Description

电动洗车器 说明书
技术领域
[0001] 本发明涉及汽车清洗设备技术领域，特别涉及一种便携式电动洗车器。
背景技术
[0002] 当前市面上的便携式电动洗车器，多是采用硬质敞口水箱，具备可绕车喷水一周的数米长水管，使用时，从汽车点烟器接电，水箱放置不动，水枪随人绕车喷水。例如申请号：201120254219.6的'圆桶形手提式电动洗车器'。
[0003] 这种洗车器有以下缺点：
1.体积大便携性差。2.取水靠手提，费力，尤其对女人而言。3.容积小，容积做大则便携性更差，难以放入某些小车的后备箱。4.必须将水桶放置在水龙头下面接水，取水麻烦，对水源挑剔，例如无法从加油站公厕的洗手台直接取水，需要用瓢舀水。5.由于水管冗长且使用时又在地面拖动磨损，沾上水和污渍，使用后收纳比较费事。6.带有灵活脚轮的洗车器放置在车辆后备箱中时，容易晃动造成异响给行车带来干扰。本发明旨在解决这些难题，同时还要解决下述问题。
[0004] 一、基于节能环保的诉求，政府号召大家不要用自来水洗车，倡导用雨后积水，池塘河流水等非饮用水洗车。然而这种号召却得不到响应，其主要原因是：上述非饮用水洁净度不高，水中的细小杂质容易堵塞洗车器的滤网产生故障，而经常清洁和替换滤网又增加了时间和经济成本。二、由于取水累人又不方便，人们往往偷懒在水源处就地洗车，使得洗车后的污水污染了水源。
发明内容
[0005] 本发明基于使洗车器随人绕车移动这个出发点展开设计，在洗车器外箱安装有脚轮助其移动，使用长度最短能绕车半周的电线，这样便于配合短的水管以利收纳。本发明的新颖之处在于：在水路上加入了一个手动换向水阀，换向水阀使洗车器使用软体水囊成为可能。它可以改变水流的方向，让水泵既能给水囊充水，也能从水囊里抽水以喷洒洗车。
[0006] 传统的水囊无法做到如此全封闭工作，它们都具有一个可开闭的口盖用以方便注水，为便于在注水时拎起水囊，通常还设计有利于手触的提手类装置。
[0007] 如附图1所示，本电动洗车器，主要由软体水囊（1）、换向阀（2）、箱体（3）和盖板（4）、电动水泵、水枪、出水管（5）组成；软体水囊（1）、出水管（5）、水泵的进出水口均连接到换向阀（2），换向阀（2）的切换，可以令水经过出水管（5）充入水囊或由水囊中喷出；软体水囊（1）可折叠，工作时全密封，水空后可收纳入箱体（3）；盖板（4）可盖在箱体（3）上，盖板（4）下面安装有脚轮，并且盖板（4）可以取下垫于箱体（3）的底部固定以移动承载箱体（3），洗车喷洒时洗车器随人移动。为了更加简洁便利设计为：出水管（5）的长度不足以绕车半周，出水管（5）承受人的拉力牵引洗车器随人移动。
[0008] 附图1中的带轮外箱有4个脚轮安装于盖板下面，盖板垫在外箱底部构成小车，手握水枪绕车喷洒时带轮外箱随人绕车移动。水泵和换向阀都被安装在箱体（3）中，收纳时盖板（4）盖在箱体（3）上，使脚轮收纳入箱体（3），还能把水枪和出水管等物件纳入箱体（3）内，收纳后变得像一个手提箱。为了抽水时不至于把水囊撑破：水泵带压力开关，此开关可以根据水压控制水泵电路的开闭，此开关压力设置为小于水囊被满水撑破时的水压。
[0009] 上述基础方案中，洗车器通过一根电线连接汽车点烟器插座给洗车器供电，该电线的长度与出水管（5）的长度之和，至少能够绕车半周，该电线通过收线盘（6）收卷。当然还可以在洗车器上直接安装蓄电池充当电源，或者点烟器供电方式与蓄电池供电方式两者兼备。此方案基于以下原因和需求，还可以进一步的完善获得更好的效果，下面详述。
[0010] 一、串并联增强型水泵，
原因：往水囊注水时需要流量大否则等待时间长，而洗车喷洒时需要水压大以增强冲刷能力，而这两个需求却是矛盾的，流量大的水泵洗车太耗费水，而压力大的水泵其流量却不一定大。
