Ignition device and apparatus for filtering and purifying side- stream and second-hand tobacco smoke

摘要

An ignition-filtering system including a multi-stage filtering apparatus with a gravitationally activated ignition device to permit complete isolation of the lighting and smoking process. The ignition- filtering system filters second-hand smoke exhaled by a smoker, side- stream smoke which is evolved from the burning tip of a cigar or cigarette, and initial combustion smoke and gases. The ignition device is battery powered and includes an electrical ignition coil. The multi-stage filtering apparatus includes an enclosure surrounding a smoking product and a base having a filter assembly. A catalytic converter surrounds the smoking product within the enclosure The filters inside the assembly may include a condensation filter, a smoke-absorbing filter, a desiccating filter, a bacteriostatic filter, and a deodorizing filter. Two concentrically disposed smoke conduits provide passage for smoke to be inhaled by the user, and then exhaled back into the enclosure, where the smoke is dried, filtered, and catalytically decontaminated.
