Description

An extinguished cigarette extinguisher with a box for storing them relates to the tobacco industry, and in particular to extinguishing extinguished cigarettes, as well as their storage and transportation. It can be used to extinguish cigarettes after smoking in residential and non-residential premises, at industrial enterprises in administrative buildings, warehouses, workshops, forest areas.

Known container for tobacco products, consisting of a box, a flat block of matches, incendiary spread (patent RU 2362465 C2, A24F 15/08). The container is equipped with means of storage and ignition of tobacco products.

The disadvantage of this container is the lack of means for extinguishing cigarettes after smoking and, as a result, increasing the likelihood of fires when a smoldering non-extinguished cigarette enters a flammable surface.

A mouthpiece with a device for extinguishing a cigarette is known, comprising a part for placing a cigarette and a tapered portion associated therewith with a through hole along the mouthpiece. The mouthpiece has an insert in the form of a ring filled with fire extinguishing liquid, located in the cigarette placement part (patent RU 2177235 C1, IPC A24B 33/00, publ. 12/27/2001).

The disadvantage of this mouthpiece is the inconvenience of use, as well as the low degree of suppression of the smoldering residue of the cigarette.

The closest in purpose and technical essence is a fire extinguisher, consisting of a housing with an opening of an appropriate length for placing a cigarette butt in it with its fire part inside the hole, the through hole is made with a cross section for tightly gripping the cigarette butt inserted into the hole along its entire side (patent RU 28588 U1, A24F 13/18, publ. 04/10/2003).

The disadvantage of such a quencher is the low degree of quenching of the smoldering residue of a cigarette.

The task of the invention is to increase the degree, efficiency and reliability of extinguishing the unsigned remainder of the cigarette.

The technical result is achieved due to the fact that the cigarette extinguisher with a box for storing them contains a housing with an opening of the appropriate length for placing the smoldering residue of the cigarette with the fire part inside the opening, the cross section of which corresponds to the cross section of the smoldering residue and is made of non-combustible, environmentally friendly material, unlike from the prototype, the quencher case is rigidly fixed to the end of the box, a device is installed at the bottom of the hole to block the access of oxygen to air, which is a part of the hole, the length of which is equal to or greater than the total length of the pyrolysis zones, the porous and solid carbonaceous residue of the unquenched cigarette, at least two grids are fixedly fixed in the lower part of the housing opening, the cells of which are offset from each other. In addition, the device for blocking the access of oxygen can be made in the form of an opening with annular protrusions at its beginning and end, or in the form of an opening representing a truncated cone with a downward taper, an extinguishing agent can be placed in the lower part of the opening of the extinguisher case.

As a result of the search in the patent and scientific and technical literature, technical solutions that have the same set of features and give the same effect were not identified. Therefore, the proposed technical solution meets the criterion of inventive step.

It is known that in the process of decay of a tobacco product, three zones are formed: a pyrolysis zone, a porous zone, and a zone of a hot solid carbonaceous residue. It is known that when tobacco smolders in a tobacco product, heterogeneous reactions of the interaction of carbon with atmospheric oxygen proceed. The basis of the smoldering process of a cigarette is the reaction of atmospheric oxygen with carbon veins of tobacco

$$C+{\mathrm{<figure-callout\; id="2"\; label="O"\; filenames="00000003.png,00000004.png"\; state="\{\{state\}\}">O</figure-callout>}}_2=\mathrm{<figure-callout\; id="2"\; label="C\; O"\; filenames="00000003.png,00000004.png"\; state="\{\{state\}\}">C\; </figure-callout>}{O}_{}{}_2+97659\text{kcal kg mol}\text{, (one)}$$

where CO ₂ is carbon dioxide.

When the concentration of oxygen in the air decreases, the smoldering process of the cigarette stops.

If the pyrolysis zone, the zone of porous and hot solid carbonaceous remainder of the cigarette enters the enclosed space of the device to block the access of quencher oxygen, for example, between the annular protrusions of the opening, the distance between which is greater than or equal to the sum of the lengths of the pyrolysis zones, the porous and solid carbonaceous residue of the unquenched cigarette, or into a truncated cone with a taper directed downward, the access of atmospheric oxygen ceases and the oxidation reaction ceases. This is how to extinguish the smoldering residue of a cigarette.

A device for blocking the access of oxygen is placed at a distance of 2/3 of the smoldering residue of the cigarette from the upper plane of the quencher case, so that the entire unquenched residue of the cigarette is placed in the quencher.

In order to prevent ash particles from falling out of the box when changing the position of the box in the consumer’s pocket, two grids with cells displaced relative to each other are located in the lower part of the quencher case opening. Fallen ash particles through a fixed grid fall into the lower part of the hole and come into contact with the extinguishing agent. Upon contact with them, they are finally extinguished.

As an extinguishing agent in a fire extinguisher the following are used: sodium chloride or potassium chloride or nitrite, graphite, anti-caking additive.

In order to create non-combustible properties, the inner surface of the hole of the extinguisher body is treated with calcium carbonate or flame retardants, i.e. silicic acid salts.

In Fig.1 shows a front view of a quencher extinguished cigarettes with a storage box, figure 2 is a section aa, figure 3 is a section aa.

An extinguished cigarette extinguisher with a storage box contains: (Fig. 1) a housing 1, (Fig. 2) an opening 2, annular projections 3, nets 4, an extinguishing agent 5, (Fig. 3) a truncated cone 6.

Using the extinguisher, the consumer extinguishes the cigarettes as follows.

If you insert an unquenched cigarette with its smoldering fire part into the opening 2 of the housing 1 and press on it, then the pyrolysis zone, the zone of porous and solid carbonaceous residue of the unquenched cigarette fall into a closed volume, between the annular protrusions 3 of the hole. Since the access of atmospheric oxygen is stopped in a confined space, the smoldering residue of the cigarette is quenched. Fallen ash particles through a fixed mesh 4 will fall into the lower part of the hole and come into contact with the extinguishing agent 5, where they are finally extinguished.

Since the holes of the lower mesh are displaced relative to the holes of the upper mesh, when shaking or changing the position in the vertical plane of the quencher, ash particles remain between the cells of the lower and upper grids 4 and do not fall out of the hole of the quencher.

When moving along the conical hole 6, the diameter of the smoldering residue of the cigarette decreases, while the pyrolysis zone, the zone of porous and solid carbonaceous residue is reduced to a minimum size. Oxygen in the pores of the cigarette is squeezed out of it, the concentration of oxygen in the air in the pyrolysis zone decreases, the rate of smoldering due to lower temperatures also decreases. Particles of ash that fall into the lower part of the hole and come into contact with the extinguishing agent finally decay.

To prevent re-ignition, the internal cavity of the quencher hole is covered with a refractory and non-combustible environmentally friendly material.

To increase the consumer properties, comfort and extinguishing culture of unquenched cigarettes, the extinguisher is mounted on one of the end walls of the box for storing cigarettes. This allows you to quickly and economically enough for the consumer to extinguish a cigarette after smoking.
