实施例一：
结合图1至8所示，在本发明实施例中，提供了一种电动拖把100，所述电动拖把100包括驱动电机(图中未示出)、清洁器121以及依附于所述清洁器121的擦头(图中未示出)，所述驱动电机与清洁器121连接以驱动擦头相对于待清洁表面运动以擦拭其表面的污物。所述待清洁表面可以是地面，所述运动可以是滑移运动。具体的，所述驱动电机至少为一个，所述清洁器121至少包括以下之一：相对于地面发生滚动滑移的清洁辊；相对于地面发生回转滑移的清洁转盘；相对于地面发生往复摆动滑移的清洁板。本领域人员可以理解地，所述擦头包括清洁垫、拖布和/或清洁条带。当然地，也包括一些它们相互组合的形态，例如清洁垫外包覆擦头，或者在擦头的周围额外设置清洁条带。此外，擦头可以通过魔术贴粘附于清洁器上，或者通过螺丝安装于清洁器上。
同时，本实施例中还提出了一种用于上述电动拖把的清洗装置200，所述清洗装置200包括具有清洗腔的清洗桶210和阀体220，清洗腔的底部设有通过阀体220选择性打开或封闭的漏水孔211，所述清洗腔内设具有清洗部件231的清洗机构230，所述清洗机构230上设有过水孔230b，所述阀体220封闭所述漏水孔，所述擦头与清洗部件231抵压并与清洗腔内的清洗用水接触以使运动的擦头刮蹭清洗；所述阀体220打开所述漏水孔211以排出污水并使运动的擦头脱干。清洗部件包括清洗筋和/或搓洗轮。可以理解的，所述漏水孔也可以称之为排水口，所述清洗机构也可以称之为支承架。
本实施例所揭示的电动拖把清洗装置，既能够让电动拖把在蓄有清洗水的清洗腔内进行清洗，又能够让电动拖把在排出污水后的清洗腔内进行脱干，从而高效便捷地实现了电动拖把完整的自清洁功能。该实施例中，清洗腔内设置有清洗机构，清洗部件设于清洗机构上背向清洗腔底壁的一面，供运动的擦头抵压于其上进行刮蹭，这不仅有助于刮落擦头上的污物，而且能够在电动拖把甩干的基础上进一步对擦头进行刮干，从而提升了电动拖把的清洗和脱干效果。该实施例中的电动拖把清洗装置，其清洗和脱干过程依赖电动拖把自身的搅动系统即可实现，因而无需再为电动拖把清洗装置配置额外的动力系统，从而大大节省了成本。相应地，电动拖把清洗装置在使用时，可以放置于阳台或洗手间的地漏附近以排放污水，在电动拖把淘洗和/或脱干完成后，只需打开阀体 即可排出拖把清洗腔内的污水，从而免去了用户的倾倒动作。
优选的，本实施例中还提出了电动拖把的一种优选方式，所述电动拖把100包括把杆110、枢转组件130和主机120，所述把杆110通过所述枢转组件130与主机120的后端铰接，所述驱动电机设于主机内，主机120的底部设有清洁转盘121，电机的输出轴从主机120的底部伸出并与清洁转盘121连接以驱动清洁转盘121转动。优选的，本实施例中的清洁转盘121为两个且在主机120的底部左右分别布置，所述清洁转盘121的底部设有魔术贴以将擦头固定贴合在清洁转盘121上。
