Description

Technical Field

[0001] This utility model relates to the technical field of electronic cigarette atomizing cores, and in particular to a perforated heating element type ceramic atomizing core. Background Technology

[0002] Ceramic atomizer cores, as the core components of e-cigarette atomizers, are widely used in the heating and atomization process of e-cigarettes. Their performance directly affects the atomization efficiency, flavor experience, and product lifespan. With the continuous development of the e-cigarette market, users are increasingly demanding faster heating, more uniform heat generation, more stable temperature control, and greater structural reliability from atomizer cores.

[0003] Referring to the existing Chinese patent with publication number CN219877478U, a porous ceramic heating element is disclosed, belonging to the field of electronic cigarette technology. It includes a porous ceramic tube, a heating mesh, and pins. The inner wall of the porous ceramic tube is provided with a heating mesh, and adjacent heating meshes are connected in parallel. The heating mesh is provided with solder joints, and two pins are symmetrically arranged on the solder joints of the mesh, and the two pins are parallel to each other.

[0004] However, the above-mentioned ceramic heating cores still have the following shortcomings: On the one hand, the existing heating mesh structure is relatively simple, usually consisting of heating resistance wires arranged in series, with hexagonal mesh holes. This not only makes the structure complex but also limits the flexible design of the heating path, resulting in uneven temperature distribution and easy occurrence of local overheating or large temperature differences, affecting the atomization effect and user experience. On the other hand, the pin arrangement is simple, usually welded to the heating mesh in a parallel and symmetrical manner, lacking mounting through holes or positioning structures, resulting in low assembly accuracy, poor connection stability, and easy occurrence of poor electrical contact. In addition, the ceramic tube body is mostly a straight prism or honeycomb structure, and there is a lack of a reasonable transition structure between the inner wall and the bottom surface of the cavity, which easily forms dead corners for liquid stagnation, affecting the sealing performance and uniform liquid atomization. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a perforated heating element type ceramic atomizing core to solve the problems of simple heating structure, unstable pin connection, uneven conduction of atomizing liquid and poor heat dissipation efficiency in the prior art.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a perforated heating element type ceramic atomizing core, including a ceramic body, a receiving cavity for containing atomizing liquid is opened on the upper part of the ceramic body, and a heating mesh is embedded in the bottom area of ​​the ceramic body;

[0007] In the ceramic body below the heating mesh, two mounting through holes for inserting pins are symmetrically arranged with the center of the heating mesh as the axis of symmetry. The pins are connected to the heating mesh after being inserted through the mounting through holes.

[0008] The heating mesh has pin connection ends at both ends and an S-shaped heating area in the middle. The heating area consists of multiple parallel strip heating elements. Adjacent strip heating elements are connected end to end through bending parts to form a continuous heating path. Each strip heating element is uniformly provided with an array of heat dissipation holes. The overall structure of the heating mesh is arranged symmetrically along the central axis.

[0009] In a preferred embodiment of this invention, the pins are connected to each other by soldering points located at the pin connection ends.

[0010] As a preferred embodiment of this utility model, the front and rear side walls of the receiving cavity are both perpendicular to the bottom surface and have the same size, and the left and right side walls of the receiving cavity are opposite to each other and have the same size, forming an angle of 108° with the bottom surface respectively.

[0011] As a preferred embodiment of this utility model, the left and right side walls of the receiving cavity are provided with an arc transition structure between the cavity and the bottom surface.

[0012] As a preferred embodiment of this utility model, the heat dissipation holes are circular through holes arranged in a regular array on each heat-generating element.

[0013] As a preferred technical solution of this utility model, the heating element and the bending part are integrally sintered to form a continuous conductive path.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The heating mesh of this utility model adopts an S-shaped wiring structure and is composed of multiple parallel strip-shaped heating elements. Adjacent heating elements are continuously connected through bending sections to form a continuous and regular heating path. Compared with the traditional hexagonal heating mesh, this structure has a clearer conductive path and a more uniform heat field distribution, which can effectively avoid local overheating or large temperature differences, and improve atomization stability and taste consistency.

