Description

An electronic atomizer structure Technical Field

[0001] This utility model relates to the field of electronic atomizer technology, and in particular to an electronic atomizer structure. Background Technology

[0002] Currently, most electronic atomizers on the market consist of a battery pack, an atomizing module, and an e-liquid storage module. The battery pack provides power to the entire device, while the atomizing module is responsible for atomizing the e-liquid into an aerosol. Its core component is typically a combination of a heating coil and a wicking cotton. The wicking cotton draws e-liquid from the storage module and conducts it to the heating coil. The heating coil heats up under the influence of the electric current, heating the e-liquid to its atomization temperature, thus producing an aerosol that the user can inhale. The e-liquid storage module generally uses a sealed tank structure, storing e-liquid inside and connected to the atomizing module through wicking holes and other structures to ensure a continuous supply of e-liquid.

[0003] Storage and transportation are indispensable components in the actual production, sales, and use of electronic atomizers. However, due to the complexity and uncontrollability of environmental factors, existing electronic atomizers are prone to leakage during storage and transportation, which has become one of the key bottlenecks restricting the further development of the electronic atomizer industry.

[0004] During storage and transportation, e-cigarettes may be under negative pressure due to factors such as packaging seal and changes in ambient air pressure. For example, when an e-cigarette is sealed in packaging, the air pressure inside the packaging will gradually decrease as the altitude increases or the ambient temperature decreases during transportation, creating a negative pressure environment. Under this negative pressure, the e-liquid inside the e-liquid storage component will be squeezed by the external atmospheric pressure, breaking the originally balanced surface tension of the e-liquid. E-liquid can easily seep out through weak points such as the wicking holes and gaps in the seals, leading to leakage. Once leakage occurs, it not only wastes e-liquid and increases production costs, but the leaked e-liquid may also contaminate the e-cigarette's casing, battery components, and other parts, affecting the device's appearance and performance, and may even cause safety hazards such as short circuits.

[0005] Temperature variations during storage and transportation are also a significant factor contributing to e-cigarette leakage. E-cigarettes may experience rapid transitions between high and low temperatures during transport. When the ambient temperature rises, the viscosity of the e-liquid decreases, increasing its fluidity. Simultaneously, the gas inside the e-liquid storage component expands due to heat, increasing pressure. If the sealing performance of the e-liquid storage component is poor, or its structural design is flawed and unable to effectively withstand internal pressure changes, the e-liquid can easily leak from weak points in the seal under pressure. Conversely, when the ambient temperature drops, the e-liquid contracts, and the gas inside the e-liquid storage component condenses and contracts, creating negative pressure, which also promotes leakage. Furthermore, temperature differences can cause thermal expansion and contraction of the e-liquid storage component materials, altering the fit between the seals and the component, further exacerbating the risk of leakage.

[0006] To address the issue of e-liquid leakage during storage and transportation, the industry has conducted some research and experimentation. For example, some manufacturers have improved the sealing structure of e-liquid storage components by using higher-quality sealing materials to enhance sealing performance and reduce the possibility of leakage. However, these improvements often only alleviate leakage to a certain extent and cannot fundamentally solve the problem of leakage caused by negative pressure or extreme temperature differences. This is because, under complex storage and transportation environments, simply improving sealing performance is insufficient to completely resist the effects of external pressure and temperature changes on the e-liquid storage components. Some manufacturers have also tried adjusting the e-liquid formula to alter its physical properties, such as increasing viscosity, to reduce its fluidity under negative pressure or temperature changes. However, this method may negatively impact the atomization effect and flavor of the e-liquid, leading to a decline in the user experience and failing to meet the market's demand for high-quality e-liquid products.

