[0035] Reference Figures 1-3 This embodiment provides a cigarette cartridge device, including a cigarette cartridge mouthpiece 1, an atomizing component 2, and an oil cup base component 3;

[0036] The cartridge mouthpiece 1 is detachably connected to the oil cup base assembly 3;

[0037] The oil cup base assembly 3 includes a first oil cup base 30 and a second oil cup base 31. The second oil cup base 31 is connected to the end of the first oil cup base 31 near the end of the cartridge mouthpiece 1 where the cartridge air passage 4 is provided. The first oil cup base 30 and the second oil cup base 31 are integral parts.

[0038] The first oil cup base 30 is provided with a single air inlet 32. The atomizing component 2 is arranged in the first oil cup base 30 corresponding to the air inlet 32. The second oil cup base 31 is provided with an atomizing air channel 33. The air inlet 32, the atomizing air channel 33 and the cartridge air channel 4 are connected in sequence.

[0039] In the above embodiments, the cartridge device includes a cartridge mouthpiece 1, an atomizing component 2, and an oil cup base assembly 3. The oil cup base assembly 3 is the basic support structure of the entire device. It consists of a first oil cup base 30 and a second oil cup base 31, and the first oil cup base 30 and the second oil cup base 31 are integrally formed, which enhances the stability and sealing of the overall structure and effectively avoids the loosening or air leakage problems that may occur in traditional split designs. The first oil cup base 30 is provided with a single air inlet 32, which is the only channel for outside air to enter the system. The air inlet 32 ​​is preferably located at the bottom of the first oil cup base 30. The atomizing component 2 is installed inside the first oil cup base 30, at a position corresponding to the air inlet 32, so that the fresh air entering from the air inlet 32 ​​can directly act on the heating element, accelerate the evaporation process of the e-liquid, and form fine smoke. The second oil cup base 31 is provided with an atomizing air guide channel 33. The function of this channel is to connect the air inlet 32 ​​with the cartridge air channel 4 to form a complete airflow transmission system.

[0040] The airflow channel 4 of the cartridge is located inside the cartridge mouthpiece 1 and is connected to the atomizing airflow channel 33. The air inlet 32, the atomizing airflow channel 33, and the cartridge airflow channel 4 are arranged along the same central axis and distributed sequentially from bottom to top. When the user inhales through the cartridge mouthpiece 1, the airflow first enters through the air inlet 32, then passes through the atomizing airflow channel 33, and after the e-liquid is heated and evaporated at the atomizing component 2, it finally rises along the cartridge airflow channel 4 and is ultimately inhaled by the user. Therefore, by making the first oil cup base 30 and the second oil cup base 31 into a single piece, forming an integrated structure, the problem of unstable atomizing chamber space caused by the separate bracket is avoided, reducing material costs and assembly complexity, and improving product stability. At the same time, the single air inlet 32 ​​design, combined with the sequentially connected air inlet 32, atomizing airflow channel 33, and cartridge airflow channel 4, reduces airflow dispersion, lowers the risk of condensate blockage, ensures stable airflow, and thus improves the atomized flavor.

[0041] Reference Figures 1-3 In one embodiment, the first oil cup base 30 includes a support base 301 and an atomizing bracket 302. The atomizing bracket 302 is disposed between the support base 301 and the second oil cup base 31. The air inlet 32 ​​is disposed in the support base 301. The atomizing bracket 302 is provided with an atomizing chamber 303 with openings on both sides. The atomizing component 2 is disposed in the atomizing chamber 303 and is located at one end close to the second oil cup base 31.

[0042] In the above embodiment, the first oil cup base 30 includes a support base 301 and an atomizing bracket 302. The support base 301 serves as the base and has an air inlet 32 ​​built into it. The air inlet 32 ​​is located at the center of the support base 301 and extends through the entire height direction of the support base 301. The atomizing bracket 302 is disposed between the support base 301 and the second oil cup base 31. The second oil cup base 31, the atomizing bracket 302, and the support base 301 are a single unit. The atomizing bracket 302 has an atomizing chamber 303 with openings on both sides. These two openings are located on opposite sides along the length direction of the atomizing bracket 302. Furthermore, the front opening is larger than the back opening; the atomizing component 2 is placed inside the atomizing chamber 303 and near one end of the second oil cup base 31, which maximizes the use of fresh air entering from the air inlet 32 ​​for heating and evaporating the e-liquid; since the support base 301 and the atomizing bracket 302 are designed as a single piece, no additional fixing device is required between them, which enhances the structural robustness and sealing. In addition, the openings on both sides of the atomizing chamber 303 effectively guide the direction of airflow, allowing the air to be evenly distributed inside the atomizing chamber 303, enhancing the atomization effect, and also facilitating the installation of the atomizing component 2.

