[0040] Please refer to Figures 4 and 5 together. Figure 4 is a schematic structural diagram of the base 210 shown in Figure 3 from one angle. Figure 5 is a schematic structural diagram of the base 210 shown in Figure 3 from another angle. The base 210 includes a bottom plate 211, an electrode mounting portion 212, and a connecting portion 213. The electrode mounting portion 212 and the connecting portion 213 are both protruding from one side surface of the bottom plate 211.

[0041] The outer circumference of the electrode mounting portion 212 is recessed with a plurality of connection grooves 2121, which are spaced apart along the outer circumference of the electrode mounting portion 212. The connection grooves 2121 extend through the end surface of the electrode mounting portion 212 facing away from the base plate 211 and the outer circumference. In some embodiments, there may be three connection grooves 2121, spaced apart around the outer circumference of the electrode mounting portion 212.

[0042] The electrode mounting portion 212 is located at the center of the base plate 211. The radial dimension of the electrode mounting portion 212 is smaller than that of the base plate 211. The base 210 is provided with an electrode through-hole 214 and a third groove 215. The electrode through-hole 214 extends axially through the electrode mounting portion 212 and the base plate 211. The third groove 215 is recessed by the wall of the electrode through-hole 214. The third groove 215 extends through the surface of the base plate 211 facing away from the connecting portion 213. In some embodiments, the connecting groove 2121 is not connected to the electrode through-hole 214.

[0043] The connecting portion 213 is provided with a sealing groove 2131. The sealing groove 2131 surrounds the connecting portion 213. The sealing groove 2131 is recessed from the outer peripheral surface of the connecting portion 213. The sealing groove 2131 is spaced apart from the end surface of the connecting portion 213 facing away from the base plate 211. In other words, the sealing groove 2131 does not penetrate the end surface of the connecting portion 213 facing away from the base plate 211. Referring again to FIG. 2 , the atomizer 200 may further include a sealing ring 260, which is positioned within the sealing groove 2131. The sealing ring 260 may protrude relative to the sealing groove 2131.

[0044] Referring again to Figures 4 and 5 , the connection portion 213 is connected to one side of the base plate 211. The connection portion 213 and the electrode mounting portion 212 are located on the same side of the base plate 211. The connection portion 213 is disposed around the electrode mounting portion 212. A gap is provided between the connection portion 213 and the electrode mounting portion 212. In the axial direction of the substrate, the height of the connection portion 213 may be less than the height of the electrode mounting portion 212. In some embodiments, the base plate 211, the electrode mounting portion 212, and the connection portion 213 may be integrally formed.

[0045] Referring again to Figure 2 , the connecting portion 213 is connected to the side of the oil reservoir body 221 facing away from the mouthpiece 222. The oil reservoir opening 2002 faces the base 210. The oil reservoir body 221 is sleeved onto the outside of the connecting portion 213. A sealing ring 260 seals between the connecting portion 213 and the oil reservoir body 221, thereby forming a receiving space 201 between the base 210 and the oil reservoir 220. The side of the base 210 facing away from the oil reservoir 220 is used for connection to the main unit 100.

[0046] Please refer to Figure 6 again, which is a schematic diagram of the structure of the electrode assembly 230 shown in Figure 2. The electrode assembly 230 includes a first electrode 231, a second electrode 232, and an insulating member 233. The first electrode 231 is provided with an air inlet 2311. The air inlet 2311 extends through the first electrode 231 along the axial direction of the first electrode 231. A first protrusion 2312 may be provided at one end of the first electrode 231. The first protrusion 2312 is provided protruding from the outer periphery of the first electrode 231.

[0047] The insulating member 233 is provided with a first groove 2331 and a second groove 2332. The first groove 2331 is located at one end of the insulating member 233. The first groove 2331 is recessed from the inner surface of the insulating member 233. The first groove 2331 extends through one end surface and the inner surface of the insulating member 233.

The second groove 2332 is an annular groove.

[0048] The insulating member 233 is connected to the outer periphery of the first electrode 231. The groove wall of the first groove 2331 of the insulating member 233 is connected to the first protrusion 2312 of the first electrode 231. The groove wall of the first groove 2331 can limit the first protrusion 2312.

[0049] The second electrode 232 may be cylindrical. The second electrode 232 is provided with a second protrusion 2321 and a third protrusion 2322. The second protrusion 2321 is disposed around one end of the second electrode 232. The second protrusion 2321 protrudes from the outer surface of the second electrode 232. The second protrusion 2321 may be flush with the end surface of the second electrode 232. The third protrusion 2322 may be an annular cylindrical shape. The third protrusion 2322 is disposed protruding from the inner surface of the second electrode 232. One end surface of the third protrusion 2322 in the axial direction is flush with the end surface of the second electrode 232 facing away from the first protrusion 2312. The other end surface of the third protrusion 2322 in the axial direction has a gap with the end surface of the second electrode 232 on the side provided with the second protrusion 2321.

