Referring to fig. 1 and 2, the pressure cooker provided by an embodiment of the utility model comprises a cooker cover 100 and a cooker body 110, wherein the cooker cover 100 comprises an inner cover 10, a heat-insulating cover plate 11 and a cooker tooth ring 20, and the cooker tooth ring 20 is movably mounted on the inner cover 10 and can be buckled with or separated from the cooker body 110 to realize closing and locking or separation of the cooker cover 100 and the cooker body 110.

The heat-insulating cover plate 11 is detachably mounted on the inner cover 10, so that the heat-insulating cover plate 11 is conveniently cleaned, and in order to avoid a series of problems caused by pressure cooker caused by neglecting to mount the heat-insulating cover plate 11, the cooker cover 100 further comprises a cover opening buckle 30 movably mounted on the inner cover 10, the cover opening buckle 30 comprises a locking part 31, the cooker tooth ring 20 comprises a matching part 21, and the locking part 31 can be mutually locked or separated from the matching part 21.

Specifically, when the user neglects to install the heat-insulating cover plate 11, that is, when the heat-insulating cover plate 11 and the inner cover 10 are separated from each other, referring to fig. 3, 4 and 5, the locking portion 31 and the matching portion 21 are locked with each other, so that the pan rim 20, the cover opening buckle 30 and the inner cover 10 form a whole, the pan rim 20 cannot generate relative movement with respect to the inner cover 10, and cannot be buckled with the pan body 110, and the pan cover 100 cannot be closed and locked with the pan body 110. Thus, the user finds that the cover 100 and the cooker body 110 cannot be closed and locked in the using process, and the pressure cooker cannot be started normally, so that the user is reminded of missing the fitting of the pressure cooker, and the safety of the pressure cooker in the using process is greatly improved.

When the user normally installs the heat-insulating cover plate 11, the heat-insulating cover plate 11 and the inner cover 10 are normally assembled, referring to fig. 1 and 2, the locking portion 31 and the matching portion 21 are separated from each other, the pan rim 20 is convenient for the cover opening buckle 30 to be separated from each other, so that the pan rim 20 can normally move relative to the inner cover 10 to be buckled with the pan body 110, the pan cover 100 can be normally closed and locked with the pan body 110, and the pressure cooker can be normally started.

Above-mentioned pot cover, after the user normally installs heat preservation apron 11, locking part 31 and cooperation portion 21 separation each other, pot rim 20 can normally with the mutual lock of pot body 110, the pressure cooker just can normally start yet. When the user neglects to install the heat-insulating cover plate 11, the locking part 31 of the cover opening buckle 30 and the matching part 21 of the pan tooth ring 20 are mutually locked, so that the pan tooth ring 20 cannot be mutually buckled with the pan body 110, the pan cover 100 and the pan body 110 cannot be closed and locked, and the pressure cooker cannot be normally started to remind the user of neglecting to install accessories of the pressure cooker, and the safety of the pressure cooker in the use process is greatly improved.

In the embodiment of the utility model, the cover opening buckle 30 comprises a card body 34, the locking part 31 is convexly arranged at one side of the card body 34 facing the pan ring 20, the card body 34 can reciprocate relative to the inner cover 10 under the action of external force, and the card body 34 can drive the locking part 31 to be combined with or separated from the matching part 21 in the moving process, so that the locking or separation of the locking part 31 and the matching part 21 can be controlled by controlling the reciprocation of the card body 34.

Specifically, the card body 34 includes a first position and a second position during movement relative to the inner cover 10, and the locking portion 31 is locked with the mating portion 21 when the card body 34 is in the first position; when the card body 34 is in the second position, the locking portion 31 is separated from the engaging portion 21. After the inner cover 10 and the heat-preserving cover 11 are assembled with each other, the heat-preserving cover 11 can directly or indirectly drive the card body 34 to move, so that the card body 34 can move to the second position, i.e. the locking portion 31 and the matching portion 21 are separated from each other, the pan tooth ring 20 can be normally buckled with the pan body 110, and the pressure cooker can be normally started.

When the heat-insulating cover 11 and the inner cover 10 are separated from each other, the heat-insulating cover 11 cannot keep the card body 34 at the second position, and the card body 34 is reset to the first position, so as to drive the locking portion 31 and the matching portion 21 to lock with each other. Thus, by resetting the clamp body 34, when the thermal insulation cover plate 11 is neglected to be installed, the locking part 31 is mutually locked with the matching part 21, so that the pot cover 100 and the pot body 110 cannot be closed and locked, and the neglected installation of the pressure cooker is realized.

