The terms "first," "second," and "third," etc., are used only for the convenience of describing this technical solution and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. Fluid communication between two spatial structures means that fluids such as gases and liquids can flow between them. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Please see Figures 1 to 4 This utility model discloses an embodiment of an aerosol generating device, which includes a housing 1, a support 2, a base 3, and a heating element 4. The housing 1 forms a receiving cavity, within which the support 2, base 3, and heating element 4 are disposed. The support 2 forms a receiving area, within which the base 3 and heating element 4 are disposed. The heating element 4 forms a heating chamber for accommodating an aerosol generating matrix 5. That is, the aerosol generating matrix 5 can be inserted into the heating chamber, thereby surrounding the aerosol generating matrix 5 and circumferentially heating it. When energized, the heating element 4 generates heat, heating and atomizing the aerosol generating matrix 5 within the heating chamber to generate aerosol. Specifically, the heating element 4 includes a heating substrate and a heating element disposed on the heating substrate. In some embodiments, the heating substrate is a tubular structure open at both ends, with the hollow portion forming the heating chamber. The heating substrate can be a metal tube open at both ends. The heating element can be a heating film disposed on the surface of the heating substrate. The aerosol generating device also includes a power supply unit, which includes components such as batteries. The heating film and the power supply unit are mechanically and / or electrically connected. When the heating film is powered on, it generates heat, which heats and atomizes the aerosol generating matrix 5 located in the heating chamber to generate aerosol.

[0033] Aerosols can be visible or invisible and may include vapors (e.g., fine particulate matter in a gaseous state, which are typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. The aerosol-generating matrix 5 is a processed article that, when heated, is capable of generating aerosols. The aerosol-generating matrix 5 can be in a liquid, fully solid, or semi-solid state. The aerosol-generating matrix 5 includes, but is not limited to, plant materials, fragrance materials, smoke-generating substances, adhesives, etc.

[0034] The aerosol generating device also includes an air intake channel that connects the outside atmosphere to the heating chamber. Under the suction force provided by the user, outside air can enter the heating chamber through the air intake channel, carrying the aerosol out for the user to draw in.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, the outer casing 1 is generally a longitudinally elongated hollow column, comprising a first sidewall 11 and a cover 12 that are joined together. The air intake channel includes at least one air inlet 10, which is formed at the junction of the first sidewall 11 and the cover 12. The air inlet 10 fluidly connects the outside atmosphere and the heating chamber to introduce outside air into the heating chamber. Because the air inlet 10 is located at the junction of the first sidewall 11 and the cover 12, and is hidden in the structural gap between the first sidewall 11 and the cover 12, the air inlet 10 has good concealment, resulting in a better overall aesthetic appearance of the aerosol generating device. Furthermore, the air inlet 10 can be formed together with the first sidewall 11 and the cover 12, eliminating the need for separate drilling at other locations on the outer casing 1, thus simplifying the manufacturing process.

[0036] like Figure 3 and Figure 4 As shown, in some embodiments, the cover 12 may be located on top of the aerosol generating device. The cover 12 has an exhaust channel 120, which is in fluid communication with the heating chamber and the outside atmosphere, for discharging aerosols. The exhaust channel 120 may be an exhaust channel 120 of a certain length or an exhaust port. In some embodiments, the aerosol generating device may further include a filter 6, which is installed at the exhaust channel 120 of the cover 12 and has an exhaust orifice 60, which is in fluid communication with the heating chamber and the outside atmosphere. The filter 6 is used to filter the aerosols generated in the heating chamber and discharge the filtered aerosols for the user to inhale. Alternatively, in some other embodiments, the filter 6 may be omitted, and the aerosol generating article may be inserted into the heating chamber. The aerosol generating article has an aerosol generating matrix 5 and a filter section. The heating chamber is located just outside the aerosol generating matrix 5, and the end of the filter section away from the aerosol generating matrix 5 extends out of the receiving chamber. The aerosol is filtered and discharged by the filter section of the aerosol generating article for the user to inhale.

[0037] In some embodiments, the first sidewall 11 and the cover 12 may be rotatably connected. A rotating assembly is provided between the cover 12 and the first sidewall 11. The rotating assembly allows the cover 12 to rotate relative to the first sidewall 11 between a closed position and an open position. When the cover 12 is flipped relative to the first sidewall 11 to the open position, the aerosol generating matrix 5 can be loaded into the heating chamber. Since the filter 6 is installed at the air outlet channel 120 of the cover 12, the filter 6 also flips when the cover 12 and the first sidewall 11 are flipped relative to each other. This constructs a flip-top aerosol generating device. When the first sidewall 11 and the cover 12 are rotatably connected, the first sidewall 11 and the cover 12 are two independent components. By placing the air inlet 10 at the joint between the first sidewall 11 and the cover 12, the concealment of the air inlet 10 can be fully utilized by the flip-top aerosol generating device.

