Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, and more specifically, to a rotary atomizer and an electronic cigarette. Background Technology

[0002] Traditional electronic cigarette atomizers typically employ independent liquid and airflow control structures. Their atomizing components require electronic sensors or mechanical valves to separately regulate the liquid atomization supply and airflow. For example, some products use airflow-sensing switches to trigger coil heating, but this design relies on precision electronic components (such as pressure sensors and solenoid valves (Hall switches), leading to high costs and the risk of circuit failure. Other solutions use mechanical one-way valves to control the liquid path, but these are prone to leakage due to aging seals over long-term use. Furthermore, some existing atomizers cannot reliably shut off the liquid and airflow simultaneously when not in use, allowing liquid atomization to seep into the airflow through the coil, causing leakage or contamination. Utility Model Content

[0003] The purpose of this invention is to overcome the defects of the prior art and provide a rotary atomizer and electronic cigarette. The atomizer achieves simultaneous closed or open control of the liquid path and the gas path through an innovative rotary mechanical structure, which effectively solves the technical problems of high cost, easy failure and high risk of leakage caused by the complex mechanical structure and high dependence on electronic components of existing products.

[0006] The atomizing seat is disposed inside the upper housing. The base assembly includes an atomizing tube that extends into the upper housing through the central hole of the atomizing seat. The upper housing, the atomizing tube, the atomizing seat, and the base assembly are coaxially connected to each other. The space between the upper housing, the atomizing tube, and the atomizing seat forms an annular liquid storage chamber for storing liquid atomized material. The upper housing drives the atomizing seat to rotate around the central axis of the upper housing, thereby causing relative motion between the atomizing seat and the base assembly including the atomizing tube.

[0007] The upper surface of the atomizing base is provided with two centrally symmetrical liquid inlet grooves, the side wall of the atomizing tube is provided with a liquid inlet hole communicating with the liquid storage chamber, the liquid inlet grooves are connected to the liquid inlet hole, and the atomizing tube is provided with an atomizing core inside; the lower surface of the atomizing base is provided with an air inlet groove, the air inlet groove is connected to the air inlet channel of the base assembly; when the atomizing base rotates together with the upper shell, it simultaneously closes or opens the liquid inlet hole and the air inlet channel.

[0008] In one embodiment, the outer peripheral wall of the atomizing seat is provided with an annular sealing rib, which is in interference fit with the inner wall of the upper housing; the outer periphery of the atomizing seat is provided with an axial limiting groove, and the inner wall of the upper housing is provided with an axial limiting post that is engaged with the axial limiting groove, and the axial limiting post is engaged with the axial limiting groove.

[0009] In one embodiment, a sealing portion is provided between the two liquid inlet channels, and the upper surface of the sealing portion is higher than the bottom surface of the liquid inlet channels.

[0010] In one embodiment, when the liquid inlet is in the open state, the liquid inlet channel is radially aligned with the liquid inlet, and the liquid storage chamber, the liquid inlet channel, the liquid inlet and the atomizing tube are connected in sequence; when the liquid inlet is in the closed state, the sealing part abuts against the liquid inlet to form a contact seal.

[0011] In one embodiment, the liquid inlet channel and the air inlet channel are radially aligned along the atomizing seat.

[0012] In one embodiment, the base assembly includes an atomizing tube, a lower housing, a control module, a base connector, and a connecting bracket. The base connector is disposed on and connected to the lower housing. The control module is disposed on the base connector. The connecting bracket is located above the control module. The atomizing tube is disposed on the connecting bracket and coaxially connected to the connecting bracket. The connecting bracket is snapped into the upper housing.

[0013] In one embodiment, the control module includes a power supply component, a wire, a microphone silicone, an airflow sensor, and a control component; the power supply component and the control component are sequentially disposed within the base connector from top to bottom; the airflow sensor is integrated on the control component and fixed between the microphone silicone and the control component; the control component is connected to the power supply component and the atomizing core via the wire.

[0014] In one embodiment, the atomizing tube passes through the central hole of the atomizing seat and is connected to the connecting bracket; the lower surface of the atomizing seat is provided with an air passage sealing rib, and the air intake channel is provided on the connecting bracket. The air intake channel includes a first air intake channel and a second air intake channel; the first air intake channel communicates with the outside, and the second air intake channel communicates with the atomizing tube; when the air intake channel is open, the air intake groove of the atomizing seat rotates to be located between the first air intake channel and the second air intake channel, and the first air intake channel, the air intake groove, the second air intake channel, and the atomizing tube are sequentially connected; when the air intake channel is closed, the air passage sealing rib of the atomizing seat rotates to be located between the first air intake channel and the second air intake channel, and the air passage sealing rib closes the outlet of the first air intake channel and the inlet of the second air intake channel.

