Description

清洁设备 技术领域
本发明涉及一种清洁设备，属于小家电制造技术领域。
背景技术
扫地机器人以其灵活耐用受到消费者的广泛使用，滚刷是扫地机器人的核心清洁装置，其结构的合理程度直接影响到扫地机器人的作业效果。目前市场上以滚刷作为清洁装置的产品大部分采用的是单滚刷，比如：公开号为CN 1895152A和CN103330537A的专利文献。有的为了增强清洁效果，采用两根旋转方向相反的滚刷同时清扫，比如：授权公告号为CN 201036542Y的专利文献、公开号为CN 101305896A的专利文献、以及US4850077。在现有技术中，无论是采用的单滚刷还是双滚刷，其滚刷安装方式都是通过两端固定的通轴实现驱动的，即使将驱动装置设置在中部，表面上看来驱动装置将通轴分成两段，但实质上仍然是采用一根驱动轴进行驱动的。由于滚刷在工作状态下都是回转体，只有其质心在中心轴上，滚刷在转动的时候才不会产生震动。但在实际制作过程中，其质心并不能保证一定在中心轴上，即滚刷转动时会产生震动。长形滚刷及其内部的驱动轴，在由震动所造成的甩动过程中，其本身的刚度不足以克服甩动带来的离心力，在使用一段时间后，滚刷会变形，进而无法正常工作。
发明内容

为了提高工作效率，所述滚刷装置还包括设置在第二轴线上的两个以上的第二滚刷单元，第二轴线与所述第一轴线平行，相邻两个第二滚刷单元之间设有支撑单元。
为了减少在作业过程中产生的清扫盲区，两个以上所述第一滚刷单元的邻接点在所述第一轴线上的设置位置，与两个以上所述第二滚刷单元的邻接点在所述第二轴线上的设置位置彼此错开。
为了节约能源同时使滚刷装置的结构紧凑，所述驱动单元中对应设置在第一轴线上的第一传动部件，其设置位置位于相邻两个第一滚刷单元之间；所述驱动单元中对应设置在第二轴线上的第二传动部件，其设置位置位于相邻两个第二滚刷单元之间。
更具体地，所述驱动单元主要包括壳体，所述壳体包括箱座和分别设置在箱座左、右两侧的箱盖；所述箱座上固定有驱动电机，所述驱动电机通过传动机构传递动力并分别驱动第一滚刷单元和第二滚刷单元转动；所述驱动单元的壳体与支架组件固定连接。
进一步地，所述传动机构包括：与所述驱动电机的输出端相连的一级齿轮，一级齿轮与二级齿轮啮合，再通过第一同步带连接所述第一传动部件，所述第一传动部件包括第一滚刷支撑轮组件，所述第一滚刷支撑轮组件的左、右两端分别与第一滚刷单元固定；
所述一级齿轮通过第二同步带与第一同步带惰轮连接，该第一同步带惰轮又通过第三同步带与所述第二传动部件连接，所述第二传动部件包括第二滚刷支撑轮组件，所述第二滚刷支撑轮组件的左、右两端分别与第二滚刷单元固定。
所述支撑单元为设置在所述壳体前、后两个位置上的第一支撑孔和第二支撑孔，所述第一支撑孔和第二支撑孔分别与第一滚刷单元和第二滚刷单元同轴；所述第一滚刷支撑轮组件、第二滚刷支撑轮组件分别通过轴承与第一支撑孔和第二支撑孔连接。
所述第一滚刷支撑轮组件具体包括支撑轮和设置在其内部的滚刷输出齿轮轴，滚刷输出齿轮轴的两端直接和第一滚刷单元相连，滚刷输出齿轮轴两端分别通过轴承固 定在所述驱动单元的壳体上；所述第一滚刷支撑轮组件的结构与第二滚刷支撑轮组件的结构相同。
综上所述，本发明有效防止滚刷体太长导致其工作过程中震动大并出现滚刷体变形的可能，将单轴滚刷截成多个滚刷单元，对于双轴滚刷，则将两轴上的滚刷分别截成长短不同的两个滚刷单元，并使两轴上滚刷单元的设置位置彼此错开，使一轴上的滚刷单元清扫盲区被另一轴上的滚刷单元清扫区域覆盖，有效减少清扫盲区，结构简单且清洁效率高。

