电机组件
参考图21-24，图21为一实施例中电机组件的一个角度的结构示意图。图22为一实施例中电机组件的另一个角度的结构示意图。图23为一实施例中电机组件的截面图。图24为一实施例中电机组件的结构分解图。电机组件6包括电机壳体61和设置于电机壳体61内的干湿电机(图中未示出)。电机壳体包括上壳体62和下壳体63，上壳体62由周壁和顶壁构成，下壳体63由周壁和底壁构成，周壁、顶壁和底壁之间限定有安装空间。干湿电机安装于安装空间内，用于产生冷却气流和抽吸气流。周壁和/或顶壁上开设有冷却风入口，在本实施例中，顶壁上开设有冷却气流进入的冷却风入口621和过线孔622(参见图21)，顶壁的内侧设置有减震垫623，减震垫与干湿电机相接触。
参考图22和23，下壳体的底壁开设有进风通道631和出风通道632，干湿电机的进风口处设置有橡胶垫633，进风口通过橡胶垫与进风通道631流体连接而实现密封。橡胶垫633设置于干湿电机和下壳体63的底壁之间，同时起到减震和密封的作用，橡胶垫633用于分割进风通道631和出风通道632。设置于底壁上的进风通道631呈圆台状，沿气流流动方向，进风通道631的截面积逐渐减小。出风通道632的横截面为长条状，出风通道632设置于进风通道631和周壁之间，出风通道632远离污水箱安装腔的开口，比进风通道631更加靠近污水箱安装腔的内壁。冷却气流从冷却风入口621进入电机内部对干湿电机进行冷却后通过出风通道632排出电机壳体。在一个实施例中，抽吸气流B和冷却气流A在干湿电机的叶轮的上游汇合形成混合气流C。即叶轮的旋转即产生抽吸气流，同时产生冷却气流。在其他实施例中，抽吸气流和冷却气流还可以在叶轮下游或者叶轮内汇合形成混合气流。这样，可以降低电机的成本，同时减小电机的体积。当然，可以理解的是，冷却气流的产生还可以是除进风口的叶轮外，其他的设备产生，此处不再详述。干湿电机的外周还设置有密封圈624， 密封圈624与顶壁相贴合，用于将冷却风道和干湿电机的出风通道632分隔开。
参考图17和18。图18中的箭头方向为冷却气流的流动方向。电机组件6安装到电机组件安装腔223内。电机组件安装腔223位于污水箱安装腔221的上方。污水箱5安装至主体限定的污水箱安装腔221内，主体2还开设有与污水箱安装腔连通的排气孔225，排气孔225用于将冷却气流或混合气流引导至污水箱安装腔221。在设备正常工作时，从出风通道排出的气流从污水箱和主体之间的缝隙排出到外界，可以有效地降低噪音。
继续参考图23，抽吸气流B和冷却气流A在电机组件的叶轮上游汇合形成混合气流C，混合气流C流经叶轮后经出风通道632排出到污水箱安装腔221。污水箱安装腔221的底壁开设有漏水孔(图中未示出)，用于将混合气流中的至少部分液体引导至待清洁表面和/或表面清洁设备的清洁头。
在其他实施例中，主体2还开设有与净水箱安装腔连通的排气孔，排气孔用于将冷却气流或混合气流引导至净水箱安装腔。净水箱安装腔的底壁也可以设置有漏水孔。在一个进一步地的实施例中，抽吸气流和冷却气流在电机组件的叶轮上游汇合形成混合气流，混合气流流经叶轮后经出风通道排出到净水箱安装腔。
继续参考图24，进风通道631和出风通道632的端部均设置有密封件634，密封件634设置于下壳体63的底壁的外侧且设置于电机壳体和电机组件安装腔的底壁之间，用于分割进风通道和出风通道。进一步地，两个密封件可一体成型，即在一个橡胶垫上开设两个相对独立的孔。
继续参考图22，电机壳体的下壳体63的外侧设置有导电触头635，两个导电触头635可伸缩的设置于下壳体的安装支架636上，导电触头635的一部分可深入到污水箱安装腔内，与污水箱上的导电片电连接。导电触头设置于进风通道和出风通道之间的位置。
继续参考图22，电机壳体的下壳体63还设置有检测装置637，检测装置637在过滤海帕安装到位后，可以发出信号，此时机器可以正常使用，如果过滤海帕没有安装到位，则机器发出报警信号，提醒用户安装海帕。检测装置可以为干簧管或其他可以发出信号的装置，过滤海帕上设置有磁铁。检测装置和出风通道分别位于进风通道的两侧。
