Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an oil-core separated electronic cigarette cartridge that can be inhaled in seconds. Background Technology

[0002] In the field of e-cigarette technology, e-liquid cartridges, as one of the core components of e-cigarettes, directly affect the user experience and the product's market competitiveness through their performance and design. With the continuous development of the e-cigarette market, consumers are placing higher demands on the quality and functionality of e-liquid cartridges, especially regarding the storage and use of e-liquid.

[0003] Traditional pre-filled, non-oil-wicking e-liquid cartridges have significant structural design flaws. When not in use, the e-liquid directly soaks the wicking material and heating element. This design exposes the e-liquid to the air for extended periods. Since some components of the e-liquid are volatile, evaporation is inevitable during prolonged contact with air. For example, some flavorings and organic solvents in the e-liquid will gradually evaporate and dissipate, altering the e-liquid's concentration and flavor, affecting the user's taste and aroma experience. Furthermore, as the evaporation process continues, the effective components of the e-liquid decrease, potentially affecting the atomization effect of the heating element and reducing the amount and quality of vapor produced by the e-cigarette.

[0004] Furthermore, prolonged exposure of e-liquid to air can easily lead to spoilage. Oxygen, moisture, and microorganisms in the air may react chemically with or multiply with the e-liquid, accelerating its oxidation and rancidity. Spoiled e-liquid may produce unpleasant odors or irritating smells, and may even pose potential risks to human health, severely reducing the safety and reliability of the product. Therefore, this paper presents an e-cigarette cartridge with a separate oil core that allows for second-level vaping to solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an oil-core separation e-cigarette cartridge that can be drawn in seconds, addressing the shortcomings of existing technologies. This solves the technical problem that existing pre-filled, non-oil-core separation cartridges cause e-liquid to soak the wicking cotton and heating element when not in use, resulting in prolonged exposure of the e-liquid to the air, leading to evaporation and even spoilage.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A second-level inhalation-capable e-cigarette cartridge with separate oil and core includes an oil cup and a heating wire silicone component installed inside the oil cup. The top of the heating wire silicone component and the inner wall of the oil cup form an oil storage chamber for storing e-liquid. The bottom of the oil cup is equipped with a base that can move up and down. The base is equipped with a heating core assembly for heating and atomizing the e-liquid. The heating core assembly passes through the heating wire silicone component and its top is placed inside the oil storage chamber.

[0008] The heating core assembly has an oil-guiding cotton inside for absorbing e-liquid, and several heating core oil inlet holes are formed on the outer wall of the heating core assembly for guiding e-liquid to the oil-guiding cotton; when the base is placed at the bottom point, the heating wire silicone part blocks the heating core oil inlet hole; when the base moves to the top point, the heating core oil inlet hole detaches from the heating wire silicone part and is connected to the oil storage tank.

[0009] The heating wire silicone component is movably installed inside the oil cup. After the oil inlet of the heating core is connected to the oil storage tank, the base pushes the heating wire silicone component to move upward inside the oil cup to compress the space volume inside the oil storage tank.

[0010] Furthermore, a heating wire bracket is provided on the base, and the heating core assembly is mounted on the heating wire bracket.

[0011] Furthermore, the top of the oil cup is formed with a mouthpiece, and the mouthpiece is provided with a smoke outlet channel. The top of the heating core assembly is connected with a smoke guide tube, and the top of the smoke guide tube is movably disposed in the smoke outlet channel.

[0012] Furthermore, a heating wire sealing silicone part is provided between the top of the smoke guide tube and the smoke outlet channel to prevent e-liquid leakage.

[0013] Furthermore, several sealing rings are provided between the inner wall of the oil cup and the outer wall of the base.

[0014] Furthermore, the top of the base is provided with vertically arranged guide posts, which are slidably positioned inside the heating wire silicone component.

[0015] Furthermore, the bottom side wall of the oil cup is formed with a locking hole, and the outer side wall of the base is formed with a buckle that can be inserted into the locking hole.

