一种表面清洁设备 技术领域
本发明涉及家居清洁用品领域，尤其涉及一种表面清洁设备。
背景技术
用于清洗地面的设备，例如洗地机，当前功能已经较为完善，其主要分为半自动洗地机、全自动洗地机、手推式洗地机还有驾驶式洗地机，但是每一种洗地机的工作原理基本大同小异，都是向地面喷洒清水和洗涤剂，在清洗的同时还能够将污水再次吸入洗地机内的污水箱内，从而完成清洗过程。
目前的表面清洁设备，对滚刷的清洗，必须将滚刷单独取下来放进洗衣机或清洗盆中泡水，此清洗过程耗费大量时间和资源，同时内部电池的散热性能较差，污水箱中的杂质容置堵塞下水管道，而且污水箱和清水箱的水位一般需要人眼观察，容易被遗忘而影响正常的使用。
发明内容
本发明针对现有技术的不足，提出了一种结构简单、可以自动清洗滚刷、通过已有元件对电池组件进行有效散热、将杂质与污水分离且带有水位报警系统，保证使用安全且延长其使用寿命的表面清洁设备。

作为本发明的进一步改进，所述控制系统包括PCB板，所述自清洁包括喷水清洗、脱水甩干和污水回收，所述充电座包括容纳清洁头的底盘，所述底盘上设有容置滚刷的集水槽，所述集水槽内设有清洗部件。自清洁开始后，喷水清洗持续一定时间，持续对滚刷进行冲刷，之后停止喷水，滚刷继续转动一定时间，在离心力的作用下完成脱水甩干，在脱水甩干的同时吸力马达组件将清洗后的脏水和垃圾吸走完成污水回收，喷水清洗过程中产生的污水和垃圾收集在集水槽内，不会流出污染外界。清洗部件可采用凸起、刮板、刮齿等可对滚刷进行清洁的部件，在喷水清洗的过程中可以将滚刷上的污渍刮除，提高清洁效果，而在脱水甩干的过程中，可以将滚刷上残留的水分捋下，提高脱水效果。
作为本发明的进一步改进，所述吸力马达组件上设有吸风接头，所述表面清洁设备主机内设有电池盖，且所述电池包组件通过电池盖固定在表面清洁设备主机外壳上，所述电池盖与表面清洁设备主机外壳之间形成电池包组 件安装腔，吸气管一端与吸风接头连通，另一端与电池包组件安装腔连通。通过吸气管将吸力马达组件的吸风接头与电池包组件安装腔连通，可以将由于电池产生热量而形成的局部热空气吸出，以形成对电池包组件的降温。
作为本发明的进一步改进，所述表面清洁设备主机底部设有充电插头，所述充电座还包括充电组件，所述充电组件包括充电针、充电针盖壳、充电针支架和第一弹性件；所述充电针安装在所述充电针支架上，且所述充电针与外界电源电连接；所述充电针盖壳罩设在充电针顶部，且充电针盖壳顶部设有可以露出充电针的通孔；所述第一弹性件的上端抵接所述充电针盖壳，下端抵接充电针支架，还包括第二弹性件，所述第二弹性件的一端抵接在所述充电针支架的下方，另一端抵接在其下方的固定座上，所述固定座连接在所述充电座上。所述充电组件包括充电的第一工作状态和不充电的第二工作状态；在第一工作状态下，表面清洁设备主机放置在充电座上，充电插头与充电针盖壳先接触，将充电针盖壳往下压，使所述充电针盖壳平移露出充电针，使所述充电针与清洁工具主机上的充电插头电连接；在所述第二工作状态下，表面清洁设备主机离开充电座，在第一弹性件的弹力作用下，充电针盖壳自动回位，使所述充电针盖壳上移会转动至遮盖所述充电针的位置保持，从而可保证人体或其他导体无法与充电针接触，避免触电或发生短路。表面清洁设备主机放置在充电座上时，第二弹性件可以使充电针与充电片弹性接触，避免刚性接触压坏充电针。

所述控制系统包括PCB板，所述自清洁包括喷水清洗、脱水甩干和污水回收，所述充电座2包括容纳清洁头的底盘21，所述底盘21上设有容置滚刷131的集水槽211，所述集水槽211内设有清洗部件212。自清洁开始后，喷水清洗持续一定时间，持续对滚刷131进行冲刷，之后停止喷水，滚刷131继续转动一定时间，在离心力的作用下完成脱水甩干，在脱水甩干的同时吸力马达组件123将清洗后的脏水和垃圾吸走完成污水回收，喷水清洗过程中产生的污水和垃圾收集在集水槽211内，不会流出污染外界。清洗部件212可采用凸起、刮板、刮齿等可对滚刷进行清洁的部件，在喷水清洗的过程中可以将滚刷上的污渍刮除，提高清洁效果，而在脱水甩干的过程中，可以将滚刷131上残留的水分捋下，提高脱水效果。
