详述
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例， 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作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明，本申请实施例中所有方向性指示(诸如上、下、左、右、前、后……)仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
另外，在本申请中如涉及“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本申请的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
在本申请中，除非另有明确的规定和限定，术语“连通”、“固定”等应做广义理解，例如，“固定”可以是固定连通，也可以是可拆卸连通，或成一体；可以是机械连通，也可以是电连通；“连通”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或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
另外，本申请各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
本申请实施例提出了一种水箱，包括水箱本体，水箱本体设有盛液腔、第一风道和第二风道，盛液腔构造出污水腔和清水腔，清水腔、污水腔和第二风道在水箱本体的轴向上依次设置，第一风道包括相连通的输送段和出口段，输送段位于水箱本体的安装侧、并沿盛液腔的轴向延伸；其中，出口段的出口和第二风道的入口均位于污水腔的远离安装侧的区域内、并均与污水腔连通，且出口段的出口和第二风道的入口在盛液腔的周向上依次设置。
该水箱应用于洗地机，水箱安装在洗地机的机身上，地刷安装在机身的一端，第一风道的入口与地刷连通，第二风道的出口与风机组件连通，安装侧朝向机身，第一风道的出口和第二风道的入口均位于污水腔内远离安装侧的区域内，且出口段的出口和第二风道的入口在盛液腔的周向上依次设置，这样出口段的出口和第二风道的入口距离安装侧的距离可以设计至最大，洗地机的机身进行大角度倾斜时，污水腔内的污水的液面更好地位于第一风道的出口和第二风道的入口的下方，液面不会到达第一风道的入口和出口段的出口，液面不会自第一风道的出口向第一风道回流，也不会自第二风道的入口流入第二风道。
本申请实施例还提供了一种表面清洁设备，包括设有风机组件的机身、地刷和上述任一实施例所述的水箱，水箱安装在机身上，地刷安装在机身的一端，第一风道的入口与地刷连通，第二风道的出口与风机组件连通，安装侧朝向机身。
该表面清洁设备，具备上述任一实施例提供的水箱的全部优点，在此不再赘述。
本申请实施例提出了一种水箱，包括：设有盛液腔的水箱本体，盛液腔内设有分隔壁，分隔壁的边缘连接在盛液腔的周壁上，且分隔壁设有安装口；和柔性的分隔件，沿盛液腔的轴向布置、并密封安装在安装口处，分隔件和分隔壁共同将盛液腔分隔成容积可变的清水腔和污水腔。
该水箱，分隔件固定方式简单，水箱制造成本低，而且分隔件在盛液腔内位置固定，分隔件与分隔壁仅要求在安装口处密封，很容易实现，在分隔件不损坏的情况下，清水腔和污水腔在分隔件处不会出现泄漏的问题，水箱也不会出现被划伤的问题。
其中，分隔壁可以设置为折形板，折形板结构简单、容易制作。
本申请实施例还提供了一种表面清洁设备，包括机身和上述任一实施例所述的水箱，水箱安装在机身上。
该表面清洁设备，具备上述任一实施例提供的水箱的全部有点，在此不再赘述。
本申请实施例提供了一种水箱，包括水箱本体，水箱本体设有盛液腔、第一风道和第二风道，盛液腔构造出污水腔和清水腔，清水腔、污水腔和第二风道在水箱本体的轴向上依次设置，第一风道包括相连通的输送段和出口段，输送段位于水箱本体的安装侧、并沿盛液腔的轴向延伸；其中，出口段的出口和第二风道的入口均位于污水腔的远离安装侧的区域内、且均与污水腔连通。
该水箱应用于洗地机，水箱安装在洗地机的机身上，地刷安装在机身的一端，第一风道的入口与地刷连通，第二风道的出口与风机组件连通，安装侧朝向机身，第一风道的出口和第二风道的入口均位于污水腔内远离安装侧的区域内，洗地机的机身进行大角度倾斜时，污水腔内的污水的液面位于第一风道的出口和第二风道的入口的下方，不会自第一风道的出口向第一风道回流，也不会自第二风道的入口流入第二风道。
本申请实施例还提供了一种表面清洁设备，包括设有风机组件的机身、地刷和上述任一实施例所述的水箱，所述水箱安装在所述机身上，所述地刷安装在所述机身的一端，所述第一风道的入口与所述地刷连通，所述第二风道的出口与所述风机组件连通，所述安装侧朝向所述机身、所述第二侧背向所述机身。
本申请实施例提供的表面清洁设备，具备上述任一实施例提供的水箱的全部优点，在此不再赘述。
如图2至图13所示，本申请实施例提供了一种应用于洗地机的水箱，包括水箱本体100和柔性的分隔件200，水箱本体100设有盛液腔、第一风道110和第二风道120，分隔件200的边缘直接连接或间接连接在盛液腔的周壁上、并将盛水腔分隔成容积可变的清水腔130和污水腔140，清水腔130和污水腔140位于第一风道110的同一侧，而且清水腔130、污水腔140和第二风道120沿第一风道110的延伸方向依次设置，第一风道110的出口与污水腔140的远离清水腔130的一端连通，第二风道120的入口与污水腔140的远离清水腔130的一端连通。第一风道110的延伸方向为自第一风道110的入口向第一风道110的出口的方向。
