驱动机构2包括动力源29和传动组件21，传动组件21包括第一驱动轮22、第二驱动轮26、第一驱动件23和第二驱动件24，第一驱动轮22和第二驱动轮26均与动力源29相连，其中，动力源29可设置为驱动电机，第一驱动轮22和第二驱动轮26均可设置为皮带轮，且可在驱动电机的电机轴上设置主动轮291，第一驱动轮22的转动轴线和第二驱动轮26的转动轴线均与主动轮291的转动轴线平行，且第一驱动轮22和第二驱动轮26分别与主动轮291在径向上正对设置，这样，主动轮291和第一驱动轮22、第二驱动轮26均通过皮带传动配合，以使驱动电机输出的驱动力能够在主动轮291处通过皮带传递至第一驱动轮22和第二驱动轮26，进而通过第一驱动轮22和第二驱动轮26朝向第一驱动件23和第二驱动件24进行分配。
第一驱动轮22处的动力通过第一驱动件23驱动滚刷体11转动，第二驱动轮26处的动力通过第二驱动件24驱动套筒12转动，即第一驱动轮22与第一驱动件23相连以用于驱动滚刷体11转动，第二驱动轮26与第二驱动件24相连以用于驱动套筒12转动，其中，如图5所示，第一驱动件23可构造为圆形块，以使第一驱动件23具有自身的转动轴线，且可绕自身转动轴线转动，第二驱动件24也可构造为圆形块，以使第二驱动件24具有自身的转动轴线，且也可绕自身转动轴线转动。且如图3所示，第一驱动件23与滚刷体11的右端直接接触配合，第一驱动件23能够带动滚刷体11转动，且第二驱动件24与套筒12的右端直接接触配合，第二驱动件24能够带动套筒12转动。也就是说，在第一驱动轮22处可将来自驱动电机的一部分驱动力输出给第一驱动件23以使滚刷体11在套筒12内转动，且自驱动电机的另一部分驱动力可通过第二驱动轮26输出给第二驱动件24以使套筒12相对于壳体1001转动。
第一驱动件23与第二驱动件24偏心设置以使刷毛112从套筒12内选择性地伸出或缩回，也就是说，通过第一驱动件23驱动滚刷体11转动时以及第二驱动件24驱动套筒12转动时，滚刷体11的轴线与套筒12的轴线间隔开。需要说明的是，如图3所示，滚刷体11的转动轴线低于套筒12的转动轴线，且在滚刷体11的外周壁上的多个不同位置处均设置有刷毛112，同时在套筒12的外周壁上设有多个不同的避让开孔122，以在滚刷体11的外周壁上的刷毛112和套筒12的避让开孔122均位于下部区域时，该处的刷毛112从避让开孔122处朝下伸出以用于对待清洁面进行清洁作用，而在滚刷体11的外周壁上的刷毛112和套筒12的避让开孔122均位于上部区域时，该处的刷毛112从避让开孔122处收缩至套筒12内。
由此，可多设置刷毛112和避让开孔122的配合数量，以使地刷总成100的底部始终有刷毛112从避让开孔122处伸出，从而持续地对地面进行清洁，保证吸尘器1000的清洁度。
可以理解的是，在刷毛112从套筒12中伸出时，能够对地面进行清洁，且在刷毛112从套筒12中缩回时，刷毛112处的杂物能够在避让开孔122的孔壁的作用下与刷毛112脱离，从而避免刷毛112处缠绕的杂物过多影响滚刷体11的正常转动，由此，可利于降低刷毛112的清理难度，不需用户手动清洁，提高实用性，从而解决毛发、细线等细长物缠绕滚刷体11的问题。
