Aerosol-generating device

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.

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.   
     
     
         2 . 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.   
     
     
         3 . 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.   
     
     
         4 . 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. 
     
     
         5 . 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.   
     
     
         6 . 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. 
     
     
         7 . 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. 
     
     
         8 . 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.   
     
     
         9 . 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. 
     
     
         10 . 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. 
     
     
         11 . The aerosol-generating device according to  claim 1 , wherein the shielding unit is made of a material that blocks transmission of electromagnetic waves.
