Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette device technology, and in particular to a cartridge structure and a cartridge-based electronic cigarette atomizing device. Background Technology

[0002] Currently, most refillable e-cigarette cartridges on the market use a single silicone T-stop sealing solution, which means that a silicone T-stop is only placed at the mouth of the cartridge to achieve a seal. However, since this sealing method only seals at the mouth, a large cavity is still formed inside the cartridge's airway. This results in a large space for e-liquid to flow during transportation and storage, making it prone to irregular flow due to factors such as shaking and temperature changes. This can lead to problems such as e-liquid leakage and uneven wetting of the atomizer core, ultimately affecting the stability of the product's performance and its reliability. Utility Model Content

[0003] The main purpose of this utility model is to provide a cartridge structure and a replaceable cartridge electronic atomizing device, aiming to solve the technical problem that the existing replaceable cartridges only use silicone T-shaped plugs to seal the mouth, leaving the airway cavity still relatively large, which easily leads to e-liquid leakage and affects the stability and reliability of the product.

[0004] In order to achieve the above-mentioned utility model objectives, this utility model proposes a cigarette cartridge structure, including a cigarette cartridge mouthpiece, an airway sealing assembly, and an atomizing base device;

[0005] The cartridge mouthpiece is detachably connected to the atomizing base device. The cartridge mouthpiece is provided with a cartridge air passage, and the cartridge air passage is connected to the atomizing base device.

[0006] The airway sealing assembly is disposed within the airway of the cartridge, extends along the entire length of the airway, and is detachably and sealingly connected to one end of the airway near the atomizing base device.

[0007] Furthermore, the airway sealing assembly includes a first sealing part, a second sealing part, and a third sealing part;

[0008] The first sealing part is connected to the third sealing part through the second sealing part. The width of the second sealing part increases from the first sealing part to the third sealing part, and the sides of the first sealing part and the third sealing part are parallel to each other.

[0009] Furthermore, the airway sealing assembly also includes a plurality of airway sealing rings, which are spaced apart on the third sealing portion. The airway sealing rings are used to contact the sidewall of the airway when the third sealing portion is located inside the airway of the cartridge.

[0010] Furthermore, the cartridge mouthpiece includes a connecting portion and a contact portion integrally connected to the connecting portion. The cartridge air passage is disposed within the contact portion and extends along the entire length of the contact portion. A receiving space communicating with the cartridge air passage is formed within the connecting portion. The atomizing base device is located within the receiving space and snapped together with the connecting portion.

[0011] Furthermore, the atomizing base device includes a base sealing assembly, which includes a cartridge base and a base oil sealing part;

[0012] The cartridge base is snapped to the end of the connecting part away from the contact part. The oil-sealing part of the base is sleeved on the cartridge base to form an atomizing chamber that is connected to the air passage of the cartridge. The side and top of the oil-sealing part of the base abut against the connecting part and the contact part, respectively.

[0013] Furthermore, the oil-sealing part of the base includes an oil-sealing body and a first sleeve, and the atomizing base device includes an atomizing condensation component, which includes oil-absorbing cotton.

[0014] The sealing body is integrally connected to the first sleeve, the first sleeve abuts against the connecting part, the sealing body abuts against the contact part, the first sleeve is provided with a receiving groove, the oil-absorbing cotton is disposed in the receiving groove, and the receiving groove and the oil-absorbing cotton are sequentially connected to the air passage of the e-cigarette cartridge.

[0015] Furthermore, the cartridge base includes a base body and a second sleeve, and the atomizing condensation assembly also includes an atomizing core and condensation cotton;

[0016] The base body is snapped to the end of the connecting part away from the contact part. The second sleeve is integrally connected to the base body and is sleeved inside the first sleeve. The condensation cotton is detachably disposed inside the base body. The base body extends toward the atomizing chamber to form a support plate. The atomizing core is located inside the atomizing chamber and abuts against the support plate and the sealing body.

[0017] Furthermore, the cartridge structure also includes a sealing ring, a cartridge electrode, and a plurality of magnets disposed within the base body. The sealing ring, the cartridge electrode, and the magnets are located on the side of the condensation cotton away from the atomizing core. The cartridge electrode is connected to the atomizing core and is located between adjacent magnets.

