Description

一种对折挤水式发泡棉拖把 技术领域
本发明涉及一种对折挤水式发泡棉拖把，其中发泡棉可以是胶棉头、海绵头或类似物。
背景技术
目前市场上的发泡棉拖把的挤水方式大致有三种：第一种是手拉挤水式；第二种是拖把头翻转整体挤水式；第三种是对折挤水式。
如专利号为ZL201320468680.0(公告号为CN203379085U)的中国实用新型专利《一种对折挤水拖把》，专利号为ZL201621230208.3(公告号为CN206729843U)的中国实用新型专利《一种对折式胶棉拖把》，专利号为ZL201821938901.5(公告号为CN209611033U)的中国实用新型专利《对折挤水胶棉拖把》，它们均披露了对折挤水式的拖把，其包括拖把杆、对折式拖把头、挤水架、驱动对折式拖把头进入或退出挤水架的驱动结构，现有对折式挤架均为呈U形的叉状，具有两左右间隔设置的挤水臂，对折式拖把头通过驱动结构能进入或退出由挤水臂构成的挤压口内，对折式拖把头在退出挤压口的状态下，对折式拖把头在自身弹簧作用下处于展开的拖地状态，对折式拖把头在进入挤压口的状态下，挤水臂驱动对折式拖把头的折叠板部分向下摆动对折，形成对折以对折叠板底部的擦拭物进行对折挤水。
现有对折挤水拖把存在下述缺陷：1、驱动挤架滑移的结构复杂，一般采用扳手驱动方式或螺纹杆传动方式或齿轮传动方式。2、现有对折式挤水拖把在挤水操作省力和挤水效果之间不能达到较好的平衡。3、现有挤水架只能在对折式拖把头的折叠方向上对擦拭物进行挤水，挤水效果欠佳。4、挤水架与拖把杆之间装配间隙大，两者易相对晃动。5、折叠式拖把头进入挤架后，两挤水臂之间不再对拖把头进行挤压，且挤水架只能在对折式拖把头的折叠方向上对擦拭物进行挤水，挤水效果欠佳。6、有的对折挤水拖把的挤水架与拖把头之间没有连接部件连接，拖把头与拖把杆之间为松动的万向连接，拖把头易晃动，挤水操作不方便。7、现有挤水架呈扁平的U形，胶棉拖把在挤水完成后，无法直立，只能将拖把杆靠在墙面上，并使胶棉头平放至于地面，胶棉头易风干发硬，且易脏。8、现有胶棉拖把在存放时，胶棉头的长度方向与拖把杆的轴向相互垂直，这导致存放胶棉拖把的空间必须很大，不方便存放，而且现有胶棉拖把的包装盒体积大，相同空间放置胶棉拖把少，增加运输成本。
因发泡棉对折后，对折位置的上部受力最大，变形量大，发泡棉会往下集中，导致下部的发泡棉变的很膨大，不利于挤压，或者挤压程度会不够。
确保水份挤干有两个主要指标，第一个指标是有效的挤压，让挤水装置对拖把头的发泡棉形成强力的挤压；第二个指标是有效的排水，被挤压出来的水不能及时排除，当拖把头脱离挤水装置后，水会重新被发泡棉吸收，影响挤干效果，另外因不能及时排水，还会使得操作者移动拖把头通过进入挤水装置时更费力，另外还会导致水的飞溅。
综上所述，现有对折挤水式胶棉拖把还可作进一步改进。
发明内容
本发明所要解决的技术问题是针对上述现有技术现状而提供一种结构简单合理、对折挤水效果好的对折挤水式发泡棉拖把。
本发明解决上述技术问题所采用的技术方案为：一种对折挤水式发泡棉拖把，包括拖把杆、具有发泡棉的对折式拖把头、挤水架，所述对折式拖把头活动连接在拖把杆的下端；所述对折式拖把头包括中部板体及两个折叠板，所述中部板体活动连接在拖把杆下端，两折叠板分别铰接在中部板体相对的两侧，折叠板与中部板体之间设有使折叠板保持展开位置状态的复位弹性件，发泡棉连接在所述折叠板的底面；其特征在于：所述挤水架设于拖把杆上并可上下滑移的，所述挤水架具有开口朝下呈环状的挤压腔，挤压腔内设有两个能对折叠板的顶面形成滚动挤压的挤压辊；在挤水架处于上移位置，对折式拖把头脱离挤压腔，对折式拖把头处于展开的拖地状态；在挤水架下移过程中，挤水架的下部先与折叠板的顶面接触，先促使折叠板摆动进行预先对折挤水，对折式拖把头部分进入挤压腔后，再通过所述挤压辊与折叠板的顶面接触，对折叠板形成挤压进行进一步的挤水。
