Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a smoke cleaning device for removing harmful substances generated from cigarette smoke, and particularly for preventing adverse effects on non smokers around a smoker.

[0002]

2. Description of the Related Art Cigarette smoke and odor that bother non-smokers are not only disliked, but non-smokers also suffer the same harmful effects of smokers as smokers smoke. . For this reason, the smoke-free movement has become popular in recent years, and cigarette lovers have a narrow mind.

Therefore, various cleaning tools have been proposed for covering the ignition part of a cigarette and filtering the smoke generated from the ignition part to purify the smoke. These ideas are based on the idea that the smoke of the cigarette is cleaned during smoking. It is almost satisfied that it prevents the water from flowing out of the equipment into the external environment, and that it does not become hot enough to cause harmful effects such as burns due to ignition.
The most necessary condition of tobacco, which is a luxury item, is lost, and the deodorizing effect is not taken into consideration.

[0004]

SUMMARY OF THE INVENTION The object of the present invention is, of course, to prevent non-smokers from inconvenience and to prevent smoke from leaking into the external environment and prevent burns due to high temperature. It is an object of the present invention to provide a cigarette smoke cleaning device which does not change the taste and has a deodorizing effect which can be surely reduced and pollution can be extremely reduced.

[0005]

The means of the present invention are as follows. A supporting member for holding and smoking a cigarette, and a perforated cylindrical body detachably connected to the supporting member, decomposes and filters harmful substances generated from cigarette smoke,
A cigarette smoke cleaning tool provided with a deodorizing cleaning substance in the perforated cylindrical body.

[Function] Nicotine, tar, etc. are the main harmful components of tobacco. When these components are deodorized only with an adsorbent such as activated carbon, an irritating odor such as an ammonia odor is generated during smoking. The cause of this is not clear, but it is considered to be related to the combustion of trace components contained in tobacco.

Basically, when a cigarette is burnt in the tubular body 2, it is necessary to consider that the adsorbing ability of the adsorbent is almost zero.
The reason is that the adsorption capacity increases as the temperature decreases, while the temperature inside the tubular body 2 during cigarette combustion reaches at least 150 ° C or higher. The adsorbent exhibits a deodorizing effect at room temperature when it does not smoke. Many media, for example, catalysts used for smoke of household cookers, malodors, etc., catalysts for purifying exhaust gas of automobiles, etc. are used at a temperature of at least 200 ° C or higher. This is because the decomposition reaction of malodor in the presence of a catalyst proceeds efficiently at 300 to 600 ° C. Therefore, focusing on the fact that the temperature in the tubular body 2 is at least 150 ° C. or higher,
The use of a catalyst is considered to be suitable for the decomposition of harmful substances during the burning of tobacco.

The catalyst may be any material having the ability to oxidize and decompose harmful substances, and examples thereof include platinum, silica, alumina, calcium aluminate, and metal oxides. A platinum catalyst is particularly suitable at a low temperature of about 200 ° C.

As a material for supporting these catalysts, a heat-resistant material such as silica or glass is preferable because the temperature of the tobacco ignition part becomes 800 ° C. or higher. Further, since it is advantageous for these to have a function of filtering tobacco smoke fine particles that cannot be decomposed, fibrous ones are preferable, and pipe-shaped silica fibers and glass fibers are used.

In order to support a catalyst such as platinum on these supporting materials, for example, a solution of chloroplatinic acid dissolved in water is impregnated into a cylindrical silica fiber, dried and then fired at a temperature of 500 ° C. or higher. Just do it.

According to the present invention, a double-tube body having the above-mentioned tubular body having a function of decomposing / filtering harmful substances of cigarette smoke on the inside and a material for adsorbing and deodorizing the odorous components of tobacco on the outside is used. However, the purpose of adsorption / deodorization is to remove the malodorous components that could not be decomposed / filtered at room temperature. Activated carbon, zeolite, etc. are preferably used as the adsorbent material, and in particular, paper cloth-like activated carbon is suitable for the purpose of the present invention. A paper cloth-like activated carbon is hidden in a tubular shape, and the tubular body for decomposition and filtration is mounted therein to form a double layer.

The heat-resistant perforated tubular body 20 is characterized in that it covers the outside through an air layer between the double tube for decomposing, filtering and deodorizing harmful substances in cigarette smoke. Since the temperature in the double pipe during smoking of cigarettes is at least 150 ° C. or higher and the outer surface temperature of the double pipe reaches about 90 ° C., it is dangerous to grip it with a human hand. The air layer is
The heat-resistant perforated member is provided for the purpose of adiabatic effect of lowering the temperature of the member to a warm degree. The material of the heat-resistant perforated tubular body is metal, plastic, etc.
It can be used if it does not disassemble.

The heat-resistant perforated cylindrical body has a surface area of 30.
% Or more is characterized by having holes for the entry and exit of air. Tobacco is not usually smoked by covering the cigarette, and the oxygen required for incineration is always supplied from air. Since the taste of cigarettes is formed on the assumption that there is sufficient air, if this condition is not satisfied, the taste of cigarettes will change and the taste will be significantly unfavorable. this is,
When the air supply is low, the tobacco burns incompletely,
This is because the original taste cannot be expressed.

Therefore, in order to prevent the taste of the tobacco from being deteriorated, it is necessary to sufficiently supply the air necessary for burning the tobacco. Since the double tube is made of a fibrous material, the tobacco smoke fine particles are filtered and do not leak to the outside, but the air can flow in and out completely, and there is no problem.
Since the heat-resistant perforated tubular body is formed by processing a metal plate or a plastic plate, if the proportion of the holes in the surface area is small, the entry and exit of air is significantly hindered. The larger the ratio of the pores, the more preferable. However, since the mechanical strength for smoking must be maintained, the surface area of the heat-resistant porous cylindrical body is at least 30% or more, preferably 50% or more.
