The battery assembly is equipped with a battery and a control circuit for supplying power to the atomizer assembly. The atomizer assembly includes a cigarette cartridge, which is provided with a liquid storage device and a heating unit. When powered on, the heating unit can heat the atomized liquid stored in the liquid storage device and atomize it into vapor mist, aerosol or electronic cigarette smoke for users to inhale.

[0003] The multi-cartridge electronic cigarette contains at least two or more cartridges, each of which can contain atomized liquids of different flavors, and users can choose cartridges of different flavors for use experience. The existing multi-cartridge electronic cigarettes need to switch between cartridges of different flavors, including selecting one of the cartridges by rotating the cigarette holder or the cigarette holder group and placing it in the working position. When the flavor needs to be changed, the cigarette holder or the cigarette holder group is rotated to the working position again, and the air path and circuit of the cartridge are connected to the working air path and circuit through such a mechanical switching method. In the process of switching cartridges, due to the mechanical action of gravity, the air path interface is prone to wear and poor connection, resulting in easy leakage and affecting the amount of smoke sucked out, and it is also easy to cause wear and scratches on the contact parts of the electrodes in the circuit, and the electrode column is easily damaged by swinging, bending or breaking, resulting in poor circuit contact and failure, which seriously affects the user's smoking experience.
