优选地，本实施例中，吸尘器100还包括夹设于分离集尘组件30和抽吸组件40之间的过滤组件50，过滤组件50位于从出风口3130至抽吸口401的气路通道路上，过滤组件50包括海绵、静电棉等的至少其中之一。通过出风口3130离开分离集尘组件30的气流，通过过滤组件50再次过滤后形成更为洁净的气流，流向抽吸口401。
本发明中提供的分离集尘组件30，能够相较于现有技术至少降低空气动能损耗。下面参图1至图5，介绍该实施例的分离集尘组件30的具体结构。
首先，参看图1和图2，本实施例中的分离集尘组件30的尘杯31和尘气分离器32同轴设置，二者均具有中心轴V，在后文中以中心轴V为参照定义“轴向”、“径向”、“圆周方向”等概念。当然，在变化实施例中尘杯31和尘气分离器32可以非同轴设置，则相应的“轴向”、“径向”、“圆周方向”等概念应当以各自的中心轴为参照予以理解。另外，本实施例中，中心轴V竖直延伸，也即分离集尘组件30竖直设置，当然不限于此，中心轴V还可以倾斜延伸。
下面介绍尘杯31的具体结构，尘杯31包括盖板311、侧壁312和基板313。
侧壁312呈绕中心轴V设置的筒形(也即中心轴V也是侧壁312的中心轴)，其具体可如本实施例设置为等径筒(即圆柱筒)、非等径筒(例如圆锥台、直径突变的台阶式圆柱筒)、矩形筒或其它。
盖板311设于侧壁312的轴向一端，具体为设于侧壁312的上端，当吸尘器100执行清洁作业时，盖板311可以通过卡扣、螺纹、铰链等任一种或任意组合的方式密封扣合至侧壁312；当吸尘器100完成清洁作业后，盖板311还可至少部分地脱开侧壁312，以使尘杯31的内腔被暴露在外，从而便于操作者对尘杯31内腔中的尘杂进行清理，或者对尘气分离器3进行维修更换。
基板313与盖板311沿轴向相对设置，其设于侧壁312的轴向另一端，具体为设于侧壁312的下端。在本实施例中，基板313可拆卸地密封扣合在侧壁312的下端。
如前文所述，尘杯31具有进风口3120和出风口3130，在本实施例中，进风口3120设在侧壁312的上部，出风口3130设在基板313的中心位置处，盖板311呈封闭状。当盖板311和基板313均密封扣合至侧壁312时，盖板311封闭侧壁312的上端，尘杯31的内腔仅可以通过进风口3120和出风口3130连通至尘杯31的外部。在变化实施例中，进风口3120和出风口3130的位置不限于此，例如，出风口3130还可以设在盖板311上。
优选地，进风口3120由外向内(也即顺着气流的流动方向)沿尘杯31侧壁312的切线方向延伸，换句话说，进风口3120的延伸方向T为尘杯31侧壁312的切线。这样，延伸方向T垂直于中心轴V并且为圆柱形侧壁312的切线，使得气流能够由外向内切向进入尘杯31的内腔中，并沿着侧壁312的内壁面流动，能够使得气流规律化流动，降低气流紊乱现象。
接下来，参看图2至图5，介绍尘气分离器32的具体结构，尘气分离器32整体上布设于尘杯31内腔的中心位置处，其与尘杯31同轴设置。尘气分离器32具体包括主体机构321、导风罩322、分流板323、裙部324和过滤件325。
主体机构321包括装配部3213、分离筒3211和出风筒3212。从位置布局上来讲，装配部3212连接于分离筒3211的轴向第一端，出风筒3212连接于分离筒3211的轴向第二端，分离筒3211位于装配部3212和出风筒3212之间，在本实施例中，也即装配部3212连接于分离筒3211上端，出风筒3212连接于分离筒3211下端。
进一步地，装配部3212和分离筒3211一体设置，二者通过装配部3212固定装配至尘杯31上，具体来讲，装配部3212大致呈自分离筒3211上端远离中心轴V向外延展的环形，装配部3212的四周外缘32132被紧密地夹持于侧壁312和盖板311之间。
