Description

手持式清洁设备
技术领域
本发明涉及一种手持式清洁设备，具体地但非排他地，涉及一种手持式真空吸尘器。更具体地，本发明涉及一种具有旋风分离器的手持式清洁设备。
背景技术
手持式真空吸尘器广为人知且已经被各种制造商制造和销售多年。通常，手持式真空吸尘器包括承装马达和用于将空气经由入口抽入到吸尘器中的风扇单元的壳体，和诸如过滤器或袋子这样的用于从进入气流中分离脏物和灰尘的分离装置。这种真空吸尘器的例子显示于GB1207278中。
手持式真空吸尘器近来已经被开发为并入有旋风分离系统，该系统能在使用过滤器或其他屏障装置去除细小颗粒之前从气流中去掉较大的脏物物体。这种装置的一个例子是由Black & Decker以商品名
Figure A200780027318D0003134049QIETU
销售的装置。并入旋风分离器的手持式真空吸尘器的又一例子显示于GB2035787A中。
利用旋风分离器的已有的手持式真空吸尘器缺点是，当仅仅用一个旋风器且带有过滤器和袋子时，过滤器需要维护，或者被倾斜或者被更换。维护过滤器失败会导致性能下降。因此，本发明的目的是提供一种手持式清洁设备，其能比已有手持式真空吸尘器更长时间地保持高性能。本发明的又一目的是提供一种比现有设备需要更少维护的手持式清洁设备。本发明的又一目的是提供一种手持式真空吸尘器，其能比当前的手持式真空吸尘器的设计产生和保持更高的吸入动力。
发明内容
本发明提供一种手持式清洁设备，包括脏空气入口、清洁空气出口和分离装置，该分离装置位于从空气入口到空气出口的空气流动路径中用于从空气流中将脏物和灰尘分离，该分离装置包括具有至少一个第一旋风器的旋风分离器，其中，旋风分离器还包括多个第二旋风分离器，布置为彼此平行且位于该或每个第一分离器的下游
通过设置具有平行的多个第二旋风器的旋风分离器，手持式清洁设备能不使用诸如过滤器或袋子这样障碍物来分离细小的脏物和灰尘颗粒，其中袋子或过滤器需要被维护来确保在长时间内保持高的性能。迄今被认为困难的是在手持式真空吸尘器中提供这类旋风分离器，因为这类旋风分离器占据的空间被认为很大且很重，而不适于手持机器。在手持式真空吸尘器中提供这类旋风分离器的进一步优点是，吸尘器随后能保持高的吸入动力，因为没有屏障类过滤器来导致吸入动力降低，以及随着时间而降低拾取能力。
优选的是，手持式清洁设备具有把手，且旋风分离器位于把手和脏空气入口之间。这提供了对于这类吸尘器使用者来说能很好平衡的结构。
优选的而是，旋风分离器大致平行于把手，且进一步优选的是旋风分离器大致处于竖立构造。这种特点有益于操纵和方便存放以及对位于旋风分离器中脏物和灰尘的清空。
在本发明的优选实施例中，设置一个第一旋风器且第二旋风器绕第一旋风器的轴线间隔开。这提供了紧凑的便于操作的平衡结构。优选的是，每个第二旋风设备有突出到第一旋风器中的端部，以便提供脏物收集能力和旋风分离器总体积之间的平衡。
附图说明
参见所附附图描述本发明的实施例，其中：
图1示出了根据本发明的手持式清洁设备；
图2示出了图1的设备的侧视图；
图3为形成图1设备一部分的旋风分离装置的纵向截面图。
具体实施方式
图1和2示出了手持式真空吸尘器10。手持式真空吸尘器10具有主体12，其承装马达和风扇单元(未示出)。主体12还包括诸如电池这样的电源14。把手14设置在主体12上，用于在使用中操纵手持式真空吸尘器10。旋风分离器100附接至主体12。脏空气入口18从旋风分离器100远离主体12的一部分延伸。刷子工具22可滑动地安装在脏空气入口18的远端。一组排气口24设置在主体12上，用于从手持式真空吸尘器10排出空气。
旋风分离器100位于主体12和脏空气入口18之间。结果，旋风分离器100位于把手16和脏空气入口18之间。旋风分离器100具有纵轴线26，该轴线沿大致竖立(upright)方向延伸，以使得轴线26以及旋风分离器100大致平行于把手16延伸的方向。
把手16的方位使得当使用者抓持把手16时，使用者的手以类似于抓持锯子时采用的方式类似的方式形成抓握。这确保了使用者的手腕在操纵手持式真空吸尘器10用于清洁目的时不会不必要地紧张。旋风分离器100定位为靠近把手16，这还降低当手持式真空吸尘器10处于使用中时施加于使用者手腕的力矩。把手16带有触发器形式的启动/关闭开关20，用于打开和关闭真空吸尘器马达。
形成手持式真空吸尘器10一部分的旋风分离装置100在图3中更详细地显示。旋风分离装置100包括第一旋风器102，其具有纵轴线X-X和壁104。入口110形成在壁104的上部。入口110与脏空气入口18连通并形成脏空气入口18和第一旋风器102的内部之间的连通路径。空气入口110与第一旋风器102相切地布置，以使得进入的空气被迫使绕第一旋风器102的内部遵循一螺旋路径前进。
