Description

Technical Field

[0001] This invention belongs to the field of electronic cigarettes, and specifically relates to a method, device and electronic cigarette for preventing accidental locking during light inhalation of an electronic cigarette. Background Technology

[0002] When a user inhales an e-cigarette, the e-cigarette converts the user's suction force into a change in capacitance. The chip detects this change in capacitance and converts it into an electrical signal. This electrical signal is then processed into an airflow detection signal. The e-cigarette is activated when the percentage value corresponding to the airflow detection signal is greater than a preset threshold, and is deactivated when the percentage value is less than or equal to the preset threshold. To prevent children from accidentally inhaling e-cigarettes, a locking function is usually required.

[0003] Traditional e-cigarettes with child locks lock by detecting the number of puffs within a limited time. For example, if a cigarette is puffed three times in 1.5 seconds, meaning there are three consecutive airflow detection signals exceeding a preset threshold within 1.5 seconds, the e-cigarette is locked.

[0004] However, when a person gently inhales an e-cigarette, the suction power may be at the level that would just turn the e-cigarette on. Since a person cannot precisely control and maintain a constant suction power, the suction power may fluctuate, meaning the e-cigarette may be on and off at different times. Therefore, once the locking conditions of the traditional e-cigarette locking method are met, the e-cigarette will be locked. It is evident that the traditional e-cigarette locking method is prone to accidental locking when gently inhaling, which will seriously affect the user's smoking experience. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention provides a method, apparatus, and electronic cigarette to prevent accidental locking during light inhalation of an electronic cigarette. The technical problem to be solved by this invention is achieved through the following technical solution:

[0006] In a first aspect, embodiments of the present invention provide a method for preventing accidental locking during the light inhalation of an electronic cigarette, the method comprising:

[0007] Determine the percentage value representing the magnitude of the airflow detection signal in the electronic cigarette;

[0008] The percentage value is compared with a preset smoking threshold and a locking threshold; wherein the smoking threshold is less than the locking threshold.

[0009] The electronic cigarette status is controlled based on the comparison results, including: if the percentage value is less than or equal to the smoking threshold, the electronic cigarette is not turned on; if the percentage value is greater than the smoking threshold, the electronic cigarette is turned on; if the percentage value is greater than the locking threshold, it is determined whether the number of times the percentage value is continuously greater than the locking threshold within a preset time period reaches a preset value. If yes, the electronic cigarette is locked; otherwise, the electronic cigarette continues to work.

[0010] In one embodiment of the present invention, determining the percentage value characterizing the magnitude of the airflow detection signal of the electronic cigarette includes:

[0011] Acquire the initial smoking clock signal generated by the smoking detection circuit and the initial reference clock signal generated by the reference circuit when no user smoking action occurs; and acquire the smoking clock signal generated by the smoking detection circuit and the reference clock signal generated by the reference circuit when a user smoking action occurs.

[0012] Based on the initial smoking clock signal, the initial reference clock signal, the smoking clock signal, and the reference clock signal, a percentage value representing the magnitude of the airflow detection signal of the electronic cigarette is determined.

[0013] In one embodiment of the present invention, the smoking detection circuit and the reference circuit include an oscillator.

[0014] In one embodiment of the present invention, determining the percentage value characterizing the magnitude of the airflow detection signal of the electronic cigarette based on the initial smoking clock signal, the initial reference clock signal, the smoking clock signal, and the reference clock signal includes:

[0015] The initial smoking clock signal, the initial reference clock signal, the smoking clock signal, and the reference clock signal are input into a preset frequency discriminator;

[0016] Using the processing unit in the preset frequency discriminator, a first value is determined based on the ratio of the initial smoking clock signal to the initial reference clock signal;

[0017] The second value is determined based on the ratio of the smoking clock signal to the reference clock signal;

[0018] Calculate the percentage of the difference between the second value and the first value relative to the first value to obtain the percentage value.

[0019] In one embodiment of the present invention, comparing the percentage value with preset smoking thresholds and lockout thresholds includes:

[0020] The percentage value is input into the first and second frequency discrimination units in the preset frequency discriminator;

[0021] The first frequency discrimination unit compares the percentage value with the preset smoking threshold. If the percentage value is greater than the preset smoking threshold, the first frequency discrimination unit outputs a first level value. If the percentage value is less than or equal to the preset smoking threshold, the first frequency discrimination unit outputs a second level value.

