[0054] Please refer to Figure 7 , Figure 7 which is Figure 2Explosion schematic diagram of the heating core 240 shown. The heating core 240 includes a gas collecting cover 241, a bracket 2412, an oil guiding assembly 244, and a plurality of heating elements 245. The gas collecting cover 241 includes an end cover 242 and a manifold 243. Exemplarily, the oil guiding assembly 244 may include an oil guiding medium 2440 and a fixing base 2411.

[0055] It should be noted that 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 atomizing 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.

[0056] In some possible embodiments, please refer to Figure 8 , Figure 8 is Figure 7 structural schematic diagram of the bracket 2412 and the fixing base 2411 shown. Among them, Figure 8 the angle between the bracket 2412 and the fixing base 2411 shown is different from Figure 7 the angle between the bracket 2412 and the fixing base 2411 shown. The bracket 2412 is connected to the outer periphery of the fixing base 2411. That is to say, the fixing base 2411 is fixedly arranged in the ventilation hole 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 back to back along the axial direction of the heating core 240. The bracket 2412 is provided with a ventilation hole 2415. The ventilation hole 2415 penetrates through the first end face 2413 and the second end face 2414.

[0057] The fixing base 2411 is provided with a plurality of mounting holes 2417. Exemplarily, a communication hole (not shown in the figure) may be provided between two adjacent mounting holes 2417, and the communication hole is used to communicate two adjacent mounting holes 2417. The mounting holes 2417 penetrate through the fixing base 2411 along the axial direction of the fixing base 2411. It can be understood that the communication hole can allow the e-liquid in two adjacent mounting holes 2417 to pass through, so that the e-liquid can be evenly distributed on a plurality of oil guiding media.

[0058] In some possible embodiments, a plurality of mounting holes 2417 are arranged along the circumferential direction of the heating core 240. There is a gap between adjacent mounting holes 2417. Exemplarily, the number of mounting holes 2417 is three, and the three mounting holes 2417 are arranged in a triangular pattern.

[0059] The bracket 2412 is provided with a limiting groove 2418. The limiting groove 2418 penetrates through the bracket 2412 along the radial direction of the bracket 2412 and penetrates through the first end face 2413 of the bracket 2412. Exemplarily, the number of limiting grooves 2418 is three, and the three limiting grooves 2418 are arranged at intervals along the circumferential direction of the bracket 2412. Exemplarily, the bracket 2412 and the fixed seat 2411 may be integrally formed. The structures of the bracket 2412 and the fixed seat 2411 may be made of metal or plastic. Among them, when the bracket 2412 and the fixed seat 2411 are made of metal, the structural stability of the bracket 2412 and the fixed seat 2411 can be increased, and the possibility of deformation of the fixed seat 2411 and the bracket 2412 can be reduced. When the bracket 2412 and the fixed seat 2411 are made of plastic, the integral structure of the bracket 2412 and the fixed seat 2411 is easier to form. Exemplarily, the bracket 2412 and the fixed seat 2411 may also be two separate parts, assembled to form Figure 8 the structure shown.

[0060] The bracket 2412 is connected to the outer periphery of the fixed seat 2411. The axial direction of the bracket 2412 can be perpendicular to the first end face 2413 and the second end face 2414. The bracket 2412 is further provided with a first connecting body 2419, and the first connecting body 2419 protrudes relative to the second end face 2414. The first connecting body 2419 may be annular.

[0061] On one side of the first end face 2413 of the bracket 2412, a second connecting body 2410 protrudes relative to the fixed seat 2411. The second connecting body 2410 surrounds the outer periphery of the plurality of mounting holes 2417.

[0062] The limiting groove 2418 communicates with the mounting hole 2417. Exemplarily, each limiting groove 2418 communicates with one mounting hole 2417. The two ends of the bracket 2412 along the circumferential direction may protrude relative to the fixed seat 2411. The part of the bracket 2412 between the two limiting grooves 2418 may protrude relative to the fixed seat 2411. The protruding part is the second connecting body 2410. Exemplarily, the parts of the bracket 2412 between the three limiting grooves 2418 all protrude relative to the fixed seat 2411. That is, the number of the second connecting bodies 2410 may be three.

