Description

一种内置电机滚刷机构及其吸尘器 技术领域
本发明涉及吸尘器领域，具体涉及一种内置电机滚刷机构及其吸尘器。
背景技术
现有的吸尘器样式一般分为两种：一种是使用交流电，产生负压吸力，纯粹用中空管的吸力来吸尘的吸尘器；一种是带有电动刷的，电动刷上的刷毛剥离、扬起地表的灰尘，继而进行收集。这两种吸尘器都是干式除尘，涉及不到用水。现有的电动刷往往是外部的电机通过齿轮、皮带驱动的，一般电机是与毛刷辊平行布置的，这样吸尘器头部整体的尺寸较大，难以对一些角落进行清洁。另外，现有的吸尘器主要利用转动的刷毛对地面的灰尘、杂物进行扫除，利用负压吸力对灰尘、杂物进行收集，但这依然不能应付所有地面的脏污状况。传统的家庭地面情节包括扫地与拖地，拖地能够带走地面的一些水溶性的污斑，传统的吸尘器的整个清洁过程是在干燥情况下进行的，难以对一些粘性脏污进行清除，还存在局限性。
发明内容
本发明要解决的问题在于提供一种内置电机滚刷机构及其吸尘器，电机位于抹布筒内部，节约尺寸，方便清洁墙边边缘。湿润的抹布能进一步提高清洁效果，出水、收集机构使用方便，减轻使用者劳动强度。
为解决上述问题，本发明提供一种内置电机滚刷机构及其吸尘器，为达到上述目的，本发明解决其技术问题所采用的技术方案是：
电机，为旋转电机；内筒，呈中空的圆柱状并包裹住电机；抹布筒，呈管状，抹布筒的圆周面上覆盖有抹布；出水机构，对抹布进行湿润；内筒、抹布筒同轴布置，抹布筒由电机驱动旋转。
采用上述技术方案的有益效果是：电机位于抹布筒内部，相比现有技术中独立于滚刷之外的电机，大大节约了空间，减少了吸尘器头部的尺寸，便于对墙边边缘进行清洁。也省去了现有技术中连接无动力滚刷所需要的齿轮、皮带等部件，节约了设备成本，减少了零部件数量，降低了设备故障率。内筒为电机起到定位、防水的作用，抹布筒为柔性的抹布提供了固定位置。湿润的抹布随电机转动，可以实现对地面的抛光清洁，优于人工拖地效果，清洁效果好。
作为本发明的进一步改进，电机的电机轴凸出于内筒并与抹布筒固定装配，电机的机身与内筒相对静止，抹布筒相对内筒旋转运动。
采用上述技术方案的有益效果是：确保电机置于抹布筒的内部，抹布筒又能相对于内筒旋转，使抹布具备旋转抛光的能力。
作为本发明的更进一步改进，出水机构设在抹布的外侧，出水机构包括控水槽板、盖板，盖板上具备出水口，出水口的出水方向与控水槽板相交。
采用上述技术方案的有益效果是：出水机构设置在外侧，布局设计较为方便，如果出水口只有一个，相比点布置的出水口，控水槽板对出水口中涌出的洁净水起到一定的引流作用，促使洁净水湿润整个抹布整体，而不是只湿润局部。
作为本发明的又进一步改进，控水槽板具备相互平行的第一槽板、第二槽板，以及垂直连接第一槽板、第二槽板的第三槽板，第一槽板、第二槽板、第三槽板围成引水槽，引水槽的开口方向与出水口的出水方向相反，第一槽板或第二槽板与盖板之间存在连通出水口与抹布的间隙。
采用上述技术方案的有益效果是：由第一槽板、第二槽板做两侧边，第三槽板做底构成的引水槽对出水口涌出的洁净水起到一定的阻挡作用，防止大量洁净水集中润湿靠近出水口处的抹布筒，即防止水大量集中在抹布筒的中部。引水槽将洁净水向两侧分流，当洁净水在流动、碰撞中越过第二槽板时，才会通过间隙对抹布筒进行润湿，保证了抹布筒轴线固定湿润均匀度，保证抹布筒的清洁效果。
