Description

Technical Field

[0001] This application relates to the field of electronic cigarette technology, and in particular to a high-capacity, leak-proof electronic cigarette. Background Technology

[0002] Currently, existing e-cigarettes, in order to prolong the vaping time, are designed with a large-volume oil chamber to hold e-liquid. Because the oil chamber is large and holds a lot of oil, and the oil inlet is usually located at the bottom of the oil chamber to feed oil into the suction device for heating and atomization by the heating element, the oil inlet is subjected to the greatest oil pressure. Under high oil pressure, the suction device will become oversaturated and drip oil will be produced. These dripping e-liquids will flow out from the airway, causing e-cigarette leakage. Utility Model Content

[0003] The purpose of this application is to provide a large-capacity, leak-proof electronic cigarette, which solves the problem of leakage caused by the large volume and high oil capacity of the oil chamber in existing large-capacity electronic cigarettes, where the oil inlet is located at the bottom of the oil chamber and is subject to high oil pressure.

The space between the outer wall of the smoke exhaust pipe and the isolation tube and the inner wall of the upper oil tank serves as the main oil chamber. A sealing ring is provided between the outer wall of the smoke exhaust pipe and the inner wall of the isolation tube.

[0009] In one embodiment, the main body further includes an oil sealing component and a bottom shell. The oil sealing component is also disposed inside the bottom opening of the upper oil chamber, and the outer wall of the oil sealing component abuts against the inner wall of the upper oil chamber. The bottom shell is sleeved on the bottom end of the upper oil chamber, and an insertion port is opened at the bottom end of the bottom shell.

The conduit is located at the top of the lower oil chamber, and the oil guiding channel corresponds to and communicates with the auxiliary oil chamber. The conduit is inserted into the second channel and punctures the diaphragm, extending from the first channel into the main oil chamber, so that the main oil chamber corresponds to and communicates with the oil guiding channel. The top of the lower oil chamber is also provided with an atomizing hood, which is inserted into the isolation tube through the insertion port. The atomizing chamber is formed inside the atomizing hood, and the top wall of the atomizing hood serves as the top wall of the atomizing chamber. A vent is provided on the top wall of the atomizing hood, which communicates with the exhaust channel and the atomizing chamber.

[0011] In one embodiment, the lower end of the atomizing cover extends into the secondary oil chamber. The oil-absorbing element and the heating element are disposed within the atomizing cover, and the oil-absorbing element fills the atomizing chamber.

[0014] The large-capacity leak-proof e-cigarette of this application has the following beneficial effects: The large-capacity leak-proof e-cigarette of this application introduces e-liquid from the large-volume main e-liquid chamber into the small-volume auxiliary e-liquid chamber through the e-liquid guide channel to reduce the e-liquid pressure. Then, the e-liquid enters the suction device through the e-liquid inlet to be heated and atomized by the heating core. This prevents the existing large-capacity e-cigarettes from having only one e-liquid chamber. The large volume of the e-liquid chamber and the large e-liquid pressure caused by the e-liquid inlet being located directly at the bottom of the e-liquid chamber can lead to oversaturation of the suction device and dripping of e-liquid from the air passage, thus causing e-liquid leakage.

It should be noted that, as long as there is no conflict, the various embodiments and features in each embodiment of this application can be combined with each other, and the resulting technical solutions are all within the protection scope of this application.

[0017] It should be noted that the specification of this application contains a large number of technical features distributed across various technical solutions. Listing all possible combinations of technical features (i.e., technical solutions) would make the specification overly lengthy. To avoid this problem, the various technical features claimed in the above-described utility model content, the various technical features claimed in the following embodiments and examples, and the various technical features claimed in the accompanying drawings can be freely combined to form various new technical solutions (all of which are considered to have been described in this specification), unless such a combination of technical features is technically infeasible. For example, in one example, feature A+B+C is claimed, and in another example, feature A+B+D+E is claimed. Features C and D are equivalent technical means that serve the same function, and technically only one needs to be used; they cannot be used simultaneously. Feature E can be technically combined with feature C. Therefore, the solution A+B+C+D should not be considered as having been described because it is technically infeasible, while the solution A+B+C+E should be considered as having been described.

