Abstract

Claims (13)

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

(a) a cartridge assembly comprising

(i) a cartridge housing, a bladder contained within the cartridge housing, a pressure ring, and a mesh assembly located at a top of a distal end of the cartridge housing, the mesh assembly being sandwiched between a mouth of the bladder and the pressure ring and held in sealing engagement with the bladder, and

(ii) a mouthpiece attached to the distal end of the cartridge housing in opposing facing relation to the mesh assembly such that an enclosed interior space is defined by and between the mouthpiece and the distal end of the cartridge housing, the enclosed interior space extending over the mesh assembly, into which enclosed interior space the mesh assembly produces aerosolized liquid from liquid in the bladder, the mouthpiece further defining

(A) a mouthpiece opening through which the aerosolized liquid is suctioned from the enclosed interior space into a mouth of a person when a breath is drawn,

(B) a port in a side of the mouthpiece leading into an antechamber that is defined by and between the mouthpiece, the pressure ring, and the cartridge housing, and

(C) an interior opening between the antechamber and the enclosed interior space for facilitating airflow through the port and antechamber into and through the enclosed interior space and out of the mouthpiece opening when the breath is drawn,

(iii) wherein the cartridge housing defines an enclosed air channel extending from the antechamber to an opening in a bottom surface of a proximal end of the cartridge housing, the proximal end of the cartridge housing being opposite the distal end of the cartridge housing; and

(b) a handheld base assembly removably coupled with the cartridge assembly and comprising a protuberance extending through the opening in the bottom surface of the proximal end of the cartridge housing into the enclosed air channel defined by the cartridge housing, the protuberance defining an enclosed air passageway leading to a diaphragm that seals off the air passageway and that is located proximate a pressure sensor contained within the handheld base assembly, by which a change in pressure in the enclosed air channel of the cartridge housing is detected by the pressure sensor.

2. The electronic device of claim 1 , wherein the handheld base assembly further comprises a sealing component that engages the area around the opening on the bottom surface of the proximal end of the cartridge housing and that thereby seals in airtight manner the opening with the protuberance extending therein.

3. The electronic device of claim 1 , wherein the electronic device comprises electronic components, none of which are exposed to the enclosed interior space, the antechamber, the enclosed air channel, or the enclosed air passageway.

4. The electronic device of claim 1 , wherein the handheld base assembly is magnetically coupled with the cartridge assembly.

5. The electronic device of claim 1 , wherein the pressure sensor is mounted on a printed circuit board of the handheld base assembly.
