Apparatus for heating smokable material

1. Apparatus for heating smokable material to volatilize at least one component of the smokable material, the apparatus having a longitudinal axis and comprising:

a first casing portion comprising a first connector and a recess;

a second casing portion comprising a second connector that is releasably engaged with the first connector; and

a cartridge for receipt in the recess, the cartridge comprises a heating element with smokable material arranged thereon,

wherein the first connector comprises a first surface that faces radially inwardly, towards the longitudinal axis,

wherein the second connector comprises a second surface that faces radially outwardly, away from the longitudinal axis,

wherein, when engaged, the first and second connectors define an inlet between the first and second connectors for admitting air into the recess from an exterior of the apparatus, and

wherein at least a portion of the inlet is defined between the first surface and the second surface.

2. Apparatus according to claim 1 , wherein the second connector is for engagement with the first connector so as to connect the second casing portion to the first casing portion.

3. Apparatus according to claim 2 , wherein the second connector is for releasable engagement with the first connector so as to detachably connect the second casing portion to the first casing portion.

4. Apparatus according to claim 1 , wherein the first and second connectors are relatively movable to alter a cross-sectional area of the inlet, while maintaining engagement of the first and second connectors.

5. Apparatus according to claim 1 , wherein the apparatus is arranged to heat the smokable material to volatilize the at least one component of the smokable material without combusting the smokable material when the cartridge is received in the recess.

6. Apparatus according to claim 1 , wherein at least one of the first casing portion and the second casing portion contains a controller arranged to control heating of the heating element so as to cause heating of the smokable material to volatilize the at least one component of the smokable material without combusting the smokable material when the cartridge is received in the recess.

7. Apparatus according to claim 1 , wherein the first casing portion defines an opening into the recess, the apparatus further comprising:

a mouthpiece comprising an inlet, an outlet, a channel fluidly connecting the inlet with the outlet, and a seal surrounding the inlet;

wherein the mouthpiece is locatable relative to the first casing portion so as to cover the opening, with the seal facing the recess to seal the inlet of the mouthpiece to the cartridge in use.

8. Apparatus according to claim 7 , wherein the mouthpiece is locatable relative to the first casing portion so as to cover the opening with the seal compressed between the channel and the cartridge when the cartridge is received in the recess.

9. Apparatus according to claim 7 , wherein the cartridge comprises a housing defining a chamber, the housing has a volatilized material flow path extending therethrough for permitting volatilized material to pass from the chamber out of the housing, and the mouthpiece is locatable relative to the first casing portion so as to cover the opening with the volatilized material flow path fluidly connected to the channel of the mouthpiece via the inlet of the mouthpiece when the cartridge is received in the recess.

10. Apparatus according to claim 7 , wherein the cartridge is movable through the opening, and the mouthpiece is locatable relative to the first casing portion at a position at which the cartridge is movable through the opening.

11. Apparatus according to claim 7 , wherein the apparatus is arranged to heat the smokable material to volatilize the at least one component of the smokable material without combusting the smokable material when the cartridge is received in the recess.

12. Apparatus according to claim 7 , wherein at least one of the first casing portion and the second casing portion contains a controller for controlling the supply of electrical power to the heating element from an electrical power source when the cartridge is received in the recess.

13. Apparatus according to claim 7 , wherein at least one of the first casing portion and the second casing portion contains a controller arranged to control heating of the heating element so as to cause heating of the smokable material to volatilize the at least one component of the smokable material without combusting the smokable material when the cartridge is received in the recess.

14. Apparatus according to claim 7 , wherein the seal defines the inlet.

15. Apparatus according to claim 7 , wherein the seal is resilient.