其中，在第二驱动轮26的径向内壁上设有第一卡接部262，在第二驱动件24朝向靠近第二驱动轮26的一端设有第二卡接部244，以在将第二驱动轮26与第二驱动件24相连时，第二驱动件24上的第二卡接部244能够与第二驱动轮26的第一卡接部262卡接配合，从而实现通过第一卡接部262与第二卡接部244卡接配合以使第二驱动轮26与第二驱动件24沿周向相对固定，便于增强第二驱动轮26与第二驱动件24的连接稳定性，且不占用额外的安装空间，便于减小驱动结构的整体结构尺寸。
由此，本申请中的两个皮带轮分别与两个驱动件传动配合，也就是说，本申请中的两个驱动轮和两个驱动件之间的传动结构未采用传统的齿轮传动的结构设计，如此设置，不仅能够降低两个皮带轮和两个驱动件之间的装配精度要求，降低装配难度，不会存在齿轮传动所存在的磨损过大的问题，利于延长驱动机构2的使用寿命，极大地提高了地刷总成100的可靠性和安全性。且第二驱动轮26与第二驱动件24之间采用卡接配合的方式，能够解决定制齿轮齿廓间滑动摩擦导致的噪音大、易磨损无法克服的问题，且结构尺寸更小，使得地刷总成100的结构更加紧凑。
根据本申请实施例的用于吸尘器的地刷总成100，通过将第一驱动件23和第二驱动件24偏心设置以使刷毛112从套筒12内选择性地伸出或缩回，能够有效地解决毛发、细线等 细长物缠绕滚刷体11的问题，且两个驱动轮和两个驱动件传动配合，能够提高传动效率，同时，第二驱动轮26和第二驱动件24卡接配合，利于减小地刷总成100的整体结构尺寸，能够避免产生噪音，且传动过程中部件磨损小，不会存在产生振动的问题，从而提高地刷总成100的整体性能。
在一些实施中，驱动机构2还包括驱动壳28和传动轴25，传动轴25可转动地安装于驱动壳28内，第一驱动轮22安装于传动轴25且与传动轴25沿周向相对固定，即在驱动壳28内部形成安装空间，以将传动轴25安装于驱动壳28内，从而通过驱动壳28对传动轴25以及驱动壳28内部的其他结构起到保护的作用，其中，第一驱动轮22与传动轴25相连，第一驱动轮22在传动轴25的周向上与传动轴25相对固定，利于增强第一驱动轮22与传动轴25的连接稳定性，防止第一驱动轮22与传动轴25之间产生转动，从而便于传动轴25带动第一驱动轮22驱动滚刷体11转动。
第二驱动件24可转动地支撑于驱动壳28，便于通过驱动壳28对第二驱动件24起到支撑的作用，且第二驱动轮26可转动地套设于传动轴25外，以使第二驱动轮26和第一驱动轮22共同安装于传动轴25实现同轴布置，利于提高传动组件21的集成度，从而利于第二驱动轮26能够更好地带动第二驱动件24驱动套筒12转动。
其中，传动轴25贯穿第二驱动件24且伸至驱动壳28外以与第一驱动件23沿周向固定相连。也就是说，传动轴25伸出驱动壳28的一端贯穿第二驱动件24与第一驱动件23相连，且二者之间在传动轴25的周向上相对固定，可以理解的是，第一皮带221轮、传动轴25、第一驱动件23与滚刷体11动力连接，同时第二皮带261轮、第二驱动件24和套筒12动力连接，以便于第一驱动件23和第二驱动件24分别使滚刷体11和套筒12转动，由此，可实现地刷总成100在运行的过程中，刷毛112能够从套筒12中有效地伸出和缩回，实现对地面的清洁和对刷毛112上细长物的脱去，提高结构设计的合理性，提升地刷总成100的实用性。
