1. An electronic cigarette preheating control method, comprising setting preheating parameters and a preheating routine in a microcontroller MCU arranged in the electronic cigarette,
wherein the preheating parameters at least include preset temperature value, and preset heating time or preset target temperature value,
wherein the electronic cigarette is provided with a preheating button, the preheating button is configured to, after the electronic cigarette is turned on, activate the preheating routine when the preheating button is pressed, and deactivate the preheating routine by means of the microcontroller MCU when the preheating button is pressed again such that the heating device is controlled to not preheat or stop preheating, and
wherein the preheating routine comprises:
detecting real-time temperature value by means of a temperature detection unit arranged in the electronic cigarette;
by means of the microcontroller MCU, comparing the real-time temperature value with the preset temperature value, and determining whether preheating of cigarette liquid stored inside a liquid storage chamber is required or not, if no, directly entering an available stand-by state of the electronic cigarette;
if yes, controlling a heating device arranged in the electronic cigarette by means of the microcontroller MCU to perform preheating for the preset heating time or until the preset target temperature value is reached, and then ending the preheating and entering the available stand-by state of the electronic cigarette; wherein, the temperature detection unit is configured to detect temperature by detecting a resistance value of a thermistor heating coil of the heating device to calculate the real-time temperature value,
wherein the preheating routine further comprises,
controlling an LED indicator light arranged on the electronic cigarette by means of the microcontroller MCU to emit light for warning when the microcontroller MCU determines that the preheating is required, and controlling a vibrator arranged on the electronic cigarette by means of the microcontroller MCU to provide vibration for warning when the preheating is finished.
