Description

Technical Field

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

[0002] E-cigarettes are electronic devices that generate an aerosol by heating e-liquid for users to inhale. The design of the coil structure plays a crucial role in the performance and user experience of e-cigarettes. In traditional e-cigarette designs, the atomizer coil is directly immersed in the e-liquid. This structure ensures good contact between the e-liquid and the coil during normal use, resulting in stable atomization. However, this design reveals significant shortcomings during the storage and transportation of e-cigarettes. For example, vibrations from vehicle movement, shaking during handling, and negative pressure caused by changes in air pressure at different altitudes can disrupt the stability of the e-liquid, causing leakage from weak points in the cartridge's seal. This leakage not only affects the product's appearance but may also contaminate surrounding items, reducing the consumer's experience.

[0003] To address this issue, some existing technologies have proposed a coil-electrode separation design, storing e-liquid in an independent compartment to keep it separate from the atomizer coil during storage, thus preventing leakage to some extent. However, existing coil-electrode separation technologies still have room for improvement. For example, some designs achieve coil-electrode separation through complex mechanical or electronic structures, which increases the difficulty of the manufacturing process, leading to higher production costs and hindering large-scale production and market promotion. Furthermore, complex designs may increase the probability of product malfunctions during use. Other designs, while achieving coil-electrode separation, lack precise control over e-liquid discharge, potentially leading to unstable e-liquid supply and consequently affecting atomization performance and user experience. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides an oil-wick separation device. Through the isolation structure design and adjustable sealing component design inside the oil cup, the e-liquid and the inner wick can be effectively separated, ensuring the performance while preventing oil leakage during storage and transportation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An oil-wick separation device includes an oil cup with a suction port at one end and an installation port at the other end; a sealing isolator placed inside the oil cup and dividing it into an oil storage chamber and a transition chamber; an oil-passing assembly filled in the transition chamber; an atomizing core assembly disposed within the oil-passing assembly; and a base assembly disposed at one end of the installation port of the oil cup, sealed, and electrically connected to the atomizing core assembly. The oil storage chamber is located near the suction port, and the suction port is connected to the atomizing core assembly through a suction channel. The sealing isolator has an oil outlet that allows e-liquid to flow from the oil storage chamber into the transition chamber. An adjustable sealing element is disposed inside the oil outlet, and an adjustment handle disposed on the sealing element protrudes outside the base assembly through adjustment channels pre-drilled on the oil-passing assembly and the base assembly.

[0007] Specifically, the oil-passing assembly includes an integral cotton filling the transition cavity and an oil-passing sleeve disposed between the integral cotton and the inner wall of the transition cavity. The integral cotton has an atomization placement hole and a first adjustment perforation. The atomization placement hole is used to place the atomization core assembly and communicate with the suction channel. The first adjustment perforation matches the adjustment handle.

[0008] Specifically, the atomizing core assembly includes an atomizing sleeve disposed within the oil-passing assembly and connected to the suction channel, multiple oil-passing holes penetrating the side wall of the atomizing sleeve, an oil-guiding cotton disposed within the atomizing sleeve to cover the oil-passing holes, and an atomizing heating wire disposed within the oil-guiding cotton and electrically connected to the base assembly. The oil-guiding cotton is provided with a smoke channel coaxial with the atomizing sleeve.

[0009] Specifically, the base assembly includes a bottom cover that is fastened to the mounting port of the oil cup, a bottom seal disposed between the bottom cover and the transition cavity, oil-absorbing cotton filled between the bottom seal and the bottom cover, and an exposed electrode disposed on the bottom cover and electrically connected to the atomizing core assembly. The bottom cover and the bottom seal are provided with an air passage and a second adjustment perforation. The air passage is used to introduce external air into the atomizing core assembly, and the second adjustment perforation matches the adjustment handle. The first and second adjustment perforations together constitute the adjustment channel.

[0010] Specifically, an isolation ring is provided at the inner end of the airway to prevent the atomizing heating wire from directly contacting the bottom seal.

[0011] Specifically, the oil outlet includes at least a narrowed section, the inner diameter of which is smaller than that of the sealing member, so that when the sealing member is at least partially inserted into the narrowed section, it blocks the oil outlet and interrupts the flow of e-liquid.

[0012] Specifically, the inner wall of the reduced diameter section is provided with a plurality of sealing protrusions arranged at intervals along the axial direction.

[0013] Specifically, the oil outlet also includes a flared section adjacent to the narrowed section, the inner diameter of which is larger than that of the sealing member, so that when the sealing member is inside the flared section, a space is formed for the e-liquid to pass through.

[0014] Specifically, the inner wall of the flared portion is provided with positioning protrusions arranged at intervals along the circumference.

[0015] Specifically, the outer diameter of the adjusting handle is smaller than the inner diameter of the narrowed section, so that when the adjusting handle is inside the narrowed section, a space is formed for the e-liquid to pass through.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) This utility model achieves the isolation between the e-liquid storage and the atomizing core through the sealing isolation component structure inside the oil cup. Combined with the oil outlet and adjustable sealing component structure configured on the sealing isolation component, it achieves effective control over the timing of e-liquid outflow, avoiding e-liquid leakage during storage and transportation, while ensuring the effect during normal use. This utility model has a simple structure, ingenious design, and is easy to use, making it suitable for application in electronic cigarettes.

