需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
在本申请中，在未作相反说明的情况下，使用的方位词如“上、下、顶、底”通常是针对附图所示的方向而言的，或者是针对部件本身在竖直、垂直或重力方向上而言的；同样地，为便于理解和描述，“内、外”是指相对于各部件本身的轮廓的内、外，但上述方位词并不用于限制本申请。
请参阅图1至图7所示，本申请提供了一种清洁设备，所述清洁设备用于待清洁面(例如水平地面)的清洁。所述清洁设备通过向待清洁面喷射清洁液，以对待清洁面进行湿式清洁，并将污水吸入其污水箱内，从而实现对待清洁面的清洁。
在一种示意性的场景中，所述清洁设备为洗地机，用于对地面进行清洁作业。值得注意的是，上述举例中所述清洁设备为洗地机，仅是所述清洁设备一种适用场景，所述清洁设备也可以为其他类型的清洁设备，例如，擦地机、擦窗机等。
下文将主要以所述清洁设备为洗地机为例进行说明，但基于上文描述可知，本申请实施例的保护范围并不因此而受到限定。
请参阅图1至图3所示，所述洗地机包括：机体700和可拆卸设于机体700上的箱体100。上述箱体100为污水箱，用于收容清洁地面时所产生的污物。污物可以理解为固体介质和液体介质的混合物。机体700上设有抽吸装置710，抽吸装置710为负压发生器，用于在箱体100内形成抽吸气流，进而将 地面上的污物吸入上述箱体100内。
箱体100包括箱本体(图中未示意)和箱盖(图中未示意)。箱本体呈内部中空且一端部开口设置，以在箱本体内部形成容纳腔110。其中，箱本体为有且仅有一个容纳腔110的整体式结构。箱盖密封设于箱本体的容纳腔110的开口处。
请参阅图3所示，箱本体上还设有进液机构200，进液机构200上设有进污通道。进液机构200还具有与进污通道连通的出液口210，出液口210与箱本体的容纳腔110连通。在本实施例中，进液机构200的出液口210悬空设于容纳腔110内。
具体地，进液机构200为管状件，进液机构200沿箱本体的纵长方向延伸。进液机构200具有固定端211和悬空端212，固定端211固设于容纳腔110的腔壁上，悬空端212悬空设于容纳腔110内。出液口210形成于悬空端212上。
请参阅图4所示，箱本体的侧壁的顶部设有第一开口120，第一开口120与箱体100外部的气流通道711连通。在本实施例中，气流通道711远离第一开口120侧的一端与抽吸装置710的进风端连通、靠近第一开口120侧的另一端与容纳腔110连通。也就是说，气流通道711用于连通箱本体的容纳腔110与抽吸装置。由此，容纳腔110内能够形成抽吸气流，从而将外部的污物和气流一并吸入箱体100内。
在本实施例中，所述洗地机具有箱本体相对地面倾斜时的第一工作状态、箱本体大致平行于地面时的第二工作状态。应予说明，在本说明书中，“箱本体大致平行于地面”是指箱本体平行于地面或者箱本体与地面的夹角小于等于10°。
具体地，第一工作状态为所述洗地机清洁开阔环境时的工作状态，例如，客厅、走道等无遮挡的环境；第二工作状态为所述洗地机清洁较为低矮环境时的工作状态，例如，沙发底、床底等高度较低的清洁环境，所述洗地机为了能够伸入至上述低矮的空间，机体700势必要贴近地面，从而迫使箱体100也贴近地面。机体700贴近地面的极限状态为大致与地面平行的状态，此时，箱体100也大致与地面平行。
在本实施例中，箱本体包括一组相对设置的第一侧壁101和第二侧壁102。进液机构200与第一侧壁101的距离大于进液机构200与第二侧壁102的距离。也就是说，进液机构200靠近第二侧壁102分布。当所述清洁设备处于上述第一工作状态时，箱本体相对地面倾斜，在竖直方向上，第二侧壁102位于第一侧壁101上方。上述“竖直方向”是指图1中的上下方向。当所述清洁设备处于上述第二工作状态时，第二侧壁102也位于第一侧壁101上方，由于进液机构200与第一侧壁101的距离大于进液机构200与第二侧壁102的距离，使得箱体100能够在进液机构200与第一侧壁101之间存储更多的污水，从而增大箱体100的污水容量。
