Abstract

Claims (30)

1 . An electronic device for producing an aerosol for inhalation by a person, comprising:

(a) a cartridge assembly; and

(b) a handheld base assembly;

(c) wherein the cartridge assembly and the handheld base assembly are configured to removably couple together; and

(d) wherein the cartridge assembly comprises,

(i) a mouthpiece; and

(ii) a cartridge comprising a container for containing liquid to be aerosolized and a mesh assembly located on an exterior of the cartridge on top of a lip of a mouth of the container, the mesh assembly comprising a mesh material and a piezoelectric material that vibrates when actuated whereby an aerosol is produced such that the aerosol may be inhaled through the mouthpiece;

(iii) wherein the mouthpiece is attached to the cartridge in covering relation to the mesh assembly such that the aerosol produced by the mesh assembly may be inhaled through an opening in the mouthpiece, the mesh assembly being held in tension seated on top of the lip of the mouth of the container by compressed engagement with an O-ring resulting from the attachment of the mouthpiece to the cartridge; and

(e) wherein the cartridge assembly further comprises a wick comprising a lengthwise channel formed in an exterior surface of the wick and located within and extending between a bottom of the container and the mouth of the container, and wherein the wick is retained in constant contact with the mesh assembly by protuberances proximate the bottom of the container that surround the first end of the wick in a discontinuous circular pattern and receive the end of the wick in frictional fit therewith.

2 . The electronic device of claim 1 , wherein the handheld base assembly comprises circuitry and a power supply for actuating the mesh assembly.

3 . The electronic device of claim 1 , wherein the cartridge assembly and handheld base assembly are configured to magnetically couple together.

4 . The electronic device of claim 3 , wherein the cartridge assembly magnetically mounts onto an end of the handheld base assembly.

5 . The electronic device of claim 1 , wherein screws are utilized in effecting the attachment of the mouthpiece to the cartridge whereby a force by which the O-ring is held in the compressed engagement with the mesh assembly is adjustable.

6 . The electronic device of claim 1 , wherein the first end of the wick is secured by four protuberances that surround the first end of the wick in a discontinuous circular pattern.

7 . A cartridge assembly containing a liquid for producing an aerosol for inhalation by a person, comprising:

(a) a mouthpiece; and

(b) a cartridge comprising a container containing the liquid to be aerosolized and a mesh assembly located on an exterior of the cartridge on top of a lip of a mouth of the container, the mesh assembly comprising a mesh material and a piezoelectric material that vibrates when actuated whereby an aerosol is produced such that the aerosol may be inhaled through the mouthpiece;

(c) wherein the mouthpiece is attached to the cartridge in covering relation to the mesh assembly such that the aerosol produced by the mesh assembly may be inhaled through an opening in the mouthpiece, the mesh assembly being held in tension seated on top of the lip of the mouth of the container by compressed engagement with an O-ring resulting from the attachment of the mouthpiece to the cartridge; and

(d) wherein the cartridge assembly further comprises a wick comprising a lengthwise channel formed in an exterior surface of the wick and located within and extending between a bottom of the container and the mouth of the container, and wherein the wick is retained in constant contact with the mesh assembly by protuberances proximate the bottom of the container that surround the first end of the wick in a discontinuous circular pattern and receive the end of the wick in frictional fit therewith.

8 . The cartridge assembly of claim 7 , wherein screws are utilized in effecting the attachment of the mouthpiece to the cartridge whereby a force by which the O-ring is held in the compressed engagement with the mesh assembly is adjustable.

9 . The cartridge assembly of claim 7 , wherein the first end of the wick is secured by four protuberances that surround the first end of the wick in a discontinuous circular pattern.

10 . The cartridge assembly of claim 7 , the liquid comprises an aqueous formulation, the aqueous formulation comprising:

a saline component;

an acid component, wherein the acid component includes a lactic acid; and

a nicotine component.

11 . The cartridge assembly of claim 10 , wherein the acid component further includes one or more of benzoic acid, malic acid, tartaric acid, salicylic acid, levulinic acid, and hydrochloric acid.

12 . The cartridge assembly of claim 10 , wherein a pH value of the aqueous formulation measures between approximately 2 and approximately 5.

13 . The cartridge assembly of claim 10 , further comprising a menthol component.

14 . The cartridge assembly of claim 13 , further comprising an ethanol component.

15 . The cartridge assembly of claim 13 , further comprising a surfactant component, wherein the surfactant component includes one or more different surfactants, wherein the surfactant component includes one or more of polyoxyethylene sorbitan monooleate, polyoxyethylene sorbitan monostearate, polyoxyethylene sorbitan monolaurate, lecithin, and a poloxamer.
