It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

As shown in fig. 1 to 10, the cooking appliance of the present embodiment includes: the instrument body 10, the upper cover 20, the locking assembly, the slider 70 and the driving member 60. Wherein, the pot teeth 121 are arranged on the appliance main body 10; the upper cover 20 is covered on the device main body 10 in a reversible way, and the upper cover 20 comprises a lining cover 21; the locking assembly is arranged on the lining cover 21 and comprises a locking state locked with the pot teeth 121 and an unlocking state unlocked with the pot teeth 121; the driving member 60 is movably disposed on the appliance main body 10, the driving member 60 has a driving portion, and the driving portion is provided with a first inclined surface 6121 and a planar structure 6122 connected to the first inclined surface 6121; the sliding block 70 is movably disposed on the lining cover 21 along the vertical direction, a first end of the sliding block 70 is provided with a second inclined surface 711 in driving fit with the first inclined surface 6121 of the driving member 60, the locking assembly is provided with an installation hole 411, and a second end of the sliding block 70 penetrates through the installation hole 411 and is in driving fit with an outer hole wall of the installation hole 411 through an inclined surface structure. When the upper cover 20 is closed on the device body 10, the driving part of the driving element 60 and the sliding block 70 trigger the driving cooperation to switch the locking assembly from the unlocking state to the locking state.

By applying the technical solution of the present embodiment, when the user presses the upper cover 20 onto the appliance main body 10, the driving member 60 can be in driving engagement with the sliding block 70, so that the sliding block 70 drives the locking assembly to switch from the unlocking state to the locking state, thereby realizing automatic locking of the pot teeth 121 and the locking assembly. The structure enables a user to realize the automatic locking of the pot teeth 121 and the locking component only by performing one-step operation of pressing the upper cover 20 onto the appliance main body 10, and the user does not need to place the upper cover 20 onto the appliance main body 10 first and then rotate the upper cover 20 to realize the locking of the upper cover and the appliance main body 10 as described in the background art, thereby simplifying the step of locking the cover by the user and improving the use experience of the user. The slider 70 is slidably provided on the pad cover, and can transmit the driving force and also change the direction of the force. Specifically, when the upper cover is pressed downward onto the appliance body, the first inclined surface 6121 of the driving member 60 is in driving fit with the second inclined surface 711 of the slider 70, so as to push the slider 70 upward, and the slider 70 is in driving fit with the locking assembly through an inclined surface structure, so that the locking assembly is switched from an unlocking state to a locking state, and the upper cover and the appliance body are locked. When the upper cover is covered on the main body of the device, the bottom of the slider 70 is pushed and matched with the plane structure 6122, so that the slider 70 can be stably kept in a floating state. In the process of pressure cooking, when the locking assembly has a tendency of moving from the locking state to the unlocking state, the locking assembly applies a downward force to the slider 70, and since the bottom of the slider 70 abuts against the flat structure 6122, the locking assembly is difficult to move to the unlocking state, so that the locking assembly can be stably kept at the locking position when the cooking appliance works, and the safety of the cooking appliance is improved.

In order to stably connect the upper cover 20 to the device body 10, the upper cover is generally closed to the device body 10 by a double locking method. Specifically, the first locking manner is: the upper cover is provided with cover teeth, the appliance main body is provided with pot teeth, and the cover teeth and the pot teeth are locked in a screwing mode. The second locking mode is to arrange a first limiting part on the appliance main body and a second limiting part on the upper cover, and when the upper cover is covered on the appliance main body, the first limiting part and the second limiting part can be in limiting fit, so that locking is realized. In order to realize the double locking of the upper cover and the appliance main body, as shown in fig. 1 to 10, in the present embodiment, the lining cover 21 is provided with a clamping table 211, the driving lever 61 includes a rod body 611 and a hook portion 612 which is in snap fit with the clamping table 211, the hook portion 612 forms a driving portion, the driving lever 61 has a snap fit state which enables the hook portion 612 to be in snap fit with the clamping table 211 and an escape state which enables the hook portion 612 to be disengaged from the clamping table 211; a lever restoring member 62 disposed between the device body 10 and the rod body 611, the lever restoring member 62 applying a first restoring force to the driving lever 61 to maintain the driving lever 61 in a fastened state; when the driving lever 61 is in the buckling state, the driving lever 61 drives the locking component to be in the locking state through the sliding block 70; when the actuating lever 61 is in the retracted state, the locked assembly is in the unlocked state. In the above structure, after the user closes the upper cover 20 on the appliance main body 10, the hook portion 612 of the driving lever 61 on the appliance main body 10 can be engaged with the engaging platform 211, and simultaneously the slider 70 can be triggered, so that the slider drives the locking assembly to switch from the unlocked state to the locked state, thereby achieving the double locking of the upper cover 20 and the appliance main body 10.

