Description

Technical Field

[0001] This utility model relates to the field of electronic atomization, and in particular to a novel electronic atomization core structure. Background Technology As the core component of electronic atomizing devices, the electronic atomizing coil works by using electrical energy to drive a heating element (such as a resistance wire or mesh coil) to heat the oil-conducting medium (such as organic cotton or porous ceramic), causing the adsorbed functional liquid to atomize and form an inhalable aerosol. This technology, due to its efficient and controllable atomization method, is widely used in areas such as quitting smoking, medical fumigation (e.g., respiratory drug delivery), and cosmetic atomization (e.g., serum atomization for skincare), offering advantages such as precise dosage control, low residue, and a superior user experience.

[0002] Currently, the mainstream electronic atomizer coil support types include single-layer straight tube support structures and dual-support structures consisting of an inner straight tube support, a reservoir, and an outer straight tube support. These supports on the market are mostly made of metal, which has good dimensional accuracy and mechanical strength and can meet the current product design requirements. However, the use of existing metal supports still poses a significant safety hazard to the atomizer coil.

[0003] Firstly, in both the single-layer metal straight tube support structure and the dual-support structure consisting of an inner metal straight tube support, oil storage cotton, and an outer metal straight tube support, the atomizing chamber formed by the heating element is tightly fitted with oil-guiding cotton. The high-temperature aerogel from the atomization diffuses outward through the oil-guiding cotton and comes into contact with the single-layer metal straight tube support or the inner metal straight tube support that is against the outside of the oil-guiding cotton. At this time, the high-temperature aerogel will cause these two metal supports to heat up rapidly, and through the thermal conductivity of the metal, the oil storage cotton tightly fitted to the outside of the metal support will soften or even melt. Ultimately, this will cause the atomizing liquid conduction and pressure relief of the oil storage cotton to fail, and the interruption of oil guiding will trigger a vicious cycle of increased temperature of the heating element, further aggravating the oxidation reaction of the metal support at high temperature. In the end, the amount of metal ions such as iron ions, nickel ions, and chromium ions released will increase, which will greatly endanger the health and safety of the atomizer coil user.

[0004] Finally, in addition to the precipitation of metal ions and changes in the structure of the oil storage cotton, the metal support tube is also a good conductor. In the process of fixing the electrode pins of the heating mesh, the electrode pins must be coated with rubber to avoid direct contact between the electrode pins and the support tube, which would cause a short circuit. On the one hand, if the rubber-coated pins are fixed too tightly with the clips, they may scratch the rubber coating and cause a short circuit. On the other hand, if they are too loose, they may cause the heating mesh to deform. This brings extremely high technical difficulty and waste of defective products to the assembly of the atomizing core.

[0005] Therefore, it is necessary to provide a new type of electronic atomizing core structure that can reduce the harm of metal ions to the human body during heating and effectively prevent the oil reservoir cotton from softening. Utility Model Content

[0006] The purpose of this invention is to provide a novel electronic atomizing core structure that can reduce the harm of metal ions to the human body during heating and effectively prevent the oil storage cotton from softening.

[0007] According to one aspect of this application, a novel electronic atomizing core structure is provided, which internally stores an atomizing liquid, the structure comprising: Oil-wicking cotton, carrying atomizing fluid; A heating element is located inside the oil-guiding cotton. The heating element heats the atomizing liquid carried by the oil-guiding cotton, and the atomizing liquid atomizes to form a high-temperature aerosol. An inner support tube extends along a first direction, and when viewed along the first direction, the inner support tube is located outside the heating element; The oil-absorbing cotton, viewed along the first direction, abuts against the inner support tube and is located on the outside of the inner support tube; The inner support is made of high-temperature resistant plastic. High-temperature aerosol is generated on the surface of the heating element and flows in the first direction. It flows through the inner support tube area and quickly heats the inner support tube. The heat from the aerosol flows sequentially to the inner support tube and the oil storage cotton. The inner support tube isolates part of the heat from the high-temperature aerosol from entering the oil storage cotton.

