[0024] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0025] like Figures 1 to 3As shown, this embodiment discloses an atomizing device 10 without a center rod, the atomizing device 10 includes a nozzle 11, an atomizing assembly 20 and a connecting assembly 30, the nozzle 11 and the connecting assembly 30 are respectively connected to the two ends of the atomizing assembly 20, the atomizing assembly 20 includes a cylindrical tube 21 and an atomizing portion 22, a first partition 213 extending in the axial direction is provided in the cylindrical tube 21, the first partition 213 and the inner wall of the cylindrical tube 21 form two independent first channels 211 and second channels 212, the top of the cylindrical tube 21 is provided with a top sealing silicone 23, and the atomizing portion 22 is provided in the first channel 211. At the bottom end, the inner wall of the first channel 211 cooperates with the top sealing silicone 23 and the atomizing part 22 to form a first cavity 214 for storing oil. The smoke generated by the atomizing part 22 when working enters the suction nozzle 11 through the second channel 212; the suction nozzle 11 is provided with a suction channel 111, and the suction channel 111 is in air communication with the second channel 212. The top sealing silicone 23 is provided with an oil filling position 231, and the suction channel 111 is located above the oil filling position 231. When filling oil, the oil filling needle 40 is operated to enter from the suction channel 111 and pierce the silicone of the oil filling position 231 into the first cavity 214 to inject oil.

[0026] By passing the oil injection needle 40 from the suction channel 111 into the first cavity 214 for oil injection, not only can the oil injection operation be performed without disassembling the suction nozzle 11, making the oil injection operation more convenient and simple, but also reducing the setting of unnecessary special oil injection structures, effectively reducing the overall volume of the atomizing device 10; and the first partition 213 divides the space in the cylindrical tube 21 into two mutually independent first channels 211 and second channels 212. When in use, different channels are distinguished according to different users, reducing the number of related pipelines such as the center rod, so that pipelines for various purposes are concentrated in the cylindrical tube 21. The above-mentioned structure forms an integrated setting, further optimizing the indirectness of the overall layout of the atomizing device 10, improving the user experience and assembly difficulty; at the same time, the closed oil filling method using the top sealing silicone 23 completely solves the oil leakage phenomenon during the oil filling process, and provides customers with a simple and cost-effective solution in terms of operation after oil filling. During the oil filling process, there is no need to consider the oil filling time period, which reduces the time and labor of covering the suction nozzle 11, and completely solves the oil leakage risk of the old solution, providing customers with a simple, easy-to-operate atomizing device 10 product without the risk of oil leakage, while also reducing the assembly cost after oil filling.

[0027] Among them, the bottom end of the cylindrical tube 21 is provided with a bottom sealing silicone 24, and the bottom of the first channel 211 is radially provided with a second partition 215, which can effectively separate the first cavity and the second cavity to better avoid oil leakage; the inner wall of the first channel 211 and the bottom sealing silicone 24 and the second partition 215 form a second cavity 217 for installing the atomization part 22, and the main functional components of the atomization device 10 are concentrated on the cylindrical tube 21, further optimizing the utilization of the space of the cylindrical tube 21, so that the overall volume of the atomization device 10 is optimized, effectively reducing the number of parts, further reducing the cost of the atomization device 10 and the assembly workload; the second cavity 217 is connected to the second channel 212 in an air path, and the smoke generated in the second cavity 217 when the atomization part 22 is working enters the nozzle 11 channel through the second channel 212, effectively improving the taste compared with the product with a center rod.

[0028] Among them, the atomization part 22 includes a heating core 221 and a thermal insulation silicone 222. The thermal insulation silicone 222 can not only effectively play a role of heat insulation, but also play a very good sealing role, ensuring that the oil in the first cavity 214 will not leak, and better ensuring the service life of the atomization device 10; an oil inlet hole 216 is provided on the second partition plate 215, and the thermal insulation silicone 222 is fixed on the inner wall of the second cavity 217. The heating core 221 is embedded in the thermal insulation silicone 222. A groove 223 is provided on the heating core 221. The oil inlet hole 216 is connected to the groove 223. The oil in the first cavity 214 enters the groove 223 of the heating core 221 through the oil inlet hole 216. The setting of the groove 223 can further increase the surface area of contact between the oil and the heating core, so that the atomization effect is better, thereby ensuring a better user experience.

