具体实施方式
下面结合附图对本发明做进一步的详细说明，本发明的前述和其它目的、特征、方面和优点将变得更加明显，以令本领域技术人员参照说明书文字能够据以实施。在附图中，为清晰起见，可对形状和尺寸进行放大，并将在所 有图中使用相同的附图标记来指示相同或相似的部件。在下列描述中，诸如前部、背部、后部、左边、右边、顶部、底部、上部、下部等用词均只针对如图1～图3所示的结构分配而言。特别地，“高度”相当于从顶部到底部的尺寸，“宽度”相当于从左边到右边的尺寸，“深度”相当于从前到后的尺寸。这些相对术语是为了说明方便起见并且通常并不旨在需要具体取向。涉及附接、联接等的术语(例如，“连接”和“附接”)是指这些结构通过中间结构彼此直接或间接固定或附接的关系、以及可动或刚性附接或关系，除非以其他方式明确地说明。
参照图1及图2，具有双螺旋尘气分离结构的尘杯包括杯体1以及双螺旋过滤组件2，其中，杯体1内部中空，双螺旋过滤组件2包括两根间隔设置的过滤风柱22，以及两根沿杯体1的高度方向延伸并设置于杯体1内的导风管13，导风管13的内部中空，每根导风管13内均设有过滤风柱22，过滤风柱22通过杯体1上部的敞口插入导风管13内，且过滤风柱22的外侧壁与导风管13的内侧壁之间相隔一定的距离以形成位于两者之间的风道。
参照图2及图4，导风管13偏置地设于杯体1内部的一侧。在一实施方式中，导风管13的外侧壁与杯体1的内侧壁之间形成有用于收集灰尘的集尘空间14。从而杯体1的内部被导风管13分割成位于导风管13内的过滤空间以及位于导风管13外的集尘空间14，通过合理的空间配置使得杯体1内部空间布置简单合理。
参照图1、图2及图3，杯体1的侧壁11上开设有分别通往每根导风管13内部的进风口12。从而使得经由吸尘器吸头吸取的夹杂有灰尘、杂质等其他固体颗粒的空气能够通过进风口12进入导风管13内部的过滤空间，进风口12较靠近杯体1的底部。
参照图2、图4及图5，导风管13呈圆筒形结构，进风口12相对于导风管13的中轴线偏置设置以使得进风方向与导风管13的内侧壁相切。如图4及图5所示，夹杂有固体颗粒的气流经由进风口12进入到导风管13的底部， 由于进风口12与导风管13的内侧壁相切，气流进入到导风管13后在导风管13内侧壁的导引下，气流的前进方向平滑的过度成沿导风管13内侧壁作周向旋转。
参照图6，导风管13的上部开设有通往集尘空间14的甩灰口131。从而使得质量较大的固体颗粒会在离心力的作用下从甩灰口131处甩入集尘空间14中被收集。
参照图2，过滤风柱22的中上部环绕地设有过滤网221，过滤风柱22的顶部敞开形成有通往外界的出风口222。配合设置在过滤风柱22中上部的过滤网221及圆筒形结构的导风管13，使得夹杂有固体颗粒的气流自进风口12进入到导风管13内部后能够在过滤风柱22的外侧壁与导风管13的内侧壁之间的风道内形成螺旋式上升的流动方向。
再次参照图6，双螺旋过滤组件2包括：挡风组件23，并且挡风组件23包括插入到两个出风口222之间的隔风板231以及设于隔风板231末端的挡风板232，挡风板232的两翼分别与两个出风口222相对设置。挡风组件23的隔风板231能够将两个甩灰口131隔断开，防止其中一个导风管13中甩出的固体颗粒被甩入到另一个导风管13中。挡风板232可以阻挡从甩灰口131甩出灰尘的旋转，防止该旋转带动已落入集尘空间14中的灰尘再次扬起。
在本申请的一个实施例中，在杯体1的高度方向上，隔风板231和挡风板232等高，且隔风板231和挡风板232的高度与所述过滤风柱22的高度呈一预设比例。具体的，所述预设比例可以为1比3。所述隔风板231和挡风板232可以是一体成型的也可以是卡接在一起的。所述隔风板231和挡风板232可以按照“T”型的结合在一起，也可以按照“十”字型的结合在一起。在优选的实施例中，所述所述隔风板231和挡风板232按照“T”型的结合在一起。
参照图7所示，双螺旋过滤组件2还可以包括：固定盘21，其固接于过滤风柱22的顶部；挡风组件23固接于固定盘21的下表面，并且过滤风柱 22的顶部贯穿固定盘21使得出风口222与外界相通。在优选的实施方式中，固定盘21呈圆盘形结构。
需要注意的是，在本申请其他实施例中，挡风组件23也可以固接于该具有双螺旋尘气分离结构的尘杯的其他位置，例如，所述挡风组件23可以与导风管(13)固接。
进一步地，固定盘21的顶部设有滤芯3。从而使得残留有细小颗粒的空气从出风口222流出后，经过滤芯3的过滤后的空气变得更洁净，降低对环境造成的二次污染。
进一步地，过滤风柱22通过杯体1上部的敞口插入到杯体1的内部中时，过滤风柱22的底部与杯体1的底壁密封连接，导风管13的顶部与固定盘21的下表面密封连接，从而使得过滤风柱22的底部被杯体1的底壁所密封，导风管13的顶部被固定盘21的下表面所密封。具体的，可以通过过滤风柱22的底部与杯体1的底壁相接触进行密封，或者通过密封圈来密封。在优选的实施方式中，过滤风柱22与导风管13同心设置，从而使得气流在风道内流通时能够减少紊流，提高流速，进一步提高了过滤效率。
工作时，由于导风管13内设有过滤风柱22，过滤风柱22的中上部设有过滤网221，过滤风柱22的顶部设有出风口222，并且进风口12与导风管13的内侧壁相切，从而使得经由吸尘器吸头吸取的夹杂有灰尘、杂质等其他固体颗粒的空气通过进风口12进入导风管13内部的过滤空间后能够被导风管13的内壁引导成螺旋式上升运动，固体颗粒被设于导风管13上部的甩灰口131甩入至集尘空间14中，此时在出风口222处设置滤芯，能够对气流进一步过滤，降低对环境造成的二次污染。
这里说明的设备数量和处理规模是用来简化本发明的说明的。对本发明的应用、修改和变化对本领域的技术人员来说是显而易见的。
尽管本发明的实施方案已公开如上，但其并不仅限于说明书和实施方式中所列运用，它完全可以被适用于各种适合本发明的领域，对于熟悉本领域 的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本发明并不限于特定的细节和这里示出与描述的图例。
