具体实施方式
为了使得本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
附图中各个部件或结构并非严格按照比例绘制，为了清楚起见，可能夸大或缩小各个部件或结构的尺寸，但是这些不应用于限制本公开的范围。为了保持本公开实施例的以下说明清楚且简明，可省略已知功能和已知部件的详细说明。
随着现代科技的不断进步，智能家居的理念成为引领时尚的潮流，随之适用于智能清洁的各种清洁装置层出不穷。对此，本公开的发明人发现，市场上清洁装置(例如，擦窗机，扫地机器人等)大致分为两类，一类是双圆盘扭动行进的组合模式，即：双圆盘的其中一圆盘与待清洁面相对转动，从而起到擦拭作用，而另一圆盘与待清洁面相对静止，其缓慢转动可以带动擦拭的圆盘绕其转动行进，直到下一周期，相对静止的圆盘与擦拭的圆盘互换角色，从而扭动行进。另一类擦窗机是采用双履带行进的组合模式，在履带四周可以固定一圈擦拭布，行进过程中擦拭布与待清洁面相对滑动从而将其擦拭。
然而，对于双圆盘扭动行进的组合模式，清洁装置的行进速度较慢，并且在双盘的不断切换过程中实现行进和清洁，清洁效率低下；双履带行进的组合模式，仅通过履带四周固定的一圈擦拭布进行清洁，其清洁效率低于带有转动的擦盘与清洁面接触擦拭的模式，通常无法彻底将清洁面清洁干净，清洁效果不佳。
本公开的实施例提供一种下壳组件和清洁装置。下壳组件包括：下壳本体、第一模组和第二模组，下壳本体包括底部和侧部，底部包括相对的第一侧和第二侧，侧部围绕所述底部设置以形成在底部的第一侧的凹腔；第一模组安装在底部的第二侧；第二模组安装在 底部的第二侧，与第一模组间隔设置，其中，所述第一模组被配置为围绕旋转轴线转动，所述第二模组被配置为围绕垂直于所述旋转轴线的轴线转动，所述旋转轴线沿所述第一侧指向所述第二侧的方向延伸。
本公开至少一实施例提供的用下壳组件及清洁装置，可以将清洁装置的清洁效果与行进速度结合，既包括能够实现清洁装置快速直线行进的模组，又包括能够通过旋转进行清洁的模组，在保证清洁装置的移动速度的同时，显著提高了清洁装置的清洁效率，进而使得清洁装置具有良好的清洁性能。
下面通过一些实施例对下壳组件及清洁装置进行说明。
图1A为本公开的一实施例提供的一种清洁装置的整体结构示意图。图1B为本公开的一实施例提供的一种用于清洁装置的局部结构示意图。图1C为本公开的一实施例提供的一种用于清洁装置的上壳的结构示意图。图1D为本公开的一实施例提供的一种用于清洁装置的整体示意图。图2为图B中的清洁装置沿A-A的剖视图。
参考图1A和图2，清洁装置1包括壳体组件01，该壳体组件01包括下壳组件10、中盖20以及上壳30。下壳组件10包括：下壳本体100、第一模组630以及第二模组640，下壳本体100包括底部600和侧部610，底部600包括相对的第一侧601和第二侧602，侧部610围绕底部600设置以形成在底部600的第一侧601的凹腔603；第一模组630和第二模组640安装在底部600的第二侧602，并且第二模组640与第一模组630间隔设置，第一模组630被配置为围绕旋转轴线678转动，第二模组640被配置为围绕垂直于旋转轴线678的轴线转动，旋转轴线678沿第一侧601指向第二侧602的方向延伸。例如，第一模组630可以相对于底部600绕旋转轴线678旋转；例如，第二模组640可以到单独驱动清洁装置1进行直线运动。
参考图1A和图2，下壳本体100的第一侧601上可以设置多种配合与安装结构，以满足清洁装置1中的各类部件进行安装与匹配，例如，清洁装置1中的各类部件可以设置于凹腔603中以实现相应的器件功能。例如，各类部件可以包括驱动电机14、电池组15、主控制板23、驱动器24，例如，主控制板23上设有控制模块，控制模块被配置为驱动清洁装置1；驱动器24可以作为清洁装置1的驱动控制元件；上壳30上还可以设置有喷嘴31、按键32、指示灯33、装饰件36，且装饰件36上包括水箱胶塞35和水箱底壳34。下壳组件10还包括罩壳部12，罩壳部12沿其周边与下壳本体100可拆卸连接。例如，在罩壳部12中，可设置清洁装置1的行走部件296或行走部件296的驱动部件297。