[0018] In this application, the terms "upper", "lower", "side", "top", "bottom", "inner", "outer", etc., are based on the orientation or positional relationship shown in the accompanying drawings and are only for the purpose of describing and understanding the technology of this application, and are not intended to limit the device or component to have a specific orientation or to be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0019] like Figure 1-5 As shown, this application provides a large-capacity leak-proof electronic cigarette, including a main body 15. The main body 15 has a main oil chamber 101 and a secondary oil chamber 601 that are isolated from each other, as well as an atomizing chamber 606. The volume of the main oil chamber 101 is larger than that of the secondary oil chamber 601. The main oil chamber 101 stores e-liquid. The main oil chamber 101 has a conduit 602 corresponding to the secondary oil chamber 601. The conduit 602 has an oil guiding channel 604 for guiding the e-liquid in the main oil chamber 101 into the secondary oil chamber 601. The lower end of the atomizing chamber 606 is located in the secondary oil chamber 601. The lower end of the atomizing chamber 606 is provided with a heating core 8 and an oil suction component 7 wrapped around the heating core 8. The cavity wall corresponding to the lower end of the atomizing chamber 606 has an oil inlet hole 607 that corresponds to and communicates with the secondary oil chamber 601. The oil inlet hole 607 also corresponds to the oil suction component 7. The main body 15 also has a power supply assembly 1501 for supplying power to the heating core 8. It should be noted that the e-liquid in the large-volume main oil chamber 101 is introduced into the small-volume secondary oil chamber 601 through the oil guide channel 604 to reduce the oil pressure. Then, the e-liquid enters the suction component 7 through the oil inlet 607 to be heated and atomized by the heating core 8. This prevents the existing large-capacity electronic cigarettes from having only one oil chamber. The oil chamber has a large volume and a large oil capacity. The oil inlet 607 is located directly at the bottom of the oil chamber and bears a large oil pressure, which would cause the suction component 7 to be oversaturated and drip oil to flow out from the air passage 701, thus causing the electronic cigarette to leak.

[0020] In some embodiments, the main oil chamber 101 is located directly above the secondary oil chamber 601, and the volume of the main oil chamber 101 is 9 mL to 15 mL; the volume of the secondary oil chamber 601 is 1 mL to 2.5 mL. The main oil chamber 101 is located directly above the secondary oil chamber 601, allowing the e-liquid in the main oil chamber 101 to quickly enter the secondary oil chamber 601 through the oil guide channel 604 under the influence of gravity. The volume of the main oil chamber 101 can be 9mL, 10mL, 12mL, 14mL, or 15mL; the volume of the secondary oil chamber 601 can be 1mL, 1.2mL, 1.5mL, 1.8mL, 2mL, or 2.5mL. The volumes of the main oil chamber 101 and the secondary oil chamber 601 listed above allow the oil pressure to be reduced after the e-liquid in the main oil chamber 101 enters the secondary oil chamber 601, so that the oil intake of the oil inlet 607 and the oil intake of the oil suction component 7 are balanced. The optimal effect is achieved when the volume of the main oil chamber 101 is 10mL and the volume of the secondary oil chamber 601 is 1.2mL.

[0021] In some embodiments, the oil-absorbing component 7 is made of polyester fiber, cotton, glass fiber, or ceramic. In this embodiment, the oil-absorbing component 7 is made of polyester fiber, which has a loose structure that absorbs a lot of oil, dense internal fibers that lock in oil effectively, a certain degree of hardness and toughness that prevents it from collapsing after absorbing oil, high temperature resistance so it will not deform when the heating core 8 is heated, and it will not produce harmful substances.

[0024] In some embodiments, the main body 15 further includes an oil sealing element 4 and a bottom shell 5. The oil sealing element 4 is also disposed in the bottom opening of the upper oil tank 1, and the outer wall of the oil sealing element 4 abuts against the inner wall of the upper oil tank 1.
