Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electronic cigarette technology and relates to a ceramic atomizing core heating wire. Background Technology
[0002] Atomizer cores typically consist of a liquid guiding element and a heating element. Common liquid guiding elements for atomizer cores are made of non-woven fabric, fiber bundles, and porous ceramics.
[0003] Sintered porous ceramics possess a certain degree of plasticity and high strength, and are easy to install. However, porous ceramics still have some drawbacks: due to their strong adsorption properties, their aroma reproduction is not high; porous ceramics have a low oil conduction rate and are prone to dry-burning failure, resulting in a short service life; ceramic particles are prone to detachment, posing a health risk to users. Non-woven fabrics, cotton fibers, and linen fibers offer good safety and high aroma reproduction; however, due to their common resistance wire design, the coverage ratio of the atomizing core's liquid guiding element surface is small, resulting in large atomized particles and poor flavor smoothness and fullness; they also have a high oil seepage rate, making them prone to leakage, and their flavor consistency is not high.
[0004] The heating coil in the atomizer core is a crucial component of e-cigarettes. Its main function is to heat the e-liquid, atomizing it into vapor that can be inhaled. The working principle of the heating coil is based on Joule's law. When you inhale, the airflow generated passes through the microphone and activates the power supply. That is, when current passes through a conductor, heat is generated due to the conductor's resistance. This heat is used to heat the e-liquid, causing it to evaporate and form vapor. Utility Model Content
[0005] The purpose of this invention is to provide a ceramic atomizing core heating wire that uses a double-line parallel and serpentine or "bow" shaped winding method with evenly arranged grippers to evenly distribute the heat of the heating wire onto the ceramic atomizing core, thereby solving the problems of poor atomization, severe carbon buildup, and unpleasant taste.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A ceramic atomizing core heating wire includes a heating wire and grippers; the two ends of the heating wire are electrically connected to two electrodes respectively; at least two heating wires are arranged side by side at a set interval and coiled in a serpentine or "bow" shape on the ceramic atomizing core, with the two heating wires densely arranged to form a heating area; the electrodes and the heating wires in the heating area are all fixed to the ceramic atomizing core by grippers.
[0008] As a further improvement of this utility model, the set spacing is 0.04 to 1 mm.
[0009] As a further improvement of this utility model, a gripper is provided between the two parallel heating wires to further fix the two heating wires.
[0010] As a further improvement of this utility model, the two parallel heating wires each include a straight section and a turning section.
[0011] As a further improvement of this utility model, the turning segment is an arc or a right angle.
[0012] As a further improvement of this utility model, the straight segments and turning segments are alternately and evenly distributed in the heating area.
[0013] As a further improvement of this utility model, the width of the heating wire is 0.04 to 0.3 mm.
[0014] As a further improvement of this utility model, the heating wire is made of iron-chromium-aluminum, nickel-chromium, or 316L stainless steel resistance wire.
[0015] As a further improvement of this utility model, the gripper is T-shaped or "7"-shaped.
[0016] As a further improvement of this utility model, the two or more parallel heating wires form a heating group, and several groups of heating pairs are arranged alternately or layered on the ceramic atomizing core.
[0017] Compared with the prior art, the present invention has the following advantages:
[0018] This invention creates a uniform heating area by arranging at least two heating wires in a serpentine or "bow" shape, with a set spacing, on the ceramic atomizing core. This ensures uniform heating, improves atomization efficiency and quality, enhances the smoothness and fullness of the flavor, and effectively avoids localized heat accumulation, reducing incomplete combustion and carbon buildup. The coiled heating wires are secured by grippers, stabilizing their position and reducing the risk of displacement or falling off the atomizing core, thus maintaining uniform heating.
[0019] Furthermore, the spacing between the heating wires is set to 0.04 to 1 mm. This range is designed to ensure the density of the heating area, preventing overheating or underheating, while also taking into account the workability and durability of the materials in actual production.