[0018] Furthermore, the cartridge structure also includes a dust cover, which is disposed on the side of the base body away from the oil sealing part of the base, and is fitted on the side of the connecting part away from the contact part.

[0019] This utility model also proposes a cartridge-type electronic cigarette atomizing device, including the cartridge structure described in any of the above embodiments.

[0020] Beneficial effects:

[0021] This utility model discloses a cartridge structure, including a cartridge mouthpiece, an airway sealing assembly, and an atomizing base device. The cartridge mouthpiece is detachably connected to the atomizing base device, and an airway is provided inside the cartridge mouthpiece, which is connected to the atomizing base device. The airway sealing assembly is disposed within the cartridge airway, extends along the entire length of the cartridge airway, and is detachably and sealingly connected to one end of the cartridge airway near the atomizing base device. By extending along the entire length of the cartridge airway, the airway sealing assembly completely fills the airway cavity, improving the product's sealing performance. Compared to traditional T-shaped plugs that only seal the opening, it significantly reduces the volume of the cavity within the airway, not only reducing the space for e-liquid flow during transportation and storage but also lowering the risk of e-liquid leakage due to vibration or tilting, making the entire device more stable and reliable under various operating conditions.

[0039] Reference Figures 1-3 This embodiment provides a cigarette cartridge structure, including a cigarette cartridge mouthpiece 1, an airway sealing assembly 2, and an atomizing base device;

[0040] The cartridge mouthpiece 1 is detachably connected to the atomizing base device. The cartridge mouthpiece 1 is provided with a cartridge air passage 12, and the cartridge air passage 12 is connected to the atomizing base device.

[0041] The airway sealing assembly 2 is disposed within the airway 12 of the cartridge, and extends along the entire length of the airway 12 of the cartridge, and is detachably and sealingly connected to one end of the airway 12 of the cartridge near the atomizing base device.

[0042] In the above embodiment, the cartridge structure includes a cartridge mouthpiece 1, an airway sealing assembly 2, and an atomizing base device. The cartridge mouthpiece 1 is the part that the user directly contacts and is used to inhale the vapor generated by the atomizing base device. It has a cartridge airway 12 that communicates with the atomizing base device, ensuring a smooth path for the e-liquid to be transferred from the atomizing base device to the user. The cartridge airway 12 extends along the length of the cartridge mouthpiece 1. The airway sealing assembly 2 is a rod-shaped structure made of silicone material. This assembly extends along the entire length of the cartridge airway 12 and is tightly installed in the cartridge airway 12 near the atomizing base device. At one end, the airway sealing component 2 not only completely fills the space of the cartridge airway 12, but also effectively prevents e-liquid leakage. Since the length of the airway sealing component 2 is greater than the cartridge airway 12, it actually extends beyond the top of the cartridge airway 12. The detachable connection of the cartridge mouthpiece 1 to the atomizing base device is preferably a snap-fit ​​connection. The detachable sealing connection of the airway sealing component 2 to the end of the cartridge airway 12 near the atomizing base device is preferably a plug-in connection. Simultaneously, the airway sealing component 2 is connected to the bottom of the cartridge airway 12, completely blocking the cartridge airway 12. Therefore, by extending along the entire length of the cartridge airway 12, the airway cavity is completely filled, improving the product's sealing performance. Compared to traditional T-shaped plugs that only seal the opening, this significantly reduces the volume of the cavity within the airway, reducing the space for e-liquid flow during transportation and storage, and lowering the risk of e-liquid leakage due to vibration or tilting. This makes the entire device more stable and reliable under various usage conditions.

[0043] Reference Figures 1-2 In one embodiment, the airway sealing assembly 2 includes a first sealing part 20, a second sealing part 21, and a third sealing part 22;

[0044] The first sealing part 20 is connected to the third sealing part 22 through the second sealing part 21. The width of the second sealing part 21 increases from the first sealing part 20 to the third sealing part 22, and the sides of the first sealing part 20 and the third sealing part 22 are parallel to each other.