具体的，所述擦头的旋转速度在100r/min-600r/min范围内，单个所述清洗部件的宽度在3mm-30mm范围内。该实施例中，擦头在清洁转盘的带动下，其旋转速度在100r/min-600r/min范围内，同时单个清洗部件的宽度在3mm-30mm范围内。其中，旋转速度的设置与电动拖把200的工作模式相关，电动拖把200在拖地、自动清洗以及刮干的过程中会对应不同的档位，不同档位下擦头的旋转速度会有所不同，可选择地范围在100r/min-600r/min的范围内。在如此高转速的情况下，需要考虑每个清洗部件的受力情况，一方面单个清洗部件的宽度不能过窄，否则相应的清洗部件会过于尖锐，不仅自身容易断裂，而且还会划伤、刮损擦头；另一方面，单个清洗部件的宽度如果过大，则擦头在旋转撞击清洗部件的过程中，所产生的撞击力和摩擦力将被较宽的面积均摊，这会导致刮蹭过程中相应的压强降低，从而影响电动拖把的自清洁效果，故优选地，单个所述清洗部件的宽度在3mm-30mm范围内。
参考图3-4所示，还揭示了本申请中电动拖把一些可能的结构。电动拖把的清洁器121除了采用清洁转盘外，还可以采用如图3所示的可相对于地面发生滚动滑移的清洁辊，也可以采用如图4所示的可相对于地面发生往复摆动滑移的清洁板。
可选的，所述清洗桶210与清洗机构230一体结构。优选的，本实施例中的所述清洗桶210与清洗机构230分体设置，所述清洗机构230可拆卸的架设在清洗腔中，使得清洗机构和清洗桶底之间形成有用于容置清洗水的空间，并且使得用户可以方便地对电动拖把清洗的过程中黏附在清洗桶和清洗机构表面的脏污进行清洗。所述清洗机构230的底部设有向下伸出的支撑部230a，所述支撑部230a抵接在清洗桶的底壁。
优选的，清洗桶210的侧壁上设有溢水孔212，所述清洗部件231的顶端不高于所述溢水孔的下沿所构成的水位界线。通过在清洗桶的侧壁上设置溢水口以限制所述清洗桶内液面的最高位置，防止水位太高而导致清洗时污水甩出清洗桶而弄污地面。
较佳的，在本实施例中，所述清洗装置200还包括具有污水腔的污水桶240，清洗桶210放置于污水腔的开口端，所述清洗腔分别通过漏水孔、溢水孔与污水腔连通，从而拓宽了电动拖把清洗装置的使用场所，使用户能够在客厅、卧室等不具有地漏的房间使用该电动拖把清洗装置，待电动拖把多次进行自清洁后，再将污水桶内蓄存的污水统一进行排放。
具体的，所述清洗装置200包括开阀机构，设于清洗腔下方的阀体220，和阀杆260，所述开阀机构在外力作用下驱动阀体枢转以使阀体动作。
在本实施例的一种可选方式中，如图5、6所示，所述开阀机构包括踏杆250，所述踏杆250与污水桶240铰接，踏杆250与污水桶240的铰接处还设有用于复位的扭簧。所述阀杆260与清洗桶210在阀杆的中部铰接，阀杆260与清洗桶210的铰接处也设有用于复位的扭簧。踏杆250的一端外露于污水桶240以供用户脚踏驱动，阀杆260的一端上设有所述用以封堵漏水孔211的阀体220，所述踏杆的另一端与阀杆的另一端传动配合，用户脚踩踏杆的外露端时，踏杆转动并带动阀杆转动以打开漏水孔211。
作为上述可选方式的一种变形，如图7所示，所述开阀机构还包括自锁连杆270，所述自锁连杆270与污水桶240铰接，踏杆250与阀杆260之间通过自锁连杆270传动连接，所述阀杆260远离阀体的一端设有自锁台阶260a，当所述自锁连杆270的靠近阀杆的一端卡入自锁台阶260a后，阀体220保持打开状态，从而使清洗腔内的污水持续通过漏水孔211排出至污水桶240中。用户踩踏踏杆250一次后，自锁连杆270的一端即卡入自锁台阶260a中，从而使阀体220保持打开状态，由此用户无需持续踩踏于踏板上即可将拖把清洗腔内的污水排尽；而当用户取出清洗桶210后，阀体和自锁连杆复位，方便下次使用。