[0011] 措施：给洗车器配备2个或者2个以上的水泵（数量最好是偶数个）；把其进出水口都连接到另一个换向阀，换向阀的切换使水泵并联或者串联。让这个换向阀的开关与附图1里的换向阀联动，使注水时水泵并联，而洗车喷洒时水泵串联。
[0012] 如附图4所示，在基础方案基础上再增多一个电动水泵，并且再增多一个换向阀（203），两个水泵的进出水口都连接到换向阀（203），换向阀（203）的切换使洗车器注水时双泵并联喷洒时双泵串联，此双泵与换向阀（203）构成的整体视为一个增强电动水泵，其进出水口与另一个换向阀连接，增强型的总体水路如附图5。
[0013] 效果：水泵并联可以增大流量满足注水需求，而水泵串联可以增大水压满足冲刷需求。
[0014] 二、对开门扶持水囊，
原因：为了让洗车器体积小巧便携，比如为了便于塞进车内座椅下不占用空间，希望把外箱的高度设计的越低矮越好。为了盛装更多水，希望水囊容积越大越好。但是这两种需求就矛盾了，因为水囊是软的，水囊越大就越需要更高的外箱侧壁来扶持撑住它，否则水囊会塌下来甚至掉到地上。
[0015] 措施：给外箱的敞口一面内安装两个对开门一样（俯视时）的门板，该板的一侧通过合页固定在外箱内侧壁上，此合页的转轴低于外箱外沿，这样当水囊被注水膨胀时，顶开门板使其向外开启靠在侧壁上可对水囊起扶持作用。进一步的，还要把门板内面与水囊外表面进行粘合，这样当水囊水空缩瘪时，可以拉动门板关闭。
[0016] 如附图6所示：箱体内有两扇可以向上对开的门板（401），门板的转轴（402）固定于箱体的开口外沿以下，门板向上对开时倚靠箱体侧壁（404）以扶持软体水囊（400），门板内面粘合软体水囊（400）的外表面，软体水囊（400）水空变瘪时通过粘合处（403）拉动门板（401）关闭。效果：让洗车器外形小巧便捷的同时，又能满足大水囊的工作。
[0017] 三、水囊内置海绵，
原因：往水囊里抽水时由于出水管内充满空气，容易导致抽水困难或者一开始抽水慢，众所周知，水泵进水管通常都要注入引水才能优化抽水。基础方案中的产品，每次抽水之前若切换换向阀先喷水给出水管里充满水，再切换到抽水档位，则抽水会很高效便利。但是前提条件是水囊内必须有上次余下的水。
[0018] 措施：在水囊内放置一个海绵，为了避免海绵晃动堵塞进出水口，此海绵应该固定于水囊内壁上，例如固定在水囊内壁顶部；
效果：每次洗车完毕，海绵里都吸有水留给下次当引水，下次用时只要用手挤压即可。
[0019] 四、水囊上下双管，
原因：如附图1所示的基础方案中，水囊只接了一根水管既用来入水又用来出水。这有一个缺点，当该水管接在水囊底部时，随着水囊内水的增多导致水压的增大，注水速度会越来越慢。
[0020] 措施：如附图7所示，软体水囊具有一个位于上端的注水口（501）和一个位于下端的出水口（502），此两水口连通到二位五通换向阀。
[0021] 五、洗车照明，
原因：用户白天忙于工作无暇洗车；白天可能较炎热洗车累人；烈日下洗车时，水滴有凸透镜效果，容易聚焦日光灼伤车漆。因此要采取方便用户夜间洗车的措施。
[0022] 措施：洗车器可以搭载充电电池（蓄电池）作为电源。在水枪上安装电灯，该灯的灯光覆盖水枪喷出水花，该电灯通过电线连接洗车器的电源，该路电线绕在出水管外壁上，电线通过插头连接洗车器外箱和水枪上的电灯，该电路上设置一个开关控制电灯。
[0023] 效果：即使晚上洗车，也不必在路灯下进行了，并且灯光照射到水花，水花又起到折射作用，加强了灯光的覆盖面。
[0024] 六、列车串接技术，
原因：便携式洗车器其大小有限，尤其水囊大小有限，应付某些大车如大巴车力不从心。若是把洗车器做大，由于非便携产品销量有限，产量少会增加生产成本，要是把这些小的洗车器都串联起来做个大的用，那会很好。