[0045] In the above embodiment, the airway sealing assembly 2 includes a first sealing part 20, a second sealing part 21, and a third sealing part 22. These three parts together form an integral circular silicone rod structure. The first sealing part 20 is located at the front end of the airway sealing assembly 2 and has the smallest cross-sectional diameter. As it moves backward to the second sealing part 21, the cross-sectional diameter gradually increases, forming a conical transition area, which helps to smoothly transition and gradually fill the space of the cartridge airway 12. Finally, the third sealing part 22 has the largest cross-sectional diameter, and its side is spatially parallel to the side of the first sealing part 20. This means that from the first sealing part 20 to the third sealing part 22, the gap between the airway sealing assembly 2 and the inner wall of the cartridge airway 12 will gradually decrease, eventually reaching the tightest fit. This progressive sealing design not only ensures the stability and reliability of the airway sealing assembly 2 in the entire length direction, but also effectively reduces the risk of e-liquid leakage caused by vibration or tilting.

[0046] Reference Figures 1-2 In one embodiment, the airway sealing assembly 2 further includes a plurality of airway sealing rings 23, which are spaced apart on the third sealing portion 22. The airway sealing rings 23 are used to contact the sidewall of the airway 12 when the third sealing portion 22 is located inside the cartridge airway 12.

[0047] In the above embodiment, the airway sealing assembly 2 further includes a plurality of airway sealing rings 23. These airway sealing rings 23 are circular in structure and extend along the entire circumference of the third sealing portion 22. The plurality of airway sealing rings 23 are disposed on the outer periphery of the third sealing portion 22. These airway sealing rings 23 are evenly distributed along the entire length of the third sealing portion 22 and are equidistantly disposed on the third sealing portion 22 at specified intervals. Each airway sealing ring 23 is made of soft silicone material, which has good elasticity and flexibility, and can provide a tight fit without damaging the inner wall of the cartridge airway 12. The sealing effect is achieved by the first sealing part 20, the second sealing part 21, and the third sealing part 22, together with the airway sealing rings 23, forming a single integrated piece that ensures seamless connection and coordinated operation between the various parts. Because the airway sealing rings 23 are made of soft silicone material, when the third sealing part 22 is inserted into the airway 12 of the cartridge, it can effectively contact the side wall of the airway 12 of the cartridge to adapt to different sizes of airway 12 of the cartridge, ensuring that even with slight manufacturing tolerances, a good sealing effect can be maintained, thereby significantly reducing the flow space of e-liquid in the airway 12 of the cartridge and reducing the risk of leakage.

[0048] Reference Figure 1 , Figure 3In 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 12 is disposed in the contact portion 11 and extends along the entire length of the contact portion 11. The connecting portion 10 has a receiving space that communicates with the cartridge air passage 12. The atomizing base device is located in the receiving space and is snap-fitted to the connecting portion 10.

[0049] In the above embodiment, the cartridge mouthpiece 1 consists of a connecting part 10 and a contact part 11. The connecting part 10 is the key part for connecting the cartridge mouthpiece 1 with the atomizing base device. The cartridge air passage 12 is disposed in the contact part 11. The cartridge air passage 12 extends along the entire length of the contact part 11 and is located at the center of the contact part 11, meaning that it connects from one end of the contact part 11 to the other end, forming a complete channel for delivering the atomized e-liquid to the user's mouth, ensuring smooth airflow. The connecting part 10 has a receiving space that communicates with the cartridge air passage 12. When the cartridge mouthpiece 1 is connected to the atomizing base device, the atomizing base device is inserted into the receiving space in the connecting part 10 and firmly fixed by a snap-fit ​​mechanism, ensuring a tight and stable connection between the cartridge mouthpiece 1 and the atomizing base device, greatly improving the convenience of use and the durability of the product.

[0050] Reference Figure 1 , Figure 3 In one embodiment, the atomizing base device includes a base sealing assembly 30, which includes a cartridge base 301 and a base oil sealing part 302.

[0051] The cartridge base 301 is snapped to the end of the connecting part 10 away from the contact part 11. The base oil sealing part 302 is sleeved on the cartridge base 301 to form an atomizing chamber 303 that is connected to the cartridge air passage 12. The side and top of the base oil sealing part 302 abut against the connecting part 10 and the contact part 11, respectively.