[0020] Furthermore, grippers are provided between the two parallel reciprocating heating wires to further secure the two heating wires. This ensures the stability and firmness of the heating wires on the ceramic atomizing core, preventing the heating wires from shifting or falling off during use.
[0021] Furthermore, the turning section is designed as an arc or a right angle. This design is conducive to improving the layout of the heating wire, increasing space utilization, and also to fixing the heating wire. The arc or right angle shape is also conducive to standardization and industrialization.
[0022] Furthermore, by alternating and evenly distributing straight and turning segments in the heating area, it is possible to ensure uniform heat distribution throughout the entire heating area, thereby improving the atomization effect; and to ensure uniform heat dissipation and distribution along the entire heating wire.
[0023] Furthermore, the width of the heating wire is designed to be 0.04–0.3 mm. This design can reduce the volume of the heating wire and improve heating efficiency while ensuring that the heating wire has sufficient strength.
[0024] Furthermore, iron-chromium-aluminum, nickel-chromium, and 316L stainless steel are selected as the materials for the heating wire. These materials all have good high-temperature resistance and oxidation resistance, which can ensure the stability and lifespan of the heating wire in high-temperature working environments.
[0025] Furthermore, by arranging or stacking several heating groups formed by two or more parallel reciprocating heating wires in an alternating manner, the entire ceramic atomizing core can be covered, achieving comprehensive heating and improving atomization efficiency.
[0026] Furthermore, the T-shaped or "7"-shaped gripper design will help to better secure the heating wire and ensure the reliability of the equipment. Attached Figure Description

[0036] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0037] It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.
[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0039] This invention proposes a ceramic atomizing core heating wire, in which at least two heating wires are coiled side by side at a set interval in a serpentine or "bow" shape on the ceramic atomizing core. This forms a uniform heating area, ensuring uniform heating, improving atomization efficiency and quality, enhancing the smoothness and fullness of the flavor, and effectively preventing localized heat accumulation and reducing incomplete combustion that produces carbon deposits. The coiled heating wires are fixed by grippers, stabilizing their position and reducing the risk of displacement or falling off the atomizing core, thereby maintaining uniform heating.
[0040] Example 1
[0041] Figure 1The ceramic atomizing core heating wire proposed in Example 1 includes two heating wires 1 and grippers 2. The two ends of each heating wire 1 are electrically connected to two electrodes 3. At least two heating wires 1 are arranged side-by-side at a predetermined interval, coiled in a serpentine or "bow" shape on the ceramic atomizing core, forming a heating area. The predetermined interval between the two heating wires is 0.04–1 mm. The two heating wires do not contact each other, are not connected, run parallel and independent, and do not interfere with each other. Their atomization surface is uniform, the surface of the heating wires 1 is not prone to carbon buildup, and adjustment is convenient. The burst is adjusted by adjusting the distance between the two wires and the wire diameter of the heating wires 1. The electrodes and the heating wires 1 in the heating area are both fixed to the ceramic atomizing core by grippers 2; the grippers 2 are correspondingly located on the inner or outer sides of the electrodes and heating wires 1.
[0042] The two parallel, serpentine or "bow"-shaped coiled heating wires 1 include seven straight segments and six turning segments; the turning segments are right-angled.
[0043] The straight segments and turning segments are evenly distributed alternately in the heating area.
[0044] Variations in the arrangement of the two parallel, serpentine or "bow"-shaped coiled heating wires 1 are as follows: Figure 2-4 As shown. The parallel direction of the heating wire 1 can be along the shortest line between the two end electrodes 3, or perpendicular to the shortest line between the two end electrodes 3; the number of straight segments and turning segments generated by the coiling of the heating wire 1 is different.
[0045] The number of heating wires 1 can also be three or more, arranged in parallel on the ceramic atomizing core in a serpentine or "bow" shape, with three or more heating wires 1 densely arranged to form a heating area.
[0046] The width of the heating wire 1 is 0.04 to 0.3 mm.
[0047] The heating wire 1 is made of iron-chromium-aluminum.
