一种利用电磁感应进行加热的烟具Smoking appliance heated by electromagnetic induction

技术领域technical field

本实用新型属于电加热新型卷烟领域，具体涉及一种利用电磁感应进行加热的烟具。 The utility model belongs to the field of electric heating new cigarettes, in particular to a smoking set which is heated by electromagnetic induction. the

背景技术Background technique

随着公众对卷烟危害性认识的加强和政府对卷烟管制力度的加大，世界各国烟草企业加强了对新型烟草制品的开发。目前，新型烟草制品主要包括新型卷烟、无烟气烟草制品和电子卷烟3大类。其中新型卷烟在生理感受、心理感知、吸食方式等方面最接近传统卷烟，具有很好的发展潜力。 With the strengthening of the public's awareness of the dangers of cigarettes and the strengthening of the government's control over cigarettes, tobacco companies around the world have stepped up the development of new tobacco products. At present, new tobacco products mainly include three categories: new cigarettes, smokeless tobacco products and electronic cigarettes. Among them, new cigarettes are closest to traditional cigarettes in terms of physiological feelings, psychological perception, and smoking methods, and have good development potential. the

已有的研究表明，传统卷烟烟气中的大部分有害成分是烟草在高温燃烧过程中经过热裂解、热合成等反应产生的。因此，如果能降低卷烟产生烟气时的温度，即使用加热而非燃烧烟草的方式产生烟气，可以减少大部分的热烈解与热合成等反应，整体降低烟气中有害成分的释放量。从1985年开始，菲莫、雷诺、英美等大型烟草企业相继开展了加热型新型卷烟的研发工作，形成了三种主要的加热型新型卷烟技术：电加热新型卷烟、燃料加热新型卷烟和化学加热新型卷烟。 Existing studies have shown that most of the harmful components in traditional cigarette smoke are produced by pyrolysis, thermosynthesis and other reactions of tobacco during high-temperature combustion. Therefore, if the temperature at which cigarette smoke is produced can be reduced, that is, the smoke is generated by heating instead of burning tobacco, most of the thermal decomposition and thermal synthesis reactions can be reduced, and the release of harmful components in the smoke can be reduced overall. Since 1985, Philip Morris, Reynolds, Anglo-American and other large tobacco companies have successively carried out the research and development of new heating cigarettes, forming three main new heating cigarette technologies: electric heating new cigarettes, fuel heating new cigarettes and chemical heating New cigarettes. the

电加热新型卷烟方面，菲利普-莫里斯公司(Philip Morris USA)开发的“穿越”(Accord)和菲·莫国际(PMI)研发的“加热吧”(Heatbar)产品是电加热型烟草制品的代表，两者均由特制卷烟和电加热器两部分构成。燃料加热型卷烟方面，使用的热源包括可燃烧固体、液体或气体，其中固体碳质燃料已有商品化产品推出，可燃烧液体或气体则只有专利尚无产品。雷诺公司1988年上市的“卓越”(Premier)和1995年上市的“伊克莱斯”(Eclipse)属于燃料加热型烟草制品，其中后者为前者的改进型。这两种产品所使用的热源均为碳质固体燃料。理化反应加热型烟草制品，其特点在于加热烟草的热量来源于理化反应，但是，该类产品对热量的控制较差，工艺相对复杂，尚未实现商品化。 In terms of new electric heating cigarettes, "Accord" developed by Philip Morris USA and "Heatbar" developed by Philip Morris International (PMI) are representatives of electric heating tobacco products , both of which are composed of special cigarettes and electric heaters. In terms of fuel-heated cigarettes, the heat sources used include combustible solids, liquids or gases. Among them, solid carbonaceous fuels have been commercialized, while combustible liquids or gases only have patents and no products. "Premier" launched by Reynolds in 1988 and "Eclipse" launched in 1995 are fuel-heated tobacco products, and the latter is an improved version of the former. The heat sources used by these two products are carbonaceous solid fuels. Physical and chemical reaction heating tobacco products are characterized in that the heat of heating tobacco comes from physical and chemical reactions. However, this type of product has poor control over heat, and the process is relatively complicated, so it has not yet been commercialized. the

