具体实施方式
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详细地描述，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做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。
本申请实施例提供一种清洁机器人200，包括本体和水箱400，所述水箱400可拼接在所述清洁机器人200的本体上。
可以理解的是，清洁机器人200可以是扫地机器人、扫拖一体机器人、擦地机器人、擦窗机器人、手持式吸尘器或者手推清洁机等，在此不作限定。
清洁机器人200的本体230的形状不做限定，例如圆形、方形、椭圆形、三角形或者多边形等。本实施方式采用清洁机器人200的本体230的形状为圆形进行解释说明。
请参阅图1，所述清洁机器人200包括本体230，本体230可以包括底盘231和上盖组件232，上盖组件232可拆卸地安装于底盘231上，以在使用期间保护清洁机器人200内部的各种功能部件免受激烈撞击或无意间滴洒的液体的损坏；底盘231和/或上盖组件232用于承载和支撑各种功能部件。在一可选实施例中，清洁机器人200的本体230也可以是其他设计构造，例如，本体230为一体成型结构、左右分离设置的结构，本申请实施例对本体230的材料、形状、结构等不做限定。所述底盘231和所述上盖组件232之间形成所述内腔，所述内腔用于为所述清洁机器人200的内部器件提供排布空间。所述清洁机器人200可以在所述内腔中排布真空泵、电路板、地面检测传感器、碰撞检测传感器和沿墙传感器等。
所述清洁机器人200可以被设计成自主地在地面上规划路径，也可以被设计成响应于遥控指令在地面上移动。在本申请实施例中，所述清洁机器人200包括安装于所述底盘231上的行走机构，所述行走机构包括两个驱动轮500、至少一个万向轮600、以及用于带动轮子转动的马达，所述两个驱动轮500和所述万向轮600至少部分凸伸出所述底盘231的底部，例如，在清洁机器人200在自身重量的作用下，所述两个轮子可以部分地隐藏于底盘231内。在一可选实施例中，所述行走机构还可以包括三角履带轮、麦克纳姆轮等中的任意一种。
所述清洁机器人200可以包括清洁组件，所述清洁组件可拆卸连接于所述机器人200的本体230。所述清洁组件包括中扫组件和拖擦组件中的一个或两个。所述中扫组件包括至少一个中扫刷700，所述至少一个中扫刷700可以设于底盘231的底部开设的收容槽内，收容槽内开设有吸尘口，该吸尘口与集尘盒 以及吸尘风机连通，使得当中扫毛刷转动时将地面上的灰尘、垃圾搅起，利用吸尘风机产生抽吸力把灰尘、垃圾从吸尘口吸入至集尘盒内。
请参阅图1，图1示出了清洁机器人200的底部视角。清洁机器人200的本体230在底部安装有引水件210，引水件210设置有分流道，清洁机器人200上还安装有连通引水件210的抽水装置，抽水装置将水箱400内的液体抽向引水件210。分流道将流入引水件210的液体分流到引水件210的各个区域，以保证清洁机器人200在工作工程中，液体能够充分湿润整块拖布。
清洁机器人200的内部安装有风机。图1中F所指示的区域为安装区域，清洁机器人200的本体设置有对应安装区域的承载结构，承载结构可承载排布于安装区域内的风机。需要说明，该承载结构不一定设置在清洁机器人200本体的中部，还可以设置在旁侧。另外，该安装区域不限定安装风机，也可以安装清洁机器人200本体内的其他结构。由于承载结构的占位较大，水箱400需要配合清洁机器人200的本体230结构进行改进设置。清洁机器人200本体上还设置于至少部分包围所述承载结构的拼接槽，水箱400可拆卸地安装于所述拼接槽内，如图中S所指部分。
具体请参阅图2，图2示出了水箱400一种实施结构的示意图。水箱400的结构可以是一体结构，也可以是分体结构进行装配构成。分体设置例如，水箱400包括底板401和壳体402(如图5)，底板401和壳体402围合构成所述水箱400，水箱400的内部形成储水腔。如图2或图4b所示，水箱400包括与清洁机器人200本体进行装配的拼接侧P，以及与拼接侧P相对应的侧表面C，其余的两侧与清洁机器人200的上下方向对应。为了避让清洁机器人200的承载结构，水箱400的拼接侧P设置有朝向水箱400内部凹陷的让位区域R，当水箱400安装在清洁机器人200的本体上时，水箱400的拼接侧P与清洁机器人200的本体230拼接，让位区域R容纳清洁机器人200的本体230的承载结构。优选地，水箱400的侧表面C与所述清洁机器人200的本体230的侧表面平滑过渡，理解为清洁机器人200本体的侧表面和水箱400的侧表面C之间连续，使得整体结构更加紧凑和美观。另外，水箱400的侧表面C设置弧形，因此与清洁机器人200的本体230更为融合。
