Description

用于清洁机器人的抹布及采用该抹布的清洁机器人 技术领域
本实用新型涉及一种用于清洁机器人的抹布及采用该抹布的清洁机器人，属于小家电技术领域。
背景技术
现代生活中清洁机器人已经渐渐的变得不可或缺。怎样用较小的功率将机器人吸附在玻璃等平面上是其一个技术要点。中国专利201420119672.X公开了一种擦玻璃的吸附机器人，如图1所示，其机体底部形成一个负压室400，该负压室400由机体、抹布2和玻璃围设形成。通过风机4对负压室400抽真空，使机器吸附在玻璃表面，抹布2作为构成负压室400的一部分，如果不具备良好的密封性，容易导致负压室400内漏气，机器吸附不牢固。其采用的抹布2是普通海绵，其虽具有良好的压缩特性，但透气性太好，容易造成负压外泄，不利于机器人吸附。
发明内容
本实用新型所要解决的技术问题在于针对现有技术的不足，提供一种用于清洁机器人的抹布。该抹布具备较好的弹性和密封性，可有效改变普通抹布的透气性，克服容易造成负压外泄的问题。
本实用新型所要解决的技术问题是采用如下技术方案实现的：
本实用新型提供一种用于清洁机器人的抹布，该抹布包括一层与被清洁表面相接触的擦拭布，该抹布还包括靠近机器人底座的可拆卸连接部件以及位于擦拭布和可拆卸连接部件之间的弹性密封层。
优选的，所述的弹性密封层为发泡EPDM材料。
优选的，所述的弹性密封层为自结皮海绵。
优选的，所述的弹性密封层包含普通海绵及在该普通海绵的上下至少一侧设有的一层密封薄膜。
优选的，所述可拆卸连接部件为魔术贴。
本实用新型还提供一种清洁机器人，它包括行走单元，抽真空单元和负压空间，抽真空单元包括风机电机、风叶；负压空间由底座、被清洁表面和抹布围设而成，所述抹布包括一层与被清洁表面相接触的擦拭布该抹布还包括靠近机器人底座的可拆卸连接部件以及位于擦拭布和可拆卸连接部件之间的弹性密封层。
所述弹性密封层由发泡EPDM材料、自结皮海绵或者普通海绵的上下表面加上至少一层密封薄膜组成。
本实用新型魔术贴与擦拭布之间贴合弹性密封层的结构，具备较好的弹性，且大大的提高了清洁机器人负压室的密封性。
下面结合附图和具体实施例对本发明的技术方案进行详细地说明。
附图说明
图1是现有技术吸附机器人的结构示意图；
图2是本实用新型清洁机器人的结构示意图；
图3是本实用新型实施例一发泡EPDM材料抹布的结构示意图；
图4是本实用新型实施例二自结皮海绵抹布的结构示意图；
图5是本实用新型实施例三海绵抹布的结构示意图。
具体实施方式
以下结合图2-图5对本实用新型的抹布进行说明。
图2是本实用新型清洁机器人工作时的部分剖面示意图，如图2所示，清洁机器人包括行走单元，抽真空单元和负压空间17。在本实施例中，行走单元为驱动带15；抽真空单元包括风机电机11、风叶12；负压空间17由底座13、被清洁表面16和抹布2围设而成。当风机电机11带动风叶12旋转，抽出负压空间17中的空气，使得这个负压空间17里面迅速形成小于外界大气压的压强P，机器人就可以在这个压力差的作用下吸附在被清洁表面16上。
实际上在这个过程中，空气一直会通过抹布2进入负压空间17。如果抹布2的密封性不好的话，压强P则无法达到一个比较小的值。有鉴于此，本实用新型提供了一种密封性良好的抹布。包括靠近机器人底座13的可拆卸连接部件、与被清洁表面相接触的擦拭布和位于它们之间的弹性密封层，该弹性密封层由发泡EPDM材料、自结皮海绵或者普通海绵加上该普通海绵上下至少一侧设有的一层密封薄膜组成。其中该可拆卸连接部件可以为一种高分子材料制成的钩环式连接物件，例如俗称的魔术贴或子母扣，所述魔术贴可拆卸的贴附于机器底座13，以便适当时候换下清洗；擦拭布则是为了清洁工作面，而弹性密封层则是为了当机器被大气压压在清洁表面时更好的与清洁表面贴合。下面参照图3-图5对本实用新型的三个实施例进行说明。
实施例一
图3是本实用新型实施例一的结构示意图。如图3所示，本实用新型的抹布分为三层，最上面一层(即靠近底座13的一层)是魔术贴21，最下面一层是擦拭布22，弹性密封层为发泡EPDM(三元乙丙橡胶)材料23，该发泡EPDM材料的两面分别与魔术贴21和擦拭布22贴合。由于EPDM材料的特性，在保证其弹性性能的条件下可以有效的提高空间17的密封性。
实施例二
图4是本实用新型实施例二的结构示意图。如图4所示，本实施例与实施例一不同之处在于其弹性密封层被替换为自结皮海绵33。自结皮海绵不同于一般海绵，它依靠发泡组分在发泡成型时一次性形成表皮与泡沫芯材。自结皮海绵由于其表面结皮阻断了部分外界气流进入空间17时上下流动的通路，因而增加了空间17的密封性。
实施例三
图5是本实用新型实施例三的结构示意图。如图5所示，本实施例与实施例一、二的不同之处在于弹性密封层包含普通海绵43及在该普通海绵上下至少一侧设有的一层密封薄膜24，较佳的，在普通海绵的外周均设密封薄膜，当普通股海绵的厚度较薄，如2-3mm，则仅需上下至少一侧密封。在本实施例中所述普通海绵43的两侧分别设有一层密封薄膜21，即该普通海绵43与最上层的魔术贴21、最下层的擦拭布22之间分别设有一层密封薄膜24。该密封薄膜可以是塑料薄膜。由于薄膜的存在阻断了部分外界气流进入空间17时上下流动的通路，同样可以达到加强密封性的目的。
当然所述密封薄膜24也可用于实施例一和实施例二的弹性密封层的至少一侧，其密封性能更佳。
综上所述，本实用新型魔术贴与擦拭布之间贴合的由发泡EPDM材料、自结皮海绵或者普通海绵加上在该普通海绵至少一侧设有的密封薄膜组成的弹性密封层结构，具备较好的弹性，且大大的提高了清洁机器人负压室的密封性。
