[0034] A locking structure 4 is provided on the pot body 1 corresponding to the snap-fit ​​structure 3. The locking structure 4 can be snap-fitted with the snap-fit ​​structure 3. When the locking structure 4 moves toward the pot cover 2, the pot cover 2 can be locked on the pot body 1. By using the locking structure, the inner pot of the cooking utensil can be smoothly pressed up and the pressure can be stably maintained. By using another pressure relief device and program setting, the inner pot can be maintained within a set pressure range to achieve the micro-pressure cooking set by the cooking utensil. The sealed locking structure can effectively prevent gas leakage and ensure the stability of the pressure inside the cooking utensil to ensure that the food is fully cooked. The locking structure is reasonably designed and easy to operate. The user can easily lock the pot cover on the pot body without the need for additional force or tools. The utility model has a simple and reliable structure, is easy to operate, has a simple and elegant appearance, and is also conducive to reducing product costs.

[0035] Preferably, if Figure 2 As shown, the clamping structure 3 includes a first clamping member 31 arranged on the peripheral side of the pot cover 2 and extending to the outside of the pot cover 2, and a second clamping member 32 arranged on the lower side of the pot cover 2.

The pot body 1 is also provided with a guide groove 11. The locking structure 4 can reciprocate along the length direction of the guide groove 11 to lock or unlock the pot body 1. The design of the first clamping member 31 and the second clamping member 32 enables the pot cover to be locked in two directions, thereby enhancing the sealing and stability. The existence of the slide rail 10 enables the first clamping member 31 to slide on the pot body, so that the user can easily place the pot cover in the correct position when using it. The setting of the guide groove 11 allows the locking structure 4 to move along a specific path on the pot body. This design makes the operation of the locking structure smoother and more stable, enhances the functionality and operability of the locking structure, and further improves the user experience of the micro-pressure cooking appliance.

[0036] Preferably, if Figure 3 , 4 As shown, the locking structure 4 includes a locking member 41 with one end embedded in the guide groove 11 and abutting against the pot cover 2, a reset structure 42 provided on the guide groove 11 and sleeved on the lower side of the locking member 41, and a limiting member 43 provided on the lower side of the reset structure 42 for fixing the locking member 41. The locking member 41 can reciprocate along the length direction of the guide groove 11, and the reset structure 42 can reset the locking member 41 in the direction close to the pot cover 2. The safe locking of the pot cover can be ensured by setting the locking member, and the pot cover can be easily unlocked and locked by setting the reset structure, which is convenient for users to operate. The limiting member is used to limit the locking member in the handle to keep the pot cover stably locked.

[0037] Preferably, the reset structure 42 includes a clearance hole 421 provided on the pot body 1 for the locking member 41 to be inserted, and a reset member 422 provided in the clearance hole 421 for resetting the locking member 41. More preferably, the reset member is an elastic reset member, which may be a spring or a reset member made of elastic material.

[0038] Preferably, if Figure 6 As shown, the reset member 422 is in a Y-shaped forked structure, and the reset member 422 includes a fixed end 422a fixed to the side of the yield hole 421 close to the pot cover 2 and a forked end 422b extending in a direction away from the pot cover 2, and the middle part of the forked end 422b can be used for the locking member 41 to be inserted. By setting the reset member to a Y-shaped forked structure, the locking member can be inserted in the middle part of the forked end for easy reset, and the forked end is the main reset part, which can effectively save materials and the difficulty of assembly, thereby reducing the production cost of the enterprise.

[0039] Preferably, if Figure 6 , 7 As shown, the locking member 41 includes a button portion 411 that can cooperate with the guide groove 11, an abutment portion 412 provided at one end of the button portion 411 close to the pot cover 2, and an insertion portion 413 provided at the lower side of the button portion 411, the insertion portion 413 can be inserted into the reset structure 42 and fixedly connected to the limit member 43, the button portion 411 can cooperate with the guide groove 11, so that the locking member 41 can be accurately locked in the desired position, ensuring the sealing and stability between the pot cover 2 and the pot body 1, the insertion portion 413 is located on the lower side of the button portion 411, can be inserted into the reset structure 42, and fixedly connected to the limit member 43, so that the structure of the locking member is more compact, the possibility of loosening or falling off is reduced, and the reliability and durability of the locking member are improved.

[0040] Preferably, if Figure 6As shown, a notch 4121 is provided on the abutment portion 412 corresponding to the slide rail 10 and is recessed in a direction away from the pot cover 2. The notch 4121 can be connected to the slide rail 10 and can limit the first clamping member 31 in the slide rail 10. By setting the notch, when the pot cover is placed on the pot body, the first clamping member moves along the guide rail as the pot cover rotates. When it moves to the end of the guide rail, the first clamping member is reset to a locked state. When the pot cover is unlocked, the first clamping member pushes the locking member out along the guide groove through the notch to open the pot cover.

[0041] Preferably, if Figure 2 , 3 As shown in FIG. 4 , the first clamping member 31 and the second clamping member 32 are each provided with two groups, and the two first clamping members 31 are symmetrically arranged. The first clamping member 31 and the second clamping member 32 are spaced apart on the pot cover 2. By arranging two groups of the first clamping member 31 and the second clamping member 32 and symmetrically arranging them, the supporting points of the pot cover 2 can be increased, the pressure can be dispersed, and the stability and balance of the pot cover can be improved. The spaced-apart first clamping member 31 and the second clamping member 32 can effectively fix the pot cover 2 to prevent accidents caused by failure of a single supporting point, thereby improving the safety and stability of the cookware. The arrangement of the two groups of clamping members can evenly distribute the weight and pressure of the pot cover 2, reduce the load on a single supporting point, improve the bearing capacity of the pot cover, and extend its service life.

[0042] Preferably, if Figure 2 As shown, a card slot 12 is also provided on the circumferential side of the pot body 1 corresponding to the second card connector 32, and the second card connector 32 can be engaged with the card slot 12 in cooperation with each other. The engagement between the card slot 12 and the second card connector 32 can effectively fix the pot cover 2 to prevent accidental falling off or loosening, thereby improving the safety of the pot and ensuring stability and safety during the cooking process.

[0043] Preferably, if Figure 1 , 2 As shown, a handle 5 is further extended outwardly on the periphery of the pot body 1, and the guide groove 11 is recessed on the handle 5. The locking structure 4 is cooperatively connected with the guide groove 11. By arranging the handle 5 on the periphery of the pot body 1, the user can more conveniently lift and move the entire pot, thereby improving the convenience of carrying and operation. By arranging the locking structure on the handle, the overall simplicity and beauty are maintained, the structure is simple, and it is easy to use, and the connection stability between the pot body 1 and the pot cover 2 is increased, thereby preventing loosening or falling off during carrying or use.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
