A rear intake type heat conduction smoking device

Abstract

The invention discloses a rear air-intake heat conduction smoking device, which comprises an inner heat conduction shell, an outer heat conduction shell sleeved outside the inner heat conduction shell, and an air intake interlayer is formed therebetween; the end of the inner heat conduction shell and the outer heat conduction shell An airflow inlet is formed between the ends of the heat conduction shells. The closed end of the outer heat conduction shell is the heating part. There is a gap between the heating part and the air inlet of the inner layer. Set has fuel section. In the present invention, the opening of the airflow channel is rearranged so that it is separated from the fuel part by one end. This setting can achieve the effect of basically isolating the intake air from the exhaust gas generated by the fuel, and widens the range of use of the fuel formulation. The structure of the invention greatly improves the dry distillation effect, separates the opening of the air flow passage from the fuel combustion part, and expands the use range of the fuel.

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
