Floor nozzle of a vacuum cleaner
First Claim
1. A floor nozzle of a vacuum cleaner, comprising:
- an upper nozzle housing having a portion adapted to be hingedly connected to an intake joint of a vacuum cleaner;
a lower nozzle housing connected to said upper nozzle housing, said lower nozzle housing having an intake opening on a lower side thereof;
a first air passage in said upper and lower nozzle housings and extending between said intake opening and said portion of said upper nozzle housing adapted to be connected to an intake joint of a vacuum cleaner;
a dust collector disposed in said upper and lower nozzle housings, said dust collector having a second air passage therein for communication with said first air passage;
a rotor rotatably mounted in said dust collector and communicating with said second air passage, said rotor comprising a cleaning means for cleaning material from a surface to be cleaned upon rotation of said rotor in one direction, said rotor further comprising means for rotating said rotor in said one direction and an opposite direction in response to movement of said floor nozzle in a first direction and a second direction, respectively, across a surface to be cleaned;
scraper means in said dust collector for removing material from said cleaning means when said rotor is rotated in said opposite direction by movement of said floor nozzle in said second direction; and
a closure means hingedly connected to said dust collector for opening and closing said second air passage to said first air passage.

Abstract
A floor nozzle of a vacuum cleaner is provided with an upper nozzle housing hingedly connected to an intake joint of the cleaner and a lower nozzle housing securely connected to the upper nozzle housing through a bumper, with an intake opening being formed on a lower side of the lower nozzle housing. A first air passage communicating between the intake opening and the intake joint is formed in the upper and lower nozzle housings. A dust collector is accommodated in the nozzle housings, and defines in it a second air passage communicating the first air passage. A thread catcher is so accommodated in the dust collector as to be rotatable in response to forward and rearward movement of the floor nozzle. The thread catcher is capable of catching waste thread on a surface to be cleaned when it rotates upon forward movement of the floor nozzle. A scraper is accommodated in the dust collector for removing the waste thread caught by the thread catcher when the thread catcher rotates upon rearward movement of the floor nozzle. A covering member is hingedly connected to the dust collector for opening or closing the second air passage.
