Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Temperature-controlled atomizing device is the atomizer using temperature control mode, and when work wants stability contorting temperature, makes the resistance value of atomizer
Moment is maintained in the corresponding Standard resistance range of preset temperature.Generally, when the resistance value of atomizer is not in the corresponding resistance value of preset temperature
When in range, the resistance value of atomizer can be made to keep in the corresponding Standard resistance range of preset temperature by adjusting the voltage of atomizer.Such as
It is voltage change comparison of wave shape figure of the temperature-controlled atomizing device in temperature-controlled atomizing device when having tobacco tar and smokeless oil shown in Fig. 1.Atomization
When device works, tobacco tar is atomized by converting electrical energy into thermal energy realization, initial stage of operation, atomizer resistance value does not reach pre-
If atomizer voltage constantly increases when temperature corresponding resistance value, to increase atomizer temperature, when atomizer resistance value reaches default temperature
After spending corresponding resistance value, the operating voltage of atomizer is constantly regulate so that atomizer maintains preset temperature.When there is tobacco tar, according to
Law of conservation of energy, since atomization smoke oil can take away heat, the cooling of atomizer heating wire needs to increase voltage, to increase electric energy
The output of thermal energy is continuously replenished, also, in the process, it is corresponding that real-time detection judges whether atomizer has reached preset temperature
Resistance value reduce voltage output if having reached the corresponding resistance value of preset temperature, to maintain preset temperature.But due to
It has tobacco tar atomization and takes away heat, therefore, voltage fall very little forms the process of a dynamic equilibrium, occurs in Fig. 1
The more stable voltage oscillogram in side.
And when there is no tobacco tar, according to law of conservation of energy, due to not having tobacco tar atomization to take away heat, heating wire will not be stood
Dissipated heat is carved, therefore atomizer temperature can be ramping up, and judge whether to have reached the corresponding resistance value of preset temperature at this time, such as
Fruit has reached the corresponding resistance value of preset temperature, in order to maintain preset temperature, reduces voltage output at once, and due to there is no tobacco tar
Heat is taken away, so needing constantly to turn down voltage, the output of obtained thermal energy is turned by electric energy to reduce, since voltage is constantly adjusted
Low, so that atomizer voltage declines by a big margin, voltage waveform can acutely decline at once.After dropping to a certain degree, and send out
Existing atomizer cools, and increases voltage again, increases and finds that temperature reaches assigned temperature again for a moment, and starts to reduce voltage,
And big ups and downs are understood again, it may appear that more violent shake voltage oscillogram is planted in lower section in Fig. 1.
It can be seen from voltage waveform variation in Fig. 1 when there is tobacco tar, the operating voltage variation of atomizer will not continue
Decline, voltage change amplitude very little, waveform are steady.And when there is dry combustion method, the voltage change of atomizer can continue to decline, and
It declines by a big margin, fluctuation is violent.Therefore, it may determine that atomizer by detecting the variation severe degree judgement of atomizer voltage
Whether dry combustion method is occurred.
As shown in Fig. 2, in a kind of electronic atomization device atomizer dry combustion method judgment method, comprising the following steps:
Step 102: reading atomizer present operating voltage.
Specifically, atomizer needs constantly to adjust voltage output during the work time to maintain atomizer in preset temperature model
Enclose interior operation.In the atomizer course of work, real-time detection atomizer operating voltage reads atomizer present operating voltage.
Step 104: judging whether atomizer present operating voltage reaches default dry combustion method voltage threshold, when the current work of atomizer
When reaching default dry combustion method voltage threshold as voltage, starting atomizer dry combustion method protection.
Specifically, present operating voltage is compared with default dry combustion method voltage threshold, atomizer work at present electricity is judged
Whether pressure reaches default dry combustion method voltage threshold, when atomizer present operating voltage reaches default dry combustion method voltage threshold, is then atomized
There is dry combustion method, starting atomizer dry combustion method protection in device.Conversely, when atomizer present operating voltage does not reach default dry combustion method voltage threshold
When value, atomizer is working properly, continues to test atomizer operating voltage, does not do other processing.
By the operating voltage change procedure explanation of the above atomizer it is found that when atomizer voltage declines, atomizer
It is possible that there is dry combustion method.Therefore, in one embodiment, presetting dry combustion method voltage threshold is default operating voltage minimum value, again
Have in one embodiment, preset dry combustion method voltage threshold be predeterminated voltage amplitude threshold, therefore, when atomizer voltage drop to it is default
When operating voltage minimum value or when voltage fall reaches predeterminated voltage amplitude threshold, there is dry combustion method, starting atomization in atomizer
Device dry combustion method protection.

The shortcomings that sentencing.Also, the judgment method of atomizer dry combustion method, which need to only detect, in above-mentioned electronic atomization device judges voltage change situation
, not having to worry that the atomizer working time is too long and overheats and the case where erroneous judgement dry combustion method occurs, the accuracy rate of dry combustion method judgement is high, and
It is simple to operate.
In one embodiment, presetting dry combustion method voltage threshold is default operating voltage minimum value.Step 104 includes: judgement
Whether atomizer present operating voltage is less than or equal to default operating voltage minimum value, if atomizer present operating voltage be less than or
Equal to default operating voltage minimum value, then start atomizer dry combustion method protection.
Specifically, choosing the default operating voltage minimum value of atomizer in advance in the present embodiment, it is minimum to preset operating voltage
Value is voltage value when dry combustion method occurs for atomizer.If the present operating voltage of atomizer is greater than default operating voltage minimum value,
Then atomizer is working properly, continues to test atomizer operating voltage, without doing other processing.When the operating voltage of atomizer
Reach default operating voltage minimum value to be then atomized when that is, atomizer operating voltage is less than or equal to default atomizer operating voltage
There is dry combustion method in device, needs to start atomizer dry combustion method protection.Further, presetting operating voltage minimum value can be in atomizer work
Make the dynamic duty voltage minimum obtained under state, can also be the average value for taking several dynamic duty voltage minimums.One
As, different atomization core materials, corresponding default operating voltage minimum value would also vary from, for example, the default work of nickel