[0016] Furthermore, the base contains condensation cotton placed directly below the heating element assembly to absorb e-liquid that has not been fully atomized; a pair of electrodes electrically connected to the heating element assembly are installed at the bottom of the base.

[0017] Furthermore, an oil-guiding groove is formed in the middle of the top surface of the silicone heating wire component.

[0018] Furthermore, the top surface of the heating wire silicone part is provided with a ring-shaped heating wire positioning piece for positioning; the inner side wall of the heating wire positioning piece is provided with several protrusions for interference fit with the outer side wall of the bottom of the smoke guide tube.

[0019] The beneficial effects of this invention are as follows: When the base is at its lowest point, the silicone element of the heating wire blocks the oil inlet of the heating core, thus separating the heating core assembly from the e-liquid in the oil storage tank (oil-core separation). This allows the e-liquid to be stored in an independent, sealed oil storage tank, preventing the e-liquid from being exposed to air for a long time, which could lead to evaporation or even spoilage. When installing this cartridge on the e-cigarette, pressing the oil cup applies an upward force to the base, causing the base to move the heating core assembly upward. When the base reaches its highest point, the oil inlet of the heating core disengages from the silicone element of the heating wire, allowing the oil inlet to automatically connect with the oil storage tank. The e-liquid in the oil storage tank automatically flows into the interior of the heating core assembly through the oil inlet for absorption by the wicking cotton, thus supplying oil to the heating core assembly. When the user smokes, the heating core assembly heats and atomizes the e-liquid.

[0020] During the installation of this e-liquid cartridge, once the heating element inlet on the heating element assembly connects with the e-liquid reservoir, the base continues to move upwards to push the heating wire silicone component upwards within the e-liquid cup. This compresses the volume of the e-liquid reservoir, and under pressure, the e-liquid quickly passes through the heating element inlet and soaks into the wicking cotton, allowing the user to immediately inhale and achieve a second-level inhalation effect, thus improving the convenience and user experience of using this e-liquid cartridge.

[0026] The following is a detailed description of an oil-core separation electronic cigarette cartridge of this utility model, which allows for second-level inhalation, with reference to the accompanying drawings.

[0027] like Figure 1-3As shown, an embodiment of the present invention, a second-level vaping e-cigarette cartridge with oil-core separation, includes an oil cup 1 and a heating wire silicone component 2 installed inside the oil cup 1. The top of the heating wire silicone component 2 and the inner wall of the oil cup 1 form an oil storage chamber 3 for storing e-liquid. A movable base 6 is installed at the bottom of the oil cup 1, positioned below the heating wire silicone component 2. A heating wire support 7 is provided on the base 6, and a heating core assembly 8 for heating and atomizing the e-liquid is mounted on the support 7. By setting the heating wire support 7, the heating core assembly 8 can be more stably installed on the base 6, and when the base 6 moves up and down at the bottom of the oil cup 1, it can move up and down along with the heating core assembly 8. The heating core assembly 8 passes through the heating wire silicone component 2 and its top is placed inside the oil storage chamber 3. Because the heating wire silicone component 2 can deform, when the heating core assembly 8 moves up and down, the heating wire silicone component 2 always remains close to the outer wall of the heating core assembly 8, preventing e-liquid in the oil storage chamber 3 from leaking out from the gap between the two.

[0028] Furthermore, the top of the oil cup 1 is formed with a mouthpiece 5, and the mouthpiece 5 has a smoke outlet channel 51. The top of the heating core assembly 8 is connected to a smoke guide tube 81, and the top end of the smoke guide tube 81 is movably disposed within the smoke outlet channel 51, so that the smoke guide tube 81 is connected to the smoke outlet channel 51. When the base 6 moves upward together with the heating core assembly 8, it can drive the smoke guide tube 81 to move upward within the smoke outlet channel 51. When the user smokes through the mouthpiece 5, the heating core assembly 8 is activated to heat the e-liquid to atomize it. The smoke passes through the smoke guide tube 81 and the smoke outlet channel 51 in sequence for the user to inhale. A heating wire sealing silicone element 9 is provided between the top of the smoke guide tube 81 and the smoke outlet channel 51 to prevent e-liquid leakage. Since the top of the smoke guide tube 81 can move within the smoke outlet channel 51, the heating wire sealing silicone element 9 is provided to fill the gap between the top of the smoke guide tube 81 and the smoke outlet channel 51. With the deformation of the heating wire sealing silicone element 9 itself, the gap is filled while the top of the smoke guide tube 81 can still move within the smoke outlet channel 51. Furthermore, e-liquid leakage can be prevented when the cartridge is not in use.