[0015] In one embodiment, the outer wall of the connecting bracket is provided with a connecting slider, and the bottom of the upper housing is provided with a connecting groove. The connecting slider is engaged with the connecting groove so that the upper housing drives the atomizing seat to rotate relative to the base assembly.

[0016] An electronic cigarette, comprising the aforementioned rotary atomizer.

[0017] The advantages of this invention compared to existing technologies are as follows: Through the linkage rotation mechanism between the upper housing and the atomizing seat, and utilizing two centrally symmetrical liquid inlet grooves on the surface of the atomizing seat and an air inlet groove on the lower surface, the opening and closing of the liquid and air paths are simultaneously controlled. When the upper housing rotates, the atomizing seat rotates accordingly, causing the liquid inlet groove and liquid inlet hole, and the air inlet groove and air inlet channel to synchronously align and open or be misaligned and closed. This completely replaces traditional electronic sensors or independent valves with a mechanical structure, avoiding reliance on high-cost electronic components and significantly reducing the risk of failure and manufacturing costs. In the closed state, the liquid inlet hole is physically blocked by the atomizing seat, and the air inlet channel is blocked due to the misalignment of the air inlet groove. Both the liquid inlet hole and the air inlet channel are in a closed state, completely isolating the liquid and air paths between the liquid storage chamber and the atomizing seat, preventing liquid leakage and accidental triggering of atomization by external airflow. This fundamentally solves the leakage problem caused by aging seals or failure of one-way valves in traditional atomizers.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0037] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0038] See Figures 1 to 12 As shown, this utility model embodiment discloses a rotary atomizer, including: an upper shell 1, an atomizing seat 2, a support tube 3, and a base assembly 4, wherein the base assembly 4 is connected to the bottom of the upper shell 1;

[0039] The atomizing seat 2 is disposed inside the upper housing 1. The base assembly 4 includes an atomizing tube 41, which extends into the upper housing 1 through the central hole of the atomizing seat 2. The upper housing 1, the atomizing tube 41, the atomizing seat 2, and the base assembly 4 are coaxially connected to each other. The space between the upper housing 1, the atomizing tube 41, and the atomizing seat 2 forms an annular liquid storage chamber 11 for storing liquid atomized material. The upper housing 1 drives the atomizing seat 2 to rotate around the central axis of the upper housing 1, thereby causing relative movement between the atomizing seat 2 and the base assembly 4 including the atomizing tube 41.

[0040] The upper surface of the atomizing base 2 is provided with two centrally symmetrical liquid inlet grooves 21. The side wall of the atomizing tube 41 is provided with a liquid inlet hole 411 that communicates with the liquid storage chamber 11. The liquid inlet grooves 21 communicate with the liquid inlet hole 411. The atomizing tube 41 is provided with an atomizing core 412 inside. The lower surface of the atomizing base 2 is provided with an air inlet groove 23 that communicates with the air inlet channel 451 of the base assembly 4. When the atomizing base 2 rotates together with the upper shell 1, it simultaneously closes or opens the liquid inlet hole 411 and the air inlet channel 451.

[0041] Specifically, through the linkage rotation mechanism between the upper housing 1 and the atomizing seat 2, the opening and closing of the liquid and air passages are synchronously controlled using two centrally symmetrical liquid inlet grooves 21 on the surface of the atomizing seat 2 and an air inlet groove 23 on the lower surface. When the upper housing 1 is rotated, the atomizing seat 2 rotates accordingly, causing the liquid inlet groove 21 and the liquid inlet hole 411, and the air inlet groove 23 and the air inlet channel 451 to be synchronously aligned and opened or misaligned and closed. This completely replaces traditional electronic sensors or independent valves with mechanical structures, avoiding reliance on high-cost electronic components and significantly reducing the risk of failure and manufacturing costs. In the closed state, the liquid inlet hole 411 is physically blocked by the atomizing seat 2, and the air inlet channel 451 is blocked by the misalignment of the air inlet groove 23. Both the liquid inlet hole 411 and the air inlet channel 451 are in a closed state, thereby completely isolating the liquid and air passages between the liquid storage chamber 11 and the atomizing seat 2, preventing liquid leakage and external airflow from accidentally triggering atomization, and fundamentally solving the leakage problem caused by aging seals or failure of one-way valves in traditional atomizers.

