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

Embodiment 1

[0063] refer to Figure 1-2 , present embodiment discloses a kind of cigarette, and this cigarette comprises: shredded tobacco section 30; Filter tip, and filter tip comprises the initial filtering section 20, sedimentation section 10 and refilter section 21 that are connected successively, and sedimentation section 10 includes inner casing 12 and sheathing The outer casing 11 outside the inner casing 12, one end of the inner casing 12 is open and connected to one end of the outer casing 11 through a connection surface 15, a buffer cavity 14 is formed inside the inner casing 12, the inner casing 12 and the outer casing 11 A deposition chamber 13 is formed between them, and the deposition chamber 13 is provided with a smoke inlet 16 and a smoke outlet 17, and the smoke outlet 17 is arranged on the end of the outer shell 11 away from the connection surface 15; the primary filter section 20 is connected with the shredded tobacco section 30, and the shredded tobacco section 30 The...

Embodiment 2

[0084] refer to Figure 4-5 The difference between this embodiment and Embodiment 1 is that the end of the inner casing 12 away from the connecting surface 15 is a closed end, and the smoke inlet 16 is arranged at the connection between the connecting surface 15 and the inner casing 12, which can make part of the smoke The gas circulates in the buffer chamber 14 and then enters the deposition chamber 13 through the smoke inlet 16. The flue gas first moves upwards into the buffer chamber 14, and then moves down through the lower smoke inlet 16 into the deposition chamber 13, so that the flue gas The residence time in the buffer chamber 14 can be extended, and then the flue gas can achieve the first collision in the buffer chamber 14, so that the harmful substances in the flue gas can be preliminarily deposited, and the effect of reducing coke and harm can be increased; in addition, the setting of the buffer chamber 14 can extend the The path of flue gas flow reduces the tempera...

Embodiment 3

[0095] refer to Figure 6-7 , the present embodiment is based on the embodiment 1 to increase the interception cap, the interior of the interception cap forms an interception cavity, and the interception cavity communicates with the smoke outlet 17, and the interception cavity is provided with a first through hole 44 and a second through hole, and the deposition The flue gas in the cavity 13 enters the interception cavity through the first through hole 44 and flows to the refilter section 21 through the second through hole. With the interception cap set, the flue gas flowing out from the smoke outlet 17 enters the interception chamber again, which changes the flow path of the flue gas again, prolongs the flow distance of the flue gas, and makes the harmful substances be eliminated again during the flow of the flue gas. Effectively trapped in the trapped cavity, the harmful components in the smoke entering the oral cavity are further reduced, and the harmfulness of cigarettes i...

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...