参考图23或24，电机壳体61和主体之间设置有减震件63，减震件63可以设置在主体上，还可以设置在电机壳体上，或者减震件63是独立于两者的结构，在本实施例中，电机壳体和前框架之间设置有两个弧形减震片，电机壳体和后框架之间的减震片黏贴到电机壳体上。上壳体和下壳体之间的结合处设置有密封圈。
枢转结构
参考图25-31，图25为一实施例中枢转结构安装到枢转支架的结构示意图。图26为一实施例中枢转结构的结构示意图。图27为一实施例中枢转结构的分解图。图28为一实施例中枢转结构的上连接件和下连接件分离的结构示意图。图29为一实施例中枢转结构的剖面图(第二限位结构位于锁定位置)。图30为一实施例中枢转结构的剖面图(第二限位结构位于解锁位置)。图31为一实施例中枢转结构的结构示意图。主体2和清洁头3之间通过枢转结构7枢转连接。枢转结构7包括上连接件71和下连接件72，上连接件71的一端连接到前框架的底端，上连接件71的另一端与下连接件72的一端旋转连接，可以确保主体相对于清洁头绕主体的轴线转动，下连接件72的另一端与清洁头枢转连接，确保主体相对于清洁头前后转动。具体地，参考图26或者图28，下连接件72绕第一轴线Y可枢转的连接到清洁头以使主体相对于清洁头沿行进方向枢转，上连接件71和下连接件72之间可绕第二轴线X相对旋转以使主体相对于清洁头偏转，第一轴线Y和第二轴线X基本垂直。参考图29，第二轴线X与主体长度 方向的轴线Z之间的角度为30°-50°之间的任意值。采用这种枢转结构，当主体绕第二轴线X旋转式，把手部分会发生较大的偏转，偏离第二轴线X，此时，对把手稍微施加一点力，清洁头即可被主体施加的力改变运动方向，清洁头的下方设置有至少一个万向轮，该枢转结构与万向轮配合，可以使用户更加方便的操控清洁设备，实现滚刷的转向，同时，清洁头的下方安装有万向轮，在手柄的带动下，清洁头还能横向运动，适应不同的场景。
继续参考图29，上连接件71大致呈弧形管状结构，其内为中空，塑料管73贯穿中空结构，组成抽吸管路的一部分，以使污水箱与清洁头上的吸嘴流体连通，塑料管73的一端设置有橡胶管，部分橡胶管深入污水箱安装腔内，当污水箱安装到污水箱安装腔后，污水箱的进气管与橡胶管密封接触。塑料管73处设置有脏污检测装置77，具体地，塑料管73的径向两端分别设置有红外发射装置和红外接收装置，红外发射装置发射的光穿过塑料管后被红外接收装置接收，当抽吸管道中的脏污比较多时，大部分光被阻挡，不能被接收，因此，脏污检测装置77会发出信号，控制器接收到信号后控制干湿电机提高转速。当脏污检测装置77检测到脏污比较少时，控制干湿电机降低转速。
继续参考图26和图27，下连接件72整体呈L型，包括直立段721和水平段722，直立段721限定有通孔，软管74贯穿通孔，软管74的两端分别设置有橡胶管，分别与对应的管道密封连接，软管的一端与塑料管73流体连接，另一端与清洁头的吸嘴流体连通，水平段722远离直立段721的一端设置有转轴723，下连接件72通过转轴723可绕清洁头上的枢转支架78枢转，以使主体相对于清洁头前后枢转。转轴723上设置有第一限位结构724，在本实施例中，第一限位结构724为第一凸起结构，第一凸起结构与设置于清洁头上的第二凸起结构配合，当主体处于直立位置时，两个凸起结构相配合以限定主体相对于清洁头的前后转动(在没有外力的作用下)。参考图29和图30，下连接件上还设置有 第二限位结构75，第二限位结构75可与上连接件配合，限定上连接件和下连接件之间的相对运动，第二限位结构75具有锁定位置和解锁位置，在解锁位置，上连接件71和下连接件72之间可相对旋转，在锁定位置，上连接件71和下连接72之间不可相对旋转。具体地，在本实施例中，第二限位结构75是一个可伸缩的滑块，当主体相对清洁头倾斜时，滑块向外伸出，与上连接分离，此时，上连接件71和下连接件72可相对转动，当主体相对于清洁头直立时，滑块收缩，部分滑块深入到上连接件限定的凹槽内，此时，由于滑块与下连接件相连，所以上连接件和下连接件之间无法发生相对转动。
