Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aerosol generating devices, in particular to an atomizer, an aerosol generating device and a control method. BACKGROUND

[0002] The performance of the core component of the aerosol generating device, the atomizing core, directly affects the user experience, and the wick wetting speed and the liquid leakage risk are key indicators that are contradictory to each other. The prior art usually sets liquid inlet holes with different hole diameters on the atomizing core to balance this contradiction, for example, using large holes to achieve fast wick wetting and using small holes to maintain liquid supply balance during normal use. However, this static hole structure design has inherent defects: if only large holes are provided, although the wick wetting is fast, excessive liquid supply during normal use can easily cause liquid leakage; if only small holes are provided, although the liquid leakage risk is low, the initial wick wetting is slow and the user has to wait for a long time. Although there are some automatic control schemes that use motors to drive the liquid path to be opened or closed, which can effectively solve the problem of liquid leakage in the non-use state, these schemes can usually only realize two states of "opening" or "closing" of the liquid path, and cannot dynamically provide the maximum liquid inlet cross section on a single product to achieve fast wick wetting and then switch to the best liquid inlet cross section to accurately control the liquid. Therefore, designing an atomizing core structure that can provide at least three liquid inlet states to intelligently coordinate the contradiction between wick wetting speed and liquid leakage prevention has become a technical problem to be solved in the field.

[0027] In order to better understand the above technical solutions, the above technical solutions will be described in detail in combination with the drawings and specific embodiments of the specification.

[0028] Embodiment 1 The present embodiment provides an atomizer, such as Figures 1-8As shown, the atomizer comprises a shell, a liquid storage bin arranged in the shell and used for storing tobacco liquid, and an atomizing core, the atomizing core comprising a core body 1 and a regulation assembly 2, the core body 1 being provided with a first liquid inlet hole 11 and a second liquid inlet hole 12, the first liquid inlet hole 11 and the second liquid inlet hole 12 both being in communication with the liquid storage bin, the regulation assembly 2 comprising a driving part 21, an adjusting part 22 and a control part 23, the driving part 21 being in transmission connection with the adjusting part 22, and the control part 23 being connected with the driving part 21; wherein the adjusting part 22 is configured to move relative to the core body 1 and has at least three working states: in a first state, as shown in Figure 1 the adjusting part 22 makes the first liquid inlet hole 11 and the second liquid inlet hole 12 both conductive; in a second state, as shown in Figure 2 the adjusting part 22 closes the first liquid inlet hole 11 and keeps the second liquid inlet hole 12 conductive; and in a third state, as shown in Figure 3 the adjusting part 22 closes the first liquid inlet hole 11 and the second liquid inlet hole 12.

[0029] The core body 1, as the core part of the atomizing core, is provided with the first liquid inlet hole 11 and the second liquid inlet hole 12, and the regulation assembly 2 comprises the driving part 21, the adjusting part 22 and the control part 23, which cooperate together to realize dynamic control of the liquid inlet holes. More specifically, the core body 1 is usually fixed inside the atomizer, and its surface is distributed with liquid inlet holes of different diameters, the adjusting part 22 is sleeved outside the core body 1 and can slide up and down along the axial direction of the core body 1, thereby covering or exposing these liquid inlet holes. The driving part 21 is generally installed on a fixed support and is directly connected with the adjusting part 22 through a transmission member such as a connecting rod, so that the output motion of the driving part 21 can be transmitted to the adjusting part 22. The control part 23 is usually integrated on the main control board PCBA of the electronic cigarette and is electrically connected with the driving part 21, responsible for receiving external signals and issuing control instructions. Overall, the adjusting part 22 and the core body 1 form a relative motion relationship, the driving part 21 as a power source is located on one side of the adjusting part 22, and the control part 23 is independently arranged but electrically connected, ensuring that the components are compactly arranged in space and efficiently cooperated in function. The main role of the core body 1 is to bear the atomization function, and it contains heating wires 13 and liquid storage cotton 14 inside, allowing tobacco liquid to enter through the first liquid inlet hole 11 and the second liquid inlet hole 12, thereby realizing the atomization of tobacco liquid to generate aerosol. The regulation assembly 2 is responsible for intelligently managing the liquid inlet process, wherein the role of the driving part 21 is to provide mechanical power, usually using a motor to generate rotary or linear motion; the adjusting part 22 directly acts on the liquid inlet holes of the core body 1, and switches different liquid inlet states by changing its position, thereby adjusting the on-off of the liquid path; the control part 23 decides and commands the driving part 21 to act based on the signals of sensors such as pneumatic switches, ensuring that the atomizing core automatically adjusts according to the use scenario.

