Description

Technical Field

[0001] This utility model relates to the field of cigarette substitute technology, and in particular to an electronic cigarette atomizing core and atomizer. Background Technology

[0002] Electronic atomizing devices are electronic products that mimic cigarettes, atomizing e-liquid into vapor for users to inhale. Due to their similar taste and ease of use to cigarettes, electronic atomizing devices have been rapidly promoted and used.

[0003] Existing electronic cigarettes typically include a battery unit and an atomizer. The atomizer contains an atomizing coil and an e-liquid reservoir. The e-liquid reservoir is filled with e-liquid. The battery unit powers the atomizer, causing the atomizing coil to heat up and generate high temperatures, which atomize the e-liquid into vapor for the user to inhale.

[0004] When an e-cigarette produces vapor, the moisture and other substances in the vapor condense into liquid due to the temperature difference with the atomizing chamber, forming condensate. This condensate is either inhaled along with the vapor during inhalation, affecting the vaping experience, or it gathers into droplets and is reabsorbed and atomized by the atomizing coil, also affecting the vaping experience.

[0005] In addition to the condensate produced by high-temperature atomization, e-liquid products also need to consider leakage problems caused by temperature and air pressure changes during transportation. If e-liquid leaks out, it will also leak out of the atomizer through the atomization chamber, or be drawn into the user's mouth when vaping, affecting the vaping experience; it may even affect the exhaust of the atomizer coil due to leakage. Utility Model Content

[0006] Therefore, it is necessary to provide an electronic cigarette atomizer core and atomizer that can absorb condensate and leakage, and facilitate exhaust, in order to address the above problems.

[0007] An electronic cigarette atomizing core includes a tubular support, an atomizing component, a first three-dimensional cotton, a second three-dimensional cotton, a sleeve, and a center rod. The atomizing component is disposed on the inner wall of the tubular support and sleeved on the center rod. The center rod penetrates the tubular support, and the tubular support wall has an oil guide hole that communicates with the atomizing component. The first three-dimensional cotton and the second three-dimensional cotton are axially disposed within the sleeve and spaced apart. The sleeve wall has an oil inlet that communicates with the first three-dimensional cotton. The first three-dimensional cotton is sleeved on the outside of the tubular support, and the second three-dimensional cotton is sleeved on the center rod. One end of the tubular support abuts against the end of the second three-dimensional cotton. The center rod is detachably disposed within the atomizing core.

[0008] In one embodiment, the axial distance between the first three-dimensional cotton and the second three-dimensional cotton is 2mm-4mm.

[0009] In one embodiment, the first three-dimensional cotton is interference-fitted with the tubular support, the second three-dimensional cotton is spaced apart from the central tube, the outer diameter of the tubular support is d1, the diameter of the central hole of the second three-dimensional cotton is d2, and the diameter of the central rod is d3, wherein d1 > d2 > d3.

[0010] In one embodiment, the first three-dimensional cotton is a moistened three-dimensional cotton that has been humidified.

[0011] In one embodiment, the oil guide holes are circumferentially distributed on the wall surface of the tubular support.

[0012] In one embodiment, the tubular support wall is provided with four oil guide holes.

[0013] In one embodiment, the casing wall is uniformly provided with at least two oil inlet holes.

[0014] In one embodiment, it further includes a stop ring and a fixing seat. The stop ring is inserted inside the sleeve and abuts against one end of the first three-dimensional cotton. The fixing seat is inserted inside the tubular support and the fixing seat and the stop ring are located at the same end. The peripheral wall of the fixing seat has at least two wire passage grooves.

[0015] In one embodiment, the atomizing component includes a heating mesh and an oil-guiding cotton, the heating mesh being disposed in conjunction with the central rod, and the oil-guiding cotton covering the heating mesh and being disposed in conjunction with the inner wall of the tubular support.

[0016] An atomizer includes a housing, a base, and an atomizing core. The base is inserted into one end of the housing, and the atomizing core is placed in a cavity formed by the housing and the base, dividing the cavity into an oil storage chamber and an atomizing chamber. When the distance L between the outer wall of the sleeve and the inner wall of the oil storage chamber is ≥2mm, four oil inlets are provided circumferentially on the sleeve wall. When the distance L between the outer wall of the sleeve and the inner wall of the oil storage chamber is <2mm, no oil inlet is provided at L <2mm. The oil inlets are provided at L ≥2mm and are provided circumferentially on the sleeve.

