具体实施方式
下面参照图1-图15详细描述根据本申请实施例的表面清洁装置的地刷组件2。需要说明的是，表面清洁装置可以为吸尘器或干湿两用吸尘器。
如图2-图4所示，根据本申请实施例的表面清洁装置的地刷组件2，包括地刷壳体21、滚刷22和流体供应组件23。
具体而言，地刷壳体21具有腔室，滚刷22设于地刷腔室211内，流体供应组件23与地刷壳体21连接。这里的“流体供应组件23”可以指供应液体或气体的部件，例如，其可以为地刷组件2提供水、带有清洁剂的液体或者水蒸气等，流体供应组件23包括第一喷射口231和第二喷射口232，第一喷射口231可以用于朝向滚刷22喷射流体，第二喷射口232可以用于朝向被清洁表面喷射流体。
需要说明的是，当被清洗表面上的污渍难以清除时，可以使第一喷射口231或第二喷射口232对准污渍，并向污渍上喷射流体(例如水、水蒸气)，流体可以浸润、软化污渍，流体喷射时所带来的冲击力，对污渍还具有清洗、冲刷的作用，当滚刷22经过污渍时，可以很容易的将污渍清除掉、将被清洁表面清洁干净。
另外，还值得注意的是，在设置第一喷射口231和第二喷射口232时，可以将第一喷射口231的喷射方向、第二喷射口232的喷射方向设置为不同的喷射方向，例如，第一喷射口231的喷射方向可以设置为朝向滚刷22喷射，用于打湿滚刷22，当滚刷22沾有流体(例如滚刷22为湿漉的状态)时，有利于利用滚刷22将被清洁表面的杂物、污渍清洁干净；再如，第二喷射口232的喷射方向可以设置为朝向被清洁表面，用于打湿被清洁表面，当滚刷22经过有污渍的被清洁的表面时，滚刷22可以将污渍带走，同时将被清洁表面擦干净。
根据本申请实施例的表面清洁装置的地刷组件2，通过设置朝向滚刷22喷射流体第一喷射口231、设置朝向被清洁表面喷射流体的第二喷射口232，可以利用第一喷射口231喷出的流体打湿滚刷22、利用第二喷射口232喷出的流体清洗、冲刷、软化污渍，当滚刷22经过污渍时，可以轻松地将污渍清洁掉，不但方便操作，还可以提升表面清洁装置的清洁性能，使其可以对具有污渍的地方进行着重清洗。
如图4-图5所示，根据本申请的一些实施例，第一喷射口231的直径可以为L1，其中1.5mm≤L1≤2.5mm。经过实验验证，当第一喷射口231的直径的取值范围是1.5mm-2.5mm时，地刷组件2的清洁效果更好、喷嘴不易堵塞、流体冲击力强。进一步地，经过试验验证，当L1＝1.7mm、L1＝1.9mm、L1＝2.1mm或L1＝2.3mm时，不但便于设置第一喷射口231，还可以优化地刷组件2的清洁性能。
在本申请的一些实施例中，第一喷射口231可以呈扁口，由此从第一喷射口231喷出 的流体呈扇形散射状，从而可以使流体覆盖较大的区域，进而可以减少第一喷射口231的数量，以达到简化地刷组件2的目的。同时，扁口形状的喷射口还可以提升流体的冲击力，从而可以提升地刷组件2的清洁能力。
根据本申请的一些实施例，如图5所示，流体供应组件23可以包括第一管路24和第二管路25。其中，第一管路24的一端与第一喷射口231连通，以为第一喷射口231供流体，第一管路24嵌设于地刷壳体21，第二管路25的一端与第二喷射口232连通，以为第二喷射口232供流体，第二管路25嵌设于地刷壳体21。
如图2所示，根据本申请的一些实施例，地刷壳体21设有第一流水通道26和第二流水通道27。需要说明的，第一流水通道26和第二流水通道27可以是开设于地刷壳体21的管道结构或槽体结构，第一喷射口231设于第一流水通道26，第二喷射口232设于第二流水通道27。由此，可以利用地刷壳体21的自身结构构造通道，为相应的喷射口供流体，进而可以简化地刷组件2的结构，减少部件数量，不但可以节约生产成本，还可以减轻地刷组件2的重量。
如图4-图5所示，根据本申请的一些实施例，第二喷射口232的直径可以为L2，其中1.5mm≤L2≤1.8mm。经过实验验证，当第二喷射口232的直径的取值范围是1.5mm-1.8mm时，地刷组件2的清洁效果更好、喷嘴不易堵塞、流体冲击力强，对污渍的定点清洁性能更优。进一步地，经过试验验证，当L1＝1.7mm或L1＝1.6mm时，不但便于设置第二喷射口232，还可以优化地刷组件2的清洁性能。
在本申请的一些实施例中，第二喷射口232可以呈扁口，由此从第二喷射口232喷出的流体呈扇形散射状，从而可以使流体覆盖较大的区域，进而可以减少第二喷射口232的数量，以达到简化地刷组件2的目的。同时，扁口形状的喷射口还可以提升流体的冲击力，从而可以提升地刷组件2的清洁能力。
为了提升第一喷射口231的喷射效率，使从第一喷射口231喷出的流体能够尽快打湿滚刷22，在本申请的一些实施例中，第一喷射口231的喷射方向可以与滚刷22正对。为了方便第二喷射口232能够准确地喷射到被清洗表面，可以调整第二喷射口232的喷射角度，例如，在本申请的一些实施例中，第二喷射口232的喷射方向与被清洁表面之间的夹角为α，其中30°≤α≤45°。由此可以定点定向集中喷洒流体(如水或水蒸气)，使流体直接清理地面顽固污渍。
在本申请的一些实施例中，第一喷射口231可以为多个，多个第一喷射口231沿滚刷22的长度方向间隔开，由此可以提升喷湿滚刷22的速度，提升滚刷22清洁的效率。在本申请的一些实施例中，第二喷射口232可以为多个，多个第二喷射口232沿滚刷22的长度方向间隔开，由此可以增大喷射面积，提升第二喷射口232的喷射效率，使其可以覆盖污 渍。
在本申请一些实施例中，流体供应组件23可以包括水箱或蒸汽发生器。需要说明的是，当流体供应组件23包括水箱时，第一喷射口231和第二喷射口232可以喷射出水或者混合有洗涤剂的水，从而便于打湿滚刷22、清洗污渍；当流体供应组件23包括蒸汽发生器时，第一喷射口231和第二喷射口232可以喷射出水蒸气，从而便于打湿滚刷22、软化污渍。
根据本申请实施例的表面清洁装置，包括如上所述的表面清洁装置的地刷组件2。
根据本申请实施例的表面清洁装置，通过设置朝向滚刷22喷射流体第一喷射口231、设置朝向被清洁表面喷射流体的第二喷射口232，可以利用第一喷射口231喷出的流体打湿滚刷22、利用第二喷射口232喷出的流体清洗、冲刷、软化污渍，当滚刷22经过污渍时，可以轻松地将污渍清洁掉，不但方便操作，还可以提升表面清洁装置的清洁性能，使其可以对具有污渍的地方进行着重清洗。
