They do not necessarily indicate that the indicated device or element must have, be configured, or operate in a specific orientation, and should not be construed as limitations on the present disclosure. In addition, terms such as "first," "second," etc. are for the purpose of description only and should not be construed as indicating or implying relative importance.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. The terminology used in the specification of this disclosure is for the purpose of describing specific embodiments only and is not intended to limit the embodiments of this disclosure.

[0034] Hereinafter, with reference to the attached drawings of the entire specification, the aerosol generating device (100) provided in the embodiment of the present application will be described in detail through specific examples.

[0035] FIG. 1 is a three-dimensional view of an aerosol generating device according to one embodiment of the present disclosure; 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.

[0036] Referring to FIGS. 1, 2 and 3, an aerosol generating device (100) according to one embodiment may include a nozzle assembly (10), a housing assembly (20), a heating assembly (30) and a power assembly (40).

[0037] An intake chamber (102) is arranged inside the nozzle assembly (10), and the nozzle assembly (10) can be mounted on a housing assembly (20).

[0038] The housing assembly (20) may include an air inlet (2202), a power mounting chamber (2204), an atomizing chamber (2602), and an air intake chamber (2402). The air inlet (2202) is disposed on a side of the housing assembly (20), and the air inlet (2202) sequentially communicates with the intake chamber (102) through the air inlet chamber (2402) and the atomizing chamber (2602), and the power mounting chamber (2204) may be spaced apart from the air inlet chamber (2402).

[0039] The heating assembly (30) can be mounted inside the atomizing chamber (2602).

[0040] The power assembly (40) is mounted inside the power mounting chamber (2204), and the power assembly (40) can supply power to the heating assembly (30). At this time, the power assembly (40), the heating assembly (30), and the nozzle assembly (10) can be sequentially arranged in a linear manner.

[0041] In this embodiment, an aerosol generating material storage chamber (104) is disposed inside the nozzle assembly (10); in another embodiment, the aerosol generating material storage chamber (104) may be disposed in the housing assembly (20).

[0042] Through the above structure, when a user puffs or inhales the aerosol generating device (100) along the nozzle assembly (10), external gas can sequentially pass through the air inlet (2202) and the air inlet chamber (2402) and move to the atomization chamber (2602). At this time, the liquid-phase aerosol generating material in the aerosol generating material storage chamber (104) moves to the atomization chamber (2602), and the aerosol generating material can be atomized inside the atomization chamber (2602) to generate vapor. The vapor generated from the aerosol generating material is mixed with the external gas, and the mixed external gas and vapor can move to the intake chamber (102) and then be provided to the user when the user inhales.

[0043] In the process described above, the power mounting chamber (2204) is separated from the air inlet chamber (2402), and external gas does not come into contact with the power assembly (40) through the power mounting chamber (2204), so that the 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 present disclosure, the harmful substances generated after the power assembly (40) is heated are not inhaled by the user.

[0044] In this embodiment, the nozzle assembly (10) is mounted to the housing assembly (20) in a snap connection manner, and the nozzle assembly (10) can be placed in a sleeve form on the outside of the housing assembly (20).

[0045] A first sealing member (60) (see FIG. 9) is arranged between the nozzle assembly (10) and the housing assembly (20), and the first sealing member (60) can seal the gap between the nozzle assembly (10) and the housing assembly (20).

[0046] According to one embodiment, the air inlet (2202) is a circular aperture, and the power mounting chamber (2204) and the atomization chamber (2602) can be respectively positioned on either side of the central axis line of the air inlet (2202).

[0047] The power assembly (40) includes a battery having a rectangular shape, and the power mounting chamber (2204) and the air inlet (2202) are separated by a spacer, and the electrodes of the heating assembly (30) are arranged to penetrate the spacer so as to be electrically connected to the power assembly (40).

[0048] In another embodiment, the nozzle assembly (10) may be mounted to the housing assembly (20) in another manner, for example by soldering, and an aerosol generating material inlet may be positioned on the first sealing member (60).

[0049] However, the shapes of the air inlet (2202) and the power assembly (40) are not limited to the above-described embodiment, and depending on the embodiment, the air inlet (2202) may have other shapes, such as a hole having a rectangular cross-section or a truncated cone shape, and the power assembly (40) may have other shapes, such as a cylinder.

[0050] In some embodiments, the aerosol generating device (100) may further include a microphone assembly (50).

