Technical Field
[0001] This utility model relates to the field of atomizer component technology, specifically a dual-airway integrated heating core. Background Art
[0002] Atomizers, as devices that transform liquids into a mist of tiny particles, are widely used in various fields such as medicine, beauty, and humidification. One of their core components is the heating element, whose performance directly affects the atomization effect and user experience. Traditional atomizer heating element designs often suffer from problems such as complex structure, uneven heating, high energy consumption, and susceptibility to clogging.
[0003] To address these issues, the industry has continuously innovated and improved. Among these advancements, the dual-airflow design has emerged as a significant technological development direction. The dual-airflow design aims to improve heating efficiency, enhance atomization, and reduce the risk of blockage by rationally allocating airflow channels. However, early dual-airflow designs often struggled to achieve structural integration, leading to manufacturing difficulties, high costs, and potential issues such as air leakage or heat loss during use. Summary of the Invention
[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a dual-air-channel integrated heating core, which can effectively solve the problem of low heating efficiency mentioned in the background technology.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a dual-airway integrated heating core, including two parallel cotton rods, a support frame is provided between the cotton rods, a heating mesh is provided on the outside of the support frame and the cotton rods, an oil-guiding cotton and a bracket are installed on the side of the heating mesh, the oil-guiding cotton is installed between the heating mesh and the bracket, and a bottom cover is installed at the lower end of the oil-guiding cotton and the heating mesh, and the bottom cover is fixedly connected to the bracket.
[0006] Furthermore, the bracket has a card interface and a first through hole, and the oil-guiding cotton is provided with a limiting protrusion corresponding to the shape of the card interface. The oil-guiding cotton is fixed by being inserted into the card interface through the limiting protrusion.
[0007] Furthermore, the support frame is provided with a pin fixing part, which fixes the pins of the heating mesh.
[0008] Furthermore, the bottom cover is provided with a second through hole for the cotton swab and a third through hole for the heating mesh pins.

DETAILED DESCRIPTION
[0025] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.
[0026] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. Example
[0027] like Figure 1-6 As shown, this utility model provides a dual-airway integrated heating core, including two parallel cotton rods 4, a support frame 7 between the cotton rods 4, and a heating mesh 10 on the outer side of the support frame 7 and the cotton rods 4. The two ends of the heating mesh 10 are bent and rolled around the sides of the cotton rods 4. The heating mesh 10 can control one side to work independently or both sides to work simultaneously. The heating mesh 10 is equipped with an oil-guiding cotton 8 and a bracket 3 sleeved on the side of the heating mesh 10. The oil-guiding cotton 8 is installed between the heating mesh 10 and the bracket 3. A bottom cover 12 is installed at the lower end of the oil-guiding cotton 8 and the heating mesh 10. The bottom cover 12 is fixedly connected to the bracket 3.
[0028] The cotton swab 4 guides the e-liquid evenly and continuously from the storage area to the heating area. The cotton swab 4 ensures good absorption and retention of the e-liquid, facilitating smooth flow and even distribution.
[0029] The support frame 7 is located between the two cotton swabs 4, providing a stable support structure to prevent the cotton swabs 4 from shifting or deforming during use.
[0030] The heating mesh 10 heats the e-liquid on the cotton swab 4, atomizing it into inhalable vapor. The heating mesh 10 ensures that the e-liquid is heated and atomized sufficiently and quickly.
[0031] Oil-guiding cotton 8 is installed between the heating mesh 10 and the bracket 3 to further promote the even distribution and penetration of e-liquid.
[0032] The bottom cover 12 is fixedly connected to the bracket 3, sealing the lower end of the heating element. The bottom cover 12 not only prevents the leakage of e-liquid and the entry of impurities, but also improves the overall safety.
[0033] The synergistic effect of the cotton swab 4, the wicking cotton 8, and the heating mesh 10 achieves efficient and uniform atomization of the e-liquid. This design ensures that the e-liquid can fully contact the heating mesh 10 and be rapidly heated into vapor.
