[0022] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as those commonly understood by one of ordinary skill in the art to which the disclosure belongs. The terms used in the specification of the disclosure are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the disclosure.

[0023] Hereinafter, with reference to the attached drawings of the entire specification, an aerosol generating device 100 according to an embodiment will be described in detail through specific examples.

[0024] FIG. 1 is a 3-dimensional view of an aerosol generating device according to an embodiment; FIG. 2 is a cross-sectional view of the aerosol generating device of FIG. 1; and FIG. 3 is another cross-sectional view of the aerosol generating device of FIG. 1.

[0025] Referring to FIGS. 1, 2 and 3, an aerosol generating device 100 according to an embodiment may include a nozzle assembly 10, a housing assembly 20, a heating assembly 30, and a power assembly 40.

[0026] An intake chamber 102 may be disposed inside the nozzle assembly 10, and the nozzle assembly 10 may be mounted on the housing assembly 20.

[0027] The housing assembly 20 may include an air inlet 2202, a power mounting chamber 2204, an atomizing chamber 2602, and an air inlet chamber 2402. The air inlet 2202 is positioned on a side surface of the housing assembly 20, the air inlet 2202 is communicated with the intake chamber 102 through the air inlet chamber 2402 and the atomizing chamber 2602 in the order stated, and the power mounting chamber 2204 may be spaced apart from the air inlet chamber 2402.

[0028] The heating assembly 30 may be mounted inside the atomizing chamber 2602.

[0029] The power assembly 40 is mounted inside the power mounting chamber 2204, and the power assembly 40 may supply power to the heating assembly 30. At this time, the power assembly 40, the heating assembly 30, and the nozzle assembly 10 may be arranged sequentially and linearly.

[0030] According to the present embodiment, an aerosol generating material storage chamber 104 is disposed inside the nozzle assembly 10; according to another embodiment, the aerosol generating material storage chamber 104 may be disposed in the housing assembly 20.

[0031] Through the above structure, when a user puffs or inhales the aerosol generating device 100 along the nozzle assembly 10, an external gas may sequentially pass through the air inlet 2202 and the air inlet chamber 2402 and move to the atomizing chamber 2602. At this time, the liquid-phase aerosol generating material inside the aerosol generating material storage chamber 104 moves to the atomizing chamber 2602, and the aerosol generating material may be atomized inside the atomizing chamber 2602, thereby generating vapor. The vapor generated from the aerosol generating material is mixed with an external gas, and the mixture of the external gas and the vapor may move to the intake chamber 102 and be provided to the user when the user inhales.

[0032] In the above-described process, the power mounting chamber 2204 is separated from the air inlet chamber 2402, and the external gas does not come into contact with the power assembly 40 through the power mounting chamber 2204, and thus harmful substances generated after the power assembly 40 is heated may not be mixed with the external airflow. As a result, in the aerosol generating device 100 of the disclosure, harmful substances generated after the power assembly 40 is heated are not inhaled by the user.

[0033] According to the present embodiment, the nozzle assembly 10 may be mounted to the housing assembly 20 in a snap connection manner, and the nozzle assembly 10 may be placed in a sleeve-like form on the outside of the housing assembly 20.

[0034] A first sealing member 60 (refer to FIG. 9) is disposed between the nozzle assembly 10 and the housing assembly 20, and the first sealing member 60 may seal a gap between the nozzle assembly 10 and the housing assembly 20.

[0035] According to an embodiment, the air inlet 2202 is a circular aperture, and the power mounting chamber 2204 and the atomizing chamber 2602 may be respectively positioned on two sides of the central axis line of the air inlet 2202.

[0036] The power assembly 40 may include a battery having a cuboid-like shape, and the power mounting chamber 2204 and the air inlet 2202 may be separated by a spacer, and an electrode of the heating assembly 30 may be disposed to penetrate through the spacer and may be electrically connected to the power assembly 40.

[0037] According to another embodiment, the nozzle assembly 10 may be mounted to the housing assembly 20 in another manner, e.g., through soldering, and an aerosol generating material inlet may be disposed on the first sealing member 60.

[0038] However, the shapes of the air inlet 2202 and the power assembly 40 are not limited to the above-described embodiment, and, according to embodiments, the air inlet 2202 may have other shapes, such as a hole having a rectangular cross-section or a truncated cone-shaped hole, and the power assembly 40 may have other shapes, such as a cylindrical shape.

[0039] According to some embodiments, the aerosol generating device 100 may further include a microphone assembly 50.

[0040] The housing assembly 20 may further include a microphone mounting chamber 2404 and a microphone air passage 2406, wherein the microphone mounting chamber 2404 may communicate with the power mounting chamber 2204, and the air inlet chamber 2402 may communicate with the microphone mounting chamber 2404 through the microphone air passage 2406. At this time, the microphone assembly 50 is mounted inside the microphone mounting chamber 2404 and may separate the microphone air passage 2406 and the power mounting chamber 2204.

[0041] According to the structure described above, the microphone mounting chamber 2404 is independent from the air inlet chamber 2402, and the air passage within the aerosol generating device 100 is divided into two air passages, wherein one of the air passages (a first air passage) may sequentially pass through the air inlet 2202, the air inlet chamber 2402, the atomizing chamber 2602, and the intake chamber 102. Such an air passage (the first air passage) may serve to mix the external gas and smoke and provide a mixture thereof for inhalation by a user.

[0042] The other air passage (a second air passage) may sequentially pass through the air inlet 2202, the microphone air passage 2406, and the microphone mounting chamber 2404. The other air passage (the second air passage) may be utilized by the microphone assembly 50 to induce airflow, and the microphone assembly 50 may control opening and closing of the heating assembly 30.

