Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electromagnetic adaptive oil core separation electronic cigarette. Background Technology

[0002] In recent years, with the rapid development of e-cigarette technology, atomizer structure design has become a core research direction for improving user experience. Traditional e-cigarettes generally adopt an open structure where the e-liquid reservoir and the atomizer coil are directly connected. E-liquid is continuously supplied to the atomizer coil through gravity or capillary action. However, this design has significant drawbacks: when not in use, the atomizer coil is prone to leakage due to prolonged immersion in e-liquid, and oversaturated wicking cotton can cause the coil to burn. During use, the mechanical wicking structure cannot dynamically adjust the e-liquid supply according to the user's vaping intensity, which can easily lead to excessive e-liquid supply causing splattering or insufficient e-liquid supply causing dry burning, seriously affecting atomization efficiency and flavor consistency.

[0003] While some existing technologies attempt to achieve oil-wick separation through physical isolation, their mechanical valves exhibit significant lag in response, making precise displacement control impossible. Furthermore, during short-duration suction, the valve opening amplitude and suction negative pressure do not correlate linearly, resulting in insufficient precision in oil supply regulation. In addition, purely mechanical sensing solutions require extremely high assembly precision, and prolonged use can lead to seal failure due to component aging, thus exacerbating the risk of oil leakage.

[0004] Furthermore, current mainstream e-cigarette products generally lack the ability to adapt to users' vaping habits. When users take a shallow puff, traditional atomizers still supply e-liquid at a fixed power, resulting in excess e-liquid failing to atomize fully and condensing in the airway, causing e-liquid waste. On the other hand, during deep puffs, insufficient e-liquid supply may cause localized dry burning of the atomizer coil, producing harmful substances. Therefore, this paper presents an electromagnetically adaptive coil-separation e-cigarette to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an electromagnetic adaptive oil-core separation electronic cigarette to address the shortcomings of existing technologies, thereby solving the technical problems that existing electronic cigarettes cannot achieve oil-core separation and cannot accurately control the amount of oil entering the cigarette based on the magnitude of the negative pressure of the airflow during inhalation.

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

[0007] An electromagnetic adaptive e-cigarette with a separate e-liquid core includes an e-liquid cup and a base installed at the bottom of the e-liquid cup. The top of the base and the inner wall of the e-liquid cup together form an e-liquid storage chamber for storing e-liquid. A cavity is formed inside the base. A lower seal is installed at the bottom of the cavity and an upper seal is installed at the top of the cavity. The upper surface of the lower seal, the lower surface of the upper seal, and the inner wall of the cavity together form an e-liquid guiding cavity. An atomizing core assembly is installed inside the e-liquid guiding cavity.

[0008] The top of the base is formed with an oil inlet hole, and the inner wall of the oil inlet hole is provided with a connecting hole that connects to the oil guide cavity. A valve block that can move up and down along the hole is adapted to be installed in the oil inlet hole. Under normal conditions, the valve block blocks the top port of the oil inlet hole.

[0009] The lower seal is formed with a guide groove, and a push rod that can slide up and down is provided in the guide groove. The top of the push rod extends into the oil inlet hole and is fixed to the valve block. An electromagnet is provided below the push rod to generate an electromagnetic force to attract the push rod downward when energized. The valve block moves downward, and the throttling gap formed between its top surface and the opening of the connecting hole gradually expands.

[0010] It also includes a power supply component for detecting the magnitude of the airflow negative pressure and supplying power to the electromagnet. The power supply component adjusts the voltage output to the electromagnet according to the magnitude of the airflow negative pressure.

[0011] Furthermore, a reset component is provided between the bottom surface of the valve block and the bottom of the oil inlet hole for applying an upward pushing force to reset the valve block.

[0012] Furthermore, the reset component includes a lower connecting part disposed at the bottom of the oil inlet hole and an upper connecting part disposed on the bottom surface of the valve block. A spring for applying an upward pushing force to the valve block is provided between the upper connecting part and the lower connecting part, and the top end of the spring is connected to the upper connecting part and the bottom end is connected to the lower connecting part. A limiting pin is provided on the top surface of the base for blocking the reset valve block to block the top port of the oil inlet hole.

[0013] Furthermore, a lower housing is fixedly mounted at the bottom of the oil cup. The power supply components include a battery bracket housed within the lower housing, a circuit board mounted on the battery bracket, and a battery electrically connected to the circuit board. The atomizer core assembly is electrically connected to the circuit board, and an electromagnet is mounted within the battery bracket and electrically connected to the circuit board. A charging port for charging the battery is mounted on the circuit board. An air intake hole is formed at the bottom of the lower housing to allow outside air to enter the atomizer core assembly. A microphone for detecting negative airflow pressure is also provided inside the battery bracket.

