The second child lock state is a child lock unlock state, and the child lock unlock state corresponds to release of the child lock protection function, at this time, when a user draws the electronic cigarette, the switch control module 250 controls the power MOS tube M to be continuously turned on or intermittently turned on, the intermittent conduction means that the switch control module 250 outputs a square wave signal in a PWM manner and a PFM manner, and the switch control module 250 is controlled by the suction and blowing detection module 270 by adjusting a duty ratio of the square wave signal to be used for controlling output power, for example, the second child lock module 220 continuously outputs a high level signal. The present application is not limited thereto, and in other embodiments of the present application, the first child lock state may also be a child lock unlock state, and the second child lock state may be a child lock state.
In this embodiment, when the electronic cigarette enters the second child-lock state, the first timer unit 211 and the first counter unit 212 receive the first reset signal, that is, when the electronic cigarette is in the first child-lock state, whether the first timer unit 211 starts counting or not, the first counter unit 212 is already counting, when the electronic cigarette enters the second child-lock state from the first child-lock state, the first timer unit 211 and the first counter unit 212 both receive the first reset signal, the first timer unit 211 will reset, that is, the first timer unit 211 stops counting and is set to zero, the first counter unit 212 will reset, that is, the first counter unit 212 will stop counting and is set to zero, after that, the user charges, the electronic cigarette enters the charging state, since the first timer unit 211 has not previously started counting, the first counter unit 212 has not started counting previously, so that the first timer unit 211 is triggered to start counting from 0, and when the number of charging plugs in the first preset period is greater than or equal to the first preset number, the first output switch unit 213 keeps the first power-lock control module 250 to keep the first power-off state, and the first switch module 213 keeps the first power-lock control module 250 from continuously turning off. Therefore, the first timing unit 211 and the first counting unit 212 are not in operation all the time, when the user inserts and withdraws the charger connector normally (or sucks and blows) in the child lock locking state (the child lock unlocking state is similar and is not repeated), the first timing unit 211 and the first counting unit 212 are triggered to perform timing and counting, and when the user normally operates the electronic cigarette to enter the child lock unlocking state, the first timing unit 211 is still in timing, the count value of the first counting unit 212 is kept, so that the first child lock module 210 may receive less charging and plugging times than the first preset number in the child lock unlocking state and enter the child lock locking state, logic errors are caused, trouble is caused to the use of the user, and misoperation of the user is easy to cause. For example, in the child lock locking state, the user charges the electronic cigarette normally, the charger connector is inserted into the charging interface 140, at this time, the first counting unit 211 starts to count 1, after the user operates normally to make the electronic cigarette enter the child lock unlocking state, the first counting unit 211 is still counting time, after that, when the electronic cigarette is plugged in and plugged out for 2 times for various reasons, the first preset number is satisfied (assuming that the first preset number is 3 times, and is still within the first preset time period), the first counting and judging unit 213 outputs the first child lock signal, so that the electronic cigarette returns to the child lock locking state, which causes logic confusion in the use process of the user, does not accord with the expectation of the user, causes trouble to the operation of the user, and causes misoperation of the user easily.

When the second child lock module 220 generates a second child lock signal for enabling the electronic cigarette to enter the second child lock state, the trigger 240 receives the second child lock signal and outputs a second signal, the second signal is a high level signal, wherein the edge signal of the trigger 240 converted from the first signal (described later) to the second signal is a first reset signal, the electronic cigarette enters the second child lock state, meanwhile, the first timing unit 211 and the first counting unit 212 receive the first reset signal, the first timing unit 211 stops timing and sets zero, and the first counting unit 212 stops counting and sets zero. How to reset the first timing unit 211 and the first counting unit 212 after receiving the first reset signal is a conventional technology in the art, and will not be described herein.

When the first child lock module 210 outputs a first child lock signal for enabling the electronic cigarette to enter the first child lock state, the trigger 240 continuously outputs a low level signal to the switch control module 250 and the second child lock module 220, the low level signal is the first signal, meanwhile, an edge signal converted from the second signal to the first signal is the second reset signal, the electronic cigarette enters the first child lock state, and the second child lock module 220 receives the second reset signal.
In addition, in other embodiments of the present application, the first timing unit 211 and the first counting unit 212 are electrically connected to the switch control module 250, and the second child lock module 220 is electrically connected to the switch control module 250.

For example, the switch control module 250 further includes a reset unit, which includes two not gates, for example, two not gates connected in series, wherein an input end of one not gate is electrically connected to an output end of the trigger 240, and an output end of the other not gate is electrically connected to the first timing unit 211 and the first counting unit 212, respectively. In addition, in other embodiments of the present application, the reset signal may be inverted, the first reset signal may be an edge signal that changes from a high level signal to a low level signal, and the second reset signal may be an edge signal that changes from a low level signal to a high level signal.
