Description

Technical Field

[0001] This application relates to the field of electronic cigarettes, and in particular to an electronic cigarette atomizing core. Background Technology

[0002] In the e-cigarette industry, the atomizer coil, as a core component, directly impacts the user experience. Currently, some e-cigarette products on the market employ multi-coil structures to pursue richer flavors and greater usability. This structure, through the coordinated work of multiple atomizer coils, can produce diverse vapor effects at different power levels and temperatures, thereby satisfying users' multi-layered flavor preferences. However, while multi-coil structures theoretically enhance the user experience, they present numerous problems in practical applications.

[0003] First, multi-atomizing core structures typically require multiple cartridges stacked together (see attached). Figure 1 This not only increases the manufacturing cost of the product but also complicates the production process. Each cartridge requires precise manufacturing and assembly to ensure its compatibility with the atomizer core, which undoubtedly increases production difficulty and cost. Secondly, the connection of multiple airflow channels is also a significant factor affecting user experience. In multi-atomizer core structures, the airflow channels typically need to be connected in segments to ensure that vapor flows smoothly from each atomizer core. However, this segmented connection often leads to uneven airflow, causing resistance during vapor flow and affecting the uniformity of vapor and flavor. Furthermore, air leakage may occur at the airflow channel connections, further reducing the user experience.

[0004] These problems not only limit the application of multi-atomizing core structures in e-cigarettes but also affect the overall market competitiveness of e-cigarette products. Therefore, developing a new type of e-cigarette atomizing core to address the shortcomings of existing technologies has significant practical importance and market value. Utility Model Content

[0005] The purpose of this application is to overcome at least one deficiency of the existing technology and provide an electronic cigarette atomizing core that uses an integrated structure to replace the traditional split combination structure, thereby achieving more efficient gas flow. At the same time, the structure is simple, the production cost is low, and it is conducive to the widespread application of industrial production.

[0006] To achieve the above objectives, this application discloses an electronic cigarette atomizing core. The electronic cigarette includes a main body with a working air passage, an oil tank disposed within the main body for storing oil, and an atomizing working part located within the working air passage. At least two atomizing working parts are arranged at intervals along the axial direction w within the working air passage. Correspondingly, the oil tank is divided into sub-oil tanks by a partition corresponding to the number of atomizing working parts. Each sub-oil tank is independently connected and cooperates with at least one atomizing working part for supplying oil to the corresponding atomizing working part. Correspondingly, the working air passage has an oil outlet port connecting to the sub-oil tanks. The main body is also provided with an interface or terminal electrically connected to the atomizing working part, and the interface or terminal realizes electrical connection with external power supply components or assemblies.

[0007] Furthermore, the atomizing working part is a heating wire mesh.

[0008] As an optional technical solution, each atomizing working part is connected and cooperated with the corresponding oil tank through an independent oil storage cotton core, and the oil storage cotton core realizes the oil supply to the atomizing working part.

[0009] As an optional technical solution, the working air passage passes through the oil tank. Preferably, the body has a groove, the open end of which is sealed by a cover plate to form an oil tank; a hollow tube is inserted into and passes through the oil tank, forming a working air passage; at least one partition is provided inside the oil tank to divide it into multiple sub-oil tanks.

[0010] Compared with the prior art, this application has at least one of the following beneficial effects:

[0011] 1. The adoption of an integrated structure to replace the traditional split-type combination structure simplifies the production process, reduces production costs, and facilitates the popularization and application of industrial production.

[0012] 2. Multiple atomizing working sections spaced axially within the working air passage, along with sub-oil chambers separated by partitions, enable independent oil supply and efficient atomization, improving the uniformity and flavor of the smoke.

[0013] 3. By connecting the independent oil storage cotton core with the sub-oil tank, the oil supply efficiency is optimized, ensuring the stable operation of the atomization working part and avoiding airflow problems and air leakage caused by multi-stage airway connections.

[0014] 4. The compact structural design makes installation and maintenance more convenient, providing users with a smoother and more reliable user experience and enhancing the product's market competitiveness.

[0023] See attached document Figure 2This embodiment discloses an electronic cigarette atomizing core, whose structural design is based on the concept of integrated design, aiming to solve the problems of high cost, complex process and obstructed airflow in the existing multi-atomizing core structure. The electronic cigarette atomizing core is mainly composed of a body 1, an atomizing working part 3, a cover plate 4, a partition plate 5, and a hollow tube 9. The components are precisely matched to achieve efficient atomization and stable oil supply.

