Abstract

The invention relates to an electronic cigarette control circuit. The electronic cigarette control circuit comprises a heating element, a power supply device and a first switch circuit; the power supply device is connected with the heating element and used for supplying power to the heating element, and the first switch circuit is connected between the power supply device and the heating element to form a power supply loop. The electronic cigarette control circuit further comprises a second switch circuit, a resistance value detection circuit connected with the second switch circuit and a control unit; the second switch circuit and the resistance value detection circuit are connected between the power supply device and the heating element to form a detection loop independent of the power supply hoop, the resistance value detection circuit is used for detecting a resistance value of the heating element, and the control unit is connected with both the first switch circuit and the second switch circuit and used for controlling the first switch circuit and the second switch circuit to achieve the effect that one of the first switch circuit and the second switch switch is switched on and the other is switched off. The electronic cigarette control circuit has the advantage of being low in energy consumption. The invention further relates to an electronic cigarette control method and an electronic cigarette.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to an electronic cigarette control circuit and a control method, and also to an electronic cigarette. Background technique [0002] An electronic cigarette is an electronic device that supplies power to a heating wire through a battery, and the heating wire generates heat to atomize the e-liquid, thereby achieving the smoking effect. During the use of electronic cigarettes, it is often necessary to measure the resistance of the heating wire. If traditional electronic cigarettes want to measure the resistance of the heating wire, a current-sensing resistor needs to be connected in series in the power supply circuit. The resistance of the heating wire is calculated by measuring the voltage value at both ends of the heating wire and the current value of the current-sensing resistor. Since the current-sensing resistor is always connected in series in the power supply cir...
