[0040] This utility model discloses an electronic aerosol generating device, which includes an atomizing device and a power supply device connected to the atomizing device. This electronic aerosol generating device can be used for medical atomization, beauty atomization, and electronic cigarettes, and can be used to heat and atomize an atomizing liquid to form an aerosol.

[0041] like Figures 1 to 9 As shown, the atomizing device includes an atomizing chamber 10 and an atomizing mechanism disposed within the atomizing chamber 10. The atomizing mechanism includes a fixing component 20 and an atomizing core 30 installed in the fixing component 20.

[0042] See Figures 5 to 9 As shown, the atomizing core 30 includes a liquid guide 31 and a heating element 32 that cooperate with each other. The heating element 32 includes a first electrode part 321, a first heating part 322, a second heating part 323, a third heating part 324 and a second electrode part 325 connected in sequence.

[0043] The first heating element 322 and the third heating element 324 are on the same plane, while the second heating element 323 protrudes from the plane containing the first heating element 322 and the third heating element 324. The first heating element 322 and the second heating element 323 are attached to or embedded in the first atomizing surface (such as the lower surface of the liquid guide 31) of the liquid guide 31, and the second heating element 323 is installed inside the liquid guide 31, so that the liquid guide 31 has multiple heating atomizing areas, which can effectively improve the atomization volume, thereby optimizing the user experience and enhancing product competitiveness. Furthermore, when the atomized liquid flows from top to bottom to the first atomizing surface, the second heating element 323 can also heat a portion of the flowing atomized liquid, making the atomized liquid flow smoother.

[0044] In some embodiments, the second heating element 323 protrudes above the plane containing the first heating element 322 and the third heating element 324, and the second heating element 323 may not protrude below the plane containing the first heating element 322 and the third heating element 324. Preferably, the second heating element 323 is perpendicular to the plane containing the first heating element 322 and the third heating element 324.

[0045] like Figure 5 As shown, the second heating element 323 is square and flat. Further, the second heating element 323 may be a zigzag structure, a curved structure, or a square wave structure.

[0046] like Figure 10 and Figure 11As shown, in the second embodiment, the second heating element 323 includes a first sidewall 3231, a second sidewall 3232, and a third sidewall 3233. The first sidewall 3231 and the second sidewall 3232 are arranged parallel to each other and spaced apart. The third sidewall 3233 is perpendicularly connected to the first sidewall 3231 and the second sidewall 3232. The first sidewall 3231 is connected to the first heating element 322, and the second sidewall 3232 is connected to the third heating element 324. Preferably, the third sidewall 3233 is perpendicularly connected to the ends of the first sidewall 3231 and the second sidewall 3232 on the same side. Of course, the third sidewall 3233 is perpendicularly connected to the middle position of the first sidewall 3231 and the second sidewall 3232, which is not specifically limited here.

[0047] In some embodiments, the structure of the second heating element 323 is generally C-shaped, U-shaped, crescent-shaped, or circular. For example... Figures 12 to 14 As shown, in the third embodiment, the second heating element 323 is formed in a C-shaped columnar structure. For example... Figures 15 to 17 As shown, in the fourth embodiment, the second heating element 323 is formed in a circular column shape.

[0048] In some embodiments, the second heating element 323 is a solid structure or a hollow structure.

[0049] In some embodiments, the heating element 32 further includes a plurality of hook portions 326 connected to the first electrode portion 321 and the second electrode portion 325, and the hook portions 326 may be embedded inside the liquid guide 31.

[0050] For example Figures 7 to 9 As shown, in some embodiments, the liquid guiding body 31 includes a liquid guiding body 311, which has an upper surface and a lower surface opposite to each other. The lower surface of the liquid guiding body 311 forms the first atomizing surface. The liquid guiding body 311 is also provided with a through hole 312 that penetrates its upper surface and lower surface. The inner wall surface of the through hole 312 forms a second atomizing surface. The second heating part 323 is attached to or embedded in the second atomizing surface.

[0051] In some embodiments, such as Figure 9 As shown, the liquid guiding body 311 is provided with a first liquid inlet 313 and a second liquid inlet 314. The first heating element 322 is arranged opposite to the first liquid inlet 313, and the third heating element 324 is arranged opposite to the second liquid inlet 314. The atomizing liquid (such as e-liquid or medicine) can first enter the first liquid inlet 313 and the second liquid inlet 314, and then penetrate into the first atomizing surface, where it is heated and atomized by the first heating element 322 and the third heating element 324.

[0052] like Figure 7 and Figure 8As shown, in some embodiments, recesses may be provided on both sides of the liquid guiding body 311 in the width direction. These recesses penetrate the upper and lower surfaces of the liquid guiding body 311, forming airflow channels. Specifically, a portion of the aerosol formed by the heating and atomizing of the atomizing liquid by the first heating element 322, the second heating element 323, and the third heating element 324 can be guided from these recesses to the air duct 11 of the atomization chamber 10. The liquid guiding body 31 can be made of porous ceramic. It is understood that the material used to make the liquid guiding body 31 can also be porous materials with microporous capillary effects, such as foamed metal, porous glass, or rigid glass fiber tubes. Of course, the liquid guiding body 31 can also be liquid guiding cotton, etc., and its structure and material can be selected according to requirements; no specific limitations are made here.

