Description

Technical Field

[0001] This application relates to the field of electronic cigarettes, and more particularly to a housing for an atomizing core and an electronic cigarette. Background Technology

[0002] The primary function of the atomizer coil in an e-cigarette is to heat the e-liquid and convert it into inhalable vapor. The atomizer coil typically consists of a shell, a heating coil, and a wicking material (such as cotton). The heating coil and wicking material are housed inside the shell. When the user inhales, the battery powers the coil, causing it to heat up. The e-liquid absorbed by the wicking material is then atomized, forming a fine vapor. The performance of the atomizer coil directly affects the flavor, vapor production, and lifespan of the e-cigarette.

[0003] Existing atomizer coil shells are typically simple cylindrical structures, which are prone to cracking or breaking under high temperatures or airflow impact. Therefore, there is a need for a shell for the atomizer coil that enhances its overall strength. Utility Model Content

[0031] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0032] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0033] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] Please see Figures 1-5 This application provides an atomizer core housing 100, comprising: a body 10, a placement hole 20, a first protrusion 30, and a second protrusion 40. The placement hole 20 extends through the body 10 along an axial direction F1 and is used to place an oil guide 21. The first protrusion 30 is integrally formed with the body 10, and the first protrusion 30 is wound around the body 10 and located on the axis of the body 10. The second protrusion 40 is integrally formed with the body 10, and the second protrusion 40 is wound around the body 10 and located on the lower axis of the body 10. The first protrusion 30 and the second protrusion 40 are located at the ends opposite to the placement hole 20.

[0035] Specifically, the main body 10 serves as the basic structure of the atomizer core shell, providing necessary support and protection to ensure the stable operation of the internal heating coil and wicking material. Its materials are typically chosen from high-temperature resistant and corrosion-resistant metals or alloys to adapt to the working environment of the electronic cigarette 200.

[0036] The placement hole 20 extends through the interior of the body 10 along the axial direction F1, and serves as the space for the oil guide 21 (such as cotton). The design of the placement hole 20 must ensure that the oil guide 21 can fit tightly, while facilitating the penetration and heating of e-liquid.

[0037] The first protrusion 30 is integrally formed with the body 10, wrapped around the body 10 and located on the axis, mainly serving to enhance the overall strength of the shell. By increasing the thickness and rigidity of the shell, the first protrusion 30 can effectively resist deformation and cracks under high temperature and airflow impact, improving the durability of the atomizing core.

[0038] The second protrusion 40 is also integrally formed with the body 10, but is located on the lower axis of the body 10, and together with the first protrusion 30, it forms a reinforcing structure for the outer shell. The design of the second protrusion 40 not only enhances the strength of the outer shell, but may also be used for fixing and connecting with other components (such as the main body of the electronic cigarette 200), thereby improving the stability of the overall structure.

[0039] The first protrusion 30 and the second protrusion 40 are located at the end opposite to the placement hole 20. This design ensures efficient use of space inside the housing and avoids interference between the protrusion structure and the oil guide 21 and the heating coil. At the same time, the distribution of the first protrusion 30 and the second protrusion 40 along the axial direction F1 enables effective stress dispersion when the housing is subjected to external forces, further improving the strength and durability of the housing.

[0040] In one specific embodiment, the body 10 includes a large-diameter portion 11, a small-diameter portion 12, and a transition portion 13 distributed along the axial direction F1. One end of the transition portion 13 is connected to the large-diameter portion 11, and the other end of the transition portion 13 is connected to the small-diameter portion 12. The second protrusion 40 is wrapped around the large-diameter portion 11, and the first protrusion 30 is wrapped around the small-diameter portion 12.

[0041] Specifically, the large-diameter portion 11, as one of the main parts of the outer shell, provides sufficient space to accommodate the wicking element 21 (such as cotton) and the heating coil. Its larger diameter helps to increase the strength and stability of the outer shell, while ensuring that the wicking element 21 can fully absorb and store e-liquid, providing an ample supply of e-liquid for the subsequent atomization process.

[0042] The small-diameter portion 12 is used for connection with the main body of the electronic cigarette 200, or as an airflow channel. Its smaller diameter helps reduce airflow resistance and improve atomization efficiency. In addition, the design of the small-diameter portion 12 can save material costs while maintaining the overall strength and stability of the shell.

[0043] The transition section 13 connects the large-diameter section 11 and the small-diameter section 12, ensuring the integrity and smoothness of the casing. The transition section 13 incorporates adjustments to parameters such as angle and curvature to adapt to the needs of different electronic cigarette products. The presence of the transition section 13 makes the casing more structurally flexible and adaptable.

[0044] The second protrusion 40 is wrapped around the large-diameter portion 11, enhancing the strength of the outer shell in the area of ​​the large-diameter portion 11. By increasing the thickness and rigidity of the outer shell, the second protrusion 40 can effectively resist deformation and cracking under high temperature and airflow impact. At the same time, the second protrusion 40 can also be used for fixing and connecting with other components (such as the connection part of the electronic cigarette 200 body), improving the stability of the overall structure.

