本申请涉及清洁用具技术领域，具体涉及一种滚刷；另外，本申请还涉及一种采用前述滚刷的吸尘器。
背景技术
为使待清洁面中隐藏的污渍更好地被清除，一些吸尘器的吸尘口前侧设置有滚刷；滚刷转动而清扫或者梳理待清洁面，将隐藏在待清洁面缝隙中的污渍扫出，并将污渍推送到吸尘口区域。
日常生活经验可知，吸尘器可能被用于清扫不同类型的待清洁面；以家庭用吸尘器为例，其可能被用于清洁地毯面、陶瓷面或者地板面；因为不同待清洁面的表面特性、表面粗糙特性不同，为达到最优的清洁效果，滚刷的刮扫件应当根据待清洁面的特性被设置成不同的长度。
公开号为CN107252276A、发明名称为《一种滚刷及其吸尘器》的中国发明专利申请公开了一种可以改变刷毛(即前述刮扫件)长度的滚刷；参见前述专利申请的公开文本可知，其中的滚刷主要包括滚轴体和刷毛件；在滚轴体表面设置有装配槽，卡接槽包括沿滚轴体径向分布的多个卡接槽；刷毛件包括刷毛和基座，基座可以拆卸地卡接在多个卡接槽之一中；通过更换基座设置在不同的装配槽中，可以改变刷毛的可用长度。结合附图可知，滚轴体上设置多个装配槽，滚刷包括与各个装配槽配合的刷毛件。
但结合前述中国发明专利申请的结构可知，为了改变各个刷毛件中刷毛的可用长度，需要分别将各个刷毛件从对应的卡接槽取出再安装在另一卡接槽中，拆装刷毛件耗时耗力。

具体实施方式
下面结合附图和实施例对本申请作进一步的详细说明。可以理解的是，下文所描述的具体实施例仅仅用于解释相关发明，而非对该发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与有关发明相关的部分。
请参见各个附图，具体参见图1和图4-图7，本实施例提供的滚刷包括刷辊11和芯轴件12。
刷辊11呈圆筒状，其周侧壁围成一内腔111；在刷辊11的周侧壁上设置有贯通孔112；贯通孔112由刷辊11的内周侧面延伸至刷辊11的外周侧面，与刷辊11的内腔111连通。
芯轴件12包括芯轴本体121和刮条122。本实施例中，芯轴本体121大体呈圆柱形状，并且截面尺寸小于内腔111的截面尺寸，以保证可以插入到内腔111中。刮条122设置在芯轴件12的周侧面上、凸出于芯轴本体121的周侧面。
芯轴件12设置到刷辊11的内腔111内后，芯轴本体121与刷辊11的内周侧壁之间具有一定的间隙，并且芯轴本体121相对于刷辊11可转动。
如图5和图6，刮条122的自由端插入到刷辊11的贯通孔112中，并且在特定状态时伸出刷辊11的外表面外侧(也就是伸出贯通孔112)；因为芯轴本体121相对刷辊11可转动，并且刮条122与芯轴本体121一体连接，所以当芯轴本体121转动时，刮条122伸出刷辊11的长度可以随芯轴本体121相对于刷辊11的转动而改变。
本实施例中，刮条122采用橡胶或者树脂材料制成，具有一定弹性和形变性(应当注意，刮条122材质是本领域的公知技术)，并且刮条122的厚度略大于贯通孔112对应维度上的宽度。刮条122插入到贯通孔112后，可以被贯通孔112夹紧、相对于刷辊11固定。当滚刷转动时，在贯通孔112夹紧力的作用下，刷辊11和芯轴件12一体地可转动；并且，在滚刷转动时，刮条122伸出贯通孔112的长度并不变化。
当滚刷用于清扫不同粗糙度或者不同特性的待清扫面时，采用较大的外力作用在芯轴 本体121上、使芯轴本体121相对于刷辊11转动，刮条122相对于贯通孔112移动、伸出刷辊11表面的长度也就随之变化。
应当注意，本实施例中刮条122挺度较好，因此不论芯轴本体121正反转，刮条122均可以相对贯通孔112移动；在其他实施例中，如果刮条122挺度较差，可以通过从刷辊11外拉扯刮条122的形式、使芯轴本体121被动转动，增加刮条122伸出刷辊11外周侧面的长度；而通过转动芯轴本体121(按照图示方向的相反方向)，可以使刮条122伸出刷辊11外周侧面的长度变短。
