After the current temperature of the heating body in the target electronic cigarette is determined according to the current input current, the current temperature of the heating body in the target electronic cigarette is compared with a preset temperature threshold value, whether the current temperature needs to be adjusted or not is determined, the current temperature can be adjusted to be increased or decreased, if the current temperature does not need to be adjusted, the preset temperature threshold value can be a temperature value set according to actual use requirements, the target electronic cigarette can be maintained at the temperature all the time in the use process, the taste of a user when the user uses the electronic cigarette is kept consistent, and the best use experience is provided for the user. Specifically, when the current temperature is inconsistent with the preset temperature threshold, the temperature of the heating body needs to be adjusted, and when the current temperature is consistent with the preset temperature threshold, it is determined that the temperature of the heating body does not need to be adjusted. Therefore, the heating temperature of the electronic cigarette is accurately controlled, the temperature of the electronic cigarette is kept consistent with the temperature required by a user, and the reliability of the electronic cigarette in use is improved.

Therefore, after the current detection circuit based on the target electronic cigarette detects the current input current of the target electronic cigarette, the preset association relationship between the input current and the temperature of the heating body stored in the memory can be extracted through the MCU. Further, the temperature corresponding to the current input current can be searched according to the association relationship, and the temperature corresponding to the current input current is determined as the current temperature of the heating body in the target electronic cigarette.

Further, based on the first embodiment of the temperature control method of the electronic cigarette, a third embodiment of the temperature control method of the electronic cigarette is provided, and in the third embodiment, the step of performing temperature control on the heating body according to the relationship between the current temperature and a preset temperature threshold includes:
step S31, determining whether the current temperature is consistent with a preset temperature threshold value;
and step S32, if the current temperature is not consistent with the preset temperature threshold, adjusting the current temperature to be consistent with the preset temperature threshold.
After determining the current temperature of the heating body in the target electronic cigarette according to the current input current, the present embodiment may obtain a temperature threshold that is set by the user in advance according to the user demand, compare the current temperature with the preset temperature threshold, and determine whether the current temperature is consistent with the preset temperature threshold. In an embodiment, the difference operation may be performed on the current temperature and the preset temperature threshold, and if the difference operation result is zero, it is determined that the current temperature is consistent with the preset temperature threshold, and if the difference operation result is not zero, it is determined that the current temperature is not consistent with the preset temperature threshold. Further, if the current temperature is determined to be consistent with the preset temperature threshold, which indicates that the current temperature is the temperature expected by the user, the current temperature does not need to be adjusted; if the current temperature is determined to be inconsistent with the preset temperature threshold, it is determined that the current temperature is different from the temperature expected by the user, so that the current temperature needs to be adjusted, the adjusted temperature is the temperature expected by the user, the target electronic cigarette can be maintained at the expected temperature all the time in the using process of the user, the taste of the user using the electronic cigarette is guaranteed to be consistent, and the optimal use experience is provided for the user.
It can be understood that in this embodiment, when the current temperature is adjusted to make the adjusted temperature consistent with the preset temperature threshold, the input voltage may be adjusted by adjusting the duty ratio of the PWM signal, for example, if the current temperature needs to be raised, the duty ratio of the PWM signal is increased to increase the input voltage, so as to increase the current input power; and if the current temperature needs to be reduced, reducing the duty ratio of the PWM signal to reduce the input voltage, further reducing the current input power, further forming corresponding input power by the regulated input voltage, heating the heating body based on the new input power, and changing the current temperature of the heating body to be consistent with the preset temperature threshold value. The realization is to electron cigarette heating temperature's accurate control, makes the temperature of electron cigarette keep unanimous with the temperature that the user needs, improves the reliability when the electron cigarette uses.

And after a current difference value of the current input current and the input current corresponding to the preset temperature threshold is obtained, the current input voltage of the heater in the electronic cigarette is obtained, and the input power difference is calculated according to a power calculation formula by combining the current difference value and the current input voltage. And after the input power difference is calculated, compensating the current input power or reducing the current input power according to the input power difference, so that the temperature of the heating body heated according to the adjusted input power is consistent with a preset temperature threshold value. The realization is to electron cigarette heating temperature's accurate control, makes the temperature of electron cigarette keep unanimous with the temperature that the user needs, improves the reliability when the electron cigarette uses.
