Description

一种地刷及包括该地刷的扫地机 技术领域
本申请涉及清洁设备技术领域，尤其涉及一种地刷及包括该地刷的扫地机。
背景技术
扫地机在对地面进行清洁时，其滚刷上不可避免地会吸附到毛发、毛线等较长异物；异物经长时间积累会影响地刷的正常使用。因此，地刷在使用一段时间后，需要用户自行对其进行拆卸，并对缠绕在滚刷上的毛发进行手动清理，从而降低了用户的使用体验。鉴于此，如何设计一种不容易缠绕上异物，并能够对较长异物进行自动清理的地刷、扫地机成为了目前亟待解决的技术问题。
发明内容
针对上述技术中存在的不足之处，本申请提供了一种地刷及包括该地刷的扫地机，能够降低异物缠绕在地刷上的风险。
本申请解决其技术问题所采用的一技术方案是：
一种地刷，包括：旋转设置的滚刷体；至少两根滚刷体毛条，大致沿滚刷体的轴向绕设于滚刷体的外周面上，且具有至少一个弯折段；以及凸设于滚刷体外周面上的顺毛筋，其与滚刷体毛条缠绕方向一致，并与滚刷体毛条间隔设置，用于增大滚刷体的最大缠绕长度，以降低异物缠绕在滚刷体外周面上的概率。
优选的，滚刷体毛条包括至少一个硬毛条和至少一个软毛条；硬毛条和软毛条相间隔的设置在滚刷体上。
优选的，顺毛筋包括与滚刷体连接的接合部和设置在接合部上的凸筋，凸筋通过接合部固设于滚刷体上，且凸筋的朝向基本沿滚刷体的径向设置。
优选的，顺毛筋在滚刷体外周面上的露出高度小于等于滚刷体毛条在滚刷 体外周面上的露出高度。
优选的，硬毛条包括衬底；间隔设置在衬底上的第一子毛条和第二子毛条，第一子毛条的硬度大于第二子毛条的硬度；其中，第一子毛条用于清扫异物，第二子毛条用于支撑异物，以使异物浮在第一子毛条的顶端而不陷入。
优选的，第二子毛条数量至少为两个；相邻第二子毛条之间配置有至少一个第一子毛条。
为解决上述技术问题，本申请采用的另一技术方案是：
一种扫地机，包括如上所述的地刷，还包括一内部形成有腔体的壳体；其中，腔体中配置有用于安装地刷的端盖，端盖和滚刷体的安装间隙中设置有能够阻止异物进入的间隔物；部分间隔物外露于端盖在滚刷体上的投影区，以使位于端盖外周面上的异物在滚刷体转动过程中能够从通过间隔物过渡到滚刷体的外周面上。
优选的，间隔物的外缘部高于顺毛筋的外缘部，且高于滚刷体与间隔物的连接端部；以使间隔物从端盖的端面平滑过渡到顺毛筋上。
优选的，间隔物为植毛，滚刷体上设置有从动件；植毛的根部固定在滚刷体的圆周面上或从动件上；其中，植毛的延伸方向与滚刷体的轴向大致平行。
优选的，腔体中限定有壳体毛条，壳体毛条与滚刷体毛条间具有交叠区，以在滚刷体滚动时，将缠绕于滚刷体毛条上的异物聚集至弯折段。
优选的，壳体毛条呈直线型设置，且其与滚刷体毛条的交叠量大于滚刷体毛条露出滚刷体外长度的50％。
优选的，滚刷体毛条的弯折段位于滚刷体的中间位置；其中，壳体上成型有抽风口，抽风口与弯折段对应设置。
本申请与现有技术相比，其有益效果是：本申请提供的地刷，在滚刷体上绕设了间隔配置的滚刷体毛条和顺毛筋，并在端盖和滚刷体的安装间隙中设置了间隔物；通过上述方式，顺毛筋增大了头发在滚刷体上的缠绕半径，使得异 物不容易被缠绕在滚刷上，间隔物使缠绕在端盖上的头发等异物能够被过渡到滚刷体上，从而有效地避免了头发等异物进入到端盖内或被缠绕在端盖上。

具体实施方式
下面结合附图对本申请做进一步的详细说明，以令本领域技术人员参照说明书文字能够据以实施。
如图1-10所示，本申请提供了一种地刷结构，其包括一形成有腔体的壳体1，腔体内设置了用于安装滚刷体2的端盖7；滚刷体2能够在扫地机动力件的作用下，与地面滚动接触以对地面进行清洁。
