Detailed Description
The present invention is described below based on embodiments, and it will be understood by those of ordinary skill in the art that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.
Unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, what is meant is "including, but not limited to".
The axis of pot cover described in this application is promptly when cooking utensil is in normal state of placing with horizontal plane vertical line, the axial inboard of pot cover is close to the inside one side of cooking utensil pot body promptly, and the axial outside is kept away from the inside one side of cooking utensil pot body promptly. All the orientation words mentioned in the present application are the orientations of the cooking vessel in normal use.
The application provides a pot cover for cooking utensil, as shown in figure 1, it includes face lid (not shown in the figure), inner cup subassembly 1, pot tooth circle (not shown in the figure) and apron subassembly 3 in proper order to the axial inboard from the axial outside of pot cover, and float 4 sets up on apron subassembly 3 to can float under the internal pressure effect of pot of cooking utensil. Wherein, inner cup subassembly 1 includes inner cup 11 and rotationally sets up the rotatory structure 12 of uncapping on inner cup 11, rotatory structure 12 of uncapping is including rotating main part 121 and setting up the connecting rod 122 on rotating main part 121, preferably, it is cylinder or round platform form approximately to rotate main part 121, connecting rod 122 an organic whole is formed at the radial outside that rotates main part 121, rotatory structure 12 of uncapping links to each other with the tooth circle of a boiler through connecting rod 122, when rotatory structure 12 of uncapping rotates, it can drive connecting rod 122 and the synchronous rotation of the tooth circle of a boiler that links to each other with connecting rod 122, realize the locking and the unblock of the tooth circle of a boiler and pot body. In this application, the direction of rotation of rotating the structure 12 of uncapping when locking the tooth circle with the pot body defines for closing the lid direction, and the direction of rotation of rotating the structure 12 of uncapping when unblocking the tooth circle with the pot body defines for uncapping the direction.
