[0036] The through-hole 42 may be formed on the other side of the body 10 opposite to the side of the body 10 in which the insertion space 12 is formed. The through-hole 42 may be formed in a cylindrical shape. The through-hole 42 is not limited to this and can be formed in a variety of sizes and shapes. Internal air and external air can be exchanged through the through-hole 42.

[0037] Therefore, the pressure difference between the inside and outside of the aerosol generator 100 can be improved.

[0038] The aerosol generating device 100 may further include a base 40 that forms the other side of the body 10 opposite to one side of the body 10 in which the insertion space 12 is formed.

[0039] The through-hole 42 may be formed in the base 40. The through-hole 42 may penetrate the base 40 along the thickness direction of the base 40, i.e., the length direction of the body 10.

[0040] The base 40 may include a recessed portion 44 around the through hole 42. The recessed portion 44 may be recessed to a predetermined depth, away from the through hole 42. The recessed portion 44 may have the same shape as the through hole 42. The size of the recessed portion 44 may be larger than the size of the through hole 42. For example, the through hole 42 and the recessed portion 44 may be circular.

[0041] The membrane 50 can be seated in the recess 44. The recess 44 can guide the installation position of the membrane 50. The recess 44 can prevent the membrane 50 from detaching.

[0042] The base 40 may include a ground portion 45 that closes the other open side of the body 10. The ground portion 45 can form a plane perpendicular to the length of the body 10. The ground portion 45 can form a curved surface with both ends bent to one side. For example, the ground portion 45 can be formed as a curved surface with both ends bent in the length direction of the body 10.

[0043] The base 40 may include a foundation 46. The foundation 46 may have a raised flat surface 460 that rises from the base 40 and on which a gasket 50 (described later) is seated. The foundation 46 may be formed rising from the ground portion 45. A flow channel for air can be formed between the side surface of the foundation 46 and the inner surface of the body 10. For example, a tapered flow channel 82 can be formed between the side surface of the foundation 46 and the inner surface of the body 10.

[0044] The base 40 can be bent and extended to form a curved surface in the longitudinal direction of the body 10. The base 40 may include a rounded base side portion 48.

A charging hole 452 may be formed in the base 40 through which the charging terminal 164 passes. The charging hole 452 may be formed in a variety of shapes and sizes. For example, the charging hole 452 may be formed in the shape of a rectangle with rounded corners.

[0049] The membrane 50 may be placed at the inlet or outlet of the through-hole 42. The membrane 50 may be placed inside the through-hole 42. The membrane 50 may be placed on the outer surface of the base 40. The membrane 50 may be placed outside the body 10. The membrane 50 may be a film. The membrane 50 may be a functional film. The membrane 50 may selectively allow fluid to pass through. The membrane 50 may not be permeable to liquid. The membrane 50 may be permeable to gas. The membrane 50 may allow gas to pass through in both directions, and liquid to pass through in only one direction. The membrane 50 may not allow liquid flowing from the outside to the inside of the body 10 to pass through, but may allow liquid flowing from the inside to the outside of the body 10 to pass through. The membrane 50 may allow liquid inside the aerosol generator 100 to be discharged to the outside and may block external liquid from flowing into the aerosol generator 100.

[0050] Therefore, the pressure difference between the inside and outside of the aerosol generating device 100 can be improved.

[0051] The membrane 50 may be formed from a woven fabric. The membrane 50 may be formed from a synthetic resin. The synthetic resin may have selective permeability. For example, the synthetic resin may be Gore-Tex®.

[0055] The body 10 may be cut open in part on its side so that the cover 30 can be fitted. The body 10 may be cut open to a shape corresponding to the shape of the cover 30. When the cover 30 is attached to the body 10, the base 40 may no longer be exposed to the outside.

[0056] The cover 30 may include rounded and extended cover side portions 36. The cover side portions 36 may be formed horizontally with respect to the longitudinal direction of the body 10. A projection 362 may be formed on the inside of the cover side portion 36. The cover 30 can be mounted on the base 40 by inserting the projection 362 into a groove 482 formed in the base 40. The projection 362 may be formed perpendicular to the cover side portion 36 toward the inside of the body 10. The projection 362 may be formed perpendicular to the longitudinal direction of the body 10.

[0057] The cover 30 may include a cover rounding portion 34 that is rounded to form a curved surface. The cover rounding portion 34 may correspond to a base rounding portion 47. The body 10 includes a recess configured to accommodate the cover 30 when the cover 30 is fitted.

[0058] Guide ribs 342 may be formed on the inside of the cover rounding portion 34. The guide ribs 342 may be formed along the length of the body 10.