参考图1A和图2，第一模组630被配置为围绕旋转轴线678转动，第二模组640被配置为围绕垂直于旋转轴线678的轴线转动，二者通过相互配合，进而可以实现清洁装置1的直线行走及转弯，同时第一模组630能够通过旋转进行清洁，即在保证清洁装置1的移动速度的同时，显著提高了清洁装置1的清洁效率，进而使得清洁装置1具有良好的清洁性能。
图3A为本公开的一实施例提供的下壳组件中下壳本体的结构示意图。图3B为本公开的一实施例提供的下壳组件中下壳本体的另一视角的结构示意图。
参考图2、图3A和图3B，底部600包括第一安装部631和第二安装部641，第一安装部631为底部600的对应于第一模组630的部分，第二安装部641为底部600的对应于第二模组640的部分，侧部610具有远离底部600的结合面611，第一安装部631与结合面611之间的距离L1小于第二安装部641与结合面611之间的距离L2以使得第一安装部631和第二安装部641之间具有高度差ΔL。
例如，第一模组630可以通过紧固件安装在第一安装部631，并同时满足第一模组630能够相对于清洁装置1旋转。例如，在本公开的一些实施例中，第一安装部631可以包括旋转连接轴，第一模组630可以从中心处固定在该旋转连接轴上，并可以随着旋转连接轴旋转。例如，紧固件可以是螺栓，或者其他任何可以实现将第一模组630在第一安装部631上旋转固定的元件，本公开的实施例对此不作限制。
例如，第二模组640可以通过卡接、插接等方式连接在第二安装部641上，并能够随清洁装置同时行进。本公开对于第二模组640和第二安装部641的连接方式不作限制。
参考图2、图1C、图3A和图3B，结合面611位于侧部610远离底部600的一侧，该结合面611可以实现与上壳30的对接配合，使得上壳30中的对接面690与结合面611重合，从而为清洁装置1中的部件提供遮盖及保护。
例如，当第一安装部631与结合面611之间的距离L1小于第二安装部641与结合面611之间的距离L2，并使得第一安装部631和所述第二安装部641之间具有高度差ΔL时，第二安装部641比第一安装部631更贴近于待清洁面，当行走部件296与待清洁面的距离一定时，则第二安装部641将行走部件外露的高度Z相对减小。当第二模组640通过对行走部件296进行结构避让而安装于第二安装部641后，可以进一步对行走部件296的外露表面进行遮蔽。更进一步地，当第二模组640上设置有清洁件，例如清洁抹布时，清洁抹布可以将第二模组640包裹，进一步减少行走部件296的外露部分，使得清洁装置1的底部更具美观性。
参考图1A、图2和图3A，下壳组件10还包括罩壳部12，第二模组640包括清洁架642和行走部件296，底部600包括第一开口606以安装行走部件296和罩壳部12，罩壳部12安装在底部600上并被配置为容纳行走部件296的一部分，清洁架642具有第二开口607，以避让行走部件296。
例如，罩壳部12可以通过固定件固定在底部600的第一侧601，例如，可通过螺栓固定连接，以及其他任何可实现固定连接的合适方式，本公开对此不作限制。例如，罩壳部12内可以容纳行走部件296的一部分，以及行走部件296的驱动部件297，行走部件296的一部分设置在底部600的第一侧601，另一部分通过第一开口606伸出至底部600的第二侧602。驱动部件297设置在底部600的第一侧601，与行走部件296相邻，并被配置为驱动行走部件296沿行走方向带动清洁装置1行进。
例如，清洁架642上的第二开口607的开口面积大于底部600的第一开口606的开口面积。第二开口607可以为行走部件296提供避让空间，以使得行走部件296能够在待清洁面上转动；此外，第二开口607还可以为清洁装置1提供吸风入口，使得气流可以从清 洁装置1的底部经第二开口607吸入。
图4为图2中的清洁装置中第二模组的局部放大示意图。
