Description

挤压口可调的挤压平板拖清洁工具 技术领域
本发明涉及清洁工具的技术领域，尤其涉及一种挤压口可调的挤压平板拖清洁工具。
背景技术
挤压平板拖清洁工具的一般结构是：其包括拖把桶和平板拖把，平板拖把包括拖把杆和活动连接在拖把杆上的平板拖把板，平板拖把板上设有擦拭物；拖把桶上安装有挤压口挤压装置，清洗和挤水时将平板拖把板旋转至可进行清洗和挤水的状态；平板拖把板在与挤压口挤压装置之间相对移动挤压从而对擦拭物进行移动挤压清洗和挤水。
挤压平板拖清洁工具有两种，一种是单桶挤压平板清洁工具，另一种是双桶挤压平板清洁工具。单桶挤压平板清洁工具是指只有一个拖把桶，其在拖把桶上设置挤压口挤压装置；双桶挤压平板清洁工具是指拖把桶具有互不联通的清洗区和脱水区，在清洗区和脱水区均设挤压口挤压装置。
为了达到较好的拖地效果、提高拖地效率，通常希望平板拖把板的长度较长，然而在现有的挤压平板拖清洁工具中，平板拖把板整体采用硬质板体，在进行挤水和清洗时插入挤压口挤压装置中挤压时，若平板拖把板长度较长，则对应的拖把桶的高度就较高，从而造成拖把桶体积庞大、不便包装运输等问题。
为了克服上述技术问题，中国专利CN206080446U(专利号为201620870001.6)公开了一种挤压平板拖把清洁工具，其拖把桶具有清洗区和挤水区，其在拖把桶上设置捋口挤压装置，平板拖把的拖把头转动至挤水或清洗状态后，在捋口挤压装置中上下移动，平板拖把头上的擦拭物与捋口挤压装置之间产生挤压作用从而对擦拭物进行挤水或清洗，挤出来的水可通过水路通道流至清洗区。
上述专利还存在的缺点在于；捋口挤压装置中挤压器安装方式无法实现挤压口大小的变化，在向上提起平板拖把时由于挤压器和擦拭物之间的摩擦作用可能会将拖把桶提起，在向下压平板拖把时又无法获得稳定而适当的挤压力。

具体实施方式
下面结合附图和具体实施方式对本发明作进一步详细说明。
如图1-图5所示，为本发明的挤压口可调的挤压平板拖清洁工具的一个优选实施例。该挤压平板拖清洁工具包括拖把桶1、平板拖把2、设置在拖把桶1上的两个挤压装置S。
其中，所述平板拖把2包括拖把杆3和活动连接在拖把杆3上的平板拖把头4，平板拖把头4上设有擦拭物5，擦拭物5用来擦拭和清洁物体，可以采用现有的各种材料，比如毛巾、绒布等织物，擦拭物5大致呈片状，其贴合在平板拖把头4的其中一个表面而构成单面平板拖把，或者在平板拖把头4的两个表面分别设置一块擦拭物5而构成双面平板拖把，这些都属于现有技术这里不再详述。
所述的拖把桶1具有独立的挤水区6和独立的清洗区7，所谓独立的挤水区6和独立的清洗区7是指：拖把桶1具有两个互不连通的容积体，其中一个容积体作为挤水区6，另一个容积体作为清洗区7。在本实施例中，两个挤压装置S分别设置在挤水区6、清洗区7的顶部位置，当需要清洗擦拭物5或对擦拭物5进行挤水时，可将所述的平板拖把头4旋转至靠近拖把杆3的一侧的状态，如图1-图5所示，平板拖把头4以及擦拭物5可插入到挤压装置S中、并相对挤压装置S上下移动而进行清洗或挤水。工作时， 清洗区7内一般需要较多的水，而挤水区6处于基本无水的状态，或只有少量的水，从而避免水又复吸入进行挤水操作中的擦拭物5内。
所述的挤压装置S包括用于对平板拖把头4上的擦拭物5进行挤压的刮板8、与所述的刮板8相对的支撑件，所述的刮板8与支撑件之间形成供平板拖把头4连同擦拭物5插入的挤压口9。
