In the device with the separated gas inlet for cigarette set, air inlet channel for initiating a controller switch is separated from a smoke gas channel for cigarette, thereby avoiding the failure of the controller switch caused by tarry matters of cigarette gas attaching on an initiating hole of the controller switch, and prolonging the service life of cigarette set.