[0043] Reference Figures 1-3In one embodiment, the atomizing air channel 33 includes a first atomizing air channel 330 and a second atomizing air channel 331. The first atomizing air channel 330 passes through the opposite two sides of the second oil cup base 31 and is connected to the atomizing chamber 303. The second atomizing air channel 331 is located at one end of the second oil cup base 31 away from the atomizing bracket 302 and is connected to the first atomizing air channel 330.

[0044] In the above embodiment, the atomizing air channel 33 includes a first atomizing air channel 330 and a second atomizing air channel 331. The first atomizing air channel 330 passes through the opposite sides of the second oil cup base 31, realizing direct communication with the atomizing chamber 303. The two openings of the first atomizing air channel 330 are located on opposite sides of the second oil cup base 31 along its length, and the opening sizes are the same, so that the openings on both sides of the first atomizing air channel 330 are connected to the openings on both sides of the atomizing chamber 303. The second atomizing air channel 331 is located at the end of the second oil cup base 31 away from the atomizing bracket 302, specifically at the top of the second oil cup base 31. The second atomizing air channel 331 is connected to the first atomizing air channel 330 and is perpendicular to the first atomizing air channel 330 in space. The second atomizing air channel 331 guides the airflow that has undergone preliminary treatment (i.e., through the first atomizing air channel 330) to the final outlet—the cartridge air channel 4.

[0045] In the entire structure, the air inlet 32, atomizing chamber 303, first atomizing airway 330, second atomizing airway 331, and cartridge airway 4 are sequentially connected, forming a complete airflow path. When air enters through the air inlet 32, it first reaches the atomizing chamber 303, where it mixes with the heated e-liquid and transforms into atomized gas. This gas then passes through the first atomizing airway 330, where its openings on both sides ensure uniform dispersion. It then enters the second atomizing airway 331 for directional adjustment and finally rises along the cartridge airway 4 until it is inhaled by the user. The close cooperation between all components ensures smooth airflow and minimal energy loss, effectively guaranteeing unobstructed airflow.

[0046] Reference Figures 1-4 In one embodiment, the atomizing component 2 includes a heating element 20 and a first sealing element 21. The first sealing element 21 is detachably connected to one end of the atomizing chamber 303 near the second oil cup base 31. The heating element 20 is detachably connected inside the first sealing element 21 and forms a specified interval with one end of the atomizing chamber 303 near the support base 301.

[0047] In the above embodiments, the atomizing component 2 includes a heating element 20 and a first sealing element 21. The first sealing element 21 is made of silicone, which has good elasticity and sealing performance. Its shape is rectangular, matching the internal shape of the atomizing chamber 303, and can fit tightly against the top wall and part of the side wall of the atomizing chamber 303. That is, the connection method of the first sealing element 21 detachably connected to the atomizing chamber 303 is preferably an interference fit, which effectively prevents e-liquid leakage or condensate seepage into other components. The first sealing element 21 has a receiving groove inside for installing the heating element 20; The heating element 20 is the core component of the atomization process. It uses electric heating to evaporate the e-liquid into fine particles, thereby forming inhalable smoke. The heating element 20 is preferably fixed in the receiving groove of the first sealing element 21 by a snap-fit ​​connection. That is, the connection method of the heating element 20 being detachably connected in the first sealing element 21 is preferably a snap-fit ​​connection. Furthermore, there is a certain gap between the heating element 20 and the bottom of the atomization chamber 303. This gap design is to ensure that air can flow directly from the air inlet 32 ​​to the heating element 20, thereby improving heating efficiency and atomization effect, while simplifying the maintenance and installation process.

[0048] Reference Figures 1-3 In one embodiment, the second oil cup base 31 is provided with a plurality of first oil inlet holes 34, and the first sealing member 21 is provided with a plurality of second oil inlet holes 22 at one end near the second oil cup base 31, and the first oil inlet holes 34 are connected to the second oil inlet holes 22.

