Description

Functional element for heating cigarettes Technical Field The utility model belongs to the technical field of cigarettes, and relates to a channel element for heating cigarette aerosol and a cigarette. Background Heating tobacco is a tobacco product that heats tobacco to a high temperature of about 300-350 ℃ in a non-combustible manner. The tobacco is not burnt, so that the heated tobacco can release nicotine and other chemical substances, but the aerosol generated when the heated tobacco is used is 90-95% less than the smoke generated after the traditional cigarette is burnt, and meanwhile, the smoke or ash is not generated. Meanwhile, in order to ensure the smoke volume of the product, the adsorption of the filter material to the smoke should be reduced as much as possible, which also leads to the problems of insufficient smoke volume or higher smoke temperature and the like commonly existing in the prior heating non-burning cigarettes, and influences the smoking experience of consumers. Therefore, ensuring the smoke quantity and the smoke temperature control of the heated cigarettes becomes a very important problem, and the structural design development of the aerosol passage element becomes an important technology for the development of the heated cigarettes. Disclosure of Invention The utility model aims to solve the problems in the prior art and provide a cigarette heating element and a cigarette. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: A functional element for heating cigarettes comprises a channel pipe, wherein a plugging piece is arranged in the channel pipe, a peripheral edge part is arranged on the plugging piece, the plugging piece is fixedly connected with the inner wall of the channel pipe through the peripheral edge part, and a through hole extending along the axial direction of the channel pipe is further formed between the plugging piece and the channel pipe. Preferably, two ends of the channel pipe are provided with mutually communicated openings, and two ends of the channel pipe are provided with chamfers. Preferably, the outer surface of the channel tube is provided with a plurality of grooves, wherein the grooves penetrate along the axis of the channel tube. Preferably, the cross section of the groove is semicircular, rectangular, trapezoidal or elliptical. Preferably, the peripheral edge portion extends in a radial direction of the passage tube. Preferably, the blocking piece is arranged at the middle position of the channel pipe. Preferably, the through holes are provided in a plurality, wherein the fluid entering the channel tube can pass through the blocking member through the through holes on the blocking member so as to flow from one end of the channel tube to the other end. Preferably, the cross-sectional shape of the blocking member along the axial direction of the channel tube is spherical, elliptical, spherical crown, spindle or rectangular. Preferably, the ratio of the length and the diameter of the channel tube is greater than 1.1, wherein the diameter of the channel tube is adapted to the diameter of the cigarette, i.e. the outer diameter of the channel tube is not greater than the inner diameter of the cigarette. Preferably, the functional element is processed by polymer materials, including but not limited to polypropylene, polycarbonate, polylactic acid, cellulose acetate. Preferably, the functional element is made of ceramic, glass, metal or other materials. Due to the adoption of the technical scheme, the beneficial effects obtained by the utility model include: 1. According to the functional element disclosed by the utility model, the plugging piece with the through holes is arranged in the channel pipe with the two open ends, so that the functional element has a good plugging effect on a smoke generating material, the smoke generating material is kept from being displaced greatly when the heater is inserted, and the good smoke generating effect is ensured. Meanwhile, the through holes and the channel pipe grooves of the blocking piece enable the cigarettes to form the smoke aerosol to be effectively cooled when flowing through the channel pipe, and due to the fact that the flow cross section is reduced, the flow speed of the smoke aerosol is increased, the temperature of the smoke aerosol is reduced, further cooling of the aerosol is achieved, and the smoking feeling of smoke can be effectively improved; 2. The utility model also discloses a cigarette using the aerosol channel element, and because the aerosol channel element has better cooling effect, smoke formed by burning or heating the cigarette has lower temperature, discomfort caused by higher temperature of the smoke aerosol is greatly reduced, and a cigarette user can obtain better smoking experience during smoking.