[0052] In the above embodiment, the atomizing base device includes a base sealing assembly 30, which in turn includes a cartridge base 301 and a base oil sealing part 302. The cartridge base 301 is fixed to the end of the connecting part 10 of the cartridge mouthpiece 1 away from the contact part 11 by a snap-fit ​​connection, ensuring a firm connection between the cartridge base 301 and the connecting part 10, and facilitating disassembly and replacement. The base oil sealing part 302 is sleeved on the cartridge base 301, forming an atomizing chamber 303. The atomizing chamber 303 is connected to the cartridge air passage 12, thereby ensuring that the atomized e-liquid can smoothly enter the cartridge air passage 12 and finally reach the user's mouth.

[0053] The cartridge base 301 is located at the bottom of the connecting part 10. The top center of the base sealing part 302 has a through hole with the same diameter as the cartridge airway 12. The top center of the base sealing part 302 has a through hole that communicates with the cartridge airway 12. The two holes have the same diameter. This through hole allows the atomizing chamber 303 to be directly connected to the cartridge airway 12, ensuring smooth transmission of airflow and atomized e-liquid. At the same time, the side of the base sealing part 302 is tightly fitted to the inner wall of the connecting part 10, forming an effective sealing barrier to prevent any possible leakage. In addition, the top of the base sealing part 302 abuts against the bottom of the contact part 11, ensuring that the path from the cartridge base 301 to the cartridge airway 12 is completely sealed, avoiding possible e-liquid leakage during use. Furthermore, since the base sealing part 302 and the cartridge base 301 are connected by a nesting method, this not only simplifies the assembly process but also improves the convenience of maintenance and replacement.

[0054] Reference Figure 1 , Figure 3 In one embodiment, the base sealing part 302 includes an oil sealing body 3020 and a first sleeve 3021, and the atomizing base device includes an atomizing condensation component 31, which includes an oil-absorbing cotton 310.

[0055] The sealing body 3020 is integrally connected to the first sleeve 3021. The first sleeve 3021 abuts against the connecting part 10. The sealing body 3020 abuts against the contact part 11. The first sleeve 3021 is provided with a receiving groove. The oil-absorbing cotton 310 is disposed in the receiving groove. The receiving groove and the oil-absorbing cotton 310 are sequentially connected to the air passage 12 of the e-cigarette cartridge.

[0056] In the above embodiment, the base sealing part 302 consists of two parts: a sealing body 3020 and a first sleeve 3021. The sealing body 3020 and the first sleeve 3021 are integrally connected. The first sleeve 3021 extends from the sealing body 3020 away from the contact part 11. The top of the sealing body 3020 abuts against the bottom of the contact part 11, while the first sleeve 3021 is responsible for tightly fitting against the inner wall of the connecting part 10. The first sleeve 3021 has a receiving groove inside, which is used to place oil-absorbing cotton 310. The oil-absorbing cotton 310 can effectively absorb oil. The container collects excess e-liquid and prevents it from entering the airway and causing leakage. The bottom of the container is directly connected to the airway 12 of the cartridge. This ensures that when the absorbent cotton 310 is placed in the container, the e-liquid can flow smoothly from the airway 12 of the cartridge into the absorbent cotton 310 without stagnating in the airway. In addition, the absorbent cotton 310 is also provided with through holes, so that a continuous channel is formed between the container, the absorbent cotton 310 and the airway 12 of the cartridge. It is also connected to the atomizing chamber 303, ensuring that the airflow and atomized e-liquid can be smoothly transmitted, bringing users a more convenient and comfortable smoking experience.

[0057] Reference Figure 1 , Figure 3 In one embodiment, the cartridge base 301 includes a base body 3010 and a second sleeve 3011, and the atomizing condensation assembly 31 further includes an atomizing core 311 and a condensation cotton 312.

[0058] The base body 3010 is snapped to the end of the connecting part 10 away from the contact part 11. The second sleeve 3011 is integrally connected to the base body 3010 and is sleeved inside the first sleeve 3021. The condensing cotton 312 is detachably disposed inside the base body 3010. The base body 3010 extends toward the atomizing chamber 303 to form a support plate 3012. The atomizing core 311 is located inside the atomizing chamber 303 and abuts against the support plate 3012 and the sealing body 3020.

