When the locking cover 21 rotates to the first set position, the elastic device does not deform, when the locking cover 21 continues to rotate to the second set position, the elastic device deforms, and after the pot cover 2 is opened, the elastic device recovers to deform to drive the locking cover 21 to rotate. That is, the locking cover 21 does not interact with the elastic means when rotating from the locking position to the first setting position, and deforms the elastic means when rotating from the first setting position to the second setting position. After the pot cover is opened, the force of the cover opening component is released, so the elastic device drives the locking cover 21 to rotate, and the locking cover 21 acts on the elastic device after rotating to the first set position, so the elastic device recovers the deformation to react with the locking cover to make the rotating angle beta of the locking cover smaller than alpha. Because the unlocking piece 212 is arranged on the locking cover 21, the movable clamping piece is unlocked through the rotation of the locking cover 21, the locking cover 21 can be driven to rotate when the movable clamping piece returns after being unlocked, and the rotation angle beta of the locking cover is smaller than alpha, so that teeth on the locking cover can not collide with teeth on the pot body when the locking cover is closed again. Optimally, alpha is half of beta, for example, alpha is 6 degrees, beta is 3 degrees, so that the lock cover can be collided with teeth after rotating for 3 degrees and the allowance of 3 degrees is left, and the situation that the teeth are collided when errors occur in the manufacturing process is avoided. Specifically, the elastic device comprises a first elastic device 8 acting on the movable clamping piece 3, when the shifting fork piece 4 drives the locking cover 21 to rotate to a second set position, the tripping piece 212 triggers the rotary transmission piece 5 to rotate, the first elastic device 8 deforms when the rotary transmission piece 5 triggers the movable clamping piece 3, and the movable clamping piece 3 and the fastener 11 are separated to open the pot cover 2; when the pot cover 2 is opened, the first elastic device 8 recovers deformation to drive the rotary transmission member 5 to rotate. The rotation transmission member 5 is rotated to act on the release member 212, thereby driving the locking lid 21 to rotate. The first elastic means 8 may be a spring or a torsion spring or the like. Because be equipped with first resilient means 8 on activity fastener 3, can ensure to close lid lock next time in the return of activity fastener 3 after uncapping, moreover, can realize the gyration of rotating-driving spare 5.

The second elastic means 9 is a spring. One end of the spring is fixed with the rotating transmission piece 5, and the other end is fixed on the lining 22. Because the inner liner 22 is always fixed, the rotating transmission member 5 can move relative to the inner liner 22, when the rotating transmission member 5 is triggered by the releasing member 212 to move relative to the inner liner 22, the spring is deformed, specifically, the deformation can be compression or stretching or bending, and the like, and after the pot lid 2 is opened, the force applied to the releasing member 212 is released, the second elastic device 9 recovers the deformation to drive the rotating transmission member 5 to rotate. The rotation of the rotating transmission member 5 also drives the release member 212 to rotate, thereby rotating the locking cover 21. Because the second elastic device 9 is also arranged on the rotating transmission member 5, the rotation of the rotating transmission member 5 is further realized after the cover is opened. Because the gyration of the rotating transmission member 5 can be realized by the first elastic device 8, after the second elastic device 9 is arranged, the gyration of the rotating transmission member 5 can be realized by the first elastic device 8 under the combined action of the first elastic device and the second elastic device, and then the gyration of the release member 212 is realized, and the locking cover 21 is further made to gyrate. If only realize the gyration of rotating-driving spare 5 through first resilient means 8, need first resilient means 8 to take place great deformation, produce great resilience force, and this can influence the feeling when 2 buckles of pot cover, through increasing second resilient means 9, can share the resilience force of the required production of first resilient means 8, ensure that 2 buckles of pot cover feel good. In other embodiments, the elastic means may also comprise third elastic means acting on the fork 4 and even fourth elastic means acting on the rotation knob 6. Because the shifting fork piece, the rotating handle, the rotating transmission piece, the movable clamping piece and the like are all linked with the locking cover, after the pot cover 2 is opened, the elastic device is arranged to drive the locking cover 21 to rotate under the action of the elastic device.
