具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
在具体实施例中所描述的各个具体技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合，例如通过不同的具体技术特征的组合可以形成不同的实施例和技术方案。为了避免不必要的重复，本申请中各个具体技术特征的各种可能的组合方式不再另行说明。
在以下的描述中，所涉及的术语“第一\第二...”仅仅是区别不同的对象，不表示各对象之间具有相同或联系之处。应该理解的是，所涉及的方位描述“上方”、“下方”、“外”、“内”均为正常使用状态时的方位，“左”、“右”方向表示在具体对应的示意图中所示意的左右方向，可以为正常使用状态的左右方向也可以不是。XYZ坐标系是正常使用状态时的绝对坐标。所涉及的方位描述“正向”为坐标系中箭头所示的方向，“负向”为坐标系中箭头所示相反的方向。
需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。“多个”表示大于或等于两个。
本申请实施例提供一种滚刷组件，该滚刷组件可应用于吸尘器、扫地机、拖地机及扫拖一体机等清洁设备中。需要说明的是，本申请实施例的 应用场景类型并不对本申请实施例的滚刷组件的结构产生限定。
如图1所示，以下以滚刷组件应用在吸尘器例对其用途进行说明：
吸尘器的座体6的前侧底部敞开，以在座体6的前侧底部区域形成清洁口，滚刷组件10的刷毛能够从清洁口处伸出，且刷毛能够对待清洁面进行清扫处理，如待清洁面可为地面，这样，刷毛能够将地面上的杂物、毛发等扫起，且配合吸尘器的吸尘组件对扬起的杂物、毛发进行吸纳、收置，从而实现地面的清洁的作用。
本申请实施例提供了一种滚刷组件，结合图1和图2a所示，该滚刷组件10包括滚筒2、第一毛刷组件3和传动装置4。滚筒2内部设有沿轴向延伸的空腔21，需要说明的是，本申请实施例中的滚筒2可以是圆筒形及棱柱形等规则的筒状结构，滚筒2还可以是不规则的筒状结构，本申请实施例不限定滚筒2的具体形状，只要滚筒2内的空腔21在滚筒2的轴向延伸即可。在滚筒2为规则圆柱状结构的情况下，滚筒2的轴向表示的是滚筒2的对称轴的延伸方向；在滚筒2为不规则结构的情况下，滚筒2的轴向可以近似认为是长度延伸方向。如图2a所示，滚筒2设有与空腔21连通的开口22，也就是说，开口22能够连通空腔21的内外两侧。
如图2a所示，第一毛刷组件3沿轴向延伸并在滚筒2的周向上位于开口22内，需要说明的是，第一毛刷组件3沿轴向(图2a所示x方向)延伸表示的是第一毛刷组件3中的主要组成部分沿轴向延伸，使得第一毛刷组件3的整体结构大致沿轴向延伸，并不表示第一毛刷组件3的所有结构均沿轴向延伸。第一毛刷组件3在周向上位于开口22内，可以理解为，沿着环绕滚筒2的轴线的方向看，第一毛刷组件3在开口22的边缘内，也就是开口22的边缘限定了第一毛刷组件的周向位置，使其不能相对滚筒2周向转动或者周向转动幅度受到限制；但是第一毛刷组件3相对滚筒2在径向可活动，即相对于滚筒2可以向外和向内运动以实现第一毛刷组件3相 对于开口22的伸缩运动。
如图2a所示，传动装置4至少部分在第一方向(图2a所示垂直于x方向的任意方向)上突出于滚筒2，第一方向与轴向(图2a所示x方向)呈设定夹角，该夹角可以是锐角、钝角或直角，但该夹角不能为零度，其中，第一方向并不限定是某一条直线的方向，可以是一组与轴向呈设定夹角的方向，也可以是一组垂直于轴向的方向。本申请实施例不限定第一方向的具体角度，通过限定第一方向与轴向的关系，以用于限定传动装置4与滚筒2在周向上的关系，也就是说，传动装置4在滚筒2的径向上凸出滚筒2，而不是在滚筒2的轴向凸出滚筒2，有利于用户对传动装置4进行施力。传动装置4部分可伸入到空腔21内，使得传动装置4与第一毛刷组件3连接，通过传动装置4驱动第一毛刷组件3在径向往复运动，径向表示的是内外方向，与轴向垂直。也就是说，第一毛刷组件3在径向运动的过程中，第一毛刷组件3的至少部分可相对开口22突出所述滚筒2的外表面，第一毛刷组件3也可完全收缩至空腔21内。
本申请实施例提供了一种滚刷组件，该滚刷组件包括滚筒、第一毛刷组件和传动装置，滚筒内部设有沿轴向延伸的空腔和与空腔连通的开口，第一毛刷组件沿轴向延伸且在滚筒的周向上位于开口内，驱动装置可带动第一毛刷组件在径向往复运动。其中，传动装置至少部分在第一方向上突出滚筒，第一方向垂直于轴向。本申请实施例通过将传动装置在垂直于轴向的方向上突出滚筒设置，那么用户可以通过作用于垂直轴向的力而转化成轴向的力而并带动第一毛刷组件实现第一毛刷组件在径向上的伸缩。本申请实施例可以通过脚踩的方式施加垂直于轴向的力，实现第一毛刷组件的两个工作状态的切换，切换方式简单，提高了用户使用的便捷度。