该技术方案，分隔件200固定方式简单、容易实现、成本低，而且分隔件200在盛液腔内位置固定，在分隔件200不损坏情况下，清水腔130和污水腔140在分隔件200处不会出现泄漏的问题。
在一些示例中，如图2至图5、图7至图13所示，水箱本体100的第一风道110所处的一侧为水箱的安装侧300，水箱本体100的清水腔130和污水腔140所处的一侧为水箱的第二侧400，安装侧300和第二侧400为相对侧，第二风道120的入口远离安装侧300、临近第二侧400。该水箱应用于洗地机，水箱安装在洗地机的机身510上，水箱的安装侧300朝向洗地机的机身510，清水腔130位于污水腔140和洗地机的地刷520之间，第一风道110的入口朝向地刷520，第二风道120的出口背向地刷520、并与过滤器和机身510上的风机组件530配合使用，风机组件530包括罩体和安装在罩体内的电机等部件。洗地机在工作时清水腔130内的水被渐渐消耗，分隔件200朝向清水腔130变形，清水腔130的体积逐渐减小，污水腔140的体积逐渐增大，污水沿着第一风道110自第一风道110的出口进入污水腔140，污水腔140内的液面会更低，洗地机的机身510大角度倾斜下污水腔140内的污水也始终处于第二风道120的入口的下方，污水腔140内的污水不会自第二风道120的入口进入第二风道120，也就不会沿第二风道120经过过滤器进入风机组件内损坏电机，因此该洗地机可以实现对床体下方和柜体下方等低高度空间进行清洁。
在一些示例中，如图3至图5、图7、图8和图13所示，第一风道110的出口自安装侧300向第二侧400延伸至污水腔140内(可以是，第一风道110包括相连通的输送段11和出口段112，输送段111沿盛液腔的轴向布置，出口段112位于污水腔140内，出口段112自输送段111沿污水腔140的径向延伸而使出口段112的出口远离安装侧，第一风道110通过出口段112与污水腔140连通)，第二风道120的入口位于污水腔140的远离清水腔130一端的端壁上，第一风道110的出口和第二风道120的入口之间通过隔板150分隔开，第一风道110的出口朝向隔板150，第一风道110的出口和隔板150之间构造出第一折流段610，洗地机的机身510在倾斜状态下能够保证第一风道110的出口处于污水腔140内液面的上方，既可以避免机身510 大角度倾斜下污水腔140内的污水自第一风道110的出口沿第一风道110回流，还可以避免(自第一风道110的出口经过污水腔140向第二风道120的入口运动的)气流将污水腔140内的污水吹起并沿第二风道120吹送至风机组件530内，造成电机遇水损坏的问题。
可以是，如图3至图5、图7和图8所示，第一风道110的出口和第二风道120的入口在第一方向依次布置，第一方向为自安装侧300向第二侧400所处的方向；或者可以是，如图9A所示，第一风道110的出口和第二风道120的入口在第二方向上依次设置，第二方向与第一方向垂直，而且第二方向与清水腔130的远离污水腔140的端壁平行等的方式；以上均可实现本申请的目的，其宗旨未脱离本申请的设计思想，在此不再赘述，均应属于本申请的保护范围内。
在一些示例中，如图5所示，隔板150设有第一阻挡壁151，第一阻挡壁151横置在第一风道110的出口外、并与第一风道110的出口相间隔、且遮挡第一风道110的出口，第一折流段610的出口和第一阻挡壁151之间构造出第二折流段620，这样可以防止第一风道110的出口吹出的气流直接吹向污水腔140内的污水液面而引起污水飞溅；污水腔140内设有第二阻挡壁141，第二阻挡壁141横置在第二风道120的入口外、并与第二风道120的入口相间隔、且遮挡第二风道120的入口，第二风道120的入口和第二阻挡壁141之间构造出第三折流段630，这样可以更好地阻止污水腔140内飞溅的污水经过第二风道120的入口进入第二风道120内。
可以是，隔板150为直板(图中未示出)；或者可以是，隔板150为异形板(如图3至图5、图7和图8所示)等，异形板能够更好地阻挡自第一风道110进入污水腔140内的污水，使得污水更好地沿异形板在重力作用下流向污水腔140内；以上均可实现本申请的目的，其宗旨未脱离本申请的设计思想，在此不再赘述，均应属于本申请的保护范围内。
可以是，如图3至图6、图8所示，分隔件200与盛液腔相连接位置所处的平面相对于清水腔130的远离污水腔140的端壁平行设置；或者可以是，如图7所示，分隔件200的边缘所处的平面相对于清水腔130的远离污水腔140的端壁垂直设置，采用的技术方案如盛液腔内设有折形板160，折形板 160包括两个横板161和一个竖板，两个横板161位于竖板的两侧、并通过竖板相连接，竖板上设置有安装口，安装口位于两个横板161之间，分隔件200固定安装在安装口处，分隔件200和折形板160将盛液腔分隔成清水腔130和污水腔140，水箱应用于洗地机，两个横板161中的一个临近风机组件530、远离地刷520，两个横板161中的另一个临近地刷520、远离风机组件530；或者可以是，分隔件200与盛液腔相连接位置所处的平面相对于清水腔130的远离污水腔140的端壁倾斜设置，如：分隔件200沿第一风道110的延伸方向(可以理解为：自下向上)自第二侧400向安装侧300倾斜，如图13所示，倾斜角度θ可以是15度至60度，此方案洗地机正常工作时，机身510与地面形成一定夹角，分隔件200更趋向于水平，这样分隔件200与污水腔140内的液面的夹角很小，可以有效提升污水腔140朝向清水腔130一端的有效容积，使得污水腔140内液面与第二风道120的入口之间的距离更大；或者如分隔件200沿第一风道110的延伸方向自安装侧300向第二侧400倾斜(此方案图中未示出)，倾斜角度可以是15度至60度，此方案洗地机正常工作时，污水腔140最低点更低、呈倒三角形，倒三角形结构增大了污水腔140的容积，污水腔140可以盛装更多的污水，而且污水腔140内液面与第二风道120的入口之间的距离也更大；以上均可实现本申请的目的，其宗旨未脱离本申请的设计思想，在此不再赘述，均应属于本申请的保护范围内。
