Abstract
Method and apparatus for creating a cyclonic action within a cannister. Communication of air between a first truncated conical member with a hole or opening located in its central area and the inside of the lower casing of the cannister takes place using an annulus between the outside of the conical member or, alternatively, by using holes or openings extending through the conical member. Transition areas create lower pressure areas which attract debris laden air downwardly so as to deposit the debris in the lower pressure area of the cannister.
Claims10
A vacuum system comprising:
- (a) a casing having a bottom portion, an inlet disposed above said bottom portion for receiving a flow of air and debris, and an outlet disposed downstream of said inlet;
- (b) impelling means for impelling said flow from said inlet to said outlet;
- (c) first redirection means, disposed downstream from said inlet, for redirecting said flow outwardly and downwardly within said casing;
- (d) second redirection means, disposed downstream from said first redirection means, for directing said flow inwardly and downwardly within said casing toward said casing bottom portion, in an annulus configuration of decreasing diameter as the flow proceeds.
