Smokeless ashtray system

Abstract

A smokeless ashtray system includes a vacuum manifold connecting a plurality of ashtrays to a charcoal filter and a vacuum blower/motor assembly. The vacuum manifold includes spiral wound metal flexible metal tubing segments secured to connectors by heat shrink tubing. L connectors connect end most ashtray locations to the manifold, T connectors connect intermediate ashtray locations, and a four-way connector connects a central ashtray location to the manifold and to the charcoal filter and blower/motor assembly. Each ashtray location includes a flue member having a first end threaded into the associated connector and a second end inserted within a recess formed centrally in a bottom surface of a cup-shaped ashtray. A connector mounting bracket includes locating apertures engaging alignment pins extending from a flat upper surface of the connector, and a flange on the flue member clamps the bracket to the connector. Screws secure mounting flanges of the bracket to the underside of a table or other mounting surface. A central chimney in the ashtray includes a shield dome covering an open top end to prevent ashes and other debris from entering the air flow path. A replaceable disposable coalescing filter element in the flue member filters smoke prior to passage into the manifold, thus substantially reducing tar fouling of the system. A control box includes an on/off switch, a power on LED, and a service needed LED activated by monitoring load on the motor to indicate filter clogging.