下面参考图1-图23详细描述根据本申请实施例的表面清洁装置100。需要说明的是，表面清洁装置100可以为吸尘器或干湿两用吸尘器。
如图9-图10所示，根据本申请实施例的表面清洁装置100，包括机身1、地刷壳体21、滚刷22、流体供应组件23和控制电路234。用于控制是否为第一喷射口231、第二喷射口232供流体的控制电路234。
具体而言，地刷壳体21与机身1连接，地刷壳体21具有地刷腔室211，滚刷22设于地刷腔室211内，流体供应组件23与机身1连接，流体供应组件23可以包括向滚刷22喷射流体的第一喷射口231231和向被清洁表面喷射流体的第二喷射口232，控制电路234可以控制流体通过第一喷射口231和/或第二喷射口232喷出。也就是说，控制电路234可以控制流体仅通过第一喷射口231喷出，控制电路234也可以控制流体仅通过第二喷射口232喷出，控制电路234还可以控制流体同时通过第一喷射口231和第二喷射口232喷出。。
例如，当需要利用第一喷射口231对滚刷22进行打湿时，可以利用控制电路234使流体供应组件23第一喷射口231供流体；当需要利用第二喷射口232对被清洁表面进行打湿时，可以利用控制电路234使流体供应组件23对第二喷射口232供流体；当需要利用第一喷射口231、第二喷射口232同时喷射流体时，可以利用控制电路234使流体供应组件23对第一喷射口231、第二喷射口232同时供流体，由此用户可以根据需求使用表面清洁装置100。
根据本申请实施例的表面清洁装置100，通过设置控制电路234，可以控制第一喷 射口231和第二喷射口232的工作状态，从而可以实现定点定向集中喷洒流体(例如水、水蒸气、或混合有洗涤剂的水)，以直接指向被清洁表面的污垢，易将污垢清洗干净，进而可以提升表面清洁装置100的清洁性能。
根据本申请的一些实施例，表面清洁装置100可以包括水泵233，水泵233可以用于将流体泵入至第一喷射口231和第二喷射口232中的至少一个。需要说明的是，当需要利用第一喷射口231喷出流体时，可以利用水泵233将流体泵入到第一喷射口231；当需要利用第二喷射口232喷出流体时，可以利用水泵233将流体泵入到第二喷射口232；当需要利用第一喷射口231和第二喷射口232同时喷流体时，可以利用水泵233将流体同时泵入到第一喷射口231和第二喷射口232。
为方便控制水泵233，水泵233可以与控制电路234电连接，控制电路234可以包括用于控制水泵233与控制电路234之间通断的按键组件。可以理解的是，按键组件可以电连接在水泵233和控制电路234之间，用于控制水泵233和控制电路234之间的通断，当按键组件闭合时，水泵233和控制电路234之间连通，水泵233可以工作；当按键组件断开时，水泵233和控制电路234之间断开，水泵233不工作。
在一些实施例中，按键组件可以为常开开关，由此便于控制水泵233和控制电路234之间的通断。在一些实施例中，按键组件可以设于机身1上，由此便于用户操作。进一步地，为方便用户操作，如图10、图11所示，按键组件可以设于机身1的把手处(或者按键组件可以设于机身1上端)。
根据本申请的一些实施例，流体供应组件23可以包括水路系统28和用于控制第一喷射口231和第二喷射口232通断的控制阀282。其中，机身1和地刷壳体21中的至少一个与水路系统28连接，第一喷射口231和第二喷射口232均设在水路系统28内。换言之，机身1和地刷壳体21中的至少一个与水路系统28连接，由此可以优化表面清洁装置100的结构布局。例如，如图9所示，水路系统28可以设于机身1上。如图10所示，控制阀282与控制电路234电连接，控制电路234可以给控制阀282发送电信号。在一些实施例中，控制阀282可以设于地刷壳体21或机身1。
根据本申请的一些实施例，流体供应组件23可以包括水箱236和用于控制第一喷射口231和第二喷射口232通断的控制阀282。其中，水箱236与机身1和地刷壳体21中的至少一个连接。换言之，机身1和地刷壳体21中的至少一个与水箱236连接，由此可以优化表面清洁装置100的结构布局。例如，如图9所示，水箱236设于机身1上。如图10所示，控制阀282与控制电路234电连接，控制电路234可以给控制阀282发送电信号。在一些实施例中，控制阀282可以设于地刷壳体21或机身1。
需要说明的是，控制阀282可以具有不同状态，可以通过改变控制阀282的状态来控制第一喷射口231和第二喷射口232的通断。例如，控制阀282包括第一状态、第二状态和第三状态，当用户仅需要使用第一喷射口231可以将控制阀282设置成第一状态，此时仅有第一喷射口231处于连通状态，第一喷射口231可以向滚刷22喷射流体，而此时第二喷射口232处于断开状态；当用户仅需要使用第二喷射口232可以将控制阀282设置成第二状态，此时仅有第二喷射口232处于连通状态，第二喷射口232可以向被清洁表面喷射流体，而此时第一喷射口231处于断开状态；当用户需要同时使用第一喷射口231和第二喷射口232时，可以将控制阀282设置成第三状态，此时第一喷射口231、第二喷射口232均处于连通状态，第一喷射口231可以向滚刷22喷射流体，第二喷射口232可以向被清洁表面喷射流体。
为方便用户操作，可以将用于切换控制阀282状态的部件设置成踩踏的部件或拨动部件，拨动或踩踏该部件时，控制阀282可以切换至相应的状态。
进一步地，流体供应组件23还可以包括蒸汽发生器。其中，蒸汽发生器与水箱236、第一喷射口231和第二喷射口232均连通。需要说明的是，蒸汽发生器为可以产生水蒸气或具有预定温度的水蒸气的装置，水箱236可以为蒸汽发生器供水，蒸汽发生器产生的水蒸气或具有预定温度的水蒸气可以从第一喷射口231或第二喷射口232喷出。