[0038] like Figure 2 As shown, in some embodiments, a first notch 101 is provided on the side of the cover 12, and a second notch 102 is provided on the first sidewall 11. The first notch 101 and the second notch 102 together form the air inlet 10. Specifically, the first notch 101 is formed by a partial recess on the surface of the cover 12 facing the first sidewall 11 (the lower end surface of the cover 12); the second notch 102 is formed by a partial recess on the surface of the first sidewall 11 facing the cover 12 (the upper end surface of the first sidewall 11). The opening directions of the first notch 101 and the second notch 102 are opposite to each other. Therefore, it is only necessary to reserve the first notch 101 when the cover 12 is formed, and the second notch 102 is only necessary to reserve when the first sidewall 11 is formed, and the second notch 102 is formed during the forming process of the first sidewall 11. This eliminates the need for separate drilling at other locations on the first sidewall 11 or the cover 12, simplifying the manufacturing process.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, at least one recessed area 13 is provided at the junction of the first sidewall 11 and the cover 12, and the air inlet 10 is located within the recessed area 13. This recessed area 13 serves as an operating position for the user to flip the cover 12; the user can place their hand within the recessed area 13 to facilitate applying force to open the cover 12. Figure 1 and Figure 2In the illustrated embodiment, the recessed region 13 has a certain length and extends circumferentially along the structural gap between the first sidewall 11 and the cover 12. The number of air inlets 10 is not limited to one. In some embodiments, two or more air inlets 10 may be provided, with the plurality of air inlets 10 spaced apart circumferentially along the structural gap between the first sidewall 11 and the cover 12. The plurality of air inlets 10 may be distributed at intervals within the recessed region 13 along the extension direction of the recessed region 13. Further, two air inlets 10 may be symmetrically arranged on the outer shell 1.

[0040] like Figure 2 As shown, in some embodiments, a first groove 131 extending circumferentially along the side of the cover 12 is formed by a partial recess on the side surface, and a second groove 132 extending circumferentially along the side surface of the first sidewall 11 is formed by a partial recess on the side surface. The first groove 131 and the second groove 132 together define the recessed area 13. Similarly, the first groove 131 can be formed during the molding process of the cover 12, and it is only necessary to reserve the first groove 131 when the cover 12 is molded; the second groove 132 can be formed during the molding process of the first sidewall 11, and it is only necessary to reserve the second groove 132 when the first sidewall 11 is molded. Furthermore, the area of ​​the recessed area 13 can be larger than the area of ​​the air inlet 10, and the air inlet 10 is smaller than the recessed area 13. The air inlet 10 can be better hidden in the recessed area 13, which is beneficial to the overall aesthetics of the aerosol generating device.

[0041] like Figure 2 As shown, in some embodiments, the outer contour of the air inlet 10 is racetrack-shaped, with a length of 4 mm and a width of 0.5 mm. Alternatively, in other embodiments, the air inlet 10 may have other shapes and sizes, which are not limited by this invention.

[0042] like Figure 4 As shown, in some embodiments, the air intake passage further includes at least one first air intake passage 20 (see reference). Figure 4 (The section extending vertically by the dashed line) includes a first air intake channel 20 formed on the support 2. This first air intake channel 20 is in fluid communication with both the air inlet 10 and the heating chamber to introduce outside air into the heating chamber. The air flows through the aerosol generation matrix 5 within the heating chamber to carry the aerosol out for the user to inhale. This first air intake channel 20 preheats the air entering the heating chamber, improving atomization efficiency.

[0043] Combination Figure 5 and Figure 6As shown, in some embodiments, the support 2 includes a second sidewall 21. A first air intake channel 20 is formed inside the second sidewall 21. It should be noted that the interior of the second sidewall 21 refers to the interior of the solid structure of the second sidewall 21, which is distinct from the receiving area defined by the support 2. The first air intake channel 20 connects the outside atmosphere and the heating chamber in fluid communication through the air intake 10. Air flows through the aerosol generation matrix 5 in the heating chamber to carry away the aerosol, thereby reducing the suction resistance when the user inhales.

[0044] like Figures 5 to 8 As shown, in some embodiments, the second sidewall 21 has an outer wall surface 211 and an inner wall surface 212, wherein the outer wall surface 211 faces the first sidewall 11 of the housing 1, and the inner wall surface 212 faces the heating element 4. The outer wall surface 211 of the second sidewall 21 is partially recessed to form at least one third groove 22. The bracket 2 also includes at least one patch 24, which covers the outside of the third groove 22 (i.e., the opening side of the third groove 22 facing the first sidewall 11 of the housing 1). The bottom surface of the third groove 22 and the patch 24 define a first air intake channel 20. The bottom surface of the third groove 22 refers to the surface of the third groove 22 that is furthest from the outer wall surface 211 of the second sidewall 21. Alternatively, in some other embodiments, the patch 24 may not be provided, and the first air intake channel 20 may be directly provided inside the structure of the second sidewall 21 of the bracket 2.

