以下将参照附图更详细地描述本公开。在各个附图中，相同的元件采用类似的附图标记来表示。为了清楚起见，附图中的各个部分没有按比例绘制。
下面结合附图和实施例对本公开进行详细说明。
实施例一
本实施例提供了一种刷头，图1和图7是本公开的实施例提供的手持清洗设备的示意图，请查看图1和图7，该手持清洗设备包括：表面行走部160和直立部150，表面行走部160与待清洁表面接触，表面行走部160与直立部150连接，表面行走部160工作时，直立部150用于使表面行走部160移动，直立部150内部还形成有容纳空腔，能够容纳电气设备等；手持清洗设备还包括供电电池，用于给手持清洗设备供电。手持清洗设备的清洁对象包括瓷砖，地板，水泥地，玻璃表面，等具有平整表面可以用水清洗的表面对象。
在使用手持清洗设备时，直立部150相对于表面行走部160倾斜，这样利用直立部150的重力所产生的下压力，使表面行走部160与待清洁表面更加贴合，并且方便用户利用直立部150推动表面行走部160，更加省力。而当手持清洗设备放置在充电桩上时，直立部150相对于表面行走部160垂直，从而使减小手持清洗设备的占用空间。
表面行走部160的底部还设有滚轮120，优选地，滚轮120位于表面行走部160的行进方向的后端；可选地，滚轮120位于表面行走部160的前后两侧，以减小表面行走部160底部与待清洁面的摩擦阻力，从而减小用户的推拉力，提高用户的使用体验。
表面行走部160中还包括至少两个不同轴的滚刷，滚刷是旋转轴为水平的刷子，用于清洁待清洁表面的污渍。
本实施例包括前滚刷10和后滚刷20，前滚刷10和后滚刷20并列设置并且设置于同一水平面；前滚刷10与后滚刷20朝向不同的方向做周向旋转，最终将待清洁表面的垃圾收纳至前滚刷10和后滚刷20之间。滚刷的转速低于一定数值，优选地低于3000转/分钟(r/min)。如果滚刷的转速过快，例如大于3000r/min，很有可能将滚刷从待清洁表面卷起的污液发生雾化的现象，进而可能会使手持清洗设备变得脏污，从而影响清洁的效果。
由于在表面行走部上前后排列地设置至少两组滚刷，在实际使用本公开的手持清洗设备的过程中，用户进行一次推送或拉回的动作，能够对地面进行两次的擦拭，相对于刷头仅仅设置有一组滚刷的现有手持清洗设备，大大提高了清洁效率。另外，由于设置了至少两组滚刷，也即需要至少两组对应的齿轮箱和驱动电机，这样使得整个表面行走部的重量比现有的单组滚刷的手持清洗设备更大，保证了该手持清洗设备在使用过程中能够对待清洁表面产生更大的对地压力，有效地改善了该手持清洗设备对顽固污渍的清洁能力。
本公开的手持清洗设备是用于清理待清洁表面的污渍，图1所示为滚刷安装在手持清洗设备的表面行走部160上的主视图。其中，在使用该手持清洗设备进行清理污渍时，前滚刷10与后滚刷20朝向不同的方向做周向旋转时，在手持清洗设备的放置方向与图1相同时，也就是说前滚刷10位于后滚刷20的左侧时，前滚刷10逆时针旋转，后滚刷20顺时针旋转，而在手持设备的放置方向与图1相反时，也就是说前滚刷10位于后滚刷20的右侧时，前滚刷10顺时针旋转，后滚刷20逆时针旋转；或者前滚刷10与待清洁表面的接触点朝向后滚刷20的方向周向旋转，后滚刷20与待清洁表面的接触点朝向前滚刷10 的方向周向旋转，最终使得待清洁表面的污渍收纳至前滚刷10和后滚刷20之间，再由位于前滚刷10与后滚刷20之间间隙上方的抽吸管路30的入口进入回收箱90内，实现了污渍的清扫与回收。