In addition, in other embodiments of the present application, similarly, the first timing unit 211 and the first counting unit 212 are electrically connected to the output end of the second child lock module 220, the second child lock module 220 outputs a second child lock signal for enabling the electronic cigarette to enter the second child lock state, the second child lock module 220 outputs an edge signal from a low level signal to a high level signal as a first reset signal, and in other embodiments of the present application, the first reset signal may be a falling edge signal, the first timing unit 211 receives the first reset signal, the first timing unit 211 stops timing and sets to zero, the first counting unit 212 receives the first reset signal, and the first counting unit 212 stops counting and sets to zero.
In the present embodiment, the second child lock module 220 is similar to the first child lock module 210, and the second child lock module 220 includes a second timing unit 221, a second counting unit 222, and a second timing count determining unit 223. The second timing unit 221 and the second counting unit 222 are electrically connected to the second state detection module, the second timing count determination unit 223 is electrically connected to the second timing unit 221 and the second counting unit 222, respectively, and when the electronic cigarette enters the first child lock state, the second timing unit 221 and the second counting unit 222 receive the second reset signal, so that the second timing unit 221 stops timing and is set to zero, and the second counting unit 222 stops counting and is set to zero. In this embodiment, when the electronic cigarette is in the first child-lock state, the second state detection module outputs the inhalation signal to the second timing unit 221 and the second counting unit 222 when the user inhales the electronic cigarette, the second timing unit 221 starts timing, the second counting unit 222 starts counting, the second timing count determination unit 223 is configured to determine whether the count of the second counting unit 222 is greater than or equal to the second preset number within the second preset time period, and when the second timing count determination unit 223 determines that the count of the second counting unit 222 is greater than or equal to the second preset number within the second preset time period, the second timing count determination unit 223 outputs the second child-lock signal to the trigger 240, and the trigger 240 outputs the second signal to the switch control unit. The specific function of the second child lock module 220 may refer to the first child lock module 210, and will not be described herein. In addition, in other embodiments of the present application, when the second child lock state is the child lock locking state, the second child lock module 220 may not include the second counting unit 222, and the second timing count determining unit 223 is a second duration determining unit, where the electronic cigarette determines whether to enter the second child lock state according to the placement duration.
In this embodiment, the first timing unit 211, the first counting unit 212, the second timing unit 221, and the second counting unit 222 operate regardless of whether the electronic cigarette is in the first child lock state or the second child lock state, and when the trigger signal is received, the first timing unit 211 and the second timing unit 221 correspondingly start timing, and the first counting unit 212 and the second counting unit 222 correspondingly start counting. In the present embodiment, the three units of the second timer unit 221, the second counting unit 222, and the second timer count judgment unit 223 may be implemented by conventional timers and counters, that is, although the foregoing is divided into three units by functions, it is actually possible to implement the two circuit modules, which is also within the scope of the present application. In the present embodiment, the three units of the first timer unit 211, the first counting unit 212, and the first timer count judgment unit 213 may be implemented by a conventional timer and a counter, that is, although the foregoing is divided into three units by functions, it is actually possible to implement the two circuit modules, which is also within the scope of the present application.
The inventor of the present application found that, in the actual testing process, the contact between the charger connector and the charging interface 140 is not stable, or the charger connector and the charging interface 140 are damaged due to long-term use, or shake may cause that the charger connector and the charging interface 140 are plugged once, so that the charging management module 260 detects multiple charging signals, and the charger connector and the charging interface 140 are plugged once, so that the electronic cigarette may be triggered by mistake to enter the first child lock state, which causes trouble to the user, and other triggering modes, such as an air extraction mode (air disturbance caused by environmental factors, temperature factors, etc.), an air blowing mode (air disturbance caused by environmental factors, temperature factors, etc.), and a bullet plugging mode (contact is not stable, use loss, etc.), also have similar problems. To solve this problem, in this embodiment, the child lock control circuit 200 further includes a third timing unit 231 and a third duration determining unit 232, where the third timing unit 231 is electrically connected to the first state detecting module, the third duration determining unit 232 is electrically connected to the third timing unit 231, and an output end of the third duration determining unit 232 is electrically connected to the first timing unit 211 and the first counting unit 212, respectively, and the third duration determining unit 232 is configured to generate a trigger valid signal according to a timing duration of the third timing unit 231. In the present embodiment, the two units of the third time counting unit 231 and the third duration judging unit 232 may be implemented by a conventional timer, that is, although the foregoing two units are functionally divided, they may be implemented by one circuit module in practice, which is also within the scope of the present application.