[0030] When the electronic cigarette is first filled with liquid, the control unit 23 detects the start signal and sends a command to the drive unit 21, which moves the adjustment unit 22 to the first state; or before filling, the adjustment unit 22 is in the first state, at which time the adjustment unit 22 makes the first liquid inlet hole 11 and the second liquid inlet hole 12 both conductive, and the liquid quickly enters the core 1 to achieve rapid core wetting; when the control unit 23 detects a trigger signal such as a suction action or a key, it sends a command to the drive unit 21 to move the adjustment unit 22 to the second state. When the user starts to smoke, the control unit 23 controls the drive unit 21 to switch the adjustment unit 22 to the second state according to the trigger signal of the pneumatic switch, i.e. to close the first liquid inlet hole 11 but keep the second liquid inlet hole 12 conductive, which balances the liquid supply and the risk of liquid leakage. When the electronic cigarette is idle, the control unit 23 detects no activity signal, and the drive unit 21 moves the adjustment unit 22 to the third state to close all liquid inlet holes to prevent liquid leakage. Throughout the process, the relative movement of the adjustment unit 22 ensures smooth switching of the liquid inlet state, and the stable structure of the core 1 supports continuous atomization, thereby achieving efficient and adaptive liquid path management.

[0031] The present embodiment effectively solves the contradiction between core wetting speed and liquid leakage risk in the background art through the coordinated design of the core 1 and the control assembly 2. Specifically, the first liquid inlet hole 11 and the second liquid inlet hole 12 on the core 1 provide different liquid inlet cross sections, and the control assembly 2 enables the adjustment unit 22 to dynamically switch between at least three states: in the first state, all liquid inlet holes are open, the liquid inlet cross section is maximized to achieve rapid core wetting and shorten user waiting time; in the second state, only the second liquid inlet hole 12 is conductive, the liquid inlet amount is reduced to maintain the balance of liquid supply during normal use and reduce the risk of liquid leakage; in the third state, all liquid inlet holes are closed to completely eliminate the problem of liquid leakage during non-use. This multi-state control mechanism overcomes the limitations of the static hole structure in the prior art, intelligently coordinates the liquid inlet demand in different scenarios, improves the initial core wetting efficiency, and ensures the reliability of long-term use, thereby optimizing the unity of core wetting speed and liquid leakage prevention performance without overly complicating the structure.

[0032] In specific embodiments, the first liquid inlet hole 11 has a larger hole diameter than the second liquid inlet hole 12.

[0033] The first liquid inlet hole 11 has a larger aperture than the second liquid inlet hole 12, and the core is to give different functions to the two liquid inlet holes by different aperture design. More specifically, the larger first liquid inlet hole 11 mainly undertakes the task of quickly soaking the atomization core, which can provide a larger liquid passage cross-sectional area in the initial liquid injection stage, so that the e-liquid can quickly and massively flow into and penetrate the liquid storage cotton 14 in the core 1, thereby significantly shortening the waiting time required by the user from liquid injection to the first use. While the smaller second liquid inlet hole 12 is mainly responsible for maintaining stable and appropriate liquid supply during normal puffing, its smaller aperture produces higher fluid resistance, limiting the amount of liquid entering per unit time, which effectively prevents the leakage problem that may be caused by excessive liquid supply, while ensuring the supply of liquid required for continuous atomization. Further, this combination of large and small designs cleverly coordinates the contradiction between fast start and stable operation. When the adjusting part 22 is in the first state, both holes are open, and the large hole is used for quick soaking; after switching to the second state, only the small hole works, and it automatically enters the safe mode of liquid saving and leakage prevention. Therefore, this feature is not simply a size change, but through clever structural design, it intelligently allocates liquid inlet roles in different use stages, and ultimately systematically improves the reliability of leakage prevention without sacrificing user experience.

