Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier for smoking, which is installed in a smoking room, a waiting room or the like to purify cigarette smoke.

[0002]

2. Description of the Related Art Conventionally, an air cleaner of this type has been disclosed in Japanese Patent Laid-Open No.
The thing described in 0-42325 is known.

The air cleaner will be described below with reference to FIG.

As shown in the figure, a filter housing chamber 1 for housing a filter 101 for purifying cigarette smoke and the like.
Blower 103 sucking air through 02 and filter 101
And a partition plate 1 in the vertical direction in the fan storage chamber 104 for storing the
An ashtray 107 is detachably provided at the center of the upper part of the box-shaped main body 106, which is divided into two parts by 05, and the periphery of the ashtray 107 is formed by punching metal or the like in the shape of an inverted bowl around which the filter storage chamber 102 The exhaust port 109 communicating with the filter 101 is provided, and the suction surface 110 of the filter 101 is arranged in the vertical direction.

In the above structure, while the air purifier is in operation, a smoker smokes a cigarette in the vicinity of the main body 106 and the ashtray 1
When using 07, the smoke generated from cigarettes and smokers' mouths is sucked through the suction port 108 to the filter storage chamber 102.
After being sucked in by the filter 101 and the smoke is purified by the filter 101, the purified air is exhausted from the exhaust port 109.

[0006]

Since such a conventional air purifier is an air purifier to be placed in a narrow place such as a smoking room or a waiting room, a compact structure is required, and therefore pressure loss is reduced. The large filter 101 must be placed vertically in order to increase the area, and when it is placed vertically, there is a problem in that the filter 101 may fall over when the filter 101 is replaced, or the replaced filter may easily come off the filter frame and maintainability is poor. Therefore, even when the filter 101 is installed vertically, it is required to improve the maintainability by providing a structure in which the filter 101 can easily fall over or be removed from the filter frame during replacement.

[0007] Further, the cigarette is stuck in the ashtray 107 in a needle-like state, and the cigarette and the ash in the ash receiver are visible, so that the appearance is not good, or the ash on the ashtray 107 is sucked into the suction port 108. In rare cases, there is a problem that the life of the filter 101 is shortened by depositing on the surface of the filter 101. Tobacco, which is extinguished and extinguished by fire, is naturally guided to the ash pan, and the entered cigarette is visible from the outside. By making it harder, it is required to improve the appearance and extend the life of the filter.

Further, there is a problem that the air blown out from the exhaust port 109 collides with the floor, and the collision sound generated at this time is reflected on the bottom surface of the main body and goes out to the outside to increase the noise. It is required to reduce the collision sound generated by the collision.

[0009] Further, when a lit cigarette that should enter the ashtray 107 accidentally contacts the surface around the ashtray, or when the cigarette is extinguished on the surface around the ashtray, the surface of the cigarette is burned by the heat of the cigarette. There is a problem that it tarnishes due to tar content and it makes the appearance unattractive, and a burning cigarette that should enter the ashtray accidentally touches the surface around the ashtray, or the cigarette fire is extinguished on the surface around the ashtray. Even if it does, the surface of the cigarette is not burned by the heat of the cigarette, and even if the tar is discolored, it can be neatly regenerated by wiping.

The present invention solves such a conventional problem. Even when the filter is placed vertically, the filter is not easily fallen down or is not detached from the filter frame when the filter is replaced, and the maintainability is improved. The purpose is to let.

Tobacco which has been extinguished and extinguished the fire is naturally guided to the ash tray to make it look good by making it difficult to see from the outside, and the ash on the ashtray is sucked into the suction port. The purpose is to extend the life of the filter by preventing it from being rarely accumulated on the surface of the filter and clogged.

Another object of the present invention is to provide a smoking air purifier with low noise.

Further, even if a lit cigarette that should enter the ashtray accidentally contacts the surface around the ashtray, or if the cigarette fire is extinguished on the surface around the ashtray, the surface of the cigarette is burned by the heat of the cigarette. Instead, the purpose is to improve cleanability so that it can be neatly regenerated by wiping it off even if it changes color due to the tar content of tobacco.