[0007] In conclusion, the problem of oil leakage caused by negative pressure or high and low temperature differences during storage and transportation of existing electronic atomizers has not been effectively solved. Developing an electronic atomizer technology that can effectively prevent oil leakage has important practical significance and broad market prospects. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an electronic atomizer structure.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0010] This utility model embodiment provides an electronic atomizer structure, including: an oil cup assembly and a battery rod assembly. The oil cup assembly is detachably connected to the battery rod assembly. The outer side of the oil cup assembly has two levels of snap-fit ​​protrusions, and the battery rod assembly has corresponding slots for the snap-fit ​​protrusions. When the oil cup assembly is pressed into the battery rod assembly until the first-level snap-fit ​​protrusion engages with the first-level slot, a half-pressurized state is formed; pressing continues until the second-level snap-fit ​​protrusion engages with the second-level slot, a full-pressurized state is formed.

[0011] In one specific embodiment, the oil cup assembly includes an oil cup component, a bottom cover, an oil-sealing silicone sealant, a support tube, an upper sealing silicone sealant, and a lower sealing silicone sealant. The support tube is installed inside the oil-sealing silicone sealant, the oil-sealing silicone sealant is installed inside the bottom cover, the lower sealing silicone sealant is sleeved on the lower end of the bottom cover, the upper sealing silicone sealant is connected to the upper end of the bottom cover, the bottom cover is inserted into the oil cup component from bottom to top, and the bottom cover and the oil cup component form an oil storage cavity. The snap-fit ​​protrusion is provided on the outer side of the oil cup component.

[0012] In one specific embodiment, the bottom cover is further provided with an oil injection hole, which is connected to the oil storage cavity, and the oil injection hole is connected to an oil injection plug.

[0013] In one specific embodiment, a sealing ring is also provided inside the bottom cover below the sealing silicone.

[0014] In one specific embodiment, the battery rod assembly includes a housing, a bracket, a support base, a core silicone, a core component, a core tube, a metal ring, an oil storage cotton, and an O-ring. The housing has a slot on its inner side, the bracket is installed inside the housing, the support base is connected to the bracket, the core component is connected to the core silicone, the oil storage cotton is sleeved on the core component, the core tube is sleeved on the oil storage cotton and the core silicone, and the lower end of the core tube is connected to the support base, the metal ring is installed on the upper end of the core tube, and the O-ring is sleeved on the metal ring.

[0015] In one specific embodiment, a fiberglass tube is also connected inside the core component.

[0016] In one specific embodiment, a sealing silicone sealant is also provided between the support base and the bracket.

[0017] In one specific embodiment, the bracket is further provided with a PCB board and a battery cell inside, and the battery cell is electrically connected to the PCB board.

[0018] In one specific embodiment, the bracket is further provided with an air inlet, and the air inlet is connected to an air-adjusting silicone.

[0019] In one specific embodiment, the housing is further provided with a gas regulating switch in the area corresponding to the gas regulating silicone.

[0020] The advantages of this electronic atomizer structure compared to existing technologies are as follows: By designing the e-liquid cup assembly and the battery rod assembly as a detachable connection, they can be separated during storage and transportation. This ensures that the e-liquid is completely sealed inside the e-liquid cup assembly, isolating it from the external environment. This fundamentally eliminates the risk of leakage due to weak sealing points in the assembled e-liquid cup and battery rod assemblies, which can be affected by environmental factors. Regardless of pressure changes or temperature fluctuations during transportation, the e-liquid remains securely within the e-liquid cup assembly, preventing leakage from affecting product performance, appearance, and safety. The negative impact of this feature has been mitigated, improving the reliability and stability of e-cigarettes during storage and transportation, reducing product loss rates, and saving costs for companies. Furthermore, when the user presses the e-liquid cup assembly into the battery rod assembly until the second-stage latch protrusion engages with the second-stage slot to form a fully pressurized state, the e-liquid in the cup assembly can quickly and evenly penetrate the heating coil surface under pressure, allowing the heating coil to achieve a good wetting state in a very short time. Users can immediately begin vaping without waiting. This plug-and-play feature improves the convenience and efficiency of using e-cigarettes.