所述的支撑件为另一块刮板或其他支撑部件。当支撑件为另一块刮板时适用于双面平板拖把的情形，即平板拖把头4的两面均设置擦拭物5；当支撑件为其他支撑部件时适用于单面平板拖把，即平板拖把头4的其中一面设置擦拭物。
挤水时，所述的平板拖把头4连同擦拭物5插入位于挤水区6的挤压装置S的挤压口9中，所述的擦拭物5与所述的刮板8之间相对移动挤压从而对擦拭物5进行挤水；清洗时，所述的平板拖把头4连同擦拭物5插入位于清洗区7的挤压装置S的挤压口9中，所述的擦拭物5与所述的刮板9之间相对移动挤压从而对擦拭物5进行清洗。
所述的刮板8可相对拖把桶1转动，所述刮板8的转动可改变所述挤压口9的大小；具体地，下压平板拖把头4时(平板拖把头4相对挤压装置S向下移动)，所述的刮板8向下转动，刮板8相对于所述的支撑件处于窄位位置，从而使挤压口9相对较小，上拉平板拖把头4时(平板拖把头4相对挤压装置S向上移动)，所述的擦拭物5带动所述的刮板8向上转动，从而使所述的挤压口9变大。
所述的刮板8可以直接安装在所述的拖把桶1上(如图32所示的第十三种挤压装置)。所述的刮板8也可以先安装在一挤压架10上，所述的挤压架10再安装到所述的拖把桶1上。
下面以刮板8安装在挤压架10上为例对本发明实施例进行进一步的展开说明。该挤压架10具有开口，刮板8可转动的安装在挤压架10上，开口中与刮板8相对的那一侧设有支撑部件，刮板8的侧边露在开口内从而可刮擦到插入其中的擦拭物5，刮板8与支撑部件之间形成挤压口9，此时平板拖把为单面平板拖把，即平板拖把头的一面设有擦拭物，所述的平板拖把头4旋转至清洗和挤水状态时，所述的平板拖把头4位于所述拖把杆3的一侧；或者与刮板8相对的开口的另一侧设有另一块刮板，刮板与刮板之间形成挤压口9，此时平板拖把为双面平板拖把，即平板拖把头的两面均设置擦拭物。挤压架10开口的形状不受限制，可以是如图1-24所示的狭长的条状孔，也可以如图25所示是三角形、如图26所示是半圆形等。
本发明的支撑部件可采用如下几种形式：最简单地方式是，支撑部件由挤压架10的开口中与刮板8相对的那一侧的侧壁直接形成(即，第一种支撑部件为光滑的平面)；
这里详细介绍三种较为优选的支撑部件，第一种支撑部件如图22所示，是在挤压架10的开口中与刮板8相对那一侧设置一对轮子11，图8-图21示出的七种不同的挤压装置S中的支撑部件均采用这种方式；
第二种支撑部件如图23所示，是在挤压架10的开口中与刮板8相对的那一侧设置多个支撑导向筋12；当然，也可以是轮子11和支撑导向筋12的组合设置；
第三种支撑部件如图24所示，是在挤压架10的开口中与刮板8相对的那一侧设置一对弹性块50，各弹性块50的尾端与挤压架10之间有弹簧51，从而将弹性块50抵住并外露于挤压口9。
清洗和挤水时所述的支撑部件顶在所述平板拖把头4的未设擦拭物一面，支撑部件对平板拖把头4起到引导和支撑的作用，防止其在上下移动过程中发生翻转，需要说明的是，在平板拖把头4的上下移动过程中，支撑部件并不一定全程与平板拖把头接触。优选的结构是所述的支撑导向筋12延伸至所述开口的下部，则该支撑导向筋12具有较长的长度，即使平板拖拉把头4插入的位置较深，也可通过该支撑导向筋12对平板拖把头4形成阻挡限位，防止其脱离挤压装置。作为一种比较好的结构形式，所述支撑导向筋12的下端设为弧形面或斜面，当平板拖把头插入极深时可通过该弧形面或斜面引导平板拖把头4向上回拉。
