Embodiment 1

[0030] refer to figure 1 As shown, the present invention provides a filter tip structure utilizing the change of smoke flow rate to realize high filtration, including the base section and the retention section of the tow structure, the tow structure can be beneficial to the filter rod cutting device in the cigarette production process. Cutting of composite filter rods. The middle part of the retaining section is provided with two spaced cavities respectively forming the first air cavity 11 and the second air cavity 12, and the hollow cavity is conducive to the flow of mainstream smoke. At least two first air chambers 13 are arranged around the first air chamber 11, at least two second air chambers 14 are arranged around the second air chamber 12, and the gap between the first air chamber 11 and the first air chamber 13 is The space between the second air chamber 12 and the second air chamber 14 is connected through the flow hole 15 , and the connection between the first air c...

Embodiment 2

[0032] The main structure of embodiment two is the same as that of embodiment one, as figure 2 As shown, it includes the base section 2 and the intercepting section 1. Two cavities spaced apart in the middle of the intercepting section constitute the first air chamber 11 and the second air chamber 12 respectively, and at least two first air chambers 11 are arranged around the first air chamber 11. The air chamber 13 , the first air chamber 11 and the first air chamber 13 are connected through the retaining hole 16 . A supporting plate 17 is arranged between the second air chamber 12 and the first air chamber 11, and collinear axial openings are arranged on the first air chamber 11, the first air chamber 13, the supporting plate 17, and the second air chamber 12 The flow groove is formed, and the diameters of the air chamber and the air cavity are larger than the width of the flow groove. During the large change of the flue gas flow rate from slow to fast and then to slow aga...

Abstract

The invention provides a filter tip structure capable of achieving high-efficiency filtration through changes of smoke velocity. The filter tip structure comprises a basic segment and an interception segment, wherein two spaced cavities formed in the middle of the interception segment are the first gas cavity and the second gas cavity respectively, at least two first gas chambers are formed around the first gas cavity, at least two gas chambers are formed around the second gas cavity, the first gas cavity is communicated with the first gas chambers through flow passing holes, the second gas cavity is communicated with the second gas chambers through flow passing holes, the first gas chambers and the second gas chambers are communicated through interception holes, smoke sequentially passes through the first gas cavity, the flow passing holes through which the first gas cavity is communicated with the first gas chambers, the first gas chambers, the interception holes, the second gas chambers, the flow passing holes through which the second gas cavity is communicated with the second gas chambers, the second gas cavity and the basic segment, and the diameter of each gas chamber or gas cavity is larger than the hole diameter of each interception hole. When the smoke passes through flow passing cross sections, which are repeatedly enlarged and shrunk, of the interception segment, the velocity and the static pressure of the smoke change so that granular substances in the smoke can rapidly coagulate, and the purpose of reducing the amount of tar is achieved.

Description

technical field [0001] The invention relates to the tobacco industry, in particular to a filter tip structure that realizes high filtration by utilizing the change of smoke flow velocity. Background technique [0002] A cigarette is a tobacco product in which shredded tobacco is rolled into strips with cigarette paper. A cigarette mainly includes cigarettes and filters. All the substances that escape from the end of the filter when the cigarette is smoked are called mainstream smoke, and the rest are called side stream or branch smoke. No matter what kind of smoke contains a lot of harmful substances, the smoke includes gaseous matter and particulate matter (or particulate matter), so in order to enable smokers to minimize the inhalation of harmful substances when smoking, some cigarette factories have begun to filter A composite filter is used in the mouth to absorb and reduce harmful substances. [0003] After the filter rod is connected to the cigarette, it is called a ...
