Abstract

An aerosol-generating device according to an embodiment includes: a heater including a heating element for heating an aerosol-generating material; and a controller including a first port electrically connected to the heater, and configured to control operation of the heating element by controlling activation of the first port.

Claims (28)

1. An aerosol-generating device comprising:

a heater including:

a heating element for heating an aerosol-generating material; and

a heater switch connected between a battery and the heating element;

a memory configured to store a program; and

at least one processor including:

an internal switch configured to control activation of a first port; and

the first port electrically connected to the heater,

wherein the at least one processor is communicatively coupled to the memory, and configured to control operation of the heating element by controlling activation of the first port, and

wherein the at least one processor is configured to execute the program to:

determine whether to deactivate the first port; and

based on a determination to deactivate the first port, block an electrical signal from entering and exiting the first port by opening the internal switch and deactivating the first port such that the electrical signal transmitted to the heater switch is removed to reduce a standby current.

2. The aerosol-generating device of claim 1 , wherein the at least one processor is further configured to execute the program to:

cut off power supplied to the heater switch by the first port, based on the determination to deactivate the first port, causing the heater switch to stop a heating operation of the heating element.

3. The aerosol-generating device of claim 1 , wherein the at least one processor is further configured to execute the program to:

activate the first port to supply power to the heater switch, based on a determination to activate the first port, causing the heater switch to initiate a heating operation of the heating element.

4. The aerosol-generating device of claim 1 , further comprising a user interface configured to receive a user input,

wherein the controller includes a second port electrically connected to the user interface, and activates the first port based on the user input received through the second port.

5. The aerosol-generating device of claim 4 , wherein the controller switches from a first mode in which the first port is deactivated to a second mode to activate the first port when the user input is received through the second port in the first mode.

6. The aerosol-generating device of claim 1 , further comprising a sensor configured to detect a state of the heating element,

wherein the controller further includes a third port electrically connected to the sensor, and periodically activates and deactivates the third port.

7. The aerosol-generating device of claim 6 , wherein the controller activates the third port for a first time period and deactivates the third port for a second time period.

8. The aerosol-generating device of claim 6 , wherein the controller activates the first port whenever the third port is activated.

9. The aerosol-generating device of claim 6 , wherein the controller outputs an alarm signal when a temperature of the heating element measured through the sensor is greater than or equal to a predetermined temperature.

10. The aerosol-generating device of claim 1 , further comprising a sensor configured to detect a state of the heating element,

wherein the controller further includes a third port electrically connected to the sensor, and periodically switches between a first mode in which the first port is deactivated and a third mode in which the third port is activated.

11. The aerosol-generating device of claim 1 , wherein the at least one processor is further configured to execute the program to:

close the internal switch, based on a determination to activate the first port.