具体实施方式
实施例一
图1为实施例一滚刷装置的外部结构示意图；图2为实施例一滚刷装置的爆炸图。如图1并结合图2所示，本实施例针对现有技术中的不足，提供一种清洁设备(图中未示出)，该清洁设备上设有滚刷装置1000，本发明主要是将现有较长的传动轴和滚刷截成多个长度较短的第一滚刷单元120，第一滚刷单元的数量可以为两个或两个以上，进而提高其本身的抗变形能力。具体来说，所述滚刷装置1000包括第一滚刷单元120，所述第一滚刷单元120的设置数量为两个以上，在图1、图2所示的实施例中，滚刷单元120的设置数量为两个，且该两个第一滚刷单元120均位于同一轴线上，该轴线为第一轴线。两个所述第一滚刷单元120均由同一驱动单元140驱动，相邻两个 第一滚刷单元120之间还设有支撑单元。如图2所示，所述支撑单元为开设在滚刷支架110端面上的支撑孔111，所述支撑孔111与第一滚刷单元120同轴。滚刷同步带轮144的两侧分别通过轴承146与所述支撑孔111连接。更具体地，如图2所示，所述滚刷装置还包括滚刷支架110和滚刷盖板130，所述第一滚刷单元120设置在滚刷支架110和滚刷盖板130围设的空间内。
如图1、图2所示的实施例中，驱动单元140是设置在相邻的两个第一滚刷单元120之间的。当然，除了可以将驱动单元140设置在整个滚刷装置的中部，其设置位置也可以在某一第一滚刷单元的一侧端部，在这样的驱动方式下，多个第一滚刷单元可以通过一个简单的接头固定连接，该接头同样可以通过轴承连接在滚刷支架110上。也就是说，根据实际需要，所述驱动单元140的设置位置既可以在相邻两个第一滚刷单元120之间，又可以设置在滚刷装置最外侧的那个第一滚刷单元的侧端部。
如图2所示，驱动机构140的具体结构包括：设置在中间的电机固定支架142，其上固定有驱动电机141，分别固设在左、右两侧的第一滚刷单元120通过电机同步带轮143、同步带145和滚刷同步带轮144实现同步转动。驱动电机141通过同步带145，借助滚刷同步带轮144带动第一滚刷单元120转动。滚刷同步带轮144两侧分别设有轴承146，轴承内圈与滚刷同步带轮144固定，轴承外圈与滚刷支架110端面上的支撑孔111固定，从而使滚刷支架110对设置在其两侧的第一滚刷单元120均能够起到支撑的作用，避免因单根滚刷太长而发生变形。
除了采用上述结构之外，还可以将电机固定支架142固定在滚刷支架110上，此时，轴承外圈则固定在电机固定支架142上。同样地，也可以在电机固定支架142的端面上开设支撑孔(图中未示出)，该支撑孔同样与第一滚刷单元同轴，滚刷同步带轮144的两侧可以分别通过轴承与该支撑孔连接。也就是说，电机固定支架142可以单独设置或者固定在滚刷支架110上。
图3为第一滚刷单元结构爆炸图。如图2并结合图3所示，第一滚刷单元120主要包括滚刷本体121和设置在滚刷本体两端的端盖122，转轴123穿过端盖122，借助转动轴承124使滚刷本体121可旋转固定在转轴123上，为了减少转动中产生的震动，转动轴承124的外侧还设有减震圈125。图3中所示的设置在左侧的端盖122，该端盖122的端部上设有凸起，可以直接插入滚刷同步带轮144端部的凹槽内实现两者的连接。