[0034] In specific embodiments, the adjusting part 22 is a sleeve that is sleeved outside the core 1, and the inner wall of the sleeve is provided with an annular liquid collection groove for collecting condensed liquid.

[0035] The adjusting part 22 is a sleeve that is sleeved outside the core 1, and the inner wall of the sleeve is provided with an annular liquid collection groove, which allows the sleeve to actively collect condensed liquid generated during use while performing the function of switching the liquid inlet hole. More specifically, the sleeve is sleeved outside the core 1 and can slide up and down, and by changing its position, it controls the conduction or closing of the first liquid inlet hole 11 and the second liquid inlet hole 12. The annular liquid collection groove is located in the annular groove of the inner wall of the sleeve, which can continuously intercept and converge the condensed liquid seeping from the atomization chamber or the liquid tank during the movement of the sleeve, preventing these liquids from flowing or accumulating randomly in critical parts. This structure has a dual effect: on the one hand, the liquid collection groove acts as a barrier, effectively reducing the risk of condensed liquid leaking to the outside of the electronic cigarette or affecting the circuit components, thereby improving the reliability and service life of the product; on the other hand, by concentrating the collection of condensed liquid, it avoids the interference of the liquid with the relative movement between the sleeve and the core 1, ensuring that the adjusting action is smoother and more accurate, further enhancing the stability and leakage prevention performance of the atomization core during state switching.

[0036] In specific embodiments, a liquid storage cavity is formed inside the sleeve, which is in communication with the bottom of the liquid collection groove through a capillary channel, so that the collected condensed liquid can slowly penetrate and be stored in the liquid storage cavity.

[0037] The sleeve is internally integrated with a liquid storage cavity, which is in communication with the bottom of the annular liquid collection groove on the inner wall of the sleeve through a capillary channel. This design allows the condensed liquid collected by the liquid collection groove to slowly and continuously penetrate into the liquid storage cavity through capillary adsorption and be safely stored. More specifically, the annular liquid collection groove is responsible for intercepting and preliminarily gathering the condensed liquid formed on the surface of the sleeve, and then the capillary channel actively guides the liquid into the specially designed storage space of the liquid storage cavity using its small channel structure to generate capillary force. This structure has multiple effects. First, it manages and accommodates the condensed liquid, effectively preventing the liquid from accumulating or dripping disorderly on the surface of the sleeve or the key parts of the core 1, thereby significantly reducing the risk of circuit short circuit, mechanical movement jam, and other failures caused by condensed liquid leakage, and improving the working reliability and service life of the atomizing core. Furthermore, by transferring the condensed liquid away from the airflow passage and sealing it in the liquid storage cavity, this design fundamentally avoids the accidental inhalation of condensed liquid by the user, effectively preventing abnormal noise and bad taste, and ensuring the purity of the aerosol and the comfort of the smoking experience. Therefore, this seemingly simple liquid storage structure, through the clever cooperation of the capillary channel and the liquid collection groove, not only improves the physical reliability of the product, but also directly optimizes the final user experience.

[0038] In specific embodiments, the driving part 21 includes a motor 211 and a transmission member 212, the transmission member 212 includes a screw rod 2121, a sliding block 2122, and a connecting rod 2123, the screw rod 2121 is connected with the output shaft of the motor 211, the sliding block 2122 is threadedly connected with the screw rod 2121, and the two ends of the connecting rod 2123 are respectively connected with the sliding block 2122 and the adjusting part 22.

[0039] The motor 211 is directly connected with the screw rod 2121 in the transmission member 212 through its output shaft, so that the rotary motion of the motor 211 can be transmitted to the screw rod 2121. The screw rod 2121 is threadedly engaged with a slider 2122, and the two ends of a connecting rod 2123 are respectively connected with the slider 2122 and the sleeve of the actuating member. The motor 211 is usually fixed on the support structure of the atomizing core, the screw rod 2121 extends forward from the output shaft of the motor 211, the slider 2122 is limited in the push block guide rail 31 and can only slide linearly along the axial direction of the screw rod 2121 without rotating, and the connecting rod 2123 is like an arm, one end of which is connected with the slider 2122 and the other end of which drives the sleeve. In this transmission chain, the motor 211 provides a precisely controllable motive force, the screw rod 2121 converts the rotary motion of the motor 211 into linear motion, the slider 2122 converts the rotary thrust of the screw rod 2121 into linear displacement of itself as an intermediary of motion conversion, and the connecting rod 2123 finally transmits the linear motion of the slider 2122 to the adjusting part 22 to control the up-and-down movement thereof.