如图5、图6和图10所示，本公开实施例包括至少两个不同轴的滚刷，而其中一个滚刷中的前滚刷10或后滚刷20包括同轴设置的第一滚刷单体201和第二滚刷单体202，在本实施例中，以后滚刷20包括两个滚刷单体为例进行说明。如图5和图6所示，第一滚刷单体201和第二滚刷单体202之间设有皮带110，皮带110的两端分别朝向第一滚刷单体201和第二滚刷单体202的方向均延伸有转动杆190，第一滚刷单体201和第二滚刷单体202分别套设在转动杆190上；第一电机与皮带110(参见图2)连接，通过驱动皮带110转动，从而带动第一滚刷单体201和第二滚刷单体202转动。后滚刷20被分为同轴设置的第一滚刷单体201和第二滚刷单体202，第一滚刷单体201和第二滚刷单体202相互靠近的位置设置有皮带110，皮带110两端的转动杆190用于连接第一滚刷单体201和第二滚刷单体202，第一电机驱动皮带110，皮带110带动转动杆190转动，从而使得第一滚刷单体201和第二滚刷单体202转动。在后期更换维修时，方便拆卸，且无需更换整个滚刷，节约成本。
进一步地，如图2和图5所示，在第一滚刷单体201和第二滚刷单体202之间的缝隙处设有导流板170，导流板170的下部逐渐向远离第一滚刷单体201及第二滚刷单体202的方向倾斜，示例性的，后滚刷20包括第一滚刷单体201和第二滚刷单体202，前滚刷10包括一个完整的滚刷单体，第一滚刷单体201和第二滚刷单体202之间的缝隙设置导流板170，导流板170的下部逐渐向远离第一滚刷单体201和第二滚刷单体202的方向倾斜，也就是向靠近前滚刷10的方向倾斜。
在具体应用中，当两个滚刷通过旋转清理污渍时，导流板170能够阻挡污渍进入第一滚刷单体201与第二滚刷单体202之间的缝隙内，从而避免污渍在缝隙内堆积而阻碍转动杆190与皮带110轮之间的传动动作，并且位于导流板170上的污渍可通过抽吸管路30的抽吸力沿着导流板170到达抽离管路的入口，并经由入口及抽吸管路30进入回收箱90内，从而也避免了污渍存留在导流板170上，提高了污渍的回收效果。第一滚刷单体201和第二滚刷单体202同时朝向同一个方向转动。
如图6和图10所示，通过将其中一组滚刷设置为同轴设置的两个滚刷单体，分别为第一滚刷单体201及第二滚刷单体202，并且第一滚刷单体201和第二滚刷单体202分别套设在转动杆190，设置在两个滚刷之间的转动杆190通过皮带110由第一电机驱动，采用这种结构设置，使得第一滚刷单体201和第二滚刷单体202可以从表面行走部160的两侧安装到转动杆190上，这样可以保证在第一滚刷单体201和第二滚刷单体202安装到位后，两个滚刷的外侧边缘能够与表面行走部160的侧壁的边缘140齐平，这样在手持清洗设备使用过程中，能够对墙角、墙沿、家具和墙面的接缝处等便利地进行清洁，而不至于出现为了清洁墙角、墙沿、家具和墙面的接缝等比较狭窄的空间而需要反复调整手持清洗 设备的运行方向，有利于提升清洁效率和使用体验。
