手持式吸尘器是家用吸尘器的一种形式，它具有外型轻巧，操作方便，使用范围广泛等优点，深受消费者青睐。地刷是手持吸尘器的关键部件，传统的地刷主要有如下两种形式：一种是直吸型，地刷上不设有滚刷，工作时通过地刷上的吸口直接将垃圾吸入；这种地刷的优点是：结构简单，重量较轻，成本低廉，缺点是除尘效率偏低，地刷只能吸除吸口附近的垃圾；另一种是带电动滚刷型，其由电机驱动一个或多个滚刷辅助将灰尘扫起然后由吸口吸入；这类地刷的优点是：除尘效率较高，但缺点是成本高、重量重，且易缠毛发。
发明内容
因此，本申请所要解决的技术问题是提供一种结构简单、除尘效率高的地刷及具有其的清洁机器人。
为解决上述技术问题，本申请提供一种地刷，用于清洁待清洁表面，包括：地刷本体，设有开口朝向待清洁表面的地刷腔，所述地刷腔的腔壁上设有吸口；气旋发生组件，设于所述地刷本体上，且位于所述地刷腔的端部处，用于在所述地刷腔内产生能够刮擦待清洁表面的气旋；其中，当所述吸口处于负压状态时，外部空气通过所述气旋发生组件进入 所述地刷腔后，以涡旋的状态朝向所述吸口的方向流动。

请参阅图1至图4所示，本申请提供了一种地刷，用于清洁待清洁表面，在一种示意性的场景中，所述地刷可以为用作为手持吸尘器的地刷，用于清扫地面垃圾。值得注意的是，上述举例中所述地刷被用作为手持吸尘器的地刷，仅是所述地刷一种可行的适用场景。在其他可行且不可被明确排除的场景中，所述地刷也可以用作为洗地机的地刷。
下文将主要以所述地刷用作为手持吸尘器的地刷为主述场景来阐述的，上述待清洁表面为地面。但基于上文描述可知，本申请实施例的保护范围并不因此而受到限定。
在本实施例中，所述地刷包括地刷本体100和设于地刷本体100上的气旋发生组件200。地刷本体100上设有开口朝向待清洁表面的地刷腔110，气旋发生组件200位于地刷腔110的端部处，用于在地刷腔110内产生能够刮擦待清洁表面的气旋。
其中，地刷腔110的腔壁上设有吸口120，所述地刷上还设有通过上述吸口120与地刷腔110连通的进污通道121，进污通道121通过上述吸口120将地刷腔110内的垃圾吸入机体(图中未示意)。
具体而言，当所述地刷工作时，与所述地刷连接的机体内产生抽吸气流，可使得吸口120处于负压状态，此时，外部空气通过地刷本体100与地面之间的间隙、气旋发生组件200进入地刷腔110内。在外部空气经过气旋发生组件200时，气旋发生组件200能够迫使气流转动，从而使得气流以涡旋的状态朝向吸口120的方向流动，最终通过上述吸口120进入进污通道121内。上述“涡旋的状态”是指气流沿顺时针方向或是逆时针方 向转动而形成的气旋，类似龙卷风。
在气流以涡旋的状态朝向吸口120运动的过程中，旋转气流(气旋)刮擦地面，将地刷腔110区域内的垃圾卷送至吸口120附近，从而使得垃圾被吸口120吸除。
与传统的地刷相比，本申请的所述地刷利用气旋清扫地面，一方面可解决传统直吸型地刷除尘效率偏低的问题，另一方面，可代替传统的电动滚刷，解决带有电动滚刷的地刷易缠毛发的问题，同时，还可以简化地刷的结构，从而达到降低地刷的成本和重量的目的。
在本实施例中，气旋发生组件200的数量为一对，分布于吸口120的两侧。上述“两侧”为所述地刷的前进方向的两侧。若将所述地刷的前进方向定义为前方，那么所述地刷前进方向的两侧为所述地刷的左右两侧，也就是说，气旋发生组件200分布于吸口120的左右两侧。
进一步地，气旋发生组件200具有驱使气流按预设方向转动的旋向，上述“旋向”可以理解为顺时针方向或是逆时针方向。在本实施例中，位于吸口120两侧的气旋发生组件200的旋向相反，例如，当位于吸口120左侧的气旋发生组件200的旋向为顺时针时，那么位于吸口120右侧的气旋发生组件200的旋向则为逆时针，反之亦然。也就是说，位于吸口120两侧的气旋发生组件200呈镜像分布。
当外部空气经过两侧的气旋发生组件200进入地刷腔110内时，将在地刷腔110内产生两个气旋，分别位于吸口120的左右两侧，上述气旋在地刷腔110内转动的同时还沿着地刷腔110移动，其中，位于吸口120右侧的气旋由右至左的方向朝向吸口120运动，位于吸口120左侧的气旋由左至右的方向朝向吸口120运动。