In this embodiment, the lock cover 21 is provided with a lock cover column 21, the lining 22 is provided with an avoiding groove, the avoiding groove comprises a first avoiding groove 221 and a second avoiding groove 222, and the release member 212 passes through the first avoiding groove 221 and extends to the upper surface of the lining 22, so as to act on the movable clamping member 3.

The first avoiding groove 221 is closer to the center of the locking cover 21 and is spaced 3-9 cm away from the center of the locking cover 21, i.e. the distance between the release member 212 and the center of the locking cover 21 is 3-9 cm. Preferably, the avoiding grooves are arc-shaped avoiding grooves, and the corresponding angle of the arc-shaped avoiding grooves is 25-35 degrees. Because the angle that the locking closure 21 rotated in the lid process of opening and shutting is about 30, corresponding locking closure post 211 and release piece 212 are owing to extend to inside lining 22 upper surface, and its orbit also forms an arc about 30 and dodges the groove, so, the best, dodge the groove and also dodge the groove for the arc about 30, can avoid inside lining 22 to set up and dodge the intensity behind the groove and weaken too much like this. The distance d between the release member 212 and the center of the locking cover 21 is 3-9 cm, so that the stroke of the movable clamping member under the action of the release member 212 can be reduced. Or, the distance between the release member 212 and the center of the locking cover 21 is 1/5-4/5 of the radius of the locking cover 21, specifically, the radius r of the locking cover 21 is about 13 cm, the rotation angle of the locking cover 21 is constant, the rotation stroke (arc length) of the release member 212 is the rotation angle of the locking cover 21 multiplied by the distance between the release member 212 and the center of the locking cover, on the premise that the rotation angle is constant, when the release member 212 is close to the center of the locking cover 21, the rotation stroke of the release member 212 is small, and in order to ensure that the rotation stroke of the release member 212 is moderate, the distance d between the release member 212 and the center of the locking cover 21 is preferably 3-9 cm. When d is less than 3 cm, the rotation stroke of the release piece 212 is too small, the action distance of the action piece 3 is too short, so that the action piece 3 is difficult to be acted and separated from the fastener 11, when d is more than 9 cm, the rotation stroke of the release piece 212 is too large, the action distance of the action piece 3 is too long, so that the action piece 3 is acted by the release piece 212 in a long stroke, the stroke of the action piece 3 separated from the fastener 11 is limited, and the stroke can be mismatched with the release stroke. Because the tripping part 212 has a certain distance with the movable clamping part 3, a rotary transmission part 5 is arranged between the two parts, and the action distance of the movable clamping part 3 can be adjusted by adjusting the rotation center of the rotary transmission part 5 to match with the tripping stroke of the movable clamping part 3.
In this embodiment, the locking cover 21 is a steel cover, the pot body 1 includes an inner container 12, and the locking cover 21 and the inner container 12 are sealed to form a cooking cavity.

