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.

Claims

1. A fragrance dispenser unit comprising:

a housing having a battery power source and a printed circuit board containing a piezoelectric driver circuit powered by said power source;

a piezoelectric cartridge, installable within said housing, said cartridge having

a piezoelectric discharge nozzle with a micro-perforated vibratory plate, said discharge nozzle powered by said driver circuit;

a socket which receives a snap-in fragrance bottle; and

a snap-in fragrance bottle containing an aromatic liquid that snaps into said socket; and

an airtight path leading from the socket to the piezoelectric nozzle, said path including, a horizontal channel beginning at the socket and leading to a vertical wick, which leads to a horizontal wick that is in contact with the vibratory plate.

2. The fragrance dispenser unit of claim 1, wherein said housing has a discharge aperture for the vibratory plate.

3. The fragrance dispenser unit of claim 1, wherein said socket incorporates a truncated semi-cylindrical knife, and said snap-in fragrance bottle has a mouth that is hermetically sealed with a membrane that is pierced by said knife when the bottle is snapped into said socket, thereby releasing the aromatic liquid into the airtight path.

4. The fragrance dispenser unit of claim 1, wherein said truncated semi-cylindrical knife is centered within said socket.

5. The fragrance dispenser unit of claim 1, wherein said snap-in fragrance bottle is disposable when its supply of aromatic liquid is depleted.

6. The fragrance dispenser unit of claim 1, wherein said piezoelectric driver circuitry periodically sends a power pulse to the piezoelectric nozzle, which releases a controlled amount of aromatic liquid into the air with each pulse.

7. A fragrance dispenser unit comprising:

a dispenser housing enclosing a battery power source and a printed circuit board containing a piezoelectric driver circuit powered by said power source, said dispenser housing also having an internal cartridge chamber;

a piezoelectric cartridge installable within said cartridge chamber, said cartridge having

a piezoelectric discharge nozzle having a micro-perforated vibratory plate;

a socket which receives a snap-in fragrance bottle;

a snap-in fragrance bottle containing an aromatic liquid that snaps into said socket; and

an airtight path leading from the socket to the piezoelectric nozzle, said path including, a horizontal channel beginning at the socket and leading to a vertical wick, which leads to a horizontal wick that is in contact with the vibratory plate.

8. The fragrance dispenser unit of claim 7, wherein said socket incorporates a truncated semi-cylindrical knife, and said snap-in fragrance bottle has a mouth that is hermetically sealed with a membrane that is pierced by said knife when the bottle is snapped into said socket, thereby releasing the aromatic liquid into the airtight path.

9. The fragrance dispenser unit of claim 7, wherein said truncated semi-cylindrical knife is centered within said socket.

10. The fragrance dispenser unit of claim 7, wherein said snap-in fragrance bottle is disposable when its supply of aromatic liquid is depleted.

11. The fragrance dispenser unit of claim 7, wherein said piezoelectric driver circuitry periodically sends a power pulse to the piezoelectric nozzle, which releases a controlled amount of aromatic liquid into the air with each pulse.
