Concrete, for example, whether the mode that adopts shell fragment to trigger detects atomizer 30 access battery bars, shell fragment circuits for triggering can be connected with microcontroller 200 with power supply interface 101.When having atomizer access power supply interface, shell fragment circuits for triggering send triggering signal to microcontroller 200.Microcontroller 200 is controlled the second wireless identity module 201 and is sent electromagnetic wave.If be arranged at the rfid interrogator chip that the second wireless identity module 301 is U2270B for model, microprocessor 200 can be enabled pin (CFE pin) to realize termination the second wireless identity module 201 transmission electromagnetic waves by controlling its carrier frequency.
In embodiment of the present utility model, acting as of Zener diode D2 prevents ripple, because when battery electric quantity has consumed, violent change can occur the voltage of battery, by diode D2, can prevent the violent ripple producing that changes of voltage now.
Should understand; what the microprocessor 200 in the utility model embodiment adopted is that model is the single-chip microcomputer of Sn8P2711B; but those skilled in the art, under enlightenment of the present utility model, adopt other single-chip microcomputers with identical function or MCU to realize function of the present utility model also within protection domain of the present utility model.And any electronic cigarette that comprises control circuit of the present utility model is also all within protection domain of the present utility model.
The method flow diagram that the battery pole pair atomizer that is the utility model embodiment referring to Fig. 5 is identified.The method comprises the following steps:
Step S101, the pre-stored identifying information of the first wireless identity module 301, and and described identifying information is sent to the second wireless identity module 201.
Concrete, when atomizer 30 enters the workspace of the second antenna 2011 of the second wireless identity module 201 of battery bar 20 while being connected with battery bar (be about to atomizer 30), the first antenna 3011 in built-in the first wireless identity module 301 of atomizer 30 receives the electromagnetic wave that the second built-in antenna 2011 of the second wireless identity module 201 sends, and by electromagnetic wave be converted to electric energy with drive the identifying information of 301 pairs of storages of the first wireless identity module encode and modulate after by the first antenna 3011, send.
Should understand, if the first wireless identification 201 is active module embedded therein, do not need to receive the electromagnetic wave of the second identification module 201, and can by its inner power module automatically drive the identifying information of 301 pairs of storages of the first wireless identity module encode and modulate after by the first antenna 3011, send.
Step S102, the second wireless identity module 201 receive after the described identifying information of described the first wireless identity module 301 transmissions, and the identifying information of described reception is sent to microprocessor 200.
Concrete, the second antenna 2011 of the second wireless identity module 201 receives the signal that comprises identifying information, and this signal is amplified, is sent to microprocessor 200 after the processing such as demodulation, decoding.
When the second antenna 2011 receives after identifying information, microprocessor 200 can be controlled the second wireless identity module 201 and stop sending electromagnetic wave, to stop the communication connection between the first wireless identity module 301 and the second wireless identity module 201.
Step S103, microprocessor 200 judge according to the identifying information receiving whether described atomizer 30 and battery bar 20 mate.
Concrete, microprocessor 200 compares the identifying information receiving and the information prestoring, and take and determines whether the identifying information receiving mates in prestored information, if coupling is judged as atomizer and battery bar coupling, otherwise be judged as, does not mate.
The method of the utility model embodiment also comprises: according to the judgment result displays information of microprocessor.
Concrete, microprocessor 200 can make that light emitting diode D1's is luminous to point out by controlling the voltage of the 5th pin.Concrete, can for example, by controlling luminous intensity or the luminance (glimmering, keep Chang Liang) of light emitting diode D1, come respectively to mating and not mating and point out.In addition, also can only when coupling, control light emitting diode D1 luminous, or it is luminous only when not mating, to control light emitting diode D1
The method of the utility model embodiment also comprises: when microprocessor judgment result is that coupling and microprocessor are while receiving the triggering signal of circuits for triggering, control power supply circuits conducting so that supplying cell provides supply voltage by described power supply circuits for described atomizer.
The electronic cigarette of the utility model embodiment has following advantage: battery bar can mate identification to connected atomizer, can prevent that electronic cigarette battery bar and non-designated atomizer are mixed takes use, the problem such as avoid consumer to use mixed breaking down while taking unmatched electronic cigarette, mouthfeel is abnormal, make electronic cigarette quality safety and reliability; And LED when electronic cigarette of the present utility model also has various duties or abnormality indication, the function such as display mode can customization, the voltage of output short circuit protection and apneusis protection, driver output is customizable.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, also can make a lot of forms, within these all belong to protection of the present utility model.
