Description

Technical Field

[0001] This utility model relates to the field of e-cigarette cartridge technology, specifically to an e-cigarette cartridge, a silicone child lock for the e-cigarette cartridge, and an e-cigarette cartridge filling and exhaust device. Background Technology

[0002] In the current era of rapid development in the e-cigarette industry, e-liquid cartridges, as the core consumable component of e-cigarettes, directly impact product quality and user experience through the efficiency and stability of their filling process. However, existing e-liquid cartridge filling technologies still face many unresolved issues.

[0003] Currently, the mainstream method of filling e-cigarette cartridges relies on manual labor and generally requires complex disassembly operations. For example, some cartridges require separating the mouthpiece from the main structure and removing internal components such as the wicking cotton and atomizer core before the e-liquid filling chamber can be exposed. After filling, the cartridges must be reassembled according to the original steps. The entire process involves multiple delicate operations, which is not only time-consuming but also prone to damage to cartridge components due to improper operation during disassembly and assembly.

[0004] Meanwhile, the venting issue during the refilling process has become a key bottleneck affecting refilling quality. The e-liquid chamber inside the cartridge is not a complete vacuum; a certain amount of air usually remains before refilling. When the refilling device injects e-liquid into the sealed e-liquid chamber, the internal gas is compressed, and the pressure gradually increases. Due to flaws in the venting design of existing refilling devices, overflowing e-liquid often seeps into the cartridge's circuit interface and atomizing components, affecting the normal use of the cartridge and causing e-liquid to be sucked in during vaping, thus reducing the user experience.

[0005] Therefore, we have proposed a cartridge, a silicone child lock for the cartridge, and a cartridge filling and venting device to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a tobacco cartridge, a silicone child lock for the tobacco cartridge, and a tobacco cartridge filling and venting device to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: a cigarette cartridge, including a bottom cover, wherein an oil-absorbing cotton is fixedly connected inside the bottom cover, and an oil tank sealing silicone is embedded inside the bottom cover, wherein the oil-absorbing cotton is located between the bottom cover and the oil tank sealing silicone;

[0010] Magnets are symmetrically and fixedly connected to the bottom end of the bottom cover, and electrodes are symmetrically and fixedly connected to the bottom end of the bottom cover, with the electrodes located inside the magnets; insulating silicone is provided on the sealing silicone of the oil tank.

[0011] Preferably, a bracket is fixedly fitted onto the insulating silicone, an inner cotton liner is provided inside the bracket, a heating wire is provided inside the inner cotton liner, and an outer cotton liner is fitted onto the outside of the bracket.

[0012] Preferably, the outer surface of the outer cotton is fitted with an atomizing core cover, the atomizing core cover has grooves evenly spaced on it, a sealing ring is fitted into the grooves of the atomizing core cover, and an e-liquid chamber is provided on the bottom cover.

[0013] Preferably, the side walls of the e-liquid tank are symmetrically arranged.

[0014] The e-liquid cartridge has a silicone child lock, which is embedded inside the e-liquid tank.

[0015] Preferably, the child lock silicone material is silicone, and its shape and size are adapted to the internal space dimensions of the e-liquid tank.

[0016] The e-liquid filling and venting device includes a cross groove, a venting groove, and an e-liquid filling plug. The cross groove and venting groove are respectively opened on the child lock silicone, and the e-liquid filling plug is inserted into the e-liquid tank.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a tobacco cartridge, a silicone child lock for the tobacco cartridge, and a filling and exhaust device for the tobacco cartridge, which has the following beneficial effects:

[0019] 1. This utility model, through the design of the child lock silicone and the cross groove, can bring the following benefits to the overall operation:

[0020] Simplified refilling process and improved operational efficiency: This design achieves automatic opening and closing during refilling through the cross-groove structure of the child lock silicone, eliminating the need for complex disassembly of the cartridge; the refilling device can be directly aligned with the cross-groove for refilling, and the child lock silicone will automatically close after refilling, eliminating the tedious steps of separating the mouthpiece, removing internal components, and reassembling in the traditional refilling method, greatly shortening the refilling time of a single cartridge and providing high convenience.

[0021] 2. This utility model, through its child lock silicone and venting groove design, brings the following benefits to the overall operation:

[0022] Improved exhaust efficiency and solution to filling problems: Compared to the natural exhaust method of the cross-groove gap, the specially designed exhaust groove provides an independent and unobstructed exhaust path for the gas inside the cartridge; during the filling process, the e-liquid enters the e-liquid chamber under the action of the filling pressure, and the internal gas can be quickly and directionally discharged through the exhaust groove, avoiding the accumulation of gas in the chamber and the formation of high pressure. The above-mentioned structured exhaust design can accurately match the filling rate, ensuring that the gas discharge and e-liquid injection are synchronized, eliminating the problem of e-liquid being squeezed into the atomizer core due to poor exhaust;

[0023] Enhanced design synergy and improved overall reliability: The cross groove of the venting channel and the child lock silicone form a complementary function: the cross groove is responsible for opening and closing the filling channel, realizing the child lock and basic sealing functions; the venting channel focuses on efficient venting. The synergy between the two makes the functions of filling, sealing, venting, and preventing accidental contact form an organic whole; the above-mentioned structured design improves the integration and reliability of the e-cigarette cartridge filling system and reduces the compromises and defects caused by a single structure undertaking multiple functions.

