MCU detects foot.Here first and second divider resistance R7, R8 settings are provided for detecting foot detection tobacco rod battery capacity for MCU
Voltage division signal.In addition, showing that the resistance value of the first and second divider resistance R7 and R8 is 10K in Fig. 4.In fact, first and second
The resistance value of divider resistance R7 and R8 can be identical, can also be different.They general resistance value is selected according to concrete application situation
It is selected as 10K or more, to reduce quiescent dissipation.
In addition it as shown in figure 4, cigarette case MCU is also connected with charge power supply management circuit, is exported with controlling power circuit.
The process that cigarette case MCU controls are the charging of tobacco rod battery is further described below.
As previously mentioned, when tobacco rod 4 is inserted into cigarette case chamber 22, corresponding aforementioned five contacts engage, and are produced through the contacts VDD
Raw electric signal passes to cigarette case microcontroller, is detected to the electricity of tobacco rod battery 44 by MCU detection feet to open.
And about MCU detect foot, it need to be noted that be：
Known tobacco rod battery capacity and tobacco rod cell voltage direct proportionality.Such as：Tobacco rod battery is 3.3V or more
When, it may be determined that the battery capacity of tobacco rod is more than 80%, it is known that tobacco rod cell voltage is about 4.2 volts；
The voltage of-MCU detection feet can follow the variation of cell voltage and linear change, relational expression are as follows：
MCU detects voltage=tobacco rod cell voltage x (R8/R7+R8) 1 of foot)
Wherein R7, R8 indicate the first and second respective resistance values of divider resistance R7, R8 respectively, and its resistance value is commonly known
's；
Cigarette case MCU can directly detect the voltage of MCU detection feet by internal or external A/D converter；
Foot voltage is detected thus according to the MCU detected, then can be inferred that whether tobacco rod battery needs to charge；
Communication process between cigarette case and tobacco rod is carried out by the two contacts SDA, SCL.
More specifically, when tobacco rod be inserted into cigarette case when, tobacco rod MCU by its respective pins using SDA, SCL line via SDA,
The contacts SCL send the data for inserting tobacco rod to cigarette case MCU, to start the MCU detection feet using cigarette case MCU to tobacco rod battery
The detection of electricity.
Definitely, cigarette case MCU directly detects that MCU detects the electricity inputted at foot by internal or external A/D converter
Pressure, then passes through above-mentioned relation formula 1) tobacco rod cell voltage is calculated, cigarette case is then previously stored according to look-up table inquiry
Table (direct proportionality between the battery capacity and tobacco rod cell voltage of tobacco rod) in MCU and obtain tobacco rod battery capacity.
Then cigarette case MCU carries out relevant control according to the tobacco rod battery capacity result obtained：If tobacco rod battery is full
Electric then control is not turned on the power circuit of cigarette case and charges for tobacco rod battery；Conversely, then cigarette case MCU to tobacco rod MCU send out by for its
The instruction of charging, tobacco rod MCU are then passed through its respective pins and are received from cigarette case MCU via the contact SDA, SCL using SDA, SCL line
The instruction carries out the preceding preparation that charges so as to its control.Preparation refers to before the so-called relevant charging of tobacco rod：Tobacco rod MCU controls
Stop stops tobacco rod battery to heating device for electrical heating, nor responds other actions again, for example user is sent out by button
The dependent instruction sent such as selects and/or changes smoke pattern.This is because if tobacco rod is still working when considering to recharge
If, the service life for shortening tobacco rod can be damaged.It is noted here that so-called " full electricity " be not meant as tobacco rod battery capacity must
Right 100%, in fact, when tobacco rod battery capacity for example reaches between 80%-100%, then it is believed that the full electricity of tobacco rod battery.Thing
The suitable preset value of corresponding full electricity can be set in reality as the case may be.
Tobacco rod MCU then transmits it to cigarette case MCU via the contact SDA, SCL and is ready for the appropriate feedback that can be charged
Information, then cigarette case MCU controls are exported to tobacco rod battery as the cigarette case battery of power circuit and are charged, such as the cigarette case electricity in Fig. 4
Pond to electric power management circuit, the contacts VDD, arrive again shown in the VDD line of cigarette case battery.Obviously here, SDA and SCL is double
To circuit.
And in above process, the contacts RESET keep high level.When it becomes low level, tobacco rod MCU can reset.
And above-mentioned formula can be passed through it is clear that A/D converter directly measures the voltage at MCU detection feet as described above
1) tobacco rod cell voltage is calculated, acquisition tobacco rod battery capacity of then tabling look-up, this is all realized inside cigarette case MCU.And
