An air vane shield 94 is positioned above the upper end of hub 80 and is secured thereto by means of a bolt 96 extending therebetween. A circular heat sensing element 98 is positioned on the upper surface of the wall 76 and extends around the lower end of hub 80 and is electrically connected to the motor 86 by means of a wire 100. Motor 86 is connected to the batteries 102 in compartment 104 formed in the housing 64 by means of a wire 106. Batteries 102 are connected to the heat sensing element or switch 98 by means of a wire 108 extending through bore 110. Heat sensing switch 98 is normally open as indicated in FIG. but the heat from the burning tobacco such as cigarettes 112 will cause the switch 98 to close thereby activating motor 86 inasmuch as the circuit is then completed through the batteries 102 as indicated in FIG. 5.
The ash tray device 14 illustrated in FIGS. 6 and 7 includes a base portion 114 having a removable ash tray 116 mounted thereon. A housing 118 extends upwardly from base portion 14 at one side thereof and has an opening 120 formed in the upper end thereof and an opening 122 formed in the front side thereof. A bore 124 is formed in housing 118 and extends between the openings 120 and 122 as best illustrated in FIG. 7. A screen means detachably closes opening 122 and has a filter means 128 positioned immediately therebehind as viewed in FIG. 7. A motor 130 is mounted in bore 124 and has a fan means 132 secured to its power shaft 134. Motor 130 is connected to batteries 136 and 138 mounted in compartment 140 by means of wires 142 and 144. Compartment 140 is closed by a cap member 146. A shield 148 is secured to the forward side of housing 118 and extends outwardly and downwardly thereform as illustrated in the drawings. As seen in the drawings, shield 148 is positioned over opening 122 and extends outwardly over a portion of the ash tray 116 to aid in the directing of the smoke through the screen openings 126 and filter means 128. The activation of motor 130 by the switch 150 causes fan means 132 to draw the smoke through the screen means 126, filter means 128 and upwardly through bore 124 and outer opening 120'.
The ash tray device 16 illustrated in FIGS. 8 and 9 includes a base portion 152 with a recessed portion 154 formed in the upper central area thereof. A plurality of ash trays 156 are detachably mounted in recesesed area 154 and are each provided with a curved inner wall 158 so as to dene a central open area 160 as illustrated in FIG. 8. Housing 162 is positioned above area 160 and is secured to base portion 152 by a plurality of legs 164 as best illustrated in FIG. 9. A conventional light bulb 166 is mounted in the interior of housing 162 by means of support 168 and is electrically connected to a cord member 170 as indicated in FIG. 9. A filter means 172 is mounted in the upper end of housing 162 and is supported therein by a support member 174 as illustrated in FIG. 9. Filter means 172 may be comprised of a charcoal material and may be impregnated with suitable deodorizing material, air freshening material, incense, etc.
-Each of the embodiments of this invention illustrated in the drawings have a common feature, that is, to purify the smoke being produced by cigarettes in the ash tray. In the device 10, the fan means 50 draws the smoke from the cigarettes upwardly through the filter means 62 and thence upwardly out of the housing 44. In the device 12, the heat from the cigarette 112 will cause switch 98 to close thereby energizing motor 86 which causes fan means to draw the smoke through the openings 84, thence through opening 78, thence through iilter means 74 and outwardly through bores 70. When the cigarettes are put out or are extinguished, the heat in the ash tray will diminish thereby causing the switch 98 to open thereby deactivating motor 86.
The ash tray device 14 draws the smoke from the ash tray through the filter means 128 and upwardly through bore 124 and outwardly through opening 120. In ash tray device 16, the heat from the light bulb 166 will cause the draft to move upwardly through the housing 1162 thereby inducing the smoke to pass upwardly through the housing 162 and through the iilter means 172 thereby purifying and treating the air. Preferably, light bulb 166 is used in the embodiments seen in FIGS. 8 and 9 but if not used, the heat from the cigarettes will tend to create an upward draft through the housing 162.
*In each of the embodiments seen in the drawings, the smoke from the cigarettes is passed through the lter means comprised of charcoal or the like thereby purifying the same so that no visible smoke is seen to be discharged on the exhaust side of the filter means. Additionally, the filter means disclosed in these embodiments can be supplemented with air deodorizing materials, air freshening materials, incense or the like if it is desired to additionally treat the air passing through the respective devices. The ash tray devices 10, 12 and 14 have been described as utilizing batteries but it can be appreciated that the batteries could be eliminated as simply utilizing volt A. C. current.
The devices disclosed herein also aid in extinguishing the cigarettes which are placed in theash tray due to the fact that the fan means causes the air to be drawn away from the cigarettes which decreases the available oxygen adjacent thereto so that the cigarettes will extinguish themselves due to the lack of available oxygen. While the devices described herein are ideally suitable for use on a table or the like, it can be appreciated that the concept disclosed herein could be used in conjunction with a vehicle ash tray or the like. Additionally, the devices illustrated herein could be incorporated into Ia desk unit having other electrical apparatuses attached thereto if so desired.
While the embodiments described herein are ideally suited for use as ash trays, it should also be noted that the ltering systems can be employed without the ash trays included therein. For example, the device 10, without the ash tray 20, can be used on a desk or the like to constantly lter and purify the air in an oifice or room.
Thus it can be seen that the devices accomplish at least all of their stated objectives.
Some changes may be made in the construction and arrangement of -my ash tray device without departing from the real spirit and purpose of my invention, and it 5 is my intention to cover by my claim, any modified discharged out through said housing exhaust opening forms of structure or use of mechanical equivalents which to the atmosphere. may be reasonably included within their scope.
