Cigarette

Abstract

The invention discloses a cigarette, and belongs to the technical field of cigarettes. The cigarette comprises a tobacco shred section; the filter tip comprises a primary filtering section, a deposition section and a re-filtering section which are sequentially connected, the deposition section comprises an inner shell and an outer shell arranged outside the inner shell in a sleeving mode, one end of the inner shell is open and connected with one end of the outer shell through a connecting face, a buffering cavity is formed in the inner shell, and the buffering cavity is communicated with the inner shell. A deposition cavity is formed between the inner shell and the outer shell, a smoke inlet and a smoke outlet are formed in the deposition cavity, and the smoke outlet is formed in the end, away from the connecting face, of the outer shell; the primary filtering section is connected with the tobacco shred section, and smoke generated by combustion of the tobacco shred section sequentially passes through the primary filtering section, the smoke inlet, the smoke outlet and the re-filtering section. According to the cigarette, the primary filtering section, the deposition section and the re-filtering section are matched, so that the smoke can be efficiently filtered while aroma components are reserved, and harmful substances in the smoke can be deposited in the deposition cavity.

Description

technical field [0001] The application relates to a cigarette and belongs to the technical field of cigarettes. Background technique [0002] At present, my country is the country with the largest cigarette sales in the world. As of 2015, my country's smoking population has reached 316 million. Most of the harmful components in cigarette smoke exist in tar. Tar is the product of incomplete combustion of sugars, proteins and other organic substances in shredded tobacco under anoxic conditions. Its composition structure is extremely complex, and it is composed of various hydrocarbons and complex compounds such as hydrocarbon oxides, sulfides and nitrogen compounds. In the process of smoking, the smoke enters the lungs through the respiratory tract, and most of the tar will adhere to the lungs, causing great harm to the lungs and easily inducing lung cancer. [0003] As consumers pay more and more attention to the safety of cigarettes and their own health, reducing the tar an...

Problems solved by technology

At present, the main method of reducing tar and harm of cigarettes is to add adsorbent materials to filter rods of cigarettes to filter smoke. Although it can absorb harmful substances in smoke to a certain extent, the adsorption effect is often not good. , and if the amount of adsorbent material added is too high, it will lead to an increase in the draw resistance of cigarettes, making it difficult to meet people's physiological and psychological needs at the same time, affecting the user's experience
