Description

清洁工具、控制助力的方法及实现方法的装置 技术领域
本公开大致涉及一种清洁设备，特别是使用助力推动，用于清理平整地面上的干垃圾、湿垃圾，以及包括黏性垃圾在内的混合垃圾的清洁工具、控制助力的方法及实现方法的装置。
背景技术
通常人们清洁地面，使用的工具是扫帚、拖布、地板擦等，这些工具主要是依靠人们的手动操作来完成清洁工作。随着科技的进步，人们对地面清洁工具的要求也逐渐提高。
首先出现的是吸尘器，其工作原理是“气尘环流”，即依靠电力供能，通过产生负压来吸取地面上的垃圾、灰尘等。但吸尘器由于其工作原理的限制，使其无法清理牢固贴附在地面的一些垃圾和污渍，一旦有液体进入吸尘器，很容易造成吸尘器损坏。因此现又出现了新的地面清洁器。该新的地面清洁器通过电机的运行带动清洁筒(清洁辊)擦拭地面，清洁筒通常采用海绵筒或者百洁布。同时该地面清洁器内也会配备供水系统和水槽，对清洁筒进行清洗，从而完美地实现对地面的清洁。清洗后的海绵筒通常会通过挤水件将其内的水分，否则水分会在海绵筒与地面挤压时流到地面上。
对于自重较大的清洁工具，人们通常配备电机驱动，但是电机驱动结构类似于机动车，结构复杂，且造价高，对于一些小型的清洁工具并不适合。操作小型清洁工具的多为老人、女性，控制过于复杂，也不符合消费群体的操作。
并且，在家庭居室和厨房的垃圾，具有干湿垃圾混合，且可能存在各种汤汁(糖浆、番茄酱等)等黏性垃圾混合的情况，现有清洁工具对于黏性垃圾，特别是干垃圾、湿垃圾和黏性垃圾的混合垃圾无能为力、束手无策。
背景技术部分的内容仅仅是公开人所知晓的技术，并不当然代表本领域 的现有技术。
概述

本公开在拖把杆上装配助力识别结构，通过操作者作用在拖把杆上的力的大小变化，方向变化，能够灵敏的感应操作者的意图，从而控制电机驱动清洁工具做出适应性变化，设计更人性化。

以下结合附图对本公开的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本公开，并不用于限定本公开。
本公开涉及的清洁工具，用于清洁地面，特别是光滑平整的小面积地面，如家居与厨房地面。本公开清洁工具特别适合清洁混合有干垃圾、湿垃圾以及如面条、粥、番茄酱等粘稠物的混合垃圾。
本公开所述干垃圾特指颗粒状垃圾，如果皮、瓜子壳、米粒、纸片等。
湿垃圾为液体类垃圾，如水、饮料等。
黏性湿垃圾包括汤、羹、粥、番茄酱、巧克力酱等具有一定粘稠度的半固体垃圾。
其他垃圾还有如灰尘，地面印记等，也是本公开的清洁对象。
图1为本公开清洁工具一实施例的立体示意图，图2为清洁头的爆炸图；图3为清洁头内部结构示意图；图4为截面示意图，图5为清洁头底面示意图，图6为清洁头侧面示意图。结合图1至图6所示，本公开的清洁工具包括相连接的清洁头和手持部。手持部包括清洁杆301，延长杆302，清洁杆301和延长杆302通过连接结构304连接。清洁杆301通过铰接结构305与清洁头连接。操作者通过手持部带动清洁头在地表移动，将地表散落的各种垃圾清理干净。
本公开清洁工具的清洁头包括壳体500，在壳体的底部以及壳体内部安装有清洁模块，清洁模块将垃圾从地面分离，并在壳体内分离。在壳体底面，安装有轮子190，减少非清洁模块与地面的接触，使得拖动更省力。
清洁模块包括设置在壳体的底部的拖扫单元110，与拖扫单元并列设置的挤压单元120，设置于拖扫单元后方用于储存干垃圾的干垃圾收集单元150，设置于干垃圾收集单元150入口处的清理单元130，污水收集单元140和净水供给单元160。
其中，拖扫单元110包括滚筒111，铲条112，滚筒驱动机构113和滚筒传动机构114。滚筒驱动机构通过滚筒传动机构驱动滚筒111在图4中逆时针绕其轴线旋转。铲条112固定在壳体500上，具有弧形工作面，弧形工作 面与滚筒111的外圆周之间形成距离均匀的缝隙。
