Description

Technical Field

[0001] This invention relates to the field of electronic product manufacturing, and more particularly to a heating structure and an aerosol generating device. Background Technology

[0002] With the increasing prevalence of electronic products, the demand for aerosol generators is rising. The heating structure of an aerosol generator is crucial; the aerosol-generating matrix is ​​heated by this structure to produce aerosols, which are then ingested by the user. Currently, most commercially available aerosol generators use electromagnetic induction to heat the aerosol-generating matrix. While this method reduces battery consumption, the typical structure involves winding a coil around a metal component, inserting the aerosol-generating matrix into the metal, and then heating the matrix through the metal to generate aerosols. Alternatively, electrodes can be used to create a high-frequency electric field using a high-frequency voltage to heat the metal component, which in turn heats the aerosol-generating matrix.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0033] Reference Figures 1 to 6This document illustrates an embodiment of the heating structure of the present invention. The heating structure includes a magnetic conductor 200 and a heating element 100. The magnetic conductor 200 includes a magnetic core 210, an electromagnetic part 220, and a conductive coil 221. The magnetic core 210 is connected to the electromagnetic part 220, and the conductive coil 221 is wound around the electromagnetic part 220. The magnetic core 210 is hollow, and its periphery is used to contact the aerosol generating matrix 300. The heating element 100 passes through the magnetic core 210. When the magnetic conductor 200 is energized, the conductive coil 221 generates a magnetic field. The electromagnetic field is guided through the electromagnetic part 220 to the magnetic core 210, and the heating element 100 generates heat to heat the magnetic core 210, thereby heating the aerosol generating matrix 300. Specifically, the magnetic conductor 200 can be ferrite or other magnetically conductive materials, which are not limited here. In this embodiment, the magnetic conductive element 200 is made of ferrite, which has high permeability at high frequencies. The conductive coil 221 is wound around the lower end of the electromagnetic part 220. The heating element 100 is made of metal materials such as iron-nickel alloy, permalloy, and stainless steel, which can effectively absorb and conduct heat. The heating element 100 is inserted into the magnetic core part 210. Utilizing the properties of the ferrite, the local electromagnetic field generated by the conductive coil 221 can be uniformly guided to the periphery of the magnetic core part 210, thereby uniformly heating the heating element 100 from all sides. The heating element 100 heats the magnetic core part 210 of the magnetic conductive element 200, which in turn heats the aerosol generating matrix 300 fitted on the outside of the magnetic core part 210, thus generating an aerosol. This heating structure reduces electromagnetic losses and concentrates heat, resulting in high heating efficiency of the aerosol generating device. Simultaneously, the miniaturization of the electromagnetic heating module saves space, makes it convenient for users to carry, and improves the user experience.

[0034] In one embodiment, reference is made to Figures 1 to 4As shown, the electromagnetic part 220 is provided with a first through groove 222, and the conductive coil 221 is wound around the side of the electromagnetic part 220 away from the magnetic core part 210 through the first through groove 222. Specifically, the cross-section of the first through groove 222 is rectangular, and the first through groove 222 penetrates through the front and rear sides of the electromagnetic part 220. Therefore, the electromagnetic part 220 is in the shape of a hollow cuboid, and the cross-section of the electromagnetic part 220 is in the shape of a Chinese character 'hui' (回). The conductive coil 221 is wound around the side of the electromagnetic part 220 away from the magnetic core part 210. After the conductive coil 221 is energized, the generated magnetic field is guided to the magnetic core part 210 through the 'hui' character structure of the electromagnetic part 220. This structure is simple, facilitating the installation and disassembly of the conductive coil 221 and easy to manufacture. Moreover, this structure has a guiding effect, which can evenly guide the electromagnetic field in all directions, reduce electromagnetic loss and heat concentration, thereby improving the heating efficiency of the heating structure and thus the working efficiency of the aerosol generating device. At the same time, it miniaturizes the electromagnetic heating module, saves the occupied space of the heating structure, and makes the aerosol generating device more compact.

