As shown in fig. 1, 2, 4 and 5, the cooking appliance of the present embodiment includes: the cooker body 10, the cover body 20, the cover tooth assembly 30, the first restoring member 40, the transmission member 50, the lever structure 90 and the driving member 80. Wherein, the pot body 10 is provided with a pot tooth 121; the cover body 20 is arranged on the cooker body 10 in a reversible manner, and the cover body 20 comprises a lining cover 21; the cover tooth assembly 30 is movably arranged on the lining cover 21, and the cover tooth assembly 30 is provided with a locking position locked with the pot teeth 121 and an unlocking position unlocked with the pot teeth 121; the first restoring member 40 is disposed on the cover body 20, and the first restoring member 40 applies a first restoring force to the cover tooth assembly 30 to keep the cover tooth assembly 30 at the unlocking position or the locking position; the transmission piece 50 is pivotally arranged on the lining cover 21, and the transmission piece 50 is in driving fit with the cover tooth assembly 30; the lever structure 90 is pivotally arranged on the cover body 20, and a first end of the lever structure 90 is in driving fit with the transmission piece 50; the driving member 80 is pivotally arranged on the pot body 10, the driving member 80 has a driving part 812, and the driving part 812 is in driving fit with the second end of the lever structure 90; wherein, the lever structure 90 includes a first force arm 91 close to the driving member 80 and a second force arm 92 close to the transmission member 50, and the length L1 of the first force arm 91 and the length L2 of the second force arm 92 satisfy: l1 is more than L2 and L1/L2 is more than 1.1 and less than 3.

With the technical solution of the present embodiment, the cooking appliance includes the driving element 80 disposed on the pot body 10 and the lever structure 90 disposed on the lid body 20, a first end of the lever structure 90 is in driving fit with the driving portion 812 of the driving element 80, and a second end of the lever structure 90 is in driving fit with the transmission element 50. The lever structure 90 is disposed between the driving member 80 and the transmission member 50 in this embodiment, so that the driving force of the driving member 80 can be transmitted to the transmission member 50 through the lever structure 90, and it is not necessary to extend the driving member 80 or dispose the matching portion on the transmission member 50 to realize the driving matching between the driving member 80 and the transmission member 50 as described in the background art, thereby ensuring that the driving force generated by the driving member 80 can be smoothly transmitted to the transmission member 50, realizing the reliable transmission of the driving force, and improving the smoothness of the uncovering process. Meanwhile, the lever structure 90 has a small volume, and is installed in the cover 20, so that the structures of the driving member 80 and the transmission member 50 are simplified, and the structural layout of the inside of the cover 20 is optimized.

Meanwhile, the lever structure 90 of the present embodiment includes a first force arm 91 close to the driving element 80 and a second force arm 92 close to the transmission element 50, a length L1 of the first force arm 91 of the present embodiment is greater than a length L2 of the second force arm 92, the first force arm 91 is disposed close to the driving element 80, and increasing the length of the first force arm 91 can save more labor when the driving element 80 drives the lever structure 90. Under the condition that the user adopts the manual drive driving piece 80 to uncap, the user only needs to exert less power to the driving piece 80 and can open the lid, has further promoted user's use experience.

Specifically, as shown in fig. 2 and 4, in the present embodiment, the length L1 of the first force arm 91 and the length L2 of the second force arm 92 satisfy: l1 is more than L2 and L1/L2 is more than 1.3 and less than 1.7. In the above structure, if the value of L1/L2 is too large, it indicates that the difference between the length L1 of the first force arm 91 and the length L2 of the second force arm 92 is too large, which may cause the lever structure 90 to rotate a large angle to drive the transmission member 50 to move to the predetermined position, and the large angle of rotation of the lever structure 90 may occupy a large space in the cover body, which is not favorable for the miniaturization design of the cover body. Therefore, the requirement that the ratio of 1.3 to L1/L2 to 1.7 is more than 1.3 is required to be ensured, on one hand, the effect of saving labor during uncovering can be achieved, and on the other hand, the effect of enabling the design of the cover body to be more miniaturized can also be achieved. The ratio of L1/L2 may be 1.3, 1.5, 1.6, or 1.7. Preferably, the ratio L1/L2 is 1.5.

