[0002] This application claims priority to Chinese patent application filed on August 29, 2024, with application number 202411204537.X, entitled “Atomizing Core and Atomizing Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of atomization technology, and in particular to an atomizing core and atomizing device. Background Technology

[0004] Aerosols are colloidal dispersion systems formed by solid or liquid particles dispersed and suspended in a gaseous medium. Because aerosols can be absorbed by the human body through the respiratory system, they provide users with a novel alternative absorption method. Atomizing devices are devices that form aerosols from stored atomizable media through heating or other methods. Atomizable media include liquid, gel, paste, or solid aerosol-generating matrices. Atomizing these media delivers inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0005] In some cases, some atomizing devices are equipped with ceramic atomizing cores for heating the aerosol generation matrix. Ceramic atomizing cores are mainly divided into two types: strip-shaped atomizing cores and cylindrical atomizing cores. Among them, the airflow channel structure formed by the strip-shaped atomizing core is more complex and the aerosol transmission speed is slower. Although the airflow channel structure formed by the cylindrical atomizing core is simple and the aerosol transmission speed is faster, the proportion of large particles in the aerosol is higher and the atomization matrix consumption is lower.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] Referring to Figure 1, an embodiment of this application provides an atomizing device 100 for heating an aerosol generating matrix to generate an aerosol for user use. The aerosol generating matrix includes, but is not limited to, liquid materials used for medical, health, and beauty purposes.

[0040] The atomizing device 100 includes an atomizing component 20 and a battery component 40. The battery component 20 is located at one end of the atomizing component 20 and is electrically connected to the atomizing component 20. The atomizing component 20 is used to store the aerosol generating matrix and can heat the aerosol generating matrix under the action of electrical energy from the battery component 40 to generate aerosol for the user to use.

[0041] The atomizing assembly 20 includes a main housing 21, a nozzle 23, and an atomizing core 25. The main housing 21 has a hollow shell structure. The atomizing core 25 is housed within the main housing 21 and electrically connected to the battery assembly 40. A liquid storage chamber 21a is formed between the outer sidewall of the atomizing core 25 and the inner sidewall of the main housing 21, which is used to store the aerosol generation matrix. The nozzle 23 is located at one end of the main housing 21 and forms an outlet channel 23a for connecting the atomizing core 25 with the external atmosphere. The aerosol generation matrix stored in the liquid storage chamber 21a continuously enters the atomizing core 25, and is then heated and atomized by the atomizing core 25 to form an aerosol. The aerosol flows out through the outlet channel 23a of the nozzle 23 for use by the user. In some other embodiments, the outlet channel 23a may also be formed jointly by the nozzle 23 and the main housing 21.

[0042] As described in the background section, existing atomizer cores are mainly divided into two types: strip-shaped atomizer cores and cylindrical atomizer cores.

[0043] To facilitate contact with the conductive components below for electrical connection to the battery assembly, the heating surface of the elongated atomizing core is typically formed on the bottom surface of the core, creating a downward atomization pattern. However, the airflow channel formed by the elongated core has a complex shape, which causes larger aerosol particles to easily accumulate on the channel walls, forming condensate. This results in insufficient aerosol sweetness and a low atomization efficiency, and also negatively impacts the aroma reproduction and temperature of the aerosol, thus affecting the user experience.

[0044] The airflow channel formed by the cylindrical atomizing core has a relatively simple shape. The heating surface of the cylindrical atomizing core is located on the inner wall of the core, forming a side atomization method, resulting in a relatively fast aerosol transport speed. However, during the atomization process, because the aerosol is generated at the center of the cylindrical atomizing core, the atomization space and aerosol storage space are relatively small. This leads to two main issues: firstly, aerosol particles tend to accumulate and condense in large quantities in the airflow channel; secondly, the particle size increases while the number decreases, resulting in excessively high sweetness of the aerosol and affecting the atomization effect; and thirdly, the atomization form, which is limited by the tangential relationship between the airflow and the atomization surface, results in insufficient richness and complexity of the aerosol aroma, thus affecting the user experience.

