具体实施方式
为使本申请的上述目的、特征和优点能够更加明显易懂，下面结合附图对本申请的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本申请内涵的情况下做类似改进，因此本申请不受下面公开的具体实施例的限制。
在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本申请的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
在本申请中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
在本申请中，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
需要说明的是，当元件被称为“固定于”或“设置于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“上”、“下”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
近几年来，随着人们生活水平的不断提高，汽车已经走进千家万户，成为家庭日常的代步工具，因此，汽车的清洁需求也日渐增大。目前常见的洗车方法有：洗车房内人力洗车、自动电脑洗车、家用洗车器洗车、蒸汽洗车。不管是洗车房内人力洗车还是自动电脑洗车都面临洗车场所距离车主居住地较远、需要排队等待和用水量大的问题，既浪费水资源，浪费时间，洗车费用又高。家用洗车器，需要至少一桶量的水，提大桶水楼上楼下搬运不方便，也给用户每次洗车添加了很多麻烦，造成困扰，不适合城市人群。也有用手动充气泵作为动力源的喷水式的家用洗车器，不仅有以上缺点，费时费力，而且使用很不方便。节水蒸汽洗车，设备价格高，体积大不便于携 带，需要热源能量大，目前采用燃气和大功率电热，带来不安全隐患。
相关技术中，便携式压力清洗设备应运而生，其一般是通过例如柱塞泵产生高压水流来冲洗物体表面。虽然，相对于前述的清洗方式，该便携式压力清洗设备一定程度减少了用水量。但是，目前的便携式压力清洗设备是将泵、电机、电池包和喷枪集成一体，为达到较佳的清洗效果，对水量和出水压力需求依然较高，需要选择功率大的泵和电机。且在清洗过程中，选择功率大的泵和电机，则意味着续航时间会降低，为解决该问题，通常会增大供电电池包的容量，而如此增加了机器的重量，用户握持较费力，人机交互的体验不佳。
此外，当在清洗例如汽车、厨卫和墙面时，不能有效的使用该便携式压力清洗设备。具体而言，例如在一些清洗场景下，需要多角度、多清洗面的清洗，前述的便携式压力清洗设备仍然不能有效地接近每个待清洗面，如车顶或禁止使用压力水流清洗的清洗面。又例如，在另一些清洗场景中，待清洗面需要用户握举该便携式压力清洗设备，并控制该便携式压力清洗设备多角度清洗，这也意味着用户需要克服压力水流的反冲力以及该便携式压力清洗设备的重力作用，操作体验感并不佳，且单一的压力水流清洁效果并不好，需要用户使用清洗布配合擦拭清洗，费时费力。在又一些清洗场景中，采用压力清洗设备的压力水流将污垢剥离后，污垢会随着水流向下流动，如此，造成原本并不脏或清洗过的表面会被污染，而需要二次清洁。此外，在城市中用户洗车的场地受限，水源难以保证，另外，洗车后的污水的清理也是困扰用户的一个难题。这样，便导致了传统的便携式压力清洗设备的作业方便性和清洗效果表现受限。
因此，有必要提供一种便携式清洗设备，能够打破传统的便携式压力清洗设备的应用场景的局限，实现多清洗面、多角度的“多维度”的复杂工况清洗，且对水量和水压的要求相较于传统的便携式清洗设备较低，具有较佳的清洗效果。同时，能够有效收集污水，避免“二次污染”的情况发生，提高了便携式清洗设备的作业方便性和清洗效果。
本申请实施例以用于车辆清洗的清洗设备为例，对本申请中的便携式清洗设备的结构进行说明，在其他实施例中，该便携式清洗设备还可以用以清洗门窗、墙壁、落地玻璃等其他目标物，因此，本实施例仅用以作为范例说明，并不会限制本申请的技术范围。
本申请实施例中，“多清洗面”可以理解为便携式清洗设备的清洁头20能够清洁水平面、坡面、竖直面等。在实现清洁不同清洗面的多工况下，便携式清洗设备的清洁头20将呈现如图1、图3、图5多种不同使用姿态。例如，请参考图9，若以水平面(地面)为参考平面，清洁头20的长度方向X相对于水平面的角度可以是任意的角度，即清洁头20长度方向X的两端在竖直方向Z(也即重力方向)上因为不同清洗面的坡度不同而高低不同。
“多角度”可以理解为便携式清洗设备在实际清洗时，具有使用者手握便携式清洗设备的手握端与地面101的距离和清洁头与地面101的距离呈现不同结果的多个工作位置。例如，使用者可以握住握持部12，清洁头20整体相对于握持部12在竖直方向Z上处于靠上位置(如图8所示)、靠下位置(如图1、图2所示)、或者清洁头与握持部12大致处于同一高度(如图5所示)等方式进行清洗，并且，上述三种使用方式可以结合地使用。
如参考图8，可将清洁头20整体相对于握持部12在竖直方向Z上抬高，同时清洁头20的长度方向X的一端(如图8中靠近图面内侧的一端)相对于清洁头20的另一端在竖直方向Z上抬高以使得清洁头20的长度方向X与水平面形成夹角。
如图9和图10所示，本申请提供一种便携式清洗设备，包括：清洁头20；流体回收机构，具有污液容器40和流体回收动力源，所述清洁头20清洗待清洁面产生的脏流体70能通过所述流体回收动力源被抽吸至所述污液容器40内；握持部12，供使用者操作握持所述便携式清洗设备进行清洁作业；所述便携式清洗设备至少具有：握持部12距离地面的高度大于清洁头20距离地面的高度的第一工作位置(如图2)、以及握持部12距离地面的高度小于所述清洁头20距离地面的高度的第二工作位置(如图8)；其中，所述污液容器40设有排气结构，所述排气结构包括调整所述污液容器40的内腔压力的排气口622，所述便携式清洗设备处于所述第一工作位置或所述第二工作位置，所述排气口622均被配置为外露于所述污液容器40内的脏流体的液面的上方。
