An electronic cigarette is provided. The electronic cigarette includes an electronic cigarette body. The electronic cigarette body includes a suction end, a liquid container for containing cigarette liquid, an atomizing assembly for atomizing the cigarette liquid and a battery rod assembly for supplying power to the atomizing assembly.