作为上述可选方式的又一种变形，如图8所示，所述开阀机构包括抵顶部280,所述抵顶部280的一端与踏杆250的一端铰接，另一端可相对污水桶上下移动抵顶阀杆260上远离阀体220的一端以驱使阀杆260转动。踏杆250在外 力的作用下驱使抵顶部280向上移动并顶起阀杆260上远离阀体220的一端，从而打开阀体220并排出清洗腔中的污水。该实施例中，用户同样可以免手操作，实现电动拖把清洗过程和脱干过程的切换。
作为本实施例中的其他可选方式中，该电动拖把清洗装置的开阀机构可以通过电子方式或无线方式进行控制，来实现阀体的开闭。例如，开阀机构包括电磁铁和顶杆，顶杆由电磁铁驱动而顶开阀体，从而排出清洗腔中的污水。本领域人员可以理解，本申请中揭示了多种阀体和开阀机构相互配合工作的机械结构，它们均可以搭配相适应的电子或无线控制方式，以实现控制阀体开闭的功能。
实施例二：
本实施例为在前述实施例基础上的进一步优化改进，至少提升清洗装置的自动化程度，提升用户的使用体验。
结合图9至18所示，本实施例中，所述清洗装置200还包括可转动的阀杆260，所述阀杆260至少部分设于清洗腔内，所述阀杆260包括驱动端260b和从动端260c，阀体220设于阀杆的从动端260c，阀杆的驱动端260b与擦头抵接，清洁转盘反转时擦头带动阀杆260转动以打开所述漏水孔。
所述电动拖把100的自动清洗过程包括：
清洗步骤：所述清洁转盘带动擦头正转并刮蹭清洗部件231，以清理附着于擦头上的污物；
排水脱干步骤：所述清洁转盘反转并驱动阀杆260上的阀体220打开所述漏水孔211，擦头旋转刮蹭清洗部件以脱水。
其中，所述“正转”和“反转”是相对的概念，并不限制具体的转动方向。具体地，所述“正转”为顺时针旋转，所述“反转”为逆时针旋转；或者，所述“正转”为逆时针旋转，所述“反转”为顺时针旋转。
在本实施例中，所述清洁转盘包括主机左侧的第一转盘和主机右侧的第二转盘，所述阀杆260可对应于第一转盘或第二转盘设置。以所述阀杆260对应所述第一转盘设置为例，所述第一转盘反转时擦头带动阀杆260转动以打开所述漏水孔，所述第一转盘正转时，阀杆260的驱动端260b受到擦头水平方向的力使其向封闭漏水孔的方向移动在封闭漏水孔后阀杆相对擦头打滑使得阀体进一步压紧封闭漏水孔。清洗时第一转盘正转，阀杆260的从动端260c的 阀体封闭漏水孔，转盘转动时擦头与清洗腔内的清洗用水接触并与清洗部件旋转刮蹭从而将附着于擦头上的污物清除；清洗完成后第一转盘反转，擦头带动阀杆转动从而自动打开漏水孔，将污水排出清洗腔，擦头同时旋转刮蹭清洗部件以脱水。在整个过程中，直接通过转盘正反转驱动与擦头抵接的阀杆控制漏水孔的开闭，用户无需手动参与排水，实现了清洗的自动化，提升用户体验。
作为本实施例中一种实施方式，所述主机内设有两个电机，所述两个电机的输出轴分别与所述第一转盘和第二转盘连接。如此，所述两个转盘的转向可以分别控制，可以实现当一个转盘转动时，另一个转盘停止；也可以是当一个转盘正转时，另一个转盘反转等等，从而满足用户的实际需要。
优选的，在所述排水脱干步骤中，所述第一转盘反转，所述第二转盘正转。由于在排水脱干过程中，第二转盘并不参与控制漏水孔的开闭，通过将其设置为保持正转，能够简化控制逻辑，更加方便控制。
