Description

表面清洁装置
技术领域
本实用新型涉及表面清洁装置。更特别地，本实用新型涉及气旋式表面清洁装置。 
背景技术
下文并非承认下面所讨论的任何内容是现有技术或者是本领域技术人员的公知常识的一部分。 
气旋式真空吸尘器采用了具有配套的污物收集腔室的一个或更多旋流器。污物收集腔室在旋流器腔室的底部形成。盘片或分割件可以定位在旋流器壳体中，从而将旋流器壳体分割为上旋流器腔室和下污物收集腔室。同样公知的是，将污物收集腔室定位到旋流器壳体之外，例如环绕着旋流器腔室。 
在上述公知的气旋式真空吸尘器中，位于旋流器腔室的端部处的盘片或分割件构造成提供了均匀长度的间隙，该间隙作为旋流器腔室的污物出口。在某些构造中，例如如果这样的旋流器被定向成非竖直的，在旋流器腔室的周边设置恒定长度的间隙可能导致污物聚集，或者导致离开污物出口的污物和垃圾的其它的非期望的分配。 
实用新型内容
本实用新型所要解决的技术问题是：现有技术的气旋式真空吸尘器，在其旋流器被定向成非竖直状态时会导致污物聚集，或者导致离开污物出口的污物和垃圾的其它的非期望的分配。 
所提供的下述实用新型内容用于向读者介绍随后的更为具体的讨论。本实用新型内容并不意在限制或限定权利要求。 
根据一个宽泛的方面，所提供的表面清洁装置利用具有开放端部的旋流器，其中所述开放端部包括所述旋流器的污物出口。板定位为面对所述开放端部，并且优选为具有面对所述开放端部的平坦表面。 例如，所述板可以位于垂直于纵向轴线的平面中，并且可以与所述开放端部隔开，所述纵向轴线经过旋流器腔室而延伸。相应地，在所述板和所述开放端部之间设置间隙，并且所述间隙限定所述旋流器的污物出口。根据这一方面，所述间隙具有不一致的长度。 
例如，所述旋流器壳体可以具有可变长度。具有较短长度的部分限定具有增高高度的间隙。可替代地或者此外，所述板可以在所述板的面对所述旋流器的开放端部的一侧上具有侧壁。所述侧壁可以局部地围绕所述板延伸。所述壁的高度可以是不变的或者可以是可变的。 
所述侧壁优选地设置在所述板的周边上。所述板的直径优选地大约与所述旋流器的开放端部的直径相同。 
在某些实施方案中，所述板的侧壁具有不变的长度。在其它实施方案中，所述板的侧壁具有可变的长度。 
在某些实施方案中，所述旋流器的侧壁在所述开放端部具有第一端部，所述第一端部具有周边(perimeter)，所述间隙具有第一部分和第二部分，所述第二部分所具有的第二长度大于所述第一部分所具有的第一长度。所述第一长度和所述第二长度可以是不变的。可替代地，所述第一长度和所述第二长度可以是可变的。 
在某些实施方案中，所述第一部分和所述第二部分中的一个部分延伸达所述周边的210°。例如，所述第二部分可以延伸达所述周边的210°。在其它实施方案中，所述第二部分延伸达所述周边的240°。 
根据另一个宽泛的方面，提供了一种表面清洁装置。所述表面清洁装置包括气流通道，所述气流通道从脏空气入口延伸到洁净空气出口。吸气电动机设置在所述气流通道中。旋流器设置在所述气流通道中。所述旋流器包括空气入口、空气出口、开放端部、纵向轴线以及纵向延伸的侧壁。所述侧壁具有可变的长度。污物收集腔室与所述开放端部流体连通。 
在某些实施方案中，所述侧壁的第一部分长于所述侧壁的第二部分。 
在某些实施方案中，所述侧壁在所述开放端部处具有第一端部，所述第一端部具有周边，且所述第一部分包括达到所述周边的240°，所述第二部分包括达到所述周边的120°。 
在某些实施方案中，所述表面清洁装置进一步包括面对所述开放端口的板。所述板可以与所述表面清洁装置的前端部壁隔开。所述污物收集腔室的第一部分可以设置在所述板和所述前端部壁之间。优选地，所述污物收集腔室的第二部分环绕所述旋流器的至少一部分。 
