[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the protection scope of the present invention.

[0032] Please refer to the attached Figures 1-11 , a stir-frying mechanism in an embodiment of the present invention includes a fixed bracket 1, a rotating shaft 3 connected to the fixed bracket 1 through a bearing, a driving mechanism provided on the fixed bracket 1 and used to drive the rotation of the rotating shaft 3, a disc 7 connected to the rotating shaft 3 through a flat key 31, a first linkage rod 6 and a second linkage rod 4 sleeved on the rotating shaft 3. In this way, when the rotating shaft 3 rotates, the disc 7 will rotate along with the rotating shaft 3, while the first linkage rod 6 and the second linkage rod 4 do not rotate with the rotating shaft 3; a spatula module is provided on the first linkage rod 6, and a pot lid module is provided on the second linkage rod 4. In this way, when the driving mechanism drives the rotating shaft 3 to rotate, the spatula module and the pot lid module can be driven to rotate around the rotating shaft 3 through the first linkage rod 6 and the second linkage rod 4.

[0033] A first limiting block 13 and a second limiting block 15 are respectively provided in front of and below the rotating shaft 3 on both sides of the fixed bracket 1, and a first limiting groove 14 and a second limiting groove 16 are respectively provided on the first limiting block 13 and the second limiting block 15; symmetrically structured first arc-shaped sliding grooves 71 and second arc-shaped sliding grooves 73 are provided on the disc 7, and first clamping grooves 72 and second clamping grooves 74 are respectively formed at the opposite ends of the first arc-shaped sliding groove 71 and the second arc-shaped sliding groove 73 extending towards the rotating shaft 3 direction;

[0034] A first through hole 62 corresponding to the position and a first pressing component perpendicular to the rotating shaft 3 are provided on the first linkage rod 6. A first limiting rod 63 penetrates through the first through hole 62, and the first pressing component presses the first limiting rod 63, and the first limiting rod 63 also penetrates through the first arc-shaped sliding groove 71; a second through hole 43 corresponding to the position of the second clamping groove 74 and a second pressing component perpendicular to the rotating shaft 3 are provided on the second linkage rod 42. A second limiting rod 42 penetrates through the second through hole 43, and the second pressing component presses the second limiting rod 42, and the second limiting rod 42 also penetrates through the second arc-shaped sliding groove 73.

[0035] At first, when the device of the present invention is not working, both the spatula module and the pot lid module are in an upright state, that is, both the first linkage rod 6 and the second linkage rod 4 are in an upright state. Among them, the spatula module is located inside the pot lid module. Under the action of the first pressing component, the first limiting rod 63 is located in the first clamping groove 72 and directly above the rotating shaft 3, while the second limiting rod 42 is located at one end of the second arc-shaped sliding groove 73 that is not the second clamping groove 74, and the end of the second limiting rod 42 is located in the second limiting groove 16. Moreover, the second limiting rod 42 is directly below the rotating shaft 3, as Figure 4 shown.

[0036] When the driving module works, the driving module can drive the rotating shaft 3 to rotate clockwise. The disc 7 rotates along with the rotating shaft 3. Under the action of the first clamping groove 72 of the disc 7, the first limiting rod 63 is toggled to rotate, that is, the first linkage rod 6 is driven to rotate clockwise along with the rotating shaft 3. And under the action of the second arc-shaped sliding groove 73, the disc 7 will not directly drive the second limiting rod 42 to rotate, that is, it will not drive the second linkage rod 4 to move. When the rotating shaft 3 rotates by 90 degrees, the first limiting rod 63 moves to the bottom end of the first limiting groove 14 and the first limiting rod 63 disengages and is located in the first arc-shaped sliding groove 71, and the notch of the second clamping groove 74 moves to the position of the second limiting rod 42. That is, the first linkage rod 6 rotates 90 degrees clockwise along with the rotating shaft 3, and the first linkage rod 6 can drive the spatula module to move downward. And the second limiting rod 42 is not squeezed into the second clamping groove 74 by the second pressing component under the action of the second limiting groove 16, so that the second linkage rod 4 still remains in an upright state, as Figure 5 shown.

[0037] At this time, when the driving mechanism continues to drive the rotating shaft 3 to rotate clockwise, the disc 7 rotates along with the rotating shaft 3. Under the action of the first arc-shaped sliding groove 71, the disc 7 will not drive the first limiting rod 63 to rotate, that is, it will not drive the first linkage rod 6 to move. And the second limiting rod 42 is toggled under the action of the end of the second arc-shaped sliding groove 73, that is, the second linkage rod 4 is driven to rotate clockwise along with the rotating shaft 3, so that the second limiting rod 42 moves out of the second limiting groove 16 and is located in the second clamping groove 74 under the action of the second pressing component. When the rotating shaft 3 rotates by 180 degrees, the position of the first linkage rod 6 remains unchanged, the first limiting rod 63 is located at one end of the first arc-shaped sliding groove 71 that is not the first clamping groove 72, while the second limiting rod 42 is located in the second clamping groove 74, and the second linkage rod 4 rotates 90 degrees clockwise along with the rotating shaft 3, as Figure 6 shown, that is, the second linkage rod 4 drives the pot lid module to move downward. In the above state, when the pot lid module and the spatula module are not in use, by controlling the driving mechanism to drive the rotating shaft to rotate counterclockwise, according to the same principle as above, the pot lid module can first move upward to an upright state, and then the spatula module can move upward to an upright state, so that the present invention returns to the initial state.