在一些实施例中，结合图2a和图3所示，传动装置4包括踏板机构41和伸缩机构42。如图2a所示，踏板机构41至少部分位于空腔21外。其中， 踏板机构41可以分为两个部分，其中一部分在第一方向(垂直于x方向的任意方向)上突出于滚筒2，另一部分沿轴向(图2a所示x方向)延伸。需要说明的是，第一方向用于表示滚筒2的径向，当然，滚筒2的径向并不限定是某一条直线的方向，而可以是一组垂直于滚筒轴向的方向，该径向可以是垂直于轴向的任意平面上的任意直线。可以理解的是，本申请实施例所述的踏板机构41部分在第一方向突出于滚筒表示的是踏板机构41在径向上位于空腔外侧，且踏板机构41并非在滚筒2的轴向上突出滚筒2。踏板机构41的另一部分沿轴向延伸，本申请实施例不限定沿轴向延伸的另一部分踏板机构41与空腔21的位置关系，该部分的踏板机构41可位于空腔21内，也可位于空腔21外，还可以是部分位于空腔21内，部分位于空腔21外。
如图3所示，伸缩机构42位于空腔21内。且伸缩机构42沿轴向(图3所示左右方向)延伸，需要说明的是，伸缩机构42中可包括多个部件，本申请实施例中所描述的伸缩机构42沿轴向延伸是指伸缩机构42中的主要部件或者整体沿轴向延伸，并非表示伸缩机构42中的所有部件均需要沿轴向延伸。伸缩机构42用于随踏板机构41的运动而在轴向(图3所示左右方向)运动，可以理解的是，结合图2a，踏板机构41至少部分在第一方向突出于滚筒2，踏板机构41中突出于滚筒2的部分可用于接收外部的驱动力(例如用户脚踩在踏板机构上的压力)，踏板机构41可以将驱动力传递至伸缩机构42，由于踏板机构41并非沿轴向延伸，故踏板机构41传递的驱动力非轴向的力，踏板机构41将非轴向的驱动力转化为轴向的作用力，再将轴向的作用力传递至伸缩机构42。伸缩机构42可以将沿轴向的作用力转化成径向的驱动力，伸缩机构42与第一毛刷组件3连接，从而伸缩机构42驱动第一毛刷组件3在径向(图3所示上下方向)上运动。
本申请实施例通过将传动装置设置为踏板机构和伸缩机构，踏板机构 能够将第一方向也就是滚筒径向的作用力转化为滚筒轴向的作用力，带动伸缩机构在轴向上运动，伸缩机构能够将轴向的作用力转化为径向的作用力，从而带动第一毛刷组件相对滚筒在径向运动，传动的结构简单，且传动方式可靠。
在一些实施例中，如图2a所示，踏板机构41包括第一子机构411和第二子机构412。第一子机构411延伸至踏板机构41的第一端413，第一端413表示的是踏板机构41中距离空腔21较远的区域。第一子机构411可在第一方向(滚筒2的径向)上平动，第一子机构411位于空腔21外，第一子机构411用于接收外部的驱动力，并在驱动力的作用下可相对滚筒2在第一方向上平行移动。如图2a所示，第二子机构412延伸至踏板机构41的第二端414，第二子机构412用于随第一子机构411的平动在轴向(图2a所示x方向)运动。需要说明的是，本申请实施例不限定第一子机构411和第二子机构412的具体形式，例如，第一子机构411可以是压力气泵装置，第二子机构412可以是伸缩装置，压力气泵装置与伸缩装置连接，压力气泵装置在受到沿第一方向的压力作用下，压力气泵装置内部的气体流动带动第二子机构在轴向上的运动。本申请实施例中的第一子机构411和第二子机构412的类型包括但不限于上述列举的形式，只要第一子机构411能够将第一方向的作用力传递至第二子机构412，且第二子机构412能够将第一方向的作用力转化为轴向(图2a所示x方向)上的作用力即可。
本申请实施例通过将踏板机构设置为第一子机构和第二子机构，第一子机构用于接收第一方向的作用力，第二子机构将第一方向的作用力转化为轴向的作用力。传动步骤清晰，且传动过程可靠，提高了踏板机构的踩踏流畅度，提高了用户切换滚刷组件中第一毛刷组件的工作状态的舒适度。
