Phase-change temperature control type fuel assembly for non-combustion type low temperature cigarette and preparing method thereof

Abstract

The invention relates to a phase-change temperature control type fuel assembly for a non-combustion type low temperature cigarette and a preparing method thereof. The fuel assembly comprises a fuel element and a fuel element embedding sleeve. The fuel element is made of carbonaceous raw materials which include the bamboo carbon and the cryptocrystalline graphite. The fuel element embedding sleeve is arranged outside the fuel element in a sleeving mode. An annular cavity is formed between the fuel element embedding sleeve and the fuel element. According to the fuel assembly and the preparing method, a method for controlling the excessively-high temperature output of the fuel element through phase-change heat storage materials, and in the free space which is located between the inner surface of the embedding sleeve and the outer surface of the fuel element and forms the annular cavity, adsorption, oxidation and catalysis are carried out on CO under the thermo-electric effect of tourmaline and the electrostatic effect and the adsorption effect of a self-power-generation electrode. By means of the fuel assembly and the preparing method, the combustion performance and the safety performance of the fuel element and the manufacturing efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of new tobacco, in particular to a carbonaceous heat source for non-combustible low-temperature cigarettes, and in particular to a phase-change temperature-controlling carbonaceous fuel assembly and a preparation method thereof. Background technique [0002] In recent years, new tobacco products have shown a rapid development trend. The reasons are: on the one hand, the consumption population ratio of traditional tobacco products is declining year by year; Many countries have formulated and implemented strict bans on smoking in public places. In this context, new tobacco products can not only better adapt to the ban on smoking in public places, but also satisfy the personal preferences of tobacco consumers to a certain extent, so the market demand is growing rapidly. [0003] The main features of the so-called new tobacco products are that they do not need to burn tobacco, and significantly reduce the harmf...

Problems solved by technology

[0055] It is particularly worth noting that these Chinese patent applications CN103889254A, CN104105419A, CN103619198A, CN103929984A of Philip Morris Production Company, and the possible problems of Chinese patent CN200880102333.8 are: since the suction airflow is basically isolated from the combustible heat source, on the one hand The degree of correlation between the oxygen required for the combustion of the heat source and the suction airflow is greatly reduced, which requires that the heat source can spontaneously and stably obtain oxygen from the outside air and the combustion aid contained in it during the combustion process, so that the combustion of the combustible heat source Composition and structure (e.g. porous) become somewhat complex

Therefore, the component design of the fuel element has been balanced with many influencing factors, making its composition and process more complex. Although this is due to the success of technology, some people are facing "is it too complicated to be artificial or relatively simple?" There may be some hesitation when choosing the question "Natural"
