    • A suction head for a vacuum cleaner comprises a hollow body including a pair of arms (1, 3) which diverge from a predetermined region of the body at an angle less than 180 degrees relative to each other. Each arm is formed with a channel (14) for the passage of air, the channel extending from the free end of the arm to the region of the body from which the arms diverge. An outlet opening (5) is located in the region of the body from which the arms diverge for the passage of air to a vacuum cleaner. A first continuous ground-engaging barrier (21) extends along the region of an inner edge (19) of one of the arms (1) from the free end of the arm to the region of the body from which the arms diverge. A second continuous ground-engaging barrier (21) extends along the region of an inner edge (19) of the other of the arms (3) from the free end of the arm to the region from which the arms diverge. A gap (23) is formed between the first and second barriers (21) in the region from which the arms diverge for the passage of relatively large particles of debris into the suction head. The first and second barriers (21) are adapted to engage a flat ground surface along the entire length of the first and second barriers.
    • 用于真空吸尘器的抽吸头包括中空体,该中空体包括一对相对于彼此以小于180度的角度从本体的预定区域分叉的臂(1,3)。 每个臂形成有用于空气通过的通道(14),该通道从臂的自由端延伸到臂发射的身体的区域。 出口开口(5)位于主体的区域中,臂从该区域发散以使空气通过到真空吸尘器。 第一连续地面接合障碍物(21)沿着臂(1)中的一个的内边缘(19)的区域从臂的自由端延伸到臂的发散区域。 第二连续地面接合障碍物(21)沿臂的另一个的内边缘(19)的区域从臂的自由端延伸到臂发散的区域。 在第一和第二阻挡层(21)之间形成有间隙(23),在该区域中臂发散以使相对大的碎屑颗粒通过到吸头中。 第一和第二屏障(21)适于沿着第一和第二屏障的整个长度接合平坦的地面。

    • A collection container (40) for matter picked up by a suction cleaner comprises a generally cylindrical body (45) into which an inlet tube (46) extends upwardly from the base (43) thereof. To enable the collection container to be adapted for the collection of either liquids or solids entrained in air flow induced through the inlet tube (46), two interchangeable separator units (60, 70) are provided. Separator unit (60), for use in the wet mode, comprises a tube (61) which forms an extension of the suction tube (46), with a baffle wall (64) over the open mouth thereof, and additionally an oblique annular baffle plate (66) may be provided in the vicinity of the junction between the two tubes (46, 61). The separator unit (70), for use in the dry mode, comprises a mounting ring (72) carrying a tubular filter element (71), the lower end of which is closed by a baffle plate (73) which registers with the open end of the inlet tube (46) in spaced relation thereto.
    • 用于由抽吸清洁器拾取的物品的收集容器(40)包括大致圆柱形的本体(45),入口管(46)从其底部(43)向上延伸到其中。 为了使收集容器适于收集通过入口管(46)感应的空气流中夹带的液体或固体,提供了两个可互换的分离器单元(60,70)。 用于湿式模式的分离器单元(60)包括形成吸管(46)的延伸部的管(61),在其敞开的口上具有挡板(64),另外还有一个斜环形挡板 板(66)可以设置在两个管(46,61)之间的接合处附近。 用于干燥模式的分离器单元(70)包括承载管状过滤器元件(71)的安装环(72),其下端由挡板(73)封闭,挡板(73)与开口端 的入口管(46)。
