一方面，如图1所示，本申请一实施例提供了一种吸尘器的出风导向件，该出风导向件2设置于吸尘器的外壳1内(参见2至图4)；出风导向件2具有用于容纳气流发生器3的容纳腔和分别与容纳腔连通的入风口2a、至少一个排风风道2b。其中，如图2及图3所示，入风口2a与吸尘器的分离组件4的排气口41a连通，且入风口2a还与气流发生器3的吸气口3a相贴合；排风风道2b由气流发生器3至外壳1的方向延伸并对准外壳1的出风口1a、气流发生器3的排气口3b。
上述所述的吸尘器的出风导风件，出风导向件2的排风风道2b连通于气流发生器3的排气口3b与外壳1的出风口1a之间，使得气流发生器3排放的气体经出风导向件2的排风风道2b，便可直接从外壳1的出风口1a排出，与目前的气流发生器3排放的气体从集尘杯5的底部排出相比，本申请的出风导风件可保证集尘杯5不被气流发生器3排放的气体吹掉。
如图2及图3所示，在本申请的一些实施例中，排风风道2b的设置数目为多个，多个排风风道2b沿周向均匀间隔分布；每相邻两个排风风道2b之间的间隙用于使分离组件4中对应的分离器41的排尘口41b伸入至吸尘器的集尘杯5内，其中集尘杯5与外壳1对接。可以理解的是，分离组件4安装于外壳1的内腔中。如上所述的吸尘器，出风导向件2的多个排风风道2b沿周向分布，且每个排风风道2b连通于气流发生器3的排气口3b与外壳1的出风口1a之间，使得气流发生器3排放的气体经出风导向件2的排风风道2b，即横跨分离器41，便可直接从外壳1的出风口1a排出，与目前的气流发生器3排放的气体从集尘杯5的底部排出相比，本申请的吸尘器不仅排风风道2b长度大大变短，利于气体的排出，可保证吸尘器具备更大的吸力；另外，也可保证吸尘器的内部结构紧凑化。
进一步地，在本申请的一些实施例中，如图1所示，出风导向件2包括：具有入风口2a的内壳体21、套设在内壳体21外部的外壳体22以及沿周向间隔分布的多个通风体23；每个通风体23均连通于内壳体21与外壳体22之间，且每个通风体23的内腔构成一个排风风道2b；气流发生器3设置于内壳体21内。
可选地，内壳体21和外壳体22可分别设置成圆筒结构。
具体到本申请的一些实施例中，如图2所示，每个分离器41的排尘端外廓呈锥形结构，锥形结构的直径由外壳1至集尘杯5的方向逐渐减小；每个通风体23的内腔沿周向的长度由外壳1至集尘杯5的方向逐渐减小。如此，可依据分离器41的形状来设定通风 体23的内腔形状，使得出风导向件2的排风风道2b宽度最大，利于气流发生器3排放的气体可无阻力地排出至吸尘器的外部。需要说明是，分离器41的排尘端指的是分离器41中靠近集尘杯5的一端。
具体地，如图2所示，分离组件4中的每个分离器41均包括分离主体411和盖体412，分离主体411上开设有排气口41a、排尘口41b和进口41c，盖体412上开设有与排气口41a连通的第一开口、与进口41c连通的第二开口和与分离主体411内腔连通的第三开口；每个分离器41的分离主体411通过第一固定环414集成在一起，每个分离器的盖体412通过第二固定环415集成在一起。其中，如图2及图3所示，第二固定环415与每个分离主体411的排气口41a、进口41c之间具有第三密封件63(例如密封橡胶圈)。