基部116将第一旋风器102的一端关闭。基部116通过铰链118可枢转地安装在壁104的下端。基部116通过卡钩120保持在关闭位置(如图所示)。
罩121位于第一旋风器102的壁104之内。罩121包括圆柱壁122，该壁具有多个通孔123。罩121围绕第一旋风器102的出口124。出口124提供第一旋风器102和第二旋风器组件126之间的连通路径。凸缘128设置在罩121的基部处。凸缘128具有多个通孔129，这些通孔设计为允许空气穿过但捕获脏物和灰尘。
第二旋风器组件126包括彼此平行设置的多个第二旋风器130。在该实施例中，设置了六个第二旋风器130。第二旋风器130绕第一旋风器102的轴线X-X设置。第二旋风器的该设置是这样的，即第二旋风器130绕轴线X-X等角度地间隔。每个第二旋风器130具有切向设置的空气入口132和空气出口134。每个空气入口132和空气出口134位于相应第二旋风器130的第一端。锥形开口136位于每个第二旋风器130的第二端。每个旋风器130的锥形开口136的平面相对于相应其它旋风器130的纵向轴线(未示出)倾斜。第二旋风器130的锥形开口136与由位于罩121内的壁140限定的通道138相通。
每个第二旋风器130的第二端突出到第一旋风器102的内部。但是，每个旋风器130的第一端位于第一旋风器102的外壳的外部。在所示的方位中，每个第二旋风器130的下端突出到第一旋风器102的上端。入口110也设置在第一旋风器102的上端，以使得入口110位于旋风分离器100的第一和第二旋风器102、130重叠的区域内。由于第二旋风器130的第一端位于第一旋风器的外壳的外部，旋风分离器100的该区域位于旋风分离器100的上端和旋风分离器100的下端中间。把脏空气入口18和旋风分离器100在其中间部分连接对于手持真空吸尘器10的操纵是有益的且避免了该设备的最下端意外地敲击在远离已清洁区域的表面上
收集器142位于通道138的下端。收集器142包括截头锥形第一部分144和圆柱形第二部分146。收集器142的内部由基部116和收集器142的第一和第二部分144、146限定。
第二旋风器130的每个空气出口134都与管150连通。管150设置提供从旋风分离装置100进入手持真空吸尘器10的其它部分的气流通道。位于管150下游端处的是马达前过滤器152。马达前过滤器152包括诸如泡沫这样的多孔材料且还可包括细小过滤材料。马达前过滤器152设计为防止任何细小灰尘颗粒进入马达并引起它的损坏。
在使用时，当启动/关闭开关20被按下时，马达和风扇单元把携带脏物和灰尘的空气流抽入脏空气入口18，然后进入旋风分离器100。携带脏物和灰尘的空气穿过入口110进入旋风分离器100。由于入口110的切向设置，气口被强制沿着绕壁104的内部的螺旋路径行进。较大的脏物和灰尘颗粒通过绕壁104的旋风运动而被分离。这些颗粒然后被收集在第一旋风器102的基部116。
已部分清洁的气流然后向上返流到第一旋风器102的内部且经由罩121中的通孔离开第一旋风器102。一旦气流穿过罩121，其进入出口124且从那里被在各个第二旋风器130的切向入口132之间分配。每个第二旋风器130具有一直径，其小于第一旋风器102的。因此，与第一旋风器102相比，第二旋风器130能从已部分清洁的气流分离更小的脏物和灰尘颗粒。分离的脏物和灰尘经由锥形开口136离开第二旋风器130。此后，分离的脏物和灰尘向下经过通道138且进入收集器142。分离的脏物和灰尘最终停留在基部116上的收集器142的底部。
已清洁的空气然后向上朝第二旋风器130返流，穿过空气出口134离开第二旋风器130且进入管150。在穿过排气口24从真空吸尘器10排出前，已清洁的空气从管150经过，顺序穿过马达前过滤器152、马达和风扇单元和马达后过滤器。
通过释放卡钩以允许基部116绕铰链118枢转而使得分离的脏物和灰尘从旋风分离器100掉落，第一旋风器102和收集器142可被同时清空。这使得用户在方便的时间间隔把脏物和灰尘从旋风分离器100有效且可靠地排空。
本发明并不限于上述实施例的确切细节。例如，第一和第二旋风器的数量可改变，其设计的细节也可改变，诸如其锥形角度、轴线倾斜度和锥形开口倾斜度。被收集的脏物和灰尘可以其他方式释放，如通过完成第一旋风器102的下部的去除，且打开/关闭开关的位置可以改变。