另外，第一滚刷单体201和第二滚刷单体202是采用从两侧套设在转动杆190的进行安装和拆卸的方式，而现有的滚刷通常是在其一端与表面行走部160通过相互配合的卡合机构来进行安装和拆卸，这种方式一般都需要设置可拆卸的顶盖。在安装滚刷时先要将顶盖打开，然后安装滚刷，最后将顶盖盖上，这种方式步骤繁琐，影响使用体验。而本公开的实施例的第一滚刷单体201和第二滚刷单体202是采用从两侧套设在转动杆190的进行安装和拆卸的方式，比如，可以先将第一滚刷单体201套在转动杆190上，然后相对于转动杆190转动第一滚刷单体201，借助于第一滚刷单体201的内侧边缘与转动杆190上的配合机构，从而将第一滚刷单体201固定住。第二滚刷单体202也可采用此种安装结构。由此可知，此种结构布局极大地改善了滚刷的安装和拆卸便利性，便于用于后续对手持清洗设备的维护。壳体70的侧壁对应于至少一个滚刷的端部开设有避让口701，滚刷的端部延伸至侧壁的避让口701处，且与侧壁的边缘140齐平。
示例性的，如图5所示，后滚刷20包括第一滚刷单体201和第二滚刷单体202，第一滚刷单体201和第二滚刷单体202的轴线位于同一条轴线上，此时第一滚刷单体201远离第二滚刷单体202的一端边缘延伸至壳体70上侧壁的处，并与侧壁边缘140齐平；第二滚刷单体202远离第一滚刷单体201的一端边缘延伸至壳体70上侧壁的避让口701处，并与侧壁140边缘齐平。
滚刷的端部延伸至避让口701处且与侧壁140的边缘齐平，这样在手持清洗设备使用过程中，能够对墙角、墙沿、家具和墙面的接缝处等便利地进行清洁，而不至于出现为了清洁墙角、墙沿、家具和墙面的接缝等比较狭窄的空间而需要反复调整手持清洗设备的运行方向，有利于提升清洁效率和使用体验。在本实施例中，手持清洗设备还包括污渍回收器，污渍回收器用于将待清洁表面或者滚刷上的污浊液体借助于风机的吸力通过污浊液体污水管道流入污渍回收器，实现了污浊液体回收的功能，即，将待清洁表面进行清洁工作之后所产生的污浊液体进行回收。污渍回收器具体可以为采用风机驱动吸嘴抽吸污浊液体的方式实现污浊液体的回收。
污渍回收器包括回收箱90和至少一个抽吸管路30，用于回收收纳至前滚刷10和后滚刷20之间的污渍或位于待清洁表面的污渍。图2是本公开的实施例提供的手持清洗设备的结构剖面示意图，请查看图2和图7，其中，抽吸管路30远离待清洁表面设置，抽吸管路30具有入口和出口，抽吸管路30的入口设置于前滚刷10和后滚刷20之间的间隙的上方，与被收纳至前滚刷10和后滚刷20之间的污渍相对设置；抽吸管路30的出口连接有回收箱90，回收箱90还与风机流体流通，风机能够提供负压，用于将污渍从抽吸管路30的入口抽吸至回收箱90中，从而起到回收污渍的作用。
如图2和图7所示，污渍回收器包括回收箱90和至少一个抽吸管路30，抽吸管路30靠近待清洁表面设置，抽吸管路30具有入口和出口，抽吸管路30的入口设置于待清洁表面的上方；抽吸管路30的出口连接有回收箱90，回收箱90还与风机流体流通，风机能够 提供负压，用于将污渍从抽吸管路30的入口抽吸至回收箱90中，从而起到回收污渍的作用。
污渍回收器还包括有吸嘴，吸嘴的数量和尺寸均与抽吸管路30的入口相匹配，使得吸嘴能够装配于抽吸管路30的入口。其中，吸嘴设置在前滚刷10和后滚刷20之间的间隙的上方，或吸嘴设置在待清洁表面的上方，用于抽吸前滚刷10和后滚刷20之间的污浊液体和/或待清洁表面的污浊液体。抽吸到的污浊液体经由抽吸管路30输送至回收箱90内。抽吸管路30可以为按照路径延伸的硬管，或者可以改变路径的软管，具体可根据手持清洗设备的类型以及结构设计而选择。
因此，本公开的手持清洗设备不仅可以清洗待清洁表面，还能够同时回收清洗后的污渍。
