The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the application, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
As shown in fig. 1 and 2, the pressure limiting valve assembly of the pressure cooker of the present embodiment includes a pressure limiting valve body 10 and a weight 20. The weight member 20 is disposed outside the pressure limiting valve body 10, and the weight member 20 includes a cylinder 21 and a cover 22 detachably disposed above the cylinder 21. An anti-drop structure 30 is arranged between the pressure limiting valve body 10 and the barrel part 21. The anti-slip structure 30 is used for preventing the pressure limiting valve body 10 from falling out of the barrel 21, and the cover body 22 is arranged on the barrel 21 and prevents the pressure limiting valve body 10 from falling out of the barrel 21.
By applying the technical solution of this embodiment, the weight member 20 is divided into a barrel 21 and a cover 22 which are detachable from each other. Meanwhile, the anti-drop structure 30 and the cover 22 can limit the position of the pressure limiting valve body 10 in the barrel 21 after installation, and have an anti-drop effect. The structure enables a thread structure between the balancing weight 20 and the pressure limiting valve body 10 not to be processed, and the processing technology is simple and the cost is low. Therefore, the technical scheme of the embodiment solves the problems that the pressure limiting valve and the balancing weight of the electric pressure cooker in the prior art are complex in processing technology and high in production cost.
Referring to fig. 1, it should be noted that the barrel 21 in this embodiment is a sleeve structure composed of an annular sidewall. The lid portion 22 includes an annular side wall and a top wall. Of course, in an embodiment not shown, the cover 22 may be formed of only one top wall.
As shown in fig. 3 and 4, in the solution of the present embodiment, the anti-separation structure 30 includes a first stop flange 31 disposed on the outer side wall of the pressure limiting valve body 10 and a second stop flange 32 disposed on the inner side wall of the barrel portion 21, and the outer diameter of the first stop flange 31 is larger than the inner diameter of the second stop flange 32, so that the second stop flange 32 is stopped below the first stop flange 31. Specifically, the first stopper bead 31 and the second stopper bead 32 are both annular beads, and the above structure prevents the first stopper bead 31 from passing through the second stopper bead 32 downward, thereby achieving a downward anti-slip effect.
As shown in fig. 3, in the solution of the present embodiment, the first stopping flange 31 is provided with a notch 311, and water can flow downward along the gap between the second stopping flange 32 and the pressure limiting valve body 10 after passing through the notch 311.

The first groove section 421 extends in a direction parallel to the central axis of the cover portion 22, and a first end of the first groove section 421 penetrates through a lower end surface of the side wall of the cover portion 22 and forms an opening. The second groove segment 422 extends along the circumferential direction of the cover portion 22, a first end of the second groove segment 422 is connected to a second end of the first groove segment 421, and a second end of the second groove segment 422 extends toward a direction away from the first groove segment 421. When the barrel portion 21 and the lid portion 22 are assembled, the coupling projection 41 is inserted into the first groove section 421 through the opening, the coupling projection 41 slides in the first groove section 421 toward the second groove section 422, and then the coupling projection 41 slides in the horizontal direction and is inserted into the second groove section 422. Through the above-described assembling process, the relative position in the axial direction between the barrel portion 21 and the lid portion 22 can be fixed. Of course, the above-mentioned locking groove 42 may have other shapes, for example, the locking groove 42 is a groove structure that is provided on the inner wall of the cover body 22 and matches with the shape of the connecting protrusion 41, and the connecting protrusion 41 is locked into the locking groove 42 by elastic deformation during assembly.