在一些示例中，如图3至图6、图8和图13所示，分隔件200与盛液腔相连接位置所处的平面相对于清水腔130的远离污水腔140的端壁平行设置或倾斜设置时，参见图8，分隔件200的边缘与清水腔130的远离污水腔140的端壁之间的距离为L1，盛液腔在第一风道110的延伸方向上的高度为L2，在L1/L2>0.5时，污水腔140的容积不足；在L1/L2<0.25时，清水腔130的容积不足，因此将L1/L2设置为0.25至0.5。对于分隔件200与盛液腔的周壁相连接的位置所处的平面相对于盛液腔的轴线倾斜设置的结构，分隔件200与清水腔130的远离污水腔140的端壁之间的距离L1设置为分隔件与清水腔130的远离污水腔140的端壁的最大距离和最小距离的平均值。对于分隔件200连接在折形板160上的方案，两个横板161与清水腔130的远离污水腔140的端壁的之间的距离的平均值为L1，盛液腔在第一风 道110的延伸方向上的高度为L2，L1/L2设置为0.25至0.5。
清水腔130装满水，清洁初始阶段，洗地机的机身510处于倾斜状态，分隔件200朝向污水腔140内凸起形成凸包170(分隔件设有凸起结构，水挤压凸起结构形成凸包170)，凸包170倚靠在安装侧300，致使污水腔140的朝向清水腔130的一端的临近安装侧300的第一区域191被凸包170大范围充满而难以容纳污水，污水存储在污水腔140的朝向清水腔130的一端的临近第二侧400的第二区域192，该第二区域192与第二风道120的入口距离更近，自第一风道110的出口进入污水腔140内的气流容易将第二区域192的污水吹起，使污水自第二风道120的入口沿第二风道120吹送至风机组件530内，造成电机遇水损坏。如图5所示，可以在第一区域191设置支撑结构，支撑结构可以是间隔设置的多个支撑筋180，通过支撑筋180支撑起凸包170，这样相邻支撑筋180之间就形成了容纳污水的空间，确保污水能够大量的存储在第一区域191内，此时第二区域192的污水很少、且与第二风道120的入口距离较远，自第一风道110的出口进入污水腔140内的气流在向第二风道120的入口运动的过程中，不会将第二区域192的污水吹起，也就不会出现污水自第二风道120的入口沿第二风道120吹送至风机组件的问题，能够更好地避免电机遇水损坏，随着清水腔130内水的减少，凸包170会逐渐消失，分隔件200向清水腔130内变形，使得污水腔140的容积增大，污水腔140内的液面也会降低。
可以是：如图5和图6所示，在安装侧300，多个支撑筋180沿水箱本体100的周向间隔设置，每个支撑筋180沿水箱本体100的轴向延伸，任一支撑筋180的凸起高度可以设置为自远离分隔件200的一端向临近分隔件200的一端逐渐减小；或者可以是，在安装侧300，多个支撑筋180沿水箱本体100的轴向间隔设置，每个支撑筋180沿水箱本体100的周向延伸(此方案图中未示出)，多个支撑筋180的凸起高度可以设置为自远离分隔件200的一端向临近分隔件200的一端依次减小，且任一支撑筋180均为圆弧凸筋；以上均可实现本申请的目的，其宗旨未脱离本申请的设计思想，在此不再赘述，均应属于本申请的保护范围内。
在一些示例中，分隔件200设置为柔性的隔膜片，隔膜片以可替换的方 式进行安装，这样在隔膜片损坏时，用户可以自行更换隔膜片。
柔性隔膜的材质可以是氯丁橡胶、丁晴橡胶、聚四氟乙烯或聚全氟乙烯等，均可实现本申请的目的，其宗旨未脱离本申请的设计思想，在此不再赘述，均应属于本申请的保护范围内。
在一些示例中，如图3至图5所示，清水腔130的远离污水腔140的一端设有出水阀131和加水盖132。
在一些示例中，如图9A至图11所示，水箱本体100包括桶体101和盖体102。输送段111位于桶体101的侧壁上，盖体102盖装在桶体101的开口处，第二风道120和出口段112均位于盖体102上。其中，桶体101和盖体102共同合围成第一风道110和盛液腔；水箱本体100设计成分体结构，更容易制作和清洁。
在一些示例中，如图9A至图11所示，盖体102包括内盖103和外盖104。内盖103置于桶体101的开口内，出口段112和第二风道120的入口(见图10和图11中a位置)均位于内盖103上，外盖104盖装在桶体101的开口处，外盖104和内盖103共同合围成第二风道120。
在一些示例中，如图9A至图11所示，第二风道120的入口设置为两个，出口段112的出口设置为一个。在盛液腔的周向上：一个出口段112的出口(见图9A和图11中b位置)位于两个第二风道120的入口(见图10中a位置)之间，且出口段112的出口相对于第二风道120的入口朝向污水腔内凸起、并构造出环形壁105(或弧形壁)，环形壁105使得第二风道120的入口和出口段112的出口被分隔开、并形成落差，这样污水腔内的液体更不容易到达第二风道120的入口。图9A和图11中，c位置为出口段112的入口，出口段112的入口与输送段111的出口连通。