滚筒111包括内层的硬胶和包裹在硬胶外面的海绵层。硬胶的端头可通过轴承等连接件固定在壳体500上。滚筒驱动机构113驱动通过滚筒传动机构114驱动硬胶绕其轴线自转，带动海绵层自转，使得海绵层的表面作圆周运动。
当滚筒111在地面滚过，地面上的干垃圾的颗粒将海绵层压迫、变形，海绵层通过变形将干垃圾的颗粒包裹，使得干垃圾的颗粒与地面分离，随滚筒111一起转动。当转到铲条112位置处，干垃圾的颗粒离开地面，受铲条112的挤压，继续随滚筒111一起转动。当转过铲条112，转到干垃圾收集单元150入口处时，由于失去铲条112的压迫，海绵层111b的恢复变形，将其包裹的干垃圾颗粒释放，弹入干垃圾收集单元150内。
挤压单元120的轴线与滚筒111平行设置，可以通过两端固定在壳体500上，或通过卡扣结构固定在壳体500上。挤压单元120的硬度远大于海绵层111b的硬度。挤压单元120与滚筒111轴线间的距离小于二者半径之和，因此，装配后挤压单元120挤压滚筒表面。在挤压单元120面向滚筒111的位置形成挤水区B。
图7是挤水区形成示意图，如图7所示，挤压单元120与滚筒111干涉，在干涉处对滚筒的海绵层111b进行挤压。在图中，滚筒111顺时针旋转，在图中挤压单元120的下方形成挤水区B。滚筒海绵层111b上携带的水，经过挤压后流出，被污水收集单元140收集起来。当滚筒经过湿垃圾后，海绵层携带湿垃圾继续顺时针旋转。在滚筒上，从接地点M(与地面接触的位置)至挤压点N(与挤压单元120接触的位置)之间的海绵层包含污水，经过挤压单元120的挤压，污水在挤水区B离开海绵层，被污水收集单元140收集，使得经过挤压点N的海绵层的含水量是不饱和的，在再次旋转到M点与地面接触时，可以继续吸水，这样，清洁工具可以持续的吸收地面的积水，避免海绵饱和不能有效吸水。
本公开的清洁工具还包括净水供给单元160。净水供给单元160将净水 直接或间接送到海绵层111b上。净水进入海绵层内部，在被挤压单元120的挤压时从海绵层溢出，将海绵层111b的表面附着的污物剥离，以此将滚筒表面清洗干净。
当滚筒滚过地面的黏性湿垃圾时，黏性湿垃圾附着在海绵层111b的表面。净水供给单元160提供的净水，将附着在海绵层111b的表面的黏性湿垃圾层冲掉。
为了保持挤压后的海绵层的相对干燥状态，净水供给单元160将净水出口设置在挤水区。在挤水区海绵层111b吸收净水，变成饱和状态，再经过挤水单元120的挤压，将海绵层锁住的、从地面吸附的湿垃圾和水排出，液体排出的过程，带走海绵层111b表面的黏性湿垃圾，使得海绵层111b表面保持洁净。因此，本公开无须操作者动手或中断清洁工作，就能达成滚刷111表面的清洁，在推动滚轮的过程中，与地面接触的滚刷表面都是干净的。
本公开还包括清理单元130。清理单元130设在干垃圾收集单元150入口上方。当滚筒表面转过铲条的上端到了干垃圾收集单元150入口后，其表面附着的固体垃圾，不能借助海绵的弹性和自重脱离海绵层111b，清理单元130将其刮下，被刮下的垃圾在自重作用下下落，落入干垃圾收集单元150。清理单元130特别适用于一些轻小容易附着的垃圾，如纸片等。清理单元130保持海绵层111b的表面没有干垃圾。
本公开的清洁工具还包括水循环模块200，水循环模块200包括管路连接的污水收集单元140和净水供给单元160。污水从滚筒111挤压出来，挤压出的污水经过管路被收集至污水收集单元140，经过净化后进入净水供给单元160，再次循环利用，再次喷淋到上述挤水区，对滚刷进行清洗。
本公开的有益效果在于：
使用本公开清理地面，湿润的外层海绵接触地面，不会使地面的灰尘扬起，具有普通拖把的效果，防止二次污染；
外层海绵与铲条相互配合，能够将固体垃圾完全收集；
清理单元将附着在外层海绵的固体垃圾分离，收集，保持外层海绵表面 没有固体垃圾；
