[ summary of the invention ]
[ problem to be solved ]
The invention aims to provide a unit for cooling cigarettes which are not combusted during heating.
[ solution ]
The invention is realized by the following technical scheme.
The invention relates to a cigarette cooling unit capable of heating and non-burning cigarettes.
The cigarette cooling unit without burning is a foaming material base rod 2 with melting point of 400-800 ℃ and porosity of a pore 201 of 40-95% and loaded with a fragrant substance, or a foaming material base rod 2 with an outer surface coated with a layer of forming paper 1.
According to a preferred embodiment of the invention, in the unit for cooling the cigarette without burning, the foaming material is silica gel, polylactic acid, polyurethane, polyethylene or acetate fiber for the cigarette.
According to another preferred embodiment of the present invention, the base rod 2 of the foamed material is a solid base rod having a triangular, pentagonal, square, parallelogram or circular cross section, or a hollow tubular base rod having a triangular, square or circular cross section and a circular outer wall.

According to another preferred embodiment of the present invention, in the foamed material, the porosity of the pores 201 is 52 to 80%.
According to another preferred embodiment of the present invention, the melting point of the foaming material is 500 to 680 ℃.
According to another preferred embodiment of the present invention, the density of the foamed material is 0.6 to 1.2g/cm3。
According to another preferred embodiment of the invention, the specific heat capacity of the foamed material is 1.0 × 103～3.2×103J/(kg·℃)。
According to another preferred embodiment of the invention, the amount of the aroma substances carried by the foaming material is 5-10% of the total weight of the cigarette cooling unit without burning.
According to another preferred embodiment of the invention, said aromatic substance is a floral, mint, fruit or tobacco type essence.
The present invention will be described in more detail below.
The invention relates to a temperature reduction unit for heating non-combustible cigarettes, which is shown in the attached drawings 1-3.
The cigarette cooling unit without burning is a foaming material base rod 2 with melting point of 400-800 ℃ and porosity of a pore 201 of 40-95% and loaded with a fragrant substance, or a foaming material base rod 2 with an outer surface coated with a layer of forming paper 1.
In the foam material, the porosity of the pores 201 is 40-95%. The porosity is measured according to GB/T21650.3-2011 mercury intrusion method and a gas adsorption method, and the porosity is part 3: gas adsorption analysis of micropores. In the invention, the reasonable porosity can effectively reduce the energy exchange caused by air convection, so that the heat is kept in the smoke generating section and the energy consumption is reduced. If the porosity of the foaming material is lower than 40%, the cigarette resistance is increased, the smoking experience is affected, and if the porosity of the foaming material is higher than 90%, the cooling effect of the cooling unit is greatly reduced, so that the porosity of 40-90% is reasonable, and preferably 52-80%.
The smoke temperature is above 200 ℃ in the smoking process of heating the non-burning cigarette, so the cooling material should have certain heat resistance. The melting point of the foaming material is 400-800 ℃. The melting point is according to GB/T19466.4-2016 plastics Differential Scanning Calorimetry (DSC) part 3: melting and crystallization temperatures and enthalpy. If the melting point of the foaming material is lower than 400 ℃, the material can be subjected to thermal collapse or melting during suction, so that the smoothness of suction is influenced, the cooling effect is seriously lost, and the suction experience is influenced; if the melting point of the foaming material is higher than 800 ℃, the material is hard, high energy consumption is needed during pore forming, and the material is not easy to cut during filter stick forming; therefore, the melting temperature of the foaming material used in the invention is reasonable to be 400-800 ℃, and preferably 500-680 ℃.
In the present invention, the main purpose of examining the density of the foamed material is to control the quality of the cooling section. The density of the foaming material is 0.6-1.2 g/cm3. The density is determined according to the density determination method of ISO 1183 plastic and non-foam plastic. If the density of the foamed material is less than 0.6g/cm3The cooling section is lighter and is easy to break; if the density of the foamed material is higher than 1.2g/cm3The temperature reduction section is heavy, so that the weight of the whole cigarette is increased, and the smoking experience is influenced; therefore, the density of the foam material is 0.6 to 1.2g/cm3Is suitably, preferably 0.8 to 1.1g/cm3；
The specific heat capacity is a physical quantity commonly used in thermodynamics and represents the heat absorption or dissipation capacity of an object, and the larger the specific heat capacity, the stronger the heat absorption or dissipation capacity of the object, which is understood to be the amount of heat absorbed or released per unit mass of a substance at an elevated or reduced temperature, the specific heat capacity of the foamed material of the present invention is 1.0 × 103～3.2×103J/(kg. DEG C.) said specific heat capacity is determined according to the standard method for determining the specific heat capacity of GB/T19466.4-2016 Plastic differential scanning calorimetry DSC part 4. if the specific heat capacity of the foamed material is lower than 1.0 × 103J/(kg. DEG C.), the heat absorbed by the cooling section per unit weight is smaller, which causes the smoke to be scalded, if the specific heat capacity of the foaming material is higher than 3.2 × 103J/(kg DEG C), the cooling section of unit weight absorbs more heat, the cooling section is in a condensation state, the moisture content in the smoke is reduced, and the smoke is dried, so the specific heat capacity of the foaming material is 1.0 × 103～3.2×103J/(kg. DEG. C.) is appropriate;
in the cigarette heating and non-burning cooling unit, the foaming material is silica gel, polylactic acid, polyurethane, polyethylene or acetate fiber for cigarettes. These foamed materials are food grade and are currently marketed products such as silica gel sold under the trade name silicone rubber by reinzhen renbo rubber products ltd, polylactic acid sold under the trade name PLA by zhejiang sea biomaterial ltd, polyurethane sold under the trade name polyurethane by ningjin de ru polyurethane products ltd, polyethylene sold under the trade name high density polyethylene by deluxe rubber plastic products ltd, cellulose acetate sold under the trade name cellulose acetate resin by kunming cellulose acetate ltd.
According to the invention, the amount of the aroma substances carried by the foaming material is 5-10% of the total weight of the cigarette cooling unit without burning during heating. If the amount of the aroma substances carried by the foaming material is less than 5%, the aroma carrying amount is small, and the aroma substances are not easy to perceive during smoking; if the amount of the aroma substances carried by the foaming material is higher than 10%, the aroma carrying amount is too high, other aromas are covered, and the smoking quality is influenced; therefore, the amount of the odoriferous substance carried by the foam is suitably 5 to 10%, preferably 6 to 8%;
in the present invention, the fragrant substance is a floral, mint, fruit or tobacco type essence, which are commonly used in the art. Floral essences are, for example, osmanthus fragrans, gardenia, burma osmanthus fragrans or peony essence; mint-based flavors such as spearmint, peppermint or peppermint flavors; fruit essences are, for example, apple, papaya, Hami melon or passion fruit essences; tobacco-based flavors are, for example, burley, flue-cured, cigar or sun-cured yellow tobacco flavors.

The foam material base rod 2 is manufactured by adopting the existing processing method, and the specific reference is as follows: the publication of the chemical industry press (2008) is published by "New Polymer foams and techniques".
According to the invention, the outer circumference of the foam material base rod 2 or the foam material base rod 2 wrapped with the forming paper is the same as the circumference of the cigarette.
The method for producing the cigarette without heating and burning by using the foaming material base rod 2 comprises the following steps:
according to the expected cigarette structure, the foaming material base rod 2 or the foaming material base rod 2 wrapped by the forming paper is cut into the cooling section meeting the requirement by using a cutter, and then the cooling section is compounded with the existing filtering section and the heating section by using cigarette equipment to obtain the non-combustible heating cigarette.
