Heat-not-burn smoke cartridge with binary structure

Abstract

The invention relates to a heat-not-burn smoke cartridge with a binary structure. The heat-not-burn smoke cartridge is formed by sequentially connecting a smoke generation section (1) and a smoke constraint section (2) in a wrapping and twisting mode through outer-layer wrapping paper (3). According to the heat-not-burn smoke cartridge, in the smoking process, the smoke generation section makes contact with a heating element of the heater, smoke is released and flows through the smoke constraint section, the effects of reducing the smoke temperature and guiding smoke are achieved, and cooled high-concentration smoke is transmitted to the oral cavity of a consumer; the heat-not-burn smoke cartridge has the advantages of being high in smoke generating amount and low in smoke temperature and the like; and the heat-not-burn smoke cartridge is simple in structure and easy to industrialize, and has a very good industrial application prospect.

Description

[0001] The present invention claims the priority of the Chinese invention patent application with the application date of October 30, 2020 and the application number CN2020111851050. 【Technical field】 [0002] The invention belongs to the technical field of tobacco processing. More specifically, the present invention relates to a heat-not-burn pod with a binary structure. 【Background technique】 [0003] Heat-not-burn products are a new type of product developed in recent years. Due to the use of an external heat source to heat and bake to release smoke, the release of harmful components in the product is significantly reduced. Compared with traditional smoking tobacco, the safety of the product has been significantly improved. improvement. Combined with specific advantages such as rich flavors, no flue gas, and no soot pollution, heat-not-burn tobacco products have been recognized in the market and have achieved good market feedback. At present, the annual sales scale of p...

Problems solved by technology

[0004] However, due to the technical solution of heating and baking to release smoke, these products generally have experience defects of insufficient smoke concentration and high smoke temperature. These defects also limit more consumers to choose heat-not-burn products

Heat-not-burn products often use multi-component composite filter rods to regulate the concentration and temperature of flue gas. However, due to technical problems in related material selection and structural design, this problem cannot be effectively solved. At present, the flue gas of heat-not-burn products is generally The total particle phase is not higher than 18mg / piece, and the temperature of the flue gas and the surface of the filter is higher than 45°C

At the same time, the complex filter rod structure leads to difficulties in product manufacturing and high production costs. For example, US20140305448A1, the title of the invention "Aerosol Generating Products Used with Aerosol Generating Devices", discloses a heat-not-burn pod with a quaternary structure , its quaternary structure is respectively a smoking section, a support section, a cooling section and a filtering section. Disadvantages such as high air temperature; CN110680018A, the invention name "support for incense core and incense core with it" discloses a ternary structure heat-not-burn pod structure in the embodiment, which are respectively the smoke section, the resistance The high-temperature flue gas channel section and the filtering section simplify the pod production process and reduce the flue gas temperature to a certain extent, but the smoke generation in the filtering section is still relatively low, which does not solve the pain point of high smoke concentration; CN211153800U, invention name " A heat-not-burn cigarette and smoking product" discloses a heat-not-burn cigarette and a smoking product, the heat-not-burn cigarette includes a matrix section, a gas mist collection section circulation element and an outer wrapping element, the matrix The section includes the aerosol generation section and the aerosol passage section. When the smoke passes through the aerosol passage section, it will absorb part of the aroma and smoke, which will affect the release of aroma and reduce the smoke concentration. The aerosol collection section is composed of acetate fiber tube, polylactic acid tube, paper One or more components in the tube, the material selected for the aerosol collection section does not have a very obvious cooling effect in practical applications, which can be seen from the test data of the embodiment of this invention, and it cannot specifically solve the problem of the amount of smoke and smoke The contradiction between the two of the concentration; CN210581038U, title of invention "composite aerosol circulation rod, aerosol circulation product and aerosol circulation system" discloses a composite aerosol circulation section heat-not-burn product, composed of a composite aerosol circulation section and a smoke section The composite aerosol composite section is composed of two cylinders made of acetate fiber tow or polylactic acid tow with through holes. From the effect of the embodiment, the smoke concentration has been improved to a certain extent, but the temperature of the smoke is at Above 42°C, the problem of smoke concentration is solved, but the problem of high smoke temperature is not solved