[0053] The heating element 32 can be made of a metal, metal alloy, graphite, carbon, conductive ceramic, or other composite material of ceramic and metal materials with appropriate impedance. Metals or alloys with appropriate impedance include at least one of nickel, cobalt, zirconium, titanium, nickel alloys, cobalt alloys, zirconium alloys, titanium alloys, nickel-chromium alloys, nickel-iron alloys, iron-chromium alloys, iron-chromium-aluminum alloys, titanium alloys, iron-manganese-aluminum based alloys, or stainless steel.

[0054] The first heating element 322 and the third heating element 324 can be a heating wire bent into a disc shape or a heating plate in the shape of a grid. Alternatively, the first heating element 322 and the third heating element 324 can be a heating circuit, a heating track, a heating coating or a heating film, etc. Their structural shapes can be varied and can be selected according to requirements.

[0055] For example Figure 5 and Figure 6 As shown, the atomizing chamber 10 can be made of rigid insulating materials, such as phenolic plastics, polyurethane plastics, epoxy plastics, unsaturated polyester plastics, furan plastics, silicone resins, acrylic resins, and their modified resins. The atomizing chamber 10 is generally a longitudinal structure extending along a central axis, meaning its length along the central axis is much greater than its width and thickness in the two perpendicular directions within its cross-section. The atomizing chamber 10 has an air outlet at its upper end, and an air guide tube 11 extends downward around the periphery of the air outlet. The air outlet and the air guide tube 11 cooperate to form an air guide channel.

[0056] The lower end of the atomizing chamber 10 is open, and the interior of the atomizing chamber 10 forms a liquid storage chamber 12 for storing atomized liquid. The air guide tube 11 can be made of metal, such as stainless steel, and has a hollow cylindrical structure. Of course, the air guide tube 11 can also be made of a high-molecular polymer with good stability. Its material, shape and size can be selected and set according to the requirements, and no specific limitation is made here.

[0057] The fixing component 20 may include an upper sleeve 21, a lower sleeve 22, a base 23, and a conductive post 24. The upper sleeve 21 and the lower sleeve 22 cooperate with each other and are installed together in the base 23.

[0058] The upper sleeve 21 may include a top wall 211 and a peripheral wall 212 connected to the periphery of the top wall 211. The atomizing core 30 may be located in the inner cavity of the upper sleeve 21. An air guide tube 213 may be provided on the top wall 211. The lower part of the air guide tube 11 may be fixed in the air guide tube 213. The two may be fixed by an interference fit.

[0059] The top wall 211 may also be provided with a first liquid inlet 214 and a second liquid inlet 215. The first liquid inlet 214 is connected to the first liquid inlet 313, and the second liquid inlet 215 is connected to the second liquid inlet 314. The atomized liquid in the liquid storage chamber 12 can enter the first liquid inlet 313 through the first liquid inlet 214, and the atomized liquid in the liquid storage chamber 12 can enter the second liquid inlet 314 through the second liquid inlet 215. The through hole 312 is connected to the air guide cylinder 213.

[0060] The lower sleeve 22 has a cylindrical structure and may include a bottom wall 221 and a surrounding wall 222 connected to the periphery of the bottom wall 221. The upper end of the surrounding wall 22 is folded outward and downward to form a sleeve portion 223. The bottom wall 221 is provided with a plurality of first air inlets 224 and a plurality of first positioning holes 225. The inner cavity of the lower sleeve 22 can form an atomizing chamber, through which aerosol can enter the through hole 312, and then through the air guide tube 213 into the air guide pipe 11, and then be discharged through the air guide pipe 11 for consumption by the consumer. Preferably, the upper sleeve 21 and the lower sleeve 22 can be silicone sleeves.

[0061] The base 23 may include a bottom 231 and a side portion 232 connected to the periphery of the bottom 231. The sleeve portion 223 may be sleeved onto the upper part of the side portion 232. The outer wall surface of the side portion 232 may be provided with a snap-fit ​​portion 233 to cooperate with the snap-fit ​​groove of the inner side wall of the atomizing chamber 10, and the base 23 and the atomizing chamber 10 are fixed together by a snap-fit. The bottom 231 may be provided with a second air inlet 2311, which communicates with the first air inlet 224. The bottom 231 may also be provided with a second positioning hole, which is arranged opposite to the first positioning hole 225. There are two conductive posts 24, which are respectively inserted through the second positioning hole and the first positioning hole 225 to connect with the first electrode portion 321 and the second electrode portion 325 respectively.
