本发明涉及一种吸烟制品，特别一种填充非烟草材料的吸烟制品。The invention relates to a smoking article, in particular to a smoking article filled with non-tobacco material.
背景技术Background technique
普通的吸烟制品，如香烟或卷烟，是一种用卷烟纸围绕烟丝草丝而卷成基本上呈圆杆或棒状香烟。通常，香烟的吸烟端还设有过滤件，比如用醋酸纤维素制成的过滤嘴。当吸烟者在点燃香烟并作出吸气动作时，香烟中的烟草丝燃烧碳化形成一个没有火焰的炽热燃烧区，这个逐渐向后进行的炽热燃烧区产生高温气流对其相近的烟草丝产生干馏作用，并使烟草丝中的挥发性物质产生蒸发并在吸入空气的冷却下形成可见的气溶胶，即白色和浅蓝色烟雾。该烟雾中所含有的尼古丁通过人体呼吸道和肺泡吸收入血,兴奋大脑神经细胞，从而产生尼古丁特有的愉悦感。但是，源自烟草中的多种化学物质在高温条件下的分解反应和复分解反应，会产生大量的焦油及多种有害物质，因此享受低危害尼古丁的愉悦感和降低焦油及有害物质就成为困扰烟草制造商的一个难题。为了大幅度改善公众健康环境，降低烟草的危害和由此产生的法律冲突，相关的技术改进和科学发明均在改进这种状况。R.J雷诺烟草公司的多个专利描述了分段式碳燃料燃烧元件的低焦油香烟，如美国专利US9,220,301、US9,149,072，菲利浦·莫尔斯烟草公司的美国专利US9,185,939也公开了相关技术。A common smoking article, such as a cigarette or cigarette, is a cigarette that is rolled into a substantially round rod or stick with a cigarette paper surrounding the tobacco grass. Usually, the smoking end of the cigarette is also provided with a filter, such as a filter tip made of cellulose acetate. When the smoker lights the cigarette and makes an inhalation action, the shredded tobacco in the cigarette burns and carbonizes to form a fiery burning zone without flames, and this hot burning zone that gradually goes backwards produces a high-temperature airflow that produces dry distillation of the adjacent shredded tobacco , and the volatile substances in the shredded tobacco evaporate and form visible aerosols under the cooling of the inhaled air, that is, white and light blue smoke. The nicotine contained in the smoke is absorbed into the blood through the human respiratory tract and alveoli, and excites the brain nerve cells, thereby producing the unique pleasure of nicotine. However, the decomposition and metathesis reactions of various chemical substances derived from tobacco will produce a large amount of tar and various harmful substances under high temperature conditions, so enjoying the pleasure of low-harm nicotine and reducing tar and harmful substances have become problems A conundrum for tobacco manufacturers. In order to greatly improve the public health environment, reduce the harm of tobacco and the resulting legal conflicts, related technological improvements and scientific inventions are improving this situation. Several patents of R.J Reynolds Tobacco Company describe low-tar cigarettes with segmented carbon fuel combustion elements, such as US Patents US9,220,301, US9,149,072, and US Patent US9,185,939 of Philip Morse Tobacco Company. related technologies.
为了降低抽吸吸烟制品带来的危害，人们还试图对过滤嘴加以改进，例如GB1410048中公开了一种过滤嘴，该过滤嘴的纵向延伸区域设置高渗透性的纸，分隔成至少一个可以给烟雾提供通道的区域和至少有一个填充碳的区域，并将碳作为香烟烟雾中成份的吸收剂。中国专利CN201821901U公开了一种复合微囊香烟过滤嘴，所述过滤嘴棒一端贴装有过滤片，包覆在过滤片外的卷烟纸上开有吸气孔，以实现过滤嘴对烟中有害物质的吸附。In order to reduce the harm caused by smoking smoking products, people also try to improve the filter tip. For example, a filter tip is disclosed in GB1410048. area and at least one area filled with carbon, and the carbon acts as an absorbent for components in cigarette smoke. Chinese patent CN201821901U discloses a composite microcapsule cigarette filter. A filter is attached to one end of the filter rod, and a suction hole is opened on the cigarette paper wrapped outside the filter to realize the adsorption of harmful substances in the cigarette by the filter. .
本发明人也在2003年和2004年申请了以电池电能加热的电子香烟专利，包括中国发明专利ZL03211903.8、ZL03212882.7和 ZL200420031182.0等，这些发明都是旨在给吸烟者提供具有传统香烟优点的低焦油香烟，而尽可能少的不完全燃烧和热解产物。The inventor also applied for patents for electronic cigarettes heated by battery electric energy in 2003 and 2004, including Chinese invention patents ZL03211903.8, ZL03212882.7 and ZL200420031182.0. Cigarettes have the advantages of low-tar cigarettes, and as few incomplete combustion and pyrolysis products as possible.
本发明人在2016年申请了一种微爆微囊香烟,中国发明专利 ZL2016204193031/公告号CN205695718U、PCT/CN2016/096011该香烟与传统香烟外形、点燃方式和吸烟方式都非常相似，不会使吸烟者感受到该新型微爆微囊香烟与传统香烟存在明显不同。而且，该香烟燃烧后的气体成分对气溶胶成分影响很小，吸出的烟雾状气溶胶的化学成分主要取决于微爆微囊中的液体成分且成分比例可以预先设定，因此可以向吸烟者提供一款与传统香烟高度相似的无焦油的微爆微囊香烟。对于该微爆微囊香烟，还需要在内部结构等方面进行优化，为吸烟者提供更好的体验感。The inventor applied for a micro-explosion microcapsule cigarette in 2016, Chinese invention patent ZL2016204193031/announcement number CN205695718U, PCT/CN2016/096011. Participants felt that the novel microburst microcapsule cigarettes were significantly different from traditional cigarettes. Moreover, the gas composition after the cigarette burns has little influence on the aerosol composition, and the chemical composition of the sucked smoke-like aerosol mainly depends on the liquid composition in the micro-explosion microcapsule, and the composition ratio can be preset, so it can be provided to the smoker. Provide a tar-free microburst microcapsule cigarette that is highly similar to traditional cigarettes. For the microburst microcapsule cigarette, it is necessary to optimize the internal structure and other aspects to provide smokers with a better experience.

点燃微爆微囊香烟并吸气时,烟芯4燃烧产生的热气流和辐射热，致使微爆微囊1、2、3、爆开或熔融并在吸入空气的冷却下形成气溶胶烟雾被从吸气通道中微爆微囊的间隙中吸出。When the micro-explosion microcapsule cigarette is ignited and inhaled, the hot air flow and radiant heat generated by the combustion of the cigarette core 4 cause the micro-explosion microcapsules 1, 2, 3 to explode or melt and form aerosol smoke under the cooling of the inhaled air. Aspirate from the gaps of the microburst microcapsules in the aspiration channel.
