[0002] Nebulizers are popular among users because they can provide a variety of flavors of aerosol. However, existing nebulizers usually have a straight-through airflow, which makes it difficult for the aerosol generated during the nebulization process to fully mix with the air, thus reducing the user experience. Utility Model Content

[0004] In some embodiments, a heating element is provided, including a support, a heating part, and a flow guide, wherein the support has an atomizing channel; the heating part is disposed in the atomizing channel; the flow guide is configured as a spiral structure extending axially along the atomizing channel, and the flow guide and the heating part are arranged axially along the atomizing channel.
[0005] In some embodiments, the heating element is located downstream of the flow guide.
[0006] In some embodiments, the heating element is located upstream of the flow guide.
[0007] In some embodiments, the flow guide includes a first spiral structure and a second spiral structure. The first spiral structure, the heating element, and the second spiral structure are arranged sequentially in the atomization channel along the airflow direction. The spiral directions of the first spiral structure and the second spiral structure are the same.
[0008] In some embodiments, the first cross-section of the spiral structure in the guide portion is rectangular, semi-circular, or trapezoidal, and the first cross-section coincides with the spiral centerline of the guide portion.

[0032] Please see Figures 1 to 3 , Figure 1 These are schematic diagrams of the heating element in some embodiments of this application. Figure 2 yes Figure 1 An explosion diagram of the heating element in the embodiment. Figure 3 yes Figure 1 Top view of the heating element in the embodiment.
[0033] This application provides a heating element 10, including a bracket 11, a heating part 12 and a flow guiding part 13. The bracket 11 is made of a high-temperature resistant and corrosion-resistant hard material, and the bracket 11 is provided with an atomization channel 112. For example, the bracket 11 is a fiberglass tube or a steel tube.
[0034] The heating element 12 is located within the atomization channel 112 and is used to heat the atomization matrix to form an aerosol. The heating element 12 can be made of materials such as resistance wire, electric heating film, or ceramic heating element, and has the advantages of fast heating speed and uniform heating.
[0035] The flow guide 13 is configured as a spiral structure extending axially along the atomization channel 112, and the flow guide 13 and the heating element 12 are arranged axially along the atomization channel 112. The flow guide 13 is made of a high-temperature resistant and corrosion-resistant material. For example, the flow guide 13 can be made of stainless steel, titanium alloy, ceramic, or glass, which can maintain the stability and integrity of the structure under high temperature and corrosive environments. In addition, these materials also have good biocompatibility and chemical inertness, and will not react chemically with the atomization matrix, thereby ensuring the safety and purity of the atomized product.
[0036] In this embodiment, the bracket 11 serves as a basic support component, and its internal atomization channel 112 defines the spatial path through which the aerosol flows. A continuous flow path is formed by axially arranging the heating element 12 and the spiral-structured guide element 13 within the atomization channel 112. The spiral-structured guide element 13 guides the flowing gas to form a spiral airflow, disturbing the aerosol and air and enhancing their mixing effect. Simultaneously, the condensate formed during the aerosol condensation process is blocked by the guide element 13, making it difficult for the condensate to flow. When the heating element 12 heats the aerosol, this condensate can be re-atomized, thereby reducing leakage.
[0037] Please see Figure 4 , Figure 4 yes Figure 1 A cross-sectional view of the heating element in the embodiment. In some embodiments, the heating element 12 is located upstream of the flow guide 13. Downstream refers to the flow direction downstream of the aerosol generated by the heating element 10 under normal operating conditions, and the opposite direction is upstream. Figure 4 As shown, the heating element 12 is positioned below the guide element 13. The airflow passes through the heating element 12 and the guide element 13 sequentially from bottom to top along the atomization channel 112 before being output. During operation, the heating element 12 generates aerosols by heating the atomization matrix. These aerosols are guided to the guide element 13 by the rising airflow. The spiral structure of the guide element 13 effectively agitates the airflow and aerosols, ensuring thorough mixing of the aerosols. Furthermore, the design of the guide element 13 extends the residence time of the aerosols within the atomization channel 112, thereby improving the uniformity of the atomization process.