具体地，上述两个气旋在地刷腔110内刮擦地面，将进入地刷腔110区域的垃圾卷送至吸口120附近以被吸除，同时，由于两个气旋总体是向吸口120方向流动，即由边侧向中心方向流动，能够将地刷腔110两侧边角区域内的灰尘输送至吸口120附近，具备沿边除尘能力，从而提高除尘效 率，具有除尘效果好的优点。
在本实施例中，地刷腔110为锥形腔，在沿气旋发生组件200至吸口120的方向上，地刷腔110的流通截面呈逐渐减小的态势，以使靠近吸口120处的气旋速度大于气旋发生组件200处的气旋速度，有利于垃圾被吸口吸除，提高了气旋的清洁效果。
为了便于吸口120吸除垃圾，气旋发生组件200所形成的气旋使得靠近待清洁表面侧的气流朝向吸口120方向流动，以利于吸口120吸除垃圾。反正，若气旋发生组件200所形成的气旋不能使得靠近待清洁表面侧的气流朝向吸口120方向流动，那么，地面上的垃圾在气旋的作用下朝向远离吸口120的方向吹送，不利于吸口120将垃圾吸入进污通道121内。
关于气旋发生组件200，在本实施例中，气旋发生组件200为固设于地刷本体100上的叶轮。请参阅图2所示，叶轮包括中心轴210、沿着中心轴210的周向方向等间隔设于中心轴210外圆周壁面上的叶片220。地刷本体100的左右两侧端面上设有安装孔，叶轮固设于上述安装孔内。其中，叶片220的一端固设于中心轴210的外圆周壁面上，另一端固设于安装孔的内壁上。相邻的叶片220之间形成有用于连通地刷腔110与外界环境的风道。
具体地，风道用于在外界空气通过气旋发生组件200时使得气流具有旋转运动的态势，从而使得进入地刷腔110内的气流以涡旋的状态朝向吸口120的方向流动。进一步地，上述风道呈螺旋状，风道的旋向即为气旋发生组件200的旋向。由于气旋发生组件200以镜像的方式分布于吸口120的左右两侧，两侧的气旋发生组件200的旋向相反，例如，一侧为左旋式风道，另一侧为右旋式风道。
在本实施例中，叶轮可以通过紧固件(图中未示意)、卡扣、螺纹连接等方式固设于地刷本体100上，上述紧固件可以为螺母、螺钉等。当然，叶轮还可以与地刷本体100一体成型，在本实施例中，优选的叶轮为地刷本体100的外壳的一部分。由此，在减少零件数量的同时，具有美观 大方的优点。
关于地刷腔110的结构，请继续参阅图2所示，在本实施例中，地刷腔110为对称结构，地刷腔110具有对称分布的第一腔体111和第二腔体112，吸口120关于地刷腔110的对称面X对称。
其中，地刷腔110的结构有如下两种情况：第一种情况，请参阅图4所示，第一腔体111与对称面X之间的夹角为直角，地刷腔110呈直线状分布；第二种情况，请参阅图1至图3所示，第一腔体111与对称面X之间的夹角为锐角，地刷腔110呈折线状分布。可以理解地，由于地刷腔110为对称结构，在上述第一种情况下，第二腔体112与对称面X之间的夹角也为直角；在上述第二种情况下，第二腔体112与对称面X之间的夹角也为锐角。
当地刷腔110在上述第一种情况下，地刷本体100呈直条状；当地刷腔110在上述第二种情况下，地刷本体100呈“Y”字型。在本实施例中，优选的地刷本体100呈“Y”字型，这样更有利于将垃圾输送至吸口120。
在本实施例中，请参阅图2所示，地刷腔110的开口的前边缘面向上凹陷形成有多个豁口130，豁口130被配置为局部增大所述地刷底部的前边缘面与地面之间的间距值。上述“局部”可以理解为上述豁口130是间隔设置的。由此，颗粒较大的垃圾能够通过上述豁口130进入地刷腔110内，并在气旋的作用下被吸口120吸除。
进一步地，所述地刷的底部还设有第一滚轮320和第二滚轮310，第一滚轮320和第二滚轮310用于带动所述地刷在地面上移动。第一滚轮320位于上述地刷腔110的后方，第二滚轮310位于上述地刷腔110的前方，其中，第二滚轮310设于上述凹设有豁口130的前边缘面上。
第一滚轮320的数量为一个，第二滚轮310的数量为两个，第一滚轮320和第二滚轮310形成三角形支撑，由此，所述地刷具有移动平稳、可靠的优点。
本申请还提供了一种清洁机器人，所述清洁机器人包括机体(图中 未示意)和如前所述的地刷。请参阅图1所示，所述地刷上设有连接部400，连接部400用于连接上述机体与所述地刷。
显然，上述所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下，可以做出其它不同形式的变化或变动，都应当属于本申请保护的范围。
