Abstract

An aerosol-generating device has a body configured to receive an aerosol-generating substrate; a heating element configured to heat the aerosol-generating substrate; a power source operatively connected to the heating element; a controller configured to control the power source and the heating element; and a switch comprising a sensor to detect presence of an actuator. The switch is operatively connected to the controller. A method for using the aerosol-generating device includes placing the actuator adjacent the sensor and detecting the presence of the actuator; and controlling power supply to the heating element.

First claim

The invention claimed is:

1. An aerosol-generating device comprising:
a body comprising a cartridge receptacle configured to receive a cartridge with an aerosol-generating substrate, and a heating element configured to heat the aerosol-generating substrate;
a power source operatively connected to the heating element;
a controller configured to control the power source and the heating element;
a switch comprising a sensor to detect presence of an actuator, the switch operatively connected to the controller; and
a mouthpiece handle removably coupled with the body, wherein the mouthpiece handle forms the actuator,
wherein the controller is configured to establish a stand-by mode of the heating element when the presence of the actuator is detected, and wherein the controller is configured to establish an aerosol-generating mode of the heating element when absence of the actuator is detected.

2. The aerosol-generating device according to claim 1 , wherein the switch comprises a magnetic switch.

3. The aerosol-generating device according to claim 2 , wherein the switch comprises a magnetic docking station configured to accept the actuator.

4. The aerosol-generating device according to claim 1 , wherein the heating element comprises one or both of:
a first heating element component comprising a resistive heating component; and
a second heating element component comprising an inductive heating component.

5. The aerosol-generating device according to claim 1 , further comprising a capacitor operatively connected to the heating element.

6. A method for using an aerosol-generating device, the device comprising:
a body comprising a cartridge receptacle configured to receive a cartridge with an aerosol-generating substrate, and a heating element configured to heat the aerosol-generating substrate;
a power source operatively connected to the heating element;
a controller configured to control the power source and the heating element;
a switch comprising a sensor to detect presence of an actuator, the switch being operatively connected to the controller; and
a mouthpiece handle removably coupled with the body, wherein the mouthpiece handle forms the actuator,
wherein the controller is configured to establish a stand-by mode of the heating element when the presence of the actuator is detected, and wherein the controller is configured to establish an aerosol-generating mode of the heating element when absence of the actuator is detected;
the method comprising:
placing the actuator adjacent the sensor and detecting the presence of the actuator; and
controlling power supply to the heating element.

7. The method according to claim 6 , further comprising:
removing the actuator and detecting the absence of the actuator; and
establishing an aerosol-generating mode of the heating element.

8. The method according to claim 6 , wherein the switch comprises a magnetic switch.

9. The method according to claim 8 , wherein the switch comprises a magnetic docking station configured to accept the actuator and wherein placing the actuator adjacent the sensor comprises docking the actuator at the magnetic docking station.

10. The method according to claim 6 , the method further comprising establishing a stand-by mode of the heating element, wherein in the stand-by mode, the heating element heats an aerosol-generating substrate received in the body to a first temperature.

11. The method according to claim 6 , wherein in the aerosol-generating mode, the heating element heats an aerosol-generating substrate received in the body to a second temperature.

12. The method of claim 10 , wherein the first temperature is 100° C. or greater.

13. The method of claim 10 , wherein the first temperature is 200° C. or lower.

14. The method of claim 11 , wherein the second temperature is 160° C. or greater.

15. The method of claim 11 , wherein the second temperature is 260° C. or lower.

16. The aerosol-generating device according to claim 1 further comprising a vessel configured to contain liquid and to have a headspace above the liquid, wherein the vessel comprises a headspace outlet, and wherein the mouthpiece handle is coupled to a hose attached to the headspace outlet.

17. The aerosol-generating device according to claim 1 , wherein the mouthpiece handle comprises one or more magnets.