本申请的便携式清洗设备，用于执行清洗工作。如图9所示，将清洁头20对应的一端定义为前端(远端)，例如，该便携式清洗设备的前端是指使用者在利用该便携式清洗设备进行清洗作业时，远离使用者的一端。相应地，将用户握持的握持部12定义为后端(近端)，例如，该便携式清洗设备的近端是指使用者在利用该便携式清洗设备进行清洗作业时，该便携式清洗设备靠近使用者的一端。可以理解，上述定义仅为了说明，并不能理解为对本申请的限定。
具体的，如图9所示，本申请的便携式清洗设备包括保持杆10，保持杆10在前端和后端之间大致沿纵向方向Y延伸，清洁头20布置在保持杆10的前端，保持杆10的后端为握持部12，握持部12用于使用者操作握持。在本实施例中，握持部12上布置有一个或多个操作元件14，用户可以通过操作元件14控制该便携式清洗设备处于工作状态或非工作状态，例如，可以通过操作元件14控制该便携式清洗设备所处模式。污液容器40用于收纳清洁头20清洗待清洁面产生的脏流体70。可以理解，在其他一些实施例中，握持部12并非必然处于保持杆10的后端，例如，可以设置于保持杆10靠近其后端的位置，在此不作限定。
保持杆10包括保持杆壳体(图未标)，保持杆壳体内受保护地布置有例如用于将清洁头20产生的脏流体70回收至污液容器40的流体回收动力源等功能部件，以及诸如回收管路等具有不同功能的管路。在本实施例中，污液容器40以可拆卸地方式连接于保持杆壳体，当然在另外的实施例中，污液容器40也可以一体成型于保持杆壳体上，例如，保持杆壳体为注塑件，在注塑成型的过程中形成该污液容器40，在此不作限定。
清洁头20可以固定于保持杆10的前端，当然，清洁头20也可以活动连接于保持杆10的前端，但考虑到连接清洁头20和污液容器40的管路的缠绕问题，较佳地，清洁头20应被限制在一定的活动范围内。例如，在本实施例中，清洁头20通过铰接件围绕一枢转轴线枢转连接于保持杆壳体的前端，以使清洁头20能够在预定范围内摆动，清洁头20围绕枢转轴线的可摆动性能够在难以触及到的位置处也实现更好的清洁可能性，即，在一定程度上该清洗设备可以相对于待清洁表面变换姿态，从而达到更佳的清洁效果。具体地，该枢转轴线相较于保持杆10的纵长轴线横向地布置，例如，在一些实施例中，该枢转轴线与保持杆10的纵长轴线相互垂直，在另一些实施例中，该枢转轴线也可与保持杆10的纵长轴线呈锐角设置，以适应多角度、多清洗面的“多维度”清洗工况。进一步地，保持杆壳体上还可设有用于将清洁头20锁定于保持杆壳体上的锁定装置，使清洁头20相对保持杆壳体不可转动。
本申请的流体回收机构，用于将清洁头20清洗待清洁面产生的脏流体70抽吸至污液容器40内，具体是通过流体回收动力源将脏流体70抽吸至污液容器40内。
在本申请中，该污液容器40设有排气结构，该排气结构包括能调整污液容器40的内腔压力 的排气口622，该便携式清洗设备处于第一工作位置或第二工作位置，该排气口622均被配置为外露于污液容器40内的脏流体的液面的上方。
本申请的便携式清洗设备，能够打破传统的便携式压力清洗设备的应用场景的局限，实现多角度的的复杂工况清洗，具有较佳的清洗效果。同时，能够有效收集污水，避免“二次污染”的情况发生，提高了便携式清洗设备的作业方便性和清洗效果。
根据本申请的一个实施方式，在排气结构的一个可行实施例中，如图10所示，排气口622位于污液容器40内，该排气结构还包括：位于污液容器40内的浮子62，排气口622设于浮子62上；与浮子62相连的排气管路66，该排气管路66的一端与污液容器40的外部连通，其另一端伸入污液容器40内与排气口622连通，该污液容器40内的气体能经由排气口622和排气管路66排出至污液容器40外。
具体的，浮子62上设有配重块64，该配重块64与排气口622相对设置，该浮子62的浮力大于或等于配重块64的重力。应当理解，在脏流体70不断输送至污液容器40内，浮子62会随着脏流体70的液面上浮，由于用户操作便携式清洗设备的姿态变化，脏流体70容易通过排气口622进入排气管路66而外溢，影响用户的体验感。而将配重块64与浮子62上的排气口622对置，无论该便携式清洗设备的工作位置如何变化，如图11所示，受配重块64的制约，浮子62上的排气口622始终保持向上，从而避免脏流体70进入排气口622而导致脏流体外溢。如此，使污液容器40内的气压能保持稳定，避免污液容器40内的气压过大使脏流体70回流，且避免大量脏流体70通过排气管路66外溢，提高了用户体验性和机器的安全性和可靠性。
在另外的实施例中，配合参阅图10所示，该排气管路66的一端沿浮子62的径向穿入浮子62并延伸至排气口622处，该配重块64设置于排气管路66上。
具体的，排气管路66的另一端沿浮子62的径向穿入浮子62并延伸至排气口622处，配重块64设置于排气管路66上，例如，在本实施例中，配重块64可以套接于排气管路66上。容易理解，浮子62的质量较轻，例如可以为塑料或其他纤维材料制成，配重块64的质量较重，例如通常为金属材料。而将材质不同的配重块64直接连接于浮子62上，连接可靠性不佳，因此，在具体实施中将排气管路66的一端穿入浮子62并延伸至排气口622处，一方面避免从排气口622进入浮子62内的少量脏流体进入排气管路66，另一方面，便于固定配重块64的位置，使排气口622与配重块64对置。
虽然不希望受到理论限制，发明人研发发现，浮子62受到配重块64的制约而使得排气口622向上，但是便携式清洗设备在多角度的切换中，排气管路66仍然可能受到脏流体的影响而摆动拉扯浮子62，造成排气口622浸没或靠近脏流体70的液面。
