Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, specifically to a leak-proof electronic cigarette. Background Technology

[0002] The connection point between the e-cigarette device and the cartridge (or pod) is a high-risk area for leakage. E-liquid leakage not only wastes consumables but can also corrode the internal circuitry of the device, contaminate hands, and even affect the vaping experience. Existing leak-proof e-cigarettes suffer from the following key technical challenges due to design flaws in their sealing structure and locking mechanism: Poor sealing reliability and high risk of leakage: Traditional electronic cigarettes mostly rely on a single sealing ring to achieve connection and sealing. The sealing ring is affected by long-term immersion in e-liquid and temperature changes, and is prone to aging and deformation, leading to sealing failure. Moreover, most sealing structures do not have active clamping force and rely only on assembly gaps for fit. During use, vibration and collisions can cause the gaps to increase, resulting in a high e-liquid leakage rate. Utility Model Content

[0003] The purpose of this invention is to provide a leak-proof electronic cigarette to solve the problems mentioned in the background art.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0014] Please see Figure 1-5 This utility model provides a technical solution: a leak-proof electronic cigarette, including a cigarette rod 1 and a cigarette holder 25. A mounting platform 2, which is an annular boss, is provided on the upper side of the cigarette rod 1 for positioning the cigarette holder 25. An embedding groove 3 is provided on the upper side of the mounting platform 2, and a lifting groove 4 communicating with the embedding groove 3 is provided inside the mounting platform 2. A sealing plate 5, an annular silicone plate resistant to e-liquid corrosion, is slidably connected to the inside of the embedding groove 3. A lifting plate 6 is glued and fixedly connected to the lower part of the sealing plate 5. The lifting plate 6 is slidably connected to the inside of the lifting groove 4. Several sets of first guide rods 7 are slidably connected to the inner side of the lifting plate 6 along its circumference with uniform clearance. The upper and lower ends of the first guide rods 7 are fixedly connected to the upper and lower inner walls of the lifting groove 4 by injection molding. The lifting plate 6 is guided to slide and avoid deviation. The lifting plate 6 and the lower inner wall of the lifting groove 4 are fixedly connected by adhesive. The first spring 8 is sleeved on the outside of the first guide rod 7. Under normal conditions, it pushes the lifting plate 6 and the sealing plate 5 to move upward to form an active compression seal. The lower part of the pipe 25 is fixedly connected by injection molding with a connecting ring 26. The lower part of the connecting ring 26 is fixedly connected by injection molding with an embedded ring 27. During assembly, the embedded ring 27 is first inserted into the embedded groove 3. Under the dual guidance of the first guide rod 7 and the embedded groove 3, the pipe 25 and the pipe rod 1 are accurately aligned to avoid misalignment and wear between the sealing plate 5 and the first sealing ring 10. When the connecting ring 26 is attached to the mounting platform 2, the initial positioning is completed, which provides a basis for subsequent locking. The upper part of the sealing plate 5 and the lower inner wall of the lifting groove 4 are respectively provided with a first mounting groove 9. The first mounting groove 9 is fixedly connected with a first sealing ring 10 by interference fit. The two sets of first sealing rings 10 enhance the sealing effect between the sealing plate 5 and the embedded ring 27, and between the lifting plate 6 and the lifting groove 4, forming a double leak prevention. Several sets of second mounting grooves 11 are evenly opened on the inner side of the upper side of the smoking rod 1 along the outer periphery of the mounting platform 2. The second mounting groove 11 is fixedly connected with a second sealing ring 12 by interference fit. When the connecting ring 26 of the smoking pipe 25 is attached to the mounting platform 2, the second sealing ring 12 is tightly attached to the lower surface of the connecting ring 26, further blocking the path of e-liquid leakage from the outer periphery. The pipe 1 is fixedly connected to the two sides by injection molding with a connecting box 13. The connecting box 13 is rotatably connected to a threaded rod 14 through a deep groove ball bearing. The outer side of the threaded rod 14 is threadedly connected to a sliding plate 15. The upper two sides of the sliding plate 15 are fixedly connected to two sets of connecting plates 16 by injection molding. The upper part of the connecting plate 16 penetrates the strip hole on the connecting box 13 and is fixedly connected to the mounting box 17 by glue. Rotating the threaded rod 14 can drive the sliding plate 15 to slide up and down along the connecting box 13, and then drive the mounting box 17 to rise and fall through the connecting plate 16. The mounting box 17 has a sliding groove 18 inside. The sliding groove 18 is slidably connected to a pull plate 19 with a clearance fit. The pipe 25 has an insertion hole 28 on both sides corresponding to the position of the hanging plate 20. The mounting box 17 has control grooves 21 on both sides that communicate with the sliding groove 18. A second guide rod 23 is fixedly connected to the inside of the control groove 21 by injection molding. A lug 22 is slidably connected to the outside of the second guide rod 23 with a clearance fit. The lug 22 and the pull plate 19 are fixedly connected by injection molding. The lug 22 and the inner wall of the control groove 21 away from the pipe 25 are fixedly connected by adhesive. The second spring 24 is sleeved on the outside of the second guide rod 23. Under normal conditions, it pushes the pull plate 19 and the hanging plate 20 to move towards the pipe 25, ensuring that the pull plate 19 fits tightly against the inner wall of the locking hole and prevents loosening. A hanging plate 20 is fixedly connected to the side of the pull plate 19 near the pipe 25 by injection molding. Locking holes 29 communicating with the insertion hole 28 are opened inside both sides of the pipe 25. The hanging plate 20 can pass through the insertion hole 28 and slide into the longitudinal section of the locking hole 29 when the mounting box 17 is lowered, thereby locking the pipe 25.

