Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cigarette sidestream smoke purification device for purifying sidestream smoke generated from a cigarette smoked by a pipe.

[0002]

[Prior art]

 As a purification means used for smoking, there is a pipe with a filter or a device for collecting and purifying smoke emitted into the air by an air purifier. However, most of the smoking is carried out in a smoking place where no air purifier is installed, so it is mostly annoying to the surroundings.

[0003]

[Problems to be solved by the invention]

 When smoking, the smoker often smokes using a pipe with a filter, etc., and the harm of smoking can be reduced. In addition, the smoke once inhaled by a person is relatively less harmful to others than the sidestream smoke. On the other hand, sidestream smoke is generated from cigarettes when people do not inhale the smoke, and this sidestream smoke has a strong odor and damages the surroundings. Although it is conceivable to use a device such as an air purifier to suction and purify the sidestream smoke, once it is released into the air, it contaminates the air, and even if it is cleaned after it is released, the surrounding air can be truly purified. I can't say that.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a sidestream smoke purification device for cigarettes in which sidestream smoke is purified by a simple means and the environment is improved. And

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is a purifying device for purifying a sidestream smoke generated when a cigarette is shaken when smoking by using a pipe, and a smoking passage and a sub-passage provided in the pipe. From the smoke passage, the suction port communicating with the smoking passage and formed on the pipe side, and the sidestream smoke purifying unit connected to the pipe through the flexible tube and communicating with the sidestream smoke passage. The sidestream smoke purification unit constitutes a sidestream smoke purification device for cigarettes that sucks and purifies the sidestream smoke from the pipe side and discharges the purified smoke to the pipe side and / or the atmosphere side. It is a thing. More specifically, a partition wall is provided in the pipe, and a smoking opening and a sidestream smoke opening communicating with the smoking passage and the sidestream smoke passage are formed in the partition wall. Is characterized by a sidestream smoke purifying device for cigarettes, which is provided with an on-off valve for selectively opening and closing the both openings. Further, the sidestream smoke purification section communicates with the suction / exhaust means for sucking and / or discharging the sidestream smoke, the sidestream smoke cleaning filter, and the sidestream smoke passage and / or the atmosphere side for purification. An exhausting part for exhausting the exhausted sidestream smoke is provided, and the intake / exhaust means is composed of an intake fan or intake and exhaust fans. Further, the sidestream smoke purification section is of a desktop type or a portable type, and an ashtray, a cigarette butter, and a small case are selectively attached to the sidestream smoke purification section. .

[0006] Normal smoking is performed through the suction port of a pipe, but when the smoker stops the suction, sidestream smoke is generally released into the atmosphere. In the case of the present invention, the sidestream smoke is sucked from the sidestream smoke passage in the pipe toward the sidestream smoke purification section. The sidestream smoke that has been sucked and purified by a filter or the like is discharged from the sidestream smoke purification section directly to the atmosphere side or once returned to the pipe side and discharged. Therefore, the damage caused by sidestream smoke can be greatly reduced compared to the conventional case. Further, by providing a partition wall in the pipe and selectively opening and closing the smoking opening and the sidestream smoke opening, the sidestream smoke can be treated more reliably.
