In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.

[0034] See Figures 1 to 5 As shown, this utility model provides an embodiment of an atomizing core, including: a heating element 1, a first liquid guiding layer 2 and a second liquid guiding layer 3; the first liquid guiding layer 2 is wrapped around the outer periphery of the heating element 1; the second liquid guiding layer 3 is wrapped around the outer periphery of the first liquid guiding layer 2; the first liquid guiding layer 2 and the second liquid guiding layer 3 are both made of liquid-absorbing material.

[0035] Specifically, this embodiment utilizes the excellent liquid absorption and conduction properties of the absorbent material. Under the capillary action of the absorbent material, the liquid can be uniformly absorbed and transported from all directions. The second liquid-conducting layer 3 first absorbs the liquid from the storage chamber 71, while the first liquid-conducting layer 2 further transports the liquid to the heating element 1. Since the second liquid-conducting layer 3 surrounds the first liquid-conducting layer 2, it achieves uniform liquid supply from 360 degrees, overcoming the limitation of traditional metal tubes that can only guide liquid from a specific direction. This also facilitates uniform atomization of the liquid by the heating element 1, resulting in a better atomization effect. Furthermore, since the second liquid-conducting layer 3 of the absorbent material replaces the metal tube in the prior art, the material purchase cost is low, and there is no need to separately set liquid-conducting holes on the material, thereby effectively reducing production costs and simplifying the manufacturing process.

[0036] See Figure 2 As shown, in a specific embodiment, the second liquid guiding layer 3 includes a first overlapping region (not shown in the figure), an encapsulation region 31 and a second overlapping region (not shown in the figure) connected in sequence; the encapsulation region 31 encapsulates the outer periphery of the first liquid guiding layer 2, and the first overlapping region and the second overlapping region are fixedly connected to form a fixing part 32.

[0037] Specifically, by designing the second liquid-conducting layer 3 as a structure comprising a first overlapping area, a wrapping area 31, and a second overlapping area connected sequentially, the wrapping area 31 completely covers the first liquid-conducting layer 2. Combined with the fixing part 32 formed by the fixed connection between the first and second overlapping areas, a stable and closed liquid-conducting channel is constructed. This design, through the mechanical support of the fixing part 32, ensures that the second liquid-conducting layer 3 maintains its shape stability during long-term use, avoiding displacement or deformation caused by liquid flow pressure or external vibration, thereby ensuring the continuity and uniformity of liquid conduction and enhancing the overall structural strength. It can effectively resist the effects of liquid flow and external vibration, extending the service life of the atomizing core. This structural design significantly improves the stability and liquid-conducting efficiency of the second liquid-conducting layer 3. At the same time, the uniform liquid distribution ensures that all parts of the heating element 1 are fully wetted, avoiding dry burning, thereby improving the consistency of atomization effect and the purity of taste.

[0038] Understandably, the size and shape of the first overlapping area, the wrapping area 31, and the second overlapping area in the second liquid-conducting layer 3 can be precisely designed according to the size of the first liquid-conducting layer 2. For example, for a first liquid-conducting layer 2 with a larger diameter, the area of ​​the wrapping area 31 can be increased accordingly, while the width and length of the first and second overlapping areas can be reasonably adjusted to ensure the firmness of the fixed connection.

[0039] In one specific embodiment, the first overlapping area and the second overlapping area are ultrasonically welded.

[0040] Specifically, ultrasonic welding technology utilizes high-frequency vibration waves transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces rub against each other, forming a fusion between molecular layers. For the first and second overlapping areas of the second liquid-conducting layer 3, ultrasonic welding can quickly and firmly connect them together. Because the heat generated during welding is concentrated in the welding area and the welding time is short, it will not significantly affect the material and performance of the second liquid-conducting layer 3. At the same time, it can ensure the connection stability of the welded part, ensuring that the second liquid-conducting layer 3 will not develop problems such as cracking during long-term use, thus ensuring the stability of the liquid-conducting layer.

[0041] In other embodiments, the first overlapping area and the second overlapping area can also be bonded together using a hot melt adhesive with good liquid resistance, high temperature resistance, and safety. Alternatively, the first overlapping area and the second overlapping area can be sewn together. Or, hot pressing technology can be used, employing a hot press to heat and press the first overlapping area and the second overlapping area together. The specific choice can be made based on production conditions, usage requirements, etc.

