[0025] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0026] like Figures 1 to 3 As shown, this embodiment discloses an oil-filled atomizing device 10, which includes a nozzle 11 and an atomizing assembly 20. The atomizing assembly 20 includes an atomizing rod 21 and an outer sleeve 22. The outer sleeve 22 is sleeved on the outside of the atomizing rod 21. Both ends of the outer sleeve 22 are sealed with the atomizing rod 21 through a sealing member 23. The outer sleeve 22 cooperates with the sealing member 23 to form a first cavity 24 for storing oil between the atomizing rod 21; the sealing member 23 includes a top sealing silicone 231, and the top sealing member 23 is provided with a sealing member 232. One end of the lower sealing silicone 231 is sealed and connected to the atomizer assembly 20, and the other end of the top sealing silicone 231 is detachably connected to the suction nozzle 11. The top sealing silicone 231 is provided with an oil filling position 233. The suction nozzle 11 includes a suction nozzle channel 12 and an oil filling channel 13 that are independent of each other. The suction nozzle channel 12 cooperates with the atomizer rod 21, and the oil filling channel 13 cooperates with the oil filling position 233. When filling oil, the oil filling needle 15 is operated to pierce the silicone at the oil filling position 233 into the first cavity 24 and then inject oil.

[0027] By setting an oil filling position 233 on the top sealing silicone 231, the oil filling operation does not require covering the suction nozzle 11 or the lid, and the suction nozzle 11 and the atomizer rod 21 are split, providing 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; and the oil filling channel 13 is matched with the oil filling position 233. This structural method provides simple oil filling and reduces costs. During the oil filling process, there is no need to consider the oil filling time cycle, which reduces the time and labor cost of covering the lid or the suction nozzle 11, completely solves the oil leakage risk of the oil filling method in the prior art, provides customers with a simple, easy-to-operate product without the risk of oil leakage, and also reduces the assembly cost after oil filling; and the outer sleeve 22 cooperates with the seal 23 to form a first cavity 24 for storing oil between the atomizer rod 21, effectively reducing the number of assembly times, ensuring the consistency of the assembly process, making assembly simple, and being able to effectively utilize the space between the atomizer rod 21 and the outer sleeve 22. There is no need to set up a separate oil storage tank, making the overall volume of the atomizer device 10 more compact.

[0028] Among them, sunken grooves are provided on both sides of the oil filling position 233, so that the silicone thickness of the oil filling position 233 is less than half the thickness of the top sealing silicone 231, and the outer sleeve 22 is made of glass. Since glass not only has good transparency but also has stable chemical properties, it will not chemically react with the oil in the first cavity 24, and can facilitate the user to observe the remaining amount of tobacco oil in the oil storage tank; optionally, the suction nozzle 11 and the atomizer rod 21 are integrally formed.

[0029] Among them, the atomizing rod 21 includes an atomizing module 25 and a central channel 26, the nozzle channel 12 is connected to one end of the central channel 26, the atomizing module 25 is arranged at the other end of the central channel 26, the atomizing module 25 includes a heating core 251 and oil-absorbing cotton 252, the oil-absorbing cotton 252 is arranged on the side wall of the central channel 26, the heating core 251 is arranged on the oil-absorbing cotton 252, the oil-absorbing cotton 252 can effectively prevent the oil from quickly entering the heating core 251, so as to well control the atomizing effect; the central channel 26 is provided with an oil inlet hole 261 at the position corresponding to the oil-absorbing cotton 252, and the oil inlet hole 261 is used to inject the first air into the oil-absorbing cotton 252. The oil in the cavity 24 is guided to the oil-absorbing cotton 252 and is atomized by the heating core 251 and then discharged through the central channel 26. When the user inhales through the suction nozzle 11, the central channel 26 forms a certain negative pressure so that the oil is evenly adsorbed on the oil-absorbing cotton 252. The heating core 251 works to atomize the oil that has penetrated into the oil-absorbing cotton 252 and discharges it through the central channel 26 to be inhaled by the user; an oleophobic layer 213 is provided on the outer surface of the atomizing rod 21 and the inner surface of the outer sleeve 22, so that the oil will not stick to the atomizing rod 21 and the outer sleeve 22, thereby solving the problem of unclean oil extraction of the atomizing equipment and saving user costs.