本申请实施例还提供了一种洗地机，如图12和图13所示，包括地刷520、与地刷520连接的机身510和上述任一实施例所述的水箱，水箱安装在机身510上，第一风道110的入口与地刷520连通，第二风道120的出口与机身510上的风机组件530连通，风机组件530包括具有出风口的罩体和安装在罩体内的电机等部件。
该洗地机，具备上述任一实施例提供的水箱的全部优点，在此不再赘述。
在一些示例中，罩体和第二风道520的出口之间设有过滤器(图中未示出)，过滤器设置成滤除自第二风道520吹向罩体的气流中的脏污，从而对罩体内的电机进行更好地防尘保护。
综上所述，本申请技术方案中，水箱应用于洗地机，水箱安装在洗地机的机身上，地刷安装在机身的一端，第一风道的入口与地刷连通，第二风道的出口与风机组件连通，安装侧朝向机身，第一风道的出口和第二风道的入口均位于污水腔内远离安装侧的区域内，且出口段的出口和第二风道的入口在盛液腔的周向上依次设置，这样出口段的出口和第二风道的入口距离安装侧的距离可以设计至最大，洗地机的机身进行大角度倾斜时，污水腔内的污水的液面更好地位于第一风道的出口和第二风道的入口的下方，液面不会到达第一风道的入口和出口段的出口，液面不会自第一风道的出口向第一风道回流，也不会自第二风道的入口流入第二风道。
如图14至图16所示，图14、图15显示了本实施例中的一种表面清洁装置的水箱1000。该表面清洁装置(即表面清洁设备)可以是洗地机。该水箱1000包括箱体1和污水管16-1，箱体1可设置成包括顶板11、底板12和侧板13。顶板11位于底板12的上方。污水管16-1构造出输送段。
顶板11和底板12可以构造为平板结构。侧板13设置在顶板11和底板12之间。侧板13可以是筒形，顶板11和底板12分别覆盖在侧板13的上、下两端。顶板11、底板12和侧板13围合出箱体1。箱体1的内腔内设置有隔膜2(相当于前文中提到的分隔件)，如图15所示，一个隔膜2将箱体1的内腔分隔成两个腔室，即位于上方的第一腔室14(即污水腔)，以及位于下方的第二腔室15(即清水腔)，隔膜2构成第一腔室14的底壁，构成第二腔室15的顶壁。也可在箱体1内设置两个以上的隔膜2。隔膜2处于顶板11和底板12之间，其边缘连接于侧板13的内壁。隔膜2在箱体1内的布置形式，可以是如图15所示的上下式，也可以是前后式，还可以是倾斜式等。
顶板11和底板12可以是平行于水平面的板体，侧板13可以是竖直设置的板体。如图15所示，第一腔室14的横截面可以设置成矩形或圆柱形等。第一腔室14用来容纳污物，包括污水和垃圾。第二腔室15设置成容纳清洗 液体，清洗液体可以是清水或者水溶液。该水溶液可以是清水与清洗剂的混合液。水箱1000实现了集清、污箱体的一体化设计，使得安装有该水箱1000的表面清洁装置的结构更加紧凑、外形更加小巧，存放空间更小。
在表面清洁装置工作时，从第二腔室15输出清洗液体以用来清洁地面。将第一腔室14设置在箱体1内靠上的位置，方便清理堆积在第一腔室14内的污物，使得水箱1000在整体布置上更合理，更符合人机操作舒适性的设计要求。
第一腔室14的顶壁上设置有出气口11-1。即出气口11-1设置在顶板11上，且与第一腔室14相连通。该出气口11-1外接于负压源，负压源可以是真空泵或风机。负压源启动时，第一腔室14内的气体从出气口11-1抽出。第二风道的入口即为出气口11-1。
第一腔室14的侧壁上设置有开口。开口位于第一腔室14的侧壁靠近第一腔室14的顶壁的一端。开口贯穿第一腔室14的侧壁，即贯穿侧板13。
污水管16-1设置在箱体1的一侧。污水管16-1从第二腔室15的外侧延伸到第一腔室14的外侧。污水管16-1靠近第一腔室14的一端连接到第一腔室14的开口。污水管16-1靠近底板12的一端设置有污物入口。
在负压源启动时，第一腔室14内形成负压，污物与气体的混合物从该污物入口进入污水管16-1，并通过污水管16-1排入到第一腔室14内。
第一腔室14和第二腔室15均设置在箱体内，第一腔室14设置成容纳污物，第二腔室15设置成容纳清洗液体，污水管16-1从第二腔室15的外侧延伸到第一腔室14的外侧。这样，表面清洁装置可以仅设置一个水箱1000就既能容纳清洗液体，也能容纳污物，且污水管16-1位于箱体1的外侧，这种水箱1000的结构更加简单，第一腔室14的容积也能更大。
在一个示意性实施例中，污水管16-1可以构造为直条形，且竖直设置在箱体1的一侧。
污水管16-1竖直设置可以使得污水管16-1的长度尽可能短，污物流经污水管16-1时的阻力较小，污物也不容易在污水管16-1内发生气液分离使得污水沿着污水管16-1的管壁向下流动。
在一个示意性实施例中，污水管16-1从靠近底板12的位置延伸到靠近顶板11的位置。即，污水管16-1从第二腔室15背离第一腔室14的一端延 伸到第一腔室14背离第二腔室15的一端。
污水管16-1朝上延伸到第一腔室14背离第二腔室15的一端，第一腔室14内的污物不容易从第一腔室14内返流到污水管16-1内并从污水管16-1流出。
在一个示意性实施例中，污水管16-1的管壁与侧板13连接在一起，污水管16-1与箱体一体成型。污水管16-1和箱体可以是采用注塑工艺制成。
污水管与箱体一体成型可以减小零件数量，降低装配成本，同时也能增加污水管与箱体的结构强度。
在一个示意性实施例中，污水管16-1设置在箱体1的侧板13上，侧板13的一部分构成污水管16-1的管壁。即，污水管16-1靠近箱体1的管壁为箱体1的侧板13的一部分。
