As shown in fig. 1 to 5, a pot cover assembly comprises a cover body 1 and an anti-overflow valve 2, wherein the cover body 1 is provided with a backflow port 13 communicated with a cooking cavity, the anti-overflow valve 2 is arranged at the backflow port 13, the anti-overflow valve 2 comprises a supporting part 21 and a sealing part 22 arranged at one end of the supporting part 21, the anti-overflow valve 2 can move up and down to enable the sealing part 22 to seal or open the backflow port 13, the anti-overflow valve 2 further comprises a stop lip 23 extending outwards from the supporting part 21, the stop lip 23 extends obliquely along the direction opposite to the installation direction of the anti-overflow valve 2, and a gap 234 is formed between the stop lip 23 and the supporting part 21.

The spill valve 2 of the present utility model includes a support portion 21, a seal portion 22, and a stopper lip 23, and the seal portion 22 can be abutted against or separated from the cover 1 when the spill valve 2 is moved up and down to change its position, thereby blocking or conducting the return port 13. The stop lip 23 extends obliquely in the direction opposite to the mounting direction of the spill valve 2 and a gap 234 is formed between the stop lip 23 and the support part 21, so that the stop lip 23 is in an outward expansion umbrella shape, and the stop lip 23 and the sealing part 22 are positioned on the upper side and the lower side of the cover body 1, so that the spill valve 2 is limited from falling off the cover body 1.

When the spill valve 2 is installed, the spill valve 2 stretches into the installation opening 15 from one side of the cover body 1, and as the maximum outer diameter of the stop lip 23 is larger than the caliber of the installation opening 15, the stop lip 23 is extruded by the inner wall of the installation opening 15 and deforms inwards to be folded in the stretching process, so that the spill valve 2 can easily pass through the installation opening 15, and after the installation of the spill valve 2 is completed, the stop lip 23 is elastically expanded to form a stop with the cover body 1. When the anti-overflow valve 2 is pulled in the opposite direction, the stop lip 23 forms a stop with the cover body 1, and expands under the extrusion action of the cover body 1, so that the outer diameter of the stop lip 23 is further increased, and the stop lip 23 is more difficult to separate from the mounting opening 15, and because the stop lip 23 is of a structure made of elastic materials, after the stop lip is stopped with the cover body 1, the contact between the stop lip 23 and the cover body 1 is tighter and tighter along with the increase of the stop force, the friction resistance is gradually increased, and the separation of the stop lip from the mounting opening 15 is further effectively prevented, so that the problems that the anti-overflow valve 2 is easy to separate from the cover body 1 and difficult to assemble in production when being pulled by external force are effectively solved.

As shown in fig. 2 and 3, taking an example of the assembly mode that the cover 1 is provided with the mounting opening 15, the spill valve 2 passes through the mounting opening 15 from bottom to top, the stop lip 23 extends obliquely downwards, so that when the spill valve 2 is mounted relative to the cover 1 in an upward movement, the opening of the mounting opening 15 forms a downward extrusion force on the stop lip 23, and the extrusion force is approximately the same as the extending direction of the stop lip 23 (facing downwards), so that the stop lip 23 is folded towards the supporting part 21, the outer diameter of the stop lip 23 is reduced, and then the spill valve can easily pass through the mounting opening 15, and after passing through the mounting opening 15, the stop lip 23 loses a stop to rebound and returns to be expanded outwards to stop with the cover 1. When the spill valve 2 is pulled downward, the stopper lip 23 abuts against the upper end surface of the lid body 1, and the force of the lid body 1 to the stopper lip 23 is directed upward, opposite to the extending direction of the stopper lip 23, so that the stopper lip 23 is pressed to expand outward, and the spill valve 2 is prevented from sliding out of the mounting opening 15.

As a preferred embodiment of the present utility model, as shown in fig. 3, the stopping lip 23 has a fixed end 231 fixedly connected to the supporting portion 21, and a free end 232, the free end 232 being swingable around the fixed end 231 to allow the stopping lip 23 to expand in a direction away from the supporting portion 21 and to collapse in a direction toward the supporting portion 21.

The stop lip 23 is a swing arm structure with one end fixed and the other end free, so that the free end 232 can swing around the fixed end 231 more easily to deform, thereby enabling the stop lip 23 to have a folded state and an expanded state. The anti-overflow valve is easier to fold in the installation process to penetrate through the installation opening 15, the assembly difficulty is reduced, and the stop lip 23 can be easily expanded and deformed when being pulled in the opposite direction, and stops with the cover body 1 to limit the anti-overflow valve 2 from falling off.

Further, as shown in fig. 3, the free end 232 is provided with a support section 233 extending in the vertical direction, and the support section 233 can abut against the cover 1.

The support section 233 extends vertically, so that the hardness of the stop lip 23 can be increased, and further, after abutting against the cover 1, the stability of the stop lip 23 can be increased, so that it is kept in an umbrella-like structure. The stop lip 23 is prevented from being folded upwards and folded reversely when the spill valve 2 is pulled in a direction opposite to the installation direction, even though the spill valve 2 does not collapse the stop lip 23 under the action of its own weight. The presence of the support segment 233 helps to maintain the attitude of the stop lip 23 so that it does not fold in the direction opposite to the direction of extension itself when deformed by compression.

It should be noted that the present utility model is not limited to the structure of the stop lip 23, and in one embodiment, as shown in fig. 3, the stop lip 23 surrounds the outer periphery of the support portion 21. In another embodiment, the stop lips 23 are circumferentially spaced along the support 21 to save material and reduce cost while ensuring a release-preventing effect.

Preferably, as shown in fig. 3 and 5, the cover 1 is further provided with a mounting opening 15, the backflow opening 13 surrounds the outer periphery of the mounting opening 15, the support portion 21 passes through the mounting opening 15, and the projection of the sealing portion 22 toward the cover 1 covers the backflow opening 13.

Specifically, as shown in fig. 3, the supporting portion 21 extends into the mounting opening 15, the diameter of the sealing portion 22 is larger than the caliber of the mounting opening 15, so as to limit the floating amount of the anti-overflow valve 2, and meanwhile, the projection of the sealing portion 22 can cover the backflow opening 13, so that when the anti-overflow valve 2 floats upwards, the sealing portion 22 can seal the backflow opening 13 after abutting against the cover body 1.

The backflow port 13 may be an elongated port extending in an arc shape around the outer periphery of the mounting port 15, or may be circular holes arranged at intervals along the circumferential direction of the mounting port 15, which is not particularly limited herein.

Further, as shown in fig. 1 and 2, the cover body 1 includes a liner cover 11 and an inner cover 12, the inner cover 12 and the pot body enclose a cooking cavity, the mounting opening 15 and the return opening 13 are both opened on the inner cover 12, and the stop lips 23 and the sealing portion 22 are respectively located on the upper and lower sides of the inner cover 12.
