Integrated cigarette filter

Abstract

An integrated cigarette filter that can light up, cut and put out a cigarette, hold ash and butts and filter smoke. It comprises upper and lower casings and is characterized by a smoke-collecting hood arranged on the upper casing and an inlet ventilator furnished inside the hood. The hood is snapped onto the upper casing in a detachable manner. The inlet ventilator is fixed to the upper casing with screws and snap-fasteners. The smoking device is inside the upper casing, while the purification device is inside the lower casing. There is a trimming between the upper and lower casings, and the two casings are connected with snap-fasteners. The device can eliminate passive smoking from the source, and directly purify harmful gases and particles in mainstream and sidestream smoke during use, without causing adverse effects or damage to people around smokers.