[0014] Furthermore, the top of the battery holder is formed with an upwardly extending extension, the top surface of which is formed with a groove, and the groove is filled with oil-absorbing cotton for absorbing e-liquid that has not been fully atomized; the bottom surface of the lower seal is formed with a mounting groove for the extension to be inserted, and the top of the mounting groove is provided with an air duct that communicates with the atomizing core assembly.

[0015] Furthermore, the outer side of the atomizer core assembly is formed with oil guide holes for guiding the e-liquid in the oil guide cavity to its interior.

[0016] Furthermore, both the upper and lower seals are made of silicone, and the sidewalls of both the upper and lower seals are interference-fitted with the inner sidewall of the cavity.

[0017] Furthermore, a sealing sleeve is provided on the bottom contact surface between the base and the oil cup to prevent e-liquid leakage.

[0018] Furthermore, the top of the oil cup is formed with a mouthpiece, inside which is a vertically arranged smoke guide tube with its top end connected to the mouthpiece. The bottom end of the smoke guide tube passes through the upper seal and is inserted and connected to the top of the atomizing core assembly.

[0019] Furthermore, the base is equipped with an oil injection hole that communicates with the oil storage tank, and the oil injection hole is filled with an oil injection plug for plugging it.

[0020] The beneficial effects of this invention are as follows: This electronic cigarette places the atomizing core assembly inside the oil guiding cavity and uses a valve block to block the top port of the oil inlet, preventing the e-liquid in the oil storage tank from flowing into the oil guiding cavity through the connecting hole, thus achieving oil-core separation. When the electromagnet is energized, a downward magnetic force is generated, which attracts the push rod to move downward in the guide groove, moving the valve block downward as well. This causes the throttling gap formed between the top surface of the valve block and the opening of the connecting hole to gradually widen. The e-liquid in the oil storage tank passes sequentially through the oil inlet, the throttling gap, and the connecting hole before entering the oil guiding cavity and finally flowing into the atomizing core assembly for heating and atomization. When the electromagnet is de-energized, the valve block returns to its original position. During the return process, the throttling gap gradually narrows until the valve block completely blocks the top port of the oil inlet again. The downward movement distance of the valve block is controlled by magnetic attraction, achieving dynamic regulation of the amount of e-liquid entering the oil guiding cavity.

[0021] In addition, the power supply component can be used to detect the negative pressure of the airflow. When the user inhales, the power supply component detects different airflow negative pressures and adjusts the voltage supplied to the electromagnet according to the different airflow negative pressures, thereby precisely controlling the downward displacement distance of the push rod. When the airflow negative pressure increases during inhalation, the voltage output to the electromagnet increases, the downward displacement distance of the push rod increases, and the throttling gap formed between the top surface of the valve block and the orifice also increases, increasing the e-liquid intake. Conversely, when the airflow negative pressure decreases during inhalation, the voltage output to the electromagnet decreases, and the throttling gap also decreases, reducing the e-liquid intake. This allows for precise control of the e-liquid intake based on the airflow negative pressure during inhalation, adapting to different customers' vaping habits, preventing excessive e-liquid from entering the atomizer core assembly and causing e-liquid splattering during inhalation, thus improving the user experience.

[0028] The following is a detailed description of an electromagnetic adaptive oil core separation electronic cigarette according to the present invention, with reference to the accompanying drawings.

[0029] like Figure 1-4 As shown, an embodiment of the present invention, an electromagnetic adaptive oil core separation electronic cigarette, includes an oil cup 1 and a base 3 installed at the bottom of the oil cup 1. The top of the base 3 and the inner wall of the oil cup 1 together form an oil storage chamber 4 for storing e-liquid. The base 3 is snapped into the bottom of the oil cup 1, and a sealing sleeve 5 is provided on the contact surface between the bottom of the base 3 and the oil cup 1 to prevent e-liquid leakage. By filling the gap between the base 3 and the oil cup 1 with the sealing sleeve 5, the e-liquid in the oil storage chamber 4 is prevented from leaking out from the gap between the two, thereby improving the sealing performance of the oil storage chamber 4.

[0030] The base 3 has a cavity, with a lower seal 6 installed at the bottom and an upper seal 8 installed at the top, which is placed inside the oil storage tank 4. The upper surface of the lower seal 6, the lower surface of the upper seal 8, and the inner wall of the cavity together form an oil guiding cavity 7, which can be filled with 1ml of e-liquid. Both the upper seal 8 and the lower seal 6 are made of silicone. Therefore, when the upper seal 8 and the lower seal 6 are installed at the bottom of the cavity, the side walls of the upper seal 8 and the lower seal 6 are press-fitted with the inner wall of the cavity to improve the sealing performance of the oil guiding cavity 7.

