The method of changing the cavity volume to discharge tar in one direction

Abstract

The invention discloses a method for changing the size of a cavity to discharge tar in one way. The method comprises the steps that when a suction mouth and a cigarette inserting pipe relatively move, the size of the tar collecting cavity between the suction mouth and the cigarette inserting pipe is reduced; along with relative movement of the suction mouth and the cigarette inserting pipe, a smoke channel communicated with the tar collecting cavity is completely or partially cut off, the pressure of the tar collecting cavity is gradually increased, and a one-way tar discharge sealing piece disconnecting the tar collecting cavity from the outside is opened under the action of the pressure of the tar collecting cavity, so that the tar collecting cavity and the outside are directly or indirectly communicated to form a tar outlet channel. Under the action of the pressure, tar in the tar collecting cavity is discharged along the tar outlet channel, the tar is attached to a cigarette butt in a cigarette inserting opening, and the tar is taken away every time the cigarette butt is thrown away. The suction mouth and the cigarette pipe are reset, the size of the tar collecting cavity is gradually increased, communication between the tar collecting cavity and the outside through the one-way tar discharge sealing piece is cut off through the one-way tar discharge sealing piece again, and the smoke channel and the tar collecting cavity are communicated again.

Description

technical field [0001] The invention relates to a method for discharging tar from a cigarette holder, in particular to a method for unidirectionally discharging tar by changing the volume of a cavity. Background technique [0002] As we all know, smoking is harmful to health, because cigarettes contain carcinogens such as nicotine, tar, ammonia, and benzene. Yet smoking has been the habit that people develop in long-term life and work, is not easy to quit, and for this reason, it is the way of last resort to reduce the smoker's inhalation of harmful substances by using a good cigarette holder. [0003] At present, the structure of the cigarette holder on the market is generally to open a number of small holes on the filter tube with the smoke passage, and then set a sleeve with a smooth inner wall outside the filter tube. When the smoke passes through, according to the Coanda effect, the small holes Jet flow principle and condensation principle, the tar in the flue gas is c...

Problems solved by technology

Since the distance between the small smoke inlet hole on the filter tube and the inner wall of the casing cannot be too far, the volume of the oil storage chamber is limited and cannot accommodate much tar. Generally speaking, the tar will fill up the space within the cycle of smoking 10 cigarettes. Part of the space overflows. If it is not cleaned up in time, the smoker will inhale the liquid tar together with the smoke into the mouth, which will have a worse impact on the health and taste of the smoker.

[0004] Therefore, it is particularly important to clean the tar accumulated in the cigarette holder. To smoke a pack of cigarettes, it is necessary to clean the tar in the cigarette holder at least twice or more, and to clean the tar in the cigarette holder needs to carefully disassemble the parts of the cigarette holder, and then wash them with water. Or paper towels to wipe the accumulated tar, and the tar in the small hole of the smoke should be dredged with a fine needle. It is very troublesome to clean the cigarette holder like this, which will bring great inconvenience to smokers, so it cannot be popularized.
