Abstract

Provided is an aerosol generating system including a holder configured to generate aerosol by heating a cigarette; and a cradle including an inner space into which the holder is inserted. The holder is configured to be tiltable with respect the cradle. The holder is inserted into the inner space of the cradle and then tilted to generate the aerosol.

Claims (38)

1. An aerosol generating device comprising:

a casing;

a hollow protruding tube elongated from the casing, and including an opening at an end of the protruding tube and a protruding portion protruded from an inner side of the protruding tube;

a heater elongated from the casing into the protruding tube such that an end portion of the heater is positioned inside the protruding tube; and

an accommodating portion coupled with the protruding tube,

wherein the accommodation portion includes:

a side wall forming a hollow tube shape inserted into the protruding tube;

an insertion hole at an end of the side wall, the insertion hole aligned with the opening of the protruding tube;

a bottom at the other end of the side wall, the bottom including a heater hole through which the heater passes; and

a through hole formed on an outer side of the side wall such that the protruding portion of the protruding tube is inserted into the through hole of the side wall.

2. The aerosol generating device of claim 1 , wherein the through hole extends at the outer surface of the side wall in a lengthwise direction of the protruding tube such that the protruding portion of the protruding tube is sliding in the extended through hole of the side wall.

3. The aerosol generating device of claim 1 , wherein the protruding portion has a length in parallel with a lengthwise direction of the protruding tube, and

wherein the through hole is formed at an outer surface of the side wall such that the protruding portion slides the through hole in the lengthwise direction of the protruding tube.

4. The aerosol generating device of claim 1 , wherein the accommodation portion includes an outer wall covering the side wall, and

wherein the protruding tube is inserted between the side wall and the outer wall of the accommodation portion such that the accommodation portion is coupled with the protruding tube.

5. The aerosol generating device of claim 1 , wherein the heater includes a rectangular section and a sharpened section at an end of the rectangular section, and

wherein the sharpened section is positioned inside of the protruding tube.

6. The aerosol generating device of claim 5 , wherein the end portion of the heater is a terminal end of the sharpened section of the heater.

7. The aerosol generating device of claim 1 , wherein the protruding tube includes an air hole penetrating a side of the protruding tube such that an air path is formed with the air hole and the through hole from an outside of the protruding tube to an inside of the accommodation portion.

8. The aerosol generating device of claim 7 , wherein the air hole includes a plurality of air holes, and

wherein at least one of the plurality of air holes is symmetrical with at least another of the plurality of air holes with reference to the heater.

9. An aerosol generating device comprising:

a casing;

a hollow protruding tube elongated from the casing, and including an opening at an end of the protruding tube and a protruding portion protruded from an inner side of the protruding tube;

a heater elongated from the casing into the protruding tube such that an end portion of the heater is positioned inside the protruding tube; and

an accommodating portion coupled with the protruding tube,

wherein the accommodation portion includes:

a side wall forming a hollow tube shape inserted into the protruding tube;

an insertion hole at an end of the side wall, the insertion hole aligned with the opening of the protruding tube;

a bottom at the other end of the side wall, the bottom including a heater hole through which the heater passes; and

a through hole adjacent to the bottom, the through hole forming an air path from an outside of the accommodation portion to an inside of the accommodation portion.

10. The aerosol generating device of claim 9 , wherein the through hole includes a plurality of through holes around the heater hole.

11. The aerosol generating device of claim 10 , wherein some of the plurality of through holes are symmetrical with the others of the plurality of through holes with reference to the heater hole.

12. The aerosol generating device of claim 11 , wherein the protruding tube includes an air hole penetrating a side of the protruding tube such that the air path is formed with the air hole and the through hole from an outside of the protruding tube to an inside of the accommodation portion.

13. The aerosol generating device of claim 12 , wherein the accommodation portion includes an outer wall covering the side wall, and

wherein the protruding tube is inserted between the side wall and the outer wall of the accommodation portion.

14. The aerosol generating device of claim 13 , further comprising an air introduction gap formed between an end of the outer wall of the accommodation portion and the casing such that the air path is formed with the air introduction gap, the air hole, and the through hole from an outside of the casing to an inside of the side wall of the accommodation portion.

15. The aerosol generating device of claim 14 , wherein a space is formed between the outer wall of the accommodation portion and the protruding tube of the casing such that the air path is expanded with the space.
