The utility model belongs to the technical field of cigarette filter, in particular, a cigarette filter with automatic ventilation is disclosed, including a filter bar, a forming paper covering the outer circumference of the filter rod, and the loose paper covered on the surface of the forming paper. The characteristic lies in that the forming paper is set with a phase change zone, and the phase change zone is compound with a phase change material layer; The area of the phase change zone covered by loose paper is a ventilation area, and the ventilation area is provided with a number of ventilation holes, and the length of the cigarette filter is 1 to 100mm. A cigarette containing the cigarette filter is also provided. The filter nozzle of the utility model automatically regulates the filter nozzle ventilation with the cigarette smoking schedule, that is, the filter nozzle ventilation rate is zero at the initial suction stage of the cigarette, only the filter nozzle is ventilated at 2~3 ports before the end of the suction, which not only achieves the purpose of reducing the cigarette smoke and reducing the coke, but also reduces the smoke during the last 2~3 sucking process. The gas temperature and smoke concentration can eliminate burning sensation and achieve the consistency and stability of the whole cigarette smoking style.

一种可自动通风的卷烟滤嘴及卷烟
本技术属于卷烟滤嘴设计加工领域,具体涉及一种卷烟滤嘴材料。
技术介绍
卷烟滤嘴已成为卷烟降焦减害的重要介质,行业内外在卷烟滤嘴材料及结构方面进行了大量卓有成效的研究工作。卷烟滤嘴主要通过气溶胶颗粒经直接截留、惯性碰撞和扩散沉积而实现对烟气中有害成分的截留过滤,这不仅与滤嘴的物理性质及结构密切相关,而且与卷烟滤嘴温度分布密切相关。在卷烟最后2~3口抽吸过程中,烟气浓度和烟气温度升高,其中烟气中总料相物及有害物质的浓度明显高于前面1~4口,并且滤嘴烟气温度最高可达70℃~80℃,在深度抽吸模式下滤嘴端的烟气温度甚至达到了100℃以上,过高的烟气温度和浓度不仅影响滤嘴对烟气中有害成分的截留效果,还会产生灼烧感,影响整支卷烟抽吸风格的一致性和稳定性,降低消费者对烟气感官质量的满意度。由此可见,卷烟滤嘴中烟气温度对滤嘴截留效率和感官质量能够起到关键作用。利用滤嘴通风稀释减害降焦,已经在卷烟产品中得到广泛应用。滤嘴通风在稀释烟气的同时,可以利用环境常温空气与烟气在滤嘴内的热交换,降低滤嘴温度。然而,在卷烟抽吸过程中烟气组分是呈逐口递增的趋势,在最初抽吸阶段,滤嘴通风稀释会导致烟气香味成分过低而影响口感。现有技术中,为降低卷烟的温度、有害成分,大多为在卷烟滤棒中添加各类功能添加剂。以降低卷烟最后三口的温度为例,现有技术报道的方法主要是在卷烟滤棒中添加相变材料;例如,公开号为CN105996121A的中国专利文献公开了一种可通过相变释放功能物质的滤棒添加剂。公开号为CN104263321A的中国专利文献公开了一种可调控卷烟滤嘴烟气温度的复合 ...