[0037] Referring to the specific embodiments shown in Figures 1 to 7, this utility model discloses an electronic atomizer structure, including: an oil cup assembly 10 and a battery rod assembly 20. The oil cup assembly 10 is detachably connected to the battery rod assembly 20. The outer side of the oil cup assembly 10 is provided with two-stage latching protrusions 111, and the battery rod assembly 20 is provided with a slot 211 corresponding to the latching protrusions 111. When the oil cup assembly 10 is pressed into the battery rod assembly 20 until the first-stage latching protrusion 111 engages with the first-stage slot 211, a half-pressed state is formed; it continues to be pressed in until the second-stage latching protrusion 111 engages with the second-stage slot 211, forming a fully pressed state.

[0038] Specifically, the user holds the oil cup assembly 10 and aligns the end of the oil cup assembly 10 with the snap-fit ​​protrusion 111 with the connection part of the battery rod assembly 20, gently applying downward pressure. As the pressure is applied, the first-stage snap-fit ​​protrusion 111 on the outer side of the oil cup assembly 10 gradually slides into the first-stage slot 211 of the battery rod assembly 20 along the guide surface. When the right-angled surface of the first-stage snap-fit ​​protrusion 111 is tightly fitted with the groove wall of the first-stage slot 211, the oil cup assembly 10 and the battery rod assembly 20 are in a semi-pressed state. At this time, the oil cup assembly 10 is initially fixed to the battery rod assembly 20, but there is still a certain gap between them, allowing the oil cup assembly 10 to wobble slightly within a small range. Based on this semi-pressed state, the user continues to apply downward pressure, further pressing the oil cup assembly 10 into the battery rod assembly 20. The second-stage snap-fit ​​protrusion 111 on the outer side of the oil cup assembly 10 begins to contact the second-stage slot 211 of the battery rod assembly 20 and gradually penetrates deeper along the guide surface of the slot 211. When the second-stage latching protrusion 111 is fully engaged in the second-stage latching groove 211, and its right-angled surface is tightly fitted against the groove wall of the groove 211, the oil cup assembly 10 and the battery rod assembly 20 reach a fully compressed state, achieving a firm and stable connection that can no longer be easily shaken. When it is necessary to disassemble the oil cup assembly 10 and the battery rod assembly 20, the user only needs to pinch the oil cup assembly 10 with their fingers and apply a certain pulling force perpendicular to the connection direction. Due to the special design of the latching protrusion 111 and the latching groove 211, under the action of pulling force, the second-stage latching protrusion 111 will first disengage from the second-stage latching groove 211, and the oil cup assembly 10 and the battery rod assembly 20 will return from the fully compressed state to the semi-compressed state. Continuing to apply pulling force, the first-stage latching protrusion 111 will also slide out from the first-stage latching groove 211, ultimately achieving complete separation of the oil cup assembly 10 and the battery rod assembly 20.

[0039] In other words, by designing the oil cup assembly 10 and the battery rod assembly 20 as a detachable connection, the two can be separated during storage and transportation. In this way, the e-liquid is completely sealed inside the oil cup assembly 10, isolated from the external environment. This fundamentally eliminates the risk of oil leakage due to environmental factors affecting weak sealing points that may exist when the oil cup assembly 10 and the battery rod assembly 20 are assembled. Regardless of any changes in air pressure or temperature fluctuations during transportation, the e-liquid remains securely inside the oil cup assembly 10, avoiding adverse effects on product performance, appearance, and safety caused by oil leakage. This improves the reliability and stability of the electronic atomizer during storage and transportation, reduces product loss rate, and saves costs for the company.

[0040] In addition, when the user presses the oil cup assembly 10 into the battery rod assembly 20 until the second-stage buckle protrusion 111 engages with the second-stage slot 211 to form a fully pressurized state, the e-liquid in the oil cup assembly 10 can quickly and evenly penetrate to the surface of the heating coil under pressure, so that the heating coil reaches a good wetted state in a very short time. The user can start vaping immediately without waiting. This plug-and-play feature improves the convenience and efficiency of the user's use of electronic atomizers.

