Description

Technical Field

[0001] This invention belongs to the field of atomizing smoking device technology, and particularly relates to a leak-proof and sealed electronic e-cigarette oil tank and a self-sealing oil filling structure. Background Technology

[0002] Currently, the oil tank structure of e-cigarettes on the market is relatively conventional, with most only having a simple oil storage cavity and a straight-through oil filling channel. The sealing method mostly relies on a single rubber stopper or threaded cap to complete the sealing. After long-term use, the seals are prone to aging and deformation, which can easily cause e-liquid to leak and evaporate from the filling port. During carrying and storage, oil stains can easily contaminate the internal and external environment of the device.

[0003] Meanwhile, traditional e-cigarette oil tanks mostly use a natural seepage method for oil supply. The e-liquid relies on its own gravity and the oil guide cotton to naturally seep into the atomizer core. The oil supply flow cannot be synchronized with the user's vaping action. When left still, excessive seepage can easily occur, causing oil splattering and leakage. When vaping, insufficient oil supply can easily occur, resulting in fluctuating vapor production and a poor vaping experience.

[0004] In addition, the existing e-liquid filling structure lacks an automatic closing protection structure, and manual sealing is required after filling, which is cumbersome. Furthermore, the imbalance of air pressure and airflow disturbance inside the chamber will further aggravate the leakage. The conventional e-liquid chamber lacks a quantitative buffer and guiding structure, which cannot achieve stable delivery of e-liquid. There is still much room for improvement in overall stability and user experience. Summary of the Invention

[0005] The purpose of this invention is to provide a leak-proof and sealed e-cigarette oil tank and a self-sealing oil filling structure. This leak-proof and sealed e-cigarette oil tank and self-sealing oil filling structure achieves automatic sealing of the oil filling port to prevent oil leakage through a torsion spring self-sealing structure. It utilizes the suction airflow to drive the spiral blades to drive the internal components to supply oil in a coordinated manner. The oil supply and suction action are synchronized and matched. The whole structure is a purely mechanical structure with good sealing performance, uniform and stable oil supply, and convenient assembly and production.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A leak-proof, sealed electronic e-cigarette oil tank and a self-sealing oil filling structure include an oil tank, a plug-in end, and a connecting end. Two connecting ends are integrally fixed to both ends of the oil tank. One connecting end is used for oil filling and communicates internally with the oil tank. The other connecting end is used for plugging into and connecting to a cigarette mouthpiece. The plug-in end is fixed to the end of the oil tank away from the cigarette mouthpiece and surrounds the connecting end used for oil filling. An oil filling port is provided at the top of the oil tank. An inner sealing plate is provided inside the oil tank. A fixing column is also provided inside the oil tank, and an oil supply component is rotatably connected to the outside of the fixing column. An oil seepage plate is provided near the bottom of the oil tank, and the end of the oil supply component away from the fixing column rotates inside the oil seepage plate. The oil supply component is located between the inner sealing plate and the oil seepage plate.

[0007] As a preferred embodiment of the present invention, an annular track is integrally fixed on the oil-permeable plate.

[0008] As a preferred embodiment of the present invention, the oil supply component includes a sleeve rotatably connected to the outside of the fixed column. The end of the sleeve away from the fixed column is integrally provided with a rotating cylinder. The rotating cylinder is hollow inside. A connecting shaft is fixed inside the rotating cylinder. The end of the connecting shaft away from the rotating cylinder extends out along the bottom of the connecting end for oil injection. The extended end of the connecting shaft is provided with a spiral blade. The spiral blade is fixed on the side of the connecting shaft and is provided at equal angles along the circumference of the connecting shaft. The end of the rotating cylinder away from the sleeve rotates inside the annular track.

[0009] As a preferred embodiment of the present invention, the oil injection component further includes cotton blocks bonded and fixed to the inner wall of the oil tank. Several cotton blocks are arranged at equal angles along the circumferential direction of the oil tank, and the cotton blocks are hemispherical.

[0010] As a preferred embodiment of the present invention, an oil inlet block is fixed on the side of the rotating cylinder. The oil inlet block is hemispherical and is arranged at equal angles along the circumference of the rotating cylinder. The oil inlet block and the cotton block are arranged intersectingly, and each oil inlet block is connected to the inside of the rotating cylinder.

[0011] As a preferred embodiment of the present invention, the oil inlet block is provided with through holes on its side, and a plurality of through holes are provided, which are evenly distributed on the surface of the oil inlet block.

[0012] The present invention also provides a self-sealing oil injection structure, which is installed inside an oil tank and includes a sealing plate fixed near the top of the oil tank. The sealing plate has a slot communicating with the oil injection port. At the bottom of the slot is an oil injection hollow column fixed to the sealing plate. The bottom of the oil injection hollow column is fixedly inserted through the inner sealing plate.