It should be noted that, the reciprocating movement of the card body 34 may be completed by adopting a pneumatic stay, an elastic member 12 described below, and other reset components, or by adjusting the weight of the card body 34 itself, so that the weights of the two ends of the card body 34 are inconsistent, and when the thermal insulation cover 11 and the inner cover 10 are separated from each other, the card body 34 will rotate towards the heavy end by itself under the action of gravity, thereby realizing the self-reset of the card body 34.

In some embodiments, the lid 100 further includes an elastic member 12, where the elastic member 12 is connected to the card body 34 and the inner lid 10, respectively, so that the card body 34 can reciprocate relative to the inner lid 10 by elastic deformation of the elastic member 12. Specifically, when the inner lid 10 and the insulating cover 11 are assembled with each other, the elastic member 12 is compressed or stretched between the lid opening and the inner lid 10, that is, when the insulating cover 11 is in the second position, the elastic member 12 can provide an elastic force for moving the insulating cover 11 toward the first position. When the inner cover 10 and the thermal insulation cover 11 are separated from each other, the thermal insulation cover 11 cannot continuously support the card body 34 to be in the second position, and then the elastic member 12 recovers the deformation and drives the card body 34 to move to the first position, so as to complete the self-resetting of the card body 34.

Alternatively, the elastic member 12 is a spring, and two ends of the spring are respectively connected to the elastic buckle 35 and the inner cover 10, so that the card body 34 stretches or compresses the spring during the movement relative to the inner cover 10, so as to push the card body 34 to move from the second position to the first position through the restoring deformation of the spring.

In particular, in the embodiment, the card body 34 is rotatably mounted on the upper inner cover 10, one end of the card body 34 is connected to the elastic member 12, and the other end is used for abutting against the heat insulation cover 11. In the process of mounting the heat insulation cover plate 11 on the inner cover 10, the heat insulation cover plate 11 is first abutted against the card body 34, and then the heat insulation cover plate 11 is fixed on the inner cover 10 by the clamping or fastening piece, and the heat insulation cover plate 11 simultaneously drives one end of the card body 34 to rotate, so that the card body 34 rotates from the first position to the second position. The other end of the card body 34 rotates simultaneously with the one end, so that the end of the card body 34 provided with the elastic member 12 rotates along with the one end, and the elastic member 12 is stretched or compressed by the card body 34 according to different directions of the elastic member 12 during the rotation.

After the heat-insulating cover plate 11 and the inner cover 10 are separated from each other, the heat-insulating cover plate 11 cannot be continuously abutted against the clamp body 34, and the clamp body 34 is pulled by the stretched or compressed elastic piece 12, so that one end of the clamp body 34 provided with the elastic piece 12 rotates to drive the clamp body 34 to rotate in the opposite direction, and further the clamp body 34 is reset to the first position from the second position, and the locking part 31 is mutually locked with the matching part 21, so that the pot cover 100 and the pot body 110 cannot be locked together, and leak-proof mounting of the pressure cooker is realized.

Further, the elastic member 12 and the thermal insulation cover 11 are disposed on the same side of the card body 34, i.e. the right side of the card body 34 in fig. 1, so that the thermal insulation cover 11 abuts against the card body 34 to drive the card body 34 to rotate counterclockwise, and further drive the card body 34 to compress the elastic member 12. When the heat-insulating cover plate 11 is separated from the card body 34, the card body 34 is driven by the elastic member 12 to rotate clockwise, so as to reset the card body 34.

In the embodiment of the present utility model, referring to fig. 6, 7 and 8, the rim 20 is rotatably installed on the inner cover 10 and includes the first teeth 22, the pot body 110 includes the outer pot 112 and the inner pot 111 installed in the outer pot 112, one of the inner pot 111 includes the second teeth 113, and during the rotation of the rim 20, the first teeth 22 can rotate to the lower side of the second teeth 113, so as to achieve the mutual buckling of the first teeth 22 and the second teeth 113, and the pot cover 100 can be locked with the pot body 110. When the first teeth 22 move between two adjacent second teeth 113, the first teeth 22 can be separated from the pan body 110 between the second teeth 113, so as to separate the ring 20 from the pan body 110, and the pan cover 100 can be opened to open the pan body 110.

It should be noted that, in other embodiments, the second pan teeth 113 may also be disposed on the outer pan 112, and the cover 100 and the pan body 110 may be locked by the mutual fastening of the pan teeth ring 20 and the outer pan 112.

From the above, if the lock of the rim 20 and the pan body 110 needs to be prevented, the lock of the first teeth 22 and the second teeth 113 can be prevented by preventing the rotation of the rim 20, and the lock of the rim 20 and the pan body 110 is also prevented. For this reason, in some embodiments, the mating portion 21 is a mating opening formed on the rim 20, the locking portion 31 is a jack post mounted on the clamp body 34, when the locking portion 31 is interlocked with the mating portion 21, the jack post extends into the mating opening, the rim 20 is blocked by the jack post during rotation, the first teeth 22 and the second teeth 113 cannot be fastened to each other, the lid 100 and the body 110 cannot be locked, and the pressure cooker cannot be started normally.