故针对此问题，排气管路66被构造为能基于污液容器40内收集污水容量的变化调整其与浮子62的位置角度，该排气管路66的邵氏硬度为30A～40A。本申请的排气管路66被弹性地构造，使得排气管路66伸入污液容器40的部分能够随浮子62的浮动而摆动，从而避免造成排气管路66“拉扯”浮子62，而造成的排气口622浸没在脏流体70的液面。
进一步研究发现，排气管路66的材料特性例如硬度、排气管路66的机械尺寸例如直径，均直接影响排气管路66能否随浮子62浮动而摆动，且同时还需要兼顾排气管路66的排气速率和排气流量。因此，发明人发现当排气管路66的直径大于或等于2毫米，该排气管路66的邵氏硬度为30A～40A时，则可以保证排气管路66随浮子62浮动而摆动，并不会造成排气管路66拉扯 浮子62而带动浮子62运动，如此，一方面能够避免排气口622浸没或靠近脏流体70的液面，另一方面保证排气速率和排气量以保持污液容器40内的气压保持稳定。优选的，该排气管路66的直径为3毫米。
在排气结构的另一可行实施例中，如图12所示，排气口622开设在污液容器40上，设有该排气口622的污液容器40能转动地/可位移地连接在便携式清洗设备上，以响应于便携式清洗设备在第一工作位置和第二工作位置的变化而调整排气口622的位置。
具体的，保持杆10上设有自适应接头16，污液容器40通过自适应接头16连接于保持杆10，使得污液容器40上的排气口622位于污液容器40内的脏流体的液面的上方。如此，在“多角度”的清洗中，防止脏流体70的回流和外泄。
其中，在本申请中，在所述便携式清洗设备在不同工作位置变化，原则上排气口始终外露于污液容器40内的脏流体70的液面的上方。当然，申请人需要强调，针对污液容器40在只有脏流体70盛满外溢的情形而出现的排气口622被脏流体70浸没、以及便携式清洗设备瞬时位置变化，而出现的排气口622仅一刹那的浸没，其余情况下，排气口622基本均外露于污液容器40内的脏流体70的液面的上方都应该被理解为本申请所覆盖。
根据本申请的一个实施方式，如图13所示，所述便携式清洗设备还包括供液机构，所述供液机构包括：能盛装清洁流体的流体容器30；重力单元342，设于所述流体容器30内，所述重力单元342上设有吸液孔；供液泵32，用以提供向所述清洁头20加载清洁流体的动力；供液电机(未标号)驱动供液泵32工作，供液管路344，连通所述吸液孔，所述供液泵32通过所述供液管路344将液体向所述清洁头20输送；其中，所述重力单元342的浮力小于所述重力单元342的重力。
具体的，如图14和图15所示，重力单元342包括重力浮球，该重力浮球上设有吸液孔(图未示)，重力浮球设置于流体容器30内，供液管路344的一端与重力单元342连接，其另一端与清洁头20连接，供液泵32通过管路连通重力单元342，用以提供向清洁头20加载清洁流体的流体动力，以湿润清洁头20，便于清洁头20清洁待清洁表面。
其中，重力单元342的浮力小于重力单元342的重力，如此，重力单元342始终在清洁流体的液面以下，从而在清洗设备处于多维度姿态下，仍然能够良好地向清洁头20供应清洁所需的清洁流体，以实现多清洗面、多角度的“多维度”清洗。
进一步地，该供液管路344弹性地构造，使得供液管路344伸入流体容器30的部分能够随重力单元342的浮动发生形变，从而使吸液孔保持于流体容器30内的清洁流体液面以下，实现不中断的供液。在本实施例中，供液管路344为硅胶软管。
本申请的供液机构，能够在便携式清洗设备处于多维度的作业中，不间断地向清洁头20供应清洁流体，提高了便携式清洗设备的使用便利性。另外，通过设置重力单元342，能够保证吸液孔始终位于流体容器30内的清洁流体的液面下方，有效保证清洁流体的顺利供应。
根据本申请的一个实施方式，如图16、图17和图21所示，所述清洁头20包括清洁头壳体22、绕一轴线可转动地连接于所述清洁头壳体22的清洁刷24以及设在所述清洁头壳体22内的去污单元28，所述去污单元28被配置为能作用在所述清洁刷24；所述便携式清洗设备还包括污液容纳腔222，所述污液容纳腔222设置在所述污液容器40的上游，用于作为第一收集区域收集由所述去污单元28从所述清洁刷24上去除的脏流体70。
本申请的流体回收动力源能将第一收集区域收集的脏流体回收至污液容器40中，其中污液容器40可以理解为本申请便携式清洗设备的第二收集区域。
具体的，请配合参阅图18所示，清洁头20包括清洁头壳体22和具有一旋转轴线的清洁刷24，清洁刷24围绕该旋转轴线可转动地连接于清洁头壳体22上，待清洁的表面在清洁过程中，该便携式清洗设备通过清洁刷24放置在有待清洁的表面上并且仅通过清洁刷24支撑在待清洁的表面上。操作者握持握持部12以操作该便携式清洗设备，其中，在正常工作时操作者是站立的，操作者可以调整便携式清洗设备相对待清洁的表面的姿态实现多角度、多清洗面的“多维度”清洁。
如图19和图20所示，清洁头壳体22包括收容腔室(图未标)和与收容腔室流体连通的开口(图未标)，清洁刷24定位于清洁头壳体22以绕旋转轴线作旋转运动，该开口的纵长延伸方向与所述旋转轴线平行，以使清洁刷24的部分穿过开口收容于收容腔室内。具体地，如图19所示，清洁头壳体22包括本体225和保持部226，收容腔室和开口设于本体225，保持部226从本体225纵长延伸的两端向远离开口的一侧延伸，清洁刷24横向地保持于本体225两端的保持部226之间，且部分收容于收容腔室内，以使清洁刷24的清洁表面具有外露于收容腔室的外露区域和收容于收容腔室内的隐藏区域。具体到一些实施例中，该开口的纵长长度大于清洁刷24的长度，该开口的宽度小于清洁刷24的直径，以使清洁刷24能够部分收容于收容腔室内。
在本实施例中，该清洁头20的收容腔室内还设有流体加载装置，该流体加载装置固定于清洁头壳体22，且被构造为能够至少向清洁刷24的长度方向上加载清洁流体。