[0050] The second electrode 232 is sleeved on the outer periphery of the insulating member 233. The third protrusion 2322 is located in the second groove 2332. The groove wall of the second groove 2332 is connected to the third protrusion 2322.

[0051] The electrode assembly 230 is installed in the electrode through hole 214. The third protrusion 2322 of the second electrode 232 is connected to the groove wall of the third groove 215. The outer peripheral surface of the second electrode 232 is connected to the hole wall of the electrode through hole 214.

[0052] Please refer to Figures 7 and 8 in combination. Figure 7 is an exploded schematic diagram of the heating core 240 shown in Figure 2, and Figure 8 is a structural schematic diagram of the bracket 2412 and the fixing base 2411 shown in Figure 7. The heating core 240 includes an air collecting cover 241, a bracket 2412, an oil guide assembly 244 and a plurality of heating elements 245. The air collecting cover 241 includes an end cover 242 and a manifold 243. Exemplarily, the oil guide assembly 244 may include an oil guide medium 2440 and a fixing base 2411. The bracket 2412 is provided with a receiving cavity 2416. The oil guide assembly 244 and the plurality of heating elements 245 are located in the receiving cavity 2416 of the bracket 2412. The end cover 242 is connected to one side of the bracket 2412 to guide the smoke oil out. In some embodiments, the fixing base 2411 may be a porous medium material. The porous medium material can guide the smoke oil.

[0053] The axial direction of the heating core 240, the axial direction of the bracket 2412, the axial direction of the end cover 242, and the axial direction of the heating element 245 described below are the same direction, and the axial direction is also the length direction of the atomization device 1000. The circumferential direction of the heating core 240, the circumferential direction of the bracket 2412, the circumferential direction of the end cover 242, and the circumferential direction of the heating element 245 described below are the same direction. The radial direction is perpendicular to the axial direction. The radial direction of the heating core 240, the radial direction of the bracket 2412, the radial direction of the end cover 242, and the radial direction of the heating element 245 described below are the same direction. The radial direction is perpendicular to the axial direction.

[0054] In some possible embodiments, please refer to Figure 8, wherein the angle between the bracket 2412 and the fixing seat 2411 shown in Figure 8 is different from the angle between the bracket 2412 and the fixing seat 2411 shown in Figure 7. The bracket 2412 is connected to the outer periphery of the fixing seat 2411. That is, the fixing seat 2411 is fixedly arranged in the vent 2415 of the bracket 2412. The bracket 2412 includes a first end face 2413 and a second end face 2414, and the first end face 2413 and the second end face 2414 are arranged opposite to each other along the axial direction of the heating core 240. The bracket 2412 is provided with a vent 2415. The vent 2415 passes through the first end face 2413 and the second end face 2414.

[0055] The fixing base 2411 is provided with a plurality of mounting holes 2417. In some embodiments, a connecting hole (not shown) may be provided between two adjacent mounting holes 2417 to connect the two adjacent mounting holes 2417. The mounting holes 2417 extend axially through the fixing base 2411. It will be appreciated that the connecting hole allows the liquid in two adjacent mounting holes 2417 to pass through, thereby evenly distributing the liquid across the multiple oil-conducting media.

[0056] In some possible implementations, multiple mounting holes 2417 are arranged along the circumferential direction of the heating core 240. There is a gap between adjacent mounting holes 2417. In some embodiments, the number of mounting holes 2417 is three. The three mounting holes 2417 are arranged in a triangle.

[0057] The bracket 2412 is provided with a limiting groove 2418. The limiting groove 2418 passes through the bracket 2412 along the radial direction of the bracket 2412. The limiting groove 2418 passes through the first end surface 2413 of the bracket 2412. Exemplarily, the number of the limiting grooves 2418 is three. The three limiting grooves 2418 are arranged at intervals along the circumference of the bracket 2412. Exemplarily, the bracket 2412 and the fixing seat 2411 can be integrally formed. The structure of the bracket 2412 and the fixing seat 2411 can be hardware or plastic. Specifically, when the bracket 2412 and the fixing seat 2411 are hardware, the structural stability of the bracket 2412 and the fixing seat 2411 can be increased, and the possibility of deformation of the fixing seat 2411 and the bracket 2412 can be reduced. When the bracket 2412 and the fixing seat 2411 are plastic, the integral structure of the bracket 2412 and the fixing seat 2411 is easier to form. In some embodiments, the bracket 2412 and the fixing seat 2411 may also be two separate parts that are assembled to form the structure shown in FIG. 8 .

