Abstract

The utility model discloses a special-purpose cigarette filter tip which relates to filtering devices arranged in cigarettes in tobacco manufacturing industry. A filtering device is additionally arranged at the joint of a cigarette and a common filter tip and uses a triple-chamber cavity (9) as a body, the front and the rear ends of the triiple-chamber cavity (9) are respectively embedded with a multi-hole fire retardant layer (7), a first pressurizing hole (10) and a secondary pressurizing hole (8) are respectively arranged on the wall of the triple-chamber cavity (9), and the periphery is wrapped tightly through an outer wall (4) to form a whole. The outer surfaces of the two multi-hole fire retardant layers (7) are respectively in contact with the cigarette and the common filter tip (6), and an integral filter cigarette is formed after integral connection is carried out through connecting paper (3). Therefore, when peoples smoke, the tar content in each cigarette is reduced below 6 mg, the nicotine content in smoke gas is reduced below 0.7 mg, the carbon monoxide content is reduced below 8 mg, and a great number of harmful substances are controlled from being absorbed into the human body. Shapes, specifications and sizes of the filter tip and the cigarette refer to trade standards.

Description

Cigarette special filtering mouth device

Technical field

The utility model cigarette special filtering mouth device relates to the filter that the tobacco manufacturing is worn in cigarette.

Background technology

The filter tip of being worn in the existing cigarette, what major part adopted is that filter cotton is formed, some high-grade cigarette adds layer of active carbon in the filter cotton cigarette holder, adsorb the harmful substance in the cigarette, but still there is the harmful substance in a large amount of cigarettes to be absorbed, has a strong impact on the healthy of smoker by the smoker.Add active carbon in the filter cotton and make the tobacco curing cost too high, filter effect is unsatisfactory during smoking.

Summary of the invention

The purpose of this utility model provides a kind of cigarette special filtering mouth device, the filter tip front end increases by a filter, it is characterized in that: this device is based on three casees cavitys 9, front and back end at three casees cavitys 9 is inlaid with porous flame-retardant layer 7 respectively, on three casees cavitys, 9 walls, be respectively equipped with once pressurize hole 10 and secondary pressurization hole 8, peripheral packing tightly with outer wall 4 becomes one, and is connected with common filter tip 6, again with whole paper 5 parcels that connect of filter tip.The porous flame-retardant layer 7 on two sides contacts with cigarette and common filter tip 6 end faces respectively, carries out the integral body connection with connecting paper 3.Form three casees filter tip single unit systems of pressurization successively like this.Therefore in smoking process, flue gas is by the priority pressurization of three cavitys, a large amount of harmful substances all are adsorbed on the inwall of each cavity, the tar content of every cigarette is reduced to below the 6mg, nicotine content is reduced to below the 0.7mg, carbon monoxide content is reduced to below the 8mg, has reduced a large amount of harmful substances and has been inhaled in the human body.

The specific embodiment

The utility model cigarette special filtering mouth device is connected the whole paper 5, common filter tip 6, porous flame-retardant layer 7, three casees cavitys 9 of connecting of paper 3, outer wall 4, filter tip by pipe tobacco 1, cigarette paper 2, cigarette and constitutes with filter tip.Most preferred embodiment is: at former regular-size cigarette filter tip front end, increase cover filter of the present invention, this device is based on three casees cavitys 9, front and back end at three casees cavitys 9 is inlaid with porous flame-retardant layer 7 respectively, on three casees cavitys, 9 walls, be respectively equipped with once pressurize hole 10 and secondary pressurization hole 8, the periphery has formed three casees cavity filters that can successively pressurize after packing tightly with outer wall 4 when smoking, this device is connected with common filter tip 6, again with whole paper 5 parcels that connect of filter tip.The end face of two porous flame-retardant layers 7 contacts with cigarette and common filter tip 6 respectively, carries out having formed a complete cigarette with filter tip after whole the connection with connecting paper 3, and the profile of filter tip and cigarette, specification, size are carried out according to industry standard.

Claims

1, a kind of cigarette special filtering mouth device, be in cigarette and common filter tip junction, increase by a filter, it is characterized in that: this device is based on three casees cavitys (9), be inlaid with porous flame-retardant layer (7) respectively in the front and back end of three casees cavitys (9), be respectively equipped with hole of once pressurizeing (10) and secondary pressurization hole (8) on three casees cavitys (9) wall, peripheral packing tightly with outer wall (4) becomes one, and be connected with common filter tip (6), again with whole paper (5) parcel that connects of filter tip.

2, according to the described cigarette special filtering of claim 1 mouth device, it is characterized in that: the porous flame-retardant layer (7) on two sides contacts with cigarette and common filter tip (6) end face respectively, carries out the integral body connection with connecting paper (3).
