Abstract

A smoke and odor purifying system which can be incorporated within a housing that can serve both as a table centerpiece and an ashtray. The system having an esthetically pleasing flower vase construction with petal shaped appendages for resting of cigarettes or the like. A floral arrangement is made up of individual artificial flowers. Each flower having an opening in the bud for drawing in smoke-filled air and passing it through the system. Also defined within the petals of the housing are a plurality of intake openings through which cigarette smoke, as well as secondary smoke from the surrounding area may be drawn downwardly through the device. An electrically or battery powered fan means, positioned below a filtration and odor-treatment system, drives the smoke through the system which includes an electrostatic prefiltering bed followed by an activated charcoal bed, an H.E.P.A. filter and finally another activated charcoal bed containing an air freshening material. Refreshed and smoke free air is returned to the surrounding atmosphere through a plurality of exhaust vents located at the bottom of the housing.

Dependent claims

A pure air system, presenting an appearance of an ornamental table centerpiece, comprising:

a hollow housing having an upper portion, a neck portion and a lower portion, the neck portion integrally connecting the upper and lower portions;
the upper portion having means for allowing air to be drawn into the housing;
the upper portion having defined a central opening therein;
the central opening having a cylindrical surface extending downwardly into the neck portion to form a channel thereof;
a floral arrangement having a plurality of flowers extending through the central opening and deposed within the channel;
a circular sieve plate integral with the bottom on the channel, for supporting the floral arrangement, the plate fastened within the housing by a generally circular screen biased against the internal surface of the housing;
each flower having a center bud opening for drawing in air, a removable prefilter deposed in each flower bud and a hollow stem for passing air to the system;
means supported in the lower portion for filtering and refreshening the smoke filled air;
means supported in the lower portion for propelling the smoke through the system;
means supported in the lower portion for powering the propelling means;
and
a plurality of exhaust vents located about the bottom of the lower portion,
whereby the smoke filled air is drawn downwardly from the means in the upper portion and the center openings in the flowers, treated by the filtering means, then returned to the surrounding atmosphere clean and refreshed.

10 more elements

An ashtray system for capturing and substantially eliminating odors of smoke from cigarettes, the ashtray comprising:

a hollow vase-shaped housing;
a plurality of curved petal arms extending outwardly from the upper portion of the housing, each petal arm having extremities that define an intake port leading to a conduit defined by the interior surface of the petal arm, each petal arm having a convex upper surface, adjoining petal arms defining a concave crevice therebetween for holding resting cigarettes;
the upper surface of the housing having defined therein a central opening, a removable ash receptacle deposed within the opening for capturing ashes from cigarettes;
a cylindrical surface extending downward from the central opening defining therein a channel, a generally round sieve plate held in position within the neck portion of the housing by a circular spring biased between the housing internal surface;
a metal sleeve interposed in the lower portion of the housing containing a means for filtering the smoke, a means for propelling the smoke downward through the system and a means for powering the system;
a plurality of exhaust vents located below the metal sleeve;
a generally circular door positioned on the bottom of the housing, a hinge mechanism integral with the door for opening and closing, a latch for securing the door in a closed position;
a removable rubber pad covering the bottom of the housing, the pad providing resistance against slippage and also aiding the dampening of vibrations created by the powering means;
and
a plurality of artificial flowers, each flower having an opening in the bud section, a hollow stem leading downward from the bud, a removable prefilter deposed within the bud opening, the flowers placed within the central opening of the housing and held in position by the channel and supported by the sieve plate,
whereby smoke contaminated air is drawn into the system through the intake ports of the petal arms and the bud openings of the flowers, then driven downward through the filtering means by the propelling means before being exhausted from the housing through the exhaust vents, the returned air being clean and refreshed.