[0013] As a preferred embodiment of the present invention, a partition rib is fixed inside the oil injection hollow column. The partition rib is provided with a through groove. A pressure groove is provided on the side of the through groove facing the inner sealing plate. A sealing block is attached to the pressure groove. The side of the sealing block is rotatably connected to the inner wall of the oil injection hollow column.

[0014] As a preferred embodiment of the present invention, a fixing seat is fixed on the inner wall of the oil injection hollow column. The fixing seats are symmetrically arranged, and a rotating shaft is rotatably connected between the two fixing seats. The side of the rotating shaft is fixed to the side of the sealing block, and a torsion spring is sleeved on the outside of the rotating shaft. The end of the torsion spring is fixed to the side of the fixing seat.

[0015] In summary, the beneficial technical effects of the present invention are as follows: 1. This invention employs a torsion spring combined with sealing blocks to form a self-sealing e-liquid filling structure. Under normal conditions, it can automatically seal the e-liquid flow channel without manual sealing. After e-liquid filling, it can quickly reset and close, effectively preventing e-liquid leakage from the tank and isolating external dust and moisture from entering and contaminating the e-liquid. Combined with the multi-layered sealing structure inside the tank, it can effectively balance the airflow environment within the tank, avoiding e-liquid spillage and leakage problems caused by temperature differences, shaking, and bumps, significantly improving the overall sealing reliability of the tank.

[0016] 2. This invention features spiral blades on the outer side of the extended connecting shaft. The blades rotate based on the airflow generated during inhalation, which in turn drives the entire e-liquid supply assembly to operate synchronously. This causes the e-liquid inlet block and the e-liquid storage cotton block inside the chamber to press against each other, guiding the e-liquid and achieving simultaneous e-liquid supply during inhalation and automatic slow-stopping of e-liquid supply when inhalation stops. The entire process is driven purely by mechanical airflow, requiring no additional electronic control or manual adjustment. The e-liquid supply rhythm is highly matched to the inhalation action, preventing e-liquid accumulation and leakage during stagnation and ensuring a sufficient and even supply of e-liquid during inhalation, effectively improving the smoke output and flavor.

[0017] 3. This invention adopts an integrated splicing and molding structure design. The oil tank has an integrated oil filling dock and a mouthpiece insertion dock at both ends. The external insertion dock allows for quick positioning and assembly. The overall component arrangement is neat, the injection molding process is simple, and it is easy to mass-produce. The internal oil supply component relies on a coaxial limiting track for rotational limiting, ensuring smooth operation and preventing jamming. The hemispherical oil guiding structure is wear-resistant and durable, reducing the likelihood of clogging and failure. The overall assembly and maintenance are simple, and it is compatible with various specifications of electronic cigarette devices, offering a wide range of applications and a longer service life.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-4 The present invention provides a technical solution: This embodiment discloses a leak-proof and sealed e-liquid tank 1 and a self-sealing e-liquid filling structure, which is compatible with conventional integrated e-cigarette assembly. The overall structure is compact and easy to assemble. Relying on the internal linkage e-liquid supply component and the automatic closing sealing component, it can not only smoothly complete the e-liquid replenishment and quantitative e-liquid delivery, but also achieve automatic sealing of the port after the e-liquid filling is completed, effectively preventing e-liquid leakage, evaporation and external impurities from entering the e-liquid tank 1. At the same time, it can achieve uniform e-liquid supply to the atomizing component, and has stronger stability in use.

[0023] The leak-proof sealed e-cigarette oil tank 1 mainly includes the oil tank 1 body, the plug-in end 2, and two sets of connecting ends 3. The two sets of connecting ends 3 are integrally formed and fixedly installed at the upper and lower ends of the oil tank 1, respectively. The connecting end 3 at the upper end of the oil tank 1 serves as the oil filling connecting end 3, and its internal cavity is interconnected with the oil storage cavity of the oil tank 1 for connecting with external oil filling devices to complete the oil filling operation. The connecting end 3 at the lower end of the oil tank 1 serves as the mouthpiece docking end, which can be directly plugged into the e-cigarette mouthpiece to achieve smoke exhaust. The plug-in end 2 is fixedly installed at the end of the oil tank 1 away from the mouthpiece, and the plug-in end 2 completely surrounds the outside of the oil filling connecting end 3. On the one hand, it can provide physical protection for the oil filling connecting end 3, and on the other hand, it can complete the positioning and limiting during the overall assembly, improving the fit of the whole device.

