Device for heating cigarettes

Abstract

The invention belongs to the field related to cigarette processing, and relates to a cigarette heating device which can be used for heating or baking cigarettes, in particular to a tubular heating device for heating cigarettes, which can heat cigarettes and emit a large amount of smoke. A cigarette heating apparatus includes a heating tube, A lumen inside that heat tube is a heating lumen, At least one set of thread grooves is arrange on that outer wall of the heating pipe, a set of heating wire matched with the threaded grooves is wound on each set of threaded grooves, each set of heating wire is controlled by an independent circuit, the heating wire is wrapped by an insulating and heat conductive material, and the heating pipe is made of a heat conductive material. The device has the advantages of strong applicability, simple manufacturing process, convenient assembly and maintenance, more uniform heating and higher heat transfer efficiency.

Description

technical field [0001] The invention belongs to the field related to cigarette processing, and relates to a cigarette heating device, which can be used for heating or curing cigarettes. Specifically, it relates to a tubular heating device for heating cigarettes. smoke. Background technique [0002] Although the number of smokers has decreased in recent years, there is still a sizeable population of smokers in the world who smoke through smoking devices including cigars, pipes, hookahs and tobacco heating devices. Traditional smoking needs to be ignited. The temperature of tobacco is as high as 1000°C. Tar is produced at 500-900°C. It is a mixture that carries most of the harmful substances in cigarettes. Medical research has proved that tar is a carcinogen and can induce mutations in human cells. , Inhibition of human immune function, benzene, tea, pyrene, phenol and other carcinogens are generated at 700-900°C, and carcinogens such as phenols and fumaric acid are generated...

AI Technical Summary

Problems solved by technology

However, the contact area between the heating wire and the heating chamber of this heating method is small, the heat conduction efficiency is low, and part of the heat cannot be transferred to the tobacco in time, and the electric heating element may move and shrink together after repeated heating or high-temperature baking, which will cause Lead to uneven heating, local high temperature and even burning
