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。更具体地说，本发明涉及一种手持式真空吸尘器。 
背景技术
手持式真空吸尘器例如可从GB 1 207 278中得知。该文件披露了一种手持式真空吸尘器，其包括具有空气入口的细长主体、吸入管道及用于使脏物和灰尘与空气流分离的灰尘袋。在主体中与电源一起设有马达和风扇组件。手柄位于手持式真空吸尘器的上部。手柄平行于细长主体、与吸入管道呈小角度地延伸，气流发生器和电源两者处于主体内手柄的下方。JP2004-041760公开了具有类似手柄配置的手持式真空吸尘器。然而，在此情况中，将手持式真空吸尘器的马达和风扇组件及电源安置成使得器械的重心位于手柄的中心处。 
US 1,871,624示出了另一种手柄配置。该文件披露的真空吸尘器具有圆柱形主体和安置在一端的手柄。弯曲的吸入管道位于与手柄相对的一端。手柄被安置成横过圆柱形主体的纵向轴线，并大致平行于吸入管道。与GB1 207 278和JP 2004-041760中公开的手柄配置相比，这种配置在使用时可向使用者提供施加大力的手腕位置。但是，这种真空吸尘器在使用状态时，真空吸尘器的沉重部件(例如，马达和风扇组件)相对于使用者的手而言处于手柄的前方。因此，相应的手持式真空吸尘器的质量中心将位于手柄的前方。结果，因为使用者不得不付出附加的努力将手持式真空吸尘器保持在固定方位，使用上面描述的这种手持式真空吸尘器既劳累又令人感到不舒服。 
发明内容
本发明的目的是提供一种手持式真空吸尘器，其在使用时比公知的配置更便于操纵。本发明的另一目的是提供一种手持式真空吸尘器，其中，手柄、马达和风扇组件及电源的配置可使得手持式真空吸尘器的操纵既方便又惬意。 
本发明所提供的手持式清洁设备包括具有纵向轴线的吸入管道、用于产生沿吸入管道流动的气流的气流发生器、分离装置、用于向气流发生器供电的电源和细长把手，分离装置被安置成与吸入管道相通，以使脏物和灰尘与气流分离，把手设置在气流发生器和电源之间，把手的尺寸和位置被安置成适于由使用者的手抓握，其中，所述细长把手以接近直角的角度横向于(transverse to)吸入管道的纵向轴线。借助带有这种配置的手持式清洁设备，使用者可保持舒适的手腕状态，而且手持式真空吸尘器的动作也使人感到舒服。 
优选细长把手与纵向轴线所成角度在80°至90°范围内。 
优选使分离装置位于吸入管道和细长把手之间。这种配置可改善手持式真空吸尘器的重量平衡。 
优选吸入管道具有吸入开口，纵向轴线通过该吸入开口。这种配置使得使用者觉得自然并便于使用。 
附图说明
现在将参考附图对本发明一实施例进行描述。附图中： 
图1为本发明的手持式真空吸尘器的立体图； 
图2为图1所示的手持式真空吸尘器的局部剖切侧视图； 
图3是图1所示的手持式真空吸尘器的平面图。 
具体实施方式
图1示出了一种手持式真空吸尘器10。手持式真空吸尘器10包括主体12。主体12包括具有吸入开口16的吸入管道14。主体12还包括旋风分离装置18，以使脏物和灰尘从吸进吸入开口16的气流分离。旋风分离装置18与吸入管道14和吸入开口16连通。旋风分离装置18包括上游旋风器20和多个下游旋风器22，对本发明而言，旋风器的细节不是实质性的，因此，在此不作描述。 
主体12还包括马达壳体24，该壳体具有多条形成于其内的排气道26。气流路径从吸入开口16经吸入管道14、旋风分离装置18和马达壳体24延伸到排气道26。手柄28位于马达壳体24的下方，以便使用时操纵手持式真空吸尘器10。可将手柄28安置成使得旋风分离装置18位于手柄28和吸入开口16之间。手柄28包括触发开关(trigger switch)30，可将该开关定位于手柄28的离吸入开口16最近的那侧上，因此，使用者可用食指操作触发开关30。电源32可通过安装部分34与手柄28连接。 
图2示出了手持式真空吸尘器10的更多细节。气流发生器36位于马达壳体24内。在本实施例中，气流发生器36采用马达和风扇组件的形式。气流发生器36具有入口38和出口40。马达前过滤器42位于入口38的上游，用于从气流中过滤出细小颗粒。马达后过滤器44位于出口40的下游。马达前过滤器42和马达后过滤器44都位于气流路径内。 
手柄28采用细长把手的形式，手柄具有第一端46、第二端48和轴线X-X。手柄28的第一端46连接到马达壳体24。气流发生器36邻近手柄28的第一端46。在本实施例中，将手柄28和气流发生器36安置成使得手柄28的轴线X-X通过气流发生器36的至少一部分。 
