本发明涉及家电领域， 特别涉及一种旋风分离器。 背景技术
相关技术中的旋风分离器一般包括旋风筒、 置于旋风筒内用于过滤灰尘等污物的中心 过滤器， 以及与旋风筒外侧壁切向连通的导风管。
但是， 由于含尘空气从旋风筒的侧壁向里进风， 导致灰尘容易粘附在中心过滤器上， 导致过滤器堵塞， 而且由于旋风筒一般为圆筒形状， 导致进气管与旋风筒之间的密封性差， 影响吸尘器的吸尘效率， 且部件成本高。 发明内容
本发明旨在至少在一定程度上解决现有技术中的上述技术问题之一。 为此， 本发明的 一个目的在于提出一种旋风分离器， 该旋风分离器采用底部进风， 且含尘空气向远离过滤 器的方向进入旋风筒， 该旋风分离器可用于吸尘器等设备上。
根据本发明实施例的旋风分离器， 包括： 旋风筒、 旋风分离器端盖、 过滤器和导风筒。 具体而言， 所述旋风筒的上端敞开， 且所述旋风筒的底壁上具有旋风分离器入口； 所述旋 风分离器端盖设在所述旋风筒上方， 且所述旋风分离器端盖上设有旋风分离器出口； 所述 过滤器的上端与所述旋风分离器出口连通， 且所述过滤器的下端伸入所述旋风筒内； 所述 导风筒的下端与所述旋风分离器入口连通， 且所述导风筒的上端封闭， 所述导风筒的侧壁 上设有与所述旋风筒连通的通风口。
根据本发明实施例的旋风分离器， 采用底部进风， 且进入旋风分离器的含尘空气向远 离过滤器的方向进入旋风筒内。 由此， 使进入旋风筒内的含尘空气快速的形成螺旋气流， 且使灰尘等在离心力的作用下抛离过滤器， 使灰尘远离过滤器可以避免灰尘粘附在过滤器 上造成过滤器堵塞， 本发明的旋风分离器可以减少过滤器堵塞， 从而延长过滤器的使用时 间， 以及降低过滤器的清洗频率。
另外， 根据本发明上述实施例的旋风分离器， 还可以具有如下附加的技术特征： 根据本发明的一个实施例， 所述旋风筒内设有导风板和挡风板， 所述导风板的至少一 部分向上螺旋延伸， 所述挡风板设在所述通风口上方， 且所述挡风板不高于所述导风板的 上沿。 由此， 采用了气流螺旋向上的导风结构， 使甩灰位置被最大化的上移， 利用高效旋 风分离器， 让含尘气流在导风板上加速上升， 然后被抛出旋风筒， 使尘气分离快速且彻底， 同时毛发等带状物也轻松地甩出，从而减少了经过过滤器排出旋风分离器的尘土和毛发等， 使具有该旋风分离器的吸尘器整机的吸力不再因过滤棉堵塞而很快下降， 将大大提高分离 效率， 延长过滤棉的清洁周期。
根据本发明的一个实施例， 所述导风板为环形， 且所述导风板包括： 第一板体、 第二 板体， 螺旋导风板和连接板。所述第一板体和所述第二板体分别与所述旋风筒的轴线垂直； 所述螺旋导风板沿上下方向螺旋延伸， 且所述螺旋导风板的两端分别与所述第一板体和所 述第二板体相连； 所述连接板与所述旋风筒的轴线平行， 且所述连接板的两端分别与所述 第一板体和所述第二板体相连。 由此， 使导风板的结构简单， 便于成型， 且便于该连接板 对含尘气流进行导流， 以便于含尘气流沿螺旋上升， 而进行尘气分离。
根据本发明的一个实施例， 所述第一板体设在所述通风口的下沿， 所述挡风板设在所 述通风口的上沿， 且所述第二板体与所述挡风板平齐， 所述连接板设在所述通风口的侧沿。 由此， 使含尘气流可以很容易的螺旋上升， 避免气流直接上升导致过滤效果差而堵塞过滤 器， 提高旋风分离器对含尘气流的分离效率和分离效果。 而且使灰尘等抛出可以降低通过 过滤器的灰尘等的量。
根据本发明的一个实施例， 所述导风板为所述旋风筒的底壁， 所述旋风分离器入口形 成在所述导风板上。 由此， 直接采用导风板做旋风筒的底壁， 使旋风筒的结构简单， 便于 旋风筒的成型， 提高旋风筒的成型效率。
