Abstract

An electronic vapor provision device comprising a power cell and a vaporizer, wherein the vaporizer comprises a heater and a heater support, wherein the heater is one the inside of the heater support.

Claims

1. An electronic vapor provision device comprising:

a liquid store;

a wicking element configured to wick liquid from the liquid store to a heating element for vaporizing the liquid;

an air outlet for vaporized liquid from the heating element; and

a heating element support configured to support the heating element, wherein the heating element is on the inside of the heating element support, and wherein the heating element support is the wicking element,

wherein the heating element support comprises a first support section and a second support section, and wherein the heating element is supported between the first support section and the second support section.

2. The electronic vapor provision device of claim 1, wherein the heating element support is porous.

3. The electronic vapor provision device of claim 2, wherein the heating element support is porous ceramic material.

4. The electronic vapor provision device of claim 1, wherein the heating element is supported by the first support section and the second support section.

5. The electronic vapor provision device of claim 1, wherein the heating element is a heating coil.

6. The electronic vapor provision device of claim 5, wherein the heating coil is the same length as the heating element support.

7. The electronic vapor provision device of claim 5, wherein the heating coil is the same length as the heating element support such that ends of the heating coil are flush with ends of the heating element support.

8. The electronic vapor provision device of claim 5, wherein the heating coil is shorter in length than the heating element support.

9. The electronic vapor provision device of claim 5, wherein the heating coil is longer than the heating element support.

10. The electronic vapor provision device of claim 5, wherein the device is configured such that an axis of the heating coil is substantially parallel to airflow through the device when a user sucks on the device.

11. The electronic vapor provision device of claim 1, wherein the device comprises a mouthpiece and a battery assembly which are detachable.