[0038] Please see Figure 5 , Figure 5 This is a cross-sectional view of the heating element in another embodiment. In some embodiments, the heating element 12 is located downstream of the guide element 13, and the airflow passes through the guide element 13 and the heating element 12 sequentially from bottom to top along the atomization channel 112 before being output. During operation, the heating element 12 generates aerosol by heating the atomization matrix. The spiral structure of the guide element 13 effectively disturbs the airflow, causing it to spiral upward and reducing dead zones in the gas flow. The spirally rising airflow drives the aerosol to mix thoroughly, thereby better restoring the original flavor of the aerosol.
[0039] Please see Figure 6 , Figure 6 This is a cross-sectional view of the heating element in another embodiment. In some embodiments, the flow guide 13 includes a first spiral structure 131 and a second spiral structure 132. The first spiral structure 131, the heating element 12, and the second spiral structure 132 are arranged sequentially along the airflow direction within the atomization channel 112, and the spiral directions of the first spiral structure 131 and the second spiral structure 132 are the same. Figure 6As shown, the airflow passes sequentially through the first spiral structure 131, the heating element 12, and the second spiral structure 132 along the atomization channel 112 before being output. During operation, the heating element 12 generates aerosol by heating the atomization matrix. The first spiral structure 131 effectively agitates the airflow, causing it to spiral upwards and significantly reducing dead zones in the gas flow. Subsequently, the aerosol is guided by the rising airflow to the second spiral structure 132, which further agitates the airflow to ensure thorough mixing of the aerosol. Furthermore, the design of the second spiral structure 132 extends the residence time of the aerosol within the atomization channel 112, thereby improving the uniformity of the atomization process. To ensure the stability of the airflow output, the spiral directions of the first spiral structure 131 and the second spiral structure 132 are consistent, preventing convection between the two spiral structures and thus avoiding insufficient air supply or leakage.
[0040] Please see Figure 4 In some embodiments, the first cross section of the spiral structure in the guide section 13 is rectangular, semi-circular or trapezoidal, and the first cross section is a plane passing through the spiral center line of the guide section 13, that is, the first cross section coincides with the spiral center line of the guide section 13.
[0041] In some embodiments, the inner diameter of the guide portion 13 ranges from 1.5 mm to 5 mm. For example... Figure 4 As shown, the spiral structure of the guide section 13 protrudes radially inward from the sidewall of the atomizing channel 112. The inner diameter of the guide section 13 refers to the distance between the outer edge of the spiral structure and the opposite sidewall of the atomizing channel 112, i.e. Figure 4 The distance d1 in the middle. The inner diameter of the guide section 13 can be 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm or 5mm, and is not specifically limited here. It is understood that when the inner diameter of the guide section 13 is too small, the aerosol is easily blocked, resulting in insufficient air supply during the user's inhalation process in the atomization process. When the inner diameter of the guide section 13 is too large, it may lead to insufficient turbulence. In this embodiment, the inner diameter of the guide section 13 is limited to a suitable range, so that the guide section 13 can turbulent the airflow while ensuring air supply efficiency during the atomization process.
[0042] In some embodiments, the distance between the spiral structure of the guide section 13 and the heating section 12 along the axial direction of the atomization channel 112 ranges from 0 mm to 20 mm, specifically 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 10 mm, 15 mm, or 20 mm, without specific limitation. It is understood that when the distance between the guide section 13 and the heating section 12 is closer, the temperature near the guide section 13 is higher, which enhances the activity of gas molecules, resulting in a more ideal mixing effect for the aerosol. However, when the distance between the guide section 13 and the heating section 12 is too large, the heat generated by the heating section 12 cannot be effectively transferred to the aerosol near the guide section 13, leading to a weakened mixing effect of the guide section 13 on the aerosol. Furthermore, this situation requires a longer length for the atomization channel 112, thereby increasing the structural volume. In this embodiment, the distance between the spiral structure of the guide section 13 and the heating section 12 in the axial direction of the atomization channel 112 is controlled within a reasonable range to ensure efficient heat transfer and uniform aerosol atomization, so that users can obtain a more stable and delicate aerosol during inhalation.
[0043] In some embodiments, the length of the guide portion 13 ranges from 5 mm to 25 mm. Specifically, the length of the guide portion 13 can be 5 mm, 10 mm, 15 mm, 20 mm or 25 mm, and is not specifically limited here.