根据另一个宽泛的方面，提供了另一种表面清洁装置。所述表面清洁装置包括气流通道，所述气流通道从脏空气入口延伸到洁净空气出口。吸气电动机设置在所述气流通道中。旋流器设置在所述气流通道中。所述旋流器包括空气入口、空气出口、开放端部、纵向轴线以及纵向延伸的侧壁。板设置为具有面对所述开放端部的旋流器侧面。所述板定位为在所述板和所述旋流器的开放端部之间限定间隙。所述板具有板侧壁，所述板侧壁向着所述开放端部延伸。污物收集腔室与所述开放端部流体连通。 
在某些实施方案中，所述板侧壁局部地围绕所述板延伸。在某些实施方案中，所述板的侧壁具有不变的长度。在其它实施方案中，所述板的侧壁具有可变的高度。 
本文描述的任意一种表面清洁装置都可以包括便携真空吸尘器，并且更优选地为手持真空吸尘器。所述便携真空吸尘器可以能够拆卸地安装到立式真空吸尘器。 
应当意识到，实施方案可以包含实例中展示的一个或更多特征。 
以下结合本实用新型的结构说明其有益的技术效果：与现有技术的气旋式真空吸尘器相比，由于将所述间隙设置成可变的长度，其几何形状会影响到空气流并进而影响到离开旋流器腔室的污物的分配；设置可变的长度的间隙可以帮助对离开旋流器腔室的污物进行更好的分配，这可以在污物收集腔室中产生更大的储存容积。

具体实施方式
下面将要描述的各种装置或方法提供了每一个所要求发明的实例。下面描述的实例并非限制任何所要求的发明，并且任何所要求的发明可以覆盖下面未描述的方法或装置。所要求的发明并不限于具有下面描述的任何一种装置或方法的所有特征的装置或方法，也不限于下面描述的多个或所有装置的共同特征。下面描述的装置或方法可以不是任何所要求的发明的实施方案。 
参照图1至7，显示了表面清洁装置100的第一实例。优选地，表面清洁装置100(在本文中也称为吸尘器100或真空吸尘器100)为便携真空吸尘器100，例如所示的手持真空吸尘器100。手持真空吸尘器100通过抓持并操纵手柄102而沿着待清洁表面可移动。在替代实施方案中，表面清洁装置100可以为另一种类型的表面清洁装置，例如手杖式吸尘器(stick-vac)、立式真空吸尘器或者罐式真空吸尘器(canistervacuum cleaner)。 
示例性实施方案是手持真空吸尘器。用于旋流器以及面对的板(在两者之间的间隙具有不一致的高度)的设计可以使用在任何旋流式清洁装置中。如果在诸如手持真空吸尘器的便携表面清洁装置中使用该特征，那么该便携表面清洁装置可以为任意设计。例如，如所示例的那样，真空吸尘器包括上部部分104、下部部分106、前部108和后部110。在所示实例中，手柄102设置在上部部分104处。在替代实例中，手柄102可以设置在真空吸尘器100的其它位置，例如设置在后部110处，并且手柄102可以为任意设计。真空吸尘器100可以为各种配置(例如，旋流器单元和吸气电动机可以具有不同定位和取向，并且可 以具有不同的旋流器单元，这些旋流器单元可以包括一个或更多旋流器以及一个或更多过滤器)，并且可以使用任意类型的管口或者任意位置的管口。 
在所示实例中，真空吸尘器100包括管口112和旋流器单元114，管口112可以为任意设计，旋流器单元114与管口112一起形成真空吸尘器100的表面清洁头116。如实例所示，表面清洁头116优选为设置在真空吸尘器100的前部108处。 
管口112接合待清洁表面，并且包括脏空气入口118，脏空气经过脏空气入口118而被抽取到真空吸尘器100内。气流通道从脏空气入口118延伸到吸尘器100的洁净空气出口120。在所示实例中，洁净空气出口120位于吸尘器100的后部110处。 