[0045] To address the aforementioned technical issues, please refer to Figures 2 and 3. The atomizing core 25 of this application has a central axis L extending along a first direction (i.e., the Z direction in Figure 2). The atomizing core 25 is provided with an airflow channel 2521 for airflow. The airflow channel 2521 has an inlet 2521a and an outlet 2521b arranged opposite to each other in the first direction, and the cross-sectional area of ​​the outlet 2521b is larger than that of the inlet 2521a. The atomizing core 25 has a heating surface for heating the aerosol generating matrix, which is formed on the channel wall of the airflow channel 2521. Thus, external airflow flows unidirectionally within the airflow channel 2521 from the inlet 2521a to the outlet 2521b. During atomization, the external airflow flows into the airflow channel 2521 from the inlet 2521a, and then carries the aerosol generated after the aerosol generating matrix is ​​heated and atomized, flowing out from the outlet 2521b.

[0046] Because the cross-sectional area of ​​the air outlet 2521b of the airflow channel 2521 is larger than that of the air inlet 2521a, the surface area of ​​the channel wall of the airflow channel 2521 can be increased without changing the distance between the air inlet 2521a and the air outlet 2521b. This increases the heating area of ​​the heating surface formed by the channel wall, thereby effectively improving atomization efficiency. Furthermore, the airflow channel 2521 exhibits an outward diffusion trend from the air inlet 2521a to the air outlet 2521b, reducing the chance of collisions between aerosol particles. This reduces the condensation of large aerosol particles, thereby improving the mist consumption ratio, optimizing the taste of the aerosol, and enhancing the user experience.

[0047] In some embodiments, the channel wall of the airflow channel 2521 extends smoothly, and the cross-sectional area of ​​the airflow channel 2521 gradually increases from the end with the air inlet 2521a to the end with the air outlet 2521b. That is, the two sides of the longitudinal section of the airflow channel 2521 parallel to the first direction are each a smoothly extending straight line or an arc, the areas of any two cross sections of the airflow channel 2521 are not the same, and the area of ​​the cross section near the air outlet 2521b is larger than the area of ​​the cross section near the air inlet 2521a.

[0048] It is understood that the channel wall of the airflow channel 2521 can be any of the following shapes: an inverted frustum, an inverted sphere, or an inverted pyramid. It should be noted that, in this article, "inverted" refers to the lower cross-sectional area being smaller than the upper cross-sectional area, i.e., smaller at the bottom and larger at the top. Considering the convenience of the manufacturing process and the consistency of the atomizing core products, the channel wall of the airflow channel 2521 can be an inverted frustum, i.e., funnel-shaped.

[0049] In this way, without changing the distance between the air inlet 2521a and the air outlet 2521b, the heating area of ​​the heating surface formed by the channel wall is effectively increased. Moreover, the aerosol in the airflow channel 2521 gradually diffuses outward from the air inlet 2521a to the air outlet 2521b, thereby effectively reducing the chance of collision between aerosol particles. Furthermore, the airflow carrying aerosol can flow smoothly out along the smoothly extended channel wall, effectively preventing aerosol particles from colliding with the channel wall.

[0050] Furthermore, from the end with the air inlet 2521a to the end with the air outlet 2521b, at least a portion of the channel wall of the airflow channel 2521 is inclined outward and extends in a straight line away from the central axis. The inclination angle α of the channel wall of the airflow channel 2521 relative to the central axis of the airflow channel 2521 is 0° to 90°. In some embodiments, the inclination angle α is greater than 0° and less than or equal to 45°, thereby causing the cross-sectional area of ​​the airflow channel 2521 to gradually increase from the end with the air inlet 2521a to the end with the air outlet 2521b, allowing the aerosol to flow smoothly along the channel wall of the airflow channel 2521. In other embodiments, at least a portion of the channel wall of the airflow channel 2521 may also extend in a curved manner. It should be noted that "outward" in "inclined outward" mentioned above refers to the direction from the central axis of the airflow channel 2521 in the radial direction towards the edge of the atomizing core 25.