具体地，该流体加载装置包括喷液管26，该喷液管26纵长地与清洁刷24相邻布置，且清洁刷24上以预设密度设有多个喷液孔262，如图18所示。较佳地，喷液管26的纵长延伸方向与清洁刷24的旋转轴线相平行，多个喷液孔262沿喷液管26的纵长方向间隔布设成一列。在清洁刷24转动过程中，喷液孔262向清洁刷24持续喷射清洁流体，从而使清洁刷24的圆周表面均被湿润，进而保证清洁效果。应当理解的是，喷液孔262的布置形式还可以为其他，例如，多个喷液孔262在喷液管26的圆周表面密集排布，在喷液管26的圆周表面密集排布是指在清洁刷24的纵长方向上布设有多个喷液孔262，在清洁刷24的圆周方向也布设有多个喷液孔262。作为一种具体的实施方式，多个喷液孔262在清洁刷24上阵列排布，即形成有多行喷液孔262和多列喷液孔262。
值得强调的是，由于喷液管26上密集布设有多个喷液孔262，单个喷液孔262的尺寸相较于现有技术中的喷液口或喷液缝隙的喷液面积较小，可以提供足够的喷液压力使清洁流体可以垂直地、均匀地喷射在清洁刷24上，满足清洁需求的前提下，节省了流体量。且在工作中，在喷液管26上不同位置的喷液孔262垂直喷液，可以使该清洗设备在不同工作位置下，清洁流体喷射到清洁刷24上的喷射区域足够大，从而保证清洁刷24被均匀湿润，实现多角度和多清洁面的“多维度”清洁。
还应当理解的是，喷液孔262的尺寸影响着清洁流体的喷液压力和喷液流量，由于便携式清洗设备的流体容器30容量和供液泵32的流量较小，为满足清洁效果下的喷液压力和喷液流量，则喷液孔262的尺寸、喷液流量应当满足一定的关系。虽然不希望受到理论限制，本申请的发明人研究发现，所述喷液孔262的直径为0.15毫米～0.5毫米，所述喷液孔262的流量为60毫升/分～90毫升/分，可以保证“多维度”清洁的同时，且具有较佳的清洗效果。
如图21和图22所示，清洁头壳体22内设有用于接纳脏流体的污液容纳腔222和连通污液容纳腔222的污液输出口224，该污液容纳腔222与前述的收容腔室连通，清洁刷24清洗待清洁面产生的脏流体70能够通过污液输出口224输送至污液容器40。具体地，污液容纳腔222具有与清洁刷24相邻的开口端220、与开口端220相对设置的封闭端221，以及连接开口端220和封闭端221的连接壁223。作为一种实施方式，污液输出口224可以设于封闭端221，作为另一种实施方式，污液输出口224也可以设于连接壁223上，在此不作限定。
清洁头20还包括用于刮取脏流体70的去污单元28，该去污单元28被配置为作用在清洁刷24，使清洁刷24携带的脏流体70(尤其是含有污物颗粒的水)脱落，并且向污液容纳腔222的开口端220输送，以将脏流体70由污液容纳腔222向污液容器40输送收集。具体地，去污单元28位于前述的收容腔室内并与清洁刷24和污液容纳腔222相邻设置，且布置于供液机构和污液容纳腔222之间，去污单元28包括一个或多个伸入到清洁刷24的包覆物(刷毛)内达到预设深度的构件，该构件被设置为朝向清洁刷24的圆周表面倒圆或倒棱地构造，从而能够将脏流体70导引至污液容纳腔222的开口端220。需要注意的是，该预设深度应当小于清洁刷24的包覆物的厚度。
进一步地，污液容纳腔222的开口端220的纵长延伸方向与清洁刷24的旋转轴线相平行，如此，有利于去污单元28将脏流体70导引至污液容纳腔222的开口端220。
根据本申请的一个实施方式，所述污液容纳腔222沿其长度方向的两端分别设有回收所述污液容纳腔222内脏流体的污液输出口224，所述清洁头20具有所述污液容纳腔222的一端相对其另一端在重力方向处于抬高位置的第一使用姿态，在所述第一使用姿态下，远离所述污液容纳腔222的抬高位置的另一端的所述污液输出口224被配置为与所述流体回收动力源相连通。
具体的，污液输出口224为第一污液输出口2241和第二污液输出口2242。流体回收机构能将承接在污液容纳腔222中的脏流体70通过第一污液输出口2241和/或第二污液输出口2242进行回收。优选的，第一污液输出口2241和第二污液输出口2242的数量均为一个。当然，第一污液输出口2241和第二污液输出口2242的数量也可以分别为多个。
在本实施例中，第一污液输出口2241和第二污液输出口2242的位置均被配置为偏离污液容纳腔222的中心线。具体的，第一污液输出口2241和第二污液输出口2242位于自污液容纳腔222长度的中心线向两端偏离预设距离设置，该预设距离配置为大于等于污液容纳腔222长度的1/4。其中，中心线可以理解为基本位于污液容纳腔222长度方向(X方向)的中部。中心线与清洁刷24的旋转轴线相垂直。可选的，第一污液输出口2241和第二污液输出口2242基本关于中心线对称。
进一步的，如图10、图23、图25和图39所示，污液容纳腔222内的脏流体70通过第一回流支路232和第二回流支路233回收至污液容器40。其中，第一回流支路232和第二回流支路233均包括伸入至污液容纳腔222进行脏流体吸收的进口端。
在一可行实施方式中，如图39所示，污液容纳腔222沿其长度方向的两端设有第一污液输出口2241和第二污液输出口2242，第一污液输出口2241和第二污液输出口2242配置为由第一回流支路232、第二回流支路233的进口端230形成。具体的，第一回流支路232、第二回流支路233的至少部分延伸入污液容纳腔222内，两个回流支路的进口端230固接在污液容纳腔222的相对两端。
可选的，在一种实施方式中，如图26和图27所示，第一污液输出口2241和第二污液输出口2242直接由污液容纳腔222的本身结构构造形成。具体的，污液容纳腔222包括收集清洁刷24产生脏流体的本体，第一污液输出口2241和第二污液输出口2242配置为贯穿污液容纳腔222两端的本体形成的通孔，流体回收机构连接通孔将脏流体70吸出。