滚筒吸收地面湿垃圾，当其内的水被挤出时将滚筒表面附着的黏性垃圾剥离、冲淡，溶于水的部分被带入污水箱，不溶于水的被从滚筒上剥离，进入固体垃圾箱，从而能够处理黏性垃圾，并将干、湿垃圾分离；
挤压单元将外层海绵内锁住的液体挤出，保持外层海绵的不饱和状态，从而使得清洁工具能够持续清理液态垃圾；
净水供给单元和挤压单元共同作用，可保持接触地面的滚轮始终是清洁状态；
因此，本公开可清洁黏性湿垃圾，特别是各种垃圾的混合，并能够分离干湿垃圾，持续保持滚筒的外层海绵表面清洁。
本公开的各零部件，以及零部件的组合关系不唯一，下面进行逐一说明。
滚筒的实施例
图8为本公开一个实施例的滚筒结构示意图。如图8所示，滚筒包括位于轴心的硬胶111c和被包裹固定在所述硬胶的圆周面的海绵层111b。
海绵的密度、硬度对吸水性能和蓄水率(也称锁水性)有直接影响。当海绵密度在一定程度上提高，吸水性能会降低，硬度会提高，蓄水率会提高；反之，海绵密度降低，吸水性会提高，硬度会降低，蓄水率会降低。
本实施例的滚筒只具有唯一海绵层，海绵层111b为聚乙烯醇(polyvinyl alcohol,vinylalcohol polymer，简称PVA)发泡制得。PVA海绵的密度为0.5-0.25g/cm 3，吸水率为0.5-1.5g/cm 3。PVA海绵的邵氏硬度A为40-70。PVA海绵的蓄水率为0.2-1.0g/cm 3。本公开的海绵层，因其具备上述特性，因此与现有单层普通海绵滚筒对比，具有更优的效果：
海绵层既具备合适的吸水性能、蓄水率，同时具备合适的密度和硬度，这使得在拖地过程中，海绵能够的变形恰到好处，将垃圾颗粒包裹，并在转过铲条限制时，能够利用自身弹性，将大多数的垃圾颗粒弹出，脱离海绵层，落入干垃圾收集单元中，不至于有遗漏；并且，在处理地面的积水时，海绵 能够吸收较多的水，而拖过的底面残留较少的水。
本公开的单层海绵层，不会出现双层海绵之间因被挤压脱离起层，而影响滚筒的寿命的弊端。
挤压单元的实施例
本公开的挤压单元包括一个与滚筒并列设置并干涉设置的长条形物体。长条形物体固定在清洁头的壳体上，干涉滚筒，长条形物体的硬度大于滚筒表面海绵层的硬度，可压迫海绵层做变形。挤压单元可以有不同的物理结构，各具优点。
如图9中的挤压单元，包括固定座125和条状凸起126。通过固定座将挤压单元固定在壳体上。当滚筒111绕自身轴心旋转时，条状凸起126不动，通过条状凸起的海绵层被挤压变形，海绵层锁住的大部分水分被挤压出海绵表面，向下流走。
挤压单元可以为呈圆柱状的挤压辊。依靠两端固定在清洁头上。挤压辊的表面可以是光滑的，也可以在带有螺旋形的凸起。
图10为挤压辊的一个实施例结构示意图，如图10所示，本实施例的挤压辊121包括辊体121a，呈圆柱状，通过两端安装在清洁头的壳体上。辊体121a的圆周表面带有螺旋凸起，为了与滚筒上的螺旋凸起做称谓上的区别，可称之为第二螺旋凸起121f。挤压辊圆周面上的螺旋凸起数量为一条，沿挤压辊的一端延伸至另一端。
图11为挤压辊的另一个实施例结构示意图。该实施例与图10所示实施例不同的是，第二螺旋凸起121f为两条，从辊体121a两端的同一母线开始，以相反的螺旋方向向辊主体的中部延伸。
在本实施例中，在辊体121a中部设，两条第二螺旋凸起121f的中间位置，有与辊体121a轴向平行的直线凸起121g，直线凸起121g可以与两条第二螺旋凸起连接。
如此，可以在此处辊体121a的表面形成一个封闭的侧壁。
螺旋凸起的侧壁可以起到推水的作用，帮助把挤压辊压出的污水推至所设置的污水口。
图10所示的挤压辊配备在污水口位于侧边的清洁头，图11所示的挤压辊配备在污水口位于挤压辊中间的清洁头。
图12为螺纹导水的示意图。图12中水的流动方向如箭头所示，滚筒111顺时针转动，挤压辊121逆时针转动，在挤压辊121与滚筒的夹角处形成挤压后的水槽。净水口在机器的右端，抽水口在机器的左端，为了让水快速流动，在挤压辊121处增加螺纹，此螺纹的侧面可以起到推水的作用，使水流得更快，避免堆积，水面升高溢出壳体。