根据本发明的一个实施例， 所述旋风筒的底壁上设有与所述旋风分离器入口连通的进 风管。 由此， 便于该旋风分离器连接积尘装置的尘杯， 提高了该旋风分离器的安装效率。
根据本发明的一个实施例， 所述旋风分离器还包括筒体和隔板， 所述隔板设在所述筒 体内， 且所述隔板将所述筒体内部空间沿上下方向间隔开， 所述筒体的上部形成所述过滤 器， 且所述筒体的下部形成所述导风筒。 由此， 导风筒一体形成在过滤器上， 可以简化旋 风分离器的结构， 便于旋风分离器的生产和装配。
根据本发明的一个实施例， 所述导风板的高度不小于所述导风筒深度的一半， 且所述 导风板的高度不大于所述旋风筒的深度。 由此， 提高了旋风筒的导风效果， 便于气流螺旋 上升。
根据本发明的一个实施例， 所述旋风分离器端盖与所述旋风筒的上沿间隔开， 且所述 旋风筒的上沿与所述旋风分离器端盖之间的距离不大于所述导风板的高度。 由此， 便于旋 风筒内分离出的尘土等杂质 360度全方位抛出， 不在限制甩灰位置， 便于该旋风分离器对 含尘气流的分离效果。
根据本发明的一个实施例， 所述过滤器为圆筒形状， 且所述旋风筒为中心线与所述过 滤器的中心线重合的圆筒形状， 所述过滤器的半径不大于所述旋风筒半径的一半。 由此， 便于灰尘杂质被抛出， 避免灰尘等杂质吸附在过滤器上造成过滤器堵塞， 以及避免灰尘通 器后造成滤棉的除尘频率高。 因此， 本发明的旋风分离器可以提高含尘气流的分离

下面参照附图详细描述本发明实施例的旋风分离器， 该旋风分离器可用于吸尘器。 如图 1至图 3所示， 根据本发明实施例的旋风分离器 1， 包括： 旋风筒 11、 旋风分离 器端盖 12、 过滤器 13和导风筒 14。
具体而言， 旋风筒 11的上端敞开， 且旋风筒 11的底壁上具有旋风分离器入口 101， 该 旋风分离器入口 101用于含尘空气进入旋风筒 11， 以便于含尘空气在旋风分离器 1内分离 成空气和灰尘等。旋风分离器端盖 12设在旋风筒 11上方， 且旋风分离器端盖 12上设有旋 风分离器出口 102。 含尘空气通过旋风分离器入口 101被吸入旋风分离器 1 内， 然后经过 旋风分离器 1过滤， 过滤过程中， 灰尘等将被分离抛出旋风筒 11， 而过滤后的空气将经过 旋风分离器出口 102排出。 过滤器 13用于对含尘空气进行过滤， 以使气体通过过滤器 13 排出旋风分离器 1。 过滤器 13的上端与旋风分离器出口 102连通， 且过滤器 13的上端封 闭旋风分离器出口 102 的周沿， 使含尘空气无法通过旋风分离器出口 102， 而只有经过过 滤器 13过滤后的空气通过旋风分离器出口 102排除旋风分离器 1， 过滤器 13的下端伸入 旋风筒 11内。 导风筒 14的下端与旋风分离器入口 101连通， 且导风筒 14的上端封闭， 导 风筒 14的侧壁上设有与旋风筒 11连通的通风口 103， 从而使气流沿旋风筒 11的径向进入 旋风筒 11内， 以便于旋风分离器 1的过滤以及使尘土被抛出旋风筒 11。
根据本发明实施例的旋风分离器， 采用底部进风， 且进入旋风分离器 1 的含尘空气向 远离过滤器 13的方向进入旋风筒内。 由此， 使进入旋风筒 11 内的含尘空气快速的形成螺 旋气流， 且使灰尘等在离心力的作用下抛离过滤器 13， 使灰尘远离过滤器 13可以避免灰 尘粘附在过滤器 13上造成过滤器 13堵塞， 本发明的旋风分离器可以减少过滤器 13堵塞， 从而延长过滤器 13的使用时间， 以及降低过滤器 13的清洗频率。
