Abstract
A regulation-type micro-hole groove filter tip is characterized in that an internal layer of enwrapping paper for the filter tip of each cigarette is provided with a dual structure of the micro-hole and the groove at the same time; the micro-hole and the groove are separately arranged into different structure that the micro-hole is arranged to the two ends and the groove is locally arranged or both of the micro-hole and the groove are locally arranged; the groove is arranged into two types of exposed suction end or hidden suction end. The filter tip can adjust the status of the micro-hole or the groove according to the different requirement of the cigarette design index; therefore, the adjustability of the filter tip is formed. The utility model has the features of novel structure, scientific design and feasible implemented technology ; the filter is characterized by the dual structural feature with new gas permeation type and multi adjusting points, which is beneficial for the design and manufacture of the new cigarette and the secondary design of the filter tip aiming at the individuation feature of the cigarette and is beneficial for the smoking quality and the safety requirement of the reducing tar and lessening harm of the cigarette.
Description
Affiliated technical field: the utility model relates to filter stick and the cigarette mainstream flue gas control technique that is used to make cigarette.
Background technology: filter tip is a kind of effective ways of cigarette " reducing tar and reducing harm ", use the control technique of filter tip to cigarette mainstream flue gas quality and safety, be frontier nature technology and the research and development field of current global tobacco circle, filter tip is ventilative to be a kind of effective technology that improves filter tip filter effect and efficient.Breathable technology method commonly used at present is: use methods such as high ventilative filter tip coated papers, groove filter tip coated papers, the outside punching of filter tip yew paper.These methods are compared with common filter tip, have improved the part air permeable effect of filter tip portion prevailingly.But when cigarette burns and sucks, filter tip and cigarette prop up outside permeability, the flue gas mixed effect in the filter tip still is not fine, what perhaps influenced cigarette sucks taste and quality, especially can not be at the smoking property of cigarette style of different qualities, air permeable effect that the realization filter tip is different and the regulation and control of the secondary of filter efficiency make.
Content of the present utility model:
The purpose of this utility model provides a kind of regulation and control making and settlement function that possesses, and the adjustable and controllable type micropore cannelure filter tip of raising filter efficiency and sucking quality, it is characterized in that: groove (8) is initial from an end of internal layer coated papers (2), (6), its length is provided with micropore (9) simultaneously less than internal layer coated papers length H on the internal layer coated papers.
Adjustable and controllable type micropore cannelure filter tip described in the utility model is equipped with local groove on internal layer coated papers and tow filter core section, fluted position has formed the different pressure span of filter core section; Simultaneously, be distributed with N micropore between groove, micropore effectively improves the ventilative mode and the air permeable effect of filter tip; Micropore and the groove binary combination structure on the internal layer coated papers forms the axial and gas passage radially of filter tip, and this makes the filter type of filter tip and efficient produce useful change.
The Modulatory character that adjustable and controllable type micropore cannelure filter tip described in the utility model possesses is specially: to the aperture of micropore, pitch-row, hole count, distribution, arrangement mode etc., or the length of groove, flute profile, groove depth, slot pitch etc. carried out after individual event element or multinomial element adjust, make up, just given the adjustable performance of different ventilated mode of this kind filter tip and different filter efficiency, and a plurality of check point.Especially tool is meaningfully: can be according to kinds of cigarettes sucking quality, the requirement of sucking style and safety index, and carrying out targetedly to filter tip, the secondary regulation and control make.
Technique effect of the present utility model: the first, because filter tip has the diadactic structure of regulatable micropore and groove, when cigarette burnt and sucked, the recruitment and the air permeability of fresh ventilating air can improve 20～50% in the filter tip; Second, because filter tip portion has formed axially and two kinds of pressure spans that gas passage is different with the tow filter core radially, and gas cut mode with different angles when cigarette burns and sucks enters in the axial gas passage and filter core of filter tip, the fresh air of increment fully mixes with main flume, played the effect of dilution and cooling main flume, to form total wetting phase particle of " greatly ".Reduce the dividing potential drop of main flume simultaneously, and low molecule gaseous substance has more ratio and chance to be overflowed by outer surface, make the filter efficiency of filter tip improve 10～0%, the tar in the main flume, nicotine, CO etc. cause harmful substances to be reduced significantly and reduces; Three, because this filter tip that micropore and groove form is ventilative, the change of ventilating mode, fresh air outside was more abundant with mixing of the interior main flume of filter tip when cigarette was burnt and sucked, more even, more effective, this is for the sucking quality that keeps cigarette and to suck style more useful.
Scientific and reasonable, the technical application simple possible of micropore groove filter structures described in the utility model makes filter tip possess the diadactic structure feature of Modulatory character and the new penetrating mode of gas.Help manufacturing and designing of novel filter tip and new product cigarette, be of value to the sucking quality and the security requirement of the personalization of cigarette " reducing tar and reducing harm ".