[0042] It is understandable that the fixing part 32 can protrude from the encapsulation area 31, or the fixing part 32 can fully or partially overlap the encapsulation area 31. These various configurations of the fixing part 32 can adapt to different atomizing core structure requirements: protruding from the encapsulation area 31 facilitates quick positioning and installation; fully or partially overlapping the encapsulation area 31 saves space and enhances structural compactness. This improves design flexibility, allowing adaptation to atomizing devices of different sizes, while ensuring fixing strength and liquid guiding stability, and optimizing production and assembly efficiency.

[0043] See Figure 4 As shown, in a specific embodiment, the heating component 1 includes a heating element 11 and pins 12 connected to the heating element 11. A first liquid guiding layer 2 is wrapped around the outside of the heating element 11, and the pins 12 partially extend out of the first liquid guiding layer 2.

[0044] Specifically, pin 12 is used to connect the heating element 11 to the external power supply component 4, enabling the heating element 11 to generate heat when powered on. The first liquid-conducting layer 2 wraps around the heating element 11, ensuring that the liquid can be evenly transferred to the surface of the heating element 11, allowing the heating element 11 to efficiently atomize the liquid. Pin 12 extends out of the first liquid-conducting layer 2, facilitating connection to the external power supply component 4 without affecting the wrapping and liquid-conducting effect of the first liquid-conducting layer 2 on the heating element 11.

[0045] This structure makes the connection between the heating element 1 and the liquid guiding layer more reasonable, facilitating installation and disassembly. The design of pin 12 extending out of the first liquid guiding layer 2 facilitates connection with the external power supply component 4, improving production assembly efficiency. At the same time, it ensures good liquid guiding and heating effects, ensuring that the liquid can be atomized in a timely and uniform manner.

[0046] See Figure 2 As shown, in one specific embodiment, the fixing part 32 is located on the opposite side of the middle position of the heating element 11.

[0047] Specifically, this positioning ensures that the second liquid-conducting layer 3 experiences symmetrical forces on both sides when it wraps around the first liquid-conducting layer 2 and the heating element 1, avoiding localized stress concentration and resulting in more uniform force distribution. Simultaneously, since the fixing part 32 is located on the opposite side of the middle position of the heating element 11, it avoids the problem of impaired liquid conduction caused by improper positioning of the fixing part 32.

[0048] This design optimizes the encapsulation effect of the second liquid-guiding layer 3, improving the overall performance of the atomizer core. The uniform liquid guidance results in more stable atomization, providing users with a superior atomization experience, while also extending the lifespan of the atomizer core and reducing the probability of malfunctions caused by poor liquid guidance.

[0049] See Figure 5 As shown, in one specific embodiment, pin 12 is provided with a bending section 121, and the outer side of the first liquid guiding layer 2 is clamped by the bending section 121.

[0050] Specifically, by providing a bent section 121 on the pin 12, the bent section 121 can form a clamping force on the outer side of the first liquid guiding layer 2, making the connection between the heating element 1 and the first liquid guiding layer 2 more secure. During the operation of the atomizing core, it may be subjected to external forces such as vibration and shaking. The clamping structure of the bent section 121 on the pin 12 can effectively prevent the first liquid guiding layer 2 from shifting or falling off, ensuring that the first liquid guiding layer 2 is stably wrapped around the outer periphery of the heating element 1, and ensuring that the liquid can be smoothly transferred to the heating element 1.

[0051] This design enhances the connection stability between the heating element 1 and the first liquid guiding layer 2, improving the reliability of the atomizing core. This structural design is simple and effective, eliminating the need for additional complex fixing devices, reducing production costs, and simultaneously improving product quality and stability, while minimizing problems such as poor atomization effects caused by unstable connections.

[0052] Understandably, when pin 12 is connected to the external power supply component 4, the bent section 121 is positioned away from the power supply component 4. This arrangement prevents the bent section 121 from interfering with the connection between pin 12 and the power supply component 4, avoiding the risk of short circuits, while also securely clamping the first liquid guiding layer 2 to ensure the normal operation of the atomizing core.

[0053] See Figure 1 , Figures 3 to 4 As shown, in a specific embodiment, a through groove 5 is formed on the inner side of the heating element 11 and the first liquid guiding layer 2, and a support column 6 is movably connected in the through groove 5.

[0054] Specifically, during the assembly of the atomizing core, the heating element 1, the first liquid guiding layer 2, and the second liquid guiding layer 3 are prone to deformation during the wrapping process. The support column 6, as an internal support structure, provides a stable support frame. During transportation, external forces such as compression and collisions may damage the atomizing core structure; the support column 6 can withstand these forces and maintain the integrity of the overall structure. When the atomizing core is installed in the atomizing device, removing the support column 6 will not obstruct the normal operation of the atomizing core, ensuring smooth liquid transfer and atomization between the liquid guiding layer and the heating element 1, and ensuring that the atomized liquid can be smoothly discharged through the channel 5.