[0022] The second frequency discrimination unit compares the percentage value with the preset locking threshold. If the percentage value is greater than the preset locking threshold, the second frequency discrimination unit outputs a first level value. If the percentage value is less than or equal to the preset locking threshold, the second frequency discrimination unit outputs a second level value.

[0023] In one embodiment of the present invention, the step of controlling the electronic cigarette state based on the comparison result includes:

[0024] The first level value output by the second frequency discrimination unit is input to the lock unit, and the second level value output by the second frequency discrimination unit and all level values ​​output by the first frequency discrimination unit are input to the control unit.

[0025] If the control unit receives the second level value output by the first frequency discrimination unit, it provides corresponding feedback to the driving unit, which then controls the electronic cigarette not to be turned on.

[0026] If the control unit receives the first level value output by the first frequency discrimination unit, it sends corresponding feedback to the driving unit, which then controls the electronic cigarette to be turned on.

[0027] If the locking unit receives the first level value output by the second frequency discrimination unit, the locking unit starts its internal timing circuit to begin timing, and simultaneously starts its internal counting circuit to count the number of times the locking unit continuously receives the first level value output by the second frequency discrimination unit within the preset time period. If the count value reaches the preset value, the locking unit provides corresponding feedback to the driving unit, and the driving unit controls the locking of the electronic cigarette; otherwise, the electronic cigarette remains in an unlocked state.

[0028] In one embodiment of the invention, the smoking threshold includes 3%, and the locking threshold includes 6%.

[0029] In one embodiment of the present invention, the preset duration includes 1.5 seconds, and the preset value includes 3 times.

[0030] Secondly, embodiments of the present invention provide a device for preventing accidental locking during light inhalation of an electronic cigarette, the device comprising:

[0031] The percentage value determination module is used to determine the percentage value that characterizes the magnitude of the airflow detection signal of the electronic cigarette;

[0032] A comparison module is used to compare the percentage value with a preset smoking threshold and a locking threshold; wherein the smoking threshold is less than the locking threshold;

[0033] The control module is used to control the electronic cigarette status based on the comparison result, including: if the percentage value is less than or equal to the smoking threshold, the electronic cigarette is not turned on; if the percentage value is greater than the smoking threshold, the electronic cigarette is turned on; if the percentage value is greater than the locking threshold, it is determined whether the number of times the percentage value is continuously greater than the locking threshold within a preset time period reaches a preset value. If yes, the electronic cigarette is locked; otherwise, the electronic cigarette continues to work.

[0034] Thirdly, embodiments of the present invention provide an electronic cigarette that uses the method described in the first aspect for preventing accidental locking during light inhalation of the electronic cigarette to control the electronic cigarette's state.

[0035] In the solution provided by this invention, two thresholds are preset: a smoking threshold and a locking threshold, with the smoking threshold being less than the locking threshold. The electronic cigarette is activated when the percentage value of the airflow detection signal representing the electronic cigarette's strength exceeds the smoking threshold; however, it is locked only when the percentage value continuously exceeds the locking threshold a preset number of times within a preset time period. Thus, even if uneven suction causes the electronic cigarette to repeatedly activate and deactivate near the smoking threshold while the user is lightly inhaling, the electronic cigarette will not lock unless the percentage value continuously exceeds the smoking threshold a preset number of times within the preset time period, which is not met. Therefore, the problem of accidental locking by the user during light inhalation can be solved. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] In a first aspect, embodiments of the present invention provide a method for preventing accidental locking during the light inhalation of an electronic cigarette, such as... Figure 1 As shown, it may include the following steps:

[0044] S1, determine the percentage value representing the magnitude of the airflow detection signal of the electronic cigarette;

[0045] In one optional implementation, S1 may include the following steps:

[0046] S11, acquire the initial smoking clock signal generated by the smoking detection circuit and the initial reference clock signal generated by the reference circuit when no user smoking action occurs; and acquire the smoking clock signal generated by the smoking detection circuit and the reference clock signal generated by the reference circuit when a user smoking action occurs.

[0047] S12, based on the initial smoking clock signal, the initial reference clock signal, the smoking clock signal, and the reference clock signal, determine a percentage value characterizing the magnitude of the airflow detection signal of the electronic cigarette.

[0048] The smoking detection circuit and the reference circuit may include an oscillator. In one optional embodiment, the specific forms of the smoking detection circuit and the reference circuit can be understood by referring to Figures 2(a) and 2(b), respectively, and will not be described in detail here.

