Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, specifically to an oil-wick separation structure. Background Technology

[0002] Electronic atomizers typically consist of a reservoir for holding e-liquid and a coil for vaporizing it. Most existing products use an integrated coil and reservoir design, meaning the coil is constantly submerged in e-liquid during transport. Due to factors such as changes in ambient temperature, air pressure, or vibration, e-liquid is prone to leakage from the inlet or vent, leading to product contamination, increased costs, and a degraded user experience. Furthermore, the integrated design prevents the coil or reservoir from being separated for replacement, requiring the entire atomizer to be replaced, resulting in resource waste. In addition, long-term submersion can cause e-liquid deterioration in the coil, affecting atomization performance and shortening its lifespan, further increasing operating costs.

[0003] Therefore, developing an oil core separation structure that can effectively solve the oil leakage problem is of great practical significance. Utility Model Content

[0004] To address the problems existing in the prior art, an oil core separation structure is provided. Through a sliding sealing design, the oil circuit is physically isolated during transportation, fundamentally solving the oil leakage problem.

[0005] This utility model provides the following technical solution: This utility model proposes an oil-core separation structure, including an atomizing core assembly and an oil cup assembly; The atomizing core assembly includes a sleeve and an atomizing core disposed inside the sleeve, and at least one atomizing core oil inlet hole is provided on the side wall of the sleeve. The oil cup assembly includes an oil cup and a first sealing element. The oil cup has an oil cavity and an oil hole communicating with the oil cavity. The first sealing element is disposed in the oil hole and has a first oil inlet hole. The atomizing core assembly and the oil cup assembly are detachably connected; the side wall of the sleeve is sealed to the first sealing element, and the sleeve can slide relative to the first sealing element, so that the first oil inlet and the atomizing core oil inlet are mutually misaligned and sealed to isolate each other or mutually aligned and connected through the first sealing element.

[0006] Furthermore, the sliding of the sleeve relative to the first seal is axial sliding.

[0007] Furthermore, when the first oil inlet hole and the atomizing core oil inlet hole are misaligned, the solid part of the first sealant blocks the atomizing core oil inlet hole.

[0008] Furthermore, the sidewall of the sleeve and the first sealing element are sealed together by an interference fit.

[0009] Furthermore, the atomizing core assembly also includes a mouthpiece, a reservoir cotton, a base, and a third seal; the mouthpiece is connected to the top of the sleeve; the base is connected to the bottom of the sleeve; the atomizing core is sealed and installed on the base by the third seal; the reservoir cotton is disposed between the sleeve and the atomizing core and is in contact with the atomizing core.

[0010] Furthermore, it also includes a battery segment assembly, which is sealed to the bottom of the oil cup assembly.

[0011] Furthermore, the oil hole and the first seal are disposed at the bottom of the oil cavity; The battery segment assembly includes a housing and a second seal disposed on the top of the housing; the bottom of the battery segment assembly and the oil cup assembly are sealed to the first seal through the second seal, and the second seal is provided with a second oil inlet hole; The second oil inlet is connected to the first oil inlet, forming a fixed oil passage leading out from the oil cavity; The second seal is sealed to the side wall of the sleeve, and the sleeve can slide relative to the first seal and the second seal, so that the oil inlet of the atomizing core is staggered or aligned with the second oil inlet, thereby achieving isolation or connection between the oil inlet of the atomizing core and the fixed oil circuit.

[0012] Preferably, the oil cup is provided with an axial through hole, and the atomizing core assembly is slidably inserted through the through hole; the first sealing member and the second sealing member are respectively provided with a first sealing hole and a second sealing hole, and the sleeve is inserted through the first sealing hole and the second sealing hole.

[0013] Furthermore, it also includes a limiting component, which is detachably installed on the outside of the sleeve and located between the mouthpiece and the oil cup, to restrict the sliding of the atomizer coil assembly. When the limiting component is removed, the atomizer coil assembly can be pressed down, causing the base to abut against the top of the battery segment assembly, while the atomizer coil oil inlet connects to the fixed oil circuit. The design of the detachable limiting component allows users to easily switch states by simply removing and pressing it before use, greatly improving the product's ease of use and user experience.