作为本发明的又进一步改进，盖板的下方连接装配有滚刷底座，盖 板的两侧连接装配有滚刷定位盖，端头盖具备平行于抹布筒自身轴线方向的凹陷腔，滚刷定位盖上具备凸圆柱，凸圆柱位于凹陷腔内并与抹布筒连接，滚刷定位盖上具备斜切面，斜切面所在空间平面与抹布的轴端相交。
进一步的，控水槽板、盖板上均具备螺纹孔，两者对应的螺纹孔通过一个螺钉相连，所述出水机构还设有通过PWM脉冲宽度调制方法改变出水口出水流量的大小的水泵，通过微调控水槽板与盖板间隙的宽窄改变抹布单位时间内浸湿程度的大小且使得抹布表面可以均匀地被湿润。
采用上述技术方案的有益效果是：盖板与滚刷底座上下搭配，构成了一个吸尘器的头部，用于容纳滚刷和各种辅助设备。凹陷腔可以将轴承等设备设于抹布筒内侧，减少抹布筒两轴端的凸出尺寸，减小吸尘器头部的宽度。斜切面机构，收窄了吸尘器两侧端的厚度，收窄了吸尘器的头部，便于吸尘器头伸入较窄的区域清洁，尤其改善了对墙边边缘的清洁。
一种吸尘器，包括以上提到的任意一种内置电机滚刷机构。
采用上述技术方案的有益效果是：这种吸尘器的头部可以做得较小，方便清洁墙边边缘，还可以起到模拟拖把清洁的作用，清洁效果好。

具体实施方式
下面结合具体实施例，对本发明的内容做进一步的详细说明：
为了达到本发明的目的，一种内置电机滚刷机构，包括：电机1，为旋转电机；内筒2，呈中空的圆柱状并包裹住电机1；抹布筒3，呈管状，抹布筒3的圆周面上覆盖有抹布4；出水机构，对抹布4进行湿润；内筒2、抹布筒3同轴布置，抹布筒3由电机1驱动旋转。
图1是立体剖切视图，抹布4与抹布筒3之间可以是胶粘或者魔术贴贴合，抹布4也可以在抹布筒3上采用制绒等工艺复合为一个整体。抹布4自身可以选择柔软吸水的材质，例如精细纤维面料，或柔性无纺布材质，实际应用中，抹布4也可以是由一块矩形布对边可拆装的连接构成的。
在实际实施中，其工作原理可以采取如下方式，抹布筒3一端可转动的安装在滚刷底座的一侧上，例如通过轴承组件和滚刷底座连接，而内筒的一端固定连接在滚刷底座的另一侧上，内筒2套设在抹布筒3之中，二者同轴布置，抹布筒3的另一端与内筒2或滚刷底座的另一侧之间可转动连接(例如通过轴承)，电机固定设置在内筒的腔体中，其输出轴与抹布筒传动连接，这样，当电机启动后，其输出轴带动抹布筒转动。抹布筒上的抹布也跟随抹布筒一起旋转，出水机构向抹布提供使其湿润的水分，湿润的抹布在地板上旋转摩擦，可以清除粉尘等垃圾，并可以清除普通吸尘器难以清除的粘连在地板上的垃圾。
采用上述技术方案的有益效果是：电机位于抹布筒内部，相比现有 技术中独立于滚刷之外的电机，大大节约了空间，减少了吸尘器头部的尺寸，便于对墙边边缘进行清洁。也省去了现有技术中连接无动力滚刷所需要的齿轮、皮带等部件，节约了设备成本，减少了零部件数量，降低了设备故障率。内筒为电机起到定位、防水的作用，抹布筒为柔性的抹布提供了固定位置。本发明创造性的将湿润抹布和吸尘器结合为一有机整体，湿润的抹布随电机转动，可以实现对地面更高效的清洁，优于人工拖地效果，清洁效果好。
在一些实施方式中，电机1的电机轴凸出于内筒2并与抹布筒3固定装配(或通过变速组件传动连接)，电机1的机身与内筒2相对静止(两者固定连接、或紧配合连接、或通过花键连接等方式连接)，电机1驱动抹布筒3相对内筒2旋转。