污水管16-1与箱体1共用一个侧板13作为各自的壁面可以减少原材料的消耗，同时，污水管16-1的内部流道与箱体1的内腔之间仅隔了一层侧板13，水箱1000整体更加紧凑。
在一个示意性实施例中，如图15所示，侧板13包括第一侧板13-1和第二侧板13-2，第一侧板13-1和第二侧板13-2均构造为筒形。第一侧板13-1靠近顶板11，第二侧板13-2靠近底板12。第一侧板13-1背离顶板11的一端连接于第二侧板13-2背离底板12的一端。
箱体1还包括直条板161a，直条板161a设置在侧板13外。直条板161a与侧板13围合出污水管16-1。直条板161a包括第一直条板161a1和第二直条板161a2。
第一直条板161a1设置在第一侧板13-1上，第二直条板161a2设置在第二侧板13-2。第一直条板161a1和第二直条板161a2相连接。第一直条板161a1和第一侧板13-1围合出一个直流道，第二直条板161a2和第二侧板13-2围合出一个直流道，两个直流道的端部相接通而形成污水管16-1。
在一个示意性的实施例中，如图15所示，箱体1的第一腔室14内还设置有气液分离通道16-2。气液分离通道16-2的一端连接于第一腔室14的开口，并通过该开口与污水管相接通。气液分离通道16-2在第一腔室14内蜿蜒延伸。污水管16-1和气液分离通道16-2构造出第一风道。
气液分离通道16-2背离第一腔室14的开口的一端上设置有排污口 16-4。在负压源启动时，污物与气体的混合物进入气液分离通道16-2后，气液分离通道16-2进行气液分离，气液分离通道16-2中的污物从排污口16-4排入到第一腔室14内。
在本实施例中，气液分离通道16-2设置在第一腔室14内且靠近顶板11，气液分离通道16-2的一部分与第一腔室14的顶壁相抵。气液分离通道16-2的一端与污水管16-1靠近顶板11的一端相连通。气液分离通道16-2为弯曲的通道。排污口16-4设置在气液分离通道16-2不与污水管16-1相接的一端。污物和气体的混合物从污水管16-1输入到气液分离通道16-2内后，流经气液分离通道16-2时发生气液分离，再从排污口16-4排入到第一腔室14内。
气液分离通道16-2包括第一段16-3和第二段16-5。第二段16-5设置在第一腔室14内，第二段16-5一端连接于污水管16-1靠近顶板11的一端。第二段16-5沿着第一腔室14的顶壁延伸。第一段16-3可设置成沿顶板11向着第一腔室14的顶壁中部位置延伸。第一腔室14的顶壁为箱体1的顶板11。第二段16-5设置在第一段16-3靠近底板12的一侧。第二段16-5的一端与第一段16-3背离污水管16-1的一端相接通，排污口16-4设置在第二段16-5的另一端上。第一段16-3与第二段16-5之间可以弯转180°。污物从第一段16-3进入到第二段16-5后需要进行180°的转向，由于惯性的作用污物甩在气液分离通道16-2的内表面，污物从夹带污物的气体中分离出来，气液分离效果好。
在第一腔室14内盛有污物后，在水箱1000竖直放置时，污物的液面至少要达到与气液分离通道16-2位置最高部分的高度相同时才能从气液分离通道16-2流出第一腔室14。而在本水箱1000内，由于一部分气液分离通道16-2抵靠第一腔室14的顶壁，即第一段16-3与第一腔室14的顶壁相抵靠，污物的液面至少要达到接近第一腔室14的顶壁的位置才能通过气液分离通道16-2流出第一腔室14，否则即便污物的液面没过排污口16-4，污物进入到排污口16-4，污物也难以通过气液分离通道16-2流出第一腔室14。由于污物的液面至少要达到接近第一腔室14的顶壁才能通过气液分离通道16-2流出第一腔室14，此时污物几乎灌满了第一腔室14，因此该第一腔室14的有效容积大。
一部分气液分离通道16-2抵靠第一腔室14的顶壁至少包括以下两种情 形：可以是如图15所示第一腔室14的顶壁构成一部分气液分离通道16-2的管壁；也可以是将气液分离通道16-2设置在一根管道内，该管道的一部分外壁与第一腔室14的顶壁相抵。
在一个示意性的实施例中，第一段16-3连接第二段16-5的一端位于第一腔室14的顶壁的中部。
在使用表面清洁装置清洁地面时，水箱1000会向着操作者的一侧倾斜，即便污水从排污口16-4进入到第二段16-5内，污物的液面没过第一段16-3连接第二段16-5的一端才能从通过气液分离通道16-2流出第一腔室14，因此，即便在水箱1000倾斜时，污物也难从气液分离通道16-2流出，可有效降低第一腔室14内污物发生反流的概率。
在一个示意性的实施例中，如图15所示，第一段16-3和第二段16-5之间设置有一块隔离板，该隔离板的一端连接于侧板13。第一段16-3位于隔离板与第一腔室14的顶壁之间。第一段16-3和第二段16-5之间仅被隔离板隔开。排污口16-4靠近第一腔室14的顶壁。由于排污口16-4靠近第一腔室14的顶壁设置，第一腔室14内的污水难以进入排污口16-4。
在一个示意性的实施例中，如图15所示，排污口16-4朝向第一腔室14的侧壁，即朝向侧板13。在本实施例中，排污口16-4朝向靠近污水管16-1一侧的侧板13。
排污口16-4朝向第一腔室14的侧壁排出污物，污物和气体的混合物碰撞第一腔室14的侧壁后转向，污物和气体的混合物在转向时能将部分污物从气体中分离出来。
在另一个示意性的实施例中，排污口16-4还可以设置成朝向底壁。排污口16-4朝向底壁时便于将第一段16-3内的污水排净。
