Abstract

Disclosed is an aerosol generating device (100). The aerosol generating device (100) comprises a first separable section (103) comprising a heating module (104) having a chamber (105) having an opening (106) to receive an aerosol generating article (107), and a second separable section (108) comprising a primary power source (109). Further, a latch arrangement (110) is configured to detachably attach the first separable section (103) to the second separable section (108) along a lateral direction (101) of the aerosol generating device (100). Further, a key (112) insertable in a keyhole (111) causes the latch arrangement (110) to move to detach the first separable section (103) from the second separable section (108), based on the movement of the latch arrangement (110) after insertion of the key (112) in the keyhole (111).