[0045] like Figure 5 and Figure 6 As shown, in some embodiments, the area of ​​the patch 24 is smaller than the area of ​​the third groove 22. The patch 24 covers a portion of the third groove 22, and the remaining portion of the third groove 22 not covered by the patch 24 is in fluid communication with the air inlet 10. Specifically, a reserved area at the upper right corner of the third groove 22 is not covered by the patch 24, and this reserved area is directly opposite and connected to the air inlet 10. All the outside air entering from the air inlet 10 enters the first air intake channel 20 through the portion of the third groove 22 not covered by the patch 24.

[0046] Furthermore, such as Figure 8As shown, in some embodiments, the third groove 22 may include a first recessed area 221 and a second recessed area 222. The second recessed area 222 is located around the first recessed area 221. The recess depth H1 of the first recessed area 221 relative to the outer wall surface 211 is greater than the recess depth H2 of the second recessed area 222 relative to the outer wall surface 211, and the patch 24 is embedded in the second recessed area 222. The groove bottom surface of the first recessed area 221 and the patch 24 define a first air intake channel 20. The groove bottom surface of the first recessed area 221 refers to the surface of the first recessed area 221 that is furthest from the outer wall surface 211 of the second sidewall 21. Specifically, the patch 24 and the groove bottom surface of the second recessed area 222 are fitted together. The outer contour shape and size of the groove bottom surface of the second recessed area 222 are adapted to the outer contour shape and size of the patch 24.

[0047] like Figure 8 As shown, in some embodiments, the width of the bottom surface of the second recessed area 222 is greater than or equal to 1.1 mm to ensure that the bottom surface of the second recessed area 222 has sufficient adhesive area for the patch 24 to be attached thereto. The material of the patch 24 may include at least one of polycarbonate (PC), polyethylene terephthalate (PET), metal, and plastic.

[0048] like Figure 4 As shown, in some embodiments, a heat insulation layer 7 is provided between the inner wall surface 212 and the heating element 4. The heat insulation layer 7 is used to isolate the heat between the second side wall 21 of the support 2 and the heating element 4, so as to prevent the cold air in the first air intake channel 20 from contacting and carrying away the heat of the heating element 4, thereby avoiding affecting the heating effect of the aerosol generation matrix 5 and avoiding increased energy consumption. Further, the heat insulation layer 7 may include aerogel or other materials with heat insulation properties. Aerogel is a porous material with nanoscale pores and extremely high porosity, containing a large amount of air. The nanoporous structure of aerogel makes the material have extremely low thermal conductivity and good heat insulation effect. Therefore, using aerogel as the heat insulation layer 7 can further improve the heat insulation effect and thus reduce energy consumption.

[0049] like Figure 4 and Figure 9As shown, in some embodiments, the air intake channel further includes a second air intake channel 30 formed on the base 3, and the heating component 4 abuts against the base 3. The second air intake channel 30 is in fluid communication with the first air intake channel 20 and the heating chamber, respectively. That is, the first air intake channel 20 is in fluid communication with the heating chamber through the second air intake channel 30. Thus, the air inlet 10, the first air intake channel 20, the second air intake channel 30 and the heating chamber are in sequential fluid communication. External air flows through the air inlet 10, passes through the first air intake channel 20 and the second air intake channel 30, and then enters the heating chamber. The aerosol generated by the aerosol generating matrix 5 in the heating chamber is heated and atomized, and the resulting aerosol mixes with the air and is then discharged through the air outlet channel 120 for the user to inhale.

[0050] like Figure 4 As shown, in some embodiments, the heating element 4 is a tube extending through both ends, and the heating element 4 and the base 3 are nested together. For example, the heating element 4 may be sleeved around the base 3, or the base 3 may be sleeved around the heating element 4.

