Aerosol provision device

Abstract

An aerosol provision device for generating an aerosol from aerosol-generating material includes a housing and a heating assembly. The heating assembly includes a heating chamber arranged to receive at least a portion of an article having aerosol generating material, an inductor coil encircling at least part of the heating chamber, and a coil support on which at least a portion of the inductor coil is positioned. The coil support includes a locating feature which engages with the housing to locate the heating assembly in position within the housing.

         2 . The aerosol provision device of  claim 1 , wherein the locating feature projects outwardly from the coil support. 
     
     
         3 . The aerosol provision device of  claim 1 , wherein the housing comprises a receiving feature arranged to engage with the locating feature. 
     
     
         4 . The aerosol provision device of  claim 1 , wherein the receiving feature extends axially in a direction from a first end to a second end of the housing. 
     
     
         5 . The aerosol provision device of  claim 1 , wherein the locating feature comprises a first protrusion and a second protrusion. 
     
     
         6 . The aerosol provision device of  claim 5 , wherein the first protrusion is radially offset from the second protrusion. 
     
     
         7 . The aerosol provision device of  claim 3 , wherein the receiving feature comprises a first receiving element arranged to engage with the first protrusion, and a second receiving element arranged to engage with the second protrusion. 
     
     
         8 . The aerosol provision device of  claim 7 , wherein the housing comprises an axially extending aperture, and wherein the first and second receiving elements are on opposing sides of the axially extending aperture. 
     
     
         9 . The aerosol provision device of  claim 1 , wherein the heating assembly comprises an end support. 
     
     
         10 . The aerosol provision device of  claim 9 , wherein the locating feature comprises a first locating feature, and the end support comprises a second locating feature. 
     
     
         11 . The aerosol provision device of  claim 10 , wherein the receiving feature is arranged to engage with the second locating feature. 
     
     
         12 . The aerosol provision device of  claim 9 , wherein the end support comprises an engagement feature arranged to engage with the housing to restrict axial movement. 
     
     
         13 . The aerosol provision device of  claim 9 , wherein the housing comprises a positioning feature that contacts the end support when the end support is fully inserted into the housing. 
     
     
         14 . An aerosol provision device for generating an aerosol from aerosol-generating material comprising a housing and a heating assembly, the heating assembly comprising:
 a heating chamber arranged to receive at least a portion of an article comprising aerosol generating material;   
       an inductor coil encircling at least part of the heating chamber, and
 a coil support on which at least a portion of the inductor coil is positioned; 
 
       wherein the coil support comprises a locating feature which engages with the housing to locate the heating assembly in position within the housing. 
     
     
         15 . An aerosol provision system comprising the aerosol provision device of  claim 1 ; and an article comprising aerosol-generating material. 
     
     
         16 . A method of manufacturing an aerosol provision device for generating an aerosol from aerosol-generating material, comprising:
 assembling a heating assembly comprising:
 a heating chamber arranged to receive at least a portion of an article comprising aerosol generating material; 
 an inductor coil encircling at least part of the heating chamber, and 
 a coil support on which at least a portion of the inductor coil is positioned; 
   the method comprising:   engaging a locating feature on the coil support with a receiving feature on a housing to locate the coil support and the housing;   and inserting the heating assembly into the housing in an axial direction.   
     
     
         17 . The method of  claim 16 , comprising attaching the coil support to an end support. 
     
     
         18 . The method of  claim 17 , wherein the locating feature is a first locating feature, the method comprising engaging a second locating feature on the end support with the receiving feature on the housing to locate the end support and the housing. 
     
     
         19 . The method of  claim 16 , comprising engaging an engagement feature with the housing to prevent axial movement. 
     
     
         20 . The method of  claim 17 , comprising inserting the heating assembly into the housing until the end support contacts a positioning feature on the housing.