在一个示意性的实施例中，第一腔室14内还设置有挡板17，挡板17设置在第一腔室14的顶壁上，从顶板11向着底板12方向延伸。挡板17与隔膜2之间具有间隔。
出气口11-1设置在挡板17的一侧，气液分离通道16-2上的排污口16-4设置在挡板17的另一侧。排污口16-4可以是朝向挡板17。
污物和气体的混合物在经过气液分离通道16-2时进行第一次气液分离，然后从排污口16-4排放到第一腔室14内，由于出气口11-1与排污口16-4 之间设置挡板17，排放到第一腔室14内的气体需要绕过挡板17的底端才能从出气口11-1输出第一腔室14，在气流绕过挡板17时气流需要转向180°，一部分夹杂在气流中的小液滴会从气流中甩出来，因而再次进行气液分离，提升了排出气体的清洁度。
在一个示意性的实施例中，如图16所示，箱体1还包括导流板18-1和防水板18-2。导流板18-1设置在顶板11上。导流板18-1可设置成垂直于顶板11的板状结构。导流板18-1的一端连接于出气口11-1的边缘，导流板18-1的另一端向着靠近隔膜2方向延伸。防水板18-2的一端与导流板18-1背离顶板11的一端连接，防水板18-2向导流板18-1靠近出气口111的一侧伸出。防水板18-2垂直于导流板18-1。防水板18-2可设置成与顶板11平行。防水板18-2与侧板13的内壁之间存在间隔，即防水板18-2未抵接侧板13的内壁。这样，防水板18-2部分遮盖出气口11-1，防止第一腔室14内的污水飞溅到出气口11-1中。
在一个示意性的实施例中，隔膜2可设置为如图15所示的袋状结构，隔膜2具有柔性。隔膜2可以是塑料薄膜。隔膜2的边缘连接于侧板13的内周壁。
在水箱1000工作的初期，由于第二腔室15内所需要容纳的污物相对较少，可通过隔膜2向上凸出，使得第一腔室14容积较大、能容纳较多的清洗液体。随着工作时间增多，被储存到第二腔室15内的污物逐渐增多，而储存在第一腔室14内的清洗液也逐渐减少，在第一腔室14内的负压作用下隔膜2逐渐向下翻，第二腔室15的容积增加以便于容纳更多的污物。该隔膜2能使得水箱1000内的第一腔室14和第二腔室15的容积呈现“此消彼长”的变化，在水箱1000有限的容积下，结合水箱1000所处的不同工作状态，以及对两个腔室容积需求的不断变化，使得水箱1000内的空间得到合理化的利用。
可以理解的，隔膜2还可以设置成具有弹性的薄膜，例如，橡胶或者硅胶等，隔膜2在外力的作用下可弹性变形，具有弹性的隔膜的形状不限于袋状。这种隔膜2也可以使得水箱1000内的第一腔室14和第二腔室15的容积呈现“此消彼长”的变化。
在一个示意性的实施例中，隔膜2的表面还设置有防污涂层，该防污涂层可采用具有疏水性质的材质，例如，聚烯烃、聚碳酸酯、聚酰胺、聚丙 烯腈、聚酯、不含氟的丙烯酸酯、熔融石蜡等。也可选用具有疏油性质的材质，例如，聚四氟乙烯等。或者是，既有疏水性又具备疏油性质的材料，例如，聚四氟乙烯。防污涂层不利于污物吸附在隔膜2的表面，提高了隔膜2的耐脏性，降低了隔膜2的清洗成本。
在另一个示意性实施例中，污水管16-1与箱体1之间可以为分体设置。污水管16-1为独立于箱体1的侧板13的元件。污水管16-1可以设置成圆管或扁管。污水管16-1组装到箱体1上。污水管16-1与箱体1之间可以是可拆卸连接，例如螺纹连接。可以将第一腔室1的开口设置成螺孔，在污水管16-1的一端设置外螺纹，将污水管16-1的设置有外螺纹的一端拧入到第一腔室1的开口内以完成组装。污水管16-1与箱体1分体设置，在加工时可以分开加工，在完成加工后再组装到一起。
污水管16-1的管壁可以与箱体1的侧板13之间至少有一部分分隔开来，例如污水管16-1仅有与第一腔室14的开口14-1相连通的一端与侧板13相抵，污水管16-1的其他部分均与侧板13分开。
污水管16-1与箱体1也可以是相互抵靠在一起，污水管16-1靠近箱体1一侧的管壁完全贴合于箱体1的侧板13。
如图17所示，本实施例中的一种表面清洁装置，该表面清洁装置内设有上述任一示意性实施例中所述的水箱1000。
在一个示意性实施例中，表面清洁装置还包括机身510。水箱1000被设置于机身510的前侧，使得在使用表面清洁装置时，水箱1000朝上，以便于观察水箱1000内部第一腔室14内污物，以及第二腔室15内清水的水位情况。污水管16-1设置在水箱1000靠近机身510的一侧(即污水管16-1设置在水箱10的安装侧)。污水管16-1可以被机身510遮挡，以使得表面清洁装置更加美观。
如图18至图21所示，根据本申请的实施例，本申请提供了一种清洁装置(包括表面清洁设备)的水箱1000，为了方便对清洁装置以及水箱1000进行阐述，本申请通过洗地机以及洗地机内的尘杯状的水箱1000进行阐述， 水箱1000包括水箱本体，水箱本体包括容纳壳10、风机过滤盖30、导流管40和挡板50，容纳壳10的内部形成有污水腔20，容纳壳10的侧壁设置有连通污水腔20与清洁装置的污水的污水通道10-1(即输送段)，风机过滤盖30设置于容纳壳10的顶部，污水腔20的顶部形成有与风机过滤盖30连通的风道(即第二风道)，导流管40的进管口401设置成与污水通道10-1连通，导流管40的出管口402伸至风道、并向背离风机过滤盖30的方向弯曲，挡板50设置于污水腔20并至少部分位于导流管40的出管口402的下方，导流管40内的污水能够流至挡板50的下方。
