Description

Technical Field

[0001] This invention relates to the field of electronic cigarette technology, and more specifically, to an electronic cigarette atomizing core. Background Technology

[0002] An electronic cigarette is an electronic product that mimics a traditional cigarette. It mainly consists of a cartridge, a vaporizer core, a circuit board, and a battery. The vaporizer core heats the atomizing medium (such as e-liquid) to atomize it into a gaseous state for output. The vaporizer core typically includes a heating element and a liquid guide. The liquid guide absorbs the atomizing medium, allowing the heating element to heat the medium on the liquid guide.

[0003] Currently, most e-cigarette atomizing cores use heating meshes (made of interwoven heating wires in a sheet shape) as their heating elements. These meshes are connected to electrodes, which supply power to the meshes, generating heat that is then transferred to the surrounding liquid guide. Existing heating meshes are typically flat sheets curled into an arc or open cylindrical shape (usually two-thirds of a full circle), then attached to the inner wall of the cylindrical liquid guide. This method is used in patents such as CN115736372A (atomizing core and related e-cigarette invention patent), CN219741856 U (a pure flat, unobstructed oil-guiding atomizing core), and CN219741856 U (utility model patent for e-cigarette). Because the cross-section of this type of heating mesh is not a full circle, it cannot achieve 360-degree heating, resulting in uneven heating, poor atomization, and low vapor production. Furthermore, this structure provides weak support and is prone to deformation.

[0004] Therefore, further improvements are needed to the atomizing core of electronic cigarettes to solve the aforementioned technical problems. Summary of the Invention

[0005] In view of this, the present invention proposes an electronic cigarette atomizing core, the specific technical solution of which is as follows: An electronic cigarette atomizing core, comprising: Central bar; The heating mesh, wrapped around the outer peripheral wall of the central rod, includes a first heating mesh sheet and a second heating mesh sheet; both the first heating mesh sheet and the second heating mesh sheet are rolled into an arc shape with a semi-circular cross-section, and the ends of the two heating mesh sheets are joined together in an integral molding manner to form a cylindrical structure with a 360° full circle cross-section. The electrode includes two first electrodes that are insulated from each other and connected in close proximity, and two second electrodes that are insulated from each other and connected in close proximity. The two first electrodes are electrically connected to the first heating mesh and the second heating mesh respectively at the first connection end of the two heating meshes; the two second electrodes are electrically connected to the first heating mesh and the second heating mesh respectively at the second connection end of the two heating meshes. Oil-wicking cotton is wrapped around the outer peripheral wall of the heating mesh.

[0007] Preferably, the upper end of the outer wall of the atomizing cylinder is provided with an opening groove for the end of the oil-guiding cotton to pass through and extend outward.

[0026] The heating mesh 2 is wrapped around the outer peripheral wall of the central rod 1, including a first heating mesh 201 and a second heating mesh 202. Both the first heating mesh 201 and the second heating mesh 202 are rolled into an arc shape with a semi-circular cross-section. At the same time, the ends of the two heating meshes are connected in pairs in an integral molding manner to form a cylindrical structure with a 360° full circle cross-section.

[0027] Electrode 3 includes two first electrodes 301 that are insulated from each other and connected in close proximity, and two second electrodes 302 that are insulated from each other and connected in close proximity. The two first electrodes 301 are electrically connected to the first heating mesh 201 and the second heating mesh 202 respectively at the first connection ends of the two heating meshes. The two second electrodes 302 are electrically connected to the first heating mesh 201 and the second heating mesh 202 respectively at the second connection ends of the two heating meshes.

[0028] The oil-wicking cotton 4 is wrapped around the outer peripheral wall of the heating mesh 2. The atomizing tube 5 is located on the outermost side of the electronic cigarette atomizing core. A part of the center rod 1 is fitted inside the atomizing tube 5. The outer layer of the oil-wicking cotton 4 abuts against the inner ring wall of the atomizing tube 5. At the same time, a through groove 501 is opened on the outer wall of the atomizing tube 5 for the oil-wicking cotton 4 to absorb oil.

[0029] In this embodiment, eight through slots 501 in two rows are equally spaced on the outer peripheral wall of the atomizing cylinder 5 to ensure that the oil-guiding cotton 4 draws oil evenly and smoothly from the oil storage core of the electronic cigarette.