Of course, in other embodiments, the length L1 of the first force arm 91 and the length L2 of the second force arm 92 may also satisfy: l1 is more than L2 and 0.5 is more than L1/L2 is less than 0.9. Because the second moment arm 92 is disposed close to the transmission member 50, the length of the second moment arm 92 is greater than the length of the first moment arm 91, so that the moving distance of the second end of the lever structure 90 during transmission can be increased, and the lever structure 90 can drive the transmission member 50 to move a longer distance only by rotating a smaller angle. Under the condition that the user adopts manual drive driving piece 80 to uncap, the user only needs drive lever structure 90 to rotate less angle and can open the lid, has further promoted user's use and has experienced. Preferably, 0.6 < L1/L2 < 0.8. In the above structure, if the value of L1/L2 is too small, it indicates that the length L1 of the first force arm 91 is much smaller than the length L2 of the second force arm, which may cause the user to press the lid opening structure with more effort. Therefore, the L1/L2 is more than 0.6 and less than 0.8, on one hand, the second force arm 92 of the lever structure 90 has larger torque, so that the transmission member 50 is easy to drive, and on the other hand, the pressing hand feeling of the user pressing the driving member 80 can also be ensured. The value of L1/L2 may be 0.6, 0.7, 0.75, or 0.8. Further preferably, the value of L1/L2 is 0.75.

As shown in fig. 2, in the present embodiment, the maximum rotation angle of the lever structure 90 is between 5 ° and 30 °. In the above structure, if the rotation angle of the lever structure 90 is too large, a large swing space needs to be reserved for the lever structure 90 when designing the cover body, which affects the miniaturization design of the cover body. If the rotation angle of the lever structure 90 is too small, the transmission member 50 is not easy to be pushed in place, so that the cover tooth assembly 30 cannot be completely moved to the unlocking position, and the cover opening effect is affected. Therefore, the maximum rotation angle of the lever structure 90 is required to be set between 5 ° and 30 °, and the swing space of the lever structure 90 is reduced without affecting the cover opening effect, so that the cover design is more miniaturized.

Specifically, as shown in fig. 2, in the present embodiment, since the length L1 of the first force arm 91 is greater than the length L2 of the second force arm 92, the maximum rotation angle of the lever structure 90 is between 10 ° and 30 °. Above-mentioned structure can make the user laborsaving easily when triggering the driving piece on the one hand, and on the other hand lever structure 90 need not to rotate too big angle and can drive lid tooth subassembly 30 and remove to the unblock position, has guaranteed the miniaturization of lid design.

Of course, in other embodiments, the maximum angle of rotation of the lever structure 90 is between 5 ° and 25 ° in the case where the length L1 of the first force arm 91 is less than the length L2 of the second force arm 92. In the above configuration, the length L2 of the second force arm 92 is relatively long, so that the cover tooth assembly can be driven into position by rotating the lever structure 90 by a relatively small angle.

