在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
下面参考图1-图15描述根据本申请实施例的空气处理组件100，该空气处理组件100可以安装在清洁设备1000中用于对空气进行过滤。可选地，清洁设备1000可以为扫地机器人。
如图1-图12所示，根据本申请实施例的空气处理组件100，包括：第一集尘腔10、旋风分离器2和第二集尘腔11，其中第一集尘腔10具有第一进灰口101和第一出口。具体地，清洁设备1000包括清洁进灰口202，清洁进灰口202与第一进灰口101连通，在清洁设备1000运行过程中，吸入的携带灰尘等杂物的空气通过清洁进灰口202和第一进灰口101进入到第一集尘腔10内。
旋风分离器2包括分离腔20和分离件21，分离腔20具有分离进口201、分离出气口203和第一出尘口202，分离进口201与第一出口连通，分离件21设在分离腔20内，分离件21内设有气体通道210，分离件21的周壁设有与气体通道210连通的进气口，进气口与分离进口201连通，气体通道210与分离出气口203连通。
第二集尘腔11具有第二进灰口114，第二进灰口114与第一出尘口202连通。可以理解的是，旋风分离器2的分离出气口203可以与空气驱动件6相连，空气驱动件6工作时可将外界空气通过第一进灰口101吸入到空气处理组件100内。优选地，空气驱动件6可以为真空发生器，从而可以利用正压气源在空气处理组件100内产生负压，保证空气可以进入到空气处理组件100内。
具体而言，如图6和图7所示，其中实线箭头为灰尘走向，虚线箭头为气流走向，携带灰尘等杂物的空气通过第一进灰口101进入到第一集尘腔10内，在重力作用下，空气中的大尺寸较重的灰尘沉积在第一集尘腔10内，然后其余灰尘在空气流动作用下从第一出口和分离进口201进入到分离腔20内，进入分离腔20内的空气在切向力的作用下绕分离件21旋转，空气通过进气口进入到气体通道210内，然后通过分离出气口203排出分离腔20，在离心力的作用下，灰尘会从空气中分离出来并通过第一出尘口202和第二进灰口114排入到第二集尘腔11内。也就是说，进入到空气处理组件100 内的空气先利用重力作用将比重较大的灰以及尺寸较大的灰在第一集尘腔10内分离，然后较细的灰再经过旋风分离器2进行二次旋风分离。需要进行说明的是，采用旋风分离技术分离灰尘的分离原理已为现有技术，这里就不进行详细描述。
需要进行说明的是，为了保证清洁设备1000的吸灰要求，清洁设备1000的清洁进灰口202一般为长条形。但是由于旋风分离器2的分离进口201一般为矩形，如果将旋风分离器2的分离进口201与清洁进灰口202直接相连，会导致与其相连的清洁进灰口202很小，无法满足吸灰需求，导致清洁设备1000的起尘性能下降。根据本申请实施例的空气处理组件100，通过将分离进口201与第一集尘腔10的第一出口连通，将第一集尘腔10的第一进灰口101与清洁进灰口202相连，从而可以根据吸灰要求将清洁进灰口202设置为长条形，保证了清洁设备1000的起尘性能。
根据本申请实施例的空气处理组件100，通过设置第一集尘腔10、旋风分离器2和第二集尘腔11，先利用重力原理进行第一次灰尘分离后再利用旋风分离器2进行第二次灰尘分离，从而进入到旋风分离器2内的灰尘不会干扰分离腔20内的流场，保证了旋风分离器2的分离效率，可以避免旋风分离器2发生堵灰的情况，保证空气处理组件100的除尘效果，同时无需串联多个旋风分离器2，使得空气处理组件100的体积较小，可以应用到扫地机器人等清洁设备1000中。同时可以保证清洁设备1000的起尘性能。
在本申请的一些实施例中，分离进口201位于分离腔20的顶部，第一出尘口202位于分离腔20的底部。从而通过分离进口201可以进行高处进灰，然后气流在重力作用下螺旋向下运动，在旋风分离器2底部的第一出尘口202甩出灰尘，可以保证第一集尘腔10内大比重灰沉积在第一集尘腔10内，大比重灰难以被吸入到分离腔20内，旋风分离器2不会出现堵灰现象，分离腔20内底板上不会出现灰尘堵塞现象。在本申请的具体示例中，分离件21形成为圆柱状，分离件21的周壁设有多个进气口，多个进气口在周向和轴向上间隔分布。