As shown in fig. 1 to 10, the locking assembly includes: a caliper structure 30 movably provided on the liner cover 21 in a radial direction of the liner cover 21; the cover tooth resetting piece 50 is arranged on the upper cover 20, and the cover tooth resetting piece 50 applies a second resetting force to the caliper structure 30 so that the caliper structure 30 is kept in an unlocked state when the upper cover 20 is opened; a transmission member 40 movably disposed on the liner cover 21, wherein a first end of the transmission member 40 is in driving engagement with a second end of the slider 70, and a second end of the transmission member 40 is in driving engagement with the caliper structure 30; wherein, when the driving lever 61 is in the fastening state, the driving lever 61 drives the caliper structure 30 to be in the fastening state through the slider 70 and the transmission member 40; when the actuating lever 61 is in the retracted state, the caliper structure 30 is in the unlocked state by the cover tooth reset element 50. It should be noted that when the caliper structure 30 is in the unlocked state, the entire locking assembly is in the unlocked state, and when the caliper structure 30 is in the locked state, the entire locking assembly is in the locked state. In the above structure, after the user closes the upper cover 20 on the appliance main body 10, the hook portion 612 of the driving lever 61 can be engaged with the engaging platform 211, and simultaneously the slider 70 can be triggered, and the slider 70 drives the caliper structure 30 to switch from the unlocked state to the locked state through the transmission member 40, so as to achieve double locking of the cover and the cooker body.

The above-mentioned "the cover tooth returning element 50 applies the first returning force to the caliper structure 30" may include the cover tooth returning element 50 directly applying the first returning force to the caliper structure 30, or may include the cover tooth returning element 50 applying the first returning force to the caliper structure 30 through other structures (such as transmission members in the present embodiment, which will be described in detail later).

The above-mentioned "the cover tooth returning piece 50 applies the first returning force to the caliper structure 30 to maintain the caliper structure 30 in the unlocked state" means that the caliper structure 30 can be located in the unlocked state when the caliper structure 30 is subjected to only the first returning force.

In the above-described "retreat state of retreating the driving portion outward from the catch 211", the "outward" refers to a direction away from the vertical center line of the cooking appliance, and correspondingly, the "inward" refers to a direction close to the vertical center line of the cooking appliance.