作为本实施例中另一种实施方式，所述清洗装置200还包括水箱(图中未示出)，在所述自动清洗过程中，所述清洗步骤之前还包括注水步骤，通过所述水箱向所述清洗腔内注水。通过在清洗装置上设置水箱，在清洗之前通过水箱向清洗腔内自动供水，从而进一步减少用户的手动参与，提升自动化程度。
优选的，所述阀杆260整体位于清洗腔内，所述阀杆260与清洗桶210转动连接。具体的，所述清洗腔的内底壁上设有凸起的阀座213，所述阀杆260与阀座213枢转连接。
在本实施例的一种可选方式中，如图18(图中未示出清洗部件)所示，所述阀杆260的枢转中心轴与水平面大致垂直以使阀体220水平方向移动打开或者关闭漏水孔。
优选的，在本实施例中，所述阀杆的枢转中心轴与水平面大致平行以使阀体上下方向移动打开或者关闭漏水孔。
本实施例中，所述阀杆的驱动端260b穿过所述清洗机构230上的过水孔230b并高于所述清洗部件231。具体的，如图13所示，所述阀杆的驱动端260b与清洗部件231的顶端之间的距离H范围5～15mm。
在本实施例的一种可选方式中，所述阀杆260与清洗机构230枢转连接。
结合图9至13，在本实施例的一种方式中，所述清洗装置200具有经过所述枢转中心轴o-o并与水平面垂直的第一平面，所述阀杆260的驱动端260b 和从动端260c位于所述第一平面的异侧。具体的，所述阀杆的驱动端的动力臂与从动端的阻力臂之间的夹角为钝角。
优选的，结合图14至16，在本实施例中，所述清洗装置200具有经过所述枢转中心轴o-o并与水平面垂直的第一平面，所述阀杆260的驱动端260b和从动端260c位于所述第一平面的同侧。当拖把放置在清洗装置上时，所述阀杆的驱动端与擦头抵接受到向下的力，使得所述阀体能够更好地封闭漏水孔。此外，还使得阀杆的整体重心也位于靠近漏水孔一侧，在未放置电动拖把时其自身能够受重力作用而复位封闭漏水孔，结构简单可靠。
在本实施例中，所述转盘的底面设有用以固定擦头的魔术贴，所述阀杆的驱动端和擦头的抵接位置至少部分位于转盘转动时魔术贴经过路径所形成的环状区域内。所述转盘带动擦头转动时，阀杆的驱动端与擦头抵接，可能会使擦头部分与转盘底面的魔术贴分离，造成擦头固定不牢，进而影响清洗效果。在本实施例中，将阀杆的驱动端和擦头的抵接位置设置在与转盘转动时魔术贴经过路径所形成的环状区域至少部分重叠，使得转盘转动时，阀杆的驱动端向上抵压所述擦头，从而将擦头牢固的固定在转盘的底部，保证清洗效果。
当拖把未放置在清洗装置上时，需要保持阀体封闭所述漏水孔，使得用户在使用之前可以径自向清洗腔中添加清洗用水，为此，还在所述清洗桶上设置阀杆260的复位构件以在清洗完成时能够自动复位至所述漏水孔被封闭的位置。
在本实施例的一种方式中，所述阀杆260的复位构件具体为扭簧214，所述扭簧214设于所述阀座213上，用于在清洗完成时使阀杆复位至所述漏水孔被封闭的位置。
在本实施例的另一种方式中，阀体220上设有第一导磁体(图中未示出)，所述清洗桶靠近漏水孔区域设有第二导磁体(图中未示出)，第一、第二导磁体磁极相反以使阀杆260回复以封闭所述漏水孔。具体的，所述第一导磁体封闭安装于所述阀体的内部，所述第二导磁体封闭安装于清洗桶的内部，从而避免导磁体外露而造成污损，提高使用可靠性。
在本实施中，所述阀杆260的枢转中心轴o-o经过所述对应的清洁转盘的转动中心轴，即，所述阀杆260的枢转中心轴o-o与所述清洁转盘的转动中心轴相交。如此，使得所述阀杆转动时的整个力臂和阀杆与擦头抵接位置到转动 中心的线段垂直，从而减少驱动阀杆转动时的其他方向的分力损失，提高漏水孔打开的可靠性。
