## Abstract

An aerosol-generating device is disclosed. The aerosol-generating device of the present disclosure includes a body; a cartridge configured to be coupled to the body and comprising: a first container portion having an inner wall defining an elongated insertion space and a chamber formed between an outer wall and the inner wall configured to store a liquid therein, a second container portion adjacent to the first container portion, a wick mounted in the second container portion to be in communication with the chamber, and a heater configured to heat the wick; a sensor disposed adjacent to the cartridge, wherein the sensor is configured to sense electromagnetic properties around; and a shielding unit configured to shield the sensor from external interference.

## Claims

### Claim 1

An aerosol-generating device comprising:
a body;
a cartridge configured to be coupled to the body and comprising:
a first container portion having an inner wall defining an elongated insertion space and a chamber formed between an outer wall and the inner wall configured to store a liquid therein,
a second container portion adjacent to the first container portion,
a wick mounted in the second container portion to be in communication with the chamber, and
a heater configured to heat the wick;
a sensor disposed adjacent to the cartridge, wherein the sensor is configured to sense electromagnetic properties around; and
a shielding unit configured to shield the sensor from external interference.

### Claim 2 (depends on 1)

The aerosol-generating device according to claim 1, wherein the body comprises:
a lower body; and
an upper body disposed on the lower body and positioned adjacent to the cartridge,
wherein the sensor is disposed at the upper body.

### Claim 3 (depends on 2)

The aerosol-generating device according to claim 2, wherein the upper body comprises:
a first side wall facing an outer wall of a side of the cartridge; and
a second side wall disposed opposite the first side wall,
wherein the shielding unit comprises a first part disposed at the second side wall to cover a side portion of the sensor.

### Claim 4 (depends on 2)

The aerosol-generating device according to claim 2, wherein the shielding unit comprises a second part disposed at an upper wall of the upper body to cover an upper portion of the sensor.

### Claim 5 (depends on 2)

The aerosol-generating device according to claim 2, wherein the body comprises an insertion wall disposed on the lower body to surround at least a portion of the second container portion,
wherein the sensor faces the first container portion, and
wherein the shielding unit comprises a third part disposed at the insertion wall.

### Claim 6 (depends on 2)

The aerosol-generating device according to claim 2, wherein the shielding unit comprises a fourth part disposed between the lower body and the upper body.

### Claim 7 (depends on 6)

The aerosol-generating device according to claim 6, wherein the fourth part covers a lower portion of the cartridge and a lower portion of the sensor.

### Claim 8 (depends on 1)

The aerosol-generating device according to claim 1, further comprising:
a cap configured to cover at least a portion of the body and the cartridge, the cap having an opening corresponding to the insertion space,
wherein the shielding unit is disposed at at least a portion of the cap.

### Claim 9 (depends on 8)

The aerosol-generating device according to claim 8, wherein the shielding unit comprises a fifth part disposed at a side wall of the cap to cover a side portion of the sensor.

### Claim 10 (depends on 8)

The aerosol-generating device according to claim 8, wherein the shielding unit comprises a sixth part disposed at an upper wall of the cap to cover an upper portion of the sensor.

### Claim 11 (depends on 1)

The aerosol-generating device according to claim 1, wherein the shielding unit is made of a material that blocks transmission of electromagnetic waves.
