Abstract

A component of an electronic vapor provision device with a reservoir for storing source liquid, an atomizer for vaporizing source liquid from the reservoir and delivering vapor into an air flow path through the device, and an electrical power supply for providing electrical power to the atomizer comprises an absorbent element to collect source liquid escaped from the reservoir and located so as to be upstream of the atomizer with respect to an air flow direction along the air flow path when the component is assembled into the electronic vapor provision device.

Claims (11)

1. An electronic vapor provision device, the device having a reservoir for storing source liquid, an atomizer for vaporizing source liquid from the reservoir and delivering vapor into an air flow path through the device, and an electrical power supply for providing electrical power to the atomizer, in which the electronic vapor provision device comprises:

an absorbent element to collect source liquid escaped from the reservoir, the absorbent element located so as to be upstream or downstream of the atomizer with respect to an air flow direction along the air flow path, wherein the absorbent element is formed from an absorbent material comprising polyester.

2. An electronic vapor provision device according to claim 1 , in which the absorbent element is located so as to be between the atomizer and the electrical power supply along a liquid flow path from the atomizer to the electrical power supply.

3. An electronic vapor provision device according to claim 1 , in which the absorbent element inhibits said escaped liquid from reaching the electrical power supply.

4. An electronic vapor provision device according to claim 1 , in which the electrical power supply comprises a battery.

5. An electronic vapor provision device according to claim 4 , in which the absorbent element is situated to protect the battery from exposure to the source liquid.

6. An electronic vapor provision device according to claim 1 , in which the electrical power supply comprises control circuitry for controlling the provision of electrical power to the atomizer.

7. An electronic vapor provision device according to claim 6 , in which the absorbent element is situated to protect the control circuitry from exposure to the source liquid.

8. An electronic vapor provision device according to claim 1 , in which the absorbent element has a planar shape.

9. An electronic vapor provision device according to claim 1 , and further comprising a further absorbent element, the further absorbent element located to as to be downstream of the atomizer with respect to the air flow direction along the air flow path.

10. An electronic vapor provision device according to claim 1 , in which the electronic vapor provision device is a unitary device that cannot be separated into two parts.