在一些实施例中，如图2a和图2b所示，第一子机构411包括压杆4111和第一弹性件4112。压杆4111从第一端413延伸至可与第二子机构412抵 靠的抵接端415；需要说明的是，压杆4111中的第一端413和抵接端415可视为压杆4111上的相对距离较远的两端，第一端413远离空腔21，抵接端415相对第一端413靠近空腔21。压杆4111可以是规则的结构，也可以是不规则的结构。第一弹性件4112抵接在压杆4111在第一方向上靠近滚筒2的一侧(图2b所示z方向的下侧)，本申请实施例中的第一方向表示滚筒2的径向，可以是图2b所示的z方向，也可以是图2b所示y方向。在滚刷组件10的正常使用状态下，第一子机构411具有相对的两侧，其中一侧(图2b所示z方向的下侧)靠近滚筒2，另外一侧(图2b所示z方向的上侧)背离滚筒2，第一弹性件4112的一端(图2b所示z方向的上端)与压杆4111靠近滚筒2的一侧(图2b所示z方向的下侧)抵靠，其中，第一弹性件4112可与压杆4111有连接关系，也可以没有连接关系，只要第一弹性件4112能够带动压杆4111在z方向向上运动即可。第一弹性件4112的另一端(图2b所示z方向的下端)可与吸尘器的座体或其他部件相抵靠。第一弹性件4112在第一方向上(图2b所示z方向)可往复运动，其中，第一弹性件4112在自身的长度方向上可伸缩，通过将第一弹性件4112的长度方向沿第一方向(图2b所示z方向)设置，使得第一弹性件4112在受到压杆4111作用的第一方向的力的情况下，第一弹性件4112能够在第一方向形变，使得第一弹性件4112可带动压杆4111在第一方向上平动。需要说明的是，本申请实施例中第一弹性件4112包括但不限于本申请实施例所列举的弹簧及弹性体，只要第一弹性件4112受到外力的作用能够在第一方向往复运动即可。
如图2a和图2b所示，第二子机构412包括第一连杆4121和第二连杆4122。第一连杆4121一端(图2b所示x方向的左端)相对滚筒2在轴向(图2b所示x方向)上固定，需要说的是，第一连杆4121与滚筒2可以不具有直接连接关系，本申请实施例所述的第一连杆4121的一端相对滚筒 2在轴向上固定用于表示第一连杆4121与滚筒2在轴向上的相对位置状态，也就是说，滚筒2可以绕自身轴向(图2b所示x方向)转动，但滚筒2在轴向上的相对位置不改变。第一连杆4121的一端(图2b所示x方向的左端)可与吸尘器中除滚筒外的其他至少在轴向上固定的部件连接，从而使得第一连杆4121的一端相对滚筒2在轴向上固定。第一连杆4121的另一端(图2b所示x方向的右端)为铰接端416。第二连杆4122的一端(图2b所示x方向上第二连杆的左端)与第一连杆4121的铰接端416铰接，第二连杆4122的另一端(图2b所示x方向上第二连杆的右端)延伸至第二端414。压杆4111的抵接端415抵靠第一连杆4121的铰接端416，使得压杆4111的作用力能够通过抵接端415传递至第一连杆和第二连杆4122上。
在一些实施例中，如图2b所示，第一子机构411还包括脚踏件4113。脚踏件4113连接在压杆4111在第一方向(图2b中z方向)上远离滚筒2的一侧。脚踏件4113可设置为平板件，也可设置为表面带有凸部的部件，需要说明的是，脚踏件4113的延伸方向可与实际使用状态下的水平方向平行，脚踏件4113的延伸方向还可以相对实际使用状态的水平方向倾斜，本申请实施例不限定脚踏件4113的设置角度，只要脚踏件4113能够将外部的驱动力沿滚筒的径向传递至压杆4111即可。本申请实施例通过在压杆上设置脚踏件，能够增大用户脚部与踏板机构的受力面积，提高用户脚踏的舒适度。
在一些实施例中，结合图2a-图4所示，第二子机构412还包括顶杆4123和卡座4124。顶杆4123沿轴向延伸，顶杆4123一端(图4所示左端)与第二连杆4122的第二端414铰接。顶杆4123的另一端(图4所示右端)在轴向上的投影位于第一连杆4121和第二连杆4122之间。第一连杆4121的一端(图4所示右端)与卡座4124抵接，其中，抵接表示的是抵靠连接，可以理解为第一连杆4121的一端(图4所示右端)相对卡座4124固定， 第一连杆4121的另一端(图4所示左端)为铰接端416(参照图2b所示)。卡座4124设有沿轴向的盲孔4125，盲孔4125与空腔21连通，顶杆4123的另一端(图4所示右端)可在盲孔4125内轴向运动。如图2b所示，第二连杆4122可相对第一连杆4121转动，使得第二连杆4122与第一连杆4121之间的夹角变化，从而改变了第二连杆4122的第二端414在轴向(图2b所示x方向)上的位置，顶杆4123的一端(图4所示左端)与第二连杆4122的第二端414可转动地连接，故在第二端414在轴向上运动的情况下，第二端414可带动着顶杆4123沿轴向运动。由于顶杆4123的周向收到盲孔4125的限制，顶杆4123可以相对盲孔4125在轴向上运动，但是顶杆4123不能相对盲孔4125在径向上运动，顶杆4123可设置为刚性件，从而使得与顶杆4123连接的第二端414也只能跟随顶杆4123够沿着轴向运动。本申请实施例通过在第二子机构设置顶杆和卡座，将第二连杆中第二端的位移限定在同一条直线(轴线)上，提高了第二子机构传动的稳定性。