为了避免容纳腔110内的液体介质跟随抽吸气流进入负压发生器内，所述洗地机还包括转动组件，转动组件被配置为实现箱本体的气液分离。转动组件固定于机体700上，容纳腔110通过转动组件与上述气流通道连通。通过将转动组件固定于机体700上，一方面，由于控制单元位于机体700上，在将转动组件设于机体700上后，有利于转动组件与机体700之间的线路连接，接线和布线更为方便，布局合理；另一方面，可释放箱体内部的空间，在一定程度上，能够提高箱体内部空间的利用率。
箱体100具有连接至机体700上的第一状态、与机体700脱离的第二状态。在第一状态下，请参阅图3所示，转动组件的至少部分通过第一开口120延伸至容纳腔110内。在第二状态下，请参阅图2所示，转动组件的该部分通过第一开口120移出容纳腔110。
在本实施例中，请继续参阅图3并结合图8所示，转动组件包括叶轮400和驱动件500。在箱体100处于第一状态下，叶轮400位于容纳腔110内，且靠近第二侧壁102侧分布。叶轮400上形成有进风口430，进风口430与气流通道711连通，抽吸装置710通过气流通道711与转动组件的进风口430连通。其中，叶轮400上设有多个进风口430，多个进风口430间隔分布于叶轮400的周向方向上。
为了使得容纳腔110内的气体仅通过转动组件的进风口430进入气流通道，增加箱体100与机体700之间的密封性能，箱本体与机体700之间设有第一密封结构130，请参阅图4至图6所示，机体700上与第一开口120对应的区 域和第一开口120至少其中之一上设有第一密封结构130。也就是说，第一密封结构130设于机体700上，或/和，第一密封结构130设于第一开口120处。在本实施例中，优选的，第一密封结构130为环形密封件，例如，橡胶密封圈、硅胶密封垫等，第一密封结构130设于所述机体700上与第一开口120对应的区域，且第一密封结构130环设于转动组件的周边，第一密封结构130紧邻转动组件，防止气流从转动组件的周边流入气流通道；在箱体100安装于机体700上后，第一密封结构130抵接箱本体的侧壁且环绕第一开口120，防止气流从第一开口120溢出。由此，容纳腔110内的气体仅通过转动组件的进风口430进入气流通道内，具有气液分离效果好的优点。
在本申请的另一实施例中，第一密封结构130设于第一开口120处。具体地，第一密封结构130设于箱本体的外壁上，且围设于第一开口120的外周，在箱体100安装于机体700上后，第一密封结构130抵接机体700且环绕转动组件，从而能够有效避免气体通过第一开口120进入容纳腔110内。
在本实施例中，上述“转动组件的至少部分通过第一开口120延伸至容纳腔110内”可以理解为至少转动组件中的叶轮400通过第一开口120延伸至容纳腔110内。
驱动件500设于机体700上，驱动件500具有输出轴510，输出轴510与叶轮400连接，以驱使叶轮400转动，从而使得被吸入容纳腔110内的气体介质和液体介质在叶轮400离心力的作用下相互分离，进而使得液体介质被滞留在箱体100内，气体介质被排出箱体100。
关于输出轴510与叶轮400之间的连接形式，在一情况下，请继续参阅图3所示，输出轴510直接与叶轮400连接，输出轴510直接带动叶轮400转动，此时，叶轮400的旋转轴线与输出轴510同轴分布。
在另一情况下，叶轮400的旋转轴线与输出轴510之间可通过带传动，例如，通过同步带传动的方式驱使叶轮400转动，此时，叶轮400的旋转轴线与输出轴510相平行。