[0043] A gas moving to the microphone mounting chamber 2404 does not pass through the atomizing chamber 2602, and it is difficult for the smoke inside the atomizing chamber 2602 to move into the microphone mounting chamber 2404, and thus the vapor may condense on the microphone assembly 50. The vapor condensed on the microphone assembly 50 may inhibit the formation of an aerosol generating material, and thus the microphone assembly 50 may be damaged.

[0044] Also, the power assembly 40 may also supply power to the microphone assembly 50, and, when the microphone mounting chamber 2404 communicates with the power mounting chamber 2204, the microphone assembly 50 may be more easily electrically connected to the power assembly 40.

[0045] The microphone assembly 50 separates the microphone air passage 2406 and the power mounting chamber 2204 from each other, such that a gas moving to the microphone mounting chamber 2404 through the microphone air passage 2406 does not come into contact with the power assembly 40, and, even when the gas inside the microphone mounting chamber 2404 flows back into the air inlet chamber 2402, no harmful substances on the surface of the power assembly 40 are carried into the air inlet chamber 2402.

[0046] In detail, according to the present embodiment, the microphone mounting chamber 2404 has a cylindrical shape, the microphone air passage 2406 also has a cylindrical shape, and the central axis line of the microphone mounting chamber 2404 may be arranged parallel to a direction from the power mounting chamber 2204 toward the atomizing chamber 2602. The microphone mounting chamber 2404 may be located on one side of the central axis line of the air inlet chamber 2402, the central axis line of the microphone air passage 2406 may be parallel to the central axis line of the microphone mounting chamber 2404, and the central axis line of the microphone air passage 2406 may be perpendicular to the central axis line of the air inlet 2202.

[0047] An end of the microphone mounting chamber 2404 facing a side opposite to the microphone air passage 2406 may communicate with the power mounting chamber 2204, the microphone assembly 50 may have a cylindrical shape, a side surface of the microphone assembly 50 and a sidewall of the microphone mounting chamber 2404 may contact each other, and the microphone assembly 50 may separate the microphone air passage 2406 and the power mounting chamber 2204 from each other.

[0048] According to another embodiments, the microphone mounting chamber 2404 may have a different shape, e.g.,, a cuboidal shape, and the microphone air passage 2406 may also have a different shape, e.g., a cuboidal shape. At this time, the central axis line of the microphone air passage 2406 may be a common line with the central axis line of the microphone mounting chamber 2404; and the central axis line of the microphone mounting chamber 2404 may be a common line with the central axis line of the air inlet chamber 2402.

[0049] FIG. 4 is an exploded view of the aerosol generating device of FIG. 1.

[0054] Through the structure described above, in the process of assembling the aerosol generating device 100, the power assembly 40 may be first mounted inside the power mounting chamber 2204, the microphone assembly 50 may be mounted inside the microphone mounting chamber 2404, and the first mounting bracket 24 may be mounted inside the housing 22, such that the power mounting chamber 2204 may be separated from the air inlet chamber 2402, and the air inlet 2202 may be communicated with the air inlet chamber 2402.

[0055] Also, the nozzle assembly 10 may be mounted on the second mounting bracket 26 to connect the atomizing chamber 2602 with the intake chamber 102, and, finally, after the second mounting bracket 26 is combined with the nozzle assembly 10, the entire structure may be mounted on the housing 22 to connect the air inlet chamber 2402 with the atomizing chamber 2602.

[0056] In other words, the aerosol generating device 100 of the disclosure may be assembled in a manner in which the first mounting bracket 24 and the housing 22 are assembled to each other and, at the same time, the nozzle assembly 10 and the second mounting bracket 26 are also assembled to each other.

At this time, after mounting the first mounting bracket 24 and the power assembly 40 to one sub-housing 222, the two sub-housings 222 are assembled to form the housing 22, thereby completing the assembly between the first mounting bracket 24, the housing 22, and the power assembly 40.

[0058] According to the present embodiment, a snap groove 2206 (refer to FIG. 2) is arranged on the housing 22, the snap groove 2206 has a cylindrical structure, and the air inlet 2202 may be arranged on the groove wall of the snap groove 2206 and penetrate through the outer surface of the housing 22.

In other words, the second mounting bracket 26 may be snap-connected to the housing 22.

[0062] According to another embodiments, the housing 22 and the first mounting bracket 24 may be connected in another manner, e.g., through soldering, the second mounting bracket 26 and the nozzle assembly 10 may also be connected through soldering, and the second mounting bracket 26 and the housing 22 may also be connected in another manner. For example, the second mounting bracket 26 may have a cylindrical structure, and the second mounting bracket 26 may be connected to the housing 22 by screws.

[0066] The microphone mounting chamber 2404 is disposed at the first protrusion 242, the microphone air passage 2406 penetrates through the second protrusion 244; the central axis line of the air inlet 2202 may be disposed in a common plane with one cross-section of the second protrusion 244, but may be disposed to not to intersect with the outer surface of the second protrusion 244.

[0067] By the above-described structure, under the action of the first protrusion 242 and the second protrusion 244, a location where the microphone air passage 2406 communicates with the air inlet chamber 2402 may be higher than the lower wall of the air inlet chamber 2402. As a result, when a user stops puffing the aerosol generating device 100 and the smoke inside the atomizing chamber 2602 flows back into the air inlet chamber 2402, the smoke in the air inlet chamber 2402 may also have difficulty moving into the microphone air passage 2406, and the possibility of the smoke coming into contact with the microphone assembly 50 may also be reduced.