[0034] The support frame 7 and the bottom cover 12 provide a stable support structure for the entire heating core, preventing deformation and damage caused by external forces or high temperatures. The design of fixing pins 11 in the support frame 7 also enhances the stability and reliability of the heating mesh 10.
[0035] See Figure 1 The bracket 3 has a card interface 5 and a first through hole 6. The oil-guiding cotton 8 is provided with a limiting protrusion 9 corresponding to the shape of the card interface 5. The oil-guiding cotton 8 is fixed by being inserted into the card interface 5 through the limiting protrusion 9.
[0036] The cooperation between the card interface 5 and the limiting protrusion 9 ensures that when the oil-guiding cotton 8 is placed on the bracket 3, the limiting protrusion 9 can accurately engage with the card interface 5, thereby achieving a stable fixation of the oil-guiding cotton 8. The oil-guiding cotton 8 is not prone to displacement or falling off during use, ensuring its stability and reliability in the heating core.
[0037] When the oil-wicking cotton 8 needs to be cleaned or replaced, the user can easily remove it from the bracket 3 without a complicated disassembly process.
[0038] See Figure 1 The support frame 7 is provided with a pin 11 fixing part, which fixes the pin 11 of the heating mesh 10.
[0039] The pin 11 is securely fixed by the pin 11 fixing part, which can tightly fix the pin 11 of the heating mesh 10 and prevent it from loosening during operation. The secure pin 11 fixing reduces the risk of short circuit caused by the loose pin 11 and improves the safety of the equipment.
[0040] See Figure 1 The bottom cover 12 is provided with a second through hole 13 for the cotton swab 4 and a third through hole 14 for the lead 11 of the heating mesh 10.
[0041] The cotton swab 4 is connected to the oil tank through the second through hole 13, ensuring smooth flow and continuous supply of e-liquid; the cotton swab 4 is fixed between the bottom cover 12 and the support frame 7 through the second through hole 13, which serves to support and position the cotton swab 4.
[0042] The third through hole 14 allows the pins 11 of the heating mesh 10 to pass through the bottom cover 12 and connect to the power supply or other control components.
[0043] See Figure 1 and Figure 2 The heating core is wrapped with outer cotton 2 and outer cover 1.
[0044] The outer cotton 2 has excellent oil absorption and conduction properties, effectively absorbing and storing e-liquid to ensure a continuous supply of e-liquid within the heating element. When the heating element is operating, the e-liquid in the outer cotton 2 is gradually guided to the heating mesh 10 area, where it rapidly atomizes into inhalable vapor upon contact with the high-temperature heating mesh 10.
[0045] The outer casing 1 effectively concentrates and shapes the two airways of the dual-airway integrated heating core. This design helps ensure that the e-liquid can flow along the predetermined path during atomization, avoiding leakage and waste. The concentration of the airways also improves the atomization efficiency of the e-liquid, making the vapor more concentrated and uniform.
[0046] See Figure 6 In another embodiment, the heating core is wrapped with a fiberglass tube 16.
[0047] The fiberglass tube 16 effectively combines two airways that might otherwise be separate into one, simplifying the structure of the heating element and allowing the e-liquid to flow more concentratedly and efficiently during atomization.
[0048] The combined airflow channels ensure that e-liquid vapor flows along a more optimized path as it passes through the heating element, reducing airflow turbulence and energy loss, thereby improving atomization efficiency and vapor uniformity.
[0049] See Figure 1 and Figure 6 Both the outer cover 1 and the fiberglass tube 16 are equipped with air collection ports 17.
[0050] The design of the air collection port 17 allows the e-liquid vapor generated from the heating element to flow out more concentratedly and efficiently. In the dual-airway design, the air collection port 17 also helps to balance the air pressure between the airways, ensuring that the airflow and speed of each airway are relatively uniform.
[0051] The air intake 17 guides the e-liquid vapor to escape smoothly, preventing it from accumulating or stagnating inside the heating element. This helps reduce vapor condensation and backflow, improving atomization efficiency and vapor purity.