[0008] More preferably, the high-temperature resistant plastic material of the inner support tube is any one of PEEK, PEKK, PPSU, PPA, PA66, and PPS.

[0009] More preferably, the structure further includes: An outer support tube extends along the first direction, and when viewed along the first direction, it abuts against the oil-storing cotton and is located on the side of the oil-storing cotton away from the inner support tube. The outer support tube array is provided with several integrally formed oil-permeable holes that penetrate the outer support tube.

[0010] More preferably, the material of the outer support tube is metal or plastic, and the plastic material is more specifically any one of PP, PA66, PC, PPS, PEEK, PEKK, PPSU, and PPA; Among them, the plastic material can withstand temperatures exceeding 120℃.

[0011] More preferably, the oil-guiding cotton also extends along the first direction. When viewed along the first direction, the oil-guiding cotton is fixedly connected to the inside of the inner support tube and is located between the heating element and the inner support tube. The heating element is in contact with the inner side of the oil-wicking cotton.

[0012] More preferably, the inner support tube is provided with a plurality of internal oil permeable holes, and at least one notch is opened at the top along the first direction as an air exchange groove.

[0013] More preferably, the heating element further includes: The heating mesh surface is in close contact with the inner side of the oil-wicking cotton; The pin is fixedly connected to the side of the heating mesh surface away from the oil-guiding cotton, and is electrically connected to the heating mesh surface; The pin extends in a direction opposite to the first direction.

[0014] More preferably, the inner support tube and the outer support tube are formed by any one or a combination of tube extrusion, injection molding, high temperature molding, powder sintering, laser cutting and lathe machining.

[0015] This utility model has the following beneficial effects: The inner support tube is made of high-temperature resistant plastic, and the heat from the high-temperature aerosol passes through the inner support tube before entering the oil-collecting cotton. This prevents the inner support tube from undergoing a metal oxidation reaction with the high-temperature aerosol, thus reducing the release of metal ions and minimizing the harm to the human body from metal ions generated during the heating of the electronic atomizing core structure. Furthermore, the design of using a high-temperature resistant plastic inner support tube to isolate some of the heat from the high-temperature aerosol from entering the oil-collecting cotton effectively prevents the oil-collecting cotton from softening at high temperatures, preventing conduction and pressure relief failure of the atomizing liquid.

[0021] Please refer to Figure 1 - Figure 3 One embodiment of this application provides a novel electronic atomizing core structure 100, which stores atomizing liquid inside. The structure 100 includes: oil-guiding cotton 50, heating element 10, inner support tube 20 and oil-storing cotton 30.

[0022] The oil-guiding cotton 50 carries atomizing liquid. The heating element 10 is located inside the oil-guiding cotton 50, and heats the atomizing liquid carried by the oil-guiding cotton 50, causing the atomizing liquid to atomize and form a high-temperature aerosol. The inner support tube 20 extends along the first direction F1, and when viewed along the first direction F1, the inner support tube 20 is located outside the heating element 10. The oil-storing cotton 30, when viewed along the first direction F1, abuts against the inner support tube 20 and is located outside the inner support tube 20. The inner support is made of high-temperature resistant plastic. The high-temperature aerosol in the structure 100 is generated on the surface of the heating element 10 and flows along the first direction F1. It flows through the area of ​​the inner support tube 20 and rapidly heats the inner support tube 20. The heat of the aerosol flows sequentially to the inner support tube 20 and the oil-storing cotton 30, and the inner support tube 20 isolates part of the heat of the high-temperature aerosol from entering the oil-storing cotton 30.

[0023] In traditional e-cigarette cores, the reservoir cotton 30 has limited temperature resistance, typically softening or even melting at sustained temperatures of 180 degrees Celsius. Furthermore, the high-temperature aerogel generated by the heating element 10 in most e-cigarette cores can reach temperatures exceeding 200 degrees Celsius. Therefore, with prolonged use, the reservoir cotton 30 usually deforms or melts, significantly reducing the conductivity and pressure relief efficiency of the atomized liquid within it. In this application, the inner support tube 20 is made of high-temperature resistant plastic. High-temperature resistant plastics generally have poor thermal conductivity and good support properties. When the high-temperature aerosol generated internally moves towards the reservoir cotton 30, it insulates some of the heat, ensuring that the contact temperature of the reservoir cotton 30 remains below the deformation and melting temperatures, thus improving the user experience and extending the lifespan of the e-cigarette core. In addition, the non-metallic inner support tube 20 prevents oxidation reactions on its surface after contact with high-temperature aerosols, thus reducing the risk of iron, chromium, nickel, and other metal ions being inhaled from the atomized gas.