[0045] The first protrusion 30 is wrapped around the small-diameter portion 12, enhancing the strength of the housing in the area of ​​the small-diameter portion 12. The design of the first protrusion 30 may also take into account the matching and connection requirements with the main body of the electronic cigarette 200 or other components. By increasing the rigidity and stability of the housing in the area of ​​the small-diameter portion 12, the first protrusion 30 helps ensure that the electronic cigarette 200 maintains good atomization performance even with prolonged use and frequent e-liquid replacements.

[0046] The combined design of the large-diameter portion 11, the small-diameter portion 12, and the transition portion 13 makes the shell more structurally balanced and stable. By adjusting the size and shape parameters of these parts, it can adapt to the needs of different electronic cigarette 200 products. At the same time, the design of the second protrusion 40 and the first protrusion 30 respectively surrounding the large-diameter portion 11 and the small-diameter portion 12 not only enhances the strength of the shell, but also makes the shell more structurally flexible and adaptable.

[0047] In one specific embodiment, the placement hole 20 sequentially extends through the large-diameter portion 11, the small-diameter portion 12, and the transition portion 13. The oil guide 21 is located within the large-diameter portion 11.

[0048] Specifically, the placement hole 20 passes sequentially through the large-diameter portion 11, the small-diameter portion 12, and the transition portion 13. This design ensures that the wicking component 21 can be smoothly installed and fit tightly inside the outer shell. The placement hole 20 starts from the large-diameter portion 11 and passes sequentially through the small-diameter portion 12 and the transition portion 13. This layout not only considers the ease of installation of the wicking component 21 but also ensures that e-liquid can smoothly permeate from the outside into the wicking component 21. At the same time, the placement hole 20 penetrates the entire body 10, making the outer shell structurally more complete and stable.

[0049] The large-diameter portion 11 provides ample space to accommodate the wicking element 21, ensuring that the wicking element 21 can fully absorb and store e-liquid. The design of the wicking element 21 located within the large-diameter portion 11 also contributes to improved atomization efficiency, as the e-liquid can be distributed more evenly on the wicking element 21, thereby increasing the contact area with the heating coil. Furthermore, the design of the large-diameter portion 11 also considers the ease of replacement and maintenance of the wicking element 21, allowing users to easily remove and replace it.

[0050] In one specific embodiment, the first protrusion 30 and the second protrusion 40 are disposed parallel to each other on the axial direction F1 of the body 10. The first protrusion 30 and the second protrusion 40 are annular.

[0051] Specifically, the parallel arrangement and annular design of the first protrusion 30 and the second protrusion 40 together constitute the reinforced structure of the housing. This design not only enhances the strength and stability of the housing but also optimizes its heat dissipation performance. Through the parallel arrangement, the first protrusion 30 and the second protrusion 40 can form effective support and protection in the axial direction F1, preventing deformation or cracking of the housing. The annular design further enhances this support and protection while optimizing heat dissipation performance.

[0052] Furthermore, the uniform winding of the annular protrusions helps improve the uniformity and consistency of the shell, thus ensuring that the e-cigarette 200 maintains stable atomization and a good flavor even with prolonged use and frequent e-liquid replacements. This design also helps reduce material waste and processing costs during production, as the annular protrusions allow for more efficient material utilization and simplify the manufacturing process.

[0053] In one specific embodiment, the outer shell 100 of the atomizing core includes at least two first protrusions 30. A groove 31 is formed between the two first protrusions 30, and a sealing ring is fitted inside the groove 31.

[0054] Specifically, by increasing the number of the first protrusions 30, the housing gains additional structural support and stability. These protrusions not only enhance the strength of the housing but also provide the necessary structural foundation for the subsequent installation of the sealing ring.

[0055] A groove 31 is formed between the two first protrusions 30. The design of the groove 31 is crucial for installing the sealing ring. It ensures that the sealing ring fits tightly against the outer shell, effectively preventing e-liquid or other liquids from leaking into other parts of the electronic cigarette 200. The depth and width of the groove 31 are typically precisely designed according to the size and material of the sealing ring to ensure optimal sealing.

[0056] The sealing ring is typically made of an elastic material, such as rubber or silicone. It deforms under pressure, thus tightly filling the tiny gaps between the groove 31 and adjacent components. This design not only improves the seal of the housing but also helps reduce airflow resistance, enhancing the draw resistance of the electronic cigarette 200.

[0057] In one specific embodiment, the sealing ring is fitted inside the groove 31, and the outer shell 100 of the atomizing core is fitted with at least one of the sealing rings.