为方便设置第一喷射口231和第二喷射口232，流体供应组件23还可以包括第一管路24和第二管路25。其中，第一管路24具有第一喷射口231，第二管路25具有第二喷射口232，第一管路24嵌设于地刷壳体21，第二管路25嵌设于地刷壳体21内。具体地，水泵233可以通过第一管路24与第一喷射口231连通，以为第一喷射口231供流体，水泵233还可以通过第二管路25与第二喷射口232连通，以为第二喷射口232供流体。
如图2所示，根据本申请的一些实施例，地刷壳体21设有第一流水通道26和第二流水通道27。需要说明的，第一流水通道26和第二流水通道27可以是开设于地刷壳体21的管道结构或槽体结构，第一喷射口231设于第一流水通道26，第二喷射口232设于第二流水通道27。由此，可以利用地刷壳体21的自身结构构造通道，为相应的喷射口供流体，进而可以简化地刷组件2的结构，减少部件数量，不但可以节约生产成本，还可以减轻地刷组件2的重量。
如图4、图5所示，根据本申请的一些实施例，第一喷射口231的直径可以为L1，其中1.5mm≤L1≤2.5mm。经过实验验证，当第一喷射口231的直径的取值范围是1.5mm-2.5mm时，地刷组件2的清洁效果更好、喷嘴不易堵塞、流体冲击力强。进一 步地，经过试验验证，当L1＝1.7mm、L1＝1.9mm、L1＝2.1mm或L1＝2.3mm时，不但便于设置第一喷射口231，还可以优化地刷组件2的清洁性能。
在本申请的一些实施例中，第一喷射口231可以呈扁口，由此从第一喷射口231喷出的流体呈扇形散射状，从而可以使流体覆盖较大的区域，进而可以减少第一喷射口231的数量，以达到简化地刷组件2的目的。同时，扁口形状的喷射口还可以提升流体的冲击力，从而可以提升地刷组件2的清洁能力。
如图4、图5所示，根据本申请的一些实施例，第二喷射口232的直径可以为L2，其中1.5mm≤L2≤1.8mm。经过实验验证，当第二喷射口232的直径的取值范围是1.5mm-1.8mm时，地刷组件2的清洁效果更好、喷嘴不易堵塞、流体冲击力强，对污渍的定点清洁性能更优。进一步地，经过试验验证，当L1＝1.7mm或L1＝1.6mm时，不但便于设置第二喷射口232，还可以优化地刷组件2的清洁性能。
在本申请的一些实施例中，第二喷射口232可以呈扁口，由此从第二喷射口232喷出的流体呈扇形散射状，从而可以使流体覆盖较大的区域，进而可以减少第二喷射口232的数量，以达到简化地刷组件2的目的。同时，扁口形状的喷射口还可以提升流体的冲击力，从而可以提升地刷组件2的清洁能力。
为了提升第一喷射口231的喷射效率，使从第一喷射口231喷出的流体能够尽快打湿滚刷22，在本申请的一些实施例中，第一喷射口231的喷射方向可以与滚刷22正对。为了方便第二喷射口232能够准确地喷射到被清洗表面，可以调整第二喷射口232的喷射角度，例如，在本申请的一些实施例中，第二喷射口232的喷射方向与被清洁表面之间的夹角为α，其中30°≤α≤45°。
在本申请的一些实施例中，第一喷射口231可以为多个，多个第一喷射口231沿滚刷22的长度方向间隔开，由此可以提升喷湿滚刷22的速度，提升滚刷22清洁的效率。需要说明的是，多个第一喷射口231中的部分第一喷射口231可以喷出未混合有清洁剂的液体，多个第一喷射口231中的另一部分第一喷射口231可以喷出混合有清洁剂的液体，另外通过设置具有切换状态的控制阀282，还可以控制部分第一喷射口231喷出未混合有清洁剂的液体，控制另一部分第一喷射口231喷出混合有清洁剂的液体。由此，用户可以根据需求控制第一喷射口231喷出的流体的种类。
在本申请的一些实施例中，第二喷射口232可以为多个，多个第二喷射口232沿滚刷22的长度方向间隔开，由此可以增大喷射面积，提升第二喷射口232的喷射效率，使其可以覆盖污渍。需要说明的是，多个第二喷射口232中的部分第二喷射口232可以喷出未混合有清洁剂的液体，多个第二喷射口232中的另一部分第二喷射口232可以喷 出混合有清洁剂的液体，另外通过设置具有切换状态的控制阀282，还可以控制部分第二喷射口232喷出未混合有清洁剂的液体，控制另一部分第二喷射口232喷出混合有清洁剂的液体。由此，用户可以根据需求控制第二喷射口232喷出的流体的种类。
如图16-图20所示，根据本申请的一些实施例，控制阀282包括：阀体2821、阀芯2822、驱动件2823和多个密封件2824。
具体而言，如图17-图19所示，阀体2821内限定出活动空间，阀体2821的外周壁上设有阀体进水口2821a和多个阀体2821出水口。由此，液体(如水、洗涤剂等)可以从阀体2821进口进入到控制阀282内，并从阀体2821出水口流出阀体2821。
阀芯2822可活动地设在活动空间内，阀芯2822内设有液体流道28221，阀芯2822的外周壁设有与液体流道28221连通的阀芯进水口2822a和阀芯出水口2822b，阀芯进水口2822a始终与阀体进水口2821a连通，阀芯出水口2822b与其中一个阀体2821出水口连通。驱动件2823设在阀芯2822上以驱动阀芯2822活动以使得阀芯出水口2822b与不同的阀体2821出水口切换连通。由此，可以通过驱动件2823驱动阀芯2822在活动空间内的移动，可以切换与阀芯出水口2822b相对的阀体2821出水口，使对应的阀体2821出水口出水，以满足表面清洁装置100不同工作模式下的水路流动需求。
多个密封件2824设在阀芯2822的外周壁上且与活动空间的内壁接触，阀芯进水口2822a的两侧、阀芯出水口2822b的两侧均分布有密封件2824。由此，通过在阀芯进水口2822a和阀芯出水口2822b的两侧设置密封件2824，可以提高控制阀282的密封性，防止控制阀282漏水。
由此，通过驱动件2823可以控制阀282芯在阀体2821的活动空间内移动，以切换阀芯出水口2822b与不同的阀体2821出水口连通，从而使对应的阀体2821出水口出水，以满足表面清洁装置100不同工作模式下的水路流动需求。而且，该控制阀282结构简单、操作方便。
