Abstract: Rechargeable electric air-freshener for vehicles, of a type which is placed in a lighter holder of these vehicles includes a case, a lid for closing the case, each provided with openings for the perfuming vapor from an aromatic substance, which may be recharged and which, by means of temperature, releases aromatic essences it contains, situated inside the case, two metal bands on sides of the case to hold the case in position, one permitting connection to one electrical pole, a button at a rear portion of the case, a spring inside the case for the other pole, an integrated printed heated electrical circuit in the case, and an external button with four positions for activating the electrical circuit, the external button including an LED visible behind the lid and a switch, which activates a sound alarm to advise of a need to recharge the aromatic substance.

Abstract: An air freshener for motor vehicles, of a type inserted inside an electrical lighter of a vehicle and using current from the electrical lighter, includes a casing for holding an air freshening material of a pastille or gel form therein, the casing having a cover; a main resistor surrounded by the casing and which is electrically activated by the current to generate heat; a printed circuit board with resistors of lower voltage rating than the main resistor and connected to the main resistor; holes in the cover for entry of air; interior projections in the casing for holding the air freshening material; a buzzer placed inside the casing, activated by the current and triggered by a time mechanism corresponding to usage time; two electrical poles for receiving current from the electrical lighter; at least one wire for connecting the two electrical poles with the printed circuit board and/or main resistor; and a light which is illuminated by the current during activation of the main resistor.