参考图28，直立段721的外表面设置有滑槽727，上连接件71和下连接件72之间通过滑槽727引导两者之间的相对转动，上连接件72的周壁上开设有通孔711，定位片76可以穿过通孔深入到滑槽内，限定上连接件71和下连接件72沿轴向方向的运动。定位片76为台阶状，定位片76的一部分结构与滑槽727配合，使定位片76与下连接件72之间沿轴向方向相对静止，定位片76的另一部分结构与通孔711配合，使定位片76与上连接件71之间沿轴向方向相对静止，这样可以确保上连接件和下连接件之间沿轴向方向相对静止，而只能绕轴相对转动。
参考图31，下连接件72的转轴723处设置有开关结构726，该开关结构726与设置于清洁头的微动开关相配合，实现直立断电的功能，即当主体位于直立状态且未放置到基座时，表面清洁设备处于断电状态，电池不对任何元器件进行供电。上连接件71和下连接件72限定的通孔除了容纳抽吸管道外，还供至少部分线缆穿过，其内限定有单独的过线孔，具体结构就不再详述。
清洁头
参考图32-图35，图32为一实施例中清洁头的结构示意图。图33为一实施例中清洁头拿掉上壳体后的结构示意图。图34为一实施例中清洁头上壳体的结构示意图。图35为一实施例中清洁头拿掉上壳体和滚刷盖之后的结构示意图； 清洁头3上设置有用于对接枢转结构7的枢转支架78(如图35所示)，下连接件72可枢转设置于枢转支架上。清洁头3还包括上壳体31和下壳体32，上壳体31和下壳体32之间下定有安装空间，用于安装各种零部件。上壳体31和下壳体32均呈工字型，沿运动方向两端分别限定有容纳滚刷的空间，分别用于安装前滚刷33和后滚刷34。滚刷的上方设置有滚刷盖38，与上壳体31、下壳体32共同限定滚刷腔。滚刷盖的内侧设置有刮水条和/或梳齿，以刮除滚刷上的脏污和/或毛发。
继续参考图34，上壳体31设置有锁扣311，通过锁扣311可以释放滚刷盖38，上壳体31还设置有弹出机构312，弹出机构312在滚刷盖解锁后将滚刷盖弹出一定的距离，方便用户取下。上壳体31和枢转支架78共同限定下连接件的前后、上下方向的运动，只允许下连接件绕转轴做枢转运动。
继续参考图35，下壳体32安装有水泵321、线路板322、滚刷驱动组件8、臭氧发生器323等结构。下壳体32还设置有万向轮和/或滚轮。水泵321和滚刷驱动组件8分别设置于抽吸管道324的相对两侧，臭氧发生器323设置在抽吸管道324的后方，线路板322设置于水泵321的后方。水泵321通过水泵盖安装于下壳体内，水泵321的外周设置有减震垫。滚刷驱动组件8通过组建盖安装于下壳体，驱动电机的外周设置有减震垫。
下壳体32的沿滚刷轴向方向的两端分别设置有漏水孔(图中未示出)，用于将清洁头内部的液体导向待清洁表面。
参考图36-38，图36为一实施例中清洁头另一角度的结构示意图。图37为一实施例中清洁头的剖面示意图。图38为一实施例中清洁头中的分配器裸露在外的结构示意图。继续参考图38，清洁头上设置有分配器35，用于将清洁液体喷洒到前滚刷上，分配器35安装到下壳体限定的凹槽内。分配器35为长条状结构，设置有导水槽，导水槽内均匀设置有喷孔，将清洁液喷洒至滚刷，滚刷 刮条36设置在分配器下方，作用是在润湿滚刷前将滚刷上的大部分脏污刮除掉。滚刷刮条36可以为金属材料制成或者是为硬塑料制成。
继续参考图36和37，下壳体上还设置有地面刮条37，用于对待清洁表面进行刮擦。地面刮条37设置在前滚刷后方，在前进过程中将遗漏的脏污保持在抽吸口处，尽可能的减少脏污遗漏。地面刮条37通过安装支架39安装到下壳体，安装支架39上还设置有至少一个滚轮，安装支架39可拆卸地设置于下壳体，用户通过拆卸安装支架，可对刮条和滚轮进行清理。安装支架39上还设置有通孔391，通孔391与抽吸管道连通，通孔处设置有密封盖392，可将通孔密封，当密封盖392打开后，用于可通过通孔清理堆积到抽吸管道324内的脏污。地面刮条可以为软胶或者硬胶材料制成，此处不做限制。
继续参考图37，前滚刷33和后滚刷34反向转动，前滚刷33所在的滚刷腔内设置有刮除滚刷脏污的滚刷刮条36，抽吸管道324连通前滚刷腔，将刮除的脏污抽吸到污水箱内，后滚刷34所在的滚刷腔不与抽吸管道连通，是一个单独的腔室，后滚刷腔处同样设置有后刮条325，后刮条325的作用是将后滚刷上的至少部分脏污刮除，防止脏污进入滚刷腔内，后刮条325设置于后滚刷的前方且安装到下壳体上，后刮条325在高度方向上的位置比待清洁表面略高一些，不与待清洁表面接触。后刮条设置于后滚刷前方，再向前清扫时，可以将后滚刷上的脏污不断的刮下来后依靠后滚刷将脏污向前推，而不至于被遗漏在待清洁表面，当设备向后时，被刮掉的脏污留在待清洁表面，随即被前滚刷扫起或吸嘴吸起后回收到污水箱。