作为本申请的一实施例，滚刷体2上设置有用于对地面进行清扫的滚刷体毛条3；在具体的应用场景下，滚刷体毛条3的数量可以为两个，也可以为两个以上；为了使说明书附图更加简单明了，本实施例附图中仅表示了两个滚刷体毛条3。
具体地，滚刷体毛条3大致沿滚刷体2的轴向缠绕在滚刷体2的外周面上； 且滚刷体毛条3上具有至少一个弯折段30，以当滚刷体2相对端盖7进行滚动时，缠绕在滚刷体毛条上的头发、毛线、绒毛等其他异物能够被聚集在上述弯折段30处。可以理解的是，滚刷体毛条3可以配置呈V型、W型或多段正弦型，其尖端处即为上述的弯折段30处。
为了使地面能够得到有效地清洁，滚刷体毛条包括有至少一个第一毛条和至少一个第二毛条；其中，第一毛条和第二毛条相间隔的设置在滚刷体2上，第二毛条的平均硬度小于第一毛条的平均硬度。为方便描述，下面以第一毛条为硬毛条31，第二毛条为软毛条32进行举例说明。
进一步地，硬毛条31包括衬底310，衬底310上间隔设置有用于清扫异物的第一子毛条311和用于支撑异物的第二子毛条312；其中，第一子毛条311的硬度大于第二子毛条312的硬度。
在具体的应用场景下，第一子毛条311可以为一个，第二子毛条312可以为两个，第二子毛条312配置在第一子毛条311的两侧，使得缠绕在滚刷体毛条上的异物能够在第二子毛条312的作用下浮在滚刷体毛条的表面，而不陷入第一子毛条311中。当然，第二子毛条312的数量还可以是两个以上，相邻第二子毛条312间配置有一个或多个第一子毛条311；两者的设置关系能够满足缠绕在滚刷体毛条上的异物不陷入第一子毛条311中即可。
为了便于理解，举例来说，本申请中将第二毛条、第一子毛条311、第二子毛条312的硬度值分别限定为a、b、c；在第一子毛条311为一个、第二子毛条312为两个的应用场景下，上述第一毛条的平均硬度为d，即d＝(2*c+b)/3。进一步可理解，b>c，且b>d>a。
考虑到滚刷体毛条3在使用一段时间后可能发生磨损、变形、掉落或断裂的状况，滚刷体毛条3可拆卸地设置在滚刷体2上。具体的，滚刷体2上成型有倒T型的安装槽口，滚刷体毛条3的安装端(包括上述的衬底)能够沿滚刷体2的轴向插接在安装槽口中。
本申请的发明人在长期研发过程中发现，滚刷直径越大，头发缠绕在滚刷上的难度就越大。然而，如果单方面增加滚刷的直径，会导致整个地刷的体积增大，并显得笨重。
鉴于此，在滚刷体2上还凸设了顺毛筋20，以增大异物在滚刷体2上的最大缠绕长度，即增大了头发等异物在滚刷体2上的缠绕半径。具体的，顺毛筋20和滚刷体毛条3间隔设置，并和滚刷体毛条3具有相同的弯折段30及缠绕方向。其中，顺毛筋20在滚刷体2外周面上的露出高度小于等于滚刷体毛条3在滚刷体2外周面上的露出高度，从而使得滚刷的体积不增大。
具体地，顺毛筋20包括与滚刷体2连接的接合部201和设置在接合部201上的凸筋202；为了能够更加有效地增大异物在滚刷体2上的缠绕半径，凸筋202的朝向基本沿滚刷体2的径向设置。
为了不产生额外的制造成本，顺毛筋20和滚刷体2采用相同的制作材质。顺毛筋20可以和滚刷体2一体成型设置，也可以通过植筋、粘合等常规方式固定在滚刷体2上。
在滚刷的清扫过程中，端盖7上缠绕到异物后，难以直接过渡到滚刷体上；由此，本申请中在端盖7和滚刷体2的安装间隙中设置了间隔物9，其外缘部91高于顺毛筋20的外缘部201，且高于滚刷体2与间隔物9的连接端部21，以使得位于间隔物9上的异物能够顺滑过渡到滚刷体2上。进一步地，间隔物9从端盖7的端面平滑过渡到顺毛筋20上，以使得位于端盖7上的头发能够在滚刷体2高速旋转时通过间隔物9过渡到滚刷体2上。
为了使位于端盖7上的异物能够过渡到间隔物9上，间隔物9的安装面低于端盖7的内表面不少于1mm且部分间隔物9外露于端盖7在滚刷体2上的投影区。
