As shown in FIG. 2, the intermediate member 170 for separation is formed along the lower circumference of the chamber 110, like the sealing member 190, and is a seal for fixing and supporting the chamber 110 and the heater member 150. The role of the member 190 may be assisted.

In the middle member 170 for separation and the sealing member 190 of the present invention, a hollow may be formed in the central portion, and the heater member 150 located at the lower portion may be exposed through the hollow portion.

As the heater member 150 is exposed through a hollow formed in the central portion of the sealing member 190 and the intermediate member 170 for separation, the liquid aerosol-generating material stored in the chamber 110 may pass therethrough. .

On the other hand, in the case of the existing liquid e-cigarette, as a person sucks in the liquid-type inhalation material inside the cartridge, a pressure change occurs inside the cartridge. At this time, air from the outside does not flow into the cartridge well due to silicon As time goes by, there is an inconvenience that it is difficult to absorb liquid-type inhalation substances.

In the aerosol generating device 100 according to an embodiment of the present invention, the negative pressure generated inside the chamber 110 as the liquid aerosol generating material inside the chamber 110 is atomized through the heater member 150 and discharged to the outside. In order to compensate for this phenomenon, air flow ports may be provided on the sealing member 190 and the intermediate member 170 for separation so that air introduced from the outside may flow into the chamber 110 .

3 is a plan view illustrating an intermediate member for separation and a heater member according to an embodiment of the present invention.

Referring to FIG. 3 , the intermediate member 170 for separation according to an embodiment of the present invention is formed along the rim area so that a hollow is formed in the central portion, so that air introduced from the outside can move toward the sealing member 190. It may include a plurality of first air passage spheres 173 spaced apart from each other in order to provide a path.

Accordingly, the heater member 150 is exposed through the hollow in the central portion. The hollow of the intermediate member 170 for separation may serve as an air flow path through which liquid aerosol-generating substances stored in the chamber 110 may go to the heater member 150 .

Air introduced from the outside may be introduced through the hollow portion of the intermediate member 170 for separation through the heater member 150 formed of a porous member, but is mainly introduced through the edge region of the intermediate member 170 for separation. more air volume Therefore, the air introduced into the rim area can easily pass through the intermediate member 170 for separation through the first air flow hole 173 and move toward the sealing member 170 located at the upper portion.

4 is a plan view illustrating a silicon member and a chamber according to an embodiment of the present invention.

Referring to FIG. 4 , the sealing member 190 according to an embodiment of the present invention may be formed along an edge area such that a hollow is formed in the central portion like the intermediate member 170 for separation, and the second air passage ( 193) and convex portions 195.

That is, FIG. 4 is a view showing the lower surface of the sealing member 190. When viewed from the bottom, the chamber 110 is exposed through the hollow portion of the sealing member 190. Conversely, when looking down from the top of the sealing member 190, the heater member 150 is exposed through the hollow portion of the sealing member 190. The hollow of the sealing member 190 may serve as an air flow path through which the liquid aerosol generating material stored in the chamber 110 goes to the heater member 150 .

The second air passage hole 193 is introduced from the outside and passes through the first air passage hole 173 of the intermediate member 170 for separation so that the air flowing in can move toward the upper chamber 110. At this time, as shown in FIG. 4, the second air flow passages 193 according to the present embodiment may be spaced apart from each other by a predetermined distance.

At this time, the position 197 at which the first air passage ports 173 of the intermediate member 170 for separation and the second air passage ports 193 of the sealing member 190 are formed according to the embodiment of the present invention It is preferable to form at staggered positions so that they do not match each other.

In this way, the reason why the positions where the first air passage hole 173 and the second air passage hole 193 are formed are provided differently is that the liquid type aerosol generating material stored inside the chamber 110 This is to prevent a phenomenon that can flow downward through the passage hole 173 and the second air passage hole 193 at once.

Referring to FIG. 4 , the convex portion 195 may serve to form a separation space (gap) by a predetermined amount without completely overlapping the intermediate member 170 for separation and the sealing member 190 . That is, the separating intermediate member 170 and the sealing member 190 may form a separation space corresponding to the size of the convex portion.

For example, the convex portion 195 may have a size of several tens of micrometers based on a state in which the sealing member 190 is pressed by the chamber 110 and the liquid aerosol generating material.

In Figure 4, the convex portion 195 of the present invention is shown assuming to be implemented in a circular shape, but is not limited thereto, and may be protruded and formed in various shapes such as a trapezoidal shape and a triangular pyramidal shape.