出风筒3212位于分离筒3211和基板313之间，其上端套设于分离筒3211 下端外部，其下端配接在基板313上的出风口3130四周，当然，若在变化实施例中出风口3130的位置发生变化，出风筒3212的造型可适应性调整变化，另外，出风筒3212与分离筒3211还可以由本实施例的组装关系变化为一体设置。
主体机构321将尘杯31的内腔分割为第一腔室和第二腔室。其中，所述第一腔室为形成于主体机构321和侧壁312之间的集尘腔301，也即形成于主体机构321外部，尘杯31的进风口3120交汇连通于集尘腔301。所述第二腔室形成于主体机构321内部，所述第二腔室的下部为由出风筒3212的内壁面围出的出风腔3022，尘杯31的出风口3130交汇连通于出风腔3022，所述第二腔室的上部大致由分离筒3211与盖板311合围出。
分离筒3211具有若干分离口3210，分离口3210的数目具体可设置为一个、两个或更多个，分离口3210可设置为任意的形状，全部分离口3210的具体形状设置为全部相同、全部不同或者部分相同。每个分离口3210贯通分离筒3211的内壁面和外壁面，所述第二腔室的上部(分离筒3211内部)与集尘腔301(分离筒3211外部)通过分离口3210相连通，这样，通过进风口3120进入尘杯31内腔的气流，由集尘腔301通过分离口3210进入所述第二腔室的上部，之后气流在所述第二腔室内由上而下通过出风腔3022流向出风口3130。
优选地，分离筒3211的外周包覆设置过滤件325，过滤件325具体可设置为滤网，该滤网的材质、网孔大小、网孔密度等参数视吸尘器100的具体需求而定。这样，在含尘气流通过分离口3210由集尘腔301进入所述第二腔室的上部时，过滤件325阻拦含尘气流中的尘杂以使尘杂留存在集尘腔301内，而被过滤后的气流穿过过滤件325进入所述第二腔室的上部。其中，过滤件325的设置位置、设置方式、具体结构等不限于此。
进一步地，导风罩322将所述第二腔室的上部分隔为相互密封隔绝的两部分。导风罩322的上端密封连接于装配部3213且由上而下延伸至分离筒321内，具体地，导风罩322的上端的外边缘设置向下延伸的翻边3221，主体机构321的装配部3213包括凸缘32131和位于凸缘32131外周的凹槽32130，导风罩322的翻边3221越过凸缘32131挂扣在凹槽32130内，且翻边3221紧密贴合凸缘 32131，以使得导风罩322密封地悬挂配接在主体机构321上。
以导风罩322为界，所述第二腔室的上部被分隔为封闭腔3021和导风腔，其中，所述导风腔形成于导风罩322和分离筒3211之间，所述导风腔的下端连通出风腔3022，气流通过分离口3210进入所述导风腔，之后通过所述导风腔流向出风腔3022；封闭腔3021形成在导风罩322和盖板311之间，封闭腔3021与所述导风腔被导风罩322密封隔绝，二者完全分隔且彼此不相连通。这样，通过在分离筒3211内设置导风罩322，一方面可通过导风罩322引导气流的流向，另一方面，利用导风罩322将所述导风腔与封闭腔3021隔绝开来，相较于现有技术中贯通式的设置(相当于封闭腔3021与所述导风腔连通)，可以避免封闭腔3021处形成负压而产生涡流，降低空气动能损耗。当然，在变化实施例中，导风罩322可以与分离筒3211以及/或者与装配部3213一体设置。