The specific working principle is as follows: in an initial cover closing and locking state, as shown in fig. 3, cover teeth of the cover 2 are engaged with pot teeth of the pot body 1, and the cover 2 is buckled with the pot body 1 through a buckle piece. The closed cover locking state can perform pressure cooking work. When the cooker cover 2 needs to be opened, the rotating handle 6 is rotated, the rotating handle 6 drives the shifting fork piece 4 to rotate, and the shifting fork piece 4 drives the locking cover 21 to rotate. When the shifting fork 4 drives the locking cover 21 to rotate to the first set position, as shown in fig. 4, the cover teeth are staggered with the pot teeth, the locking cover 21 is in an unlocking state, and the unlocking member 212 is about to act on the rotating transmission member 5. When the locking cover 21 continues to rotate to the second setting position, as shown in fig. 5, the cover teeth and the pot teeth are still staggered, the locking cover 21 is still in the unlocking state, and in the process, the release member 212 triggers the rotating transmission member 5, the rotating transmission member 5 triggers the movable clamping member 3, the movable clamping member 3 is separated from the fastener 11 on the pot body 1, and the pot cover 2 springs open to be separated from the pot body 1. While the rotary actuator 5 is activated, both the first elastic means 8 and the second elastic means 9 are deformed. In the cover opening process, the acting force is applied to the rotating handle 6, the rotating handle 6 drives the shifting fork piece 4 to drive the locking cover 21 to reach the second set position, the releasing piece 212 on the locking cover 21 also triggers the movable clamping piece 3 through the rotating transmission piece 5 to separate the pot cover 2 from the pot body 1, after the pot cover 2 is separated from the pot body 1, the external acting force on the rotating handle 6 disappears, after the acting force on the rotating handle 6 disappears, the shifting fork piece 4 does not receive the acting force of the rotating handle 6 any more, the locking cover 21 does not receive the acting force any more, so that the first elastic device 8 and the second elastic device 9 both recover deformation, the rotating transmission piece 5 rotates, the rotating transmission piece 5 drives the releasing piece 212 to further rotate the locking cover 21, as shown in fig. 6. While the locking cover 21 rotates, the movable clamping piece 3 also returns to the initial state, namely, the position which can act with the clamping piece 11 on the pot body 1. When the cooker cover 2 needs to be closed again, the cooker cover 2 is buckled, the movable clamping piece 3 is meshed with the buckling piece 11 on the cooker body 1 to enable the cooker cover 2 to be buckled, then the rotating handle 6 is rotated to realize the locking of the cover teeth and the cooker teeth, and the original cover closing and locking state is returned. The cover opening process can also be seen, the electric pressure cooker of the embodiment realizes the process of opening the cover only through one rotation action, the operation is simple, and the cover opening is convenient.
Because the movable clamping piece 3 is positioned at the edge of the upper surface of the lining 22, and the locking cover 21 is positioned below the lining 22, the inner lining 22 is creatively provided with the avoiding groove in the embodiment, the unlocking piece 212 is arranged on the locking cover 21, and the unlocking piece passes through the avoiding groove and extends to the upper surface of the lining 22 to be linked with the movable clamping piece 3, so that the aim of opening the cover by rotating the locking cover 21 to act on the movable clamping piece 3 is fulfilled.

The present embodiment matches the trip travel of the movable catch 3 by providing an escape groove in the middle region of the liner 22 and a transmission between the trip member 212 and the movable catch 3. In addition, in the actual manufacturing process, the cover opening is accurately released by adjusting the transmission piece according to the deviation in the cover opening releasing process, so that the rotation angle is matched with the opening releasing stroke, and the adjusting mode is simple and feasible due to the structure.
The unlocking piece is arranged on the lock cover, and the movable clamping piece is triggered by the unlocking piece to open the lock cover in the rotating process of the lock cover. Because the unblock of locking closure must need rotatory, makes the activity fastener uncap with the help of the rotation of locking closure, need not set up in addition rotary part on other parts of pot cover and act on the activity fastener, simple structure practices thrift the cost. Because the movable clamping piece needs to return to ensure the next fastening after the pot cover is opened, and the rotation of the locking cover can realize the unlocking and locking with the pot body, generally speaking, after the pot cover is opened, in order to ensure the pot cover can be fastened again, the movable clamping piece needs to return, if the locking cover rotates, the cover teeth on the locking cover and the pot teeth on the pot body can collide with each other, so the locking cover cannot rotate, and generally, the movable clamping piece can not be acted by directly arranging the unlocking piece on the locking cover. And because the locking cover is positioned below the lining, the movable clamping piece is arranged on the lining, and the rotation of the locking cover can not act on the movable clamping piece. The tripping piece extends to the upper surface of the lining and then acts with the movable clamping piece, horizontal acting force is applied to the transmission piece in the rotating and unlocking process, the transmission piece returns and applies force to the tripping piece after the cover is opened, so that no friction and other losses exist in the acting force between the transmission piece and the tripping piece, the force transmission efficiency is high, the locking cover can be ensured to rotate due to the fact that the acting force required by the rotation of the locking cover is large and the acting force loss is small, and therefore the movable clamping piece can return, and the pot cover can be buckled after the cover is opened.
