Variable-cavity-volume cigarette holder with tar extruded out in pushing mode

Abstract

The invention discloses a variable-cavity-volume cigarette holder with tar extruded out in a pushing mode. The variable-cavity-volume cigarette holder comprises a suction nozzle, a cigarette insertion tube and a reset spring. A cigarette insertion opening, a smoke inlet channel and a smoke outlet channel are formed in the cigarette insertion tube, a tar collecting cavity is formed between the outer wall of the cigarette insertion tube and the inner wall of the suction nozzle and is communicated with the smoke inlet channel through a smoke inlet hole, and the tar collecting cavity and the smoke outlet channel are communicated through a smoke outlet hole. When the cigarette insertion tube moves towards the suction nozzle, communication between the tar collecting cavity and the smoke outlet hole and communication between the tar collecting cavity and the smoke inlet hole are cut off at the proper time, the tar collecting cavity and the cigarette insertion opening are communicated at the proper time, the volume of the tar collecting cavity is reduced, tar is extruded to the cigarette insertion opening from the tar collecting cavity, after the tar is completely extruded, the reset spring is released through finger pressure, and thus the suction nozzle and the cigarette insertion tube are automatically reset. 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, only one-time pushing action needs to be carried out in the tar clearing away process without part disassembling, additional washing or wiping is not needed due to the fact that the extruded tar is carried away by the cigarette butt, 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 pushing 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 liquid s...

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