如图6、图8和图9所示，在本实施例的手持清洗设备还包括流体分配器180，流体分配器180用于将清洁液分配至不同的滚刷或待清洁表面。流体分配器180是一种可以控制清洁液体的装置，清洁液体是包括清水、清洗剂、清水与清洗剂的混合液的任一种。流体分配器180可以将液体喷洒至待清洁表面，进而利用滚刷进行清洁。流体分配器180包括流体入口1802、流体分配通道1803和至少两个流体出口1801；流体入口1802与输水管路130连接，流体分配通道1803将流入的流体分配到至少两个流体出口1801。
所有的流体出口1801都间隔相同距离设置，使得最终输出的清洁液能够均匀覆盖在滚刷或待清洁表面；流体入口1802与每条流体分配通道的入口1804连通，以将清洁液输送至每条流体分配通道1803中，而每条流体分配通道1803的出口都对应连通一个流体出口1801，同时每条流体分配通道的入口1804至出口的距离均相同，使得每个流体出口1801输出清洁液的时间和水量一致，保证流体分配器180将清洁液均匀分配至滚刷或待清洁表面。
输水管路130远离待清洁表面设置，且位于前滚刷10和后滚刷20的上方，输水管路130的一端还与清洁液箱220连接，输水管路130的另一端设置于滚刷上远离待清洁表面的一侧，与流体分配器180的流体入口1802连通，最终将清洁液输送至滚刷或待清洁表面。输水管路130可以为按照路径延伸的硬管，或者可以改变路径的软管，具体可根据手持清洗设备的类型以及结构设计而选择。
如图7、图8和图9所示，输水管路130包括导水管1302和至少两个分水管1301；导水管1302的一端连接有清洁液箱220，导水管1302的另一端分流，使得导水管1302的另一端与两个分水管1301连通。两个分水管1301的输出端分别位于前滚刷10和后滚刷20的上方，从而将清洁液输送至前滚刷10和后滚刷20。
在本实施例中，利用至少两个分水管1301可保证清洁液能够被分流，以提高清洁液的喷洒面积，从而提高了清洁喷洒的全面性及喷洒效率。
分水管1301的输出端还设置有至少一个喷嘴，清洁液箱220通过分水管1301与喷嘴连通，以将清洁液箱220内的流体通过分水管1301输送给喷嘴处，进而向前滚刷10、后 滚刷20和/或待清洁表面喷洒流体。
在具体应用中，喷嘴可提高清洁液喷洒的面积及喷洒的均匀性。喷嘴的数量可由前滚刷10和后滚刷20的整体长度而设计，并且相邻的两个喷嘴之间的距离相同，从而保证滚刷的各个部分均能被喷洒到清洁液。
如图7所示，导水管1302连接有清洁液箱220的一端还连接有水泵210，水泵210将清洁液箱220中的清洁液抽吸至导水管1302中，导水管1302又将清洁液分流至两个分水管1301中。水泵210可增加清洁液的流动速度，缩短清洁液流至分水管1301的时间，从而提高手持清洗设备的工作效率。
输水管路130包括四个分水管1301。其中两个分水管1301的输出端位于前滚刷10的两侧，另外两个分水管1301的输出端位于后滚刷20的两侧，能够将清洁液均匀的分配至前滚刷10和后滚刷20上。
每个滚刷配置有两个分水管1301，这样通过两个分水管1301同时对一个滚刷喷洒清洁液，从而提高了清洁液喷洒的效率，并且两个分水管1301的输出端位于该滚刷的两侧，也减小或者避免了两个分水管1301喷洒区域相重合的现象出现，提高喷洒的均匀性。
如图2和图3所示，在本实施例的手持清洗设备还包括至少一个刮条，刮条与滚刷的外周靠近或相接触，用于刮除滚刷外周残留的清洁液或污渍；或刮条设置于滚刷外周，且与待清洁表面接触，用于刮除待清洁表面残留的清洁液或污渍。