[0042] It should be understood that the atomizing core 412, as the core component for atomizing liquid atomized materials, mainly consists of a heating element 413 and a liquid guiding structure 414. The liquid guiding structure 414 is typically made of cotton or ceramic material, possessing good liquid absorption and high-temperature resistance, and can efficiently absorb the liquid entering the atomizing tube 41 through the liquid inlet 411. The heating element 413 is generally a metal wire located inside the liquid guiding structure 414, usually made of iron-chromium-aluminum alloy or nickel-chromium alloy, which can quickly generate heat after being energized. This structural design allows the liquid in the storage chamber 11 to directly contact the liquid guiding structure 414 of the atomizing core 412 after entering the atomizing tube 41 through the side wall liquid inlet 411, thus achieving atomization after the liquid contacts the heating element 413. It should be understood that in this embodiment, the air inlet slots 23 are preferably also configured as two centrally symmetrical slots for ease of assembly. However, in other embodiments, the number of air inlet channels 23 can be one or more, and they only need to be aligned vertically with one of the liquid inlet channels 21 to achieve the function of liquid inlet while ensuring air passage.

[0043] It should be understood that in this embodiment, the selected atomizer achieves automatic start-stop based on the response mechanism of the airflow sensor 4331 (microphone). The airflow sensor 4331 is installed in the base assembly 4 to monitor changes in external airflow in real time. A mouthpiece 14 is located on the top of the outer casing and is connected to the atomizing tube 41. The air intake channel 451 is used for gas flow. When the user inhales through the mouthpiece 14, external air enters through the air intake port 421. The airflow sensor 4331 senses the change in airflow intensity, and air flows in through the air intake channel 451, thereby triggering the atomizing core 412 to operate. When the user stops inhaling or the air intake channel 451 is closed, the airflow in the air intake channel 451 disappears, the airflow sensor 4331 detects a weakened or no airflow signal, and the atomizing core 412 stops working, avoiding energy waste and preventing excessive liquid atomization and dry burning due to accidental circuit triggering.

[0044] In one embodiment, the outer peripheral wall of the atomizing seat 2 is provided with an annular sealing rib 24, which is in interference fit with the inner wall of the upper housing 1; the outer periphery of the atomizing seat 2 is provided with an axial limiting groove 25, and the inner wall of the upper housing 1 is provided with an axial limiting post 12 that is correspondingly engaged with the axial limiting groove 25, which is engaged with the axial limiting groove 25.

[0045] Specifically, the stable installation and precise positioning of the atomizing seat 2 are achieved through a double limiting structure. An annular sealing rib 24 is provided on its outer peripheral wall, which presses against the inner wall of the upper housing 1 to form a tight radial seal, effectively preventing liquid leakage from the liquid storage chamber 11. Simultaneously, an axial limiting groove 25 is provided on the outer periphery of the atomizing seat 2, and an axial limiting post 12 is correspondingly provided on the inner wall of the upper housing 1. The axial limiting post 12 is engaged within the axial limiting groove 25, preventing the atomizing seat 2 from moving circumferentially relative to the upper housing 1; it can only rotate with the upper housing 1. This ensures that during rotation, the liquid inlet groove 21, the air inlet groove 23, the liquid inlet hole 411, and the air inlet channel 451 always maintain an accurate correspondence, providing a stable structural foundation for the normal operation of the atomizer and avoiding problems such as poor liquid or air intake due to displacement of the atomizing seat 2. Meanwhile, the stable structure ensures that the atomizing core 412 can continuously and stably receive liquid atomized material and perform atomization work, preventing the liquid supply and atomization effect from being affected by component shaking.

[0046] In one embodiment, a sealing part 22 is provided between the two liquid inlet channels 21, and the upper surface of the sealing part 22 is higher than the bottom surface of the liquid inlet channel 21.

[0047] Specifically, a sealing part 22 is provided between the two liquid inlet channels 21 on the atomizing base 2, and the upper surface of the sealing part 22 is higher than the bottom surface of the liquid inlet channel 21, forming a stepped structure. During the liquid inlet process, the liquid inlet channel 21 is used to guide the liquid flow, and the sealing part 22 will not interfere with the liquid inlet; when it is necessary to close the liquid inlet hole 411, taking advantage of the structural feature that the sealing part 22 is higher than the liquid inlet channel 21, the sealing part 22 can fit tightly with the liquid inlet hole 411 when the atomizing base 2 is rotated, thereby blocking the liquid flow path. Through the difference in structural height, the switching between liquid inlet and sealing functions is realized, which not only ensures the smoothness of the liquid inlet operation, but also ensures the sealing of the liquid storage chamber 11, preventing liquid overflow and waste or pollution. Stable liquid inlet control continuously provides liquid atomized material to the atomizing core 412, ensuring the continuity and stability of the atomization process.

