Description

Technical Field

[0001] This utility model relates to the technical field of electronic atomization devices, specifically to a ceramic atomizing core with a U-shaped heating ribbon preheating function. Background Technology

[0002] With social development and technological advancements, electronic atomization devices have become widely used, commonly for atomizing liquids and aerosols to enhance their utilization. The atomizer core, as the core component of these devices, plays a crucial role in the aerosol's flavor and vapor production. Current technologies often utilize highly viscous atomized materials. Without preheating, these materials exhibit poor flowability, hindering their passage through the porous ceramic substrate to the atomization surface, leading to potential dry burning and reduced atomization efficiency. Current ceramic atomizer cores typically employ a heating wire on the atomization surface for preheating and atomization. However, the design and placement of this heating wire within the core are often flawed, resulting in carbon buildup during preheating. Furthermore, the wire's placement on one side of the ceramic substrate leads to unstable bonding, low heat transfer efficiency, and uneven heat distribution, negatively impacting atomization performance and product reliability. Summary of the Invention

[0003] To overcome the shortcomings and deficiencies of existing technologies, the purpose of this utility model is to provide a ceramic atomizing core with a U-shaped heating wire preheating function. The ceramic atomizing core uses a three-dimensional U-shaped heating wire to preheat and atomize the atomized material. The U-shaped heating wire includes an atomizing metal heating wire, a first preheating metal heating wire, and a second preheating metal heating wire. The first and second preheating metal heating wires are embedded in the sidewall of the ceramic atomizing core, allowing for double-sided preheating of the atomized material. When the atomized material is viscous, this improves its fluidity. The atomizing metal heating wire is positioned on the atomizing surface to atomize the liquid conducted to the atomizing surface. The U-shaped heating wire of the ceramic atomizing core is firmly bonded to the ceramic substrate, effectively improving the problems of low heat transfer efficiency and uneven heat transfer, thus enhancing the atomization effect and product reliability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a ceramic atomizing core with a U-shaped heating wire preheating function, comprising a ceramic substrate and a U-shaped heating wire, wherein the ceramic substrate comprises a side wall and a bottom plate connected to the lower end of the side wall, the side wall and the bottom plate forming an accommodating cavity, and the lower end surface of the bottom plate being an atomizing surface;

[0024] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0025] like Figure 1-8 As shown, a ceramic atomizing core with a U-shaped heating wire preheating function includes a ceramic substrate 1 and a U-shaped heating wire 2. The ceramic substrate 1 includes a side wall 11 and a base plate connected to the lower end of the side wall 11. The side wall 11 and the base plate form an accommodating cavity 12. The lower end surface of the base plate is an atomizing surface 13. The side wall 11 includes a front side wall 11, a first side end side wall 11, a rear side wall 11, and a second side end side wall 11 connected end to end. The first side end side wall 11 and the second side end side wall 11 are arranged opposite to each other.

[0026] The U-shaped heating wire 2 includes an atomizing metal heating wire 21, a first preheating metal heating wire 22, a second preheating metal heating wire 23, and two U-shaped electrodes 24. Each U-shaped electrode 24 includes a connecting piece 241 and a first extension arm 242 and a second extension arm 243, the lower ends of which are respectively connected to the front and rear ends of the connecting piece 241. The atomizing metal heating wire 21, the first preheating metal heating wire 22, and the second preheating metal heating wire 23 are connected in parallel.

[0027] The two ends of the atomizing metal heating wire 21 are respectively connected to two connecting pieces 241; the two ends of the first preheating metal heating wire 22 are respectively connected to two first extension arms 242, and the two ends of the second preheating metal heating wire 23 are respectively connected to two second extension arms 243; the first preheating metal heating wire 22 and the first extension arms 242 are embedded in the front sidewall 11 of the ceramic substrate 1; the second preheating metal heating wire 23 and the second extension arms 243 are embedded in the rear sidewall 11 of the ceramic substrate 1, the connecting pieces 241 are disposed on the base plate, and the atomizing metal heating wire 21 is disposed on the atomizing surface 13. The connecting pieces 241 can be embedded in the base plate or attached to the atomizing surface 13.

[0028] In this embodiment, the ceramic atomizing core uses a three-dimensional U-shaped heating wire 2 to preheat and atomize the atomized material. The U-shaped heating wire 2 includes an atomizing metal heating wire 21, a first preheating metal heating wire 22, and a second preheating metal heating wire 23. The first preheating metal heating wire 22 and the second preheating metal heating wire 23 are embedded in the side wall 11 of the ceramic atomizing core, which can preheat the atomized material in the accommodating cavity 12 from both sides. When the atomized material is relatively viscous, it can improve the fluidity of the atomized material. The atomizing metal heating wire 21 is disposed on the atomizing surface 13 to atomize the atomized liquid conducted to the atomizing surface 13. In this embodiment, the U-shaped heating wire 2 of the ceramic atomizing core is firmly bonded to the ceramic substrate 1, which can effectively improve the problems of low heat transfer efficiency and uneven heat transfer of the ceramic atomizing core, and improve the atomization effect and product reliability.