当输出轴510直接带动叶轮400转动时，在箱体100连接至机体700上后，驱动件500相对容纳腔110的位置有如下几种情况：第一种情况，驱动件500完全位于容纳腔110内；第二种情况，驱动件500的一部分位于容纳腔110 内、另一部分位于容纳腔110外；第三种情况，驱动件500完全位于容纳腔110外。
在本实施例中，优选的，驱动件500的一部分位于容纳腔110内、另一部分位于容纳腔110外。且在叶轮400的旋转轴线的方向上，叶轮400与驱动件500部分重叠。
请参阅图2所示，机体700上形成有一凹陷区，箱体100可拆卸设于凹陷区。其中，当箱体100安装于机体700上后，箱体100为机体700外壳的一部分。
在本申请另一实施例中，请参阅图5和图6所示，凹陷区形成有一朝向箱本体侧凸起的凸台720，转动组件设于凸台720处。箱本体的侧壁上凹陷形成有与凸台720配合的凹槽，凹槽的槽壁上设有上述第一开口120，至少转动组件中的叶轮400通过第一开口120可移除地设于容纳腔110内。
通过设置上述凸台720，可实现箱体100与机体700之间的安装对位。安装时，若要将叶轮400与第一开口120进行对准，对准的难度较大，费时费力。而若将凸台720与上述凹槽对位，则对位难度低，对位较为方便。
在本实施例中，请继续参阅图3所示，容纳腔110内还设有固液分离组件300，固液分离组件300将容纳腔110至少分隔为用于收容固体介质的第一收容室(图中未示意)和用于收容液体介质的第二收容室(图中未示意)。
出液口210位于第一收容室内，叶轮400位于第二收容室内。固液分离组件上设有过滤结构303，出液口210排出的流体(污物)中的固体介质在过滤结构303的作用下滞留于第一收容室内，液体介质则通过过滤结构303进入第二收容室内，以实现固体介质与液体介质的分离。
上述过滤结构303可以为设于固液分离组件上的若干过滤孔，也可以是设于固液分离组件上的滤网，还可以是其他具有固液分离功能的结构。
在本实施例中，请参阅图7所示，固液分离组件300包括止挡板302，叶轮400和出液口210分别位于止挡板302的相对两侧。止挡板302大致沿垂直与第一侧壁101或是第二侧壁102的方向延伸，将容纳腔110在纵长方向上分隔为上述第一收容室和第二收容室。其中，第二收容室相较第一收容室更靠近箱盖侧分布。
止挡板302包括中心区C，中心区C在箱体100的纵长方向上的投影与进液机构200的悬空端在箱体100的纵长方向上的投影完全重合。中心区C为连续结构，上述“连续结构”可以理解为中心区C上不设有通孔，或是镂空结构。止挡板302还包括围设于中心区C外周的延伸区，延伸区上设有上述过滤结构303。由此，经由出液口210喷射出的液体介质不会直接喷射至叶轮400上。
在本实施例中，止挡板302靠近出液口210侧的第一端面上设有套筒301，套筒301套设于进液机构200的悬空端处。也就是说，止挡板302通过套筒301连接至进液机构200的悬空端处。套筒301的套筒壁上还设有第二开口305，第二开口305与出液口210连通。其中，第二开口305可以朝向第一侧壁101，也可以朝向第二侧壁102，还可以同时朝向第一侧壁101和第二侧壁102。
止挡板302上还设有第三开口，第三开口处枢接有翻转板304，其中，翻转板304枢接于止挡板302靠近出液口210侧的第一端面上。当抽吸装置710工作时，翻转板304在抽吸气流的作用下克服自身重力的作用而覆盖于第三开口处，使得第三开口处于关闭状态，此时，第一收容室内的气流只能通过过滤结构303进入第二收容室内。当抽吸装置710停止工作时，翻转板304在自身重力的作用下朝向第一收容室方向翻转，此时，第三开口处于敞开状态。
显然，上述所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下，可以做出其它不同形式的变化或变动，都应当属于本申请保护的范围。
