Cigarette filter unit

Abstract

The invention discloses a cigarette filter unit, comprising a rod body, a suction nozzle and a filter assembly, wherein the filter assembly comprises a cylindrical sleeve, a front filter and a rear filter; a cigarette port is arranged at the head part of the cylindrical sleeve, and the end face of the tail end of the cylindrical sleeve is provided with a smoke discharge port; the front and rear filters are sequentially arranged in the cylindrical sleeve, and the outer side wall of the head end of the cylindrical sleeve is circumferentially distributed with a plurality of positioning bumps. The cigarette filter unit is ingenious and reasonable in structure design, poisonous smoke generated when tobacco is burnt is subjected to layers of filtering, adsorption, deposition and the like by using the front and rear filters in the filter assembly, hazardous substances in the smoke can be completely and efficiently cleared or filtered, the filtering effect is good, and the health of smokers can be better protected.

Description

technical field [0001] The invention relates to the technical field of filtering, in particular to a cigarette filtering device. 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 the long-term life and work, is not easy to quit, and for this reason, how to minimize the harmful substances sucked into the human body is the goal that people have been working hard for. [0003] At present, there are mainly two kinds of cigarette holders on the market, one is a cigarette holder suitable for non-filter cigarettes and cigars, etc., and its main purpose is to avoid direct contact between the mouth and tobacco. The other is a cigarette holder suitable for sucking shredded tobacco, such as a long pipe pot, etc., mainly to lengthen the passage of smoke, so that some tar substances adhere to the surface of the inner cavity o...

AI Technical Summary

Problems solved by technology

The other is a cigarette holder suitable for sucking shredded tobacco, such as a long pipe pot, etc., mainly to lengthen the passage of smoke, so that some tar substances adhere to the surface of the inner cavity of the flue, which is the so-called "pipe oil", but , none of them can comprehensively and efficiently remove or filter out the harmful substances in the flue gas

Therefore, people have adopted methods such as kapok filtration at this problem, although there is certain filtration effect, because it is a layer of filtration mode, adsorption effect is little, still fails to solve better to filter out the tobacco produced in the burning process. The problem of harmful substances, and the filters in the current technology are generally disposable, which increases the cost. People have concerns when using them, which is not conducive to the popularization and promotion of applications.