如图1、图3和图5所示，所述便携式清洗设备具有所述污液容纳腔222的一端相对其另一端在重力方向处于抬高位置的第一使用姿态，及污液容纳腔222的两端的污液输出口224基本处于同一水平面上的第二使用姿态。在所述第一使用姿态，位于污液容纳腔222的抬高位置的一端的污液输出口224被配置为与流体回收动力源相连通。便携式清洗设备在第一使用姿态和第二使用姿态下均具备污液容纳腔222其中一端的污液输出口224被配置为供清洁刷24产生的脏流体流经。其中同一水平面可以理解为两端的污液输出口224与水平地面的距离相同。
如图23所示，在一可行的实施例中，该流体回收动力源包括能使脏流体70流经其并被抽吸至污液容器40内的排液泵52，该排液泵52为一个，该排液泵52的进液口与至少能与两端的所述污液输出口的一端相连通，所述排液泵52的出液口与所述污液容器40连通。
具体的，排液泵52的进液口借助管路与第一污液输出口2241和/或第二污液输出口2242连通，排液泵52的出液口借助管路与污液容器40连通。
在本实施例中，该排液泵52为蠕动泵或隔膜泵。可以理解，隔膜泵是利用隔膜作往复运动而改变隔膜泵内的腔体的容积，从而改变隔膜泵内的腔体内的水压，且具有单向性，可防止脏流体回流。例如，该隔膜泵包括电机和偏心轮，电机驱动偏心轮转动，一轴承的一端抵靠在偏心轮的边缘，轴承的另一端抵靠在隔膜的一侧面，这样，便使偏心轮通过轴承带动隔膜作往复运动，进而改变隔膜界定出的腔体的容积和水压。其中，隔膜泵的隔膜的材质可以为氯丁橡胶、氟橡胶或丁晴橡胶等材质，从而也具有较佳的抗腐蚀性能，且隔膜泵相较于传统的柱塞泵，结构较为简单、体积较小，还起到提高便携式清洗设备的便携性的功效。
如图24和图25所示，在另一可行的实施例中，所述流体回收动力源包括能使脏流体70通过回收管路抽吸至所述污液容器40内的一个气泵544或一个风机542，所述回收管路至少能与两端所述污液输出口中得一端相连通。
具体的，该流体回收动力源为负压产生装置，该负压产生装置是通过抽吸污液容器40内的气体，以使污液容器40内产生负压环境，从而使脏流体70能够被抽吸至污液容器40外。在该些实施例中，沿脏流体的流动方向，负压产生装置位于污液容器40的下游，脏流体70不会流经负压产生装置，而是直接进入污液容器40。
应当理解的是，由于上述的实施例中，从污液输出口224输出的脏流体70不需要经过前述的气泵544或风机542，因此，气泵544或风机542的主要考量因素为能够产生真空负压环境为主，而不要求具有较佳的抗腐蚀性能，作为一种可选地实施方式，该气泵544可以为隔膜泵、柱塞泵、蠕动泵或电磁泵。
其中为了防止有脏流体进入隔膜泵，而导致隔膜泵失效。可以在隔膜泵的上游增加过滤装置(未图示)，具体的，过滤装置设置在污液容器40上。避免长时间使用后细小沙粒等杂质对隔膜泵的腐蚀。
可以理解，由于清洗设备的多角度使用变化，脏流体70同样容易通过管路进入负压产生装置，造成负压产生装置停止工作或脏流体70外溢，影响用户体验。例如，在本实施例中，负压 产生装置为风机542或气泵544，而脏流体70一旦大量进入气泵544或风机542，则容易造成气泵544或风机542损坏，或者造成脏流体70外溢。
因此，在该实施例中，设有与图10和图11所示的排气结构类似的抽气单元，该抽气单元包括抽气浮球546和配重块548，抽气浮球546设置于污液容器40内，抽气浮球546设有风道口547，配重块548与风道口547相对设置。气泵544或风机542通过负压抽吸管路549与抽气浮球546连接，用以借助于风道口547抽吸污液容器40内的气体，从而提供使脏流体通过管路抽吸至污液容器40的负压条件。该抽气单元的有益效果与图10和图11所示的排气结构相同，在此不再赘述。
在图25的实施例中，风机542包括风腔540和位于风腔540内的风扇，负压抽吸管路549的一端与风腔540连通，另一端与抽气浮球546连通。与之前的实施例相似，利用风扇的旋转产生抽吸力可以将污液容器40内的气体抽吸排出而产生负压环境。该实施例中与之前的实施例不同之处在于：流体回收动力源为风机542，相同之处在此不作赘述。
本申请的发明人研究发现，在“多维度”的清洗过程中，清洗设备的姿态不断切换，致使第一污液输出口2241在重力方向位于污液容纳腔222的抬高位置的一端，而脏流体70在重力的作用下均流向污液容纳腔222的压低位置的另一端的(处于下方)的第二污液输出口2242，当流体回收动力源只有一个排液泵52分别对两端的污液输出口抽吸时，位于污液容纳腔222的抬高位置的一端的污液输出口的空气抽吸相较位于下方压低位置的污液输出口的脏流体抽吸容易，无法形成气压差，导致位于下方的污液输出口的脏流体抽吸困难。
是故，根据本申请的一个实施方式，在所述污液容纳腔222沿清洁头20的长度方向的两端分别设有一个污液输出口的实施例中，该便携式清洗设备还包括封堵机构29，所述封堵机构29能关闭沿重力方向位于所述污液容纳腔222的抬高位置的一端的所述污液输出口与流体回收动力源的通路，并打开沿重力方向位于所述污液容纳腔222压低位置的另一端的所述污液输出口与流体回收动力源的通路。
在本实施方式中，如前所述，便携式清洗设备具有第一使用姿态和第二使用姿态；其中，在所述便携式清洗设备处于第一使用姿态下，两端的所述污液输出口在重力方向上彼此错开，在重力方向上位于抬高位置的所述污液输出口被所述封堵机构29封堵，在重力方向上位于压低位置的所述污液输出口被所述封堵机构29打开。如此，能够有效地解决两端污液输出口无法形成气压差，导致压低位置(下方)的污液输出口的脏流体抽吸困难的问题。
在所述便携式清洗设备处于第二使用姿态的状态下，位于污液容纳腔222两端的所述污液输出口基本位于同一水平面上，两端的污液输出口均完全打开；具体的，封堵机构29与清洁头20的污液输出口对应。在便携式清洗设备处于第二使用姿态的状态下，两端的污液输出口位于同一水平面上，两端的污液输出口均完全打开，即与污液输出口一一对应的两个封堵机构29均不动作。
