Control for 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:
a first housing containing a micro-controller electrically connected to a battery, a memory, at least one sensor, at least one LED, and to a communication unit having an antenna for sending data from the antenna by wireless communication through a network to a second device;
first and second electrical terminals on a first end of the first housing, the first and second terminals electrically connected to the micro-controller;
a second housing connectable to the first housing, the second housing containing a vaporization chamber, a heater inside of the vaporization chamber, an air flow path having a central portion extending centrally through the second housing leading to an outlet in a mouthpiece at a second end of the second housing, and a liquid supply on opposite sides of the central portion of the air flow path;
third and fourth electrical terminals on a first end of the second housing which make electrical contact with the first and second electrical terminals, respectively, when the second housing is attached to the first housing, to establish a power and/or a data connection between them.
2. The electronic smoking device of claim 1 further including a charge/discharge protection circuit electrically connected to the micro-controller.
3. The electronic smoking device of claim 1 wherein the micro-controller detects and uses a resistance of the heater to adjust one or more heating parameters of the heater.
4. The electronic smoking device of claim 1 further including a sound generator in the first housing electrically connected to the micro-controller.
5. The electronic smoking device of claim 1 further including an air inlet in the first housing, the air inlet connecting to the air flow path in the second housing.
6. The electronic smoking device of claim 1 wherein the at least one sensor senses a user's action for smoking.
7. The electronic smoking device of claim 1 wherein the memory stores usage data, the communication unit sends usage data to the second device, and the controller controls the LED to provide a visual indictor of device status.
8. The electronic smoking device of claim 7 wherein the usage data includes amount of liquid remaining in the liquid supply.
9. The electronic smoking device of claim 1 wherein the memory stores user information and the communication unit sends the user information to the second device.
10. An electronic smoking device comprising:
a first housing containing a micro-controller electrically connected to a battery, a memory, at least one sensor for sensing a user's action for smoking, at least one LED, and to a communication unit having an antenna for sending usage data from the antenna by wireless communication through a network to a second device, the micro-controller electrically connected to a charge/discharge protection circuit;
first and second electrical terminals on a first end of the first housing, the first and second terminals electrically connected to the micro-controller;
a second housing connectable to the first housing, the second housing containing a vaporization chamber, a heater inside of the vaporization chamber, an air flow path having a central portion extending centrally through the second housing leading to an outlet in a mouthpiece at a second end of the second housing, and a liquid supply on opposite sides of the central portion of the air flow path;
third and fourth electrical terminals on a first end of the second housing which make electrical contact with the first and second electrical terminals, respectively, when the second housing is attached to the first housing, to establish a power and/or a data connection between them;
the usage data including an amount of liquid remaining in the liquid supply, the memory storing usage data, the communication unit sending usage data to the second device, the controller controlling the LED to provide a visual indictor of device status, and the micro-controller detecting and using a resistance of the heater to adjust one or more heating parameters of the heater.
