Description

一种过滤嘴 技术领域  A filter technology field
本发明涉及一种过滤嘴， 尤其是一种香烟过滤嘴。 背景技术  The present invention relates to a filter, and more particularly to a cigarette filter. Background technique
现有的香烟过滤嘴是衔接在香烟的一端， 即吸入端， 以絮状纤维材料 制成的滤芯被包在裹纸中， 当烟雾通过滤芯被吸入人体内时， 一部分有害 物质被吸附在滤芯内， 在一定程度上减少'了吸烟者对诸如焦油等有害物质 的吸入量。  The existing cigarette filter is connected to one end of the cigarette, that is, the suction end, and the filter element made of the flocculent fiber material is wrapped in the wrapping paper. When the smoke is sucked into the human body through the filter element, a part of the harmful substance is adsorbed in the filter element. , to a certain extent, reduce the amount of inhalation of smokers to harmful substances such as tar.
现有的香烟过滤嘴的结构主要分为两种， 一种是圆柱形的滤芯被包在 裹纸内， 过滤嘴的一端有一与香烟粘合的接口。 这种结构过滤嘴的缺点是 过滤嘴轴向长度受滤芯纤维间的空隙尺寸的限定， 随着滤芯的长度增加， 烟雾通过滤芯时的阻力相应加大， 如超过一定长度则吸烟者会有不适感， 影响香烟的质量； 另一种是滤芯上具有不同截面形的轴向通孔， 如星形、 三角形等贯穿滤芯， 直接通向香烟的吸入端， 这种结构的过滤嘴一般轴向 尺寸较长， 其目的是在不增加气阻的前提下， 用加大过滤嘴的轴向尺寸的 结构来增加滤芯对烟雾的吸附面积， 从而实现过滤效果， 其缺点是过滤嘴 轴向尺寸较长， 而减短过滤嘴的长度显然会削弱了过滤功能。 因此， 现有 的香烟过滤嘴存在着过滤嘴轴向长度与烟气阻力之间， 以及滤嘴轴向长度 与过滤效果之间的双重矛盾。 发明内容 The structure of the existing cigarette filter is mainly divided into two types. One is that the cylindrical filter element is wrapped in the wrapping paper, and one end of the filter has an interface with the cigarette. The disadvantage of this type of filter is that the axial length of the filter is limited by the size of the gap between the filter fibers. As the length of the filter increases, the resistance of the smoke as it passes through the filter element increases accordingly. If the length exceeds a certain length, the smoker may feel uncomfortable. Affecting the quality of cigarettes; the other is an axial through hole with different cross-sections on the filter element, such as a star, a triangle, etc., which penetrates the filter element and directly leads to the suction end of the cigarette. The filter of this structure generally has a long axial dimension. The purpose is to increase the adsorption area of the filter element to the smoke by increasing the axial size of the filter without increasing the air resistance, thereby achieving the filtering effect, and the disadvantage is that the axial length of the filter is long, and the filter is shortened. The length of the display will obviously weaken the filtering function. Therefore, the existing cigarette filter has a double contradiction between the axial length of the filter and the resistance of the flue gas, and the axial length of the filter and the filtering effect. Summary of the invention

所述螺旋通道是滤芯上具有至少一个沿滤芯轴向延伸的螺旋孔。 所述 螺旋通道可以是贯通该滤芯的。 所述螺旋通道也可以是不贯通该滤嘴的。 所述螺旋通道是多条的。  The spiral passage has at least one spiral hole extending axially along the filter element. The spiral passage may be through the filter element. The spiral channel may also be permeable to the filter. The spiral channels are a plurality of pieces.
本发明的一种过滤嘴采用在滤芯中具有至少一个螺旋通道的技术方 案。 该螺旋通道增加了烟雾通过滤芯的路径的长度， 加大了滤芯对一烟雾 的吸附面积， 在离心力的作用下， 烟雾中的有害物质可更多地被吸附在通 道壁上。  A filter of the present invention employs a technical solution having at least one spiral passage in the filter element. The spiral channel increases the length of the path of the smoke through the filter element, and increases the adsorption area of the filter element to a smoke. Under the action of centrifugal force, the harmful substances in the smoke can be more adsorbed on the channel wall.
采用上述结构后， 本发明的一种过滤嘴的滤芯的螺旋通道在气阻不增 加的前提下， 增加了烟雾通过滤芯的路径的长度， 并增大了滤芯对烟雾中 有害物质的吸附面积， 从而达到了改善香烟过滤嘴的过滤效果的目的。 附图说明  After adopting the above structure, the spiral passage of the filter element of the filter of the present invention increases the length of the path of the smoke passing through the filter element and increases the adsorption area of the filter element to the harmful substances in the smoke, without increasing the air resistance. The purpose of improving the filtration effect of the cigarette filter is achieved. DRAWINGS