在一些实施例中，如图3所示，伸缩机构42包括定位组件421和移动组件422。定位组件421在轴向(图3所示左右方向)上靠近踏板机构的第二端414设置，定位组件421可在踏板机构的作用下沿轴向(图3所示左右方向)移动，并在轴向上的第一位置和第二位置定位。其中，第一位置的状态下，第一毛刷组件3部分凸出所述滚筒2的外表面；在第二位置的状态下，第一毛刷组件3完全收缩至空腔21内。移动组件422沿轴向延伸，且移动组件422的一端(图3所示右端)与定位组件421抵靠以随定位组件421沿轴向正向移动。需要说明的是，抵靠表示的是移动组件422的一端可与定位组件421之间有接触关系但没有连接关系，当然移动组件422与定位组件421之间也可以有连接关系。无论移动组件422与定位组件421之间是否有连接关系，只要移动组件422的一端与定位组件421的一端接触，定位组件421在轴向的正向(图3所示向左)运动即可带动移动组件 422在轴向上运动，或者移动组件422在轴向的负向(图3所示向右)运动即可带动定位组件421在轴向运动。在本申请实施例中，第一毛刷组件3与移动组件422可活动地连接，在移动组件422相对滚筒2在轴向上运动的情况下，移动组件422可相对第一毛刷组件3在径向的正向(沿图3所示轴向向左)运动，在此过程中，移动组件422挤压设置在移动组件422的远离定位组件421的第六端424(图3所示左端)和滚筒2之间的第二弹性件423；在定位组件421运动至第二位置的情况下，第二弹性件423的恢复作用力推动着移动组件422沿轴向反向(图3所示轴向向右)运动。
本申请实施例通过将伸缩机构设置为定位组件和移动组件，定位组件可以在轴向上的第一位置和第二位置定位，移动组件在定位组件的作用下能够分别在第一位置和第二位置的状态下固定，从而带动第一毛刷组件分别在伸出滚筒和收回滚筒两个状态下定位。
在一些实施例中，如图5所示，定位组件421包括轴承座4211、滑柱4212和按动键4213。结合图6所示，轴承座4211内部中空设置，轴承座4211在轴向(图6所示左右方向)上具有相对的第三端4211a和第四端4211b，第四端4211b相对第三端4211a靠近移动组件，轴承座4211的内壁4211c设有沿轴向(图6所示左右方向)延伸的第一凸起4211d，第一凸起4211d在周向上间隔设置，相邻第一凸起4211d之间形成第一滑槽4211e，第一凸起4211d靠近第四端4211b的一侧设有第一斜面4211f。其中，第一斜面4211f设置为凹面。
如图5所示，滑柱4212沿轴向(图5所示左右方向)延伸，且滑柱4212至少部分设置在轴承座4211内靠近第四端4211b的一侧，滑柱4212在轴向上可部分相对轴承座4211的第四端4211b凸起。滑柱4212在周向上间隔设置多个第二凸起4212a，第二凸起4212a靠近第三端4211a的一侧设有第二斜面4212b，在第一位置的状态下，第二凸起4212a的第二斜面4212b 可卡接在轴承座4211的第一斜面4211f；在第二位置的状态下，第二凸起4212a可滑动至轴承座4211的第一滑槽4211e内。
如图5所示，按动键4213沿轴向(图5所示左右方向)延伸且至少部分设置在轴承座4211内相对滑柱4212靠近第三端4211a的一侧，按动键4213靠近第四端4211b的一端设有第三斜面4213a，第三斜面4213a可与第二斜面4212b配合，按动键4213可通过第三斜面4213a带动第二斜面4212b在轴向上运动，以带动第二斜面4212b轮流与第一斜面4211f、第一滑槽4211e配合。按动键4213在周向上间隔设置多个第三凸起4213b，按动键4213与轴承座4211之间通过第三凸起4213b与第一滑槽4211e之间滑动配合，按动键4213相对轴承座4211在周向上固定，第三凸起4213b可相对第一滑槽4211e在轴向(图5所示左右方向)上滑动，以带动第二凸起4212a上的第二斜面4212b轮流与第一滑槽4211e和第一斜面4211f配合。
