Description

505510 A7 B7 V. Description of the invention (This Maoming refers to a breathable filter cigarette according to the introduction of the first paragraph of the scope of the patent application. B This pout cigarette has been disclosed in ep〇875 160 Aw. It has a pout „With a knife, a coaxial ferrule and a mouth shell surround the core of the tadpole coaxially. Tobacco bundles and rafters are selected in grids and sizes to allow smokers to use their mouth covers to ventilate them. When the hole is opened, the smoke will generally lead to the filter housing in the form of a changeover valve, but because of the uncovered ventilation hole, the smoke will mainly pass through the same reducing mouth part n. Therefore, this development-a purpose is for different consumption The behavior of the person quantitatively controls the amount of smoke. If the smoke is aerosol-like when viewed from a physical phenomenon, that is, the mixture of gas and droplets. However, the droplets, which can also be called mists, have significant differences in size, and they are not easy. It is seen by human eyes. Therefore, the inventor proposed whether the sensory evaluation of tobacco smoke, that is, the quality of its flavor '彳 is determined by the size of the droplet of the smoke, and if so, whether this quality can be controlled.' In the first stage, the inventor found Droplet size for Dao does have a positive impact over the quality of tobacco. As a result of these findings, the purpose of the present invention is to make a filter designed to provide smokers with controllable droplet size. The above purpose can be achieved by having patent application scope No. 丨A filter cigarette made according to the features of the item is achieved. A nozzle design manufactured in accordance with the proposal of the present invention has multiple functions. In the first stage, the filter portion facing the tobacco bundle is applicable to China at a very short paper size. National Standard (CNS) A4 Specifications (210 X 297 mm) 4-Printed by the Intellectual Property Bureau Employee Consumer Cooperative of the Ministry of Economic Affairs 505510 A7 _______ B7 V. Description of the invention () 2 Adjust the agglomerate and nicotine value by distance. In the second stage The diameter of the filter is reduced by accelerating the mainstream smoke in this area by a maximum of three times the rate, and the diameter of the filter used by the mainstream smoke to accelerate the smoke in this area is reduced to approximately twice its speed. This filter design will significantly increase its aroma characteristics and have a lower concentration value than a common filter. It has been found that the composition of the size of the smoke and average droplets is subject to flow The effect of the rate change, and the performance of flavor can be increased at higher flow speeds. Because the smoking resistance and maintaining power of the cigarette of the present invention are related to each other, the smoker can achieve a quite pleasant smoking sensation. The present invention will cooperate with the diagram It will be explained as follows: The figure schematically shows a filter cigarette 'it has a tobacco bundle 6 and a filter 7 and is' arranged in the same straight line' and connected via a wrapping paper 8 to a normal 'tobacco bundle' The length is between 55 and 85 mm, and the length of the mouthpiece is between 21 and 27 mm. The wrapping paper 8 is stacked on the interface between the filter 7 and the tobacco bundle about 2-5 mm. Example: One filter with a length of 21 mm A specific example of the mouth: The filter portion 20 on the tobacco bundle side is connected to the tobacco bundle 6 in a form called a single pout, and the mouth side filter portion as a coaxial filter is connected at the end remote from the tobacco bundle 6 4. The single filter forming the tobacco bundle-side filter portion 3 is made of paper (ie, cellulose), and preferably cellulose acetate having a linear fiber degree of 2.50γ denier and a total denier of 35,000. Made and sometimes supplied with activated carbon. The outer diameter of the tobacco bundle-side filter portion 3 is 7.8 mm in one embodiment, and the length is 13.0 ηπη.

505510 V. Description of the invention ($) 42mm water column. Only in the area of the tobacco bundle side filter portion 3, the wrapping paper 8 is supplied to the ventilation holes 5 in the 3 rows, preferably the row of holes surrounds the filter and the nozzle 7, and in the area of the mouth side filter and the nozzle portion 4, The upper wrapping paper 8 is completely air-tight. The side air flow or the ventilation air is sucked into the filter 7 through the ventilation holes 5, which causes the maintenance and ventilation of the agglomerates of the mainstream smoke supplied from the tobacco bundle 6 and the maintenance of the nicotine value. Experts know how to make such ventilation holes, for example, by mechanical or static electricity, or by laser perforation. The mouth side mouthpiece part 4 forming a coaxial filter, the mouth includes a core 1 and a shell surrounding the core 1 coaxially. The core has a diameter of 5.0 mm and a length of 8.0 mm. In one embodiment, it is made of cellulose acetate with a single fiber denier of 5.0 to 8.0y, preferably 6.0y, and a total denier of 15,000 to 25,000, preferably 17,000. The smoke resistance or pressure drop of the core 10 must be 20-40 mmWC, preferably 30 mmWC. The core 1 has a housing 2 coaxially surrounding it, and has an inner diameter of 5.0 mm, an outer diameter of 7.8 mm, and a length of 8.0 mm. It is made of cellulose acetate with a single fiber denier of 1.5 to 2.5y, preferably 2.1y, and total denier of 50,000 to 75,000, preferably 55,000, which results in smoking resistance Or the pressure drop is 80 to 100 mmWC, and preferably 90 mmWC. The overall length of the coaxial filter is 8.0mm, the diameter is 7.8mm, and the pressure drop is 23mmWC, and the range of the pressure drop can be extended from 16 to 29mmWC.
