Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cigarette processing apparatus capable of removing harmful substances and malodorous substances caused by smoking.

[0002]

2. Description of the Related Art In recent years, various investigations have revealed that smoking has a bad influence on health, and the smoke itself of cigarettes is harmful and gives off a bad odor, which causes an unpleasant feeling to others. Further, the smoke of cigarettes not only adversely affects the human body, but also causes the yellowing of the inner wall and ceiling of the room and the harmful odor, and smoking is completely disliked by non-smokers. Here, cigarette smoke is a mixture of gas and smoke (a vaporous mixture that is visible in the presence of carbon particulates).
It is a mixture with
It is composed of gaseous substances such as ammonia and hydrocarbons and smoked fine particles. Therefore, in order to remove bad odors and harmful substances from the smoke of cigarettes, an adsorbent having both a function of adsorbing gaseous substances and a function of adsorbing smoke-like fine particles of about 0.1 μm is required.

[0003]

However, activated carbon and iron powder do not have a function of adsorbing both the gaseous substance and fine particles. In addition, generally, according to the observation of the smoking state, the average smoking time is about 3 to 5 minutes per cigarette, and among them, the smoker actually smokes
The number of times is about 10 times, and the time is about 10 to 20 seconds, and the ratio to the whole is only about 5 to 10%. That is, 90 to 95% or more of the smoking time is a state in which smoke is generated from the tip of the cigarette, that is, a state in which sidestream smoke is drifting. Therefore, the removal of this sidestream smoke is important when discussing various types of harm caused by cigarettes. In addition, when a cigarette is rubbed with an ashtray, a foul odor or a harmful substance is generated, especially when fire extinguishing smoke is generated.

Therefore, an object of the present invention is to provide a cigarette processing apparatus which is capable of mainly adsorbing malodorous substances in the sidestream smoke of cigarettes and removing malodorous substances caused by smoking. Another object of the present invention is to provide a cigarette processing apparatus capable of adsorbing malodorous substances and the like caused mainly by fire extinguishing smoke and cigarette butts at the time of smothering cigarettes and removing the malodor and the like caused by smoking.

The one provided. Therefore, the shape of the tubular body does not matter. In addition, it is preferable that the tubular body is made of a material having rigidity and nonflammability capable of maintaining its own shape from the viewpoint of safety. Furthermore, using a material that can visually see the smoke passing inside this tubular body,
This is preferable because the effect of removing sidestream smoke and the like can be easily visually confirmed. To generate sidestream smoke of cigarettes in the butts storage section and direct the sidestream smoke through the tubular body toward the opening side, open a part of the tubular body and It suffices to provide a cigarette placement port that can be located in the cigarette butt storage portion.

The cylindrical body is provided with a suction portion for forcibly sucking the sidestream smoke and the malodorous substance generated in the shell housing portion and exhausting it from the opening portion of the cylindrical body. A vacuum pump, a fan, or other known suction means can be used as the suction means. The suction portion is preferably provided in the vicinity of the opening of the tubular body in order to allow the sidestream smoke and the malodorous substance to effectively pass through the tubular body.

With respect to the effect of removing harmful components of sidestream smoke, the suction amount of the suction portion has a close relationship with the thickness of the filter portion, and increasing the suction amount increases the thickness of the filter portion. There is a need. Further, if the suction amount is further increased, it seems that harmful components are diluted with air and seemed to have the effect of removal, but the harmful components discharged into the room are not so much reduced. For example, when the filter portion is a cylindrical shape having a diameter of 80 to 100 mm, the filter layer has a thickness of 40 to 50 mm, and the suction amount of the suction portion is at least 1.5 liters / minute per cigarette, and preferably Is 3 to 5 liters / minute. Furthermore, when a large number of people use it at the same time, the number of openings is increased, and the suction amount and the thickness of the filter section are increased accordingly.

Modified coal ash is contained in the filter portion. Examples of the modified coal ash include JP-A-59-86687, JP-A-61-90745 and JP-A-61-90745.

[Table 1] True specific gravity: Approx. 2.5 Cation exchange capacity: Approx. 200 meq / 100 mg Bulk specific gravity: Approx. 0.7 Specific surface area: Approx. 70 m ² / g Average particle size: 10 μm The cation exchange capacity and specific surface area are the Scholenberger method and the specific surface area, respectively. It was measured using the BET method.

