Description
本发明涉及清洗技术领域,尤其涉及一种清洗设备。
本部分的描述仅提供与本发明公开相关的背景信息,而不构成现有技术。
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,由此带来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。家用洗车器有使用车载12V电源的便携式水枪,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。采用手动充气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。
基于上述洗车的各种不便,便携式压力清洁设备应运而生,其一般是通过例如柱塞泵产生高压水流来冲洗物体表面的。相对于前述的清洗方式,该便携式压力清洁设备虽然一定程度减少了用水量、节约了大量时间,但是目前的便携式压力清洁设备对水量和出水压力需求依然较高,且当在清洗例如汽车、厨卫和墙面时,不能快速的使用该便携式压力清洁设备。例如,汽车需要多角度、多清洗面的清洗,该便携式压力清洁设备仍然不能快速地接近每个被清洗的表面;同时还存在着车顶或禁止使用压力水流清洗的清洗面,此时,需要用户使用清洗布配合清洗。又例如,当在一些清洗场景中,需要握举该便携式压力清洁设备,并控制该便携式压力清洁设备多角度清洗,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洁设备的重力作用,操作体验感并不佳。此外,采用压力清洁设备将污垢剥离后,污垢会随着水流向下流动,如此,造成原本并不脏或不需要清洁的表面会被污染,而需要二次清洁。与此同时,在城市中用户洗车的场地受限,洗车后的污水的清理也是困扰用户的一个难题。
应该注意,上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明,并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。

如背景技术所述,现有技术中的便携式清洁设备以及洗地类清洁设备均不能兼顾多角度清洗和污水快速回收的双重要求。因此,针对此需求提出一种清洁设备。
如图1至图10所示,本发明提供一种清洗设备,包括清洁头10、手持架20和污水抽取机构30,其中:手持架20设有供操作者握持所述清洗设备的手握端;清洁头10设置在所述手持架20的一侧,所述清洁头10包括工作刷11、设置在所述工作刷11一侧的储水槽12,及用于回收所述储水槽12内污水70的吸污口124;污水抽取机构30包括抽吸通道301、及抽吸动力单元,所述抽吸通道301与所述储水槽12连通;其中,所述吸污口124包括第一吸污口1241和第二吸污口1242,所述污水抽取机构30能将承接在所述储水槽12中的污水70通过所述第一吸污口1241和/或所述第二吸污口1242进行回收,所述第一吸污口1241和所述第二吸污口1242分别位于所述储水槽12的长度方向的两端。
本发明的清洗设备,手持架20沿纵向方向Y设置以与清洁头10在纵向方向Y上拉开一定距离,便于手持操作,以使清洁头10能对待清洁表面如汽车100的车体表面进行清洁。当然本发明中的待清洁表面不限于车体表面,例如也可以是墙面等。
本发明中,“多清洗面”可以理解为清洗设备的清洁头10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10将呈现如图2、图4、图6多种不同使用姿态。例如,请参考图10,若以水平面(地面)为参考平面,清洁头10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10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,具有使用者手握清洗设备的手握端与地面的距离和清洁头10与地面的距离呈现不同结果的多个工作位置。例如,使用者可以握住手持架20,清洁头10整体相对于手持架20在竖直方向Z上处于靠上位置(如图9所示)、靠下位置(如图2、图3所示)、或者清洁头10与手持架20大致处于同一高度(如图6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9,可将清洁头10整体相对于手持架20在竖直方向Z上抬高,同时清洁头10的长度方向X的一端(如图9中靠近图面内侧的一端)相对于清洁头10的另一端在竖直方向Z上抬高以使得清洁头10的长度方向X与水平面形成夹角。
本发明的清洗设备,在具体使用时,清洁头10清洗的待清洁表面存在有坡度的情况,在清洁头10的长度方向X的两端,存在一端高、一端低的情况,即清洁头10的长度方向X的两端在竖直方向Z上高低不同,在该些状态下,储水槽12内存储的污水70能经由抽吸动力单元被抽吸 至对应的抽吸通道301内,能始终保持沿重力方向位于储水槽12下部(储水槽压低位置的一端)的吸污口与抽吸动力单元相连通,有效保证了清洗设备基于待清洁面的实际状况不同进行有效吸污的操作,提高本发明的清洗设备的使用场景的广泛性和实用性。
具体的,如图10所示,清洁头10包括工作刷11、及设置在工作刷11一侧的储水槽12,工作刷11用于对待清洁表面进行清洁,储水槽12用于收集清洁后的污水70,也就是说,污水70可以存储在储水槽12中。结合图1和图11所示,工作刷11包括骨架111、安装于骨架111的具有刷毛112的辊体113和电机114,电机114与辊体113传动连接以驱动辊体113带动刷毛112旋转,储水槽12和手持架20均连接于骨架111。储水槽12、骨架111二者可以为一体设置或者可拆卸连接。工作刷11具体配置为滚刷。