如图1所示，电机1由内筒2、抹布筒3层层包裹，保证电机1与外圈抹布4上的水隔绝，保证电机1能在自身干燥的情况下持续作业。内筒2与抹布筒3之间具备空隙，以保证抹布筒3的灵活旋转。图1、图2中未显示出水机构。
在一些实施例中，如图2所示，内筒2、抹布筒3均是由两个独立的零件构成，内筒2的两个零件(或称为两个部分或部件)之间通过相互咬合的凸齿卡接(也可以采用螺纹连接。或在两个零件的连接端分别设置一个连接部，其中一个零件的连接部的外径，与另一个零件的连接部的内径相匹配，连个连接部之间进行嵌套连接，嵌套连接的紧密度根据需要来决定。或其他同轴的连接方式。)。抹布筒3之间也是通过相互咬合的凸齿卡接(也可以采用螺纹连接。或在两个零件的连接端分别设置一个连接部，其中一个零件的连接部的外径，与另一个零件的连接部的内径相匹配，连个连接部之间进行嵌套连接，嵌套连接的紧密度根据需要来决定。或其他同轴的连接方式。)。
在一些实施例中，内筒2、抹布筒3的两个零件之间的卡接接缝处的位置可以错开，进一步保证密封效果，也保证抹布筒3整体的结构强度。
采用上述技术方案的有益效果是：确保电机置于抹布筒的内部，抹布筒又能相对于内筒旋转，使抹布具备旋转的能力，旋转且湿润的抹布 可以提高清洁顽固污渍的能力，也具有抛光地板的作用。
在一些实施方式中，出水机构设在滚刷筒底座上并靠近抹布4的外侧，出水机构包括控水槽板6、盖板7，盖板7上具备出水口8，出水口8的出水方向与控水槽板6相交(出水口8与控水槽板6之间设有连接部，洁净水由出水口8流入控水槽板6中，经控水槽板6的引导，形成一个与抹布宽度一致的布水水流，使得整个抹布被均匀的布水湿润)。
采用上述技术方案的有益效果是：出水机构设置在外侧，布局设计较为方便，如果出水口只有一个，相比点布置的出水口，控水槽板对出水口中涌出的洁净水起到一定的引流作用，促使洁净水湿润整个抹布整体，而不是只湿润局部。
在一些实施方式中，如图7所示，实心箭头代表了洁净水的流动方向。控水槽板6具备相互平行的第一槽板10、第二槽板11，以及垂直连接第一槽板10、第二槽板11的第三槽板13，第一槽板10、第二槽板11、第三槽板13围成引水槽12，引水槽12的开口方向与出水口8的出水方向相反，第一槽板10或第二槽板11与盖板7之间存在连通出水口8与抹布4的间隙14。
采用上述技术方案的有益效果是：由第一槽板、第二槽板做两侧边，第三槽板做底构成的引水槽对出水口涌出的洁净水起到一定的阻挡作用，防止大量洁净水集中润湿靠近出水口处的抹布筒，即防止水大量集中在抹布筒的中部。引水槽将洁净水向两侧分流，当洁净水在流动、碰撞中越过第二槽板时，才会通过间隙14对抹布筒上的抹布进行润湿，保证了抹布筒上的抹布沿轴线方向有基本固定湿润均匀度，保证抹布筒的清洁效果。
在本发明的一些实施方式中，盖板7上还设有吸口9，吸口9、出水口8的自身轴线所确定的空间平面与抹布筒3自身轴线垂直并将抹布筒3两等分。
如图5所示，实心箭头的方向代表了污水、气流的进行方向。
在本发明的另一些实施方式中，抹布4与吸口9、控水槽板6接触，沿抹布4的旋转方向，抹布4从吸口9到控水槽板6的旋转角度为锐角。
采用上述技术方案的有益效果是：吸口虽然与出水口靠近设置，但其实随着抹布筒的转动方向，出水口中的水几乎在抹布筒上转动一周才会到达吸口的位置，使得洁净水对地表进行充分清洁后才会被收集。保证水的充分利用，人员操作简便，劳动强度低。
