Abstract

L'invention concerne un dispositif de chauffage pour chauffer un milieu pour former un système de dispersion de gaz comprenant un tube de chauffage (1). Un corps de tube du tube de chauffage (1) est divisé en une première partie de chauffage (11) et une seconde partie de chauffage (12) par une bande de régulation thermique continue (13). La bande de régulation thermique (13) a une forme de boucle fermée continue sur une surface du corps de tube, et est située dans un plan incliné unique. Le plan incliné est incliné par rapport à un plan axial et une section transversale du corps de tube. Une électrode de première partie de chauffage (111) est disposée sur la première partie de chauffage (11). Une électrode de seconde partie de chauffage (121) est disposée sur la seconde partie de chauffage (12). Des électrodes communes (112, 122) sont disposées sur la bande de régulation thermique (13). Les électrodes communes (112, 122) connectent la première partie de chauffage (11) et la seconde partie de chauffage (12) l'une à l'autre, et sont respectivement connectées aux électrodes sur les deux parties de chauffage de façon à être connectées à un circuit de chauffage, de telle sorte que la première partie de chauffage (11) et la seconde partie de chauffage (12) génèrent de la chaleur indépendamment. Le tube de chauffage (1) a un processus d'usinage simple, et a une variété de procédés de commande pour un chauffage spécifique à une région, ce qui permet d'améliorer l'efficacité du tube de chauffage (1) pour chauffer un milieu de formation de fumée interne, et d'améliorer l'expérience utilisateur d'un appareil à fumer à basse température.