[0049] Specifically, S12 may include:

[0050] 1) Input the initial smoking clock signal, the initial reference clock signal, the smoking clock signal, and the reference clock signal into a preset frequency discriminator;

[0051] Please see Figure 3 , Figure 3This is a schematic diagram of the circuit structure of an electronic cigarette in an embodiment of the present invention. For ease of distinction, when the user is not smoking, the initial smoking clock signal generated by the smoking detection circuit and the initial reference clock signal generated by the reference circuit are shown as dashed lines. When the user is smoking, the smoking clock signal generated by the smoking detection circuit and the reference clock signal generated by the reference circuit are shown as solid lines. These four signals are input to the processing unit in the preset frequency discriminator.

[0052] For ease of understanding and explanation, the initial smoking clock signal, the initial reference clock signal, the smoking clock signal, and the reference clock signal are respectively represented as T. ini T inr T1 and T 1ref .

[0053] 2) Using the processing unit in the preset frequency discriminator, determine the first value based on the ratio of the initial smoking clock signal to the initial reference clock signal;

[0054] Specifically, this step involves multiplying the initial smoking clock signal by a preset parameter value, and then calculating the ratio of the product to the initial reference clock signal to obtain the first value. The corresponding calculation process can be expressed as follows:

[0055]

[0056] Where A1 represents the first value; P represents the preset parameter value, which can be 1024.

[0057] The processing unit in this embodiment of the invention can be implemented using any circuit or device with data computing capabilities, and no specific limitations are imposed here.

[0058] 3) Determine the second value based on the ratio of the smoking clock signal to the reference clock signal;

[0059] Specifically, this is still achieved using the processing unit within the preset frequency discriminator. This step multiplies the smoking clock signal and the preset parameter value, then calculates the ratio of the product to the reference clock signal to obtain the second value. The corresponding calculation process can be expressed as follows:

[0060]

[0061] Where B1 represents the second value.

[0062] 4) Calculate the percentage of the difference between the second value and the first value relative to the first value to obtain the percentage value.

[0063] The calculation process for this step can be represented as follows:

[0064]

[0065] Where T represents the percentage value.

[0066] For information on steps S11 to S12 above, please refer to the existing understanding of the working principle of electronic cigarettes.

[0067] S2, compare the percentage value with the preset smoking threshold and locking threshold;

[0068] Those skilled in the art will understand that traditional electronic cigarettes only have a preset threshold, which is used to turn on the electronic cigarette when the percentage value is greater than the preset threshold, and not to turn on the electronic cigarette when the percentage value is less than or equal to the preset threshold. Furthermore, when the number of times the electronic cigarette is turned on consecutively within a limited time reaches a predetermined number, that is, when the number of times the percentage value is greater than the preset threshold consecutively within a limited time reaches a predetermined number, the electronic cigarette is locked.

[0069] It can be seen that the threshold for both starting and locking an e-cigarette in traditional e-cigarettes is the same. Therefore, if a user lightly inhales the e-cigarette, there may be a switching action, making it easy to meet the traditional locking condition of the e-cigarette being turned on and off a predetermined number of times within a limited time, such as three consecutive switching actions within 1.5 seconds. This can easily lead to a situation where the user does not want to lock the e-cigarette, but the e-cigarette is actually locked, thus seriously affecting the user's smoking experience.

[0070] In this embodiment of the invention, two thresholds are set: a smoking threshold and a locking threshold, wherein the smoking threshold is less than the locking threshold. The smoking threshold and the locking threshold can be manually set based on actual measurements of human e-cigarette use. For example, in one optional embodiment, the smoking threshold may be 3%, and the locking threshold may be 6%. Of course, the values ​​of the smoking threshold and the locking threshold are not limited to those shown above.

[0071] See Figure 3 Understandably, in one alternative implementation, S2 may include the following steps:

[0072] S21, input the percentage value into the first and second frequency discrimination units in the preset frequency discriminator;

[0073] In this embodiment of the invention, the processing unit is connected to the first frequency discrimination unit and the second frequency discrimination unit. The first frequency discrimination unit and the second frequency discrimination unit can be implemented using a frequency discrimination circuit, and the specific structure is not limited here.

[0074] S22, the first frequency discrimination unit compares the percentage value with the preset smoking threshold. If the percentage value is greater than the preset smoking threshold, the first frequency discrimination unit outputs a first level value. If the percentage value is less than or equal to the preset smoking threshold, the first frequency discrimination unit outputs a second level value.