让位区域R的位置相对应清洁机器人200的承载结构设置，当承载结构设置在清洁机器人200的本体230的中部时，让位区域R也相应凹设在水箱 400的中部，当承载结构设置在清洁机器人200本体的旁侧时，让位区域R也相应凹设在水箱400的旁侧。另外，让位区域R的凹陷四周可以是连续壁面，或者让位区域R的顶部被贯穿呈敞口设置，或者让位区域R的底部被贯穿呈敞口设置。图2中，示出了让位区域R顶部呈敞口设置的方案。
请继续参阅图2，水箱400上还设置有加水口，加水口上通过胶塞件410进行封盖，用户可以通过取下胶塞件410后对水箱400进行加水。水箱400上还设置有出水阀420，前述清洁机器人200的抽水装置与该出水阀420接通，以对水箱400内的液体进行抽取。抽水装置包括抽水管220和水泵(如蠕动泵)，出水阀420具有出水管220道，抽水装置的抽水管220插入出水阀420的出水管220道内，触发打开出水阀420。为了提高出水阀420和抽水管220之间的密封性，可以在两者连接出设置有密封件。例如，在抽水管220的四周套上密封塞，当抽水管220插入出水阀420的出水管220道时，密封塞过盈配合在出水管220道内。另外，抽水管220和出水阀420之间的配合，可以提高水箱400安装在清洁机器人200本体上的稳定性和牢固性。
请参阅图2和图3，让位区域R的设置，使得水箱400大致划分为三个区域，包括中部较窄中部区域N和两边较宽的旁侧区域M。相应的，水箱400内的储水腔形成位于所述让位区域R相对两侧的两主储水腔430，以及对应所述让位区域R设置且连通两所述主储水箱400的副储水腔440。两侧的主储水腔430的储水空间均比副储水腔440的储水空间大，因此该设置结构的水箱400在包含两个大容积的主储水腔430前提下，保证水箱400足够大的储水量的同时，还起到让位效果。
进一步的，请参阅图4a和图4b，图4b为图4a中的水箱400沿I-I线的截面视图，所述副储水腔440包括纵向储水空间441和横向储水空间442，所述纵向储水空间441邻近所述让位区域R的侧部，所述横向储水空间442邻近所述让位区域R的底部，所述纵向储水空间441的横截面宽度大于所述横向储水空间442的横截面宽度。容易理解的，由于所述承载结构的高度尺寸较大，让位区域R也需要设置较大的高度尺寸，让位区域R的底部接触承载结构的底部，若将横向储水空间442的截面宽度设置较大，则所述水箱400的高度尺寸将进一步增加，导致清洁机器人200的整体高度增加，且所述横向储水空间442过大容易导致所述水箱400底部的强度不足，容易压倒障碍物而损坏。 但是，让位区域R的下方未设置有横向储水空间442，则水箱400的容水量相对降低。同时，对于纵向储水空间441而言，不需要占用水箱400的高度尺寸，也不存在容易被压坏的问题，所以将横向储水空间442的截面宽度设置较小，而相对将纵向储水空间441的截面宽度设置较大进行弥补，旨为最大程度提升水箱400的储水量。
下面对横向储水空间442的形成进行描述。在一种实施方式中，设置水箱400包括包括底板401和壳体402，如图5，所述壳体402安装在所述底板401上以与所述底板401围合形成水箱400的储水腔。其中，底板401可以是平板设置；或者，底板401包括平板以及围设在平板周围的围板，平板和围板之间形成有位于平板上方储水空间；或者，底板401由平板设置，平板的上板面下凹形成有储水空间；更或者，底板401包括平板和设置在平板周围的结构件，平板和结构件围合有位于平板上方的储水空间。当底板401为平板设置时，横向储水空间442由安装在底板401上的壳体402围成，当底板401自带储水空间时，横向储水空间442则由所述储水空间的部分或者全部构成。
请参阅图4c，所述底板401具有对应所述让位区域R的最低水位区域Q 1和与所述最低水位区域Q 1邻接的倾斜导流区域Q 2，所述水箱400包括设置于所述底板401的最低水位区域Q 1的引水机构450。引水机构450通过导管与出水阀420相连通，引水机构450将水引至出水阀420。进一步的，所述最低水位区域Q 1与所述让位区域R正对设置，为了提升集水的效果，在最低水位区域Q 1的周边设置有与所述最低水位区域Q 1邻接的倾斜导流区域Q 2，所述倾斜导流区域Q 2用于将两个所述主储水腔430和所述副储水腔440的水引导至所述最低水位区域Q 1上，由此提高所述引水机构450的集水效果。
