Abstract

Le présent modèle d'utilité concerne un couvercle rotatif, qui comprend un couvercle supérieur et un couvercle rotatif. Le bord du couvercle supérieur est formé de façon concave le long de la circonférence en un bord convexe pour former ensuite une structure du type couvercle. Le couvercle rotatif est fixé en rotation sous le milieu du couvercle supérieur et à proximité du couvercle supérieur pour mettre en œuvre la rotation coaxiale du couvercle rotatif et du couvercle supérieur. Le couvercle rotatif fait saillie vers le haut pour présenter une certaine courbure sphérique, et le couvercle supérieur dans la région où se trouve le couvercle rotatif présente également une courbure sphérique correspondante. Un premier trou traversant est fourni sur le couvercle rotatif, un second trou traversant présentant la même forme que le premier trou traversant est disposé sur le couvercle supérieur, et le premier trou traversant coïncide avec le second trou traversant. Dans le présent modèle d'utilité, le couvercle rotatif est fixé en rotation sur la surface inférieure du couvercle supérieur d'un appareil de chauffage en tant que surface de barrière pour un rayonnement de chaleur de bas en haut dans l'appareil de chauffage. La totalité de sa surface fait saillie vers le haut pour présenter une courbure sphérique, et par conséquent, le couvercle supérieur fait également saillie dans la même direction pour présenter une courbure sphérique, ce qui peut empêcher efficacement le problème selon lequel le couvercle rotatif ne peut pas être tourné du fait d'une déformation thermique.