[0018] (2) This utility model has made a specific design on the matching structure of the oil outlet and the sealing part. The structure of the reduced diameter part and the sealing convex ring has increased the sealing effect of the sealing part on the oil outlet. The structure of the flared part and the positioning convex block ensures that the e-liquid flows out smoothly during normal use. At the same time, the matching design of the adjustment handle also ensures that it does not affect normal use.

[0019] (3) The present invention adopts a structure design in which the base position exposes the adjustment handle, which ensures that the addition of the sealing component does not affect the overall packaging structure of the e-liquid cartridge, nor does it affect the packaging and normal use of the e-liquid cartridge. At the same time, it avoids the possibility of e-liquid leakage along the adjustment handle. The base position is at the far end of the oil storage cavity. After the e-liquid flows out, it is mainly absorbed by the integrated cotton. A small amount of remaining e-liquid can be blocked by the base component. Combined with the sealing protrusion ring with a similar structure that can be configured in the second adjustment hole, it can fully avoid leakage. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0034] Example

[0035] like Figures 1 to 8As shown, the oil-wick separation device includes an oil cup 1 with a suction port 2 at one end and an installation port 3 at the other end; a sealing isolator 4 placed inside the oil cup and dividing it into an oil storage chamber 5 and a transition chamber 6; an oil-passing assembly 20 filled in the transition chamber 6; an atomizing core assembly 30 disposed within the oil-passing assembly 20; and a base assembly 40 disposed at one end of the installation port 3 of the oil cup 1 and electrically connected to the atomizing core assembly 30. The oil storage chamber 5 is located near the suction port 2, and the suction port 2 is connected to the atomizing core assembly 30 via a suction channel 7. The sealing isolator 4 has an oil outlet 10 that allows e-liquid to flow from the oil storage chamber 5 into the transition chamber 6. An adjustable sealing member 8 is disposed within the oil outlet 10, and an adjustment handle 9 disposed on the sealing member 8 protrudes outside the base assembly 40 through adjustment holes pre-drilled on the oil-passing assembly 20 and the base assembly 40. The suction port is also equipped with a mouthpiece plug 15.

[0036] The oil outlet 10 is generally shaped like a through hole, specifically including a narrowed section 11 and an flared section 12 adjacent to the narrowed section 11. The inner diameter of the narrowed section is smaller than that of the sealing member, so that when the sealing member is at least partially inserted into the narrowed section, it blocks the oil outlet and interrupts the flow of e-liquid. The inner diameter of the flared section is larger than that of the sealing member, so that when the sealing member is inside the flared section, it creates space for e-liquid to pass through. Preferably, the flared section is close to the oil storage chamber, thus forming a structure with the narrowed section at the bottom and the flared section at the top. When the sealing member is in the position of the narrowed section, it closes the e-liquid outlet for easy storage and transportation. The adjustment handle has a relatively long section exposed outside the base assembly. When needed, the adjustment handle is pressed from the outside to the inside to move the sealing member away from the narrowed section and into the flared section, thereby opening the channel of the e-liquid outlet and allowing the e-liquid to flow smoothly into the oil passing assembly and into the atomizing core assembly. The sealing isolation element 4 can be made of 60-degree silicone material, which has a certain elasticity. The reduced diameter part configured in the oil outlet on it can form a relatively tight contact with the sealing element made of PCTG material to achieve the sealing effect. The sealing element is usually configured in a cylindrical shape.

[0037] In a further design, the inner wall of the reduced diameter section 11 is provided with a plurality of sealing protrusions 13 arranged at intervals along the axial direction, thereby making better contact with the sealing component to form a sealing structure with better effect, and maintaining a good sealing effect when the sealing component is in multiple positions within the reduced diameter section.

[0038] In a further design, the inner wall of the flared portion 12 is provided with positioning protrusions 14 arranged at intervals along the circumference. The inner side of the positioning protrusions contacts the side wall of the sealing component located at that position to form a straightening effect, ensuring that the sealing component and its adjustment handle can form a stable oil outlet space relative to the oil outlet, facilitating the flow of e-liquid during use. Moreover, the structural design of the positioning protrusions 14, through the notches formed by their interval arrangement in the flared portion, can also easily realize the preset control of the e-liquid discharge volume in the open state, ensuring a stable and appropriate amount of e-liquid output.

[0039] Specifically, the outer diameter of the adjustment handle 9 is smaller than the inner diameter of the narrowed section, creating space for e-liquid to pass through when the adjustment handle is within the narrowed section. The adjustment handle and the sealing component are designed as a single piece of the same material, facilitating practical use and manufacturing. The adjustment handle can have a gradually narrowing diameter design from the sealing component end to the exposed end, such as a stepped or gradient diameter reduction structure. This allows for a smaller adjustment channel at the exposed end that mates with the base assembly, reducing the possibility of e-liquid leakage from the adjustment handle. Furthermore, a sealing structure similar to the sealing ring 13 can be installed within the adjustment channel in the base assembly to further improve the sealing between the base assembly and the adjustment handle, preventing e-liquid leakage.