[0031] The wicking chamber 7 houses an atomizing core assembly 9 for adding e-liquid to the atomizer. The outer side of the atomizing core assembly 9 has wicking holes 10 for guiding the e-liquid within the wicking chamber 7 to its interior. The atomizing core assembly 9 is existing technology, containing a reservoir cotton and a heating element (not shown in the figure) located inside the reservoir cotton. The e-liquid within the wicking chamber 7 flows through the wicking holes 10 to the interior of the atomizing core assembly 9 for absorption by the reservoir cotton, continuously supplying e-liquid to the heating element. This activates the heating element to heat the e-liquid and generate vapor for the user to inhale. To facilitate the airflow carrying the generated vapor out of the atomizing core assembly 9, a mouthpiece 101 is formed at the top of the oil cup 1. Inside this mouthpiece 101 is a vertically arranged smoke guide tube 11, the top of which communicates with the mouthpiece 101. The bottom end of the smoke guide tube 11 passes through the upper sealing member 8 and is inserted into the top of the atomizing core assembly 9. When a user inhales through the mouthpiece 101, air enters the atomizing core assembly 9. At this time, the atomizing core assembly 9 operates, heating the e-liquid to produce smoke. Subsequently, the air carries the produced smoke out from inside the atomizing core assembly 9 and guides it through the smoke guide tube 11 for the user to inhale.

[0032] When the bottom end of the smoke guide tube 11 passes through the upper seal 8 and is inserted into the top of the atomizer core assembly 9, the upper seal 8 deforms to ensure an interference fit between the outer wall of the smoke guide tube 11 and the upper seal 8, preventing e-liquid in the e-liquid reservoir 4 from entering the atomizer core assembly 9 from the top. Alternatively, the top of the upper seal 8 can be used to fill the gap between the bottom end of the smoke guide tube 11 and the top of the atomizer core assembly 9, which not only improves the seal between the smoke guide tube 11 and the atomizer core assembly 9, preventing air leakage during inhalation, but also prevents e-liquid in the e-liquid reservoir 4 from entering the atomizer core assembly 9.

[0033] When the user uses this electronic cigarette, in order to achieve a continuous supply of oil to the atomizing core assembly 9, an oil inlet hole 12 is formed on the top of the base 3 (e.g., ...). Figure 4 As shown, the inner wall of the oil inlet 12 is provided with a connecting hole 13 that connects to the oil guiding cavity 7. A valve block 15 that can move up and down along the hole is adapted to be installed in the oil inlet 12. The valve block 15 can block the top port of the oil inlet 12. After the valve block 15 blocks the top port of the oil inlet 12, the e-liquid in the oil storage tank 4 cannot flow into the oil guiding cavity 7 through the connecting hole 13. When the valve block 15 is continuously moved downward under the action of external force, the throttling gap formed between its top surface and the opening of the connecting hole 13 gradually expands. The e-liquid in the oil storage tank 4 passes through the oil inlet 12, the throttling gap and the connecting hole 13 in sequence, and then enters the oil guiding cavity 7, and finally enters the atomizing core assembly 9 through the oil guiding hole 10. Conversely, during the process of the valve block 15 resetting upward, the throttling gap gradually shrinks until the valve block 15 blocks the top port of the oil inlet 12 again and completely closes it. By controlling the downward movement distance of the valve block 15, the amount of e-liquid entering the oil guiding cavity 7 can be dynamically controlled.

[0034] In order to control the valve block 15 to move up and down automatically in the oil inlet hole 12, the lower seal 6 is formed with a guide groove 141. A push rod 14 that can slide up and down is provided in the guide groove 141. The top end of the push rod 14 extends into the oil inlet hole 12 and is fixedly connected to the valve block 15. A lower housing 2 is fixedly mounted at the bottom of the oil cup 1. An electromagnet 26 is provided in the lower housing 2 to generate an electromagnetic force to attract the push rod 14 downward when energized. A reset component is provided between the bottom surface of the valve block 15 and the bottom of the oil inlet hole 12 to apply an upward pushing force to reset the valve block 15. The push rod 14 is a magnetic metal part. When the electromagnet 26 is energized, it generates a downward electromagnetic force, which attracts the push rod 14 to move downward in the guide groove 141. This causes the valve block 15 to move downward together, gradually widening the throttling gap formed between the top surface of the valve block 15 and the orifice of the connecting hole 13, and gradually increasing the amount of oil entering the oil guide cavity 7. When the electromagnet 26 is de-energized, the reset component applies an upward pushing force to the valve block 15, pushing the valve block 15 upward to reset and re-block the top port of the oil inlet hole 12.