在污水口和净水口分别位于清洁头相对两侧的清洁工具里，为了加快水的流动，在滚筒旁还设置有二级水槽。
挤压单元与滚筒干涉，挤出的水存在两者之间，形成水槽。可以在滚筒表面喷淋净水，或者将净水注入该水槽内，对滚筒表面进行清洗。挤压单元设置的位置，考虑水槽的形成位置。
本公开将挤压单元相对于壳体静止不动称之为静态挤压。静态挤压的结构简单，挤压单元可以直接与机器主结构件做成一体。在设计时更加的方便。
挤压单元可固定不动，也可自转。
挤压辊可以配备动力机构，主动挤水，也可以节约成本，不配备动力机构，依靠滚筒的摩擦力自转。
可以在清洁头的壳体上固定第一电机，第一电机连接挤压辊，驱动挤压辊旋转。
清理单元的实施例
本公开的清理单元可以有多种形式。
滚刷组件实施例
图12清理单元为滚刷组件。如图所示，滚刷组件包括滚刷轴、刷毛131a。 刷毛131a设置在滚刷轴的圆周面上。图12显示的刷毛呈V字形排列，滚刷组件是将刷毛植在塑胶滚刷轴上，滚刷轴可以做成空心或者实心，以具体结构实施来选择。滚刷均匀布置6-8组刷毛。
滚刷周可以由电机驱动：滚刷轴通过联轴器与第三驱动电机连接。实现滚刷的转动。
滚刷与滚筒的结构布置可以是多种形式，主要以实现上述功能为主。
滚刷组件可以用到本公开中所提及的所有类型的清洁工具中。
直排刷固定在清洁头的壳体上。
直排刷可以用到本公开中所提及的所有类型的清洁工具中。
在针对黏性垃圾场合比较多的情况下，如果使用滚动的毛刷或者直排毛刷来清洁滚筒时，黏性物体会粘在毛刷上面，最后清理机器会比较困难。为此，本公开采用刮条、刮板结构能够将滚筒上面的黏性湿垃圾刮到垃圾箱内，具体实施方案如图9所示，清理单元为刮条组件133。
如结合图3和图9所示，刮条组件133包括长条状的刮条支架133c，用于固定在清洁头上。在刮条支架133c上设置有大致呈“人”字形的摩擦部133a和引流部133b。为了方便理解，在图23的坐标中，将X向称为长度方向，将大致Y向称为宽向，将大致Z向称为高向。
刮条组件133由所述刮条支架向宽向延伸形成。引流部133b位于所述刮条支架的两端，大致沿述刮条支架的高向延伸。
在图9所示清洁工具中，清洁工具包括滚筒111、以及驱动滚筒的电机113a、铲条112、垃圾盒141。
其中滚筒外层由吸水海绵层，内层由硬胶支撑，硬胶两端或者中心设置驱动力可以使滚筒旋转。
其中垃圾盒141上方贴紧滚筒111的位置固定有刮条支架133c。刮条组件133与滚筒111紧密接触，摩擦部的端头干涉滚筒表面0-0.5mm。摩擦部133a可以将残留在滚筒111上的浮灰、黏性垃圾与滚筒剥离，使其掉到垃圾盒141中。引流部133b与滚筒111贴合，向滚筒中心预压0.5-3mm左右，由于清洗滚筒的水槽设计在上方，引流部133b的作用是用来封水，防止水槽 中的水从刮条的两端流到垃圾盒中。
刮条组件可以用到本公开中所提及的所有类型的清洁工具中。
在图13所示的清洁工具中，还包括污水箱211和净水箱231。净水箱231设置拖把杆40接近拖把头的一端。净水箱包括长条形排列的净水出口2311，净水出口在挤压辊121和刮条组件133之间对准滚筒111的表面。
另外，在其他实施例中，污水箱可以通过管路连接污水口，污水口设置在壳体侧面的靠近挤压辊和刮条之间的位置。净水箱通过管路连接净水口，净水口设置在另一个侧面的靠近挤压辊和刮条之间的位置，并且，净水口距离地面的高度大于污水口距离地面的高度。刮条组件的引流部恰好位于净水口和污水口处。在此实施例中，利用净水口和污水口的高度差，依赖水的自重促进水流，再有刮条组件的引流部的引导水的作用，可以更好的避免水溢流出水路系统。
手持部的实施例
带有净水箱：
净水供给单元160包括净水箱231。手持部除了上述的清洁杆301、延长杆302、连接结构304、铰接结构305以外，还可以配备有净水箱。