[0044] In some embodiments, the helical angle of the flow guide 13 is 15° to 75°. Specifically, the helical angle of the flow guide 13 can be 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70° or 75°, and is not specifically limited here.
[0045] Please see Figure 2 In some embodiments, a liquid guiding section 14 is also included. The liquid guiding section 14 is made of a porous material, which has good liquid absorption and guiding properties. Specifically, the liquid guiding section 14 can be a cotton wick or porous ceramic, ensuring that the heating element 12 stably and continuously produces aerosol. The cotton wick material is soft and has good liquid absorption, ensuring uniform distribution of the atomizing matrix and resulting in a finer atomization effect. The porous ceramic material has high high-temperature resistance and chemical stability, able to withstand the high-temperature environment of the heating element 12 during operation, while ensuring effective atomization of the atomizing matrix. The provision of the liquid guiding section 14 further improves the performance and atomization effect of the heating element 10 in this embodiment.
[0046] The support 11 is provided with a liquid inlet 111, and the liquid guiding part 14 is located inside the support 11 and is in fluid communication with the outside of the support 11 through the liquid inlet 111. The liquid guiding part 14 has a hollow tubular structure, and the heating part 12 is located on the inner wall of the liquid guiding part 14.
[0047] In the embodiment where the flow guide 13 is located at one end of the heating element 12, the flow guide 13 and the bracket 11 can be integrally formed, which reduces the assembly process and ensures the integrity of the structure. In addition, this integral structure can simplify the manufacturing process and reduce production costs.
[0048] In the embodiment where the heating element 12 is positioned between the first spiral structure 131 and the second spiral structure 132 of the flow guide 13, the first spiral structure 131, the second spiral structure 132, and the support 11 can be separately installed and fixedly connected by means of bonding, snap-fit, or other methods. This facilitates the installation of the heating element 12 between the first spiral structure 131 and the second spiral structure 132.
[0049] In some embodiments, at least two liquid inlets 111 are provided along the circumference of the support 11. The liquid guiding part 14 can adsorb atomizing matrix of different flavors to the heating part 12 through multiple liquid inlets 111. After the atomizing matrix is heated by the heating part 12 to form an aerosol, the spiral structure of the guide part 13 is used to fully mix the aerosols of different flavors.
[0050] In some embodiments, the heating element 12 is spiral-shaped, adapted to the spiral airflow field guided by the flow guide 13, further promoting uniform heating and thorough mixing of the aerosol during the flow process. This design results in a more delicate taste and a superior user experience for the final aerosol output.
[0051] In some embodiments, the heating element 12 is designed in a sheet shape, which can heat a large area of atomized matrix, thereby rapidly generating a large amount of aerosol.
[0052] In some embodiments, the heating element 12 is in the form of a mesh or a grid. This increases the contact area with the atomizing matrix, improving heating efficiency. The mesh or grid design not only increases the contact area between the heating element 12 and the atomizing matrix, improving heating efficiency, but also ensures that the aerosol is heated more evenly during passage, avoiding localized overheating or underheating. This optimizes the aerosol generation process, resulting in a finer aerosol with a richer flavor profile, providing users with a superior experience.
[0053] Please see Figure 4 In some embodiments, the inner diameter of the flow guide 13 is smaller than the inner diameter of the liquid guide 14. Figure 4 The distance d2 is the inner diameter of the liquid guiding section 14, so d1 < d2. This design allows the flow guiding section 13 to effectively compress and accelerate the passing airflow, further enhancing the mixing effect of aerosols in the spiral airflow.
[0054] Please see Figure 7 , Figure 7This is a schematic diagram of the structure of an atomizing device in some embodiments of this application. In some embodiments, an atomizing device is provided, which includes the heating element 10 in any of the above embodiments. The atomizing device can be a cartridge or a complete device.
[0055] The atomizing device also includes a housing 20, within which a liquid storage chamber 21 is provided, and a heating element 10 is disposed within the liquid storage chamber 21. The liquid storage chambers 21 can be separated by partitions to form multiple independent chambers, such as two, three, or four. Different flavored atomizing bases are stored in the multiple liquid storage chambers 21. Users can freely choose different flavored atomizing bases to mix according to their personal preferences, or experience different flavors at different times, greatly enriching the user experience.
[0056] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