[0035] Furthermore, the reset component includes a lower connecting part 16 located at the bottom of the oil inlet hole 12 and an upper connecting part 17 located on the bottom surface of the valve block 15. A spring 18 is provided between the upper connecting part 17 and the lower connecting part 16 to apply an upward pushing force to the valve block 15. The top end of the spring 18 is connected to the upper connecting part 17, and the bottom end is connected to the lower connecting part 16. A limiting pin 19 is provided on the top surface of the base 3 to block the reset valve block 15 and block the top port of the oil inlet hole 12. When the electromagnet 26 attracts the valve block 15 and moves downward, the spring 18 is compressed. After the attraction of the valve block 15 stops, the valve block 15 is pushed upward and reset under the action of the spring 18. After being blocked by the limiting pin 19, the valve block 15 just blocks the top port of the oil inlet hole 12.

[0036] The lower housing 2 houses a power supply component for supplying power to the electromagnet 26 and the atomizing core assembly 9 and controlling their operation. This power supply component also detects the magnitude of the airflow negative pressure and adjusts the voltage output to the electromagnet 26 accordingly. Specifically, the power supply component includes a battery holder 20 housed within the lower housing 2. The battery holder 20 houses a circuit board 21 and a battery 22. The battery 22 is electrically connected to the circuit board 21 via nickel strip spot welding. The atomizing core assembly 9 is electrically connected to the circuit board 21. A charging port 23 for charging the battery 22 is mounted on the circuit board 21. The battery 22 can be charged by plugging a charging cable into the charging port 23. The bottom of the lower housing 2 has an air intake 24 for allowing outside air to enter the atomizing core assembly 9. The battery holder 20 also houses a microphone 25 for detecting airflow negative pressure; the microphone 25 is an airflow sensor. When the user inhales, outside air enters the atomizing core assembly 9 through the air inlet 24. After the air is detected by the microphone 25, the atomizing core assembly 9 is controlled to operate. The microphone 25, battery 22, circuit board 21, charging port 23 and air inlet 24 are all existing technologies and will not be described in detail here.

[0037] In addition, the circuit board 21 is electrically connected to the electromagnet 26 and provides a driving power to the electromagnet 26 through an independent power supply circuit. When the user inhales, the microphone 25 can sense different airflow negative pressures and adjust the voltage supplied to the electromagnet 26 according to the different airflow negative pressures, thereby precisely controlling the downward displacement distance of the push rod 14 (accuracy ±0.1mm). When the airflow negative pressure increases, the voltage output to the electromagnet 26 increases, the downward displacement distance of the push rod 14 increases, and the throttling gap formed between the top surface of the valve block 15 and the orifice of the connecting hole 13 also increases, increasing the oil intake. Conversely, when the airflow negative pressure decreases, the voltage output to the electromagnet decreases, the throttling gap also decreases, and the oil intake decreases. This achieves precise control of the oil intake based on the airflow negative pressure when the user inhales, adapting to meet the vaping habits of different customers and avoiding excessive e-liquid entering the atomizing core assembly 9, which would cause oil splatter during inhalation.

[0038] In this embodiment, the top of the battery holder 20 is formed with an upwardly extending extension 27, the top surface of the extension 27 is formed with a groove, and the groove is filled with oil-absorbing cotton 28 for absorbing e-liquid that has not been completely atomized; the bottom surface of the lower seal 6 is formed with a mounting groove 29 for the extension 27 to be inserted, and the top of the mounting groove 29 is provided with an air guide hole 30 that communicates with the atomizing core assembly 9; when the lower housing 2 and the oil cup 1 are snapped together, the extension 27 is inserted into the mounting groove 29, and the outer side wall of the extension 27 is press-fitted with the inner side wall of the mounting groove 29. After installation, the oil-absorbing cotton 28 is placed below the air guide hole 30, and the air guide hole 30 is connected to the air inlet 24. When the user inhales, outside air enters the electronic cigarette through the air inlet 24 and is then guided into the atomizing core assembly 9 through the air guide 30, carrying out the e-liquid heated and atomized by the atomizing core assembly 9. In addition, during the process of adding and atomizing e-liquid by the atomizing core assembly 9, any e-liquid that is not completely atomized will flow downwards and be absorbed by the absorbent cotton 28 after flowing out of the air guide 30, preventing the e-liquid from leaking out of the air inlet 24.

[0039] The base 3 is provided with an oil filling hole 31 that communicates with the oil storage tank 4. An oil filling plug 32 is filled into the oil filling hole 31 to block it. After the e-liquid in the oil storage tank 4 is used up, the lower housing 2 is first removed from the oil cup 1, and then the oil filling plug 32 is removed from the oil filling hole 31. E-liquid can then be injected into the oil storage tank 4 through the oil filling hole 31 to replenish the e-liquid.

[0040] 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.

[0041] 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.
