In this way, the cigarette cartridge magazine cover 3 is removed or installed at the same time.

[0035] The battery assembly includes a battery tube 5, a battery tube bottom cover 6, a battery bracket 7, a circuit control board 8 and a battery 9 arranged in the battery bracket 7. The battery tube bottom cover 6 is connected to the bottom of the battery tube 5, the bottom end 14 of the cigarette cartridge compartment 1 is connected to the upper end of the battery bracket 7, the cigarette cartridge compartment 1 and the battery bracket 7 are both arranged in the battery tube 5, and a switching switch 81 is provided on the circuit control board 8. The cigarette cartridge electrodes 22 of each cigarette cartridge are electrically connected to the positive and negative electrodes of the battery 9 through the switching switch 81. By operating the switching switch 81, the power supply lines of each cigarette cartridge can be connected in turn. For example, when the switching switch 81 is operated to connect the power supply line of a certain cigarette cartridge 2, the power supply lines of other cigarette cartridges are disconnected. When the electronic cigarette is in the smoking action, the battery 5 supplies power to the cigarette cartridge, and the cigarette cartridge performs atomization to generate smoke, while other cigarette cartridges do not work.
