本发明公开了一种温控防干烧电子烟的温度控制方法，通过该控制方法实现对电子烟内部发热体R的温度控制，防止了在无烟液时发热体R干烧而导致温度过高的问题，具体的，该方法包括以下的步骤：The invention discloses a temperature control method for temperature-controlled anti-dry burning electronic cigarette, and the temperature control of the internal heating element R of the electronic cigarette is realized by the control method, and the heating of the heating element R during the smokeless liquid is prevented, resulting in temperature overheating High problem, specifically, the method includes the following steps:

A、用户在没有吸烟时，温控防干烧电子烟的吸烟开关SW断开，电源切断，整个电路控制板断电不工作；A. When the user is not smoking, the smoking switch SW of the temperature-controlled anti-dry electronic cigarette is disconnected, the power is cut off, and the entire circuit control board is powered off;

When the smokeless liquid or the smoke liquid in the atomization assembly is scarce, the heating element R is dry, the temperature in the atomization chamber rises sharply, and the temperature signal sent by the temperature sensor to the heating element in the atomization chamber is also sharply strengthened.When the temperature of the atomization chamber exceeds the threshold set by U1, the chip U1 reads the temperature electrical signal of the FB terminal and judges that it changes.

B、当用户开始吸烟时，接通吸烟开关SW，控制芯片U1根据KEY1信号在HOT端发出控制信号，使得MOS管M1接通发热体R的电源，温度传感器感应雾化腔的温度，U1开始读取FB端的温度电信号；B. When the user starts smoking, the smoking switch SW is turned on, and the control chip U1 sends a control signal at the HOT end according to the KEY1 signal, so that the MOS tube M1 turns on the power of the heating element R, and the temperature sensor senses the temperature of the atomizing chamber, U1 starts. Reading the temperature electrical signal of the FB terminal;

C、雾化组件内有烟液时，发热体R则雾化烟液，发热体R传导给雾化腔的温度较为稳定，此过程中温度传感器能接收雾化腔中发热体发出的较为稳定的温度信号，芯片U1读取FB端的温度变化率低于设定的温度变化率，U1在HOT端发出的控制信号不变化，发热体R的电源继续接通，可以正常吸烟；C.

When the smokeless liquid or the smoke liquid in the atomization unit is scarce, the heating element R is dry, the temperature of the surface of the heating element rises sharply, and the temperature signal sent by the temperature sensor to the heating element in the atomizing chamber is also sharply strengthened.When the temperature change rate of the atomization chamber exceeds the temperature change rate set by U1, the chip U1 controls the HOT terminal to cut off the power output of the MOS tube M1 to the heating element R, and smoking cannot be performed, and the temperature of the atomization chamber starts to decrease;

E、当雾化腔的温度变化率尚未降低至设定阀值或雾化组件未添加烟液时，用户即使再次吸烟因接通吸烟开关SW而接通电源后，U1通过温度传感器检测到FB端的温度变化率仍高于设定的温度变化率而迅速切断电源；E. When the temperature change rate of the atomization chamber has not decreased to the set threshold or the atomization component is not added with the smoke liquid, the U1 detects the FB through the temperature sensor even if the user turns on the power again after turning on the smoking switch SW. The temperature change rate of the terminal is still higher than the set temperature change rate and the power supply is quickly cut off;

F、当雾化腔的温度变化率降低至设定阀值以下以及添加了烟液时，雾化腔恢复正常温度，当用户吸烟时U1接通发热体电源，发热体正常雾化烟液，U1通过温度传感器检测到FB端的温度变化率正常，电源保持接通。F. When the temperature change rate of the atomization chamber decreases below the set threshold and the smoke liquid is added, the atomization chamber returns to the normal temperature. When the user smokes, U1 turns on the heating body power supply, and the heating element normally atomizes the liquid smoke. U1 detects that the temperature change rate of the FB terminal is normal through the temperature sensor, and the power supply remains on.

结合上述图1、2、3、5所示，下面我们对本发明的此种温控防干烧电子烟的具体的工作过程进行描述，即该电子烟的温度控制方法包括以下的步骤：Referring to the above-mentioned Figures 1, 2, 3, and 5, we will describe the specific working process of the temperature-controlled anti-dry electronic cigarette of the present invention, that is, the temperature control method of the electronic cigarette includes the following steps:

A、用户在没有吸烟时，吸烟开关SW断开，电源5切断，整个电路控制板6断电不工作； A. When the user is not smoking, the smoking switch SW is disconnected, the power supply 5 is cut off, and the entire circuit control board 6 is powered off and does not work;

B、当用户开始吸烟时，接通吸烟开关SW，控制芯片U1根据KEY1信号在HOT端发出控制信号，使得MOS管M1接通发热丝R的电源，温度传感器81（即R9）感应到雾化腔3的温度，U1开始读取FB端的温度电信号，此时二极管D1发光；B. When the user starts smoking, the smoking switch SW is turned on, and the control chip U1 sends a control signal at the HOT end according to the KEY1 signal, so that the MOS tube M1 turns on the power of the heating wire R, and the temperature sensor 81 (ie, R9) senses the atomization. The temperature of the cavity 3, U1 begins to read the temperature electrical signal of the FB terminal, at which time the diode D1 emits light;

