Cigarette filter tip

Abstract

The invention relates to a filter tip, in particular to a cigarette filter tip. The cigarette filter tip comprises a filter tip stick. The filter tip stick comprises cylindrical short sticks axially arranged at intervals. The outer surfaces of the short sticks are smooth. Every two adjacent short sticks are connected through a connecting stick. A continuous groove is formed on the annular outer surface of each connecting stick. The filter tip stick is formed by alternately connecting the short sticks and the connecting sticks with the continuous grooves at intervals. An air guide groove is axially formed in each short stick. The air guide grooves in every two adjacent short sticks form an included angle of 180 degrees. The depths of the air guide grooves are not less than those of the grooves of the connecting sticks. According to the filter tip disclosed by the invention, adjacent filter tip sticks are prevented from being meshed in a molding process, the cigarette filter tip can be conveniently molded, smoke can be smoothly circulated, the flowing distance of the smoke is prolonged, and the damage of cigarettes to the health of a smoker is appropriately reduced.

Description

technical field [0001] The invention relates to a filter tip, in particular to a cigarette filter tip. Background technique [0002] As we all know, smoking will bring great harm to the health of smokers. When more and more smoke is inhaled, some parts of the body, such as the lungs and respiratory tract, will have lesions, which will lead to the recurrence of various diseases, serious can cause cancer. Some smokers use pipes to increase the distance of smoke when smoking cigarettes. Most of the high-boiling substances in the smoke condense and settle in the pipes, so the pipes play a role in reducing coke and harm. Although tobacco pipes can reduce coke and reduce harm, in actual use, tobacco pipes are not easy to carry. At the same time, with the long-term use of tobacco pipes, pipes must be cleaned regularly, which brings troubles to smokers. Therefore, most smokers do not Do not smoke with a pipe. The Chinese patent application number is 200780045016.2, and the invent...

Problems solved by technology

[0003] However, in the actual production process of the filter tip, the above-mentioned threaded mouth rod has the following problems: first, in the "tobacco smoke filter and its manufacturing method", it is disclosed that before the mouth rod enters the composite machine, a layer of coating is applied to the outer surface of the mouth rod Composite special paper, after putting the nozzle rods covered with composite special paper into the nozzle rod compounding machine, there will be no toothing between the nozzle rods, and the nozzle rods can be compounded smoothly, but it will consume a lot of time to cover the composite special paper Paper and glue, the process is complicated, and the manufacturing cost of cigarettes is high; second, before the mouth rod is compounded, if the material is not coated on the surface of the mouth rod, it will cause multiple threaded mouth rods to mesh with each other, and the mouth rod cannot be removed from the mouth. The nozzle bar cannot be recombined smoothly; thirdly, after the outer surface of the nozzle bar is covered with paper, the mouth bar is cut in sections, but when cutting the threaded mouth bar, the surface coated paper is easy Collapse, so that the coil paper covers part of the end face of the nozzle rod, resulting in poor ventilation on the end face
