Time in D, atomizing component without tobacco juice or tobacco juice rareness, heating wire R dry combustion method, the temperature on its surface sharply rises, temperature sensor 81 senses that the temperature signal in atomization chamber is also sharply strengthened, in the present embodiment, in setting atomization chamber 3, threshold temperature is 210 DEG C, when exceeding this set point, chip U1 reads the temperature signal of FB end and judges that it changes, the chip U1 control HOT end-grain cutting metal-oxide-semiconductor M1 that breaks exports the power supply of heating wire R, then can not carry out smoking, the luminous indicating fault status of diode D2, the temperature of heating wire R then starts to reduce;
E, when the temperature of heating wire R be not yet reduced to setting threshold values 210 DEG C or atomizing component does not add tobacco juice time, even if user again smoking because connecting smoking interrupteur SW and after switching on power, by temperature sensor 81, U1 detects that temperature signal that FB holds is still abnormal and cuts off the electricity supply rapidly, the luminous indicating fault status of diode D2;
F, when the temperature of heating wire R be reduced to setting threshold values less than 210 DEG C and with the addition of tobacco juice time, heating wire R recovers normal temperature, when user's smoking, U1 connects heating wire R and power supply, heating wire proper atomisation tobacco juice, by temperature sensor, U1 detects that the temperature signal that FB holds is normal, power supply keeps connecting, diode D1 luminescence instruction normal condition.
Another temperature-controlled process of the utility model embodiment is: based on the above method, after U1 detects the temperature signal that FB holds, not compare judgement according to the threshold temperature 210 DEG C of setting, but judge according to the rate of temperature change of setting, such as design temperature rate of change is 40 DEG C/sec, when rate of temperature change exceedes this value, cut-out metal-oxide-semiconductor M1 exports the power supply of heating wire R by U1, then can not carry out smoking.
It should be noted that in above-mentioned steps A and step B, the connecting and disconnecting of smoking interrupteur SW, by Non-follow control, when user needs smoking, press shift knob, and smoking interrupteur SW is connected, and again presses shift knob, and smoking interrupteur SW disconnects; Also can realize in the mode of the inner built-in pressure sensor of electronic cigarette, when user needs smoking, be changed, automatically to control the break-make of smoking interrupteur SW by the pressure of pressure sensor detected electrons cigarette inside.In addition, the break-make of the utility model smoking interrupteur SW also realizes by other modes, herein without the need to repeating one by one.
Foregoing circuit structure of the present utility model and temperature-controlled process can realize the inner control to heating wire temperature of electronic cigarette very well, to well prevent at atomizing component without heating wire dry combustion method phenomenon during tobacco juice, solve that temperature is too high to be burnt out electronic cigarette and cause pernicious gas and smell of burning material to be inhaled into the problem of human body occurrence injury health.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model right change and modify, and all should belong to the covering scope of the utility model claim.