图7所示为传动装置在轴向上的第一位置的状态示意图，图8为踏板机构受外力作用的状态示意，图9为传动装置在轴向上的第二位置的状态示意图。在传动装置从第二位置切换到第一位置的过程中，结合图3和图8所示，在压杆4111受到外力的作用下，压杆4111沿第一方向朝靠近滚筒2轴线的方向运动，在此过程中，第一弹性件4112受压杆4111的作用力挤压变形；第一连杆4121的铰接端416受到压杆4111作用的朝靠近轴线方向的力，第一连杆4121的一端在轴向相对滚筒2固定，第二连杆4122相对第一连杆4121的铰接端416转动，使得第一连杆4121与第二连杆4122之间的夹角θ增大，使第二连杆4122的第二端414推动按动键4213朝正向(图8所示向左)运动，按动键4213的第三斜面4213a与滑柱4212的第二斜面4212b配合，使得第三斜面4213a推动第二斜面4212b沿轴向的正向(图8所示向左)运动；如图7所示，直到第二斜面4212b运动到轴向上轴承座4211中第一斜面4211f所在的位置。第二斜面4212b与第一斜面 4211f配合，压杆上的外力消失，使得第二斜面4212b限位在第一斜面4211f处，实现定位组件在第一位置的定位。
如图7所示，在第一位置的状态下，第一连杆4121的铰接端416不受到压杆的作用力，第一连杆4121恢复到与第二连杆4122之间的夹角θ呈锐角的状态；第二斜面4212b限位在第一斜面4211f的凹陷处，轴承座4211抵靠着第二斜面4212b，使得滑柱4212不会向轴向的反向(图8所示向右)移动，从而实现定位组件在第一位置的定位；其中，踏板机构所受的外力可以是瞬时作用力，也就是说，在第二斜面4212b与第一斜面4211f配合之后，外力即消失，第一弹性件4112的恢复作用力带动着压杆4111在第一方向朝向远离滚筒2的方向运动，第一连杆4121的铰接端416所受的压杆4111的作用力减小，直到第一连杆4121的铰接端416不受到压杆4111的作用力，在此过程中，压杆会带动着第二连杆4122的第二端414朝靠近第一连杆4121的方向运动，第二连杆4122可相对第一连杆4121恢复到初始的位置，第一连杆4121与第二连杆4122之间的夹角θ逐渐减小至初始的角度。在此过程中，按动键4213可跟随第二连杆4122的第二端414向轴向的负向(图7所示向右)运动。在不受轴向力的作用下，第二斜面4212b始终与第一斜面4211f配合，使得滑柱4212始终保持在轴向的第一位置处。
图9所示为定位组件421在轴向上的第二位置。在定位组件从第一位置切换到第二位置的过程中，传动装置依次经过图7、图8到图9的状态。图7为定位组件在第一位置的状态，滑柱4212的第二斜面4212b抵靠轴承座4211的第一斜面4211f。如图8所示，用户朝压杆施加外力，压杆将作用力传递至第一连杆4121的铰接端416，第二连杆4122相对第一连杆4121转动，使得第二连杆4122的第二端414沿轴向正向(图8所示向左)运动，第二端414推动按动键4213和滑柱4212朝轴向正向运动，直到滑柱4212中第二凸起4212a的第二斜面4212b沿着第一斜面4211f移动至相邻的第一 滑槽4211e内，此时，如图9所示，外力消失，压杆带动第二端414沿轴向负向运动，按动键4213和滑柱4212跟随第二端414往轴向的负向(图9所示向右)运动，直到按动键4213运动至轴向上的第二位置，按动键4213和滑柱4212停止往轴向的负向运动，图9所示为按动键4213和滑柱4212均位于第二位置的状态示意。
在一些实施例中，如图10所示，第一毛刷组件3包括毛刷架31和凸块32。如图3所示毛刷架31设置在空腔21内，且毛刷架31沿轴向延伸，毛刷架31靠近开口22的一侧(图3所示上侧)设有第一刷毛311。一些实施例中如图10所示，第一刷毛311可呈v型排布在滚筒2上，如图11所示，滚筒2上的开口22也可设置为与第一刷毛适应的v形开口22。本申请实施例不限定第一毛刷组件中第一刷毛311的材质和硬度。凸块32设置在毛刷架31远离开口22的一侧(图10所示下侧)，如图3所示，凸块32与移动组件422可活动地连接。
移动组件422包括支架4221。支架4221沿轴向延伸，支架4221表面设有第二滑槽4221a，凸块32可伸入至第二滑槽4221a内，并沿着第二滑槽4221a移动。支架4221的一端(图3所示左端)与第二弹性件423抵靠，支架4221的第五端425(图3所示右端)与滑柱4212抵靠，滑柱4212可推动支架4221沿轴向的正向(图3所示向左)运动，在运动过程中支架4221挤压第二弹性件423，第二弹性件423挤压变形。在滑柱4212沿轴向的负向(图3所示向右)运动的情况下，第二弹性件423恢复形变，第二弹性件423的恢复力可带动着支架4221沿轴向的负向运动。在支架4221沿轴向往复运动的过程中，凸块32可沿着支架4221上的第二滑槽4221a沿径向运动，从而实现了第一毛刷组件3在径向上的伸缩。本申请实施例通过采用凸块的形式与第二滑槽连接，降低了第一毛刷组件与移动组件配合的难度。