[0035] In a specific embodiment, referring to Figures 1 to 4As shown, the electromagnetic part 220 includes a first connecting segment 223, a second connecting segment 224, a third connecting segment 225, and a fourth connecting segment 226. The first connecting segment 223, the second connecting segment 224, the third connecting segment 225, and the fourth connecting segment 226 are sequentially connected and enclosed to form the first through groove 222. One side of the first connecting segment 223 is connected to the magnetic core part 210. The third connecting segment 225 is disposed at an interval on one side of the first connecting segment 223 away from the magnetic core part 210. The conductive coil 221 is wound around the third connecting segment 225. Specifically, the first connecting segment 223 and the third connecting segment 225 are parallel to each other, the second connecting segment 224 and the fourth connecting segment 226 are parallel. The first connecting segment 223 is perpendicular to the second connecting segment 224 and the fourth connecting segment 226, and both ends of the first connecting segment 223 are respectively connected to one ends of the second connecting segment 224 and the fourth connecting segment 226. The third connecting segment 225 is perpendicular to the second connecting segment 224 and the fourth connecting segment 226, and both ends of the third connecting segment 225 are respectively connected to the other ends of the second connecting segment 224 and the fourth connecting segment 226. Therefore, the electromagnetic part 220 forms a "hui" character shape. The conductive coil 221 is wound around the third connecting segment 225. The electromagnetic generated by the conductive coil 221 starts from the third connecting segment 225 and is respectively guided to the second connecting segment 224 and the fourth connecting segment 226, and is guided to the first connecting segment 223 via the second connecting segment 224 and the fourth connecting segment 226, and finally guided to the magnetic core part 210. The structure is simple, which is convenient for the installation and disassembly of the conductive coil 221; and can make the heat more concentrated, improve the heating efficiency of the heating structure, and thus improve the working efficiency of the aerosol generating device.

[0036] In one embodiment, referring to Figure 2 and Figure 4As shown, the two ends of the third connecting segment 225 are detachably connected to the second connecting segment 224 and the fourth connecting segment 226, respectively. Specifically, the first connecting segment 223, the second connecting segment 224, and the fourth connecting segment 226 are integrally formed structures. The connection points of the first connecting segment 223, the second connecting segment 224, and the fourth connecting segment 226 are arc-shaped to prevent safety hazards caused by sharp angles at the connection points. The connection methods between the third connecting segment 225 and the second connecting segment 224 and the fourth connecting segment 226 are varied. In this embodiment, the third connecting segment 225 is engaged with the second connecting segment 224 and the fourth connecting segment 226 by setting a protrusion on the third connecting segment 225. This connection method is simple, convenient for disassembly and installation, and ensures that the conductive coil 221 is not affected by other structures, thus ensuring stable operation of the heating structure.

[0037] In a specific embodiment, refer to Figures 1 to 6 As shown, the magnetic core 210 is cylindrical in shape. A second through-slot is provided at the center of the magnetic core 210, penetrating both ends of the magnetic core 210. The first connecting section 223 has a through hole 223a. The magnetic core 210 is fixedly connected to the first connecting section 223, and the second through-slot communicates with the through hole 223a. Specifically, the magnetic core 210 is vertically fixed at the center of the first connecting section 223, and the outer diameter of the magnetic core 210 is the same as the width of the first connecting section 223. A through hole 223a is provided at the connection between the first connecting section 223 and the magnetic core 210. The diameter of the through hole 223a is the same as the inner diameter of the magnetic core 210, and the through hole 223a communicates with the second through-slot. Therefore, when the heating element 100 is inserted into the magnetic core 210, the bottom of the heating element 100 abuts against the through hole 223a, so that the electromagnetic field is directly guided to the heating element 100, and the heating element 100 is heated more evenly, with multiple heating directions and more concentrated heat, thereby improving the heating efficiency of the heating structure.