所述吸力马达组件123上设有吸风接头，所述表面清洁设备主机组件12内设有电池盖125，且所述电池包组件124通过电池盖125固定在表面清洁设备主机1外壳上，所述电池盖125与表面清洁设备主机1外壳之间形成电池 包组件安装腔，吸气管126一端与吸风接头连通，另一端与电池包组件124安装腔连通。通过吸气管126将吸力马达组件的吸风接头与电池包组件安装腔连通，可以将由于电池产生热量而形成的局部热空气吸出，以形成对电池包组件124的降温。
所述表面清洁设备主机1底部设有充电插头127，所述充电座2还包括充电组件22，所述充电组件22包括充电针221、充电针盖壳222、充电针支架223和第一弹性件224；所述充电针221安装在所述充电针支架223上，且所述充电针221与外界电源电连接；所述充电针盖壳222罩设在充电针221顶部，且充电针盖壳222顶部设有可以露出充电针的通孔；所述第一弹性件224的上端抵接所述充电针盖壳222，下端抵接充电针支架223，还包括第二弹性件225，所述第二弹性件225的一端抵接在所述充电针支架223的下方，另一端抵接在其下方的固定座226上，所述固定座226连接在所述充电座2上。所述充电组件包括充电的第一工作状态和不充电的第二工作状态；在第一工作状态下，表面清洁设备主机1放置在充电座2上，充电插头与充电针盖壳222先接触，将充电针盖壳222往下压，使所述充电针盖壳222平移露出充电针221，使所述充电针221与清洁工具主机上的充电插头电连接；在所述第二工作状态下，表面清洁设备主机1离开充电座，在第一弹性件224的弹力作用下，充电针盖壳222自动回位，使所述充电针盖壳222上移会转动至遮盖所述充电针221的位置保持，从而可保证人体或其他导体无法与充电针221接触，避免触电或发生短路。表面清洁设备主机1放置在充电座2上时，第二弹性件225可以使充电针221与充电插头127的充电片弹性接触，避免刚性接触压坏充电针221。
污水箱122包括污水箱盒体1221和污水箱盖1222，所述污水箱盒体1221的底部设有污水进口，所述污水箱盒体1221的顶部设有气体出口，所述污水箱盖1222盖设在所述气体出口上，所述污水箱盖上设有贯通的吸气口，所述吸气口与所述吸力马达组件123连通，所述污水箱122还包括气体过滤组件 1223和毛发过滤器1224，所述气体过滤组件1223设置在所述污水箱盖1222的吸气口处，所述污水箱盒体1221内包括从所述污水进口向上延伸的污水管1225，所述污水管1225的出水口高于所述污水进口，所述毛发过滤器1224为敞口盒，其底板上设有多个过滤小孔，所述毛发过滤器1224的底板中间设有从底板向上延伸的进水管，所述进水管套接在所述污水管1225上，所述毛发过滤器1224的进水管的内表面设有台阶面且台阶面抵在所述污水管1225的顶面/所述毛发过滤器直接或间接的连接在所述污水箱盖1222上。在表面清洁设备使用过程中，在吸力马达123作用下吸入污水箱122中的污水会首先经过毛发过滤器1224的过滤，将毛发等较大的杂质留在毛发过滤器1224内，而经过过滤的污水进入污水箱122，清洁完成后，先将毛发过滤器1224内的杂质导入垃圾桶，而污水箱122内的污水可直接倒入下水道中，不存在堵塞下水道的危险；而气体过滤组件1223可以有效的保护吸力马达123，过滤小孔将较大的垃圾杂质拦截，毛发过滤器1224通过其进水管套设在污水管上，可以保证污水管中的污水首先由进水管进入毛发过滤器进行过滤，再流入污水箱盒体1221。