如图1所示,手持架20上还设有可为电机114提供电力的电池包40。电池包40可拆卸地设置在手持架20远离清洁头10的一端。电池包40具体可以为锂电,但不限于此。上述的纵向方向Y与工作刷11的轴向(也即辊体113的轴向)呈角度设置,具体地,二者彼此垂直。储水槽12沿工作刷11的轴向方向设置,其长度与工作刷11的轴向长度匹配,以能够收集到工作刷11轴向上各处的污水70。本实施例中,工作刷11的轴向即为清洁头10的长度方向X。工作刷11相对于手持架20在竖直方向Z上位置变化或相对于水平面发生角度变化时,可以认为清洁头10的工作角度发生了变化。
本实施例中的污水70指清洁后的废液体,对应的,清洁前的新鲜液体则称为净水,其中净水包括清水、含有清洁液的清水等,具体类型不作具体限定。具体使用时,工作刷11上浸有净水,净水的来源可以是将工作刷11在净水池中浸泡、在净水下冲刷、独立的喷净水的附件;或者如图1所示在手持架20上设置供水系统60,供水系统60能够实时地向工作刷11上喷射净水。工作刷11与待清洁表面如汽车100表面接触,通过与车体表面的挤压摩擦对车体表面进行清洗,污水70则流入储水槽12内。手持架20上设置供水系统60时,该清洗设备被构造为自动清洗设备,可以实现自动清洗且不受水源地点的限制,例如用户不必一定在近水源处进行清洗作业。
为了快速地将刷毛112上的污水70回收存储在储水槽12内,如图11和图12所示,骨架111上还安装有朝向辊体113延伸的去污单元,具体为刮水条13,刮水条13与刷毛112干涉,刮水条13位于刷毛112的转动路径上。储水槽12具有进污口123,该进污口123位于刮水条13的一侧且开口朝向刮水条13与刷毛112相干涉处。当清洗设备的角度为图1所示时,储水槽12的进污口123位于刮水条13的下方。如图11所示,清洗设备使用时,辊体113沿逆时针方向旋转,刮水条13的末端接触到刷毛112,不断地将刷毛112上的污水70刮至储水槽12内。通过设置刮水条13,提高了污水70回收效率,能够适应高要求的自动化清洗。
结合图1所示,刮水条13集成在一密封盖14上。密封盖14可拆卸地安装在骨架111上。密封盖14安装后,密封盖14刚好于上方将储水槽12遮蔽,使储水槽12的上部仅通过进污口123与外界相通。同时,刮水条13则朝向辊体113延伸并刚好与刷毛112干涉,从而可以将刷毛112上的污水70刮至储水槽12内。通过设置可拆卸的密封盖14,可以方便清洗储水槽12的内部。
如图1和图10所示,污水抽取机构30与储水槽12连通,能够将储水槽12的污水70转移出储水槽12,从而适应连续清洗作业的需求。
如图10至图12所示,为了能够使污水抽取机构30快速地将污水70转移,在清洁头10具有只在一个区域内设置吸污口的实施例中,具体的,在单一区域内的吸污口的数量可以为一个, 也可以为靠在一起的多个。吸污水储水槽12的内腔容积自储水槽12的进污口123至吸污口124的方向呈渐缩设置。
在一可行的实施例中,进污口123设置在储水槽12的上部,吸污口124位于储水槽12的下部并与外界连通,储水槽12呈上大下小状,也即储水槽12呈漏斗状或者呈锥状结构。于此,污水70自进污口123进入后,能够向储水槽12的下部汇流,从而储水槽12的下部能够有较高的污水70水位,便于污水抽取机构30的抽取。在本发明中,如图11所示,储水槽12的上部可理解为:储水槽12的位于储水槽12深度方向上的中心C以上的部分;对应地,储水槽12的下部可理解为:储水槽12位于储水槽12深度方向上的中心C以下的部分。可理解地,对于吸污口124而言,其位置越靠下越好。
如图11所示,储水槽12包括底壁121、连接于底壁121的侧壁122,侧壁122与底壁121围成储水槽12的内腔,进污口123开设于侧壁122,吸污口124则开设于储水槽12的底壁121。由于储水槽12呈上大下小的漏斗状,污水70能够向底壁121集中,从而便于污水抽取机构30的抽取。此外,如图10所示,吸污口124也可以是开设于侧壁122上靠近底壁121的位置,同样利于污水70的抽取。可以理解地,该清洗设备使用时,应当保证储水槽12至少部分地处于能够收集污水70的位置的前提下改变清洁头10的角度。具体而言,使储水槽12的进污口123至少部分地处于刮水条13与刷毛112相干涉处的下方。
在该实施例中,当清洁头10相对于手持架20在竖直方向上位置变化或清洁头10自身相对于水平面发生角度变化时,储水槽12相对于清洁头10发生位移,具体的,储水槽12能够相对于清洁头发生转动或者储水槽12本身的形态是可发生变化的,实现储水槽12内的污水70均能汇流至沿重力方向的储水槽12的下部,从而便于从沿重力方向位于储水槽12下部的吸污口124抽吸污水70。
当储水槽12的两端(参考图10中的A端和B端)在竖直方向Z上高低不同时,能够利于污水70的快速吸收。并且,当储水槽12的两端在竖直方向Z上高度相同时,也能利于污水70的快速吸收。而储水槽12的两端高度变化时,反映了清洗设备的工作角度在发生变化。因此,本实施例的清洗设备,能够满足多角度清洗且兼顾快速回收污水70的双重需求。
进一步的,如图10和图11所示,沿朝向手持架20的方向,储水槽12的内腔的横截面面积逐渐减小。也即沿与纵向方向Y呈锐角且靠近手持架20的方向,储水槽12的横截面积逐渐减小,使得储水槽12远离工作刷11斜向延伸并靠近手持架20。这样,在将清洁头10相对于手持架20在竖直方向上抬高或大致平齐时,污水70能够快速地向储水槽12的下部汇集,能够加快污水70回收。而且储水槽12是斜向延伸,因此,储水槽12更靠近手持架20上的污水抽取机构30,流入储水槽12的污水70能够靠近污水抽取机构30,利于缩短抽吸路径,从而加快污水70的回收。
如图12所示,在另一可行的实施例中,储水槽12还可以配置为包括能够跟随清洁头10的角度变化而改变形状的部分。具体的,储水槽12包括柔性的水袋101,能够随清洁头10的角度变化而变化形状,吸污口124设置在水袋101的袋底。其中图12中用虚线示意了清洁头10的角度变化时,水袋101的形状变化。具体地,当储水槽12中存储有污水70时,当清洁头10的角度变化时,在污水70的重力作用下,储水槽12的形状发生变化,使得储水槽12始终能够快速地收集并存储污水70,允许清洁头10在更多的角度范围内清洗。