[0051] As shown in Figure 3, in one specific embodiment, the channel walls of the airflow channel 2521 extend outward at an angle relative to the central axis. The angle of inclination α of the channel walls relative to the central axis of the airflow channel 2521 is equal in all regions of the circumference. The air inlet 2521a and the air outlet 2521b are both circular. The line connecting the center point of the air inlet 2521a and the center point of the air outlet 2521b coincides with the central axis. That is, the center point of the air inlet 2521a and the center point of the air outlet 2521b are aligned in the first direction. In other words, the channel walls of the airflow channel 2521 form an inverted frustum shape.

[0052] As shown in Figure 4, in some other embodiments, the channel wall of the airflow channel 2521 extends outward at an angle relative to the central axis. However, the angle of inclination α of the channel wall relative to the central axis of the airflow channel 2521 varies in different regions of the circumference. The line connecting the center point of the air inlet 2521a and the center point of the air outlet 2521b extends at an angle relative to the central axis. That is, the center point of the air inlet 2521a and the center point of the air outlet 2521b are misaligned in the first direction. In other words, the channel wall of the airflow channel 2521 forms an inverted oblique frustum shape for the airflow channel 2521.

[0053] As a preferred embodiment, the channel wall of the airflow channel 2521 is tilted at an angle α of 5° relative to the central axis of the airflow channel 2521, thereby reducing the sweetness of the aerosol without changing the composition of the battery assembly 40, the aerosol generating matrix, and other structures, thus meeting the different taste needs of users.

[0054] It is understandable that the tilt angle α of the channel wall of the airflow channel 2521 relative to its central axis is unlimited. By changing the tilt angle α of the channel wall, it is possible to adapt to the structural design needs of different atomizing cores 25, and to directionally control the quantity and ratio of sweet and aroma particles in the aerosol. With the aerosol generation matrix composition remaining unchanged, aerosols with different concentrations of aroma and sweetness can be reproduced, effectively shortening the product development cycle and improving R&D efficiency. Moreover, the atomizing core 25 forms a quasi-upward atomization mode that combines lateral atomization and upward atomization. The airflow in the airflow channel 2521 intersects the heating surface at a certain angle. By adjusting the tilt angle of the channel wall, different intersection angles between the airflow and the heating surface can be obtained, thereby enhancing the richness of the aerosol's flavor.

[0055] Table 1-1

[0056] As shown in Table 1-1, the above embodiment adopts the atomizing core structure shown in Figure 3-5, that is, the airflow channel 2521 is an inverted frustum shape. By adjusting the inclination angle α of the channel wall of the airflow channel 2521 relative to the central axis of the airflow channel 2521, the number of large aerosol particles can be changed, the aerosol generation amount and the mist consumption ratio can be adjusted, and different tastes can be achieved to meet different user needs. Among them, the proportion of large particles refers to the proportion of aerosol particles with a diameter greater than 5μm in all aerosol particles. The inventors of this application have found that aerosol particles with a diameter greater than 5μm are more easily perceived by the taste buds, that is, aerosol particles with a diameter greater than 5μm are more likely to be deposited in the oral cavity. Therefore, the intensity of the taste, especially the intensity of the perception of sweet substances, can be adjusted by the scheme of this application without changing the composition of the aerosol generation matrix. At the same time, by increasing the aerosol generation amount and the mist consumption ratio, a richer and fuller taste is further achieved, while reducing energy consumption and meeting the requirements of environmental protection.

[0057] Please continue to refer to Figures 2 and 3. Specifically, in some embodiments, the atomizing core 25 includes a liquid guiding component 252 and a heating component 254. The liquid guiding component 252 has an airflow channel 2521. The heating component 254 is disposed inside the liquid guiding component 252 or on the channel wall of the airflow channel 2521. The heating component 254 is electrically connected to the battery assembly 40. The heating component 254 can generate heat under the action of electrical energy to heat the aerosol to generate a matrix.

[0058] Specifically, as shown in Figure 5, the liquid guide 252 is cylindrical. In some embodiments, from the end with the air inlet 2521a to the end with the air outlet 2521b, the outer wall of the liquid guide 252 extends in a straight line along a first direction, and the outer diameter of the liquid guide 252 is equal everywhere.

