Abstract

A method of controlling a heater of a nicotine e-vapor device includes detecting, from a removable pod included in the nicotine e-vapor device, power information indicating a first power level and a second power level; and supplying power to the heater based on the detected power information by determining a first amount of power based on the first power level, supplying the first amount of power to the heater during a first operation mode of the heater, determining a second amount of power based on the second power level, and supplying the second amount of power to the heater during a second operation mode of the heater, the second amount of power being higher than the first amount of power.

Claims (43)

1. A method of controlling a heater of a nicotine e-vapor device, the method comprising:

detecting, from a removable pod included in the nicotine e-vapor device, power information indicating a first operating point and a second operating point, the power information including a plurality of operating points that correspond, respectively, to a plurality of coarse preference levels, the plurality of operating points including the first operating point and the second operating point;

receiving, via one or more touch sensors located on the nicotine e-vapor device, a selection of a coarse preference level from among the plurality of coarse preference levels;

selecting an operating point from among the plurality of operating points that corresponds to the selected coarse preference level as the second operating point; and

supplying power to the heater based on the detected power information by,

determining a first amount of power based on the first operating point,

supplying the first amount of power to the heater during a first operation mode of the heater,

determining a second amount of power based on the second operating point, and

supplying the second amount of power to the heater during a second operation mode of the heater,

the second amount of power being higher than the first amount of power.

2. The method of claim 1 , wherein,

the first amount of power supplied during the first operation mode is an amount that causes the heater to heat a nicotine pre-vapor formulation stored in the nicotine e-vapor device to a temperature below a boiling point of the nicotine pre-vapor formulation, and

the second amount of power supplied during the second operation mode is an amount that causes the heater to heat the nicotine pre-vapor formulation stored in the nicotine e-vapor device to a temperature equal to, or greater than, the boiling point of the nicotine pre-vapor formulation.

3. The method of claim 2 , wherein the nicotine pre-vapor formulation is stored in the removable pod.

4. The method of claim 2 , wherein the removable pod includes the heater.

5. The method of claim 1 , wherein the determining of the second amount of power comprises:

receiving, by the nicotine e-vapor device from an external device, a selection of a fine preference level from among a plurality of fine preference levels; and

determining the second amount of power based on the second operating point and the selected fine preference level.

6. The method of claim 5 , wherein the external device is a wireless communication device, and the receiving of the selection of the fine preference level comprises:

receiving, by the nicotine e-vapor device, the selection of the fine preference level via a wireless communication link between the nicotine e-vapor device and the external device.

7. The method of claim 1 , wherein the plurality of operating points includes a first plurality of operating points, and

the method further comprises:

receiving, via the one or more touch sensors located on the nicotine e-vapor device, a selection of a second coarse preference level from among the plurality of coarse preference levels; and

selecting an operating point from among the first plurality of operating points that corresponds to the selected second coarse preference level as the first operating point.

8. The method of claim 7 , wherein the determining of the first amount of power comprises:

receiving, by the nicotine e-vapor device from an external device, a selection of a fine preference level from among a plurality of fine preference levels; and

determining the first amount of power based on the first operating point and the selected fine preference level.

9. The method of claim 8 , wherein the external device is a wireless communication device, and the receiving of the selection of the fine preference level comprises:

receiving, by the nicotine e-vapor device, the selection of the fine preference level via a wireless communication link between the nicotine e-vapor device and the external device.

10. The method of claim 8 , wherein

the plurality of operating points further includes a second plurality of operating points, and

the selecting the operating point from among the plurality of operating points includes selecting the operating point from the second plurality of operating points.

11. The method of claim 10 , wherein the determining of the second amount of power comprises:

determining the second amount of power based on the second operating point and the selected fine preference level.

12. The method of claim 11 , wherein the external device is a wireless communication device, and the receiving of the selection of the fine preference level comprises:

receiving, by the nicotine e-vapor device, the selection of the fine preference level via a wireless communication link between the nicotine e-vapor device and the external device.

13. The method of claim 1 , wherein the detecting of the power information comprises:

reading, by the nicotine e-vapor device, the power information from an image located on the removable pod.

14. The method of claim 13 , wherein the image includes a QR code, and the reading of the power information comprises:

reading, by the nicotine e-vapor device, the power information from the QR code located on the removable pod.

15. The method of claim 1 , wherein,

the detecting of the power information comprises:

reading, by the nicotine e-vapor device, the power information from memory of the removable pod.