如图1-图7所示，在本申请的一些实施例中，空气处理组件100还包括出风通道3，出风通道3与分离出气口203连通，出风通道3的出风端设有过滤件4。具体地，从分离出气口203排出的空气会经过过滤件4进行第三次过滤，从而可以进一步提高空气处理组件100的过滤效果，还可以延长过滤件4的使用寿命。可选地，过滤件4可以为过滤网或者是HEPA(High efficiency particulate air Filter，空气过滤器)。
进一步地，如图3、图4、图6和图7所示，空气处理组件100还包括安装支架5，安装支架5设在出风通道3的出风端，过滤件4安装在安装支架5上。从而便于过滤 件4的安装固定。可选地，出风通道3的周壁可以卡设在安装支架5的卡槽内，从而便于安装支架5的安装且避免发生漏风现象。
如图1-图7所示，在本申请的一些实施例中，空气处理组件100还包括空气驱动件6，空气驱动件6安装在安装支架5上且位于过滤件4的下游，空气驱动件6驱动空气从第一进灰口101进入空气处理组件100。从而便于空气驱动件6的安装装配，保证了空气可以顺序流经第一集尘腔10、旋风分离器2和过滤件4，保证空气处理组件100的过滤效果。
根据本申请的一些实施例，如图3和图7所示，第一集尘腔10内设有分隔板12以将第一集尘腔10分隔成连通的第一腔室102和第二腔室103，第一腔室102位于第二腔室103的下方，第一腔室102设有第一进灰口101，第二腔室103设有第一出口。从而通过设置分隔板12可以将大比重的灰尘沉积在第一腔室102内，可以避免大比重的灰尘被吸入到旋风分离器2内。可选地，分隔板12可以形成为格栅状、网状或者是平板状。分隔板12的设置角度不限制于水平放置，还可以是竖直放置或者是倾斜设置。具体地，第一出口通过进风风道22与分离进口201连通。
为了保证进入到第二集尘腔11内的灰尘可以沉积在第二集尘腔11内，如图4所示，在本申请的一些实施例中，第二集尘腔11内设有积灰板13。从而进入到第二集尘腔11内的灰尘由于积灰板13的阻挡作用而减速沉积下来。
优选地，如图4所示，第二集尘腔11的至少两个相对设置的侧壁上设有积灰板13，相对设置的侧壁上的积灰板13在远离第二进灰口114的方向上朝向彼此倾斜延伸。也就是说，第二集尘腔11内设有多个积灰板13，多个积灰板13可以仅设置在第二集尘腔11的两个相对设置的侧壁上，多个积灰板13还可以分布在第二集尘腔11的每个侧壁上，积灰板13的个数及设置位置可以根据实际情况进行选择。设置在相对设置的两个侧壁上的积灰板13为倾斜设置的板体，从而积灰板13不仅可以阻挡灰尘还可以起到导向的作用，可以防止灰尘返灰。设置在第二集尘腔11的其余侧壁的积灰板13的形状可以根据实际情况进行设定，例如可以形成为平板状。
为了避免进入到第二集尘腔11内的灰尘发生返灰现象，在本申请的一些实施例中，在灰尘的流动方向上，第二集尘腔11被构造成具有至少一个拐弯部110，从而使得进入到第二集尘腔11内的灰尘由于拐弯部110的阻挡作用，不会从第一出尘口202逃逸。
具体地，第二集尘腔11包括高度不同的底壁，相邻的两个底壁限定出一个拐弯部110。从而使得第二集尘腔11的结构简单。在本申请的一些具体示例中，如图5所示，第二集尘腔11包括第一底壁111、第二底壁112和连接壁113，第二底壁112位于第 一底壁111的上方，连接壁113的上下两端分别与第一底壁111和第二底壁112相连，第一底壁111、第二底壁112和连接壁113形成为台阶状以限定出拐弯部110。
根据本申请的一些实施例中，如图1和图5所示，分离腔20上设有与分离腔20连通的清理口，旋风分离器2还包括用于打开或封闭清理口的封闭盖7。从而在封闭盖7打开清理口时，用户可以通过清理口清理旋风分离器2内部堵塞的毛发等垃圾，进而可以有效避免旋风分离器2内部堵塞。
在本申请的一些实施例中，如图1-图11所示，空气处理组件100包括尘盒1，尘盒1内限定出第一集尘腔10和第二集尘腔11，旋风分离器2设在尘盒1上。从而通过设置一个尘盒1可以限定出第一集尘腔10和第二集尘腔11，使得空气处理组件100的结构简单。当然可以理解的是，第一集尘腔10和第二集尘腔11的形成形式不限于此，例如可以是设置两个独立的杯体以分别限定出第一集尘腔10和第二集尘腔11。
