Claims:

1 . A smoking substitute device (10), comprising

a main body (16);

a cavity (14); and

a heating element (12);

wherein the cavity (14) is arranged in the main body (16);

wherein the heating element (12) is arranged in the interior of the cavity (14);

wherein the smoking substitute device (10) is adapted for receiving a smoking substitute consumable (20);

wherein the heating element (12) is adapted for heating the smoking substitute consumable (20); and

wherein the smoking substitute device (10) comprises a shroud (38) at least partially surrounding the cavity (14) and thermally insulating the heating element (14).

2. A smoking substitute device (10) according to the preceding claim,

wherein the heating element (12) is arranged as a heater rod disposed with the main body (16); and wherein the shroud (38) encloses at least a portion of the heater rod so as to thermally insulate the heater rod.

3. A smoking substitute device (10) according to at least one of the preceding claims,

wherein the cavity (14) is adapted for receiving the smoking substitute consumable (20); and wherein the shroud (38) is at least partially surrounding at least a part of the received smoking substitute consumable (20).

4. A smoking substitute device (10) according to at least one of the preceding claims,

wherein the heating element (12) is adapted for penetrating the outer surface of the smoking substitute consumable (20) to get into contact with tobacco material located inside the smoking substitute consumable (20) upon insertion of the smoking substitute consumable (20) into the smoking substitute device (10), for heating of the tobacco material.

5. A smoking substitute device (10) according to at least one of the preceding claims,

wherein the shroud (38) is thermally insulating the interior of the isolative shroud (38) from the exterior of the isolative shroud (38).

6. A smoking substitute device (10) according to at least one of the preceding claims,

wherein the shroud (38) is made of a polymer material, in particular made of polyether ether ketone (PEEK).

7. A smoking substitute device (10) according to at least one of the preceding claims,

wherein the interior of the shroud (38) is coated with a thermally reflective coating for reflection of thermal energy towards the smoking substitute consumable (20).

8. A smoking substitute device (10) according to at least one of the preceding claims, further comprising

a second heating element,

wherein the second heating element is arranged between the smoking substitute consumable (20) and the shroud (38) for heating at least a part of the outer surface of the smoking substitute consumable (20).

9. A smoking substitute device (10) according to at least one of the preceding claims,

wherein the heating element (12) is a rod-shaped heating element; and

wherein the length of the isolative shroud (38) is at least the length of the rod-shaped heating element.

10. A smoking substitute device (10) according to at least one of the preceding claims,

wherein the shroud (38) comprises an aperture (40) for allowing access to the interior of the cavity (14), in particular wherein the aperture (40) is located distal from an outward facing opening (40) of the cavity (14).

1 1 . A smoking substitute device (10) according to at least one of claims 9 and 10,

wherein the aperture (40) is arranged in size such that a user of the smoking substitute device (10) in unable to come into bodily contact with the heating element (12), in particular wherein the aperture (40) on the shroud is sized to prevent finger access.

12. A smoking substitute device (10) according to at least one of the preceding claims,

wherein the smoking substitute device (10) is a heat-not-burn smoking substitute device (10).

13. A smoking substitute system, comprising a smoking substitute device (10) according to at least one of the preceding claims and a smoking substitute consumable (20).

14. A method of using the smoking substitute system according to the preceding claim, the method comprising:

inserting the smoking substitute consumable (20) into the smoking substitute device (10); and heating the smoking substitute consumable (20) using the heating element (12).

15. A method according to the preceding claim, the method further comprising:

inserting the smoking substitute consumable (20) into the cavity (14) within the main body (16) of the smoking substitute device (10); and

penetrating the smoking substitute consumable (20) with the heating element (12) upon insertion of the smoking substitute consumable (20).
