Description

Technical Field

[0001] This utility model relates to the field of heating element technology, specifically to a ceramic atomizing core with multiple sets of composite heating wires. Background Technology

[0002] Ceramic atomizing coils have become the mainstream choice for current atomization devices due to their uniform heating and delicate flavor. They achieve atomization by heating porous ceramic that absorbs e-liquid with a heating wire. Their core performance directly determines the product's vapor production, flavor fidelity, and lifespan. Most existing ceramic atomizing coils use single or dual heating wire structures. While these can meet basic atomization needs, their heating power is limited, resulting in low atomization efficiency and failing to satisfy experienced users' demands for large vapor production. Some technologies improve efficiency by increasing the number of heating wires. For example, patent CN 205597116U discloses an atomizing coil comprising an atomization chamber shell, a heating wire mounting base disposed within the atomization chamber shell, heating wires, and an absorber. The heating wire mounting base has four chambers, each containing the heating wire and the absorber. While this atomizing coil requires multiple heating wires to operate simultaneously, increasing atomization efficiency to four times that of a single chamber, this continuous high power can lead to excessively high heating wire temperatures, causing carbon buildup and clogging of the ceramic micropores, resulting in flavor degradation or even dry burning. 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 multiple sets of composite heating wires. By cleverly setting the connection positions of independent pins and shared pins with the composite heating wire sets, multiple sets of composite heating wires can be heated simultaneously or alternately. Simultaneous heating can greatly increase the amount of vapor and maximize the high humidity and sweet taste; while alternating heating can reduce the working power of the atomizing core, improve the atomization life of the heating wires, and provide users with more experience modes.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A ceramic atomizing core with multiple sets of composite heating wires includes a core body, a pin assembly, and multiple sets of composite heating wires. The core body has an inner air passage, the inner air passage has at least one atomizing surface, and the outer periphery of the core body has an oil guiding surface. The composite heating wires are placed inside the inner air passage and are engaged with the corresponding atomizing surface.

[0006] The pin assembly includes at least two independent pins and at least one shared pin. Multiple sets of composite heating wires are arranged circumferentially along the inner air passage, and two adjacent composite heating wires are connected in parallel.

[0013] Furthermore, the second heating wire includes two second connecting portions and at least one second heating element. The two ends of the second heating element are connected to the sidewalls of the two second connecting portions. The first connecting portions and the second connecting portions correspond one-to-one. The sidewalls of the second connecting portions are connected to the sidewalls of the corresponding first connecting portions. The second heating element is located between the two first heating elements.

[0014] Furthermore, the first heating wire also includes a third heating element located between the two first heating elements. The two ends of the third heating element are respectively connected to the side walls of the two first connecting parts, and the third heating element and the second heating element are staggered vertically.

Detailed Implementation

[0029] 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.

[0030] Example 1

[0031] like Figure 1-8 As shown, a ceramic atomizing core with multiple sets of composite heating wires includes a core body 1, a pin assembly, and multiple sets of composite heating wires 4. The core body 1 has an inner air passage 11, the inner air passage 11 is provided with at least one atomizing surface 12, and the outer periphery of the core body 1 is provided with an oil guiding surface 13. The composite heating wires 4 are placed in the inner air passage 11 and are engaged with the corresponding atomizing surface 12. The pin assembly is connected to an external power supply.

[0032] The pin assembly includes at least two independent pins 2 and at least one common pin 3. Multiple sets of composite heating wire groups 4 are arranged circumferentially along the inner hole air passage 11, and adjacent composite heating wire groups 4 are arranged in parallel. The common pin 3 is located between two adjacent composite heating wire groups 4. The side of the two composite heating wire groups 4 located at the beginning and end of the end, respectively, away from the common pin 3, is connected to the corresponding independent pin 2. Alternatively, the pin assembly includes multiple independent pins 2, and at least two composite heating wire groups 4 are arranged opposite to each other. The independent pin 2 is connected to the corresponding composite heating wire group 4.

[0033] In this embodiment, the composite heating wire groups 4 arranged opposite to each other are connected to an external power supply through their respective independent pins 2, forming an independently controlled closed loop.

[0034] In this embodiment, the atomizing surface 12 and the composite heating wire group 4 are arranged in a one-to-one correspondence.

[0035] Furthermore, one end of the independent pin 2 and / or the shared pin 3 is connected to the corresponding composite heating wire group 4, and the other end of the independent pin 2 and / or the shared pin 3 extends outward along the axial direction of the inner hole air passage 11, which facilitates assembly.

[0036] In this embodiment, the ceramic atomizing core adopts a vertical structure, and the inner air passage 11 runs through the core body 1 from top to bottom, which can effectively make the airflow to the inner air passage 11 smoother, thereby improving the atomization efficiency and taste of the atomizing core.

[0037] Furthermore, the core 1 can be in the shape of a cube, a circle, or a racetrack, and the shape of the core 1 can be selected according to the space and design.