[0041] In addition, the design of the two-stage buckle protrusion 111 on the outside of the oil cup assembly 10 and the corresponding slot 211 of the battery rod assembly 20 has unique technical advantages. During the assembly process, when the oil cup assembly 10 is pressed into the battery rod assembly 20 until the first-stage buckle protrusion 111 engages with the first-stage slot 211, a semi-pressed state is formed. This semi-pressed state provides the user with a preliminary assembly positioning and plays a certain role in fixing it, preventing the oil cup assembly 10 from easily shaking or shifting during subsequent operations. It also makes it easier for the user to judge whether the assembly has started to be in place, providing a reference for further operations. When the second-stage buckle protrusion 111 engages with the second-stage slot 211 to form a fully pressed state, the oil cup assembly 10 and the battery rod assembly 20 achieve a firm and precise connection. The two-stage snap-fit ​​design not only increases the stability and reliability of the connection, avoiding problems such as poor contact and oil leakage caused by loose connections, but also allows users to clearly perceive whether the assembly is complete and the connection is in place through clear snap-fit ​​feedback. This ensures the stable performance of the product during use, and users can confidently perform suction operations without worrying about the user experience being affected by component connection problems, further improving the overall quality of the product and user satisfaction.

[0042] Referring to Figures 2, 4 to 7, in one embodiment, the oil cup assembly 10 includes an oil cup component 11, a bottom cover 12, an oil-sealing silicone 13, a support tube 14, an upper sealing silicone 15, and a lower sealing silicone 16. The support tube 14 is installed inside the oil-sealing silicone 13, the oil-sealing silicone 13 is installed inside the bottom cover 12, the lower sealing silicone 16 is sleeved on the lower end of the bottom cover 12, the upper sealing silicone 15 is connected to the upper end of the bottom cover 12, the bottom cover 12 is inserted into the oil cup component 11 from bottom to top, and the bottom cover 12 and the oil cup component 11 form an oil storage cavity 17. The snap-fit ​​protrusion 111 is provided on the outer side of the oil cup component 11.

[0043] Specifically, slowly insert the support tube 14 into one end of the sealing silicone 13 until the support tube 14 is completely installed inside the sealing silicone 13. During insertion, ensure that the support tube 14 fits tightly against the inner wall of the sealing silicone 13 without gaps. Applying appropriate pressure can make the bond stronger. Place the sealing silicone 13 with the support tube 14 into the reserved space inside the bottom cover 12, and use the elasticity of the sealing silicone 13 to press it into a tight fit with the bottom cover 12. During pressing, be careful to keep the sealing silicone 13 flat and avoid wrinkles or displacement. Sleeve the lower sealing silicone 16 onto the lower end of the bottom cover 12, ensuring that the lower sealing silicone 16 completely covers the lower end of the bottom cover 12 and fits tightly against it. Slowly insert the bottom cover 12, with the sealing silicone 13, support tube 14, and lower sealing silicone 16 assembled, into the lower opening of the oil cup 11 from bottom to top. During insertion, the positioning structure on the outer side of the bottom cover 12 is used to initially position it against the inner side of the oil cup 11, ensuring that the bottom cover 12 and the oil cup 11 are coaxial. As the bottom cover 12 is inserted, the upper sealing silicone 15 gradually contacts and tightly adheres to the inner wall of the oil cup 11. When the bottom cover 12 is inserted to the appropriate position, a closed oil storage cavity 17 is formed between the bottom cover 12 and the oil cup 11. On the outer side of the oil cup 11, two-stage snap-fit ​​protrusions 111 are integrally formed using an injection molding process.

