[0017] The utility model provides a kind of atomization structure 100.
[0018] Please see Figure 1 In one embodiment of the present invention, the atomizing structure 100 includes a body 1, a filter element 2, and a heating component 3; a filter chamber 1a and a heating channel 1b communicating with the filter chamber 1a are formed in the body 1; the filter element 2 is located within the filter chamber 1a; the heating component 3 is connected to the body 1 and is disposed in the heating channel 1b; wherein, the heating component 3 is used to heat the contents in the heating channel 1b to generate smoke, and the filter element 2 is used to filter the smoke generated in the heating channel 1b.
[0019] In this embodiment, the atomizing structure 100 includes a body 1, a filter element 2, and a heating assembly 3. The body 1 has two main spaces: a filter chamber 1a and a heating channel 1b, which are interconnected. During actual assembly, the filter element 2 is precisely placed and confined within the filter chamber 1a, while the heating assembly 3 is connected to the body 1 and installed on the outer or inner wall of the heating channel 1b. The filter element 2 can be made of porous materials, such as activated carbon, fiber materials, polypropylene filter element 2, or degreased cotton thread, to improve filtration efficiency. The design of the filter element 2 allows for multiple uses, eliminating the need to replace it every time the cartridge 4 is replaced. In use, the user places the substance to be heated (such as tobacco or e-liquid) into the heating channel 1b. The heating assembly 3 heats the substance in the heating channel 1b using heating elements such as resistance wires and ceramic heating plates. As the heating process proceeds, the substance produces smoke, which enters the filter chamber 1a through the interconnected channel and is filtered by the filter element 2. The smoke, filtered by filter element 2, is now purer and is then inhaled by the user through the smoke outlet 12a of the main body 1. This structural design allows for a seamless integration of the heating and filtration processes, achieving efficient smoke generation and purification.
[0020] This atomizing structure 100 separates the filter element 2 from the heating channel 1b, allowing for independent replacement of the filter element 2 without discarding it every time the cartridge 4 is replaced, thus significantly reducing operating costs. The filter element 2 is specifically designed to filter the smoke generated within the heating channel 1b, effectively removing impurities and harmful substances and improving the purity and safety of the smoke produced by the atomizing structure 100. The interconnected design of the filter chamber 1a and heating channel 1b within the main body 1 allows smoke to quickly enter the filter chamber 1a after generation, reducing smoke loss during transmission and improving overall atomization efficiency. The independent design of the filter element 2 and heating component 3 allows users to replace either the filter element 2 or the heating component 3 as needed, without replacing the entire cartridge 4 assembly, simplifying maintenance and enhancing the user experience. This atomizing structure 100 is suitable for various heat-not-burn electronic cigarettes or atomizing devices, offering broad applicability and meeting the needs of different users.
[0021] In one embodiment of this utility model, please refer to Figure 1 andFigure 2 The body 1 has a holding part 11 and a rotating part 12, the rotating part 12 is rotationally connected with the holding part 11, the filter cavity 1a is located in the rotating part 12, and the heating channel 1b is located in the holding part 11.
[0022] In an embodiment, the body 1 is designed as a split structure including the holding part 11 and the rotating part 12. The holding part 11 is a part held by a user, and the holding part 11 is internally provided with the heating channel 1b, and the heating assembly 3 is installed in or around the heating channel 1b, for heating substances in the heating channel 1b and generating smoke. The rotating part 12 is rotationally connected with the holding part 11 through hole shaft cooperation or hinge connection and the like, and the rotating part 12 is internally provided with the filter cavity 1a, and the filter core 2 is fixed in the filter cavity 1a, for filtering smoke generated by the heating channel 1b. Through the relative rotation of the rotating part 12 and the holding part 11, the user can replace the cartridge 4 or the tobacco tar and the like in the heating channel 1b according to needs, and at the same time, the filter core 2 can be conveniently cleaned and replaced, so as to optimize the smoke filtering effect. The filter cavity 1a and the heating channel 1b are respectively arranged in the rotating part 12 and the holding part 11, so that the product is more compact and reasonable in structure, and function partition is realized, which is convenient for user operation and maintenance. Since the rotating part 12 and the holding part 11 can be relatively rotated, the user can easily disassemble the rotating part 12, clean or replace the filter core 2 or the heating channel 1b, prolong the service life of the product, and reduce the use cost.