需要说明书的是， 本发明的旋风分离器 1可用于吸尘器， 但本发明的旋风分离器并非 仅用于此。
此外， 在将该旋风分离器 1与积尘装置的尘杯连接时， 可以便于连接尘杯和旋风分离 器 1的进气管与旋风分离器 1连接， 使进气管与旋风分离器 1密封性好， 且降低成本。
进一步地， 与该旋风分离器连接的尘杯可以为底部进风的尘杯， 也可以不是， 例如将 本发明的旋风分离器设在采用侧进风的尘杯内， 从而是旋风分离器底部的旋风分离器入口 101与尘杯侧壁上的进风口连接。 这对于本领域的普通技术人员是可以理解的。
如图 1至图 3所示， 在本发明的一些实施例中， 旋风筒 11内设有导风板 15和挡风板 16， 导风板 15的至少一部分向上螺旋延伸， 挡风板 16设在通风口 103上方， 且挡风板 16 不高于导风板 15的上沿。 也就是说， 进入旋风筒 11的气流在导风板 15和挡风板 16的作 用下， 可以沿着导风板 15的延伸方向螺旋上升， 由此， 采用了气流螺旋向上的导风结构， 使甩灰位置被最大化的上移，利用高效旋风分离器 1，让含尘气流在导风板 15上加速上升， 然后被抛出旋风筒 11， 使尘气分离快速且彻底， 同时毛发等带状物也轻松地甩出， 从而减 少了经过过滤器 13排出旋风分离器 1的尘土和毛发等，使具有该旋风分离器 1的吸尘器整 机的吸力不再因过滤棉堵塞而很快下降， 将大大提高分离效率， 延长过滤棉的清洁周期。
本领域普通技术人员可以理解的是， 本发明的导风板 15和挡风板 16是为了使含尘气 流螺旋上升， 当然， 本发明实现含尘气流螺旋上升的方案并非仅限于此， 也可以采用现有 技术中其它形式的导风结构， 例如在导风筒内形成螺旋风道等。
进一步地， 如图 2所示， 导风板 15为环形， 且导风板 15包括第一板体 151、第二板体 152、 螺旋导风板 153和连接板 154， 第一板体 151和第二板体 152分别与旋风筒 11的轴 线垂直， 连接板 154与旋风筒 11的轴线平行， 也即是说， 第一板体 151和第二板体 152相 互平行， 且第一板体 151和第二板体 152中的任一个均与旋风筒的轴线垂直， 或者参照图 2, 第一板体 151和第二板体 152均与如图 2中所示的上下方向垂直， 且连接板 154与图 2 中所示的上下方向平行。 螺旋导风板 153沿上下方向螺旋延伸， 即螺旋导风板 153螺旋向 上延伸， 第一板体 151的一端与螺旋导风板 153的下端相连， 且第一板体 151的另一端与 连接板 154的下端相连， 第二板体 152的一端与螺旋导风板 153的上端相连， 且第二板体 152的另一端与连接板 154的上端相连。 由此， 使导风板 15的结构简单， 便于成型， 且便 于该连接板 15对含尘气流进行导流， 以便于含尘气流沿螺旋上升， 而进行尘气分离。
进一步地， 第一板体 151设在通风口 103的下沿， 挡风板 16设在通风口 103的上沿， 且第二板体 152与挡风板 16平齐， 连接板 154设在通风口 103的侧沿。 换言之， 挡风板 16设在通风口 103的上沿， 且连接板 154设在通风口 103的侧沿， 挡风板 16和连接板 154 对气流具有阻挡的作用， 从而使气流依次沿第一板体 151、 螺旋导风板 153第二板体 152 的方向流动， 从而使气流螺旋上升。 或者说， 通过挡风板 16和连接板 154阻挡从通风口 103进入旋风筒 11的气流， 以避免含尘空气直接上升， 使含尘气流可以很容器的沿着导流 板 15的延伸方向螺旋上升， 从而形成螺旋上升的气流， 以便于通过离心力将灰尘抛出。 由 此， 使含尘气流可以很容易的螺旋上升， 避免面气流直接上升导致过滤效果差而堵塞过滤 器， 提高旋风分离器 1对含尘气流的分离效率和分离效果。 而且使灰尘等抛出可以降低通 过过滤器的灰尘等的量。