进一步地，如图17所示，本实施例中的漏水孔211处还可以设有环形的密封圈215，所述密封圈215的外周与漏水孔211固定，所述密封圈215的内周设有厚度向中心方向逐渐变小并向中心方向延伸的凸缘215a，所述阀杆260上的阀体220封闭漏水孔211时，阀体220的底面与所述凸缘215a抵接，从而能够实现更好的封闭密封。
基于前文的描述，本领域技术人员能够理解的是，本实施例的擦头在正转时能够被清洗桶内的清水浸湿，并被清洗部件反复刮蹭，实现清洗；在反转时能够通过擦头带动阀杆转动，开启清洗桶底部的漏水孔，使清洗桶内脏污的水排出，进而使清洗部件将擦头吸附的污水刮除脱干。
实施例三：
在本实施例中，主要对前述实施例中的清洗机构230进行优化以改进电动拖把的清洗效果。
结合图19至22所示，本实施例中的清洗部件231包括呈曲线形的清洗筋232。优选地，所述清洗筋232分为两组，所述两组清洗筋232分别与所述两个清洁转盘相对应。所述每组清洗筋的内法线方向与相应的清洁转盘的转动方向相同。如图19所示，位于主机左侧的清洁转盘沿着图中带箭头的虚线路径顺时针转动，位于主机右侧的清洁转盘沿着图中带箭头的虚线路径逆时针转动。
为了实现对待清洁表面进行清洁，擦头的清洁表面上设有紧密排布且具有一定长度的纤维，在清洁过程中，脏污会逐渐在擦头的清洁表面上聚集并逐渐嵌入至纤维之间而难以清洗。在本实施例中，通过在清洗部件上设有内法线方向与清洁转盘的转动方向一致的曲线形清洗筋，使得擦头在对清洗筋刮蹭过程中，擦头上的纤维受曲线型清洗筋的阻挡而有效地疏散开来，藏纳于纤维之间尤其是纤维根部的污物能够被容易地冲洗和刮擦后脱离擦头，从而将擦头清洗干净。此外，由于擦头上的纤维被有规律的松散开，能够避免擦头上的纤维相互缠绕导致阻尼增大而烧毁电机，保证电机的工作可靠。
需要说明的是，在本实施例中，所述清洗筋可以是如图19、20所示连续的条状，也可以是如图21所示的多段组合而成的，还可以是如图22所示的凸点组合形成的。
可选的，所述每组清洗筋的内端延伸交汇至中心位置和/或每组清洗筋的内端延长线交汇至中心位置。可以理解地，所述中心位置为清洗部件231上与该组清洗筋相应的清洗转盘的转动中心对应的位置，所述内端是指所述清洗筋靠近所述中心位置的一端。优选的，在本实施例中，所述每组清洗筋包括第一清洗筋232a,所述第一清洗筋232a的内端延伸交汇至所述中心位置，所述清洗筋包括第二清洗筋232b，所述第二清洗筋232b内端的延长线交汇至所述中心位置，所述第一清洗筋232a与第二清洗筋232b周向交替且相对于所述中心位置对称布置。
通过将清洗筋的内端设置为延伸交汇至中心位置和/或清洗筋的内端延长线交汇至中心位置，使得擦头在旋转清洁过程中，每转过一定角度范围内所述清洗筋的有效长度最长，从而使刮蹭清洗作用最大化，提升清洗的效果。
电动拖把在清洁过程中，不可避免的会黏附有毛发，而这些毛发通常都依附缠绕在擦头的纤维头部，如若不能对其进行去除将会导致纤维无法有效的疏散。
进一步的，所述清洗筋232的上表面设有凸起部。优选的，所述凸起部是凸点。
通过在所述清洗筋的上表面设置凸起部，使得清洗时擦头上的毛发会被挂在凸起部上而脱离擦头，以方便后续的纤维根部清洁。