进一步地，分离筒3211包括形成于部分分离口3210与装配部3213之间的挡风部32111，挡风部32111与进风口3120位置相对应，以使得自进风口3120进入集尘腔301内的含尘气流与分离筒3211首先接触于挡风部32111处，并在挡风部32111的阻挡下形成环绕分离筒3211向下螺旋式的气流(参图2中粗箭头示意)，以形成旋风式分离机制；相对应的，导风罩332包括设于其外壁面的密封凸部3222，该密封凸部3222填充挡风部32111的内部空间以紧密贴合挡风部32111的内壁面。这样，通过密封凸部3222将挡风部32111的内部空间加以填充，可进一步减少主体机构321内部的闲置空间，避免挡风部32111的内部空间处形成负压而造成涡流，进而提升降低空气动能损耗的效果。当然，不限于此，在变化实施例中，密封凸部3222还可以设置为围绕挡风部32111设置的板状结构，具体其位于挡风部32111和分离口3210之间以使挡风部32111的内部空间与所述导风腔密封隔绝，这样同样可达到避免挡风部32111的内部空间处形成负压而造成涡流的效果。
进一步地，导风罩322大致呈倒置的圆锥形，其上端连接主体机构321，其下端逐渐趋近主体机构321的中心轴V。导风罩322具有位于分离口3210内侧的导向壁面3220，该导向壁面3220构成导风罩322外壁面的一部分，在由上至 下的轴向上，导向壁面3220呈内凹弧形并逐渐趋近中心轴V。一方面，让气流可以顺利通过分离口3210进入所述导风腔内，另一方面，使气流沿着导向壁面3220向出风腔3022流动，提升导风效果，减少气流在导向壁面3220处的紊乱，降低空气动能损耗。当然，导向壁面3220可以设置为连续面或突变的不连续面。
分流板323的数目设置为至少两个，在附图示例中，分流板323设置为六个。分流板323布设于所述导风腔内，并且六个分流板323沿圆周方向绕中心轴V依次排布，六个分流板323将所述导风腔分隔为沿圆周方向分布的六个子风腔，当然，分流板323的数目和所述子风腔的数目相对应且不限于此。这样，通过在导风罩323和分离筒3211之间设置至少两个分流板323，以便于将导风罩323和分离筒3211之间的所述导风腔分隔为至少两个所述子风腔，这样，不仅利于气流沿不同所述子风腔流动，减少气流在所述导风腔内的紊乱，降低空气动能损耗，而且还可以搅动分离筒3211外部的气流，降低切向气流速度，从而防止集尘腔301中已经沉降的尘杂被二次扬起。
进一步地，任意相邻的两个所述子风腔被二者之间的分流板323完全隔离而不相连通，每个所述子风腔的下端具有形成在相邻两个分流板323之间的开口，这样，不同所述子风腔彼此独立，进入不同的所述子风腔内的气流直接通过所述开口流向出风腔3022，而不会发生气流串通，从而进一步减少气流在所述导风腔内的紊乱，降低空气动能损耗。
分流板323沿径向延伸，且其内端接触连接导风罩322的外壁面，其外端接触连接分离筒3211的内壁面。在本实施例中，分流板323一体设置于分离筒3211，分流板323自分离筒3211内壁面沿径向向内延伸直至与导风罩322的外壁面紧密贴合接触，这样，一方面可以通过分流板323将其两侧的两个所述子风腔隔离开来，避免气流在相邻两个所述子风腔内串流，另一方面，分流板322径向延伸以减小所述子风腔内气流的切向流动，从而降低空气动能损耗。当然，在变化实施例中，分流板323可以一体设于导风罩322，其自导风罩322的外壁面沿径向向外延伸直至与分离筒3211内壁面紧密贴合接触；或者，分流板323可以一体设于导风罩322和分离筒3211；再或者，分流板323可以与导风罩322 和分离筒3211分体设置。
进一步地，分流板323平行于中心轴V，总得来讲，每个分流板323布设于尘杯31的径向面上。这样，可进一步引导气流沿所述子风腔向下流动。
本实施例中，分流板323位于相邻两个分离口3210之间，并且将位于其两侧的两个分离口3210隔离开来。具体地，分流板323的上端不低于位于其两侧的两个分离口3210的至少其一，分流板323的下端低于分离口3210(即分流板323的下端相对分离口3210更为靠下)，这样，可以使通过分离口3210的任意高度处进入所述导风腔内的气流都可以及时接触分流板323而改变气流方向，进一步减小所述子风腔内气流的切向流动，从而降低空气动能损耗。
