in this example, with the development of society and the progress of human beings, tobacco as a consumer product harmful to human body is gradually replaced with a health article having the same function. The capacitive sensor in the electronic cigarette is a main component in the electronic cigarette, when a smoker draws the electronic cigarette, the airflow of smoking can drive the vibrating diaphragm to vibrate, so that the capacitive sensor in the electronic cigarette senses the airflow change, and the voltage value corresponding to the heating wire of the electronic cigarette is determined according to the airflow change.
For people who smoke, different people have different habits. For example, some people like to pay little smoke, only feel smoking, and general electronic cigarette capacitive sensors are satisfactory for such smokers. While some people like to pay more attention to smoke so as to create a smoke-surrounding environment during smoking, so that more smoke is required to be generated by the electronic cigarette, and a capacitor sensor for the electronic cigarette is required to generate a larger induction signal so as to control a heating wire of the electronic cigarette to be continuously heated, and the temperature in a cavity of the electronic cigarette is continuously increased. However, the capacitance sensor can cause drift of the temperature coefficient of the capacitance and change of capacitance parameters due to the change of the ambient temperature, so that the capacitance value of the sensor is different from the originally designed capacitance value, and the damage of the capacitance sensor is easy to cause, therefore, the temperature in the cavity of the electronic cigarette needs to be restored to a normal value, and the capacitance sensor can maintain stable operation. Wherein the capacitance temperature coefficient (temperature coefficient of capacitance) is the ratio of the value of the change in capacitance to the nominal capacitance at a given temperature interval for every 1 ℃ change in temperature. The capacitance temperature coefficient expression is:
in the formula: t (T) KC For the temperature coefficient of capacitance, C is the nominal capacitance at a given temperature, Δc represents the difference between the capacitance values C1, C2 measured at room temperature t1 and the limit temperature t 2.Δt represents the difference between the room temperature t1 and the limit temperature t2, and Δc is the change value of the capacitance when the temperature changes Δt.

Specifically, a voltage value is preset as a threshold voltage, wherein the threshold voltage is determined according to the actual performance of the capacitive sensor, and when the voltage value corresponding to the heating wire is greater than or equal to the threshold voltage, the temperature compensation circuit is started.
Further, after the temperature compensation circuit, the voltage value of the heating wire is continuously reduced through the temperature compensation circuit, so that the temperature of the cavity of the electronic cigarette is restored to a normal range value, and when the voltage value corresponding to the heating wire is smaller than the threshold voltage and the temperature in the cavity of the electronic cigarette is smaller than the preset temperature, the temperature compensation circuit is turned off.

Fig. 4 is a transistor temperature compensation circuit, namely, the first diode group in the diode compensation circuit is replaced by a transistor group, which functions the same, so that the description about the transistor compensation circuit is omitted.
Specifically, the temperature in the cavity of the electronic cigarette is obtained, and a voltage adjustment value is determined according to the temperature in the cavity and the temperature compensation circuit. When the temperature in the cavity of the electronic cigarette is less than or equal to the threshold temperature, the temperature compensation circuit does not need to work, so that the voltage adjustment value at the moment is equal to a preset value, and the preset value can be 0 or a smaller voltage value; when the temperature in the cavity of the electronic cigarette is larger than the threshold temperature, the temperature compensation circuit is utilized to obtain the voltage adjustment value.