参考图2、图3B和图4，清洁架642设有双层筋条648，底部600设有双层筋条647，清洁架642上的双层筋条648均呈环形并在其间形成凹槽650，底部600上的双层筋条647均呈环形并在其间形成凹槽649，清洁架642上的双层筋条648和底部600上的双层筋条647插接设置。例如，清洁架642和底部600通过双层筋条648和双层筋条647通过插接的方式设置，可以避免清洁架642相对于底部600在垂直于方向N的方向移动，造成清洁架642产生晃动，影响清洁装置的控制效果。方向N为垂直于双层筋条647或双层筋条648中的筋条的延伸方向。
例如，清洁架642和底部600上进行插接配合的筋条的数量可以相同，也可以不相同，本公开对此不作限制。同时，本公开对清洁架642和底部600上进行插接配合的筋条的数量也不作限制。例如，清洁架642上的筋条可以是一个，底部600上的筋条可以是两个，两者也能够实现筋条间的插接配合，例如，清洁架642或底部600上的筋条也可以包括多个，从而使得插接配合处的强度增强。
参考图2和图4，下壳组件10中的底部600在第二侧602具有延伸导向部651，其中，延伸导向部651的高度为M1，双层筋条647中每个筋条的高度为M2，且延伸导向部651的高度M1小于底部600上的双层筋条647中每个筋条的高度M2，以使得清洁架642和底部600之间具有移动空间652并使得清洁架642在高度方向N上具有移动量M3，底部600上的双层筋条647和清洁架642上的双层筋条648为清洁架642在高度方向上移动提供导向。其中，高度方向N为双层筋条647或双层筋条648的延伸方向，且各筋条的高度均为在高度方向N上的高度。
例如，清洁架642在高度方向N上具有移动量M3，可以减小清洁装置1的装配误差，以及与待清洁表面之间的匹配误差。当清洁装置1进行清洁操作时，第一模组630和第二模组640分别与待清洁面的匹配面需保持高度一致，即二者与清洁面的匹配面无高度差，以保证与清洁表面之间的充分接触。因此，当清洁装置1存在装配误差或零件设计误差，导致第一模组630和第二模组640与待清洁面的匹配面高度不一致时，清洁架642可以在移动空间652内朝方向N通过双层筋条648进行移动。例如，移动量M3的数值大小可以按照实际设计要求而定，本公开对此不作限制。
参考图2和图4，下壳组件10中的延伸导向部651位于底部600上的双层筋条647的外侧，清洁架642上的双层筋条648包括筋条6481和筋条6482，其中，筋条6481设置在底部600的双层筋条647之间的凹槽649中，清洁架642上的双层筋条648中的筋条6482设置在延伸导向部651和底部600的靠近该延伸导向部651的筋条6472形成的凹槽653内。
例如，延伸导向部651的延伸方向与双层筋条647或双层筋条648一致，从而可为清洁架642通过双层筋条648在移动空间652内移动时提供导向，避免清洁架642在垂直于方向N的方向上移动，有利于提升吸附效果。
参考图2和图4，底部600在第二侧602还设有密封筋条654，密封筋条654位于底部600上的双层筋条648的内侧，密封筋条654和底部600上的双层筋条648中的靠近该密封筋条654的筋条6481形成容置空间以容纳密封件655，延伸导向部651的高度M1小于密封筋条654的高度M4。
参考图2和图4，密封件655被配置为可被压缩，密封件655的高度M5大于双层筋条647和双层筋条648中的任一个的高度并大于密封筋条654的高度M4。
例如，密封件655的设置可以防止从第二开口607吸入的气流从双层筋条647和双层筋条648的配合间隙中漏出，起到密封作用，以保证清洁装置1的吸附强度。同时，密封件655的高度M5大于双层筋条647和双层筋条648中的任一个的高度，即密封件655的高度M5大于双层筋条647的高度M2，且大于双层筋条648的高度M6，并大于密封筋条654的高度M4，可以保证清洁架642在高度方向N上具有移动量M3，并且，密封件655的设置可以为清洁架642朝向靠近底部600的方向移动时，对清洁架642提供移动缓冲作用，避免清洁架642与底部600之间的相对运动时发生撞击或磨损，损坏器件。
