Description
Technical Field
The invention belongs to the technical field of novel tobacco, particularly relates to a cigarette structure for heating a non-burning tobacco product, and further discloses an aerosol generating product with a binary structure and a preparation method thereof.
Background
Various forms of aerosol-generating articles have been proposed in the known art, these articles being characterised by a heated but non-combustible tobacco product, the heating temperature of which is generally below 350 ℃, and only a small amount of second-hand smoke being generated during the heating of the aerosol-generating article, the resulting aerosol being less harmful, and being the focus of current research.
The existing smoking materials of heating non-combustible tobacco products are mainly divided into flake type and particle type. The homogenized tobacco sheet material is mainly manufactured and produced by thick liquid method, rolling method, dry method and paper making method; granular smoking materials are produced by granulating tobacco materials or stems and fruits of plants.
In either homogenized tobacco sheets or heated non-combustible tobacco products with particles as aerosol generating materials, special equipment must be developed for production and processing, and the tobacco products cannot be processed and manufactured by the existing cigarette making and connecting machine set in the tobacco industry, so that the comprehensive investment cost is increased.
Related products are known to use cut tobacco and expanded cut tobacco as smoking materials of heating non-combustible tobacco products, but due to the characteristics of the structure of the cut tobacco, the property of absorbing fluid substances containing volatile compounds is poor, so that the released smoke quantity is small, the smoking temperature is high, and ideal use effects cannot be brought in the actual application process.
The existing heaters are divided into plug-in type heating and non-plug-in package type heating, and the mainstream heaters in the market are plug-in type heating. The plug-in heating is realized by adopting a mode that a needle-type or sheet-type heating body is inserted into a smoking material for heating, if a base material generated by aerosol is a bent filament-shaped material which is wound in an overlapping mode, after smoking is finished by a consumer, a coked smoking material in a cigarette can be adhered to the needle-type or sheet-type heating body, so that peculiar smell and more harmful ingredients are released during secondary smoking; and some relatively fine and broken filiform smoking materials can drop in the heating cavity of the heater in the process of pulling out the cigarette, so that the cigarette is extremely inconvenient to clean, and the user experience and the product safety are reduced.
Different from the cigarette that the tobacco sheet smoking material of axial arrangement formed, the cigarette is not burnt in the heating of the known mixed preface winding tobacco silk form, because cigarette inserts the wrapping material of heater one section and is coil paper or compound coil paper that has the aluminium foil, stress is relatively poor, can not provide great holding power at the in-process of inserting the heating member, produce deformation easily, thereby it is extremely easy backward to push the deformation to lead to the smoking product of cigarette front end, thereby lead to blockking up the aerial fog passageway in the cigarette, make cigarette draw and hinder the grow, the consumer will be less or can't suck the aerial fog that is heated.
