Aerosol generating device

Abstract

An aerosol generating device comprising a heater housing and a consumable engagement component (102) located within the heater housing. The consumable engagement component comprises an inner wall (106) defining a receiving cavity (108). The receiving cavity is configured to house a heater and engage with a consumable, the consumable including an aerosol generating substrate for heating by the heater. The consumable engagement component further comprises an outer wall (114) located between the inner wall and the heater housing, the outer wall defining an insulating cavity (1116). The insulating cavity is located between the receiving cavity and the heater housing to provide thermal insulation between the receiving cavity and the heater housing. The inner wall and the outer wall are integrally formed from the same material.

1 . An aerosol generating device comprising:
 a heater housing; and,   a consumable engagement component located within the heater housing, the consumable engagement component comprising:
 an inner wall defining a receiving cavity, the receiving cavity configured to house a heater and engage with a consumable, the consumable including an aerosol generating substrate for heating by the heater; and 
 an outer wall located between the inner wall and the heater housing, the outer wall defining an insulating cavity, the insulating cavity located between the receiving cavity and the heater housing to provide thermal insulation between the receiving cavity and the heater housing, 
 wherein the inner wall and the outer wall are integrally formed from the same material, and wherein the inner wall is tapered and the outer wall is tapered. 
   
     
     
         2 . The device of  claim 1  wherein the consumable engagement component further comprises an insulation opening into the insulating cavity, the insulation opening connecting the insulating cavity to the ambient atmosphere. 
     
     
         3 . The device of  claim 2  wherein insulating cavity and the receiving cavity open towards opposite directions 
     
     
         4 . The device of  claim 2 , wherein the insulating cavity is tapered. 
     
     
         5 . The device of  claim 2  wherein the receiving cavity and the insulating cavity are longitudinally elongate along the same direction. 
     
     
         6 . The device of  claim 1  wherein the consumable engagement and the heater housing comprise respective complementary interlocking elements 
     
     
         7 . The device of  claim 1  wherein the consumable engagement component is integrally formed form the same material. 
     
     
         8 . The device of  claim 1  further comprising a heater. 
     
     
         9 . The device of  claim 8  wherein the heater extends from a body of the device to protrude into the receiving cavity. 
     
     
         10 . The device of  claim 9  wherein the depth of the insulating cavity is approximately equal to the length of the portion of the heater which protrudes into the receiving cavity when the heater is housed within the receiving cavity. 
     
     
         11 . The device of  claim 1  wherein the heater housing is the housing of a cap of the device. 
     
     
         12 . The device of  claim 1  wherein the cap is movably coupled to a body of the device. 
     
     
         13 . The device of  claim 1  wherein the inner wall and the outer wall are integrally formed from polyetheretherketone (PEEK). 
     
     
         14 . A consumable engagement component for use in an aerosol generating device, the consumable engagement component comprising:
 an inner wall defining a receiving cavity, the receiving cavity configured to house a heater and engage with a consumable, the consumable including an aerosol generating substrate for heating with the heater; and   an outer wall located adjacent the inner wall externally to the receiving cavity, the outer wall defining an insulating cavity, the insulating cavity located between the inner wall and the outer wall to provide thermal insulation to an external surface of the inner wall,   wherein the inner wall and the outer wall are integrally formed from the same material, wherein the inner wall is tapered and the outer wall is tapered.   
     
     
         15 . An aerosol generating apparatus comprising the aerosol generating device of  claim 1  and a consumable, the consumable including an aerosol forming substrate for heating with a heater, and the consumable insertable into the receiving cavity of the consumable engagement component.
