Cigarette filter tip

Abstract

The invention relates to a cigarette filter tip which comprises a fiber filter section and an outer wrapping paper layer, the bottom of the fiber filter section is connected with a cigarette body, the top of the fiber filter section is sequentially and tightly connected with a melt-blown cloth filter section and a Laval tubular suction nozzle section, and shaping is performed through a shaping layer; the outer wrapping paper layer wraps the shaping layer and is made of negative ion antibacterial paper; an easy-to-tear paper layer is arranged outside the outer wrapping paper layer; the melt-blown cloth filter section and the Laval tubular suction nozzle section are additionally arranged on the basis of retaining part of the fiber filter section of the existing cigarette filter, so that the processes of preliminarily filtering the tobacco tar in the fiber filter section, secondarily filtering the tar and harmful substances in the melt-blown cloth filter section and adhering the tar to the Laval tubular suction nozzle section again can be realized; the whole filter tip is small in resistance and good in filtering effect, and the problem that fibers enter the lung is solved through the melt-blown cloth filtering section; and in addition, due to the design that the outer wrapping paper layer is made of the negative ion antibacterial paper and is combined with the easy-to-tear paper layer, the problem of germ infection in the smoking and cigarette passing process is effectively solved.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a cigarette filter tip. Background technique [0002] It is common knowledge that the smoke produced by burning cigarettes contains hundreds of chemical components that are harmful to the human body, especially more than 40 kinds of carcinogens such as tar and nitrosamines; [0003] In order not to lose the market, tobacco manufacturers have come up with a clever trick to put a filter on cigarettes, saying that it can block harmful chemicals from being inhaled into the body. This move confuses many smokers, who think that they can smoke without any scruples through the filter. As everyone knows, the filtering effect of the filter tip is very limited, and it is nothing more than self-comfort for smokers; [0004] Some people have conducted investigations and studies. The filtration rate of nicotine in cigarettes is 43.28% for long filters and 9.93% for short filters. However, in the smoke...

Problems solved by technology

[0005] Second, since my country introduced cigarette filters for more than 50 years, cellulose acetate has occupied a prominent position; generally speaking, cigarette filters on the market are made of the chemical substance cellulose acetate; however, when people hold When smoking cigarettes, it is easy to break the fiber flaps in the filter tip, and then when smoking cigarettes, the fibers are sucked into the lungs. In the long run, the fibers are deposited in the lungs, which will cause certain damage to the lungs

[0006] In addition, there is a misunderstanding in the traditional packaging method of filter-tip cigarettes. The sponge head of the cigarette directly touched by the fingers makes it a carrier of bacteria and dirt. Almost all people do not realize that they should wash their hands before smoking as before eating , Passing cigarettes during communication becomes a process of cross-infection of various infectious diseases

[0007] In order to solve the above three problems, many domestic research and development institutions and various tobacco companies have carried out research and development to varying degrees. For example, Yuyuantang Pharmaceutical Co., Ltd. has developed and applied for a patent number of 202010879545. The Chinese invention patent for the inhaled cigarette filter. The patent application includes the cigarette body and the filter at one end of the cigarette body. The filter is composed of a filter core and a composite outer wrapping paper layer of the cigarette holder. The filter core is sequentially composed of the first cellulose acetate segment, The third cellulose acetate section, the melt-blown cloth filter section and the second cellulose acetate section are tightly bonded together, and the composite outer wrapping paper layer of the cigarette holder is composed of a slow pressure layer, a shaping layer and an oily paper layer; however, this patent application can only be used in To a certain extent, the filtering effect of tobacco tar is improved, but because the patent application adds a melt-blown cloth filter section on the basis of the existing cigarette filter, the filtering resistance is further increased, that is, the content of harmful component carbon monoxide will increase more, and due to the resistance Adding significantly compromises the smoking experience and therefore only partially solves the first problem above

[0008] Some studies have found that cigarette filters made of plant fibers can also reduce the amount of tar inhaled. For example, the patent number is 201811466231.6, which is a Chinese invention patent named a cigarette / cigar filter rod made of natural materials. The quality formula of the patent application is as follows: 100-150 parts of activated carbon granules; 60-90 parts of plant fiber; 110-140 parts of wheat, 50-80 parts of barley, 30-70 parts of corn, 40-60 parts of buckwheat, 10-40 parts of rice, 5-15 parts of sesame; 5-110 parts of plant adhesive, 5-20 parts of plant preservative, 30-150 parts of plant starter; 10-25 parts of water; the present invention solves the problem that a large amount of smoke is generated when the existing cigarette filter is burned, and it is not easy to degrade , through the cooperation of natural materials and activated carbon, a filter tip rod with good filtering effect and good environmental protection is formed, which can reduce the harm of smoke to the human body; production, and the cost of plant fiber combined with activated carbon is higher than that of the existing acetate fiber. Therefore, it is mostly used for movable filters at present, and is not suitable for disposable filters.

[0009] For the above-mentioned third problem, the current practice is mostly to work hard on the cigarette case, such as the Chinese patent No. 200410006364.7, which is named as a method related to the improvement of filter cigarette packaging. , put the filter cigarettes upside down into the cigarette box, and before the cigarettes are packed into the box, the inner wall of the cigarette box and the filter part of the cigarette can be selectively sterilized, and it can also be irradiated with ultraviolet light during the cigarette boxing process Sterilize and sterilize in order to ensure the sanitation of the filter part of the cigarettes packed into the box. It can also prevent the hand from touching the filter part of the cigarette when extracting the cigarette from the cigarette case, so that the dirt on the hand will not pass through the filter of the cigarette. into the mouth; however, this method of improvement on the cigarette pack not only increases the difficulty of taking the cigarettes, but also cannot really solve the problem of bacterial infection produced by the smoker himself during the smoking process.
