An internal space 50 is formed between the protruding tube 1020 and the cigarette support 4 and between the heater fixing part 1040 and the cigarette support 4. One side of the inner space 50 is in communication with the inflow passage 1004g through which the outside air is introduced when the cigarette support 4 is mounted to the protruding tube 1020, and the other side is in communication with the heater insertion hole 10b.

According to this structure, the outside air introduced into the inflow passage 1004g flows into the interior space 50 along the gap between the cigarette support 4 and the protrusion 1020, and the interior space 50 according to the user's suction action. In through the heater insert 10b can be suctioned through the cigarette 2000 to the user.

That is, the interior of the cigarette support part 4 into which the cigarette 2000 is inserted and the internal space 50 may communicate with each other through a minute gap formed between the heater 1030 and the heater insertion hole 10b. In this case, the cigarette 2000 is heated to generate an aerosol, but at the same time, the aerosol is also liquefied to form a liquid material at the end 2000b of the cigarette 2000 and is formed between the heater 1030 and the heater insertion hole 10b. The gap may be leaked toward the inner space 50. In addition, the aerosol remaining in the internal space 50 may be liquefied and formed on the inner wall surface of the protruding tube 1020, and may flow down along the inner wall surface of the protruding tube 1020. Herein, the term "liquid substance" may refer to a water or aerosol substance contained in the platelet medium of the cigarette 2000.

If the liquid substance remaining in the inner space 50 flows into a gap formed between the protrusion tube 1020 and the cigarette support 4, the liquid substance is formed along the inner wall of the protrusion tube 1020.

In order to solve this problem, the round surface 1040r of the heater fixing part 1040 has a gap between the protrusion tube 1020 and the heater fixing part 1040 of the liquid material flowing into the internal space 50. It may serve as a kind of breakwater that collects the liquid material so as not to penetrate into the interior of the aerosol generating device (1000).

In addition, the round surface 1040r may assist the liquid material generated in the inner space 50 to be delivered to the heater 1030 side without being fixed to the edge of the inner space 50. For example, the liquid material delivered to the heater 1030 by the round surface 1040r may be heated by the heater 1030 and aerosolized again.

In addition, the aerosol generating device 1000 has a sealing member 1050 interposed between the protruding tube 1020 and the heater fixing unit 1040 to seal the gap between the protruding tube 1020 and the heater fixing unit 1040. It may further include.

The heater fixing part 1040 may further include a sealing groove 1040h formed to be drawn in from a surface contacting the protruding tube 1020, and the sealing member 1050 may be installed in the sealing groove 1040h. However, the embodiment is not limited thereto, and the sealing member 1050 may be installed in a sealing groove (not shown) formed at the side of the protruding tube 1020.

Although the embodiment shown in the drawings depicts the case in which the sealing member 1050 is circular, the embodiment is not limited thereto. The sealing member 1050 includes an elastic material, and protrudes to prevent the liquid material from penetrating into the aerosol generating device 1000 through a gap formed between the protrusion tube 1020 and the heater fixture 1040. It is not limited to a specific shape as long as it serves to seal the gap between the tube 1020 and the heater fixture 1040.

The sealing member 1050 overflows the protruding pipe 1020 and the heater fixing portion 1040 if the liquid substance accumulated in the internal space 50 flows higher than the height a of the round surface 1040r of the heater fixing portion 1040. Even when flowing along the gap formed between the), it is possible to protect the battery 1100 and the controller 1200 installed therein by preventing the liquid material from penetrating into the interior of the aerosol generating device (1000).