例如，密封件655可以采用泡棉及任何可以挤压和密封的材料，本公开对此不作限制。
如图2所示，底部600在第二侧602设有限位柱656，清洁架642上设有限位孔657，限位柱656和限位孔657配合以使得清洁架642和底部600通过紧固件相连。例如，限位柱656上可以设置紧固件，而紧固件与限位孔657之间无连接，清洁架642在紧固件的限位作用下，通过紧固件卡在底部600上而不致朝远离底部600的方向脱落。同时，紧固件设置于限位柱656上后，清洁架642在限位孔657处可以进行移位，移位行程可以为Y。例如，移位行程Y可以与清洁架642的移动量M3相同。例如，紧固件可以是螺栓，或任何可满足上述装配需求的零件，本公开对此不作限制。
图5A为图1D中的清洁装置沿B-B的剖视图。
参考图1A、图2和图5A，下壳组件10还包括中盖20，中盖20位于底部600的第一侧601，并安装在底部600上，中盖20和底部600之间设有风腔658，底部600的第二安装部642具有吸附孔659，限位柱656和限位孔657的配合处与风腔658通过吸附孔659连通以使得限位柱656和限位孔658的配合处作为泄气孔。例如，紧固件的尺寸大小将满足限位柱656和限位孔657的配合后存在一定间隙，使得气流可以从该间隙中流通。
参考图1A和图5A，下壳组件10还包括风机21和出风罩22，中盖20设有凹陷660，凹陷660中设有进风口204，风机21位于出风罩22和中盖20的凹陷660之间，出风罩22与中盖20的凹陷660的周边密封连接，下壳本体100和中盖20之间的空间形成风腔658。
例如，当风机21运行时，从进风口204中进入的气体，将由于出风罩22与中盖20的凹陷660的密封结构而直接从出风罩22排出，以免气体泄露，保证吸附效果。
例如，限位柱656和限位孔657之间存在配合间隙，可以使得气体可以通过该间隙流入到清洁架642靠近底部600的一侧，进而再通过吸附孔659进入到风腔658内，从而改变风腔658的气压。例如，当清洁装置1移动到清洁区域以外的区域时，例如清洁装置1部分与待清洁面分离时，限位柱656和限位孔657之间间隙可以作为一个泄气孔，改变风 腔658的气压，使得清洁装置1进行相应的控制操作。
例如，清洁装置1中也可以在其他位置直接设置至少一个泄气检测孔，例如可以设置在第二模组的边缘处，以更易于检测到清洁装置1的行进状态，从而更加及时和灵敏为清洁装置1起到提示作用。
参考图2和图5A，风腔658包括对应于第一模组630的第一子风腔661、对应于第二模组640的第二子风腔662、第一电子控制阀663以及第二电子控制阀664，其中，第一电子控制阀663被配置为控制第一子风腔661的启闭，调整第一子风腔661的开口面积；第二电子控制阀664被配置为控制第二子风腔662的启闭，调整第二子风腔662的开口面积。
参考与1和图5A，下壳组件10包括负压机构05，负压机构05包括至少一个风腔658、进风罩203、至少一个风机21以及出风罩22，其中，出风罩22包括至少两个出风通道，即出风通道666和出风通道667。
参考图1A，清洁装置1中的上壳30包括出风口372和出风口374，出风罩22包括导流端262和导流端264，且导流端262和导流端264位于中盖20的轮廓部26的靠近上壳30的表面267的上方，并且导流端262与出风口372连通、导流端264与出风口374连通，从而将气流经过出风罩22从上壳30的出风口372和出风口374排出。
图5B为本公开的一实施例提供的一种清洁装置中气流的流通路线的示意图。
参考图1A和图5B，气流在清洁装置1中的主流经路线可以包括：风机21运转，气流从清洁装置1的底部从进风罩203的进风口204进入风机21；风机21包括多个气流孔215，进入进风罩203中的气流沿远离清洁装置1的下壳组件10的方向经过风机21流通至出风罩22；最后，气流可从出风罩22上的导流端262和导流端264流出，并由出风口372和出风口374排出清洁装置1。
