    • A vacuum cleaner includes a first housing defining a cyclonic airflow chamber and a second housing defining a main suction opening that is in communication with an inlet of the cyclonic chamber. A suction source has a suction airstream inlet in communication with an outlet of the cyclonic chamber, and establishes a suction airstream that enters said main suction opening, passes through said cyclonic chamber, and passes to an outlet of said suction source. A substantial portion of particulates entrained in the suction airstream are separated therefrom when said suction airstream moves in a cyclonic fashion through the cyclonic chamber. A main filter assembly, preferably including filter medium comprising polytetrafluoroethylene (PTFE), is located in the cyclonic chamber so that a suction airstream moving from the main suction opening to the inlet of said suction source by way of the cyclonic airflow chamber passes through the filter medium thereof after said airstream moves in a cyclonic fashion within the cyclonic airflow chamber to remove residual particulates from the suction airstream before it leaves the cyclonic chamber. A HEPA filter can be provided to filter the suction airstream exhausted through the outlet of the suction source prior to the airstream being discharged from the vacuum.
    • 真空吸尘器包括限定旋风气流室的第一壳体和限定与气旋室的入口连通的主吸入口的第二壳体。 抽吸源具有与旋流室的出口连通的吸入气流入口,并且建立进入所述主吸入口的吸入空气流,通过所述旋风室,并且通过所述吸入源的出口。 当所述吸入气流以气旋方式移动通过旋风室时,夹带在吸入气流中的大部分微粒被分离。 优选包括聚四氟乙烯(PTFE)的过滤介质的主过滤器组件位于旋风室中,使得通过旋风气流室从主吸入口至所述吸入源的入口移动的吸入空气通过过滤器 所述气流在气旋气流室内以气旋方式移动,以在离开旋风腔室之前从吸入空气流中除去残留的微粒。 可以提供HEPA过滤器,以在气流从真空排出之前过滤通过吸入源的出口排出的吸入空气。

    • A surface cleaning suction type appliance comprises a housing, an airstream suction source, a cyclone main body, and a dirt cup. The housing includes a main suction opening. The airstream suction source is mounted to the housing and includes a suction airstream inlet and a suction airstream outlet. The suction source selectively establishes and maintains a flow of air from the main suction opening, via the airstream inlet, to the airstream outlet. The cyclone main body is supported by the housing and is in communication with the main suction opening. The cyclone main body has a uniform outer circumference and includes a first stage separator, and a plurality of downstream second stage separators. The lengths of the second stage cyclonic separators are different for any number of adjacent pairs of separators from on pair up to all adjacent pairs of separators. The dirt cup is connected to the cyclone main body. The dirt cup includes a first particle collector and a second particle collector. The first particle collector communicates with the first stage separator for collecting dust particles from the first stage separator. The separate second particle collector communicates with the plurality of second stage separators for collecting dust particles from the second stage separators.
    • 表面清洁抽吸式器具包括壳体,气流吸入源,旋风主体和污物杯。 壳体包括主吸入口。 气流吸入源安装在壳体上,包括一个吸入空气流入口和一个吸气流出口。 抽吸源选择性地建立并保持来自主吸入口的空气经由气流入口流到空气流出口。 旋风主体由壳体支撑并与主吸入口连通。 旋风主体具有均匀的外圆周,并且包括第一级分离器和多个下游第二级分离器。 第二级旋风分离器的长度对于从成对到所有相邻的分离器对的任何数量的相邻的分离器对而言是不同的。 污物杯连接到旋风主体。 污物杯包括第一颗粒收集器和第二颗粒收集器。 第一颗粒收集器与第一级分离器连通,用于从第一级分离器收集灰尘颗粒。 分离的第二颗粒收集器与多个第二级分离器连通,用于从第二级分离器收集灰尘颗粒。