Specifically, in the present embodiment, the upper cover 20 is provided with a caliper structure 30 for locking and unlocking with the pot teeth 121, and a locking platform 211 for locking and unlocking with the driving lever 61 on the appliance main body 10. When the user closes the upper cover 20 on the appliance main body 10, the caliper structure 30 on the upper cover 20 can be locked with the pot teeth 121, and the clamping platform 211 can be in limit locking with the hook part of the driving lever 61, so that double locking of the upper cover 20 and the appliance main body 10 is realized. Specifically, as shown in fig. 6 to 10, when the upper cover 20 is in the open state, the caliper structure 30 is maintained in the unlocked state by the first restoring force generated by the cover teeth restoring member 50, and at this time, the caliper structure 30 is in a state of being misaligned with the pot teeth 121. As shown in fig. 1 to 5, when the user closes the upper cover 20 on the device body 10, the driving lever 61 on the device body 10 can be kept in the engaged state, and at this time, the driving portion on the driving lever 61 can be in stop engagement with the catch 211, so that the limit locking of the device body 10 and the upper cover 20 is realized. Meanwhile, when the driving lever 61 is in a locked state, the hook portion of the driving lever 61 can drive the slider 70 to slide upwards, the slider 70 can drive the transmission member 40 to move outwards when floating upwards, and the transmission member 40 can drive the caliper structure 30 to move to a locked position, so that the caliper structure 30 and the pot teeth 121 are locked. As shown in fig. 6 to 10, when a user needs to open the upper cover 20, the driving element 60 may be triggered to move from the engaging state to the avoiding state, at this time, the driving portion on the driving element 60 loses the limit fit with the catch 211, and the hook portion of the driving lever 61 no longer interferes with the position of the slider 70, at this time, the caliper structure 30 can move from the engaging state to the unlocking state under the first restoring force of the cover tooth restoring element 50, the caliper structure 30 is in the state of being dislocated from the pot tooth 121, and the upper cover 20 can be opened from the appliance main body 10 (a pivot and a torsion spring are provided between the upper cover 20 and the appliance main body 10, so as to achieve automatic opening of the upper cover 20 and the appliance main body 10). When a user presses the upper cover 20 on the appliance main body 10, the double locking of the appliance main body 10 and the upper cover 20 (the locking of the pot teeth 121 and the caliper structure 30 and the limit matching of the driving lever 61 and the clamping table 211) can be realized, when the user wants to open the upper cover 20, the driving piece 60 is only needed to be triggered, the double unlocking of the appliance main body 10 and the upper cover 20 can be realized (the pot teeth 121 and the caliper structure 30 are unlocked, and the driving lever 61 does not stop the clamping table 211 any more), so that the cover closing process and the cover opening process of the user are simpler and more convenient.

It should be further noted that, in the above-mentioned "the caliper structure 30 has an unlocked state that is dislocated from the pot teeth 121", the "dislocation" may include that the caliper structure 30 and the pot teeth 121 are dislocated in the circumferential direction of the appliance main body 10 (the pot teeth may be a pot mouth flange, or may be a plurality of pot mouth flanges that are arranged at intervals, and may not be an annular flange), or may include that the caliper structure 30 and the pot teeth 121 are dislocated in the radial direction of the appliance main body 10 (the pot teeth may be a pot mouth flange, or may be a plurality of pot mouth flanges that are arranged at intervals, or may be an annular flange).

As shown in fig. 2, 5, 7 and 10, in the present embodiment, the slope structure includes a third slope surface 4111 disposed on the outer hole wall of the mounting hole 411 and a fourth slope surface 721 disposed at the second end of the slider 70, and the second slope surface 711 of the slider 70 is inclined in a direction opposite to that of the fourth slope surface 721. In the above structure, the slider 70 realizes the change of the direction of the force through the second inclined surface 711 and the fourth inclined surface 721 which are opposite in direction, and the structure is simple, the processing is convenient, and the matching is stable.