其中一种实施方式如图4所示。净水箱231的净水出口2311朝向挤压辊，净水从挤压辊向下流入挤水区，冲洗滚筒111的表面。
或者，另一种实施方式如图1所示，净水箱231被固定在手持部靠近清洁头的位置，通过水管将净水接入到清洁头内部。
再一种实施方式中，可设置大型的净水箱231。如图14所示。
在中空的清洁杆中还可以设置臭氧发生装置和气泵，为水箱消毒。
也可以在中空的清洁杆中集成助力控制系统，为清洁工具的前进或后退提供助力。
本公开上述各个清洁工具的零部件，可以根据需求组合。下面例举几种组合后的清洁工具的实施例。
清洁工具的实施例
本实施例具有助力系统，适用于体型较大的清洁工具。
图14至18为本实施例结构示意图。如图所示，清洁工具包括底部设有由电机驱动的助力轮组件11的清洁头10、中空的拖把杆40，拖把杆铰接在拖把头上。拖把杆的近地端装配有大容量的净水箱。水箱较重，为了省力，方便操作，拖把杆40包括具有助力识别结构的手柄41。助力识别结构与助力轮组件电机电连接，控制助力轮组件电机22的转向。清洁头包括上述各实施例之一的拖扫单元、挤压单元、清理单元、干垃圾收集单元和污水收集单元，不再赘述。
具有助力识别结构的手柄41包括：控制单元、压力传感器410、传感器顶杆412、顶杆滑套415和手柄套413。压力传感器410安装在拖把杆端面和手柄套413之间。传感器顶杆412一端抵顶压力传感器410，另一端固定在手柄套413内。压力传感器与述控制单元信号连接，控制单元控制所述电机的转向。顶杆滑套415的内径固定在传感器顶杆412的圆周面，一端与拖把杆端面固定，外圆周面滑动套装在手柄套413内。
控制助力的方法为：工作时，压力传感器检测手柄的受力；控制单元根据检测值与之前作用在手柄上的力的大小比较，判断手柄的受力变化：当受力变大了，控制电机正传，并加大转速，助力轮组件朝前加快旋转，清洁工具向前加快前进；当受力变小了，控制电机正转，减小转速，助力轮组件朝前旋转，但转速降低，清洁工具降低速度向前；当受力变为负值，控制电机反转，助力轮组件朝后旋转，清洁工具向后退。
公开还涉及一种实现上述方法的装置，装置至少包括检测模块、判断模块和执行模块。其中检测模块检测手柄的受力，并将结果发送给判断模块。 判断模块接收检测值，将检测值与之前作用在手柄上的力进行大小比较、方向比较，判断出手柄的受力变化，将比较结果发送给执行模块。执行模块根据接收判断模块的判断结果，控制控制电机的旋转方向。
本实施例的助力轮组件11位于清洁头的后部，使得清洁工具重心更稳。助力轮组件11包括：轮子12、驱动轴13、固定罩14、固定罩盖子15；驱动轴13穿过固定罩盖子15和轮子12中心的孔，与电机22的输出轴连接。固定罩14、固定罩盖子15形成空间容纳轮子12。固定罩14和固定罩盖子15之间紧固件固定，再由紧固件固定在清洁头底部的壳体500上。
本实施例在拖把杆的近地端装配有大容量的净水箱。
本公开清洁头包括从前至后排布的污水箱211、挤压辊121、滚筒111、毛刷组件131和干垃圾盒141。各零部件的排布，可以根据本公开的上述内容设置。
本公开利用“水尘环流”清洁技术能够实现滚筒的自清洁，而且将扫、拖、洗、拧结合在一起，极大地方便使用者，且能实现非常好的清洁效果。
以上所述仅为本公开的较佳实施例而已，并不用以限制本公开，凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
最后应说明的是：以上所述仅为本公开的优选实施例而已，并不用于限制本公开，尽管参照前述实施例对本公开进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换。凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
