Further, as shown in fig. 5, fig. 5 is a schematic sectional view illustrating the movement of the upward pressure protection member in the pot lid of fig. 3 to the limit latch member. The pot cover 100 further includes an upper pressure protection member 60, the upper pressure protection member 60 is movably disposed on the cover body 10, and the upper pressure protection member 60 is used for limiting the telescopic movement of the locking pin member 30 under the action of the pressure in the pot body. In this embodiment, when pressure exists in the cooker body, the upper pressure protection member 60 limits the telescopic movement of the locking pin member 30 under the action of pressure in the cooker body, so that the cover 100 can be prevented from being opened by a user due to misoperation when pressure exists in the cooker body, and the safety performance of the cooking cooker can be improved.

In one embodiment, as shown in fig. 1 and 5, the cover 10 has a mounting hole 18, the locking pin 30 has a locking hole 36, a first portion of the upper pressure protection member 60 is inserted into the locking hole 36, a second portion of the upper pressure protection member 60 is inserted into the mounting hole 18 and hung on the cover 10, and the second portion of the upper pressure protection member 60 rises to the locking hole 36 under the action of the pressure in the pot body, so as to limit the telescopic movement of the locking pin 30.

Specifically, when there is no pressure in the pot, the upper pressure protection member 60 is hung on the lid 10, and the locking pin member 30 can move relative to the lid 10 under the driving of the linkage mechanism 40. When pressure exists in the pot body, the upper pressure protection piece 60 moves upwards under the action of the pressure in the pot body, so that the second part is inserted into the locking hole 36, when a user lifts the handle 20, the locking pin piece 30 tends to contract inwards, the second part of the upper pressure protection piece 60 can abut against the locking pin piece 30, the locking pin piece 30 is limited to contract to perform unlocking operation, and the safety performance of a product is further improved.

Further, the allowance of play between the outer wall of the first portion of the press-up protector 60 and the inner wall of the locking hole 36 is larger than or equal to the maximum displacement amount of the lock pin member 30, and the allowance of play between the outer wall of the second portion of the press-up protector 60 and the inner wall of the locking hole 36 is set smaller than the displacement amount required for unlocking the lock pin member 30.

Specifically, the allowance of play between the outer wall of the first portion of the push-up protector 60 and the inner wall of the locking hole 36 refers to: the locking pin member 30 can move a maximum distance relative to the push-up protector 60 when the first portion of the push-up protector 60 is disposed through the locking hole 36. The maximum displacement of the locking pin member 30 is referred to as: the maximum travel of the latch member 30 by the linkage 40. By setting the maximum distance that the lock pin member 30 moves relative to the upward pressing protection member 60 to be greater than or equal to the maximum displacement of the lock pin member 30, the interference of the upward pressing protection member 60 hung on the cover 10 on the lock pin member 30 can be avoided in the moving process of the lock pin member 30.

The allowance of play between the outer wall of the second portion of the push-up protector 60 and the inner wall of the locking hole 36 means: the locking pin member 30 can move a maximum distance relative to the push-up protector 60 when the second portion of the push-up protector 60 is disposed through the locking hole 36. The amount of displacement required to unlock the latch member 30 refers to: the distance between the position of the locking pin member 30 when locked relative to the pot body and the position of the locking pin member 30 when just unlocked relative to the pot body. By setting the allowance for movement between the outer wall of the second portion of the push-up protector 60 and the inner wall of the locking hole 36 to be less than the amount of displacement required for unlocking the locking pin 30, it is possible to prevent the locking pin 30 from unlocking relative to the pot body when the second portion of the push-up protector 60 is inserted into the locking hole 36.