[0058] Specifically, the sealing ring is fitted within the groove 31, further emphasizing the tight fit between the sealing ring and the groove 31. The sealing ring is designed to tightly fill the groove 31, thereby preventing liquids (such as e-liquid) from leaking out of the outer shell. This design not only improves the safety of the electronic cigarette 200 but also ensures a good user experience.

[0059] The fact that the outer shell 100 of the atomizer coil is fitted with at least one sealing ring means that there is at least one location on the shell where a sealing ring is installed to ensure a tight seal at that location. However, in practical applications, depending on the design and performance requirements of the e-cigarette 200, multiple sealing rings may be fitted on the shell to further enhance the sealing effect. The use of multiple sealing rings provides an extra layer of protection, preventing liquid leakage even if one of the sealing rings fails.

[0060] In one specific embodiment, the outer shell 100 of the atomizing core includes a fastener 50, which is sleeved on the body 10. The fastener 50 abuts against the first protrusion 30, and the abutting portion of the fastener 50 is located in the groove 31.

[0061] Specifically, the snap-fit ​​component 50 is designed to fit snugly onto the body 10, thereby ensuring the assembly stability and structural integrity of the housing. This design not only simplifies the assembly process but also improves production efficiency.

[0062] The abutting portion of the latching member 50 can make close contact with the first protrusion 30, thereby further enhancing the stability of the housing. This abutting relationship helps prevent the housing from loosening or deforming during use.

[0063] The innovative design of positioning the abutment portion of the snap-fit ​​element 50 within the groove 31 not only improves the sealing performance of the housing but also optimizes the assembly process. Because the abutment portion is located within the groove 31, it can form an additional sealing layer with the sealing ring, further preventing liquid leakage. Simultaneously, this design also makes it easier to align and secure the snap-fit ​​element 50 during installation.

[0064] Furthermore, it helps reduce production costs. Since the snap-fit ​​component 50 can fit snugly onto the body 10 and form a stable connection with the first protrusion 30 and the groove 31, a stable assembly effect can be achieved without additional fasteners or adhesives. This reduces material and processing costs and improves production efficiency.

[0065] In one specific embodiment, the large-diameter portion 11 has an oil guide hole 60, which is located at one end near the transition portion 13 and extends through the placement hole 20 to the outside. A plurality of oil guide holes 60 are evenly distributed around the axis of the placement hole.

[0066] Specifically, the wicking hole 60 is located at the end of the large-diameter portion 11 near the transition portion 13. This has several advantages. First, it allows e-liquid to enter the placement hole 20 more easily from the outside, as this location is typically closer to the e-liquid reservoir of the e-cigarette 200. Second, its proximity to the transition portion 13 helps the e-liquid flow smoothly to the atomizer coil after entering the placement hole 20, since the transition portion 13 is usually designed with a structure to guide the flow of e-liquid.

[0067] The design of the wicking hole 60 ensures that e-liquid can enter the placement hole 20 directly from the outside, without needing to pass through other complex channels or structures. This direct and simple design not only improves the efficiency of e-liquid delivery but also helps reduce the risk of clogging and leakage.

[0068] To further improve the e-liquid delivery efficiency and atomization effect, multiple wicking holes 60 should be evenly distributed around the axis of the placement hole 20. This design ensures that the e-liquid can enter the placement hole 20 evenly from all directions, thus avoiding uneven atomization caused by uneven e-liquid distribution. At the same time, the evenly distributed wicking holes 60 also help improve the overall performance and stability of the electronic cigarette 200.

[0069] In one specific embodiment, the atomizing core shell is a one-piece stamped structure.

[0070] Specifically, stamping integral forming is a manufacturing process that uses a mold to stamp metal sheets into the desired shape. This process can stamp various parts of the shell (such as the large-diameter part 11, the transition part 13, the small-diameter part 12, etc.) in one go, without the need for subsequent welding or assembly steps. Therefore, it greatly improves production efficiency and reduces production costs.

[0071] Because stamping and molding can complete the manufacturing of the outer shell in one go, the production cycle is significantly shortened. Compared with traditional welding or assembly processes, this process can produce a large number of atomizer core shells much faster.

[0072] The one-piece stamping process reduces material waste and processing steps, thus lowering production costs. Furthermore, it reduces equipment investment costs because no additional welding or assembly equipment is required.

[0073] The unibody stamping design results in a more compact and robust structure. Because the various parts are formed in a single stamping process, the connections between them are stronger, reducing the likelihood of loosening or deformation. This contributes to the overall stability and durability of the e-cigarette 200.

[0074] An electronic cigarette 200 (not shown in the figure) includes all the structures of the outer shell 100 of the atomizing core described above. Since this embodiment includes all the features of the above embodiments, this embodiment has all the beneficial effects of the above embodiments, which will not be described again here.

[0075] Therefore, the housing 100 of the atomizing core provided above enhances the overall strength of the housing by means of the first protrusion 30 and the second protrusion 40 integrally formed with the body 10, thereby improving the durability of the housing 100 of the atomizing core.

[0076] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
