Abstract:
1. A path-conversion valve assembly for a vacuum cleaner, comprising: a tubular valve member rotatably disposed in an air path formed in a vacuum cleaner, the vacuum cleaner having a socket for receiving a hose nozzle and the valve member having a passage that remains unobstructed at all times and places a vacuum source in fluid communication with an air inlet of a suction brush, said valve member further having a protrusion part that extends slantingly from an outer circumference of the valve member; and a resilient member mounted in the air path to resiliently press the rotating valve member in a first direction, wherein the valve member rotates in a second direction opposite the first direction in response to insertion of the hose nozzle into the socket and the hose nozzle presses against the protrusion part of the valve member.