本实施例中，与挤水区对应的拖把桶的顶部安装有挤压装置、与清洗区对应的拖把桶的独有安装有一挤压装置，当然，拖把桶也可以仅安装一个挤压装置S，这种情况下，挤水时挤压装置在挤水区中，清洗时挤压装置在清洗区中，具体地，挤压装置可滑动或可翻转的设在拖把桶上，从而实现挤压装置在挤水区和清洗区之间的位置转换。
平板拖把在挤水时，平板拖把头4旋转至可进行挤水的状态(这种状态通常体现为平板拖把头旋转后与拖把杆平行或基本平行)，然后将平板拖把插入到挤压口9中上下移动，平板拖把头上的擦拭物5与刮板8之间相对移动挤压，从而进行挤水。
平板拖把在清洗时，清洗区内盛水，平板拖把头4旋转至可进行清洗的状态(这种状态通常体现为平板拖把头旋转后与拖把杆平行或基本平行)，然后将平板拖把插入到挤压口9中上下移动，平板拖把头4上的擦拭物5与挤压装置S的刮板8之间相对移动挤压刮擦，从而进行清洗。
图8-图21示出了七种不同的挤压装置S，其不同点在于刮板8与挤压架10之间的连接结构和限位装置。具体描述如下。
所述的刮板8可直接转动连接在挤压架10上，具体地，图8、图9所示的第一种挤压装置和如图16、图17所示的第五种挤压装置，所述刮板8的两头转动连接在所述的挤压架10上：所述刮板8的两头均设有转动销13，两转动销13分别插入挤压架10上的轴孔14中。或者，如图10、图11所示的第二种挤压装置和如图18、图19所示的第六种挤压装置，所述的挤压架10上设有凸轴15，所述刮板的两头设有插孔16，所述的凸轴15分别插入到所述刮板两头的插孔16中。
当然，刮板8与挤压架10之间的连接方式还可以采用其他结构形式，只要达到刮 板8与挤压架10之间活动连接从而使刮板可转动，该刮板8在转动的过程中可调节挤压口9的宽度大小的效果即可。下面列举中上实现上述效果的具体连接结构：
①如图12、13所示的第三种挤压装置，所述的挤压架10上设有枢接座17，所述刮板8的侧边枢接在所述的枢接座17上。
②如图14、15所示的第四种挤压装置，所述挤压架10上设有卡座18，该卡座上设有卡口19，所述的刮板8上设有卡轴20，所述的卡轴20卡入卡座的卡口19内后转动。
对所述刮板8的转动进行限位而使其能限位在窄位位置可采用如下方式来实现：所述的挤压架10上设置有一限位装置，该限位装置能将刮板8限定在所述窄位位置，由该限位装置来确定具体的窄位位置所在，该限位装置还可将刮板8限定在挤压口变大时的最大挤压口位置。如图8、9、10、11、12、13、14、15所示的这四种挤压装置中，其限位装置为一行设于挤压架10上的限位座21，限位座可以直接设在挤压架21上，也可以设置在枢接座17上，限位座21上开设有限位凹口22，所述的刮板8位于限位凹口22中，所述的刮板8与所述限位座21一侧触碰时达到窄位位置、与限位座21的另一侧触碰时达到最大挤压口位置。还可以在刮板8上设置凸耳23来辅助限位，通过凸耳23与限制座的触碰来达到最大挤压口位置。