请参阅图3，副储水腔440在水平方向上的正投影面积大于主储水腔430在水平方向上的正投影面积。在保证水箱400的强度前提下，将主储水腔430的集水面积设置较大，提升集水空间。
在另一实施例中，两所述主储水腔430的水平宽度在朝向靠近所述副储水腔440的方向上逐渐减小。当中，水平宽度可以是水箱400在水平投影上的长度方向的宽度，也可以是水箱400在水平投影上的宽度方向的宽度。具体的，举例水平宽度为水箱400在水平投影上的长度方向进行解释，请继续参阅图3，主储水腔430在水平的方向上具有宽度L，让位区域R设置后，主储水腔430 的水平宽度朝向靠近所述副储水腔440的方向上逐渐减小。该设置，实现了让位区域R具有较大的容积，有利于容纳较大体积的承载结构，从而实现水箱400和清洁机器人200的本体230的合理搭配，还有效保证了水箱400具有足够大的储水空间。
在另一实施例中，请参阅图6，所述让位区域R具有邻近所述水箱400底部设置的底壁a，以及连接所述底壁a而背离所述水箱400底部延伸的侧壁b。底壁a与侧壁b之间的连接呈圆滑过度，以当水箱400与清洁机器人200配合时，两着之间的接触面更加贴合。另外，圆滑过度的转角在产品生产时，更容易脱模。
进一步的，为了提高底壁a的支撑强度，优选地，在底壁a的下方设置有支撑件，支撑件Z一端与底壁a连接，另一端支撑在水箱400的底部。可以理解的，在支撑件Z的设置下，对底壁a进行支撑，提高了底壁a的承重能力，避免底壁a在碰撞或者承重时，容易产生损坏的问题。
对于安装加强件460的设置方式，和安装位置不做具体限定。例如，安装加强件460可以是安装筋、安装条、安装扣或者更多。安装加强件460的设置位置可以在水箱400上的任何位置，优选靠近水箱400的上部。在本申请中，优选的方案请参阅图6和图7，安装加强件460设置为加强筋，加强筋的延伸方向要配合水箱400安装至清洁机器人200时的移动方向。加强筋位于水箱400的上部，水箱400安装上清洁机器人200后，加强筋可以对水箱400起到固定作用的同时，还对水箱400的上部起到稳固作用，防止清洁机器人200在工作时，水箱400由于安装不牢固而出现晃动的问题。
进一步的，可以节省空间，同时不影响到让位区域R的设置，所以优选在让位区域R的侧壁设置有凹陷部470，凹陷部470靠近水箱400的拼接侧P并且贯穿出所述水箱400的拼接侧，将安装加强件460设置在凹陷部470内。优选的，在让位区域R的两侧都设计有所述凹陷部470，并且，两所述凹陷部470内都设置有所述安装加强件460。
请继续参阅图6，为了方便水箱400与清洁机器人200之间的安装配合，在所述水箱400的拼接侧P上设置有导向安装块480，所述导向安装块480对水箱400的安装起到导向作用。所述导向安装块480在起到导向作用除外，当水箱400安装至清洁机器人200本体后，导向安装块480相应固定在清洁机器 人200的本体230的安装槽内，起到防晃动的作用。在本申请中，优选设置有多个导向安装块480，如2块、4块、6块或者更多。图1中示出了设置2块导向安装块480的实施例的示意图，两所述导向安装块480分别位于让位区域R的两侧，并且两所述导向安装块480对称分布。
进一步的，为了方便导向安装块480的装配，以及方便水箱400的安装，优选设置所述导向安装块480的横截面积在远离所述水箱400的拼接侧P的方向上逐步减小。例如，导向安装块480大致呈梯形设置，或者呈三角形设置，或者呈半椭圆设置。
本申请技术方案所公开的水箱400中，水箱400的拼接侧P朝向水箱400的中部凹陷的让位区域R，该让位区域R可以对清洁机器人200的结构进行让位，避免对清洁机器人200的结构造成影响。其次，水箱400的让位区域R旁的结构具有较大容积的储水腔，由此保证水箱400的储水功能。此外，当水箱400安装至清洁机器人200后，水箱400的拼接侧P两端的侧表面C与所述清洁机器人200的本体230的侧表面平滑过渡，使得两者配合后的整体结构更加融合、紧凑及美观。
在本说明书的描述中，参考术语“第一个实施例”、“第二个实施例”、“本申请的实施例”、“一个实施方式”、“一种实施方式”、“一个实施例”、“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。
以上所述的实施方式，并不构成对该技术方案保护范围的限定。任何在上述实施方式的精神和原则之内所作的修改、等同替换和改进等，均应包含在该技术方案的保护范围之内。
