A self-acting device for filtering the smoke commonly associated with cigarettes and cigars includes an ashtray which supports a shroud for confining smoke. The shroud in turn supports a motorized fan which creates a flow of air to carry the smoke. In close proximity to the fan and also supported by the shroud is a detector which acts to sequentially sense the smoke and activate the fan motor. A portion of the detector also serves to separate a certain amount of the smoke from the air. Smoke which remains is further drawn upwards by the suction forces created by the fan through a filter before the filtered air is ultimately propelled into the immediately surrounding environment.

A self activating smoke sorbing and filtering device comprising: an ashtray including a wall terminating in a rim for supporting an object having a smoke producing end, such as a cigarette or the like, such that the smoke producing end is positioned within the ashtray, a shroud contacting the wall of the ashtray, said shroud including wall means extending above the ashtray and operative to confine within the shroud the smoke produced by the object positioned within the ashtray and including an aperture in the upper end of said shroud, said shroud having an opening in the wall means thereof such that the shroud contacts only a portion of the wall of the ashtray such that the smoke producing object may be inserted through the opening to rest within the ashtray, said opening defining spaced side walls of the shroud which are recessed back to expose a portion of the rim of the ashtray forward of said side walls, housing means supported solely by said shroud, said housing means having an opening generally vertically above the ashtray and said opening being in communication with said aperture, said housing means including a discharge opening spaced from said opening of said housing means and cooperating with said opening in the wall means to form a passageway extending into said housing means from the outside environment, power driven air moving means supported within said housing means and on said shroud and positioned over said opening in said housing means and within said passageway for drawing air through the opening in the wall means of said shroud and into said passageway for discharge through the opening in said housing means through the remainder of said passageway and through the discharge opening and into the environment, the movement of air through said shroud being operative to carry with it the smoke produced by said object within the confines of the shroud, detection means supported inside said shroud and contiguous to said housing means coupled electrically to said power driven air moving means for detecting smoke and purifying air, said means, on sensing said smoke, being operative to concurrently separate said smoke from said air and energize said air moving means for drawing the smoke and air through said passageway and said detection means and propelling the purified air into the environment, and, filter means supported within said housing means and radially outward of said air moving means above said detection means for filtering the once-purified air drawn through said passageway by said power driven air moving means.