可选的，所述清洗部件包括内环壁233与外环壁234，内环壁233与外环壁234通过清洗筋232连接，内环壁233、外环壁234和清洗筋232之间形成镂空的过水孔230b。
如此，使得所述清洗筋与内环壁、外环壁交错形成网状的结构，清洗部件的整体强度更好，而且内环壁、外环壁和清洗筋之间形成的呈镂空状的过水孔面积大，清洗过程中污物能够及时有效地通过过水孔，提升清洗效率。
进一步的，所述内环壁233的上表面低于外环壁234的上表面。内环壁233的上表面与外环壁234的上表面存在高度差，使得擦头中间区域能够更容易与水接触并吸水，并在清洁转盘转动过程中向擦头外部扩散，形成较为规则的从内向外的循环清洁水路，更容易将擦头上的污物清理下来，提升清洗效果。
可选的，所述清洗机构上还包括内法线方向与清洁转盘转动方向相反的曲线形清洗筋和/或放射状的直线形清洗筋。通过设置多种类型的清洗筋，使得 在清洗过程中，擦头上的纤维周期性的在不同类型的清洗筋表面刮蹭，脏污可以被多个方向上的力刮蹭脱离而使擦头被清洗干净。
实施例四：
在本实施例中，主要对前述实施例中的清洗机构230进行优化以改进电动拖把的清洗效果。
结合图23至26所示，本实施例中的所述清洗机构230可拆卸的架设于清洗腔中，清洗机构230的底部设有凹槽235，所述凹槽235的开口朝下以在清洗腔内水位漫过时形成有封闭的空气。优选的，所述凹槽235至少对应设置在清洗部件231的下方。
本实施例中，通过将清洗机构可拆卸地架设在清洗腔中，并在清洗部件底部设置开口朝下且低于溢水孔的凹槽，使得需要对电动拖把进行清洗时，向清洗桶内进水并使清洗腔内的水位逐渐升高并漫过凹槽的口部时，会将原本位于凹槽内的空气压缩并封闭于其中，清洗部件在封闭空气的浮力和电动拖把重力的双向作用下变得相对不稳定，当清洁转盘产生上下摆动时，清洗部件跟随清洁转盘产生动态的上下浮动，从而使清洗部件可以始终紧贴清洁转盘上的擦头，提升清洁效果和效率。其次，由于凹槽内空气的存在，使得清洗腔内的污水与凹槽的接触面积小，减少由于水中的污物黏附在凹槽内而产生的卫生死角，更有利于用户清洁清洗部件。再次，对电动拖把清洗的过程中，清洗桶和清洗部件的表面不可避免的黏附有脏污，通过将清洗桶与清洗部件分体可拆卸设置，可以减少不便清洁的死角，方便用户对清洗桶进行清洗。
优选的，在本实施例中，如图26所示，所述凹槽235的开口低于所述溢水孔212的下沿且两者之间的的高度差为H1，所述清洗部件231的顶端低于所述溢水孔212的下沿且两者之间的高度差为1～8mm，这样，清洗部件的上部会始终处于清洁用水之中以使擦头始终与清洁用水接触。
进一步的，所述凹槽235为多个且互不连通。如此，使得各凹槽之间相互独立，避免在清洗过程中某一凹槽形成的气封失效而导致所有气封都失效。
具体的，所述第一清洗筋232a的交汇中心处也设有抵接部236，所述抵接部236抵接在清洗桶的底壁以此增强清洗部件在支承电动拖把时的强度和清洗时的工作稳定性。
实施例五：
本实施例中，主要对前述实施例中的清洗桶210进一步改进优化。
结合图27至29所示，本实施例中的清洗腔包括与所述清洁转盘分别对应的转盘腔，所述转盘腔左右布置且大致呈圆形，所述转盘腔包括左转盘腔和右转盘腔，所述排水口211设置于左转盘腔和右转盘腔交界区域的清洗桶的底部，左转盘腔和右转盘腔交界区域的清洗桶210前端桶壁和/或后端桶壁上设有向漏水孔方向内凸的扰流部216，所述扰流部216在排水时阻扰清洁转盘121转动形成的偏心液流。优选的，如图28中所示，左侧的清洁转盘顺时针转动，右侧的清洁转盘逆时针转动，图中虚线箭头表示清洁转盘的转动方向，实线箭头表示液流的流动方向。
