Description

地刷以及吸尘器具 技术领域
本发明具体涉及一种地刷以及包含该地刷的吸尘器具。
背景技术
吸尘器已在普通家庭中得到广泛使用，其工作原理基本相同，都是通过一个电风机驱使空气高速旋转，因此产生负压和气流，气流通过一定的引导风道与地面接触，把地面的灰尘吸入集尘装置。地刷是吸尘器跟地面直接接触的部件。
现有地刷的吸尘效率已达到一个瓶颈，为提高吸尘器的效率，现有的常规手段是加大吸尘功率，进而提高吸尘效率。但采用该方法，仍无法克服一个缺陷——在吸尘器除尘时，在倒退运动时，吸尘器的地刷有从地板表面升起的危险，并且地刷自身有相对于地板表面倾斜的危险，这对吸尘具有消极影响。
CN 101513335B威赛提供一种地刷，其驱动机构含有连接部，其上设有导向凹槽，另有水平绞轴的一端设于导向凹槽中，当地刷前进或者后退时，水平绞轴能在导向凹槽内上下滑动，使得地刷与地板的作用力发生改变，因而便于推进或者后退，且推进或者后退过程中，滚轮始终贴紧地面。虽然该专利文件克服了上述缺陷，但这种结构比较复杂，相较于现有技术增加了零部件，提高了成本，也导致了加工的复杂程度，加大了维修难度。
发明内容
本发明是为了解决上述问题而进行的，目的在于提供一种地刷以及包含该地刷的吸尘器具。
本发明为了达到以上的目的，采用了以下结构：
<结构1>
本发明提供了一种地刷，用于跟吸尘器的风管配套使用进行地面清洁，具有这样的特征，包括：主体组件，包含：底板，设置有吸入气体的吸口槽以及与风管连通的风口；以及上盖，与底板形成一个主体腔；风道组件，包含：导风盖，与底板连接，形成用于进气的吸口；软管，前端与底板的风口连接，用于引导风 从风口进入；弯管套，前端与软管的后端连接，用于防止漏气；弯管，前端与弯管套的后端连接，后端与风管连接；软管盖板，设置在上盖位于软管的上方的位置处，前端通过第一转轴跟导风盖的上部转动连接；以及弯管座下盖，位于软管与弯管套的连接处的下方，与软管盖板的后端固定连接，弯管套通过第二转轴与弯管座下盖转动连接；以及滚轮组件，位于主体组件后方，包含至少两个滚轮，分别位于软管的左右两侧，与弯管座下盖可转动地连接，其中，当地刷位于水平面上并且两个滚轮贴紧地面时，第一转轴与第二转轴分别与地面平行，第一转轴到底板所在的平面的距离被设为D1，第二转轴到底板所在的平面的距离被设为D2，第一转轴高于第二转轴，D1＝D2+X，X为4.3～6.3mm范围内的任意值。
<结构2>
进一步，本发明还提供了一种吸尘器具，具有这样的特征，包括：风管；以及与该风管配套的地刷，其中，地刷为<结构1>中的地刷。
发明的作用与效果
根据本发明所涉及的地刷以及包含该地刷的吸尘器具，因为设置有第一转轴和第二转轴，且在水平放置状态中，第一转轴到底板所在的平面的距离被设为D1，第二转轴到底板所在的平面的距离被设为D2，D1＝D2+X，X为4.3～6.3mm范围内的任意值，所以，本发明的地刷以及包含该地刷的吸尘器具漏气小，能量转化率高，除尘效率高。另外，第一转轴位置合理，在地板和地毯上推拉都比较容易，而且回拉时不会跳动。而且本发明的地刷以及包含该地刷的吸尘器结构比较简单，生产与维护成本都比较低，容易推广。

<实施例>
在本实施例中，地刷10通过风管与吸尘器具的本体连接。
图1是本发明的实施例中地刷的立体图。
如图1所示，在本实施例中，地刷10包括主体组件11、风道组件12以及滚轮组件13。
图2是本发明的实施例中地刷的分解视图。
如图2所示，主体组件11包含底板33、上盖21、升降板25以及升降开关组件14。
图3是本发明的实施例中地刷的仰视图。
如图3所示，底板33底面上设置有静电条38、吸口槽55，吸口槽55从底板下方的中部一直延伸到底板的左右两侧。
如图2所示，上盖21与底板33通过螺丝40固定在一起，形成一个主体腔。上盖21和底板33围成的主体腔(图上没有显示)内设置有升降板25以及升降开关组件14。升降板25位于底板33上方。
图4是本发明的图3的C-C剖面视图(剖开并翻转180度).
