An aerosol generating device comprising: an elongated body (1) having a proximal mouth end (4), a distal end (5) and an inner duct (35) extending longitudinally to the mouth end, a coupling (3) to be releasably coupled to the body, a pressurized cartridge (2) containing fluid having an inwardly depressable axial discharge tube (17) to open a valve (18) therein to release the fluid through of the discharge tube, the cartridge and the duct having a common longitudinal axis, and a trigger (7) mounted on the body to perform a reciprocal movement along a trigger axis extending transversely from the longitudinal axis, having the trigger a manually depressable surface part (36) that faces outward from the body, and a cam action surface part (39a) that functions in the depression of the manually depressable surface part towards the inter ior of the body along the trigger shaft, pressing the discharge tube into the cartridge and operating the valve in order to release the fluid from the cartridge through the discharge tube and through the body to the end of the mouth, and characterized by a tubular nozzle member (12) slidably mounted in the body, the nozzle member having an end to abut the cartridge tube and a trigger coupling end that engages with the part of the cam action surface of the trigger so that said depression of the trigger inwards drives the nozzle member toward the distal end of the body member to drive the discharge tube into the cartridge by operating the valve and releasing the fluid to through the discharge tube.Un dispositivo generador de aerosol que comprende: un cuerpo (1) alargado que tiene un extremo (4) proximal para boca, un extremo (5) distal y un conducto (35) interior que se extiende longitudinalmente hasta el extremo de la boca, un acoplamiento (3) para acoplarse de forma liberable al cuerpo, un cartucho (2) presurizado que contiene fluido que tiene un tubo (17) de descarga axial depresible hacia el interior para abrir una válvula (18) en él para