As shown in fig. 1 to 6, in the present embodiment, the first restoring member 40 applies a first restoring force to the cover tooth assembly 30 to keep the cover tooth assembly 30 at the unlocked position, the second end of the lever structure 90 is drivingly engaged with the transmission member 50, the driving member 80 has a limit position in which the driving portion 812 pushes the lever structure 90 inward and an avoidance position in which the driving portion 812 avoids the lever structure 90 outward, and when the driving member 80 is located at the limit position and drivingly engaged with the first end of the lever structure 90, the driving member 80 drives the cover tooth assembly 30 to move to the locked position through the lever structure 90 and the transmission member 50; when the driving member 80 is in the retracted position, the cover tooth assembly 30 is moved to the unlocking position by the first restoring member 40. When the cover body 20 is in the open state, the cover tooth assembly 30 is maintained at the unlocking position by the first restoring force generated by the first restoring member 40, and the cover tooth assembly 30 is in a state of being misaligned with the pot teeth 121. In the above structure, as shown in fig. 4 to fig. 6, after the user covers the cover body 20 on the pot body 10, the driving element 80 on the pot body 10 can be kept at the limit position, at this time, the driving portion 812 on the driving element 80 can drive the first end of the lever structure 90 to swing inward, since the lever structure 90 is pivotally disposed on the lining cover 21, the first end of the lever structure 90 swings inward, so that the second end of the lever structure 90 drives the transmission element 50 to move outward, and the transmission element 50 can drive the cover tooth assembly 30 to move to the lock position, thereby enabling the cover tooth assembly 30 to be locked with the pot teeth 121. As shown in fig. 1 to 3, when a user needs to open the lid 20, the driving member 80 is triggered to move from the limiting position to the avoiding position, at this time, the driving portion 812 of the driving member 80 no longer interferes with the position of the lever structure 90, at this time, the cover tooth assembly 30 can move from the locking position to the unlocking position under the effect of the first restoring force of the first restoring member 40, at this time, the cover tooth assembly 30 is in a state of being dislocated from the pot teeth 121, and the lid 20 can be opened from the pot body 10 (a pivot and a torsion spring are disposed between the lid 20 and the pot body 10, so that the lid 20 and the pot body 10 can be automatically opened). With the above structure, when a user presses the cover body 20 on the cooker body 10, the pot teeth 121 and the cover teeth assembly 30 can be locked, and when the user wants to open the cover body 20, the user only needs to trigger the driving member 80, so that the pot teeth 121 and the cover teeth assembly 30 can be unlocked. The structure enables the cover closing process and the cover opening process of a user to be simpler and more convenient, and improves the use experience of the user.

It should be noted that, in the above structure, the first restoring member 40 always applies the first restoring force to the cover tooth assembly 30, so that the cover tooth assembly 30 always tends to move toward the unlocking position. During uncovering, the driving piece 80 also needs to drive the lever structure 90 to enable the cover tooth assembly 30 to move to the unlocking position, so that the cover tooth assembly 30 is pulled to the unlocking position by the first resetting piece 40 during uncovering, and a user can realize the unlocking effect of the cover tooth assembly 30 and the pot teeth 121 by only using smaller force to trigger the driving piece 80.

In the above structure, the cover tooth assembly 30 locked and unlocked with the pot teeth 121 and the clamping table 211 clamped and matched with the driving member 80 on the pot body 10 are arranged on the cover body 20. When the user covers the cover body 20 on the pot body 10, the cover tooth assembly 30 on the cover body 20 can be locked with the pot teeth 121, and the clamping table 211 can be in limit locking with the driving part 812 of the driving part 80, so that the double locking of the cover body 20 and the pot body 10 is realized. When the user needs to open the lid body 20, the end of the lid opening lever 81, which is far away from the hook portion, can be pressed to move the driving member 80 from the limit position to the avoiding position, and at this time, the hook portion loses the clamping fit with the clamping table 211, thereby realizing the first re-unlocking of the cooker body 10 and the lid body 20. Meanwhile, when the driving member 80 is located at the avoiding position, the hook portion can also avoid the second end of the lever structure 90, and at this time, the first resetting member 40 drives the transmission member 50 to move inwards through the first resetting force, so that the cover tooth assembly 30 is located at the unlocking position, and the second unlocking of the cooker body 10 and the cover body 20 is realized. The above structure can realize double locking and unlocking of the lid 20 and the pot body 10, thereby ensuring the stability of locking the lid 20 and the pot body 10.

In the structure, the length of the fourth force arm is greater than that of the third force arm, and the fourth force arm is abutted to the uncovering key 83, so that the user can save more labor when the uncovering key 83 is driven, and the use experience of the user is further improved.

As shown in fig. 1 to 6, in the present embodiment, the transmission member 50 includes a sliding plate, an end of the sliding plate is movably hinged to the second end of the lever structure 90, the sliding plate is in driving engagement with the cover tooth assembly 30, and when the sliding plate moves outward, the sliding plate drives the cover tooth assembly 30 to move to the locking position. Specifically, the second end of the lever structure 90 is hinged to the transmission plate, when the driving member 80 is located at the limiting position, the first end of the lever structure 90 swings inwards and the second end swings outwards, and when the driving member 80 is located at the avoiding position, the first end of the lever structure 90 swings outwards and the second end swings inwards. The above structure can improve the stability of the driving engagement of the transmission member 50 with the lever structure 90.