[0038] The ceramic atomizing core of this invention, with its multiple composite heating wires, cleverly incorporates independent pins 2 and shared pins 3, allowing multiple composite heating wires to be heated simultaneously or alternately. Simultaneous heating significantly increases vapor production and maximizes the high-humidity, high-sweetness flavor, while alternating heating reduces the atomizing core's operating power, extending the atomization life of the heating wires and providing users with more experience modes.

[0039] The pin assembly of this utility model has two different implementations, and one of them can be selected according to the requirements, as follows:

[0040] Example 1-1

[0041] like Figure 1-4 As shown in Embodiment 1-1, the pin assembly includes at least two independent pins 2 and at least one common pin 3. Multiple sets of composite heating wire groups 4 are arranged circumferentially along the inner air passage 11, with adjacent sets of composite heating wire groups 4 connected in parallel. The common pin 3 is located between two adjacent sets of composite heating wire groups 4. The side of the two composite heating wire groups 4 located at the beginning and end, respectively, away from the common pin 3, is connected to the corresponding independent pin 2. That is, the common pin 3 is located between two adjacent sets of composite heating wire groups 4, and the independent pins 2 are located at the beginning and end sets of composite heating wire groups 4. This scheme allows for simultaneous heating of multiple sets of composite heating wires by controlling the independent pins 2 and the common pin 3 to be energized simultaneously. Each time, by controlling one common pin 3 and its adjacent common pin 3 or independent pin 2 to be energized, while de-energizing the remaining common pins 3 and independent pins 2, the individual composite heating wire group 4 connected at both ends to the common pin 3 and another common pin 3 or independent pin 2 is energized, allowing for alternating heating of multiple sets of composite heating wires.

[0042] In a typical embodiment 1-1, the pin assembly includes two independent pins 2 and one shared pin 3. There are two composite heating wire groups 4. The shared pin 3 is located between the two composite heating wire groups 4. The two independent pins 2 are respectively connected to the ends of the two composite heating wire groups 4 furthest from the shared pin 3, forming an independent pin 2-shared pin 3-independent pin 2 layout. By controlling the independent pins 2 and the shared pin 3 to be energized together, the two sets of composite heating wires can be heated simultaneously; by controlling the shared pin 3 to be energized while the other two independent pins 2 are de-energized, the two sets of composite heating wires can be heated alternately.

[0043] Examples 1-2

[0044] like Figure 5-8 As shown in Embodiments 1-2, the pin assembly includes multiple independent pins 2, and at least two composite heating wire groups 4 are arranged opposite each other. The independent pins 2 are connected to the corresponding composite heating wire groups 4. This scheme can achieve simultaneous heating of multiple composite heating wire groups by controlling all independent pins 2 to be energized simultaneously; by controlling a single independent pin 2 to be energized while de-energizing the other independent pins 2, the single composite heating wire group 4 connected to that independent pin 2 is energized, thereby achieving alternating heating of multiple composite heating wire groups.

[0045] In typical embodiments 1-2, the pin assembly includes four independent pins 2, and the number of composite heating wire groups 4 is two, which are arranged opposite to each other. The two ends of each composite heating wire group 4 are connected to the two independent pins 2 respectively. By controlling the four independent pins 2 to be energized simultaneously, the two composite heating wire groups can be heated simultaneously; by controlling the two independent pins 2 connected to the same composite heating wire group 4 to be energized simultaneously each time, while de-energizing the other two independent pins 2, the two composite heating wire groups can be heated alternately.

[0046] Furthermore, the composite heating wire assembly 4 includes a first heating wire 41 and a second heating wire 42 disposed opposite to the first heating wire 41. Both ends of the first heating wire 41 are connected to both ends of the second heating wire 42. One end of the first heating wire 41 or the second heating wire 42 is connected to an independent pin 2 or a shared pin 3, and the other end of the first heating wire 41 or the second heating wire 42 is connected to the shared pin 3 or the independent pin 2. Specifically, when the pin assembly is implemented as in Embodiment 1-1, one end of the first heating wire 41 or the second heating wire 42 is connected to the shared pin 3, and the other end of the first heating wire 41 or the second heating wire 42 is connected to the independent pin 2 or the shared pin 3. When the pin assembly is implemented as in Embodiment 1-2, one end of the first heating wire 41 or the second heating wire 42 is connected to the independent pin 2, and the other end of the first heating wire 41 or the second heating wire 42 is connected to the independent pin 2.

[0047] Furthermore, the first heating wire 41 and the second heating wire 42 have at least one different shape, thickness, width and / or material.

[0048] This invention achieves precise control over the resistance, power density, and thermal response speed of the heating wire through differentiated combinations of shape, size (thickness / width), and material. Specifically, the material of the heating wire determines its temperature coefficient of resistance and high-temperature resistance to adapt to the stable atomization of different components. The size (thickness / width) of the heating wire directly affects resistance and heat capacity, thus regulating the atomization burst force. For example, thin wires heat up quickly, producing a burst of vapor instantly, while thick wires heat up slowly, resulting in denser and longer-lasting vapor. The shape of the heating wire affects the heat distribution of the atomizing core, adjusting the vapor concentration and uniformity. By incorporating first and second heating wires with different shapes, thicknesses, widths, and / or materials in a single composite heating wire assembly, the synergistic adjustment of various flavor attributes can be achieved, fulfilling users' ultimate pursuit of different flavors. Qualitative adjustments can be made to electronic cigarette flavor attributes such as iciness, aroma, and sweetness.