Specifically, as shown in fig. 6 to 10, when the upper cover 20 is in the open state, the caliper structure 30 is maintained in the unlocked state by the first restoring force generated by the cover teeth restoring member 50, and at this time, the caliper structure 30 is in a state of being misaligned with the pot teeth 121. As shown in fig. 1 to 5, when the user closes the upper cover 20 on the device main body 10, the driving member 60 on the device main body 10 can be kept in the engaged state, and at this time, the driving portion on the driving member 60 can be brought into stop engagement with the locking platform 211, so as to achieve the limit locking of the device main body 10 and the upper cover 20. Meanwhile, when the driving lever 61 is in the fastened state, the first inclined surface 6121 of the hook portion 612 pushes the second inclined surface 711 of the slider 70 inwards, the slider 70 can move upwards, and at this time, the fourth inclined surface 721 located at the second end of the slider 70 can push the third inclined surface 4111 of the transmission member 40 outwards, so that the transmission member 40 moves outwards, and the transmission member 40 can drive the caliper structure 30 to move to the locked position, so that the caliper structure 30 can be locked with the pot teeth 121. As shown in fig. 6 to 10, when a user needs to open the upper cover 20, the driving lever 61 is triggered to switch from the engaging state to the avoiding state, at this time, the hook portion of the driving lever 61 loses the limit engagement with the locking platform 211, and the hook portion of the driving lever 61 does not interfere with the position of the slider 70 any more, at this time, the caliper structure 30 can move from the engaging state to the unlocking state under the first restoring force of the cover tooth restoring member 50, the caliper structure 30 drives the transmission member 40 to move inward, the fourth inclined surface 721 of the slider 70 moves downward under the pushing force of the third inclined surface 4111 of the transmission member 40, and the transmission member 40 can be located on the moving path of the hook portion 612, so that the hook portion 612 and the slider 70 are pushed to engage when the cover is closed. At this time, the caliper structure 30 is in a state of being misaligned with the pot teeth 121, and the upper cover 20 can be opened from the device body 10 (a pivot and a torsion spring are provided between the upper cover 20 and the device body 10, so that the upper cover and the device body are automatically opened). The slider 70 is arranged in a floating manner by the structure and is matched with the first inclined plane structure and the second inclined plane structure, so that the stability of driving force transmission is improved.

As shown in fig. 2, 5, 7, and 10, in the present embodiment, the length of the fourth slope 721 is greater than the length of the second slope 711. In the above structure, the slider 70 is in pushing fit with the transmission member 40 when the upper cover 20 is in the covering state and the opening state, so that the length of the fourth inclined surface 721 is increased to improve the stability of the fit between the fourth inclined surface 721 and the third inclined surface 4111, thereby improving the driving stability between the transmission member 40 and the slider 70.

As shown in fig. 2 and 7, in the present embodiment, the slider 70 includes a sliding rod 71 and a driving rod 72 disposed at the top of the sliding rod 71 and disposed at an angle to the sliding rod 71, the sliding rod 71 is disposed through the lining cover 21, and an outer end surface of the driving rod 72 forms a fourth inclined surface 721. In the above structure, the driving rod 72 is provided on the sliding rod 71 to facilitate the pushing engagement between the slider 70 and the transmission member 40. The thickness of the driving rod 72 may be greater than that of the sliding rod 71, so as to help increase the length of the fourth inclined surface 721, and thus to improve the stability of the engagement between the fourth inclined surface 721 and the third inclined surface 4111.

It should be noted that, the second reset force applied by the driving lever resetting piece 62 to the driving lever 61 is greater than the first reset force applied by the cover tooth resetting piece 50 to the caliper structure 30, so as to ensure that when the upper cover 20 is covered on the device main body 10, the driving lever 61 can overcome the first reset force applied by the cover tooth resetting piece 50 to the caliper structure 30, so that the driving lever 61 is kept in the engaged state, and thus the driving lever 61 drives the caliper structure 30 to be kept in the locking position through the first transmission piece and the transmission piece.

Because the clamping table 211 and the hook part have a pushing and matching process, the smoothness of the cover closing process of a user can be improved by matching the top of the hook part and the bottom of the clamping table 211 through an inclined surface structure, and therefore the use experience of the user is improved.

Specifically, the upper cover 20 is pivotably provided on the appliance main body, and is connected to the appliance main body 10 by a torsion spring. When the user closes the cover 20, the fifth inclined surface 2111 on the catch 211 can push the hook portion outward, so that the driving lever 61 is switched from the engaged state to the retracted state. After the upper cover 20 continues to move downwards, the fifth inclined surface 2111 loses the pushing force on the first inclined surface 6121, the hook portion moves inwards, the driving lever 61 returns to the buckling state from the avoiding state, the hook portion is located above the clamping table 211 at the moment, the upper cover 20 has the tendency of moving upwards under the action of the torsion spring, and the hook portion can form a stop for the clamping table 211 so that the upper cover 20 is kept at the covering position.
