Description

  The present invention relates to a portable cigarette smoke cleaner for purifying air containing tobacco smoke when smoking.

  In recent years, in tobacco smoking, non-smokers smoked cigarette smoke regardless of their intentions, and passive smoking and cigarette ash are the same as passive smoking. The inconvenience that hangs around, such as splashing on the desk and soiling the floor, is a problem. As measures to prevent passive smoking, a smoke separation method is adopted that divides the facility into a space that becomes a smoking place in the facility and a space that becomes another non-smoking place. Smoking and non-smoking seats are adjacent to each other, and there are many imperfect ones where the space is not completely partitioned just by installing a screen, and it cannot be said that passive smoking is sufficiently prevented.

  Generally, air purifiers that purify cigarette smoke are used as measures to prevent passive smoking. However, cigarette smoke diffuses into the air. However, it is not possible to suck all the tobacco smoke diffused in the air, and it is not possible to sufficiently prevent the leakage of tobacco smoke flowing from the smoking place to the non-smoking place. Further, the conventional air purifier is effective in purifying air containing tobacco smoke, but does not consider the point that ash is scattered and the desk or floor is soiled.

  In addition, by smoking in the vicinity of the air purifier, it is possible to cause the air purifier to suck before the cigarette smoke diffuses into the air, but it is not always possible to smoke in the vicinity of the air purifier. Even when smoking in the vicinity of the air purifier, the ash of the cigarette being smoked is scattered around by the air discharged from the air purifier, and the desk or floor is soiled.

  Therefore, by directly sucking and purifying the air containing smoke rising from the tip of cigarettes and smoke exhaled by smokers, the cigarette smoke is prevented from spreading to the surroundings and the ash of cigarettes is scattered around There is provided a portable air purifier that prevents this from occurring (for example, see Patent Document 1).

  This portable air purifier has a housing formed therein with a passage through which air containing cigarette smoke passes, and a suction opening with one end open and the other end connected to the passage of the housing. A filter that is provided on the flow path downstream of the suction member and purifies air containing smoke sucked from the suction member; and a filter on the flow path of the casing. A motor with a fan provided downstream, an exhaust port for discharging the air purified by the filter, and an ashtray whose upper part is connected to the suction member. A suction part that sucks in air containing smoke, and a tobacco placement part that communicates with the suction part through a hole and places the cigarette when it is not held in the mouth.

According to this portable air purifier, the process of passing through the flow path, the air containing the smoke is sucked from the suction section to the flow path by blowing the smoke of the cigarette that the smoker exhales at the time of smoking onto the suction section. It is purified by the filter and discharged from the outlet. In addition, air containing smoke rising from the tip of the tobacco when inserted into the tobacco placement portion is sucked from the tobacco placement portion to the suction portion through the hole, and sucked into the flow path from the suction portion, It is purified in the same way as the smoke of cigarettes smoked by a smoker and discharged from the outlet. Furthermore, tobacco ash during smoking is accommodated in the ashtray through a hole provided in the upper portion of the ashtray by inserting the cigarette into the cigarette placement portion and vibrating it.