在本发明中,在清洁头10具有在储水槽30的长度方向两端均设吸污口的实施例中,即在不 同区域上设吸污口。具体的,吸污口包括第一吸污口1241和第二吸污口1242。优选的,第一吸污口1241和第二吸污口1242的数量均为一个。当然,第一吸污口1241和第二吸污口1242的数量也可以分别为多个。第一吸污口1241和第二吸污口1242位于自所述储水槽12的长度的中心线向两端偏移预设距离的位置,所述预设距离配置为大于或等于所述储水槽12长度的1/4。优选的,如果第一吸污口1241和第二吸污口1242均配置为多个,其中储水槽30两端均至少有一个吸污口位于上述偏于预设距离范围内。其中,该第一吸污口1241和第二吸污口1242关于该中心线对称设置。其中中心线可以理解为基本位于储水槽长度方向(X方向)的中部。中心线与工作刷的旋转轴线相垂直。
进一步的,在吸污口的一可行实施例中,如图35所示,抽吸通道301包括第一进管3011和第二进管3012,所述第一进管3011和所述第二进管3012均包括伸入所述储水槽12内腔进行污水70吸收的进口端,所述第一吸污口1241和所述第二吸污口1242配置为由所述第一进管3011和所述第二进管3012的所述进口端形成。
在吸污口的另一可行实施例中,所述储水槽12包括围设形成储水内腔的外壳,所述第一吸污口1241和所述第二吸污口1242配置为贯穿至少部分所述外壳且与所述储水槽12的内腔连通的通孔,所述抽吸通道301连接所述通孔将污水70吸出。
在本发明中,清洁头10在以下至少一种使用姿态中具备:所述第一吸污口1241和所述第二吸污口1242中的一个被配置为供所述工作刷11产生的污水70流经;其中,所述使用姿态包括:所述储水槽12的长度方向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、以及所述第一吸污口1241和所述第二吸污口1242处于同一水平面的第二使用姿态。
根据本发明的一个实施方式,如图13所示,该清洗设备还包括切换机构50,所述第一吸污口1241位于所述储水槽12的长度方向的一端,所述第二吸污口1242位于所述储水槽12的长度方向的另一端,所述清洗设备处于所述储水槽12的长度方向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时,所述切换机构50构造为封闭所述第一吸污口1241与所述抽吸动力单元的通路,并打开所述第二吸污口1242与所述抽吸动力单元的通路。
在一可行的实施例中,所述切换机构50包括活动件51和驱动单元52,该驱动单元52能够驱动或控制所述活动件51运动,以封闭或打开所述第一吸污口1241和所述第二吸污口1242中的一个与抽吸动力单元的通路。
具体的,配合参阅图14和图15,活动件51包括设置在储水槽12内的一第一活动件和第二活动件,该第一活动件被配置为打开或封闭第一吸污口1241,该第二活动件被配置为打开或封闭第二吸污口1242。在本实施例中,第一活动件和第二活动件均为挡板511,两挡板511设置在储水槽12内且一一对应第一吸污口1241和第二吸污口1242设置。
在本实施例中,驱动单元52为重力感应单元,其可以是手动控制或者根据清洁头10的角度变化而自动工作。该驱动单元52为两个,每个驱动单元52包括分别与活动件51连接的弹性件521和重力块522,弹性件521被配置为提供使活动件51具有打开吸污口的运动趋势的弹性力;其中,在重力块522所承受的重力大于弹性力的状态下,重力块522能驱动挡板511(也即第一活动件和第二活动件中的一个)移动以打开对应的吸污口;在重力块522所承受的重力小于弹性力的状态下,挡板511(也即第一活动件和第二活动件中的一个)在弹性力的作用下关闭吸污口。也即,重力感应单元在对应的吸污口相对另一个吸污口被抬高时给予挡板511靠近吸污口的驱动 力,直到封闭被抬高的吸污口。
在本实施例中,弹性件521被配置为提供使挡板511远离吸污口方向运动的弹性力,重力块522所承受的重力大于弹性力。结合图14和图15所示,沿工作刷11的轴向,重力块522具有远离吸污口124的第一位置L1和靠近吸污口124的第二位置L2,第一位置L1靠近另一吸污口124。重力块522能在重力作用下在第一位置L1与第二位置L2之间切换,并且运动至竖直方向上第一位置L1和第二位置L2中位置靠下的一个。具体地,参考图14并结合图13所示,在竖直方向Z上,第二位置L2靠下,重力块522处于第二位置L2;参考图15并结合图13所示,当调转清洁头10使第一位置L1靠下时,重力块522在重力作用下运动至第一位置L1。
如图15所示,重力块522处于第一位置L1时,重力块522的重力传递至挡板511且其重力大于弹性力,挡板511封闭对应的吸污口。如图14所示,重力块522处于第二位置L2时,重力块522不作用于挡板511,弹性件521的弹性力使挡板511打开对应的吸污口。由于第一位置L1靠近另一吸污口,故当某个吸污口对应的重力块522的第一位置L1位于该重力块522的第二位置L2的下方时,则意味着竖直方向上,该吸污口处于另一吸污口的上方。因此,只要第一吸污口1241和第二吸污口1242在竖直方向Z上有高度差,则位置较高的吸污口所对应的重力块522将运动至其第一位置L1,从而实现将位置较高的吸污口封闭的目的;与此同时,位置较低的吸污口所对应的重力块522将运动至其第二位置L2,重力块522的重力不作用于挡板511,弹性力使挡板511打开吸污口。具体地,如图13所示,第一吸污口1241和第二吸污口1242上下设置,上方的第一吸污口1241被挡板511封闭,下方的第二吸污口1242则处于打开状态。