[0024] A through-type oil inlet 4 is provided at the top of the oil tank 1, serving as the main channel for e-liquid injection. An inner sealing plate 15 is horizontally fixedly installed inside the oil tank 1, separating the upper and middle spaces of the oil tank 1's inner cavity and providing initial isolation and leakage prevention. A fixed column 6 is vertically fixedly installed at the center of the oil tank 1's inner cavity, and an oil supply component is rotatably mounted on the outer wall of the fixed column 6, allowing the oil supply component to rotate circumferentially. An oil seepage plate 7 is horizontally fixedly installed near the bottom of the oil tank 1's inner cavity, with the end of the oil supply component away from the fixed column 6 rotatably embedded inside the oil seepage plate 7, thus confining the entire oil supply component within the oil storage cavity area between the inner sealing plate 15 and the oil seepage plate 7, fixing its range of motion and preventing any displacement or shaking.

[0025] The upper end face of the oil seepage plate 7 is integrally formed with a ring track. The ring track is coaxially arranged with the fixed column 6, providing precise sliding limit for the bottom rotating end of the oil supply component, ensuring that the oil supply component rotates smoothly and without jamming or deviation.

[0026] The oil supply component includes a sleeve 9 and a rotating cylinder 10. The sleeve 9 is rotatably fitted onto the outer wall of the fixed column 6. The end of the sleeve 9 away from the fixed column 6 is integrally formed and connected to the rotating cylinder 10. The rotating cylinder 10 adopts a hollow cavity structure design. A connecting shaft 11 is fixedly connected to the center of the inner cavity of the rotating cylinder 10. The end of the connecting shaft 11 away from the rotating cylinder 10 extends downward through the bottom of the oil injection connecting end 3 and outward. Several spiral blades 25 are fixedly arranged on the outer wall of the outwardly extending connecting shaft 11. The spiral blades 25 are evenly arranged and fixed at equal angles along the circumference of the connecting shaft 11. The spiral blades 25 are arranged corresponding to the flue gas flow channel and can generate rotational driving force under the action of the suction airflow. The bottom end of the rotating cylinder 10 away from the sleeve 9 is slidably and rotatably assembled inside the annular track 8 on the surface of the oil seepage plate 7. The annular track 8 is used to complete radial positioning and further improve rotational stability.

[0027] Several cotton blocks 12 are evenly adhered and fixed on the inner wall of the oil tank 1. All cotton blocks 12 are arranged at equal angles along the circumference of the inner wall of the oil tank 1. The cotton blocks 12 are set as a hemispherical structure. The cotton blocks 12 have good oil adsorption and conduction performance, which can adsorb the e-liquid stored inside the oil tank 1, prevent the e-liquid from shaking and splashing randomly inside the tank, and at the same time realize the temporary storage of e-liquid.

[0028] Several oil inlet blocks 13 are fixedly installed on the outer wall of the rotating cylinder 10. The oil inlet blocks 13 are also evenly distributed at equal angles along the circumference of the rotating cylinder 10. The oil inlet blocks 13 also adopt a hemispherical structure design. The oil inlet blocks 13 and the cotton blocks 12 on the inner wall of the oil tank 1 are arranged in an alternating manner. The two do not interfere with each other and can cooperate with each other to complete the oil guiding operation. The internal cavity of each oil inlet block 13 is connected to the hollow structure of the rotating cylinder 10, ensuring that the e-liquid can flow smoothly into the oil supply component.

[0029] Each oil inlet block 13 has several evenly distributed through holes 14 on its outer surface. The liquid e-liquid stored inside the oil tank 1 can seep into the oil inlet block 13 through each through hole 14, and then flow into the inner cavity of the rotating cylinder 10 through the oil inlet block 13 to complete the collection and transportation of e-liquid. The porous structure can improve the oil intake efficiency and at the same time, it can simply intercept large particles of impurities to prevent impurities from entering the oil supply channel and causing blockage.

[0030] This invention also discloses a self-sealing oil filling structure adapted for use in the oil tank 1. This self-sealing oil filling structure is fixedly assembled within the oil tank 1 near the top and mainly consists of a sealing plate 15, an oil-filling hollow column 17, and an automatic sealing assembly. The sealing plate 15 is horizontally fixed to the upper part of the oil tank 1. A groove 16 is provided on the surface of the sealing plate 15, directly communicating with the top oil filling port 4. An oil-filling hollow column 17 is vertically fixed at the bottom of the groove 16. The bottom end of the oil-filling hollow column 17 is vertically inserted through and fixed onto the surface of the inner sealing plate 15, allowing the e-liquid injected from the oil filling port 4 to flow along the groove 16 into the interior of the oil-filling hollow column 17, and then downwards into the oil storage cavity of the oil tank 1 to complete oil storage.