[0075] The first frequency discrimination unit is equipped with the preset smoking threshold.

[0076] In one optional implementation, the first level value in S22 can be 1, and the second level value can be 0; then, for S22, if the percentage value is greater than the preset smoking threshold, the first frequency discrimination unit outputs a level value of 1, and if the percentage value is less than or equal to the preset smoking threshold, the first frequency discrimination unit outputs a level value of 0.

[0077] Of course, the above examples are not intended to limit the values ​​of the first and second level values ​​in the embodiments of the present invention.

[0078] S23, the second frequency discrimination unit compares the percentage value with the preset locking threshold. If the percentage value is greater than the preset locking threshold, the second frequency discrimination unit outputs a first level value. If the percentage value is less than or equal to the preset locking threshold, the second frequency discrimination unit outputs a second level value.

[0079] The second frequency discrimination unit is equipped with the preset locking threshold.

[0080] Similar to S22, in one optional implementation, the first level value in S23 can be 1, and the second level value can be 0; then, for S23, if the percentage value is greater than the preset locking threshold, the second frequency discrimination unit outputs a level value of 1, and if the percentage value is less than or equal to the preset locking threshold, the second frequency discrimination unit outputs a level value of 0.

[0081] S3, control the electronic cigarette status based on the comparison result, including: if the percentage value is less than or equal to the smoking threshold, do not turn on the electronic cigarette; if the percentage value is greater than the smoking threshold, turn on the electronic cigarette; if the percentage value is greater than the locking threshold, determine whether the number of times the percentage value is continuously greater than the locking threshold within a preset time period reaches a preset value; if yes, lock the electronic cigarette; if no, keep the electronic cigarette working.

[0082] See also Figure 3 In one optional implementation, controlling the electronic cigarette state based on the comparison result includes the following steps:

[0083] ① The first level value output by the second frequency discrimination unit is input to the lock unit, and the second level value output by the second frequency discrimination unit and all level values ​​output by the first frequency discrimination unit are input to the control unit;

[0084] For example, the level value 1 is input to the lock unit only when the level value output by the second frequency discriminator is 1, and the level value 0 is input to the control unit when the level value output by the second frequency discriminator is 0. Moreover, the level value 1 or level value 0 output by the first frequency discriminator is input to the control unit.

[0085] It is understandable that the control unit performs corresponding processing based on the different level values ​​received from the first frequency discriminator and the second frequency discriminator.

[0086] ②If the control unit receives the second level value output by the first frequency discrimination unit, it provides corresponding feedback to the driving unit, which then controls the electronic cigarette not to be turned on.

[0087] Using the example above, if the control unit receives a level value of 0 from the first frequency discrimination unit, it provides corresponding feedback to the driving unit, which then controls the electronic cigarette not to be turned on. Specifically, the control unit can output a level value of 0 to the driving unit, and the driving unit, upon receiving the level value of 0, also outputs a level value of 0, using the level value of 0 output by the driving unit to control the electronic cigarette not to be turned on.

[0088] ③ If the control unit receives the first level value output by the first frequency discrimination unit, it provides corresponding feedback to the driving unit, which then controls the electronic cigarette to be turned on.

[0089] If the control unit receives a level value of 1 from the first frequency discrimination unit, it sends corresponding feedback to the driving unit, which then controls the electronic cigarette to be turned on. Specifically, the control unit can output a level value of 1 to the driving unit, and the driving unit, upon receiving the level value of 1, also outputs a level value of 1, using the level value of 1 output by the driving unit to control the electronic cigarette to be turned on.

[0090] ④ If the locking unit receives the first level value output by the second frequency discrimination unit, the locking unit starts the internal timing circuit to start timing, and at the same time starts the internal counting circuit to count the number of times the locking unit continuously receives the first level value output by the second frequency discrimination unit within the preset time period. If the count value reaches the preset value, the locking unit provides corresponding feedback to the driving unit, and the driving unit controls the locking of the electronic cigarette; otherwise, the electronic cigarette remains in the unlocked state.

[0091] If the first frequency discrimination unit outputs a level value of 1 to the control unit, and the second frequency discrimination unit also outputs a level value of 1 to the locking unit, then the locking unit, triggered by the level value of 1 output by the second frequency discrimination unit, will activate the timing and counting circuits inside the locking unit. For a schematic diagram of the internal structure of the locking unit, please refer to... Figure 4 understand.

