用于真空吸尘器的抽吸头
摘要：
本发明的用于真空吸尘器的抽吸头包括中空的本体，其包括从本体的预定区域以彼此相对成小于180度的角分叉开的一对臂(1、3)。每个臂被形成为具有用于空气通过的通道(14)，所述通道从臂的自由端延伸到本体中臂分叉开的区域。出口开口(5)位于本体中臂分叉开的区域以使空气通到真空吸尘器。连续的第一接地阻挡件(21)从一个臂(1)的自由端沿该臂的内缘(19)的区域延伸到本体中臂分叉开的区域。连续的第二接地阻挡件(21)从另一个臂(3)的自由端沿该另一个臂的内缘(19)延伸到本体中臂分叉开的区域。间隙(23)在臂分叉开的区域形成在第一和第二阻挡件(21)之间，用以使相对较大的碎屑颗粒通入抽吸头。第一和第二阻挡件(21)适于沿第一和第二阻挡件的整个长度接合平坦的地面。
摘要（英）：

A suction head for a vacuum cleaner of the invention 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 outletopening (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 aninner 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 ofan 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.