当然，限位装置还可以采用其他结构形式，例如如图17所示的第五种挤压装置，在刮板8的两头设置向外凸出的限位块24，在挤压架10上设置限位口25，限位块24插入限位口25中，限位块24在限位口25内活动，所述的刮板8与所述限位口25一侧触碰时达到窄位位置、与限位口25的另一侧触碰时达到最大挤压口位置，又如图19所示的第六种挤压装置，限位装置为设于挤压架10上的限位凹槽26，所述刮板8的两头分别插入所述的限位凹槽26中，刮板8与限位凹槽26一侧触碰时达到窄位位置、与限位凹槽26的另一侧触碰时达到最大挤压口位置。限位装置还可以是在挤压架10上设有对刮板8形成阻挡的两个阻挡部分，阻挡部分形成所述的限位装置，当刮板与一个阻挡部分触碰时达到窄位位置、与另一个阻挡部分触碰时达到最大挤压口位置。
当平板拖把头4插入挤压口9中相对挤压装置S向下移动时，擦拭物5与刮板8之间接触，擦拭物5在摩擦力作用下带动刮板8向下转动，从而使得挤压口9变窄并达到窄位位置，保持挤压口9开口较小状态，利于将擦拭物5挤干；当平板拖把头4向上运动时，擦拭物5与刮板8之间接触，在摩擦力作用下刮板8向上转动，从而使得挤压口9变宽并到达最大挤压口位置，保持挤压口9开口较大状态，刮板8与擦拭物5之间的摩擦力减小，从而减小擦拭物5的磨损，同时使平板拖把2向上提时不会将拖把桶1也拎起来。
如图20、图21所示的第七种挤压装置，刮板8和挤压架10之间的活动连接结构自然地形成有限位装置，具体地；所述的挤压架10上设有与刮板8两头对应的斜凹槽27，所述刮板8的两头插入所述的斜凹槽27中，且所述的刮板8与所述的斜凹槽27之间具 有沿刮板厚度方向的活动空间，来回移动平板拖把头，擦拭物5与刮板8之间接触，带动刮板8在斜凹槽27中翻动，从而便刮板8具有一定的转动角度，达到调节所述挤压口的开口大小的效果。且由于斜凹槽27的限制，刮板8只能在一定程度内活动，从而可达到窄位位置和最大挤压口位置。
或者，所述刮板的两头设有斜凹槽，所述的挤压架上设有与两斜凹槽对应的插板，所述的插板插入所述的斜凹槽中，且所述的插板与所述的斜凹槽之间具有沿刮板厚度方向的活动空间，推拉挤水手把，擦拭物与刮板之间接触，带动刮板翻动，从而使刮板具有一定的转动角度，达到调节所述挤压口的开口大小的效果。且由于斜凹槽与插板的配合限制，刮板只能在一定程度内活动，从而可达到窄位位置和最大挤压口位置。
在前面的具体实施方式中，刮板到达窄位位置是通过擦拭物5自然地带动刮板8转动来实现的。刮板8达到窄位位置还可以采用其他方式来实现，例如图6、图7分别示出了在挤压架10中设置两种不同形式的弹性装置的方式，弹性装置作用于所述的刮板8使其处于窄位位置从而使挤压口较小，在这种情况下，刮板8初始状态下即位于窄位位置，而不需要下压的平板拖把头4而使擦拭物5来带动刮板8转动至窄位位置。当向上拉动平板拖把头4时，擦拭物5与刮板8之间的摩擦挤压力克服弹性装置的弹性力，从而使刮板8向上转动，从而使挤压口变大。这种方式同样能实现高效的挤水效果，向上拉动平板拖把的操作也十分轻松。第一种弹性装置的具体结构，如图6所示，该弹性装置为限位在挤压架10中的压簧28，压簧28的一端与挤压架10相抵、另一端与刮板8延伸出的抵触端81相抵，从而使得刮板8具有向窄位位置转动的趋势。第二种弹性装置的具体结构，如图7所示，该弹性装置为限位在挤压架10中的扭簧29，扭簧29的一端与挤压架10相抵、另一端与刮板8延伸出的凸耳23相抵，从而使得刮板8具有向窄位位置转动的趋势。