具体实施时,重力块522设置在储水槽12内,储水槽12内设有支点524,驱动单元52还包括柔性连接件523,该柔性连接件523的第一端与重力块522连接,该柔性连接件523的第二端从支点524的一侧绕过并连接至活动件51的靠近对应的吸污口的一端,在重力块522的重力大于弹性力的状态下,柔性连接件523张紧并承靠于支点524。
本实施例中,弹性件521优选为拉簧,拉簧始终给予挡板511拉力,使挡板511始终具有远离吸污口124的运动趋势。由此,当重力块522运动至其第一位置L1时,重力块522拉紧柔性连接件523,使挡板511沿与重力块522重力方向相反的方向运动,最终将吸污口124封堵。
较佳地,支点524设置为定滑轮,这样便于柔性连接件523在支点524上滑动。另外,较佳地,重力块522为球状,能够以滚动的方式在第一位置L1与第二位置L2之间切换。
在其它的实施例中,重力感应单元也可以是如下设置:弹性件521配置为始终给予挡板511推力,使挡板511始终具有关闭对应的吸污口的运动趋势。重力块522随着位置变化,能够将重力作用于挡板511克服弹性件521的推力以打开对应的吸污口,或者重力不作用于挡板511,使挡板511在弹性件521的推力作用下将对应的吸污口封堵。具体地,仍定义重力块522具有远离吸污口的第一位置L1和靠近吸污口的第二位置L2,第一位置L1靠近另一吸污口。重力块522能在重力作用下在第一位置L1与第二位置L2之间切换,并且运动至竖直方向上第一位置L1和第二位置L2中位置靠下的一个。在本实施例中,当重力块522运动至第二位置L2时,重力块522可抵压于挡板511,从而将挡板511压紧在对应的吸污口上,从而封堵该吸污口。反之,重力块522在第一位置L1,远离挡板511,重力块522不能将挡板511压向对应的吸污口,该吸污口处于打开状态。
上述实施例中,驱动单元52能够根据清洁头10的角度变化而自动驱动活动件51封堵位置 靠上的吸污口,从而在储水槽12的内外形成气压差,使得沿重力方向位于储水槽下方的吸污口能顺利抽吸污水70。并且在本实施例中,可以仅设置一个抽吸动力单元,节约成本,通过设置切换机构50,使沿重力方向处于储水槽12下方的吸污口自动打开,沿重力方向处于储水槽12上方的吸污口则自动封闭,从而在清洁头10的角度变化时仍保证能够快速地抽吸污水70。
在切换机构50的另一可行实施例中,如图16所示,驱动单元52包括角度传感器525和控制组件526,该角度传感器525能检测清洗设备的倾斜角度,控制组件526能根据角度传感器525的监测结果控制活动件51运动,以封闭位于储水槽12抬高位置的一端的第一吸污口1241与抽吸动力单元的通路,并打卡第二吸污口1242与抽吸动力单元的通路。其中,在本实施例中,角度传感器525可预先设置,以建立水平参考基准及与第一吸污口1241和第二吸污口1242的对应关系,从而当第一吸污口1241和第二吸污口1242在竖直方向上有高度差时,可以判断出谁的位置较高,谁的位置较低。
具体的,抽吸通道301包括三通管53,该三通管53包括第一输水管531和第二输水管531和至少一个出水管532,两个输水管531分别与储水槽12连通。其中第一输水管531和第二输水管531的数量可以为一个,也可以不止一个。在本实施例中,两个输水管531分别与抽吸通道的第一进管3011、以及抽吸通道的第二进管3012相连。当然,在三通管的的实施例下,三通管的第一输水管531和第二输水管531可以直接作为抽吸通道的第一进管和第二进管。活动件51包括两个阀门,也即第一阀门54和第二阀门55,两个阀门一一对应地安装于两个输水管531中;其中,控制组件526能根据角度传感器525的检测结果控制任一阀门封堵或打开对应的输水管531。
在本实施例中,角度传感器525检测到第一吸污口1241和第二吸污口1242的倾斜角度,控制组件526根据角度传感器525的监测结果控制在竖直方向Z上位置靠下的阀门打开,位置靠上的阀门封闭。具体地,角度传感器525和控制组件526均设置在主板上,然后安装于如图1所示的手持架20。当然,在其它的实施例中,角度传感器525也可直接与第一阀门54和第二阀门55建立对应关系,直接检测第一阀门54和第二阀门55相对于水平参考基准是抬高还是下降,进而利用控制组件526发出相应的动作指令。如第一阀门54位于下方时,第一阀门54所对应的吸污口也位于下方,此时打开第一阀门54,封闭第二阀门55,从而污水70向下方汇集,能加速污水抽取机构30抽取。当然,角度传感器525仍然可以是预先设置,建立水平参考基准及与两阀门的对应关系。
进一步的,控制组件526包括控制器和控制电路,控制器通过控制电路控制第一阀门54和第二阀门55运动。控制器的类型不限制,可以是嵌入式数字信号处理器(Digital Signal Processor,DSP)、微处理器(Micro Processor Unit,MPU)等。两个阀门可以是电动球阀,但并不限于此。
在该实施例中,两个阀门可以替换为能够相对输水管531运动以封堵或打开对应输水管531的元件。具体的,两个输水管531分别与第一吸污口1241和第二吸污口1242连通,出管532与污水箱32连通,该控制组件526能够控制活动件51往复运动以择一地将两个所述输水管531中的一个封堵。例如,如图16所示,活动件51位于左侧的输水管531并将其封堵,此时右侧的输水管531则处于打开状态。如图16虚线所示,活动件51向右运动时,活动件51将右侧的输水管531封堵,此时左侧的输水管531则处于打开状态。
此外,活动件51还可以是可转动地设置在输水管531内部,活动件51的转动平面垂直于输水管531的轴向,这样通过旋转活动件51,可以实现封堵或打开输水管531的目的。可以理解地,此时两输水管531内各设有一活动件51。例如,活动件51可以是电磁阀的阀体。控制组件526根据角度传感器525的监测结果控制相应的电磁阀的阀体将对应的输水管531封闭。
