设有容纳槽，第一轴承61外套在内输出轴20上，并且第一轴承61配合在容纳槽内，这样可以支撑内输出轴20转动，减小内输出轴20转动时的摩擦系数，提升内输出轴20的回转精度。
另外，在箱体50的内底壁上设有安装槽，第二轴承62配合在安装槽内，且第二轴承62外套在外输出轴30上，用于支撑外输出轴30转动，降低外输出轴30转动时的摩擦系数，提升外输出轴30的回转精度。
如图1所示，根据本申请又一个可选的示例，差速装置100还包括电机罩63，在电机罩63内限定出电机腔，电机10位于电机腔内，第一齿轮41远离齿轮部31的一端(即第一齿轮41的上端)沿轴向伸入电机腔内，以增大第一齿轮41与内输出轴20和电机轴11的接触面积，保证内输出轴20可以带动第一齿轮41转动，提高第一齿轮41和内输出轴20之间的连接可靠性。
进一步地，第一齿轮41包括齿轮主体411和轴套412，轴套412与齿轮主体411同轴相连，轴套412和齿轮主体411为一体成型，齿轮主体411与第二齿轮42啮合相连，轴套412伸入电机腔内且与电机轴11相连，轴套412与电机轴11同轴同速转动，轴套412套设在电机轴11上，电机轴11可以驱动轴套412以及齿轮主体411转动，进而带动第二齿轮42啮合传动，这样，可以增大第一齿轮41与电机轴11以及内输出轴20的接触面积。
可选地，差速装置100包括密封圈，密封圈连接在外输出轴30和箱体50之间，密封圈连接在第一齿轮41和箱体50之间，这样，可以使得外输出轴30和箱体50之间、第一齿轮41和箱体50之间紧密相连，进而提升箱体50内的密封性，避免从外输出轴30和箱体50之间、第一齿轮41和箱体50之间的缝隙向箱体50内渗水，实现***防水，可以有效地确保传动件不受到影响。
根据本申请第二方面实施例的空气净化装置1000，包括壳体、旋转盘70、旋转筒80、布水件和根据上述实施例中的差速装置100，在壳体上具有进气口和出气口，壳体限定出旋转腔，旋转腔连通进气口和出气口，旋转盘70可转动地设在旋转腔内，旋转筒80可转动地设在旋转腔内，并且旋转筒80设在旋转盘70的上游，所谓旋转盘70的上游，即指图1中沿着气流从下至上的方向上旋转盘70以下的区域，如图1所示旋转筒80位于旋转盘70的下方。
可以理解的是，在旋转腔的底部限定出储水空间，布水件可以引导旋转腔底部的水向上流动，并通过布水件的上端朝向旋转筒80内布水，进气口设置在壳体的侧壁上，且进气口位于净化组件的下方，布水件朝向旋转筒80内布水，水液被喷射至旋转筒80内后，高速旋转的旋转筒80将水液撕成细小的液滴，在离心力作用下，小液滴被甩向旋转腔的内壁的同时可以捕捉气流中的杂质颗粒物，部分携尘液滴被甩在旋转腔的内壁上，旋转盘70截获的气流中的液滴也抛向旋转腔的内壁上，水液在旋转腔的内壁上积聚并向下滑落。
此外，差速装置100设在旋转盘70的下游，所谓旋转盘70的下游，即指图1中沿着气流从下至上的方向上旋转盘70以上的区域，如图1所示差速装置100位于旋转盘 70的上方。进一步地，差速装置100的内输出轴20与旋转盘70和旋转筒80中的一个相连，差速装置100的外输出轴30与旋转盘70和旋转筒80中的另一个相连，例如内输出轴20与旋转筒80相连，外输出轴30与旋转盘70相连，可以控制旋转盘70和旋转筒80按照不同的转速转动，与相关技术中空气净化设备的转盘和转筒一体驱动且同步转动相比，可以实现最佳的净化性能，节省能耗。
需要进一步说明的是，旋转盘70包括多级，旋转筒80位于多级旋转盘70的上游侧，多级旋转盘70中每相邻两级旋转盘70之间设有隔筒71，如图1所示，旋转盘70包括两级，两级旋转盘70之间连接有隔筒71，隔筒71的外周壁为圆柱面，即隔筒71的外周壁形成为封闭的壁面，隔筒71的内部与隔筒71的外部不连通，例如隔筒71可以形成为不透风不透水的结构。隔筒71与壳体的侧壁间隔开设置，从而使得空气可从隔筒71与壳体之间的间隔空间通过。
具体地，隔筒71位于第一级旋转盘70的下游，第一级旋转盘70、隔筒71和第二级旋转盘70同步转动，隔筒71与壳体之间形成间隔空间，间隔空间可以适于空气通过，由此，通过第一级旋转盘70净化后的空气可以流经间隔空间，通过高速旋转的隔筒71，可加强流经间隔空间的空气的离心运动，从而有利于将空气中裹挟着的水滴抛向壳体的内壁面，进而利于气液的分离，提高净化效果。
例如，通过将差速装置100的内输出轴20与旋转筒80相连，外输出轴30与多级旋转盘70相连，通过内输出轴20和外输出轴30的差速转动，实现旋转筒80与多级旋转盘70的不同速转动，这样，可以使得旋转筒80和多级旋转盘70之间达到较好的配合状态，实现空气净化装置1000的最佳净化性能，节约功耗。