刮条可刮除滚刷外周残留的清洁液或污渍，以及待清洁表面残留的清洁液或污渍，从而能够提高滚刷的清洁度，以避免滚刷上的污渍或者过多的清洁液通过离心力甩出，对清洁面造成二次污染；并且辅助滚刷对待清洁表面进行清洁，提高清洁效果。
刮条与滚刷的外周呈一定角度设置，且刮条与滚刷的外周过盈接触。
刮条与滚刷的外周呈一定角度设置，这样能够增加刮条对滚刷的阻力，从而提高对滚刷的刮除效果。过盈接触使得刮条紧密贴靠于滚刷的外周，能够更好的清理附着于滚刷外周的污渍或清洁液，进一步提高对滚刷的清洁效果。
刮条的一种设置方式为：刮条位于滚刷的上方，当刮条设置于滚刷的外周，用于刮除滚刷外周残留的清洁液或污渍时，刮条位于前滚刷10和后滚刷20的上方，即为上刮条50，图3是本公开的实施例提供的表面行走部的剖面示意图，请查看图3，其中，前滚刷10和后滚刷20的外周均安装有上刮条50，且上刮条50靠近抽水管路30的入口或喷嘴设置，用于在抽吸之前，刮除前滚刷10和后滚刷20上残留的清洁液或污渍，或者在同一区域基本同时刮除和抽吸，从而提高前滚刷10及后滚刷20的清洁度，以避免滚刷上的污渍或者过多的清洁液通过离心力甩出，对清洁面造成二次污染，提高了清洁效果。
上刮条50与前滚刷10和后滚刷20的外周均呈一定角度设置，且与前滚刷10和后滚刷20的外周过盈接触。过盈接触使得上刮条50紧密贴靠于前滚刷10和后滚刷20的外周，能够更好的清理附着于滚刷外周的污渍或清洁液，进一步提高对前滚刷10和或后滚刷20的清洁效果。
刮条包括污渍刮条，污渍刮条用于刮除滚刷外周残留的清洁液或污渍，即上刮条50包括污渍刮条，污渍刮条用于刮除滚刷外周残留的清洁液或污渍。
在一实施例中，如图2和图3所示，刮条配置为两个，分别为第一刮条501及第二刮条502。其中，第一刮条501与前滚刷10的外周呈一定角度设置；且第一刮条501与前滚刷10过盈接触，使第一刮条501与前滚刷10充分接触，从而增强第一刮条501对后滚刷10的清洁效果。同样地第二刮条502与后滚刷20的外周呈一定角度设置；且第二刮条502与后滚刷20过盈接触，使第二刮条502与后滚刷20充分接触，从而增强第二刮条502对后滚刷20的清洁效果。刮条表面与滚刷的旋转运动的线速度方向，也即投射到圆周的切线方向成锐角，这样增加刮条对滚刷的阻力，从而提高对滚刷的刮除效果。
如图2和图3所示，第一刮条501包括第一污渍刮条5011，第一污渍刮条5011安装在位于前滚刷10上方的流体分配器180的第一侧，第一污渍刮条5011与前滚刷10的外周呈一定角度设置且第一污渍刮条5011与前滚刷10过盈接触；第二刮条502包括第二污渍刮条5021，第二污渍刮条5021安装在位于后滚刷20上方的流体分配器180的第一侧，第二污渍刮条5021与后滚刷20的外周呈一定角度设置且第二污渍刮条5021与前滚刷20过盈接触，其中，流体分配器180的第一侧为流体分配器180的沿长度方向的两侧中的任意一侧。
清洁液从流体分配器180流出后随滚刷转动落在待清洁表面，在随着滚刷和地面的摩擦和地面污渍充分混合，并进一步随着滚刷转动被携带和抽吸管道的吸力被抽吸到达抽吸管路30的入口，并在污渍刮条50的刮擦下进一步被刮除和被抽吸进入抽吸管路30，最终进入回收箱90内。由此，利用第一污渍刮条5011和第二污渍刮条5021可避免附着避免前滚刷10和后滚刷20上的污渍或者脏水通过离心力甩出，对清洁面造成二次污染。
