Smoke cartridge, power supply assembly, electronic atomizer and active ventilation method

The invention relates to a cartridge, a power supply assembly, an electronic atomizer and an active ventilation method. The smoke cartridge comprises an oil cup and a smoke outlet, wherein an oil bin used for containing atomized liquid is limited by the oil cup; the atomization bin is operably communicated with the oil bin through an oil conveying opening, and an atomization core is installed in the atomization bin and used for atomizing atomized liquid entering the atomization bin through the oil conveying opening; the active inflation assembly has a first state and a second state; in the first state, the active inflation assembly contains air, and the air is isolated from the oil bin; and in the second state, the active air inflation assembly is driven by electric power to compress the air, and the active air inflation assembly is opened by the compressed air so that the compressed air can enter the oil bin. As an active ventilation structure, the active inflation assembly can effectively solve the problem