进一步改进，上述挤水架的下部与折叠板的转动轴线之间的第一挤压力臂大于挤压辊的轴线与折叠板的转动轴线之间的第二挤压力臂。该设置能使挤水架的下部更为轻松触动折叠板摆动，预先对折挤水所受阻力小，操作轻松，另外挤压辊与折叠板的转动轴线之间的第二挤压力臂小，能更好对折叠板施加挤压力，挤水效果好。
为更好对发泡棉进行挤压，进一步改进，上述挤压腔内还设有两个辅助挤压辊，辅助挤压辊前后间隔设置用以对侧凸出折叠板的对折后的发泡棉侧部进行挤压。对折式拖把头对折后，发泡棉会侧凸出折叠板，辅助挤压辊会对这部分发泡棉进行挤压，更充分挤掉发泡棉内的水份。
作为优选，上述辅助挤压辊设于所述挤压辊的下方。对折式拖把头完全进入挤压腔内后，挤压辊始终与折叠板的背面接触，否则对折式拖把头就不易向下脱离挤压腔，此时若辅助挤压辊设于所述挤压辊的上方，那么会导致位于挤压辊下方的发泡棉不能被所述辅助挤压辊挤压，影响辅助挤压辊的挤水效果。
更进一步改进，上述挤压腔内安装有安装支架，所述挤压辊及辅助挤压辊均设置在该安装支架上。这样可以预先将各挤压辊和辅助挤压辊安装到安装支架上，然后再加安装支架组装到挤压腔内，实现模块化组装，组装方便。
因挤压辊和辅助挤压辊上下位置不同，且作用不同，为防止挤压辊和辅助挤压辊安装错位，作为优选，上述安装支架的相对两个外端面与挤压腔的相对两个内壁之间设有筋槽限位结构，所述筋槽限位结构中的槽设于安装支架的外端面或挤压腔的内壁的其中之一上，所述筋槽限位结构中的筋设于安装支架的外端面或挤压腔的内壁的其中另一上。筋槽限位结构有安装指示作用，避免错误安装。
作为优选，上述安装支架上设有多个弹性卡脚，所述挤压腔的内壁上设有与所述弹性卡脚匹配的卡槽。卡扣的方式具有安装方便的优点。
作为改进，上述挤水架与拖把杆之间设有定位结构，该定位结构能将挤水架定位在上移位置状态，定位结构解除定位后所述挤水架能沿拖把杆上下滑移。定位结构能将挤水架定位在上部位置，不轻易下移，不会对拖地产生影响，定位解除后便可以移动挤水架实现对对折式拖把头的挤水。
进一步改进，上述挤水架内还安装有限位架，所述挤水架内的上部设有供拖把杆穿过的通道，通道位于挤压腔的上方并相互连通，限位架位于通道和挤压腔之间，限位架上开有与拖把杆外形匹配的限位通道，该限位通道与所述通道一起形成对拖把杆的限位。限位架起到进一步定位拖把杆作用，避免拖把杆相对挤水架晃动厉害。
作为优选，上述定位结构包括固定在拖把杆上的定位块及设置在限位架上的限位件，限位件上设有弹性卡槽，弹性卡槽的开口朝上且弹性卡槽的口径上小下大，在挤水架受力上移过程中，所述定位块经由弹性卡槽的小口径部卡入弹性卡槽的大口径部位内完成定位，在挤水架受力下移过程中，所述定位块经由弹性卡槽的小口径部脱离弹性卡槽完成解锁。该定位结构涉及部件少，利于组装，且定位的解除也较轻松。
进一步改进，上述限位架上设有位于弹性卡槽上方并连通的第一导向槽，所述通道内壁上开有与所述第一导向槽衔接导通的第二导向槽，所述定位块能沿所述导向槽上下滑移，定位块与导向槽的配合能阻止挤水架绕拖把杆轴线旋转。本导向结构充分利用定位块这一部件，无需额外设置导向块，结构简单。当然也可采用现有其它导向结构。