[0025] 措施：洗车器尾部和头部设置挂钩，可以首尾相连，串联起来像列车一样。水路的连接：用另外一根更粗的水管将列车中各车厢的出水口都汇总起来。将两个挂钩设置到上盖的前后两端更好，这样上盖收纳时盖在外箱上，挂钩垂下可以当挂扣，扣住箱体。
[0026] 效果：即使一个大巴车司机也无需买专用洗车器了，他只要多买几个便携型洗车器，再多买一个汇总水管，把这些串成列车集中出水喷洒即可，水压更大，水量更多。
[0027] 七、出水管当拉绳：
同类产品中带脚轮可移动的洗车器通常具备一个拉手，供人牵引移动。本洗车器可不必设置此拉手，人们手握水枪绕车喷洒时，如附图1所示，出水管（5）的长度不足以绕车半周，出水管（5）承受人的拉力牵引洗车器随人移动。出水管的长度应当尽可能的短，通常2～3米左右很合适，不建议出水管的长度超过水泵的吸程；出水管上可设置利于手握的护套以增强用户体验。该方案可使洗车器更小巧便捷，利于收纳。
[0028] 洗车器的其他特征：
1.具有四个脚轮，其中两个前轮是能水平面上转动的转向轮，两个后轮是定轮；
2.水泵带压力开关，此开关可以根据水压控制水泵电路的开闭，此开关压力设置为小于撑破水囊的水压；
3.洗车时出水管承受拉力随人移动绕车喷洒；
4.水囊上不设置可开闭的注水口盖，也不设置提手；外箱上不设置任何拉手或者推手；
5.出水管和水枪等物件可以被收纳进外箱。
[0029] 产品优点：1.体积小便携。2.取水省力。3.水源兼容性好，无论是公厕洗手台，还是溪流池塘，均可取水。4.得益于电线自动收线盘和较短的水管，收纳方便。5.得益于进出水管的合二为一，双向水流起到滤网防堵塞功效，对水源洁净度要求低。6.抽水时不用人工灌入引水。7.还可以在车辆落水时，让空气充满水囊，起到救生气球的作用帮助不会游泳的驾驶员逃生，或者气囊浮出水面帮助指示车辆落水位置。

[0031] 具体实施：
基于本发明的洗车器产品设计示例：如附图1所示，产品主要由：软体水囊（1）、手动换向水阀（2）、盖板带轮外箱、电线自动收线盘（6）、电动水泵、水管（5）、水枪组成。软体水囊由软性材料制成，可折叠，工作时水囊全密封，水空后可收纳入外箱。
[0032] 其中盖板带轮外箱的外形和手提箱无异，特点在于其盖板（4）下安装有四个脚轮，并且盖板（4）可以完全取下，取下后，垫于箱体（3）的底部并通过挂扣固定，这样，在使用时，成为一辆小车，在收纳时，变成一个手提箱，大大提高便携性。
[0033] 其中电线自动收线盘（6）中电线的长度必须至少能满足绕车半周。使用前可以很轻松的将电线全部扯出，然后插头插入汽车点烟器。使用后只需按钮，即可由此盘中的弹性机构自动回缩收线。
[0034] 换向阀的水路连接如附图2或附图3所示，图中的二位五通手拉阀具有'R、A、P、B、S'5个水嘴，R与S接水囊，P接水枪，A与B分别接水泵的进水与出水。
附图4所示的水路工作，图中的203是二位五通手拉阀，其R口被堵住；并联时水从入口（201）分两路流动：
第一路：水经过一号泵（204）泵送到换向阀（203），阀的B口连通S口流到出口（202）；
第二路：水流到换向阀（203），阀的A口连通P口，经二号泵（205）泵送到出口（202）。
[0035] 串联时的水流：此时换向阀（203）的B口连通P口，阀的A口和R口连通，S口连通出口（202），很明显连通A口和S口的水管都不是通路；
水从入口（201）经一号泵泵送到换向阀（203），通过B口和P口后再经二号泵（205）泵送到出口（202）。
附图4结合附图1就得出附图5，图中301是水囊的上入水口，302是下出水口，两者都接到二位五通换向阀303上，该换向阀的切换使连接水枪300的出水管在加强水泵的泵送下向上入水口301注水，或者自下出水口302抽水。
