Abrégé

The invention is a vapourising device (10) for vapourising a volatile liquid for supply to an environment. The device has a housing 100 having an inlet (109) for receiving inlet air which is warmed by inlet heater (111) before being supplied to cartridge assembly (200). Cartridge assembly (200) has a reservoir (204) for containing the liquid to be vapourised and at least one wick (206), one end of which is located in the reservoir to receive and transport the liquid to the other, exposed end of the wick where the liquid evaporates and mixes with the supplied stream of heated inlet air. The wick may be heated by a wick heater (211). The device also includes an outlet duct section (217) between the wick (206) and the outlet (221) which is conical in shape and is configured to accelerate the flow of the mixture of inlet air and vapourised liquid away from the wick towards the outlet (221). The invention provides increased control of the vapourisation process and helps to reduce condensation of the volatile liquid back onto the apparatus or onto surrounding surfaces.