污水箱水位检测系统包括污水报警装置，所述污水箱122底部设置有安装孔111，所述污水报警装置与所述表面清洁设备电连接，所述污水报警装置包括连接管31、感应组件32，所述连接管31两端通过气密连接器分别与所述安装孔111和感应组件32连接，所述感应组件32包括设置有气压传感器321的电路板322以及报警器323，所述电路板322通过气密连接器与所述连接管31连接，所述感应组件32与所述控制系统电连接，所述连接管32与所述电路板322连接端位于所述气压传感器321正下方。所述连接管31两端通过气密连接器分别与感应组件32连接和所述污水箱122的安装孔111连接，并且所述连接管31与所述感应组件32的电路板322连接，且所述连接管31正对所述气压传感器321，所述污水箱122、连接管31以及所述感应组件32形成气密封连接，随着所述表面清洁设备的开启，所述吸力马达组件123将 污水吸入到污水箱122内，使所述连接管31内的气体气压发生变化，从而引起气压传感器321发生变化，所述气压传感器321将信号传输至控制系统，发出报警信号，提示用户污水箱即将装满，该装置结构简单，测量精度高，反应速度快，不受外界温度的影响，通过气压传感器321测量气体压强的大小的方法实现对污水箱内水位的检测，不需要人工观察污水积累量，水满后控制系统通过报警部件向用户发出报警，提高了表面清洁设备的使用体验。
所述表面清洁设备主机内部设有水泵14，清水箱为可拆卸清水箱121，所述可拆卸清水箱121连接至水泵14入水口端，所述水泵14上设置有工作电流检测装置，并由电池包组件124提供电源，还包括警报提醒装置，所述警报提醒装置与所述工作电流检测装置连接，所述工作电流检测装置为欠流继电器51，所述欠流继电器51触发阈值为水泵14空载工作电流。通过监测水泵14的工作电流对于其是否处于空载工作状态进行判定，进而实现对于可拆卸清水箱121缺水状态实现即时监测及报警。
所述警报提醒装置包括控制模块41及指示模块42，欠流继电器51连接至所述控制模块41信号输入接口，所述控制模块41控制信号输出端连接至所述指示模块42信号输入接口。欠流继电器51其控制精度高，监测范围可控，成本低廉，当通过欠流继电器51的电流减小到低于其整定值时触发动作；而水泵14其空载电流较负载电流较小，故可依据水泵14其空载电流值设定欠流继电器51触发阈值。实际工作时，当水泵14工作电流处于欠流继电器51阈值以上时，说明水泵14处于负载工作状态，清水箱121内不存在缺水风险，不触发后续警报动作；当水泵14工作电流低于欠流继电器51设定阈值时，说明水泵14因清水箱121内无水流出处于空载状态而使得工作电流变小，清水箱121内处于缺水状态，触发欠流继电器51进行后续警报动作；欠流继电器51触发时，输出信号至控制模块41，继而其输出控制信号至指示模块42，实现清水箱121缺水报警；所述指示模块42包括信号灯43及声音警示元件44，当清水箱121内缺水时，欠流继电器51因电流过低经控制模块41 触发指示模块42，使得信号灯43亮起，同时声音警示元件44发出声音警示信号，以警告使用者，清水箱121内处于缺水状态，需关闭水泵14并进行清水箱121拆卸补水，避免对于设备造成空载损伤。
