Variable cavity volume external draw type extruding tar cigarette holder

Abstract

The invention discloses a variable-cavity-volume cigarette holder with tar extruded out in an outward-sucking mode. The variable-cavity-volume cigarette holder comprises a cigarette insertion tube, a filter element and a suction nozzle. The cigarette insertion tube is provided with a cigarette insertion opening, the filter element is provided with a first step, and a tar collecting cavity is formed among the outer wall of the filter element, the inner wall of the cigarette insertion tube, the bottom wall at the rear portion of the cigarette insertion tube and the first step. A smoke inlet channel and a smoke outlet channel are formed in the filter element, a smoke inlet hole is formed in the inner side of the smoke inlet channel, and a smoke outlet hole is formed in the inner side of the smoke outlet channel. When tar is cleared away, the push-and-pull actions are carried out on the suction nozzle and the cigarette insertion tube so as to change the cavity volume of the tar collecting cavity, communication between the tar collecting cavity and the cigarette insertion tube is directly or indirectly achieved, the tar collected in the tar collecting cavity is extruded out to the cigarette insertion opening in an oriented mode, the tar is attached to a cigarette butt in the cigarette insertion opening, the tar is carried away every time the cigarette butt is thrown away, use is extremely easy and convenient, and use and popularization are easier.

Description

technical field [0001] The invention relates to a smoking set, in particular to a non-removable and washable variable-cavity-volume external-drawing type extruding tar cigarette holder. 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...

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.