更进一步改进，上述中部板体上设有供拖把杆的下端活动连接的接头部，拖把杆内设有由弹性件作用保持下移趋势的施力部件，该施力部件对所述接头部中部施加向下的压力、以使挤水架在上移和下移过程施力部件对所述接头部同一位置施加压力。其改变现有折叠挤水拖把中拖把杆与拖把头之间松动连接的方式，施力部件对接头部力的施加的力使中部板体保持相同平衡状态，施力的方向一致，在拖把头挤水过程中还未接触到折叠板过程中，拖把头也不轻易晃动，保证两侧的折叠板受力均衡，挤水效果好。
为使接头部与施力部件之间有一定的左右限位作用，上述接头部的顶壁设有内凹的定位凹槽，所述施力部件的底面外形与定位凹槽匹配。定位凹槽的左右内壁对接头部有约束作用，使施力部件不能轻易脱离接头部。作为优选，上述定位凹槽的左右内壁为自下而上向外倾斜的第一斜面，所述施力部件的左右两侧壁具有与所述第一斜面配合的第二斜面。斜面的设置在使接头部与施力部件之间具有一定左右限位作用的同时，又不会使施力部件脱离接头部的阻力太大。
进一步改进，上述拖把杆的下端连接有衔接件，所述衔接件与所述接头部铰接且仅能左右摆动，所述弹性件及施力部件安装在衔接件内。衔接件的设置利于组装。
更进一步改进，上述挤压腔的周壁基本封闭，在挤水架下移至极限位置时，能保证对折后的对折式拖把头全部藏于所述挤压腔内。挤压腔的周壁基本封闭，基本封闭是指挤压腔的周壁不与外界连通(周壁上没有孔)，当然不是绝对的不与外界连通(周壁上可能有细小的孔)，对折后的对折式拖把头全部藏于挤压腔内，该状态下保持的发泡棉水份流失少，具有良好保湿效果，利于下次拖把头脱离挤压腔，同时无需打湿还可再次使用。
进一步改进，上述挤水架的底面至少具有三个接触部，三个接触部不在同一直线上，对折挤水状态下的对折式拖把头底面位于所述接触部的上方，三个所述接触部均能接触地面而将拖把直立放置。发泡棉不会因为再次接触到底面变脏，对折式拖把头不再横向设置，减少存放时占用的空间，同时也能减少运输时的包装盒体积，利于运输。
作为选择，上述接触部与地面之间为点接触、线接触或面接触。接触部可以是支撑点。线接触与点接触相比稳定性更好。面接触与线接触相比稳定性更好，例如挤水架的环形底面均作为接触位置。
更进一步改进，上述中部板体上设有供拖把杆活动连接的接头部，所述折叠板在长度方向上存在厚度差，靠近中部板体的折叠板部分的第一厚度小于远离中部板体的折叠板部分的第二厚度。这样对折后的拖把头进入挤水架后，拖把头越往上移，对折后的拖把头下端受到挤压力更大，发泡棉变形量也更大，整个发泡棉受压更均衡，挤水效果佳。
作为优选，上述折叠板的顶面为沿长度方向由内向外逐渐向上倾斜的斜面，该斜面形成所述厚度差。挤水时，挤水部件顺沿斜面滑移，让折叠板厚度大的那一端向内折叠程度更大，对折后的拖把头越往上移，对折后的拖把头下端受到挤压力更大，整个发泡棉手压更均衡，挤水效果佳。
作为优选，上述折叠板的内端具有两前后间隔设置的连接部，中部板体设有供连接部插入的插槽及位于两插槽之间的中部槽，所述连接部插入插槽内，有销轴穿过连接部、中部槽、另一侧的连接部后将折叠板安装在中部板体上，所述复位弹性件为扭簧套设在位于中部槽的销轴上。
与现有技术相比，本发明的优点在于：本结构通过挤水架相对拖把杆的上下滑移，促使对折式拖把头折叠后进入挤压腔，完成挤水，无需额外设置驱动结构，结构更简单合理，成本低；挤压辊与折叠板形成滚动摩擦，利于折叠后的拖把头在挤压腔内上移，挤水操作省力；另外挤压辊内凸于挤压腔的端口，挤水时，挤水架的下部促使折叠板摆动进行预先对折挤水，对折式拖把头部分进入挤压腔后，再通过所述挤压辊与折叠板的顶面接触，挤压辊促使折叠板摆动进行进一步的挤水，挤水效果更佳。

具体实施方式