[0040] After the control part 23 sends the instruction, the motor 211 starts to rotate and synchronously drives the screw rod 2121 connected therewith. Since the slider 2122 is limited in the push block guide rail 31 and can only slide, when the screw rod 2121 rotates, the slider 2122 threadedly engaged with the screw rod 2121 will produce a precise linear displacement along the axial direction of the screw rod 2121. The linear motion of the slider 2122 is then transmitted to the sleeve through the connecting rod 2123 to drive the sleeve to move up and down outside the core body 1, thereby realizing the switching of the working state of the different liquid inlet holes between opening and closing.

[0041] In addition, the screw rod 2121 and the slider 2122 can also be integrally manufactured. This way reduces the independent manufacturing, precision matching and assembling steps of the screw rod 2121 and the slider 2122, reduces the component alignment error in the production process, and improves the assembly efficiency.

[0042] The embodiment precisely and reliably converts the rotary motion of the motor 211 into the linear motion required by the sleeve, ensuring the accuracy of the state switching of the liquid inlet holes. Secondly, through the threaded transmission of the screw rod 2121 and the slider 2122, the motion is decelerated and strengthened, so that the movement of the sleeve is more stable and powerful, and can overcome possible resistance. Further, the whole transmission chain structure is compact and stable in operation, so that the sleeve can quickly and accurately respond to the control signal and reliably switch between the three states of rapid core wetting, normal use and leakage prevention closing, thereby improving the intelligent control level and leakage prevention performance of the atomizing core as a whole.

[0043] In specific embodiments, the atomization core further comprises a fixing support 3, wherein a push block guide rail 31 is arranged on the fixing support 3, and the sliding block 2122 is in sliding fit with the push block guide rail 31.

[0044] The atomization core comprises a fixing support 3, wherein a push block guide rail 31 is arranged on the fixing support 3, and the sliding block 2122 in the transmission member 212 is in sliding fit with the push block guide rail 31. More specifically, the fixing support 3 serves as a basic installation platform for the entire transmission mechanism, and the push block guide rail 31 is usually an accurately processed groove or a raised track, into which the sliding block 2122 is embedded or clamped, so that the sliding block 2122 can only move linearly and reciprocally along the path defined by the push block guide rail 31, and cannot rotate or deviate.

[0045] The push block guide rail 31 in the present embodiment provides the sliding block 2122 with forced movement guidance and reliable limiting, and ensures that the sliding block 2122 can only move strictly along the preset linear direction when the screw rod 2121 rotates, so as to accurately convert the rotary motion of the motor 211 into the required linear output, and avoid the possible sticking, shaking or deviation of the sliding block 2122 due to uneven force. Furthermore, the stable guidance makes the movement trajectory of the connecting rod 2123 and the sleeve connected with the sliding block 2123 also very accurate and reliable, and finally ensures that the sleeve can accurately and correctly reach the predetermined position on the core body 1 to open or close the corresponding liquid inlet hole. Therefore, the arrangement of the fixing support 3 and the push block guide rail 31 improves the stability, accuracy and long-term working reliability of the movement of the entire control assembly 2.

[0046] In specific embodiments, the atomization core further comprises a balance rod 4, wherein the balance rod 4 is arranged in parallel with the connecting rod 2123, and two ends thereof are respectively connected with the sliding block 2122 and the sleeve.

