Description
Technical Field
The invention relates to the field of kitchen appliances, in particular to a cover opening device of an electric pressure cooker and the electric pressure cooker.
Background
Under the general condition, the cover opening of the electric pressure cooker needs two steps, the lock catch is rotated firstly and then the cover opening button is pressed, and when the lock catch does not rotate in place, the cover opening button is pressed, so that the cover opening purpose cannot be achieved, and the protection is formed for a user.
The aim of preventing the false cover opening is achieved through the cooperation of the lock catch and the cover opening button in the existing electric pressure cooker, specifically, a notch is formed in the lock catch, after the cover is closed, the lock catch rotates, the position with the notch rotates to leave the cover opening button, the moving position of the cover opening button cannot move due to the fact that the position is blocked by the lock catch, and finally, the purpose of preventing the cover opening cannot be achieved; in the uncapping process, the lock catch rotates, the position of the lock catch with the notch rotates to the position of the uncapping button, at the moment, the uncapping button is not blocked by the lock catch any more, the uncapping button is pressed, and the uncapping button can move to realize uncapping. This mode is based on four parts of uncapping button, hasp, inner cup, shell cover, and the size that the size chain contained is many, and the relativity of size chain is big, and the size of shell cover is great, and the thickness of hasp is less with uncapping button stroke, and the stroke tolerance of control uncapping button is less, requires highly to the dimensional accuracy, is difficult to guarantee the stability of mechanism.

Specifically, the electric pressure cooker comprises a cooker body and a cover body covered on the cooker body, wherein the cover body comprises an inner cover 10 and a lock cover 20 (the lock cover can also be a cooker cover) arranged on the inner cover 10; the cover opening button 50 is installed on the outer cover 30 of the pot body and can be clamped with the inner cover 10 of the cover body; the linkage slide block 40 is rotatably installed on the inner cover 10, the linkage slide block 40 is provided with a first cantilever 41 and a second cantilever 42 which are connected, the first cantilever 41 can drive the lock cover 20 of the cover body to switch between a locking position and an unlocking position, and a handle or an electric driving unit (not shown in the figure) for driving the linkage slide block 40 to rotate is arranged on the inner cover 10; wherein, as shown in fig. 6 to 8, when the first cantilever 41 drives the locking cap 20 to move to the locking position, the second cantilever 42 interferes with the cap opening button 50 to prevent the cap opening button 50 from being moved to the cap opening position; as shown in fig. 3 to 5, when the first cantilever 41 drives the latch cover 20 to move to the unlock position, the second cantilever 42 is out of interference with the door button 50, so that the door button 50 can be moved to the door position.
According to the cover opening device of the electric pressure cooker, provided by the technical scheme, the handle or the electric driving unit arranged on the inner cover 10 is used for driving the linkage slide block 40 to rotate relative to the inner cover 10, namely, the rotation of the linkage slide block 40 can be realized manually or electrically, the linkage slide block 40 is provided with the first cantilever 41 and the second cantilever 42 which are connected, when the linkage slide block 40 rotates, the first cantilever 41 rotates together with the second cantilever 42, the first cantilever 41 has the function of poking the lock cover 20, and the second cantilever 42 has the function of interfering the cover opening button 50; specifically, as shown in fig. 3 to 5, during the process of opening the lid, the first cantilever 41 of the linkage slider 40 rotates by a certain angle to drive the lock cover 20 matched with the first cantilever 41 to rotate to an unlocking position (unlocking position, namely, a position where the cover teeth on the lock cover 20 can be separated from the pot teeth on the pot body), at this time, the second cantilever 42 also rotates by a certain angle along with the first cantilever 41, so that the second cantilever 42 and the lid opening button 50 are separated from each other (separation interference, namely, a track through which the second cantilever 42 moves to the lid opening position away from the lid opening button 50), at this time, the lid opening button 50 can be pushed, and thus the lid opening function is realized by pressing the lid opening button 50; as shown in fig. 6 to 8, in the process of closing the lid, the first cantilever 41 that slides in linkage rotates reversely by a certain angle to drive the lock lid 20 that cooperates with the first cantilever 41 to rotate to the locking position (locking position, i.e. the position where the lid teeth on the lock lid 20 are rotationally buckled with the pot teeth on the pot body), at this time, the second cantilever 42 also rotates reversely by a certain angle along with the first cantilever 41, so that the second cantilever 42 interferes with the lid opening button 50 (interference occurs, i.e. the second cantilever 42 is located on the track through which the lid opening button 50 moves to the lid opening position), at this time, the lid opening button 50 is pressed, and the lid opening button 50 cannot move because it is blocked by the second cantilever 42, thereby achieving the purpose of preventing the lid opening. According to the cover opening device of the electric pressure cooker, the first cantilever 41 of the linkage sliding block 40 plays a role in poking the lock cover 20, the second cantilever 42 of the linkage sliding block 40 plays a role in interfering the cover opening button 50, the size contained by the size chain is small, the relevance of the size chain is small, the requirement on the size precision is low, and the stability of the mechanism is easier to guarantee.
Of course, the above-described cover opening device of the electric pressure cooker is equally applicable to the case where the cover opening button 50 is provided on the cover body of the electric pressure cooker, and specifically, the cover opening button 50 is fixed to the inner cover 10 of the cover body, and the cover 30 of the cooker body is provided with a fastening position for fastening the cover opening button 50.
