Fragrance dispenser having a disposable piezoelectric cartridge with a snap-in bottle containing aromatic liquid
First Claim
1. A fragrance dispensing system, comprising:
- a dispenser unit including a housing having a power source and a printed circuit board containing a piezoelectric driver circuit powered by said power source; and
a piezoelectric cartridge installable within said housing and including;
a cartridge body;
a piezoelectric discharge nozzle supported by said cartridge body and having a micro-perforated vibratory plate, said discharge nozzle powered by said driver circuit of said dispenser unit when said piezoelectric cartridge is installed within said housing of said dispenser unit;
a fragrance bottle supported by said cartridge body, said cartridge body further having a liquid fragrance path from the bottle to the piezoelectric nozzle, said path including a channel with a wick, said wick in contact with the vibratory plate of the piezoelectric discharge nozzle, said piezoelectric cartridge further including a horizontal channel in fluid communication with the bottle and leading to a vertical portion of the wick, the wick further having a horizontal portion in contact with the vibratory plate.

Abstract
A fragrance dispenser unit has a piezoelectric discharge nozzle and a disposable snap-in air freshener containing aromatic liquid. The dispenser unit incorporates a battery power source and a piezoelectric driver circuit on a printed circuit board. The dispenser unit The cartridge includes a housing and an induction-sealed fragrance bottle that snaps into a socket at the bottom of the housing when the cartridge is to be activated. A membrane seal on the mouth of the bottle is pierced by a knife in the housing as the bottle is snapped into place. Liquid fragrance is directed to a micro-perforated vibratory plate in the piezoelectric nozzle by an airtight path that includes: first, a horizontal channel; second, a vertical wick; and, finally, a horizontal wick.

9. A piezoelectric fragrance cartridge for a fragrance dispenser unit, the fragrance dispenser unit including a housing with a power source and a piezoelectric driver circuit powered by the power source, the piezoelectric fragrance cartridge comprising:
-
a cartridge body; a piezoelectric discharge nozzle supported by the body and including a micro-perforated vibratory plate; a fragrance bottle supported by the body; a liquid fragrance path from the bottle to the piezoelectric nozzle, said liquid fragrance path including a channel with a wick, said wick in contact with the vibratory plate of the piezoelectric discharge nozzle; electrical contacts, wherein the piezoelectric fragrance cartridge is installable in the housing of the fragrance dispenser unit so that the electrical contacts of the piezoelectric fragrance cartridge engage with corresponding electrical contacts of the fragrance dispenser unit thereby enabling the piezoelectric nozzle of the piezoelectric cartridge to be powered by the piezoelectric driver circuit of the fragrance dispenser unit and release a mist of atomized aromatic liquid droplets from the piezoelectric discharge nozzle; and a horizontal channel in fluid communication with the bottle and leading to a vertical portion of the wick, the wick further having a horizontal portion in contact with the vibratory plate. - View Dependent Claims (10, 11, 12, 13)