在一变形实施例中,如图17所示,与图16所示的实施例不同的是:活动件51包括电磁阀的阀体512,该活动件51能在两个输水管531之间往复运动,以择一地将其中一输水管531封闭,从而清洗设备在储水槽12的内外形成压力差,污水70在竖直方向上能从位置较低的吸污口处被抽吸。
在切换机构50的再一可行实施例中,储水槽12的两端分别设有第一吸污口1241和第二吸污口1242,该切换机构50构造为三通阀56,所述三通阀56包括分别与两个所述输水管531连接的两个阀进口562,以及和所述出管532连接的一个阀出口563,所述三通阀56具有内腔5611,两个所述阀进口562和所述阀出口563分别与所述内腔5611相连通;所述内腔5611中设有活动件564,其中所述活动件564被配置为能够朝向所述阀进口562运动以封闭位于所述储水槽12抬高位置的一端的所述第一吸污口1241与所述抽吸动力单元的通路,并打开所述第二吸污口1242与所述抽吸动力单元的通路。
具体的,该三通阀56具有阀体561,阀体561形成有内腔5611,两个阀进口562分别与位于储水槽12两端的第一吸污口1241和第二吸污口1242连通,阀体561具有内腔5611,两个阀进口562和阀出口563分别与内腔5611相连通;该阀体561的内腔5611设有:活动件564用于封堵两个阀进口562。
在本实施例中,活动件564包括第一活动件5641和第二活动件5642,分别用于封堵两个阀进口562与所述两个输水管531之间的通路;至少一个驱动单元565,置于两个第一活动件5641和第二活动件5642之间;在重力作用下,所述驱动单元565驱动所述活动件564运动,在其中一所述活动件564封堵相对应的所述阀进口562的状态下,另一所述活动件564与相对应的另一所述阀进口562分离,所述阀出口563与另一所述阀进口562连通。
具体的,在一可行的实施例中,如图18至图21所示,该驱动单元565为两个,位于第一活动件5641和第二活动件5642之间;在其中一活动件564封堵相对应的阀进口562的状态下,另一活动件564与相对应的另一阀进口562分离,该阀出口563与另一阀进口562连通。
在本实施例中,活动件564可为不锈钢球,驱动单元565也可为不锈钢球,且驱动单元565的外径大于活动件564的外径,以利驱动活动件564移动。
当清洗设备在顺时针倾斜状态下工作时,三通阀56的内部状态如图19所示,当污水抽取机构30打开时,三通阀56内部的四个不锈钢球会沿坡道下滑,对阀体561的阀进口562的压力为F=2×(M1+M2)g×sinθ,其中,90°≥θ≥0°,且M1为活动件564的质量,M2为驱动单元565的质量,单位均为克。此时右侧最底部的钢球对阀进口562形成了密封,储水槽12中的水由另一阀进口562进入,并从阀出口563流出,进入污水箱32,当污水箱32的污水漫过浮体331时,污水70会回流到储水槽12中。
当清洗设备在竖直状态下进行洗车工作时,三通阀56的内部状态如图20所示,当污水抽取机构30打开时,三通阀56内部的四颗不锈钢球会沿坡道下滑,右侧最底部钢球对阀进口562形成了密封,对阀进口562的压力为F=2×(M1+M2)g,此时储水槽12中的污水由阀进口562进入, 并从阀出口563流出,进入污水箱32,当污水箱32的污水70漫过浮体331时,污水70会回流到储水槽12中。
当清洗设备在水平状态下进行洗车工作时,三通阀56的内部状态如图21所示,当污水抽取机构30打开时,三通阀56内部的四颗不锈钢球对两个阀进口562、阀出口563形成不了密封,此时储水槽12中的污水70由两个阀进口562进入,并从阀出口563流出,进入污水箱32,当污水箱32的污水漫过浮体331时,污水70会回流到储水槽12中。
在另一可行的实施方案中,如图22所示,所述活动件564包括第一活动件5641和第二活动件5642,分别用于封堵两个所述阀进口562与所述两个输水管531之间的通路;驱动单元565为一个,位于第一活动件5641和第二活动件5642之间;三通阀56连接有摆动杆566,该摆动杆566与驱动单元565相连;在摆动杆566的摆动作用下,摆动杆566能带动驱动单元565朝向其中一活动件564运动以封堵相对应的阀进口562,另一活动件564远离另一阀进口562。
本实施例利用摆动杆566外部连接的摆锤567在重力作用下带动摆动杆566左右摇动,进而带动连接在摆动杆566下部的驱动单元565往相反的方向运动,以推动活动件564朝向阀进口562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561内部的各活动件564密封的阀进口562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56,依靠阀体561内的摆动杆566的自由摆动实现三通阀56的开启与闭合,步骤在于:活动件564由于摆动杆566下方的驱动单元565的挤压,两侧中的其中一侧活动件564与锥形管道内壁形成密封,实现阀进口562的开启与闭合切换,此时摆动杆566下方的驱动单元565对阀进口562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561的内腔壁面形成有供活动件564朝向对应的阀进口562移动的渐缩部5612。渐缩部5612的设置,利于活动件564朝向对应的阀进口562位移。
根据本发明的一个实施方式,所述清洗设备还包括污水箱32,所述污水箱32内的污水70能经由所述抽吸动力单元被抽吸至所述污水箱32内。
在抽吸动力单元的一可行实施方式中,如图10和图23所示,抽吸动力单元包括设置在污水箱32上游侧的污水泵31,清洗设备还包括驱动污水泵31抽吸运动的电机,污水泵31为两个,第一吸污口1241和第二吸污口1242分别通过一抽吸通道301与两个污水泵31相连通,两个污水泵31的出口分别通过一进污管与污水箱32相连通。