具体到本申请的一些实施例中，如图1所示，每个通风体23的一端口与内壳体21之间的连接处平滑过渡，每个通风体23的另一端口与外壳体22之间的连接处平滑过渡。如此，可以减小排风风道2b对流经气体的阻力，进而可提高气流发生器3的吸力强度。其中，每个通风体23的一端口与内壳体21一体化成型，且这两者之间的连接处设置成弧形结构；每个通风体23的另一端口与外壳体22一体化成型，且这两者之间的连接处设置成弧形结构。
可选地，每个通风体23沿内壳体21的径向延伸，以使每个排风风道2b的长度更短。
可选地，通风体23的设置数量为10个～14个，举例来说，可以设置12个。需要说明的是，相邻两个通风体23之间的间隙可以使一个分离器41的排尘口41b穿过，也可以使相邻的多个(例如两个、三个、四个等)分离器41的排尘口41b穿过。
可选地，如图2及图3所示，每个分离器41的排尘端外廓呈锥形结构，该锥形结构的直径由外壳1至集尘杯5的方向逐渐减小；如图1所示，内壳体21中远离集尘杯5的一端凸出外壳体22，且内壳体21中远离集尘杯5的一端的外径由外壳1至集尘杯5的方向逐渐减小。如此，可使吸尘器的内部结构更紧凑化。
进一步地，如图2及图3所示，在本申请的一些实施例中，外壳体22中远离集尘杯5的第一边沿221与外壳1之间设置有第一密封件61；外壳体22中靠近集尘杯5的第二边沿222与集尘杯5之间设置有第二密封件62。如此，第一密封件61可以阻挡外界空气经外壳1的出风口1a流入至外壳1中，第二密封件62可以阻挡外界空气经外壳1的出风口1a流入至集尘杯5中。
具体到本申请的一些实施例中，如图3所示，第一密封件61包括：相连接的安装壁61a和密封壁61b，安装壁61a与密封壁61b之间的间距由外壳1至集尘杯5的方向逐渐增大；安装壁61a沿竖直方向设置在第一边沿221上，密封壁61b用于密封外壳体22与外壳 1之间的缝隙。如此，当气体从排风风道2b流出时，可以向第一密封件61的密封壁61b施加压力，使第一密封件61的密封壁61b充分变形，进而可以密封地贴合在外壳1的内壁上，可有效密封外壳体22与外壳1之间的缝隙。
可选地，第一密封件61可以为横截面为倒V形的密封橡胶圈。
可选地，第一边沿221上具有安装槽，第一密封件61的安装壁61a置于安装槽中。如此，便于第一密封件61的更换。
可选地，第二密封件62可以为环状的密封橡胶圈。
具体到本申请的一些实施例中，第二边沿222中面向集尘杯5的壁上由内至外依次间隔设置有至少一个环状凸起；每个环状凸起均与第二密封件62挤压相抵。如此，外壳体22的第二边沿222可利用环状凸起有效挤压第二密封件62，以提高第二密封件62的密封性能。
另一方面，如图2及图3所示，本申请还提供一种吸尘器，该吸尘器包括：外壳1、气流发生器3、分离组件4、集尘杯5和上述任一项所述的出风导向件2；出风导向件2设置于外壳1内；气流发生器3设置于出风导向件2内；集尘杯5与壳体1对接；分离组件4设置于外壳1内或集尘杯5中。
上述所述的吸尘器，出风导向件的排风风道连通于气流发生器的排气口与外壳的出风口之间，使得气流发生器排放的气体经出风导向件的排风风道，便可直接从外壳的出风口排出，与目前的气流发生器排放的气体从集尘杯的底部排出相比，本申请的吸尘器可保证集尘杯不被气流发生器3排放的气体吹掉。
在本申请的一些实施例中，如图2至图3所示，吸尘器还包括：设置于外壳1与出风导向件2之间的阻挡件7；阻挡件7上设置有与出风口1a、出风导向件2的排风风道2b连通的通气孔7a。如此，可以避免外界杂质(例如螺钉)由外壳1的出风口1a并经排风风道2b中落入至气流发生器3中，进而可以避免气流发生器3发生损坏。
