Abstract

The aerosol generating device includes: a cartridge including a mouthpiece movable between an open position and a closed position, and a body portion storing an aerosol generating material and including a first airflow passage in which airflow moves; and a main body including a coupling portion detachably coupled to the cartridge, and a holding portion holding the mouthpiece in the closed position.

Claims (37)

1 . An aerosol generating device comprising: a cartridge comprising: a mouthpiece configured to move between an open position and a closed position; and a body portion configured to store an aerosol generating material and comprising a first airflow passage; and a main body comprising: a coupling portion detachably coupled to the cartridge; and a holding portion configured to hold the mouthpiece in the closed position, wherein the cartridge further comprises a first elastic body elastically supporting the mouthpiece toward the open position.

2 . The aerosol generating device of claim 1 , wherein the holding portion provides a holding force to one end of the mouthpiece to hold the mouthpiece in the closed position.

3 . The aerosol generating device of claim 1 , wherein

the mouthpiece is rotatable around a rotation shaft, and

the first elastic body is a torsion spring located at the rotation shaft of the mouthpiece.

4 . The aerosol generating device of claim 1 , wherein the holding portion comprises a locking unit that is coupled to the mouthpiece when the mouthpiece moves to the closed position such that the mouthpiece is held in the closed position.

5 . The aerosol generating device of claim 4 , wherein

the holding portion further comprises a second elastic body configured to press the locking unit in one direction, and

when the mouthpiece moves from the closed position to the open position, the second elastic body is pressed to another direction such that the mouthpiece and the locking unit are uncoupled.

6 . The aerosol generating device of claim 1 , wherein the mouthpiece comprises a second airflow passage of which one end is connected to an outside of the aerosol generating device, and of which another end is connected to the first airflow passage in the open position.

7 . The aerosol generating device of claim 1 , wherein

the cartridge further comprises an atomizer, and

the coupling portion comprises an accommodating groove accommodating the body portion, and a connection terminal electrically connected to the atomizer.

8 . The aerosol generating device of claim 1 , wherein the main body further comprises a cover comprising an opening having a size corresponding to the mouthpiece, and wherein the cover is coupled to one side of the main body to which the cartridge is coupled such that a coupling state of the cartridge and the main body is maintained.

9 . The aerosol generating device of claim 1 , wherein the cartridge further comprises:

an atomizer; and

a storage,

wherein the body portion further comprises:

a first housing forming a portion of the first airflow passage of the storage; and

a second housing coupled to the first housing, and forming remaining portions of the first airflow passage and an inner space accommodating the atomizer.

10 . The aerosol generating device of claim 1 , wherein the cartridge further comprises:

an atomizer;

a first conductor connected to one surface of the atomizer; and

a second conductor connected to another surface of the atomizer.

11 . The aerosol generating device of claim 10 , wherein

the first conductor covers at least a portion of the one surface of the atomizer and at least a portion of an outer circumferential surface of the atomizer, and

the second conductor elastically pressurizes the atomizer in a direction from the other surface of the atomizer to the one surface of the atomizer.

12 . The aerosol generating device of claim 10 , wherein

the cartridge further comprises a circuit board electrically connected to

the atomizer through the first conductor and the second conductor, and

the circuit board comprises a resistor that eliminates noise of a signal applied to the atomizer.

13 . The aerosol generating device of claim 1 , wherein the cartridge further comprises:

an atomizer;

a storage;

a wick that absorbs the aerosol generating material stored in the storage; and

an absorbing plate arranged to cover at least a portion of the atomizer and configured to retain the aerosol generating material absorbed by the wick.

14 . The aerosol generating device of claim 1 , wherein the main body further comprises an inhalation detecting sensor located at the coupling portion.