C、雾化组件内有烟液时，发热丝R则雾化烟液，发热丝传导给雾化腔3的温度较为稳定，此过程中温度传感器81能感应所述雾化腔3的较为稳定的温度信号，芯片U1读取FB端的温度电信号没有变化，U1在HOT端发出的控制信号不变化，可以正常吸烟，二极管D1继续发光指示正常状态；C. When there is smoke liquid in the atomization assembly, the heating wire R atomizes the smoke liquid, and the temperature of the heating wire to the atomization chamber 3 is relatively stable, and the temperature sensor 81 can sense the stability of the atomization chamber 3 in the process. The temperature signal, the chip U1 reads the temperature electrical signal of the FB terminal does not change, the control signal sent by the U1 at the HOT terminal does not change, can normally smoke, and the diode D1 continues to emit light to indicate a normal state;

D、雾化组件内无烟液或者烟液稀少时，发热丝R干烧，其表面的温度急剧上升，温度传感器81感应到雾化腔中的温度信号也急剧加强，在本实施例中，设定雾化腔3中阀值温度为210℃，超过该设定值时，芯片U1读取FB端的温度电信号并判断其发生变化，芯片U1控制HOT端切断MOS管M1对发热丝R的电源输出，则不能进行吸烟，二极管D2发光指示故障状态，发热丝R的温度则开始降低；D. When the smokeless liquid or the smoke liquid in the atomization assembly is scarce, the heating wire R is dry and the temperature of the surface thereof rises sharply, and the temperature signal sensed by the temperature sensor 81 in the atomization chamber is also sharply strengthened. In this embodiment, The threshold temperature in the atomization chamber 3 is set to 210 ° C. When the set value is exceeded, the chip U1 reads the temperature electrical signal of the FB terminal and judges that it changes. The chip U1 controls the HOT terminal to cut off the MOS tube M1 to the heating wire R. When the power is output, smoking cannot be performed, and the diode D2 emits light to indicate a fault state, and the temperature of the heating wire R starts to decrease;

E、当发热丝R的温度尚未降低至设定阀值210℃或雾化组件未添加烟液时，用户即使再次吸烟因接通吸烟开关SW而接通电源后，U1通过温度传感器81检测到FB端的温度电信号仍不正常而迅速切断电源，二极管D2发光指示故障状态；E. When the temperature of the heating wire R has not decreased to a set threshold of 210 ° C or the atomizing component is not added with smoke liquid, the user detects that the U1 is detected by the temperature sensor 81 even if the user turns on the power again after turning on the smoking switch SW. The temperature electrical signal at the FB terminal is still abnormal and the power supply is quickly cut off, and the diode D2 emits light to indicate a fault state;

F、当发热丝R的温度降低至设定阀值210℃以下以及添加了烟液时，发热丝R恢复正常温度，当用户吸烟时U1接通发热丝R与电源，发热丝正常雾化烟液，U1通过温度传感器检测到FB端的温度电信号正常，电源保持接通，二极管D1发光指示正常状态。F. When the temperature of the heating wire R drops below the set threshold of 210 ° C and the smoke liquid is added, the heating wire R returns to the normal temperature. When the user smokes, the U1 turns on the heating wire R and the power source, and the heating wire is normally atomized. Liquid, U1 detects that the temperature electrical signal of the FB terminal is normal through the temperature sensor, the power supply remains on, and the diode D1 emits light to indicate the normal state.

本发明实施例的另一温度控制方法是：在上述方法的基础上，U1检测到FB端的温度电信号以后，不是按照设定的温度阀值210℃来进行比较判断，而是按照设定的温度变化率来进行判断，例如设定温度变化率为40℃/秒，当温度变化率超过此值时，U1将切断MOS管M1对发热丝R的电源输出，则不能进行吸烟。Another temperature control method according to the embodiment of the present invention is: on the basis of the above method, after U1 detects the temperature electrical signal at the FB end, the comparison judgment is not performed according to the set temperature threshold 210 ° C, but is set according to the setting. The temperature change rate is determined, for example, the temperature change rate is set to 40 ° C / sec. When the temperature change rate exceeds this value, U1 will cut off the power output of the MOS tube M1 to the heating wire R, and smoking cannot be performed.

应当说明的是，在上述的步骤A和步骤B中，吸烟开关SW的接通与断开可通过手动控制，当用户需要吸烟时，按下开关按钮，吸烟开关SW接通，再次按下开关按钮，吸烟开关SW断开；也可在电子烟内部内置压力传感器的方式来实现，用户需要吸烟时，通过压力传感器检测电子烟内部的压力变化，以自动控制吸烟开关SW的通断。另外，本实用新型吸烟开关SW的通断也可通过其他方式实现，此处无需一一赘述。It should be noted that, in the above steps A and B, the turning on and off of the smoking switch SW can be manually controlled. When the user needs to smoke, the switch button is pressed, the smoking switch SW is turned on, and the switch is pressed again. The button and the smoking switch SW are disconnected; the pressure sensor can be built in the electronic cigarette. When the user needs to smoke, the pressure sensor detects the pressure change inside the electronic cigarette to automatically control the opening and closing of the smoking switch SW. In addition, the on/off of the smoking switch SW of the present invention can also be implemented by other means, and need not be described herein.

本发明的上述电路结构及温度控制方法能够很好实现电子烟内部对发热丝温度的控制，很好地防止了在雾化组件无烟液时发热丝干烧现象，解决了温度过高烧坏电子烟以及导致有害气体及焦味物质被吸入人体发生危害人体健康的问题。The above-mentioned circuit structure and temperature control method of the invention can well realize the control of the temperature of the heating wire inside the electronic cigarette, and the dry burning phenomenon of the heating wire in the smokeless liquid of the atomizing component is well prevented, and the overheating of the temperature is solved. E-cigarettes and problems that cause harmful gases and burnt substances to be inhaled into the human body and endanger human health.