[0048] In one embodiment, when the liquid inlet 411 is in the open state, the liquid inlet channel 21 is radially aligned with the liquid inlet 411, and the liquid storage chamber 11, the liquid inlet channel 21, the liquid inlet 411 and the atomizing tube 41 are connected in sequence; when the liquid inlet 411 is in the closed state, the sealing part 22 abuts against the liquid inlet 411 to form a contact seal.

[0049] Specifically, the opening and closing state of the liquid inlet 411 is precisely controlled by the rotation of the atomizing seat 2. When the liquid inlet 411 is open, the atomizing seat 2 rotates until the liquid inlet channel 21 is radially aligned with the liquid inlet 411. At this time, the liquid storage chamber 11, the liquid inlet channel 21, and the liquid inlet 411 are connected in sequence. Under the action of gravity, the liquid flows from the liquid storage chamber 11 through the liquid inlet channel 21 and the liquid inlet 411 into the atomizing tube 41, directly contacting the liquid guiding structure 414 of the atomizing core 412. When the liquid inlet 411 needs to be closed, the atomizing seat 2 continues to rotate, causing the sealing part 22 to move to the liquid inlet 411 and fit tightly against it, forming a reliable contact seal and preventing liquid leakage. This design ensures the stability and reliability of the opening and closing state of the liquid inlet 411, guarantees the smooth progress of the liquid inlet process, and effectively prevents liquid leakage when no liquid is being inlet, thus improving the safety and reliability of the atomizer during transportation and use. Accurate liquid inlet control ensures the stable operation of the atomizer core 412, preventing liquid leakage or abnormal supply from affecting atomizer performance.

[0050] In one embodiment, the liquid inlet channel 21 and the air inlet channel 23 are radially aligned along the atomizing seat 2.

[0051] Specifically, the liquid inlet channel 21 and the air inlet channel 23 are radially aligned along the atomizing seat 2. This design achieves coordinated control of the liquid inlet and air inlet functions. It should be understood that in this embodiment, the air inlet channels 23 are configured as two centrally symmetrical channels. However, in other embodiments, one or more air inlet channels 23 radially aligned with one or more liquid inlet channels 21 can also achieve coordinated control of the liquid inlet and air inlet functions. When the user rotates the upper housing 1 to move the atomizer seat 2, aligning the liquid inlet groove 21 with the liquid inlet hole 411 to open the liquid inlet, the air inlet groove 23 will simultaneously align with the air inlet channel 451 due to their radial alignment. At this time, external air can enter the atomizer core 412 through the air inlet channel 451, providing conditions for the airflow sensor 4331 located at the bottom of the atomizer to sense changes in airflow. After the liquid inlet is completed, rotating the atomizer seat 2 again closes the liquid inlet hole 411 with the sealing part 22, and the air inlet groove 23 and the air inlet channel 451 are also closed simultaneously, preventing airflow from entering and stopping the atomizer from working. This design optimizes the atomizer's workflow, ensuring efficient operation and stable switching between different modes such as liquid inlet, atomization, and closure. The coordinated liquid inlet and air inlet control ensures that the atomizer core 412 receives appropriate airflow while obtaining liquid atomized material, achieving the best atomization effect.

[0052] In one embodiment, the base assembly 4 includes an atomizing tube 41, a lower housing 42, a control module 43, a base connector 44, and a connecting bracket 45. The base connector 44 is disposed on and connected to the lower housing 42. The control module 43 is disposed on the base connector 44. The connecting bracket 45 is located above the control module 43. The atomizing tube 41 is disposed on the connecting bracket 45 and coaxially connected to the connecting bracket 45. The connecting bracket 45 is snapped into the upper housing 1.

