When the kettle is folded, the folding support rod 201 is embedded after being folded towards the central axis direction of the kettle body 2, and when the kettle is unfolded, the folding support rod 201 plays a role in supporting the kettle body 2. The inner bag 202 is made of soft waterproof heat-resistant food-grade environment-friendly material, is partially or completely made of soft material, and is connected with the kettle bottom 3 at the lower end and provided with an opening at the upper end. The existing kettle has the function of supporting the whole kettle after the soft kettle body is unfolded, the kettle body needs to be thicker, the volume is relatively smaller, and otherwise, the risk of collapse can be caused. According to the folding kettle, the folding support rod is vertically arranged around the inner bag, the upper end and the lower end are directly or indirectly hinged with the kettle bottom and the upper connecting sleeve respectively, and the folding kettle can play a role of supporting the whole kettle after being straightened, so that the inner bag can be relatively thin, the capacity design of the kettle can be increased, and the safety of the kettle is guaranteed; the folding support rod can be turned and folded from the middle when being folded, the soft bag can be pushed to the middle to be folded when being folded, and dislocation disorder can not be caused when the soft bag is folded. Further, as shown in fig. 6 to 7 and 14 to 17, the folding support rod 201 includes an upper section support rod 201a and a lower section support rod 201b, the upper section support rod 201a and the lower section support rod 201b are hinged by a second hinge 201d, and any one of them is a hollow structure, i.e. is provided with a receiving groove 201g, and after the folding support rod is folded in half, the upper section support rod 201a and the lower section support rod 201b can be inserted into the receiving groove 201g for receiving. The advantages of the above design are: the folding support rod is divided into an upper section support rod and a lower section support rod, then the middle of the folding support rod is connected together through a hinge, and the two ends of the folding support rod are respectively hinged to the kettle bottom and the upper connecting sleeve, so that the folding support rod can be smoothly folded when being conveniently folded, and the folding support rod has a simple structure, high durability and high reliability; the first hinge and the third hinge can limit the folded support rod to rotate 90 degrees only towards the center direction of the kettle, so that the phenomenon of reverse folding caused by over rotation is avoided; the second hinge can also limit the kettle to rotate 180 degrees towards the center direction of the kettle, and the first hinge and the third hinge are matched to rotate, so that reverse folding is avoided.