[0029] Among them, the connection component 30 includes a fixing frame 31, an electrode 32 and an insulating silicone 33. The fixing frame 31 is mounted on the end of the cylindrical tube 21, and the electrode 32 is electrically connected to the heating core 221. The insulating silicone 33 is arranged between the electrode 32 and the fixing frame 31 and clamps the electrode 32. The insulating silicone 33 not only provides good insulation and leakage prevention, but also effectively limits the fixing frame 31 and the electrode 32, making the installation of the connection component 30 more stable. The connection component 30 includes a steel ring 34, which is mounted on the fixing frame 31. The steel ring 34 is provided with a coating 35. The setting of the coating 35 provides users with a variety of choices in material color, which can be customized to suit the preferences of different groups and keep up with the changing trends of human society.

[0030] Among them, the suction channel 111 is a linear channel, and a sunken groove 232 is provided on the oil filling position 231. The suction channel 111 and the sunken groove 232 are arranged coaxially, so that the oil filling needle 40 can be inserted into the first cavity 214 more conveniently and quickly. During the oil filling process, there is no need to consider the oil filling time cycle, which reduces the time and labor of covering the suction nozzle 11, completely solves the oil leakage risk of the existing atomizing device 10, and provides customers with a simple, easy-to-operate and oil-free atomizing device 10 product, while also reducing the assembly cost after oil filling. A limiting groove 112 is provided on the inner side of the suction nozzle 11, and a limiting ring groove 218 is provided on the outer side of the cylindrical tube 21. A fixing protrusion 219 is provided on the limiting ring groove 218. After the limiting groove 112 is matched with the fixing protrusion 219 through the limiting ring groove 218, the outer wall of the suction nozzle 11 is flush with the outer wall of the cylindrical tube 21, making the appearance of the atomizing device 10 more simple and beautiful, further improving the comfort of holding during use.

[0031] Among them, an oleophobic layer 25 is provided on the inner wall of the first cavity 214, so that the oil will not stick to the inner wall of the first cavity 214, which can make the oil extraction of the atomizing device 10 cleaner, further reduce the waste of oil, and save user costs.

[0032] The cylindrical tube 21 is a cylindrical tube 21, and the first partition 213 is a flat plate. The length of the first partition 213 is less than or equal to the length of the cylindrical tube 21. The first partition 213 is offset from the axis of the cylindrical tube 21. The width of the first partition 213 is less than the inner diameter of the cylindrical tube 21, which can ensure a larger volume of the first cavity 214, allowing the atomizing device 10 to accommodate more oil. The cylindrical tube 21 is made of a transparent material in an integral molding. The integral molding configuration is more convenient for manufacturing and production, and can also ensure better sealing performance. The transparent material can be selected from glass or plastic.

[0033] When performing the oil filling operation, the atomizing device 10 is placed on the workbench fixture, and the oil filling needle 40 is directly inserted into the suction channel 111, piercing the oil filling position 231 of the top sealing silicone 23 until the required oil is injected into the first cavity 214. Since the silicone is an elastic material, the pierced hole will automatically close and seal when the oil filling needle 40 is pulled out. The injected liquid capacity is 1.0ML / 2.0ML. After the oil filling is completed, the needle head of the oil filling needle 40 can be directly pulled out. Since the entire first cavity 214 is in a completely sealed state, it needs to be turned upside down when filling the oil, because a large amount of air needs to be removed from the micropores of the heating core 221 when injecting the liquid. After filling the oil, a vacuum state is formed in the oil cup to avoid the risk of oil leakage. Compared with the oil filling method of ordinary products, the oil filling structure of this atomizer device 10 reduces the customer's oil filling cost, mainly by covering the cigarette mouthpiece, while simultaneously improving the product's usage effect and taste experience, solving the common oil leakage problem in the market and improving the operability of oil filling; it also reduces the assembly, production, and packaging costs in the early stage and improves efficiency in design.

[0034] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
