Abstract:
A vehicle vaporizer comprisingan elongated case having a plug at its distal end, the plug being adapted to be received in the socket of a vehicle cigarette lighter, and a tray receptacle in its proximal end, the tray receptacle having an opening at the proximal end of the case; an electrical resistance heating element electrically connected to terminals on the plug for energization by the vehicle cigarette lighter and positioned in the case adjacent the tray receptacle; a tray received in the tray receptacle for movement axially of the case, adapted to support a porous pad impregnated with a vaporizable substance, and movable out of the tray receptacle through the opening for manual replacement of a pad on the tray and into the tray receptacle for operation, and the tray being movable manually by a user along the tray receptacle to a plurality of axial positions so as to vary the degree of exposure of a pad received on the tray to a thermally induced flow of air produced by the heating element; the case including a slot adjacent a side of the tray receptacle and the tray including a manually engageable lug protruding through the slot and projecting from the case for facilitating manual movement of the tray by the user along the tray receptacle; and ventilation openings in portions of the case on opposite sides of the tray receptacle and in the tray for conduction of the thermally-induced flow of ambient air through the pad.