其中，电加热新型卷烟具有加热温度可控、加热方式灵活、使用方便时尚等优点，更容易迎合不同消费者的消费习惯而被消费者接受。 Among them, the electric heating new cigarette has the advantages of controllable heating temperature, flexible heating method, convenient and fashionable use, etc., and is more likely to cater to the consumption habits of different consumers and be accepted by consumers. the

世界范围内，菲·莫公司在电加热新型卷烟领域居于领先地位。菲·莫公司(PM)先后研制出一代、二代电加热卷烟抽吸系统(EHCSS,Electrically Heated Cigarette Smoking System)如Accord、Heatbar等品牌。同时，在电加热吸烟系统方面，菲利普-莫里斯公司公开了多项电加热新型卷烟发明专利(US6615840、US20070074734、US2007102013、US20110155151、US20050172976、US20040129280、US7690385、US20070256697、US20060070633、US20040261802、US20040200488、US7392809、US7293565、US7234470、US7163015、US6810883、US6026820、US6040560、US5988176、US5967148、US5954979、US5934289、US5915387、US5902501、US5878752、US5750964、US5708258、US5692526、US5692525、US5692291、US5666978、US5666976、US5665262、US5591368、US5530225、US5505214、US5499636、US5498855、US5432882、US5388594、US5372148、US5144962、US5060671)，介绍了多种电加热吸烟系统。 Worldwide, Philip Morris is in a leading position in the field of electric heating new cigarettes. Philip Morris (PM) has successively developed first-generation and second-generation Electrically Heated Cigarette Smoking Systems (EHCSS, Electrically Heated Cigarette Smoking System), such as Accord, Heatbar and other brands.同时，在电加热吸烟系统方面，菲利普-莫里斯公司公开了多项电加热新型卷烟发明专利(US6615840、US20070074734、US2007102013、US20110155151、US20050172976、US20040129280、US7690385、US20070256697、US20060070633、US20040261802、US20040200488、US7392809、US7293565 、US7234470、US7163015、US6810883、US6026820、US6040560、US5988176、US5967148、US5954979、US5934289、US5915387、US5902501、US5878752、US5750964、US5708258、US5692526、US5692525、US5692291、US5666978、US5666976、US5665262、US5591368、US5530225、US5505214、US5499636、US5498855 , US5432882, US5388594, US5372148, US5144962, US5060671), have introduced multiple electric heating smoking systems. the

然而，迄今，菲莫推出的两款商品化电加热新型卷烟产品的市场测试均未取得成功，这进一步说明电加热新型卷烟产品目前还处于成长初期，依然存在很多问题，其中尤其体现在电加热器性能低和卷烟感官质量差两个方面。而加热器可以通过其加热效率等影响发烟材料的干馏作用，从而间接影响到新型卷烟的感官质量。因此，电加热器性能是影响电加热新型卷烟制品发展和市场认可的核心因素之一。 However, so far, the market tests of the two commercialized new electric heating cigarette products launched by Philip Morris have not been successful. low organ performance and poor sensory quality of cigarettes. The heater can affect the dry distillation of the smoking material through its heating efficiency, thereby indirectly affecting the sensory quality of the new cigarette. Therefore, the performance of the electric heater is one of the core factors affecting the development and market acceptance of new electric heating cigarette products. the

目前，传统的电阻加热电加热新型卷烟普遍存在以下问题：热能利用率低、响应时间长、控温困难、稳定性和安全性欠佳、使用寿命短。 At present, the traditional resistance heating and electric heating new cigarettes generally have the following problems: low heat utilization rate, long response time, difficult temperature control, poor stability and safety, and short service life. the

仍需要带有新型加热器的烟具。 There is still a need for smoking articles with new heaters. the