参考图2和图5A，第一电子控制阀663设置于第一子风腔661的进气通道处，第二电子控制阀664设置于第二子风腔662的进气通道处。例如，第一电子控制阀663可以与第二电子控制阀664分别调控，即二者可选择性地开启和关闭，控制不同步。通过设置第一电子控制阀663与第二电子控制阀664，还可以调整对应于第一模组630的第一子风腔661的开口大小和对应于第二模组640的第二子风腔662的开口大小，进而调整进风量，以使第一模组630和第二模组640与待清洁表面之间的压力呈现不同，便于更好地控制清洁装置1的运动。
例如，在一些实施例中，负压机构05也可以是双风机，单风腔和双出风通道或双风机、双风腔和双出风通道等多种组合模式，本公开对于风腔658、进风罩203、风机21以及出风罩22的数量和设计形式不作限制。
该清洁装置1可以适用于多种情况下的表面清洁。例如，用在水平面上的清洁，负压机构05可以增大清洁装置1与水平面之间的压力，增加摩擦力，提高清洁效果。用于非水平面的清洁，负压机构05可以使清洁装置1吸附在非水平面上。
在一些示例中，清洁装置1是擦窗机器人，待清扫面包括窗户或墙面。例如，窗户可以是有框窗户或者无框窗户。例如，有框窗户可以是家用的窗户，无框窗户可以是大型落 地窗等。
图6为本公开的一实施例提供的辅控制板与中盖连接处的局部剖面图。
参考图1A、图5A和图6，在风腔658内设置有压力传感器668，传感器668被配置为检测风腔658内的气压。如图6所示，清洁装置1还包括检测腔550，且检测腔550与风腔658连通。检测腔550和风腔658构成密封腔。检测腔550位于辅控制板522和中盖20之间，中盖20设有至少一个检测孔560，检测腔550与风腔500通过检测孔560连通。其中，检测孔560可以起到平衡风腔500和检测腔550之间的气压的作用。另外，检测孔560还可以降低风腔内的水汽接触到气压传感器540，避免气压传感器540的工作不稳定，保证气压检测的准确度。
图7为图1D中的清洁装置中第二模组的局部结构示意图。
参考图1A、图2和图7，在行走部件296的行走方向的前后均设置刮水条，即刮水条670和刮水条671。例如，当清洁装置1中的第二模组640随着行走部件296移动时，通过设置刮水条670和刮水条671，可以刮去行走部件296在行进方向上的污渍，例如水等，避免水过多时行走部件296发生打滑，进而影响清洁装置1的吸附效果。例如，当清洁装置1为擦窗机时，刮水条670和刮水条671可以避免擦窗机打滑发生的跌落。
例如，刮水条670或刮水条671的数量和形式可以根据实际产品设计的需求而定，本公开对此不作限制。
参考图2和图7，行走部件296包括至少一个滚轮673，在滚轮673的至少一侧设置有清洁部672以清理滚轮上的污物。例如，行走部件296中也可以设置一个或多个滚轮，以满足不同的产品设计需求。通过设置清洁部672，可以对行走部件296实现清洁，并保证行走部件296在行进方向上无卡滞、正常平稳的移动。
例如，清洁部672可以设置为2个，并且清洁部672可以设置于行走部件296沿行进方向上相对的两端，或者也可以根据实际设计需求而定，本公开对于清洁部672的设置位置不作限制。
例如，在本公开的一些实施例中，清洁部672可以是清洁毛刷；或者，清洁部672也可以是任何其他的能够实现对行走部件296实现清洁的部件，本公开对此不作限制。
例如，在本公开的一些实施例中，行走部件296可以是履带轮组，清洁部672也可以配置为清洁履带和履带轮上的杂质。例如，行走部件296为履带轮组时，履带轮组的数量可以不限于一个，即可以根据设计需求增加为多个，以增加清洁装置的清洁面积和清洁力度。
参考图2和图7，清洁架642中设有至少一个子吸附区675，其中，每个子吸附区675中包括至少一个子吸附孔676，至少一个子吸附孔676间隔设置，并且每个子吸附孔676的截面小于第二开口607的开口截面。如图7所示，子吸附区675的数量为两个，且两个子吸附区675设置在第二开口607的两侧。
