In addition, in other embodiments of the present application, the first state is an air suction state or an air blowing state, and the state detection unit includes an air suction detection unit 150, and when the electronic cigarette is sucked, the air suction detection unit 150 determines that the electronic cigarette is in the air suction state; when the electronic cigarette is blown, the blowing detection unit 150 judges that the electronic cigarette is in a blowing state; when the electronic cigarette is not blown or exhausted, the suction and blowing detection unit 150 determines that the electronic cigarette is in a non-suction and blowing state.

Therefore, when the e-cigarette is changed from the uncharged state to the charged state, the charge management unit 120 outputs a signal from the uncharged signal to the charged signal and outputs the signal.

When the third timing unit 250 acquires that the e-cigarette enters the uncharged state, for example, the output signal of the state detection unit changes from the high level signal to the low level signal, the third timing unit 250 stops timing and sets zero, that is, the third timing unit 250 resets.

In general, the false trigger signal duration will be very short and will be less than 10ms, in this embodiment, the third preset duration is generally greater than or equal to 10ms and less than or equal to 100ms, and the third preset duration is, for example, 10ms, 20ms, 30ms, 40ms, 50ms, 60ms, 70ms, 80ms, 90ms, 100ms, etc. In this embodiment, the third duration determining unit 260 and the third timing unit 250 may be implemented in one unit module, for example, a timer, or may be implemented in two or more unit modules.

In other embodiments of the present application, the first timing count determining unit 230 is connected to the first timing unit 210 and the first counting unit 220, when the first timing unit 210 reaches the first preset duration, the first timing unit 210 outputs a signal to the first timing count determining unit 230, the first timing count determining unit 230 obtains the count of the first counting unit 220 at this time, and then determines whether the count number is greater than or equal to the first preset number, if so, a locking signal is output, and if not, the original signal output is maintained.

Specifically, in this 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 state detecting unit and the third time length determining unit 260, the fourth time length determining unit 282 is electrically connected to the fourth timing unit 281 and the third time length determining unit 250, and the third time length determining unit 250 is also electrically connected to the state detecting unit and the third time length determining unit 260. When the third duration determining unit 260 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 250 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 250 is locked, that is, enters the locked state, the third timing unit 250 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 250 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 time 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 time 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 unlocking signal to the third timing unit 250, the third timing unit 250 is unlocked, the third timing unit 250 is in an unlocked state, and thereafter the third timing unit 250 acquires information that the electronic cigarette enters the first state, and the third timing unit 250 can perform timing.

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 250 may count again effectively, that is, after outputting the trigger valid signal, the third timing unit 250 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 addition, in other embodiments of the present application, after step S14, the method further includes:

acquiring information of the electronic cigarette entering a non-first state from the first state;

judging whether the timing duration of the fourth timing unit 281 is greater than or equal to a fourth preset duration;

if the determination results are yes, the third timer unit 250 is reset, and the lock on the count is released.

This embodiment also prevents the signal corresponding to the first state from jittering, resulting in miscounting. Specifically, in this embodiment, referring to fig. 4, 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 state detecting unit and the third time length determining unit 260, the fourth time length determining unit 282 is electrically connected to the fourth timing unit 281, the third timing unit 250 and the first counting unit, and the first counting unit is also electrically connected to the state detecting unit and the third time length determining unit 260. When the third duration determining unit 260 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 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 is locked, namely enters the locking state, the first counting unit does not count and increase even if receiving the trigger valid signal after being locked, namely the first counting unit keeps the original count value in the locking state, the count value is not increased, and only the first counting unit in the unlocking state after being unlocked receives the trigger valid signal and counts and increases one. 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 resets, 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 250, the timing of the third timing unit 250 is stopped and reset, that is, resets, while the fourth time length determining unit outputs an unlock signal to the first counting unit, the first counting unit is unlocked, the first counting unit enters the unlocked state, after which the first counting unit acquires a trigger valid signal again, and the first counting unit 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 the present embodiment, the first timing count determining unit 230 completes the determination before the first timing unit 210 and the first counting unit 220 are reset.

Optionally, the child lock control method further includes: if the time length is smaller than the first preset time length and the count number reaches the first preset number, stopping counting and timing, and setting the count number and the time length to zero.

If the first timing count determining unit 230 obtains that the number counted by the first counting unit 220 reaches the first preset number, and the timing duration of the first timing unit 210 is less than the first preset duration, the first timing count determining unit 230 outputs a signal to the first timing unit 210 and the first counting unit 220, and the first timing unit 210 and the first counting unit 220 are reset, where the signal may be the same as the locking signal or different signals.