进一步地，裙部324连接主体机构321，并且自主体机构321向外趋近侧壁312延伸以及向下趋近基板313延伸；裙部324位于分离口3210的下方，在本实施例中，裙部324一体设置在分离筒3211的下端部处，其大致上介于分离筒3211和出风筒3212之间。通过设置裙部324，一方面，在集尘腔301内，被过滤件325从含尘气流中阻拦分离出的尘杂，在裙部324的引导下，向下沉降至集尘腔301的底部(也即积存在尘杯31的基板313上方)，另一方面，沉降在集尘腔301底部的尘杂，在裙部324的阻挡作用下，大大降低了被气流二次扬起至分离口3210处的几率，避免尘杂积堵分离口3210，保证清洁效果，降低空气动能损耗。
以上对本实施例的分离集尘组件30的结构进行了说明，进一步地，在本实施例中，抽吸组件40组装于分离集尘组件30的下方，抽吸装置41的抽吸口401与分离集尘组件30的出风口3130同轴正对设置，优选地，抽吸装置41与尘杯31同轴设置，如此，从出风口3130至抽吸口401的气路通道路径短，降低过长气路通道造成的空气动能损耗，从而可以提升吸尘器100的整体性能。
综上所述，与现有技术相比，本实施例的吸尘器100的有益效果在于：
(1)通过在分离筒3211内设置导风罩322，一方面可通过导风罩322引导气流的流向，另一方面，利用导风罩322将所述导风腔与封闭腔3021隔绝开来，相较于现有技术中贯通式的设置(相当于封闭腔3021与所述导风腔连通)，可 以避免封闭腔3021处形成负压而产生涡流，降低空气动能损耗；
(2)通过密封凸部3222，可进一步减少主体机构321内部的闲置空间，避免挡风部32111的内部空间处形成负压而造成涡流，进而提升降低空气动能损耗的效果；
(3)通过优化导风罩322的导向壁面3220的形状，一方面，让气流可以顺利通过分离口3210进入所述导风腔内，另一方面，使气流沿着导向壁面3220向出风腔3022流动，提升导风效果，减少气流在导向壁面3220处的紊乱，降低空气动能损耗；
(4)通过设置分流板323，将所述导风腔分隔为至少两个所述子风腔，不仅利于气流沿不同所述子风腔流动，减少气流在所述导风腔内的紊乱，降低空气动能损耗，而且还可以搅动分离筒3211外部的气流，降低切向气流速度，从而防止集尘腔301中已经沉降的尘杂被二次扬起。
实施例2
参图6至图8，示出了本发明另一优选实施例，与实施例1中相同或相似特征的构件，本实施例中采用与实施例1中相同的标号结合字母“a”进行标示。
本实施例与实施例1的区别点主要在于：裙部与主体机构的连接方式。下面仅针对该区别点进行详细描述，其他与实施例1相同的部分，在此不再赘述。
参图6至图8，不同于实施例1的裙部324与分离筒3211一体设置，本实施例中裙部324a与分离筒3211a分体设置，裙部324a组装套设在主体机构321a外部。
具体地，裙部324a的顶端中部具有通道3241a；主体机构321a设置有第一组装部3215a和第二组装部3216a，在尘气分离器32a的中心轴Va所界定的轴向上，第一组装部3215a和第二组装部3216a均位于分离口3210a的下方，且第一组装部3215a位于第二组装部3216a的上方，裙部324a可选择性地组装固定于第一组装部3215a和第二组装部3216a的其中之一并且还可以非破坏性地拆卸下来，以在第一组装部3215a和第二组装部3216a二者上进行变换。也即，裙部324a可供操作者按照需求组装固定于第一组装部3215a，此时可以增大集尘腔 301在裙部324a下方的体积，增大储存灰量，适用于吸尘器100对重量相对较大、体积较小的尘杂的清洁，例如灰尘、石英砂、木屑、大米、甜甜圈等尘杂，容易沉降到尘杯31集尘腔301的底部；裙部324a也可供操作者按照需求固定组装于第二组装部3216a，此时适用于吸尘器100对主要为毛发、纸屑、织物等的尘杂进行清洁，这些尘杂不易沉降到尘杯31集尘腔301的底部，通过增大裙部324a和分离口3210a之间的距离，可以防止毛发、纸屑、棉絮等积堵在分离口3210a处，从而减小空气动能损耗。
