Abstract

An analog electronic component for control of an aerosol delivery device is provided. The aerosol delivery device includes a heating element, a reservoir that retains aerosol precursor composition, and an analog electronic component that in response to user input, and independent of a digital processor, is configured to direct a constant current to the heating element and thereby cause the heating element to activate and vaporize components of the aerosol precursor composition in response to user input, and a user input interface through which the user input is receivable.

First claim

What is claimed is:

1 . An aerosol delivery device comprising:
at least one housing; and contained within the at least one housing, a heating element; a reservoir configured to retain aerosol precursor composition; an analog electronic component that in response to user input, and independent of a digital processor, is configured to direct a constant current to the heating element and thereby cause the heating element to activate and vaporize components of the aerosol precursor composition; a user input interface including a mechanical switch through which the user input is receivable; and a solid state switch operatively coupled to and between the mechanical switch and analog electronic component, and responsive to the user input to switch current to the analog electronic component, and thereby switch the constant current directed by the analog electronic component to the heating element.

2 . An aerosol delivery device comprising:
at least one housing; and contained within the at least one housing, a heating element; a reservoir configured to retain aerosol precursor composition; an analog electronic component, comprising or including a non-inverting operational amplifier, that in response to user input, and independent of a digital processor, is configured to direct a constant current to the heating element and thereby cause the heating element to activate and vaporize components of the aerosol precursor composition; a user input interface including a mechanical switch through which the user input is receivable; and a solid state switch operatively coupled to and between the mechanical switch and analog electronic component, and responsive to the user input to switch current to the analog electronic component, and thereby switch the constant current directed by the analog electronic component to the heating element.

3 . The aerosol delivery device of claim 1 , wherein the solid state switch is a latching switch.

4 . The aerosol delivery device of claim 1 further comprising an indicator operatively coupled between the solid state switch and the analog electronic component, and configured to provide a visual indication of the current being switched.

5 . The aerosol delivery device of claim 4 , wherein the indicator is or includes an organic light emitting diode (OLED) or quantum dot-enabled light emitting diode.

6 . The aerosol delivery device of claim 1 , wherein the user input interface includes a capacitive sensor through which the user input is receivable.

7 . The aerosol delivery device of claim 1 further comprising a single-pole, multiple-throw (SPMT) switch, and a plurality of resistors of varying resistances operatively coupled between the analog electronic component and the heating element, the plurality of resistors being coupled to respective throws of the SPMT switch, the constant current having an amperage that varies depending on which of the throws is connected to the pole of the SPMT switch.

8 . The aerosol delivery device of claim 1 further comprising a rechargeable power source configured to deliver a current from which the analog electronic component is configured to direct the constant current to the heating element.

9 . A control body coupled or coupleable with a cartridge that is equipped with a heating element and contains an aerosol precursor composition, the control body being coupled or coupleable with the cartridge to form an aerosol delivery device, the control body comprising:
at least one housing; and contained within the at least one housing; an analog electronic component that in response to user input, and independent of a digital processor, is configured to direct a constant current to the heating element and thereby cause the heating element to activate and vaporize components of the aerosol precursor composition; a user input interface including a mechanical switch through which the user input is receivable; and a solid state switch operatively coupled to and between the mechanical switch and analog electronic component, and responsive to the user input to switch current to the analog electronic component, and thereby switch the constant current directed by the analog electronic component to the heating element.

10 . The control body of claim 9 , wherein the analog electronic component is or includes a non-inverting operational amplifier or a linear regulator.

11 . The control body of claim 9 , wherein the solid state switch is a latching switch.

12 . The control body of claim 9 further comprising an indicator operatively coupled between the solid state switch and the analog electronic component, and configured to provide a visual indication of the current being switched.

13 . The control body of claim 12 , wherein the indicator is or includes an organic light emitting diode (OLED) or quantum dot-enabled light emitting diode.

14 . The control body of claim 9 , wherein the user input interface includes a capacitive sensor through which the user input is receivable.

15 . The control body of claim 9 , further comprising a single-pole multiple-throw (SPMT) switch, and a plurality of resistors of varying resistances operatively coupled between the analog electronic component and the heating element, the plurality of resistors being coupled to respective throws of the SPMT switch, the constant current having an amperage that varies depending on which of the throws is connected to the pole of the SPMT switch.

16 . The control body of claim 9 further comprising a rechargeable power source configured to deliver a current from which the analog electronic component is configured to direct the constant current to the heating element.
