The filter tip consists of a filter tip section and an aerosol generation section, and is characterized in that the filter tip section consists of a paper tube A and a filter stick unit filled in the paper tube A; the aerosol generation section consists of a paper tube B, tobacco sticks filled in the paper tube B in sequence and a porous reducing cooling unit; the invention uses the combination formed by microwave expansion recombined tobacco shreds, expanded tobacco shreds and dry tobacco sheets as the smoking material, thereby greatly improving the utilization rate of the conventional tobacco raw materials in heating non-combustible tobacco products. Meanwhile, the effective combination enables the suction effect of the product to be better.
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 a two-section type aerosol generating product and a preparation method thereof.
Background
Various forms of aerosol-generating articles have been proposed in the known art, these articles being characterised by heating, but not burning, tobacco, generally at temperatures below 350 ℃, with 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 becoming a hotspot of current research.
Smoking materials for existing heat non-combustible tobacco products are largely classified into homogenized tobacco sheet and pellet types. The homogenized tobacco sheet material is mainly produced and manufactured by thick liquid method, rolling method, dry method and paper making method; the granular smoking material is produced by mechanically granulating tobacco material or plant stems.
Neither homogenized tobacco sheets nor particles as aerosol-generating substrates for producing heat-not-burn tobacco products can utilize the existing cigarette making and connecting units in the tobacco industry, but special production and processing equipment must be developed to meet production requirements, thereby increasing the comprehensive input cost.
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 performance of absorbing fluid substances containing volatile compounds is poor, the released smoke quantity is small, and the smoking temperature is high, so that an ideal using effect cannot be brought in the actual application process.
The existing heaters are divided into an insertion type heating mode and a non-insertion wrapping type heating mode, and most of the mainstream heaters in the market adopt the insertion type heating mode. The plug-in heating is performed in such a manner that a pin-type or chip-type heating body is inserted into the smoking material. If the base material generated by the aerosol is filamentous, after the smoking of a consumer is finished, coked smoking materials in cigarettes can be adhered to the needle-type or sheet-type heating body, so that peculiar smell is generated during secondary smoking, and more harmful ingredients can be released. If the base material that aerial fog generated is the filiform fuming material of relatively fine crushing, it can drop in the heating cavity of heater at the in-process that cigarette was pulled out for it is very inconvenient to clean, has reduced user experience and product security.
The cigarette that is different from axial arrangement's thin slice smoking material to form, the cigarette is not burnt in the heating of known mixed preface winding tobacco silk form, because cigarette inserts the one section parcel of heater and adopts the bobbin stock or compound bobbin stock that has the aluminium foil, stress is relatively poor, can not provide great holding power at the in-process that inserts the heating member, produce deformation easily, thereby the smoking article that leads to cigarette to prop up the front end is extremely easy to push backward and crowd the deformation, cause the aerial fog passageway to block up, make cigarette to inhale and hinder the grow, the consumer will unable aerial fog that the capacity is heated of sucking.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a two-section type aerosol generating product and a preparation method thereof.
The invention is realized by the following technical scheme:
a two-section type aerosol generating product consists of a filter tip section and an aerosol generating section, wherein the filter tip section consists of a paper tube A and a filter rod unit filled in the paper tube A; the aerosol generation section consists of a paper tube B, tobacco sticks filled in the paper tube B in sequence and a porous reducing cooling unit; a hollow unit is reserved in the paper cylinder A and/or the paper cylinder B; the end face of one end of the paper tube B filled with the tobacco strips is provided with a sealing sheet; the diameter of the paper tube A is equal to that of the paper tube B, one end of the non-filter stick unit of the paper tube A is tightly butted with one end of the non-sealing sheet of the paper tube B, and the non-filter stick unit of the paper tube A and the non-sealing sheet of the paper tube B are wrapped and connected into a whole through tipping paper.
The paper tube A and the paper tube B are both cylindrical hollow paper tubes which are made by coating 2-5 layers of paper tapes with the gram weight of 50-200g with white latex on the inner sides and winding in a spiral twisting and forming manner; the thickness of the paper tube A and the thickness of the paper tube B are both 0.2-0.5mm, and the diameter of the paper tube A and the diameter of the paper tube B are both 6-9 mm; the length of the paper tube A is 10-20mm, and the length of the paper tube B is 15-30 mm. The white latex is polyvinyl acetate adhesive, which is called PVAC emulsion for short.
The sealing sheet is made of paper materials, is in a disc shape, has the diameter equal to the outer diameter of the paper tube B, and covers the end face of one end of the paper tube B in a sticking mode. The glue for bonding the sealing sheet and the end face of the paper tube can adopt cigarette glue prepared by modifying PVAC emulsion or VAE emulsion. Meanwhile, in order to ensure good air permeability, the sealing sheet is preferably made of paper with high air permeability.
In some specific embodiments, in order to prevent oily substances contained in the smoking material from permeating and transferring to the sealing sheet when contacting the sealing sheet to influence the appearance of the cigarette, one side of the sealing sheet is also coated with environment-friendly gloss oil.
The sealing piece can also have other forms, and particularly, the sealing piece is provided with a fastening ring, and the sealing piece is externally covered/embedded at one end of the paper tube through the fastening ring.