[0053] Specifically, the base assembly 4, as an important component of the atomizer, includes an atomizing tube 41, a lower housing 42, a control module 43, a base connector 44, and a connecting bracket 45. The lower housing 42 provides a stable support structure for the base connector 44. The control module 43 is located within the base connector 44, and the connecting bracket 45 is located above the control module 43, providing a cavity for it. The connecting bracket 45 provides a stable support structure for the atomizing tube 41 and connects it to the upper housing 1, making the overall structure modular and improving the integration and assembly convenience of the internal components. The control module 43 is the core of the atomizer's intelligent control, integrating various key components and responsible for processing sensor signals, controlling power output, and other functions. This ensures that the atomizer, triggered by the control module 43, can accurately control the working state of the atomizing coil 412, achieving automatic atomization and shutdown. The control module 43 precisely regulates the power output, providing stable power to the heating element 413 of the atomizing coil 412, ensuring stable heating for efficient atomization. It should be understood that the base assembly 4 also includes an outer shell 48, which is disposed on the lower shell 42 and on the outer wall of the base connector 44. The connecting bracket 45 is connected to the outer shell 48 and the upper shell 1, thereby protecting the base connector 44 and the control module 43.

[0054] In one embodiment, the control module 43 includes a power supply component 431, a wire 4332, a microphone silicone 4333, an airflow sensor 4331, and a control component 432; the power supply component 431 and the control component 432 are sequentially disposed within the base connector 44 from top to bottom; the airflow sensor 4331 is integrated on the control component 432 and fixed between the microphone silicone 4333 and the control component 432; the control component 432 is connected to the power supply component 431 and the atomizing core 412 through the wire 4332.

[0055] Specifically, the power supply component 431 provides power to the atomizer and is the energy source for heating the atomizer core 412 and operating the control component 432. The airflow sensor 4331 is integrated into the control component 432 and is fixed and sealed by the microphone silicone 4333. The power supply component 431 is connected to the control component 432 via a wire 4332. The control component 432 controls the power supply component 431 to supply power to the atomizer core 412 based on the signal emitted by the airflow sensor 4331. When the airflow sensor 4331 detects inhalation airflow, the control component 432 controls the power supply component 431 to supply power to the atomizer core 412, causing the atomizer core 412 to start working; when the airflow disappears, the control component 432 cuts off the power supply to the power supply component 431, stopping the atomizer core 412 from working.

[0056] In one embodiment, the atomizing tube 41 passes through the atomizing base 2 and is connected to the connecting bracket 45; the lower surface of the atomizing base 2 is provided with an air passage sealing rib 26, and the air intake channel 451 is disposed on the connecting bracket 45. The air intake channel 451 includes a first air intake channel 4511 and a second air intake channel 4512; the first air intake channel 4511 communicates with the outside, and the second air intake channel 4512 communicates with the atomizing tube 41; when the air intake channel 451 is opened, the air intake groove 23 of the atomizing base 2 rotates. The first air intake 4511, the air intake channel 23, the second air intake 4512, and the atomizing tube 41 are connected in sequence between the first air intake 4511 and the second air intake 4512. When the air intake channel 451 is closed, the air passage sealing rib 26 of the atomizing seat 2 rotates to be located between the first air intake 4511 and the second air intake 4512, and the air passage sealing rib 26 seals the outlet of the first air intake 4511 and the inlet of the second air intake 4512.

[0057] Specifically, the atomizing tube 41 passes through the central hole of the atomizing base 2 and is connected to the connecting bracket 45, providing stable support for the entire atomizing channel. The lower surface of the atomizing base 2 is provided with an air passage sealing rib 26, which is press-fitted to the upper surface of the connecting bracket 45. Simultaneously, the connecting bracket 45 is provided with an air intake channel 451 to guide airflow. The air intake channel 451, located on the connecting bracket 45, consists of a first air intake channel 4511 and a second air intake channel 4512, which are independent of each other. The first air intake channel 4511 connects to the air inlet 421, which is connected to the outside and serves as the entrance for external airflow into the atomizer. The second air intake channel 4512 connects to the atomizing tube 41 and communicates with the space where the atomizing core 412 is located. When the air intake channel 451 is opened, the air intake slot 23 of the atomizing seat 2 rotates to be located between the first air intake channel 4511 and the second air intake channel 4512. External air enters the atomizing tube 41 in sequence through the air intake port 421, the airflow sensor 4331, the first air intake channel 4511, the air intake slot 23, and the second air intake channel 4512, and flows around the atomizing core 412. At this time, the airflow sensor 4331 on the control component 432 senses the change in airflow and transmits the signal to the control component 432, triggering the control component 432 to control the power supply component 431 to supply power to the atomizing core 412, so that the atomizing core 412 heats up and atomizes the liquid atomized material into steam. The steam mixes with the air and is discharged through the atomizing tube 41. When the air intake channel 451 is closed, the air intake groove 23 of the atomizer base 2 rotates to the closed state with the air intake channel 451. The air passage sealing rib 26 is tightly attached to the outlet of the first air intake channel 4511 and the inlet of the second air intake channel 4512, thereby closing the air intake channel 451. External air cannot enter, the airflow sensor 4331 cannot detect changes in airflow, the control component 432 remains de-energized, and the atomizer core 412 stops working. At this time, the liquid inlet hole 411 is simultaneously sealed by the sealing part 22, forming a double sealing structure, which prevents liquid leakage and avoids dry burning caused by accidental circuit triggering. It should be understood that the bottom of the lower housing 42 is provided with an air inlet 421 that connects to the outside. When the user starts to inhale, the airflow passes sequentially through the air inlet 421, the base connector 44, the microphone silicone 4333, the airflow sensor 4331, the air intake channel 451, the atomizer tube 41, and the mouthpiece 14. The independent airflow design avoids chaotic airflow, ensuring stable air intake and enabling the airflow sensor 4331 to accurately detect airflow changes, thus ensuring the reliability of the atomizer's operation. Stable air intake creates a suitable air environment around the atomizing core 412, which helps the liquid to be fully atomized and smoothly carries out the atomized vapor.

