Under the drive of the motor 5, the gear 6 meshes and rotates relative to the inner lining 22, and in turn drives the motor 5, the bracket 4 and the annular lock 3 to rotate relative to the inner lining 22, so that the annular lock 3 rotates until the annular lock 3 and the inner pot 11 are in a locked state or an unlocked state. When in use, when the upper cover needs to be locked to the pot body 1, the motor 5 is started, the motor 5 drives the gear 6, the gear 6 meshes and rotates relative to the lining 22, and drives the motor 5, the bracket 4 and the annular lock 3 to rotate relative to the lining 22 in turn, and the annular lock 3 rotates until the annular lock 3 and the inner pot 11 are in a locked state; when the upper cover needs to be unlocked from the pot body 1, the motor 5 is started, the motor 5 drives the gear 6, the gear 6 meshes and rotates relative to the lining 22 in the opposite direction, and drives the motor 5, the bracket 4 and the annular lock 3 to rotate relative to the lining 22 in turn, and the annular lock 3 rotates until the annular lock 3 and the inner pot 11 are in an unlocked state. With such a design, by setting an automatic opening and closing lock structure, the operation of the user when using the rice cooker can be simplified, thereby improving the user's experience.

[0029] In order to achieve locking and unlocking of the annular lock buckle 3 and the inner liner 11, a first pot tooth 111 is provided on the inner liner 11, and a second pot tooth 34 is provided on the annular lock buckle 3. The annular lock buckle 3 and the inner liner 11 are locked or unlocked through the cooperation of the second pot tooth 34 and the first pot tooth 111.

[0030] In order to prevent the bracket 4 from deviating from the preset active position under the drive of the motor 5, limit blocks 226 are provided on both sides of the lining 22 corresponding to the active trajectory of the bracket 4. The limit blocks 226 are used to limit the active position of the bracket 4 so that the bracket 4 can only move within the preset position.

[0031] In some embodiments, in order for the bracket 4 to rotate relative to the liner 22 to drive the annular lock 3 to rotate and lock or unlock relative to the inner liner 11, the annular lock 3 is arranged along the outer periphery of the liner 22, the meshing teeth 221 are arranged in an arc shape on the outer periphery of the liner 22, and the outer periphery of the bracket 4 is an arc shape adapted to the shape of the meshing teeth 221 and is arranged close to the meshing teeth 221. With such a design, the structure between the bracket 4, the annular lock 3 and the liner 22 can be made more compact.

[0032] In order to provide the meshing teeth 221 on the lining 22 , the outer periphery of the lining 22 extends in a direction away from the pot body 1 to form a circumferential wall 222 , and the meshing teeth 221 are provided on the inner wall surface of the circumferential wall 222 .

[0033] Furthermore, the bracket 4 is a block structure, both sides of the bracket 4 are connected to the annular lock 3, the motor 5 is located in the middle area of ​​the bracket 4 and both sides are fixed to both sides of the bracket 4, and the gear 6 is located in the middle area of ​​the bracket 4 and between the motor 5 and the bracket 4. With such a design, the structure among the bracket 4, the motor 5 and the gear 6 can be made more compact.

[0034] Preferably, a first avoidance groove 41 is provided in the middle area of ​​the bracket 4, the motor 5 is located above the first avoidance groove 41, and the gear 6 is partially located in the first avoidance groove 41 to be connected to the motor 5. With such a design, the avoidance groove is provided in the area corresponding to the gear 6 on the bracket 4 to accommodate part of the gear 6, so that the bracket 4 can meet the structural strength while making the structure between the bracket 4 and the gear 6 more compact.

[0035] In some embodiments, the annular locking buckle 3 is located below the lining 22 and is arranged around the inner liner 11, the bracket 4 is located above the lining 22, a first hanging shaft 31 is provided on the annular locking buckle 3, and an arc-shaped second avoidance groove 223 is provided on the lining 22, and the first hanging shaft 31 passes through the second avoidance groove 223 to be connected to the other end of the bracket 4.

[0036] Furthermore, in order to allow the annular lock buckle 3 to be rotatably arranged on the inner lining 22, the inner lining 22 is also provided with an arc-shaped connecting groove 224 for guiding, and the annular lock buckle 3 is provided with a second hanging shaft 32, and the second hanging shaft 32 is slidably arranged in the connecting groove 224. With such a design, when the annular lock buckle 3 rotates driven by the bracket 4, the second hanging shaft 32 slides in the connecting groove 224, so that the annular lock buckle 3 can be installed to rotate along a preset path.

The annular lock 3 is rotatably arranged on the lining 22. The bracket 4 is fixed to the annular lock 3. The motor 5 is fixed to the bracket 4. The gear 6 is arranged on the motor 5 and meshed with the meshing tooth 221. Driven by the motor 5, the gear 6 meshes and rotates relative to the lining 22, and successively drives the motor 5, the bracket 4 and the annular lock 3 to rotate relative to the lining 22, so that the annular lock 3 rotates to a state where the annular lock 3 and the inner pot 11 are in a locked state or an unlocked state. When in use, when it is necessary to lock the upper cover on the pot body 1, the motor 5 is started. The motor 5 drives the gear 6. The gear 6 meshes and rotates relative to the lining 22, and successively drives the motor 5, the bracket 4 and the annular lock 3 to rotate relative to the lining 22. The annular lock 3 rotates to a state where the annular lock 3 and the inner pot 11 are in a locked state. When it is necessary to unlock the upper cover from the pot body 1, the motor 5 is started. The motor 5 drives the gear 6. The gear 6 meshes and rotates in the reverse direction relative to the lining 22, and successively drives the motor 5, the bracket 4 and the annular lock 3 to rotate in the reverse direction relative to the lining 22. The annular lock 3 rotates to a state where the annular lock 3 and the inner pot 11 are in an unlocked state. By adopting such a design method, by setting an automatic opening and closing lock structure, the operation of the user when using the electric rice cooker can be simplified, thereby improving the user experience.
