Cigarette 1 (Figure 1-a, Figure 1-b and Figure 1-c) is equipped with a tobacco rod 2 (Figure 1-a, Figure 1-b and Figure 1-c). From one of the ends of the tobacco rod 2 (Figure 1-a, Figure 1-b and Figure 1-c), the combined filter formed by the filter sheath 3 (Figure 1-a, Figure 1-b, adjoins it coaxially) Figure 1-c, Figure 2, Figure 3, Figure 4 and Figure 5), the cross-sectional shape of which corresponds to the sectional shape of the wrapper of cigarette 1 (Figure 1-a, Figure 1-b and Figure 1-c ), and as a material hydrophobic paper can be used (for example, paraffin impregnated paper).

In the shell of the filter 3 (Fig. 1a, Fig. 1b, Fig. 1c, Fig. 2, Fig. 3, Fig. 4 and Fig. 5), perforation for performing air ventilation 4 (Fig. 1) a, Figure 1-b and Figure 1-c), (in other terms “air suction”, “air enrichment”), which provides a generally accepted range (usually not less than 30%, but not more than 85%) dilution of the stream of tobacco smoke, sucked into the mouth of the smoker while inhaling cigarette 1 (Fig.1-a, Fig.1-b and Fig.1-c) with a portion of fresh air that does not contain components of tobacco smoke. The combination filter also contains a porous filter element 5 (FIG. 1-a, FIG. 1-b, FIG. 1-in FIG. 2, FIG. 3, FIG. 4 and FIG. 5), which is a bundle and / or a combination

bundles of fibers of a porous material. In addition, the combined filter includes an aqueous tubular 6 (FIG. 1-a, FIG. 1-b, FIG. 1-c, FIG. 2 and FIG. 5) and an ampoule 7 (FIG. 1-a, FIG. 1-b, FIG. 1-c, FIG. 3 and FIG. 5) capsules. The bundle (s) of fibers of the porous filter element 5 (FIG. 1 a, FIG. 1 b, FIG. 1 b, FIG. 2, FIG. 3, FIG. 4 and FIG. 5) form fibers, which may be obtained from mineral, polymer or metal raw materials.

However, it is preferable to use acetate fibers, acetate-cellulose fibers, cellulose fibers, and fibers of thermoplastic, in particular polypropylene. The cost of the combined filter can be achieved by using an inexpensive feedstock, namely filament tow and / or crepe paper.

As the material for the waterproof shell of the filter 3 (FIG. 1-a, FIG. 1-b, FIG. 1-in FIG. 2, FIG. 3, FIG. 4 and FIG. 5), polymeric materials, for example polystyrene, can be used polyethylene clad paper as well as hydrophobic paper, i.e. paper impregnated with a water repellent, such as paraffin. Tubular 6 (Figure 1-a, Figure 1-b, Figure 1-c of Figure 2 and Figure 5) and ampoule 7 (Figure 1-a, Figure 1-b, Figure 1-c, Figure 3 and Figure 5) the capsules are formed by a sealed enclosure (not shown) containing water. As the material of the sealed enclosure, metal, polymer or ceramics can be used. In this case, it is preferable to use aluminum, tantalum, silver, gold or platinum as the metal for the ampoule case; it is preferable to use polypropylene, polystyrene or low-pressure polyethylene from polymers, and ceramics, porcelain or glass ceramics are most suitable for use as ampoule cases from polymers.

The tubular capsule 6 (FIG. 1 a, FIG. 1 b, FIG. 1 b in FIG. 2 and FIG. 5) is placed around the porous filter element 5 (FIG. 1 a, FIG. 1 b, FIG. 1-in FIG. 2, FIG. 3, FIG. 4 and FIG. 5). The housing of the tubular capsule 6 (FIG. 1-a, FIG. 1-b, FIG. 1-c of FIG. 2 and FIG. 5) may be provided with at least one notch that provides positioning of the depressurization zone.

The ampoule capsule 7 (FIG. 1-a, FIG. 1-b, FIG. 1-c, FIG. 3 and FIG. 5) is arranged substantially coaxially with the porous filter element 5 (FIG. 1-a, FIG. 1-b , Fig.1-in Fig.2, Fig.3, Fig.4 and Fig.5) and also contains at least one notch for the above considerations of positioning the depressurization zone.

The shape and geometric parameters of the notch (or notches) can be selected according to well-known rules and laws of resistance of materials so that when an external force is applied to the combined filter in a range of values from 20 to 95 grams, a controlled (exclusively in the notch or notch zone) depressurization of the water-containing housing capsules.