在本发明的一些实施方式中，控水槽板6、盖板7上各具备螺纹孔，控水槽板6、盖板7之间通过穿过螺纹孔的螺钉连接。
如图7所示，控水槽板6在与出水口8之间连接处设有连接部，出水口8在出水端具备膨大腔，控水槽板6的连接部设置在膨大腔内。图7中的实心箭头方向，间隙14具备多处弯折部。
如图5所示，吸口9与抹布4之间设有一个吸气腔17，吸气腔17由抹布4向吸口9方向自身尺寸收窄，引导气流、污水进入吸口9。
控水槽板、盖板上均具备螺纹孔，两者对应的螺纹孔通过一个螺钉相连。既实现了两者的装配，又可以通过调节两者的螺纹孔在螺钉上的位置来实现控水槽板与盖板的位置微调，继而改变间隙的宽窄，从而调节出水的流量效果。当然流量的调整主要还是需要依靠出水机构中设置的水泵和/或电控阀来完成。现有技术的要不就是出水流量大小不可调节，要不就是出水通过喷射不能均匀润湿地面或者抹布。
在一些实施例中，出水机构的控水槽板、盖板上均具备螺纹孔，两者对应的螺纹孔通过一个螺钉相连，所述出水机构还设有通过PWM脉冲宽度调制方法改变出水口出水流量的大小的水泵，通过微调控水槽板与盖板间隙的宽窄改变抹布单位时间内浸湿程度的大小且使得抹布表面可以均匀地被湿润。好处：一，采用PWM脉冲宽度调制方法调节出水口出水流量的大小，根据所清洗地面的不同可以调整到相应合适的流量；二，通过微调控水槽板与盖板间隙的宽窄改变抹布单位时间内浸湿程度的大小且使得抹布表面可以均匀地被湿润。通过一和二两种方法的组合应用，显著地提高了清洁的效果，不仅节约了水资源，而且使地面清洗得更加干净。
在本发明的一些实施方式中，抹布筒3的轴端设有端头盖5，端头盖5具备凸起的环状筋，环状筋顶端的直径大于抹布筒外壁所对应的直径。
如图3所示，盖板7、控水槽板6上分别具备四个螺纹孔，若干个螺纹孔在控水槽板6上的连线排布方向与控水槽板6自身长度平行。
凸起的环状筋与抹布筒连接紧密，防止抹布筒在作业过程中发生轴向位移。
在本发明的一些实施方式中，盖板7的下方连接装配有滚刷底座15，盖板7的两侧连接装配有滚刷定位盖16，端头盖5具备平行于抹布筒3自身轴线方向的凹陷腔，滚刷定位盖16上具备凸圆柱18，凸圆柱18位于凹陷腔内并与抹布筒3连接，滚刷定位盖16上具备斜切面19，斜切面19所在空间平面与抹布4的轴端相交。
盖板7的空间状态相对稳定，通过盖板7、滚刷定位盖16、内筒2、电机1的依次连接，保证电机1的位置状态。
采用上述技术方案的有益效果是：盖板与滚刷底座上下搭配，构成了一个吸尘器的头部，用于容纳滚刷和各种辅助设备。凹陷腔可以将轴承等设备设于抹布筒内侧，减少抹布筒两轴端的凸出尺寸，减小吸尘器头部的宽度。斜切面机构，收窄了吸尘器两侧端的厚度，收窄了吸尘器的头部，便于吸尘器头伸入较窄的区域清洁，方便清洁墙边边缘。
一种吸尘器，包括以上提到的任意一种内置电机滚刷机构。
采用上述技术方案的有益效果是：由于电机内置于内筒中，这种吸尘器的头部可以做得较小，方便清洁死角，还可以起到模拟拖把清洁的作用，清洁效果好。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并加以实施，并不能以此限制本发明的保护范围，凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围内。