[0017] The aforementioned electronic cigarette atomizing coils and atomizers have at least the following advantages:

[0018] This atomizer core features a first 3D cotton layer surrounding the atomizing component, with a second 3D cotton layer spaced apart from it. E-liquid is absorbed by the first 3D cotton layer and then atomized by the atomizing component. The first 3D cotton layer serves to absorb e-liquid and provide ventilation. The spaced-apart second 3D cotton layer allows for ventilation between the first and second 3D cotton layers and the outside environment. Furthermore, the space between the first and second 3D cotton layers prevents e-liquid absorbed by the first layer from being conducted to or soaking into the second layer. If the first 3D cotton layer leaks due to pressure or temperature changes, the leaked e-liquid can flow through the spaced-apart cotton layer to the second layer for absorption, preventing leakage from the atomizer core. Condensate produced by the high-temperature atomization of the atomizer core can also be absorbed by the second 3D cotton layer, without affecting the taste or user experience. Moreover, the condensate will not flow back to the first 3D cotton layer for repeated heating and atomization, ensuring consistent taste and high e-liquid fidelity. Attached Figure Description

[0026] Please see Figure 1 This is a schematic diagram of the structure of an electronic cigarette atomizing core in one embodiment.

[0027] For details, please refer to Figure 2 , Figure 3 An electronic cigarette atomizing core 10 includes a tubular support 11, an atomizing component 12, a first three-dimensional cotton 13, a second three-dimensional cotton 14, a sleeve 15, and a center rod 16. The atomizing component 12 is disposed on the inner wall of the tubular support 11 and is sleeved on the center rod 16, which penetrates the tubular support 11. The tubular support 11 has an oil guide hole 112 on its wall, which communicates with the atomizing component 12. The first three-dimensional cotton 13 and the second three-dimensional cotton 14 are axially disposed inside the sleeve 15 and spaced apart from each other. The sleeve 15 has an oil inlet hole 152 on its wall, which communicates with the first three-dimensional cotton 13. The first three-dimensional cotton 13 is sleeved on the outside of the tubular support 11, and the second three-dimensional cotton 14 is sleeved on the center rod 16. One end of the tubular support 11 abuts against the end of the second three-dimensional cotton 14. The center rod 16 is detachably disposed within the atomizing core 10.

[0028] The atomizing core 10 has a first three-dimensional cotton 13 placed outside the atomizing component 12, and a second three-dimensional cotton 14 placed at intervals between the first three-dimensional cotton 13. E-liquid is absorbed by the first three-dimensional cotton 13 and then atomized by the atomizing component 12. The first three-dimensional cotton 13 serves to absorb e-liquid and provide ventilation. The spaced second three-dimensional cotton 14 allows for ventilation between the first three-dimensional cotton 13 and the outside environment. Furthermore, because of the gap between the first three-dimensional cotton 13 and the second three-dimensional cotton 14, the e-liquid absorbed by the first three-dimensional cotton 13... The first three-dimensional cotton 13, which absorbs e-liquid, will not conduct or soak into the second three-dimensional cotton 14. When the first three-dimensional cotton 13, which absorbs e-liquid, leaks due to pressure or temperature changes, the leaked e-liquid can flow through the gap to the second three-dimensional cotton 14 for absorption, without leaking out of the atomizer core 10. The condensate produced by the high-temperature atomization of the atomizer core 10 can also be absorbed by the second three-dimensional cotton 14, without affecting the taste and user experience. Moreover, the condensate will not flow into the first three-dimensional cotton 13 for repeated heating and atomization, and the flavor will not change due to the mixing of condensate, ensuring the consistency of the taste and the high fidelity of the e-liquid.

[0029] For details, please refer to Figure 2The first three-dimensional cotton 13 is separated from the atomizing component 12 by a tubular support 11 and is connected by an oil guide hole 112. The atomizing component 12 contacts the first three-dimensional cotton 13 through the oil guide hole 112 to absorb e-liquid, while the first three-dimensional cotton 13 connects with the e-liquid in the atomizer through the oil inlet hole 152 of the sleeve 15 to absorb e-liquid. The upper end of the tubular support 11 is higher than the end face of the first three-dimensional cotton 13, so that the end of the tubular support 11 contacts the end of the second three-dimensional cotton 14. This allows there to be a section without any filling between the tubular support 11 and the sleeve 15, forming a gap between the first three-dimensional cotton 13 and the second three-dimensional cotton 14. The tubular support 11 contacts one end of the second three-dimensional cotton 14, allowing airflow to pass through the first three-dimensional cotton 13 and the second three-dimensional cotton 14, but the e-liquid in the first three-dimensional cotton 13 cannot flow out of the tubular support 11 and the second three-dimensional cotton 14. During transportation or storage, the center rod 16 is inserted into the atomizing core 10. When the user needs to use it, the center rod 16 is pulled out, which allows the atomizer's mouthpiece to connect with the atomizing core 10, thus achieving high-temperature atomization.