When depressurization of the housing of a tubular or ampoule capsule 6 (Fig.1-a, Fig.1-b, Fig.1-in Fig.2 and Fig.5), 7 (Fig.1-a, Fig.1-b, Fig .1-c, FIG. 3 and FIG. 5) on the surface of the fibers of the porous filter element 5 (FIG. 1-a, FIG. 1-b, FIG. 1-in FIG. 2, FIG. 3, FIG. 4 and 5), the characteristic diameter of which can be from 0.2 to 40 μm, a thin film of water previously contained in the capsule body is formed in the interfiber air space on the surface of the fibers.

From the side of the oral end, a mushroom 8 is built into the filter (Fig. 1-a, Fig. 1-b and Fig. 1-c). Mouthpiece 8 (Figure 1-a, Figure 1-b and Figure 1-c) is made in the form of a housing 9 (Figure 4), for example, of plastic, which interacts with the central holder 10 (Figure 4) by means of damping elements of the mast 11 (Figure 4). On the surface of these elements of the sleeve 8 (Fig.1-a, Fig.1-b and Fig.1-c) are placed in the form of microparticles of the catalyst, mainly highly dispersed platinum (not shown).

Examples of the implementation of the claimed technical solution are presented below.

EXAMPLE 1

In this example, we used 6 standard cigarette blocks with a porous filter and a West branding nut manufactured in accordance with ISO 3402 (cigarette weight 874 ± 20 mg). By weighing, a batch of 30 pieces was selected. cigarettes 1 (Figure 1-a) with a combined

filter so that the differences in their weight does not exceed a value of 1.2 mg.

Of the sorted in this way the number of cigarettes 1 (Figure 1-a) with a combined filter in 10 pcs. separated and weighed an unused filter, 10 pcs. saved as a reference batch, and in each of the remaining 10 pieces. sorted cigarettes 1 (Figure 1-a) carefully remove the nut and in the central part of the porous filter element 5 (Figure 1-a) cigarettes 1 (Figure 1-a) in the fiber bundle of the acetate-cellulose filtering material by mechanical microfilling from the side the oral end of the filter form a recess in which the ampoule capsule 7 (Fig. 1-a) containing 98% vol. deionized water in an aluminum foil casing. The specified capsule is equipped with a V-shaped notch on the outer end surface of the housing directed to the tobacco rod 2 (Figure 1-a). Installed ampoule capsule 7 (Figure 1-a) has a cross section of 24% of the cross-sectional area of the entire combined filter.

Then carefully remove the shells of the modified combined filters 3 (Fig. 1-a) and form a recess on the surface of each porous filter element 5 (Fig. 1-a), the cross section of which reaches 55% of the filter cross-sectional area, and the length is 11% of fiber tow lengths. In the formed recess is placed a tubular capsule 6 (Figure 1-a), the body of which is made of low pressure polyethylene, at 60% vol. filled with distilled water. The housing of the tubular capsule 6 (Figure 1-a) also contains 6 spherical notches, 3 of which are on the inside of the capsule body, and the remaining 3 are on the outside of the housing. Next, the filter shell 3 (Figure 1-a) is rendered hydrophobic by any of the known methods, for example, clad with a waterproof hydrophobic film, and installed in its original place. Then, under the shell of the filter 3 (Fig. 1-a), a mushroom 8 is mounted (Fig. 1-a), having previously deposited and fixed on its central holder approximately 0.05-0.07 mg of catalyst in the form of platinum microparticles.

After that, re-weigh the modified cigarettes 1 (Figure 1-a) and register acquired each of them a new weight indicator.

Then, an automatic smoking machine sets the smoking mode of cigarette 1 (Figure 1-a) with parameters according to ISO 4387 (inhalation volume of 35 ml, inhalation time of 2 seconds, and a pause between breaths of 58 seconds). Then, almost simultaneously, the capsules 6 and 7 (Fig. 1-a) of each modified cigarette 1 (Fig. 1-a) are depressurized by applying a 20-gram force to the hydrophobic shell of the filter 3 (Fig. 1-a) and install them with the muffs 8 ( Figure 1-a) into the working openings of an automatic smoking machine. From the moment of depressurization of the capsules 6 and 7 (Fig. 1-a) and before the installation of the tips in the automatic smoking machine, water from the tubular 6 (Fig. 1-a) and ampoule 7 (Fig. 1-a) capsules destroyed in the notches is in time the form of the film to spread in the interfiber airspace of the porous filter element 5 (Figure 1-a), thereby significantly increasing the filtering properties of the combined filter. After installing the cigarettes 1 (Figure 1-a) in an automatic smoking machine, it is put into operation. Upon completion of the process of heat removal (mechanical "smoking") of the tobacco rod 2 (Figure 1-a) of modified cigarettes 1 (Figure 1-a), the weight of the used filters is weighed. Similarly, they “smoke” on an automatic smoking machine and then use the combined combination filters of the reference batch.