参见图39-41，图39为一实施例中一个角度下清洁头的剖面示意图。图40为图39所示A区域的结构放大图。图41为一实施例中另一角度下清洁头的剖面示意图。在本实施例中，清洁头3包括吸嘴329和抽吸管道324，吸嘴329临近或接触待清洁表面。吸嘴内可以设置有滚刷等搅拌件，还可以不包括任何搅拌件。抽吸管道324与吸嘴329流体连通，以通过吸嘴329对待清洁表面的脏 污进行回收。抽吸管道324内限定有储藏空间328，储藏空间328配置成储存至少部分抽吸管道内残留的脏污。这里所指的残留的脏污，是指设备停止后，部分附着到管道内的脏污因重力的作用，而向吸嘴处回流。如果脏污较多，那么可能会从吸嘴重新流到待清洁表面。而储藏空间328的作用即将这部分脏污暂时储存起来，以在设备下次运行(自清洁或者正常工作)时，重新被回收到污水箱。在抽吸管道内设置储藏空间，可以有效收集设备停止后回流的脏污，防止附着到抽吸管道的脏污因重力作用回流到待清洁表面，给待清洁表面造成二次污染。储藏空间由清洁头的下壳体限定而成。在一个实施例中，水平段和下壳体一体模制而成，储藏空间为部分水平段向下凹陷形成。
继续参考图39-41，清洁头3的底壁设置有与储藏空间328相连通的通孔，通孔处设置有密封盖392，以密封储藏空间与外界。该密封盖392打开后，用户可以对储藏空间328和抽吸管道324进行清理，这样可以保持管道内的清洁，避免抽吸管道324的内壁附着较多的脏污，产生异味。
当然，在其他实施例中，水平段326和储藏空间328还可以是分开的。当储藏空间328由一个单独的零件限定而成时，该零件可以被单独取出，以进行清理。当限定储藏空间的零件被取出后，用户可以通过该位置对抽吸管道进行清理。
在一个实施例中，沿气流流动方向抽吸管道包括依次排布水平段326和倾斜段327。这里的水平段326并不是特征该段管道是完全水平设置，可以有一定的倾斜角度，但角度不宜过大。倾斜段327是指该段管道相对于水平段倾斜向上，通过倾斜段，脏污进入到污水箱或者进入与污水箱连通的管道内。由于倾斜段倾斜设置，沿垂直方向倾斜段具有底端和顶端，为了使整个倾斜段残留的脏污被收集，储藏空间设置于倾斜段的底端。进一步地，储藏空间设置于水平段和倾斜段的交汇处。沿气流流动方向，水平段的底壁逐渐向下倾斜，即从吸 嘴到储藏空间这段距离，沿气流流动方向水平段逐渐向下倾斜，这样，水平段,36残留的脏污也可以被有效的收集到储藏空间328内。
滚刷驱动组件
参考图42-图43，图42为一实施例中驱动组件的结构示意图。图43为图42所示驱动组件的剖面示意图。滚刷驱动组件8包括驱动电机81、减速机构82和传动机构83，减速机构82包括与电机的输出轴传动连接的行星轮系，行星轮系包括与传动轴传动连接的太阳轮、相对于太阳轮固定的齿圈和设置于太阳轮和齿圈之间的至少一个行星轮，与行星轮传动连接的主动轮，与主动轮传动连接的从动轮，主动轮和从动轮可采用同一型号，主动轮和从动轮均通过各自的传动机构将动力输出至对应的滚刷，减速机构设置于由前壳体和后壳体限定的安装空间内。
传动机构83包括与主动轮或从动轮传动连接的输出齿轮，与滚刷传动连接的传动齿轮，用于传动连接输出齿轮和传动齿轮的皮带，传动齿轮通过花瓣状的传动件与滚刷的一端传动连接，
传动机构83还包括传动支架831，传动支架831包括与后壳体对接的对接部832和限定有传动空间的安装部833，对接部832和安装部833可一体模制而成，对接部和/或安装部的外周可设置有减震垫，通过减震垫与清洁头的上壳体和/或下壳体接触，起到减震作用。
尽管本发明的实施方案已公开如上，但其并不仅限于说明书和实施方式中所列运用，它完全可以被适用于各种适合本发明的领域，对于熟悉本领域的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本发明并不限于特定的细节和这里示出与描述的图例。
