Rear air inlet type heat-conducting smoking device

Abstract

The invention discloses a rear air inlet type heat-conducting smoking device. The heat-conducting smoking device comprises an inner heat-conducting casing and an outer heat-conducting casing nested outside the inner heat-conducting casing, wherein an air inlet interlayer is formed between the inner heat-conducting casing and the outer heat-conducting casing; an airflow inlet is formed between the end part of the inner heat-conducting casing and the end part of the outer heat-conducting casing, a closed end of the outer heat-conducting casing is a heating part, a gap is formed between the heating part and an inner air inlet, and the air inlet interlayer and the gap are communicated to form an airflow passage; and the outer surface of the heating part is sleeved with a fuel part. According to the invention, an opening of the airflow passage is formed in the rear so as to form a certain distance with the fuel part, with the adoption of the arrangement, inlet air is basically isolated from waste gas generated by fuel, and the formula application range of the fuel is broadened; and with the adoption of the structure of the heat-conducting smoking device, the dry distillation effect is greatly improved, the opening of the airflow passage and the burning part of the fuel are isolated, and the application range of the fuel is extended.

Description

technical field [0001] The invention relates to the field of cigarettes, in particular to an external heat-conducting smoking device with rear air intake. Background technique [0002] Studies have shown that nicotine and most tobacco flavor components can be transferred to smoke at lower temperatures (300-500°C). If the temperature of the cigarette is lowered to below 600°C (the ignition point of tobacco is about 700°C), various harmful components of the smoke can be greatly reduced, while the aroma components are relatively less affected. Therefore, a kind of cigarette that utilizes carbonaceous heat source to carry out dry distillation tobacco component is invented. The existing technology is to reserve a longitudinal groove on the extruded carbon rod, so that the air can be heated when it flows through the surface of the carbon rod. The flue gas inhales more CO; if the fuel is placed outside the airflow channel, the fuel will not get sufficient oxygen supply during suc...

AI Technical Summary

Problems solved by technology

The existing technology is to reserve a longitudinal groove on the extruded carbon rod, so that the air can be heated when it flows through the surface of the carbon rod. The flue gas inhales more CO; if the fuel is placed outside the airflow channel, the fuel will not get sufficient oxygen supply during suction, and it is not easy to ignite, and because the front air intake method is too close to the fuel, from the perspective of safety, Limits the use of combustion accelerants