第一污渍刮条5011及第二污渍刮条5021均采用硬质材料制成，能够提供较大的刮擦力，从而刮掉前滚刷10或后滚刷20上较难去除的污渍，增强刮除效果。其中，硬质材料包括但不限于塑料等。
进一步地，刮条还包括蓄水刮条，蓄水刮条用于使清洁液与滚刷充分接触，即上刮条50还包括污渍刮条，污渍刮条用于刮除滚刷外周残留的清洁液或污渍。
第一刮条501还包括第一蓄水刮条5012，第一蓄水刮条5012安装在位于前滚刷10上方的流体分配器180的第二侧，第一蓄水刮条5012与前滚刷10的外周呈一定角度设置且第一蓄水刮条5012与前滚刷10过盈接触；第二刮条502包括第二蓄水刮条5022，第二蓄水刮条5022安装在位于后滚刷20上方的流体分配器180的第二侧，第二蓄水刮条5022与后滚刷20的外周呈一定角度设置且第二蓄水刮条5022与后滚刷20过盈接触，其中，流体分配器180的第二侧为与第一侧相对的一侧。
在前滚刷10经由第一污渍刮条5011刮除附着在上面的污渍和脏水后，干净的清洁液流到前滚刷10，再经由第一蓄水刮条5012的刮擦，使前滚刷10将喷洒在前滚刷10上的清洁液更加充分的吸收，从而形成前滚刷10在使用过程中的自清洁循环，这样不仅能够 提高前滚刷10的清洁度，又能提高前滚刷10对待清洁表面的清洗效果。同样地，在后滚刷20经由第二污渍刮条5021刮除附着在上面的污渍和脏水后，干净的清洁液流到后滚刷20，再经由第二蓄水刮条5022的刮擦，使后滚刷20将喷洒在后滚刷20上的清洁液更加充分的吸收，从而形成后滚刷20在使用过程中的自清洁循环，这样不仅能够提高后滚刷20的清洁度，又能提高后滚刷20对待清洁表面的清洗效果。
第一蓄水刮条5012和第二蓄水刮条5022采用软质材料制成，软质材料提供较小的刮擦力，以避免将清洁液刮下。其中，软质材料包括但不限于橡胶、金属弹片等。
在一实施例中，如图11所示，第一污渍刮条5011、第二污渍刮条5021、第一蓄水刮条5012和第二蓄水刮条5022均包括一体连接的接触部230和连接部240，连接部240和接触部230形成为具有弹性的薄片，使得接触部230在与前滚刷10或后滚刷20的外周接触时，能够较为平滑刮除前滚刷10或后滚刷20的外周残留的污渍或多余的清洁液。
本实施例的手持清洗设备还包括相匹配连接的壳体70，壳体70具有一容纳空间。前滚刷10和后滚刷20的部分结构安装于壳体70的容纳空间内，前滚刷10和后滚刷20的剩余部分结构突出于壳体70外并与待清洁表面接触，用于清理待清洁表面。壳体70包括可拆卸连接的上盖和下壳体70，从而便于用户或工作人员对壳体70内部件的检查及维修，上盖用于封闭下壳体70的同时还与直立部150连接。其中，可拆卸连接可通过卡接或螺栓230连接等现有的可拆卸连接的形式实现，本实施例不做严格限定。
刮条的另一种设置方式为：如图2和图3所示，当刮条设置于滚刷外周且与待清洁表面接触，用于刮除待清洁表面残留的清洁液或污渍时，刮条位于前滚刷10和后滚刷20的下方，即为下刮条60，其中，下刮条60的一端安装于壳体70上，且靠近后滚刷20突出于壳体70外的剩余部分结构设置；下刮条60的另一端突出壳体70外，在手持清洗设备沿着待清洁表面移动时，下刮条60能够与待清洁表面接触，同时能够刮除待清洁表面的污渍，起到进一步清理待清洁表面的作用。
