Specifically, for example, as shown in fig. 15, when the transmission member 411 moves in the x1 direction in response to the operation of the first operation member 200, the two locking members 300 are linked to move in the x21 direction and the x22 direction respectively, so that the locking members 300 move to both sides to release the cooking pot 30 for unlocking.

And wherein, through setting up driving medium 411 in lid 100, can do benefit to the operating stability who guarantees driving medium 411, wherein, driving medium 411 cooperates with closure 300, and closure or unblock are carried out through driving medium 411 motion linkage closure 300, can utilize the stability of driving medium 411 to strengthen the motion stability of closure 300 like this, promote the closure precision of closure 300 and cooking pot 30 to promote the pressure-bearing reliability of cooking equipment 1, improve the security level of cooking equipment 1.

Further, the engaging member 420 is adapted to engage with the driving member 411 and to restrain or release the driving member 411. Like this, based on driving member 411 motion with linkage closure 300 lock or unblock, through design fitting piece 420 adaptation driving member 411, like this, fitting piece 420 can be through controlling the motion of driving member 411 to correspondingly control the action of closure 300, and also more steady, accurate to the control of closure 300.

Further, as shown in fig. 16, the number of the fitting members 420 is plural, the plural fitting members 420 are located at one side of the transmission member 411 and are respectively fitted with the transmission member 411, and at least two fitting members 420 are distributed at two end positions of one side of the transmission member 411 (specifically, for example, two fitting members 420 are distributed at the front side of the transmission member 411 and are located at the left and right end positions of the front side of the transmission member 411 as illustrated in fig. 16). Like this, more do benefit to the atress of driving medium 411 even, make driving medium 411 be difficult to the skew, like this, the motion of driving medium 411 can be more steady, accurate, so both makes the closure of control closure 300 or unblock more steady, smooth and easy, also makes the cooperation switch between mating part 420 and the driving medium 411 more accurate to promote the lid and close auto-lock response precision.

Of course, the present solution is not limited to this, and in other embodiments, the fitting member 420 may be located on one side of the transmission member 411 and distributed at a middle position of one side of the transmission member 411 (for example, located at the left and right ends of the front side of the transmission member 411).

In certain embodiments, as shown in fig. 8 and 10, transmission piece 411 is provided with an adaptation portion 4111. More specifically, the adapting portion 4111 may be specifically, for example, a flange protruding forward from the transmission member 411.

As shown in fig. 19, the lid opening button includes a button securing plate 510 (i.e., the snap member 500) and a button assembly (i.e., the second operating member 40). The upper cover assembly is buckled with the cooker body assembly (i.e. the base body 20) through the button buckle plate 510 (i.e. the buckling member 500).

As shown in fig. 19, the housing cover 21 of the pot body assembly has at least one boss (i.e., the trigger part 22) near the button fastening plate 510 (i.e., the fastening part 500), and more specifically, the housing cover 21 of the pot body assembly is provided with two button fastening plates 510 (i.e., the fastening parts 500) and two bosses (i.e., the trigger part 22).

The unlocking button (i.e., the first operating member 200) specifically includes a button and a push rod, wherein the push rod of the unlocking button (i.e., the first operating member 200) is disposed at one end of the transmission member 411 for moving the transmission member 411. The other end of the transmission member 411 is provided with a driving spring (i.e., a third elastic member 412), and the driving spring (i.e., the third elastic member 412) is used for resetting the transmission member 411.

As shown in fig. 21 and 22, the locking element 300 of the covering self-locking mechanism 400 includes a metal locking buckle (i.e., the locking buckle 302) and a sliding block 301, the upper cover assembly specifically includes the inner cover 110, the cover plate 120, and the like, and the inner cover 110 is provided with a limiting block (i.e., the engaging element 420) and a return spring (i.e., the second elastic element 430). The stopper (i.e., the engaging member 420) is provided with an engaging groove 421 and a stopper (i.e., a portion around the engaging groove 421).

When the upper cover assembly is closed, the stop block (i.e., the engaging member 420) contacts with the boss disposed on the housing cover 21, and the stop block (i.e., the engaging member 420) compresses the return spring (i.e., the second elastic member 430) to move upward along with the closing action. After the limiting block (also, the matching piece 420) moves a certain position, the limiting block (also, the matching piece 420) loses the limiting effect on the transmission piece 411, for example, the matching groove 421 corresponds to the position of the adapting portion 4111 of the transmission piece 411, and the matching groove 421 forms an avoiding effect on the adapting portion 4111, so that the limiting effect of the matching piece 420 on the transmission piece 411 is lost. At this time, as shown in fig. 21, the driving spring (i.e., the third elastic member 412) moves the driving member 411 in the direction x1 shown in fig. 21, and the sliding groove 4112 disposed on the driving member 411 drives the sliding block 301 to move towards the center of the cooking pan 30 by a predetermined distance (i.e., the locking member 300 moves in the direction x21 and the direction x22 shown in fig. 21) by cooperating with the sliding portion 310, so that the locking portion 520 of the metal lock catch and the rim of the cooking pan 30 complete the locking. When the lid 10 finally completes the closing action, the button fastening plate 510 (i.e. the second fastening lug 700) of the inner lid 110 is fastened with the button fastening plate 510 (i.e. the fastener 500) of the outer shell 21.

As shown in fig. 22, when a user needs to open the lid, the unlocking button (i.e., the first operating element 200) is pressed first, the push rod of the unlocking button pushes the transmission element 411 to move forward (i.e., the transmission element 411 moves in the direction x1 shown in fig. 22), the sliding slot 4112 arranged on the transmission element 411 moves the slider 301 a set distance in a direction away from the center of the inner lid 110 (i.e., the locking element 300 moves a set distance in the directions x21 and x22 shown in fig. 22) by cooperating with the sliding portion 310, and finally the engaging portion 520 of the metal lock catch is separated from the rim of the cooking pot 30, the limiting block (i.e., the engaging element 420) is reset by the reset spring (i.e., the second resilient element 430), and the stopping portion arranged on the limiting block (i.e., the engaging element 420) and the protruding portion (i.e., the adapting portion 4111). At this time, the user presses the switch button (i.e., the second operating member 40) to complete the opening of the cover.

It can be understood that, in the pressure-bearing structure of the pressure rice cooker in the related art, a metal bridge is mostly arranged on the cooker cover 10 and the base 20, and the metal bridge generally consists of two longitudinally distributed metal pieces and at least one transversely distributed metal piece, so that the problems of complex parts, low assembly efficiency and the like of the base 20 exist.

In the scheme, the cooking pot 30 is buckled by the lock catch 302 of the locking piece 300, so that the metal pressure-bearing structure is improved, and the bridge structure can be eliminated. More specifically, for example, the cover plate 120 (preferably made of metal) and the rim (also referred to as rim 31) of the cooking pan 30 are fastened together by using more than two fasteners 302 (preferably made of metal) to form a pressure-bearing structure. In addition, the boss, the matching piece 420 and the cover closing self-locking mechanism 400 are linked in the scheme, so that the effect that the lock catch 302 is automatically buckled when the cover is closed can be realized. The control fitting piece 420 is matched with the transmission piece 411 through the fitting groove 421 or the stopping portion, so that locking or unlocking is controlled, the number of parts designed by the whole linkage mechanism is small, the number of response stages of linkage or transmission is small, control precision and reliability are improved, the problem that the electric cooker cannot normally open or close the cover due to aging or deformation of parts is solved, and the reliability of the function of opening or closing the cover of the product is improved.
