Abstract
A device with a separated gas inlet for cigarette set includes a controller switch, a controller switch seat, a transparent light guide seat, a filter holding seat, an insulation fixing sleeve, and a charging base. 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.