[0051] The housing assembly (20) may further include a microphone mounting chamber (2404) and a microphone air passage (2406), wherein the microphone mounting chamber (2404) is in communication with the power mounting chamber (2204), and the air intake chamber (2402) may be in communication with the microphone mounting chamber (2404) through the microphone air passage (2406). At this time, the microphone assembly (50) may be mounted inside the microphone mounting chamber (2404), and the microphone air passage (2406) and the power mounting chamber (2204) may be spaced apart.

[0052] 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 branches, and one of the branches (the first air passage) can sequentially pass through the air inlet (2202), the air inlet chamber (2402), the atomization chamber (2602), and the intake chamber (102). This branched air passage (the first air passage) can play a role of mixing external gas and smoke and providing it for the user to inhale.

[0053] Another branch of air passage (second air passage) may sequentially pass through the air inlet (2202), the microphone air passage (2406), and the microphone mounting chamber (2404). This other branch of air passage (second air passage) may be utilized by the microphone assembly (50) to induce airflow, and the microphone assembly (50) may control the opening and closing of the heating assembly (30).

[0054] The gas moving to the microphone mounting chamber (2404) does not pass through the atomization chamber (2602), and the smoke inside the atomization chamber (2602) has difficulty moving into the interior of the microphone mounting chamber (2404), so that 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, which may result in damage to the microphone assembly (50).

[0055] Additionally, the power assembly (40) may also supply power to the microphone assembly (50), and when the microphone mounting chamber (2404) is in communication with the power mounting chamber (2204), the microphone assembly (50) can be more easily electrically connected to the power assembly (40).

[0056] The microphone assembly (50) separates the microphone air passage (2406) and the power mounting chamber (2204) so ​​that the 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 so that even if the gas inside the microphone mounting chamber (2404) flows back into the air intake chamber (2402), no harmful substances on the surface of the power assembly (40) are carried into the air intake chamber (2402).

[0057] Specifically, in the present embodiment, the microphone mounting chamber (2404) is cylindrical, the microphone air passage (2406) is also cylindrical, and the central axis line of the microphone mounting chamber (2404) can be arranged to be parallel to the direction from the power mounting chamber (2204) toward the atomization chamber (2602). The microphone mounting chamber (2404) is 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) is parallel to the central axis line of the microphone mounting chamber (2404), and the central axis line of the microphone air passage (2406) can be perpendicular to the central axis line of the air inlet (2202).

[0058] One end of the microphone mounting chamber (2404) facing the opposite side of the microphone air passage (2406) is connected to the power mounting chamber (2204), the microphone assembly (50) has a cylindrical shape, the side of the microphone assembly (50) and the side wall of the microphone mounting chamber (2404) are in contact with each other, and the microphone assembly (50) can separate the microphone air passage (2406) and the power mounting chamber (2204).

[0059] In another embodiment, the microphone mounting chamber (2404) may have a different shape, such as, for example, a rectangular parallelepiped, and the microphone air passage (2406) may also have a different shape, such as, for example, a rectangular parallelepiped. In this case, 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 also be a common line with the central axis line of the air intake chamber (2402).

[0060] Figure 4 is an exploded view of the aerosol generating device of Figure 1.

[0061] Referring to FIG. 4, in some embodiments, the housing assembly (20) may include a housing (22), a first mounting bracket (24), and a second mounting bracket (26).

[0062] The first mounting bracket (24) and the second mounting bracket (26) can be sequentially mounted inside the housing (22) in a direction toward the nozzle assembly (10) in the housing (22).

[0063] The nozzle assembly (10) is mounted on the second mounting bracket (26), the air inlet chamber (2402), the microphone mounting chamber (2404) and the microphone air passage (2406) are disposed on the first mounting bracket (24), the air inlet chamber (2402) and the power mounting chamber (2204) are disposed on the housing (22), and the atomization chamber (2602) can be disposed on the second mounting bracket (26).

[0065] Through the structure described above, in the process of assembling the aerosol generating device (100), the power assembly (40) is first mounted inside the power mounting chamber (2204), then the microphone assembly (50) is mounted inside the microphone mounting chamber (2404), and the first mounting bracket (24) is mounted inside the housing (22), thereby separating the power mounting chamber (2204) from the air inlet chamber (2402) and connecting the air inlet (2202) with the air inlet chamber (2402).

