## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

A device according to claim 1, wherein the extraction limb is made from a heat-conductive material.

### Claim 3 (depends on 1)

A device according to claim 1, wherein the heater is fixed in contact with the extraction limb to allow heat emitted from the heater to pass via conduction into the extraction limb.

### Claim 4 (depends on 1)

A device according to claim 1, wherein the heater extends within the extraction limb to define a substantially central core within the limb wherein the fluid flow path within the hollow limb is defined from the at least one aperture to the at least one exit port by travelling between an outer surface of the heater and an inner surface of the extraction limb.

### Claim 5 (depends on 1)

A device according to claim 1, wherein the heater extends into the extraction limb to at least 25% of the limb's length.

### Claim 6 (depends on 1)

A device according to claim 1, wherein the extraction limb, in use, is inserted within a refill of liquid and configured to emit sufficient heat within the refill to volatilise the liquid and cause said volatilised liquid to enter the at least one aperture and along the fluid pathway to the at least one exit port and into the device's surrounding environment.

### Claim 7 (depends on 1)

A device according to claim 1, wherein the heater is configured to impart enough heat to volatilise the liquid but not enough heat to boil the liquid.

### Claim 8 (depends on 1)

A device according to claim 1, wherein the extraction limb is substantially cylindrical.

### Claim 9 (depends on 1)

A device according to claim 1, wherein a plurality of apertures are provided in the extraction limb.

### Claim 10 (depends on 9)

A device according to claim 9, wherein and the apertures are provided in side walls of the limb.

### Claim 11 (depends on 1)

The refill of liquid for use with the device according to claim 1, 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.

### Claim 12

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.

### Claim 13

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 refill of liquid.

### Claim 14

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, can transfer heat therefrom to at least a part of the refill of liquid;
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.
