Disabling control for an electronic smoking device
The present disclosure relates to systems and methods for controlling disabling of an electronic smoking device. An electronic smoking device includes 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. In one embodiment, the circuitry is configured to shut off the electronic smoking device based on activation time of the vaporizer. In another embodiment, the circuitry is configured to shut off the electronic smoking device after a determined amount of usage has occurred.
1. An electronic smoking device comprising the following:
a housing including a flow path;
a liquid compartment configured for storing a liquid within the housing;
a vaporizer positioned in the flow path and configured to receive liquid from the liquid compartment;
an airflow sensor positioned within the flow path and configured for determining periodic vaporizer activation time by detecting a flow of air through the flow path; and
circuitry communicatively connected to the vaporizer and the airflow sensor, the circuitry configured to
transmit a disabling signal to the airflow sensor after the periodic vaporizer activation time exceeds a predetermined limit;
wherein the airflow sensor is further configured, in response to the disabling signal, to stop the flow of air through the flow path.
2. The electronic smoking device of claim 1 , wherein the circuitry is further configured to permanently disable the electronic smoking device if the determined amount of periodic vaporizer activation time exceeds the predetermined limit stored in the circuitry.
3. The electronic smoking device of claim 1 , wherein the circuitry is further configured to shut off the electronic smoking device by ceasing power delivery to the vaporizer.
4. An electronic smoking device comprising the following:
a housing including a flow path;
a liquid compartment configured for storing a liquid within the housing;
a vaporizer positioned in the flow path and configured to receive liquid from the liquid compartment;
a sensor configured for determining cumulative vaporizer activation time;
circuitry communicatively coupled to the vaporizer and the sensor, the circuitry configured to transmit a disabling signal to the sensor after the determined cumulative vaporizer activation time exceeds a predetermined limit;
wherein the sensor is further configured, in response to the disabling signal, to limit the flow of air through the flow path.
5. An electronic smoking device comprising the following:
a housing including a flow path;
a liquid compartment within the housing and configured for storing a liquid;
a vaporizer positioned in the flow path and configured to receive liquid from the liquid compartment and generate vaporized liquid;
a sensor positioned in the flow path and configured for determining usage;
circuitry communicatively coupled to both the vaporizer and the sensor, the circuitry configured to transmit a signal to the sensor when the determined usage exceeds a predetermined limit stored in the circuitry;
wherein the sensor is further configured, in response to the signal, to control airflow to limit dosage of the vaporized liquid.
6. The electronic smoking device of claim 1 , wherein the determined periodic vaporizer activation time excludes time between user puffs.
