Aerosol generating module and aerosol generating device

1 . An aerosol generating module, comprising:

a heating unit; and

an atomizing unit disposed adjacent to the heating unit and comprising an aerosol forming substrate,

wherein the heating unit comprises:

a first reservoir comprising a first material;

a second reservoir comprising a second material that generates heat by reacting with the first material;

a barrier plate disposed between the first reservoir and the second reservoir and formed of an impermeable material;

a first wall;

a second wall disposed opposite to the first wall and disposed adjacent to the atomizing unit; and

a barrier stick penetrating between the first wall and the second wall of the heating unit,

wherein the barrier plate comprises a through-hole having a diameter corresponding to a diameter of the barrier stick;

wherein when the barrier stick moves from the second wall toward the first wall, the first material and the second material are mixed, and

wherein the aerosol forming substrate is heated by heat generated by the mixed first material and second material.

2 . The aerosol generating module of claim 1 , wherein

the barrier stick is movable in a direction perpendicular to the first wall of the heating unit.

3 . The aerosol generating module of claim 1 , wherein

the barrier plate and the barrier stick are integrally formed, and the barrier plate is formed of a material having less tensile strength than the barrier stick, and

when the barrier stick moves from the second wall toward the first wall, the barrier plate is ruptured such that the first material and the second material are mixed.

4 . The aerosol generating module of claim 1 , wherein the atomizing unit is configured to discharge an aerosol from at least one of surfaces except for a surface adjacent to the heating unit.

5 . An aerosol generating device, comprising:

a housing;

a mouthpiece formed at one end of the housing; and

an aerosol generating module comprised in the housing,

wherein the aerosol generating module comprises:

an atomizing unit configured to store an aerosol forming substrate; and

a heating unit disposed adjacent to the atomizing unit and configured to heat the aerosol forming substrate,

wherein the heating unit comprises:

a first reservoir comprising a first material;

a second reservoir comprising a second material that generates heat by reacting with the first material;

a barrier plate disposed between the first reservoir and the second reservoir and formed of an impermeable material;

a first wall faces the mouthpiece;

a second wall disposed opposite to the first wall; and

a barrier stick penetrating between the first wall and the second wall of the heating unit,

wherein the barrier plate comprises a through-hole having a diameter corresponding to a diameter of the barrier stick;

wherein when the barrier stick moves from the second wall toward the first wall, the first material and the second material are mixed,

the aerosol generating device further comprises a push unit configured to push the barrier stick,

when the aerosol generating module is inserted into the housing, the push unit pushes the barrier stick from the second wall toward the first wall, and thus, the first material and the second material are mixed through the through-hole, and

wherein the aerosol forming substrate is heated by heat generated by the mixed first material and second material.

6 . The aerosol generating device of claim 5 , wherein a diameter of the push unit is smaller than a diameter of the through-hole.

7 . The aerosol generating device of claim 5 , wherein

the barrier plate is formed of a material having less tensile strength than the barrier stick, and the barrier plate and the barrier stick are integrally formed, and

when the aerosol generating module is inserted into the housing, the push unit pushes the barrier stick from the second wall toward the first wall such that the barrier plate is ruptured and the first material and the second material are mixed.

8 . The aerosol generating device of claim 5 , wherein the push unit is exposed from one surface of an interior of the housing by a user input.

9 . The aerosol generating device of claim 5 , wherein

the atomizing unit is configured to discharge an aerosol through an atomizing surface including at least one of surfaces except for a surface disposed adjacent to the heating unit, and

an airflow path is formed along an inner wall of the housing to guide the aerosol generated in the atomizing unit to the mouthpiece.

10 . The aerosol generating device of claim 9 , wherein the atomizing surface is formed in a mesh type through which the generated aerosol is able to pass.

11 . The aerosol generating device of claim 5 , wherein

the heating unit further comprises a side wall formed between the first wall and the second wall, and

the atomizing unit is disposed adjacent to at least a portion of the second wall and the side wall.