[0059] As shown in Figures 6 and 7, in some other embodiments, from the end with the air inlet 2521a to the end with the air outlet 2521b, the outer wall of the liquid guide 252 extends outward at an angle away from the central axis, and the cross-sectional area of ​​the outer contour of the liquid guide 252 gradually increases. Specifically, in one embodiment, as shown in Figure 6, the liquid guide 252 is a frustum shape with a smaller bottom and a larger top; in another embodiment, as shown in Figure 7, the liquid guide 252 is a quadrangular frustum shape with a smaller bottom and a larger top.

[0060] As shown in Figures 8 and 9, in some other embodiments, from the end with the air inlet 2521a to the end with the air outlet 2521b, the outer wall of the liquid guide 252 extends inward toward the central axis, and the cross-sectional area of ​​the outer contour of the liquid guide 252 gradually decreases. Specifically, in one embodiment, as shown in Figure 8, the liquid guide 252 is a frustum shape with a larger bottom and a smaller top; in another embodiment, as shown in Figure 9, the liquid guide 252 is a truncated pyramid shape with a larger bottom and a smaller top.

[0061] It is understood that the shape of the liquid guiding component 252 is not limited to this; the liquid guiding component 252 can be in the form of a cylinder, a frustum, a pyramid, or other regular or irregular shapes. Since the cross-sectional area of ​​the liquid guiding component 252 perpendicular to the first direction is positively correlated with the storage amount of aerosol generating matrix, the larger the cross-sectional area of ​​the liquid guiding component 252, the more aerosol generating matrix is ​​stored. Therefore, the shape of the liquid guiding component 252 can be designed according to factors such as the composition of the aerosol generating matrix to meet different atomization requirements.

[0062] Furthermore, the liquid guiding element 252 is formed of a porous material. In some embodiments, the porosity of the liquid guiding element 252 is 35-80%, and the average pore size of the liquid guiding element 252 is 3 micrometers-50 micrometers, thereby having good adsorption properties to store the aerosol generation matrix.

[0063] Specifically, the liquid guiding component 252 is formed of one or more materials selected from alumina, silicon oxide, silicon nitride, silicates, hydroxyapatite, and silicon carbide. The liquid guiding component 252 can be formed by injection molding, gel injection molding, dry pressing, or extrusion molding. It is understood that the specific materials and molding methods used to form the liquid guiding component 252 are not limited to these and can be set as needed to meet different requirements.

[0064] The heating element 254 is formed from at least one of a heating wire, a heating mesh, and a heating film. The heating element 254 can be formed from one or more metal alloy materials selected from iron-chromium alloy, iron-chromium-aluminum alloy, iron-chromium-nickel alloy, chromium-nickel alloy, titanium alloy, stainless steel alloy, and precious metal alloy. The heating element 254 can be attached to or embedded in the channel wall of the airflow channel 2521 by methods such as screen printing, or it can be embedded inside the liquid guiding component 252. It is understood that the material forming the heating element 254 is not limited to these, and can be selected as needed to meet different requirements.

[0065] Furthermore, the liquid guiding component 252 and the heating component 254 can be integrally formed by sintering, or the liquid guiding component 252 can be prepared first, and then the heating component 254 can be formed by screen printing, direct bonding, or other methods.

[0066] The airflow channel 2521 of the aforementioned atomizing core 25 extends linearly along the first direction, resulting in a faster aerosol transmission speed. More importantly, because the airflow channel 2521 has an outwardly expanding structure with a gradually increasing cross-sectional area, the heating area of ​​the heating surface formed by the channel wall is effectively increased, thereby improving the atomization efficiency of the atomizing core 25, reducing condensation, and improving the mist consumption ratio. Furthermore, by adjusting the tilt angle of the channel wall of the airflow channel 2521, the quantity and ratio of sweet and aroma particles in the aerosol can be easily and directionally controlled, enriching the taste of the aerosol and meeting different user needs.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
