Aerosol generating device including detachable vaporizer

1. An aerosol-generating device comprising:

a case including a cigarette insertion hole configured to receive a cigarette;

a vaporizer configured to be combined with and detached from the case independently of the cigarette, and configured to provide an aerosol to the cigarette inserted in the cigarette insertion hole; and

a detachment manipulation unit installed in the case and configured to perform, according to user manipulation, a first operation of maintaining a state in which the vaporizer is combined with the case and a second operation of allowing separation of the vaporizer from the case.

2. The aerosol-generating device of claim 1 , wherein the detachment manipulation unit comprises:

a first link member slidable in a horizontal direction according to user manipulation; and

a second link member engaged with the first link member and slidable in a vertical direction by a sliding motion of the first link member, and

wherein the first link member comprises a button member which is exposed to outside of the case and causes the first link member to slide in the horizontal direction according to user manipulation.

3. The aerosol-generating device of claim 2 , wherein

the second link member comprises a protruding member protruding toward the first link member,

the first link member further comprises an accommodating groove that accommodates the protruding member, and

a portion where the protruding member and the accommodating groove contact each other is an inclined surface.

4. The aerosol-generating device of claim 2 , wherein

the detachment manipulation unit further comprises an elastic member that elastically presses the second link member to have resilient force in a direction toward the first link member.

5. The aerosol-generating device of claim 4 , wherein

the case comprises a base unit that supports the elastic member.

6. The aerosol-generating device of claim 2 , wherein

the first link member further comprises a first rail member extending in the horizontal direction, and

the second link member further comprises a second rail member extending in the vertical direction,

wherein the case comprises:

a first guide member accommodated in the first rail member; and

a second guide member accommodated in the second rail member,

wherein the first rail member moves along the first guide member as the first link member slides in the horizontal direction, and

wherein the second rail member moves along the second guide member as the second link member slides in the vertical direction.

7. The aerosol-generating device of claim 6 , wherein

the first rail member and the second rail member are formed as stepped grooves in surfaces of the first link member and the second link member or as through-holes passing through the first link member and the second link member, to accommodate the first guide member and the second guide member, respectively.

8. The aerosol-generating device of claim 6 , wherein

when the detachment manipulation unit is in the first operating state, the first guide member is engaged with one end of the first rail member to limit sliding in a direction in which the first link member is separated from the case.

9. The aerosol-generating device of claim 6 , wherein

when the detachment manipulation unit is in the second operating state, the first guide member is engaged with the other end of the first rail member to limit sliding in a direction in which the first link member is inserted into the case.

10. The aerosol-generating device of claim 6 , wherein

when the detachment manipulation unit is in the first operating state, the second guide member is engaged with one end of the second rail member to limit sliding of the second link member in a direction toward the first link member.

11. The aerosol-generating device of claim 6 , wherein

when the detachment manipulation unit is in the second operating state, the second guide member is engaged with the other end of the second rail member to limit sliding of the second link member in an opposite direction of the first link member.

12. The aerosol-generating device of claim 2 , wherein

the second link member comprises a fastening protrusion protruding toward the vaporizer, and

the vaporizer comprises a fastening groove that accommodates the fastening protrusion.

13. The aerosol-generating device of claim 12 , wherein

the fastening protrusion comprises a stopper protruding upward, and

the fastening groove is formed upward to accommodate the stopper when the stopper moves upward, and

wherein the stopper

is accommodated in the fastening groove when the detachment manipulation unit is in the first operating state, thereby limiting movement of the vaporizer in the horizontal direction, and

moves downward to be separated from the fastening groove when the detachment manipulation unit is in the second operating state, thereby allowing the vaporizer to move in the horizontal direction.

14. The aerosol-generating device of claim 13 , wherein

the stopper comprises an inclined surface, and

when the vaporizer is being combined with the case, the vaporizer contacts the inclined surface and moves the stopper downward by sliding over the inclined surface.

15. The aerosol-generating device of claim 12 , wherein

the case comprises a guide hole that exposes the fastening protrusion to the outside as the fastening protrusion penetrates the case,

wherein the guide hole is formed to extend in the vertical direction such that the fastening protrusion is movable in the vertical direction along the guide hole.
