  • a filter and a fan are provided.
  • most of the particles of the smoke of tobacco are not caught but scatter around because the diameter of each of the particles is as small as 0.3 ⁇ m or less.
  • the present invention was made in order to pro­vide an ashtray which efficiently catches the smoke of tobacco put thereon, to keep the smoke from scattering around.
  • an object of the present invention to provide an ashtray comprising a small electrode; a large electrode; and a mechanism for applying a high voltage between both the electrodes.
  • It is another object of the present invention to provide an ashtray comprising an ash reception plate; a small electrode provided over the ash recep­tion plate at a distance therefrom; an auxiliary electrode opposed to the small electrode; a large electrode electrically coupled to the auxiliary electrode; and a mechanism for applying a high voltage between the small electrode and the auxiliary electrode and between the small electrode and the large electrode.
  • an ashtray comprising an ash reception plate; a cylindrical member extending upward through the ash reception plate; a cover provided over the cylindrical member at a prescribed distance therefrom and covering the upper portion of the ash reception plate; a small electrode facing or communicating with the interior of the cylindrical member; a large electrode; and a mechanism for applying a high voltage between the small electrode and the large electrode.
  • an ashtray comprising a base having an upper opening; an ash reception plate mounted detachably on the bottom surface of said base; a cover pivoted rotatably on said base for closing the upper opening of said base; a guide member engaged detachably with said cover; a small electrode provided on said guide member so as to face the upper surface of said ash reception plate; a frame electrode provided on said guide member adjacent said small electrode; a plate electrode provided on said guide plate so as to face a side surface of said ash reception plate; and a mechanism for applying a high voltage between said electrodes.
  • FIGS. 1, 2 and 3 show an ashtray which is a first embodiment of the present invention and has an ash reception plate 1 and a base 2 therefor.
  • the ash reception plate 1 constituting a large electrode is made of an electroconductive material such as a metal plate (large electrode) .
  • Needle-like electrodes 3 constituting small electrodes are provided over the ash reception plate 1 at a distance therefrom and held by an arm 4 on the base 2.
  • a high voltage from a high-voltage power supply 5 provided in the base 2 is applied between the ash reception plate 1 and the needle-like electrodes 3 through an insulated electric wire not shown in the drawings.
  • FIG. 4 shows the high-voltage power supply 5 in which a DC voltage of 12 V is converted into a high-­frequency signal by an oscillation circuit 6; the high-­frequency signal is applied to the primary coil of a boosting transformer 8 through a feedback circuit 7; and an AC voltage of 5.0 kV from the secondary coil of the transformer 8 is rectified by a voltage doubler rectifier 9 to produce a DC output voltage of 6.5 kV, for example.
  • a commercial AC voltage may be used instead of the DC voltage of 12 V.
  • the AC voltage from the secondary coil of the boosting transformer 8 may be directly applied between the electrodes 1 and 3 instead of the DC output voltage of 6.5 kV.
  • FIGS. 1, 2 and 3 Shown at 10 in FIGS. 1, 2 and 3 is a push-button power switch provided in a circuit through which the DC voltage of 12 V is applied to the oscillation cir­cuit 6.
  • a lamp inside the push button is lit so that it is possible to confirm by eyesight whether the switch 10 is turned on or off.
  • FIGS. 5, 6 and 7 show an ashtray which is a second embodiment.
  • a cover 11 constituting a large electrode made of an electroconductive material is provided so that the cover surrounds needle-like electrodes (small electrodes) 3.
  • a high voltage is applied between the cover 11 and the needle-like elect­rodes 3 as in the first preferred embodiment.
  • FIGS. 8, 9 and 10 show an ashtray which is a third preferred embodiment.
  • a frame-­like electrode 12 constituting an auxiliary electrode, whose cross section is oblong or circular, is provided beside needle-like electrodes 3 at a distance there­from.
  • a plate electrode 13 constituting a large electrode bent as U-shape or as arc is integrally coupled to the frame-like electrode 12 so that the flat or curved surface of the plate electrode 13 faces the side surface of an ash reception plate 1.
  • a high voltage from a high-voltage power supply 5 provided in a base 2 is applied between the needle-like elect­rodes 3 and the frame-like electrode 12 or the plate electrode 13 through an insulated electric wire not shown in the drawings.
  • FIG. 11 shows an ashtray which is a fourth embodiment.
  • parallel plate electrodes 14 are provided as auxiliary electrodes at vertical distances from one another instead of the frame-like electrode 12 provided in the third preferred embodi­ment.
  • the parallel plate electrodes 14 are hung by nonelectroconductive members (not shown in the drawings) from an arm 4 and connected to a plate electrode 13 through electroconductive members (not shown in the drawing). It is preferable to place needle-like elect­rodes 3 at the average height of the parallel plate electrodes 14. The same effect is produced by the fourth preferred embodiment as the above-described embodiments.
  • FIGS. 12 and 13 show an ashtray which is a fifth preferred embodiment.
  • an annular electrode 15 is provided as an auxiliary electrode to face needle-like electrodes 3 and located in the middle of a space surrounded by a cover 11 as in the second preferred embodiment.
  • the annular electrode 15 is supported by electroconductive members 16 on the cover 11. The same effect is produced by the fifth embodi­ment as the above-described preferred embodiments.
  • FIG. 14 shows an ashtray which is a sixth embodi­ment.
  • a cylindrical member 17 extending upward through an ash reception plate 1 is provided.
  • a cover 18 is provided over the cylindrical member 17 at a prescribed distance therefrom and covers the ash reception plate 1.
  • Needle-like electrodes 3 are located under the cylindrical member 17 to face the interior thereof.
  • a plate electrode 13 is located under the ash reception plate 1. The smoke of tobacco goes up from the ash reception plate 1 and is then transferred below the ash reception plate 1 through the cylindrical member 17 and caught on the plate electrode 13 by attraction.
  • the needle-like electrodes 3 may be made up of either a single electrode or a plurality of electrodes spaced apart one another.
  • the electrodes 3 may also be shaped as a ball, a rod, a spicule or saw teeth.
  • the frame-­like electrode 12 may be reticulate.
  • the plate elect­rode 13 may have projections and recesses or be reticulate.
  • an insulating ash reception plate 1 is mounted detachably on the bottom surface of a box-shaped base 2 having an upper opening, and a cover 23 comprising a horizontal plate 23a for closing the upper opening of said base 2 and a vertical plate 23b is pivoted rotatably on the rear portion of said box-shaped base 2 at the substantial central portion of said vertical plate 23b.
  • a DC power supply 5 of several KV is fixed on the back of said vertical plate 23b, a cathode terminal 5a of the power supply 5 is provided on the lower surface of the horizontal plate 23a of said cover 23 and an anode terminal 5b is provided on the front surface of the vertical plate 23b.
  • Guide plates 27 extending in the lower direction are formed at both sides of the horizontal plate 23a of said cover 23.

  • An annular or rectangular frame electrode 12 is provided at a portion backwards of the needle-like electrode 3 on the intermediate lower surface of said guide plate 28 and a plate electrode 13 extending in the lower direction is connected to said annular frame electrode, so that in the state that the guide plate 28 is mounted on the opening and closing cover 23 said plate electrode 13 is brought into contact with the anode terminal 5b of said power supply 5 and faced to a side surface of said ash tray 1.
  • an opening 22 communicating with an upper portion of said ash reception plate 1 is provided on a lower back portion of the base 2.
  • a timer (not shown) is provided for maintaining ON state of a power switch 10 through a predetermined time, such as five minutes when the power switch 10 is turned on.