[0058] In one embodiment, the outer wall of the connecting bracket 45 is provided with a connecting slider 452, and the bottom of the upper housing 1 is provided with a connecting groove 13.

[0059] Specifically, a connecting slider 452 is provided on the outer wall of the connecting bracket 45, and a corresponding connecting groove 13 is provided on the bottom of the upper housing 1. The connecting slider 452 is engaged in the connecting groove 13, forming a rotary transmission structure. When the user rotates the upper housing 1, the connecting slider 452 slides in the connecting groove 13. Due to the engagement relationship between the two, the atomizer seat 2 rotates synchronously relative to the base assembly 4. Through this simple and effective mechanical cooperation structure, the rotation control of the atomizer seat 2 by the upper housing 1 is realized, thereby precisely controlling the opening and closing states of the liquid inlet 411 and the air intake channel 451. This connection method has a simple structure, is easy to manufacture and install, and the rotation operation is flexible and smooth. Users can easily switch the working mode of the atomizer by rotating the upper housing 1, while ensuring the accurate relative position of each component during rotation, ensuring the normal operation of the atomizer. The stable rotary drive structure ensures precise control of liquid and air intake, providing reliable external conditions for the stable operation of the atomizer core 412.

[0060] In one embodiment, a support tube 3 is provided between the atomizing seat 2 and the atomizing tube 41 to prevent the atomizing seat 2 and the atomizing tube 41 from deforming due to the interference fit between the airway sealing rib 26 and the connecting bracket 45, thereby making the structure of the rotary atomizer more stable.

[0061] In one embodiment, a bracket silicone 46 is provided below the connecting bracket 45. The bracket silicone 46 seals the bottom area of ​​the connecting bracket 45 except for the air inlet of the first air inlet 4511, thereby ensuring that gas can only enter through the first air inlet 4511. A bracket sealing ring 453 is also provided between the connecting bracket 45 and the outer shell 48, thereby preventing external gas from entering the base connector 44 and the interior of the connecting bracket 45 from the gap between the upper shell 1 and the outer shell 48.

[0062] Preferably, absorbent cotton 47 is provided at other locations between the connecting bracket 45 and the bracket silicone 46, except for the air inlet channel 451, to absorb any remaining smoke and condensate in the storage atomizing tube 41.

[0063] In one embodiment, the bottom of the base connector 44 is provided with an adjustment block (not shown in the figure), and the lower housing 42 is rotatably connected to the base connector 44, so that by rotating the lower housing 42, the inner side of the air inlet 421 can be partially covered by the adjustment block, thereby achieving the function of adjusting the air intake volume.

[0064] Preferably, a connecting sealing ring 441 is provided at the rotatable connection between the base connector 44 and the lower housing 42, thereby preventing gas from entering the base connector 44 from the connection and allowing adjustment of the tightness of the rotatable connection. This provides damping force for the rotation of the lower housing 42 on the one hand, and facilitates user adjustment of the air intake on the other.

[0065] An electronic cigarette includes the rotary atomizer described above. The electronic cigarette employing the rotary atomizer provided in this embodiment achieves efficient and safe atomization through a collaborative design of mechanical rotation control and airflow sensing triggering. The integrated control of liquid intake and atomization via rotation ensures atomization efficiency while effectively preventing leakage and accidental dry burning through a double-sealed structure, thus improving safety and user experience during transportation and use.