[0044] In other words, the sealing silicone 13, upper sealing silicone 15, and lower sealing silicone 16 work together to provide multi-layered sealing for the oil storage chamber 17. The sealing silicone 13, installed inside the bottom cover 12, effectively prevents e-liquid leakage from the gap between the bottom cover 12 and the support tube 14. The upper sealing silicone 15, connected to the upper end of the bottom cover 12, fits tightly against the inner wall of the oil cup component 11, preventing e-liquid from seeping out from the connection between the bottom cover 12 and the upper end of the oil cup component 11. The lower sealing silicone 16, fitted onto the lower end of the bottom cover 12, further enhances the sealing at the connection between the bottom cover 12 and the lower end of the oil cup component 11. This multi-component collaborative sealing design significantly reduces the risk of e-liquid leakage, ensuring that e-liquid can be stably stored in the oil storage chamber 17. Furthermore, the oil cup assembly 10 adopts a modular design, with components assembled through simple insertion and fitting, requiring no complex tools or processes. This modular assembly method reduces assembly difficulty and cost during production, improving production efficiency. Meanwhile, for users, the oil cup assembly 10 can be easily disassembled for cleaning, parts replacement, or maintenance. Furthermore, the two-stage snap-fit ​​protrusion 111 on the outer side of the oil cup assembly 11 makes the connection and disassembly between the oil cup assembly 10 and the battery rod assembly 20 more convenient. During assembly, the user simply presses the oil cup assembly 10 into the battery rod assembly 20, and the snap-fit ​​protrusion 111 engages with the slot 211 for a quick connection; during disassembly, applying appropriate pulling force easily separates the two. This design not only improves the user experience but also facilitates the daily maintenance and management of the electronic atomizer.

[0045] Referring to Figures 2, 4 to 7, in one embodiment, the bottom cover 12 is further provided with an oil injection hole, which is connected to the oil storage cavity 17 and is connected to an oil injection plug 18.

[0046] Specifically, the design of the filling hole and the filling plug 18 allows users to easily perform the filling operation. No complicated tools or professional knowledge are required; the filling process can be completed in three simple steps: pulling out the filling plug 18, filling in e-liquid, and inserting the filling plug 18 back in. This greatly improves user convenience, making it especially suitable for everyday use by ordinary consumers. Furthermore, the tight fit between the filling plug 18 and the filling hole effectively prevents e-liquid leakage during storage and use through an elastic seal. Made of silicone or rubber, the filling plug 18 has good elasticity and flexibility, adapting to minor dimensional changes in the inner wall of the filling hole, maintaining a tight fit at all times, ensuring that the e-liquid in the reservoir 17 does not leak out. This avoids problems such as damage to the e-cigarette, environmental pollution, and user inconvenience caused by e-liquid leakage.

[0047] Referring to Figures 2, 4 to 7, in one embodiment, a sealing ring 19 is also provided inside the bottom cover 12 below the sealing silicone 13.

[0048] Specifically, the sealing ring 19 and the sealing silicone 13 together form a multi-level sealing structure inside the bottom cover 12. When the e-liquid cup assembly 10 is pressed into the battery rod assembly 20, the sealing ring 19 forms an additional sealing barrier at the connection between the bottom cover 12 and the battery rod assembly 20, further preventing e-liquid from leaking from the gap between the bottom cover 12 and the battery rod assembly 20. Even if the sealing silicone 13 develops minor sealing defects during long-term use, the sealing ring 19 can still play a crucial sealing role, greatly reducing the risk of e-liquid leakage and ensuring the normal use of the electronic atomizer.

[0049] Referring to Figures 3 to 7, in one embodiment, the battery rod assembly 20 includes a housing 21, a bracket 22, a support base 23, a core silicone 24, a core component 25, a core tube 26, a metal ring 27, an oil-retaining cotton 28, and an O-ring 29. The housing 21 has a slot 211 on its inner side. The bracket 22 is installed inside the housing 21. The support base 23 is connected to the bracket 22. The core component 25 is connected to the core silicone 24. The oil-retaining cotton 28 is sleeved on the core component 25. The core tube 26 is sleeved on the oil-retaining cotton 28 and the core silicone 24, and the lower end of the core tube 26 is connected to the support base 23. The metal ring 27 is installed on the upper end of the core tube 26, and the O-ring 29 is sleeved on the metal ring 27.