In this embodiment, when the electronic cigarette enters the charging state, the third time counting unit 231 starts to count, when the third time length determining unit 232 determines that the third time length determining unit 231 counts a third preset time length or more, that is, the duration in the charging state is greater than or equal to the third preset time length, at this time, the third time length determining unit 232 outputs a trigger valid signal to the first time counting unit 211 and the first counting unit 212, the first time counting unit 211 is triggered to start counting, and thereafter, the first time counting unit 211 ignores the output signal of the third time length determining unit 232 as long as the first time counting unit 211 is not reset, and each charging detects and determines the duration of the charging signal, and only if the duration of the charging signal is greater than or equal to the third preset time length, the first counting unit 212 counts. Thereafter, the third timer unit 231 is reset, i.e., stops counting and zeroes. In the first preset duration, if the third duration determining unit 232 determines that the third timing unit 231 counts more than or equal to the third preset duration again next time, the first timing unit 211 ignores the signal, and meanwhile, the first counting unit 212 counts up by 1, that is, the following count all performs detection and determination on the holding duration of the charging signal, and only the holding duration of charging is greater than or equal to the third preset duration. In the present embodiment, the third timing unit 231 starts timing triggered by a rising edge signal (edge signal), a falling edge signal (edge signal), a high level signal (level signal), or a low level signal (level signal), so that when the first state detection module is changed from the uncharged signal to the charged signal, the third timing unit 231 is triggered to start timing.
In addition, the first timing unit 211 may not trigger to start timing by receiving the trigger valid signal, and in other embodiments of the present application, the first timing unit 211 is electrically connected to the first state detection module, the first timing unit 211 obtains information that the electronic cigarette enters the first state, and the first timing unit 211 also performs timing, that is, the first timing unit 211 and the third timing unit 231 perform timing at about the same time. In the present embodiment, the first timing unit 211 performs timing by an edge signal trigger, and the third timing unit 231 performs timing by a level signal trigger or an edge signal trigger.
In this embodiment, when the third time period determining unit 232 determines that the third time period determining unit 231 counts less than the third preset time period, that is, the time period in the charged state is less than the third preset time period, the third time period determining unit 232 does not output the trigger valid signal, for example, outputs the trigger invalid signal, and the trigger invalid signal does not trigger the following circuit timing and counting. In this embodiment, when the duration of the charging signal is very short and the charging signal is changed back to the uncharged signal, the third timing unit 231 stops timing and the timing duration is set to zero, that is, the third timing unit 231 is reset, and at the same time, the third duration judging unit 232 still outputs the trigger invalidation signal. In the present embodiment, the third preset time period is, for example, 10ms, 20ms, 30ms, 40ms, 50ms, 60ms, 70ms, 80ms, 90ms, 100ms, or the like. The foregoing problems occur that the charging signal is generated for a plurality of times during one charging, in general, the duration of the foregoing charging signal is very short and is less than 10ms, the charging signal is greater than or equal to 10ms and less than or equal to 100ms when the charging signal is stably connected, the embodiment uses this mode to distinguish whether the charging signal is effective charging or ineffective charging caused by reason of poor reliability, loss, etc., when the duration of the charging signal is very short, the charging signal is quickly changed back to the uncharged signal, the third timing unit 231 is reset, and meanwhile, the third duration judging unit 232 does not output the triggering effective signal to the first timing unit 211 and the first counting unit 212, so that the first timing unit 211 and the first counting unit 212 are not triggered, and thus are not mistakenly triggered, and the situation that the electronic cigarette is triggered to enter the first child lock state once the charger connector is inserted into the charging interface 140 does not occur.