[0038] In one embodiment, reference is made to Figures 1 to 4As shown, the magnetic core 210 is provided with two channels 212 connected to the second through groove along the axial direction, and the two channels 212 are opposite to each other. The two channels 212 extend from the top of the magnetic core 210 to the bottom of the first connecting section 223. Specifically, two channels 212 are provided from the top of the magnetic core 210 to the bottom of the first connecting section 223. The channels 212 are perpendicular to the first connecting section 223 and communicate with the second through groove and the through hole 223a. The two channels 212 are opposite to each other and are arranged on the front and rear sides of the magnetic conductor 200. Therefore, when the heating element 100 is inserted into the magnetic core 210, the channels 212 increase the expansion of the magnetic core 210, which can fix the heating element 100 in the magnetic core 210. At the same time, when the heating element 100 is larger than the inner diameter of the magnetic core 210, the magnetic core 210 can be expanded through the two channels 212 to insert the heating element 100. This makes the heating structure more versatile and suitable for various heating elements 100. It also makes the magnetic core 210 less prone to damage, improves the service life of the aerosol generator, and makes the structure more stable.

[0039] In a specific embodiment, refer to Figures 1 to 10 As shown, the heating element 100 includes a heating part 110 and a guide part 120. The guide part 120 is connected to the heating part 110. The heating part 110 is installed inside the magnetic core part 210, and the guide part 120 is located outside the magnetic core part 210. Specifically, the heating element 100 has a heating part 110 and a guide part 120. When the heating element 100 is inserted into the magnetic core part 210, the heating part 110 is placed inside the magnetic core part 210, and the bottom end of the heating part 110 abuts against the first connecting section 223. The guide part 120 is located outside the magnetic core part 210. Figures 7 to 10 As shown, the heating element 110 can have various shapes, including cylindrical, semi-circular, tubular, and arc-shaped, and is not limited here. Therefore, the heating element 110 generates heat inside the magnetic core 210, transfers the heat to the magnetic core 210, and then conducts it to the aerosol generating matrix 300. The guide element 120 can guide the aerosol generating matrix 300, facilitating its insertion onto the outside of the magnetic core 210, thus improving the working efficiency of the aerosol generating device.

[0040] In one embodiment, reference is made to Figures 7 to 10As shown, the heating element 100 also includes a support portion 130, which is cylindrical in shape. Both ends of the support portion 130 are connected to the heating element 110 and the guide portion 120, respectively. The support portion 130 abuts against one end of the magnetic core portion 210. Specifically, the diameter of the support portion 130 is the same as the outer diameter of the magnetic core portion 210. When the heating element 100 is inserted into the magnetic core portion 210, the support portion 130 abuts against the top end of the magnetic core portion 210, preventing the heating element 110 from being affected by external influences and thus ensuring the operation of the heating structure. Furthermore, the support portion 130 can support and fix the heating element 100 on the outside of the magnetic core portion 210, preventing the heating element 100 from wobbling within the magnetic core portion 210 and affecting the user experience.

[0041] In a specific embodiment, refer to Figures 1 to 10 As shown, the guide portion 120 extends upward and gradually narrows to form a cone shape. Specifically, the heating element 100 is inserted into the magnetic core portion 210, the guide portion is located outside the magnetic core portion 210, and the aerosol generating matrix 300 needs to be fitted onto the outside of the magnetic core portion 210. Setting the guide portion 120 into an upwardly extending and gradually narrowing cone shape makes it easier to insert the aerosol generating matrix 300, reduces the resistance when inserting the aerosol generating matrix 300, improves the working efficiency of the aerosol generating device, and provides a better user experience.

[0042] This embodiment also provides an aerosol generating device, which includes a heating structure. The heating structure can be any heating structure provided by this invention. Since the specific structure and working principle of the heating structure have been described in detail in the previous specification, they will not be repeated here for the sake of brevity.

[0043] The aerosol generator in this embodiment, by employing the heating structure provided by the present invention, reduces the electromagnetic loss of the heating structure, concentrates the heat, and makes the heating of the aerosol generating matrix 300 more uniform, thereby improving the heating efficiency of the product. It also greatly optimizes the structural layout of the aerosol generator, resulting in a high degree of modularity and saving space in the heating structure, making the aerosol generator more compact.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention.
