[0027] In some embodiments, the battery cell is a pouch cell 14.
[0028] During the battery assembly process, the soft-pack battery cell 14 and the protection plate 13 are fixed inside the cylindrical steel shell 16 by connecting the head shell 2 to the cylindrical steel shell 16.
[0029] The protection board 13 enables the charging and discharging of the soft-pack battery cell 14, while also providing short-circuit protection for the soft-pack battery cell 14.
[0030] The positive electrode tab 6 is connected to the protection plate 13, and the negative electrode of the soft-pack cell 14 is connected to the protection plate 13 through the cylindrical steel shell 16 and the negative electrode nickel sheet 4, so that the positive and negative electrodes of the battery are located at one end of the battery.
[0031] The microphone switch controls the battery to power the e-cigarette. When power is needed, gas is introduced into the air intake channel. The gas reaches the sensor of the microphone switch. After the sensor detects the sound wave of the gas, it connects the P+ port 9 and the protection board 13 to power the e-cigarette.