As a result of a quantitative analysis of tobacco smoke filtrate, made by weighing the reference and modified in accordance with the subject of these claims samples of the combined filters used, comparing their weight with allowance for weight adjustments due to the introduced weight of capsules 6 (Fig. 1-a) and 7 (Fig. .1-a), as well as the hydrophobic shell of filter 3 (Fig. 1-a), it was revealed that when "smoking" modified cigarettes 1 (Fig. 1-a) with a combined filter on an automatic smoking machine, an increase in weight inirovannogo filter size without going beyond the range of values from 23 to 31 mg.

In relation to the increase in the weight of the used reference filters, the average value of which was 5.8 mg, this weight gain due to the introduction of tubular 6 and ampoule 7 capsules into the filter (Figure 1-a) was from 3.9 to 5.3 times , which indicates that the combined filter of the proposed design is the same number of times more effective than the prototype.

For the purpose of a qualitative analysis of the filtrate composition, used by “smoking” on an automatic smoking machine) combined filters in accordance with this utility model were placed for 24 hours in 135 ml of ethanol, the extract of which then underwent spectral analysis. The spectral analysis result of the ethanol extract of tobacco smoke filtrate in accordance with this example is summarized below.

As a result of the quantitative analysis of tobacco smoke filtrate, made by weighing the reference and modified in accordance with the subject of these claims samples of the combined filters used, comparing their weight taking into account the weight adjustments due to the introduced weight of the capsules 6 (Fig. 1-b) and 7 (Fig. .1-b), as well as the hydrophobic shell of filter 3 (Fig. 1-b), it was found that when "smoking" modified cigarettes 1 (Fig. 1-b) with a combined filter on an automatic smoking machine, an increase the weight of the combined filter by an amount that does not go beyond the range of values from 21 to 28 mg.

In relation to the increase in the weight of the used reference filters, the average value of which was 5.7 mg, this weight gain due to the introduction of tubular 6 (Fig. 1-b) and ampoule 7 (Fig. 1-b) capsules into the filter amounted to a value of 3 , 7 to 4.9 times, which indicates that the combined filter of the proposed design is the same number of times more effective than the prototype.

For the purpose of a qualitative analysis of the filtrate composition, used by “smoking” on an automatic smoking machine) combined filters in accordance with this utility model were placed for 24 hours in 135 ml of ethanol, the extract of which then underwent spectral analysis. The spectral analysis result of the ethanol extract of tobacco smoke filtrate in accordance with this example is summarized below.

EXAMPLE 3

To obtain the results in this example, 10 standard cigarette blocks with a porous filter and a West flygun manufactured in accordance with ISO 3402 (cigarette weight 874 ± 20 mg) were used. By weighing, a batch of 80 pieces was selected. cigarettes

1 (Fig. 1-c) with a combined filter so that the differences in their weight does not exceed a value of 1.0 mg.

From the number of cigarettes sorted in this way 1 (Fig. 1-c) with a combined filter, 20 pcs. unused filters are separated and weighed, 30 are left as a reference batch, and in each of the remaining 30 pcs. sorted cigarettes 1 (Fig. 1-c) carefully remove the nut and in the central part of the porous filter element 5 (Fig. 1-c) cigarettes 1 (Fig. 1-c) in the fiber bundle of the acetate-cellulose filtering material by mechanical microfilling from the side the oral end of the filter form a recess in which the ampoule capsule 7 (Fig. 1-c) containing 50% vol. deionized water in a polypropylene housing. The specified capsule is equipped with an M-shaped notch on the outer end surface of the housing directed to the tobacco rod 2 (Fig. 1-c). The installed ampoule capsule 7 (FIG. 1-c) has a cross section of 18% of the cross-sectional area of the entire combined filter.

Then carefully remove the shells of the modified combined filters 3 (Fig. 1-c) and form a recess on the surface of each porous filter element 5 (Fig. 1-c), the cross section of which reaches 29% of the filter cross-sectional area, and the length is 50% of fiber tow lengths. In the formed recess is placed a tubular capsule 6 (Fig. 1-c), the body of which is made of porcelain, by 32% vol. filled with deionized water. The housing of the tubular capsule 6 (FIG. 1-c) also contains a notch on the inside of the capsule shell. Next, the filter shell 3 (FIG. 1-c) is rendered hydrophobic by any of the known methods, for example, clad with a waterproof hydrophobic film, and installed in its original place. Then, under the shell of the filter 3 (Fig. 1-c), a mushroom 8 is mounted (Fig. 1-c), having previously deposited and fixed on its central holder approximately 0.05-0.07 mg of a catalyst in the form of platinum microparticles.