[0024] Specifically, in this embodiment, the body 1, as the core support structure, is made of a material with high temperature resistance and good insulation properties, such as food-grade plastic or ceramic. The body 1 has a recessed groove, for example a circular groove, with a pre-set upward-through outlet 10 at the bottom for connecting to the working air passage 8. An installation groove 6 is provided at the outlet 10 at the bottom of the groove for fixing the hollow tube 9. A silicone sealant 7 is provided inside the installation groove 6 to ensure a sealed connection between the hollow tube 9 and the outlet 10. The hollow tube 9 is made of a material with high temperature resistance and good chemical stability, such as stainless steel or aluminum alloy. It is inserted into the installation groove 6 and connected to the outlet 10 using its hollow structure, forming a continuous working air passage 8. This design not only simplifies the air passage structure but also avoids airflow obstruction and leakage problems caused by connecting multiple air passages.

[0025] See attached document Figure 1 In this embodiment, the oil tank is formed by a groove in the main body 1. The opening end of the groove is sealed by a silicone cover plate 4, forming a sealed cavity structure. In the case of a circular groove, the cavity is a cylindrical oil tank for storing e-liquid. The cover plate 4 has an opening that mates with a hollow tube 9. The inner edge of the opening is in close contact with the outer wall of the hollow tube 9, forming a sealed structure. The hollow tube 9 needs to extend out of the oil tank or at least be flush with the oil tank to meet the needs of use and sealing. Multiple partitions 5 are provided inside the oil tank. The partitions 5 are also made of silicone, and their outer edges are sealed to the inner wall of the oil tank. The partitions 5 have openings that fit the hollow tube 9. The openings are sealed to the hollow tube 9, dividing the oil tank into multiple independent sub-oil tanks 2. Each sub-oil tank 2 is connected to a corresponding atomizing working part 3, ensuring that the e-liquid can be independently supplied to each atomizing working part 3.

[0026] In this embodiment, the atomizing working parts 3 are located within the working air passages 8 and are spaced apart along the axial direction. Their core component is a heating wire mesh. The heating wire mesh is made of a high-resistivity metal material, such as a nickel-chromium alloy, which has good heating performance and durability. Each atomizing working part 3 is connected to its corresponding sub-oil chamber 2 via an independent oil-absorbing cotton core (not shown in the figure). The oil-absorbing cotton core is made of a high-oil-absorbing fiber material, such as cotton or ceramic fiber, which can quickly absorb oil and transport it to the heating wire mesh. The main body 1 is also provided with an interface 11 for electrical connection with an external power supply component, providing the necessary electrical energy to the atomizing working parts 3. The specific design of the interface 11 is well-known to those skilled in the art and will not be described in detail here.

[0027] It should be understood that the oil supply structure between the sub-oil tank 2 and the atomizing working part 3, as well as the oil flow mode, are well known to those skilled in the art. This embodiment does not describe them in further detail because this part belongs to the publicly known technology.

[0028] To ensure the safe operation of the electronic cigarette atomizing core, insulation between the hollow tube 9 and the atomizing working part 3 is achieved through material selection and structural design. The hollow tube 9 is made of materials with good insulation properties, such as ceramics or high-temperature resistant plastics (e.g., polyetheretherketone, PEEK). These materials not only withstand high-temperature environments but also have good electrical insulation properties, effectively preventing electrical conduction between the hollow tube 9 and the atomizing working part 3, thereby preventing short circuits.

[0029] Furthermore, the connection structure between the hollow tube 9 and the atomizing working part 3 is also carefully designed to ensure insulation performance. The atomizing working part 3 is typically composed of a heating wire mesh, which is electrically connected to an external power supply component via an interface 11. In this embodiment, the heating wire mesh is fixed within the working air passage 8 by an insulating bracket, which is made of the same insulating material as the hollow tube 9, such as ceramic or high-temperature resistant plastic. The design of the insulating bracket not only secures the heating wire mesh but also ensures a certain insulating distance between it and the hollow tube 9, preventing direct contact.

[0030] During the actual assembly process, the insulation performance between the hollow tube 9 and the atomizing working part 3 is ensured through the following steps: First, the heating wire is fixed on the insulating bracket to ensure that it has no direct contact with the hollow tube 9; second, the insulating bracket is installed into the working air passage 8, and its position is ensured to be stable through precision assembly; finally, the heating wire is connected to the external power supply component through the interface 11 to complete the electrical conduction. Throughout the entire assembly process, the hollow tube 9 and the atomizing working part 3 remain insulated from each other, ensuring the safe operation of the equipment.

