9. itch stopping apparatus according to claim 1-8, which is characterized in that the itch stopping apparatus uses multi-temperature zone gradient-controllable The method of heating is heated and is kept temperature constant, and the method for the multi-temperature zone gradient-controllable heating specifically includes following step It is rapid:
(1) main control chip MCU generates pulse-width modulation waveform PWM, starting heating;
(2) the main control chip MCU obtains heating starting signal and temperature gear signal, and segments pulse-width modulation waveform PWM tune Save gear;
(3) real time temperature of the main control chip MCU HEATER FOR MEASURING part, and according to the temperature where the real time temperature of heating device The last temperature value for spending inter-area modes and main control chip MCU measurement, adjusts the duty of the pulse-width modulation waveform PWM of output Than;Until reaching the set temperature of temperature gear, then the temperature is kept;
Main control chip MCU described in S31 obtains cell voltage, and corrects heating power coefficient;
Parameter needed for S32 obtains present real-time temperature and temperature rise adjustment;
S33 adjusts the duty of pulse-width modulation waveform PWM according to parameter needed for the real time temperature obtained in S32 and temperature rise adjustment Than then judging temperature at this time;
If the temperature of S34 at this time greater than 37 DEG C of preheating temperature, judges whether temperature at this time is greater than the setting temperature of temperature gear 45 ~ 50 DEG C of degree;If temperature at this time is more than or equal to 45 ~ 50 DEG C of set temperature of temperature gear, again by soaking zone PID arithmetic Duty ratio is set, and keeps temperature at this time;
If the temperature in S35 step S34 at this time is greater than 37 DEG C of preheating temperature and is less than 45 ~ 50 DEG C of set temperature of temperature gear When, then it runs constant temperature and rises section PID arithmetic, then duty ratio is set, until temperature at this time is greater than the temperature of temperature gear setting;
If the temperature in S36 step S34 at this time is less than 37 DEG C of preheating temperature, by the end setting duty ratio that is rapidly heated, and follow Ring step S32 to step S35 is greater than 45 ~ 50 DEG C of set temperature of temperature gear up to temperature at this time;
(4) judge whether preset whole heating time reaches, terminate to heat if reaching;If not reaching, default inspection is judged The testing temperature time whether arrival, if reach, detect current real time temperature and update current real time temperature, further according to more New current real time temperature, circulation step (3);If not reaching, default detection temperature-time is waited to reach, then detect current Real time temperature.
10. itch stopping apparatus according to claim 9, which is characterized in that preset entirety heating time is in the step (4) 20 ~ 600 seconds;The default detection temperature-time is 1 ~ 5 second.