[0031] A partition rib 18 is integrally formed in the internal cavity of the oil-filling hollow column 17. The partition rib 18 divides the interior of the oil-filling hollow column 17 into a flow channel. A through-flow hole 14 is opened on the plate body of the partition rib 18. A concave pressure groove 20 is opened on the side of the partition rib 18 facing the inner sealing plate 15. A sealing block 21 is attached to the inside of the pressure groove 20. The sealing block 21 can be flipped open and closed. The side edge of the sealing block 21 is pivotally hinged to the inner wall of the oil-filling hollow column 17, and can swing with the hinge position as the fulcrum.

[0032] Two sets of fixing seats 22 are symmetrically fixed on the inner wall of the oil-filling hollow column 17. The two sets of fixing seats 22 are arranged in a left-right correspondence. A horizontally arranged connecting shaft 11 is rotatably assembled between the two sets of fixing seats 22. The side wall of the connecting shaft 11 is fixedly connected to the side of the sealing block 21, thereby realizing the hinged flipping of the sealing block 21. A torsion spring 24 is sleeved on the outer wall of the connecting shaft 11. The two ends of the torsion spring 24 are respectively fixed on the side walls of the fixing seats 22 on both sides. Under normal conditions, the torsion spring 24 is in an energy storage state. Relying on the elastic torque of the torsion spring 24, it continuously drives the sealing block 21 to adhere and press tightly inside the pressure groove 20, completely sealing the through hole 14 on the partition rib plate 18. At this time, the internal channel of the oil-filling hollow column 17 is in a closed and sealed state, which can completely prevent the e-liquid inside the oil tank 1 from leaking out from the oil filling port 4. At the same time, it can also prevent external dust, moisture and other impurities from entering the oil tank 1 through the oil filling port 4.

[0033] During the actual oil filling operation, the external oil filling device is inserted into the oil filling port 4 at the top of the oil tank 1. The end of the oil filling device pushes the sealing block 21 downward, overcoming the elastic torque of the torsion spring 24, causing the sealing block 21 to flip and shift around the connecting shaft 11, so that the sealing block 21 is separated from the inside of the pressure groove 20, and the through hole 14 on the partition rib plate 18 is opened smoothly. At this time, the e-liquid can flow smoothly into the oil storage cavity of the oil tank 1 along the internal channel of the oil filling hollow column 17. When the oil filling operation is completed, the oil filling device is pulled out directly. The external pushing force disappears instantly, the torsion spring 24 quickly releases its elastic potential energy, pulls the connecting shaft 11 in the opposite direction to rotate, and then drives the sealing block 21 to quickly reset and re-close tightly in the pressure groove 20 position, automatically completing the sealing and closure of the oil filling channel. There is no need for manual sealing. The sealing response speed is fast and the sealing tightness is high.

[0034] During normal use of the electronic cigarette, when the user inhales and exhales, a directional airflow is formed in the smoke circulation channel. The airflow directly impacts the spiral blades 25 fixed on the outside of the connecting shaft 11. The spiral blades 25 are driven to rotate by the airflow thrust, which in turn drives the entire connecting shaft 11 to rotate synchronously in the circumferential direction. The rotation of the connecting shaft 11 synchronously drives the rotating cylinder 10 at the top to rotate as well. During the rotation of the rotating cylinder 10, the oil inlet blocks 13 distributed on its outer side come into contact with and squeeze the hemispherical cotton blocks 12 with e-liquid adsorbed on the inner wall of the oil tank 1. With the help of the squeezing action, the e-liquid adsorbed inside the cotton blocks 12 is quickly discharged. The e-liquid enters the rotating cylinder 10 through the through holes 14 on the surface of the oil inlet blocks 13, and is then uniformly transported to the atomization position at the bottom of the electronic cigarette for atomization.

[0035] The system automatically drives the e-liquid supply mechanism by relying on the airflow generated by the inhaled smoke, achieving a synchronized effect of supplying e-liquid as you inhale and slowing down the supply when you stop inhaling. There is no need for manual adjustment. The e-liquid supply rhythm is completely synchronized with the inhalation action. This can avoid the problem of continuous oil seepage and leakage when the system is stationary, and ensure that the e-liquid supply is sufficient and even during the inhalation process. It effectively prevents problems such as oil splattering caused by excessive supply and a bitter taste or unstable smoke output caused by insufficient supply.

[0036] The connecting ends 3 at both ends of the oil tank 1 complete the oil filling docking and the mouthpiece docking respectively, and the outer plug-in end 2 completes the overall assembly positioning. The assembly structure of the whole machine is simple and easy to disassemble and maintain. The overall structure relies on airflow to drive the rotation oil supply and a torsion spring 24-type automatic sealing structure. There is no need to add electronic control components. The pure mechanical structure has strong stability, low production cost, and is not prone to failure such as sealing failure and oil supply jamming after long-term use. It is suitable for mass production and assembly of various specifications of electronic cigarettes, and has extremely strong practicality and versatility.