[0029] Furthermore, the first preheating metal heating wire 22 and the second preheating metal heating wire 23 are respectively disposed above the front end and rear end of the atomizing metal heating wire 21 and spaced apart from the atomizing metal heating wire 21. In this embodiment, the atomizing metal heating wire 21 is attached to the atomizing surface 13, and the first preheating metal heating wire 22 and the second preheating metal heating wire 23 are respectively located above both ends of the atomizing metal heating wire 21 and are symmetrical to each other. The first preheating metal heating wire 22 and the second preheating metal heating wire 23 are both perpendicular to the atomizing surface 13 or both are inclined. The first preheating metal heating wire 22, the second preheating metal heating wire 23 and the atomizing metal heating wire 21 are arranged in a U-shaped structure. The first preheating metal heating wire 22, the second preheating metal heating wire 23 and the atomizing metal heating wire 21 do not contact each other, and the three are connected in parallel, which helps to improve heat transfer efficiency and heat transfer uniformity.

[0030] Furthermore, the resistance of the atomizing metal heating wire 21 is less than that of the first preheating metal heating wire 22 and the second preheating metal heating wire 23. In this invention, the U-shaped heating wire 2 has the heating wires on both sides, namely the first preheating metal heating wire 22 and the second preheating metal heating wire 23, designed with higher resistance; in this embodiment, the resistance is preferably greater than 3Ω. The middle heating wire, namely the atomizing metal heating wire 21, is designed with a lower resistance than the heating wires on both sides. This is to reduce the power of the heating wires on both sides, allowing them to be used only for preheating the atomized material, preventing high temperatures from damaging the e-liquid, while allowing the middle heating wire used for atomization to retain greater power for better atomization.

[0031] Furthermore, the atomizing metal heating wire 21, the first preheating metal heating wire 22, and the second preheating metal heating wire 23 are all in an arc shape. In other embodiments of this utility model, the atomizing metal heating wire 21, the first preheating metal heating wire 22, and the second preheating metal heating wire 23 are all in a mesh shape or other shapes.

[0032] Furthermore, the atomizing metal heating wire 21 includes multiple sequentially connected bow-shaped atomizing heating sections 212. Each atomizing heating section 212 has an upwardly extending extension piece 211 at both its front and rear ends. The extension piece 211 extends into the front or rear sidewall 11 of the ceramic substrate 1 and is spaced apart from the first preheating metal heating wire 22 or the second preheating metal heating wire 23. Due to this structure, the extension piece 211 is embedded in the ceramic substrate 1, forming a tight bond. During use, the extension piece 211 can generate heat, improving the heating uniformity of the ceramic atomizing core. The longitudinal section of the extension piece 211 is T-shaped or 7-shaped.

[0033] In this embodiment, when the ceramic atomizing core is used, the atomized material enters the receiving cavity 12 from the upper part of the ceramic substrate 1. After being preheated by the first preheating metal heating wire 22 and the second preheating metal heating wire 23, the resulting atomized liquid penetrates from the upper surface of the base plate to the atomizing surface 13 for atomization. In this embodiment, the longitudinal section of the ceramic substrate 1 is an inverted U-shape. The ceramic substrate 1 can also be configured as a cylindrical cup, a rectangular cup, a triangular cup, or other shapes as needed.

[0034] Furthermore, the atomizing metal heating wire 21, the first preheating metal heating wire 22, and the second preheating metal heating wire 23 are all nickel-chromium alloy heating wires, iron-chromium-aluminum heating wires, stainless steel heating wires, or titanium alloy heating wires. These heating wires have advantages such as high heat transfer efficiency and long service life. This invention allows for the selection of appropriate metal heating wires according to different needs. The atomizing metal heating wire 21, the first preheating metal heating wire 22, and the second preheating metal heating wire 23 can be made of the same material or different materials.

[0035] Furthermore, the lower end surface of the base plate is a plane. In this embodiment, the lower end surface of the base plate is set as a plane and serves as the atomizing surface 13, which helps to securely install the atomizing metal heating wire 21 onto the atomizing surface 13 and facilitates the installation and use of the ceramic atomizing core in the electronic atomizing device.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