本申请的水箱1000通过将导流管40的出管口402设置为向背离风机过滤盖30的方向弯曲，并通过挡板50的配合减少污水通过水箱1000的污水口流至风机过滤盖30以及风机的现象。可以是，容纳壳10的侧壁设置有与污水腔20隔开并沿容纳壳10的高度方向分布的夹层，污水通道10-1设置于夹层的内部，污水通道10-1的底部形成与清洁装置的污水连通的污水进口，污水通道10-1的顶部形成与风道连通的污水出口，将污水出口设置为与风道连通，可以降低污水从污水通道10-1流至污水腔20内的压力。此外，挡板50至少部分位于导流管40的出管口402的下方包括挡板50倾斜放置于污水腔20，此时，挡板50的较高部位位于出管口402的上方，挡板50的较低部位位于出管口402的下方。
再者，由于风道与风机过滤盖30连通，将污水出口设置为与风道连通，存在有从污水出口流出的污水在风道处被吸至风机过滤盖30和风机的风险，因此，本申请的实施例提出了通过导流管40对污水出口处的污水进行导流，使污水出口处流出的污水在导流管40的引导下向远离风机过滤盖30的方向流动，并通过挡板对污水的阻挡，减少污水出口流出的污水在风道处被吸至风机过滤盖30和风机的现象。
在一些示例中，容纳壳10为顶部具有开口的筒状结构，容纳壳10的横截面为圆形、封闭的弧形或者矩形中的任意一种，风机过滤盖30为顶部具有斜开口的筒状结构，风机过滤盖30通过按压的方式安装至容纳壳10的顶部开口处，且风机过滤盖30与容纳壳10的顶部开口之间设置有密封圈。
风机过滤盖30包括过盖体31和设置于盖体31的顶部的滤芯，风机过 滤盖30通过盖体31可拆卸地安装至容纳壳10的顶部开口处，盖体31的顶部设置有与风机连通的通风口301，风机通过风机过滤盖30抽取污水腔20内的风道处的空气，从而使污水腔20内形成负压，使清洁装置内的污水在负压作用下通过污水通道10-1流至污水腔20，滤芯可以减少固体垃圾堵塞风机口的现象，滤芯可以为HEPA(高效空气过滤器)，以此提高风机过滤盖30对固体垃圾的过滤效果。
如图18至图21所示，根据本申请的一个实施例，导流管40设置为L型扁管，L型扁管的第一段41与风机过滤盖30平行并靠近风机过滤盖30设置，L型扁管的第二段42与容纳壳10的侧壁平行。
在本实施例中，L型扁管的第一段41的宽度方向沿容纳壳10的径向尺寸分布，不仅可以提高污水在导流管40内的流通面积，还可以减少L型扁管占用污水腔20的轴向空间，降低导流管40对污水腔20内污水容积的影响。
进一步地，L型扁管的第二段42靠近容纳壳10的侧壁设置，将L型扁管的第二段42设置为靠近容纳壳10的侧壁设置，可以降低L型扁管的第二段42对容纳壳10内其他部件的影响，例如，当容纳壳10内设置有位于污水腔20的底部的柔性可膨胀的分隔件70时，分隔件70在向污水腔20内膨胀的过程中，分隔件70的中部向污水腔20内的膨胀变形量较大，分隔件70的周边向污水腔20内的膨胀变形量较小，为了减少分隔件70的中部向污水腔20内膨胀变形时与的第二段42分隔件70发生干涉现象，本申请的实施例提出了将L型扁管的第二段42设置为靠近容纳壳10的侧壁设置。
另外，L型扁管的第二段42设置于与导流管40的进管口401相对的一侧，且导流管40的第一段41覆盖了风机过滤盖30和风道的一部分，为了减少风道与风机过滤盖30之间的通风效果，本申请的实施例提出了将盖体31上的通风口301设置为避开导流管40并与风道连通。可以是，为了实现风机过滤盖30的通风均匀性效果，本申请的实施例提出了在盖体31上设置位于导流管40的两侧的通风口301，以此达到风机过滤盖30能够在导流管40的两侧进风，以及风机过滤盖30上的滤芯能够具有较大的有效过滤面积。
为了减少污水从通风口301处流至风机过滤盖30以及增加滤芯的有效 过滤面积，本申请的实施例还提出了将通风口301设置为由底部向顶部逐渐扩张的扩口结构，从而使从通风口301流出的空气能够附着在滤芯的较大过滤部位。
如图18至图21所示，为了进一步减少污水从通风口301处流至风机过滤盖30的现象，根据本申请的一个实施例，盖体31上设置有围绕盖体31的通风口301设置的护板302，护板302至少包括背对导流管40的进管口401设置的遮挡部。或者可以是，导流管40上设置有围绕盖体31的通风口301设置的护板302，护板302至少包括背对导流管40的进管口401设置的遮挡部；或者可以是，盖体31和导流管40上设置有围绕盖体31的通风口301设置的护板302，护板302至少包括背对导流管40的进管口401设置的遮挡部。
在本实施例中，护板302不仅可以减少导流管40的进管口401处的污水流入通风口301，还可以减少污水腔20内的污水流入通风口301，可以是，护板302至少包括背对导流管40的进管口401设置的遮挡部，以及背对导流管40的出管口402设置的连接部，遮挡部与连接部连接后形成角板结构，角板结构的遮挡部设置成阻挡导流管40的进管口401处的污水流入通风口301，角板结构的连接部设置成阻挡污水腔20以及导流管40的出管口402的污水流入通风口301。
如图18至图21所示，根据本申请的一个实施例，挡板50的一端设置于导流管40的进管口401的下方，挡板50的另一端向下倾斜并设置于导流管40的出管口402的下方。
在本实施例中，通过在污水腔20设置挡板50，能够有效的抑制高液位时的水面晃动，当污水液滴在气流的带动下向滤芯和风机口的移动过程中经过该挡板50时，污水液滴会被沉积在挡板50上，沉积在挡板50上的污水液滴进一步汇聚后回流至污水腔20的底部，以此增加风道处的空气干度，减少滤芯和风机口出现进水或者浸水的现象。