Operating voltage minimum value is specifically preset in the atomization core material setting of use.
In one embodiment, presetting dry combustion method voltage threshold is predeterminated voltage amplitude threshold.As shown in figure 3, step 104 is wrapped
It includes:
Step 1042: obtaining atomizer operating voltage maximum value, judge whether present operating voltage is greater than operating voltage most
Big value.
Specifically, atomizer operating voltage maximum value is collected maximum voltage value in the atomizer course of work.Pass through
The present operating voltage of atomizer is compared with the operating voltage maximum value of atomizer, it can be determined that the voltage of atomizer becomes
Change process, when atomizer voltage rise constantly increase when, illustrate that the corresponding resistance value of preset temperature has not been reached yet in atomizer, need after
It is continuous to increase atomizer voltage output, and operating voltage maximum value is constantly updated in the process.When atomizer voltage declines,
Then illustrate that atomizer has reached the corresponding resistance value of preset temperature, at this point, step 1044 is executed, by judging voltage drop low amplitude
Judge whether atomizer dry combustion method occurs.
In the present embodiment, when atomizer operating voltage maximum value is atomizer work, collected maximum in the course of work
Voltage value.In other embodiments, operating voltage maximum value can also be several atomizer dynamic duty electricity in a period of time
Press the average value of maximum value.
Step 1044: if present operating voltage is less than operating voltage maximum value, judging present operating voltage and default electricity
Press whether the sum of amplitude threshold is less than or equal to operating voltage maximum value.
Specifically, choosing predeterminated voltage amplitude threshold △ V in advance, predeterminated voltage amplitude threshold △ V is mist when dry combustion method occurs
The operating voltage fall threshold value for changing device, the most unskilled labourer after being reduced when being the operating voltage maximum value and generation dry combustion method of atomizer
Make the difference of voltage.Predeterminated voltage amplitude threshold △ V can be under the dynamic electric voltage amplitude obtained under atomizer working condition
Threshold value is dropped, can also be the average value of several dynamic electric voltage amplitude falling-threshold values.
Generally, different atomization core material, corresponding predeterminated voltage amplitude threshold △ V would also vary from, for example, nickel
Predeterminated voltage amplitude threshold △ Vni and stainless steel N316 predeterminated voltage amplitude threshold △ Vss difference with regard to obvious, it is real
Specific predeterminated voltage amplitude threshold is arranged according to the atomization core material specifically used in the application of border.
If atomizer present operating voltage is less than its operating voltage maximum value, atomizer voltage declines, at this point,
Judge the voltage fall of atomizer to judge whether atomizer dry combustion method occurs.If present operating voltage and predeterminated voltage width
Spend whether the sum of threshold value is less than or equal to operating voltage maximum value, that is to say, that the voltage fall of atomizer has been more than default
Voltage amplitude threshold value executes step 1046 then dry combustion method occurs in atomizer.If the present operating voltage of atomizer and default electricity
The sum of amplitude threshold is pressed to be greater than the operating voltage maximum value of atomizer, that is to say, that the voltage fall of atomizer is default
In voltage amplitude threshold range, then atomizer is working properly, continues to test atomizer operating voltage, without doing other places
Reason.
Step 1046: if the sum of present operating voltage and predeterminated voltage amplitude threshold are less than or equal to operating voltage maximum value,
Then start atomizer dry combustion method protection.
In one embodiment, after step 1042 further include: if present operating voltage is greater than operating voltage maximum value,
Update operating voltage maximum value is present operating voltage.
In the present embodiment, when atomizer operating voltage maximum value is atomizer work, collected maximum in the course of work

If present operating voltage is greater than operating voltage maximum value, updating operating voltage maximum value is present operating voltage；If current work
Make voltage less than operating voltage maximum value, then operating voltage maximum value remains unchanged.
Specifically, the operating voltage maximum value Vmax of atomizer is compared by constantly real time monitoring, i.e., work at present electricity
Pressure Vcurrent is obtained compared with operating voltage maximum value Vmax, specific:
As Vcurrent > Vmax, then Vmax=Vcurrent；
It as Vcurrent < Vmax, is then not processed, Vmax value is constant.

In range.Whether in the corresponding Standard resistance range of preset temperature judge whether atomizer is pre- especially by the resistance value for checking atomizer
If work in temperature range.It, can be by adjusting atomization when the resistance value of atomizer is not in the corresponding Standard resistance range of preset temperature
The voltage of device keeps the resistance value of atomizer in the corresponding Standard resistance range of preset temperature.Specifically, when atomizer does not reach pre-
If when the corresponding resistance value of temperature, the operating voltage for increasing atomizer increases electric energy input, converted with being continuously replenished by electric energy
The thermal energy arrived increases thermal energy output, atomizer is made to reach the corresponding resistance value of preset temperature.It is corresponded to when atomizer reaches preset temperature
Resistance value after, need to maintain the operating temperature of atomizer, therefore, the operating voltage at this time needing to reduce atomizer reduces electric energy
Input makes atomizer maintain preset temperature to reduce the output for turning obtained thermal energy by electric energy.
