Abstract

Claims (32)

1. An aerosol generating device comprising:

a cartomizer comprising:

a cartridge configured to store an aerosol generating material; and

an atomizer configured to vaporize the aerosol generating material;

an accommodation space accommodating the cartomizer,

at least one pair of electrodes arranged in positions contacting one side of the cartridge, the electrodes are arranged on an inner surface of the accommodation space;

at least one pair of bottom electrodes arranged on a bottom surface of the cartridge;

a sensor configured to measure capacitance of the electrodes and the bottom electrodes; and

a controller configured to:

detect the remaining amount of the aerosol generating material based on the capacitance of the electrodes; and

correct the detected remaining amount of the aerosol generating material according to a tilt of the cartridge detected based on the capacitance of the bottom electrodes.

2. The aerosol generating device of claim 1 , further comprising:

a battery configured to supply power to the atomizer,

wherein the controller is further configured to control the power supplied to the atomizer, based on the detected remaining amount of the aerosol generating material.

3. The aerosol generating device of claim 1 wherein the one side indicates a side of the cartridge contacting an inner surface of an accommodation space included in the aerosol generating device to accommodate the cartomizer.

4. The aerosol generating device of claim 1 , wherein the cartomizer is detachable from the aerosol generating device.

5. The aerosol generating device of claim 1 , wherein the electrodes have elongated shapes extending in a first direction of the one side and are arranged in a second direction of the one side,

wherein the first direction and the second direction are orthogonal to each other.

6. The aerosol generating device of claim 1 , wherein in the electrodes, distances between the two electrodes of each pair are different from each other.

7. The aerosol generating device of claim 1 , wherein the electrodes comprise n pairs formed of 2n electrodes, and wherein n is a natural number.

8. The aerosol generating device of claim 1 , wherein the sensor comprises at least one channel having a number corresponding to a number of the at least one pair.

9. The aerosol generating device of claim 1 , wherein the atomizer comprises:

a wick transferring the aerosol generating material outside the cartridge; and

a coil heating the aerosol generating material transferred by the wick.

10. An aerosol generating method performed by an aerosol generating device, the method comprising:

measuring capacitance of at least one pair of electrodes arranged in positions contacting one side of a cartridge storing an aerosol generating material;

measuring the capacitance of at least one pair of bottom electrodes arranged on the bottom surface of the cartridge;

detecting a remaining amount of the aerosol generating material based on the capacitance;

correcting the detected remaining amount of aerosol generating material according to a tilt of the cartridge based on the capacitance of the bottom electrodes; and

controlling, power supplied to an atomizer vaporizing the aerosol generating material based on the detected remaining amount of the aerosol generating material,

wherein the aerosol generating device comprises a cartomizer comprising the cartridge and the atomizer, and an accommodation space accommodating the cartomizer, and

wherein the electrodes are arranged on an inner surface of the accommodation space.