如图26和图27所示，在封堵机构29的一个可行实施例中，其包括：封堵件292，沿所述污液容纳腔222的长度方向滑动连接于所述清洁头20，用于封堵对应的所述污液输出口；以及致动部294，沿所述污液容纳腔222的长度方向可移动地连接于所述清洁头20，且被构造为响应于所述便携式清洗设备的不同姿态而发生运动；其中，所述致动部294被配置为在移动过程中能够作用于所述封堵件292，以带动所述封堵件292沿预设方向移动，从而使所述封堵件292能够至少 部分地封堵对应的所述污液输出口224。
具体的，该封堵机构29还包括弹性件296；该弹性件296的一端连接于清洁头壳体22，其另一端连接于封堵件292，该弹性件296用于提供使封堵件292具有沿与该预设方向相反的方向移动趋势的弹力。
在本实施例中，封堵件292沿污液容纳腔222的纵长延伸方向滑动连接于污液容纳腔222的封闭端221，污液容纳腔222的连接壁223设有滑槽，封堵件292的一端设有连接部293，连接部293经由滑槽伸出并与弹性件296连接。如此，一方面滑槽和连接部293可以对封堵件292的移动进行限位，另一方面便于与弹性件296连接。
污液容纳腔222的外侧设有用于容置致动部294和弹性件296的安装腔，致动部294具体可以为重力球，其沿污液容纳腔222的纵长延伸方向可滚动地设置于安装腔内，封堵件292的另一端通过拉绳291与致动部294连接。其中，拉绳291可以通过定位柱295进行导向，弹性件296可以为弹簧，弹簧的一端连接于安装腔的内壁，另一端连接于封堵件292的连接部293。当清洗设备处于第一使用姿态，在重力方向位于下方的(压低位置)重力球在重力作用下向下移动，拉绳291处于松弛状态，在弹性件296的作用下封堵件292移动使污液输出口至少部分地打开。在重力方向位于上方的(抬高位置)重力球在重力作用下向下移动，拉绳291处于张紧状态，对应的弹簧被拉伸，封堵件292至少部分地封堵对应的污液输出口。
当便携式清洗设备处于第二使用姿态，封堵件292在弹性件296的作用下保持与污液输出口完全错开；该便携式清洗设备处于第一使用姿态，致动部294在重力作用下沿预设方向相反的方向移动，拉绳291拉动封堵件292以使封堵件292能够克服弹性件296的弹力而沿预设方向移动，从而至少部分地封堵污液输出口。
在封堵机构的另一个可行实施例中，如图28所示，其包括三通管路和封堵器56，如前所述，污液容纳腔222沿所述清洁头20的长度方向的两端均分别设有第一污液输出口2241和第二污液输出口2242；三通管路具有分别与第一污液输出口2241和第二污液输出口2242连通的第一回流支路232和第二回流支路233、以及与第一回流支路232和第二回流支路233连通的汇聚支路234，汇聚支路234与污液容器40相连通；封堵器56设置于三通管路内，且被配置为响应于便携式清洗设备的姿态保持静止以连通三通管路的所有支路或者择一地封闭第一回流支路232和第二回流支路233。
具体的，该便携式清洗设备处于第二使用姿态，两个回流支路均与汇聚支路234连通，该便携式清洗设备处于第一使用姿态，污液容纳腔222两端的第一污液输出口2241和第二污液输出口2242在重力方向上彼此错开，在重力方向上位于上方的(抬高位置)污液输出口对应的回流支路借助封堵器56封堵，在重力方向上位于下方的(压低位置)污液输出口对应的回流支路打开。封堵器56可以根据便携式清洗设备的姿态而选择保持所有回流支路连通汇聚支路234，或者择一地选择一个回流支路与汇聚支路234连通。
进一步的，该便携式清洗设备还包括角度传感器80和控制器90；该封堵器56与控制器90通信连接，该控制器90被配置为根据角度传感器80的检测结果确定便携式清洗设备的姿态，并控制封堵器56保持静止以连通三通管路的所有支路或者择一地封闭第一回流支路232和第二回流支路233。如此，同样能够有效地解决第一污液输出口2241和第二污液输出口2242无法形成气压差，导致下方污液输出口的脏流体抽吸困难的问题。
如图29所示，在另外的实施例中，该封堵器56包括两个阀门，两个阀门一一对应地安装于第一回流支路232和第二回流支路233中；其中，两个阀门在第一回流支路232和第二回流支路233之间往复运动，以择一地封闭第一回流支路232和第二回流支路233。
具体的，污液容器40设有两个污液进口，每一污液输出口借助管路与一端的污液进口连通，该便携式清洗设备还包括电磁阀58，电磁阀58被配置为响应于便携式清洗设备的姿态保持打开每一污液进口或者择一地关闭一个污液进口。
在本实施例中，该便携式清洗设备处于第二使用姿态，电磁阀58不动作，每一污液进口均打开；该便携式清洗设备处于第一使用姿态，在重力方向上位于上方的(处于污液容纳腔222抬高位置一端的)污液输出口对应的污液进口被电磁阀58关闭，在重力方向上位于下方的(处于污液容纳腔222压低位置一端的)污液输出口对应的污液进口打开。进一步地，该便携式清洗设备还包括角度传感器80，角度传感器80与电磁阀58通信连接，电磁阀58被配置为根据角度传感器80的检测结果确定便携式清洗设备的姿态，并控制保持打开每一污液进口或者择一地关闭一个污液进口。
如此，使不同的污液进口在便携式清洗设备处于不同姿态下适应性地打开或封闭，有利于保证污液容器40内的负压环境，从而提高脏流体抽吸效率。
在封堵机构29的再一个可行实施例中，封堵机构29包括三通阀27，三通阀27包括分别与第一回流支路232和第二回流支路连接得两个进管端口272、以及和所述汇聚支路234连接得一个出管端口273，所述三通阀具有内腔2711，两个所述进管端口272和所述出管端口273分别与所述内腔2711相连通；所述内腔2711中设有：两个活动件274，分别用于封堵两个所述进管端口272与所述第一回流支路232和所述第二回流支路233之间的通路；至少一个驱动单元275，置于两个所述活动件274之间；其中，在重力的作用下，所述驱动单元275能驱动所述活动件274以封堵对应的所述进管端口272。