优选地，第一组装部3215a和第二组装部3216a均设于出风筒3212a外壁面处。具体地，出风筒3212a包括上端筒体32121a和下端筒体32122a，第一组装部3215a设置在上端筒体32121a外壁面上，在进行裙部324a的组装时，裙部324a可从上端向下套设在上端筒体32121a外部并固定组装于第一组装部3215a，之后上端筒体32121a的上端与分离筒3211a的下端相套接即可；第二组装部3216a设置在下端筒体32122a外壁面上，在进行裙部324a的组装时，裙部324a可从上端向下套设在下端筒体32122a外部并固定组装于第二组装部3216a，之后下端筒体32122a的上端与上端筒体32121a的下端相套接即可。当然在变化实施例中，上端筒体32121a和下端筒体32122a可一体设置，出风筒3212a和分离筒3211a可一体设置，第一组装部3215a和第二组装部3216a的设置位置、裙部324a与主体机构321的组装方式不限于此，只需要裙部324a能够可调节地在分离口3210a下方不同高度的两个位置之间选择性组装，均可以达到防止尘杂积堵处分离口3210a的效果。
综上所述，与现有技术相比，本实施例的吸尘器除了具备与实施例1相同的有益效果之外，还进一步具有如下有益效果：通过设置第一组装部3215a和第二组装部3216a，以供操作者根据尘杂类型调节裙部324a与主体机构321a的组装位置，使得适应于重量相对较大、体积较小的尘杂而将裙部324a组装在第一组装部3215a处，以增大储存灰量，也可以适应于重量相对较小、体积较大的尘杂(如毛发、纸屑、棉絮等)而将裙部324a从第一组装部3215a移至下方的第二组装部3216a，通过增大裙部324a和分离口3210a之间的距离，防止尘 杂积堵在分离口3210a处，从而减小空气动能损耗。
实施例3
参图9，示出了本发明另一优选实施例，与实施例1中相同或相似特征的构件，本实施例中采用与实施例1中相同的标号结合字母“b”进行标示。
本实施例与实施例1的区别点主要在于：尘杯的进风口的延伸方向。下面仅针对该区别点进行详细描述，其他与实施例1相同的部分，在此不再赘述。
参图9，不同于实施例1的进风口3120的延伸方向T为尘杯31侧壁312的切线，本实施例中，进风口3120b的延伸方向Tb不为尘杯31b侧壁312b的切线。具体地，本实施例中，侧壁312b呈绕中心轴Vb设置的筒形，其进风口3120b由外向内(也即顺着气流的流动方向)的延伸方向Tb，位于侧壁312b的一切向面上，该切向面穿过切线H(该切线H可近似等同于实施例1中的延伸方向T)且平行于中心轴Vb；并且，延伸方向Tb与切线H呈锐角夹角地向下倾斜。也即进风口3120b由外向内斜向下延伸。
这样，与现有技术相比，本实施例的吸尘器除了具备与实施例1相同的有益效果之外，还进一步具有如下有益效果：将进风口3120b由外向内斜向下延伸，可以使气流通过进风口3120b时向下倾斜流动，增大尘杯31b内部气流轴向向下的速度，将毛发、棉絮等轻质尘杂的空间体积压缩，并将尘杂压向裙部，降低尘杂附着积堵在分离口处的几率，进而降低空气动能损耗。
应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施方式中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
