TODAYS PATENT- CYCLONE CHAMBER WITH VORTEX SHIELD

The Cyclone Chamber with Vortex Shield was invented by Yiu-Ming Lee on the 21^st of October 2010, bearing patent number US20100263341A1.

The above invention is a cyclone chamber for a vacuum cleaner includes a cylindrical wall defining an internal cavity. An inlet port extends tangentially from the wall such that air entering the cavity via the inlet port causes a cyclonic flow to develop within the chamber. An exit tube extends axially from the chamber and has a flared opening presented into the chamber. A vortex shield is centred axially within the chamber adjacent to the opening and extends radially from the opening toward the wall. The vortex shield forms a barrier to prevent in the most part, large but light weight particles, carpet fibres and the like from escaping into the exit tube.