[0066] Additionally, the nozzle assembly (10) can be mounted on the second mounting bracket (26) to connect the atomization chamber (2602) with the intake chamber (102), and finally, after the second mounting bracket (26) is combined with the nozzle assembly (10), the entire assembly can be mounted on the housing (22) to connect the air intake chamber (2402) with the atomization chamber (2602).

[0067] That is, the aerosol generating device (100) of the present disclosure can be assembled in a manner in which the first mounting bracket (24) and the housing (22) are assembled together, and the nozzle assembly (10) and the second mounting bracket (26) are also assembled together, and as a result, the assembly speed of the aerosol generating device (100) can be improved.

[0068] Specifically, the housing (22) includes two sub-housings (222), and the two sub-housings (222) are arranged to surround the air inlet (2202) and the power mounting chamber (2204), and the first mounting bracket (24) and the nozzle assembly (10) are fitted into the two sub-housings (222). At this time, after the first mounting bracket (24) and the power assembly (40) are mounted on 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).

[0069] In this embodiment, a snap groove (2206) (see FIG. 2) is arranged on the housing (22), the snap groove (2206) has a cylindrical structure, and the air inlet (2202) is arranged on the groove wall of the snap groove (2206) and can penetrate the outer surface of the housing (22).

[0070] A snap connection post (246) is protrudedly arranged on the outer surface of the first mounting bracket (24), the snap connection post (246) is snap-connected inside the snap groove (2206), the airflow guide hole (2408) is a circular hole, and the airflow guide hole (2408) can penetrate the snap post (246).

[0071] The second mounting bracket (26) includes a snap ring (264), and there is a gap between the inner surface of the snap ring (264) and the side wall of the atomizing chamber (2602), and a snap connection pass-through groove (2642) (see FIG. 7) can be arranged on the snap ring (264).

[0072] The nozzle assembly (10) includes an annular wall (12), and the annular wall (12) is inserted into the space between the inner surface of the snap ring (264) and the side wall of the atomization chamber (2602), and a snap connection member (122) (see FIG. 9) is protrudingly arranged on the outer surface of the annular wall (12), and the outer surface of the annular wall (12) is in contact with the inner surface of the snap ring (264), and the snap connection member (122) can be snap-connected to the groove wall of the snap groove (2206) with each other. That is, the second mounting bracket (26) can be snap-connected to the housing (22) with each other.

[0073] In another embodiment, the housing (22) and the first mounting bracket (24) may be connected in another manner, such as by soldering, and the second mounting bracket (26) and the nozzle assembly (10) may also be connected in a soldering manner, 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, but the connection method is not limited thereto.

[0074] FIG. 5 is a three-dimensional view of the first mounting bracket of the aerosol generating device of FIG. 1; FIG. 6 is a cross-sectional view of the first mounting bracket of the aerosol generating device of FIG. 1.

[0075] Referring to FIGS. 5 and 6, in some embodiments, the first mounting bracket (24) may include a first protrusion (242) and a second protrusion (244).

[0076] The first protrusion (242) and the second protrusion (244) are both positioned inside the air inlet chamber (2402), the first protrusion (242) protrudes against the lower wall of the air inlet chamber (2402), and the second protrusion (244) can protrude toward the surface of the nozzle assembly (10) with respect to the first protrusion (242).

[0077] The microphone mounting chamber (2404) is arranged in the first protrusion (242), and the microphone air passage (2406) passes through the second protrusion (244); the central axis line of the air inlet (2202) may be arranged in a common plane with one end surface of the second protrusion (244), but may not intersect with the outer surface of the second protrusion (244).

[0078] By the structure described above, under the action of the first protrusion (242) and the second protrusion (244), the place where the microphone air passage (2406) communicates with the air intake chamber (2402) may be higher than the lower wall of the air intake chamber (2402). As a result, when the user stops puffing the aerosol generating device (100), and the smoke in the atomizing chamber (2602) flows back into the air intake chamber (2402), the smoke in the air intake 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.

[0079] Specifically, in the present embodiment, both the first protrusion (242) and the second protrusion (244) have a cylindrical structure, and the size of the cross-section of the first protrusion (242) may be larger than the size of the cross-section of the second protrusion (244). In addition, the first protrusion (242) is arranged on one side of the central axis line of the second protrusion (244), and the central axis line of the first protrusion (242) may be parallel to the central axis line of the second protrusion (244), and the central axis line of the air inlet (2202) may be perpendicular to the central axis line of the first protrusion (242).