[0030] In this embodiment, the bottom end of the atomizing cylinder 5 and the central rod 1 work together to seal the inner cavity of the atomizing cylinder, preventing smoke from leaking from the bottom end of the atomizing cylinder 5. A wire-passing hole is provided at the bottom end of the atomizing cylinder 5 for the electrode 3 lead wire to pass through.

[0031] Example 2: like Figures 4-8 As shown, an electronic cigarette atomizing core in this embodiment includes a center rod 1, a heating mesh 2, an electrode 3, an oil-guiding cotton 4, an atomizing cylinder 5, a fiberglass tube 6, and a fixing base 7.

[0032] The heating mesh 2 is wrapped around the outer peripheral wall of the central rod 1, including a first heating mesh 201 and a second heating mesh 202. Both the first heating mesh 201 and the second heating mesh 202 are rolled into an arc shape with a semi-circular cross-section. At the same time, the ends of the two heating meshes are connected in pairs in an integral molding manner to form a cylindrical structure with a 360° full circle cross-section.

[0033] Electrode 3 includes two first electrodes 301 that are insulated from each other and connected in close proximity, and two second electrodes 302 that are insulated from each other and connected in close proximity. The two first electrodes 301 are electrically connected to the first heating mesh 201 and the second heating mesh 202 respectively at the first connection ends of the two heating meshes; the two second electrodes 302 are electrically connected to the first heating mesh 201 and the second heating mesh 202 respectively at the second connection ends of the two heating meshes. Oil-wicking cotton 4 is wrapped around the outer peripheral wall of the heating mesh 2.

[0034] The atomizing tube 5 is located on the outermost side of the electronic cigarette atomizing core. A part of the center rod 1 is fitted inside the atomizing tube 5. The outer layer of the oil-guiding cotton 4 abuts against the inner ring wall of the atomizing tube 5. At the same time, a through groove 501 is opened on the outer wall of the atomizing tube 5 for the oil-guiding cotton 4 to absorb oil.

[0035] In this embodiment, the atomizing cylinder 5 has through grooves 501 in three of the four directions of its outer peripheral wall, and an opening groove 502 in the fourth direction. The opening groove 502 is located at the upper end of the outer wall of the atomizing cylinder 5, so that the end of the oil-guiding cotton 4 can pass through and extend outward.

[0036] In this embodiment, the through groove 501 on the atomizing cylinder 5 is used as a channel for the wicking cotton 4 to absorb oil. At the same time, this embodiment also allows the surface of the wicking cotton to extend beyond the atomizing cylinder 5, so that the wicking cotton 4 can directly contact the e-liquid reservoir of the e-cigarette. This structure ensures that the e-liquid on the reservoir can be delivered to the wicking cotton 4 more smoothly and stably.

[0037] In this embodiment, a fiberglass tube 6 is installed close to the top of the oil-guiding cotton 4 to position the upper end of the oil-guiding cotton 4; the fiberglass tube 6 is looped around the outside of the central rod and abuts against the inner wall of the atomizing cylinder 5.

[0038] In this embodiment, a fixing seat 7 is fitted and sealed between the center rod 1 and the bottom end of the atomizing cylinder 5. The fixing seat 7 seals the bottom end of the atomizing cylinder to prevent smoke from leaking from the bottom end of the atomizing cylinder. The fixing seat 7 has a wire hole 2 for the electrode lead to pass through.

[0039] In both Examples 1 and 2 above, the atomizing cylinder 5 is made of steel pipe.

[0040] Meanwhile, in Embodiments 1 and 2 above, the first electrode 301 and the second electrode 302 are respectively the positive electrode and the negative electrode, and the first electrode 301 and the second electrode 302 are respectively attached to the outer wall of the central rod 1 along the axis of the central rod (see...). Figure 9 ).

[0041] This invention designs the heating mesh as a one-piece, 360° circular cylindrical structure, which not only ensures uniform heating but also provides stronger support compared to the arc-shaped or unclosed cylindrical heating meshes in the prior art, making it more suitable for scenarios requiring flexibility and structural stability.
