本实用新型实施例的污水收集组件100，不仅能够实现固液分离，而且具有较好的气液分离效果，污水不容易进入到风机中，进而能够避免污水损坏风机。
配合图3所示，在一些实施例中，所述桶体111靠近顶端处的部分桶壁向外延伸形成第一台阶部115，所述第一进污口113沿竖向开设于所述第一台阶部115上。所述过滤提篮120靠近顶端处的部分篮壁向外延伸形成第二台阶部123，所述第二进污口121沿竖向开设于所述第二台阶部123上，所述第二台阶部123叠置于所述第一台阶部115的上方，且所述第一进污口113与所述第二进污口121相对。如此，方便第一进污口113与抽污管道连接，且易于实现第一进污口113和第二进污口121连通。
在一些实施例中，所述第一进污口113的周缘向上延伸形成第一导流筒116，所述第一导流筒116的顶端与所述第二台阶部123相抵接，并通过所述第二进污口121与所述导流空间118连通。这样，只要将过滤提篮120置于桶体111内，第一导流筒116的顶端就能够抵接在第二进污口121处，污水经由第一导流筒116和第二进污口121进入到过滤提篮120内，避免污水不经过滤而直接流入到污水桶110内。
配合图4所示，在一些实施例中，所述桶盖112的底面向下凸设有第一挡板117，所述第一挡板117的低端位于所述第二进污口121以下，所述桶盖112、所述第一挡板117和所述桶体111的部分内壁共同从所述第一桶腔中分隔出一低端开口的导流空间118，所述第二进污口121通过所述导流空间118与所述第一桶腔连通。该导流空间118能够将污水的流动方向调整为基本沿竖向流动，进而使得污水经过滤孔122过滤后，在重力和惯性的作用下仍然保持沿竖向的流动方向，气流折返后向上流动，具有较好的气液分离 效果。
配合图2和图3所示，在一些实施例中，所述第一挡板117邻近所述第二台阶部123的边缘，且所述第一挡板117的下缘与所述第二台阶部123的边缘形成狭长的低端开口。这样，污水能够贴近过滤提篮120的篮壁向下流动，甚至于部分污水沿着篮壁向下流动，能够避免污水飞溅。
可选的，该污水桶110和过滤提篮120的横截面形状均可呈矩形，该第一台阶部115可设置在污水桶110的拐角处，第二台阶部123可设置在过滤提篮120的拐角处，且第二台阶部123的横截面形成也可呈矩形，该第二台阶部123的两个边分别与过滤提篮120的两个相邻的篮壁相接，第一挡板117可沿着第二台阶部123的另两个边缘延伸，从而形成一横截面形状呈L形的第一挡板117，该第一挡板117和第二台阶部123之间形成一近似于L形的低端开口。
在一些实施例中，所述第二进污口121的顶部罩设导流罩124，该导流罩124具有朝向所述第一挡板117的侧方开口。导流罩124能够将污水导向第一挡板117，使得污水在第一挡板117的引导下沿竖向向下流动，避免污水飞溅到桶盖112上或污水桶110外，有益于保持洁净。
可选的，该导流罩124整体可近似于一筒状结构，该筒状结构的顶端封盖且周面上开设有朝向第一挡板117的侧方开口。该第一挡板117的横截面形状呈L形，该侧方开口可朝向该第一挡板117的拐角处。
配合图3和图4所示，在一些实施例中，所述污水收集组件100还包括第二导流筒130和浮动块140。第二导流筒130设置在所述桶体111内，所述第二导流筒130的顶端与所述第一出风口114连接，所述第二导流筒130的低端与所述第二桶腔连通。浮动块140可升降地设置在所述第二导流筒130内，所述浮动块140配置为随着所述桶体111内水位上升而升高，并在升高至预设位置时截断所述第二导流筒130内的气流流动。这样，当污水桶110中水位较高时，第二导流筒130和浮动块140配合封挡第一出风口114，避免污水被抽入风机中。
在一些实施例中，所述浮动块140与所述第二导流筒130的内壁之间具有间隙；所述第二导流筒130内设置第二挡板131，所述第二挡板131将所述第二导流筒130的筒腔分隔为靠近所述第一出风口114的第一筒腔133和远离所述第一出风口114的第二筒腔134，所述第二挡板131的中部开设有 通孔132，当所述浮动块140升高至所述预设位置时，封堵所述通孔132。
可选的，该第二导流筒130可为纵剖面形状呈倒L形且横截面形状呈长条形的扁平筒状结构，该第二导流筒130包括沿横向延伸的第一段和沿竖向延伸的第二段，该第二挡板131可沿横向设置在第二段的顶端处，从而将第二导流筒130的筒腔分隔为位于第一段内的第一筒腔133和位于第二段内的第二筒腔134。该第二挡板131的中部可设置有一长条形的通孔132。
该第二段的相对两侧桶壁上分别开设有沿竖向延伸的滑孔135，浮动块140的相对两侧分别凸设有滑块141，浮动块140设置在第二筒腔134内，且两个滑块141分别滑动连接于两个滑孔135内。当浮动块140的顶端与第二挡板131相抵接时，通孔132被封堵，而且在风机的吸力作用下，能够形成较好的密封效果。
在一些实施例中，所述过滤提篮120的内腔中设置有提手125，且所述提手125位于所述导流空间118外。将提手125设置在导流空间118外，能够避免污水飞溅到提手125上，有益于保持提手125洁净，方便用户使用。
可选的，该提手125可设置在远离第二进污口121的一侧篮壁上，该提手125的顶端可与过滤提篮120的上缘齐平，或缩于过滤提篮120的顶端敞口内，以避免该提手125与桶盖112干涉。
可选的，该提手125可包括设置在过滤提篮120的中部的板状结构，该板状结构的低端可与过滤提篮120的篮底连接，该板状结构的顶端处可设置有用于提拉的环状结构，该板状结构的顶端可与过滤提篮120的上缘齐平或缩于过滤提篮120内，如图5所示。
在具体实施时，为避免过滤提篮120的外壁与桶体111的内壁紧密贴合，导致过滤提篮120不易于取出，过滤提篮120的外壁与桶体111的内壁之间可设置有间隙。例如，可通过配置过滤提篮120的篮壁的倾斜角度，或者，通过配置过滤提篮120的横截面尺寸，以使得过滤提篮120的外壁与桶体111的内壁之间形成间隙。
参见图6所示，本实用新型实施例还提供了一种用于清洁机器人的基站，该基站包括机体、风机、抽污管道和如上任一项实施例所述的污水收集组件100，风机、抽污管道和污水收集组件100均可设置在机体内。所述抽污管道通过所述第一进污口113与所述第一桶腔连通，用于从停放在所述基站的清洁机器人的污水箱中抽取污水。所述风机通过所述第一出风口114与所述第 二桶腔连通，用于通过所述第一出风口114从所述第二桶腔中抽气，以为所述抽污管道提供抽吸动力。
由于上述污水收集组件100具有较好的气液分离效果，所以，应用该污水收集组件100的基站同样具有上述优点，污水不容易进入到风机中，避免污水损坏风机，有益于降低对风机的密封和绝缘要求。
以上实施例仅为本实用新型的示例性实施例，不用于限制本实用新型，本实用新型的保护范围由权利要求书限定。本领域技术人员可以在本实用新型的实质和保护范围内，对本实用新型做出各种修改或等同替换，这种修改或等同替换也应视为落在本实用新型的保护范围内。