具体的,该污水泵31的入水口311通过抽吸通道301与第一吸污口1241/第二吸污口1242连通,该污水泵31的出水口312与污水箱32连通;当然,在其他实施例中,污水泵31也可为一个。
在本实施例中,污水泵31将储水槽12内的污水直接抽吸后排入污水箱32。在其他的实施例中,污水箱32可以省去,通过污水泵31的出水口312将污水70直接排放在指定位置。例如,污水泵31的出水口上连接有软管,通过软管将污水70排放至放置在地面上的指定容器内,从而避免污水70随意洒落而污染环境。
污水抽取机构30在抽取储水槽12中的污水70时,要求能够吸收污水70、且允许污水70及细小沙粒通过而不损坏污水泵31,同时污水70的流向最好为单向不能回流,且抽取时应当有 一定压力及能保证足够的流量,以保证抽取效率。此外,使用寿命也是一个重要的技术考虑因素,通常污水泵31的寿命要大于80小时。为此,在图10和图23的实施例中,污水泵31包括蠕动泵,蠕动泵能够满足上述诸多要求,继而清洗设备在多角度工况下使用时,污水抽取机构30仍然能够正常工作,兼顾多角度清洗及快速回收污水70的双重需求。当然,污水泵31也可包括隔膜泵,需要强调的是,这里所使用的隔膜泵中,隔膜片的要求应当满足或接近满足上述的对污水抽取机构30的多项要求。此外,可以在隔膜泵的上游增加过滤装置,避免长时间使用后细小沙粒等杂质对隔膜泵的腐蚀。进一步地,在设置过滤装置的情况下,隔膜泵可以替换为其他类型的水泵,在此不做具体限定。
由于储水槽12的两端分别设有第一吸污口1241和第二吸污口1242,虽然能够加快抽吸效率,但发明人注意到,在使用过程中,由于清洗设备存在多角度使用工况,会出现下面的问题:储水槽12两端的第一吸污口1241和第二吸污口1242在竖直方向上呈上、下设置,即第一吸污口1241和第二吸污口1242在竖直方向上具有高度差,此时污水70在重力的作用下会流向下方的吸污口,在图10所示的仅有一个污水泵31的实施例中,因只通过一个污水泵31分别对第一吸污口1241和第二吸污口1242抽吸,此时沿重力方向位于储水槽12上方的吸污口的空气抽吸相较位于储水槽12下方的储水槽12的污水70抽吸容易,无法形成气压差,导致沿重力方向位于储水槽12下方的污水70抽吸困难。
因此,在图10所示的实施例中,该清洗设备上还配设有上述切换机构50。在清洗设备的清洁头10的两端处于大体水平的状态下,污水泵31从第一吸污口1241和第二吸污口1242同时抽吸污水70,利于加快污水70抽吸;当储水槽12的两端的第一吸污口1241和第二吸污口1242在竖直方向上高低不同时,污水70会因重力因素向位置较低的吸污口汇集,从而在切换机构50的作业下,利于污水泵31快速抽吸储水槽12内的污水70。
而在图23所示的有两个污水泵31的实施例中,该清洗设备上可配设有上述切换机构50,也可不设置上述切换机构50,仅通过控制与对应吸污口相连通的污水泵31的启闭即可实现在清洁头10处于不同姿态下的使用及污水回收效果,在此不作限制。
在抽吸动力单元的另一可行实施方式中,所述抽吸动力单元包括设置在所述污水箱32下游侧的负压发生机构35,所述负压发生机构包括一个气泵,所述清洗设备包括驱动气泵抽吸运动的电机,所述气泵的入口与所述污水箱32连通。即污水箱32置于负压发生机构35与吸污口之间,该负压发生机构35用于在污水箱32的内部形成真空,使得污水70不断地被抽取到污水箱32内存储起来。在该实施方式中,污水70不会进入负压发生机构35。
在一实施例中,如图24所示,储水槽12两端的吸污口124分别通过抽吸通道301与污水箱32相连通,负压发生机构35的进气口351与污水箱32连通,负压发生机构35的出气口352与储水槽12连通。在该实施例中,负压发生机构35可以为任意的能够在污水箱32的内部形成真空负压的装置,具体地,负压发生机构35可为隔膜泵、蠕动泵、柱塞泵或电磁泵,其数量可为一个或两个。在本发明中,污水箱32和气泵的进气口351之间可增加过滤结构,以提高气泵的使用寿命。
在另一实施例中,如图25所示,储水槽12两端的第一吸污口1241和第二吸污口1242分别通过抽吸通道301与污水箱32相连通,负压发生机构35的入口与污水箱32连通,该负压发生机构35为风机。
根据本发明的一个实施方式,清洗设备至少具有手握端距离地面高度大于工作刷11距离地面高度的第一工作位置、以及手握端距离地面高度小于工作刷11距离地面高度的第二工作位置;输送至污水箱32内的污水70能够对污水箱32内的气体施加压力,污水箱32设有排气结构33,该排气结构33具有输送污水箱32内的气体向外导出的排气口333,该排气口333响应于清洗设备的工作位置的变化而进行排气口333位置的调整,以实现排气口333暴露于污水箱32内的污水液面的上方。
在图10、23~25所示的实施例中,排气口333设置在污水箱32内,该排气结构33包括浮体331、与浮体331连接的连接管334,浮体331具有通气孔道,通气孔道的一端形成排气口333并位于污水箱32内的液面的上方,通气孔道的另一端通过连接管334将气体向外排出。
具体的,浮体331的密度小于污水70的密度,能够漂浮在污水70液面上,污水箱32内的气体从排气口333进入并排出污水箱32。
进一步的,为了避免出现污水箱32内汇集的污水70进入排气口333,该浮体331上设有配重块332,该配重块332位于连接管334的端部,该配重块332的重力小于浮体331在污水70中的浮力。
具体的,配重块332设置于浮体331的背对排气口333的一侧表面,配重块332所承受的重力小于浮体331在污水70中的浮力。这样,当清洗设备处于不同使用状态时,排气口333始终能够背对污水70。较佳地,连接管334具有一定的柔性,这样清洗设备转换角度时,浮体331在调整排气口333的位置时可以不受连接管334的制约。