在一些实施例中，第二驱动件24包括支撑连接部242和传动部241，其中，传动部241的径向尺寸大于支撑连接部242的径向尺寸，且传动部241的中部朝向滚刷体11敞开且形成中部安装空间，以便于传动轴25依次贯穿支撑连接部242和传动部241，且支撑连接部242可转动地支撑于驱动壳28，传动部241与支撑连接部242的第一端(如图5所示的左端)相连且传动部241位于驱动壳28外以与套筒12相连，支撑连接部242的第二端伸至驱动壳28内且设有第二卡接部244。也就是说，在第二驱动件24与套筒12配合安装时，传动部241在驱动壳28外且与套筒12相连，设于支撑连接部242的第二端(如图5所示的右端)的第二卡接部244伸至驱动壳28内以与设于第二驱动轮26上的第一卡接部262卡接配合，且支撑连接部242的外周壁与驱动壳28的内周壁转动配合，从而便于第二驱动 轮26驱动第二驱动件24以带动套筒12转动，且便于驱动壳28对支撑连接部242起到支撑的作用，增强第二驱动件24的稳定性。
在一些实施例中，如图6所示，第二卡接部244包括卡接悬臂244a和卡扣244b，卡接悬臂244a和卡扣244b可构造为一体结构，便于降低生产难度，卡接悬臂244a设于支撑连接部242的第二端，如图6所示，卡接悬臂244a设于支撑连接部242的右端，且朝远离支撑连接部242的方向延伸，即卡接悬臂244a朝向靠近第二驱动轮26的方向沿轴向延伸，卡扣244b设于卡接悬臂244a的自由端且沿径向向外凸起。需要说明的是，第二卡接部244的径向内部形成有安装空间，便于传动轴25贯穿第二卡接部244，且便于第二卡接部244在受到径向向内的压力时，能够朝向安装空间弹性变形。
如图7所示，第一卡接部262包括卡接凸台，卡接凸台设于第二驱动轮26的内周壁，且卡接凸台沿径向向内凸起，不会占用额外的安装空间，便于减小驱动结构的整体结构尺寸。这样，在第二驱动件24与第二驱动轮26卡接配合时，传动轴25穿过第二驱动件24和第二驱动轮26，且设于第二驱动件24的第二卡接部244伸至第二驱动轮26内，此时，设于第二卡接部244自由端的卡扣244b与第二驱动轮26的内周壁相抵，从而使得卡接悬臂244a沿径向向内弹性变形，当卡扣244b通过后，卡接悬臂244a回复初始位置，从而设于卡接悬臂244a自由端的卡扣244b与卡接凸台实现卡接配合，从而利于减小地刷总成100的整体结构尺寸，能够避免发生磨损和产生噪音，且传动过程中部件磨损小，不会存在产生振动的问题，从而提高地刷总成100的整体性能。
如图6所示，卡接悬臂244a可为多个，也就是说，卡接悬臂244a的数量可根据实际的安装需求进行灵活设计，且多个卡接悬臂244a沿支撑连接部242的周向间隔开设置，以便于周向间隔开设置的多个卡接悬臂244a之间不会互相产生影响，即在某个卡接悬臂244a出现故障时，其他的卡接悬臂244a仍能与卡接凸台实现配合。
如图7所示，卡接凸台也可为多个，也就是说，卡接凸台的数量可根据实际的安装需求进行灵活设计，且多个卡接悬臂244a与多个卡接凸台一一对应，即卡接悬臂244a的数量与卡接凸台的数量相同，以便于每个卡接凸台均可与一个对应的卡接凸台实现卡接配合，从而增强第二驱动件24与第二驱动轮26的卡接稳定性，以在传动过程中，避免发生磨损和产生噪音，降低部件磨损，且不会存在产生振动的问题，从而提高地刷总成100的整体性能。
在一些实施例中，如图6所示，在支撑连接部242的周向上，任意相邻两个卡接悬臂244a之间均设有弱化槽5，也就是说，每两个相邻的卡接悬臂244a之间均设有一个弱化槽5，以便于将多个卡接悬臂244a间隔开，保证相邻的两个卡接悬臂244a之间不会互相影响。也就是说，通过弱化槽5的设置，以使在支撑连接部242的周向上各个卡接悬臂244a之间 无连接关系，利于弱化卡机悬臂的结构强度，利于实现卡接悬臂244a在径向上的弯曲变形，即卡接悬臂244a在受到第二驱动轮26的内周壁的挤压作用下，能够沿径向向内朝安装空间内变形，以使卡接悬臂244a能够顺利地伸至第二驱动轮26背离传动部241的一侧，从而利于实现支撑连接部242与第二驱动轮26的快速卡接，提高装配效率。
