Claims

1. A component of an electronic vapour provision device, the device having a reservoir for storing source liquid, an atomiser for vaporising source liquid from the reservoir and delivering vapour into an air flow path through the device, and an electrical power supply for providing electrical power to the atomiser, in which the component comprises:

an absorbent element to collect source liquid escaped from the reservoir, the absorbent element located so as to be upstream of the atomiser with respect to an air flow direction along the air flow path when the component is assembled into the electronic vapour provision device.

2. A component according to claim 1 , in which the absorbent element is located so as to be between the atomiser and the electrical power supply in the assembled electronic vapour provision device along a liquid flow path from the atomiser to the electrical power supply.

3. A component according to claim 1 or claim 2, in which the absorbent element inhibits said escaped liquid from leaving the component.

4. A component according to any preceding claim, in which the absorbent element inhibits said escaped liquid from reaching the electrical power supply.

5. A component according to any preceding claim, in which the electrical power supply comprises a battery.

6. A component according to any preceding claim, in which the electrical power supply comprises control circuitry for controlling the provision of electrical power to the atomiser.

7. A component according to any preceding claim, in which the absorbent element is located adjacent to an end face of the component.

8. A component according to claim 7, in which the end face of the component is at an end of the component connectable to another component of the electronic vapour provision device.

9. A component according to any one of claims 1 to 8, in which the component is a cartomiser component housing the reservoir and the atomiser and is connectable to a power component housing the electrical power supply, and the absorbent element is located so as to inhibit said escaped liquid from leaving the cartomiser component, and also from reaching the electrical power supply when the cartomiser component is connected to the power component.

10. A component according to claim 9, in which the absorbent element is mounted within an end cap of the cartomiser component which is configured to allow electrical contact with an electrical power supply housed in a power component of the electronic vapour provision device to which the said component is connectable.

1 1. A component according to any one of claims 1 to 8, in which the component is a power component housing the electrical power supply and connectable to a cartomiser component housing the reservoir and atomiser, and the absorbent element is located so as to inhibit said escaped liquid from reaching the electrical power supply when the power component is connected to the cartomiser component.

12. A component according to any preceding claim, in which the absorbent element has a planar shape and a thickness orthogonal to its plane in the range of 1 mm to 10 mm.

13. A component according to any preceding claim in which the absorbent element is formed from an absorbent material comprising polypropylene and polyethylene.

14. A component according to claim 13, in which the absorbent material comprises 50% polypropylene and 50% polyethylene, or polypropylene in the range of 45% to 55% and polyethylene in the range of 55% to 45%, or polypropylene in the range of 48% to 52% and polyethylene in the range of 52% to 48%, or polypropylene in the range of 49% to 51 % and polyethylene in the range of 51 % to 48%.

15. A component according to any preceding claim, in which the absorbent element is formed from an absorbent material which increases its volume by not more than 1 %, 3%, 5%, 10% or 20% when fully saturated.

16. An electronic vapour provision device comprising a component according to any preceding claim.

17. An electronic vapour provision device according to claim 16, in which the component is separably connectable to another component of the electronic vapour provision device.

18. An electronic vapour provision device according to claim 16 in which the component is a permanent component of the electronic vapour provision device.