[0051] like Figure 9 As shown, in some embodiments, the base 3 includes a tube 31 and a seat 32 connected to each other. The tube 31 is tubular with both ends open, and a cavity is formed in the tube 31. The tube 31 can be a hollow cylinder, a hollow square prism, or other shapes. That is, the cross-sectional profile of the tube 31 can be a regular or irregular shape such as a circle, rectangle, triangle, or polygon. The tube 31 and the heating element 4 are coaxially arranged, and the cavity and the heating cavity are in fluid communication. Figure 4 As shown, in some embodiments, a sealing section 51 is connected below the aerosol generating matrix 5, and the sealing section 51 and / or the aerosol generating matrix 5 can be contained within the cavity. The second air inlet channel 30 includes the cavity and a plurality of first air inlets 301 spaced circumferentially along the pipe body 31, each first air inlet 301 penetrating the pipe wall of the pipe body 31. The number of first air inlets 301 can be two, three, four, five, etc. Each first air inlet 301 is in fluid communication with the cavity and the first air inlet channel 20, respectively. Air flowing from the first air inlet channel 20 to the second air inlet channel 30 is first diverted through the first air inlet 301 and then enters the cavity and the heating chamber sequentially. Since the first air inlet 301 is distributed circumferentially along the pipe body 31, the air from the first air inlet channel 20 enters the pipe cavity in different directions around the pipe body 31 and then flows into the heating chamber. As a result, the airflow entering the heating chamber is more uniform, avoiding the loss of kinetic energy caused by chaotic airflow, thereby improving the efficiency of aerosol carry-out.

[0052] Furthermore, to improve the uniformity of the intake airflow, in some embodiments, the spacing between each first intake hole 301 along the circumference of the pipe body 31 is equal, that is, the spacing between any two adjacent first intake holes 301 along the circumference of the pipe body 31 is equal. The maximum width of each first intake hole 301 can be greater than 1 mm. Specifically, each first intake hole 301 can be a regular or irregular shape such as a circle, rectangle, triangle, or polygon. When the first intake hole 301 is a circular hole, the maximum width of the first intake hole 301 refers to its diameter, that is, the diameter of the first intake hole 301 is greater than 1 mm; when the first intake hole 301 is a rectangular hole, the maximum width of the first intake hole 301 can refer to its maximum side length, that is, the maximum side length of the first intake hole 301 is greater than 1 mm; when the first intake hole 301 is a square hole, the maximum width of the first intake hole 301 refers to any side length, that is, any side length of the first intake hole 301 is greater than 1 mm. Furthermore, the maximum width of each first air inlet 301 can be greater than 1.2 mm, so that the airflow velocity through the first air inlet 301 is not too high, and there is sufficient air intake to meet the requirements of large flow rate suction.

[0053] like Figure 9 As shown, in some embodiments, the base 32 is disposed around the tube 31, and the cross-sectional dimension of the base 32 is larger than that of the tube 31. The base 32 and the tube 31 can be integrally formed or separate structures. The second air intake channel 30 also includes a second air intake hole 302 formed on the base 32. Specifically, the second air intake hole 302 is directly opposite the first air intake hole 301. The second air intake hole 302 is in fluid communication with the first air intake hole 301 and the first air intake channel 20, respectively. That is, the first air intake hole 301 and the first air intake channel 20 are in fluid communication through the second air intake hole 302. Thus, the air inlet 10, the first air intake channel 20, the second air intake hole 302, the first air intake hole 301, the tube cavity, and the heating cavity are in sequential fluid communication. Air from the first air intake channel 20 first passes through the second air intake hole 302 and then enters the first air intake hole 301, forming a two-stage air intake. The second air intake hole 302 plays a role in balancing the airflow.

[0054] like Figure 9 As shown, in some embodiments, the seat 32 has a first surface 321 facing away from the tube body and a second surface facing the tube body. A second air inlet penetrates the first surface 321 and the second surface. Combined with... Figure 3As shown, the seal 90 is sandwiched between the first surface 321 and the inner wall surface 212. Thus, the first surface 321 and the inner wall surface 212 are tightly fitted with the seal 90, thereby sealing the gap between the first surface 321 and the inner wall surface 212. Furthermore, the minimum distance between the first air inlet 301 and the first surface 321 can be greater than or equal to 1 mm to obtain a more uniform airflow. The minimum distance between the first air inlet 301 and the first surface 321 refers to the minimum distance between the first air inlet 301 closest to the first surface 321 and the first surface 321, that is, the vertical distance between the outer contour line of the first air inlet 301 closest to the first surface 321 and the first surface 321.

[0055] In some embodiments, the total area of ​​the second air inlet 302 is larger than the total area of ​​the first air inlet 301. For example... Figure 9 In the illustrated embodiment, there is one second air inlet 302, and the area of ​​this second air inlet 302 is greater than the sum of the areas of all the first air inlets 301. Alternatively, in some other embodiments, there may be more than one second air inlet 302. Because the total area of ​​the second air inlets 302 is greater than the total area of ​​the first air inlets 301, it can be ensured that the airflow through the second air inlets 302 is greater than the airflow through the first air inlets 301, ensuring that a sufficient amount of airflow reaches the first air inlets 301 through the second air inlets 302 and is diverted, thus preventing the problem of multi-stage air intake interception.

[0056] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
