Cigarette filter element

Abstract

The invention relates to the field of cigarette filter elements, in particular to a cigarette filter element. The element comprises a filter tip shell; a smoke inlet is formed in the upper end of thefilter tip shell; a smoking port is formed in the lower end of the filter shell; a connecting rod is arranged above the filter tip; a first rotating bearing is fixed in the middle of the connecting rod; a rotating shaft is mounted in the middle of the first rotating bearing; at least two fan blades are mounted at the upper part of the rotating shaft; a square block is fixed at the lower end of therotating shaft; the lower end of the square block is in contact connection with a pressing groove formed in the upper end of a hollow circular-truncated-cone supporting plate through melt-blown cloth. At least two first vent holes are formed in the hollow circular truncated cone support plate; harmful substances such as tar in the melt-blown cloth are centrifugally separated from the melt-blown cloth through the first rotating bearing, the rotating shaft, the fan blades, the hollow circular truncated cone support plate and the melt-blown cloth outer edge fixing device, so that the harmful substances are sputtered into the filter tip shell, the melt-blown cloth always keeps good filtering capability, and meanwhile, the smoking smoothness of a smoker is kept.

Description

technical field [0001] The invention relates to the field of cigarette filter element, in particular to a cigarette filter element. Background technique [0002] Current cigarette filter devices generally use metal cooling methods to condense tar on the metal core. Some cigarette filter devices use acetate fibers to filter particulate matter in the smoke through physical collision capture, reducing the impact of smoke on smokers. hazards. [0003] After retrieval, Chinese Patent No. is CN203801727U patent, discloses a kind of cigarette filter tip, comprises cigarette filter tip housing; Wherein, described cigarette filter tip housing comprises smoking area, filter area and cigarette area; The end of the area to the beginning of the cigarette area III is successively provided with a non-photocatalyst filter layer and a polypropylene electret filter layer, and the cigarette filter of the present utility model is provided with a polypropylene electret filter layer in the cigar...

[0003] After retrieval, Chinese Patent No. is CN203801727U patent, discloses a kind of cigarette filter tip, comprises cigarette filter tip housing; Wherein, described cigarette filter tip housing comprises smoking area, filter area and cigarette area; The end of the area to the beginning of the cigarette area III is successively provided with a non-photocatalyst filter layer and a polypropylene electret filter layer, and the cigarette filter of the present utility model is provided with a polypropylene electret filter layer in the cigarette filter, reducing more than 90%. smoke particulate pollutants, and then set a non-photocatalyst filter layer in the cigarette filter, effectively reducing nicotine, nitrosamines, benzopyrene and other harmful substances in the smoke, and reducing the harm to the body during smoking. At the same time, smoking The smoker cannot see the smoke when exhaling, which can effectively improve the pollution of the smoke to the environment. However, the device uses a photocatalyst filter layer. When the smoker smokes, the harmful substances intercepted will block the filter layer in the photocatalyst filter layer. Pores affect the smoothness of smoking and affect the filtering effect at the same time