[0031] In practical use, the user installs the e-cigarette atomizing coil into the e-cigarette device and connects it to an external power supply unit via interface 11. When the user turns on the device, the external power supply unit (specifically the e-cigarette) powers the heating wire, which rapidly heats up, atomizing the e-liquid delivered by the oil reservoir into vapor. The vapor flows out through the working airway 8 for the user to inhale. Because each atomizing section 3 operates independently and the e-liquid is supplied through an independent sub-oil tank 2, the uniformity and flavor of the vapor are significantly improved. Furthermore, the design of the working airway 8 avoids the airflow irregularities and leakage problems caused by connecting multiple airways, further enhancing the user experience.

[0032] The electronic cigarette atomizing core in this embodiment is designed with users' needs for flexibility in mind. Through the multi-electrode tank 2 and the independently controlled atomizing unit 3, it achieves flexible adjustment functions for various usage scenarios. This design not only satisfies users' pursuit of diverse flavors but also allows for adjustment of vapor output according to actual needs, providing users with a more personalized experience.

[0033] In mixed output mode, users can place different flavored e-liquids in different sub-tanks 2. For example, one sub-tank 2 can contain flavored e-liquid A, and another sub-tank 2 can contain flavored e-liquid B. By independently controlling the operating status of each atomizing unit 3, users can achieve mixed output of different flavors. Specifically, the atomization ratio of different flavored e-liquids can be controlled by adjusting the operating time and start-up time of each atomizing unit 3. For example, if the user wants flavor A to be dominant and flavor B to be secondary, they can extend the operating time of the atomizing unit 3 corresponding to flavor A and shorten the operating time of the atomizing unit 3 corresponding to flavor B. Conversely, if the user wants flavor B to be dominant and flavor A to be secondary, they can adjust the operating time of the corresponding atomizing unit 3. This independent control design allows users to flexibly adjust the flavor ratio of the vapor according to their personal preferences, satisfying diverse taste needs.

[0034] In adjustable output mode, users can place e-liquid of the same flavor in different sub-tanks 2. By controlling the operating status of one or more atomizing units 3, users can flexibly adjust the vapor output. For example, if a user wants to reduce vapor output, they can activate only one atomizing unit 3; if a user wants to increase vapor output, they can activate two or more atomizing units 3 simultaneously. This design not only meets the user's needs in different scenarios but also effectively extends the e-liquid's usage time and reduces operating costs.

[0035] As an additional explanation of structures not described in this embodiment, to achieve the aforementioned flexible adjustment functions, the electronic cigarette of this embodiment is generally equipped with a control module. This module connects to an external power supply component via interface 11 and can independently control the working state of each atomizing unit 3. Users can set the working duration and start-up time of each atomizing unit 3 through the control interface or application on the electronic cigarette device, thereby achieving mixed output and adjustable output functions. The specific design of the control module is well-known to those skilled in the art and will not be elaborated here.

[0036] In practical use, users can flexibly adjust the working mode of the e-cigarette coil according to different scenarios and needs. For example, in social situations, users can use the mixed output mode to mix multiple flavored e-liquids to create a unique taste experience and satisfy different users' taste preferences. For personal use, users can use the adjustable output mode to adjust the vapor output according to their own needs, enjoying a rich vapor experience when needed, or reducing vapor output when not needed to save e-liquid.

[0037] The e-cigarette atomizing core of this embodiment simplifies the manufacturing process and reduces production costs through its integrated structure design, while simultaneously improving product performance and reliability. For example, in scenarios where users require multiple flavors, the type of e-liquid in the sub-tank can be adjusted to switch between different flavors, meeting users' personalized needs. Furthermore, due to its compact structure and convenient installation, the e-cigarette atomizing core of this embodiment is suitable for various e-cigarette devices and has broad market application prospects. Through optimized design and material selection, this embodiment not only addresses the shortcomings of existing technologies but also provides a new direction for technological advancement in the e-cigarette industry.

[0038] It should be noted that the parts not disclosed in detail in this embodiment, such as the specific design of interface 11, the connection method of the external power supply component, the specific shape and size of the insulating bracket, and the fixing method of the heating wire, are all well-known or existing technologies for those skilled in the art, and do not need to be described in detail again. The focus of this embodiment is to solve specific problems in the prior art through the design of an integrated structure, and to provide an efficient, reliable, and cost-effective electronic cigarette atomizing core solution.