安装部分34可拆卸地接收电源32。将电源32装配到手持式真空吸尘器10上时，该电源与手柄28的第二端48直接相邻。在本实施例中，将电源32和手柄28安置成使得轴线X-X穿过电源32的至少一部分。 
换句话说，将手柄28安置在气流发生器36和电源32之间。在本实施例中，轴线X-X通过气流发生器36和电源32各自的至少一部分。此外，手柄28的轴线X-X横过吸入管道14的纵向轴线Y-Y。纵向轴线Y-Y穿过吸入开口16。在本实施例中，将轴线X-X设置成与纵向轴线Y-Y成一角度，该角度接近90°。这种配置使得使用者感觉很舒适。 
触发开关30朝向手柄28的第一端46。触发开关30位于电源32和气流发生器36之间，该开关能切换气流发生器36使之接通或断开。触发开关具有接通和切断位置。如从图2所看到的那样，触发开关可从左移动到右。切断位置处于左侧，接通位置处于右侧。在切断位置，触发开关30处于断开(open)状态，气流发生器36被切断。在接通位置，触发开关30闭合(close)，气流发生器36被切换为接通。触发开关30包括弹簧50，该弹簧将触发开关30偏压为常开状态(normally open state)。这种配置使得使用者可用食指方便地操作触发开关30。进而用一只手就可操作手持式真空吸尘器10。 
使用时，使用者抓握手柄28以操纵处于使用状态的手持式真空吸尘器10。使用者按压触发开关30时，气流发生器36运转。为使气流发生器36保持运转，使用者必需维持施加于触发开关30上的压力。这意味着，使用者不需要进行清洁工作时，如将吸尘器从一房间搬到另一房间时，他或她可释放触发开关30。若使用者释放触发开关30，弹簧50将触发开关30偏压到切断位置，气流发生器36停止运转。这可减少出现不需要时还使用气流发生器36的情况，从而可节省电池的工作时间和马达的运行时间。 
操作时，气流发生器36将夹带有脏物和灰尘的空气吸进吸入开口16、流过吸入管道14而进入旋风分离装置18。夹带有脏物和灰尘的空气进入上游旋风器20，借助气旋运动使较大的脏物和灰尘颗粒分离。然后，将这些颗粒收集在上游旋风器20中。 
然后使经部分清洁的气流进入多个下游旋风器22。与上游旋风器20相比，下游旋风器22可从部分清洁的气流中分离出更小的脏物和灰尘颗粒。被清洁的空气在通过排气道26从手持式真空吸尘器10排出之前流出旋风分离装置16、接着依次流过马达前过滤器42、气流发生器36和马达后过滤器44。 
使用中，使用者可能要清洁不同角度取向的各种表面。所以，为了高效地清洁，使用者需要提起手持式真空吸尘器10并将其移动到不同位置和不同方位。处于气流发生器36和电源32之间的手柄28的位置使得手持式真空吸尘器10在使用中更便于操纵。这是因为使用者可将手放在手持式真空吸尘器10的两个最重的部件之间的缘故。这导致“哑铃状”的结构，在该结构中手持式真空吸尘器10的重量分布在使用者的手的两侧上。 
吸入管道14的纵向轴线Y-Y相对于手柄28的轴线X-X的横向配置导致使用者的手腕基本伸直时吸入管道14形成使用者的前臂的基本笔直的延伸。这种配置使得使用者尤其在使用手持式真空吸尘器10一段时间后感到很舒服。此外，吸入管道14的纵向轴线Y-Y的位置紧邻手持式真空吸尘器10的中心，这意味着吸入管道14的纵向轴线Y-Y与使用者前臂转动的纵向轴线一致，或者紧邻使用者前臂转动的纵向轴线。结果，使手持式真空吸尘器10转动时，吸入开口16的轴向位移很小或者没有。 
本发明不限于上述具体实施例的这些特征。显然，本领域技术人员可以作出很多改型。例如，可以变换气流发生器或电源的具体位置。气流发 生器可直接邻近手柄的第一端。气流发生器可处于手柄的上方或下方。再者，电源可直接邻近手柄的第二端。电源可处于手柄的上方或下方。重要的是，气流发生器邻近手柄的第一端，电源邻近手柄的第二端。 
可改变吸入管道的纵向轴线和手柄的轴线之间的角度关系。优选吸入管道的纵向轴线和手柄的轴线之间的所成角度在80至90°的范围。当然重要的是，这些轴线应互为横向，使得使用者操纵手持式真空吸尘器时感到舒适。 
不是必须使用旋风分离单元。也可使用如袋式过滤器之类的其它分离装置。此外，手持式真空吸尘器不必装备可充电电源。可采用标准电池或电源线。再者，本发明不限于手持式真空吸尘器。可采用其他类型的手持式清洁设备，例如，地毯清洁器、湿式和干式机(wet and dry machines)、或鼓风真空设备(blower vacuum devices)。