[0029] However, the base 6 moves upward together with the heating core assembly 8 in order to automatically allow the e-liquid in the oil storage tank 3 to flow into the heating core assembly 8. Specifically, the heating core assembly 8 is provided with an oil-guiding cotton 83 for absorbing e-liquid, and a number of heating core oil inlet holes 82 are formed on the outer wall of the heating core assembly 8 to guide the e-liquid to the oil-guiding cotton 83. When the base 6 is at its lowest point, the heating wire silicone part 2 blocks the heating core oil inlet hole 82, separating the heating core assembly 8 from the e-liquid in the oil storage tank 3 (oil-core separation). This allows the e-liquid to be stored in the independently sealed oil storage tank 3, preventing it from being exposed to air for a long time, which could lead to evaporation or even spoilage. When an upward force is applied to the base 6, the base 6 moves the heating core assembly 8 upward. When the base 6 reaches its highest point, the heating core oil inlet hole 82 disengages from the heating wire silicone part 2, allowing the heating core oil inlet hole 82 to connect with the oil storage tank 3. The e-liquid in the oil storage tank 3 automatically flows into the heating core assembly 8 through the heating core oil inlet hole 82 for absorption by the wicking cotton 83. The heating wire (not shown in the figure) inside the wicking cotton 83 heats and atomizes the e-liquid for the user to inhale. In addition, the heating wire (not shown in the figure) inside the wicking cotton 83 and other structures on the heating core assembly 8 are existing technologies and will not be described in detail here.

[0030] Additionally, after the heating element inlet 82 is connected to the oil storage tank 3, to improve the efficiency of e-liquid automatically flowing into the heating element assembly 8, an oil guiding groove 21 is formed in the middle of the top surface of the heating wire silicone part 2. When the heating element inlet 82 is separated from the heating wire silicone part 2, the heating element inlet 82 is placed in the oil guiding groove 21. Under the guiding effect of the oil guiding groove 21, the efficiency of e-liquid in the oil storage tank 3 automatically flowing into the heating element assembly 8 is higher. Several sealing rings 12 are provided between the inner wall of the oil cup 1 and the outer wall of the base 6. The sealing rings 12 also play a role in preventing leakage. When a small amount of e-liquid leaks out from the gap between the heating wire silicone part 2 and the inner wall of the oil cup 1, the sealing rings 12 prevent the e-liquid from leaking out from the gap between the inner wall of the oil cup 1 and the outer wall of the base 6, further improving the leak-proof effect of this e-liquid cartridge. In addition, the top of the base 6 is provided with a vertically arranged guide post 71, and the guide post 71 is slidably disposed inside the heating wire silicone part 2. When the base 6 moves upward with the heating core assembly 8, the guide post 71 guides both of them. In addition, the guide post 71 can also limit the heating wire silicone part 2, preventing the heating core assembly 8 from passing through the heating wire silicone part 2 and causing it to deform, thus preventing the position of the heating wire silicone part 2 from shifting.

