Dosing control for an electronic smoking device
The present disclosure relates to systems and methods for controlling dosing of an electronic smoking device. An electronic smoking device comprises a body through which a flow path at least partially extends, an air inlet in the body that is fluidly connected to the flow path, a liquid compartment for storing a liquid within the body, a vaporizer positioned in the body and configured to receive liquid from the liquid compartment and air from the flow path to generate vaporized liquid, an outlet in the body configured to receive vaporized liquid from the vaporizer, and circuitry connected to the vaporizer and configured to control dosage of vaporized liquid. A method for controlling dosage in an electronic smoking device comprises sensing an airflow, releasing a liquid into the airflow, activating a vaporizer to generate vaporized liquid, and controlling flow of airflow, liquid or vaporized liquid to control dosage.

5. The electronic smoking device of claim 1 , wherein the controller circuitry is configured and arranged to control the dosage by dispensing a predetermined amount of liquid per user action.
6. The electronic smoking device of claim 5 wherein the predetermined amount of liquid is consistently dispensed as the same amount.
7. The electronic smoking device of claim 1 , wherein the controller circuitry is further configured and arranged to control the dosage by varying the amount of liquid mixed with air before vaporization.
8. The electronic smoking device of claim 7 , wherein the controller circuitry is configured and arranged to control a dispensing device and thereby control liquid flow from the liquid compartment to the vaporizer.
9. The electronic smoking device of claim 1 , wherein the controller circuitry is configured and arranged to control the dosage by varying the amount of vaporized liquid in the air.
10. The electronic smoking device of claim 9 , wherein the amount of vaporized liquid in the air is controlled by activation of the vaporizer.
11. The electronic smoking device of claim 1 , wherein the controller circuitry is further configured to transmit a disabling signal to an airflow sensor, and the airflow sensor is further configured, in response to a disabling signal from the controller circuitry, to stop airflow through the flow path.
12. The electronic smoking device of claim 1 , further including a sensor integrated with the controller circuitry, and configured and arranged to detect a user action and activate the vaporizer when a user action is detected.
13. The electronic smoking device of claim 12 , further including an active dispensing device configured to control flow from the liquid compartment, wherein the sensor is configured to activate the active dispensing device when a user action is detected.
14. The electronic smoking device of claim 13 , wherein the active dispensing device is configured to dispense a predetermined amount of liquid.
15. The electronic smoking device of claim 14 , wherein the active dispensing device is configured to consistently dispense the same amount of liquid each time activated.
16. The electronic smoking device of claim 1 , wherein the controller circuitry is configured and arranged to determine a limit for dosage per unit time that may be delivered.
17. The electronic smoking device of claim 16 , further including a sensor configured to detect a user action, wherein the controller circuitry is responsive to time that the sensor is activated in order to control the vaporizer.
18. The electronic smoking device of claim 17 , further including memory connected to the controller circuitry, wherein the memory includes a time limit for which the vaporizer can be activated.
19. The electronic smoking device of claim 18 , wherein the time limit corresponds to a total time that the vaporizer can be activated for a life of the electronic smoking device.
20. The electronic smoking device of claim 1 , further including a vaporizing compartment connected to the liquid compartment and the flow path, wherein the vaporizer is disposed in the vaporizing compartment and the outlet is fluidly coupled to the vaporizing compartment.
21. An electronic smoking device comprising the following:
a body through which a flow path at least partially extends;
an air inlet in the body that is fluidly connected to the flow path;
a liquid compartment for storing a liquid within the body;
a vaporizer positioned in the body and configured to receive liquid from the liquid compartment and air from the flow path to generate vaporized liquid;
an outlet in the body configured to receive vaporized liquid from the vaporizer;
a sensor configured to detect a user action; and
memory communicatively coupled to the controller circuitry, wherein the memory includes a total time limit for which the vaporizer can be activated for a life of the electronic smoking device;
controller circuitry communicatively coupled to the vaporizer, the sensor, and the memory, the controller circuitry configured and arranged to control dosage of vaporized liquid by disabling the vaporizer when the total time limit retrieved from the memory is equal to or less than a cumulative time that the sensor has been activated.