如图17-图20所示，根据本申请的一些实施例，阀芯2822可以沿阀芯2822的长度方向可移动地设在活动空间内，在阀芯2822的长度方向上，阀芯进水口2822a的长度大于阀体进水口2821a的长度，多个阀体2821出水口沿阀芯2822的长度方向间隔设置。需要说明的是，通过设置阀芯进水口2822a的长度大于阀体进水口2821a的长度，当阀芯2822在阀体2821内的活动空间内沿阀芯2822的长度方向移动时，可以使阀体进水口2821a与阀芯进水口2822a始终相对，从而可以使液体不断经过阀体进水口2821a和阀芯进水口2822a进入到阀芯2822的液体流道28221内。
在本申请的一些实施例中，阀体进水口2821a可以位于多个阀体2821出水口的一 侧。如图17-图20所示，阀体进水口2821a可以位于多个阀体2821出水口的上侧(如图17-图20中所示的上下方向)，由此，从阀体进水口2821a进入到液体流道28221内的液体可以在自身的重力作用下朝向多个阀体2821出水口流动。当然，阀体进水口2821a也可以设于多个阀体2821出水口的下侧，从阀体进水口2821a进入到液体流道28221内的液体可以借助外力驱动朝向多个阀体2821出水口流动。
根据本申请的一些实施例，控制阀282还可以包括第一弹性件2825，第一弹性件2825设在活动空间的底壁上且与阀芯2822接触以常驱动阀芯2822朝向阀芯进水口2822a的方向移动。如图17-图19所示，在活动空间的底壁上设置有第一弹性件2825，当向下按压驱动件2823时，驱动件2823驱动阀芯2822向下运动，挤压第一弹性件2825使第一弹性件2825产生弹性形变。当停止按压驱动件2823时，在第一弹性件2825的弹性恢复力的作用下，第一弹性件2825驱动阀芯2822复位至初始位置。这里所述的“初始位置”可以理解为，在未按压驱动件2823时，阀芯2822所在的位置。
在本申请的一些实施例中，驱动件2823可以包括按键23231和第二弹性件28232，按键23231设在阀芯2822上且按键23231的一部分位于阀体2821外侧。如图17-图20所示，按键23231设在阀芯2822的上方，当向下按压驱动件2823时，可以驱动阀芯2822向下运动。
第二弹性件28232分别与按键23231和阀体2821接触，按键23231被按压时第二弹性件28232被压缩。由此，当按压按键23231时，按键23231可以挤压第二弹性件28232使第二弹性件28232发生弹性形变。当停止按压按键23231时，在第二弹性件28232的弹性恢复力的作用下，第二弹性件28232可以驱动按键23231复位至初始位置，结构简单、操作方便。
进一步地，按键23231的一部分可以与液体流道28221过盈配合。如图17-图20所示，按键23231的部分可以向下伸入至液体流道28221内，并与液体流道28221过盈配合。由此，可以提高按键23231的装配效率，而且，可以提高按键23231与阀芯2822配合的牢固性和可靠性。
如图17-图20所示，根据本申请的一些实施例，多个密封件2824可以为外套在阀芯2822上的密封圈。由此，便于密封件2824的加工和装配。可以理解的是，通过在阀芯2822的外周壁上外套多个密封圈，密封圈可以止抵于阀体2821的活动空间的内壁与阀芯2822的外壁之间，由此，可以提高控制阀282的密封性，防止控制阀282漏水，
进一步地，如图17-图20所示，阀芯2822的外周壁可以设有多个固定槽28222，多个密封件2824与多个固定槽28222一一对应设置，每个密封件2824固定在相应的固定 槽28222内。由此，通过在阀芯2822的外周壁上设置固定槽28222，便于密封件2824的固定装配，而且，可以避免当阀芯2822在活动空间内移动时，密封件2824从阀芯2822上脱落的问题，结构简单、配合牢固。
在本申请的一些实施例中，阀芯2822的外周壁可以设有缺口28223。如图17-图20所示，沿阀芯2822的长度方向可以间隔设有多个缺口28223，缺口28223可以沿阀芯2822的周向方向延伸。由此，通过在阀芯2822的外周壁上设置缺口28223，可以减小阀芯2822的外周壁与阀体2821的内周壁之间的接触面积，从而可以降低阀芯2822相对于阀体2821运动时的摩擦力，便于对控制阀282的控制。
如图21所示，在本申请的一些实施例中，表面清洁装置100还可以包括驱动器224，驱动器224可以与滚刷22相连以驱动滚刷22转动，流体供应组件23还包括水泵233和喷洒水路281，喷洒水路281可以与水箱236相连，水泵233串联在喷洒水路281上，喷洒水路281上可以设有第一喷射口231和第二喷射口232，由此可以提升表面清洁装置100的清洁效率。
例如，如图21所示，表面清洁装置100包括主机11、滚刷22和水路系统28。如图21所示，主机111可以包括壳体(图中未示出)、风机111、风道件215和收纳容器112，风机111和收纳容器112可以分别设在壳体上。滚刷22可以通过风道件215与壳体连通，驱动器224可以用于驱动滚刷22转动。
当表面清洁装置100工作时，风机111可以进行旋转，由此可以使收纳容器112与外部空气之间形成负压。驱动器224可以驱动滚刷22进行转动，滚刷22在转动时可以将地面擦拭干净，同时还可以将地面上的灰尘和碎屑等污物卷起。在负压的作用下，污物可以沿着风道件215进入到收纳容器112内，从而可以起到清除污物的目的。可选地，滚刷22的外周壁上可以设置多个间隔分布的凸起223，当滚刷22转动时，多个凸起223可以将地面上的碎纸等搅碎，由此可以方便污物进入到收纳容器112内，可以提升表面清洁装置100的清洁效率。
表面清洁装置100还包括安装罩225，安装罩225外罩在滚刷22上，滚刷22的下端的一部分伸出安装罩225。风道件215的下端与安装罩225连通，风道件215的上端与收纳容器112相连通，风机111设在收纳容器112的上端并与收纳容器112相连通。当表面清洁装置100工作时，风机111可以通过转动使收纳容器112与安装罩225之间产生负压，由此可以将滚刷22卷起的灰尘和碎屑等吸入到收纳容器112内。由此，通过上述设置，可以使表面清洁装置100的结构更加简单、可以起到更好的清洁效果。可选地，安装罩225和风道件215可以为一体成型件，由此可以方便装配、减小风道件 215的负压损失。