[0036] 附图6中400是软体水囊，401是对开门板，其转轴402位于箱体侧壁404的外沿以下，向上翻开倚靠在侧壁上起到扶持水囊的作用。403是水囊外表面与对开门板粘合处，水囊水空收缩时，粘合处403拉动对开门板401关闭。箱体的纵剖面成倒梯形，这样便于箱体在生产时的仓储和运输。
[0037] 图下方的405是外箱上盖，通过剖面图可以看出其外形像托盘一样内凹，其凹面正好贴合箱体底面，托起箱体，其与箱体之间没有使用挂扣固定，而是使用磁铁吸合。上盖和箱体底部应开设排水孔为佳。安装在上盖下的406是脚轮，该脚轮通常为4个，其中前面的两个应该是可以在水平面上转向的转向轮，后面两个是非转向轮，这样使用灵活便捷。
[0038] 附图7所示的水囊，其中501是上入水口，502是下出水口。水囊内表面位于下出水口的位置，围绕出水口应该设置一圈浮点、疙瘩、齿状物之类的凸起，此举可以防止水囊快瘪时，两表皮吸合挡住出水口。503是固定在水囊内部上方的海绵，用来吸收余水供下次抽水时用作引水。504是可开闭的口盖，主要是方便清洗养护水囊，非必要。
[0039] 附图8展示了增强版洗车器的外观，图中：对开门板401的转轴402位于箱体侧壁404的外沿以下，倚靠箱体侧壁404扶持着充满水的软体水囊400。前控制面板上的6014是换向阀总拉手，其联动了两个手拉换向阀的同时工作，使抽水时双泵并联增加水量，而喷洒时双泵串联增加水压。
[0040] 洗车器内部安装有蓄电池，6012是电源开关；6013是洗车器出水口，使用快速接头连接出水管603。出水管上还带有接电插头6010用来插入接电插座孔6011，给水枪300上的电灯3001供电，出水管另一端的601是电插头，用来接电灯3001；602是水管快速接头用来对接水枪300。405是外箱上盖，垫在箱体下面通过磁铁407彼此吸合。406是带转向功能的脚轮。
[0041] 附图8中的洗车器还具有以下尺寸比例等特征：
1.上盖405的前后轮轴距大于或等于上盖的宽度，这样便于仓储运输时上盖的交叉堆叠；
2.上盖405盖在外箱上时，脚轮可收入箱体内，上盖是外箱六个面中的最大面，这样能营造长轴距和宽轮距以稳定承载水囊；若设计为上盖盖在箱体上时，4个脚轮位于箱体之外，形如抱住箱体，此种设计视为'脚轮可收入箱体内'；
3.出水管603的长度小于或等于水泵的额定吸程，且出水管的长度大于车辆高度，且出水管的长度不足以绕车半周，这样洗车器洗车时就不得不随人移动才能完整的绕车喷洒；
4.出水管和水枪等物件都可以被收纳进箱体内。
Technical Field
本发明涉及汽车清洗设备技术领域，特别涉及一种便携式电动洗车器。
 Background Art
当前市面上的便携式电动洗车器，多是采用硬质敞口水箱，具备可绕车喷水一周的数米长水管，使用时，从汽车点烟器接电，水箱放置不动，水枪随人绕车喷水。例如申请号：201120254219.6的“圆桶形手提式电动洗车器”。
这种洗车器有以下缺点：
1.体积大便携性差。2.取水靠手提，费力，尤其对女人而言。3.容积小，容积做大则便携性更差，难以放入某些小车的后备箱。4.必须将水桶放置在水龙头下面接水，取水麻烦，对水源挑剔，例如无法从加油站公厕的洗手台直接取水，需要用瓢舀水。5.由于水管冗长且使用时又在地面拖动磨损，沾上水和污渍，使用后收纳比较费事。6.带有灵活脚轮的洗车器放置在车辆后备箱中时，容易晃动造成异响给行车带来干扰。本发明旨在解决这些难题，同时还要解决下述问题。
一、基于节能环保的诉求，政府号召大家不要用自来水洗车，倡导用雨后积水，池塘河流水等非饮用水洗车。然而这种号召却得不到响应，其主要原因是：上述非饮用水洁净度不高，水中的细小杂质容易堵塞洗车器的滤网产生故障，而经常清洁和替换滤网又增加了时间和经济成本。二、由于取水累人又不方便，人们往往偷懒在水源处就地洗车，使得洗车后的污水污染了水源。