[0063] Please refer to Figure 9 , Figure 9 which is Figure 7Schematic structural diagram of the gas collecting cover 241 shown. The end cover 242 has a current collecting cavity 2421. The current collecting cavity 2421 penetrates the end cover 242 along the axial direction of the end cover 242. Along the axial direction of the end cover 242, the radial dimension of the current collecting cavity 2421 gradually decreases.

[0064] The end cover 242 is connected to the second connecting body 2410 of the bracket 2412. The end of the end cover 242 with a larger end face area faces the fixed seat 2411. The opening on the side of the current collecting cavity 2421 facing the fixed seat 2411 covers all the mounting holes 2417, so that the current collecting cavity 2421 is communicated with the mounting holes 2417. The radial dimension of the current collecting cavity 2421 gradually decreases along the direction in which the end cover 242 is away from the second end face 2414.

[0065] It can be understood that the shape of the end cover 242 is similar to a funnel shape. When the smoke passing through the fixed seat 2411 flows through the end cover 242, the airflow of the smoke will be collected, forming a smoke airflow with a smaller cross-sectional area. The smoke airflow can efficiently pass through the cigarette holder 222 and enter the user's mouth.

[0066] The second connecting body 2410 of the bracket 2412 is connected to the electrode mounting portion 212 of the base 210. Specifically, the second connecting body 2410 can be located in the connecting groove 2121 of the electrode mounting portion 212. The groove wall of the connecting groove 2121 can limit the second connecting body 2410. Each second connecting body 2410 corresponds to a connecting groove 2121. Thus, the relative position of the bracket 2412 and the base 210 in the circumferential direction of the heating core 240 is fixed.

[0067] One end of the current collecting pipe 243 is connected to the side of the end cover 242 facing away from the fixed seat 2411. The current collecting pipe 243 is communicated with the current collecting cavity 2421. The other end of the current collecting pipe 243 is connected to the first end of the cigarette holder 222. In the axial direction of the current collecting pipe 243, the end of the current collecting pipe 243 facing away from the end cover 242 abuts against the groove wall of the guiding groove 2223 of the first section 2221. The diameter of the pipe inside the current collecting pipe 243 can be the same as the diameter of the first section 2221 of the cigarette holder 222. The inner diameter of the pipe inside the current collecting pipe 243 is smaller than the inner diameter of the bracket 2412, and the current collecting pipe 243 extends along the axial direction of the bracket 2412.

[0068] Please refer to Figure 7 again. The oil guiding assembly 244 is provided with a plurality of atomization channels 2441, and the plurality of atomization channels 2441 are arranged along the circumferential direction of the heating core 240. Each atomization channel 2441 penetrates the oil guiding assembly 244 along the axial direction of the heating core 240. In a possible implementation manner, the oil guiding assembly 244 includes an oil guiding medium 2440, and the oil guiding medium 2440 is provided with a plurality of atomization channels 2441. At least a part of the oil guiding assembly 244 is located in the ventilation hole 2415 of the bracket 2412.

[0069] In another possible implementation, the oil guiding assembly 244 includes a plurality of oil guiding media 2440 and the fixing base 2411 as described above. The plurality of oil guiding media 2440 are arranged along the circumferential direction of the heating core 240. Each oil guiding media 2440 includes an oil guiding body 2442 and a limiting portion 2443. The limiting portion 2443 is connected to the outer periphery of the oil guiding body 2442. One oil guiding media 2440 is provided with one atomization channel 2441. The atomization channel 2441 penetrates through the oil guiding body 2442 along the axial direction of the oil guiding media 2440. Please refer to Figure 10 , Figure 10 is Figure 7 the assembly schematic diagram of the heating core 240 shown in the figure. The oil guiding body 2442 is located in the mounting hole 2417 of the fixing base 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 peripheral surface of the bracket 2412, or the limiting portion 2443 is flush with the outer peripheral surface of the bracket 2412.