在具体的应用场景下，间隔物9可以为软绒、植筋、植毛中的至少一种。当间隔物9为软绒时，其可以固定在滚刷体2上，并跟随滚刷体2相对端盖7 旋转运动；其中，软绒的固定方式可以选择粘连、一体成型或者植绒等常规手段。当间隔物9为植筋或植毛时，其根部可以固定在滚刷体2的圆周面上，也可以设置在随滚刷体2同步滚动的从动件8上；另外，植毛的延伸方向可以沿滚刷体2的轴向延伸，从而使得植毛的顶部正对异物，以使滚刷具有较好的防异物的效果。
考虑到缠绕在滚刷上的异物不容易全部被有效地清理出，本申请在壳体1的腔体内设置了壳体毛条4，其与滚刷体毛条3间具有交叠区，用于对缠绕在滚刷体2上的头发进行梳理。进一步地，壳体毛条4的端部朝向滚刷体2设置；壳体毛条4为硬毛条。
为了使滚刷体2上的头发能够得到有效梳理，壳体毛条4呈直线型设置，且其与滚刷体毛条3的交叠量大于滚刷体毛条3露出滚刷体2外长度的50％。由此，当滚刷体2带动滚刷体毛条3朝向壳体1上成型的抽风口10转动时，滚刷体毛条3和壳体毛条4间能够充分交叠的发生相对运动；进而使缠绕在滚刷体2上的头发能够被壳体毛条4挤推至滚刷体毛条3的弯折段30，从而便于地刷结构从抽风口10将头发吸出。
具体地，当滚刷体毛条3具有一个弯折段30时，抽风口10可以设置成一个并正对于该弯折段30，以达到较好的吸出异物的效果；当滚刷体毛条3具有多个弯折段30时，抽风口10可以设置成多个，以和多个弯折段30相对应。
考虑到当缠绕在滚刷体2上的头发过长或缠绕密集时，有可能不容易被壳体毛条4梳理，腔体中设置有若干梳齿5，其与滚刷体毛条3间具有交叠区，用于对缠绕在滚刷体2上的头发进行拉扯，使头发被拉断。
进一步地，若干梳齿5呈直线型设置，其齿尖朝向于滚刷体2。
梳齿5的齿尖与滚刷体毛条3的交叠量大于滚刷体毛条3露出滚刷体2外长度的50％；这样以来，能够使梳齿5和滚刷体毛条3充分交叠，在滚刷体2转动作业时，梳齿5可以稳定地对缠绕在滚刷体2上的头发进行梳理。
考虑到具有弯折段30的滚刷体毛条3会导致头发斜着缠绕在滚刷体2上，且头发和滚刷体毛条3会发生钩挂，若干梳齿5呈两种分布密度设置：位于中间位置的梳齿5的分布密度大于位于两端部位置的梳齿5的分布密度。
通过上述方式，两端较疏的梳齿5能够将头发拨开，使头发活动起来；同时，中间较密的梳齿5除了能将头发拨开外，还能够把打结的头发拉断，以使得抽风口10较容易地将头发吸走。
作为本申请一实施例，腔体中固定有一安装座6，壳体毛条4和梳齿5均安装在安装座6上；具体的，壳体毛条4可拆卸地设置在安装座6上，梳齿5和安装座6一体成型设置。
本申请提供的地刷结构可以应用到扫地机上，用于对地面进行清洁。
综上所述，本申请中通过将间隔物9与滚刷体2接触的一端端面的高度设置成大于滚刷体2的高度，并包覆住顺毛筋20的端部，使得缠绕于端盖上的头发会被过渡到滚刷体上；并通过在滚刷体2上设置的顺毛筋20在没有改变滚刷直径且没有增加滚刷体积的前提下，增大了头发在滚刷体2上的缠绕半径，使得头发更不容易被缠绕在滚刷上；由于在壳体1的腔体中设置了壳体毛条4和若干梳齿5，其能够配合具有弯折段30的滚刷体毛条3对头发进行稳定地聚中梳理，并由抽风口10将碎发直接吸出；其中，壳体毛条4用于将头发挤推至滚刷体2的中间部位，梳齿5用于将头发拨开，并用于将头发拉断，以便于吸出头发。
尽管本申请的实施方案已公开如上，但其并不仅限于说明书和实施方式中所列运用，它完全可以被适用于各种适合本申请的领域，对于熟悉本领域的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本申请并不限于特定的细节和这里示出与描述的图例。
