The shutdown mode etc. of consumption；Certainly the power consumption height of each use state described above is opposite.And controller 23 itself energy
Enough having different power consumption mode is to be based on chip in design caused by the setting of its functional structure, and usual chip includes power supply
The functional modules such as manager, host state machine, chip transceiver, central processing unit and memory, and the working performance of modules
It is required that determining the work clock, such as 32MHz, 64MHz or 96MHz etc. from chip transceiver, central processing unit and memory.
And based on the design requirement for being able to achieve different power consumption mode, each functional module can be in different clock domains；For example chip is set
In meter frequently with, make power supervisor work in relatively low clock domain, such as 32KHz；It is by the difference of work clock
It can control the state of each functional module, so that chip be made to be in different power consumption mode.
In current electronics smoke product, operating mode be in order to meet carry out smoking event and will in controller 23 it is related
High power consumption use state of necessary function module when being all turned on.Standby mode is when not smoking temporarily or wouldn't need smoking, to incite somebody to action
Necessary each functional module of smoking in controller 23 is selectively closed, and controller 23 is made to be in monitoring operation and can be timed meter
The low-power consumption use state that number wakes up, tally function relevant module in part is in the open state under the standby mode, such as
House dog, when base timer etc.；The timer counter carried when standby mode can be designed by chip wakes up software program and carries out
It wakes up, hence into operating mode.Shutdown mode is the use of extremely low power dissipation when closing the repertoire module of controller 23

Row timing wake-up, timing wake-up include:
S51 detects whether be connected with atomizer 10 on current power device 20；If so, entering step S52；If it is not, then
Controller 23 is adjusted to shutdown mode by standby mode；
S52, control gas flow transducer 22 detect current atomizer 10 with the presence or absence of smoking air-flow；If so, return step
Controller 23 is adjusted to operating mode by S20, is opened relevant each functional module of smoking and is smoked；If it is not, then entering next
Secondary wake-up.
The complete power consumption control process step of the electronic cigarette of above embodiments, be with user open power supply boot up it is dynamic
Make or starts to execute by the opportunity that exterior interrupt carries out interrupt processing；In implementation, further according to the transformation and movement of program
Detection, the power consumption mode of controller is adjusted and be controlled, thus realize reduce power consumption purpose.
The reset of step S10 be the boot action for making method and user, interrupt processing movement be consistent, be switched on user
Using/and the state that resets into control program executes power consumption control step after interrupting.Certainly resetting most importantly makes
The hardware and software relevant to tobacco control such as controller 23 restores to original state.
Subsequent step S20 and step S30 in a control program first setting operating mode as beginning state, it is subsequent according to
Whether family smokes with whether atomizer 10 connects online, by the corresponding standby mode and shutdown mould being adjusted as low-power consumption of mode
Formula.And acting depending on the user's operation, standby mode is timed wake-up and passes through exterior interrupt to shutdown mode
Or the interrupt signal of setting carries out interruption wake-up.Wherein, it is generated by the smoking movement that gas flow transducer 22 detects user
Air-flow changes and then judges whether to smoke, and is to compare preferred embodiment；It can also use and pass through in other deformation implementations
Baroceptor detection user aspirates the negative pressure generated to judge whether to smoke, or is in response to the mechanical microswitch of air-flow
The modes such as triggering act to monitor the smoking of user.
Step S30 and step S4 passes through respectively simultaneously detects whether smoking and atomizer 10 connect, and adjusts separately
Controller 23 is to standby or shutdown mode.Or in variation control, use smoking gas ought can be not detected in step s 30
When stream, first adjusts controller 23 and enter standby mode；Whether subsequent step S40 connects according to atomizer 10, then standby mode
Controller 23 carry out state adjustment, selection keeps standby or further adjust to shutdown.

Voltage, Vadc are the sampled voltage of chip, can be detected power supply dress by calculating the atomizer 10 obtained access both ends resistance value Rat
Whether set has atomizer 10 on 20.
Further, step S50 timing wake-up step, which is used, executes step S51 and step S52 according to certain frequency circulation,
When there are wake-up of the triggering to controller 23 when the suction action of user for determination in cyclic process；Wherein,
Each circulation of step S50 is all made of detect whether be connected with atomizer 10 on power supply device 20 again before starting,
Its one side is the connection shape by the connection status of atomizer 10 in the circulation and other steps or atomizer 10 in the process
State is isolated, and guarantees that the triggering of controller 23 is only controlled by 10 connection status of atomizer in the circulation；On the other hand the step
S50 is in different software modules when being executed from step S10~S40, and step S10~S40 is the master in controller 23
Executed in control program, step S50 be configured in the included house dog of controller 23, when base timer isochronon functional module in hold
Row.
In embodiment in the entire cyclic process of the wake operation of step S50, only when atomizer 10 is by from power supply device
20 when pulling out and returning to operating mode and smoked, and just exits circulation.Circulation starts all to detect primary atomization device 10 each time
Whether it is connected on power supply device 20, smoking detection is entered if the presence in connection, passes through conditional control
Gas flow transducer 22 achievees the purpose that most preferably to reduce power consumption with this.
In an implementation, the frequency of implementation and the time of timing wake-up can bases for the timing wake-up step of above step S50