[0030] When filling oil, the atomizing device 10 is placed upside down on the workbench fixture. The oil filling needle 15 is directly inserted into any oil filling channel 13 on the suction nozzle 11, piercing the top sealing silicone 231 at the oil filling position 233 until the required liquid is injected into the oil cup body. The injected liquid capacity is 1.0ML / 0.5ML (the total height of the mass production capacity product is different). After the oil filling is completed, the needle can be directly pulled out. The silicone will reset to block the needle hole to form a sealed state. Since the entire oil cup is completely sealed, it needs to be turned upside down when filling oil, because a large amount of air needs to be removed from the micropores of the heating core when injecting liquid. After filling with oil, a vacuum state is formed in the oil cup to avoid the risk of oil leakage.

[0031] Among them, the atomization device 10 also includes a connecting component 30 for power supply installation, the connecting component 30 includes a fixing frame 31, the sealing member 23 includes a bottom sealing silicone 232, one end of the fixing frame 31 is sleeved on the end of the atomization rod 21, the bottom sealing silicone 232 is sleeved on the outside of the fixing frame 31 and is fixed by the outer sleeve 22. The bottom sealing silicone 232 is pressed by the outer sleeve 22 so that the fixing frame 31 is stably sleeved on the atomization rod 21, thereby ensuring a very good sealing effect; the other end of the connecting component 30 is provided with a thread for connecting the battery, making the installation and replacement of the battery more convenient and simple; among them, an insulating silicone 28 is provided between the heating core 251 and the inner wall of the atomization rod 21, the heating core 251 includes an electrode 253, the electrode 253 extends along the inner wall of the fixing frame 31, and an insulating silicone 27 is provided between the fixing frame 31 and the electrode 253. The setting of the insulating silicone 27 can effectively avoid the risk of leakage and better ensure safety of use.

[0032] Among them, a plastic ring 32 is provided on the outside of the connecting component 30, and the plastic ring 32 is sleeved on the outside of the fixing frame 31. The setting of the plastic ring 32 can effectively fasten the connecting component 30, making the installation of the connecting component 30 more stable. At the same time, the color and material of the plastic ring 32 can be replaced and customized, which also provides optionality in the process of manufacturing the appearance parts.

[0033] Among them, the inner diameter of the central channel 26 gradually or in stages decreases from one end where the atomization module 25 is set to the end where the suction nozzle 11 is set, so that the inner diameter of the central channel 26 at the outlet will be smaller, effectively increasing the flow rate at the suction nozzle 11 and having a better taste; optionally, the atomization rod 21 includes an atomization section 211 and a suction nozzle section 212, and the inner diameter of the central channel 26 in the atomization section 211 is larger than the inner diameter of the central channel 26 in the suction nozzle section 212.

[0034] Among them, a sealing position 14 is provided on the suction nozzle 11, and a limiting protrusion 234 that cooperates with the sealing position 14 is provided on the top sealing silicone 231. The cooperation between the limiting protrusion 234 and the sealing position 14 can effectively limit and fix the suction nozzle 11, which also reduces the assembly, production and packaging costs in the early stage and improves efficiency in design.

[0035] Compared with the oiling method of ordinary products, the above-mentioned oiling structure reduces the customer's oiling cost, mainly because it reduces the action of covering the suction nozzle 11, solves the common oil leakage problem in the market, and improves the operability of oiling. It also provides optionality in the process of manufacturing the appearance of the suction nozzle 11. The suction nozzle 11 and the center rod are split into a structure, and the color and material of the suction nozzle 11 are optional. The installation and disassembly of the suction nozzle 11 will not affect the oiling operation and sealing performance of the atomizing equipment 10; and this solution can also reduce the assembly, production, and packaging costs in the early stage, and improve efficiency in design.

[0036] 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, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all of these should be considered to fall within the scope of protection of the present invention.