如图2、图3和图12所示，下刮条60也包括一体连接的接触部230和连接部240，接触部230形成为具有弹性的薄片，使得接触部230在与待清洁表面接触时，能够较为平滑地刮除待清洁表面的污渍或多余的清洁液。
本实施例的手持清洗设备还包括滚刷驱动齿轮箱40，滚刷驱动齿轮箱40分为前滚刷驱动齿轮箱和后滚刷驱动齿轮箱，前滚刷驱动齿轮箱与前滚刷10传动连接，用于带动前滚刷10转动；后滚刷驱动齿轮箱与后滚刷20传动连接，用于带动后滚刷20转动。
前滚刷驱动齿轮箱在第二电机的驱动下传动至前滚刷10，从而驱动前滚刷10转动；后滚刷驱动齿轮箱与后滚刷20之间通过皮带110传动。第一电机驱动后滚刷20驱动齿轮箱工作，从而带动皮带110转动，皮带110将带动后滚刷20转动。在本实施例中，通过滚刷齿轮箱40进行传动，以带动前滚刷10及后滚刷20转动，这样能够保证传动的稳定可靠，并且传动功率较高。
其中，前滚刷驱动齿轮箱内至少设置两个相互啮合的齿轮，其中一个齿轮作为主齿轮 与第二电机连接，另一个作为从动齿轮与前滚刷的转动连接，这样第二电机带动主齿轮转动，从而带动从动齿轮一起转动，这样就带动前滚刷10转动。
后滚刷驱动齿轮箱内至少设置两个相互啮合的齿轮，其中一个齿轮作为主齿轮与第一电机连接，另一个作为从动齿轮与后滚刷的转动连接，这样第一电机带动主齿轮转动，从而带动从动齿轮一起转动，这样就带动后滚刷20转动。
滚刷驱动齿轮箱40的外部箱体可以使用吸音材质制造，降低滚刷驱动齿轮箱40工作过程中产生的噪音。
图4是本公开的实施例提供的手持清洗设备的电路示意图，请查看图4，本实施例的手持清洗设备还包括：姿态传感器100、控制电路200和滚刷驱动电路80。
姿态传感器100用于感应手持清洗设备的运动方向信息，并将运动方向信息传输至控制电路200。姿态传感器100为六轴传感器，六轴传感器能够实时获取本实施例的刷头的加速度数据，同时由于本实施例中手持清洗设备在向前移动和前后移动时的加速度数据不同，因此通过六轴传感器实时获取到的不同加速度数值能够判断手持清洗设备的运动方向是向前还是向后。
其中，控制电路200可以使用各种应用专用集成电路(140SIC)、数字信号处理器(DSP)、数字信号处理设备(DSPD)、可编程逻辑器件(PLD)、现场可编程门阵列(FPG140)、微中控元件、微处理器或其他电子元件实现。控制电路200通过通信接口与六轴传感器连接，从而获取六轴传感器检测到的加速度数据，通过加速度数据判断手持清洗设备的运动方向信息。同时，控制电路200还与滚刷驱动电路80电连接，根据获取的手持清洗设备的运动方向信息控制滚刷驱动电路80，使得滚刷驱动电路80驱动滚刷驱动齿轮箱40转动。
滚刷驱动齿轮箱40包括前滚刷10驱动齿轮箱和后滚刷20驱动齿轮箱，当手持清洗设备的运动方向信息为向前移动时，控制电路200控制前滚刷10驱动齿轮箱的转速大于后滚刷20驱动齿轮箱，从而使得前滚刷10的转速大于后滚刷20的转速；当手持清洗设备的运动方向信息为向后移动时，控制电路200控制后滚刷20驱动齿轮箱的转速大于前滚刷10驱动齿轮箱，从而使得后滚刷20的转速大于前滚刷10的转速，进而使得本公开的手持清洗设备向前移动时有前助力，向后移动时有后助力，以减小用户移动手持清洗设备的推拉力。
手持清洁设备还包括液位传感器，液位传感器安装在所述手持清洁设备的清洁液箱220、回收箱90或者输水管路130的中一个或几个上；液位传感器与控制电路连接，液位传感器用于感应手持清洗设备的液位信息，并将液位信息传输至所述控制电路200。