[0014] Furthermore, the height of the limiting member is greater than the axial distance between the atomizer core oil inlet and the first oil inlet in the isolated state and less than the sum of the axial distance between the atomizer core oil inlet and the first oil inlet in the isolated state and the diameter of the first oil inlet and the diameter of the atomizer core oil inlet; or, the height of the limiting member is greater than the axial distance between the atomizer core oil inlet and the second oil inlet in the isolated state and less than the sum of the axial distance between the atomizer core oil inlet and the second oil inlet in the isolated state and the diameter of the second oil inlet and the diameter of the atomizer core oil inlet.

[0015] This utility model has the following beneficial technical effects: This invention achieves physical isolation between the atomizing core and e-liquid during transportation through a sliding sealing design, fundamentally cutting off the leakage path and completely solving the problem of e-cigarette cartridge leakage caused by environmental changes during storage and transportation. At the same time, the structure can achieve functional switching by simply adjusting the relative positions of existing components without adding complex parts, and has the advantages of compact structure, low cost and high reliability.

[0040] Example 1 Please see Figure 1 The shown oil-core separation assembly includes an atomizing core assembly 1, an oil cup assembly 2, a battery segment assembly 3, and a limiting component 4.

[0041] like Figure 2-4 As shown, the atomizer core assembly 1 includes a mouthpiece 11, a sleeve 12, an oil reservoir 13, an atomizer core 14, a third seal 15, and a base 16. The third seal 15 is sealed and installed on the base 16, and the bottom of the atomizer core 14 is sealed and connected to the base 16 through the third seal 15. The atomizer core 14 is installed inside the sleeve 12 and sealed and installed on the base 16 through the third seal 15. The oil reservoir 13 is disposed between the sleeve 12 and the atomizer core 14 and is in contact with the atomizer core 14. The mouthpiece 11 is fixedly connected to the top of the sleeve 12. Four atomizer core oil inlet holes 121 are opened on the side wall of the sleeve 12.

[0042] like Figure 5-7 As shown, the oil cup assembly 2 includes an oil cup 21 and a first sealing member 22. An axially oriented through hole 213 is formed through the center of the oil cup 21. The interior of the oil cup 21 has an oil cavity 211 for storing atomized oil, and an oil hole 212 is formed at its bottom. The first sealing member 22 is installed inside the oil hole 212, and its sidewall is press-fitted with the inner wall of the oil hole 212 to form a sealing structure. A first sealing hole 222 is formed through the center of the first sealing member 22, and a vertically oriented first oil inlet hole 221 is formed through its side.

[0043] like Figure 8 As shown, the atomizing core assembly 1 is slidably inserted into the oil cup assembly 2. Specifically, the sleeve 12 is slidably inserted into the through hole 213 of the oil cup 21 and the first sealing hole 222 of the first sealing member 22. The outer wall of the sleeve 12 and the inner wall of the first sealing hole 222 are interference fit, forming a dynamic sealing structure between the atomizing core assembly 1 and the oil cup assembly 2.

[0044] like Figure 9-11 As shown, the battery segment assembly 3 includes a housing 31 and a second sealing member 32 disposed on the top of the housing 31. The second sealing member 32 is disposed on the inner top side of the housing 31, and a second sealing hole 322 is formed through the center of the second sealing member 32, with a second oil inlet hole 321 arranged laterally on its side. In this embodiment, the second oil inlet hole 321 has a top groove structure; in some specific embodiments, the second oil inlet hole 321 may also have a middle groove structure.