Specifically, the jack post is installed on the end of the card body 34 for being abutted with the heat preservation cover plate 11 so as to be close to the pan ring 20, when the heat preservation cover plate 11 is abutted with the card body 34, the card body 34 rotates anticlockwise, and the heat preservation cover plate 11 drives the jack post to move in a direction deviating from the pan ring 20, so that the jack post is separated from the matching opening. When the heat-insulating cover plate 11 is separated from the clamp body 34, the clamp body 34 is driven by the elastic piece 12 to rotate clockwise, so that the jack post moves towards the pot tooth ring 20 until the jack post stretches into the matching opening, and locking of the pot tooth ring 20 is completed.

When the heat-insulating cover 11 needs to be detached, the ring 20 and the inner pot 111 can be separated from each other by rotating the ring 20 until the first teeth 22 are located between the two second teeth 113, so as to remove the cover 100 from the pot body 110, and then the heat-insulating cover 11 can be removed from the cover 100. That is, when the heat-insulating cover 11 is removed from the lid 100, the position of the ring 20 relative to the inner lid 10 is fixed, and the top post faces the mating opening, so that the top post enters the mating opening to fix the ring 20.

It should be noted that the mating opening may be a through hole formed in the rim 20, or may be a notch formed in the rim 20, so long as the top post can extend into the rim 20.

In the embodiment, referring to fig. 5 and 12, the inner cover 10 is further provided with a limiting portion 13, the limiting portion 13 is located on a moving path of the card body 34, when the inner cover 10 and the thermal insulation cover 11 are separated from each other, the card body 34 moves to abut against the limiting portion 13, at this time, the card body 34 is located at the first position, and the jack is located in the mating opening, that is, the locking portion 31 and the mating portion 21 are locked with each other. In the actual use process, since the resetting of the card body 34 is completed through the deformation of the elastic member 12, the deformation of the elastic member 12 will generate repeated bouncing, which can cause the card body 34 to repeatedly rotate, and cannot be fixed at the first position.

Therefore, the movement of the card body 34 is limited by the limiting part 13, so that the card body 34 can accurately move to the second position every time the card body 34 is driven by the elastic member 12, and the card body 34 does not repeatedly bounce, thereby ensuring the accuracy of the card body 34 in resetting.

In particular, referring to fig. 1, 9 and 10, when the heat-insulating cover 11 is normally mounted on the inner cover 10, the pressure cooker needs to be started normally, so as to avoid abnormal sound or influence on the normal start of the pressure cooker due to the relative rotation of the card body 34 during normal operation of the pressure cooker. The cover opening buckle 30 further comprises a first protruding portion 32 and a second protruding portion 33 which are arranged on the card body 34, the first protruding portion 32 and the second protruding portion 33 are respectively arranged on two sides of the card body 34, and when the inner cover 10 and the heat insulation cover plate 11 are mutually assembled, the first protruding portion 32 is abutted against the heat insulation cover plate 11 so as to limit the card body 34 to rotate towards the heat insulation cover plate 11 through the abutting of the heat insulation cover plate 11 and the first protruding portion 32. Meanwhile, the second protruding portion 33 can also abut against the pot 110, so as to limit the movement of the card body 34 towards the pot by abutting the pot 110 against the second protruding portion 33. Thus, when the pressure cooker is started normally, the clamp body 34 is fixed between the cooker body 110 and the heat-insulating cover plate 11 and cannot rotate automatically, so that the normal operation of the pressure cooker is ensured.

In particular, referring to fig. 11 and 12, in order to mount the card body 34 on the inner cover 10, two mounting portions 14 are further provided on the inner cover 10, each of the mounting portions 14 is provided with a mounting hole 15, and the card body 34 is rotatably mounted in the two mounting holes 15, so that the card body 34 can rotate between the two mounting portions 14. The two side surfaces of the card body 34 facing the two mounting portions 14 are provided with the protruding blocks 36, and large-area friction between the side surfaces of the card body 34 and the mounting portions 14 can be avoided through the protruding blocks 36, so that the rotation of the card body 34 is smoother.

Further, the cover opening buckle 30 comprises a spring mounting block 37 and two elastic buckles 35, which are arranged on the card body 34, and the elastic piece 12 is sleeved on the spring mounting block 37 so as to fix the elastic piece 12 on the card body 34. The two elastic buckles 35 are respectively fixed in the two mounting holes 15, so that the card body 34 can rotate in the mounting holes 15 through the elastic buckles 35.

The following describes the operation of the pot cover 100 according to the embodiment of the present utility model with reference to fig. 2 and 5:
