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 in the prior art, e-liquid in electronic cigarettes comes into contact with the oil-guiding cotton in the finished core too early, which easily leads to oil leakage under external factors.

[0005] This utility model discloses an oil-core separation structure for electronic cigarettes, including a mouthpiece assembly and an oil cup assembly. The oil cup assembly includes an oil cup, an atomizing core assembly, and an oil-sealing elastic element. The atomizing core assembly and the oil-sealing elastic element are disposed inside the oil cup, with the oil-sealing elastic element sleeved on the atomizing core assembly. The atomizing core assembly has an oil guide hole, which the oil-sealing elastic element can block. The oil cup has a mounting part that cooperates with the oil-sealing elastic element, which can position the oil-sealing elastic element.

An oil-filling hole is provided at the upper end of the oil cup, and an oil plug that cooperates with the oil-filling hole is provided at the lower end of the oil-filling sealing elastic element. Furthermore, a guide connection hole that cooperates with the upper air passage hole is provided on the oil-filling sealing elastic element. A guide cylinder is provided extending from the guide connection hole toward the mouthpiece assembly. The upper end of the atomizing core assembly is placed in the guide cylinder, and the lower end of the mouthpiece air passage tube can be pressed into the guide cylinder. The guide cylinder can improve the sealing between the lower end of the mouthpiece air passage tube and the upper end of the atomizing core assembly.

[0011] This utility model is further improved by including an oil-filled sealing elastic element comprising an oil-filled sealing silicone and a mounting support plate disposed within the oil-filled sealing silicone. The mounting support plate can improve the strength of the oil-filled sealing silicone.

[0012] This utility model is further improved in that the diameter of the mouthpiece air passage tube gradually increases from bottom to top, the limiting part is a mouthpiece step set on the inner wall of the mouthpiece body, and the outer wall of the mouthpiece air passage tube is provided with a mouthpiece protrusion that cooperates with the mouthpiece step.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, this utility model discloses an oil-coil separation structure for electronic cigarettes, including a mouthpiece assembly 1 and an oil cup assembly 2. The oil cup assembly 2 includes an oil cup, an atomizing coil assembly, and an oil-sealing elastic element 25. The atomizing coil assembly and the oil-sealing elastic element 25 are disposed inside the oil cup, and the oil-sealing elastic element 25 is sleeved on the atomizing coil assembly. The atomizing coil assembly is provided with an oil guide hole 231, and the oil-sealing elastic element 25 can seal the oil guide hole 231. The oil cup is provided with a mounting part that cooperates with the oil-sealing elastic element 25, and the mounting part can seal the oil-sealing elastic element 25. The position is determined by the position of the oil cup. The upper and lower ends of the oil cup are respectively provided with an upper air passage hole 211 and a lower air passage hole 212. The two ends of the atomizing core assembly are slidably disposed in the upper air passage hole 211 and the lower air passage hole 212. The mouthpiece assembly 1 includes a mouthpiece body 11 and a mouthpiece air passage tube 12 disposed in the mouthpiece body 11. The mouthpiece body 11 is provided with a limiting part that restricts the downward movement range of the mouthpiece air passage tube 12. The mouthpiece air passage tube 12 can press down on the atomizing core assembly so that the oil sealing elastic element 25 is misaligned with the oil guide hole 231 to achieve oil core conduction.

[0025] By setting the oil-sealing elastic element 25, the oil guide hole 231 can be sealed before use. When it is needed, simply press the mouthpiece airway tube 12 to push the atomizing core assembly downward, so that the oil-sealing elastic element 25 is misaligned with the oil guide hole 231, and the e-liquid in the oil cup enters the atomizing core assembly for use. This effectively avoids oil leakage of electronic cigarettes before use, improves the user experience and the competitiveness of the product.

[0026] Both the upper airway hole 211 and the lower airway hole 212 are equipped with sealing silicone rings 213. The sealing silicone rings 213 can improve the sealing between the atomizer core assembly and the oil cup.

[0027] The oil cup includes an oil cup body 21 and an oil cup base 22. The upper end of the oil cup base 22 is provided with a connecting cylinder 221 that mates with the inner wall of the oil cup body 21. The mounting part is a positioning step provided on the upper end of the connecting cylinder 221. The outer side of the oil sealing elastic member 25 is provided with a positioning boss that mates with the positioning step. The oil sealing elastic member 25 is provided with an oil flow hole 251. The oil guide hole 231 allows the e-liquid to flow into the connecting cylinder 221. The lower air duct hole 212 is provided on the oil cup base 22.

[0028] The main purpose of the mounting section is to prevent the sealing elastic element 25 from moving when the atomizer coil assembly moves downwards. This design directly matches the outer contour shape of the sealing elastic element 25 with the cross-sectional shape of the inner wall of the oil cup, improving the stability of the sealing elastic element 25. This allows the oil flow hole 251 to guide the e-liquid to the connecting tube 221. Obviously, the shape of the sealing elastic element 25 and the presence or absence of the oil guide hole 231 are not unique; other structural methods can be used instead. The design of the mounting section can be... A protruding plate or boss is set on the inner wall of the oil cup. The area of ​​the oil-sealing elastic element 25 is smaller than the cross-sectional area of ​​the inner wall of the oil cup. The protruding plate or boss is set below the oil-sealing elastic element 25. The protruding plate or boss restricts the downward movement of the oil-sealing elastic element 25. E-liquid flows into the connecting tube 221 from the outside of the oil-sealing elastic element 25. When the atomizer core assembly moves downward, the oil guide hole 231 moves into the connecting tube 221, and the e-liquid in the connecting tube 221 enters the atomizer core assembly. After the e-liquid has completely entered the atomizer core assembly, it can be used. The same effect as the above solution can be achieved.

[0029] A connecting sealing ring 222 is fitted on the outside of the connecting cylinder 221. The sealing performance between the oil cup body 21 and the oil cup base 22 can be improved by setting the connecting sealing ring 222.

[0030] The oil-sealing elastic element 25 includes an oil-sealing silicone sleeve and an oil-sealing support plate 251 disposed inside the oil-sealing silicone sleeve. The oil-sealing support plate 251 can improve the strength of the oil-sealing silicone sleeve and prevent the oil-sealing silicone sleeve from deforming during installation, which could lead to improper assembly and affect the product's performance.

[0031] The oil core separation structure for electronic cigarettes also includes an oil filling and sealing elastic element 26. An oil filling hole is provided at the upper end of the oil cup, and an oil plug 261 that cooperates with the oil filling hole is provided at the lower end of the oil filling and sealing elastic element 26. A guide connection hole that cooperates with the upper air passage hole 211 is provided on the oil filling and sealing elastic element 26. A guide cylinder 262 is provided extending from the guide connection hole toward the mouthpiece assembly 1. The upper end of the atomizing core assembly is placed in the guide cylinder 262, and the lower end of the mouthpiece air passage tube 12 can be pressed into the guide cylinder 262.

[0032] By setting the guide tube 262, the sealing between the lower end of the mouthpiece air passage tube 12 and the upper end of the atomizing core assembly can be improved. After the atomizing core assembly moves down into place, the lower end of the mouthpiece air passage tube 12 is inserted into the guide tube 262, thus achieving a seal.

[0033] The oil-filled sealing elastic element 26 includes an oil-filled sealing silicone and an installation support plate 263 disposed within the oil-filled sealing silicone. The installation support plate 263 can improve the strength of the oil-filled sealing silicone and prevent deformation of the oil-filled sealing silicone during installation, which could lead to improper assembly and affect the product's performance.

[0034] The diameter of the mouthpiece air passage 12 gradually increases from bottom to top. The limiting part is a mouthpiece step set on the inner wall of the mouthpiece body 11, and the outer wall of the mouthpiece air passage 12 is provided with a mouthpiece protrusion that cooperates with the mouthpiece step.

[0035] By gradually increasing the pipe diameter from bottom to top, the friction between the lower end of the mouthpiece air passage 12 and the guide cylinder 262 is increased, thereby improving the stability of the mouthpiece air passage 12 position.

[0036] The atomizer core assembly includes a finished atomizer core 23 and an atomizer core bracket 24. The lower end of the finished atomizer core 23 passes through the lower air passage hole 212 and is fixedly mounted on the atomizer core bracket 24. A first limiting member is provided on the oil cup, and a second limiting member that cooperates with the first limiting member is provided on the atomizer core bracket 24.

[0037] By using the first and second limiting components together, the movement range of the finished atomizing core 23 can be effectively limited, preventing the finished atomizing core 23 from moving downwards beyond the range, causing the oil guide hole 231 to leave the oil cup, and the oil cup to be unable to supply oil.

[0038] The first limiting component is a guide hole 223 located at the lower end of the oil cup, and the second limiting component is a guide block 241 located on the outside of the atomizing core bracket 24, with the guide block 241 located in the guide hole 223.

[0039] As can be seen from the above, the beneficial effects of this utility model are: by adopting its structure, it can effectively solve the problem in the prior art that e-liquid in electronic cigarettes comes into contact with the oil-guiding cotton in the finished core too early, which easily leads to oil leakage under external factors. By using this product structure, the setting of the oil-sealing elastic element 25 can seal the oil-guiding hole 231 before use. When it is needed, simply press the mouthpiece airway tube 12 to push the atomizing core assembly downward, so that the oil-sealing elastic element 25 is misaligned with the oil-guiding hole 231, and the e-liquid in the oil cup enters the atomizing core assembly for use. This effectively avoids the situation of e-cigarette leakage before use, improves the user experience and the competitiveness of the product.