[0047] The balance bar 4 is parallel to the connecting rod 2123 of the driving sleeve, and its two ends are connected with the slider 2122 that drives it to move and the sleeve that is driven by it, respectively. This design is equivalent to adding a parallel and symmetrical support point for the movement of the sleeve. When the motor 211 drives the slider 2122 through the screw rod 2121, the movement of the slider 2122 will be transmitted to the sleeve through the two parallel bars of the connecting rod 2123 and the balance bar 4. The core role of the balance bar 4 in this process is to provide additional guidance and stable support, and it and the connecting rod 2123 together constitute a stable movement frame, effectively preventing the sleeve from tilting, shaking or being stuck due to unilateral force during the up and down movement. In this way, the entire movement process of the sleeve becomes more stable and smooth, and can always maintain good coaxiality with the core 1, so as to ensure that the annular liquid collecting groove or edge on the inner wall can accurately align and cover the first liquid inlet hole 11 and the second liquid inlet hole 12, and realize controllable and reliable switching of the state of the liquid inlet hole.

[0048] In specific embodiments, the atomizer further comprises a liquid injection part for injecting smoke liquid into the liquid storage compartment. The following settings can be used: mode one, a liquid injection sealing plug is arranged on the atomizer shell, the liquid can be injected by opening the sealing plug, and the sealing plug is closed after injection to achieve sealing; mode two, a liquid injection structure is arranged on the atomizer base, and the liquid is injected through the liquid injection channel on the base and then sealed; mode three, an opening is formed between the suction nozzle and the atomizer shell before they are assembled, which serves as a liquid injection part, and the suction nozzle and the shell are assembled and fixed after the liquid injection is completed to achieve sealing.

[0049] The specific working process of the atomizer provided in Embodiment 1 is as follows: The whole working process starts from the control unit 23 receiving an external signal, for example, when the electronic cigarette is first filled with liquid, the control unit 23 will detect the start signal and immediately issue an instruction to the drive unit 21, the motor 211 in the drive unit 21 starts to rotate, driving the screw rod 2121 connected directly with it to rotate; Because the sliding block 2122 is engaged with the screw rod 2121 through the thread, and the sliding block 2122 is constrained in the push block guide rail 31 of the fixed support 3 and can only slide linearly, therefore the rotation of the screw rod 2121 forces the sliding block 2122 to move accurately along the path of the push block guide rail 31; The movement of the sliding block 2122 is simultaneously transmitted to the sleeve of the adjusting unit 22 through the connecting rod 2123 and the balance rod 4, more specifically, the connecting rod 2123 and the balance rod 4 are arranged in parallel and their two ends are connected with the sliding block 2122 and the sleeve respectively, this symmetrical structure ensures that the sleeve slides smoothly and vertically up and down outside the core 1, without tilting or jamming; In the first state, the sleeve moves to make the first liquid inlet hole 11 and the second liquid inlet hole 12 on the core 1 are both completely exposed, and the tobacco liquid quickly infiltrates the liquid storage cotton inside the core 1 through the first liquid inlet hole 11 with a large aperture, realizing fast wetting of the core; When the control unit 23 detects a normal puffing signal, the drive unit 21 acts again to drive the sleeve to move to the second state through the same transmission chain, at this time the sleeve covers the first liquid inlet hole 11 but keeps the second liquid inlet hole 12 conductive, thereby reducing the liquid inlet amount to balance the liquid supply and prevent leakage risk; Further, during non-use, the control unit 23 instructs the drive unit 21 to move the sleeve to the third state based on the shutdown signal, closing all liquid inlet holes to completely prevent liquid leakage; The whole process is intelligently coordinated through the regulating assembly 2, ensuring that the atomizing core efficiently and reliably switches states in different use scenarios, improving the overall performance.

[0050] Embodiment 2 The present embodiment provides an aerosol generating device, which comprises the atomizer as described in embodiment 1.

[0051] The aerosol generating device provided by the embodiment relies on the built-in atomizer as described in Embodiment 1 for core structure and function implementation. More specifically, the device is a complete product with the integrated chip 1 and the control assembly 2 with intelligent control capability inside. The chip 1 is responsible for carrying the e-liquid and atomizing, and the control part 23 in the control assembly 2 serves as the brain of the entire device and is connected with the sensing components such as the pneumatic switch of the device to receive the use state signals in real time. The driving part 21 serves as the execution power source, and the motor 211 starts to work after receiving the instruction from the control part 23, and transmits the power to the sleeve of the adjusting part 22 through the transmission member 212. The sleeve moves up and down outside the chip 1 according to the instruction to accurately control the opening and closing of the first liquid inlet hole 11 and the second liquid inlet hole 12, and realize the automatic switching of the three states of rapid wick wetting, normal use and anti-leakage closing. Therefore, the aerosol generating device is not a simple stacking of components, but an organic whole that can automatically adapt to different use scenarios and optimize user experience through intelligent control of the internal atomizing chip.