基于上述结构，本实施例的动作过程是这样的：驱动电机141工作，驱动电机同步带轮143旋转，进而通过同步带145带动滚刷同步带轮144，并分别驱动两侧的第 一滚刷单元120同向、同速转动。
实施例二
图4为实施例二滚刷装置的外部结构示意图；图5为实施例二滚刷装置的整体结构示意图。如图4并结合图5所示，为了提高工作效率，在本实施例中所提供的滚刷装置2000，除了设置在第一轴线上的两个第一滚刷单元120之外，还包括设置在第二轴线上的两个以上的第二滚刷单元220。第二轴线与第一轴线相互平行。为了保证滚刷单元的稳定性，在相邻两个第二滚刷单元220之间设有支撑单元，该支撑单元的具体结构在下文中做详细说明。为了减少在作业过程中产生的清扫盲区，两个第一滚刷单元120的邻接点在所述第一轴线上的设置位置，与两个第二滚刷单元220的邻接点在所述第二轴线上的设置位置彼此错开。为了节约能源同时使滚刷装置的结构紧凑，所述驱动单元240中对应设置在第一轴线上的第一传动部件，其设置位置位于相邻两个第一滚刷单元120之间；所述驱动单元240中对应设置在第二轴线上的第二传动部件，其设置位置位于相邻两个第二滚刷单元220之间。
图6为实施例二滚刷装置的爆炸图。对照图1、图2所示的实施例一中的单轴滚刷装置的结构，在本实施例中，提供了一种双轴滚刷装置，具体来说，如图6所示，本实施例中的滚刷装置可以包括支架组件201、第一滚刷单元120和第二滚刷单元202，以及滚刷盖板203。其中，支架组件201还包括滚刷风道盖板2011、滚刷驱动支架2012和吸尘管道支架2013，在吸尘管道支架2013上还设有吸尘管道2014。当然，滚刷装置内部的具体结构，本领域技术人员还可以根据实际的需要进行其他适应性修改，这里不再一一赘述。
图7为实施例二驱动单元的剖视图；图8和图9分别为实施例二驱动单元的外部结构示意图；图10为实施例二驱动单元的爆炸图。如图7至图10所示，具体来说，所述驱动单元240主要包括壳体，该壳体包括箱座241和分别设置在箱座左、右两侧的箱盖242。所述箱座241上固定有驱动电机243，所述驱动电机通过传动机构传递动力并分别驱动第一滚刷单元120和第二滚刷单元220转动。所述驱动单元的壳体与支架组件201固定连接。具体来说，所述传动机构包括：与所述驱动电机243的输出端2431相连的一级齿轮244，一级齿轮244与二级齿轮245啮合，再通过第一同步带246连接所述第一传动部件，所述第一传动部件包括第一滚刷支撑轮组件247(即：图10中的A部分)，所述第一滚刷支撑轮组件247的左、右两端分别与第一滚刷单元120固定。所述一级齿轮244通过第二同步带248与第一同步带惰轮249连接，该第一同 步带惰轮249又通过第三同步带250与所述第二传动部件连接，所述第二传动部件包括第二滚刷支撑轮组件251，所述第二滚刷支撑轮组件251的左、右两端分别与第二滚刷单元220固定。通过上述的结构设置，实现了第一轴线和第二轴线的输出转速相同，旋转方向相反，这样，分别设置在第一轴线上的两个第一滚刷单元120和设置在第二轴线上的两个第二滚刷单元220的输出转速相同，旋转方向相同，从而进一步达到更好的清洁效果。
结合图10所示，在所述壳体前、后两个位置上设有第一支撑孔2411和第二支撑孔2412形成支撑单元。所述第一支撑孔2411和第二支撑孔2412分别与第一滚刷单元120和第二滚刷单元220同轴。所述第一滚刷支撑轮组件247、第二滚刷支撑轮组件251分别通过轴承与第一支撑孔2411和第二支撑孔2412连接。