具体的，三通阀27具有阀体271，阀体271的两个进管端口272分别与第一污液输出口2241和第二污液输出口2242连通，阀体271具有内腔2711，两个进管端口272和出管端口273分别与内腔2711相连通。
在一种实施方式中，如图38所示，活动件274为一个，在重力作用下，一个活动件274在阀体271的内腔内运动，以封堵一个进管端口272，打开另一个进管端口272。
可选的，在另一种实施方式中，活动件274可以为两个，分别用于封堵两个进管端口272；至少一个驱动单元275，置于两个活动件274之间；其中，在重力的作用下，驱动单元275能驱动两个活动件274以封堵对应的进管端口272。
具体的，在一可行的实施例中，封堵机构29包括至少一个驱动单元，至少一个驱动单元置于两个活动件之间。如图30至图33所示，具体的，该驱动单元275为两个，位于两个活动件274之间；在其中一活动件274封堵相对应的进管端口272的状态下，另一活动件274与相对应的另一进管端口272分离，出管端口273与另一进管端口272连通。
在本实施例中，活动件274可为不锈钢球，驱动单元275也可为不锈钢球，且驱动单元275的外径大于活动件274的外径，以利驱动活动件274移动。
当清洗设备在清洁头右端处于压低位置，左端处于抬高位置工作时，三通阀27的内部状态如图31所示，当流体回收机构打开时，三通阀27内部的四个不锈钢球会沿坡道下滑，对阀体271 的进管端口272的压力为F＝2×(M1+M2)g×sinθ，其中，90°≥θ≥0°，M1为活动件274的质量，M2为驱动单元275的质量，单位均为克。此时右侧最底部的钢球对进管端口272形成了密封，污液容纳腔222中的水由另一进管端口272进入，并从出管端口273流出，进入污液容器40。
当清洗设备的清洁头在竖直状态下进行洗车工作时，三通阀27的内部状态如图32所示，当流体回收机构打开时，三通阀27内部的四颗不锈钢球会沿坡道下滑，右侧最底部钢球对进管端口272形成了密封，对进管端口272的压力为F＝2×(M1+M2)g，此时污液容纳腔222中的污水由另一进管端口272进入，并从出管端口273流出，进入污液容器40。
当清洗设备在水平状态下洗车工作时，三通阀27的内部钢球状态如图33所示，当流体回收机构打开时，三通阀27内部的四颗不锈钢球对两个进管端口272、出管端口273形成不了密封，此时污液容纳腔222中的脏流体70由两个进管端口272进入，并从出管端口273流出，进入污液容器40。
在另一可行的实施方案中，如图34所示，驱动单元275为一个，位于两个活动件274之间；阀体271连接有摆动杆276，摆动杆276与驱动单元275相连；在摆动杆276的摆动作用下，摆动杆276能带动驱动单元275朝向其中一活动件274运动以封堵相对应的进管端口272，另一活动件274远离进管端口272。
本实施例利用摆动杆276外部连接的摆锤277在重力作用下带动摆动杆276左右摇动，进而带动连接在其下部的驱动单元275往相反的方向运动，以推动活动件274朝向进管端口272的圆弧面移动，基于与圆弧锥面相切密封原理，随着清洗时角度的切换，阀体271内部的活动件274密封的进管端口272不一样，实现了抽取两处污水的切换，切换快速高、故障率低、成本低、用料简单且工作效率高。
本实施例的三通阀27，依靠阀体271内的摆动杆276的自由摆动实现三通阀27的开启与闭合，步骤在于：内部钢球由于摆动杆276下方钢球的挤压，两侧中的其中一侧小钢球与锥形管道内壁形成密封阀门，实现进管端口272的开启与闭合切换，此时摆杆下方的小钢球对管口进行封堵，同时另外两个通道口连通，液体通过这两个通道口流动，实现液体的输送。
进一步的，该阀体271的内腔壁面形成有供活动件274朝向对应的进管端口272移动的渐缩部2712。渐缩部2712的设置，利于活动件274朝向对应的进管端口272位移。
如前所述污液容纳腔222沿所述清洁头20的长度方向的两端分别设有第一污液输出口2241和第二污液输出口2242。如图35所示，提供了本申请的再一实施方式的便携式清洗设备，流体回收动力源包括两个排液泵52；两个所述排液泵52的进液口分别与两端的污液输出口224连通，两个所述排液泵52的出液口分别与污液容器40连通。
具体的，各排液泵52的进液口分别通过一个管路直接连通各端的污液输出口，也即，两个排液泵52分别通过两个管路直接连通第一污液输出口2241和第二污液输出口2242。在该实施例中，与上述图23实施例中采用的排液泵52种类相同，本实施例中的排液泵52为蠕动泵或隔膜泵。
在一变形的实施方式中，如图36所示，污液容纳腔222沿清洁头20的轴向的两端分别设有第一污液输出口2241和第二污液输出口2242，所述污液容器40包括彼此独立且互不连通的第一腔室42和第二腔室44，两个所述污液输出口224分别通过第一流体回收管路和第二流体回收管 路与所述第一腔室42和所述第二腔室44连通；所述流体回收动力源包括两个气泵544或风机，两个所述气泵544或所述风机的进气口分别经由一负压抽吸管路与所述第一腔室42和所述第二腔室44连通。
在该实施方式中，虽然不存在上方的污液输出口的空气抽吸相较下方污液输出口的脏流体抽吸容易导致下方污液输出口的脏流体抽吸困难的问题，但是，本申请的发明人研究发现，若位于上方的污液输出口不断抽吸空气，则会影响污液容器40内的负压环境，造成位于下方的污液输出口的脏流体抽吸效率无法进一步提高。
