Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a leak-proof electronic cigarette oil storage tank. Background Technology
[0002] Globally, there are increasingly stringent requirements for the quality and user experience of e-cigarette products, which is driving the entire e-cigarette industry to continuously seek technological innovation and breakthroughs.
[0003] However, traditional e-cigarette e-liquid storage tanks have significant defects in structural design and technological application. Their commonly used open structure puts the e-liquid in direct contact with the atomizer coil. This structure faces many risks in actual use scenarios. When the ambient air pressure changes, such as in high-altitude areas or during air travel, the internal air pressure balance of the storage tank is disrupted, which can easily lead to e-liquid leakage. This greatly restricts the healthy and sustainable development of the e-cigarette industry. To overcome these development bottlenecks, technological innovation has become an inevitable trend and key path for the development of the e-cigarette industry. By optimizing the sealing structure of the storage tank, developing innovative structural designs such as multi-level sealing and magnetic sealing, and conducting research on new oil-conducting materials, the contradiction between e-liquid conduction and oil retention can be resolved, and the technology for preventing leakage can be continuously upgraded. However, the mouthpiece and the storage tank are connected by threads, which can easily lead to uneven sealing due to angular misalignment during installation. After long-term use, wear at the interface increases the probability of leakage. Utility Model Content

In this utility model, the e-liquid flows into the atomizer core along the spiral guide groove through capillary action, ensuring that the e-liquid is delivered to the atomizer core evenly and stably. This avoids overflow caused by excessively fast oil delivery and dry burning caused by excessively slow oil delivery, thereby improving atomization efficiency and flavor stability. The condensate collected by the annular baffle is guided to the right-side recovery chamber by the first guide pipe, preventing the condensate from flowing back into the oil storage tank and diluting the e-liquid, effectively reducing the risk of leakage. Furthermore, it can be transferred to the recovery chamber through the second guide pipe to increase the collection capacity and avoid multiple replacements. Attached Figure Description

[0039] Specifically, the air pressure balance pipe 2081 is installed in the middle right side of the oil storage tank body 1. At the same time, a waterproof and breathable membrane 2082 is fixedly connected to the right side of the oil storage tank body 1. In order to ensure that the oil can be effectively prevented from leaking while maintaining the internal pressure balance during oil storage, a sealing gasket 3073 is also fixedly connected to the bottom of the annular baffle 305. The bottom of this sealing gasket 3073 is fixedly connected to the bottom inner side of the oil storage tank body 1, which can further enhance the anti-seepage effect and ensure that the oil will not leak from the bottom. Multiple positioning holes 2074 are opened around the bottom of the mouthpiece interface 2073. The function of these positioning holes 2074 is to ensure that the mouthpiece interface 2073 can be accurately positioned. In order to further enhance the positioning effect, the top of the positioning post 2071 is engaged with the inner wall of the corresponding positioning hole 2074, which can ensure the stability of the mouthpiece interface 2073 and prevent it from shifting during use.
[0040] Working principle: Initial installation is achieved by engaging the positioning pin 2071 with the positioning hole 2074 at the bottom of the mouthpiece interface 2073. A preliminary sealing effect is then achieved through the sealing ring 2072 on the outer wall of the oil storage tank top cover 201. The oil storage tank top cover 201 is then installed on top of the oil storage tank body 1, and a secondary seal is achieved by engaging the sealing frame 4 into the bottom groove of the oil storage tank top cover 201. The slider 205 slides along the outer wall of the sealing frame 4, and the engagement of the positioning pin 206 with the hole 204 and the L-shaped block 202 with the inner groove of the slider 205 enhances the stability and sealing of the installation, effectively resisting daily impacts, reducing structural loosening, extending the service life of the oil storage tank, and improving overall stability. Simultaneously, a waterproof and breathable membrane 2082 covers the air pressure balance pipe 2081 on the right side of the oil storage tank body 1, which can automatically adjust the air pressure inside and outside the oil storage tank, preventing e-liquid leakage due to negative or positive pressure, and ensuring stable operation.
[0041] E-liquid flows into the atomizer core 304 via capillary action along the spiral wicking groove 303, ensuring that the e-liquid is delivered evenly and stably to the atomizer core 304. This avoids overflow caused by excessively fast wicking and dry burning caused by excessively slow wicking, thus improving atomization efficiency and flavor stability. The condensate collected by the annular baffle 305 is guided by the first guide tube 306 to the right-side recovery chamber 3071 for collection, preventing the condensate from flowing back into the e-liquid storage chamber and diluting the e-liquid. This effectively reduces the risk of leakage and can also be transferred to the recovery chamber 3071 through the second guide tube 3072 to increase the collection capacity and avoid multiple replacements.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
