AI Technical Summary
In existing electronic cigarettes, the speed at which e-liquid enters the integrated cotton is limited, resulting in low inhalation and transmission efficiency. At the same time, the absence of an integrated cotton can easily lead to oil leakage.
An oil storage cavity is set between the outer shell and the integrated cotton. Through the cooperation of the oil-guiding cotton and the heating wire assembly, the e-liquid is continuously supplied and heated for evaporation, increasing the contact area between the e-liquid and the integrated cotton, and achieving stable transmission through capillary action.
It improves the efficiency of e-liquid intake and transmission, avoids leakage, ensures stable flavor, and prevents the coil from burning.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electronic cigarette-related devices, and in particular to an electronic cigarette oil guiding structure with gradient capillary channels. Background Technology
[0002] Electronic cigarettes, also known as virtual cigarettes, vaporizers, or aerosol generators, are primarily used for smoking cessation or as a substitute for cigarettes.
[0003] Existing e-cigarette e-liquids often employ two methods: composite atomizing core components and independent atomizing cores.
[0004] In this process, the composite atomizing core assembly delivers e-liquid into the integrated cotton through small holes on the side of the outer tube of the atomizing core, which in turn enters the atomizing core. This results in a very limited speed at which e-liquid enters the integrated cotton; moreover, the e-liquid can only come into contact with the side of the integrated cotton, and the fibers of the integrated cotton are distributed longitudinally. The side is prone to forming an oil film and does not easily generate capillary action, thereby reducing the efficiency of e-liquid inhalation and transmission, and causing the phenomenon of dry vaping and burnt core.
[0005] Independent atomizer coils come into direct contact with e-liquid, and since they lack an integrated cotton layer for buffering and storing e-liquid, they are highly susceptible to leakage of e-liquid through the inner holes of the atomizer coil. Utility Model Content
[0006] The purpose of this invention is to provide an e-cigarette oil guiding structure with gradient capillary channels to alleviate the technical problem in the prior art where the speed at which e-liquid enters the integrated cotton limits the efficiency of inhalation and transmission, and also to avoid oil leakage caused by not having an integrated cotton.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] In a first aspect, this utility model provides an electronic cigarette oil guiding structure with gradient capillary channels, including an outer shell, an integrated cotton, an oil guiding cotton and a heating wire assembly. The integrated cotton is provided inside the outer shell, and an oil storage cavity is opened inside the outer shell for supplying oil to the integrated cotton.
[0009] The oil-wicking cotton is disposed inside the outer shell, and the oil-wicking cotton is used to absorb the e-liquid inside the integrated cotton.
[0010] The heating wire assembly is disposed inside the oil-guiding cotton, and the heating wire assembly is used to heat the oil-guiding cotton so that the e-liquid inside the oil-guiding cotton evaporates.
[0011] Furthermore, the outer casing has multiple oil inlet holes, and each of the oil inlet holes is connected to the oil storage cavity.
[0012] Furthermore, the inner wall of the outer shell is provided with a support block, which supports the integral cotton.
[0013] Furthermore, the e-cigarette oil guiding structure with gradient capillary channels also includes an atomizing core, which is disposed within the outer shell and the oil guiding cotton is disposed inside the atomizing core;
[0014] The atomizing core has a long through hole, which is used to connect the integrated cotton and the oil-guiding cotton.
[0015] Furthermore, the e-cigarette oil guiding structure with gradient capillary channels also includes a glass fiber tube, which is disposed inside the integrated cotton and connected to the atomizing core.
[0016] Furthermore, a U-shaped groove is provided at the end where the atomizing core is connected to the fiberglass tube.
[0017] Furthermore, the oil-wicking cotton includes multiple tubular cotton, and the multiple tubular cotton are sequentially nested and connected;
[0018] The heating wire assembly is located inside the innermost tubular cotton.
[0019] Furthermore, the heating wire assembly includes a heating mesh and heating wire leads, wherein the heating mesh is disposed within the oil-guiding cotton;
[0020] One end of the heating wire pin is connected to the heating mesh, and the other end is used to connect to an external power supply device.
[0021] Furthermore, the e-cigarette oil guiding structure with gradient capillary channels also includes a sealing element, which is connected to the end of the outer shell away from the integrated cotton, and the sealing element is connected to the atomizing core.
[0022] Furthermore, the e-cigarette oil guiding structure with gradient capillary channels also includes a top block, which is disposed within the sealing member;
[0023] The end of the heating wire assembly furthest from the oil-wicking cotton protrudes from the top block.
[0024] This utility model can achieve the following beneficial effects:
[0025] In a first aspect, this utility model provides an electronic cigarette wicking structure with gradient capillary channels, including an outer shell, an integrated cotton, an oil-wicking cotton, and a heating wire assembly. The integrated cotton is disposed inside the outer shell, and an oil storage cavity is formed inside the outer shell for supplying oil to the integrated cotton. The oil-wicking cotton is disposed inside the outer shell and is used to absorb the e-liquid in the integrated cotton. The heating wire assembly is disposed inside the oil-wicking cotton and is used to heat the oil-wicking cotton to cause the e-liquid in the oil-wicking cotton to evaporate.
[0026] In this invention, the outer shell is a tubular structure, specifically an elliptical tube, a square tube, or an irregular tubular structure, etc., with an integral cotton piece also tubular inside. The first end of the integral cotton piece is flush with one end of the outer shell, while its second end is located inside the outer shell. An oil storage chamber is provided between the outer shell and the second end of the integral cotton piece, and this oil storage chamber contains e-liquid. Through the storage function of the oil storage chamber, the e-liquid is continuously supplied to the integral cotton piece. After the integral cotton piece absorbs a certain amount of e-liquid, it comes into contact with the oil-guiding cotton. When the oil-guiding cotton is heated by the heating wire assembly, the e-liquid evaporates, and its capillary pores become unsaturated. A pressure difference is generated between the e-liquid in the oil-guiding cotton and the e-liquid in the integral cotton. Under the pressure difference and capillary action, the e-liquid in the integral cotton piece flows to the oil-guiding cotton until it reaches a saturated state again. Then, after being heated by the heating wire assembly, the e-liquid on the oil-guiding cotton is heated and vaporized, and is drawn towards the mouthpiece.
[0027] Compared with existing technologies, the e-cigarette wicking structure with gradient capillary channels provided by this utility model greatly increases the contact area between e-liquid and the integrated cotton by setting an oil storage cavity between the outer shell and the integrated cotton. It also allows for end-face contact between the e-liquid and the cotton fibers, which facilitates capillary transport of the e-liquid and avoids the formation of an oil film that can occur with side contact. This results in stable and efficient transport of e-liquid between the external oil tank, the integrated cotton, and the wicking cotton, achieving rapid coil lubrication and ensuring a stable flavor while preventing the coil from burning or becoming scorched.
[0028] In summary, this utility model at least alleviates the technical problem of low inhalation and transmission efficiency caused by the speed limitation of e-liquid entering the integrated cotton in the prior art, and also avoids the situation of oil leakage caused by not setting the integrated cotton.