在一些示例中，挡板50倾斜布置在污水腔20的中上部位置，并与水平面呈0°至60°夹角，将挡板50设置为倾斜布置，一方面在容纳壳10内设置有位于污水腔20的底部的柔性可膨胀的分隔件70时，分隔件70在向污水 腔20内膨胀的过程中，分隔件70的中部向污水腔20内的膨胀变形量较大，分隔件70的周边向污水腔20内的膨胀变形量较小，倾斜布置的挡板50可以在分隔件70的中部向污水腔20内膨胀变形时避开分隔件70。
另一方面，在污水液滴在气流的带动下向滤芯和风机口的移动过程中经过该挡板50时，污水液滴会被沉积在挡板50上，沉积在挡板50上的污水液滴进一步汇聚后沿着挡板50的倾斜面回流至污水腔20的底部。
如图18至图21所示，进一步地，根据本申请的一个实施例，挡板50的另一端设置有与导流管40的出管口402配合的豁口51，导流管40内的污水能够通过豁口51流至挡板50的下方。
在本实施例中，挡板50一般位于污水液面的上方，或者挡板50的一端位于污水液面的上方，挡板50的另一端位于污水液面的下方。在挡板50的另一端位于污水液面的上方的情况下，挡板50的另一端设置的豁口51形成无阻碍的污水流道，使得污水能够在向污水腔20的底部的流动过程中不撞击的挡板50上，减少污水中的脏污沉积在挡板50上的现象。
可以是，如图18至图21所示，根据本申请的一个实施例，挡板50设置有多个通孔，本申请实施例中提供的挡板50的边沿轮廓与容纳壳10的内壁轮廓相同，且挡板50设置有多个通孔，挡板50还能够通过多个通孔将污水腔20的固体垃圾过滤在挡板50的下方，减少污水腔20的固体垃圾被吸至风机过滤盖30和风机口的现象。
进一步地，通过在挡板50上设置有多个通孔，不仅能够使导流管40流出的污水通过多个通孔流至挡板50的下方，而且，在污水腔20内的污水漫过挡板50时，挡板50下方的大量污水能够经过多个通孔的过滤后流至挡板50的上方，以此减少污水中的大量固体垃圾通过挡板50的豁口51流至挡板50的上方。
如图18至图21所示，进一步地，根据本申请的一个实施例，容纳壳10以倾斜方式放置于清洁装置，挡板50与容纳壳10的倾斜方向相同。
在本实施例中，在将容纳壳10以倾斜方式放置时，仍能使导流管40的出管口402露出污水外与风道连通，可以降低污水从导流管40的出管口402 流至污水腔20内的压力。进一步地，在将容纳壳10以倾斜方式放置时，污水腔20内的污水形成向导流管40的进管口401的方向倾斜的倾斜面，挡板50与污水液面的倾斜方向一致，从而使挡板50能够有效的抑制高液位时的水面晃动，污水液滴会被沉积在挡板50上并回流至污水腔20的底部，以此增加风道处的空气干度，减少滤芯和风机口出现进水或者浸水的现象。
如图18至图21所示，根据本申请的一个实施例，污水腔20形成于容纳壳10的顶部，容纳壳10的底部还设置有清水腔60，容纳壳10的中部设置有分隔污水腔20与清水腔60的分隔件70。
在本实施例中，本申请的洗地机的污水腔20和清水腔60仅需要一个容纳壳10的安装空间，进而可减小洗地机的整体体积，可降低整体的成本，并使得洗地机整体更为小巧。
如图18至图21所示，根据本申请的一个实施例，分隔件70设置有柔性隔膜，柔性隔膜能够在污水腔20内的污水作用力与清水腔60内的净水作用力的合力下上凸或者下凹。
在本实施例中，洗地机在工作时清水腔60的水被渐渐消耗，同时污水随着气流沿着污水通道10-1进入污水腔20，污水腔20的进水口以及污水通道10-1的污水出口设置在容纳壳10的顶部，容纳壳10在倾斜状态下能够使气道处的进气气流远离污水液面，减少进气气流将污水吹起的现象。
同时，容纳壳10配有形状可变的柔性隔膜，在清水腔的清水流出用于清洁后，能够将清水腔的内部空间逐渐分配给污水腔20，可以保证污水腔20的污水液面一直处于较低的高度并远离风机过滤盖30和风机口，保证容纳壳10大角度倾斜下污水不会到达风机过滤盖30和风机口。
本申请还提供了一种清洁装置，清洁装置包括上述任一实施例提供的清洁装置的水箱1000，容纳壳10以倾斜状态放置于清洁装置。
在本实施例中，清洁装置还可以为自移动拖地机器人或擦玻璃机器人中的一种，清洁装置在使用过程中清水腔60的净水被渐渐消耗，同时污水随着气流沿着污水通道10-1进入污水腔20，同时，容纳壳10配有形状可变的柔性隔膜，在清水腔的清水流出用于清洁后，能够将清水腔的内部空间逐渐 分配给污水腔20，可以保证污水腔20的污水液面一直处于较低的高度并远离风机过滤盖30和风机口，保证容纳壳10大角度倾斜下污水不会到达风机过滤盖30和风机口。
进一步地，污水腔20还包括浮子(图中未示出)，浮子可上下浮动地设置于污水腔20，浮子设置在污水腔20用来监测污水腔20的污水水位，清洁装置还包括控制器(图中未示出)和警报装置(图中未示出)，警报装置和浮子均与控制器电连接，控制器根据浮子监测到的污水水位值达到警戒值后启动警报装置，当污水腔20的水位达到警戒值后，浮子将污水腔20的水位信息发送至清洁装置的控制器，控制器启动警报装置提醒用户清理污水腔20，以此减少污水腔20积存大量的污水影响清洁装置的正常使用。
需要说明的是，本实施例只是对清洁装置上与本申请的改进点有关的结构进行了阐述，并不代表清洁装置不具备其他结构，例如，本申请实施例中的水箱1000还包括设置于容纳壳10以及清水腔60的底部的过滤底座80，过滤底座80设置有连通清水腔60与水机的过滤筒81，这些结构均属于本申请实施例的保护范围，在此不再进行详细赘述。
可以是，清洁装置为表面清洁装置；例如，表面清洁装置为洗地机。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
