Step S100 includes the following contents in one of the embodiments, is please referred to Fig.4.
Step S110. detects voltage to the load 300 of atomization circuit input corresponding with the pattern of lighting a cigarette first.
Wherein, when the load of atomization circuit 300 is atomizer, suction function may be implemented in atomization circuit, is atomized at this time
The operating mode of circuit is the pattern that lights a cigarette.To mist when first detection voltage can work normally for atomization circuit under the pattern of lighting a cigarette
Change the voltage of device input.Specifically, the first detection voltage can be between 2.5V to 3.5V, for example, 3V.Therefore, apply the first inspection
Survey voltage, in order to which whether the load 300 for detecting atomization circuit is atomizer.
Operating voltage when being charged less than external equipment due to the operating voltage of atomizer, in other words, atomization circuit
Output voltage under the pattern of lighting a cigarette is less than output voltage of the atomization circuit under charge mode, therefore the embodiment of the present invention is first
Whether be atomizer, can improve safety if detecting voltage by first come the load 300 for detecting atomization circuit.
Step S120. receives the first current value of the load 300 of atomization circuit under the first detection voltage.
After exporting the first detection voltage, current detection circuit 200 can detect the of the load 300 for flowing into atomization circuit
One current value, and the first current value is sent to control circuit 100.
If the first current values of step S130. are in the first current range, judge that the load 300 of atomization circuit is atomization
Device.
Wherein, the first current range is that the current range of atomizer is flowed through when being atomized normal operation circuit under the pattern of lighting a cigarette.
Since the first detection voltage is corresponding with the pattern of lighting a cigarette, only when the load of atomization circuit 300 is atomizer, atomization circuit
Just can be with normal operation, at this moment the first current value is in the first current range;And if the load 300 of atomization circuit sets for outside
Standby or atomization circuit is in open-circuit condition, and atomization circuit is then unable to operate normally, and at this moment the first current value is in the first electric current model
Except enclosing.
Specifically, the first current range can be more than zero.In other words, after being applied with the first detection voltage, if sentenced
Disconnected first current value is more than zero, and representing output loop, there are electric currents, at this moment then can be determined that the load 300 of atomization circuit is atomization
Device;If it is determined that the first current value is zero, representing output loop does not have electric current, at this moment then can be determined that the load of atomization circuit
300 be external equipment or zero load.
Step S130 includes the following contents in one of the embodiments, please refers to Fig. 5.
Step S131. judges whether the first current value is in the first current range, if so, thening follow the steps S132;Otherwise,
Execute step S133.
In the embodiment of the present invention, apply first detection voltage, in order to detect atomization circuit load 300 whether be
Atomizer, if it is not, then continuing to other voltages, whether the load 300 to detect atomization circuit is external equipment or mist
Change circuit and is in open-circuit condition.
The load 300 of step S132. judgement atomization circuits is atomizer.
Step S133. adjusts the voltage of the output of the load 300 to atomization circuit, and until reaches corresponding with charge mode
Second detection voltage.
Wherein, the second detection voltage be atomization circuit when can be worked normally under charge mode by adapter to outside
The voltage of equipment input.Specifically, which can be:Increase the voltage that the load 300 to atomization circuit exports, and until reaches
To the second detection voltage corresponding with charge mode.Second detection voltage can be between 4.5V to 5.5V, for example, 5V.Therefore,
Apply the second detection voltage, in order to which whether the load 300 for detecting atomization circuit is external equipment.
Step S134. receives the second current value of the load 300 of atomization circuit under the second detection voltage.
After exporting the second detection voltage, current detection circuit 200 can detect the of the load 300 for flowing into atomization circuit
Two current values, and the second current value is sent to control circuit 100.
If the second current values of step S135. are in the second current range, judge that the load 300 of atomization circuit sets for outside
It is standby.
Wherein, the second current range is that the electric current model of external equipment is flowed into when being atomized normal operation circuit under charge mode
It encloses.Since the second detection voltage is corresponding with charge mode, only when the load of atomization circuit 300 is external equipment, mist
Changing circuit just can be with normal operation, and at this moment the second current value is in the second current range;And if the load 300 of atomization circuit is
Atomizer or atomization circuit are in open-circuit condition, and atomization circuit is then unable to operate normally, and at this moment the second current value is in the second electricity
It flows except range.
Specifically, if the external equipment being connect with adapter is mobile phone, the second current range can be for 500mA extremely
Current range between 1000mA.At this moment, after being applied with the second detection voltage, if it is determined that the second current value is between 500mA
It is mobile phone to the load 300 that between 1000mA, then can be determined that atomization circuit.
Specifically, step S135 includes:Judge whether the second current value is more than the second threshold, if so, judgement mist
The load 300 for changing circuit is external equipment;Otherwise, if the second current value is zero, judge that atomization circuit is in open-circuit condition.
Wherein, atomization circuit is in open-circuit condition, and in other words the interface of atomization circuit does not connect any load.Therefore,
The embodiment of the present invention can identify whether the load 300 of atomization circuit is that atomizer, outside are set respectively by above-mentioned realization method
It is standby or unloaded.
In one of the embodiments, before step S100, above-mentioned atomization circuit control method further includes the following contents:
Judge whether to receive the operation signal for switching working mode, if so, being switched to atomization circuit according to the operation signal
The corresponding operating mode of the operation signal;Otherwise, step S100 is executed.
Wherein, can be that control circuit 100 is sent to by interactive device 500 for the operation signal of switching working mode
Signal.Therefore, atomization circuit control method provided in an embodiment of the present invention can both cut atomization circuit according to the wish of user
The desired operating mode of user is shifted to, and can voluntarily identify the load 300 of atomization circuit, and is switched to negative with atomization circuit
Carry 300 corresponding operating modes.