[0092] Specifically, the timing circuit is used for timing and feeding back the timing result to the counting circuit. The counting circuit is used to count the number of times the locking unit continuously receives the level value 1 output by the second frequency discrimination unit, and to count the value when the timing circuit reaches the preset duration, and to determine whether the count value reaches the preset value; if it does, the locking unit can output a level value 0 to the driving unit to feed back the need for a state change, and the driving unit locks the electronic cigarette after receiving the level value 0; if it does not reach the preset value, the locking unit does not feed back the state change to the driving unit, and the electronic cigarette remains in an unlocked state, and the electronic cigarette continues to work.

[0093] The preset duration and preset value can be reasonably set according to the locking requirements. For example, in one optional implementation, the preset duration includes 1.5 seconds and the preset value includes 3 times. Alternatively, the preset duration can be 3 seconds and the preset value can be 5 times, etc., without specific limitations.

[0094] To clearly illustrate the working principle of preventing accidental locking during light inhalation of an electronic cigarette according to the embodiments of the present invention, please refer to Figures 5(a) and 5(b). Figures 5(a) and 5(b) are schematic diagrams of the locking principle of a traditional electronic cigarette and the locking principle of an electronic cigarette according to the embodiments of the present invention, respectively. The suction force corresponds to the airflow detection signal, which is represented by a percentage value. The 0 or 1 in the output curve indicates the level value output by the drive unit.

[0095] The following example illustrates that in the traditional electronic cigarette corresponding to Figure 5(a), if the percentage value representing the magnitude of the airflow detection signal is greater than the threshold three times consecutively within the time range represented by the double vertical lines, the locking condition is met and the electronic cigarette is locked; accordingly, in the output curve, the output level is 0 after the locking condition is met, so as to control the completion of locking the electronic cigarette.

[0096] In Figure 5(b) of this embodiment, threshold 1 represents the smoking threshold, and threshold 2 represents the locking threshold, with threshold 2 being greater than threshold 1. When a user lightly inhales the e-cigarette, uneven suction occurs, causing the e-cigarette to switch on and off around threshold 1. Within the time range indicated by the double vertical lines, the percentage value representing the airflow detection signal magnitude will be greater than threshold 1 three times consecutively. However, this does not meet the locking condition, as the locking condition is only met when the percentage value representing the airflow detection signal magnitude is greater than threshold 2 three times consecutively within this time range. When a user needs to lock the e-cigarette, they must be inhaling normally, meaning the percentage value representing the airflow detection signal magnitude must be greater than threshold 2, and the percentage value must be greater than threshold 2 three times consecutively within a defined time range to lock the e-cigarette. Therefore, this embodiment of the invention can prevent users from accidentally locking the e-cigarette while lightly inhaling.

[0097] In the solution provided by this invention, two thresholds are preset: a smoking threshold and a locking threshold, with the smoking threshold being less than the locking threshold. The electronic cigarette is activated when the percentage value of the airflow detection signal representing the electronic cigarette's strength exceeds the smoking threshold; however, it is locked only when the percentage value continuously exceeds the locking threshold a preset number of times within a preset time period. Thus, even if uneven suction causes the electronic cigarette to repeatedly activate and deactivate near the smoking threshold while the user is lightly inhaling, the electronic cigarette will not lock unless the percentage value continuously exceeds the smoking threshold a preset number of times within the preset time period, which is not met. Therefore, the problem of accidental locking by the user during light inhalation can be solved.

[0098] Secondly, corresponding to the above method embodiments, this invention also provides a device to prevent accidental locking during light inhalation of an electronic cigarette, such as... Figure 6 As shown, the device includes:

[0099] The percentage value determination module 601 is used to determine the percentage value that characterizes the magnitude of the airflow detection signal of the electronic cigarette;

[0100] Comparison module 602 is used to compare the percentage value with a preset smoking threshold and a locking threshold; wherein the smoking threshold is less than the locking threshold;

[0101] Control module 603 is used to control the state of electronic cigarettes based on comparison results, including: if the percentage value is less than or equal to the smoking threshold, the electronic cigarette is not turned on; if the percentage value is greater than the smoking threshold, the electronic cigarette is turned on; if the percentage value is greater than the locking threshold, it is determined whether the number of times the percentage value is continuously greater than the locking threshold within a preset time period reaches a preset value; if yes, the electronic cigarette is locked; if no, the electronic cigarette continues to work.