[0016] 2. The heating mesh of this utility model has centrally symmetrically arranged mounting through holes at the bottom, which facilitates the insertion and fixing of pins and avoids the problem of easy loosening in the traditional parallel welding method; the pins are reliably welded through the welding points set at the pin connection ends, which enhances the overall structural stability and electrical connection reliability and reduces the failure rate.

[0017] 3. The front and rear side walls of the receiving cavity of this utility model are vertically arranged, and the left and right side walls form a 108° angle with the bottom surface. The bottom corner is provided with an arc transition structure, which effectively avoids the formation of dead corners where liquids stagnate in the corners of the cavity, helps the liquid to flow and atomize fully, and improves the sealing performance and cleanliness.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figure 1-6 As shown, this embodiment provides a perforated heating element type ceramic atomizing core, including a ceramic body 1. A receiving cavity 4 is formed on the upper part of the ceramic body 1 to hold the atomizing liquid, temporarily storing the liquid to be atomized. A heating mesh 3 is embedded in the bottom region of the ceramic body 1, which is used to heat the atomizing liquid and achieve the atomization function.

[0028] In the ceramic body 1 below the heating mesh 3, two mounting through holes 5 are symmetrically arranged with the center of the heating mesh 3 as the axis of symmetry, for inserting pins 2. After the pins 2 are inserted through the mounting through holes 5, they are electrically connected to the heating mesh 3, thereby realizing the conduction between the external power supply and the heating element. The connection method is to set a solder point 305 at the pin connection end 301, and fix the pins 2 and the heating mesh 3 through the solder point 305 to conduct electricity. The structure is firm and has good conductivity.

[0029] The heating mesh 3 has an overall structure arranged symmetrically along its central axis. The heating mesh 3 includes pin connection ends 301 at both ends and a heating zone 302 with an S-shaped routing in the middle. The heating zone 302 is composed of multiple parallel strip-shaped heating elements 303, with adjacent strip-shaped heating elements 303 connected end-to-end by bending portions to form a continuous conductive heating path. Each strip-shaped heating element 303 has multiple uniformly distributed heat dissipation holes 304. The heat dissipation holes 304 are circular through holes, arranged in a regular array on the heating element 303, which facilitates the release of heat during heating and also helps the atomized liquid evaporate evenly, improving atomization efficiency.

[0030] Furthermore, to improve the flow characteristics and structural stability of the atomizing liquid within the receiving cavity 4, the front and rear sidewalls of the receiving cavity 4 are both perpendicular to the bottom surface and have the same dimensions, while the left and right sidewalls are symmetrically arranged and form a 108° angle with the bottom surface. To prevent liquid accumulation and improve the flow guiding effect, an arc-shaped transition structure 401 is also provided between the left and right sidewalls of the receiving cavity 4 and the bottom surface, making the structural transition smooth, avoiding the formation of fluid dead zones, and facilitating sufficient contact and evaporation of the liquid.

[0031] In actual manufacturing, the heating element 303 and the bent part connecting its ends can be manufactured using an integrated sintering molding process, thereby achieving structural integration, ensuring the continuity and reliability of the conductive path, and improving the consistency and durability of the product.

[0032] The principle of heating and atomization of this perforated heating element ceramic atomizing core is as follows: an external power supply supplies power to the ceramic body 1 through pin 2 and mounting through hole 5. The current is conducted to the heating mesh 3 and connected to the S-shaped heating area 302 via pin connection end 301 and solder point 305. The heating area consists of multiple strip-shaped heating elements 303, with adjacent heating elements connected by bending parts to form a continuous circuit. When current flows through, heat is generated, causing the heating elements to heat up rapidly. The heat is conducted upward through the ceramic body to the receiving cavity 4, heating the atomizing liquid inside. After being heated to the vaporization temperature, the atomizing liquid rapidly vaporizes, completing the atomization process. The heat dissipation holes 304 evenly arranged on the heating elements 303 not only improve heat exchange efficiency but also assist in uniform liquid atomization through airflow disturbance. The receiving cavity 4 adopts a vertical front-to-back and oblique left-to-right design, and an arc transition structure 401 is set between the side wall and the bottom surface to guide the liquid to concentrate in the heating area, ensuring continuous liquid supply and stable atomization.