结合图3所示，以下对第二弹性件423、支架4221及滚筒2在不同状态的相互关系进行说明：
在支架4221沿轴向往正向(图3所示向左)运动的情况下，支架4221的第六端424将作用力传递至第二弹性件423，由于滚筒2在轴向上的位置固定，故第二弹性件423可在作用力的挤压下收缩，使得支架4221的第六端424朝靠近第二弹性件423与滚筒2连接的一端运动。在支架4221上作用力消失的情况下，第二弹性件423的恢复力会带动着支架沿轴向的负向(图3所示向右)运动。
需要说明的是，本申请实施例不限定第二弹性件423的具体结构，第二弹性件可以是沿轴向延伸的弹簧及弹性球等具有可恢复形变能力的结构。
在一些实施例中，如图3所示，第二滑槽4221a的延伸方向与轴向呈锐角设置，需要说明的是，第二滑槽4221a的延伸形态可以是直线滑槽，也可以是曲线滑槽，但是，本申请实施例中的第二滑槽4221a无论是采用何种形态延伸，第二滑槽4221a均具有一个大致的延伸方向，该延伸方向可以是采用第二滑槽4221a在延伸方向的相对两端的连线的方向来表示。本申请实施例中的第二滑槽4221a的延伸方向与轴向呈锐角表示的是，第二滑槽4221a的延伸方向在轴向和径向均有延伸，而不是第二滑槽4221a的延伸方向与轴向垂直，也可以理解为，第二滑槽4221a相对两端在滚筒2的轴向(图3所示的左右方向)和径向(图3所示的上下方向)上均间隔，第一毛刷组件可沿第二滑槽4221a移动以在径向伸缩。其中，第二滑槽4221a的长度延伸方向上具有相对的两端，该相对的两端在滚筒2的轴向(图3所示左右方向)和径向(图3所示上下方向)均间隔，从而使得第一毛刷组件3沿第二滑槽4221a运动的过程中，第一毛刷组件可相对滑槽在轴向和径向均能够移动。本申请实施例可通过限制第一毛刷组件在轴向上的位 置，在移动组件沿轴向往复运动的过程中，第一毛刷组件可相对第二滑槽在轴向和径向运动，从而实现了第一毛刷组件在凸出开口和收缩至空腔内的两种状态的自动切换，提高了滚刷组件两种状态切换的流畅度，提高了用户的体验度。
结合图3所示，以下对第一毛刷组件的运动过程进行说明：
在第一位置的状态下，第一毛刷组件3中的第一刷毛311在径向(图3所示上下方向)上凸出开口22，支架4221设有四个滑槽4221a，从左往右的第一个滑槽4221a和第四个滑槽4221a的延伸形态相同，均是从左上延伸至右下，位于下方的第一毛刷组件3与上述两个滑槽4221a连接；从左往右的第二个滑槽4221a和第四个滑槽4221a的延伸形态相同，均是从左下延伸至右上，位于上方的第一毛刷组件3与上述两个滑槽4221a连接。
在第一毛刷组件3从第一位置切换到第二位置的过程中，支架4221沿轴向负向(图3所示向右)运动，支架4221上的滑槽4221a也向轴向的负向(图3所示向右运动)，第一毛刷组件3沿着滑槽4221a的延伸方向运动，由于上方的第一毛刷组件3对应滑槽4221a为左下方延伸至右上方，在支架4221运动的过程中，使得上方的第一毛刷组件3相对滑槽4221a往轴向的正向(图3所示向左)和相对滚筒2往径向靠近轴线的方向(图3所示向下)运动；由于下方的第一毛刷组件3对应滑槽4221a为左上方延伸至右下方，在支架4221运动的过程中，下方的第一毛刷组件3相对滑槽4221a往轴向的正向(图3所示向左)和相对滚筒2往径向上靠近轴线的方向(图3所示向上)运动，使得上方和下方的第一毛刷组件3均收缩在空腔21内，以达到第二位置的状态。
在一些实施例中，如图12所示，第二滑槽4221a沿平滑曲线延伸至靠近支架4221的径向边缘处。图12中第二滑槽4221a从支架4221的左下方延伸至右上方的支架4221边缘处。其中，平滑曲线表示的是第二滑槽4221a 的形状呈平滑的凹凸曲线延伸，第二滑槽4221a的延伸方向可设置多个凹部426，在凸块32沿第二滑槽4221a运动的过程中，凸块32在不受外力的作用下可稳定的限位在凹部426的位置处。本申请实施例通过将第二滑槽设置为平滑曲线，有利于提高支架在第一位置和第二位置与凸块限位的稳定性。
