Description

Smoking device for heating non-burning tobacco

Technical Field

The utility model relates to a smoking device for heating non-burning tobacco, belonging to the technical field of cigarette product design and manufacture.

Background

Smokers mainly take nicotine and tobacco natural fragrance in tobacco to achieve satisfaction, traditional tobacco burns at the temperature of over 600 ℃ to generate nicotine and additionally release various harmful substances, and the main components of the harmful substances are tar, carbon monoxide and other substances generated by burning. Although the baking type heating mode cannot completely prevent the generation of tar, the content of the generated tar is very low, and the tar is almost negligible compared with the normal combustion of tobacco. A non-combustible smoking product of philippinary company, which is heated at a temperature of less than 350 ℃ to release nicotine and tobacco aroma from an aerosol-forming article comprising tobacco material. The release of harmful chemicals from the smoke upon heating is significantly reduced compared to conventional cigarettes.

The invention patent application entitled "a typical heated non-combustible smoking article and apparatus", filed in china by philips morris corporation under application number 201580022463.7, comprises a heating element for receiving a tubular portion of an aerosol-forming article and an end face, the heating element being positioned at one end of the tubular portion such that the end face is proximate to one end of the aerosol-forming article when the aerosol-forming article is inserted into the tubular portion.

The invention patent application entitled "a typical heat-not-burn smoking article", filed in china by philips morris corporation under application number 201280061528.9, includes: an aerosol-forming substrate, a support element disposed immediately downstream of the aerosol-forming substrate, an aerosol-cooling element disposed downstream of the support element, and an outer wrap circumscribing the aerosol-forming substrate, the support element, and the aerosol-cooling element; the support element abuts the aerosol-forming substrate; the aerosol-forming substrate is penetrable by the heating element of the aerosol-generating device.

Both of the above patents are typical of the construction of a heated non-burning cigarette and smoking set by philips morris corporation. It is obvious that the non-burning cigarette manufactured by Philippi Morris company is composed of a tobacco base body, a supporting element, a cooling element and a filtering element in sequence, and adopts a disposable design. The smoking mode is that a tobacco substrate section of the non-combustible cigarette is inserted into a tubular part of the smoking set, which is close to the heating element, and when the tobacco substrate is heated to release smoke, a smoker smokes the cigarette by heating the filter element at the other end of the non-combustible cigarette. Because the heating end of the smoking set is adjacent to the suction end, the heating end is close to the mouth of the smoker, and the cigarette needs to be designed with a cooling element which is made of polylactic acid material, and the smoke with higher temperature can cause the polylactic acid material to release harmful substances. Even if the smog is cooled through the cooling element, the mouth of a smoker can still be scalded by the temperature of the heating end of the smoking set, harmful substances are released rarely due to heating of the non-combustible smoking set, the disposable filtering element is not used until the service life is finished, the disposable filtering element has to be discarded along with a cigarette, resource waste and environmental pollution are caused, and meanwhile, the smoking mode can only be used for smoking through the smoking set held by the smoker, and the smoking experience is poor.

The invention discloses a smoking device and a smoking method for heating non-combustible cigarettes, which are applied by technologies and technologies Limited company in Qingdao Yizhong and tobacco industry Limited liability company in Zhejiang, and have the application number of 201710945367.4.