电动拖把清洁完地面后，放置于清洗桶的清洗腔内，向清洗桶内添加适量清洗用水并使清洗用水至少部分漫过清洗部件，以使电动拖把上的擦头能够与清洗用水接触，启动清洗模式后电机驱动清洁转盘转动，清洁转盘带动擦头旋转并刮蹭清洗部件上的清洗筋以清理附着于擦头上的脏污。可以理解的，清洗时也可以是先向清洗桶内添加适量清洗用水并使清洗用水至少部分漫过清洗部件，再将电动拖把放入清洗腔。
清洗时，电动拖把的擦头转动带动清洗桶内的水流形成旋转的液流，从擦头上脱离的污物扩散至液流中并随液流运动。清洗完成后，清洁转盘停止转动并将漏水孔打开，液流会在一段时间内继续旋转，由于离心力的作用，液流在流经两转盘腔交界区域时会发生分散形成多股液流并向远离圆心一侧偏流减速，污物会随这些分散的偏心液流流经漏水孔并排出，但也会有部分污物来不及从漏水孔排出而跃过漏水孔后继续向下游运动，由于扰流部向漏水孔方向内凸并靠近漏水孔，当这部分液流与扰流部相遇撞击而产生向漏水孔侧运动的回流而从漏水孔排出，进而提升清洗桶的排污效果,减少污物沉积黏附在清洗桶内。
优选的的，清洗桶210前端的桶壁和后端的桶壁上同时设有所述扰流部216，所述扰流部设有相对设置的阻扰面216a以对电动拖把形成限位，所述阻扰面216a之间设一限位柱237，所述电动拖把的主机底部设有与限位柱237相对应的限位槽(图中未示出)。优选的，所述限位柱237设置在清洗机构230上。
优选的，所述溢水孔212设于清洗桶210桶壁上的与扰流部216连接的过 渡面上。由于清洗桶架设在污水桶的口部，使得清洗桶的周壁与污水桶的周壁之间的距离较小，导致溢水时水流阻力较大而影响溢水速度，通过将溢水口设于桶壁上的与扰流部连接的过渡面上，能够以最少数量的溢水口实现较快的溢水速度。
相比于现有技术中在清洗桶中设置两个限位柱对电动拖把进行定位的方式，本实施例中通过设置一个限位柱以限制减少主机在水平面上左右移动，通过设置一对相对设置的阻扰面以限制减少主机在水平面上前后晃动，并且将限位柱设置在两个阻扰面相对的区域范围内，使得限位柱的定位点位于两阻扰面之间，用户在放置电动拖把时，无论是以限位柱为基准还是以阻扰面为基准都能够方便、快速地实现定位，而且定位区域面积大，定位可靠，保证电动拖把清洗时稳定，进而提升清洗效率。
进一步的，所述扰流部216设有朝向排水口211延伸的扰流筋217，所述扰流筋217的一端与阻扰面216a连接，另一端向排水口221方向延伸，所述扰流筋217低于清洗部件231。优选的，所述阻扰面正对排水口设置，且所述阻扰面的宽度大于排水口的直径。
通过设置低于清洗部件的扰流筋，而且所述扰流筋从阻扰面向排水口方向延伸，增加阻扰的面积同时还缩短了阻扰的路径，使得位于液流中部和底部的相对较重的污物能够更多地被撞击后折返或者沉积在排水口附近，更容易被排出。
以上实施例仅用以说明本发明的技术方案，而非对其限制。尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换，而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