[0023] In an embodiment of the utility model, please refer to Figure 2 The rotating part 12 is provided with a smoke outlet 12a, the smoke outlet 12a is located on a side of the filter core 2 away from the heating channel 1b, and the smoke outlet 12a is connected with the filter cavity 1a and the outside.
[0024] In the embodiment, the rotating part 12 is provided with a smoke outlet 12a located on the side of the filter element 2 away from the heating channel 1b and connected with the outside through the filter cavity 1a. The rotating part 12 is generally made of PEEK, PCTG or other high-temperature-resistant metal materials. In use, the substance (e.g. smoke cartridge 4 or smoke oil) in the heating channel 1b is heated by the heating assembly 3 to generate smoke, which enters the filter cavity 1a through the heating channel 1b, is filtered by the filter element 2, and is then discharged through the smoke outlet 12a for the user to inhale. This design allows the smoke to be directly discharged from the smoke outlet 12a of the rotating part 12 after filtration, avoiding secondary pollution of the smoke during transmission. The smoke outlet 12a is located on the side of the filter element 2 away from the heating channel 1b, ensuring that the smoke is directly discharged after filtration by the filter element 2, reducing the residence time of the smoke in the device, and avoiding the backflow and secondary pollution of the condensate. The design of the smoke outlet 12a in combination with the rotating part 12 makes the entire atomization structure 100 more compact, and facilitates the cleaning and replacement of the filter element 2 and the smoke outlet 12a by the user. Since the smoke outlet 12a is located on the side of the filter element 2 away from the heating channel 1b, the smoke can more fully contact the surface of the filter element 2 when passing through the filter element 2, thereby improving the filtration efficiency and further improving the purity of the smoke.

[0026] In an embodiment, the body 1 further comprises a first connecting part 13 and a second connecting part 14. The first connecting part 13 is connected with the rotating part 12, the second connecting part 14 is connected with the holding part 11, and the first connecting part 13 can be connected with the second connecting part 14. This design realizes flexible assembly and disassembly of the rotating part 12 and the holding part 11 through split connection. In actual application, the first connecting part 13 and the second connecting part 14 can be connected through various connection modes, such as buckle connection or magnetic connection, etc. This design not only facilitates users to quickly disassemble and assemble the rotating part 12 and the holding part 11 according to needs, but also enables damaged parts to be replaced individually when needed, thereby reducing maintenance cost. The connection between the first connecting part 13 and the rotating part 12, and the connection between the second connecting part 14 and the holding part 11 can be realized through buckle or adhesive connection, etc. Through the connection relationship of the first connecting part 13 and the second connecting part 14, the user can easily separate the rotating part 12 from the holding part 11, facilitating cleaning or replacement of components such as the filter element 2 and the heating assembly 3. The split connection mode simplifies the assembly steps in the production process, while reducing the risk of whole machine scrapping due to component damage, thereby reducing production cost. Users can quickly replace the filter element 2 or adjust the structure of the equipment according to personal preferences or use habits, thereby improving the use convenience and user satisfaction of the product.
[0027] In an embodiment of the utility model, please refer to Figure 2 The first connecting part 13 and the second connecting part 14 are both magnetic parts, and / or one of the first connecting part 13 and the second connecting part 14 is a magnetic part, and the other of the first connecting part 13 and the second connecting part 14 is an iron block.
[0028] In this embodiment, the first connecting part 13 and the second connecting part 14 are both magnetic parts, or one of them is a magnetic part and the other is an iron block. This design realizes quick connection and disassembly of the rotating part 12 and the holding part 11 through magnetic adsorption. Specifically, the first connecting part 13 and the second connecting part 14 can be connected through the cooperation of a magnetic part and an iron block. For example, the first connecting part 13 can be a magnetic part (such as a magnet), and the second connecting part 14 is an iron block, which are tightly connected through magnetic adsorption. This connection mode not only is simple to operate, but also ensures the stability of the connection. The cooperation of the magnetic part and the iron block makes the connection and disassembly of the rotating part 12 and the holding part 11 more convenient, which can be completed by the user without complex tools or operations. Magnetic adsorption can provide sufficient connection strength to ensure that the equipment will not loosen during use, while avoiding the wear or loosening problems that may occur in traditional threaded connection. The connection mode of the magnetic part and the iron block reduces the complexity of mechanical processing and assembly, thereby reducing production cost.