如图1-图7所示，在本申请的一些实施例中，尘盒1的外周壁设有向内凹入的安装缺口，旋风分离器2设在安装缺口处。也就是说，旋风分离器2外挂在尘盒1上，旋风分离器2和尘盒1在水平空间上部分重叠、高度方向上错位布置，从而使得尘盒1体积有效减小且有效积灰容积不受影响，减少空气处理组件100的体积。可选地，为了避免发生漏风现象，尘盒1和旋风分离器2的连接处设有密封件8。在本申请的一些实施例中，如果清洁设备1000内部的空间够大，旋风分离器2可以设置为两个且分别布置于尘盒1两侧，每个旋风分离器2均设置有出风通道3，空气驱动件6分别与两个出风通道3相连，降低空气处理组件100的吸功损失。
具体地，如图1、图3和图7所示，旋风分离器2还包括连接在分离进口201的进风风道22，进风风道22与第一出口相连，从而便于旋风分离器2的装配。
如图8-图11所示，在本申请的另一些实施例中，旋风分离器2安装在尘盒1内部。灰尘进入到第一集尘腔10后可以直接分离然后进入旋风分离器2中，最后被分离进入到第二集尘腔11内，从而使得空气处理组件100的密封性更佳，不易漏灰，结构简单，用户可以将旋风分离器2和尘盒1一同取出。由于旋风分离器2设在尘盒1内部，可以根据实际需求设置分离进口201的个数，在本申请的一些优选示例中，分离进口201为多个且沿气体通道210的周向间隔分布。从而使得旋风分离器2内流场更加均匀，内部摩擦损耗更小，降低旋风分离器2内的吸力损失，同时由于流场更加均匀，灰尘旋转时不会在旋风分离器2内偏心运动，从而减少了灰尘从短流路直接逃逸的比例，提高灰尘分离效率。
根据本申请的一些实施例，第一集尘腔10的底壁和第二集尘腔11的底壁分别设有 排灰口，尘盒1上设有用于打开或关闭排灰口的开关门。从而当开关门打开时，在重力作用下灰尘脱离尘盒1，便于清理第一集尘腔10和第二集尘腔11内的灰尘，无需将整个尘盒1取出。可选地，开关门可转动地设在尘盒1上，开关门朝下转动时打开排灰口。从而便于开关门的打开，且打开状态的开关门不会影响出尘。在本申请的具体示例中，第一集尘腔10的底壁敞开，第二集尘腔11的底壁敞开，第一集成腔10的底壁和第二集尘腔11的底壁平齐，开关门为平板，从而使得尘盒1的结构简单。
如图13-图15所示，根据本申请实施例的清洁设备1000，包括：清洁部件和空气处理组件100，其中清洁部件具有清洁进灰口202。空气处理组件100为根据本申请上述实施例的空气处理组件100，第一进灰口101与清洁进灰口202连通。可选地，清洁设备1000为扫地机器人。
具体地，清洁部件可以包括滚刷300等结构，在清洁部件进行清扫时，携带灰尘等杂物的空气被吸入且通过清洁进灰口202流向空气处理组件100，进入到空气处理组件100内的空气先利用重力作用将比重较大的灰以及尺寸较大的灰在第一集尘腔10内分离，然后较细的灰再经过旋风分离器2进行二次旋风分离。
根据本申请实施例的清洁设备1000，通过设有上述的空气处理组件100，进入到旋风分离器2内的灰尘不会干扰分离腔20内的流场，保证了旋风分离器2的分离效率，可以避免旋风分离器2发生堵灰的情况，保证空气处理组件100的除尘效果，可以保证清洁设备1000的起尘性能。
在本申请的一些实施例中，清洁设备1000包括机壳200、滚刷300和驱动轮400，机壳200内设有滚刷腔201，滚刷300可转动地设在滚刷腔201内，驱动轮400可转动地设在机壳200上以带动清洁设备1000行走。清洁进灰口202位于滚刷腔201内，清洁设备1000在驱动轮400的作用下驶向灰尘区域，滚刷腔201内的滚刷300转动将灰尘卷起，空气驱动件6产生的负压使得气流从外部流入滚刷腔201进而携带灰尘通过清洁进灰口202和第一进灰口101进入到空气处理组件100中。
如图13所示，在本申请的一些示例中，尘盒1位于两侧的驱动轮400之间，尘盒1的前部位于滚刷腔201的上部以与滚刷腔201部分重叠。当然可以理解的是，尘盒1可以设置在清洁设备1000的最尾部，旋风分离器2布置在尘盒1一侧(在清洁设备1000的左后或右后)，空气驱动件6则通过出风通道3布置于清洁设备1000的前部。
如图15所示，根据本申请的一些实施例，滚刷腔201上设有起灰刮条500，从而起灰刮条500可以配合滚刷300完成起灰过程，提高清洁设备1000的起灰效果。
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。