[0024] More preferably, the high-temperature resistant plastic material of the inner support tube 20 is any one of PEEK, PEKK, PPSU, PPA, PA66, and PPS.

[0025] The inner support tube 20 is made of specific high-temperature resistant plastics such as PEEK, PEKK, PPSU, PPA, PA66, or PPS, achieving excellent overall technical performance. These engineering plastics generally have significantly higher heat resistance than conventional plastics (long-term operating temperatures far exceed the atomizer core's operating temperature), ensuring that the inner support tube 20 maintains 100% structural integrity and dimensional stability under continuous impact from high-temperature aerosols, fundamentally eliminating the risk of ion release associated with metal materials. PEEK and PEKK, as high-performance specialty plastics, have the highest heat resistance (up to 250℃ or higher), excellent mechanical strength, creep resistance, and fatigue resistance, providing the inner support tube 20 with top-tier long-term durability and reliability, especially suitable for applications requiring ultra-high temperatures, high power, or long lifespan. PPSU, on the other hand, excels in toughness, impact resistance, and hydrolytic stability, resisting cracking under repeated thermal shocks and exhibiting good chemical corrosion resistance, making it adaptable to complex atomizer environments. PPA and PA66 (Nylon 66) offer excellent heat resistance and mechanical strength while maintaining high cost-effectiveness and superior processing fluidity. This facilitates the molding of complex, dimensionally precise support tubes using processes like injection molding, enabling large-scale production and cost control. PPS, on the other hand, stands out for its extremely high rigidity, superior chemical resistance, and inherent flame-retardant properties. Its excellent dimensional stability ensures precise shape even in high-temperature and humid environments, effectively guaranteeing assembly accuracy with the heating element 10, oil-wicking cotton 50, and outer support. These material choices provide flexible and high-performance solutions for product design, allowing for optimized matching based on different cost controls, temperature resistance levels, strength requirements, and processing characteristics. This ensures safety while comprehensively improving the overall performance and production economy of the atomizing core.

[0026] More preferably, the structure 100 further includes an external support tube 40.

[0027] The outer support tube 40 extends along the first direction F1, and when viewed along the first direction F1, it abuts against the oil storage cotton 30 and is located on the side of the oil storage cotton 30 opposite to the inner support tube 20. The tube surface of the outer support tube 40 is provided with a plurality of integrally formed external oil penetration holes 41 that penetrate the outer support tube 40.

[0028] In this application, the electronic atomizing core structure 100 also includes an outer support tube 40. The outer support tube 40, together with the oil-collecting cotton 30 and the inner support tube 20, forms a double-support structure 100. Compared to a single support, the double support structure 100 can fix the oil-collecting cotton 30 through bidirectional structure 100, reducing the amount of deformation caused by compression of the oil-collecting cotton 30. The array of external oil-permeable holes 41 on the outer support tube 40 can achieve uniform oil guidance of the oil-collecting cotton 30, thereby improving atomization efficiency and preventing local dry burning of the oil-collecting cotton 30. In addition to the double support tube design adopted in this application, the single support tube design with only the inner support tube 20 can also reduce the amount of metal ion precipitation during heating of the atomizing core by using high-temperature resistant plastic as the support tube material, and can effectively prevent the oil-collecting cotton 30 from softening.

[0029] More preferably, the outer support tube 40 is made of metal or plastic, and the plastic material is more specifically any one of PP, PA66, PC, PPS, PEEK, PEKK, PPSU, and PPA. The plastic material is heat resistant to over 120°C.