如图2和图4所示，升降板25左右两侧分别设有一个圆孔26，上盖21内侧左右两边分别设有一个上盖导柱56，上盖导柱56穿过升降板25上对应的圆孔26，跟底板33左右两侧带有弹簧32的中空的底板导柱34分别连接。升降板25下方设有两根毛条39，毛条39的一端固定在升降板下表面，另外一端指向地面。
升降开关组件14位于升降板25的上方，用于推动升降板移动控制升降板的高低位置，使得升降板25下方的毛条39从吸口槽的前后方边缘区域伸出或从底板下方向主体腔收缩，升降开关组件14包含脚踏板22、联动杆24、第一摆臂23-2以及第二摆臂23-1。
本实施例中，脚踏板22位于地刷的左侧，外露在上盖21表面。用户可根据需要按压脚踏板22或扳起脚踏板22。
主体腔内部的左右侧分别设有第一摆臂23-2和第二摆臂23-1。第一摆臂23-2和第二摆臂23-1之间通过联动杆24相连。第一摆臂23-2和第二摆臂23-1相互平行，位于同一平面中。
第一摆臂23-2向主体腔内部伸展，第一摆臂23-2下方的左支撑线61靠近升降板25左方的上表面。在脚踏板22被按压下去时，第一摆臂23-2下方的左支撑线61向下运动，并压迫升降板25的左支撑面59，同时，联动杆24跟随脚踏板22向后转动，带动第二摆臂23-1向下运动，第二摆臂23-1下方的右支撑线60压迫升降板25的右侧的右支撑面58，这样使得升降板25的左右两侧同时 受到向下的压力，所以弹簧32向底板33收缩。当弹簧32被压缩时，升降板25下降靠近底板33，并将毛条39伸出底板。在脚踏板22被扳起时，弹簧32舒展，升降板25上升远离底板33。在弹簧32自然状态下，底板33跟水平地面贴近，升降板25跟水平地面平行。
此外，当弹簧32向底板33收缩时，固定在升降板25上的两根毛条39向底板33下方伸出，与地面接触，使得底板33与地面的距离加大，确保毛条39而不是底板33与地面直接接触。这时地刷进入地板除尘状态，向下伸展的毛条可以保护地板表面避免被地刷刮伤。本实施例中，底板33上设有两根毛条39，也可以根据需要只保留前方毛条，把后方毛条改用橡胶条或者其它柔性带状元件。
当该地刷10用于地毯除尘时，将脚踏板22向上扳起，第一摆臂23-2和第二摆臂23-1都摆在后方，与升降板25上的支撑面脱离接触，原来施加在升降板25上方左右两侧的压力被撤销，弹簧32向上复位，带动两根毛条39向主体腔内部收缩，使得底板33上的吸口槽55得以靠近地毯表面。
如图2所示，风道组件13包含导风盖27、软管44、弯管套45、弯管50以及弯管座下盖41。
图5是本发明的实施例中地刷的俯视图；图6是本发明的图5的A-A剖面视图。
如图2、图5、图6所示，导风盖27下边缘的左边31和右边30与底板33上吸口槽55的右边35和左边36通过超声波焊接的方式密闭连接，导风盖27的后方与底板33上的风口37通过超声波焊接的方式密闭连接。导风盖27与底板33连成一体，形成用于进气的吸口，引导气流从地面流向吸尘器，形成导风区域57。导风区域57的迎风表面平滑以便顺畅进风。导风盖27与底板33也可以通过注塑方式一次成型。
图7是本发明的图5的B-B剖面视图。
如图7所示，毛条39从底板33向下伸出之后，为了保证左右两侧毛条的外露高度相同，进而保证升降板上表面水平，可以把第二摆臂23-1向下延伸的长度设计成比第一摆臂23-2向下延伸的长度长0.3毫米左右，或者保证左第二摆臂长度相同，但把升降板25上方的右支撑面58设计成比左支撑面59高0.3毫米左右。即，当地刷处于水平状态时，第一摆臂与升降板的接触位置，比第二摆臂 与升降板的接触位置低，两个接触位置的中心点的连线与水平面的夹角为0.04度。这个角度虽然比较小，但可以使得毛条从底板向下伸出时，毛条左右两侧都能接触到地面，因而提高在地板上的除尘能力。如果左右接触面没有这样的倾角，那样也可以使用，只是在地板上的除尘能力要相对差一些。
如图4所示，导风盖27的前端与底板33的连接处的横截面的长度为285mm。
图8a是导风盖的结构示意图，图8b、图8c、图8d分别为图8a中导风盖的A-A，B-B和C-C剖视图。
如图8a所示，导风盖总长度约152.70毫米。
如图8b所示，从导风盖27的轴向方向剖开，得到的截面的形状为：从上至下分别由半径为R1(67.10mm)的圆弧、半径为R2(30.27mm)的圆弧以及半径为R3(49.48mm)的圆弧相互内切而形成的弧形，切点分别为E和F。
如图8c所示，在离导风盖27的轴向方向23mm的位置剖开，得到的截面的形状为：从上至下分别由半径为R4(6.40mm)的圆弧、半径为R5(23.32mm)的圆弧、半径为R6(14.10mm)的圆弧以及半径为R7(36.41mm)的圆弧相互内切而形成的弧形。顶部起始位置为长4.53毫米的线段，该线段与R36.41mm的圆弧相切，切点为G，R14.10mm的圆弧和R36.41mm圆弧以及R23.32mm的圆弧分别内切，切点分别是H和I。R6.40mm的圆弧内切于R23.32mm圆弧，切点为J。