在一些实施例中，如图12所示，第二滑槽4221a在轴向(图12所示点划线方向)上间隔设置多个，结合如图10所示，第一毛刷组件3设有多个凸块32，凸块32与第二滑槽4221a一一对应地活动连接。需要说明的是，本申请实施例中，同一第一毛刷组件3上的凸块32所对应的第二滑槽4221a均沿相同的方向延伸。其中，第二滑槽4221a除了可以像图12所示的从支架4221的左下往右上方向延伸的形态，还可以设置为从左上向右下延伸的形态。同一第一毛刷组件3上的凸块32所对应的第二滑槽4221a均沿相同的方向延伸指的是同一第一毛刷组件3上的所有凸块32所对应的第二滑槽4221a均从左上延伸至右下，或均从左下延伸至右上。以图12所示的第二滑槽形态为例，在支架4221沿轴向的正向(图12所示向左)运动的过程中，同一第一毛刷组件3上的所有凸块32均沿第二滑槽4221a向图12所示右上运动，使得第一毛刷组件3相对滚筒2沿图12所示的径向向上运动；或者，在支架4221沿轴向的负向(图12所示向右)运动的过程中，同一第一毛刷组件3上的所有凸块32均沿第二滑槽4221a向图12所示左下运动，使得第一毛刷组件3相对滚筒2沿图12所示的径向向下运动。本申请实施例中第二滑槽的延伸形态及支架的运动方向共同影响着第一毛刷组件的伸缩状态。
本申请实施例通过将支架上设置多个第二滑槽，并在第一毛刷组件上设置多个凸块，第二滑槽与凸块一一配合，增加了第一毛刷组件与支架连接的凸块数量，提高了第一毛刷组件与凸块连接的稳定性。
在一些实施例中，如图12所示，支架4221具有相背设置的第一表面427和第二表面428，第一表面427与第二表面428均设有第二滑槽4221a，其中，第一表面427为正向图12所示纸面方向的表面，第二表面428为背离纸面方向的表面，图12中将第一表面427的第二滑槽4221a用实线示意，将第二表面428的第二滑槽4221a用虚线示意。在本申请实施例中，轴向(图12所示点划线方向)上第一表面427和第二表面428均间隔设置多个第二滑槽4221a，其中，第一表面427上的第二滑槽4221a和第二表面428上的第二滑槽4221a在径向上的投影可以重叠，也可以交错。图12实施例中的第一表面427的第二滑槽4221a和第二表面428的第二滑槽4221a在轴向(图12所示点划线方向)上交错设置。如图12所示，毛刷架31上设有多个凸块32，结合图10所示，毛刷架31上的凸块32设置有两排，其中，凸块32包括延伸部321和凸起部322，延伸部321的一端与毛刷架31连接，凸起部322相对所述延伸部321凸起。在一些实施例中，毛刷架31上设置有两排凸块32，两排毛刷架31上凸块32中的凸起部322相对设置，其中毛刷架31上的一排凸块32中的凸起部322与第一表面427上的第二滑槽连接，另一排凸块32中的凸起部322与第二表面428上的第二滑槽4221a连接。在第一毛刷组件3与移动组件422配合的状态下，两排凸块32分别位于支架4221的相对两侧。
本申请实施例通过将第一毛刷组件上的凸块设置为两排，且支架的第一表面和第二表面均设有第二滑槽，使得毛刷架从支架的相对两侧与支架配合，使得支架两侧受力均匀，提高支架与毛刷架配合的稳固性，并且提高毛刷架相对支架运动的稳定性。
在一些实施例中，如图13所示，第一毛刷组件3设置为两个(图13所示的上下两个)，对应的滚筒上也设置有两个与第一毛刷组件3对应的开口。支架4221上与同一第一毛刷组件3配合的第二滑槽4221a的形态一致； 支架4221上与不同第一毛刷组件3配合的第二滑槽4221a的形态相反。每个第一毛刷组件3上设有两排凸块32，其中一排凸块32与支架4221的第一表面427上的第二滑槽4221a配合，另一排凸块32与支架4221的第二表面428上的第二滑槽4221a配合，两个第一毛刷组件3上均设置为两排凸块32的形式，支架4221上的第二滑槽4221a交替设置，使得两个第一毛刷组件3的运动互不干扰。如图13所示实施例，可分为上下两个第一毛刷组件3，上方的第一毛刷组件3所对应的支架4221上的第二滑槽4221a形态为从左下方延伸至右上方，图13中仅示意出了第一表面427上第二滑槽4221a的延伸形态，第二表面428上与上方的第一毛刷组件3所对应的第二滑槽4221a的延伸形态也是从左下方延伸至右上方。使得支架4221沿轴向的正向运动的情况下，上方的第一毛刷组件3的凸块32能够沿第二滑槽4221a从左下运动至右上，从而实现上方的第一毛刷组件3在径向上远离支架4221并靠近滚筒的开口方向运动(图13所示向上运动)。下方的第一毛刷组件3所对应的支架4221上的第二滑槽4221a形态为从左上方延伸至右下方，图13中仅示意出了第一表面427上第二滑槽4221a的延伸形态，第二表面428上与下方的第一毛刷组件3所对应的第二滑槽4221a的延伸形态也是从左上方延伸至右下方。使得支架4221沿轴向的正向运动的情况下，下方的第一毛刷组件3的凸块32能够沿第二滑槽4221a从左上运动至右下，从而实现下方的第一毛刷组件3在径向上远离支架并靠近滚筒的开口的方向运动(图13所示向下运动)。
