Abstract

An aerosol-generating device is disclosed. The aerosol-generating device of the present disclosure includes a door configured to open and close an insertion space into which a stick is inserted, a hinge member connected to the door to allow the door to be pivoted in the direction in which the stick is inserted, a magnetic body disposed at the door, a magnetic sensor configured to sense a magnetic field, and a controller configured to determine whether the stick is inserted into the insertion space using the magnetic sensor.

First claim

What is claimed is:

1. An aerosol-generating device comprising:
an insertion space configured to accommodate insertion of a stick;
a door comprising a magnetic portion and configured to cover an opening of the insertion space;
a hinge member coupled to the door and configured to allow the door to be pivoted inward into the insertion space and accommodated in an inner space defined by a recessed portion at the insertion space;
a magnetic sensor disposed adjacent to the inner space and configured to sense a magnetic field of the magnetic portion of the door when the door is pivoted into the inner space; and
a controller configured to determine insertion of the stick based on the magnetic sensor sensing the door being pivoted into the inner space.

2. The aerosol-generating device according to claim 1 , wherein the hinge member includes an elastic member configured to provide an elastic restoring force to the door towards a closed position.

3. The aerosol-generating device according to claim 1 , wherein the insertion space is defined by an inner wall and the hinge member is disposed at an upper region of the inner wall.

4. The aerosol-generating device according to claim 1 , further comprising:
a heater disposed adjacent to the insertion space and configured to provide heat to the stick,
wherein the controller is configured to:
interrupt supply of power to the heater during a standby mode of the device, and
release the standby mode based on detecting insertion of the stick.

5. The aerosol-generating device according to claim 1 , further comprising:
a cartridge comprising an inner wall and an outer wall, wherein a chamber is formed between the inner wall and the outer wall and is configured to store a pre-vaporized aerosol material,
wherein the inner wall of the cartridge defines the insertion space therein, and
wherein the inner wall comprises a recessed portion to define an inner space.

6. The aerosol-generating device according to claim 5 , wherein the hinge member is disposed adjacent to a portion at which the inner wall and the outer wall meet, and
wherein the door is accommodated in the inner space when fully pivoted into the insertion space.

7. The aerosol-generating device according to claim 5 , wherein the magnetic sensor is disposed inside the cartridge so as to be adjacent to the inner space.

8. The aerosol-generating device according to claim 5 , further comprising:
a wick disposed adjacent to an end of the insertion space and to be in communication with an interior of the chamber; and
a heater configured to provide heat to the wick,
wherein the controller is configured to:
interrupt supply of power to the heater during a standby mode of the device, and
release the standby mode based on detecting insertion of the stick.

9. The aerosol-generating device according to claim 5 , further comprising:
a main body formed to allow the cartridge to be coupled thereto; and
a cover covering at least a portion of the main body and at least a portion of the cartridge,
wherein a receiving passage is disposed at an upper surface of the cover to allow passage between the insertion space and outside the device,
wherein the hinge member is disposed at the upper surface of the cover and adjacent to an inner peripheral surface of the receiving passage, and
wherein the door is accommodated in the inner space when fully pivoted into the insertion space.

10. The aerosol-generating device according to claim 9 , wherein the magnetic sensor is disposed inside the main body so as to be adjacent to the inner space.