水路系统28可以包括水箱236、水泵233和喷洒水路281，喷洒水路281可以与水箱236相连，水泵233可以串联在喷洒水路281上，喷洒水路281上设有第一喷射口231和第二喷射口232。具体而言，水箱236内可以存储清洗液，当表面清洁装置100工作时，水泵233可以将水箱236内的清洗液抽入到喷洒水路281内，喷洒水路281内的清洗液可以通过第一喷射口231喷向滚刷22，湿润的滚刷22在转动的过程中可以对地面进行擦拭，从而可以提升表面清洁装置100的清洁效果。
需要进行说明的是，表面清洁装置100可以具有干用和湿用两种工作模式，当表面清洁装置100处于干用工作模式时，水路系统28停止工作。当表面清洁装置100处于湿用工作模式时，水路系统28开始工作，水泵233可以朝向滚刷22供水，用户可以根据实际的使用需求灵活选择。
在本申请的一些实施例中，表面清洁装置100还包括控制装置29，控制装置29可以包括控制板291和操作装置292，控制板291可以分别与驱动器224和水泵233相连，操作装置292可以包括与控制板291相连的自清洁档位，在表面清洁装置100运行且自清洁档位被触发时，控制装置29可以控制水泵233停止运行设定时间后再控制滚刷22停止转动。具体而言，用户可以通过操控操作装置292上的自清洁档位控制驱动器224和水泵233的工作状态。当自清洁档位被触发时，表面清洁装置100可以进入自清洁模式。水泵233首先停止运行、滚刷22继续转动，水箱236停止向滚刷22供水。在离心力的作用下，滚刷22上的清洗液和污渍可以与滚刷22分离并在负压的作用下顺着风道件215进入到收纳容器112内。当水泵233停止工作设定的时间后，滚刷22上的污水和污渍已经清理干净，此时控制装置29控制滚刷22停止转动。
可以理解的是，表面清洁装置100进行自清洁模式的时间可以根据实际的使用需求选择设置，直到滚刷22表面的污水和污渍清理干净为止。例如，表面清洁装置100的自清洁模式的时间可以占表面清洁装置100的工作时间的四分之一。
由此，通过设置控制装置29，控制装置29可以控制表面清洁装置100实现自清洁的功能，滚刷22可以自动清洁，用户无需再将滚刷22拆卸掉进行清洗和晾干，可以大大减轻用户的劳动强度，提升用户的使用体验。表面清洁装置100的结构简单、操作方便，具有很强的实用性。
根据本申请的一些实施例，在自清洁档位被触发且在水泵233停止运行后，可以控制滚刷22增速运行预定时间段后停止转动，由此可以缩短滚刷22的自清洁时间。可以理解的是，当表面清洁装置100进入自清洁模式后，滚刷22加速转动可以增大滚刷22 上的污水和污渍受到的离心力，从而可以提升滚刷22的自清洁效果。
如图21所示，在本申请的一些具体的实施例中，自清洁档位可以为多个，多个自清洁档位对应的水泵233的停止时间点和滚刷22的转速中的至少一个不同，由此可以提升用户的使用灵活性、方便用户的实际操作。在图21所示的具体示例中，操作装置292上设有第一自清洁档位292a和第二自清洁档位292b。其中，第一自清洁档位292a对应的水泵233的停止时间点和第二自清洁档位292b对应的停止时间点相同，但第一自清洁档位292a对应的滚刷22的转速低于第二自清洁档位292b对应的滚刷22的转速。当滚刷22上的污水较多时，可以选择触发第二自清洁档位292b，滚刷22可以进行高速旋转，由此可以节省滚刷22进行自清洁的时间。当滚刷22上的水较少时，则可以选择触发第一自清洁档位292a。当然可以理解的是，操作装置292上的自清洁档位的设置形式不仅限于此，可以根据实际的使用需求选择设置。
如图1所示，在本申请的一些实施例中，自清洁档位可以设在壳体的外周壁上，由此可以方便用户的实际操作。例如，可以在壳体的外周壁上设置操作面板，用户可以通过操作按键23231或者触摸屏的方式选择表面清洁装置100的自清洁档位，从而可以提升用户使用体验。
根据本申请的一些实施例，水箱236和水泵233可以分别设在壳体上，由此可以表面清洁装置100的整体结构更加简单、方便装配。可选地，水箱236可以与壳体组成可拆卸连接。当水箱236内的清洗液用完时，可以将水箱236从壳体上拆卸掉，由此可以方便水箱236加水。进一步地，壳体上可以设置用于支撑水箱236的支撑支架，水箱236可以通过卡扣配合的方式连接在支撑支架上，由此可以使水箱236与壳体之间的配合方式更加简单。
在本申请的一些具体的实施例中，第一喷射口231可以为多个且沿与滚刷22的旋转轴线平行的方向间隔分布，由此可以提升表面清洁装置100的清洁效果。可以理解的是，多个第一喷射口231在滚刷22的轴向方向上间隔分布并同时朝向滚刷22进行喷水，可以使滚刷22表面的湿度更加均匀，进而可以提升滚刷22的清洁效率。
如图22-图23所示，在本申请的一些实施例中，控制阀282可以包括阀体进水口2821a和两个阀体2821出水口(如图22-图23所示的第一阀体出水口2821b和第二阀体出水口2821c)，阀体进水口2821a与两个阀体2821出水口之间可以切换连通。喷洒水路281可以包括进水水路2811和两个出水水路(如图22所示的第一出水水路2812和第二出水水路2813)，进水水路2811分别与阀体进水口2821a和水箱236相连，水泵233可以串联在进水水路2811上，两个出水水路分别与两个阀体2821出水口相连， 其中一个出水水路上可以设有第一出水口，另一个出水水路上可以设有朝向地面开口的第二出水口(图中未示出)，由此可以提升表面清洁装置100的清洁效率。
为了方便区分和描述，将设有第一出水口的出水水路称为第一出水水路2812，将水控制阀282上与第一出水水路2812相连的阀体2821出水口称为第一阀体出水口2821b。将设有第二出水口的出水水路称为第二出水水路2813，将控制阀282上与第二出水水路2813相连的阀体2821出水口称为第二阀体出水口2821c。
具体而言，控制阀282可以调节水路系统28的出水方向。当需要朝向滚刷22喷水时，控制阀282可以使阀体进水口2821a与第一阀体出水口2821b之间相连通，水路系统28内的清洗液可以依次通过第一出水水路2812和第一出水口喷向滚刷22。当需要朝向地面喷水时，控制阀282可以使阀体进水口2821a与第二阀体出水口2821c之间相连通，水路系统28内的清洗液可以依次通过第二出水水路2813和第二出水口喷向地面。用户可以根据实际的使用需求选择第一出水口或第二出水口进行喷水。