[0070] It can be understood that when the limiting portion 2443 protrudes relative to the outer peripheral surface of the bracket 2412 or is flush with the outer peripheral surface. After 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 guiding media 2440. The e-liquid can reach the oil guiding body 2442 from the oil storage cotton 250 through the limiting portion 2443. After the oil guiding body 2442 is heated, the e-liquid can be atomized into smoke, and the smoke can flow through the mounting hole 2417 of the fixing base 2411 to the current collecting cavity 2421 and flow out through the current collecting pipe 243 to the cigarette mouth 222.

[0071] The number of the heating elements 245 is multiple. One end of each heating element 245 is located in one atomization channel 2441 and contacts the hole wall of one atomization channel 2441, and the other end of each heating element 245 protrudes relative to the oil guiding assembly 244.

[0072] Specifically, please refer to Figure 11 , Figure 11 is Figure 7 the structural schematic diagram of the heating element 245 shown in the figure. The heating element 245 includes a heating body 2451, a first pin 2452 and a second pin 2453. The heating body 2451 can be a bent plate shape. The heating body 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 body 2451. The first pin 2452 and the second pin 2453 can extend in the same direction.

[0073] Each heating element 2451 is located within an atomization channel 2441. The heating element 2451 is in contact with the pore wall of the atomization channel 2441. The first pin 2452 and the second pin 2453 extend out from within the atomization channel 2441. The first pin 2452 and the second pin 2453 extend in the direction of 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. Exemplarily, the first pin 2452 is the positive pin and the first electrode 231 is the positive electrode. The second pin 2453 is the negative pin and the second electrode 232 is the negative electrode. Alternatively, the first pin 2452 is the negative pin and the first electrode 231 is the negative electrode. The second pin 2453 is the positive pin and the second electrode 232 is the positive electrode.

[0074] The oil storage cotton 250 is located within the accommodation space. The size of the oil guiding medium 2440 can be set using the size of the oil sump 220. The oil storage cotton 250 is disposed around the heating core 240. Exemplarily, 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 is in contact with the limiting body of the oil guiding medium 2440.

[0075] It can be understood that the e-liquid can be stored in the oil storage cotton 250. When the user is using the atomization device 1000. The main unit 100 is connected to the atomizer 200. Thus, the power supply in the main unit 100 can supply power to the atomizer 200. The current can flow through the first electrode 231, the first pin 2452, the heating element 2451, the second pin 2453, and the second electrode 232 in sequence and then flow to the negative pole of the power supply. After the heating element 2451 has current flowing through it, it will get hot, thereby heating the oil guiding body 2442. The e-liquid located within the oil guiding body 2442 is heated and atomized.

[0076] During the process of the user sucking on the atomization device 1000, the air flow will flow in through the air inlet hole 2311 of the first electrode 231 and pass through the oil guiding body 2442. When the air flow passes through the oil guiding body 2442, it will carry out the atomized e-liquid. The gas carrying the smoke will pass through the current collecting cavity 2421, the current collecting pipe 243, and the mouthpiece 222 in sequence and reach the user's mouth, thereby completing the sucking process.

[0077] The atomization device 1000 provided by the embodiment of the present application includes a plurality of heating elements 245. After the host 100 powers the atomizer 200, the plurality of heating elements 245 can be heated simultaneously or more than one heating element 245 can be heated simultaneously to jointly heat the oil guiding assembly 244. Since the number of the heating elements 245 increases, the contact area between the heating elements 245 and the oil guiding medium 2440 becomes larger, and the contact area between the heating elements 245 and the e-liquid increases, thereby improving the efficiency of the heating elements 245 in heating the e-liquid. A large amount of smoke can be generated in a short time, increasing the amount of smoke in the user's first puff. And by setting a manifold to gather the generated smoke, the effect of a large amount of smoke is achieved during the user's use, providing the user with a rich taste.
