Electronic smoking device

An electronic smoking device comprising:

• a first sensor for detecting a user's action for smoking;
• an air inlet;
• an air flow path extending from the air inlet;
• a liquid compartment storing a smoking liquid;
• a vaporizing compartment connected to the liquid compartment and to the air flow path;
• a dispensing control device covering both the air flow path and an opening in the liquid compartment, wherein the dispensing control device is configured to passively dispense the smoking liquid from the liquid compartment;
• a heater located at the vaporizing compartment;
• a controller configured to activate the heater to vaporize the smoking liquid dispensed from the liquid compartment when the user's action for smoking is detected by the first sensor;
• and
• a smoke outlet connected to the vaporizing compartment,
• wherein the dispensing control device is configured to dispense an amount of the smoking liquid in response to air flow generated by the user flowing through the dispensing control device and into the vaporizing compartment.

An electronic smoking device comprising:

• a first sensor for detecting a user's action for smoking;
• an air inlet;
• an air flow path extending from the air inlet;
• a liquid compartment storing a smoking liquid;
• a vaporizing compartment connected to the air flow path;
• a passive micro liquid screen covering both the air flow path and an opening in the liquid compartment for delivering the smoking liquid, wherein the passive micro liquid screen is configured to selectively dispense the smoking liquid from the liquid compartment to the vaporizing compartment in response to air flowing therethrough;
• a heater located at the vaporizing compartment;
• a controller configured to activate the heater to vaporize the smoking liquid dispensed from the liquid compartment when the user's action for smoking is detected by the first sensor;
• and
• a smoke outlet connected to the vaporizing compartment;
• wherein the passive micro liquid screen comprises a micro aperture pattern, wherein the smoking liquid is dispensed through the micro aperture pattern when air flowing from the air inlet through the vaporizing compartment in response to the user's action for smoking breaks surface tension of the smoking liquid formed at the micro aperture pattern.