例如，当地面上粘附有顽强的污渍时，滚刷22难以将污渍清除掉，可以控制控制阀282使阀体进水口2821a与第二阀体出水口2821c相连通，水路系统28内的清洗液可以集中喷向地面的污渍，清洗液可以对污渍进行浸泡和分解，由此可以使污渍与地面分离，滚刷22可以很容易地将污渍清理掉。
可选地，可以在第一出水口处设置第一喷嘴2812a，可以在第二出水口处设置第二喷嘴2813a，第一喷嘴2812a可以增大第一出水口的喷水面积，由此可以使滚刷22表面的水量分布更加均匀、清洁效果更好。第二喷嘴2813a可以增大第二出水口的喷水面积，由此可以提升表面清洁装置100的清洁效率。
在本申请的一些可选的实施例中，控制阀282可以为电磁三通阀，由此可以方便用户的实际操作。在图22所示的具体示例中，电磁三通阀具有两种工作模式，电磁三通阀上设有与其通信相连的控制器2826，控制器2826可以控制电磁三通阀的工作模式。当电磁三通阀处于第一工作模式时，控制器2826可以控制阀282体进水口和第一阀体出水口2821b之间连通，水箱236内的清洗液可以通过第一阀体出水口2821b排出。当电磁三通阀处于第二工作模式时，控制器2826可以控制阀282体进水口和第二阀体出水口2821c之间连通，水箱236内的清洗液可以通过第二阀体出水口2821c排出。当表面清洁装置100停止工作或处于干用工作模式时，控制水泵233停止工作。由此，通过上述设计，可以根据实际的使用需求灵活控制出水系统的出水量和出水位置，操作比较方便。
如图21所示，在本申请的一些实施例中，收纳容器112可以设在主机11的底壁上， 由此可以减小风机111的工作负荷。可以理解的是，将收纳容器112设在主机11的底壁上可以缩短收纳容器112与滚刷22之间的距离，从而可以减小风机111的负压损失，可以提升表面清洁装置100的吸尘效果。可选地，收纳容器112可以与壳体组成可拆卸连接，当表面清洁装置100长时间工作后，可以将收纳容器112从壳体上拆卸掉，从而可以方便将收纳容器112内的污物倒掉。
根据本申请的一些实施例，滚刷22可以进行拆卸，由此可以方便滚刷22的更换和维修。可以理解的是，当滚刷22长时间使用后，滚刷22的外表面会出现磨损而影响清洁效果，用户可以将旧的滚刷22拆卸掉并安装新的滚刷22。由此，可以使用户的实际使用更加方便。
根据本申请实施例的表面清洁装置100的控制方法，表面清洁装置100为如上所述的表面清洁装置100，控制方法包括如下步骤：
启动所述流体供应组件23，以向第一喷射口231和第二喷射口232中的一个供流体。
根据本申请实施例的表面清洁装置100的控制方法，通过设置控制阀282，可以控制第一喷射口231和第二喷射口232的工作状态，从而可以实现定点定向集中喷洒流体(例如水、水蒸气、或混合有洗涤剂的水)，以直接指向被清洁表面的污垢，易将污垢清洗干净，进而可以提升表面清洁装置100的清洁性能。
根据本申请的一些实施例，流体供应组件23可以包括控制电路234、水箱236和用于控制第一喷射口231和第二喷射口232通断的控制阀282，机身1和地刷壳体21中的至少一个与水箱236连接，控制阀282与控制电路234电连接。
表面清洁装置100的控制方法可以包括：
流体供应组件23可以控制表面清洁装置100在第一工作模式、第二工作模式和第三工作模式之间切换。
流体供应组件23可以控制第一喷射口231和第二喷射口232喷射流体以使表面清洁装置100进入第一工作模式。当表面清洁装置100处于第一工作模式时，第一喷射口231和第二喷射口232喷射流体，第一喷射口231可以对滚刷22进行喷射流体，以打湿滚刷22(例如打湿滚刷22上的软毛221或硬毛222)；第二喷射口232喷射的流体可以直接喷射到被清洁表面，可以用于软化、润湿污渍。
流体供应组件23可以控制第一喷射口231喷射流体以使表面清洁装置100进入第二工作模式。当表面清洁装置100处于第二工作模式时，第一喷射口231喷射流体，以用于打湿滚刷22。
流体供应组件23可以控制第二喷射口232喷射流体以使表面清洁装置100进入第 三工作模式。当所述表面清洁装置100处于第三工作模式时，第二喷射口232喷射流体，以用于软化、润湿污渍。
如图8-图10所示，在一些实施例中，可以启动流体供应组件23，以向第一喷射口231和第二喷射口232中的一个供流体。其中，表面清洁装置100包括第一工作模式、第二工作模式和第三工作模式，启动流体供应组件23。
当表面清洁装置100处于第一工作模式时，第一喷射口231和第二喷射口232喷射流体，第一喷射口231可以对滚刷22进行喷射流体，以打湿滚刷22(例如打湿滚刷22上的软毛221或硬毛222)；第二喷射口232喷射的流体可以直接喷射到被清洁表面，可以用于软化、润湿污渍。当表面清洁装置100处于第二工作模式时，第一喷射口231喷射流体，以用于打湿滚刷22。当所述表面清洁装置100处于第三工作模式时，第二喷射口232喷射流体，以用于软化、润湿污渍。
根据本申请实施例的表面清洁装置100的控制方法，通过设置控制阀282，可以控制第一喷射口231和第二喷射口232的工作状态，从而可以实现定点定向集中喷洒流体(例如水、水蒸气、或混合有洗涤剂的水)，以直接指向被清洁表面的污垢，易将污垢清洗干净，进而可以提升表面清洁装置100的清洁性能。
下面参考图1-图15详细描述根据本申请实施例的表面清洁装置100的地刷组件2。地刷组件2包括地刷壳体21和滚刷22。需要说明的是，表面清洁装置100可以为吸尘器或干湿两用吸尘器。
具体而言，地刷壳体21具有地刷腔室211，地刷腔室211内设有挡板213，滚刷22设于地刷腔室211内，挡板213的自由端与滚刷22接触。需要说明的是，当滚刷22转动时，滚刷22上刷毛的自由端可以摔打到挡板213上，使挡板213可以起到挡水、刮水的作用，从而可以将滚刷22上的液体或者其他杂物摔打下来，有利于使滚刷22保持清洁、干爽，进而可以提升地刷组件2的清洁性能。