[0030] The outer support tube 40 can be made of metal or specific engineering plastics, such as PP, PA66, PC, PPS, PEEK, PEKK, PPSU, and PPA, to protect the internal structure 100, maintain its shape stability, and ensure smooth oil seepage. If a metal material, such as stainless steel, is chosen, its main advantage lies in its extremely high mechanical strength and rigidity, providing the strongest physical protection for the entire atomizing core and preventing deformation of the internal structure 100, such as the oil reservoir cotton 30, caused by external pressure. However, its high thermal conductivity may be a weakness, potentially allowing heat from the external environment to enter or causing internal residual heat to dissipate more quickly, and in extreme cases, there is still a slight risk of metal ion migration. Using plastic materials with a temperature resistance exceeding 120℃ offers a series of significant technical advantages, with different materials having different strengths. PP (polypropylene) is known for its excellent cost-effectiveness and superior chemical inertness, resisting corrosion from various atomizing liquids and suitable for disposable or low-cost products. PA66 (Nylon 66) strikes a good balance between temperature resistance, strength, and toughness, and its excellent abrasion resistance allows it to withstand more severe physical friction. PC (Polycarbonate) has extremely high impact strength and transparency, facilitating visual inspection of internal atomized liquid levels during production or by users; however, its resistance to certain chemical solvents needs to be assessed beforehand. PPS offers extremely high rigidity, excellent chemical resistance, and superior dimensional stability, ensuring the support structure remains intact in high-temperature and humid environments. High-performance plastics such as PEEK, PEKK, PPSU, and PPA have the most outstanding heat resistance (far exceeding 120°C) and overall mechanical properties. PEEK and PEKK, in particular, ensure that the external support tube 40 does not experience any thermal deformation or performance degradation throughout its entire product lifecycle in reusable or high-power devices where ultimate safety, durability, and high-temperature stability are paramount.

[0031] More preferably, the oil-wicking cotton 50 also extends along the first direction F1. When viewed along the first direction F1, the oil-wicking cotton 50 is fixedly connected to the inside of the inner support tube 20 and is located between the heating element 10 and the inner support tube 20. The heating element 10 abuts against the inner side of the oil-wicking cotton 50.

[0032] The oil-wicking cotton 50 tightly wraps around the heating element 10, ensuring complete coverage of the heating surface with atomized liquid and eliminating localized hot spots from dry burning. The fiber structure 100 of the oil-wicking cotton 50 absorbs some of the heat generated by the heating element 10, reducing the heat transferred to the inner support tube 20. Furthermore, the oil-wicking cotton 50 prevents the heating element 10 from directly contacting the inner support tube 20, further reducing the risk of dry burning of the atomizer core's internal structure 100 by high-temperature aerosols.

[0033] More preferably, the inner support tube 20 is provided with a plurality of inner oil penetration holes 21, and at least one notch is opened at the top along the first direction F1 as an air exchange groove 22.

[0034] The inner oil-permeable hole 21 allows the atomized liquid in the oil-storage cotton 30 to radially permeate into the oil-guiding cotton 50, ensuring a continuous supply of atomized liquid to the heating element 10. The size and distribution of the holes directly affect the oil guiding rate of the atomized liquid. The inner oil-permeable hole 21 and the outer oil-permeable hole 41 form a gradient oil guiding structure 100 with the inner oil-permeable hole 21 being larger and the outer oil-permeable hole 41 being smaller, establishing a negative pressure balance and preventing oil leakage or dry burning to a certain extent. The atomized liquid first enters the oil-storage cotton 30 through the outer oil-permeable hole 41, then reaches the oil-guiding cotton 50 through the inner oil-permeable hole 21, and is finally atomized by the heating element 10. The ventilation groove 22 extends along the first direction F1, providing a direction for aerosol flow, optimizing the atomization flow of the aerosol, and avoiding the accumulation of condensate when not heated. The ventilation groove 22, together with the inner oil-permeable hole 21 and the outer oil-permeable hole 41, constitutes an oil-gas separation system. The aerosol is axially discharged through the ventilation groove 22, avoiding mixing with the un-atomized atomized liquid.

