Air freshner for motor vehicles

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.