[0029] In an embodiment of the utility model, please refer to Figure 2In the axial extension direction of the heating channel 1b, the cross-sectional area of the filter core 2 close to one end of the heating channel 1b is larger than the cross-sectional area of the heating channel 1b.
[0030] In an embodiment, the cross-sectional area of the filter core 2 close to one end of the heating channel 1b is larger than the cross-sectional area of the heating channel 1b. This design allows the filter core 2 to form a relatively larger cross-section close to the heating channel 1b, thereby better receiving and filtering the smoke generated from the heating channel 1b in the axial extension direction of the heating channel 1b. The structure of the filter core 2 can be designed to have a larger cross-sectional area close to one end of the heating channel 1b, which can be achieved by adjusting the shape or material of the filter core 2. For example, the filter core 2 can adopt a conical or stepped structure to form a larger cross-section close to one end of the heating channel 1b, thereby increasing the contact area with the smoke. The larger cross-sectional area allows the filter core 2 to more fully contact the smoke generated from the heating channel 1b, thereby improving the filtering efficiency and reducing the passage of harmful substances. By increasing the cross-sectional area, the filter core 2 can better disperse the particulate matter in the smoke, reducing the possibility of local blockage and prolonging the service life of the filter core 2. The larger cross-sectional area can reduce the resistance of the smoke during transmission, allowing the smoke to pass through the filter core 2 more smoothly and improving the user experience. The difference in cross-sectional area between the filter core 2 and the heating channel 1b can better adapt to the flow changes of the smoke, ensuring the stability of the device under different use conditions.
[0031] In an embodiment of the present application, please refer to Figure 2 and Figure 3 The body 1 further comprises a sealing member 15, which is arranged around the heating channel 1b, and the sealing member 15 is located at one end of the holding portion 11 close to the rotating portion 12.
[0032] In this embodiment, the body 1 further comprises a sealing member 15 arranged around the heating channel 1b at one end of the holding portion 11 close to the rotating portion 12. This design ensures the sealing of the heating channel 1b from the outside by the arrangement of the sealing member 15, preventing smoke leakage. Specifically, the sealing member 15 can be made of elastic material (such as rubber or silicone), arranged around the outer periphery of the heating channel 1b, and installed at one end of the holding portion 11 close to the rotating portion 12. When the rotating portion 12 is connected with the holding portion 11, the sealing member 15 can tightly fit the inner wall of the rotating portion 12, thereby achieving good sealing effect. The arrangement of the sealing member 15 effectively prevents smoke from leaking from the gap between the heating channel 1b and the rotating portion 12, ensuring that the smoke can only be discharged through the filter element 2 and the smoke outlet 12a, improving the sealing performance of the device and the user experience. Good sealing performance reduces the potential impact of smoke leakage on the internal structure of the device, while avoiding the contact of smoke with the user's hands, improving the safety of device use. The sealing member 15 can prevent foreign matter from entering the heating channel 1b, reducing pollution to the heating assembly 3, thereby prolonging the service life of the device.

The sealing protrusion 121 is arranged at the end of the rotating portion 12, which is matched with the sealing member 15 in shape and can tightly fit the surface of the sealing member 15. The sealing protrusion 121 can be a protruding arc surface or a sharp corner, and the corresponding position of the sealing member 15 also has a matching elastic structure; when the rotating portion 12 is connected with the holding portion 11, the sealing protrusion 121 abuts against the sealing member 15 to form a sealing structure. The cooperation of the sealing protrusion 121 and the sealing member 15 can effectively prevent smoke from leaking from the gap between the filter cavity 1a and the heating channel 1b, ensuring that the smoke can only be discharged through the predetermined path, improving the sealing performance and use safety of the device. Through the design of the sealing protrusion 121, good sealing effect can be achieved without additional sealing devices, simplifying the overall structure and reducing production cost. The tight cooperation of the sealing protrusion 121 and the sealing member 15 reduces the possibility of smoke leakage, avoids the contact of smoke with the user's hands, and improves the user's experience.