旋流器单元114设置在脏空气入口118下游的气流通道中。在所示实例中，旋流器单元114包括一个旋流器122和一个污物腔室124，旋流器122定位在气流通道中。在替代实例中，旋流器单元110可以包括多于一个旋流级，其中每一个旋流级包括一个或更多旋流器以及一个或更多污物腔室。相应地，各个旋流器可以平行摄者和/或顺次设置。 
在所示实例中，管口112定位在真空吸尘器100的下部部分106处。优选地，如实例所示，管口112定位在真空吸尘器100的底部处，并且优选地定位在旋流器单元114之下。相应地，如实例所示，管口112可以位于旋流器单元114的下表面117上。在特别优选的设计中，管口的上壁可以为旋流器单元114的下壁。如图6所示，污物腔室124环绕旋流器122的下部部分。相应地，管口112的上壁可以是污物腔室的下壁的一部分。应当意识到，如果污物腔室124并不围绕旋流器122的下部部分延伸，那么管口112的上壁可以是旋流器122的下壁的一部分。 
优选地，在所示实例中，管口112固定地定位在真空吸尘器100的下部部分106处。也即，管口112相对于真空吸尘器100的其余部分不是可移动的(例如，可旋转的)，并且被固定在真空吸尘器100的下部部分106处。 
如图3和5所示，管口112具有宽度WN，并且旋流器单元114 具有宽度WC。在所示实例中，WN和WC大致相等。该设计的优点是，管口可以具有基本与手持真空吸尘器本身同样宽的清洁路径。 
优选地，管口112包括气流腔室，其中该腔室的下表面的至少一部分(并且优选为大部分)是开放的。在替代设计中，管口可以包括下壁，该下壁使下端部闭合。相应地，管口112可以为不同设计，并且可以是开放侧通道(open sided passage)或者是闭合通道(closedpassage)。 
管口112还可以与旋流器单元114的另一个零件共享公共壁。如图7中的实例所示，管口112包括上管口壁126，该上管口壁126限定气流腔室136的闭合上端部。在所示实例中，上管口壁126包括旋流器单元的壁115的下部部分119。 
优选地，一个或更多悬垂壁128从上管口壁126向下延伸。悬垂壁优选基本为U形。在一个实施方案中，悬垂壁设置在开口138的后面。在其它实施方案中，可替代地或另外地，悬垂壁可以设置在开口138的侧向侧面上。优选地，悬垂壁设置在开口138的每一个侧向侧面上并且设置在开口138的后面。另外，悬垂壁128可以延伸基本到达前端部108的距离，并且优选地，悬垂壁128实质上延伸到前端部108整个距离。悬垂壁可以是连续的以限定如图所示的单个壁，或者可以是不连续的。悬垂壁优选为刚性的(例如，与旋流器单元114整体模制而成)。然而，它们可以是柔性的(例如，鬃毛(bristle)或橡胶)或者可移动地安装到旋流器单元114(例如，铰接地安装)。 
优选地，当手持真空吸尘器置于待清洁表面上时，悬垂壁128的下端部132在处于清洁中的表面之上而隔开。如图6中的实例所示，当真空吸尘器100位于地板F上时，悬垂壁128的下端部132在地板之上隔开距离H。优选地，距离H为从0.01至0.175英寸，更优选地，距离H为从0.04至0.08英寸 
悬垂壁的高度(在上管口壁126和下端部132之间)可以改变。在某些实例中，悬垂壁的高度可以在大约0.05至大约0.875英寸之间，优选地在大约0.125至大约0.6英寸之间，更优选地在大约0.2至大约0.4英寸之间。悬垂壁的高度可以改变，但优选地是不变的。 
