    • Disclosed is an upright-type electric vacuum cleaner which comprises a suction port body provided with a rotary brush and a main body case supported tiltably on the suction port body. Improvements are made in details such as the arrangement for supporting the main body case in the suction port body, the arrangements of mounting a handle onto the main body case, the configuration of a main body duct, the arrangement of a rotary brush, the arrangement of a cover of the main body case, and the arrangement of a T-shaped joint for connecting the main body duct and a dust filter means, thereby increasing the strength and rigidity of each of these parts and improving the performance of the vacuum cleaner.
    • 公开了一种立式电动吸尘器,其包括设置有旋转刷的吸入口主体和可倾斜地支撑在吸入口主体上的主体壳体。 详细地进行了改进,例如用于支撑吸入口主体中的主体壳体的布置,将手柄安装在主体壳体上的布置,主体导管的构造,旋转刷的布置,布置 的主体壳体的盖体,以及用于连接主体导管和防尘过滤器装置的T形接头的布置,从而增加了这些部件的强度和刚度,并提高了真空吸尘器的性能。