以下结合附图实施例对本发明作进一步详细描述。
如图1～14所示，为本发明的优选实施例。
一种对折挤水式发泡棉拖把，包括拖把杆1、具有发泡棉4的对折式拖把头2、挤水架3，发泡棉可以是胶棉、海绵及其类似物。对折式拖把头2活动连接在拖把杆1的下端。
对折式拖把头2包括中部板体21及两个折叠板22，中部板体21活动连接在拖把杆1下端，两所述折叠板22分别铰接在中部板体21相对的两侧，折叠板22与中部板体21之间设有使折叠板22保持展开位置状态的复位弹性件23，所述发泡棉4连接在所述折叠板22的底面。中部板体21的设置使得发泡棉4中部位置的变形空间大，对折时所受阻力小，另外中部板体21的设置，可使两折叠板21向内翻折的角度更大，对折挤水效果更佳。
中部板体21上设有供拖把杆1的下端活动连接的接头部211，拖把杆1内设有由弹性件10作用保持下移趋势的施力部件11，该施力部件11对接头部211中部施加向下的压力、以使挤水架3在上移和下移过程施力部件11对接头部211同一位置施加压力。
接头部211的顶壁设有内凹的定位凹槽212，施力部件11的底面外形与定位凹槽212匹配，定位凹槽212的左右内壁为自下而上向外倾斜的第一斜面2121，施力部件11的左右两侧壁具有与第一斜面2121配合的第二斜面111。
拖把杆1的下端连接有衔接件12，衔接件12与接头部211铰接且仅能左右摆动，弹性件10及施力部件11安装在衔接件12内。衔接件12具有扁口的插槽121，接头部211插配并通过转轴122转动连接在插槽121内，
挤水架3的底面至少具有三个接触部P，三个接触部P不在同一直线上，对折挤水状态下的对折式拖把头2底面位于所述接触部P的上方，三个所述接触部P均能接触地面而将拖把直立放置。接触部P与地面之间可以为点接触，可以为线接触，还可以为面接触，优选面接触。
挤水架3设于拖把杆1上并可上下滑移的，所述挤水架3具有开口朝下呈环状的挤压腔31，所述挤压腔31内设有两个能对折叠板22的顶面形成滚动挤压的挤压辊7；在挤水架3处于上移位置，对折式拖把头2脱离挤压腔31，对折式拖把头2处于展开的拖地状态。
在挤水架3下移过程中，挤水架3的下部X先与折叠板22的顶面接触，促使折叠板22摆动进行预先对折挤水，对折式拖把头2部分进入挤压腔31后，再通过所述挤压辊7与折叠板22的顶面接触，对折叠板22形成挤压进行进一步的挤水。
挤水架3的下部X与折叠板22的转动轴线之间的第一挤压力臂L1大于挤压辊7的轴线与折叠板22的转动轴线之间的第二挤压力臂L2。挤压腔31内还设有两个辅助挤压辊8，辅助挤压辊8前后间隔相对设置用以对侧凸出折叠板22的对折后的发泡棉4的侧部41进行挤压。辅助挤压辊8设于所述挤压辊7的下方。
挤压腔31的周壁基本封闭，在挤水架3下移至极限位置时，能保证对折后的对折式拖把头2全部藏于挤压腔31内。
挤压腔31内安装有安装支架9，所述挤压辊7及辅助挤压辊8均设置在该安装支架9上。安装支架9上设有多个弹性卡脚91，所述挤压腔31的内壁上设有与所述弹性卡脚91匹配的卡槽311。
安装支架9的相对两个外端面与挤压腔31的相对两个内壁之间设有筋槽限位结构，所述筋槽限位结构中的槽92设于安装支架9的外端面上，所述筋槽限位结构中的筋32 设于挤压腔31的内壁上。
挤水架3内还安装有限位架33，挤水架3内的上部设有供拖把杆1穿过的通道32，通道32位于挤压腔31的上方并相互连通，限位架33位于通道32和挤压腔31之间，限位架33上开有与拖把杆1外形匹配的限位通道331，该限位通道331与通道32一起形成对拖把杆1的限位。限位架33与拖把杆1之间设有定位结构，该定位结构能将挤水架定位在上移位置状态，定位结构解除定位后所述挤水架3能沿拖把杆1上下滑移。