图11为图10的A局部结构示意图。如图11所示，为第一滚刷支撑轮组件247的结构示意图，第一滚刷支撑轮组件247和第二滚刷支撑轮组件251的结构相同。所述第一滚刷支撑轮组件247具体包括支撑轮2471和设置在其内部的滚刷输出齿轮轴2472，滚刷输出齿轮轴2472的两端直接和第一滚刷单元120相连，滚刷输出齿轮轴2472两端分别通过轴承固定在所述驱动单元的壳体上。
如前所述并结合图4所示可知，为了避免遗漏清洁点，减少清洁盲区，分别设置在不同轴线上的第一滚刷单元120和第二滚刷单元220呈错位排布，对于滚刷装置整体来说，相当于长度不同的四根滚刷交错排布。驱动单元240设置在滚刷装置2000整体基本上处于中部的位置，在输出动力的同时也可以对两端的第一滚刷单元和第二滚刷单元分别起到支撑的作用。具体来说，结合图11所示，滚刷支撑轮组件247中连接两段滚刷的滚刷齿轮输出轴2472的两侧分别设有轴承，其中轴承内圈与滚刷齿轮输出轴2472固定，轴承外圈与驱动单元240的箱座241固定，使箱座241对分别设置在不同轴线上的第一滚刷单元和第二滚刷单元起到支撑作用，所述箱座241与支架组件201固定连接，因而所述轴承外圈也可以固定在支架组件201上。
基于上述结构，本实施例的动作过程是这样的：驱动电机243输出的动力经输出端2431传送给一级齿轮244，一级齿轮244与二级齿轮245啮合，再通过第一同步带246传送给第一滚刷支撑轮组件247，驱动设置在其两侧的第一滚刷单元120旋转。与此同时，一级齿轮244通过第二同步带248将动力传送给第一同步带惰轮249，该第一同步带惰轮249又通过第三同步带250传送给第二滚刷支撑轮组件251，驱动设置在其两侧的第二滚刷单元220以相反方向旋转，实现清扫作业。
因此，本发明的原理在于：为了防止滚刷体太长导致其工作过程中震动大并出现 滚刷体变形的可能，将设置在不同轴线上的滚刷截成多个滚刷单元，且所有的滚刷单元均由同一个驱动单元来驱动。为了缩短单轴滚刷长度，在中间位置必然会被支撑部件占去一定空间，则同一侧滚刷的清扫长度就会缩短，采用双轴滚刷则可以克服上述缺点，将设置在两个相互平行的轴线上的两根长滚刷均截成长短不同的两个滚刷单元，使设置在两轴上的滚刷清扫盲区错位，使一轴上滚刷的清扫盲区被另一轴上滚刷的清扫区域覆盖，有效克服局部区域遗漏清扫的缺点。
当然，驱动单元的设置位置不一定必须设置在滚刷单元的中间，也可以采用两端分别驱动，在中间进行支撑。另外，两组滚刷单元如果直接通过轴承连接在支架组件上，那么驱动单元也可设置在两组滚刷的同一边侧，并通过多种方式使前后滚刷实现正反转，比如，背景技术中的US4850077，采用皮带交错的方式。
综上所述，本发明有效防止滚刷体太长导致其工作过程中震动大并出现滚刷体变形的可能，在同一轴线上设置多个滚刷单元，且该多个滚刷单元由同一驱动单元驱动；并结合两个相互平行的轴线，使多个然而为了缩短单根滚刷长度，在中间位置必然会被支撑部件占去一定空间，则同一侧滚刷的清扫长度就会缩短，此时，双滚刷系统可克服该缺点，将两侧的两根长滚刷截成长短不同的两根，使两侧滚刷上的清扫盲区错位，使一侧滚刷的清扫盲区被另一侧的滚刷清扫区域覆盖，有效克服局部区域遗漏清扫的缺点，结构简单清洁效率高。
