Aerosol-generating device

Abstract

An aerosol-generating device is disclosed. The aerosol-generating device of the disclosure includes an upper body havin gan insertion space defined therein; a heater configured to heat the insertion space; and a seal coupled to the upper body, wherein the seal is elastic and has a portion in contact with the upper body, and wherein the portion of the seal in contact with the upper body and the upper body are integrally formed with each other and have a boundary therebetween.

1 . An aerosol-generating device comprising:
 an upper body having an insertion space defined therein;   a heater configured to heat the insertion space; and   a seal coupled to the upper body,   wherein the seal is elastic and has a portion in contact with the upper body, and   wherein the portion of the seal in contact with the upper body and the upper body are integrally formed with each other and have a boundary therebetween.   
     
     
         2 . The aerosol-generating device according to  claim 1 , wherein the portion of the seal is fused to the upper body. 
     
     
         3 . The aerosol-generating device according to  claim 2 , wherein the seal is formed on the upper body through injection molding. 
     
     
         4 . The aerosol-generating device according to  claim 2 , wherein the upper body comprises a plastic material, and
 wherein the seal comprises a rubber material.   
     
     
         5 . The aerosol-generating device according to  claim 1 , further comprising:
 a lower body coupled to a lower portion of the upper body.   
     
     
         6 . The aerosol-generating device according to  claim 5 , wherein an inner circumferential surface of an upper portion of the lower body surrounds an outer circumferential surface of the lower portion of the upper body, and
 wherein the seal comprises a sealing ring configured to seal a gap between the outer circumferential surface of the lower portion of the upper body and the inner circumferential surface of the upper portion of the lower body.   
     
     
         7 . The aerosol-generating device according to  claim 5 , wherein the seal comprises a lower seal in close contact with a lower surface of the upper body to seal a gap between the upper body and the lower body. 
     
     
         8 . The aerosol-generating device according to  claim 7 , further comprising:
 a lead wire extending from the heater to an interior of the lower body,   wherein the lower seal has a connector hole configured such that the lower seal is open to allow the lead wire to pass therethrough.   
     
     
         9 . The aerosol-generating device according to  claim 1 , further comprising:
 a cartridge coupled to a side of the upper body and having a cartridge inlet at an upper portion of the cartridge;   an extension portion extending from an upper portion of the side of the upper body to cover the upper portion of the cartridge, the extension portion having a sensing hole adjacent to the cartridge inlet; and   a sensor disposed adjacent to the sensing hole and configured to detect a flow of air near the sensing hole,   wherein the seal comprises an upper seal surrounding the sensor near the sensing hole and integrally formed with the extension portion.