定位结构包括固定在拖把杆1上的定位块5及设置在限位架33上限位件6a，限位件6a上设有弹性卡槽6，定位块5的横截面呈圆形，弹性卡槽6的开口朝上且弹性卡槽6的口径上小下大，在挤水架3受力上移过程中，定位块5经由弹性卡槽6的小口径部61卡入弹性卡槽6的大口径部62位内完成定位，在挤水架3受力下移过程中，所述定位块5经由弹性卡槽6的小口径部61脱离弹性卡槽6完成解锁。限位架33上设有位于弹性卡槽6上方并连通的第一导向槽332，所述通道32内壁上开有与第一导向槽332衔接导通的第二导向槽321，定位块5能沿所述导向槽上下滑移，定位块5与导向槽的配合能阻止挤水架3绕拖把杆1轴线旋转。
中部板体21上设有供拖把杆3活动连接的接头部211，折叠板22在长度方向上存在厚度差，靠近中部板体21的折叠板22部分的第一厚度D1小于远离中部板体21的折叠板22部分的第二厚度D2。
折叠板22的顶面为沿长度方向由内向外逐渐向上倾斜的斜面S，该斜面S形成厚度差。折叠板22的内端具有两前后间隔设置的连接部221，中部板体21设有供连接部221插入的插槽211及位于两插槽211之间的中部槽212，连接部221插入插槽内，有销轴6穿过连接部221、中部槽212、另一侧的连接部221后将折叠板22安装在中部板体21上，复位弹性件23为扭簧套设在位于中部槽212的销轴6上。
各折叠板22的内部设有与外界相通的排水流道X，在擦拭物4受挤水装置挤压状态下，擦拭物4内的水份从擦拭物4的背面经由排水流道X排出外界。具体的，折叠板22的内部设有排水通道222，折叠板22的侧端面上开有连通排水通道222与外界的排水孔223连通，排水孔223与排水通道222一起构成排水流道X，在折叠板22对折挤水状态下，排水孔223朝下。
本实施例中的上下方向指的是顺沿拖把杆1的长度方向；左右方向指的是对折式拖把头2的长度方向。
本实施例的工作原理及过程如下：
挤水操作：一手握住挤水架3，另一手握住拖把杆1，推动挤水架3相对拖把杆1下移，定位块5经由弹性卡槽6的小口径部61脱离弹性卡槽6完成解锁，挤压腔31的下部触动折叠板22顶面继续下移带动两块折叠板22对折，挤压腔31的下部X促使折叠板22摆动进行预先对折挤水，如图6、7所示；对折式拖把头2部分进入挤压腔31后，再通过挤压辊7与折叠板22的顶面接触，促使折叠板22摆动进行进一步的挤水，如图8、9所示。同时，辅助挤压辊8对侧凸出折叠板22的对折后的发泡棉4的侧部41进行挤压。
拖地操作：一手握住挤水架3，另一手握住拖把杆1，上拉挤水架3相对拖把杆1上移至高位，直至对折式拖把头2完全脱离挤水架3，定位块5经由弹性卡槽6的小口径部61卡入弹性卡槽6的大口径部62位内完成定位，此时挤水把手31位于高位，因 拖地时发泡棉头2完全脱离挤压腔31，而发泡棉头2可活动的连接在拖把杆1下端，故发泡棉头2在拖地使用过程中可偏转，操作更舒适合理。
如图12～14所示，折叠板2在长度方向上存在厚度差，靠近中部板体21的折叠板22部分的第一厚度D1小于远离中部板体的折叠板部分的第二厚度D2，这样对折后的拖把头进入挤水架3后，拖把头越往上移，对折后的拖把头下端受到挤压部件5的挤压力更大，整个发泡棉受压更均衡，挤水效果佳。挤水后，发泡棉4内的水份从发泡棉4的背面经由排水通道222和排水孔223后快速向下排出外界，进而提升挤水效果，并使得挤干操作更省力，同时减少水份从擦拭物的周缘排出的量，减少飞溅。
