Many people find it impossible to smoke indoors and have to smoke outdoors or on the veranda for reasons such as dirty walls or poor health other than the smoker. With the excitement of the anti-smoking campaign, even in coffee shops and restaurants where people were able to smoke with a big face, smoking seats have recently been set up in the interior of the room, and smokers can go around in the smoking seats. More people have to refrain from smoking.

[0003] Like drinking, alcoholic drinking, which is a nuisance, does not become a nuisance unless it is rampaged or entangled with others. Hated. Tobacco smokers are not bothered by the smoke of their own tobacco, but the smoke of others is disgusting. As much as tobacco smoke is hated. However, even for hated tobacco smoke, secure a space inside the room, define the space as a smoking area, partition the area so that the smoke of the tobacco does not leak outside, forcibly purify the air inside or use it outdoors. There is no problem if it is discharged to Separating smokers from non-smokers by confining smoke in a certain space in this way is generally referred to as smoking separation.

[0004]

However, in a small coffee shop or restaurant where there is no space for partitioning the room into two spaces, the smoking and non-smoking seats cannot be shielded. In such a case, it is necessary to install a powerful ventilation device for discharging smoke or an air purification device for purifying smoke so that the room is not filled with smoke, but this has not been easily realized. for that reason,
As always, smokers smoked while smoking in the smoking area, and non-smokers often smoked in the non-smoking area.

The present invention has been proposed in view of the above-mentioned problems, and is inexpensive and simple in that the smoke of the surrounding cigarettes is quickly sucked and the smoke is not scattered without requiring a large-scale device. It is an object of the present invention to provide a smoke collecting and filtering device having a structure.