[0052] In addition, the aerosol generating device further comprises an atomizer shell 5, and the inside of the atomizer shell 5 forms a liquid storage compartment 51 for storing e-liquid, and the lower end of the liquid storage compartment 51 is connected with an atomizing chip sleeve 52 to jointly form a sealed liquid storage space, which serves to safely contain the e-liquid and provide a liquid source for the atomization process. The aerosol generating device further comprises a sealing member 6, which is specifically a silica gel seat arranged at the bottom of the atomizer to serve as a sealing and supporting function, and serves to prevent e-liquid from leaking from the bottom of the atomizer. The aerosol generating device further comprises a battery 7, which serves to provide power for all electrical components such as the motor 211, the control part 23 and the heating wire 13, wherein the control part 23 is a PCBA board. The aerosol generating device further comprises a support housing 8, which mainly comprises a bottom shell constituting the bottom structure of the device, and serves to provide a stable mounting base and structural protection for all internal components such as the atomizing chip and the motor 211.

[0053] Embodiment 3 The embodiment provides a control method of an atomizer, which is based on the atomizer as described in Embodiment 1, as shown in Figure 9 The method comprises the following steps: acquiring a state signal; based on the state signal, issuing a control instruction to the driving part 21 through the control part 23; and the driving part 21 drives the adjusting part 22 to switch between at least three working states according to the control instruction; wherein the at least three working states comprise: a first state in which the first liquid inlet hole 11 and the second liquid inlet hole 12 are both open; a second state in which the first liquid inlet hole 11 is closed and the second liquid inlet hole 12 is open; and a third state in which the first liquid inlet hole 11 and the second liquid inlet hole 12 are both closed.

[0054] The core of this control method is to give the atomizing core an intelligent response working cycle. It starts with the control unit 23 obtaining a key state signal, then the control unit 23 will issue a precise control instruction corresponding to the specific meaning of this signal to the driving unit 21. After receiving the instruction, the driving unit 21 immediately acts, and the motor 211 starts to work, transmits power to the adjusting unit 22 through the transmission member 212, and finally drives the sleeve to move on the core 1, so as to switch between the three preset working states. More specifically, the three states constitute an optimal working process: the first state is to open the first liquid inlet hole 11 and the second liquid inlet hole 12 at the same time, aiming to realize fast core wetting; the second state is to close the first liquid inlet hole 11 but keep the second liquid inlet hole 12 open, so as to balance the liquid supply and prevent leakage; the third state is to completely close all liquid inlet holes, completely eliminating the risk of liquid leakage. This method makes the atomizing core change from a static and passive component to a system that can intelligently perceive the situation and dynamically adjust its behavior. It solves the contradiction between fast core wetting and preventing leakage, and the user can use it without waiting, while enjoying lower risk of leakage during normal smoking and idle period, improving the product's ease of use, safety and overall user experience.

[0055] In specific embodiments, the step of "based on the state signal, the control unit 23 issues a control instruction to the driving unit 21" includes: when the state signal is a start signal after the first liquid injection, control the adjusting unit 22 to move to the first state; or before liquid injection, the adjusting unit is pre-set to the first state; when the state signal is a normal smoking start signal, control the adjusting unit 22 to move to the second state; when the state signal is a stop signal, control the adjusting unit 22 to move to the third state.

