Aerosol generating device provided with rotary heater
An aerosol generating device provided with a rotary heater includes a casing having a hollow shape and including a path in which a cigarette is accommodated; a rotating member rotatably coupled to the casing; and a heater which has an end portion located inside the path to be inserted into the cigarette accommodated in the path, is connected to the rotating member to rotate along with the rotating member, and heats the cigarette when electricity is applied to the heater.
1. An aerosol generating device comprising:
a casing having an inner space that provides a path for accommodating a cigarette;
a rotating member rotatably coupled to the casing, and exposed to an outside of the casing such that the rotating member is rotatable by a user; and
a heater having an end portion located inside the path such that the end portion is inserted into and heats the cigarette accommodated in the path, and connected to the rotating member such that the heater rotates along with the rotating member.
2. The aerosol generating device of claim 1 , wherein
the rotating member rotates about a central axis in a longitudinal direction of the path.
3. The aerosol generating device of claim 2 , wherein
the heater rotates about the central axis in the longitudinal direction of the path.
4. The aerosol generating device of claim 1 , further comprising
a connector connecting the rotating member to the heater and rotating along with the rotating member and the heater.
5. The aerosol generating device of claim 4 , wherein
a protruding portion is provided on one of the connector and the rotating member,
a groove portion is provided on the other of the connector and the rotating member so that the protruding portion is inserted into the groove portion, and
the casing further comprises an intermediate container having a guide hole which allows the protruding portion to pass therethrough and extends in a circumferential direction of the rotating member to provide a movement path for the protruding portion while the rotating member rotates.
6. The aerosol generating device of claim 5 , wherein
the intermediate container further comprises a rotation limiter configured to limit movement of the protruding portion.
7. The aerosol generating device of claim 4 , wherein
the connector has a through-hole through which the end portion of the heater passes,
a coupling protrusion is provided on one of the heater and an inner surface of the connector,
a coupling groove is provided on the other of the heater and the through-hole so that the coupling protrusion is inserted into the coupling groove.
8. The aerosol generating device of claim 5 , further comprising
a pressing member provided in a path in which the protruding portion moves and configured to apply an elastic force with respect to movement of the protruding portion.
9. The aerosol generating device of claim 5 , wherein the casing further comprises:
an inner container having an inner space that provides the path in which the cigarette is accommodated, and located inside the intermediate container; and
an outer container for accommodating the intermediate container.
10. The aerosol generating device of claim 9 , further comprising
a cap coupled to an end portion of the inner container and having a hole through which the end portion of the heater passes.
11. The aerosol generating device of claim 5 , wherein
a movement protrusion is provided on one of the rotating member and the casing, and
a guide groove portion extending in the circumferential direction of the rotating member is provided on the other of the rotating member and the casing so that the movement protrusion is inserted into the guide groove portion and movement of the protruding portion is guided by the guide groove portion.