The modified coal ash to be used may be of one type or a combination of two or more types. In this filter section, sidestream smoke and the like generated in the butts housing section comes into contact with the reformed coal ash. As a result, harmful substances and malodorous substances in the sidestream smoke and the like are adsorbed and captured by the reformed coal ash, and the harmfulness of the sidestream smoke and the like that has passed through the filter portion is reduced and the malodor is removed.

Since the modified coal ash is inexpensive and nonflammable, it is more economical and safe than activated carbon as an adsorbent. The pore size of the modified coal ash is 4
Ammonia can be adsorbed and removed as finely as Angstrom. The particle size of the granular material is not particularly limited, but is preferably about 1 to 5 mm. Further, the modified coal ash granules are a combination of zeolite particles having an average particle size of about 10 μm, and since each particle surface has resinous protrusions with a height of 1 μm or less, Excellent adsorption of smoke-like particles. It should be noted that in the case of a granular material, suction can be performed with a low suction pressure, but in the case of a powdery material, it is necessary to suction with a high suction pressure. In the case of filling in layers, the number of layers is not particularly limited.

It is preferable that the filter portion is provided at a tubular body portion closer to the butts housing portion than the suction portion. This is because the sidestream smoke can directly pass through the filter section. However, it is also possible to provide the butts housing portion, the suction portion, and the filter portion in this order from the bottom, or it is also possible to provide the suction portion in the upper and lower portions of the tubular body and provide the filter portion between these suction portions.

Further, in the tubular body, it is preferable that an appropriate space is provided below the filter portion between the filter and the cigarette butter housing portion to form a smoke trap portion. By forming the smoke trap portion, the modified coal ash in the filter portion can be effectively brought into contact with the sidestream smoke, and the effect of removing harmful substances and the like is enhanced. Further, it is preferable that an appropriate space is provided above the filter portion to form the exhaust gas trap portion. By forming this exhaust gas accumulation portion, similarly, the modified coal ash and the sidestream smoke can be effectively brought into contact with each other, and the effect of removing harmful substances and the like is enhanced.

In a suction type cigarette processing apparatus having a suction section, if the suction section is operated when the cigarette is extinguished in the cigarette butting container or after the extinguishment of the cigarette, a foul odor due to fire extinguishing smoke or cigarette butts is generated. Can be adsorbed and removed in the filter section.

Furthermore, since it is possible to adsorb the odorous substances and harmful substances in the fire extinguishing smoke and the cigarette butt only by filling the butt portion with the modified coal ash, the ashtray is not a source of odors and the like. . In addition, if you fill the cigarette butt with the modified coal ash and press the lit tip of the cigarette against the modified coal ash, it will extinguish instantly and will not generate fire extinguishing smoke at all. As a result, it is possible to prevent the generation of foul odors when extinguishing a fire.

[0022]

According to the invention as set forth in claim 1, since the sidestream smoke generated from the smoking cigarette can be brought into contact with the filter portion, harmful substances in the sidestream smoke and By removing the malodorous substance, the malodor and the like caused by the sidestream smoke can be reduced. According to the second aspect of the present invention, the malodorous substances in the fire extinguishing smoke when extinguishing the cigarette, and the malodorous substances caused by the butts are adsorbed on the modified coal ash. It is possible to reduce a bad smell and the like. According to the invention as set forth in claim 3, harmful substances and malodorous substances are adsorbed from the sidestream smoke generated from smoking cigarettes in the filter portion, and the extinguishing smoke and the malodor caused by cigarette butts can be reduced. .

Even if it is 0, by filling the modified ash 180 into the cigarette butt accommodating portion 160, the malodorous substance of the cigarette butts is also adsorbed, and the malodorous substance in the residual smoke is also adsorbed to leave the residue containing the malodorous substance. It is possible to prevent smoke from directly exiting the ashtray 150.

Further, as shown in FIG. 5 (c), even in the ashtray 200 in which the butts inlet 210 is opened and closed by pushing a button, the inside of the butts container 220 is filled with the modified coal ash 230. By setting, the malodorous substances such as butts and residual smoke are effectively adsorbed to the modified coal ash 230 in the closed butts housing portion 220, and the ashtray 150 of FIG.
Similar to the above example, there is an effect that the bad smell is not directly output to the outside of the ashtray 200.

It should be noted that the present invention is not limited to these examples, but can take various aspects based on the matters described in the claims. Therefore,
Even in a cigarette processing device that has a tubular body and a suction portion and forcibly sucks sidestream smoke of cigarettes generated in the butts storage portion to contact with the reformed coal ash, the reformed coal ash is provided in the butts storage portion. It can also be filled to effectively remove fire smoke and cigarette odor.