[0031] When the cartridge is not in use and the oil core is separated, to prevent the base 6 from moving upwards after accidental contact, a locking hole 10 is formed on the bottom side wall of the oil cup 1, and a buckle 11 is formed on the outer side wall of the base 6 to engage with the locking hole 10. When the base 6 is at the bottom, the buckle 11 engages with the locking hole 10, thus securing the base 6 to the bottom of the oil cup 1. When sufficient force is applied to the base 6, the buckle 11 automatically disengages from the locking hole 10, allowing the base 6 to move upwards on the oil cup 1. Alternatively, a pair of locking holes 10 can be provided, arranged vertically. When the base 6 is at the bottom, the buckle 11 engages with the lower locking hole 10. When the base 6 is at the top, the heating element oil inlet 82 connects to the oil storage tank 3, and the buckle 11 engages with the upper locking hole 10. By providing a pair of vertically arranged locking holes 10, the base 6 can be positioned at either the bottom or top position. When the cartridge needs to be inserted into the e-cigarette, press the oil cup 1 to push the base 6 upward. When the oil cup 1 is pressed down to the point where it can no longer move, it means that the heating element oil inlet 82 is connected to the oil storage tank 3. During the installation of the cartridge, the heating element assembly 8 and the oil storage tank 3 are automatically and quickly connected to achieve a second-level inhalation effect, which improves the convenience and user experience of using the cartridge.

[0032] A condensing cotton 14 is located directly below the heating core assembly 8 within the base 6 to absorb e-liquid that has not been fully atomized. After the heating wire (not shown in the figure) within the wicking cotton 83 heats and atomizes the e-liquid, any remaining e-liquid will flow downwards through the chamber within the heating core assembly 8 (which is used to introduce outside air) and eventually be absorbed by the condensing cotton 14, further preventing e-liquid leakage. A pair of electrodes 13 electrically connected to the heating core assembly 8 are installed at the bottom of the base 6. After the cartridge is inserted into the e-cigarette, the electrodes 13 make contact with the power supply components on the e-cigarette and are electrically connected to supply power to the heating core assembly 8. The electrical connection between the electrodes 13 and the heating core assembly 8 is existing technology and will not be described in detail here.

[0033] In this embodiment, the heating wire silicone component 2 can move upward within the oil cup 1. A ring-shaped heating wire positioning piece 4 is provided on the top surface of the heating wire silicone component 2 for positioning it. When the heating core assembly 8 passes through the heating wire silicone component 2, it also passes through the ring-shaped heating wire positioning piece 4. Furthermore, the inner wall of the heating wire positioning piece 4 is provided with several protrusions for interference fit with the bottom outer wall of the smoke guide tube 81 (from... Figure 3As can be seen from the diagram, under the effect of the interference fit, when no force is applied to the heating wire positioning plate 4, the heating wire positioning plate 4 remains stable, achieving the positioning treatment of the heating wire silicone part 2, thus stabilizing the heating wire silicone part 2 and improving the stability of the oil storage. However, when the base 6 drives the heating core assembly 8 to move upward, the smoke guide tube 81 also moves upward. Because the friction between the outer wall of the heating wire silicone part 2 and the inner wall of the oil cup 1 is greater than the friction between the protrusion of the inner wall of the heating wire positioning plate 4 and the bottom outer wall of the smoke guide tube 81, when the smoke guide tube 81 moves upward, the heating wire silicone part 2 and the heating wire positioning plate 4 will not move upward until they reach the oil inlet hole 82 of the heating core and the oil storage. After the chamber 3 is connected, the top of the base 6 contacts the bottom of the heating wire silicone piece 2. Continuing to push the base 6 upward will push the heating wire silicone piece 2 and the heating wire positioning plate 4 upward together, compressing the volume of the space inside the oil storage chamber 3. Through pressure, the e-liquid is quickly passed through the gap between the protrusions on the inner wall of the heating wire positioning plate 4 and the oil guiding groove 21, and is immersed in the oil guiding cotton 83, providing the heating wire (not shown in the figure) in the oil guiding cotton 83 with the e-liquid required for atomization. By pushing the heating wire silicone piece 2 and the heating wire positioning plate 4 upward together, the e-liquid is quickly immersed in the oil guiding cotton 83, allowing the user to immediately vape and use it, resulting in a better taste and further improving the second-level vaping effect and the user experience.

[0034] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0035] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
