A photosensor 22 senses the temperature of flame when a cigarette lighter 27 is clicked to light a cigarette 15, and its flickering is sensed by a sensing circuit 23 and put out into the control section 24. A motorized blower 2 and a high pressure electric source 5 are set on by the control section 24, and an air purifier is operated for a given period of time. Further, when the gas compound of smoke reaches a gas sensor 17, the same is put into the control section 24 through a sensing circuit 16, and the control section 24 works to turn on the motorized blower 2 and the high pressure electric source 5 prior to a signal from the photosensor 22 and drives the air purifier.
