Abstract

An aerosol delivering device includes a case that is configured to accommodate an aerosol generating source and includes a discharge hole that is configured to discharge an aerosol generated by the aerosol generating source; a rotation body that is configured to rotate with respect to the case and includes a plurality of chambers sequentially arranged in a rotation direction, each of the plurality of chambers accommodating a medium and configured to pass the aerosol therethrough; and a position limiter that is configured to maintain a rotational position of the rotation body with respect to the case so that a position of at least one of the plurality of chambers corresponds to a position of the discharge hole.

First claim

The invention claimed is:

1. An aerosol delivering device comprising:
a case that is configured to accommodate an aerosol generating source and includes a discharge hole that is configured to discharge an aerosol generated by the aerosol generating source;
a rotation body that is configured to rotate with respect to the case, includes a plurality of chambers sequentially arranged in a rotation direction, each of the plurality of chambers accommodating a medium including a granule in a solid state such that the aerosol discharged from the discharge hole passes through the medium;
a position limiter that is configured to maintain a rotational position of the rotation body with respect to the case so that a position of at least one of the plurality of chambers corresponds to a position of the discharge hole; and
a transfer chamber arranged between the rotation body and the case and comprising a first surface surrounding the discharge hole, a transfer hole on the first surface aligned with the discharge hole, and walls extending from the first surface towards the rotation body forming a space, and is configured to transfer the aerosol discharged from the discharge hole through the transfer hole into the space and then to at least one of the plurality of chambers by buffering a flow of the aerosol such that the aerosol forms pressure inside the space between the rotation body and the case,
wherein the rotation body further comprises:
an upper plate that covers end portions of the plurality of chambers, and includes a plurality of upper through holes through which the aerosol, which passed through the medium of the plurality of chambers, is discharged out of the plurality of chambers; and
a plurality of lower through holes that are configured to transfer the aerosol delivered from the discharge hole to at least one of the plurality of chambers.

2. The aerosol delivering device of claim 1 , wherein the position limiter includes a protrusion supported by one from among the rotation body and the case, and a plurality of grooves arranged in the other from among the rotation body and the case, the plurality of grooves configured to couple to the protrusion to maintain the rotational position of the rotation body.

3. The aerosol delivering device of claim 2 , wherein the other from among the rotation body and the case further comprises a cam surface formed between the plurality of grooves, the cam surface configured to guide a movement of the protrusion.

4. The aerosol delivering device of claim 2 , wherein
the position limiter further includes a spring that is arranged between the rotation body and the case, and is configured to be pressed between the rotation body and the case while the rotation body rotates such as to be deformed elastically, wherein the protrusion is a part of the spring.

5. The aerosol delivering device of claim 4 , wherein
the spring has an arc shape, and
the aerosol delivering device further comprises:
an end support portion that is configured to support an end portion of the spring, and
an outer support portion that is configured to support at least a part of an outer side of the spring.

6. The aerosol delivering device of claim 1 , further comprising:
a rotation shaft that is connected to the case and rotatably supports the rotation body.

7. The aerosol delivering device of claim 1 , wherein the rotation body further comprises:
a mouthpiece that includes an outlet configured to discharge the aerosol passing through the medium accommodated in the plurality of chambers to the outside.

8. The aerosol delivering device of claim 1 , further comprising:
a sealing ring arranged between the mouthpiece and an edge of the upper plate.

9. The aerosol delivering device of claim 1 , wherein the plurality of upper through holes forms a plurality of groups of upper through holes, and each of the plurality of groups of upper through holes corresponds to each of the plurality of chambers.

10. The aerosol delivering device of claim 1 , wherein the plurality of lower through holes forms a plurality of groups of lower through holes, and each of the plurality of groups of lower through holes corresponds to each of the plurality of chambers.

11. The aerosol delivering device of claim 1 , further comprising:
a rotation guide arranged between the case and the rotation body and configured to guide a rotation operation of the rotation body,
wherein the case and the rotation body have a cylindrical shape.

12. The aerosol delivering device of claim 1 , wherein the medium of each of the plurality of chambers of the rotation body are different types from each other.

13. The aerosol delivering device of claim 12 , wherein the rotation body further comprises a plurality of marks that indicate the types of the medium included in the plurality of chambers and are arranged to correspond to each of the plurality of chambers.

14. The aerosol delivering device of claim 12 , further comprising:
a signal generator that is arranged between the rotation body and the case and is configured to indicate a type of the medium of one of the plurality of chambers through which the aerosol passes among the plurality of chambers according to the rotational position of the rotation body.

15. An aerosol generating device including the aerosol delivering device of claim 1 , further comprising:
an atomizer that is configured to generate the aerosol from the aerosol generating source of the aerosol delivering device to deliver the aerosol to the case.