After that, the modified cigarettes 1 are weighed again (Fig. 1-c) and a new weight value is acquired for each of them.

Then, an automatic smoking machine sets the smoking mode of cigarette 1 (Fig. 1-c) with parameters according to ISO 4387 (inhalation volume of 35 ml, inhalation time of 2 seconds, and a pause between breaths of 58 seconds). Then, at the same time, capsules 6 and 7 (Fig. 1-c) of each modified cigarette 1 (Fig. 1-c) are depressurized by applying a 95-gram force to the hydrophobic shell of the filter 3 (Fig. 1-c) and install them with muffs 8 ( Figure 1-c) into the working openings of an automatic smoking machine. From the moment of depressurization of the capsules 6 and 7 (Fig. 1-c) and before the installation of the mushings 8 (Fig. 1-c) in the automatic smoking machine, water from the tubular 6 (Fig. 1-c) and ampoule 7 (Fig. .1-c) of the capsules manages to spread in the form of a film in the interfiber airspace of the porous filter element 5 (Fig. 1-c), thereby significantly increasing the filtering properties of the combined filter. After installing the cigarettes 1 (Figure 1-a) in an automatic smoking machine, it is put into operation. Upon completion of the process of heat removal (mechanical "smoking") of the tobacco rod 2 (Fig. 1-c) of modified cigarettes 1 (Fig. 1-c), the filters used are weighed. Similarly, 40 reference cigarettes with a combined filter are “smoked” on an automatic smoking machine and then the combined filters of this reference lot are weighed.

As a result of the quantitative analysis of tobacco smoke filtrate, made by weighing the reference and modified in accordance with the subject of these claims samples of the combined filters used, comparing their weight taking into account the weight corrections due to the added weight of the capsules 6 (Fig. 1-c) and 7 (Fig. .1-c), as well as the hydrophobic shell of filter 3 (Fig. 1-c), it was revealed that when "smoking" modified cigarettes 1 (Fig. 1-c) with a combination filter on an automatic smoking machine, an increase in weight binered filter by an amount that does not go beyond the range of values from 20 to 26 mg.

In relation to the weight increase of the used reference filters, the average value of which was 5.7 mg, this weight gain due to the introduction of tubular 6 (Fig. 1-c) and ampoule into the filter

7 (Fig. 1-c) capsules ranged from 3.5 to 4.6 times, which indicates that the combined filter of the proposed design is the same number of times more effective than the prototype.

For the purpose of a qualitative analysis of the filtrate composition, used by “smoking” on an automatic smoking machine) combined filters in accordance with this utility model were placed for 24 hours in 135 ml of ethanol, the extract of which then underwent spectral analysis. The spectral analysis result of the ethanol extract of tobacco smoke filtrate in accordance with this example is summarized below.

The processed results of the spectral analysis of the ethanol extract of tobacco smoke filtrate obtained in accordance with examples 1-3 made it possible to qualitatively establish that the extract contains a very wide range of the following harmful components of tobacco smoke: carbon monoxide (negatively affects blood hemoglobin), tobacco pyrolysis resins ( cause lung cancer, oral cavity and esophagus in a person), carcinogenic trace elements, tobacco-specific N-nitro compounds, Volatile N-nitro compounds, nicatin (has chron cal taksicheskoe exposure), 3,4-benzopyrene, acetic acid, polyaromatic hydrocarbons, radionuclides, heavy metals (causing a change in the metabolism of liver tissue), halogens, nitrazoaminy (mutogennoe compound), esters, ketones, aldehydes, amines and amides.

Thus, in addition to a very wide range of extractable and bindable in a cigarette filter in accordance with the present application for a useful model of toxic, toxic, mutagenic and carcinogenic components of tobacco smoke, this new technical solution, in comparison with the prototype, is characterized by an increase in its filtration degree, at least at least several times, since the weight of the tobacco smoke filtrate accumulated in our design of a dynamically “wet” filter cigarette is on average more than 4 times the weight tobacco smoke filtrate in the prototype device.

Given in the three examples contained in the description, specific data on the methods and means of implementing the claimed device using the studied materials and known technologies also make it possible to assert that the proposal meets the criterion of the utility model “industrial applicability”.