在液位传感器设置在污渍回收器的回收箱90中的情况下，液位传感器用于检测回收箱90中的流体液位。具体而言，液位传感器可实时检测回收箱90内的流体液位值，控制电路200将液位传感器所检测的流体液位值与第一液位阈值进行比较，如果流体液位值大于或等于第一液位阈值，则控制电路200可启动手持清洗设备上的提示装置或报警装置进 行提示或报警，从而提醒用户停止使用手持清洗设备，避免流体从回收箱90内溢出。
在该实现方式中，液位传感器为非接触式传感器或接触式传感器。非接触式传感器为电容式传器。
接触式传感器包括正电极及负电极，正电极及负电极伸入至回收箱90内；控制电路220分别与正电极及负电极电连接，且正电极与负电极伸入至回收箱90内。在电极与流体接触时，正电极和负电极通过流体导通，控制电路200确定回收箱90的流体液位值大于或等于第一液位阈值，从而控制电路200控制手持清洗设备停止工作并报警。
电容式传感器在随着流体远离或靠近，电容式传感器的电容发生变化，也就是说无流体靠近时，电容式传感器存在较小的寄生电容，而当流体靠近时，寄生电容发生改变，根据寄生电容的变化可实现对流体输出管路内是否有流体的检测。
控制电路200将产生的实时感应电容值与环境感应电容值做差值，其中，环境感应电容为回收箱90内没有流体时所产生的感应电容值，然后控制电路200将该差值与预设阈值比较，若该差值大于或等于预设差值，则判定回收箱90内的流体液位值大于或等于第一液位阈值，从而控制电路220控制手持清洗设备停止工作并报警。
在手持清洗设备使用过程中，流体分配器180中的流体可能会随着使用时长的增加而减少，因此本公开实施例中，液位传感器设置在清洁液箱220内，用于检测清洁液箱220的流体液位。
液位传感器可实时检测清洁液箱220的流体液位值，控制电路200将液位传感器所检测的流体液位值与第二液位阈值进行比较，如果流体液位值小于第二液位阈值，则控制电路200可启动手持清洗设备上的提示装置或报警装置进行提示或报警，从而提醒用户补充清洁液，以免影响清洗效果。
或者，液位传感器设置在输水管路130内，用于检测输水管路130内是否有流体。
液位传感器可实时检测输水管路130的流体液位值，控制电路200将液位传感器所检测的流体液位值与第三液位阈值进行比较，如果流体液位值小于第三液位阈值，则控制电路可启动手持清洗设备上的提示装置或报警装置进行提示或报警，从而提醒用户补充清洁液，以免影响清洗效果。
其中，提示装置包括但不限于提示灯，报警装置包括但不限于蜂鸣器或语音播报装置。第二液位阈值和第三液位阈值可由工作人员自行设置，本实施例不做严格限定。
同样地，在该实现方式中，液位传感器为非接触式传感器或接触式传感器。非接触式传感器为电容式传感器。

在液位传感器为电容式传感器时，控制电路200将产生的实时感应电容值与环境感应电容值做差值，其中，环境感应信号为输水管130内没有流体时所产生的感应电容值，然后控制电路200将该差值与预设差值比较，若该差值大于或等于预设阈值，则判定流体输水管路130或清洁液箱220内有流体，从而确定清洁液箱220内存有能够满足清洁作业的流体，然后控制电路200根据该检测结果，控制手持清洗设备继续工作；若该差值小于预设差值，则判定流体输水管路130或清洁液箱220内没有流体，从而确定清洁液箱220内没有存有能够满足清洁作业的流体，然后控制电路200根据该检测结果，控制手持清洗设备停止工作并报警。