如图26和图27所示,当浮体331上设置有配重块332时,清洗设备处于不同工作角度时,排气口333的开口始终能够背对污水70,避免污水70进入到连接管334中。如图27所示,相对于图26而言,清洗设备倾斜,此时在配重块332的作用下,连接管334弯曲,排气口333的开口沿竖直方向朝上设置。
较佳地,浮体331为空心结构,其具有内腔。排气口333与空心的浮体331的内腔连通,同时和配重块332位于浮体331的同一直径上且位于浮体331的球心的两侧。连接管334的一端插入到空心的浮体331的内腔中。本实施例中,浮体331不限于空心结构,只要排气口333及连接管334能够彼此连通即可。在本实施例中,连接管334可从配重块332中穿过并插入到浮体331中,当然连接管334也可以从浮体331的其他位置插入浮体331的内部,在此不做限制。
本发明的清洗设备,在图10和图23所示的实施例中,污水箱32内的气体可通过返气管34连通至储水槽12的返气口125,以使污水箱32的内部空间与储水槽12连通。如此,污水箱32内的气体可回流至储水槽12内,避免污水箱32内压强过大而使得大量污水70回流至储水槽12,也可避免污水箱32内压强过大而导致污水箱32损坏,同时避免污水箱32滴漏污水70;另外,污水箱32内的气体回流至储水槽12内后一定程度上增加了储水槽12内的压强,利于将储水槽12内的污水70快速被抽取。
在图24所示的实施例中,排气结构33的连接管334通过管路与负压发生机构35的进气口351连通,负压发生机构35工作时,通过排气口333抽取污水箱32内部的气体,该排气结构33能够使负压发生机构35较为可靠地抽取污水箱32内部的气体继而形成真空负压,避免污水70意外进入负压发生机构35。
另外,发明人还考虑到即使设置浮体331避免污水70进入负压发生机构35,然而污水箱32 内的气体不可避免的会含有少量的水气,这将导致负压发生机构35排出的气体中含有少量的水,这些水可能对环境造成污染。为此,本实施例中,负压发生机构35的出气口352还通过返气管34与储水槽12连通,通过上述手段,一方面将多余的水汽排入储水槽12,避免污染环境;另一方面,负压发生机构35排出的气体进入到储水槽12中后,一定程度上增加了储水槽12内的压强,利于负压发生机构35将储水槽12内的污水尽快抽取。
具体设置返气管34与储水槽12的对接时,该返气管34可以直接经由返气口125插入储水槽12的内腔中。当然,在其他的实施例中,该返气管34也可以是与储水槽12的返气口125通过接口连接,在此不作限制。
在图28所示的实施例中,该排气口333设置在污水箱32上,污水箱32能够响应清洗设备不同工作位置的变化转动设置,以使在不同操作位置下该排气口333均位于污水箱32内的液面的上方。
具体的,手持架20上设有自适应接头16,污水箱32通过自适应接头16连接于手持架20,使得污水箱32始终保持与水平面平行。如此,在“多维度”的清洗中,污水箱32始终保持与水平面平行,有利于保持排气结构33的浮体331的姿态,从而防止污水70的回流和外泄。
由上述介绍可知,本实施例的清洗设备,储水槽12的两端在竖直方向上高度相同时,能保证利于污水70快速吸收。而可以理解地,在储水槽12的两端在竖直方向上高低不同时,污水会自然地向其中一端流动,同样能够利于污水70快速吸收。而储水槽12的两端在竖直方向上的高度变化时,说明清洗设备的工作角度在发生变化。因此,本实施例的清洗设备,能够满足多角度清洗且兼顾快速回收污水70的双重需求。
在使用过程中,也会出现储水槽12的两端在竖直方向上高度相同时的工况,为了保证这种情况下也能较快的吸收污水70,如图29所示,储水槽12的底壁的中部高、两端低以使污水70能够自中部向两端的第一吸污口1241和第二吸污口1242流动。更具体而言,参考图30并结合图29,储水槽12包括底壁121、连接于底壁121的侧壁122,侧壁122与底壁121围成储水槽12的内腔,其中,在工作刷11的轴向上,底壁121的中部高、两端低,以使污水70能够自中部向两端流动。由于储水槽12的底壁的中部高、两端低,当储水槽12两端在竖直方向上高度相同时,污水70会同时向两端的吸污口124流动,从而利于污水70抽吸。
储水槽12的底壁121的中部高、两端低,如图29所示,底壁121包括第一引流面126和第二引流面127,第一引流面126和第二引流面127分别为斜面,在储水槽12的深度方向上(图29中为上下方向),斜面的顶端12a较斜面的底端12b更靠近储水槽12的中部,两斜面在工作刷11的长度方向X上排列,且两斜面的顶端12a连接。从而自第一引流面126和第二引流面127相连接处,污水70更容易向第一引流面126远离第二引流面127的一端流动、以及容易向第二引流面127远离第一引流面126的一端流动。结合参考图23和图29,第一吸污口1241和第二吸污口1242均设置在储水槽12的侧壁122上,且两个吸污口124分别靠近第一引流面126远离第二引流面127的一端、第二引流面127远离第一引流面126的一端。
在其他的实施方式中,如图31所示并结合参考图29,第一吸污口1241和第二吸污口1242可以分别设置在第一引流面126和第二引流面127上。较佳地,两个吸污口124分别设置在靠近第一引流面126远离第二引流面127的一端的位置、以及靠近第二引流面127远离第一引流面126的一端的位置。换言之,在本实施例中,第一吸污口1241和第二吸污口1242分别设置于第一引 流面126和第二引流面127中靠近彼此远离一端的位置。
需要强调,储水槽12的底壁121的中部高、两端低不限于上述的实施方式,利于污水70从储水槽12的底壁121的中部向两侧流动的任意结构均可。例如,上述的斜面也可为波浪面,相邻波峰之间形成导水槽。