有利地， 导风板 15为旋风筒 11的底壁， 旋风分离器入口 101形成在导风板 15上， 换 言之， 旋风筒 11包括筒形侧板 111和导风板 15， 导风板 15设在筒形侧板 111内， 且导风 板 15为环形， 环形的导风板 15的中部形成所述旋风分离器入口 101。 由此， 直接采用导 风板 15做旋风筒 11的底壁， 使旋风筒 11的结构简单， 便于旋风筒 11的成型， 提高旋风 筒 11的成型效率。
本领域普通技术人员可以理解的是，本发明的导风板 15也可以不是旋风筒 11的底壁， 例如旋风筒 11为底部封闭的筒形且导风板设在旋风筒 11内。
此外， 也可以采用一块螺旋延伸的板体和连接该螺旋板体首尾两端的连接板配合形成 导风结构。
如图 1和图 2所示， 在本发明的一些实施例中， 旋风筒 11的底壁上设有与旋风分离器 入口 101连通的进风管 17。 由此， 便于该旋风分离器 1连接积尘装置的尘杯， 提高了该旋 风分离器 1的安装效率。
本发明的进风管 17无需采用特殊塑料材料， 从而降低了进风管 17的成型成本。
如图 1至图 3所示， 导风筒 14的下端套设在进风管 17的内壁上， 且进风管 17的内壁 上设有卡凸 171， 且导风筒 14下端的外壁面上设有与卡凸 171卡合的卡槽 141， 通过卡凸 171和卡槽 141的卡合使导风筒 14套设在进风管 17内。 由此， 使导风筒 14套设在进风管 17内壁上， 可以提高导风筒 14与进风管 17的连接处的密封性能， 使导风筒 14可以封闭 进风管 17。 而且， 采用卡凸 171和卡槽 141的配合使导风筒 14与进风管 17相连， 便于导 风筒 14的安装， 提高了旋风分离器的安装效率。
此外， 本领域普通技术人员可以理解的是， 导风筒 14还可以与进风管 17—体形成， 或导风筒 14与进风管 17通过焊接、 螺栓连接、 卡接等连接在一起。
参照图 3， 导风筒 14上还设有滑槽 142， 其中滑槽 142的一端沿螺旋方向延伸至旋风 筒 11的下边沿且敞开， 且滑槽 142的另一端与卡槽 141连通， 在导风筒 14的安装过程中， 将卡凸 171对准滑槽 142敞开的一端， 并转动导风筒 14， 使卡凸 171沿滑槽 142滑入卡槽 141内， 从而使卡凸 171与滑槽 142卡合。
此外， 卡槽 141和卡凸 171为一一对应的多个。
如图 1所示， 在本发明的一些示例中， 旋风分离器 1还包括筒体 18和隔板 19， 隔板 19设在筒体 18内， 且隔板 19将筒体 18内部空间沿上下方向间隔开， 筒体 18的上部形成 过滤器 13， 且筒体 18的下部形成导风筒 14。 换言之， 过滤器 13和筒体 14一体形成。 由 此， 导风筒 14一体形成在过滤器 13上， 可以简化旋风分离器 1的结构， 便于旋风分离器 1的生产和装配。
当然， 导风筒 14和过滤器 13也可以分别形成， 且过滤器 13位于导风筒 14的正上方。 如图 1和图 3所示， 在本发明的一个具体示例中， 过滤器 13与旋风分离器端盖 12— 体形成。 由此， 提高了过滤器 13与尘杯连接处的密封性能， 从而进一步地提高了具有该旋 风分离器的吸尘器的吸力， 便于提高吸尘效率。