[0056] When the state signal acquired by the control unit 23 is identified as the start signal after the first priming, it will immediately issue an instruction to the driving unit 21, and the driving unit 21 will act accordingly to move the sleeve of the adjusting unit 22 to the first state; or before priming, the adjusting unit 22 is in the first state in advance, at this time the adjusting unit 22 makes the first liquid inlet hole 11 and the second liquid inlet hole 12 both conductive, and the tobacco liquid quickly enters the core 1 to achieve rapid wetting of the core; When the control unit 23 detects a suction action or a key trigger signal, it will issue an instruction to the driving unit 21 to move the adjusting unit 22 to the second state. At this time, the first liquid inlet hole 11 and the second liquid inlet hole 12 on the core 1 are all open, and the tobacco liquid can quickly pass through the first liquid inlet hole 11 with a larger aperture to fully soak the liquid storage cotton 14, achieving rapid wetting of the core, and the user can use it without long waiting. When the state signal is the start signal of normal suction, it indicates that the device has ended the initial wetting stage and entered daily use, and the control unit 23 will instruct the driving unit 21 to switch the adjusting unit 22 to the second state, the sleeve closes the first liquid inlet hole 11 but keeps the second liquid inlet hole 12 conductive, which not only ensures the supply of liquid required for continuous atomization, but also significantly reduces the risk of liquid leakage caused by excessive liquid inlet. Further, when the control unit 23 receives a stop signal, meaning that the device has not been used for a period of time, it will control the driving unit 21 to place the adjusting unit 22 in the third state, and the sleeve moves downward to close the first liquid inlet hole 11 and the second liquid inlet hole 12, thereby completely blocking the liquid path and effectively preventing liquid leakage during idle.

[0057] In specific embodiments, before the step of "controlling the adjusting unit 22 to move to the second state when the state signal is the start signal of normal suction", it further includes: after the adjusting unit 22 is in the first state for a preset wetting time, controlling it to move to the second state.

[0058] When the control unit 23 sets the adjusting unit 22 in the first state due to the first priming, the system will not immediately switch to the second state when the user first sucks, but will start an internal timing function to let the adjusting unit 22 maintain in the first state for a pre-set wetting time. During this waiting period to ensure full soaking, the liquid storage cotton 14 in the core 1 can absorb sufficient tobacco liquid through the completely open first liquid inlet hole 11 and second liquid inlet hole 12. Only when this pre-set time is over, the control unit 23 will issue an instruction to the driving unit 21 to move the adjusting unit 22 to the second state of closing the first liquid inlet hole 11 and only keeping the second liquid inlet hole 12 conductive when it receives the start signal of normal suction next time.

[0059] The embodiment fundamentally ensures that the atomizing core can reach a complete and uniform wetting state before being put into normal use through mandatory time guarantee, effectively avoids the dry burning phenomenon caused by insufficient wetting of the core, thereby protecting the heating wire 13 and improving the taste of suction and the durability of the atomizing core. This automatic delay switching separates the user operation from the complex technical judgment, and the user only needs to simply fill the liquid and wait for a moment to obtain the best use experience, without self-estimation or operation, which simplifies the use steps and eliminates the risk of unbalanced liquid supply or liquid leakage caused by early start of suction or forgetting to manually switch, significantly improving the ease of use, safety and intelligent degree of the product.

[0060] In specific embodiments, the start signal and the stop signal are generated by a state of a pneumatic switch; wherein the start signal is generated in response to the pneumatic switch being triggered, and the stop signal is generated after the pneumatic switch is not triggered for a preset time.

[0061] The starting point of the whole control logic is the pneumatic switch. When the user performs a suction action, airflow changes will be generated inside the device, which will trigger the pneumatic switch. The pneumatic switch will then change its state to a clear start signal and send it to the control unit 23, which is equivalent to telling the system that the user is using it. On the contrary, when the suction stops and the airflow returns to normal, the pneumatic switch will reset. The control unit 23 will continuously monitor the state of the pneumatic switch. If it finds that the pneumatic switch has remained in a static state without being triggered for a continuous preset time, it will generate a stop signal based on this, which indicates that the system determines that the device has entered idle. This signal generation method based on physical action triggering and timing judgment realizes highly automated and user-friendly control. It enables the device to accurately simulate human usage habits and achieve the intelligent behavior of "suction and use, no suction and turn off". The user does not need to perform any additional switching operation, which greatly simplifies the operation steps and improves the convenience, and ensures that the device automatically enters the third state of preventing liquid leakage when the hand is idle, fundamentally eliminating the risk of liquid leakage caused by forgetting to turn off, and also helps to save power and prolong the service life of the device.

[0062] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
