Abstract

The utility model relates to a composite intensified filter tip which belongs to the technical field of tobacco and cigarette filter tip. The lengthened filter tips of present cigarette have the disadvantages of large sucking resistance, poor taste of cigarette and light taste in mouth when using by consumers. The composite intensified filter tip is provided with a metal filter tip between a common cigarette filter tip and a cigarette reel, and the outer surface of the metal filter tip is provided with a spiral air flue. Most of tar in smoke gas is filtered through the principle of metal condensation and centrifugation, and simultaneously the filter ability of the common cigarette filter tip is enhanced. The composite intensified filter tip solves the shortage of background art completely, fabricating cost is lower, and the composite intensified filter tip is completely suitable to the use for the existing cigarette production lines.

Description

Compound potent filter tip

Technical field

The utility model relates to a kind of compound potent filter tip that belongs to tobacco smoke filter tip technical field.

Background technology

At present, cigarette industry knows that all low-coke tar cigarette is the developing direction of World tobacco industry, and tar content is mainly taked following several research direction in the reduction cigarette: 1. start with from agricultural planting; 2. tobacco leaf genetic recombination; 3. utilize porous cigarette paper; 4. adjust cigarette and prop up structure; 5. efficiently hold back filter tip and select additive for filter tip and flue gas dilution technology.The filter tip that wherein extends is a kind of method of having implemented.The common cigarette filter tip mainly is cellulose acetate filter or polypropylene filter tip, and the brachycephaly filter tip can filter 35%～40% of a tar content, and the filter tip natural energy that extends so improves the filtration of tar content.New problem has appearred after yet the lengthening filter tip uses: at first suck resistance during consumer's smoking and increase, and uncomfortable; The filter tip that extends in addition makes the also corresponding reduction of nicotine in the cigarette, thereby causes the consumer that the reduction of comfortable taste degree, the cigarette strength of cigarette are diminished, and is jealous light.So the lengthening filter tip is difficult to promote so far.Therefore, the patentee has applied for " filtering the tar Fireproof cigarette holder by force " patent (patent No. 92237173.3) and has authorized in 1992, it is made up of common cigarette holder and metal filter cylinder, this composite filter tip had both reduced the tar content of sucking cigarette, increased the aeration of cigarette again, be subjected to the great attention of production of cigarettes manufacturer deeply, but found that through further investigation metal filter cylinder processing technology difficulty is big, the cost height, production of cigarettes manufacturer is difficult for accepting.

Summary of the invention

The purpose of this utility model is exactly for solving the compound potent filter tip that disadvantages of background technology provides a kind of high efficiency filter tar, do not influence smoking sensation, low cost of manufacture.

The purpose of this utility model is achieved in that between common cigarette filter tip and cigarette tube and is provided with the metal filter tip, and metal filter tip outer surface is provided with helical intake, is provided with taper hole in metal filter tip both ends of the surface, and taper hole communicates with helical intake.

The utility model is compared background technology and had following advantage: 1. the metal filter tip does not influence resistance to suction and mouthfeel flavor that the consumer sucks cigarette by centrifugal principle and the main filtered tar of condensation principle; 2. the helical intake of metal filter tip makes filter cigarette tar better effects if, has also improved the filter capacity of common cigarette filter tip simultaneously; 3. metal filter tip manufacturing process is simple, and cost is lower, utilizes the metal extrusion process to produce in enormous quantities and be complementary with cigarette production line.

The specific embodiment

The utility model is further described by embodiment below in conjunction with accompanying drawing: as shown in Figure 1 and Figure 2, metal filter tip 3 is located between common cigarette filter tip 1 and the cigarette tube 4, and its outer surface is fixing by sponge paper 2.Both ends of the surface at metal filter tip 3 are provided with taper hole 5, and taper hole 5 communicates with the helical intake of metal filter tip 3 outer surfaces.When the higher flue gas of temperature when the consumer sucks, flue gas is rotation at a high speed after cigarette tube 4 and taper hole 5 enter helical intake, under the acting in conjunction of metal cooling condensation and flue gas centrifugal force, a large amount of tarry matters in smoke are deposited on the inner surface of the sponge paper 2 of clad metal filter tip 3, have greatly improved the filter effect of tar.Flue gas through metal filter tip 3 still is in the high speed rotation status when entering common cigarette filter tip 1, be in the state that laterally rolls when making flue gas by common cigarette filter tip 1, simultaneously again because strong mutually bump of the aerosol particle of rotation and vortex flow motion at a high speed, flue gas particle in the gas phase is condensed grow up, greatly improved the ability that common cigarette filter tip 1 is held back tar.Metal filter tip 3 can be produced in a large number by the metal extrusion process, forms composite filter-tip through automatic rolling up and connecting machine, is adapted at fully using on the existing cigarette production line.

Claims

1, a kind of compound potent filter tip is characterized in that being provided with the metal filter tip between common cigarette filter tip and cigarette tube, and described metal filter tip outer surface is provided with helical intake, is provided with taper hole in metal filter tip both ends of the surface, and taper hole communicates with helical intake.
