Description

一种地面清洁装置的地刷结构 技术领域
本发明涉及地面清洁装置领域，具体是地面清洁装置的地刷结构。
背景技术
地面清洁装置包括地刷以及主机，主机设有抽吸装置及喷水装置的连通地刷，并通过地刷对地面进行洗刷吸尘完成地面清洁工作。地刷上设有滚筒露出在地刷前端，通过高速旋转的滚筒对地面进行擦拭以及将地面上的垃圾卷入滚筒后方由抽吸装置产生的吸力吸入地刷并保存在主机内的垃圾桶内。
由于地面上的垃圾全靠滚筒卷入清理，当垃圾接触高速旋转的滚筒，会被旋转的力所弹开，导致地面上的垃圾无法有效清洁地面上的垃圾，使清洁效果变差。
发明内容
为了克服现有技术的不足，本发明提供一种地面清洁装置的地刷结构。
本发明解决其技术问题所采用的技术方案是：
一种地面清洁装置的地刷结构，包括壳体以及由壳体形成的滚筒腔，壳体内形成有抽吸通道连通所述滚筒腔；所述滚筒腔内安装有自滚动的滚筒，所述壳体底部设有连通滚筒腔的底部敞口，所述滚筒经底部敞口与清洁面接触，所述底部敞口四周边缘设置有密封胶条与地面贴合，在地刷的行进方向上，位于前侧的密封胶条分为多段，且每段密封胶条的端部可形变打开形成吸尘入口。
所述密封胶条包括后侧刮条、左右两侧的边部密封条以及前侧的多段密封片。
所述壳体底部前侧布设有多个安装台，所述密封片固装在安装台上。
多个所述安装台均呈三角形，所述密封片固设在三角形安装台的底边且密封片两端伸出安装台两侧底角，三角形安装台的两斜边朝向前侧形成导向面；吸尘入口形成于两个相邻的三角形安装台的底角。
所述安装台底面朝前侧向上倾斜。
所述密封片呈弧形布设在所述安装台上。
所述壳体前部呈框形结构，框型的壳体前端构成所述滚筒腔，且壳体上方盖合有盖体将所述滚筒腔上方盖合封闭。
所述滚筒腔侧壁设有安装所述滚筒的滚筒安装槽，滚筒端部设有卡装结构通过掀起所述盖体由上自下卡入所述滚筒安装槽内。
所述壳体后部内形成有抽吸通道连通抽吸源，且壳体后部设有滚筒电机以及传动机构的安放腔，滚筒电机通过传动机构传动连接所述滚筒。
所述壳体后端设有与抽吸主机装置铰接的铰接座，且铰接座两侧设有移动轮；所述壳体底部设有辅助轮。
本发明的有益效果是：通过本发明的结构设计，当清洁地面时，滚筒腔底部敞口的四周边缘通过密封胶条与地面贴合，增强对地面的抽吸力度，配合多段密封胶条端部形变打开形成吸尘入口，先将地刷前方的垃圾以及灰尘颗粒吸入底部敞口所形成的闭合空间内，避免被高速旋转的滚筒弹出，再经抽吸通道吸入回收，相较于现有技术中的 结构设计，能更有效将垃圾收集清理吸走，大大提升了地面的清洁效果；同时，在增强负压抽吸力度后，利用自滚动的滚筒提供带动地刷行走的动力，令用户使用更加轻松。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是洗地机的结构示意图；
图2是地刷底部的结构示意图；
图3是地刷的剖视图；
图4、图5是地刷的拆分示意图。
具体实施方式
本发明可以应用在常见的带抽吸功能吸入垃圾的地面清洁装置上，比如：手持洗地机、清洁机器人等。
参照图1的实施例，以一种手持洗地机进行举例说明，其包括主机200以及转动连接在主机200底部的地刷100：
主机200顶部装有手持手柄，主机200上设有抽吸回收装置201并通过管道连通地刷100，地刷100上设有清洁液装置300，包括清洁液罐和水泵，抽吸回收装置201包括抽风电机以及存放吸入污物的垃圾桶。