[0058] The bracket 2412 is connected to the outer periphery of the fixing seat 2411. The axial direction of the bracket 2412 can be perpendicular to the first end surface 2413 and the second end surface 2414. The bracket 2412 is further provided with a first connector 2419, which protrudes relative to the second end surface 2414. The first connector 2419 can be annular.

[0059] One side of the first end surface 2413 of the bracket 2412 protrudes relative to the fixing seat 2411 to form a second connecting body 2410. The second connecting body 2410 surrounds the outer periphery of the plurality of mounting holes 2417.

[0060] The limiting groove 2418 is connected to the mounting hole 2417. In some embodiments, each limiting groove 2418 is connected to one mounting hole 2417. Both ends of the bracket 2412 along the circumferential direction can protrude relative to the fixing seat 2411. The portion of the bracket 2412 between the two limiting grooves 2418 can protrude relative to the fixing seat 2411. The protruding portion is also the second connector 2410. In some embodiments, the portion of the bracket 2412 between the three limiting grooves 2418 is protruded relative to the fixing seat 2411. In other words, the number of the second connectors 2410 can be three.

[0061] Please refer to Figure 9, which is a schematic diagram of the structure of the gas collecting cover 241 shown in Figure 7. The end cover 242 has a manifold 2421. The manifold 2421 penetrates the end cover 242 along the axial direction of the end cover 242. The radial dimension of the manifold 2421 gradually decreases along the axial direction of the end cover 242.

[0062] End cap 242 is connected to second connector 2410 of bracket 2412. The end of end cap 242 with the larger end surface area faces fixed base 2411. The opening of manifold 2421 on the side facing fixed base 2411 covers all mounting holes 2417, connecting manifold 2421 with mounting holes 2417. The radial dimension of manifold 2421 gradually decreases as end cap 242 moves away from second end surface 2414.

[0063] In some embodiments, the end cap 242 is shaped like a funnel. When smoke passes through the fixing base 2411 and flows through the end cap 242, the smoke flow is concentrated to form a smoke flow with a smaller cross-sectional area. The smoke flow can efficiently pass through the mouthpiece 222 and enter the user's mouth.

[0064] The second connector 2410 of the bracket 2412 is connected to the electrode mounting portion 212 of the base 210. In some embodiments, the second connector 2410 can be located within the connection slot 2121 of the electrode mounting portion 212. The walls of the connection slot 2121 can limit the position of the second connector 2410. Each second connector 2410 corresponds to a connection slot 2121. This ensures that the bracket 2412 and the base 210 are relatively fixed in the circumferential direction of the heating core 240.

[0065] One end of the manifold 243 is connected to the side of the end cover 242 away from the fixed seat 2411. The manifold 243 is in communication with the manifold cavity 2421. The other end of the manifold 243 is connected to the first end of the mouthpiece 222. In the axial direction of the manifold 243, the end of the manifold 243 away from the end cover 242 abuts against the groove wall of the guide groove 2223 of the first section 2221. The diameter of the pipe inside the manifold 243 can be the same as the diameter of the first section 2221 of the mouthpiece 222. The inner diameter of the pipe inside the manifold 243 is smaller than the inner diameter of the bracket 2412, and the manifold 243 extends along the axial direction of the bracket 2412.

[0066] Referring again to Figure 7 , the oil guide assembly 244 is provided with a plurality of atomization channels 2441 arranged circumferentially around the heating core 240 , with each atomization channel 2441 extending axially through the oil guide assembly 244 . In one possible embodiment, the oil guide assembly 244 includes an oil-conducting medium 2440, which is provided with a plurality of atomization channels 2441. At least a portion of the oil guide assembly 244 is located within the vent 2415 of the bracket 2412 .

[0067] In one embodiment, the oil guide assembly 244 includes a plurality of oil guide media 2440 and a fixing seat 2411 as described above, and the plurality of oil guide media 2440 are arranged along the circumferential direction of the heating core 240. Each oil guide medium 2440 includes an oil guide body 2442 and a limiting portion 2443, and the limiting portion 2443 is connected to the outer periphery of the oil guide body 2442. An oil guide medium 2440 is provided with an atomization channel 2441. The atomization channel 2441 passes through the oil guide body 2442 along the axial direction of the oil guide medium 2440. Please refer to Figure 10, which is an assembly diagram of the heating core 240 shown in Figure 7. The oil guide body 2442 is located in the mounting hole 2417 of the fixing seat 2411, and the limiting portion 2443 is located in the limiting groove 2418 of the bracket 2412. The limiting portion 2443 protrudes relative to the outer circumferential surface of the bracket 2412 , or the limiting portion 2443 is flush with the outer circumferential surface of the bracket 2412 .