本实施例提供的滚刷，可以根据待清洁面的特性设置刮条122伸出刷辊11外周面的长度，使滚刷能够适应不同应用需求。并且，刮条122伸出长度的改变由转动芯轴本体121或外力拉扯刮条122实现，操作较为方便、具有易用性。
如各个附图，本实施例中，刷辊11的内周侧面和芯轴本体121的外周侧面均设置为圆柱面；而在其他实施例中，刷辊11的内周侧面和芯轴本体121的外周侧面也可以设置成其他截面形状，只要保证影响芯轴本体121在正常范围的转动即可。
在本实施例中，在滚刷正常使用时，芯轴件12和刷辊11之间的相对固定通过贯通孔112夹紧刮条122实现。在其他实施例中，也可以为滚刷设置连接固定接件，连接固定件可以与芯轴件12和刷辊11固定连接，并可以相对芯轴件12和刷辊11可拆卸。当需要调整刮条122伸出刷辊11的长度时，可以拆下连接固定件，使芯轴本体121相对刷辊11可转动；而使用滚刷时，则再安装上连接固定件。下文中，将对一种可能形式的连接固定件做具体分析。
前述实施例中，与芯轴本体121连接的、伸出贯通孔112外圆周面的刮扫件为刮条122；在其他实施例中，刮扫件也可以是刷毛，并且刷毛并不限于前文提及的树脂类材料，其也可以是纤维类材料的刷毛。
当然，在刮扫件为刷毛的情况下，优选在滚刷中设置连接固定件，保证滚刷使用时刷毛伸出刷辊11的长度改变较小。
请参见图5，本实施例提供的滚刷中，设置在刷辊11上的贯通孔112为长孔，并且贯通孔112在刷辊11的第一轴端形成开口113(即本实施例提供的贯通孔112实际为贯通长槽)。可想到，实际应用中，芯轴本体121插入到内腔111时，刮条122可以通过开口113快速地插入到贯通孔112中，也就是芯轴件12的安装拆卸均较为方便。
当然，在其他实施例中，也可以沿刷辊11轴向方向设置多个贯通孔112；安装芯轴件12时，先将芯轴件12插入到刷辊11的内腔111中，再将刮条122插入到对应的贯通孔112中。但是，这样的结构使得滚刷的安装、拆卸非常复杂，实际应用价值相对较小。
请继续参见图5，并参见图6。本实施例提供的滚刷中，设置在刷辊11上的贯通孔112为螺旋状的长孔；即，贯通孔112大体沿滚轴的轴向的方向延伸时，相对于刷辊11的母线形成大于0度的第一偏转夹角。
对应的，设置在芯轴本体121周侧面的刮条122为螺旋状的刮条122，刮条122与芯轴本体121的母线形成大于0度的第二偏转夹角。第一偏转夹角和第二偏转夹角的角度相同，并且偏转方向相同(也就是贯通孔112的旋向和刮条122的旋向相同)。
以下，结合附图1说明将贯通孔112和刮条122设置成螺旋状的优点。请参见附图1，滚刷的第二轴端与驱动电机的输出轴19连接。因为结构和尺寸的限制，在滚刷的第二轴端侧设置驱动电机后，此处设置吸尘口的可能性较小。而本实施例中，通过将贯通孔112和刮扫件设置成螺旋状，可以通过螺旋状将靠近第二轴端侧的尘污推送到第一轴端侧，无需将吸尘器的吸尘口设置在靠近在第一轴端的位置。
应当注意，如果将贯通孔112和刮条122设置成螺旋状的结构，滚刷应当按照各图所示的方向旋转，即刮条122靠近第二轴端的部分先接触待清洁面，而靠近第一轴端的部分最后接触待清洁面。
还应用注意，本实施例中，贯通孔112的延伸方向和刷辊11的母线形成第一偏转角的情况下，如果将贯通孔112铺展到一个平面上，贯通孔112本身为一直线孔；但实际应用中，贯通孔112与刷辊11母线之间的夹角也可以不是固定的第一偏转角，而是在不同位置处相对于滚刷母线的偏转角度不相同；也就是说，如果将贯通孔112铺展到一个平面上，贯通孔112可以不是直线孔。
另外，在其他实施例中，第一偏转角和第二偏转角不完全相同也不影响实现前述功能；只是可能会造成刮条122容易被卡滞在贯通孔112内、不便于旋转芯轴本体121。
如图1-图6所示，本实施例中，刷辊11中设置有四个均匀分布的贯通孔112，相邻的贯通孔112形成的扇形柱面的夹角为90度；芯轴件12上设置有与各个贯通孔112对应的刮条122。此外，本实施例中，第一偏转角等于相邻的两个贯通孔112之间扇形柱面对应的圆心角，即第一偏转角为90度。