[0055] See Figures 4 to 5 As shown, in one specific embodiment, the heating element 11 is arranged in a mesh pattern.

[0056] Specifically, by setting the heating element 11 to a regular mesh structure, a dense and uniform heating circuit is formed inside the heating element 11, thereby greatly improving the heating efficiency and atomization amount, and significantly improving the uniformity of heat distribution. This avoids the problems of dry burning and burnt taste caused by local high temperature, bringing users a pure atomized taste and significantly improving the user experience.

[0057] In one specific embodiment, the liquid absorption rate of the second liquid-conducting layer 3 ranges from 600% to 900%, and the liquid conduction rate is from 0.008 to 0.013 grams per second.

[0058] Specifically, the liquid absorption rate and liquid conduction rate are the core performance parameters of the second liquid-conducting layer 3. A liquid absorption rate of 600% to 900% ensures that it can quickly store a sufficient amount of liquid to meet the continuous atomization requirements of the heating element; a liquid conduction rate of 0.008 to 0.013 grams per second matches the thermal power of the heating element 1, which avoids dry burning due to insufficient liquid supply and prevents liquid accumulation and leakage, thus achieving a dynamic balance between supply and demand.

[0059] In one specific embodiment, the second liquid guiding layer 3 is made of non-woven fabric.

[0060] Specifically, nonwoven fabric possesses excellent liquid absorption, breathability, and flexibility. Its unique internal fiber structure forms numerous tiny pores, which can efficiently absorb and transport liquids through capillary action, meeting the requirement of uniform liquid guidance from the atomizing core. Simultaneously, good breathability helps volatile components in the liquid to evaporate more effectively, improving the taste after atomization; flexibility makes it easier to process the nonwoven fabric into a tube to wrap the first liquid guiding layer 2, allowing it to fit tightly against the first liquid guiding layer 2, ensuring the stability of liquid guidance, and preventing damage from slight external pressure.

[0061] Preferably, in this embodiment, the second liquid-guiding layer 3 is made of non-woven fabric woven from PA+PET filament material, which has excellent liquid-guiding performance and can quickly and uniformly guide liquid through capillary action. At the same time, this material is suitable for ultrasonic molding. When ultrasonically welding the first overlapping area and the second overlapping area, it can quickly fuse without affecting the material properties, ensuring the connection strength and sealing of the fixing part 32, which is conducive to achieving 360-degree uniform liquid supply to the atomizing core and improving atomization stability and taste.

[0062] It is understood that in other embodiments, the second liquid-conducting layer 3 may also be made of other non-woven fabrics or other liquid-absorbing materials, and the first liquid-conducting layer 2 may also be made of the above-mentioned non-woven fabrics or other liquid-absorbing materials.

[0063] See Figures 1 to 7 As shown, this utility model also provides an embodiment of an atomizing device, including the atomizing core as described above, as well as a liquid cup assembly 7 and a power supply assembly 4. The power supply assembly 4 is installed inside the liquid cup assembly 7, and the liquid cup assembly 7 is also provided with an airflow channel 71. The atomizing core is installed inside the airflow channel 71, and the heating component 1 is connected to the power supply assembly 4.

[0064] Specifically, in this embodiment, the atomizing core employs a double-layer liquid-absorbing material structure, where a first liquid-guiding layer 2 encloses the heating element 1, and a second liquid-guiding layer 3 encloses the first liquid-guiding layer 2. During use, the liquid in the liquid cup assembly 7 is first absorbed by the first liquid-guiding layer 2, and then evenly transferred to the heating element 1 by the second liquid-guiding layer 3. The power supply component 4 provides electrical energy to heat the heating element 1, causing it to evenly atomize the liquid. The atomized liquid is then discharged through the airflow channel 72. This double-layer liquid-guiding structure achieves 360-degree uniform liquid supply, ensuring that the heating element 1 evenly heats and atomizes the liquid, preventing impurities and ensuring the purity of the smoke, thus providing users with a more comfortable experience.

[0065] Furthermore, since the second liquid guiding layer 3 made of liquid-absorbing material is used in this application to replace the metal tube in the prior art, the material purchase cost is low, and there is no need to set liquid guiding holes separately on the material, thereby effectively reducing production costs and simplifying the manufacturing process.

[0066] 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 technical solution are within the protection scope of this utility model.