[0068] In some embodiments, when the limiting portion 2443 protrudes relative to the outer peripheral surface of the bracket 2412 or is flush with the outer peripheral surface, and when the oil storage cotton 250 is arranged around the bracket 2412, the oil storage cotton 250 can contact the limiting portion 2443 of the oil guide medium 2440. The tobacco oil can pass through the limiting portion 2443 from the oil storage cotton 250 to the oil guide body 2442. After the oil guide body 2442 is heated, the tobacco oil can be atomized into smoke, and the smoke can flow to the manifold 2421 through the mounting hole 2417 of the fixing seat 2411, and then flow out to the mouthpiece 222 through the manifold 243.

[0069] There are multiple heating elements 245 . One end of each heating element 245 is located in one atomizing channel 2441 and contacts the hole wall of one atomizing channel 2441 , and the other end of each heating element 245 protrudes relative to the oil guide assembly 244 .

[0070] In some embodiments, please refer to Figure 11, which is a schematic diagram of the structure of the heating element 245 shown in Figure 7. The heating element 245 includes a heating element 2451, a first pin 2452, and a second pin 2453. The heating element 2451 can be in the shape of a curved plate. The heating element 2451 can be bent along the circumferential direction of the heating element 245. The first pin 2452 and the second pin 2453 are connected to the same side of the heating element 2451. The first pin 2452 and the second pin 2453 can extend in the same direction.

[0071] Each heating body 2451 is located in an atomization channel 2441. The heating body 2451 contacts the hole wall of the atomization channel 2441. The first pin 2452 and the second pin 2453 extend from the atomization channel 2441. The first pin 2452 and the second pin 2453 extend toward the base 210. The first pin 2452 can be connected to the first electrode 231. The second pin 2453 can be connected to the second electrode 232. In some embodiments, the first pin 2452 is a positive pin and the first electrode 231 is a positive electrode. The second pin 2453 is a negative pin and the second electrode 232 is a negative electrode. Alternatively, the first pin 2452 is a negative pin and the first electrode 231 is a negative electrode. The second pin 2453 is a positive pin and the second electrode 232 is a positive electrode.

[0072] The oil-storage cotton 250 is located within the receiving space 201. The size of the oil-conducting medium 2440 can be adjusted based on the size of the oil tank 220. The oil-storage cotton 250 is disposed around the heating core 240. In some embodiments, the oil-storage cotton 250 can be cylindrical. The inner surface of the oil-storage cotton 250 abuts against the bracket 2412 of the heating core 240. The inner surface of the oil-storage cotton 250 contacts the stopper of the oil-conducting medium 2440.

[0073] In some embodiments, the e-liquid can be stored in the oil storage cotton 250. When the user uses the atomizer device 1000, the main unit 100 is connected to the atomizer 200. This allows the power supply in the main unit 100 to power the atomizer 200. Current can flow through the first electrode 231, the first pin 2452, the heater 2451, the second pin 2453, and the second electrode 232, and then flow to the negative terminal of the power supply. When current flows through the heater 2451, it heats up, thereby heating the e-liquid guide body 2442. The e-liquid in the e-liquid guide body 2442 is heated and atomized.

[0074] When a user draws from atomizer device 1000, air flows in through air inlet 2311 of first electrode 231 and passes through oil-conducting body 2442. After passing through oil-conducting body 2442, the airflow carries atomized tobacco liquid with it. The smoke-carrying gas then passes through manifold 2421, manifold 243, and mouthpiece 222, reaching the user's mouth, completing the puffing process.

[0075] The atomization device 1000 provided in the embodiment of the present application includes a plurality of heating elements 245. After the host 100 supplies power to the atomizer 200, the plurality of heating elements 245 can heat up at the same time or more than one heating element 245 can heat up at the same time, and heat the oil guide component 244 together. As the number of heating elements 245 increases, the contact area between the heating element 245 and the oil guide medium 2440 increases, and the contact area between the heating element 245 and the tobacco oil increases, thereby improving the efficiency of the heating element 245 in heating the tobacco oil. A large amount of smoke can be generated in a short time, increasing the amount of smoke in the user's first puff. In addition, by providing a collecting pipe to gather the generated smoke, a large amount of smoke can be achieved during the user's use, providing the user with a rich taste.
