Abstract
A device for emanating a liquid wherein the device is for use with a refill of liquid, wherein the device comprises: a housing with at least one exit port for emanated liquid therein; a hollow and elongate extraction limb having at least one aperture therein to define a fluid flow path from the said at least one aperture into the hollow extraction limb and to said at least one exit port; a heater that, in use, can transfer heat therefrom to at least a part of the extraction limb.
Claims14
A device for emanating a liquid wherein the device is for use with a refill of liquid, wherein the device comprises:
- a housing with at least one exit port for emanated liquid therein;
- a hollow and elongate extraction limb having at least one aperture therein to define a fluid flow path from the said at least one aperture into the hollow extraction limb and to said at least one exit port;
- a heater that, in use, transfers heat therefrom to at least a part of the extraction limb.
A system for emanating a liquid comprising a device and a refill of liquid, wherein
- the device comprises:
- a housing with at least one exit port for emanated liquid therein;
- a hollow and elongate extraction limb having at least one aperture therein to define a fluid flow path from the said at least one aperture into the hollow extraction limb and to said at least one exit port;
- a heater that, in use, transfers heat therefrom to at least a part of the extraction limb;
- and wherein the refill comprises:
- a refill housing;
- at least one reservoir in the refill housing for holding the liquid, wherein the liquid contains one or more active materials;
- at least one aperture in the refill housing sealed by at least one valve wherein said at least one valve defines a liquid pathway from the reservoir to the exterior of the refill, wherein at least one of said valve(s) is configured to be automatically resealable when not being held open;
- and at least one wick housed entirely within the refill housing.