[0083] The outer surface of the third protrusion (262) is in contact with the lower wall of the air inlet chamber (2402), and a receiving chamber (2622) is arranged on the side of the third protrusion (262) facing the opposite side of the nozzle assembly (10), and a fixing plate (28) can be mounted inside the receiving chamber (2622). The first air inlet (2802) is arranged coaxially with the second air inlet (2604), and the air inlet chamber (2402) can be sequentially connected to the atomization chamber (2602) through the first air inlet (2802) and the second air inlet (2604).

[0085] In addition, the outer surface of the third protrusion (262) is in contact with the chamber side wall of the air inlet chamber (2402), so that the gap between the housing (22) and the first mounting bracket (24) is spaced apart from the air inlet chamber (2402), and the air inlet chamber (2402) cannot be communicated with the power mounting chamber (2204) through the gap between the housing (22) and the first mounting bracket (24).

[0086] Specifically, a second sealing member (70) is arranged between the first mounting bracket (24) and the second mounting bracket (26), and the second sealing member (70) seals the gap between the first mounting bracket (24) and the second mounting bracket (26), thereby allowing the gap between the housing (22) and the first mounting bracket (24) to be separated from the receiving chamber (2622).

[0087] In the present embodiment, both the air inlet chamber (2402) and the receiving chamber (2622) are similar to rectangular parallelepipeds, and in a direction along the central axis line of the air inlet port (2202), the first air guide port (2802) and the second air guide port (2604) are arranged inside the air inlet chamber (2402); the first air guide port (2802) is a semicircular-shaped opening, and the hole diameter of one end of the second air guide port (2604) that communicates with the first air guide port (2802) may be larger than the hole diameter of one end of the second air guide port (2604) that communicates with the atomization chamber (2602).

[0088] In other embodiments, the air inlet chamber (2402) and the receiving chamber (2622) may have other shapes, such as, for example, a cylinder; and along the central axis line of the air inlet port (2202), the first air guide port (2802) and the second air guide port (2604) may also be located on one side of the air inlet chamber (2402); the first air guide port (2802) may be a rectangular opening; and the second air guide port (2604) may be a cylinder.

[0089] In some embodiments, the heating assembly (30) is mounted on a side wall of the atomizing chamber (2602) facing the power assembly (40), the intake chamber (102) is located on one side of the heating assembly (30), and the second air inlet (2604) passes through the side wall of the atomizing chamber (2602) facing the power assembly (40), and the central axis line of the second air inlet (2604) can pass through the heating assembly (30).

[0090] Through the structure described above, the second air induction port (2604) is directly opposite the heating assembly (30), and the intake chamber (102) is located on one side of the heating assembly (30), so it can be determined that the second air induction port (2604) and the intake chamber (102) are misaligned with each other.

[0091] When the liquid aerosol generating material is atomized in the heating assembly (30) to form vapor, and external gas is introduced into the atomization chamber (2602) along the second air inlet (2604), the external gas moves to the heating assembly (30) and mixes with the vapor, and the external gas changes direction while being mixed with the vapor, moves to a position where the intake chamber (102) is connected to the atomization chamber (2602), and flows out of the nozzle assembly (10) along the intake chamber (102). In addition, the external gas can be more sufficiently mixed with the vapor through the above-described structure.

[0092] Specifically, in the present embodiment, the intake chamber (102) is similar to a truncated cone shape, and the cross-sectional area of ​​the intake chamber (102) may gradually increase in the direction opposite to the atomization chamber (2602). In addition, the atomization chamber (2602) may be similar to a rectangular parallelepiped, but is not limited thereto.

[0095] Through the structure described above, the microphone air passage (2406) is misaligned with the first air inlet (2802), and when the vapor inside the atomization chamber (2602) passes through the first air inlet (2802) and flows back into the air intake chamber (2402), the vapor can move to a position where the microphone air passage (2406) communicates with the air inlet chamber (2402), and the possibility of the vapor coming into contact with the microphone assembly (50) can be further reduced.

[0096] In some embodiments, the second air induction port (2604) includes a thick cylindrical air passage (26042) and a thin cylindrical air passage (26044) that are connected to each other and arranged coaxially, and the cross-sectional diameter of the thick cylindrical air passage (26042) is larger than the cross-sectional diameter of the thin cylindrical air passage (26044), and the air inlet chamber (2402) can be sequentially connected to the atomization chamber (2602) through the first air induction port (2802), the thick cylindrical air passage (26042), and the thin cylindrical air passage (26044).