[0050] Specifically, insert the core component 25 into the core silicone 24, ensuring a tight, seamless fit between the core component 25 and the core silicone 24. Place the cut oil-retaining cotton 28 onto the core component 25, ensuring even distribution and avoiding areas that are too thick or too thin. Slide the core tube 26 over the combination of the oil-retaining cotton 28 and the core silicone 24 from above, and slowly move the core tube 26 downwards until its lower end connects with the support base 23. During this process, ensure there is no jamming or deformation between the core tube 26 and the oil-retaining cotton 28 or the core silicone 24. Place the metal ring 27 on the upper end of the core tube 26, securing it using either an interference fit or adhesive bonding. If using an interference fit, control the amount of interference to ensure the metal ring 27 is securely installed and does not easily fall off; if using adhesive bonding, select a suitable adhesive and follow the instructions to ensure bonding strength and sealing. Slowly and evenly place the O-ring 29 onto the metal ring 27, ensuring that the O-ring 29 is not twisted, flipped, or damaged. Using an interference fit, slowly press the support base 23 into the mounting hole of the bracket 22. Push the bracket 22 into the housing 21. After installation, the bracket 22 can be fixed and reinforced by methods such as adhesive application, laser welding, or mechanical locking to prevent it from falling off during use due to vibration or external force.

[0051] In other words, the battery rod assembly 20 adopts a modular design concept, with each component being relatively independent yet interconnected, facilitating assembly and disassembly. This improves assembly efficiency and reduces production costs during manufacturing; and during user operation, if a component malfunctions, it facilitates replacement and repair, enhancing product maintainability. Furthermore, the oil-absorbing cotton 28 effectively stores e-liquid and, through its excellent absorption and conduction properties, evenly distributes it to the coil 25. When powered on, the coil 25 atomizes the e-liquid into vapor. The optimal combination of the oil-absorbing cotton 28 and the coil 25 ensures a stable e-liquid supply, thereby improving the stability and uniformity of atomization and providing a better smoking experience. Additionally, the battery rod assembly 20 features a well-designed internal structure. The layout of components such as the coil tube 26 and support base 23 ensures smooth airflow through the atomization area. This efficient airflow channel helps increase vapor production and flavor, resulting in richer, finer vapor and further enhancing the atomization performance of the electronic atomizer.

[0052] Referring to Figures 3 to 7, in one embodiment, a fiberglass tube 212 is also connected inside the core component 25.

[0053] Specifically, the smooth interior of the fiberglass tube 212 provides a stable flow channel for e-liquid, reducing resistance during flow. By precisely controlling the inner diameter and length of the fiberglass tube 212, precise control of the e-liquid flow rate can be achieved, ensuring that the e-liquid enters the atomization area of ​​the coil 25 at the appropriate speed and flow rate, making the atomization process more stable and uniform. For example, during continuous vaping, the fiberglass tube 212 ensures a continuous and stable supply of e-liquid, preventing insufficient atomization or leakage due to interrupted supply or excessive supply. Furthermore, the fiberglass tube 212 has a certain rigidity and stiffness, effectively preventing backflow of e-liquid due to pressure changes during atomization. When the atomizer stops working, the fiberglass tube 212 maintains the normal position of the e-liquid inside the coil 25, preventing backflow into other parts such as the battery assembly 20, thus protecting other components from e-liquid corrosion and extending the product's lifespan.

[0054] Referring to Figures 3 to 7, in one embodiment, a sealing silicone rubber 213 is further provided between the support base 23 and the bracket 22.

[0055] Specifically, the sealing silicone 213 can tightly fit the contact surfaces of the support base 23 and the bracket 22, filling the tiny gaps between them and forming a reliable sealing barrier. In the electronic atomizer, it can effectively prevent external air from entering the battery rod assembly 20, avoiding unnecessary reactions between air and e-liquid or heating elements, while also preventing internal vapor leakage, ensuring the flavor and concentration of the vapor, and improving the user experience.

[0056] Referring to Figures 3 to 7, in one embodiment, the bracket 22 is further provided with a PCB board 214 and a battery cell 215 inside, and the battery cell 215 is electrically connected to the PCB board 214.

