When the pot cover 300 returns to the initial position, the two driving rods are abutted against the top plate 341; when the lid 300 moves to the closing position, the two driving rods are abutted against the transverse plate or the protruding block, so that the driving motor 330 is limited to continue to rotate.

The following is the course of action of the dual lever structure 310 to actuate the lid 300 once between the initial position and the closed position:

the pot cover 300 is in the initial position, and if the pot cover needs to be covered with a pot opening to be matched with a frying pot for cooking:

the frying pan is turned backwards (the turning angle is preferably 60 DEG) so that the pan opening of the frying pan rotates from an upward position to a position facing the pan cover 300 arranged behind the frying pan;

the main control circuit of the cooker controls the driving motor 330 to start, the output shaft drives the left driving rod 311 and the rotating shaft 315 to drive the right driving rod 313 to rotate clockwise (anticlockwise/clockwise: right-to-left view, lower same) so as to drive the rear end of the corresponding driven rod to rotate clockwise around the connecting shaft 316, the front end of the driven rod applies forward thrust to the corresponding support leg 302, and under the action of the thrust, the support leg 302 drives the backboard 301 and other parts in the pot cover 300 to rotate forwards and downwards around the central line of the hinge hole of the support leg 302 from a vertical state, the moving track of the pot cover 300 and the support leg 302 is in a circular arc shape with a central angle of 30 degrees, at the moment, the pot cover 300 reaches a covering position, and the pot cover is tightly buckled on the pot mouth.

If the pot mouth needs to be opened:

the driving motor 330 drives the two driving rods to rotate anticlockwise, the rear ends of the two driven rods rotate clockwise around the connecting shaft 316 under the driving of the driving rods, and the rear ends of the two driven rods pull the support legs 302, so that the pot cover 300 is retracted to the vertical state from the inclined state along the arc-shaped path when the pot cover 300 extends, namely, the pot cover 300 returns to the initial position.

2) Gear transmission structure

As shown in fig. 3 and 4, the gear transmission structure is composed of a driving gear 321 and a driven gear 322, which are preferably cylindrical gears, and in order to facilitate the installation of the mechanical limiting structure, the driven gear 322 is preferably semicircular, and the driven gear 322 is located at the front lower part of the driving gear 321 and can be externally meshed with the driving gear 321.

The number of the gear transmission structures is two, and the gear transmission structures are symmetrically arranged on the left side and the right side in the cavity of the base respectively, and have the same structure and size.

The left and right driving gears 321 are mounted on the upper portion of the side plate of the base through a rotation shaft 326 in the same manner as the mounting manner between the left driving lever 311, the right driving lever 313 and the base, and will not be described again here.

Preferably, in order to improve stability of the leg when moving, a circular cap button may be added to the inner end surface of the guide block 323, which buckles the leg between the end surface of the driven gear 322 and the leg.

The driven gear 322 rotates counterclockwise, and the guide block 323 slides upward in the corresponding guide hole 324; the driven gear 322 rotates clockwise, the guide hole 324 slides down along with it, and the guide block 323 applies external force in the front-back direction to the support leg during sliding to drive the pot cover to move.

Preferably, the end position of the downward sliding of the guide block 323 (when the pot cover rotates to the covering position) is the bottom end of the guide hole 324, that is, the guide hole 324 plays a limiting role, so as to restrict the pot cover to move forward continuously; in order to stabilize the lid in the initial position, a limit stop 325 for limiting the driven gear 322 from continuing to rotate counterclockwise is installed on the left and right side plates of the base at the front lower side of the driven gear 322.

The following is the action process of the gear transmission structure driving the pot cover to switch once between the initial position and the closing position:

the pot cover is in an initial position, the gear teeth at the front ends of the driving gear 321 and the corresponding driven gear 322 are in a state to be meshed, and if a pot opening needs to be covered, the driving motor is started:

During disassembly, the positioning pin 307 is pressed, and then the adapter plate 305 is rotated to separate the clamping plate from the corresponding clamping block, so that the cover-carrying plate 303 of the adapter plate 305 and the rotating assembly can be wholly disassembled from the fixing seat 306, and the assembly is quite convenient.

A smoke inlet and an elliptic seasoning injection port are formed in the middle area of the adapter plate 305, smoke holes and material holes corresponding to the smoke inlet and the seasoning injection port are formed in the fixing seat 306 respectively, and oil smoke in the cooker enters an oil smoke treatment module of the cooker through a gas pipeline connected with the smoke holes and the smoke inlet for filtering and purifying; the seasoning hole is provided with a seasoning conveying pipe 610 extending forwards, the seasoning conveying pipe 610 can be inserted into a seasoning injection hole, a space allowing the adapter plate 305 to rotate for a certain angle is reserved between the seasoning conveying pipe 610 and the wall of the strip-shaped hole, and seasoning required for cooking is added into the frying pan through the seasoning conveying pipe 610.

The back plate 301 is fixedly connected to the back surface of the fixing seat 306, and an opening corresponding to the smoke inlet and allowing the air pipe and the seasoning conveying pipe 610 to pass through is formed in the back plate 301.

When the pot cover 300 is in the cover position, the cover plate 303 is matched and buckled on a pot opening of the frying pot to seal, and in the rotary cooking process of the frying pot, the cover plate 303 is driven to carry the rotary component and the cover ring 304 to synchronously rotate.

Through the arrangement, the pot cover assembly is stably installed in the cooking cavity, the installation among all the parts is very compact, and the occupied space in the cooking cavity can be reduced;

by setting the moving track of the pot cover 300 to be circular arc, the area enclosed by the moving track of the supporting leg 302 when moving is a sector with the central angle of 30 degrees, the lower part of the pot cover almost occupies no space when moving, and compared with the existing scheme of driving the pot cover 300 to move linearly through complex structures such as a gear structure or a push rod structure (the pot cover 300 needs to be set to be in an inclined state when being installed, the arrangement occupies a part of available cooking cavity space, and the area enclosed by the moving track when moving is a parallelogram), the pot cover assembly has the advantages of small occupied space and high space utilization rate; the pot cover 300 automatically retracts when not required to be buckled on the pot mouth, so that space is reserved for the cooperation of other devices in the cooking machine and the frying pot, and the double-connecting-rod structure 310 and the pot cover 300 are in vertical states when returning to the initial positions, so that the occupied space of the pot cover assembly is further reduced, and the space utilization rate is improved.