[0097] By the structure described above, the cross-sectional area of ​​the thick cylindrical air passage (26402) is larger than the cross-sectional area of ​​the thin cylindrical air passage (26044), and in the process in which the external gas sequentially passes through the thick cylindrical air passage (26042) and the thin cylindrical air passage (26044), the flow rate of the external gas becomes faster, and the flow rate when the external gas moves into the atomization chamber (2602) becomes faster, so that it can be more sufficiently mixed with the vapor inside the atomization chamber (2602).

[0098] Specifically, a tubular structure in the shape of a truncated cone is arranged at one end of the thick cylindrical air passage (26042) toward the thin cylindrical air passage (26044), and the thin cylindrical air passage (26044) can be connected to the tubular structure in the shape of a truncated cone.

[0101] The aerosol generating material inlet chamber (2608) passes through one end of the second mounting bracket (26) facing the opposite side of the power assembly (40), and the aerosol generating material storage chamber (104) is sequentially connected to the atomizing chamber (2602) through the aerosol generating material inlet chamber (2608) and the aerosol generating material inlet (2606), and the aerosol generating material storage chamber (104), the aerosol generating material inlet chamber (2608), the aerosol generating material inlet (2606), and the atomizing chamber (2602) can be sequentially arranged linearly along the direction toward the power assembly (40).

[0102] Additionally, the heating assembly (30) covers the aerosol generating material inlet (2606), and the nozzle assembly (10) can be arranged in a sleeve form on the outer surface of the second mounting bracket (26).

[0103] A first sealing member (60) is arranged between the nozzle assembly (10) and the outer surface of the second mounting bracket (26), and the first sealing member (60) can seal the gap between the nozzle assembly (10) and the outer surface of the second mounting bracket (26).

[0104] According to the structure described above, after first injecting an aerosol generating material into the aerosol generating material storage chamber (104), the first sealing member (60) is placed between the second mounting bracket (26) and the nozzle assembly (10), and the nozzle assembly (10) is snap-connected to the second mounting bracket (26) so that the first sealing member seals the gap between the nozzle assembly (10) and the outer surface of the second mounting bracket (26), thereby completing the aerosol generating material injection process. At this time, the aerosol generating material storage chamber (104) penetrates one end of the nozzle assembly (10) facing the power assembly (40), and when the aerosol generating material storage chamber (104) is opened, the aerosol generating material can be more easily injected into the aerosol generating material storage chamber (104).

[0105] The aerosol generating material inlet chamber (2608) passes through one end of the second mounting bracket (26) facing the opposite side of the power assembly (40), and the aerosol generating material storage chamber (104) is in communication with the aerosol generating material inlet chamber (2608), so that the aerosol generating material in the aerosol generating material storage chamber (104) can be introduced into the aerosol generating material inlet chamber (2608) through the aerosol generating material storage chamber (104).

[0106] Specifically, the second mounting bracket (26) includes a sealing block (266), and an aerosol generating material inlet (2606) and an aerosol generating material inlet chamber (2608) are disposed in the sealing block (266), the aerosol generating material inlet chamber (2608) passing through one end of the sealing block (266) facing the opposite side of the power assembly (40), and the aerosol generating material inlet (2606) passing through one end of the sealing block (266) facing the power assembly (40).

[0107] The chamber wall of the aerosol generating material storage chamber (104) is arranged in a sleeve shape on the outer surface of the sealing block (266), the first sealing member (60) is made of a silica gel material, the first sealing member (60) is positioned between the aerosol generating material storage chamber (104) and the outer surface of the sealing block (266), and the first sealing member (60) can seal the gap between the nozzle assembly (10) and the outer surface of the second mounting bracket (26).

[0109] By the structure described above, when a user puffs the aerosol generating device (100), external gas can simultaneously pass through the air inlet (2202) consisting of two inlets and enter the air inlet chamber (2402). The movement directions of the external gas that passes through the inlet (2202) consisting of two inlets and enters the air inlet chamber (2402) are opposite to each other, and the external gas can merge inside the air inlet chamber (2402), and after the external gas merges, the external gas can move more uniformly into the atomization chamber (2602), so that the external gas can be more sufficiently mixed with the vapor in the atomization chamber (2602).

[0110] Specifically, in this embodiment, the number of inlets may be one, but is not limited thereto. In other embodiments, the number of inlets may vary. For example, the number of inlets may be two, or one inlet may have two, and another may have three.
