    • An upright vacuum cleaner having a suction path switching unit is provided that includes a cleaner body having and a body frame; a suction inlet body hinged to the body frame; a hose in fluid communication with the body frame and an extension pipe; and a suction path switching unit disposed on the body frame. The suction path has an operating duct elastically arranged on a suction path to be able to slide up and down. As the extension pipe is inserted into or withdrawn from a socket disposed on the body frame, the operating duct selectively diverts the suction path to a first suction path flowing from the suction inlet body to the dust collecting unit or a second suction path flowing from the extension pipe to the dust collecting unit.
    • 提供一种具有吸入路径切换单元的立式吸尘器,其包括:具有吸尘器主体和主体框架; 吸入口体,铰接到主体框架; 与主体框架和延伸管流体连通的软管; 以及设置在所述主体框架上的吸入路径切换单元。 吸入路径具有弹性地布置在吸入路径上以能够上下滑动的操作管道。 当延伸管插入到设置在主体框架上的插座中或从插座中插入时,操作管道选择性地将吸入路径转移到从吸入口主体到集尘单元的第一吸入路径或者从第二抽吸路径 延长管道到集尘单元。