在使用滚刷时，应当保证前一刮条122离开待清洁面时，后一刮条122已经接触待清洁面，以避免待清洁面出现未清洁区域。而将第一偏转角设置成90度，前一刮条122靠近第一轴端的部分未开待清洁面，后一刮条122靠近第二轴端已经接触待清洁面，两个刮条122形成两点支撑结构，可减小刮条122触地时产生的冲击，提高滚刷使用的平稳性。
在其他实施例中，根据实际应用情况，贯通孔112和刮条122的数量也可以设置为其他数量，并且优选设置为超过本实施例中的数量。另外，在其他实施例中，第一偏转角的角度也可以大于相邻两个贯通孔112之间扇形柱面对应的圆心角。
另外，在其他实施例中，贯通孔112的延伸方向也可以设置成平行于滚刷的母线，对应的，刮条122的延伸方向设置成平行于芯轴本体121的母线。
如图4和图5所示，本实施例中，贯通孔112的侧壁与刷辊11的径向方向形成第一夹角，并且第一夹角为锐角。参照图4和图5所示的滚刷转动方向，贯通孔112的侧壁可以使得刮条122自由端的延伸方向与刷辊11的径向方向之间的夹角为锐角，并且刮条122 的延伸方向与滚刷的外周面的旋转切线方向的夹角也为锐角。如此，刮条122可以起到更好地刮扫待清洁面的作用，提高清洁效果。
应当注意，为达成前段提及的效果，滚刷应当按照图1、图4和图5的方向旋转，如果按照相反的方向旋转，相应的清洁效果也就减弱。
请继续参见图4和图5，本实施例中，在刷辊11的内侧周面上设置有第一限位凸块13，在芯轴本体121的外周侧面设置有第二限位凸块14。第一限位凸块13和第二限位凸块14的高度和大于刷辊11的内侧周面到芯轴本体121的距离。
当芯轴本体121相对刷辊11转动至如图5所示的位置时，第一限位凸块13贴靠第二限位凸块14而限制芯轴本体121相对于刷辊11在第一方向的继续转动(第一方向为图示方向的相反方向)，继而避免刮条122脱离贯通孔，完全回缩到刷辊11的内腔111中。
如图5所示，在本实施例中，贯通孔112位于刷辊11外周侧面的一侧设置有沉孔部114。当第一限位凸块13触碰第二限位凸块14时，刮条122的自由端回缩至沉孔部114内，避免刮条122被意外剐蹭。另外，设置沉孔部114也有利于使用外力拉拽刮条122而将其从贯通孔112中拉出。
当然，在其他实施例中也可以不设置前述的沉孔部114；此外，当第一限位凸块13触碰第二限位凸块14时，刮条122的自由端也可以伸出刷辊11的外侧周面。
仍请继续参见图4和图5，在刷辊11的内周侧面设置有第三限位凸块15，在芯轴本体121的外侧周侧面设置有第四限位凸块16；第三限位凸块15的高度和第四限位凸块16的高度和大于刷辊11的周侧面到芯轴本体121外周侧面的距离。第三限位凸块15和第四限位凸块16配合，限制芯轴本体111相对于刷辊11在第二方向的继续转动(即限制沿图示方向的继续转动)。参见图4可知，当第三限位凸块15触碰第四限位凸块16时，刮条122伸出刷辊11的长度最长，刮条122与芯轴本体121连接处到贯通孔112的距离最短；如果继续沿图示方向旋转，刮条122与芯轴本体121的距离增大，反而使刮条122反向运动、伸出刷辊11的长度变短。
请参见图1和图2，本实施例中，在刷辊11的第一端设置有第一端盖17。第一端盖17的轴心处设置有第一通孔171。第一端盖17与刷辊11固定连接，并且可以拆卸。芯轴本体121穿过第一通孔171，并相对第一通孔171可转动。
第一端盖17可以起到支撑刷辊11，避免刷辊11设置开口113的一端形变；另外，第一端盖17还起到支撑芯轴本体121的作用，避免滚刷转动时芯轴本体121在内腔111中摆动。。