[0045] Battery segment assembly 3 is installed at the bottom of oil cup assembly 2 (e.g., Figure 1As shown, specifically, the oil cup 21 is connected to the outer shell 31, and the outer wall of the second seal 32 is press-fitted with the inner bottom wall of the oil cup 21, forming a sealing structure between the battery segment assembly 3 and the oil cup assembly 2. The top of the second seal 32 is tightly fitted with the bottom of the first seal 22, keeping the second oil inlet 321 connected to the first oil inlet 221, forming a fixed oil path led out from the oil chamber 211. The atomizing core assembly 1 passes through the oil cup assembly 2 and is connected to the battery segment assembly. Specifically, the sleeve 12 slides through the second sealing hole 322 of the second seal 32, and the side wall of the sleeve 12 is press-fitted with the inner wall of the second sealing hole 322. The limiting member 4 is detachably sleeved on the outside of the sleeve 12, located between the mouthpiece 11 and the oil cup 21, and is used to limit the sliding of the atomizing core assembly 1.

[0046] Specifically, in this embodiment, the first seal 22, the second seal 32, and the third seal 15 are all made of sealing silicone.

[0047] Specifically, in this embodiment, the height of the limiting member 4 (the distance from the nozzle 11 to the oil cup 21) is 3mm, the diameter of the atomizing core oil inlet hole 121 is 0.8mm, the diameter of the second oil inlet hole 321 is 2mm, and the distance between the atomizing core oil inlet hole 121 and the second oil inlet hole 321 is 2.6mm.

[0048] The operating principle of this embodiment is as follows: During transport, the limiting member 4 is fitted onto the sleeve 12 and positioned between the suction nozzle 11 and the oil cup 21 (e.g., Figure 12 At this point, the height of the limiting member 4 restricts the downward distance of the atomizing core assembly 1, causing the atomizing core oil inlet 121 on the sleeve 12 to be located above the sealing area of ​​the first seal 22. At this time, the atomizing core oil inlet 121 and the second oil inlet 321 are misaligned, and the oil path is cut off. The solid part of the first seal 22 is press-fitted with the side wall of the sleeve 12 located below the atomizing core oil inlet 121, thereby sealing the atomizing core oil inlet 121 and completely isolating the oil chamber 211 from the atomizing core 14, achieving oil-core separation (e.g., ...). Figure 15 Meanwhile, a gap is maintained between the base 16 and the top of the outer casing 31 (in this embodiment, the gap is equal to the height of the limiting member 4) to avoid unnecessary sealing pressure.

[0049] When needed, remove limit piece 4 (e.g.) Figure 13 As shown), press down on the nozzle 11 to move the atomizing core assembly 1 down 3mm (as shown). Figure 14 (As shown). When the nozzle 11 abuts against the top of the oil cup 21, the base 16 abuts against the top of the outer shell 31 of the battery assembly 3, and the atomizer core oil inlet 121 on the sleeve 12 is aligned and connected with the second oil inlet 321 on the second seal 32 (as shown). Figure 16The e-liquid in the oil chamber 211 passes through the first oil inlet 221, the second oil inlet 321 and the atomizing core oil inlet 121 in sequence, permeates into the oil storage cotton 13 and is heated and atomized by the atomizing core 14.

[0050] Example 2 Based on Example 1, the oil core separation structure of this embodiment also includes a suction nozzle cover 5, which is detachably mounted on the suction nozzle 11 (e.g., Figure 17 This prevents contamination of the mouthpiece or airway.

[0051] Example 3 The difference between this embodiment and Embodiment 1 lies only in the first sealing element 22 and the second sealing element 32. Specifically, this embodiment does not use the independent second sealing element 32 as in Embodiment 1, but instead integrates it with the first sealing element 22 in the embodiment into a single structure (i.e., the first sealing element 22 in this embodiment, such as...). Figure 18 (As shown). The first seal 22 integrates an oil inlet function, and its first oil inlet 221 includes a longitudinal opening and a transverse opening that are interconnected.

[0052] During transport, the atomizer core oil inlet 121 is staggered and isolated from the lateral opening.

[0053] When in use, the atomizer coil inlet 121 is aligned and connected to the horizontal opening. E-liquid is supplied to the atomizer coil 14 in sequence through the vertical opening, the horizontal opening, and the atomizer coil inlet 121.

[0054] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