在一些实施例中，如图3所示，用于吸尘器的地刷总成100还包括：轴承支撑块27。需要说明的是，在第二驱动件24内安装有轴承3，且轴承支撑块27通过轴承3可转动支撑于第二驱动件24内，以使轴承支撑块27在第二驱动件24内可转动。
其中，轴承支撑块27设有偏心孔271，传动轴25的第一端可转动地支撑于偏心孔271，且传动轴25伸出偏心孔271的部分与第一驱动件23相连。需要说明的是，偏心孔271的轴线与第二驱动件24的轴线错开设置，其中，轴承支撑块27可为圆形块，且偏心孔271设置于轴承支撑块27的下部区域处，即偏心孔271的轴线低于轴承支撑块27的轴线，以使传动轴25通过轴承3可转动地支撑于轴承支撑块27的下部位置处。
可以理解的是，轴承支撑块27安装于第二驱动件24内的下部位置，且轴承支撑块27同时与第二驱动件24和传动轴25通过轴承3转动配合，这样，在实际运行的过程中，第二驱动轮26可驱动第二驱动件24相对于轴承支撑块27转动，以带动套筒12转动，同时第一驱动轮22可通过传动轴25驱动第一驱动件23相对于轴承支撑块27转动，以带动滚刷体11转动，从而实现滚刷体11相对于套筒12的偏心转动。
也就是说，本申请中，通过轴承支撑块27的设计，使得第一驱动件23和第二驱动件24能够合理地偏心安装，同时能够实现第一驱动件23和第二驱动件24的合理地偏心转动，从而利于实现两个驱动轮以两条不同的路径分别对滚刷体11和套筒12进行转动驱动，由此，可实现地刷总成100在运行的过程中，刷毛112能够从套筒12中有效地伸出和缩回，实现对地面的清洁和对刷毛112上细长物的脱去，提高结构设计的合理性，提升地刷总成100的实用性。
在一些实施例中，驱动壳28包括电机支架281和驱动侧端盖282，电机支架281与动力源29相连，且驱动侧端盖282可拆卸安装于电机支架281，如图4所示，在电机支架281的外周壁和驱动侧端盖282的外周壁均设有三个连接柱，连接柱设有沿传动轴25的轴向贯通的连接孔，这样，在电机支架281的周向上可通过三个螺栓贯穿连接柱的连接孔，以实现电机支架281和驱动侧端盖282的连接固定，且二者能够灵活地拆卸安装，结构简单，拆装方便，便于后期对内部的零部件进行拆卸和更换。
如图所示，电机支架281和驱动侧端盖282安装配合且形成传动组件21的驱动壳28，电机支架281与驱动电机的外壳固定相连，以使传动组件21和动力源29连接为一体结构。电机支架281和驱动侧端盖282相连且限定出安装空间，第一驱动轮22和第二驱动轮26均 安装于该安装空间内，以使电机支架281和驱动侧端盖282对第一驱动轮22和第二驱动轮26与其他部件之间的配合结构起到保护的作用。
且如图5所示，电机支架281设有朝向驱动电机的主动轮291敞开的导向腔，需要说明的是，如图5所示，在主动轮291处还可设有间隔组件291a，间隔组件291a在主动轮291的轴向上设于主动轮291的中间位置，以将主动轮291分为左部分和右部分，使得第一皮带221和第二皮带261在套设于主动轮291上时，防止两个皮带之间产生干涉，便于第一皮带221和第二皮带261分别带动第一驱动轮22和第二驱动轮26转动。