[0038] In an embodiment of the present invention, the driving mechanism includes a first motor 21, a first gear 43 connected to the rotating shaft of the first motor 21, and a second gear 44 connected to the rotating shaft 3. The first gear 43 and the second gear 44 are connected by a chain 42. A first mounting seat 12 is provided on the fixed bracket 1, and the first motor 21 is mounted on the first mounting seat 12. Thus, the rotation of the first gear 43 can be driven by the rotating shaft of the first motor 21, and the rotation of the second gear 44 can be linked through the chain 42. In this way, the rotating shaft can be driven by the driving mechanism.

[0039] In an embodiment of the present invention, the spatula module includes a first swing arm 51, a spatula member, and a second mounting seat 53 provided at the end of the first swing arm 51. A second motor 51 is provided on the second mounting seat 53. The rotating shaft of the second motor 51 is connected to the spatula member through a coupling. The first swing arm 51 is mechanically connected to the first linkage rod 6. In this way, when the first linkage rod 6 rotates, the entire spatula module can be driven to move up and down, and the rotation of the spatula member can be driven by the operation of the second motor 51 to realize the function of stir-frying.

[0040] In an embodiment of the present invention, a first sensing piece 55 is provided on the first swing arm 51, and a first slot type photoelectric switch 11 corresponding to the position of the first sensing piece 55 is provided on the fixed bracket 1. When the cooking machine needs to stir-fry, the spatula module moves downward, so that the first sensing piece 55 is located in the groove of the first slot type photoelectric switch 11 and blocks the optical axis in the groove of the first slot type photoelectric switch 11. Thus, it can be known that the spatula module has moved in place. At this time, the function of stir-frying can be realized by controlling the operation of the second motor 51, so that the device of the present invention can operate orderly.

[0041] In an embodiment of the present invention, the spatula member includes a spatula bracket 54 and spatula units 55 provided at both ends of the spatula bracket 54. The rotating shaft of the second motor 51 is connected to the spatula bracket 54 through a coupling. The spatula units 55 at both ends of the spatula bracket 54 can better stir-fry the dishes in the cooking pot of the cooking machine.

[0042] In an embodiment of the present invention, the pot lid module includes a pot lid 82 and a second swing arm 81 connected to the pot lid 82. The second swing arm 81 is mechanically connected to the second linkage rod 4. In this way, the pot lid module can be driven to move up and down through the second linkage rod 4.

[0043] In an embodiment of the present invention, a second induction sheet 41 is provided at the top end of the second linkage rod 4, and a second groove type photoelectric switch 61 corresponding to the position of the second induction sheet 41 is provided on the first linkage rod 6. When the pot cover module moves downward, the second induction sheet 41 is located in the groove of the second groove type photoelectric switch 61 and blocks the optical axis in the groove of the second groove type photoelectric switch 61. Thus, it can be known that the pot cover 82 has moved in place and is closed on the pot of the cooking machine.

[0044] In an embodiment of the present invention, a third induction sheet 47 is provided at the bottom end of the second linkage rod 4, and a third groove type photoelectric switch 17 corresponding to the position of the third induction sheet 47 is provided on the fixed bracket 1. When the third induction sheet 47 is located in the groove of the third groove type photoelectric switch 17, it can be known that the pot cover module is still in an upright state.

[0045] In an embodiment of the present invention, the first extrusion assembly includes a first spring 65 and a first extrusion rod 66 connected to the first spring 65. A first installation groove 64 that is communicated with the first through hole 62 and perpendicular to the rotating shaft 3 is provided on the first linkage rod 6. The first spring 65 is installed in the first installation groove 64, and the end of the first extrusion rod 66 presses against the first limiting rod 63. Thus, the first extrusion rod 66 always exerts a force on the first limiting rod 63, and further the first limiting rod 63 can be pressed into the first clamping groove 72; the second extrusion assembly includes a second spring 45 and a second extrusion rod 44 connected to the second spring 45. A second installation groove 46 perpendicular to the rotating shaft 3 is provided on the second linkage rod 4. The second spring 45 is installed in the second installation groove 46, and the end of the second extrusion rod 44 presses against the second limiting rod 42. Thus, the second extrusion rod 44 always exerts a force on the second limiting rod 42, and further the second limiting rod 42 can be pressed into the second clamping groove 74.

[0046] In an embodiment of the present invention, a notch 83 is provided at the position of the pot cover 82 relative to the first linkage rod 6. In this way, it can be prevented that the pot cover 82 is blocked by the first linkage rod 6 and the spatula module and fails to function as a pot cover.

[0047] Thus, by using the device of the present invention, when the cooking machine is cooking, the driving mechanism can be controlled to drive the rotating shaft 3 to rotate clockwise, then the spatula module can be linked to move downward into the pot of the cooking machine, and then the second motor 51 works to rotate the spatula unit 55 to realize the cooking function. When it is necessary to simmer the vegetables with the pot cover 82, the driving mechanism is further controlled to drive the rotating shaft 3 to rotate clockwise, so that the pot cover module moves downward to cover the pot of the cooking machine, achieving the effect of simmering the vegetables. Furthermore, the cooking of the cooking machine is consistent with the daily cooking of people, making the dishes cooked by the cooking machine more flavorful and delicious, and further solving the problems of easy sticking and burning of the existing cooking machine when cooking, and further enhancing the user experience of people.

[0048] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. Obvious changes or modifications derived from the essential spirit of the present invention still fall within the protection scope of the present invention.