以下结合图14和图15对本申请实施例中移动组件带动第一毛刷组件的伸缩原理进行说明：
图14所示为第一毛刷组件3位于第一位置的状态示意图，在第一位置的状态下，第一毛刷组件3中的第一刷毛311在径向(图14所示上下方向)上凸出开口22，支架4221的第一表面427设有四个第二滑槽4221a，从左 往右的第一个第二滑槽4221a和第四个第二滑槽4221a的延伸形态相同，均是从左上延伸至右下，位于下方的第一毛刷组件3与上述两个第二滑槽4221a连接；从左往右的第二个第二滑槽4221a和第四个第二滑槽4221a的延伸形态相同，均是从左下延伸至右上，位于上方的第一毛刷组件3与上述两个第二滑槽4221a连接。
图15为第一毛刷组件3位于第二位置的状态示意图，在第二位置的状态下，第一毛刷组件3中的第一刷毛311为径向上收缩在空腔21内，图15中第二滑槽4221a和凸块32的布设方式与图14一致，故不再赘述。在支架4221沿轴向负向(图14所示向右)运动的情况下，
在第一毛刷组件3从第一位置切换到第二位置的过程中(参照图14切换至图15的过程)，支架4221沿轴向负向(图14所示向右)运动，支架4221上的第二滑槽也向轴向的负向(图14所示向右运动)，第一毛刷组件3沿着第二滑槽4221a的延伸方向运动，由于上方的第一毛刷组件3对应第二滑槽4221a为左下方延伸至右上方，在支架4221运动的过程中，使得上方的第一毛刷组件3相对第二滑槽4221a往轴向的正向(图14所示向左)和相对滚筒2往径向靠近轴线的方向(图14所示向下)运动；由于下方的第一毛刷组件3对应第二滑槽4221a为左上方延伸至右下方，在支架4221运动的过程中，下方的第一毛刷组件3相对第二滑槽4221a往轴向的正向(图14所示向左)和相对滚筒2往径向上靠近轴线的方向(图14所示向上)运动，使得上方和下方的第一毛刷组件3均收缩在空腔21内，以达到第二位置的状态。
在第一毛刷组件3从第二位置切换到第一位置的过程中(参照图15切换至图14的过程)，支架4221上的第二滑槽也向轴向的正向(图15所示向左运动)，第一毛刷组件3沿着第二滑槽4221a的延伸方向运动，由于上方的第一毛刷组件3对应第二滑槽4221a为左下方延伸至右上方，在支架 4221运动的过程中，使得上方的第一毛刷组件3相对第二滑槽4221a往轴向的负向(图15所示向右)和相对滚筒2往径向远离轴线的方向(图15所示向上)运动；由于下方的第一毛刷组件3对应第二滑槽4221a为左上方延伸至右下方，在支架4221运动的过程中，下方的第一毛刷组件3相对第二滑槽4221a往轴向的负向(图15所示向右)和相对滚筒2往径向上远离轴线的方向(图15所示向下)运动，使得上方和下方的第一毛刷组件3均凸出开口22，以达到第一位置的状态。
本申请实施例通过将滚刷组件设置有两组第一毛刷组件，在支架的一次运动过程中，可以同时带动两个第一毛刷组件同步运动，增加了第一毛刷组件的数量，提高了滚刷组件在第一位置的状态下与地板的接触面积，从而能够提高清洁的效率。
在一些实施例中，滚刷组件10还包括第二刷毛。第二刷毛沿轴向固定在滚筒2的表面；其中，在第一毛刷组件3凸出开口22的状态下，第一毛刷组件3在滚筒2的径向上凸出第二刷毛。在一些实施例中，第一毛刷组件3中的第一刷毛311可以是硬毛，第二刷毛可以是软毛。其中硬毛的毛体为硬质材质，该硬质材质的第一毛刷可以用来清洁地毯，而软毛的毛体为软质材质，该软质材质的第二刷毛可以用来清洁地板。而第一刷毛和第二刷毛两种毛刷结构是可以在滚刷上相对切换的，其中，第二刷毛为固定在滚筒2表面的固定结构，与该第二刷毛相对应的，第一刷毛311活动装配在空腔内，所以第一刷毛311可以通过在空腔21内伸出或回缩而调整其相对于第二刷毛的径向位置。
本申请实施例提供一种清洁设备，如图1所示，该清洁设备包括：根据上述任一实施例所述的滚刷组件10、座体6及驱动装置7，滚刷组件10在轴向的两端与座体6可转动的连接，驱动装置7用于驱动滚刷组件10相对座体6绕轴向转动。在清洁状态下，驱动装置7可带动滚刷组件10绕自 身轴向转动，滚刷组件10上的刷毛能够跟随滚筒绕轴向运动，以实现与地板的持续接触和摩擦，带动地板的灰尘扬起，再通过吸尘部件将扬起的灰尘吸附至清洁设备内，从而达到清洁的目的，本申请所描述的滚刷组件在清洁设备中的用途不限于上述方式。
以上所述，仅为本申请的较佳实施例而已，并非用于限定本申请的保护范围。