本实施例中，芯轴本体121包括轴芯部和中心轴123。轴芯部的轴心处设置有轴心孔125。中心轴123插入到轴心孔125内，与轴芯部固定连接。具体应用中，中心轴123和轴芯部可以采用过盈连接或者键连接。前文所述的芯轴本体121穿过第一通孔171实际是中心轴123穿过第一通孔171，而轴芯部完全设置在内腔111中。
当然，在其他实施例中，轴芯部和中心轴123也可以一体地设置。例如，可以采用注塑工艺，直接将轴芯部熔塑到中心轴123上。另外，在其他实施例中，也可以不设置中心轴123，而是利用吸尘器中的轴件穿过第一通孔171与轴芯部连接(当然，从功能角度考虑，吸尘器中的轴件与中心轴123的功能相同，吸尘器的轴件也可以认为是滚刷的一部分)。
在此也做提醒，为便于加工，本实施例中刮条122和轴芯部为一体设置；在其他实施例中，二者也可以分体设置。
本实施例中，中心轴123可以相对于第一端盖17中的第一通孔171转动；在其他实施例中，中心轴123还可以与第一通孔171固定连接，实现芯轴本体121相对于刷辊11的固定；也就是，在其他实施例中，第一端盖17即为前文中提及的连接固定件。
具体应用中，中心轴123与第一通孔171可以为过盈配合或者键连接，优选采用键连接。当然，如果需要调整刮条122伸出刷辊11的长度，应当先卸下第一端盖17，解除第一端盖17与刷辊11和中心轴123的固定连接。
请参见图2，本实施例提供的滚刷中，在中心轴123伸出第一通孔171的轴端设置有凹槽124；此凹槽124功能类似于螺钉钉头的凹槽，用于驱动芯轴件12转动。在其他实施例中，凹槽124也可以设置在中心轴123的其他位置，例如设置在中心轴123伸出第一通孔171的轴端周面上。另外，在其他实施例中，也可以设置其他实现凹槽124功能的结构。
请参见图1、图3和图9，本实施例提供的滚刷还包括第二端盖18。第二端盖18设置在刷辊11的第二轴端，并与刷辊11固定连接；实际应用中，第二端盖18和刷辊11优选采用键连接。
在第二端盖18的轴心处设置有第二通孔181；驱动滚刷转动的驱动电机的输出轴19插入到第二通孔181中，以键连接方式与第二端盖18固定连接。如此，驱动电机的输出轴19带动第二端盖18转动，第二端盖18带动刷辊11转动，而刷辊11推动刮条122转动，刮条122又带动芯轴本体121转动，实现了刷辊11的整体转动。
本实施例中，驱动电机的输出轴19的自由端插入到刷辊11的内腔111中，并插入到轴心孔125中，与轴心孔125滑动接触。这一结构可以更好地支撑芯轴本体121，并且不会影响外力作用下芯轴本体121相对于刷辊11的转动。
当然，在其他实施例中，驱动电机的输出轴19还可以以键连接的方式与轴心孔125连接；在此情况下，第二端盖18也起到了连接固定件的作用。
本实施例中，为了便于各个部件的加工，第二端盖18被设置为一个独立于刷辊11的部件。在其他实施例中，第二端盖18也可以与刷辊11一体地设置。
此处，提请注意，本实施例中的刷辊11外周侧面可以设置为光滑面，也可以设置成具有刷毛或者刮条的表面，只是其表面的刷毛或者刮条不能过长。另外，提请注意的时，附图中两个剖面图中的剖面线仅是用来显示相应的组件，并不对相应组件的材料特性做限定。
除了提供前述的滚刷外，本申请实施例还提供一种采用前述滚刷的吸尘器。吸尘器包括设置在工作端的驱动电机、吸尘口和前述滚刷；驱动电机的输出轴19与滚刷连接而带动滚刷整体转动，吸尘口设置在滚刷的后侧，利用负压抽吸滚刷转动扫起的污渍。
当然，本实施例提供的滚刷并不仅限于使用在吸尘器中，也可以使用在一些可能使用此类滚刷的搅拌设备、涂布设备中。
以上描述仅为本申请的较佳实施例以及对所运用技术原理的说明。本领域技术人员应当理解，本申请中所涉及的发明范围，并不限于上述技术特征的特定组合而成的技术方案，同时也应涵盖在不脱离上述发明构思的情况下，由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与本申请中公开的(但不限于)具有类似功能的技术特征进行互相替换而形成的技术方案。
