The method of changing the volume of cavity to discharge tar

Abstract

The invention discloses a method for discharging tar by changing the size of a cavity. The method comprises the following steps that when a suction nozzle and a cigarette insertion pipe move relatively, the size of a tar collection cavity between the suction nozzle and the cigarette insertion pipe is decreased; along with relative movement of the suction nozzle and the cigarette insertion pipe, a smoke channel communicated with the tar collection cavity is totally or partially cut off, a gap gradually appearing between the suction nozzle and the cigarette insertion pipe forms a tar outlet channel communicating the tar collection cavity and a cigarette insertion opening, and tar inside the tar collection cavity is discharged into the cigarette insertion opening through the tar outlet channel along with reduction of the size of the tar collection cavity; the suction nozzle and the cigarette insertion pipe are reset, the oil outlet channel is cut off, and the smoke channel and the tar collection cavity are communicated again when the size of the tar collection cavity is gradually increased. The tar collection cavity and the cigarette insertion opening are communicated directly after a smoke outlet and / or a smoke inlet communicated with the tar collection cavity is properly closed during the push-pull or pull-push motion, tar collected inside the tar collection cavity is extruded to the cigarette insertion opening directionally, tar is attached to a cigarette end inside the cigarette insertion opening, and tar is brought away every time the cigarette end is lost.

Description

technical field [0001] The invention relates to a method for discharging tar from a cigarette holder, in particular to a method for changing the volume of a cavity to discharge tar. 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 converted into a liq...

AI Technical Summary

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.