[0035] More preferably, the heating element 10 further includes a heating mesh surface 11 and pin terminals 12.

[0036] The heating mesh surface 11 is in close contact with the inner side of the oil-guiding cotton 50. The lead end 12 is fixedly connected to the side of the heating mesh surface 11 away from the oil-guiding cotton 50 and is electrically connected to the heating mesh surface 11. The lead end 12 extends along the first direction F1 towards the side of the heating mesh surface 11 away from the fiber tube.

[0037] The heating mesh 11, typically made of metal alloy such as nickel-chromium wire or stainless steel mesh, is the component directly used to heat the atomizing liquid. The heating mesh 11 features multiple irregular perforated structures 100, increasing the contact area with the atomizing liquid and improving atomization efficiency. The mesh design prevents localized overheating, resulting in more even heat distribution and reducing the risk of dry burning. The design of the heating mesh 11 being tightly attached to the inner side of the oil-guiding cotton 50 ensures that the atomizing liquid can comprehensively cover the heating area through the capillary action of the oil-guiding cotton 50 fibers, preventing carbonization caused by localized heating without liquid contact on the heating element 10. The pin 12, typically made of nickel or gold-plated copper, connects the heating mesh 11 to the circuitry within the atomizing core, transmitting electrical energy to heat the heating mesh 11. Fixing the pin 12 to the side of the heating mesh 11 away from the fiber tube avoids interfering with the aerosol flow path and also prevents the fiber tube from aging due to heat. In addition, when metal is used in the support tubes currently on the market, the electrode pins that are assembled with it in the atomizer core must be coated with rubber (Teflon) to prevent direct contact between the electrode pins and the support tube, which could lead to a short circuit. However, during the coating process, if the coating is too tight, the clips securing the pins can easily scratch the rubber layer; if the coating is too loose, the heating element 11 can easily deform. The high-temperature resistant plastic inner support tube 20 used in this application is a natural insulator. Therefore, the pins do not need to be coated with rubber during the atomizer core manufacturing process, avoiding the aforementioned problems, preventing resource waste, and simplifying the production process.

[0038] More preferably, the inner support tube 20 and the outer support tube 40 are formed by any one or a combination of tube extrusion, injection molding, high temperature molding, powder sintering, laser cutting and lathe machining.

[0039] Among these methods, pipe extrusion is suitable for inner support tubes 20 or outer support tubes 40 made of PA or PET materials. This molding method can continuously produce highly consistent tubes and is suitable for mass production. In addition, pipe extrusion can also form some complex cross-sections of tubes, such as irregularly shaped tubes with internal oil passages 21. Single-tube extrusion usually requires secondary processing such as laser drilling, and therefore is not suitable for metal supports. Injection molding is also suitable for forming support tubes made of PA or PET materials. Injection molding can form complex structures 100 with oil passages and ventilation grooves 22 in one step, reducing assembly steps. High-temperature molding is suitable for forming support tubes with ceramic fibers or metal as the main material. Powder sintering is suitable for forming porous metal support tubes. Laser cutting can improve the accuracy of the cuts on the internal oil passages 21, external oil passages 41, and ventilation grooves 22, and can process complex structures 100 on the support tube. Lathe machining is suitable for the fine finishing of small batches of metal support tubes, used to correct the roundness of sintered / extruded support tubes to ensure their sealing performance.

[0040] Therefore, by using high-temperature resistant plastic for the inner support tube 20, and ensuring that the heat from the high-temperature aerosol passes through the inner support tube 20 before entering the oil-collecting cotton 30, the inner support tube 20 avoids metal oxidation reactions with the high-temperature aerosol, preventing the precipitation of metal ions. This reduces the harm to the human body caused by metal ions generated during heating of the electronic atomizing core structure 100. Furthermore, the design of using high-temperature resistant plastic for the inner support tube 20 to isolate some of the heat from the high-temperature aerosol from entering the oil-collecting cotton 30 effectively prevents the oil-collecting cotton 30 from softening at high temperatures, thus preventing conduction and pressure relief failure of the atomizing liquid.

[0041] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