如图2至图5所示，地刷100包括壳体1以及由壳体1形成的滚筒腔2，壳体1内形成有抽吸通道3使主机200的抽吸装置连通滚筒腔2，对滚筒腔2内进行抽吸形成负压并将脏污抽走；滚筒腔2内安装有滚筒4，壳体1底部设有连通滚筒腔2的底部敞口21，并通过底部敞口21对地面进行抽吸，滚筒4经底部敞口21与清洁面接触，清 洁液装置300为滚筒4提供清洁液使其湿润并通过高速旋转对地面的顽固脏污擦拭干净，同时在滚筒4高速旋转的带动下，使地刷100具有自动向前进的力，进行地面的清洁工作。底部敞口21四周边缘设置有密封胶条5与地面贴合，增强对地面的抽吸力度；根据地刷100的行进方向，位于前侧的密封胶条5分为多段，且每段密封胶条5的端部可形变打开形成吸尘入口，通过吸尘入口先将地刷前方的垃圾以及灰尘颗粒吸入底部敞口21所形成的闭合空间内，避免被高速旋转的滚筒4弹出，再经抽吸通道3吸入回收至抽吸回收装置201的垃圾桶内完成对地面的清洁工作。
本发明相较于现有技术中的结构设计，加强了对地面的抽吸力度，同时配合前方的吸尘入口能更有效将垃圾收集清理吸走，大大提升了地面的清洁效果；同时，在增强负压抽吸力度后，利用自滚动的滚筒提供带动地刷行走的动力，令用户使用更加轻松。
作为本发明的优选方案，密封胶条5包括后侧刮条51、左右两侧的边部密封条52以及前侧横置的多段密封片53；后侧刮条51可对地面进行二次刮擦，将少量残留水分再次刮起并吸走收集，令清洁后的地面变得更干爽，更容易彻底变干。壳体1底部前侧、即底部敞口21前侧布设有多个安装台11，密封片53固装在安装台11上。多个安装台11可以统一一体设置在支架上安装在壳体1前侧，更有利于安装；且当安装台11通过支架一体成型制造后，可利用二次注塑工艺将密封片53组合在安装台11上，制造更迅速、简单；同样地，后侧刮条51和边部密封条52也可以通过一安装支架进行二次注塑组合成部件，并安装在壳体1底部，令在壳体底部设置密封胶条5变得简单容易。
作为优选，安装台11呈三角形，密封片53固设在三角形安装台的底边且密封片53两端伸出安装台11两侧底角，吸尘入口形成于两个相邻的三角形安装台的底角之间，并由两密封片53端部实现闭合；安装台11两斜边朝向前侧起导向作用形成导向面111，地刷100行进时，由导向面111将垃圾导向至密封片53端部形变打开形成的吸尘入口处，然后被底部敞口21吸走。而为了进一步提升对地面垃圾的收集效果，安装台11底面朝前侧向上倾斜，使地刷100底部前端形成扩口，更有利于进行垃圾的收集，且在导向面111的配合下，将垃圾颗粒引导吸入，进而提升清洁效果。导向面111与壳体底面之间的夹角a为平滑的弧形夹角，垃圾颗粒在经过导向面111时能更顺利地被引导至吸尘入口，避免发生卡住的情况。进一步地，密封片53呈弧形布设在安装台11上，弧形弯曲方向朝向后方具有一定的导向作用，并使密封片53与地刷100前进方向顺向，更容易保持与地面贴合的姿态，且密封片53端部也可在地刷100前进时，更容易受力变形打开吸尘入口将前方垃圾吸入。
作为优选方案，壳体1分为前部和后部，前部呈框形结构，框型的壳体1前端构成滚筒腔2，框型下方敞口形成底部敞口21，上方敞口用于安装滚筒4，且壳体1上方盖合有盖体17将滚筒腔2上方盖合封闭。为了滚筒4能更稳固且方便地实现可拆式安装，滚筒腔2侧壁设有滚筒安装槽22，滚筒4端部设有卡装结构41，通过掀起盖体17将滚筒4由上自下装入滚筒安装槽22内，并将端部的卡装结构41卡入滚筒安装槽22内实现滚筒4的卡装固定。
滚筒4由滚筒电机6带动实现高速自滚动，滚筒电机6布设在壳 体1后部，通过传动机构7与滚筒4传动连接，壳体1后部内形成有抽吸通道3连通抽吸源并设有安放腔13，滚筒电机6以及传动机构7安装在安放腔13内；传动机构7为常见的皮带轮机构。
进一步地，主机200通过壳体1后端的铰接座14实现转动连接，并为了方便地刷100能够移动，在铰接座14两侧设有移动轮15，且壳体1底部设有辅助轮16，令地刷100能够轻松地向前推进。