清洁头组件13包括滚刷壳133，所述滚刷壳133内形成滚刷腔体；所述滚刷腔体内设有圆柱形滚刷131、滚刷齿轮134、轴承135、密封圈136和密封圈支架137；所述滚刷131中心为空心结构，所述滚刷齿轮134的一端伸入所述滚刷131的空心结构内部；所述密封圈136固定在密封圈支架137上，且位于所述滚刷齿轮134和轴承135之间，所述滚刷齿轮134包括锯齿端1341和连接轴1342，所述锯齿端1341和连接轴1342的直径不同，所述锯齿端1341和连接轴1342之间形成轴肩1343；所述密封圈136包括主体圈1361、第一密封齿1362和第二密封齿1363，所述第一密封齿1362凸出于所述主体圈1361的一端端面，所述第一密封齿1362与所述轴肩1343之间形成第一级密封，所述主体圈1361的内部设有倾斜面，所述倾斜面的端部形成第二密封齿1363，所述第二密封齿1363与所述连接轴1342的外周之间形成第二级密封。通过密封圈的密封结构，可以有效的过滤毛发和水，防止其进入滚刷的空心结构内，同时可以防止毛发缠绕轴承135，而密封圈支架137便于密封圈136的安装和定位。第一级密封可以过滤毛发和水，防止其进入到滚刷内部，随着使用时间的延长，当第一级密封失效时，第二级密封能够继续发挥作用，起到防水和防止毛发缠绕的作用。
在第二实施例中：污水箱水位检测系统与第一实施例不同，其他结构不变。
污水箱水位检测系统包括污水报警装置6，所述污水报警装置6包括吸管61、位于所述污水箱122内的浮子62、设置有气压传感器63的电路板64以及报警器65，所述电路板64通过所述吸管61与所述污水箱122连接，所述控制系统分别与所述污水报警装置6和报警器61电连接，所述污水箱122的气体出口通过吸管连接头66与所述吸管61连接，所述吸管61与所述电路板 64连接端位于所述气压传感器63正下方。所述吸管61一端通过所述吸管连接头66与所述污水箱122的出气口紧密连接，另一端与所述电路板64连接，且所述吸管61正对所述气压传感器63，所述浮子62设置在所述污水箱122的滑槽内，使浮子62能够上下移动，所述浮子62在自身重力以及污水箱122内污水的浮力的作用下上下浮动，使污水箱122和吸管61内的气流气压发生变化从而引起气压传感器63发生变化，并将信号传输至控制系统，发出报警信号，该装置结构简单，测量精度高，仅通过气压的变化即可测定污水箱内的液位变化，不需要人工观察污水积累量，提高了表面清洁设备的使用体验。
在第三实施例中：污水箱水位检测系统与第一实施例、第二实施例不同，其他结构不变。
污水箱水位检测系统包括设置于所述污水箱122底壁上的第一电极611、设置于所述污水箱122的最高水位处的第二电极612、污水报警装置6，所述第一电极611与所述第二电极612分别与表面清洁设备的控制系统的检测电路连接；所述第一电极611和所述第二电极612能够以所述污水箱122内的污水为导电介质进而与所述控制系统的检测电路形成回路以控制所述污水报警装置6发出警报，以实现监测表面清洁设备污水箱122的水满状态。
在本实施例中，第二电极612安装在污水箱122的侧壁上，其安装高度为污水箱122的最高水位处。
在本实施例中，表面清洁设备还包括设置于所述污水箱122与所述表面清洁设备主机1之间的定位装置3；所述定位装置3包括设置于所述表面清洁设备主机1上的接触片和设置于所述污水箱122上的导电件，所述接触片与控制系统的检测电路电性连接，且所述导电件与所述接触片的位置相互对应。

此外，在其他情况下，第二电极612也可以安装在污水箱122的底壁上，而第二电极612本身具有一定的高度，其高度近似于污水箱122的水位高度，其顶端为可导电的部分，只有污水达到一定的高度，淹没其顶端的导电部分后才能形成导通回路，使污水报警装置6发出信号提醒污水箱已满，此时，对应的第二接触片312安装在表面清洁设备主机1的安装污水箱122的腔体的底部。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明实施例技术方案。
