Variable cavity volume internal pressure extrusion tar cigarette holder

Abstract

The invention discloses a variable cavity size internal pressure tar extrusion cigarette holder. The cigarette holder comprises a cigarette insertion tube and a suction nozzle. A smoke inlet channel and a smoke outlet channel are arranged in the suction nozzle. A tar collection cavity is formed between the outer wall of the suction nozzle and the inner wall of the cigarette insertion tube. Smoke inlets are communicated with the smoke inlet channel and the tar collection cavity. The tar collection cavity is provided with extrusion holes. A rear one-way sealing piece is arranged at the outer end of each air inlet. A front one-way sealing piece is arranged between each extrusion hole and a tar accumulation cavity. After the suction nozzle moves towards a cigarette insertion opening, the smoke inlets and smoke outlets are blocked by the cigarette insertion tube, the front one-way sealing piece is pushed away by the pressure in the tar collection cavity, and then a tar discharging channel is formed by the tar collection cavity and the extrusion holes. In the tar clearing process, the suction nozzle and the cigarette insertion tube are pushed and pulled to change the size of the tar collection cavity, tar gathered in the tar collection cavity is extruded to the tar accumulation cavity in a fixed direction according to the working principle of a one-way valve or extruded to the cigarette insertion opening through the tar accumulation cavity from the tar collection cavity, the tar adheres to a butt in the cigarette insertion opening, and the tar is carried away every time the butt is discarded.

Description

technical field [0001] The invention relates to a smoking set, in particular to a non-removable and washable variable cavity volume internal pressure extrusion 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 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, the tar in the cigarette holder must be cleaned at least twice or more. To clean the tar in the cigarette holder, the parts of the cigarette holder need to be carefully disassembled, and then washed with water or Wipe the accumulated tar with a paper towel, and use a fine needle to clear the tar in the small hole of the cigarette. It is very troublesome to clean the cigarette holder like this, which brings great inconvenience to smokers, so it cannot be popularized.