本实施例中，在挤压架10开口外围设有用于引导平板拖把头4插入的引导面30，在平板拖把头4插入到挤压口9中时，通过引导面30的引导可更方便的将平板拖把头4插入。引导面30通常设置为向下倾斜的斜面，引导面30的另外一个作用：在挤水时挤出来的水由于该引导面30的作用不会洒出拖把桶1外，参见图1。
在前述的七种挤压装置S中，刮板8安装在挤压架10上，且挤压架10上设有开口。图27-图31示出了第八种-第十二种挤压装置，其挤压架10不具有开口，挤压装置S的挤压架10仅提供刮板8的安装，刮板8安装在挤压架10上，同时，拖把桶1的内壁上设有支撑件，支撑件与刮板8相对设置，从而在刮板8与支撑件之间形成挤压口9。
如图27所示的第八种挤压装置，支撑件是支撑板31，该支撑板31设在与刮板相对的拖把桶1的端面上；如图28所示的第九种挤压装置，支撑件是支撑板31’，该支撑板31’设在拖把桶1的侧面并横向延伸；如图29所示的第十种挤压装置，支撑件是设在与 刮板8相对的拖把桶1的端面上支撑架32，支撑架32的末端设有滚轮33；如图30所示的第十一种挤压装置，支撑件是设在拖把桶1的侧面上支撑架32，支撑架的末端设有滚轮33；如图31所示的第十二种挤压装置，支撑件是设在拖把桶1的侧面上的横向延伸的导向板34，平板拖把头4的两侧设置导向槽，进行清洗或挤水时导向板34插入导向槽中。
如图32所示的第十三种挤压装置，挤压装置S不包含挤压架，刮板8直接安装在所述的拖把桶1上，具体地，刮板8的两端设置轴柱82，轴柱82直接穿入拖把桶1中，或者采用与前面实施例所述的转动连接相同的转动连接方式，不同的是转动连接结构设在拖把桶上。此时平板拖把头4下压时刮板8相对于支撑件处于窄位位置以及刮板8位于最大挤压口的位置的实现，也可通过限位装置来实现，限位装置的具体结构方式可参照前面实施例的描述，不同之处在于：前述的第一种-第七种挤压装置中限位装置是安装在挤压架10上，而如图32所示的第十三种挤压装置中，限位装置是安装在拖把桶1上的。需要说明的是，图27-图32所示的拖把桶上仅画出挤水区6设置有挤压装置S的情况，而清洗区7中挤压装置的具体设置与挤水区中的挤压装置是相同的即，清洗区中挤压口的实现与挤水区的挤压口9可以是相同的，图中省略。
本实施例中，挤水区和/或清洗区内的拖把桶的底部设有凸起的凸台，所述的凸台向远离刮板8方向延伸且延伸的长度至少超越所述的挤压口9。凸起的凸台的意义在于：将平板拖把头4插入到挤压装置中时，要防止平板拖把头4插入过多，导致平板拖把头4越过挤压口9，此时平板拖把头落至挤压装置的下方，导致无法顺利将平板拖把头向上回拉。设置凸台后，凸台对平板拖把头4的下压极限位置进行了限定，平板拖把头4碰到凸台后不能再下压，从而避免上述现象的产生。另外，凸起的凸台需要有一个较长的延伸长度，其延伸的长度至少超越所述的挤压口9，防止在平板拖把头4下压过程中因为产生一定长度的倾斜从而脱离该凸台的控制。
如图32所示的第十三种挤压装置中，所述的拖把桶内设有隔板36，所述的隔板36将所述的拖把桶分隔成独立的挤水区6和独立的清洗区7。隔板36可与拖把桶一体成型。当然独立的清洗区和独立的挤水区还可以采用其他方式来形成了，例如设置独立的挤水桶，设置独立的清洗桶，然后将挤水桶和清洗桶连接起来。