具体的，流体回收动力源包括两个抽气浮球和两个配重块。具体而言，两个排气浮球分别为第一抽气浮球5462、第二抽气浮球5464，两个配重块分别为第一配重块5482和第二配重块5484，第一抽气浮球5462设置于第一腔室42，第二抽气浮球5464设置于第二腔室44，第一配重块5482与第一抽气浮球5462的风道口547对置，第二配重块5484与第二抽气浮球5464的风道口547对置。每一气泵544具有进气端和与外界连通的出气端，一个气泵544的进气端连通第一抽气浮球5462，另一个气泵544的进气端连通第二抽气浮球5464。如此，两个污液输出口224对应的腔室的脏流体抽吸互不影响，避免一个污液输出口抽吸空气影响负压环境。
如图37所示，在本申请中，该污液容纳腔222具有承接脏流体70的开口端、以及与开口端220相对设置的封闭端221，所述封闭端221具有第一导流面126和第二导流面127；所述第一导流面126和第二导流面127相连的一侧边与开口端220之间的距离小于第一导流面126和第二导流面127相远离的一侧边与开口端220之间的距离。
为进一步促进脏流体流向污液输出口而排出，一些实施例中，污液容纳腔222的封闭端221具有相向的一边彼此连接的第一导流面126和第二导流面127，第一导流面126和第二导流面127彼此相连的一边相较于两者彼此远离的一边更靠近开口端220，也即，污液容纳腔222的封闭端221“中间高”而“两边低”，两个污液输出口224用于分别输出第一导流面126和第二导流面127引流的脏流体。
具体地，两个污液输出口224分别设于第一导流面126和第二导流面127，且位于靠近第一导流面126和第二导流面127彼此远离的一边的位置；或者两个污液输出口224设于连接壁223的同一侧，且位于连接壁223靠近第一导流面126和第二导流面127彼此远离的一边的位置。如此，在“多维度”的清洗过程中，该清洗设备在不同姿态中切换，两个污液输出口224位于第一导流面126和第二导流面127的导流下游，有利于脏流体在便携式清洗设备处于不同姿态下的流体回收。
进一步的，所述污液容器40内的气体能经由负压排气管路与污液容纳腔222连通，该负压排气管路连接污液容纳腔222的连接处位于第一导流面126和第二导流面127的交界处。
具体的，前述的排气管路66远离浮子62的一端连通污液容纳腔222，且排气管路66远离浮子62的一端连接污液容纳腔222的连接处位于第一导流面126和第二导流面127的交界处。具体而言，排气管路66与污液容纳腔222的连接处位于污液容纳腔222的封闭端221的中间位置，如此，一方面，脏流体70进入污液容纳腔222内，受到重力作用和两个导流面的导流而朝向污液输出口224流动，不易进入排气管路66。另一方面，排气管路66在排气中会夹杂少量脏流体，而通过排气管路66可以把这少量脏流体从新输出至污液容纳腔222内进行“二次回收”，提高了脏流体的回收效率，又不会造成脏流体的外泄。再一方面，排气管路66排气过程中，气 流会将进入污液容纳腔222中的脏流体向两边扰流，如此进一步地提高了脏流体的回收效率，可谓一举三得。
本申请的提供便携式清洗设备在多角度下清洁工作，具体的，在握持部12距离地面的高度大于清洁头20距离地面高度的第一工作位置和握持部12距离地面的高度小于所述清洁头20距离地面高度的第二工作位置，且污液容器40未集满的状态下，脏流体70能保持在污液容器40内。且与流体回收动力源电连接的电机均能处于电连通状态。
进一步的，在便携式清洗设备处于第一工作位置或第二工作位置，污液容器40内的脏流体的容积大于或等于污液容器的40容积的1/4，且小于污液容器40的容积时，盛装在污液容器40内的脏流体70均能保持在所述污液容器40内。在本实施方式中，污液容器40的容积小于或等于700ml，优选的，污液容器40的容积小于等于500ml。
该污液容器40未集满是指：该污液容器40内的脏流体70的容积小于污液容器40的容积。
本申请的便携式清洗设备，在使用时，能够确保清洁头20上的脏流体70快速流入污液容器40内，且在污液容器40未集满的状态下，始终保持脏流体70不外漏，清洗设备能够正常工作，有效提高了本申请的便携式清洗设备的使用体验。
在本实施例中，该便携式清洗设备包括电池包50，电池包50用于为流体回收机构和供液机构提供电力，该电池包50可以为直流电源，具体可以为可充电的电池包，电池包以可拆卸地方式安装在保持杆10上。
具体地，保持杆10上设有供电池包结合的一个或者多个电池包安装部，该电池包安装部可以靠近握持部12设置，电池包的数量与电池包安装部的数量相匹配。应当理解的是，电池包安装部应靠近握持部12设置，可以实现重量单元尽可能的距离握持部12最近，减少使用者工作的疲劳度。
进一步的，前述的电池包至少能为两种不同种类的直流工具供电，例如可以通用于具有吹功能的电动工具、打草机、割草机、链锯、修枝机、角磨、电锤、电钻等电动工具。如此，使用者可以仅购买具有吹功能的电动工具的裸机，并通过利用已有的其它电动工具上的电池包来为具有吹功能的电动工具进行供电，实现多工具的能源共享，一方面，利于电池包平台的通用；另一方面，也为使用者节省了购买成本。
在本实施例中，电池包可采用卡扣方式或者插拔方式固定于电池包安装部上，例如，电池包包括于其两侧设有滑轨部(未标号)、于其上侧设有的卡扣部及若干电极连接片(未图示)。其中滑轨部可与电池包安装部配接实现电池包在径向上被限位，卡扣部与壳体卡扣连接，实现电池包在轴向上被限位，从而将电池包稳定的连接在电池包安装部上。
另一些实施例中，电池包还可以为直插式电池，也可以为其他能够供便携式清洗设备正常工作的电池，在此不作限定。当然，该便携式清洗设备还可以配备与车载电源或者其他供电设备连接的接头，在未使用时，该接头可以收容于保持杆壳体内，而在使用时，接头可以从保持杆壳体内取出。
以上所述的具体实施例，对本申请的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本申请的具体实施例而已，并不用于限定本申请的保护范围，凡在本申请的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
