Definitions

• the purpose of the present invention is to réa ⁇ read an ashtray in which are incorporated in a practical and space-saving manner elements capable of evacuating cigarette smoke when they are placed on the edge of the ashtray and consequently decrease the generation of unnecessary smoke during the burning of the cigarette.
• the subject of the invention is an ashtray comprising on the one hand a bowl intended to receive tobacco ashes and on the other hand a base supporting the bowl, characterized in that the bottom of the bowl has one or more openings and in that the base includes an air conduction device connected to the opening or openings, and associated with one or more fans, this or these being housed in the base so as to suck the smoke by the conduction device and to discharge it through a filter.
• FIG. 1 is an axial sectional view of this embodiment
• FIG. 2 a sectional view on an enlarged scale, showing the construction of the filter.
• the ashtray shown in the drawing is made up of two main parts which are removable, one with respect to the other, a bowl 1 and a base 2.
• the general shape of this ashtray is a circular shape, although we can Also consider a construction whose outer periphery is square or rectangular.
• the central housing of the bowl can also be circular or square, if necessary annular in shape, that is to say with a central pillar.
• the base comprises a vertical peripheral wall on which the also vertical peripheral wall 4 of the bowl 1 fits which engages on a ferrule-shaped extension 5 of the wall 3.
• the bowl 4 has in its central part a housing with a curved bottom 6 which is pierced on its side with a series of openings 7 distributed around its periphery and in its central part with a circular opening of a relatively large diameter 8.
• a crosspiece 9 which supports a circular piece of wire mesh 10 to mail ⁇ the fines for retaining cigarette ash.
• the bowl further comprises along its around a certain number of notches 11 adapted to the shape of cigarettes.
• the base 2 comprises, in addition to the peripheral wall 3 of the feet 12, a lower plate 13, a central cylindrical element 14 rising from the bottom 13 and a flared upward guide wall 15 which is connected along its upper edge 16 with the flank of the housing 6 immediately above the openings 7.
• a peripheral conduit 17 is formed which opens out under the opening 8 and which extends inside the part 14 of the base, so as to plug in an opening 18 made in the bottom 13.
• This opening 18 is closed by a perforated plate 19 which is fixed against the bottom 13 and which may contain a filter 20.
• the rising part 14 of the base supports a guide piece 21 holding in place an electric motor 22 whose output shaft 23 is integral with a wheel fan 24.
• Motor 22 is connected by a conductor 25 to an interlock switch 26 and provided with a button 27 fixed on the outer wall 3 of the base 2.
• One or more pi ⁇ the 28 can be engaged in appropriate housings by hand and other than switch 26.
• the air and consequently the smoke can also be sucked in through the openings 7 and follow the duct 17. If necessary, only the openings 7 could be maintained, the bottom of the bowl being completely closed. In another embodiment, the openings 7 and the duct 15 could themselves be omitted, the only suction being made through the opening 8 and the trellis 10 supported by the spider 9.
• the filter firstly comprises, according to this construction, a rigid frame formed of an aluminum plate 30, of square shape having 9 square openings 31 distributed in 3 rows in its surface. On each side of the frame 30 is bonded a thin sheet 32 and 33 of fibrous material of consti ⁇ tution specially adapted for filtering cigarette smoke. Finally, the free spaces formed by the openings 31 and the thin felt partitions 32 and 33 are filled with granular products 34 which can be chosen as required. They can be products capable of reacting chemically with smoke, such as activated carbon, for example. However, other products can also be incorporated into this mixture, such as bodies capable of giving off a special aroma.
• the filter 20 constructed in the form of a removable plate will be fixed under the base, on the periphery of the conduit 14 so that it can be removed and exchanged easily.
• - _> -
• multiple variants are possible with regard to the external appearance and the arrangement of the elements of the ashtray described.
• a single fan and a single motor one could, if necessary, provide two, three or four.
• the axis of the fans will not necessarily be vertical, but it may also be oblique or even horizontal in the case where the fans are arranged so as to suck the smoke directly through the side walls of the bowl.
• the motor-fan assembly will be supported from its center, where the motor stator is located, by two or three radial arms of circular profile extending between the blades of the fan and the plate.
• contact detectors could be provided in the notches 11 causing the automatic engagement of the fan or fans as soon as a cigarette is placed on the space provided and delimited by one or other of the notches 11.
• the bowl 1 as well as the part of the base 2 which form the structure of this object may be made of molded plastic, or of metal, while the spider 21 and the support plate 19 of the filter 20 will preferably be made of metal, for example aluminum. However, an entirely metallic construction, in stamped sheet metal for example, can also be envisaged. If necessary, the base will be provided with a decor whose appearance has an aesthetic adapted to the intended purpose.
• the visible surfaces of the base can be notched or coated with glossy varnish.