可选地，阻挡件7可以为环状的过滤棉，阻挡件7可以置于外壳体22与外壳1的内壁之间所配合构成的夹持腔中。
如图2及图3所示，在本申请的一些实施例中，排风风道2b的设置数目为多个，多个排风风道2b沿周向均匀间隔分布；分离组件设置于4外壳1内，且分离组件4的多个分离器41围绕气流发生器3分布；其中每个分离器41的排尘口41b穿过对应的相邻两个排风风道2b之间的间隙伸入至集尘杯5中。如上所述的吸尘器，出风导向件2的多个排风风道2b沿周向分布，且每个排风风道2b连通于气流发生器3的排气口3b与外壳1的出风口1a之间，使得气流发生器3排放的气体经出风导向件2的排风风道2b，即横跨分 离器41，便可直接从外壳1的出风口1a排出，与目前的气流发生器3排放的气体从集尘杯5的底部排出相比，本申请的吸尘器不仅排风风道2b长度大大变短，利于气体的排出，可保证吸尘器具备更大的吸力；另外，也可保证吸尘器的内部结构紧凑化。
如图2所示，在本申请的一些实施例中，集尘杯5上具有进风口5a，且进风口5a与每个分离器41的吸气口41c之间形成有气体通道(参见图4)；吸尘器还包括：位于集尘杯5内的集尘部8，集尘部8的进口与每个分离器41的排尘口41b连通，集尘部8的出口贴合在集尘杯5的底壁上。需要说明的是，集尘杯5的顶部开口与集尘部8的进口之间具有间隙，且该间隙与出风导向件2中的相邻两个排风风道2b之间的间隙相连通，以使集尘杯5的进风口5a与分离器41的进气口41c之间形成气体通道。
应用时，如图4所示，外界含尘空气先经集尘杯5的进风口5a进入至集尘杯5中，然后经进风口5a与分离器41的吸气口41c之间所形成的气体通道流入至分离组件4中。外界含尘空气通过分离组件4分离之后，外界含尘空气中的灰尘由分离器41的排尘口41b排入至集尘杯5中，与其同时，分离后的空气由分离器41的排气口41a进入至气流发生器3中，之后，依次经气流发生器3的排气口3b、出风导向件2的排风风道2b直接排放至外壳1的外部。需要说明的是，图4中的箭头表示气体流动方向。
可选地，集尘部8设置成漏斗结构。
可选地，集尘部8的出口处可安装有第四密封件64(参见图3)，以使集尘部8的出口密封地贴合在集尘杯5的底部上。其中，第四密封件64可以为具有开口的盒状结构，且材质可以为橡胶。

更进一步地，在本申请的一些实施例中，如图2所示，至少一个分离器41的外壁上设置有至少一个第一螺柱413；旋风筒9的排风口处设置有至少一个第二螺柱91；每个第二螺柱91通过紧固件与对应的第一螺柱413连接。如此，不仅可以实现分离组件4与旋风筒9的连接，也可以将集尘部8的进口夹持在分离组件4与旋风筒9之间。
需要说明的是，第一螺柱413中远离集尘杯5的一端与对应的分离器41外壁连接，第一螺柱413中靠近集尘杯5的一端与对应的分离器41外壁之间具有宽度大于集尘部4进口壁厚的间隙，以使第一螺柱413中靠近集尘杯5的一端可与对应的第二螺柱91连接。

可以理解的是，第一弧形段81的设置个数与分离组件4的每个分离器41的设置个数相同，例如均设置12个。
进一步地，如图2及图3所示，在本申请的一些实施例中，吸尘器还包括：固定在集尘部8的进口处的底座10，底座10用于将气流发生器3支撑在外壳1内。

可选地，支撑杆101为螺柱。对应地，第一减震环111的外壁上也设置有多个螺柱。其中，支撑杆101可沿底座10的周向可设置6个～8个，举例来说可以为6个。