[0048] The gripper 2 is T-shaped or "7"-shaped.
[0049] Example 2
[0050] like Figure 5 As shown, compared to Example 1, the turning section of the ceramic atomizing core heating wire in Example 2 is an arc shape. The choice between an arc or a square turning section can be based on process or aesthetic considerations.
[0051] Variations in the arrangement of the two parallel, serpentine or "bow"-shaped coiled heating wires 1 are as follows: Figure 6-8 As shown. The parallel direction of the heating wire 1 can be along the shortest line between the two end electrodes 3, or perpendicular to the shortest line between the two end electrodes 3; the number of straight segments and turning segments generated by the coiling of the heating wire 1 is different.
[0052] The number of heating wires 1 can also be three or more, arranged in parallel on the ceramic atomizing core in a serpentine or "bow" shape, with three or more heating wires 1 densely arranged to form a heating area.
[0053] In addition, compared with Example 1, in Example 2, a bridging gripper is provided between the two parallel serpentine or "bow"-shaped coiled heating wires 1 of the ceramic atomizing core heating wire to further fix the two heating wires 1. The bridging gripper 2 is provided at the turning section.
[0054] Both the gripper and the resistance wire are embedded in grooves on the surface of the atomizing core. Because the gripper extends or forms a mesh structure around the resistance wire, it further increases the contact area with the groove and the bonding force within the groove. Therefore, the gripper design enhances the connection strength and prevents the resistance wire from detaching from the atomizing core groove. The gripper can be made of the same material as the resistance wire or other metal materials. Because the gripper does not form a circuit, or the potential difference between the two sides of the gripper is zero, the gripper only conducts heat but not electricity.
[0055] In addition, compared with Example 1, the heating wire 1 in Example 2 is made of nickel-chromium or 316L stainless steel.
[0056] In addition, the two or more parallel heating wires form a heating group, and several heating pairs are arranged in an alternating or overlapping manner on the ceramic atomizing core.
[0057] To verify the effect of double-wire serpentine or "bow" shaped coiling, a horizontal comparison was made between double-wire and single-wire arrangements. The experimental conditions and results are as follows. Single-wire arrangement is a common practice currently.
[0058] The experimental circuit design, such as Figure 1 As shown, two resistance wires, coiled in a serpentine or "bow" shape, are connected in parallel to two end electrodes. The distance between the two resistance wires is 0.04–1 mm, and the experimental voltage is 2.8 V. The resistance of a single resistance wire is 1 Ω, the diameter of a single wire is 0.7 mm, and the combined heating power of the two wires is 7.84 W. Using a 0.7 mm wire diameter is beneficial for amplifying the heating effect and facilitating observation. A single resistance wire, coiled in a serpentine or "bow" shape, is connected in parallel to two end electrodes. The experimental voltage is 2.8 V, the resistance of a single resistance wire is 1 Ω, the diameter of a single wire is 1.4 mm, and the combined heating power of a single wire is 7.84 W, the same as the heating power of the two coiled resistance wires.
[0059] Both dual-wire and single-wire coiled models utilize a cartridge-based electronic cigarette design. The serpentine or "bow"-shaped coiled resistance wires are fixed to a square ceramic core, with core dimensions of 9*3.6*3mm. An automatic inhaler is placed 1cm to the side of the heating zone formed by the resistance wires. The table below shows the results displayed by the automatic inhaler:
[0060]
[0061] Experimental results showed that the TPM value of the single-filament coil was 0.8 mg lower than that of the double-filament coil; a higher TPM value indicates a larger vapor production and better atomization effect. Carbon deposits appeared on 50% of the surface area of the single-filament coiled heating wire, while no carbon deposits were generated in the double-filament coiled wire.
[0062] Therefore, compared with the single-wire serpentine or "bow"-shaped coiling setup with the same heating power, the double-wire serpentine or "bow"-shaped coiling setup can significantly improve the uniformity of heating and atomization effect, and effectively control the generation of carbon deposits.