[0059] In the above embodiment, the cartridge base 301 includes a base body 3010 and a second sleeve 3011. The atomizing and condensing assembly 31 also includes an atomizing core 311 and a condensing cotton 312. The base body 3010 is fixed to the end of the connecting part 10 away from the contact part 11 by a snap-fit ​​connection, ensuring a firm connection between the cartridge base 301 and the connecting part 10. The second sleeve 3011 is integrally connected to the base body 3010 and is designed as a circular cylindrical structure, located in the direction of the base body 3010 toward the sealing body 3020, and its position is at the edge of the base body 3010.

[0060] The second sleeve 3011 can be fitted inside the first sleeve 3021. The condensing cotton 312 is detachably installed inside the base body 3010 to absorb excess liquid formed by condensation. A support plate 3012 extends from the base body 3010 toward the atomizing chamber 303. The support plate 3012 is also a cylindrical structure, with the same center as the second sleeve 3011, but its diameter and height are smaller than those of the second sleeve 3011. The function of the support plate 3012 is to provide a stable support platform for the atomizing core 311, so that it can be stably installed in the atomizing chamber 303. The atomizing core 311 abuts between the support plate 3012 and the sealing body 3020 to ensure the best atomization effect.

[0061] In addition, the airflow channel 12 of the cartridge is a straight channel. When the user uses it, the mouth directly contacts the outlet end of the airflow channel 12. The airflow channel 12 is inclined downward relative to the human body, so that the liquid condensed on the inner wall of the airflow channel 12 can flow down naturally and be absorbed by the oil-absorbing cotton 310 away from the outlet end of the airflow channel 12. This design not only improves the comfort of use, but also effectively prevents the condensate from affecting the smoking experience, and further improves the overall performance of the device.

[0062] Reference Figure 1 , Figure 3 In one embodiment, the cartridge structure further includes a sealing ring 4, a cartridge electrode 5, and a plurality of magnets 6 disposed within the base body 3010. The sealing ring 4, the cartridge electrode 5, and the magnets 6 are located on the side of the condenser cotton 312 away from the atomizing core 311. The cartridge electrode 5 is connected to the atomizing core 311, and the cartridge electrode 5 is located between adjacent magnets 6.

[0063] In the above embodiment, the cartridge structure further includes a sealing ring 4, a cartridge electrode 5, and multiple magnets 6. These components are all disposed within the base body 3010 and located on the side of the condensation cotton 312 away from the atomizing core 311. The sealing ring 4 is a key component that is detachably installed within the base body 3010 via a slot. It is made of elastic material and can effectively fill any possible tiny gaps. The diameter of the sealing ring 4 is designed to be smaller than the diameter of the cross-section of the base body 3010. The cartridge electrode 5 is one of the important components responsible for power transmission in the electronic cigarette device. It is connected to the atomizing core 311 and provides the necessary power transmission support for the atomization process. The cartridge electrode 5 is embedded within the base body 3010 and is surrounded by multiple magnets 6. The diameter of the circle formed by the multiple magnets 6 is smaller than or equal to the diameter of the sealing ring 4 in space. This makes the sealing ring 4 positioned above the magnets 6, thus forming a layered internal structure. This avoids component displacement caused by accidental collisions or vibrations, achieves efficient integration of the overall structure, and improves the reliability and durability of the device.

[0064] Reference Figure 1 , Figure 3 In one embodiment, the cartridge structure further includes a dust cover 7, which is disposed on the side of the base body 3010 away from the base oil sealing part 302, and is sleeved on the side of the connecting part 10 away from the contact part 11.

[0065] In the above embodiment, the cartridge structure also includes a dust cover 7, which is a circular sleeve made of silicone material. It is designed to protect the electronic cigarette device from external dust and other contaminants. The dust cover 7 is located on the side of the base body 3010 away from the base sealing part 302 and is fitted on the side of the connecting part 10 away from the contact part 11. This ensures that the dust cover 7 can effectively cover the interface area between the connecting part 10 and the base body 3010, preventing dust or other small particles from entering the device and affecting its performance. The bottom of the dust cover 7 is connected to the bottom of the base body 3010, while its two sides are fixed to the outer side wall of the bottom of the connecting part 10, forming a tightly fitting protective barrier, which effectively enhances the product's protective capabilities.

[0066] This embodiment also proposes a cartridge-type electronic cigarette atomizing device, including the cartridge structure described in any of the above embodiments, which not only improves the user experience and convenience, but also significantly enhances the safety, reliability and durability of the device.
