Abstract

Claims (22)

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

(a) a cartridge assembly configured to aerosolize a liquid to produce the aerosol for inhalation, the cartridge assembly comprising a mouthpiece, a liquid reservoir, and a mesh assembly comprising a mesh material and a piezoelectric material, the mesh assembly arranged to aerosolize liquid from the liquid reservoir within an interior space of the mouthpiece; and

(b) a handheld base assembly removably coupled with the cartridge assembly, the handheld base assembly comprising a pressure sensor and circuitry including a processor or microcontroller and firmware executed by the processor or microcontroller, the handheld base assembly and the cartridge assembly when removably coupled electronically connecting the circuitry and the mesh assembly for controlling actuation of actuating the mesh assembly for aerosolizing liquid from the liquid reservoir within the interior space of the mouthpiece;

(c) wherein the cartridge assembly and the handheld base assembly collectively define an enclosed interior air passageway in fluid communication with the mesh material and extending between the interior space of the mouthpiece to a diaphragm arranged proximate the pressure sensor within the handheld base assembly, by which diaphragm a change in pressure in the enclosed interior air passageway is detected by the pressure sensor when a breath is drawn from the mouthpiece for triggering aerosolization by the mesh assembly.

2 . The electronic device of claim 1 , wherein the interior space of the mouthpiece is vented for facilitating airflow through the interior space.

3 . The electronic device of claim 2 , wherein a port is defined in the mouthpiece for venting the interior space.

4 . The electronic device of claim 1 , wherein the cartridge body defines a portion of the interior air passageway leading from the interior space of the mouthpiece to an opening located on a bottom of a cartridge body of the cartridge assembly.

5 . The electronic device of claim 4 , wherein a channel defined in a cartridge body defines the portion of the interior air passageway leading from the interior space of the mouthpiece to the opening located on the bottom of the cartridge body.

6 . The electronic device of claim 4 , wherein the handheld base assembly comprises a protuberance that defines an opening leading to a portion of the interior air passageway defined by the handheld base assembly, the protuberance extending into the opening located on the bottom of the cartridge body when the handheld base assembly and cartridge assembly are coupled.

7 . The electronic device of claim 6 , wherein a channel defined in the cartridge body defines the portion of the interior air passageway leading from the interior space of the mouthpiece to the opening located on a bottom of the cartridge body.

8 . The electronic device of claim 6 , wherein the handheld base assembly further comprises a sealing component that engages an area around the opening located on the bottom of the cartridge body when the handheld base assembly and cartridge assembly are coupled so as to seal the opening located on the bottom of the cartridge body when the cartridge body is coupled to the handheld base assembly.

9 . The electronic device of claim 8 , wherein the diaphragm closes off the interior air passageway and is located next to and in fluid communication with the pressure sensor.

10 . The electronic device of claim 9 , wherein the diaphragm is configured to trigger the pressure sensor when the diaphragm moves due to a drop in pressure in the interior air passageway.

11 . The electronic device of claim 9 , wherein the protuberance defines the portion of the interior air passageway that extends from the opening in the cartridge body to the diaphragm.

12 . The electronic device of claim 9 , wherein an opening is provided into the portion of the interior air passageway defined by the cartridge assembly, the opening serving as a vent to reduce the pressure drop experienced at the diaphragm in order to avoid a drop in pressure overextending the diaphragm.

13 . The electronic device of claim 9 , wherein an opening is provided into the portion of the interior air passageway defined by the handheld base assembly, the opening serving as a vent to reduce the pressure drop experienced at the diaphragm in order to avoid a drop in pressure overextending the diaphragm.

14 . The electronic device of claim 9 , wherein an opening is provided into the portion of the interior air passageway defined by the cartridge assembly and an opening is provided into the portion of the interior air passageway defined by the handheld base assembly, the openings serving as vents to reduce the pressure drop experienced at the diaphragm in order to avoid a drop in pressure overextending the diaphragm.

15 . The electronic device of claim 14 , wherein the cartridge assembly is disposable.

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

17 . The electronic device of claim 1 , wherein the cartridge assembly magnetically mounts onto an end of the handheld base assembly.

18 . The electronic device of claim 17 , wherein the cartridge assembly is disposable.

19 . The electronic device of claim 1 , wherein the cartridge assembly is disposable.
