Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an oil-core separation structure for electronic cigarettes. Background Technology

[0002] An electronic cigarette is an electronic device that mimics the function of a traditional cigarette. It vaporizes a liquid containing nicotine using an atomizer, allowing the user to inhale the vapor. Electronic cigarettes typically consist of a cartridge and a device. The cartridge contains a vaporizer, which is powered by a battery within the device. This vaporizer transforms the liquid nicotine in the cartridge into a vapor, giving the user a sensation similar to smoking, allowing them to "exhale clouds of smoke."

[0003] With the expansion of the e-cigarette market and the innovative development of industry technology, the internal structure and component connection methods of e-cigarettes have become more diversified. In the traditional e-cigarette filling process, the e-liquid is filled after the finished coil is assembled into a finished or semi-finished product. At this time, the e-liquid can directly contact the wicking cotton inside the finished coil. Before use, due to factors such as oil pressure and vibration, e-liquid is prone to leaking out of the atomizer during storage and transportation, resulting in a bad user experience. Utility Model Content

[0004] To address the problems in the prior art, this utility model provides an oil-core separation structure for electronic cigarettes, which solves the problem that e-liquid in electronic cigarettes comes into contact with the atomizing core assembly too early, making it prone to leakage under external factors.

[0005] This utility model discloses an oil-core separation structure for electronic cigarettes, comprising a cartridge body, an atomizing core assembly, an oil-sealing elastic movable component, and a lower oil-sealing assembly. The lower oil-sealing assembly has an atomizing mounting position that cooperates with the atomizing core assembly. The lower end of the atomizing core assembly is fixedly installed in the atomizing mounting position, and the atomizing core assembly has an oil guide hole. An oil storage cavity is provided inside the cartridge body, and the lower oil-sealing assembly can seal the oil storage cavity. A mouthpiece is provided on the cartridge body, and the mouthpiece extends into the oil storage cavity to provide a mouthpiece channel. The oil-sealing elastic movable component includes a pull rod and a sleeve. The sleeve is sleeved on the upper end of the atomizing core assembly and can seal the oil guide hole. The upper ends of both the pull rod and the sleeve are located in the mouthpiece channel, and a movement limiting part is provided on the outside of the sleeve to limit the upward movement distance of the sleeve. The pull rod and the sleeve are connected by a connecting film, and the pull rod can pull upward to make the sleeve move away from the oil guide hole.

[0006] This utility model is further improved by providing an upper sealing part on the outside of the sleeve, which can improve the sealing between the sleeve and the suction nozzle channel.

[0007] The present invention is further improved by the upper sealing part being a sealing protrusion ring located at the upper end of the sleeve.

[0008] This utility model is further improved by providing a guide bevel at the lower end of the suction nozzle channel that cooperates with the sealing protrusion ring.

[0009] The present invention is further improved by the motion limiting part being a limiting boss provided on the outside of the sleeve, the diameter of which is larger than that of the suction nozzle channel.

[0010] This utility model is further improved by providing oil-absorbing cotton inside the suction nozzle channel.

[0011] This utility model is further improved by providing an air passage hole on the sleeve, and the connecting membrane can seal the air passage hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides an oil-coil separation structure for electronic cigarettes. This structure effectively solves the problem of premature contact between e-liquid and the atomizing core assembly in existing electronic cigarettes, which easily leads to oil leakage under external factors. By setting up a sealing elastic movable part, the oil guide hole can be sealed before use. During use, simply pull the lever outwards, moving the sleeve away from the oil guide hole, allowing e-liquid to enter the atomizing core assembly. Furthermore, the movement limit part restricts the sleeve movement to a designated position, causing the connecting membrane to rupture and the lever to be removed, allowing normal use. This effectively avoids oil leakage before use, improving the user experience and product competitiveness. Attached Figure Description