[0015] Working principle: When using this utility model: hold the pipe 25, align the lower embedded ring 27 with the embedded groove 3 of the pipe rod 1 mounting platform 2, and slowly press the pipe down; During the process of inserting the embedded ring 27 into the embedded groove 3, the compression sealing plate 5 and the lifting plate 6 slide downward, the first spring 8 is compressed, and at the same time, the connecting ring 26 gradually fits against the mounting platform 2, and the second sealing ring 12 is in close contact with the lower surface of the connecting ring 26, thus completing the initial sealing and positioning. Press the pipe 25 continuously until the mounting plate 20 aligns with the insertion holes 28 on both sides of the pipe 25. At this time, the second spring 24 pulls the pulling plate 19, causing the mounting plate 20 to automatically pass through the insertion holes 28 and enter the pipe 25. Rotate the threaded rod 14 on the outside of the connecting box 13 clockwise. The threaded rod 14 drives the sliding plate 15 to slide down along the connecting box 13. The connecting plate 16 drives the mounting box 17 to descend synchronously. During the descent of the mounting box 17, the mounting plate 20 moves down along the longitudinal section of the locking hole 29 with the mounting box 17, thereby pulling the pipe 25 closer to the pipe rod 1, so that the connecting ring 26 fits more tightly against the mounting platform 2. The second sealing ring 12 is deformed under pressure, enhancing the outer circumferential seal. At the same time, the first spring 8 always pushes the sealing plate 5 upward to fit tightly against the embedded ring 27. The first sealing ring 10 is compressed to form a double inner seal. When the mounting plate 20 slides to the bottom of the locking hole 29, stop rotating the threaded rod 14 to complete the locking. At this time, the pipe 25 and the pipe rod 1 are securely connected without loosening. During inhalation, the continuous pressure of the first spring 8 ensures that there is no gap between the sealing plate 5 and the embedded ring 27, the first sealing ring 10 prevents e-liquid from leaking inward; the second sealing ring 12 prevents e-liquid from leaking outward, and the double sealing structure effectively prevents leakage. If subjected to slight vibration or impact, the longitudinal section of the mounting plate 20 within the locking hole 29 restricts the vertical movement of the pipe 25. The second spring 24 pulls the mounting plate 20 to fit against the inner wall of the locking hole 29, preventing lateral loosening and ensuring a stable connection. Rotate the threaded rod 14 counterclockwise, and the sliding plate 15 will drive the mounting box 17 to move upward. The hanging plate 20 will rise along the longitudinal section of the locking hole 29 until the hanging plate 20 returns to the horizontal position of the insertion hole 28. Pull the pulling plate 19 outward, and the second spring 24 will be stretched, and the hanging plate 20 will be disengaged from the insertion hole 28, thus releasing the lock. Pull the pipe 25 upwards, the insert ring 27 disengages from the insert groove 3, and the first spring 8 pushes the sealing plate 5 and the lifting plate 6 to reset; after cleaning the residual e-liquid on the surface of the insert groove 3 and the sealing plate 5, a new pipe 25 can be replaced.
