Title:
ATOMIZATION DEVICE, HEATING CIRCUIT, METHOD, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/143035
Kind Code:
A1
Abstract:
An atomization device, a heating circuit, a method, and a readable storage medium. The heating circuit comprises a heating body resistor, an MCU, and a sampling resistor, and a resistance value of the sampling resistor is greater than a resistance value of the heating body resistor. The MCU controls a battery power supply to only supply power to the heating body resistor during a first time period of a PWM period. During a second time period of the PWM period, the MCU controls the battery power supply to supply power to the sampling resistor and the heating body resistor which are connected in series, respectively collects the voltage of the heating body resistor and the voltage of the sampling resistor, and calculates the resistance value of the heating body resistor according to the resistance value of the sampling resistor and the collected voltages.