[0024] 3. The design of the side strip wall of the e-liquid tank in this utility model can bring the following benefits to the overall operation:

[0025] Improving assembly precision and ensuring structural stability: The side strips provide a clear assembly benchmark and limiting guide for the child lock silicone, allowing it to be precisely embedded into the e-liquid tank along the strips, avoiding offset or skew during assembly. The aforementioned rigid support and limiting function ensures the consistency of the child lock silicone's installation position within the e-liquid tank, reducing individual differences caused by human assembly errors. At the same time, the tight fit between the strips and the child lock silicone enhances the stability of their connection, preventing the child lock silicone from loosening or shifting due to external forces such as vibration or collision during use, ensuring the stable performance of its sealing and venting functions.

[0026] Optimized sealing performance to prevent e-liquid leakage: When the child lock silicone is assembled along the groove, the groove ensures a tight fit with the inner wall of the e-liquid tank, reducing assembly gaps. The supporting role of the groove allows the child lock silicone to maintain a stable shape under pressure, avoiding sealing failure caused by the deformation of the silicone itself. Especially during e-liquid filling and use, the groove limits the deformation range of the child lock silicone, ensuring that it always maintains a good fit with the sealing contact surface of the e-liquid tank, further enhancing the overall sealing performance of the cartridge and effectively preventing e-liquid leakage from assembly gaps.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0041] Example

[0042] Please refer to Figures 1 to 9 As shown:

[0043] A type of e-cigarette cartridge includes a bottom cover 1, an oil-absorbing cotton 2 fixedly connected inside the bottom cover 1, and an oil tank sealing silicone 5 embedded inside the bottom cover 1, with the oil-absorbing cotton 2 located between the bottom cover 1 and the oil tank sealing silicone 5.

[0044] Magnets 3 are symmetrically fixedly connected to the bottom end of the bottom cover 1, and electrodes 4 are symmetrically fixedly connected to the bottom end of the bottom cover 1. The electrodes 4 are located inside the magnets 3. Insulating silicone 6 is provided on the sealing silicone 5 of the oil tank. A bracket 7 is fixedly sleeved on the insulating silicone 6. An inner cotton 8 is provided inside the bracket 7. A heating wire 9 is provided inside the inner cotton 8. An outer cotton 10 is sleeved on the outside of the bracket 7. An atomizing core cover 11 is sleeved on the outer surface of the outer cotton 10. Grooves are equally spaced on the atomizing core cover 11. A sealing ring 12 is embedded in the groove of the atomizing core cover 11. An e-liquid tank 14 is provided on the bottom cover 1. The side walls of the e-liquid tank 14 are symmetrically arranged.

[0045] in:

[0046] Oil-absorbing cotton 2 is used to absorb the oil leaking from inside the e-cigarette cartridge.

[0047] Magnet 3 is used for magnetic attachment to the power supply equipment.

[0048] Electrode 4 is in contact with the power supply terminal of the power supply equipment.

[0049] A further embodiment:

[0050] The e-liquid cartridge has a silicone child lock, including a child lock silicone 13, which is fitted inside the e-liquid tank 14. The child lock silicone 13 is made of silicone and its shape and size are adapted to the internal space size of the e-liquid tank 14.

[0051] in:

[0052] Since the cross groove 1301 is created based on the child lock silicone 13, it is initially closed, thus having the effect of a child lock.

[0053] A further embodiment:

[0054] The e-liquid filling and venting device includes a cross groove 1301, a venting groove 1302, and an e-liquid filling plug 15. The cross groove 1301 and the venting groove 1302 are respectively opened on the child lock silicone 13, and the e-liquid filling plug 15 is inserted into the e-liquid chamber 14.

[0055] in:

[0056] During the filling process, the gas inside the cartridge can be vented through the venting groove 1302 of the child lock silicone 13, which can prevent the e-liquid from leaking out due to the inability to vent during the filling process.

[0057] The side strip of the e-liquid tank 14 can be used as a mounting point. The child lock silicone 13 can be installed into the e-liquid tank 14 along the mounting point. During assembly, the side strip of the e-liquid tank 14 serves as a support and assembly limit.

[0058] Oil filler plug 15 is used to seal the oil filler when not filling or storing.

[0059] Working principle:

[0060] When filling the e-liquid, first install the child lock silicone 13 into the e-liquid tank 14, following the instructions in the appendix. Figure 4 and appendix Figure 5 Simply insert the child lock silicone 13 into the e-liquid tank 14;

[0061] When filling with e-liquid, first open the filling plug 15. At this time, the cross groove 1301 of the child lock silicone 13 is closed, which has the effect of a child lock. Open the cross groove 1301 of the child lock silicone 13 with the filling bottle to start filling. During the filling process, the gas in the e-liquid chamber 14 of the e-liquid cartridge can be vented through the vent groove 1302 of the child lock silicone 13. This can realize the venting action during the filling process and prevent e-liquid from entering the atomizer core cover 11 and causing oil accumulation in the atomizer core, which would lead to oil being sucked in during vaping.

[0062] After filling with oil, pull out the oil bottle, and the cross groove 1301 of the child lock silicone 13 will spring back to its original position under its own elasticity.

[0063] Next, insert the filling plug 15 back into the e-liquid tank 14 to complete the filling operation;

[0064] After completing the above operations, the entire cartridge can be magnetically attracted to the power supply device by the magnet 3 on the bottom cover 1. At this time, the electrode 4 is in contact with the power supply terminal of the power supply device. When in use, the power supply device can indirectly provide current to the heating wire 9 through the electrode 4 for operation. During this process, the other components serve as structural support and safety protection.

[0065] Please refer to the above work process. Figures 1 to 9 .