[0049] Furthermore, the first heating wire 41 is made of nickel-chromium alloy, iron-chromium-aluminum alloy, 316 stainless steel, or titanium alloy; the second heating wire 42 is made of nickel-chromium alloy, iron-chromium-aluminum alloy, 316 stainless steel, or titanium alloy. The materials of the first heating wire 41 and the second heating wire 42 can be selected according to the required heating efficiency and stability.

[0050] Furthermore, the first heating wire 41 and / or the second heating wire 42 are provided with a plurality of grippers 43 on the side near the atomizing surface 12, and the grippers 43 are embedded in the core body 1. The grippers 43 are used to improve the stability of the connection between the heating wire and the core body 1.

[0051] In this embodiment, the gripper 43 is Z-shaped, L-shaped, or T-shaped. The gripper 43 is embedded inside the core 1, so that the heating wire is in close contact with the inner surface of the ceramic, effectively preventing the heating wire from detaching from the ceramic surface and causing dry burning.

[0052] Furthermore, the first heating wire 41 includes two parallel first heating elements 411 and two parallel first connecting portions 412. Firstly, both ends of the first heating elements 411 are connected to the upper ends of the two first connecting portions 412, respectively; secondly, both ends of the first heating elements 411 are connected to the lower ends of the two first connecting portions 412, respectively. The structure is simple and easy to assemble. In this embodiment, the first connecting portion 412 is connected to a common pin 3 or an independent pin 2.

[0053] Furthermore, the second heating wire 42 includes two second connecting portions 422 and at least one second heating element 421. The two ends of the second heating element 421 are connected to the sidewalls of the two second connecting portions 422. The first connecting portion 412 corresponds one-to-one with the second connecting portion 422, and the sidewall of the second connecting portion 422 is connected to the sidewall of the corresponding first connecting portion 412. The structure is simple and easy to assemble. In this embodiment, the second connecting portion 422 is connected to a common pin 3 or an independent pin 2.

[0054] Furthermore, the second heating element 421 is located between the two first heating elements 411. That is, the first heating elements 411 and the first connecting portion 412 are staggered and connected to form a first heating wire 41 with a through hole in the middle, and the second heating element 421 is positioned facing the through hole. This arrangement avoids the first heating elements 411 and the second heating element 421 from overlapping, which could lead to excessively high local temperatures, carbon buildup, and blockage of ceramic micropores.

[0055] Furthermore, the first heating element 411 is a straight shape, a grid shape, a bow shape, or a wave shape; the second heating element 421 is a straight shape, a grid shape, a bow shape, or a wave shape; the appropriate heating element shape can be selected according to the required heating efficiency and the contact area with the atomizing surface 12.

[0056] In this embodiment, the first heating element 411 is a linear shape with a small contact area with the atomizing surface and a small size, resulting in low resistance, high local power density, and a rich flavor from the e-liquid due to the localized high temperature. The second heating element 421 is a grid shape, which increases the contact area with the atomizing surface. Its size is relatively larger than the first heating element 411, resulting in higher resistance and lower power density, allowing for continuous heating. The larger contact area between the grid shape and the atomizing surface also leads to more uniform heat distribution and finer vapor. This configuration results in the composite heating wire consisting of a set of heating wires with strong bursts and a set of heating wires with conventional bursts. The first heating element 411 and the second heating element 421 work synergistically, and the difference in their shapes and sizes creates a combination of continuous heating (grid shape) and instantaneous bursts (linear shape), allowing the flavor components to be fully released, resulting in a rich and layered aroma.

[0057] Example 2

[0058] like Figure 9-10As shown, unlike Embodiment 1, the first heating wire 41 in Embodiment 2 further includes a third heating element 413 located between the two first heating elements 411. The two ends of the third heating element 413 are respectively connected to the sidewalls of the two first connecting portions 412. The third heating element 413 and the second heating element 421 are staggered vertically. This arrangement avoids the overlap of the first heating elements 411, the second heating element 421, and the third heating element 413, which could lead to excessively high local temperatures, carbon buildup, and blockage of ceramic micropores.

[0059] Furthermore, the third heating element 413 can be a straight line, a grid, a bow, or a wave. The appropriate heating element shape can be selected according to the required heating efficiency and the contact area with the atomizing surface 12.

[0060] In this embodiment, the first heating element 411, the second heating element 421, and the third heating element 413 are arranged sequentially. The first heating element 411 is a straight shape, the second heating element 421 is a wavy shape, and the third heating element 413 is also a wavy shape. The first heating element 411 and the third heating element 413 are internal structures of the first heating wire and are made of the same material. That is, the first heating element 411 and the third heating element 413 are made of the same material but with different shapes, and the second heating element 421 and the third heating element 413 are made of the same shape but with different materials. By utilizing temperature gradients and alternating changes in shape or material, the vapor experiences different flavor variations during its flow, solving the problem of "monotonous or discontinuous flavor" in traditional atomizing coils.

[0061] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