在本申请的描述中，“多级”的含义是两级或两级以上。
根据本申请实施例的空气净化装置1000，通过将外输出轴30通过传动件与内输出轴20相连，使得外输出轴30与内输出轴20的转速不同，实现外输出轴30和内输出轴20的差速转动，进而可以驱动相应的旋转部件以不同的转速旋转，发挥出空气净化装置1000的最佳性能，以提升空气净化装置1000的净化效率，定期更换滤网的次数很少，甚至无需更换滤网，使用十分方便，减小后期维护费用，降低了生产成本。
一些可选的示例中，空气净化装置1000包括第一连接器81，内输出轴20通过第一连接器81与旋转筒80固定相连，这样，可以更好地使旋转筒80和内输出轴20保持同步转动，具体地，第一连接器81包括第一连接块811和第一凸部812，在第一连接块811上具有第一通孔，内输出轴20穿过第一通孔且超出第一连接器81的下表面向下延伸，第一凸部812设在第一连接块811的顶部，这样，第一凸部812在环绕内输出轴 20的方向上填充在内输出轴20和旋转筒80之间，增大第一连接器81分别与内输出轴20和旋转筒80之间的接触面积，使得内输出轴20和旋转筒80之间连接可靠，进而始终可以保持同步转动。
一些可选的示例中，空气净化装置1000包括第二连接器，外输出轴30通过第二连接器与旋转盘70固定相连，这样，旋转盘70和外输出轴30可以同步转动，即旋转盘70和外输出轴30保持同转速。
进一步地，第二连接器包括第二连接块711和第二凸部712，第二连接块711上具有第二通孔，在外输出轴30的下端形成有配合部32，在第二连接块711的底部设有相应的凹槽，外输出轴30穿过第二通孔，并且配合部32配合在凹槽内，使得外输出轴30和第二连接块711之间配合可靠，第二凸部712设在第二连接块711的顶部，这样，第二凸部712在环绕外输出轴30的方向上填充在外输出轴30和旋转盘70之间，第二凸部712超出旋转盘70的上表面向上延伸，增大第二连接器分别与外输出轴30和旋转盘70之间的接触面积，使得外输出轴30和旋转盘70之间连接可靠，进而二者始终可以保持同步转动。
进一步地，空气净化装置1000还包括第三轴承90，第三轴承90设在第二连接器远离电机10的一侧，如图1所示，第三轴承90设在第二连接器的底端，第三轴承90外套在内输出轴20上，用以支撑内输出轴20转动，进一步减小内输出轴20转动时的摩擦系数，提升内输出轴20的回转精度。
根据本申请第三方面实施例的空气净化器，包括根据上述实施例中的空气净化装置1000和过滤装置。
具体地，过滤装置位于空气净化装置1000的上方，以对空气中剩余的颗粒物进一步净化。
根据本申请实施例的空气净化器，通过将外输出轴30通过传动件与内输出轴20相连，使得外输出轴30与内输出轴20的转速不同，实现外输出轴30和内输出轴20的差速转动，进而可以驱动相应的旋转部件以不同的转速旋转，发挥出空气净化装置1000的最佳性能，以提升空气净化器的净化效率。
此外，与相关技术中的净化设备相比，由于本申请实施例的空气净化器采用先通过水洗净化空气，这里所谓的水洗净化，即指本申请实施例的空气净化器中通过水液捕捉、吸附空气中的污染物后，并实现气液分离的净化方式，然后再通过过滤装置例如过滤网对水洗净化后的空气进一步净化，例如可以过滤掉空气中剩余的颗粒物，这样，既保证了对空气净化的纯净度，又减小了对过滤装置定期更换的次数，甚至无需更换滤网，只 需定期更换水即可，使用十分方便，降低了后期的更换、维护成本，用户体验好。
在本申请的描述中，需要理解的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“轴向”、“径向”、“周向”等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申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
根据本申请实施例的差速装置100、空气净化装置1000和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申请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申请的实施例，本领域的普通技术人员可以理解：在不脱离本申请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，本申请的范围由权利要求及其等同物限定。