The embodiment also detects the interval between the first states, and prevents the signal corresponding to the first state from shaking to cause miscounting. Specifically, in the present embodiment, the child lock control circuit includes a fourth timing unit 281 and a fourth time length determining unit 282, the fourth timing unit 281 is electrically connected to the first state detecting module and the third time length determining unit 232, the fourth time length determining unit 282 is electrically connected to the fourth timing unit 281 and the third timing unit 231, and the third timing unit 231 is also electrically connected to the first state detecting module and the third time length determining unit 232. When the third duration determining unit 232 outputs the trigger valid signal, the fourth timing unit 281 obtains the information that the electronic cigarette enters the non-first state from the first state after obtaining the trigger valid signal, for example, the information that the electronic cigarette changes from the charged state to the non-charged state (the non-charged state), for example, the high level signal changes to the low level signal, the fourth timing unit 281 is triggered to start timing, meanwhile, the third timing unit 231 also obtains the information that the electronic cigarette enters the non-first state from the first state after obtaining the trigger valid signal, the third timing unit 231 is locked, that is, enters the locked state, the third timing unit 231 is not triggered to start timing after being locked, and at this time, the timing of the third timing unit 291 is 0, and the third timing unit 231 in the unlocked state only after being unlocked clocks the duration of the first state. In this embodiment, when the fourth timing unit 281 starts timing, the fourth timing unit 281 is always timing, the fourth time length determining unit 282 determines whether the timing duration of the fourth timing unit 281 is greater than or equal to a fourth preset duration, for example, 10ms-100ms, for example, 10ms, 20ms, 30ms, 40ms, 50ms, 60ms, 70ms, 80ms, 90ms, 100ms, etc., and preferably 20ms, and when the fourth time length determining unit 282 determines that the timing of the fourth timing unit 281 reaches the fourth preset duration, the fourth timing unit 281 stops timing and is set to zero, that is, the fourth timing unit 281 is reset, and at the same time, the fourth time length determining unit 282 outputs an unlock signal to the third timing unit 231, the third timing unit 231 is unlocked, the third timing unit 231 is in an unlocked state, and thereafter the third timing unit 231 acquires information that the electronic cigarette enters the first state, and the third timing unit 231 can perform timing. In this embodiment, when the fourth timing unit 281 does not receive the trigger valid signal, the fourth timing unit 281 does not trigger to start timing even if the fourth timing unit 281 acquires information that the electronic cigarette enters the non-first state from the first state. In this embodiment, the duration of the first state is determined, and only the duration is greater than the third preset duration, and meanwhile, after the electronic cigarette is converted from the first state to the non-first state after being counted once, the fourth timing unit 281 counts, and only after the fourth timing unit 281 counts more than or equal to the fourth preset duration, the third timing unit 231 may count again effectively, that is, after the valid triggering signal is output, the third timing unit 231 may count again after waiting for at least the fourth preset duration. the setting can prevent the first state action from shaking to cause the first state action to be mistaken for the first state action for several times, so that the first state action does not meet the expectation of the user, and the setting of the embodiment improves the experience of the user and meets the expectation of the user.
In order to prevent the false count caused by the jitter of the signal corresponding to the first state, in other embodiments of the present application, please refer to fig. 3, the child lock control circuit includes a fourth timing unit 281 and a fourth time length determining unit 282, the fourth timing unit 281 is electrically connected to the first state detecting module and the third time length determining unit 232, the fourth time length determining unit 282 is electrically connected to the fourth timing unit 281, the third timing unit 231 and the first counting unit 212, and the first counting unit 212 is further electrically connected to the first state detecting module and the third time length determining unit 232. When the third duration determining unit 232 outputs the trigger valid signal, the fourth timing unit 281 obtains the information that the electronic cigarette enters the non-first state from the first state after receiving the trigger valid signal, the fourth timing unit 281 is triggered to start timing, meanwhile, the first counting unit 212 also obtains the information that the electronic cigarette enters the non-first state from the first state after obtaining the trigger valid signal, the first counting unit 212 is locked, that is, enters the locked state, the first counting unit 212 does not count up even if receiving the trigger valid signal after being locked, that is, the first counting unit 212 keeps the original count value in the locked state, does not count up, and only when the first counting unit 212 in the unlocked state receives the trigger valid signal after being unlocked, the count is incremented. In this embodiment, when the fourth timing unit 281 starts timing, the fourth timing unit 281 is always timing (even if the state is changed from the non-first state to the first state), the fourth time length determining unit 282 determines whether the timing length of the fourth timing unit 281 is greater than or equal to the fourth preset time length, when the fourth time length determining unit 282 determines that the timing length of the fourth timing unit 281 reaches the fourth preset time length, the fourth timing unit 281 stops timing and sets zero, that is, the fourth timing unit 281 resets, while the fourth time length determining unit 282 outputs a reset signal to the third timing unit 231, the timing of the third timing unit 231 is stopped and sets zero, that is, resets, while the fourth time length determining unit outputs an unlock signal to the first counting unit 212, the first counting unit 212 is unlocked, the first counting unit 212 enters the unlocked state, and thereafter the first counting unit 212 acquires the trigger valid signal again, and the first counting unit 212 may perform a count plus action. In this embodiment, when the fourth timing unit 281 does not receive the trigger valid signal, the fourth timing unit 281 does not trigger the start of timing even if the fourth timing unit 281 acquires information that the electronic cigarette enters the non-first state from the first state.
In this embodiment, the first preset duration and the second preset duration are generally less than or equal to 5s, so that false triggering is prevented, where the first preset duration is, for example, 1s, 1.5s, 1.8s, 2s, 2.3s, 2.5s, 2.8s, 3s, 4s, 5s, and preferably 2s. In this embodiment, the first preset number and the second preset number are greater than or equal to 2, for example, 2, 3, 4,5, 6, etc., preferably 3, and the first preset number and the second preset number are generally less than or equal to 6 times, so as to facilitate the user operation.