[0040] Specifically, the e-liquid passing assembly 20 includes an integral cotton 21 filled within the transition cavity 6, and an e-liquid passing sleeve 22 disposed between the integral cotton 21 and the inner wall of the transition cavity 6. The integral cotton has an atomization placement hole 23 and a first adjustment perforation 24. The atomization placement hole 23 is used to place the atomization core assembly 30 and communicates with the suction channel 7. The first adjustment perforation 24 matches the adjustment handle 9. The size of the first adjustment perforation is not specifically limited, as long as it ensures smooth movement of the adjustment handle without excessive contact with e-liquid. The integral cotton is made of high-polymer cotton material, which can effectively store the e-liquid that flows out. The e-liquid passing sleeve can be made of PCTG material, which can be connected to the sealing silicone components at the top and bottom to ensure that the e-liquid stored in the integral cotton does not leak out.

[0041] Specifically, the atomizing core assembly 30 includes an atomizing sleeve 31 housed within the oil-passing assembly 20 and communicating with the suction channel 7; multiple oil-passing holes 32 penetrating the side wall of the atomizing sleeve 31; an oil-guiding cotton 33 housed within the atomizing sleeve 31 to cover the oil-passing holes 32; and an atomizing heating wire 34 housed within the oil-guiding cotton 33 and electrically connected to the base assembly 40. The oil-guiding cotton 33 has a smoke channel 35 coaxial with the atomizing sleeve 31. The e-liquid stored in the integrated cotton further penetrates into the oil-guiding cotton through the oil-passing holes, forming an aerosol under the action of the atomizing heating wire, and then exits from the suction port 2 through the suction channel for the user to inhale.

[0042] Specifically, the base assembly 40 includes a bottom cover 41 that is fastened to the mounting port 3 of the oil cup 1, a bottom seal 42 disposed between the bottom cover 41 and the transition cavity 6, oil-absorbing cotton 43 filled between the bottom seal 42 and the bottom cover 41, and an exposed electrode 44 disposed on the bottom cover 41 and electrically connected to the atomizing heating wire 34 of the atomizing core assembly 30. The bottom cover and the bottom seal are provided with an air passage 45 and a second adjustment perforation 46. The air passage 45 is used to introduce external air into the atomizing core assembly 30; that is, a through hole corresponding to the atomizing sleeve is provided on the bottom seal, and an air hole communicating with the outside is opened on the bottom cover. The air hole and the through hole are connected by an internal channel to introduce external air. The second adjustment perforation 46 matches the adjustment handle 9. The second adjustment perforation and the first adjustment perforation together constitute an adjustment channel. The second adjustment perforation is configured corresponding to the small end of the adjustment handle. A sealing protrusion ring structure can be added inside the hole to ensure the sealing of the adjustment handle position and prevent e-liquid leakage. The bottom seal can be made of the same 60-degree silicone material as the sealing isolation component 4, ensuring the opening setting and corresponding sealing effect. The oil-absorbing cotton is made of high-polymer cotton material, which has a high efficiency in retaining e-liquid and can effectively prevent e-liquid from leaking from the base.

[0043] Specifically, an isolation ring 47 is provided at the inner end of the air passage 45 to prevent the atomizing heating wire 34 from directly contacting the bottom seal 42.

[0044] In the finished packaging state, the sealing component is positioned at the narrowed section of the oil outlet, and the adjusting handle is exposed at the bottom of the base. At this point, due to the sealing effect of the sealing component, e-liquid will not flow out of the oil reservoir, ensuring no leakage. Simultaneously, due to sufficient compressive frictional resistance between the sealing component and the narrowed section, and between the adjusting handle and the base assembly, coupled with a certain amount of extra space in the packaging, the sealing component and adjusting handle will not be easily moved, further preventing the possibility of e-liquid leakage during storage and transportation. When the user receives the product and opens the packaging to prepare for use, first apply force to the adjusting handle from the bottom, pressing it inwards to allow the sealing component to move from the narrowed section into the widened section, thereby opening the oil outlet channel, allowing e-liquid to flow out. Afterwards, assemble and use as normal to begin vaping.

[0045] During the operation of pressing the adjustment handle, you can press it all the way down in one go to achieve the preset maximum amount of e-liquid discharged, or you can press it gradually to achieve the desired amount of e-liquid discharged. In addition, when the stored e-liquid is not used up and needs to be stored for a longer period of time, the sealing piece can be pulled outward and back into the constricted section through the exposed adjustment handle to reseal the outlet, preventing extra e-liquid from flowing out of the reservoir and allowing for longer storage without affecting the taste.

[0046] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any changes made based on the design principles of this utility model, or any non-creative changes made on this basis, shall fall within the scope of protection of this utility model.