如实例所示，U形的开放端部限定了管口112的开放侧130，并且 形成吸尘器100的脏空气入口118。在所示实例中，开放侧130设置在管口112之前。使用时，当可选轮135与表面接触时，开放侧130位于待清洁表面(例如，地板F)之上并且毗邻待清洁表面。优选地，悬垂壁128的下端部132在地板F之上隔开。相应地，部分空气可以通过穿过悬垂壁132之下而进入管口112。在这样的情况下，主要空气经由开放侧130进入管口112，从而脏空气入口118为主要空气入口，其中次要空气入口位于悬垂壁128之下。在所示实例中，悬垂壁128的下端部132限定管口112的开放下端部134。开放下端部134优选为延伸到吸尘器108的前部108，并且与开放侧130会合。 
使用时，示例性的管口具有面对待清洁表面的开放下端部134。在所示实例中，多个轮135安装到悬垂壁128，并且延伸为低于悬垂壁128的下端部132。相应地，使用时，当轮135与表面接触时，悬垂壁128的下端部132与待清洁表面隔开，并且在悬垂壁128的下端部与待清洁表面之间的空间形成真空吸尘器100的次要脏空气入口。应当意识到，轮135是可选的。优选地，轮135定位在经过管口112的气流路径之外，例如，由悬垂壁128向外的侧向上。优选地，设置有一对前轮135。优选地，轮设置为毗邻前部108。可选地，可以设置一个或更多后轮108。在替代实施方案中，可以不设置轮。 
管口112的上管口壁126、悬垂壁128和开放下端部134限定管口的开放侧气流腔室136。使用时，当轮135与水平表面接触时，管口112和气流腔室136基本水平延伸，并且优选地沿着管口轴线113沿直线延伸(参见图7)。 
开口138设置在上管口壁126中，并且与气流腔室136连通。开口138可以为任意尺寸和配置，并且处于上管口壁126中的不同位置处。使用时，当轮135与表面接触时，开口138面对待清洁表面，空气进入脏空气入口118，水平穿过气流腔室136，并且穿行到开口138内。开口138与旋流器入口通道139连通，旋流器入口通道139与旋流器122的空气入口140连通。 
参考图5和6，旋流器122包括纵向延伸的侧壁142。在所示实例中，纵向延伸的侧壁142基本为圆柱形。旋流器腔室位于腔室壁142内部。旋流器122沿着纵向轴线123延伸。优选地，如图所示，轴线 123平行于管口轴线，并且在使用吸尘器100且轮135位于表面上时，轴线123基本水平地延伸。 
旋流器122进一步包括空气入口140和空气出口145。旋流器空气入口和旋流器空气出口可以为本领域公知的任意配置。旋流器122进一步包括开放端部147。开放端部147包括旋流器122的污物出口146。 
如实例所示，旋流器空气入口140由腔室壁142中的孔隙限定。如图5所示，入口通道139配置为使得空气以相切流动路径进入旋流器122，例如通道139可以是弓形的。空气沿旋流器中的旋流路径行进，并且空气中的污物从空气中分离。空气经由出口通道144离开旋流器，出口通道144与出口145连通。从空气中分离的污物经由污物出口146离开旋流器，并且进入污物腔室124，污物出口146由开放端部147限定。 
如图6中的实例所示，护罩(shroud)174可以设置为毗邻出口通道144，与出口通道144的入口176隔开并面对。护罩174可以经由支腿178安装到旋流器122。在所示实例中，护罩174和支腿178形成组件182，组件182可拆卸地安装在旋流器122中。在某些实例中，网罩可以围绕支腿178安装。护罩174可以为任意设计。 
正如上文所注意到的，旋流器122的开放端部147与污物腔室124连通。在所示实例中，污物腔室124包括两部分。第一部分148设置在污物出口146之前。第二部分150与旋流器122同心，并且环绕旋流器122的至少一部分。第二部分150的下部分152在旋流器之下。如实例所示，管口112定位在第一部分148和下部分152之下。