参考图1A、图2、图5A及图7，在负压机构05的作用下，气流可以从第二开口607进入清洁架642靠近风机21的一侧，进而通过第二安装部641的吸附孔659进入到风腔 658中。同时，气流也可以从子吸附区675通过子吸附孔676进入清洁架642靠近风机21的一侧，进而进入到风腔658中。例如，第二开口607的开口区域可以作为清洁装置1的主吸附区。采用主吸附区和子吸附区结合的设计方式可以增大清洁装置1中负压腔的面积，提高吸附效果。例如，当子吸附孔676设置为一个时，便于加工制造，可以减小成本；当子吸附孔676为多个时，可以保证扩大清洁架642的进风量，进而在吸附过程中保证清洁架的强度，减少损坏和变形，本公开对于子吸附孔676的数量不作限制。
例如，在本公开的一些实施例中，清洁装置1中的第一模组630和第二模组640的数量和位置关系可以包括多种。
图8A为本公开的一实施例提供的一种清洁装置中一种第一模组与第二模组的相对位置示意图。图8B为本公开的一实施例提供的一种清洁装置中另一种第一模组与第二模组的相对位置示意图。图8C为本公开的一实施例提供的一种清洁装置中再一种第一模组与第二模组的相对位置示意图。
参考图2和图8A，第一模组630与第二模组640并排设置，且第一模组630的旋转轴线678在第二模组640的第一对称平面679内，其中，第一对称平面679为在垂直于第二模组640的直线行走方向上经过第二模组640的中心的平面。第二模组640相对于第一对称平面679结构对称。
图2中的第一模组630与第二模组640的相对位置关系与图8A相同。
如图8A所示，第一模组6308与第二模组6408并排设置，第一模组6308可以按照方向Y或方向Y的反方向转动，第二模组6408可以按照方向X或方向X的反方向直线行进。
例如，第一模组6308在驱动元件的作用下，(例如，驱动元件可以与图1A所示的驱动电机14相同)按照方向Y方向转动时，第一模组6308对应的作用力为F4；反之，第一模组6308对应的作用力为F3。例如，第二模组6408按照方向X行进时，则应对其施加的驱动力为F1，反之，则应对其施加的驱动力为F2。
例如，可以使得第一模组6308与第二模组6408之一作为驱动轮组。当第一模组6308作为驱动轮组时，当第一模组6308受到的驱动力可以保持一定，通过调节第二模组6408所受到的驱动力F1或驱动力F2的大小，使得第二模组6408与第一模组6308配合协调，实现清洁装置的前进、后退及转弯等运动。同理，也可以使得第二模组6408作为驱动轮组，使得第二模组6408受到的驱动力一定，通过调节对第一模组6308的驱动力大小来控制清洁装置的运动状态。
例如，参考图2，在本公开的一些实施例中，下壳组件10可以包括多个第一模组630以及多个第二模组640，且多个第一模组630间隔设置，多个第二模组640并列间隔设置，并且每个第一模组的旋转中心线与每个第二模组的直线运动方向无交叠。
如图8B所示，清洁装置可以包括一个第一模组6318和一个第二模组6418，二者并列间隔设置，并且第一模组6318的旋转中心线L2与第二模组6418的直线运动方向L1无交叠，以保证第一模组6318可以和第二模组6418配合行进。
进一步地，清洁装置中的第一模组和第二模组也可以为多个。如图8C所示，下壳组件可以包括第一模组6328、第一模组6338、第二模组6428、第二模组6438以及第二模组6448，第一模组6328和第一模组6338并列间隔设置，第二模组6428、第二模组6438以及第二模组6448并列间隔设置，并且每个第一模组的旋转中心线与每个第二模组的直线运动方向无交叠。例如，第一模组6328、第一模组6338也可以为非并列的设置形式。
通过改变至少一个第一模组以及至少一个第二模组的数量以及相对位置，可以使得实际产品的设计形式更加多样化，进一步提升了清洁装置的整体性能。
本公开还提供一种清洁装置，包括上述任一所述下壳组件。
例如，本公开的实施例提供的清洁装置还包括至少一个踏空开关、至少一个泄气检测孔686、单向部、第一清洁件和第二清洁件。
