Abstract

A control body is coupled or coupleable with a cartridge to form an aerosol delivery device, with the cartridge being equipped with a heating element. The control body includes a power source and a microprocessor. The power source is connected to an electrical load that includes the heater when the control body is coupled with the cartridge, and includes a supercapacitor configured to provide power to the electrical load. The microprocessor is configured to operate in an active mode in which the control body is coupled with the cartridge. In the active mode, the microprocessor is configured to direct power from the supercapacitor to the heating element to activate and vaporize components of the aerosol precursor composition.

First claim

What is claimed is:

1. An aerosol delivery device comprising:
an atomizer configured to produce an aerosol from an aerosol precursor composition;
a power source connected to an electrical load that includes the atomizer, the power source comprising a supercapacitor configured to provide power to the electrical load, wherein the supercapacitor is a hybrid capacitor, wherein the power source further comprises:
a DC-to-DC converter connected to the supercapacitor, between the supercapacitor and electrical load;
a snubber circuit connected in parallel with the supercapacitor and thereby forming a parallel combination, the DC-to-DC converter being connected in series with the parallel combination of the snubber circuit and supercapacitor; and
a diode connected to, and between, the DC-to-DC converter and electrical load; and
a microprocessor configured to operate in an active mode in which the microprocessor is configured to direct power from the power source to the atomizer and thereby control the atomizer to activate and produce the aerosol.

2. The aerosol delivery device of claim 1 , wherein the DC-to-DC converter has an input and output, and the diode has an anode and a cathode, and
wherein the input and output of the DC-to-DC converter are connected to respectively the supercapacitor and the anode of the diode, and the cathode of the diode is connected to the electrical load.

3. The aerosol delivery device of claim 1 , wherein the power source further comprises terminals connectable with a source of energy from which the supercapacitor is chargeable.

4. The aerosol delivery device of claim 3 , wherein the power source further comprises the source of energy, and the source of energy is or includes a solid-state battery.

5. The aerosol delivery device of claim 3 , wherein the power source further comprises the source of energy, and the source of energy is or includes a lithium-ion battery.

6. The aerosol delivery device of claim 3 , wherein the power source further comprises a diode connected to the source of energy, between the source of energy and the supercapacitor.

7. A control body for an aerosol delivery device, the control body comprising:
a power source connected to an electrical load, the power source comprising a supercapacitor configured to provide power to the electrical load, wherein the supercapacitor is a hybrid capacitor, wherein the power source further comprises:
a DC-to-DC converter connected to the supercapacitor, between the supercapacitor and electrical load;
a snubber circuit connected in parallel with the supercapacitor and thereby forming a parallel combination, the DC-to-DC converter being connected in series with the parallel combination of the snubber circuit and supercapacitor; and
a diode connected to, and between, the DC-to-DC converter and electrical load; and
a microprocessor configured to operate in an active mode in which the microprocessor is configured to direct power from the power source to the electrical load to cause the aerosol delivery device to produce an aerosol from an aerosol precursor composition.

8. The control body of claim 7 , wherein the DC-to-DC converter has an input and output, and the diode has an anode and a cathode, and
wherein the input and output of the DC-to-DC converter are connected to respectively the supercapacitor and the anode of the diode, and the cathode of the diode is connected to the electrical load.

9. The control body of claim 7 , wherein the power source further comprises terminals connectable with a source of energy from which the supercapacitor is chargeable.

10. The control body of claim 9 , wherein the power source further comprises the source of energy, and the source of energy is or includes a solid-state battery.

11. The control body of claim 9 , wherein the power source further comprises the source of energy, and the source of energy is or includes a lithium-ion battery.

12. The control body of claim 9 , wherein the power source further comprises a diode connected to the source of energy, between the source of energy and the supercapacitor.
