Detailed description of the invention
In order to solve user in prior art can not experience completely smoke true time smog taste and the defect that changes with smoking dynamics of amount of smoke, innovative point of the present utility model is, heavily can take out according to user's reality and, the airflow signal gently taken out and preset value compare, corresponding unlatching is connected to the switch element of different heating element, control the tobacco tar in the different oil storage part of heating element heats corresponding to this switch element, to reach the object that smoking dynamics changes smog taste and amount of smoke.
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and describe detailed description of the invention of the present utility model in detail.
As shown in Figure 1, a kind of control circuit, for controlling electronic cigarette, it comprises at least one pneumatic sensor 10, control module 20, at least two heating element heaters 30, at least two switch elements 40 and supply module 50.The control end of these at least two switch elements 40, pneumatic sensor 10 and supply module 50 are connected with this control module 20 respectively.Each switch element 40 is connected between each heating element heater 30 and supply module 50 respectively correspondingly.
Pneumatic sensor 10 sucks the airflow signal in electronic cigarette at every turn for gathering and airflow signal is sent to control module 20, control module 20 is for comparing each airflow signal and preset value, and select to send Continuity signal to the switch element of at least two switch elements 40 40 according to comparative result, switch element 40 heats to make corresponding heating element heater 30 for conducting after receiving Continuity signal, and heating element heater 30 is atomized to make it for the tobacco tar heated in corresponding oil storage part.The number of switch element and heating element heater is 3 in the present embodiment.The number of pneumatic sensor is 1.Switch element 40 can select conventional on-off circuit.Certainly, in other embodiments, the multiple switch elements 40 in described switch element 40 can simultaneously conducting, or all switch element also can conducting simultaneously, to realize the object automatically recalling multiple taste and change amount of smoke.Resistance value in described heating element heater 30 can be identical, also can be different, and it is arranged as required, in this no limit.Such as, in the present embodiment, the resistance value between described heating element heater 30 is different, and corresponding different oil storage parts.
This control circuit controls electronic cigarette and makes user generate heat to reach the taste of corresponding adjustment smoking to the heating element heater 30 controlled in corresponding oil storage part by adjusting each dynamics of smoking, described amount of smoke also can adjust according to smoking dynamics automatically, thus can improve Consumer's Experience, make this electronic cigarette more close to true cigarette; In addition, the smoker that smoking dynamics is different with smoking taste can realize a shared electronic cigarette, and it is inconvenient to carry convenience in the environment of more article in out on tours etc. comparatively obvious, brings comparatively convenience especially to the family with many people smoking.
In a first embodiment, this control module 20 adopts microprocessor, such as, model can be adopted to be the chip of MSP430F5529 or SN8P2711.As shown in Figure 2, this microprocessor comprises AD conversion unit 21, memory cell 22, comparing unit 23 and control unit 24.Comparing unit 23 is connected with pneumatic sensor 10 and control unit 24 respectively, and control unit 24 is connected with at least two switch elements 40 respectively, and memory cell 22 is connected with comparing unit 23, and AD conversion unit 21 is connected with comparing unit 23.
AD conversion unit 21 is for being converted to data signal by analog signal, memory cell 22 is for storing at least two preset values pre-set, comparing unit 23 is for comparing the peak value and each preset value that are converted to the airflow signal after data signal, select the maximum preset value of the peak value being less than this airflow signal at least two preset values, and sending a compare result signal to control unit 24 according to this maximum preset value, control unit 24 is selected to send Continuity signal to the switch element of at least two switch elements 40 40 according to compare result signal.
Understandably, this microprocessor can also comprise a timing unit 25, this timing unit 25 is connected with control unit 24, control unit 24 sends a triggering signal to this timing unit 25 while transmission Continuity signal is to switch element 40, timing unit 25 starts timing after receiving triggering signal, and transmission feeds back signal to control unit 24 after the timing scheduled time, control unit 24 sends shutdown signal according to this feedback signal and is in the switch element 40 of conducting state to this, close after this switch element 40 being in conducting state receives shutdown signal and make corresponding heating element heater 30 stop heating.
The ON time of this timing unit 25 corresponding switch element 40 by the setting scheduled time thus when controlling each smoking, and then amount of smoke when more accurately controlling each smoking.Further, after predetermined hold-time, automatically close this switch element 24 can also save tobacco tar and electric energy, in order to avoid cause unnecessary waste.Such as this scheduled time can be 2 seconds, 3 seconds or 4 seconds etc., and corresponding ON time is also 2 seconds, 3 seconds or 4 seconds.
When this comparing unit 23 receives another airflow signal within this scheduled time, and produce a compare result signal and pass to control unit 24, when that is to say that the interval receiving airflow signal for twice is less than the scheduled time of setting in timing unit 25:
If it is identical with previous compare result signal to receive compare result signal after this, control unit 24 sends a triggering signal to timing unit 25, reset after this timing unit 25 receives this triggering signal, and restart timing, and transmission feeds back signal to this control unit 24 after the timing scheduled time, control unit 24 sends shutdown signal again after receiving feedback signal makes it close to the switch element 40 being in conducting state.
If the compare result signal received after this is different from previous compare result signal, control unit 24 sends a shutdown signal makes it close to the switch element 40 being in conducting state, sends a Continuity signal simultaneously and makes its conducting to the switch element 40 corresponding with the compare result signal received after this.And send a triggering signal to timing unit 25, this timing unit 25 resets and restarts timing, send one after the timing scheduled time and feed back signal to control unit 24, control unit 24 sends shutdown signal makes it close to the switch element 40 being in conducting state.