如图 1和图 4所示，在本发明的一些实施例中，旋风筒 11的上沿与旋风分离器端盖 12 间隔开。 由此， 便于旋风筒 11内分离出的尘土等杂质 360度全方位抛出， 不再限制甩灰位 置， 便于该旋风分离器 1对含尘气流的分离效果。
进一步地， 过滤器 13和旋风筒 11均为圆筒形状， 且旋风筒 11为中心线与导风筒 14 的中心线重合。
参照图 4， 导风板 15的高度 HI不小于导风筒 14深度 H2的一半， 且导风板 15的高度 HI不大于导风筒 14的深度 H2。 换言之， 0. 5H2 HKH2。 由此， 提高了旋风筒 11的导风 效果， 便于气流螺旋上升。
进一步地， 旋风分离器端盖 12与旋风筒 11的上沿之间的距离 H3不大于导风板 15的 高度 Hl。 由此， 便于尘土等杂质被抛出， 从而不仅可以避免尘土堆积在旋风筒 11 内， 而 且还便于尘土等杂质在尘杯的堆积。
有利地， 过滤器 13的半径 R1不大于旋风筒 11半径 R2的一半， 换言之， 旋风筒 11与 过滤器 13沿径向间隔的距离 R3不小于旋风筒 11半径 R2的一半， 且旋风筒 11与过滤器 13沿径向间隔的距离 R3不大于旋风筒 11半径 R2。 或者说， 旋风筒 11的半径与过滤器 13 的半径之间的差值 R3不小于旋风筒 11半径 R2的一半，且旋风筒 11的半径与过滤器 13的 半径之间的差值 R3不大于旋风筒 11的半径 R2。 即½1?2：^1?1：^1?2。 由此， 便于灰尘杂质被 抛出， 避免灰尘等杂质吸附在过滤器 13上造成过滤器 13堵塞， 以及避免灰尘通过过滤器 13后造成滤棉的除尘频率高。
因此， 本发明的旋风分离器可以提高含尘气流的分离效率。
下面参照图 1至图 4描述本发明的一个具体实施例。 如图 1至图 4所示， 本发明实现旋风分离器 1的高密闭性和高吸力， 同时保证低成本。 具体地， 旋风分离器 1包括： 旋风筒 11、 置于旋风筒 11内中心处的过滤器 13、 位于 过滤器 13上方的旋风分离器端盖 12， 旋风分离器端盖 12与旋风筒 11的上沿之间有间隙， 在旋风筒 11的底部中心位置连接有进风管 17， 含尘气体通过进风管 17进入旋风筒 11后 再经由其内部的导风板 15进行加速旋转， 导风板 15位于进风管 17和过滤器 13之间。
旋风分离器 1的中心下侧位进风结构， 减少功率损失， 同时甩灰位置被最大化的上移， 利用高效旋风分离器， 让含尘气流在螺旋跑道上加速上升， 360 全方位自由抛出， 不再受 限于甩灰位置， 让分离更彻底， 同时毛发等带状物也轻松地甩出， 整机的吸力不再因过滤 棉堵塞而很快下降， 将大大提高分离效率， 延长过滤棉的清洁次数。
本领域普通技术人人员可以理解的是， 旋风分离器端盖 12与过滤器 13可以为一体形 成或形成多个零件后进行组装； 进风管 17、 导风板 15和旋风筒 11可以为一体形成或形成 多个零件后进行组装； 过滤器 13、 旋风分离器端盖 12和进风管 17可以为一体形成或形成 多个零件后进行组装；导风板 15和旋风筒 11可以为一体形成或形成多个零件后进行组装。
在本说明书的描述中， 参考术语 "一个实施例"、 "一些实施例"、 "示例"、 "具体示 例"、 或 "一些示例"等的描述意指结合该实施例或示例描述的具体特征、 结构、 材料或者 特点包含于本发明的至少一个实施例或示例中。 在本说明书中， 对上述术语的示意性表述 不必须针对的是相同的实施例或示例。 而且， 描述的具体特征、 结构、 材料或者特点可以 在任何的一个或多个实施例或示例中以合适的方式结合。 此外， 本领域的技术人员可以将 本说明书中描述的不同实施例或示例进行接合和组合。