[0030] In this embodiment, the axial distance between the first three-dimensional cotton 13 and the second three-dimensional cotton 14 is 2mm-4mm. During the transportation or storage of the atomizer filled with e-liquid in the oil storage chamber, changes in temperature and air pressure can disrupt the pressure balance between the e-liquid and air in the oil storage chamber, leading to oil leakage. Setting a distance of 2mm-4mm between the first three-dimensional cotton 13 and the second three-dimensional cotton 14 facilitates exhaust, ensures stable oil supply, and prevents condensate from flowing back onto the atomizing component 12, thereby improving the service life of the atomizing component 12.

[0031] In this embodiment, the first three-dimensional cotton 13 is interference-fitted with the tubular support 11, ensuring a stable fit between the first three-dimensional cotton 13 and the tubular support 11 even after absorbing e-liquid. This prevents the tubular support 11 and the sleeve 15 from becoming too loose after absorbing e-liquid, thus avoiding insufficient compression to support the weight of the e-liquid and causing the first three-dimensional cotton 13 to shift. The gap between the second three-dimensional cotton 14 and the central tube facilitates the discharge of gas through this gap during exhaust. Specifically, the outer diameter of the tubular support 11 is d1, the diameter of the central hole of the second three-dimensional cotton 14 is d2, and the diameter of the central rod 16 is d3, where d1 > d2 > d3.

[0032] In this embodiment, the first three-dimensional cotton 13 is a moistened three-dimensional cotton that has been lubricated. After lubrication, the first three-dimensional cotton 13 is assembled into the atomizer core 10, which makes the air bubbles in the oil storage chamber smaller, preventing larger air bubbles from carrying out more e-liquid and leaking out during transportation and storage, thus playing a role in preventing oil leakage. The second three-dimensional cotton 14 does not require lubrication and can absorb the small amount of e-liquid and condensate that seeps out when the atomizer is inverted, preventing oil accumulation in the atomizer core 10.

[0033] In this embodiment, the oil guide holes 112 are evenly distributed around the wall of the tubular support 11, which facilitates the atomizing component 12 to uniformly absorb e-liquid from the first three-dimensional cotton 13, thereby making the oil guide of the atomizing component 12 uniform and the atomization supply stable, thus stabilizing the taste and improving the service life of the atomizing component 12.

[0034] The tubular support 11 has four oil guide holes 112 on its wall surface, which helps to ensure the strength of the tubular support 11 while guiding oil evenly.

[0035] Please see Figure 3 In this embodiment, the atomizing component 12 includes a heating mesh 122 and an oil-guiding cotton 124. The heating mesh 122 is disposed in conjunction with the central rod 16, and the oil-guiding cotton 124 covers the heating mesh 122 and is disposed in conjunction with the inner wall of the tubular support 11. That is, the sleeve 15, the first three-dimensional cotton 13, the tubular support 11, the oil-guiding cotton 124, the heating mesh 122 and the central rod 16 are arranged in sequence.

[0036] In this embodiment, the atomizing core 10 also includes a stop ring 17 and a fixing seat 18. The stop ring 17 is inserted inside the sleeve 15 and abuts against one end of the first three-dimensional cotton 13. The fixing seat 18 is inserted inside the tubular support 11, and the fixing seat 18 and the stop ring 17 are located at the same end. The fixing seat 18 has at least two wire passage grooves 182 on its peripheral wall. The stop ring 17 abuts against one end of the first three-dimensional cotton 13, which helps to maintain the position of the first three-dimensional cotton 13 and prevents the movement of the first three-dimensional cotton 13 from affecting the oil guiding and exhaust, and even prevents the first three-dimensional cotton 13 from falling out of the sleeve 15 due to gravity after absorbing oil. The wire passage grooves 182 of the fixing seat 18 can be used to fix the two wires of the heating mesh 122, so that the position of the heating mesh 122 is fixed during assembly, and the preset atomization effect can be achieved. Of course, more wire passage grooves 182 can be made on the peripheral wall of the fixing seat 18, which is conducive to quick assembly.

[0037] This application also provides an atomizer, including a housing, a base, and an atomizing core 10. The base is inserted into one end of the housing, and the atomizing core 10 is placed in the cavity formed by the housing and the base. The atomizing core 10 divides the cavity into an oil storage chamber and an atomizing chamber. The atomizing core 10 is any of the atomizing cores described above. Since this atomizing core 10 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0038] The sleeve 15 has at least two oil inlet holes 152 evenly distributed on its wall surface. When the distance L between the outer wall of the sleeve 15 and the inner wall of the oil storage chamber is ≥2mm, four oil inlet holes 152 are evenly distributed around the circumference of the sleeve 15. When the distance L between the outer wall of the sleeve 15 and the inner wall of the oil storage chamber is <2mm, no oil inlet hole 152 is provided at L <2mm. The oil inlet holes 152 are provided at locations L ≥2mm, and at least two are evenly distributed around the circumference of the sleeve 15. Not providing oil inlet holes 152 at locations L <2mm can prevent oil leakage due to thermal shock when the atomizer is laid flat.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