如图8d所示，在导风盖27远离底板18毫米的位置剖开，得到的截面的形状为左右对称的类V字形弧线，图8d所示的虚线为对称中心线。该类V字形弧线的一半边由：从上至下分别由长E1(19.79±2毫米)并且与水平面呈α夹角的线段、半径为R8(118.96mm)的圆弧、半径为R9(60.79mm)的圆弧以及半径为R10(27.69mm)的圆弧相互内切而形成的弧形两侧边缘都有长19.79±2毫米的线段Q1Q2，Q1Q2与水平面夹角α均等于16.62度，线段Q1Q2与圆弧R118.96mm相切，切点为Q2，圆弧R118.96mm与圆弧R60.79mm外切于B点，圆弧R60.79mm与圆弧R27.69mm内切于C点。
上述圆弧的半径公差为±2毫米。该地刷底部进气口迎风面的形状模仿海螺的内孔，气流比较顺畅。
如图2所示，软管44的前端与底板33上的风口37密封连接，软管44后端 与弯管套45密封连接，
软管44的上方设有软管盖板51-1，下方设有弯管座下盖41，软管盖板和弯管座下盖通过螺丝固定连接，从上下两个方向包围软管44。导风盖27上方设有左右两个耳孔28和29，当地刷10处于自由状态时，两个耳孔28和29的中心连线与地面平行。软管盖板51-1的前端两侧均设有第一转轴52，分别嵌入导风盖27上方两侧的两个耳孔28和29中，使得软管盖板51-1受力之后能绕导风盖27上方两个耳孔的中心连线转动。软管盖板51-1绕第一转轴52转动的自由度为33±5度。
弯管座下盖41的左右两侧分别设有一个U形槽42，弯管套45的左右两侧分别设有一个沿水平方向伸展的第二转轴47，分别装在两个U形槽42中。弯管套45能绕第二转轴47向前或向后转动。
弯管座下盖41的左右两侧分别设有一个圆孔43，左右两个滚轮53的转轴54分别嵌入圆孔43中。两个滚轮53均位于主体组件11后方，且分别位于软管44的左右两侧。左右两个滚轮53能在前后方向自由转动。滚轮53的直径可根据需要选择为63～67毫米中任意值。
当地刷处于吸尘状态并且两个滚轮贴紧地面时，第一转轴与第二转轴相互之间平行，并且都平行于地面。第二转轴的轴线离地高度约32.5毫米，第一转轴轴线离地高度约37.8毫米。试验发现，前后两个转轴在垂直方向的高度差控制在4.3～6.3毫米时，在地毯上吸尘时的推力最小，用户体验最好。
弯管套45尾部设有两个通孔46，弯管50前端设有环形卡槽51-2。环形卡槽51-2外设置有C形卡圈48。C形卡圈48的内壁的左右两侧设有向内凸起的卡筋49。弯管50嵌入弯管套45时，通孔46和卡槽51-2相对，C形卡圈48上的卡筋49穿过通孔46嵌入卡槽51-2中，将弯管50和弯管套45连接在一起。
另外，弯管50跟弯管套45可以如上所述通过外卡圈连接，也可以将弯管50嵌入弯管套45内。弯管50上的凹槽中装上C形金属圈，弯管套45的对应位置的内壁设有凹槽，C形金属圈随弯管50挤入弯管套45内壁凹槽并舒展开来之后，弯管50就能在弯管套45内自由转动，但不能前进或者后退。
弯管50是该地刷的出气口，也是跟吸尘器的风管的接口。吸尘器的风管可以为硬质延长管或者吸尘软管。
图9为地毯除尘状态下往前推的示意图，两个滚轮贴紧地毯表面(此时毛条收缩在主体腔内)；图10为地毯除尘状态下往后拉的示意图，两个滚轮离开地毯表面(此时毛条收缩在主体腔内)；图11为地板除尘状态下往前推的示意图，两个滚轮贴紧地板表面(此时毛条从底板下表面向下伸出)；图12为地板除尘状态下往后拉的示意图，两个滚轮离开地板表面(此时毛条从底板下表面向下伸出)。
如图9和图11所示，吸尘器通电之后，在地面上向前推进该地刷时，两个滚轮53贴紧地面。如图10和图12所示，往后拉动时，两个滚轮53跟随弯管套45一起离开地面。
实施例的作用与效果
根据本实施例所涉及的地刷以及包含该地刷的吸尘器具，因为设置有第一转轴和第二转轴，且在水平放置状态中，第一转轴到底板所在的平面的距离被设为D1，第二转轴到底板所在的平面的距离被设为D2，D1＝D2+X，X为4.3～6.3mm范围内的任意值，所以，本实施例的地刷以及包含该地刷的吸尘器具漏气小，能量转化率高，除尘效率高。此外，第一转轴位置合理，在地板和地毯上推拉都比较容易，而且回拉过程中不会跳动。而且本发明的地刷以及包含该地刷的吸尘器结构比较简单，生产与维护成本都比较低，容易推广。另外，底板上模仿海螺内孔的风道设计保证了通风顺畅，并降低了气流噪音。
上述实施方式为本发明的优选案例，并不用来限制本发明的保护范围。