[0102] The percentage value determination module 601 and the comparison module 602 can form the preset frequency discriminator described above, wherein the percentage value determination module 601 corresponds to the processing unit in the preset frequency discriminator, and the comparison module 602 corresponds to the first frequency discriminator and the second frequency discriminator in the preset frequency discriminator. The control module 603 may include the control unit, the locking unit, and the drive unit described above.

[0103] For details on the specific working process of the percentage value determination module 601, comparison module 602, and control module 603, please refer to the relevant content of the method for preventing accidental locking during light inhalation of electronic cigarettes described in the first aspect; it will not be repeated here.

[0104] The device for preventing accidental locking of an electronic cigarette during light inhalation provided in this invention includes two preset thresholds: a smoking threshold and a locking threshold, with the smoking threshold being lower than the locking threshold. The electronic cigarette is activated when the percentage value of the airflow detection signal representing the electronic cigarette's strength exceeds the smoking threshold; however, it is only locked when the percentage value exceeds the locking threshold a preset number of times within a preset time period. Thus, even if uneven suction causes the electronic cigarette to repeatedly activate and deactivate near the smoking threshold during light inhalation, the device will not lock unless the percentage value exceeds the locking threshold a preset number of times within the preset time period. Therefore, the problem of accidental locking during light inhalation can be solved.

[0105] Thirdly, embodiments of the present invention provide an electronic cigarette that uses the method described in the first aspect for preventing accidental locking during light inhalation of the electronic cigarette to control the electronic cigarette's state.

[0106] The specific circuit structure of the electronic cigarette is not limited here. For information on methods to prevent accidental locking during light inhalation, please refer to the relevant content in the first section; they will not be elaborated upon here.

[0107] The electronic cigarette provided in this invention employs a method to prevent accidental locking during light inhalation for electronic cigarette status control. This method pre-sets two thresholds: a smoking threshold and a locking threshold, with the smoking threshold being lower than the locking threshold. The electronic cigarette is activated when the percentage value of the airflow detection signal representing the electronic cigarette's strength exceeds the smoking threshold; however, it is only locked when the percentage value continuously exceeds the locking threshold a preset number of times within a preset time period. Thus, even if uneven suction causes the electronic cigarette to repeatedly activate and deactivate near the smoking threshold during light inhalation, the electronic cigarette will not lock unless the percentage value continuously exceeds the smoking threshold a preset number of times within the preset time period, thus solving the problem of accidental locking during light inhalation.

The method for preventing accidental locking during light inhalation of an electronic cigarette according to claim 4, characterized in that, The step of comparing the percentage value with preset smoking thresholds and lockout thresholds includes: The percentage value is input into the first and second frequency discrimination units in the preset frequency discriminator; The first frequency discrimination unit compares the percentage value with the preset smoking threshold. If the percentage value is greater than the preset smoking threshold, the first frequency discrimination unit outputs a first level value. If the percentage value is less than or equal to the preset smoking threshold, the first frequency discrimination unit outputs a second level value. The second frequency discrimination unit compares the percentage value with the preset locking threshold. If the percentage value is greater than the preset locking threshold, the second frequency discrimination unit outputs a first level value. If the percentage value is less than or equal to the preset locking threshold, the second frequency discrimination unit outputs a second level value.

6. The method for preventing accidental locking during light inhalation of an electronic cigarette according to claim 5, characterized in that, The step of controlling the electronic cigarette status based on the comparison result includes: The first level value output by the second frequency discrimination unit is input to the lock unit, and the second level value output by the second frequency discrimination unit and all level values ​​output by the first frequency discrimination unit are input to the control unit. If the control unit receives the second level value output by the first frequency discrimination unit, it provides corresponding feedback to the driving unit, which then controls the electronic cigarette not to be turned on. If the control unit receives the first level value output by the first frequency discrimination unit, it sends corresponding feedback to the driving unit, which then controls the electronic cigarette to be turned on. If the locking unit receives the first level value output by the second frequency discrimination unit, the locking unit starts its internal timing circuit to begin timing, and simultaneously starts its internal counting circuit to count the number of times the locking unit continuously receives the first level value output by the second frequency discrimination unit within the preset time period. If the count value reaches the preset value, the locking unit provides corresponding feedback to the driving unit, and the driving unit controls the locking of the electronic cigarette; otherwise, the electronic cigarette remains in an unlocked state.