[0057] Specifically, the battery cell 215 serves as the power source for the electronic atomizer, providing stable power to the various functional modules on the PCB board 214. The power management module on the PCB board 214 precisely controls the charging and discharging process of the battery cell 215, ensuring it operates within a safe range. It also rationally allocates power according to the atomizer's usage status to guarantee normal operation. For example, when the user is smoking, the power management module provides sufficient current to the atomization control module, driving the heating coil to heat the e-liquid and produce vapor. During charging, it controls the charging current and voltage of the battery cell 215 for fast and safe charging. Furthermore, the atomization control module on the PCB board 214 controls the heating power and time of the heating coil based on user input via buttons. By adjusting the heating parameters, different vapor production and flavor effects can be achieved to meet individual user needs. For example, users can choose a high-power mode to quickly produce a large amount of vapor, or a low-power mode to enjoy a smooth and mellow vapor flavor. Additionally, the indicator light driver module on the PCB board 214 drives the indicator lights to display corresponding information based on the electronic atomizer's operating status. For example, when the battery is low, the indicator light flashes to remind the user to charge; when the atomizer is in operation, the indicator light stays on, indicating normal operation. This status feedback allows users to stay informed about the atomizer's working status, improving convenience and safety.

[0058] Referring to Figures 3 to 7, in one embodiment, the bracket 22 is further provided with an air inlet, which is connected to an air regulating silicone 216; the housing 21 is also provided with an air regulating switch 217 in the area corresponding to the air regulating silicone 216.

[0059] Specifically, different users have different preferences for the taste and concentration of vapor. By operating the vapor adjustment switch 217, users can precisely adjust the airflow. For example, users who prefer a richer vapor can reduce the airflow, lowering the air-to-vapor mixture ratio for a denser vapor; while users who prefer a milder vapor can increase the airflow, increasing the air content for a lighter vapor. Furthermore, precise airflow adjustment ensures a stable airflow around the atomizer coil. A stable airflow allows for complete atomization of the e-liquid, reducing problems such as incomplete atomization, burnt taste, or off-flavors caused by unstable airflow. For example, during vaping, the vapor adjustment switch 217 can adjust the airflow in real time according to the user's vaping intensity and frequency, ensuring consistent vapor quality. Additionally, a stable airflow and good atomization reduce the burden on the atomizer coil and battery, slowing down component wear and aging. Simultaneously, the reliable connection and sealing performance of the vapor adjustment switch 217 and the vapor adjustment silicone 216 ensures stable performance of the e-cigarette during long-term use, extending the overall lifespan of the product.

[0060] Referring to Figure 5, when the oil cup assembly 10 is pre-installed into the battery rod assembly 20, the core tube 26 is aligned with the center hole of the bottom cover 12.

[0061] Specifically, the precise alignment design between the core tube 26 and the center hole of the bottom cover 12 significantly shortens assembly time, whether for automated or manual assembly. Furthermore, the accurate alignment design reduces the operational difficulty of the assembly process and minimizes repeated assembly and adjustments caused by inaccurate alignment.

[0062] Referring to Figure 6, the oil cup assembly 10 is pressed into the battery rod assembly 20 until the first-stage buckle protrusion 111 engages with the first-stage slot 211 to form a half-pressed state. At this time, the O-ring 29 is just pressed in and higher than the oil inlet hole of the bottom cover 12 (the oil inlet hole of the bottom cover 12 is open). At this time, the oil inlet hole of the core tube 26 is not open, and the core component 25 is not filled with oil. This also prevents the oil cup assembly 10 from being pulled out after being pressed in halfway, which would cause oil leakage.

[0063] Referring to Figure 7, the oil cup assembly 10 is pressed into the battery rod assembly 20 until the second-level buckle protrusion 111 engages with the second-level slot 211 to form a fully pressurized state. At this time, the oil inlet of the core tube 26 is connected to the oil inlet of the bottom cover 12. The oil cup 11 is pressed down to allow oil to enter and moisten the core 25. Then, the gas adjustment switch 217 is turned on to smoke.

[0064] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