[0049] In the above embodiment, the second oil cup base 31 is provided with a plurality of first oil inlet holes 34. Preferably, there are two first oil inlet holes 34, which are symmetrically arranged on both sides of the second atomizing air passage 331. Each first oil inlet hole 34 penetrates the entire second oil cup base 31. In particular, an arc-shaped guide is added to the design of the first oil inlet hole 34. The guide is located at the bottom of the first oil inlet hole 34, and the opening size at the top of the first oil inlet hole 34 is larger than the opening size at the bottom, which helps to guide the e-liquid to flow out more smoothly and reduce the risk of liquid residue or blockage. In addition, oil storage cotton can be placed inside the first oil inlet hole 34 or it can be directly connected to the oil bottle to ensure A continuous and stable supply of e-liquid is ensured. At the same time, the first sealing element 21 is also provided with multiple second oil inlets 22 at one end near the second oil cup base 31. These holes are arranged one-to-one with the first oil inlets 34. There are also two second oil inlets 22, which are located at the top of the first sealing element 21, corresponding exactly to the position of the first oil inlets 34. This ensures that the e-liquid can flow smoothly from the first oil inlet 34 into the second oil inlet 22 and further flow to the heating element 20. Since the first sealing element 21 is made of silicone, it can ensure a sealed connection between the second oil inlet 22 and the first oil inlet 34, preventing e-liquid leakage or condensate leakage and improving user satisfaction.

[0050] Reference Figures 1-3 In one embodiment, the cartridge device further includes a second seal 5, which is disposed at the end of the second oil cup base 31 away from the first oil cup base 30, and the second seal 5 is arranged correspondingly to the second oil cup base 31.

[0051] In the above embodiment, the cartridge device also includes a second sealing element 5, which is made of silicone. The second sealing element 5 is located at the end of the second oil cup base 31 away from the first oil cup base 30 and is arranged correspondingly to the second oil cup base 31. The second sealing element 5 adopts a rectangular frame structure with partial openings on both sides. The top of the second sealing element 5 is provided with a first through hole corresponding to and communicating with the second atomizing air channel 331, and two second through holes corresponding to and communicating with the first oil inlet 34. The design of the first through hole is to ensure that the atomized gas can smoothly pass through the second atomizing air channel 331 and enter the user's mouth without leakage or blockage. The part with the first through hole is fitted inside the second atomizing air channel 331. At the same time, the number of second through holes corresponds one-to-one with the first oil inlet 34, usually two, and their positions are exactly aligned with the first oil inlet 34, so that the e-liquid can flow smoothly from the oil storage cotton or oil bottle into the heating element 20 for heating and evaporation. Therefore, the second sealing element 5 not only ensures the airtightness of the system, but also provides a reliable guarantee for the supply of e-liquid, improving the working efficiency of the entire device and the user experience.

[0052] Reference Figures 1-3 In one embodiment, the cartridge mouthpiece 1 includes a connecting portion 10 and a contact portion 11 integrally connected to the connecting portion 10. The cartridge air passage 4 is disposed through the contact portion 11.

[0053] In the above embodiment, the cartridge mouthpiece 1 includes a connecting portion 10 and a contact portion 11. The contact portion 11 is the part that the user directly contacts, and the cartridge air passage 4 is located at its center to smoothly guide the atomized gas into the user's mouth. The connecting portion 10 is integrally connected to the contact portion 11, and the second oil cup base 31 is located in a receiving groove inside the connecting portion 10. The receiving groove ensures that the second oil cup base 31 can be stably placed inside the connecting portion 10. At the same time, the second oil cup base 31 with the second sealing member 5 is tightly connected to the contact portion 11 and the connecting portion 10 through the sealing member. The second seal 5 is made of silicone, which ensures a tight fit between the top and sides of the second oil cup base 31 and the contact part 11 and the connecting part 10, preventing any possible leakage or condensate seepage. The end of the connecting part 10 away from the contact part 11 is fixed to the first oil cup base 30 by a snap-fit ​​connection. That is, the bottom of the connecting part 10 sits on the first oil cup base 30, and its inner wall forms a snap-fit ​​connection with the outer side of the first oil cup base 30, making installation and disassembly more convenient, while also providing sufficient firmness to ensure the stability of the equipment during use.

[0054] Reference Figures 1-3 In one embodiment, the cartridge device further includes a sealing ring 6, and a sealing groove 304 is provided at one end of the support base 301 near the atomizing bracket 302. The sealing groove 304 extends along the entire circumference of the support base 301, and the sealing ring 6 is located in the sealing groove 304.

[0055] In the above embodiments, the cartridge device also includes a sealing ring 6; the sealing ring 6 is an annular component made of elastic material, whose main function is to provide additional sealing protection to prevent airflow or liquid leakage. The sealing ring 6 is placed in a sealing groove 304, which is located at one end of the support 301 near the atomizing bracket 302 and extends along the entire circumference of the support 301. The diameter of the sealing ring 6 is smaller than the diameter of the cross-section of the support 301, ensuring that the sealing ring 6 can form a tight fit between the support 301 and the atomizing bracket 302, preventing any possible leakage path.

[0056] Furthermore, the cartridge device also includes an electrode component 7, which is used to effectively transmit electrical energy to the atomizing assembly 2, ensuring that the heating element 20 can work normally to heat the e-liquid and produce an atomization effect.