具体地，与第二驱动轮26配合的第二皮带261的一端套设于第二驱动轮26外，且第二皮带261的另一端通过导向腔伸至主动轮291的左部分处以套设于主动轮291外，从而使得第二皮带261能够在第二驱动轮26和主动轮291之间起到传动的作用。
进一步地，与第一驱动轮22配合的第一皮带221的一端套设于第一驱动轮22外，且第一皮带221的另一端通过导向腔伸至主动轮291的右部分处以套设于主动轮291外，从而使得第一皮带221能够在第一驱动轮22和主动轮291之间起到传动的作用。
由此，通过第一驱动轮22、第二驱动轮26分别与第一皮带221、第二皮带261的传动配合，能够避免齿轮传动所存在的磨损过大的问题，且能够降低传动时产生的噪音，利于延长驱动机构2的使用寿命，极大地提高了地刷总成100的可靠性和安全性。
其中，传动轴25远离滚刷体11的一端可转动地支撑于驱动侧端盖282，第二驱动件24可转动地支撑于电机支架281。如图所示，传动轴25的右端通过轴承3可转动地支撑于驱动侧端盖282上，以使传动轴25能够相对于电机支架281和驱动侧端盖282转动，且在电机支架281的侧壁上设有安装通孔，第二驱动件24通过轴承3可转动地支撑于电机支架281的侧壁上，在第二驱动件24的支撑连接部242外套设有轴承3，即该轴承3的内圈与支撑连接部242的外周壁固定相连，且该轴承3的外周壁固定支撑于安装通孔的内周壁。
由此，可实现传动组件21内部的结构安装，结构简单，安装方便。其中，在第一驱动轮22和第二驱动轮26的外周壁均可设有外凸齿，且可在皮带的内周壁设有内凸齿，以使内凸齿和外凸齿啮合传动，从而利于增强皮带与两个驱动轮之间的配合作用，避免两个驱动轮在传动的过程中与皮带出现打滑的问题，提高皮带传动的可靠性。
在一些实施例中，如图5所示，第一驱动件23朝向滚刷体11的一侧设有第一驱动齿231，滚刷体11朝向第一驱动件23的一侧设有第一从动齿，第一驱动齿231与第一从动齿啮合，第一驱动齿231形成于第一驱动件23的外周壁且在第一驱动件23的外周壁沿径向向外凸出，第一驱动齿231延伸至第一驱动件23朝向滚刷体11的侧面，且如图5所示，第一从动齿形成于滚刷体11的右端的内周壁，且第一从动齿在滚刷体11的内周壁沿径向向内凸出，第一从动齿延伸至滚刷体11朝向第一驱动件23的侧面，这样，可将第一从动齿和第 一驱动齿231在轴向上插接配合，且第一从动齿和第一驱动齿231在周向上限位配合，以使第一驱动件23能够通过第一驱动齿231带动第一从动齿和滚刷体11转动。
如图5所示，第二驱动件24朝向套筒12的一侧设有第二驱动齿243，套筒12朝向第二驱动件24的一侧设有第二从动齿，第二驱动齿243与第二从动齿啮合，如图5和图6所示，第二驱动齿243形成于第二驱动件24的外周壁且在第二驱动件24的外周壁沿径向向外凸出，第二驱动齿243延伸至第二驱动件24朝向套筒12的侧面，第二从动齿形成于套筒12的右端的内周壁，且第二从动齿在套筒12的内周壁沿径向向内凸出，第二从动齿延伸至套筒12朝向第二驱动件24的侧面，这样，可将第二从动齿和第二驱动齿243沿轴向上插接配合，且第二从动齿和第二驱动齿243在周向上限位配合，以使第二驱动件24能够通过第二驱动齿243带动第二从动齿和套筒12转动。
由此，通过在第一驱动件23和滚刷体11、第二驱动件24和套筒12之间通过齿结构啮合传动，以使动力源29通过传动组件21能够很好地驱动滚刷体11和套筒12转动，从而实现对地面的清洁作用。