根据本申请实施例的表面清洁装置100的地刷组件2，通过在地刷腔室211内设置挡板213，且使挡板213的自由端与滚刷22接触，当滚刷22转动时，滚刷22上刷毛可以甩打到挡板213上，从而可以将滚刷22上的液体或者其他杂物甩打下来，有利于使滚刷22保持清洁、干爽，进而可以提升地刷组件2的清洁性能。
如图7和图13所示，根据本申请的一些实施例，滚刷22可以包括软毛221和多束硬毛222，硬毛222可以刮、蹭被清洁表面，以将被清洁表面上的污渍与被清洁表面分离开，软毛221可以擦拭被清洁表面，以用于清除污渍，通过利用硬毛222和软毛221 的配合，可以将污渍充分清除，进而可以提升地刷组件2的清洁性能。
根据本申请的一些实施例，地刷组件2还可以包括流体供应组件23。这里的“流体供应组件23”可以指供应液体或气体的部件，例如，其可以为地刷组件2提供水、带有清洁剂的液体或者水蒸气等。流体供应组件23与地刷壳体21连接，流体供应组件23包括第一喷射口231和第二喷射口232，第一喷射口231以向滚刷22喷射流体，第二喷射口232以向被清洁表面喷射流体。
需要说明的是，当被清洗表面上的污渍难以清除时，可以使第一喷射口231或第二喷射口232对准污渍，并向污渍上喷射流体(例如水、水蒸气)，流体以及流体喷射时所带来的冲击力，可以对污渍进行清洗、冲刷、软化，当滚刷22经过污渍时，可以很容易的将污渍清洁干净。
另外，还值得注意的是，在设置第一喷射口231和第二喷射口232时，可以将第一喷射口231的喷射方向、第二喷射口232的喷射方向设置为不同的喷射方向，例如，第一喷射口231的喷射方向可以设置为朝向滚刷22喷射，用于打湿滚刷22，当滚刷22沾有流体(例如滚刷22为湿漉的状态)时，有利于利用滚刷22将被清洁表面的杂物、污渍清洁干净；再如，第二喷射口232的喷射方向可以设置为朝向被清洁表面，用于打湿被清洁表面，对污垢先进行预处理(例如打湿、软化、添加洗涤剂)，当滚刷22经过有污渍的被清洁的表面时，滚刷22可以将被流体软化、打湿的污垢带走，同时将被清洁表面擦干净。
如图11、图14以及图15所示，地刷壳体21具有回水口212，回水口212与地刷腔室211连通，第一喷射口231或第二喷射口232喷出的流体可以通过回水口212被回收，由此可以使得被清洁表面更干爽、整洁，避免液态流体残留在被清洁表面。如图15所示，在一些示例中，挡板213可以设置于靠近回水口212的位置处。进一步地，在滚刷22转动的方向上，回水口212位于挡板213的上游。需要说明的是，滚刷22沿着其滚动方向滚动时，滚刷22上的液态流体沿着该滚动方向撞击到挡板213上，液态流体经过挡板213的撞击朝向滚刷22滚动的反方向或反方向区域运动，从而可以飞入到回水口212内，进而可以实现对流体的回收。
在本申请的一些实施例中，第一喷射口231可以为多个，多个第一喷射口231沿滚刷22的长度方向间隔开，由此可以提升喷湿滚刷22的速度，提升滚刷22清洁的效率。在本申请的一些实施例中，第二喷射口232可以为多个，多个第二喷射口232沿滚刷22的长度方向间隔开，由此可以增大喷射面积，提升第二喷射口232的喷射效率，使其可以覆盖污渍。
在本申请一些实施例中，流体供应组件23可以包括水箱236或蒸汽发生器。需要说明的是，当流体供应组件23包括水箱236时，第一喷射口231和第二喷射口232可以喷射出水或者混合有洗涤剂的水，从而便于打湿滚刷22、清洗污渍；当流体供应组件23包括蒸汽发生器时，第一喷射口231和第二喷射口232可以喷射出水蒸气，从而便于打湿滚刷22、软化污渍。
如图14-图15所示，在本申请的一些实施例中，第一喷射口231位于滚刷22的一侧，回水口212位于滚刷22的另一侧。由此可以使从第一喷射口231喷出的液体与滚刷22充分接触，滚刷22上混合有杂质、污垢的液体可以通过远离第一喷射口231的回水口212回收，从而可以使滚刷22即保持一定的湿度、又可以使滚刷22保持干爽不滴水，进而可以优化第一喷射口231和回水口212的布局。例如，在一些实施例中，第一喷射口231位于滚刷22直径的一端，回水口212大致位于该直径的另一端。
如图11所示，在一些实施例中，挡板213呈长条状，且挡板213沿滚刷22的长度方向(也可以理解为轴线方向)延伸，由此可以简化挡板213的结构。进一步地，挡板213的长度与滚刷22的长度可以大体相同。在一些实施例中，挡板213可以为多个，多个挡板213沿滚刷22的长度方向(也可以理解为轴线方向)间隔开。在一些实施例中，挡板213可以为多个，多个挡板213沿滚刷22的周向方向间隔开。为了加强挡板213的结构强度，如图11所示，在一些实施例中，地刷壳体21内设有多个加强肋214，多个加强肋214沿挡板213的长度方向间隔开，加强肋214连接于挡板213和地刷腔室211的内壁之间。
下面参照图16-图20以一个具体的实施例详细描述本申请的表面清洁装置100的水路系统28。值得理解的是，下述描述仅是示例性描述，而不是对本申请的具体限制。

如图17-图18所示，控制阀282包括：阀体2821、阀芯2822、驱动件2823、多个密封件2824和第一弹性件2825。
其中，阀体2821内限定出活动空间，阀体2821的外周壁上设有一个阀体进水口2821a和两个阀体2821出水口。阀体进水口2821a位于两个阀体2821出水口的上方。阀芯2822沿上下方向可活动地设在活动空间内，阀芯2822内设有液体流道28221，阀芯2822的外周壁设有与液体流道28221连通的阀芯进水口2822a和阀芯出水口2822b， 阀芯进水口2822a位于阀芯出水口2822b的上方，在阀芯2822的长度方向上，阀芯进水口2822a的长度大于阀体进水口2821a的长度，以使阀芯进水口2822a始终与阀体进水口2821a连通。
驱动件2823设在阀芯2822的上端，驱动件2823包括：按键23231和第二弹性件28232，按键23231设在阀芯2822上端，按键23231部分伸入至阀芯2822的液体流道28221内并与液体流道28221的内周壁过盈配合，按键23231部分位于阀体2821外侧。第二弹性件28232分别与按键23231和阀体2821接触，按键23231被按压时第二弹性件28232被压缩，以驱动阀芯2822活动以使得阀芯出水口2822b与不同的阀体2821出水口切换连通。
