Description

Cigarette Filter {A cigarette filter used by charcoal}

The present invention relates to a cigarette filter, and more particularly, to a cigarette filter for filtering nicotine and tar components harmful to the human body in three steps by dividing the fibrous layer and inserting a filter layer between the fiber layers.

Generally, the cigarette (1) is composed of a cigarette and a cigarette filter, and the smoke sucked out of the cigarette filter contains viscous substances such as nicotine, tar, and more than 4000 toxic substances, which are harmful to the human body. It has been manufactured by forming a fibrous layer or the like to absorb.

The result of this effort is that tobacco filters containing substances such as carbon and activated carbon are attached to the tobacco body as a material for removing nicotine and tar, which raises the manufacturing cost and raises the price of cigarettes, which is causing complaints from smokers. to be.

In recent years, in consideration of the taste and health of smokers, the quality of the cigarette itself is improved, and the structure of the filter is doubled or the carbon particles are interposed to reduce the harmful substances generated during combustion, such as nicotine and tar, to reduce the degree of inhalation by the human body. We focus on developing products that reduce.

As such, a technique devised to improve the function of the conventional tobacco filter is divided into two layers of tobacco filter (Domestic Utility Model Publication No. 98-065409) formed by dividing the fibrous layer and filling silica gel particles in the space. There is a cigarette filter (Domestic Utility Model Application No. 92-10374) in which a chemical filling layer is formed.

As another technique, recently, triacetin, a plasticizer, was mixed with about 2% to 10% of powder containing kitchens containing shellfish and crab shells as a major ingredient, and then dissolved and purified by triacetin. A tobacco filter formed by spraying a solution onto an acetate filter (Domestic Patent Publication No. 2000-2216) is used.

Therefore, the object of the present invention is to dualize the fibrous layer of the cigarette filter into the first and second fiber layers and to insert a filter layer between each of the fibrous layers to filter out toxic substances such as nicotine and tar in three stages, thereby allowing smokers to It is to provide a cigarette filter to eliminate health concerns and maintain health.

Such a structural feature of the present invention is made by inserting char between the fiber layers or inside the fiber layer, or by mixing the char and fiber layers evenly.

Cigarette filter of the present invention for achieving the above object is a filter layer consisting of a fiber layer made of cotton fibers having a myriad of pores, a filter layer for filtering toxic substances, filter paper surrounding the fiber layer and the filter layer, and a tobacco body In the conventional tobacco filter made of a connecting paper for coupling with the tobacco filter;

The filter unit is composed of a first fibrous layer stacked on top of the tobacco leaf, a filtration layer made of charcoal stacked on top of the first fiber layer, and a second fibrous layer stacked on top of the filtration layer. It is done.

Charcoal of the filtration layer includes the evenly distributed in the interior of the first fiber layer and includes the oak charcoal charcoal or bamboo charcoal baked at 1000 ℃ 1300 ℃ or less.

Hereinafter, the present invention will be described in more detail with reference to exemplary embodiments shown in the accompanying drawings.

In the embodiment of the present invention, as shown in Figures 1 to 3, the tobacco filter of the present invention consists of a fiber layer and a filtration layer, the fiber layer is to be wrapped in paper or the like with the filter layer in between.

The charcoal constituting the filtration layer of the present invention is carbon, which is generally composed of carbon and a small amount of minerals, and has been used in daily life by learning the efficacy of charcoal for a long time when science has not developed.

In other words, the charcoal has the effect of increasing the body's immunity, help detoxification, and cleansing, and prevents corruption and preserves freshness, which is used in daily life.

Such charcoal acts as a dehumidifying agent and deodorant, so it is used for deodorization using charcoal's excellent adsorption power, and it acts like a high-performance filter to purify the air by placing it indoors. The focus was on the purification of the smoke.

The charcoal used in the present invention is divided into white charcoal and gum charcoal according to its properties, and most of the charcoal is charcoal (black charcoal). The manufacturing method is to put wood chips in a charcoal kiln and bake at a temperature of 400 ° C. or more and 700 ° C. or less. Lose. At this time, close the kiln entrance and the passage through which smoke escapes with stones or clay and prevent air from entering. Then turn off the lights and let them cool as they are. At this time, the surface of charcoal is black charcoal without ash.

On the contrary, the white charcoal is introduced into the charcoal kiln, which is almost roasted to raise the temperature to about 1000 ° C. or more, and then, at a suitable time, the charcoal is reddish from the kiln entrance with heat. The charcoal and soil are mixed on top of it to cover the burning powder and cool quickly. This action leaves white ash on the surface of the charcoal, called white coal. White coal is naturally fired, long-lasting, and has many fine pores, making it more attractive. All of the finer quality charcoal is as hard as metal and has a metallic sound when beaten.

If the wood is carbonized by pyrolysis, activated carbon is further activated to make more pores, that is, it is subjected to heat treatment again by adding steam of 600 ° C or higher and 900 ° C or lower to the finished charcoal.

The adsorption power varies depending on the number of holes. The more holes there are in the charcoal, the higher the activated carbon has at least 500 m2 / g (about 150 pyeong) of surface area and more than 2000 m2 / g (about 600 pyeong) when the high-performance activated carbon is used. White charcoal is 300㎡ / g (about 90 pyeong).

As shown in Figure 2, the charcoal filled in the filter layer of the tobacco filter according to the present invention is charcoal baked, purified and purified than charcoal or Chinese gum charcoal (black charcoal) baked under 600 ℃ 700 ℃ used as a raw material for roasting, agriculture, industrial It is preferable to fill it with oak charcoal charcoal or bamboo charcoal baked at 1000 ℃ or higher and 1300 ℃ or lower as it is used for deodorization and health.

In other words, the charcoal constituting the filtration layer is pulverized as a solid to absorb harmful components such as nicotine or tar contained in tobacco smoke during smoking.

The charcoal is preferably used in pieces finely chopped oak charcoal charcoal or bamboo charcoal baked at 1000 ℃ or more below 1300 ℃.

In addition, the cigarette filter of the present invention may be mixed with the charcoal evenly distributed in the fiber layer to increase the absorption of toxic substances.

As shown in Figure 2 or 3, the tobacco filter according to the present invention is to filter the toxic substances such as nicotine and tar in three steps by separating the fiber layer up and down, and inserting charcoal between the upper and lower fiber layers. .

Although the present invention has been described with reference to the above embodiments, it is not necessarily limited thereto, and various modifications may be made without departing from the scope and spirit of the present invention.

As described above, the tobacco filter of the present invention maximizes the filtering effect of harmful components such as nicotine or tar by inserting the filter layer between the second fiber layer and the first fiber layer.