如图32所示,储水槽12的返气口125开设于储水槽12的侧壁122,且在工作刷11的轴向上,返气口125位于第一吸污口1241和第二吸污口1242之间。也就是说,返气口125开设于储水槽12的侧壁122在工作刷11的轴向上的中间位置,从而在将少量的污水70送入储水槽12的同时,气体能够加速污水70向两端的第一吸污口1241和第二吸污口1242流动。需要强调,储水槽12的返气口125开设于储水槽12的侧壁122,也适用于储水槽12的底壁121为平坦面。
结合图33所示,本实施例的清洗设备使用时,通过供水系统60向刷毛112上喷水,工作刷11逆时针转动,刮水条13将刷毛112上的污水70刮进储水槽12内,污水70会向储水槽12的两端流动,然后被两个污水泵31抽吸后送至污水箱32。供水系统60喷出的净水及污水70的流向可参考图中箭头所示。污水箱32内的空气通过连接管334返回至储水槽12。在图32所示的实施例中,污水70从储水槽12的底壁121上的第一吸污口1241和第二吸污口1242被抽出,然后被两个污水泵31抽吸后送至污水箱32。供水系统60喷出的净水及污水70的流向可参考图中箭头所示。污水箱32内的空气通过连接管334返回至储水槽12。
如图33所示,在图10所示实施例的清洗设备的基础上,手持架20上进一步设置有供水系统60。供水系统60包括清洁液箱61、清洁液泵62,其中清洁液箱61也设置在手持架20上,清洁液泵62可与手持架20分体设置或者也设置在手持架20上。清洁液泵62连接有抽液管路63及喷射管路64,其中抽液管路63伸入到清洁液箱61内;喷射管路64的喷口641则位于刷毛112的一侧,如图32所示。如此,本实施例的清洗设备仅通过清洁液箱61内存储的液体即可完成车体表面多角度工况下的清洗,不需要搬运大量的水,使用非常方便
如图34,本发明的清洗设备的又一实施例中,与图24所示的实施例的不同在于污水抽取机构30的构成不同,其中储水槽12的结构类似,即储水槽12的底壁的中部高、两端低,污水70能够向两端流动,利于污水70抽吸。
本实施例中,污水抽取机构30包括两个污水箱32、两个负压发生机构35,其中两个污水箱32分别与两所述吸污口124连通,两个负压发生机构35分别与两个污水箱32的内部空间连通。即每个吸污口124均单独配置一个污水箱32及负压发生机构35,能够保证高效的抽吸储水槽12内的污水70。
两个污水箱32可以是在一个较大尺寸的水箱内设置隔板将该水箱内部分割成两部分而成,也可以是两个彼此分离的水箱,具体方式不限制。负压发生机构35的类型不限制包括大隔膜泵、蠕动泵、柱塞泵、电磁泵或风机。
另外,与本实施例中,每个污水箱32内均可以设置前述的排气结构33,排气结构33与对应负压发生机构35的连通方式与图24中类似,不再赘述。
另外,每个负压发生机构35的出气口352通过返气管34与储水槽12的同一返气口125连通,一方面将多余的水汽排入储水槽12,避免污染环境;另一方面,负压发生机构35排出的气体进入到储水槽12中,一定程度上增加了储水槽12内的压强,利于负压发生机构35将储水槽12内的水尽快抽取。每个负压发生机构35也可以是单独地与储水槽12的不同返气口125连通。
本发明还提供一种清洗设备,包括手持架20和清洁头10,其中:手持架20沿其纵向方向延伸设置;清洁头10包括清洁头壳体及可转动地连接在所述清洁头壳体上的工作刷11及用以收集污水70的储水槽12,及用于回收所述储水槽12内污水70的吸污口124,所述清洁头壳体上设有去污单元,所述去污单元被配置为作用在所述工作刷,以将所述工作刷上的污水70去除并导引至储水槽12;如图36所示,其中,所述吸污口124包括设置在所述储水槽12的长度方向一端的第一吸污口1241,所述第一吸污口1241被构造为使所述储水槽12的内腔向所述长度方向上的自由端敞开设置。
具体的,该实施方式中,去污单元例如可为实施方式一中的刮水条13。
在该实施例中,第一吸污口1241被构造为使所述储水槽12的内腔向所述长度方向上的自由端敞开设置,该敞开是指污水能沿某一方向向外流出,而不是指储水槽12内腔在该方向与外界之间没有任何实体结构。如果储水槽12长度方向的自由端没有形成连续的将该方向完全覆盖的实体结构,使污水70不能沿该方向流出,就认为储水槽12内腔在长度方向的自由端是敞开的。本发明采用该种结构,省去了设置污水抽取机构,该清洁头10在多角度下进行操作时,通过去污单元收集至储水槽12中的污水能顺势从第一吸污口1241和第二吸污口1242被排出,简化了该清洗设备的结构,提高了使用便利性。
进一步的,第一吸污口1241和第二吸污口1242向外敞开的部分在纵向方向Y的周向上的圆周弧度大于等于2度,更加利于污水70的排出。更进一步的,如图37所示,储水槽12设有遮挡板,该遮挡板能遮盖部分吸污口。
为了储水槽12内能积累一定量的水后再向外流,本发明还包括能够封堵第一吸污口1241和第二吸污口1242的堵头,在用户不使用该清洗设备时,用以封堵第一吸污口1241和第二吸污口1242。
在本发明的一个实施方式中,手持架20可通过一软管102与清洁头10相连,如图38所示,其中,污水抽取机构30、供水系统60、以及对应的连接管路等均设置在手持架20内,该实施例中,操作人员可通过一手提握手持架20,另一手握持软管102,实现清洁头10多维度的清洗操作,而手持架20内的污水抽取机构30的污水箱32不会受多维度操作影响,而出现污水外漏的风险,提高了本发明的清洗设备的使用灵活性。
本实施例的清洗设备与实施方式一的清洗设备的结构、工作原理和有益效果基本相同,在此不作赘述。
以上所述的具体实施例,对本发明的目的、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,以上所述仅为本发明的具体实施例而已,并不用于限定本发明的保护范围,凡在本发明的精神和原则之内,所做的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