如图1A所示，清洁装置1包括两个踏空开关，即踏空开关680和踏空开关681，踏空开关680设置于清洁装置1的第一端部683，踏空开关681设置于清洁装置1的第二端部682。例如，踏空开关680或踏空开关681还可以设置在清洁装置1的第三端部684。由图1A可知，清洁装置1的第一端部682、第二端部683和第三端部684可以是清洁装置1中的下壳本体100上的任何边缘或角落的位置，以易于检测到清洁装置1的行进状态。清洁装置1中的各个踏空开关被配置为检测清洁装置1的移动位置信息，并将移动位置信息反馈至清洁装置，进而控制清洁装置1的行进状态，以防止清洁装置1移动至待清洁区域之外。
参考图1A和图2，至少一个泄气检测孔686设置于第二模组640的靠近第二端部682的第二区域内687或靠近第一端部683的第一区域(未示出)内，被配置为改变并反馈清洁装置1内的气压。第一区域与第二区域687相对于第一对称平面679对称。例如，第二区域687可以是靠近踏空开关681的区域，易于在清洁装置1行进至待清洁面之外时及时地通过泄气检测孔686改变风腔658的气压，以起到提示的作用。泄气检测孔686与各个踏空开关均能起到踏空检测的功能，可以为清洁装置1提供防止跌落的双重保护。关于泄气检测孔686的作用原理可参见前述关于限位柱656和限位孔658的配合处作为泄气孔的相关描述，在此不再赘述。
图9A为本公开的一实施例提供的一种清洁装置中喷嘴出水范围与出风口的出风范围的示意图。图9B本公开一实施例提供的一种出风口的示意图。
参考图9A、图9B，出风口910包括单向部911，单向部911沿出风方向M是单向导通的，也即，当气流沿着出风方向M从出风口910流出时，单向部911开启，当气流逆着出风方向M流通至出风口910时，单向部911关闭，因此气流逆着出风方向M无法从出风口910流入。通过设置单向部911，可以实现气流只能沿着出风方向M从出风口910流出。同时，还可以通过单向部911调整清洁装置内部的气体压力。
例如，单向部911可以是单向阀或单向瓣膜，当然，单向部911的形式包括但不限于此，单向部911也可为其他形式的结构。
参考图1A、图9A和图9B，喷嘴31的出水区域为A1，出风口372的出风范围为A2， 由于出风口910内部设置有单向部911，可以使得清洁装置1内部的气流不受出风口910附近的外界气流的干扰，从而有序的按照一个方向进出流动，并且出水区域为A1与出风范围为A2无交叠。同理，出风口374的出风范围(未示出)也与出水区域为A1无交叠。因此，当清洁装置1运转时，可以避免喷嘴31喷出的水从进风口204进入清洁装置1。
例如，第一清洁件(未示出)可以粘接或卡接在第一模组630远离下壳本体的一侧，第二清洁件(未示出)粘接或卡接在第二模组640远离待下壳本体的一侧。例如，第一清洁件可以通过一个环形件与第一模组630上对应设置的卡扣进行连接；第二清洁件可以通过一个环形件与第二模组640上对应设置的卡扣进行连接。例如，第一清洁件与第一模组630的固定方式可以和第二清洁件与第二模组640的固定方式相同或不同，本公开对此不作限制。
例如，第一清洁件和第二清洁件可以包括清洁抹布或清洁毛刷，以及其他可以起到清洁效果的元件，本公开对于第一清洁件和第二清洁件的材料不作限制。
例如，如图5A所示，在清洁装置1中，进风罩203处设置有整流结构691，以对进入到气腔658内的气流进行导向，使得气流能够更加顺畅地进入至风机21。
例如，参考图1A和图5B，在清洁装置1中，风机21连接在中盖20上，风机21与中盖20之间设置有减震件，风机21与出风罩22之间也设置有减震件，以在清洁装置1的操作过程中起到减震作用，从而保护器件。例如，减震件可以是硅胶圈，或者其他任何起到减震缓冲的元件，本公开对此不作限制。
参考图1A、图1B和图1C，电池组15设置在上壳30和下壳组件10之间，通过上壳10上的筋位6152和下壳组件10上的筋位6150固定电池组15的位置，不需要使用任何其他的固定元件，可以减少清洁装置1的零部件数量。例如，在本公开的一些实施例中，电池组15也可以外置于清洁装置1，通过电线与电路板等电子连接，减轻清洁装置1的重量。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，本公开的保护范围应以所述权利要求的保护范围为准。