阀芯2822的外周壁上沿阀芯2822的长度方向间隔设有多个固定槽28222缺口28223，每个固定槽28222内嵌设有密封件2824，密封件2824与固定槽28222的底壁和活动空间的内壁止抵。其中，位于阀芯进水口2822a的两侧、阀芯出水口2822b沿阀芯2822的两侧均分布有密封件2824。第一弹性件2825设在活动空间的底壁上且与阀芯2822接触以常驱动阀芯2822朝向阀芯进水口2822a的方向移动。
需要说明的是，如图19所示，当未按压按键23231时，阀芯出水口2822b与位于上方(如图19中所示的上下方向)的阀体2821出水口连通，水箱236内的液体经过水泵233抽入到阀体进水口2821a的位置处，并经过阀芯进水口2822a进入到液体流道28221内，随后可以通过阀芯出水口2822b和位于上方的阀体2821出水口流出，以向表面清洁装置100的清洁头喷洒液体。
如图20所示，当按压按键23231时，按键23231驱动阀芯2822向下运动，使阀芯出水口2822b与位于下方(如图20中所示的上下方向)的阀体2821出水口相对，并挤压第一弹性件2825和第二弹性件28232发生弹性形变。水箱236内的液体经过水泵233抽入到阀体进水口2821a的位置，并经过阀芯进水口2822a进入到液体流道28221内，随后通过阀芯出水口2822b和位于下方的阀体2821出水口流出，以向地面喷洒液体。当停止按压按键23231时，在第一弹性件2825和第二弹性件28232的弹性恢复力作用下，可以驱动阀芯2822复位至图19中所示的位置。
下面参考图21-图23以另一个具体实施例详细描述本申请的表面处理装置。值得理解的是，下面描述仅是示例性的，而不是对本申请的具体限制。
如图21-图22所示，根据本申请实施例的表面处理装置，包括：主机11、清洁部件2a、水路系统28和控制装置29。
如图21所示，主机11包括壳体、风机111和收纳容器112，风机111和收纳容器112分别设在壳体上。其中，风机111设在收纳容器112的上端并与收纳容器112相连通，收纳容器112设在壳体的底壁上。清洁部件2a包括风道件215和清洁头，清洁头包括可转动的滚刷22、用于驱动滚刷22转动的驱动器224和安装罩225，安装罩225外罩在滚刷22上，滚刷22的外周壁上设有多个间隔分布的凸起223。风道件215的上端与收纳容器112的底部相连，风道件215的下端与安装罩225相连。
水路系统28包括水箱236、水泵233、喷洒水路281和控制阀282。控制阀282包括阀体进水口2821a、第一阀体出水口2821b、第二阀体出水口2821c和控制器2826，控制器2826可以控制阀282体进水口与第一阀体出水口2821b和第二阀体出水口2821c之间切换连通。喷洒水路281包括进水水路2811、第一出水水路2812和第二出水水路2813。进水水路2811的上端与水箱236相连，进水水路2811的下端与阀体2821出进口相连，水泵233串联在进水水路2811上。第一出水水路2812的一端与第一阀体出水口2821b相连，第一出水水路2812的另一端设有第一出水口，在第一出水口处设有第一喷嘴2812a，第一喷嘴2812a朝向滚刷22喷水。第二出水水路2813的一端与第二阀体出水口2821c相连，第二出水水路2813的另一端设有第二出水口，在第二出水口处设有第二喷嘴2813a，第二喷嘴2813a朝向地面喷水。
如图21所示，控制装置29包括控制板291和操作装置292，操作装置292设在壳体的外周壁上。控制板291分别与驱动器224和水泵233相连，操作装置292上设有第一自清洁档位292a和第二自清洁档位292b。在表面清洁装置100运行且第一自清洁档位292a或第二自清洁档位292b被触发时，控制装置29可以控制水泵233停止运行设定时间后再控制滚刷22停止转动。其中，第一自清洁档位292a对应的水泵233的停止时间点和第二自清洁档位292b对应的停止时间点相同，第一自清洁档位292a对应的滚刷22的转速低于第二自清洁档位292b对应的滚刷22的转速。
具体而言，表面清洁装置100具有干用和湿用两种工作模式，当表面清洁装置100处于干用工作模式时，水路系统28停止工作，风机111进行旋转，由此可以使收纳容器112与安装罩225内的空气之间形成负压。驱动器224可以驱动滚刷22进行转动，滚刷22在转动时可以擦拭地板并将地面上的灰尘和碎屑等污物卷起，在负压的作用下，灰尘和污物可以沿着风道件215进入到收纳容器112内，从而可以起到清除污物的目的。
当表面清洁装置100处于湿用工作模式时，风机111和水泵233同时开启，水泵233将水箱236内的清洗液抽入到喷洒水路281内，喷洒水路281内的清洗液通过第一出水口喷向滚刷22，滚刷22在转动的过程中可以对地面进行擦拭。滚刷22在转动的过程 中可以将其表面的污物和水渍甩向四周。在负压的作用下，污物和水渍可以沿着风道件215进入到收纳容器112内。当地面上粘附有顽强的污渍时，滚刷22上的水难以将污渍清除掉，可以调节控制阀282的控制器2826使阀体进水口2821a与第二阀体出水口2821c相连通，水路系统28内的清洗液可以集中喷向地面，清洗液可以对污渍进行浸泡和分解，从而可以使污渍与地面分离，由此，滚刷22可以很容易地将污渍清理掉。
当表面清洁装置100快要将地面清扫干净时，可以将表面清洁装置100调节至自清洁模式。若滚刷22上的污水较少时，可以触发操作装置292上的第一自清洁档位292a，水泵233首先停止运行、滚刷22继续转动，水箱236停止向滚刷22供水。在离心力的作用下，滚刷22上的污水和污渍可以与滚刷22分离并在负压的作用下顺着风道件215进入到收纳容器112内。当水泵233停止设定的时间后，滚刷22上的污水和污渍已经清理干净，此时控制装置29控制滚刷22停止转动。若滚刷22上的水较多时，则可以触发操作装置292上的第二自清洁档位292b，此时滚刷22的转动速度较快，可以提升滚刷22的自清洁效率。
